Abstract
Description
Technical Field
[0001] This invention relates to the field of photovoltaic module lamination technology, and in particular to a continuous lamination device for double-glass photovoltaic modules. Background Technology
[0002] Double-glass photovoltaic (PV) modules are an advanced solar panel design consisting of solar cells sandwiched between two panes of glass. This design significantly enhances the module's mechanical strength, enabling it to withstand external forces such as snow pressure and trampling, while also reducing deformation and microcracks in the solar cells. Furthermore, double-glass PV modules possess bifacial power generation capabilities; incident light energy on the back side is absorbed and converted into electrical energy, increasing the light-receiving area of the cells and thus achieving a higher power generation gain.
[0003] In the manufacturing of double-glass photovoltaic modules, lamination is a crucial step, involving pressing solar cells, encapsulation materials, and two glass panes together to form a complete and durable photovoltaic module. Chinese invention patent CN108437601A discloses a continuous lamination device for bifacial double-glass photovoltaic modules. This device, through a series of automated processes, places the photovoltaic module onto a mounting base. Then, a first drive mechanism drives the transmission rollers of a conveying mechanism, utilizing the drive teeth on the rollers to engage with the drive teeth on the mounting base, moving the mounting base within a conveying channel. When the mounting base reaches below the pressure applying mechanism, a second drive mechanism lowers the pressure applying mechanism, precisely laminating the photovoltaic module.
[0004] However, despite its innovative approach to automated lamination, the equipment has some limitations in practical applications. First, before use, the various material layers of the photovoltaic modules must be manually stacked neatly, a step that cannot be fully automated. Second, after lamination, the photovoltaic modules must be manually removed from the mounting bracket before the next lamination cycle can begin. This manual intervention reduces overall lamination efficiency, especially in high-efficiency assembly line production, where this discontinuous workflow becomes a bottleneck for improving productivity. Summary of the Invention
[0005] In order to overcome the shortcomings of the non-continuous lamination process in the prior art, the present invention provides a continuous lamination device for double-glass photovoltaic modules.
[0006] The technical solution of the present invention is as follows: a continuous lamination device for double-glass photovoltaic modules, comprising a base, a rodless cylinder, and a lamination module. A vertically arranged rodless cylinder is installed in the middle of the base, and a lamination module is fixedly connected to the moving part of the rodless cylinder. A rotating frame is rotatably installed in the middle of the base, surrounding the rodless cylinder. A lamination frame is symmetrically arranged on the upper part of the rotating frame and slides with it. A discharge conveyor and a feeding conveyor are respectively arranged on the left and right sides of the base. The lamination frame has an opening, which connects with the discharge conveyor or the feeding conveyor to realize the transfer of the workpiece. A component for pushing the workpiece out is also provided at the bottom of the lamination frame.
[0007] As a preferred embodiment of the present invention, the feeding and conveying frame is provided with three layers of conveyor belts.
[0008] As a preferred embodiment of the present invention, guide slots are provided on the left and right sides of the rotating frame, and a slider is fixedly provided on the side of the laminating frame near the rodless cylinder. The rotating frame and the laminating frame slide together through the slider and the guide slots.
[0009] As a preferred technical solution of the present invention, the component for pushing out the workpiece consists of a mounting block, a lifting push rod and an elastic element. The mounting block is fixedly set at the bottom of the lamination frame, and the lifting push rod is symmetrically and slidably arranged through the mounting block. The pushing part at the top of the lifting push rod penetrates through the bottom plate of the lamination frame, and an elastic element is provided between the lifting push rod and the mounting block.
[0010] As a preferred embodiment of the present invention, a gear ring is arranged around the lower outer side of the rotating frame, a mounting bracket is fixedly arranged on the upper surface of the base, a servo motor is mounted on the side of the mounting bracket, and a full gear that meshes with the gear ring is fixedly arranged on the output shaft of the servo motor.
[0011] As a preferred embodiment of the present invention, a guide ring frame is also provided in the middle of the base, and a snap-fit guide plate is fixedly provided at the bottom of the laminate frame. The lower part of the snap-fit guide plate is embedded in the annular groove of the guide ring frame, and the snap-fit guide plate can slide in the annular groove of the guide ring frame.
[0012] As a preferred embodiment of the present invention, the guide ring frame is divided into a fixed part and a movable part.
[0013] As a preferred embodiment of the present invention, a hydraulic cylinder is installed on the base directly below the movable part of the guide ring frame. The movable end of the hydraulic cylinder is fixedly connected to the movable part of the guide ring frame. The extension or retraction of the movable end of the hydraulic cylinder will pull the movable part and the snap-fit guide plate located on the movable part and the laminate frame to move up and down synchronously.
[0014] As a preferred technical solution of the present invention, right-angle connecting rods are slidably arranged on both the front and rear sides of the discharge conveyor frame. A wedge block is fixedly connected to the lower part of the two right-angle connecting rods. The top of the wedge block is set as an inclined surface of the discharge conveyor frame. When the wedge block rises, its inclined surface contacts the bottom of the lifting push rod.
[0015] As a preferred technical solution of the present invention, cams are provided at both ends of the right rotating shaft of the discharge conveyor frame. The cams are in contact with the right-angle connecting rod, and the rotation of the cams will lift the right-angle connecting rod and simultaneously raise the wedge block.
[0016] The beneficial effects are as follows: This invention sets the feeding and conveying frame in three layers. The moving part, the clamping guide plate, and the laminating frame are pulled down to the bottom layer by the hydraulic cylinder. Subsequently, the three are pushed upward layer by layer, and the raw material layers are laid in the laminating frame layer by layer through the feeding and conveying frame. The laying and stacking of raw materials can be completed during the upward process, which is efficient and does not require manual assistance. After lamination, the laminating frame is transferred to the discharge conveying frame by the servo motor and the cooperation of the gear and the gear ring. As the discharge conveying frame is running, the tip of the cam will lift the right-angle connecting rod and raise the wedge block. The inclined surface of the wedge block will contact the bottom of the two lifting push rods in turn and lift them up, so that the photovoltaic module in the laminating frame slides into the discharge conveying frame in an inclined position, thereby automatically pushing out the workpiece and improving the continuity of the entire lamination process.

They are only for the convenience of describing this invention 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. Therefore, they should not be construed as limitations on this invention.
[0028] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will now be clearly and completely described in conjunction with the accompanying drawings. It should be understood that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0029] Please see Figure 1 and Figure 2 This invention provides a continuous lamination device for double-glass photovoltaic modules, including a base 1, a rodless cylinder 11, and a lamination module 12. The rodless cylinder 11 is vertically installed in the middle of the base 1, and the lamination module 12 for laminating the double-glass photovoltaic modules is fixedly connected to the movable part of the rodless cylinder 11. When the rodless cylinder 11 is activated, its movable part rises or falls, which drives the lamination module 12 to rise and fall synchronously, thereby adjusting the position of the lamination module 12 and better completing the lamination process of the double-glass photovoltaic modules; see reference. Figure 2 It also includes a rotating frame 13 and a laminating frame 14. The rotating frame 13 is rotatably mounted in the middle of the base 1 and surrounds the rodless cylinder 11. Guide slots 131 are provided on the left and right sides of the rotating frame 13. Two laminating frames 14 are provided, and a slider 141 is fixedly mounted on the side of the two laminating frames 14 that is close to each other by bolts. The slider 141 can slide in the guide slot 131, and through the cooperation of the slider 141 and the guide slot 131, the laminating frame 14 can slide up and down relative to the rotating frame 13; see reference. Figure 1 , Figure 8 and Figure 9The base 1 has a discharge conveyor 42 and a feeding conveyor 41 on its left and right sides, respectively. The feeding conveyor 41 has three layers of conveyor belts: the lower layer conveys the glass base plate and EVA film, the middle layer conveys the battery cells and EVA film, and the upper layer conveys the glass top plate. The lamination frame 14 has an opening. When the opening of the lamination frame 14 is connected to the feeding conveyor 41, the raw material layer can be fed into the lamination frame 14 layer by layer. Subsequently, it is laminated by the lamination module 12. When the opening of the lamination frame 14 is connected to the discharge conveyor 42, the laminated photovoltaic module inside can be output to the discharge conveyor 42 and conveyed outward.
[0030] Please see Figure 4 , Figure 5 and Figure 6 A guide ring frame 31 is also provided in the middle of the base 1. The guide ring frame 31 is divided into a fixed part 311 and a movable part 312. A hydraulic cylinder 33 is installed on the base 1 directly below the movable part 312. The movable end of the hydraulic cylinder 33 is fixedly connected to the movable part 312 of the guide ring frame 31. Initially, the fixed part 311 and the movable part 312 form a complete ring. A snap-fit guide plate 32 is fixedly provided at the bottom of the lamination frame 14. The lower part of the snap-fit guide plate 32 is embedded in the annular groove of the guide ring frame 31, and the snap-fit guide plate 32 can slide in the annular groove of the guide ring frame 31. The hydraulic cylinder 33 can lower the movable part 312. When the movable part 312 lowers, the snap-fit guide plate 32 on the movable part 312 and the lamination frame 14 will lower synchronously and pass through the notch of the fixed part 311.
[0031] The hydraulic cylinder 33 drives the movable part 312 and the snap-in guide plate 32 on the movable part 312 to descend and the laminating frame 14, so that the opening of the laminating frame 14 connects with the lower conveyor belt of the feeding and transfer frame 41, so that the glass base plate and EVA film can be fed into the laminating frame 14. Then, the laminating frame 14 is driven to rise layer by layer, so that the battery cell, EVA film and glass top plate are fed into the laminating frame 14 in sequence, completing the stacking of raw material layers. Subsequently, the rodless cylinder 11 is activated to lower the laminating module 12 and perform lamination processing on the raw materials stacked in the laminating frame 14.
[0032] Please see Figure 2A gear ring 24 is arranged around the lower outer side of the rotating frame 13. A mounting frame 21 is fixedly installed on the upper surface of the base 1. A servo motor 22 is installed on the side of the mounting frame 21. A full gear 23 that meshes with the gear ring 24 is fixedly installed on the output shaft of the servo motor 22. After the raw material in the lamination frame 14 on the right is laminated, the servo motor 22 is started to drive the full gear 23 to rotate. Under the meshing action of the full gear 23 and the gear ring 24, the gear ring 24 will rotate with the rotating frame 13. The two lamination frames 14 can also rotate along the annular groove of the guide ring frame 31 through the snap-in guide plate 32 until the two positions are interchanged. The empty lamination frame 14 is connected to the feeding transmission frame 41, and the lamination frame 14 with photovoltaic modules is connected to the discharge transmission frame 42.
[0033] Please see Figure 7 and Figure 9 Both lamination frames 14 have components at their bottoms for ejecting workpieces. These components consist of a mounting block 51, a lifting push rod 52, and an elastic element 53. The mounting block 51 is bolted to the bottom of the lamination frame 14. Two through holes are symmetrically provided on the mounting block 51 for the rod-shaped portion of the lifting push rod 52 to pass through. The rod-shaped portion of the lifting push rod 52 passes through the through holes and slides into the mounting block 51. An elastic element 53, which is a spring, is provided between the rod-shaped portion of the lifting push rod 52 and the mounting block 51. The top of the lifting push rod 52 is a circular plate-shaped pushing portion that penetrates the bottom plate of the lamination frame 14. Right-angle connecting rods 61 are slidably mounted on both the front and rear sides of the discharge conveyor frame 42. A wedge-shaped block 62 is fixedly connected to the lower part of both right-angle connecting rods 61. Cams 63 are provided at both ends of the right-hand rotating shaft of 2. Cams 63 contact the right-angle connecting rod 61 on the same side. When the discharge conveyor 42 is running, cams 63 will rotate synchronously with the right-hand rotating shaft of the discharge conveyor 42. The tip of cam 63 will then lift the right-angle connecting rod 61 and simultaneously lift the wedge block 62. The top of the wedge block 62 is set as an inclined surface sloping to the lower left. Initially, the highest point of the inclined surface contacts the bottom of the lifting push rod 52 on the right side of the lamination frame 14. When the wedge block 62 rises, it will first lift the lifting push rod 52 on the right side. When the inclined surface contacts another lifting push rod 52, the two lifting push rods 52 work together to lift the photovoltaic module in the lamination frame 14. At this time, the photovoltaic module is tilted and will slide into the discharge conveyor 42, and finally be output by the discharge conveyor 42.
[0034] Obviously, the embodiments described above are only some embodiments of the present invention, and not all embodiments. They only express the preferred implementation of the present invention and are described in a relatively specific and detailed manner, but should not be construed as limiting the scope of the present invention.
[0035] It should be noted that, for those skilled in the art, various modifications, additions or subtractions, improvements and substitutions can be made without departing from the concept of the present invention. Therefore, based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
