The invention discloses an optical appearance inspection device and an appearance inspection method. The device adopts two Z-direction high-precision optical camera lens assemblies suspended on an X-axis bridge frame, and two parallel workbenches along the Y-axis are arranged under the bridge frame. An overturning mechanism is set between the two workbenches, a loading container and an unloading container are respectively set on the outside of the two workbenches, and two sets of X-axis transmission components are set and the grabbing components are vertically suspended on the workbench, the overturning mechanism, Above the feeding container and the unloading container, the structural arrangement is highly integrated and centralized; the detection of the front and back of the material on the two Y-axis workbenches is completed in a streamlined manner, and the closely arranged equipment main body is on the X-axis and Y-axis The linear motor and high-precision linear guide rail are used as the driving body in the direction drive, which meets the high-precision movement requirements of the main body of the equipment and also guarantees the stability of the platform, thus providing a basic guarantee for highly sophisticated optical components.
Description
technical field [0001] The invention relates to the field of optical inspection of circuit boards, in particular to an optical appearance inspection device and an appearance inspection method. Background technique [0002] With the rapid development of optoelectronics, communication electronics, computers, machinery, materials and other industries, IC substrates have also developed rapidly. In modern electronics and communication products, IC substrates and PCB circuit boards can be seen almost everywhere, as small as one Chips, large to ultra-large integrated PCBs, IC substrates and PCB boards are the pillar industries in the current and future electronics industry. Due to the rapid development of the IC substrate industry, the product technology of IC circuit boards has also been greatly improved. Most of the products are highly integrated and ultra-fine lines, so customers have put forward higher requirements for product quality. The entire production process of the boar...
