Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and particularly relates to an automatic detection device for battery cap height and resistance value. Background Art

[0002] A battery is a device that converts chemical energy into electrical energy. It is mainly composed of three parts: a shell, a battery cell, and a cap. The battery cap is an important structure used to seal the battery and provide a safety valve. During the use of the battery cap, the cap height and resistance are important factors. If the cap height is too high, the safety valve will be shortened too small, the exhaust pressure will be low, and the battery will be easily ignited. If the cap height is too low, the safety valve will be shortened too much, the exhaust pressure will be high, and the battery will be easily ruptured and exploded. The resistance directly affects the current conduction efficiency of the cap. Therefore, during the production and processing of the battery cap, it is usually necessary to test its height and resistance.

[0003] The existing document with the announcement number CN116786467B discloses an automatic test device for the height and resistance of a battery cap, which includes a vibration plate, a stand body provided on one side of the vibration plate, a rotating plate frame provided on the stand body, a height detection mechanism and a resistance detection mechanism installed on the stand body, an A discharge pipe, a B discharge pipe, a C discharge pipe, a D discharge pipe and an E discharge pipe are sequentially provided in a ring shape on the rotating plate frame, and an air blowing mechanism is also provided on the rotating plate frame;

[0004] However, it still has the following disadvantages in actual use:

[0005] The above-mentioned automatic test equipment for the height and resistance of battery caps detects the height of the battery caps on the rotating disk rack through a height detection mechanism. However, during the process, only one cap can be detected at a time, and the detection efficiency is poor.

[0006] The above-mentioned automatic test equipment for height and resistance of battery caps detects the height of the battery caps on the rotating disk rack through a height detection mechanism, and detects the resistance of the battery caps on the rotating disk rack through a resistance detection mechanism. However, in the process, it lacks a structure for cleaning the caps. Since the dust on the battery caps affects the height and resistance detection structures, the accuracy is poor.

[0007] To this end, we provide a battery cap height and resistance automatic detection equipment to solve the above problems. Utility Model Content
