【Hot attention of Chemical Machinery Equipment Network ] Chains are generally metal links or rings, which are mostly used for mechanical transmission and traction.
Chain-shaped objects used to obstruct traffic passages (such as at the entrance of streets, rivers or harbors), chains used for mechanical transmission.
Pitch generally refers to the chain pitch, that is, the center distance between chain rollers.
It can also be used to refer to gear pitch and thread pitch.
Indicates the distance between corresponding points on the contours of two adjacent threads.
Pitch is the most important parameter of the chain.
When the pitch increases, the size of each structure in the chain increases correspondingly, and the power that can be transmitted increases accordingly.
The larger the pitch, the stronger the carrying capacity, but the lower the transmission stability, the greater the dynamic load caused.
Therefore, a small-pitch single-row chain should be used as much as possible in the design, and a small-pitch multi-row chain can be selected for high-speed heavy loads .

Recently, Zhejiang Province* used machine vision technology to help Hangzhou Donghua Chain Group solve the problem of chain pitch measurement.
Technicians have developed a dual-camera-based chain pitch detection device, using automatic transmission and dual-camera image processing methods to achieve detection automation, simple operation, high stability, and a strong market prospect.
This device not only improves the detection efficiency of chain pitch, but also provides strong support for digital detection in Zhejiang Province.

The machine vision system refers to the capture of images through machine vision products (ie image capture devices, divided into CMOS and CCD), and then transmits the image to the processing unit, through digital processing, according to pixel distribution and brightness, color and other information , To determine the size, shape, color, etc.
Furthermore, according to the result of the discrimination, the operation of the on-site equipment is controlled.

Machine vision technology is an interdisciplinary subject involving many fields such as artificial intelligence, neurobiology, psychophysics, computer science, image processing, and pattern recognition.
Machine vision mainly uses computers to simulate human vision functions, extract information from images of objective things, process and understand them, and finally use them for actual detection, measurement and control.
Machine vision technology* is characterized by fast speed, large amount of information, and multiple functions.
Machine vision mainly uses computers to simulate human visual functions, but it is not just a simple extension of the human eye, but more importantly, it has a part of the function of the human brain to extract information from the image of objective things, process and understand it.
It is finally used for actual detection, measurement and control.

The machine vision industrial inspection system is divided into two categories, quantitative and qualitative inspection, in terms of its inspection nature and application scope, and each category is divided into different sub-categories.
Machine vision is very active in various application fields of industrial online inspection, such as: visual inspection of printed circuit boards, automatic flaw detection of steel plate surfaces, measurement of parallelism and perpendicularity of large workpieces, detection of container volume or impurities, automatic identification and classification of mechanical parts, and Geometric size measurement, etc.
In addition, in many occasions that are difficult to detect by other methods, the use of machine vision systems can be effectively implemented.
The application of machine vision is increasingly replacing people to complete many tasks, which undoubtedly improves the level of production automation and the intelligence of the inspection system to a large extent.

A typical industrial machine vision application system includes the following parts: light source, lens, CCD camera, image processing unit (or image capture card), image processing software, monitor, communication/input output unit, etc.
First, the camera is used to obtain the image signal of the measured target, and then it is converted into a digital signal through A/D conversion and sent to the * image processing system.
According to the pixel distribution, brightness and color information, various operations are performed to extract the characteristics of the target, and then Then output the judgment result according to the preset judgment criterion to control the drive actuator to carry out corresponding processing.
Machine vision is a comprehensive technology, including digital image processing technology, mechanical engineering technology, control technology, light source lighting technology, optical imaging technology, sensor technology, analog and digital video technology, computer software and hardware technology, man-machine interface technology, etc.
Machine vision emphasizes practicability and requires that it can adapt to the harsh environment of the industrial site.
It must have reasonable cost performance, universal industrial interfaces, high fault tolerance and safety, and strong versatility and portability.
It puts more emphasis on real-time, requiring high speed and high precision.

The use of testing equipment for quality testing can provide real-time reports and detailed and complete analysis reports of the entire testing process.
On-site operators can make timely adjustments to the problems in the work based on the timely alarms of the fully automatic testing equipment and real-time analysis reports.
Perhaps the reduction will not only reduce the scrap rate by one percentage point.
The managers can rely on the analysis report of the testing results.
Tracking the production process is more conducive to the management of production technology.
Because the high-quality testing equipment required by customers not only stops at detecting the quality of printed matter, but also requires the ability to analyze afterwards.
What some quality testing equipment can do can not only improve the qualified rate of finished products, but also assist the manufacturer to improve the process flow, establish a quality management system, and achieve a stable quality standard.
