[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] Next, in combination with the drawings and specific embodiments, the present utility model will be further described:

[0029] As Figures 1-5 shown, a photovoltaic film winding device includes a winding assembly 1. The winding assembly 1 includes a frame 11, a winding roller 12 and a winding driver 13. Both ends of the winding roller 12 are rotatably connected to the frame 11. The winding driver 13 is arranged on the frame 11 and its driving end is connected to one end of the winding roller 12;

[0030] It further includes a pressing mechanism disposed below the winding roller 12. The pressing mechanism includes a frame-shaped bracket 2, and a rotatable roller assembly 3 is disposed inside the frame-shaped bracket 2. The roller assembly 3 is in close contact with the lower surface of the winding roller 12. The pressing mechanism further includes a roller driving assembly 4, and the roller driving assembly 4 is used to adjust the pressing force of the roller assembly 3 on the winding roller 12 in real time.

[0031] In this embodiment, during the process of the winding roller 12 winding the photovoltaic film 100, the diameter of the winding roller 12 will gradually increase. Therefore, in order not to affect the winding, the distance between the roller assembly 3 and the winding roller 12 is adjusted in real time through the roller driving assembly 4 according to the change in the diameter of the winding roller 12, so that the pressing force of the roller assembly 3 on the winding roller 12 is maintained at a set value, thereby tightly pressing the wound photovoltaic film 100 without damage in real time, playing a role in preventing the winding from loosening. The process does not rely on the tension force and does not require additional pressing, and can conveniently seal the wound photovoltaic film 100 at any time, simplifying the winding control and improving the winding quality and efficiency.

[0032] In addition, in this embodiment, since the roller assembly 3 is in close contact with the winding roller 12, the rotation of the winding roller 12 can drive the roller assembly 3 to rotate synchronously, thereby playing a role in guiding and flattening the photovoltaic film 100 and improving the winding quality.

[0033] Further, as Figures 1-5 shown, in order to improve the pressing effect on the winding roller 12 and prevent the wound photovoltaic film 100 from loosening; the roller assembly 3 includes a front roller 31 and a rear roller 32 which are oppositely arranged front and rear.

[0034] Further, as Figures 1-5 shown, the roller driving assembly 4 includes two driving assemblies 42 which are oppositely arranged below both sides of the frame-shaped bracket 2, and an elastic telescopic assembly 5 is disposed between the driving assembly 42 and the frame-shaped bracket 2.

[0035] In this embodiment, the elastic telescopic assembly 5 is used to generate a flexible pressing force of the roller assembly 3 on the winding roller 12, avoiding damage to the photovoltaic film 100 caused by the pressing force and improving the effectiveness and reliability of the pressing.

[0036] Further, as Figures 1-5 shown, the elastic telescopic assembly 5 includes a sleeve 51 whose one end is connected to the frame-shaped bracket 2. An elastic member 52 and a piston rod 53 are sequentially arranged in the sliding cavity of the sleeve 51 in a direction away from the frame-shaped bracket 2. One end of the piston rod 53 is slidably connected to the sliding cavity of the sleeve 51, and the other end is connected to the driving end of the driving assembly 42.

[0037] In this embodiment, when the driving component 42 drives the piston rod 53 upward, the piston rod 53 slides upward relative to the sleeve 51 fixedly connected to the frame-shaped bracket 2. At this time, the sleeve 51 and the pressing roller assembly 3 are subjected to a downward acting force from the winding roller 12, causing the piston rod 53 to squeeze the elastic member 52, thereby generating a flexible pressing force of the pressing roller assembly 3 on the winding roller 12. During the process, as the diameter of the winding roller 12 gradually increases after winding the photovoltaic film 100, the driving component 42 automatically controls the pressing roller assembly 3 to move downward to ensure that the pressing force of the pressing roller assembly 3 on the winding roller 12 is maintained at a set value, so as to tightly press the wound photovoltaic film 100 without damage in real time.

[0038] Further, as Figures 1-5 shown, in order to accurately and automatically control the pressing force of the pressing roller assembly 3 on the winding roller 12 at a set value during the winding process and improve the winding reliability; a pressure sensor 6 is arranged in the sliding cavity of the sleeve 51, the pressure sensor 6 is located between the elastic member 52 and the frame-shaped bracket 2, and the pressure sensor 6 is electrically connected to the driving component 42. During operation, the driving component 42 automatically adjusts the distance between the pressing roller assembly 3 and the winding roller 12 in real time according to the pressure information detected by the pressure sensor 6, so as to tightly press the wound photovoltaic film 100 without damage while winding.

[0039] Further, as Figures 1-5 shown, the two driving components 42 include a cylinder body 421, a lead screw pair 422 is arranged in the cylinder body 421, one end of the lead screw of the lead screw pair 422 away from the nut is rotatably connected to the cylinder body 421, a driving rod 423 is arranged on the side of the nut of the lead screw pair 422 away from the lead screw, and the other end of the driving rod 423 passes through the cylinder body 421 and is connected to the piston rod 53 of the elastic telescopic component 5;

[0040] The pressing roller driving component 4 further includes an electric cylinder 43 for driving the two nuts to move synchronously up and down relative to the cylinder body 421.

[0041] In this embodiment, the two nuts are driven to lift synchronously by a single electric cylinder 43, and the nuts are stably lifted under the action of the lead screw, so as to realize the synchronous lifting of the two driving rods 423, ensure the smoothness of the lifting process of the pressing roller assembly 3, and avoid the pressing roller assembly 3 tilting and not fitting smoothly with the winding roller 12, which affects the winding and pressing effects.

[0042] Further, as Figures 1-5 shown, through holes 4211 extending up and down are formed on the surfaces of the two cylinder bodies 421 close to each other, the electric cylinder 43 is arranged between the two cylinder bodies 421, the driving end of the electric cylinder 43 is connected to the middle of the connecting plate 7, and the two ends of the connecting plate 7 respectively pass through the through holes 4211 and are connected to the corresponding nuts.

[0043] In this embodiment, the above structure enables a single electric cylinder 43 to drive the two nuts to lift and lower synchronously relative to the cylinder body 421 through the connecting plate 7, and the driving process is stable and reliable.

[0044] Further, the elastic member 52 is one or a combination of a spring or an elastic rubber. Those skilled in the art can make various corresponding changes and deformations according to the technical solutions and concepts described above, and all such changes and deformations should fall within the protection scope of the claims of the utility model patent.
