Abstract

The invention discloses a glue folding device, which comprises a mounting frame, an end face glue folding device, a side glue folding device and a first driving device, wherein the end face glue folding device is used for extruding glue films at the two ends of a battery core; the shapes of grooves in a first imitation block and a second imitation block are matched with the shape of the end face of the battery core, the glue films of the battery core end faces with different shapes can be subjected to extruding formation only by changing the imitation block with the shape matched with that of the battery core end face; the side glue folding device is used for extruding the glue film on the side of the battery core; and when the side glue folding device moves to the edge of the side of the battery core, a first torsional spring and a second torsional spring release torsional forces, so that an upper pressing roller and a lower pressing roller move oppositely along the side of the battery core, the movement tracks of the upper pressing roller and the lower pressing roller are the shape of the side of the battery core, and the glue film and the side of the battery core can be adhered effectively.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a folding device. Background technique [0002] The production of battery cells generally adopts two methods: winding and lamination. With the increase in demand for power batteries and quality requirements, the requirements for winding equipment are also getting higher and higher, and the end of the winding equipment has always been a technical difficulty. The cells are unraveled after being wound and formed. [0003] The battery cell folding device in the prior art is suitable for cells with a 90° rear folding angle. For cells with an arc structure at the tail, that is, a battery cell with a non-90° rear folding angle, the adhesive film cannot be completely covered, which affects the performance of the cells. Production quality. [0004] Therefore, how to improve the versatility of the folding device has become an urgent technical problem to be solved by t...
