Description

TECHNICAL FIELD

[0002] In the production and manufacturing process of integrated circuit chips, efficient and accurate detection of the chips is a key link to ensure product quality. With the continuous expansion of the application field of integrated circuit chips, the market demand for chips continues to grow, which puts higher requirements on the chip detection efficiency.

[0003] To meet the efficient detection requirements, some detection tools use the design idea of setting multiple detection cameras corresponding to multiple rows of chips on the tray to realize the synchronous detection of multiple rows of chips and greatly improve the detection efficiency. However, this detection method has very high requirements for the accuracy of the tray loading position. At present, a mechanical hand is commonly used to assist in loading, but in the actual operation process, due to the precision limitation of the mechanical structure, the deviation of the control algorithm and external environmental interference and other factors, the loading position is not accurate. This may result in the situation that the camera cannot accurately correspond to multiple rows of chips, so that some chips cannot be effectively detected, reducing the accuracy and reliability of the detection.
