Description

Technical Field

[0001] This invention belongs to the field of metal electroplating technology, and in particular relates to a metal sealing electroplating system with airbag adjustment. Background Technology

[0002] Electroplating is a surface treatment technology based on electrochemical principles. In this process, the workpiece to be plated is used as the cathode and immersed in an electroplating solution containing metal ions for plating. At the same time, a suitable anode (soluble or insoluble) is used. After a DC power supply is turned on, the metal ions in the electroplating solution move towards the cathode under the action of the electric field and gain electrons on the surface of the workpiece, which are reduced to metal atoms and gradually deposited to form a uniform and dense metal coating. This process can improve the corrosion resistance of materials and is widely used in many industries such as automobiles, electronics, and jewelry.

[0003] However, electroplating racks usually have a fixed structure, making it difficult to flexibly adjust the hanging position according to workpieces of different sizes and shapes. This results in some workpieces with special shapes or sizes not being able to be in the optimal position during electroplating. Furthermore, the racks may not be suitable for workpieces with different hole diameters or hole spacings. When processing electroplating workpieces with holes, there is a partial contact surface between the rack surface and the workpiece hole wall, making it difficult for the electroplating solution to flow fully into the hole. This can easily lead to uneven electroplating on the hole wall or even some areas not being plated. Summary of the Invention

[0004] The purpose of this invention is to provide a metal-sealed electroplating system with airbag adjustment to solve the above-mentioned technical problems.

[0005] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A metal sealing electroplating system with airbag adjustment, the production line includes a plating tank: a lifting hanger exchange trolley is installed above the plating tank, and a hanger is provided below the lifting hanger exchange trolley. Multiple support rings are welded to the inner cavity of the hanger, and multiple hanging components are circumferentially distributed on the surface of the support rings. Each hanging component includes an adjusting seat fixedly connected to the surface of the support rings. Two adjusting sliders are slidably connected to the inner cavity of the adjusting seat. An upper hanging rod and a lower hanging rod are fixedly connected to the surfaces of the two adjusting sliders respectively. An arc-shaped through hole is opened at the bottom of the inner cavity of both the upper and lower hanging rods. A PTFE airbag is fixedly connected to the inner cavity of the arc-shaped through hole. A first air supply pipe and a second air supply pipe are fixedly connected to both sides of the adjusting seat respectively. The first air supply pipe... Both the first and second air supply pipes are fixedly connected to each other with connecting hoses. The first and second air supply pipes are fixedly connected to the upper and lower hanging rods respectively through connecting hoses and remain in communication. The traction end of the lifting-type hanger exchange vehicle is fixedly installed with multiple hangers. An air supply assembly is provided below the hangers. The air supply assembly includes a first air supply plate and a second air supply plate. Multiple upper connecting pipes are distributed in a ring on the surface of the first air supply plate and are connected to it. The bottom end of the upper connecting pipe is fixedly connected to the first air supply pipe and remains in communication. Multiple lower connecting pipes are distributed in a ring on the surface of the second air supply plate and are connected to the second air supply pipe. The inner cavity of the hanger is provided with two air supply pipe heads. The top of the hanger is provided with a docking assembly.

[0006] Preferably, the docking assembly includes a support arm welded to the top of the hanger, with hanging plates welded to both sides of the top of the support arm, and hanging holes welded to both sides of the hanger, the hanging plates being fastened into the inner cavity of the hanging holes.

[0007] Preferably, the inner cavity of the hanger is slidably connected to a sliding seat, the sliding seat is fixedly connected to the surface of two air supply pipe heads, the top of the support arm is fixedly connected to a docking seat, and both sides of the top of the docking seat are fixedly connected to air inlet pipe heads.

[0008] Preferably, the two air inlet heads are fixedly connected to the first air supply plate and the second air supply plate respectively and remain in communication. The surface of the air inlet head is fitted with a sealing gasket, and the top of the air inlet head is inserted into the inner cavity of the air supply head.

[0009] Preferably, the front and rear sides of the sliding seat are fixedly connected with hanging ears, and the front and rear sides of the docking seat are fixedly connected with latches, which are engaged in the inner cavity of the hanging ears.

[0010] Preferably, a sliding pin is fixedly connected to the top of the sliding seat, and the sliding pin is slidably connected to the inner cavity of the hanger.

[0011] Preferably, a stainless steel spring is fitted onto the surface of the sliding pin, and the top and bottom ends of the stainless steel spring are in close contact with the sliding pin and the hanger, respectively.

[0012] Preferably, a rotatable bidirectional lead screw is provided through the top of the adjusting seat, and the adjusting slider is threadedly connected to the surface of the bidirectional lead screw.

[0013] Preferably, both the upper and lower hanging rods are threaded with hexagonal nuts, which are tightly pressed against the surface of the adjusting slider.

[0014] The electroplating method for the airbag-adjustable metal-sealed electroplating system is as follows: Step 1: The user first adjusts the distance between the upper and lower hanging rods according to the size of the electroplating workpiece. During adjustment, the user drives the bidirectional lead screw to rotate. As the bidirectional lead screw rotates, it pushes the two adjusting sliders through its surface threads, allowing the two adjusting sliders to move towards or away from each other. After adjustment, the workpiece to be electroplated is hung on the surface of the upper and lower hanging rods (for double-hole workpieces, the two holes are respectively fitted onto the surface of the upper and lower hanging rods; for single-hole workpieces, they should be hung on the surface of the upper hanging rod, ensuring that the bottom of the single-hole workpiece is at the top of the lower hanging rod). Then, the user moves the hanger directly under the lifting hanger exchange vehicle, and the hanging plate is fastened into the inner cavity of the hanging hole to hang the hanger. Step 2: After the hanger is installed, the user hangs the top of the buckle in the inner cavity of the hanging ear, and then flips the buckle downward. During the downward flipping and locking process, the buckle pulls the hanging ear, causing the sliding seat to slide downward. At the same time, the sliding seat drives the sliding pin to slide downward. During the downward movement of the sliding pin, the stainless steel spring is compressed. During the downward movement of the sliding seat, the two air supply pipe heads are simultaneously sleeved on the surface of the air receiving pipe head, so that the air supply pipe head and the air receiving pipe head can be connected and sealed. Then, the user moves the hanger to the designated plating tank for electroplating treatment using a lifting hanger exchange vehicle. Step 3: During the electroplating process, gas is supplied into the inner cavity of the gas inlet pipe head through the gas supply pipe head. The gas enters the inner cavities of the first and second gas supply plates, and then is delivered to the inner cavities of the first and second gas supply pipes respectively through the first gas supply pipe and the lower connecting pipe. When electroplating a double-hole workpiece, the first gas supply pipe delivers gas to the inner cavity of the upper hanging rod. The gas reaches the arc-shaped through hole and inflates the PTFE air bladder, causing the PTFE air bladder to expand and compress the upper hole wall. At this time, the workpiece rises as a whole, and the top of the lower hole wall detaches from contact with the surface of the lower hanging rod, ensuring the entry of the electroplating solution. Subsequently, the gas is discharged from the inner cavity of the upper hanging rod, and the PTFE air bladder contracts. Upon resetting, gas is introduced into the inner cavity of the lower hanging rod, causing the PTFE air bladders on the surface of the lower hanging rod to inflate and expand. This compresses the lower hole wall of the workpiece, causing the upper hole wall of the workpiece to detach from the surface of the upper hanging rod, ensuring easy entry for electroplating. When electroplating a single-hole workpiece, gas is introduced into the inner cavity of the lower hanging rod, causing the PTFE air bladders on the surface of the lower hanging rod to inflate and expand, pushing the bottom of the workpiece forward. This causes the upper hole wall of the workpiece to detach from the upper hanging rod, ensuring the entry of the electroplating solution for electroplating. By varying the inflation and deflation of the PTFE air bladders at different positions, the contact surface between the workpiece and the upper or lower hanging rod is changed, thereby allowing the electroplating solution to enter the hole and electroplat the hole wall.

[0015] The beneficial effects of this invention are: This invention involves hanging the workpiece on the surfaces of the upper and lower hanging rods, using a hanger and docking assembly to connect the air passages, and then moving the workpiece to the designated electroplating area using a lifting fixture exchange cart and the fixtures. Subsequently, the workpiece is pneumatically lifted by the hanging assembly and the air supply assembly to ensure that the electroplating solution enters the workpiece's through-holes, thus achieving the purpose of adjusting the workpiece's electroplating position and ensuring comprehensive coverage of the electroplating solution.

[0021] Example 1: Figure 1-12 This invention illustrates an embodiment of an airbag-adjustable metal-sealed electroplating system. The production line includes a plating tank 1. A lifting fixture exchange cart 2 is mounted above the plating tank 1, and a fixture 3 is disposed below the lifting fixture exchange cart 2. Multiple support rings 4 are welded to the inner cavity of the fixture 3. Multiple hanging components 5 are circumferentially distributed on the surface of the support rings 4. Each hanging component 5 includes an adjusting seat 51 fixedly connected to the surface of the support rings 4. Two adjusting sliders 52 are slidably connected to the inner cavity of the adjusting seat 51. A rotatable bidirectional lead screw 11 is passed through the top of the adjusting seat 51. The slider 52 is threadedly connected to the surface of the double-acting lead screw 11. The double-acting lead screw 11 acts as a threaded actuator for the two adjusting sliders 52, thereby adjusting the distance between the upper hanging rod 53 and the lower hanging rod 54. This allows for easy adaptation to workpieces of different sizes. The upper hanging rod 53 and the lower hanging rod 54 are respectively fixedly connected to the surfaces of the two adjusting sliders 52. Hexagonal nuts 12 are threadedly connected to the surfaces of both the upper hanging rod 53 and the lower hanging rod 54, tightly pressing against the surfaces of the adjusting sliders 52. The bottom of the inner cavity of the upper hanging rod 53 and the lower hanging rod 54... Each part is provided with an arc-shaped through hole 55, and a PTFE air bag 56 is fixedly connected to the inner cavity of the arc-shaped through hole 55. A first air supply pipe 57 and a second air supply pipe 58 are fixedly connected to both sides of the adjusting seat 51, respectively. A connecting hose 59 is fixedly connected to the surface of the first air supply pipe 57 and the second air supply pipe 58, and the first air supply pipe 57 and the second air supply pipe 58 are fixedly connected to the upper hanging rod 53 and the lower hanging rod 54 respectively through the connecting hose 59 and keep them in a connected state. Multiple hangers 6 are fixedly installed at the traction end of the lifting-type hanger exchange vehicle 2. A gas supply assembly 7 is provided below, which includes a first gas supply plate 71 and a second gas supply plate 72. The surface of the first gas supply plate 71 is circumferentially distributed with multiple upper connecting pipes 73 connected to it. The bottom end of the upper connecting pipe 73 is fixedly connected to the first gas supply pipe 57 and remains in communication. The surface of the second gas supply plate 72 is circumferentially distributed with multiple connected lower connecting pipes 74. The bottom end of the lower connecting pipe 74 is fixedly connected to the second gas supply pipe 58 and remains in communication. The inner cavity of the hanger 6 is provided with two gas supply pipe heads 75, and the top of the hanger 3 is provided with a docking assembly 8.

[0022] Example 2: Basically the same as Example 1, but with a further improvement: The docking assembly 8 includes a support arm 81 welded to the top of the hanger 3. Hanging plates 82 are welded to both sides of the top of the support arm 81. Hanging holes 83 are welded to both sides of the hanger 6. The hanging plates 82 are fastened into the inner cavity of the hanging holes 83. A sliding seat 84 is slidably connected to the inner cavity of the hanger 6. A sliding pin 9 is fixedly connected to the top of the sliding seat 84. The sliding pin 9 is slidably connected to the inner cavity of the hanger 6. A stainless steel spring 10 is sleeved on the surface of the sliding pin 9. The top and bottom ends of the stainless steel spring 10 are in close contact with the sliding pin 9 and the hanger 6, respectively. Through the cooperation of the docking assembly 8 and the sliding pin 9, the sliding seat 84 is limited and guided, while ensuring that the air supply pipe head 75 elastically returns to its original position when not docked, preventing obstruction when the hanging plates 82 and hanging holes 83 are fastened. The sliding seat 84 is fixedly connected to the surfaces of the two air supply pipe heads 75. A docking seat 85 is fixedly connected to the top of the support arm 81. Both sides of the top are fixedly connected to air inlet heads 86. The two air inlet heads 86 are fixedly connected to the first air supply plate 71 and the second air supply plate 72 respectively and are kept in a continuous state. The surface of the air inlet head 86 is fitted with a sealing gasket. The top of the air inlet head 86 is inserted into the inner cavity of the air supply head 75. The front and rear sides of the sliding seat 84 are fixedly connected to the lugs 87. The front and rear sides of the mating seat 85 are fixedly connected to the latches 88, which are engaged in the inner cavity of the lugs 87. Through the setting of the docking component 8, the cooperation of the hanging plate 82 and the hanging hole 83 plays the role of hanging the support arm 81 and the hanger 3. At the same time, with the cooperation of the sliding seat 84 and the docking seat 85, the air inlet head 86 and the air supply head 75 are connected and ventilated. Finally, with the cooperation of the hanging ear 87 and the locking buckle 88, the sliding seat 84 and the docking seat 85 are connected and locked, ensuring the docking stability of the air supply head 75 and the air inlet head 86. The electroplating method for the airbag-adjustable metal-sealed electroplating system is as follows: Step 1: The user first adjusts the distance between the upper hanging rod 53 and the lower hanging rod 54 according to the size of the electroplated workpiece. During the adjustment, the user drives the bidirectional lead screw 11 to rotate. During the rotation, the bidirectional lead screw 11 pushes the two adjusting sliders 52 through its surface threads, so that the two adjusting sliders 52 can move towards each other or away from each other. After the adjustment is completed, the workpiece to be electroplated is hung on the surface of the upper hanging rod 53 and the lower hanging rod 54. For double-hole workpieces, the two holes are respectively fitted onto the surface of the upper hanging rod 53 and the lower hanging rod 54. For single-hole workpieces, they need to be hung on the surface of the upper hanging rod 53, and the bottom of the single-hole workpiece is ensured to be located at the top of the lower hanging rod 54. Then the user moves the hanger 3 to directly below the lifting hanger exchange vehicle 2, and makes the hanging plate 82 snap into the inner cavity of the hanging hole 83, and hangs the hanger 3. Step 2: After the hanger 3 is installed, the user hangs the top of the buckle 88 in the inner cavity of the hanging ear 87, and then flips the buckle 88 downward. During the downward flipping and locking process, the buckle 88 pulls the hanging ear 87, causing the sliding seat 84 to slide downward. At the same time, the sliding seat 84 drives the sliding pin 9 to slide downward. During the downward movement, the sliding pin 9 compresses the stainless steel spring 10. During the downward movement, the sliding seat 84 drives the two air supply pipe heads 75 to be simultaneously fitted onto the surface of the air receiving pipe head 86, so that the air supply pipe head 75 and the air receiving pipe head 86 can be connected and sealed. Then, the user moves the hanger 3 to the designated plating tank 1 for electroplating treatment using the lifting hanger exchange vehicle 2. Step 3: During the electroplating process, gas is supplied into the inner cavity of the gas inlet pipe 86 through the gas supply pipe head 75. The gas enters the inner cavities of the first gas supply plate 71 and the second gas supply plate 72, and then is delivered to the inner cavities of the first gas supply pipe 57 and the second gas supply pipe 58 through the first gas supply pipe 57 and the lower connecting pipe 74, respectively. When electroplating a double-hole workpiece, the first gas supply pipe 57 delivers gas to the inner cavity of the upper hanging rod 53. The gas reaches the arc-shaped through hole 55 and inflates the PTFE air bladder 56, causing the PTFE air bladder 56 to expand and bulge, compressing the upper hole wall. At this time, the workpiece rises as a whole, and the top of the lower hole wall detaches from contact with the surface of the lower hanging rod 54, ensuring the entry of the electroplating solution. Subsequently, the gas is discharged from the inner cavity of the upper hanging rod 53, the PTFE air bladder 56 contracts and resets, and gas is introduced into the inner cavity of the lower hanging rod 54, so that the workpiece located at the upper hanging rod 53... The PTFE air bladder 56 on the surface of the lower hanging rod 54 inflates, compressing the lower hole wall of the workpiece and causing the upper hole wall of the workpiece to detach from contact with the surface of the upper hanging rod 53, ensuring easy entry for electroplating. When electroplating a single-hole workpiece, inflation into the inner cavity of the lower hanging rod 54 causes the PTFE air bladder 56 on the surface of the lower hanging rod 54 to inflate, pushing the bottom of the workpiece forward and causing the upper hole wall of the workpiece to detach from contact with the upper hanging rod 53, ensuring the electroplating solution can enter and achieve electroplating. By varying the inflation and deflation of the PTFE air bladder 56 at different positions, the contact surface between the workpiece and the upper or lower hanging rod 53 is changed, allowing the electroplating solution to enter the hole and electroplat the hole wall. After plating, the workpiece is analyzed using a spectrometer, and the average plating thickness is measured to be 2.29559 μm. Imaging images and spectral analysis diagrams are generated. The workpiece under test is a power divider under the category of radio frequency devices. The test time is 40 seconds, and the spectrometer used is model EDX1800B.

[0023] In summary, this airbag-adjustable metal sealing electroplating system achieves airway connection by hanging the workpiece on the surfaces of the upper hanging rod 53 and lower hanging rod 54, and through the cooperation of the hanger 6 and docking assembly 8. The workpiece is then moved to the designated electroplating area through the cooperation of the lifting fixture exchange cart 2 and the fixture 3. Subsequently, the workpiece position is pneumatically lifted by the cooperation of the hanging assembly 5 and the air supply assembly 7, ensuring that the electroplating solution enters the workpiece's through-hole. This achieves the purpose of adjusting the workpiece's electroplating position and ensuring comprehensive coverage of the electroplating solution.

[0024] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the invention to achieve the purpose of the invention.
