Problems solved by technology

[0002] The battery peripheral welding process is an important link in the production of lithium-ion power batteries, and the peripheral welding strength inspection is an important method to test the reliability of the peripheral welding. If the peripheral welding strength inspection fails, it means that there are blisters in the peripheral welding or the welding strength is low, which may easily lead to battery leakage. Liquid, battery swelling and other serious problems, these problems will directly affect the subsequent inconvenience and performance degradation of lithium-ion power batteries
[0003] In the prior art, the battery strength testing equipment has poor adaptability, cannot clamp and test battery cases of different shapes, and has poor fixing stability, which affects the test results; in the prior art, the battery strength testing equipment is tested by manual hand-held testing equipment, The labor intensity is high, so a battery case strength testing equipment for lithium battery production is needed to solve the above problems

Abstract

The invention provides battery case strength detection equipment used for lithium battery production. The battery case strength detection equipment comprises an operating table, a box, a clamping component and a detection adjustment component. The box is fixed on the upper end surface of the operating table. The clamping component is installed in the box. The clamping component comprises supporting rods, connecting cylinders, a moving clamp plate, a first clamping boss, a rolling ball nut holder, a lead screw, a moving groove, a fixed clamp plate, a second clamping boss, clamp grooves, clamp blocks, first slide grooves, through holes, pull rods and second slide grooves. The detection adjustment component is arranged on the right side of the box, and the detection adjustment component is installed on the upper end surface of the operating table. The detection adjustment component comprises an electric elevating column, a carrying frame, a cavity, a gear, a rack and a carrying plate. Compared with the equipment in the prior art, the battery case strength detection equipment has the following beneficial effects that fixing of different shapes of battery cases to be detected can be realized so that the adaptability is high and the fixing stability is excellent; and adjustment of the detection position can also be realized so that the work intensity can be reduced and the detectionefficiency is high.

Description

technical field [0001] The invention relates to a battery casing strength detection device for lithium battery production, which belongs to the field of lithium battery production equipment. Background technique [0002] The battery peripheral welding process is an important link in the production of lithium-ion power batteries, and the peripheral welding strength inspection is an important method to test the reliability of the peripheral welding. If the peripheral welding strength inspection fails, it means that there are blisters in the peripheral welding or the welding strength is low, which may easily lead to battery leakage. Liquid, battery swelling and other serious problems, these problems will directly affect the inconvenience of subsequent use and performance degradation of lithium-ion power batteries. [0003] In the prior art, the battery strength testing equipment has poor adaptability, cannot clamp and test battery cases of different shapes, and has poor fixing ...
