Description

Technical Field

[0001] The present invention relates to the technical field related to sensor assembly, and specifically to a 3D line spectral profile scanning sensor that is convenient for assembly and fixation. Background Art

[0002] The line structured light technology based on the triangulation method has the advantages of simple model, no light stripe confusion, and easy implementation. It is widely used in the detection of parts on conveyor belts, the measurement of specific profiles of the surfaces of measured objects, etc. Using the line structured light method, a high-contrast light stripe is projected in the measured area, and a area array CCD camera is used to receive the scattered light, so as to obtain the cross-sectional shape or profile of the illuminated area on the surface. Therefore, the sensor implemented with the line structured light technology is called a profile sensor.

[0003] The profile sensor can scan the defects and surface profiles of objects more accurately. The problems existing in the prior art are: the profile sensor is light and small and convenient to carry, and its installation is mostly by screw fastening. After frequent disassembly and use, the internal threads are easily damaged and the situation of slipping threads occurs, and the profile sensor cannot be effectively fixed, resulting in the sensor falling and being damaged, which is not convenient for users to use. For this reason, those skilled in the art have proposed a 3D line spectral profile scanning sensor that is convenient for assembly and fixation to solve the problems raised in the above background. Summary of the Invention

[0004] The purpose of the present invention is to provide a 3D line spectral profile scanning sensor that is convenient for assembly and fixation to solve the problems raised in the above background art.

[0028] Embodiment 2: Refer to Figure 1 , Figure 2 , Figure 4 , on the basis of Embodiment 1, a notch 601 is provided in the middle of the mounting column 6. Two pinch plates 603 are symmetrically arranged in the notch 601. The bottom end of the first movable groove is open.

[0030] Working principle: When in use, the base 4 is installed to the top of the sensor body 3 through the adhesive plate 401. The base 4 is relatively thin. When the sensor body 3 is stored in a storage box, etc., there is no need to remove the base 4. When in use, the bottom of the adsorption frame 5 is inserted into the insertion groove 402, and the threaded handle 505 is turned to move the threaded handle 505 upward, thereby driving the piston plate 502 to move upward, thereby increasing the pressure at the bottom of the inner cavity of the adsorption frame 5, so that the bottom of the adsorption frame 5 is tightly sucked on the base 4, and then the two pinching plates 603 are pinched with the thumb and index finger, and the lower palm of the thumb and the other three fingers are used to pinch the installation Install the column 6, install the rear part of the installation column 6 into the first rectangular groove 201, insert the rear end of the pinching plate 603 into the second rectangular groove 202, and embed the embedding block 606 into the embedding groove 203. The rear end corner of the embedding block 606 is rounded to facilitate the press-type installation of the embedding block 606. The two pinching plates 603 are driven away from each other by the elastic member 605, so that the embedding block 606 will not be separated from the embedding groove 203 without external force. When disassembling the installation column 6, pinch the pinching plate 603 by hand to bring the two pinching plates 603 close to each other to remove the installation column 6 from the first rectangular groove 201.
