Abstract

PURPOSE:To provide an efficient part setting up method for setting a part cassette of a part mounting machine by which electronic parts are mounted on printed circuit boards. CONSTITUTION:A corresponding table for part names to arrangement numbers of parts cassettes 3 is provided in a control device 7 of a mounting device. A bar code reader 8 connected to a control device 7 reads out the part name of a parts cassette 3 on which the part name is put with a bar code. A parts cassette setting position is displayed on a display device 9 with the corresponding table, and a parts cassette setting table 1 is moved to a proper parts setting up position 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for efficiently installing a parts cassette of an electronic parts mounting machine for mounting electronic parts on a printed circuit board.

[0002]

2. Description of the Related Art FIG. 3 shows an example of a conventional method of replacing a parts cassette. Normally, when switching the model of the printed circuit board, the operator installs the parts cassette 3 carried by the carriage 2 on the parts cassette table 1 of the mounting machine. At this time, the table number is written on the parts cassette table 1. Further, the electronic component 4 is taped and fitted into the parts cassette 3, and the name of the component can be confirmed by the label 5 attached to the taping frame. Further, the operator has a correspondence table 6 in which the installation location of the parts cassette 3 is described. In this correspondence table 6, the part name and the installation number of the cassette table in which this part should be installed are associated with each other. Actually, the operator carries out the setup change of the parts according to the following procedure.

The part name of the taping frame fitted in the parts cassette 3 is confirmed. Referring to the correspondence table 6, the installation number of the parts cassette 3 corresponding to the corresponding part name is confirmed. The parts cassette 3 is installed by bringing the parts cassette 3 to the installation position of the parts cassette table 1 to which the installation number is attached.

[0004]

In such a conventional parts setup and replacement method, it is necessary to visually check the parts name and the parts cassette many times, so that the work is complicated and the installation location is incorrect. It takes time to generate or install. It is also necessary to take the parts cassette and move to the corresponding installation position. Some of recent mounting machines can install hundreds of cassettes, and the number of confirmations and the amount of movement are large, and the efficiency is greatly reduced in such work.

An object of the present invention is to solve the above problems and to provide an efficient method for changing parts.

[0006]

In order to achieve the above-mentioned object, the present invention has a correspondence table of component names and arrangement numbers of parts cassettes installed in the mounting machine in the control device of the mounting machine.
For a parts cassette in which the parts name is described in a bar code, a bar code reading device connected to the control device reads out the parts name of the parts cassette, searches for and displays the parts cassette installation position from the correspondence table, It comprises a second step of commanding an installation position and moving the parts cassette installation table to an appropriate parts setup replacement position.

[0007]

According to the present invention, the part name of the corresponding parts cassette can be easily read by the bar code reading device by the above-mentioned method, and the parts cassette table automatically moves to the operator's installation place, which is a complicated check. The work efficiency can be greatly improved because the work and the movement while holding the parts cassette are eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, the same components as those in the prior art are designated by the same reference numerals. As shown in the figure, a barcode reading device 8 and a display device 9 are connected to the control device 7 of the mounting machine, and the taping frame 11 fitted in the parts cassette 3 is read by the barcode reading device 8. Bar code label 10 with possible part names
Is attached. Also, parts cassette installation table 1
Can be moved to the left or right in response to a command from the control device 7.

FIG. 2 shows the flow of processing with the above-mentioned configuration. In step 100, the controller 7 has previously read a correspondence table between the part names and the installation numbers of the installation tables where the parts cassettes should be installed. Next, in step 110, the barcode reader 8 reads the name of the part attached to the taping frame 11 fitted in the parts cassette 3. In step 120, the installation number is retrieved from the correspondence table using the two component names as keys. In step 130, the installation device is output to the display device 9, and the operator confirms the number. Further, in step 140, based on the installation number, the control device 7 outputs a table movement command to the mounting machine so that the desired installation number comes to the setup change position.

[0011]

As described above, the present invention has a correspondence table of the part name and the sequence number of the parts cassette installed in the mounting machine inside the control device of the mounting machine, and the parts name is described by the bar code. For the cassette, the bar code reader connected to the controller reads the part name of the parts cassette, searches and displays the parts cassette installation position from the correspondence table, and the installation position is instructed, and the appropriate parts setup is performed. By the second process of driving the parts cassette installation table to the position, it is not necessary for the operator to visually confirm the part name and the parts cassette installation location many times when the setup is changed. Efficient and error-free work is possible because there is no need to move to a location.
