Description

Technical Field

[0001] The utility model relates to the field of mechanical engineering, in particular to a porous aluminum current collector chemical etching device. Background Art

[0002] Currently, porous aluminum current collectors have been widely used in battery manufacturing, supercapacitors and various electronic devices due to their light weight, high conductivity and excellent mechanical properties. In the traditional preparation process of porous aluminum current collectors, physical stamping or laser cutting methods are usually used to form the required pore structure. However, these methods have some shortcomings. Physical stamping may cause burrs on the edge of the material, affecting the subsequent processing accuracy. Although laser cutting can achieve higher precision, it is costly and has a slow processing speed, making it unsuitable for large-scale production.

[0003] Chemical etching, an effective alternative, selectively corrodes metal surfaces using specific chemicals. This allows the creation of complex, uniformly sized microporous structures without damaging the substrate. However, existing chemical etching equipment suffers from complex operation, low automation levels, and inconsistent etching results. Research on solutions to these problems, such as ensuring smooth and accurate feeding of the material to be processed on continuous production lines while maintaining constant pressure and chemical distribution during the etching process, is of particular practical significance.

[0053] The two clamps 201 are arranged vertically, the transfer rail 207 is arranged between the two clamps 201, the two clamps 201 are respectively arranged on the two pipe clamps 202, the two sleeve bearings 203 are respectively arranged in the two pipe clamps 202, the two eccentric wheels 204 are respectively arranged in the two sleeve bearings 203, the two pipe clamps 202 are respectively connected to the two first slide bars 205 through sliders, the two ends of the first slide bars 205 are respectively connected to the two second slide bars 206 through sliders, and the transfer rail 207 and the two transfer rollers 103 are in the same plane.

[0054] As Figure 3 shown, the etching assembly 100 further includes:

[0055] Two baffles 106, the first conveyor belt 101 and the two transfer rollers 103 are respectively arranged between the two baffles 106;

[0056] A mounting seat 107, and the winding roller 104 is arranged on the mounting seat 107.

[0057] A magnetic powder brake 108, the magnetic powder brake 108 is arranged on the mounting seat 107, and the magnetic powder brake 108 is connected to the winding roller 104.

[0058] On the first mounting bracket 109, the two baffles 106, the mounting seat 107, the second conveyor belt 102 and the injector 105 are respectively arranged on the first mounting bracket 109.

[0059] As Figure 5 shown, it further includes: two belt pulleys 300, and the two belt pulleys 300 are respectively connected to the rotating shafts of the two eccentric wheels 204;

[0060] A second mounting bracket 400, and the two belt pulleys 300 are respectively arranged on the second mounting bracket 400.

[0061] As Figure 6 shown, it further includes:

[0062] Two spur gears 500, the two spur gears 500 are arranged vertically and mesh with each other;

[0063] A sector gear 600, the sector gear 600 is arranged on the rotating shaft of one of the two eccentric wheels 204, and the sector gear 600 meshes with the upper spur gear 500;

[0064] The pressing roller 700 is arranged on the conveying rail 207, and the pressing roller 700 is connected to the rotating shaft of the full gear 500 below.

[0065] The third mounting bracket 800, two gears and the sector gear 600 are respectively arranged on the third mounting bracket 800.

[0066] In the embodiment of the present utility model, the device mainly consists of an etching assembly 100 and a cutting assembly 200, and completes the processes of cutting, bonding and chemical etching of the porous aluminum current collector through the coordinated work of a series of mechanical and transmission components.

[0067] Specifically, first, the porous aluminum current collector to be processed is placed on the conveying rail 207, and the motor drives the pulley 300 to rotate, thereby driving the two eccentric wheels 204 to rotate in opposite directions. As the eccentric wheels 204 rotate, through the action of the sleeve bearing 203, the pipe clamp 202 will produce eccentric movement.

[0068] However, under the constraint of the first slide bar 205 and the second slide bar 206, this eccentric motion is converted into a reciprocating motion in the vertical direction. Therefore, the clamp 201 installed on the pipe clamp 202 also moves up and down accordingly. When the clamp 201 moves downward, they will clamp and cut the porous aluminum current collector located between them. By adjusting the rotation speed of the eccentric wheel 204, the moving speed of the clamp 201 can be controlled, and then the length of the cut porous aluminum current collector sheet can be adjusted.

[0069] The cut porous aluminum current collector sheet is conveyed to the etching assembly 100 via the conveying rail 207. In this assembly, the winding roller 104 is responsible for winding the base material, such as plastic film, etc.;

[0070] The base material starts from the winding roller 104, passes through the two conveying rollers 103, and then reaches the second conveyor belt 102. When the porous aluminum current collector sheet passes through the two conveying rollers 103, under the pressure of the first conveyor belt 101, it will be pressed and bonded to the base material.

[0071] Subsequently, the bonded material continues to move forward above the second conveyor belt 102. At this time, the injector 105 starts to spray the pre-prepared chemical agent to perform precise etching treatment on the porous aluminum current collector sheet, and finally form the required pattern or structure.

[0072] To ensure that the porous aluminum current collector is fed smoothly and accurately between the clamps 201 and maintain an appropriate feeding speed, the system is also equipped with a full gear 500, a sector gear 600, and a pressure roller 700. The shaft of one eccentric wheel 204 is connected to the sector gear 600, and the sector gear 600 meshes with the upper full gear 500. Such a design makes it so that whenever the eccentric wheel 204 rotates, the sector gear 600 periodically pushes the full gear 500 to rotate. The lower full gear 500 is directly connected to the pressure roller 700. Therefore, the pressure roller 700 also rotates intermittently, thereby achieving intermittent propulsion of the porous aluminum current collector on the conveyor rail 207.

[0073] In summary, according to the porous aluminum current collector chemical etching device disclosed in the present utility model, by adopting a cutting assembly 200 including structures such as clamps 201, pipe clamps 202, sleeve bearings 203, eccentric wheels 204, and first and second sliding rods 205 and 206, precise cutting of the porous aluminum current collector can be achieved, and the cut sheet is smoothly conveyed to the next processing stage through the conveyor rail 207, ensuring continuity and efficiency in the processing process. At the same time, through the design of the first conveyor belt 101 and the two conveyor rollers 103 in the etching assembly 100, the cut porous aluminum current collector can be closely combined with a substrate (such as a plastic film) under controlled pressure, providing a good foundation for subsequent chemical etching. At the same time, the injector 105 is located above the second conveyor belt 102, and can evenly spray chemical agents, ensuring the consistency of the etching process and improving the quality stability of the product.

[0074] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limitations of the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present utility model.
