Description

Technical Field

[0001] This invention belongs to the field of lens technology, specifically, it relates to a lens optical inspection device and method for lens processing. Background Technology

[0002] In the field of optical lens processing, lens optical performance testing is a core process to ensure the quality of finished products. The comprehensiveness, accuracy, and protective effect of the testing on the lens directly determine the performance and yield of the final lens product, making it an indispensable key link in the lens processing industry chain.

[0003] However, existing methods for detecting whether lenses are susceptible to scratches often involve placing the lens and having a specialized scratch detection component move across it. After the component moves across the lens, a specific testing device is used to check for scratches. However, the scratch detection component is often affected by small particles such as dust, which can cause these particles to move under pressure and scratch the lens, leading to inaccurate detection results.

The end of the connecting rod 214 away from the installation slider 215 is provided at the bottom of the movable slider 213.

[0025] like Figures 2 to 10 As shown, the threaded sleeve 232 has a circular groove 233 on its side wall, and a sliding block 234 is slidably arranged on the circular groove 233. A multi-stage telescopic rod 235 is provided at one end of the sliding block 234 away from the circular groove 233, and a C-shaped connecting rod 24 is provided at the other end of the multi-stage telescopic rod 235.

[0026] like Figures 2 to 10 As shown, further, the bottom of the circular mounting ring 25 is provided with four movable rods 251 arranged in a circular pattern. Each movable rod 251 moves through the circular mounting cylinder 252 and its port is located on the sealing plug 253.

[0027] Example 2:

[0028] The difference between the above embodiments and this embodiment is that: Figures 2 to 10 As shown, a lens optical inspection device for lens processing includes a moving component including a hydraulic cylinder 31. A Z-shaped connecting rod 3 is provided at the fixed end of the hydraulic cylinder 31, and the other end of the Z-shaped connecting rod 3 is provided on the mounting slider 215. The output end of the hydraulic cylinder 31 is on a mounting plate 311. Placement rods 312 are provided around the mounting plate 311, and the ends of the four placement rods 312 away from the mounting plate 311 are provided on the side wall of the circular mounting cylinder 252.

[0029] like Figures 2 to 11 As shown, in a specific embodiment, a fixed cylinder 32 is provided at the bottom of the mounting plate 311, a sliding plate 321 is provided inside the fixed cylinder 32, a return spring 322 is provided on the sliding plate 321, one end of the return spring 322 away from the sliding plate 321 is provided on the fixed cylinder 32, and a sliding rod 326 is provided at the bottom of the sliding plate 321.

[0030] like Figures 2 to 11 As shown, further, the end of the sliding rod 326 away from the sliding plate 321 is disposed on the circular placement plate 323, and a rotating bearing 324 is disposed at the bottom of the circular placement plate 323, and a detection ball 325 is disposed at the bottom of the rotating bearing 324.

[0031] Example 3:

[0032] This invention also discloses a lens optical inspection method for lens processing, the steps of which are as follows: Step 1: Place the four lenses vertically on the lens placement stage 12, so that the ends of the lenses correspond to the clamping components 121. Control the operation of the clamping components 121 to securely clamp the lenses, providing a stable placement basis for subsequent testing. Step 2: Start the hydraulic cylinder 31, and its output end drives the mounting plate 311 and the fixed cylinder 32 to move downward. At the same time, the circular mounting cylinder 252 moves downward synchronously through the placement rod 312 until the detection ball 325 is in contact with the lens or the lens placement stage 12. Step 3: Start the servo motor 2, drive the rotating rod 21 and the rectangular mounting plate 211 to rotate, so that the mounting slider 215 moves along the trajectory of the vortex groove 221, thereby driving the detection ball 325 to move along the trajectory; at the same time, the threaded sleeve 232 moves down, driving the sealing plug 253 to squeeze the cavity, and the gas is discharged from the air port 254 to remove dust from the lens. Step 4: When the ball bearing 325 moves along the track, it always maintains effective contact with the lens surface with the help of the elastic action of the return spring 322, and performs all-round rolling detection of optical parameters such as the flatness and curvature of the lens surface. Step 5: After the ball bearing 325 is inspected, start the four line scanning cameras 14 to perform optical scanning on the lens, accurately identify whether there are defects such as cracks or chipped edges on the lens, and release the clamp and take out the lens after the overall inspection is completed.

[0033] The implementation principle of the lens optical inspection device for lens processing according to the present invention is as follows: First, the staff places the lenses on the lens placement table 12 (the specific lens placement is existing technology, which can hold four lenses). After the lenses are placed, the staff can control the clamping component 121 to clamp the placed lenses (the specific clamping component is existing technology). After placement, the operator controls the hydraulic cylinder 31 to move it. When the hydraulic cylinder 31 moves, it can drive the mounting plate 311 to move downward, thereby driving the fixed cylinder 32 to move downward, which in turn drives the sliding rod 326 to move downward, allowing the detection ball 325 to move downward. This allows the detection ball 325 to fit into the lens placement platform 12 or the lens below. (When the hydraulic cylinder 31 drives the mounting plate 311 to move downward, it can also drive the circular mounting cylinder 252 to move downward via the placement rod 312.) When the detection ball 325 is attached to the lens placement stage 12 or the lens, the operator can control the servo motor 2 to run. When the servo motor 2 runs, it can drive the rotating rod 21 to rotate. When the rotating rod 21 rotates, it can drive the rectangular mounting plate 211 to rotate. When the rectangular mounting plate 211 rotates, it can drive the connecting rod 214 and the mounting slider 215 to rotate through the moving slider 213. Because the mounting slider 215 slides on the vortex groove 221 opened on the circular turntable 22, and the moving slider 213 slides on the moving groove 212, it is ensured that the mounting slider 215 can move along the trajectory of the vortex groove 221. When the movable slider 213 moves along the trajectory of the vortex groove 221, it can drive the hydraulic cylinder 31 to move along the trajectory through the Z-shaped connecting rod 3. When the hydraulic cylinder 31 moves along the trajectory, it can drive the detection ball 325 and the circular mounting cylinder 252 to move along the trajectory (the connection method of the detection ball 325 and the circular mounting cylinder 252 moving along the trajectory has been mentioned above). When the circular mounting cylinder 252 moves along the track, it can drive the moving rod 251 to move along the track, thereby driving the circular mounting ring 25 to move along the track (the reason why the circular mounting ring 25 moves along the track is that the circular mounting ring 25 is connected to the C-shaped connecting rod 24, and one end of the C-shaped connecting rod 24 moves through the sliding block 234 slidably set on the circular groove 233 opened on the multi-stage telescopic rod 235 and the threaded sleeve 232. Therefore, when moving along the track, the multi-stage telescopic rod 235 will gradually retract, thus ensuring that it can move along the track). Simultaneously, when the circular turntable 22 rotates, it can also drive the threaded rod 231 to rotate through the connecting rod 23. When the threaded rod 231 rotates, it can drive the threaded sleeve 232 to move vertically downward with the assistance of the guide rod 237. When the threaded sleeve 232 moves vertically downward, it can drive the circular mounting ring 25 to move vertically downward (the reason why the threaded sleeve 232 moves downward and drives the circular mounting ring 25 to move downward has been mentioned above, which ensures that the circular mounting ring 25 can move downward). When the circular mounting ring 25 moves downward, it can drive the sealing plug 253 downward through the moving rod 251. Therefore, the sealing plug 253 can squeeze the cavity inside the circular mounting cylinder 252, so that the gas inside the circular mounting cylinder 252 can be discharged from the air port 254, thereby blowing away the dust on the lens. This ensures that the lens is not scratched by dust when the detection ball 325 moves along the track, and also ensures the cleanliness of the lens. After the inspection is completed, the staff controls the line scanning camera 14 to run, thereby checking whether the lens has cracks or other defects.

[0034] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
