A battery pressure detection device

Abstract

The invention provides a detection device for battery pressure and belongs to the technical field of battery detection. The detection device for battery pressure comprises a frame, a fixing base, a pressurizing module and a detecting module, wherein a water tank for storing water is arranged on the lower part of the frame; the interior of the fixing base is hollow; the fixing base is fixedly arranged on the frame; the fixing base is used for inserting a to-be-detected battery and causing the lower end of the to-be-detected battery expose on the outer side of the fixing base; the upper end of the to-be-detected battery is closed in the fixing base; a pressurizing hole is formed on a side wall of the to-be-detected battery; the inner wall of the fixing base and the side wall of the to-be-detected battery are encircled and formed into an airtight pressurizing chamber; the pressurizing hole is located in a pressurizing chamber; the pressurizing module is arranged on the frame and is used for pressurizing water in the water tank and then injecting into the pressurizing chamber; the detecting module is electrically connected with the pressurizing module and is used for detecting the burst pressure of the detected battery. The detection device for battery pressure has the advantages of reasonable layout and safe and reliable detection work.

Description

technical field [0001] The invention belongs to the technical field of battery detection and relates to a battery pressure detection device. Background technique [0002] In the battery production line, the produced batteries also need to undergo a pressure test. The battery pressure testing equipment is used to detect the burst pressure of the battery. In the existing workshops, most of the battery pressure detection equipment detects the burst pressure of the battery by impacting the inside of the battery with high-pressure air. Such a structural layout is unreasonable. After the high-pressure air is passed into the battery, any part of the battery may explode. Moreover, battery fragments are easy to splash out of the device, the safety performance is low, and the stability of the high-pressure air detection method is poor, which affects the detection accuracy of the device. [0003] To sum up, in order to solve the structural deficiencies of existing battery pressure tes...
