Automatic encapsulating machine for bottoms of square lithium-ion battery cells

Abstract

The invention provides an encapsulating machine for the bottoms of square lithium-ion battery cells. The encapsulating machine comprises a rack and a cell discharging and transferring mechanism, a shearing and tape sending mechanism, a sucking disc feeding mechanism for sending the cells to the next step, a rolling mechanism for completing encapsulation, and a control and display mechanism which are arranged on the rack, wherein the cell discharging and transferring mechanism comprises a material tank device, a cell sending movement plate and a feeding cylinder; the shearing and tape sending mechanism comprises a tape pulling cylinder, a cutting device and a tape sending device; the sucking disc feeding mechanism consists of two separate double-sucking-disc devices and a two-way moving tape guide positioning block driven by a cylinder, and the sucking disc vacuumizing is implemented by a vacuum generator; and the rolling mechanism comprises roller wheels and a rolling cylinder. According to the encapsulating machine for the bottoms of the square lithium-ion battery cells, the automatic encapsulation of the cells is realized, the efficiency is high, the consistency is good, and the machine is suitable for multiple models of cells; and for the single-layer coating of the cells, the excess tape thickness is not added, the effective spaces of tapes and the cells are saved, and the cells can conveniently enter shells.

Description

technical field [0001] The invention relates to battery manufacturing equipment, in particular to an automatic rubber wrapping machine for the bottom of a square lithium-ion battery cell. Background technique [0002] At present, lithium-ion batteries are in a period of vigorous development and are widely used in industrial and daily electrical appliances. As the core processing in the manufacturing process, most of them use artificial encapsulation. In the process of encapsulation, under the condition that it can be fully wrapped in place (required by the battery cell), the tape is longer than the battery core, and the tape is wrapped back. In this way, the length of the tape is about 20mm longer than the width of the battery cell, and the glue The thickness of the battery cell is increased by 4 layers of tape thickness, occupying the effective space of the battery, and increasing the difficulty of entering the case in the subsequent process. In addition, the efficiency o...
