[0020] It should also be noted that, unless otherwise explicitly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Please refer to Figure 1 , Figure 4 As shown, this application embodiment provides a frame module 10, including: a module body 11, on which a detachable frame 12 is disposed, the frame 12 being used to hold lenses; the module body 11 is also provided with a heat dissipation structure to form a recirculating high-pressure gas for heat dissipation within the module body 11; the module body 11 is connected between an optical module 20 and a laser processing module 30, so that the light beam emitted from the optical module 20 passes through the lenses on the frame 12 and is directed towards the laser processing module 30.

[0022] like Figure 4 As shown, the main body 11 of the module is located between the optical module 20 and the laser processing module 30, serving as a bridge connecting the optical module 20 and the laser processing module 30; the optical module 20 emits a light beam, which passes through the lens of the frame 12 and is then directed towards the laser processing module 30, which uses the light beam from the optical module 20 and the lens to perform laser processing.

[0023] The frame 12 is detachably connected to the module body 11. Each frame 12 is configured with one lens. By replacing different frames 12, the module body 11 can be adapted to different lens specifications, thereby making the module body 11 compatible with multiple lens specifications.

[0024] Generally, a DOE diffraction lens can be installed on the frame 12. The light beam from the optical module 20 is diffracted after passing through the DOE diffraction lens to form a diffracted beam, which is then directed towards the laser processing module 30. The light beam is diffracted and transmitted through the DOE diffraction lens, and the DOE diffraction lens achieves optical field modulation through its surface microstructure. Depending on the optical path, different DOE diffraction lenses are required, and different DOE diffraction lenses are installed on different frames 12. The frame 12 and the module body 11 are detachable for quick replacement, allowing the module body 11 to accommodate lenses of various conventional sizes such as 0.5 inches, 1 inch, and 2 inches.

[0025] In addition, a heat dissipation structure is provided on the main body 11 of the module. The heat dissipation structure dissipates heat to the lens by forming a backflow of high-pressure gas in the main body 11, so that the lens is heated evenly and avoids the film damage and medium deterioration caused by local heat accumulation in the lens. It can maintain the optical performance stability of the lens, extend its life and improve the system energy efficiency, so that the equipment can operate at high power.

[0026] Furthermore, the laser processing module 30 also generates high heat during laser processing, and the heat dissipation structure also dissipates heat from the laser processing module 30 to reduce aging of the laser processing module 30 and ensure the stability of processing quality.

[0027] Therefore, the lens frame module 10 provided in this application embodiment is detachably connected to the module body 11 via the lens frame 12 to accommodate lenses of different specifications and meet various optical path scenarios for lenses. At the same time, a heat dissipation structure is provided in the module body 11. The heat dissipation structure dissipates heat from the lenses by forming a reflux high-pressure gas in the module body 11, and can also dissipate heat from the laser processing module 30. Efficient heat dissipation provides a strong guarantee for the stable high-power operation of the equipment, and stable temperature ensures the continuous stability of laser output power, thereby improving processing efficiency and processing quality.

[0028] Specifically, the module body 11 has openings at both ends and is hollow inside to form an optical channel 110 within the module body 11. The two ends of the module body 11 are respectively connected to the optical module 20 and the laser processing module 30. The central axis s of the optical channel 110, the optical axis of the optical module 20, and the axis of the laser processing module 30 are collinear. The frame 12 is detachably connected to the optical channel 110 of the module body 11.

[0029] The main body 11 of the module has openings at both ends to connect with the optical module 20 and the laser processing module 30 respectively. In this way, the light beam emitted from the optical module 20 enters the optical channel 110 of the main body 11 of the module, and then passes through the lens on the frame 12 in the optical channel 110 to form the final emitted light that is directed to the laser processing module 30 for laser processing.

[0030] The central axis s of the optical channel 110 is collinear with the optical axis of the optical module 20 and the axis of the laser processing module 30. When the three are collinear, the consistency and accuracy of the installation can be guaranteed, and the beam can be propagated in a straight line among the three. The beam can eventually be concentrated on the laser processing module 30 to ensure the energy density of the laser processing, thereby improving the processing speed and accuracy.

[0031] Furthermore, referring to Figure 2As shown, the module body 11 is provided with a groove, and the frame 12 includes a mounting part 121 connected to the groove and a lens frame 122 connected to the mounting part 121. A lens hole 122a for mounting lenses is formed on the lens frame 122. The lens frame 122 is located in the optical channel 110. The lens hole 122a of the lens frame 122 is connected to the optical channel 110, and the axis s1 of the lens hole 122a is collinear with the central axis s of the optical channel 110. The lens holes 122a of different frames 12 have different sizes to accommodate lenses of different specifications.

[0032] The mounting part 121 of the frame 12 is set in the groove and is connected and fixed to the groove. After the mounting part 121 is set in the groove, its surface is flush with the outer peripheral surface of the module body 11 where the groove is located, so that the frame 12 does not protrude from the module body 11, reducing the space occupied by the frame module 10.

[0033] The lens frame 122 connected to the mounting part 121 is located below the mounting part 121. When the mounting part 121 is set in the groove, the lens frame 122 is placed in the optical channel 110. A lens hole 122a is formed on the lens frame 122 for mounting a lens. The lens is fixed in the lens hole 122a by screws passing through the two sides of the lens frame 122. The lens hole 122a is connected to the optical channel 110, so that the lens in the lens hole 122a can receive the light beam from the optical module 20 and emit the light beam to the laser processing module 30.

[0034] The axis s1 of the lens aperture 122a is collinear with the central axis s of the optical channel 110. This ensures that when changing different frames 12, the axis s1 of the lens aperture 122a of different frames 12 always remains collinear with the central axis s of the optical channel 110. This guarantees the consistency of the height of all frames 12, so that the optical axis of the lenses of different frames 12 is located on the central axis s of the optical channel 110. This maximizes the utilization of the effective light transmission area of ​​the lens, allows light to pass through the optical channel 110 evenly, reduces unnecessary light energy loss, and ensures overall working efficiency.

[0035] In the embodiments of this application, the groove includes a recessed portion 111 recessed on the outer periphery of the module body 11. There are two recessed portions 111, which are arranged opposite to each other along the central axis direction F1 of the optical channel 110. A through groove 112 communicating with the optical channel 110 is formed between the two recessed portions 111. The lens frame 122 of the lens frame 12 is placed in the optical channel 110 through the through groove 112. The mounting portion 121 of the lens frame 12 is connected to the two recessed portions 111 by fasteners.

[0036] The recess 111 is a structure formed on the module body 11 and recessed downward from the outer periphery of the module body 11. A through groove 112 is formed between the two recesses 111 to communicate with the optical channel 110. The mounting part 121 of the frame 12 is located in the recess 111. The lens frame 122 of the frame 12 passes through the through groove 112 and is inserted into the optical channel 110 to place the lens in the lens hole 122a of the lens frame 122 into the optical channel 110.

[0037] Specifically, each of the two recesses 111 is provided with a first mounting hole 111a, and the mounting part 121 of the frame 12 is provided with a second mounting hole 121a that matches the first mounting hole 111a. Fasteners pass through the second mounting hole 121a and the first mounting hole 111a in sequence so that the frame 12 can be detachably connected to the module body 11. For example, the fastener is generally a screw.

[0038] Four first mounting holes 111a are provided on the two recesses 111. Correspondingly, four second mounting holes 121a are provided on the mounting part 121 of the frame 12. The frame 12 is fixed to the recesses 111 of the module body 11 by passing four screws through the second mounting holes 121a and the first mounting holes 111a in sequence, so as to realize the detachable connection of different frames 12.

[0039] As mentioned above, each frame 12 is matched with one lens. Different frames 12 have different sizes of lens apertures 122a to accommodate different lens specifications. The frame 12 and the lens form an integral unit. When replacing the lens, simply insert the frame 12 with the lens installed into the optical channel 110 and then fix it to the recess 111 through the mounting part 121 of the frame 12. Furthermore, after the lenses of different frames 12 are placed in the optical channel 110, the optical axis of the lens always remains collinear with the central axis s of the optical channel 110, that is, the lens is always located at the center of the optical channel 110.

[0040] On the other hand, regarding the heat dissipation structure, refer to Figure 3 As shown, it includes an air inlet 113 and a return outlet 114 disposed on the main body 11 of the module. The air inlet 113 and the return outlet 114 are disposed on two opposite side walls of the main body 11 of the module. The air inlet 113 and the return outlet 114 are both connected to the optical channel 110 of the main body 11 of the module. The air inlet 113 and the return outlet 114 are also connected to the air intake path and the air return path, respectively, so as to form a high-pressure return gas in the optical channel 110 of the main body 11 of the module to achieve heat dissipation.

[0041] Air inlet 113 and return outlet 114 are connected to the air intake path and return air path respectively via air connectors. The air intake path enters the optical channel 110 through air inlet 113 to dissipate heat from the lens and laser processing module 30, and the heat is carried away through the return air path connected to return outlet 114, thus achieving air cooling of the lens and laser processing module 30. Air intake through air inlet 113 and air exhaust through return outlet 114 form a high-pressure return gas for heat dissipation within the optical channel 110.

[0042] Multiple air inlets 113 and multiple return outlets 114 are provided, and the center of the air inlet 113, the center of the return outlet 114 and the center of the optical channel 110 in the same group are arranged in a collinear manner.

[0043] In the embodiments of this application, such as Figure 1 , Figure 3 As shown, the air inlet 113 and the return outlet 114 are arranged laterally opposite each other along the first direction F2, and their centers and the center of the optical channel 110 are located on the same lateral straight line.

[0044] In other embodiments, the air inlet 113 and the return outlet 114 can also be arranged on the second direction F3, that is, the air inlet 113 and the return outlet 114 are arranged opposite each other in the vertical direction; or the air inlet 113 and the return outlet 114 are arranged obliquely opposite each other, as long as the center of the two and the center of the optical channel 110 are on the same straight line. This arrangement is to ensure that the air inlet and outlet are on a straight line, so that the lens of the optical channel 110 can receive the return high-pressure gas to the maximum extent, which has a good heat dissipation effect on the lens.

[0045] Based on this, an optical path relay plate 13 is also provided at the end of the module body 11 near the optical module 20. One end of the optical path relay plate 13 is fixedly connected to the module body 11, and the other end is connected to the optical module 20.

[0046] like Figure 2 As shown, mounting holes 130 are provided at the four corners of the optical path relay board 13, and screws passing through the mounting holes 130 are used to fix it to the module body 11.

[0047] In addition, the optical path relay plate 13 is provided with mounting holes 131 for connecting optical modules 20. By providing different mounting holes 131 on different optical path relay plates 13, different optical modules 20 can be matched. For example, the optical module 20 can be a fiber collimator optical path for the 3D printing industry, or a free space optical path for marking applications in the battery industry. By replacing different optical path relay plates 13, it can be used for different optical paths, thus achieving the characteristic of optical path compatibility.

[0048] In summary, the detachable connection between the frame 12 and the module body 11 meets the installation requirements of different lenses, achieving compatibility with various lenses. The quick-change frame 12 allows for the replacement of lenses of various standard sizes. By setting air inlets 113 and return outlets 114 on the module body 11, high-pressure air is generated within the optical channel 110 to dissipate heat from the lenses and laser processing module 30, enabling adaptability to high-power operating conditions. Furthermore, different optical path relay plates 13 can connect to different optical modules 20, allowing the frame module 10 to be applicable to multiple optical paths and meet the needs of multi-optical path applications. The frame 12, heat dissipation structure, and optical path relay plate 13 are all integrated on the module body 11, resulting in a compact layout design for the frame module 10.

[0049] Based on this, such as Figure 4 As shown in the embodiments of this application, a laser processing device is also disclosed, including an optical module 20, a laser processing module 30, and a frame module 10, which is disposed between the optical module 20 and the laser processing module 30, and is any one of the above.

[0050] The light beam emitted from the optical module 20 passes through the lens on the frame 12 and is directed towards the laser processing module 30, which is equipped with a laser head to achieve laser processing.

[0051] This laser processing equipment has the same structure and beneficial effects as the eyeglass frame module 10 in the foregoing embodiments. The structure and beneficial effects of the eyeglass frame module 10 have been described in detail in the foregoing embodiments and will not be repeated here.

[0052] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art.
