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 technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an electrolytic copper foil tensioning device, including a base 1 and a connecting rod 11, a first U-shaped frame 3 is fixedly connected to the middle of the top of the base 1, a servo motor 4 is fixedly connected to the inner front side of the first U-shaped frame 3, a worm 5 is fixedly connected to the output end of the servo motor 4, a fixed plate 6 is fixedly connected to the left end of the inner top of the first U-shaped frame 3, a movable shaft 7 is rotatably connected to the right side of the fixed plate 6, a worm wheel 8 is fixedly connected to the middle of the outer side of the movable shaft 7, the worm wheel 8 is meshed with the worm 5, a fixed column 9 is fixedly connected to the right side of the worm wheel 8, a first rotating shaft 10 is rotatably connected to the outer side of the fixed column 9, and a slide groove is provided on the front and rear sides of the inner part of the first U-shaped frame 3. 21, the two chutes 21 are internally slidably connected with the same U-shaped plate 13, the U-shaped plate 13 is internally rotatably connected with a roller 14, the top of the U-shaped plate 13 is rotatably connected with a second rotating shaft 12, the second rotating shaft 12 is connected to the first rotating shaft 10 through a connecting rod 11, a disassembly mechanism 2 is arranged on the top right side of the base 1, the rear end of the worm 5 is rotatably connected to the inner rear side of the first U-shaped frame 3, the top left side of the base 1 is fixedly connected with a second U-shaped frame 15, the inner top of the second U-shaped frame 15 is fixedly connected with a cylinder 16, the output end of the cylinder 16 and the inside of the second U-shaped frame 15 are both fixedly connected with a fixed frame 17, and the inside of the fixed frame 17 is rotatably connected with a movable roller 18;

[0032] Specifically, the servo motor 4 can drive the worm 5 to rotate, and the worm wheel 8 tightly meshed with the worm 5 will rotate with the rotation of the worm 5. At this time, the first rotating shaft 10 connected thereto also starts to rotate, and the second rotating shaft 12 will also rotate through the connecting rod 11, thereby driving the U-shaped plate 13 to move upward inside the chute 21. While the U-shaped plate 13 moves, the roller 14 connected thereto also moves upward at any time, which can adjust the tension of the copper foil to a certain extent, so that the electrolytic copper foil is always in a tensioned state during the transportation process, thereby ensuring the flatness and stability of the electrolytic copper foil. This design not only improves the subsequent processing quality of the electrolytic copper foil, but also meets the user's demand for high-precision and high-efficiency production.

[0033] Reference Figure 3 and Figure 4The disassembly mechanism 2 includes a support plate 201, which is fixedly connected to the front right side of the top of the base 1. A servo motor 202 is fixedly connected to the front side of the support plate 201. The output end of the servo motor 202 passes through the support plate 201 and is fixedly connected to a rotating rod 203. A movable rod 204 is arranged on the outer side of the rotating rod 203. Holes 205 are provided on the upper and lower sides of the rotating rod 203. A first spring 206 is fixedly connected to one side of the inner part of the hole 205. One end of the first spring 206 is fixedly connected to a limiting rod 207. The ends of the two limiting rods 207 that are far away from each other pass through the upper and lower sides of the movable rod 204 respectively. The sizes of the two limiting rods 207 match the corresponding internal sizes of the holes 205.

[0034] Specifically, first press the limit rod 207. At this time, the first spring 206 will be squeezed by the force that drives the limit rod 207 to enter the hole 205. When the limit rod 207 successfully enters the hole 205, the original limit fixation on the movable rod 204 is released. At this time, the movable rod 204 can move freely and is no longer subject to any constraints. This provides convenient conditions for the following operations. Next, we can easily remove the rolled electrolytic copper foil from the device. Since the limit rod 207 has released the limit fixation on the movable rod 204, we can easily remove the electrolytic copper foil from the movable rod 204. This process is simple and fast, which greatly improves work efficiency.

[0035] Reference Figure 4 The disassembly mechanism 2 further includes a fixed plate 208, and the two fixed plates 208 are respectively fixedly connected to the front and rear sides of the outer wall of the movable rod 204, and the adjacent sides of the two fixed plates 208 are each provided with a groove 209, and the inner bottom of the groove 209 is fixedly connected to a second spring 210, and the tops of the two second springs 210 are fixedly connected to the same arc-shaped clamping plate 211;

[0036] Specifically, the arc-shaped clamping plate 211 is pulled upward, and then one end of the electrolytic copper foil is placed between the arc-shaped clamping plate 211 and the movable rod 204, and then the arc-shaped clamping plate 211 is released. At this time, the second spring 210 will rebound through its own elastic potential energy to limit and fix one end of the electrolytic copper foil, thereby preventing the electrolytic copper foil from shaking during the winding process and affecting its subsequent processing quality.

[0037] Reference Figure 1 A controller 19 is fixedly connected to the front side of the first U-shaped frame 3, and the controller 19 is electrically connected to the servo motor 202, the servo motor 4 and the cylinder 16 respectively. A protective cover 20 is arranged on the outside of the controller 19, and one side of the protective cover 20 is rotatably connected to the front side of the first U-shaped frame 3;

[0038] Specifically, the operation of the servo motor 202, the servo motor 4 and the cylinder 16 can be controlled by the controller 19, and the protective cover 20 can protect the controller 19 from being damaged by external factors.

[0039] Working principle: When using the device, first pass one end of the electrolytic copper foil to be processed through the two movable rollers 18, and then pass it through the top of the rotating roller 14. At this time, pull the arc clamping plate 211 upward, then put one end of the electrolytic copper foil between the arc clamping plate 211 and the movable rod 204, and then release the arc clamping plate 211. At this time, the second spring 210 will rebound through its own elastic potential energy to limit and fix one end of the electrolytic copper foil, and then drive the movable rod 204 to rotate through the servo motor 202, and the movable roller 18 will rotate accordingly to reel the electrolytic copper foil. At this time, the servo motor 4 can drive the worm 5 to rotate, and the worm wheel 8 will rotate accordingly due to the engagement with the worm 5, thereby driving the first When the rotating shaft 10 rotates, the second rotating shaft 12 will rotate accordingly, thereby driving the U-shaped plate 13 to move upward inside the slide groove 21, and the roller 14 will rotate accordingly, so that the electrolytic copper foil can be kept in a tensioned state during the transportation process, thereby improving the subsequent processing quality of the electrolytic copper foil and meeting the needs of users. After the winding work is completed, the limit rods 207 on both sides are pressed. At this time, the force exerted on the first spring 206 by the squeeze will drive the limit rods 207 to enter the holes 205, and the limit fixation of the movable rod 204 can be released. Then the wound electrolytic copper foil can be removed for collection. It is relatively simple to disassemble the wound electrolytic copper foil, thereby improving the practicality of the device.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
