[0002] Sorting equipment is an important type of equipment used to classify, separate, and screen materials. It is widely used in industries such as mining, chemical, food, metallurgy, and agriculture. Its main function is to effectively separate materials according to their different characteristics (such as shape, size, density, color, hardness, etc.) so that they can be processed or utilized later.

[0003] Prior art, such as utility model patent CN219003823U, discloses a sorting device comprising a jetting device and a nozzle strip for jetting a pressurized gaseous medium toward a flow of objects to sort objects and guide them toward at least two different predetermined destinations. The jetting device has multiple outlets, each having a base portion and a protrusion. The nozzle strip is fitted to the jetting device and has multiple nozzles, each nozzle having at least one flexible tongue and an internal channel, wherein, at rest, the circumference of a first base portion of the channel is substantially equal to or less than the outer circumference of the base portion of the outlet, to provide a snap-fit ​​connection when the nozzle is fitted to the outlet. The sorting device according to this invention facilitates nozzle strip replacement and allows for a reduced nozzle spacing configuration, thereby enabling efficient sorting of small particles.

[0004] In the existing technology, during the inspection of raw materials, microcracks in the raw materials and damage to the wafer suction device can cause single-crystal silicon to break. The residual fragments of the broken single-crystal silicon in the performance testing module area can lead to a large number of misjudgments in the images. As a result, the inspectors need to repeatedly test the single-crystal silicon, which seriously affects the inspection efficiency. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The adjustment structure 4 includes a fixed frame 401, which is fixedly connected to the conveyor belt 1. Two fans 402 are fixedly connected to one side of the inner wall of the fixed frame 401, and a baffle 403 is fixedly connected to one side of the fixed frame 401. Connecting frames 404 are fixedly connected to both sides of the fixed frame 401. A connecting groove 405 is opened on one side of the connecting frame 404, and a screw 407 is slidably connected to the inner wall of the connecting groove 405. The same collection box 406 is fixedly connected to the side of the two screws 407 that are close to each other. A fixed plate 408 is threadedly connected to the arc surface of the screw 407. A handle 409 is fixedly connected to one side of the collection box 406. The connecting frame 404 is an iron frame. By setting the adjustment structure 4, the residual fragments of broken monocrystalline silicon can be blown away, avoiding misjudgment of the image due to the obstruction of the fragments, and further improving the equipment. To improve work efficiency and reduce retesting due to misjudgment, the arc surface of the fixed plate 408 is provided with anti-slip textures 410. The anti-slip textures 410 are evenly distributed on the fixed plate 408, which can increase the friction of the fixed plate 408 and prevent the personnel from slipping their hands when rotating the fixed plate 408. A soft pad 411 is fixedly connected to one side of the fixed plate 408. The soft pad 411 is a rubber pad, which can prevent the fixed plate 408 from directly contacting the connecting frame 404, thereby preventing the connecting frame 404 from being worn. Magnets 412 are fixedly connected to both sides of the collection box 406. The magnets 412 and the connecting frame 404 are attracted to each other, which can make the collection box 406 and the connecting frame 404 more stable and prevent the collection box 406 from moving.

[0032] In the embodiments of this utility model, please refer to Figure 4The auxiliary structure 5 includes an electric actuator 501. A pusher frame 504 is fixedly connected to the output end of the electric actuator 501. A cable 502 is electrically connected to one side of the electric actuator 501, and an infrared detector 503 is electrically connected to the other end of the cable 502. The infrared detector 503 is fixedly connected to the conveyor belt 1. Two fixing blocks 505 are fixedly connected to the lower surface of the dirt detection platform 2. Telescopic rods 506 are fixedly connected to the sides of the two fixing blocks 505 that are close to each other. A positioning plate 507 is fixedly connected to the other end of the telescopic rod 506. A spring 508 is sleeved on the arc surface of the telescopic rod 506. The two ends of the spring 508 are fixedly connected to the positioning plate 507 and the fixing blocks 505, respectively. The lower surface of the positioning plate 507 is fixedly... A fixed connection limit plate 509 is provided. By setting an auxiliary structure 5, the misaligned monocrystalline silicon can be straightened, thereby avoiding the misalignment of the monocrystalline silicon from causing adverse effects on subsequent processing steps and improving processing accuracy and stability. A pulley 510 is rotatably connected to one side of the positioning plate 507. The arc surface of the pulley 510 is slidably connected to the push frame 504.

A protective cover 511 is fitted on the outside of the electric push rod 501. The protective cover 511 is fixedly connected to the dirt detection platform 2. The protective cover 511 can protect the electric push rod 501 and prevent dust from entering the inside of the electric push rod 501.

[0033] The working principle of the air knife cleaning device for sorting equipment provided by this utility model is as follows: By setting the adjustment structure 4, when the monocrystalline silicon is conveyed on the conveyor belt 1, it will pass through the dirt detection platform 2. At this time, the detection probe 3 on the dirt detection platform 2 will detect dirt such as fragments. Then, the fan 402 in the fixed frame 401 can be started to blow away the fragments on the monocrystalline silicon. When the fragments hit the baffle 403, the fan 402 is turned off. At this time, the fragments will fall into the collection box 406. When the collection box 406 is full of fragments, the fixed plate 408 on the screw 407 is rotated with the help of the anti-slip texture 410, so that the fixed plate 408 and the bearing are connected. The connecting frame 404 is separated, and then the handle 409 is moved to move the collection box 406, causing the collection box 406 to disengage the screw 407 from the connecting groove 405. Then, the fragments in the collection box 406 are poured into the designated position. The anti-slip texture 410 can increase the friction of the fixing plate 408 and prevent the personnel from slipping when rotating the fixing plate 408. The soft pad 411 can prevent the fixing plate 408 from directly contacting the connecting frame 404, thereby preventing the connecting frame 404 from being worn. The magnet 412 can make the collection box 406 and the connecting frame 404 more stable and prevent the collection box 406 from moving.

[0034] By setting up auxiliary structure 5, when the monocrystalline silicon is conveyed on conveyor belt 1, infrared detector 503 will detect it and send a signal to electric push rod 501 through cable 502. At this time, the output end of electric push rod 501 will drive push frame 504 to move. When push frame 504 moves, the spring 508 on one side of fixed block 505 is in a stretched state. At this time, positioning plate 507 will drive telescopic rod 506 to move. At the same time, positioning plate 507 will drive limit plate 509 to move, so that limit plate 509 will straighten the misaligned monocrystalline silicon. Among them, pulley 510 can reduce the friction between positioning plate 507 and push frame 504, so that positioning plate 507 moves more smoothly. Protective cover 511 can protect electric push rod 501 and prevent dust from entering the inside of electric push rod 501.
