Description

Technical Field

[0001] This utility model relates to the field of copper foil winding technology, specifically a lithium battery copper foil integrated winding device with adjustment function. Background Technology

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board, serving as a conductor in the PCB. It easily adheres to the insulating layer, receives printed protective layers, and forms circuit patterns after etching. The production process of lithium-ion battery copper foil mainly involves three steps: copper dissolution, electrolysis, and surface treatment. The treated copper foil is then wound up for convenient storage and transportation.

[0003] In the prior art, Chinese Utility Model Application No. CN202122504715.9 discloses a continuous winding device for lithium battery copper foil, which solves the problem that existing lithium battery copper foil is difficult to keep flat during winding and lacks practicality. It includes a support platform, with a first support plate at each of the two upper corners of the support platform. A compression spring is provided in the middle of the bottom end of the first support plate. Sliding grooves are formed on the inner walls of the first support plates on both sides of the compression spring. A slider is provided in the sliding groove, and a sliding block is provided between the sliders. A drive roller is provided in the middle of the sliding block. By setting up the first support plate, compression spring, sliding block, slider, sliding groove, drive roller, stepper motor and winding roller, the drive motor drives the drive roller to rotate, so that the winding roller can wind the lithium battery copper foil. At the same time, the drive roller assists the winding roller to keep the lithium battery copper foil flat on the winding roller, which is very practical.

[0004] The above technical solution uses a drive roller to drive a take-up roller to achieve the function of winding copper foil. However, in this technical solution, the copper foil needs to pass through the clamping roller during the process of installing the copper foil on the take-up roller. The distance between the upper and lower clamping rollers is fixed. When winding copper foil of different thicknesses, different winding equipment is required, which increases the cost of winding copper foil. At the same time, the stability of the installation of the take-up roller needs to be further improved. Therefore, we need to propose a lithium battery copper foil integrated winding device with adjustable function. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model mainly utilizes the cooperation between the protective frame, the adjustment mechanism, the first mounting groove, the third mounting groove, and the quick-release winding mechanism. Rotating the anti-slip wheel causes the adjusting screw to rotate within the protective frame, thereby moving the mounting frame along the first sliding groove. This facilitates quick adjustment of the gap between the upper and lower clamping rollers, allowing for rapid passage of copper foil. This facilitates fixing the copper foil onto the winding mechanism for winding. Furthermore, the clamping of the copper foil by the upper and lower clamping rollers improves the stability of copper foil conveying, making it suitable for conveying copper foil of different thicknesses and increasing the winding efficiency of copper foil.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This utility model provides a technical solution: a lithium battery copper foil integrated winding device with adjustable function, including a protective frame 2. The protective frame 2 has a first mounting groove 11, a second mounting groove 13 and a third mounting groove 15 on both sides inside. An adjusting mechanism 4 is slidably arranged in the first mounting groove 11. A lower clamping roller 6 is rotatably connected to the inside of the protective frame 2 below the adjusting mechanism 4. A driving mechanism 7 is arranged in the second mounting groove 13. A quick-release winding mechanism 8 is slidably arranged in the third mounting groove 15. Two sets of limit stops 9 are rotatably connected to one side of the protective frame 2.

[0022] The adjustment mechanism 4 includes a mounting frame 43 that is slidably connected in the first mounting groove 11. An adjustment screw 41 that is threadedly connected to the top of the guard frame 2 is rotatably provided on the upper surface of the mounting frame 43. An anti-slip wheel 42 is fixedly connected to the upper end of the adjustment screw 41. An upper clamping roller 5 is rotatably connected inside the mounting frame 43.

[0023] Both sides of the mounting frame 43 are fixedly connected with first sliders 44. Both sides of the inner cavity of the two sets of first mounting grooves 11 are provided with first sliding grooves 12 for sliding connection. The mounting frame 43 is U-shaped. The first sliders 44 slide in the first sliding grooves 12 to improve the stability of the mounting frame 43 when it drives the upper clamping roller 5 to move.

[0024] The quick-release winding mechanism 8 includes two sets of side blocks 81 slidably disposed in the third mounting groove 15. A winding roller 83 is rotatably connected between the two sets of side blocks 81. A third slider 82 is fixedly connected to both sides of the side blocks 81. A third slide groove 16 is provided on both sides of the interior of the third mounting groove 15 for the third slider 82 to slide. By using the third slider 82 to slide in the third slide groove 16, the stability of the winding roller 83 installation is improved.

[0025] The limiting stop bar 9 is L-shaped. One side of the side block 81 abuts against one side of the limiting stop bar 9. The two sets of side blocks 81 are fixedly connected to the side opposite to the take-up roller 83 with handles 84. The limiting stop bar 9 is used to limit the side block 81, preventing the side block 81 from disengaging from the third mounting groove 15, which improves the stability of the take-up roller 83. In addition, the limiting stop bar 9 is easy to rotate, which facilitates the disassembly of the quick-release take-up mechanism 8 and improves the efficiency of replacing the take-up roller 83.

[0026] The drive mechanism 7 includes two sets of mounting blocks 71 that are slidably disposed in the second mounting groove 13. A drive roller 72 located directly below the take-up roller 83 is rotatably connected between the two sets of mounting blocks 71. One end of the drive roller 72 passes through the mounting plate and is driven by a motor 73. The motor 73 drives the drive roller 72 to take up the take-up roller 83, thereby facilitating the rapid take-up of the copper foil.

[0027] A telescopic sleeve 74 is fixedly connected to the lower surface of the mounting block 71. The lower end of the telescopic sleeve 74 is fixedly connected to the bottom of the second mounting groove 13. A spring 75 is sleeved on the outer side of the telescopic sleeve 74. A second sliding groove 14 is opened on both sides inside the second mounting groove 13. A second slider is fixedly connected to both sides of the mounting block 71 and slidably disposed in the second sliding groove 14. The elastic potential energy of the spring 75 is used to make the drive roller 72 abut against the winding roller 83, thereby improving the flatness of the copper foil winding.

[0028] The lower surface of the guard frame 2 is welded with a base plate 1, and the upper surface of the guard frame 2 is provided with a top groove 10. A rotatable top cover 3 is rotatably connected in the top groove 10. The guard frame 2 prevents dust from falling on the copper foil surface during the winding process. The top cover 3 is easy to open and close, which facilitates the cutting of the wound copper foil, so as to wind the next winding roller 83.

[0029] In use, rotating the anti-slip wheel 42 causes the adjusting screw 41 to rotate on the guard frame 2, thereby adjusting the position of the mounting frame 43. This moves the upper clamping roller 5 away from the lower clamping roller 6, allowing the copper foil to be wound to pass between the upper and lower clamping rollers 5 and 6. Reversing the rotation of the anti-slip wheel 42 presses the upper clamping roller 5 firmly against the copper foil surface, facilitating the limiting of copper foil of different thicknesses, increasing its applicability, and improving the winding stability of the copper foil. One end of the copper foil is fixed to the winding roller. On 83, the drive mechanism 7 drives the quick-release winding mechanism 8 to wind up the copper foil. The elastic potential energy of the spring 75 causes the drive roller 72 to contact the winding roller 83, which facilitates the winding of the copper foil and ensures that the surface of the wound copper foil is flat. After winding, the top cover 3 is opened to cut the copper foil. The limit stop bar 9 is rotated 180 degrees, and then the winding roller 83 on the side block 81 is taken out by the handle 84, which facilitates the installation of the next winding roller 83 and improves the winding efficiency of the copper foil.
