Insulation detection device and detection tooling between pole and cover plate of plastic case battery

Abstract

The invention relates to battery testing equipment, in particular to a device for testing insulation between a pole post and a cover plate of a plastic case battery and a testing tooling thereof. The insulation detection device between the plastic case battery pole and the cover plate includes a detection tool, and the detection tool includes more than two cover plate test contacts, and the cover plate test contact has a conductive connection with a test terminal of the resistance test device. connection end. Since the detection tooling of the insulation detection device between the plastic case battery pole and the cover plate includes more than two cover plate test contacts, and the cover plate test contact has a connection end for conductive connection with a test terminal of the resistance test device Therefore, when in use, multiple detection points of the battery cover can be connected to the resistance testing device at the same time through the test tool, so as to complete the test of multiple test points of the battery cover at one time, thereby improving the accuracy of plastic case batteries. The efficiency of insulation detection between pole and cover plate.

Description

technical field [0001] The invention relates to battery testing equipment, in particular to a device for testing insulation between a pole post and a cover plate of a plastic case battery and a testing tooling thereof. Background technique [0002] Plastic case batteries have been widely used in recent years due to their high strength and corrosion resistance. As an important part of the plastic case battery, the electrolyte will inevitably partially remain on the surface of the battery case during the production process of the plastic case battery. When the electrolyte remains on the cover plate of the plastic case battery, the remaining electrolyte will Under special environmental conditions, it is very likely that the insulation performance between the plastic case battery case and the pole will be reduced, resulting in electrification of the plastic case battery case. [0003] In order to avoid the above-mentioned problems, plastic case batteries need to be strictly tes...

Problems solved by technology

[0004] However, in the actual production process, due to the uncertainty of the distribution position of the residual electrolyte on the surface of the cover plate, it is necessary to measure multiple points at different positions during detection to reduce the missed detection rate, and the insulation resistance tester can only detect one point at a time , which has caused the problems of too long detection time and low detection efficiency, which cannot meet the needs of production efficiency
