A color difference detection device and method of using the same

Abstract

The invention discloses a color difference detection device and a use method thereof, comprising a feeding mechanism, a control system, a classification mechanism and a detection mechanism; the detection mechanism includes at least one detection channel, and each detection channel includes a transfer unit, a visual guide device, a color difference detection mechanism, and a self-inspection device; the transfer unit includes a carrier and a drive unit that controls the movement of the carrier; the self-inspection device is used for the calibration of the visual guidance device and the color difference detection mechanism, which includes a calibration plate and an automatic Gripper inspection cylinder, the calibration plate is fixed on the carrier, and the calibration plate is covered with a detachable dust cover; the invention has a self-inspection device, which can realize the self-inspection of the color difference of the equipment itself, and avoid the trouble of color difference judgment Deviation increases the accuracy of detection; it can carry out objective, accurate, efficient and quantitative analysis and classification on the color, size and defects of products, which meets the needs of modern production equipment.

Description

technical field [0001] The invention relates to the technical field of color difference identification, in particular to a color difference detection device and a method for using the same. Background technique [0002] At present, in the production process of industrial products, the types of products are diversified and the products are made into different colors; at this stage, domestic enterprises mainly rely on manual visual inspection or low-precision gray cards, colorimeters and other equipment for product color detection. , leading to the instability problem caused by subjective and objective factors in color difference judgment: [0003] (1) There are subjective factors in manual visual inspection, which are easily affected by vision, light, emotion, etc., and long-term human eye sorting will inevitably cause human eye fatigue, which will lead to a decrease in work efficiency or an increase in false detection rate; [0004] (2) Manual visual inspection and ordinary...

Problems solved by technology

[0002] At present, in the production process of industrial products, the types of products are diversified and the products are made into different colors; at this stage, domestic enterprises mainly rely on manual visual inspection or low-precision gray cards, colorimeters and other equipment for product color detection. , leading to the instability problem caused by subjective and objective factors in color difference judgment:

[0003] (1) There are subjective factors in manual visual inspection, which are easily affected by vision, light, emotion, etc., and long-term human eye sorting will inevitably cause human eye fatigue, which will lead to a decrease in work efficiency or an increase in false detection rate;

[0004] (2) Manual visual inspection and ordinary inspection equipment will be affected by objective factors such as environmental light source, observation angle, background color, etc.;

[0005] (3) It may be difficult to distinguish colors with small color differences. The color difference sorting of photovoltaic cells mainly relies on human eyes for identification, which not only has low accuracy and takes a long time, but also has low efficiency and high cost of manual sorting;

[0006] (4) There are certain safety hazards in manual entry into the production line, high labor costs, certain errors in manual detection, and detection data can only be recorded manually, and transmission feedback cannot be implemented
