Description

Technical Field

[0001] This utility model relates to the field of adhesive removal devices, and more specifically, to an adhesive removal device for processing single-crystal silicon rods. Background Technology

[0002] Monocrystalline silicon rods are cylindrical silicon bodies with perfect crystal lattice structures formed from high-purity polycrystalline silicon in a single crystal furnace through the Czochralski method or the zone melting method. They are the core basic materials of the semiconductor and photovoltaic industries. Their extremely high purity, absence of grain boundary defects, and excellent electrical properties ensure that the manufactured integrated circuits and solar cells have high efficiency, high reliability, and excellent stability.

However, while existing adhesive removal devices have basic adhesive removal functions, the nozzle position is usually fixed during spraying. This can easily lead to uneven spraying or even complete neglect of certain areas on the silicon rod, significantly affecting the adhesive removal efficiency and quality. Therefore, improvements are needed. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a desizing device for processing single crystal silicon rods, including a desizing box 1. A drive motor 2 is fixedly connected to the left side of the desizing box 1. A first rotating shaft 3 is fixedly sleeved at the other end of the output shaft of the drive motor 2. A cam 4 is fixedly sleeved at the other end of the first rotating shaft 3. A movable plate 5 is movably connected to the outer surface of the cam 4. A round rod 6 is fixedly connected to the front and rear sides of the right side of the movable plate 5. The other end of the round rod 6 passes through the desizing box 1 and extends into the inner cavity of the desizing box 1 and is fixedly connected to a flow divider 7. A nozzle 35 is fixedly connected to the inner side of the flow divider 7. An installation tube 11 is fixedly sleeved on the right side of the desizing box 1. The left end of the installation tube 11 passes through the desizing box 1 and extends into the interior of the desizing box 1 and is fixedly connected to a flow divider 10.

The outer surface of the left side of the first pipe 8 is fixedly sleeved with the inner surface of the flow divider 7.

[0018] When the drive motor 2 starts running, it will cause the first rotating shaft 3 to drive the cam 4 to rotate. At this time, the cam 4 will squeeze the movable plate 5, causing the movable plate 5 to drive the round rod 6 to move horizontally under the limiting action of the glue removal box 1, thereby causing the distributor 7 to drive the first pipe 8 to move horizontally to the left in the inner cavity of the second pipe 9.

[0019] Among them, a stainless steel spring 12 is movably sleeved on the outer surface of the round rod 6. The left side of the stainless steel spring 12 is fixedly connected to the right side of the movable plate 5, and the right side of the stainless steel spring 12 is fixedly connected to the left side of the glue removal box 1.

[0020] The design of the stainless steel spring 12 ensures that the movable plate 5 has a good reset effect during subsequent movements.

[0021] Among them, a metal bellows 13 is fixedly connected to the left side of the second pipe 9, and the other end of the metal bellows 13 is fixedly connected to the right side of the diverter 7.

[0022] Due to the design of the metal bellows 13, a dynamic seal is achieved between the distributor 7 and the second pipe 9, preventing the spray liquid from escaping when the first pipe 8 expands and contracts inside the second pipe 9.

[0023] The left side of the glue removal box 1 is fixedly connected to a power motor 14. The other end of the output shaft of the power motor 14 is fixedly sleeved with a second rotating shaft 15. The other end of the second rotating shaft 15 passes through the glue removal box 1 and extends to the outside of the glue removal box 1, and is fixedly sleeved with a first glue removal brush roller 16. The outer surface of the second rotating shaft 15 is fixedly sleeved with a first gear 17. The outer surface of the first gear 17 is meshed with a second gear 18.

The other end of the rotating rod 19 passes through the glue removal box 1 and extends to the inner cavity of the glue removal box 1, and is fixedly sleeved with a second glue removal brush roller 20.

[0024] When the power motor 14 starts running, it will drive the second rotating shaft 15 to drive the first degumming brush roller 16 and the first gear 17 to rotate synchronously, thereby driving the second gear 18, the rotating rod 19 and the second degumming brush roller 20 to rotate in the opposite direction.

[0025] Among them, a valve 21 is fixedly sleeved at the bottom right side of the glue removal box 1. A mounting bracket 26 and a fixing bracket 22 are fixedly connected to the left and right sides of the top of the glue removal box 1, respectively. A first motor 23 is fixedly connected to the top of the fixing bracket 22. A threaded rod 24 is fixedly sleeved at the other end of the output shaft of the first motor 23. The bottom end of the threaded rod 24 passes through the fixing bracket 22 and extends to the outside of the fixing bracket 22 and is movably sleeved with the top of the glue removal box 1. A connecting plate 25 is threadedly sleeved on the outer surface of the threaded rod 24. A limit rod 27 is movably sleeved on the left side of the connecting plate 25. The top of the limit rod 27 is fixedly sleeved inside the mounting bracket 26.

[0026] When the first motor 23 starts running, it will drive the threaded rod 24 to rotate. At this time, the connecting plate 25 will move vertically downward under the limiting action of the limiting rod 27.

[0027] The top of the connecting plate 25 is fixedly connected to the second motor 28, the outer surface of the second motor 28 is fixedly connected to the protective shell 33, the other end of the output shaft of the second motor 28 is fixedly sleeved with the third rotating shaft 29, the bottom end of the third rotating shaft 29 passes through the connecting plate 25 and extends to the outside of the connecting plate 25 and is fixedly sleeved with the rotating rod 30, and the left and right sides of the rotating rod 30 are both hinged with connecting rods 31.

[0028] When the second motor 28 starts running, it will drive the third rotating shaft 29 to rotate the rotating rod 30 synchronously, thereby causing the two connecting rods 31 to move.

[0029] The other end of the connecting rod 31 is hinged to a clamping plate 32, and the bottom end of the connecting plate 25 is fixedly connected to a C-shaped frame 34. The outer surface of the clamping plate 32 is movably connected to the inner surface of the C-shaped frame 34.

[0030] When the connecting rod 31 moves, the clamping plate 32 will move horizontally under the limiting action of the C-shaped frame 34.

[0031] Working principle and usage process of this utility model: First, place the monocrystalline silicon rod to be degummed between two clamping plates 32, and start the second motor 28 to drive the third rotating shaft 29 to rotate the rotating rod 30 synchronously, thereby causing the two connecting rods 31 to move. Then, under the limiting action of the C-shaped frame 34, the two clamping plates 32 move horizontally towards each other. Finally, the two clamping plates 32 achieve the fixing effect of monocrystalline silicon rods of different sizes, improving the applicability of the device. Then, start the first motor 23 to rotate the threaded rod 24. At this time, the connecting plate 25 will drive the clamping plates 32 and the monocrystalline silicon rod to move downward under the limiting action of the limiting rod 27, and finally enter the inner cavity of the degumming box 1.

[0032] Then, the liquid pump connected to the mounting pipe 11 is turned on, and the high-temperature descaling chemical solution is sent into the interior of the distributor 7 through the mounting pipe 11, the distributor pipe 10, the second pipe 9, and the first pipe 8. This allows multiple nozzles 35 to thermally spray the monocrystalline silicon rod that has moved down between the first descaling brush roller 16 and the second descaling brush roller 20. Simultaneously, the drive motor 2 is started, causing the first rotating shaft 3 to rotate the cam 4. At this time, the cam 4 presses against the movable plate 5, causing the movable plate 5 to drive the round rod 6 to move horizontally under the limiting action of the descaling box 1, thereby allowing the distributor 7 to... Pipe 8 moves horizontally to the left within the cavity of pipe 9. When the cam 4 rotates more than 90 degrees, the stainless steel spring 12, which is in a stretched state, pulls the movable plate 5 back to its original position. This allows the spray nozzle 35 to be adjusted horizontally during spraying, ensuring that the monocrystalline silicon rod is evenly and synchronously covered by the high-speed fresh liquid, effectively eliminating cleaning dead corners and ensuring the desmearing effect and quality. Finally, the power motor 14 is started, causing the first desmearing brush roller 16 and the second desmearing brush roller 20 to rotate synchronously in opposite directions, performing roller brush desmearing on the monocrystalline silicon rod.
