Description

Technical Field

[0001] This application relates to the field of electroplating metal cleaning technology, and in particular to a water-saving automatic cleaning device for copper plating processes. Background Technology

[0002] In the gravure printing industry, gravure rollers are a key component, and their quality directly affects the printing effect and quality. With the continuous development of printing technology, the performance requirements for gravure rollers are becoming increasingly stringent, such as higher wear resistance and better corrosion resistance. The manufacturing process of gravure rollers is relatively complex, involving multiple key steps. Optimization and improvement of each step contribute to enhancing the overall performance of the gravure roller, thereby driving the advancement of gravure printing technology and meeting the market's demand for high-quality printed products. At the same time, efficient operation of each process can also improve production efficiency and reduce production costs.

[0003] In traditional concave roller copper plating processes, the removal of excess plating solution from the steel pipe surface is typically achieved using a single-head, single-site, multiple-cleaning method. This method involves repeatedly cleaning the steel pipe at a specific location using a single cleaning head. Each cleaning operation covers only a small area, necessitating multiple repetitions to ensure cleaning effectiveness. While this method can meet basic cleaning requirements to some extent, its limitations make the entire cleaning process quite cumbersome.

[0004] Traditional single-head, single-area, multiple-cleaning methods have significant drawbacks. Their cleaning efficiency is extremely low because the single-head, single-area cleaning mode limits the cleaning range and speed; each cleaning cycle can only treat a localized area, requiring a considerable amount of time to complete the cleaning of the entire copper-plated steel pipe. Furthermore, this cleaning method consumes a huge amount of water; repeated cleaning inevitably leads to the consumption of large quantities of water resources, increasing production costs and contradicting current trends of energy conservation and environmental protection. Summary of the Invention

[0005] In order to improve the efficiency and effectiveness of cleaning excess plating solution adhering to the outside of copper-plated steel pipes, this application provides a water-saving automatic cleaning device for the copper plating process.

[0006] This application provides a water-saving automatic cleaning device for a copper plating process, which adopts the following technical solution: A water-saving automatic cleaning device for copper plating processes, comprising: A cleaning main frame, wherein a cleaning chamber for cleaning copper-plated tubes is provided inside the cleaning main frame, and a cover plate is provided on the top of the cleaning chamber; A spray assembly is provided, with multiple spray arms evenly spaced along the length of the cleaning chamber. Each spray assembly includes two spray arms arranged in a partially annular shape. The two spray arms are slidably connected circumferentially and can form a complete annulus. Each spray arm has a cavity inside, and a water inlet pipe is provided on one side of the cavity. The water inlet pipe is connected to an external water source. Multiple nozzles communicating with the cavity are evenly spaced along the inner side of the spray arm circumferentially. A rotating component is used to drive multiple spray components to reciprocate and swing along the central axis of the copper-plated tube. A translation component is used to drive multiple spray components to reciprocate along the length of the cleaning chamber; An opening and closing assembly is used to drive one of the spray arms in the spray assembly to rotate and open / close. Clamping assembly, used to fix both ends of the copper-plated tube along its length and suspend the copper-plated tube in the air; The lifting and centering assembly is used to adjust the clamping position of the copper-plated tube and the axial position of the copper-plated tube.

[0007] By adopting the above technical solution, when cleaning copper-plated steel pipes using an automatic cleaning device, the copper-plated steel pipe to be cleaned of excess plating solution is first placed on a lifting and centering assembly. The lifting and centering assembly then adjusts the axial position of the copper-plated steel pipe vertically to align it with the clamping part of the clamping assembly. Next, the clamping assembly fixes both ends of the copper-plated steel pipe along its length and suspends it in the air. Then, the opening and closing assembly drives one of the spray arms in the spray assembly to rotate and open, so that the two partially annular spray arms form a complete ring surrounding the copper-plated steel pipe. Subsequently, external water enters the cavity of the spray arm through the inlet pipe and is sprayed out from the nozzle to clean the copper-plated steel pipe. At the same time, the rotating assembly drives multiple spray assemblies to rotate back and forth. The oscillating and translating components drive multiple spray components to reciprocate along the length of the cleaning chamber, achieving multi-angle and multi-position cleaning. Specifically, the rotating component drives the spray components to rotate and oscillate, increasing the cleaning angle; the translating component moves the spray components along the length of the cleaning chamber, expanding the cleaning range; the opening and closing component facilitates opening or closing the spray arms, making it easy to insert or remove the copper-plated tube; and the clamping component fixes and suspends both ends of the copper-plated tube, facilitating all-around cleaning. This automated, multi-head, multi-site, and multi-angle cleaning method not only improves cleaning efficiency and more thoroughly cleans excess plating solution from the copper-plated tube surface, but also reduces water consumption and saves production costs compared to traditional single-head, single-site, multiple-cleaning methods.

[0008] Optionally, one of the spray arms in the spray assembly is designated as a support arm and the other as a movable arm. Both the support arm and the movable arm have a docking channel on their sides that are close to each other. When the support arm and the movable arm form a complete ring, the docking channels on one side of the two spray arms are connected. A limiting seat for limiting the rotation angle of the movable arm is fixed on the support arm.

[0009] By adopting the above technical solution, the spray arm is divided into a support arm and a moving arm and a docking channel is set. When the two form a complete ring, the docking channel is connected, which reduces the number of interfaces between the water inlet pipe and the external water source during the automatic cleaning process, thereby reducing the failure rate at the interface and improving the continuity of water supply.

[0010] Optionally, the translation component includes: The support base is fixed to the inner wall of the cleaning chamber; The drive motor is fixed to the support base. A rotating shaft is rotatably connected to the support base and is arranged vertically. One end of the rotating shaft is fixed to the output shaft of the drive motor, and the other end is fixedly fitted with a crank. A rocker arm is hinged to the end of the crank away from the axis of rotation; A movable seat is slidably connected to the inner wall of the cleaning chamber and hinged to the end of the rocker arm away from the crank. The rotating assembly is fixed to the movable seat.

[0011] By adopting the above technical solution, when the translation component drives multiple spray components to reciprocate along the length of the cleaning chamber, the drive motor first starts and drives the rotating shaft to rotate. The rotating shaft drives the crank to rotate, and when the crank rotates, it drives the moving seat to slide back and forth on the inner wall of the cleaning chamber through the rocker arm. Since the rotating component is fixed on the moving seat, the reciprocating sliding of the moving seat will drive the rotating component to move back and forth along the length of the cleaning chamber, thereby driving multiple spray components to move back and forth along the length of the cleaning chamber. This translation component can drive the spray components to move back and forth along the length of the cleaning chamber, so that the spray components can clean different positions of the copper-plated tube, expand the cleaning range, avoid cleaning dead corners, effectively improve cleaning efficiency, realize a multi-head, multi-site automated cleaning mode, and reduce water consumption.

[0012] Optionally, the rotating component includes: The first support frame is fixed to the movable seat and is provided in multiple ways. The multiple first support frames correspond one-to-one with the multiple support arms, and the first support frame and the support arm are slidably connected in the circumferential direction. The second support frame is fixed to the movable seat. A swing shaft is rotatably connected to the second support frame. Multiple reciprocating gears corresponding to the multiple support arms are fixedly sleeved on the swing shaft along its length. An incomplete annular reciprocating gear ring is fixed on the support arm, and the reciprocating gear meshes with the reciprocating gear ring; A power shaft is rotatably connected to the second support frame, and a power motor is also fixed on the second support frame. One end of the power shaft is fixed to the output shaft of the power motor, and a rotating arm is fixedly sleeved on the other end. A swing arm is fixed to the swing axis, and the swing arm is arranged perpendicular to the swing axis; A sliding rod is fixed to the end of the swing arm away from the swing axis, and the sliding rod is arranged parallel to the swing axis; A drive sleeve is fitted onto the outside of the sliding rod, and the drive sleeve can both slide along its own axis and rotate. A rotating shaft is fixed to the outside of the drive sleeve and is arranged perpendicular to the axis of the drive sleeve. The end of the rotating arm away from the power shaft is sleeved to the outside of the rotating shaft. The rotating arm can both slide along the axis of the rotating shaft and rotate.

[0013] By adopting the above technical solution, when the rotating component drives the spray component to reciprocate and swing along the central axis of the copper-plated pipe for cleaning, the power motor first drives the power shaft to rotate, the power shaft drives the rotating arm to rotate, the rotating arm drives the swing arm to swing through the drive sleeve and sliding rod, the swing arm drives the swing shaft to swing, the swing shaft drives the reciprocating gear to rotate, the reciprocating gear meshes with the incomplete annular reciprocating gear ring on the support arm, thereby driving the support arm to slide circumferentially on the first support frame, realizing the reciprocating and swinging of multiple spray components; this rotating component can drive multiple spray components to reciprocate and swing, so that the nozzles clean the copper-plated steel pipe from different angles. Compared with the traditional single-head single-site multiple cleaning method, it can cover a larger cleaning range, comprehensively clean the excess plating solution generated by copper plating on the surface of the copper-plated pipe, and improve cleaning efficiency.

[0014] Optionally, the opening and closing component includes: A drive shaft is rotatably connected between the plurality of support arms; A drive gear is fixedly sleeved on the drive shaft and there are multiple drive gears, each of which corresponds to one of the multiple moving arms; a partially annular driven gear ring is fixed on the support arm, and the drive gear and the driven gear ring mesh with each other.

[0015] By adopting the above technical solution, the moving arm is opened or closed by the opening and closing component, which facilitates the insertion or removal of copper-plated tubes. First, multiple drive gears fixedly sleeved on the drive shaft will rotate together with the drive shaft. Since multiple drive gears correspond one-to-one with multiple moving arms, and the incomplete annular driven gear ring fixed on the support arm meshes with the drive gears, the rotation of the drive gears will drive the meshing driven gear ring to move, thereby causing the moving arm to rotate relative to the support arm to achieve opening and closing. This opening and closing component can conveniently control the opening and closing of the two spray arms in the spray assembly, which facilitates the insertion and removal of copper-plated tubes and improves the convenience, flexibility and working efficiency of the device.

[0016] Optionally, the opening and closing component further includes: A ratchet is fixedly sleeved on the outside of the drive shaft, and a pawl is rotatably connected to one of the support arms, the pawl engaging with the ratchet; A compression spring is fixed to the side of the pawl away from the ratchet to give the pawl a pushing force toward the ratchet, and the other end of the compression spring is fixed to the support arm.

[0017] By adopting the above technical solution, when the drive shaft rotates, the ratchet rotates accordingly. The pawl, which meshes with the ratchet, abuts against the ratchet under the action of the compression spring. Because the compression spring provides a pushing force to the pawl towards the ratchet, the pawl will perform a one-way locking action as the ratchet rotates. When it is necessary to open or close the moving arm in the spray assembly, the pawl is unlocked away from the ratchet, separating the ratchet from the pawl. This allows the drive shaft to rotate in the opposite direction, causing the drive gear to reverse, which in turn causes the driven gear ring to move the support arm, thus achieving opening and closing. The one-way locking function of the ratchet and pawl prevents the drive shaft from accidentally reversing due to vibration or other factors, improving the stability and reliability of the opening and closing action and ensuring that the spray assembly can accurately perform its opening and closing function.

[0018] Optionally, sealing rings are fixed to the sides of the two docking channels on the support arm and the movable arm that are close to each other.

[0019] By adopting the above technical solution, the sealing ring can improve the sealing performance of the docking channels of the support arm and the moving arm on the side that are close to each other, reduce liquid leakage, and further improve the cleaning effect and water-saving performance.

[0020] Optionally, the lifting and centering assembly includes multiple electric telescopic rods fixed inside the cleaning chamber and arranged vertically, and a support ring fixed to the output end of the electric telescopic rods and arranged in a semi-circular shape; Multiple electric telescopic rods are spaced apart in the horizontal direction, and multiple clearance holes adapted to the support ring are spaced apart on the movable base.

[0021] By adopting the above technical solution, the electric telescopic rod can drive the semi-circular support ring to move up and down, thereby adjusting the clamping position of the copper-plated tube. At the same time, because the support ring is semi-circular, when the copper-plated tube is placed above multiple semi-circular support rings, the copper-plated tube will automatically center itself, making the axis of the copper-plated tube collinear or parallel with the axes of the multiple semi-circular support rings, thus facilitating the positioning and clamping of the inner hole of the copper-plated tube by the clamping assembly. Meanwhile, the moving base is provided with clearance holes that are compatible with the support ring, avoiding interference between the lifting and centering assembly and the moving base when the assembly is working.

[0022] Optionally, the clamping assembly includes two linear motors symmetrically fixed inside the cleaning chamber, a clamping seat fixed above the sliders of the two linear motors, and a clamping block detachably connected to one side of the two clamping seats that are close to each other.

[0023] By adopting the above technical solution, the clamping seat is driven by a linear motor, and the clamping block can be used to conveniently and quickly fix both ends of the copper-plated tube along its length and suspend it in the air, thus achieving stable clamping.

[0024] Optionally, the clamping block is conical in shape, and a rubber pad is laid on the outside of the clamping block.

[0025] By adopting the above technical solution, the conical clamping block can adapt to the cleaning of copper-plated tubes of various sizes and specifications, and the rubber pad can reduce the damage of the clamping block to the inner hole of the copper-plated tube, thereby improving product quality.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Multiple spray components are arranged along the length of the cleaning chamber, and are driven to reciprocate by a rotating component and a translation component, which drives them to reciprocate along the length of the cleaning chamber, thereby expanding the cleaning range and speed and improving cleaning efficiency; 2. The spray assembly can be opened and closed via the opening and closing mechanism, which facilitates the insertion and removal of copper-plated tubes. At the same time, multiple spray nozzles thoroughly clean the copper-plated tubes, reducing the number of cleaning cycles and thus reducing water consumption. 3. The clamping assembly fixes both ends of the copper-plated tube, suspending it in the air. The lifting and centering assembly adjusts the clamping position and axis position of the copper-plated tube, ensuring the stability and accuracy of the copper-plated tube during the cleaning process and improving the cleaning effect.

[0029] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0030] This application discloses a water-saving automatic cleaning device for a copper plating process. (Refer to...) Figure 1 and Figure 2 The water-saving automatic cleaning device for the copper plating process includes a cleaning main frame 1, a spray assembly 2, a rotating assembly 3, a translation assembly 4, an opening and closing assembly 5, a clamping assembly 6, and a lifting and centering assembly 7. Specifically, the cleaning main frame 1 provides support and housing space for the entire device. The cleaning main frame 1 has a cleaning chamber 11 for cleaning the copper-plated tubes 8. The top of the cleaning chamber 11 is equipped with a cover plate 12. The function of the cover plate 12 is to prevent water from splashing out during the cleaning process. The cover plate 12 is connected to the cleaning main frame 1 by sliding or by hinges, etc., for easy opening and closing.

[0031] Specifically, refer to Figures 2-4 Multiple spray assembly 2s are evenly spaced along the length of the cleaning chamber 11, and are responsible for spraying water to clean the copper-plated tubes 8. The spray assembly 2 includes two spray arms 21 arranged in a partially annular shape, which are slidably connected circumferentially to form a complete ring. Each spray arm 21 has an internal cavity 22, with a water inlet pipe 23 on one side connected to an external water source. Multiple nozzles 24, communicating with the interior of the cavity 22, are evenly spaced along the inner circumferential side of the spray arm 21. The partially annular design of the spray arm 21 facilitates opening and closing, making it convenient for inserting and removing the copper-plated tubes 8. The water inlet pipe 23 can be a flexible or rigid pipe. After connecting to an external water source, water enters the cavity 22 of the spray arm 21 through the water inlet pipe 23 and is then sprayed out from the nozzles 24. The nozzles 24 are connected to the spray arm 21 using a union joint, and different types of nozzles 24 can be selected and combined according to different cleaning requirements.

[0032] The rotating component 3 drives multiple spray components 2 to reciprocate along the central axis of the copper-plated tube 8, increasing the cleaning angle and expanding the cleaning range. The translation component 4 drives multiple spray components 2 to reciprocate along the length of the cleaning chamber 11, expanding the cleaning range. The opening and closing component 5 controls the rotation and opening / closing of one of the spray arms 21 in the spray components 2 to allow for the insertion and removal of the copper-plated tube 8. The clamping component 6 fixes both ends of the copper-plated tube 8 along its length and suspends it, facilitating all-around cleaning of the copper-plated tube 8. The lifting and centering component 7 adjusts the height and axial position of the copper-plated tube 8. Through the coordinated work of these components, the overall automated, multi-head, multi-site, and multi-angle cleaning method not only improves cleaning efficiency and more comprehensively cleans excess plating solution generated by copper plating on the surface of the copper-plated tube 8, but also reduces water consumption and saves production costs compared to the traditional single-head, single-site, and multiple-cleaning method.

[0033] When cleaning copper-plated steel pipes using an automatic cleaning device, the copper-plated steel pipes to be cleaned of excess plating solution are first placed on the lifting and centering assembly 7. The lifting and centering assembly 7 is used to adjust the axial position of the copper-plated steel pipes up and down so that the axial position of the copper-plated steel pipes is aligned with the clamping part of the clamping assembly 6. Then, the clamping assembly 6 is used to fix both ends of the copper-plated steel pipe 8 along its length and suspend it in the air. Then, the opening and closing assembly 5 drives one of the spray arms 21 in the spray assembly 2 to rotate and open, so that the two incompletely annular spray arms 21 form a complete ring surrounding the copper-plated steel pipe 8. Subsequently, external water enters the cavity 22 of the spray arm 21 through the water inlet pipe 23 and is sprayed out by the nozzle 24 to clean the copper-plated steel pipe 8. At the same time, the rotating assembly 3 drives multiple spray assemblies 2 to rotate and swing back and forth, and the translation assembly 4 drives multiple spray assemblies 2 to move back and forth along the length of the cleaning chamber 11 to achieve cleaning at multiple angles and positions.

[0034] Reference Figure 3 and Figure 4 In the spray assembly 2, one spray arm 21 is designated as a support arm 211, and the other as a movable arm 212. Both the support arm 211 and the movable arm 212 have a docking channel 25 on their adjacent sides. When the support arm 211 and the movable arm 212 form a complete ring, the docking channels 25 on one side of the two spray arms 21 are connected. A limiting seat 26 is fixed on the support arm 211 to limit the rotation angle of the movable arm 212. The docking channel 25 ensures smooth water flow between the two spray arms 21 when they form a complete ring, reduces the number of interfaces between the water inlet pipe 23 and the external water source, and lowers the failure rate at the interfaces. The limiting seat 26 prevents the movable arm 212 from rotating excessively, ensuring accurate docking of the docking channels 25 between the two spray arms 21. A sealing ring 27 is fixed on the side of the two docking channels 25 on the support arm 211 and the movable arm 212 that are close to each other. The sealing ring 27 can be made of rubber to improve the sealing performance of the docking channels 25 on the side of the support arm 211 and the movable arm 212 that are close to each other and reduce liquid leakage at the docking point.

[0035] Reference Figure 5 and Figure 6 The translation component 4 includes a support base 41, a drive motor 42, a rotating shaft, a crank 43, a rocker arm 44, and a movable base 45. The support base 41 is fixed to the inner wall of the cleaning chamber 11; the drive motor 42 is fixed to the support base 41. The rotating shaft is rotatably connected to the support base 41 and is vertically arranged. One end of the rotating shaft is fixed to the output shaft of the drive motor 42, and the other end is fixed to the crank 43. The rocker arm 44 is hinged to the end of the crank 43 away from the rotating shaft. The movable base 45 is slidably connected to the inner wall of the cleaning chamber 11 and is hinged to the end of the rocker arm 44 away from the crank 43. The rotating component 3 is fixed to the movable base 45.

[0036] When the translation component 4 drives multiple spray components 2 to reciprocate along the length of the cleaning chamber 11, the drive motor 42 is started first to drive the rotating shaft to rotate. The rotating shaft drives the crank 43 to rotate. The crank 43 drives the moving seat 45 to slide on the inner wall of the cleaning chamber 11 through the rocker arm 44, thereby realizing the reciprocating movement of the spray components 2 along the length of the cleaning chamber 11, cleaning different positions of the copper-plated tube 8, and expanding the cleaning range.

[0037] Reference Figure 6 and Figure 7The rotating assembly 3 includes a first support frame 301, a second support frame 302, a swing shaft 303, a reciprocating gear 304, a partially annular reciprocating gear ring 305, a power shaft 306, a power motor 307, a rotating arm 308, a swing arm 309, a sliding rod 310, a drive sleeve 311, and a rotating shaft 312. Multiple first support frames 301 are fixed to the movable seat 45, and each first support frame 301 corresponds to one of multiple support arms 211, with the first support frames 301 and support arms 211 slidingly connected circumferentially. The second support frame 302 is fixed to the movable seat 45, and the swing shaft 303 is rotatably connected to the second support frame 302. Multiple reciprocating gears 304 are fixedly sleeved along the length of the swing shaft 303, and each reciprocating gear 304 corresponds to one of the multiple support arms 211. The partially annular reciprocating gear ring 305 is fixed to the support arm 211, and the reciprocating gears 304 mesh with the reciprocating gear ring 305. A power shaft 306 is rotatably connected to a second support frame 302. A power motor 307 is fixed to the second support frame 302. One end of the power shaft 306 is fixed to the output shaft of the power motor 307, and the other end is fixed to a rotating arm 308. A swing arm 309 is fixed to a swing shaft 303 and is perpendicular to the swing shaft 303. A sliding rod 310 is fixed to the end of the swing arm 309 away from the swing shaft 303, and is parallel to the swing shaft 303. A drive sleeve 311 is sleeved on the outside of the sliding rod 310, and can slide and rotate along its own axis. A rotating shaft 312 is fixed to the outside of the drive sleeve 311 and is perpendicular to the axis of the drive sleeve 311. The end of the rotating arm 308 away from the power shaft 306 is sleeved on the outside of the rotating shaft 312, and can slide and rotate along the axis of the rotating shaft 312.

[0038] When the rotating component 3 drives the spray component 2 to reciprocate and swing along the central axis of the copper-plated pipe 8 for cleaning, firstly, the power motor 307 drives the power shaft 306 to rotate, the power shaft 306 drives the rotating arm 308 to rotate, the rotating arm 308 drives the swing arm 309 to swing through the drive sleeve 311 and the sliding rod 310, the swing arm 309 drives the swing shaft 303 to swing, the swing shaft 303 drives the reciprocating gear 304 to rotate, the reciprocating gear 304 meshes with the incomplete annular reciprocating gear ring 305 on the support arm 211, thereby driving the support arm 211 to slide circumferentially on the first support frame 301, realizing the reciprocating rotation and swing of multiple spray components 2; the rotating component 3 can drive multiple spray components 2 to reciprocate and swing, so that the nozzle 24 cleans the copper-plated steel pipe from different angles. Compared with the traditional single-head single-site multiple cleaning method, it can cover a larger cleaning range and comprehensively clean the excess plating solution generated by copper plating on the surface of the copper-plated pipe 8, improving cleaning efficiency.

[0039] Reference Figure 8 and Figure 9The opening / closing assembly 5 includes a drive shaft 51, a drive gear 52, a partially annular driven gear ring 53, a ratchet 54, a pawl 55, and a clamping spring 56. The drive shaft 51 is rotatably connected between multiple support arms 211. Multiple drive gears 52 are fixedly sleeved on the drive shaft 51, with each drive gear 52 corresponding to one of the multiple moving arms 212. The partially annular driven gear ring 53 is fixed to the support arm 211, and the drive gear 52 meshes with the driven gear ring 53. The ratchet 54 is fixedly sleeved on the outside of the drive shaft 51, and the pawl 55 is rotatably connected to one of the support arms 211, meshing with the ratchet 54. A clamping spring 56 is fixed to the side of the pawl 55 away from the ratchet 54 to provide a pushing force towards the ratchet 54. The other end of the clamping spring 56 is fixed to the support arm 211.

[0040] When the moving arm 212 is opened or closed by the opening and closing assembly 5 to facilitate the insertion or removal of the copper-plated tube 8, the multiple drive gears 52 fixedly sleeved on the drive shaft 51 will rotate together with the drive shaft 51. Since the multiple drive gears 52 correspond one-to-one with the multiple moving arms 212, and the incompletely annular driven gear ring 53 fixed on the support arm 211 meshes with the drive gears 52, the rotation of the drive gears 52 will drive the meshing driven gear ring 53 to move, thereby causing the moving arm 212 to rotate relative to the support arm 211 to achieve opening and closing. At the same time, when the drive shaft 51 rotates, the ratchet 54 rotates accordingly. Since the compression spring 56 gives the pawl 55 a pushing force towards the ratchet 54, the pawl 55 will perform a one-way locking action as the ratchet 54 rotates. When the movable arm 212 in the spray assembly 2 needs to be opened or closed, the pawl 55 is unlocked to the side away from the ratchet 54, separating the ratchet 54 from the pawl 55. This allows the drive shaft 51 to rotate in the opposite direction, causing the drive gear 52 to reverse, which in turn causes the driven gear ring 53 to move the support arm 211, thus achieving opening and closing. The one-way locking function of the ratchet 54 and the pawl 55 prevents the drive shaft 51 from accidentally reversing due to vibration or other factors, improving the stability and reliability of the opening and closing action and ensuring that the spray assembly 2 can accurately perform the opening and closing function.

[0041] Reference Figure 5 and Figure 6 The lifting and centering assembly 7 includes multiple electric telescopic rods 71 ​​fixed inside the cleaning chamber 11 and arranged vertically, and a support ring 72 fixed to the output end of the electric telescopic rods 71 ​​and arranged in a semi-circular shape. The multiple electric telescopic rods 71 ​​are spaced apart in the horizontal direction, and the movable seat 45 is provided with multiple clearance holes 451 that are adapted to the support ring 72.

[0042] The electric telescopic rod 71 can drive the semi-circular support ring 72 to move up and down, thereby adjusting the clamping position of the copper-plated tube 8. Since the support ring 72 is semi-circular, when the copper-plated tube 8 is placed above multiple semi-circular support rings 72, the copper-plated tube 8 will automatically center itself, making the axis of the copper-plated tube 8 collinear or parallel with the axis of the multiple semi-circular support rings 72, which facilitates the positioning and clamping of the inner hole of the copper-plated tube 8 by the clamping assembly 6. At the same time, the moving seat 45 is provided with a clearance hole 451 that matches the support ring 72 to avoid interference with the moving seat 45 when the lifting and centering assembly 7 is working.

[0043] Reference Figure 8 The clamping assembly 6 includes two linear motors 61 symmetrically fixed within the cleaning chamber 11, clamping seats 62 fixed above the sliders of the two linear motors 61, and clamping blocks 63 detachably connected to the sides of the two clamping seats 62 that are close to each other. The clamping blocks 63 are conical in shape, and rubber pads are laid on the outer side of the clamping blocks 63. The linear motors 61 drive the clamping seats 62 to move, thereby clamping the copper-plated tube 8. The conical clamping blocks 63 can better accommodate copper-plated tubes 8 of different diameters, and the rubber pads can increase friction and prevent the copper-plated tube 8 from shaking during the cleaning process.

[0044] The implementation principle of the water-saving automatic cleaning device for the copper plating process in this application embodiment is as follows: This water-saving automatic cleaning device for the copper plating process achieves efficient and water-saving cleaning of the copper plating tube 8 through the coordinated work of multiple components. The multiple sets of spray components 2, along with their rotational and translational movements, expand the cleaning range, reduce the number of cleaning cycles, and improve cleaning efficiency. Simultaneously, the opening and closing component 5 facilitates the insertion and removal of the copper plating tube 8, while the clamping component 6 and the lifting and centering component 7 ensure the stable fixation and accurate positioning of the copper plating tube 8. The components work together to form a complete cleaning system, which significantly improves cleaning efficiency and reduces water consumption compared to the traditional single-head, single-site, multiple-cleaning method, aligning with the trend of energy conservation and environmental protection.

[0045] The above are all preferred 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.
