Description

Technical Field

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

[0002] Metal electroplating is a process that uses electrolysis to deposit a layer of another metal or alloy onto a metal surface. Its purpose is to improve the appearance of materials and impart various physicochemical properties to the material surface, such as corrosion resistance, decorative properties, wear resistance, electrical conductivity, magnetic properties, and optical properties. Electroplating involves obtaining a firmly bonded metal film on the substrate surface through electrolysis in a salt solution containing the metal to be plated. Specifically, the metal to be plated is used as the cathode, and the metal to be plated or other inert conductor is used as the anode. Direct current is applied to reduce and deposit metal ions onto the substrate surface, forming a uniform and firm metal coating. However, in existing metal electroplating equipment, the electroplating solution on the surface of the workpiece cannot perfectly and uniformly fuse with the metal during the electroplating process, resulting in inconsistent coating thickness and affecting product quality. Therefore, this application proposes a metal electroplating apparatus. Utility Model Content

[0003] The purpose of this invention is to address the problem of inconsistent coating thickness in the background technology, which affects product quality, by proposing a metal electroplating device.

[0004] The technical solution of this utility model is as follows: A metal electroplating device includes an electroplating tank and an oscillation mechanism located at the top of the electroplating tank. The oscillation mechanism includes two flexible transmission sleeves fixed to the top of the electroplating tank. The top of the flexible transmission sleeves is sleeved on the inner wall of an adjusting frame. A fixing block is fixedly connected to one side of the top of the adjusting frame. A transmission frame is rotatably connected to one side of the fixing block. A drive motor is fixedly connected to one end of the transmission frame away from the fixing block.

[0005] A current transmission mechanism is provided on one side of the outer wall of the electroplating tank.

[0006] Optionally, multiple limiting support frames are fixedly connected to both sides of the outer wall of the electroplating box. A top plate is slidably connected to the top of the limiting support frame, and electric telescopic rods are fixedly connected to both ends of the bottom of the top plate. The bottom ends of the multiple electric telescopic rods are fixedly connected to one side of the electroplating box through connecting blocks.

[0007] Optionally, a cross brace is fixedly connected to one side of the outer wall of the top plate, and a plurality of connecting sleeves are fitted on the outer wall of the cross brace. A bottom conductive block is fixedly connected to the bottom end of the connecting sleeve, and a support box is fixedly connected to the outer wall of the bottom conductive block.

[0008] Optionally, a metal plate is fixedly connected to the center of the bottom end of the adjusting frame, and the metal plate is located inside the electroplating tank.

[0009] Optionally, the current transmission mechanism includes a current controller fixed to one side of the outer wall of the electroplating tank. Two anode wires are fixedly connected to the top of the current controller, and the ends of the two anode wires away from the current controller are fixedly connected to one side of the outer wall of the bottom conductive block.

[0010] Optionally, a cathode wire is fixedly connected to the bottom of the current controller, and the end of the cathode wire away from the current controller is fixedly connected to a metal plate.

[0011] Optionally, two fixed sections are fixedly connected to both sides of the outer wall of the adjustment frame and the other two sides of the outer wall of the electroplating box, and rotating sections are rotatably connected to the inner walls of the multiple fixed sections, and spring telescopic rods are fixedly connected between the multiple rotating sections.

[0012] Compared with the prior art, this application includes at least one of the following beneficial technical effects: By setting up a drive motor, the device efficiently transmits power to the adjusting frame through the transmission frame, causing it to perform regular and appropriate up-and-down oscillating motion, which drives the electroplating solution in the electroplating tank to be fully stirred, forming a complex and uniform flow field. This effectively avoids local accumulation or uneven distribution of the electroplating solution caused by factors such as gravity and surface tension, resulting in smaller deviations in the coating thickness, ensuring the uniformity of the coating thickness, and significantly enhancing the corrosion resistance and decorative properties of the coating.

[0024] Example

[0025] like Figure 1 and Figure 4 As shown, the present invention proposes a metal electroplating device, including an electroplating tank 1 and an oscillation mechanism located at the top of the electroplating tank 1. The oscillation mechanism includes two flexible transmission sleeves 14 fixed to the top of the electroplating tank 1. The top of the flexible transmission sleeves 14 is sleeved on the inner wall of an adjusting outer frame 13. A fixing block 17 is fixedly connected to one side of the top of the adjusting outer frame 13. A transmission frame 16 is rotatably connected to one side of the fixing block 17. A drive motor 15 is fixedly connected to one end of the transmission frame 16 away from the fixing block 17. By setting two flexible transmission sleeves 14 at the top of the electroplating tank 1, the flexible transmission sleeves 14 are made of soft rubber with a certain strength. Made of materials that ensure the stability of the connection between the adjusting frame 13 and the electroplating tank 1, and also act as a buffer during the oscillation process to reduce the impact of vibration on the electroplating tank 1. The adjusting frame 13 is used to install and fix other components, and can also shake under the action of the oscillation mechanism. The fixing block 17 provides a rotation support point for the transmission frame 16. The drive motor 15 serves as the power source for the oscillation mechanism, and drives the adjusting frame 13 to oscillate up and down through the transmission frame 16, causing the electroplating solution in the electroplating tank 1 to oscillate, thereby promoting the uniform distribution of the electroplating solution on the surface of the metal workpiece to be plated, and improving the quality and uniformity of the coating.

[0026] In addition, such as Figures 1 to 4As shown, multiple limiting support frames 2 are fixedly connected to both sides of the outer wall of the electroplating tank 1. A top plate 3 is slidably connected to the top of the limiting support frame 2. Electric telescopic rods 4 are fixedly connected to both ends of the bottom of the top plate 3. The bottom ends of the multiple electric telescopic rods 4 are fixedly connected to one side of the electroplating tank 1 through connecting blocks. A cross brace 5 is fixedly connected to one side of the outer wall of the top plate 3. Multiple connecting sleeves 6 are sleeved on the outer wall of the cross brace 5. A bottom conductive block 7 is fixedly connected to the bottom end of the connecting sleeve 6. A receiving box 8 is fixedly connected to the outer wall of the bottom conductive block 7. A metal plate 12 is fixedly connected to the center position of the bottom end of the adjusting frame 13. The metal plate 12 is located inside the electroplating tank 1. Two fixed sections 18 are fixedly connected to both sides of the outer wall of the adjusting frame 13 and the other two sides of the outer wall of the electroplating tank 1. Rotating sections 19 are rotatably connected to the inner walls of the multiple fixed sections 18. Spring telescopic rods 20 are fixedly connected between the multiple rotating sections 19. By setting the metal plate 12 at the center position of the bottom end of the adjusting frame 13, the metal plate 12 serves as... The cathode, together with the metal workpiece to be plated, forms the electroplating circuit. The spring telescopic rod 20 can provide a certain buffer and support force when the outer frame 13 vibrates, ensuring the smooth movement of the outer frame 13 and enhancing the stability of the entire vibration mechanism. The limiting support frame 2 limits and supports the movement of the top plate 3. The top plate 3 can slide up and down on the limiting support frame 2. By controlling the extension and retraction of the electric telescopic rod 4, the height of the top plate 3 can be adjusted to meet the electroplating requirements of metal workpieces of different sizes. The cross support frame 5 is used to install the connecting sleeve 6. The connecting sleeve 6 can slide on the cross support frame 5 to facilitate the adjustment of the position of the bottom conductive block 7 and the support box 8. The bottom conductive block 7 is fixedly connected to the bottom end of the connecting sleeve 6. The bottom conductive block 7 serves as the anode and is connected to the current transmission mechanism to provide current for the electroplating process. The support box 8 is fixedly connected to the outer wall of the bottom conductive block 7. The support box 8 is used to place the metal workpiece to be plated, ensuring the stability of the workpiece during the electroplating process.

[0027] And, as Figure 2 and Figure 4 As shown, a current transmission mechanism is provided on one side of the outer wall of the electroplating tank 1. The current transmission mechanism includes a current controller 10 fixed to one side of the outer wall of the electroplating tank 1. Two anode wires 9 are fixedly connected to the top of the current controller 10. The ends of the two anode wires 9 away from the current controller 10 are fixedly connected to the outer wall of the bottom conductive block 7. A cathode wire 11 is fixedly connected to the bottom of the current controller 10. The end of the cathode wire 11 away from the current controller 10 is fixedly connected to the metal plate 12. By setting the current controller 10, which is of model NCP1654, the magnitude and direction of the current during the electroplating process are controlled. The current is transmitted to the bottom conductive block 7 through the anode wires 9. The end of the cathode wire 11 away from the current controller 10 is fixedly connected to the metal plate 12, forming a complete electroplating current loop. By controlling the current controller 10, the strict requirements of different metals and electroplating processes on the current can be met, thereby improving the electroplating quality.

[0028] In this embodiment, based on the size of the metal workpiece to be plated, the height of the top plate 3 is adjusted using the electric telescopic rod 4 to position the holding box 8 appropriately. The metal workpiece to be plated is then placed inside the holding box 8. An appropriate amount of electroplating solution is added to the electroplating tank 1. The current controller 10 is activated, and the current magnitude and direction are set according to the electroplating process requirements. The drive motor 15 is then activated, causing the adjusting frame 13 to drive the metal plate 12 to oscillate within the electroplating tank 1, promoting uniform distribution of the electroplating solution. During the electroplating process, the displayed data of the current controller 10 and the electroplating effect are closely observed. If necessary, the current magnitude and oscillation frequency are adjusted promptly.

[0029] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
