Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel gap film pasting, and in particular to a photovoltaic panel gap film pasting rotary wind-guided film pasting assembly. Background Art

[0002] There will be gaps between the cell components of photovoltaic panels. In order to improve the luminous efficiency, current photovoltaic panels usually attach reflective film on the gaps between the cell components of photovoltaic panels. The attached reflective film will reflect the sunlight shining on the upper part to the inner side of the glass plate of the cell component, and then the sunlight will be further reflected from the inner side of the glass plate to the cell component, thereby improving the utilization rate of photovoltaic panels.

[0003] In order to realize the automatic attachment of reflective film to the gaps of photovoltaic panels, the patent publication number "CN117727818A" discloses "a kind of automatic film attachment device for reflective film in the gaps of photovoltaic cell components". The device realizes the automatic attachment of film to the numerous vertical and horizontal gaps of photovoltaic panels through multiple parallel film attachment components. In the process of film attachment, since the photovoltaic panel needs to pass through the lower part of the parallel film attachment components, the film attachment device is designed as a lifting structure in the device, and the attachment and separation of the gaps of photovoltaic panels are realized by directly controlling the lifting and lowering of the film attachment components. In the lifting structure, in order to facilitate and quickly realize the attachment action, a cylinder structure is usually used as a lifting component. Since the film attachment component needs to be directly lifted up and down, the lifting force during lifting is completely greater than the weight of the film attachment component. This not only makes the power used as the lifting component larger, but also makes the force of the film attachment component and the lifting component work downward together when pressing down, so that the overall attachment pressure is greatly increased. This not only consumes more power, but also reduces the service life of the equipment, and the excessive force is easy to damage the photovoltaic panel with glass as the back plate.

[0004] In addition, when attaching the reflective film to the gap position of the photovoltaic panel through the film sticking assembly, it is necessary to first cut off the laid reflective film, lift the film sticking assembly, and then after the lower photovoltaic panel is replaced, it is necessary to pull the reflective film forward from the cut end, and then extend the pulled reflective film end to the lower part of the film pressing wheel, and press the reflective film to the gap position of the photovoltaic panel through the film pressing wheel. In the existing design, the above patent and patent publication number "CN 116825869A" and "A Gap Reflective Film Laying Mechanism" respectively disclose a structure of a photovoltaic panel gap film assembly. Both of these film assemblies use a film pushing structure that pushes forward directly. After the reflective film is pushed forward, the film pushing mechanism needs to be withdrawn so that the end of the reflective film can be directly close to the lower part of the film pressing wheel to facilitate the heating and laminating of the lower part. However, since the reflective film is made of flexible material, it is difficult for the extended reflective film to maintain its shape. Therefore, the traditional film pushing mechanism can only push the reflective film a short distance. In this way, when the reflective film is pressed by the film pressing wheel in the next step, not only is the space small and difficult to operate, but the flexible reflective film is easy to roll up and bend. Therefore, it is difficult to ensure the neatness of the film strips when laminating during film pressing. Summary of the invention

[0005] In view of the above problems, the present invention provides a photovoltaic panel gap film-sticking rotating wind-guided film-sticking assembly, which adopts a rotating structure to achieve the contact and separation of the film-sticking structure and the photovoltaic panel gap position, and at the same time, through back blowing, it ensures that the reflective film can still maintain its position and shape after extending a large distance from the film-pushing end, thereby facilitating the heating of the lower film.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the photovoltaic panel gap film pasting rotary wind-guided film pasting assembly includes a connecting frame and a film pasting component, the connecting frame is equipped with a film guide component, the film pasting component includes a film pasting frame, the film pasting frame is equipped with a film guide pressing module through a telescopic structure, the reflective film to be attached is output from the front end of the film guide pressing module through the film guide component, and a film pressing wheel for pressing the reflective film is installed above the end of the reflective film extending out of the film guide pressing module; the film pasting component is hinged to the lower part of the connecting frame through the film pasting frame, and a film pasting telescopic part is hingedly installed on the connecting frame, and the telescopic end of the film pasting telescopic part is hinged to the front position of the film pasting frame; when the telescopic end of the film pasting telescopic part is extended, the film pressing wheel at the lower front end of the film guide pressing module rotates downward to the gap position of the photovoltaic panel to be filmed.

[0007] Preferably, the film-sticking telescopic member adopts a cylinder.

[0008] Preferably, a film-passing channel running straight through the film-guide pressing module is designed in the middle thereof, and the reflective film extends from the film-passing channel to the front end of the film-guide pressing module, and the front end of the film-guide pressing module is equipped with a limiting groove fixed on the film-sticking frame, and the reflective film extending out of the film-guide pressing module passes through the middle of the limiting groove, and a gap is provided between the reflective film and the lower part of the limiting groove, and a guide air outlet is designed at the lower part of the film-guide pressing module, which is opposite to the gap between the reflective film and the lower part of the limiting groove, and the guide wind blown out from the guide air outlet passes through the gap between the reflective film and the lower part of the limiting groove.

[0009] Preferably, the limiting groove comprises a bottom block at the bottom, and the upper part of the bottom block is designed with stoppers located on both sides of the reflective film.

[0010] Preferably, the film-guiding pressing module comprises a bottom plate, the upper portion of which is equipped with a T-shaped front plate and a square rear plate, and the pressing head of the film-guiding pressing module is telescopically mounted above the reflective film between the front plate and the rear plate.

[0011] Preferably, the film guiding and pressing module is assembled on the film laminating frame via a film pushing cylinder, and the extension and retraction direction of the film pushing cylinder is designed relative to the film feeding direction of the reflective film.

[0012] Preferably, the upper front end of the limit groove bottom block is designed as a lower shearing end, and the upper part of the limit groove is equipped with an upper shearing end that moves up and down, and the upper shearing end is assembled on the telescopic end of the shearing cylinder, and the cylinder body of the shearing cylinder is fixed to the front end of the film laminating frame. When the upper shearing end retracts upward with the telescopic end of the shearing cylinder, the upper shearing end and the lower shearing end open, and when the film guiding pressing module presses the reflective film and drives the reflective film forward through the film pushing structure, the front end of the reflective film passes through the middle of the opened upper shearing end and lower shearing end, and extends into the gap between the film pressing wheel and the photovoltaic panel.

[0013] Preferably, a hot air module is installed at the lower part of the film laminating frame, and the hot air outlet of the hot air module faces the lower part of the film pressing wheel in the working state.

[0014] Preferably, the front part of the film laminating frame is equipped with a film pressing wheel via a film pressing cylinder, and the telescopic end of the film pressing cylinder is directly above the film outlet position of the reflective film.

[0015] Preferably, the film sticking component is hinged to the lower part of the connecting frame through the middle position of the film sticking frame.

[0016] The beneficial effects of the present invention are:

[0017] The photovoltaic panel gap film-laminating rotary wind-guided film-laminating assembly is used on a gap film-laminating machine for photovoltaic panels. Specifically, multiple groups of the assembly are used in parallel on a mobile frame of the gap film-laminating machine. During specific use, the reflective film is output from the film pressing wheel at the bottom of the assembly. As the mobile frame moves, the film pressing wheel presses the reflective film tightly and attaches it to the gap position of the photovoltaic circuit board.

[0018] The component can independently complete the film guiding, film transporting, film feeding, pressing and hot-melting operations of the reflective film. The film pasting frame of the component is hinged to the lower part of the connecting frame where the film guiding component is assembled, and is hinged to the front position of the film pasting frame through the telescopic end of the film pasting telescopic member on the connecting frame. Due to the lever effect, the film pasting telescopic member only needs a little force to drive the film pasting frame equipped with the film guiding and pressing module to rotate, so that the film pasting position is close to the gap position of the lower photovoltaic panel; especially when the film pasting component is hinged to the lower part of the connecting frame through the middle position of the film pasting frame, most of the weight of the film guiding and pressing module together with the film pasting frame acts on the lower hinged position of the connecting frame; this not only greatly reduces the power of the film pasting telescopic member as the lifting power, but also because multiple of the components are used in parallel on the equipment, this greatly reduces the overall power consumption of the gap film pasting machine equipment as a whole, and can also effectively reduce the film pasting pressure pressed on the photovoltaic panel, thereby ensuring safety during film pasting.

[0019] When the component is working, the guide air is blown out through the lower guide air outlet of the film-guiding and pressing module, which is directly facing the gap between the reflective film and the lower part of the limiting groove, so that the reflective film extending to the front end of the film-guiding and pressing module can be kept under the film pressing wheel without the guidance of any fixing parts, which is convenient for heating and laminating at the lower part; at the same time, the back-blowing structure is simple and easy to implement, so that the reflective film will not be deformed by friction resistance when it is output forward, and the film pushing mechanism can push the reflective film to a farther distance, so that when the reflective film is pressed by the film pressing wheel in the next step, the action space is more sufficient, thereby ensuring the uniformity of the film size.

[0024] The present invention is further described below in conjunction with embodiments:

[0025] In this patent, the directional terms used are based on the Figure 1 The orientation or positional relationship of the figures shown is only for simplifying the description of the present application, rather than indicating a specific orientation that a device or component must have, and therefore should not be understood as a limitation on the present application.

[0026] In this embodiment, if Figure 1 and Figure 2 As shown, the photovoltaic panel gap film-sticking rotary wind-guided film-sticking assembly includes a connecting frame 1 and a film-sticking component. The connecting frame 1 is equipped with a film-guiding component 11. The connecting frame 1 uses a frame structure. The structure of the film-guiding component 11 is similar to that of traditional equipment and will not be repeated here. The general movement steps of the film-sticking component are similar to those of the traditional structure, but its specific connection structure is significantly different. Specifically, the film-sticking component includes a film-sticking frame 2, and a film-guiding pressing module 3 is installed on the film-sticking frame 2 through a telescopic structure. The film-sticking telescopic component 12 uses a cylinder. The reflective film 4 to be attached is output from the front end of the film guide pressing module 3 through the film guide component 11, and a film pressing wheel 5 for pressing the reflective film 4 is installed above the end of the reflective film 4 extending out of the film guide pressing module 3; the film pasting component is hinged to the lower part of the connecting frame 1 through the middle position of the film pasting frame 2, and a film pasting telescopic part 12 is hingedly installed on the connecting frame 1, and the telescopic end of the film pasting telescopic part 12 is hinged to the front position of the film pasting frame 2; when the telescopic end of the film pasting telescopic part 12 is extended, the film pressing wheel 5 at the lower front end of the film guide pressing module 3 rotates downward to the gap position of the photovoltaic panel to be filmed.

[0027] The photovoltaic panel gap film-laminating rotary wind-guided film-laminating assembly is used on a gap film-laminating machine for photovoltaic panels. Specifically, multiple groups of the assembly are used in parallel on a mobile frame of the gap film-laminating machine. When in use, the reflective film is output from the film pressing wheel 5 at the bottom of the assembly. As the mobile frame moves, the film pressing wheel 5 presses the reflective film tightly against the gap position of the photovoltaic circuit board.

[0028] The assembly can independently complete the film guiding, film transporting, film feeding, pressing and hot-melting operations of the reflective film 4. The film pasting frame 2 of the assembly is hinged to the lower part of the connecting frame 1 equipped with the film guiding component 11, and is hinged to the front position of the film pasting frame 2 through the telescopic end of the film pasting telescopic member 12 on the connecting frame 1. Due to the lever effect, the film pasting telescopic member 12 only needs a small amount of force to drive the film pasting frame 2 equipped with the film guiding and pressing module 3 to rotate, so that the film pasting position is close to the gap position of the lower photovoltaic panel; especially when the film pasting component is hinged to the lower part of the connecting frame 1 through the middle position of the film pasting frame 2, most of the weight of the film guiding and pressing module 3 together with the film pasting frame 2 acts on the lower hinged position of the connecting frame 1; this not only greatly reduces the power of the film pasting telescopic member 12 as the lifting power, but also because the assembly needs to be used in parallel on the equipment, which greatly reduces the overall power consumption of the gap film pasting machine equipment as a whole, and can also effectively reduce the film pasting pressure pressed on the photovoltaic panel, thereby ensuring the safety during film pasting.

[0029] In the specific design, such as Figure 1 , Figure 3 and Figure 4 As shown, the middle of the film guide pressing module 3 is designed with a film-passing channel that runs straightly from front to back, and the reflective film 4 passes through the film-passing channel and extends to the front end of the film guide pressing module 3. The front end of the film guide pressing module 3 is equipped with a limiting groove 6 fixed on the film sticking frame 2, and the reflective film 4 extending from the film guide pressing module 3 passes through the middle of the limiting groove 6, and there is a gap between the reflective film 4 and the lower part of the limiting groove 6; the limiting groove 6 includes a bottom block 61 at the bottom, and the upper part of the bottom block 61 is designed with blocks 62 located on both sides of the reflective film. At this time, the blocks 62 on both sides of the limiting groove 6 and the gap between the bottom block 61 and the reflective film 4 form an air guide channel. The lower part of the film guide pressing module 3 is designed with a guide air outlet 31 facing the gap between the reflective film 4 and the lower part of the limiting groove 6, and the guide wind blown out from the guide air outlet 31 passes through the gap between the reflective film 4 and the lower part of the limiting groove 6.

[0030] When the assembly is working, the guide air is blown out through the lower guide air outlet 31 of the film-guiding and pressing module 3 toward the gap position between the reflective film 4 and the lower part of the limiting groove 6, so that the reflective film 4 extending to the front end of the film-guiding and pressing module 3 can be kept under the film pressing wheel 5 without the guidance of any fixing parts, so as to facilitate the heating and laminating of the lower part; at the same time, the back-blowing structure can prevent the reflective film 4 from being deformed by the friction resistance when it is output forward, and can enable the film pushing mechanism to push the reflective film 4 to a farther distance, so that when the reflective film 4 is pressed by the film pressing wheel 5 in the next step, the action space is more sufficient, thereby ensuring the uniformity of the film size.

[0031] In the specific design, as shown in the figure, the film guide pressing module 3 includes a bottom plate 32, and the upper part of the bottom plate 32 is equipped with a T-shaped front plate 33 and a square rear plate 34. The pressing head 35 of the film guide pressing module 3 is telescopically mounted above the reflective film 4 between the front plate 33 and the rear plate 34. The front part of the bottom plate 32 is also designed to be T-shaped corresponding to the front plate 33, and the guide air outlet 31 is designed at the lower part of the bottom plate 32. In this embodiment, the guide air outlet 31 is designed in a horizontal plate body, so that the overall size is more compact. At the same time, the plane structure of the lower part of the bottom plate 32 can make the guide wind blown out of the guide air outlet 31 pass through the gap between the reflective film 4 and the lower part of the limiting groove 6.

[0032] like Figure 1 and Figure 2 As shown, the film guiding and pressing module 3 is assembled on the film laminating frame 2 through the film pushing cylinder 36, and the extension direction of the film pushing cylinder 36 is designed relative to the film feeding direction of the reflective film 4. The lower part of the film laminating frame 2 is assembled with a hot air module 7, and the hot air outlet 71 of the hot air module 7 is directly opposite to the lower part of the film pressing wheel 5 in the working state.

[0033] When the components of this embodiment are working, the lower guide air outlet 31 of the film-guiding pressing module 3 blows out a guide airflow, and at this time the pressing head 35 is pressed on the luminous film 4, and then the film-pushing cylinder 36 pushes the film-guiding pressing module 3 toward the film-sticking position. After reaching the set position, the pressing head 35 is released, and the film-pushing cylinder 36 drives the film-guiding pressing module 3 to retract. At this time, due to the guide airflow of the guide air outlet 31, the advancing reflective film 4 remains suspended and extends to the lower part of the film-sticking wheel 5 in the direction of film-sticking. At this time, the hot air flow blown out from the hot flow outlet 71 of the hot air module 7 heats and melts the reflective film 4 at the lower part of the film-sticking wheel 5. At this time, the film-sticking wheel 5 is pressed down to the gap position of the photovoltaic panel together with the reflective film 4 to achieve hot melt bonding.

[0034] In this embodiment, the design of the shear structure is different from the traditional structure, such as Figure 1 and Figure 3As shown, the front end upper part of the bottom block 61 of the limit groove 6 is designed as a lower shear end 611, and the upper part of the limit groove 6 is equipped with an upper shear end 63 that moves up and down. The upper shear end 63 is assembled on the telescopic end of the shear cylinder 64, and the cylinder body of the shear cylinder 64 is fixed to the front end of the film-sticking frame 2. When the upper shear end 63 retracts upward with the telescopic end of the shear cylinder 64, the upper shear end 63 and the lower shear end 611 are opened. When the film-guiding pressing module 3 presses the reflective film 4 and drives the reflective film 4 to move forward through the film-pushing structure, the front end of the reflective film 4 passes through the middle of the opened upper shear end 63 and the lower shear end 611 and extends into the gap between the film pressing wheel 5 and the photovoltaic panel. In this structure, the lower shear end 611 is relatively stationary, and the upper shear end 6 is driven downward by the shear cylinder 64 to achieve cutting of the reflective film 4. The cutting structure directly uses the front end of the bottom block 61 as the lower shear end 611, and the overall structure is more compact, which increases the operating space of the film-sticking position.

[0035] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the front part of the film-sticking frame 2 is equipped with a film-sticking wheel 5 through a film-sticking cylinder 51, and the telescopic end of the film-sticking cylinder 51 is directly above the film-out position of the reflective film 4. At this time, the film-sticking telescopic member 12 is mainly used to adjust the approximate position of the film-guiding pressing module 3 and the film-sticking wheel 5 relative to the gap position of the photovoltaic panel, and then the film-sticking cylinder 51 is used to adjust the final film-sticking position. This design makes the entire operation process more precise. At the same time, the pressing force of the film-sticking wheel 5 on the reflective film 4 during film-sticking is jointly determined by the film-sticking cylinder 51 and the film-sticking telescopic member 12, making it easier to adjust the film-sticking force.

[0036] The above embodiments are only preferred modes of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
