Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic encapsulation films, and relates to a UV light curing device for photovoltaic panel films. Background Art

[0002] In the existing production process, positioning tapes are used to assist in the positioning of solar cells. Each module uses 20 - 28 tapes according to different product specifications. The adhesion between the tape and the film or the solar cell is used to assist in the positioning of the solar cell, preventing the offset of the solar cell during the lamination process. In the existing technical solution, the film has strong ductility and fluidity. During the lamination process, the film heats up and flows, which may cause the offset of the solar cell. The positioning tape may crush the solar cell during the manual or robotic pasting process. The adhesive on the positioning tape may generate bubbles during the lamination process, resulting in a reduction in the qualification rate of the module. Secondly, pasting the tape will affect the production efficiency and increase energy consumption at the same time. Summary of the Invention

[0003] The purpose of the utility model is to address the above problems existing in the prior art, and propose a UV light curing device for photovoltaic panel films, which solves the problems in the existing technical solution that the film has strong ductility and fluidity, the film heats up and flows during the lamination process, which may cause the offset of the solar cell, the positioning tape may crush the solar cell during the manual or robotic pasting process, the adhesive on the positioning tape may generate bubbles during the lamination process, resulting in a reduction in the qualification rate of the module, secondly, pasting the tape will affect the production efficiency and increase energy consumption at the same time.

[0004] The purpose of the utility model can be achieved by the following technical solutions:

[0005] A UV light curing device for photovoltaic panel films includes a curing device body. Guide frame plates are symmetrically and fixedly installed inside the curing device body. A fixed plate is fixedly inserted in the middle of the guide frame plates. A plurality of movable plates are equidistantly arranged on both sides of the fixed plate inside the guide frame plates. The gaps formed between the fixed plate, the movable plates, and adjacent movable plates correspond to the width of the photovoltaic panel solar cells. An adjusting mechanism is provided on the curing device body for driving the movable plates to approach or move away from the fixed plate. In this way, when curing the film, by using the equidistant gaps corresponding to the width of the photovoltaic panel solar cells between the fixed plate and the movable plates and between adjacent movable plates, during the process of the curing device irradiating the film with UV light, the film is irradiated through the gaps, forming multiple warp lines in a specific area of the film. The warp lines are pre-crosslinked after being irradiated by UV light, reducing the overall fluidity of the film, reducing the risk of solar cell offset during the lamination process of the module, reducing the use of positioning tapes at the same time, reducing energy consumption, and improving the product yield.

[0006] Preferably, the adjusting mechanism includes fixing pins fixed to the middle parts of both ends of the fixed plate and the movable plate. Two hinge plates are rotatably sleeved outside the fixing pins. The ends of adjacent hinge plates are hinged to each other. Both ends of the movable plate close to the curing equipment body are fixedly connected with guide rods that are slidably inserted through the curing equipment body. A cylinder is fixedly installed on the curing equipment body, and the output end of the cylinder is fixedly connected to the end of one of the guide rods. When the widths of different types of photovoltaic panel cells are different, the cooperation of the cylinder, the fixing pins fixed on the fixed plate and the movable plate, and the hinge plates installed on the fixing pins with adjacent hinge plates hinged to each other is used to adjust the size of the gap. When the output end of the cylinder drives the outermost movable plate to move away from the fixed plate, the gap becomes larger; conversely, when the output end of the cylinder drives the outermost movable plate to move closer to the fixed plate, the gap becomes smaller.

[0007] Preferably, the curing equipment body is fixedly connected with a guide sleeve sleeved outside the other guide rod.

[0008] Preferably, a plurality of balls are rotatably embedded at the top and bottom ends of both ends of the movable plate, and guide chutes for guiding the sliding of the balls are provided on the top wall and the bottom wall inside the guide frame plate.

[0009] Preferably, guide rollers for guiding the movement of the adhesive film are installed at both ends of the curing equipment body through bearing plates.

[0010] Preferably, a scale component for displaying the size of the gap is provided on the fixed plate and the movable plate close to the fixed plate. The scale component includes a scale plate and an indicating frame slidably sleeved on the scale plate. The scale plate is fixedly connected to the fixing pin on the fixed plate, and the indicating frame is fixedly connected to the fixing pin on the movable plate close to the fixed plate. By using the setting of the scale plate and the indicating frame, the initial value of the scale plate starts from the side of the fixed plate, and the side of the indicating frame and the side of the movable plate are located in the same vertical plane. Through the cooperation of the indicating frame and the scale plate, the size of the gap between the fixed plate and the movable plate can be indicated in real time, which is convenient for adjusting the distance between the movable plate and the fixed plate according to the cooperation of the scale plate and the indicating frame.

[0011] Compared with the prior art, the present utility model has the following advantages:

[0012] By using the equidistant gaps corresponding to the width of the photovoltaic panel cells between the fixed plate and the movable plate and between adjacent movable plates, during the process of the curing equipment irradiating the adhesive film with UV light, the adhesive film is irradiated through the gaps, so that multiple warp lines are formed in the specified area on the adhesive film. The warp lines are pre-crosslinked after being irradiated with UV light, reducing the overall fluidity of the adhesive film, reducing the risk of cell offset during the lamination process of the component, while reducing the use of positioning tape, reducing energy consumption, and improving the product yield.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 4 shown,

[0021] Embodiment 1

[0022] A kind of UV light curing equipment for photovoltaic panel glue film, comprising a curing equipment body. Inside the curing equipment body 1, guiding frame plates 7 are symmetrically and fixedly installed. In the middle of the guiding frame plates 7, a fixing plate 3 is fixedly inserted. Inside the guiding frame plates 7 and on both sides of the fixing plate 3, a plurality of movable plates 4 are arranged at equal intervals. A gap corresponding to the width of the photovoltaic panel cell is formed between the fixing plate 3 and the movable plates 4 and between adjacent movable plates 4;

[0023] During use, when the adhesive film needs to be cured, the equidistant gaps corresponding to the width of the photovoltaic panel cells between the fixed plate 3 and the movable plate 4 and between adjacent movable plates are utilized. During the process of the curing equipment irradiating the adhesive film with UV light, the adhesive film is irradiated through the gaps, forming multiple warp lines in a fixed area on the adhesive film. The warp lines are pre-crosslinked by UV light irradiation, reducing the overall fluidity of the adhesive film, reducing the risk of cell offset during the lamination process of the module, reducing the use of positioning tape, reducing energy consumption, and improving the product yield.

[0024] Embodiment 2

[0025] Different from Embodiment 1, (when the widths of different types of photovoltaic panel cells are different, there will be problems that the gaps are larger or smaller than the width of the cells).

[0026] When the widths of different types of photovoltaic panel cells are different, the output end of the cylinder 504 drives the guide rod 503 to move into the cylinder 504. The cylinder 504 drives the outermost movable plate 4 to move. The outer movable plate 4 drives the inner movable plate 4 to move away from the fixed plate 3 through the cooperation of the hinge plates 502 hinged to each other and the fixing pins 501, and then the gap becomes larger. The output end of the cylinder 504 drives the guide rod 503 to move out of the cylinder 504. The cylinder 504 drives the outermost movable plate 4 to move. The outer movable plate 4 drives the inner movable plate 4 to move closer to the fixed plate 3 through the cooperation of the hinge plates 502 hinged to each other and the fixing pins 501, and then the gap becomes smaller.

[0027] Specifically, a guide sleeve 505 sleeved outside the other guide rod 503 is fixedly connected to the curing equipment body 1; the cooperation of the guide sleeve 505 and the guide rod 503 can support and guide the movement of the side of the movable plate 4 connected to the hinge plates 502 hinged to each other through the fixing pins 501.

[0028] Furthermore, a plurality of balls 8 are rotatably embedded at the top and bottom ends of the movable plate 4, and guide chutes 701 for guiding and sliding the balls 8 are provided on the top wall and the bottom wall inside the guide frame plate 7; the friction between the movable plate 4 and the guide frame plate 7 can be reduced by the balls 8; meanwhile, it is convenient for the movable plate 4 to move on the guide frame plate 7.

[0029] Furthermore, both ends of the curing equipment body 1 are installed with guide rollers 2 for guiding the movement of the adhesive film through bearing plates, and it is convenient to straighten the adhesive film inside the curing equipment body 1 through the guide rollers 2.

[0030] Furthermore, a scale component 6 for displaying the size of the gap is provided on the fixed plate 3 and the movable plate 4 close to the fixed plate 3. The scale component 6 includes a scale plate 601 and an indicating frame 602 slidably sleeved on the scale plate 601. The scale plate 601 is fixedly connected to the fixing pin 501 on the fixed plate 3, and the indicating frame 602 is fixedly connected to the fixing pin 501 on the movable plate 4 close to the fixed plate 3; the initial value of the scale plate 601 starts from the side of the fixed plate 3, and the side of the indicating frame 602 and the movable plate 4 are located in the same vertical plane. The size of the gap between the fixed plate 3 and the movable plate 4 can be indicated in real time through the cooperation of the indicating frame 602 and the scale plate 601, which is convenient for adjusting the distance between the movable plate 4 and the fixed plate 3 according to the cooperation of the scale plate 601 and the indicating frame 602.
