Description

A crystal delivery device Technical Field

[0001] This utility model belongs to the field of crystal transport technology, specifically a crystal transport device. Background Technology

[0002] Single-crystal silicon usually refers to a substance in which silicon atoms are arranged in a certain form. In the specific process of crystal processing, it is necessary to transfer the molten crystal material from the melting process to the crystal pulling process. In order to ensure its smooth transfer between different processing stages, a crystal transport device is required.

[0003] Existing crystal conveying devices are used to efficiently and stably transport crystal materials in industrial production. The devices use synchronous belt conveyors for transporting crystal resonator supports. The device includes a base, a synchronous belt, and a motor. The synchronous belt is driven by a synchronous pulley, which moves the support along the base track. This device has a high degree of automation and high speed, which changes the traditional manual conveying method and improves production efficiency.

[0004] However, existing devices still have some problems. In the specific process of crystal processing, the molten crystal material needs to be transferred from the melting process to the crystal pulling process. Therefore, the conveyor belt needs to circulate in the processing workshop. During the transfer, the surface of the conveyor belt may adhere to the crystal surface. It is also necessary to prevent the debris from the surface of the molten crystal from falling onto the surface of the conveyor belt. If the debris reacts chemically with different types of crystals, it can easily affect the subsequent processing of the crystal, thus reducing the quality of crystal transport. Therefore, a crystal transport device is proposed to address the above problems. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a crystal transport device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a crystal conveying device, including: a support frame, a hollow arc-shaped plate installed on one side of the support frame, a nozzle installed on one side of the hollow arc-shaped plate, a gas supply pipe installed on one side of the hollow arc-shaped plate, a gas box connected to one end of the gas supply pipe, a vacuum pump installed on the upper surface of the gas box and connected to the gas supply pipe, a connecting pipe installed on one side of the gas box, a control valve installed on the connecting pipe, a collection box installed on the support leg of the support frame, an exhaust hole opened at the bottom of the collection box, an adsorbent sponge placed inside the collection box, the collection box facing the nozzle, and the dust-free gas in the gas box is drawn into the gas supply pipe and the hollow arc-shaped plate by the vacuum pump, and then blown out through the nozzle, which can blow off the crystal residue on the surface of the internal toothed conveyor belt.

[0007] Preferably, a drive motor is installed on one side of the support frame, and the output end of the drive motor is fixedly connected to a main tooth transmission shaft. One end of the main tooth transmission shaft is rotatably connected inside the support frame. One end of the main tooth transmission shaft is located inside the support frame, and the other end is connected to the drive motor, thereby improving the stability of the conveying device operation.

[0008] Preferably, the outer surface of the main tooth transmission shaft is connected to an inner tooth transmission belt, the outer surface of the inner tooth transmission belt is equipped with a frustum, and the inner surface of the inner tooth transmission belt is connected to four sets of auxiliary tooth transmission shafts. Both ends of the four sets of auxiliary tooth transmission shafts are rotatably connected to the inside of the support frame, and both ends of the four sets of auxiliary tooth transmission shafts are located inside the support frame, thereby ensuring the stability of crystal transport.

[0009] Preferably, a connecting plate is installed on the outer surface of the internal toothed conveyor belt, an electronic pressure gauge is installed on the upper surface of the connecting plate, an electric telescopic rod is installed on one side of the connecting plate, and a fixing plate is installed at the telescopic end of the electric telescopic rod. When the electric telescopic rod is operated, the position of the fixing plate can be adjusted, thereby fixing the crystal.

[0010] Preferably, an airbag is installed on one side of the fixing plate, a silicone pad is connected to one side of the airbag, a connecting wire is connected inside the airbag and connected to an electronic pressure gauge, a PLC controller is installed on one side of the support frame, and the silicone pad contacts the crystal surface to reduce contact stress and avoid scratching the crystal surface.

[0011] Preferably, the PLC controller is used to control the start and stop of the nozzle, vacuum pump, drive motor, electronic pressure gauge and electric telescopic rod, and the PLC controller is used to process the data of the electronic pressure gauge. By controlling the nozzle, vacuum pump, drive motor, electronic pressure gauge and electric telescopic rod through the PLC controller, the ease of use of the device is improved.

[0012] The advantages of this invention are as follows: By blowing clean gas onto the surface of the internal toothed conveyor belt through the nozzle, the residue on the surface of the internal toothed conveyor belt and the frustum can be carried into the collection box by the blowing of clean gas. The adsorption sponge can adsorb the residue, and in conjunction with the exhaust hole, it reduces the possibility of the residue spreading outward again due to the wind force. This improves the cleanliness of the internal toothed conveyor belt and the frustum during the crystal transport process, and avoids the chemical reaction between the debris on the surface of the melted crystal and different types of crystals, thereby improving the quality of crystal transport.

[0013] This invention uses a crystal and a fixing plate to compress an airbag. The pressure value of the airbag is transmitted to an electronic pressure gauge, and the PLC controller analyzes the pressure value. When the pressure value exceeds a set value, the crystal is fixed and the compression of the crystal stops. This avoids damage to the crystal due to excessive pressure and prevents movement of the crystal during transport due to insufficient clamping pressure. It improves the accuracy of crystal fixing and avoids vibrations generated by the device during crystal transport. The lack of a positioning mechanism can cause multiple crystals to shift and collide, leading to crystal aggregation. This reduces the time required for manual crystal position adjustment during crystal transport, thereby improving crystal transport efficiency. Attached Figure Description

[0021] 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 scope of protection of the present utility model.

[0022] Please refer to Figures 1-5. A crystal delivery device includes: a support frame 1, a hollow arc plate 2 installed on one side of the support frame 1, a nozzle 3 installed on one side of the hollow arc plate 2, a gas supply pipe 4 installed on one side of the hollow arc plate 2, a gas box 5 connected to one end of the gas supply pipe 4, a vacuum pump 6 installed on the upper surface of the gas box 5 and connected to the gas supply pipe 4, a connecting pipe installed on one side of the gas box 5, a control valve installed on the connecting pipe, a collection box 7 installed on the support leg of the support frame 1, an exhaust hole opened at the bottom of the collection box 7, an adsorption sponge 8 placed inside the collection box 7, and the collection box 7 facing the nozzle 3.

[0023] In the specific process of crystal processing, molten crystal material needs to be transferred from the melting process to the crystal pulling process. Therefore, a conveyor belt needs to circulate in the processing workshop. During the transport process, crystal surfaces may adhere to the conveyor belt surface. It is important to prevent crystal debris from falling onto the conveyor belt surface. If this debris reacts chemically with different types of crystals, it can easily affect subsequent crystal processing. Therefore, a crystal conveying device is proposed. In actual use, a connecting pipe is connected to an external clean gas transmission pipe, allowing clean gas to enter the gas chamber 5. Then, a vacuum pump 6 and nozzle 3 are activated via an external control box, drawing the gas from the gas chamber 5 into the gas delivery pipe 4 and the hollow arc-shaped plate 2. The clean gas is then distributed through the nozzle 3. The nozzle 3 sprays air onto the surfaces of the internal toothed conveyor belt 11 and the frustum 111. The dust-free gas blows away the residue on the surfaces of the internal toothed conveyor belt 11 and the frustum 111. Since the blowing direction of the nozzle 3 is opposite to that of the collection box 7, the blown-off residue is carried by the airflow to the surface of the adsorption sponge 8. The gas is discharged outward through the exhaust hole at the bottom of the collection box 7, thus completing the cleaning of the surfaces of the internal toothed conveyor belt 11 and the frustum 111. The adsorption sponge 8 can adsorb the residue, and in conjunction with the exhaust hole, it reduces the possibility of the residue spreading outward again due to the wind force. This improves the cleanliness of the internal toothed conveyor belt 11 and the frustum 111 during the crystal transport process and avoids chemical reactions between the debris on the surface of the melted crystal and subsequent crystals of different types.

[0024] Please refer to Figures 1-5. A drive motor 9 is installed on one side of the support frame 1. The output end of the drive motor 9 is fixedly connected to a main tooth transmission shaft 10. One end of the main tooth transmission shaft 10 is rotatably connected to the inside of the support frame 1. An internal tooth transmission belt 11 is driven to the outer surface of the main tooth transmission shaft 10. A frustum 111 is installed on the outer surface of the internal tooth transmission belt 11. Four sets of auxiliary tooth transmission shafts 12 are driven to the inner surface of the internal tooth transmission belt 11. Both ends of the four sets of auxiliary tooth transmission shafts 12 are rotatably connected to the inside of the support frame 1. A connecting plate 13 is installed on the outer surface of the internal tooth transmission belt 11. A connecting plate 13 is installed on the upper surface of the connecting plate 13. An electronic pressure gauge 14 is provided. An electric telescopic rod 15 is installed on one side of the connecting plate 13. A fixing plate 16 is installed on the telescopic end of the electric telescopic rod 15. An airbag 17 is installed on one side of the fixing plate 16. A silicone pad 18 is connected to one side of the airbag 17. A connecting wire 19 is connected inside the airbag 17. The connecting wire 19 is connected to the electronic pressure gauge 14. A PLC controller 20 is installed on one side of the support frame 1. The PLC controller 20 is used to control the start and stop of the nozzle 3, vacuum pump 6, drive motor 9, electronic pressure gauge 14 and electric telescopic rod 15. The PLC controller 20 is also used to process the data of the electronic pressure gauge 14.

[0025] The crystal is placed on the surface of the frustum 111. The PLC controller 20 activates the electric telescopic rods 15 on both sides of the crystal, pushing the two sets of fixing plates 16 towards the center, reducing the distance between the two sets of silicone pads 18. This causes the silicone pads 18 to adhere to the crystal surface, and the crystal and fixing plates 16 compress the airbag 17. The pressure value inside the airbag 17 is transmitted to the electronic pressure gauge 14 via the connecting line 19, allowing for pressure monitoring. The PLC controller 20 analyzes the pressure value of the airbag 17. When the pressure value exceeds the value set in the PLC controller 20, the electric telescopic rods 15 are deactivated, thus fixing the crystal and stopping the compression. This prevents damage to the crystal due to excessive pressure and avoids movement during transport due to insufficient clamping pressure. This improves the precision of crystal fixation and avoids vibrations generated during crystal transport. The lack of a positioning mechanism can cause multiple crystals to shift and collide, leading to crystal aggregation. This reduces the time spent manually adjusting crystal positions during transport, thus improving transport efficiency. The PLC controller 20 starts the drive motor 9, which rotates the main toothed transmission shaft 10, thereby driving the internal toothed transmission belt 11. This, in turn, drives the four sets of auxiliary toothed transmission shafts 12, transferring the molten crystal material from the melting process to the crystal pulling process. After the crystal is transported to the designated position by the internal toothed transmission belt 11, the PLC controller 20 starts the electric telescopic rod 15, pulling the fixing plates 16 on both sides outwards, thus releasing the crystal from the internal toothed transmission belt 11 for crystal pulling.

[0026] Working principle: The crystal is placed on the frustum 111. The PLC controller 20 activates the electric telescopic rods 15 on both sides of the crystal, pushing the two sets of fixing plates 16 towards the center, causing the silicone pad 18 to contact the crystal surface. The crystal and fixing plates 16 compress the airbag 17. The pressure value inside the airbag 17 is transmitted to the electronic pressure gauge 14 via the connecting line 19, allowing for pressure detection. The PLC controller 20 analyzes the pressure value of the airbag 17. When the pressure value exceeds the value set in the PLC controller 20, the electric telescopic rods 15 are closed, thus fixing the crystal and stopping the compression. The PLC controller 20 then activates the drive motor 9, driving the main toothed transmission shaft 10 to rotate, which in turn drives the internal toothed transmission belt 11, which in turn drives the four sets of auxiliary toothed transmission shafts 12 to rotate, thus transporting the crystal. The crystal is transported by the internal toothed transmission belt. After the crystal is transported to the crystal pulling equipment via conveyor belt 11, the electric telescopic rod 15 is activated by the PLC controller 20 to pull the fixing plates 16 on both sides outward, thereby releasing the crystal from the fixing and allowing the crystal to be removed from the internal toothed conveyor belt 11 for crystal pulling. When the internal toothed conveyor belt 11 is in motion, the connecting pipe is connected to the external dust-free gas transmission pipe, allowing dust-free gas to enter the interior of the gas box 5. Subsequently, the vacuum pump 6 and nozzle 3 are activated by the external control box, thereby drawing the gas in the gas box 5 into the gas supply pipe 4 and the interior of the hollow arc plate 2. The dust-free gas is sprayed onto the surface of the internal toothed conveyor belt 11 and the frustum 111 through the nozzle 3. The dust-free gas blows off the residue on the surface of the internal toothed conveyor belt 11 and the frustum 111, thereby improving the cleanliness of the internal toothed conveyor belt 11 and the frustum 111 during the crystal transport process and preventing the debris on the surface of the melted crystal from reacting chemically with subsequent crystals of different types.
