Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stabilization device technology, specifically relating to an electroplating tank edge support device. Background Technology
[0002] In the field of electrolytic cell structure technology, polypropylene (PP) sheets are commonly used as insulation and sealing components for the cell edges. However, the existing installation structure of PP sheets for cell edges has the following significant drawbacks:
[0003] 1. Deformation problem caused by insufficient support: Due to the lack of rigid support structure, the edges of the PP sheet at the tank edge are prone to plastic deformation and sinking under long-term electrolyte pressure and thermal cycling. This deformation further causes a height deviation between the outer end and the inner end of the V-shaped seat connected to it (the outer end is lower than the inner end), resulting in inaccurate overall levelness of the electrolytic cell, affecting sealing performance and tank stability.
[0004] 2. Defects in conductive connection reliability: Insufficient geometric matching accuracy or excessive surface roughness at the contact interface between the V-shaped bracket and the copper head of the hanger can easily lead to increased local contact resistance. Under high voltage and high current conditions, overheating of the contact point can easily cause ablation and carbonization, resulting in abnormal fluctuations in system voltage. Statistics show that such poor contact can cause overvoltage protection devices to trigger alarms 6-8 times per shift, not only exacerbating equipment wear and tear but also frequently interrupting production processes, severely restricting production efficiency and operational safety.
[0005] There is a need for a simple and easy-to-operate support structure for supporting the edge of the electroplating tank. This utility model attempts to solve or at least alleviate the problem of easy deformation of the edge of the electroplating tank by providing an electroplating tank edge support device. Utility Model Content
[0006] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides an electroplating tank edge support device, which has the advantage of being able to conveniently provide support for the edge of the electroplating tank.
[0007] To achieve the above objectives, this utility model provides an electroplating tank edge support device, comprising: a base plate, a first folding rod disposed above the base plate, the top surface of the base plate and one end of the first folding rod being connected by a first hinge, the other end of the first folding rod being connected to one end of a second folding rod via a pivot, the other end of the second folding rod being provided with a second hinge, a fixing plate being provided on the side of the second hinge, the fixing plate having a hole with an internal thread inside the hole, a threaded rod passing through the hole, and the threaded rod being rotatably mounted on the second hinge.
[0008] As a further improvement of this utility model, a top plate is also provided at the top of the connection between the first folding rod and the second folding rod, and the top plate and the bottom plate are connected by a telescopic rod.
[0009] As a further improvement of this utility model, the telescopic rod is provided with two rods.
[0010] As a further improvement of this utility model, a handwheel is provided at the end of the threaded rod.
[0011] As a further improvement of this utility model, the threaded rod is fitted with a limiting nut, which is located on the side of the fixing plate near the second hinge, and the internal thread direction of the threaded rod is opposite to that of the fixing plate.
[0012] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:
[0013] This utility model's electroplating tank edge support device significantly improves the stability and adjustability of the tank edge support through the synergistic action of a folding rod and a threaded adjustment mechanism. The folding rod, through a hinge and rotating shaft forming a multi-stage linkage structure, can flexibly adjust the support angle according to the degree of tank deformation, effectively dispersing electrolyte pressure and thermal stress, and preventing plastic deformation caused by localized stress concentration in the PP sheet. The reverse thread engagement between the threaded rod and the fixed plate, along with an additional limiting nut, allows for bidirectional locking during fine-tuning of the support height, ensuring precise and controllable support position and preventing support failure due to vibration or load changes during operation. The combined design of the top plate and telescopic rod increases the contact area, evenly transmitting the support force to the tank edge while limiting horizontal displacement, solving the problem of secondary deformation caused by stress concentration in traditional rigid support devices. This device adopts a modular assembly method, allowing for disassembly and maintenance without complex tools, adapting to the installation requirements of electrolytic cells of different specifications, and significantly reducing downtime for maintenance. This device can significantly reduce the sinking of the tank edge, ensure that the inner and outer sides of the V-shaped seat are horizontal, and make full contact with the copper head of the hanger, resulting in good conductivity. The temperature rise at the V-shaped seat contact point is significantly reduced, and the frequency of overvoltage alarms is significantly reduced, from 6-8 times per shift to 0 times per shift. This significantly improves the operational stability and production efficiency of the electrolytic cell, while also extending the service life of the sealing components and conductive parts.

[0020] 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.
[0021] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.
[0022] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.
[0023] In the embodiments, by Figure 1-2 Give, Figure 1 This is a schematic diagram of an electroplating tank side support device of the present invention. It can be seen that the top plate 14 is placed above the rotating shaft 4. The bottom surface of the top plate 14 is connected to the top surface of the bottom plate 1 through the telescopic rod 13. The top surface of the bottom plate 1 is also provided with a fixing plate 7. A threaded rod 8 is passed through the fixing plate 7. Rotating the threaded rod 8 can lift or lower the top plate 14. The arrangement of the rotating shaft 4, the first hinge 2, and the second hinge 6 ensures that the first folding rod 3 and the second folding rod 5 can both rotate around the end.
[0024] Figure 2 This is a cross-sectional schematic diagram of the shaft hole structure of this utility model. It can be seen that the shaft hole 11 is located at the rear end of the second hinge 6, and the limiting end 12 is rotatably set in the shaft hole 11 to ensure that the threaded rod 8 will not disengage from the second hinge 6 when it moves horizontally.
[0025] An electroplating tank edge support device includes: a base plate 1, a first folding rod 3 disposed on the top of the base plate 1, the top surface of the base plate 1 and one end of the first folding rod 3 being connected by a first hinge 2, the other end of the first folding rod 3 being connected to one end of a second folding rod 5 via a pivot 4, the other end of the second folding rod 5 being provided with a second hinge 6, a fixing plate 7 being provided on the side of the second hinge 6, the fixing plate 7 having a hole with an internal thread inside the hole, and a threaded rod 8 passing through the hole, the threaded rod 8 being rotatably mounted on the second hinge 6.
[0026] The second hinge 6 has a shaft hole 11 at its rear end, and the threaded rod 8 has a limiting end 12 at its front end. The limiting end 12 can rotate within the shaft hole 11. Since the fixed plate 7 is fixed, the threaded rod 8 can move horizontally under the action of the internal and external threads when it rotates. When the threaded rod 8 pushes the second hinge 6 forward, the angle between the first folding rod 3 and the second folding rod 5 becomes smaller, thereby raising the position of the pivot 4 and achieving the supporting effect. When the threaded rod 8 pulls the second hinge 6 backward, the angle between the first folding rod 3 and the second folding rod 5 becomes larger, and the position of the pivot 4 decreases, thereby releasing the support.
[0027] In a preferred embodiment of this utility model, a top plate 14 is further provided at the top of the connection between the first folding rod 3 and the second folding rod 5. The top plate 14 and the bottom plate 1 are connected by a telescopic rod 13. The top plate 14 reduces the pressure on the electroplating tank when supporting upwards, resulting in a larger support area and more stable support. At the same time, the telescopic rod 13 ensures that the top plate 14 does not shift in the horizontal direction.
[0028] In a preferred embodiment of this invention, two telescopic rods 13 are provided. The use of two telescopic rods 13 further ensures that the top plate 14 does not shift. The telescopic rods 13 do not provide the lifting or lowering power to the top plate 14; they are only used to limit the horizontal displacement of the top plate 14.
[0029] In a preferred embodiment of this utility model, a handwheel 9 is provided at the end of the threaded rod 8. Rotating the handwheel 9 enables the threaded rod 8 to rotate, and the handwheel 9 facilitates the rotation of the threaded rod 8.
[0030] In a preferred embodiment of this invention, the threaded rod 8 is fitted with a limiting nut 10, which is located on the side of the fixing plate 7 near the second hinge 6. The internal thread direction of the threaded rod 8 is opposite to that of the fixing plate 7. By setting the limiting nut 10 on the threaded rod 8, the limiting nut 10 and the fixing plate 7 work together to limit the threaded rod 8, ensuring that it does not rotate unnecessarily during the support process.
[0031] In summary, the electroplating tank edge support device of this invention significantly improves the stability and adjustability of the tank edge support through the synergistic action of the folding rod and the threaded adjustment mechanism. The folding rod, through a hinge and rotating shaft forming a multi-stage linkage structure, can flexibly adjust the support angle according to the degree of tank deformation, effectively dispersing electrolyte pressure and thermal stress, and preventing plastic deformation of the PP sheet due to localized stress concentration. The reverse thread engagement between the threaded rod and the fixed plate, along with the addition of a limiting nut, allows for bidirectional locking during fine-tuning of the support height, ensuring precise and controllable support position and preventing support failure due to vibration or load changes during operation. The combined design of the top plate and telescopic rod increases the contact area, evenly transmitting the support force to the edge of the tank while limiting horizontal displacement, solving the problem of secondary deformation caused by stress concentration in traditional rigid support devices. This device adopts a modular assembly method, allowing for disassembly and maintenance without complex tools, adapting to the installation requirements of electrolytic cells of different specifications, and significantly reducing downtime for maintenance. This device can significantly reduce the sinking of the tank edge, ensure that the inner and outer sides of the V-shaped seat are horizontal, and make full contact with the copper head of the hanger, resulting in good conductivity. The temperature rise at the V-shaped seat contact point is significantly reduced, and the frequency of overvoltage alarms is greatly reduced from 6-8 times / shift to 0 times / shift. This significantly improves the operational stability and production efficiency of the electrolytic cell, while also extending the service life of the sealing components and conductive parts.
