Through cooperation with one of the most famous laser spot welding equipment manufacturers in China, mylock developed a button battery laser spot welding machine, which realized the localization of laser welding foot battery technology.

Solder pin battery is a kind of button battery. By welding the button battery with solder pin, it accounts for a large proportion in the field of button battery.

Because button batteries are small and thin, unprofessional spot welding can cause great damage to button batteries, especially to the negative pole of button batteries. As shown in the internal structure diagram of button batteries, under the negative pole shell is lithium metal, which has very good conductivity and thermal conductivity, while lithium metal is in direct contact with the diaphragm inside the cell (to isolate positive and negative substances), so improper spot welding is easy The battery diaphragm is damaged and the button battery is short circuited internally.

Moreover, due to the activity of lithium, serious improper spot welding may even lead to explosion, fire and other accidents. Therefore, we suggest that non professional manufacturers and non professional personnel should use professional equipment and do not weld button batteries.

At present, resistance welding is used in most button battery factories in China. The principle of resistance welding is to use the thermal effect of resistance to heat fuse the welding piece and battery shell to form welding. This welding technology is convenient, low cost and firm, but the disadvantages are also obvious. The welding points are easy to cause oxidation, blackening and large front, and are operated by equipment and personnel Because of the large influence factors, it is easy to cause the button battery solder off, inaccurate size, or the battery voltage drop of the solder pin.

The laser spot welding technology adopted by miloc is the welding foot technology used by the international mainstream button battery manufacturers such as Panasonic, maxell, Sony, varta, etc. the welding has many advantages such as beautiful appearance, firmness, high consistency, small damage to the battery, accurate size, etc. it is the leading welding foot battery technology in China, and the domestic button battery spot welding technology is in line with the international level Representative.
