the color sensing device 102 is arranged on one side of the arc-shaped part 1012 of the inflatable shaft 101, and comprises a plurality of color sensors 1021, and the color sensors 1021 correspond to the inflatable parts 1011 one by one;
and the controller 111 is electrically connected with the color sensor 1021 and the inflating device 110, and when the color sensor 1021 detects the foil retention area 201 of the pole piece 200, the controller 111 controls the inflating device 110 to inflate the inflatable shaft 101 so that the inflatable part 1011 jacks up the corresponding foil retention area 201.
The pole piece processing mechanism 1 is formed by an inflatable shaft 101, a color sensing device 102 and a controller 111, wherein the inflatable shaft 101 is provided with an arc-shaped part 1012 abutted against a pole piece 200, the pole piece 200 is laid on the arc-shaped part 1012 and can move relative to the inflatable shaft 101, a plurality of inflatable parts 1011 are arranged at intervals along the length direction of the arc-shaped part 1012, the inflatable shaft 101 is connected with an inflating device 110, and the inflatable parts 1011 can be protruded outwards when the inflating device 110 inflates the inflatable shaft 101; the color sensing device 102 is arranged on one side of the arc-shaped part 1012 of the inflatable shaft 101, the color sensing device 102 comprises a plurality of color sensors 1021, and the color sensors 1021 and the inflatable part 1011 have a one-to-one corresponding connection relationship; and the controller 111 is electrically connected to the color sensor 1021 and the inflator 110.

5. The pole piece processing mechanism of claim 4, wherein the limit sensor is further connected with a driving device, the driving device is electrically connected with the controller, and the driving device is used for driving the limit sensor to move on the guide rail.
6. The pole piece processing mechanism according to claim 5, wherein a pole piece material identification device is further disposed on the connection rod, the pole piece identification device is electrically connected to the controller, and an extension value corresponding to the material of the pole piece is preset in the controller, so that the driving device drives the limit sensor to move to a position on the guide rail corresponding to the extension value when the pole piece identification device identifies the material of the pole piece.
7. The pole piece handling mechanism of claim 1, further comprising position adjustment assemblies disposed at opposite ends of the inflatable shaft, the position adjustment assemblies being electrically connected to the controller to enable relative movement of the inflatable shaft perpendicular to the direction of movement of the pole piece when the color sensing device does not detect the foil retention region.
8. The pole piece processing mechanism according to claim 7, further comprising a base fixedly arranged, wherein the base is provided with a through hole, two ends of the air expansion shaft are provided with a threaded structure, the threaded structure penetrates through the through hole to be connected with the position adjusting assembly, the position adjusting assembly is any one of a stepping motor and a manual rocker, and an output shaft of the stepping motor or the manual rocker is concavely provided with a threaded hole corresponding to the threaded structure.
9. The pole piece handling mechanism of claim 1, wherein the surface of the inflatable shaft is coated with a smooth finish.
10. A pole piece rolling machine is characterized by comprising a pole piece rolling main body, a winding mechanism and the pole piece processing mechanism of any one of claims 1 to 9, wherein the pole piece rolling main body is used for rolling the pole piece, the winding mechanism is used for winding the pole piece, and the pole piece processing mechanism is arranged between the pole piece rolling main body and the winding mechanism.
