Problems solved by technology

[0003] In particular, the appearance inspection of mobile phones is time-consuming and labor-intensive. Manual inspection faces the problems of difficult recruitment, inconsistent inspection standards, and unstable first-hand delivery rate. In response to this market demand, our company has specially launched standard middle-frame appearance inspection equipment. Different models The color, material, and production process of the middle frame of the mobile phone are all different, which bring great challenges to the visual imaging. At present, with the advancement of technology and the increasingly fierce market competition, many appearance defects have higher requirements for image quality. It is getting higher and higher, especially for the imaging of the corner of the middle frame. Generally, the interpolation movement of the mechanism is adopted, and the camera is used to take pictures on the fly. This way of taking pictures has the defects of poor precision and uneven feed speed, which leads to a decline in image quality. , affects the detection rate of defects. The current image acquisition device uses the method of linear and semi-circular segmental fitting for interpolation to do semi-circular motion, which requires the cooperation of 3 motors. This method leads to high cost and poor accuracy. , uneven feed speed, complex programming and a series of problems will inevitably have a greater impact on mechanism design and imaging quality
