Automatic turnover device for welding cylindrical lithium ion battery cap assembly

Abstract

The invention discloses an automatic turnover device for welding a cylindrical lithium ion battery cap assembly. The automatic turnover device comprises a base, a translation block, a translation driving device, a supporting vertical frame, a lifting block, and a lifting driving device; wherein the translation block is arranged on the base through a horizontal guide mechanism; the translation driving device is connected with the translation block and drives the translation block to move forwards and backwards along the horizontal guide mechanism; the supporting vertical frame is fixed on the horizontal moving block; a lifting block is arranged on the supporting vertical frame through a longitudinal guide mechanism; the lifting driving device is connected with the lifting block and drives the lifting block to move up and down along the longitudinal guide mechanism; the lifting block is provided with a rotary driving device; and the rotary driving device is connected with an elastic chuck driven by the rotary driving device to rotate. The turnover of the battery cap assembly between two welding can be implemented by the automatic turnover device instead of workers, so that the assembly efficiency of a battery cap is greatly improved by matching with an assembly line, the labor intensity of the workers is reduced, and the labor cost is reduced.

Description

technical field [0001] The invention relates to an automatic turning device for welding a cap assembly of a cylindrical lithium ion battery. Background technique [0002] It is generally known in the industry that the cap is the core component of the cylindrical lithium-ion battery, which is related to the safety of the cylindrical lithium-ion battery. At present, the caps of cylindrical lithium-ion batteries widely sold on the market are usually composed of explosion-proof plate 1, top cover 2, orifice plate 3 (aluminum plate), orifice plate gasket 4 and sealing ring 5. The details are as follows: figure 2 As shown, the assembly relationship of these five components is: the top cover 2 is welded and fixed on the top surface of the explosion-proof disk 1, the orifice gasket 4 is placed on the bottom surface of the explosion-proof disk 1, the orifice plate 3 is placed on the orifice gasket 4 and connected with the explosion-proof disk 1, the bottom surface is welded, and the...

Problems solved by technology

[0004] However, at present, there is no special automation equipment for the above-mentioned turning process in the industry, and it is mainly done manually. The disadvantages of manual work are obvious, such as low efficiency, high labor intensity, and high misoperation rate, resulting in a decline in product yield.

Some companies often design an assembly line with automatic feeding and welding for the two welding of components, but there is a manual turning link in the middle, which will obviously reduce the smoothness of production and greatly hinder the company's research and development of the integrated assembly line for battery caps and design progress
