BACKGROUND OF THE INVENTION
The present invention relates to a production data creation method in an electronic component mounting apparatus for creating production data for an electronic component mounting apparatus constituting an electronic component mounting line.
[0002]
[Prior art]
An electronic component mounting apparatus used for manufacturing a mounting board is generally a general-purpose type, and the same mounting apparatus can be used for the production of various types of boards. When the type of board is switched, production data unique to each mounting apparatus is created based on mounting data given for each board, that is, data for specifying a component type and mounting position data. This production data is data for producing a mounting board designated as a production target by the mounting apparatus, and an electronic component is picked up from the component supply unit by the placement of the parts feeder in the component supply unit or the transfer head. Mounting sequence data indicating the order of mounting, mounting data indicating mounting position coordinates of individual components, and the like are included (see, for example, Patent Document 1).
The above-mentioned feeder data indicating the arrangement of the parts feeder is obtained by associating the feeder address indicating the feeder mounting position of the component supply unit with the part name indicating the type / standard of the electronic component, and thereby the mounting sequence. The feeder address to be accessed by the transfer head when the electronic component to be mounted is designated by is specified.

[Problems to be solved by the invention]
By the way, in many electronic component mounting apparatuses used in one mounting work place, it may be necessary to slightly change the control parameters in the mounting operation due to individual machine differences even in the same mounting model. For example, in the mounting operation in which an electronic component is taken out from the component supply unit by the transfer head and transferred and mounted on the board, if there is an operation delay or timing shift unique to each mounting device, the operation in these mounting devices is minimized. In order to synchronize, a process for synchronizing the mounting operation is performed by adjusting the suction timing when the transfer head picks up the component from the component supply unit and the mounting speed, which is the moving speed of the transfer head.
[0005]
In such a case, in the production data for executing the mounting operation, the component attribute data such as the mounting speed is applied to each electronic component mounting apparatus even for electronic components of the same type and standard. It is necessary to prepare a plurality of types in advance and distinguish these electronic components. For this reason, even for electronic parts of the same type and standard, data cannot be shared on the database storing production data, and it is necessary to prepare multiple types of data according to each electronic component mounting apparatus. The unified operation of the data that make up the system was hindered.
[0006]
Accordingly, an object of the present invention is to provide a production data creation method in an electronic component mounting apparatus that can uniformly operate data constituting a production data database.
[0007]
[Means for Solving the Problems]

The display unit 11 is a display monitor and displays an operation / input guidance screen.
[0014]
Next, the electronic component mounting apparatus will be described with reference to FIG. In FIG. 2, a conveyance path 12 is disposed in the electronic component mounting apparatus 1. The conveyance path 12 conveys the board | substrate 13, and positions it in the mounting position of an electronic component. A component supply unit 14 is disposed on the front side of the transport path 12, and a number of parts feeders 15 are arranged in parallel in the component supply unit 14. The parts feeder 15 stores a plurality of electronic parts held on a tape and supplies the electronic parts by pitch feeding the tape, and a vibration feeder that supplies the electronic parts stored in the stick by vibration. Includes types of feeders.
[0015]
The electronic component mounting apparatus 1 is provided with a transfer head 16 that is a mounting means. The transfer head 16 is moved by a head moving mechanism (not shown) and picks up an electronic component from a pickup position 15 a of the parts feeder 15. An electronic component recognition camera 17 is disposed between the transport path 12 and the component supply unit 14. The transfer head 16 holding the electronic component moves from the component supply unit 14 onto the camera 17 where the electronic component is recognized. Thereafter, the transfer head 16 moves onto the substrate 13 to mount the electronic component on the substrate 13.
[0016]
Next, the contents stored in the program storage unit 7 and the data storage unit 8 will be described with reference to FIG. First, the program stored in the program storage unit 7 will be described. The production data creation program 7a performs processing for creating production data necessary for performing the mounting operation by the transfer head 16, such as feeder arrangement data and mounting sequence data, based on the mounting data 8a and the device data 8b. It is a program.
[0017]
The optimization calculation processing program 7b is a program for performing calculation for the purpose of optimizing the mounting operation by the transfer head, and is executed in production data creation processing. In the production data creation process, the component name expansion processing program 7c is used on the production management data according to the individual electronic component mounting apparatus on which these electronic components are mounted even if the electronic components are of the same type and the same standard. When it is necessary to distinguish, this is a program for performing a process of adding an extension to the original part name to make a new part name.
[0018]
Next, data contents stored in the data storage unit 8 will be described. The mounting data 8a is design information about a production target object that indicates what kind of electronic component is mounted on which board on which the production target board is mounted. Here, the mounting coordinate data, the types of electronic components mounted on the mounting points, and the like are given for a plurality of board types to be produced in the form of specific data about the board.
[0019]
The apparatus data 8b is equipment information of an electronic component mounting apparatus used for production of a mounting board. Here, arrangement data such as a mounting stage for positioning the board, a feeder table for supplying the electronic parts to be mounted, and the electronic parts The configuration of the transfer head that takes out the component from the parts feeder arranged on the feeder table, transfers it to the substrate of the mounting stage and mounts it is given as unique data for each electronic component mounting apparatus.
[0020]
The production data 8c is data that is created for operating the electronic component mounting apparatus to produce a mounting board, and is created based on the mounting data 8a and the apparatus data 8b. In other words, by creating production data, the type, quantity, and arrangement of parts feeders on the feeder table, and the picking order and mounting order for picking up electronic components from the parts feeder and mounting them on the board by the transfer head The mounting sequence data shown is created, and the electronic component mounting apparatus is operated based on these data, whereby the mounting board as instructed by the design information is produced.
[0021]
In creating such production data, optimization is performed so that the work efficiency of taking out an electronic component by the transfer head and transferring and mounting it on the substrate is maximized under given conditions. In other words, even when mounting boards are produced based on the same mounting data, if the feeder arrangement and mounting sequence settings are inappropriate, the transfer head repeats unnecessary movements and repeats the same quantity of electronic components. The time required for mounting on the substrate is delayed and the mounting efficiency is reduced. For this reason, feeder arrangement and a mounting sequence that can shorten the time required for the mounting operation by the transfer head as a whole are calculated.
[0022]
Next, among the above-described production data, feeder arrangement data for determining feeder arrangement in the component supply unit 14 will be described. When the board type to be produced is switched, feeder replacement is performed in the component supply unit 14 to change the arrangement of the parts feeder 15 corresponding to the board type. That is, in order to supply the types and quantity of electronic components necessary for the production of the substrate, a necessary number of parts feeders 15 for supplying these types of electronic components are arranged.
[0023]
In this feeder arrangement, it is necessary not only to arrange the types and quantity of tape feeders corresponding to the electronic components to be mounted, but also to appropriately determine the arrangement of these parts feeders 15 in the component supply unit 14. In the mounting operation, the mounting operation in which the transfer head 16 reciprocates between the component supply unit 14 and the substrate 13, picks up an electronic component from these parts feeders 5, and transfers and mounts it on the substrate 13 is repeated frequently. For this reason, the operation efficiency of the transfer head greatly depends on whether or not the arrangement of the parts feeder 15 in the component supply unit 14 is appropriately matched with the mounting sequence. Therefore, when creating the feeder arrangement data for determining the feeder arrangement, the arrangement of the parts feeders 15 is determined for the purpose of optimizing the efficiency of the mounting operation by the transfer head.
[0024]
The feeder arrangement data is given in the form of a data table as shown in FIG. 4, and on the data table, each individual part is displayed in the feeder arrangement column provided corresponding to the feeder table address of the component supply unit 14. Feeder names (a, b,...), Component names (AAA1-0, AAA1-0,...) For specifying feeders, and other necessary data are allocated. By assigning feeder names on the data table, the position of the parts feeder 15 in the component supply unit 14 is fixed. The data format of the part name will be described later.
[0025]
Next, with reference to FIG. 5, part data indicating the component information of the electronic component mounted on each electronic component mounting line will be described. FIGS. 5A and 5B show examples of part data in the electronic component mounting lines L1 and L2, respectively. In these examples, chip-type electronic components having the shape of fixed resistor 1005 with the names of component names AAA1-0 and AAA1-1 are housed in units of 5000 on the same reel, and are used for small reels of 8 mm width. It shows that it is supplied by a tape feeder.
[0026]
The part data has a data configuration including control parameters required in the electronic component mounting apparatus when mounting the electronic component in addition to the data indicating the supply form as described above, and the part name is used as a key for the part. By reading the data, the control parameters for the mounting speed, the suction timing, etc. are also read at the same time and transmitted to the electronic component mounting apparatus for mounting the component.
[0027]
In the mounting workplace shown in the present embodiment, even when electronic components having the same function and the same standard are used, if different electronic component mounting lines are mounted, different control parameters are stored in the part data. Yes. For example, in FIG. 5A, the control parameters for mounting speed and suction timing are A and B, respectively, whereas in FIG. 5B, control parameters A1 and B1 different from these are set. . This is because a large number of electronic component mounting apparatuses used in one mounting workshop have individual machine differences even in the same mounting model, and it is necessary to correct such machine differences using control parameters. It depends.
[0028]
In this way, in the method of individually setting control parameters of different values for electronic components of the same function and the same standard, when the electronic component is read using the part name set based only on the function and the standard as a key, the control parameter The inconvenience that cannot be distinguished is caused. For this reason, conventionally, in order to avoid such inconvenience, it has been necessary to provide an independent database for each electronic component mounting line.
[0029]
On the other hand, in the part name in the production data shown in the present embodiment, the part name is configured in the data format as shown in FIG. 6, and the part name used here is narrowly defined based on the function / standard. And an extension (0, 1,...) Indicating that the component attribute such as the control parameter is different from the part name (AAA1, AAB1, and the like).
[0030]
That is, when there are electronic components of the same type and the same standard in a plurality of electronic component mounting lines and having component attribute data derived according to each electronic component mounting apparatus such as control parameters, the electronic component An extension corresponding to these component attribute data is attached together with the name of.
[0031]
In the mounting sequence data shown in FIG. 5C, the component name in the data format in which the extension indicating the code indicating the original characteristics of the component is used together with the mounting coordinates where the electronic component is mounted in each mounting operation. As a result, the function / standard of the electronic component is specified, and the control parameter corresponding to the electronic component mounting apparatus used for mounting is read correctly.
[0032]
As a result, common data can be used in the same database even in a mounting workshop equipped with a plurality of electronic component mounting lines with individual machine differences in the electronic component mounting device, realizing unified operation of production data Is done.
[0033]
【The invention's effect】
According to the present invention, when there are electronic components of the same type and the same standard and having different component attribute data corresponding to each electronic component mounting apparatus in a plurality of electronic component mounting lines, In the part data indicating the part information related to the part, the extension corresponding to the part attribute data is attached together with the name of the electronic part, so the electronic part mounting including a plurality of electronic part mounting apparatuses having inherent machine differences. Even when there is a line, the data constituting the production data database can be uniformly operated with the same database.
