Description

Technical Field

[0001] This application relates to the field of photovoltaic production equipment manufacturing technology, and in particular to a hot-heating mechanism and its film-applying device. Background Technology

[0002] Studies have found that attaching insulating film around photovoltaic modules can effectively reduce the required creepage distance. However, in actual application, due to limited working space, a side-by-side application method is commonly used. Specifically, photovoltaic modules typically consist of a top surface, a bottom surface, and four sides, with four insulating films attached to each side. To ensure complete coverage on each side, the width of the insulating film is often slightly larger than the actual width of the module's side. The portion exceeding the side width needs to extend and be attached to the edge areas of the adjacent top and bottom surfaces of the module. Furthermore, to ensure a sealed corner, the length of the insulating film is also slightly longer than the side length, with one end of the film wrapping around the corner and attaching to the end of an adjacent side. This results in material overlap of the insulating film strips from adjacent sides at the four corners of the module.

[0003] To address the overlapping of insulating films in corner areas and ensure a proper seal, current methods often rely on manual heating using equipment such as hot air guns and industrial irons to fuse the stacked insulating films together. However, this manual approach has significant limitations: it is inefficient, difficult to match the pace of modern production lines, and struggles to guarantee consistent heat curing. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a hot-pressing mechanism and its film-applying device to solve the problems of low hot-pressing efficiency and difficulty in ensuring consistent heat curing.

[0005] In a first aspect, this application provides a hot-heating mechanism, comprising: a base plate, a first adjustment component, a second adjustment component, and a hot-heating component. The hot-heating component is mounted on the drive end of the second adjustment component, and the second adjustment component is mounted on the drive end of the first adjustment component. The first adjustment component is fixedly mounted on the base plate. The base plate can be driven to move along the edge of a photovoltaic module. The first adjustment component is configured to drive the second adjustment component and the hot-heating component to move along a first horizontal direction, and the second adjustment component is configured to drive the hot-heating component to move along a second horizontal direction. The first horizontal direction is perpendicular to the edge of the photovoltaic module, and the second horizontal direction is perpendicular to the first horizontal direction. The heating element is positioned along the angle bisector of the length of the photovoltaic module with the film already applied. The heating element includes a first mounting frame, a first driving member, and a first heating element, an intermediate heating element, and a second heating element sequentially arranged on the first mounting frame in a vertical direction. The first driving member is configured to drive the first heating element and the second heating element to move towards each other in a vertical direction, such that the first heating element is in contact with the upper surface of the photovoltaic module and the second heating element is in contact with the lower surface of the photovoltaic module. The intermediate heating element has intersecting first and second heating surfaces on the portion facing the photovoltaic module, which are in contact with the two adjacent sides of the photovoltaic module that have been covered with insulating film.

[0006] Based on the aforementioned hot-pressing mechanism, according to the work sequence, the base plate drives the entire hot-pressing mechanism to move to the target corner of the photovoltaic module. Subsequently, the first adjustment component drives the second adjustment component and the hot-pressing component to move along the first horizontal direction; simultaneously, the base plate continues to drive the hot-pressing mechanism to move along the edge of the photovoltaic module until the working range of the hot-pressing component covers the target corner. During this process, through the synergistic action of the first adjustment component and the base plate, the first heating surface and the second heating surface are respectively attached to the two sides corresponding to the target corner. Next, the first driving component drives the first heating component and the second heating component to move towards each other in the vertical direction, so that the first heating component is attached to the upper surface of the photovoltaic module and the second heating component is attached to the lower surface of the photovoltaic module. Compared with the prior art, this application, by setting up a hot-pressing mechanism, realizes the simultaneous automated heating of the adjacent two sides and the upper and lower surfaces of the target corner of the photovoltaic module, which not only improves the sealing efficiency of the insulating film, but also ensures the consistency of the thermosetting effect.

[0007] Optionally, the first adjustment component includes a first slide rail, a second mounting bracket, and a drive cylinder. The first slide rail is fixedly mounted on the base plate, the second mounting bracket is slidably mounted on the first slide rail, and the drive cylinder is configured to drive the second mounting bracket to move along a first horizontal direction. The second adjustment component is mounted on the second mounting bracket.

[0008] Based on the first adjustment component mentioned above, the second mounting bracket is driven by the drive cylinder to move along the first slide rail, thereby smoothly bringing the second adjustment component closer to the photovoltaic module, which facilitates the subsequent hot-heating operation.

[0009] Optionally, the second adjustment component includes a third mounting bracket and a second drive member, the third mounting bracket being slidably disposed on the second mounting bracket, and the second drive member being configured to drive the third mounting bracket to move along a second horizontal direction; the first mounting bracket is mounted on the third mounting bracket.

[0010] Optionally, the third mounting bracket is provided with an abutment structure, and the second mounting bracket is provided with a stop structure. The abutment structure and the stop structure are arranged sequentially along the second horizontal direction to determine the limit position of the movement stroke of the third mounting bracket.

[0011] Based on the aforementioned contact and stop structures, excessive movement of the third mounting bracket can be avoided, thereby preventing damage to the photovoltaic modules.

[0012] Optionally, the hot-pressing mechanism also includes a buffer component, and the second adjustment component is elastically mounted on the first adjustment component along the length of the applied film via the buffer component.

[0013] Based on the aforementioned buffer component, when the second adjustment component drives the heating element to contact the photovoltaic module, if a collision occurs between the two, some of the collision energy can be dissipated through the buffer component, thereby preventing damage to the photovoltaic module.

[0014] Optionally, the buffer assembly includes a limiting block, an elastic base, a guide rail arranged along the length of the applied film, and a guide rail slider that slides with the guide rail; the second adjustment assembly is connected to the guide rail slider, one end of the guide rail slider along the length of the guide rail is connected to the elastic part of the elastic base, and the other end abuts against the limiting block.

[0015] Optionally, the heating element also includes a first positioning block and a second positioning block, both mounted on the buffer component. The side of the first positioning block that contacts the photovoltaic module is parallel to the first heating surface, and the side of the second positioning block that contacts the photovoltaic module is parallel to the second heating surface. When the corresponding sides of the first and second positioning blocks are respectively attached to the two adjacent sides of the photovoltaic module, the first heating surface and the second heating surface can move along the second horizontal direction under the drive of the second adjustment component and respectively attach to the two adjacent sides of the photovoltaic module.

[0016] Based on the first and second positioning blocks mentioned above, the contact area between the hot-heating component and the photovoltaic component can be increased, thereby improving the stability of the photovoltaic component during the hot-heating operation.

[0017] Optionally, both the first heating element and the second heating element are slidably disposed on the first mounting bracket, and both can be locked and unlocked at a preset position on the first mounting bracket; one of the first heating element and the second heating element is fixedly connected to the driving end of the first driving element, and the other is fixedly connected to the fixed end of the first driving element.

[0018] Optionally, the preset angle between the first heating surface and the second heating surface is a right angle; and / or, the first heating surface and the second heating surface are smoothly connected by an arc surface.

[0019] In a second aspect, this application provides a film-applying device, including the hot-pressing mechanism as described above and a film-applying mechanism disposed on a base plate. The film-applying mechanism is disposed in front of the hot-pressing mechanism and is used to apply an insulating film to the side of a photovoltaic module.

[0020] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0023] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0024] Currently, when processing overlapping insulating films at corners and edges, most methods rely on manual heating using equipment such as hot air guns and industrial irons to locally heat the overlapping areas, melting the multiple layers of insulating film into a single unit. However, this method suffers from low efficiency and difficulty in ensuring consistent sealing after heat treatment.

[0025] Therefore, this application creatively proposes a hot-pressing mechanism and a film-applying device. The hot-pressing mechanism includes a base plate, a first adjustment component, a second adjustment component, and a hot-pressing component. The film-applying device includes the hot-pressing mechanism and a film-applying mechanism located in front of the hot-pressing mechanism. First, after the film-applying mechanism completes the film application to the photovoltaic module, the base plate drives the hot-pressing mechanism to move as a whole to the target corner of the photovoltaic module according to the work sequence. Subsequently, the first adjustment component drives the second adjustment component and the hot-pressing component to move along a first horizontal direction; simultaneously, the base plate continues to drive the hot-pressing mechanism to move along the edge of the photovoltaic module until the working range of the hot-pressing component covers the target corner. During this process, through the synergistic effect of the first adjustment component and the base plate, the first heating surface and the second heating surface are respectively attached to the two sides corresponding to the target corner. Next, the first driving component drives the first heating component and the second heating component to move towards each other in the vertical direction, so that the first heating component is attached to the upper surface of the photovoltaic module and the second heating component is attached to the lower surface of the photovoltaic module. Compared with existing technologies, this application achieves automated heating of the adjacent two sides and the upper and lower surfaces of the target corner of the photovoltaic module by setting up a spot heating mechanism, which not only improves the sealing efficiency of the insulating film, but also ensures the consistency of the thermosetting effect.

[0026] The present application will be specifically described below through specific embodiments.

[0027] Example 1 Reference Figures 1 to 3 As shown in the figure, this application embodiment provides a spot-heating mechanism, which includes a base plate 1, a first adjustment component 2, a second adjustment component 3, and a spot-heating component 4. The spot-heating component 4 is mounted on the driving end of the second adjustment component 3, and the second adjustment component 3 is mounted on the driving end of the first adjustment component 2. The first adjustment component 2 is fixedly mounted on the base plate 1. The base plate 1 can be driven to move along the edge of the photovoltaic module. The first adjustment component 2 is configured to drive the second adjustment component 3 and the spot-heating component 4 to move along a first horizontal direction, and the second adjustment component 3 is configured to drive the spot-heating component 4 to move along a second horizontal direction. The first horizontal direction is perpendicular to the edge of the photovoltaic module, and the second horizontal direction is the angle bisector of the first horizontal direction and the length direction of the film-coated surface. The heating element 4 includes a first mounting frame 41, a first driving member 42, and a first heating element 43, an intermediate heating element 44, and a second heating element 45 arranged sequentially on the first mounting frame 41 in a vertical direction. The first driving member 42 is configured to drive the first heating element 43 and the second heating element 45 to move towards each other in a vertical direction, so that the first heating element 43 is in contact with the upper surface of the photovoltaic module and the second heating element 45 is in contact with the lower surface of the photovoltaic module. The intermediate heating element 44 has an intersecting first heating surface 441 and a second heating surface 442 on the part facing the photovoltaic module, so as to be in contact with the two adjacent sides of the photovoltaic module that have been covered with insulating film.

[0028] It should be noted that, referring to Figure 2 As shown, X is defined as the first horizontal direction, and Y is the length direction of the photovoltaic module with the film applied. Based on the geometric principle of angle bisectors, the X, Y, and A directions are all in the same plane. If the X and Y directions are regarded as the two sides of the angle, then the A direction (the second horizontal direction) is the direction of the angle bisector of the included angle.

[0029] In some examples, the first drive member 42 may be a linear drive mechanism such as a cylinder or an electric cylinder. To ensure that the drive direction moves along a vertical trajectory, the first drive member 42 may be installed in a vertical position.

[0030] In some examples, the first heating element 43, the second heating element 45, and the intermediate heating element 44 may integrate resistance wires as heat sources or be designed as cavity structures for the circulation of heat-conducting fluids to achieve efficient heat transfer.

[0031] Furthermore, considering that photovoltaic modules are typically rectangular plate structures, in this embodiment, the preset angle between the first heating surface 441 and the second heating surface 442 can be set as a right angle. This design ensures that the right-angled surface formed by the first heating surface 441 and the second heating surface 442 can closely fit with the right-angled surfaces formed by the adjacent two sides of the photovoltaic module, ensuring heating uniformity. If the actual angle between the adjacent two sides of the photovoltaic module is not a right angle, this preset angle can also be adjusted accordingly to adapt to different geometric shapes of the module's corners. For example, if the corners of the photovoltaic module are smoothly transitioned arc surfaces, the intersection of the first heating surface 441 and the second heating surface 442 can be connected by an arc surface, which can also match the shape of the photovoltaic module's corners to achieve the heating purpose.

[0032] Specifically, firstly, according to the work sequence, the base plate 1 drives the entire heating mechanism to move to the target corner of the photovoltaic module. Then, the first adjustment component 2 drives the second adjustment component 3 and the heating component 4 to move along the first horizontal direction; subsequently, the base plate 1 drives the heating mechanism to move along the edge of the photovoltaic module until the working area of ​​the heating component 4 covers the target corner. During this process, through the coordinated action of the first adjustment component 2 and the base plate 1, the first heating surface 441 and the second heating surface 442 are respectively attached to the two sides corresponding to the target corner. Next, the first driving component 42 drives the first heating component 43 and the second heating component 45 to move towards each other in the vertical direction, so that the first heating component 43 is attached to the upper surface of the photovoltaic module and the second heating component 45 is attached to the lower surface of the photovoltaic module. Compared with the prior art, this application, by setting up the heating mechanism, achieves simultaneous automated heating of the adjacent two sides and the upper and lower surfaces of the target corner of the photovoltaic module, which not only improves the sealing efficiency of the insulating film but also ensures the consistency of the thermosetting effect.

[0033] Furthermore, in some examples, refer to Figure 1 and Figure 2 As shown, the first adjustment component 2 includes a first slide rail 21, a second mounting bracket 22 and a drive cylinder 23. The first slide rail 21 is fixedly mounted on the base plate 1, the second mounting bracket 22 is slidably mounted on the first slide rail 21, and the drive cylinder 23 is configured to drive the second mounting bracket 22 to move along the first horizontal direction; the second adjustment component 3 is mounted on the second mounting bracket 22.

[0034] In this embodiment, the first slide rail 21 is arranged along the first horizontal direction so that the second mounting bracket 22 can move linearly along the first horizontal direction, thereby improving the stability of the movement of the second mounting bracket 22 and ensuring smooth movement along a straight line.

[0035] Furthermore, in some examples, refer to Figure 2 As shown, the second adjustment component 3 includes a third mounting bracket 31 and a second driving member 32. The third mounting bracket 31 is slidably disposed on the second mounting bracket 22, and the second driving member 32 is configured to drive the third mounting bracket 31 to move along the second horizontal direction; the first mounting bracket 41 is mounted on the third mounting bracket 31.

[0036] In this embodiment, the second driving component 32 can be a linear driving mechanism such as a cylinder or an electric cylinder. To ensure that its driving direction is consistent with the second horizontal direction, the second driving component 32 should be arranged along the second horizontal direction. By assembling the first mounting bracket 41 onto the third mounting bracket 31, the second driving component 32 can drive the entire hot-heating component 4 to move along the second horizontal direction with the help of the third mounting bracket 31, thereby enabling the hot-heating component 4 to move closer to or further away from the target corner of the photovoltaic module.

[0037] To prevent the third mounting bracket 31 from moving beyond its limits, some limiting structures can be set to restrict the movement distance of the third mounting bracket 31. This is provided as an example, not a limitation. Figure 2 As shown, the third mounting frame 31 is provided with an abutment structure 311, and the second mounting frame 22 is provided with a stop structure 221. The abutment structure 311 and the stop structure 221 are arranged sequentially along the second horizontal direction to prevent the third mounting frame 31 from moving excessively and damaging the photovoltaic module.

[0038] In some examples, the abutment structure 311 is roughly cylindrical, and the stop structure 221 is cylindrical like a cap, with an opening at one end that extends inward to form a receiving cavity. When the second driving member 32 pushes the third mounting bracket 31 to move, the abutment structure 311 enters the receiving cavity of the stop structure 221. By preset the depth of the receiving cavity, the maximum stroke of the abutment structure 311 can be precisely limited, thereby controlling the movement distance of the third mounting bracket 31 (and the connected heat exchanger 4), effectively preventing the heat exchanger 4 from colliding with the photovoltaic module due to excessive displacement. Of course, the abutment structure 311 can also adopt other regular or irregular shapes such as prisms, and the stop structure 221 can be designed accordingly as a thin plate or a suitable cavity, the core of which is to achieve effective abutment with the abutment structure 311 at a preset position.

[0039] Furthermore, in some examples, an elastic structure (such as a spring or rubber layer) can be added to the side of the abutment structure 311 that contacts the stop structure 221. This can act as a buffer when the two come into contact, absorbing collision energy and helping to improve the stability of the third mounting bracket 31 when it stops. Alternatively, the stop structure 221 can use common buffers that utilize elasticity or air pressure (such as air springs or plunger-type pneumatic dampers) to achieve the same buffering and limiting effect on the abutment structure 311.

[0040] In some examples, refer to Figure 2 and Figure 3 As shown, the hot-pressing mechanism also includes a buffer component 5, and the second adjustment component 3 is elastically mounted on the first adjustment component 2 along the length of the applied film via the buffer component 5.

[0041] It should be noted that, for better adhesion during ironing, please refer to... Figure 2As shown, in this embodiment, the first heating surface 441 is perpendicular to the first horizontal direction, while the second heating surface 442 is parallel to the vertical plane containing the first horizontal direction. To optimize the hot-pressing process, it is usually necessary to designate one side of the target corner of the photovoltaic module as the priority surface so that the middle heating plate can be quickly aligned with the target corner of the photovoltaic module. In this embodiment, the side parallel to the first heating surface 441 among the two adjacent sides corresponding to the target corner can be selected as the priority surface. First, the base plate 1 moves along the edge of the photovoltaic module, driving the entire hot-pressing mechanism to move along the horizontal direction (i.e., the Y direction) parallel to the priority surface, thereby reducing the distance between the second heating surface 442 and the side of the target corner corresponding to it, until the distance between the first heating surface 441 and the priority surface, and between the second heating surface 442 and the non-priority surfaces among the two sides of the target corner, are equal. Then, through the adjustment of the second adjustment component 3, the intermediate heating element 44 is driven to approach the target corner of the photovoltaic module along the second horizontal direction until the first heating surface 441 is in contact with the preferred surface, and the second heating surface 442 is simultaneously in contact with the non-preferred surfaces on both sides of the target corner, thereby improving the heating efficiency.

[0042] By setting the buffer component 5, an effective buffer can be provided when the heating component 4 comes into contact with the photovoltaic module, absorbing the collision energy and ensuring that the intermediate heating component 44 moves more smoothly when it is in contact with the target corner of the photovoltaic module.

[0043] See, as an example rather than a limitation. Figure 3 As shown, the buffer assembly 5 includes a limiting block 51, an elastic base 52, a guide rail 53 arranged along the length of the applied film, and a guide rail slider 54 that slides with the guide rail 53. The second adjustment assembly 3 is connected to the guide rail slider 54. When the guide rail slider 54 moves along the length of the guide rail 53, one end can abut against the elastic part 521 of the elastic base 52, and the other end can abut against the limiting block 51. The elastic part 521 will cause the guide rail slider 54 to abut against the limiting block 51.

[0044] In this embodiment, the elastic part 521 of the elastic base 52 is a cylindrical compression spring.

[0045] Specifically, when the second heating surface 442 collides with the photovoltaic module (preferred surface), the elastic part 521 will be squeezed, thereby dissipating some of the energy generated by the collision of the photovoltaic module and greatly reducing the probability of damage to the photovoltaic module.

[0046] Furthermore, in some examples, in order to determine the target corner positions of the photovoltaic module so that the heating mechanism can accurately contact each face of the photovoltaic module's corners, reference is made. Figure 2 and Figure 3As shown, the hot-heating component 4 also includes a first positioning block 46 and a second positioning block 47, both mounted on the buffer component 5. The side of the first positioning block 46 that contacts the photovoltaic module is parallel to the first heating surface 441, and the side of the second positioning block 47 that contacts the photovoltaic module is parallel to the second heating surface 442. When the corresponding surfaces of the first positioning block 46 and the second positioning block 47 are respectively attached to the two adjacent sides of the photovoltaic module, the first heating surface 441 and the second heating surface 442 are parallel to the two adjacent sides of the photovoltaic module, which facilitates the second driving member 32 to drive the hot-heating component 4 to move along the second horizontal direction and smoothly contact the target corner of the photovoltaic module that is about to be heated.

[0047] It should be noted that when the corresponding surfaces of the first positioning block 46 and the second positioning block 47 are respectively attached to the two adjacent sides of the photovoltaic module, the first heating surface 441 and the second heating surface 442 can move along the second horizontal direction under the drive of the second adjustment component 3 so as to be attached to the two adjacent sides of the photovoltaic module respectively.

[0048] In some examples, the first heating surface 441 and the second heating surface 442 may not be simultaneously attached to the target corner of the photovoltaic module. For instance, at least one of the first heating surface 441 and the second heating surface 442 may be elastically connected to the main body of the intermediate heating element 44 (e.g., via a spring). This allows the attached surface to be compressed when one of the first heating surface 441 and the second heating surface 442 is attached to the target corner of the photovoltaic module, while the other surface is not. This allows the other surface to continue to approach the target corner, ultimately achieving attachment of the two sides corresponding to the target corner.

[0049] In this embodiment, in order to improve the heating efficiency and ensure the insulation film covers the target corners, the horizontal distance between the first heating surface 441 and the first positioning block 46 and the second heating surface 442 and the second positioning block 47 are set to be equal, and the connection between the first heating surface 441 and the second heating surface 442 is set to be completely in contact with the target corners, so as to fully heat all positions of the insulation film.

[0050] When the corresponding surfaces of the first positioning block 46 and the second positioning block 47 are respectively attached to the two adjacent sides of the photovoltaic module, the distances between the first heating surface 441 and the preferred surface and between the second heating surface 442 and the non-preferred surfaces of the two adjacent sides of the photovoltaic module are equal. At this time, by adjusting the second driving member 32, the two heating surfaces of the intermediate heating member 44 can be simultaneously attached to the target corner.

[0051] In this embodiment, refer to Figure 2 and Figure 3As shown, the buffer assembly 5 also includes a fourth mounting bracket 55, through which the second adjustment assembly 3 is connected to the guide rail slider 54. Simultaneously, the first positioning block 46 and the second positioning block 47 are also directly mounted on the fourth mounting bracket 55. At this time, the elastic portion 521 of the elastic base 52 applies elasticity to the fourth mounting bracket 55, causing the fourth mounting bracket 55 to abut against the limiting block 51.

[0052] To enhance the structural strength and precise guidance path required by the addition of the fourth mounting bracket 55, and to improve organizational convenience, a second slide rail 56 is provided on the fourth mounting bracket 55. The second mounting bracket 22 is slidably mounted on the second slide rail 56, and the second drive component 32 is also fixed to the fourth mounting bracket 55. Correspondingly, the stop structure 221 needs to be simultaneously adjusted to the fourth mounting bracket 55 to ensure effective cooperation with the abutment structure 311 installed on the second mounting bracket 22. In addition, to further optimize overall rigidity, the first mounting bracket 41 can be directly fixed to the fourth mounting bracket 55 to form a stable composite support structure. The setting of the first positioning block 46 and the second positioning block 47 helps to expand the effective contact area between the heating mechanism and the photovoltaic module, thereby enhancing the overall stability of the photovoltaic module during the heating operation.

[0053] To further reduce the impact damage that the positioning operation may cause to the surface of the photovoltaic module, a buffer layer can be added to the working surfaces of the first positioning block 46 and the second positioning block 47 that contact the photovoltaic module. This buffer layer can absorb and disperse the local stress at the moment of contact, providing good protection.

[0054] In some examples, the first heating element 43 and the second heating element 45 are both slidably disposed on the first mounting bracket 41, and both can be locked and unlocked at a preset position on the first mounting bracket 41; one of the first heating element 43 and the second heating element 45 is fixedly connected to the driving end of the first driving element 42, and the other is fixedly connected to the fixed end of the first driving element 42.

[0055] In this embodiment, a third slide rail 411 with dual sliders is provided on the first mounting bracket 41. The first heating element 43 and the second heating element 45 are respectively mounted on the two independent sliders of the slide rail. By controlling the movement of each slider on the third slide rail 411, precise stopping control of the first and second heating elements 45 at preset positions on the first mounting bracket 41 can be achieved. It should be noted that, in order to make the overall structure of the heating assembly 4 compact, this third slide rail 411 generally only has basic locking and unlocking functions; the movement of the slider after unlocking must be reliably driven by external force (such as a single-acting cylinder), rather than relying solely on its own weight.

[0056] The first driving component 42 adopts a single-acting cylinder, which has a simple structure and compact size, helping to reduce the overall size of the hot-heating assembly 4. In the specific control process, the required relative movement can be achieved by keeping one slider in a sliding state and the other slider in a fixed state. In this configuration, the fixed end (cylinder body) of the first driving component 42 can also move relative to its driving end (drive shaft).

[0057] Example 2 Corresponding to Embodiment 1 above, this application also provides a film-applying device, including a heat-pressing mechanism and a film-applying mechanism disposed on a base plate 1. The film-applying mechanism is disposed in front of the heat-pressing mechanism and is used to apply insulating film to the side of the photovoltaic module. Through the cooperation of the film-applying mechanism and the heat-pressing mechanism, the film-applying efficiency of the photovoltaic module can be improved, ensuring the sealing effect of the corners and the consistency of heat curing.
