Description
Technical Field
[0001] This application relates to the field of photovoltaic equipment, specifically a photovoltaic module edge sealing device. Background Technology
[0002] Photovoltaic modules are typically made by laminating a first cover plate, a first encapsulant film, a cell string, a second encapsulant film, and a second cover plate in sequence. After lamination, the photovoltaic modules also need to be fitted with a frame around them.
[0003] To prevent short circuits, a large creepage distance is required between the frame and the solar cells inside the photovoltaic module. However, a large creepage distance inevitably affects the luminous efficiency per unit area of the photovoltaic module. To solve this problem, an insulating film can be applied to the four edges of the photovoltaic module before installing the frame, effectively insulating and sealing the photovoltaic module. After the frame is assembled onto the photovoltaic module, the insulating film provides insulation between the frame and the module, thus significantly reducing the creepage distance and ultimately improving the luminous efficiency per unit area of the photovoltaic module.
[0004] Existing edge-sealing equipment typically uses pressure rollers to seal the edges of the photovoltaic module, as disclosed in patents such as CN208970534U, CN209374413U, and CN220078111U. However, using pressure rollers for edge sealing easily leads to the formation of numerous large-diameter air bubbles between the insulating film and the upper and lower surfaces of the photovoltaic module, failing to meet module quality requirements. Summary of the Invention
[0005] To address the aforementioned technical problems, this application provides a photovoltaic module edge-sealing device, the detailed technical solution of which is as follows: A photovoltaic module edge sealing device is used to attach an insulating film to the four edges of a photovoltaic module. The photovoltaic module edge sealing device includes: The support mechanism is used to support the photovoltaic modules to be coated with film; Four film-applying mechanisms are arranged around the top four sides of the support mechanism, and are used to apply insulating film to the four edges of the photovoltaic modules on the support mechanism. The film application mechanism includes a translation drive mechanism, a mounting frame, a film application section, and a heating section. The mounting frame is connected to the movable end of the translation drive mechanism. The film application section and the heating section are both mounted on the mounting frame. The heating section includes a first heating plate and a second heating plate arranged vertically opposite each other. The first heating plate and the second heating plate can move closer to each other or further away from each other. A heating channel that can accommodate one edge of the photovoltaic module is formed between the first heating plate and the second heating plate. The translation drive mechanism is used to drive the mounting bracket to move toward the corresponding edge of the photovoltaic module, so that the edge of the photovoltaic module enters the corresponding heating channel. The film-applying part is used to apply the insulating film to the corresponding edge of the photovoltaic module, so that the insulating film is bonded to the upper surface, side surface and lower surface of the edge of the photovoltaic module. The first heating plate and the second heating plate are configured to press the corresponding edge of the photovoltaic module from the upper and lower sides to squeeze and heat the insulating film pasted on the upper and lower surfaces of the edge of the photovoltaic module.
[0006] By arranging four film-applying mechanisms around the four sides of the support structure, film can be applied to the four edges of the photovoltaic module. Specifically, each film-applying mechanism includes a film-applying section and a heating section. The film-applying section applies an insulating film to one edge of the photovoltaic module, ensuring adhesion between the insulating film and the upper, side, and lower surfaces of the photovoltaic module edge. Then, the upper and lower heating plates of the heating section apply pressure and heat to the insulating film from both sides. During this process, the insulating film softens and its fluidity increases, allowing it to better fill the microscopic pits and gaps on the edge surface of the photovoltaic module. Under pressure, the air inside the air bubbles is directly squeezed outwards along the gaps between the adhesive film and the edge of the photovoltaic module, thus eliminating large air bubbles and reducing their number, ensuring that the film-applied photovoltaic module meets manufacturing requirements.
[0007] In some embodiments, the heating element further includes a first mounting plate, a second mounting plate, a first lifting drive member, and a second lifting drive member, wherein: the first lifting drive member and the second lifting drive member are disposed on the mounting frame; the first mounting plate is connected to the movable end of the first lifting drive member, and the first heating plate is suspended on the lower side of the first mounting plate by a plurality of first elastic members, which contract vertically when compressed; the second mounting plate is connected to the movable end of the second lifting drive member, and the second heating plate is supported on the upper side of the second mounting plate by a plurality of second elastic members, which contract vertically when compressed.
[0008] When the first lifting drive unit lowers the first mounting plate, the first heating plate can adaptively adhere to the upper surface of the photovoltaic module edge under the floating adjustment of the first elastic element, further enhancing the compression and heating effect on the insulating film attached to the upper surface of the photovoltaic module edge. Similarly, when the second lifting drive unit lowers the second mounting plate, the second heating plate can adaptively adhere to the lower surface of the photovoltaic module edge under the floating adjustment of the second elastic element, further enhancing the compression and heating effect on the insulating film attached to the lower surface of the photovoltaic module edge.
[0009] In some embodiments, the film-applying unit includes a film supply assembly and a film-applying assembly. The film supply assembly is mounted on a mounting frame and is used to supply an insulating film of a predetermined length. The film-applying assembly includes a mounting base, a shaping stage, an adsorption strip, a translation drive, and a rotation drive. The mounting base is disposed on one side of the heating unit and slidably connected to the mounting frame. The mounting base is driven by the translation drive. The shaping stage is rotatably connected to the mounting base and driven by the rotation drive disposed on the mounting base. The shaping stage extends along the length direction of the corresponding edge of the photovoltaic module. A shaping groove is formed on the top of the shaping stage along the length direction. The adsorption strip is installed in the shaping groove along the length direction of the shaping groove and can float along the depth direction of the shaping groove. The adsorption strip floats out of the shaping groove in its natural state. The width of both the adsorption strip and the shaping groove is smaller than the width of the insulating film, and the width of the shaping groove is larger than the thickness of the photovoltaic module. The rotation drive is used for... The shaping stage is driven to rotate vertically, causing the adsorption surface of the adsorption strip to switch between a horizontal and a vertical state. When the adsorption surface of the adsorption strip rotates to a horizontal state, the film supply assembly lays an insulating film of a predetermined length along the length of the adsorption strip onto the adsorption surface. When the adsorption surface of the adsorption strip rotates to a vertical state, the adsorption strip faces the edge side of the photovoltaic module located in the heating channel. The translation drive is configured to drive the mounting base to move toward the photovoltaic module, so that after the adsorption strip attaches the insulating film to the edge side of the photovoltaic module, it is pressed into the shaping groove by the photovoltaic module. The edge of the photovoltaic module enters into the shaping groove, and the two sides of the insulating film in the width direction are deformed by the shaping groove and covered and pasted onto the upper and lower surfaces of the edge of the photovoltaic module. The translation drive is also configured to drive the mounting base to translate away from the photovoltaic module, so that the edge of the photovoltaic module moves out of the shaping groove, and the adsorption strip floats out of the shaping groove.
[0010] By setting up a film supply assembly, the predetermined length of insulating film to be attached is supplied to the film application assembly, thereby improving the automation level of this application and speeding up the work cycle.
[0011] By configuring the film-applying assembly to consist of a mounting base, a shaping platform, an adsorption strip, a translational drive, and a rotational drive, the adsorption strip receives and adsorbs the insulating film provided by the film-applying assembly when its adsorption surface is switched to a horizontal state. This ensures that the insulating film falls precisely onto the adsorption strip in a horizontal position. The rotational drive then drives the adsorption surface of the adsorption strip to face the edge of the photovoltaic module. Under the drive of the translational drive, the adsorption strip and the shaping groove cooperate to wrap and adhere the insulating film to the edge of the photovoltaic module, thus ensuring the film-applying effect and laying the foundation for subsequent pressurization and heating operations of the heating section. Compared to the film-applying method that uses pressure rollers to adhere the insulating film to the edge of the photovoltaic module during movement, the adsorption strip and shaping groove wrap and adhere the insulating film to the edge of the photovoltaic module in one go, which significantly improves the film-applying efficiency.
[0012] In some embodiments, the film-applying unit includes a film supply assembly and a film-applying assembly. The film supply assembly is mounted on a mounting frame and is used to supply an insulating film of a predetermined length. The film-applying assembly includes a mounting base, a shaping stage, an adsorption strip, and a translation drive. The mounting base is disposed on one side of the heating section and slidably connected to the mounting frame. The mounting base is drively connected to the translation drive. The shaping stage is fixedly connected to the mounting base and extends along the length direction of the corresponding edge of the photovoltaic module. A shaping groove is formed along the length direction on the side of the shaping stage facing the heating section. The adsorption strip is installed in the shaping groove along the length direction of the shaping groove and can float along the depth direction of the shaping groove. The adsorption strip floats out of the shaping groove in its natural state, and the adsorption surface of the adsorption strip faces the photovoltaic module located in the heating channel. The edge side of the module; the width of both the adsorption strip and the shaping groove is smaller than the width of the insulating film, and the width of the shaping groove is larger than the thickness of the photovoltaic module; the film supply module lays the insulating film of a predetermined length along the length direction of the adsorption strip onto the adsorption surface; the translation drive is configured to drive the mounting base to move toward the photovoltaic module, so that after the adsorption strip attaches the insulating film to the edge side of the photovoltaic module, it is pressed into the shaping groove by the photovoltaic module, and the edge of the photovoltaic module enters into the shaping groove. The two sides of the insulating film in the width direction are deformed under the action of the shaping groove and covered and pasted onto the upper and lower surfaces of the edge of the photovoltaic module; the translation drive is also configured to drive the mounting base to translate away from the photovoltaic module, so that the edge of the photovoltaic module moves out of the shaping groove and the adsorption strip floats out of the shaping groove.
[0013] By setting up a film supply assembly, the predetermined length of insulating film to be attached is supplied to the film application assembly, thereby improving the automation level of this application and speeding up the work cycle.
[0014] The film-applying assembly is configured to consist of a mounting base, a shaping table, an adsorption strip, a translation drive, and a rotation drive, with the adsorption surface of the adsorption strip facing the edge side of the photovoltaic module located in the heating channel.
[0015] After the adsorption surface of the adsorption strip receives and adsorbs the insulating film provided by the photovoltaic module, the translational drive directly drives the mounting base, shaping stage, and adsorption strip to move towards the edge of the photovoltaic module. The adsorption strip and the shaping groove cooperate to wrap and adhere the insulating film to the edge of the photovoltaic module, thus ensuring the film application effect and laying the foundation for the subsequent pressurization and heating operations of the heating section. Compared with the method of using pressure rollers to adhere the insulating film to the edge of the photovoltaic module during movement, the film application method of wrapping and adhering the insulating film to the edge of the photovoltaic module in one go through the adsorption strip and shaping groove can significantly improve the film application efficiency.
[0016] In some embodiments, the shaping table includes a base, a first shaping plate, and a second shaping plate, wherein: the base is connected to a mounting base; the first shaping plate and the second shaping plate are arranged side by side at intervals along the width direction of the base, and a shaping groove is formed between the first shaping plate and the second shaping plate.
[0017] By configuring the shaping platform as a modular assembly structure consisting of a base, a first shaping plate, and a second shaping plate, the forming of the shaping groove is facilitated. Furthermore, by adjusting the installation distance between the first and second shaping plates, the width of the shaping groove can be adjusted accordingly, thereby enabling this application to apply films to photovoltaic modules of different thicknesses and improving its versatility.
[0018] In some embodiments, the adsorption strip and the base are connected by a plurality of third elastic members spaced apart along the length of the adsorption strip, and the third elastic members contract along the depth direction of the shaping groove after being compressed.
[0019] By setting a third elastic element between the adsorption strip and the base, the adsorption strip is able to be floated.
[0020] In some embodiments, the film supply assembly includes a feeding roller, a clamping and cutting member, and a pulling member sequentially arranged on a mounting frame along the length of the forming table. The feeding roller is arranged near the first end of the forming table, wherein: the feeding roller is used to mount the insulating film roll and drive the insulating film roll to rotate to release the insulating film, and the free end of the insulating film is clamped by the clamping and cutting member; the pulling member is movably arranged on the mounting frame along the length of the forming table, and is configured to clamp the free end of the insulating film from the clamping and cutting member, and after the clamping and cutting member releases the insulating film, pull the insulating film toward the second end of the forming table until the insulating film of a predetermined length is pulled to the adsorption surface of the adsorption strip, and the clamping and cutting member is also configured to cut the insulating film.
[0021] A simple film supply assembly is provided, which can automatically prepare an insulating film of a predetermined length and pull the prepared insulating film onto the adsorption surface of an adsorption strip.
[0022] In some embodiments, the supporting mechanism includes a conveying mechanism and a lifting mechanism, wherein: the conveying mechanism includes a plurality of conveyor belts arranged side by side at intervals, each conveyor belt cooperating to carry and convey photovoltaic modules; the lifting mechanism includes a lifting drive unit, a mounting frame and a plurality of adsorption units, the mounting frame being disposed below the conveyor belts and connected to the movable end of the lifting drive unit, and the plurality of adsorption units being arranged on the mounting frame, each adsorption unit being disposed away from the conveyor belts; when the lifting drive unit drives the mounting frame to rise, each adsorption unit cooperates to lift the photovoltaic modules out of the conveying surface of the conveyor belts and cooperates to adsorb the photovoltaic modules.
[0023] Through the coordination of the conveying and lifting mechanisms, the supporting mechanism adjusts the position of the photovoltaic modules in the height direction, ensuring that the four edges of the photovoltaic modules are aligned with the heating channels of the four film-applying mechanisms. Furthermore, during the film-applying process, the supporting mechanism can magnetically hold the photovoltaic modules in place, preventing accidental slippage and ensuring a smooth application process.
[0024] In some embodiments, the adsorption unit includes a bracket, a support plate, a third lifting drive, and a suction cup, wherein: the bracket is disposed on the mounting frame, the support plate is disposed on the top of the bracket, and the support plate has a clearance hole; the third lifting drive is disposed on the mounting frame, the suction cup is connected to the movable end of the third lifting drive and is disposed corresponding to the clearance hole, and the third lifting drive is used to drive the suction cup to move up and down, so that the suction cup extends upward out of the clearance hole or retracts downward into the clearance hole.
[0025] As the conveyor belt transports the photovoltaic modules to the target position, the mounting frame rises, and the support plates of each adsorption unit first lift the photovoltaic modules upwards off the conveyor belt. Then, driven by the third lifting drive, the suction cups of each adsorption unit extend upwards through the clearance holes and adsorb the photovoltaic modules. Next, driven by the third lifting drive, the suction cups of each adsorption unit descend to pull the photovoltaic modules downwards, ultimately adsorbing and fixing the photovoltaic modules onto the support plates of each adsorption unit.
[0026] In some embodiments, the photovoltaic module edge sealing device further includes a straightening mechanism; the straightening mechanism includes four straightening members arranged around the four sides of the lifting mechanism; the straightening members are respectively configured to move toward or away from the side of the photovoltaic module on the lifting mechanism to straighten the position of the photovoltaic module; the lifting mechanism is configured to adsorb and fix the photovoltaic module after the straightening mechanism has completed the straightening.
[0027] By setting up a alignment mechanism, which includes four alignment components surrounding the four sides of the lifting mechanism, the position of the photovoltaic module can be aligned before film application, ensuring that the four edges of the photovoltaic module are parallel to the heating channels of the corresponding film application mechanism, thus improving the film application accuracy.

Detailed Implementation
[0030] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0031] In this specification, for ease of description and consistent understanding, the relative positional relationships of the components will be defined with reference to the directions shown in the accompanying drawings. For example, the use of directional terms such as "upper," "lower," "top," and "bottom" is generally based on the layout of the drawings. It should be understood that these directional terms are only for the convenience of describing this application 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 application.
[0032] As described in the background section, existing photovoltaic module edge sealing equipment typically uses a pressure roller to move along the edge of the module for edge sealing. After edge sealing using the pressure roller method, a large number of large-diameter air bubbles are easily formed between the insulating film and the upper and lower surfaces of the photovoltaic module, which cannot meet the module quality requirements.
[0033] In view of this, this application provides a photovoltaic module edge sealing device for attaching an insulating film to the four edges of a photovoltaic module.
[0034] like Figures 1 to 4 As shown, the photovoltaic module edge-sealing equipment of this application includes: The support mechanism 20 is used to support the photovoltaic module 100 to be coated with film.
[0035] Four film-applying mechanisms 10 are arranged around the top four sides of the support mechanism 20, and are used to apply insulating film to the four edges of the photovoltaic module 100 on the support mechanism 20.
[0036] The film application mechanism 10 includes a translation drive mechanism (not shown in the figure), a mounting frame 1, a film application part 2, and a heating part 3. The mounting frame 1 is connected to the movable end of the translation drive mechanism. The film application part 2 and the heating part 3 are both mounted on the mounting frame 1. The heating part 3 includes a first heating plate 31 and a second heating plate 32 arranged vertically opposite each other. The first heating plate 31 and the second heating plate 32 can move closer to each other or further away from each other. A heating channel that can accommodate one edge of the photovoltaic module 100 is formed between the first heating plate 31 and the second heating plate 32.
[0037] The translation drive mechanism drives the mounting bracket 1 to move toward the corresponding edge of the photovoltaic module 100, so that the edge of the photovoltaic module 100 enters the corresponding heating channel. The film-applying part 2 is used to apply an insulating film to the corresponding edge of the photovoltaic module 100, so that the insulating film adheres to the upper, side and lower surfaces of the edge of the photovoltaic module 100. The first heating plate 31 and the second heating plate 32 are configured to press the corresponding edge of the photovoltaic module 100 from the upper and lower sides to compress and heat the insulating film applied to the upper and lower surfaces of the edge of the photovoltaic module 100.
[0038] The optional working process of the photovoltaic module edge-sealing equipment in this embodiment is as follows: The supporting mechanism 20 first adjusts the photovoltaic module 100 to the target position and fixes the photovoltaic module 100 so that the four edges of the photovoltaic module 100 are aligned with the heating channels of the four film-applying mechanisms 10.
[0039] Subsequently, the four translation drive mechanisms drive the four film-applying mechanisms 10 to move toward the four sides of the photovoltaic module 100, so that the four sides of the photovoltaic module 100 enter the heating channels of the corresponding film-applying mechanism 10, so as to complete the synchronous film application to the four sides of the photovoltaic module 100.
[0040] The film application process of each film application mechanism 10 is as follows: The film application section 2 applies an insulating film to one edge of the photovoltaic module 100, so that the insulating film adheres to the upper, side, and lower surfaces of one edge of the photovoltaic module 100. Subsequently, the first heating plate 31 and the second heating plate 32 of the heating section 3 move closer together to pressurize and heat the insulating film from both the top and bottom. During this process, the insulating film softens and its fluidity increases, thereby better filling the micro-pits and film application gaps on the edge surface of the photovoltaic module. Under pressure, the air inside the bubbles is directly squeezed outward along the edge gaps of the adhesive film and the photovoltaic module, thereby eliminating large-sized bubbles and reducing the number of bubbles, so that the photovoltaic module after film application meets manufacturing requirements. After the pressing and heating operation on the edge of the photovoltaic module 100 is completed, the first heating plate 31 and the second heating plate 32 of each film application mechanism 10 are controlled to return to a state of mutual distance.
[0041] Finally, the four translation drive mechanisms drive the four film-applying mechanisms 10 to move away from the four sides of the photovoltaic module 100, so that the four sides of the photovoltaic module 100 are withdrawn from the corresponding heating channels.
[0042] The translation drive mechanism can be a linear drive mechanism with various existing structures that can drive the corresponding film-applying mechanism 10 to translate toward or away from the photovoltaic module 100. For example, a screw drive mechanism composed of components such as a motor, lead screw, and nut, or a cylinder drive mechanism composed of components such as a cylinder and slide rail pair.
[0043] In other embodiments, to avoid interference between two adjacent film-applying mechanisms 10 during the film-applying process, the four film-applying mechanisms 10 can also complete the film-applying operation on the four sides of the photovoltaic module 100 in stages. For example, two of the film-applying mechanisms 10 arranged opposite each other first complete the film-applying operation on two sides (such as the two long sides) of the photovoltaic module 100, and the other two film-applying mechanisms 10 arranged opposite each other complete the film-applying operation on the other two sides (such as the two short sides) of the photovoltaic module 100.
[0044] like Figures 4 to 6As shown, in some embodiments, the heating unit 3 further includes a first mounting plate 33, a second mounting plate 34, a first lifting drive member 35, and a second lifting drive member 36, wherein: the first lifting drive member 35 and the second lifting drive member 36 are disposed on the mounting frame 1. The first mounting plate 33 is connected to the movable end of the first lifting drive member 35, and the first heating plate 31 is suspended below the first mounting plate 33 by a plurality of first elastic members, which contract vertically when compressed. The second mounting plate 34 is connected to the movable end of the second lifting drive member, and the second heating plate 32 is supported above the second mounting plate 34 by a plurality of second elastic members, which contract vertically when compressed.
[0045] When the first lifting drive 35 drives the first mounting plate 33 to descend, under the floating adjustment of the first elastic element, the first heating plate 31 can adaptively adhere to the upper surface of the edge of the photovoltaic module 100, further enhancing the squeezing and heating effect on the insulating film attached to the upper surface of the edge of the photovoltaic module 100. Similarly, when the second lifting drive 36 drives the second mounting plate 34 to descend, under the floating adjustment of the second elastic element, the second heating plate 32 can adaptively adhere to the lower surface of the edge of the photovoltaic module 100, further enhancing the squeezing and heating effect on the insulating film attached to the lower surface of the edge of the photovoltaic module 100.
[0046] Both the first and second elastic elements can be springs with guide rods. Taking the first elastic element as an example, the guide rod is set vertically, with one end fixedly connected to the first heating plate 31, and the other end slidably connected to the first mounting plate 3. The spring is fitted onto the guide rod, with both ends abutting against the first mounting plate 33 and the first heating plate 31, respectively. The first lifting drive component 35 and the second lifting drive component 36 can be driven by cylinders, electric cylinders, or other similar components.
[0047] like Figures 4 to 9 As shown, in some embodiments, the film application part 2 includes a film supply assembly 4 and a film application assembly 5, wherein the film supply assembly 4 is mounted on the mounting frame 1 and is used to supply an insulating film of a predetermined length.
[0048] The film-applying assembly 5 includes a mounting base 51, a shaping platform 52, an adsorption strip 53, a translation drive 54, and a rotation drive 55. The mounting base 51 is disposed on one side of the heating section 3 and slidably connected to the mounting frame 1. The mounting base 51 is driveably connected to the translation drive 54. The shaping platform 52 is rotatably connected to the mounting base 51 and drively connected to the rotation drive 55 disposed on the mounting base 51. The shaping platform 52 extends along the length direction of the corresponding edge of the photovoltaic module 100. A shaping groove 56 is formed on the top of the shaping platform 52 along its length direction. The adsorption strip 53 is installed within the shaping groove 56 along its length direction and can float along its depth direction. The adsorption strip 53 floats out of the shaping groove 56 in its natural state. The width of both the adsorption strip 53 and the shaping groove 56 is smaller than the width of the insulating film, and the width of the shaping groove 56 is greater than the thickness of the photovoltaic module 100.
[0049] The rotary drive 55 drives the shaping table 52 to rotate vertically, switching the adsorption surface of the adsorption strip 53 between a horizontal and a vertical state. When the adsorption surface of the adsorption strip 53 is rotated to the horizontal state, the film supply assembly 4 lays an insulating film of a predetermined length along the length of the adsorption strip 53 onto the adsorption surface. When the adsorption surface of the adsorption strip 53 is rotated to the vertical state, the adsorption strip 53 faces the edge side of the photovoltaic module 100 located in the heating channel. The translation drive 54 is configured to drive the mounting base 51 to move toward the photovoltaic module 100, so that after the adsorption strip 53 attaches the insulating film to the edge side of the photovoltaic module 100, it is pressed into the shaping groove 56 by the photovoltaic module 100. The edge of the photovoltaic module 100 enters the shaping groove 56, and the two edges of the insulating film in the width direction are deformed and covered and pasted onto the upper and lower surfaces of the edge of the photovoltaic module 100 under the action of the shaping groove 56. The translation drive 54 is also configured to drive the mounting base 51 to translate away from the photovoltaic module 100, so that the edge of the photovoltaic module 100 moves out of the shaping groove 56 and the adsorption strip 53 floats out of the shaping groove.
[0050] The optional film application process for the film application part 2 in this embodiment is as follows: like Figure 8 and Figure 9 As shown, the rotary drive 55 drives the shaping table 52 to rotate vertically, causing the adsorption surface of the adsorption strip 53 to switch to a horizontal state. The film supply assembly 4 supplies an insulating film of a predetermined length onto the horizontally positioned adsorption strip 53, and the adsorption strip 53 adsorbs the insulating film.
[0051] Subsequently, as Figure 10 As shown, the rotating drive 55 drives the shaping table 52 to rotate vertically, so that the adsorption surface of the adsorption strip 53 rotates to an upright state, and the adsorption strip 53 and the insulating film on it face the edge side of the photovoltaic module 100 located in the heating channel.
[0052] Next, the translation drive 54 drives the mounting base 51 to move towards the photovoltaic module 100, causing the adsorption strip 53 to adhere the insulating film to the edge side of the photovoltaic module 100. During this process, the edge of the photovoltaic module 100 is pressed into the shaping groove 56, and the two edges of the insulating film in the width direction are deformed and covered and adhered to the upper and lower surfaces of the edge of the photovoltaic module 100 under the action of the shaping groove 56. The adsorption strip 53 is completely retracted into the shaping groove 56 under the pressure of the photovoltaic module 100. The adsorption strip 53 elastically presses against the side edge of the photovoltaic module 100, which on the one hand avoids the edge of the photovoltaic module 100, and on the other hand compresses the insulating film attached to the side edge of the photovoltaic module 100, improving the adhesion effect of the insulating film in this area.
[0053] After the film is applied, the translation drive 54 drives the mounting base 51 to move away from the photovoltaic module 100, so that the edge of the photovoltaic module 100 moves out of the shaping groove 56, and the adsorption strip 53 floats out of the shaping groove 56 again.
[0054] As can be seen, by setting up the film supply assembly 4, the predetermined length of insulating film to be applied is supplied to the film application assembly 5, thereby improving the automation level of the film application unit 2 and speeding up the work cycle.
[0055] The film-applying assembly 5 is configured to consist of a mounting base 51, a shaping table 52, an adsorption strip 53, a translation drive 54, and a rotation drive 55. When the adsorption surface of the adsorption strip 53 is switched to a horizontal state, it receives and adsorbs the insulating film supplied by the film assembly 4, ensuring that the insulating film falls precisely onto the adsorption strip 53 in a horizontal state and is adsorbed by the adsorption strip 53, preventing the adsorption strip 53 from sagging. During the film-applying process, the cooperation between the adsorption strip 53 and the shaping groove 56 ensures that the insulating film can be firmly wrapped and pasted to the sides and top and bottom surfaces of the photovoltaic module 100, improving the film-applying effect and laying the foundation for the subsequent pressurization and heating operations of the heating section 3.
[0056] Furthermore, compared to using a pressure roller to apply the insulating film segment by segment to the edge of the photovoltaic module 100 during movement, using the adsorption strip 53 and shaping groove 56 to wrap and apply the insulating film to the edge of the photovoltaic module 100 in one go can significantly improve the film application efficiency. Of course, in other embodiments, the film application part 2 can also adopt a traditional pressure roller film application structure.
[0057] like Figure 9 As shown, the adsorption surface of the adsorption strip 53 is provided with a plurality of adsorption holes 531 arranged at intervals along the length direction of the adsorption strip 53, and the adsorption surface adsorbs the insulating film through the adsorption holes 531 thereon.
[0058] like Figures 7 to 9As shown, in some embodiments, multiple mounting bases 51 are provided, and the multiple mounting bases 51 are spaced apart along the length direction (e.g., the X direction) of the shaping table 53. Each mounting base 51 includes a sliding plate 511 and a connecting block 512. The mounting frame 1 is provided with a slide rail perpendicular to the length direction of the shaping table 53 at the position corresponding to the sliding plate 511. The sliding plate 511 is slidably connected to the slide rail. The connecting block 512 is provided on the sliding plate 511, and a shaft hole is provided in the connecting block 512.
[0059] The rotary drive 55 includes a rotary motor 551 and a rotating shaft 552 extending along the length of the shaping table 52. The rotating shaft 552 passes through the shaft hole of the connecting block 513 of each mounting base 51 and can rotate around its own axis. The parts of the shaping table 53 corresponding to each mounting base 51 are fixedly connected to the rotating shaft 552.
[0060] Two or more translation drive units 54 can be set, for example Figure 7 Each of the two translation drive components 54 corresponds to one of the mounting seats 51. Since each mounting seat 51 is linked by a rotating shaft 552, when the translation drive component 54 drives the corresponding mounting seat 51 to slide and translate along the slide rail, it can drive all the mounting seats 51 to translate synchronously, ultimately realizing the translation drive of the shaping table 52 and the adsorption strip 53, and improving the translation stability of the shaping table 52 and the adsorption strip 53 to avoid deviation.
[0061] When the rotary motor 551 drives the rotating shaft 552 to rotate around its own axis, the rotating shaft 552 drives the shaping table 53 to rotate vertically, thereby causing the adsorption surface of the adsorption strip 53 to switch between a horizontal state and a vertical state.
[0062] In other embodiments, the film application section 2 includes a film supply assembly 4 and a film application assembly 5, wherein the film supply assembly 4 is mounted on the mounting frame 1 and is used to supply an insulating film of a predetermined length.
[0063] In these embodiments, the structure of the film application assembly 5 is similar to... Figures 4 to 9The structures of the film-applying components 5 in the embodiments are basically the same. Therefore, for the sake of description, the same reference numerals in the figures will still be used for the same components below. Unlike the above embodiments, the film-applying component 5 does not have a rotation drive mechanism, and the adsorption surface of its adsorption strip 53 remains in a vertical state. Specifically, the film-applying component 5 includes a mounting base 51, a shaping table 52, an adsorption strip 53, and a translation drive 54. The mounting base 51 is disposed on one side of the heating part 3 and slidably connected to the mounting frame 1. The mounting base 51 is drively connected to the translation drive 54. A shaping table 52 is fixedly connected to the mounting base 51 and extends along the length of the corresponding edge of the photovoltaic module 100. A shaping groove 56 is formed along the length of the side of the shaping table 52 facing the heating part 3. An adsorption strip 53 is installed in the shaping groove 56 along its length and can float along its depth. The adsorption strip 53 floats out of the shaping groove 56 in its natural state, and the adsorption surface of the adsorption strip 53 faces the edge side of the photovoltaic module 100 located in the heating channel. The width of both the adsorption strip 53 and the shaping groove 56 is smaller than the width of the insulating film, and the width of the shaping groove 56 is greater than the thickness of the photovoltaic module 100. The film supply assembly 4 lays an insulating film of a predetermined length onto the adsorption surface along the length of the adsorption strip.
[0064] The translation drive 54 is configured to drive the mounting base 51 to move toward the photovoltaic module 100, so that after the adsorption strip 53 applies the insulating film to the edge side of the photovoltaic module 100, it is pressed into the shaping groove 56 by the photovoltaic module 100. The edge of the photovoltaic module 100 enters the shaping groove 56, and the two sides of the insulating film in the width direction are deformed by the shaping groove 56 and covered and adhered to the upper and lower surfaces of the edge of the photovoltaic module 100. The translation drive 54 is also configured to drive the mounting base 51 to translate away from the photovoltaic module 100, so that the edge of the photovoltaic module 100 moves out of the shaping groove 56, and the adsorption strip 53 floats out of the shaping groove.
[0065] The film application process of the film application part 2 in this embodiment is as follows: The film supply assembly 4 supplies an insulating film of a predetermined length to the vertical adsorption surface of the adsorption strip 53, and the adsorption strip 53 adsorbs the insulating film.
[0066] Next, the translation drive 54 drives the mounting base 51 to move towards the photovoltaic module 100, causing the adsorption strip 53 to adhere the insulating film to the edge side of the photovoltaic module 100. During this process, the edge of the photovoltaic module 100 is pressed into the shaping groove 56, and the two edges of the insulating film in the width direction are deformed and covered and adhered to the upper and lower surfaces of the edge of the photovoltaic module 100 under the action of the shaping groove 56. Under the pushing of the adsorption strip 53, it is completely retracted into the shaping groove 56 and elastically pressed against the side of the edge of the photovoltaic module 100. This allows for both avoidance of the edge of the photovoltaic module 100 and compression of the insulating film attached to the side of the edge of the photovoltaic module 100, improving the adhesion effect of the insulating film in this area.
[0067] After the film is applied, the translation drive 54 drives the mounting base 51 to move away from the photovoltaic module 100, so that the edge of the photovoltaic module 100 moves out of the shaping groove 56, and the adsorption strip 53 floats out of the shaping groove 56 again.
[0068] As can be seen, by setting up the film supply assembly 4, the predetermined length of insulating film to be applied is supplied to the film application assembly 5, thereby improving the automation level of the film application unit 2 and speeding up the work cycle.
[0069] The film-applying assembly is configured to consist of a mounting base 51, a shaping table 52, an adsorption strip 53, a translation drive 54, and a rotation drive 55, with the adsorption surface of the adsorption strip 53 facing the edge side of the photovoltaic module 100 located in the heating channel.
[0070] Since the adsorption surface of the adsorption strip 53 remains vertical, after the adsorption surface of the adsorption strip 53 adsorbs the insulating film provided by the film supply module 4, the translation drive 54 then drives the mounting base 51, the shaping table 52 and the adsorption strip 53 to translate towards the edge of the photovoltaic module 100. The adsorption strip 53 and the shaping groove 56 cooperate with each other to cover and stick the insulating film to the edge of the photovoltaic module 100, thereby improving the film application efficiency.
[0071] like Figures 8 to 9 As shown, in some embodiments, the shaping table 52 includes a base 521, a first shaping plate 522, and a second shaping plate 523, wherein: the base 521 is connected to the mounting base 51. The first shaping plate 522 and the second shaping plate 523 are arranged side by side at intervals along the width direction (e.g., the Y direction) of the base 521, and a shaping groove 56 is formed between the first shaping plate 522 and the second shaping plate 523.
[0072] By configuring the shaping platform 52 as a split assembly structure consisting of a base 521, a first shaping plate 522, and a second shaping plate 523, the construction and shaping of the shaping groove 56 is facilitated. Furthermore, by adjusting the installation distance between the first shaping plate 522 and the second shaping plate 523, the width of the shaping groove 56 can be adjusted accordingly, thereby enabling the film-applying assembly 5 to apply films to photovoltaic modules 100 of different thicknesses, improving the versatility of this application.
[0073] In some embodiments, a first inclined surface 524 is formed on the upper end of the side of the first shaping plate 522 opposite to the second shaping plate 523, and a second inclined surface 525 is formed on the upper end of the side of the second shaping plate 523 opposite to the first shaping plate 522. The first inclined surface 524 and the second inclined surface 525 constitute the entrance of the shaping groove 56, and the entrance of the shaping groove 56 is outwardly expanded.
[0074] The outwardly expanding entrance of the shaping groove 56, which is composed of the first inclined surface 524 and the second inclined surface 525, enables the avoidance and guidance of the edge of the photovoltaic module 100, so that the edge of the photovoltaic module 100 can enter the shaping groove 56 more smoothly, preventing collisions that could damage the edge of the photovoltaic module 100.
[0075] In some embodiments, the adsorption strip 53 and the base 521 are connected by a plurality of third elastic members spaced apart along the length of the adsorption strip 53. These third elastic members contract along the depth direction of the shaping groove 56 when compressed. By providing the third elastic members between the adsorption strip 53 and the base 521, the adsorption strip 53 can adaptively float according to the pressure applied. The third elastic members can, for example, be springs that can extend and retract along the depth direction of the shaping groove 56.
[0076] like Figures 4 to 6 As shown, in some embodiments, the film supply assembly 4 includes a feeding roller 41, a pressing and cutting member 42, and a pulling member 43 sequentially arranged on the mounting frame 1 along the length direction (e.g., the X direction) of the forming table 52. The feeding roller 41 is located near the first end of the forming table 42, wherein: the feeding roller 41 is used to install the insulating film roll and drive the insulating film roll to rotate to release the insulating film, and the free end of the insulating film is pressed by the pressing and cutting member 42. The pulling member 43 is movably arranged on the mounting frame 1 along the length direction of the forming table 52, and is configured to clamp the free end of the insulating film from the pressing and cutting member 42, and after the pressing and cutting member releases the insulating film, pull the insulating film toward the second end of the forming table 52 until the insulating film of a predetermined length is pulled to the adsorption surface of the adsorption strip 53. The pressing and cutting member 42 is also configured to cut the insulating film.
[0077] As can be seen, through the cooperation of the feeding roller 41, the pressing and cutting part 42, and the pulling part 43, the film supply assembly 4 realizes the automatic preparation of the insulating film with a predetermined length and pulls the prepared insulating film onto the adsorption surface of the adsorption strip 53.
[0078] In some embodiments, the clamping and cutting member 42 is movably disposed on the mounting bracket 1 along a first direction. This arrangement allows for flexible adjustment of the distance between the clamping and cutting member 42 and the suction strip 53.
[0079] like Figure 2 As shown, in some embodiments, the carrying mechanism 20 includes a conveying mechanism 201 and a lifting mechanism 202, wherein: the conveying mechanism 201 includes a plurality of (e.g., Figure 2 The four conveyor belts are arranged side by side at intervals, and each conveyor belt works together to carry and transport 100 photovoltaic modules.
[0080] The lifting mechanism 202 includes a lifting drive unit 203, a mounting frame 204, and several adsorption units 205. The mounting frame 204 is located below the conveyor belt and connected to the movable end of the lifting drive unit 203. The adsorption units 205 are arranged on the mounting frame 204, and each adsorption unit 205 is positioned away from the conveyor belt. When the lifting drive unit 203 drives the mounting frame 204 to rise, each adsorption unit 205 cooperates to lift the photovoltaic module 100 out of the conveyor surface of the conveyor belt and to adsorb the photovoltaic module 100.
[0081] The optional working process of the bearing mechanism 20 is as follows: In the initial state, the mounting frame 204 is in a low position, and the adsorption surface of the adsorption unit 205 is located below the conveying surface of the conveyor belt.
[0082] After the conveyor belt transports the photovoltaic module 100 to the target position, the lifting drive unit 203 is driven to rise to a high position. This causes several adsorption units 205 to lift the photovoltaic module 100 off the conveyor belt and adsorb and fix the photovoltaic module 100, preventing the photovoltaic module 100 from accidentally sliding during the film application process.
[0083] After the four film-applying mechanisms 10 have finished applying the film to the four edges of the photovoltaic module 100, the lifting drive unit 203 drives the mounting frame 204 to descend to the low position, and each adsorption unit 205 stops adsorption, so that the photovoltaic module 100 with the film applied falls back onto the conveyor belt.
[0084] As can be seen, through the cooperation of the conveying mechanism 201 and the lifting mechanism 202, the supporting mechanism 20 achieves the position adjustment of the photovoltaic module 100, so that the four edges of the photovoltaic module 100 are aligned with the heating channels of the four film-applying mechanisms 10. In addition, during the film-applying process, the supporting mechanism 20 can adsorb and fix the photovoltaic module 100, thereby preventing the photovoltaic module 100 from accidentally sliding during the film-applying process and ensuring the smooth implementation of the film-applying process.
[0085] like Figure 2 As shown, in some embodiments, the adsorption unit 205 includes a bracket 206, a support plate 207, a third lifting drive 208, and a suction cup 209. The bracket 206 is mounted on the mounting frame 204, and the support plate 207 is mounted on top of the bracket 206, having clearance holes. The third lifting drive 208 is mounted on the mounting frame 204, and the suction cup 209 is connected to the movable end of the third lifting drive 208 and corresponds to the clearance holes. The third lifting drive 208 drives the suction cup 209 to move up and down, causing the suction cup 209 to extend upwards into the clearance holes or retract downwards into them.
[0086] When the conveyor belt transports the photovoltaic module 100 to the target position, the lifting drive unit 203 drives the mounting frame 204 to rise to a high position, causing the support plates 207 of each adsorption unit 205 to first lift the photovoltaic module 100 upwards out of the conveyor belt. Subsequently, the suction cups 209 of each adsorption unit 205 extend upwards through the clearance holes under the drive of the third lifting drive unit 208 and adsorb the photovoltaic module. Next, the suction cups 209 of each adsorption unit 205 descend under the drive of the third lifting drive unit 208 to pull the photovoltaic module 100 downwards, ultimately causing the photovoltaic module 100 to be adsorbed and fixed on the support plates 207 of each adsorption unit 205.
[0087] In some embodiments, the four film-applying mechanisms 10 are arranged at the same height. When the lifting drive unit 203 drives the mounting frame 204 to rise to a predetermined height, the four sides of the photovoltaic module 100 are aligned with the heating channels of the four film-applying mechanisms 10. In this way, the four film-applying mechanisms 10 can perform the film-applying operation on the four sides of the photovoltaic module 100 simultaneously or in stages.
[0088] In other embodiments, to avoid interference between adjacent film-applying mechanisms 10 during the film-applying process, the four film-applying mechanisms 10 can be arranged at different heights. For example, two of the film-applying mechanisms 10 are located at a first height, and the other two are located at a second height. The four film-applying mechanisms 10 complete the film-applying operation on the four sides of the photovoltaic module 100 in two stages. Specifically, the lifting drive unit 203 first drives the mounting frame 204 to rise to a first position, so that two side edges (such as the two long side edges) of the photovoltaic module 100 are aligned with the heating channels of the two film-applying mechanisms 10 at the first height. After the two film-applying mechanisms 10 at the first height have completed applying film to one of the two side edges of the photovoltaic module 100, the lifting drive unit 203 drives the photovoltaic module 100 to the second position, so that the other two side edges (such as the two short side edges) of the photovoltaic module 100 are aligned with the heating channels of the two film-applying mechanisms 10 at the second height, and the two film-applying mechanisms 10 at the second height then apply film to the other two side edges of the photovoltaic module 100.
[0089] In other embodiments, the lifting mechanism 202 does not perform lifting actions, while the conveyor belt of the conveying mechanism 201 is configured to be liftable. The conveyor belt first transports the photovoltaic module at a high position. When the conveyor belt transports the photovoltaic module 100 to the target position, the conveyor belt descends relative to the lifting mechanism 202, thereby placing the photovoltaic module onto the bearing surface of the lifting mechanism 202. The lifting mechanism then performs adsorption and fixation on the photovoltaic module 100. Next, the film can be applied to the four sides of the photovoltaic module at the height of the lifting mechanism.
[0090] like Figure 2 As shown, in some embodiments, the photovoltaic module edge sealing device of this application further includes a straightening mechanism 30. The straightening mechanism 30 includes four straightening members 301 arranged around the four sides of the lifting mechanism. The straightening members 301 are respectively configured to move toward or away from the side of the photovoltaic module on the lifting mechanism 202 to straighten the position of the photovoltaic module. The lifting mechanism 202 is configured to adsorb and fix the photovoltaic module after the straightening mechanism 30 has completed the straightening. In this way, the position of the photovoltaic module 100 can be corrected before film application, ensuring that the four sides of the photovoltaic module 10 are parallel to the heating channels of the corresponding film application mechanism 10, thereby improving the film application accuracy.
[0091] In some embodiments, the preform 301 positioned in front of the target position is configured to be height-adjustable. Before the conveying mechanism 202 conveys the photovoltaic module 100 to the target position, the preform 301 positioned in front of the target position rises to a working position to extend upwards beyond the conveying surface of the conveyor belt. Thus, when the conveying mechanism 202 conveys the photovoltaic module 100 to the target position, the first preform 301 can act as a blocking limit on the photovoltaic module 100, preventing the photovoltaic module 100 from being over-conveyed and deviating from the target position.
[0092] After the photovoltaic module 100 is transported to the target position, the conveyor belt stops transporting, and then the four straightening components 301 move synchronously toward the side of the photovoltaic module to straighten the four sides of the photovoltaic module 100, or to straighten the four sides of the photovoltaic module 100 in a predetermined sequence.

The scope of protection claimed in this application is defined by the claims, not by the above descriptions in the embodiments.
