[0049] The MES module 310 is connected to the code scanning mechanism 2 and is used to obtain and verify the collected PCBA board information.

[0050] The control module 320 is connected to the MES module 310 and is used to send a driving signal according to the verification result. Specifically, the control module 320 is used to send a code scanning instruction to the code scanning mechanism 2 according to the detection signal fed back by the photoelectric controller 1.

[0052] In one embodiment, the blocking mechanism 4 includes a blocking cylinder 410, a cylinder blocking connection block and a block 420. The blocking cylinder 410 is connected to the control module 3 in communication, the cylinder blocking connection block is connected to the piston of the blocking cylinder 410, and the other end of the cylinder blocking connection block is connected to the block 420.

[0057] The following is an explanation of the specific implementation process:

[0058] When the PCBA production conveyor belt is working and a PCBA board passes through the photoelectric sensor, the photoelectric sensor is triggered and sends a current signal to the control module. The control module receives and sends a scanning instruction to the scanner according to the current signal. The scanner scans the barcode and QR code, uploads the acquired information and sends it to the MES module. The MES module saves and detects the barcode information and QR code information to confirm whether the PCBA board information is correct and whether the PCBA board should be in this process. If the information is confirmed to be correct, the PCBA production conveyor belt works normally and the PCBA board passes normally.

[0059] If the detection result of the PCBA board information does not meet the requirements, such as the PCBA board information is wrong, the MES module feeds back a signal to the control module, and the control module sends a high level to the serial port driver module according to the signal. The input end of the serial port driver module receives the high level, and the double-control relay coil is energized and closed, and pins 3-5 of the first group of conversion contacts are closed, and pins 6-8 of the second group of conversion contacts are closed. At this time, the cylinder is blocked from working, causing the block to drop and block the PCBA board. At the same time, the red light of the prompt light is on, and an alarm is issued to the staff to remind them to check.

[0060] When the information is confirmed to be correct, the input end of the serial port driver module receives a low level, the double-control relay coil loses power, pins 3-4 of the first group of conversion contacts are closed, pins 6-7 of the second group of conversion contacts are closed, the blocking mechanism does not work, and the green indicator light turns on, indicating that the status is normal.

[0061] The utility model arranges a code scanning mechanism above a PCBA board production conveyor belt, collects barcode information and two-dimensional code information of a PCBA board in a current process, uploads the collected PCBA board information through a control module, detects the PCBA board information, and sends a blocking instruction according to the detection result; a blocking mechanism is arranged downstream of the code scanning mechanism along a moving direction of the PCBA board production conveyor belt, and the blocking mechanism performs a blocking action according to the blocking instruction to block the PCBA board whose detection result does not meet the requirements; the PCBA board of the current process is automatically scanned and detected, so that the product process is automatically recorded, and at the same time, the PCBA board whose detection result does not meet the requirements is prevented from entering the next process through the blocking mechanism, so as to ensure that the product record of the subsequent process is carried out normally.

[0062] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
