Description

Technical Field

[0002] As users pay more and more attention to the quality of products, manufacturers' quality control of products has become increasingly strict. Before products leave the factory, in order to ensure their quality, manufacturers will conduct appearance inspections on each product to ensure that there are no scratches, damages and other defects on the product surface.

[0003] Taking a keyboard as an example, the keyboard contains multiple keys, and each key has 5 surfaces, including the front surface, the back surface, the left surface, the right surface and the top surface. Before the keyboard leaves the factory, the manufacturer must conduct appearance inspections on each surface of each key to ensure that each surface of the key is intact. At present, the commonly used detection method by manufacturers is through vision detection equipment. Specifically, the keyboard is placed inside the equipment, and then camera components are placed on each surface of the keyboard keys to ensure that visual images can be generated on each surface of the keys, so as to facilitate the analysis by the equipment system. From the design of the above vision detection equipment, it can be seen that multiple camera components need to be placed inside each equipment, which undoubtedly results in a relatively large volume of the entire equipment, occupying a large amount of production site space.
