Description

Technical Field

[0001] This invention relates to the field of copper ion recovery technology, specifically to a copper ion electrolytic regeneration and copper recovery equipment after micro-etching. Background Technology

[0002] The copper ion electrolytic regeneration equipment after micro-etching is an environmentally friendly professional equipment mainly used in the printed circuit board (PCB) manufacturing industry. It is specifically designed to treat copper-containing waste liquid generated during the micro-etching process in PCB production. This waste liquid typically contains 15-30 g / L of copper ions and other components. The core function of the equipment is to extract metallic copper from the waste liquid through electrolysis so that it can be recycled, thereby achieving the dual goals of resource recovery and pollution reduction. The equipment can convert copper ions in the micro-etching waste liquid into high-purity electrolytic copper through the electrolysis process.

[0003] Regarding the aforementioned technologies, it is believed that during semiconductor processing, a large amount of copper-rich etching waste liquid is generated during the etching process. If this waste liquid is directly discharged, it will cause resource waste and environmental pollution. It is necessary to extract the copper ions from the waste liquid through electrolysis, and the resulting copper powder can be recycled and reused. However, after the copper powder adheres to the cathode plate during electrolytic recycling, it needs to be manually removed and the copper powder adhering to the surface scraped off.

[0004] However, this process has certain shortcomings. When scraping manually, the process of removing the cathode plate, scraping, and re-inserting it poses a risk of contact between the worker and the waste liquid. Furthermore, continuous work increases the labor intensity and affects the efficiency of subsequent copper powder collection. Summary of the Invention

[0005] The purpose of this invention is to provide a copper recycling and processing equipment for copper ion electrolytic regeneration after micro-etching, which solves the problems mentioned in the background art.

[0006] To achieve this objective, the present invention adopts the following technical solution: a copper ion electrolytic regeneration copper recovery treatment device after micro-etching, including a base, wherein a reaction frame for electrolytic recovery of copper ions from micro-etching waste liquid is installed at the center of the top wall of the base.

[0007] An electrolysis device for controlling the electrolysis reaction is installed on the top wall of the base and on the right side of the reaction frame;

[0008] A receiving frame is installed on the top wall of the base and on the left side of the reaction frame, and a collection frame for containing electrolytic copper powder is movably installed inside the receiving frame.

[0009] The reaction frame is equipped with a reaction component for electrolytic enrichment of copper ions in micro-etched waste liquid. The outer wall of the reaction frame is equipped with a moving component for laterally moving the reaction component. The top wall of the moving component is equipped with a clamping component for fixing the reaction component through a lifting component.

[0010] The outer wall of the lifting assembly is equipped with a cleaning component for scraping and collecting copper powder after copper ion electrolysis enrichment.

[0011] Furthermore, the reaction assembly includes several cathode plates installed in the inner cavity of the reaction frame for electrolytic enrichment reaction. Two mounting seats are fixedly installed on the top wall of each cathode plate, and the outer walls of the two mounting seats are provided with slots that are adapted to the clamping assembly and used for clamping and fixing.

[0012] Furthermore, positioning rings are fixedly installed on the front and rear parts of the top wall of the cathode plate, and cathode busbars are fixedly installed on the front and rear parts of the top wall of the reaction frame at the positions corresponding to the positioning rings. Positioning posts are fixedly installed on the top walls of several cathode busbars at the positions corresponding to the positioning rings. The outer walls of the positioning posts are all in contact with the inner walls of the corresponding positioning rings. The outer walls of several cathode busbars are all in contact with the outer walls of the corresponding positioning rings. Several cathode busbars are electrically connected to the cathode plate through the positioning rings. A fixing frame is installed inside the reaction frame.

[0013] Furthermore, the cleaning component includes two sets of mounting ears fixedly installed on the side wall of the movable component. Each set of mounting ears has two ears arranged symmetrically front to back. The inner wall of each mounting ear in the same set is rotatably mounted with a drive shaft. The rear ends of the two drive shafts are fixedly mounted with meshing gears through the movable component via bearings.

[0014] Furthermore, bogies are fixedly installed on the outer walls of both drive shafts, and triangular scrapers for scraping off the copper powder accumulated on the outer wall of the cathode plate by electrolysis are movably installed between the bogies. Several sliding rods are uniformly fixedly installed on the outer wall of the triangular scraper, and several sliding rods on the same side are fixedly installed with the same connecting seat. Several abutment springs are fixedly installed between the two connecting seats and the corresponding bogies.

[0015] Furthermore, a second gear is fixedly installed at the front end of the drive shaft on the left side through a bearing and moving assembly, and a rack adapted to the second gear is fixedly installed on the front wall of the receiving frame through an L-shaped seat. The rack and the second gear are located on the same meshing path.

[0016] Furthermore, the moving component includes a mounting bracket fixedly installed on the rear wall of the reaction frame. An adjusting screw is rotatably installed on the inner wall of the mounting bracket. A servo motor is fixedly installed on the side wall of the mounting bracket. The power shaft of the servo motor passes through the mounting bracket and is fixedly connected to the adjusting screw via a bearing. A slide block that slides on the inner wall of the mounting bracket is screwed onto the outer wall of the adjusting screw. A gantry frame is fixedly installed on the top wall of the slide block. The gantry frame is fixedly connected to the lifting component and the mounting lug. A sensor is fixedly installed on the inner wall of the gantry frame. Photoelectric sensors are fixedly installed on the outer wall of the reaction frame at the position corresponding to the cathode plate and at the middle position of the front wall of the receiving frame. The sensor is electrically connected to the photoelectric sensor.

[0017] Furthermore, a U-shaped frame is fixedly installed on both the front and rear walls of the reaction frame, and a limiting rod that slides through the gantry frame is fixedly installed on the inner wall of each U-shaped frame. The gantry frame can move linearly along the outer wall of the limiting rods installed at the front and rear.

[0018] Furthermore, the lifting assembly includes a lifting push rod fixedly installed on the top wall of the gantry frame. The movable end of the lifting push rod slides through the gantry frame and is fixedly installed with a lifting seat. The inner wall of the lifting seat is fixedly connected to the clamping assembly. Positioning rods are fixedly installed on the front and rear parts of the top wall of the lifting seat. The top ends of the two positioning rods slide through the gantry frame and extend to the outside.

[0019] Furthermore, the clamping assembly includes a drive motor fixedly installed on the front wall of the lifting seat, transmission rods rotatably installed on both sides of the inner wall of the lifting seat, and meshing gears fixedly installed at the rear ends of the two transmission rods through bearings through the lifting seat. The power shaft of the drive motor is fixedly connected to the corresponding transmission rod through the lifting seat through bearings. L-shaped card seats matching the card slots are fixedly installed on the front and rear parts of the outer walls of the two transmission rods. A control console for centralized control of the electrical control equipment of the entire device is installed on the left side of the base.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. The micro-etching copper ion electrolytic regeneration copper recycling equipment, when electrolyzing the etching waste liquid, causes the cathode plate installed inside the reaction frame to undergo an electrolytic reaction with the waste liquid. The copper ions in the waste liquid adhere to the surface of the cathode plate in the form of copper powder, realizing the rapid collection of the copper ions rich in the etching waste liquid. During the process of the cathode plate moving to the upper part of the collection frame, the surface of the cathode plate is formed into a state of adhesion to be scraped off by the scraper. As the cathode plate continues to move upward, the attached copper powder is scraped off by the scraper for unified collection. The entire collection process is fully automated, further reducing the risk of manual contact with waste liquid, and improving the labor intensity of workers and the labor cost of enterprises.

[0021] 2. The moving component of this micro-etched copper ion electrolytic regeneration copper recycling equipment is mainly used to accurately position the gantry and the fixed cathode plate. In cooperation with the clamping component, after the waste liquid electrolysis is completed, the gantry drives the clamping component to move quickly to the corresponding cathode plate and clamp it. The lifting component lifts the cathode plate from the reaction frame and moves it to the location of the collection frame. When the moving component is working, it can simultaneously drive the cleaning component to rotate and connect, so that the scraper contacts the cathode plate and scrapes it.

[0022] 3. The micro-etched copper ion electrolytic regeneration copper recycling equipment uses a screw that rotates to move the slide and gantry. The gantry moves the sensors one by one to the location of the photoelectric sensor and puts them into operation. This allows the entire device to be accurately positioned at the work station during the movement and to perform subsequent work such as clamping the cathode plate and collecting copper powder. This gives the entire device a good automation effect when switching work stations.

[0023] 4. This micro-etched copper ion electrolytic regeneration copper recycling equipment uses a drive motor to control the transmission rod to drive the L-shaped clamp to engage with the slot of the mounting base on the top wall of the cathode plate, thus fixing the cathode plate in place. This ensures that the cathode plate remains vertically stable during lifting and switching of work positions, preventing lateral swaying and copper powder residue when the copper powder is scraped off by the triangular scraper.

[0024] 5. The copper ion electrolytic regeneration copper recycling equipment after micro-etching is mainly driven by the gantry frame. The gear two meshes with the rack, which in turn drives the bogie and triangular scraper to turn closer to the cathode plate. It mainly starts to mesh and rotate when it reaches the location of the collection frame. After the cathode plate rises, the triangular scraper scrapes off the attached copper powder, thus completing the collection of copper powder.

[0025] 6. In this micro-etched copper ion electrolytic regeneration copper recycling equipment, the reaction components are set up by the cooperation of positioning columns and positioning rings, which mainly limit the position of the cathode plate so that it is always stably placed inside the reaction frame. The positioning ring is made of copper and is processed into a cathode busbar for electrical connection with the cathode plate.

[0026] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0044] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] Please see Figures 1-12 This invention provides a copper ion electrolytic regeneration copper recovery treatment device after micro-etching, including a base 1, and a reaction frame 11 for electrolytic recovery of copper ions from micro-etching waste liquid is installed at the center of the top wall of the base 1.

[0046] An electrolysis device 2 for controlling the electrolysis reaction is installed on the top wall of the base 1 and on the right side of the reaction frame 11;

[0047] A receiving frame 3 is installed on the top wall of the base 1 and on the left side of the reaction frame 11. A collection frame 10 for containing electrolytic copper powder is movably installed inside the receiving frame 3.

[0048] The reaction frame 11 is equipped with a reaction component 9 for electrolytic enrichment of copper ions in micro-etched waste liquid. The outer wall of the reaction frame 11 is equipped with a moving component 5 for lateral movement of the reaction component 9. The top wall of the moving component 5 is equipped with a clamping component 7 for fixing the reaction component 9 via a lifting component 6.

[0049] The outer wall of the lifting assembly 6 is equipped with a cleaning assembly 8 for scraping and collecting copper powder after copper ion electrolysis enrichment.

[0050] In this embodiment, after injecting the micro-etching waste liquid into the reaction frame 11, the components in the electrolysis device 2 and the reaction assembly 9 are started to begin the electrolysis reaction of the copper-rich waste liquid, so that the copper ions are attached to the surface of the cathode plate 91 in the form of copper powder, thus completing the electrolytic enrichment.

[0051] Next, the lifting assembly 6 and clamping assembly 7 are moved to the position of the corresponding cathode plate 91 by the moving assembly 5. The cathode plate 91, which has been attached with a certain amount of copper powder, is clamped by the clamping assembly 7, and the fixed cathode plate 91 is lifted by the lifting assembly 6 to get away from the reaction frame 11. The moving assembly 5 controls the cathode plate 91 to start moving to the position of the collection frame 10.

[0052] After the cathode plate 91 moves onto the collection frame 10, the triangular scraper 85 in the cleaning assembly 8 contacts the surface of the cathode plate 91. After the lifting assembly 6 lifts the cathode plate 91, the triangular scraper 85 scrapes off the attached copper powder, thereby completing the recovery and treatment of copper ions in the etching waste liquid.

[0053] Specifically, the reaction assembly 9 includes several cathode plates 91 installed in the inner cavity of the reaction frame 11 for electrolytic enrichment reaction. Two mounting seats 92 are fixedly installed on the top wall of each cathode plate 91. The outer side wall of each mounting seat 92 is provided with a slot 93 that is adapted to the clamping assembly 7 and used for clamping and fixing.

[0054] In this embodiment, after the cathode plate 91 is electrically connected to the cathode busbar 95 through the positioning ring 94, the copper ions in the waste liquid continuously form electrolytic copper powder under the electrolytic reaction and accumulate on the outer surface of the cathode plate 91, thereby forming the electrolytic copper recovery of copper ions in the waste liquid.

[0055] The mounting base 92 and the slot 93 provided on the top wall of the cathode plate 91 are mainly for the L-shaped mounting base 73 to be engaged. When it is necessary to switch the work position of the cathode plate 91 with copper powder attached, the slot 93 is engaged and fixed by the L-shaped mounting base 73 and then transferred by the moving component 5.

[0056] Specifically, positioning rings 94 are fixedly installed on the front and rear parts of the top wall of the cathode plate 91. Cathode busbars 95 are fixedly installed on the front and rear parts of the top wall of the reaction frame 11 at positions corresponding to the positioning rings 94. Positioning posts 96 are fixedly installed on the top walls of several cathode busbars 95 at positions corresponding to the positioning rings 94. The outer walls of the positioning posts 96 are all in contact with the inner walls of the corresponding positioning rings 94. The outer walls of several cathode busbars 95 are all in contact with the outer walls of the corresponding positioning rings 94. Several cathode busbars 95 are electrically connected to the cathode plate 91 through the positioning rings 94. A fixing frame 97 is installed inside the reaction frame 11. The fixing frame 97 has an installation groove 99 for installing the anode plate 98. The anode plate 98 is electrically connected to the external anode busbar.

[0057] In this embodiment, the positioning ring 94 is made of copper. Its main function is to provide a circuit connection channel between the cathode busbar 95 and the cathode plate 91. Secondly, the positioning ring 94 and the positioning post 96 work together to limit the position of the cathode plate 91, so that it is always inside the reaction frame 11 to complete the electrolysis reaction.

[0058] The fixture 97 installed inside the reaction frame 11 has an anode plate 98 electrically connected to the external anode busbar, forming the conditions required for the electrolysis reaction.

[0059] Specifically, the cleaning component 8 includes two sets of mounting ears 81 fixedly installed on the side wall of the movable component 5. Each set of mounting ears 81 has two ears arranged symmetrically front and back. The inner wall of the mounting ears 81 in the same set is rotatably mounted with a drive shaft 82. The rear ends of the two drive shafts 82 are fixedly mounted with meshing gears 83 through the movable component 5 via bearings.

[0060] In this embodiment, the main function of the cleaning component 8 is to scrape off the copper powder accumulated on the surface of the cathode plate 91, and to complete the unified collection of copper powder. The drive shaft 82 installed between the mounting ears 81 rotates in opposite directions through the meshing gear 83. The gear 83 drives the bogie 84 and the triangular scraper 85 to move closer to or away from the cathode plate 91.

[0061] Specifically, bogies 84 are fixedly installed on the outer walls of both drive shafts 82. Triangular scrapers 85 are movably installed between the bogies 84 to scrape off the copper powder accumulated on the outer wall of the cathode plate 91 by electrolysis. Several sliding rods 86 are evenly fixedly installed on the outer wall of the triangular scraper 85. Several sliding rods 86 located on the same side are fixedly installed with the same connecting seat 88. Several abutment springs 87 are fixedly installed between the two connecting seats 88 and the corresponding bogies 84.

[0062] In this embodiment, the initial state is that the bogie 84 and the triangular scraper 85 are kept vertical, and a lifting channel is formed between the drive shaft 82 for the lifting assembly 6 and the clamping assembly 7. When it contacts the cathode plate 91, the sharp corner area of ​​the triangular scraper 85 contacts the side wall of the cathode plate 91. At the same time, the sliding rod 86 drives the connecting seat 88 to extend outward, so that the abutment spring 87 is in a stretched state. Under the elastic action of the abutment spring 87, the triangular scraper 85 increases the contact pressure with the cathode plate 91.

[0063] Specifically, a second gear 89 is fixedly installed on the front end of the drive shaft 82 on the left side through the moving assembly 5 via a bearing, and a rack 811 adapted to the second gear 89 is fixedly installed on the front wall of the receiving frame 3 via an L-shaped seat 810. The rack 811 and the second gear 89 are located on the same meshing path.

[0064] In this embodiment, when the moving component 5 moves, it will drive the second gear 89 to approach and mesh with the rack 811 on the front wall of the receiving frame 3. After the second gear 89 rotates along the rack 811, it will drive the transmission shaft 82 and the meshing gear 83 to rotate in opposite directions, so that the triangular scraper 85 approaches the top of the cathode plate 91 to wait for the copper powder to be scraped off.

[0065] Specifically, the moving component 5 includes a mounting bracket 51 fixedly installed on the rear wall of the reaction frame 11. An adjusting screw 53 is rotatably installed on the inner wall of the mounting bracket 51. A servo motor 52 is fixedly installed on the side wall of the mounting bracket 51. The power shaft of the servo motor 52 passes through the mounting bracket 51 through a bearing and is fixedly connected to the adjusting screw 53. A slide block 54 that slides on the inner wall of the mounting bracket 51 is screwed onto the outer wall of the adjusting screw 53. A gantry frame 57 is fixedly installed on the top wall of the slide block 54. The gantry frame 57 is fixedly connected to the lifting component 6 and the mounting ear 81. A sensor 58 is fixedly installed on the inner wall of the gantry frame 57. A photoelectric sensor 59 is fixedly installed on the outer wall of the reaction frame 11 at the position corresponding to the cathode plate 91 and at the middle position of the front wall of the receiving frame 3. The sensor 58 and the photoelectric sensor 59 are electrically connected.

[0066] In this embodiment, the servo motor 52 drives the adjusting screw 53 to rotate, which in turn causes the slide block 54 to slide in the inner wall of the receiving frame 3, and causes the gantry frame 57 to slide along the outer wall of the limit rod 56. When the gantry frame 57 moves, it causes the sensor 58 to move to the position of the corresponding photoelectric sensor 59, so that the moving component 5 can accurately control the moving position of the gantry frame 57, complete the rapid automatic switching of the workstation, and improve the automation level of the entire device.

[0067] Specifically, U-shaped frames 55 are fixedly installed on the front and rear walls of the reaction frame 11, and limiting rods 56 that slide through the gantry frame 57 are fixedly installed on the inner walls of the U-shaped frames 55. The gantry frame 57 can move linearly along the outer walls of the limiting rods 56 installed at the front and rear.

[0068] In this embodiment, the limiting rod 56 installed inside the U-shaped frame 55 mainly functions to limit and support the movement path of the gantry frame 57, thereby increasing the overall strength of the gantry frame 57.

[0069] Specifically, the lifting assembly 6 includes a lifting push rod 61 fixedly installed on the top wall of the gantry frame 57. The movable end of the lifting push rod 61 slides through the gantry frame 57 and is fixedly installed with a lifting seat 62. The inner wall of the lifting seat 62 is fixedly connected to the clamping assembly 7. Positioning rods 63 are fixedly installed on the front and rear parts of the top wall of the lifting seat 62. The top ends of the two positioning rods 63 slide through the gantry frame 57 and extend to the outside.

[0070] In this embodiment, the lifting push rod 61 controls the lifting seat 62 and the cathode plate 91 fixed by the clamping assembly 7 to rise and fall, pushing the clamping assembly 7 down to fix the cathode plate 91. After the work station is transferred and switched, the cathode plate 91 is raised to complete the scraping and collection of copper powder attached to the surface of the cathode plate 91. The positioning rod 63 installed on the top wall of the lifting seat 62 mainly limits the movement path of the lifting seat 62 to prevent deviation and improve the path adaptation between the clamping assembly 7 and the cathode plate 91.

[0071] Specifically, the clamping assembly 7 includes a drive motor 71 fixedly installed on the front wall of the lifting seat 62. Transmission rods 72 are rotatably installed on both sides of the inner wall of the lifting seat 62. The rear ends of the two transmission rods 72 are fixedly installed with meshing gears 74 through the lifting seat 62 via bearings. The power shaft of the drive motor 71 is fixedly connected to the corresponding transmission rod 72 through the lifting seat 62 via bearings. L-shaped card seats 73 matching the card slots 93 are fixedly installed on the front and rear parts of the outer walls of the two transmission rods 72. A control console 4 for centralized control of the electrical control equipment of the entire device is installed on the left side of the base 1.

[0072] In this embodiment, the clamping component 7 is mainly used to clamp and fix the cathode plate 91 through the L-shaped card holder 73, maintain the cathode plate 91 in a stable posture during the process of transferring from the reaction frame 11 to the collection frame 10, control the descent stroke through the lifting push rod 61 so that the L-shaped card holder 73 matches the position of the card slot 93, and then drive the transmission rod 72 and the L-shaped card holder 73 through the drive motor 71 to clamp and fix the cathode plate 91, and control the entire electrical control equipment to work together through the control console 4.

[0073] The working principle of this device is as follows: Before operation, the electrolysis device 2, servo motor 52, sensor 58, photoelectric sensor 59, lifting push rod 61, drive motor 71, cathode plate 91, cathode busbar 95, anode plate 98 and external anode busbar are electrically connected through an external power supply and control console 4.

[0074] When the work starts, the semiconductor etching solution is injected into the reaction frame 11. Simultaneously, the cathode plate 91 and anode plate 98 located inside the reaction frame 11 are connected to the power supply through the corresponding cathode busbar 95 and the external anode busbar. The electrolysis device 2 is started so that the copper ions in the semiconductor etching solution of the reaction frame 11 continuously form electrolytic copper powder on the cathode plate 91 and continuously accumulate as the electrolysis reaction proceeds.

[0075] The working time is set by the control panel 4, so that the copper ions inside the etching solution are attached to the outer wall of the cathode plate 91 in the form of electrolytic copper powder. After the working time is reached, the servo motor 52 is started and the adjusting screw 53 is driven to rotate through its power shaft. As the adjusting screw 53 rotates continuously, it drives the slide 54 to slide in the inner wall of the mounting frame 51, and simultaneously drives the gantry 57 to move linearly along the limit rod 56 installed in the inner wall of the U-shaped frame 55. When the gantry 57 starts to move towards the electrolysis device 2 from the position of the receiving frame 3;

[0076] As the gantry 57 moves, the sensor 58 moves synchronously. When the sensor 58 moves to the cathode plate 91 close to the anode plate 98, the photoelectric sensor 59 at the corresponding position senses the sensor 58. Then, the control console 4 controls the servo motor 52 to stop working. Through the cooperation of the sensor 58 and the photoelectric sensor 59, the gantry 57 can accurately position itself to the corresponding cathode plate 91 when it moves.

[0077] The lifting push rod 61 pushes the lifting seat 62 to drive the positioning rod 63 to descend inside the gantry frame 57. The positioning rod 63 limits the movement path of the lifting seat 62 to prevent the lifting seat 62 from deviating during descent. After the lifting seat 62 drives the clamping assembly 7 to pass between the triangular scrapers 85, the moving end controlled by the lifting push rod 61 descends by a set stroke. At this time, the L-shaped card seat 73 is in the open state, and its position matches the position of the assembly seat 92 and the card slot 93.

[0078] The drive motor 71 is started to drive the transmission rod 72 and the two meshing gears 74 to rotate. In turn, the two transmission rods 72 drive the L-shaped bracket 73 to rotate in opposite directions and move closer to each other. The L-shaped bracket 73 gradually approaches the slot 93 on the mounting base 92 to form a clamp. After the L-shaped bracket 73 enters the slot 93, it completes the clamping and fixing of the cathode plate 91.

[0079] After the cathode plate 91 is fixed, the movable end of the lifting push rod 61 gradually retracts, causing the cathode plate 91 to move upward. The cathode plate 91 causes the positioning ring 94 to gradually disengage from the positioning column 96 and the cathode busbar 95, so that the cathode plate 91 is in the position of the corresponding triangular scraper 85. The servo motor 52 is started to drive the adjusting screw 53 to rotate, and the gantry 57 and the fixed cathode plate 91 continue to move towards the position of the receiving frame 3 according to the moving method of the moving component 5.

[0080] When the gantry 57 moves, it will drive the cleaning component 8 to move synchronously. When the abutment spring 87 drives the gear 2 89 to move close to the rack 811 installed on the top of the L-shaped seat 810 and form a meshing state with it, as the gantry 57 moves continuously, the gear 2 89 rotates along the path of the rack 811. When the gear 2 89 rotates, it will drive the drive shaft 82 and two meshing gears 1 83 to rotate. When the drive shafts 82 on both sides rotate in opposite directions between the mounting ears 81, they will drive the bogie 84 and the triangular scraper 85 to move closer to each other. When the triangular scraper 85 moves closer to the top of the side wall of the cathode plate 91 during the turning process, it will cause the bogie 84 and the triangular scraper 85 to move closer to each other.

[0081] When the gantry 57 drives the gear 89 to rotate continuously on the rack 811, after the photoelectric sensor 59 installed on the front wall of the receiving frame 3 senses the position of the sensor 58, the servo motor 52 stops working and the gantry 57 and gear 89 stop moving. At this time, the gantry 57 stops in the middle position between the receiving frame 3 and the collecting frame 10. As the triangular scraper 85 moves closer to the outer wall of the cathode plate 91, it will drive the sliding rod 86 to pass through the outer wall of the bogie 84 and stretch the abutment spring 87 to push the connecting seat 88 to move outward. Under the elastic action of the abutment spring 87, the triangular scraper 85 is precisely attached to the cathode plate 91.

[0082] The fixed cathode plate 91 and the copper powder attached to its surface are located at the upper part of the collection frame 10. The lifting seat 62, the clamping assembly 7 and the fixed cathode plate 91 are lifted by the retraction of the movable end of the lifting push rod 61. After the cathode plate 91 is scraped by the triangular scraper 85, the copper powder attached to the surface of the cathode plate 91 is scraped off into the collection frame 10 and collected.

[0083] Meanwhile, the scraped cathode plate 91 is returned to its original position through the cooperation of the moving component 5, the lifting component 6, the clamping component 7, and the cleaning component 8, and the remaining copper powder attached to the surface of the cathode plate 91 is scraped off and collected in the same manner as described above.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
