Description

Technical Field

[0001] This invention relates to the field of electroplating technology, and in particular to a device and method for cleaning residual copper foil from electroplating racks. Background Technology

[0002] Electroplating racks are process equipment used in electroplating production to suspend and fix parts to be plated and to connect them as cathodes to the electroplating circuit. They are usually made of copper or brass with good conductivity as the main frame and are key tooling that directly affects the quality and cost of electroplating. As the electroplating process is repeated, copper layers will continuously accumulate on the conductive contacts and in areas of local insulation damage of the rack, resulting in effective current dispersion, uneven plating of parts, and even local scorching. Therefore, cleaning residual copper foil is a key maintenance step to ensure stable electroplating quality.

[0003] Currently, the following problems still exist when cleaning residual copper foil from electroplating racks: Existing devices mostly use a suspended static or single-axis rotating method, but the complex structure of electroplating racks makes it impossible to completely remove the residual copper foil, resulting in a large number of dead corners in the cleaning process. At the same time, relying solely on chemical immersion to remove copper is insufficient for peeling off residual copper foil that is firmly bonded to the rack, resulting in a long cleaning cycle and problems such as uneven cleaning or localized over-corrosion. Summary of the Invention

[0004] In view of the problems of fixed rack posture and limited cleaning methods in the above-mentioned or existing technologies when cleaning residual copper foil from electroplating racks, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides a device and method for cleaning residual copper foil from electroplating racks, which is achieved by the following specific technical means: A device for cleaning residual copper foil from electroplating racks includes a cleaning tank, and a hoisting assembly is fixedly installed above the cleaning tank. A spherical roller cage mechanism is located below the hoisting assembly. The spherical roller cage mechanism includes a first rotating ring rotatably mounted on the hoisting assembly. The hoisting assembly is provided with a driving assembly for driving the first rotating ring to rotate. A second rotating ring is rotatably mounted inside the first rotating ring. The central axes of the first rotating ring and the second rotating ring are intersected. A fixing assembly for fixing the electroplating fixture is provided inside the second rotating ring. An electrolytic ultrasonic mechanism is installed inside a cleaning tank; the electrolytic ultrasonic mechanism includes several ultrasonic transmitters fixedly installed in an array on the side wall of the cleaning tank, and several electrode plates fixedly installed in an array at the bottom of the cleaning tank. The spherical roller mechanism flips the electroplating rack, and the electrolytic ultrasonic mechanism performs ultrasonic and electrolytic cleaning on the electroplating rack.

[0006] Preferably, the hoisting assembly includes U-shaped frames symmetrically arranged on the left and right sides of the cleaning tank. Straight rail rollers are slidably installed on the horizontal section of the U-shaped frame, and support plates are fixedly installed at the lower ends of the straight rail rollers on both sides.

[0007] Preferably, a movable component is provided at the lower end of the support plate. The movable component includes an electric slide rail fixedly installed at the lower end of the support plate. An electric hoist is fixedly installed at the movable end of the electric slide rail, and an equipment frame is fixedly installed at the output end of the electric hoist.

[0008] Preferably, the drive assembly includes a first motor fixedly installed in the equipment frame, the output end of the first motor being fixedly connected to a first rotating ring, and a second motor fixedly installed on the outer ring wall of the first rotating ring, the output end of the second motor being fixedly connected to a second rotating ring.

[0009] Preferably, the fixing component includes springs fixedly installed on the inner ring wall of the second rotating ring in a circumferential array, and a fixing hook is fixedly installed on the end of the spring away from the second rotating ring.

[0010] Preferably, the cleaning tank is provided with a liquid supply assembly, which includes a first liquid pump fixedly installed on the cleaning tank, and an inlet pipe is fixedly installed at the output end of the first liquid pump.

[0011] Preferably, the cleaning tank is further provided with a cleaning component, which includes a second liquid pump fixedly installed on the cleaning tank, a cleaning box fixedly installed on the cleaning tank, the cleaning box being connected to the cleaning tank through a connecting pipe, and a connecting pipe being fixedly installed between the second liquid pump and the cleaning box.

[0012] Preferably, the bottom of the cleaning tank is an inclined surface, and several electrode plates are fixedly installed on the inclined surface of the cleaning tank. A filter plate is fixedly installed inside the cleaning tank.

[0013] Preferably, the electrode sheet is provided with a scraping assembly, which includes an electric push rod fixedly installed at the lower end of the cleaning tank. The telescopic end of the electric push rod is fixedly installed with a scraping frame located in the cleaning tank, and the scraping frame has scraping openings that correspond one-to-one with the electrode sheet.

[0014] Preferably, a method for cleaning residual copper foil from electroplating racks, based on the electroplating rack residual copper foil cleaning device described above, includes the following steps: S1: Fixed hanger: The electroplating hanger is suspended in the spherical roller mechanism by a fixed component; S2: Immersion in cleaning solution: Using the hoisting assembly, the spherical roller mechanism with the hanging fixture is immersed in the electrolyte in the cleaning tank; S3: Combined cleaning: The spherical roller mechanism flips the hanger in the electrolyte and simultaneously starts the ultrasonic transmitter and electrode plate to perform ultrasonic cavitation and electrochemical stripping on the copper foil remaining on the hanger, so that the residual copper foil falls off the hanger surface. S4: Impurity separation: The stripped copper foil debris gathers downwards along the bottom slope of the cleaning tank. The impurity removal component is activated to pump the debris-containing liquid into the impurity removal box for filtration and interception of copper foil impurities. S5: Cleaning Electrode: During cleaning intervals, activate the scraping assembly to scrape away deposits adhering to the electrode surface, maintaining electrode activity; S6: Remove the hanger: Lift the spherical roller cage mechanism and the cleaned hanger out of the liquid surface. After the hanger has been fully deliquescent, use the hoisting components to move it to the unloading position and remove the hanger to complete the cleaning.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by the staggered rotation of the central axes of the first and second rotating rings, the electroplating rack can be rotated in space with multiple degrees of freedom, so that any part of the rack faces the ultrasonic source and the electrode in sequence, ensuring that the residual copper foil is fully cleaned and eliminating the cleaning blind spots. At the same time, the ultrasonic transmitter and the electrode plate work together to combine the physical peeling force generated by the ultrasonic cavitation effect with the chemical peeling generated by the electrolysis, which greatly shortens the copper foil peeling time and improves the cleaning efficiency. Furthermore, the hoisting component can directly hoist and lift the spherical roller mechanism and the rack, which facilitates the quick clamping and removal of the rack, reduces the intensity of manual operation, and improves the automation level of the process.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0028] Please see Figure 1 , Figure 2 and Figure 3 A device for cleaning residual copper foil from electroplating fixtures includes a cleaning tank 1, with a hoisting assembly 2 fixedly installed above the cleaning tank 1.

[0029] A spherical roller mechanism 3 is located below the hoisting assembly 2. The spherical roller mechanism 3 includes a first rotating ring 322 rotatably mounted on the hoisting assembly 2. The hoisting assembly 2 is provided with a driving assembly 32 for driving the first rotating ring 322 to rotate. A second rotating ring 323 is rotatably mounted inside the first rotating ring 322. The central axes of the first rotating ring 322 and the second rotating ring 323 are intersected. A fixing assembly 33 for fixing the electroplating fixture is provided inside the second rotating ring 323.

[0030] Please see Figure 1 , Figure 4 and Figure 5An electrolytic ultrasonic mechanism 4 is installed inside the cleaning tank 1. The electrolytic ultrasonic mechanism 4 includes several ultrasonic transmitters 43 fixedly installed in an array on the side wall of the cleaning tank 1, and several electrode plates 44 fixedly installed in an array at the bottom of the cleaning tank 1.

[0031] The spherical roller mechanism 3 flips the electroplating rack, and the electrolytic ultrasonic mechanism 4 performs ultrasonic and electrolytic cleaning on the electroplating rack.

[0032] In actual operation, the hoisting component 2 carries and guides the movement of the spherical roller mechanism 3 to ensure its stability during operation. The drive component 32 rotates the first rotating ring 322, whose rotation axis is vertical, while the rotation axis of the second rotating ring 323 is horizontal. This staggered arrangement allows the electroplating fixture fixed inside the second rotating ring 323 to achieve multi-axial flipping movement, so that all surfaces of the fixture can be exposed to the cleaning action.

[0033] The ultrasonic transmitter 43 uses a piezoelectric ceramic transducer, which is arranged uniformly along the side wall of the cleaning tank 1 to ensure that the ultrasonic energy can cover the entire cleaning area. The electrode plate 44 is made of stainless steel or titanium plate, which is arranged uniformly along the bottom of the cleaning tank 1 as an electrode for the electrolytic reaction, and works together with the electrolyte to treat the residual copper foil.

[0034] Thus, the spherical roller mechanism 3 achieves multi-axial rotation of the electroplating rack through the coordinated rotation of the first rotating ring 322 and the second rotating ring 323. At the same time, the electrolytic ultrasonic mechanism 4 performs joint cleaning of the residual copper foil on the electroplating rack through the cavitation effect generated by the ultrasonic transmitter 43 and the electrochemical stripping effect generated by the electrode sheet 44.

[0035] This enables multi-axial rotation of the electroplating rack, and with the synergistic effect of ultrasonic cavitation and electrochemical stripping of the electrolytic ultrasonic mechanism 4, it solves the problems of cleaning dead corners, insufficient copper foil stripping ability, long cleaning cycle, uneven cleaning or local over-corrosion that exist in traditional cleaning methods, and achieves comprehensive and efficient cleaning of residual copper foil on the electroplating rack.

[0036] Please see Figure 1 and Figure 2 The hoisting assembly 2 includes a U-shaped frame 21 symmetrically arranged on the left and right sides of the cleaning tank 1. A straight rail roller 22 is slidably installed on the horizontal section of the U-shaped frame 21, and a support plate 23 is fixedly installed at the lower end of the straight rail rollers 22 on both sides.

[0037] Please see Figure 2 A movable component 31 is provided at the lower end of the support plate 23. The movable component 31 includes an electric slide rail 311 fixedly installed at the lower end of the support plate 23. An electric hoist 312 is fixedly installed at the movable end of the electric slide rail 311, and an equipment rack 313 is fixedly installed at the output end of the electric hoist 312.

[0038] During actual operation, the straight rail roller 22 slides on the horizontal section of the U-shaped frame 21, allowing the spherical roller mechanism 3 to move horizontally, facilitating precise transfer between different work positions. The electric slide rail 311 enables the spherical roller mechanism 3 to move horizontally, facilitating accurate alignment and delivery of the fixed hanging device to the work position inside the cleaning tank 1. Moreover, after the cleaning operation is completed, the spherical roller mechanism 3 can be smoothly moved to the unloading position.

[0039] The electric hoist 312 can control the vertical lifting and lowering of the spherical roller mechanism 3, enabling it to precisely control the depth of the electrolyte immersed in the cleaning tank 1 according to the operation requirements, and to lift the hanger out of the liquid surface for dehydration after cleaning, avoiding friction or collision between the hanger and the edge of the cleaning tank 1.

[0040] Please see Figure 2 The drive assembly 32 includes a first motor 321 fixedly installed in the equipment frame 313. The output end of the first motor 321 is fixedly connected to the first rotating ring 322. A second motor 324 is fixedly installed on the outer ring wall of the first rotating ring 322. The output end of the second motor 324 is fixedly connected to the second rotating ring 323.

[0041] In actual operation, the first motor 321 drives the first rotating ring 322 to rotate, and the second motor 324 drives the second rotating ring 323 to rotate, so that the second rotating ring 323 can move synchronously with the first rotating ring 322. The central axes of the first rotating ring 322 and the second rotating ring 323 are intersected, and both can independently control their speed and direction. Therefore, it is possible to realize the continuous flipping action of the electroplating rack in the electrolyte in the cleaning tank 1 at multiple angles and directions.

[0042] This allows all parts of the complex structure of the electroplating rack, including dead corners that are difficult to reach by traditional methods, to be fully exposed and in full contact with the electrolyte, ultrasound, and electrolysis, thereby improving the cleaning effect of residual copper foil and ensuring that copper foil debris can be completely removed from the surface of the rack.

[0043] Please see Figure 2 , Figure 3 and Figure 7 The fixing component 33 includes a spring 331 fixedly installed on the inner ring wall of the second rotating ring 323 in a circumferential array, and a fixing hook 332 is fixedly installed on the end of the spring 331 away from the second rotating ring 323.

[0044] In actual operation, when the hanger is fixed, the spring 331 will extend and retract according to the actual size of the hanger, providing a flexible clamping force to avoid deformation or damage to the hanger frame that may be caused by rigid fixing. In addition, the combination design of the fixing hook 332 and the spring 331 makes the hanging process more convenient. The operator only needs to overcome the elastic force of the spring 331 to easily hang or remove the hanger, which greatly shortens the auxiliary operation time and improves the overall cleaning efficiency.

[0045] Moreover, the elastic properties of the spring 331 enable the fixing component 33 to automatically adapt to electroplating fixtures of different sizes and shapes, eliminating the need for frequent adjustments or replacements of the fixing device, thus improving the versatility and operational efficiency of the equipment.

[0046] Please see Figure 4 The cleaning tank 1 is provided with a liquid supply assembly 41, which includes a first liquid pump 411 fixedly installed on the cleaning tank 1, and an inlet pipe 412 fixedly installed at the output end of the first liquid pump 411.

[0047] In actual operation, the first liquid pump 411 can extract the stored electrolyte according to the actual cleaning operation needs. It can flexibly control the start and stop of the liquid supply and the liquid supply volume. The liquid inlet pipe 412 can accurately introduce the electrolyte extracted by the first liquid pump 411 into the cleaning tank 1, adapting to the liquid supply needs of different operation scales, and avoiding the problem of excessive liquid supply overflow or insufficient liquid supply affecting the cleaning effect.

[0048] Please see Figure 4 The cleaning tank 1 is also equipped with a cleaning component 42, which includes a second liquid pump 422 fixedly installed on the cleaning tank 1. A cleaning box 421 is fixedly installed on the cleaning tank 1. The cleaning box 421 is connected to the cleaning tank 1 through a connecting pipe. A connecting pipe is fixedly installed between the second liquid pump 422 and the cleaning box 421.

[0049] In actual operation, the second pump 422 can periodically extract the electrolyte containing copper foil debris from the cleaning tank 1 and transport it to the impurity removal box 421 through the connecting pipe. In the impurity removal box 421, copper foil impurities are filtered, precipitated or separated, thereby purifying the electrolyte. The purified electrolyte can be discharged back to the cleaning tank 1 to achieve electrolyte recycling, avoid copper foil impurities from being suspended in the cleaning tank 1 for a long time, and prevent interference with the synergistic effect of ultrasonic cavitation and electrochemical stripping, thus maintaining the cleaning efficiency and effect of the electrolytic ultrasonic mechanism 4.

[0050] Please see Figure 4 and Figure 5 The bottom of the cleaning tank 1 is inclined, and several electrode plates 44 are fixedly installed on the inclined surface of the cleaning tank 1. A filter plate 45 is fixedly installed inside the cleaning tank 1.

[0051] During actual operation, the inclined surface at the bottom of the cleaning tank 1 guides the peeled copper foil debris to automatically gather downwards along the inclined surface, facilitating the subsequent unified collection and processing of copper debris impurities and reducing the difficulty of the impurity removal operation. The filter plate 45 separates the area where the cleaning operation is carried out above from the area where impurities are deposited at the bottom. During the process of the spherical roller mechanism 3 flipping and stirring the hanger, the copper foil debris that has been deposited at the bottom of the tank will not be disturbed, preventing the separated debris from floating up again and re-attaching to the surface of the hanger, thus ensuring the cleaning effect of the hanger.

[0052] Please see Figure 5 , Figure 6 and Figure 8 The electrode plate 44 is provided with a scraping assembly 46. The scraping assembly 46 includes an electric push rod 463 fixedly installed at the lower end of the cleaning tank 1. The telescopic end of the electric push rod 463 is fixedly installed with a scraping frame 461 located in the cleaning tank 1. The scraping frame 461 has scraping openings 462 that correspond one-to-one with the electrode plate 44.

[0053] In specific operations, during the intervals of cleaning the electroplating fixtures, the electric push rod 463 is activated to drive the scraping frame 461 to reciprocate along the surface of the electrode plate 44. The inner wall of the scraping port 462 can closely adhere to and scrape the entire surface of the electrode plate 44, thereby thoroughly removing the copper deposits attached to the electrode plate 44. This solves the problem of decreased conductivity and weakened electrode activity caused by the accumulation of deposits on the surface of the electrode plate 44 during long-term electrolytic cleaning operations, ensuring that the electrolytic ultrasonic mechanism 4 can continuously and stably perform its electrochemical stripping function and maintain the stability and reliability of the cleaning effect.

[0054] Please see Figure 1-6 A method for cleaning residual copper foil from electroplating racks, based on the electroplating rack residual copper foil cleaning device described above, includes the following steps: S1: Fixed hanger: The electroplating hanger is suspended below the spherical rolling cage mechanism 3 by the hoisting component 2 and the moving component 31. The hanger is adaptively clamped by the springs 331 and the fixing hooks 332 arranged in the circumferential array on the inner ring wall of the second rotating ring 323.

[0055] S2: Immersion in cleaning solution: The equipment frame 313 is lowered by the electric hoist 312, so that the spherical roller mechanism 3 with the hanging fixture is immersed in the electrolyte in the cleaning tank 1. The first liquid pump 411 of the liquid supply component 41 replenishes the electrolyte to the cleaning tank 1 through the liquid inlet pipe 412 to ensure that the hanging fixture is completely submerged.

[0056] S3: Combined Cleaning: The first motor 321 and the second motor 324 of the drive assembly 32 are activated, driving the first rotating ring 322 to rotate around the vertical axis and the second rotating ring 323 to rotate around an axis intersecting the central axis of the first rotating ring 322, causing the hanger to freely rotate in multiple directions underwater. At the same time, the ultrasonic transmitter 43 and the electrode plate 44 are activated to perform a combined action of ultrasonic cavitation and electrochemical stripping on the rotating hanger, causing the residual copper foil to fall off the surface of the hanger.

[0057] S4: Impurity separation: The stripped copper foil debris gathers downward along the bottom slope of the cleaning tank 1 under the action of gravity. The liquid passes through the porous filter plate 45. The second liquid pump 422 of the impurity removal component 42 is started to pump the liquid containing debris into the impurity removal box 421 for filtration and interception of copper foil impurities. The clean liquid returns to the cleaning tank 1 through the connecting pipe to maintain the cleanliness of the electrolyte.

[0058] S5: Cleaning the electrode: During the cleaning interval, start the electric push rod 463 of the scraping assembly 46 to drive the scraping frame 461 to move back and forth along the surface of the electrode sheet 44. Use the scraping nozzle 462 to scrape and remove the deposits attached to the surface of the electrode sheet 44 by adhering to each electrode sheet 44, and maintain the electrode activity.

[0059] S6: Remove the hanger: Turn off the power to the ultrasonic transmitter 43 and electrode plate 44, stop the rotation of the first motor 321 and the second motor 324, lift the ball-shaped rolling cage mechanism 3 and the cleaned hanger out of the liquid surface by the electric hoist 312 and the electric slide rail 311, and after the hanger has been fully dehydrated, use the straight rail wheel 22 to move it horizontally along the U-shaped frame 21 to the unloading position, release the fixing hook 332 to remove the hanger, and complete the cleaning.

[0060] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
