Therefore, the thickness of the lenses is very important. The thickness of the lenses needs to be tested after they are produced. Existing testing devices mostly place the lenses on a flat surface for fixation when in use.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The lens is supported by supporting balls, and pressure is applied to the lens by pressing the balls downward to push the lens to adjust its position and limit the final state of the lens, thereby achieving rapid adjustment and positioning of the lens, allowing the lens to be quickly adjusted to a horizontal state and maintained, thereby improving the accuracy of subsequent lens thickness detection.

[0016] 2. Apply thrust to the lens by pressing down the balls and push the lens to adjust its position. When the three groups of pressing balls are in contact with the lens and the pressure detected by the three groups of first pressure sensors is the same, the lens is in a horizontal state. After the lens is in a horizontal state, the third support plate moves upward until the reading of the first pressure sensor is zero. At this time, the electromagnet is energized. After the electromagnet is energized, the fixing plate is adsorbed to fix the pressure rod. At this time, the pressure of the pressing balls on the lens is small and the lens can be restricted and fixed. By detecting the pressure of the pressing balls on the lens, it is avoided that a large pressure is applied to the lens to cause damage to the lens. At the same time, the detection results of the three groups of first pressure sensors can also reflect whether the lens is in a horizontal state, further improving the accuracy of the lens thickness detection results.

[0017] 3. The end of the detection rod contacts the lens. When the second pressure sensor detects pressure, it stops. At this time, the end of the detection rod is guaranteed to contact the lens, thereby ensuring the accuracy of the detected thickness. At the same time, since the symmetry plane of the third movable plate coincides with the symmetry planes of the supporting balls and the downward pressure balls, the supporting balls and the downward pressure balls are in contact with the upper and lower surfaces of the lens respectively. Therefore, the symmetry planes of the supporting balls and the downward pressure balls coincide with the symmetry planes of the lens itself, and then the symmetry planes of the third movable plate coincide with the symmetry planes of the lens itself, so that the pressure values ​​detected by the upper and lower second pressure sensors are the same. If they are different, it means that the lens is not in a horizontal state, thereby realizing further detection of the lens state and further improving the accuracy of lens thickness detection.

[0018] 4. After the position adjustment of the lens is completed, the second telescopic member drives the limit frame to move a set distance toward the direction close to the lens. At this time, the roller contacts the side of the lens and the third elastic member is in a compressed state. At this time, the third pressure sensor detects the pressure and compares whether the pressures of multiple groups of third pressure sensors are the same. If they are the same, it means that the lens is in a horizontal state. If they are different, the second telescopic member continues to extend to increase the thrust on the lens, thereby pushing the lens to move further and adjust until it is horizontal. This realizes further detection of the lens state and can return the lens to a horizontal state when the lens moves, further improving the stability of the lens position. During subsequent detection, the roller can further limit the movement of the lens and improve the stability of the lens. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0029] like Figure 1-Figure 7As shown, an intelligent thickness tester for VR glasses lenses provided by the present invention includes a base 1, on which a plurality of first support plates 2 distributed in a circular array are fixedly installed, a threaded rod 3 is rotatably installed on the first support plate 2, and an adjusting motor for driving the plurality of threaded rods 3 to rotate synchronously is provided on the base 1, the output shaft axis of the adjusting motor is located at the distribution center of the first support plate 2, a second bevel gear 5 is fixedly installed at the end of the output shaft of the adjusting motor, the second bevel gear 5 is meshed with the first bevel gear 4 fixedly installed at the end of the threaded rod 3, a first movable plate 6 in sliding contact with the base 1 is threadedly connected to the threaded rod 3, a pillar 7 is fixedly installed on the first movable plate 6, a support ball 8 is rotatably installed on the top of the pillar 7, an L-shaped second support plate 9 is fixedly installed on the pillar 7, and the second support The vertical section of plate 9 is slidably installed with an L-shaped third support plate 11 through a sliding rod 10. A pressure rod 17 is provided on the third support plate 11. The pressure rod 17 is coaxially arranged with the pillar 7 and a downward pressure ball 18 is rotatably installed on the end of the pressure rod 17 close to the base 1. A first telescopic member 12 that drives the third support plate 11 to move is fixedly installed on the second support plate 9. The vertical sections of the second support plate 9 and the third support plate 11 are slidably installed with a sliding sleeve 13. A gear 14 located between the second support plate 9 and the third support plate 11 is rotatably installed in the sliding sleeve 13. The gear 14 is meshed with a rack 15 fixedly installed on the vertical sections of the second support plate 9 and the third support plate 11. The rotation axis of the gear 14 is located on the symmetrical plane of the support ball 8 and the downward pressure ball 18. The output end of the first telescopic member 12 is fixedly connected to the sliding sleeve 13.

[0030] Among them, a base plate 26 is provided on the base 1 and a first servo module 24 is provided on the base 1 to drive the substrate 26 to move horizontally. The substrate 26 is cross-shaped and the substrate 26 moves following the second support plate 9. Two groups of third movable plates 29 are slidably installed on the vertical section of the substrate 26 and a second servo module 36 is provided on the substrate 26 to drive the two groups of third movable plates 29 to move synchronously in the opposite direction. A detection rod 31 is provided at the end of the third movable plate 29 away from the substrate 26. A ranging plate 34 is connected to the detection rod 31. The detection plane of the ranging plate 34 is flush with the end of the detection rod 31. A laser ranging sensor 35 is fixedly installed on one group of ranging plates 34.

[0031] In actual application of this embodiment, the second bevel gear 5 is driven to rotate by adjusting the motor according to the size of the lens. The second bevel gear 5 drives multiple groups of threaded rods 3 to rotate synchronously through the meshing first bevel gear 4, and then the threaded rods 3 drive the first movable plate 6 to move the position of the adjustment pillar 7. After that, the lens to be tested is placed on multiple groups of support balls 8 for support. The support position of the support balls 8 on the lens is close to the edge of the lens.

[0032] After that, the first telescopic member 12 drives the sliding sleeve 13 to move downward. When the sliding sleeve 13 moves downward, the third support plate 11 moves downward under the action of the gear 14 and the rack 15. During the movement, the axis of the gear 14 is always located in the symmetrical plane of the supporting ball 8 and the pressing ball 18. The third support plate 11 moves downward to drive the pressure rod 17 to move until the pressing ball 18 contacts the upper surface of the lens. If the lens is in a flat state, multiple groups of pressing balls 18 contact the lens at the same time and then stop. If the lens is in a tilted state, one or two groups of pressing balls 18 will contact the lens first and push the lens to move, and finally make multiple groups of pressing balls 18 contact the upper surface of the lens synchronously. At this time, the lens is in a horizontal state, and the lens is supported by the supporting balls 8. The pressing balls 18 apply pressure to the lens to push the lens to adjust its position and limit the final state of the lens, thereby realizing rapid adjustment and positioning of the lens, so that the lens can be quickly adjusted to a horizontal state and maintained, thereby improving the accuracy of subsequent lens thickness detection.

[0033] After the lens is placed, the first servo module 24 drives the base plate 26 to move, so that the third movable plate 29 moves toward the direction close to the lens. When the detection rod 31 moves to the detection position and stops, the second servo module 36 drives the two groups of third movable plates 29 to move synchronously toward the direction of the lens until the end of the detection rod 31 contacts the lens. At this time, the distance between the ends of the two groups of detection rods 31 is the same as the distance between the two groups of ranging plates 34. The distance between the two groups of ranging plates 34 is detected by the laser ranging sensor 35 to obtain the thickness of the lens at the detection position. By adjusting the position of the base plate 26, the thickness of different positions on a straight line on the lens can be detected. After the detection is completed, the third movable plate 29 is reset, and then the base plate 26 is reset. Subsequently, the fixing of the lens by the pressing ball 18 is released and a new lens is replaced for detection.

[0034] In an example of this embodiment, the first telescopic member 12 is a first electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder, and the sliding sleeve 13 is driven to move up and down by the first electric telescopic rod.

[0035] like Figure 1-Figure 5 As shown, an intelligent thickness tester for VR glasses lenses provided by the present invention is provided. The horizontal section of the third support plate 11 is fixedly installed with a first mounting plate 16, and a pressure rod 17 is slidably installed on the first mounting plate 16. The end of the pressure rod 17 away from the base 1 is fixedly connected with a first elastic member 19, and the end of the first elastic member 19 away from the pressure rod 17 is fixedly connected to a first pressure sensor 20 fixedly installed on the third support plate 11.

[0036] Specifically, a fixing plate 21 is fixedly mounted on the pressure rod 17 , the fixing plate 21 is slidably connected to the first mounting plate 16 and is made of magnetic material. An electromagnet 22 is fixedly mounted on the first mounting plate 16 and is in sliding contact with the fixing plate 21 .

[0037] In actual application of this embodiment, the three groups of third support plates 11 move synchronously. When the pressing ball 18 contacts the lens, it will apply pressure to the first pressure sensor 20 through the pressure rod 17 and the first elastic member 19. At this time, the pressing ball 18 applies thrust to the lens and pushes the lens to adjust its position. When the three groups of pressing balls 18 are in contact with the lens and the pressures detected by the three groups of first pressure sensors 20 are the same, the lens is in a horizontal state. After the lens is in a horizontal state, the third support plate 11 moves upward until the reading of the first pressure sensor 20 is zero. At this time, the electromagnet 22 is pressed. When power is turned on, the electromagnet 22 adsorbs the fixing plate 21 to fix the pressure rod 17. At this time, the axis of the gear 14 returns to the symmetrical plane of the supporting ball 8 and the downward pressing ball 18. As a result, the pressure of the downward pressing ball 18 on the lens is relatively small and the lens can be kept restricted and fixed. By detecting the pressure of the downward pressing ball 18 on the lens, it is avoided that a large pressure is applied to the lens to cause damage to the lens. At the same time, it is also possible to reflect whether the lens is in a horizontal state through the detection results of the three groups of first pressure sensors 20, thereby further improving the accuracy of the lens thickness detection results.

[0038] In an embodiment of the present invention, the first elastic member 19 is a first spring, and can also be other elastic components such as an elastic ball. The first spring is compressed and deformed to apply pressure to the first pressure sensor 20 .

[0039] like Figure 1 、 Figure 6 As shown, an intelligent thickness tester for VR glasses lenses provided by the present invention, a mounting frame 23 is fixedly installed on the base 1, a second movable plate 25 is slidably installed on the mounting frame 23 and the second movable plate 25 is driven by a first servo module 24, a base plate 26 is slidably installed on the second movable plate 25, a horizontal section of the base plate 26 is provided with a slide groove 27, a connecting plate 28 is slidably installed in the slide groove 27, the connecting plate 28 is fixedly connected to the sliding sleeve 13 at the corresponding position and the symmetry plane of the two groups of third movable plates 29 coincides with the symmetry plane of the support ball 8 and the downward pressure ball 18.

[0040] Specifically, a second mounting plate 30 is fixedly installed at the end of the third movable plate 29, and a detection rod 31 is slidably installed on the second mounting plate 30. The tips of the two groups of detection rods 31 are opposite and coaxially arranged. The end of the detection rod 31 close to the third movable plate 29 is fixedly connected to a second elastic member 32, and the end of the second elastic member 32 away from the detection rod 31 is fixedly connected to a second pressure sensor 33 fixedly installed on the third movable plate 29.

[0041] In actual application of this embodiment, the first servo module 24 drives the second movable plate 25 to move toward the direction close to the lens, thereby moving the detection rod 31 to the position of the lens. At the same time, when the third support plate 11 is adjusted, the connecting plate 28 drives the base plate 26 to move in the vertical direction, thereby ensuring that the symmetry planes of the two sets of third movable plates 29 coincide with the symmetry planes of the support balls 8 and the downward pressure balls 18. When detecting the thickness of the lens, the end of the detection rod 31 contacts the lens and stops when the second pressure sensor 33 detects pressure. At this time, it is ensured that the end of the detection rod 31 contacts the lens, thereby ensuring that The detected thickness is accurate. At the same time, since the symmetry plane of the third movable plate 29 coincides with the symmetry planes of the supporting balls 8 and the pressing balls 18, and the supporting balls 8 and the pressing balls 18 are in contact with the upper and lower surfaces of the lens respectively, the symmetry planes of the supporting balls 8 and the pressing balls 18 coincide with the symmetry planes of the lens itself, and then the symmetry plane of the third movable plate 29 coincides with the symmetry plane of the lens itself, so that the pressure values ​​detected by the upper and lower second pressure sensors 33 are the same. If they are different, it means that the lens is not in a horizontal state, thereby realizing further detection of the lens state and further improving the accuracy of lens thickness detection.

[0042] In an embodiment of the present invention, the second elastic member 32 is a second spring, and can also be other elastic components such as an elastic ball. The second spring is compressed and deformed to apply pressure to the second pressure sensor 33 .

[0043] like Figure 1-Figure 3 、 Figure 7 As shown, an intelligent thickness tester for VR glasses lenses provided by the present invention, a fourth support plate 37 is fixedly installed on the horizontal section of the second support plate 9, a second telescopic member 38 is fixedly installed on the fourth support plate 37, a third mounting plate 39 is fixedly installed on the output end of the second telescopic member 38, a limit frame 40 is slidably installed on the third mounting plate 39, a roller 41 is rotatably installed on the limit frame 40 and one group of rollers 41 of the limit frame 40 is driven by a motor, a third elastic member 42 is fixedly installed on the third mounting plate 39, and the end of the third elastic member 42 away from the third mounting plate 39 is fixedly connected to a third pressure sensor 43 fixedly installed on the limit frame 40.

[0044] In actual application of this embodiment, after the position adjustment of the lens is completed, the second telescopic member 38 drives the limit frame 40 to move a set distance in the direction close to the lens. At this time, the roller 41 contacts the side of the lens and the third elastic member 42 is in a compressed state. At this time, the third pressure sensor 43 detects the pressure and compares whether the pressures of multiple groups of third pressure sensors 43 are the same. If they are the same, it means that the lens is in a horizontal state. If they are different, the second telescopic member 38 is continued to extend to increase the thrust on the lens, thereby pushing the lens to move further and adjust until it is horizontal, thereby realizing further detection of the lens state and being able to return the lens to a horizontal state when the lens moves, further improving the stability of the lens position. During subsequent detection, the roller 41 can further limit the movement of the lens and improve the stability of the lens. Subsequently, the motor drives one of the groups of rollers 41 to rotate to rotate the lens, so that different positions of the lens can be moved to a position that can be detected by the detection rod 31, thereby realizing comprehensive detection of the lens thickness and further improving the accuracy of the lens thickness detection.

[0045] In an embodiment of the present invention, the third elastic member 42 is a third spring, and can also be other elastic components such as an elastic ball. The third spring is compressed to apply pressure to the third pressure sensor 43 .

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
