AI Technical Summary

Technical Problem

In existing technologies, inspecting the surface of a chip's protective film for defects such as damage, scratches, bubbles, or foreign matter requires visual inspection or the use of magnifying glasses or microscopes. This necessitates individually removing the chip for observation, resulting in low detection efficiency.

Method used

A chip protective film damage detection device was designed. The chip is carried through a sealed box by a transmission belt. Powder is evenly spread on the chip surface. Combined with a light and a high-definition camera to capture the differences on the chip surface, the device automatically locates the damaged position and quickly extracts the chip through a limiting sleeve.

Benefits of technology

It achieves efficient and automated chip protective film damage detection, reducing manual observation time and improving detection accuracy and efficiency.

Abstract

This utility model relates to the field of protective film detection technology, specifically a chip protective film damage detection device. It includes a processing table and an auxiliary roller movably fitted onto the inner wall of the processing table. A sealed box is detachably installed on the inner wall of one side of the processing table. A blower is fixedly installed on the bottom inner wall of one side of the sealed box, and an air cylinder is fixedly installed on the output end of the blower. An arc-shaped corner is provided on the top inner wall of the sealed box, positioned at the top edge of the air cylinder. When the chip moves to the outside of the sealed box, the blower blows away dust from the chip surface. The smooth surface of the chip allows powder to be blown off, while some powder remains on the chip surface due to the unevenness caused by the scratches. Because the chip surface is relatively smooth, the traces of powder flow are very obvious.
