In this embodiment, the inner side of the mounting port 412 is provided with a clamping recess 412, and the retaining ring 42 is arranged in the mounting port 412 and clamped with the clamping recess 412.

[0078] Specifically, the outer periphery of the retaining ring 42 is provided with a bending portion 422 bent in the axial direction, and the end of the bending portion 422 away from the retaining ring 42 is provided with a clamping strip 421 for clamping the clamping recess 412.

[0085] On the other hand, the inner ring mold body 32 is deformed and turned out to the outside of the outer ring mold body 31, so that the cavity 34 is completely opened, and then the annular core 21 soaked with the glue is loaded into the cavity 34. Then the second end of the inner ring mold body 32 is deformed, and then the inner ring mold body 32 is pushed into the inner ring mold body 32, and the inner ring mold body 32 is automatically combined with the outer ring mold body 31 under the elastic force of the inner ring mold body 32. Then the core column 33 is inserted into the inner ring mold body 32.

[0086] Then, the glue is injected into the cavity 34 through the glue injection hole 35, and the exhaust hole 36 is used for exhaust. The glue is subjected to vacuum bubble treatment before use. The bubble condition in the cavity 34 is observed during glue injection, and the glue injection needle tube is used to extend into the cavity 34 to extrude the bubbles.

[0087] After the glue is injected into the cavity 34, the glue mold 3 is placed into a pressurized and heated container to comprehensively exhaust and fix the glue in the cavity 34. After the glue is cured, the finished product core 43 is formed, the inner ring mold body 32 is turned out from the inside of the outer ring mold body 31 to the outside of the outer ring mold body 31, the finished product core 43 is taken out from the glue mold 3, and then the isolation sheet is torn off to expose the charging interface.

[0088] Finally, the function of the finished product core after curing is detected to determine whether it is qualified or not, burr inspection and cleaning of the finished product core 43 are performed, and the finished product core 43 is assembled into the ring body 41 from the mounting port 412 of the ring body 41, and then the stop ring 42 is fixedly installed on the mounting port 412 of the ring body 41.

[0089] Thus, the manufacturing method of the smart ring of the embodiment is completed.

[0090] The manufacturing method of the smart ring of the embodiment first fixes the raw material core into an annular core through a fixing mold, and then places the annular core into a cavity of a glue mold, and forms a finished product core with cured glue by injecting glue into the cavity. The finished product core can be conveniently disassembled from the ring, and the outer surface of the ring is not easy to be contaminated, so that the cleaning work of the ring is saved, and the production is more efficient. Meanwhile, the unqualified core is convenient to take out from the ring, and the operation is more convenient.
