DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-9One embodiment of the present invention is: a device for measuring the thickness of an optical component, comprising a measuring box 1, an observation window 2 being rotatably connected to the front of the measuring box 1, a controller 3 being fixedly installed on the front of the measuring box 1, a support plate 4 being fixedly connected to the inner wall of the measuring box 1, a motor 5 being fixedly connected to the inner wall of the measuring box 1, a laser interferometer 6 being fixedly connected to the inner wall of the measuring box 1, an electric push rod 9 being fixedly connected to the inner wall of the measuring box 1, a connecting block 10 being fixedly connected to the telescopic end of the electric push rod 9, and a Slide 11, the circumferential surface of the connecting block 10 is fixedly connected to a connecting rod 12, the inner wall of the connecting rod 12 is fixedly connected to a fixed column 13, the circumferential surface of the fixed column 13 is fixedly connected to a fixed L-plate 14, the inner wall of the support plate 4 is slidably connected to a stop block 15, the inner wall of the measuring box 1 is rotatably connected to a rotating column 16, the inner wall of the rotating column 16 is fixedly connected to a pressure column 17, a movable groove 18 is provided on the inner wall of the stop block 15, the inner wall of the connecting rod 12 is rotatably connected to a pull rod 19, and the circumferential surface of the rotating column 16 is fixedly connected to a long rod 20;

[0023] Before using the device, the operator first opens the observation window 2, and after the observation window 2 is opened, places 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, the electric push rod 9 will start, and the telescopic end of the electric push rod 9 will drive the connecting block 10 to move. The movement of the connecting block 10 will drive the connecting rod 12 to slide in the groove of the slide 11. The connecting rod 12 will drive the fixed column 13 to move during the movement, and the fixed column 13 will drive the fixed L-plate 14 to move. When the fixed L-plates 14 on both sides of the support plate 4 are close to each other for a distance, the fixed L-plates 14 will contact the computer screen placed on the top of the support plate 4. At this time, the fixed L-plates 14 can clamp and fix the computer screen, which can ensure that the computer screen cannot deviate when the thickness is measured, thereby improving the measurement accuracy of the computer screen thickness by the device and improving the measurement efficiency of the device.

[0024] The top of the support plate 4 is provided with a pushing mechanism 7 for pushing, the inner wall of the support plate 4 is provided with a protective mechanism 8 for protecting the computer screen, the connecting rod 12 is slidably connected to the inner wall of the slide 11, and the slide 11 is used to guide the connecting rod 12, the pressure column 17 is in contact with the block 15, and the pressure column 17 is used to lift the block 15, the pull rod 19 is rotatably connected to the inner wall of the long rod 20, and the fixed L plate 14 is in contact with the support plate 4;

[0025] When the electric push rod 9 is started, 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 with 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, the pressure column 17 will drive the pressure column 17 to rotate a certain angle. During the rotation of the pressure column 17, the pressure column 17 will push the pressure block 15 through the moving groove 18 on the inner wall of the pressure block 15 to move up a certain height. The pressure block 15 can lift the computer screen placed on the top of the support plate 4 before the computer screen is fixed by the fixed L plate 14. After the computer screen is clamped and fixed by the fixed L plate 14, the pressure block 15 will drop and reset. At this time, the protrusion of the outer shell behind the fixed L plate 14 can be away from the pressure block 15, so that the computer screen can remain suspended, which can be better measured by the thickness of the laser interferometer 6, thereby 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.

[0026] Overall working principle: The fixed L-plate 14 can clamp and fix the computer screen, ensuring that the computer screen cannot be offset during thickness measurement, thereby improving the device's thickness measurement accuracy for the computer screen and improving the device's measurement efficiency. The raised portion of the outer shell behind the fixed L-plate 14 can be away from the stop block 15, allowing the computer screen to remain suspended and better receive thickness measurement from the laser interferometer 6, thereby improving the overall thickness measurement accuracy of the computer screen and preventing computer screen shells of different specifications from affecting the overall thickness measurement accuracy of the computer screen.

[0027] See also Figures 1-9 On the basis of the above embodiment, in another embodiment of the present invention, the pushing mechanism 7 includes a rotating block 701, a slider 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 plate 14, the slider 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 slider 702, and the other end of the connecting column 703 is rotatably connected to the circumferential surface of the rotating block 701. The pushing plate 704 is fixedly connected to the circumferential surface of the slider 702, and the pushing plate 704 is used to push the computer screen;

[0028] When the device is started, the two fixed L plates 14 are moving away from each other, and the movement of the fixed L plates 14 will drive the rotating block 701 to move, and the movement of the rotating block 701 will pull the connecting column 703 to move. When the connecting column 703 is pulled by the rotating block 701, the movement of the connecting column 703 will drive the slider 702 to slide on the inner wall of the support plate 4, and the movement of the slider 702 will drive the pushing plate 704 to move. During the movement of the pushing plate 704, the pushing plate 704 will contact the computer screen on the top of the support plate 4 and push the computer screen, which can improve the efficiency of the device in measuring the computer screen, reduce the manual handling cost, and increase the measurement of the device;

[0029] The pushing mechanism 7 also includes a reciprocating screw 705, a second connecting block 706, an X plate 707, a limiting column 708, a rising column 709, a round block 710, a scale 711, and a pointer 712. The reciprocating 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 screw 705, the X 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 the limiting column 70 8 is used to limit the second connecting block 706. The rising column 709 is slidably connected to the inner wall of the X 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 plate 707. The pointer 712 is fixedly connected to the top of the rising column 709. The pushing plate 704 is in contact with the support plate 4. The second connecting block 706 is slidably connected to the circumferential surface of the limiting column 708. The X plate 707 and the round block 710 are connected by a spring.

[0030] After the fixed L plate 14 is clamped and fixed to the computer screen to be measured, the motor 5 will start at this time, and the output end of the motor 5 will drive the reciprocating screw rod 705 to rotate. The reciprocating screw rod 705 will drive the connecting block 2 706 to rotate during its rotation, but the connecting block 2 706 at this time is limited by the limiting column 708, and the connecting block 2 706 can only move downward through the reciprocating groove on the surface of the reciprocating screw rod 705. The downward movement of the connecting block 2 706 will drive the X-plate 707 to move downward, and the X-plate 707 will drive the rising column 709 to move downward during the movement. At the same time, the X-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 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 The screen will squeeze the round block 710 in the reverse direction. After the round block 710 is under pressure, the round block 710 will drive the rising column 709 to rise. The rise of the rising column 709 will drive the pointer 712 to rise. At this time, the pointer 712 can be aligned with the corresponding value of the scale 711. Before measurement, the X-plate 707 needs to be lowered to contact the surface of the support plate 4. At this time, the distance that the X-plate 707 has dropped is the fixed point distance. When measurement is required, the computer screen is placed on the top of the support plate 4, and the X-plate 707 continues to move down the same distance. Because of the presence of the computer screen, the round block 710 cannot contact the support plate 4 at this time. At this time, the rise of the pointer 712 can provide preliminary data of the screen thickness, which can be coordinated with the laser interferometer 6 to compare data with each other, thereby improving the measurement accuracy of the device, reducing the deviation of the computer screen thickness measurement, and increasing the use efficiency of the device.

[0031] The protective 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, and the roller 803 is rotatably connected to the inner wall of the support plate 4. The roller 803 is used to reduce friction when the computer screen moves;

[0032] When the device is started, the movement of the rotating block 701 will drive the connecting column 703 to move, and the connecting column 703 will drive the pushing plate 704 to move during the movement. The movement of the pushing plate 704 will drive the elastic telescopic rod 801 to move, and 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, and the computer screen will move on the top of the roller 803. The buffer plate 802 and the roller 803 can reduce the friction of the computer screen on the surface of the support plate 4 when it moves. The cooperation of the buffer plate 802 and the elastic telescopic rod 801 can provide a buffer when the pushing plate 704 pushes, thereby avoiding damage to the measured computer screen and reducing the measurement cost of the device.

[0033] 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.

[0034] When the device is started, the downward movement of the X-plate 707 will drive the upper sleeve column 804 to move, and at the same time, the X-plate 707 will drive the rising column 709 to move. The movement of the rising column 709 will drive the round block 710 to move. During the movement, the round block 710 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 rise 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 and 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, thereby improving the safety of the device.

[0035] The overall working principle: the pushing plate 704 will contact the computer screen on the top of the support plate 4 and push the computer screen, which can improve the efficiency of the device in measuring the computer screen, reduce the manual handling cost, and increase the measurement of the device. The round block 710 cannot contact the support plate 4 at this time. At this time, the rise of the pointer 712 can provide preliminary data on the thickness of the screen, which can cooperate with the laser interferometer 6 to compare data with each other, improve the measurement accuracy of the device, reduce the deviation in the measurement of the thickness of the computer screen, and increase the use efficiency of the device. The buffer plate 802 and the elastic telescopic rod 801 can provide a buffer when the pushing plate 704 pushes, 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, thereby improving the safety of the device.
