[0054] During the precise docking movement process, a clamping hoop clamping assembly and a fine adjustment frame are used, which can solve the problems of the existing ferrule 111 being difficult to insert and the accuracy being difficult to control.
[0055] Furthermore, the clamping assembly includes two first mounting blocks 813 slidably mounted in the slide groove 220 and facing each other, and mounting shafts 816 are respectively provided on the opposite surfaces of the two first mounting blocks 813, and two rotatable sleeves 815 are provided on each mounting shaft 816, and the two sleeves 815 are correspondingly connected with two openable and closable transmission covers 814, and the cross-sections of the two transmission covers 814 are both right-angle fan-shaped structures, and a plurality of first jackets 818 are provided on the contact end surfaces of the two transmission covers 814, and the inner sides of the front and rear ends of each first jacket 818 are respectively provided with a third jacket 820 and a second jacket 819; the third jacket 820, the first jacket 818, and the second jacket 819 They are all made of flexible rubber material. When the front ends of the two transmission covers 814 are deflected inward and closed, the third jacket 820, the first jacket 818, and the second jacket 819 form a full circle and cover the outer wall of the core 111 for clamping it and forming a glue injection cavity; the fine adjustment frame is connected to a support frame 8111, and two racks 811 arranged on the support frame 8111, and teeth 812 arranged on the arc-shaped outer walls of the two transmission covers 814, and the teeth 812 are engaged with the racks 811 for transmission; and a first driving rod 5111 connected to the two first mounting blocks 813, the two first driving rods 5111 extend to the outer wall of the box seat 211 and are connected to the first hand push rod 511.
[0056] Furthermore, the fine adjustment frame includes a slide rail 711 fixed on the inner wall of the box seat 211, an end block 712 arranged at the end of the slide rail 711, and a mounting bar 713 installed in the slide rail 711 and slidable horizontally, the end block 712 is used to limit the movement of the mounting bar 713 and trigger a fine adjustment signal; a ratchet 911 is slidably installed on the upper surface of the mounting bar 713, a support frame 8111 is slidably installed on the lower surface of the mounting bar 713, and a connecting block 850 is arranged at the end of the support frame 8111, the connecting block 850 is fixed to the end of the ratchet 911, and a second spring is arranged between the connecting block 850 and the mounting bar 713; a ratchet assembly is arranged on the slide rail 711, the ratchet assembly includes a connecting rod 912, a ratchet block 913 arranged on the connecting rod 912 and adapted to the ratchet 911, and an elastic pressing piece 914 arranged on the slide rail 711, and both ends of the connecting rod 912 pass through the box seat 211 and are provided with handles 915.
[0057] By setting the clamping assembly and the fine adjustment frame structure, specifically, Figure 4 , 5As shown in , 6 and 7, the two symmetrical clamping assemblies gradually approach and clamp the plug 111 through their own deflection, and the front end of the plug 111 passes through the entry slot 213 and is placed between the two open and closed transmission cover bodies 814 and extends a distance. At this time, the first hand push rod 511 is pushed to drive the two first mounting blocks 813 to move in the direction close to the plane mirror 1215 inside the slide groove 220. Preferably, damping is provided between the teeth 812 and the mounting strip 713, and between the mounting strip 713 and the slide rail 711. When the first mounting block 813 begins to be pushed, the rack 811 remains stationary due to the damping setting. Under the meshing action of the rack 811 and the teeth 812, the two transmission covers When the front end of the body 814 is deflected inward and closed, since the third jacket 820, the first jacket 818, and the second jacket 819 are all made of flexible rubber materials, and the two transmission cover bodies 814 at the upper and lower parts are symmetrically distributed up and down, the third jacket 820, the first jacket 818, and the second jacket 819 finally form a full circle and cover the outer wall of the plug 111 for clamping and forming a glue injection cavity.

At the same time, this wrapped clamping method makes the alignment process of the plug 111 more accurate, and effectively reduces the deformation and bending of the plug 111 during the advancement process.
[0058] By further setting the fine-tuning frame structure, such as Figure 7 , 8 As shown, when the two transmission covers 814 are combined and pressed against each other, the force of pushing the first mounting block 813 will further drive the transmission cover 814, the rack 811, and the mounting bar 713 to move forward as a whole. When the mounting bar 713 contacts the end block 712, the force of the first mounting block 813 moving forward will further drive the support frame 8111 to move relative to the slide rail 711. Fig.11 As shown, under the action of the further arranged ratchet assembly, the support frame 8111 drives the ratchet bar 911 to move to a position close to the slide rail 711 and compresses the second spring between the connecting block 850 and the mounting bar 713. Under the joint action of the ratchet block 913, the elastic pressure sheet 914 and the ratchet bar 911, the insert 111 where the transmission cover 814 is located can be fed unidirectionally and step by step. Through this precise unidirectional feeding method, rapid alignment can be achieved, reducing the difficulty of alignment.

A connecting cavity 411 is arranged outside the arc-shaped contour of the transmission cover 814 corresponding to the storage capsule 817, and a pressure valve assembly is arranged between the storage capsule 817 and the connecting cavity 411; the pressure valve assembly includes a valve body 8171, and a mounting member 8175, a plug ball 8173, and a plug body 8172 which are arranged inside the valve body 8171 in sequence, the mounting member 8175 is in a cross structure, and the plug ball 8173 is connected to the mounting member 8175 through a first spring 8174. The mounting part 8175 abuts against the plug body 8172 under the action of elastic force, so as to block the passage of the valve body 8171; and a molding module is arranged on the box seat 211, so as to press toward the position of the storage bag 817, and force the pressure valve assembly to open for injecting glue into the connecting cavity 411; it also includes a plurality of reinforcing cavities 412 connected to the connecting cavity 411, and each reinforcing cavity 412 is connected to the first jacket 818, so as to inject glue into the glue injection cavity formed by the third jacket 820, the first jacket 818, the second jacket 819 and the insert 111, and the connecting cavity 411 and the first jacket 818 are made of light-transmitting materials.
[0061] Furthermore, the molding module includes two second mounting blocks 1011 slidably mounted on the rear half of the slide groove 220 and arranged opposite to each other, and a connecting frame 1013 respectively connected to the opposite surfaces of the two second mounting blocks 1011, a pressure roller 1012 is laterally connected between the two connecting frames 1013, and is used to squeeze the storage capsule 817 when it moves toward the transmission cover 814, and an ultraviolet lamp board 1014 is arranged on the connecting frame 1013, and the ultraviolet lamp board 1014 emits ultraviolet rays and irradiates vertically on the reinforcement cavity 412 and the first jacket 818 for rapid curing of the photosensitive adhesive.
[0062] In this embodiment, an efficient gluing method is provided, and a storage bag 817 is further provided under the shape of the transmission cover 814, such as Figure 8 As shown, the storage capsule 817 is provided with photosensitive glue, also known as light-curing adhesive or UV glue, which is a type of adhesive that achieves bonding under the irradiation of ultraviolet light. It has the advantages of fast curing speed, high mechanical strength, less environmental pollution, long storage period, high energy utilization rate, and low temperature curing;
[0063] Specifically, after the ferrule 111 completes the alignment step, the one-way locking of the fine adjustment frame structure position is completed mechanically under the action of the ratchet assembly, and the ferrule 111 can be pre-fixed through the covering effect of the third jacket 820, the first jacket 818, and the second jacket 819. At this time, the molding module is further pushed to move closer to the transmission cover 814, and the pressure roller 1012 gradually approaches and squeezes the storage capsule 817. Due to the pressure valve assembly set between the storage capsule 817 and the connecting cavity 411, as shown in FIG. Figure 8 , 13 As shown, when the storage capsule 817 is subjected to pressure, the glue will squeeze the plug ball 8173 to make it separate from the plug body 8172 and compress the first spring 8174. At this time, the corresponding valve body 8171 channel opens, and the glue sequentially enters the connecting cavity 411 and the reinforcing cavity 412 and is poured into the glue injection cavity formed by the third jacket 820, the first jacket 818, the second jacket 819, and the plug core 111.

In this process, the curing time is short, and the process of manual glue dispensing and gluing is omitted. At the same time, the cured connecting cavity 411 and the reinforcing cavity 412 can form a stable connection part of the inserted core 111, which can effectively reduce the adverse effects caused by later pulling and bending, and further improve its service life.
