[0021] like Figure 1-3As shown, this utility model embodiment provides a fully automatic fiber optic end-face inspection device, including a motion platform 100 and an inspection module 200. The inspection module 200 is fixedly connected to the motion platform 100. The inspection module 200 consists of a microscope objective 201, an objective lifting electric Z-axis 202, a laser autofocus 203, a microscope tube 204, a camera rotary stage 205, a rotary stage motor 206, a visual inspection camera 207, a rotating drag chain 208, and an inspection light source 209 to perform the microscopic inspection function of the fiber optic connector end face of the product. The positioning function of the inspected product is completed by a large field of view scanning camera 210, a coaxial light source 211, and a large field of view scanning microscope tube 212. The microscope objective 201 is fixedly connected to the lifting plate of the objective lifting electric Z-axis 202. The objective lifting electric Z-axis 202, the laser autofocus 203, the camera rotary stage 205, the rotary stage motor 206, and the rotating drag chain 207 complete the microscopic inspection function of the fiber optic connector end face of the product. The drag chain 208, detection light source 209, and large field of view scanning tube 212 are fixedly connected to the microscope tube 204. The visual inspection camera 207 is fixedly connected to the camera rotating stage 205.

Then, the X, Y, and Z motion axes 101 move the coordinates to enable the large field-of-view scanning camera 210, coaxial light source 211, and large field-of-view scanning microscope tube 212 to complete the product positioning. After the product positioning is completed, the microscope objective 201, objective lifting electric Z-axis 202, laser autofocus 203, microscope tube 204, camera rotary stage 205, rotary stage motor 206, visual inspection camera 207, rotating cable chain 208, and inspection light source 209 combine to complete the microscopic inspection of the fiber optic connector end face of the product.
