[0002] The foil machine is the main equipment in the production of electrolytic copper foil. It consists of an anode and a cathode. The anode generally uses a DSA insoluble anode, and the cathode generally uses a TA1 grade cathode roller with a high particle grade. The cathode is connected to the negative electrode, and the anode is connected to the positive electrode. Under the action of direct current, the copper sulfate solution in the foil machine precipitates on the surface of the cathode roller, and the copper foil is obtained by continuous peeling and winding as the cathode roller rotates. However, during the production of electrolytic copper foil, due to the edge effect, copper will also precipitate and adhere to the two sides of the cathode roller, and it is difficult to peel off.

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

[0022] See also Figures 1 to 6 The utility model provides a technical solution: an auxiliary cathode structure for reducing edge copper plating, comprising two copper plates 1 and a copper rod 2, fixing rings 3 are respectively arranged at both ends of the copper rod 2, frames 4 are arranged at the front ends of the two copper plates 1, shells 5 are arranged at the front ends of the two frames 4, driving components are arranged in the inner cavities of the two shells 5, and splints 6 are arranged at the rear ends of the two driving components. Connecting components are respectively arranged on the left and right sides of the inner cavity of the frame 4, and positioning holes 7 are opened on the rear side of the splint 6. The inner cavity of the positioning hole 7 is detachably plugged with a positioning rod 8, and the rear end of the positioning rod 8 is fixedly connected to the front end of the copper plate 1. The fixing ring 3 is sleeved on the outer wall of the positioning rod 8 and is in close contact with the front end of the copper plate 1. The driving assembly drives the clamping plate 6 to slide along a straight line toward the copper plate 1 under the limiting action of the connecting assembly, so that the positioning hole 7 is sleeved on the outer wall of the positioning column and the clamping plate 6 cooperates with the copper plate 1 to clamp the fixing ring 3 to prevent the fixing ring 3 from detaching from the positioning column, thereby achieving the fixation of one end of the copper rod 2, solving the problem that the copper rod 2 in the prior art is only overlapped on the copper plate 1 and cannot be fixed, and the copper rod 2 often detaches from the copper plate 1 during use, resulting in edge effect and poor stability.

[0023] In this embodiment, the connecting component includes a connecting groove 16 and a connecting block 17. The connecting groove 16 is opened on one side of the inner wall of the frame 4. The connecting block 17 can be slidably embedded in the inner cavity of the connecting groove 16 and fixedly connected to one end of the splint 6. Under the interaction between the connecting groove 16 and the connecting block 17, the splint 6 can always slide along a straight line.

[0024] In this embodiment, the inner cavity of the connecting groove 16 is matched with the outer wall of the connecting block 17 and both are dovetail-shaped, so that one end of the connecting block 17 can always remain embedded in the inner cavity of the connecting groove 16, thereby improving the stability of the connecting assembly during use.

[0025] In this embodiment, the driving assembly includes a screw rod 9, a handle 10, a slider 11, a fixing seat 14, a connecting rod 15 and a limit assembly. One end of the screw rod 9 is rotatably connected to the left side of the inner cavity of the casing 5 through a bearing, and the other end of the screw rod 9 extends to the right end of the casing 5 and is fixedly connected to the handle 10. The two sliders 11 are respectively screwed to the left and right sides of the outer wall of the screw rod 9. The fixing seat 14 is arranged at the front end of the splint 6. One end of the two connecting rods 15 is respectively hinged to the left and right sides of the front end of the fixing seat 14. The other ends of the two connecting rods 15 are respectively hinged to the rear sides of the two sliders 11. The limit assembly is arranged at the front side of the inner cavity of the casing 5 and is fixedly connected to the two sliders 11. Rotating the handle 10 causes the handle 10 to drive the screw rod 9 to rotate, thereby causing the outer wall of the screw rod 9 to move left and right. The threads opposite to each other on both sides generate relative thread rotation force, so that the two sliders 11 slide toward the middle of the screw rod 9 at the same time under the limiting action of the limiting groove 12 and the limiting block 13, so that the two connecting rods 15 push the fixing seat 14 and the clamping plate 6 to slide along a straight line toward the copper plate 1 under the limiting action of the connecting groove 16 and the connecting block 17, so that the positioning hole 7 is sleeved on the outside of the positioning column, and the clamping plate 6 cooperates with the copper plate 1 to clamp and fix the fixing ring 3 to prevent the fixing ring 3 from detaching from the positioning column, thereby achieving the fixation of one end of the copper rod 2, solving the problem that the copper rod 2 in the prior art is only overlapped on the copper plate 1 and cannot be fixed, and the copper rod 2 often detaches from the copper plate 1 during use, resulting in edge effect and poor stability.

[0026] In this embodiment, the threads on the left and right sides of the outer wall of the screw rod 9 are arranged relative to each other, so that when the screw rod 9 rotates, the left and right sides of its outer wall generate relative thread rotation forces, so that the two sliders 11 slide relatively at the same time under the limiting action of the limiting groove 12 and the limiting block 13.

[0027] In this embodiment, the limit assembly includes a limit groove 12 and a limit block 13. The limit groove 12 is opened on the front side of the inner cavity of the casing 5. The two limit blocks 13 can be slidably embedded in the inner cavity of the limit groove 12 and fixedly connected with the two sliders 11. Under the interaction between the limit groove 12 and the limit block 13, the slider 11 can be prevented from rotating with the screw rod 9 when the screw rod 9 rotates, thereby improving the stability of the drive assembly during use. The inner cavity of the limit groove 12 and the outer wall of the limit block 13 are matched and both are in a "T" shape, so that one end of the limit block 13 can always remain embedded in the inner cavity of the limit groove 12, thereby improving the stability of the limit assembly during use.

[0028] In this embodiment, the outer circumference of the handle 10 is provided with anti-slip edges, which can increase the roughness of the outer circumference of the handle 10, thereby preventing the handle 10 from slipping out of the hand when rotating, thereby improving the stability of the device when in use.

[0029] The use method and advantages of the utility model: When in use, the working process is as follows:

[0030] The fixing ring 3 at one end of the copper rod 2 is sleeved on the outside of the positioning column, and the handle 10 is rotated to make the handle 10 drive the screw rod 9 to rotate, so that the threads on the left and right sides of the outer wall of the screw rod 9 generate relative thread rotation force, so that the two sliders 11 slide toward the middle of the screw rod 9 at the same time under the limiting action of the limiting groove 12 and the limiting block 13, so that the two connecting rods 15 push the fixing seat 14 and the clamping plate 6 to slide along a straight line toward the copper plate 1 under the limiting action of the connecting groove 16 and the connecting block 17, so that the positioning hole 7 is sleeved on the outside of the positioning column, and the clamping plate 6 cooperates with the copper plate 1 to clamp and fix the fixing ring 3 to prevent the fixing ring 3 from detaching from the positioning column, thereby achieving the fixation of one end of the copper rod 2, solving the problem that the copper rod 2 in the prior art is only overlapped on the copper plate 1 and cannot be fixed, and the copper rod 2 often detaches from the copper plate 1 during use, resulting in edge effect and poor stability.
