Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic equipment, and in particular relates to a laminating device and a laminating method for photovoltaic components. Background Art

[0002] The photovoltaic module laminating device is mainly used to press and solidify the various layers of photovoltaic modules. When working, the photovoltaic panels need to be placed on the conveyor table, and the photovoltaic panels are transported to the inside of the laminating device through the conveyor table. After the special glue for photovoltaic panel lamination is applied on the top of the photovoltaic panel below, the upper photovoltaic panel is placed on the lower photovoltaic panel and a certain pressure is applied, and then laminated to form a set of photovoltaic modules.

[0003] In the prior art, to improve the stability of the connection between the upper and lower photovoltaic panels, a full coating of glue is typically applied to the lower photovoltaic panel. However, since the lower photovoltaic panel is heavily coated with glue, during the lamination process, a large amount of glue overflows from the joints around the photovoltaic panels. This overflow easily flows onto the non-adhesive surfaces of the upper and lower photovoltaic panels, requiring subsequent cleaning of the glue from the photovoltaic module, which in turn increases the workload of the photovoltaic module manufacturing process. To address this issue, we provide a photovoltaic module lamination device and method to address this issue. Summary of the Invention

Since the surface of the lower photovoltaic panel is coated with a large amount of glue, during the lamination process of the upper and lower photovoltaic panels, a large amount of glue overflows from the intersection gaps around the photovoltaic panels. The overflowed glue easily flows to the non-adhesive surfaces of the upper and lower photovoltaic panels, resulting in the need to clean the glue on the photovoltaic module later, thereby increasing the workload of photovoltaic module processing.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] For specific embodiment 1, please refer to Figure 1-14 The present invention is a laminating device for photovoltaic modules, comprising a guide bearing mechanism 1, a gluing mechanism 2, a glue cylinder lifting mechanism 3, a photovoltaic panel conveying mechanism 4 and a glue scraping control mechanism 6; the guide bearing mechanism 1 comprises a bearing frame 101, and two guide rails 102 are symmetrically fixed inside the bearing frame 101; the gluing mechanism 2 is mounted on the front side of the bearing frame 101, and the gluing mechanism 2 comprises a hollow glue cylinder 201, and an axially arranged glue notch is provided at the bottom of the hollow glue cylinder 201; the glue cylinder lifting mechanism 3 is symmetrically arranged inside the bearing frame 101 and slidably cooperates with the bearing frame 101, and the glue cylinder lifting mechanism 3 comprises an extrusion lifting shaft 301 rotatably arranged inside the bearing frame 101, and the gluing mechanism 2 transmission sleeve is arranged on the two extrusion lifting shafts 301, and the rotation of the extrusion lifting shaft 301 realizes the gluing. The glue coating mechanism 2 now moves up and down; the photovoltaic panel conveying mechanism 4 is slidably arranged between the two guide rails 102, and the photovoltaic panel conveying mechanism 4 includes a negative pressure adsorption platform 401, and the negative pressure adsorption platform 401 is used to negatively adsorb the photovoltaic panel 5, and the photovoltaic panel conveying mechanism 4 moves to horizontally squeeze the glue cylinder lifting mechanism 3 on both sides, so that the extrusion lifting shafts 301 on both sides rotate synchronously to realize the downward movement of the hollow glue coating cylinder 201 close to the photovoltaic panel 5; the glue scraping control mechanism 6 is installed on the rear side of the supporting frame 101, and the glue scraping control mechanism 6 includes a glue scraping control assembly 7, and the glue scraping control assembly 7 includes multiple groups of glue scraping parts, each group of glue scraping parts consists of a first glue scraping part 701 and a second glue scraping part 702, and the first glue scraping part 701 and the second glue scraping part 702 are respectively used to scrape off the overflowed glue on different sides of the photovoltaic panel 5.

[0035] In this embodiment of the present invention, a traveling gear seat 103 located below the guide rail 102 is fixed inside the carrying frame 101, two limiting grooves 104 are symmetrically opened inside the carrying frame 101, and a positioning frame 105 is fixedly provided at the front end of the two guide rails 102. A glue storage box 106 is installed on the top of the carrying frame 101, and the liquid outlet of the glue storage box 106 is connected to a first glue outlet pipe 107. A second glue outlet pipe 108 is slidably provided on the first glue outlet pipe 107, and the second glue outlet pipe 108 is connected to the hollow The glue coating cylinder 201 is connected, and a control valve 109 is installed on the first glue outlet pipe 107. When controlling the up and down movement of the hollow glue coating cylinder 201, the second glue outlet pipe 108 is always sleeved on the first glue outlet pipe 107 and does not separate. After opening the control valve 109, the glue in the glue storage box 106 can flow along the first glue outlet pipe 107 and the second glue outlet pipe 108 into the hollow glue coating cylinder 201, thereby realizing the replenishment of glue in the hollow glue coating cylinder 201.

[0036] In this embodiment of the present invention, the gluing mechanism 2 also includes two lifting guide frames 202 symmetrically mounted on the carrier frame 101. The lifting guide frames 202 are slidably sleeved on the corresponding extrusion lifting shafts 301. A spiral groove 302 is provided on the side surface of the extrusion lifting shaft 301. A sliding member that fits inside the spiral groove 302 is fixed inside the sleeve on the lifting guide frame 202. The hollow gluing cylinder 201 is fixed between the two lifting guide frames 202. Through the above-mentioned specific structural design, when the extrusion lifting shaft 301 is controlled to rotate, the sliding member can be driven to slide along the corresponding spiral groove 302, thereby driving the two lifting guide frames 202 to move up and down synchronously. During this process, each lifting guide frame 202 will not rotate.

[0037] In this embodiment of the present invention, the rubber cylinder lifting mechanism 3 also includes a double-slope moving plate 303, a transmission tooth plate 304 is fixedly installed on the side of the double-slope moving plate 303 close to the extrusion lifting shaft 301, and a transmission gear 305 fixedly installed on the side of the extrusion lifting shaft 301 is meshed with the corresponding transmission tooth plate 304. A support frame 306 is fixedly provided between the double-slope moving plate 303 and the corresponding transmission tooth plate 304, and the support frame 306 is slidably connected to the corresponding limit groove 104. A first elastic member 307 connected to the support frame 306 is installed. When the double-slant moving plate 303 is pushed, it will move horizontally toward the extrusion lifting shaft 301. The support frame 306 that moves synchronously with the double-slant moving plate 303 will gradually compress the first elastic member 307, and the transmission gear plate 304 that moves synchronously with the double-slant moving plate 303 drives the transmission gear 305 to rotate, and then drives each extrusion lifting shaft 301 to rotate, thereby realizing the synchronous up and down movement of the two lifting guide frames 202.

[0038] The top of the conveying base 402 is provided with a support plate 403, and the negative pressure adsorption platform 401 is fixedly installed on the top of the support plate 403. The bottom of the negative pressure adsorption platform 401 is fixedly installed with a hollow negative pressure part 404. The top of the negative pressure adsorption platform 401 is provided with a negative pressure slot 405 connected to the hollow negative pressure part 404. The top of the conveying base 402 is provided with a negative pressure generator 406 connected to the hollow negative pressure part 404. After the photovoltaic panel 5 is placed on the top of the negative pressure adsorption platform 401, the negative pressure generator 406 is started to form a negative pressure environment inside the hollow negative pressure part 404. Then, under the action of the negative pressure, the photovoltaic panel 5 is tightly adsorbed and fixed on the negative pressure adsorption platform 401, ensuring that the photovoltaic panel 5 on the negative pressure adsorption platform 401 will not deviate during the lamination process. The travel control motor 407 and the travel control motor 407 output shaft are connected to the travel gear 408 meshing with the travel gear seat 103. After the travel control motor 407 is started, the travel gear 408 is controlled to roll along the travel gear seat 103, thereby realizing the sliding of the entire photovoltaic panel conveying mechanism 4 along the extension direction of the guide rail 102. The conveying base 402 is fixedly installed with double-slanted pushing seats 409 on opposite sides. When the photovoltaic panel conveying mechanism 4 is in the initial position close to the positioning frame 105, a photovoltaic panel 5 is placed on the top of the negative pressure adsorption platform 401, and the position of the photovoltaic panel 5 on the negative pressure adsorption platform 401 is adjusted so that the photovoltaic panel 5 is attached to the inner wall of the positioning frame 105. At this time, the photovoltaic panel 5 is adsorbed and fixed on the top of the negative pressure adsorption platform 401 by negative pressure, and the photovoltaic panel 5 adsorbed by negative pressure is just in the center position of the negative pressure adsorption platform 401, thereby quickly realizing the precise positioning of the photovoltaic panel 5 on the negative pressure adsorption platform 401.

[0039] In this embodiment of the present invention, the scraper control assembly 7 also includes a horizontal fixed frame 703 fixedly mounted on one side of the supporting frame 101, a limiting guide rod 704 is slidably provided on the horizontal fixed frame 703, a first U-shaped frame 705 is fixedly provided on the end of the limiting guide rod 704, and the output end of the scraper control motor 706 installed on the horizontal fixed frame 703 is connected to the scraper control screw 707, the first U-shaped frame 705 is sleeved on the scraper control screw 707 and the two are threadedly matched; two L-shaped mounting frames 708 are symmetrically fixed on one side of the first U-shaped frame 705 away from the horizontal fixed frame 703, a first glue collection box 709 is provided on the inner side of the L-shaped mounting frame 708, the spacing between the two first glue collection boxes 709 is the same as the length of the photovoltaic panel 5, the first scraper member 701 and the second scraper member 702 are respectively fixed on the upper and lower sides of the first glue collection box 709.

[0040] The top of the first glue collection box 709 is respectively provided with a first glue collection port 710 and an inclined glue guide plate 711. A connecting rod that slides through the L-shaped mounting bracket 708 is fixed on the top of the first glue collection box 709. A second U-shaped bracket 712 fixed with each connecting rod is provided above the first U-shaped bracket 705. A hydraulic cylinder 713 is installed on the side of the first U-shaped bracket 705 close to the horizontal fixing bracket 703. The output end of the hydraulic cylinder 713 is connected to the second U-shaped bracket 712. In the initial state, the first U-shaped bracket 705 and each component thereon between the limiting guide rod 704 and the scraping glue control screw 707 are The first U-shaped frame 705 and the various components thereon will not interfere with the movement of the photovoltaic panel conveying mechanism 4 on the guide rail 102. That is, the first U-shaped frame 705 and the various components thereon are in a horizontally dislocated position relationship with the guide rail 102 at the beginning. When the scraper control motor 706 is started to drive the scraper control screw 707 to rotate, the first U-shaped frame 705 and the various components thereon can be driven to move horizontally close to the top of the guide rail 102 until the first U-shaped frame 705 and the various components thereon move to the lamination station (such as Figure 1 shown).

[0041] In this embodiment of the present invention, the scraping control mechanism 6 also includes a glue collecting component 8; wherein the glue collecting component 8 includes two second glue collecting boxes 801 that are symmetrically arranged and have a semicircular structure, and the spacing between the two second glue collecting boxes 801 is the same as the width of the photovoltaic panel 5. A second glue collecting port 802 that is connected to its inner cavity is opened on one side of the second glue collecting box 801, wherein a first connecting frame 803 is installed on one second glue collecting box 801, and a second connecting frame 804 is installed on the other second glue collecting box 801. The first connecting frame 803 is fixedly installed on the horizontal fixing frame 703, and the second connecting frame 804 is fixedly connected to the corresponding guide rail 102. Through the above structure, the two second glue collecting boxes 801 are stably installed on both sides of the laminating station; after a photovoltaic panel 5 is negatively adsorbed on the top of the negative pressure adsorption platform 401, the controller starts the travel control motor 407 and controls the travel gear 408 to roll along the travel gear seat 103, so that the entire photovoltaic panel conveying mechanism 4 slides along the guide rail 102 toward the laminating station. When the inclined portion at the front end of the double-slope pushing seat 409 abuts against the inclined portion at the rear end of the double-slope moving plate 303, the double-slope pushing seat 409 that continues to move squeezes the corresponding double-slope moving plate 303, causing the double-slope moving plates 303 on both sides to move horizontally away from each other, and the support frame 306 that moves synchronously with the double-slope moving plate 303 gradually compresses the first elastic member 307, and the transmission tooth plate 304 that moves synchronously with the double-slope moving plate 303 drives the transmission gear 305 to rotate, thereby driving Each extrusion lifting shaft 301 rotates, thereby enabling the two lifting guide frames 202 to move downward synchronously. When the inclined portion at the front end of the double-slope pushing seat 409 just breaks away from the inclined portion at the rear end of the double-slope moving plate 303 (the hollow glue coating cylinder 201 is close to the photovoltaic panel 5 below it, and the front end of the photovoltaic panel 5 just exceeds the hollow glue coating cylinder 201 by a small distance), the double-slope pushing seat 409 slides along the double-slope moving plate 303, and the first elastic member 307 cannot rebound and reset at this time.

[0042] During the sliding of the double-slanted pushing seat 409 along the double-slanted moving plate 303, the photovoltaic panel conveying mechanism 4 carrying the photovoltaic panel 5 continues to approach the laminating station, and the glue in the hollow glue coating cylinder 201 gradually flows out along the glue coating groove at its bottom and is coated on the top of the photovoltaic panel 5 (the length of the glue coating groove on the hollow glue coating cylinder 201 is less than the width of the photovoltaic panel 5). When the rear end of the photovoltaic panel 5 is close to the hollow glue coating cylinder 201 (that is, the rear end of the photovoltaic panel 5 has not passed through the hollow glue coating cylinder 201 at this time, and the distance between the rear end of the photovoltaic panel 5 and the hollow glue coating cylinder 201 is basically the same as the distance between the front end of the photovoltaic panel 5 and the hollow glue coating cylinder 201. This non-full coating method can save glue consumption and avoid glue waste, and at the same time reduce the amount of glue overflow around the lamination process), stop the glue coating groove at the bottom of the hollow glue coating cylinder 201 to continue to discharge glue, and then continue to control the photovoltaic panel conveying mechanism 4 carrying the photovoltaic panel 5 to move towards the lamination station. After the cam 310 is in the process of being reset, the double-slope movable plates 303 on both sides are reset, and the transmission gear plate 304 that moves synchronously with the double-slope movable plates 303 drives the transmission gear 305 to rotate in the opposite direction, thereby driving each extrusion lifting shaft 301 to rotate in the opposite direction, thereby realizing that the two lifting guide frames 202 can be synchronously moved upward and reset, and the hollow glue coating cylinder 201 returns to the initial position.

[0043] Then, the controller starts the scraping control motor 706 to drive the scraping control screw 707 to rotate, driving the first U-shaped frame 705 and the various components thereon to move horizontally close to the top of the guide rail 102 until the first U-shaped frame 705 and the various components thereon move to the lamination station. At this time, the first glue collection box 709 is attached to the front and back sides of the photovoltaic panel 5, and the second glue collection box 801 is attached to the left and right sides of the photovoltaic panel 5, that is, glue collection boxes are arranged all around the photovoltaic panel 5, and the inclined glue guide plate 711 is close to the bottom of the intersection gap on the front and back sides, and the intersection gap on the left and right sides is completely inside the second glue collection port 802, and then the upper photovoltaic panel 5 is accurately pressed onto the lower photovoltaic panel 5 by the intelligent robotic arm. After completing the lamination processing of the photovoltaic module, the intelligent robotic arm automatically rotates and resets (conventional machinery on the intelligent robotic arm production line, which belongs to the prior art and will not be described in detail here).

[0044] Subsequently, the scraping control motor 706 drives the scraping control screw 707 to rotate in the opposite direction, driving the first U-shaped frame 705 and the various components thereon to move horizontally away from the lamination station until the first U-shaped frame 705 and the various components thereon return to the initial position. In this process, the overflowing glue at the intersection of the front and rear sides of the photovoltaic module is scraped off by the first scraping member 701, and the scraped overflowing glue enters the first glue collection box 709 along the inclined glue guide plate 711 and the first glue collection port 710 for collection. Then, the scraping control motor 706 drives the scraping control screw 707 to rotate in the positive direction again. The first U-shaped frame 705 and the components thereon are rotated to the laminating station again, and the hydraulic cylinder 713 is started to drive the second U-shaped frame 712 to move upward to the specified position. Under the action of the second U-shaped frame 712, the first glue collection boxes 709 on the front and rear sides are driven to move upward, so that the first glue collection boxes 709 on the front and rear sides are misaligned with the photovoltaic components. At this time, the second glue scraper 702 is located on the left and right sides of the photovoltaic component. Then, the photovoltaic panel conveying mechanism 4 carrying the photovoltaic component is continued to be controlled to move forward, and the overflowing glue is scraped by the second glue scraper 702 into the second glue collection box 801 for collection.

[0045] When the laminated photovoltaic module leaves the lamination station and one end of the photovoltaic module rests on the conveyor belt (a belt transmission system is installed at the rear end of the guide rail 102), the negative pressure adsorption of the photovoltaic module is released by the negative pressure generator 406, and then the photovoltaic module is transported to the back-end process through the operation of the conveyor belt. Then, the scraper control motor 706 drives the scraper control screw 707 to rotate in the opposite direction, so that the first U-shaped frame 705 and the various components thereon return to the initial position, and then the hydraulic cylinder 713 drives the second U-shaped frame 712 to move downward to complete the reset (the first glue collection boxes 709 on both sides return to the initial position), and then the walking control motor 407 controls the walking gear 408 to roll in the opposite direction along the walking gear seat 103 until the unloaded photovoltaic panel conveying mechanism 4 returns to the initial position. Subsequently, the lamination processing of the photovoltaic modules can be successively realized according to the same operation method as above.

[0046] Specific embodiment 2, on the basis of specific embodiment 1, an L-shaped engaging portion 110 is slidably provided on the carrying frame 101, a movable connecting plate 111 is fixed to the top of the L-shaped engaging portion 110, a fixed connecting plate 112 is installed on the top of the carrying frame 101, a second elastic member 113 is provided between the fixed connecting plate 112 and the movable connecting plate 111, a movable connecting plate 111 is fixed with a movable rod that slides through the fixed connecting plate 112, a magnet disk 114 is installed at the end of the movable rod, and an electromagnet that magnetically repels the magnet disk 114 is installed on the surface of the fixed connecting plate 112;

[0047] A support ring 203 and a pass / close control gear ring 204 are rotatably mounted on the hollow glue coating cylinder 201. An arc-shaped sealing plate 205 attached to the outer wall of the hollow glue coating cylinder 201 is fixed between the support ring 203 and the pass / close control gear ring 204. In the initial state, the arc-shaped sealing plate 205 seals the glue coating groove. The pass / close control gear ring 204 is engaged with the L-shaped meshing portion 110. In the initial state, under the strong elastic force of the second elastic member 113, the L-shaped meshing portion 110 is tightly engaged with the pass / close control gear ring 204, and the magnet disk 114 is tightly attached to the fixed connection. On the plate 112, an elastic reset ring 206 is fixed on the surface of one of the lifting guide frames 202, and the support ring 203 is arranged inside the elastic reset ring 206. The first ear plate fixed on the side surface of the support ring 203 and the second ear plate fixed inside the elastic reset ring 206 are connected by an arc-shaped elastic member (similar to the reset function of a torsion spring). When the arc-shaped sealing plate 205 rotates and releases the meshing effect of the L-shaped meshing part 110 on the opening and closing control gear ring 204, the arc-shaped elastic member can make the arc-shaped sealing plate 205 rotate in the opposite direction and reset to re-seal the glue coating groove.

[0048] In this embodiment of the present invention, the present invention also includes a glue discharge control mechanism 9; wherein, the glue discharge control mechanism 9 includes two symmetrically arranged L-shaped support seats 901, the L-shaped support seats 901 are fixedly connected to the corresponding lifting guide frames 202, and a glue discharge control screw 902 is rotatably arranged between the L-shaped support seats 901, and the output end of the glue discharge control motor 903 installed on the surface of one of the L-shaped support seats 901 is connected to the glue discharge control screw 902, and two moving parts 904 are symmetrically threaded on the glue discharge control screw 902, and a push-pull rod 905 fixed on the surface of the moving part 904 slides through the interior of the hollow glue coating cylinder 201, and a glue pushing piston 906 is installed at the end of the push-pull rod 905.

[0049] When the double-slanted movable plates 303 on both sides move horizontally away from each other, the downwardly moving hollow glue coating cylinder 201 drives the opening and closing control gear ring 204 to move downward synchronously. During the downward movement of the opening and closing control gear ring 204, it rolls along the L-shaped meshing portion 110, causing the arc-shaped blocking plate 205 to gradually deviate from the glue coating slot until the hollow glue coating cylinder 201 is close to the photovoltaic panel 5 below it. At this time, the arc-shaped blocking plate 205 releases the blockage of the glue coating slot. Then, while the photovoltaic panel 5 continues to move forward, the glue discharging control motor 903 controls the glue discharging control screw 902 to rotate, so that the two glue pushing pistons 906 inside the hollow glue coating cylinder 201 are close to each other, thereby driving the glue in the hollow glue coating cylinder 201 to gradually flow out along the glue coating slot and coat the top of the photovoltaic panel 5. When the rear end of the photovoltaic panel 5 is close to the hollow glue coating cylinder 201, while controlling the two glue pushing pistons 906 to move away from each other and reset, the glue discharging control motor 903 controls the two glue pushing pistons 906 to move away from each other and reset. When the electromagnet on the fixed connecting plate 112 is energized, it generates a magnetic repulsion force on the magnet disk 114, thereby causing the L-shaped meshing portion 110 to move away from the on-off control tooth ring 204 (the second elastic member 113 is in a compressed state at this time). At this time, under the action of the arc-shaped elastic member, the arc-shaped sealing plate 205 rotates in the opposite direction and resets to re-seal the glue coating groove. After the unloaded photovoltaic panel conveying mechanism 4 returns to the initial position, the electromagnet on the fixed connecting plate 112 is controlled to be de-energized and demagnetized to release the magnetic repulsion force on the magnet disk 114. Under the action of the elastic restoring force of the second elastic member 113, the L-shaped meshing portion 110 is reset and re-engaged with the on-off control tooth ring 204. The controller opens the control valve 109, so that the glue in the glue storage box 106 can flow into the hollow glue coating cylinder 201 along the first glue outlet pipe 107 and the second glue outlet pipe 108, thereby realizing the replenishment of glue in the hollow glue coating cylinder 201.

8. The laminating method of a photovoltaic module laminating device according to claim 7, characterized in that: The steps include: S01. After a photovoltaic panel is negatively pressured and adsorbed on the top of the negative pressure adsorption platform, the entire photovoltaic panel conveying mechanism is controlled to slide along the guide rail toward the laminating station. When the inclined portion at the front end of the double-slope pushing seat abuts against the inclined portion at the rear end of the double-slope moving plate, the double-slope pushing seat that continues to move squeezes the corresponding double-slope moving plate, so that the double-slope moving plates on both sides move horizontally away from each other, and the support frame that moves synchronously with the double-slope moving plate gradually compresses the first elastic member. The transmission gear plate that moves synchronously with the double-slope moving plate drives the transmission gear to rotate, and the rotating extrusion lifting shaft drives the two lifting guide frames to move downward synchronously until the inclined portion at the front end of the double-slope pushing seat just separates from the inclined portion at the rear end of the double-slope moving plate. S02. During the sliding process of the double-slanted pushing seat along the double-slanted moving plate, the photovoltaic panel conveying mechanism carrying the photovoltaic panel continues to approach the laminating station, and the glue in the hollow glue coating cylinder gradually flows out along the glue coating groove at the bottom thereof and is coated on the top of the photovoltaic panel. When the rear end of the photovoltaic panel is close to the hollow glue coating cylinder, the glue coating groove at the bottom of the hollow glue coating cylinder is stopped from continuing to discharge glue, and then the photovoltaic panel conveying mechanism carrying the photovoltaic panel is continued to be controlled to move toward the laminating station until the photovoltaic panel conveying mechanism just moves to the laminating station, at which time the double-slanted pushing seat just breaks away from the opposite position. The corresponding double-slope moving plates, under the action of the elastic restoring force of the first elastic member, make the double-slope moving plates on both sides approach each other until the double-slope moving plates on both sides return to their initial positions. At this time, the inclined portions at the front ends of the double-slope moving plates just abut against the inclined portions at the rear ends of the corresponding double-slope pushing seats. During the resetting process of the double-slope moving plates on both sides, the transmission toothed plates that move synchronously with the double-slope moving plates drive the transmission gears to rotate in the opposite direction, and the extrusion lifting shafts that rotate in the opposite direction drive the two lifting guide frames to move upward and reset synchronously. At this time, the hollow glue coating cylinder returns to its initial position. S03. The controller starts the scraping control motor to drive the scraping control screw to rotate, driving the first U-shaped frame and the various components thereon to move horizontally toward the top of the guide rail until the first U-shaped frame and the various components thereon move to the laminating station. At this time, the first glue collection box is attached to the front and back sides of the photovoltaic panel, and the second glue collection box is attached to the left and right sides of the photovoltaic panel. Then, the upper photovoltaic panel is accurately pressed onto the lower photovoltaic panel by the intelligent robotic arm. After the lamination process of the photovoltaic module is completed, the intelligent robotic arm automatically rotates and resets. The scraping control motor drives the scraping control screw to rotate in the opposite direction, driving the first U-shaped frame and the various components on it to move horizontally away from the laminating station until the first U-shaped frame and the various components on it return to their initial positions. In this process, the first scraping member scrapes the overflowed glue at the intersection gaps of the front and rear sides of the photovoltaic module, and the scraped overflowed glue enters the first glue collection box along the inclined glue guide plate and the first glue collection port for collection; Then, the scraping control motor drives the scraping control screw to rotate forward again, so that the first U-shaped frame and the various components on it return to the laminating station again, and the hydraulic cylinder is started to drive the second U-shaped frame to move upward to the designated position. Under the action of the second U-shaped frame, the first glue collection boxes on the front and rear sides move upward, so that the first glue collection boxes on the front and rear sides are misaligned with the photovoltaic module. At this time, the second scraping member is located on the left and right sides of the photovoltaic module, and then continues to control the photovoltaic panel conveying mechanism carrying the photovoltaic module to move forward, and scrapes the overflowed glue into the second glue collection box through the second scraping member for collection; S05. When the laminated photovoltaic module leaves the lamination station and one end of the photovoltaic module rests on the conveyor belt, the negative pressure adsorption of the photovoltaic module is released by the negative pressure generator, and then the photovoltaic module is transported to the back-end process through the operation of the conveyor belt. Then, the scraper control motor drives the scraper control screw to rotate in the opposite direction again, so that the first U-shaped frame and the various components thereon return to the initial position, and then the hydraulic cylinder drives the second U-shaped frame to move downward to complete the reset. Then, the travel control motor controls the travel gear to roll in the opposite direction along the travel gear seat until the unloaded photovoltaic panel conveying mechanism returns to the initial position; S06. During the horizontal movement of the double-slanted moving plates on both sides away from each other, the downward-moving hollow glue coating cylinder drives the opening and closing control gear ring to move downward synchronously. During the downward movement of the opening and closing control gear ring, the cylinder rolls along the L-shaped meshing portion, causing the arc-shaped sealing plate to gradually deviate from the glue coating slot until the hollow glue coating cylinder is close to the photovoltaic panel below it. At this time, the arc-shaped sealing plate releases the blockage of the glue coating slot. Subsequently, while the photovoltaic panel continues to move forward, the glue discharge control motor controls the glue discharge control screw to rotate, causing the two glue pushing pistons inside the hollow glue coating cylinder to approach each other, thereby driving the glue in the hollow glue coating cylinder to gradually flow out along the glue coating slot and coat the top of the photovoltaic panel; S07. When the rear end of the photovoltaic panel is close to the hollow glue coating cylinder, while controlling the two glue pushing pistons to move away from each other and reset, the electromagnet on the fixed connecting plate is energized to generate a magnetic repulsion force on the magnet disk, thereby causing the L-shaped meshing part to move out of the opening and closing control gear ring. At this time, under the action of the arc-shaped elastic member, the arc-shaped sealing plate is rotated in the opposite direction and reset to re-seal the glue coating groove. After the unloaded photovoltaic panel conveying mechanism returns to the initial position, the electromagnet on the fixed connecting plate is controlled to be de-energized and demagnetized to release the magnetic repulsion force on the magnet disk. Under the action of the elastic restoring force of the second elastic member, the L-shaped meshing part is reset and re-engaged with the opening and closing control gear ring. The controller opens the control valve to allow the glue in the glue storage box to flow along the first glue outlet pipe and the second glue outlet pipe into the hollow glue coating cylinder, thereby realizing the replenishment of glue in the hollow glue coating cylinder.
