Abstract

PURPOSE:To reduce labors of the user of an electronic parts mounting device by adding a mount inhibited parts table without changing the electronic parts mounting program of the device. CONSTITUTION:A mount inhibited parts table is constituted in such a way that the table is stored in a RAM 8 like an electronic parts mounting program so that number registration and deletion to and from the table can be performed through a keyboard 9. A controlling means 10 recognizes electronic parts designated by mounting inhibited parts data and, when the same electronic parts (namely, the same electronic parts feeder) are designated in step data in the parts mounting program, works to suppress the mounting of the electronic parts corresponding to the step data. Accordingly, board production can be carried out while the mounting of electronic parts from a specific electronic parts feeder is inhibited without changing the parts mounting program. Therefore, labors of the user of this device can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an electronic component mounting method that is effective in performing reduced operation by excluding specific electronic components in an electronic component mounting apparatus.

[Prior Art] A plurality of electronic component feeders each housing a different type of electronic component (however, one type of electronic component is stored in one electronic component feeder) are arranged side by side on a component supply table to supply one component. The supply table is moved to sequentially bring the predetermined electronic component feeders to the component extraction position, and the electronic components are taken out from the electronic component feeders brought to the component extraction position using the suction nozzle of the electronic component transfer device. An electronic component mounting apparatus is known in which electronic components are mounted at predetermined positions on a circuit board (hereinafter simply referred to as a board) positioned by an XY moving table. The above operations in such an electronic component mounting apparatus are controlled by a control device according to an electronic component mounting program.

The electronic component placement program used in conventional electronic component placement equipment requires data that specifies a specific electronic component feeder on the component supply table from which the electronic component is to be taken out, and where on the board that is the object to be placed the electronic component that has been taken out. It is a set of multiple data (hereinafter referred to as step data) that is basically data that instructs where to attach the electronic component, and one step data corresponds to one electronic component. . Since electronic components are mounted on the board according to this electronic component mounting program, the number of step data in the electronic component mounting program matches the number of electronic components on the board.

On the other hand, recently, as described in Japanese Unexamined Patent Publication No. 61-76231, the same pattern can be created by adding data to each step data of the component mounting program in the book to instruct whether or not to execute it. A component mounting method has also been devised in which components are sequentially mounted on a board having different mounting patterns. In this case, the number of step data in one component mounting program does not necessarily match the number of electronic components on the board.

[Problems to be Solved by the Invention] By the way, in the above-mentioned electronic component mounting apparatus, electronic components from a specific electronic component feeder are not mounted on the board (this is called mounting prevention), and other electronic components are not mounted on the board. It may be desirable to mount only electronic components from an electronic component feeder onto a board. An example of such a situation is, for example, even if all the electronic parts that should be installed are not available due to a particular electronic component being out of stock, the installation is performed using only the electronic parts that are available. An example of this is when a completed board is later attached with unattached electronic components to create a complete board.

However, in the above-mentioned conventional technology, in this way, mounting of electronic components from a specific electronic component feeder is suppressed, and only electronic components from other electronic component feeders are mounted on the board, thereby effectively achieving board production. No consideration was given to repeating the process.

When producing such boards, it was necessary to change the five-component mounting program itself. In other words, it is necessary to delete all the step data in the electronic component mounting program that specifies the electronic component feeder of the electronic component to be suppressed, which requires a great deal of effort from the device user. There was a problem.

The present invention enables
The purpose of this system is to suppress the mounting of electronic components from a specific electronic component feeder so that circuit boards can be produced, thereby reducing the labor of the device user.

[Means for Solving Problem B] In order to achieve the above object, the present invention provides a component mounting method for an electronic component mounting apparatus as set forth in the claims.

[Operation] The control means recognizes the electronic component specified by the installation prevention component data, and adds the same electronic component (that is, electronic component feeder) to the step data in the component installation program.
If specified, it works to inhibit the mounting of the electronic component corresponding to the step data.

Thereby, it is possible to produce boards while suppressing the mounting of electronic components from a specific electronic component feeder without changing the component mounting program.

[Example] Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 6 is a perspective view of an example of an electronic component mounting apparatus to which the electronic component mounting method of the present invention is applied. 1 is a component supply table on which a plurality of electronic component feeders 2 can be mounted; 3 is a suction nozzle for taking out electronic components from the electronic component feeder 2 and mounting the electronic components onto a substrate 5 placed on an XY moving table 4; This is an electronic component transfer device. Further, 6 is a pedestal housing a control unit, and 7 is an operation panel.

FIG. 1, FIG. 2, and FIG. 3 are explanatory diagrams of the electronic component mounting method of the present invention. Figure 1 shows an electronic component mounting program, which includes X-coordinate and Y-coordinate data that instructs where to place the electronic component on the board, and component data that instructs the electronic component to be taken out using the electronic component feeder number. It consists of multiple step data. FIG. 2 is a table of electronic components to be prevented from being mounted, and up to four types of electronic components to be prevented from being mounted can be registered by electronic component feeder number. FIG. 3 is a flowchart of the control program, showing the procedure for mounting electronic components on a board. The operation of this example will be explained below using one flowchart.

First, step number n of the electronic component mounting program is set to 1 (■ in Fig. 3). Next, check whether the same value as the component data Pn of step number n is registered in the mounting inhibition tables A1 to A. Please check (■～■) in Figure 3.
If there is even one same value, proceed to ■, and only if there is no same value, parts are mounted using the step data of step number n (■ to ■ in Figure 3). Execution of parts mounting (Fig. 3 ■).

This is performed using the same control program as the conventional one.

Next, update the step number n (■ in Figure 3).

If the step number n does not exceed the step data number m, the process returns to (2) and the above-described process is repeated, and if n exceeds m, the process ends (■ in FIG. 3).

A specific example of mounting electronic components using the component mounting method of the present invention will be described below with reference to FIGS. 4 to 7.

FIG. 4 shows an example of an electronic component mounting program.

Originally, parts 12, parts 2, and parts 3 were placed on the board 5 as shown in Figure 5.
It was created for the purpose of mounting four types of electronic components, 9 parts 4, and the electronic component mounting program shown in FIG. 4 is the same as a conventional conventional electronic component mounting program.

Next, for some reason, for example, except for the electronic components of electronic component feeder numbers 2 and 4 (i.e., components 2 and 4), other electronic component feeders 1 and 3 are placed on the same board 5 as shown in FIG. If it becomes necessary to mount electronic components (ie, components 1 and 3), 2 and 4 are registered in the mounting prevention component table as shown in FIG. Then, as mentioned above, using the same electronic component mounting program as shown in Fig. 4,
Moreover, as shown in FIG. 7, electronic component feeder 1 is
and 3 electronic components (component 1 and component 3) can be mounted on the board.

FIG. 9 is a part of a block diagram of the control unit 6 that performs the above control, and the mounting prevention component table is stored in the RAM 5 similarly to the electronic component mounting program. Furthermore, the operation panel 7
The configuration is such that numbers can be registered and deleted from the mounting prevention parts table through the keyboard 9. Based on these data stored in the RAM 8, the CPU 10
The control program in II causes control operations to be performed as shown in FIG.

[Effects of the Invention] According to the present invention, by simply adding a mounting prevention component table without changing the electronic component mounting program, electronic components from a specific electronic component feeder registered in the mounting prevention component table can be added. Since it is easy to exclude parts and mount parts, and furthermore, to restore those that have been excluded, electronic component mounting equipment The user's effort can be significantly reduced.
