Description

Technical Field

[0001] This invention relates to the field of binocular optical axis parallelism detection technology, specifically to a fully automated laser detection device for the optical axis parallelism of binoculars. Background Technology

[0002] Binoculars are optical instruments consisting of two independent tubes arranged side by side. The objective lens at the front focuses light from distant objects, and after the image is corrected by an internal image-inverting prism, the image is magnified by the eyepiece. The distance between the two tubes can be adjusted to accommodate different users' interpupillary distances. The core of binoculars relies on the parallelism of the optical axes of the two tubes to ensure a clear stereoscopic vision without ghosting. They are widely used in scenarios such as sightseeing, outdoor activities, and astronomical observation. They combine portability and observation comfort, making them a commonly used observation tool that balances practicality and optical performance. In the production of binoculars, in order to ensure the quality of binoculars, a fully automatic laser testing device for the parallelism of the optical axes of binoculars is required.

[0003] The fully automated laser inspection equipment for the optical axis parallelism of binoculars is a specialized device integrating high-precision laser reference generation, intelligent clamping calibration, image acquisition and processing, and closed-loop feedback adjustment. Its core technology involves simulating an infinity target beam with a laser. After transmission through the left and right binocular tubes, the image acquisition device captures reference images such as crosshairs. Combined with template matching and grayscale centroid methods, the coordinates of the optical axis centers of the left and right binocular tubes are located. The device automatically calculates the optical axis parallelism deviation and simultaneously corrects the clamping or laser angle using a five-dimensional adjustment frame and servo motors, eliminating human interpretation errors and achieving rapid, fully automated inspection with sub-arcsecond accuracy. This equipment is well-suited to the efficient verification needs of optical axis parallelism in the mass production of binoculars.

[0004] However, the existing fully automated laser testing equipment for the optical axis parallelism of binoculars has the following shortcomings: Currently, the fully automatic laser testing equipment for the optical axis parallelism of binoculars on the market has significant limitations during testing. Due to the large differences in appearance between various types and brands of binoculars, it is difficult to directly match the optical axis with the testing laser when using only traditional external clamping methods to hold and fix them. This causes the testing laser to deviate from the optical axis of the binoculars from the very beginning, thus affecting the subsequent testing of the binoculars.

[0005] Therefore, we propose a fully automated laser detection device for the optical axis parallelism of binoculars to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a fully automatic laser testing device for the optical axis parallelism of binoculars. This device adopts an internal support clamping and dynamic calibration method. A DC motor drives the internal support slider to achieve multi-directional synchronous internal support, correcting manual adjustment errors to ensure that the eyepiece and laser source are coaxial. A linear motor, in conjunction with a pressure sensor and a rotary stepper motor, automatically fine-tunes the telescope angle to achieve force balance. With the assistance of auxiliary laser monitoring benchmark stability, this completely solves the problem of the difficulty in achieving precise optical axis alignment using traditional external clamping methods. In the testing stage, the device uses a beam-expanding reflection optical path. After the laser beam is expanded by the telescope, it is transmitted over a long distance through multiple mirrors. The optical path extension effect amplifies the optical axis deviation angle, and finally, the beam is focused and projected onto the scale by a concave mirror. This design significantly improves the recognition of minute errors and achieves high-precision optical axis detection.

A spare clamping ring 222 is provided on the inner side of the receiving groove 221. Multiple sliding rods 223 are installed on the outer side of the spare clamping ring 222. A telescopic spring 224 is sleeved on the outer side of the sliding rod 223. The bottom outer side of the sliding rod 223 slides on the bottom of the receiving groove 221. The spare clamping ring 222 slides on the inner side of the receiving groove 221 through the sliding rod 223. An inner support slider 225 is slidably connected to the inner side of the multiple rotating clamping plates 218. The inner support slider 225 is located at the bottom of the slide groove 214. The connecting rod... 213 is installed on the top of the inner support slider 225. Detection rods 227 are slidably connected to the inner sides of multiple detection holes 217. Pressure sensors 228 are installed at one end of each detection rod 227. Mounting brackets 226 are installed on the outer sides of the pressure sensors 228. Vertical plates 232 are installed at the other ends of the detection rods 227. A top strip 231 is installed on the top of the vertical plate 232. Multiple mounting rods 230 are arranged around the bottom of the top strip 231. Two mounting plates 229 are installed at the bottom of the mounting rods 230. The mounting plates 229 are installed on the top of the base 1. A fourth bracket 241 is installed on the top of the base 1.

[0023] The overall effect of Embodiment 1 is as follows: First, adjust the eyepiece spacing of the binoculars to be tested so that it is aligned with the output ends of the detection laser modules 240 on both sides of the device. Then, place the eyepiece ends on the outside of the clamping arc ring 220 and the objective lens end on the inside of the clamping module 203. Turn on the DC motor 209 to drive the threaded rod 210 to rotate. Drive the slide bar 212 to slide in the slide groove 214 through the threaded cylinder 211. The slide bar 212 drives the conical inner support slider 225 to move through the connecting rod 213, forcing the rotating clamping plates 218 around the connecting frame 215 to expand outward, thereby pushing the clamping arc ring 220 to expand outward synchronously. Multiple clamping arc rings 220 form an inner support clamp on the inner side of the eyepiece end, correcting the manual adjustment error and making the inner wall of the eyepiece and the clamping arc ring 220 fit equidistantly. This achieves coaxial alignment between the center of the eyepiece and the center of the clamping arc ring 220, ensuring that the two eyepiece ends correspond precisely to the axis of the detection laser module 240. Then, turn on the linear motor. 205. The clamping arc 220 and the binoculars as a whole are moved backward. The objective lens slides along the bottom inner side of the clamping module 203. At this time, the detection rod 227 slides in the detection hole 217 until the pressure sensor 228 contacts the outer surface of the eyepiece. Since the detection rod 227 is kept horizontal and perpendicular to the vertical plate 232, and the outer surface of the eyepiece is a uniform arc, the pressure values ​​of each pressure sensor 228 should be equal. If the values ​​deviate, the clamping module 203 is activated to fix the objective lens. The pneumatic rotary stepper motor 202 drives the clamping module 203 to fine adjust the telescope angle until the values ​​of each pressure sensor 228 are balanced. During the entire adjustment process, the auxiliary laser module 233 continuously emits laser to the lens end rod 239. After reflection, it is received by the laser displacement sensor 235 and the laser collimation detection module 236 to monitor the status of the protective cylinder 207 and related components in real time, ensuring the stability of the detection benchmark, thereby achieving precise clamping and fixing of the binoculars.

[0024] Example 2, according to Figure 2 - Figure 9As shown, a detection chamber plate 3 is installed on the top of one side of the base 1, a top plate 4 is installed on the top of the detection chamber plate 3, a second reflective mirror 6 is installed at the bottom of the top plate 4, a third reflective mirror 7 is installed on the other side of the bottom of the top plate 4, a concave mirror 8 is installed on the inner side of the detection chamber plate 3, a scale reference plate 9 is provided at the bottom of the concave mirror 8, the scale reference plate 9 is installed on the top of the base 1, a first reflective mirror 5 is installed on the top of the base 1, and the first reflective mirror 5 is located at the bottom of the second reflective mirror 6.

[0025] The overall effect of Embodiment 2 is as follows: During detection, the detection laser module 240 emits a laser. The laser enters through the eyepiece and exits through the objective lens. Due to the optical characteristics of the telescope, the laser beam expands. Since the first reflecting mirror 5 is close to the objective lens, the area of ​​the expanded beam spot is moderate. The beam is reflected sequentially by the first reflecting mirror 5, the second reflecting mirror 6, and the third reflecting mirror 7, and finally shines on the concave mirror 8. The concave mirror 8 refocuses the beam and projects it onto the scale reference plate 9. If the beam emitted from the objective lens is tilted, i.e., the optical axis is deviated, the deviation angle is amplified after the beam is transmitted over a long distance through the multi-faceted reflecting mirrors, which significantly improves the recognition of small errors. The operator can directly complete the detection according to the scale on the scale reference plate 9.

[0026] The working principle of the entire device is as follows: First, adjust the distance between the two eyepieces of the binoculars to be tested so that the two eyepieces are aligned with the output ends of the two detection laser modules 240 of the device. Then, directly place the two eyepiece ends on the outside of the clamping arc ring 220 and the objective lens end inside the clamping module 203. At this time, turn on the DC motor 209, which drives the threaded rod 210 to rotate. Through the threaded relationship between the threaded rod 210 and the threaded cylinder 211, the threaded cylinder 211 drives the slider 212 to slide inside the slide groove 214. This further causes the slider 212 to drive the inner support slider 225 to move through the connecting rod 213. As the inner support slider 225 moves, because it is conical, it... This causes the rotating clamps 218 located around its outer perimeter to open outwards. One end of the rotating clamps 218 rotates outside the connecting frame 215, while the other end drives the clamping arcs 220 to unfold outwards. By opening the clamping arcs 220 in multiple directions, the inner side of the telescope eyepiece is clamped in an inward support manner. This further improves the accuracy of the manual pre-adjustment of the eyepiece spacing. With multiple clamping arcs 220 simultaneously opening outwards and forming an inward support, the inner side of the eyepiece is equidistantly fitted with the multiple clamping arcs 220, ensuring that the center of the eyepiece is coaxially aligned with the center of the component clamping arcs 220. This guarantees that the axes of the two eyepieces correspond to the axes of the two detection laser modules 240. Then, the linear motor 20 is activated. 5. The clamping arc 220 and the binoculars held by the clamping arc 220 move backward together. The objective lens is in a sliding state on the bottom surface of the inner side of the clamping module 203. At this time, the detection rod 227 slides inside the detection hole 217, eventually making the pressure sensor 228 contact the outer surface of the eyepiece inside the eyepiece. Because the multiple detection rods 227 are in a state of absolute perpendicularity to the vertical plate 232, the multiple detection rods 227 are in a horizontal state, and the outer surface of the eyepiece is a uniform arc shape, the distance pushed by the eyepiece to each pressure sensor 228 is equal. Therefore, the values ​​of each pressure sensor 228 should be equal. When the value of one pressure sensor 228 deviates, the clamping module 203 is activated to... The objective lens is clamped, and the clamping module 203 is rotated by the pneumatic rotary stepper motor 202, which in turn rotates the entire binoculars to achieve fine-tuning of the angle. Finally, the angle is adjusted to be equal to the value of the pressure sensor 228. Throughout the entire adjustment process, the auxiliary laser module 233 is always turned on. The detection laser emitted by the module is directed towards the mirror end bar 239, and the mirror end bar 239 refracts the laser. The laser displacement sensor 235 and the laser collimation detection module 236 detect the reflected light, thereby detecting whether there are any problems with the protective cylinder 207 and its components during the entire adjustment process, further ensuring the accuracy of the detection basis, and thus achieving precise clamping and fixing of the binoculars.

[0027] In subsequent testing, a detection laser is emitted by the detection laser module 240. The detection laser enters through the eyepiece and exits through the objective lens. Due to the characteristics of the telescope, the detection laser beam is expanded. The expanded laser beam is reflected by the first reflecting mirror 5, which is relatively close to the objective lens. Because the distance between the first reflecting mirror 5 and the objective lens is short, the expanded laser beam area is moderate. The expanded laser beam is then reflected by the first reflecting mirror 5 to the second reflecting mirror 6, and finally by the second reflecting mirror 6 to the third reflecting mirror 7. Finally, the laser beam is reflected from the third reflecting mirror 7 to the concave mirror 8. The optical characteristics of the concave mirror 8 cause the beam to be refocused and directed onto the scale reference dial 9. At this time, the laser beams on both sides appear on the scale reference dial 9. When the beam emitted from the objective lens is tilted, that is, when the optical axis deviation of the telescope is detected is detected, the beam travels through the first reflecting mirror 5 to the second reflecting mirror 6 and then to the third reflecting mirror 7, extending the beam path. This amplifies the deviation of the beam and increases the recognition of small differences. The beam is then compared with the scale on the scale reference dial 9, thus completing the detection.
