Description
A lens clamping spring and optical device Technical Field
[0001] This utility model relates to the field of precision optical technology, and more specifically, to a lens clamping spring and optical device. Background Technology
[0002] In optical systems, lens clamping and fixation are crucial for ensuring stable optical performance. Traditional lens clamping springs are mostly circular springs, which are simple in design and easy to manufacture, and are widely used in various optical devices.
[0003] However, this type of circular spring has some inherent drawbacks during clamping. Because the contact points between the spring and the lens surface cannot be precisely aligned, the contact points are randomly distributed, resulting in uneven stress distribution on the lens surface. During clamping, relative slippage can easily occur between the lens and the spring, causing the lens to fail to be clamped centered, which in turn alters the optical path and affects the overall performance of the optical system. Summary of the Invention
[0004] The purpose of this invention is to provide a lens clamping spring and an optical device that can fix and clamp a lens, prevent relative slippage of the lens, maintain high coaxiality, and achieve stress uniformity.
[0005] The embodiments of this utility model can be implemented as follows:
[0006] In a first aspect, this utility model provides a lens clamping spring, comprising:
[0007] A reed body has an optical hole and multiple baffles. The multiple baffles are arranged around the axis of the optical hole and are equidistant from the axis of the optical hole. The baffles protrude from the surface of the reed body and are used to hold the lens.
[0008] In an optional embodiment, the baffle includes a connecting part, an abutting part, and a clamping part connected in sequence. One end of the connecting part is connected to the spring body. The abutting part protrudes toward the axis of the light hole and is used to abut against the mirror surface of the lens. The clamping part is used to clamp the side of the lens.
[0009] In an optional embodiment, the abutting portion includes a first bending member and a second bending member connected in sequence. One end of the first bending member is connected to the end of the connecting portion away from the spring body. One end of the second bending member is connected to the first bending member. The other end of the second bending member is connected to the clamping portion. The connecting portion and the clamping portion are located on the same plane. Both the first bending member and the second bending member are bent toward the axis of the light hole.
[0010] In an optional embodiment, the included angle between the first bending member and the second bending member is an acute angle.
[0011] In an optional embodiment, the abutting portion includes an arc-shaped bent plate, the two ends of which are connected to the connecting portion and the clamping portion respectively, and the bent plate is bent toward the axis of the light hole.
[0012] In an optional embodiment, a plurality of the baffles are arranged in a circumferential array around the axis of the light aperture.
[0013] In an optional embodiment, the baffle is an elastic baffle, and the distance between the baffle and the axis of the light aperture is less than the radius of the lens.
[0014] In an optional embodiment, the reed body is further provided with a plurality of arc-shaped grooves at intervals, the center of the grooves coincides with the axis of the light hole, and the baffle is disposed on the side wall of the groove near the end of the light hole.
[0015] In an optional embodiment, the reed body is further provided with a plurality of mounting holes, which are arranged around the axis of the optical aperture.
[0016] Secondly, the present invention provides an optical device including a lens clamping spring as described in any of the foregoing embodiments.
[0017] The beneficial effects of the lens clamping spring and optical device provided in this embodiment of the invention include:
[0018] This invention relates to a lens clamping spring, comprising a spring body with an aperture and multiple baffles arranged around the axis of the aperture, all equidistant from it. The baffles protrude from the surface of the spring body and are used to clamp the lens. By arranging multiple vertical baffles around the aperture, this invention clamps the lens, ensuring that the lens and aperture remain coaxial. This high coaxiality between the spring and the lens prevents the lens from shifting relative to the spring, ensuring the spring always presses the lens centered and achieves stress uniformity during clamping. This invention effectively clamps the lens securely, preventing relative slippage, maintaining high coaxiality, and achieving stress uniformity. Attached Figure Description

[0030] First Embodiment
[0031] Referring to Figures 1 and 2, the lens clamping spring 100 provided by this utility model includes a spring body 10, on which a light hole 11 is formed. Multiple baffles 12 are disposed on the spring body 10, surrounding the axis of the light hole 11 and equidistant from it. The baffles 12 protrude from the surface of the spring body 10 and are used to clamp the lens 200. It can be understood that the lens clamping spring 100 of this embodiment, by arranging multiple vertical baffles 12 around the light hole 11, clamps the lens 200, ensuring that the lens 200 and the light hole 11 remain coaxial. This achieves high coaxiality between the spring and the lens 200, ensuring that the position of the lens 200 does not shift relative to the spring, and that the spring always presses the lens 200 centered, thus achieving stress uniformity during the clamping process.
[0032] Referring to Figure 3, specifically, the baffle 12 includes a connecting portion 121, an abutting portion 122, and a clamping portion 123 connected in sequence. One end of the connecting portion 121 is connected to the spring body 10. The abutting portion 122 protrudes towards the axis of the light aperture 11. The abutting portion 122 abuts against the mirror surface 201 of the lens 200. The clamping portion 123 clamps the side surface 202 of the lens 200. It can be understood that in this embodiment, the baffle 12 stands upright on the spring body 10, wherein the abutting portion 122 protrudes relative to the connecting portion 121 and the clamping portion 123 towards the axis of the light aperture 11, thereby enabling the abutting portion 122 to support the mirror surface 201 of the lens 200, and thus allowing the baffle 12 to support the lens 200 above the spring body 10. The lens 200 is spaced apart from the reed body 10 to prevent line contact between the lens 200 and the reed body 10, avoid friction that could generate debris and contaminate the surface of the lens 200, and protect the lens 200. During the clamping process, the clamping part 123 is in close contact with the side 202 of the lens 200, and the clamping part 123 applies radial pressure to the lens 200, thereby clamping and fixing the lens 200, and making the lens 200 coaxial with the aperture 11, preventing the lens 200 from shifting.
[0033] Further, in this embodiment, the abutment portion 122 includes a first bent member 1221 and a second bent member 1222 connected in sequence. One end of the first bent member 1221 is connected to the end of the connecting portion 121 away from the spring body 10. One end of the second bent member 1222 is connected to the first bent member 1221, and the other end of the second bent member 1222 is connected to the clamping portion 123. The connecting portion 121 and the clamping portion 123 are located on the same plane, and both the first bent member 1221 and the second bent member 1222 are bent towards the axis of the light hole 11. It can be understood that in this embodiment, the abutment portion 122 has a "V" shaped structure. Specifically, in this embodiment, the connecting portion 121 and the clamping portion 123 are upright relative to the spring body 10. The first bending member 1221 and the second bending member 1222 protrude relative to the connecting portion 121 and the clamping portion 123 toward the axis of the light hole 11, so that the second bending member 1222 can support the mirror surface 201 of the lens 200, thereby allowing the baffle 12 to support the lens 200 above the spring body 10. The lens 200 is spaced apart from the spring body 10 to prevent the lens 200 from making line contact with the spring body 10, avoid friction to generate debris, contaminate the surface of the lens 200, and protect the lens 200.
[0034] Specifically, in this embodiment, the included angle between the first bending member 1221 and the second bending member 1222 is an acute angle. It is understood that since the lens 200 in this embodiment is a convex lens, the mirror surface 201 of the lens 200 is convex. By setting the included angle between the first bending member 1221 and the second bending member 1222 to an acute angle, the included angle between the first bending member 1221 and the clamping part 123 becomes an obtuse angle. When the clamping part 123 is in contact with the side surface 202 of the lens 200, the contact area between the first bending member 1221 and the mirror surface 201 of the lens 200 can be increased, further improving the stability of the baffle 12 in clamping the lens 200.
[0035] Of course, in other embodiments, the lens 200 may also be a concave lens, and the present invention does not limit the type of lens 200.
[0036] In another embodiment of this utility model, the abutment portion 122 includes an arc-shaped bent plate. The two ends of the bent plate are connected to the connecting portion 121 and the clamping portion 123, respectively. The bent plate is bent towards the axis of the light aperture 11. It is understood that the abutment portion 122 can also have a "C"-shaped structure. It is understood that the connecting portion 121 and the clamping portion 123 are upright relative to the spring body 10, and the bent plate protrudes relative to the axis of the connecting portion 121 and the clamping portion 123 towards the light aperture 11, thereby enabling the upper half of the bent plate to support the mirror surface 201 of the lens 200, and thus allowing the baffle 12 to support the lens 200 above the spring body 10. The lens 200 is spaced apart from the spring body 10 to prevent line contact between the lens 200 and the spring body 10, avoid friction that generates debris, contaminates the surface of the lens 200, and protects the lens 200.
[0037] Please continue referring to Figure 1. In this embodiment, a plurality of baffles 12 are arranged in a circumferential array around the axis of the light aperture 11. It can be understood that in this embodiment, the distance between the plurality of baffles 12 is equal, thereby making the force applied by the baffles 12 to the lens 200 more uniform and preventing the lens 200 from slipping relative to the reed body 10.
[0038] Specifically, in this embodiment, the number of baffles 12 is set to three. The included angle between the three baffles 12 and the axis of the light aperture 11 is 120°.
[0039] Of course, in other embodiments, the number of baffles 12 can be set to two, and the angle between the two baffles 12 and the axis of the light aperture 11 is 180°. Optionally, the number of baffles 12 can also be set to other numbers, such as four or more, and the angle between the baffles 12 and the axis of the light aperture 11 can be adjusted adaptively. As long as the baffles 12 can clamp the lens 200, the present invention does not limit the number of baffles 12.
[0040] Furthermore, the baffle 12 is an elastic baffle 12. The distance between the baffle 12 and the axis of the aperture 11 is less than the radius of the lens 200. It is understood that when the lens 200 is installed, the lens 200 spreads out the multiple baffles 12, and the baffles 12, under elastic action, apply radial pressure to the lens 200, thereby clamping and fixing the lens 200. By setting the baffle 12 as an elastic baffle 12, it is also easier to install or remove the lens 200.
[0041] Furthermore, the reed body 10 is also provided with a plurality of arc-shaped grooves 13 at intervals. The center of the groove 13 coincides with the axis of the light aperture 11. A baffle 12 is disposed on the side wall of the groove 13 near the light aperture 11. It can be understood that, in this embodiment, by providing the groove 13, the baffle 12 can move elastically relative to the reed body 10, avoiding hard contact during lens 200 installation that could cause damage to the lens 200.
[0042] In this embodiment, the reed body 10 is also provided with a plurality of mounting holes 14. The mounting holes 14 are arranged around the axis of the optical aperture 11. It can be understood that the mounting holes 14 are used to fix the reed body 10.
[0043] Second Embodiment
[0044] This embodiment provides an optical device, which includes the lens clamping spring 100 described in the first embodiment above. Specifically, the optical device can be an optical experimental device, a photolithography device, a semiconductor laser device, etc., and this utility model does not limit the specific type of optical device.
[0045] The beneficial effects of the lens clamping spring 100 and optical device provided in this embodiment of the invention include:
[0046] The lens clamping spring 100 of this invention includes a spring body 10, on which a light hole 11 is formed. Multiple baffles 12 are disposed on the spring body 10, arranged around the axis of the light hole 11 and equidistant from it. The baffles 12 protrude from the surface of the spring body 10 and are used to clamp the lens 200. This invention, by arranging multiple vertical baffles 12 around the light hole 11 and clamping the lens 200, ensures that the lens 200 and the light hole 11 remain coaxial, achieving high coaxiality between the spring and the lens 200. This prevents the lens 200 from shifting relative to the spring, ensuring that the spring always presses the lens 200 centered, thus achieving stress uniformity during clamping. This invention can achieve fixed clamping of the lens 200, preventing relative slippage, maintaining high coaxiality, and achieving stress uniformity.
