Description

Technical Field

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

[0002] Optical lens switching systems play a crucial role in optical devices, especially in scenarios where lenses need to be quickly adjusted according to different optical requirements, such as microscopes, laser devices, 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 of all, traditional optical lens switching systems usually adopt a rotating frame or a sliding mechanism to achieve lens switching. For example, the prior art (publication number: CN116500742A) discloses an optical lens switching mechanism that drives a rotating frame to rotate around a bearing through a motor to achieve lens switching. However, this design has obvious limitations: the rotation angle is usually limited between ±90°, resulting in only two different lenses being able to be switched, with a limited scope of application. In addition, after multiple switchings, the limiting devices (such as limiting retaining rings and limiting lever) of the rotating frame are prone to wear and deformation, resulting in slight deflection of the lens after switching, affecting the optical imaging quality.

[0004] Secondly, during the switching process of traditional optical lens switching systems, the lens often undergoes displacement along with the rotating frame or the sliding mechanism, resulting in unstable optical paths. Especially in high-precision optical devices, even a tiny displacement of the lens will have a significant impact on the refraction and reflection of light, thereby affecting the clarity and accuracy of imaging. In addition, the switching speed of traditional systems is relatively slow and cannot meet the requirements of modern optical devices for rapid response.

[0005] Finally, traditional optical lens switching systems also have deficiencies in terms of lens addition and subtraction and angle adjustment. The addition and subtraction of lenses usually require manual operation, increasing the complexity and time cost of operation. And the angle adjustment of the lens depends on complex mechanical structures, which not only increases the complexity of the system but also reduces the reliability and service life of the system.

[0006] In summary, the existing optical lens switching systems have many deficiencies in terms of switching accuracy, switching speed, lens addition and subtraction, and angle adjustment. There is an urgent need for a new type of optical lens switching system that can achieve high precision, rapid switching, flexible lens addition and subtraction, 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 technologies.

[0008] Therefore, the object of the present invention is to provide a high-precision optical lens rapid switching system, including a housing with a light incident hole and a light exit hole respectively opened on both sides of the housing, including a housing, and a switching mechanism is arranged inside the housing.

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

[0010] A first rotating ring is movably connected to the fixed bar, a first lens is arranged inside the first rotating ring, a second rotating ring is movably connected to the movable bar, and a second lens is arranged inside the second rotating ring.

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

[0012] As a preferred technical solution:

[0013] In the high-precision optical lens rapid switching system as described above, a first reflector, a second reflector, a fifth reflector and a sixth reflector are fixed to the inner wall of the housing through columns. The inclined surfaces of the first reflector and the second reflector face each other, the inclined surfaces of the second reflector and the third reflector face each other, the inclined surfaces of the third reflector and the fourth reflector face each other, the inclined surfaces of the fourth reflector and the fifth reflector face each other, and the inclined surfaces of the fifth reflector and the sixth reflector face each other.

[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 of a triangular prism structure, and a reflecting lens is arranged on the inclined surface of the first reflector.

[0015] Through the above technical solution, after the light enters the housing through the light incident hole, it will be reflected by the reflecting lens on the first reflector to the second reflector, and then reflected by the reflecting lens on the second reflector to the third reflector, and so on. The light will be reflected to the sixth reflector through the fourth reflector and the fifth reflector, and finally exit from the light exit hole through the reflecting lens on the sixth reflector. The several reflectors cooperate with each other to set the path of the light.

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

[0017] Both side walls of the fixed strip are provided with first through holes for the first rotating ring to penetrate. The outer circumferential wall of the first rotating ring is in bearing connection with the inner wall of the first through hole, and a first sprocket is sleeved on the outer circumferential wall of the first rotating ring.

[0018] The first driving mechanism includes a driving roller and a driven roller. Both 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.

[0021] Through the above technical solution, the first sprocket, the second sprocket and the transmission chain are combined into a chain drive structure. 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 by bolts in the cross groove, a group of vertical plates are welded and fixed to the bottom surface of the top cover, and both 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 hollow, the top end of the second mounting strip is open, and 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 in 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, and the top end of the movable block is welded and fixed to a movable frame. 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 needs to be performed on the switching mechanism, the top cover can be removed, the movable frame can be moved into the cross groove, and then the top cover can be lifted upward. 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] A high-precision optical lens quick-switching system as described above, a second through-hole for the second rotating ring to penetrate is formed on the movable bar, and the outer circumferential wall of the second rotating ring is movably connected to the inner wall of the second through-hole by a bearing.

[0028] On both sides of the first rotating ring, first magnet blocks are embedded, and on the top surface of the second rotating ring, second magnet blocks are embedded. The side surface of the first magnet block and the top surface of the second magnet block are 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 a plurality of the first magnet blocks and the second magnet blocks are distributed in a ring shape. When the first rotating ring rotates by any angle and the second rotating ring fits with the first rotating ring, some of the first magnet blocks and the second magnet blocks on both of them will overlap. Then, through the magnetic adsorption effect, when the first rotating ring rotates, it can drive the second rotating ring to rotate synchronously.

[0030] A high-precision optical lens quick-switching system as described above, a set of first fixing cylinders are fixed at both bottom corners on both sides of the fixed bar, and a set of second fixing cylinders are fixed at the side corners of the two movable bars close to the fixed bar. A rotating rod is inserted into the first fixing cylinder and the second fixing cylinder.

[0031] The rotating rod is connected to the first fixing cylinder by a bearing, the rotating rod is fixedly connected to the second fixing cylinder, both ends of the two rotating rods are connected to the vertical plate by bearings, and one end of each of the two rotating rods is respectively butted with a third motor and a 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. A through groove is formed on one of the vertical plates, and a plurality of ceramic sleeves penetrate through the vertical plate at the through groove. The ceramic sleeves are bonded with first conductive columns, and the plurality of first conductive columns are respectively electrically connected to the first motor, the second motor, the third motor, and the fourth motor by wires.

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

[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 through an external control switch, so as to realize the switching, stacking, and rotating actions of the lenses. And since when the switching mechanism is taken out, the vertical plate will be simultaneously removed from the housing, 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 achieves versatility and high-precision control of lens switching through the coordinated operation 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, guiding the light to different lenses, thereby achieving rapid switching. During the switching process, the lenses remain stable and avoid displacement, ensuring high-precision switching and thus guaranteeing imaging quality. In addition, the third reflector and the fourth reflector can switch multiple lenses simultaneously through 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 fitted with the fixed bar by rotation, so that the first lens and the second lens are stacked, realizing flexible increase or decrease in the number of lenses. The coordinated operation 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 achieves rapid lens switching and precise control of the optical path through the coordinated operation of a first drive mechanism and a second drive mechanism. The first drive mechanism drives the first rotating ring to rotate through a chain drive (a first sprocket, a second sprocket, and a drive chain) to achieve lens angle adjustment; the second drive mechanism drives the movable frame to move horizontally through the cooperation of a screw rod and a movable block to achieve precise displacement of the third and fourth reflectors. This drive method not only improves switching speed but also ensures the stability and reliability of the system, avoiding the wear and deformation problems of traditional mechanical structures.

Detailed implementation manners

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

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

[0049] As Figure 1 - Figure 2 shown, the embodiment of the present invention discloses a high-precision optical lens rapid switching system. Light incident holes and light exit holes are respectively provided on both sides of the housing 1. A switching mechanism is arranged inside the housing 1. The first reflector 2, the second reflector 3, the fifth reflector 6 and the sixth reflector 7 are fixed to the inner wall of the housing 1 through columns. The inclined surfaces of the first reflector 2 and the second reflector 3 face each other, the inclined surfaces of the second reflector 3 and the third reflector 4 face each other, the inclined surfaces of the third reflector 4 and the fourth reflector 5 face each other, the inclined surfaces of the fourth reflector 5 and the fifth reflector 6 face each other, and the inclined surfaces of the fifth reflector 6 and the sixth reflector 7 face 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 of a triangular prism structure, and a reflecting lens is arranged on the inclined surface of the first reflector 2.

[0050] The switching mechanism includes a fixing strip 8, two movable strips 11 symmetrically arranged with respect to the fixing strip 8, and the third reflector 4 and the fourth reflector 5 located on both sides of the fixing strip 8. The fixing strip 8 and the movable strip 11 are movably connected.

[0051] A first rotating ring 9 is movably connected to the fixing bar 8, a first lens 10 is arranged 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 arranged inside the second rotating ring 12.

[0052] The third reflector 4 and the fourth reflector 5 are fixed to both sides of the movable frame 26. The top surface of the fixing bar 8 is sequentially provided with a first mounting bar 16 and a second mounting bar 17. A first driving mechanism for driving the first rotating ring 9 to rotate is arranged inside the first mounting bar 16, and a second driving mechanism for driving the movable frame 26 to move horizontally back and forth is arranged inside the second mounting bar 17.

[0053] After the light enters the housing 1 through the light incident hole, through the reflecting 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 change continuously after being refracted. Finally, the light exits 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 rotated to fit the fixing bar 8, and the first rotating ring 9 and the second rotating ring 12 on both of them are aligned. In this way, the first lens 10 and the second lens 13 are stacked on each other, realizing the increase in the number of lenses. When the number needs to be reduced, only the movable bar 11 needs to be rotated back to its original position.

[0055] When the second driving mechanism operates, it will drive the movable frame 26 to move. 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, the rapid switching of the lenses is realized.

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

[0057] As Figure 2 shown, a set of first fixing cylinders 28 are fixed to both bottom corners on both sides of the fixing bar 8, and a set of second fixing cylinders 29 are fixed to both side corners of the two movable bars 11 close to the fixing bar 8. A rotating rod 27 is inserted into the first fixing cylinders 28 and the second fixing cylinders 29.

[0058] The rotating rod 27 is connected to the first fixed cylinder 28 by bearings. The rotating rod 27 is fixedly connected to the second fixed cylinder 29. Both ends of the two rotating rods 27 are connected to the vertical plate 18 by bearings. One end of each of the two rotating rods 27 is respectively butted with a third motor and a fourth motor. 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 operates, it can drive the rotating rod 27 to axially rotate on the first fixed cylinder 28. The rotating rod 27 drives the movable strip 11 to rotate through the second fixed cylinder 29, so that the movable strip 11 fits with the fixed strip 8. When the movable strip 11 fits with the fixed strip 8, the first lens 10 and the second lens 13 are aligned and stacked with each other, thereby realizing an increase in the number of lenses. Both the third motor and the fourth motor can rotate forward and backward. When the number of lenses needs to be decreased, driving the third motor or the fourth motor to reverse can drive the movable strip 11 to reset.

[0060] As Figure 2 、 Figure 3 and Figure 4 shown, the fixed strip 8 is a hollow structure. The top end of the fixed strip 8 is open. The top surface of the fixed strip 8 is welded and fixed to the bottom end of the first mounting strip 16. First through holes for the first rotating ring 9 to penetrate are provided on both side walls of the fixed strip 8. The outer circumferential wall of the first rotating ring 9 is in bearing movable connection with the inner wall of the first through hole. A first sprocket 21 is sleeved on the outer circumferential wall of the first rotating ring 9.

[0061] The first driving mechanism includes a driving roller and a driven roller. Both ends of the driving roller and the driven roller are connected to the inner wall of the first mounting strip 16 by bearings. The first mounting strip 16 is a hollow structure. The bottom end of the first mounting strip 16 is open. Second sprockets 22 are fixed on the driving roller and the driven roller by snap pins. One end of the driving roller is butted with a first motor. The first motor is fixed on the side wall of the first mounting strip 16. A transmission chain meshing with the second sprocket 22 is sleeved on the second sprocket 22. The transmission sprocket meshes with the first sprocket 21.

[0062] Second through holes for the second rotating ring 12 to penetrate are provided on the movable strip 11. The outer circumferential wall of the second rotating ring 12 is in bearing movable connection with the inner wall of the second through hole. First magnet blocks 14 are embedded on both sides of the first rotating ring 9. 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 bar 8 corresponds to the open end of the first mounting bar 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 bar 11 rotates towards the fixed bar 8 and fits with the fixed bar 8, at this time the second rotating ring 12 aligns and fits 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 the 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 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 bar 17 is hollow, the top end of the second mounting bar 17 is open, and the bottom surface of the second mounting bar 17 is welded and fixed to the top surface of the first mounting bar 16.

[0066] The second driving mechanism includes a lead screw 23 and a movable block 25 located inside the second mounting bar 17. The lead screw 23 passes through the movable block 25 and is threadedly connected to the movable block 25. A group 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 bar 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 the lens needs to be switched, the second motor can be driven to operate. The second motor drives the lead screw 23 to rotate axially on the second mounting strip 17. The lead screw 23 can drive the movable block 25 to move linearly along the guide rod 24 through rotation. The movable block 25 can drive the movable frame 26 to move synchronously. Furthermore, 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 light path will be changed. Thus, the light can pass through different first lenses 10. When the light passes through the appropriate first lens 10, the operation of the second motor is stopped. The switching of the lens can be achieved in the above way; the second motor can rotate forward and backward, and continuous switching can be realized through forward and backward rotation. In order to improve the switching accuracy, a high-precision model can be selected for the lead screw 23.

[0068] As Figure 2 , Figure 6 and Figure 7 shown, a cross groove 20 is formed in the top surface of the housing 1. The top cover 19 is bolted and fixed in the cross groove 20. A group of vertical plates 18 are welded and fixed to the bottom surface of the top cover 19. The two ends of the first mounting strip 16 and the second mounting strip 17 are welded and fixed to the vertical plates 18. The two vertical plates 18 are parallel to each other. A through groove 30 is formed in one of the vertical plates 18. A plurality of ceramic sleeves penetrate through the vertical plate 18 at the through groove 30. The first conductive posts 31 are bonded to the ceramic sleeves. The plurality of first conductive posts 31 are respectively electrically connected to the first motor, the second motor, the third motor and the fourth motor by wires.

[0069] The bottom end of the first conductive post 31 is butted against the second conductive post 32. The second conductive post 32 is fixed on the fixing frame 33 made of ceramic material. The plurality of second conductive posts 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 the operation, when the switching mechanism is placed into the housing 1 through the cross groove 20, then the top cover 19 is installed in the cross groove 20. At this time, one side of the vertical plate 18 is matched with the fixing frame 33, and the first conductive posts 31 and the second conductive posts 32 on the vertical plate 18 and the fixing frame 33 are butted against each other. 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 posts 31 and the second conductive posts 32. The first motor, the second motor, the third motor and the fourth motor can be driven to operate through an external control switch.
