In order to improve the welding precision and efficiency, positioning tooling is usually used to fix the PCB board to ensure that it remains stable during the welding process. The traditional manual operation mode needs to be manually flipped, unbuckled and taken out after the PCB board flows out of the wave soldering equipment, which is a cumbersome process with low efficiency and has the following problems: 1. High labor intensity: the operator needs to frequently manually dismount the tooling, which is low in efficiency and prone to fatigue; 2. Poor consistency: manual operation cannot guarantee the consistency of each positioning and is prone to accidental collisions, affecting the welding quality; 3. Low safety: manual operation in a high-temperature environment has safety hazards such as burns.
