[0002] During the production process of photovoltaic modules, lamination is required. After the lamination process is completed, the curing glue in the photovoltaic modules will overflow from the four sides of the photovoltaic modules, and the laminated photovoltaic modules need to be sent into a trimming device for trimming.

[0003] In the prior art, when trimming a photovoltaic module with a trimming device, first, the photovoltaic module is sent into the trimming device for positioning. After positioning, the photovoltaic module is fixed, and then a cutting structure is used to cut and trim the edge of the photovoltaic module.

[0004] In the above process, the structures for positioning and fixing the photovoltaic module are mostly used separately, and they occupy a large area and the operation process is relatively complex. At the same time, in order to facilitate the subsequent use of the cutting structure, after the positioning structure positions the photovoltaic module, it needs to be reset to avoid affecting the movement of the cutting structure. This process leads to an extension of the time required for trimming the photovoltaic module and reduces the trimming efficiency. Summary of the Invention

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0042] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0043] Embodiment 1

[0044] Referring to Figures 1-8 , the present invention provides a photovoltaic module trimming device, including: a support frame 1. The support frame is a frame structure, and legs for support are fixed at its bottom end.

[0045] The conveying platform is arranged in the support frame 1 in a liftable manner. The surface of the conveying platform is used to convey and support the photovoltaic module 2. The conveying platform can be lifted in the support frame 1. When the conveying platform rises, its height is higher than the top end of the support frame 1. The photovoltaic module 2 on the production line enters the conveying platform and is conveyed to the surface by the conveying platform. The photovoltaic module 2 is supported. Subsequently, the conveying platform moves downward, driving the photovoltaic module 2 to correspond to the positioning member, the clamping member, and the edge trimming assembly for subsequent steps. After the edge trimming of the photovoltaic module 2 is completed, the conveying platform rises, and its height is higher than the top end of the support frame 1, sending the photovoltaic module 2 to the next production process and simultaneously receiving a new photovoltaic module 2 to be edge trimmed.

[0046] Four edge trimming assemblies are respectively arranged on the four inner walls of the support frame 1. The edge trimming assemblies are used for edge trimming the photovoltaic module 2. There are four edge trimming assemblies, which are respectively used for trimming the four side walls of the photovoltaic module 2.

[0047] The positioning and clamping assembly: At least one group is arranged on each side wall of the support frame 1. The positioning and clamping assembly includes a mounting frame 3 slidably connected to the side wall of the support frame 1. A positioning member and a clamping member are arranged on the mounting frame 3. The clamping member is located on the side close to the photovoltaic module 2 of the positioning member. The positioning member is in transmission connection with the clamping member. The photovoltaic module 2 is located between the two clamping ends of the clamping member.

[0048] It can be understood that at least one positioning and clamping assembly is arranged corresponding to each side edge of the photovoltaic module 2 to realize the positioning and clamping of the four side edges of the photovoltaic module 2. After the photovoltaic module 2 is clamped and fixed by the two clamping ends of the clamping member, the edge trimming assembly is started to trim the photovoltaic module 2.

[0049] When the two movable ends of the positioning member contact, the two clamping ends of the clamping member move away from each other. The two movable ends of the positioning member limit the side wall of the photovoltaic module 2. When the two movable ends of the positioning member separate, a gap is formed between the two movable ends for the trimming end of the edge trimming assembly to pass through. The two clamping ends of the clamping member move closer to each other and clamp and fix the photovoltaic module 2.

[0050] It can be understood that after the photovoltaic module 2 descends, the two movable ends of the positioning member contact, driving the mounting frame 3 to move towards the photovoltaic module 2. The movable ends of the positioning members located on the four side edges of the photovoltaic module 2 contact the side wall of the photovoltaic module 2 and push the photovoltaic module 2 to move, positioning the photovoltaic module 2. After the positioning is completed, the two movable ends of the positioning member move away from each other. During the movement of the movable ends of the positioning member, the two clamping ends of the clamping member are driven to move closer to each other. The two clamping ends cooperate to clamp and fix the photovoltaic module 2. At the same time, since the two movable ends of the positioning member move away from each other, a gap exists between the two movable ends for the trimming end of the edge trimming assembly to pass through, so that the presence of the positioning member does not affect the normal operation of the edge trimming assembly.

[0051] For a further optimized solution, refer toFigure 3 , Figure 5 , Figure 6 The mounting bracket 3 has a U-shaped structure. The two movable ends of the positioning member are two sliding columns 4. The two sliding columns 4 are respectively inserted and slide through the bottom end and the top end of the support frame 1. The two sliding columns 4 are separated from each other by an elastic member. The closer ends of the two sliding columns 4 are in contact through a driving member, and the closer ends of the two sliding columns 4 are in contact to limit the side of the photovoltaic module 2.

[0052] Specifically, the mounting bracket 3 includes two horizontal plates perpendicular to the support frame 1, and a vertical plate for connecting and fixing the two horizontal plates. The two sliding columns 4 are inserted through the two horizontal plates. Under the action of the elastic member, the two sliding columns 4 tend to move away from each other. Under the action of the driving member, the two sliding columns 4 are driven to approach each other. When the closer ends of the two sliding columns 4 are in contact, the two sliding columns 4 cooperate to form a columnar structure with no gap at the connection. This columnar structure contacts the side of the photovoltaic module 2 to limit the side wall of the photovoltaic module 2. When the driving member does not apply force to the sliding column 4, the two sliding columns 4 move away from each other under the action of the elastic member, and there is a gap between the closer ends of the two sliding columns 4.

[0053] Further optimized solution, referring to Figure 3 , Figure 5 , Figure 6 , Figure 7 The elastic member includes two circular ring plates 5 sleeved and fixed on the closer ends of the two sliding columns 4. The two circular ring plates 5 are located on both sides of the photovoltaic module 2. A compression spring 6 is sleeved on the sliding column 4. The two ends of the compression spring 6 are respectively fixed to one end of the circular ring plate 5 and the inner wall of the mounting bracket 3.

[0054] The circular ring plate 5 cooperates with the mounting bracket 3. When the two sliding columns 4 approach each other, the compression spring 6 is stretched. When the extrusion on the sliding column 4 is released, the compression spring 6 resets and makes the two sliding columns 4 move away from each other.

[0055] Further optimized solution, referring to Figure 3 , Figure 5 , Figure 6 , Figure 7 The driving member includes two fixing brackets 7 fixed on the outer walls of the bottom end and the top end of the mounting bracket 3. A first telescopic cylinder 8 is fixed on the fixing bracket 7. The movable end of the first telescopic cylinder 8 contacts the end of the sliding column 4 far from the other sliding column 4.

[0056] It can be understood that under the action of the first telescopic cylinder 8, the two sliding columns 4 are driven to approach each other and contact to form a columnar structure. When the movable end of the first telescopic cylinder 8 resets, the two sliding columns 4 separate.

[0057] Further optimized solution, referring to Figure 3 , Figure 5 , Figure 6 , Figure 7The two clamping ends of the clamping member include two sliding plates 9. The two sliding plates 9 are respectively inserted and slid on the top and bottom ends of the mounting frame 3. The mutually approaching ends of the two sliding plates 9 are fixedly connected with clamping plates 10. The photovoltaic module 2 is located between the two clamping plates 10, and the two clamping plates 10 are in contact with the photovoltaic module 2 to clamp and fix the photovoltaic module 2.

[0058] For a further optimized solution, refer to Figure 7 、 Figure 8 , a transmission groove 11 is opened on the end of the mounting frame 3 close to the photovoltaic module 2. Two transmission gears 12 are respectively arranged in the two transmission grooves 11. The transmission gears 12 are rotatably connected with the mounting frame 3. A driving plate 13 is arranged on the side of the transmission gear 12 away from the sliding plate 9. The driving plate 13 is slidably connected with the mounting frame 3. Rack bars 14 meshing with the transmission gears 12 are respectively fixedly connected to the sides of the driving plate 13 and the sliding plate 9 close to the transmission gears 12.

[0059] It can be understood that when the driving plate 13 rises, the driving plate 13 drives the transmission gear 12 to rotate, and causes the sliding plate 9 to descend. When the driving plate 13 descends, the driving plate 13 drives the transmission gear 12 to rotate, and causes the sliding plate 9 to rise.

[0060] Two lifting plates 15 are fixedly connected to the side of the driving plate 13 away from the transmission gear 12. A connecting plate 16 is fixedly connected to the outer wall of the sliding column 4. The connecting plate 16 is located between the two lifting plates 15, and the sliding column 4 drives the driving plate 13 to lift through the connecting plate 16 and the lifting plates 15.

[0061] It can be understood that when the two sliding columns 4 approach each other, the connecting plate 16 on the sliding column 4 drives the lifting plate 15 to descend, drives the driving plate 13 to descend through the lifting plate 15, and the driving plate 13 causes the sliding plate 9 to rise through the transmission gear 12, and the two clamping plates 10 are separated. When the two sliding columns 4 move away from each other, the connecting plate 16 on the sliding column 4 drives the lifting plate 15 to rise, drives the driving plate 13 to rise through the lifting plate 15, and the driving plate 13 causes the sliding plate 9 to descend through the transmission gear 12, and the two clamping plates 10 approach each other and clamp the photovoltaic module 2.

[0062] For a further optimized solution, refer to Figure 1 、 Figure 2 、 Figure 3 , the mounting frame 3 penetrates through the side wall of the support frame 1 and is slidably connected with the side wall of the support frame 1. A second telescopic cylinder 17 is fixedly connected to the outer wall of the support frame 1. The movable end of the second telescopic cylinder 17 is fixedly connected to the inner wall of the mounting frame 3.

[0063] It can be understood that the second telescopic cylinder 17 is used to drive the mounting bracket 3 to move on the support bracket 1. When the two sliding columns 4 come into contact to position the photovoltaic module 2, according to the size of the photovoltaic module 2, the second telescopic cylinders 17 located on the four sides of the photovoltaic module 2 extend and retract a certain distance to ensure that the photovoltaic module 2 is in the correct position to be trimmed. After the trimming of the photovoltaic module 2 is completed, the clamping plate 10 releases the clamping of the photovoltaic module 2, and the second telescopic cylinder 17 drives the mounting bracket 3 to reset, so that the photovoltaic module 2 can rise under the action of the conveying table.

[0064] For a further optimized solution, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , the trimming assembly includes a moving track 18 connected to the inner wall of the mounting bracket 3. There is a third telescopic cylinder 19 mounted on the moving track 18. The end of the third telescopic cylinder 19 is fixedly connected with a trimming knife 20. When the two sliding columns 4 are separated, the trimming knife 20 passes through between the two sliding columns 4.

[0065] It can be understood that the moving track 18 can be a chain or other horizontal moving structures. The third telescopic cylinder 19 is fixed on the moving track 18. The movable end of the third telescopic cylinder 19 extends to drive the trimming knife 20 to the trimming position, and then the moving track 18 moves horizontally to drive the trimming knife 20 to move for trimming.

[0066] Specifically, there are two third telescopic cylinders 19 arranged on one moving track 18, and the two third telescopic cylinders 19 move simultaneously on the moving track 18. When trimming, one of the third telescopic cylinders 19 drives the trimming knife 20 to pop out and contact the side of the photovoltaic module 2. Then the moving track 18 drives the third telescopic cylinder 19 to move in one direction. After trimming a part of the side of the photovoltaic module 2, this third telescopic cylinder 19 resets, and the other third telescopic cylinder 19 drives the other trimming knife 20 to pop out, and the moving track 18 moves in the other opposite direction, and the two trimming knives 20 cooperate to trim the photovoltaic module 2.

[0067] For a further optimized solution, referring to Figure 1 、 Figure 2 、 Figure 3 , the conveying table includes a platform 21 arranged in the mounting bracket 3. Two groups of conveyor belts 22 are fixedly connected to the top end of the platform 21. The photovoltaic module 2 is located on the surfaces of the two groups of conveyor belts 22. A lifting cylinder 23 is fixedly connected to the side of the platform 21 away from the conveyor belts 22. The photovoltaic module 2 on the conveyor belts 22 is lifted by the lifting cylinder 23.

[0068] The lifting cylinder 23 drives the conveyor belts 22 to lift, thereby driving the photovoltaic module 2 to lift.

[0069] A method for trimming a photovoltaic module, the operation steps include:

[0070] S1. Place the photovoltaic module 2 on the conveying platform and drive the conveying platform to descend. The surface height of the conveyor belt 22 is higher than the top height of the support frame 1. After the photovoltaic module 2 on the previous production line enters the conveyor belt 22 and is laid on the conveyor belt 22, the lifting cylinder 23 operates to drive the photovoltaic module 2 to descend to a predetermined position.

[0071] S2. Start the positioning member and the mounting bracket 3, drive the two movable ends of the positioning member to contact, drive the mounting bracket 3 to move, and the two movable ends of the positioning member position the photovoltaic module 2. Start the two first telescopic cylinders 8, and the movable ends of the first telescopic cylinders 8 drive the two sliding columns 4 to approach each other to form a cylinder. The mounting bracket 3 drives the formed cylinder to move and push the photovoltaic module 2 to position the photovoltaic module 2.

[0072] S3. Drive the two movable ends of the positioning member to separate, and the positioning member drives the two clamping ends of the clamping member to approach and clamp the photovoltaic module 2. After the photovoltaic module 2 is positioned, the first telescopic cylinder 8 resets, and the two sliding columns 4 separate under the action of the compression spring 6. The connecting plate 16 on the sliding column 4 drives the lifting plate 15 to rise, drives the driving plate 13 to rise through the lifting plate 15, and the driving plate 13 makes the sliding plate 9 descend through the transmission gear 12, and the two clamping plates 10 clamp the photovoltaic module 2.

[0073] S4. Start the trimming component to trim the photovoltaic module 2. Start the third telescopic cylinder 19 and the moving track 18 to trim the photovoltaic module 2.

[0074] S5. Reset the positioning member, and the two clamping ends of the positioning member driving the clamping member release the clamping of the photovoltaic module 2. Start the two first telescopic cylinders 8, and the movable ends of the first telescopic cylinders 8 drive the two sliding columns 4 to approach each other. The connecting plate 16 on the sliding column 4 drives the lifting plate 15 to descend, drives the driving plate 13 to descend through the lifting plate 15, and the driving plate 13 makes the sliding plate 9 rise through the transmission gear 12, and the two clamping plates 10 separate. At the same time, the second telescopic cylinder 17 drives the mounting bracket 3 to reset.

[0075] S6. Drive the conveying platform to rise and export the trimmed photovoltaic module 2. Start the lifting cylinder 23, and drive the photovoltaic module 2 to rise through the lifting cylinder 23 and enter the next process.
