Abstract

The invention discloses power battery ultrasonic welding equipment. The power battery ultrasonic welding equipment comprises a working table, a tray feeding assembly, a cell feeding assembly, a connecting link feeding assembly, a film-pasting assembly, a cell discharging assembly, a protecting plate feeding assembly, an ultrasonic welding assembly, an electric resistance welding assembly and pressing plate pick-and-place assemblies, wherein the tray feeding assembly, the cell feeding assembly, the connecting link feeding assembly and the film-pasting assembly are arranged on the working table, the tray feeding assembly is used for feeding trays, and the cell feeding assembly is used for positioning cells; the connecting link feeding assembly is used for feeding copper and aluminum connecting links into fixtures, the film-pasting assembly is used for pasting blue glue on the welding area, and the cell discharging assembly is used for outputting the cells pasted with the film; and the protecting plate feeding assembly used for feeding protecting plates, the ultrasonic welding assembly used for compressing and welding positioned lugs, connecting links and protecting plates, the electric resistance welding assembly used for carrying out repair-welding on ultrasonically welded copper poles, and the pressing plate pick-and-place assemblies which are symmetrically arranged on the two sides of a return line body, and are used for transferring pressing plates into the fixtures or disassembling the pressing plates are arranged on the periphery of the return line body. According to the power battery ultrasonic welding equipment, the technical problems that the degree of welding automation of an existing power battery is not high, the manufacturing efficiency, the welding precision and the yield are low, and the manufacturing cost and the failure rate are high are solved; and the power battery ultrasonic welding equipment has the characteristics that the implementation is easy and the stability is high.

Description

【Technical field】 [0001] The invention relates to the technical field of ultrasonic welding, in particular to an ultrasonic welding device for power batteries. 【Background technique】 [0002] Lithium-ion power battery has become the green battery with the best comprehensive performance in the world because of its characteristics of high voltage, high capacity, low consumption, no memory effect, no pollution, small size, low internal resistance, low self-discharge, and many cycles. . It is widely used in many civil and military fields such as new energy vehicles, mobile phones, notebook computers, and tablet computers. Lithium-ion power batteries usually consist of three parts: battery cells, protection circuits and casings. The shell is divided into shell, cover plate, tab and copper / aluminum adapter piece. During the manufacturing process of the power battery, the positioned copper / aluminum adapters, tabs and gaskets need to be welded together on the battery cell. The...
