Description

Technical Field

[0001] This application relates to the field of electroplating degreasing technology, and in particular to a degreasing device for electroplated workpieces. 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, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics. Before electroplating, the metal workpiece usually needs to be degreased.

[0003] A degreasing device for electroplated workpieces is proposed in the related technology, including a degreasing tank, a partition, and a support seat. The partition is located in the middle of the degreasing tank, dividing the degreasing tank into a degreasing area and a part removal area. The support seat is slidably connected to the bottom wall of the degreasing tank below the partition. In use, the workpiece is placed on the support seat. After the oil is removed, it floats in the degreasing area. Moving the support seat to the part removal area can prevent the oil floating on the surface from adhering to the workpiece when it is taken out.

[0004] Regarding the aforementioned technologies, when the workpieces are small and numerous, after being stacked on the support, the contact between each workpiece and the liquid is inconsistent, which can easily lead to inconsistent degreasing effects and affect the subsequent electroplating of the workpieces. Utility Model Content

[0005] To address the issue that when a large number of small workpieces are stacked on a support, inconsistent contact between the workpieces and the liquid can lead to inconsistent degreasing effects and negatively impact subsequent electroplating, this application provides a degreasing device for electroplated workpieces.

[0006] The degreasing device for electroplated workpieces provided in this application adopts the following technical solution:

[0007] An oil removal device for electroplated workpieces includes an outer shell, an inner shell, and an ultrasonic generator. The inner shell is coaxially disposed inside the outer shell and is rotatably connected to the outer shell around its own axis. A top plate is detachably connected to the top of the inner shell, and multiple agitator plates are provided on the top plate. A drive mechanism for driving the inner shell to rotate is provided on the outer shell. Multiple water-permeable holes are opened on the peripheral wall of the lower half of the inner shell. A movable disk is provided inside the inner shell, and the outer diameter of the movable disk matches the inner diameter of the inner shell. The movable disk is engaged with the bottom wall of the outer shell. The ultrasonic generator is disposed on the inner wall of the bottom of the outer shell. A water inlet pipe is provided on the bottom peripheral wall of the outer shell, and a water outlet pipe is provided on the middle peripheral wall of the outer shell.

[0008] By adopting the above technical solution, the water inlet pipe injects cleaning fluid into the outer cylinder, and water enters the inner cylinder through the water-permeable holes on the inner cylinder's peripheral wall. The moving plate is placed on the bottom wall of the outer cylinder and engaged. Then, the workpiece is placed on the moving plate, and the drive mechanism drives the inner cylinder to rotate around its own axis. Multiple agitator rods on the top plate of the inner cylinder rotate accordingly, agitating the electroplated workpiece placed in the inner cylinder. At the same time, the ultrasonic generator operates, and the generated ultrasonic waves act on the water and the workpiece, thereby removing the oil on the workpiece and causing it to float on the water surface. Then, the moving plate is lifted, moving the workpiece upward. When the moving plate moves to the upper part of the inner cylinder, the water level in the inner cylinder rises accordingly, and the upper layer of oil overflows the top of the inner cylinder and flows into the outer cylinder. At this point, the workpiece can be removed without oil adhering. The combined design of the drive mechanism, ultrasonic generator, moving plate, and inner cylinder structure ensures that the workpiece is thoroughly degreased, resulting in good degreasing effect. This improves the problem that when there are many small workpieces stacked on the support, the contact between each workpiece and the liquid is inconsistent, which can easily lead to inconsistent degreasing effect and affect the subsequent electroplating of the workpiece.

[0009] Optionally, the drive mechanism includes a rotary motor, a drive gear, and an external gear ring. The rotary motor is mounted on the outer casing, the drive gear is mounted on the rotating shaft of the rotary motor, and the external gear ring is coaxially connected to the inner casing. The drive gear and the external gear ring mesh.

[0010] By adopting the above technical solution, after the rotating motor starts, its rotating shaft drives the drive gear to rotate. Since the drive gear meshes with the external gear ring coaxially connected to the inner cylinder, the rotation of the drive gear will drive the external gear ring to rotate, thereby causing the inner cylinder to rotate around its own axis. The stirring rod on the inner wall of the inner cylinder also rotates accordingly, thereby agitating the liquid and workpiece in the inner cylinder and improving the degreasing effect.

[0011] Optionally, a rotating shaft is coaxially inserted on the movable disk, the rotating shaft is rotatably connected to the movable disk around its own axis, the rotating shaft is provided with helical blades, and the movable disk is provided with a rotating assembly for driving the rotating shaft to rotate.

[0012] By adopting the above technical solution, the rotating component drives the rotating shaft to rotate, which in turn drives the spiral blades to rotate, thereby driving the workpieces inside the inner cylinder to tumble up and down, thus further improving the stirring effect of the workpieces and improving the degreasing effect of each workpiece.

[0013] Optionally, the rotating assembly includes a first gear and a second gear, the first gear being coaxially connected to a rotating shaft, the second gear being rotatably connected to a movable disk, and an internal gear ring being coaxially connected to the inner cylinder, the second gear meshing with the first gear and the internal gear ring respectively.

[0014] By adopting the above technical solution, when the inner cylinder rotates, it drives the internal gear ring to rotate, which in turn drives the second gear to rotate, thereby driving the first gear to rotate, and then driving the rotating shaft to rotate. No additional power source is required, saving manufacturing costs.

[0015] Optionally, a handle is provided at the top of the rotating shaft.

[0016] By adopting the above technical solution, the handle makes it easy to lift the rotating shaft, thereby driving the moving plate to rise and fall. The structure is simple and easy to use.

[0017] Optionally, the bottom of the movable disk is provided with a snap-fit ​​block, and the bottom wall of the outer shell is provided with a snap-fit ​​groove. The snap-fit ​​block is snapped into the snap-fit ​​groove. The snap-fit ​​block is a permanent magnet, and the snap-fit ​​groove is provided with a first magnet that attracts the snap-fit ​​block.

[0018] By adopting the above technical solution, after the snap-fit ​​block is placed in the snap-fit ​​groove, the snap-fit ​​block is attracted to the first magnet, which can restrict the movement of the moving disk, making it easier for the stirring rod on the inner cylinder to stir the workpiece and improve stability.

[0019] Optionally, the snap-fit ​​block has a trapezoidal cross-section, and the width of the snap-fit ​​block at the end near the moving disk is greater than the width at the end away from the moving disk.

[0020] By adopting the above technical solution, the trapezoidal design of the snap-fit ​​block facilitates the insertion of the snap-fit ​​block into the snap-fit ​​slot from top to bottom, thereby improving snap-fit ​​efficiency.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The combined arrangement of the drive mechanism, ultrasonic generator, moving disk, and inner cylinder structure ensures that the workpiece is thoroughly degreased, resulting in a good degreasing effect. This improves the problem that when a large number of small workpieces are stacked on the support, the inconsistent contact between each workpiece and the liquid can easily lead to inconsistent degreasing effects and affect subsequent electroplating of the workpieces.

[0023] 2. The arrangement of the rotating shaft, helical blades, and rotating assembly allows the rotating assembly to drive the rotating shaft to rotate, thereby causing the helical blades to rotate. This enables the workpiece inside the inner cylinder to tumble up and down, further enhancing the mixing effect of the workpiece and improving the oil removal efficiency.

[0024] 3. The engagement of the first gear, the second gear, and the internal gear ring allows the inner cylinder to rotate, which in turn drives the internal gear ring to rotate, which in turn drives the second gear to rotate, which in turn drives the first gear to rotate, and in turn drives the rotating shaft to rotate. This eliminates the need for an additional power source and saves manufacturing costs. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses an oil removal device for electroplated workpieces. (Refer to...) Figure 1-2 The degreasing device for electroplated workpieces includes an outer shell 1, an inner cylinder 2, an ultrasonic generator 3, a drive mechanism, and a moving disc 4. The outer shell 1 is cylindrical, with an open top and a closed bottom. A water inlet pipe 11 is connected to the bottom periphery of the outer shell 1, and a water outlet pipe 12 is connected to the middle periphery of the outer shell 1. The inner cylinder 2 is coaxially mounted inside the outer shell 1 and rotatably connected to the outer shell 1 around its own axis. The inner cylinder 2 has openings at both ends and is taller than the outer shell 1. A top plate 21 is detachably connected to the top of the inner cylinder 2 by bolts, and multiple agitator rods 22 extending into the inner cylinder 2 are located at the top and bottom. The drive mechanism is mounted on the outer shell 1 and drives the inner cylinder 2 to rotate. Multiple water-permeable holes 23 are formed on the periphery of the lower half of the inner cylinder 2. The moving disc 4 is located inside the inner cylinder 2, with its outer diameter matching the inner diameter of the inner cylinder 2. The moving disc 4 is engaged with the bottom wall of the outer shell 1. The ultrasonic generator 3 is located on the inner bottom wall of the outer shell 1.

[0032] In use, cleaning fluid is injected into the outer shell cylinder 1 through the water inlet pipe 11. Water enters the inner cylinder 2 through the water permeable holes 23 on the circumferential wall of the inner cylinder 2. Water injection is stopped when the water level approaches the top of the outer shell cylinder 1. Then, the moving plate 4 is placed on the bottom wall of the outer shell cylinder 1 and secured. The workpiece is then placed on the moving plate 4 and connected to the top plate 21 by bolts. The drive mechanism then drives the inner cylinder 2 to rotate around its own axis. Multiple agitator rods 22 on the top plate 21 of the inner cylinder 2 rotate accordingly, agitating the electroplated workpiece placed in the inner cylinder 2. At the same time, the ultrasonic generator 3 operates, generating ultrasonic waves. Utilizing the cavitation effect of the ultrasonic waves, a large number of tiny bubbles are generated in the cleaning fluid. When these bubbles burst, they generate a powerful... The impact force can more effectively remove oil stains from the surface of the workpiece. The oil is removed and floats on the water surface. Then, the top plate 21 is removed, and the moving plate 4 is lifted to move the workpiece upward. When the moving plate 4 moves to the upper part of the inner cylinder 2, the water level in the inner cylinder 2 rises accordingly. The upper layer of oil overflows the top of the inner cylinder 2 and flows into the outer cylinder 1. At this time, the workpiece can be taken out without oil adhering. The joint arrangement of the drive mechanism, ultrasonic generator 3, moving plate 4 and inner cylinder 2 structure ensures that the workpiece is thoroughly degreased, and the degreasing effect is good. This improves the problem that when there are many small workpieces, after they are stacked on the support, the contact between each workpiece and the liquid is inconsistent, which can easily lead to inconsistent degreasing effect and affect the subsequent electroplating of the workpiece.

[0033] For example, the drive mechanism includes a rotary motor 13, a drive gear 14, and an external gear ring 24. The rotary motor 13 is mounted on the outer casing 1, the drive gear 14 is mounted on the rotating shaft of the rotary motor 13, and the external gear ring 24 is coaxially connected to the inner casing 2. The drive gear 14 and the external gear ring 24 mesh. After the rotary motor 13 starts, it drives the drive gear 14 to rotate. The drive gear 14 transmits power to the external gear ring 24 through meshing, thereby causing the inner casing 2 to rotate. The rotary motor 13 can be a common AC motor or DC motor, and the drive gear 14 and the external gear ring 24 can be made of metal materials, such as carbon steel or alloy steel, to ensure sufficient strength and wear resistance. In some special cases, gears made of plastic materials can also be used to reduce weight and cost.

[0034] The bottom of the movable disk 4 is provided with a locking block 41, and the bottom wall of the outer casing 1 is provided with a locking groove 15. The locking block 41 is locked in the locking groove 15. The locking block 41 is a permanent magnet, and the locking groove 15 is provided with a first magnet 16 that attracts the locking block 41. The locking block 41 and the locking groove 15 are engaged in a trapezoidal locking manner, that is, the cross-section of the locking block 41 is trapezoidal, and the width of the end of the locking block 41 near the movable disk 4 is greater than the width of the end away from the movable disk 4 to ensure smooth locking. The material of the locking block 41 can be the same as the material of the outer casing 1 and the movable disk 4 to ensure good compatibility.

[0035] To further improve the mixing efficiency of the workpiece, a rotating shaft 42 is coaxially inserted on the moving disk 4. The rotating shaft 42 is rotatably connected to the moving disk 4 around its own axis. A spiral blade 43 is provided on the rotating shaft 42, and a rotating assembly is provided on the moving disk 4 to drive the rotating shaft 42 to rotate. The combination of the rotating shaft 42 and the spiral blade 43 generates an upward water flow during rotation, promoting the circulation of the degreasing liquid and causing the workpiece to tumble up and down, ensuring full contact between the workpiece and the degreasing liquid and improving the degreasing effect. The rotating shaft 42 can be made of metal, and the spiral blade 43 can be made of plastic or metal, and is fixed to the rotating shaft 42 by welding or bolting.

[0036] Specifically, refer to Figure 2-3 The rotating assembly includes a first gear 44 and a second gear 45. The first gear 44 is coaxially connected to the rotating shaft 42, and the second gear 45 is rotatably connected to the movable disk 4. An internal gear ring 25 is coaxially connected to the inner cylinder 2. The second gear 45 meshes with both the first gear 44 and the internal gear ring 25. When the inner cylinder 2 rotates, the internal gear ring 25 rotates accordingly. Through the transmission of the second gear 45, the first gear 44 is driven to rotate, thereby causing the rotating shaft 42 to rotate. This eliminates the need for an additional power source, saving costs.

[0037] A handle 46 is provided at the top of the rotating shaft 42, which allows operators to easily remove the rotating shaft 42 and the movable disc 4 from the inner cylinder 2 for cleaning or replacement. The handle 46 can be made of plastic or metal and is fixed to the top of the rotating shaft 42 by welding or threaded connection.

[0038] The implementation principle of the degreasing device for electroplated workpieces in this embodiment is as follows: During use, cleaning fluid is injected into the outer shell cylinder 1 through the water inlet pipe 11. Water enters the inner cylinder 2 through the water permeable holes 23 on the circumferential wall of the inner cylinder 2. Water injection is stopped when the water level approaches the top of the outer shell cylinder 1. Then, the moving plate 4 is placed on the bottom wall of the outer shell cylinder 1 and secured. The workpiece is then placed on the moving plate 4 and connected to the top plate 21 by bolts. Next, the rotating motor 13 is started to drive the drive gear 14 to rotate, which in turn drives the outer gear ring 24 to rotate, thereby driving the inner cylinder 2 to rotate around its own axis. The multiple stirring rods 22 on the top plate 21 of the inner cylinder 2 rotate accordingly, stirring the electroplated workpiece placed in the inner cylinder 2. At the same time, the ultrasonic generator 3 works, generating ultrasonic waves and utilizing the cavitation effect of the ultrasonic waves to agitate the cleaning fluid. A large number of tiny bubbles are generated, and when these bubbles burst, they produce a powerful impact force, which can more effectively remove oil stains from the surface of the workpiece. The oil is removed and floats on the water surface. Then, the top plate 21 is removed, and the moving plate 4 is lifted to move the workpiece upward. When the moving plate 4 moves to the upper part of the inner cylinder 2, the water level in the inner cylinder 2 rises accordingly, and the upper layer of oil overflows the top of the inner cylinder 2 and flows into the outer cylinder 1. At this time, the workpiece can be removed without oil adhering. The joint arrangement of the drive mechanism, ultrasonic generator 3, moving plate 4 and inner cylinder 2 structure ensures that the workpiece is thoroughly degreased, and the degreasing effect is good. This improves the problem that when there are many small workpieces, after they are piled on the support, the contact between each workpiece and the liquid is inconsistent, which can easily lead to inconsistent degreasing effect and affect the subsequent electroplating of the workpiece.

[0039] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
