Description

Technical Field

[0001] This utility model relates to the technical field of aluminum foil processing equipment, specifically to an aluminum foil perforation and etching device. Background Technology

[0002] With the development of miniaturization and high capacity of electronic components, the smooth surface of traditional aluminum foil (bright foil) can no longer meet the requirements of high-performance capacitors for the specific surface area of ​​electrode materials. Therefore, it is necessary to use etching and hole-expanding equipment to expand the holes of aluminum foil, thereby directional etching micron-level tunnel holes or sponge-like porous structures on the surface of aluminum foil, which increases the specific surface area by hundreds of times.

[0003] In the prior art, patent CN119101905A discloses a device and method for etching and expanding holes in an etched foil, including a working plate and a positioning device. The working plate has a placement frame fixedly mounted on its top, a U-shaped plate fixedly mounted on the front side of the placement frame, a traction device fixedly mounted on its top, an etching table fixedly mounted on its top, an etching frame fixedly mounted on its top, a placement groove formed at the top of the etching frame, a placement rod fixedly mounted inside the placement groove, a displacement device slidably mounted on the circumferential surface of the placement rod, an electric push rod fixedly passing through the top of the etching frame, an etching rod fixedly mounted at the output end of the electric push rod, and a spraying device fixedly mounted at the bottom of the displacement device, the spraying device containing an etching liquid.

[0004] Existing equipment for aluminum foil enlargement and etching has the following drawbacks: it moves the extrusion block to extrude the positioning block, which in turn moves the positioning rod and positioning frame, so that the positioning frame contacts the aluminum foil and positions the aluminum foil. However, it can only adjust the positioning of aluminum foil of a specific width, which is not very applicable. Therefore, we propose an equipment for aluminum foil enlargement and etching. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a device for enlarging and etching aluminum foil. Through an adjustment mechanism, the limiting block contacts the aluminum foil and pushes the aluminum foil, thereby positioning and correcting the aluminum foil. This ensures that the actual position of the hole is the same as the design requirement, avoiding deviations in the enlarged hole position caused by aluminum foil position deviations. Furthermore, the distance between the limiting blocks on both sides can be adjusted to adapt to aluminum foils of different widths, making it more applicable and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for enlarging and etching aluminum foil, comprising a workbench, a second support frame fixedly connected to the upper middle part of the workbench, a liquid storage tank fixedly connected to the right side inside the workbench, a first support frame fixedly connected to the left side of the upper surface of the workbench, an adjustable conductive rod provided on the lower side of the first support frame, and an adjustment mechanism.

[0007] Adjustment mechanism: It includes a slide rod, a limiting block, a connecting rod, a connecting seat, and a screw. The slide rod is slidably connected to the front and rear sides of the worktable. The side of the slide rod near the center of the worktable is fixedly connected to a limiting block. The internal thread of the support frame is connected to a screw. The lower end of the screw is rotatably connected to a connecting seat. The lower end of the connecting seat and the outer surface of the slide rod are rotatably connected to a connecting rod. Through the adjustment mechanism, the limiting block contacts the aluminum foil and pushes the aluminum foil, thereby positioning and correcting the aluminum foil. This ensures that the actual position of the hole is the same as the design requirement, avoiding deviations in the hole enlargement position due to aluminum foil position deviations. The distance between the limiting blocks on both sides can be adjusted to adapt to aluminum foils of different widths, making it more versatile.

[0008] Furthermore, a control switch is provided on the outside of the workbench. The input end of the control switch is electrically connected to an external power source, and the input end of the conductive rod is electrically connected to the output end of the control switch to control the operation of electrical appliances.

[0009] Furthermore, the adjustment mechanism also includes a fixed plate, an indicator rod, and scale lines. The fixed plate is fixedly connected to the right surface of the support frame two. An indicator rod is slidably connected inside the fixed plate. The left end of the indicator rod is fixedly connected to the right surface of the connecting seat. Scale lines are provided on the right surface of the fixed plate to indicate the distance between the limit blocks.

[0010] Furthermore, the interior of the storage tank is fixedly connected with symmetrically distributed guide rollers, and a guide groove is opened on the left surface of the storage tank to guide the aluminum foil so that the aluminum foil is completely immersed in the interior of the acidic electrolyte in the storage tank.

[0011] Furthermore, the worktable is internally fixed with symmetrically distributed fixed rollers, and an adjustable pressure roller is provided on the upper side of the fixed rollers to keep the aluminum foil taut during movement, thereby ensuring the quality of aluminum foil perforation corrosion.

[0012] Furthermore, the workbench is fixedly connected to symmetrically distributed mounting seats on both the front and rear sides. Each mounting seat is fixedly connected to a guide rod. Each guide rod has a slider slidably connected to the lower side of its outer surface. A spring is fixedly connected between the upper surface of the slider and the inner wall of the mounting seat. The spring is sleeved on the outer surface of the guide rod. The pressure roller is fixedly connected between two longitudinally adjacent sliders, so that the pressure rod automatically presses the aluminum foil, thereby adapting to various aluminum foils of different thicknesses.

[0013] Furthermore, an electric push rod is fixedly connected to the lower surface of the support frame one, and a mounting frame is fixedly connected to the lower side of the telescopic end of the electric push rod. The conductive rods are all fixedly connected to the lower surface of the mounting frame. The position of the conductive rods is adjusted to electrolytically etch the aluminum foil.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This device for aluminum foil aperture enlargement and etching has the following advantages:

[0015] The adjustment mechanism allows the limiting block to contact the aluminum foil and push it, thereby positioning and correcting the aluminum foil. This ensures that the actual position of the hole matches the design requirements, avoiding deviations in the hole enlargement position due to aluminum foil position deviations. Furthermore, the spacing between the limiting blocks on both sides can be adjusted to adapt to aluminum foils of different widths, making it more versatile. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a device for enlarging and etching aluminum foil, including a workbench 1, a support frame 2 17 fixedly connected to the upper center of the workbench 1, a liquid storage tank 2 fixedly connected to the right side of the inside of the workbench 1, guide rollers 3 symmetrically distributed fixedly connected to the inside of the liquid storage tank 2, a guide groove 4 opened on the left surface of the liquid storage tank 2, a support frame 6 fixedly connected to the left side of the upper surface of the workbench 1, an adjustable conductive rod 9 provided on the lower side of the support frame 6, fixed rollers 11 symmetrically distributed on the left and right sides of the inside of the workbench 1, an adjustable pressure roller 10 provided on the upper side of the fixed rollers 11, and mounting seats 12 symmetrically distributed on the left and right sides of the inside of the workbench 1. Guide rods 13 are fixedly connected internally. Slider blocks 14 are slidably connected to the lower outer surface of each guide rod 13. Springs 15 are fixedly connected between the upper surface of each slider 14 and the inner wall of the mounting base 12. Springs 15 are sleeved on the outer surface of the guide rods 13 (the top cover of the mounting base 12 can be removed, and the springs 15 can be replaced after removing the top cover of the mounting base 12). Pressure rollers 10 are fixedly connected between two longitudinally adjacent sliders 14. Springs 15 press sliders 14, causing sliders 14 to move downwards, thereby driving pressure rollers 10 to move downwards and press against the fixed rollers 11, keeping the aluminum foil taut during movement. A control switch 16 is provided on the outside of the worktable 1. The input of the control switch 16... The device is electrically connected to an external power source. An electric push rod 7 is fixedly connected to the lower surface of the support frame 6. A mounting frame 8 is fixedly connected to the lower side of the telescopic end of the electric push rod 7. Conductive rods 9 are all fixedly connected to the lower surface of the mounting frame 8. The input end of the electric push rod 7 is electrically connected to the output end of the control switch 16, and the input end of the conductive rods 9 is also electrically connected to the output end of the control switch 16. When using this aluminum foil enlargement and etching equipment to perform enlargement and etching operations on aluminum foil, the left end of the aluminum foil is passed through the lower side of the two guide rollers 3, inside the guide groove 4, between the vertically adjacent pressure rollers 10 and fixed rollers 11 on the right, and between the vertically adjacent pressure rollers 10 and fixed rollers 11 on the left, and then connected to an external traction device to inject liquid into the storage tank 2. An acidic electrolyte is used. When the aluminum foil passes through the acidic electrolyte, the acidic electrolyte adheres to the surface of the aluminum foil. Then, an external traction device moves the aluminum foil so that the position to be enlarged is located below the mounting frame 8. At this time, the external traction device stops running, the aluminum foil stops moving, and the control switch 16 is operated to start the electric push rod 7. The telescopic end of the electric push rod 7 extends, driving the mounting frame 8 to move downward, causing the conductive rod 9 to move downward. The conductive rod comes into contact with the surface of the aluminum foil, and the acidic electrolyte reacts with the aluminum foil to undergo an oxidation reaction. Under the drive of the current, the aluminum foil substrate is oriented to etch, forming an etched hole. Then, the telescopic end of the electric push rod 7 is shortened and reset. This process is repeated to perform the hole enlargement and etching operation on the aluminum foil. The system also includes an adjustment mechanism 5.

[0023] Adjustment mechanism 5 includes a slide rod 51, a limiting block 52, a connecting rod 53, a connecting seat 54, and a screw 55. The slide rod 51 is slidably connected to the front and rear sides of the inside of the worktable 1. The side of the slide rod 51 closest to the middle of the worktable 1 is fixedly connected to the limiting block 52. The screw 55 is threadedly connected to the inside of the support frame 2 17 (corrugated tubes are fixedly connected between the upper and lower surfaces of the support frame 2 17 and between the lower surface of the support frame 2 17 and the upper surface of the connecting seat 54. The corrugated tubes are all sleeved on the outer surface of the screw 55 to protect the screw 55 and prevent external impurities from sticking to the outer surface of the screw 55 and causing the screw 55 to jam). The lower end of the screw 55 is rotatably connected to the connecting seat 54. The lower end of the connecting seat 54 and the outer surface of the slide rod 51 are rotatably connected to the connecting rod 53. The adjustment mechanism 5 also includes a fixing plate 56 and a finger. The indicator rod 57 and scale line 58 are fixedly connected to the right surface of the support frame 17 by the fixing plate 56. The indicator rod 57 is slidably connected inside the fixing plate 56. The left end of the indicator rod 57 is fixedly connected to the right surface of the connecting seat 54. The scale line 58 is opened on the right surface of the fixing plate 56. Rotating the screw 55 causes the screw 55 to rotate and move vertically, which drives the connecting seat 54 to move up and down, and drives the connecting rod 53 to move, so that the sliding rods 51 on the front and rear sides move synchronously towards each other or opposite each other, thereby driving the limiting blocks 52 to move synchronously towards each other or opposite each other, thereby limiting and guiding the aluminum foil. At the same time, the movement of the connecting seat 54 drives the indicator rod 57 to move up and down. According to the position of the scale line 58 corresponding to the indicator rod 57, the spacing of the limiting blocks 52 on both sides is adjusted so that the spacing between the limiting blocks 52 is the same as the width of the aluminum foil, thereby accurately limiting and adjusting the aluminum foil.

[0024] The working principle of the aluminum foil enlargement and etching equipment provided by this utility model is as follows: When using this equipment to enlarge and etch aluminum foil, the left end of the aluminum foil passes through the lower side of two guide rollers 3, the inside of the guide groove 4, between the vertically adjacent pressure rollers 10 and fixed rollers 11 on the right side, and between the vertically adjacent pressure rollers 10 and fixed rollers 11 on the left side. Then, it is connected to an external traction device. Rotating the screw 55 causes it to rotate and move vertically, driving the connecting seat 54 to move up and down, which in turn moves the connecting rod 53. This causes the sliding rods 51 on both sides to move synchronously towards or opposite each other, thereby driving the limiting blocks 52 to move synchronously towards or opposite each other, thus limiting and guiding the aluminum foil. Simultaneously, the movement of the connecting seat 54 causes the indicator rod 57 to move up and down. Based on the position of the scale line 58 corresponding to the indicator rod 57, the spacing between the limiting blocks 52 on both sides is adjusted so that the spacing between the limiting blocks 52 is the same as the width of the aluminum foil. This allows for precise positioning and adjustment of the aluminum foil. Spring 15 presses slider 14, causing slider 14 to move downwards, which in turn moves pressure roller 10 downwards and presses it against fixed roller 11, keeping the aluminum foil taut during movement. Acidic electrolyte is injected into the storage tank 2. When the aluminum foil passes through the acidic electrolyte, the acidic electrolyte adheres to the surface of the aluminum foil. Then, external traction equipment moves the aluminum foil so that the position to be enlarged is located below the mounting frame 8. At this point, the external traction equipment stops running, and the aluminum foil stops moving. The control switch 16 is operated to start the electric push rod 7. The telescopic end of the electric push rod 7 extends, causing the mounting frame 8 to move downwards, which in turn moves the conductive rod 9 downwards. The conductive rod contacts the surface of the aluminum foil, and the acidic electrolyte reacts with the aluminum foil to oxidize it. Under the drive of the current, the aluminum foil substrate is etched in a directional manner to form an etched hole. Then, the telescopic end of the electric push rod 7 is shortened and reset. This process is repeated to perform the enlarged hole etching operation on the aluminum foil.

[0025] It is worth noting that the electric push rod 7 disclosed in the above embodiments is HDJ300, and the control switch 16 is provided with a control button corresponding to the electric push rod 7 and used to control its switch.

[0026] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
