Description

Technical Field

[0001] This utility model relates to the field of photovoltaic manufacturing technology, specifically to a quartz cylinder transport vehicle for monocrystalline silicon production. Background Technology

[0002] In the photovoltaic industry, the monocrystalline furnace is a crucial piece of equipment in the monocrystalline silicon production process. It undertakes the key task of converting polycrystalline silicon raw materials into monocrystalline silicon rods, and its operating efficiency and stability play a decisive role in the entire production process.

[0003] In the process of producing monocrystalline silicon rods in a monocrystalline furnace, a secondary feeding operation is required to meet the needs of continuous production. Specifically, workers need to fill the polycrystalline silicon raw material into a specially made quartz tube in the preparation room. Then, according to the production instructions, a tractor or AGV trolley precisely transports the fully loaded quartz tube to the corresponding monocrystalline furnace. After arriving at the designated furnace, the quartz tube is aligned with the furnace's auxiliary chamber, ensuring a secure connection. Then, the furnace activates its lifting device to slowly lift the quartz tube into the auxiliary chamber, thus completing the feeding operation. After feeding, the quartz tube descends under gravity and returns to the original position of the quartz tube transport vehicle. During the descent, the quartz tube often sways, requiring timely manual intervention. One hand firmly holds the quartz tube to prevent excessive shaking that could damage it or affect subsequent operations, while the other hand quickly fastens the straps to ensure the stability of the quartz tube during transportation.

[0004] During the feeding process, the straps need to be untied manually and the tilted quartz cylinder needs to be manually straightened. After the material in the first quartz cylinder is emptied, the connection needs to be disconnected, and then the vehicle needs to be manually moved to connect the second quartz cylinder to the auxiliary chamber. The operation of the first cylinder is repeated. This not only consumes a lot of manpower, but also easily leads to worker fatigue, which in turn affects the accuracy and efficiency of operation.

[0005] Therefore, in order to address the above problems, the applicant needs to design a quartz cylinder transport vehicle for monocrystalline silicon production to solve the problem. Utility Model Content

[0006] The purpose of this invention is to provide a quartz cylinder transport vehicle for monocrystalline silicon production, in order to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quartz cylinder transport vehicle for monocrystalline silicon production, including an AGV trolley, and the AGV trolley is equipped with a stabilizing frame.

[0008] It also includes: a control mechanism mounted on the AGV trolley, which is used to move the quartz tube. The control mechanism includes a fixed frame slidably connected to the stabilizing frame, and a connector is fixedly mounted on the fixed frame. An electric cylinder is hinged to the connector, and the output end of the electric cylinder is hinged to the fixed component. A bearing component is mounted on the fixed component, which is used to place the quartz tube. A second connector is fixedly mounted on the fixed frame, and an electric cylinder is hinged to the second connector. The end of the electric cylinder away from the second connector is hinged to the fixed component. A support frame is fixedly mounted below the fixed component, and the support frame is fixedly connected to the stabilizing frame.

[0009] Furthermore, the bearing assembly includes a linkage frame fixedly connected to a fixing member, and at least two supports are fixedly installed on the linkage frame. Each of the two supports is fixedly installed with a bearing plate, and a quartz cylinder body is placed on the bearing plate.

[0010] The above structural design enables automated carrying and transportation of multiple quartz cylinders, effectively reducing manual handling and improving feeding efficiency.

[0011] Furthermore, a connecting frame is fixedly installed on the bracket, and a sliding rod is fixedly installed on the connecting frame. A fixing plate is rotatably installed on the sliding rod, and the fixing plate is fixedly connected to the fixing frame.

[0012] Through the above structural design, the rotational cooperation between the slide rod and the fixed plate provides stable guidance and auxiliary support for the lifting process, effectively preventing the quartz cylinder from tipping over during the lifting process.

[0013] Furthermore, the support plate is provided with guard rods arranged in a circumferential array, and the guard rods are located on the outside of the quartz cylinder body.

[0014] Through the above structural design, the guardrail forms a protective fence that can limit and protect the quartz cylinder during transportation and lifting, preventing it from being damaged by shaking.

[0015] Furthermore, the bracket is fixedly provided with a strap, and the strap is made of nylon cloth.

[0016] Through the above structural design, the use of pre-fixed nylon cloth straps eliminates the need for manual searching and binding, achieving rapid and automatic fastening of the quartz tube and saving operation time.

[0017] Furthermore, a fixed base is fixedly installed on the stabilizing frame, and an electrical control box is installed on the fixed base. The electrical control box is electrically connected to electric cylinder one, electric cylinder two, and the AGV trolley.

[0018] Through the above structural design, the electrical control box centrally controls all electric components, realizing the automated operation of the entire feeding process, reducing manual intervention and dependence on operators.

[0019] Furthermore, the support plate is provided with anti-slip grooves, and the anti-slip grooves are provided with an anti-slip coating.

[0020] Through the above structural design, the anti-slip groove and coating increase the friction between the bearing plate and the quartz cylinder, preventing the quartz cylinder from sliding and shifting during transportation.

[0021] Furthermore, the anti-slip coating is a silicone rubber coating.

[0022] Through the above structural design, the silicone rubber coating can provide a long-lasting and stable high coefficient of friction, ensuring that the quartz cylinder remains stable under various working conditions.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] When in use, this quartz cylinder transport vehicle for monocrystalline silicon production automatically transports and precisely positions the quartz cylinders, replacing manual pushing. The electric cylinder-driven control mechanism automatically completes the lifting, docking, lowering, and leveling of the quartz cylinders, eliminating the need for manual, laborious uprighting operations. At the same time, the guard rods and preset straps on its load-bearing components automatically suppress swaying and achieve rapid fastening, eliminating safety hazards and the tediousness of manual binding. The centralized electronic control system coordinates all actions, reducing the labor intensity, labor costs, and reliance on operational skills of workers, ultimately significantly improving the efficiency, accuracy, continuity, and inherent safety level of the feeding operation.

[0031] 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.

[0032] like Figures 1-5 As shown, this utility model discloses a quartz tube transport vehicle for monocrystalline silicon production, including an AGV trolley 1, on which a stabilizing frame 10 is provided, and a control mechanism 2 is provided on the AGV trolley 1, which is used to drive the quartz tube to move. The control mechanism 2 includes a fixed frame 20 slidably connected to the stabilizing frame 10, and a connector 21 is fixedly provided on the fixed frame 20. An electric cylinder 22 is hinged to the connector 21, and a fixing member 23 is hinged to the output end of the electric cylinder 22. A bearing component 24 is provided on the fixing member 23, and the bearing component 24 is used to place the quartz tube. A second connector 25 is fixedly provided on the fixed frame 20, and an electric cylinder 26 is hinged to the connector 25. A fixing member 27 is hinged to the end of the electric cylinder 26 away from the connector 25. A support frame 28 is fixedly provided below the fixing member 27, and the support frame 28 is fixedly connected to the stabilizing frame 10.

[0033] The supporting component 24 includes a linkage frame 240 fixedly connected to the fixing component 23, and at least two supports 241 are fixedly installed on the linkage frame 240. Each of the two supports 241 is fixedly installed with a supporting plate 242, and a quartz tube body 243 is placed on the supporting plate 242. Through the cooperative design of the linkage frame 240 and multiple supports 241, the supporting component 24 can stably support at least two quartz tubes at the same time, realize multi-station automated material preparation and transportation, reduce the need for manual handling and switching of quartz tubes multiple times, and improve the operation efficiency of continuous feeding of single crystal furnace.

[0034] A connecting frame 246 is fixedly mounted on the bracket 241, and a sliding rod 247 is fixedly mounted on the connecting frame 246. A fixing plate 248 is rotatably mounted on the sliding rod 247, and the fixing plate 248 is fixedly connected to the fixing frame 20. By setting up a rotation guide mechanism composed of the connecting frame 246, the sliding rod 247 and the fixing plate 248, precise radial constraint and auxiliary support are provided for the lifting and lowering movement of the entire bearing assembly 24 under the drive of the electric cylinder. This greatly enhances the rigidity and stability of the equipment during operation and effectively avoids the risk of swaying or overturning that may occur when the quartz cylinder is lifted or lowered due to inertia or center of gravity shift.

[0035] The support plate 242 is arranged with guard rods 245 in a circular array along its circumference. The guard rods 245 are located on the outside of the quartz tube body 243. The guard rods 245 arranged in a circular array around the support plate 242 form a rigid protective frame, which can stably restrict the quartz tube within the predetermined working area. This effectively resists external impacts and internal shaking during the movement, start-up, stop, or docking of the AGV trolley 1, providing reliable mechanical protection for the fragile quartz tube and reducing the probability of damage caused by impacts.

[0036] A strap 244 is fixedly installed on the bracket 241. The strap 244 is made of nylon cloth. The strap 244, made of high-strength nylon cloth, is pre-fixed to the bracket 241, forming a readily available quick fastening solution. During operation, there is no need for manual searching and laborious binding. The fastening or loosening of the quartz tube can be completed with simple operation, which greatly simplifies the operation process, saves time, and eliminates the problem of loose binding caused by human subjective factors.

[0037] A fixed base 11 is fixedly installed on the stabilizing frame 10, and an electrical control box 12 is installed on the fixed base 11. The electrical control box 12 is electrically connected to the electric cylinder 22, the electric cylinder 26 and the AGV trolley 1. The integrated electrical control box 12 concentrates all core functions such as the movement of the AGV trolley 1, the lifting action of the electric cylinder 22 and the leveling or locking action of the electric cylinder 26 in one place, realizing centralized programming and one-button automated control of the entire feeding process, reducing the labor intensity of operators, and improving the accuracy and coordination of system response.

[0038] The carrier plate 242 is provided with anti-slip grooves, and the anti-slip grooves are provided with an anti-slip coating. The anti-slip coating is a silicone rubber coating. The anti-slip grooves are processed on the surface of the carrier plate 242 and a special anti-slip coating is applied. The dual measures significantly increase the static friction coefficient between the carrier surface and the bottom of the quartz tube, ensuring that the quartz tube always stays in place when the transport vehicle accelerates, decelerates or crosses slightly uneven ground, eliminating the possibility of sliding and misalignment.

[0039] When using the quartz cylinder transport vehicle for monocrystalline silicon production, the AGV trolley 1, upon receiving an instruction, automatically travels to the designated monocrystalline furnace platform and precisely positions itself, aligning the quartz cylinder body 243 on the carrying assembly 24 with the furnace sub-chamber. Subsequently, the control mechanism 2 activates, and electric cylinder 26 adjusts the initial angle of the entire fixed frame 20 and the carrying assembly 24 to ensure perpendicularity to the sub-chamber. Then, electric cylinder 22 retracts, driving the carrying assembly 24 and its quartz cylinder body 243 smoothly upwards along the guide of the slide bar 247 via the linkage frame 240, precisely entering the furnace sub-chamber to complete the feeding. After feeding is complete, electric cylinder 22... The quartz cylinder body 243 is slowly extended, allowing it to descend smoothly to its original position on the transport vehicle. During this process, the circumferentially arranged guard rods 245 effectively suppress the swaying of the quartz cylinder body 243, and the pre-set nylon straps 244 can quickly complete the fastening without manual straightening or binding. When the material in one quartz cylinder body 243 is used up, the electric cylinder 22 can be activated again to lift the bearing component 24 to an appropriate height. The electric cylinder 26 is activated to align the second quartz cylinder with the auxiliary chamber, repeating the above automated process. This achieves unmanned operation of the entire process from transportation and alignment to feeding and fastening, greatly improving work efficiency and safety.

[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
