When an operator needs to check the material more precisely, such as confirming a fine scratch and analyzing a flaw cause, a microscope on the upper side needs to be started and moved to a predetermined observation position of the material. The visual inspection module on the market mainly adopts a vertical camera module. The illumination light source part of the vertical camera module overlaps with a descending path of a microscope lens or an observation position in a physical space, and thus a screw of the whole vertical camera module needs to be manually loosened, and then the whole module needs to be moved on a horizontal plane by a distance to completely leave a space directly below the microscope, so that the adjustment process is relatively complicated. Moreover, the vertical space requirement of the camera module for a machine table is relatively high, and thus the camera module is not suitable for a small machine table or a detection station with a small vertical space. If a horizontal micro visual inspection module with a simple structure, which changes a light path direction by integrating a reflecting mirror to reduce a vertical height and realizes linkage precise positioning by a multi-stage linkage limiting mechanism, can be designed, the above problems can be solved.
