Automatic tape-sticking, bending and holder-buckling device for power battery

Abstract

The invention discloses an automatic tape-sticking, bending and holder-buckling device for a power battery. The device comprises a rotary table, wherein multiple sets of battery cell fixtures are arranged on an edge of the rotary table; a battery cell feeding unit, a negative electrode tab tape-sticking unit, a positive electrode tab tape-sticking unit, a poor tape-sticking detection unit, a tab bending unit, a lower holder buckling unit, an upper holder buckling unit and a battery cell unloading unit are arranged along the periphery of the rotary table sequentially; a battery cell feeding pulling belt and a battery cell feeding manipulator for transferring battery cells on the battery cell feeding pull belt to the battery cell fixtures of the rotary table are arranged on the battery cell feeding unit; a battery cell unloading pull belt, an NG cache pull belt and a battery cell unloading manipulator for transferring the battery cells from the rotary table to the battery cell unloading pull belt or the NG cache pull belt are arranged on the battery cell unloading unit. The device provided by the invention realize full automation of tape-sticking, bending and holder-buckling for the power battery, reduces influence of human factors, ensures the battery cell tape-sticking, bending and holder-buckling quality, and improves production efficiency of the power battery.

Description

technical field [0001] The invention relates to the technology in the field of power battery production equipment, in particular to a power battery automatic glue sticking, bending, buckling and holding frame device. Background technique [0002] After the ultrasonic welding of the power battery cell tab and the battery cover plate is completed, the upper and lower welding marks of the cell tab need to be protected by flattening. At the same time, because the tab material is soft, if there is no object support, the cell will The shell moves back and forth along the installation direction, which will easily cause the contact and collision between the tab and the battery shell or battery cover, resulting in damage to the tab, unstable discharge process or short circuit. Buckle the cage between them, and before buckling the cage, the root of the lug and the soft connection root of the cover plate need to be bent at a certain angle. In the existing technology, each process is g...

[0002] After the ultrasonic welding of the power battery cell tab and the battery cover plate is completed, the upper and lower welding marks of the cell tab need to be protected by flattening. At the same time, because the tab material is soft, if there is no object support, the cell will The shell moves back and forth along the installation direction, which will easily cause the contact and collision between the tab and the battery shell or battery cover, resulting in damage to the tab, unstable discharge process or short circuit. Buckle the cage between them, and before buckling the cage, the root of the lug and the root of the flexible connection of the cover plate need to be bent at a certain angle

In the existing technology, each process is generally carried out separately, and manual operation is mainly used for gluing, which consumes a lot of human resources, low production capacity, and high production costs. In addition, the batteries are inevitably touched by workers when they are manually operated. It is easy to leave sweat and other pollutants on the battery cells, which is easy to cause quality problems; and the existing mechanical equipment is not highly automatic, resulting in poor consistency and stability of battery quality, low yield rate, and the need to stop for refueling. Affect production efficiency, production cost is too high
