Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric measuring instruments, in particular to a lens protection structure and a photoelectric measuring instrument. Background Art

[0002] With the development of science and technology, the application of intelligent robots based on PLC control is becoming more and more widespread. In the production fields such as automobiles, spraying robots have basically replaced manual paint spraying operations, greatly improving work efficiency and spraying quality, and reducing the chance of workers being exposed to harmful substances in paint, ensuring the health of workers.

[0003] Chinese patent CN213287411U discloses a robot laser rangefinder lens protection device, which prevents the laser rangefinder lens from being dirty due to paint mist and dust during spraying, ensures the working performance of the laser rangefinder, reduces the probability of cleaning the lens, and increases the service life of the laser rangefinder.

[0004] However, the above solution does not take into account the internal environment of the lens when it is stored. When the lens is opened, dust will enter the interior and the lens will still be contaminated by dust. At the same time, repeatedly pushing and pulling the lens will easily cause the direction and position of the lens to change each time, thereby affecting the detection accuracy. Its structure solves some problems, but it still does not fundamentally solve the problem of dust accumulation in the laser rangefinder lens. Utility Model Content
