Abstract

The invention belongs to the technical field of battery manufacturing, and relates to an integrated battery cell production and winding machine for online short-circuit detection, including a short-circuit test mechanism, which includes a test installation bracket, a driving cylinder, a guide slide assembly, and a main drive synchronous Wheels, clutches and gears, the test installation bracket includes a pair of linear bearing guide rods set parallel to the cell conveying mechanism, the driving cylinder and the clutch are respectively arranged at both ends of the linear bearing guide rod, and the guide slide assembly is driven by the driving cylinder along the straight line The bearing guide rod is movable, and a rack parallel to the linear bearing guide rod is fixedly connected to the guide slide assembly. The main drive synchronous wheel and the gear are fixed by the shaft perpendicular to the linear bearing guide rod and can be controlled by the clutch to advance and retreat along the axis, so that The gear and rack switch between meshing and non-meshing. The test of the battery cell of this equipment is completed by the short-circuit test probe assembly in synchronous movement, and the battery cell does not need to stop for short-circuit detection, which saves detection time.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to an integrated battery cell sheeting and winding machine that efficiently and fully automatically completes online short-circuit detection for cell manufacturing. Background technique [0002] The battery cell of a cylindrical lithium battery is a hollow cylinder formed by winding a positive electrode sheet, a negative electrode sheet, and two separators. The raw materials of positive electrode sheet, negative electrode sheet and separator are tapes. One positive electrode ear should be welded on the positive electrode sheet, and two negative electrode ears should be welded on the negative electrode sheet. The separator is used to separate the positive electrode sheet and the negative electrode sheet. Four coats of glue are required. In the past, the material tape was often cut first, and then the process of film making and winding was carried out sequentially, resu...
