[0044] Therefore, how to overcome the above problems has become one of the technical problems that need to be solved urgently at this stage.

[0045] In view of this, the utility model provides a photovoltaic film laminating device, which uses a small-volume device to perform film laminating through electromagnetic induction heating, so as to improve the problems of large-scale film laminating machines having large volume and low heat conversion efficiency.

[0046] The following is a detailed description with reference to the accompanying drawings and specific embodiments.

[0047] Figure 1 The schematic diagram of a photovoltaic film laminating device provided in the embodiment of the present application is shown in FIG. Figure 1 ; The present application provides a photovoltaic film-sticking device 100, which includes a first support base 10 and a second support base 20 that are relatively arranged, a film-sticking device 30 and an electromagnetic induction heating device 40; the first support base 10 and the second support base 20 are located on the same side of the film-sticking device 30, and the electromagnetic induction heating device 40 is located on the side of the first support base 10 and the second support base 20 that are away from the film-sticking device 30; when the photovoltaic film-sticking device 100 is in a working state, the member to be film-sticked 50 is clamped between the first support base 10 and the second support base 20, and the member to be film-sticked 50 is located between the film-sticking device 30 and the electromagnetic induction heating device 40.

[0048] Specifically, the present application provides a photovoltaic film-sticking device 100, including a first supporting base 10 and a second supporting base 20, a film-sticking device 30 and an electromagnetic induction heating device 40, which are arranged relatively. The first supporting base 10 and the second supporting base 20 are used to support the film-sticking device 30 on one hand, and to fix the piece to be film-sticked 50 on the other hand; the film-sticking device 30 and the electromagnetic induction heating device 40 are respectively located on both sides of the piece to be film-sticked 50, and are heated by electromagnetic induction heating, so that the film strip is attached to the surface of the piece to be film-sticked 50. The present application heats by electromagnetic induction, which has higher safety performance and higher heat conversion efficiency than a heating air gun, which is conducive to reducing energy waste, thereby helping to improve film-sticking efficiency. At the same time, the photovoltaic film-sticking device 100 provided by the utility model is light and compact, easy to move, and is conducive to increasing the use scenarios of the photovoltaic film-sticking device 100, thereby making the application of the photovoltaic film-sticking device 100 more extensive.

[0049] It should be noted that the photovoltaic film-sticking equipment 100 provided in the drawings of the present application is for illustration only and does not represent its actual structure and size.

[0050] Please continue to refer to Figure 1 The present application provides an optional implementation scheme, in which the film sticking device 30 includes a track light rod 31, a slider 32 and a roller 33; the track light rod 31 is fixedly connected to one side of the first support base 10 and the second support base 20; the slider 32 is located on the side of the plane where the track light rod 31 is located away from the first support base 10, and the slider 32 is slidably connected to the track light rod 31; the roller 33 is located on the side of the slider 32 close to the plane where the track light rod 31 is located, and the roller 33 is connected to the slider 32; the electromagnetic induction heating device 40 is located on the side of the roller 33 away from the slider 32.

[0051] Specifically, in the present embodiment, the film pasting device 30 includes a track light rod 31, a slider 32 and a roller 33. The track light rod 31 is fixed on the first support base 10 and the second support base 20. The track light rod 31 provides a sliding track for the slider 32. The slider 32 and the track light rod 31 are slidably connected. The roller 33 is fixed on the slider 32. The electromagnetic induction heating device 40 is arranged on the side of the roller 33 away from the slider 32. When the photovoltaic film pasting equipment 100 is in working state, the film pasting member 50 is fixed between the film pasting device 30 and the electromagnetic induction heating device 40 through the first support base 10 and the second support base 20, and the film tape is adhered to the surface of the film pasting member 50 through the roller 33 by electromagnetic induction heating.

[0052] It can be understood that the present application uses electromagnetic induction heating to apply film. Alternating current generates a magnetic field through the coil 41 in the electromagnetic induction heating device 40. The magnetic lines of force in the magnetic field pass through the bottom of the roller 33 to generate eddy currents. The roller 33 is heated by magnetic heat. The roller 33 acts on the film strip to make the film strip adhere to the surface of the piece 50 to be applied with film. Applying film using electromagnetic induction heating is beneficial to uniform heating of the film strip, improving heat conversion efficiency, and reducing energy waste, thereby helping to improve film application efficiency and reduce production costs. At the same time, the photovoltaic film application equipment 100 provided by the utility model is light and compact, easy to move, and helps to increase the use scenarios of the photovoltaic film application equipment 100, thereby making the photovoltaic film application equipment 100 more widely used.

[0053] Please note that, please refer to Figure 1 , along the first direction D1, by moving the slider 32 on the track polished rod 31, the film is pasted at different positions in the first direction D1. Optionally, when the gap film pasting device is in working state, the moving speed of the slider 32 is v, 150mm / s≤v≤250mm / s; when the moving speed v of the slider 32 is <150mm / s, the moving speed of the slider 32 is too slow, which may cause the local temperature of the piece 50 to be film-pasted to be too high, thereby causing damage to the piece 50 to be film-pasted; when the moving speed v of the slider 32 is >250mm / s, the moving speed of the slider 32 is too fast, which is not conducive to the film tape being pasted on the surface of the piece 50 to be film-pasted; therefore, the present application sets the moving speed of the slider 32 to v is set to 150mm / s≤v≤250mm / s; the present application provides an optional implementation manner that the moving speed of the slider 32 is v=180mm / s; the present application provides another optional implementation manner that the moving speed of the slider 32 is v=200mm / s; the present application provides another optional implementation manner that the moving speed of the slider 32 is v=220mm / s; the present application provides another optional implementation manner that the moving speed v of the slider 32 is set to 160mm / s≤v≤210mm / s; the present application provides another optional implementation manner that the moving speed v of the slider 32 is set to 190mm / s≤v≤240mm / s.

[0054] Please continue to refer to Figure 1 Along the second direction D2, by adjusting the relative positions between the piece to be film-laminated 50 and the first support base 10 and the second support base 20, film lamination at different positions in the second direction D2 is achieved.

[0055] It should also be noted that in the field of photovoltaic modules, the film-mounted part 50 can be a cover plate or a back plate of a photovoltaic module. Common materials for the cover plate include glass, and common materials for the back plate include glass or a composite film composed of multiple layers of polymer films, which include a fluorine-containing film, a PET film (polyethylene terephthalate film) and an EVA adhesive layer (polyethylene-polyvinyl acetate copolymer), etc.

[0056] Please continue to refer to Figure 1 The present application provides an optional implementation scheme in which the film sticking device 30 also includes a laser irradiation pen 34; the laser irradiation pen 34 is located on the side of the slider 32 close to the track light rod 31 and is fixedly connected to the slider 32; the light emitting direction of the laser irradiation pen 34 is parallel to the movement direction of the roller 33.

[0057] Specifically, in the present embodiment, the film pasting device 30 is provided with a laser irradiation pen 34, and the light emitting direction of the laser irradiation pen 34 is parallel to the movement direction of the roller 33. During the film pasting process, the laser irradiation pen 34 illuminates a horizontal line, and the slider 32 moves along the track light rod 31 based on the horizontal line illuminated by the laser irradiation pen 34. Such a setting is conducive to the accurate positioning of the film strip, thereby improving the film pasting accuracy of the photovoltaic film pasting equipment 100.

[0058] Please continue to refer to Figure 1 The present application provides an optional implementation manner in which the film sticking device 30 further includes a film roll 35 , and the film roll 35 is located on a side of the slider 32 away from the plane where the track polished rod 31 is located, and the film roll 35 is connected to the slider 32 .

[0059] Specifically, in the present embodiment, the film pasting device 30 is further provided with a film roll 35, and the film roll 35 is arranged on the slider 32, and a film tape is arranged in the film roll 35, that is, the film tape is arranged on the slider 32. Such arrangement is conducive to the rapid material taking of the photovoltaic film pasting equipment 100, thereby improving the film pasting efficiency of the photovoltaic film pasting equipment 100.

[0060] Please continue to refer to Figure 1 The present application provides an optional implementation scheme in which the slider 32 includes a through hole 321, and the through hole 321 penetrates the slider 32 along the thickness direction of the slider 32; when the photovoltaic film pasting equipment 100 is in a working state, the film tape in the film roll 35 passes through the through hole 321 and is fixed between the roller 33 and the piece to be pasted 50.

[0061] Specifically, in the present embodiment, the film pasting device 30 includes a film roll 35, and the slider 32 includes a through hole 321. When the photovoltaic film pasting equipment 100 is in working condition, the film tape in the film roll 35 passes through the through hole 321, and the film tape is placed on the surface of the member to be pasted 50 through the roller 33. The slider 32 drives the roller 33 to move slowly, and the roller 33 generates heat due to electromagnetic induction, thereby pasting the film tape to the surface of the member to be pasted 50. In this way, the film roll 35 is arranged on one side of the slider 32, and the film tape in the film roll 35 passes through the through hole 321 and is fixed between the roller 33 and the member to be pasted 50. When pasting the film, it is only necessary to push the slider 32 along the track light rod 31, which is conducive to improving the ease of use of the photovoltaic film pasting equipment 100, and also conducive to improving the degree of automation of the photovoltaic film pasting equipment 100.

[0062] Please continue to refer to Figure 1 The present application provides an optional implementation scheme in which the slider 32 includes a bottom plate 322 and a handle 323. The bottom plate 322 is parallel to the plane where the track light rod 31 is located. The bottom plate 322 is slidably connected to the track light rod 31. The handle 323 is located on the side of the bottom plate 322 away from the plane where the track light rod 31 is located, and the handle 323 is fixed on the bottom plate 322.

[0063] Specifically, in this embodiment, the slider 32 includes a base plate 322 and a handle 323, wherein the base plate 322 is parallel to the plane where the track light rod 31 is located, and is slidably connected to the track light rod 31, and the handle 323 is arranged on the side of the base plate 322 away from the plane where the track light rod 31 is located. During the use of the photovoltaic film pasting device 100, the handle 323 is pushed to apply the film, which further helps to improve the convenience of using the photovoltaic film pasting device 100.

[0064] It should be noted that the drawings of the present application only provide an optional implementation for clearly illustrating the relative positions of the base plate 322 and the handle 323 , but the present application is not limited thereto and does not specifically limit the specific structure, size, etc. of the handle 323 .

[0065] Please continue to refer to Figure 1 Optionally, the material of the roller 33 includes at least one of iron and stainless steel.

[0066] Specifically, the photovoltaic film-sticking device 100 of the present application is applied by electromagnetic induction heating. The alternating current generates a magnetic field through the coil 41 in the electromagnetic induction heating device 40. The magnetic lines of force in the magnetic field pass through the bottom of the roller 33 to generate eddy currents. The roller 33 is heated by magnetic heat. The roller 33 acts on the film strip. When the roller 33 is made of iron or stainless steel, the heating effect of the roller 33 is better, which is conducive to improving the film-sticking efficiency and film-sticking effect of the photovoltaic film-sticking device 100. The present application provides an optional implementation that the material of the roller 33 includes iron; the present application provides another optional implementation that the material of the roller 33 includes stainless steel.

[0067] Figure 2 FIG. 1 is a schematic diagram of another photovoltaic film-mounting device provided in an embodiment of the present application. Please refer to FIG. Figure 2 The present application provides an optional implementation manner, which further includes an S-shaped conveyor belt 60, which is respectively connected to the film laminating device 30 and the electromagnetic induction heating device 40, and the electromagnetic induction heating device 40 moves in the same direction as the film laminating device 30 moves.

[0068] Specifically, in the present embodiment, the photovoltaic film pasting equipment 100 also includes an S-shaped conveyor belt 60, and the film pasting device 30 and the electromagnetic induction heating device 40 are both connected to the S-shaped conveyor belt 60. When the photovoltaic film pasting equipment 100 is in working state, the slider 32 moves along the track light rod 31, and the electromagnetic induction heating device 40 moves in the same direction at the same time under the drive of the S-shaped conveyor belt 60. In this way, the slider 32 and the electromagnetic induction heating device 40 move at the same time, which is beneficial to improve the electromagnetic induction effect between the slider 32 and the electromagnetic induction heating device 40, which is not only beneficial to improve the film pasting effect of the photovoltaic film pasting equipment 100, but also beneficial to improve the degree of automation of the photovoltaic film pasting equipment 100, and further beneficial to improve the film pasting efficiency of the photovoltaic film pasting equipment 100.

[0069] It should be noted that this application is only Figure 2 The example shown is for illustration only and does not represent the actual structure, nor is it limited to this. Please continue to refer to Figure 2 The S-shaped conveyor belt 60 includes a sliding belt 61 and two pulleys 62. The two pulleys 62 are fixedly connected to the first support base 10 and the second support base 20 respectively. The sliding belt 61 is bent through the pulleys 62 to form an S shape. When the slider 32 slides along the track polished rod 31, the electromagnetic induction heating device 40 also slides in the same direction.

[0070] It is also necessary to explain that please continue to refer to Figure 2 , Figure 2An electromagnetic induction sliding light rod 63 is also provided, which is fixedly connected to the first support base 10 and the second support base 20, and is located on the side of the first support base 10 and the second support base 20 away from the track light rod 31. The electromagnetic induction device 40 is slidably connected to the electromagnetic induction sliding light rod 63. Such a setting is more conducive to the electromagnetic induction device 40 moving in the same direction as the slider 32 slides. When the photovoltaic film pasting device 100 is provided with the electromagnetic induction sliding light rod 63, the actual structure of the first support base 10 and the second support base 20 can also be designed according to actual conditions, and this application does not make specific limitations and is not limited to this.

[0071] Please continue to refer to Figure 1 Optionally, when the photovoltaic film pasting equipment 100 is in working state, the plane where the film-pasted member 50 is located is parallel to the plane where the electromagnetic induction heating device 40 is located, and the minimum distance between the film-pasted member 50 and the electromagnetic induction heating device 40 is L, 5mm≤L≤50mm.

[0072] Specifically, the photovoltaic film pasting equipment 100 provided in the present application performs film pasting by electromagnetic induction heating. An alternating current generates a magnetic field through the coil 41 in the electromagnetic induction heating device 40. The magnetic lines of force in the magnetic field pass through the bottom of the roller 33 to generate eddy currents. The roller 33 is heated by magnetic heat generation. The roller 33 acts on the film tape, thereby achieving the film tape being adhered to the surface of the piece to be pasted 50. In order to facilitate the improvement of the electromagnetic induction effect between the roller 33 and the electromagnetic induction heating device 40, the present application sets the minimum distance L between the piece to be pasted 50 and the electromagnetic induction heating device 40 to 5mm≤L≤50mm. When the minimum distance L between the piece to be pasted 50 and the electromagnetic induction heating device 40 is <5mm or L>50mm, it is not conducive to the roller 33 being affected by electromagnetic induction. Therefore, the minimum distance L between the piece to be pasted 50 and the electromagnetic induction heating device 40 is set to 5mm≤L≤50mm. The present application provides an optional implementation manner, in which the minimum distance L between the member to be film-attached 50 and the electromagnetic induction heating device 40 is 10 mm; the present application provides another optional implementation manner, in which the minimum distance L between the member to be film-attached 50 and the electromagnetic induction heating device 40 is 30 mm; the present application provides yet another optional implementation manner, in which the minimum distance L between the member to be film-attached 50 and the electromagnetic induction heating device 40 is 45 mm; the present application provides yet another optional implementation manner, in which the minimum distance L between the member to be film-attached 50 and the electromagnetic induction heating device 40 is set to 8 mm ≤ L ≤ 35 mm; the present application provides yet another optional implementation manner, in which the minimum distance L between the member to be film-attached 50 and the electromagnetic induction heating device 40 is set to 20 mm ≤ L ≤ 40 mm.

[0073] Please continue to refer to Figure 1The present application provides an optional implementation manner in which the electromagnetic induction heating device 40 includes a coil 41, a temperature regulating module and a power regulating module, and the power regulating module is electrically connected to the coil 41 and the temperature regulating module respectively.

[0074] Specifically, in this embodiment, the electromagnetic induction heating device 40 includes a coil 41, a temperature adjustment module and a power adjustment module, wherein the coil 41 is used to generate a magnetic field, and the magnetic lines of force in the magnetic field pass through the roller 33 to generate eddy currents, thereby utilizing magnetic heat generation to heat the roller 33.

[0075] The temperature regulation module is used to adjust the heating temperature T of the electromagnetic induction device. Optionally, the heating temperature of the electromagnetic induction heating device 40 is 290℃≤T≤310℃. Within this temperature range, it is beneficial for the film tape to be attached to the surface of the piece to be attached 50, and it is also beneficial for reducing the damage caused to the piece to be attached 50 and the photovoltaic film attaching equipment 100 due to excessively high temperature; when the heating temperature T of the electromagnetic induction heating device 40 is <290℃, the heating temperature is too low, which is not conducive to the film tape being attached to the surface of the piece to be attached 50; when the heating temperature T of the electromagnetic induction heating device 40 is >310℃, the excessively high temperature may cause damage to the piece to be attached 50 and the photovoltaic film attaching equipment 100; therefore, the present application sets the heating temperature T of the electromagnetic induction heating device 40 to 290℃≤T≤310℃. The present application provides an optional implementation manner that the heating temperature T of the electromagnetic induction heating device 40 is 295°C; the present application provides another optional implementation manner that the heating temperature T of the electromagnetic induction heating device 40 is 300°C; the present application provides yet another optional implementation manner that the heating temperature T of the electromagnetic induction heating device 40 is 305°C; the present application provides yet another optional implementation manner that the heating temperature T of the electromagnetic induction heating device 40 is set to 292°C≤T≤302°C; the present application provides yet another optional implementation manner that the heating temperature T of the electromagnetic induction heating device 40 is set to 298°C≤T≤308°C.

[0076] It should be noted that the temperature adjustment module may also include a temperature sensor, which can monitor changes in the heating temperature and adjust the temperature more timely, thereby helping to improve the film application effect, but the present application is not limited to this.

[0077] The power regulation module is used to adjust the power P of the electromagnetic induction device. Optionally, the power of the electromagnetic induction heating device 40 is 2000W≤P≤3000W.
