A new energy lithium battery production metal cap stamping processing equipment

Abstract

The invention relates to the technical field of lithium battery production and processing, in particular to a new energy lithium battery production metal cap stamping processing equipment, including a processing table, a smoothing roller, a vertical plate and a winding shaft. The material shifting mechanism designed in the present invention pushes the stamped cap to move to the right along with the remaining material of the aluminum strip, so that the stamped cap falls from the blanking hole into the receiving box, thus avoiding manual removal of the cap from the processing table Under the problem of increasing the labor intensity, the safety of the operator is guaranteed. At the same time, the feeding mechanism is simple and easy to operate. There are tensioning shafts on both sides of the lower mold to tension the aluminum strip, so that the left and right sides of the lower mold A certain amount of aluminum strip is left on both sides to avoid the problem that the stamping head directly deforms or breaks the cap during stamping due to the tight pull of the aluminum strip on the lower mold during the stamping process of the aluminum strip, thereby The production quality and production efficiency of the cap are improved.

Description

technical field [0001] The invention relates to the technical field of production and processing of lithium batteries, in particular to a stamping and processing equipment for producing metal caps of new energy lithium batteries. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and uses non-aqueous electrolyte solution, and is often used in the field of new energy. The lithium battery is composed of a positive electrode, a separator, a negative electrode, an organic electrolyte and a battery shell, and a metal cap is installed at both ends of the lithium battery to connect electricity and protect. Assembled with lithium batteries. [0003] At present, when stamping the cap of lithium battery, one end is loosened and the other end is rolled and pulled to move the aluminum bar. The structure of the existing part of the cap removal mechanism is relatively complicated, which incr...

AI Technical Summary

Problems solved by technology

[0003] At present, when the lithium battery cap is stamped, one end is loosened and the other end is rewound to pull the aluminum strip to move. When the aluminum strip stops moving intermittently, the stamping head and the cap mold are used to punch out the cap from the aluminum strip. At the same time, due to the The structure of the existing part of the cap removal mechanism is relatively complicated, which increases the cost of the equipment. Therefore, in the processing process of some factories, after the cap is formed, the stamped cap is manually removed, and the aluminum bar waste after stamping is removed. Rewinding, but in this way, the following problems will occur in the stamping process of lithium battery production metal caps: 1. After the cap is stamped and formed, the cap is manually removed from the processing table, which increases the labor intensity At the same time, when the cap is removed, the thickness of the aluminum strip and the stamped cap is relatively thin, which is easy to scratch the operator, resulting in the safety of the operator cannot be guaranteed

[0004] 2. Due to the tight pull of the aluminum strip during the stamping process, the stamping head is prone to the problem of stamping deformation or breakage of the cap during stamping, resulting in the production quality of the cap not being guaranteed, and at the same time causing waste of raw materials, and Reduced production efficiency of aluminum strip
