The invention relates to the technical field of a battery production device, and provides a pole piece reject removing device. The pole piece reject removing device comprises a pole piece unreeling component, a reject removing component, a reject pole piece rolling component, a qualified pole piece rolling component and a substrate; the reject removing component comprises a reject detection module, a cutting module, a good-product and reject switching platform and an adhesive tape affixing module, wherein the reject detection module is used for detecting a reject pole piece in the pole pieces and a head part of the qualified pole piece; the cutting module comprises a cut-off knife for cutting off the pole piece; the good-product and reject switching platform is provided with a first mechanical hand and a second mechanical hand, the first mechanical hand is used for clamping and moving the qualified pole piece, and the second mechanical hand is used for clamping and moving the reject pole piece; the adhesive tape affixing module is used for affixing an adhesive tape on the cut-off pole piece so as to connect the cut-off pole piece and the pole piece on the rolling component. The reject pole piece caused by a previous step of the rolling step is removed and the qualified pole piece is rolled, so that the waste of diaphragm caused by the subsequent rolling step in the rolling process can be reduced.
Description
【Technical field】 [0001] The invention relates to the technical field of battery production equipment, in particular to a device for removing defective pole pieces and a lithium battery production machine. 【Background technique】 [0002] After coating, slitting, and welding the tabs, the positive and negative electrodes of lithium batteries enter the winding process, and the positive and negative electrodes and separators are wound into batteries on the winding machine. [0003] In the prior art, the winding machine is equipped with a defective pole piece identification mechanism, and the identified bad pole pieces are wound together with the diaphragm and removed during the winding process. Due to the special structure of the winding machine, the defective pole piece and the diaphragm can only be removed together, resulting in waste of the diaphragm. [0004] In view of this, it is an urgent problem to be solved in this technical field to overcome the defects in the prior ...
