Chip defect vertical visual inspection equipment

Abstract

The invention relates to the field of chip detection, and particularly relates to chip defect vertical visual inspection equipment. A feeding device of a material box conveying mechanism conveys a material box to be detected to a material box filling mechanism. A material box clamping jaw of the material box filling mechanism clamps the material box and enables a material strip in the material boxto be aligned with a material strip clamping jaw of the material strip conveying mechanism; the material strip clamping jaw clamps the material strip and enables the material strip to move to a to-be-detected position along the first clamping part and the second clamping part; the first clamping part and the second clamping part clamp the material strip to wait for visual detection of the chip; acamera of the detection mechanism shoots the material strip and detects the gold thread on the material strip through existing computer image recognition software; traditional manual gold thread detection is replaced; the gold thread detection efficiency and the detection accuracy of the chip material strip are improved; and meanwhile, the material strip is located on the detection datum plane inthe visual detection process, the included angle between the detection datum plane and the horizontal plane is 60 to 70 degrees, and bending deformation of the light and thin material strip under theaction of gravity is reduced to the maximum extent.

Description

technical field [0001] The invention relates to the field of chip detection, in particular to a chip defect vertical visual detection device. Background technique [0002] In the production process of the chip material bar, it is necessary to detect the gold wire on the material bar, so as to detect whether there is a manufacturing defect in the material bar in time. The detection of chip gold wires on unmolded material strips mainly involves: gold wire missing detection, gold wire bending detection, redundant gold wire detection, gold wire short circuit detection, gold wire open circuit detection and gold wire surrounding impurities detection, etc. . At present, the detection content of gold wire is mainly completed by human eye observation detection or manual detection combined with electron microscope. Therefore, the manual or semi-manual detection method not only has high labor intensity and low work efficiency, but also the detection accuracy varies from person to per...
