Although the industrial endoscope itself is powerful, if it cannot be used correctly when actually performing inspection tasks, it will affect the accuracy of the endoscope inspection results and even fail to complete the inspection task successfully. In order to avoid this situation from happening, we take you to understand several major factors that affect industrial endoscope inspection.
1. Selection of endoscope
There are many types of industrial endoscopes, and different types of endoscopes have different application ranges. Correct selection is the first condition for successfully completing the inspection.
When selecting, you must not only consider the complexity of the use environment, such as whether waterproofing, corrosion resistance, wear resistance, etc. are required, but also determine the type of industrial endoscope to be used based on the condition of the detection object. For example, when the detection path is a straight-through When detecting the path, you can choose a straight rod scope. When the detection path is curved, you can choose a fiber scope or an industrial video endoscope. However, if you require clear imaging at the same time, you can choose the latter.
2. Adjust the probe position and angle
Practice has proved that in order to obtain good image quality, the industrial endoscope probe is often required to be as close as possible to the observation point, for example, within a range of 5 to 25 mm from the detection area.
In addition, the angle between the probe and the plane of the observation object will also affect the detection effect. Usually, the ideal detection effect can be obtained within the range of 45゜~90゜. In actual work, the best detection effect within the above range can be found by adjusting the probe attitude. Angle position to obtain the best detection effect.
3. Good lighting conditions
Endoscope inspection is usually applied in areas that are difficult for inspection personnel to enter or cannot be directly observed with the human eye. These areas are usually narrow or have curved paths and poor light conditions. Therefore, most industrial endoscopes have their own light source for illumination.
Under normal conditions, the color temperature of the illumination source detected by the endoscope is not less than 5600K, and the illumination intensity is not less than 2600lm. Of course, appropriate adjustments can also be made depending on the model of industrial endoscope used.
4. Consider reflectivity factors
Different object surfaces have different reflectivities, which are not only related to the material of the object, but also to the roughness of the object surface.
Therefore, when using industrial endoscopes for inspection, the intensity of endoscope illumination should be selected or adjusted according to the specific conditions of the surface of the object being inspected, so that the image is as clear as possible without affecting the detection effect due to strong reflections and other reasons.
