Description

Machining device and machining method

Technical Field

The present invention relates to a processing apparatus and a processing method for processing an object to be processed, which moves on a conveyor line, by applying, mounting, cutting, punching, and the like for various purposes such as adhesion, protection, filling, and conduction.

Background

Examples of such processing apparatuses include apparatuses that apply a liquid material to a desired portion of an object to be processed (hereinafter, simply referred to as a "workpiece") moving on a conveyor line, and perform an operation of moving the liquid material applied to the desired portion to a desired state due to the fluidity of the liquid, and examples thereof include an application apparatus that uses a liquid resin as a bottom (underfil) filler or filler, a mounting apparatus that mounts electronic components on a substrate, and an apparatus that punches, cuts, or cuts a workpiece with a drill, a saw, or the like.

More specifically, for example, in an assembly process in a series of semiconductor manufacturing processes, a liquid material ejected from a nozzle is applied to a desired portion of a workpiece for various purposes such as adhesion, protection, filling, and conduction. One form of such coating is coating: a type in which a liquid material is applied from a nozzle to a predetermined position on a workpiece and then flowed in by utilizing the fluidity of the liquid material. For example, the underfill material filling step in the semiconductor manufacturing process is a step of reinforcing a semiconductor by allowing an underfill material made of a liquid resin to flow into a gap between the semiconductor mounted on a substrate and the substrate and then curing the underfill material. In this step, after the underfill material is applied from one side of the semiconductor mounted on the substrate through the nozzle, the underfill material flows into the gap between the semiconductor and the substrate and fills the gap. After the underfill material is filled, it is heated and cured by a heating furnace or the like.

As another example, there is also an application of a sealing type in which the entire semiconductor mounted on a substrate is covered with a liquid resin and protected in a semiconductor manufacturing process. In such a coating step, after a liquid resin is applied from above a semiconductor mounted on a substrate through a nozzle, the applied liquid resin flows along the outer surface of the semiconductor to cover the entire semiconductor. Then, the liquid resin is cured by heating in a heating furnace in the same manner as the underfill material, thereby sealing the entire semiconductor.

In addition to semiconductor manufacturing processes, various fields also perform processes such as a process of filling a member having a recess with a resin material by flowing the resin material into the member, and after applying a liquid material to a desired portion of a workpiece from a nozzle, the liquid material is flowed into the member by utilizing the fluidity of the liquid material.

In such a coating operation, it is preferable to flow the liquid material in a short time for improving the production efficiency, and in one example, when coating the liquid material whose fluidity changes depending on the temperature, the fluidity of the resin material is improved by bringing the workpiece to a desired temperature.

Fig. 10 schematically shows such a conventional coating apparatus.

The coating apparatus 100 includes: a loading unit 104 for moving a supply hopper 110 containing a plurality of workpieces along one side surface of the coating unit 102, and taking out the workpiece a from the hopper 110 and loading the workpiece a on a workpiece input line 112 of the coating unit 102; and an unloading section 106 for storing the workpiece a, which has been subjected to the coating operation by the coating section 102, into the storage hopper 114 from the other side surface of the coating section 102.

The supply hopper 110 stores a plurality of workpieces a for easy conveyance, and has a structure shown in fig. 9, for example. A workpiece a to be coated is taken out from the supply hopper 110, and is subjected to a coating operation by an applicator head B provided with a liquid discharge nozzle or the like at an operation position P located in the middle of the workpiece input line 112, and then is stored in the storage hopper 114.

That is, in the coating apparatus 100 shown in fig. 10, since the workpiece a taken out from the supply hopper 110 of the loading unit 104 is moved to the substantially intermediate operation position P provided on the single conveyor line 112, after a predetermined coating operation is performed, the workpiece a is moved in one direction on the conveyor line 112 and stored in the storage hopper 114 of the unloading unit 106.

The workpiece a conveyed from the loading unit 104 to the operation position on the conveyance line 112 is on standby at the pre-operation standby position Q before reaching the operation position. This is because it takes time to feed the workpiece a to be subjected to the next coating operation from the feed hopper 110 to the operation position P after the workpiece a at the operation position P is conveyed to the unloading section 106 side, and therefore, by causing the workpiece a to be subjected to the next coating operation to stand by at the pre-operation standby position Q while the coating operation is being performed at the operation position P, the time to convey the workpiece a to the operation position can be shortened.

Then, the workpiece a conveyed from the operation position to the unloading section 106 on the conveyance line is temporarily placed on standby at the post-operation standby position R before reaching the unloading section 106. This is because, if the work a for which the coating operation has been completed at the operation position P is to be directly stored in the storage hopper 114 of the unloading section 106, it takes time until the work a is separated from the operation position P, and therefore, by moving the work a to the post-operation standby position R and waiting, it is possible to shorten the time until the work a for which the operation has been completed at the operation position P is moved away from the operation position P.

In particular, the liquid material is flowed in by the fluidity of the liquid material after being coated to reach a desired state, and when such coating is performed, the fluidity is improved by adjusting the temperature of the liquid material, the operation time is shortened, or the temperature of the liquid material can be adjusted more accurately by adjusting the temperature of the workpiece on which the liquid material is coated. For example, the workpiece temperature is adjusted by bringing the heating unit into contact with the workpiece a from below in the operating position (main temperature adjustment), or the temperature is adjusted by bringing the heating unit into contact with the workpiece a from below in the standby position Q before the operation (pre-temperature adjustment), so that it is not necessary to wait until the workpiece reaches a desired temperature in the operating position P, and the production time can be shortened.

Further, if the temperature adjustment (post-temperature adjustment) is performed by bringing the heating unit into contact with the workpiece a from below also at the post-operation standby position R, the workpiece can be output from the operation position P without waiting at the operation position P until the applied liquid material flows into a desired shape, and the time until the next application of the workpiece is started can be shortened.

In addition to the liquid application device described above, as a device for sealing a semiconductor with a resin, there is a device described in japanese laid-open patent publication No. 2003-133345. This resin sealing apparatus performs, at the operation position, a transfer molding operation of mold clamping molding in which resin is injected from both sides of the workpiece, instead of the coating operation, but has a basic configuration in which the workpiece (wiring board) is taken out from the hopper, moved on the conveyor line, and is accommodated in the hopper again after the molding operation, similarly to the liquid coating apparatus described above.

However, in the conventional processing apparatus such as the coating apparatus and the resin sealing apparatus, after the coating and sealing operations for the workpiece a at the operation position P are completed, in order to operate the next workpiece, it is necessary to move the workpiece at the operation position P to the post-operation standby position R and to move the workpiece a at the pre-operation standby position Q to the operation position P. In such an apparatus, it is necessary to position and fix the workpiece so that the workpiece moved to the operation position P does not shake during operation. Therefore, it takes time from the end of the operation on one workpiece to the operation on the other workpiece, and the production speed cannot be increased.

Further, the work is required to be handled carefully so as not to be damaged, and there is a problem that excessively shortening the moving time is rather an obstacle to ensuring the reliability of the final product.

In addition, in order to increase the conveying speed slightly, it is necessary to secure the pre-operation standby position Q and the post-operation standby position R on the workpiece conveying line in addition to the operation position P, and therefore, a space for this purpose is required, resulting in an increase in the size of the entire operation apparatus.

Further, since the loading portion must be disposed at one end of the operation device and the unloading portion must be disposed at the other end, the entire device including the operation device is further increased in size.

Further, when the temperature of the workpiece needs to be adjusted, since it is necessary to provide a temperature adjusting means or a heating means at each of the pre-operation standby position Q, the operation position P, and the post-operation standby position R, power consumption increases, heat is likely to be accumulated in the apparatus, and there is a problem that mechanical components and electronic components of the driving apparatus are adversely affected.

Detailed Description

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 to 4 show an embodiment of a liquid application apparatus as an example of a processing apparatus of the present invention.

In the drawing, the extending direction of the work conveying rail is defined as an X direction, a direction from one side of the work conveying rail to the other side thereof is defined as a Y direction, and a direction perpendicular to the X direction and the Y direction is defined as a Z direction.

Reference numeral 10 denotes an entire liquid coating apparatus which includes a processing section 12 that performs a coating operation on a workpiece a, and a loading/unloading section 14 that supplies a hopper 16 storing the workpiece a to the processing section 12 and discharges the hopper 16 from the processing section 12, and the processing section 12 and the loading/unloading section 14 are arranged in line in the X direction.

The loading/unloading section 14 has a loading/unloading main body as a base, and as shown in fig. 3, a hopper conveying rail 22 and a hopper storage table 24 are disposed on the rear side of the main body. The hopper transport rail 22 is a member for supplying the hopper 16, which stores the work a to be processed from now, to the coating apparatus 10, and includes a rail extending in the Y direction and a not-shown conveyor hung on the rail in the same direction as the rail, and the hopper 16 is moved from the rear to the front on the hopper transport rail 22 by rotating the conveyor by a not-shown driving means. The hopper storage table 24 is positioned above the hopper conveying rail 22, and mounts the hopper 16 that stores the workpiece a after the machining operation is completed.

As shown in fig. 2 and 3, a hopper holder 30 is provided on the front side of the upper surface of the main body of the loading/unloading section 14, and the hopper holder 30 can hold the hopper 16 by vertically holding one claw. The magazine holder 30 is moved in the Z direction by a magazine holder lifting and lowering unit 34, and the magazine holder lifting and lowering unit 34 is moved in the Y direction by a magazine holder Y direction moving unit 32. That is, the hopper gripper 30 is configured to be movable on the YZ plane by the hopper gripper lifting and lowering unit 34 and the hopper gripper Y-direction moving unit 32. Accordingly, the hopper 16 can be moved to a desired position on the YZ plane by the operations of the hopper gripper Y-direction moving unit 34 and the hopper gripper elevating unit 32 in a state of being gripped by the pair of claws of the hopper gripper 30.

On the other hand, the working unit 12 has a working unit main body 40 as a base, and the main body 40 is provided with: a 1 st workpiece conveying rail 42 having a pair of rail portions extending in the X direction at a predetermined interval; and a 2 nd workpiece conveying rail 44 having a pair of rail portions extending in the X direction at the same predetermined interval. The 1 st workpiece conveying rail 42 and the 2 nd workpiece conveying rail 44 are arranged side by side in a state of being separated from each other in the Y direction, and form two workpiece conveying lines.

In addition, although the embodiment is a form in which two workpiece conveying lines are formed by the 1 st and 2 nd workpiece conveying rails each having a pair of rail portions, one workpiece conveying rail may be formed by one rail portion, and two workpiece conveying lines may be formed by two workpiece conveying rails, or "one workpiece conveying line" may be formed by a unit or a passage itself provided with a function of moving one workpiece without using a rail.

As schematically shown in fig. 4, rollers 47 are attached to inner surfaces of both end portions (only one side is shown in fig. 4) of the pair of rail portions in each of the workpiece conveying rails 42 and 44, and an endless belt 46 is attached between the rollers 47 in the extending direction of the workpiece conveying rails. The workpiece a is mounted on the two endless conveyors 46, and by driving a driving means (not shown) connected to the roller 47, the roller 47 and the endless conveyor 46 are rotated, whereby the workpiece a moves in the X direction on the workpiece conveying rail.

In addition, in the present embodiment, only one workpiece is moved at a time in one workpiece transport line, and therefore, one workpiece transport line is constituted by one drive unit and a pair of endless conveyors. A plurality of drive units and a plurality of pairs of endless conveyors may be employed in one work conveying line as necessary.

At the end portions of the 1 st and 2 nd workpiece transfer rails 42 and 44 on the loading/unloading section 14 side, a 1 st workpiece gripper 48 and a 2 nd workpiece gripper 50 for holding and fixing the workpiece a and moving the workpiece a are disposed, respectively.

Each of the work holders 48 and 50 is composed of a claw portion for holding the work a and a unit (not shown) for moving the claw portion in the X direction. With this configuration, the work grippers 48 and 50 can take out one workpiece a from the magazine 16 positioned at the end of each of the workpiece conveying rails 42 and 44 and load the workpiece a onto the workpiece conveying rails 42 and 44 in the vicinity of the end of the loading/unloading section. Further, the workpieces a near the end portions on the loading/unloading portion side on the workpiece conveying rails 42, 44 can be accommodated in the hoppers 16 positioned at the end portions of the workpiece conveying rails 42, 44. In this embodiment, the workpiece a is taken out and stored by one of the grippers 48 and 50.

An operation position (indicated by a broken line) for processing (coating) the workpiece a is provided at a substantially middle portion of each of the workpiece conveying rails 42 and 44. The endless belts 46, 46 and the drive unit of the respective workpiece conveying rails 42, 44 also function as a stop unit, that is: when the workpiece a reaches the operation position, the drive unit is stopped, and the rotation of the endless belts 46, 46 is stopped. In addition, a workpiece fixing means, not shown, is disposed at the operation position. When the work a conveyed on each of the work conveying rails 42, 44 stops at the operation position, the work fixing unit fixedly holds the work a to the operation position without the work a wobbling in all of the X direction, the Y direction, and the Z direction.

Further, below each of the workpiece conveying rails 42 and 44 in the above-described operation positions, a 1 st heating unit 52 and a 2 nd heating unit 54, for example, heaters, which correspond to temperature adjusting units, are provided, respectively. The heating units 52 and 54 are provided on the elevating units 53 and 55, and when the workpiece a is fixedly held at the operation position, the heating unit 52 or 54 is raised to contact the bottom surface of the workpiece a, thereby heating the workpiece a to a desired temperature.

Above the processing portion 12, the following mechanisms are arranged: an application head 70 as a part of an application device which is a unit for processing the workpiece a and a mechanism for freely moving the application head 70 in the X direction, the Y direction, and the Z direction, for example, a 3-axis control robot, are fixed/held.

The 3-axis control robot is constituted by, for example: a Z-direction moving unit 62 including an arm 63 extending in the Z-direction, and moving the coating head 70 in the Z-direction with respect to the arm 63; an X-direction moving unit 60 including an arm 61 extending in the X-direction, and moving a Z-direction moving unit 62 in the X-direction with respect to the arm 61; a guide rail 58 extending in the Y direction; a Y-direction moving unit 56 that moves the X-direction moving unit 60 on the guide rail 58 in the Y direction; and a control device (not shown) for controlling the coating device fixed to the coating head 70 according to a preset coating program so that the coating head 70 is moved in the Z direction, the Z-direction moving unit 62 is moved in the X direction, and the X-direction moving unit 60 is moved in the Y direction, so that the liquid can be ejected to a desired position of the workpiece a.

Specifically, the Z-direction moving means 62 is composed of an arm 63 extending in the Z-direction, means (not shown) for supporting the applicator head 70 so as to be slidable in the up-down direction with respect to the arm 63, and drive means (not shown) for moving the applicator head 70, and the applicator head 70 is moved in the up-down direction (Z-direction) by the drive of the drive means.

The X-direction moving means 60 is constituted by an arm 61 extending in the X-direction, means (not shown) for supporting the Z-direction moving means 62 so as to be slidable in the horizontal direction with respect to the arm 61, and drive means (not shown) for moving the Z-direction moving means 62, and the Z-direction moving means 62 is moved in the horizontal direction (X-direction) by the drive of the drive means.

The Y-direction moving unit 56 is configured by a unit (not shown) that supports the X-direction moving unit 60 so as to be slidable in the Y direction with respect to a guide rail 58 extending in the Y direction, and a driving unit (not shown) that moves the X-direction moving unit 60, and the X-direction moving unit 60 is moved in the Y direction by the driving of the driving unit.

The guide rail 58 is disposed on an arch 80, the arch 80 is disposed on an end portion of the processing unit main body 40 on the loading/unloading unit 14 side across the work conveyor lines 42, 44, the Y-direction moving unit 56 is disposed on an arch 81, and the arch 81 is disposed on an end portion of the processing unit main body 40 on the opposite side to the loading/unloading unit 14 side across the work conveyor lines 42, 44. In this way, the movement range of the X-direction moving unit 60 determined by the Y-direction moving unit 56 and the guide rail 58 crosses the workpiece transfer line 42.

Specifically, one end of the X-direction moving unit 60 is located above the Y-direction moving unit 56, and the X-direction moving unit 60 is moved in the Y-direction by driving the Y-direction moving unit 56. Thus, the other end of the X-direction moving unit 60 is placed on the guide rail 58 to be slidable in the Y-direction. That is, when one end of the X-direction moving unit 60 is to be moved in the Y-direction by the driving of the Y-direction moving unit 56, the other end of the X-direction moving unit 60 is slidably moved on the guide rail 58, and the X-direction moving unit 60 is moved in the Y-direction without rattling.

That is, the coating head 70 can be moved to desired positions in the X direction, the Y direction, and the Z direction by operating the Y direction moving unit 56, the X direction moving unit 60, and the Z direction moving unit 62.

Here, the X-direction moving means 60, the Y-direction moving means 56, and the Z-direction moving means 62 may be configured to include a ball screw, or may be configured to include a linear motor, for example. Alternatively, the 2 nd Y-direction moving means may be used instead of the guide rail 58, and the X-direction moving means 60 may be moved by 2 moving means. The 2 nd Y-direction moving means may be configured to include a ball screw or a linear motor, as in the Y-direction moving means 56. In addition, the 2 nd Y-direction moving means may be controlled independently of the Y-direction moving means 56, and in this case, the moving direction of the Z-direction moving means 62 may be changed by inclining the direction of the X-direction moving means 60.

In this embodiment, the coating head 70 is provided with a carriage 72, a laser displacement sensor 74, and a camera 76, which are configured to hold the liquid storage ejector 71 so as to be exchangeable with each other.

The ejector 71 held by the above-described bracket 72 has a nozzle 73 at its lower end, and its upper end is communicated to the distributor via a not-shown pipe. Air of a desired pressure is supplied from the dispenser to the ejector 71 through a pipe, and the liquid stored in the ejector 71 can be ejected from the nozzle 73.

The laser displacement sensor 74 receives laser light emitted from the light source and reflected on the surface of the workpiece a as the measurement target, thereby measuring the distance to the workpiece a. The camera 76 is used to photograph the workpiece a located at the operation position and grasp the state of the workpiece a.

Hereinafter, an application method using a liquid application apparatus as an example of the processing apparatus of the present invention will be described with reference to fig. 5 and 6.

In this embodiment, the work conveying rails 42 and 44 are basically operated in the order of the work input step, the machining step, and the work output step, but for convenience of explanation, the steps will be explained first.

(1) Work input process

The workpiece a mounted on the workpiece conveying rails 42 and 44 near the end portions on the loading/unloading section 14 side is moved on the workpiece conveying rails 42 and 44 from the end portions on the loading/unloading section 14 side to the operation position by driving the conveyor belts 46 of the workpiece conveying rails 42 and 44. When the workpiece a reaches the operation position, the driving of the conveyor 46 is stopped, and the workpiece a is positioned and fixed by a fixing means not shown.

In the workpiece input step, the heating units 52 and 54 are raised from below the workpiece a to contact the bottom surface of the workpiece a, thereby heating the workpiece a (this heating is referred to as preheating).

(2) Work processing procedure

The X-direction moving means 60, the Y-direction moving means 56, and the Z-direction moving means 62 are operated to move the nozzle 73 of the coating head 70 to a desired position on the workpiece a, supply air from the dispenser into the ejector 71, and eject liquid from the nozzle 73 to perform a desired coating operation such as underfill or filling. If necessary, the X-direction moving unit 60, the Y-direction moving unit 56, and the Z-direction moving unit 62 may be driven to move the coating head 70 in the X-direction, the Y-direction, or the Z-direction during the ejection. In this step, the result of measuring the distance to the surface of the workpiece by the laser displacement sensor 74 and the result of imaging the workpiece a by the camera 76 can be reflected in the coating operation.

In the workpiece processing step, the heating units 52 and 54 are brought into contact with the bottom surface of the workpiece to heat the workpiece (this heating is referred to as main heating) in order to improve the fluidity of the liquid after application.

(3) Work output process

The workpiece a at the operation position is moved from the operation position to the end portion on the loading/unloading section 14 side on the workpiece conveying rails 42 and 44 by being driven in the direction opposite to the carrying-in process by the conveyor belts 46 of the workpiece conveying rails 42 and 44 after the positioning and fixing of the workpiece a by the fixing means are released while the heating means 52 and 54 are lowered to release the contact with the workpiece a. When the workpiece a reaches the vicinity of the end portions on the workpiece conveying rails 42 and 44, the movement of the workpiece a is stopped by the driving of the stop conveyor 46.

In the workpiece discharge step, the workpiece a in the operation position is kept on standby for a certain time at the operation position before the heating units 52 and 54 are lowered to release the contact with the workpiece a, and is heated by the heating units 52 and 54 even after the machining step (this heating is referred to as after-heating).

Next, a liquid application method using the liquid application apparatus will be described.

First, the following steps are performed to bring the workpiece a into a state where the workpiece a can be taken out from the magazine 16 storing the workpiece a to the workpiece conveying rails 42 and 44.

This is because, first, the hopper 16 containing the work a to be coated from now is moved forward from behind on the hopper conveying rail 22. The hopper gripper 30 is positioned at the front end of the hopper conveying rail 22 by driving the hopper gripper lifting unit 34 and the hopper gripper Y-direction moving unit 32, and the hopper 16 is gripped and held by the claws of the hopper gripper 30. Then, the magazine holder elevating unit 34 and the magazine holder Y-direction moving unit 32 are driven to position the magazine 16 at the end of the workpiece conveying rail.

Then, the work a is taken out from the hopper 16 and subjected to a coating operation. The coating operation will be described with reference to the operation explanatory diagrams (steps 1 to 13) shown in fig. 5 to 6.

(step 1)

In the 1 st workpiece conveying rail 42, the 1 st workpiece gripper 48 takes out an unprocessed workpiece (workpiece a) from the magazine 16 and mounts it on the 1 st workpiece conveying rail 42 (fig. 5 (a)).

(step 2)

In the 1 st workpiece conveying rail 42, the workpiece a is subjected to the input process and the preliminary heating. The hopper 16 moves to the vicinity of the end of the 2 nd workpiece conveying rail 44. The movement of the hopper 16 is performed by driving the hopper holder lifting and lowering unit 34 and the hopper holder Y-direction moving unit 32 (fig. 5 (b)).

(step 3)

In the 1 st workpiece input rail 42, the coating head 70 is moved to an operation position of the 1 st workpiece conveying rail 42 (i.e., on the workpiece a), a machining process is performed on the workpiece a, and the workpiece a is subjected to main heating. The movement of the coating head 70 is performed by the X-direction moving means 60, the Y-direction moving means 56, and the Z-direction moving means 62.

In the 2 nd workpiece transport rail 44, the 2 nd workpiece gripper 50 takes out an unprocessed workpiece (workpiece B) from the magazine 16 and mounts it on the 2 nd workpiece input rail 44 (fig. 5 (c)).

(step 4)

In the 1 st workpiece conveying rail 42, the machining process and the main heating of the workpiece a are continued.

In the 2 nd workpiece conveying rail 44, the workpiece B is subjected to the input process and the preliminary heating.

The hopper 16 moves to the vicinity of the end of the 1 st workpiece conveying rail 42 (fig. 5 d).

(step 5)

In the 1 st workpiece conveying rail 42, the workpiece a is post-heated.

In the 2 nd workpiece conveying path 44, the coating head 70 having finished the machining operation in the 1 st workpiece conveying path 42 is moved to the operation position of the 2 nd workpiece conveying path 44 (that is, on the workpiece B), and the workpiece B is subjected to the machining process and the main heating is performed (fig. 5 (e)).

(step 6)

In the 1 st workpiece conveying rail 42, the workpiece a is subjected to the carry-out process.

In the 2 nd workpiece conveying rail 44, the machining process and the main heating of the workpiece B are continued (fig. 5 (f)).

(step 7)

In the 1 st workpiece conveying rail 42, the 1 st workpiece gripper 48 receives the workpiece a that has completed the carry-out process in the 1 st workpiece conveying rail 42 into the hopper 16.

In the 2 nd workpiece conveying path 44, the machining process and the main heating of the workpiece B are continued (fig. 6 (a)).

(step 8)

In the 1 st workpiece conveying rail 42, an unprocessed workpiece (workpiece C) is taken out from the magazine 16 by the 1 st workpiece gripper 48 and mounted on the 1 st workpiece conveying rail 42.

In the 2 nd workpiece conveying rail 44, the machining process and the main heating of the workpiece B are continued (fig. 6 (B)).

(step 9)

In the 1 st workpiece conveying rail 42, the workpiece C is subjected to the input process and the preliminary heating.

In the 2 nd workpiece conveying rail 44, the machining process and the main heating of the workpiece B are continued.

The hopper 16 moves to the vicinity of the end of the 2 nd workpiece conveying rail 44 (fig. 6 c).

(step 10)

In the 1 st workpiece conveying path 42, the coating head 70, which has finished the machining operation in the 2 nd workpiece conveying path 44, is moved to the operation position of the 1 st workpiece conveying path 42 (i.e., on the workpiece C), and the workpiece C is subjected to the machining process and the main heating is performed.

In the 2 nd workpiece conveying rail 44, the workpiece B is post-heated (fig. 6 d).

(step 11)

In the 1 st workpiece conveying rail 42, the machining process and the main heating of the workpiece C are continued.

In the 2 nd workpiece conveying rail 44, the workpiece B is subjected to the carry-out process (fig. 6 (e)).

(step 12)

In the 1 st workpiece conveying rail 42, the machining process and the main heating of the workpiece C are continued.

In the 2 nd workpiece conveying rail 44, the 2 nd workpiece gripper 50 receives the workpiece B, which has completed the carry-out step in the 2 nd workpiece conveying rail 44, into the hopper 16 (fig. 6 (f)).

(step 13)

The machining process and the main heating are continued in the 1 st workpiece conveying rail 42.

In the 2 nd workpiece conveying rail 44, the 2 nd workpiece gripper 50 takes out an unprocessed workpiece (workpiece D) from the magazine 16 and mounts it on the 2 nd workpiece input rail 44 (fig. 6 g).

After the above steps 1 to 13 are completed, the process returns to step 4 again, and the same operation is repeated. In addition, when returning to step 4, the workpiece a is replaced with the workpiece C, and the workpiece B is replaced with the workpiece D.

After the machining operation is completed for all the workpieces in the hopper 16, the hopper gripper 30 places the held hopper 16 on the hopper storage table 24 by driving the hopper gripper lifting and lowering unit 34 and the hopper gripper Y-direction moving unit 32. Then, the same operation is repeated while holding the other hopper 16 on the hopper conveying rail 22.

The hopper 16 placed on the hopper storage table 24 is collected by an operator, a robot, or the like, not shown, and sent to a subsequent process of the production line.

In this embodiment, in order to shorten the time required for taking out and storing the workpiece by shortening the moving distance of the workpiece, when the workpiece is taken out from the magazine by the workpiece gripper, the magazine is positioned by the magazine lifting and lowering means so that the workpiece to be taken out from the magazine from now on is positioned at the same height as the workpiece conveying rail. Similarly, when a workpiece is stored in the magazine by the work retainer, the magazine is positioned by the magazine lifter so that the position in the magazine where the workpiece is to be stored is at the same height as the workpiece conveying rail.

By performing such an operation, when the processing step performed in the 1 st workpiece input path 42 is completed and the coating head 70 is moved to the 2 nd workpiece input path 44, the input step in the 2 nd workpiece input path 44 is already completed, and therefore the processing step can be immediately performed in the 2 nd workpiece input path 44.

Similarly, when the machining process performed in the 2 nd workpiece input path 44 is finished and the coating head 70 is moved to the 2 nd workpiece input path 44, the input process of the 1 st workpiece input path 42 is finished, and therefore the machining process can be immediately performed in the 1 st workpiece input path 42. That is, the time waiting for the start of machining in the workpiece input process can be set to zero, and the production efficiency can be improved.

In this embodiment, after the machining operation of one workpiece is completed, it is necessary to perform the operation of moving the coating head on the other workpiece conveying rail until the machining of the other workpiece is performed, but the movement can be significantly shortened as compared with the time taken for one workpiece conveying rail to carry out the workpiece after the machining operation is completed and the next workpiece to be carried in. The reason for this is that the workpiece is small and precise, is easily damaged, and cannot be conveyed at high speed in order to avoid a trouble.

Further, since a small number of machining units move between the workpiece conveying rails, the entire apparatus can be configured to be not so large in size even if the number of workpiece conveying rails is increased.

In addition, by providing a plurality of workpiece conveying rails, even if the pre-operation standby position and the post-operation standby position are not provided in front of or behind the operation position, the pre-operation standby and the post-operation standby can be performed at the operation position. Thus, the operation efficiency is improved, and the entire apparatus can be miniaturized.

Further, by providing a plurality of workpiece conveying rails, the pre-operation standby position and the post-operation standby position are eliminated, and the workpiece after the end of the machining operation can be carried out on the workpiece input side.

Further, since the number of heating units can be reduced, power consumption can be suppressed, heat is less likely to remain in the apparatus, and the influence of heat on other mechanical and electronic components in the apparatus can be reduced.

Further, with the configuration in which the heating unit is disposed only at the operation position, it is possible to heat the workpiece not only during the machining operation (main heating), but also before the machining operation (preliminary heating) and after the machining operation (post heating). In the case where the machining operation is a coating operation in which a liquid material is supplied from a nozzle to a workpiece and then the liquid material is caused to flow to a desired state, such as an underfill operation, a filling operation, or a sealing operation, the workpiece can be heated to a temperature at which the liquid material is likely to flow by preheating, and the flow of the liquid material supplied to the workpiece can be promoted by post-heating.

Fig. 7 to 8 show another embodiment of a liquid application apparatus as an example of the processing apparatus of the present invention.

In the present embodiment, the loading unit 14A is disposed on the left side of the processing unit 12 in front view, and the unloading unit 14B is disposed on the right side of the processing unit 12 in front view.

In this case, the workpiece a after the machining operation is moved to the unloading section 14B side opposite to the loading section 14A in the unloading step. Then, the workpiece a is accommodated in the hopper 16 of the unloading section 14B by the output workpiece gripper 48B or 50B (accommodating unit) provided at the end of the workpiece conveying rail 42 or 44 on the unloading section 14B side.

The loading unit 14A and the unloading unit 14B have substantially the same structure as the loading/unloading unit 14 in embodiment 1.

In the loading section 14A, the magazine 16 containing unprocessed workpieces is conveyed from the magazine conveying rail 22A by the input workpiece gripper 48A or 50A (take-out means). The hopper 16, from which the workpiece is emptied, is placed on the hopper storage table 24A of the loading unit 14A.

In the unloading section 14B, an empty hopper is conveyed from the hopper conveying rail 22B. The magazine 16 that stores the workpiece after the machining operation is placed on the magazine storage table 24B of the loading unit 14B.

In the above-described embodiment 1, since the hopper gripper 30 of the loading/unloading section 14 must hold the hopper 16 until the workpiece processing operation is finished and the hopper is returned again after the last workpiece is taken out of the hopper 16, it is not possible to place the empty hopper 16 being held on the hopper storage table 24 and hold a new hopper 16 from the hopper conveying rail 22 in which an unprocessed workpiece is stored.

Therefore, a waiting time occurs in which the workpiece cannot be supplied to the workpiece conveying rail 42 or 44 until the machining operation of the workpiece is finished and the workpiece is returned to the hopper 16 again.

In contrast, in embodiment 2, since the workpieces taken out from the hopper 16 of the loading section 14A are stored in the other hopper 16 of the unloading section 14B, immediately after all the workpieces in the hopper are taken out, the hopper gripper 30 of the loading section 14A places the empty hopper 16 being held on the hopper storage table 24A, and then can hold the other hopper 16 in which the unprocessed workpieces are stored from the hopper conveying rail 22A.

Therefore, the work can be supplied to the work conveying rail 42 or 44 without interruption, further increasing the production speed.

In the present invention, in the above-described embodiments 1 and 2, the workpiece conveying rails 42 and 44 having the conveying mechanism using the conveyor belt 46 are used as the workpiece conveying lines, but the present invention is not limited to this, and other mechanisms such as a mechanism that moves the workpiece holding table in the X direction by a ball screw or a mechanism that moves in the X direction while holding a part of the workpiece may be used.

Further, as the temperature adjusting means, a heating means composed of a heater is used, but, if necessary, a cooling means or a combination of a heating means and a cooling means may be used.

In the above-described embodiment, the processing unit is a liquid application device having a nozzle, but the processing unit is not limited to this, and a device for placing a component on a workpiece, a device for cutting/cutting a workpiece, or the like may be used.

In addition, as the taking-out means for moving the workpiece from the hopper to the workpiece conveying rail, in addition to the work clamp, a pushing-out means may be used which moves the rear end portion of the workpiece along the workpiece conveying rail by pressing the rear end portion of the workpiece from the side of the hopper opposite to the side of the workpiece conveying rail. Similarly, the storage unit may be a push-out unit that moves the workpiece from the conveying rail to the hopper by pressing the rear end portion of the workpiece. Further, as the taking-out means and the storing means, means for moving the claw hook by being engaged with a hole, a recess, or the like provided in the workpiece may be employed.

In another embodiment of the present invention, a liquid material application apparatus may be embodied as a liquid material application apparatus including: an application head having a nozzle that ejects a liquid; a workpiece storage section for storing a workpiece; and a work conveying section provided below the coating head section, conveying the work supplied from the work storage section to a coating operation position of the coating head section, and conveying the work to the work storage section after the coating operation is completed. The coating head includes: a coating head having a nozzle for ejecting a liquid material; an up-down moving unit for moving the coating head up and down; a 1 st moving unit which has a beam and moves the up-down moving unit in a 1 st direction which is an extending direction of the beam; and a 2 nd moving unit extending in a 2 nd direction different from the extending direction of the beam and moving the beam in the 2 nd direction. The work conveying unit is preferably in the form of two or more conveying lines for conveying the work.

In the liquid applying apparatus, the receiving portion is preferably disposed at one end of the conveying portion.

In the liquid coating apparatus, it is preferable that a heating/cooling unit for heating or cooling the workpiece is provided below the workpiece transport line located at the coating operation position.

Preferably, the 1 st direction is the same direction as the direction in which the conveyor line is laid.

In the processing apparatus of the present invention, the operation of the driving unit, the adjusting unit such as the heating unit and the dispenser, and the various sensors of each member is controlled by transmitting and receiving signals to and from a control unit (not shown). The control unit may be a known component generally mounted on such a device, and the configuration and arrangement thereof are not particularly limited as long as the control unit can control the above components to perform a desired operation.

The control unit used in the present invention may be configured to be controlled by transmitting and receiving signals between control circuits provided for the respective components, by a control circuit provided for each component, or by transmitting and receiving signals to and from each component by one control circuit, or by a combination of these control circuits.

The form of the control unit is mainly a structure such as a personal computer or a structure such as an electronic circuit board provided in a housing of the device.

The control content of each component may be determined by a hardware configuration such as an electronic circuit or may be determined by a software configuration such as a program. Even with the same hardware configuration, the control content can be changed by merely changing software such as a program.

The control unit may be provided with an input unit for inputting control contents and a display unit for displaying control results, if necessary.
