Inspection principle

3C product logos are all printed on the product, but due to the process, the printed logo usually has certain printing defects, such as printing misalignment, missing printing, wrong printing, etc., which seriously affects the appearance and brand of the product overall image.

In response to such problems, many companies use manual inspection to inspect the quality of printed products, but due to the inevitable mistakes in the human inspection process, it will lead to a large number of missed inspections, wrong inspections and manual damage, and the increasing labor costs are also increasing. It has become a major constraint factor for the scale expansion of manufacturers.

Issue&solutions

• Reflection problem: Due to the high surface finish of the material, a high-gloss mirror surface has been formed. Even if the light source is in a weak state, the reflection on the surface will have a very strong contrast. This contrast will remove impurities, scratches, and grinding on the surface itself. The coverage of defects such as scratches makes it impossible to detect surface defects of parts by visual photography.
• Reflection problem: Since the surface of the material has formed a mirror surface, the general optical lens and the lamp beads of the visual light source will form a reflection on the surface of the material. This reflection will be imaged on the final inspection screen, which will seriously affect the imaging effect of the material surface, causing Detection cannot be performed.

Based on years of experience in machine vision inspection projects, KEYE TECH has concluded a mature system solution, which is mainly used to solve the detection of logo defects on the surface of electronic products. At present, it is mainly used in the detection of surface defects of domestic product logos and mobile phone shell logos.

Application range

1. Detection of bruises, wounds, and gaps
2. Scratch defect detection
3. Defect detection for crushing and dents
4. Pinhole defect detection
5. Corrosion point, white point, pitting defect detection
6. Dirty defect detection
7. Grinding mark defect detection
8. Material line, material pattern defect detection
9. Convex hull defect detection, etc.

It can be applied to defect detection in the electronics industry, such as wearable product surface defect detection, tablet computer Logo defect detection, etc., and can also be applied to high-brightness and mirror surface defect detection such as medical devices.
