Description

Technical Field

[0001] This utility model relates to the technical field of optical fiber end-face inspection, and more specifically, to a coupler, a laser device, and a laser. Background Technology

[0002] In existing technologies, during laser therapy, if the incident end face of the output fiber of the treatment head, where it connects to the coupler, is burned without timely detection, it will further damage expensive optical components such as the coupler's explosion-proof plate and focusing lens, and will also affect the treatment effect. Therefore, a solution is urgently needed to ensure that the burning of the incident end face of the output fiber of the treatment head can be detected in a timely manner. Utility Model Content

[0003] The first objective of this invention is to provide a coupler to solve the technical problem in the prior art that the incident end face of the output optical fiber of the laser device cannot be detected in time during the use of the laser device.

[0004] The coupler provided by this utility model includes a main body and a detection component and an output head disposed at the output end of the main body. The detection component includes a base, which is fixedly connected to the main body. The base is provided with a through hole for emitting laser light. The output head is provided with an output optical fiber, and the incident end face of the output optical fiber is located in the through hole. The base is also provided with an infrared emitter and an infrared receiver, which are disposed opposite to each other, and the infrared light emitted by the infrared emitter can pass through the through hole.

[0005] Furthermore, the laser output from the main body, the through hole, and the incident end face of the output optical fiber are coaxially arranged, and the infrared light emitted by the infrared emitter can pass through the laser output from the main body.

[0006] Furthermore, both the infrared emitter and the infrared receiver are arranged perpendicular to the axial direction of the through hole, and the axis of the infrared light emitted by the infrared emitter is perpendicular to and intersects the axis of the through hole.

[0007] Furthermore, the base is provided with a first mounting hole and a second mounting hole that penetrate the outer wall of the base and the wall of the through hole. The infrared transmitter is fixedly installed in the first mounting hole, and the infrared receiver is fixedly installed in the second mounting hole.

[0008] Furthermore, along the circumference of the through hole, the base is also provided with three adjusting members. The three adjusting members are adjustable in radial position along the through hole, and one end of each of the three adjusting members protrudes into the through hole and abuts against the incident end of the output optical fiber.

[0009] Furthermore, the adjusting component is a ball-headed set screw, and the base is also provided with three adjusting holes that penetrate its outer side wall and the wall of the through hole, with the three ball-headed set screws respectively disposed in the three adjusting holes.

[0010] Furthermore, the base is a substrate, and the detection component also includes an output flange. The substrate is located between the output end of the main body and the output flange, and the three are fixedly connected.

[0011] Furthermore, the main body includes a housing and a focusing tube, the focusing tube being fixedly disposed at the output end of the housing, and a focusing lens being disposed inside the focusing tube; the output end of the focusing tube is also provided with an explosion-proof bracket, the explosion-proof bracket being provided with an explosion-proof plate, and the explosion-proof plate being coaxially disposed with the focusing lens.

[0013] The coupler provided by this invention, under normal circumstances—that is, when the incident end face of the output fiber of the output head is not burned—maintains a constant time interval between the emission of infrared light by the infrared emitter and the reception of infrared light by the infrared receiver. However, if the incident end face of the output fiber is burned during use, particles and dust will appear in the air near the incident end face. In this case, the time interval between the emission of infrared light by the infrared emitter and the reception of infrared light by the infrared receiver will change. Based on this, the operator can promptly check and adjust the output head and other related components of the coupler. In other words, the coupler provided by this invention can identify whether the incident end face of the output fiber is burned in real time, allowing the operator to check and adjust it promptly, thereby effectively preventing damage to other components and ensuring the accuracy of the laser output from the coupler.

[0014] The second objective of this invention is to provide a laser device that solves the technical problem in the prior art where it is impossible to detect in a timely manner the burn-out end face of the output optical fiber of the laser device output head during the use of the laser device.

[0028] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0029] This embodiment provides a coupler, such as Figures 1 to 3 As shown, the coupler includes a main body 100 and a detection component and an output head 300 disposed at the output end of the main body 100. The detection component includes a base, which is fixedly connected to the main body 100. The base is provided with a through hole 211 for emitting laser light. The output head 300 is provided with an output optical fiber 310, and the incident end face of the output optical fiber 310 is located in the through hole 211. The base is also provided with an infrared emitter 220 and an infrared receiver 230, which are arranged opposite to each other, and the infrared light emitted by the infrared emitter 220 can pass through the through hole 211.

[0030] The coupler provided in this embodiment, under normal circumstances—that is, when the incident end face of the output optical fiber 310 of the output head 300 is not burned—maintains a constant time interval between the emission of infrared light from the infrared emitter 220 and the reception of infrared light by the infrared receiver 230. However, if the incident end face of the output optical fiber 310 is burned during use, particles and dust will appear in the air near the incident end face. In this case, the time interval between the emission of infrared light from the infrared emitter 220 and the reception of infrared light by the infrared receiver 230 will change. Based on this, the operator can promptly inspect and adjust the output head 300 and other related components of the coupler. In other words, the coupler provided in this embodiment can identify in real time whether the incident end face of the output optical fiber 310 is burned, allowing the operator to check and adjust it promptly, thereby effectively preventing damage to other components and ensuring the accuracy of the laser output from the coupler.

[0031] Specifically, in this embodiment, the laser output from the coupler body 100, the through-hole 211 of the base, and the incident end face of the output optical fiber 310 are coaxially arranged, allowing the infrared light emitted by the infrared emitter 220 to pass through the laser output from the body 100. With this arrangement, the infrared light emitted by the infrared emitter 220 can pass through the central region of the through-hole 211, and the distance to each region within the through-hole 211 is not too far. Therefore, based on the propagation time of the infrared light, it is possible to detect in a timely manner whether there are changes in the composition of the air at various points within the through-hole 211, and further check to determine whether the incident end face of the output optical fiber 310 has been burned.

[0032] More specifically, in this embodiment, both the infrared emitter 220 and the infrared receiver 230 are arranged perpendicular to the axial direction of the through hole 211, and the axis of the infrared light emitted by the infrared emitter 220 is perpendicular to and intersects the axis of the through hole 211. With this arrangement, because the infrared light has a short propagation distance, the detection time is shorter, and the detection is more timely. Of course, in other embodiments of this application, the axis of the infrared light emitted by the infrared emitter 220 may only intersect the axis of the through hole 211 but not be perpendicular to it.

[0033] Specifically, in this embodiment, as Figure 1 As shown, the base is provided with a first mounting hole 212 and a second mounting hole penetrating its outer wall and the through hole 211. The infrared transmitter 220 is fixedly mounted in the first mounting hole 212, and the infrared receiver 230 is fixedly mounted in the second mounting hole. More specifically, the infrared transmitter 220 and the infrared receiver 230 can be fixed by interference fit with the corresponding mounting holes or by adhesive application.

[0034] In this embodiment, continue as follows Figure 1 As shown, along the circumference of the through hole 211, the base is also provided with three adjusting members. The radial position of the three adjusting members is adjustable along the through hole 211, and one end of each of the three adjusting members protrudes into the through hole 211 and abuts against the incident end of the output optical fiber 310. In this configuration, by adjusting the length of the three adjusting members protruding into the through hole 211 radially, the position of the incident end of the output optical fiber 310 can be adjusted. Moreover, in addition to adjusting the position of the incident end of the output optical fiber 310, the three adjusting members can also position and limit the incident end of the output optical fiber 310, ensuring that it is reliably located at the target position.

[0035] Specifically, in this embodiment, the adjusting component is a ball-headed setter wire 230, and the base is also provided with three adjusting holes penetrating its outer wall and the wall of the through hole 211. The three ball-headed setter wires 230 are respectively disposed in the three adjusting holes. This arrangement minimizes damage to the incident end of the output optical fiber 310 because the tip of the ball-headed setter wire 230 is relatively smooth. Of course, in other embodiments of this application, the adjusting component is not limited to the ball-headed setter wire 230, but can also be other structural forms, as long as it can be installed in the adjusting hole in an adjustable position and fix the incident end of the output optical fiber 310 at the target position.

[0036] In this embodiment, as Figures 1 to 3As shown, the base is a substrate 210, which can be, for example, a copper plate. The detection assembly also includes an output flange 320. The substrate 210 is located between the output end of the main body 100 and the output flange 320, and the three are fixedly connected. The base adopts a plate structure, which occupies less space and has a more compact structure. Of course, in other embodiments of this application, the base is not limited to the form of a plate, as long as it is provided with necessary through holes 211, mounting holes, and adjustment holes, etc.

[0037] In this embodiment, as Figures 1 to 3 As shown, the main body 100 includes a housing 110 and a focusing tube 120. The focusing tube 120 is fixedly installed at the output end of the housing 110, and a focusing lens 130 is installed inside the focusing tube 120. An explosion-proof bracket 140 is also installed at the output end of the focusing tube 120. An explosion-proof sheet 150 is installed on the explosion-proof bracket 140, and the explosion-proof sheet 150 is coaxially installed with the focusing lens 130.

[0038] In this embodiment, the coupler may also be equipped with an alarm device to issue an alarm when the time between the infrared transmitter 220 emitting infrared light and the infrared receiver 230 receiving the infrared light exceeds the normal time range, so as to remind the operator to check and adjust in time. The structure and principle of the alarm device are mature existing technologies, so they will not be described in detail here.

[0039] This embodiment also provides a laser device, including a laser body and the aforementioned coupler, wherein the input end of the coupler body 100 is connected to the output end of the laser body. This laser device, having the aforementioned coupler, possesses all the beneficial effects of the coupler, which will not be elaborated further here.

[0040] This embodiment also provides a laser, including a laser body, a detection component and an output head 300 disposed at the output end of the laser body. The detection component includes a base, which is fixedly connected to the laser body, and the base is provided with a through hole 211 for emitting laser light. The output head 300 is provided with an output optical fiber 310, the incident end face of which is located within the through hole 211. The base is also provided with an infrared emitter 220 and an infrared receiver 230, which are disposed opposite to each other, and the infrared light emitted by the infrared emitter 220 can pass through the through hole 211. This laser, having the same detection component as the coupler described above, has all the beneficial effects of the coupler described above, which will not be repeated here.

[0041] In summary, this embodiment provides a coupler, a laser device, and a laser. The laser device includes a coupler, and both the laser and the coupler include a detection component for detecting whether the incident end face of the output optical fiber 310 of the output head 300 is burned. Specifically, by adding an infrared emitter 220 and an infrared receiver 230, the time difference between infrared light reception and emission is monitored. When the time difference changes, it is determined that an abnormality has occurred at the incident end face of the output optical fiber 310, thereby reminding the operator to make timely adjustments. This can effectively avoid damage to other devices and ensure the accuracy of the output laser.
