Description

Technical Field

[0001] This application belongs to the field of laser processing technology, and more specifically, relates to a lens frame device and laser processing equipment. Background Technology

[0002] With the mature application of laser technology, the output power range of lasers has increased, leading to their widespread use in various processing fields. Generally, a laser cutting head requires the internal arrangement of optical lenses such as collimating lenses, focusing lenses, and protective lenses. The thickness of the collimating and focusing lenses varies depending on the power range of the laser cutting head. If the traditional "custom-made" lens mount structure is still used, it will result in a large number of parts and a significant increase in cost. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0040] Please see Figures 1 to 11 The eyeglass frame device provided in the embodiments of this application will now be described. The eyeglass frame device provided in the embodiments of this application includes a lens barrel 1 and a first elastic pressing assembly 2. The lens barrel 1 is provided with an inner cavity 11 for accommodating a lens 5. The first elastic pressing assembly 2 is disposed in the inner cavity 11 and is used to press the lens 5. It includes a first pressing member 21 and a first fixing member 22. The first fixing member 22 is connected to the lens barrel 1, and the first fixing member 22 is connected to the first pressing member 21. The side of the first pressing member 21 that contacts the lens 5 is provided with an arc-shaped smooth surface 211.

[0041] In this embodiment, the lens 5 can be an optical lens such as a collimating lens or a focusing lens.

[0042] The lens barrel 1 is cylindrical in shape and can be made of high-strength aluminum alloy, which has good mechanical properties and light weight. Its inner cavity 11 is a cylindrical through hole that can accommodate lenses 5 of different thicknesses.

[0043] The first fixing member 22 is a circular ring structure, and a connecting ring is provided on the outer wall of the lens barrel 1 along its circumference. The first fixing member 22 can be fixed to the connecting ring by bolts. The first fixing member 22 can also be connected to the lens barrel 1 by threaded connection.

[0044] The first clamping member 21 has a circular ring structure, and the arc-shaped smooth surface 211 is located on the side of the first clamping member 21 away from the first fixing member 22. The first clamping member 21 can be made of an elastic material.

[0045] During assembly, the lens 5 is first placed into the inner cavity 11 of the lens barrel 1, then the first clamping member 21 and the first fixing member 22 are placed in sequence, and finally the first fixing member 22 is connected to the lens barrel 1 by bolts.

[0046] The eyeglass frame device of this application embodiment is compatible with optical lenses of different thicknesses. The first elastic clamping component 2 undergoes controllable elastic deformation under the constraint of the first fixing member 22, which can clamp lenses 5 of different thicknesses inside the inner cavity 11 of the lens barrel 1. Furthermore, the side of the first clamping member 21 that contacts the lens 5 is a smooth arc-shaped surface 211, which can avoid the risk of scratching the lens 5 and extend the life of the lens 5.

[0047] The first elastic clamping assembly 2 also includes a first elastic element 23, which is disposed between the first clamping element 21 and the first fixing element 22.

[0048] The first elastic element 23 is disposed between the first clamping element 21 and the first fixing element 22 to provide elastic buffering and further optimize the uniformity and stability of the clamping force.

[0049] In this embodiment, the first elastic element 23 can be elastic silicone or a spring, preferably a wave-shaped spring ring. The wave-shaped spring ring has good elastic properties and can automatically adjust the clamping force when the lens 5 thermally expands, ensuring that the wave-shaped spring ring is always in a stable clamping state.

[0050] During the laser cutting process, the lens 5 is irradiated by a high-energy laser, causing a change in its size. Due to the elastic properties of the first elastic element 23, when the lens 5 changes size due to thermal expansion, the first elastic element 23 can automatically adjust the contact pressure between itself and the lens 5, ensuring that the lens 5 is always in a stable pressed state and preventing the lens 5 from loosening or shifting position.

[0051] The first clamping member 21 is provided with a first limiting groove 212 for accommodating the first elastic member 23 along the circumference of the first clamping member 21.

[0052] The first limiting groove 212 ensures that the first elastic element 23 can be accurately positioned during assembly and remain stable during operation, preventing it from shifting under the action of clamping force.

[0053] Please see Figures 9 to 11 The side wall of the first clamping member 21 is provided with several strip-shaped perforations 213.

[0054] When the first clamping member 21 is not made of an elastic material, multiple strip-shaped perforations 213 can be provided to allow the first clamping member 21 to generate elastic force under compression. The first fixing member 22 and the first clamping member 21 can be integrally formed.

[0055] The strip-shaped perforations 213 can be evenly distributed along the circumference of the first clamping member 21. When the first clamping member 21 is subjected to compressive force, its sidewalls can undergo local deformation at the strip-shaped perforations 213, thereby generating elastic restoring force and simulating the elastic properties of elastic materials.

[0056] Please see Figures 5 to 8 The frame assembly also includes a second elastic clamping component 3, which is disposed within the inner cavity 11, and the lens 5 is disposed between the first elastic clamping component 2 and the second elastic clamping component 3.

[0057] When the lens 5 is thin or is a collimating lens, a second elastic clamping component 3 can be placed in the inner cavity 11 of the lens barrel 1, followed by the lens 5 and the first elastic clamping component 2. When the lens 5 is thick or is a focusing lens, the second elastic clamping component 3 may not be used.

[0058] The second elastic clamping component 3 mainly provides additional elastic clamping force when the lens 5 is thin, ensuring that the lens 5 can be firmly fixed in the lens barrel 1 at different thicknesses.

[0059] The second elastic clamping component 3 may adopt the same structure as the first elastic clamping component 2.

[0060] The second elastic clamping assembly 3 includes a second clamping member 31 and a second elastic member 32. The second clamping member 31 abuts against the lens 5, and the second elastic member 32 is disposed on the side of the second clamping member 31 away from the lens 5.

[0061] The second clamping member 31 can adopt the same structure as the first clamping member 21, and the side of the second clamping member 31 near the lens 5 can also be provided with an arc-shaped smooth surface 211. The second elastic member 32 can adopt the same structure as the first elastic member 23.

[0062] When the first elastic clamping component 2 and the second elastic clamping component 3 are used simultaneously to clamp the lens 5, either the first elastic element 23 or the second elastic element 32 can be used.

[0063] The inner cavity 11 is provided with a limiting member 111 in the circumferential direction. The limiting member 111 is used to contact the lens 5 or the second elastic pressing assembly 3 to prevent the lens 5 or the second elastic pressing assembly 3 from falling out of the inner cavity 11.

[0064] In this embodiment, the limiting member 111 can be a plurality of limiting protrusions evenly distributed around the circumference of the inner cavity 11, or a limiting ring with an inner diameter smaller than the inner diameter of the inner cavity 11 can be provided. The design of the limiting member 111 ensures that the lens 5 or the second elastic clamping assembly 3 can be accurately positioned during assembly and remain stable during operation, preventing it from falling out of the inner cavity 11 due to vibration or impact.

[0065] When the lens 5 is relatively thick and the second elastic clamping component 3 is not used, the limiting member 111 can directly contact the lens 5, and the side of the limiting member 111 that contacts the lens 5 can be set as a curved smooth surface 211. When the lens 5 is relatively thin and the second elastic clamping component 3 is required, the limiting member 111 contacts the second elastic clamping component 3.

[0066] The limiting member 111 is provided with a second limiting groove 1111 for accommodating the second elastic member 32 along the length direction of the limiting member 111.

[0067] The second limiting groove 1111 ensures that the second elastic element 32 can be accurately positioned during assembly and remain stable during operation, preventing it from shifting under the action of clamping force.

[0068] When the lens 5 is relatively thick and the second elastic clamping component 3 is not used, the limiting member 111 can directly contact the lens 5, and the limiting member 111 does not need to be provided with the second limiting groove 1111.

[0069] The lens barrel 1 is also provided with a connector 4 for connecting to an external cutting head.

[0070] Connector 4 is located on the outside of the lens barrel 1 and is used to connect the lens frame assembly to the external cutting head. In this embodiment, when the lens 5 is a collimating lens, connector 4 can specifically be a locking ring sleeved on the outside of the lens barrel 1, with the locking ring close to the limiting member 111, and the lens barrel 1 is locked to the focusing shaft of the external cutting head by the locking ring. When the lens 5 is a focusing lens, connector 4 can specifically be a bolt, which passes through the connecting ring on the outside of the lens barrel 1 and is connected to the coaxial lens cavity of the external cutting head.
