[0003] A thickness detection device for optical lens processing disclosed in the Chinese utility model patent application disclosure CN217179569U, although the utility model uses a designed limiter so that when the optical lens needs to be limited, the optical lens can be limited and fixed by the designed fixing seat, lifting rod, telescopic spring and limit block, so that the optical lens can be stably detected, but in the process of clamping the lens, the staff needs to manually pull the limit block upwards to fix the lens, which is less convenient and has the disadvantage of not being able to automatically add the lens for clamping. Moreover, when measuring, only one position of the lens can be detected. When the flatness difference of the lens is large, a more accurate detection result cannot be obtained, and there is a disadvantage of poor detection accuracy. Utility Model Content

There are four first springs 16 in each second groove 15, and they are symmetrically distributed in pairs. A lens body 18 is clamped in the middle of the V-shaped clamping block 17. A buffer block 19 is installed on the inner side of the second groove 15. A micro switch 20 is installed on the surface of the buffer block 19. A trigger block 21 is installed on the inner side of the V-shaped clamping block 17. The position of the trigger block 21 corresponds to the position of the micro switch 20. The material of the buffer block 19 is rubber. The micro switch 20 is electrically connected to the controller 2 through a wire. The upper surface of the workbench 1 is installed with a controller 2. The upper surface of the workbench 1 is fixedly connected with a column 22. The inner side surface of the upper part of the column 22 is provided with a second slide groove 23. The second slide groove The surface of the column 23 is slidably connected with a second slider 26, a third servo motor 24 is installed on the upper surface of the column 22, a second lead screw 25 is fixedly connected to the output end of the third servo motor 24, bearings are provided at the connection between the two ends of the second lead screw 25 and the second slide groove 23, the surface of the second lead screw 25 is threadedly connected with a second slider 26, a lifting plate 261 is fixedly connected to the surface of the second slider 26, a digital thickness gauge 27 is installed on the lower surface of the left side of the lifting plate 261, a sleeve column 28 is fixedly connected to the lower surface of the sleeve column 28, a push rod 30 is slidably connected to the inner surface of the sleeve column 28, a second spring 29 is fixedly connected to the inner top surface of the sleeve column 28, the other end of the second spring 29 is fixedly connected to the push rod 30, an arc groove 31 is provided on the lower end surface of the push rod 30, and a ball 32 rolls on the surface of the arc groove 31.

[0029] In order to achieve the purpose of improving practicality, when using, when testing the thickness of the lens, the staff will place the lens body 18 to be tested on the upper surface of the fixed block 9, so that the lens body 18 is located directly below the sleeve column 28, and then control the output end of the third servo motor 24 to rotate forward, and drive the second lead screw 25 to rotate through the third servo motor 24, so that the second slider 26 threadedly connected to the surface of the second lead screw 25 slides downward in the second slide groove 23, and drives the lifting plate 261 to move together while sliding, until the lower end surface of the push rod 30 contacts the upper surface of the lens body 18, so that the push rod 30 contacts the second spring The second servo motor 11 is turned on and the bidirectional screw 12 is driven to rotate by the second servo motor 11, so that the first slider 13 connected with the threaded surfaces of the bidirectional screw 12 slides inwards in the first slide groove 10 synchronously.

A downward force is applied, and during the process of the lens body 18 being squeezed to the middle, the ball 32 rolls on the upper surface of the lens body 18, and then when clamped, one side of the lens body 18 is prevented from tilting, so that the lens body 18 is clamped in parallel between the two V-shaped clamps 17, and the inner side of the V-shaped clamp 17 slides into the second groove 15 to squeeze the first spring 16. The first spring 16 provides a reaction force, which acts on the lens body 18 through the V-shaped clamp 17. As one side of the V-shaped clamp 17 moves in the second groove 15, the trigger block 21 on the inner side of the V-shaped clamp 17 will come into contact with the micro switch 20. At the same time, the lens body 18 is clamped between the two V-shaped clamping blocks 17. After the micro switch 20 is touched by the trigger block 21, the micro switch 20 is triggered. At this time, the micro switch 20 sends a signal to the controller 2 through the wire. After the controller 2 receives the signal from the micro switch 20, the micro switch 20 automatically sends a stop command to the second servo motor 11, so that the second servo motor 11 stops automatically, completing the automatic clamping of the lens body 18. Lens bodies 18 of different sizes can be automatically clamped, which is more convenient and more applicable, and achieves the purpose of improving practicality.

[0032] In order to achieve the purpose of improving the accuracy of the detection mechanism, when in use, after the lens body 18 is clamped, the output end of the third servo motor 24 is controlled to continue to rotate forward until the second slider 26 moves to the bottom of the second slide groove 23. At this time, the digital thickness gauge 27 is located at the origin. The probe of the digital thickness gauge 27 shrinks differently according to the different thicknesses of the lens body 18.

When the flatness fluctuates, the value displayed on the digital thickness gauge 27 will also change.
