[0003] The cap plays an important component in the existing lithium battery, and the pressure welding between the top cover and the bottom cover in the cap is an important processing procedure. The existing processing method needs to manually place the cap on the pressure welding The bottom end of the pressure welder is manually discharged after welding, which has low safety performance, is easy to injure the operator, and has low production efficiency. The operator's fingers will bring sweat and dust into the cap, which will seriously affect the product quality.

The invention discloses a cap pressure-welding device used for lithium battery production. The cap pressure-welding device used for lithium battery production comprises a workbench and a mounting frame. A sliding rail is arranged at the upper end of the inner side of the mounting frame. A plurality of sliding blocks are arranged on the surface of the sliding rail. A wavy extrusion block is arranged on one side of the sliding blocks. A rack is arranged on one side of the wavy extrusion block. A gear is arranged on one side of the rack. A second rotary shaft is arranged on one side of the gear.A rotary motor is arranged on one side of the second rotary shaft. A first belt wheel is arranged on one side of the rotary motor. A belt is arranged on one side of the first belt wheel. A second beltwheel is arranged on one side of the belt. A first rotary shaft is arranged on one side of the second belt wheel. An indirect extrusion wheel is arranged on the surface of the first rotary shaft. Byadoption of the cap pressure-welding device used for lithium battery production, caps in a cap storage cylinder can be continuously pushed into a pressure-welding channel so as to be welded under pressure, so that automatic pressure-welding is achieved, manual operation is not needed, and the safety and pressure-welding efficiency are improved.
Description
technical field [0001] The invention relates to a pressure welding device, in particular to a cap pressure welding device for lithium battery production. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. 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 science and technology, lithium batteries have become the mainstream now. [0003] The cap plays an important component in the existing lithium battery, and the pressure welding between the top cover and the bottom cover in the cap is an important processing procedure. The existing processing method needs to manually place the cap on the pressure welding The bottom end of the press welder is manuall...
