Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, specifically to an optical lens with adjustment function. 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, and long focal length); by field of view (wide-angle, standard, and telephoto); and by structure (fixed aperture fixed focal length lenses, manual aperture fixed focal length lenses, automatic aperture fixed focal length lenses, manual zoom lenses, automatic zoom lenses, automatic aperture motorized zoom lenses, and motorized triple-variable (aperture, focal length, and focus are all variable) lenses). Industrial optical lenses are widely used for locating and detecting objects with extremely high reflectivity, such as metals, glass, film, and wafers.

[0003] A search revealed a patent publication number CN218122328U published on December 23, 2022, describing an optical lens with an adjustment function. The general description includes a base and an optical lens body mounted on the base. The outer wall of the optical lens body is provided with several sets of protective shells via buffer components. A protective lens and a focusing lens are mounted on the side of the optical lens body away from the base, with the focusing lens located closer to the base. Control units are rotatably connected to both sides of the optical lens body via rotating shafts. A rotating gear is located at the end of the rotating shaft away from the control unit. Adjustment devices are correspondingly arranged inside the optical lens body, meshing with the rotating gear. These adjustment devices are slidably connected to a zoom lens and a compensation lens via clamping blocks. Clamping blocks are installed at the upper and lower ends of the zoom lens and the compensation lens. The two sets of adjustment devices are located at opposite ends of the zoom lens and the compensation lens.

[0004] Although the existing technical solution described above can adjust the position of the zoom lens or the compensation lens to meet the requirements of different measurement conditions, the zoom lens and the compensation lens of the device are only connected and fixed by two clamping blocks distributed at both ends, which makes the zoom lens and the compensation lens prone to deflection, resulting in measurement errors and reducing the stability of the equipment. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an optical lens with adjustment capabilities, thereby resolving the problem mentioned in the background technology that zoom lenses and compensation lenses are prone to skew, leading to measurement errors and reducing the stability of the equipment.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an optical lens with an adjustment function, comprising a mounting cylinder, including a first adjustment cylinder, one end of which has an observation port, the interior of which is provided with a focusing lens, the inner wall of which has four evenly distributed limiting grooves, the first adjustment cylinder being located inside the mounting cylinder, the outer wall of which is fixedly connected with four limiting sliders that are slidably connected to the limiting grooves, the top end of which is fixedly connected with a first fixing block, the first fixing block having a first threaded hole, and the bottom end of which has a sliding through groove. A second adjusting cylinder is slidably connected inside an adjusting cylinder. A second fixing block is fixedly connected to the bottom end of the second adjusting cylinder through a sliding groove. A second threaded hole is provided on the second fixing block. A second threaded rod and a first threaded rod are threadedly connected inside the second threaded hole and the first threaded hole, respectively. Both ends of the first threaded rod and the second threaded rod are rotatably connected to the inner side wall of the mounting cylinder. One end of the first threaded rod and the second threaded rod are connected to a first knob and a second knob through the mounting cylinder. A zoom lens is provided on the inner side wall of the first adjusting cylinder near the observation port. A compensation lens is provided on the inner side wall of the second adjusting cylinder near the zoom lens.

[0009] By adopting the above technical solution, when using the equipment, rotating the first knob and the second knob drives the first threaded rod and the second threaded rod to rotate. The first threaded rod and the second threaded rod respectively drive the first fixed block and the second fixed block to move. The first fixed block and the second fixed block drive the first adjusting cylinder and the second adjusting cylinder to move, thereby driving the zoom lens and the compensation lens to move, so as to adjust the position of the zoom lens and the compensation lens, so that the equipment meets the requirements of different measurement conditions. The limiting groove and the limiting slider cooperate to limit the first adjusting cylinder to prevent the first adjusting cylinder and the zoom lens from shaking or shifting. The first adjusting cylinder is used to limit the second adjusting cylinder to prevent the second adjusting cylinder and the compensation lens from shaking or shifting, thereby achieving the purpose of avoiding measurement errors and improving the stability of the equipment.

[0010] Optionally, a protective lens is provided inside the observation port near the outer wall of the mounting cylinder.

[0011] By adopting the above technical solution, the protective lens is used to protect the focusing lens, preventing it from being broken by impact, thereby improving the stability of the equipment.

[0012] Optionally, a scratch-resistant collar that mates with the observation port is fixedly connected to the outer wall of the mounting cylinder.

[0013] By adopting the above technical solution, the anti-scratch ring is used to protect the observation port, reducing the probability of the protective lens being scratched and thus improving the stability of the equipment.

[0014] Optionally, a protective sleeve is fitted on the outer wall of the mounting cylinder, and shock-absorbing sponge is provided between the protective sleeve and the mounting cylinder.

[0015] By adopting the above technical solution, the protective cylinder and the shock-absorbing sponge are used to protect the equipment, thereby reducing the vibration damage to the cylinder when the equipment is bumped, thus improving the stability of the equipment.

[0016] Optionally, sealing gaskets are provided at both ends of the protective cylinder and the mounting cylinder.

[0017] By adopting the above technical solution, the sealing gasket is used to improve the sealing between the protective cylinder and the mounting cylinder, preventing water and dust from entering the interior of the protective cylinder and causing pollution and damage to the shock-absorbing sponge, thereby achieving the purpose of improving equipment stability.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] This adjustable optical lens, when used with the equipment, rotates the first and second knobs, causing the first and second threaded rods to rotate. These rods, in turn, move the first and second fixed blocks, which in turn move the first and second adjusting cylinders. This, in turn, moves the zoom lens and the compensation lens, adjusting their positions to meet different measurement requirements. A limiting groove and a limiting slider cooperate to limit the movement of the first adjusting cylinder, preventing it and the zoom lens from shaking or shifting. The first adjusting cylinder also limits the movement of the second adjusting cylinder, preventing it and the compensation lens from shaking or shifting. This effectively avoids measurement errors and improves equipment stability. Attached Figure Description

The first adjustment cylinder 2 is located inside the mounting cylinder 1. Four limiting sliders 5, which are slidably connected to the limiting grooves 4, are fixedly connected to the outer wall of the first adjustment cylinder 2. A first fixing block 6 is fixedly connected to the top of the first adjustment cylinder 2, and a first threaded hole is provided on the first fixing block 6. A sliding through groove 7 is provided at the bottom of the first adjustment cylinder 2. A second adjustment cylinder 8 is slidably connected inside the first adjustment cylinder 2. A second fixing block 9, penetrating the sliding through groove 7, is fixedly connected to the bottom of the second adjustment cylinder 8. A second threaded hole is provided on the second fixing block 9. A second threaded rod 10 and a first threaded rod 11 are threadedly connected to the interior of the second threaded hole and the first threaded hole, respectively. Both ends of the first threaded rod 11 and the second threaded rod 10 are rotatably connected to the inner wall of the mounting cylinder 1. One end of each threaded rod 11 and the second threaded rod 10 penetrates the mounting cylinder 1 and is connected to the first threaded rod 11. Knob 12 and second knob 13 are used. A zoom lens 14 is located on the inner wall of the first adjusting cylinder 2 near the observation port, and a compensating lens 15 is located on the inner wall of the second adjusting cylinder 8 near the zoom lens 14. When using the equipment, rotating the first knob 12 and second knob 13 drives the first threaded rod 11 and the second threaded rod 10 to rotate. The first threaded rod 11 and the second threaded rod 10 respectively drive the first fixed block 6 and the second fixed block 9 to move. The first fixed block 6 and the second fixed block 9 drive the first adjusting cylinder 2 and the second adjusting cylinder 8 to move, thereby driving the zoom lens 14 and the compensating lens 15 to move, so as to adjust the position of the zoom lens 14 and the compensating lens 15 to meet the requirements of different measurement conditions. The limiting groove 4 cooperates with the limiting slider 5 to limit the first adjusting cylinder 2 to prevent the first adjusting cylinder 2 and the zoom lens from shaking and shifting. The first adjusting cylinder 2 is used to limit the second adjusting cylinder 8 to prevent the second adjusting cylinder 8 and the compensating lens 15 from shaking and shifting, thereby avoiding measurement errors and improving the stability of the equipment.

[0029] Reference Figure 1 and Figure 2 A protective lens 16 is provided inside the observation port near the outer wall of the mounting cylinder 1. The protective lens 16 is used to protect the focusing lens 3 and prevent the focusing lens 3 from being broken by impact, thereby improving the stability of the equipment.

[0030] Reference Figure 1 and Figure 2 A scratch-resistant collar 17 is fixedly connected to the outer wall of the mounting cylinder 1 to cooperate with the observation port. The scratch-resistant collar 17 is used to protect the observation port and reduce the probability of the protective lens 16 being scratched, thereby improving the stability of the equipment.

[0031] Reference Figures 1-4 A protective sleeve 18 is fitted on the outer wall of the mounting cylinder 1. A shock-absorbing sponge 19 is provided between the protective sleeve 18 and the mounting cylinder 1. The protective sleeve 18 and the shock-absorbing sponge 19 work together to protect the equipment, thereby reducing the vibration damage to the mounting cylinder 1 when the equipment is bumped, thus improving the stability of the equipment.

[0032] Reference Figure 3 and Figure 4 Sealing gaskets 20 are provided near both ends of the protective cylinder 18 and the mounting cylinder 1.

[0033] In summary, the working principle and process of this adjustable optical lens are as follows: During use, rotating the first knob 12 and the second knob 13 drives the first threaded rod 11 and the second threaded rod 10 to rotate. The first threaded rod 11 and the second threaded rod 10 respectively move the first fixed block 6 and the second fixed block 9. The first fixed block 6 and the second fixed block 9 then move the first adjusting cylinder 2 and the second adjusting cylinder 8, thereby moving the zoom lens 14 and the compensation lens 15 to adjust their positions, allowing the device to meet the requirements of different measurement conditions. The limiting groove 4 cooperates with the limiting slider 5 to limit the first adjusting cylinder 2, preventing it and the zoom lens from shaking or shifting. The first adjusting cylinder 2 also limits the second adjusting cylinder 8, preventing it from shifting. The joint cylinder 8 and the compensating lens 15 shake and shift to avoid measurement errors and improve equipment stability. The protective lens 16 protects the focusing lens 3 from impacts and prevents it from breaking, thus improving equipment stability. The anti-scratch ring 17 protects the observation port and reduces the probability of scratches on the protective lens 16, thus improving equipment stability. The protective cylinder 18 works in conjunction with the shock-absorbing sponge 19 to protect the equipment and reduce vibration damage to the mounting cylinder 1 when the equipment is impacted, thus improving equipment stability. The sealing gasket 20 improves the seal between the protective cylinder 18 and the mounting cylinder 1, preventing water and dust from entering the interior of the protective cylinder 18 and contaminating or damaging the shock-absorbing sponge 19, thus improving equipment stability.
