Abstract

The invention discloses a withstand voltage testing device of a lithium battery shell. The device comprises a vertical block, a transverse block is arranged on the outer side of the vertical block, rubber cushion blocks are arranged at the lower end of the vertical block and the lower end of the transverse block, a first cavity is formed in the transverse block, a sliding plate is slidably connected with the inner wall of the first cavity, an external threaded rod is driven by a motor to rotate, the outer side of an internal thread block slides on the inner wall of a second cavity, and it is guaranteed that connecting plates on the two sides move up and down, so that it is guaranteed that pressure-resistant operation is conducted on any upper and lower positions of the lithium battery shell; a second air cylinder drives a sliding block to slide on a cross rod, meanwhile, the friction force between a first damping block and a second damping block on the two sides and the inner wall of a sliding groove is large, it is guaranteed that the second air cylinder stably moves front and back, and use is convenient; a pressing plate is pulled, so that a first spring is compressed, a lithium battery is placed on the transverse block, then the pressing plate is loosened, the first spring is reset to drive the pressing plate to move towards the inner side, and the position of the lithium battery is fixed.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, in particular to a withstand voltage test device for lithium battery shells. Background technique [0002] Lithium batteries refer to batteries containing lithium (including metal lithium, lithium alloys, lithium ions, and lithium polymers) in the electrochemical system; lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries; lithium metal batteries are usually Non-rechargeable and contains metallic lithium; lithium-ion batteries do not contain metallic lithium and are rechargeable. [0003] The existing pressure test device for lithium battery shells cannot fix lithium batteries of different sizes and heights, and at the same time cannot perform comprehensive pressure-resistant operations on different positions of lithium batteries, which greatly limits the use effect of the device. Contents of the invention [0004] The objec...
