Description
Technical Field
[0001] The utility model belongs to the technical field of photovoltaic equipment, and in particular relates to a silicon material re-feeding box. Background Art
[0002] At present, in the process of supplying raw materials to single crystal furnaces, it is necessary to manually break the raw material bags and pour them into the barrel, which is inefficient, labor-intensive, and in a bad environment, and can cause occupational diseases (silicosis) to workers. In order to improve the level of factory automation and informatization, reduce labor intensity, and improve work efficiency, it is very necessary to design and develop automatic feeding equipment for repeated feeding, achieve staff reduction, reduce labor intensity, and achieve the construction of a smart factory with fewer people, automation, and informatization.
[0003] Through the above analysis, the problems and defects of the prior art are as follows:
[0004] The existing process of supplying raw materials to single crystal furnaces relies on manual breaking of raw material bags and pouring them into barrels. This is inefficient, labor-intensive, and has a harsh environment, and can also cause workers to suffer from an occupational disease, silicosis. Utility Model Content
[0005] In view of the problems existing in the prior art, the utility model provides a silicon material re-feeding box.
[0006] The utility model is implemented in this way. A silicon material re-feeding box comprises: a box body, a silicon material re-feeding box reinforcement ribs, a polyurethane wear-resistant layer, and a high-frequency label; a polyurethane wear-resistant layer is arranged on the top of the box body, a high-frequency label is arranged on the bottom, and a silicon material re-feeding box reinforcement ribs are arranged inside.
[0007] Furthermore, the material box body is integrally cast with polyurethane material, and the inner corners are rounded.
[0008] Furthermore, the polyurethane wear-resistant layer is fixed to the top of the material box body by bolts and can be removed and replaced.
[0009] Furthermore, high frequency tags can be identified by RFID.
[0010] Furthermore, a gripping point for a mechanical gripper is provided on the reinforcing ribs of the silicon material re-feeding box.
[0011] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the utility model are as follows:
[0012] First, the utility model solves the problem that the current photovoltaic industry still needs to manually break the raw material bags and pour them into the barrel when supplying raw materials to the single crystal furnace. This is inefficient, labor-intensive, and in a harsh environment. It can also cause occupational diseases to workers, such as silicosis, and high labor costs. The built-in metal reinforcements improve the strength of the material box and reduce its own weight. The rounded corners reduce silicon material blockage. The use of high-hardness polyurethane increases the wear resistance of the material box and thus increases its service life. Each material box is equipped with a high-frequency tag to give each material box its identity information, which is used to bind the information of the material box with the raw material, avoiding the risk of the entire silicon rod being scrapped due to the wrong raw material. When applied to the factory production process, it can achieve the effect of streamlining personnel and reducing labor intensity, which is of great significance to the construction of a less-manned, automated, and information-based smart factory.
[0013] Secondly, the utility model is integrally cast with polyurethane material, which reduces the weight of the material box itself, uses high-hardness polyurethane to reduce the friction coefficient between the silicon material and the material box, and rounds the internal corners to reduce silicon material clogging.
[0014] The utility model strengthens the overall strength of the material box and the gripping strength of the hand claw by pouring polyurethane after fixing the reinforcing ribs.
[0015] The utility model uses the port bolts to fix the polyurethane wear-resistant layer, which can prevent the material box port from being worn and can replace the wear-resistant layer.
[0016] The utility model adds a high-frequency mark on the bottom of the material box, and can use RFID to identify the material box, which is used to bind the information of the material box and the raw materials, thereby avoiding the risk of the entire silicon rod being scrapped due to adding the wrong raw materials.
[0017] Third, the expected benefits and commercial value of the technical solution of the utility model after transformation are as follows: each material box is equipped with a high-frequency tag to give each material box its identity information, which is used to bind the information of the material box with the raw material, avoiding the risk of the entire silicon rod being scrapped due to adding the wrong raw material. In 2022, my country's photovoltaic monocrystalline silicon production will reach 357GW. According to statistics, one silicon rod will be scrapped and reworked every year for every 1GW due to adding the wrong raw material and other reasons. Calculated at a price of 300,000 per silicon rod, it can reduce the losses of photovoltaic companies by 107 million each year. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0023] The silicon material re-feeding box provided by the embodiment of the utility model comprises: a box body 1, a silicon material re-feeding box reinforcement rib 2, a polyurethane wear-resistant layer 3, and a high-frequency label 4; the box body 1 is provided with a polyurethane wear-resistant layer 3 on the top, a high-frequency label 4 on the bottom, and a silicon material re-feeding box reinforcement rib 2 inside.
[0024] like Figure 1 As shown, the material box body 1 is integrally cast with polyurethane material, which reduces the weight of the material box itself, uses high-hardness polyurethane to reduce the friction coefficient between the silicon material and the material box, and rounds the internal corners to reduce clogging of the silicon material; the polyurethane wear-resistant layer 3 is fixed to the top of the material box body 1 with bolts, which can protect the material box body 1 and prevent wear on the material box mouth, and the polyurethane wear-resistant layer 3 is replaceable.
[0025] like Figure 2 As shown, the reinforcing ribs 2 of the silicon material re-feeding box are arranged inside the box body 1, which can strengthen the force of the overall frame and provide a gripping point for the robot; the high-frequency tag 4 is arranged at the bottom of the box body 1, and the silicon material re-feeding box can be identified by RFID.
[0026] like Figure 3 The figure is a schematic diagram of the reinforcing ribs of the silicon material re-feeding box provided in an embodiment of the utility model.
[0027] The structural principle of the utility model:
[0028] The silicon material re-feeding box provided by the utility model comprises: a box body 1, a reinforcing rib 2, a polyurethane wear-resistant layer 3, and a high-frequency tag 4. It is integrally cast with polyurethane material, which reduces the weight of the box itself. High-hardness polyurethane is used to reduce the friction coefficient between the silicon material and the box, and the internal corners are rounded to reduce the blockage of silicon material. After fixing the reinforcing rib, polyurethane is cast to strengthen the overall strength of the box and the gripping strength of the gripper. The polyurethane wear-resistant layer 3 is fixed by bolts at the port to prevent wear of the box mouth and can be replaced. A high-frequency tag is installed at the bottom of the box, and the box is identified by RFID.
[0029] The utility model is a reliable structure invented for silicon material re-feeding through long-term research on artificial bag breaking to pour materials into the barrel, which can improve the automation and information level of the factory, reduce labor intensity and improve work efficiency.
[0030] The technical solution of this utility model adopts a large number of ANSYS finite element analysis to ensure that the equipment can meet the design requirements. The following is a finite element analysis of the deformation of the material box body when it is full of 80KG of raw materials and is grabbed by the clamp. The finite element analysis shows that the deformation of the material box body when it is full of 80KG of raw materials and is grabbed by the clamp reaches 5mm, which does not meet the design requirements. Therefore, the material box body is reinforced and reinforcing ribs are embedded in the polyurethane. Figure 3 , meeting the design requirement of deformation not exceeding 1.5mm.
[0031] The silicon material re-feeding box provided in the embodiment of the utility model mainly comprises the following parts:
[0032] The material box body 1 is integrally cast from polyurethane material, which is light and high-strength, greatly reducing the weight of the material box itself. At the same time, its high hardness can reduce the friction coefficient between the silicon material and the material box, preventing the silicon material from being blocked during transportation or use. A through hole is set at the top of the material box body 1 to facilitate the delivery of silicon material and the grabbing of the robot.
[0033] Silicon material re-feeding box reinforcement rib 2: This is a reinforcement device set inside the box body 1, which is used to increase the strength and stability of the box to prevent the box from deformation or breakage during transportation and use. At the same time, the design of the reinforcement rib also facilitates the gripping of the robot, increasing the convenience and safety of operation.
[0034] Polyurethane wear-resistant layer 3: This is a wear-resistant material fixed to the top of the material box body 1 by bolts, which can effectively protect the material box body 1 from wear and tear and extend the service life of the material box. When the silicon material re-feeding box is put in, the wear-resistant layer first contacts the feeding port, reducing the wear on the material box body. At the same time, the wear-resistant layer can be replaced, which is convenient for maintenance and replacement.
[0035] High frequency tag 4: The RFID tag set at the bottom of the material box body 1 can identify the silicon material re-feeding box by wireless induction. Through the corresponding reading and writing equipment, the information of the silicon material re-feeding box can be easily obtained and tracked, which greatly improves the management efficiency of the silicon material re-feeding box.
[0036] During specific use, the staff can read the information in the high-frequency tag 4 through the reading and writing equipment to understand the relevant data of the silicon material re-feeding box (such as production date, type, usage status, etc.). When the silicon material re-feeding box needs to be put in, the operator can grab the reinforcing rib 2 through the manipulator for delivery. During the whole process, the polyurethane wear-resistant layer 3 will protect the material box body 1 and reduce wear. At the same time, RFID technology allows each silicon material re-feeding box to be identified and tracked, greatly improving work efficiency and accuracy.
[0037] The silicon material re-feeding box provided by the embodiment of the utility model has the following advantages:
[0038] The material box body 1 is integrally cast from polyurethane material, which reduces the weight of the material box itself. At the same time, the high-hardness polyurethane can reduce the friction coefficient between the silicon material and the material box. Chamfering the internal corners can also effectively reduce the blockage of the silicon material.
[0039] The polyurethane wear-resistant layer 3 is fixed to the top of the material box body 1 by bolts, which can protect the material box body 1 and prevent the wear of the material box mouth. The polyurethane wear-resistant layer 3 can also be replaced, which increases the service life of the material box and facilitates maintenance.
[0040] The reinforcing ribs 2 of the silicon material re-feeding box are arranged inside the box body 1, which can enhance the force-bearing capacity of the overall frame and provide gripping points for the robot to grip, thereby improving the stability of the box and the stability of the robot to grip.
[0041] The high frequency tag 4 is arranged at the bottom of the material box body 1, and the silicon material re-feeding box can be identified by RFID technology, so as to facilitate the management and tracking of the silicon material re-feeding box.
