Description

Technical Field

[0001] This invention belongs to the technical field of copper foil rolling equipment, and particularly relates to a copper foil rolling mill with a precision grinding system for microstructured roller surfaces. Background Technology

[0002] The roll surfaces of copper foil rolling mills typically need to be machined with specific micro-textures, such as micro-pits, micro-grooves, or spiral lines. These microstructures facilitate the peeling of copper foil after rolling and improve the surface quality of the copper foil. However, during long-term use, the roll surface will gradually develop local high points, oxide scale, scratches, and wear of the original microstructure. In order to ensure the product quality of copper foil, the roll surface must be regularly re-grinded to restore its surface precision and microstructure morphology.

[0003] Most existing roller surface grinding devices use fixed contact points or contact surfaces, meaning the way the grinding belt adheres to the roller surface is fixed. For example, in the single-point contact method, the contact area between the grinding belt and the roller surface is small and the pressure is concentrated, which can quickly remove local high points or heavy wear layers on the roller surface, resulting in high grinding efficiency. However, this method has poor grinding uniformity, easily leaving uneven ripples on the roller surface, and it is difficult to accurately control the final precision of the microstructure. It cannot flexibly switch according to the actual grinding stage, such as coarse grinding followed by fine grinding, which means sacrificing grinding quality for efficiency or sacrificing efficiency to ensure precision. Summary of the Invention

[0004] The purpose of this invention is to provide a precision grinding mill for copper foil with microstructure on the roller surface, which solves the technical problem that the existing roller surface grinding device has a fixed bonding method with the roller surface and cannot be adapted to various grinding stages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precision grinding copper foil rolling mill with microstructured roll surfaces includes a copper foil rolling mill body and a roll surface repair mechanism disposed on the copper foil rolling mill body. The roll surface repair mechanism includes a repair component and an adjustment component. In the repair component, a grinding belt is wound between a first drive roll, a second drive roll, a third drive roll, and a fourth drive roll. The grinding belt is used to contact and grind the roll surface of the copper foil rolling mill body. The adjustment component is connected to the third drive roll and is used to drive the third drive roll to move relative to the first drive roll and the fourth drive roll to change the contact wrap angle between the grinding belt and the roll surface. When the contact wrap angle is a first angle, the grinding belt adheres to the roll surface in a single-point contact manner. When the contact wrap angle is a second angle, the grinding belt adheres to the roll surface in a multi-point contact manner.

[0007] According to some embodiments, the roller surface repair mechanism further includes a circulation drive assembly, which includes: a storage box with a water pump fixedly installed inside; a third guide pipe, one end of which is fixedly connected to the outlet end of the water pump, and the other end of which is fixedly installed with a drive box; a sixth guide pipe, which is rotatably mounted on the drive box, with an impeller fixedly mounted on it and fixedly connected to the third drive roller; and a fifth guide pipe, one end of which is fixedly connected to the drive box, and the other end of which is rotatably connected to the sixth guide pipe.

[0008] According to some embodiments, the circulation drive assembly further includes: a second guide tube, which is divided into three sections, with the middle section rotatably connected to the second drive roller, and the upper and lower sections being flexible tubes that are fixedly connected to the storage box and the sixth guide tube, respectively.

[0009] According to some embodiments, the circulation drive assembly further includes: a first guide tube, which is divided into three sections, the middle section being a rigid tube rotatably connected to the first drive roller, and the upper and lower sections being flexible tubes respectively fixedly connected to the storage box and the sixth guide tube.

[0010] According to some embodiments, the circulation drive assembly further includes: a fourth guide tube, which is divided into three sections, the middle section being a rigid tube rotatably connected to the fourth drive roller, and the upper and lower sections being flexible tubes respectively fixedly connected to the storage box and the sixth guide tube.

[0011] According to some embodiments, the control component includes: a mounting bracket, which is fixedly mounted on the storage box and fixedly connected to the middle section of the second guide tube, and a sliding groove is provided through the mounting bracket.

[0012] According to some embodiments, the control component further includes: an electric push rod, fixedly mounted on the mounting frame, with a sliding frame slidably connected to the mounting frame fixedly mounted on its telescopic end; the sliding frame is fixedly connected to the sixth guide pipe.

[0013] According to some embodiments, the control component further includes: two rotating plates, which are fixedly connected to the middle section of the first guide tube and the middle section of the fourth guide tube, respectively, and each plate is fixedly mounted with a gear; and a gear frame, which is fixedly connected to the sliding frame and meshes with the gear.

[0014] According to some embodiments, the roller surface repair mechanism further includes a pressure regulating component, which includes: a mounting cover, fixedly mounted on the copper foil rolling mill body and slidably connected to the storage box; a screw, rotatably mounted on the mounting cover, on which a threaded plate is threadedly connected; and a spring, one end of which is connected to the threaded plate and the other end of which is connected to the storage box.

[0015] According to some embodiments, the pressure regulating assembly further includes: a guide post, which is fixedly mounted on the mounting cover and slidably connected to the threaded plate.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. This invention drives the third drive roller to move by adjusting the component, changing the contact wrap angle between the grinding belt and the roller. It can switch between single-point contact and multi-point contact. When there is single-point contact, the pressure is concentrated, which can quickly remove local high points, oxide scale and heavily worn layers on the roller surface. When there is multi-point contact, the pressure is evenly distributed, which can precisely repair the microstructure of the roller surface, taking into account both rough grinding efficiency and fine grinding accuracy.

[0018] 2. The circulating drive assembly of the present invention utilizes a water pump to drive the coolant to circulate. The coolant drives the impeller to rotate, thereby driving each drive roller to move synchronously with the grinding belt, so that the grinding belt continuously circulates and changes the grinding position, avoiding excessive local wear. At the same time, the coolant indirectly exchanges heat through the drive rollers, promptly removing the heat generated during grinding, preventing the roller surface from overheating, burning, softening, or microstructural deformation.

[0019] 3. The pressure regulating component of the present invention adjusts the position of the threaded plate by adjusting the screw, changes the clamping force of the spring on the storage box, and then adjusts the contact pressure between the grinding belt and the roller surface. The pressure can be flexibly set according to the grinding requirements. With the flexible pressure of the spring, it adapts to the runout and ellipticity of the roller surface, avoids rigid impact damage to the roller surface, and is suitable for grinding conditions of different depths and precisions.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0034] This invention is described in detail with reference to the accompanying drawings. In the detailed description of the embodiments of this invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not to scale. Furthermore, the accompanying drawings are merely examples and should not be construed as limiting the scope of protection of this invention. In actual fabrication, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0035] Furthermore, it should be noted in the description of this invention that the terms "first," "second," or "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" in this invention should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; similarly, they can refer to mechanical connections, electrical connections, or direct connections, or indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] Example 1: As Figures 1 to 9 As shown, a precision grinding copper foil rolling mill with microstructured roller surfaces includes a copper foil rolling mill body 100 and a roller surface repair mechanism 200. The roller surface repair mechanism 200 is disposed on the copper foil rolling mill body 100 and includes a repair component 230 and an adjustment component 240. In the repair component 230, a grinding belt 231 is wound between a first drive roller 232, a second drive roller 233, a third drive roller 234, and a fourth drive roller 235. 31 is used to contact and grind the roll surface of the copper foil rolling mill body 100; the control component 240 is connected to the third drive roller 234 and is used to drive the third drive roller 234 to move relative to the first drive roller 232 and the fourth drive roller 235 to change the contact wrap angle between the grinding belt 231 and the roll surface; when the contact wrap angle is the first angle, the grinding belt 231 is attached to the roll surface in a single-point contact manner; when the contact wrap angle is the second angle, the grinding belt 231 is attached to the roll surface in a multi-point contact manner.

[0038] It should be noted that the surface of the rolls in a copper foil rolling mill typically requires specific microstructures, such as micro-pits, micro-grooves, or spirals, to ensure the peelability and surface quality of the copper foil. After long-term rolling, local high points, oxide scale, scratches, or microstructural wear may appear on the roll surface. Most existing grinding devices use a fixed contact angle, resulting in a single contact pattern between the grinding belt 231 and the roll surface. Although this method can concentrate pressure to quickly remove local high points, it is prone to producing uneven ripples, making it difficult to guarantee the accuracy of the final microstructure. By controlling the third drive roll 234 relative to the first drive roll 232 and the fourth drive roll 235 through the control component 240, the contact pattern between the grinding belt 231 and the roll surface is changed. The contact wrap angle between the roller surfaces; when the contact wrap angle is the first angle, the grinding belt 231 is attached to the roller surface in a single-point contact manner, the pressure is concentrated, and the local high points or heavily worn areas are efficiently removed; when the contact wrap angle is the second angle, the grinding belt 231 is attached to the roller surface in a multi-point contact manner, the pressure is evenly distributed, and the roller surface microstructure is precisely repaired and the roughness is reduced. The first angle is a small wrap angle, that is, the grinding belt 231 at the second drive roller 233 is in single-point contact with the roller surface, and the second angle is a large wrap angle, that is, the first drive roller 232, the second drive roller 233 and the fourth drive roller 235 form an angle of 100°-130° and contact the roller surface.

[0039] like Figure 1 , Figure 3 , Figures 7 to 9As shown, the roller surface repair mechanism 200 also includes a circulation drive assembly 220, which includes a storage box 221, a first guide pipe 222, a second guide pipe 223, a third guide pipe 224, a drive box 225, a fourth guide pipe 226, a water pump 227, a fifth guide pipe 228, a sixth guide pipe 229, and an impeller 2291. The water pump 227 is fixedly installed inside the storage box 221. One end of the third guide pipe 224 is fixedly connected to the outlet end of the water pump 227, and the other end of the third guide pipe 224 is fixedly installed with the drive box 225. The sixth guide pipe 229 is rotatably mounted on the drive box 225, and an impeller 2291 is fixedly installed on the sixth guide pipe 229. The sixth guide pipe 229 is fixedly connected to the third drive roller 234. One end of the fifth guide pipe 228 is fixedly connected to the drive box 225, and the other end of the fifth guide pipe 228 is fixedly connected to the sixth drive roller 234. The flow guide pipe 229 is rotatably connected; the circulation drive assembly 220 also includes a first flow guide pipe 222 divided into three sections. The middle section of the first flow guide pipe 222 is a rigid pipe rotatably connected to the first drive roller 232, and the upper and lower sections of the first flow guide pipe 222 are flexible hoses, which are fixedly connected to the storage box 221 and the sixth flow guide pipe 229 respectively. The circulation drive assembly 220 also includes a fourth flow guide pipe 226 divided into three sections. The middle section of the fourth flow guide pipe 226 is a rigid pipe rotatably connected to the fourth drive roller 235, and the upper and lower sections of the fourth flow guide pipe 226 are flexible hoses, which are fixedly connected to the storage box 221 and the sixth flow guide pipe 229 respectively. The circulation drive assembly 220 also includes a second flow guide pipe 223 divided into three sections. The middle section of the second flow guide pipe 223 is rotatably connected to the second drive roller 233, and the upper and lower sections of the second flow guide pipe 223 are flexible hoses, which are fixedly connected to the storage box 221 and the sixth flow guide pipe 229 respectively.

[0040] It should be noted that the storage box 221 contains coolant. When the water pump 227 starts, it draws the coolant from the storage box 221 into the third guide pipe 224. The coolant in the third guide pipe 224 then flows through the drive box 225 into the fifth guide pipe 228. However, the coolant in the drive box 225 drives the impeller 2291 to rotate, which in turn drives the sixth guide pipe 229 to rotate. This will drive the third drive roller 234 to rotate. The third drive roller 234, through the grinding belt 231, will cause the first drive roller 232, the second drive roller 233, and the fourth drive roller 235 to rotate together. In this way, the grinding belt 231 will continuously transmit power. The continuous transmission of the grinding belt 231 allows for multiple contact points between the grinding belt 231 and the roller surface, avoiding damage caused by prolonged single-point contact grinding. Furthermore, the continuous circulation of the grinding belt 231 and the multi-faceted contact can prevent the accumulation of impurities during grinding. During the transmission process of the grinding belt 231, impurities can be carried away. Simultaneously, the linear speed of the grinding belt 231 is automatically matched with the coolant flow rate, preventing overload slippage or speed fluctuations and ensuring a smooth and uniform grinding process. Furthermore, the coolant entering the fifth guide pipe 228 will enter the sixth guide pipe 229, and then be distributed through the sixth guide pipe 229 to the fourth guide pipe 226, the second guide pipe 223, and the first guide pipe 222. Finally, the coolant flows through the fourth guide pipe 226, the second guide pipe 223, and the first guide pipe 222. A guide pipe 222 returns to the storage box 221, forming a liquid circulation. The coolant circulates in the closed pipe and undergoes indirect heat exchange with the grinding belt 231 and the roller surface contact area through the roller walls of the first drive roller 232, the second drive roller 233, the third drive roller 234 and the fourth drive roller 235. This promptly removes the local high temperature generated during contact rough grinding, preventing the roller surface from burning, softening or microstructural deformation due to overheating. It is also suitable for the first angle working state and can be adapted to the second angle working state.

[0041] like Figure 4 and Figure 5 As shown, the control component 240 includes a mounting bracket 241, a sliding bracket 242, a gear bracket 243, an electric push rod 244, a rotating plate 245, and a gear 246; the mounting bracket 241 is fixedly mounted on the storage box 221, and the mounting bracket 241 is fixedly connected to the middle section of the second guide pipe 223, and a sliding groove is provided through the mounting bracket 241.

[0042] The control assembly 240 also includes an electric push rod 244 fixedly mounted on the mounting bracket 241. A sliding frame 242 that is slidably connected to the mounting bracket 241 is fixedly mounted on the telescopic end of the electric push rod 244. The sliding frame 242 is fixedly connected to the sixth guide tube 229.

[0043] The control assembly 240 also includes two rotating plates 245 that are fixedly connected to the middle section of the first guide pipe 222 and the middle section of the fourth guide pipe 226, respectively. Gears 246 are fixedly installed on both rotating plates 245. The gear frame 243 is fixedly connected to the sliding frame 242, and the gear frame 243 meshes with the gears 246.

[0044] It should be noted that by activating the electric push rod 244, the sliding frame 242 can be moved. The movement of the sliding frame 242 can control the movement of the sixth guide pipe 229 and the third drive roller 234. When the third drive roller 234 approaches the second drive roller 233, the gear frame 243 will drive the two gears 246 to rotate. In this way, the two rotating plates 245 will drive the first drive roller 232 and the fourth drive roller 235 to unfold, so that the grinding belt 231 only contacts the roller surface at the second drive roller 233 for grinding. When the third drive roller 234 moves away from the second drive roller 233, the first drive roller 232 and the fourth drive roller 235 will continuously approach the roller surface, so that the grinding belt 231 at the first drive roller 232 and the fourth drive roller 235 presses on the roller surface, forming multi-faceted grinding and dispersing pressure. The pressure at the first drive roller 232 and the fourth drive roller 235 can be adjusted according to the degree of rotation.

[0045] The working principle of this embodiment:

[0046] The water pump 227 of the circulation drive assembly 220 is started, sending the coolant in the storage box 221 into the third guide pipe 224 and the drive box 225. The coolant drives the impeller 2291 to rotate, which in turn drives the sixth guide pipe 229 and the third drive roller 234 to rotate. The third drive roller 234 drives the first drive roller 232, the second drive roller 233, and the fourth drive roller 235 to operate synchronously through the grinding belt 231. The grinding belt 231 moves in a cycle to grind the roll surface. The coolant is diverted through the fifth guide pipe 228 and the sixth guide pipe 229 to the first guide pipe 222, the second guide pipe 223, and the fourth guide pipe 226, and then flows back to the storage box 221, forming a circulating cooling system to remove the heat from the grinding process. The electric push rod 244 of the control assembly 240 is started, pushing the sliding frame 242 to slide along the mounting frame 241, which in turn moves the sixth guide pipe 229 and the third drive roller 234. The sliding frame 242 drives the gear frame 243 to move and mesh. The gear 246 drives the rotating plate 245 to rotate, adjusting the positions of the first drive roller 232 and the fourth drive roller 235, and changing the contact wrap angle between the grinding belt 231 and the roller surface. When the contact wrap angle is the first angle, the grinding belt 231 contacts the roller surface at a single point, the pressure is concentrated, and the high points, oxide scale and wear layer of the roller surface are quickly removed. When the contact wrap angle is the second angle, the grinding belt 231 contacts the roller surface at multiple points, the pressure is uniform, and the microstructure of the roller surface is precisely repaired. In the pressure regulating component 210, the rotating screw 213 drives the threaded plate 215 to move along the guide column 212, adjusting the clamping force of the spring 214 on the storage box 221, changing the contact pressure between the grinding belt 231 and the roller surface, and adapting to different grinding conditions.

[0047] Example 2: As Figure 1 and Figure 2 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0048] The roller surface repair mechanism 200 also includes a pressure regulating component 210, which includes a mounting cover 211, a guide post 212, a screw 213, a spring 214, and a threaded plate 215. The mounting cover 211 is fixedly mounted on the copper foil rolling mill body 100 and is slidably connected to the storage box 221. The screw 213 is rotatably mounted on the mounting cover 211 and is threadedly connected to the threaded plate 215. One end of the spring 214 is connected to the threaded plate 215, and the other end of the spring 214 is connected to the storage box 221. The guide post 212 is fixedly mounted on the mounting cover 211 and is slidably connected to the threaded plate 215.

[0049] The working principle of this embodiment:

[0050] By setting spring 214, the first drive roller 232, the second drive roller 233, and the fourth drive roller 235 can apply pressure to the roller surface, which allows the grinding belt 231 to better fit the roller surface for grinding. Furthermore, by rotating screw 213, the threaded plate 215 can be moved, allowing it to compress spring 214. Since the position of the threaded plate 215 is fixed after adjustment, while the position of the storage box 221 is always floating, the compression of spring 214 will apply a greater force to the storage box 221, thus increasing the pressure on the grinding belt at the first drive roller 232, the second drive roller 233, and the fourth drive roller 235. 231 can fit more closely to the roller surface. This not only allows the flexible pressure of the spring 214 to adapt to the slight vibration or ellipticity of the roller surface, avoiding damage to the roller surface caused by rigid impact; especially in the single-point contact grinding mode, the pressure can be increased to concentrate the removal of local high points or heavily worn areas, improving the rough grinding efficiency; in the multi-point contact grinding mode, the pressure can be appropriately reduced to make the grinding belt 231 fit evenly to the roller surface, achieving precise repair of microstructure and reducing roughness. It can also provide the required clamping force to the grinding belt 231 according to the actual grinding needs. If shallow grinding is required, the pressure is small, and there is slight friction with the roller surface; if deep grinding is required, the pressure is large, and there is deep friction with the roller surface.
