Abutting the head of the cell 310 , and sticking the cut fixing glue 200 to the welding tab 320 position, the bending driving cylinder 515 pushes the bending glue block 5121 to rotate 90 degrees around the axis of the chute 5111 to the horizontal direction and abuts the lower surface of the battery core 310 , bends the fixing glue 200 and sticks it to the corner of the head of the battery core 310 place.

The automatic bending and gluing machine 100 of the utility model can be bent and glued in place for soft-packed lithium batteries of different thicknesses and sizes at one time, the glue is firmly glued, and the qualified rate of products is improved.

The beneficial technical effect of the utility model is as follows: the fixed glue pressed at both ends is cut off by a blade, so as to ensure that the cut surface of the fixed glue is uniform, and the two glue blocks simultaneously absorb the cut fixed glue and bend the fixed glue 90 degrees to stick it On the tabs and cells, the tabs can be effectively fixed to ensure the parallelism of the tabs, improve production efficiency, and reduce costs. At the same time, it can also be bent and glued for cells of different sizes at one time, with strong versatility.

The above disclosures are only the preferred embodiments of the present invention, which cannot limit the scope of protection of the present invention. Therefore, the equivalent changes made according to the scope of the patent application of the present invention are still within the scope of the present invention. .
