Description

Technical Field

[0001] This utility model relates to the field of single crystal silicon processing technology, specifically to a single crystal silicon rod coating device. Background Technology

[0002] With the continuous growth of global demand for clean energy, the photovoltaic industry is developing rapidly. Large-size silicon wafers have become an inevitable trend in silicon wafer development because they can significantly reduce the initial investment cost and cost per kilowatt-hour of photovoltaic power plants. This requires continuous improvement in the production efficiency and quality of monocrystalline silicon rods. As an important process in silicon rod production, coating requires more advanced coating equipment to meet the needs of large-size and high-precision coating. The semiconductor industry has extremely high requirements for the purity, dimensional accuracy, and surface quality of monocrystalline silicon rods.

[0003] An existing monocrystalline silicon rod coating device suffers from several drawbacks during operation. Firstly, it exhibits low coating precision: traditional coating methods, such as manual coating or simple mechanical coating equipment, struggle to accurately control the amount and location of adhesive. Secondly, it suffers from low production efficiency: manual coating requires extensive manual operation, is cumbersome, and slow, failing to meet the needs of large-scale production. Furthermore, it results in significant adhesive waste: some traditional coating methods cannot accurately control the amount of adhesive, easily leading to overflow or excessive use. This not only wastes adhesive but also contaminates the silicon rod surface and production equipment, increasing production and cleaning costs. A new monocrystalline silicon rod coating device addresses these issues. Utility Model Content

The third protective box is provided with a third motor 13. The output end of the third motor 13 is provided with a rotating shaft 14. The top of the rotating shaft 14 is provided with a turntable 15. The turntable 15 has a first sliding groove inside, and a clamping plate 16 is engaged in the first sliding groove.

[0028] Specifically, the controller 31 can be an existing controller on the market, such as a Siemens S7-300 PLC controller or a programmable single-chip microcomputer controller. According to the initial intention and purpose of the implementation of the device, the controller 31 is programmed so that the controller 31 can control the working status of the first motor 3, the second motor 9, the third motor 13, the control valve, the camera 19 and the distance sensor 20, so as to cooperate with each other to complete the corresponding control and operation in accordance with the implementation spirit of the scheme.

[0029] Please refer to Figure 1 to Figure 2 The right inner wall of the first protective box 2 is provided with a first guide rod 17, the first slider 5 is sleeved on the outer surface of the first guide rod 17, the inside of the first slider 5 is provided with a second sliding groove, and the second slider 7 is engaged in the second sliding groove.

[0030] Specifically, the first guide rod 17 limits the first slider 5, allowing the first slider 5 to move left and right along the direction of the first guide rod 17, and the second slide groove limits the second slider 7, allowing the second slider 7 to move up and down under the push or pull of the electric telescopic rod 6.

[0031] Please see Figures 4 to 5 The second protective box 8 has a second guide rod 18 on its front inner side wall, and a third slider 11 is sleeved on the outer surface of the second guide rod 18.

[0032] Specifically, the second guide rod 18 limits the movement of the third slider 11, allowing the third slider 11 to move back and forth along the direction of the second guide rod 18.

[0033] Please see Figures 6 to 7The bottom of the third slider 11 is equipped with a camera 19 and a distance sensor 20. The outer surface of the glue gun 12 is equipped with a connecting tube, and the other end of the connecting tube is fitted with a flexible tube. The inside of the glue gun 12 is equipped with a control valve.

[0034] Specifically, the camera 19 and the distance sensor 20 provide information to the controller 31 to determine the height and diameter of the monocrystalline silicon rod in order to adjust the position of the glue gun 12.

[0035] Please refer to Figure 4 to Figure 5 The inner wall of the turntable 15 is provided with a support rod 21, and a first spring 22 is sleeved on the outer surface of the support rod 21. A first baffle 30 is provided on one side of the clamping plate 16, and the clamping plate 16 is sleeved on the outer surface of the support rod 21.

[0036] Specifically, the support rod 21 limits the clamping plate 16, allowing the clamping plate 16 to slide in the first groove inside the turntable 15 and compress the first spring 22.

[0037] Please see Figures 2 to 3 The workbench 1 has a collection trough inside, and a collection box 23 is provided at the bottom of the workbench 1. A third sliding groove is provided inside the rear wall of the collection box 23. A filter plate 24 is engaged in the third sliding groove, and a filter screen 25 is embedded inside the filter plate 24.

[0038] Specifically, the overflowing glue is collected in the collection tank 23 through the collection trough, so that the collection tank 23 can recycle the overflowing glue, and the filter screen 25 can filter the glue.

[0039] Please refer to Figure 2 to Figure 3 A card box 26 is provided on the left side of the collection box 23. A first through hole is opened inside the left wall of the card box 26. A pull rod 27 adapted to the inner diameter of the first through hole is provided in the first through hole. A second spring 28 is sleeved on the outer surface of the pull rod 27. A second baffle 29 is welded to the outer surface of the pull rod 27. A second through hole is opened inside one end of the filter plate 24. The inner diameter of the second through hole is slightly larger than the diameter of the pull rod 27.

[0040] Specifically, when cleaning the filter screen 25, pull the lever 27, which in turn moves the second baffle 29 and squeezes the second spring 28. The lever 27 disengages from the second through hole inside one end of the filter plate 24, no longer limiting the filter plate 24, and removes the filter plate 24 from the collection box 23 to clean the filter screen 25.

[0041] During use, when applying adhesive to the monocrystalline silicon rod, the height of the adhesive application gun 12 is first adjusted according to the length of the monocrystalline silicon rod. While adjusting the height of the adhesive application gun 12, the electric telescopic rod 6 is activated by the controller 31. The movable end of the electric telescopic rod 6 extends or retracts to adjust the height of the second slider 7 and the second protective box 8, thereby adjusting the height position of the adhesive application gun 12. After the height of the adhesive application gun 12 is adjusted, the monocrystalline silicon rod is placed on the turntable 15. During the placement process, when the outer surface of the monocrystalline silicon rod abuts against the clamping plate 16 and moves downward, the monocrystalline silicon rod exerts a pushing force on the clamping plate 16, causing the clamping plate 16 to move along the support rod 21 and squeeze the first spring 22 until the monocrystalline silicon rod is placed on the turntable 15, at which point the clamping plate 16 stops moving. The three clamping plates 16 then apply pressure to the monocrystalline silicon rod. After the monocrystalline silicon rod is placed on the turntable 15, the controller 31 starts the first motor 3, the second motor 9, and the third motor 13. The output of the first motor 3 drives the first lead screw 4 to rotate. The first lead screw 4 drives the first slider 5, which is connected to the outer surface of the first lead screw 4. This causes the first slider 5 to move the second slider 7, the second protective box 8, the third slider 11, and the glue gun 12 left and right. The second motor 9 drives the second lead screw 10 to rotate. The second lead screw 10 drives the third slider 11, which is connected to the outer surface of the second lead screw 10. This causes the third slider 11 to move the glue gun 12 back and forth. According to the different specifications of the monocrystalline silicon rod and the requirements of the glue pattern, with the cooperation of the camera 19 and the distance sensor 20, the movement is precisely controlled. The glue application position is precisely controlled, greatly improving the glue application accuracy. During the glue application process (taking left-to-right application as an example), after the glue gun 12 completes the glue application for one single-crystal silicon rod, the output end of the second motor 9 drives the second lead screw 10 to rotate. The second lead screw 10 drives the third slider 11 and the glue gun 12 to move backward until the glue gun 12 moves above the collection tank. The glue overflowing from the glue gun 12 drips into the collection tank. The first motor 3 then drives the first lead screw 4 to rotate. The first lead screw 4 drives the first slider 5, the second slider 7, the second protective box 8, and the glue gun 12, which are connected to the outer surface of the first lead screw 4, to move until the glue gun 12 moves to the axis position of the next turntable 15. Then, the output end of the second motor 9 rotates in the opposite direction, driving the second lead screw 10. Motor 10 drives the third slider 11 and the glue gun 12 until the glue gun 12 moves above the next monocrystalline silicon rod. After moving above the next monocrystalline silicon rod, the speed of the second motor 9 decreases, the moving speed of the glue gun 12 slows down, and the control valve opens. Glue is sprayed from the glue gun 12 and falls onto the top of the monocrystalline silicon rod. The output of the third motor 13 drives the rotating shaft 14, turntable 15, clamping plate 16, and monocrystalline silicon rod to rotate, ensuring uniform glue application. After the monocrystalline silicon rod is coated, the above operation is repeated. The overflowing glue drips into the collection tank and, after being filtered by the filter screen 25, finally collects in the collection box 23. To prevent the glue from solidifying and clogging the filter screen 25, the filter screen 25 needs to be cleaned in time. When cleaning the filter screen 25, the lever 27 is pulled.Pull rod 27 moves the second baffle 29, which in turn compresses the second spring 28. Pull rod 27 disengages from the second through hole inside one end of filter plate 24, no longer limiting the filter plate 24, allowing it to be removed from the collection box 23 for cleaning of the filter screen 25.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
