Next, the operation of the mounted component setting error prevention apparatus 1 of the present embodiment having the above-described configuration and a method of using the same will be described with reference to the flowchart of FIG. Here, the electronic component storage case already set in the electronic component mounting machine (not shown) (automatically mounting the electronic component E on the board) is replaced with, for example, the next electronic component storage case because the case becomes empty. The case will be described.

First, as shown in FIG. 5, in step 100, the (first) bar code of the electronic component storage case set in the electronic component mounting machine is read by the bar code reader 3 and input. . Next, in step 110, the read content (data A) of the first barcode is displayed on the upper stage of the liquid crystal display device 7.

Further, in step 120, the (second) bar code of the next electronic component storage case prepared for replacement is read and input. Next, in step 130, the content (data B) of the newly read second barcode is displayed on the lower part of the liquid crystal display device 7.

Next, in step 140, data A and data B are compared to determine whether they match. If it is determined that they match, step 15
0, on the other hand, if it is determined that they do not match, the process proceeds to step 160. In step 150, since it is determined that they match, that is, it is determined that the electronic component storage case is correct, in order to notify the operator to that effect,
The buzzer sounds once and the green LED 9a is turned on. The green LED 9a may be turned off after a predetermined time, turned off by the key switch 13, or turned off automatically at the time of reading the next first bar code. Good.

On the other hand, in step 160, since it is determined that they do not match, that is, it is determined that the case is the wrong electronic component storage case, the buzzer 11 is intermittently turned on in order to notify the worker of the fact. And the red L
The ED 9b is turned on. At step 170, it is determined whether or not the release switch 13b is turned on. If the release switch 13b is turned on, it is confirmed by the operator that the switch 13b is turned on.
In step 180, the buzzer 11 is turned off,
The red LED 9b is turned off.

Thereafter, the flow returns to step 100 to repeat the same comparison judgment processing. As described above, in this embodiment, the first barcode displayed on the set electronic component storage case and the second barcode displayed on the electronic component storage case to be mounted next are read, and these are read. By comparing whether they match, it is possible to easily determine whether the electronic component storage case to be mounted next, that is, the electronic component E is correct. Accordingly, even if there are many names of electronic components E that are very similar, the operator can easily and surely recognize the difference, so that there is a remarkable effect that an erroneous electronic component E is not attached to the board.

Next, another embodiment will be described. Here, an example in which a bar code indicating the type of electronic component to be placed on the electronic component mounting machine is displayed in the specification will be described with reference to FIG. First, as shown in FIG. 5, when the electronic component storage case is first mounted (set) on the electronic component mounting machine, in step 100, the (first) bar code displayed on the specification is changed to The information is read by the barcode reader 3 and input.

Next, in step 110, the contents (data A) of the read first barcode are stored in the liquid crystal display
Is displayed in the upper row. Further, in step 120, the (second) barcode of the electronic component storage case prepared for newly setting is read and input.

Next, in step 130, the contents (data B) of the read second barcode are stored in the liquid crystal display
Is displayed at the bottom. Hereinafter, the processing of steps 140 to 180 is performed in the same manner as in the above embodiment. In the present embodiment, unlike the above-described embodiment, the first barcode of the specification is compared with the second barcode of the electronic component storage case. According to this method, the same effects as those of the above embodiment can be obtained, and it is particularly effective when the electronic component storage case is not first set in the electronic component mounting machine.

It is needless to say that the present invention is not limited to the above-described embodiment, and can be implemented in various modes without departing from the gist of the present invention. For example, instead of providing the first barcode on a document such as a specification, a label printed with a barcode may be attached to the main body of the electronic component mounting machine, or a tag provided with the barcode may be attached to the main body. Good.

In addition to the case where the electronic component storage case is first set in the electronic component mounting machine and the case where the already set electronic component storage case is replaced, the electronic component storage case is provided in a place other than the electronic component storage case such as a specification. The first barcode provided may be used. In addition, mounting component setting errors in each of the above embodiments.
The prevention device is separate from the electronic component mounting machine.

The present invention can be applied not only to electronic components but also to various articles, and the object to be attached can be various types other than the substrate, and is not particularly limited.
