[0042] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific embodiments of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solutions claimed in the present invention.

[0043] Example 1: As Figures 1 to 6 As shown, this embodiment provides a manufacturing process for a smart ring, including the following steps:

[0044] S1 involves soldering the flexible PCBA and the rechargeable battery together, and performing functional and / or optical tests on the electronic components of the flexible PCBA to identify and eliminate problematic flexible PCBAs. This ensures the stability of the electronic component functions and optical performance of the flexible PCBA.

[0045] S2, the flexible PCBA and rechargeable battery are installed inside a metal ring shell, and the ring shell is placed in the ring fixing fixture 1 so that the flexible PCBA and rechargeable battery are tightly attached to the inner wall of the ring shell. The adhesion state of the flexible PCBA and rechargeable battery is detected by a thickness detection instrument so that the arrangement of the flexible PCBA and rechargeable battery is optimized to the most uniform adhesion state.

[0046] S3. Rotate the flexible PCBA to bring the infrared LED of the flexible PCBA to the preset position, and then use UV glue to bond and fix the flexible PCBA and the ring shell to obtain the smart ring semi-finished product. Here, bringing the infrared LED to the preset position means: rotating the flexible PCBA to align the position of the infrared LED of the flexible PCBA with the concave position on the ring shell, thereby ensuring the correct installation of the flexible PCBA and improving the installation accuracy of the product.

[0047] S4. The PCBA cleaning equipment is used to clean the fixed smart ring semi-finished product, and an electron microscope is used to check whether there is dirt on the optical components of the smart ring semi-finished product.

[0048] If yes, continue using PCBA cleaning equipment to clean the smart ring semi-finished product until the optical components of the smart ring semi-finished product present a clean mirror surface; if not, proceed to step S5.

[0049] The above steps can further improve the quality of the finished product and prevent dirt from damaging or affecting the flexible PCBA.

[0050] S5, install the smart ring semi-finished product into the flexible container fixture, and adjust the position of the smart ring semi-finished product by rotation. Then, use a vacuum cleaner to vacuum and clean the flexible container fixture and / or smart ring semi-finished product to remove any dust or other foreign objects that may be present inside the flexible container fixture and / or smart ring semi-finished product.

[0051] The above steps can further improve the quality of the finished product and prevent dust or other foreign objects from damaging or affecting the finished smart ring.

[0052] S6. A precise amount of UV glue is injected into a flexible container fixture with a pre-installed smart ring semi-finished product using a precision micro-injection device until the UV glue fills the entire inner cavity of the flexible container fixture to obtain a smart ring module. This ensures the sealing of the finished smart ring and improves the quality of the finished smart ring.

[0053] S7. Place the smart ring module in a vacuum environment with a preset vacuum level and let it stand for 2-8 hours. The environment for the smart ring module to stand is effectively guaranteed, which ensures that the UV glue can be fully solidified and improves the quality of the resulting smart ring.

[0054] S8: Place the smart ring module inside a UV light box and irradiate the smart ring module with UV lights inside the UV light box.

[0055] Specifically: The smart ring module is placed on a movable and flip-up jig.

[0056] The fixture is placed inside a UV lamp box with a specific wavelength and constant temperature. The constant temperature environment inside the UV lamp box can be adjusted and controlled.

[0057] Adjust the position and / or angle of the fixture table;

[0058] The UV lamps inside the UV light box irradiate the smart ring module at different angles for 2-8 hours, ensuring that the smart ring module is fully irradiated and inspected, thereby improving the quality of the resulting smart ring product.

[0059] S9 is used to grind and polish the finished smart ring, improving the texture and aesthetics of the finished smart ring surface.

[0060] By using the production process provided in this embodiment to produce smart rings, production efficiency can be improved to a certain extent, and the quality of finished products can be stabilized.

[0061] In this embodiment, as Figures 2 to 6As shown, the annular fixing fixture 1 includes a first fixing block 11, a second fixing block 12, and a third fixing block 13. A limiting block 110 is provided on the first fixing block 11. An arc-shaped surface 111 adapted to the outer surface of the ring housing 2 is formed on the inner side of the limiting block 110. A protrusion 1110 adapted to the concave point 200 of the ring housing 2 is provided on the arc-shaped surface 111. The second fixing block 12 and the third fixing block 13 are located inside the ring housing 2 and on the first fixing block 11. The center line of the second fixing block 12 coincides with the center line of the first fixing block 11. The ring housing 2 is constrained between the second fixing block 12 and the arc-shaped surface 111. The ring housing 2 can be positioned by the cooperation of the protrusion 1110 of the arc surface 111 and the concave point 200 of the ring housing 2; and the center line of the second fixing block 12 coincides with the center line of the first fixing block 11, so that the center line of the flexible PCBA and the center line of the concave point 200 of the ring housing 2 are on the same straight line, ensuring the installation accuracy of the components and improving the quality of the resulting smart ring product.

[0062] Furthermore, a limiting groove 120 for accommodating the charging post 3 of the smart ring is provided on the second fixing block 12. There are two limiting grooves 120, which correspond to the position of the charging post 3 of the smart ring. This allows for the positioning of the charging post 3 of the flexible PCBA, ensuring the installation accuracy of the components.

[0063] The distance between the third fixing block 13 and the ring shell 2 is equivalent to the thickness of the rechargeable battery 4, thereby securing the rechargeable battery 4 tightly within the inner cavity of the ring shell 2 of the smart ring.

[0064] In this embodiment, a molding cavity 500 is provided on the flexible container fixture 5, and a positioning point 501 matching the recess 200 on the outer surface of the ring housing 2 is provided within the molding cavity 500. Furthermore, the flexible container fixture is made of a flexible material.

[0065] The flexible container fixture 5 provided in this embodiment is a container made of a special flexible material (the special material includes Teflon, silicone, etc.). A special flexible material container with a finished smart ring is made. Utilizing its properties, the semi-finished smart ring 6 can be placed inside the flexible container fixture 5 when it deforms. Then, when the flexible container fixture 5 returns to its original shape, the semi-finished smart ring 6 is tightly fixed within the molding cavity 500 of the flexible container fixture 5. Positioning points 501 are provided within the molding cavity 500, which can cooperate with the recesses 200 on the outer surface of the ring shell 2 to achieve positioning. At this time, glue can be poured in. The glue will flow and fill the entire molding cavity 500 of the flexible container fixture 5. Since the flexible container fixture 5 forms the cavity of the finished smart ring, the finished smart ring is formed after the glue cures.

[0066] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
