Development and Application of Machine Vision

The functional characteristics of machine vision are gradually improved and developed with the development of industrial automation. As the manufacturing industry's demand for automation continues to improve production quality and management, China's demand for machine vision is also rising. Machine vision has now developed into a bright and dynamic industry with an average annual growth rate of more than 20%. Its application range is very wide, covering almost all industries of the national economy, including industry, agriculture, medicine, military, aerospace, meteorology, Astronomy, public security, security, etc.

Machine vision applications include identification and detection. Identification is the process of determining which product (part, object, target, etc.) belongs to a given type. Inspection is the process of determining that a product (part, object, target, etc.) deviates from a given set of standards. So let's take a look at which fields machine vision is used in practice.

it

a. Recognition of IC surface characters and inspection of pin number, discrimination of long and short feet, detection of distance between pins;

b. Fast positioning of electronic components on high-speed placement machines;

c. Inspection of a small amount of foreign matter and defects on precision electronic components, to determine whether a single wafer is qualified or not; etc.

Packaging industry

a. Read the barcode on the surface of the packaging bag and detect the production date;

b. Inspection of the shape and packaging of tablets in the production of tablets;

c. Inspection of wall thickness and appearance during capsule production; etc.

Automobile industry

a. During the production of connectors in automotive electronics, high production efficiency and dimensional accuracy of the finished product are required, and the vision system can perform online inspection of the workpiece for 24 hours;

b. Counting the number of balls in the production of bearings, detecting ball gaps and inspecting the damage of balls and inner and outer rings

c. In the production of bearing seals, check the welding finish and whether there are depressions, cracks, swellings and irregular colors;

d. Detection and application of engine identification, final assembly, etc .;

Machinery manufacturing industry

a. External dimension detection of components;

b. Assembly integrity testing;

c. Part positioning and posture recognition;

d. The same-color concave character recognition of parts, engines, and chassis lamp numbers; etc.

Agricultural Production

a. Grain and foreign matter detection, sorting and color selection;

b. beverage liquid detection;

c. Character recognition of production date and shelf life;

d. Detection of breakage and cleanliness of empty bottles on the filling line; etc.

Customs and ports

a. Fingerprint, palm print, iris and face recognition;

b. Cargo identification;

c. Security inspection of dangerous goods; etc.

Special inspection

a. Cable wear and damage detection;

b. Detection of containers and pipelines;

c. Amusement facility speed detection;

d. Online detection of dangerous equipment; etc.

Machine vision products

In addition, machine vision is also widely used in integrated circuit inspection, aerospace, military defense, firefighting, highway transportation, and so on. Vevision has more than ten years of machine vision automated inspection experience. It has been focusing on industrial vision and automation technology The promotion and innovation of machine vision and image processing technology are aimed at solving practical problems for customers in industrial production.

The birth and application of machine vision has greatly liberated human labor, improved the level of production automation, and improved the living conditions of human beings. It has a good application prospect.
