Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0039] The following is based on the attached Figure 1 To the attached Figure 9 The utility model introduces a laser optical fiber protection device and a laser.

[0040] like Figure 1 、 Figure 2 As shown, the laser fiber protection device can connect the laser fiber and detect whether the laser fiber is correctly connected, thereby avoiding the phenomenon of laser damage to the laser fiber and related parts of the laser.

[0041] Specifically, the laser fiber protection device includes a housing 1, a fiber position sensor, and a temperature sensor 3. Housing 1 is provided with a mounting interface 10. One end of the laser fiber serves as an interface end 100, which can be inserted and installed into the mounting structure, thereby connecting the laser fiber to the laser fiber protection device. The laser fiber protection device is mounted on the laser. The laser light generated by the pump source inside the laser can pass through the laser fiber protection device and couple to the interface end 100, thereby transmitting along the laser fiber.

[0042] The optical fiber position sensor and the temperature sensor 3 are both arranged inside the housing 1. The optical fiber position sensor is used to detect whether the interface end 100 is correctly inserted into the installation interface 10, and the temperature sensor 3 is used to detect whether the laser is correctly coupled into the interface end 100. For example, refer to Figure 3 As shown in FIG, when the depth of the interface end 100 inserted into the installation interface 10 is less than the correct depth, the interface end 100 will be incorrectly connected to the installation interface 10. At this time, the fiber optic in-place sensor will detect the incorrect connection and send a relevant signal to the operator through the control component or alarm component connected to the fiber optic in-place sensor. Figure 4 As shown, when the fit between the interface end 100 and the mounting interface 10 is poor (e.g., poor coaxiality), the laser cannot be fully coupled to the interface end 100. This causes a portion of the laser to irradiate the mounting interface 10, causing the temperature inside the housing 1 to rise. In this case, the temperature sensor 3 measures the temperature inside the housing 1 to promptly detect whether the fit between the interface end 100 and the mounting interface 10 is poor. Of course, the temperature sensor 3 can also be connected to a control component or an alarm component to send a relevant signal to the operator.

[0043] By setting up an installation interface 10 to insert the interface end 100 of the laser optical fiber, and setting up an optical fiber position sensor and a temperature sensor 3, it is possible to effectively ensure that the laser optical fiber is correctly connected to the laser through the laser optical fiber protection device, thereby preventing the connection position from being misaligned and avoiding damage to the laser optical fiber and related components of the laser by the laser.

[0044] Specifically, in this embodiment, the optical fiber arrival sensor is preferably a position sensor. The position sensor can detect the position of the interface end 100 in the installation interface 10 along the depth direction of the installation interface 10, thereby accurately reflecting whether the interface end 100 is inserted into the installation interface 10 to a preset depth.

[0045] More specifically, if Figure 3 、 Figure 4As shown, in this embodiment, the shell 1 includes a front cover 11 and a main body 12, and the front cover 11 is arranged on one side of the main body 12. The front cover 11 is provided with a through hole, and the main body 12 is provided with a plug interface. The through hole and the plug interface are coaxially arranged and define the above-mentioned installation interface 10, and the interface end 100 can pass through the through hole and be connected to the plug interface. The plug interface adopts a protruding annular structure 121, which can be correspondingly plugged into the interface end 100. In other words, only when the plug interface is plugged into the interface end 100, the interface end 100 can be at the preset depth in the installation interface 10, thereby meeting the necessary conditions for correct insertion. When the interface end 100 is not at the preset depth in the installation interface 10, it must be in a state of incorrect insertion and connection, and adjustment is required.

[0046] Preferably, the fiber optic in-place sensor utilizes a travel switch 2. When the interface end 100 is correctly inserted into the mounting interface 10, its insertion depth equals the preset depth, causing the interface end 100 to abut against the mounting interface 10, forming a switch. The travel switch 2 is triggered by pressure from the interface end 100. When the insertion depth of the interface end 100 is less than the preset depth, the travel switch 2 is not subjected to pressure or the pressure applied is insufficient to trigger it, rendering the travel switch 2 in an untriggered state. During use, the control component or alarm component indicates whether the travel switch 2 is in a triggered or untriggered state, clearly indicating whether the interface end 100 has met the requirements for correct insertion.

[0047] Of course, since the limit switch 2 generally has only two states, a triggered state and an untriggered state, in some embodiments, when the interface end 100 is correctly inserted into the mounting interface 10, the limit switch 2 may be in the untriggered state due to pressure from the interface end 100, and when the insertion depth of the interface end 100 is less than a preset depth, the limit switch 2 is not subjected to pressure or the pressure is insufficient to trigger, causing the limit switch 2 to be in the triggered state. As long as it can reflect whether the insertion depth of the interface end 100 meets the requirements for correct insertion, it falls within the scope of protection of the present invention.

[0048] Of course, in addition to the above-mentioned travel switch 2, the position sensor may also specifically adopt other contact sensors, or non-contact sensors, such as photoelectric sensors, etc., which are not specifically limited in the present invention.

[0049] Preferably, if Figure 4 As shown, in this embodiment, the detection end of the temperature sensor 3 is disposed within the mounting interface 10, thereby conveniently detecting temperature changes within the mounting interface 10 and promptly issuing an alarm for temperature anomalies to prevent damage to related components. Specifically, a sensor mounting slot 122 is provided in the body 12, with the end of the mounting slot being adjacent to the plug-in interface, thereby allowing the detection end of the temperature sensor 3 to be located within the mounting interface 10.

[0050] Further preferably, the body 12 is further provided with more sensor mounting slots 122 for mounting the aforementioned travel switch 2. Furthermore, the sensor mounting slots 122 are provided on the side of the body 12 where the plug interface is provided, i.e., on the side connected to the front cover 11, thereby facilitating the maintenance and replacement of each sensor by removing the front cover 11.

[0051] like Figure 5 As shown, in this embodiment, a protective mirror 6 is further provided in the housing 1. The protective mirror 6 includes a lens 61. When the interface end 100 is inserted into the mounting interface 10, the lens 61 can isolate the interface end 100 and the laser. The laser can pass through the lens 61 and couple to the interface end 100, thereby not affecting the transmission of the laser and protecting the pump source and other structures inside the laser.

[0052] like Figure 5 、 Figure 6 As shown, the housing 1 is provided with a limit groove 123, and the protective mirror 6 is limited and set in the limit groove 123, thereby ensuring that the lens 61 can be coaxially arranged with the above-mentioned interface end 100, plug interface, etc. The housing 1 also includes a rear cover 13, which is detachably mounted in the limit groove 123, thereby pressing and fixing the protective mirror 6 in the limit groove 123.

[0053] Preferably, if Figure 7 、 Figure 8 As shown, a protective mirror in-place sensor 4 is also provided within the housing 1. The protective mirror in-place sensor 4 is used to detect whether the protective mirror 6 is properly installed in the installation slot. Specifically, in this embodiment, the protective mirror in-place sensor 4 utilizes a through-beam photoelectric switch. The protective mirror 6 includes a frame 62 fixedly connected to a lens 61. When the protective mirror 6 is properly installed, the frame 62 blocks the detection light from the through-beam photoelectric switch, thereby indicating that the protective mirror 6 is properly installed. Of course, in other embodiments, similar position sensors such as a travel switch 2 may also be used, and this also falls within the scope of protection of the present utility model.

[0054] Furthermore, the housing 1 is preferably provided with a third sensor mounting slot 122 for correspondingly mounting the aforementioned protective lens in-place sensor 4. The protective lens in-place sensor 4 can also be conveniently repaired or replaced by removing the front cover 11. Of course, more sensors and more sensor mounting slots 122 may be provided, and this is not specifically limited in the present invention.

[0055] like Figure 8 、 Figure 9As shown, the inner wall of the retaining groove 123 is provided with a selector screw 5, and the side wall of the mirror frame 62 is provided with an embedded portion 621. Only when the protective mirror 6 is in place can the selector screw 5 be inserted into the embedded portion 621 to retain the protective mirror 6. In this way, when installing the protective mirror 6, the selector screw 5 can be used to determine whether the protective mirror 6 is in place simply by feeling whether the selector screw 5 rebounds, further facilitating installation.

[0056] The present invention also provides a laser device, which includes a laser fiber and the aforementioned laser fiber protection device, wherein the laser fiber is detachably connected to the mounting interface 10 of the laser fiber protection device. By providing the mounting interface 10 on the laser fiber protection device for inserting the interface end 100 of the laser fiber, and providing a fiber position sensor and a temperature sensor 3, it is possible to effectively ensure that the laser fiber is correctly connected to the laser device through the laser fiber protection device, thereby preventing the phenomenon of connection position misalignment and avoiding damage to the laser fiber and related components of the laser caused by the laser.

[0057] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
