Description

Technical Field

[0002] After the glass substrate is processed and manufactured, it needs to be transported to the inspection production line via a conveyor rack for inspection. When detecting particles (such as glass powder or dust-like impurities) on the surface of the glass substrate, a particle counter (PAC) is required. The particle counter consists of a row of cameras in a linear array and LED lighting devices located at both ends of the camera device. In actual use, the glass substrate is transported to the bottom of the camera device via a conveyor belt. The LED device provides lighting, and the surface of the glass plate is scanned by the camera device to obtain particle count information on the surface of the glass plate. In actual use, the two LED lighting devices are fixedly installed at both ends of the camera device and cannot be adjusted.
