Lithium battery cap pressure welding device

Abstract

The invention discloses a lithium battery cap pressure welding device. The lithium battery cap pressure welding device structurally comprises a machine case, a control panel, a sealing connecting plate, welding wire pipes, a lifting rod, a welding control machine head, a telescopic rod, a welding head and a battery cap pressing and covering device. The machine case is a cuboid, the control panel is arranged at the front end of the machine case, and the rear portion of the control panel and the front portion of the machine case are buckled and connected through nuts in a locked manner. The sealing connecting plate is welded to the lower right position of the left side of the machine case and electrically connected with the welding wire pipes. One ends of the welding wire pipes are connectedto the left side and the right side of the welding head correspondingly, and the other ends of the welding wire pipes are electrically connected with the machine case through the sealing connecting plate. The lifting rod is arranged at the middle end of the left side of the machine case and arranged on the left side edge of the sealing connecting plate. The lithium battery cap pressure welding device has the beneficial effects that by means of the lithium battery cap pressure welding device, a vertical pressing device can be used for tightly pressing a cap and a pipe shell, the sealing performance is good, the safety quality is improved, manual operation is not needed, cost is reduced, the production efficiency of enterprises is improved, profits are increased, and convenience and practicability are achieved.

Description

technical field [0001] The invention relates to a lithium battery cap pressure welding device, which belongs to the field of battery cap pressure welding devices. Background technique [0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from a rechargeable battery. Lithium-ion batteries are different from lithium-ion polymer batteries. The inventor of the lithium battery is Edison. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronics technology at the end of the 20th century, miniaturized equipment is increasing day by day, which puts forward high requirements for power supply. Lithium batteries have entered a large-scale practical stage. ...
