Application:
Defect Detection:
Utilizing advanced Electroluminescence (EL) imaging technology, this system detects a variety of defects in solar cell strings—including cracks, black spots, misalignment, and other imperfections—that can impact solar panel performance. It serves as an excellent electroluminescence test sale solution, offering reliable el tester image acquisition for quality inspections.
High Efficiency and Fast Testing:
Designed for rapid testing, the machine completes inspections in ≤2 seconds per string (excluding loading/unloading), making it ideal for high-speed environments. Its el tester with large display ensures that operators can quickly review detailed images, which is crucial for any Solar panel production line where fast and accurate quality control is a must.
Specifications:
| Items | Functions |
| Defect Detection Types | The equipment is engineered to identify a wide range of defects—including hidden cracks, black spots, misalignment, broken grids, cold solder joints, light/dark spots, bright spots, and scratches. This makes it an ideal electroluminescence test sale solution for maintaining high quality on a Solar panel production line. |
| Cell Types | Compatible with both monocrystalline and polycrystalline silicon solar cell strings, ensuring versatility in various manufacturing setups. |
| Efficiency | Guarantees an efficiency of ≥99%, ensuring that every test delivers consistent and accurate results essential for high-quality output on a Solar panel production line. |
| Applicable String Specifications | Designed for solar cell strings with dimensions of 1350 x 300 mm, this system is perfectly tailored for standard Solar panel production line applications. |
| Testing Cycle | The system completes tests in ≤2 seconds per string (excluding loading and unloading time), enabling rapid throughput ideal for high-speed production. |
| Camera | Equipped with 4 industrial-grade cameras, this setup is optimized for el tester image acquisition to ensure comprehensive defect detection. |
| Camera Resolution | Each camera features a 5 million pixel high-definition sensor paired with an NIR industrial-grade lens. The imaging time is adjustable from 0.3 to 2 seconds for precise data capture. |
| Shutter Type | Utilizes an electronic, non-mechanical shutter to improve reliability during continuous el tester image acquisition on the production line. |
| Photographing Method | Direct illumination is employed to capture clear EL images, ensuring defects are readily visible for operator review. |
| Power-On Method | The system is manually powered on, allowing for controlled startup procedures typical in an electroluminescence test sale setup. |
| Computer | Comprises a dedicated industrial computer host alongside a display system featuring a 29-inch or larger 1080p monitor, which supports el tester with large display functionality for detailed image analysis. |
| Management Software | The software includes automatic EL image shooting, barcode scanning, and manual input functions. It enables defect classification, automatic date folder generation, and image saving with uniformity correction, ensuring high-quality results for Solar panel production line operations. |
| Abnormal Rate | The system maintains an abnormal rate of less than 1/200,000, ensuring stable and continuous operation even in rigorous production environments. |
| Testing Software | The software automatically stitches images seamlessly (without hardware stitching), supports automatic image capture and saving, offers configurable image save paths, and allows adjustment of optimization parameters (time, gain, contrast, Gamma, BR Max/Min) with permission settings for modifications. |
| Detection Effect | Effectively displays EL defects such as hidden cracks, black spots, misalignment, broken grids, cold solder joints, light/dark spots, bright spots, and scratches, enabling operators to make prompt quality assessments. |
| Electrode Module | Features a dual-module, dual-position voltage block that is manually positioned on the lead line for testing, adding flexibility to the inspection process. |
| DC Power Supply Model | ZL6010 |
| Testing Ampere | Operates within a range of 0-60V for testing purposes. |
| Testing Voltage | Adjustable between 0-10A, catering to various testing requirements. |
