Description

  The present invention relates to a mounting data creation method and apparatus suitable for use in creating mounting data used for controlling a mounting machine that mounts electronic components or the like on a substrate.

  2. Description of the Related Art Conventionally, a mounting machine has been used to mount electronic components on a wiring board such as a printed board. This type of mounting machine creates mounting data that determines the type, number, mounting position, etc. of components to be mounted according to the board to be mounted, and the feeder placement on the mounting machine is optimized according to the created mounting data. After preparation (preparation) before production such as changing to a converted position is performed, a board product is produced by executing control according to the mounting data.

  The mounting data used for this production is created by combining the mounting basic data including the mounting position created by the operator from CAD data for each target board and the component information including the characteristics of the components read from the database. However, the creation work was done manually by one file for each mounting machine.

  On the other hand, automation of this creation work has also been proposed. For example, Patent Document 1 discloses a database for registering information on components and equipment necessary for creating mounting data for a plurality of mounting machines, and CAD. There is disclosed a mounting data creation device that takes mounting position information from a device and creates mounting data.

  In addition, with the recent progress in electronics, electronic components have been downsized, and higher accuracy is required in mounting machines. The mounting data was corrected according to the actual mounting state, and the correction was made. There is a need to mount based on mounting data. For that purpose, the operator actually operates the mounting machine with the mounting data before the start of production, and the operator determines whether the reference mark on the board positioned at the position where the component is mounted is located directly below the recognition camera. If the position is deviated from the target position, information for correcting the amount of deviation is taught to the mounting machine, and teaching work for correcting the mounting data is performed (see, for example, Patent Document 2).

  The flowchart of FIG. 3 shows an overview of the procedure from the creation of conventional mounting data to the start of production.

  That is, the mounting data (production program in the figure) used for production includes the mounting position (coordinates on the board) of the component extracted from the CAD data for board design by the conversion program, the name of the component to be mounted, its mounting order, It is created by combining basic mounting data unique to the target board (CAD conversion data in the figure) and component information including component features read from the component database (step 11). The component information includes a component type such as a square chip, dimensions and shapes of various components, a supply form of components such as a tape and a stick, and a packing state such as a component storage pitch.

  When the production program is created, optimization is performed so that the moving tact time of the suction head when components are mounted on the program is minimized (step 12). The optimized production program is downloaded to each corresponding machine (mounting machine) (step 13).

  In each machine, preparation before production (replacement) is performed to change the actual arrangement to the feeder arrangement on the program optimized in step 12 (step 14), and then the substrate is actually transferred using the production program. Then, the teaching operation is performed after positioning (step 15), and then production is started.

  However, even if the mounting data can be automatically created as in the mounting data creation device disclosed in Patent Document 1, production is started on the mounting machine using the created mounting data. Therefore, as described in Patent Document 2, it is necessary to actually recognize the reference mark on the substrate in accordance with the mounting machine to be used, and to perform the teaching work for correcting the deviation, Since this is an operation that requires accuracy, there is a problem that it takes time to set up before production.

  The present invention has been made to solve the above-described conventional problems. When newly creating mounting data, teaching work for correcting deviation from the reference position of the substrate before production is performed for each mounting machine. It is an object of the present invention to provide a mounting data creation method and apparatus that can be omitted or simplified.

  The present invention is a mounting data creation method for creating mounting data for controlling a mounting machine by combining mounting component data including mounting positions of components according to a board to be mounted with component information relating to components to be mounted. Then, the reference mark teaching information of the board recorded as the position correction result data is extracted from the already produced mounting data actually used for production by the mounting machine, and the mounting data is imported into newly created mounting data. By completing the above, the above-mentioned problems are solved.

  The present invention is also a mounting data creation device for creating mounting data for controlling a mounting machine that picks up a component from a component supply unit with a suction head and mounts it at a predetermined position on a wiring board. Mounting data storage means for storing component information including the features of mounting as mounting data, mounting position data generating means for generating basic mounting data including a component mounting position corresponding to the board to be mounted, and components related to the mounted component Mounting data creation means for reading information from the mounting data storage means and creating mounting data by combining the component information and the mounting basic data created by the mounting position data creating means, and suction when mounting the component Recorded as position correction performance data from optimization means that optimizes component placement so that the head movement is minimized, and mounting data already produced. Extracting the reference mark teaching information of the substrate are, by providing a correction data input means for loading copy to the mounting data created, it is obtained by solving the above problems as well.

  According to the present invention, the reference mark teaching information of the board recorded as the position correction result data is extracted from the mounting data with the production results actually used in the production by the mounting machine, and is taken into the mounting data to be created. Therefore, when producing using newly created mounting data, the teaching work can be omitted or simplified, so that the time required for preparation before production can be greatly shortened.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing the relationship between a mounting data creation apparatus according to an embodiment of the present invention and a mounting machine that mounts electronic components using the created mounting data.

  The mounting data creation apparatus 10 of this embodiment includes a component database (mounting data storage means) 12 that stores component information that is mounting data related to components including the characteristics of the components such as shapes and dimensions, and a mounting target. A CAD conversion unit (mounting position data generating means) 14 for generating mounting basic data including a component mounting position corresponding to the wiring board, and component information related to the mounted component are read from the component database 12, and the component information and the CAD conversion unit 14 are read out. The editing function unit (mounting data creating means) 16 for creating mounting data for controlling the mounting machine by combining with the mounting basic data created by the above, and when the position correction of the board is performed before each mounting machine An actual BOC data storage unit 18 for storing actual BOC mark data which is teaching information (reference mark teaching information) acquired in A copy function unit 20 that copies and loads the actual BOC mark data of the corresponding mounting machine read from the data storage unit 18 into the mounting data created by the editing function unit 16, and mounts a component on the board with respect to the mounting data An optimization processing unit (optimization means) 22 for calculating the feeder arrangement in the component supply unit so that the moving tact of the suction head during the operation is minimized, and the optimized mounting data is output to the corresponding mounting machine In addition, a machine interface (correction data input means) 24 for inputting used mounting data after the production is completed is provided.

  The mounting data creation apparatus 10 creates mounting data for a plurality of mounting machines, downloads the created mounting data to a corresponding mounting machine, and performs production. Before starting production, a board mark (BOC mark) is added to the camera. Then, teaching is performed to correct the position by taking an image, and it is taken into the mounting data (production program) as teaching information of the BOC mark, and the mounting operation (production) is started. When the production is finished, the mounting data in which the teaching information is incorporated is uploaded to the mounting data creating apparatus 10, and the teaching information is stored in the actual BOC data storage unit 18 as actual BOC mark data. The method of saving is arbitrary, and the BOC mark data part may be extracted even with the production program (mounting data) already produced.

  Next, the operation of the present embodiment will be described with reference to the flowchart of FIG.

  First, the environment is set using an input device such as a keyboard (step 1). Specifically, the line configuration of the production station (mounting machine), the designation of the holder for creating the production program (mounting data), the designation of the file of the parts database 12, the production program for copying the BOC mark data (production completed mounting) Data) is specified. Based on this environment setting, production program creation, optimization processing, download, and the like described below are performed.

  The CAD data stored in the holder specified in the environment setting in step 1 is converted into a predetermined production program format by the CAD converter 14 to create mounting basic data including the mounting position and the like (step 2). Note that the CAD format and output format are also specified in advance in the environment setting stage.

  Next, the editing function unit 16 performs editing to combine the format-converted mounting basic data with component data (information) read from the component database 12, thereby creating a primary production program (mounting data). (Step 3). At that time, in the existing production program with a track record of use, if there is part pick-up data, the part data is read from the database 12 and only when there is a change that affects the pick-up position. Etc.), the suction data is automatically selected so as to be changed.

  Thereafter, the copy function unit 20 extracts and reads the teaching information of the actual BOC mark from the production program (implemented data with actual production) stored as a reference stored in the actual BOC data storage unit 18. A secondary production program copied to the production program and taught is used (step 4). However, the actual teaching information copying process is performed only when the line configuration to which the copy source production program is applied and the setting of the mark data match, and is not performed otherwise.

  If the production program that is the copy source of the BOC mark data is not designated, the teaching information is not copied, and the normal teaching in step 8 described later is performed on the station side after the production program is downloaded.

  After completing the data of the primary or secondary production program in step 3 or step 4, the feeder arrangement for the program is optimized, and a divided file suitable for the data structure of each station is created (step 5). ). Next, the production program optimized for each station is downloaded to the corresponding station (step 6).

  In the mounting data creation device 10 of this embodiment, the mounting data creation work from step 2 to download in step 6 is automatically executed. No. where the production program was downloaded. 1-No. In each station 30 to 34, preparation before production such as changing the feeder arrangement so as to match the result of the optimization process in step 5 is performed (step 7).

  After that, the board is actually transported, the board mark is captured by the camera at the positioned reference position, image recognition is performed, the teaching work for final position correction is performed, and the result is downloaded as the final teaching information. Incorporate into production program and start actual production.

  When the production of a predetermined number of board products is completed, the production program in which the final teaching information is incorporated as position correction performance data is uploaded to the mounting data creation device 10 and reflected in the next created mounting data. The actual BOC data storage unit 18 stores the data in a predetermined state.

  In addition, although the said 1st-step 6 demonstrated the operation | work process of one production program, it cannot be overemphasized that it can respond to a some production program by repeating this process.

  According to the embodiment described in detail above, the mounting data (production program) can be automatically created in a lump without performing the work of completing one file at a time from the CAD data. The creation time can be shortened.

  In addition, since the teaching teaching information can be extracted from the production program with production results in each mounting machine and imported into the production program, the newly created production program is applied to the mounting machine and production starts. Before performing the teaching work, when the substrate is transported, positioned, and the reference mark is imaged by the camera, the mark can be made to coincide with the vicinity of the center of the screen from the beginning.

  Therefore, this teaching work can be simplified and, in some cases, can be omitted, so that preparation time before production can be greatly reduced.

  Furthermore, by automating the work process from data creation to downloading, it is possible to save the man-hours and labor of the worker and to improve the work efficiency.

  In the embodiment, the mark data is read before the optimization process. However, the mark data may be read in the reverse procedure.
