Description

Technical Field

[0001] The invention belongs to the field of optical element processing, and in particular relates to a device for processing the surface roughness of an optical element. Background Art

[0002] The processing flow of surface roughness treatment of optical components includes preliminary grinding - fine grinding - polishing - cleaning - coating. After the initial grinding is completed, the value of the lens curvature radius is determined and impurities on the surface are removed. Fine grinding can further reduce the roughness of the lens and make the lens surface more regular, laying a good foundation for later polishing.

[0003] During the polishing process, the polishing time, pressure and other parameter values ​​must be determined. The polishing operation can make the appearance of the optical lens delicate and smooth, greatly reducing the roughness of the lens surface. It is a key step in making the lens surface reach the required smoothness.

[0004] According to the needs, optical lenses need to be processed into different curvatures. Some optical instruments need to use convex mirrors, some need to use concave mirrors, and some need flat mirrors (such as mobile phone screens). The polishing methods generally used for optical lenses can only polish one type of lens. For example, classical polishing can only process convex mirrors but not concave mirror surfaces. Moreover, during classical polishing, the normal component of the working pressure on the polishing surface is uneven, and it changes with the change of the swing amplitude of the ejector pin. Assuming the working pressure is P and the normal component of the polishing surface is F, then: F = P·cosa. It is precisely because of this pressure distribution characteristic that the aperture control of classical polishing is more difficult. In addition, some other polishing inventions cannot achieve surface roughness processing of concave or convex mirrors with different curvatures. Summary of the invention

[0005] In view of the above technical problems, the present invention provides a device that can perform uniform force treatment on the surface roughness of optical lenses such as flat mirrors and concave mirrors and convex mirrors with different curvatures.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] (1) The present invention can process the surface roughness of a convex mirror or a concave mirror by switching the first positioning seat and the second positioning seat to be fixedly connected to the workbench, and can process the surface of a flat mirror by telescoping the telescopic adjustment mechanism. The same device can process a variety of different types of optical lenses, and has diverse functions;

[0009] (ii) According to the different curvatures of the convex mirror or concave mirror, the surface roughness of the convex mirror or concave mirror with different curvatures can be processed by adjusting the position of the slide seat on the swing rod. The swing amplitude of the swing rod can be changed by changing the position of the adjustment block. The swing amplitude of the swing rod can be adjusted according to the outer diameter of the convex mirror or concave mirror; optical lenses of different specifications can be processed;

[0010] (3) The preset polishing pressure is applied by the second electric push rod, and the second electric push rod is always in the normal position of the optical lens during the swinging process, so that the force of fine grinding and polishing of the optical lens is more uniform, avoiding the problem of difficult aperture control.

DETAILED DESCRIPTION

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0029] Reference Figure 1-14As shown, the present invention includes a workbench 1, on which a driving motor 2, a driving rod 3, and a swing rod 4 are provided. The driving rod 3 is fixedly connected to the driving motor 2, the upper end of the swing rod 4 is rotatably connected to a first positioning seat 5, and the lower end of the swing rod 4 is rotatably connected to a second positioning seat 6. A vertically arranged driving groove 7 is provided in the middle of the swing rod 4, and one of the first positioning seat 5 and the second positioning seat 6 can be switched to be fixedly connected to the workbench 1, and an adjusting block 8 with an adjustable distance between the driving rod 3 and its rotation axis is provided, and a round rod 9 that can slide in the driving groove 7 is rotatably connected to the adjusting block 8. The rocker arm 4 is fixedly connected to a mounting seat 10, and a height-adjustable slide seat 11 is provided on the mounting seat 10, a support rod 12 and a telescopic adjustment mechanism 13 are hinged on the slide seat 11, an end of the support rod 12 away from the slide seat 11 is hinged to a fixed seat 14, the telescopic end of the telescopic adjustment mechanism 13 is hinged to the fixed seat 14, a detachable polishing disc 15 is fixedly connected to the fixed seat 14, and a lifting and lowering adjustable support plate 16 is provided on the workbench 1, a turntable 17 is rotatably connected to the support plate 16, and a detachable optical lens 18 is fixedly connected to the turntable 17.

[0030] The present invention provides a device for processing the surface roughness of optical lenses such as flat mirrors and concave and convex mirrors with different curvatures. The specific implementation is as follows:

[0031] (a) Grinding and polishing of convex mirrors: Figure 4 , Figure 6 , Figure 7 As shown, when the convex mirror is subjected to surface treatment, the second positioning seat 6 is fixedly connected to the workbench 1, and the first positioning seat 5 is separated from the workbench 1. At this time, the swing rod 4 can rotate and swing around the fixed axis of the second positioning seat 6;

[0032] (ii) Grinding and polishing of concave mirrors: Figure 5 , Figure 6 , Figure 7 As shown, when the concave mirror is subjected to surface treatment, the first positioning seat 5 is fixedly connected to the workbench, and the second positioning seat 6 is separated from the workbench 1. At this time, the swing rod 4 can rotate and swing around the fixed axis of the first positioning seat 5;

[0033] The polishing disc 15 reciprocates along the arc surface formed by the longitudinal section of the convex / concave mirror, and cooperates with the rotation of the convex / concave mirror, so that each point on the spherical upper surface of the convex / concave mirror can be evenly subjected to force and finely polished, and the surface roughness is better processed, with high precision and high yield rate;

[0034] According to the pre-processed curvature radius of the convex / concave mirror, the swing radius of the polishing disk 15 is adjusted by adjusting the position of the slide 11, wherein the lower end surface of the polishing disk 15 is provided with a curved surface with the same curvature as the convex / concave mirror, so that the polishing contact surface with the convex / concave mirror is larger, thereby improving the polishing efficiency. When the position adjustment of the slide 11 is locked, the convex / concave mirror is fixed to the turntable 17, and then the height of the support plate 16 is adjusted so that the convex / concave mirror contacts the polishing disk 15 and a certain pressure is preset. In the initial state, the driving rod 3, the rocker arm 4, and the polishing disk 15 are all vertically arranged. When the driving motor 2 is started to drive the driving rod 3 to rotate, the round rod 9 on the adjustment block 8 slides in the driving groove 7 and drives the rocker arm 4 to swing back and forth. According to the size of the convex / concave mirror, the position of the adjustment block 8 can be changed, thereby changing the swing amplitude of the rocker arm 4. The position of the adjustment block 8 can be changed by driving the lead screw through a servo motor, and the lead screw rotatably connected to the rocker arm 4 is threadedly connected to the adjustment block 8 to achieve the change of the position of the adjustment block 8.

[0035] (III) Grinding and polishing of flat mirrors: Figure 6 As shown, when processing the surface of the flat mirror, no matter which one of the first positioning seat 5 or the second positioning seat 6 is fixedly connected to the workbench 1, when the driving motor 2 is not started, the swing rod 4 and the mounting seat 10 are at the initial position and stationary, then, the support plate 16 is raised so that the optical lens 18 on the turntable 17 contacts the polishing disc 15 and a certain pressure is preset, then, the turntable 17 rotates, and the support rod 12 swings to polish the flat mirror, wherein the telescopic adjustment mechanism 13 uses an electric push rod, and the outer diameter of the polishing disc 17 is larger than the outer diameter of the optical lens 18;

[0036] The optical lens is fixed on the turntable, and can be fixed by a rubber ring, adhesive fixation or clamping fixation;

[0037] In addition, in order to ensure that the optical lens is subjected to uniform force during polishing, an electric push rod is fixedly connected between the fixed seat 14 and the polishing disk 15. The preset pressure between the optical lens 18 and the polishing disk 15 is set by the electric push rod. If the preset force is given by a vertically moving turntable, the force is vertical. When the polishing disk 15 is not in a vertical state, it is subjected to a component of the vertical pressure, resulting in uneven force. If the force is given by the electric push rod, the electric push rod is always in the normal direction of the optical lens, the optical lens is subjected to uniform force, and the contraction of the electric push rod facilitates the replacement operation of the polishing disk 15.

[0038] like Figure 7As shown, in order to achieve better switching positioning of the rocker arm 4, the workbench 1 is provided with a first arc groove 19 and a second arc groove 20, the center of the first arc groove 19 coincides with the axis center of the second positioning seat 6 in the fixed position, and the center of the second arc groove 20 coincides with the axis center of the first positioning seat 5 in the fixed position, and the first positioning seat 5 is fixedly connected with a first limiting shaft 21, and the first limiting shaft 21 is fixedly connected with a first slider that can slide along the first arc groove 19, and the second positioning seat 6 is fixedly connected with a second limiting shaft 22, and the second limiting shaft 22 is fixedly connected with a second slider that can slide along the second arc groove 20, and the workbench 1 is vertically slidably connected with a first positioning frame 23, and the first positioning frame 23 moves downward to cooperate with the first positioning seat 5 to lock it, and the first positioning frame 23 moves upward to cooperate with the second positioning seat 6 to lock it.

[0039] The cooperation between the first arc groove 19 and the first limit shaft 21 and the first slider, as well as the cooperation between the second arc groove 20 and the second limit shaft 22 and the second slider can support and guide the rocker arm 4, and when the first positioning seat 5 and the second positioning seat 6 are switched to be fixedly connected with the workbench 1, the positioning can be achieved more smoothly.

[0040] Specifically, the first fixing method: Fig.10 As shown, the first positioning seat 5 and the second positioning seat 6 are made of iron material, the upper end of the first positioning frame 23 is fixedly connected to the first electromagnet 24 that cooperates with the first positioning seat 5, and the lower end of the first positioning frame 5 is fixedly connected to the second electromagnet 25 that cooperates with the second positioning seat 6.

[0041] An electromagnet is a device that generates electromagnetism when powered on. It is a non-permanent magnet. The strength of the magnetic field generated by the electromagnet is related to the magnitude of direct current. The greater the current, the stronger the magnetism. The magnitude of the magnetism can be controlled by changing the resistance to control the magnitude of the current. Therefore, when the first positioning seat 5 needs to be fixed, the first electromagnet 24 is powered on, the second electromagnet is powered off, and the first positioning frame 23 moves downward. When the second positioning seat 6 needs to be fixed, the first electromagnet 24 is powered off, the second electromagnet is powered on, and the first positioning frame 23 moves upward. When the electromagnet attracts and fixes the first positioning seat 5 or the second positioning seat 6, in order to prevent the fixed position of the first positioning seat 5 or the second positioning seat 6 from shifting when the swing rod 4 swings and affecting the polishing effect, a larger current is required to fix the first positioning seat 5 or the second positioning seat 6 more firmly.

[0042] The second fixing method: Fig. 9 As shown, the upper end of the first positioning seat 5 is provided with a first positioning hole 26, the lower end of the second positioning seat 6 is provided with a second positioning hole, the upper end of the first positioning frame 23 is provided with a first limiting column 27 that cooperates with the first positioning hole 26, and the lower end of the first positioning frame 5 is provided with a second limiting column that cooperates with the second positioning hole.

[0043] When the first positioning seat 5 needs to be positioned, the first positioning frame 23 moves downward, and the first limiting column 27 enters the first positioning hole 26. Only when the first limiting column 27 enters the first positioning hole 26 can the second limiting column 27 be detached from the second positioning hole; similarly, when the second positioning seat 6 needs to be positioned, the first positioning frame 23 moves upward, and the second limiting column enters the second positioning hole. Only when the second limiting column enters the second positioning hole can the first limiting column 27 be detached from the first positioning hole 26; this fixing method does not require power supply.

[0044] The third fixing method: Fig.11 As shown, the above two methods are combined, that is, through the two methods of electromagnet attraction and the positioning hole cooperation of the limit column, the first positioning seat 5 or the second positioning seat 6 is fixed more stably.

[0045] Specifically, in order to realize the vertical movement and locking of the first positioning frame 23, a first rack 61 is fixedly connected to the first positioning frame 23, the first rack 61 is meshed with a pinion 28 rotatably connected to the workbench 1, the pinion 28 is coaxially fixedly connected with a first worm gear 29, and the first worm gear 29 is meshed with a first worm 30 fixedly connected to the workbench 1.

[0046] The first worm wheel 29 and the first worm 30 constitute a worm gear mechanism. When the first worm 30 is driven to rotate, the first worm 30 drives the first worm wheel 29 meshing therewith to rotate, and the first worm wheel 29 drives the pinion 28 fixedly connected thereto to rotate. When the pinion 28 rotates, it drives the first positioning frame 23 to move up and down through the first rack 61 meshing therewith. The worm gear mechanism has self-locking properties, and when the first positioning frame 23 moves upward to the highest point or downward to the lowest point, it can be locked.

[0047] Furthermore, in order to improve the stability of fixation, the other end of the first limit shaft 21 is fixedly connected to a first limit block 31, the other end of the second limit shaft 22 is fixedly connected to a second limit block 32, the lower end of the first limit block 31 is provided with a third limit hole, the upper end of the second limit block 32 is provided with a fourth limit hole, and a second positioning frame 33 is vertically slidably connected to the workbench 1, the upper end of the second positioning frame 33 is fixedly connected to a third limit column 34 corresponding to the third limit hole, the lower end of the second positioning frame 33 is fixedly connected to a fourth limit column 35 corresponding to the fourth limit hole, and the second positioning frame 33 is fixedly connected to a second rack 36 meshing with the pinion 28.

[0048] In this embodiment, a second positioning frame 33 having the same function as the first positioning frame 23 is added. The first positioning frame 23 and the second positioning frame 33 have a gear rack structure to simultaneously drive opposite or opposite movements, thereby achieving more fixed points, making the swing rod 4 more stable when swinging.

[0049] like Fig.12 As shown, in order to realize that the turntable can be adjusted in height synchronously with the slide and can rotate to drive the optical element for surface treatment, the workbench 1 is fixedly connected with a first servo motor 37 and a second servo motor 38, the output end of the first servo motor 37 is fixedly connected with a vertically arranged driving shaft 39, and the driving shaft 39 is vertically slidably connected with a first pulley 40, the lower end of the turntable 17 is fixedly connected with a rotating shaft 41, the rotating shaft 41 downwardly penetrates the support plate 16 and is fixedly connected with a second pulley 42, the first pulley 40 and the second pulley are rotatably connected to the workbench 1, the first pulley 40 and the second pulley 42 are connected by a transmission belt 43, and the output end of the second servo motor 38 is fixedly connected with a vertically arranged lifting screw 44, and the lifting screw 44 is threadedly connected to the support plate 16.

[0050] The lifting screw 44 and the support plate 16 form a screw nut structure. When the second servo motor 38 starts to drive the lifting screw 44 to rotate, it will drive the support plate 16 to rise and fall. When the support plate 16 is raised and lowered, the first pulley 40 slides vertically on the drive shaft 39. When the support plate 16 is adjusted to the required height, it is locked through the screw nut structure. At this time, the first servo motor 37 is started, and the drive shaft 39 and the first pulley 40 are matched by vertically arranged limit pins and limit grooves. When the first servo motor 37 starts to drive the drive shaft 39 to rotate, it will drive the first pulley 40 to rotate through the limit pins and limit grooves. The first pulley 40 drives the second pulley 42 to rotate through the transmission belt 43, thereby realizing the rotation of the turntable 17 at different heights.

[0051] In order to improve the coating effect of the optical element during coating; a second worm wheel 45 and a second worm 46 meshing with each other are rotatably connected in the fixed seat 14, a vibration seat 47 is provided below the second worm 46, the second worm 46 and the vibration seat 47 are connected by a spline, a limiting ring groove 48 is provided on the vibration seat 47, two left-right symmetrical rollers are rollingly connected in the limiting ring groove 48, a vibration fork 49 is hinged in the fixed seat 14, the two rollers are rotatably connected to the vibration fork 49, the second worm wheel 45 is coaxially fixedly connected with an eccentric wheel 50, a driven ring sleeve 51 is sleeved on the eccentric wheel 50, a connecting rod 52 is fixedly connected to the driven ring sleeve 51, and the connecting rod 52 is hinged to the vibration fork 50 at one end away from the driven ring sleeve 51.

[0052] When the surface roughness of the optical element is qualified and cleaned, it needs to be coated. When coating the optical element, the polishing disk is replaced with a coating disk, and the second worm 46 is driven to rotate by the motor. The second worm 46 drives the second worm wheel 45 meshing with it to rotate. At the same time, the second worm 46 drives the vibration seat 47 splined with it to rotate, and the second worm wheel 45 drives the eccentric wheel 50 coaxially fixedly connected with it to rotate. The eccentric wheel 50, the driven ring sleeve 51, the connecting rod 52 and the vibration fork 49 constitute a crank rocker mechanism. When the eccentric wheel 50 rotates, it will drive the vibration fork 49 to swing back and forth through the connecting rod 52. When the vibration fork 49 swings back and forth up and down, it will drive the vibration seat 47 to move up and down along the axial direction of the worm. Therefore, the coating disk can vibrate up and down while rotating.

[0053] In order to filter out larger impurities and avoid scratches on optical components, a receiving container 53 is fixedly connected to the support plate 16, the turntable 17 is in the receiving container 53, and a filter container 54 is fixedly connected to the workbench 1. A hose 55 is fixedly connected between the filter container 54 and the receiving container 53. A detachable filter screen is fixedly connected in the filter container 54 to divide the filter container 54 into an upper cavity and a lower cavity. The lower cavity is connected to a suction pump 56, and the outlet end of the suction pump 56 is connected to a nozzle 58 through a second hose 57. The nozzle 58 is above the optical lens 18.

[0054] Optical lens polishing requires the use of coolant, which helps to control the temperature during the processing of the optical lens and reduce deformation, cracks and other problems caused by overheating of the lens during the polishing process. It can also play a role in lubrication and flushing away debris generated by the processing, thereby ensuring the smooth progress of the polishing process. It would be very wasteful to use the coolant once. If it is recycled, if the debris generated by the processing is large and is brought to the surface of the optical lens, it will affect the polishing effect of the optical lens. Therefore, the coolant is recovered by using the receiving container 53, and the recovered coolant enters the upper cavity of the filter container 54 through the hose 55. The coolant entering the upper cavity is filtered through the filter and enters the lower cavity. Finally, the coolant in the lower cavity is pumped out by the suction pump 56 and sprayed onto the surface of the optical lens by the nozzle 58 through the second hose 57.

[0055] Among them, an adjustment mechanism is provided on the mounting base 10, and the adjustment mechanism includes a third servo motor 59. The output end of the third servo motor 59 is fixedly connected with an adjustment screw 60. The adjustment screw 60 rotatably connected to the mounting base 10 is threadedly connected to the slide 11. The adjustment screw 60 has the same pitch as the lifting screw 44. The third servo motor 59 rotates synchronously with the second servo motor 38.

[0056] The adjusting screw 60 rotatably connected to the mounting base 10 and the slide 11 form a screw nut structure. When the adjusting screw 60 is driven to rotate by the third servo motor 59, the slide 11 will slide on the mounting base 10 to adjust its position. When the position of the slide 11 is adjusted according to the curvature of the convex mirror or concave mirror, the position of the support plate 16 should also rise or fall accordingly. In order to achieve synchronous and unidirectional movement of the support plate 16 and the slide 11, the adjusting screw 60 and the lifting screw 44 have the same pitch and the same thread direction, and the third servo motor 59 and the second servo motor 38 rotate synchronously and in the same direction.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
