Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent ring, in particular to an intelligent ring containing electrodes, a glue filling jig and a packaging process thereof. BACKGROUND

[0002] The intelligent ring for health detection has become a new star in the wearable electronic device market due to its convenience, non-sensing and continuous measurement. In order to meet the use requirements of users in various scenarios, the packaging process of the intelligent ring needs to meet high waterproof sealing and also needs to have excellent wearing comfort.

[0003] There are two common packaging processes for intelligent rings,

[0004] A: The first is the assembly of molded inner and outer shells, that is, electronic components are placed in the shell cavity, an O-ring is installed for sealing, and then the inner shell is installed in the reserved groove and fixed by screws or buckles to complete the packaging.

[0005] B: The second way is the glue filling process, such as used in patent US10,893,833B2, that is, electronic components are first placed in the molded shell cavity, and the thickness of the electronic components must be less than the thickness of the shell cavity, and then a plastic filling material is used to fill the ring cavity until the electronic components are completely covered and sealed.

[0006] A: Molded inner and outer shell assembly. The ring produced using this process has good rigidity, but the complex structure increases the processing cost and the fixed way through screws or buckles cannot meet the high waterproof sealing; on the other hand, it also increases the weight and thickness of the ring, reducing the wearing comfort, which is contrary to the original design of the intelligent ring for comfortable, continuous and non-sensing health detection.

[0007] B: Traditional glue filling process. The intelligent ring produced using this process has a simple structure and high waterproofness, but it requires the thickness of the electronic components to be less than the thickness of the cavity, which makes it difficult to assemble electronic components containing electrodes, such as magnetic charging metal electrodes or health detection electrodes that need to be in contact with the human body (such as electrocardio or skin detection electrodes). The above electrodes need to be stably connected with the electronic circuit board, and part of the electrode needs to be exposed on the outer surface of the ring, and the traditional glue filling process cannot meet the requirements.
