AI Technical Summary
Existing visual inspection devices typically use a single camera position for inspection, which makes it difficult to capture images of the entire chip at once. This can easily lead to the omission of defects or abnormalities in other parts of the chip, affecting the comprehensiveness and accuracy of the inspection.
The chip delivery mechanism, combined with an infrared sensor and a dual-camera system, uses an infrared sensor to control the main camera to capture images of the front of the chip, while the secondary camera of the side camera mechanism captures images of the sides of the chip. A servo motor drives a lead screw to control the secondary camera to follow the movement of the chip, thus achieving omnidirectional image acquisition.
It enables omnidirectional image acquisition of chips, improving the comprehensiveness and accuracy of detection, adapting to the needs of high-speed production, and ensuring that clear and stable images are continuously obtained during chip transfer.
