The glass cover of a mobile phone is the outermost glass of the touch screen. With the rise of smartphones, glass covers are widely used in the electronics industry. They are attached to the surface of touch screens to protect the screen and beautify products. The automatic detection of cover defects in the field of smartphones is considered a technological bottleneck that has plagued the industry for many years. The detection of surface defects in products requires high detection accuracy and reliable lighting effects to ensure, especially for the detection of glass cover plates after lamination, which is more difficult. At present, the device can detect white film and silk screened cover plates, and is compatible with the detection of 3D glass cover plates. It can also detect defects in car glass screens and TFT-LCDs.

This product provides an electrostatic discharge testing system and method for LCD display panels. It uses a six axis robot to hold an electrostatic gun and discharge and eliminate static electricity according to the set point, replacing the previous manual operation of holding the electrostatic gun. It reduces the repetitive actions of operators, avoids fatigue from holding the gun for a long time, improves detection efficiency, and to a certain extent, can improve testing accuracy, accuracy, and consistency.
