Machine Vision System: A great tool for quality control

The Machine Vision System (MVS) is an automation tool that collects and analyzes constantly updated images to coordinate production (such as controlling robots), process assessment and early warning implementation, and the system has many unique advantages to become a quality control tool.

MVS can capture images of each product and based on a given standard sample, the system will calculate the rate of deviations in color, size and compared to those samples for analysis. If the rate of deviation exceeds the permitted level, the product will be regarded as failing to meet quality standards. For these products, the system also provides employees with control over why the product is not up to the job so that it can be adjusted during production.

Through this mechanism, MVS has shown many advantages for product quality control: Fast product inspection speed, accurate results and not affected by other factors such as human; Ability to statistically error of products to help adjust the stages in the manufacturing process; Can be combined with an automated sorting system to help eliminate defective products without humans; Improving labor productivity, reducing labor for product inspection, thereby reducing production costs.

MVS technology is currently being used to meet the needs of many different industries, such as:

• Printing industry: For labels and printed packaging products, the accuracy of colors, characters, images is required. The quality control system with images can fully meet these requirements.
• Plastic industry: In the plastic molding process, the existence of burrs on the products often occurs due to errors in the molding and installation of molds. With the visual control system, products with screens are automatically sorted and removed. On the other hand, Products that require flatness during production, the use of images to control product quality is workable.
• Food and beverage industry: With beer and beverage production systems, it is mandatory to have a few employees sitting down to check for foreign objects in bottles. When using a visual inspection system, this job is not required.
• Precision mechanical industry: In the field of mechanical engineering, there are many devices that apply image technology to check the contours of the part after processing.
• Electronics industry: In the field of electronics, the visual circuit board inspection has been in use for a long time, this test system helps prevent defective or missing components.
