Description

TECHNICAL FIELD The present specification relates to a component mounting machine having a component supply device for setting up a component holder.

2. Description of the Related Art A technology for mass-producing substrate products by carrying out work on a substrate on which a circuit pattern is formed has become widespread. 2. Description of the Related Art A component mounting machine that performs a component mounting operation as a board-related operation generally includes a component supply device that supplies components using a component holder. There is a type of component supply apparatus that performs a setup process before starting to use the component holder, and for example, this corresponds to an apparatus that supplies components manufactured by cutting a semiconductor wafer. Japanese Patent Application Laid-Open No. 2002-300001 discloses a technical example related to a component supply device that performs a setup process.

The parts management system of Patent Literature 1 includes identification means attached to each of a plurality of part holders (part plates), reading means for reading the identification means of the part holders pulled out from slots in the magazine, and read identification means. and determination means for determining whether the component holder is correct or wrong based on the information of the means. This parts management system performs a setup process for judging whether all the parts holders in the magazine are correct or not at the start of operation. Furthermore, the parts management system performs setup processing even after the start of operation, for example, on the condition that the opening/closing door provided in the magazine is opened or closed. According to this, it is said that there is no need to make a correct/incorrect judgment each time the component holder is pulled out, and the judgment processing time can be shortened.

JP 2016-139712 A

By the way, in the technical example of Patent Literature 1, all the component holders in the magazine are pulled out and returned in order, and after confirming that all the component holders are correct, the component mounting work is started. . According to this, it is possible to avoid a situation where an error in the component holder is found after the mounting work is started and the mounting work is interrupted. However, with this technique, the start of the mounting work is delayed, so the production efficiency is reduced by the amount of the delay. This problem is not limited to a component supply device that supplies wafer components manufactured from a semiconductor wafer, but may also occur in a component supply device that uses a tray as a component holder.

An object of the present specification is to provide a component mounting machine with improved production efficiency compared to the conventional one by streamlining the implementation timing of component holder setup processing performed by a component supply device.

In the present specification, a substrate transport device for loading, positioning, and carrying out a substrate, and a plurality of component holders each holding a component are stored in a magazine, and any one of the component holders is selectively placed at a component supply position. a component supply device that draws out the components from the above to supply the components, a component transfer device that picks up the components at the component supply position using a component mounting tool and mounts the components on the positioned substrate, and the substrate transport and a control device for controlling operations of the device, the component supply device, and the component transfer device. In addition to starting the operation control of the component transfer device, the setup process has been performed in the time zone after receiving the instruction to start the work, which is the operation time zone in which the component supply device requires the supply of the component. The part holder is pulled out to the part supply position and is controlled to supply the part, and it is a time period after receiving the instruction to start the work, and the supply of the part is not required in the part supply device. Disclosed is a component mounting machine that is controlled to pull out the component holder to the component supply position and perform the setup process before the start of use during a standby period.

In the component mounting machine disclosed in the present specification, the control device starts controlling the operation of the substrate conveying device, the component supply device, and the component transfer device according to the instruction to start the work, advances the mounting work, and starts the component supply device. Control is performed so that the components are supplied during the operation time zone, and the setup processing of the component holder is executed during the standby time zone of the component supply device. According to this, the set-up processing for the minimum required number of the plurality of component holders is performed before the mounting work is started, but the rest of the set-up processing is performed during the waiting time period that occurs between the mounting work. . Therefore, the delay in starting the mounting work is suppressed, and the standby time period is effectively used for the execution of the setup process, thereby improving the production efficiency as compared with the conventional art.

2. Configuration of Control of Component Mounting Machine 1 of Embodiment Next, the configuration of control of the component mounting machine 1 of the embodiment will be described. The control device 6 is configured using a computer device. The control device 6 controls the operations of the substrate transport device 2, the component supply device 3, the component transfer device 4, and the component camera device 5 based on the mounting job data. Mounting job data is data describing details of mounting work for each type of substrate product to be produced. The mounting job data includes, in addition to information about the board K, information on the types of parts P to be mounted, the order of mounting on the board K, the number of mounting points, and the mounting coordinate position, and information on each device (2, 3, 4, 5). including information on the operating conditions of

When receiving the instruction to start work, the control device 6 starts controlling the operation of each device (2, 3, 4, 5) and advances the mounting work of the component P. As shown in FIG. An instruction to start work is given by an input operation to an input unit (not shown), an operation of an operation switch, a remote instruction from a portable terminal, or the like. The control device 6 performs control in cooperation with the subordinate device control units (39, etc.) of each device (2, 3, 4, 5). The control device 6 may include part of the functions of a lower device control section (39, etc.).

The control device 6 has four functional units related to control of the component supply device 3, namely, an order determination unit 61, a time period determination unit 62, a setup control unit 63, and a component supply control unit 64. The order determination unit 61 determines the order in which a plurality of component types of the component P are mounted on the board K, the number of mounting points for each component type per board K, and the component type of the component P held by each component holder 32. Based on this, the order of use of the plurality of component holders 32 is determined in advance. The function of the order determination unit 61 will be described in detail in later examples.

After receiving an instruction to start work, the time zone determination unit 62 determines whether it is an operating time zone that requires the supply of the parts P in the component supply device 3 or a standby time zone that does not require the supply of the parts P. . The time period determination unit 62 determines the time period during which the board transfer apparatus 2 waits for the board K to be carried in from the previous process, and the time period during which the board K on which the component P has been mounted is waiting for the board K to be carried out to the subsequent process. The zone is determined as the waiting time zone.

For example, it is assumed that the solder printing inspection apparatus in the previous process has not completed the inspection work of the board K and the board K cannot be unloaded. The state in which the substrate K cannot be carried out is transmitted from the control device of the solder print inspection device to the control device 6 of the component mounting machine 1 . Therefore, the time zone determination unit 62 can determine that it is a standby time zone in which the board K is waiting for the carry-in. On the other hand, when the solder printing inspection apparatus is ready to unload the inspected board K, the board K is immediately transported to the mounting position by the board conveying apparatus 2 or can be transported. Therefore, the time period determination unit 62 determines that it is an operation time period in which the part P needs to be supplied.

Furthermore, it is assumed that the board inspection apparatus in the post-process has not completed the inspection work of the board K and the next board K cannot be carried in. A state in which the next board K cannot be carried in is transmitted from the control device of the board inspection apparatus to the control device 6 of the component mounting machine 1 . Therefore, the time zone determination unit 62 can determine that it is a waiting time zone in which the substrate K is waiting for unloading to the post-process. In the case of the component supply device 3 that performs automatic calibration processing, automatic maintenance processing, and the like, the time period determination unit 62 determines an inoperable time period that does not belong to either the operating time period or the standby time period. The inoperable time zone is a time zone during which automatic calibration processing, automatic maintenance processing, etc. are being performed, and neither setup processing nor component supply operation is being performed.

The setup control unit 63 controls the component supply device 3 so as to perform setup processing before the component holder 32 is started to be used. The contents and processing flow of the setup process will be described in detail below. At step T1 in FIG. 3, the pullout mechanism 33 of the component supply device 3 pulls out the component holder 32 from the magazine 37 to the component supply position. In the next step T2, the wafer imaging camera 365 takes an image of the identification code attached to the holding plate 321 of the component holder 32, and confirms the component type of the component P (setup processing). If the part type is incorrect, the operator is notified of this fact.

In the next step T3, the wafer imaging camera 365 images the parts P and the reference parts from above, and performs confirmation processing (setup processing) of the arrangement status of the plurality of parts P. FIG. In the next step T4, the contact-type height sensor 361 measures the height position of the expanding table 322 of the component holder 32, and confirms the height position of the component P (setup processing). The confirmed arrangement status and height position of the component P are reflected in the control of the suction operation of the component P by the suction nozzle 43 (see step Q3 in FIG. 4).

At the next step T5, the drawer mechanism 33 returns the component holder 32 to the magazine 37. FIG. This completes the setup process. Note that the setup processing may include processing contents other than those described above. For example, confirmation processing regarding posture abnormalities such as reversing the part P back and forth and rotating it by 90° is also included in the category of the setup processing.

The setup process is performed when the operation time period comes immediately after the start of the operation control and there is no component holder 32 for which the setup process has been performed. At this time, setup processing for the minimum number of component holders 32 necessary for the time being is performed. Also, the setup process is performed for the required component holders 32 even when the mounting work based on the mounting job data is progressing and there is no component holder 32 for which the setup process has been performed during the operation time period. be done. In these cases, the mounting work is in a waiting state while the setup process is being performed.

Furthermore, the setup process is performed in accordance with the order of use of the component holders 32 determined by the order determination unit 61 by effectively utilizing the standby time zone of the component supply device 3 . In this case, the time during which the setup process is performed does not affect the progress of the mounting work. That is, in the present embodiment, only the setup processing of some of the component holders 32 causes the mounting work to wait.

In contrast, in the prior art, the setup process for all component holders 32 waits for the mounting operation. Therefore, according to the present embodiment, it is possible to shorten the time required for production by the amount of time required for the setup processing that is effectively used during the standby time period. Even if the loading and unloading of substrates K are smoothly carried out and there is no waiting period, the time required for production will be less than or equal to that of the prior art.

The component supply control unit 64 controls the component supply device 3 so as to supply the component P during the operation time period of the component supply device 3 . The operation flow of the supply operation of the component P will be described in detail below. At step Q1 in FIG. 4, the pullout mechanism 33 of the component supply device 3 pulls out the component holder 32 from the magazine 37 to the component supply position. In the next step Q2, the push-up pot 34 and the push-up pin 35 push up the designated part P. In the next step Q3, the suction nozzle 43 of the component transfer device 4 sucks the component P pushed up. Note that in a configuration in which a plurality of suction nozzles 43 are provided on the mounting head 42, a plurality of components P are picked up in order. At the next step Q4, the drawer mechanism 33 returns the component holder 32 to the magazine 37. FIG. As a result, the operation of supplying the component P is completed.

In this embodiment, the parts P may be supplied following the setup process of the part holder 32 . In this case, the control of the control device 6 jumps from step T4 in FIG. 3 to step Q2 in FIG. According to this, step T5 in FIG. 3 and step Q1 in FIG. 4, in other words, the trouble of returning the component holder 32 and pulling it out again can be omitted, and the production efficiency can be improved.

3. Operation of Component Mounting Machine 1 of Embodiment Next, the operation of the component mounting machine 1 of the embodiment will be described with reference to the control flow of FIG. 5 and the example of FIG. In step S1 of FIG. 5, the control device 6 acquires mounting job data. The mounting job data is, for example, transmitted from a host computer or set by an operator. The mounting job data includes information on the name of the component holder 32 to be used, the type and number of components P held by each component holder 32, and the order and number of components to be mounted on the substrate K for each type of component. there is

In the example of FIG. 6, the seven component holders 32 are named TA1-TA3 and TB1-TB4. The three component holders 32 with the names TA1 to TA3 hold a total of 150 parts of the component type A each, and the four component holders 32 with the names TB1 to TB4 hold a total of 200 parts of the component type B. holding each. The operator refers to the mounting job data to set the component holders 32 with names TA1 to TA3 in slots No. 1 to No. 3 of the magazine 37, respectively, and sets the component holders 32 with names TB1 to TB4 in slot No. 4. Set each to No.7. Note that slots No. 8 to No. 10 are unused. Further, since the correspondence between the names of the component holders 32 and the slot numbers is stored in the control device 6, there is no problem even if the set positions are other than those described above.

Next, the mounting order on the board K is set so that the component type A is mounted later and the component type B is mounted first. The number of mounting points per board K is determined to be 10 pieces for the component type A and 20 pieces for the component type B. Therefore, each of the component holders 32 with the names TA1 to TA3 supplies the components P to 15 boards K (=150/10 in total), and each of the component holders 32 with the names TB1 to TB4 supplies 10 boards ( = 200 pieces/20 pieces) of parts P are supplied to the substrates K. Note that the order in which the component holders 32 are used in the same component type is not limited. Here, as for the order of use of the component holders 32, those with smaller slot numbers have priority.

In the next step S2, the order determining section 61 of the control device 6 determines in advance the order of use of the plurality of component holders 32 before starting the motion control. Specifically, the order determining unit 61 determines the order of use of the component holder 32 with the name TB1 of the slot No. 4, which has the smallest number among the slots No. 4 to 7 that supply the component type B whose mounting order is first. Decide first. Then, the component holder 32 with the name TB1 corresponds to the 1st to 10th boards K. As shown in FIG. In addition, the order determination unit 61 sets the use order of the component holder 32 having the name TA1 of the slot No. 1 with the smallest number among the slots No. 1 to 3 that supply the component type A whose mounting order is the second. to decide. Then, the component holder 32 with the name TA1 corresponds to the 1st to 15th substrates K. As shown in FIG.

According to the above determination, there is no part P of the part type B for the 11th board K. Therefore, the order determination unit 61 determines the use order of the component holder 32 with the name TB2 in the slot No. 5 to be the third. Next, the component P of the component type A disappears from the 16th board K. Therefore, the order determination unit 61 determines the order of use of the component holder 32 with the name TA2 in the slot No. 2 as fourth. Next, the part P of the part type B disappears from the 21st board K. Therefore, the order determination unit 61 determines the use order of the component holder 32 with the name TB3 in the slot No. 6 as fifth.

Furthermore, the parts P of both the part type A and the part type B for the 31st board K are eliminated. Therefore, the order determination unit 61 determines the use order of the component holder 32 with the name TB4 of the slot No. 7 to which the component type B having the first mounting order is supplied is No. 6. Further, the order determination unit 61 determines seventh as the use order of the component holder 32 with the name TA3 of the slot No. 3 that supplies the component type A later in the mounting order. If there are three or more types of parts, the consumption of parts P as the mounting work progresses becomes more complicated than described above. Still, the order determination unit 61 can simulate the consumption progress of the parts P and determine the order of use of the part holders 32 .

In the next step S3, the control device 6 receives an instruction to start work and starts controlling the operation of each device (2, 3, 4, 5). In the next step S4, the time zone determination section 62 determines whether the component supply device 3 is in the operating time zone or in the standby time zone. In step S5 when it is determined that it is the waiting time period, the setup control section 63 controls the component supply device 3 so as to perform the setup process. In the initial step S5, the setup process of the component holder 32 is started. After the predetermined control cycle time has elapsed, execution of the control flow is returned to step S4.

When it is determined to be in the standby time period in step S4 for the second time or later, the setup process is continued in step S5 for the second time or later. Alternatively, when the setup process for a certain component holder 32 ends, the setup process for the next component holder 32 is started. The setup process in step S<b>5 is performed according to the order of use of the component holders 32 determined by the order determination unit 61 .

In step S11 when it is determined that it is the operating time period in step S4, the control device 6 determines whether there is a component holder 32 that holds the component P of the component type to be mounted from now on and that can be used immediately. Investigate whether there is The ready-to-use component holder 32 means a component holder 32 that has undergone set-up processing and has not yet been used or that has one or more components P left in it during use. In step S12 when there is no component holder 32 that can be used immediately, the setup control section 63 causes the setup processing of the component holder 32 corresponding to the type of component to be mounted from now on to be performed up to step T4 in FIG. In the next step S13, the component supply control unit 64 starts the control from step Q2 in FIG. 4 to cause the component P to be supplied.

In step S14 when there is a ready-to-use component holder 32 in step S11, the control device 6 investigates whether or not the component supply device 3 is in the process of setting up. The state in which the setup process is in progress means a state in which the component holder 32 is pulled out to the component supply position, or a state in which the component holder 32 is being transported to the component supply position. When the component holder 32 is in the process of being returned from the component supply position to the magazine 37, the control device 6 terminates the return and determines that the setup process is not in the process of being performed. If the setup process is not in progress, execution of the control flow proceeds to step S13. In step S13, the component supply control unit 64 executes the control of the operation flow shown in FIG. 4 to cause the component P supply operation to be performed.

If the setup process is in progress in step S14, execution of the control flow proceeds to step S15. In step S15, the control device 6 determines whether or not a termination condition for completing the setup process in progress is satisfied. The termination condition is that another component holder 32 that holds the component P of the same component type as the component holder 32 that is in the middle of the setup process and that is earlier in the order of use is yet to be used.

In step S16 when the termination condition is satisfied, the setup control section 63 executes termination processing. That is, the setup control section 63 terminates the setup process during the execution of the component holder 32 whose use order is late, up to step T4 in FIG. 3, and changes the use order. If there is only one other component holder 32 earlier in the order of use, the order of use is switched with the component holder 32 later in the order of use. When there are two or more separate component holders 32 with the earliest order of use, the component holder 32 with the lowest order of use is changed to the earliest order of use, and the order of use of the other two component holders 32 is moved down. . After step S16, execution of the control flow proceeds to step S13. In step S13, the component supply control unit 64 starts control from step Q2 in FIG. 4 to cause the component P to be supplied.

In step S17 when the end condition is not satisfied, the setup control section 63 executes the interruption process. That is, the setup control section 63 interrupts the setup processing of the component holder 32 that is used later and returns the component holder 32 to the magazine 37 . After step S17, execution of the control flow proceeds to step S13. In step S13, the component supply control unit 64 executes the control of the operation flow shown in FIG. 4 to cause the component P supply operation to be performed. After step S13, execution of the control flow returns to step S4.

Here, another component holder 32 that is used earlier in the order of use has, of course, already undergone the setup process, but it may be before the start of use, during use, or at the end of use. Before the start of use, the end condition is satisfied, and the setup process in progress is ended, and the order of use is changed. As a result, it is possible to omit the trouble of returning the component holder 32 later in the order of use to the magazine 37 and pulling out the component holder 32 earlier in the order of use, thereby improving the production efficiency.

Then, when another component holder 32 earlier in the order of use is in use, the setup processing of the component holder 32 later in the order of use is interrupted and returned, and the component holder 32 earlier in the order of use is pulled out and used. P supply operation is performed. This is advantageous in terms of inventory control and quality control, since a plurality of in-use component holders 32 that hold components P of the same component type are not required. Moreover, priority is given to the supply of parts P that are required at the present time, and non-urgent setup processing is postponed to the future standby time zone, so that overall production efficiency is improved. Note that if another component holder 32 earlier in the order of use has already been used, it is not referred to for determining the termination condition.

4. Implementation Timing of Setup Processing in Examples Next, two cases will be exemplified for the implementation timing of the setup processing of the component holder 32 in the example of FIG. 6 . In the first case, when the operation control is started in step S3, the first board K can be loaded, and the component supply device 3 is in the operation time zone. Therefore, execution of the control flow proceeds from step S4 to step S11. At this point, there is no component holder 32 that holds the component P of the component type B and has undergone the setup process, so execution of the control flow proceeds to step S12. Then, the setup processing of the component holder 32 with the name TB1 is performed, and 20 components P of the component type B are supplied to the first board K in the next step S13.

After this, execution of the control flow returns from step S4 to step S11. At this point, there is no component holder 32 that holds the component P of the component type A and has undergone the setup process, so execution of the control flow proceeds to step S12. Then, the setup processing of the component holder 32 with the name TA1 is performed, and ten components P of the component type A are supplied to the first board K in the next step S13.

Thereafter, in parallel with the operation of unloading the first substrate K and loading the second substrate K, the execution of the control flow returns from step S4 to step S13 via steps S11 and S14. . As a result, 20 parts P of the part type B are supplied to the second board K. Furthermore, in the next step S13, 10 parts P of the part type A are supplied to the second board K. Similarly, 20 parts P of the part type B and 10 parts P of the part type A are supplied to the third and subsequent boards K as well.

However, after the parts P of the part type B and the part type A were supplied to the sixth board K, the seventh board K became unable to be carried in, and the component supply apparatus 3 shifted to the standby period. At this time, execution of the control flow proceeds from step S4 to step S5. Steps S4 and S5 are repeated during the waiting period. Then, the setup process is performed in the order of the component holders 32 named TB2, TA2, TB3, TB4, and TA3 according to the order of use.

After that, in the middle of the setup processing of the component holder 32 with the name TA3, it became possible to carry in the seventh board K, and the component supply device 3 shifted to the operating time zone. At this time, execution of the control flow proceeds from step S4 to step S15 via steps S11 and S14. In step S15, the component holder 32 with the name TA1, which holds the component P of the same component type A as the component holder 32 with the name TA3, which is in the middle of the setup process, is in the middle of being used. That is, the end condition is not satisfied. Therefore, in step S17, the setup process for the component holder 32 with the name TA3 is interrupted. In the next step S13, 20 parts P of the part type B are supplied to the seventh board K. As shown in FIG.

After that, the loading and unloading of the board K is carried out smoothly, and the waiting time zone of the component supply device 3 does not occur. Therefore, by repeating steps S4, S11, S14, and S13, the parts P are smoothly supplied to the 7th to 30th substrates K. FIG. Then, the component P of the component type B can be supplied to the 31st board K. However, there is no component holder 32 that can hold the component P of the component type A and can be used immediately, and the execution of the control flow advances from step S11 to step S12. Here, the setup process for the component holder 32 with the name TA3 is performed, and 10 components P of the component type A are supplied to the 31st board K in the next step S13.

Next, in the second case, when the operation control of step S3 is started, the first substrate K cannot be loaded, and the component supply device 3 is in the standby time period. Therefore, steps S4 and S5 of the control flow are repeated. At this time, the setup process is performed in the order of the component holders 32 named TB1, TA1, and TB2 according to the order of use.

Then, in the middle of the setup processing of the component holder 32 with the name TB2, the first board K became ready to be loaded, and the component supply device 3 shifted to the operating time period. At this time, execution of the control flow proceeds from step S4 to step S15 via steps S11 and S14. In step S15, the component holder 32 with the name TB1 that holds the component P of the same component type B as the component holder 32 with the name TB2 that is in the middle of the setup process has not yet been used. That is, the termination condition is satisfied.

Therefore, in step S16, setup processing for the component holder 32 with the name TB2 is performed up to step T4 in FIG. Further, the order of use of the component holder 32 with the name TB2 is changed to No. 1, and the order of use of the component holder 32 with the name TB1 is changed to No. 3. In the next step S13, 20 parts P of the part type B are supplied to the first board K from the part holder 32 with the name TB2.

In the component mounting machine 1 of the embodiment, the control device 6 starts controlling the operation of the board conveying device 2, the component supply device 3, and the component transfer device 4 according to the instruction to start the work, advances the mounting work, and supplies the component. Control is performed so that the parts P are supplied during the operation time of the device 3, and the setup processing of the component holder 32 is performed during the standby time of the component supply device 3. According to this, the set-up processing for the minimum required number of the plurality of component holders 32 is performed before the mounting work is started, but the rest of the set-up processing is performed during the waiting time period that occurs between the mounting work. be. Therefore, the delay in starting the mounting work is suppressed, and the standby time period is effectively used for the execution of the setup process, thereby improving the production efficiency as compared with the conventional art.

5. Applications and Modifications of the Embodiments The contact-type height sensor 361 of the component supply device 3 can be provided inside the magazine 37 by adopting another detection method. In this mode, the setup process of step T4 in FIG. 3 is omitted. Alternatively, the wafer imaging camera 365 of the component supply device 3 may be omitted, and a code reader for reading the identification code of the holding plate 321 may be provided near the outlet of the housing 31 . In this aspect, step T2 of FIG. 3 is performed by the code reader and step T3 is performed by the substrate camera 44 of the mounting head 42. Also, the three steps T2 to T4 corresponding to the setup process may be simplified to only one step or two steps.

Also, although the order determining unit 61 can be omitted, the execution order of the setup processing of the component holders 32 during the standby time period is not optimized. For this reason, the number of cases where there is no component holder 32 for which the setup process has been completed tends to increase during the operation time period, and the effect of improving the production efficiency tends to decrease. Further, instead of steps S15 to S17 in FIG. 5, simplification is possible by always performing the interruption process of step S17. Further, the component supply device 3 may be of a type that uses a tray as the component holder 32 . Various other applications and modifications are possible for the embodiments.
