Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module production technology, and in particular relates to a film laying mechanism and film laying equipment. Background Technology

[0002] To improve the quality and reduce the cost of photovoltaic (PV) modules, a new type of PV module has been designed. This new module uses a steel frame instead of an all-aluminum frame; the steel frame is fitted around the glass to form the module, reducing both the size and cost. Before fitting the steel frame to the glass, an adhesive film needs to be applied around the glass for bonding and cushioning. However, the film's high elasticity, narrow width, and thinness make it prone to bending and wrinkling, and difficult to secure. To ensure a better fit between the film and the steel frame, the film needs to be applied to both the top and sides of the glass. Therefore, when laying the film at the edge of the glass, a certain width of the film needs to protrude from the PV module. Then, it is bent downwards to adhere the protruding film to the side of the PV module, thus simultaneously adhering to both the top and sides. For this process, automated equipment needs to be designed to lay the film.

[0003] In the prior art, the foam tape synchronous four-sided application device disclosed in Chinese Patent Publication No. CN109120223B uses foam tape as a frame bonding material. The device can apply foam tape to all four sides of the photovoltaic module. The left, right, front, and rear edge sealing components reset, while the edge sealing wheels move forward. Because the spacing between the four sets of edge sealing wheels is gradually decreasing, a simulated gradual pressing action is created to press the foam tape onto the upper and lower surfaces of the photovoltaic module. However, in this solution, the foam tape is adhered to the upper and lower surfaces of the photovoltaic module, and this is done by rolling the edge sealing wheels. Due to the high elasticity, narrow width, and thinness of the adhesive film, rolling with edge sealing wheels is not feasible. Furthermore, this solution cannot adhere the adhesive film to the upper surface and sides of the photovoltaic module.

[0004] Therefore, it is necessary to provide a film laying mechanism and film laying equipment to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this invention is to provide a film laying mechanism that can ensure that the film is firmly adhered to the upper surface and sides of the photovoltaic module, facilitating subsequent frame assembly operations.

[0006] This utility model achieves the above objective through the following technical solution: a film laying mechanism, comprising:

[0007] The laying unit is used to adsorb the adhesive film and lay it onto the edge of the photovoltaic module;

[0008] A bending and shaping unit is used to bend the adhesive film and firmly attach it to the upper surface and side of the photovoltaic module. The bending and shaping unit includes a first driving member and a first mounting frame that is driven by the first driving member to move up and down. A heating member for heating the adhesive film is installed at the bottom of the first mounting frame along the length direction. An air blowing member for blowing air onto the adhesive film to achieve the bending action of the adhesive film is installed next to the heating member.

[0009] The first support plate, wherein the laying unit and the bending and shaping unit are jointly disposed on the first support plate.

[0010] Furthermore, the laying unit includes a lifting drive module mounted on the first support plate and a lifting frame driven by the lifting drive module to perform lifting actions. The bottom of the lifting frame is provided with a plurality of adsorption components for adsorbing adhesive film along the length direction.

[0011] Another objective of this invention is to provide a film laying device in which multiple film laying mechanisms work simultaneously, thereby improving the efficiency of film laying.

[0012] This utility model achieves the above objective through the following technical solution: a film laying device, comprising:

[0013] A conveying device used to transport photovoltaic modules;

[0014] A straightening mechanism that straightens the photovoltaic modules on the conveying device on all four sides;

[0015] A film feeding device, used to supply film;

[0016] The aforementioned film laying mechanism transports the film from the film feeding device onto the photovoltaic module and lays the film onto the photovoltaic module.

[0017] Furthermore, the film feeding device includes a film feeding mechanism and a support platform disposed next to the film feeding mechanism for placing the cut film.

[0018] Furthermore, the film feeding mechanism includes a mounting bracket, a film release module, a feeding module for continuing to convey the released film forward, and a clamping assembly for clamping the film. A detection module is provided between the feeding module and the clamping assembly. The feeding module and the clamping assembly are electrically connected to the detection module. The detection module receives electrical signals from the clamping assembly to detect the tightness of the film. The feeding module adjusts the film unwinding speed according to the electrical signals from the detection module.

[0019] Furthermore, it also includes a buffer module and a film pressing assembly disposed between the feeding module and the feeding module, a peeling assembly disposed between the feeding module and the detection module, and a cutting assembly disposed on one side of the clamping assembly, with a collection module for collecting release paper disposed below the peeling assembly.

[0020] Furthermore, the carrying platform is provided with a number of adsorption holes for adsorbing the adhesive film, and each adsorption hole is provided with a limiting pin on both sides to limit the position of the adhesive film, and the adhesive film is restricted between the two rows of limiting pins.

[0021] Furthermore, four film feeding mechanisms are provided and located at the four corners of the conveying device, and four corresponding bearing platforms are provided and located on the four sides of the photovoltaic module.

[0022] Furthermore, there are four film laying mechanisms, located on the four sides of the photovoltaic module. The four film laying mechanisms are a front film laying mechanism, a rear film laying mechanism, a left film laying mechanism, and a right film laying mechanism, which respectively lay the film on the front, rear, left, and right sides of the photovoltaic module.

[0023] Furthermore, the front film laying mechanism and the rear film laying mechanism are jointly driven by a first linear drive module to move back and forth, and the front film laying mechanism and the rear film laying mechanism simultaneously move closer to or further away from the photovoltaic module; the left film laying mechanism and the right film laying mechanism are jointly driven by a second linear drive module to move left and right, and the left film laying mechanism and the right film laying mechanism simultaneously move closer to or further away from the photovoltaic module.

[0024] Compared with the prior art, the beneficial effects of the adhesive film laying mechanism and adhesive film laying equipment of this utility model are as follows:

[0025] (1) There are four film laying mechanisms, which are located on the four sides of the photovoltaic module. They can simultaneously lay the film on the four sides of the photovoltaic module. The four film laying mechanisms work at the same time, which improves the efficiency of film laying.

[0026] (2) The film laying mechanism includes a laying unit and a bending and shaping unit. The laying unit can adsorb the film and lay the film to the edge of the photovoltaic module. The blowing part of the bending and shaping unit is aligned with the outer film to bend it and cover the side of the photovoltaic module. The heating part is aligned with the film to firmly stick the film to the upper surface and side of the photovoltaic module. This ensures that the film is firmly stuck to the upper surface and side of the photovoltaic module, which is convenient for subsequent frame assembly operations.

[0027] (3) The detection module on the film feeding mechanism can detect the tightness of the film. When the clamping component clamps the film, the detection module will detect the tightness of the film. If the film is detected to be in a relaxed state, it is determined that the film has not been overstretched. If the film is detected to be in a tense state, it is determined that the film has been overstretched. Then the feeding module will continue to feed a section of film forward so that the film at the clamping component is in a relaxed state. This can prevent the film from being overstretched and deformed. Therefore, this solution is applicable to the feeding of elastic film and can also avoid the problem of the film being stretched and deformed. Attached Figure Description

[0050] Please refer to Figures 1-14 This embodiment is a film laying device 100, which includes:

[0051] Conveying device 1, which is used to transport photovoltaic modules;

[0052] Correction mechanism 2 is used to correct the four sides of the photovoltaic modules on the conveying device 1;

[0053] Adhesive film feeding device 3, which is used to supply adhesive film;

[0054] The adhesive film laying mechanism 4 is used to transport the adhesive film on the adhesive film feeding device 3 onto the photovoltaic module and lay the adhesive film onto the photovoltaic module.

[0055] The conveying device 1 includes several parallel conveyor belts 11 and a conveying motor 12 that drives the conveyor belts 11 to perform conveying operations. The conveying device 1 is prior art and will not be described in detail here. In order to ensure the stability of the conveying by the conveying device 1, support wheel sets 13 are provided between the conveyor belts 11 or on the sides of the conveyor belts 11, which can increase the support area of ​​the photovoltaic modules and ensure the stability of the conveying.

[0056] The alignment mechanism 2 includes a front alignment component 21 for aligning the front end of the photovoltaic module, a rear alignment component 22 for aligning the rear end of the photovoltaic module, a left alignment component 23 for aligning the left side of the photovoltaic module, and a right alignment component 24 for aligning the right side of the photovoltaic module. Two front alignment components 21 and two rear alignment components 22 are provided. The front and rear alignment components 21 and 22 are jointly driven by a third linear drive module 25 to move back and forth, simultaneously moving closer to or further away from the photovoltaic module. The left and right alignment components 23 and 24 are jointly driven by a fourth linear drive module 26 to move left and right, simultaneously moving closer to or further away from the photovoltaic module. The placement of the third and fourth linear drive modules 25 and 26 allows for adaptation to photovoltaic modules of different widths and lengths, improving the versatility of the installation equipment. The front alignment component 21 and the rear alignment component 22 have the same structure and both include a first moving block 211, a first alignment cylinder 212 disposed on the first moving block 211, and a first alignment wheel 213 driven by the first alignment cylinder 212 to move up and down. The left alignment component 23 and the right alignment component 24 have the same structure and both include a second moving block 231 and a second alignment wheel 232 disposed on the second moving block 231.

[0057] In this embodiment, both the third linear drive module 25 and the fourth linear drive module 26 are driven by servo motors via transmission belts. The first moving block 211 and the second moving block 231 are mounted on the transmission belt, thereby driving the front alignment component 21, the rear alignment component 22, the left alignment component 23, and the right alignment component 24 to move. This allows for adaptation to photovoltaic modules of different widths and lengths, improving the versatility of the installation equipment. In other embodiments, both the third linear drive module 25 and the fourth linear drive module 26 can be mounted on linear motors, which directly drive the front alignment component 21, the rear alignment component 22, the left alignment component 23, and the right alignment component 24. The third linear drive module 25 and the fourth linear drive module 26 can also be configured with other drive structures, which are not limited here.

[0058] The film feeding device 3 includes a film feeding mechanism 3a and a support platform 3b disposed beside the film feeding mechanism for placing the cut film. In this embodiment, four film feeding mechanisms 3a are provided and located at the four corners of the conveying device 1. Correspondingly, four support platforms 3b are provided and located on the four sides of the photovoltaic module.

[0059] Specifically, the film feeding mechanism 3a includes a mounting bracket 311, a feeding module 31, a buffer module 32, a film pressing assembly 33, a feeding module 34, a peeling assembly 39, a detection module 35, a clamping assembly 36, and a cutting assembly 37, which are sequentially arranged on the mounting bracket 311. Below the peeling assembly 39, there is also a collection module 310 for collecting release paper. The feeding module 34 and the collection module 310 are driven by a drive module 38 to respectively perform the actions of feeding film and collecting release paper. When the cutting component 37 cuts the film, the clamping component 36 needs to clamp the film first. To avoid excessive stretching of the film when clamping, the detection module 35 detects the tension of the film. The detection module 35 is located between the feeding module 34 and the clamping component 36. The feeding module 34 and the clamping component 36 are electrically connected to the detection module 35. The detection module 35 receives the electrical signal from the clamping component 36 to detect the tension of the film. The feeding module 34 adjusts the unwinding speed of the film according to the electrical signal from the detection module 35. If the film is detected to be in a relaxed state, it is determined that the film is not excessively stretched; if the film is detected to be in a taut state, it is determined that the film is excessively stretched. The feeding module 34 then continues to feed a section of film forward to relax the film at the clamping component 36.

[0060] The adhesive film is released from the feeding module 31 and passes through the buffer module 32, the film pressing component 33, the feeding module 34, the peeling component 39, and the detection module 35 in sequence. After the pulling module 320 pulls out the adhesive film of a set length, the clamping component 36 clamps the adhesive film, while the film pressing component 33 presses down on the adhesive film. The cutting component 37 cuts the adhesive film, and the pulling module 320 continues to pull out the adhesive film and places it on the carrying platform 3b, waiting for the adhesive film laying mechanism 4 to take away the adhesive film for laying.

[0061] The feeding module 31 includes a feeding motor 312 mounted on a mounting bracket 311, a feeding rotating shaft 313 driven by the feeding motor 312, a film roll 314 mounted on the feeding rotating shaft 313, and several first guide wheels 315 that guide the film on the film roll 314 to the buffer module 32 and then feed it onto the feeding module 33. The mounting bracket 311 is also provided with guide members 318 that guide the film roll 314 onto the first guide wheels 315. The left and right ends of the film roll 314 are restricted from sliding axially along the feeding rotating shaft 313 by limiting rings 316. The limiting rings 316 are mounted on the ends of the feeding rotating shaft 313 by fasteners 317. When the film roll 314 needs to be replaced, the fasteners can be loosened. The limiting ring 316 ensures that the film roll 314 can only rotate on the feeding rotation shaft 313 and cannot move around the circumference of the feeding rotation shaft 313, thus ensuring the accuracy of feeding.

[0062] The buffer module 32 includes a slide rail 321 vertically mounted on a mounting bracket 311, a counterweight 322 slidably mounted on the slide rail 321, a plurality of buffer rollers 323 mounted on the counterweight 322, a sensing plate 324 fixed to one side of the counterweight 322, a plurality of sensor groups 325 arranged along the length of the slide rail 321 and detecting the sensing plate 324, and a limiting member 326 located at the bottom of the slide rail 321 and limiting the lower position of the counterweight 322. An adhesive film is wound around the buffer rollers 323 and the first guide wheel 315. In this embodiment, two buffer rollers 323 are provided. In other embodiments, the number of buffer rollers 323 can be set according to actual conditions, and is not limited here.

[0063] In this embodiment, the sensor group 325 includes, from bottom to top, a first sensor 3251, a second sensor 3252, a third sensor 3253, and a fourth sensor 3254. The sensor group allows for precise control of the unwinding speed of the unwinding motor 312 in the unwinding module 31. The first sensor 3251 is a spare, and the second sensor 3252 serves as the stop signal for the unwinding motor 312. If the second sensor 3252 detects a signal from the sensing plate 324 on the counterweight block 322, the unwinding motor 312 stops unwinding. If the buffer roller 133 reaches the position of the fourth sensor 3254 during unwinding, it indicates that the buffer amount has decreased, and the unwinding motor 312 accelerates the unwinding speed. If the buffer roller 133 reaches the position of the third sensor 3253, it indicates that the buffer amount has increased, and the unwinding motor 122 slows down the unwinding speed. In this way, the roll material is always controlled between the second sensor 3252 and the fourth sensor 3254, preventing the roll material from unwinding too quickly or too slowly, ensuring constant tension during the conveying of the film belt, and preventing the film from being excessively stretched and deformed. The unwinding speed of the unwinding motor 312 is set according to actual conditions and is not limited here.

[0064] In other embodiments, the number of sensors in the sensor group 325 can be set according to actual conditions, and the working signal of each sensor can be set according to actual conditions. The working signals include a stop signal, a feeding speed-up signal, a feeding speed-down signal, etc.

[0065] When the buffer module 32 is buffering the adhesive film, the counterweight 322 and the buffer roller 323 in the buffer module 32 will move up and down, thereby driving the adhesive film to move up and down. Therefore, a film pressing component 33 is provided. When the feeding module 34 does not need to feed, the film pressing component 33 presses down the adhesive film, and the buffer module 32 can buffer the adhesive film, which can prevent the output adhesive film from being pulled back and prevent the adhesive film from being excessively stretched and deformed.

[0066] The film pressing assembly 33 includes a film pressing cylinder 331 mounted on the mounting bracket 311, a pressing block 332 driven by the film pressing cylinder 331 to move up and down and pressing on the upper surface of the adhesive film, and a first support block 333 supported at the bottom of the adhesive film. The pressing block 332 is made of soft materials such as plastic or rubber to avoid damaging the adhesive film. The specific material of the pressing block 332 is not limited here.

[0067] The feeding module 34 includes a film support frame 344 supporting the film, a first rotating shaft 341 rotatably mounted on a mounting bracket 311, a drive roller 342 mounted on the first rotating shaft 341, a driven roller 343 located directly below the drive roller 342 and cooperating with the drive roller 342 to clamp the film for feeding, and a swing drive assembly 345 that drives the driven roller 343 to swing closer to or away from the drive roller 342. The swing drive assembly 345 includes a support shaft 3451 mounted on the film support frame 344, a swing bracket 3452 rotatably mounted on the support shaft 3451 at one end, and a first cylinder 3453 that drives the swing bracket 3452 to swing left and right. The driven roller 343 is connected to the other end of the swing bracket 3452. The swing bracket 3452 has a downward-extending actuating part 3454 that powers the first cylinder 3453. When the first cylinder 3453 extends upward, the swing bracket 3452 swings to the upper left to a set position, causing the driven roller 343 to approach the driving roller 342 and cooperate with it to achieve the feeding action. During feeding, the first cylinder 3453 is in the extended state, causing the driven roller 343 to approach the driving roller 342 to cooperate with the feeding. If it is necessary to pass the material between the driven roller 343 and the driving roller 342 at the beginning, the first cylinder 3453 retracts, and the swing bracket 3452 automatically swings to the lower right, causing the driven roller 343 to move away from the driving roller 342, thereby enabling the film to pass smoothly between the driven roller 343 and the driving roller 342.

[0068] Since the adhesive film is attached to the release paper, a peeling assembly 39 is provided to separate the adhesive film from the release paper. The peeling assembly 39 is positioned between the feeding module 34 and the detection module 35. Several second guide wheels 330 are also provided between the peeling assembly 39 and the feeding assembly 34 to guide the adhesive film. The peeling assembly 39 includes a pressing block 391 pressing the adhesive film above and a peeling plate 392 positioned below the pressing block 391. A first gap is provided between the pressing block 391 and the peeling plate 392 for the adhesive film to pass through. The peeling plate 392 has a peeling blade at one end facing the clamping assembly 36. The release paper is rolled up and wound onto the collecting module 310 in the opposite direction, while the adhesive film enters the clamping assembly 36.

[0069] The detection module 35 includes a second cylinder 351 mounted on a mounting bracket 311, a bracket 352 driven by the second cylinder 351 to move up and down, and a probe 353 mounted on the bracket 352 for detecting the adhesive film.

[0070] The clamping assembly 36 includes a clamping cylinder 361 and a pair of first grippers 362 that are driven by the clamping cylinder 361 to open or clamp.

[0071] The cutting assembly 37 includes a third cylinder 371, a cutting moving plate 372 driven by the third cylinder 371 to move closer to or away from the adhesive film, and cutting scissors 373 disposed on the cutting moving plate 372.

[0072] The material pulling module 320 includes a fifth linear drive module 3201, a fourth cylinder 3202 driven by the fifth linear drive module 3201 to move closer to or away from the clamping assembly 36, and a pair of second grippers 3203 driven by the fourth cylinder 3202 to clamp or open. The fifth linear drive module 3201 can be configured as a linear drive motor or as a motor-driven belt conveyor; the specific configuration of the fifth linear drive module 3201 is not limited here.

[0073] The detection principle of the detection module 35 is as follows: After the pulling module 320 pulls the film out to a set length, the pair of first grippers 362 of the clamping component 36 clamp the film, and the cutting component 37 performs a cutting action on it. At the same time, the detection module 35 starts to work, and the second cylinder 351 drives the probe 353 to descend. If the probe 353 cannot sense the film, it is determined that the film is in a taut state and is considered not to be overstretched, which meets the requirements. If the probe 353 can sense the film, it is determined that the film is in a taut state and is considered to be overstretched. Then the feeding module 34 continues to feed a section of film forward, so that the film at the clamping component 36 is in a relaxed state, which can avoid the film being overstretched and deformed. Therefore, this solution can be applied to the feeding of highly elastic films and can also avoid the problem of the film being stretched and deformed.

[0074] The collecting module 310 includes a second rotating shaft 3101 rotatably mounted on a mounting bracket 311 and a damper 3102 connected to one end of the second rotating shaft 3101. The other end of the damper 3102 is connected to a take-up shaft 3103. A pair of limiting plates 3104 are provided on the outer periphery of the take-up shaft 3103 to limit the two sides of the release paper. When the second rotating shaft 3101 rotates to collect the material, the rotational resistance is usually small. Due to the rotational inertia of the second rotating shaft 3101, the collecting speed may be unstable. The damper 3102 can provide a certain resistance, so that the take-up shaft 3103 has a certain resistance when rotating relative to the second rotating shaft 3101, which can prevent the take-up shaft 3103 from tearing the adhesive film or release paper due to excessive rotational inertia.

[0075] The drive module 38 is disposed on the back of the mounting bracket 311. The drive module 38 includes a servo motor 381 mounted on the mounting bracket 311 and a third rotating shaft 382 driven by the servo motor 381 to rotate. A first transmission wheel 383 is disposed on the third rotating shaft 382, ​​a second transmission wheel 384 is disposed on the second rotating shaft 3101, and a third transmission wheel 385 and a fourth transmission wheel 386 are disposed at one end of the first rotating shaft 341. A first transmission wheel 383 and a fourth transmission wheel 386 are wound around the first transmission wheel 383 and the third transmission wheel 385. A transmission belt 387 enables rotational transmission between the third rotating shaft 382 and the first rotating shaft 341. A second transmission belt 388 is wound around the second transmission wheel 384 and the fourth transmission wheel 386 to enable rotational transmission between the second rotating shaft 3101 and the first rotating shaft 341.

[0080] The first support plate 43, the laying unit 41 and the bending and shaping unit 42 are jointly set on the first support plate 43.

[0081] In actual operation, the air blowing component 424 is located on the outside of the photovoltaic module.

Gears 4113 are provided at both ends of the fourth rotating shaft 4112, and a rack 4114 that cooperates with the gears 4113 for transmission is provided on the lifting frame 412.

[0087] In this embodiment, four film laying mechanisms 4 are provided, all of which have the same or similar structure and are located on the four sides of the photovoltaic module. The four film laying mechanisms 4 are the front film laying mechanism 4a, the rear film laying mechanism 4b, the left film laying mechanism 4c, and the right film laying mechanism 4d, which lay film on the front, rear, left, and right sides of the photovoltaic module respectively.

[0088] The front film laying mechanism 4a and the rear film laying mechanism 4b are jointly driven by a first linear drive module 6 to move back and forth, simultaneously approaching or moving away from the photovoltaic module. The left film laying mechanism 4c and the right film laying mechanism 4d are jointly driven by a second linear drive module 7 to move left and right, simultaneously approaching or moving away from the photovoltaic module. The first linear drive module 6 and the second linear drive module 7 are arranged perpendicularly to each other. This perpendicular arrangement not only enables the film transfer movement but also accommodates films of different lengths and widths, improving the versatility of the laying equipment.

[0089] In this embodiment, the first linear drive module 6 includes a first motor 61, a first axle wheel assembly 62 driven by the first motor 61 to rotate, and a third transmission belt 63 wound around the first axle wheel assembly 62. The third transmission belt 63 has two sections that extend in the front-rear direction. The front end of the first transmission belt 253 is provided with a front adhesive film laying mechanism 4a and the rear end is provided with a rear adhesive film laying mechanism 4b. The first support plates 43 of the front adhesive film laying mechanism 4a and the rear adhesive film laying mechanism 4b are both mounted on the third transmission belt 63 by a first belt clamp.

The fourth transmission belt 73 has two sections and extends in the left-right direction. A left film laying mechanism 4c is provided on the left side of the first transmission belt 253, and a right film laying mechanism 4d is provided on the right side. The first support plates 43 of the left film laying mechanism 4c and the right film laying mechanism 4d are both mounted on the fourth transmission belt 73 by a second belt clamp.

The first linear drive module 6 and the second linear drive module 7 can also be configured with other drive structures, which are not limited here.

[0092] When using the film laying mechanism and film laying equipment 100 provided in this solution, the photovoltaic modules flow into the conveying device 1. The alignment mechanism 2 aligns the photovoltaic modules on all four sides. The film feeding devices 3 at the four corners of the photovoltaic modules work simultaneously. The film is released from the feeding module 31 and passes through the buffer module 32, the pressing module 33, the feeding module 34, the peeling module 39, and the detection module 35 in sequence. After the pulling module 320 pulls out the film of a set length, the clamping component 36 clamps the film, and at the same time, the pressing component 33 presses down on the film for cutting. Component 37 cuts the adhesive film, and the pulling module 320 continues to pull out the adhesive film and place it on the support platform 3b. The front adhesive film laying mechanism 4a, rear adhesive film laying mechanism 4b, left adhesive film laying mechanism 4c, and right adhesive film laying mechanism 4d on the four sides of the photovoltaic module work simultaneously, all moving to the corresponding support platform 3b. The four laying units 41 start working simultaneously, and the lifting drive module 411 drives the lifting frame 412 to descend. Several adsorption components 413 simultaneously adsorb the adhesive film. The lifting drive module 411 drives the lifting frame 412 to descend. As the photovoltaic module rises, the first linear drive module 6 drives the front film laying mechanism 4a and the rear film laying mechanism 4b to move simultaneously to the front and rear sides of the photovoltaic module. The suction element 413 of the laying unit 41 breaks the vacuum and places the film onto the edge of the photovoltaic module. Simultaneously, the second linear drive module 7 drives the left film laying mechanism 4c and the right film laying mechanism 4d to move to the left and right sides of the photovoltaic module. The suction element 413 of the laying unit 41 breaks the vacuum and places the film onto the edge of the photovoltaic module. All four laying units 41 stop working, and... The lifting drive module 411 drives the lifting frame 412 to rise, and the four bending and shaping units 42 start working simultaneously. The first drive component 421 drives the first mounting frame 422 to fall, so that the heating component 423 and the blowing component 424 approach the adhesive film. The blowing component 424 aligns with the outer adhesive film to bend it and cover the side of the photovoltaic module. The heating component 423 aligns with the adhesive film to firmly stick the adhesive film to the upper surface and side of the photovoltaic module. The adhesive film laying is completed, and the photovoltaic module flows out of the conveying device 1 and continues to flow into new photovoltaic modules for adhesive film laying.
