DETAILED DESCRIPTION

[0030] The terms "comprise", "include", "contain" or "characterized by" in the specification and claims of the present application and the drawings are synonymous with "consist of" or "consisting of" and are open-ended, and do not exclude additional, unrecited elements or method steps. "Comprise" is a term of art used in the claim language, which means that the recited elements are present, but that other elements can also be added.

[0031] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings, in addition, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0032] With the rapid development of laser technology, laser heads as the core components of laser processing equipment have greatly expanded their performance and application fields. Laser heads not only play an important role in traditional industrial processing fields such as cutting, welding, marking, etc., but also show great potential in high-precision fields such as medical treatment, communication, scientific research, etc.

[0033] In the installation process of laser head lenses, the threaded connection method is currently widely used to fix the lenses in the lens barrel. Although this method is simple and easy to implement, the friction between the threads during tightening can generate metal debris, which can easily drift and adhere to the lens surface, affecting the efficiency and quality of laser transmission, and even causing laser beam scattering or energy loss, reducing processing precision and product quality. In addition, debris can scratch or corrode the lens, reducing its service life and increasing maintenance costs.

[0034] Therefore, the present application proposes a lens seat assembly and a laser head, which can effectively improve the problem of debris falling during lens installation and reduce the risk of lens dust falling.

[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0036] In this document, referring to "embodiments" means that the specific features, structures or characteristics described in combination with the embodiments can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily mean the same embodiment, nor is it an independent or alternative embodiment to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0037] Referring to Figure 1 The embodiments of the present application provide a lens seat assembly, comprising:

[0038] The lens seat 1 has a mounting cavity 101, and along the axial direction of the lens seat 1, the lens 2, the first retainer ring 3 and the second retainer ring 4 are sequentially arranged in the mounting cavity 101;

[0039] The first retainer ring 3 is located between the lens 2 and the second retainer ring 4, one side of the first retainer ring 3 abuts against the lens 2, and the other side abuts against the second retainer ring 4;

[0040] One of the mirror seat 1 and the second retaining ring 4 is provided with a clamping groove 5, and the other is provided with a clamping protrusion 6. When the second retaining ring 4 is installed in place in the mirror seat 1, the mirror seat 1 or the second retaining ring 4 is rotated to make the clamping protrusion 6 clamped into the clamping groove 5.

[0041] During the installation process of the mirror seat assembly of the present application, referring to Figure 2 , the lens 2 is first installed at the bottom of the installation cavity 101, and then the first retaining ring 3 is installed in the installation cavity 101, with one side tightly abutting the lens 2. Then, the second retaining ring 4 is installed in the installation cavity 101, tightly abutting the other side of the first retaining ring 3. Since the mirror seat 1 and the second retaining ring 4 are respectively provided with a clamping groove 5 and a clamping protrusion 6, when the second retaining ring 4 is installed in place, the mirror seat 1 or the second retaining ring 4 is rotated to make the clamping protrusion 6 clamped into the clamping groove 5, realizing the mutual clamping between the mirror seat 1 and the second retaining ring 4. This clamping structure will not produce debris due to friction to pollute the lens. At the same time, since the first retaining ring 3 is an elastic member, it can provide an elastic force for the second retaining ring 4, so that the clamping structure is more stable under the action of the elastic force, effectively avoiding the problem of loose installation caused by displacement change.

[0042] Referring to Figure 3 , the clamping groove 5 includes an opening part 501, a guide part 502 and a clamping part 503;

[0043] The opening part 501 extends along the axial direction of the mirror seat 1. The guide part 502 is located between the opening part 501 and the clamping part 503. One end of the guide part 502 is in vertical communication with the opening part 501, and the other end of the guide part 502 is in vertical communication with the clamping part 503. The clamping part 503 is provided with a limiting protrusion on the side close to the opening part 501, for limiting the circumferential movement of the clamping protrusion 6.

[0044] It can be seen that the guide part 502 extends along the circumference of the mirror seat 1. When the mirror seat 1 or the second retaining ring 4 is subjected to a rotating force, the clamping protrusion 6 is easy to slide circumferentially in the guide part 502, causing the clamping to be loose. Therefore, through the design of the limiting protrusion of the clamping part 503, the circumferential movement of the clamping protrusion 6 can be effectively limited, and it is axially limited under the elastic action of the first retaining ring 3, thereby enhancing the stability of the clamping.

[0045] To further improve the reliability of the clamping, the cross-sectional size of the opening part 501 is designed to be not greater than the cross-sectional size of the clamping part 503. When the clamping protrusion 6 is inserted into the clamping groove 5, the clamping protrusion 6 is elastically deformed, and after the insertion action is completed, the clamping protrusion 6 quickly returns to the initial state, thereby achieving the effect of tight connection. This not only enhances the mechanical stability of the clamping structure, but also effectively resists the action of external forces (such as vibration or rotating force), prevents the clamping from being loose, and ensures the long-term reliability of the connection.

[0046] In some embodiments, referring to Figure 1 and Figure 4 , the clamping groove 5 is arranged at the mounting end of the mirror seat 1, the outer wall of the second retaining ring 4 is provided with a clamping protrusion 6, the clamping protrusion 6 is clamped and matched with the clamping groove 5, and the cross-sectional size of the clamping protrusion 6 is not less than the cross-sectional size of the clamping part 503.

[0047] It should be noted that the clamping protrusion 6 is integrally formed with the second retaining ring 4, and the shape can be cylindrical, cuboid, etc.

[0048] In other embodiments, referring to Figure 5 , the clamping groove 5 is arranged at the clamping end of the second retaining ring 4, the mirror seat 1 is correspondingly provided with a mounting hole 601, the mounting hole 601 corresponds to the clamping groove 5, the clamping protrusion 6 is inserted into the clamping groove 5 through the mounting hole 601, and the clamping protrusion 6 is clamped with the clamping groove 5.

[0049] In this embodiment, since the clamping protrusion 6 protrudes on the inner wall of the mounting cavity 101 of the mirror seat 1, in order to install smoothly, the lens 2 and the first retaining ring 3 need to be installed in place first, then the clamping protrusion 6 is inserted into the mounting hole 601, and finally the second retaining ring 4 is installed into the mounting cavity 101, and the clamping protrusion 6 and the clamping groove 5 are clamped by rotating the mirror seat 1 or the second retaining ring 4.

[0050] In order to avoid metal debris generated between the clamping protrusion 6 and the mounting hole 601 during fixing, a gluing method can be used between the mounting hole 601 and the clamping protrusion 6. Of course, other suitable installation methods can also be selected according to actual conditions, and the present application does not make specific limitations in this regard.

[0051] In some embodiments, referring to Figure 6 , a first shrinkage groove 301 and a second shrinkage groove 302 are arranged at intervals along the axial direction of the first retaining ring 3, and the first shrinkage groove 301 and the second shrinkage groove 302 are arranged in a staggered manner.

[0052] It should be noted that the shrinkage grooves are arranged on the first retaining ring 3, and the absorption effect of the slot structure on the elastic deformation is used to improve the elastic performance of the first retaining ring 3. At the same time, the first shrinkage groove 301 and the second shrinkage groove 302 are designed in a staggered manner, which not only ensures the overall structural stability of the first retaining ring 3, but also further optimizes the elastic deformation capacity, thereby enhancing the functional performance of the first retaining ring 3 in the mirror seat assembly.

[0053] To further increase the elasticity of the first stop ring 3, the first and second shrinkage grooves 301 and 302 each include a first sub-shrinkage groove 311 and a second sub-shrinkage groove 312, which are oppositely distributed along the circumference of the first stop ring 3.

[0054] It should be noted that the design of the oppositely distributed grooves can make the stress more evenly distributed, significantly enhancing the elastic response capability of the first stop ring 3 when stressed. If the elasticity of the first stop ring 3 has higher requirements in actual application, the number of the first and second sub-shrinkage grooves 311 and 312 can be flexibly increased according to the specific working conditions and performance indicators.

[0055] In some embodiments, referring to Figure 1 and Figure 5 , the second stop ring 4 is provided with a mounting groove 7 on the inner wall of one end thereof away from the lens 2, and the mounting groove 7 is arranged along the axial direction of the second stop ring 4.

[0056] When the second stop ring 4 is completely installed in the mounting cavity 101 of the lens holder 1 and cannot provide a stress point, the second stop ring 4 can be rotated by using a mounting tool through the mounting groove 7 to complete the clamping action between the second stop ring 4 and the lens holder 1.

[0057] The mounting groove 7 is arranged on the inner wall of one end of the second stop ring 4, which can ensure that the second stop ring 4 is subjected to a uniformly distributed rotating force.

[0058] In some embodiments, the first stop ring 3 is made of an elastic material, such as phosphor bronze, as an elastic element, which can exert an elastic force on the second stop ring 4, thereby avoiding the problem of loose installation due to displacement change of the clamping structure. The material of the first stop ring 3 can also be other materials with good elasticity, corrosion resistance, wear resistance, and high strength, such as beryllium copper, tin bronze, etc.

[0059] The application also provides a laser head comprising the lens holder assembly as described above.

[0060] The embodiments of the application are described in detail above, and the principles and implementation modes of the application are described by applying specific examples. The above description of the embodiments is only used to help understand the method of the application and its core idea; at the same time, for those skilled in the art, according to the idea of the application, the specific implementation mode and application range will be changed; in view of the above, the content of the specification should not be understood as a limitation of the application.
