Description

Technical Field

[0001] The present invention relates to the technical field of optical equipment, and in particular to a high-precision optical lens rapid switching system. Background Art

[0002] Optical lens switching systems play a vital role in optical devices, especially in scenarios where lenses need to be quickly adjusted according to different optical requirements, such as microscopes, laser equipment, photographic lenses, etc. Traditional optical lens switching systems usually achieve lens switching through mechanical structures, but these systems have some significant technical bottlenecks.

[0003] First, the traditional optical lens switching system usually uses a rotating frame or a sliding mechanism to achieve the switching of lenses. For example, the prior art (publication number: CN116500742A) discloses an optical lens switching mechanism, which drives the rotating frame to rotate around the bearing by a motor to achieve the switching of lenses. However, this design has obvious limitations: the rotation angle is usually limited to ±90°, resulting in only two different lenses being switched, and the scope of application is limited. In addition, after the rotating frame is switched multiple times, the limiting device (such as the limiting pressure ring and the limiting lever) is prone to wear and deformation, resulting in a slight deflection of the lens after switching, affecting the optical imaging quality.

[0004] Secondly, in the traditional optical lens switching system, the lens often moves with the rotating frame or sliding mechanism during the switching process, resulting in an unstable optical path. Especially in high-precision optical equipment, the slight displacement of the lens will have a significant impact on the refraction and reflection of light, thereby affecting the clarity and accuracy of the image. In addition, the switching speed of the traditional system is slow and cannot meet the demand for fast response of modern optical equipment.

[0005] Finally, the traditional optical lens switching system also has shortcomings in the addition and removal of lenses and angle adjustment. The addition and removal of lenses usually requires manual operation, which increases the complexity and time cost of the operation. The angle adjustment of the lens relies on a complex mechanical structure, which not only increases the complexity of the system, but also reduces the reliability and service life of the system.

[0006] To sum up, the existing optical lens switching system has many shortcomings in terms of switching accuracy, switching speed, lens addition and reduction, and angle adjustment. There is an urgent need for a new optical lens switching system that can achieve high-precision, fast switching, flexible addition and reduction of lenses, and support angle adjustment. Summary of the invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0008] Therefore, the object of the present invention is to provide a high-precision optical lens fast switching system, comprising a housing with light entry holes and light exit holes respectively opened on both sides thereof, a housing, a switching mechanism arranged inside the housing,

[0009] The switching mechanism includes a fixed bar, two movable bars symmetrically arranged about the fixed bar, and a third reflector and a fourth reflector located on both sides of the fixed bar, wherein the fixed bar and the movable bar are movably connected.

[0010] The fixing bar is movably connected with a first rotating ring, in which a first lens is arranged, and the movable bar is movably connected with a second rotating ring, in which a second lens is arranged.

[0011] The third reflector and the fourth reflector are fixed on both sides of the movable frame, and the top surface of the fixed bar is sequentially provided with a first mounting bar and a second mounting bar, the first mounting bar is provided with a first driving mechanism for driving the first rotating ring to rotate, and the second mounting bar is provided with a second driving mechanism for driving the movable frame to reciprocate horizontally.

[0012] As the preferred technical solution:

[0013] According to the high-precision optical lens fast switching system as described above, the inner wall of the shell is fixed with a first reflector, a second reflector, a fifth reflector and a sixth reflector through a column, the first reflector and the second reflector have opposite inclined surfaces, the second reflector and the third reflector have opposite inclined surfaces, the third reflector and the fourth reflector have opposite inclined surfaces, the fourth reflector and the fifth reflector have opposite inclined surfaces, and the fifth reflector and the sixth reflector have opposite inclined surfaces.

[0014] The first reflector, the second reflector, the third reflector, the fourth reflector, the fifth reflector and the sixth reflector have the same structure. The first reflector is a triangular prism structure, and a reflective lens is arranged on the inclined surface of the first reflector.

[0015] Through the above technical solution, after the light enters the shell through the light entrance hole, it will be reflected to the second reflector through the reflective lens on the first reflector, and then reflected to the third reflector through the reflective lens on the second reflector. And so on, the light will be reflected to the sixth reflector through the fourth reflector and the fifth reflector, and finally emitted from the light exit hole through the reflective lens on the sixth reflector. Several reflectors cooperate with each other to set the path of the light.

[0016] In the high-precision optical lens fast switching system as described above, the fixing bar is a hollow structure, the top of the fixing bar is open, and the top surface of the fixing bar is welded and fixed to the bottom end of the first mounting bar.

[0017] On both side walls of the fixed strip, there are first through holes for the first rotating ring to penetrate. The inner wall of the first through hole is in bearing connection with the outer circular wall of the first rotating ring. A first sprocket is sleeved on the outer circular wall of the first rotating ring.

[0018] The first driving mechanism includes a driving roller and a driven roller. The two ends of the driving roller and the driven roller are in bearing connection with the inner wall of the first mounting strip. The first mounting strip is of a hollow structure, and the bottom end of the first mounting strip is open.

[0019] Second sprockets are fixed on the driving roller and the driven roller by snap pins. One end of the driving roller is butted against a first motor, and the first motor is fixed on the side wall of the first mounting strip.

[0020] A transmission chain meshing with the second sprocket is sleeved on the second sprocket, and the transmission sprocket meshes with the first sprocket.

When the second sprocket rotates, the first sprocket can be driven to rotate synchronously through the transmission chain. A tensioning wheel is also arranged inside the first mounting strip, so that the transmission chain can be in a tensioned state, thereby ensuring the overall transmission effect.

[0022] In a high-precision optical lens quick-switching system as described above, a cross groove is opened on the top surface of the housing. A top cover is fixed in the cross groove by bolts. A group of vertical plates are welded and fixed to the bottom surface of the top cover. The two ends of the first mounting strip and the second mounting strip are welded and fixed to the vertical plates.

[0023] The second mounting strip is of a hollow shape, and the top end of the second mounting strip is open. The bottom surface of the second mounting strip is welded and fixed to the top surface of the first mounting strip.

[0024] The second driving mechanism includes a lead screw and a movable block located inside the second mounting strip. The lead screw penetrates through the movable block and is in threaded connection with the movable block. A group of guide rods penetrate through the movable block. The top end of the movable block is welded and fixed to a movable frame, and the movable frame is in an inverted "U" shape as a whole.

[0025] Both ends of the lead screw penetrate through the second mounting strip and are in bearing connection with the vertical plates. One end of the lead screw is butted against a second motor, and the second motor is fixed on the vertical plate. Both ends of the guide rod are welded and fixed to the vertical plate.

[0026] Through the above technical solution, when maintenance of the switching mechanism is required, the top cover can be removed, and the movable frame can be moved into the cross groove. Then, the top cover is lifted upward, and through the two vertical plates, the fixed strip, the movable strip, the first mounting strip and the second mounting strip can be taken out of the housing, and the operation is simple and convenient.

[0027] In the high-precision optical lens fast switching system as described above, the movable bar is provided with a second through hole for the second rotating ring to penetrate, and the outer circular wall of the second rotating ring is movably connected to the inner wall bearing of the second through hole.

[0028] The first rotating ring has first magnet blocks embedded in both sides, the second rotating ring has second magnet blocks embedded in the top surface, and the side surface of the first magnet block and the top surface of the second magnet block have opposite magnetic poles.

[0029] Through the above technical solution, the first magnet block and the second magnet block are preferably circular or arc-shaped, and there are multiple first magnet blocks and second magnet blocks distributed in a ring shape. When the first rotating ring rotates to any angle and the second rotating ring is fitted with the first rotating ring, the first magnet block and the second magnet block on the two will partially overlap, and then through the magnetic adsorption effect, the first rotating ring can drive the second rotating ring to rotate synchronously when it rotates.

[0030] According to the high-precision optical lens quick switching system described above, a group of first fixed tubes are fixed to both side corners of the bottom end of the fixed bar, and a group of second fixed tubes are fixed to both side corners of the two movable bars close to the fixed bar, and a rotating rod is inserted into the first fixed tube and the second fixed tube.

[0031] The rotating rod is connected to the first fixed tube bearing, the rotating rod is fixedly connected to the second fixed tube, both ends of the two rotating rods are connected to the vertical plate bearings, one end of the two rotating rods is respectively connected to the third motor and the fourth motor, the third motor and the fourth motor are bolted to the vertical plate,

[0032] The two vertical plates are parallel to each other, one of the vertical plates is provided with a through slot, a plurality of ceramic sleeves penetrate the vertical plate at the through slot, a first conductive column is bonded to the ceramic sleeve, and the plurality of first conductive columns are respectively connected to the first motor, the second motor, the third motor and the fourth motor with electric wires,

[0033] The bottom end of the first conductive column is connected to the second conductive column, the second conductive column is fixed on a fixing frame made of ceramic material, a plurality of the second conductive columns are connected to the power grid through wires, and the fixing frame is fixedly bonded to the inner wall of the shell.

[0034] Through the above technical solution, the opening and closing of the first motor, the second motor, the third motor and the fourth motor can be controlled by an external control switch, so as to realize the switching, stacking and rotation of the lens, and because the vertical plate will be moved out of the shell at the same time when the switching mechanism is taken out, the conductive structure formed by the first conductive column and the second conductive column will not hinder the removal of the switching mechanism, and the structure is reasonable.

[0035] Compared with the prior art, the present invention has at least the following beneficial effects:

[0036] (1) The present invention realizes the versatility and high-precision control of lens switching through the coordinated work of the horizontal movement adjustment system of the third reflector and the fourth reflector and the rotation stacking system of the movable bar. The third reflector and the fourth reflector adjust the light path by horizontal movement to guide the light to different lenses, thereby realizing fast switching. During the switching process, the lenses remain stable and avoid displacement, ensuring high-precision switching and thus ensuring imaging quality. In addition, the third reflector and the fourth reflector can switch multiple lenses at the same time by linear movement, which has a wider applicability. The light path is precisely adjusted so that the light can be quickly switched to different lenses (the first lens or the second lens). At the same time, the movable bar is rotated to fit with the fixed bar so that the first lens and the second lens are stacked, realizing flexible increase or decrease in the number of lenses. The coordinated work of these two systems not only improves the speed and accuracy of lens switching, but also expands the function of the system so that the increase or decrease of lenses and the adjustment of the light path can be carried out synchronously.

[0037] (2) The present invention realizes rapid switching of lenses and precise control of the optical path through the coordinated work of the first driving mechanism and the second driving mechanism. The first driving mechanism drives the first rotating ring to rotate through chain transmission (first sprocket, second sprocket and transmission chain) to achieve angle adjustment of the lens; the second driving mechanism drives the movable frame to move horizontally through the cooperation of the screw rod and the movable block to achieve precise displacement of the third reflector and the fourth reflector. This driving method not only improves the switching speed, but also ensures the stability and reliability of the system, and avoids the wear and deformation problems of traditional mechanical structures.

DETAILED DESCRIPTION

[0047] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0049] like Figure 1-Figure 2 As shown, an embodiment of the present invention discloses a high-precision optical lens fast switching system, wherein light entrance holes and light exit holes are respectively opened on both sides of a shell 1, a switching mechanism is arranged inside the shell 1, and a first reflector 2, a second reflector 3, a fifth reflector 6 and a sixth reflector 7 are fixed to the inner wall of the shell 1 through columns, the oblique surfaces of the first reflector 2 and the second reflector 3 are opposite to each other, the oblique surfaces of the second reflector 3 and the third reflector 4 are opposite to each other, the oblique surfaces of the third reflector 4 and the fourth reflector 5 are opposite to each other, the oblique surfaces of the fourth reflector 5 and the fifth reflector 6 are opposite to each other, and the oblique surfaces of the fifth reflector 6 and the sixth reflector 7 are opposite to each other, the first reflector 2, the second reflector 3, the third reflector 4, the fourth reflector 5, the fifth reflector 6 and the sixth reflector 7 are opposite to each other, the first reflector 2, the second reflector 3, the third reflector 4, the fourth reflector 5, the fifth reflector 6 and the sixth reflector 7 have the same structure, the first reflector 2 is a triangular prism structure, and a reflective lens is arranged on the oblique surface of the first reflector 2.

[0050] The switching mechanism includes a fixed bar 8, two movable bars 11 symmetrically arranged about the fixed bar 8, and a third reflector 4 and a fourth reflector 5 located on both sides of the fixed bar 8. The fixed bar 8 and the movable bar 11 are movably connected.

[0051] A first rotating ring 9 is movably connected to the fixed bar 8 , and a first lens 10 is disposed inside the first rotating ring 9 . A second rotating ring 12 is movably connected to the movable bar 11 , and a second lens 13 is disposed inside the second rotating ring 12 .

[0052] The third reflector 4 and the fourth reflector 5 are fixed on both sides of the movable frame 26. The top surface of the fixed bar 8 is provided with a first mounting bar 16 and a second mounting bar 17 in sequence. The first mounting bar 16 is provided with a first driving mechanism for driving the first rotating ring 9 to rotate, and the second mounting bar 17 is provided with a second driving mechanism for driving the movable frame 26 to reciprocate horizontally.

[0053] After the light enters the shell 1 through the light entrance hole, it passes through the reflective lenses on the first reflector 2, the second reflector 3, the third reflector 4, the fourth reflector 5, the fifth reflector 6 and the sixth reflector 7. The path of the light will continue to change after being refracted. Finally, the light is emitted through the light exit hole. When the light is reflected by the third reflector 4 to the fourth reflector 5, the light will pass through the first lens 10 on the fixing bar 8.

[0054] When the first driving mechanism is driven, it will drive the first rotating ring 9 to rotate, thereby realizing the self-rotation of the first lens 10. When the number of the first lenses 10 needs to be increased, the movable bar 11 can be fitted with the fixed bar 8 by rotating, and the first rotating ring 9 and the second rotating ring 12 on the two are aligned, so that the first lens 10 and the second lens 13 are stacked on each other, and the number of lenses is increased. When the number of lenses needs to be reduced, the movable bar 11 only needs to be rotated and reset.

[0055] When the second driving mechanism is running, it will drive the movable frame 26 to move, and the movable frame 26 will drive the third reflector 4 and the fourth reflector 5 to move synchronously. When the third reflector 4 and the fourth reflector 5 move, the path of the light will change, so that the light can pass through different first lenses 10. In this way, rapid switching of lenses can be achieved.

[0056] The number and size of the first lenses 10 on the fixed bar 8 and the second lenses 13 on the movable bar 11 are consistent, and the types of the multiple first lenses 10 on the fixed bar 8 are different, and the types of the multiple second lenses 13 on the movable bar 11 are also different. In this way, by switching different lenses, it can be applied to different scenes.

[0057] like Figure 2 As shown, a group of first fixed tubes 28 are fixed to both side corners of the bottom end of the fixed bar 8, and a group of second fixed tubes 29 are fixed to both side corners of the two movable bars 11 close to the fixed bar 8, and a rotating rod 27 is inserted into the first fixed tube 28 and the second fixed tube 29.

[0058] The rotating rod 27 is bearing-connected to the first fixed tube 28 , and the rotating rod 27 is fixedly connected to the second fixed tube 29 . Both ends of the two rotating rods 27 are bearing-connected to the vertical plate 18 . One end of the two rotating rods 27 is respectively connected to the third motor and the fourth motor, and the third motor and the fourth motor are bolted to the vertical plate 18 .

[0059] When the number of lenses needs to be increased, the third motor or the fourth motor can be driven to operate. After the third motor or the fourth motor is running, the rotating rod 27 can be driven to rotate axially on the first fixed cylinder 28. The rotating rod 27 drives the movable bar 11 to rotate through the second fixed cylinder 29, so that the movable bar 11 is fitted with the fixed bar 8. When the movable bar 11 is fitted with the fixed bar 8, the first lens 10 and the second lens 13 are aligned and stacked with each other, thereby increasing the number of lenses. The third motor or the fourth motor can be both forward and reverse. When the number of lenses needs to be reduced, the third motor or the fourth motor can be driven to reverse and reset the movable bar 11.

[0060] like Figure 2 , Figure 3 and Figure 4 As shown, the fixing bar 8 is a hollow structure, the top of the fixing bar 8 is open, the top surface of the fixing bar 8 is welded and fixed to the bottom end of the first mounting bar 16, and the two side walls of the fixing bar 8 are provided with first through holes for the first rotating ring 9 to penetrate, the outer circular wall of the first rotating ring 9 is movably connected to the inner wall bearing of the first through hole, and the outer circular wall of the first rotating ring 9 is sleeved with a first sprocket 21.

[0061] The first driving mechanism includes an active roller and a driven roller, both ends of which are connected to the inner wall bearings of the first mounting bar 16. The first mounting bar 16 is a hollow structure, and the bottom end of the first mounting bar 16 is open. The active roller and the driven roller are both fixed with a second sprocket 22 by a bayonet. One end of the active roller is connected to the first motor, which is fixed to the side wall of the first mounting bar 16. The second sprocket 22 is sleeved with a transmission chain meshing with it, and the transmission sprocket is meshed with the first sprocket 21.

[0062] A second through hole is provided on the movable bar 11 for the second rotating ring 12 to pass through. The outer circular wall of the second rotating ring 12 is movably connected to the inner wall bearing of the second through hole. First magnet blocks 14 are embedded on both sides of the first rotating ring 9, and a second magnet block 15 is embedded on the top surface of the second rotating ring 12. The side surface of the first magnet block 14 and the top surface of the second magnet block 15 are opposite magnetic poles.

[0063] The open end of the fixed strip 8 corresponds to the open end of the first mounting strip 16, so that the internal spaces of the two can communicate with each other. Furthermore, the drive sprocket can rotate inside the two. When the angle of the lens needs to be adjusted, the first motor can be driven to operate. The first motor drives the active roller to rotate axially. The second sprockets 22 on the active roller and the driven roller cooperate with each other to drive the drive sprocket to start rotating. The drive sprocket drives the first rotating ring 9 to rotate in the first through hole through the first sprocket 21, and the first rotating ring 9 can drive the first lens 10 inside it to rotate.

[0064] When the movable strip 11 rotates towards the fixed strip 8 and fits with the fixed strip 8, at this time, the second rotating ring 12 is aligned and fitted with the first rotating ring 9. The second magnet block 15 on the top surface of the second rotating ring 12 will fit with the first magnet block 14 on the side surface of the first rotating ring 9. The second magnet block 15 and the first magnet block 14 attract each other. Under the action of magnetic force, when the first rotating ring 9 rotates, it will also drive the second rotating ring 12 to rotate synchronously in the second through hole. Furthermore, when the first lens 10 works in cooperation with the second lens 13, the first lens 10 and the second lens 13 can also be driven to rotate synchronously.

[0065] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, the second mounting strip 17 is hollow, the top end of the second mounting strip 17 is open, and the bottom surface of the second mounting strip 17 is welded and fixed to the top surface of the first mounting strip 16.

[0066] The second driving mechanism includes a lead screw 23 and a movable block 25 located inside the second mounting strip 17. The lead screw 23 passes through the movable block 25 and is threadedly connected to the movable block 25. A set of guide rods 24 penetrate through the movable block 25. The top end of the movable block 25 is welded and fixed to the movable frame 26. The movable frame 26 is in an inverted "U" shape as a whole. Both ends of the lead screw 23 penetrate through the second mounting strip 17 and are connected to the vertical plate 18 by bearings. One end of the lead screw 23 is docked with the second motor, the second motor is fixed on the vertical plate 18, and both ends of the guide rod 24 are welded and fixed to the vertical plate 18.

[0067] When it is necessary to switch the lens, the second motor can be driven to operate, and the second motor drives the screw rod 23 to rotate axially on the second mounting strip 17. The screw rod 23 can drive the movable block 25 to move linearly along the guide rod 24 by rotating, and the movable block 25 can drive the movable frame 26 to move synchronously, and then the movable frame 26 can drive the third reflector 4 and the fourth reflector 5 to move. After the third reflector 4 and the fourth reflector 5 move, the path of the light will be changed, and the light can pass through different first lenses 10. When the light passes through the appropriate first lens 10, the second motor is stopped. The lens switching can be achieved in the above manner; the second motor can rotate forward and reverse, and continuous switching can be achieved by forward and reverse rotation. In order to improve the switching accuracy, a high-precision model can be selected for the screw rod 23.

[0068] like Figure 2 , Figure 6 and Figure 7 As shown, a cross slot 20 is provided on the top surface of the shell 1, a top cover 19 is fixed with bolts in the cross slot 20, a group of vertical plates 18 are welded and fixed to the bottom surface of the top cover 19, both ends of the first mounting bar 16 and the second mounting bar 17 are welded and fixed to the vertical plates 18, the two vertical plates 18 are parallel to each other, a through slot 30 is provided on one of the vertical plates 18, a plurality of ceramic sleeves penetrate the vertical plate 18 at the through slot 30, a first conductive column 31 is bonded to the ceramic sleeve, and the plurality of first conductive columns 31 are respectively connected to the first motor, the second motor, the third motor and the fourth motor with electric wires.

[0069] The bottom end of the first conductive column 31 is connected to the second conductive column 32 . The second conductive column 32 is fixed on a fixing frame 33 made of ceramic material. A plurality of second conductive columns 32 are connected to the power grid through wires. The fixing frame 33 is fixedly bonded to the inner wall of the housing 1 .

[0070] Before operation, when the switching mechanism is placed into the shell 1 through the cross slot 20, the top cover 19 is then installed in the cross slot 20. At this time, the vertical plate 18 on one side cooperates with the fixing frame 33, and the vertical plate 18 is connected to the first conductive column 31 and the second conductive column 32 on the fixing frame 33. In this way, the first motor, the second motor, the third motor and the fourth motor can be connected to the power grid through the first conductive column 31 and the second conductive column 32, and the first motor, the second motor, the third motor and the fourth motor can be driven to operate through the external control switch.
