The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0029] like Figure 1-4 As shown, a novel device for removing the back film of a photovoltaic module 100 comprises a roller conveyor mechanism 1 for transferring the photovoltaic module 100, a frame 2 is arranged above the roller conveyor mechanism 1, and a heating mechanism 3 and a back film winding mechanism 4 are arranged on the frame 2 in sequence from the feeding end to the lower feeding end, and the heating mechanism 3 is used to heat the photovoltaic module 100;

[0030] The back film winding mechanism 4 includes a U-shaped frame 41, and limit plates 42 are relatively arranged in the front and rear of the U-shaped frame 41, and the limit plates 42 are fixedly connected to the U-shaped frame 41. The outer sides of the two limit plates 42 are respectively provided with movable plates 43, and the upper ends of the two movable plates 43 are slidably connected to the upper end surface of the U-shaped frame 41, and the lower ends are respectively provided with a coaxial and only rotatable first winding roller 44 and a second winding roller 45, and the ends of the first winding roller 44 and the second winding roller 45 that are close to each other respectively penetrate the limit plates 42 and are connected, and a winding driver 46 is arranged on the outer side of one of the movable plates 43, and the driving end of the winding driver 46 is connected to the first winding roller 44, and the first winding roller 44 and the second winding roller 45 cannot rotate with each other after being connected;

[0031] The back film winding mechanism 4 further includes a moving plate driving assembly 47 , and the moving plate driving assembly 47 is used to drive the two moving plates 43 to symmetrically approach or move away from the limiting plate 42 .

[0032] In this embodiment, the heating mechanism 3 is closely attached to the transported heated photovoltaic assembly 100 , and the back film 200 is separated from the main surface of the photovoltaic assembly 100 by heating the photovoltaic assembly 100 .

[0033] Working principle: initially, the first winding roller 44 is connected to the second winding roller 45, and the first winding roller 44 and the second winding roller 45 can be driven to rotate synchronously through the winding driver 46, and the first winding roller 44 and the second winding roller 45 form a winding roller assembly. During operation, the photovoltaic component 100 placed on the roller conveyor mechanism 1 is heated by the heating mechanism 3, and the back film 200 is separated from the surface of the photovoltaic component 100, and one end of the back film 200 is connected to the surface of the winding roller assembly located between the two limiting plates 42, and rotated under the action of the winding driver 46 to wind the separated back film 200; after the back film 200 is wound, the moving plate driving assembly 47 is driven forward, driving the two moving plates 43 to move symmetrically away from each other, so that the end connected to the first winding roller 44 and the second winding roller 45 is gradually separated. Due to the limitation of the plate 42, the rolled back film 300 cannot follow the axial movement of the first winding roller 44 or the second winding roller 45. During the process, the first winding roller 44 and the second winding roller 45 gradually separate from the rolled back film 300 (the winding drive 46 maintains the driving state). After completely separating, the rolled back film 300 automatically falls down and can be manually recovered. Then the moving plate driving assembly 47 drives the moving plate 43 to approach symmetrically until the first winding roller 44 and the second winding roller 45 are aligned and connected (the back film 200 is connected to the surface of the winding roller assembly and the first winding roller 44 and the second winding roller 45 are aligned manually), and the back film 200 of the next photovoltaic module 100 is to be processed; thereby, when the rolled back film 300 is removed, it is directly separated from the winding roller, and there is no need to replace the winding roller during the process. It is convenient, fast, reliable and low-cost.

[0034] Further, such as Figure 2 , 3 As shown in , 4, the moving plate driving assembly 47 includes a driving rod 471 and a driving rod driver 472, the driving rod 471 is rotatably arranged in the U-shaped frame 41, and the driving rod driver 472 is arranged outside the U-shaped frame 41, and its driving end is connected to one end of the driving rod 471;

[0035] The driving rod 471 includes a limiting section 471a in the middle, and a first thread section 471b and a second thread section 471c are respectively provided on both sides of the limiting section 471a, and the first thread section 471b and the second thread section 471c are provided with threads with the same lead and opposite rotation directions;

[0036] The two movable plates 43 are threadedly connected to the first thread segment 471b and the second thread segment 471c respectively, and the two limiting plates 42 are arranged at two ends of the limiting segment 471a.

[0037] In this embodiment, the driving rod driver 472 drives the driving rod 471 to rotate, driving the two movable plates 43 to symmetrically approach or move away from the limiting section 471a, thereby connecting or separating the first winding roller 44 and the second winding roller 45.

[0038] Further, such as Figure 2 , 3 As shown in 4, in order to ensure a stable connection between the first winding roller 44 and the second winding roller 45 and to prevent the first winding roller 44 from rotating relative to the second winding roller 45 in the connected state, thereby improving the transmission drive reliability; a groove 44a is provided on the end surface of the first winding roller 44 close to the second winding roller 45, and a boss 45a matching the groove 44a is provided on the end surface of the second winding roller 45 close to the first winding roller 44, and the cross-sections of the groove 44a and the boss 45a are non-circular.

[0039] Further, such as Figure 2 , 3 As shown in 4, in order to improve the rotation stability of the winding roller and prevent the winding roller from axially moving relative to the movable plate 43 to ensure the connection reliability; the first winding roller 44 and the second winding roller 45 are rotationally connected to the movable plate 43 through bearings respectively.

[0040] Further, such as Figure 2 , 3 As shown in Figure 4, the heating mechanism 3 includes an electric telescopic push rod 31 connected to the frame 2, the telescopic end of the electric telescopic push rod 31 is provided with a lifting plate 32, the lower surface of the lifting plate 32 is provided with a plurality of telescopic rods 33, the other end of the telescopic rod 33 is provided with a U-shaped frame 34, the outer sleeve of the telescopic rod 33 is provided with a spring 35, and a rotatable heating roller 36 is provided in the U-shaped frame 34.

[0041] In this embodiment, a heating tube is provided inside the heating roller 36. When in operation, the bottom of the heating roller 36 is driven by the electric telescopic push rod 31 to fit tightly with the photovoltaic module 100, thereby effectively preheating and heating the back film 200 on the photovoltaic module 100 without interfering with the transmission of the photovoltaic module 100, thereby facilitating the separation of the back film 200 from the main surface of the photovoltaic module 100.

[0042] In this embodiment, by setting the electric telescopic push rod 31, the telescopic rod 33 and the spring 35, the heating roller 36 is in close contact with the photovoltaic surface through flexible downward pressure, avoiding squeezing damage to the photovoltaic component 100, while meeting the heating requirements of photovoltaic components 100 of different sizes.

[0043] Further, such as Figure 2 , 3As shown in FIG. 4 , in order to ensure the smooth and reliable axial movement of the movable plate 43, a slide groove 41a is provided at the sliding connection between the U-shaped frame 41 and the movable plate 43, and a slider 43a is provided on the movable plate 43 to slide with the slide groove 41a.

[0045] In this embodiment, by setting a heating tube 5 with a clearance fit in the axial hole 45b of the second winding roller 45, the second winding roller 45 can be heated to facilitate separation of the surface of the second winding roller 45 from the rolled back film 300, and the heat can be transferred to the first winding roller 44, further improving the effect of separating the rolled back film 300.

[0046] In this embodiment, the sliding rod 7 and the connecting plate 6 are arranged so that the heating tube 5 can follow the axial movement of the second winding roller 45, thereby avoiding interference caused by the rolled backing film 300 detaching from the winding roller and improving reliability.

[0047] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the utility model patent.
