AI Technical Summary
Technical Problem
After the chips are split, existing technologies fail to effectively distinguish between qualified and unqualified chips, resulting in wasted capacity of the chip-removing machine.
Method used
By acquiring images of the target strip after the wafer splitting is completed, the location information of qualified chips is determined, and the chip adsorption device in the wafer picker is controlled to pick up the chips, thus avoiding the picking of unqualified chips.
Benefits of technology
This increased the production capacity of the chip picker, avoided picking up defective chips, and improved equipment efficiency.

Abstract
The application provides a qualified chip sorting method, a chip taking machine, a computer device and a medium. The method comprises the following steps: obtaining a target bar after the splitting is completed; when a chip taking instruction for the target bar is received, an image of the target bar is obtained; based on the image, position information of the qualified chip on the target bar is determined; based on the position information, a chip adsorption device in the chip taking machine is controlled to perform chip taking processing on the qualified chip on the target bar. After the splitting is completed, the position information of the qualified chip on the target bar is determined based on the image of the target bar, and then the chip taking is performed based on the position information of the qualified chip, so that only the qualified chip is taken, the chip taking of unqualified chips is avoided, and the production capacity of the chip taking machine is improved.
