In the field of electronic product manufacturing, manual welding technology is a relatively common production process, such as the welding process of connectors, cables, aviation plugs, etc., all using manual welding technology. After observation, it is found that the manual welding of components (round and small) such as aerial plugs and filter array boards during the product manufacturing process is heavy, and there are problems such as higher requirements for the welding skills of operators. The main reason is: when the operator solders the aerial plug-type circular device (because the device is round in shape, the worktable is not convenient to place it fixedly), it is necessary to hold the soldering iron with one hand to operate, and the other hand should The device plays a role of grasping and fixing, and it is necessary to flexibly rotate the device according to the welding situation. At the same time, the tin wire needs to be accurately sent to the welding site. The welding can be completed by skillful cooperation of both hands. The operator needs to be proficient in the whole process. Skills can be achieved, which requires operators to master the welding skills of such devices through a long period of practice and experience accumulation. Smaller devices such as filter array boards are placed on the workbench for soldering. Due to the light weight of the device itself, it cannot support the operating force of the soldering iron on the solder joints during soldering, and the device is easy to follow the direction of the force of the soldering iron. The welding quality also requires the operator to have certain operating skills to complete the welding. The above factors can easily lead to low efficiency in the production process, and the product quality cannot be effectively guaranteed. When the production batch is large, the problem is particularly prominent.
