Application process of laser welding machine on capacitor shell
With the rapid development of electronic information technology, the update speed of digital electronic products is getting faster and faster. The production and sales of consumer electronic products such as flat-panel TVs (LCD and PDP), notebook computers, digital cameras and other products continue to grow, which has driven The capacitor industry is growing. As the demand for capacitors increases, its quality requirements are getting higher and higher. According to market analysis, the processing of capacitors often determines the quality of capacitors. Durable capacitor components are generally obtained by fine welding processes. Use laser welding to process capacitors! Nowadays, there is a continuous laser welding machine that is specially used for capacitance welding in the welding market. The following describes the application process of the laser welding machine on the capacitor shell.
Generally, the thickness of the capacitor shell is required to be less than 1.0 mm, and mainstream manufacturers currently use two types of shell material thicknesses of 0.6mm and 0.8mm according to the battery capacity. Welding methods are mainly divided into side welding and top welding. The main advantage of side welding is that it has a small impact on the inside of the cell and the spatter will not easily enter the inside of the cover. Since the welding may cause bumps, which will have a slight impact on the subsequent assembly process, the side welding process has higher requirements on the stability of the laser, the cleanliness of the material, and the matching clearance between the top cover and the shell. The top welding process can be welded on one surface, so it can use a more galvanometer scanning welding method, but it has high requirements for the previous process to enter the shell and positioning, and it has high requirements for the automation of the equipment.
