Description
Technical Field
[0001] This utility model belongs to the field of aluminum foil corrosion production technology, and specifically relates to an auxiliary positioning device for a medium and high voltage electronic aluminum foil corrosion production line. Background Technology
[0002] Currently, in the field of medium and high voltage electronic aluminum foil etching production, the pressure roller, as a core component guiding the aluminum foil precisely into the electrolytic cell, directly affects the stability of the aluminum foil etching process and product quality. In existing technologies, the pressure roller is usually rotatably connected to the inside of the electrolytic cell in a fixed manner. For example, the electrolytic cell device disclosed in patent publication number "CN211112311U" adapts to different aluminum foil sizes through the telescopic design of the positioning roller, but still adopts a fixedly installed conveying pressure roller and exiting pressure roller structure.
[0003] This type of structure has significant drawbacks: First, the fixed installation position of the pressure roller makes it impossible to dynamically adjust the immersion depth in the electrolytic cell based on process parameters such as aluminum foil thickness and electrolyte concentration. This makes it difficult to optimize the contact angle and area between the aluminum foil and the electrolyte, affecting corrosion uniformity. Second, the lack of a positioning device at the end of the pressure roller means that when the aluminum foil is conveyed at high speed, its lateral displacement on the roller surface cannot be effectively constrained, leading to lateral movement and causing the aluminum foil to deviate from the preset path, severely reducing the accuracy of centering and conveying. These problems not only reduce the stability of the corrosion process but may also cause surface damage due to friction between the aluminum foil and the electrode plate, restricting the production efficiency and yield of medium and high voltage electronic aluminum foil. Therefore, the existing technology has certain defects and shortcomings, necessitating improved design. Utility Model Content
[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an auxiliary positioning device for a medium and high voltage electronic aluminum foil etching production line to solve the problems raised in the background art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] An auxiliary positioning device for a medium- and high-voltage electronic aluminum foil etching production line includes a pool body, a positioning mechanism fixedly installed in the middle of the pool body, side guide rollers fixedly installed at both ends inside the pool body, and side guide rollers rotatably connected to both sides of the top of the pool body.
[0007] The positioning mechanism includes a guide rail, which is fixedly installed in the middle of the front and back of the pool body. A drive motor is fixedly installed at the bottom of the rear guide rail. A lead screw is fixedly installed through the output end of the drive motor through the guide rail. A slide is threaded to the outer surface of the lead screw. The slide is slidably connected to the inside of the guide rail. A sliding plate is slidably connected to the inside of the front guide rail. A positioning component is provided between the upper end of the sliding plate and the inner side of the upper end of the slide.
[0008] As a preferred technical solution, a top frame is fixedly installed on the top of the pool body, and support legs are fixedly installed at the four corners of the bottom of the top frame.
[0009] As a preferred technical solution, a support base is fixedly installed at the bottom of the support leg, and the bottom of the support base is provided with anti-slip stripes.
[0010] As a preferred technical solution, the top view shape of the guide rail is set to a convex shape, and the top view shapes of the carriage and the slide are also set to a convex shape.
[0011] As a preferred technical solution, a drain valve is fixedly connected to the bottom center of the pool body, and the input end of the drain valve is connected to the interior of the pool body.
[0012] As a preferred technical solution, the positioning component includes a side arm, which is fixedly installed on the upper inner side of the carriage and the slide plate. A buffer spring is fixedly installed at the bottom of the side arm, and a connecting arm is fixedly installed at the bottom of the buffer spring. A pressure roller is rotatably connected to the lower inner side of the connecting arm. Limiting discs are movably installed at both ends of the pressure roller and the side guide roller. A damper is fixedly connected between the inner sides of the side arm and the connecting arm, and the buffer spring is sleeved on the outer side of the damper.
[0013] As a preferred technical solution, the limiting disc assembly includes a slip ring, which is slidably connected to both ends of the pressure roller and the side guide roller. A limiting ring disc is fixedly installed on the inner side of the slip ring, and a fixing block is fixedly installed on both ends of the outer side of the slip ring. A mounting screw is threaded to the outer end of the fixing block, and the end of the mounting screw passes through the fixing block. The mounting screw is a hand-tightening screw.
[0014] In summary, the present invention has the following main advantages:
[0015] First, this auxiliary positioning device drives the slide and slide plate to move vertically via a lead screw, precisely adjusting the depth of the pressure roller immersed in the electrolytic cell. It can adapt to aluminum foil of different thicknesses and electrolyte concentrations. At the same time, the limiting discs at both ends of the pressure roller and the side guide roller can be adjusted by hand-tightening the installation screws to effectively constrain the lateral displacement of the aluminum foil. The two work together to ensure that the aluminum foil is conveyed centered along the preset path, avoiding deviation and friction with the electrode plate, reducing surface damage, and keeping the contact angle and area between the aluminum foil and the electrolyte in the optimal state. This significantly improves corrosion uniformity and conveying accuracy, and reduces the scrap rate.
[0016] Secondly, the positioning component of this device adopts a design combining buffer springs and dampers. When the thickness of the aluminum foil changes or pressure is generated during transmission, the buffer spring can be compressed to make the pressure roller move vertically, playing a buffering role and preventing the aluminum foil from breaking accidentally due to rigid extrusion. The damper suppresses spring oscillation, allowing the pressure roller to quickly stabilize in the appropriate position. In addition, the convex guide rail, slide, and slide plate structure enhance the overall stability and ensure a smooth adjustment process for the pressure roller. The coordinated action of multiple components not only improves the stability of aluminum foil transmission but also optimizes its contact state with the electrolyte, ensuring the smooth progress of the corrosion process and extending the service life of the equipment.

[0023] Example
[0024] refer to Figures 1 to 5 The auxiliary positioning device for a medium- and high-voltage electronic aluminum foil etching production line in this embodiment includes a pool body 1, a positioning mechanism 2 fixedly installed in the middle of the pool body 1, side guide rollers 3 fixedly installed at both ends inside the pool body 1, and side guide rollers 4 rotatably connected to both sides of the top of the pool body 1.
[0025] The positioning mechanism 2 includes a guide rail 21, which is fixedly installed in the middle of the front and back sides of the tank body 1. A drive motor 22 is fixedly installed at the bottom of the rear guide rail 21. A lead screw 23 is fixedly installed through the guide rail 21 at the output end of the drive motor 22. A slide 24 is threaded onto the outer surface of the lead screw 23 and slidably connected to the inside of the guide rail 21. A sliding plate 25 is slidably connected to the inside of the front guide rail 21. A positioning component 26 is provided between the upper end of the sliding plate 25 and the inner side of the upper end of the slide 24. During use, in the aluminum foil corrosion production process, this auxiliary positioning device operates based on the tank body 1. The side guide rollers 3 at both ends of the tank body 1 and the side guide rollers 4 on both sides of the top provide initial guidance to the aluminum foil, guiding it into the electrolytic cell. When it is necessary to adjust the immersion depth of the pressure roller 264 in the electrolytic cell, the drive motor 22 located at the bottom of the rear guide rail 21 is started. The output end of the drive motor 22 drives the lead screw 23 to rotate. Since the lead screw 23 is connected to the slide 24 by a thread, according to the principle of screw transmission, the rotational motion of the lead screw 23 is converted into the vertical linear motion of the slide 24 along the guide rail 21. The slide plate 25 in the front guide rail 21 slides synchronously with the slide 24. The positioning component 26 between the upper end of the slide plate 25 and the inner side of the upper end of the slide 24 moves vertically accordingly, thereby realizing the adjustment of the immersion depth of the pressure roller 264. Through this series of structural coordination, the position of the pressure roller 264 can be precisely adjusted according to process parameters such as aluminum foil thickness and electrolyte concentration, providing a stable conveying and positioning basis for the aluminum foil corrosion process.
[0026] refer to Figures 1-4 A top frame 5 is fixedly installed on the top of the pool body 1. Support legs 6 are fixedly installed at the four corners of the bottom of the top frame 5. A support base 7 is fixedly installed at the bottom of the support legs 6. The bottom of the support base 7 is provided with anti-slip stripes. The top view shape of the guide rail 21 is set as a convex shape. The top view shape of the slide 24 and the slide plate 25 is also set as a convex shape. A drain valve 8 is fixedly connected to the bottom center of the pool body 1. The input end of the drain valve 8 is connected to the inside of the pool body 1. During the application of this device, the top frame 5 fixed on the top of the pool body 1 is connected to the support base 7 through the support legs 6 at the four corners. The anti-slip stripes on the bottom of the support base 7 can increase the friction with the ground and prevent the device from vibrating during production. Displacement due to factors such as movement ensures the stability of the overall structure; the guide rail 21, slide 24 and slide plate 25 all adopt a convex design. This structure utilizes the convex groove of the guide rail 21 to cooperate with the convex structure of the slide 24 and slide plate 25, which can effectively limit the slide 24 and slide plate 25 from disengaging from the guide rail 21 laterally during vertical movement, ensuring the stability and accuracy of the vertical adjustment of the pressure roller 264 in the positioning mechanism 2; the drain valve 8 in the middle of the bottom of the pool 1 is connected to the inside of the pool 1. When it is necessary to replace or drain the electrolyte, opening the drain valve 8 will allow the electrolyte in the pool 1 to flow out, which is convenient for maintaining the cleanliness and concentration stability of the electrolyte in the electrolytic cell and ensuring the normal operation of the corrosion process.
[0027] refer to Figures 2-4 The positioning assembly 26 includes a side arm 261, which is fixedly installed on the upper inner side of the slide 24 and the slide plate 25. A buffer spring 262 is fixedly installed at the bottom of the side arm 261, and a connecting arm 263 is fixedly installed at the bottom of the buffer spring 262. A pressure roller 264 is rotatably connected to the lower inner side of the connecting arm 263. Limiting discs 265 are movably installed at both ends of the pressure roller 264 and the side guide roller 3. A damper 266 is fixedly connected between the inner sides of the side arm 261 and the connecting arm 263, and the buffer spring 262 is sleeved on the outer side of the damper 266. During the application of this device, in its positioning assembly 26, the side arm 261 is fixed on the upper inner side of the slide 24 and the slide plate 25, the buffer spring 262 at its bottom is connected to the connecting arm 263, the lower inner side of the connecting arm 263 is rotatably connected to the pressure roller 264, and the damper 266 is fixed to the side arm 261. A buffer spring 262 is sleeved between the inner and outer sides of the connecting arm 263. When the aluminum foil is conveyed, if the thickness changes or is subjected to pressure, the pressure roller 264 is forced to drive the connecting arm 263 to compress the buffer spring 262, causing the pressure roller 264 to move up and down in the vertical direction. The buffer spring 262 plays a buffering role through elastic deformation, preventing the aluminum foil from breaking due to rigid compression. At the same time, the damper 266 suppresses the oscillation of the buffer spring 262, so that the pressure roller 264 can be quickly stabilized in a suitable position, ensuring that the contact angle and area between the aluminum foil and the electrolyte are optimized. In addition, the limiting disc assembly 265 at both ends of the pressure roller 264 and the side guide roller 3 can change the spacing of the limiting ring disc 2652 by adjusting the hand-tightening installation screw 2654, thus constraining the lateral displacement of the aluminum foil. In conjunction with the buffer spring 262 and the damper 266, precise positioning and buffer protection of the aluminum foil are achieved, ensuring the stability of the corrosion process.
[0028] refer to Figures 1-2 and Figure 5The limiting disc assembly 265 includes a slip ring 2651, which is slidably connected to both ends of the pressure roller 264 and the side guide roller 3. A limiting ring disc 2652 is fixedly installed on the inner side of the slip ring 2651, and a fixing block 2653 is fixedly installed on both ends of the outer side of the slip ring 2651. A mounting screw 2654 is threaded to the outer end of the fixing block 2653, and the end of the mounting screw 2654 passes through the fixing block 2653. The mounting screw 2654 is a hand-tightening screw. During the application of this device, when the limiting disc assembly 2655 is working, the slip ring 2651 is sleeved on both ends of the pressure roller 264 and the side guide roller 3 and can slide along the roller body. The inner limiting ring disc 2652 moves synchronously with the slip ring 2651, and the hand-tightening screw on the fixing block 2653 at both ends moves synchronously with the slip ring 2651. The mounting screw 2654 passes through the fixing block 2653 and forms a threaded connection with the roller body. When it is necessary to constrain the lateral displacement of the aluminum foil, the operator adjusts the relative position of the fixing block 2653 and the roller body by turning the mounting screw 2654, which drives the slip ring 2651 and the limiting ring disc 2652 to move on the roller body, thereby changing the distance between the two limiting ring discs 2652. This distance can be precisely adjusted according to the width of the aluminum foil. When the aluminum foil is conveyed at high speed, the two limiting ring discs 2652 form a physical limiting boundary to prevent the aluminum foil from moving left and right on the roller surface, ensuring that the aluminum foil is always conveyed in the center along the central axis of the roller body. This effectively solves the problem of insufficient conveying accuracy caused by aluminum foil offset in the existing technology. At the same time, the hand-tightening screw design facilitates quick on-site adjustment and improves production adaptability.
[0029] Operating principle and advantages: This auxiliary positioning device is based on the pool body 1. A positioning mechanism 2 is installed in the middle of the pool body 1, side guide rollers 3 are set at both ends, and side guide rollers 4 are installed on both sides of the top. A top frame 5 is fixed to the top of the pool body 1. The top frame 5 is stably supported by support legs 6 and a support base 7. The anti-slip stripes on the bottom of the support base 7 can prevent the device from shifting during use. A drain valve 8 is set in the middle of the bottom of the pool body 1 to facilitate the replacement and discharge of electrolyte, maintaining the cleanliness and concentration stability of the electrolyte in the electrolytic cell. During use, after the drive motor 22 located at the bottom of the guide rail 21 on the rear side of the pool body 1 is started, the output end drives the lead screw 23 to rotate. Since the lead screw 23 and the slide 24 are connected by threads, according to the principle of screw transmission, the rotational motion of the lead screw 23 is converted into the vertical linear motion of the slide 24 along the guide rail 21. The slide plate 25 inside the front guide rail 21 slides synchronously with the carriage 24. The two are connected by the positioning component 26, thereby realizing the vertical displacement adjustment of the pressure roller 264 in the positioning component 26, thus changing the depth of the pressure roller 264 immersed in the electrolytic cell. The guide rail 21, carriage 24 and slide plate 25 all adopt a convex design. This structure can effectively prevent the carriage 24 and slide plate 25 from detaching from the guide rail 21 during movement, enhance the stability and reliability of the positioning mechanism 2, and ensure the accuracy of the movement of the positioning component 26. During use, the side arm 261 in the positioning component 26 is fixed to the upper inner side of the carriage 24 and slide plate 25. The side arm 261 is connected to the connecting arm 263 through the buffer spring 262. The lower inner end of the connecting arm 263 is rotatably connected to the pressure roller 264. When the thickness of the aluminum foil changes, the pressure generated by the contact between the aluminum foil and the pressure roller 264 will compress the buffer spring 262, causing the pressure roller 264 to move up and down in the vertical direction. During the up-and-down movement of the pressure roller 264 driven by the adjustment screw 23 of the drive motor 22, the tension buffer is assisted to improve the stability of conveying aluminum foil. At the same time, the damper 266 can suppress the oscillation of the buffer spring 262, so that the pressure roller 264 can be quickly stabilized in a suitable position, ensuring the optimization of the contact angle and area between the aluminum foil and the electrolyte, improving the corrosion uniformity. In addition, the design of the buffer spring 262 can play a good buffering role as a whole, avoiding the accidental breakage of the aluminum foil. The limiting plate group 265 installed at both ends of the pressure roller 264 and the side guide roller 3 consists of a slip ring 2651, a limiting ring plate 2652, a fixing block 2653 and a mounting screw 2654. The slip ring 2651 can slide at both ends of the pressure roller 264 and the side guide roller 3. By adjusting the hand-tight mounting screw 2654, the relative position between the fixing block 2653 and the roller body can be changed, thereby adjusting the spacing of the limiting ring plate 2652.
[0030] When the aluminum foil is conveyed at high speed, the limiting ring 2652 can effectively constrain the lateral displacement of the aluminum foil on the roller surface, preventing the aluminum foil from moving left and right, ensuring that the aluminum foil is conveyed centered along the preset path, and improving the conveying accuracy. The side guide rollers 4 are installed on both sides of the top of the tank 1, and the side guide rollers 3 are installed at both ends inside the tank 1. During the aluminum foil conveying process, the side guide rollers 4 and 3, together with the pressure roller 264 in the positioning mechanism 2, form a stable guiding system. The side guide rollers 4 and 3 can initially guide the aluminum foil into the electrolytic cell, while the positioning mechanism 2 performs precise positioning and depth adjustment of the aluminum foil. The three work together to ensure the stability of the aluminum foil conveying in the electrolytic cell and the smooth progress of the corrosion process. The dynamic adjustment function of the positioning mechanism 2 allows the pressure roller 264 to adjust the immersion depth in real time according to parameters such as aluminum foil thickness and electrolyte concentration, ensuring that the contact state between the aluminum foil and the electrolyte is always optimal, avoiding uneven corrosion caused by unreasonable contact angle and area, and improving product quality. The consistent quality is ensured by the effective constraint of the limit plate assembly 265 on the lateral displacement of the aluminum foil on the roller surface, preventing foil deviation. Combined with the side guide rollers 4 and 3, this allows the aluminum foil to be precisely conveyed along the preset path, reducing surface damage caused by foil deviation and friction with the electrode plate, thus lowering the scrap rate. This device reduces the number of downtime adjustments due to unstable aluminum foil conveying and uneven corrosion, shortening the production cycle, improving the production efficiency of medium and high voltage electronic aluminum foil, and reducing production costs. The design of the convex guide rail 21, slide 24, and slide plate 25, as well as the application of components such as dampers 266 and buffer springs 262, enhance the stability and reliability of the overall structure of the device, extend the service life of the equipment, and reduce maintenance costs. The limit plate assembly 265 uses a hand-tightening installation screw 2654, allowing operators to quickly adjust the spacing of the limit ring 2652 according to actual production needs, improving the ease of operation and adaptability of the equipment.
