When producing printed wiring boards, many electronic components need to be soldered to the surface of the bare board.

[0003] The existing application number is CN202023346441.7, which is a welding device for processing printed circuit boards, comprising a base plate, long holes are provided on both sides of the top of the base plate, a frame is fixedly connected to the bottom of the base plate, a first motor is fixedly connected to the left side of the frame, the right end of the first motor shaft passes through the inner cavity of the frame and is fixedly connected to a first threaded rod, the surfaces of both ends of the first threaded rod are threadedly sleeved with movable plates, the top of the movable plate passes through the long hole and extends to the top of the base plate, the top of the opposite side of the movable plate is fixedly connected to a spring, the end of the spring away from the movable plate is fixedly connected to a clamping plate, and the rear side of the top of the base plate is fixedly connected to a connecting plate. The utility model solves the problem that most of the existing printed circuit boards are spot welded by manual handheld welding machines, the work efficiency is low and the precision is low, and the fume generated by welding cannot be filtered and purified, and is easily inhaled by the body, affecting physical and mental health. This solution can be performed one by one through soldering liquid, but it is not easy to operate for small components and is time-consuming. In this solution, the exhaust gas inside the rack is extracted and filtered. After welding and filtering are completed, it is necessary to wait for the weld to dry before proceeding to the next step, which takes a long time. For this reason, we propose an easy-to-use welding mechanism. Utility Model Content
