Description

Technical Field

[0002] At present, in the field of ITO target manufacturing, the binding process is one of the key steps in target manufacturing. The binding process refers to pouring molten metal solder between the target and the back tube to achieve welding and fixation between the target and the back tube. The residual targets after use and defective products need to be unbound. The unbinding process will cause the molten metal solder poured during binding to melt again. These metal solders can be collected and reused, but at this time there will be a large amount of pollutants such as metal oxidation products and target debris in the solder and it cannot be used directly.

[0038] like Figure 4 and Figure 8 As shown, the scraping brush 382 includes a plurality of sleeve rods 3821, and the plurality of sleeve rods 3821 are sleeved in sequence, and a U-shaped scraper 3822 is fixedly connected to the top of the sleeve rod 3821, and two adjacent U-shaped scrapers 3822 are sleeved, and a symmetrical limiting groove 2 3823 is provided inside the sleeve rod 3821, and a slider 1 3824 is provided on the outer wall of two adjacent sleeve rods 3821, and the slider 1 3824 slides inside the adjacent sleeve rods 3821, and a circular scraper 3825 is fixedly connected to the top of the sleeve rod 3821 farthest from the end of the driving motor 381, and a group of sliders 2 3826 are fixedly connected to the top, and a ring groove 373 is provided inside the circular ring seat 37, and the sliders 2 3826 are slidably connected in the inner cavity of the ring groove 373;

[0039] When the driving motor 381 drives the sleeve rod 3821 to rotate, the slider 2 3826 will move in the annular groove 373, causing the multiple sleeve rods 3821 to contract or expand, so that the scraping brush 382 can scrape along the bottom surface of the filter screen 34, allowing the melted solder to fall faster, preventing the melted solder from clogging the filter screen holes.

[0040] like Figure 6 The top of the two connecting rods 332 are fixedly connected to the receiving box 331 through the connecting bolts 333. The top of the two connecting rods 332 are fixedly connected to the receiving box 331, and one of the connecting rods 334 has an internal thread. The lower end of the driving rod 351 is provided with a second thread 353.

[0043] Working principle of the present invention: When the present invention is used, firstly, the welding waste is put into the indium holding cylinder 2, and then the indium holding cylinder 2 falls into the top surface of the filter 34, and then the plurality of heating tubes 8 are started for heating, and then the side door 9 and the top door 10 are closed, so that the filter box 1 is a sealed device to prevent heat from dissipating, and the welding waste falling into the top surface of the filter 34 is melted, and at the same time, the driving motor 381 is started, and the scraping brush 382 is driven by the driving motor 381 to rotate, and the solution on the bottom surface of the filter 34 is scraped by the rotation of the scraping brush 382, ​​and then falls into the conical cylinder 42 for collection, and after the melting is completed The servo motor inside the motor box 12 is started, and the output end of the servo motor drives the driving rod 351 to rotate, and the rotation of the driving rod 351 drives the thread 1 352 to rotate, and the thread 1 352 drives the semicircular gear 372 to rotate, and the semicircular gear 372 drives the rotating rod 371 to rotate, and the rotating rod 371 drives the annular seat 37 to rotate. At the same time, the sleeve ring 334 is driven to move through the thread 2 353, so that the receiving box 331 is close to the bottom surface of the filter screen 34, so that the impurities roll into the receiving device 33 for collection, and the welding waste can be put again;

[0044] When the solder solution falls into the conical cylinder 42, some fine impurities will also fall into the solder solution through the mesh of the filter 34. After the impurities fall into the bottom layer, they will be precipitated. Finally, by opening the valve, the molten solder will flow out through the drainage pipe 7, and can be cooled and reused.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
