Industrial Control Summary: The main functions of machine vision include detection, positioning, and measurement. Compared to manual or traditional mechanical methods, machine vision systems offer a range of advantages, including higher speed, higher precision, and higher accuracy. With the development of industrial modernization, machine vision has been widely applied in various fields, providing enterprises and users with superior product quality and perfect solutions.
Currently, machine vision is mainly applied in two areas: inspection and robot vision.
1. Inspection: This can be further divided into high-precision quantitative inspection (such as cell classification in micrographs, and measurement of the size and position of mechanical parts) and qualitative or semi-quantitative inspection without measuring instruments (such as product appearance inspection, component identification and positioning on assembly lines, defect detection and assembly completeness inspection).
2. Robot vision: Used to guide robot operations and actions over a large area, such as picking up workpieces from a jumbled pile of workpieces from a hopper and placing them in a specific orientation on a conveyor belt or other equipment (i.e., the hopper picking problem). For operations and actions within a small area, tactile sensing technology is still needed.
Abroad, the widespread application of machine vision is primarily seen in the semiconductor and electronics industries, with approximately 40%-50% concentrated in the semiconductor sector. Specific applications include: PCB (Printed Circuit Board): various PCB assembly technologies and equipment; single-sided, double-sided, and multi-layer circuit boards, copper-clad laminates and related materials and accessories; auxiliary facilities, consumables, inks, chemicals, and accessories; electronic packaging technology and equipment; screen printing equipment and related materials. SMT (Surface Mount Technology): SMT processes and equipment, soldering equipment, testing instruments, rework equipment, various auxiliary tools and accessories, SMT materials, mounting plates, adhesives, fluxes, solder and anti-oxidation oils, solder paste, cleaning agents, etc.; reflow soldering machines, wave soldering machines, and automated production line equipment. Electronic manufacturing equipment: electronic component manufacturing equipment, semiconductor and integrated circuit manufacturing equipment, component forming equipment, and electronic molds. Machine vision systems have also been widely applied in various aspects of quality inspection, and their products occupy a crucial position in these applications. In addition, machine vision is used in various other fields.
In the industrial field, IC size measurement involves measuring the length and spacing of each IC pin. IC pins are relatively fragile components, and during production and transportation, they can be bent, damaged, or broken due to accidental handling.
In terms of industry applications, machine vision technology is mainly used in pharmaceuticals, packaging, electronics, automobile manufacturing, semiconductors, textiles, tobacco, transportation, and logistics. Replacing manual labor with machine vision technology can improve production efficiency and product quality. For example, in the logistics industry, machine vision technology can be used for sorting and classifying express packages, eliminating the need for manual sorting currently used by most express companies. This reduces the damage rate of items, improves sorting efficiency, and reduces manual labor.
