Industrial endoscopes generally come with a light source, the use of optical lenses or camera chips and other components to achieve the detection of image transfer, and ultimately achieve the purpose of observing and detecting defects in the internal structure or internal surface of the inspected equipment. This inspection technology changes the direction and distance of vision of the human eye, expands the observation range, and is mainly used for quality control in the production stage and defect detection and troubleshooting in the operation and maintenance stage, featuring intuitive and efficient, simple and easy to use. The following is the use of Weylin's industrial endoscope scene diagram, the inspector holds the handheld in one hand and sends the probe into the inside of the inspected equipment with the other hand, and you can see the inspection image of the place where the probe is on the screen of the handheld.
Industrial endoscopy detection, involving a variety of technologies, cooperate with each other, in order to achieve efficient detection from orientation to quantitative:
Imaging technology. Clear imaging is the core of visual inspection, different kinds of equipment using different imaging technology and image guide technology, for example: straight rod endoscope through a set of optical lenses placed in the metal rod to conduct optical images, fiber-optic endoscope through the fiber optic bundle to conduct the image, the industrial video endoscope through the probe front end of the CCD (or CMOS chip) for detecting the image of the photoelectric changes, and through the signal cable to the signal cable transmission to the handheld machine screen display. Handheld machine screen display. For the most widely used industrial video endoscopes, the number of native CCD pixels is the core indicator.
Illumination technology. Bright illumination is one of the guarantees of clear imaging, there are front lighting and rear lighting technology, rear lighting will be placed in the probe host or handheld at the back end, relying on fiber optic light conduction to the front of the probe, often high power, high brightness, but the cost is a little high; front lighting is used in the front of the probe to integrate the micro-LED beads in a way that the design is more simple, low-cost, but lighting The front illumination uses micro LED beads integrated in front of the probe, which is simpler in design and lower in cost, but the illumination is often not high enough, and open space detection is a challenge.
Measurement technology. Defect measurement is one of the most important technologies for industrial endoscopy to develop from purely qualitative observation to quantitative analysis. By measuring the length, area, depth and other dimensions of cracks, corrosion and other defects, as well as comparing them to historical data, we can more accurately study the current status of defects and the development trend, and correctly formulate the decision to monitor, or shut down for maintenance, aiming to more economically safeguard the safety of assets. In addition to the traditional double objective lens stereo measurement technology, now more advanced is a single objective lens phase scanning three-dimensional stereo measurement technology.
All-in-one integration technology. The enhancement of security requirements, means that the detection of heavy tasks, the traditional split detection equipment, for the transportation of out to carry, as well as on-site inspection is a relatively heavy burden, lightweight and portable integration of equipment is the trend. Highly integrated module design, lighter and more robust materials, brighter display, ergonomically designed handheld, long standby time of the lithium battery ...... The newest addition to the lineup is a new, more compact design that allows for a more efficient, more reliable, and more convenient way to test and monitor the performance of your device.
