Description

Technical Field

[0001] The present invention relates to the technical field of optical lens alignment, and particularly to an optical lens auxiliary alignment device. Background Art

[0002] At present, optical lenses are widely used in many fields such as photography and videography, medical equipment, semiconductor manufacturing, aerospace, etc. Their alignment accuracy plays a decisive role in the performance of the optical system.

[0003] However, there are many problems to be solved in the traditional optical lens alignment technology. For example: Most of the existing clamping methods simply rely on fixtures for fixation, which are difficult to adapt to optical lenses of different specifications. Moreover, during the alignment process, the lens is easily displaced or shaken due to external force interference. For example, during the alignment of some high-precision microscope lenses, a slight shake will cause a change in the relative position between the lenses, seriously affecting the imaging quality of the lens, making the observed image blurred and distorted, and unable to meet the requirements for high-definition imaging in scientific research and medical fields; at the same time, the method of manually adjusting the accuracy of optical lenses is inefficient and inaccurate. The alignment personnel operate based on experience and simple tools, and it is difficult to precisely control the position and angle of the lenses. In the alignment of complex multi-lens lenses, manual adjustment is prone to error accumulation, resulting in problems such as aberration and distortion of the lens that cannot be effectively corrected. Taking high-end photographic lenses as an example, aberration and distortion will cause the photographed photos to have problems such as blurred edges and image deformation, reducing the optical performance and usability of the lens; the traditional alignment accuracy detection methods are not precise enough to timely and accurately feedback the problems in the alignment process. Some simple detection tools can only perform rough measurements and are difficult to detect subtle optical deviations. This leads to the need for multiple rework adjustments after the lens assembly is completed, which not only increases the production cost but also prolongs the production cycle and affects the market competitiveness of the enterprise. Therefore, there is an urgent need for an optical lens auxiliary alignment device to solve the above problems. Summary of the Invention

[0018] Through the above technical solutions, the horizontal displacement of the second motor and the fixed pipe is realized, so that the toothed ring plate is accurately meshed with the outer wall of the optical lens body, preparing for the subsequent adjustment of the lens precision by the rotating assembly, and ensuring the accuracy and efficiency of the adjustment process.

[0019] The present invention is further configured such that the detection assembly includes a laser interferometer fixedly connected to the frame. The laser interferometer is located at the central position inside the mounting and adjusting table. A light-transmitting plate is arranged in the middle of the table board.

[0020] Through the above technical solutions, by analyzing the characteristics such as the shape and spacing of these interference fringes, the mounting and adjusting precision of the lens can be accurately detected, whether it meets the design requirements can be judged, a quantitative basis for the mounting and adjusting precision can be provided, and the imaging quality of the lens can be guaranteed.

[0021] The present invention is further configured such that a second helical gear is fixedly connected to the circumferential outer wall of the fourth rotating column. A first helical gear is meshed with the circumferential outer wall of the second helical gear. A fifth rotating column is fixedly connected to the circumferential inner wall of the first helical gear. A second transmission wheel is fixedly connected to the circumferential outer wall of the fifth rotating column. A vertical plate for ensuring the stable rotation of the fifth rotating column is fixedly connected to the bottom of the frame. A transmission belt is connected to the circumferential outer wall of the second transmission wheel. The second transmission wheel is connected to a first transmission wheel through the transmission belt. A first through groove is formed in one side of the frame. The transmission belt passes through the inside of the first through groove.

[0022] Through the above technical solutions, the transmission and conversion of power are realized, providing a power source for the dust removal assembly, and at the same time assisting other actions in the mounting and adjusting process to a certain extent, enhancing the overall coordination of the device.

[0023] The present invention is further configured such that the dust removal assembly includes a dust suction pipe fixedly connected to the circumferential outer wall of the assembly and adjustment table. One side of the dust suction pipe is rotatably connected to a first rotating column. The end of the first rotating column extending outside the dust suction pipe is fixedly connected to a first transmission wheel. The end of the dust suction pipe is provided with exhaust holes distributed at equal intervals. The circumferential outer wall of the first rotating column is fixedly connected with a shaft sleeve, and the circumferential outer wall of the shaft sleeve is fixedly connected with an impeller. The top of the table board is provided with negative pressure holes distributed at equal intervals in a circular shape for preliminarily adsorbing and fixing the optical lens body.

[0024] Through the above technical solutions: on the one hand, the optical lens body is adsorbed through the negative pressure holes to enhance the clamping stability. On the other hand, dust and other impurities around the assembly and adjustment table are sucked in and discharged through the exhaust holes, reducing the interference of dust on the laser propagation, preventing dust from adhering to the lens and optical elements, and ensuring that the laser interferometer can accurately detect the assembly and adjustment accuracy of the lens.

[0025] The beneficial effects of the present invention are as follows: The optical lens auxiliary assembly and adjustment device realizes the stable clamping of the optical lens by the coordinated operation of the clamping assembly and the power assembly. When the first motor is started, the moving gear drives the fixed cover to rotate, so that the sliding column slides in the second limiting groove, pushing the movable rod and the clamping ring plate to clamp the lens, completing the fixation in the horizontal direction. At the same time, the fourth rotating column drives the second gear disk, so that the second threaded screw rotates, and the second threaded sleeve rises to drive the pressing pipe to descend, pressing the lens from the vertical direction through the pressing plate and the rubber sleeve. The multi-directional fixation effectively avoids the shaking of the lens during assembly and adjustment, providing a stable basis for the subsequent assembly and adjustment work.

[0026] The optical lens auxiliary assembly and adjustment device realizes the efficient and precise adjustment of the optical lens through the mutual cooperation of the power assembly and the rotating assembly. When the first motor operates, the second threaded screw rotates to drive the first helical gear disk, and through the second helical gear disk, the first threaded screw rotates, thereby enabling the horizontal displacement of the second motor and the fixed pipe. The toothed ring plate meshes with the outer wall of the lens. When the second motor is started, it drives the fixed pipe to rotate, realizing the simultaneous adjustment of multiple lenses of the lens. Compared with the traditional assembly and adjustment method, the assembly and adjustment efficiency is greatly improved.

[0027] The optical lens auxiliary assembly and adjustment device, during the process of assembling and adjusting the optical lens body, can accurately detect the assembly and adjustment accuracy of the optical lens by using a laser interferometer. At the same time, the laser interferometer is fixed at the central position inside the assembly and adjustment table, and the light-transmitting plate in the middle of the table board facilitates the laser to pass through. The laser forms interference fringes after being reflected or refracted by the lens. By analyzing the characteristics such as the shape and spacing of the fringes, it can be judged whether the assembly and adjustment of the lens meet the design requirements, providing a quantitative basis for the assembly and adjustment accuracy and ensuring the imaging quality of the lens.

[0028] The optical lens auxiliary alignment device effectively optimizes the detection environment through the dust removal component, improving the detection accuracy. As the first motor continues to operate, it drives a series of transmission structures to rotate the impeller, generating suction in the suction pipe. On the one hand, it adsorbs the lens through the negative pressure holes, enhancing the clamping stability. On the other hand, it sucks in the dust around the alignment table and discharges it through the exhaust holes, reducing the interference of dust on laser propagation, preventing dust from adhering to the lens and optical components, and ensuring the accurate and reliable detection results of the laser interferometer.

A plurality of toothed ring plates 17 are arranged on the circumferential outer wall of the fixed pipe 14, and the plurality of toothed ring plates 17 are meshed with the outer wall of the optical lens body 2; A chassis 3 is fixedly connected to the bottom of the frame 1, and a power assembly for providing clamping driving force for the clamping assembly is arranged on the top of the chassis 3; The circumferential motion of the power assembly can drive the rotating assembly to horizontally displace and quickly cooperate with the optical lens body 2; A detection assembly for testing the assembly accuracy of the optical lens body 2 is arranged inside the assembly and adjustment table 12; A dust removal assembly for improving the detection accuracy of the detection assembly is arranged on one side of the assembly and adjustment table 12. In this assembly device, through the close cooperation of each component, a series of functions from fixing to adjusting, detecting and environmental optimization in the process of optical lens assembly are realized. At the same time, the frame 1 serves as a basic support structure to carry and stabilize the whole device, and the assembly and adjustment table 12 is fixed on one side of the frame 1 to provide an operation platform for the assembly of the optical lens body 2. The clamping assembly, rotating assembly, power assembly, detection assembly and dust removal assembly cooperate with each other to ensure the efficient and accurate progress of the assembly work and improve the quality and efficiency of optical lens assembly.

[0034] Specifically, the clamping assembly includes a rotating ring seat 59 fixedly connected to the circumferential inner wall of the assembly and adjustment table 12. A fixed cover 49 is rotatably connected inside the rotating ring seat 59. A second limiting groove 60 is formed in the top outer wall of the fixed cover 49 and is equidistantly and circularly distributed. A sliding column 58 is slidably connected inside the second limiting groove 60. Both ends of the sliding column 58 pass through the inside of the second limiting groove 60. The cross section of the second limiting groove 60 is arc-shaped. One end of the sliding column 58 is fixedly connected to a movable rod 35, and the other end of the movable rod 35 is fixedly connected to a clamping ring plate 34 for clamping the optical lens body 2. A first limiting groove 36 is formed in the top of the table board 11, and the movable rod 35 is slidably connected to the first limiting groove 36. In the clamping assembly, the rotating ring seat 59 is fixed to the circumferential inner wall of the assembly and adjustment table 12. There are equidistantly circularly distributed second limiting grooves 60 on the top of the fixed cover 49 rotatably connected inside it. The sliding column 58 slides in the second limiting groove 60, one end is connected to the movable rod 35, and the other end of the movable rod 35 is connected to the clamping ring plate 34. The first limiting groove 36 on the top of the table board 11 restricts the movement track of the movable rod 35. When the fixed cover 49 rotates, the sliding column 58 slides along the second limiting groove 60, driving the movable rod 35 to slide in the first limiting groove 36, so that the clamping ring plate 34 moves towards the center, thereby stably clamping the horizontal direction of the optical lens body 2 and preventing the lens from having horizontal displacement during assembly, providing a stable basis for subsequent operations.

[0035] Specifically, the power assembly includes a fixed seat 4 fixedly connected to the chassis 3. The inner circumferential wall of the fixed seat 4 is fixedly connected with a first motor 5. The output end of the first motor 5 is fixedly connected with a fourth rotating column 39. One end of the fourth rotating column 39 is fixedly connected with a moving gear 47. Below the fixed cover 49, there is a gear ring frame 48 fixedly connected thereto. The moving gear 47 meshes with the gear ring frame 48. In the power assembly, since the fixed seat 4 is fixed on the chassis 3, the output end of the internal first motor 5 is connected to the fourth rotating column 39. The moving gear 47 at one end of the fourth rotating column 39 meshes with the gear ring frame 48 below the fixed cover 49. When the first motor 5 is started, the power is transmitted to the moving gear 47 through the fourth rotating column 39, driving the fixed cover 49 to rotate, providing a stable clamping driving force for the clamping assembly, ensuring that the clamping ring plate 34 tightly clamps the optical lens body 2, and guaranteeing the stability and reliability of the clamping process.

The outer circumferential wall of the second threaded lead screw 27 is threadedly connected with a second threaded sleeve 30. The top of the second threaded sleeve 30 is fixedly connected with a fixing plate 29. The fixing plate 29 is fixedly connected with a pressing tube 37 for vertically pressing and fixing the optical lens body 2. When the fourth rotating column 39 rotates, it drives the second gear disk 55 to rotate, thereby causing the first gear disk 54 to rotate. The third rotating column 28 rotates accordingly, the second threaded lead screw 27 rotates, and the second threaded sleeve 30 rises, driving the pressing tube 37 to descend, using the pressing plate 51 and the rubber sleeve 52 to press the optical lens body 2 vertically. In cooperation with the horizontal clamping of the clamping ring plate 34, multi-directional stable fixation of the optical lens body 2 is achieved, further enhancing the clamping effect and effectively avoiding lens shaking during installation and adjustment.

[0037] Specifically, the inner circumferential wall of the pressing tube 37 is fixedly connected with a pressing plate 51. Below the pressing plate 51, there is a rubber sleeve 52 for preventing clamping and damaging the optical lens body 2. The rubber sleeve 52 is adhesively bonded to the inner circumferential wall of the pressing tube 37. When the pressing tube 37 presses the optical lens body 2, the rubber sleeve 52 plays a buffering role, preventing the pressing tube 37 from directly contacting the lens and causing clamping damage, protecting the surface and structural integrity of the optical lens body 2, and ensuring that the lens is not damaged during installation and adjustment.

When the second threaded lead screw 27 rotates to drive the second threaded sleeve 30 to rise or fall, through the cooperation of the cross column 53 and the slider 20, the second threaded sleeve 30 is ensured to move smoothly, its movement direction is restricted, the stability of the whole device when fixing the lens in the vertical direction is enhanced, and at the same time, the second threaded sleeve 30 is prevented from shifting or shaking during the movement process.

[0039] Specifically, a first bevel gear disc 22 is fixedly connected to the top of the second threaded lead screw 27. A second bevel gear disc 23 is meshed with the circumferential outer wall of the first bevel gear disc 22. A first housing 16 is fixedly connected to the top of the frame 1.

The end of the connecting column 25 passing through the inside of the third through groove 26 is fixedly connected to the second motor 38. When the second threaded lead screw 27 rotates, it drives the first bevel gear disc 22 to rotate, and then the second bevel gear disc 23 rotates. The first threaded lead screw 21 rotates accordingly. The first threaded sleeve 24 drives the connecting column 25 to move, realizing the horizontal displacement of the second motor 38 and the fixed tube 14, so that the toothed ring plate 17 is accurately meshed with the outer wall of the optical lens body 2, preparing for the subsequent adjustment of the lens precision by the rotating assembly, and ensuring the accuracy and efficiency of the adjustment process.

[0040] Specifically, the detection assembly includes a laser interferometer 46 fixedly connected to the frame 1. The laser interferometer 46 is located at the central position inside the mounting and adjustment table 12. A light-transmitting plate 33 is arranged in the middle of the table board 11. During the mounting and adjustment process of the optical lens body 2, the laser interferometer 46 emits laser light. The laser light passes through the light-transmitting plate 33 and forms interference fringes after being reflected or refracted by the optical lens body 2. By analyzing the characteristics such as the shape and spacing of these interference fringes, the mounting and adjustment precision of the lens can be accurately detected, and it can be judged whether it meets the design requirements, providing a quantitative basis for the mounting and adjustment precision and ensuring the imaging quality of the lens.

[0041] Specifically, a second helical gear 57 is fixedly connected to the circumferential outer wall of the fourth rotating column 39. The first helical gear 56 meshes with the circumferential outer wall of the second helical gear 57. A fifth rotating column 45 is fixedly connected to the circumferential inner wall of the first helical gear 56. A second transmission wheel 43 is fixedly connected to the circumferential outer wall of the fifth rotating column 45. A vertical plate 44 for ensuring the stable rotation of the fifth rotating column 45 is fixedly connected to the bottom of the frame 1. The circumferential outer wall of the second transmission wheel 43 is drivingly connected to a transmission belt 8. The second transmission wheel 43 is drivingly connected to a first transmission wheel 7 through the transmission belt 8. A first through groove 6 is formed in one side of the frame 1, and the transmission belt 8 passes through the inside of the first through groove 6. When the first motor 5 operates, the fourth rotating column 39 drives the second helical gear 57 to rotate, thereby causing the first helical gear 56 to rotate, the fifth rotating column 45 to rotate, and the second transmission wheel 43 to rotate accordingly. The first transmission wheel 7 is driven to rotate through the transmission belt 8. This series of transmission structures realizes the transmission and conversion of power, provides a power source for the dust removal assembly, and at the same time assists other actions during the installation and adjustment process to a certain extent, enhancing the overall coordination of the device.

[0042] Specifically, the dust removal assembly includes a dust suction pipe 13 fixedly connected to the circumferential outer wall of the installation and adjustment table 12. A first rotating column 10 is rotatably connected to one side of the dust suction pipe 13. The end of the first rotating column 10 extending outside the dust suction pipe 13 is fixedly connected to the first transmission wheel 7. A plurality of exhaust holes 41 are formed at equal intervals at one end of the dust suction pipe 13. A sleeve is fixedly connected to the circumferential outer wall of the first rotating column 10, and an impeller 42 is fixedly connected to the circumferential outer wall of the sleeve. A plurality of negative pressure holes 32 for preliminarily adsorbing and fixing the optical lens body 2 are formed at equal intervals in a circular distribution on the top of the table board 11. When the first transmission wheel 7 rotates, it can drive the first rotating column 10 to rotate, so that the impeller 42 rotates to generate suction. In this operation, on the one hand, the optical lens body 2 is adsorbed through the negative pressure holes 32 to enhance the clamping stability. On the other hand, dust and other impurities around the installation and adjustment table 12 are sucked in and discharged through the exhaust holes 41, reducing the interference of dust on the laser propagation, preventing dust from adhering to the lens and optical elements, and ensuring that the laser interferometer 46 can accurately detect the installation and adjustment accuracy of the lens.

[0043] Working principle: When the staff needs to adjust the optical lens body 2, it can be first placed on the platen 11, and then the first motor 5 is started. The output end of the first motor drives the fourth rotating column 39 to rotate. When the fourth rotating column 39 rotates, the moving gear 47 rotates accordingly. Since the moving gear 47 meshes with the gear ring frame 48 under the fixed cover 49, the fixed cover 49 can be driven to rotate within the rotating ring seat 59. The sliding column 58 in the second limiting groove 60 at the top of the fixed cover 49 will slide along the arc groove due to the rotation of the fixed cover 49, driving the movable rod 35 to slide within the first limiting groove 36, causing the clamping ring plate 34 to move towards the center to clamp the optical lens body 2, achieving the clamping and fixing of the optical lens body 2 in the horizontal direction before adjustment, ensuring the stable progress of the subsequent adjustment work of the optical lens body 2. During this process, the fourth rotating column 39 drives the second gear disk 55 to rotate, which meshes with the first gear disk 54, causing the third rotating column 28 to rotate, and the second threaded lead screw 27 rotates accordingly. The second threaded sleeve 30 rises under its action, driving the pressure tube 37 to descend, and pressing the lens from the vertical direction by using the pressing plate 51 and the rubber sleeve 52, achieving the clamping and fixing of the optical lens body 2 in the vertical direction, thereby being able to cooperate with the horizontal clamping of the clamping ring plate 34 to achieve the multi-directional fixation of the optical lens body 2, effectively avoiding the shaking of the optical lens body 2 during adjustment; At the same time, during the rotation of the second threaded lead screw 27, the first helical gear disk 22 rotates accordingly, meshing with the second helical gear disk 23, causing the first threaded lead screw 21 to rotate. The first threaded sleeve 24 drives the connecting column 25 to move, and the second motor 38 and the fixed tube 14 move horizontally accordingly. The toothed ring plate 17 meshes with the outer wall of the optical lens body 2. After the second motor 38 is started, the second rotating column 15 drives the fixed tube 14 to rotate, thereby realizing the simultaneous adjustment of multiple lenses of the optical lens body 2, improving the adjustment efficiency of the optical lens body 2. As the first motor 5 continues to operate, the fourth rotating column 39 drives the second helical gear 57 to rotate, meshing with the first helical gear 56, causing the fifth rotating column 45 to rotate, and the second transmission wheel 43 rotates accordingly. Through the transmission belt 8, the first transmission wheel 7 is driven to rotate, and the first rotating column 10 rotates accordingly, causing the impeller 42 in the dust suction tube 13 to rotate to generate suction, adsorbing the lens through the negative pressure holes 32 to ensure stable clamping. At the same time, the rotation of the impeller 42 causes the dust suction tube 13 to generate suction, and dust and other impurities around the adjustment table 12 are sucked in and discharged through the exhaust holes 41. The dust suction process reduces the interference of dust on laser propagation, avoids dust adhering to the lens and optical components, affecting the detection accuracy, and ensures that the laser interferometer 46 can accurately detect the adjustment accuracy of the lens; During the alignment process of the optical lens body 2, the laser interferometer 46 is fixed on the frame 1 and located at the central position inside the alignment table 12. The light-transmitting plate 33 in the middle of the platen 11 facilitates the passage of laser. When the laser interferometer 46 emits laser, interference fringes are formed after being reflected or refracted by the optical lens body 2. By analyzing the characteristics such as the shape and spacing of the interference fringes, the alignment accuracy of the lens is detected to determine whether it meets the design requirements, thus realizing the detection of the alignment accuracy of the optical lens body 2.
