Description

Technical Field

[0001] This application relates to the field of solar panel technology, and in particular to a top frame correction device for a solar grid. Background Technology

[0002] Solar panels are devices that convert sunlight into electrical energy. A solar screen printing plate refers to the screen printing template for solar panels, also known as a screen or silkscreen plate. The screen consists of a frame and a screen. During top-frame operation, the inner frame inside the top-frame machine moves to press the upper silk screen. The frame is then lifted to a dummy frame while a certain tension is applied. As the frame rises, it passes through the dummy frame, lifting the silk screen located on it. The tension of the silk screen increases as it is lifted until the required tension is reached. Once the silk screen reaches the required tension, the frame is glued in place, ensuring uniform stress on the entire surface of the silk screen.

[0003] An existing invention patent application with publication number CN117021738A discloses a solar grid panel top frame machine, including a frame, a mounting frame assembly on the frame, a lifting assembly on the mounting frame assembly, a driving assembly on the mounting frame assembly, a left top frame assembly on the mounting frame assembly, a right top frame assembly on the mounting frame assembly, a front clamping assembly on the mounting frame assembly, a rear clamping assembly on the mounting frame assembly, and an electrical control system on the frame; the front clamping assembly includes a track fixed on the frame, a partition fixed in the track, a clamping frame slidably disposed in the track, a long rod that passes through and rotatably disposed on the clamping frame, and two discs fixed on the long rod; the front clamping assembly and the rear clamping assembly have the same structure and are centrally symmetrical.

[0004] Regarding the aforementioned technologies, the inventors believe that after adjusting the spacing of the threads, due to the large number of threads, it is difficult to ensure that the distance between adjacent threads is consistent, and the correction of the thread positions is time-consuming and laborious, which needs to be improved. Summary of the Invention

[0005] This application provides a top frame correction device for a solar screen, which can automatically correct the distance between adjacent wires, reducing labor intensity.

[0006] This application provides a top frame correction device for a solar grid, which adopts the following technical solution: A top frame correction device for a solar grid includes a dummy frame, a drive mechanism, and a top plate. The dummy frame is fixed to a frame, and the top plate is driven to rise and fall by the drive mechanism. The top plate is used to place the grid frame. A round rod and a guide rod pass through the dummy frame. A corrugated tube is sleeved on the round rod. A groove on the outer wall of the corrugated tube is used for embedding wires. The wires pass around the guide rods. A guide rail is fixed to the dummy frame. Two supports are slidably connected to the guide rail. Each of the two supports is fixed with a limit ring. The two limit rings are sleeved in the groove on the outer wall of the corrugated tube. A locking structure is provided on the support.

[0007] By adopting the above technical solution, the wires are routed around the guide rod and the corrugated pipe. Each wire is embedded in the groove on the outer wall of each section of the corrugated pipe. The length of each section of the corrugated pipe is adjusted using supports, and the number of wires corresponding to the mesh frame is also adjusted. After adjustment, under the combined effect of the corrugated pipe's own elasticity, the length of each section of the corrugated pipe adaptively adjusts to be of equal length, thus ensuring that the spacing between adjacent wires is the same. This eliminates the need for individual manual adjustment of the wire positions, significantly reducing labor.

[0008] Optionally, the locking structure includes a locking bolt, which is threadedly connected to the support, and the end of the locking bolt abuts against the surface of the guide rail.

[0009] By adopting the above technical solution, the position of the support is fixed by tightening the locking bolts.

[0010] Optionally, the round rod is slidably connected to a plurality of sliding sleeves, and the sliding sleeves are fixed with an arc-shaped rod by a connecting rod. The arc-shaped rod is embedded in the groove of the inner wall of the bellows.

[0011] By adopting the above technical solution, the inner side of the corrugated pipe is supported by an arc-shaped rod, which improves the shape stability of the corrugated pipe and prevents it from collapsing under gravity.

[0012] Optionally, the outer sleeve of the round rod is provided with a plurality of springs, the two ends of which abut against the ends of the adjacent sliding sleeves.

[0013] By adopting the above technical solution, after the corrugated tube expands and contracts, the elastic force of spring one helps to ensure that the length of each section of the corrugated tube is equal, and the spacing between adjacent wires remains consistent.

[0014] Optionally, the sliding sleeve, spring 1, and round rod are coated with lubricating oil.

[0015] By adopting the above technical solution, the resistance of the sliding sleeve and spring to sliding outside the round rod is reduced by lubricating oil, thus avoiding excessive friction that makes it difficult for the sliding sleeve to slide.

[0016] Optionally, the dummy frame is fixed with a drive motor, and the output end of the drive motor is fixed to the round rod.

[0017] By adopting the above technical solution, the drive motor drives the round rod to rotate, the round rod drives the bellows to rotate, and the friction of the outer wall of the bellows pulls the thread to move and straightens the thread.

[0018] Optionally, a rotating sleeve is rotatably connected to the end of the round rod away from the drive motor. The rotating sleeve is fixed to the dummy frame, and a vibration structure is provided on the rotating sleeve.

[0019] By adopting the above technical solution, the vibration structure applies vibration to the round rod. The vibration of the round rod causes each section of the bellows to be of equal length under its own elasticity, and avoids the sliding sleeve from being stuck on the surface of the round rod due to static friction and being unable to slide.

[0020] Optionally, the vibration structure includes an adjusting bolt, which is threadedly connected to a rotating sleeve. A groove is provided inside the adjusting bolt, and a retaining ball is slidably connected to the groove. A spring is provided between the retaining ball and the bottom wall of the groove.

[0021] Optionally, the vibration structure further includes a groove formed on the outer wall of the round rod for inserting a ball.

[0022] By adopting the above technical solution, when the round rod rotates to the position where the groove is directly opposite the ball, the ball enters the groove under the elastic force of the second spring. Then, as the round rod rotates, the ball disengages from the groove, generating vibration during this process.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Under the combined action of the corrugated pipe's own elasticity and the spring, the length of each section of the corrugated pipe is adaptively adjusted to be of equal length, so the spacing between adjacent threads is the same, eliminating the need for manual adjustment of the thread positions and greatly reducing the workload. 2. Vibration is applied to the round rod through a vibration structure to further ensure that each section of the bellows is of equal length; 3. By sliding the support, the distance between adjacent threads can be adjusted, and the number of threads corresponding to the mesh frame can be adjusted. The position of the threads is easy to adjust. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 This embodiment discloses a top frame correction device for a solar screen, including a dummy frame 1, a drive mechanism 5, and a top plate 51. The dummy frame 1 is fixed to the frame, and the top plate 51 is driven to rise and fall by the drive mechanism 5, which can be a pneumatic cylinder, a hydraulic cylinder, or an electric lifting mechanism. The top plate 51 is used to place the screen frame. After the height of the top plate 51 rises, the top surface of the screen frame rests on the bottom of the wire at the dummy frame 1, thereby making the wire taut on the screen frame.

[0028] The dummy frame 1 is fitted with a round rod 2 and a guide rod 11. The round rod 2 is fitted with a corrugated tube 3, which is telescopic. The groove on the outer wall of the corrugated tube 3 is used for embedding the thread. There are two sets of the combination of round rod 2 and corrugated tube 3, located on the left and right sides of the dummy frame 1, respectively, for tightening the thread. Several guide rods 11 are provided. The height of the guide rods 11 is lower than that of the round rod 2. The thread passes around the guide rods 11, and the direction of the thread is adjusted through the guide rods 11.

[0029] A drive motor 12 is fixed to the dummy frame 1, and the output end of the drive motor 12 is fixed to the round rod 2. The number of drive motors 12 corresponds to the number of round rods 2. The two drive motors 12 rotate in the same direction and pull the thread to move through the friction of the outer wall of the corrugated tube 3. The left side of the dummy frame 1 is the position of the thread input device. The drive motor 12 on the right side rotates faster than the drive motor 12 on the left side, so the corrugated tube 3 on the right side rotates faster, thereby straightening the thread between the two corrugated tubes 3.

[0030] Reference Figure 1 and Figure 2The dummy frame 1 has two fixed guide rails 13, located on the inner walls of the left and right sides respectively. Each guide rail 13 has two slidably connected supports 14, each support 14 having a limiting ring 15 fixed to it. The limiting rings 15 are fitted into grooves on the outer wall of the corrugated pipe 3. Each limiting ring 15 consists of two half-rings fixed with bolts. By sliding the supports 14 along the guide rail 13, the limiting rings 15 drag the corresponding parts of the corrugated pipe 3, adjusting the distance between the two limiting rings 15 to lengthen or shorten the corrugated pipe 3, thereby adjusting the distance between adjacent threads. By separating the limiting rings 15 into two half-rings, the limiting rings 15 can be separated from the corrugated pipe 3, allowing adjustment of the position of the limiting rings 15 on the corrugated pipe 3 and the number of sections of the corrugated pipe 3 between the two limiting rings 15. The guide rails 13 have graduations along their length for easy identification of the support 14 positions.

[0031] The support 14 is provided with a locking structure, which includes a locking bolt 16. The locking bolt 16 is threadedly connected to the support 14, and the end of the locking bolt 16 abuts against the surface of the guide rail 13. By tightening the locking bolt 16, the position of the support 14 is fixed.

[0032] Reference Figure 3 Multiple sliding sleeves 21 are slidably connected to the outer side of the round rod 2. A keyway structure prevents relative rotation between the sliding sleeves 21 and the round rod 2. An arc-shaped rod 22 is fixed to the sliding sleeve 21 via a connecting rod. The arc-shaped rod 22 is embedded in a groove on the inner wall of the bellows 3. The arc-shaped rod 22 can be annular or segmented. When the bellows 3 expands or contracts, the sliding sleeves 21 slide adaptively outside the round rod 2. The arc-shaped rod 22 supports the inner side of the bellows 3, improving the shape stability of the bellows 3 and preventing it from collapsing under gravity. Furthermore, when the round rod 2 rotates, it drives the arc-shaped rod 22 to rotate via the sliding sleeves 21. The arc-shaped rod 22 then drives the bellows 3 to rotate through friction, improving the reliability of the round rod 2 driving the bellows 3 to rotate.

[0033] Multiple springs 23 are fitted around the outer sleeve of the round rod 2, with each end of spring 23 abutting against the end of an adjacent sliding sleeve 21. All springs 23 are identical and provide the same elastic force. As the bellows 3 expands and contracts, the elastic force of the springs 23 assists in ensuring that the length of each section of the bellows 3 is equal, thus maintaining consistent spacing between adjacent threads. Lubricating oil is applied between the sliding sleeves 21, springs 23, and the round rod 2. This lubrication reduces the resistance to sliding the sliding sleeves 21 and springs 23 outside the round rod 2, preventing excessive friction that would hinder the sliding of the sliding sleeves 21.

[0034] Reference Figure 1 The end of the round rod 2 away from the drive motor 12 is rotatably connected to a rotating sleeve 4, which is fixed to the dummy frame 1. The rotating sleeve 4 is provided with a vibration structure.

[0035] Reference Figure 4The vibration structure includes an adjusting bolt 41 and a groove 24 formed on the outer wall of the round rod 2. The adjusting bolt 41 is threadedly connected to the rotating sleeve 4. A sliding groove 42 is formed inside the adjusting bolt 41, and a retaining ball 43 is slidably connected to the sliding groove 42. A spring 44 is provided between the retaining ball 43 and the bottom wall of the sliding groove 42. The sliding groove 42 is a constricted groove, and part of the retaining ball 43 extends out of the adjusting bolt 41 but cannot disengage from the sliding groove 42.

[0036] The groove 24 on the outer wall of the round rod 2 is used for the insertion of the retaining ball 43. The operator tightens the adjusting bolt 41 by hand until the threaded end contacts the outer wall of the round rod 2, avoiding over-tightening. When the round rod 2 rotates until the groove 24 is directly opposite the retaining ball 43, the retaining ball 43 enters the groove 24 under the elastic force of the spring 44. Subsequently, the retaining ball 43 disengages from the groove 24 as the round rod 2 rotates, generating vibration during this process. The vibration of the round rod 2 causes each section of the bellows 3 to be of equal length under its own elasticity, and prevents the sliding sleeve 21 from being stuck on the surface of the round rod 2 due to static friction. On the other hand, the vibration gradually loosens the adjusting bolt 41. After the adjusting bolt 41 moves upward, the retaining ball 43 will not enter the groove 24. Therefore, the vibration can automatically stop after the round rod 2 rotates several times, preventing the wire from shaking during top frame operation.

[0037] The implementation principle of the top frame correction device for a solar screen according to an embodiment of this application is as follows: Wires are wound around the guide rod 11 and the corrugated pipe 3, with each wire embedded in the groove on the outer wall of each section of the corrugated pipe 3. The length of each section of the corrugated pipe 3 is adjusted by the support 14, and the number of wires corresponding to the screen frame is also adjusted. After adjustment, under the combined action of the corrugated pipe 3's own elasticity and the spring 23, the length of each section of the corrugated pipe 3 adaptively adjusts to be equal, thus ensuring that the spacing between adjacent wires is the same. This eliminates the need for manual adjustment of the wire positions, significantly reducing labor.

[0038] Start the drive motor 12, and the round rod 2 drives the bellows 3 to rotate. The bellows 3 straightens and tightens the threads through friction, and each thread can be pulled. At the same time, the vibration structure applies vibration to the round rod 2 to further ensure that each section of the bellows 3 is of equal length.

[0039] Then, the top plate 51 is raised by the drive mechanism 5. The top plate 51 drives the mesh frame to move upward. After the mesh frame presses against the wire, it rises to a position flush with the dummy frame 1. Then, the wire is pasted and cut. After completion, the height of the top plate 51 is lowered, the mesh frame is rotated 90 degrees, and the top frame operation is repeated to create a horizontal and vertical mesh structure.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
