Description

[0002] The traditional crystalline silicon solar module industry faces overcapacity and increasingly prominent issues of homogeneous competition. Developing high-efficiency solar cell modules is an effective way to solve this problem. Heterojunction perovskite tandem solar cells are the next generation of photovoltaic cells after crystalline silicon and thin-film cells. They possess many advantages, including higher limiting photoelectric conversion efficiency, higher power per unit area, stable power generation performance, simple solution processing technology, excellent performance in extreme weather, and integration with building materials. Silicon cells, tempered glass, and encapsulation materials are stacked in different sequences and then laminated to form a laminate. One end of the lead wire extends from the lead hole of the upper encapsulation material and is connected to the junction box for installation. The usual welding method is to place the junction box on the photovoltaic module located on the conveyor belt and weld it using welding equipment.

[0003] During the transport of photovoltaic (PV) modules on a conveyor belt, to prevent them from shifting off-center and causing blockages, each PV module needs to be inspected and aligned. Currently, this is typically done manually by workers adjusting the relative position of the silicon wafers to the conveyor belt. However, this method is not only time-consuming and labor-intensive, leading to reduced efficiency, but it also easily damages the PV modules and has low positioning accuracy. Utility Model Content

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example

[0028] Reference Figures 1-4 As shown, a correction device of this utility model includes:

[0029] The device body encloses a processing space, and has an input port 2 and an output port 2 respectively on both sides along the first direction. The processing space is connected to the outside world through the input port 2 and the output port 2.

[0030] The conveying mechanism 18 is disposed along the first direction through the input port 2, the processing space and the output port;

[0031] The straightening mechanism 4 is respectively arranged on both sides of the conveying mechanism 18 along the second direction, including: support members arranged on both sides of the conveying mechanism 18, a straightening frame 21 movably connected to the support members along the second direction, and a plurality of first rollers 22 arranged along the first direction and rotatably connected to the straightening frame 21. The plurality of first rollers 22 are arranged on the straightening frame 21 along the first direction.

[0032] A stop mechanism is provided on both sides of the conveying mechanism 18 along the first direction and is used to stop the photovoltaic modules to be welded on the conveying mechanism 18.

[0033] The alignment device described in this utility model uses a conveying mechanism 18 to transport the photovoltaic module to be welded, so that the photovoltaic module to be welded is moved from the input port 2 through the receiving space 3 and out of the output port. When the photovoltaic module to be welded reaches the welding station, the photovoltaic module is stopped by a stop mechanism, so that the photovoltaic module is positioned along the first direction. The alignment mechanism 4 is set to align the photovoltaic module located in the receiving space 3. Multiple first rollers 22 on both sides are set along the first direction, so that the angle of the photovoltaic module is aligned along the first direction. The alignment frames 21 on both sides of the conveying mechanism 18 are close to the conveying mechanism 18, so that the rollers are in contact with the photovoltaic module to be welded and push the photovoltaic module to keep the photovoltaic module upright and avoid tilting.

[0034] Reference Figures 3-4As shown, the conveying mechanism 18 consists of multiple sets, each including: a drive motor 9, a drive wheel 10, and a conveyor belt 11. The drive wheels 10 are respectively arranged on both sides of the device body along a first direction. The conveyor belt 11 is respectively connected to the drive wheels 10 on both sides. The output end of the drive motor 9 is connected to at least one drive wheel 10. The conveyor belt 11 connects the drive wheels 10 on both sides to form a closed loop structure. The output end of the drive motor 9 is connected to at least one drive wheel 10. When the drive motor 9 starts, it transmits power to the drive wheel 10. The drive wheel 10 rotates and drives the conveyor belt 11 to move, thereby realizing the conveying of the photovoltaic modules to be welded.

[0035] Continue to refer to Figures 3-4 As shown, multiple sets of conveyor belts 11 are arranged in parallel. The drive wheels 10 on the same side of the multiple sets of conveyor belts 11 have the same center line. The output end of the drive motor 9 is connected to a drive shaft 12. The drive wheels 10 on one side of the multiple sets of conveyor belts 11 are all fixedly sleeved on the drive shaft 12. The parallel arrangement of multiple sets of conveyor belts 11 can evenly distribute the weight of the photovoltaic modules to be welded, and ensure that the modules are subjected to uniform force in the horizontal direction during the conveying process, thereby keeping the modules in a stable conveying state. It also allows one drive motor 9 to drive the drive wheels 10 on one side of multiple sets of conveyor belts 11 simultaneously using the drive shaft 12. Through the connection of the drive shaft 12, the power of the drive motor 9 can be evenly distributed to multiple drive wheels 10, thereby driving multiple sets of conveyor belts 11 to run synchronously. This not only simplifies the drive structure, reduces the number of drive motors 9, and reduces costs, but also enables multiple sets of conveyor belts 11 to move synchronously.

[0036] Reference Figure 3 As shown, the device body is provided with a first linear drive component 25, and the alignment frame 21 is connected to the output end of the first linear drive component 25. The alignment frame 21 is movably connected to the device body along a second direction via a sliding pair 19. The second direction is perpendicular to the first direction, and both the second direction and the first direction are located on the same horizontal plane. The first linear drive component 25 is selected as either a linear motor or a cylinder; in this embodiment, it is a linear motor, which has the advantage of high alignment accuracy. The sliding pair 19 consists of a guide rail and a slider. The guide rail is a high-precision linear guide rail, such as a ball bearing linear guide rail. The linear guide rail is installed on the device body and fixed by bolts. When the alignment frame 21 moves along the second direction under the action of the first linear drive component 25, the balls roll on the track surface, thereby achieving low-friction, high-precision sliding motion. Stop plates 20 are also provided on both sides of the alignment frame 21. The stop plates 20 are located on the outer side of the slide rail to limit the alignment frame 21 externally.

[0037] Continue to refer to Figure 3As shown, it also includes a lifting mechanism 24, which includes: a second linear drive 13 disposed in the middle of multiple sets of conveying mechanisms 18, and a lifting frame 16 connected to the output end of the second linear drive 13. The second linear drive 13 is used to drive the lifting frame 16 to move along a third direction. The plane of the third direction is perpendicular to the horizontal plane. During the conveying and processing of the photovoltaic module to be welded, the lifting mechanism 24 lifts the module along the third direction to support the bottom of the photovoltaic module and prevent the photovoltaic module from tilting or shaking on the conveyor belt 11.

[0038] The lifting frame 16 is provided with a plurality of support plates 17, which are arranged along a first direction. Since the photovoltaic module has a large area, the arrangement of multiple support plates 17 along the first direction can disperse the supporting force on the module, making the module more stable during the lifting process and preventing damage or deformation of the module due to excessive local force. At the same time, the support plates 17 can be made of materials with low hardness and not easily deformed, so as to improve the positioning accuracy while avoiding scratching the photovoltaic module.

[0039] Continue to refer to Figure 3 , Figure 4 As shown, the stop mechanisms are respectively arranged around the multiple sets of conveying mechanisms 18, each including: a third linear drive 14 and a second roller 15. The third linear drive 14 is arranged on both sides of the conveying mechanism 18 along the first direction. The output ends of the second roller 15 and the third linear drive 14 are connected. The stop mechanisms at the front and rear ends are mainly used to stop at the beginning and end positions of the module conveying, so that the position of the photovoltaic module along the first direction is limited and determined.

[0040] The second roller 15 is rotatably connected to the output end of the third linear drive 14. The center lines of the first roller 22 and the second roller 15 are parallel. During the alignment process, the first roller 22 guides the module to alignment from the left and right sides. During the stopping process, the second roller 15 abuts against the front and rear ends of the photovoltaic module. During the alignment process, the first roller 22 and the second roller 15 are both rolled and connected to the side wall of the photovoltaic module. When the photovoltaic module turns, the first roller 22 and the second roller 15 roll on the side wall of the photovoltaic module. Example

[0041] This embodiment discloses a welding device for heterojunction perovskite solar cells, including the alignment device described in Embodiment 1. It also includes an input module 6, a display module 7, a control module, and a ventilation module 5. The control module is electrically connected to the input module 6, the display module 7, and the ventilation module 5. The device body includes a frame 23 and a housing. The housing has a receiving space 3, and the frame 23 is disposed within the receiving space 3. The conveying mechanism 18, the alignment mechanism 4, and the stop mechanism are all disposed within the receiving space 3.

[0042] This embodiment discloses a welding device for heterojunction perovskite solar cells. Various parameters of the welding device, such as stop time, alignment time, welding temperature, welding time, and conveying speed, can be set via an input module 6. The input module 6 includes a keyboard and mouse. A display module 7 is used to display the working status of the welding device, parameter settings, and potential fault information, including a display screen and fault indicators. A control module is electrically connected to the input module 6, display module 7, and ventilation module 5. The ventilation module 5 is used to promptly remove harmful gases or heat generated during the welding process of heterojunction perovskite solar cells and regulate the internal temperature of the equipment, maintaining a good working environment. The ventilation module 5 includes a ventilation fan and ventilation ducts. The ventilation ducts pass through the housing 1 and are connected to the outside and the housing space 3. The ventilation fan is installed inside the ventilation ducts to exhaust air. The control module receives the setting parameters from the input module 6 and controls the operation of various components such as the alignment mechanism 4 and the conveying mechanism 18 based on these parameters. Simultaneously, it sends the equipment's working status information to the display module 7 for display. In addition, the control module is also responsible for controlling the ventilation module 5 to ensure that the environmental conditions inside the equipment meet the welding requirements.

[0043] The welding equipment of this embodiment, with the above-described configuration, is adapted to the field of heterojunction perovskite tandem solar cell technology. Because the manufacturing of heterojunction perovskite tandem solar cells requires extremely high alignment precision for each component, the alignment mechanism in this welding equipment can accurately align the components to be welded, the stop mechanism can accurately fix the component positions, and the conveying mechanism can stably convey the components, ensuring that the precise alignment between each layer of cells and related components is not disrupted during the welding process of the tandem solar cell.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
