Description

Technical Field

[0001] The utility model relates to the technical field of lens detection, in particular to a turning mechanism for detecting military lenses. Background Art

[0002] As a kind of high-precision optical lens, the quality and precision of military lenses are higher than those of conventional civilian products. Therefore, they need to be tested by special equipment before leaving the factory.

[0003] The main contents of the inspection include visual inspection of the upper and lower surfaces of the lens, taking pictures with an industrial camera, and then analyzing and comparing based on the pictures to ensure that the produced lenses meet the usage requirements. During the inspection process, the lenses usually need to be photographed and inspected on both the upper and lower sides. Therefore, the lenses need to be flipped during inspection. The traditional way is to clamp the lenses with a robot and then flip them. During the flipping movement, the robot needs to be assisted by a visual camera for positioning, or high-precision servo cooperation to make the lenses completely flipped and placed in place, which is costly. In addition, after each lens flip is completed, the flipping mechanism needs to be reset for a second flip, which takes more time. For this reason, a flipping mechanism for military lens inspection is provided to solve the above problems. Utility Model Content

[0050] When the device is in use, the support frame 1 is installed on the side of the detection table, and the end of the L-shaped flip arm 3 is directly opposite to the bottom of the flip station. When the lens on the detection table moves to the top of the L-shaped flip arm 3, the lifting motor 43 is started, driving the driving screw 44 to rotate clockwise, so that the connecting block 45 drives the sliding seat 23 to slide upward along the fixed slide rail 41, so that the electric suction cup 5 contacts the bottom of the lens, and the lifting motor 43 stops rotating at this time, and the electric suction cup 5 completes the absorption of the lens from the bottom, and then the lifting motor 43 is started again, so that the sliding seat 23 slides upward, so that the lens is separated from the detection table, and the flip cylinder 21 drives the L-shaped flip arm 3 to rotate 180 degrees, so that the lens faces downward, and then the lifting motor 43 starts to reverse, driving the sliding seat 23 to move downward, so that the electric suction cup 5 will place the lens flipped 180 degrees into the detection station, thereby completing the lens flip;

[0051] After completing one stage of flipping, the lifting motor 43 starts forward, causing the flip cylinder 21 to lift slightly upward, and then wait for the second group of workpieces to move into place. At this time, the electric suction cup 5 adsorbs the lens from above, and then the flip cylinder 21 rises, and then the L-shaped flip arm 3 flips 180 degrees, and then the lifting motor 43 drives the flip cylinder 21 to move downward.
