Description

Technical Field

[0001] This application relates to the field of smart ring technology, and more particularly to a potting device for smart rings. Background Technology

[0002] As a type of smart wearable device, smart rings are mainly used for health monitoring, gesture control, and identity recognition.

[0003] The hardware in a smart ring includes various sensors, such as optical heart rate sensors, body temperature sensors, touch sensors, and accelerometers. Some of these sensors, like the optical heart rate sensor, are located on the inner surface of the smart ring. In some cases, an adhesive coating process is applied to the inner surface of the smart ring. The cured adhesive has good optical transmittance and abrasion resistance, thus protecting these sensors while still allowing them to function.

[0004] In related technologies, the glue coating process involves creating two holes in a mold: one for glue inlet and the other for glue outlet. Glue is then applied to the inner surface of the smart ring via injection. However, during the glue solidification process, a small amount of glue solidifies in the inlet and outlet holes, resulting in glue inlets on the product surface. This excess glue needs to be cut and the surface trimmed, leading to low overall production efficiency. Utility Model Content

[0005] This application aims to at least address one of the technical problems existing in the background art. Therefore, one objective of this application is to provide a glue-filling device for smart rings, thereby improving the production efficiency and quality of the glue-filling process for smart rings to a certain extent.

[0006] This application provides an adhesive filling device for a smart ring, comprising a silicone mold and an adhesive filling needle. The silicone mold has an annular groove adapted to the smart ring. The annular groove includes a first inner wall and a second inner wall disposed opposite to each other. The first inner wall is arranged opposite to the inner surface of the smart ring, forming a gap between them. Along the axis of the annular groove, the height of the first inner wall relative to the bottom of the groove is greater than or equal to the height of the smart ring, and the height of the second inner wall relative to the bottom of the groove is less than the height of the smart ring. The adhesive filling needle is used to fill the gap with adhesive.

[0007] In some embodiments, the silicone mold is further provided with an adhesive guide groove for discharging adhesive that overflows from the annular groove.

[0008] In some embodiments, the adhesive guide groove is located outside the annular groove relative to the center of the annular groove.

[0009] In some embodiments, the adhesive guide groove extends along the extension direction of the annular groove.

[0010] In some embodiments, the silicone mold is further provided with an observation hole, the inner surface of which is disposed opposite to the first inner wall, and the portion between the inner surface of the observation hole and the first inner wall is configured as a transparent body.

[0011] In some embodiments, the observation hole extends through the silicone mold.

[0012] In some embodiments, the silicone mold further has an edge that is connected to the first inner wall and extends along the first inner wall toward the second inner wall, the edge being used to contact and connect with the end of the smart ring away from the bottom of the groove.

[0013] In some embodiments, the potting apparatus for the smart ring further includes a pressing mold that mates with the silicone mold, the smart ring being disposed between the silicone mold and the pressing mold.

[0014] In some embodiments, the Shore hardness of the silicone mold is in the range of 40 to 50.

[0015] In some embodiments, the glue-applying device for a smart ring further includes a drive member for driving the glue-applying needle to move along the extension direction of the annular groove.

[0016] The technical solutions of this application embodiment can achieve at least the following technical effects: By setting up a silicone mold with an annular groove and using a dispensing needle, an annular dispensing operation can be achieved for smart rings. This improves the problem of dispensing nozzles during glue solidification, allowing the glue to be molded in one step without secondary processing. This enhances the stability and consistency of the product's appearance and improves overall production efficiency, thereby reducing costs.

[0029] Combination Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the structure of a silicone mold according to some embodiments of this application; Figure 2 for Figure 1 Schematic diagram of the cross-sectional structure along the AA direction; Figure 3 This is a schematic diagram of the structure of a glue-pouring device for a smart ring according to some embodiments of this application.

[0030] This application provides a glue-filling device 100 for a smart ring, including a silicone mold 10 and a glue-filling needle 20. The silicone mold 10 has an annular groove 11 adapted to the smart ring 200. The annular groove 11 includes a first inner wall 111 and a second inner wall 112 arranged opposite to each other. The first inner wall 111 is arranged opposite to the inner surface of the smart ring 200, forming a gap K between them. Along the axis of the annular groove 11, the height of the first inner wall 111 relative to the bottom of the groove 11 is greater than or equal to the height of the smart ring 200, and the height of the second inner wall 112 relative to the bottom of the groove is less than the height of the smart ring 200. The glue-filling needle 20 is used to fill glue into the gap K.

[0031] Silicone mold 10 refers to a mold made of silicone material. Silicone mold 10 has a certain degree of hardness to reliably support the smart ring 200, while also having a certain degree of elasticity to facilitate demolding after the glue has solidified.

[0032] The annular groove 11 is a recess for supporting the smart ring 200 and allowing the adhesive to be molded into a preset shape. In the annular groove 11, the bottom supports the end of the smart ring 200. A first inner wall 111 forms a gap K between itself and the inner surface of the smart ring 200, thereby defining a space for filling the adhesive. The first inner wall 111 restricts the flow of the adhesive, allowing it to solidify within the gap K and adhere to the inner surface of the smart ring 200. The cross-sectional shape of the solidified adhesive is the same as the cross-sectional shape of the gap K. A second inner wall 112 is used to adhere to the outer surface of the smart ring 200, ensuring that the smart ring 200 is stably placed within the annular groove 11.

[0033] Wherein, the height of the first inner wall 111 relative to the bottom of the annular groove 11 is greater than or equal to the height of the smart ring 200. It can be understood that the first inner wall 111 can completely cover the inner surface of the smart ring 200, so that the solidified glue can fully cover the inner surface of the smart ring 200.

[0034] The height of the second inner wall 112 relative to the bottom of the groove is less than the height of the smart ring 200, so that at least a part of the smart ring 200 is exposed outside the annular groove 11, so that the smart ring 200 can be removed from the silicone mold 10 after the glue has solidified, thus realizing the demolding operation.

[0035] The glue-filling needle 20 is a component used to fill glue into the gap K. In some embodiments, the movement trajectory of the glue-filling needle 20 may be along the extension direction of the annular groove 11 so that the glue can be fully filled to every position of the gap K.

[0036] In some embodiments, the adhesive may be an epoxy adhesive.

[0037] By setting a silicone mold 10 with an annular groove 11 and cooperating with a dispensing needle 20, an annular dispensing operation is achieved for the smart ring 200, which improves the problem of dispensing nozzles during the glue solidification process, allowing the glue to be molded in one step without secondary processing, improving the stability and consistency of the product appearance, and increasing the overall production efficiency, thereby reducing costs.

[0038] Combination Figures 1 to 3 As shown, according to some embodiments of this application, the silicone mold 10 is further provided with an adhesive guide groove 12, which is used to guide the adhesive overflowing from the annular groove 11.

[0039] During the dispensing process of the dispensing needle 20, if the dispensing volume is too large or the dispensing rate is too fast, some glue may overflow from the gap K. In this case, the overflowing glue can flow into the guide groove 12, and the guide groove 12 will discharge the excess glue, thereby reducing the glue residue on other parts of the silicone mold 10, thus reducing the time spent on cleaning the silicone mold 10 afterward, and further improving the production efficiency of the product.

[0040] By setting up the adhesive guide groove 12, the amount of adhesive residue on other parts of the silicone mold 10 is reduced, thereby reducing the time spent cleaning the silicone mold 10 and further improving the production efficiency of the product.

[0041] Combination Figures 1 to 3 As shown, according to some embodiments of this application, the adhesive guide groove 12 is located outside the annular groove 11 relative to the center of the annular groove 11.

[0042] If the height of the first inner wall 111 is greater than the height of the second inner wall 112, then the direction of glue overflow is from the first inner wall 111 toward the second inner wall 112. The glue guide groove 12 is located outside the annular groove 11, so that the overflowing glue can flow smoothly into the glue guide groove 12.

[0043] Combination Figures 1 to 3 As shown, according to some embodiments of this application, the adhesive guide groove 12 extends along the extension direction of the annular groove 11.

[0044] The adhesive guide groove 12 extends along the extension direction of the annular groove 11. It can be understood that the adhesive guide groove 12 is also annular, so that the adhesive guide groove 12 can achieve 360-degree full coverage, so that no matter where the adhesive overflows from, it can flow smoothly into the adhesive guide groove 12.

[0045] Combination Figures 1 to 3 As shown, according to some embodiments of this application, the silicone mold 10 is further provided with an observation hole 13, the inner surface of the observation hole 13 is disposed opposite to the first inner wall 111, and the portion between the inner surface of the observation hole 13 and the first inner wall 111 is configured as a transparent body.

[0046] The observation hole 13 is located inside the annular groove 11, that is, the middle part of the silicone mold 10 is hollowed out, and the part between the inner surface of the observation hole 13 and the first inner wall 111 is configured as transparent to facilitate the inspection of whether there are air bubble defects after the glue is poured.

[0047] By setting up the observation hole 13, it is possible to inspect for bubble defects after glue dispensing.

[0048] Combination Figures 1 to 3 As shown, according to some embodiments of this application, the observation hole 13 extends through the silicone mold 10.

[0049] The observation hole 13 extends through the silicone mold 10, thus fully covering the inner surface of the smart ring 200, allowing for full observation of all parts of the adhesive, reducing blind spots and improving the reliability of defect inspection.

[0050] In some embodiments, bubble defects can be observed using a camera.

[0051] Combination Figure 2 and Figure 3 As shown, according to some embodiments of this application, the silicone mold 10 also has an edge 14, which is connected to the first inner wall 111 and extends along the first inner wall 111 toward the second inner wall 112. The edge 14 is used to contact and connect with the end of the smart ring 200 away from the bottom of the groove.

[0052] The edge 14 is in contact with the end of the smart ring 200 away from the bottom of the groove. On the one hand, the edge 14 can press the smart ring 200 into the annular groove 11. On the other hand, the edge 14 can seal the glue in the gap K to a certain extent, so that the glue can solidify more reliably according to the preset shape, thereby improving the quality of the product.

[0053] Meanwhile, based on the elasticity of the silicone mold 10, the edge 14 can deform appropriately so that the glue-filling needle 20 can be inserted between the edge 14 and the end of the smart ring 200 and fill the gap K with glue.

[0054] According to some embodiments of this application, the potting device 100 for a smart ring further includes a pressing mold that mates with the silicone mold 10, and the smart ring 200 is disposed between the silicone mold 10 and the pressing mold.

[0055] After the glue is poured, the pressing mold is pressed onto the silicone mold 10, so that the glue can be formed more reliably in one step without secondary processing, which improves product quality and production efficiency.

[0056] According to some embodiments of this application, the Shore hardness of the silicone mold 10 is in the range of 40 to 50.

[0057] In some embodiments, the Shore hardness of the silicone mold 10 can be 40, 41, 42, 43, 44, 45, 46, 47, 48, 49 or 50.

[0058] By controlling the hardness of the silicone mold 10 within a suitable range, it ensures that the first inner wall 111 can maintain sufficient stability during the glue solidification process, and also allows the glue-pouring needle 20 to extend between the edge 14 and the end of the smart ring 200 and to pour glue into the gap K.

[0059] According to some embodiments of this application, the glue-potting device 100 for a smart ring further includes a drive member for driving the glue-potting needle 20 to move along the extension direction of the annular groove 11.

[0060] In some embodiments, the drive element may be a robotic arm.

[0061] The drive unit moves the dispensing needle 20 to perform a circular dispensing operation, so that the glue can be fully filled into every part of the gap.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
