[0040] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0041] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] As shown in Figures 1-6, a mold for packaging optical devices includes a base 1, a receiving block 2, a liquid infusion tube 3, a cover 4, a positioning post 5, a mounting plate 6, a limiting block 7, a mounting plate 6 fixing assembly, and a limiting block 7 fixing assembly. The base 1 has a processing groove 11. The receiving block 2 is detachably disposed in the processing groove 11, and it has multiple evenly distributed receiving grooves 21. Adjacent receiving grooves 21 are interconnected, and the inner wall of the receiving groove 21 is coated with a hydrophilic material. When fluid is injected into the receiving groove 21, due to the surface tension of the inner wall, the fluid will form a concave meniscus in the receiving groove 21, and the receiving groove 21... The central area is the lowest point of the meniscus; the infusion tube 3 is fixed on the side wall of the base 1, with one end extending into the processing groove 11; the positioning pins 5 are evenly fixed on the four corners of the bottom surface of the cover 4, and the base 1 has positioning holes 12 for the positioning pins 5 to be inserted; the cover 4 has through holes 42, which are corresponding to the receiving groove 21; the mounting plate 6 can be inserted into the insertion groove 41 and moved; the limiting block 7 is evenly arranged on the mounting plate 6 through the limiting block 7 fixing assembly, and it has fiber optic limiting holes 71, which allow the fiber optic cable to pass through. Therefore, during processing, the fiber optic limiting holes 71 corresponding to the fiber optic cable to be processed are first placed on the mounting plate 6. The limiting block 7 is fixed to the mounting plate 6 by the limiting block 7 fixing assembly. Then, the mounting plate 6 is inserted into the bottom of the insertion slot 41, so that the fiber limiting hole 71 is aligned with the receiving slot 21. The mounting plate 6 is then fixed to the cover 4 by the mounting plate 6 fixing assembly. Next, the optical device to be coupled is placed in the receiving slot 21. Then, the optical fiber is passed through the fiber limiting slot and through hole. After applying curing liquid to the end of the optical fiber, the end of the optical fiber is inserted into the receiving slot 21. Fluid is introduced into the processing tank 11 through the liquid infusion tube 3 and flows into the receiving slot 21. Due to the surface tension of the inner wall of the receiving slot 21, the optical device will... Floating at the lowest point of the meniscus in the receiving tank 21, the upward height of the optical device is controlled by adjusting the flow rate of the incoming fluid until it couples with the optical fiber. After overall solidification, fluid is extracted from the infusion tube 3 to lower the liquid level, thus obtaining the coupled encapsulated structure of the optical device. The mold can be adapted to optical fibers and optical devices of different sizes through the design of the detachable receiving block 2 and the limiting block 7. The cooperation between the positioning post 5 and the positioning hole 12 ensures precise alignment of the cover 4 and the base 1, avoiding coupling deviation. The infusion tube 3 is used for injecting and extracting fluid, which, combined with the meniscus formed by the hydrophilic coating inside the receiving tank 21, enables the self-floating positioning of the optical device. This structure solves the problem of poor versatility of traditional molds, significantly improves encapsulation accuracy and efficiency, and simplifies the operation process.

[0043] Specifically, the mounting plate 6 fixing assembly includes an elastic connecting rod 81, a rotating shaft 82, and a locking post 83. The elastic connecting rod 81 is curved in an arc shape, and one end is fixed to the mounting plate 6. One end of the rotating shaft 82 is rotatably connected to the elastic connecting rod 81. The locking post 83 is sleeved and fixed on the rotating shaft 82. The mounting plate 6 has a locking groove 61 that mates with the locking post 83. When the mounting plate 6 is inserted into the bottom of the insertion slot 41, the fiber optic limiting hole 71 and the through hole are aligned, and the locking post 83 and the locking groove 61 are aligned. Under the action of the elastic connecting rod 81, the locking post 83 will be inserted into the locking groove 61, thereby completing the fixing of the mounting plate 6.

[0044] Specifically, the fixing assembly of the limiting block 7 includes a mounting groove 91, a limiting protrusion 92, and a locking component. The mounting groove 91 is evenly distributed on the mounting plate 6, allowing the limiting block 7 to be inserted. The limiting protrusion 92 is fixed to the inner wall of the mounting groove 91 to support the limiting block 7. The side wall of the limiting block 7 can fit against the mounting groove 91, and the top surface of the limiting protrusion 92 can fit against the bottom surface of the limiting block 7. The locking component includes a mounting hole 93, an elastic element 94, a push rod 95, and a ball 96. The mounting hole 93 is formed on the side wall of the mounting groove 91. The elastic element 94 is a spring, one end of which is fixed inside the mounting hole 93. The push rod 95 is located inside the mounting hole 93 and can slide relative to the inner wall of the mounting hole 93, with one end connected to the end of the elastic element 94. The ball 96 is rotatably connected to the end of the push rod 95. The side wall of the limiting block 7 is provided with a locking component. When installing the limiting block 7, align the limiting block 7 with the mounting groove 73, then press down on the limiting block 7. The ball 96 will be squeezed and enter the mounting hole 93. When the bottom surface of the limiting block 7 contacts the limiting protrusion 92, the ball 96 will align with the groove, and the elastic element 94 will push the ball 96 into the groove, thus fixing the limiting block 7. When the limiting block 7 needs to be replaced, pull the mounting plate 6 outward to remove it from the insertion groove 41, then push the limiting block 7 upward from the bottom of the mounting plate 6 to push it out of the mounting groove 91. Then, insert the new limiting block 7. This design simplifies the installation steps of the limiting block 7; only pressing is needed to fix it. Disassembly is done by reversing the operation, significantly improving operational efficiency and the modularity of the mold.

[0045] As a preferred option, the bottom sides of the limiting block 7 are provided with arc-shaped curved surfaces 72. The arc-shaped curved surfaces 72 on both sides of the bottom of the limiting block 7 can reduce the contact friction with the mounting groove 91, play a guiding role during the installation process, make it easier for the limiting block 7 to slide into the correct position, and the arc-shaped curved surfaces 72 facilitate pressing the ball 96 into the mounting hole 93.

[0046] As a preferred option, the mounting plate 6 is fixedly provided with multiple anti-slip protrusions 62. The anti-slip protrusions 62 on the surface of the mounting plate 6 increase the roughness of the contact surface, thereby improving the stability of manual gripping during operation.

[0047] As a preferred embodiment, the bottom of the receiving block 2 is fixedly provided with a mounting post 22, and the bottom of the processing groove 11 is provided with a fixing hole for the mounting post 22 to be inserted. Multiple elastic protrusions 23 are fixedly provided on the outer wall of the mounting post 22, and the inner wall of the fixing hole is provided with a groove that mates with the elastic protrusions 23. The receiving block 2 is detachably connected through the insertion and engagement of the bottom mounting post 22 with the fixing hole of the base 1. The engagement of the elastic protrusions 23 with the groove provides additional locking force, ensuring that the receiving block 2 is securely installed and vibration-resistant. This design facilitates the quick replacement of the receiving block 2.

[0048] As a preferred option, the top of the receiving block 2 is provided with a pull ring 24. The pull ring 24 on the top of the receiving block 2 simplifies the extraction operation. The operator can directly apply force to the pull ring and avoid contact with the receiving groove 21.

[0049] As a preferred embodiment, the mounting plate 6 has a guide surface 63 at its end. The guide surface 63 is curved in an arc shape. The curved guide surface 63 at the end of the mounting plate 6 can reduce the frictional resistance at the entrance of the insertion slot 41, guide the mounting plate 6 to be inserted smoothly, and reduce the difficulty of alignment.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
