In this process, the pressing claws that press the pole piece are easy to scratch the pole piece when withdrawing, because the pole piece is very thin, but the pressure claw must press the pole piece tightly so that the stacked pole piece can advance on the stacking table There is no deformation during the process, so it is easy to cause the pole piece to be scratched

Embodiment Construction
[0025] Lamination machine is one of the key equipment for the production of square lithium battery. Generally, it consists of ten mechanisms: feeding mechanism, positive electrode material box, negative electrode material box, positive electrode secondary positioning mechanism, negative electrode secondary positioning mechanism, positive electrode feeding mechanism, negative electrode feeding mechanism, lamination table, glue sticking mechanism, lower material organization. The working principle of the stacking machine is to put the positive and negative pole pieces into the material box, and the unloading device moves left and right to pick up the pole piece in the positive and negative material box, and after secondary positioning, the positive and negative pole pieces are placed on the stack alternately. on stage. The diaphragm unwinds automatically, and the lamination table drives the diaphragm to move back and forth to form a Z-shaped winding. After the lamination is co...

The invention discloses a tableting mechanism and method. The mechanism comprises a first tableting device and a second tableting device, the first tableting device comprises a first drive device, the first drive device comprises a first drive piece, a first connecting block and a first inverted L-shaped slide block; the method comprises the following steps: 1, compressing a pole piece to a first emptying position through a pressing claw of the first tableting device; 2, compressing a pole piece through a pressing claw of the second tableting device; 3, enabling the first drive device of the first tableting device to drive the pressing claw to slightly ascend to a set position; 4, enabling a laminating platform to drive a diaphragm back to the emptying position in the step 1; 5, enabling the first tableting device to move forward to the set position, and enabling the pressing claw of the first tableting device to descend to compress the pole piece. According to the tableting mechanism and the tableting method provided by the invention, the pole piece of a lithium battery is laminated through reciprocating movement, the first drive device is arranged on the tableting mechanism to slightly lift the pressing claw of the laminating device, the pressing claw is not in contact with the pole piece in withdrawal process, the scratch of the pole piece is avoided, and the pole piece of the lithium battery is effectively protected.
Description
technical field [0001] The invention relates to the technical field of lithium battery production and manufacturing, and more specifically, to a tablet pressing mechanism and method. Background technique [0002] The lamination machine is one of the key equipments for the production of square lithium batteries. Its lamination mechanism enables the positive and negative poles of the square lithium battery to be stacked together with a separator in the middle. The number of poles can be set. After the stacking is completed , Laminating and discharging are completed by other mechanisms of the lamination machine. The stacking machine generally consists of ten mechanisms: discharging mechanism, positive electrode material box, negative electrode material box, positive electrode secondary positioning mechanism, negative electrode secondary positioning mechanism, positive electrode feeding mechanism, negative electrode feeding mechanism, lamination table, glue application Institut...
