The electronic industry endoscope is a non-destructive testing tool introduced for industrial inspection and maintenance. ^{[1] The} electronic camera displays the video camera to detect places that cannot be directly observed by the naked eye. It can perform visual qualitative inspection and internal defect inspection of objects. Inspection work such as quantitative measurement. Capturing clear and bright images, super performance and absolute portability are perfectly united, and the latest computer digital storage processing technology is integrated, becoming an indispensable important tool in the field of inspection to solve quality and safety issues.

The electronic industry endoscope can inspect the toxic, harmful and space-constrained parts that are not reachable by people, and it can easily and effectively corrode the internal objects, cracks, welding conditions, foreign objects in complex pipelines, internal processing conditions of casting workpieces, and work wear of parts. Carry out a detailed and comprehensive inspection in such cases.

1.Real-time video inspection of the parts that need to be inspected;

2.Real-time recording of work site images and videos, and can be stored in a database;

3.Real-time image and audio analysis of the collected video information;

4.Real-time wireless transmission of work site images and voice information within the short-distance network;

5.Real-time job site positioning;

Endoscopy applications

Endoscopes are used in automotive parts casting, hydraulic casting, pump body valve casting, mechanical parts casting, pipeline and pipe casting casting units to check the quality of sand casting, burrs, and staggered holes. Endoscopy technology requires compactness and flexibility in the mechanical casting industry. For the parts that need to be inspected are relatively small holes, this requires that the endoscope must be smaller and more flexible and easy to insert; the video display is more intuitive and clear. China and Gaza, glitches and other conditions are clear at a glance.

1. Intraluminal examination. Inspect defects such as surface cracks, peeling, pulling lines, scratches, pits, bumps, spots, corrosion, etc.

2. Inspection of weld surface defects. Check the welding quality such as cracks, incomplete penetration and leaks on the surface of the weld.

3. Assembly inspection. When required and required, use an endoscope to check the quality of assembly; after assembly or a certain process is completed, check whether the assembly position of each component meets the requirements of drawings or technical conditions; whether there are assembly defects.

4. Status check. After certain products (such as worm pumps, engines, etc.) work, endoscopic inspections are performed according to the items specified in the technical requirements.

5. Excess check. Check for residual debris, foreign matter, etc. in the product cavity.

Endoscopy

After the reform and development, due to the development of the economy and the rapid development of China's industry, all industries need data confidence and accuracy to test the conclusions. Therefore, the measurement technology is also developing rapidly. In the process of scientific experiments and production practices, in order to obtain Quantitative information characterizing the characteristics of the research object must be accurately measured.

In addition, there are several other restrictive reasons for the guarantee of test results, including inspectors, endoscopic equipment, inspection objects, and working environment. Among them, the most critical of the testing equipment room, the endoscopic inspection technology plays a greater role.

1. Inspectors should have appropriate eyesight, and be trained and certified in accordance with the standards to which the work is performed. The inspector should be able to operate the endoscope equipment proficiently and select appropriate instruments, tools and methods; be familiar with the provisions of relevant sections such as maintenance and non-destructive testing manuals and other relevant technical documents; be familiar with the internal structure of the engine; be familiar with the types and characteristics of defects; Ability to accurately assess defects.

2. Errors in measurement results are caused by systematic and random errors. System errors are caused by measuring instruments and methods and cannot be completely eliminated, but they can be minimized by reasonable measures. First, choose a high-precision endoscope measurement system, and try to adopt a measurement mode with less error. In specific operations, the best observation position should be obtained as much as possible. The clearer the image and the larger the magnification, the smaller the system error. To ensure that the magnification is in a state that meets the measurement requirements, the alarm for image magnification is displayed in the shadow and stereo measurement system. It can remind the operator that when the INDEX value is less than 5, the measured measurement image cannot guarantee the measurement accuracy and needs to be taken again. This method is very effective to avoid errors caused by human error.

3. The inspection object should comprehensively consider the factors of the inspection object and select appropriate equipment and methods. Therefore, to a certain extent, the accuracy of the test results is determined by the endoscope inspection tool in a large extent, so it is necessary to choose a precise endoscope as a measurement tool.

4. The performance and condition of the endoscope equipment determine its inspection capabilities and effects. The endoscope equipment should be in good working condition, and the measurement system should perform error checking according to the method and time specified in the operation manual. For a long time, endoscopes are mainly used for observation, so when choosing an endoscope, they are accustomed to choose an endoscope with a small diameter, portable and lightweight, strong interchangeability, and clear imaging. With the computer technology, Development, combining endoscope and computer, the new endoscope imaging display system with storage, measurement functions, low maintenance costs and other characteristics.

5. The working environment should be as convenient, comfortable and non-fatiguing as possible for the inspectors, and meet the requirements of the instrument operating manual for the instrument's working environment to prevent misjudgment of inspection results or damage to the instrument due to fatigue or environmental factors. For measurement systems, measurement errors must also be considered.

6. Endoscopy is a visual inspection method (RVI) in non-destructive testing, which is used to inspect areas that cannot be directly accessed by the naked eye with the help of a special photoelectric device (TC8000-Audio Video Recorder Industrial Endoscope). Combining TC virtual endoscope and stereo endoscope technology, after considering the principle of binocular imaging of the human eye, the new stereo 3D endoscope and dual-lens stereo measurement technology can enlarge the image as much as possible without ensuring the image is deformed Therefore, high requirements are imposed on the image display and processing of the endoscope.

Unlike traditional optical or comparative processing techniques, endoscope detection technology, in general, in order to have accurate data and accurate detection results, endoscope is an essential device, endoscope measurement technology The continuous improvement of measurement and measurement accuracy can help inspectors to work for a long time in a safe and comfortable situation, and can save some unnecessary expenses. Therefore, experimenters, inspectors and scientific and technical workers should understand and master , Can reduce errors and make measurement results more accurate.
