The MVC Solar Vision Inspection System is designed to detect silicon wafers and cell dies from all production lines. The MVC solar vision inspection system can detect 5" and 6" sizes and can detect single crystal, polycrystalline or even quasi-single crystal finished products. The reliability of PV modules is a very important factor in many important factors that can help the PV industry move toward "the same price of electricity." The failure of some PV modules in the initial stage of installation often comes from poor appearance in the photovoltaic cell stage, such as edge nicks, surface flaking, or aluminum bumps. These flaws have become a very important issue for PV cell manufacturers when quality is being checked. Therefore, for the quality and reliability of photovoltaic modules, silicon wafers and cell wafer defects are very important.

In addition, due to the increasing application of "photovoltaic building integration" and the application of "home roof installation", even those such as water marks or dirt that have no direct impact on reliability will be It becomes a defective product with visual paralysis.
Traditionally, all the cockroaches were screened by visual inspection. However, because the human eye is prone to fatigue and the detection standards are inconsistent, the use of machine vision automated inspection systems on the production line to replace manual shift detection is an increasingly attractive alternative to appearance inspection.
The MVC Solar Vision Inspection System is designed to detect silicon wafers and cell dies from all production lines. The MVC solar vision inspection system can detect 5" and 6" sizes and can detect single crystal, polycrystalline or even quasi-single crystal finished products. According to different production processes, a total of eight different functions of visual inspection system equipment can be used for "silicon wafer feed" inspection or "screen printing" inspection or even "battery shipment" inspection and other purposes.
Solar silicon wafer appearance and surface contamination detection equipment can be used to detect silicon wafer length, width, diagonal, edge angle, lead angle and lead angle, as well as surface flaw detection. The well-designed software and operating interface allow the user to set different test parameters to achieve the test results, as well as the display and storage functions for future analysis and integration of MES/CIM.
Solar Silicon Wafer Quality Inspection Equipment To provide the highest repeatability of lattice size inspection results, the MVC system uses a unique optical design on the silicon wafer inspection equipment to enhance the lattice characteristics. When the lattice size can be quantified, the classified silicon wafers can be applied to different production processes and used in different cell production lines to improve the average conversion efficiency when the cell is produced.
The 7202 can also detect holes. The hole hole is the cause of the μ-crack or severe local shunting that causes the solar module to fail.
Solar Silicon Wafer Saw Marking Equipment Cutting line saw marks are caused by impurities during cutting or by vibration of cutting lines. Sometimes it occurs at the edge and it is also possible to occur in the middle of the silicon wafer. Since the device is optically designed using the inspection method of EN 50513 2009, even the cutting line saw marks occurring at the center of the silicon wafer can be correctly detected.
Solar cell color sorting equipment is designed to provide highly reproducible cell color separation results. Thanks to the color space of the CIE 1931 Lab and the division of the cell into a color detection area of ​​up to 60X60, the system can provide color information for nearly 3,600 areas for parameter setting during color sorting. Through various color information and user-defined color separation methods, even non-uniform color distribution like polycrystalline or non-uniform anti-reflective layer thickness can be precisely defined.
The system can also be used after the anti-reflective coating process to ensure that only cells that have been uniformly coated are screen printed. At the same time, the cells with uneven coating can be saved for heavy work. The system can be integrated on a line-by-line sorter or on an off-line battery sorter before shipment.
Front side printing and surface contamination detection equipment for solar cells The front side of solar cells may cause adverse effects on appearance or reliability. Therefore, such as "the missing silver paste of the main gate line", "gate line break", "print offset", "water mark", etc., all need to pass the reliable and high accuracy optical inspection instrument (AOI). To filter to maintain the highest quality of the shipped battery. The front-facing printing and surface inspection machine is equipped with a high-resolution camera and an excellent software algorithm to screen out the positive flaws you want to block.
The device can be installed after the screen printing process to warn the line to pay attention to the cleaning time of the screen or the addition time of the slurry, and to eliminate the failed printed cells. This can also improve the IV test in the latter stage and the output speed of the sorting process. The equipment can also be integrated on a line-by-line sorter or off-line battery sorter.
Solar cell backside printing and surface contamination detection equipment The backside printing of solar cells may cause undesirable effects on the appearance or reliability. Among all the back printing defects, the aluminum bump generated by the abnormal screen printing process will cause extremely high breakage rate during the module packaging process. The backside printing and surface inspection machine uses a special light source design to detect common back prints, even aluminum tabs.
Solar Cell Anti-Reflective Coating Test System This system is an automated optical inspection machine for inspecting anti-reflective coatings. Thanks to the 4M black and white camera and RGB light source design, the system ensures that each anti-reflective coating can be detected by different light sources and imaging components.
