The installation of glass on the windows and doors is the need for daylighting. Most of the previous use of flat glass, now, the novel and wonderful "embossed glass" is also increasingly applied to the building. The embossed glass has various patterns such as squares, dots, diamonds, etc., which are very beautiful.
The optical properties of embossed glass are different from those of flat glass. It is very clear to see through the flat glass, and nothing can be seen through the embossed glass. Because of its embossing pattern, it is actually a combination of various lenses and prisms, which can refract, reflect and diffuse light in different directions. After the light is reflected and refracted by the embossed glass, it becomes quite disordered and cannot be imaged, so it cannot be seen through it. The doors and windows of the bathroom and toilet are equipped with embossed glass, which can make the room light enough, but the outdoor people can't see the room, so you can not hang the curtains! The embossed glass is pressed, and its strength is ten times larger than that of ordinary flat glass. The color of embossed glass is varied, it can add brilliance to buildings, so it is very versatile. Offices, classrooms, operating rooms, restaurants, clubs, and doors and windows on the ground floor of the street are suitable for the installation of embossed glass. Similar to embossed glass, there is frosted glass. This side of the glass is the same as fine sandpaper, and the hair is rough, so it is called the frosted glass. Frosted glass and embossed glass, the optical properties of the two are not the same, except that the "lens" and "prism" on the frosted glass surface are much smaller, so the light reflected, refracted and diffused by the frosted glass is more Evenly gentle. Use embossed glass or frosted glass as the cover of the electric lamp, which can hide the glare light bulb inside, even if the eyes directly look at the light, it will not feel dazzling. The special optical properties of embossed glass also play a role in automotive headlights. In the past, car headlights used flat glass as a lampshade, which transmitted a narrow beam of light. Driving at night, the driver can only use the beam to see where the beam shines. Almost everything near it is invisible, which brings great inconvenience to the driving work. Besides, the bright spot is swaying, the darkness is dark, the contrast is too big, and it is easy for the driver to dizzy. In addition, when the car is driving, the car body is always shaken, and the light of the headlights is constantly changing rapidly. The driver adapts to this. Changes, the eyes are also prone to fatigue. For this reason, the lighting designer used the frosted glass as the front lampshade. As a result, although the illumination range has been expanded, there are still disadvantages. Due to the diffuse astigmatism of the frosted glass, some of the light is scattered to the top and was wasted in vain. Later, the designers used the embossed glass with horizontal and vertical stripes to make the front lampshade, which overcomes this shortcoming.
As with other glass manufacturing processes, embossed glass substrates are prone to defects during the production process. Let the "invisible" defects be invisible: as with other glass manufacturing processes, defects in the production of embossed glass substrates are prone to occur. However, the detection and identification of these defects is obviously more challenging, even the more subtle defects (such as stones and open cells) must be reliably identified and distinguished. This is the limit of the results of all other vision systems. Automated optical real-time inspection technology is compatible with the following systems: PATTERNSCAN sheet monitoring system for embossed glass sheet inspection; and PATTERNSCAN sheet system for solar glass sheet inspection; both systems are capable of finer defects Conduct reliable detection, classification and differentiation. With the help of these two systems, you will be able to provide higher quality embossed glass for specific market needs. The PATTERNSCAN production line is breaking many records. In less than a year, we have sold 50 inspection systems to manufacturers in the solar industry, which are mainly concentrated in Asia. Manufacturers such as Xinyi Glass and CSG have already ordered this advanced solution for optimizing quality. The PATTERNSCAN sheet system is a fully automated optical system for the inspection of embossed glass sheets. This system is designed to be tested in a more efficient manner and can be placed directly after the annealing kiln and cold end. It is difficult to detect and identify defects (usually open and closed bubbles, stones and nodules) in such harsh environments. But PATTERNSCAN still works quickly, reliably and efficiently. PATTERNSCAN sheet system: inspection solution for embossed glass sheets. To ensure that the solar protection glass is flawless, this system is usually immediately after the cleaning zone. Both systems use innovative multi-mode, multi-view source technology developed by ISRAVISION. Multiple views have multiple lighting combinations in the camera library. Multi-mode refers to multiple light source modes. It also incorporates multi-dimensional technology that identifies and distinguishes all defects in glass interiors, glass surfaces and glass edges, as well as glass coatings. Through the continuous development and upgrading of the software platform, these two PATTERNSCAN systems ensure that the embossed glass meets the higher quality of the photovoltaic industry market standards. As part of the modular suite's standard features, the distinction between defects, including open and closed bubbles and tiny flaws and scratches, can achieve the best results no matter where they are located. In short: the flaws that were previously undetectable and difficult to distinguish are now able to be tested and categorized with the help of PATTERNSCAN. This patented light source assembly consists of an ultra-fast LED with independent switching, and its original combination is the first in the industry. In theory, an unlimited number of different views can be generated simultaneously using only one camera or one camera library. This technology has reached an unprecedented level of detection in defect detection and classification. The inspection software utilizes defect data collected from various views to perform reliable and comprehensive defect classification in real time. Cutting optimization based on defect classification significantly increases production and material savings throughout the production line. Accurate test results will benefit users, not only the performance of the product is greatly improved, but also the necessary hardware is significantly reduced. The lower operating costs of the PATTERNSCAN sheet inspection system and the PATTERNSCAN sheet inspection system not only result in improved profitability, but also process optimization. The apparently significant gap between the detection technology requirements and the short return on investment (ROI) time is reduced.
