Battery module airtightness test subassembly

Abstract

The invention provides a battery module airtightness test subassembly in the technical field of battery test equipment. The battery module airtightness test subassembly comprises a frame; the at least two roller assembly lines are arranged in the frame side by side, are horizontal to the ground and have the same transmission direction; the at least two anti-expansion mechanisms are arranged at the top end of the interior of the frame and located over the roller assembly lines respectively; the at least four opposite insertion mechanisms are arranged at the top end of the interior of the frame and located on the two sides of one anti-expansion mechanism respectively; the at least two air tightness testers are arranged in the frame; the at least four air tightness plugs are respectively arranged on the opposite insertion mechanisms and are communicated with the air tightness tester; and the industrial personal computer is respectively connected with the roller assembly line, the anti-expansion mechanism, the plug-in mechanism and the air tightness tester. The air tightness testing device has the advantages that the quality, the safety and the efficiency of air tightness testing of the battery module are greatly improved.

Description

technical field [0001] The invention relates to the technical field of battery testing equipment, in particular to a battery module air tightness testing device. Background technique [0002] With the rise and development of new energy sources, lithium batteries, as a green high-energy chemical power source, have the advantages of high energy, high power, and low cost, and have been widely used in the new energy industry. Since the lithium battery will release heat during charging and discharging, in order to ensure the safety of the lithium battery, it is necessary to set up a water-cooled plate to cool the lithium battery. The water-cooled plate and the side plates on both sides are riveted into a U-shaped frame, and the U-shaped frame and The lithium batteries installed inside are combined into a battery module. [0003] In order to ensure the safety of the battery module, the water cooling plate in the battery module needs to be tested for air tightness before leaving t...

Problems solved by technology

For the airtightness test of battery modules, there are traditionally two methods: manual test and semi-automatic test, but there are the following disadvantages: 1. Manual test, not only the test speed is slow, but also the airtight plug is manually plugged and unplugged, which is difficult to judge whether In place; 2. The semi-automatic test operation is complicated and cumbersome, and it is easy to cause danger by misoperation; 3. Only one battery module can be tested at a time, which is inefficient
