The rotation of the screw rod 17 can drive the positioning frame 18 and the positioning rod 19 to move. The threads at both ends of the screw rod 17 are in opposite directions, so as to adjust the distance between the positioning rods 19 on both sides, and rely on the positioning rods 19 to limit the transportation of the pole piece, thereby reducing the displacement of the pole piece during transportation, which is beneficial to improve the cutting accuracy.

[0026] Further, such as Figure 4 As shown, a pair of the connecting plates 32 are slidably connected with brackets 41; the connecting plates 32 are U-shaped; a collecting box 42 is fixedly connected to the bottom of the bracket 41; the collecting box 42 is located at the bottom of the cleaning cotton 33; the pair of collecting boxes 42 are symmetrically arranged; a return spring is fixedly connected between the middle of the bracket 41 and the connecting plate 32; a trapezoidal plate 43 is fixedly connected to the bottom side of the fixing plate 14 at the corresponding position of the bracket 41; when in use, when the cutting knife 15 moves upward, the trapezoidal plate 43 is separated from the top of the bracket 41, and then the return spring will drive the bracket 41 and the collecting box 42 to approach each other, so that the collecting box 42 moves to the bottom of the cotton block, so that the cleaned powder and debris can be collected to reduce the adhesion of these foreign objects to the workbench 11 and the battery electrode. In the process of the cutting knife 15 moving downward, the trapezoidal plate 43 will contact with the top of the bracket 41, and push the two collecting boxes 42 away from each other under the extrusion effect, and the two collecting boxes 42 are separated, so that the cutting knife 15 can cut downward normally.
[0027] Further, such as Figure 2 and 3As shown, a pair of first guide rods 51 are fixedly connected to the bottom side of the workbench 11; the first guide rods 51 penetrate the positioning frame 18 and are slidably connected thereto; a pair of second guide rods 52 are fixedly connected to the top side of the workbench 11; the second guide rods 52 penetrate the fixed plate 14 and are slidably connected thereto; when in use, the positioning frame 18 can be positioned and guided by means of the first guide rods 51 to improve its stability, and the cutting knife 15 can be positioned and guided by means of the second guide rods 52 to improve the cutting accuracy of the cutting knife 15.

[0029] Further, such as Figure 3 As shown, the bottom end of the fixing rod 22 is rotatably connected with a pressing wheel 7; when in use, the pressing wheel 7 is provided to reduce the friction between the bottom end of the fixing rod 22 and the battery electrode, thereby reducing the wear of the fixing rod 22.
[0030] Working principle: When in use, in the current prior art, a conveying roller driven by a motor is installed on the workbench 11, which relies on the rotation of the conveying roller to move and convey the battery pole piece, and then relies on the movement of the cylinder 13 to drive the cutting knife 15 to move up and down, so as to cut the battery pole piece. Before use, the present application relies on the servo motor 16 to drive the screw rod 17 to rotate. The rotation of the screw rod 17 can drive the positioning frame 18 and the positioning rod 19 to move.

The phenomenon of displacement of the electrode piece during the pressing process is beneficial to improve the cutting accuracy. When in use, the cutting knife 15 moves downward, and its fixing plate 14 drives the fixing rod 22 to move downward.

The support rod 31 and the connecting plate 32 are used to fix the cleaning cotton 33, and the cleaning cotton 33 can be used to fix the cutting The cutting knife 15 is wiped, thereby cleaning the powder and debris adhered by the cutting knife 15 for a long time, reducing the foreign matter adhered to the cutting knife 15. When the cutting knife 15 moves upward, the trapezoidal plate 43 separates from the top of the bracket 41, and then the return spring drives the bracket 41 and the collecting box 42 to move closer to each other, so that the collecting box 42 moves to the bottom of the cotton block, so that the cleaned powder and debris can be collected, reducing the adhesion of these foreign matter to the workbench 11 and the battery electrode. When the cutting knife 15 moves downward, the trapezoidal plate 43 contacts the top of the bracket 41, and pushes the two together under the extrusion effect. The two collecting boxes 42 are far away from each other, and the two collecting boxes 42 are separated, so that the cutting knife 15 can cut downward normally. The positioning frame 18 can be positioned and guided by the first guide rod 51 to improve its stability. The cutting knife 15 can be positioned and guided by setting the second guide rod 52 to improve the cutting accuracy of the cutting knife 15. The pulley 6 is arranged on the top of the bracket 41 to contact the trapezoidal block, so as to reduce the friction on the bracket 41, thereby reducing the friction force and reducing the wear of the bracket 41. The pressing wheel 7 is set to reduce the friction force between the bottom end of the fixing rod 22 and the battery electrode, thereby reducing the wear of the fixing rod 22.
