[0002] By gluing two right-angle prisms together, we can form a Figure 1 The right prism shown in the figure. After the right-angle prism is glued together, it is necessary to inspect the prism for the following reasons:

[0003] If the horizontal and vertical optical axes of the two right-angle prisms are not perpendicular to each other, image tilt will occur. Furthermore, if the working surfaces of the two right-angle prisms are not parallel to each other, an angle will appear between the incident and outgoing light rays, resulting in an optical axis non-parallel error. Therefore, after the right-angle prisms are glued together, the prisms must be tested for image tilt and optical axis parallelism.

[0024] During implementation, the prism camera 200 and the autocollimation front mirror 400 are first calibrated so that the crosses of the two coincide, and then the glued prism is placed on the clamping station of the loading platform 300. The positional relationship between the cross of the prism camera 200 and the cross of the autocollimation front mirror 400 can be used to determine whether the image tilt of the prism meets the requirements. At the same time, the center of the reflection cross of the glued prism is adjusted to be aligned with the center of the division cross of the autocollimation front mirror. At this time, multiple reflected images can be seen in the eyepiece camera 520. The optical axis parallelism error can be obtained by reading the distance grid value between the reflected images, thereby completing the detection process.

[0025] In this embodiment, there are two prism cameras 200, which are arranged in sequence along a direction perpendicular to the line connecting the loading platform 300 and the autocollimation front mirror 400. The two prism cameras 200 are respectively arranged facing the two right-angle prisms on the loading platform 300.

[0026] The prism camera 200 in this embodiment is a CCD camera with a built-in high-definition lens.

[0027] like Figure 3 As shown, the loading platform 300 in this embodiment includes an adjustment platform 310 and a prism carrier. The bottom of the adjustment platform 310 is movably connected to the base 100, and the top of the adjustment platform 310 is connected to the prism carrier. Two clamping stations are formed on the top of the prism carrier.

[0028] In one embodiment, the bottom of the adjustment platform 310 is rotatably connected to the base 100. The adjustment platform 310 can be connected to the base 100 via a rotating shaft and driven to rotate by a motor. Of course, the adjustment platform 310 can also be driven to rotate manually or by other means to adjust the circumferential position of the prism.

[0029] In one embodiment, one of the engaging stations includes a first engaging slot 320 formed on the prism carrier, wherein a right-angle prism is horizontally placed in the first engaging slot 320, and the other engaging station includes a second engaging slot 330 formed on the prism carrier, wherein another right-angle prism is vertically placed in the first engaging slot 320. The loading platform 300 further includes a first movable member and a second movable member disposed on the prism carrier, the first movable member and the second movable member being slidably connected to the prism carrier, the first engaging slot 320 being formed on the first movable member, and the second engaging slot 330 being formed on the second movable member.

[0030] It can be understood that the first movable member and the second movable member both include an X-axis movable slide and a Y-axis movable slide, the bottom of the X-axis movable slide is slidably connected to the prism carrier, the bottom of the Y-axis movable slide is slidably connected to the X-axis movable slide, and the sliding directions of the X-axis movable slide and the Y-axis movable slide are arranged perpendicular to each other along the horizontal direction.

[0031] Through the above-mentioned arrangement, the detection device can be applied not only to the detection of prisms after gluing, but also to the gluing of prisms. Specifically, the two right-angle prisms are placed in the first card slot 320 and the second card slot 330 respectively, and glue is applied to the pre-connected parts of the two right-angle prisms. By adjusting the positions of the two right-angle prisms, when they are moved to a position where the image tilt detection and optical axis parallelism difference detection results meet the requirements, the relative position of the two right-angle prisms when glued is obtained.

[0032] During the above bonding process, the cross images of the prism camera 200 and the autocollimation front mirror 400 are as follows: Figure 5 In the case shown in FIG, at this time, by adjusting the positions of the two right-angle prisms, the cross image 400 of the prism camera 200 and the self-collimating front mirror are overlapped, as shown in FIG. Figure 4 As shown in , it shows that the image tilt of the prism meets the requirements.

[0033] like Figure 2 As shown, in this embodiment, the optical axis parallelism error detection component 500 includes a relay lens 510, an eyepiece camera 520 and a light source 530. The autocollimating front mirror 400, the relay lens 510 and the eyepiece camera 520 are connected in sequence, and the light source 530 is installed in the relay lens 510.

[0034] In one embodiment, a display screen 600 is further included, and the display screen 600 is electrically connected to the prism camera 200 and the eyepiece camera 520 .

[0035] There are two display screens 600 , one of which is electrically connected to the prism camera 200 , and the other is electrically connected to the eyepiece camera 520 .

[0036] Compared with the existing technology: first calibrate the prism camera 200 and the autocollimation front mirror 400 so that the crosses of the two coincide, and then place the glued prism on the clamping station of the loading platform 300. The positional relationship between the cross of the prism camera 200 and the cross of the autocollimation front mirror 400 can be used to determine whether the image tilt of the prism meets the requirements. At the same time, adjust the center of the reflection cross of the glued prism to align with the center of the division cross of the autocollimation front mirror. At this time, multiple reflected images can be seen in the eyepiece camera 520. By reading the distance grid value between the reflected images, the optical axis parallelism error can be obtained, thereby completing the detection process.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
