A method, system, device and medium for detecting fixture space on a pcb board

Abstract

The invention discloses a method, system, device and storage medium for detecting fixture space on a PCB. The method includes the following steps: judging based on a keyword whether a device that needs to be supported by a fixture on the PCB to be inspected is a crimping piece; responding The device that needs fixture support on the PCB board to be inspected is a crimping part, and the size of the crimping part and the position of the pin are obtained; the fixture space on the device surface of the crimping part is locked based on the size, and the crimping part is locked based on the position of the pin. The jig space on the opposite side of the connector; and detecting whether there is a device in the locked jig space, and recording the position of the device and giving an alarm in response to the presence of the device in the locked jig space. The scheme proposed by the present invention distinguishes crimped parts and welded parts according to keywords, thereby determining the locked fixture space in different ways according to device types, ensuring the comprehensiveness of the inspection range, and the accuracy and reliability of the results.

Description

technical field [0001] The present invention relates to the field of PCB, more specifically, to a method, system, computer equipment and readable medium for detecting fixture space on a PCB. Background technique [0002] When the PCBA patch factory mounts the upper parts, the crimping parts need to be assembled with the support of machine tools. This support tool can be collectively referred to as the jig. The machine assembles the crimping parts to the PCB. Since the jig needs to be placed around the PCB crimping parts, when designing the PCB, there should be no other devices within the range of the crimping parts to prevent the The fixture interferes with other devices, resulting in damaged parts or poor crimping. Similarly, the same problem also exists for some soldering parts that need to be wave soldered. When the wave soldering is performed, the fixture will protect the devices around the PIN pin of the wave soldering, and it is also necessary to reserve a space for t...

AI Technical Summary

Problems solved by technology

[0003] Therefore, for crimping parts and welding parts, it is necessary to reserve sufficient fixture space. There cannot be devices placed in this fixture space. At present, to solve this problem, engineers generally control the space distance manually when designing PCBs. , manual visual inspection of whether there are misplaced devices in the fixture space, this processing method has a huge workload, wastes a lot of time and energy, and the detection is easy to miss, resulting in incomplete detection, leading to the problem of poor production and assembly damage

Therefore, once missed by manual inspection, it will cause unnecessary economic losses and a lot of reprocessing work.
