Description

Technical Field

[0001] This utility model relates to the field of printed circuit board technology, and in particular to an automatic screening device for cleaning copper balls using circulating chemicals. Background Technology

[0002] In the circuit board manufacturing process, copper plating is used to metallize and thicken the holes. Copper plating solutions and soluble anodes (copper balls) are used to plate copper onto the circuit board through ion exchange. The copper balls used in production contain phosphorus, which causes an insoluble black film to form on their surface during production. With continuous replenishment of copper balls, a large amount of this black film accumulates inside the titanium basket, affecting the uniformity of copper plating. The solution to this problem is to regularly clean and maintain the anode bag and copper balls.

[0003] In the existing technology, in order to recycle the acid after cleaning the copper balls, the acid needs to be filtered. Since the acid after cleaning carries a lot of impurities, a large amount of impurities will accumulate on the surface of the filter structure, causing blockage. This results in a significant decrease in the acid filtration efficiency, obstruction of the circulation path, and affects the continuous operation of the cleaning process. It is necessary to stop the machine, disassemble the filter cartridge, and clean it manually, which is time-consuming and labor-intensive. Utility Model Content

[0004] This utility model discloses an automatic screening device for cleaning copper balls in a chemical circulation system, which aims to solve the technical problem that after filtering acidic solutions carrying a lot of impurities, a large amount of impurities will accumulate on the surface of the filter structure, causing blockage and affecting the filtration efficiency and acid circulation effect.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic screening device for cleaning copper balls using circulating chemicals, comprising a main housing; a conical cylinder fixedly connected to the interior of the main housing; a movable cylinder rotatably connected to the interior of the main housing, one end of which is movably connected to the conical cylinder; an acid pickling chamber located inside the main housing; a partition fixedly connected to the inner wall of the acid pickling chamber; a filter cartridge fixedly connected to the partition; and a cleaning module located inside the acid pickling chamber, the cleaning module including a mounting frame fixedly connected to the inner wall of the acid pickling chamber, the mounting frame having a rotating hole for rotating within it. The system includes a movable ring component, with an annular tube fixedly connected to its inner wall. Multiple cleaning nozzles are fixedly connected at equal intervals around the annular tube. The cleaning module also includes a hydraulic rod, which is fixedly connected to the bottom of the mounting frame. A toothed rod is fixedly connected to the drive end of the hydraulic rod, and a toothed ring is fixedly connected to the outside of the movable ring component. The toothed ring meshes with the toothed rod. Multiple scraping components are fixedly connected at equal intervals around the outer wall of the movable ring component near the filter cartridge, and all scraping components are in close contact with the outer wall of the filter cartridge. A delivery pump is fixedly connected to the bottom of the mounting frame. A connecting pipe is fixedly connected to the output end of the delivery pump, with the end of the connecting pipe away from the delivery pump connected to the annular tube. A delivery pipe is fixedly connected to the input end of the delivery pump.

[0006] Equipped with a cleaning module, the pump delivers the filtered acid solution from the bottom through the delivery and connecting pipes into the annular pipe. The solution is then sprayed onto the filter cartridge via cleaning nozzles to wash away impurities adhering to the exterior. Simultaneously, a hydraulic rod reciprocates, pushing and pulling a toothed rod. The meshing of the toothed rod and toothed ring rotates the movable ring, forcing it to scrape the outer wall of the filter cartridge, removing accumulated impurities. This system effectively removes impurities from the filter cartridge surface, preventing clogging and ensuring continuous and stable operation. It also reduces the workload of disassembling and cleaning the filter cartridge, improving the reliability and lifespan of the filtration system.

[0007] In a preferred embodiment, the main housing has a washing chamber, a first discharge chamber, and a second discharge chamber inside. Both the first and second discharge chambers are fixedly connected to discharge hoppers. Multiple discharge holes (I and II) are equidistantly spaced on the movable cylinder. A spray pipe (I) is fixedly connected inside the pickling chamber, and multiple spray nozzles (I) are equidistantly connected to the spray pipe (I). Similarly, a spray pipe (II) is fixedly connected inside the washing chamber, and multiple spray nozzles (II) are equidistantly connected to the spray pipe (II). The main housing is fixedly connected to one side of a liquid inlet pump 1 and a liquid inlet pump 2. The output ends of the liquid inlet pump 1 and the liquid inlet pump 2 are respectively connected to spray pipe 1 and spray pipe 2. The input ends of the liquid inlet pump 1 and the liquid inlet pump 2 are respectively fixedly connected to an acid inlet pipe and a water inlet pipe. A drive motor is fixedly connected to one side of the main housing. An installation hole is opened on the movable cylinder. A rotating rod is fixedly connected in the installation hole. The end of the rotating rod away from the movable cylinder is rotatably connected to the conical cylinder. An agitator is fixedly connected to the outside of the rotating rod.

[0008] Equipped with spray pipe one, spray nozzle one, spray pipe two, spray nozzle two, and agitator, the liquid inlet pump one and liquid inlet pump two pump acid and clean water into spray pipe one and spray pipe two respectively through acid inlet pipe and water inlet pipe. During the movement of the copper balls, the copper balls are acid-washed and water-washed sequentially through spray nozzle one and spray nozzle two. At the same time, the drive motor drives the rotating rod to rotate, which drives the agitator to tumble the copper balls, so that the copper balls can receive more uniform cleaning. By setting up a movable cylinder, discharge hole one and discharge hole two, copper balls of different diameters can be screened through the corresponding discharge holes, realizing automatic sorting after cleaning, improving work efficiency and reducing manual operation.

[0009] As can be seen from the above, the automatic screening device for cleaning copper balls with circulating chemicals provided by this utility model, through the cleaning operation module, uses the filtered acid and scraping parts to wash and scrape off the impurities accumulated on the surface of the filter cartridge after filtration. Under the dual action, it can effectively remove the impurities accumulated on the surface of the filter cartridge, avoid the filter cartridge from being blocked by impurities, thus affecting the filtration efficiency and acid circulation effect, ensuring the continuous and stable operation of the equipment, reducing the workload of disassembling and cleaning the filter cartridge, and improving the reliability and service life of the filtration system.

[0015] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the main housing 1 has a washing chamber 8, a first discharge chamber 9, and a second discharge chamber 10 inside. Discharge hoppers 11 are fixedly connected to the interior of both the first discharge chamber 9 and the second discharge chamber 10. Multiple discharge holes 22 and 23 are equidistantly arranged on the circumference of the movable cylinder 3. A spray pipe 16 is fixedly connected inside the pickling chamber 7, and multiple spray nozzles 17 are equidistantly connected to the circumference of the spray pipe 16. A spray pipe 18 is fixedly connected inside the washing chamber 8, and multiple spray nozzles 19 are equidistantly connected to the circumference of the spray pipe 18. A liquid inlet pump 12 and a liquid inlet pump 23 are fixedly connected to one side of the main housing 1. The output ends of the liquid inlet pump 12 and the liquid inlet pump 23 are respectively connected to the spray pipe 16 and the spray pipe 28.

[0016] Working principle: The copper balls to be cleaned are poured into one end of the conical cylinder 2. Guided by the tapered shape of the conical cylinder 2, the copper balls move to the other end under gravity. Inlet pumps 12 and 13 are started, pumping acid and water into spray pipes 16 and 18 respectively through acid inlet pipe 14 and water inlet pipe 15. During the movement of the copper balls, they are acid-washed and water-washed sequentially through spray nozzles 17 and 19. Simultaneously, drive motor 4 rotates the rotating rod 20, causing the agitator 21 to agitate the copper balls, ensuring more even cleaning. After cleaning, the acid falls onto the baffle 6, is filtered through filter cartridge 24, and then falls to the bottom of the acid washing chamber 7. The filtered acid can be recycled. The transfer pump 509 is started to transfer the filtered acid from the bottom... The copper balls are pumped into the annular pipe 506 via the conveying pipe 511 and connecting pipe 510, and sprayed onto the filter cartridge 24 through the cleaning nozzle 507 to wash away the impurities attached to the outside of the filter cartridge 24. At the same time, the hydraulic rod 504 is activated to push and pull the toothed rod 505 back and forth. Through the meshing of the toothed rod 505 and the toothed ring 503, the movable ring 502 is driven to rotate, which forces the outer wall of the filter cartridge 24 to scrape away the impurities accumulated on the surface of the filter cartridge 24, so as to avoid the filter cartridge 24 from being blocked and affecting the filtration effect. After cleaning, the copper balls reach the movable cylinder 3. The drive motor 4 drives the movable cylinder 3 to rotate. Small-diameter copper balls are thrown out through the discharge hole 1 22, and large-diameter copper balls are thrown out through the discharge hole 23. The system can automatically screen and discharge copper balls of different diameter specifications, and then discharge them through the discharge hopper 11.
