Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an IC chip mounting device, and more specifically, to an IC chip mounting device.
The present invention relates to an IC tray supply device that steadily supplies IC chips to the vicinity of an IC chip mounting device so that the C chip mounting device can reliably and quickly grasp a predetermined IC chip and mount it on an IC board.

BACKGROUND OF THE INVENTION Until now, there have been devices for supplying a predetermined IC chip to the vicinity of an IC chip mounting device that directly mounts an IC chip onto an IC board, such as an IC tray supply device, a tape-shaped component supply device, and even a tape-shaped component supply device. Stick-shaped component supply devices and the like are known.

These supply devices are selected as appropriate depending on the shape and dimensions of the IC chip to be supplied, and in some cases only a single supply device is used independently, but in many cases, In order to supply a wide variety of chips of various shapes or sizes, two or three supply devices are used in conjunction with each other.

Until now, the 12th IC tray supply device
When installing IC trays stacked in multiple stages and stored in the IC tray storage box 10 as shown in the figure, in order to sequentially take out the ICs 1 and 6 from the IC tray 14 installed on the base 12,
Move the tray pull-out arm 20 closer to the ICC tray storage box L side, then drive the arm 20 up and down to hold the base 12 (Fig. 14), and then pull back the arm 20 to remove the base 12. Storage box 1
0 to a predetermined position, and from that position, the IC chip mounting device 24 transports the IC 16 to the board 22.
Tray feeding devices 18 are known.

Problems to be Solved by the Invention However, according to such an IC tray supply device 18, when taking out the IC tray 14 from the IC tray storage box 10, generally a drive source consisting of a heald drive motor, a cylinder, etc. is used. (a drive source that drives the tray pull-out arm 20 back and forth and a drive source that drives it up and down, respectively) are required, and since it is necessary to pull out the IC tray and hold it, the operating mechanism section is required. Due to space constraints, it was not possible to transport the chip close to the substrate. For this reason, in conventional supply devices, the position of the mounting board 22 on the IC chip mounting machine and the position of the IC tray 14 have not been sufficiently close to each other due to the space occupied by the drive system.

Therefore, when a loading machine has to take out all the ICs in the IC tray, the IC chip loading machine has to pick up the ICs over a wide area, and the movement stroke of the loading machine has to be expanded. Therefore, the cost of the chip mounting machine becomes very high, and the distance from the board causes a decrease in mounting work efficiency and a loss of mounting time.

On the other hand, in order to solve these problems, there is also a method in which an XY unit is used in the IC tray supply device and ICs are supplied to a dedicated table for the IC tray supply device (first
However, it is clear that such a method would result in a significant increase in cost due to the increased size of the device.

The purpose of all of these is to accurately supply parts to the IC chip mounting machine, but with conventional IC tray supply devices, if there is a shortage of ICs during operation, it is necessary to replenish the missing ICs. Since the device is larger than a tape-shaped component supply device or the like, the device had to be stopped each time it was replenished.

Furthermore, with conventional IC tray supply devices, when pulling out the IC tray from the IC tray storage box when supplying ICs to a loading machine or when replacing or replenishing ICs, it becomes a hindrance to the pulling operation. Since a positioning member cannot be used on the supply side, a door-shaped stopper 21 that can be rotated when necessary is provided (No. 13).
figure).

When this stopper 21 is used to separate the IC tray storage box from the supply device, a drive source dedicated to the stopper must be separately installed in the storage box to improve operability. It was necessary to provide the necessary large space.

The present invention solves these problems.

Means for Solving the Problems In order to solve the above problems, the IC tray supply device of the present invention holds an IC tray equipped with a plurality of ICs. It consists of a box and an IC tray supply main body that receives the box.

The IC tray storage box has open portions at the front and rear portions. A stopper is provided at the rear opening to prevent the IC tray from being pulled out. Additionally, this stopper provides an activation switch for the IC tray supply body. The main body also includes an IC tray position regulating unit, an IC tray drawer unit, and a transport arm.

Operation: With the above means, the IC tray position regulating unit presses the IC tray in the IC tray storage box against the lever, thereby achieving accurate positioning of the IC tray. Next, the IC tray drawer unit I removes the IC from inside the box.
Pulling out the tray = In order to transport the IC tray to a position adjacent to the IC board, the transport arm starts unloading from the middle of the ICC unit that has been pulled out by the IC tray drawer unit. IC+ inside the IC tray storage box
- When the tray runs out, the operation switch by the stopper is actuated to feed the IC tray into the box while the IC chimp loading device continues to operate.

As a result, the IC tray pulled out by the IC tray pull-out unit 40 engages the hook 83 with the fringe 85 to the front upright part 62 of the base 32 (FIG. 9), and then moves the transfer arm 43 onto the board 41. (Fig. 10). When the base 32 reaches the position closest to the board 41, the base 32 is fixed to the plate member 39. The IC tray is attached to the base stop 87.
collides with and stops at that position.

Thereafter, the IC4 on the IC tray 48 is removed by known means.
6 is carried out to a predetermined position of the substrate 41 which is disposed close thereto.

The operation of the present invention will be described based on FIG.

First, an IC tray 48 with desired ICs 46 placed in predetermined positions is prepared, and the IC tray is mounted onto the base 32.

Next, the base 32 is inserted into the groove 60 in the IC tray storage box 34.
Set multiple sheets. These bases 32 are storage boxes 34
By moving the stopper 70 around the pin 72 to a horizontal position as shown in FIG.
It can be set more easily than 8.

After a predetermined number of bases 32 are housed in the box 34, the stopper 70 is raised, and the groove 78 of the stopper 70 is engaged with the set screw 76 to be fixed as shown in FIG.

The storage box 34 containing the IC tray 48 is moved along the arrow 80 to the storage box moving table 36 of the IC tray supply main body 44.
Transfer it upward and set it on the pin 84 of the table. At this time, the folded portion 74 of the stopper 70 activates the confirmation sensor 82 on the table 36.

Therefore, the sensor 82 is turned "ON".

As a result, the communication between the IC chip loading machine (see numeral 24 in the 12th section) and the IC tray supply device 30 becomes "O".
N LINE”.

When the IC chip loading machine starts the chip loading operation, the storage box 34 placed on the table 36 is loaded with the required IC.
The table 36 is moved up and down along the movement guide shaft 37 to the position where the C tray 48 is supplied, thereby appropriately adjusting the position.

Next, the IC tray position regulating unit 38 (FIG. 3) is activated. That is, after the box 34 is adjusted to a predetermined height, the operating fringe 45 is activated, and the piston rod 65 moves the IC tray pressing piece 51 to the upper left in FIG. push it out. The movement of the pressing piece 5 is restricted by a link 59 pivoting around a pin 57, and the pushing movement is approximately converted into a linear movement in the left horizontal direction. Therefore, the pressing piece 51 collides with the front upright part 62 of the base 32 housed in the box 34, presses it, and presses the base 32 against the stopper 70.

Therefore, the position of the base 32 is always regulated to a constant position.

After that, the cylinder 45 operates in the opposite direction, and the pressing piece 5
] Pull back to the right. Therefore, the piece 51
4, and is pulled back to the lower right position shown by the dashed line in FIG.

Next, by known means, the IC tray drawer unit 40 is linearly approached toward the box 34 along the guide member 67 as shown in FIG. Therefore, the unit main body 71, the tray drawer, and the arm 75 all approach the box 34. When the neck 77 at the tip of the arm 75 fits into the opening 66 of the base 32 as shown in FIG.
stop the linear motion of. Next, the arm cylinder 69 in the main body 71 is operated to rotate the arm 75 clockwise around the pin 73 (FIG. 6). Therefore, the neck portion 77 is
Fit into opening 2. The width dimension (W) of the tip of the neck portion 77 is smaller than the width (L) of the opening of the base 32 but larger than the width (A) of the opening of the raised portion 62, so the neck portion 77 is caught in the opening of the raised portion 62.

Next, in this state, put the drawer unit 40 into the box 34.
pull away from As the unit 40 moves, the neck 77
The base 32 is pulled out from the box 34 as shown in FIG.

The base 32 pulled out from the box 34 is pulled in the direction away from the box 34 above the plate member 39 while its both ends are supported by the guide rails 42. At this time, the position regulating unit 38 is in the lower position as shown by the broken line in FIG. 4, so it does not interfere with the movement of the base 32.

When the base 32 is pulled out to about half the distance of the plate member 39, the base 32 collides with the transport arm 43. At the collision position, the movement of the drawer unit 40 is stopped, and the arm cylinder 69 is actuated to separate the neck portion 77 of the drawer arm 75 from the opening of the base 32.

Next, the cylinder 85 of the transfer arm 43 is activated, and the hook 8
Descend 3. This lowering of the hook 83 engages the raised portion 62 of the base 32 as shown in FIG. While in this engaged state, the transport arm 43 is further moved in a direction away from the box 34. Therefore, the base 32 is further conveyed along the guide rail 42.

The transport arm 43 transports the base 32 until the base 32 collides with a stopper 87 fixed to the rearmost portion of the plate member 39. This position is very close to the tower V, the substrate 41, and is at a distance that allows the IC chip loading machine to quickly and reliably grasp the nip and easily transport it to the substrate. .

After this, a known IC chip mounting machine carries out the IC 46 onto the substrate 41 while the transfer arm 43 holds the base 32 to which the IC 1-ray 48 on which the IC 46 is mounted is fixed via the hook 83. .

In addition, in the present invention, the box 34 set on the table 36 is kept until the moment it is placed on the table 36.
4, the /82 is maintained in the "OFF" state. When the box 34 is placed on the table 36, the OFF LINE state of both the IC tray supply main body 44 and the IC chip mounting machine (however, the IC chip mounting machine only communicates with the main body 44) changes from the OFF LINE state to the RE A D Y state. change.

Next, even if the main body 44 is in the operating state, the stopper fixed to the IC tray storage box 34, that is, the IC tray position regulation plate and storage box presence/absence confirmation sensor detection plate 70, cannot be loosened by loosening the set screw 76. By rotating around the bottle 72, the sensor 82 is turned off. With this operation, the storage box moving table 36 can be brought to a stopped state. Therefore, as shown by the dotted line in Figure 1, the IC
l-Sh-If there is a shortage of ICs in the storage box,
This operation makes it possible to mount the IC tray into the IC tray storage box 364 and to replenish or replace the base 32.

In addition, since only the communication with the table 36 is OFF LINE for the IC chip-equipped machine, it is possible to take components only from other supply devices such as the tape-shaped component supply device or the stain-shaped component supply device. Become.

Effects of the Invention In the present invention, the IC tray supply means is divided into two parts, and the IC tray supply means is divided into two parts.
Since the chip can be transported as close as possible to the C-chip mounting machine, it is possible to improve the loading tact of the IC chip-mounting machine and to downsize the mounting machine, thereby improving accuracy and lowering the price.

Even when replacing all the IC trays in the IC tray storage box or replacing only one +ch tray, communication is established with the IC chip-equipped machine, which improves the operating time of the IC chip-equipped machine. Is possible.

Since the IC tray position regulating device is provided in the same unit as the IC tray transport section, the reliability and operability of the device can be improved.

When replacing the IC tray, this IC tray supply device can take the 0FFLINE state for the IC chip mounted machine, and the storage box moving table does not move during the IC tray replacement, making it extremely safe.

Detecting the presence or absence of the IC tray storage box, stopping the supply when replacing the IC tray, and regulating the position of the IC tray are handled by a single component, so the structure of the device is simple and the device can be made more compact. It is planned.
