When the head of the array optical fiber is limited by the positioning assembly 150, the positioning part 151 extending to the bearing plate 160 is used for limiting, so as to limit the lateral movement of the head of the array optical fiber. In addition, the bearing plate 160 is located below the positioning part 151, so as to ensure the stable support of the head of the array optical fiber. The pressing assembly 140 is used for pressing the top of the head of the array optical fiber by the pressing plate after the assembly of the optical fiber array is completed, so as to ensure the stable connection of the optical fiber array after the assembly is glued. In the above manner, when the optical fiber array is assembled, the head of the optical fiber array can be positioned and pressed, so as to improve the yield and efficiency of product production.

[0027] In optional embodiments of the present application, two positioning assemblies 150 are provided, and the two positioning assemblies 150 are symmetrically arranged and form two positioning portions 151 above the bearing plate 160.

[0028] In the above manner, when assembling the fiber array, the fiber array assembly jig 100 can be adapted to single-head fiber arrays and double-head fiber arrays, which is conducive to reducing the operation difficulty, improving the operation efficiency, and shortening the processing cycle.

At the same time, the fixing block 158 and the second sliding block 154 are connected by the first fastener. After the spacing adjustment between the two second sliding blocks 154 is completed, the second sliding block 154 does not need to be adjusted again, and only the extension arm 156 needs to be directly installed and fixed by the fixing block 158. The first fastener and the second fastener are connected by bolts, which facilitates the installation and disassembly of the fixing block 158 and also ensures the reliability of the connection.

[0033] As shown in Figure 3 The positioning portion 151 is provided with a limiting protrusion 1512 for limiting the depth of the head of the array optical fiber inserted into the positioning portion 151.

After the assembly of the optical fiber array is completed, the shaping process is needed, then the stand 144 can be driven to slide relative to the first positioning block 120 by the screw adjusting knob 142, so that the pressing plate clamped on the stand 144 can press and fix the optical fiber array.

[0037] As shown in Figure 4 and Figure 5 , the first positioning block 120 is further provided with a sliding groove 121, a push block 122 is slidably arranged in the sliding groove 121, the push block 122 is provided with a limiting hole 1222 on the side facing the bearing plate 160, an elastic member is arranged in the limiting hole 1222, one end of the elastic member elastically abuts against the bearing plate 160, the other end of the elastic member elastically abuts against the push block 122, and the side of the push block 122 away from the bearing plate 160 abuts against the stand 144.

[0038] Specifically, the push block 122 slidably arranged in the sliding groove 121 is pushed to slide away from the bearing plate 160 under the elastic force of the elastic member. In this way, only the two ends of the transmission rod 143 abut against the connecting rod 145 and the telescopic rod, respectively, and the one end of the transmission rod 143 is always in stable contact with the telescopic rod and the other end is always in stable contact with the connecting rod 145 under the action of the elastic member, to ensure the reliability of transmission. In addition, the elastic member is arranged in the limiting hole 1222 to avoid the elastic member from being skewed under stress, to ensure the reliability of mutual cooperation.

[0042] Specifically, in the assembly of the optical fiber array, in order to avoid the influence of the cable of the optical fiber on the assembly of the optical fiber array, the optical fiber is limited by the wire clamping groove 124, and the positioning of the optical fiber is realized by cooperation of the wire pressing plate 125, so as to avoid the optical fiber length being too long to have a dragging feeling on the head of the optical fiber array, thereby ensuring the reliability during assembly.

[0043] As shown in Figure 5 , the first positioning block 120 is further provided with a magnetic attraction block 126 corresponding to the free end of the wire pressing plate 125, which is used for attracting the free end of the wire pressing plate 125.
