[0012] Hereinafter, FIG. 1 for one embodiment of the applied electronic component mounting line setup change process of the present invention will be described with reference to FIG.

In FIG. 1, a substrate supply device 2, a printing device 3 for printing and applying cream solder on a substrate, a component mounting device 4 for mounting chip components on a substrate, and a mounted state of the electronic component mounting line 1. An inspection device 5, a relay device 6 for temporarily storing a substrate and sending it to a subsequent process at a predetermined timing, an IC mounting device 7 for mounting an IC component on the substrate and joining its lead to an electrode on the substrate, Inspection device 8 for state and substrate storage device 9 for storing mounted substrates
Are arranged.

As shown in FIG. 2, in each of the working devices 3 to 8, a control unit 11 for controlling the operation of each of the working units 10 and a signal transmitted from the upper side of the mounting line 1 are provided. And a signal output from the control unit 11 are transmitted to the mounting line 1.
And a transmission unit 13 for transmitting data to the lower side of the transmission.

Further, only the transmission unit 13 is provided in the board supply device 2 at the head of the electronic component mounting line 1, and the board storage device 9 at the end is provided.
Is provided with only the receiving unit 12.

Then, various mounting devices 2 on the upper side and the lower side
The transmission unit 13 and the reception unit 12 of the relay device 6 are connected in series with the communication cable 14. Also, a branch cable 14 is provided from each communication cable 14.
a is extended and connected to the optical modules 15a to 15g, respectively. Each of the optical modules 15 a to 15 g is connected in a loop by an optical cable 16.
6 is connected to the board management device 17.

The substrate supply device 2 and the substrate storage device 9
Alternatively, a receiving unit 12 and a transmitting unit 13 may be provided so that a type switching signal is input from the outside to the substrate supply device 2 and a changeover completion signal is output from the substrate storage device 9 to the line of the next process.

In the above configuration, when the type of the board to be mounted on the electronic component mounting line 1 is switched, the last substrate of the previous type is printed from the board supply device 2 as the first mounting device of the electronic component mounting line 1. When the substrate is transported toward the apparatus 3, the type change switch provided on the substrate supply apparatus 2 is input. Then, a setup change start signal is output from the control unit 11 of the substrate supply device 2, and transmitted from the transmission unit 13 to the reception unit 12 of the printing device 3 through the communication cable 14. In the printing apparatus 3, when the setup change start signal received by the receiving unit 12 is input to the control unit 11, the control unit 11 determines that the loaded board is the last board of the previous type, and When the printing process is completed and the board is sent out to the component mounting apparatus 4 in the next step, the transmitting unit
A changeover start signal is output from 13 to the receiver 12 of the component mounting apparatus 4 in the next process, and the changeover of the printing apparatus 3 is performed so as to correspond to the next type of substrate.

Hereinafter, a setup start signal is sequentially transmitted to the control unit 11 as the final substrate is sequentially sent to the component mounting apparatus 4, the inspection apparatus 5, the IC mounting apparatus 7, and the inspection apparatus 8 in the subsequent process. As a result, in each of the devices 4 to 8, the setup change is automatically performed after the processing of the final substrate is completed. In the relay device 6, when a setup change start signal is input to the control unit 11 when the final board is carried in, the control unit 11 transmits the setup change signal to the IC mounting apparatus 7 in the next step. A replacement start signal is output.

When the setup change operation is completed, the control unit 11 of each of the devices 4 to 8 starts the operation of loading the next type of substrate, and thereafter repeats the predetermined operation.

On the other hand, since the setup change start signal transmitted from each of the devices 2 to 8 is also input to the optical modules 15 a to 15 g, the setup change signals are connected to these optical modules 15 a to 15 g in a loop by an optical fiber 16. It is possible to monitor the device from which the final substrate has been sent out by the substrate management device 17 and to grasp the progress of the setup change without performing complicated control and commands for each device. .

In the case of an electronic component mounting line in which the host computer transmits and receives control data to and from each of the devices 2 to 9, a setup change start signal is sent from the host computer instead of the input of the type changeover switch. Even if only the output is performed, each work device of the mounting line performs the sequential changeover operation in synchronization with each other even if the host computer does not output the changeover start signal to the individual devices 3 to 9 in a timely manner. , FMS (Flexible Manufacture System) and CIM (Computer Integrated Manufacturing).

Further, if an external input is connected to the control unit 11 of each of the devices 2 to 9 via an OR logic circuit, processing can be started from an arbitrary process, and it is possible to flexibly switch types during the process. It is also possible.

Further, in the above-described embodiment, an example is shown in which the present invention is applied to a mounting line for electronic components.

[0025]

According to the present invention, as described above, even between the working devices which operate independently and asynchronously with each other, when the product is switched, the working device in the first step is synchronized with the final object of the previous product. When a predetermined signal is issued, the setup command signal is sequentially transmitted to the working device of the next process in synchronization with the final object, so that the setup can be automatically and efficiently sequentially executed.
