By the magic of medicine, people are used to apply endoscopes in various fields. Industrial endoscopes are used for observation of high temperature, toxic and harmful, nuclear radiation and places that are invisible to the human eye. It is convenient and quick to inspect the interior of various machines, equipment, and assembled objects without disassembly or destruction of assembly. Carry out effective quality management, even in research and development, manufacturing and other fields.
At present, some industrial stations on large-scale automobile manufacturers, engine manufacturers, transmission manufacturers and other production lines are equipped with industrial endoscopes to check the internal inertia of castings and casings, such as whether there are blisters, whether there are quality defects, etc. Check the quality of the assembly inside the product, such as whether it is assembled in place, with or without assembly defects: This greatly improves the control of product quality and ensures the production of quality products. Some auto repair shops are also equipped with industrial endoscopes, which take pictures of damages inside and outside the parts of the user's vehicle, and take pictures with the endoscope. After the repair, photos are taken and stored in the computer. The user can check the comparison before and after the repair at any time, avoiding many unclear problems caused by the fact that the internal parts of the repair parts are not seen.
When the automobile engine fails, the original diagnosis method is to judge whether the cylinder has a problem by experience and listening sound, but in which cylinder, it is necessary to dismantle to determine, and use the endoscope, through the spark plug hole or the nozzle hole, You can directly observe various faults inside the cylinder, such as carbon deposits, strains, cracks, foreign objects, and so on. At the same time, it can also be used for the detection and diagnosis of water tanks, fuel tanks and gear boxes, which improves the diagnostic accuracy and work efficiency, reduces the repair costs, and avoids the damage caused by the multiple disassembly and assembly of the parts.
Equipped with endoscopes in various engines, burners and other equipment, it can directly detect the image of the combustion flame in the equipment to judge the flame combustion condition, thus ensuring stable combustion and safe and economical operation.
In addition, police video endoscopes are widely used in the fields of reconnaissance, security inspection, detonation, anti-smuggling, search and rescue, etc., providing reliable technical means for obtaining intelligence within the crime scene in all-round concealment; in archaeology, endoscopes are available. Inspect the interior of ancient tombs, ancient buildings, etc.
In short, endoscopes have been used in various fields, and they have been gradually intensive. The industrial endoscope (the complete set of instruments) consists of an endoscope, a control box, a light source box, a monitor, and an instrument stand with a roller.
There are two types of industrial endoscopes in use today: (1) Optical fiberscopes. It is a new type of non-destructive testing instrument that combines optical, precision machinery and electronic technology with modern optical fiber technology. It utilizes the characteristics that the optical fiber can still normally transmit and transmit light when bent, and can be used to directly observe the internal defects of the equipment (such as an engine, etc.) or to inspect the cracks and corrosion of the inner wall of the closed cavity without disintegration. It is also possible to find out whether there are any debris and small parts falling off inside, so as to solve the problem that the human eye or other detecting instruments cannot enter the inside of the device and visually observe the internal defects of the device.
The endoscope transmits images through glass fibers, has the advantage of being unaffected by electrical clutter, and is relatively inexpensive; however, since the optical fiber bundle composed of a plurality of optical fibers transmits light, each optical fiber is between Without light, there is black grain, and the black fiber pattern that cannot be removed is formed on the image transmitted by the entire fiber bundle, just like looking at the image through the gauze.
(2) Video (electronic) endoscopes. The micro-CCD device converts the imaging of the object by the optical objective into an electrical signal, and then transmits it to the controller of the video endoscope, and the controller processes the output video signal to the monitor to display a new high-tech non-destructive testing instrument for detecting the image. Compared with the optical fiber industrial endoscope, in addition to the soft and bendable performance, it also has the advantages of high resolution, clear image, vivid color, accurate shape of the detected part, and long effective detection distance. Fine occasions. After the electronic endoscope is added to the computer image processing system, the image can be frozen, stored, cursor positioned, the size of the calculation defect and the subtitle synthesis processing, and the image and the data can be permanently recorded.
Shanghai Caikang Optical Industrial Endoscopy Research Center has developed and produced various industrial endoscopes such as SCK type, PCK type and VCK type for the actual situation of automobile manufacturing, automobile maintenance and repair, aircraft maintenance and other fields.
Its main features are as follows:
(1) Professional-grade high-resolution images;
(2) The true color reproduction of scientific research level;
(3) The digital zoom function of the fiber;
(4) Intuitive image split screen display comparison function;
(5) Complete image digital storage management system;
(6) A variety of probe objective adapters are available for selection.
