Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular to an electroplating device. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to deposit a layer of metal film on the surface of a conductor. It is widely used in industries such as electronics, automobiles, and precision instruments. The demand for precise electroplating of complex shapes or specific parts is increasing.

[0003] An electroplating apparatus is available for continuous or batch electroplating of sheet, strip, or thin plate materials. These materials are generally conveyed forward in an electroplating tank by rollers. The anode is positioned below the material to be electroplated, and the material is connected to the cathode. The electroplating solution passes over the anode and reaches the lower surface of the material to be electroplated, thereby electroplating the lower surface of the material.

[0004] Some items to be electroplated require electroplating on both the top and bottom surfaces. Because these items are long and thin, they are difficult to flip over or are easily damaged during the flipping process. As a result, there is a lack of an electroplating device that can directly electroplat the top surface of such items. Utility Model Content

[0005] The main purpose of this invention is to provide an electroplating device for electroplating the upper surface of an object to be electroplated.

[0006] To achieve the above objectives, the electroplating apparatus proposed in this utility model includes:

[0007] A receiving assembly having a receiving slot with an opening, the receiving slot having two opposing sidewalls;

[0008] A roller assembly includes a support roller and a pressure roller, the pressure roller being disposed above and abutting against the support roller, at least one of the support roller and the pressure roller having a flexible outer wall, allowing the object to be electroplated to be movably passed between the support roller and the pressure roller, the roller assembly being provided in two sets, the two sets of roller assemblies being disposed opposite each other above the opening, each support roller being close to one of the side walls;

[0009] An electrode assembly is disposed between the two pressure rollers; and

[0010] Each of the sidewalls is provided with a liquid-blocking assembly, and the liquid-blocking assembly extends toward the corresponding idler roller, so that the receiving assembly, the two liquid-blocking assemblies and the two sets of roller assemblies together surround and form an electroplating space for receiving electroplating solution.

[0011] In one embodiment, the liquid-blocking assembly includes a liquid-blocking element made of a flexible material. One end of the liquid-blocking element is fixed to the side wall, and the other end of the liquid-blocking element abuts against the roller near the side wall, such that the receiving assembly, the two liquid-blocking elements, and the two sets of roller assemblies together surround and form an electroplating space for receiving electroplating solution.

[0012] In one embodiment, the liquid-blocking assembly further includes a fastener, by which the liquid-blocking member is fixed to the sidewall near the opening; and / or,

[0013] The liquid-blocking component has a first end and a second end. The first end is connected to the side wall, and the second end abuts against the roller. The liquid-blocking component is inclined such that the distance between the second end and the bottom wall of the receiving tank is greater than the distance between the first end and the bottom wall of the receiving tank.

[0014] In one embodiment, the pressure roller has the flexible outer wall, and the idler roller has the rigid outer wall.

[0015] In one embodiment, the electroplating apparatus further includes a liquid inlet assembly, one end of which is located outside the electroplating space, and the other end of which extends into the interior of the electroplating space for introducing electroplating solution into the electroplating space.

[0016] In one embodiment, the liquid inlet assembly includes a first liquid inlet pipe, one end of which is located outside the receiving tank, and the other end of which extends into the receiving tank. The first liquid inlet pipe is provided with a first liquid inlet hole, through which the electroplating solution enters the interior of the electroplating space.

[0017] In one embodiment, at least two first inlet holes are provided at axial intervals along the first inlet pipe; and / or,

[0018] At least two first liquid inlet holes are provided at intervals along the circumference of the first liquid inlet pipe.

[0019] In one embodiment, the liquid inlet assembly further includes a second liquid inlet pipe, one end of which is located outside the electroplating space and communicates with the first liquid inlet pipe, and the other end of which extends above the electrode assembly. The second liquid inlet pipe is provided with a second liquid inlet hole, through which the electroplating solution enters the interior of the electroplating space from the second liquid inlet pipe.

[0020] In one embodiment, the inner diameter of the second inlet pipe is smaller than the inner diameter of the first inlet pipe.

[0021] In one embodiment, the electroplating apparatus further includes a support roller disposed between the two support rollers for supporting the object to be electroplated.

[0022] The electroplating apparatus of this utility model includes a receiving assembly, an electrode assembly, two sets of roller assemblies, and two liquid-blocking assemblies. The receiving assembly is provided with a receiving groove, and the two sets of roller assemblies are arranged opposite each other above the opening of the receiving groove. Each set of roller assemblies includes a support roller and a pressure roller. The pressure roller is located above the support roller and abuts against the support roller. At least one of the support roller and the pressure roller has a flexible outer wall with a certain elasticity, which can adapt to the shape of the object to be electroplated and produce a certain deformation, so that the object to be electroplated can pass between the support roller and the pressure roller. This allows the roller assembly to transport the object to be electroplated and ensures a good seal between the object to be electroplated and the roller assembly, preventing the electroplating liquid from flowing out along the object to be electroplated. Two liquid-blocking components are each mounted on a side wall and extend towards the rollers. This allows the receiving component, the two liquid-blocking components, and the two sets of rollers to collectively form a semi-enclosed electroplating space, ensuring that the surface of the electroplating solution reaches or exceeds the pressure rollers. This ensures that the object to be electroplated is completely immersed in the electroplating solution as it passes through the rollers. The electrode assembly is located between the two pressure rollers. During the electroplating process, the electrode assembly is positioned above the object to be electroplated and acts as the anode, while the object acts as the cathode. Current is applied to the object to be electroplated, thus electroplating its upper surface. Attached Figure Description

[0039] This utility model proposes an electroplating device.

[0040] Please see Figures 1 to 2 , Figure 1 This is a cross-sectional view of an embodiment of the electroplating apparatus provided by this utility model. Figure 2 A partial structural schematic diagram of an embodiment of the electroplating apparatus provided by this utility model.

[0041] In one embodiment of this utility model, the electroplating apparatus includes:

[0042] The receiving assembly 100 has a receiving slot 101 with an opening, and the receiving slot 101 has two opposing side walls 110.

[0043] The roller assembly 200 includes a support roller 210 and a pressure roller 220. The pressure roller 220 is disposed above the support roller 210 and abuts against the support roller 210. At least one of the support roller 210 and the pressure roller 220 has a flexible outer wall, so that the object to be electroplated 10 can be movably passed between the support roller 210 and the pressure roller 220. The roller assembly 200 is provided in two sets, and the two sets of roller assemblies 200 are disposed opposite each other above the opening. Each support roller 210 is close to a side wall 110.

[0044] Electrode assembly 300 is disposed between two pressure rollers 220; and

[0045] Each sidewall 110 is provided with a liquid blocking assembly 400, and the liquid blocking assembly 400 extends toward the corresponding idler roller 210, so that the receiving assembly 100, the two liquid blocking assemblies 400 and the two sets of roller assemblies 200 together surround and form an electroplating space for receiving electroplating solution.

[0046] The electroplating apparatus of this utility model includes a receiving assembly 100, an electrode assembly 300, two sets of roller assemblies 200, and two liquid-blocking assemblies 400. The receiving assembly 100 is provided with a receiving groove 101. The two sets of roller assemblies 200 are arranged opposite each other above the opening of the receiving groove 101. Each set of roller assemblies 200 includes a support roller 210 and a pressure roller 220. The pressure roller 220 is located above the support roller 210 and abuts against the support roller 210. At least one of the support roller 210 and the pressure roller 220 has a flexible outer wall with a certain elasticity, which can adapt to the shape of the object to be electroplated 10 and produce a certain deformation, so that the object to be electroplated 10 can pass between the support roller 210 and the pressure roller 220. This allows the roller assembly 200 to transport the object to be electroplated 10 and ensures a good seal between the object to be electroplated 10 and the roller assembly 200, preventing the electroplating liquid from flowing out along the object to be electroplated 10. Two liquid-blocking components 400 are each disposed on a side wall 110 and extend toward the roller 210, so that the receiving component 100, the two liquid-blocking components 400 and the two sets of roller components 200 together form a semi-enclosed electroplating space, so that the liquid level of the electroplating solution can reach or exceed the pressure roller 220, so that the object to be electroplated 10 will be completely immersed in the electroplating solution when passing through the roller component 200. The electrode component 300 is located between the two pressure rollers 220. During the electroplating process, the electrode component 300 is above the object to be electroplated 10 and acts as the anode, and the object to be electroplated 10 acts as the cathode, so that the current acts on the object to be electroplated 10, and the upper surface of the object to be electroplated 10 is electroplated.

[0047] This solution is applicable to electroplating the upper surface of the object to be electroplated 10 in the form of sheets, strips or thin plates, such as photovoltaic cells, continuous copper strips, etc.

[0048] The liquid-blocking assembly 400 can abut against the idler roller 210, or there can be a slight gap between them. It should be noted that since the main components of the electroplating solution are consumed during the electroplating process, the electroplating solution must continuously flow in and out to maintain its concentration. As long as the inflow rate is greater than the outflow rate, the electroplating space can be filled. Therefore, the electroplating space does not need to be, and cannot be, completely sealed. The electrode assembly 300, as the anode, can take various structural forms such as plate, grid, or rod, depending on the functional requirements.

[0049] In one embodiment, the liquid blocking assembly 400 includes a liquid blocking element 410 made of a flexible material. One end of the liquid blocking element 410 is fixed to the side wall 110, and the other end of the liquid blocking element 410 abuts against the roller 210 near the side wall 110, so that the receiving assembly 100, the two liquid blocking elements 410 and the two sets of roller assemblies 200 together surround and form an electroplating space for receiving electroplating solution.

[0050] Reference Figure 1 In an embodiment of this invention, the liquid-blocking assembly 400 includes a liquid-blocking member 410 made of a flexible material. One end of the liquid-blocking member 410 is connected to the side wall 110 of the receiving groove 101, and the other end abuts against the idler roller 210 near the side wall 110. The flexible liquid-blocking member 410 can better conform to the surface shape of the idler roller 210 and reduce interference with the roller movement, allowing the roller assembly 200 to operate more smoothly and reducing the risk of mechanical wear and jamming. In addition, during the rotation of the idler roller 210, the flexible liquid-blocking member 410 contacts the idler roller 210, resulting in less noise and vibration. Specifically, the liquid-blocking member 410 can be made of flexible materials such as rubber, silicone, or polyurethane.

[0051] In one embodiment, the liquid-blocking assembly 400 further includes a fastener, by which the liquid-blocking member 410 is fixed to the end of the sidewall 110 near the opening; and / or,

[0052] The liquid-blocking component 410 has a first end and a second end. The first end is connected to the side wall 110, and the second end abuts against the roller 210. The liquid-blocking component 410 is inclined so that the distance between the second end and the bottom wall of the receiving tank 101 is greater than the distance between the first end and the bottom wall of the receiving tank 101.

[0053] Reference Figure 2 In an embodiment of this utility model, the liquid-blocking assembly 400 further includes a fixing member 420, which fixes the liquid-blocking member 410 to the end of the side wall 110 near the opening, ensuring the firmness of the connection between the liquid-blocking member 410 and the side wall 110. The fixing member 420 may be a fixing plate, a bolt, or a combination of the two.

[0054] Reference Figure 1 In this embodiment of the invention, the height of the second end of the liquid-blocking component 410 near the idler roller 210 is higher than the height of the first end of the liquid-blocking component 410 connected to the side wall 110, so that the entire liquid-blocking component 410 is inclined. This facilitates contact with the idler roller 210 while avoiding obstructive collisions or disengagement, further ensuring the smooth rotation of the idler roller 210. Specifically, in this embodiment, the end of the side wall 110 near the opening is provided with a slope. The liquid-blocking component 410 is fitted with the slope, making the liquid-blocking component 410 inclined, which improves the convenience of inclined installation of the liquid-blocking component 410.

[0055] In one embodiment, the pressure roller 220 has a flexible outer wall, and the idler roller 210 has a rigid outer wall.

[0056] In this embodiment of the invention, the pressure roller 220 located above the object to be electroplated 10 has a flexible outer wall. Through the deformation of the flexible outer wall of the pressure roller 220, the object to be electroplated 10 can pass between the idler roller 210 and the pressure roller 220, ensuring a good seal between the object to be electroplated 10 and the roller assembly 200. The idler roller 210 located below the object to be electroplated 10 has a rigid outer wall, preventing the height of the object to be electroplated 10 from fluctuating and ensuring that the object to be electroplated 10 remains at the same height during transport, facilitating docking with other equipment. The flexible outer wall of the pressure roller 220 can be made of materials such as polyurethane or rubber.

[0057] In one embodiment, the electroplating apparatus further includes a liquid inlet assembly, one end of which is located outside the electroplating space, and the other end of which extends into the interior of the electroplating space for introducing electroplating solution into the electroplating space.

[0058] In an embodiment of this utility model, the electroplating apparatus further includes a liquid inlet assembly. One end of the liquid inlet assembly is located outside the electroplating space and is used to connect to the supply source of the electroplating solution, such as an electroplating solution storage tank, a pump system, or a pipeline network. The other end of the liquid inlet assembly extends into the interior of the electroplating space and is used to introduce the electroplating solution into the electroplating space.

[0059] In one embodiment, the liquid inlet assembly includes a first liquid inlet pipe 510, one end of which is located outside the receiving tank 101, and the other end of which extends into the receiving tank 101. The first liquid inlet pipe 510 is provided with a first liquid inlet hole 511, through which the electroplating solution enters the interior of the electroplating space from the first liquid inlet pipe 510.

[0060] Reference Figure 1 In an embodiment of this utility model, the liquid inlet assembly includes a first liquid inlet pipe 510, which is located below the object to be electroplated 10. One end of the first liquid inlet pipe 510 is located outside the receiving tank 101 and is used to connect to the supply source of the electroplating solution. The other end is located inside the receiving tank 101 and is responsible for guiding the external electroplating solution into the receiving tank 101, thereby filling the electroplating space. A first liquid inlet hole 511 is provided on the first liquid inlet pipe 510. The arrangement design of the first liquid inlet hole 511 can enable the electroplating solution to be sprayed out at a specific angle or distribution pattern, which helps to achieve a more uniform liquid flow distribution.

[0061] In one embodiment, at least two first inlet holes 511 are provided at axial intervals along the first inlet pipe 510; and / or,

[0062] At least two first liquid inlet holes 511 are provided at intervals along the circumference of the first liquid inlet pipe 510.

[0063] In the embodiments of this utility model, at least two first inlet holes 511 are provided along the length direction (axial direction) of the first liquid inlet pipe 510. The electroplating solution enters the electroplating space from holes at different axial positions, which helps to better mix with the original electroplating solution in the electroplating space. On the other hand, it avoids the electroplating solution from rushing in a large amount from a single axial point, reduces local liquid flow turbulence or impact, and makes the electroplating solution in the electroplating space more stable.

[0064] Reference Figure 1 In the embodiments of this utility model, at least two first inlet holes 511 are provided on the circumferential direction of the first liquid inlet pipe 510. The circumferentially distributed holes allow the electroplating solution to enter the electroplating space from different angles, which helps to better mix with the original electroplating solution in the electroplating space. On the other hand, it avoids the electroplating solution from rushing in from only one side of the first liquid inlet pipe 510, reduces local liquid flow turbulence or impact, and makes the electroplating solution in the electroplating space more stable.

[0065] Specifically, in this embodiment, two rows of first inlet holes 511 are provided along the circumference of the first inlet pipe 510. Each row of first inlet holes 511 is provided with multiple holes spaced apart along the axial direction of the first inlet pipe 510. The axes of the two rows of first inlet holes 511 form a 90° angle, so that both rows of first inlet holes 511 spray out toward the side and below of the first inlet pipe 510, avoiding direct impact of electroplating solution on the bottom wall of the receiving tank 101 and reducing liquid flow turbulence.

[0066] In one embodiment, the liquid inlet assembly further includes a second liquid inlet pipe 520. One end of the second liquid inlet pipe 520 is located outside the electroplating space and is connected to the first liquid inlet pipe 510. The other end of the second liquid inlet pipe 520 extends above the electrode assembly 300. The second liquid inlet pipe 520 is provided with a second liquid inlet hole 521. The electroplating solution enters the interior of the electroplating space from the second liquid inlet pipe 520 through the second liquid inlet hole 521.

[0067] Reference Figure 1 In this embodiment of the invention, the liquid inlet assembly further includes a second liquid inlet pipe 520. One end of the second liquid inlet pipe 520 is located outside the electroplating space and connected to the first liquid inlet pipe 510, so that the first liquid inlet pipe 510 and the second liquid inlet pipe 520 are both connected to the supply source of the electroplating solution. The other end of the second liquid inlet pipe 520 is located above the electrode assembly 300, responsible for guiding the external electroplating solution to the top of the electrode assembly 300, thereby filling the electroplating space. A second liquid inlet hole 521 is provided on the second liquid inlet pipe 520. The arrangement design of the second liquid inlet hole 521 can enable the electroplating solution to be sprayed out at a specific angle or distribution pattern, which helps to achieve a more uniform liquid flow distribution. By introducing liquid through the first liquid inlet pipe 510 and the second liquid inlet pipe 520, the injection flow rate of the electroplating solution is increased, ensuring that the concentration of the electroplating solution meets the electroplating requirements.

[0068] In one embodiment, the inner diameter of the second inlet pipe 520 is smaller than the inner diameter of the first inlet pipe 510.

[0069] Reference Figure 1 In this embodiment of the present invention, the inner diameter of the second liquid inlet pipe 520 is smaller than the inner diameter of the first liquid inlet pipe 510, so that the first liquid inlet pipe 510 below the object to be electroplated 10 is the main liquid inlet pipe, and the second liquid inlet pipe 520 above the object to be electroplated 10 is the auxiliary liquid inlet pipe. The first liquid inlet pipe 510 has a large flow rate, so even if some liquid flow is disturbed, the impact on the electroplating effect on the upper surface of the object to be electroplated 10 is small. The second liquid inlet pipe 520 has a small flow rate, so liquid flow disturbance is avoided, and the stability of the electroplating solution above the object to be electroplated 10 is ensured.

[0070] In one embodiment, the electroplating apparatus further includes a support roller 600, which is disposed between two support rollers 210 and is used to support the object to be electroplated 10.

[0071] Reference Figure 1 In this embodiment of the invention, the electroplating apparatus further includes a support roller 600, which is located between two idler rollers 210. One or more support rollers can be provided along the traveling direction of the object to be electroplated 10. The upper apex of the support roller 600 is flush with the upper apex of the idler roller 210, thus supporting the object to be electroplated 10 and preventing the portion of the object to be electroplated 10 between the two idler rollers 210 from collapsing or deforming, which could affect the electroplating effect or even cause damage. Specifically, in this embodiment, the support roller 600 has the same structure as the idler roller 210, reducing the types of parts in the electroplating apparatus and improving the convenience of processing and manufacturing.

[0072] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
