Industrial endoscope is a portable tool for non-destructive testing, capable of entering areas that are difficult to reach or have low visibility, and revealing secrets hidden in the depths of the machine through videotaping and observation. Here we will introduce the composition and principle of industrial endoscope in detail.
First, the composition of industrial borescopeIndustrial borescope is usually composed of the following main parts:
Lens: the lens is the core component of the borescope, responsible for collecting the image information inside the inspected items. According to different application requirements, different lenses can be selected.
Insertion tube: the insertion tube is the cable part connecting the probe and the controller, and there are video signal cables, guiding wires, and light-guiding optical fibers running through it.
Light source: The light source is responsible for providing enough light to illuminate the interior of the item being detected, and common light sources include LEDs and xenon lamps.
Controller: The controller is usually a handheld device used to control the direction of operation and magnification of the endoscope.
Monitor: the monitor displays the images captured by the endoscope for easy observation and diagnosis by the operator.
In addition, depending on different types of industrial endoscopes, other components such as lens changing devices, guiding devices, measuring devices, and so on, may also be included. The combination of these components enables the industrial endoscope to adapt to different inspection needs and application scenarios.
Second, the working principle of the industrial endoscopeThe working principle of the industrial endoscope is mainly the use of optical imaging principle, through the camera to capture the internal image of the need to detect, and through the cable to transmit the image to the handheld machine for processing and display. Specifically, the workflow of the industrial endoscope is as follows:
Probe contact with the detected object: the probe of the industrial endoscope is the part that directly contacts the detected object, and it is equipped with a camera and a light source inside.
Image signal transmission: the image signal captured by the camera is transmitted to the inside of the handheld through the wire.
Image Processing and Display: After receiving the image signal, the handheld performs image processing and display. The user can observe the internal condition of the detected object through the operation interface of the handheld.
Controller control of probe movement: through the controller, the user can control the probe of the industrial endoscope to move, rotate, zoom and so on, in order to observe different parts of the inspected object.
Power supply: industrial endoscopes need power supply, which is usually provided by batteries or AC power.
Third, the application of industrial endoscopesIndustrial endoscopes are widely used in aerospace, automobile manufacturing, machinery and equipment and many other fields for product quality inspection, fault diagnosis and maintenance. It can carry out non-destructive testing on the inside of the equipment, discover potential faults and problems, improve the safety and stability of the equipment, and also provide an accurate basis and positioning for equipment maintenance.
Fourth, the use of industrial endoscopy precautionsBefore using the industrial endoscope, you must first familiarize yourself with the operation manual and operate in accordance with the requirements of the regulations. Before use should understand the performance of the instrument, to avoid the use of non-compliant power supply and connection line.
When detecting, put the lens of the industrial endoscope vertically or tilted against the object to be detected, and slowly rotate the lens until the image is clear. During the inspection process, hold and place the industrial endoscope gently to avoid damaging the instrument and the object being inspected.
Adjust the focal length and image size of the borescope to better observe the inside of the inspected object. When adjusting the focal length, turn the focusing handwheel slowly to avoid rapid adjustment that may cause image distortion.
When using the industrial endoscope, be careful not to bend or weigh the optical fiber at a sharp angle, so as not to cause internal breakage of the optical fiber or image distortion. At the same time, avoid observing high temperature objects with the industrial borescope, so as not to burn the instrument or the object to be inspected.
Don't put the industrial borescope in water or expose it to rain, so as not to damage the internal electronic components of the instrument. Put the industrial endoscope back to its original position after use, and carry out maintenance and repair according to the provisions of the operation manual.
When using the industrial borescope, it is necessary to avoid damaging the inspected object or causing other losses. You should know the nature, shape and size of the object to be inspected and other information before the inspection, and choose a suitable industrial endoscope for the inspection.
