Description

Technical Field

[0001] This utility model relates to the field of optical instrument technology, specifically to an optical instrument lens assembly and positioning device. Background Technology

[0002] Optical lenses are essential components in machine vision systems, directly affecting image quality and the implementation and effectiveness of algorithms. Optical lenses can be categorized by focal length (short focal length, medium focal length, long focal length), field of view (wide-angle, standard, telephoto), and structure (fixed aperture prime lens, manual aperture prime lens, automatic aperture prime lens, manual zoom lens, automatic zoom lens, automatic aperture motorized zoom lens, motorized triple-variable zoom lens, etc.).

[0003] However, in the production and assembly process of optical lenses, the lens installation stage needs to rely on a special positioning device to ensure accuracy. For example, an optical instrument lens assembly positioning device with application number 202323136601.9. Although this utility model can achieve the positioning and assembly of optical instruments of different specifications through the coordinated design of guiding mechanism, lifting mechanism, locking part and ejector part, the device is simple to operate, has high positioning and assembly accuracy, and can significantly improve the work efficiency of engineers.

[0004] However, although its guide tube offers a variety of models to choose from, it can only install one lens at a time, and after installation, the assembled lens must be removed before the next operation can be carried out. This single-lens operation mode greatly restricts the improvement of overall installation efficiency. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This utility model provides an optical instrument lens assembly and positioning device, which has the following beneficial effects:

[0017] The lens mounting and positioning device for this optical instrument utilizes a first mounting groove with two layers of adjacent sections at a 90-degree angle within the mounting plate, and a first limiting component consisting of a first spring and a limiting post within the first mounting groove. Combined with a guide tube with an arc-shaped bottom, this device enables rapid adaptation to guide tubes of different diameters, secure engagement of the guide tube, and reduced installation difficulty. The cooperation of multiple placement posts on the bottom plate with corresponding placement tubes on the top plate, along with the conical grooves on the upper surface of the placement posts, allows for adaptation to different sized lens barrels, achieving initial positioning of the lens barrel and precise lens attachment. The combination of pressing the guide post, pressing the guide barrel, and the third spring ensures constraint on the top... The plate moves only vertically to avoid rotational deviation, thereby driving all placement tubes to move up and down synchronously. By pressing the second mounting groove in the guide barrel, the second spring, and the limiting hemispherical head, forming a second limiting component, together with the second limiting groove on the guide post, the position of the guide barrel can be locked after the top plate is pressed, preventing the device from resetting itself and ensuring stable lens assembly. Through the cooperation of multiple guide posts with the same diameter and corresponding guide tubes, it can support operators to simultaneously place lenses and remove all assembled lenses at once, ultimately significantly shortening the overall assembly cycle, improving assembly efficiency, and meeting the needs of mass production of lenses of various specifications.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: an optical instrument lens assembly and positioning device, including a support plate 1, a base plate 8 fixedly connected to the front end of the upper surface of the support plate 1, a plurality of placement columns 10 fixedly connected to the upper surface of the base plate 8, a placement tube 11 that can move up and down synchronously is sleeved on the top of each of the plurality of placement columns 10, and the placement tube 11 can slide up and down on the placement column 10, a placement plate 5 is provided directly above the placement tube 11, and a placement opening 7 is provided on the upper surface of the placement plate 5, and guide tubes 6 of different diameters can be clamped in the placement opening 7.

[0027] Please see Figures 1 to 2 A vertical support plate 2 is fixedly connected to the rear end of the upper surface of the support plate 1. A horizontal support plate 3 extending to the top of the top plate 9 is fixedly connected to the top end of the vertical support plate 2. A connecting post 4 is fixedly connected to the front end of the lower surface of the horizontal support plate 3. The bottom end of the connecting post 4 is fixedly connected to the placement plate 5. The axes of the placement plate 5 and the bottom plate 8 coincide and are on the same axis. Each placement port 7 has a first limiting component for stabilizing the guide tube 6 on its inner circumferential surface. At the same time, the bottom end of the guide tube 6 is designed to be arc-shaped. Therefore, when the guide tube 6 is inserted into the placement port 7 and is snapped in place by multiple limiting posts 14, its hemispherical bottom end can easily push the limiting post 14 into the first mounting groove 13 with the help of the guiding effect of the arc surface. The initial positioning of the guide tube can be completed without applying excessive external force.

[0028] Please see Figures 1 to 3 The first limiting component includes multiple first mounting grooves 13 formed on the inner circumferential surface of the placement port 7, and a limiting post 14 with one end exposed is slidably connected in the first mounting groove 13. A first spring 15 with one end set on the inner side of the first mounting groove 13 is fixedly connected to the inner end of the limiting post 14. Multiple first limiting grooves adapted to the limiting post 14 are formed on the outer circumferential surface of the guide tube 6, of which four first mounting grooves 13 are formed on the same horizontal plane, and the included angle between two adjacent first mounting grooves 13 is ninety degrees. At the same time, the inner circumferential surface of each placement port 7 is provided with two layers of the first mounting grooves 13, and the number of first limiting grooves formed on the outer circumferential surface of the guide tube 6 is the same as the number of limiting posts 14, and their positions correspond to each other to meet the assembly requirements.

[0029] Please see Figures 1 to 4A pressing guide post 16 is fixedly connected to the center of the upper surface of the base plate 8. A pressing guide barrel 12 is slidably connected to the top of the pressing guide post 16. A top plate 9 is fixedly connected to the bottom of the outer circumference of the pressing guide barrel 12. Multiple placement tubes 11 are fixedly connected to the top plate 9. A second limiting component is provided on the inner circumference of the pressing guide barrel 12. Therefore, when the operator presses the top plate 9 down, the top plate 9 will simultaneously drive all the placement tubes 11 on it to move down in the vertical direction. At the same time, with the help of the cooperation structure between the pressing guide post 16 and the pressing guide barrel 12, the movement trajectory of the top plate 9 can be precisely constrained to ensure that it can only move up and down and cannot rotate or deviate.

[0030] Please see Figures 1 to 6 The second limiting component includes multiple second mounting grooves 17 opened on the top of the inner circumferential surface of the pressing guide barrel 12. A limiting hemispherical head 19 that can be partially exposed is slidably connected in the second mounting groove 17. A second spring 18 with one end set on the inner side of the limiting hemispherical head 19 is fixedly connected to the inner side of the limiting hemispherical head 19. Multiple second limiting grooves adapted to the limiting hemispherical head 19 are opened at the top of the pressing guide post 16.

[0031] A third spring 20 is fixedly connected to the upper surface of the pressing guide post 16, and the end of the third spring 20 away from the pressing guide post 16 is fixedly connected to the top surface of the pressing guide barrel 12.

[0032] During the process of the operator pressing down on the top plate 9, the pressing guide barrel 12 will move down synchronously with the top plate 9 and slide along the axis of the pressing guide column 16. At the same time, the third spring 20 will be gradually compressed and accumulate elastic potential energy. As the pressing guide barrel 12 continues to move down, the pressing guide column 16 will exert a squeezing effect on the limiting hemispherical head 19, forcing the limiting hemispherical head 19 to compress the second spring 18 and retract into the second mounting groove 17.

[0033] When the pressing guide barrel 12 moves to a specific position, the limiting hemispherical head 19 will be engaged in the second limiting groove under the elastic force of the second spring 18, thereby locking the pressing guide barrel 12 in position. Since the elastic potential energy accumulated by the third spring 20 at this time is insufficient to push the limiting hemispherical head 19 out of the second limiting groove, the pressing guide barrel 12 will not automatically reset upward without the action of additional external force.

[0034] Only when the operator lifts the top plate 9 upwards will the pressing guide barrel 12 drive the relevant structure to make the limiting hemispherical head 19 slide out of the second limiting groove. At this time, the third spring 20 releases elastic potential energy, pushing the pressing guide barrel 12 to rise along the pressing guide column 16, and finally making the top plate 9 and the pressing guide barrel 12 return to the initial position together.

[0035] When the limiting hemispherical head 19 locks the pressing guide barrel 12 and keeps it stationary on the pressing guide post 16, the placement post 10 will simultaneously push the assembled lens upward until the lens is exposed from the top of the placement tube 11. This allows the operator to easily remove all the assembled lenses at once, greatly reducing the time spent on removing parts. In addition, the optical instrument lens assembly and positioning device is equipped with multiple guide tubes 6 of the same diameter. With the placement tubes 11 corresponding to the guide tubes 6, the operator can simultaneously and quickly place the lens from multiple guide tubes 6, effectively shortening the overall assembly cycle and significantly improving assembly efficiency.

[0036] The upper surface of the placement column 10 is provided with a tapered groove, which can better accommodate lens barrels of different sizes.

[0037] In summary, when using this optical instrument lens assembly and positioning device, the operator can first select a guide tube 6 with a suitable diameter according to the size of the lens barrel to be assembled, and insert it into the placement opening 7 of the placement plate 5. At this time, the upper and lower layers of limiting posts 14, evenly distributed at 90 degrees, in the placement opening 7 will be engaged into the first limiting groove on the outer circumference of the guide tube 6 under the elastic force of the first spring 15, thus achieving stable positioning of the guide tube 6. Subsequently, the lens is simultaneously placed into the corresponding placement tube 11 below through multiple guide tubes 6, and the lens barrel can be flexibly adapted and initially limited by the conical groove on the upper surface of the placement post 10.

[0038] After the lens is placed, the operator presses down on the top plate 9. The top plate 9 then moves all the placement tubes 11 synchronously downwards along the trajectory defined by the pressing guide post 16 and the pressing guide barrel 12 until the limiting hemispherical head 19 in the pressing guide barrel 12 engages with the second limiting groove of the pressing guide post 16. At this point, the placement tubes 11 and the placement post 10 cooperate to complete the lens assembly, and the placement post 10 pushes the assembled lens out from the top of the placement tube 11. The operator can then remove all finished products at once. When the next round of assembly is needed, lifting the top plate 9 releases the locking of the limiting hemispherical head 19, and the third spring 20 releases its elastic potential energy to reset the device. This achieves efficient and continuous lens assembly operations, which is especially suitable for mass production of lenses of various specifications.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
