Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model.

The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0035] When a defective surface sheet is detected, the coating machine stops working, the working electrode sheet stops moving, the first clamping assembly 21 and the second clamping assembly 22 clamp the working electrode sheet respectively, then the moving assembly 31 drives the mounting plate 32 and the tape cutting assembly 33 to move, so that the tape cutting assembly 33 cuts off the working electrode sheet between the first clamping assembly 21 and the second clamping assembly 22, then the first power member 24 drives the first clamping assembly 21 to rise, so that the first clamping assembly 21 drives the working electrode sheet with the defective surface sheet to rise, so as to form a defective product processing station, and at the same time, the third clamping assembly 23 clamps the workpiece on the winding mechanism 4. The coil head of the defective surface sheet is clamped, and the second power member 25 drives the third clamping assembly 23 to approach the first clamping assembly 21 to align the cut end of the working electrode sheet with the defective surface sheet with one end of the coil head of the defective surface sheet. Then, the moving assembly 31 drives the mounting plate 32 and the gluing assembly 34 to move, so that the gluing assembly 34 sticks the tape between the cut end of the working electrode sheet with the defective surface sheet and one end of the coil head of the defective surface sheet. Finally, the first clamping assembly 21 and the third clamping assembly 23 are released, and the winding mechanism 4 is started, and the winding mechanism 4 winds up the electrode sheet with the defective surface sheet.

[0036] When the electrode of the defective surface sheet is wound up, the first clamping assembly 21 and the third clamping assembly 23 respectively press the electrode, and the moving assembly 31 drives the mounting plate 32 and the cutting assembly 33 to move, so that the cutting assembly 33 cuts off the electrode between the first clamping assembly 21 and the third clamping assembly 23.

Finally, the first clamping assembly 21 and the second clamping assembly 22 are released at the same time, and the coater continues to work, so that the working electrode continues to move, thereby automatically removing the electrode with defective surface in double-sided coating and improving work efficiency.

The support plate 212 is arranged on the top of the fixed plate 211. The first cylinder 214 is arranged on the bottom of the fixed plate 211. The pressing plate 213 is located above the supporting plate 212. The working pole piece moves between the supporting plate 212 and the pressing plate 213. The supporting plate 212 can support the pole piece. The first cylinder 214 is used to drive the pressing plate 213 to move closer to or away from the supporting plate 212 to tighten or loosen the pole piece.

[0040] Specifically, two first cylinders 214 are provided, and the telescopic ends of the two first cylinders 214 are respectively connected to the two ends of the pressure plate 213. The two first cylinders 214 simultaneously drive the pressure plate 213 to move closer to or away from the support plate 212, so that the pressure plate 213 can evenly apply the clamping force on the pole piece to prevent the pole piece from loosening.

[0041] Furthermore, the structures of the second clamping assembly 22 and the third clamping assembly 23 are the same as that of the first clamping assembly 21 .

[0042] Reference Figure 3 When the first power member 24 drives the first clamping assembly 21 to rise, the support plate 212 in the first clamping assembly 21 and the support plate 212 of the third clamping assembly 23 form an upper belt connection platform.

[0043] Reference Figure 2 When the first power member 24 drives the first clamping assembly 21 to descend, the support plate 212 in the first clamping assembly 21 and the support plate 212 of the second clamping assembly 22 form a lower belt connection platform.

[0046] Reference Figure 4 In some preferred embodiments, the number of the second power members 25 is two, and the two second power members 25 are respectively arranged on the outer sides of the two side plates 11.

When the pole piece needs to be cut or glued, the vertical linear module 312 drives the tape cutting component 33 and the gluing component 34 to fall in the vertical direction at the same time, and the tape cutting component 33 or the gluing component 34 approaches the pole piece. Then, the longitudinal linear module 311 drives the tape cutting component 33 and the gluing component 34 to move horizontally at the same time along a direction perpendicular to the conveying direction of the pole piece, thereby achieving cutting or taping of the pole piece.

[0048] Reference Figure 7 and Figure 8 Furthermore, the tape cutting assembly 33 includes a cylinder frame 331, a second cylinder 332 and a first cutter 333. The cylinder frame 331 is arranged on the mounting plate 32, the second cylinder 332 is arranged on the cylinder frame 331, and the first cutter 333 is arranged at the telescopic end of the second cylinder 332. When the tape cutting assembly 33 approaches the pole piece, the telescopic end of the second cylinder 332 extends to drive the first cutter 333 to puncture the pole piece, and then the longitudinal linear module 311 drives the tape cutting assembly 33 to move horizontally along the conveying direction perpendicular to the pole piece, so as to cut the pole piece.

Then, the third cylinder 343 drives the glue sticking roller 342 to stick the tape between the ends of the two pole pieces. 43 extends out to drive the glue roller 342 to stick the tape head between the ends of the two pole pieces, then, the longitudinal linear module 311 drives the glue assembly 34 to move horizontally along the conveying direction perpendicular to the pole pieces, at the same time, the tape unwinding roller 341 unwinds the tape, the fourth cylinder 345 extends out to drive the clamping roller 344 to clamp the tape stuck on the two pole pieces, when the tape is pasted, the fifth cylinder 347 extends out to drive the second cutter 346 to cut the tape, finally, the third cylinder 343, the fourth cylinder 345 and the fifth cylinder 347 retract respectively, waiting for the next gluing action, thereby, automatic gluing can be achieved, and the tape is firmly pasted.

[0050] Furthermore, the glue application assembly 34 also includes a back plate 348, a belt pressing plate 349 and a sixth cylinder 340.

The sixth cylinder 340 is used to drive the belt pressing plate 349 to move closer to or away from the back plate 348 to compress or loosen the tape. When the tape needs to be cut, the sixth cylinder 340 drives the belt pressing plate 349 to move closer to the back plate 348 to compress the tape. The compression roller 344 and the belt pressing plate 349 can compress the tape on both sides of the second cutter 346, so that a section of the tape corresponding to the second cutter 346 has tension, which is convenient for cutting the tape.

[0051] Reference Figure 4 In some preferred embodiments, the winding mechanism 4 includes a servo motor 41, a reducer 42, a coupling 43 and a winding shaft 44.
