Puncture test device with protection function for lithium battery manufacturing

Abstract

The invention discloses a puncture test device with a protection function for lithium battery manufacturing, which comprises a base, a cover plate, a fixing frame, a guide disc and a water tank. The base is mounted on a working ground, and a test box is fixed at the top of the base; the cover plate is installed at an opening in the top of the base in a penetrating mode, a motor is fixed to the top of the cover plate through bolts, and a positioning block is arranged at the edge of the bottom of the cover plate; the fixing frame sleeves a reciprocating lead screw in a threaded mode, and a threaded fixing assembly is installed at the bottom of the fixing frame in a penetrating mode; the guide disc is embedded in the side wall of the test box, and one end of a pull rod penetrates through the side wall of the test box and is in shaft connection with a mounting plate; and the water tank is installed on the outer side of the test box, a spray head is connected to the water tank through a pump, and a movable rod is installed on the outer side of the spray head in a sleeving mode. According to the puncture test device with a protection function for lithium battery manufacturing, multi-range spraying is carried out, fire extinguishing protection is carried out in time, meanwhile, fixing and multi-angle puncture test are carried out on a lithium battery, and the test efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to a puncture test device for lithium battery manufacturing with protection function. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or alloy as positive and negative electrode materials and uses non-hydrolytic solution. It is widely used in the use of electric vehicles. In order to ensure the safe use of lithium batteries, a puncture test is required during manufacture. The use of a puncture test device is an existing conventional method. The publication number (CN112763913A) involves a lithium battery puncture and shear test device, including a casing, and the casing is provided with a closed casing cavity... described There is a smoke detection module on the right side of the puncture rod, and the smoke detection module is fixedly arranged at the lower end of the puncture bottom plate to perform puncture and shear ...
