Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] Please refer to Figures 1 - 9 , an embodiment of the present invention is: a measuring device for the thickness of an optical component, including a measuring box 1, an observation window 2 is rotatably connected to the front part of the measuring box 1, a controller 3 is fixedly installed on the front part of the measuring box 1, a support plate 4 is fixedly connected to the inner wall of the measuring box 1, a motor 5 is fixedly connected to the inner wall of the measuring box 1, a laser interferometer 6 is fixedly connected to the inner wall of the measuring box 1, an electric push rod 9 is fixedly connected to the inner wall of the measuring box 1, a connecting block 10 is fixedly connected to the telescopic end of the electric push rod 9, a slideway 11 is fixedly connected to the inner wall of the measuring box 1, a connecting rod 12 is fixedly connected to the circumferential surface of the connecting block 10, a fixed column 13 is fixedly connected to the inner wall of the connecting rod 12, a fixed L-shaped plate 14 is fixedly connected to the circumferential surface of the fixed column 13, an abutting block 15 is slidably connected to the inner wall of the support plate 4, a rotating column 16 is rotatably connected to the inner wall of the measuring box 1, a pressing column 17 is fixedly connected to the inner wall of the rotating column 16, a moving groove 18 is opened in the inner wall of the abutting block 15, a pull rod 19 is rotatably connected to the inner wall of the connecting rod 12, and a long rod 20 is fixedly connected to the circumferential surface of the rotating column 16; Before using the device, the operator first opens the observation window 2. After opening the observation window 2, place the front of the computer screen whose thickness needs to be measured face up on the top of the support plate 4. After the support plate 4 is placed stably, at this time, the electric push rod 9 will start. The telescopic end of the electric push rod 9 will drive the first connecting block 10 to move. The movement of the first connecting block 10 will drive the connecting rod 12 to slide in the groove of the slideway 11. During the movement of the connecting rod 12, it will drive the fixed column 13 to move. The fixed column 13 will drive the fixed L-shaped plate 14 to move. When the fixed L-shaped plates 14 on both sides of the support plate 4 approach each other by a certain distance, the fixed L-shaped plate 14 will contact the computer screen placed on the top of the support plate 4. At this time, the fixed L-shaped plate 14 can clamp and fix the computer screen, ensuring that the computer screen will not shift during the thickness measurement, improving the thickness measurement accuracy of the device for the computer screen and the measurement efficiency of the device. A pushing mechanism 7 for pushing is provided on the top of the support plate 4. A protection mechanism 8 for protecting the computer screen is provided on the inner wall of the support plate 4. The connecting rod 12 is slidably connected to the inner wall of the slideway 11, and the slideway 11 is used to guide the connecting rod 12. The pressing column 17 contacts the abutting block 15, and the pressing column 17 is used to lift the abutting block 15. The pull rod 19 is rotatably connected to the inner wall of the long rod 20. The fixed L-shaped plate 14 contacts the support plate 4; When the electric push rod 9 starts, the movement of the connecting rod 12 will drive the pull rod 19 to move. When the pull rod 19 moves, it will drive the long rod 20 to rotate around the rotating column 16 as the rotation center. The rotation of the long rod 20 will drive the rotating column 16 to rotate. During the rotation of the rotating column 16, it will drive the pressing column 17 to rotate by a certain angle. During the rotation of the pressing column 17, the pressing column 17 will push the abutting block 15 to move upward by a certain height through the moving groove 18 on the inner wall of the abutting block 15. The abutting block 15 can lift the computer screen placed on the top of the support plate 4 before the computer screen is clamped and fixed by the fixed L-shaped plate 14. After the computer screen is clamped and fixed by the fixed L-shaped plate 14, the abutting block 15 will descend and reset. At this time, the protruding part of the shell behind the fixed L-shaped plate 14 can be far away from the abutting block 15, enabling the computer screen to be suspended, better receiving the thickness measurement by the laser interferometer 6, improving the overall thickness measurement accuracy of the computer screen, and avoiding the influence of computer screen shells of different specifications on the overall thickness measurement accuracy of the computer screen.

[0014] Overall working principle: The fixed L-shaped plate 14 can clamp and fix the computer screen, ensuring that the computer screen will not shift during the thickness measurement, improving the thickness measurement accuracy of the device for the computer screen and the measurement efficiency of the device. The protruding part of the shell behind the fixed L-shaped plate 14 can be far away from the abutting block 15, enabling the computer screen to be suspended, better receiving the thickness measurement by the laser interferometer 6, improving the overall thickness measurement accuracy of the computer screen, and avoiding the influence of computer screen shells of different specifications on the overall thickness measurement accuracy of the computer screen.

[0015] Please refer to Figures 1 - 9 , on the basis of the above embodiments, in another embodiment of the present invention, the pushing mechanism 7 includes a rotating block 701, a sliding block 702, a connecting column 703, and a pushing plate 704. The rotating block 701 is rotatably connected to the inner wall of the fixed L-shaped plate 14, the sliding block 702 is slidably connected to the inner wall of the support plate 4, one end of the connecting column 703 is rotatably connected to the circumferential surface of the sliding block 702, the other end of the connecting column 703 is rotatably connected to the circumferential surface of the rotating block 701, and the pushing plate 704 is fixedly connected to the circumferential surface of the sliding block 702 and is used to push the computer screen; When the device is started, during the process of the two fixed L-shaped plates 14 moving away from each other, the movement of the fixed L-shaped plate 14 will drive the movement of the rotating block 701. The movement of the rotating block 701 will pull the connecting column 703 to move. During the process of the connecting column 703 being pulled by the rotating block 701, the movement of the connecting column 703 will drive the sliding block 702 to slide on the inner wall of the support plate 4. The movement of the sliding block 702 will drive the movement of the pushing plate 704. During the movement of the pushing plate 704, the pushing plate 704 will contact and push the computer screen on the top of the support plate 4, which can improve the measurement efficiency of the device for the computer screen, reduce the manual handling cost, and increase the measurement of the device; The pushing mechanism 7 further includes a reciprocating lead screw 705, a second connecting block 706, an X-shaped plate 707, a limiting column 708, a rising column 709, a round block 710, a scale 711, and a pointer 712. The reciprocating lead screw 705 is fixedly connected to the output end of the motor 5. The second connecting block 706 is movably connected to the circumferential surface of the reciprocating lead screw 705. The X-shaped plate 707 is fixedly connected to the bottom of the second connecting block 706. The limiting column 708 is fixedly connected to the inner wall of the measuring box 1 and is used to limit the second connecting block 706. The rising column 709 is slidably connected to the inner wall of the X-shaped plate 707. The round block 710 is fixedly connected to the bottom of the rising column 709. The scale 711 is fixedly connected to the top of the X-shaped plate 707. The pointer 712 is fixedly connected to the top of the rising column 709. The pushing plate 704 contacts the support plate 4. The second connecting block 706 is slidably connected to the circumferential surface of the limiting column 708. The X-shaped plate 707 and the round block 710 are connected by a spring; After the fixed L-shaped plate 14 clamps and fixes the computer screen to be measured, the motor 5 will be started at this time. The output end of the motor 5 will drive the reciprocating lead screw 705 to rotate. When the reciprocating lead screw 705 rotates, it will drive the second connecting block 706 to rotate. However, at this time, the second connecting block 706 is limited by the limiting column 708, and the second connecting block 706 can only move downward through the reciprocating groove on the surface of the reciprocating lead screw 705. The downward movement of the second connecting block 706 will drive the X-shaped plate 707 to move downward. During the movement of the X-shaped plate 707, it will drive the rising column 709 to move downward. At the same time, the X-shaped plate 707 will also drive the scale 711 to move. The movement of the rising column 709 will drive the round block 710 to move. After the round block 710 moves downward for a certain distance, the round block 710 will contact the computer screen on the top of the support plate 4. At this time, the round block 710 will move downward, and the computer screen will reversely press the round block 710. After the round block 710 is subjected to pressure, the round block 710 will drive the rising column 709 to rise. The rising of the rising column 709 will drive the pointer 712 to rise. At this time, the pointer 712 can be aligned with the value corresponding to the scale 711. Before measurement, the X-shaped plate 707 needs to be lowered to contact the surface of the support plate 4. At this time, the distance that the X-shaped plate 707 descends is the fixed-point distance. When measuring, place the computer screen on the top of the support plate 4, and the X-shaped plate 707 continues to move downward by the same distance. Because of the existence of the computer screen, the round block 710 cannot contact the support plate 4 at this time. The rising of the pointer 712 at this time can provide preliminary data on the screen thickness, which can cooperate with the laser interferometer 6 to compare data with each other, improve the measurement accuracy of the device, reduce the deviation of the computer screen thickness measurement, and increase the use efficiency of the device; The protection mechanism 8 includes an elastic telescopic rod 801, a buffer plate 802, and a roller 803. The elastic telescopic rod 801 is fixedly connected to the inner wall of the push plate 704. The buffer plate 802 is fixedly connected to the telescopic end of the elastic telescopic rod 801. The roller 803 is rotatably connected to the inner wall of the support plate 4, and the roller 803 is used to reduce the friction when the computer screen moves; When the device is started, the movement of the rotating block 701 will drive the connecting column 703 to move. During the movement of the connecting column 703, it will drive the push plate 704 to move. The movement of the push plate 704 will drive the elastic telescopic rod 801 to move. The movement of the elastic telescopic rod 801 will drive the buffer plate 802 to move. During the movement of the buffer plate 802, it can push the computer screen on the surface of the support plate 4. The computer screen will move on the top of the roller 803. Through the buffer plate 802 and the roller 803, the computer screen on the surface of the support plate 4 can reduce the friction when moving. The cooperation of the buffer plate 802 and the elastic telescopic rod 801 can provide buffering when the push plate 704 pushes, avoid damaging the measured computer screen, and reduce the measurement cost of the device The protection mechanism 8 further includes an upper sleeve column 804 and a lower sleeve column 805. The upper sleeve column 804 is fixedly connected to the bottom of the X plate 707, and the lower sleeve column 805 is fixedly connected to the top of the round block 710. The buffer plate 802 contacts the support plate 4, and the lower sleeve column 805 contacts the upper sleeve column 804. When the device is started, the downward movement of the X plate 707 will drive the upper sleeve column 804 to move. At the same time, the X plate 707 will drive the rising column 709 to move, and the movement of the rising column 709 will drive the round block 710 to move. During the movement of the round block 710, it will drive the lower sleeve column 805 to move. When the round block 710 contacts the computer screen, the computer screen squeezes the round block 710, causing the round block 710 to rise. The rising of the round block 710 can drive the lower sleeve column 805 to rise. The upper sleeve column 804 and the lower sleeve column 805 can always wrap the round block 710 with the spring in the X plate 707 when the device measures the computer screen, which can prevent the operator's fingers from being pinched when checking and arranging the measurement area, improving the safety of using the device.

[0016] Overall working principle: The pushing plate 704 will contact and push the computer screen on the top of the support plate 4, which can improve the measurement efficiency of the device for the computer screen, reduce the manual handling cost, and increase the measurement of the device. At this time, the round block 710 cannot contact the support plate 4. At this time, the rising of the pointer 712 can provide preliminary data on the screen thickness, which can cooperate with the laser interferometer 6 to compare data with each other, improve the measurement accuracy of the device, reduce the deviation of the computer screen thickness measurement, and increase the use efficiency of the device. The cooperation between the buffer plate 802 and the elastic telescopic rod 801 can provide buffering when the pushing plate 704 is pushed, avoiding damage to the measured computer screen and reducing the measurement cost of the device. The upper sleeve column 804 and the lower sleeve column 805 can always wrap the round block 710 with the spring in the X plate 707 when the device measures the computer screen, which can prevent the operator's fingers from being pinched when checking and arranging the measurement area, improving the safety of using the device.

The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be realized by using existing technologies.
