Description

  The present invention relates to a component mounting system that produces a plurality of types of substrates by a component mounter that mounts components on a substrate.

  Conventionally, a component mounting machine (mounter) is used to suck an electronic component supplied from a component supply device (feeder) with a suction head, and the suction head is moved to a predetermined position on the substrate to mount the component on the substrate. To be done. In this case, board production (component mounting) is performed by creating a production program for producing the board for each board type. Each production program includes various data for producing a board on a mounting machine, for example, data about a board, data about a mounting position, data about a part (for example, height and width dimensions), data about a suction position, image recognition, etc. Information, data on application of adhesive, and the like.

  When producing multiple types of boards, the parts to be mounted differ for each production program, so the types of feeders that supply these parts are also different, and preparation work such as feeder replacement and rearrangement is required. . Therefore, in order to efficiently execute a plurality of production programs in the shortest time, the plurality of production programs are made as if they were one program (clustered). Optimization of production programs or feeder arrangement is performed so that feeder rearrangement is not required even if it changes (Patent Document 1).

  With this clustering, even when the type of substrate to be produced is switched, rearrangement of feeders is not necessary, so that the setup change time can be greatly shortened.

In addition, if a component supply device such as a feeder is not mounted at the correct position, the correct component cannot be mounted on the board. Therefore, the component is mounted after detecting whether the feeder is mounted at a proper position (Patent Literature). 2, 3).

  However, conventionally, it is necessary to confirm the component mounting state again for a component supply device that does not match the component supply device arrangement data of the board read immediately before, and shortening the setup change time has been limited.

  The present invention has been made to solve such problems, and an object of the present invention is to provide a component mounting system capable of efficiently producing a wide variety of boards.

The present invention
A component mounting system for mounting a component on a board to produce the board,
A component supply device for supplying components to be mounted on a substrate;
A component mounter for mounting a component supplied from a component supply device on a predetermined position of the board;
When producing multiple boards, if the placement of the component feeder in the component mounter is the same even if the boards are switched, it is checked whether the component feeder is mounted at a predetermined position on the component mounter. Matching means;
In the case where the component supply device is mounted at a predetermined position of the component mounter, it has a storage means for storing the verification result in association with each board information or information characterizing the production of the board,
At the time of board production in which the arrangement of the component supply devices is the same, the components are mounted on the board with reference to the verification result when the boards are switched.

  According to the present invention, when producing a plurality of boards, if the arrangement of the component supply apparatus in the component mounting machine is the same even if the boards are switched, the component supply apparatus is mounted at the regular position of the component mounting machine. If the component is mounted on a board that has the same layout of the component supply device and multiple boards are produced, the type of board to be produced There is no need to check the mounting state of the component supply device each time the operation is switched, and the effect that the production of various types of boards can be performed efficiently is obtained.

  Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

  FIG. 1 illustrates a system configuration in which the component mounter 1 is connected to the host computer 30 and components are mounted on the substrate 5.

  Under the control of the control unit 4, the component mounter 1 sucks an electronic component (hereinafter simply referred to as a component) supplied from the component supply device 20 with the suction head 2, and this suction head 2 is placed at a predetermined position on the substrate 5. And the component is mounted on the substrate 5. In this case, board production (component mounting) is performed by creating a production program for producing the board for each board type. Each production program includes various data for producing the substrate 5 on the component mounter 1, and includes, for example, data relating to the substrate, data relating to the mounting position, data relating to the component (for example, dimensions of height and width), and data relating to the suction position. , Information for image recognition, data relating to adhesive application, and the like. The production program is normally created by the host computer 30, transmitted to the component mounter 1, and stored in the data storage unit 3 of the component mounter 1.

  The component supply device 20 includes a component cassette 21 that stores supply components, and the component cassette 21 is provided with a barcode 22 that identifies the stored components. When the component supply device 20 is mounted on the component mounter 1, the host computer 30 has a barcode reader 31 as barcode reading means, and the barcode reader 31 is mounted on the component supply device 20. The barcode 22 attached to the component cassette 21 is read, and the host computer 30 obtains the lane number from the barcode 22 attached to the lane 6 of the component mounter 1, which component supply device 20 is Whether it is attached to the lane 6 is detected. Since a large number of component supply devices 20 are mounted on the component mounter 1, the correspondence between the component cassette 21 mounted on each component supply device 20 and the lane number is detected, and the corresponding relationship is detected by the host computer 30. It can be stored in the storage device 32.

  FIG. 2 shows a detailed configuration of the component mounting machine 1. The control unit 4 of the component mounter 1 includes a CPU 4a that controls the entire component mounting, a ROM 4c that stores various control programs and data, and a RAM 4b that stores control data and processing data and provides a work area. Data transmission / reception between the component mounter 1 and the host computer 30 is performed via the data transmission / reception unit 14. The production program transmitted from the host computer 30 is received via the data transmission / reception unit 14 and stored in the data storage unit 3. The control unit 4 drives the X / Y drive unit and other drive units 10 in accordance with the production program and the data input via the data input unit 13 to move the suction head 2 to the component supply device 20. The parts supplied from the above are sucked by the suction head 2. The sucked parts are recognized by the image recognition unit 11 provided with the camera 12 and their positions are corrected. Then, the picked parts are moved to a predetermined portion of the substrate 5 to be transported along the transport path and mounted on the substrate. Is done. The host computer 30 stores the correspondence between the component cassette 21 having the barcode read by the barcode reader 31 and the lane number in which the component supply device 20 to which the component cassette 21 of s is mounted is installed in the storage device 32. To remember.

  In such a configuration, when components are mounted on a substrate, the same types of components are often mounted regardless of the type of substrate, and there are often only a few types of components that differ on each substrate. For example, as shown in FIGS. 3A, 3B, and 3C, in the board (1), components A, B, C, D, E, F, G, H and j, p, q, v However, parts A, B, C, D, E, F, G, and H and k, n, r, and u are in the board (2), and parts A, B, C, D, and E are in the board (3). , F, G, H and l, m, s, t are mounted, and parts A, B, C, D, E, F, G, H are common to all the boards. In FIG. 3, the component supply device 20 storing each component is arranged as a front feeder bank 24 and a rear feeder bank 25 so as to face the front side (front side) and the back side (rear side) of the board. A configuration is shown.

  When such board production is performed continuously, parts common to each board are arranged at the same position, and different parts are arranged at positions where competition does not occur, so that the setup is changed when the board type is switched. You can eliminate the need.

  For example, the parts A, B, C, D, E, F, G, H common to the substrates (1), (2), (3) and the other parts j, p, q, v, k, n , R, u, and by adjusting the mounting position of the parts j, p, q, v, k, n, r, u which are not common, as shown in FIG. If it is determined, it is possible to prevent the mounting position of the component supply device 20 from changing even when the board (1), (2), or (3) is switched. Can be eliminated.

  However, in the conventional component erroneous mounting prevention system, since the mounting state of the component (component supply device) is collated based on the component supply device arrangement information for each board type, each component supply device is changed every time the board type is switched. It was necessary to check whether 20 was installed in the proper position. Even if the comparison of the part type and the part type used on the immediately preceding board is omitted and the verification of the same part is omitted, the verification of whether or not the part supply apparatus 20 that supplies the part is mounted at the correct position Was necessary.

  Therefore, component supply device arrangement information common to a plurality of production programs is created, and the mounting state of the component supply device 20 is checked against this data. For example, the component supply device arrangement information as shown in FIG. 5 is created as data 40 for the arrangement of the component supply device 20 in FIG. 4 and is stored in the storage device 32. Then, when the board is produced, instead of referring to the production program for producing the board, the data 40 is used to collate whether or not the component supply device 20 is correctly mounted (arranged) to produce the board.

  The data 40 shown in FIG. 5 includes information that can specify the production program used for creation, for example, the production program (1), (2) that characterizes the production of the board (1), (2), (3) or the board. ), (3) itself is included, and a verification result (OK) as to whether or not the component supply device 20 that supplies the components q to p is correctly mounted in each lane (1) to (20) of the component mounter is displayed. To be recorded. The host computer 30 is used for this verification. When a certain component supply device 20 is mounted on the component mounter 1, the host computer 30 determines which lane 6 is mounted and the barcode attached to the component cassette 21 mounted on the component supply device 20. 22 is read by the bar code reader 31, and when the component supply device 20 is at a predetermined position (regular position) of the component mounter 1, "OK" information is recorded. The created data 40 can be transmitted to the component mounter 1 and stored in the data storage unit 3. At the time of board production in which the arrangement of the component supply device 20 is the same as the data 40, the component mounter 1 refers to the collation result recorded in the data storage unit 3 or the storage device 32 when switching boards, and the component mounting machine 1 Is implemented.

  Once such data has been created, if the production program for the board to be produced next is included therein, the collation result of the mounting state of the component supply device 20 is obtained by referring to that data. Can take over. As a result, if it is within the production program included in the common component supply device arrangement information, the result of checking the component mounting state that was first performed can be used no matter how many times the production program is read again. It is not necessary to check the mounting state of these parts, and it is possible to efficiently produce a wide variety of boards.
