Embodiment Construction
[0032] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0033] Such as Figure 1-Figure 4 As shown, the pole piece deviation correction device provided by the present invention includes a driving roller, a pinch roller 210 , a clutch mechanism 120 , a first driving mechanism 220 , a second driving mechanism 130 and a third driving mechanism 310 .
[0034] The driving roller and the clamping roller 210 are arranged in parallel, and the first driving mechanism 220 can drive the clamping roller 210 so that the clamping roller 210 approaches or moves away from the driving roller....

The invention provides a pole piece deviation correction device and lithium battery winding equipment, which relate to the technical field of lithium battery automatic winding equipment, including a driving roller, a clamping roller, a clutch mechanism, a first driving mechanism, a second driving mechanism and a third driving mechanism. The driving mechanism; the driving roller and the clamping roller are arranged in parallel; the second driving mechanism is connected with the driving roller through the clutch mechanism; the third driving mechanism can drive the driving roller, the clamping roller and the pole piece along the direction perpendicular to the pole piece in the plane of the pole piece The movement direction moves, the first driving mechanism drives the clamping roller close to the driving roller for clamping the pole piece, the clutch mechanism engages, and the second driving mechanism can drive the driving roller to rotate so that the pole piece enters the piece; when the pole piece is fed into the piece, The clutch mechanism is separated, and the rotation of the winding needle is used to drive the pole piece to be wound. The third drive can drive the pole piece between the clamping roller and the driving roller to move along the width direction of the pole piece, and correct the deviation in the whole process of film feeding and winding. , to improve the alignment accuracy of the pole piece winding.
Description
technical field [0001] The invention relates to the technical field of lithium battery automatic winding equipment, in particular to a pole piece deviation correction device and lithium battery winding equipment. Background technique [0002] Lithium battery winding machine can generally be used for lithium-ion battery cell winding, suitable for oily pole pieces, water-based pole pieces and various separators. The existing production mode can be selected by the entry method of the pole piece, including the positive pole piece first and then the negative pole piece, the negative pole piece first and then the positive pole piece, the positive and negative pole pieces at the same time, and the outsourcing end method, etc. The goal is to strive for Stable operation, convenient debugging and simple operation. The alignment between pole piece and pole piece, pole piece and diaphragm is directly related to the cell yield and finished product quality. [0003] Due to the space lay...
