Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery stamping test, in particular to a lithium battery stamping detection device. Background Art

[0002] With the rapid development of portable electronic devices and electric vehicles, the safety and reliability of lithium batteries as the main energy storage devices have attracted widespread attention. Lithium batteries may be subjected to varying degrees of physical impact during production, transportation and use, which may damage the structural integrity and electrochemical performance of the battery and even cause safety accidents.

[0003] Therefore, strict physical impact testing of lithium batteries is an important part of ensuring their safety. The impact test in the prior art is generally an open test platform. There are high safety risks when conducting impact tests, especially when testing high-energy-density lithium batteries. When high-energy-density lithium batteries are subjected to strong impacts, internal short circuits or thermal runaway may occur, causing the battery to heat up rapidly and possibly explode. In addition, the position of the lithium battery usually needs to be manually adjusted, and the test efficiency is low. Utility Model Content

[0018] In the above solution, the choice of transparent explosion-proof glass panels ensures that operators can clearly observe the working conditions inside while preventing possible safety risks caused by accidental explosions. This material provides both visual transparency and necessary safety protection characteristics. The handles installed on the cabinet doors allow operators to easily open and close the cabinet doors, facilitating daily maintenance and equipment operation. The handle design takes into account the comfort and practicality of operation.

[0019] Furthermore, the tray includes a placement plate, three baffles and a front plate are vertically installed on the side of the placement plate, and a handle is installed on the front plate.

The tray is slid away from the test cabinet, the lithium battery is placed in the groove position of the tray, and then the tray is pushed into the test cabinet, so that the lithium battery is just opposite to the positioning opening, and the test punch is driven by the stamping drive member to move in the direction of the positioning opening until the test punch impacts the lithium battery to implement the stamping test of the lithium battery. The test does not require manual adjustment of the position of the lithium battery, which improves the test efficiency. The test punch is located in the test cabinet, so that the impact test is carried out in a closed test cabinet, which is safer. BRIEF DESCRIPTION OF THE DRAWINGS
