[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It utilizes electrolysis to coat the surface of metal or other material parts with a metallic film, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhancing aesthetics. It has important applications in most modern metal-related industrial production.

[0051] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection via an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0052] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0053] The terms "first," "second," and "third" (if applicable) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0054] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Figure 1 This is a schematic diagram of the structure of a conductive device in related technologies. Figure 2 for Figure 1 A cross-sectional view along section AA.

[0057] See Figure 1 and Figure 2 As shown, in the related technology, the conductive device is provided with a mechanical spring assembly 10. The relative positions of the collector ring 230 and the collector brush 210 can be adjusted by the mechanical spring assembly 10, so that the collector brush 210 and the collector ring 230 are kept in contact. In use, the position of the collector brush 210 can be adjusted by rotating the nut above the spring 11 in the mechanical spring assembly 10, and a preload can be applied to the collector brush 210 and the collector ring 230.

[0058] However, there are four mechanical spring assemblies 10. When the four mechanical spring assemblies 10 are adjusted, the consistency is poor. That is to say, the compression of the four springs 11 is inconsistent. As a result, the uniformity of force on the collector brush 210 and the collector ring 230 is poor, which can easily affect the current transmission effect of the conductive device.

[0059] Moreover, when the collector brush 210 wears, the interaction force between the collector brush 210 and the collector ring 230 will change. Adjusting the compression of the spring by adjusting the nut will adjust the interaction force between the collector brush 210 and the collector ring 230, but this adjustment method is quite difficult.

[0060] To solve the above-mentioned technical problems, the present invention provides a conductive device and an electroplating equipment. The conductive device is provided with an adjustment component, which includes a control module and at least two driving components. The control module can control the output pressure of the driving components to be constant, so that the current collector brush and the current collector ring are subjected to uniform and constant force.

[0061] Figure 3 This is a schematic diagram of the structure of the conductive device provided in an embodiment of the present invention. Figure 4 for Figure 3 A sectional view along section BB. Figure 5 This is a schematic diagram showing the positions of the conductive components and driving elements in the conductive device provided in an embodiment of the present invention.

[0062] See Figures 3 to 5As shown, the present invention provides a conductive device, including a fixing base 100, a conductive component 200, and an adjusting component 300.

[0063] The conductive component 200 includes a collector brush 210, a water-cooling tank 220, and a collector ring 230. The collector brush 210 is disposed in the water-cooling tank 220, and the collector ring 230 is partially located in the water-cooling tank 220 and abuts against the collector brush 210.

[0064] The regulating component 300 includes a control module 310 and at least two drive members 320, which are located on opposite sides of the conductive component 200. One end of the drive member 320 is connected to the fixed base 100 and the other end is connected to the water cooling tank 220. The control module 310 is connected to the drive member 320 and is configured to control the output pressure of the drive member 320.

[0065] The collector ring 230 is sleeved on the cathode roller 1100, and the cathode roller 1100 drives the collector ring 230 to rotate relative to the collector brush 210.

[0066] Specifically, the conductive component 200 also includes a conductive busbar 240 through which a large current is transferred to a water-cooling tank 220, which contains conductive oil. The current is then transferred to the collector ring 230 through the conductive oil and the collector brush 210.

[0067] Among them, the fixing seat 100 is an insulating fixing seat.

[0068] For example, the drive unit 320 can be a pneumatic drive unit or a hydraulic drive unit. This embodiment does not impose a specific limitation.

[0069] In use, the control module 310 controls each drive component 320 to output a constant pressure, and the sum of the pressures output by each drive component 320 is equal to the sum of the gravity driven by the drive component 320 and the preload of the collector brush 210 and the collector ring 230.

[0070] The gravity driven by the drive component 320 includes the gravity of the water cooling tank 220, the conductive oil, and the collector brush 210.

[0071] It is understandable that controlling the output pressure of each driving component 320 through the control module 310 can ensure that the collector brush 210 and the collector ring 230 are subjected to uniform force. This improves the stability and reliability of current transmission in the conductive device. Furthermore, it extends the service life of the collector brush 210.

[0072] When the collector brush 210 wears, the force between the collector brush 210 and the collector ring 230 tends to decrease. The drive component 320 drives the water cooling tank 220 and the collector brush 210 to move toward the collector ring 230, thereby keeping the force between the collector brush 210 and the collector ring 230 constant.

[0073] By inputting the target pressure into the control module 310, the pressure output by the drive unit 320 can be controlled, making adjustment convenient.

[0074] The number of drive components 320 can be two, four, or six; this embodiment does not impose a specific limitation.

[0075] The conductive device provided in this embodiment comprises a fixed base 100, a conductive component 200, and an adjusting component 300. The conductive component 200 includes a collector brush 210, a water-cooling tank 220, and a collector ring 230. The collector brush 210 is disposed within the water-cooling tank 220, and the collector ring 230 is partially located within the water-cooling tank 220 and abuts against the collector brush 210. The adjusting component 300 includes a control module 310 and at least two driving members 320. The at least two driving members 320 are located on opposite sides of the conductive component 200. One end of each driving member 320 is connected to the fixed base 100, and the other end is connected to the water-cooling tank 220. The control module 310 is connected to the driving members 320 and is configured to control the output pressure of the driving members 320. In this way, the collector brush 210 and the collector ring 230 are subjected to uniform force, and the interaction force between the collector brush 210 and the collector ring 230 remains constant, thereby ensuring the current transmission effect of the conductive device.

[0076] In one possible implementation, the control module 310 includes a controller 311 and a pressure reducing valve 312, with the controller 311 electrically connected to the pressure reducing valve 312 and the pressure reducing valve 312 connected to the drive unit 320.

[0077] Specifically, the pressure reducing valve 312 is connected to the drive unit 320 via a pipeline.

[0078] Among them, the controller 311 can be a PLC (Programmable Logic Controller).

[0079] Among them, pressure reducing valve 312 is an adjustable pressure reducing valve.

[0080] In use, the controller 311 can control the outlet pressure of the pressure reducing valve 312 according to process requirements, thereby controlling the output pressure of the drive unit 320.

[0081] In some embodiments, the adjustment component 300 includes at least two first connectors 330 and at least two second connectors 340, with the at least two first connectors 330 and at least two second connectors 340 being configured in a one-to-one correspondence. The first connectors 330 and the second connectors 340 are connected, and a drive component 320 is connected to the water cooling tank 220 through one first connector 330 and one second connector 340.

[0082] Specifically, the extension direction of the first connector 330 is perpendicular to the extension direction of the second connector 340.

[0083] The driving component 320 drives the water cooling tank 220 to move toward the collector ring 230 via the first connector 330 and the second connector 340, thereby bringing the collector brush 210 closer to the collector ring 230.

[0084] It is understandable that by setting the first connector 330 and the second connector 340, the layout of the component 300 and the conductive component 200 can be adjusted, which is beneficial to the compact structure of the conductive device.

[0085] The side of the first connector 330 facing away from the drive member 320 is on the same horizontal plane as the axis of the slip ring 230.

[0086] In one possible implementation, there are two drive members 320, which are located on opposite sides of the slip ring 230 and are symmetrically arranged about the axis of the slip ring 230.

[0087] In this way, while ensuring that the collector ring 230 and collector brush 210 are subjected to uniform force, the number of driving components 320 is reduced, which helps to reduce the footprint of the conductive device and lower the cost of the conductive device.

[0088] In some embodiments, the conductive device further includes a scale member 400 and an indicator member 500, one of which is connected to the base 100 and the other is connected to the second connector 340.

[0089] It should be noted that, for ease of explanation, the following description will use the scale element 400 being mounted on the second connector 340 and the indicator element 500 being mounted on the fixed base 100.

[0090] See Figure 3 and Figure 4 As shown, the scale element 400 can be a scale ruler, and the indicator element 500 can be an indicator arrow. One end of the indicator element 500 is adjacent to the scale on the scale element 400.

[0091] Understandably, when the collector brush 210 wears down, the drive component 320 drives the first connector 330, the second connector 340, the water-cooling tank 220, and the collector brush 210 to move simultaneously toward the collector ring 230, thereby compensating for wear. When the collector brush 210 is severely worn, it needs to be replaced promptly.

[0092] Therefore, by setting the scale component 400 and the indicator component 500, the distance that the second connector 340 moves toward the collector ring 230 can be intuitively represented. When the indicator component 500 indicates a certain scale of the scale component 400, it indicates that the collector brush 210 is severely worn and needs to be replaced in time, which makes it easier to judge the wear condition of the collector brush 210.

[0093] For example, in the initial state, the indicator 500 indicates a scale of 1. When the indicator indicates a scale of 5, it indicates that the collector brush 210 is severely worn and needs to be replaced in time.

[0094] In some embodiments, a scale may be provided on the second connector 340, so that the second connector 340 can serve as a scale member 400, simplifying the structure and facilitating processing.

[0095] In one possible implementation, the conductive device further includes a displacement sensor 600, which is electrically connected to the controller 311 and is used to detect the displacement of the second connector 340 relative to the fixed base 100.

[0096] For example, the displacement sensor 600 can be an inductive displacement sensor or a resistive displacement sensor. This embodiment does not specifically limit the type of displacement sensor.

[0097] By setting up a displacement sensor 600, the displacement sensor 600 transmits real-time data to the controller 311. The controller 311 can determine abnormal movement of the conductive device and issue a timely notification, which facilitates user processing and optimization.

[0098] For example, if abnormal vibration occurs during the movement of the slip ring 230, the second connector 340 will vibrate in the vertical direction, which can improve the reliability of the conductive device.

[0099] In this embodiment, the conductive device also includes a gas source 700, which is connected to the driving component 320.

[0100] Understandably, by setting the gas source to 700, the conductive device does not require an external gas source, thus increasing the flexibility of its application.

[0101] It should be noted that the drive unit 320 uses a pneumatic method, which is more in line with environmental protection requirements, produces no pollution, and is easy to obtain compressed air, resulting in lower costs.

[0102] In one possible implementation, the conductive device further includes a gas source triplet 800, which is connected to the drive unit 320 and is located between the gas source and the pressure reducing valve 312.

[0103] The air supply triplet 800 includes an air filter 810, a first pressure reducing valve 820, and an oil mist lubricator 830.

[0104] The first pressure reducing valve 820 can stabilize the gas source, keeping it in a constant state and reducing damage to hardware such as valves or actuators caused by sudden changes in gas source pressure.

[0105] Air filter 810 is used to clean compressed air and can filter out moisture in the compressed air to prevent moisture from entering the device with the gas.

[0106] The 830 oil mist lubricator can lubricate moving parts and components that are inconvenient to lubricate, greatly extending their service life.

[0107] In some embodiments, the conductive device further includes a switching valve 900, which is disposed between the gas source and the gas source triplet 800.

[0108] Among them, the switching valve 900 is used to control the opening or closing of the gas source 700.

[0109] In one possible implementation, the drive unit 320 is an airbag lifter.

[0110] Understandably, the airbag lifter is an insulating component, which can effectively prevent circuit failures caused by the conductivity of the drive component 320.

[0111] The airbag lifter can be a commonly used airbag lifter, as long as it includes an insulating component.

[0112] The present invention also provides an electroplating device, which includes a power supply device and a conductive device provided in the first aspect, wherein the power supply device is connected to the water cooling tank 220 of the conductive device.

[0113] Specifically, the power supply unit is connected to the water cooling tank 220 via a busbar 240.

[0115] Furthermore, the conductive device in this embodiment has the same structure as the conductive device provided in any of the above embodiments, and can bring the same or similar technical effects.

In other embodiments of this application, the electroplating equipment may include more or fewer components than illustrated, or combine some components, or separate some components, or have different component arrangements. For example, the electroplating equipment may also include a material to be electroplated, and a conductive device is connected between the power supply equipment and the material to be electroplated, the conductive device being used to transmit current to the material to be electroplated.

[0117] It should be noted that the conductive device provided in the above embodiments can also be used in engineering machinery where large rotating brushes transmit current.
