[0032] Please refer to Figure 1 and Figure 10The optical fiber end face packaging device provided by the embodiment of the present application will be described. The optical fiber end face packaging device is used for packaging the optical fiber end face 1110 of the optical fiber device 1000, so that the optical fiber end face 1110 can be protected for a long time, and the parameters of the optical fiber end face 1110 are ensured to be stable. The optical fiber device 1000 can be a high-power optical fiber combiner, a high-power optical fiber coupler, a sensing optical fiber, or the like.

[0033] The optical fiber end face packaging device comprises a device mounting rack 100, an optical fiber positioning seat 200, and a packaging tube positioning seat 300 which are sequentially distributed along a first direction X. The device mounting rack 100 is used for placing the optical fiber device 1000. The optical fiber 1100 of the optical fiber device 1000 penetrates the optical fiber positioning seat 200 along the first direction X, and the optical fiber end face 1110 is located in the packaging tube positioning seat 300.

[0034] It should be noted that the optical fiber end face 1110 is packaged by the optical fiber end face packaging device provided by the present application. The packaging is completed manually. Specifically, the optical fiber device 1000 is placed on the device mounting rack 100 with the optical fiber 1100 facing the optical fiber positioning seat 200, so that the optical fiber 1100 penetrates the optical fiber positioning seat 200 and is adsorbed and fixed by the optical fiber positioning seat 200, and the end face of the optical fiber 1100 extends into the packaging tube positioning seat 300. Then, the packaging tube 2000 is sleeved on the outside of the optical fiber 1100 along the first direction X. The position of the optical fiber end face 1110 is observed to be located at the radial center position and the axial center position of the packaging tube 2000. Finally, the packaging tube 2000 is manually glued at opposite ends to form a packaging glue 3000, so that the optical fiber end face 1110 is packaged in the packaging tube 2000. At this time, the packaging tube 2000 can be adsorbed and positioned by the packaging tube positioning seat 300 to ensure the stability of the gluing. It should be noted that the packaging tube 2000 is a glass round tube, and the staff can observe the position of the optical fiber end face 1110 in the packaging tube 2000 from the outside of the packaging tube 2000.

[0035] The optical fiber end face packaging device in the embodiment of the application, through the arrangement of the device mounting rack 100, the optical fiber positioning seat 200 and the packaging tube positioning seat 300, when the optical fiber end face is packaged, the optical fiber device 1000 can be placed on the device mounting rack 100, the optical fiber 1100 is adsorbed and positioned through the optical fiber positioning seat 200, and the packaging tube 2000 is adsorbed and positioned through the packaging tube positioning seat 300, so as to ensure the position accuracy of the optical fiber end face 1110 inserted into the packaging tube 2000, and the packaging tube positioning seat 300 can also ensure the position stability when the two ends of the packaging tube 2000 are glued, thereby ensuring the packaging accuracy and stability.

In addition, the optical fiber positioning seat 200 and the packaging tube positioning seat 300 are fixed by adsorption, which not only ensures firm positioning, but also will not damage the optical fiber 1100 and the packaging tube 2000.

[0036] In some embodiments, referring to Figure 1 , the optical fiber end face packaging device further comprises a mounting base plate 400, and the device mounting rack 100, the optical fiber positioning seat 200 and the packaging tube positioning seat 300 are sequentially mounted on the mounting base plate 400.

The mounting base plate 400 has a first mounting hole 410, through which the mounting base plate 400 can be mounted on a work platform with a certain height to facilitate the operation of the staff.

[0037] In some embodiments, referring to Figure 1 and Figure 2 , the optical fiber end face packaging device further comprises a fine adjustment mechanism 500, which is used to adjust the position of the packaging tube positioning seat 300 along the first direction X, the second direction Y and the vertical direction, wherein the first direction X, the second direction Y and the vertical direction are perpendicular to each other. In actual application, corresponding to different types and different specifications of optical fiber devices 1000, the number and diameter of the optical fibers 1100 packaged each time may be different, which makes it difficult for the optical fiber end faces 1110 to be located at the center position of the packaging tube 2000. The arrangement of the above-mentioned fine adjustment mechanism 500 can adjust the position of the packaging tube positioning seat 300 along the first direction X, the second direction Y and the vertical direction, so as to adjust the position of the packaging tube 2000 in the first direction X, the second direction Y and the vertical direction, and thereby ensure that the optical fiber end face 1110 can be located at the center position of the packaging tube 2000. In actual operation, the naked eye can be observed together or through a microscope.

[0038] In some embodiments, referring to Figure 1 andFigure 2 The fine adjustment mechanism 500 includes an XYZ manual platform 510. The XYZ manual platform 510, also known as a three-coordinate high-precision moving platform, is a platform capable of precise movement in the X, Y, and Z directions. The XYZ manual platform 510 is a mature structure, and the design of the XYZ manual platform 510 focuses on precision and stability, using advanced manufacturing techniques and materials to ensure the performance and service life of the platform. In this embodiment, the XYZ manual platform 510 is used to adjust the position of the packaging tube positioning seat 300 and the packaging tube 2000 along the first direction X, the second direction Y, and the vertical direction, thereby ensuring the position adjustment accuracy of the packaging tube positioning seat 300 and reducing the use cost. It can be understood that in other embodiments of the present application, a first linear module, a second linear module, and a third linear module can also be provided to adjust the position of the packaging tube positioning seat 300 along the first direction X, the second direction Y, and the vertical direction. Specifically, the packaging tube positioning seat 300 can be installed on the output end of the third linear module, the third linear module can be installed on the output end of the second linear module, and the second linear module can be installed on the output end of the first linear module. The first linear module, the second linear module, and the third linear module can be ball screw mechanisms, screw nut mechanisms, etc.

[0039] In some embodiments, referring to Figure 1 and Figure 2 the packaging tube positioning seat 300 is installed on the top side of the XYZ manual platform 510, and the XYZ manual platform 510 supports the packaging tube positioning seat 300 at a certain height, so that the optical fiber end face 1110 can be inserted horizontally into the packaging tube positioning seat 300, and the position of the packaging tube positioning seat 300 can be fine adjusted by the XYZ manual platform 510.

[0040] In some embodiments, referring to Figure 2 and Figure 3 the packaging tube positioning seat 300 has a receiving groove 310 for accommodating and positioning the packaging tube 2000, and the receiving groove 310 extends through the packaging tube positioning seat 300 along the opposite ends of the first direction X.

[0041] For the convenience of description, the opposite two ends of the accommodating groove 310 are referred to as the first end and the second end. When performing the fiber end face packaging, the fiber device 1000 is first placed on the device mounting frame 100, and the position of the packaging tube positioning seat 300 is adjusted by the fine adjustment mechanism 500, so that the fiber end face 1110 can extend into the accommodating groove 310 from the first end of the accommodating groove 310. Then, the packaging tube 2000 is inserted into the accommodating groove 310 from the second end of the accommodating groove 310, so that the fiber end face 1110 is inserted into the packaging tube 2000. Then, the position of the packaging tube positioning seat 300 is adjusted by the fine adjustment mechanism 500, so that the fiber end face 1110 is located at the center position of the packaging tube 2000. Finally, dispensing is performed at the opposite two ends of the packaging tube 2000 to form the packaging glue 3000. In the embodiment, the accommodating groove 310 penetrates through the opposite two ends of the packaging tube positioning seat 300, so that the packaging tube 2000 can be sleeved outside the fiber end face 1110 after the fiber end face 1110 is positioned, avoiding that the packaging tube 2000 is initially assembled in place, which causes structural interference between the fiber end face 1110 and the packaging tube 2000.

[0042] In some embodiments, referring to Figure 2 and Figure 3 , the first cross section of the accommodating groove 310 is in the shape of a circular arc and is adapted to the packaging tube 2000. The accommodating groove 310 penetrates through the upper side of the packaging tube positioning seat 300, and the first cross section is a cross section perpendicular to the first direction X. The circular arc shape allows the accommodating groove 310 to limit the packaging tube 2000 in the circumferential direction when the packaging tube 2000 is inserted into the accommodating groove 310 from the second end of the accommodating groove 310, so that the packaging tube 2000 does not deviate radially in the accommodating groove 310, ensuring the packaging precision of the packaging tube 2000 and the fiber end face 1110 and the dispensing stability. In addition, the accommodating groove 310 penetrates through the upper side of the packaging tube positioning seat 300, so that the packaging tube 2000 is at least partially exposed, and the user can directly observe the position of the fiber end face in the packaging tube 2000, to ensure the packaging precision.

In this way, the packaging tube 2000 can be adsorbed and fixed at the center position of the accommodating groove 310. In addition, the adsorption holes 320 are distributed along the first direction X, so that the adsorption force on the packaging tube 2000 is uniformly distributed along the first direction X, thereby ensuring the stability of the adsorption of the packaging tube 2000.
