[0051] Working principle:

[0052] The pole piece unwinding assembly 1 and the flattening roller assembly 2 complete the automatic flattening and unwinding of the pole piece; the pole piece unwinding assembly 1 is fed back by the unwinding deviation correction detection assembly 3 to automatically correct the deviation of the pole piece; after passing through the belt receiving platform assembly 4, the first tension detection assembly 5 and the first tension swing roller assembly 6 are used to detect the real-time tension of the pole piece and adjust the tension, so as to ensure the smoothness of the pole piece; the reinforcing rib front detection assembly 7 cooperates with the reinforcing rib assembly 8 to emboss the pole piece foil area to avoid folding during walking; then the pole piece is corrected by the walking deviation correction assembly 9 and the walking deviation correction detection assembly 10, and the pole piece is cut by the laser length measuring assembly 11 and the laser assembly 12; after the lug forming, the lug air knife dust removal assembly 13 is used to remove dust from the lug, and the A-surface CCD defect detection assembly 14 and the lug CCD size detection assembly 15 are used to detect the surface defects of the pole piece and the lug size of the cylindrical battery process; after the pole piece is dusted and the reverse surface defect is detected by the pole piece brush dust removal assembly 16 and the B-surface CCD defect detection assembly 17, the main drive assembly 18 pulls the pole piece and cuts off the tension and removes the iron by the iron removal assembly 19; then the pole piece is corrected by the secondary walking deviation correction assembly 21 and the secondary walking deviation correction detection assembly 22.

[0053] When the cylindrical battery process is made, the pole piece walking is fed back to the defective labeling assembly 23 according to the front CCD detection, and then the pole piece is wound and smoothed by the winding assembly 24 cooperating with the winding pressure roller assembly 25.

[0054] When the square shell battery process and the gap coating blade battery process are made, the pole piece is detected and adjusted in real time by the second tension swing roller assembly 26 and the second tension detection assembly 27; then the pole piece buffer assembly 28 is used to ensure that the speed of the later piece and the front laser lug forming and walking can be matched synchronously.

[0055] When the square shell battery process is made, the first CCD lug detection positioning assembly 29 takes a picture of the lug to position the V-angle cutting position, and the V-angle cutting mechanism 30 cuts the V-angle; then the second CCD lug detection positioning assembly 31 takes a picture of the lug to position the cutting position, and the cutting and die forming mechanism 32 cuts the lug into pieces.

[0056] When the gap coating blade battery process is made, the pole piece is detected and positioned by the positioning sensor before the cutting and die forming mechanism 32, and the length is walked according to the process requirement, and the die directly forms the lug and cuts the piece in one step.

[0057] After the square case battery process and the blade battery process are sheeted, the pole piece dedusting and iron removing assembly 33 removes dust and iron from the pole piece, then the pole piece is conveyed through the positive assembly conveying belt assembly 34, and the size of the sheeted pole piece is detected through the CCD sheet size detection assembly 35, the belt brush dedusting and cleaning assembly 36 can clean the surface of the belt to ensure that the pole piece size detection is not disturbed; then the transition to the inverted conveying belt assembly 37, according to the size detection, whether the formed pole piece is qualified or not, the qualified product is knocked down through the material knocking assembly 381 into the OK pole piece unloading assembly 382, and the NG product continues to be conveyed and falls into the NG pole piece collecting box 383.

[0058] The above only is the preferred embodiment of the present application, and is not used for limiting the present application, any modification, equivalent replacement and improvement etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
