Description

Technical Field

[0001] The invention belongs to the technical field of optical glass detection, and specifically relates to a device for detecting the surface roughness of an optical flat plate of a glass material. Background Art

[0002] Optical glass is a glass material used to manufacture optical devices such as lenses and prisms. It has high transmittance and good optical properties. The detection of optical glass surface roughness is crucial to the performance of optical devices. The optical glass roughness detection device is a precision instrument specially designed to measure and evaluate the surface roughness of optical glass. It has a wide range of applications in optical component manufacturing, semiconductor manufacturing, optical instrument research and development, etc. It can be used to evaluate the surface quality of optical glass lenses, prisms, filters and other components to ensure that they meet specific optical performance requirements.

[0003] The prior art also proposes some solutions: for example, a patent with publication number CN118067071A discloses an optical glass surface roughness detection device, in which a mounting block and a covering are arranged on a base, and before the stylus performs roughness detection on the optical glass, the covering is wrapped around the stylus, so that the covering contacts the optical glass instead of the stylus, and the roughness detection is performed on the optical glass, so that the stylus will not be worn. After the detection is completed, the covering is removed and replaced. Therefore, the stylus of the present invention will not be worn and the phenomenon of needle skipping will not occur.

[0004] When the existing device performs roughness detection on optical glass, it performs detection by contacting the optical glass with a stylus. Since there may be some impurities on the surface of the optical glass, the presence of impurities may cause the measuring instrument to deviate when contacting or scanning the surface of the optical glass, thereby introducing measurement errors. After the stylus contacts the optical glass, its outer wall will absorb the impurities, which may be brought to other areas of the optical glass surface, causing secondary contamination.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 10 As shown, the present invention provides a technical solution: a device for detecting the surface roughness of an optical flat plate of a glass material, comprising a base plate 1, a lifting platform 2 is fixedly installed on the top of the base plate 1, an optical glass 3 is placed above the lifting platform 2, a detection platform 4 is fixedly installed directly above the base plate 1, cleaning rods 5 are symmetrically arranged directly above the detection platform 4, the outer wall of each cleaning rod 5 is fixedly connected to a connecting shaft 6, the outer wall of the cleaning rod 5 is in contact with the surface of the optical glass 3, a plurality of stylus heads 32 are arranged directly above the optical glass 3, a lifting assembly is arranged on the outer side of the stylus head 32, the lifting assembly is used to drive the stylus head 32 to descend and touch the surface of the optical glass 3 for detection, a squeezing assembly is arranged above both sides of the two cleaning rods 5, and when the lifting assembly moves, it will drive the squeezing assembly to push the two connecting shafts 6 to slide toward the outer side of the detection platform 4, and a self-cleaning assembly for cleaning the cleaning rods 5 is arranged above the detection platform 4.

[0035] During operation: in the initial state, the lifting platform 2 is located below the testing platform 4, the optical glass 3 is placed directly above the lifting platform 2, and the lifting platform 2 is controlled to rise so that the top surface of the lifting platform 2 is flush with the top surface of the testing platform 4. At this time, the top surface of the optical glass 3 is in contact with the outer wall of the cleaning rod 5, and then the lifting component is started. The lifting component will drive the stylus head 32 to descend, so that the stylus head 32 gradually approaches the top surface of the optical glass 3 for roughness detection, and when the stylus head 32 descends, it will drive the extrusion component to descend, and the extrusion component will push the two connecting shafts 6 to slide toward the outside of the testing platform 4. During the sliding process of the connecting shaft 6, it will drive the cleaning rod 5 to move along the surface of the optical glass 3, and during the movement, the two cleaning rods 5 will also rotate. Therefore, when the two cleaning rods 5 continuously move along the surface of the optical glass 3 and rotate in coordination, the impurities on the surface of the optical glass 3 The mass energy is removed, and the impurity removal by the cleaning rod 5 will not cause scratches on the surface of the optical glass 3, but some impurities will adhere to the outer wall of the cleaning rod 5. When the two cleaning rods 5 leave the surface of the optical glass 3 and continue to slide outward, the self-cleaning component can remove the impurities adhered to the cleaning rod 5. After the two cleaning rods 5 are reset, they remain in a clean state, which is convenient for subsequent continued use. Through the above embodiment, in the process of driving the stylus head 32 to descend and gradually touch the surface of the optical glass 3 for detection through the lifting component, the two cleaning rods 5 can remove impurities along the surface of the optical glass 3. The removal of impurities is achieved during the descent of the stylus head 32, which saves time for separate impurity removal and improves work efficiency. When the cleaning rod 5 leaves the surface of the optical glass 3 and passes through the self-cleaning component, it can remove impurities adhered to itself, so that it can remain in a clean state after being reset.

[0036] It should be noted that the measurement method of the stylus head is contact measurement, that is, the stylus is in direct contact with the surface to be measured, and the roughness is measured by sensing the tiny undulations on the surface. During measurement, the stylus is driven by a driver to move along the contour of the surface to be measured. Due to the uneven surface contour, the stylus makes vertical undulating motion in a direction perpendicular to the contour of the surface to be measured. This motion is converted into an electrical signal by a sensor. After amplification and processing, the surface contour assessment parameter value can be displayed on a display, and the surface contour graph can also be output through a recording instrument.

[0037] like Figures 7 and 8 As shown, the extrusion assembly includes two groups of extrusion plates 26, each group of extrusion plates 26 has two extrusion plates, and an outer push rod 28 is fixedly connected between the bottoms of every two adjacent extrusion plates 26. A V-shape is formed between the two extrusion plates 26 and the outer push rod 28. The outer wall of the outer push rod 28 fits with the outer wall of the connecting shaft 6. A movable groove 27 is opened on the inner wall of each extrusion plate 26. The connecting shaft 6 and the movable groove 27 are movably connected and adapted to each other. Rotation components that drive the cleaning rod 5 to rotate are arranged on both sides of the connecting shaft 6.

[0038] During operation: when the lifting assembly drives the stylus head 32 to descend, it will also drive the extrusion plate 26 and the outer push rod 28 to descend. During the descending process, the outer wall of the outer push rod 28 will first squeeze the connecting shaft 6, so that the connecting shaft 6 enters the inner wall of the movable groove 27, and the connecting shaft 6 will slide along the inner wall of the movable groove 27. Therefore, the two connecting shafts 6 will gradually move to the outside of the detection table 4, so that the two cleaning rods 5 can move along the surface of the optical glass 3, and during the movement of the cleaning rod 5, it can be rotated by the rotation assembly, and the direction of rotation is the same as the direction of movement. Under the mutual cooperation of movement and rotation, the cleaning rod 5 achieves the effect of removing impurities on the surface of the optical glass 3.

[0039] like Figure 3 to Figure 4 As shown, the self-rotating assembly includes a plurality of rack plates 12, and the plurality of rack plates 12 are fixedly mounted on the top of the detection platform 4. The outer wall of the connecting shaft 6 is symmetrically fixedly connected with a gear 9, and the teeth of the gear 9 are meshed with a gear 2 10. The outer wall of the connecting shaft 6 is symmetrically rotationally connected with a coupling 11, and the inner wall of the coupling 11 is rotationally connected with the shaft rod of the gear 2 10, and the teeth of the gear 2 10 are meshed with the teeth of the rack plate 12.

[0040] During operation: when the extrusion plate 26 descends to squeeze the cleaning rod 5 and the connecting shaft 6 to move along the surface of the optical glass 3, the gear 2 10 will mesh with the rack plate 1 12 and cause the gear 2 10 to rotate. When the gear 2 10 rotates, it will drive the gear 1 9 to rotate, and the gear 1 9 will drive the connecting shaft 6 and the cleaning rod 5 to rotate. With the gear 2 10 as the medium for the rotation direction, when the connecting shaft 6 moves toward the outer wall of the detection table 4, its rotation direction is the same as the movement direction, so that the cleaning rod 5 can remove impurities during its movement and rotation, and the position of the gear 2 10 can be fixed together with the position of the connecting shaft 6 through the coupling 11.

[0041] like Figures 4 to 5 As shown, the self-cleaning component includes two groups of cleaning plates 14, each group of cleaning plates 14 has two cleaning plates, and the two groups of cleaning plates 14 are located on both sides of the optical glass 3. The outer walls of the cleaning plates 14 are fixedly connected with a plurality of rotating shafts 15, and the outer walls on both sides of the cleaning plates 14 are rotatably connected with clamping members 16, and the clamping members 16 are fixedly installed on the top of the detection platform 4. A collecting groove 38 is opened on the inner wall of the top surface of the detection platform 4, and the collecting groove 38 is located directly below the cleaning plate 14. A linkage component for driving the cleaning plate 14 to rotate is arranged below the connecting shaft 6.

[0042] During operation: when the cleaning rod 5 moves away from the surface of the optical glass 3, its outer wall will contact the rotating shaft 15, and when the cleaning rod 5 continues to move, it will drive the cleaning plate 14 and the rotating shaft 15 to rotate through the linkage assembly, and the cleaning plate 14 rotates in opposite directions to the rotating shaft 15. Therefore, the outer wall of the cleaning rod 5 will generate a force of mutual contact with the outer wall of the rotating shaft 15, and the rotating shaft 15 rotates in the opposite direction to repeatedly hit the outer wall of the cleaning rod 5, thereby achieving the effect of removing impurities adhered to the cleaning rod 5, and the impurities removed from the optical glass 3 by the cleaning rod 5 and the impurities cleaned by itself will fall into the collection tank 38 for impurity collection.

[0043] like Figures 4 to 5 As shown, the linkage assembly includes a plurality of rack plates 13, each rack plate 13 is fixedly mounted on one side of the coupling 11, and the outer walls on both sides of each cleaning plate 14 are symmetrically fixedly connected with a gear 3 17, and the teeth of the gear 3 17 are meshed with the teeth of the rack plate 13.

[0044] During operation: when the cleaning rod 5 moves to one side of the cleaning plate 14, the rack plate 2 13 at its bottom will mesh with the gear 3 17 and cause the gear 3 17 to rotate, and the direction of rotation of the gear 3 17 is opposite to the direction of rotation of the cleaning rod 5. The two touch each other and rotate with each other, and the outer wall of the cleaning rod 5 will be repeatedly slapped to achieve the effect of self-cleaning.

[0045] like Figure 2 and Figure 6 As shown, both ends of the two connecting shafts 6 are fixedly connected with an inner slider 8, and a plurality of fixed seats 7 are fixedly installed on the top of the base plate 1. Each inner slider 8 is slidably connected and matched with the inner wall of each fixed seat 7, and a slide bar groove 20 is opened on the top surface of the fixed seat 7. A slide bar 21 is fixedly connected to the top of the inner slider 8, and the slide bar 21 is slidably connected and matched with the slide bar groove 20.

[0046] During operation: by means of the set fixed seat 7 and the inner sliding block 8, when the extrusion plate 26 pushes the connecting shaft 6 to slide outward, the two cleaning rods 5 always move along a straight line. Therefore, during the movement, the outer wall of the cleaning rod 5 can always fit the surface of the optical glass 3 without position displacement. In addition, by means of the set sliding bar groove 20 and the sliding bar 21, the moving distance of the connecting shaft 6 and the cleaning rod 5 is limited, and the inner sliding block 8 can also be made more stable during the sliding process inside the fixed seat 7.

[0047] like Figure 2 and Figure 6As shown, a damping rod 18 is fixedly connected to one side of the inner slider 8, one end of the damping rod 18 is fixedly connected to the inner side surface of the fixing seat 7, and a return spring 19 is provided on the outer wall of the damping rod 18, one end of the return spring 19 is fixedly connected to one side of the inner slider 8, and the other end of the return spring 19 is fixedly connected to the inner side surface of the fixing seat 7.

[0048] During operation: through the damping rod 18 and the reset spring 19, when the inner slider 8 slides on the inner wall of the fixed seat 7, the cleaning rod 5 will squeeze the reset spring 19 to deform when cleaning impurities, and after the detection is completed, when the contact needle head 32 is driven to rise and reset by the lifting assembly, the extrusion plate 26 can also be reset. At this time, under the action of the damping rod 18 and the reset spring 19, the two cleaning rods 5 can also be reset, so that the two cleaning rods 5 can perform the cleaning work of the next detection.

[0049] like Figure 6 and Fig. 9 As shown, the lifting assembly includes a fixed seat 23, which is fixedly installed above the fixed seat 1 7, and the inner sliding block 24 is slidably connected inside the fixed seat 23. The telescopic cylinder 22 is fixedly installed on the top of the fixed seat 23, and the output end of the telescopic cylinder 22 is fixedly connected to the top of the inner sliding block 24. One side of the inner sliding block 24 is fixedly connected to a fixed seat 3 25, and the fixed seat 3 25 is fixedly connected to the top of the extrusion plate 26. A fixed plate 31 is arranged on one side of the fixed seat 3 25, and a plurality of contact pins 32 are located below the fixed plate 31.

[0050] During operation: the telescopic cylinder 22 is started, and its output end will drive the inner slider 24 to slide downward inside the fixed seat 23. During the sliding process, the fixed plate 31 and the stylus head 32 will be driven to slide downward through the fixed seat 3 25. When the stylus head 32 descends, the fixed seat 3 25 will also drive the extrusion plate 26 to slide downward. After the detection is completed, the inner slider 24 can drive the fixed seat 3 25 to rise, and cause the extrusion plate 26 and the stylus head 32 to rise.

[0051] like Figure 7 and Fig. 9 As shown, the interior of the fixing seat 3 25 is slidably connected with an electric slider 36 , the fixing plate 31 is fixedly connected between the two electric sliders 36 , and the length of the fixing seat 3 25 is the same as the length of the optical glass 3 .

[0052] During operation: when the multiple stylus heads 32 descend and touch the surface of the optical glass 3 for detection, the electric slider 36 can slide in the inner wall of the fixed seat 3 25, and cooperate with the multiple stylus heads 32 to achieve the effect of roughness detection of all positions on the surface of the optical glass 3.

[0053] like Figure 1 and Fig. 9 As shown, the top of the contact pin head 32 is fixedly connected with a plug rod 33, which is plugged into the fixed plate 31, and the top of the plug rod 33 is fixedly connected with a touch head 34. A pressure spring 35 is arranged on the outside of the plug rod 33, and the two ends of the pressure spring 35 are respectively fixedly connected to the bottom of the touch head 34 and the top of the fixed plate 31. A pressure test plate 30 is arranged above the touch head 34, and a connecting frame 29 is fixedly connected to the outside of the pressure test plate 30. The connecting frame 29 is fixedly installed on the top of the fixing seat 25. The surface area of ​​the pressure test plate 30 is the same as the surface area of ​​the optical glass 3 and they are kept parallel. A display panel 37 is arranged above the base plate 1.

[0054] During operation: when multiple stylus heads 32 touch the surface of the optical glass 3, the fixing plate 31 continues to drop a certain distance. At this time, each touch head 34 touches the pressure test plate 30 to apply pressure to various positions of the pressure test plate 30. When the stylus head 32 touches various convex positions on the surface of the optical glass 3, the touch head 34 connected thereto will apply greater pressure to the corresponding positions of the pressure test plate 30. When the stylus head 32 touches various smooth positions of the optical glass 3, the touch head 34 connected thereto will apply pressure to the corresponding positions of the pressure test plate 30 at normal values ​​and they are all equal. When the stylus head 32 touches various concave positions on the surface of the optical glass 3, the touch head 34 connected thereto will apply pressure to the corresponding positions of the pressure test plate 30 at normal values ​​and they are all equal. The pressure at the corresponding position of the pressure test plate 30 is relatively small, and the display panel 37 is used to display the distribution diagram of the pressure at each position of the pressure test plate 30, so as to facilitate the judgment of the distribution of the roughness of the optical glass 3. Through the fine contact of each stylus head 32 with the surface of the optical glass 3, the slight undulations of the surface, including convex surfaces, concave surfaces and smooth surfaces, can be accurately captured. The display panel 37 can display the pressure distribution diagram of each position of the pressure test plate 30 in real time. This intuitive graphical representation allows the inspection personnel to quickly identify the distribution of the surface roughness. Since the surface area of ​​the pressure test plate 30 is the same as that of the optical glass 3 and they remain parallel, the roughness of the entire surface can be fully covered and evaluated.
