Description

Technical Field

[0001] The utility model specifically relates to the technical field of laser coupling, in particular to a coupling device for an invisible light laser optical path and a visible light optical path. Background Art

[0002] Laser is the light emitted by atoms under stimulation, hence the name "laser". Laser is the energy released in the form of photons when electrons in atoms absorb energy and jump from low energy level to high energy level, and then fall back from high energy level to low energy level. Since lasers other than visible light wavelengths cannot be seen by the naked eye, various laser cutting and heating equipment will couple visible light such as red light and green light with invisible lasers before use, and use visible light to indicate the transmission path of the laser.

[0003] Currently, most visible light indicator lights are fixed on the outside of the coupler, and the emitted light is coupled with the laser only after multiple reflections from the lens. The landing point of the light is adjusted by adjusting the angle of the lens. The optical path structure is complex, and the position of the indicator light spot is difficult to accurately couple with the position of the laser spot, resulting in the inability to perform precise laser heating. In addition, the adjustment steps are cumbersome, and the operation is time-consuming and laborious. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-7The embodiment of the utility model provides a coupling device of an invisible laser optical path and a visible light optical path, comprising a main body 2, and a cavity is arranged inside the main body 2, a visible light indicator light mounting seat 9 is arranged in the cavity inside the main body 2, and a visible light indicator light 91 is fixedly installed inside the visible light indicator light mounting seat 9, and a fixing cap 92 is connected to one end of the visible light indicator light 91, and a threaded gland 6 and a threaded pair 7 are respectively arranged on the side of the main body 2, and a spring 8 is arranged between the threaded gland 6 and the visible light indicator light mounting seat 9;

[0030] The beam combiner mounting assembly comprises an end cap 1, and a hollow beam combiner mounting seat 11 is integrally fixed to the other side of the end cap 1, a lens pressing cover 12 is interference-fitted on the inner side of the beam combiner mounting seat 11, and a beam combiner 13 coupling two optical paths is fixed on the inner side of the lens pressing cover 12;

[0031] The power switch control assembly includes a button control box 3, and two ends of the button control box 3 are respectively connected to a DC connector 4 connected to a power line and a rocker switch 5.

[0032] In this embodiment, there are multiple threaded covers 6 and threaded pairs 7, and two threaded covers 6 and threaded pairs 7 are grouped together. Each group of threaded covers 6 and threaded pairs 7 is correspondingly arranged, and the threaded pairs 7 penetrate the main body 2 and fit with the side of the visible light indicator light mounting seat 9.

[0033] In this embodiment, the threaded gland 6 and the thread pair 7 are respectively connected to the main body 2 through threads, and the two ends of the spring 8 are respectively attached to the side of the shell 81 and the side of the threaded gland 6.

[0034] In this embodiment, the end of the end cap 1 is engraved with an arrow indicating the direction of light irradiation, and the end cap 1 is provided with symmetrical light inlet holes for non-visible light such as carbon dioxide lasers and light outlet holes after combining with visible light on one side close to the beam combiner mounting seat 11.

[0035] In this embodiment, the beam combiner 13 can transmit the optical path of the laser and reflect the optical path of the visible light at 90 degrees. The laser has a wavelength in one of the two industrial laser ranges of 800-1100 nm or 9200-10640 nm.

[0036] In this embodiment, the end cover 1 and the button control box 3 are fixed at two ends of the main body 2 respectively.

[0037] By adopting the above technical solution: through the threaded cooperation between the threaded pair 7 and the main body 2, when the threaded pair 7 is rotated, the threaded pair 7 will move on the inner side of the main body 2, thereby pushing the visible light indicator mounting seat 9 on the inner side of the main body 2 to move, and adjusting the landing point of the visible light emitted from the visible light indicator 91 inside it, without adjusting the reflective mirror, and the visible light indicator 91 is set on the inner side of the main body 2, without the need to install a reflective mirror, the structure is simple, and it is easy to replace internal parts.

[0038] In this embodiment, the wire at the rear end of the visible light indicator 91 passes through the fixing cap 92 and is electrically connected to the DC connector 4 and the rocker switch 5 respectively.

[0039] In this embodiment, the laser light emitted by the laser (not shown) enters from the light inlet and irradiates the side of the beam combiner 13. The laser light refracted by the beam combiner 13 is coupled with the visible light reflected from the surface of the beam combiner 13.

[0040] In this embodiment, the coupled light is emitted in the direction indicated by the arrow at the end of the end cap 1, and the angle between the inclined surface of the beam combiner mounting seat 11 and the horizontal plane is set at 45 degrees.

[0041] In this embodiment, the threaded cover 6 and the threaded pair 7 are respectively located on the outside of the shell 81. The threaded pair 7 is rotated, and the threaded fit between the threaded pair 7 and the main body 2 allows the end of the threaded pair 7 to push the visible light indicator light mounting seat 9 to move, thereby adjusting the landing point of the light emitted by the visible light indicator light 8 on the beam combiner 13.

[0042] In this embodiment, the external power source is connected to the DC connector 4 via a wire (not shown in the figure) to supply power to the visible light indicator light 9 .

[0043] During installation, the main body 2 needs to be installed on the side of the light outlet of the laser (not shown in the figure) first, and the laser line of the laser shines into the inner side of the main body 2 from the light inlet hole.

[0044] The working principle of the utility model is: when in use, Figure 5 , the laser line emitted by the laser located above passes through the light inlet hole and irradiates the beam combiner 13. The laser is refracted by the beam combiner 13 and irradiates from the other side of the beam combiner 13. At the same time, the visible light indicator 91 emits visible light such as red light and green light. The visible light such as red light and green light irradiates the surface of the beam combiner 13 and is reflected. Visible light is emitted at the position of the light outlet hole, and a light spot is formed after irradiating the target position. The reflected visible light such as red light and green light coincides with the refracted invisible laser, that is, the irradiation path of the visible light such as red light and green light irradiated from the light outlet hole is also the irradiation path of the laser line;

[0045] In addition, the visible light indicator light 91 is installed on the inner side of the main body 2, which has a certain protective effect. The visible light such as red light and green light emitted by the main body 2 directly irradiates the surface of the beam combiner 13, and does not need to be coupled after mirror reflection. The structure is simple. The threaded cover 6 and the threaded pair 7 are used to directly adjust the position of the visible light indicator light mounting seat 9. There is no need to adjust the angle of the reflector. It is convenient to find the landing point of visible light such as red light and green light during adjustment. The structure is simple and the operation is very convenient.
