[0034] This embodiment provides a light combining device 1, as Figure 1 , 6 shown. The light combining device 1 includes a visible light module 10 and a light combining component 20. The visible light module 10 is used to emit a visible light beam to the light combining component 20;

[0035] The light combining component 20 is located at the visible light emitting end of the visible light module 10 and the laser emitting end 2001 of the laser 200, and is used to adjust the coaxiality of the visible light beam and the laser beam.

[0036] The light combining device 1 mainly includes a visible light module 10 and a light combining component 20. The visible light module 10 is used to emit a visible light beam and guide it to the light combining component 20. The light combining component 20 is installed between the emitting end of the visible light module 10 and the laser emitting end 2001 of the laser 200, and can accurately adjust the coaxiality of the visible light beam and the laser beam, so that the visible light beam and the laser beam can achieve coaxial transmission in a specific space. When adjusting the optical path, the operator can judge the direction of the laser beam by observing the path of the visible light beam, which greatly improves the operation safety.

[0037] The visible light module 10 is precisely adjusted in angle by the light combining component 20, so that the visible light beam can be flexibly transformed in three-dimensional space, so as to achieve perfect coaxiality with the laser beam at a specified position. At the same time, the light combining component 20 can not only adapt to various types of lasers 200, but also can be quickly installed and disassembled, improving the versatility and operation convenience of the device.

[0038] In some embodiments, as Figure 1 , 3 shown. The light combining component 20 includes a light combining adjustment block 21. The visible light module 10 is arranged on the top of the light combining adjustment block 21, and is used to fix and adjust the spatial angle of the visible light module 10.

[0039] By means of the light combining adjustment block 21, the visible light module 10 can flexibly adjust its angle and position in three-dimensional space to ensure that the emitted visible light beam can be precisely coaxial with the laser beam emitted by the laser 200 in space. During the adjustment process, the light combining adjustment block 21 can be finely adjusted in the X, Y, and Z directions. Such flexibility makes the optical path adjustment more convenient and efficient, avoiding the multiple repeated debugging caused by optical path deviation in the traditional dimming method.

[0040] The light combining adjustment block 21 can maintain the stability and reliability of the visible light module 10, preventing the optical path from shifting due to mechanical vibration or other external forces during the adjustment process; through the precise adjustment of the light combining adjustment block 21, the visible light module 10 enables the visible light beam to always maintain coaxiality with the laser beam, thereby improving the dimming efficiency and accuracy of the entire light combining device 1, greatly reducing the difficulty and risk during the dimming process, and having a light combining structure with both practicality and safety.

[0041] In some embodiments, as Figure 1 、 3 shown. The light combining assembly 20 further includes a light combining head 22 and a light combining base 23. The top of the light combining head 22 is softly connected to the light combining adjustment block 21, and the light combining head 22 is firmly connected to the light combining base 23.

[0042] The top of the light combining head 22 is connected to the light combining adjustment block 21 in a soft connection manner, which can not only effectively absorb and relieve minor mechanical vibrations, but also prevent the optical path from shifting due to external forces during the adjustment process while maintaining the precise positioning of the visible light module 10, thereby improving the stability and adjustment accuracy of the optical path; the light combining head 22 and the light combining base 23 are firmly connected. Specifically, the light combining head 22 can firmly fix the laser 200 on the light combining base 23 through fixing screws 223 or other fasteners, realizing the overall stability of the light combining assembly 20, ensuring that after the optical path adjustment is completed, reliable mechanical connections can be maintained between the components, and avoiding optical path deviation caused by loosening or displacement during use, especially suitable for scenarios requiring high-precision optical path adjustment, such as laser engraving, marking and other high-precision processing fields, effectively improving the use efficiency and dimming safety of the laser device 2.

[0043] In some embodiments, as Figure 2 、 3 、5 shown. The side of the light combining base 23 firmly connected to the light combining head 22 is provided with an inclined surface 231. A filter 25 is arranged on the inclined surface 231, and a first through hole 232 is transversely opened along the filter 25. The laser emission end 2001 is located on one side of the first through hole 232;

[0044] The combining optical head 22 is vertically provided with a second through hole 221 and horizontally provided with a third through hole 222. The second through hole 221 and the third through hole 222 are opposite to the filter 25;

[0045] The visible light module 10 is located above the second through hole 221.

[0046] The side of the combining optical base 23 tightly connected to the combining optical head 22 is provided with an inclined surface 231 for mounting the filter 25. The setting angle of the filter 25 enables it to simultaneously meet the requirements of transmission and reflection of light beams with different wavelengths. Usually, its angle with the horizontal plane is 45°, which can achieve the transmission of the laser beam and the reflection of the visible light beam, thereby effectively combining the two light beams together; the filter 25 is horizontally provided with a first through hole 232, and the laser emission end 2001 of the laser 200 is located on one side of the through hole, and the laser beam can pass through the filter 25 and continue to propagate without interference.

[0047] At the same time, the combining optical head 22 is vertically provided with a second through hole 221 and horizontally provided with a third through hole 222. The second through hole 221 and the third through hole 222 are respectively opposite to the filter 25, allowing the visible light and the laser beam to simultaneously pass through the combining optical head 22 in different directions and converge and adjust at the position of the filter 25. Specifically, the visible light module 10 is located above the second through hole 221. Through the precise adjustment of the combining optical adjustment block 21, the visible light beam can enter from the second through hole 221 and be reflected in the direction of the third through hole 222 when passing through the filter 25, and remain coaxial with the laser beam.

[0048] The structure provided in this embodiment can effectively control and guide light beams with different wavelengths through the filter 25, thereby realizing efficient beam combination. The setting of the inclined surface 231 and the filter 25 can make the best use of the physical properties of light, enabling the laser and the visible light to accurately coincide in space and avoiding the optical path deviation caused by improper angles in the traditional method.

[0049] In addition, the first through hole 232, the second through hole 221, and the third through hole 222 enable the entire beam combining device 1 to adapt to the installation requirements of different models of lasers 200, and different types of lasers 200 can achieve precise beam combination with visible light through simple adjustment.

[0050] In some embodiments, the angle between the filter 25 and the horizontal plate is 45° or 135°.

[0051] The angle between the filter 25 and the horizontal plane is 45° or 135°, which can maximize the use of optical reflection and transmission principles to achieve optical path coaxiality. When the filter 25 is at an angle of 45° or 135° to the horizontal plane, the visible light beam will be reflected when passing through the filter 25, while the laser beam can be transmitted through the filter 25, so that the two beams of light form a precise coaxial relationship in space.

[0052] The angle selection of the filter 25 not only affects the reflection and transmission of the light beam, but is also closely related to the mechanical structure and installation method of the entire light combining system; the filter 25 is usually installed on the inclined surface 231 of the light combining seat 23, and cooperates with the fine adjustment of the light combining adjustment block 21, so that light beams of different wavelengths can achieve an ideal light combining effect in the same space. In specific implementations, operators can select the installation angle of the filter 25 according to actual needs to adapt to different application scenarios. For example, for most conventional applications, an angle of 45° or 135° can provide the best light combining effect.

[0053] In some embodiments, the filter 25 is used to transmit the laser light emitted by the laser 200 and reflect the visible light emitted by the visible light module 10 .

[0054] The filter 25 can transmit the laser beam emitted by the laser 200 and simultaneously reflect the visible light beam emitted by the visible light module 10. This optical property is based on the selective reflection and transmission capabilities of the filter 25 for light beams of different wavelengths. Generally, the filter 25 is composed of multiple layers of dielectric films, and the thickness and refractive index of each layer are precisely calculated and designed to produce the expected optical effect at a specific wavelength.

[0055] When the laser beam emitted by the laser 200, such as an infrared laser with a wavelength of 10600nm, is incident on the filter 25 at a certain angle, the filter 25 can effectively transmit the light beam of this wavelength, so that it continues to propagate in the original direction. As for the visible light emitted by the visible light module 10, the red light with a wavelength of 650nm, the filter 25 can reflect it to a specific direction. In this way, the laser beam and the visible light beam can form a spatial intersection at the filter 25, and finally achieve the coaxiality of the two beams of light. Not only does it simplify the optical path adjustment process, but it also enables the operator to determine the actual direction of the laser by observing the propagation path of the visible light, greatly improving the safety of the operation.

[0056] In some embodiments, Figure 3 , 4 The top of the light combining adjustment block 21 is provided with an adjustment screw 211 and a fixing spring screw 212 . The fixing spring screw 212 is used for the flexible connection between the light combining adjustment block 21 and the light combining head 22 . The adjustment screw 211 is used for adjusting the spatial angle of the visible light module 10 .

[0057] The fixing spring screw 212 is used to softly connect the light combining adjustment block 21 and the light combining head 22. This soft connection method can absorb and relieve part of the vibration under the condition of mechanical vibration or external force impact, so as to maintain the stability and accuracy of the optical path. The soft connection structure can effectively reduce the influence of mechanical stress on the optical path adjustment, avoid the optical path deviation caused by the tiny displacement of the optical elements, and thus ensure the stable transmission of the light beam.

[0058] The adjustment screw 211 is located at the top of the light combining adjustment block 21, and its main function is to accurately adjust the spatial angle of the visible light module 10. By rotating the adjustment screw 211, the operator can flexibly change the angle and position of the visible light module 10 to ensure that the emitted visible light beam can accurately coincide with the laser beam of the laser 200 in space. This design allows the visible light module 10 to make fine adjustments in the X, Y, and Z directions, so as to achieve precise positioning and adjustment in three-dimensional space. This adjustment mechanism provides convenience for the accurate alignment of the optical path, enables the operator to complete complex optical path adjustment tasks in a short time, and can visually observe the change of the visible light beam during the light adjustment process, greatly improving the efficiency and accuracy of the adjustment.

[0059] In addition, the combined use of the adjustment screw 211 and the fixing spring screw 212 makes the entire light combining adjustment block 21 have both good stability and certain adjustment elasticity. While providing the angle adjustment function, the adjustment screw 211 can control the acting force of the fixing spring screw 212 by adjusting its tightness, so as to further optimize the connection state between the light combining adjustment block 21 and the light combining head 22. This design not only improves the mechanical stability of the light combining device 1, but also effectively avoids the optical path deviation problem caused by the loosening of the screw.

[0060] In some embodiments, as Figure 4 shown. A locking set screw 213 is also provided on the side of the light combining adjustment block 21, and the locking set screw 213 is used to fix the visible light module 10.

[0061] A locking set screw 213 is also provided on the side of the light combining adjustment block 21, and the locking set screw 213 is used to fix the position and angle of the visible light module 10. The locking set screw 213 is a simple and effective mechanical fixing device, which can achieve firm fixing or flexible adjustment of the visible light module 10 by tightening or loosening. In this embodiment, the locking set screw 213 can not only ensure that the visible light module 10 remains stable after adjustment, but also be conveniently released and re-locked when fine adjustment is needed, thus providing great convenience for the accurate adjustment of the optical path.

[0062] The function of the locking set screw 213 is mainly reflected in two aspects: one is to fix the visible light module 10 to ensure that its position does not shift due to external forces or vibrations after the dimming is completed; the other is to allow the operator to appropriately adjust the position of the visible light module 10 during the fine-tuning process by adjusting the tightness of the locking set screw 213. The position and angle of the visible light module 10 are key factors affecting the optical path coaxiality and beam quality. The design of the locking set screw 213 provides the operator with a means of fine adjustment, enabling precise control at the micron level during the adjustment process, thereby ensuring the perfect coincidence of the visible light and laser beams in space.

[0063] In specific implementation, the operator can first roughly adjust the position of the visible light module 10 by adjusting the screw 211, and then use the locking set screw 213 to perform the final precise positioning and fixing of the module. The tightening force of the locking set screw 213 can be adjusted according to specific adjustment requirements to ensure that sufficient stability is provided during the fixing process without exerting excessive pressure on the visible light module 10, avoiding damage or deformation of the optical device. Such a design not only ensures the flexibility of adjustment but also improves the durability and reliability of the entire device.

[0064] In addition, the combination of the locking set screw 213 and the side structure design of the light combining adjustment block 21 makes the adjustment process of the entire light combining device 1 more efficient and convenient. The operator can quickly lock the visible light module 10 after the adjustment is completed without repeated adjustment, greatly improving the efficiency of the optical path adjustment. This design is particularly practical during the use of laser devices, especially in application scenarios where the optical path needs to be frequently adjusted. It can significantly reduce the adjustment time and ensure the long-term stability of the optical path.

[0065] In some embodiments, such as Figure 1 、 5 shown. The light combining component 20 further includes a light combining locking block 24, and the light combining locking block 24 is fixedly connected to the light combining seat 23; the light combining locking block 24 is used to fixedly connect the laser emission end 2001 of the laser 200 to the light combining seat 23.

[0066] The light combining locking block 24 is connected to the light combining seat 23 by means of a fixed connection, fixedly connecting the laser emission end 2001 of the laser 200 to the light combining seat 23, thereby ensuring that the laser 200 can maintain a stable position and optical path consistency when emitting laser light. It can effectively prevent the laser 200 from shifting in position due to vibrations or other external forces during operation, thereby ensuring the coaxiality and stability of the laser beam and the visible light beam in space.

[0067] The optical combination locking block 24 and the laser emission end 2001 of the laser 200 adopt an accurate mechanical connection method, and this fastening connection can ensure the firmness and reliability of the laser 200 during operation. Specifically, the optical combination locking block 24 can firmly fix the laser 200 on the optical combination base 23 through fastening screws 241 or other fasteners, which can not only provide stable mechanical support, but also effectively reduce the tiny displacement caused by thermal expansion or mechanical vibration when the laser 200 is working.

[0068] This embodiment provides a laser device, such as Figure 6 shown. A laser device 2, and the laser device 2 includes the above-mentioned optical combination device 1.

[0069] The laser device 2 integrates the optical combination device 1 described above, and can accurately combine the visible light beam and the laser beam, realizing efficient adjustment and calibration of the optical path. The laser device 2 includes a laser 200 and an optical combination component 20, realizing the precise coaxial and stable transmission of the laser beam and the visible light beam.

[0070] Specifically, the optical combination device 1 in the laser device 2 can effectively combine the laser beam emitted by the laser 200 and the visible light beam emitted by the visible light module 10 at the filter 25. The filter 25 can transmit the laser beam and reflect the visible light beam, so that the two beams of light are combined in the same optical path. The optical combination adjustment block 21 is used to finely adjust the position and angle of the visible light module 10 to ensure that the two beams of light achieve the best coaxiality at a specific position. In practical applications, the operator can judge and adjust the path of the laser beam by observing the position and direction of the visible light beam, which greatly simplifies the optical path adjustment process and avoids the potential danger caused by the direct irradiation of the laser beam.

[0071] The fastening connection between the optical combination locking block 24 and the optical combination base 23 ensures the stability between the laser emission end 2001 of the laser 200 and the optical combination device 1, and avoids the problem of optical path deviation caused by external force or vibration during operation. This tight mechanical connection enables the entire laser device 2 to maintain high precision while being able to withstand large mechanical loads and frequent optical path adjustment operations. The optical combination component 20 also makes the laser device 2 highly versatile and scalable, and can be applied to various types of lasers 200 and optical systems.

[0072] In addition, the laser device 2 realizes the visual operation of laser dimming by integrating the visible light module 10 and the optical combination device 1, making the use of the device safer and more efficient. The operator can directly calibrate and adjust the optical path through the visible light module 10 without directly contacting the high-energy laser. This not only improves the operation safety of the laser device 2, but also greatly reduces the dimming time and error, effectively improving the work efficiency and product processing precision.

[0073] The above are only the specific implementation manners of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
