Problems solved by technology

Since these three processes are currently manually separated and placed on the battery cover, the Al-Ni composite sheet 43 is manually positioned and spot welded, and then ultrasonically welded. The entire process is completed manually, which wastes a lot of manpower and has a high probability of error Large, often resulting in open circuit or short circuit of the finished battery, seriously affecting the quality of lithium-ion batteries

Abstract

The invention provides an automatic welding machine of an aluminum-nickel compound piece of a lithium ion battery cover plate, consisting of a feeding mechanism A, a feeding turnover mechanism B, a turnplate mechanism C, a detection mechanism D, a nickel piece feeding mechanism E, a spot-welding machine F, an ultrasonic welding mechanism G, a banking mechanism H and an automatic control mechanism, wherein the feeding mechanism A, the feeding turnover mechanism B, the turnplate mechanism C and the detection mechanism D are arranged on the tabletop of the automatic welding machine; the nickel piece feeding mechanism E, the spot-welding machine F, the ultesonic welding mechanism G and the banking mechanism H are arranged on the turnplate mechanism C; the aluminum-nickel compound piece is placed on the lithium ion battery cover plate through the feeding mechanism A, the feeding turnover mechanism B, the turnplate mechanism C, the detection mechanism D and the nickel piece feeding mechanism E; and the lithium ion battery cover plate is automatically welded with the aluminum-nickel compound piece through the spot-welding machine F, the ultrasonic welding mechanism G and the banking mechanism H. The invention ensures that the whole process flow realizes the automation, changes the traditional mode for manually finishing miscellaneous work, librates the large amount of labor force, greatly improves the work conditions, greatly increases the yield, greatly reduces the manufacturing cost and simultaneously and effectively ensures the quality of products.

Description

technical field [0001] The invention belongs to the technical field of lithium-ion battery manufacturing, and relates to a lithium-ion battery cover plate processing equipment, in particular to an automatic welding machine for an aluminum-nickel composite sheet of a lithium-ion battery cover plate. Background technique [0002] Existing lithium-ion batteries have positive and negative poles, such as figure 2 As shown, the riveted small boss 42 on the lithium ion battery cover plate 41 is the negative pole, and the lithium ion battery cover plate 41 is the positive pole. The material of the negative electrode is generally copper material, which is easier to weld with the lead wire, while the positive electrode welding lead of the lithium-ion battery cover plate 41 is made of aluminum material, so it is difficult to directly weld with the lead wire. A section of aluminum-nickel composite sheet 43 is welded on the ion battery cover plate 41, one side is aluminum and the other ...
