BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) FIG. 1 is a perspective view showing a configuration of a mounting board appearance inspection system according to Embodiment 1 of the present invention, FIG. 2 is a block diagram showing a configuration of the appearance inspection apparatus, and FIG. It is a block diagram of a system. First, an appearance inspection system will be described with reference to FIG. In FIG. 1, there are a plurality of electronic component appearance inspection lines 1 (3 in the first embodiment).
Of the visual inspection devices 2A, 2B, and 2C.
The visual inspection devices 2A, 2B, 2C are interconnected by a LAN system 3, which is a network means. Further, a personal computer 4 which is a management computer of the visual inspection line 1 is connected to the LAN system 3.
The personal computer 4 receives and stores the information of the inspection result for each mounting board to be inspected sent from each of the visual inspection devices 2A, 2B, 2C, and displays the information on the monitor screen as needed.

Next, the appearance inspection apparatus 2A will be described with reference to FIG. The appearance inspection devices 2B and 2C have the same configuration. In FIG. 2, the inspection unit 20 includes a camera 6 and illumination 7, and the camera 6 captures an image of the mounted substrate 5 placed on the positioning unit 8. The imaging data obtained by the camera 6 is converted into image data by the inspection circuit unit 21 and sent to the inspection processing unit 22.
The inspection processing unit 22 performs image processing on the image data, determines an inspection target item (for example, a displacement of an electronic component on the board 5), and outputs the result as an inspection result. The content of the output data is data specifying the mounting board 5 to be inspected, data indicating the number of defective components of the mounting board 5 and the type of the fault.

The inspection result output from the inspection unit 20 is temporarily stored in an inspection result temporary storage unit 23. The inspection result output destination specifying means 24 specifies an output destination to output the data stored in the inspection result temporary storage unit 23. Here, as the output destination of the inspection result, two types of designation can be performed by selection. One is that the inspection result is output by the inspection result output means 25 as indicated by an arrow a, which is a network means LA.
The selection is to output to the outside via the N system 3, and the other is to select to transfer the data to the inspection result storage unit 27 provided in the visual inspection device 2A, as indicated by the arrow b.

Further, the appearance inspection apparatus 2A includes an inspection result input means 26 for receiving inspection result data of the other appearance inspection apparatuses 2B and 2C via the LAN system 3. The data of these other visual inspection devices 2B, 2C
As shown by the arrow c, the data is sent to the test result synthesizing means 28 via the test result input means 26, where the test result storage section
Is combined with the data of the inspection result by the inspection apparatus 2A stored in the storage device. That is, for the same substrate 5, the data of each inspection target item distributed to the visual inspection devices 2A, 2B, and 2C are grouped for each same mounting substrate to obtain a final inspection result covering all inspection items. The data of the final inspection result is stored in the final inspection result storage unit 29, and is output to the outside via the LAN system 3 by the final inspection result output unit 30 as necessary.

Next, as shown in FIG. 3, the final inspection result is received by the final inspection result receiving means 41 of the personal computer 4 and stored in the final inspection result storage section 42. Here, the contents outputted as the final inspection result include data for specifying the mounting board 5 for each mounting board 5, data of the number of the defective component, and data indicating the type of the defect (for example, component displacement, solder defect, etc.). limited. Therefore, these data alone are not enough for the operator to actually repair the defective part, so that the inspection board information 4 stored in the personal computer 4 is not sufficient.
4, the detailed information of the mounting board 5 is read, and an inspection result screen is created based on the final inspection result and the detailed information of the mounting board 5. The inspection result screen indicates the positions of components on the board requiring repair and the type of repair required, and is displayed on the monitor screen of the personal computer 4 by the inspection result information screen output means 43. This allows
The operator can easily understand the position of the repair place in the mounting board 5 and the type of the repair, and can improve the efficiency of the repair work.

As described above, in the first embodiment, a plurality of appearance inspection apparatuses 2A, 2B,
A specific one of C (usually a visual inspection device that is in charge of the final inspection item is selected) is made to collect a single final inspection result including an inspection result by another visual inspection device. It was done. Thus, when repairing the mounting board 5 after the appearance inspection, the operator does not need to individually refer to the inspection results sent from the plurality of appearance inspection apparatuses 2A, 2B, and 2C as in the related art. Can be performed at the same timing by referring only to a single final inspection result.

(Embodiment 2) FIG. 4 is a block diagram of a visual inspection system according to Embodiment 2 of the present invention. In FIG. 4, the inspection result output from the inspection unit 20 of the visual inspection device 2A is temporarily stored in the inspection result temporary storage unit 23. Thereafter, the output destination is specified externally by the inspection result output destination specifying means 24, and the LAN is output by the inspection result output means 25.
Output to system 3. The appearance inspection devices 2B, 2
Similarly, the inspection result is output to the LAN system 3 from C.

Each of these visual inspection devices 2A, 2B, 2C
Is input to the inspection result input means 46 of the personal computer 4. These inspection results are collected for each mounting board 5 to be inspected, and synthesized as a single final inspection result by the inspection result synthesizing means 47, and the final inspection result storage unit 42
Is stored. As described above, in the second embodiment, the synthesis of the inspection results is performed by the personal computer 4 which is the management computer of the appearance inspection line 1. The processing after the synthesis of the inspection results is the same as that of the first embodiment.

[0018]

According to the present invention, in a visual inspection system composed of a plurality of visual inspection devices, individual inspection results of the same substrate by a plurality of visual inspection devices are output as a single final inspection result. Therefore, when repairing the mounting board after the appearance inspection, there is no need to individually refer to the inspection results output from each appearance inspection device as in the past, and based on only a single final inspection result. In addition, all necessary repairs can be performed at the same timing, and workability during repair can be improved.
