[0002] Online 2D inspection equipment is a device that measures 2D size, shape, position and other parameters in real time during a production line or manufacturing process. This type of equipment is usually combined with an automated production line to improve production efficiency, ensure product quality, and reduce the error rate of manual inspection. Online 2D inspection equipment includes a variety of specific equipment types, such as robot vision systems, image measuring instruments, 2D laser scanners and coordinate measuring instruments. Among them, 2D laser scanners use laser beams to scan objects and receive reflected light through receivers to calculate the position and shape of the object's surface. They are often used to measure complex shapes and curved surfaces.

[0003] A known Chinese public authorized invention (publication number: CN110702011A) discloses a two-dimensional laser scanner, which transports the workpiece through a transmission mechanism, drives the screw to rotate through the cooperation of a driving motor, a first bevel gear, and a second bevel gear, and under the cooperation of a connecting block and a screw nut, the screw drives the connecting block to translate through the screw nut, thereby making the two-dimensional laser scanner move stably to scan the workpiece;
