Abstract

The invention provides a device for measuring the width of a soft package battery, and belongs to the technical field of battery measurement. The device comprises a base, a stop block, a first positioning block, a second positioning block, a toggle clamp, an air cylinder and a width measuring instrument, wherein the base is placed on the horizontal plane, the stop block is fixed to the upper surface of the base, the first positioning block is placed on the upper surface of the base, the first positioning block comprises a transverse block and a first vertical block, the transverse block is vertically arranged at the right end of the first vertical block, a soft package battery is placed on the upper surface of the transverse block, the second positioning block is arranged on the side, awayfrom the stop block, of the first positioning block, the second positioning block comprises a second vertical block and a sliding block, the toggle clamp is fixed to the upper surface of the transverse block, the air cylinder is installed on the upper surface of the base and located at the end, away from the soft package battery, of the second positioning block, and the width measuring instrumentis fixed to the upper surface of the base. The device is simple in structure and convenient to operate, replaces a manual operation mode, and is good in measurement stability and accuracy.

Description

technical field [0001] The invention belongs to the technical field of battery measurement and relates to a device for measuring the width of a pouch battery. Background technique [0002] Soft-pack batteries refer to lithium-ion batteries packaged in aluminum-plastic film. Before the module is assembled, edge folding is required. The sides are not attached to the main body of the battery, but there is a certain pressure on the sides of the aluminum-plastic film when the module is actually used. Therefore, there is a large difference in width between the free state of the battery after folding and the state of use in the module. The current manual vernier caliper measurement method used for battery width, due to manual operation, different measurers use different forces, and there are certain differences in the measured values. At the same time, because the vernier caliper uses two-point positioning to measure the distance between two points, there are differences in the po...
