Description

Technical Field

[0001] The utility model relates to the technical field of laser scanning detection devices, in particular to a three-dimensional laser scanning detection device. Background Art

[0002] 3D laser scanning technology is a new technology that has emerged in recent years and has attracted more and more attention in the research field in China. It uses the principle of laser ranging to record the 3D coordinates, reflectivity, texture and other information of a large number of densely packed points on the surface of the measured object. It can quickly reconstruct the 3D model and various drawing data such as lines, surfaces and volumes of the measured target. Since the 3D laser scanning system can densely acquire a large number of data points of the target object, compared with traditional single-point measurement, 3D laser scanning technology is also called a revolutionary technological breakthrough from single-point measurement to surface measurement.

[0003] The existing detection device is relatively complicated to operate when in use, and is slow and inefficient when performing detection.

[0004] The existing patent (Announcement No.: CN215177582U) discloses a three-dimensional laser scanning detection device, which uses a half-gear meshing transmission driven gear to make the worm rotate and stay still periodically, and the worm meshes with the worm wheel to drive the intermediate shaft to drive the bearing plate to deflect periodically by a certain angle, thereby completing the shallow groove station switching, facilitating continuous detection of the workpiece and improving the detection efficiency; through the half-gear meshing transmission rack, the reciprocating frame is raised and lowered along the guide groove, and the detection cover covers the outside of the workpiece when the reciprocating frame descends, and the height of the laser scanner changes accordingly, and the bevel gear meshes with the bevel gear ring to drive the vertical shaft to rotate. The laser scanner can perform a comprehensive multi-directional scan of the workpiece, and the scanned data is transmitted to the industrial computer for comparison with the pre-stored standard data, and the detection results are displayed on the display, which is convenient and practical.

[0005] However, the above technical solution still has certain defects. When the detection device is used, it is necessary to first start the first motor, which drives the half gear to rotate, and the half gear drives the transmission rack to move, and the reciprocating frame drives the detection cover to move up and down, so as to detect the workpiece through the laser scanner. However, the device is relatively cumbersome to operate, so the detection efficiency is low when used, and it is not convenient to use. Therefore, a detection device based on three-dimensional laser scanning is proposed. Utility Model Content
