BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component mounting apparatus, and more particularly to a component mounting apparatus having an automatic setup changing means having a function of preventing mistaken setup.

[0002]

2. Description of the Related Art In recent years, in a component mounting apparatus equipped with an automatic setup changer, an error setup prevention function has been emphasized in order to cope with high-mix low-volume production and variable-variation variable-volume production.

The error setup prevention function in the conventional component mounting apparatus will be described below.

FIG. 2 shows a system configuration of a component mounting apparatus having a function of preventing mistaken setup. In FIG. 2, reference numeral 1 is a device that holds setup change information such as a production plan and data necessary for setup change. Reference numeral 2 denotes a board determination device for determining the board type, which automatically determines the type of the board flowing from the upstream side. 3 is an automatic setup changer for automatically performing setup change, and 4 is a component mounter.

A setup changing operation for preventing an erroneous setup in the component mounting apparatus having the above configuration will be described with reference to FIG. First, the type of the board that arrives from the board determination device 2 as a setup change trigger is determined by the automatic setup changer 3
Transfer to. The automatic setup changer 3 determines whether or not the transferred board type is registered, and if not, checks whether the board is wrong or the registration data is wrong and displays a message. If it is registered, the setup change information is taken out from the setup change information holding device 1, the setup start signal is transferred to the component mounter 4, and the setup work is started. Next, after the setup change work is completed, the automatic mount changer 3 is started from the component mounter 4.
When the setup change work end signal is input to, the arrival board fetch signal is transferred to the component mounter 4, and the component mounter 4 fetches the board and starts production.

[0006]

However, in the above-mentioned configuration, after the board determination is made when the board arrives,
Transfer the setup change trigger, enter the setup change work,
Between the time the setup change is completed and the board is loaded,
Since the board is not judged again, if the board is pulled out or dropped during the setup and is replaced with a board of a different type during setup change, a board of a different type will be taken in. However, there was a problem in that it was produced in the wrong way.

In view of the above conventional problems, it is an object of the present invention to provide a component mounting apparatus capable of completely preventing erroneous setup even when substrates of different types are exchanged during setup exchange.

[0008]

A component mounting apparatus according to the present invention includes means for holding setup change information and setup change information according to the type of a board, which is automatically fetched from the holding means. Automatic setup changing means for performing
And a means for determining the type of the board when the board arrives and after the completion of the setup change operation and transferring the type of the board to the automatic setup change means.

[0009]

According to the present invention, according to the above-described configuration, the board type is determined again before the completion of the setup change and before the loading of the board, and it is determined whether the setup-changed version and the loaded board type are correct and then the board is loaded. Since the board is taken in, even if the board is removed or dropped during the setup and replaced with a board of a different type, the wrong setup can be completely prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A component mounting apparatus according to an embodiment of the present invention will be described below with reference to FIGS.

FIG. 2 shows a system configuration of the component mounting apparatus. Since the hardware system configuration is the same as that described in the conventional example, here, the names of the respective constituent elements will be listed again for explanation. Instead of. Reference numeral 1 is a setup change information holding device, 2 is a board determination device, 3 is an automatic setup change device, and 4 is a component mounter.

Next, the setup changing operation having the function of preventing mistaken setup by the above system configuration will be described based on the sequence of FIG. First, the type of board that has arrived from the board determination apparatus 2 as a setup change trigger is transferred to the automatic setup change apparatus 3. The automatic setup changer 3 determines whether or not the transferred board type is registered, and if not, checks whether the board is wrong or the registration data is wrong, and displays a message. If it is registered, setup information holder 1
The setup change information is taken out, and a setup change work start signal is transferred to the component mounter 4 to start the setup change work. Next, when the setup change work is completed and a setup change work end signal is input from the component mounter 4 to the automatic setup changer 3, the board is transferred before the arrival board capture signal is transferred to the component mounter 4. Wait for transfer of the board type from the determination device 2. Therefore, when the setup change operation is completed, the board determination device 2 again determines the type of the board and transfers it to the automatic setup change device 3. The automatic setup changer 3 determines whether the retransferred board type is the same as the set-up board type. Then, when the board types are different, it is judged whether or not the transferred board type is registered again, the setup change information is extracted, and the setup change operation is performed again. When the board types are the same, the board loading signal is transferred and the board is loaded by the component mounter 4 to start production.

As described above, according to the wrong setup prevention function of the present embodiment, it is possible to reliably prevent the wrong setup production due to the removal or dropping of the board during the setup change, which normally takes several minutes to tens of minutes.

Although the component mounter 4 and the board determination device 2 are separated in the above embodiment, a component mounter with a board determination device may be used. Further, although the automatic setup change device 3 and the setup change information holding device 1 are separated, an automatic setup change device with a setup change information holding device may be used. Further, as the component mounter having the automatic setup change function, the setup change information holding device 2, the board determination device 2, and the automatic setup change device 3 may be included in the component mounter 4.

[0015]

According to the present invention, the board type is determined again before the completion of the setup change and the loading of the board as described above, and it is determined whether the set up version and the loaded board type are correct. By loading the board after the setup, even if the board is pulled out or dropped during the setup and replaced with a board of a different type, incorrect setup can be completely prevented.
