Description

Technical Field

[0001] This invention belongs to the field of photovoltaic module mass production technology, specifically relating to a method, system and related apparatus for mass production of fully series-parallel shingled photovoltaic modules. Background Technology

[0002] The production equipment for ordinary shingled photovoltaic modules all adopts the method of first assembling "vertical shingled cell units" and then combining multiple sets of "vertical shingled cell units" into shingled photovoltaic modules. During the production process, the surface of the cells is not inspected, resulting in the cells having some defects. Without corresponding remedial repairs, they are directly placed into the cell array, causing defects in the photovoltaic modules or even scrapping the entire module. Therefore, there are many shortcomings in terms of yield and production speed, making it impossible to achieve mass production of fully series-parallel shingled photovoltaic modules. Summary of the Invention

[0003] This invention provides a method, system, and related apparatus for mass production of fully connected parallel shingled photovoltaic modules, which solves the technical defect of the prior art that does not perform relevant surface inspection on the cells, resulting in the produced cells having some defects. Without corresponding remedial repairs, they are directly placed into the cell array, causing defects in the photovoltaic modules or even the scrapping of the entire module.

[0004] To achieve the above objectives, the present invention employs the following technical solution: Firstly, a method for mass production of fully series-parallel shingled photovoltaic modules is provided, including: The batch of solar panels are simultaneously sliced ​​to obtain solar cells, and the solar cells are placed in a loading plate; Obtain the image information of the battery cell in the loading plate to determine whether the battery cell is intact; The intact solar cells are then coated with adhesive, and the coated solar cells are arranged using a shingled module.

[0005] Furthermore, the batch of solar panels are simultaneously sliced ​​to obtain solar cells, and the solar cells are placed in a loading plate, specifically including: A batch of solar panels are arranged sequentially on a slicing rack so that multiple solar panels are on the same horizontal line, and multiple solar panels are fixed in place using fixing devices on the solar panels. Cutting devices are arranged on both sides of the slicing rack, and multiple cutting devices are arranged along the entire length of the slicing rack. Multiple cutting devices are electrically connected to the control system, and by setting a program, the multiple cutting devices can perform slicing operations synchronously to obtain battery cells. Using a gripping device, the battery cells are placed sequentially on a loading plate.

[0006] Furthermore, the solar panel has multiple smaller solar panels of the same size, with gaps between adjacent smaller solar panels; When the cutting device cuts the solar panel, the cutting end of the cutting device cuts along the entire length of the slit.

[0007] Further, obtaining the image information of the battery cell in the loading plate and determining whether the battery cell is intact specifically includes: An image acquisition device and a flipping device are installed on the top of the feeding plate. The acquisition end of the image acquisition device faces the top of the feeding plate, and the flipping device is used to flip the battery cells. After the solar cell is placed in the loading plate, the flipping device and the image acquisition device start synchronously. The flipping device clamps and fixes the solar cell and flips it over, while the image acquisition device acquires an image of the surface of the solar cell. The collected battery surface image information is compared with the battery cell surface information pre-stored in the database. If a defect is identified on the surface of the currently collected battery cell, the battery cell is placed in the repair area of ​​the loading plate. If the surface of the currently collected battery cell is identified as complete, the cell is transported to the next workstation using a conveying device.

[0008] Furthermore, the image acquisition device is a camera.

[0009] Furthermore, the intact solar cells are treated with adhesive, and then arranged using a shingled module. Specifically, this includes: Using dispensing equipment, multiple complete solar cells are simultaneously dispensed, and then the dispensed solar cells are arranged using shingled modules.

[0010] Secondly, a fully series-parallel shingled photovoltaic module is provided, including a photovoltaic module body, which is mass-produced using the method described above.

[0011] Thirdly, a mass production system for fully serial and parallel shingled photovoltaic modules is provided, including: The cutting module is used to simultaneously slice batches of solar panels. The image acquisition module is used to acquire image information of the battery cells and determine whether the battery cells are intact. The dispensing module is used to dispense adhesive onto cells that are determined to be intact. Shingled modules are used to arrange the solar cells after they have been coated with adhesive.

[0012] Fourthly, an electronic device is provided, including a memory, a processor, and a computer program stored in the memory and executable in the processor, wherein the processor executes the computer program to implement the steps of the mass production method for fully serial-parallel shingled photovoltaic modules as described above.

[0013] Fifthly, a computer-readable storage medium is provided, the computer-readable storage medium storing a computer program, which, when executed by a processor, implements the mass production method of the fully serial-parallel shingled photovoltaic modules as described above.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. After obtaining the solar cells, this mass production method can perform comprehensive visual inspection of the solar cells by acquiring their image information. It can also fully detect whether there are any defects or surface defects on the solar cells, effectively eliminating the occurrence of defective products during the mass production process. Solar cells that can be repaired can be maintained in a timely manner, solving the problem of the entire photovoltaic module being scrapped.

[0015] 2. By using synchronous slicing operations, the cutting time of solar panels can be significantly shortened, thereby improving production efficiency. The automated operation of the gripping device reduces manual intervention and further increases production speed. The high precision and synchronization of the cutting device can ensure that the cut solar panels have consistent shape and size. As the cutting device and gripping device work together, the utilization rate of the equipment and production efficiency are improved.

[0016] 3. Cutting along the slit can speed up the cutting process because the cutting device does not require additional positioning or adjustment on the solar panel, which helps to shorten the production cycle and improve production efficiency. The smoother cutting process also makes the operation of the cutting device more stable. This reduces production downtime caused by equipment failure or shutdown.

[0017] 4. By comparing the surface information of the solar cells with pre-stored data in the database, defects such as cracks, scratches, and stains can be accurately identified. This helps to promptly detect and address quality issues, preventing defective products from entering subsequent production stages. Secondly, after identifying defective solar cells, they can be placed in the repair area of ​​the loading plate for repair, or screened according to quality requirements. This ensures that the quality of solar cells entering the next workstation meets production requirements. The automated inspection process reduces manual intervention and lowers labor costs. Simultaneously, automated inspection reduces misjudgments and omissions caused by human factors, improving inspection accuracy.

[0018] 5. As an image acquisition device, the camera can adapt to the inspection needs of solar cells of different specifications and sizes. By adjusting the camera's focal length, exposure, and other parameters, clear imaging and accurate inspection of different solar cells can be easily achieved.

[0019] 6. Adhesive dispensing and shingled modules help improve the conversion efficiency and power generation performance of photovoltaic modules. Adhesive dispensing ensures a tighter connection between cells, reducing energy loss due to poor connections. Shingled modules, by optimizing the arrangement of cells, achieve zero cell spacing, allowing more cells to be placed in the same area, thereby increasing the light-receiving area and conversion efficiency of the photovoltaic module.

[0025] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present 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, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0028] The production equipment for ordinary shingled photovoltaic modules all adopts the method of first assembling "vertical shingled cell units" and then combining multiple sets of "vertical shingled cell units" into shingled photovoltaic modules. During the production process, the surface of the cells is not inspected, resulting in the cells having some defects. Without corresponding remedial repairs, they are directly placed into the cell array, causing defects in the photovoltaic modules or even scrapping the entire module. Therefore, there are many shortcomings in terms of yield and production speed, making it impossible to achieve mass production of fully series-parallel shingled photovoltaic modules.

[0029] To address the aforementioned technical deficiencies, the inventors have provided a method, system, and related apparatus for mass production of fully serial and parallel shingled photovoltaic modules.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings: Firstly, this embodiment provides a method for mass production of fully series-parallel shingled photovoltaic modules, such as... Figure 1 As shown, the method includes: S101. A batch of solar panels is simultaneously sliced ​​to obtain solar cells, which are then placed on a loading plate. For example, the batch of solar panels is arranged sequentially on a slicing rack so that multiple panels are on the same horizontal line, and the panels are fixed using fixing devices on the panels. Cutting devices are arranged on both sides of the slicing rack, with multiple cutting devices arranged along the length of the rack. These cutting devices are electrically connected to a control system, and a program is set to enable them to perform slicing operations synchronously, thereby obtaining solar cells. Each solar panel has multiple smaller solar panels of the same size, with gaps between adjacent panels. When cutting the panels, the cutting end of the cutting device cuts along the length of the gaps. Cutting along the gaps speeds up the cutting process because the cutting device does not require additional positioning or adjustment on the panels, helping to shorten the production cycle and improve production efficiency. The smoother cutting process also makes the operation of the cutting device more stable. This reduces production interruption time due to equipment failure or downtime. Then, a gripping device is used to place the solar cells sequentially onto the loading plate. In this process, the cutting time of the solar panels can be significantly shortened by synchronous slicing, thereby improving production efficiency. The automated operation of the gripping device reduces manual intervention and further improves production speed. The high precision and synchronization of the cutting device can ensure that the cut solar panels have consistent shape and size. As the cutting device and the gripping device work together, the utilization rate of the equipment and production efficiency are improved.

[0031] S102. Obtain image information of the battery cells in the loading plate and determine whether the battery cells are intact. For example, an image acquisition device and a flipping device are installed on the top of the loading plate. The image acquisition device is preferably a camera, with the acquisition end of the image acquisition device facing the top of the loading plate. The flipping device is used to flip the battery cells. After the battery cells are placed in the loading plate, the flipping device and the image acquisition device are started synchronously. While the flipping device clamps and fixes the battery cells and flips them, the image acquisition device acquires images of the surface of the battery cells. The acquired battery surface image information is compared with the battery cell surface information pre-stored in the database. If a defect is identified on the surface of the currently acquired battery cell, the battery cell is placed in the repair area of ​​the loading plate. If the surface of the currently acquired battery cell is identified as complete, the battery cell is transported to the next workstation using a conveying device. By comparing the surface information of the solar cells with pre-stored data in the database, defects such as cracks, scratches, and stains can be accurately identified. This helps to promptly detect and address quality issues, preventing defective products from entering subsequent production stages. Secondly, after identifying defective cells, they can be placed in the repair area of ​​the loading plate for repair or screened according to quality requirements. This ensures that the quality of solar cells entering the next workstation meets production requirements. The automated inspection process reduces manual intervention and lowers labor costs. Furthermore, automated inspection reduces misjudgments and omissions caused by human factors, improving inspection accuracy.

[0032] S103. Apply adhesive to the intact solar cells and arrange the adhesive-treated cells using a shingled module. For example, using an adhesive dispensing device, multiple intact solar cells are simultaneously adhesive-treated, and the adhesive-treated cells are arranged using a shingled module. The adhesive dispensing process and the shingled module help improve the conversion efficiency and power generation performance of the photovoltaic module. The adhesive dispensing process ensures a tighter connection between the solar cells, reducing energy loss due to poor connections. The shingled module, by optimizing the arrangement of the solar cells, achieves zero-spacing solar cells, allowing more solar cells to be placed in the same area, thereby increasing the light-receiving area and conversion efficiency of the photovoltaic module.
