Description

  The present invention relates to a component mounting method, and in particular, reduces the number of teaching operations for the acquisition target position coordinates of components supplied from a feeder, which is required when a feeder bank equipped with a feeder that supplies components is switched. The present invention relates to a component mounting method that can be performed.

  Conventionally, for example, a component mounting apparatus 10 as shown in FIG. 1 (front view) and FIG. 2 (side view) is used to mount components on a substrate.

  The component mounting apparatus 10 includes a main body unit 12 that mounts components on a board, and a component supply unit 14 that supplies components to the main body unit 12.

  The component supply unit 14 includes a feeder 16 that supplies components, a feeder bank FB to which the feeder 16 is mounted, and an exchange truck 20 that mounts the feeder bank FB. In FIGS. 1 and 2, the part other than the component supply unit 14 is the main body 12.

  FIG. 3 is an enlarged side view showing a portion III in FIG. 2. For convenience of illustration, FIG. 3 shows a state before the feeder bank FB is positioned and fixed with respect to the main body portion 12.

  After the plurality of feeders 16 are attached and fixed to the feeder bank FB attached to the exchange cart 20, the exchange cart 20 is moved in the arrow direction (right direction in the figure). Then, the feeder bank FB is lifted by the lift positioning device 30 including the air cylinder 32 and the lifter 34, and is positioned and fixed to the main body 12 of the component mounting device 10.

  Specifically, the first positioning pin 36 provided on the upper surface of the lifter 34 that is driven up and down by the air cylinder 32 is fitted into the hole 22 provided in the lower surface of the feeder bank 18, and is formed on the upper surface of the feeder bank FB. The feeder bank FB is inserted into the hole 42 provided in the positioning portion 40 of the main body portion 12 of the component mounting apparatus 10 indicated by the phantom line, so that the feeder bank FB is inserted into the main body portion 12 of the component mounting apparatus 10. Positioning and fixing.

  After the feeder bank FB is positioned and fixed with respect to the main body portion 12 in this way, the component mounting apparatus 10 operates according to the production program and sucks the components supplied from the feeder 16 with a mounting head (not shown). Then, the mounting head is moved to a predetermined position above the substrate to mount the component on the substrate. In this case, the production of the component mounting board (component mounting) is performed by creating production program data for producing the component mounting board for each board type. Each production program data includes various data for producing a component mounting board in the component mounting apparatus 10. For example, the data related to the board, the data related to the mounting position, the data related to the part (for example, the height and width dimensions), and the suction position It consists of data, information for image recognition, data concerning application of adhesive, and the like.

  When a plurality of types of component mounting boards are produced, the mounted components are different for each production program data. Therefore, the types of feeders 16 that supply these components are also different, such as replacement and rearrangement of the feeders 16. Preparatory work is required. Therefore, in order to efficiently perform the production (component mounting) of the component mounting board using the plurality of production program data in the shortest time, the plurality of production program data is clustered as if it were one production program data. ing. In the clustered production program data (hereinafter referred to as clustered production program data), the optimal arrangement of the production program data and the feeder 16 so that the feeder 16 does not need to be rearranged even if the type of board changes. Has been made. For this reason, in the same clustered production program data, even if the type of substrate changes and the production program data changes, it is not necessary to rearrange the feeder 16.

  Here, although the feeder 16 is attached to the feeder bank FB, the attachment position of the feeder 16 has an error. For this reason, a deviation occurs between the suction position (acquisition target position coordinates) in the production program data and the actual component supply position in the feeder 16. Accordingly, the parts supply position data of the feeder 16 is acquired, and teaching is performed to reflect this in the suction coordinates (the coordinates targeted when the mounting head picks up the parts (acquired target position coordinates)) of the production program data. Yes. By performing this teaching, the mounting head moves to an accurate component supply position and can accurately adsorb the components.

  However, such teaching work is conventionally performed for all the feeders 16 every time the production program data is switched, even within the same clustered production program data, and the work efficiency of production of the component mounting board is deteriorated. There was a problem.

  On the other hand, in Patent Document 1, when the production program data is switched within the same clustered production program data, the component supply position data of the feeder 16 used in the production program data before the switching is A technique for using data is described. According to this technique, the number of teaching operations performed by acquiring component supply position data of a feeder 16 to be used again can be reduced, and board production efficiency can be improved. It becomes possible.

  However, the technique described in Patent Document 1 is effective when the same feeder bank FB is used. However, when the feeder bank FB is replaced and a different feeder bank FB is used, all the feeders to be used are used. It was necessary to perform teaching work on No. 16 and acquire component supply position data to correct the suction coordinates (acquired target position coordinates) which are the coordinates of the suction target position by the mounting head. The suction coordinates for the feeder 16 can only hold one latest suction coordinate for each position on the feeder bank FB to which the feeder 16 is attached in the host line computer 50 (see FIG. 4). This is because the.

  The present invention has been made in view of such a problem, and reduces the number of times of teaching work of the acquisition target position coordinates of the feeder even when the feeder bank is replaced and a different feeder bank is used. It is an object of the present invention to provide a component mounting method capable of achieving the above.

  A component mounting method according to the present invention is a component mounting method in which teaching for correcting the acquisition target position coordinates of a component supplied from a feeder mounted on a feeder bank is performed, and the component is mounted at a predetermined position on a board. A takeover file that stores the acquired target position coordinates corrected by the teaching is provided for each feeder bank, and when the feeder bank is switched, production program data that reflects the acquired target position coordinates stored in the takeover file is provided. The present invention solves the above-mentioned problems by downloading to a component mounting apparatus.

  According to the present invention, a takeover file for storing the acquired target position coordinates corrected by teaching is provided for each feeder bank, and when the feeder bank is switched, the acquired target position coordinates stored in the takeover file are reflected. Since the production program data is downloaded to the component mounting apparatus, the number of teachings can be reduced, and the production efficiency of the component mounting board can be improved.

  Hereinafter, a component mounting method according to an embodiment of the present invention will be described in detail with reference to the drawings. In the component mounting method according to the present embodiment, a feeder is attached and fixed to a feeder bank and components are supplied. Since the present invention can be applied to a component mounting apparatus, in the following description, a case where the component mounting method according to the present embodiment is applied to the component mounting apparatus shown in FIGS. 1 to 3 will be described.

  FIG. 4 is a diagram schematically showing an example of a production line to which the component mounting method according to the present embodiment can be applied, together with the control configuration of the host line computer 50 of this production line, and FIG. 5 shows the configuration of this production line. It is a block diagram which shows the control structure of the component mounting apparatus 10 to do. First, the configuration shown in FIGS. 4 and 5 will be described.

  The host line computer 50 manages a plurality of component mounting apparatuses 10 constituting one production line necessary for manufacturing a product (component mounting board), and manages the production line.

  As shown in FIG. 4, the host line computer 50 includes a control unit 61, a data output unit 64, a data input unit 65, a data storage unit 66, and a data transmission / reception unit 67. The control unit 61 includes a CPU 61a, a RAM 61b, and a ROM 61c, and data, calculation results, and the like of the host line computer 50 are output from the data output unit (monitor) 64.

  Further, production program data or the like is input to the data input unit 65 via an input unit such as a keyboard, and data from the component mounting apparatus 10 is received by the data transmission / reception unit 67. These data can be stored in the data storage unit 66. The RAM 61b, ROM 61c, or data storage unit 66 stores an operating system program (OS), a program for executing this embodiment, and various data.

Further, the data storage unit 66 is provided with suction coordinate takeover files F _{1 to} F _n corresponding to the feeder banks FB _{1 to} FB _n to be used. In the actual mounting operation, the component supply position data of the feeder 16 attached to the feeder bank FB is acquired, and based on the result, the suction coordinates (acquired target position coordinates) that are the coordinates of the suction target position by the mounting head are corrected. The corrected suction coordinates (acquired target position coordinates) are stored in the suction coordinate takeover files F _{1 to} F _n corresponding to the feeder banks FB _{1 to} FB _n to be used, respectively. The feeder banks FB _{1 to} FB _n are placed on the feeder bank storage place 70 when not attached to the component mounting apparatus 10, and are attached to the component mounting apparatus 10 when used for production of a component mounting board.

  Production program data including various data necessary for producing a component mounting board in the component mounting apparatus 10 can be input to the host line computer 50 via the data input unit 65 in a completed form. The host line computer 50 can also create each substrate based on various data input via the data input unit 65.

  The component mounting apparatus 10 includes a control unit 81 including a CPU 81a that controls the entire component mounting, a ROM 81c that stores various control programs and data, and a RAM 81b that stores control data and processing data and provides a work area. Yes. Further, the component mounting apparatus 10 is provided with a data transmission / reception unit 86 capable of transmitting / receiving data to / from the host line computer 50. Production programs and production program data transmitted from the host line computer 50 are The data is received via the data transmission / reception unit 86 and stored in the data storage unit 85. The control unit 81 drives the X / Y drive unit and other drive units 82 in accordance with the production program transmitted from the host line computer 50, production program data, and data input via the data input unit 83, The mounting head is moved above the feeder 16, and the electronic components supplied from the feeder 16 are attracted to the mounting head. The sucked component is recognized by the image recognition unit 84 provided with a camera, and the orientation of the component is corrected. Then, the mounting head moves above the substrate conveyed along the substrate conveyance path (not shown) and clamped at a predetermined position, and the sucked component is mounted at a predetermined position on the substrate.

Here, as described above, the component supply position data of the feeder 16 attached to the feeder bank FB is acquired before the mounting head sucks the component, and the suction coordinates (acquisition of the suction target position by the mounting head are acquired. Teaching is performed to correct (target position coordinates). In the component mounting method according to the present embodiment, the corrected suction coordinates (acquired target position coordinates) are taken over by the suction coordinates corresponding to the feeder banks FB _{1 to} FB _n to be used. Since the files F _{1 to} F _n are stored for each feeder bank FB _{1 to} FB _n , even _if the feeder bank FB is replaced when the production program data is switched, the adsorption coordinate transfer file corresponding to the replaced feeder bank FB By reading F, the number of teaching operations of the suction coordinates (acquired target position coordinates) of the feeder 16 can be reduced. Can.

  Next, a processing procedure by the component mounting method according to the present embodiment that brings about such an effect will be described based on a flowchart shown in FIG.

  First, production program data of a production program to be executed is input to the host line computer 50 or created in the host line computer 50 based on the input data and stored in the control unit 61 of the host line computer 50 (step S1). ). Here, in the production program data, the adsorption coordinate takeover file F corresponding to the feeder bank FB used for production is linked (numbers 1 to n of the adsorption coordinate takeover file F are used as link numbers), and the adsorption coordinate takeover file is obtained. The suction coordinates (acquired target position coordinates) stored in F are reflected in the production program data. Also, red or blue color is set for each link number, and the number and color are assigned to the feeder bank FB corresponding to the link number by attaching a sticker with that number and color. Display it.

  Next, the control unit 61 performs processing for reflecting the suction coordinates (acquired target position coordinates) stored in the suction coordinate takeover file F in the production program data. Specifically, first, the control unit 61 is linked to the production program data. The adsorption coordinate takeover file F is selected (step S2). Then, the value of the suction coordinates (acquisition target position coordinates) stored in the selected suction coordinate takeover file F is reflected in the suction coordinates (acquisition target position coordinates) of the production program data (step S3). The data output unit (production screen) 64 of the host line computer 50 displays the link number and the color corresponding to the number (step S4). The operator can easily find the feeder bank FB to be attached to the component mounting apparatus 10 by attaching a sticker with the number and color of the corresponding adsorption coordinate takeover file F to the feeder bank FB. . Thereby, it is possible to prevent the feeder bank FB from being overlaid. If the suction coordinate takeover file F is not linked to the production program data, the suction coordinate takeover file F to be used can be designated.

  Then, the production program data reflecting the value of the suction coordinates (acquired target position coordinates) stored in the suction coordinate takeover file F is downloaded from the host line computer 50 to the component mounting apparatus 10 (step S5). For the feeder 16 that does not include the suction coordinates (acquired target position coordinates) data in the downloaded production program data, the suction coordinates are taught and reflected in the production program data (step S6) to produce the component mounting board. Is started (step S7).

  As described above, in the component mounting method according to the present embodiment, even if the feeder bank FB is replaced with the switching of the production program data, the feeder 16 that needs to perform teaching of the suction coordinates (acquired target position coordinates) is Since only the feeders that do not have the adsorption coordinates (acquired target position coordinates) data in the coordinate takeover file F and only a limited number of feeders 16 need to be taught, the number of teaching operations can be reduced.

  When the production of the component mounting board is completed (step S8), the production program data reflecting the suction coordinates (acquired target position coordinates) obtained by teaching is uploaded (step S9).

  Then, the control unit 61 performs processing to reflect and save the suction coordinate (acquired target position coordinate) data of the uploaded production program data in the suction coordinate takeover file F. Specifically, first, the production program The adsorption coordinate takeover file F linked to the data is selected (step S10). Then, the suction coordinate (acquired target position coordinates) data of the production program data is reflected in the selected suction coordinate takeover file F and stored (step S11). Further, the old and new production program data are combined and stored (step S12).

  If there is a next production program, the process returns to step S1 to produce the component-mounted board, and if there is no next production program, the series of processes is terminated (step S13).

  As described above, in the component mounting method according to the present embodiment, since the suction coordinate takeover file F is provided for each feeder bank FB and is used properly, the suction coordinates (acquired target position) obtained by teaching once. (Coordinate) data is held in the suction coordinate takeover file F corresponding to each feeder bank FB. For this reason, even if the feeder bank FB is exchanged as the production program data is changed, it is only necessary to teach the feeder 16 whose suction coordinate data is not stored in the corresponding suction coordinate takeover file F, thereby shortening the setup time. be able to.

  Further, in the production program data, since the adsorption coordinate takeover file F corresponding to the feeder bank FB used for production is linked, the adsorption coordinates (acquisition target position coordinates) are set between the production program data and the adsorption coordinate takeover file F. It is easy to collate the data and keep the latest adsorption coordinates (acquisition target position coordinates).

  Also, the suction coordinate transfer file F and the feeder bank FB are linked by color and number, and the color and number of the feeder bank FB used for production are displayed on the production screen, so that the feeder bank FB used for production is visually recognized. Therefore, it is possible to shorten the feeder bank switching time and to prevent the feeder bank FB from being overlaid.

  Note that the component mounting method according to the present embodiment can be applied to any component mounting apparatus in which the feeder 16 is attached and fixed to the feeder bank FB to supply components. The number of mounting heads of the component mounting apparatus may be one or plural. Further, the method of holding the component by the mounting head may not be suction, and for example, a method of holding the component by sandwiching it from both sides may be used.

  The production program data to be used can be used regardless of whether it is clustered or not, but is preferably clustered.

  Even if a feeder bank FB that is not used in production program data used for production is placed in the feeder bank storage place 70, the component mounting method according to the present embodiment can be used, and the suction coordinate takeover file F and the feeder are used. When the bank FB is linked by color or number, even if a feeder bank FB not used for production is placed in the feeder bank storage place 70, it is easy to find the necessary feeder bank FB. The switching time can be shortened and the feeder bank FB can be prevented from being overlaid.
