Abstract

The invention provides a laminated device and a laminated device thereof. The laminated device includes: a rotating part, which is rotatably arranged around its own axis and along a predetermined rotating direction, and a plurality of laminated stages are arranged on the rotating part , a plurality of stacking stages are arranged sequentially around the rotation axis of the rotating part; at least one group of feeding assemblies, each group of feeding assemblies includes a first diaphragm feeding mechanism, a first pole piece feeding mechanism, The second diaphragm feeding mechanism and the second pole piece feeding mechanism are used to make multiple stacking stages pass through each feeding mechanism in sequence by rotating the rotating part, so as to load the corresponding stacking stages. The stacking device of the present invention solves the problem of low stacking efficiency of the cell pole pieces of the lithium-ion battery in the prior art.

Description

technical field [0001] The invention relates to the field of lithium battery manufacturing. Specifically, it relates to a lamination device and lamination equipment having the same. Background technique [0002] At present, lithium-ion batteries mostly use stacked cells. The cell pole piece is composed of a positive pole piece, a diaphragm and a negative pole piece. The stacking table drives the diaphragm to move left and right, and then moves to the positive pole Carry out lamination, and stack up to the set number of layers in this way, then cut off the diaphragm, and finish the glue. [0003] However, in the actual production process, the efficiency of the stacking table to perform the stacking action is mostly about 1 second per piece, and the battery electrode sheet is composed of several positive electrode sheets and negative electrode sheets. The preparation process is relatively complicated and requires It takes a lot of time and energy to perform the sequential st...
