In existing technologies, high-transmittance glass is used for the back glass, with multiple reflective films applied to its surface at specified locations. Reflective film is a material used in photovoltaic power generation equipment; its main function is to reflect sunlight and improve the photoelectric conversion efficiency of the PV module. Manual film application is inefficient and cannot guarantee the application effect. To achieve automated film application and improve efficiency and effect, this invention provides a film application head that, driven by an external drive device, can automatically apply the reflective film.

[0042] This utility model provides a glass film applicator head, and the embodiments of this utility model will be described below with reference to the accompanying drawings.

[0043] In the description of the embodiments of this utility model, it should be understood that the terms "top," "bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, an embodiment of this utility model provides a glass film applicator head, including a film-laying mechanism 30, a film-feeding mechanism 40, a film-pressing mechanism 50, and a film-cutting mechanism 60. The film-laying mechanism 30, film-feeding mechanism 40, film-pressing mechanism 50, and film-cutting mechanism 60 are connected to a head connector frame 10. The film-laying mechanism 30 is used to lay and transmit the film 90 to the film-feeding mechanism 40. The film-feeding mechanism 40 is used to convey the end of the film 90 to the underside of the film-pressing mechanism 50. The film-pressing mechanism 50 is used to apply the film 90 to the glass surface. The film-cutting mechanism 60 is used to cut the film 90. The head connector frame 10 is connected to an external drive device, which can drive the film applicator head to move horizontally and vertically to complete the application of the film 90 to the glass surface.

[0045] The film feeding mechanism 30 includes a support roller 31, multiple fixed guide wheels 32, and movable guide wheels 33. The support roller 31 supports the film roll, the multiple fixed guide wheels 32 are located at the bottom of the support roller 31 and are used to transmit the film 90 to the film feeding mechanism 40, and the movable guide wheels 33 are located between the fixed guide wheels 32. During the transmission of the film 90, the movable guide wheels 33 can be driven to move up and down.

[0046] In this embodiment, a support roller 31 is installed on the top of the head connector 10, on which a roll of film material is wound. A feeding motor 34 is connected to the support roller 31 to drive the support roller 31 to rotate and feed the film 90. A guide roller 35 is installed below the support roller 31. Below the guide roller 35, multiple fixed guide wheels 32 are rotatably connected via a vertically arranged mounting plate 20. The mounting plate 20 is fixed to the bottom of the head connector 10. When the film 90 is guided by the guide roller 35 and the uppermost fixed guide wheel 32, the film 90 needs to be twisted according to the installation direction of the guide roller 35 and the fixed guide wheel 32. A movable guide wheel 33 is installed between the two fixed guide wheels 32 in the middle position. An elongated hole is opened on the mounting plate 20 corresponding to the movement trajectory of the movable guide wheel 33, and the movable guide wheel 33 can move up and down along the elongated hole. As the diameter of the membrane roll decreases during unloading, if the support roller 31 maintains the same rotation speed, the membrane 90 may become loose at the beginning and tight at the end during transmission. Therefore, it is necessary to adjust the rotation speed of the support roller 31 to ensure more stable unloading of the membrane 90. To prevent the membrane 90 from becoming too loose or too tight during transmission, which could affect normal transmission, a movable guide wheel 33 is provided. When the membrane 90 becomes loose or tight during transmission, it will cause the movable guide wheel 33 to move downward or upward. By detecting the height of the movable guide wheel 33, the rotation speed of the support roller 31 can be adjusted. During the process of the membrane 90 becoming loose or tight, the movable guide wheel 33 also plays a tensioning role, ensuring stable transmission of the membrane 90.

[0047] To ensure the movement trajectory of the movable guide wheel 33, a vertical guide rail 36 is installed on the other side of the mounting plate 20, and the movable guide wheel 33 slides through the elongated hole and is slidably connected to the vertical guide rail 36. To ensure the balance of the movable guide wheel 33, a counterweight 37 is installed at the end of the movable guide wheel 33 away from the vertical guide rail 36. To detect the height of the movable guide wheel 33, an upper limit sensor 38 and a lower limit sensor 39 are fixed above and below the vertical guide rail 36. When the movable guide wheel 33 rises to the upper limit sensor 38, the membrane body 90 becomes too tight, at which point the rotation speed of the support roller 31 is increased to speed up the membrane release. When the movable guide wheel 33 descends to the lower limit sensor 39, the membrane body 90 becomes too loose, at which point the rotation speed of the support roller 31 is decreased to slow down the membrane release.

[0048] To facilitate the conduction of the membrane 90, the entire film feeding mechanism 40 is inclined, including a base 41 and a guide plate 42 arranged opposite each other. One end of the guide plate 42 extends out of the base 41 near the film pressing mechanism 50. A clamping cylinder 43 is located above the guide plate 42, fixedly connected to the base 41, and perpendicular to the base 41 and guide plate 42. A through hole is provided on the mounting plate 20 relative to the film feeding mechanism 40. The side of the base 41 near the through hole passes through the through hole and connects to the film feeding cylinder 44 fixed on the other side of the mounting plate 20. A groove is provided on the side of the guide plate 42 near the base 41, forming a through-slot gap with the base 41. The membrane 90 can pass through this gap and fit with it. A through hole is provided on the guide plate 42 relative to the clamping cylinder 43, allowing the clamping cylinder 43 to pass through the through hole and press against the membrane 90 to clamp it. The clamping cylinder 43 clamps the membrane body 90, while the membrane placement mechanism 30 places and conducts the membrane body 90. The extending membrane delivery cylinder 44 can move the membrane body 90 closer to the pressing mechanism 50, and convey the membrane body 90 to the bottom of the pressing mechanism 50. After the membrane delivery is completed, the clamping cylinder 43 shortens and no longer clamps the membrane body 90, and the membrane delivery cylinder 44 shortens and resets, so that the membrane body 90 can be conducted normally in the gap.

[0049] Because the membrane 90 is relatively soft, its end tends to droop after passing through the gap between the guide plate 42 and the base 41, making it difficult to place under the pressing mechanism 50. An air inlet 45 is provided on one side of the base 41. Air is blown into the gap between the guide plate 42 and the base 41 through the air inlet 45. When the air is blown out from the end near the pressing mechanism 50, the membrane 90 can be placed along the guide plate 42 without its end drooping, making it easier for the film feeding mechanism 40 to deliver the end of the membrane 90 to the pressing mechanism 50.

[0050] Preferred, such as Figure 1 , Figure 3 and Figure 4 As shown, a heating mechanism 70 is provided below the film feeding mechanism 40. A hot air outlet 71 is provided at one end of the heating mechanism 70 near the film pressing mechanism 50. During the application process, the film 90 is heated, making the application of the film 90 more secure. In this embodiment, the heating mechanism 70 is fixed to the bottom of the mounting plate 20 and includes a heating cavity 72. A hot air outlet 71 is fixed at one end of the heating cavity 72 near the film pressing mechanism 50, and an air inlet 73 is fixed at the other end.

[0051] Preferably, in order to facilitate the placement of the membrane 90 along the guide plate 42, a guide block 74 is fixed at the upper part of the hot air outlet 71. The top of the guide block 74 is an inclined guide surface. The guide surface is set opposite to the end of the guide plate 42 that extends out of the base 41. A gap is formed between the guide surface and the guide plate 42. The membrane 90 can pass through the gap and fit with the gap.

[0052] Specifically, the film pressing mechanism 50 includes a film pressing cylinder 51 and a film pressing roller 52. The film pressing roller 52 is mounted on the film pressing cylinder 51, and the film pressing cylinder 51 can drive the film pressing roller 52 to move up and down. In this embodiment, the film pressing cylinder 51 is vertically fixed to the bottom of the mounting plate 20. The film pressing roller 52 is rotatably connected to the movable end of the film pressing cylinder 51. When the film feeding mechanism 40 delivers the end of the film body 90 to below the film pressing roller 52, the film pressing cylinder 51 drives the film pressing roller 52 to move downward, pressing the film body 90 onto the glass surface. The external drive device drives the film applicator head to move along the application trajectory of the film body 90, so that the film body 90 is laid along the application trajectory. During the laying process, the film pressing roller 52 rolls along the film body 90, applying the film body 90 onto the glass surface.

[0053] Specifically, the film cutting mechanism 60 includes a moving cylinder 61, on which a shearing cylinder 62 is mounted. The shearing cylinder 62 can move closer to or away from the film body 90. The shearing cylinder 62 is equipped with scissors 63, which can open and close. In this embodiment, the moving cylinder 61 is fixed to the side of the mounting plate 20 where the film feeding mechanism 40 and the film pressing mechanism 50 are not installed. The movable end of the moving cylinder 61 is fixed to the vertically arranged shearing cylinder 62 via a connecting bracket 64. Scissors 63 are mounted at the bottom of the shearing cylinder 62. Figure 3 and Figure 4 As shown, the lower blade of the scissors 63 is fixed to the bottom of the connecting bracket 64, and the upper blade of the scissors 63 is connected to the movable end of the scissors 63 cylinder, which can drive the upper blade of the scissors 63 to move up and down, thereby opening and closing the scissors 63.

[0054] Preferred, such as Figure 3 and Figure 4 As shown, to prevent the film 90 from tilting during the film application process, an anti-deviation frame 80 is provided on the side of the film pressing mechanism 50 near the film cutting mechanism 60. The bottom of the anti-deviation frame 80 has an anti-deviation groove 81 through which the film 90 can pass. In this embodiment, the anti-deviation frame 80 is fixed to the bottom of the mounting plate 20. Based on the conduction direction of the film 90, an inclined anti-deviation groove 81 is provided at the bottom of the anti-deviation frame 80. During the film application process, the anti-deviation groove 81 can limit the movement of the film 90.

[0055] Workflow: The external drive unit moves the film applicator head to the starting position and height for film application. The film placement mechanism 30 places and transmits the film 90. Simultaneously, the film feeding mechanism 40 passes the end of the film 90 through the anti-deviation groove 81 and conveys it to the underside of the pressing mechanism 50. The pressing mechanism 50 presses the film 90 onto the glass surface. The clamping cylinder 43 shortens to release the film 90, and the feeding cylinder 44 shortens to reset. The external drive unit moves the film applicator head along the application trajectory to complete the laying of the entire film 90. During the laying process, the pressing roller 52 rolls along the film 90, adhering the film 90 to the glass surface. At the same time, the hot air outlet 71 of the heating mechanism 70 heats the film 90, making the film 90 adhere more firmly. During the film application process, the anti-deviation groove 81 can limit and prevent the film 90 from deviating. After the membrane 90 is applied, the clamping cylinder 43 extends through the guide plate 42 to clamp the membrane 90, and the film cutting mechanism 60 cuts the membrane 90.

[0056] The advantages and positive effects of the present invention are:

[0057] 1. By implementing film application, feeding, pressing, and cutting processes, automatic glass film application is achieved, which improves work efficiency, enhances the firmness of film application, ensures the film application effect, and improves product quality.

[0058] 2. The film-laying mechanism ensures the stability of film laying by setting movable guide wheels, preventing it from being too tight or too loose.

[0059] 3. The membrane feeding mechanism ensures the conveying direction of the membrane by setting guide plates and air inlets.

[0060] 4. The film pressing mechanism uses pressing rollers to press the film, ensuring the film's application effect.

[0061] 5. The heating mechanism further ensures the firmness of the film application by heating the film.

[0062] 6. By setting anti-deviation grooves, the film body is prevented from deviating during the application process, further improving the accuracy of the application.

All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
