The main function of the machine vision detection, location and measurement. Machine vision system relative to the artificial or mechanical means, has a number of advantages of speed, high precision and accuracy. The development of industrial modernization, machine vision has been widely used in various areas to provide better product quality and perfect solution for enterprises and users.
At present, the application of machine vision detection and robot vision:
1 Detection: a qualitative or semi-quantitative detection (for example, visual inspection of the product can be divided into a high-precision quantitative detection (e.g., a photomicrograph of cell classification, the mechanical component size and position measurement) and without Scale on the assembly line. Parts identification positioning, defect detection and assembly of complete detection).
The 2 robot vision: for guidelines robot operation and action in a wide range, as sent from the hopper messy the workpiece heap picking the workpiece according to the orientation on the conveyor belt or other device (hopper picking) . As for the small-scale operation and action, but also by means of tactile sensing technology.
In other countries, the universal application of machine vision is mainly reflected in the semiconductor and electronics industry, about 40% -50% of which are concentrated in the semiconductor industry. Specific, such as PCB printed circuit: the production of various types of printed circuit board assembly technology, equipment; single, double-sided, multi-layer circuit boards, CCL and the required materials and accessories; ancillary facilities and supplies, ink, pharmaceutical medicine, accessories; electronic packaging technology and equipment; screen printing equipment and screen surrounding materials. SMT Surface Mount: SMT process equipment, welding equipment, test equipment, repair equipment and various tools and accessories, SMT materials, tablets paste, adhesives, flux, solder and oxidation oil, solder paste, cleaning agents; reflow welding machine, wave soldering machines and automated production line equipment. Electronic production and processing equipment: electronic component manufacturing equipment, semiconductor and integrated circuit manufacturing equipment, components molding equipment, electronic engineering mold. All aspects of machine vision systems are still quality testing has been widely used, and its products occupy a pivotal position in the application. In addition, machine vision is also used in other fields.
In the industrial field for IC size measurement, measure the length and spacing of the IC pin. IC pin is relatively fragile parts in the production and transmission process will be due to an unexpected operation and bent, folded, broken problem.
Applications in the industry, mainly in the pharmaceutical, packaging, electronics, automotive, semiconductor, textile, tobacco, transportation, logistics, and other industries, machine vision technology to replace the manual production efficiency and product quality. For example, in the logistics industry, machine vision technology can be used to express sorting classification does not appear most of the courier company manual sorting, reducing the failure rate of an article, you can improve sorting efficiency, reduce manual labor.
