Endoscope is a set of electronic, optical, mechanical and other technologies in one of the high-tech testing products, generally can be divided into fiber-optic endoscopes, rigid rod mirror, electronic video endoscopes. At present, the most widely used in the field of industrial endoscopes or electronic video endoscopes. Its front-end pipeline goes deep into the internal parts, through the front LED or rear fiber-optic light guide system to provide lighting conditions, the human eye can not directly observe the equipment or parts of the internal real-time observation and photography, video. In general, the imaging of electronic video endoscopy and camera principle is similar: the light signal reflected from the surface of the object to be measured through the lens transmission to the image sensor (CCD or CMOS), so that the optical signal into an electrical signal, and after processing, and ultimately be converted into a digital signal, the image data is color correction, white balance processing and other post-processing, encoding for the camera supported by the The image data is post-processed for color correction, white balance, etc., encoded into the data formats supported by the camera, such as image format, resolution, etc., and stored as image files.
Two, how to choose the industrial borescope
Users through the industrial borescope can directly see the human eye can not see the area, as people pay more and more attention to the quality of products, defect detection of industrial parts has become a very important topic. So how to choose the industrial endoscope?
First of all, you need to understand the basic working environment, is it in a high-temperature environment? There is no oil, liquid? Another thing is to look at the specific use of the situation, such as the frequency of use (taking into account the wear and tear of the lens), the minimum diameter of the inspection port (to determine the diameter of the probe), the minimum bending radius (taking into account the probe's steering, turning situation), the detection depth (to determine the length of the pipeline) and so on. Then there is the question of price, which can be evaluated according to the company's budget accordingly. Then it is to confirm the manufacturer's qualification, certification, warranty, after-sales, reputation and other related issues, whether to provide prototype and so on, comprehensive decision-making.
Three, the use of endoscopes
The use of industrial endoscopes is very broad, from the production of industrial equipment and components, manufacturing, installation to the maintenance of the latter part of the whole process are often able to be applied. Such as the internal surface defect detection of castings, pipeline or boiler weld, corrosion, rust, excess detection, internal machining defects in parts and components inspection, equipment internal structure and operation state detection, aircraft, automobiles, ships and other means of transportation, such as regular maintenance and overhaul. Industrial endoscope is a kind of equipment and components can be disassembled without the premise, through the observation hole into the engine and other parts of the internal exploration, and effectively record the corresponding data, can effectively improve the detection efficiency, relatively accurate.
Fourth, the use of endoscopes Precautions
It is important to note that before use, be sure to read the manual, and strictly in accordance with the requirements of operation and storage. Industrial endoscope as a precision optical instrument, the lens belongs to the easy to damage devices, in the use of the process should pay particular attention to avoid collision and scratching. Avoid excessive bending of the pipeline, so as not to cause damage to the internal optical fiber. Before and after use, it is best to use a special dust-free cloth dipped in a small amount of alcohol to wipe to ensure that the lens and pipeline clean.
