The invention discloses an electric vehicle lithium battery electrode plate with an automatic welding and locking function. The electric vehicle lithium battery electrode plate comprises plurality ofsingle cell bodies, a shell, a locking device and two positioning assemblies, wherein the plurality of the single cell bodies are positioned in the shell and are stacked together; two outlets are symmetrically formed in one side of the shell; the locking device is fixed on the outer side of the shell; and the two positioning assemblies are symmetrically arranged on the two sides of the shell. According to the electric vehicle lithium battery electrode plate, the plurality of single cell bodies are stacked together and placed in the shell, and tabs on the cell bodies can be effectively clampedand positioned through the locking device, so that subsequent ultrasonic welding treatment can be facilitated; and before welding, by virtue of the positioning assembles, effective positioning can berealized.
Description
technical field [0001] The invention relates to the technical field of electrode sheet locking and welding, in particular to an electrode sheet of an electric vehicle lithium battery with an automatic welding and locking function. Background technique [0002] During the production and processing of lithium batteries, it is necessary to stack multiple electrode sheets into a small battery cell, and then stack multiple small battery cells in parallel to form a large battery cell. At the same time, it is necessary to conduct ultrasonic waves on the ears on the electrode sheet Welding treatment. [0003] At present, when welding the electrode sheet, it is manually positioned by hand, and the welding is carried out by relying on the penetration of employees and their own experience. The safety is low, the labor intensity is high, and the electrode sheet is easy to deviate during the welding process, resulting in weak welding, etc. , for this reason, we propose an electric vehic...
