Description

Technical Field

[0001] This utility model relates to the field of electroplating, and specifically to an electroplating device for uniform electroplating. Background Technology

[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 is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, and enhancing aesthetics.

[0003] In existing electroplating processes, a thin layer is typically deposited on the surface of the workpiece using electroplating technology to give it certain wear resistance and corrosion resistance after it leaves the factory. However, in actual use, the electroplating equipment usually places the workpiece directly in the electroplating tank and leaves it still. In this way, the electroplating solution in the electroplating tank and the workpiece are relatively static. After a long period of electroplating, the concentration of the electroplating solution in the upper and lower layers of the electroplating tank becomes inconsistent, resulting in uneven electroplating on the workpiece surface and poor electroplating effect.

[0004] The prior art 202323457598.0 discloses an electroplating device for uniform electroplating. Although the electroplating solution in the electroplating tank is stirred by a motor-driven stirring rack, only the electroplating solution at the bottom of the electroplating tank is stirred evenly, while the electroplating solution at the top is still uneven. In addition, an extra motor is required to drive the stirring rack. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electroplating device that produces uniform electroplating.

[0009] Preferably, the drive assembly includes a first drive shaft rotatably disposed at one end in the middle of the bottom surface of the drive plate and extending through the drive plate to the other end into the electroplating tank; multiple gears respectively disposed on the first drive shaft and multiple hanger drive rods located at the top end of the drive plate and meshing with each other; a drive motor disposed on the top surface of the drive plate directly above one of the gears and connected to the gear by a connecting member; a second drive shaft rotatably disposed at one end in the middle of the bottom surface of the electroplating tank and extending through the electroplating tank to the outside; a cross-shaped protrusion disposed on the end face of the first drive shaft opposite to the second drive shaft; and a cross-shaped groove disposed on the end face of the second drive shaft opposite to the first drive shaft; a drive belt is sleeved between the end of the second drive shaft located outside the electroplating tank and the ends of the two rotating rods located outside the electroplating tank; and drive belts are also sleeved between the multiple rotating rods on both sides of the bottom surface of the electroplating tank.

[0010] Preferably, the lifting assembly includes a support frame disposed in the middle of the top surface of the electroplating tank and placed along the length of the electroplating tank, an electric telescopic rod disposed in the middle of the top surface of the support frame and with its drive end penetrating through the top surface of the support frame and facing the drive plate, and an n-shaped connecting plate disposed in the middle of the top surface of the drive plate and connected to the drive end of the electric telescopic rod.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] This invention, through its stirring and conveying component, can not only stir the electroplating solution at the bottom of the electroplating tank, but also convey the stirred electroplating solution to the top, thereby making the electroplating solution at the top more uniform and improving the uniformity of electroplating on the workpiece. Furthermore, through the driving component, it can simultaneously drive the hanging frame component to rotate and drive the stirring and conveying component to stir and convey the electroplating solution, without the need for an additional motor drive.

The bottom surfaces of the water collection tanks 5 are interconnected, and the bottom stirring ends are rotatably connected to the bottom surface of the electroplating tank 1. The drive plate 3 is equipped with a drive assembly 8 for simultaneously driving the rotation of multiple sets of hanging bracket assemblies 4 and multiple sets of stirring and conveying assemblies 7. Each set of hanging bracket assemblies 4 includes a hanging bracket drive rod 41 with one end rotatably connected to the bottom of the drive plate 3 and extending from the bottom to the top of the drive plate 3, and a hanging bracket 42 disposed on the end of the hanging bracket drive rod 41 facing the electroplating tank 1. Each set of stirring and conveying assemblies 7 includes a sleeve 71 with one end penetrating and connected to the bottom surface of the water collection tank 5, a rotating rod 72 with one end penetrating the bottom surface of the electroplating tank 1 and rotatably connected to the electroplating tank 1, and the other end extending into the sleeve 71, and several stirring blades 73 disposed on the end of the rotating rod 72 located on the bottom surface of the electroplating tank 1. A spiral blade 74 is installed on a section of the rotating rod 72 inside the sleeve 71; one end of the sleeve 71 is at a distance from the bottom of the electroplating tank 1; the driving assembly 8 includes a first drive shaft 81, one end of which is rotatably installed in the middle of the bottom surface of the drive plate 3 and passes through the drive plate 3 to the fixed part, and the other end of which extends into the electroplating tank 1; multiple gears 82 respectively installed on the first drive shaft 81 and multiple hanger drive rods 41 located at the top end of the drive plate 3 and meshing with each other; a drive motor 83 installed on the top surface of the drive plate 3 directly above one of the gears 82 and connected to the drive end of the gear 82 via a connector; a second drive shaft 84, one end of which is rotatably installed in the middle of the bottom surface of the electroplating tank 1 and passes through the electroplating tank 1 to the outside; and a drive motor 84 installed directly opposite the first drive shaft 81. A cross-shaped protrusion 85 is provided on one end face of the shaft 84, and a cross-shaped groove 86 is provided on the end face of the second drive shaft 84 opposite to the first drive shaft 81. A drive belt 87 is sleeved between the end of the second drive shaft 84 located outside the electroplating tank 1 and the end of the rotating rods 72 located outside the electroplating tank 1 on both sides. A drive belt 87 is also sleeved between the multiple rotating rods 72 on both sides of the bottom surface of the electroplating tank 1. The lifting assembly 2 includes a support frame 21 located in the middle of the top surface of the electroplating tank 1 and placed along the length of the electroplating tank 1, an electric telescopic rod 22 located in the middle of the top surface of the support frame 21 and whose drive end passes through the top surface of the support frame 21 and faces the drive plate 3, and an n-shaped connecting plate 23 located in the middle of the top surface of the drive plate 3 and connected to the drive end of the electric telescopic rod 22.

[0020] In use: First, hang the electroplating fixture on the hanger 42, then start the electric telescopic rod 22. The electric telescopic rod 22 drives the drive plate 3 to move towards the electroplating tank 1. The drive plate 3 then drives the hanger 42 and the first drive shaft 81 to move towards the electroplating tank 1. When the protrusion 85 on the first drive shaft 81 is inserted into the groove 86 of the second drive shaft 84 at the bottom of the electroplating tank 1, stop the electric telescopic rod 22. At this time, the part of the fixture on the hanger 42 with the electroplated product is completely submerged in the electroplating solution. Then start the drive motor 83. The drive motor 83 drives one of the gears 82 to rotate. Since all gears 82 are meshed, all gears 82 rotate together. Then, the gear 82 drives the hanger drive rod 41 and the first drive shaft 81 to rotate. Then, the hanger drive rod 41 drives the hanger 42 to rotate, and the hanger 42 drives the fixture to rotate. The first drive shaft 81 drives the second drive shaft 84 to rotate via the protrusion 85. The second drive shaft 84 then drives the rotating rod 72 to rotate via the drive belt 87. The rotating rod 72 drives the stirring blade 73 and the spiral blade 74 to rotate. The stirring blade 73 stirs the electroplating solution at the bottom of the electroplating tank 1, and the spiral blade 74, in cooperation with the sleeve 71, carries the stirred electroplating solution at the bottom of the electroplating tank 1 to the water collection tank 5. The electroplating solution in the water collection tank 5 then falls back into the electroplating solution at the top of the electroplating tank 1 through the outlet 6, making the electroplating solution at the top of the electroplating tank 1 more uniform, thereby improving the uniformity of electroplating of the products on the upper and lower parts of the hanger. After electroplating is completed, the drive motor 83 is stopped, the electric telescopic rod 22 is reset, and the hanger is removed. It is best to hang the next batch of hangers that need to be electroplated for the next round of electroplating.
