Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of equipment accessories, specifically relates to a gravity self -sliding type multifunctional steel structure platform. BACKGROUND

[0002] A photovoltaic module, also known as a solar panel, is made by connecting multiple solar cells in series or parallel to achieve higher voltage and current. The production process of a photovoltaic module can be roughly divided into the following steps: 1) silicon preparation:

[0003] Polysilicon production: Polysilicon is produced through methods such as chemical vapor deposition.

[0004] Monocrystalline silicon production: Monocrystalline silicon is produced through methods such as the Czochralski method.

[0005] 2) Silicon wafer preparation:

[0006] Cutting: Polysilicon or monocrystalline silicon ingots are cut into thin slices to form silicon wafers.

[0007] Cleaning: The cut silicon wafers need to be cleaned to remove surface impurities and cutting fluid.

[0008] 3) Solar cell fabrication:

[0009] Diffusion: PN junctions are formed on the surface of the silicon wafer by introducing dopants into the silicon wafer through diffusion processes.

[0010] Etching: Remove the damage layer and contaminants on the surface of the silicon wafer.

[0011] Coating: Anti-reflective film is coated on the surface of the silicon wafer to reduce light reflection and improve light absorption.

[0012] Print electrodes: Positive and negative electrodes are made on the silicon wafer through screen printing technology.

[0013] Sintering: High-temperature sintering forms good electrical contact between the electrodes and the silicon wafer.

[0014] 4) Photovoltaic module assembly:

[0015] Laminating: Multiple solar cells are connected in series or parallel and placed between two layers of glass with EVA adhesive film. Through the laminating machine, heat and pressure are applied to form a solid whole.

[0016] Frame installation: An aluminum frame is installed around the module to increase the strength and electrical conductivity of the module.

[0017] Terminal box installation: A terminal box is installed on the back of the module for external wire connection.

[0018] 5) Testing:

[0019] Performance testing: Test the electrical performance parameters of photovoltaic modules, such as open-circuit voltage, short-circuit current, and maximum output power.

[0020] Environmental testing: Aging tests, temperature cycling tests, humidity tests, etc., are conducted on photovoltaic modules to ensure their reliability and stability.

[0021] 6) Packaging and shipping: The photovoltaic modules that have completed testing are cleaned and dried, then packaged and shipped, ready for installation in photovoltaic power plants.

[0022] During the production of photovoltaic modules, semi-finished products need to be transferred from one process to the next. Currently, there are idlers installed between photovoltaic module production equipment to transfer the semi-finished photovoltaic modules. However, existing idlers are generally fixed installation structures, and multiple idlers are installed at the same height. This requires an additional power source to transport the semi-finished photovoltaic modules on the idlers. Furthermore, since the power source needs to be matched with a control cabinet for control, the manufacturing cost of the idlers increases. Utility Model Content

[0023] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a gravity self-sliding multi-functional steel structure platform.

[0024] The technical solution adopted to solve the above-mentioned technical problems is: a gravity self-sliding multi-functional steel structure platform, including a frame and a steel structure platform horizontally fixed to the top of the frame, and further including:

[0025] A swing frame is rotatably connected to both sides of the frame in the width direction, and the swing frame is located below the steel structure platform;

[0026] A pivot is horizontally rotatably connected to the outer wall of the swing frame at intervals along the length of the steel platform. Multiple support rollers are fixedly sleeved around the periphery of the pivot. The surface of the steel platform is provided with support roller clearance grooves to allow the support rollers to move freely through.

[0027] An angle adjustment component is provided on the frame, and the angle adjustment component is used to drive the swing frame to swing up and down.

[0028] Furthermore, when the swing frame is in a horizontal state, the longitudinal distance between the highest point of the periphery of the support roller and the top surface of the steel structure platform is not less than 5cm.

[0029] Furthermore, the surface of the support roller is provided with a rubber layer.

[0030] Furthermore, the angle adjustment assembly includes a mounting base hinged to the frame, a linear drive element connected to the surface of the mounting base, a movable block connected to the output end of the linear drive element, and the movable block hinged to the swing frame.

[0031] Furthermore, the outer wall of the frame is provided with a reinforcing beam, and the mounting base is hinged to the outer wall of the reinforcing beam.

[0032] Furthermore, each end of the pivot is slidably fitted with a correction wheel, the diameter of which is larger than that of the support wheel. The swing frame is provided with an intermittent correction assembly, which is used to drive the correction wheel to reciprocate linearly along the axis of the pivot when the pivot rotates. The surface of the steel platform is provided with a correction wheel clearance groove for the correction wheel to pass freely in linear motion.

[0033] Furthermore, the end face of the correction wheel is coaxially provided with a spline hole for the pivot to pass through freely, and the pivot is splinedly connected to the spline hole.

[0034] Furthermore, a sliding layer is fixed to one end face of the correction wheel facing the inside of the steel structure platform.

[0035] Furthermore, the intermittent correction assembly includes multiple fixed plates connected to the two sides of the swing frame in the width direction. The fixed plates have through holes on their surfaces for the pivot to pass through freely. A fixed ring is connected to the side of the fixed plate facing the correction wheel. Two mounting arms are fixedly connected to the side end of the fixed ring facing the correction wheel. A roller is rotatably connected to the end of the mounting arm away from the fixed ring. An arc-shaped protrusion is fixedly connected to the side end of the correction wheel facing the fixed ring. A reset structure is provided around the pivot. The reset structure is used to drive the correction wheel to move toward the fixed ring.

[0036] Furthermore, the reset structure includes a stop ring fixedly sleeved around the periphery of the pivot, and an elastic element is provided between the stop ring and the correction wheel. The elastic element is used to generate an elastic resisting force on the correction wheel toward the fixed ring side.

[0037] The beneficial effects of this utility model are as follows:

[0038] (1) In this utility model, by swinging the swing frame along the hinge point with the frame, the installation height of the support rollers corresponding to both ends of the frame length direction changes sequentially. When the photovoltaic module semi-finished product is placed on the support roller at the highest point, it can slide from the previous process to the next process on the support roller by its own gravity. Since there is no need to set up an additional power source and a control cabinet that matches the power source, the manufacturing cost is reduced to a certain extent. In addition, since the angle adjustment component can change the adjustment range of the swing frame, it can meet the turnover of photovoltaic module semi-finished products between different equipment.

[0039] (2) In this utility model, the correction wheel reciprocates along the axis of the pivot, thereby enabling the correction wheel to correct the photovoltaic module semi-finished product placed on the support roller, so that the photovoltaic module semi-finished product can be positioned correctly for the next process to pick up and position.

[0040] (3) In this utility model, the photovoltaic module semi-finished product moves on the support roller, thereby driving the support roller to rotate. When the support roller rotates, the pivot rotates synchronously, thereby causing the correction wheel to rotate synchronously. When the correction wheel rotates, the roller will roll on the end face of the correction wheel and the surface of the arc-shaped protrusion. Then, relying on the elastic resisting force of the reset structure on the correction wheel, the correction wheel can reciprocate along the axis of the pivot when the pivot rotates, thereby correcting and guiding the two sides of the photovoltaic module semi-finished product.

Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0053] like Figures 1-10 As shown, this embodiment provides a gravity self-sliding multi-functional steel structure platform, including a frame 1 and a steel structure platform 4 horizontally fixed to the top of the frame 1. The two ends of the length direction of the frame 1 correspond to the discharge end and input end of the photovoltaic module production equipment in the upper and lower processes, respectively. Two lugs are fixed to the bottom surface of the middle position of the frame 1. The two lugs are located on both sides of the width direction of the frame 1, and a support shaft is passed through the two lugs. A swing frame 8 is provided below the steel structure platform 4. The swing frame 8 has a rectangular frame structure. The length direction of the swing frame 8 is consistent with the length direction of the frame 1, and the width direction of the swing frame 8 is also consistent with the width direction of the frame 1. Two connecting lugs are welded to the downward side of the swing frame 8. Bearing seats are installed on the connecting lugs. The two ends of the support shaft are respectively inserted into the two bearing seats, so that the swing frame 8 is horizontally rotatably connected to the frame 1.

[0054] Multiple sets of bearing seats are installed on the upward-facing side of the swing frame 8. Each set of bearing seats consists of two bearing seats, distributed at both ends of the width direction of the swing frame 8. A pivot 9 is installed between each set of bearing seats. Multiple support rollers 5 are fixedly sleeved around the periphery of the pivot 9. The support rollers 5 are evenly distributed along the axial direction of the pivot 9. The surface of the steel platform 4 is provided with support roller clearance grooves 6 for the support rollers 5 to pass freely. In addition, a reinforcing beam is welded to each end of the frame 1 along its length direction. A first lug is welded to one of the reinforcing beams. A mounting base 10 is hinged to the first lug. A linear drive element 7 is connected to the mounting base 10. In this embodiment, the linear drive element 7 can be a cylinder or a hydraulic cylinder. A movable block 11 is fixedly connected to the output end of the linear drive element 7. A second lug is welded to the downward-facing side of the swing frame 8. The second lug is hinged to the movable block 11. The output of the linear drive element 7... When the output end is activated, the driving block 11 will move linearly, and the driving block 11 will push the second lug to move, thereby driving the swing frame 8 to swing around the axis of the support shaft. This causes the height of the support rollers 5 installed on the swing frame 8 to change sequentially along the length of the frame 1. As a result, when the photovoltaic module semi-finished product produced in the previous process falls onto the support roller 5 with the highest installation height, it can slide to the input end of the next process by its own weight. In addition, in order to ensure that each support roller 5 can protrude to the top surface of the steel platform 4 after the swing frame 8 swings, in this embodiment, when the swing frame 8 is in a horizontal state, the longitudinal distance between the highest point of the periphery of the support roller 5 and the top surface of the steel platform 4 is not less than 5cm. This makes the swing angle adjustment range of the swing frame 8 large, which is suitable for the turnover of most photovoltaic module equipment.

[0055] In addition, each end of the pivot 9 is slidably fitted with a correction wheel 3, and the end face of the correction wheel 3 is coaxially provided with a spline hole for the pivot 9 to pass through freely. The pivot 9 is splinedly connected to the spline hole. The diameter of the correction wheel 3 is larger than the diameter of the support roller 5. When the photovoltaic module semi-finished product slides and is conveyed on the support roller 5, the photovoltaic module semi-finished product may be tilted when it falls onto the support roller 5. This will cause the length direction of the two sides of the photovoltaic module semi-finished product to be non-parallel to the direction of movement of the photovoltaic module semi-finished product on the steel structure platform 4, thus affecting the positioning of the next process. In this embodiment, the correction wheel 3 is set to reciprocate along the axis of the pivot 9. When the photovoltaic module semi-finished product moves on the support roller 5, the support roller 5 rotates, which in turn drives the pivot 9 to rotate. The correction wheel 3 rotates synchronously and, through the reciprocating motion of the correction wheel 3, it squeezes the edge of the skewed photovoltaic module semi-finished product, thereby forcing the position of the photovoltaic module semi-finished product to be adjusted, thus realizing the correction of the photovoltaic module semi-finished product. At the same time, the surface of the steel platform 4 is also provided with a correction wheel clearance groove 2 for the correction wheel 3 to move freely in a straight line.

[0056] A sliding layer 12 is fixedly connected to one end face of the straightening wheel 3 facing the inner side of the steel platform 4. The sliding layer 12 can be a stainless steel layer, so that when the edge of the photovoltaic module semi-finished product contacts the surface of the sliding layer 12, the edge of the photovoltaic module semi-finished product can slide on the surface of the sliding layer 12. Multiple fixing plates 13 are connected to both sides of the swing frame 8 by screws. The surface of the fixing plate 13 has through holes for the pivot 9 to pass through freely. A fixing ring 14 is connected to the side surface of the fixing plate 13 facing the straightening wheel 3. Two mounting rings are fixedly connected to the side end face of the fixing ring 14 facing the straightening wheel 3. Arm 18, with a roller 19 rotatably connected to the end of the mounting arm 18 away from the fixed ring 14. An arc-shaped protrusion 15 is fixedly attached to the side end face of the straightening wheel 3 facing the fixed ring 14. The arc-shaped ends of the arc-shaped protrusion 15 have a smooth transition surface with the end face of the straightening wheel 3. A stop ring 16 is fixedly sleeved around the periphery of the pivot 9. The stop ring 16 corresponds to the side end face of the straightening wheel 3 facing away from the fixed ring 14. A spring 17 is provided between the stop ring 16 and the straightening wheel 3. The spring 17 is wrapped around the periphery of the pivot 9, and the two ends of the spring force elastically abut against the end face of the straightening wheel 3 and the end face of the stop ring 16, respectively.

[0057] The working principle of this embodiment is as follows:

[0058] When adjusting the height of the support roller 5 on the swing frame 8, the linear drive element 7 is activated first. The output end of the linear drive element 7 drives the movable block 11 to move, which in turn drives the swing frame 8 to swing around the axis of the support shaft. This makes the height of the support roller 5 corresponding to the previous process higher than the height of the support roller 5 corresponding to the next process. In this way, after the photovoltaic module semi-finished product produced in the previous process falls onto the support roller 5, it can slide on the support roller 5 under its own gravity. Furthermore, the surface of the support roller 5 is provided with a rubber layer (not shown in the figure). When the photovoltaic module semi-finished product slides on the support roller 5, it can drive the support roller 5 to rotate by relying on the large friction between the photovoltaic module semi-finished product and the rubber layer. When the support roller 5 rotates, it will synchronously drive the pivot 9 to rotate.

[0059] When pivot 9 rotates, it will drive the correction wheel 3 to rotate. When the correction wheel 3 rotates, the arc-shaped protrusion 15 on the end face of the correction wheel 3 also rotates synchronously. The spring 17 has an elastic resisting force on the correction wheel 3, so that when the correction wheel 3 rotates, the arc-shaped protrusion 15 can intermittently contact the roller 19. Specifically, when the arc-shaped protrusion 15 contacts the roller 19, the roller 19 will roll from the end face of the correction wheel 3 to the smooth transition surface, and then roll to the surface of the arc-shaped protrusion 15, thereby generating a thrust on the correction wheel 3 in the direction away from the fixed ring 14, so that the correction wheel 3 moves towards the inside of the steel platform 4, so that the correction wheels 3 at both ends of the same pivot 9 can move relatively close, thereby making the correction wheel 3 exert a squeezing force on the two sides of the skewed photovoltaic module semi-finished product, so that the photovoltaic module semi-finished product is forcibly guided. At the same time, the spring 17 is squeezed by the correction wheel 3 and accumulates elastic potential energy.

[0060] As the pivot 9 continues to rotate (provided that the photovoltaic module semi-finished product slides on the support roller 5 corresponding to the pivot 9), the roller 19 will roll from the surface of the arc-shaped protrusion 15 to the smooth transition surface, and then roll to the end face of the correction wheel 3. The elastic potential energy of the spring 17 is released, and the correction wheel 3 is driven to move in the opposite direction, so that the subsequent photovoltaic module semi-finished product can fall smoothly onto the support roller 5.

[0061] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model.
