Information

On March 16, the "2021 China Laser Golden Glory Award" award ceremony hosted by Shanghai Optical Expo in Munich was successfully held in Shanghai. Congratulations to Tianhong Laser's "Large-size color-changing glass online defect laser repair system" for winning the "New Application Award" in this selection.

China Laser "Golden Glory Award"

The "China Laser Golden Glory Award" revolves around the three main categories of new technologies, new products and new applications, aiming to select works that are forward-looking, innovative and industry-driven in terms of technology or application, and are oriented towards the future of laser manufacturing. .

In line with the principle of fairness, justice and openness, in the expert review process, the organizer invited authoritative experts in the laser field, entrepreneurs, universities and scientific research institutes to form a jury panel, combined with the online voting situation, and then selected the major awards Winners list. The "Large-size color-changing glass online defect laser inspection system" participated in the selection by Tianhong Laser won the "2021 China Laser Jinyao Award New Application Award".

Celestica Award Winning Product Introduction

Large-size color-changing glass online defect laser inspection system

Electrochromatic glass is a new type of functional glass. It is a modern technological product that combines architectural aesthetics and energy saving. The tiny light transmission defects caused by impurities in the manufacturing process will affect the appearance and product life. Detection and removal Defects are an important process that is indispensable for producing products.

Electrochromism refers to the doping and dedoping of charged ions and materials under the action of an external power supply, resulting in oxidation or reduction reactions of metal oxide electrochromic materials, and then the optical transmittance, absorptivity, reflectivity phenomenon of reversible change. Electrochromic glass can intelligently control and adjust the transmittance, adjust the indoor light brightness and infrared radiation intensity, and reduce the energy consumption of air conditioning in summer.

Electrochromic coated glass is coated with one or more layers of metal and metal compound thin films on the glass surface. Defects in electrochromic glass coating directly affect the function of electrochromic glass. Electrochromic glass coating defects mainly refer to the existence of small particles of impurities inside the film layer, and the position of small particles of impurities cannot achieve discoloration, resulting in electric leakage and abnormal discoloration of the electrochromic glass.

This online defect laser repair system for large-size color-changing glass is mainly composed of an optical defect detection device, a laser repair device, and an online cradle-type fast scanning drive mechanism. Due to defects, the color-changing glass has problems such as increased current and local inability to change color.

1. The optical defect detection device consists of an 8k line scan camera, a high-brightness line light source and a um-level synchronous drive mechanism for high-speed zigzag scanning, recording the full-frame um-level resolution position image information, and detecting the characteristic defect position, eliminating background interference images ;

2. The laser repair device consists of a solid-state mw-level continuous green laser, a laser repair CCD area array camera and a coaxial objective lens, and a two-dimensional nanoscale precision motion axis. The CCD camera can detect the repair effect in real time, and the laser spot can automatically adjust the repair defect area ;

3. The cradle-type driving mechanism is driven by a three-axis ring-type direct-drive motor to realize high-speed 100mm layered scanning of a 3500X1700 format, without the need for fixture positioning and clamping, and to achieve online rapid large-format production.
