[0002] In the production process of circuit boards, multiple processing technologies are required. One of the processing methods is wave soldering. Wave soldering is to directly contact the welding surface of the plug-in board with high-temperature liquid tin to achieve the welding purpose. The high-temperature liquid tin maintains an inclined plane, and a special device makes the liquid tin form a phenomenon similar to waves, so it is called wave soldering. Its main material is solder bar.

[0003] At present, in order to prevent defective plug-ins from flowing into the production line before wave soldering plug-in parts are welded, it is necessary to detect wave soldering plug-in parts. The existing detection method is that workers visually inspect whether there are defects such as missing parts, reverse parts, and wrong parts. There is a problem that defective products flow into production due to missed inspection during personnel operation, and manual visual inspection has low efficiency, consumes time and effort, and increases production costs.
