Typical applications of machine vision in the automation industry

[ Focus on Chemical Machinery Equipment Network ] Automation technology is developing rapidly in our country.
People have a deeper understanding of machine vision, and their views on it have also undergone a great change
.
The machine vision system has improved the degree of automation of production, made dangerous working environments unsuitable for manual operations possible, made mass and continuous production a reality, and greatly improved production efficiency and product accuracy
.
The ability to quickly obtain information and automatically process it also provides convenience for information integration in industrial production
.
With the maturity and development of machine vision technology, it is not difficult to find that its application range is becoming wider and wider.
According to these fields, we can roughly summarize the five typical applications of machine vision.
These five typical applications can also basically summarize the application of machine vision technology.
The role that can be played in industrial production
.

 

1.
Image recognition application
 

Image recognition is the use of machine vision to process, analyze and understand images to identify targets and objects in various patterns
.
The most typical application of image recognition in the field of machine vision industry is the recognition of two-dimensional codes.
Two-dimensional codes are the most common one of our usual barcodes
.
Store a large amount of data information in this small two-dimensional code, and track and manage the product through the bar code
.
Through the machine vision system, the barcode on the surface of various materials can be easily identified and read, which greatly improves the efficiency of modern production
.

 

　　2.
Image detection application
 

　　Inspection is one of the most important applications in the machine vision industry.
Almost all products need to be inspected.
Manual inspection has many disadvantages.
The accuracy of manual inspection is low.
If you work for a long time, the accuracy cannot be guaranteed.
The slow speed easily affects the efficiency of the entire production process
.
Therefore, machine vision is also very widely used in image detection, such as the detection of characters on the edge of a coin
.
In the fifth set of RMB issued in October 2000, the side of the one-yuan coin has an enhanced anti-counterfeiting function.
In view of the strict control requirements of the production process, a visual inspection system was installed in the last process of coinage
.
In addition, it can also be used for color registration and color comparison inspection in the printing process, printing quality inspection of beverage bottle caps in the packaging process, barcode and character recognition on product packaging, and defect detection of glass bottles
.
Among them, the defect detection of glass bottles by the machine vision system also includes the category of medicinal glass bottles.
That is to say, machine vision also involves the medical field.
Its main inspections include size inspection, bottle body appearance defect detection, and bottle shoulder defect detection , bottle testing
.

 

　　3.
Visual positioning application
 

　　Visual positioning requires the machine vision system to quickly and accurately find the tested part and confirm its location
.
In the field of semiconductor packaging, the equipment needs to adjust the pickup head according to the chip position information obtained by machine vision, accurately pick up the chip and bind it.
This is the most basic application of vision positioning in the machine vision industry
.

 

　　4.
Object measurement application
 

　　The biggest feature of machine vision industrial applications is its non-contact measurement technology, which also has high-precision and high-speed performance, but non-contact and wear-free, eliminating the hidden danger of secondary damage that may be caused by contact measurement
.
Common measurement applications include gears, connectors, auto parts, IC component pins, twist drills, and Luoding thread testing
.

 

　　5.
Object sorting application
 

　　In fact, the application of object sorting is based on a link after recognition and detection, and the image is processed through a machine vision system to achieve sorting
.
In machine vision industrial applications, it is often used for food sorting, automatic sorting of surface defects on parts, and cotton fiber sorting
.
