As shown in fig. 4 and fig. 6, in operation, when the pole piece 61 on the unwinding winding drum 6 is insufficient, a new winding drum 6 with sufficient pole piece 61 is mounted on the other clamping assembly 4, at this time, the rotating motor 33 is started, the rotating frame 31 is driven by the rotating motor 33 to rotate, so that the positions of the two clamping assemblies 4 are interchanged, at this time, the pole piece 61 of the old unwinding winding drum 6 passes through the new winding drum 6 and then bypasses the laminating roller 52, and the surface of the new winding drum 6 close to the laminating roller 52 is pasted with the double-sided tape 62; then, starting a cutting motor 532 to enable the attaching roller 52 to move close to the unwinding frame 12, and pressing the pole piece 61 unwound from the old winding cylinder 6 to be adhered to the double-sided tape 62 of the new winding cylinder, so that the pole piece 61 of the new winding cylinder 6 can be connected to the pole piece 61 being unwound; and then the cutter 54 is rotated to cut off the pole piece 61 of the old coil cylinder 6 which is not connected with the new coil cylinder 6, and the coil cylinder 6 wound with enough pole pieces 61 can replace the original coil cylinder 6 to discharge, so that continuous automatic coil change is realized, and the processing efficiency is improved.

The implementation principle of the application is as follows: when the clamping device is used, the screw motor is started to enable the adjusting screw 422 to rotate, and the adjusting screw 422 is in threaded fit with the fixed frame 421 and moves axially, so that the clamping frame 41 connected with the adjusting screw 422 is driven to move transversely; then the material rolling barrel 6 is placed to enable two ends of the material rolling barrel to be respectively aligned to the two chucks 43, the other clamping frame 41 can be pushed to move transversely by starting the telescopic piece 423 until the chucks 43 on the two clamping frames 41 tightly push the material rolling barrel 6, and the material rolling barrel 6 can be clamped and fixed; then, starting the power motor 44, wherein the power motor 44 drives the chucks 43 to rotate, so that the material rolling barrel 6 clamped between the two chucks 43 rotates to be unreeled; in the unreeling process, the position of the unreeling frame 12 is monitored in real time by the first deviation rectifier 24, if the unreeling frame 12 deviates relative to the discharge frame 13, the first deviation rectifier 24 transversely pushes the unreeling frame 12 to integrally move on the base 11 so as to realize deviation correction, the unreeling precision and stability of the pole piece 61 are effectively improved, and the quality of a battery is further ensured.

If the pole piece 61 on the unwinding winding drum 6 is insufficient, a new winding drum 6 with sufficient pole piece 61 is mounted on the other clamping assembly 4, and the double-sided tape 62 is adhered on the surface of the new winding drum 6 close to the attaching roller 52, the rotating motor 33 is started to rotate the rotating frame 31 until the positions of the two clamping assemblies 4 are exchanged, at this time, the pole piece 61 unwound by the old winding drum 6 bypasses the attaching roller 52 after passing through the new winding drum 6, and the double-sided tape 62 is adhered on the surface of the new winding drum 6 close to the attaching roller 52; then, the cutting motor 532 is started to enable the attaching roller 52 to move close to the unwinding frame 12, the attaching roller 52 presses the pole piece 61 unwound from the old winding cylinder 6 to enable the pole piece 61 to be adhered to the double-sided tape 62 of the new winding cylinder, and the pole piece 61 of the new winding cylinder 6 can be connected to the pole piece 61 being unwound; and then the cutter 54 is rotated to cut off the pole piece 61 of the old coil cylinder 6 which is not connected with the new coil cylinder 6, and the coil cylinder 6 wound with enough pole pieces 61 can replace the original coil cylinder 6 to discharge, so that continuous automatic coil change is realized, and the processing efficiency is improved.
