The diaphragm separation placement table 4 is provided with a number of avoidance gaps 41 adapted to the diaphragm clamping jaws, and one of the avoidance gaps 41 is provided with a diaphragm sensor 42. When the diaphragm sensor 42 senses the double-layer diaphragm 1a, the diaphragm clamping jaws clamp the double-layer diaphragm 1a and pull the double-layer diaphragm 1a in conjunction with the rewinding release speed of the rewinding robot assembly 5; since the battery rewinding layers are pre-processed by manual labor or equipment, the outermost double-layer diaphragm 1a is first peeled off, so that the separation air knife 32 can blow out the double-layer diaphragm 1a smoothly, while the positive electrode core 2a is still adhered to the battery, so that the battery rewinding robot needs to rotate the battery 90 degrees when clamping the battery, and then align the positive electrode core 2a with the core scraper 33 and move it downward, so that the core scraper can also smoothly separate the outermost positive electrode core 2a from the battery.

[0021] In this embodiment, the battery rewinding robot assembly 5 includes a rewinding transverse shifter 51, a rewinding elevator 52 arranged on the rewinding transverse shifter 51 and a rewinding clamping claw assembly 53 arranged on the rewinding elevator 52, the rewinding clamping claw assembly 53 includes a rewinding connecting plate 531 connected to the rewinding elevator 52, the lower end of the rewinding connecting plate 531 is symmetrically provided with a rewinding moving guide rail 532, a clamping claw moving pulley group 533 is provided between the two rewinding moving guide rails 532, and a clamping claw module is provided at both ends between the two rewinding moving guide rails 532, and the clamping claw module is provided with a belt clamping block 534 fixed to the belt of the clamping claw moving pulley group 533, and the clamping claw module includes a clamping claw longitudinal arm 535, and the upper end of the clamping claw longitudinal arm 535 is provided with a rewinding driving motor.

[0022] In this embodiment, a battery loading conveyor line 6 is provided on one side of the base 1, and an incoming material sensor 7 is provided on the battery loading conveyor line 6. A battery loading robot 8 is provided between the battery loading conveyor line 6 and the carrier 2, and the battery loading robot 8 is used to clamp the battery and move it to be placed in the carrier 2; the battery loading robot 8 includes a loading bracket 81, a loading transverse movement mechanism 82 provided on the loading bracket 81, a loading lifting mechanism 83 provided on the loading transverse movement mechanism 82, a rotating mechanism provided on the loading lifting mechanism 83 and a clamp mounting plate 84 fixed to the rotating mechanism, a clamp cylinder is provided on the upper end of the clamp mounting plate 84, and a loading clamp arm 85 is provided at both ends of the clamp cylinder, and the loading clamp arm 85 is provided with a flipper, and the flipper is connected to the battery clamp, and the clamp mounting plate A CCD camera is provided at the lower middle end of 84; after the battery is wound, the outermost layer of material will be placed on the left end of the battery to form a winding boundary line 3a. In order to ensure that the separation air knife 32 can blow out the double-layer diaphragm 1a, it is necessary to ensure that when the battery is loaded onto the carrier 2, the winding boundary line 3a is also at the left end of the battery. Therefore, it is necessary to ensure that the direction of battery loading is also guaranteed, but manual loading may be placed in the wrong direction. Therefore, when the battery loading robot 8 clamps the battery, the position of the winding boundary line 3a is first photographed by the CCD camera. If it cannot be photographed, it proves that the back of the battery is placed upside down, and the flipper is required to drive the loading clamp arm 85 to flip 180°, turn the battery front side up, and then photograph it. If the winding boundary line 3a is at the right end of the battery, the rotating mechanism drives the loading clamp arm 85 to rotate 180° so that the winding boundary line 3a of the battery is at the left end of the battery.
