With the continuous growth of global demand for renewable energy, the photovoltaic industry, as an important component of clean energy, is developing rapidly. As the core component of photovoltaic systems, the production efficiency and quality of photovoltaic modules are crucial to the overall performance of the photovoltaic system. In order to achieve efficient and stable production of photovoltaic modules, semi-automatic production lines have become the choice of many photovoltaic enterprises. So, what are the equipment for semi automated production lines of photovoltaic modules?

　　What are the equipment for the semi-automatic production line of photovoltaic modules? Firstly, it is necessary to know the module production process. The module production process includes sorting, slicing, string welding, layout, stacking, EL appearance inspection, lamination, edge trimming, EL inspection, framing, junction box installation, curing, and IV inspection.

1. Solar cell sorting equipment: Solar cell sorting equipment is a device used to detect and classify solar cells. Its main function is to inspect the solar cells before producing components to ensure that the quality and performance of the cells meet the requirements, which helps to improve production efficiency and product quality. 2. Cell slicing machine: A cell slicing machine is a device used to cut solar cells into the required size and shape. It is usually used on solar cell production lines to divide large panels into small pieces for subsequent processing and assembly.

　　3. Solar cell string welding machine: It is a device used to connect solar cells into a string. It is usually used in the production process of solar panels to form a series circuit of multiple battery cells in a certain order and connection method. It should be noted that the specific specifications and functions of the equipment may vary depending on different manufacturers and models.

　　4. Solar cell typesetting machine: a device used to arrange solar cells in a certain way to form solar panels. It is usually used in the production process of solar panels, where multiple battery strings are arranged into a whole according to certain rules and connection methods.

　　5. Battery module layering: After arranging the battery in series, lay other auxiliary materials, such as glass, cut EVA, and backboard, in a certain layer and prepare for the next layering. (Laying level: from bottom to top: glass, EVA, battery, EVA, back panel). Ensure the relative position between the battery string and materials such as glass during laying, adjust the distance between the batteries, and lay a solid foundation for lamination.

　　6. EL appearance defect detector: mainly used to detect defects inside or on the surface of photovoltaic cells or modules. Based on the principle of electroluminescence, the EL defect detector can quickly and accurately detect internal defects of modules, such as cracks, hot spots, and cell breakage, by observing the electroluminescence images of photovoltaic modules. The EL testing before lamination is to test all semi-finished battery panels. If problems are found, defective solar cells can be replaced in a timely manner. In addition, appearance inspection is also important.

　　7. Battery module laminating machine: Place the stacked component string, glass, EVA, and backplate into the laminating machine, extract the air inside the components through vacuum pumping, and then heat to melt the EVA, bonding the battery, glass, and backplate together; Finally, cool down and remove the components. This is a crucial step in component production, and the lamination temperature and time are determined by the properties of EVA.

　　8. Trimming: mainly used to remove burrs formed during the lamination process due to the outward extension and solidification of EVA due to pressure after melting.

　　9. EL detection: mainly used to detect defects inside or on the surface of photovoltaic cells or modules. By observing the electroluminescence image of photovoltaic modules based on the principle of electroluminescence, internal defects such as cracks, hot spots, and cell breakage can be quickly and accurately detected. Used for EL final detection to prevent problematic components from reaching customers.

　　10. Install frame and junction box: Use aluminum alloy frame. The main purpose of framing is to increase the strength of the components. In addition, framing can also seal electrical components and extend their lifespan. The gap between the frame and the glass is filled with silicone resin. Glue a box at the back lead of the component to facilitate the connection between the battery and other devices or batteries. And pour glue into the junction box to ensure it is waterproof and dustproof.

　　11. In the manufacturing process of photovoltaic modules, module curing is an essential step. Curing is the process of forming a strong bond between materials such as backboards, battery cells, EVA, and glass under certain temperature and time conditions, ensuring that components have stable performance and long lifespan.

　　12. Component IV tester: By measuring the voltage and current characteristics of photovoltaic modules, the IV tester can evaluate their power and efficiency, and determine the quality level of the module. It also plays a crucial role in ensuring the performance and quality of photovoltaic modules.

　　These devices play a crucial role in semi automated production lines, not only improving production efficiency and reducing production costs, but also ensuring product quality. With the continuous progress of technology and changes in market demand, the semi-automatic production line equipment for photovoltaic modules is also constantly being updated, providing more choices and possibilities for the production of photovoltaic modules.

　　Please note that when selecting and using these devices, it is necessary to fully consider factors such as production scale, product characteristics, production efficiency, etc., to ensure that the equipment can meet production needs and maximize efficiency. At the same time, it is also necessary to pay attention to market dynamics and technological development trends, timely introduce and update equipment, in order to maintain competitive advantage and market position.
