SMT Mounter Machine Vision Inspection and Sensor Technology

1. SMT mounter machine vision detection and sensor technology are widely used

The research direction of SMT mounter machine vision detection and sensor technology is the sensor and its signal detection device. Vigorously developing the research of vision detection and sensor technology is of great significance to the development of mechatronics technology.

Because of the advanced nature of machine vision in enhancing detectability and improving detection accuracy, with the improvement of the level of electromechanical automation technology, machine vision has been widely used in SMT components, SMT product quality inspection and other fields.

2. The advantages of SMT mounter machine visual inspection technology

Nowadays, basically all high-precision SMT mounter machine systems have a vision subsystem for positioning. These subsystems are used to detect and process the original position information of the target to obtain the feedback information needed by the computer and provide accurate data for precise component placement.

Visual inspection technology can accurately locate and calibrate the grasping of components. Because electronic components now have higher and higher requirements for placement accuracy, in high-precision microelectronic equipment, the new full-vision technology oriented to surface mount technology uses high-precision, high-speed image processing and feature extraction methods.

In addition, the use of visual technology can also carry out image recognition of mounted ICs for component classification and waste removal, etc., to improve the quality and efficiency of mounting.
