It is used in the fields of condition monitoring, finished product inspection and quality control. Because of its high precision,...
Machine vision is to use the machine instead of the human eye to make measurements and judgments. By converting the subject into an image signal, it is transmitted to the image processing system for various calculations to make various judgments. The whole machine vision system is made up of many parts, and the importance of the camera in the entire visual system is very obvious. So, in industrial production, what are the requirements for a complete machine vision system for industrial cameras?...
The robot walking circuit is composed of two units of a driving circuit and a forward and reverse circuit of the DC motor. The circuit constitutes the robot walking circuit by using the multi-resonant circuit composed of 555, the synchronous counter 74LS196, the seven-segment decoder 74LS248, the double JK flip-flop and other basic unit circuits through the cascade combination of the above basic circuits. The circuit effectively realizes the walking and retreating of the robot, and controls the...
Market competition promotes the development of machine vision In the modern industrial automation production, it involves a variety of inspection, measurement and part identification applications, such as automatic positioning of components of electronic assembly lines, printing quality inspection of beverage bottle caps, bar code and character recognition on product packaging, and the like. The common feature of this type of application is the continuous mass production and the very high...
In daily work, we will be exposed to many aspects of measurement problems, such as bottle cap detection, product surface defect detection, etc. In the production line, relying on people to make such measurements and judgments will be due to fatigue, personal differences, etc. Errors and errors are generated, but the machine goes on tirelessly and steadily. This had to introduce the concept of a machine vision system, a so-called machine vision systems, refers to the human eye in place of using...
Thanks to the patented vision system, PET bottle testing is no longer a "puzzle game" on Sidel's blow molding machine. Sidel's large-capacity bottle blowing machine introduced pressco's Intellispec BNS vision inspection system. This latest PET bottle inspection system inspects all Sidel-made containers for important parts of the container (bottom, bottle neck, bottle wall, and The top edge of the bottle is thoroughly checked. The real-time data collected from the tests are continuously...

Machine vision system analysis A typical vision system generally includes a light source, an optical system, a camera, an image processing unit (or image acquisition card), an image analysis processing software, a monitor, a communication/input/output unit, and the like. ■ Image acquisition The acquisition of the image is actually the conversion of the visualized image and intrinsic features of the measured object into data that can be processed by the computer, which directly affects the...
For pharmaceutical companies, various regulations and routine production practices need to more accurately grasp the information in the production process. In addition, from an economical point of view, companies also hope that production will be more efficient. For the labels of pharmaceutical products, it is necessary to indicate the batch number, production date, and instructions for use. One of the big problems with this is that devices that are sensitive enough to accurately detect and...
1, automatic print quality inspection The detection system used in the automatic print quality inspection equipment is to first take a standard image using a high-definition, high-speed camera lens, and set a certain standard on this basis; then, the image to be detected is taken and the two are compared. The CCD linear sensor converts the change in the light quantity of each pixel into an electronic signal. After the comparison, if the detected image is different from the standard image, the...
