Technical Field

[0001] This application relates to the technical field of prism detection, and more particularly to an optical prism production inspection platform. Background Art

[0002] Optical prisms are used in optical devices to refract or reflect light sources, changing the propagation direction and path of light. Therefore, optical monitoring is required during the production of optical prisms.

[0003] In this regard, Chinese Patent Application No. CN201821982400.7 discloses a production inspection table for an optical prism roller. This solution mainly sets a detection auxiliary fixing frame with a slide rail and symmetrically arranged optical prism roller placement brackets on the main frame. Different detection devices can be installed on the detection auxiliary fixing frame to observe the surface of the optical prism roller. The symmetrically arranged optical prism roller placement brackets can rotate back and forth to detect the entire surface of the optical prism roller.

[0004] However, during the implementation of the technical solution in the embodiments of this application by the inventor of this application, it is found that the above technology has at least the following technical problems:

[0005] The outer surface of the optical prism is a polyhedron and cannot roll stably on the roller, resulting in an uncertain reflection angle, so the detection data is not accurate enough. Summary of the Utility Model

[0006] To make up for the above deficiencies, this application provides an optical prism production inspection platform, aiming to improve the problems mentioned in the above background art.

[0007] An embodiment of this application provides an optical prism production inspection platform, including a bracket and a clamping member. A rotating ring is rotatably connected to the clamping member. A prism body is clamped between the two rotating rings. Index holes are circularly arranged on the rotating ring. A pinning member is arranged on the bracket and pinned to the corresponding index holes. A light source is translated on the bracket.

[0008] In a specific implementation, the clamping member includes a top rod and a cylinder. The top rod is rotatably connected to one end of the bracket, and the cylinder is installed at the other end of the bracket.

[0011] In the above implementation process, the positioning block is used to position the clamping angle of the prism body. By moving the positioning block on the scale plate, the prism bodies of different sizes can be positioned, so that the geometric center of the cross-section of the prism body coincides with the rotation axis of the swivel as much as possible. In this embodiment, the upper surface of the positioning block is also provided with scales to facilitate the accurate placement of the prism body on the positioning block.

[0012] In a specific implementation, the positioning block is slidably connected to the scale plate, and a screw is screwed on the positioning block, and the screw abuts against the scale plate.

[0013] In the above implementation process, after adjusting the positioning block, it can be fixed tightly by using the screw.

[0014] In a specific implementation, the scale plate is provided with grooves corresponding to the scales, and the positioning block is provided with protrusions.

[0015] In the above implementation process, by using the protrusions to fit into the grooves, when the positioning block is fixed at the corresponding scale, accurate positioning can be achieved, which is also beneficial to the same positions of the positioning blocks at both ends of the bracket.

[0016] In a specific implementation, the plug member includes a pin rod, the pin rod is slidably connected to the bracket, and a spring is provided between the pin rod and the bracket.

[0017] In the above implementation process, the angle of the prism body is positioned by inserting the pin rod into the corresponding indexing hole.

[0019] In the above implementation process, the pull ring is convenient for pulling the pin rod.

[0020] In a specific implementation, the light source is a laser emitter, a slide rail is provided on the bracket, and the laser emitter is installed on the slide rail.

[0021] In the above implementation process, the laser emitter can slide accurately and smoothly along the slide rail, so as to emit light along the axial direction of the prism body.

[0022] Compared with the prior art, the beneficial effects of this application are: the prism body is clamped by the clamping member, the prism body is rotated by the swivel, and the plug member is pin-connected with the indexing hole on the swivel to accurately fix the prism body at a specified angle, so that the light source can accurately irradiate the prism body to obtain accurate detection data.

[0030] Please refer to Figures 1 - 3 , the clamping member 20 includes an ejector rod 21 and a cylinder 22. The ejector rod 21 is rotatably connected to one end of the bracket 10, and the cylinder 22 is installed at the other end of the bracket 10. The ejector rod 21 is used to position one end of the prism body 40, and the cylinder 22 is used to adapt to prism bodies 40 of different lengths.

[0031] Please refer to Figures 1 - 3, the clamping member 20 further includes a graduated scale plate 23. A graduated scale plate 23 is rotatably connected to each of the telescopic ends of the ejector rod 21 and the cylinder 22. A positioning block 24 is provided on the graduated scale plate 23. The positioning block 24 is used to position the clamping angle of the prism body 40. By moving the positioning block 24 on the graduated scale plate 23, prisms bodies 40 of different sizes can be positioned, so that the geometric center of the cross-section of the prism body 40 coincides with the rotation axis of the swivel ring 30 as much as possible. In this embodiment, the upper surface of the positioning block 24 is also provided with graduations to facilitate the accurate placement of the prism body 40 on the positioning block 24.

[0032] Please refer to Figures 1 - 3 , the positioning block 24 is slidably connected to the graduated scale plate 23. A screw 25 is screwed onto the positioning block 24, and the screw 25 abuts against the graduated scale plate 23. After adjusting the positioning block 24, it can be fixed tightly by using the screw 25.

[0033] Please refer to Figures 1 - 3 , grooves corresponding to the graduations are provided on the graduated scale plate 23, and protrusions are provided on the positioning block 24. By fitting the protrusions into the grooves, when the positioning block 24 is fixed at the corresponding graduation, accurate positioning can be achieved, which is also beneficial to the same positions of the positioning blocks 24 at both ends of the bracket 10.

[0034] Please refer to Figures 1 - 3 , the plug-in member 50 includes a pin rod 51.

Adjust the two positioning blocks 24 to the specified positions and tighten and fix them with screws 25. Then place both ends of the prism body 40 on the two positioning blocks 24, and then the air cylinder 22 ejects to clamp and fix the prism body 40. Rotate the rotating ring 30 to the specified angle and insert the pin rod 51 into the corresponding indexing hole to position the angle of the prism body 40. Then the laser emitter emits laser light, which is refracted or reflected by the prism body 40 onto the peripheral projection screen. By axially moving the laser emitter on the slide rail 70, the entire prism body 40 can be irradiated. Then, through refraction or reflection, a linear light spot is left on the projection screen, which can be compared with the scale line on the projection screen. In another embodiment, the projection screen is replaced by a photosensor and converted into an electrical signal for analysis and comparison by the monitoring software. The rotating ring 30 is also convenient for manual rotation. In summary, the prism body 40 is clamped by the clamping member 20, the prism body 40 is rotated by the rotating ring 30, and the prism body 40 is accurately fixed at the specified angle by pin-connecting the pin member 50 with the indexing hole on the rotating ring 30, so that the light source 60 can accurately irradiate the prism body 40 to obtain accurate detection data.
