Abstract

The invention discloses a lithium battery diaphragm tensile strength detection device which comprises a bottom plate, a box body is fixed to the top of the bottom plate, a boss is fixed to the center of the outer wall of the top of the bottom plate, a guide rod is fixed between the outer wall of the left side of the boss and the inner wall of the box body, the guide rod is slidably sleeved with a sliding block, and an extrusion mechanism is fixed to the right side of the sliding block. A clamping mechanism is fixed to the left side of the top of the sliding block, a limiting strip is fixed to the right side of the top of the sliding block, a buffering groove is formed in the top of the limiting strip, and a buffering mechanism is arranged in the buffering groove. The stretching acting force can be buffered through the elasticity of the supporting springs and the guiding effect of the guiding wheels, so that the guiding wheels can apply downward acting force to the supporting springs, and the situation that the speed is too high in the initial stretching process, the pulling strength is too large, and consequently tearing is caused is avoided.

Description

technical field [0001] The invention relates to the technical field of lithium battery diaphragm quality detection equipment, in particular to a lithium battery diaphragm tensile strength detection device. Background technique [0002] In the structure of lithium batteries, the separator is one of the key inner layer components. The performance of the separator determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle and safety performance of the battery. The separator with excellent performance plays an important role in improving the overall performance of the battery. The main function of the separator is to separate the positive and negative electrodes of the battery to prevent short circuit due to contact between the two electrodes, and also has the function of allowing electrolyte ions to pass through. The separator material is non-conductive, and its physical and chemical properties have a great impact on t...
