Description

Technical Field

[0001] The present invention relates to the technical field of film laminating, and particularly to a precise film laminating device for perovskite photovoltaic modules. Background Art

[0002] Film laminating refers to adding a layer of film on the surface of a material to protect the material from the external environment and enhance its physical and chemical properties. A perovskite photovoltaic module refers to a photovoltaic power generation technology based on perovskite-structured materials. Perovskite materials are usually composed of organic and inorganic components, having excellent light absorption performance and low production costs. Perovskite photovoltaic modules have potential advantages in terms of photoelectric conversion efficiency and production convenience. During the production and processing process, perovskite photovoltaic modules usually need to be film-laminated and encapsulated, and film laminating can effectively prevent the deterioration of perovskite materials caused by environmental factors.

[0003] In the prior art, when laminating a perovskite photovoltaic module, a film roll is unwound by an unwinding device, and under the conveyance of a conveying device, the film covers the photovoltaic module to complete film laminating. During the film laminating process, when there is air flow interference in the environment, the air flow will bring air into the gap between the film and the photovoltaic module, resulting in the formation of some bubbles between the film and the photovoltaic module, affecting the film laminating effect. Subsequently, when the photovoltaic module is in use, the presence of bubbles will also cause light to scatter and refract between the film and the module, resulting in part of the light being unable to effectively reach the photoelectric conversion layer of the photovoltaic module, thereby reducing the photoelectric conversion efficiency of the photovoltaic module and reducing the power generation, which is not conducive to the normal operation of the photovoltaic module.

[0004] Therefore, we propose a precise film laminating device for perovskite photovoltaic modules to solve the problems raised in the above background art. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the present invention is in use, when the camera detects bubbles between the film and the photovoltaic module, the PLC controller controls the four pneumatic grippers to start, and clamps the film on both sides of the photovoltaic module. Then the control line rail starts, driving the moving block, the hydraulic rod, the fixed frame and the adjusting seat to move backward, driving the inclined scraping bar and the arc scraping bar to move backward. The arc scraping bar pushes the bubbles in the middle backward, and the bubbles are pushed to the two inclined scraping bars. The arc scraping bar can make up for the leakage at the sharp corners of the two inclined scraping bars and play a supplementary role. At the same time, the two inclined scraping bars push the bubbles on both sides backward and generate a component force along the inclined direction on the bubbles, which helps to push the bubbles to the edge and thus discharge them more thoroughly. With the cooperation of the arc scraping bar and the inclined scraping bar, it is beneficial to comprehensively discharge the bubbles, reduce the bubble residue, avoid affecting the film covering effect and the subsequent normal operation of the perovskite photovoltaic module.

[0017] 2. When the present invention is in use, start the servo motor and the electrostatic generator. The servo motor drives the rotating rod and the power roller to rotate together. At the same time, the conveyor works to convey the photovoltaic module. After the electrostatic generator starts, it generates static electricity and applies the static electricity to the surface of the film below. Under the action of the power roller and the conveyor, the photovoltaic module moves to the left and covers the film with static electricity on the surface of the photovoltaic module. During film covering, the power roller will apply pressure to both the film and the photovoltaic module at the same time to make them fit tightly, realizing electrostatic film covering. Electrostatic film covering can make the film fit more tightly on the surface of the photovoltaic module, improving the sealing performance and stability of the package. The photovoltaic module is positioned by two groups of positioning wheels to prevent deviation during transportation and facilitate subsequent precise film covering. After the bubbles are discharged, start the pneumatic gripper to release the clamping of the film. Then the conveyor and the servo motor resume work, and continue to convey the film-covered photovoltaic module to the lower part of the cutting machine for cutting.

[0018] 3. When the present invention is in use, start the forward and reverse motor to drive the rotation of the rotating shaft and the adjusting gear. Drive the reinforcing strip and the moving seat to move forward through the two racks, then drive one end of the two movable connecting rods to move backward. At the same time, the other ends of the two movable connecting rods rotate in the corresponding connecting seats and generate a pulling force on the two connecting seats, so that the two inclined scraping strips both rotate and close with the limiting rod as the center, and the distance becomes smaller, which is convenient for adapting to photovoltaic modules of different widths. When the rotation angles of the two inclined scraping strips meet the requirements, turn off the forward and reverse motor, so as to achieve the effect of adjusting the opening and closing angles of the two inclined scraping strips.

[0023] In this embodiment, during use, the conveyor 102, servo motor 107, electrostatic generator 110, camera 203, hydraulic rod 205, forward and reverse motor 222, cutting machine 3, pneumatic gripper 4 and PLC controller 202 are electrically connected. When the photovoltaic module is electrostatically laminated by the laminating module 1 and conveyed to the lower part of the bubble removal module 2, the conveyor 102 automatically pauses for a while. When the photovoltaic module is being conveyed and passes by the camera 203, the camera 203 takes pictures of the film on the surface of the photovoltaic module, and conveys the captured image information to the PLC controller 202 in the form of electrical signals for analysis and recognition. When bubbles are detected between the film and the photovoltaic module, when the photovoltaic module moves below the linear rail 204 and the conveyor 102 pauses, the PLC controller 202 will control the four pneumatic grippers 4 to start and clamp the film on both sides of the photovoltaic module, as Figure 4As shown, the film is always kept flat, which is convenient for better discharging bubbles subsequently. Then, the control rail 204 is started to drive the moving block 5, the hydraulic rod 205 and the support telescopic rod 227 to move. The adjusting seat 207 is driven to move backward through the fixing frame 206, further driving the two inclined scraping strips 209 and the arc-shaped scraping strip 212 to move backward. At this time, the bottom of the arc-shaped scraping strip 212 first contacts the film on the surface of the photovoltaic module and generates a thrust on the bubbles. Then, the two inclined scraping strips 209 gradually contact the film surface. With the drive of the rail 204, the arc-shaped scraping strip 212 and the inclined scraping strips 209 will move backward on the film surface. During this process, the arc-shaped scraping strip 212 will push the bubbles existing in the middle backward, and the bubbles will be pushed along the arc surface of the arc-shaped scraping strip 212 to the two inclined scraping strips 209. The arc-shaped scraping strip 212 can make up for the leakage at the sharp corners of the two inclined scraping strips 209 and play a supplementary role to avoid the omission of bubbles in the middle part, which affects the bubble discharging effect. At the same time, the two inclined scraping strips 209 push the bubbles on both sides backward and generate a component force along the inclined direction on the bubbles. This component force helps to push the bubbles to the edge, so as to discharge them more thoroughly. With the cooperation of the arc-shaped scraping strip 212 and the inclined scraping strips 209, it is beneficial to comprehensively discharge the bubbles, reduce the bubble residue, avoid affecting the film covering effect and the subsequent normal operation of the perovskite photovoltaic module, and solve the problem that when there is air flow interference in the environment during the film covering process of the perovskite photovoltaic module, air will be brought into the gap between the film and the photovoltaic module to form bubbles, which affects the film covering effect and also affects the normal operation of the perovskite photovoltaic module. When the moving block 5 moves to the rear, the inclined scraping strips 209 and the arc-shaped scraping strip 212 leave from the top of the film. Then, the hydraulic rod 205 is started to pull the adjusting seat 207 to move upward through the fixing frame 206, so that the inclined scraping strips 209 and the arc-shaped scraping strip 212 leave from the top of the film. Then, the rail 204 drives the moving block 5 and the adjusting seat 207 to move in the reverse direction to reset, and at the same time, the conveyor 102 resumes working and continues to convey the photovoltaic module to the cutting machine 3. After the adjusting seat 207 is reset, the hydraulic rod 205 is started again to push the adjusting seat 207 to move downward to restore the original state, which is convenient for performing the bubble discharging operation on the next photovoltaic module.

[0024] Embodiment 2: As Figures 1 - 6As shown in the figure, the film laminating assembly 1 includes a frame 101. Inside the frame 101 is arranged a conveyor 102. Positioning rails 103 are arranged on both the front surface and the rear surface of the conveyor 102. A plurality of positioning wheels 104 are arranged inside both of the two positioning rails 103. Four reinforcing and adjusting rods 105 are fixedly installed on the outer surface of one side of both of the two positioning rails 103. A film laminating frame 106 is installed on the top of the frame 101 by bolts. A cutting machine 3 is arranged on the top of the frame 101. A servo motor 107 is installed on the rear surface of the frame 101 through an auxiliary plate. A rotating rod 108 is fixedly installed at the output end of the servo motor 107. A driving roller 109 is fixedly installed on the outer surface of the rotating rod 108. An electrostatic generator 110 is installed on the top surface inside the film laminating frame 106 by bolts. A connecting rod 111 is installed inside the film laminating frame 106 by bolts. A guiding roller 112 is movably sleeved on the outer surface of the connecting rod 111. Every four horizontally distributed reinforcing and adjusting rods 105 among the eight reinforcing and adjusting rods 105 are taken as a group. One ends of the two groups of reinforcing and adjusting rods 105 respectively penetrate through the front surface and the rear surface of the frame 101 movably.

[0025] In this embodiment, during use, the photovoltaic module is placed on the conveyor 102 for conveying, and the conveyor 102 conveys intermittently. The film roll is unrolled by an uncoiler. One end of the film roll passes through the bottom of the guiding roller 112, then passes through the electrostatic generator 110, and passes under the driving roller 109, covering the photovoltaic module. The height of the guiding roller 112 is slightly higher than that of the driving roller 109. The film at the bottom of the guiding roller 112 does not contact the photovoltaic module. The top of the film at the driving roller 109 contacts the driving roller 109, and the bottom contacts the module, as Figure 4As shown in the figure. Start the servo motor 107 and the electrostatic generator 110. The servo motor 107 drives the rotating rod 108 and the power roller 109 to rotate together. At the same time, the conveyor 102 works to convey the photovoltaic module. After the electrostatic generator 110 is started, static electricity is generated and applied to the surface of the film below. Under the action of the power roller 109 and the conveyor 102, the photovoltaic module moves to the left, and the film with static electricity is covered on the surface of the photovoltaic module. During film covering, the power roller 109 will apply pressure to both the film and the photovoltaic module at the same time, so that the two are closely attached to achieve electrostatic film covering. Electrostatic film covering can make the film more closely attached to the surface of the photovoltaic module, improve the sealing and stability of the package, and reduce the possibility of the film separating from the module due to external forces and other factors. A set of positioning wheels 104 are arranged on both the front and rear of the conveyor 102. When the photovoltaic module 2 is placed on the conveyor 102, its front and back surfaces are respectively in contact with the two sets of positioning wheels 104, and the photovoltaic module is positioned through the two sets of positioning wheels 104 to prevent deviation during transportation and facilitate subsequent accurate film covering. By unscrewing the bolts connecting the reinforcement adjusting rod 105 and the frame 101, the positioning rail 103 can be moved, so as to adjust the positions of the two positioning rails 103 to adapt to photovoltaic modules of different sizes. When the photovoltaic module under the power roller 109 completes electrostatic film covering and moves to the lower part of the bubble removal assembly 2, the conveyor 102 and the servo motor 107 will pause for a while. During this process, the pneumatic gripper 4 clamps the film on the side of the photovoltaic module, and the bubble removal assembly 2 detects and discharges the bubbles, and then the pneumatic gripper 4 is started to release the clamping of the film. Then the conveyor 102 and the servo motor 107 resume work and continue to convey the film-covered photovoltaic module to the lower part of the cutting machine 3. At this time, the conveyor 102 and the servo motor 107 pause again, and the cutting machine 3 is started to cut the film on the surface of the photovoltaic module.

When the moving seat 215 moves backward, it will drive one end of the two movably connected movable link rods 214 to move backward, making the angle between the two movable link rods 214 gradually smaller. At the same time, the other ends of the two movable link rods 214 rotate in the corresponding connecting seats 213 and generate a pulling force on the two connecting seats 213, causing the two inclined scraping strips 209 to rotate and close with the limiting rod 208 as the center. At this time, the angle between the two inclined scraping strips 209 gradually becomes smaller. When the rotation angle of the two inclined scraping strips 209 meets the requirements, the forward and reverse motor 223 is turned off, thus achieving the effect of adjusting the opening and closing angle of the two inclined scraping strips 209. When the angle between the two inclined scraping strips 209 becomes smaller, one end of the two inclined scraping strips 209 will move towards the middle, that is, the distance between the two inclined scraping strips 209 becomes smaller, facilitating adaptation to photovoltaic modules of different widths and better discharging air bubbles. By pulling out the clamping block 211, the arc-shaped scraping strip 212 can be removed from the sharp corners of the two inclined scraping strips 209, facilitating the replacement of arc-shaped scraping strips 212 of different sizes to adapt to the inclined scraping strips 209 after the angle adjustment.

[0028] The effects achieved by the entire mechanism and its working principle are as follows: The film roll is unwound by an unwinder. One end of the film roll passes through the bottom of the guiding roller 112, then passes through the electrostatic generator 110, and passes under the driving roller 109, covering the photovoltaic module. The servo motor 107 and the electrostatic generator 110 are started. The servo motor 107 drives the rotating rod 108 and the driving roller 109 to rotate together. At the same time, the conveyor 102 operates to convey the photovoltaic module. The electrostatic generator 110 generates static electricity and applies the static electricity to the film surface below. Under the action of the driving roller 109 and the conveyor 102, the photovoltaic module moves to the left, and the film with static electricity is covered on the surface of the photovoltaic module. During film covering, the driving roller 109 applies pressure to both the film and the photovoltaic module simultaneously, making the two fit tightly, achieving electrostatic film covering. When the photovoltaic module 2 is placed on the conveyor 102, its front and back surfaces are respectively in contact with two groups of positioning wheels 104, and the photovoltaic module is positioned by the two groups of positioning wheels 104. When the photovoltaic module is conveyed under the bubble removal assembly 2, the conveyor 102 automatically pauses for a while. The film on the surface of the photovoltaic module is photographed by the camera 203, and the photographed image information is transmitted to the PLC controller 202 in the form of an electrical signal for analysis and recognition. When bubbles appear between the film and the photovoltaic module, when the photovoltaic module moves below the linear rail 204 and the conveyor 102 pauses, the PLC controller 202 controls the four pneumatic grippers 4 to start, clamping the film on both sides of the photovoltaic module, so that the film always remains flat. Then, the linear rail 204 is controlled to start, driving the moving block 5, the hydraulic rod 205 and the support telescopic rod 227 to move. The adjusting seat 207 is driven to move backward through the fixing frame 206, further driving the two inclined scraping bars 209 and the arc-shaped scraping bar 212 to move backward. At this time, the bottom of the arc-shaped scraping bar 212 first contacts the film on the surface of the photovoltaic module and generates a thrust on the bubbles. Then, the two inclined scraping bars 209 gradually contact the film surface. With the driving of the linear rail 204, the arc-shaped scraping bar 212 and the inclined scraping bars 209 will move backward on the film surface. During this process, the arc-shaped scraping bar 212 will push the bubbles existing in the middle backward, and the bubbles will be pushed along the arc surface of the arc-shaped scraping bar 212 to the two inclined scraping bars 209. The arc-shaped scraping bar 212 can make up for the leakage at the sharp corners of the two inclined scraping bars 209 and play a supplementary role. At the same time, the two inclined scraping bars 209 push the bubbles on both sides backward and generate a component force along the inclined direction on the bubbles. This component force helps to push the bubbles to the edge, so as to discharge them more thoroughly. With the cooperation of the arc-shaped scraping bar 212 and the inclined scraping bars 209, it is beneficial to comprehensively discharge the bubbles, reduce bubble residues, and avoid affecting the film covering effect and the subsequent normal operation of the perovskite photovoltaic module.When the moving block 5 moves to the rear, the inclined scraping strip 209 and the arc-shaped scraping strip 212 leave from the top of the film. Then, the hydraulic rod 205 is activated, and the adjusting seat 207 is pulled upward through the fixing frame 206, causing the inclined scraping strip 209 and the arc-shaped scraping strip 212 to leave from the top of the film. Then, the wire rail 204 drives the moving block 5 and the adjusting seat 207 to move in the reverse direction to reset. At the same time, the conveyor 102 resumes operation and continues to convey the photovoltaic module to the cutting machine 3. After the adjusting seat 207 is reset, the hydraulic rod 205 is activated again to push the adjusting seat 207 downward to restore the original state, facilitating the air bubble discharging operation for the next photovoltaic module. The forward and reverse motor 222 is started to drive the rotating shaft 223 and the adjusting gear 224 to rotate, driving the two rack bars 217 to move forward on the outer surfaces of the corresponding reinforcing rods 218 respectively, and driving the reinforcing strip 216 and the moving seat 215 to move forward. At the same time, the two sliders 219 slide in the corresponding slide rails 220. When the moving seat 215 moves backward, it drives one end of the two movably connected movable link rods 214 to move backward, causing the included angle between the two movable link rods 214 to gradually become smaller. At the same time, the other ends of the two movable link rods 214 rotate in the corresponding connecting seats 213 and generate a pulling force on the two connecting seats 213, causing the two inclined scraping strips 209 to rotate and close with the limiting rod 208 as the center. When the rotation angles of the two inclined scraping strips 209 meet the requirements, the forward and reverse motor 223 is turned off, thus achieving the effect of adjusting the opening and closing angles of the two inclined scraping strips 209 to facilitate adapting to photovoltaic modules of different widths. By pulling out the clamping block 211, the arc-shaped scraping strip 212 can be removed from the sharp corners of the two inclined scraping strips 209, facilitating the replacement of arc-shaped scraping strips 212 of different sizes to adapt to the inclined scraping strips 209 after the angle adjustment.
