Description

Technical Field

[0001] This utility model relates to the field of copper foil production technology, and in particular to a foil stripping mechanism for a foil production machine. Background Technology

[0002] In the copper foil production industry, the foil-forming machine is a key piece of equipment used to manufacture copper foil. The working principle of the foil-forming machine is to peel and collect the copper foil from the surface of the cathode roller by its rotation. In existing technology, after peeling the copper foil, the cathode roller is directly exposed to the air. Especially when producing ultra-thick copper foil, to ensure the quality and uniformity of the copper foil, the rotation speed of the cathode roller needs to be reduced. This leads to an increase in the time the cathode roller is exposed to air, thus accelerating the oxidation process. The oxidation of the cathode roller not only affects the quality of the copper foil and production efficiency but also increases maintenance costs and equipment downtime. Oxidized cathode rollers require frequent cleaning and replacement, which limits the mass production capacity of the foil-forming machine. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the existing foil stripping mechanism, which slows down the oxidation rate of the cathode roller, improves the service life and stability of the foil production machine, increases the mass production efficiency of ultra-thick copper foil, improves the surface quality of copper foil, reduces production costs, and enhances the adaptability and ease of operation of the equipment.

[0004] To solve the above-mentioned technical problems, this utility model provides a foil stripping mechanism, comprising:

[0005] An anode tank is provided with an anode plate and an electrolyte. Copper on the anode plate dissolves into the electrolyte to form copper ions. The copper ions are reduced and deposited in the electrolyte by the action of an electric current.

[0006] The cathode roller is set inside the cathode tank and is used as the negative electrode during the electrolysis of copper sulfate to deposit copper ions in the anode tank to form copper foil.

[0007] A stripping device is mounted on one side of the cathode roller via a displacement adjusting support and is used to strip copper foil from the cathode roller. The stripping device includes a stripping roller and a rolling support. The stripping roller is mounted on the displacement adjusting support via the rolling support, and the copper foil between the stripping point on the cathode roller and the stripping roller can cover the upper side of the cathode roller.

[0008] A support roller, mounted obliquely above the cathode roller via a first fixed bracket, is used to support the stripped copper foil.

[0009] The guide roller is mounted on one side of the support roller via a second fixed bracket, and is used to cooperate with the support roller to provide auxiliary support for the copper foil;

[0010] A winding device is provided on one side of the roller for winding the copper foil.

[0011] In one embodiment of this utility model, an edge-cutting device is further provided between the roller and the winding device for cutting the edge of the copper foil.

[0012] In one embodiment of this utility model, the edge trimming device includes a cutter holder, a first servo motor, a cutting blade, and a cutting roller. The cutter holder is mounted on a second fixed support, the cutting blade is mounted on the cutter holder via a rotating shaft, the drive shaft of the first servo motor is connected to the rotating shaft, the cutting roller is mounted on the second fixed support and is adjacent to the cutting blade, and the two ends of the cutting roller are provided with a plurality of cutting grooves.

[0013] In one embodiment of this utility model, the cutter holder is provided with a cutter protective cover.

[0014] In one embodiment of the present invention, the winding device includes a support frame, a winding roller, and a second servo motor. The winding roller is mounted on the support frame via a support base, and one end of the winding roller is connected to the output shaft of the second servo motor.

[0015] In one embodiment of this utility model, a cleaning mechanism is further provided on one side of the cathode roller for cleaning the copper foil.

[0017] In one embodiment of this utility model, a dewatering roller is provided on one side of the cathode roller near the second spray pipe to dewater the water adhering to the copper foil.

[0018] In one embodiment of this utility model, the displacement adjusting support includes a bracket, a sliding support, a linear slide rail, and a guide rod. The linear slide rail is disposed on both sides of the bracket, the sliding support is slidably connected to the linear slide rail, and the guide rod is disposed on the bracket and is arranged parallel to the linear slide rail.

[0019] In one embodiment of this utility model, the distance between the support roller and the cathode roller is greater than the distance between the guide roller and the cathode roller.

[0020] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:

[0021] The foil stripping mechanism of this invention features a stripping roller positioned away from the copper foil stripping point.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0031] Reference Figure 1 As shown, this utility model provides a foil stripping mechanism for a foil-making machine, comprising:

[0032] Anode tank 1 and anode tank 2 are provided with an anode plate and an electrolyte. Copper on the anode plate dissolves into the electrolyte to form copper ions. The copper ions are reduced and deposited in the electrolyte by the action of an electric current.

[0033] Cathode roller 2 is disposed in cathode tank 1 and is used as negative electrode during the electrolysis of copper sulfate to deposit copper ions in anode tank to form copper foil.

[0034] The stripping device 3 is mounted on one side of the cathode roller 2 via a displacement adjusting support 4, and is used to strip the copper foil on the cathode roller 3. The stripping device 3 includes a stripping roller 31 and a rolling support 32. The stripping roller 31 is mounted on the displacement adjusting support 4 via the rolling support 4, and the copper foil between the copper foil stripping point 100 on the cathode roller 2 and the stripping roller 31 can cover the upper side of the cathode roller 2.

[0035] The support roller 5 is positioned obliquely above the cathode roller 2 via the first fixed bracket 13, and is used to support the stripped copper foil;

[0036] The guide roller 6 is mounted on one side of the support roller 5 via the second fixed bracket 7, and is used to cooperate with the support roller 5 to provide auxiliary support for the copper foil;

[0037] A winding device 8 is disposed on one side of the guide roller 6 for winding the copper foil.

[0038] Based on the above structure, the stripping roller 31 is positioned away from the copper foil stripping point 100, so that when the copper foil is stripped, it can be stretched from the copper foil stripping point 100 to the stripping roller 31, and then the copper foil wraps around the cathode roller 2, preventing the cathode roller 2 from being directly exposed to the air, prolonging the oxidation time, significantly slowing down the oxidation rate of the cathode roller 2, and improving the service life and stability of the foil production machine.

[0039] Furthermore, an edge-cutting device 9 is provided between the roller 6 and the winding device 8 for cutting the edges of the copper foil. The addition of the edge-cutting device 9 improves the dimensional accuracy and yield of the copper foil, further enhancing product quality.

[0040] like Figure 2 As shown, the edge-cutting device 9 includes a cutter holder 91, a first servo motor 92, a cutting blade 93, and a cutting roller 94. The cutter holder 91 is mounted on a second fixed support 7. The cutting blade 93 is mounted on the cutter holder 91 via a rotating shaft 95. The drive shaft of the first servo motor 92 is connected to the rotating shaft 95. The cutting roller 94 is mounted on the second fixed support 7 and is adjacent to the cutting blade 93. The two ends of the cutting roller 94 are provided with a plurality of cutting grooves 941. The cutting blade 93 rotates under the drive of the first servo motor 92, enabling it to cooperate with the cutting grooves 941 to cut the edge of the copper foil. This makes the cutting of the copper foil edge more precise and stable, reducing errors and material waste during the cutting process.

[0041] Furthermore, the cutter holder 91 is equipped with a cutter protective cover. This protective cover enhances operator safety, preventing injury from the cutter blade 93 during high-speed cutting and improving overall production safety.

[0042] like Figure 4 As shown, the winding device 8 includes a support frame 81, a winding roller 82, and a second servo motor 83. The winding roller 82 is mounted on the support frame 81 via a support base, and one end of the winding roller 82 is connected to the output shaft of the second servo motor 83. This structural design makes the copper foil winding more uniform and compact, improving winding efficiency and packaging quality.

[0043] like Figure 3 As shown, a cleaning mechanism is also provided on one side of the cathode roller 2 for cleaning the copper foil. The cleaning mechanism includes a first spray pipe 10 and a second spray pipe 11. The first spray pipe 11 sprays an acidic solution onto the surface of the copper foil to remove oxides and copper oxides, while the second spray pipe 11 sprays clean water onto the surface of the copper foil to remove residual acid and reaction products.

[0044] Furthermore, a dewatering roller 12 is provided on one side of the cathode roller 2 near the second spray pipe 11 to squeeze off the water adhering to the copper foil. The dewatering roller 12 effectively removes moisture from the surface of the copper foil, reducing the impact of moisture on the copper foil in subsequent processing, and improving the drying efficiency and product quality of the copper foil.

[0045] like Figure 4 As shown, the displacement adjusting support 4 includes a bracket 41, a sliding support 42, a linear slide rail 43, and a guide rod 44. The linear slide rail 43 is disposed on both sides of the bracket 41, the sliding support 42 is slidably connected to the linear slide rail 43, and the guide rod 44 is disposed on the bracket 41 and parallel to the linear slide rail 43. The displacement adjusting support 4 provides the necessary adjustment function for the foil stripping mechanism of the foil-making machine to adapt to different production conditions and improve the control accuracy of the stripping process. This design enhances the flexibility and adaptability of the equipment and helps to improve the overall quality of copper foil products. In actual use, by adjusting the position of the sliding support 42 on the linear slide rail 43, the distance between the stripping roller 31 and the cathode roller 2 can be changed to adapt to the stripping requirements of copper foil of different thicknesses; the guide rod 44 ensures that the sliding support 42 maintains linear motion during movement, avoids deviation, and ensures that the position of the stripping device 3 is accurately controllable; the adjustment of the displacement adjusting support 4 can be achieved by manual or automatic control, wherein automatic control may involve a drive device to achieve precise position control.

[0046] Preferably, the distance between the support roller 5 and the cathode roller 2 is greater than the distance between the guide roller 6 and the cathode roller 2. This structural design optimizes the tension distribution of the copper foil during the peeling process, reduces the stretching and deformation of the copper foil, and improves the flatness and quality of the copper foil.

[0047] The working principle of the copper foil stripping mechanism of the foil forming machine is as follows: An anode plate and electrolyte are provided in the anode tank 1. Copper on the anode plate dissolves to form copper ions. The cathode roller 2 acts as the negative electrode during the electrolysis of copper sulfate, depositing copper ions in the anode tank to form copper foil. The stripping device 3 is responsible for stripping the copper foil from the surface of the cathode roller 2. The stripped copper foil is supported by the support roller 5 and further supported by the guide roller 6. Finally, it is wound up by the winding device 8. The edge-cutting device 9 is located between the guide roller 6 and the winding device 8, used to cut the edges of the copper foil to ensure dimensional accuracy. The first spray pipe 10 and the second spray pipe 11 are used to spray acidic solution to remove oxides from the copper foil surface and to clean it with water, respectively. The water-squeezing roller 12 is used to squeeze out the water from the copper foil. Throughout the stripping process, the copper foil is peeled off from the upper right side of the cathode roller 2 and moves to the left. The copper foil moves along this direction, is peeled off from the cathode roller 2, and is lifted by the support roller 5 to avoid contact with the cathode roller 2 and reduce oxidation. This process not only improves the production efficiency of ultra-thick copper foil but also reduces production costs, while enhancing the adaptability of the equipment and the ease of operation.

[0048] like Figure 6 The diagram illustrates the copper foil peeling process. The copper foil is peeled off from the peeling point 100 on the cathode roller 2, passing sequentially through the peeling roller 31, support roller 5, guide roller 6, and cutter roller 94, finally being wound onto the winding roller 82. The support roller 5 elevates the peeled copper foil to ensure it does not contact the cathode roller 2 during peeling, thus reducing oxidation of the cathode roller 2. After prolonged use, the peeling roller 2 can be replaced with a polishing brush to polish its surface, maintaining a smooth surface and reducing resistance during copper foil peeling.

[0049] Based on the foil stripping mechanism of the foil production machine in the above embodiment, the positions of the stripping roller 31 and the cathode roller 2 are set so that when the copper foil is stripped, the copper foil can be stretched from the copper foil stripping point 100 to the stripping roller, and the copper foil wraps around the cathode roller 2, avoiding the cathode roller 2 from being directly exposed to the air, prolonging the oxidation time, significantly slowing down the oxidation rate of the cathode roller 2, and improving the service life and stability of the foil production machine. This improvement not only improves the mass production efficiency of ultra-thick copper foil, but also improves the surface quality of the copper foil and reduces production costs.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
