Titanium roll edge secondary polishing and grinding tooling

Abstract

The application discloses a titanium roller edge secondary polishing and grinding tool and relates to the technical field of copper foil processing. The tool comprises a polishing roller for polishing the edge of a titanium roller, a driving motor for driving the polishing roller to work, a bearing sleeve for adjusting the angle of the polishing roller, and a rotating base for switching the position of the polishing roller to make it leave the working range of the titanium roller. The titanium roller edge secondary polishing and grinding tool can not only focus on the treatment of the end of a cathode roller, but also adjust the gap increase caused by the wear of the polishing roller when the polishing roller polishes and grinds the cathode roller, so that the gap between the polishing roller and the cathode roller is always the same, which facilitates the subsequent operator to reduce the adjustment amount when performing pressure fine adjustment. In addition, when the polishing roller is polishing, oxides will appear on the surface of the polishing roller. The device can detect the friction of the polishing roller, so as to timely treat the surface of the polishing roller and ensure the polishing effect of the polishing roller.

Description

Technical Field

[0001] This invention relates to the field of copper foil processing technology, and in particular to a secondary polishing fixture for the edge of a titanium roller. Background Technology

[0002] Titanium cathode rollers are the core equipment in the electrolytic manufacturing of copper foil. In the electrolytic cell, the cathode rollers are corroded by the copper sulfate solution and the electrolytic process, causing the oxide film on the surface of the cathode roller to gradually thicken, increasing roughness and surface area. This results in a decrease in cathode overpotential, leading to coarse copper ion electrodeposition crystals on the cathode roller surface. Increased hydrogen evolution at the cathode causes hydrogen corrosion on the surface, forming a solid solution, which accelerates the corrosion rate and further thickens the oxide film. Consequently, the brightness of the produced copper foil surface decreases significantly, and the crystalline structure becomes coarse. In severe cases, slight copper powder may be present on the copper foil surface. Therefore, after a period of operation, the cathode roller surface must be ground. Polishing equipment is used during the oxidation process of the titanium roller surface.

[0003] However, oxidation is particularly noticeable at the ends of the cathode roller, requiring further focused treatment. Existing online polishing equipment typically performs overall polishing, necessitating the design of a secondary polishing device specifically for end oxidation. Furthermore, during the polishing of the cathode roller, the polishing rollers on the equipment experience wear. This requires manual manipulation of the polishing rollers (equipped with a pressure sensor to determine the distance and contact force between the cathode and polishing rollers) to ensure proper contact between the polishing rollers and the cathode. The pressure between the rollers (which is a relatively fine-tuning step during manual operation) increases the gap between the polishing roller and the cathode roller when the polishing roller wears down. This leads to a corresponding increase in the distance that needs to be fine-tuned, thus increasing the operation time. Furthermore, when using the polishing roller to polish the oxide on the cathode roller, it is affected by the oxide. The oxide is highly dispersed and has strong adsorption properties, so it may adhere to the surface of the nylon roller, thereby changing its coefficient of friction. This results in a worse polishing effect under the same amount of contact force, thus affecting the operation. Summary of the Invention

[0004] The present invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The present invention provides a secondary polishing fixture for the edge of a titanium roller to solve the technical problem that existing polishing equipment suffers from poor polishing effect due to the influence of oxides during polishing.

[0005] The present invention adopts the following technical solution: a secondary polishing fixture for the edge of a titanium roller, which further includes a polishing roller for polishing the edge of the titanium roller, a drive motor for driving the polishing roller to work, a bearing sleeve for adjusting the angle of the polishing roller, an adjustment handle for adjusting the polishing position of the polishing roller, a rotating base for switching the position of the polishing roller to move it away from the working range of the titanium roller, a gap adjustment mechanism for adjusting the position of the worn polishing roller to make the fine adjustment distance the same, a surface treatment mechanism for treating the surface of the polished polishing roller, and a safety plate to prevent personnel injury.

[0006] Furthermore, the surface treatment mechanism includes a scraper, with a liquid replenishment box at the upper end of the scraper, a pressing block inside the liquid replenishment box, several liquid outlet holes at one end of the scraper, a mating plate inside the scraper, several through holes on the mating plate, a movable abutment block at the bottom of the scraper, a mating hydraulic rod between the movable abutment block and the inner wall of the scraper, a pushing hydraulic rod above the mating plate, and a second connecting pipe between the pushing hydraulic rod and the mating hydraulic rod.

[0007] Furthermore, the contact edge of the scraper is inclined.

[0008] Furthermore, in the initial state, the through holes and liquid outlet holes in the mating plate are misaligned.

[0009] Furthermore, the gap adjustment mechanism includes an electric telescopic rod and a slide rail. A processor and an electromagnetic flow direction switch are located in the middle of the electric telescopic rod. A slider is located below the drive motor and is slidably connected to the slide rail. An electric telescopic rod is positioned between the slider and the safety plate. A mating magnet is located below the other end of the scraper. An electromagnet is located below the mating magnet and is positioned on the safety plate. A rotating shaft is located at the lower center of the scraper. A hydraulic telescopic rod is positioned between the rotating shaft and the bottom of the scraper. A hydraulic box is located below the electromagnet, and a gravity sensor is located inside the hydraulic box. A first connecting pipe is positioned between the hydraulic telescopic rod and the hydraulic box. A control hydraulic rod is positioned between the mating magnet and the electromagnet, and the control hydraulic rod is connected to a second connecting pipe via a third connecting pipe.

[0010] Furthermore, the first connecting pipe is a one-way valve pipe.

[0011] Furthermore, the cross-section of the hydraulic telescopic rod is arc-shaped, and a return spring is provided in the hydraulic telescopic rod, the cooperating hydraulic rod, and the ejecting hydraulic rod.

[0012] Furthermore, the direction of current flow in the electromagnet is adapted to the rotation angle of the rotating base.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] Firstly, the grinding roller of this device can focus on grinding the end of the cathode roller. Based on the length of the end of the cathode roller, where oxidation is prone to occur during actual production, an appropriately sized grinding roller is selected for secondary processing. Secondly, the diameter of the grinding roller can be detected by the set gap adjustment mechanism, and then the position of the grinding roller is adjusted synchronously to ensure that the gap between the grinding roller and the cathode roller remains the same during operation. This facilitates fine-tuning of the pressure between the grinding roller and the cathode roller by the operator. During the grinding process, the diameter of the grinding roller changes due to frictional wear, so that when the subsequent grinding roller moves to the working position, the grinding roller... The gap between the grinding roller and the cathode roller is relatively large. However, this situation can be avoided by using a gap adjustment mechanism. During the use of the gap adjustment mechanism, a scraper that can deflect at an angle is used for detection. The smaller the diameter of the grinding roller, the larger the deflection angle required for the scraper to contact the grinding roller. Then, the electric telescopic rod is controlled to work according to the deflection angle to move it laterally. However, the height of the grinding roller does not change at this time (that is, only the gap between the grinding roller and the cathode roller is adjusted, but the height of the grinding roller does not change. When the scraper adjusts the height, it is still based on the previous height, and the deflection angle becomes larger and larger). This ensures the accuracy of the detection data and simplifies the operation of subsequent operators.

[0015] Secondly, during use, a scraper that contacts the surface of the grinding roller is used to scrape the grinding roller. The scraper is hollow and can be filled with a treatment agent. When the grinding roller is affected by the cathode roller and oxides appear on its surface, simple scraping is insufficient to remove the oxides. A treatment agent needs to be sprayed onto the surface before scraping. However, the surface of the grinding roller may not be affected after each scraping. Therefore, this surface treatment mechanism can detect the friction of the grinding roller. When the grinding roller is affected by oxides, the coefficient of friction changes. Only when the coefficient of friction decreases will the surface treatment mechanism spray the treatment agent to treat the surface. Furthermore, the scraper does not always contact the grinding roller; it only contacts it when the grinding roller returns to its initial state. This prevents the scraper from affecting the grinding effect if it operates simultaneously while the grinding roller is grinding the cathode roller. Thus, while ensuring the basic effect of the grinding roller, it also ensures the overall grinding effect, resulting in a better grinding outcome.

[0016] In summary, this grinding device not only focuses on treating the end of the cathode roller, but also adjusts for the increased gap caused by wear during the grinding and polishing process, ensuring that the gap between the grinding roller and the cathode roller remains constant. This allows operators to reduce the amount of adjustment needed when fine-tuning the pressure. Furthermore, since oxides may appear on the surface of the grinding roller during grinding, this device can detect the friction of the grinding roller and promptly treat its surface to ensure effective grinding.

Detailed Implementation

[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The following is combined Figures 1 to 6 As shown, this embodiment of the invention provides a secondary polishing fixture for the edge of a titanium roller, including a polishing roller for polishing the edge of the titanium roller, a drive motor for driving the polishing roller, a bearing sleeve for adjusting the angle of the polishing roller, an adjustment handle for adjusting the polishing position of the polishing roller, a rotating base for switching the position of the polishing roller away from the working range of the titanium roller, a gap adjustment mechanism for adjusting the position of the worn polishing roller to make the fine adjustment distance the same, a surface treatment mechanism for treating the surface of the polished polishing roller, and a safety plate to prevent personnel injury.

[0032] During operation, this grinding device not only focuses on treating the end of the cathode roller, but also adjusts for the increased gap caused by wear during the grinding and polishing process. This ensures that the gap between the grinding roller and the cathode roller remains constant, allowing operators to reduce the amount of adjustment needed when fine-tuning the pressure. Furthermore, since oxides may appear on the surface of the grinding roller during grinding, this device can detect the friction of the grinding roller and promptly treat its surface to ensure effective grinding.

[0033] Specifically, the surface treatment mechanism includes a scraper, a liquid replenishment box at the upper end of the scraper, a pressing block inside the liquid replenishment box, several liquid outlet holes at one end of the scraper, a mating plate inside the scraper, several through holes on the mating plate, a movable abutment block at the bottom of the scraper, a mating hydraulic rod between the movable abutment block and the inner wall of the scraper, a pushing hydraulic rod above the mating plate, and a second connecting pipe between the pushing hydraulic rod and the mating hydraulic rod.

[0034] Specifically, the contact edge of the scraper is inclined.

[0035] During operation, it facilitates the scraper to perform surface treatment on the grinding roller.

[0036] Specifically, in the initial state, the through holes and liquid outlet holes in the mating plate are misaligned.

[0037] During operation, the grinding roller is not sprayed with a treatment agent, thus ensuring the grinding effect of the grinding roller.

[0038] Specifically, the gap adjustment mechanism includes an electric telescopic rod and a slide rail. A processor and an electromagnetic flow direction switch are located in the middle of the electric telescopic rod. A slider is located below the drive motor and is slidably connected to the slide rail. An electric telescopic rod is positioned between the slider and the safety plate. A mating magnet is located below the other end of the scraper. An electromagnet is located below the mating magnet and is mounted on the safety plate. A rotating shaft is located at the lower center of the scraper. A hydraulic telescopic rod is positioned between the rotating shaft and the bottom of the scraper. A hydraulic box is located below the electromagnet, and a gravity sensor is located inside the hydraulic box. A first connecting pipe is positioned between the hydraulic telescopic rod and the hydraulic box. A control hydraulic rod is positioned between the mating magnet and the electromagnet, and the control hydraulic rod is connected to a second connecting pipe via a third connecting pipe.

[0039] Specifically, the first connecting pipe is a one-way valve pipe.

[0040] This prevents the liquid entering the hydraulic box from flowing back into the hydraulic telescopic rod, thus ensuring that the weight on the internal gravity sensor only gradually increases. At this time, the electric telescopic rod will also move continuously, preventing the electric telescopic rod from resetting and affecting subsequent work.

[0041] Specifically, the cross-section of the hydraulic telescopic rod is arc-shaped, and a return spring is provided in the hydraulic telescopic rod, the cooperating hydraulic rod, and the ejection hydraulic rod.

[0042] During operation, the internal return spring allows the components that work with the hydraulic telescopic rod, the cooperating hydraulic rod, and the ejection hydraulic rod to return to their original position, thus ensuring repeated use.

[0043] Specifically, the direction of current flow in the electromagnet is adapted to the rotation angle of the rotating base.

[0044] When in operation, according to Ampere's law, the magnetic poles of the electromagnet can be changed by changing the direction of the current. At this time, the direction of the current is related to the angle of the rotating base, thereby changing the position of the scraper.

[0045] Working Principle: During use, when an oxide layer appears at the end of the cathode roller, it needs to be polished. To do this, the rotating base is rotated to move the polishing roller to the desired polishing position (the working position). The distance between the polishing roller and the cathode roller is then fine-tuned using the adjustment handle, controlling the pressure between them. Once the polishing roller is in the working position, the drive motor is activated to rotate it, thus polishing the cathode roller. When the polishing roller is in the working position, the current direction of the electromagnet is switched by an electromagnetic flow direction switch. The electromagnet attracts the magnet, causing the scraper to deflect around the rotating axis. At this point, the scraper does not contact the polishing roller, allowing it to polish normally. After grinding, the grinding roller is moved to a non-working position. At this point, the current direction of the electromagnet changes via an electromagnetic flow direction switch. The electromagnet and its cooperating magnet repel each other, causing the scraper to deflect at an angle and contact the grinding roller surface. As the grinding roller wears down, the scraper's deflection angle increases, squeezing the hydraulic telescopic rod and forcing its internal fluid into the hydraulic box through the first connecting pipe. The gravity sensor detects this change in weight within the hydraulic box and sends feedback to the processor of the electric telescopic rod, controlling its movement. (The distance the electric telescopic rod moves is equal to the amount of fluid the scraper additionally deflects and compresses, causing it to enter the hydraulic box, thus achieving the desired deflection amount.) (Controlling the movement of the electric telescopic rod) When the telescopic end of the electric telescopic rod changes, it drives the drive motor and the grinding roller to change synchronously. At this time, although the size of the grinding roller changes, the gap between the grinding roller and the cathode roller does not change because the grinding roller is affected by the change of the electric telescopic rod. Secondly, when the grinding roller moves to the non-working position, it will still rotate. When the grinding roller generates electricity, it will rub against the movable contact block. If the friction of the grinding roller does not change, the movable extrusion block will press the hydraulic rod, causing the liquid in the hydraulic rod to enter the ejection hydraulic rod, making the hydraulic telescopic rod work. At this time, the liquid outlet hole on the scraper and the through hole on the mating plate are misaligned under the action of the ejection hydraulic rod. The system is configured so that the treatment agent cannot be discharged at this point (if the movable contact block can move, it means the surface of the front grinding roller is not affected, and the treatment agent does not need to be discharged). When the surface of the grinding roller is affected, the movable contact block does not change position, causing the liquid outlet to coincide with the through hole of the mating plate. Since the scraper is tilted at this time and affected by the pressure block in the replenishment box, the internal treatment liquid will be discharged. After grinding is completed, the current direction is manually switched. At this time, the scraper is attracted by the electromagnet, and its position changes. The mating magnet will squeeze the control hydraulic rod, causing the liquid in the control hydraulic rod to enter the ejection hydraulic rod. At this time, the mating plate blocks the liquid outlet, preventing liquid from flowing out. Therefore, although the scraper is not working, it will not discharge liquid.The outlet only opens after the product has been used and the coefficient of friction has changed.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
