Description

Technical Field

[0002] The lithium battery cap is an important component of the lithium battery. It mainly plays the role of protecting and sealing the lithium battery. The cap is usually made of metal or plastic. Its surface design can prevent moisture, dust and other impurities from entering the battery, thereby ensuring the safety and stability of the battery. In addition, there is usually a safety valve on the lithium battery cap. This safety valve can prevent safety problems such as explosion or fire when the internal pressure of the battery is too high. At the same time, there is also a liquid injection hole on the cap. This is a hole for injecting electrolyte when producing lithium batteries. It is also very important for the normal operation of lithium batteries. When docking the lithium battery cap with the lithium battery, in order to provide High welding accuracy and structural strength of the welding generally require the use of laser welding technology. When using laser welding technology to weld lithium battery covers, the lithium battery cap to be used is generally transported to the laser welding table by a conveyor belt during feeding, and the lithium battery cap is generally allowed to automatically fall to the top of the lithium battery under the action of gravity.
