Description

[0002] Solar energy devices rely on photovoltaic panels to absorb solar energy and convert it into electrical energy based on the photovoltaic effect. When sunlight shines on the surface of a photovoltaic panel, photons are absorbed by silicon atoms and other semiconductor materials, thus gaining energy.

[0003] Photovoltaic panels, used to absorb solar energy, are composed of multiple small solar cells. These cells are stacked and connected by conductive materials to form the basic structure of a photovoltaic panel. The stacked solar cells need to be encapsulated by a glass panel to protect the panel and its internal circuitry.

[0004] Before welding, these solar cells, used to absorb solar energy, must be precisely matched to the glass panel, and the relative positions of the cells and the glass panel must remain unchanged during the stacking process to guarantee the electrical performance and mechanical stability of the final product. In the current manufacturing process, the cells are placed directly on the glass panel for welding. This method presents several challenges: because the glass panel bears the welding pressure from the bottom, its strength limits the amount of force that can be applied, which affects the weld quality.

[0025] The present application will now be described in detail with reference to the accompanying drawings.

[0026] In the manufacturing process of photovoltaic (PV) modules, conductive metal electrodes are coated onto the positive and negative electrodes of the PV cells. Under sunlight, these cells convert light energy into electrical energy. The shingling process uses heat and pressure to firmly bond electrodes of different materials to the PV cells, thereby forming a complete solar cell module.

[0027] The formed solar panels then need to be encapsulated with glass panels. This encapsulation not only protects the photovoltaic cells from external environmental factors such as moisture, dust, and other physical damage, thus extending their lifespan, but also ensures the panel's high light transmittance, allowing the photovoltaic cells to absorb sunlight to the maximum extent. To improve the power generation efficiency of the panel, multiple photovoltaic cells need to be connected in series to form a large cell string. Before welding, these cells must be precisely matched with the glass panel, ensuring that the relative position of the cells and the glass panel does not change during the stacking process, to guarantee the electrical performance and mechanical stability of the final product.

[0028] In the current manufacturing process, solar cells are directly placed on a glass panel for welding. This method presents several challenges: because the glass panel bears the welding pressure from the bottom, its strength limits the amount of force that can be applied, affecting the weld quality. Furthermore, the obstruction of the glass panel prevents the stacked ends of the solar cells from being placed on the welding platform, forcing multiple welding steps to be performed on different welding points of the solar cells. This not only increases welding time but may also affect the reliability of the welds due to insufficient pressure.

[0029] Therefore, after matching the solar cells with the glass panel, it is necessary to separate each solar cell from the glass panel, stack and solder the individual solar cells, and then re-encapsulate them with the glass panel. How to separate each solar cell from the glass panel while maintaining the proper orientation of the solar cells becomes a major challenge.

[0030] In view of this, embodiments of this application provide a photovoltaic panel feeding mechanism to solve the above problems.

[0031] First Implementation Method

[0032] refer to Figure 1 , Figure 2 The first embodiment of this application provides a photovoltaic panel feeding mechanism, including: a support tray 3, a separation device 1, and a transport device 2. The support tray 3 holds the glass panel of the photovoltaic panel and multiple solar cells. The separation device 1 is disposed above the support tray 3 and is used to adsorb the multiple solar cells placed on the glass panel. The transport device 2 is connected to both the support tray 3 and the separation device 1, and is used to drive the support tray 3 and the separation device 1 to move. The transport device 2 can drive the support tray 3 and the separation device 1 closer together, so that the separation device 1 adsorbs the multiple solar cells placed on the glass panel. After the separation device 1 completes adsorption, the transport device 2 can drive the support tray 3 and the separation device 1 further apart, so that the solar cells are separated from the glass panel.

[0033] During the photovoltaic panel cell welding process, the transport device 2 drives the separation device 1, gradually bringing it closer to the tray carrying the photovoltaic panels until the separation device 1 can precisely contact the cells on the photovoltaic panel. The separation device 1, through its powerful adsorption function, adsorbs all the cells one by one, ensuring that the cells only maintain slight contact with the glass panel of the photovoltaic panel, forming a virtual contact. After adsorption is complete, driven by the transport device 2, the adsorbed cells move in tandem with the separation device 1, ultimately achieving complete separation from the glass panel. Separation between the cells and the glass panel can be achieved simply by the rising and falling of the carrying tray 3 or the separation device 1, reducing the stroke of other equipment movements and accelerating the cell separation speed.

[0034] After separation, the solar cells are efficiently transported to the stacking welding machine for series welding. Due to the absence of a glass panel on the bottom of the cells, they can be placed directly and stably on the welding machine's worktable. Both ends of the cells can directly and tightly contact the welding table, achieving efficient compression connection of the cell circuitry and busbars. Furthermore, since each cell has been positioned and its orientation corrected before reaching the welding machine, there is no need for repositioning upon entering the machine, reducing the time the cells spend inside and accelerating the welding process. Simultaneously, high-frequency welding technology is used to perform simultaneous welding of multiple points, greatly improving welding efficiency. Moreover, unaffected by the glass panel, the external force compression welding method significantly enhances the mechanical strength and electrical connection performance of the weld points, thereby greatly improving the quality and reliability of the welded solar cells.

[0035] To further refer to Figure 1 , Figure 3As shown, the transport device 2 includes a carrier tray transport assembly 2121 and a separation device transport assembly 22. The carrier tray transport assembly 2121 is detachably connected to the carrier tray 3, and the carrier tray transport assembly 2121 drives the carrier tray 3 to move. The separation device transport assembly 22 is connected to the separation device 1, and the separation device transport assembly 22 drives the separation device 1 to move. The motion trajectories formed by the carrier tray transport assembly 2121 and the separation device transport assembly 22 intersect each other.

[0036] The carrier tray transport assembly 2121 and the separation device transport assembly 22 are responsible for driving the movement of the carrier tray 3 and the separation device 1, respectively. After the photovoltaic cells are separated from the glass panel, the carrier tray 3 needs to carry the remaining glass panel and move it to the exit position, waiting for the laminated cells to be reassembled onto the glass panel. During this process, the carrier tray 3 will detach from the photovoltaic panel feeding mechanism. Therefore, the carrier tray 3 and the transport assembly need to be designed as a detachable connection to facilitate the flexible transfer of the carrier tray 3 between different processes. In addition, the movement trajectories of the carrier tray transport assembly 2121 and the separation device transport assembly 22 can be designed to be staggered to ensure that at the intersection point, the separation device 1 can accurately adsorb the cells on the photovoltaic panel, achieving efficient separation operation.

[0037] Second Implementation Method

[0038] In the first embodiment, the separation device 1 can separate the solar cells from the glass panel, allowing the cells to be stacked after separation, thereby increasing the efficiency of the stacking process and the quality of the resulting sheet. However, the mechanical movement of the device introduces some errors, and when the carrier tray transport assembly 2121 and the separation device transport assembly 22 work together, the combined operation of the two sets of devices further amplifies the errors.

[0039] In view of this, refer to Figure 1 , Figure 2 The improvement of the second embodiment of this application compared to the first embodiment is that the carrier pallet transport assembly 2121 includes: a first conveying assembly 211 and a second conveying assembly 212. The first conveying assembly 211 is detachably connected to the carrier pallet 3 and drives the carrier pallet 3 to move vertically. The second conveying assembly 212 is detachably connected to the carrier pallet 3 and drives the carrier pallet 3 to move horizontally.

[0040] The first conveying component 211, through its drive mechanism, can drive the carrier plate 3 to move vertically up and down. The separation device 1 is positioned directly above the carrier plate 3 to directly contact the solar cells. During operation, the first conveying component 211 drives the carrier plate 3 upward until it fully contacts the separation device 1. Once the separation device 1 successfully holds all the solar cells in the carrier plate 3, the first conveying component 211 begins to descend, gradually separating the solar cells from the glass panel. After the carrier plate 3 is driven back to its initial position by the first conveying component 211, the second conveying component 212 takes over the subsequent transfer task. The second conveying component 212 drives the carrier plate 3 to move horizontally, smoothly detaching it from the photovoltaic panel feeding mechanism, and then transports the carrier plate 3 to the next target station to continue the photovoltaic panel assembly and manufacturing process. By driving the carrier plate 3 up and down through the first conveying component 211, the separation between the solar cells and the glass panel can be easily achieved, simplifying the mechanical movement and steps, reducing errors in the separation process, and improving the separation efficiency of the solar cells.

[0041] Specifically, the first conveying component 211 includes a lifting track and a sliding part. The lifting track is arranged vertically, and the sliding part is disposed within the lifting track and slides along the direction of the lifting track. The carrying tray 3 is placed on the sliding part and moves up and down vertically along with the sliding part.

[0042] The sliding part moves along a preset lifting track, achieving a stable trajectory under its guidance. Since the carrier plate 3 always moves synchronously with the sliding part, it also maintains a stable and precise movement path. This design effectively reduces potential misalignment or vibration between the carrier plate 3 and the separation device 1 as they approach each other. When the separation device 1 contacts the battery cells on the carrier plate 3, it accurately captures the cells, thus achieving smooth separation of the cells from the glass panel. The sliding part is driven by a pulley, enabling smooth lifting and lowering along the lifting track. The pulley design effectively reduces vibrations that may occur during the sliding part's movement, ensuring smooth operation and efficient completion of the entire stroke of the battery cell separation process by moving the carrier plate 3 up and down. This not only avoids vibration of the battery cells on the carrier plate 3 but also prevents unexpected changes in the battery cell's posture, thus ensuring the precise adsorption and separation of the battery cells by the separation device 1.

[0043] Furthermore, the second conveying component 212 includes: multiple conveyor belts evenly spaced, and a carrier plate 3 that can be placed on the conveyor belts and move horizontally along with the conveyor belts.

[0044] After the solar cells are separated from the glass panel, the glass panel needs to be transported to the next station to await the completion of the laminated solar cells and their encapsulation. Multiple conveyor belts enable the carrier tray 3 to move horizontally, and the conveyor belts operate smoothly. When multiple conveyor belts work synchronously, they can simultaneously act on the bottom of the carrier tray 3. This ensures that the carrier tray 3 moves smoothly and at a constant speed, avoiding vibration during transportation. In addition, the conveyor belt design allows the carrier tray 3 to move without additional fixing. This feature effectively avoids vibration problems that may occur during the docking of the conveyor belt and the carrier tray 3, thus ensuring that the glass panel is always stored at a consistent angle on the carrier tray 3.

[0045] Third Implementation Method

[0046] In the second embodiment, the cooperation between the first conveying component 211 and the second conveying component 212 of the carrier tray transport assembly 2121 enables the solar cells to be smoothly separated from the glass panel. However, vibrations are inevitable during the process of placing the photovoltaic panel onto the carrier tray 3, affecting the position of the stored solar cells. Therefore, during the adsorption of solar cells, it is necessary to ensure that the position of the separation device 1 matches that of the solar cells to eliminate errors generated during placement or movement.

[0047] In view of this, refer to Figure 1 , Figure 3 The improvement of the third embodiment of this application compared to the second embodiment is that the separation device transport assembly 22 includes: a first slide rail 221, a first slider 222, a second slide rail 223, a second slider 224, and a fixing frame. The first slider 222 is disposed on the first slide rail 221 and moves along the first slide rail 221. The second slide rail 223 is connected to the first slider 222 and can follow the movement of the first slider 222. The first slide rail 221 and the second slide rail 223 are arranged perpendicularly to each other. The second slider 224 is disposed on the second slide rail 223 and moves along the second slide rail 223. The fixing frame is connected to the second slider 224 and can follow the movement of the second slider 224. The separation device 1 is disposed on the fixing frame.

[0048] Through the combination of the first slide rail 221 and the first slider 222, and the coordinated arrangement of the second slide rail 223 and the second slider 224, the mounting frame possesses the ability to move in both the horizontal and vertical directions. This design allows the mounting frame to be flexibly adjusted for battery cells in different positions, thereby improving the adaptability and accuracy of the separation device 1. Since the second slide rail 223 is fixed on the first slider 222, the second slide rail 223 can move synchronously with the movement of the first slide rail 221, realizing the linkage movement in both the horizontal and vertical directions. When the horizontal movement and the vertical movement are combined, the mounting frame fixed on the second slider 224 can move along an arc trajectory. This design allows the separation device 1 mounted on the mounting frame to obtain more diverse movement modes, thereby better adapting to battery cells in different positions and ensuring accurate separation.

[0049] Furthermore, the separation device transport assembly 22 also includes a first lead screw mechanism and a second lead screw mechanism. The first lead screw mechanism is disposed at the end of the first slide rail 221, and the first slider 222 is disposed on the first moving part of the first lead screw mechanism and moves with the first moving part. The second lead screw mechanism is disposed at the end of the second slide rail 223, and the second slider 224 is disposed on the second moving part of the second lead screw mechanism and moves with the second moving part.

[0050] Precise control is required during the adsorption of solar cells by the separation device 1 to avoid adsorption failure due to movement errors or damage to the solar cells due to excessive errors. Therefore, the drive system of the separation device 1 requires extremely high precision. The coordinated operation of the first and second lead screw mechanisms precisely controls the movement of the first slider 222 and the second slider 224, thereby improving the movement accuracy of the fixing frame. This not only ensures the accuracy of the separation device 1 in adsorbing solar cells but also prevents damage to the solar cells due to errors, effectively protecting the safety of the solar cells.

[0051] refer to Figure 1 , Figure 2 , Figure 3 As shown, the separation device 1 includes a suspension frame 11 and multiple adsorption components 12. The suspension frame 11 is connected to a fixed frame. The multiple adsorption components 12 are evenly distributed on the suspension frame 11, and the multiple adsorption components 12 pick up the battery cells from the glass panel, so that the battery cells are in a loose contact with the glass panel.

[0052] In the manufacturing process of photovoltaic panels, multiple solar cells need to be connected in series to form a complete circuit. Therefore, when separating the solar cells from the glass panel, multiple solar cells must be adsorbed simultaneously to ensure that their orientation remains consistent throughout the process, avoiding any impact on subsequent series connection steps due to orientation changes. By designing multiple adsorption components 12, each capable of adapting to different solar cells, the system can comprehensively adsorb all solar cells when multiple adsorption components 12 operate simultaneously. The coordinated movement of the adsorption components 12 achieves the separation of the solar cells from the glass panel. This design ensures that multiple solar cells maintain synchronous movement during separation, preventing orientation changes.

[0053] In addition, the adsorption assembly 12 includes a cylinder and a plurality of adsorption heads 121. The adsorption heads 121 are circular and connected to the cylinder. The cylinder provides negative pressure to the plurality of adsorption heads 121 so that the adsorption heads 121 adsorb the battery cells.

[0054] The cylinder provides stable suction, driving the adsorption head 121 to firmly adsorb the battery cells. Specifically, the cylinder adsorption technology enables rapid and efficient material gripping and placement. This design not only improves operational efficiency but also simplifies the equipment structure to some extent. The cylinder-driven adsorption head 121 achieves high-precision positioning, ensuring that the adsorbed battery cells remain accurately aligned during adsorption and separation. By reducing the swaying of the battery cells, errors in the separation process are effectively reduced, improving operational reliability and accuracy.

[0055] Furthermore, the separation device 1 also includes multiple rotating components. These rotating components are mounted on the suspension frame 11, and each rotating component corresponds one-to-one with the adsorption component 12. The rotating components are connected to the adsorption components 12. After the adsorption component 12 adsorbs the battery cell, the rotating component drives the adsorption component 12 to rotate, thereby changing the orientation of the adsorption component 12 and thus adjusting the orientation of the battery cell.

[0056] During the movement of the solar cells, external factors such as vibration and friction may cause the cells to deflect or change their orientation. This not only affects the alignment accuracy of the cells after separation but also adversely impacts subsequent shingling processes. To address these issues, a rotating component corresponding to the adsorption component 12 was designed. After the adsorption component 12 has adsorbed the solar cells, the rotating component drives the adsorption component 12 to rotate, adjusting the orientation of the solar cells to restore them to their ideal state. With the intervention of the rotating component, the orientation of each solar cell can be precisely adjusted, meeting the technical requirements of the shingling process. This not only ensures the quality of the solar cells after shingling but also improves the performance consistency of the photovoltaic panel.

[0057] Specifically, the rotating assembly includes a rotating shaft, a housing 122, and a limiting rod. The rotating shaft is connected to the adsorption assembly 12, and its rotation drives the adsorption assembly 12 to rotate and adjust its position. The housing 122 is fitted over the rotating shaft, and a limiting hole is formed on the housing 122. One end of the limiting rod is connected to the rotating shaft, and the other end passes through the limiting hole from inside the housing 122.

[0058] The rotating shaft drives the adsorption assembly 12 to adjust the rotation of the solar cells. Simultaneously, a limiting rod connected to the rotating shaft passes through a limiting hole and prevents excessive rotation of the shaft by contacting the hole, thus limiting the rotation of the shaft. This limiting function effectively prevents excessive rotation of the rotating shaft due to program errors or control system malfunctions, thereby preventing the solar cells from rotating too far. This design ensures that adjacent solar cells do not collide, improving safety during production.

[0059] Fourth Implementation Method

[0060] The fourth embodiment of this application also discloses a reference. Figure 4 The photovoltaic panel stacking machine shown includes the aforementioned photovoltaic panel feeding mechanism. The photovoltaic panel stacking machine also includes a stacking welding machine. The photovoltaic panel feeding mechanism is connected to the stacking welding table, and the photovoltaic panel feeding mechanism feeds the solar cells to the stacking welding table for welding.

[0061] The photovoltaic panel feeding mechanism efficiently separates the solar cells from the glass panel through rising and falling movements, simplifying the separation process by avoiding excessive mechanical travel. The separated cells are then precisely transported to the lamination welding station for welding. Because the cells are pre-positioned before entering the lamination welding machine, the positioning step can be omitted during transport, effectively reducing the time the cells spend inside the machine and optimizing the lamination welding process. This design also provides a stable foundation for subsequent lamination welding processes. During welding on the lamination welding station, the cells are no longer interfered with by the glass panel, significantly improving welding speed and quality. This design results in more robust and higher-performing laminated solar cells.

[0062] Finally, it should be noted that those skilled in the art will understand that many technical details have been presented in the embodiments of this application to facilitate a better understanding of the present application. However, even without these technical details and various changes and modifications based on the above embodiments, the technical solutions claimed in the claims of this application can be substantially achieved. Therefore, in practical applications, various changes can be made to the above embodiments in form and detail without departing from the spirit and scope of this application.
