[Timekeeping part]
The timekeeping unit 12 is a functional unit that measures the passage of time. The timekeeping unit 12 measures the elapsed time based on, for example, a reference vibration of an oscillator or the like. In the present embodiment, when the control unit 10 commands the actuator to move forward or backward, the timekeeping unit 12 measures the operation time on the outward path or the return path. Here, the outward path is the path from the last retracted position La to the most advanced position Lb of the piston rod L. The return path is the path from the piston rod L moving from the most advanced position Lb to the last retracting position La.

In the present embodiment, the operation time of the outward route is the time from the time when the control unit 10 commands the actuator to move forward to the time when the second sensor Sb detects the proximity of the detected unit Ls. In the following, the operation time of the outbound route is referred to as the outbound route time.

The abnormality detection unit 11 has the outbound time and the inbound time for each operation of each actuator measured by the timekeeping unit 12, the reference range of the outbound time preset for each actuator (hereinafter referred to as the outbound reference), and the inbound route. Contrast with the time reference range (hereinafter referred to as the return reference). Then, an actuator in which at least one of the outward route time and the return route time deviates from the outward route reference or the return route reference (reference range) is specified as an abnormal actuator.

As for the outward route reference and the return route reference, the values corresponding to each actuator are stored in the storage unit 8. As the outward route reference, for example, a lower limit value larger than zero and an upper limit value larger than the lower limit value are stored, and a reference range equal to or more than these lower limit values and less than or equal to the upper limit value is defined as the reference range in the outward route reference. Similar to the outward route standard, the return route standard also stores a lower limit value larger than zero and an upper limit value larger than the lower limit value, and a reference range equal to or more than these lower limit values and less than or equal to the upper limit value is defined as a reference range in the return route standard. In the following, when the return route standard and the outward route standard are comprehensively explained, they may be described simply as the reference range.

An actuator for which a reference range is not set is not a target specified as an abnormal actuator by the abnormality detecting unit 11. In the present embodiment, an actuator in which the corresponding outward route reference or return route reference is not stored in the storage unit 8, or an actuator in which zero is stored as the outward route reference or return route reference is not a target to be specified as an abnormal actuator.

[Control unit]
As described above, the control unit 10 is a functional unit that controls the operation of each unit of the resin molding apparatus 100. The control unit 10 executes the following abnormality processing as one of the operation controls of each unit of the resin molding apparatus 100. The error handling means that when any actuator is identified as an abnormal actuator by the abnormality detection unit 11, a procedure corresponding to the actuator identified as the abnormal actuator is selected from a plurality of preset device stop processing procedures. This is a stop control for stopping the resin molding apparatus 100. The plurality of device stop processing procedures are stored in the storage unit 8 in advance. The device stop processing procedure in the present embodiment is different from the normal (normal) resin molding device 100 stop processing procedure, which is executed when the user inputs an end instruction or when the work is completed. It is a procedure, which is a so-called stop processing procedure in the case of performing an emergency stop or a preventive stop. The device stop processing procedure will be described later.

[Touch panel]
The touch panel 9 is an input interface that receives input of operation commands related to molding in the resin molding apparatus 100 and information related to abnormality processing from the user, and is a display device that displays various output information of the resin molding apparatus 100. The touch panel 9 is, for example, a touch panel device that realizes both the display of various output information of the resin molding apparatus 100 and the reception of input settings from the user. Instead of the touch panel 9, a combination of different input interfaces and display devices may be used.

The touch panel 9 receives the user's input regarding the outward path reference and the return path reference of each actuator and stores them in the storage unit 8. Further, the touch panel 9 is a user's selection instruction (an example of abnormality processing-related information) as to which device stop processing procedure is used to stop the resin molding apparatus 100 when each actuator is detected as an abnormal actuator. The input is received and stored (set) in the storage unit 8.

In the present embodiment, the actuator into which at least one of the outward path reference and the return path reference is input by the touch panel 9 is stored in the storage unit 8 so as to be a specific target as an abnormal actuator. If the user does not input a selection instruction as to which device stop processing procedure is used to stop the resin molding device 100 when the actuator is detected as an abnormal actuator, the storage unit 8 is used. The pre-stored selection settings (presets) are selected in place of the user's selection instructions.

In the present embodiment, the touch panel 9 displays the outward path time and the return path time for each operation of each actuator specified as an abnormal actuator as one of the displays of various output information. In addition, when the execution of the abnormal processing is started, the fact and the execution content of the abnormal processing are displayed.

[Comprehensive explanation of the operation of resin molding equipment]
The molding method and molding operation of the lead frame 3 by the resin molding apparatus 100 will be comprehensively described. First, the lead frame supply unit 42 pushes out the lead frame 3 from the in-magazine 7 and conveys it to the alignment mechanism 70. When the lead frame 3 is placed, the alignment mechanism 70 rotates the rotary disk 70a to align the lead frames 3 so as to be in a state suitable for picking up the lead frame 3 by the loader 40. Next, the loader 40 moves above the alignment mechanism 70. The loader pickup unit 40a of the loader 40 picks up the lead frame 3. Next, the resin 39 is picked up from the resin supply device 79. The loader 40 moves from the in-module M1 to the mold module M2 along the guide G, and carries the lead frame 3 and the resin 39 into the molding mold 20. The loader 40 carries the lead frame 3 and the resin 39 into the molding die 20, and then returns to the in-module M1. The loader 40 returning to the in-module M1 subsequently picks up the lead frame 3 extruded from the lead frame supply unit 42, picks up the resin 39 from the resin supply device 79, and the lead frame 3 previously carried into the molding die 20 Wait until it is molded. As shown in FIG. 1, when there are a plurality of mold modules M2, the loader 40 may move to another unmolded mold module M2 and carry the lead frame 3 and the resin 39 into the mold 20. good. The lead frame supply unit 42, the resin supply device 79, and the loader 40 repeat the same operation thereafter.

When the lead frame 3 and the resin 39 are carried in, the molding mechanism 2 closes the upper mold 21 and the lower mold 22 of the molding mold 20 by the mold clamping mechanism 48. Then, when the resin 39 is melted by the preheated molding die 20, the resin 39 is pushed out into the cavity 21b by the plunger 23. As a result, the lead frame 3 is molded with the resin 39 to obtain a molded product 30. When the molded product 30 is obtained, the molding mechanism 2 opens the upper mold 21 and the lower mold 22.

The unloader 44 moves from the out module M3 to the mold module M2 and picks up the molded product 30 from the molding die 20. The molding mechanism 2 that has picked up the molded product 30 waits for the next lead frame 3 to be carried in by the loader 40. After that, the molding mechanism 2 repeats the same operation.

The unloader 44, which has picked up the molded product 30 from the molding mold 20, moves from the mold module M2 to the out module M3 and carries the molded product 30 into the gate break mechanism 71. The molded product 30 is gate-breaked by the gate-break mechanism 71. The processed molded product 31 is picked up by the unloader 44, transported to the out magazine 72, and accommodated therein. The unloader 44 waits until the molding mechanism 2 molds the next molded product 30. After that, the unloader 44 repeats the same operation.

[Device stop processing procedure]
In the present embodiment, at least the first device stop processing procedure and the second device stop processing procedure are stored (preset) in the storage unit 8 as the device stop processing procedure when the abnormal actuator is specified.

In the first device stop processing procedure, the lead frame 3 and the resin 39 are stopped (prohibited) from being carried into the molding die 20 by the lead frame supply unit 42 and the loader 40, and the lead frame 3 is molded in the molding die 20. If it is in the middle of the process, it is a stop processing procedure for stopping the operation of the resin molding apparatus 100 without carrying out the molded product 30 from the molding die 20 after molding the lead frame 3 being molded. The concept of being molded includes the case where the lead frame 3 and the resin 39 have already been carried into the molding die 20.

When the first device stop processing procedure is executed, the control unit 10 displays the fact that the first device stop processing procedure has started (an example of the execution content of the abnormal processing) on the touch panel 9 as one of the displays of various output information. To display. The fact that the execution of the first device stop processing procedure has started is displayed as, for example, an "error display".

In the first device stop processing procedure, even if the lead frame 3 is being carried into the mold 20, the lead frame 3 and the resin 39 are stopped from being carried into the mold 20. Note that the lead frame 3 is being carried in from the time when the lead frame supply unit 42 pushes out the lead frame 3 from the in-magazine 7 until immediately before the lead frame 3 and the resin 39 are carried into the molding die 20 by the loader 40. The state of.

In the first device stop processing procedure, after molding the lead frame 3 during molding, the molded product 30 is kept in the molding mold 20 as it is. The actuator identified as an abnormal actuator returns (shifts) to a predetermined stop state when the operation of the resin molding apparatus 100 is stopped. The predetermined stopped state is, for example, the stopped state of the actuator in the stopped state of the normal (normal) resin molding apparatus 100. By stopping in the normal stopped state in this way, the actuator can be properly inspected and maintained. Further, by stopping in such a normal stopped state, when the molding operation is started (restarted) after the actuator is inspected or the like, the stopped state affects the start of the molding operation of the resin molding apparatus 100. Instead, the resin molding apparatus 100 can be normally started (restarted).

In the preset, the first device stop processing procedure is that the actuator 50 for carrying the lead frame 3 into the molding die 20, such as the actuator 50 of the loader 40 or the actuator 52 of the lead frame supply unit 42, is abnormal by the abnormality detection unit 11. It is set to be selected and executed when it is identified as an actuator. Since the loader 40 and the lead frame 3 conveyed by the lead frame supply unit 42 are not yet molded of the resin 39 and are fragile, if an abnormality occurs in the actuators 50 and 52, for example, the lead frame 3 and the bonding wire 3b may be damaged. It may be deformed or damaged, and there is a risk of manufacturing (molding) an inappropriate molded product 30. Hereinafter, the molded product 30 in which the lead frame 3 and the bonding wire 3b are deformed, damaged, or otherwise defective or may occur is also referred to as an “inappropriate molded product 30”.

When the outward path reference of the actuator 52 is deviated from the mode in which the outward path time is less than the lower limit value, the speed at which the actuator 52 pushes out the lead frame 3 becomes too fast. As a result, an excessive force is applied to the extruded lead frame 3, and for example, the lead frame 3 and the bonding wire 3b may be deformed or damaged. As a result, there is a risk of manufacturing (molding) an inappropriate molded product 30. Similarly, when the outward path time of the actuator 50 is less than the lower limit value and the outward path reference is deviated, the speed of transporting the lead frame 3 becomes too high. As a result, an excessive force may be applied to the lead frame 3 during transportation, and the lead frame 3 and the bonding wire 3b may be deformed. However, by executing the first device stop processing procedure when the actuators 50 and 52 are identified as abnormal actuators in this way, it is possible to prevent the manufacture of an inappropriate molded product 30. In addition, preventive maintenance of the actuator identified as an abnormal actuator can be performed. If the outward path reference of the actuators 50 and 52 is less than the lower limit value (abnormality that the operation time is too fast), the loader 40 and the lead frame supply unit 42 are accompanied by the operation of the actuators 50 and 52. An impact may be applied and it may cause a failure.

When the return time of the actuators 50 and 52 deviates from the outward reference due to the mode of being less than the lower limit value, an impact due to the operation of the actuators 50 and 52 is applied to the loader 40 and the lead frame supply unit 42 as in the case of the outward time. Can cause a malfunction. If the outward path reference is deviated from the outward path reference (actuator operating time is too slow) due to the outward path time and the return path time of the actuators 50 and 52 exceeding the upper limit values, the lead frame 3 is pushed out and conveyed slowly, and the throughput of the resin molding apparatus 100 is reached. Decreases.

The second device stop processing procedure is a stop processing procedure for stopping the operation of the resin molding device 100 after the molded product 30 is carried out from the molding die 20 by the unloader 44. In the second device stop processing procedure, when the loader 40 is carrying the lead frame 3 and the resin 39 into the molding die 20, the lead frame 3 is molded and the molded product is molded before the operation of the resin molding device 100 is stopped. Carry out 30.

When the second device stop processing procedure is executed, the control unit 10 indicates that the execution of the second device stop processing procedure has started (an example of the execution content of the abnormal processing) as one of the displays of various output information on the touch panel 9. To display. The fact that the execution of the second device stop processing procedure has started is displayed as, for example, an “alarm display”.

In the second device stop processing procedure, when the lead frame 3 is being carried into the molding die 20, all the lead frames 3 being carried in are molded. Then, after all the molded products 30 have been stored in the out magazine 72, the operation of the resin molding apparatus 100 is stopped. In the second device stop processing procedure, the new lead frame 3 is not supplied (newly carried in) from the in-magazine 7. When the operation of the resin molding apparatus 100 is stopped, all the actuators are shifted to a predetermined stop state. The predetermined stopped state is the same as the stopped state of the actuator in the stopped state of the normal (normal) resin molding apparatus 100.

In the preset, the second device stop processing procedure is set to be selected and executed when the actuator 54 is identified as an abnormal actuator by the abnormality detecting unit 11. In the present embodiment, an actuator for carrying out the molded product 30 such as the actuator 54 is set to be selected and executed when the abnormality detection unit 11 identifies the actuator as an abnormality actuator.

Even if the actuator 54 is identified as an abnormal actuator, it does not immediately cause a risk of molding an inappropriate molded product 30, but eventually, a problem may occur in carrying out the molded product 30. For example, when the operating time of the actuator 54 exceeds the upper limit value and deviates from the reference range, the delivery of the molded product 30 is delayed, and the throughput of the resin molding apparatus 100 is lowered. If a problem occurs in carrying out the molded product 30, it is necessary to stop the resin molding apparatus 100 and maintain the actuator identified as the abnormal actuator. In particular, it is a problem that the resin molding apparatus 100 is forced to be stopped carelessly (suddenly or unplannedly). Therefore, when the actuator 54 is identified as an abnormal actuator in this way, the second device stop processing procedure is executed instead of the first device stop processing procedure. This enables preventive maintenance of the actuator identified as an abnormal actuator.

If the operating time of the actuator 54 is less than the lower limit and the reference range is exceeded, an impact due to the operation of the actuator 54 may be applied to the unloader 44, which may cause a failure.

In the second device stop processing procedure, since the molding of the lead frame 3 being carried in and the accommodation of the molded product 30 in the out magazine 72 are continued, the resin molding device is started from the start of the execution of the second device stop processing procedure. The time until the 100 is stopped is longer than the time from the start of execution of the first device stop processing procedure to the stop of the resin molding device 100. Therefore, when the actuator 54 is identified as an abnormal actuator, by executing the second device stop processing procedure instead of the first device stop processing procedure, the user can perform the abnormal actuator even before the resin molding device 100 is stopped. It is possible to start preparing for maintenance of the actuator identified as. The user can recognize the necessity of starting maintenance preparation by the alarm display displayed on the touch panel 9.

[Explanation of device stop processing]
Hereinafter, the flow of device stop processing will be described with reference to the flow charts of FIGS. 4 to 6.

FIG. 4 shows a flow chart of abnormal processing. When the control unit 10 issues an operation start command to the actuator (# 41), the timekeeping unit 12 starts measuring the operation time (# 42). When the timekeeping unit 12 measures and acquires the operating time of the actuator, the control unit 10 stores the operating time in the storage unit 8 and displays it on the touch panel 9 (# 43).

When the operating time of the actuator is stored in the storage unit 8, the abnormality detection unit 11 compares the operating time with the reference range corresponding to the actuator for which the operating time has been acquired, and the operating time is within the reference range. If there is (# 44, Yes), return to # 41. If the operating time is out of the reference range (# 44, No), the actuator is identified as an abnormal actuator and the actuator shifts to # 45.

If the actuator identified as the abnormal actuator is the target of the first device stop processing procedure (# 45, Yes), the control unit 10 starts and ends the first device stop processing procedure (# 46). If the actuator whose operating time is out of the reference range is not the target of the first device stop processing procedure (# 45, No), the control unit 10 starts and ends the second device stop processing procedure (# 47). .. If the actuator whose operating time is out of the reference range is not the target of the first device stop processing procedure (# 45, No), the control unit 10 further asks whether the actuator is the target of the second device stop processing procedure. It may be determined whether or not, and if it is the target of the second device stop processing procedure, it may be controlled to start the second device stop processing procedure (# 47).

FIG. 5 shows a flow chart of the first device stop processing procedure. When the first device stop processing procedure is started, the control unit 10 causes the touch panel 9 to display to that effect (error display) (# 51). Further, the control unit 10 stops the lead frame 3 (molding object) from being carried into the molding mold 20 by the lead frame supply unit 42 and the loader 40 (# 52).

Further, if the lead frame 3 (molding object) has already been carried into the molding die 20, the control unit 10 molds the lead frame 3 (object to be molded) as it is (# 53, Yes), and opens the molding die 20 after molding. The actuator identified as an abnormal actuator is shifted to a predetermined stop state (# 55). Then, the resin molding apparatus 100 is stopped (# 56).

If the lead frame 3 (molding object) has not been carried into the molding die 20 (# 53, No), the control unit 10 shifts the actuator identified as the abnormal actuator to a predetermined stop state (# 55). The resin molding apparatus 100 is stopped from (# 56).

FIG. 6 shows a flow chart of the second device stop processing procedure. When the second device stop processing procedure is started, the control unit 10 causes the touch panel 9 to display to that effect (alarm display) (# 61). Further, the control unit 10 stops new loading of the lead frame 3 from the in-magazine 7 (# 62).

The control unit 10 molds all the lead frames 3 being carried in (# 63), and takes out the molded product 30 from the mold 20 and stores it in the out magazine 72 (# 64). After that, the control unit 10 shifts all the actuators to a predetermined stop state, and then stops the resin molding apparatus 100 (# 56).

As described above, it is possible to provide a resin molding apparatus and a method for manufacturing a resin molded product that appropriately stop in response to an abnormality in the drive mechanism.

[Another Embodiment]
(1) In the above embodiment, the first device stop processing procedure is selected when an actuator for carrying in the lead frame 3, such as the actuator 52 or the actuator 50, is identified as an abnormal actuator by the abnormality detecting unit 11. I explained the case where it is set in the preset. However, when the first device stop processing procedure is selected, the present invention is not limited to the above mode.

The first device stop processing procedure may be set to be selected when either the actuator 52 or the actuator 50 is identified as an abnormal actuator by input from the touch panel 9 by the user. Further, the first device stop processing procedure may be selected when the first servomotor 56 of the transfer mechanism 46 or the actuator 54 of the unloader 44 is identified as an abnormal actuator.

(2) In the above embodiment, the second device stop processing procedure is preset so that the actuator for carrying out the molded product 30 such as the actuator 54 is selected when the abnormality detection unit 11 identifies the actuator as an abnormality actuator. The case where it is set was explained. However, when the second device stop processing procedure is selected, the present invention is not limited to the above mode.

The second device stop processing procedure may be set to be selected when the actuator 52 or the actuator 50 is identified as an abnormal actuator by input from the touch panel 9 by the user.

(3) In the above embodiment, in the first apparatus stop processing procedure, if the lead frame 3 is being molded in the molding die 20, after the lead frame 3 being molded is molded, the molded product 30 is molded. An example of a stop processing procedure for stopping the operation of the resin molding apparatus 100 without carrying it out from the mold 20 has been described. However, the procedure for stopping the first apparatus is not limited to the case where the operation of the resin molding apparatus 100 is stopped without carrying out the molded product 30 from the molding die 20.

In the first device stop processing procedure, the lead frame 3 and the resin 39 are stopped (prohibited) from being carried into the molding die 20 by the lead frame supply unit 42 and the loader 40, and the lead frame 3 is molded in the molding die 20. If it is in the middle of the process, it may be a stop processing procedure for stopping the operation of the resin molding apparatus 100 after molding the lead frame 3 during molding. For example, in the first device stop processing procedure, if the lead frame 3 is being molded in the molding die 20, the lead frame 3 being molded is carried out after molding, and the operation of the resin molding device 100 is performed after the carrying out. It may be a stop processing procedure for stopping.

(4) In the above embodiment, the case where each actuator is an air cylinder 500 has been described. However, as the actuator, an oil cylinder, a servomotor, an electromagnetic solenoid, or a combination of a reciprocating cam mechanism and a motor can also be used.

(5) In the above embodiment, the abnormality detection unit 11 has described a case where an actuator whose outward trip time or return trip time is out of the reference range is specified as an abnormal actuator. However, the abnormality detection unit 11 may specify an actuator in which only one of the outward trip time and the return trip time is out of the reference range as an abnormal actuator. That is, the abnormality detection unit 11 may specify only the actuator whose outward trip time is out of the reference range as the abnormality actuator. Alternatively, the abnormality detection unit 11 may specify only the actuator whose return time is out of the reference range as the abnormality actuator.

(6) In the above embodiment, the abnormality detection unit 11 has described a case where an actuator whose operating time is out of the reference range is specified as an abnormality actuator. Outside the reference range in this case is when the operating time is less than the lower limit value or exceeds the upper limit value in the reference range. However, the abnormality detection unit 11 may specify only the actuator whose operating time is less than the lower limit value as the abnormality actuator. As described above, by specifying only the actuator in which the abnormality that the operation time is too fast occurs as the abnormal actuator, it is possible to prevent the manufacture of the improper molded product 30.

(7) In the above embodiment, the operation time of the outward route is the time from the time when the control unit 10 commands the actuator to move forward to the time when the second sensor Sb detects the proximity of the detected unit Ls. Illustrated and explained. However, as the operation time of the outward path, the time until the piston rod L moves from the last retracted position La to the most advanced position Lb may be adopted. In this case, the time counting start reference of the operation time is set when the first sensor Sa no longer detects the proximity of the detected portion Ls.

(8) In the above embodiment, the operation time of the return path is the time from the time when the control unit 10 commands the actuator to move backward to the time when the first sensor Sa detects the proximity of the detected unit Ls. Illustrated and explained. However, as the operation time of the return path, the time until the piston rod L moves from the most advanced position Lb to the last retracted position La may be adopted. In this case, the time counting start reference of the operation time is set when the second sensor Sb no longer detects the proximity of the detected portion Ls.

(9) In the above embodiment, the case where the resin molding apparatus 100 uses the molding die 20 to resin-mold the lead frame 3 with the resin 39 has been described. However, what can be a molding object of the resin molding apparatus 100 is not limited to the lead frame 3. The resin molding apparatus 100 may use a metal substrate, a resin substrate, a glass substrate, a wiring substrate, a semiconductor substrate, and other substrates as objects to be molded.

(10) In the above embodiment, in the molding mechanism 2, the resin 39 is melted by the molding die 20 which has been preheated by the heater 24 in a state where the lead frame 3 is housed in the molding die 20, and then the resin 39 is melted from the pot 23a by the plunger 23. An example of a so-called transfer molding method in which the resin 39 is extruded and supplied to the cavity 21b and the lead frame 3 is molded by the resin 39 has been described as an example. However, the molding mechanism 2 is not limited to the transfer molding method. For example, the molding mechanism 2 may perform a compression molding method. In the compression molding method, for example, the molding mechanism 2 directly supplies a liquid or granular resin to the cavity 21b of the molding die 20, and after the resin is melted, the lead frame 3 or the like is melted. This is a resin molding method in which a resin is dipped in a resin to be molded.

(11) In the above embodiment, the control unit 10 starts the second device stop processing procedure unless the actuator whose operating time is out of the reference range is the target of the first device stop processing procedure (# 45, No). (# 47) The case of terminating is illustrated and described. However, the starting order of the first device stop processing procedure and the second device stop processing procedure is not limited to this. For example, instead of determining the first device stop processing procedure in # 45, the control unit 10 may determine whether or not the actuator whose operating time is out of the reference range is subject to the second device stop processing procedure. .. In this case, if it is the target of the second device stop processing procedure, the second device stop processing procedure is executed. If it is not the target of the second device stop processing procedure, the first device stop processing procedure is executed. If it is not the target of the second device stop processing procedure, the control unit 10 further determines whether or not the actuator is the target of the first device stop processing procedure, and if it is the target of the first device stop processing procedure. It may be controlled to start the first apparatus stop processing procedure.

The configuration disclosed in the above embodiment (including another embodiment, the same shall apply hereinafter) can be applied in combination with the configuration disclosed in other embodiments as long as there is no contradiction. The embodiments disclosed in the present specification are examples, and the embodiments of the present invention are not limited thereto, and can be appropriately modified without departing from the object of the present invention.
