Description

Technical Field

[0001] The present invention relates to the technical field of lens appearance detection, and in particular to an optical glued lens appearance detection device and a detection method thereof. Background Art

[0002] Optical bonded lenses are core components of precision optical devices and are widely used in high-precision imaging systems, laser optical systems, aerospace equipment and other fields. The manufacturing process of optical bonded lenses requires precision grinding, polishing and UV curing bonding technology to bond two or more pieces of optical glass into a composite lens group to achieve specific optical properties such as achromatism and reduction of spherical aberration.

[0003] Optical bonded lenses must meet sub-micron surface accuracy and nanometer surface roughness requirements. Any surface contaminants (such as fingerprint residue, dust particles or glue overflow) will cause incident light scattering, resulting in reduced imaging resolution or even system failure. Therefore, the appearance inspection process needs to be carried out in a dark field lighting environment. High-resolution industrial cameras are used to capture the diffuse reflection characteristics of the lens surface, and machine vision algorithms are used to quantify defects such as scratches, bubbles and stains.

[0004] At present, the appearance inspection process of optical bonded lenses is highly dependent on manual operation. Workers need to wear anti-static gloves and use a wiping cloth dipped in isopropyl alcohol solution to wipe the surface of the optical bonded lenses one by one in a spiral trajectory to remove pollutants on the surface of the optical bonded lenses. The repetitive accuracy of manual actions is limited, and it is easy for the edge areas to be incompletely cleaned, resulting in a decrease in detection accuracy. After each optical bonded lens is cleaned, pollutants will be adsorbed on the surface of the wiping cloth. When more than 30 lenses are wiped continuously, the pollutant load reaches a critical value and the production line needs to be stopped to replace a new wiping cloth. As a result, the production line will have multiple unplanned shutdowns every day, which will reduce detection efficiency. Summary of the invention

[0005] In view of this, the present invention provides an optical bonded lens appearance inspection device and an inspection method thereof, which can overcome the limited repetitive accuracy of manual actions and the problem that the edge area is not cleaned thoroughly, thereby causing a decrease in inspection accuracy.

[0043] In the initial state, the telescopic rod of the electric push rod 88 is in a semi-extended state; the staff puts the optically bonded lens on the right side of the slide rail 71, then opens the box cover 75, and puts a roll of wipes containing isopropyl alcohol solution on the loading shaft 78, then passes the wipes around the guide roller 79 and the sponge block 710, then winds the wipes around the reel 76, and finally closes the box cover 75, repeats this operation, puts the wipes into the placement tube 715, and the staff controls the telescopic rod of the electric push rod 88 to extend, driving the pressure plate 89 to move downward, the pressure plate 89 presses the moving plate 85 downward, the spring 86 stretches, and the moving plate 85 drives the electric suction cup 87 to move downward, and the electric suction cup 87 on the right side will contact the optically bonded lens and suck the optically bonded lens. When the optical lens is moved to the left, the telescopic rod of the electric push rod 88 is controlled to shorten, and the pressure plate 89 is driven to move upward. The pressure plate 89 no longer presses the moving plate 85. Under the action of the spring 86, the moving plate 85 and the electric suction cup 87 move upward, and the electric suction cup 87 on the right side sucks up the optically bonded lens. Then the electric guide rail 81 is controlled to drive the moving frame 82 to move left, and the moving frame 82 drives the electric suction cup 87 to move left, thereby driving the optically bonded lens to move left, and the optically bonded lens is moved to the top of the sponge plate 721 on the slide rail 71. Then the telescopic rod of the electric push rod 88 is controlled to extend, and the optically bonded lens is placed on the sponge plate 721 on the slide rail 71. Since the wiper cloth bypasses the sponge plate 721, the bottom of the optically bonded lens contacts the wiper cloth, and then The telescopic rod of the electric push rod 88 is controlled to shorten, so as to drive the optical glued lens to move upward, and the optical glued lens is removed to make room so that the rotating plate 712 can rotate downward, and then the electric guide rail 81 is controlled to drive the moving frame 82 to move rightward, and the moving frame 82 drives the electric suction cup 87 to move rightward, and moves the middle electric suction cup 87 to just above the sponge plate 721 on the slide rail 71.

At this time, the wiper in the placement box 74 contacts the side of the optically bonded lens, and then the push block 817 pushes the rotating plate 712 to rotate right, so that the placement tube 715 on the rotating plate 712 rotates downward, so that the wiper in the placement tube 715 contacts the top of the optically bonded lens, and the spring one 713 is stretched. At this time,The electric roller 725 drives the optically bonded lens to rotate, so that the wiping cloth can clean the optically bonded lens and remove pollutants on the surface of the optically bonded lens. Through the action of the sponge block 710 and the sponge plate 721, the wiping cloth can wrap the optically bonded lens to avoid incomplete cleaning of the edge area and ensure the detection accuracy. After the optically bonded lens is cleaned, the telescopic rod of the electric push rod 88 is controlled to extend, driving the pressing plate 89 and the pulling plate 819 to move downward. The pulling plate 819 no longer pulls the contact plate 818. Under the action of the spring four 814, the lifting plate 815, the wedge-shaped push block 816 and the pushing block 817 will move downward. The wedge-shaped push block 816 no longer pushes the contact wedge block 812. Under the action of the spring three 811, the sliding The block 73 moves backward, and the sliding block 73 drives the auxiliary roller 723 to move backward, and the auxiliary roller 723 is out of contact with the cleaned optical glued lens, and the pushing block 817 no longer pushes the rotating plate 712. Under the action of the spring 1 713, the rotating plate 712 rotates to the left, and the placement cylinder 715 on the rotating plate 712 rotates upward, and the wiper cloth in the placement cylinder 715 is out of contact with the top of the optical glued lens. At this time, the telescopic rod of the electric push rod 88 continues to extend, and the pressure plate 89 continues to move downward, so that the electric suction cup 87 can move downward, and the middle electric suction cup 87 will contact with the cleaned optical glued lens and suck the cleaned optical glued lens, and then the telescopic rod of the electric push rod 88 is controlled to shorten, so that the electric suction cup 87 moves downward.
