Description

Technical Field

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

[0002] Optical glued lenses are core components of precision optical devices and are widely used in fields such as high-precision imaging systems, laser optical systems, and aerospace equipment. The manufacturing process of optical glued lenses requires precision grinding, polishing, and ultraviolet curing gluing 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 glued lenses need to meet the requirements of sub-micron surface form accuracy and nano-scale surface roughness. Any surface contaminants (such as fingerprint residues, dust particles, or glue overflow) will cause incident light scattering, resulting in a decrease in imaging resolution or even system failure. Therefore, in the appearance detection process, in a dark-field illumination environment, a high-resolution industrial camera is used to capture the diffuse reflection characteristics of the lens surface, and machine vision algorithms are combined to quantitatively determine defects such as scratches, bubbles, and stains.

[0004] Currently, the appearance detection process of optical glued lenses highly relies 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 glued lenses one by one in a spiral trajectory to remove the contaminants on the surface of the optical glued lenses. The repetitive accuracy of manual actions is limited, and it is easy to have incomplete cleaning in the edge area, resulting in a decrease in detection accuracy. After each optical glued lens is cleaned, the wiping cloth surface will adsorb contaminants. When continuously wiping more than 30 pieces, the contaminant load reaches the critical value, and it is necessary to stop the machine to replace the new wiping cloth. The production line will have multiple unplanned stops every day due to this, which will reduce the detection efficiency. Summary of the Invention

Three sleeves 83 are evenly spaced and connected to the front side of the moving frame 82 from left to right. Sleeve rods 84 are slidably connected to the inside of the sleeves 83. The lower ends of the three sleeve rods 84 are jointly connected to the moving plate 85. Second springs 86 are sleeved on the sleeve rods 84.

[0048] Referring to Figures 14-17 , the pushing assembly includes a slide rod 810, a third spring 811, a contact wedge block 812, a sliding frame 813, a fourth spring 814, a lifting plate 815, a wedge-shaped push block 816, a pushing block 817, a contact plate 818, and a pulling plate 819.

The rear side of the lifting plate 815 is connected to the contact plate 818. The pulling plate 819 is bolted to the rear side of the pressing plate 89.

[0049] In the initial state, the telescopic rod of the electric push rod 88 is in a semi-extended state; the staff places the optical cemented lens on the right side of the slide rail 71, then opens the box cover 75, puts a roll of wiping cloth containing isopropyl alcohol solution on the loading shaft 78, then winds the wiping cloth around the guide roller 79 and the sponge block 710, then winds the wiping cloth around the take-up shaft 76, and finally closes the box cover 75. Repeat this operation to put the wiping cloth into the placing cylinder 715. Then the staff controls the telescopic rod of the electric push rod 88 to extend, driving the pressing plate 89 to move downward. The pressing plate 89 presses the moving plate 85 downward, and the second spring 86 stretches. The moving plate 85 drives the electric suction cup 87 to move downward. The right electric suction cup 87 will contact the optical cemented lens and suck the optical cemented lens. At this time, control the telescopic rod of the electric push rod 88 to shorten, driving the pressing plate 89 to move upward. The pressing plate 89 no longer presses the moving plate 85. Under the action of the second spring 86, the moving plate 85 and the electric suction cup 87 move upward. The right electric suction cup 87 sucks up the optical cemented lens. Then control the electric guide rail 81 to drive the moving frame 82 to move leftward. The moving frame 82 drives the electric suction cup 87 to move leftward, thus driving the optical cemented lens to move leftward. Move the optical cemented lens directly above the sponge plate 721 on the slide rail 71. Then control the telescopic rod of the electric push rod 88 to extend, and place the optical cemented lens on the sponge plate 721 on the slide rail 71. Since the wiping cloth bypasses the sponge plate 721, the bottom of the optical cemented lens contacts the wiping cloth. Then control the telescopic rod of the electric push rod 88 to shorten, driving the optical cemented lens to move upward, moving the optical cemented lens away to create space for the rotating plate 712 to rotate downward. Then control the electric guide rail 81 to drive the moving frame 82 to move rightward. The moving frame 82 drives the electric suction cup 87 to move rightward, moving the middle electric suction cup 87 directly above the sponge plate 721 on the slide rail 71. At this time, control the telescopic rod of the electric push rod 88 to continue to shorten, so that the pressing plate 89 continues to move upward. The pressing plate 89 drives the pulling plate 819 to move upward. The pulling plate 819 pulls the contact plate 818 to move upward. The contact plate 818 drives the lifting plate 815 to move upward. The fourth spring 814 compresses. The lifting plate 815 drives the wedge-shaped push block 816 and the pushing block 817 to move upward. The inclined surface of the wedge-shaped push block 816 contacts the inclined surface of the contact wedge block 812. Therefore, the wedge-shaped push block 816 can push the contact wedge block 812 forward. The contact wedge block 812 drives the sliding block 73 to move forward. The third spring 811 stretches. The sliding block 73 drives the connecting block 722 and the auxiliary roller 723 to move forward. The auxiliary roller 723 pushes the optical cemented lens forward, making the optical cemented lens contact the electric roller 725. At this time, the wiping cloth in the placing box 74 contacts the side of the optical cemented lens. Then the pushing block 817 will push the rotating plate 712 to rotate rightward, causing the placing cylinder 715 on the rotating plate 712 to rotate downward, making the wiping cloth in the placing cylinder 715 contact the top of the optical cemented lens. The first spring 713 stretches. At this time,The electric roller 725 drives the optical cemented lens to rotate, enabling the wiping cloth to clean the optical cemented lens, removing the pollutants on the surface of the optical cemented lens. Through the action of the sponge block 710 and the sponge plate 721, the wiping cloth can wrap the optical cemented lens, avoiding the incomplete cleaning of the edge area and ensuring the detection accuracy. After the cleaning of the optical cemented lens is completed, the telescopic rod of the electric push rod 88 is extended, driving the pressure plate 89 and the pull plate 819 to move downward. The pull 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 block 73 moves backward. The sliding block 73 drives the auxiliary roller 723 to move backward, and the auxiliary roller 723 disengages from the cleaned optical cemented lens. The pushing block 817 no longer pushes the rotating plate 712. Under the action of the spring one 713, the rotating plate 712 rotates to the left, and the placing cylinder 715 on the rotating plate 712 rotates upward. The wiping cloth in the placing cylinder 715 disengages from the top of the optical cemented 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. The middle electric suction cup 87 will contact the cleaned optical cemented lens and suck it. Then, the telescopic rod of the electric push rod 88 is shortened to make the electric suction cup 87 move upward, sucking up the cleaned optical cemented lens. Then, the electric guide rail 81 is controlled to drive the electric suction cup 87 to move to the left. The electric suction cup 87 drives the cleaned optical cemented lens to move to the left, moving the cleaned optical cemented lens to directly above the placing table 3. The telescopic rod of the electric push rod 88 is extended to make the electric suction cup 87 move downward, placing the cleaned optical cemented lens on the placing table 3. The vision camera one 4 and the vision camera two 6 can photograph the cleaned optical cemented lens to perform an appearance inspection on the cleaned optical cemented lens. The vision camera one 4 and the vision camera two 6 can be connected to an external computer, and the vision camera one 4 and the vision camera two 6 feedback signals to the external computer. The staff can understand the appearance of the optical cemented lens through the external computer. After the inspection is completed, according to the above operations, the left electric suction cup 87 sucks up the inspected optical cemented lens and unloads it. The right electric suction cup 87 places the optical cemented lens on the sponge plate 721 on the slide rail 71. The middle electric suction cup 87 places the cleaned optical cemented lens on the placing table 3. The left electric suction cup 87 unloads the inspected optical cemented lens. Loading, cleaning and unloading can be carried out simultaneously, so that the appearance inspection of the optical cemented lens can be continuously carried out, improving the inspection efficiency. After the part of the wiping cloth in contact with the sponge block 710 and the sponge plate 721 adsorbs too many pollutants, the servo motor one 77 and the servo motor two 718 are started.The output shaft of servo motor 1 77 drives winding shaft 1 76 to rotate. Winding shaft 1 76 winds the wiping cloth, winding the dirty part of the wiping cloth onto winding shaft 1 76. The wiping cloth will be released from loading shaft 1 78 for replacing the wiping cloth. Under the action of damping sleeve 1 781, the friction force of loading shaft 1 78 during rotation can be increased to prevent loading shaft 1 78 from rotating easily, thereby avoiding the loosening of the wiping cloth. The output shaft of servo motor 2 718 drives winding shaft 2 717 to rotate. Winding shaft 2 717 winds the wiping cloth, winding the dirty part of the wiping cloth onto winding shaft 2 717. The wiping cloth will be released from loading shaft 2 719 for replacing the wiping cloth. Under the action of damping sleeve 2 7191, the friction force of loading shaft 2 719 during rotation can be increased to prevent loading shaft 2 719 from rotating easily, thereby avoiding the loosening of the wiping cloth. In this way, the wiping cloth can be automatically replaced without frequent shutdown operations, thus further improving the detection efficiency.
