Description

Technical Field

[0001] This application relates to the field of electroplating equipment technology, specifically to a high-frequency vibration electroplating roller for electroplating precision components. Background Technology

[0002] Currently, electroplating of smaller parts in electroplating processes is generally completed using electroplating drums. This involves placing the metal part into a drum, which is then immersed in a chemical solution, causing the metal part to tumble, and finally applying an electric current to complete the electroplating process.

[0003] Chinese patent document CN221760013U discloses an electroplating roller, specifically comprising two fixed plates, a roller, and a connector. The roller is rotatably connected between the two fixed plates, each consisting of a first fixed plate and a second fixed plate. The connector is connected to one side of the first fixed plate and has a connecting channel. One end of the connecting channel communicates with the interior of the roller, while the other end communicates with the outside. This patent utilizes a pump to draw external chemicals into the roller, enhancing chemical exchange and maintaining a good electroplating yield.

[0004] Although the exchange of chemicals has been enhanced in the aforementioned patents, when electroplating precision components, due to their small size, the components tend to stick together or even adhere to each other, requiring the roller to rotate for a long time to achieve reliable electroplating of all surfaces of all components. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application provides a high-frequency vibration electroplating roller for electroplating precision components.

[0006] This application adopts the following technical solution: a high-frequency vibration electroplating roller for precision component electroplating, including a pair of upright plates and a roller body disposed between the pair of upright plates. Each end of the roller body is provided with a driven gear. A transmission shaft driven by an electric motor is provided between the pair of upright plates and above the roller body. Two driving gears are fixed on the transmission shaft. The two driving gears mesh with the two driven gears respectively and in a one-to-one correspondence. A vibration mechanism is also provided between the pair of upright plates.

[0007] The vibration mechanism includes a support, a vibration motor, and a vibration plate. The vibration motor is fixed above the drum body by the support. The bottom of the vibration plate is in contact with the upper part of the outer wall of the drum body. The vibration motor is used to transmit vibration energy to the vibration plate.

[0008] Optionally, the support includes a crossbeam and two first shock-absorbing pads, the crossbeam being disposed between a pair of uprights, and the first shock-absorbing pads being disposed between the end of the crossbeam and the uprights.

[0009] Optionally, a connection unit is provided between the vibration motor and the vibration plate. The connection unit includes a base plate and a pair of fins. The vibration motor is placed on the base plate, and the pair of fins are located outside the drive shaft. The top of the fins is connected to the base plate, and the bottom of the fins is connected to the top of the vibration plate.

[0010] Optionally, the base plate has a notch, the top of the fin extends through the notch to the top of the base plate, and the top of the fin has a baffle, the outer diameter of which is larger than the inner diameter of the notch.

[0011] Optionally, a cylinder is provided at the bottom of the base plate, and the cylinder is connected to the base plate through a second shock-absorbing pad. The push rod of the cylinder is connected to the vibrating plate.

[0012] Optionally, the vibrating plate has several placement slots on the side facing the drum body. A spring and a guide rod are provided in the placement slot. One end of the spring is connected to the bottom of the placement slot, and the other end of the spring is connected to one end of the guide rod. The other end of the guide rod is in contact with the drum body. The guide rod is used to transmit vibration energy to the drum body.

[0013] Optionally, the end of the guide rod that contacts the drum body is hemispherical, the vibrating plate has slopes at both ends on the side facing the drum body, and the distance between the groove opening of the placement groove and the drum body is less than the maximum distance between the slope and the drum body.

[0014] Compared with the prior art, the vibration motor in this application generates vibration energy during operation. This vibration energy is transmitted to the drum body through the base plate, fins and vibration plate. The material inside the drum body can absorb this vibration energy and generate vibration, thereby separating the materials that are in contact with each other. This ensures that the materials can fully contact the solution and improves the electroplating effect on the materials. Attached Figure Description

[0018] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] like Figure 1-2 As shown, a high-frequency vibration electroplating roller for precision component electroplating includes a pair of upright plates 1 and a roller body 2 disposed between the pair of upright plates 1. Each end of the roller body 2 is provided with a driven gear 20. Between the pair of upright plates 1 and above the roller body 2, there is a transmission shaft 12 driven by a motor 11. Two driving gears 13 are fixed on the transmission shaft 12. The two driving gears 13 mesh with the two driven gears 20 respectively and in a one-to-one correspondence. A vibration mechanism 3 is also provided between the pair of upright plates 1. The vibration mechanism 3 includes a bracket 31, a vibration motor 32 and a vibration plate 33. The vibration motor 32 is fixed above the roller body 2 by the bracket 31. The bottom of the vibration plate 33 contacts the upper part of the outer wall of the roller body 2. The vibration motor 32 is used to transmit vibration energy to the vibration plate 33.

[0020] The electric motor 11 drives the transmission shaft 12 to rotate, which in turn drives the drive gear 13 to rotate. The driven gear 20 meshes with the drive gear 13 and is located at the end of the drum body 2. Under the driving action of the drive gear 13, the driven gear 20 and the drum body 2 can rotate reliably, thereby realizing the tumbling of materials within the drum body 2. Furthermore, the vibration energy generated by the vibrating motor 32 during operation can be transmitted to the drum body 2 through the vibrating plate 33. In this way, the materials in contact with the drum body 2 can reliably vibrate, thereby allowing the materials in contact with it to separate from each other, thus effectively improving the electroplating effect.

[0021] The support 31 includes a crossbeam 311 and two first damping pads 312. The crossbeam 311 is located between a pair of vertical plates 1, and the first damping pads 312 are located between the end of the crossbeam 311 and the vertical plates 1. By setting the first damping pads 312, the vibration energy transmitted to the vertical plates 1 through the crossbeam 311 is reduced, thereby improving the efficiency of vibration energy transmission to the drum body 2 and ensuring that the material in contact with the inner wall of the drum body 2 can receive vibration energy and generate vibration.

[0022] A connecting unit is provided between the vibratory motor 32 and the vibratory plate 33. The connecting unit includes a base plate 34 and a pair of fins 35. The vibratory motor 32 is placed on the base plate 34, and the pair of fins 35 are located outside the drive shaft 12. The top of the fins 35 is connected to the base plate 34, and the bottom of the fins 35 is connected to the top of the vibratory plate 33. By setting the base plate 34 and the fins 35, the vibratory motor 32 can be reliably operated. At the same time, the fins 35 connect the base plate 34 and the vibratory plate 33, ensuring that the vibratory plate 33 is reliably connected and that the vibration energy generated by the vibratory motor 32 can be reliably transmitted to the drum body 2.

[0023] The base plate 34 has a notch 341, and the top of the fin 35 extends above the base plate 34 through the notch 341. The top of the fin 35 has a baffle 350, and the outer diameter of the baffle 350 is larger than the inner diameter of the notch 341. In other words, the fin and the base plate 34 are movably connected. Under the action of gravity, when the baffle 350 contacts the base plate 34, the vibrating plate 33 is in a fixed position.

[0024] A cylinder 36 is provided at the bottom of the base plate 34. The cylinder 36 is connected to the base plate 34 via a second damping pad 342. The push rod of the cylinder 36 is connected to the vibrating plate 33. When the cylinder is transmitting vibration energy to the drum body 2, the cylinder 36 pushes the vibrating plate 33 downward until the baffle 350 contacts the base plate 34. When it is no longer necessary to transmit vibration energy to the drum body 2, the push rod of the cylinder 36 retracts, causing the vibrating plate 33 to move away from the drum body 2. Furthermore, the second damping pad 342 is provided between the base plate 34 and the cylinder 36, which can reduce the interference of vibration energy on the cylinder 36 and improve the efficiency of transmitting vibration energy to the drum body 2.

[0025] The vibrating plate 33 has several placement grooves 331 on the side facing the drum body 2. Springs 332 and guide rods 333 are provided in the placement grooves 331. One end of the spring 332 is connected to the bottom of the placement groove 331, and the other end of the spring 332 is connected to one end of the guide rod 333. The other end of the guide rod 333 is in contact with the drum body 2. The guide rod 333 is used to transmit vibration energy to the drum body 2. The drum body 2 can be cylindrical or prismatic. When the drum body 2 is prismatic, the distance between the drum body 2 and the vibrating plate 33 will change. Specifically, during the rotation of the drum body 2, the distance between the edge of the drum body 2 and the vibrating plate 33 is the smallest. At this time, the edge of the drum body 2 will push the guide rod 333 to the inside of the placement groove 331, ensuring that the drum body 2 can rotate reliably. That is to say, under the action of the spring force of the spring 332, the guide rod 333 can reliably fit against the outer wall of the drum body 2, thereby improving the transmission effect of vibration energy and ensuring that the material in the drum body 2 can fully contact the solution, thereby improving the electroplating effect.

[0026] The end of the guide rod 333 that contacts the drum body 2 is hemispherical. The vibrating plate 33 has slopes 334 at both ends on the side facing the drum body 2. The distance between the groove opening of the placement groove 331 and the drum body 2 is less than the maximum distance between the slope 334 and the drum body 2. The hemispherical shape of the guide rod 333 and the slope 334 ensure that the drum body 2 can fully contact the guide rod 333 and absorb vibration energy while rotating.

[0027] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
