Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy photovoltaic frame processing technology, and in particular to a device for uniformly applying film to aluminum alloy photovoltaic frames. Background Technology
[0002] The role of the protective film on the aluminum alloy photovoltaic frame is mainly reflected in the following aspects: By covering the aluminum alloy surface, the protective film can effectively resist the erosion of natural environments such as ultraviolet rays, rain, and wind and sand, and prevent oxidation corrosion and mechanical damage. After the film is combined with the frame, it can improve the sealing performance of the module, prevent moisture, dust and other substances from entering the internal structure, and reduce the risk of PID effect (potential-induced degradation).
[0003] A photovoltaic module production film applicator with application number CN202223192254.7 is described. With the cooperation of a chute, a slide bar, a sliding plate and a positioning mechanism, the height of the pressure roller can be easily positioned, so that the pressure roller can press and stick the film onto the surface of aluminum frame at different heights, making film application convenient.
[0004] However, the above-mentioned patent has the following defects in actual operation: it uses a threaded rod to push the limiting plate to move horizontally and limit the side of the aluminum alloy frame. However, the premise for the limiting effect is that the side wall of the aluminum alloy frame is in contact with the outer wall of the limiting plate. After the contact is made, a certain friction will be generated. The transmission method is a conveyor belt. Under the action of the friction of the limiting plate, the aluminum alloy frame may stop on the conveyor belt. In addition, only a single pressure roller is used for pressing, which can easily lead to uneven film. Utility Model Content

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The embodiment of this utility model provides a uniform film application device for an aluminum alloy photovoltaic frame, comprising: a conveyor belt 1, side plates 2 fixedly installed on both sides of the outer wall of the conveyor belt 1, a limit component 3 commonly provided on the two side plates 2, and a film application component 4 commonly provided on the two side plates 2; the film application component 4 includes two film application plates 41, the two film application plates 41 are respectively located on the top of the two side plates 2, and a film application roller 42 is movably installed on one side of each of the two film application plates 41, and an installation groove 43 is opened on each of the two film application plates 41, a pressure roller 44 is movably installed in the cavity of the installation groove 43, a connecting component 45 is installed on the other side of the film application plate 41, a transmission plate 46 is installed on the connecting component 45, and a power component 47 is commonly provided on the two transmission plates 46.
[0031] Specifically, firstly, the upper film roller 42 is installed and connected to the external film. Then, the aluminum alloy photovoltaic frame to be coated is placed flat on the surface of the conveyor belt 1, and the conveyor belt 1 is directly driven, so that the conveyor belt 1 drives the aluminum alloy photovoltaic frame to move horizontally. During the movement of the aluminum alloy photovoltaic frame, the movement of the aluminum alloy photovoltaic frame is limited by the limiting component 3. After the aluminum alloy photovoltaic frame moves to the appropriate position, the power component 47 drives the transmission plate 46 to deflect. The transmission plate 46 drives the connecting component 45 to move. The connecting component 45 drives the upper film plate 41 to move. The upper film plate 41 drives the upper film roller 42 to move to adhere to the outer wall of the aluminum alloy photovoltaic frame, so that the upper film roller 42 directly adheres the film to the outer wall of the aluminum alloy photovoltaic frame, thus completing the coating operation.
[0032] In this embodiment, as Figures 2-3 As shown; the limiting component 3 includes four stepper motors 32, which are located at the bottom of the two side plates 2 near the left and right sides respectively. The top output ends of the four stepper motors 32 are all fixedly connected to rotating rods 33. The top of the rotating rods 33 passes through the side plate 2 and is rotatably connected to the side plate 2. A movable plate 34 is fixedly installed through the top of the rotating rods 33. An abutment roller 35 is movably installed on one side of the movable plate 34.
[0033] Specifically, a stepper motor 32 can be driven to rotate a rotating rod 33, which in turn rotates a movable plate 34. The movable plate 34 then moves a contact roller 35 to the outer wall to adhere to the aluminum alloy photovoltaic frame, thereby limiting the movement trajectory of the aluminum alloy photovoltaic frame and preventing it from shifting during movement. This ensures the stability of subsequent film application operations.
[0034] In this embodiment, as Figures 2-3 As shown; each of the four stepper motors 32 has a base 31 fixedly connected to its bottom, and the four bases 31 are respectively fixedly connected to the bottom of the two side plates 2.
[0035] Specifically, the base 31 is used to fix the stepper motor 32 to the side plate 2, which further improves the stability of the stepper motor 32 during subsequent operation.
[0036] In this embodiment, as Figure 5 As shown; the connecting component 45 includes a movable part 451, which is fixedly connected to the outer wall of the upper membrane plate 41. A fixing part 452 is fixedly connected to the outer wall of the transmission plate 46. A round shaft 453 is fixedly installed through the movable part 451. Both ends of the round shaft 453 pass through the outer wall of the fixing part 452 and are rotatably connected to the outer wall of the fixing part 452.
[0037] Specifically, when the transmission plate 46 moves, it drives the fixed part 452 to move. The fixed part 452 drives the movable part 451 to move through the round shaft 453. The movable part 451 drives the upper film plate 41 and the upper film roller 42 to move to fit against the outer wall of the aluminum alloy photovoltaic frame. If the transmission plate 46 continues to move, the fixed part 452 and the movable part 451 gradually make arc movements around the round shaft 453, so that the upper film plate 41 gradually moves from the inclined state to the horizontal state. This makes the upper film roller 42 and the pressure roller 44 on the upper film plate 41 fit against the outer wall of the aluminum alloy photovoltaic frame. The upper film roller 42 realizes the film application operation, while the pressure roller 44 realizes the pressing of the upper film to ensure that the upper film is uniform and flat.
[0038] In this embodiment, as Figure 5 As shown; two torsion springs 454 are movably mounted on the outer wall of the round shaft 453, and the two ends of the two torsion springs 454 are fixedly connected to the inner wall of the fixed part 452 and the outer wall of the movable part 451, respectively.
[0039] Specifically, the torsion spring 454 provides a certain resistance between the moving part 451 and the fixed part 452, so that when the transmission plate 46 moves, it directly drives the upper diaphragm plate 41 to move. When the transmission plate 46 is reset, the upper diaphragm plate 41 and other components will be reset under the elastic force of the torsion spring 454.
[0040] In this embodiment, as Figures 2-4 As shown; the power assembly 47 includes an electric push rod 475, which is located at the bottom of the conveyor belt 1. The telescopic end of the electric push rod 475 is fixedly connected to a horizontal plate 474. Racks 473 are fixedly connected to both sides of the outer wall of the horizontal plate 474. Gears 472 mesh with the outer walls of the two racks 473. Vertical shafts 471 are fixedly connected to the top of the two gears 472. The top ends of the two vertical shafts 471 pass through the corresponding side plate 2 and the transmission plate 46 respectively, and are rotatably connected to the two side plates 2 respectively. The two vertical shafts 471 are fixedly connected to the two transmission plates 46 respectively.
[0041] Specifically, when the transmission plate 46 is moved, the electric push rod 475 can be driven, which in turn drives the horizontal plate 474 to move. The horizontal plate 474 drives the two racks 473 to move. The two racks 473 drive the two gears 472 to rotate. The two gears 472 drive the two vertical shafts 471 to rotate. The two vertical shafts 471 drive the two transmission plates 46 to perform arc-shaped movements.
[0042] In this embodiment, as Figures 2-4 As shown; the other end of the electric push rod 475 is fixedly connected to a fixing plate 476, which is fixedly installed at the bottom of the conveyor belt 1.
[0043] Specifically, the fixing plate 476 is used to fix the electric push rod 475 to the bottom of the conveyor belt 1, so as to ensure the stability of the electric push rod 475 during subsequent operation.
[0044] In this embodiment, as Figures 2-4 As shown, two limiting rods 477 are movably installed through the horizontal plate 474. One end of each limiting rod 477 is fixedly connected to a limiting block 478, and the other end of each limiting rod 477 is fixedly connected to the outer wall of the fixing plate 476.
[0045] Specifically, during the horizontal movement of the horizontal plate 474, it will be limited by the limiting rod 477, and the setting of the limiting block 478 can prevent the horizontal plate 474 from disengaging from the limiting rod 477.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
