Abstract

The invention relates to the technical field of lithium battery lamination, and provides a laminator and a lamination method thereof. The lamination method comprises the following steps: A. sequentially laminating a first diaphragm, a negative pole piece and a second diaphragm into an integral body, and continuously feeding to the position between a first rotary manipulator and a second rotary manipulator; B. sucking a positive pole piece from a first sub-locating table to the first diaphragm by using the first manipulator, and sucking the positive pole piece from a second sub-locating table to the second diaphragm by using the second rotary manipulator; and C. rotating the positive pole piece and negative pole piece together with the diaphragms by 360 degrees by a first clamping knife to perform coiling lamination. According to the method, the negative pole piece and the diaphragms connected into the integral body and continuously fed, the 360-degree or 180-degree coiling lamination is performed after the positive pole piece is arranged on the lateral side of the diaphragm, thereby increasing the lamination speed and enhancing the production efficiency and production quality of the laminator.

Description

【Technical field】 [0001] The invention relates to the technical field of lithium battery stacking, in particular to a stacking machine and a stacking method thereof. 【Background technique】 [0002] In the field of lithium-ion battery stacking, the stacking method currently used by the stacking machine is: the stacking table drives the diaphragm to move left and right, and after stacking a negative electrode sheet, it moves to the positive electrode stack, so that the cycle reaches the set number of layers. Then cut off the diaphragm and finish with glue. The lamination speed of the existing method can only be between 1.4-2.0s / pcs according to the size of the pole piece, and it is difficult to achieve a breakthrough in higher efficiency. [0003] In view of this, it is an urgent problem to be solved in this technical field to overcome the defects in the prior art. 【Content of invention】 [0004] The technical problem to be solved by the present invention is to provide a l...
