Description

Technical Field

[0001] This utility model belongs to the field of glue-pouring mold technology, and in particular relates to a glue-pouring fixture and its smart ring. Background Technology

[0002] With the continuous advancement and development of technology, smart wearable devices are becoming increasingly diverse. Smart rings, as an emerging product in the market, are gradually gaining consumer attention due to their advantages such as small size, portability, and discreet wearing. Currently, there are various ring structures on the market, such as the interlocking structure smart ring. This structure typically consists of a ceramic outer ring encasing a metal inner ring, with the PCB assembly fixed using a potting process. This interlocking structure ring offers good structural strength, waterproofing and dustproofing, a pleasant feel, and comfortable wearing, resulting in a positive consumer experience and satisfaction.

[0003] However, for smart rings with a ring-like structure, the limited area for glue injection makes the glue-filling process a persistent challenge in the industry. Current glue-filling processes are mainly divided into two methods: single-stage glue-filling and double-stage glue-filling. With single-stage glue-filling, after the glue is applied, several or some windows on the ring are not perfectly flat, exhibiting significant concavity, resulting in lower product quality. While double-stage glue-filling solves the concave window problem of single-stage glue-filling, it costs twice as much, leading to higher production costs.

[0004] Therefore, this utility model addresses the above-mentioned technical problems by providing a glue-pouring fixture for one-time glue-pouring molding of smart rings. This not only solves the problem of recessed windows but also eliminates the need for secondary glue-pouring, thereby reducing production costs and improving product quality. Utility Model Content

[0023] like Figure 1-7As shown, an embodiment of this utility model provides a glue-pouring fixture, which includes at least a fixture body 1, a silicone mold 2, a ring assembly 3, a support spring 4, a central shaft base 5, and a pressing rod 6. The fixture body 1 forms a receiving cavity 7; the silicone mold 2 is placed in the receiving cavity 7, and a mold cavity 8 is formed inside the silicone mold 2. An opening groove 9 is provided on the upper side of the mold cavity 8, and the opening groove 9 penetrates the top of the silicone mold 2. A glue inlet channel 10 is provided on one side of the silicone mold 2, and the glue inlet channel 10 communicates with the mold cavity 8. A mounting hole 11 is formed in the middle of the silicone mold 2; the ring assembly 3 is connected to the mold cavity 8. The ring assembly 3 is placed in the mold cavity 8 through the opening slot 9. The mold cavity 8 is filled with glue through the glue inlet channel 10, and the ring part 12 is formed by glue injection in the mold cavity 8. The support spring 4 is annular and has a notch 13. The support spring 4 is installed in the mounting hole 11. The notch 13 can be compressed or expanded. The support spring 4 supports the silicone mold 2. The central shaft base 5 has a shaft core 14. The shaft core 14 is inserted into the support spring 4 for installation. The shaft core 14 abuts against and expands the support spring 4. The pressure rod 6 is fastened to the fixture body 1 and presses the central shaft base 5. The smart ring is formed by glue injection in one step through the glue injection fixture, which can solve the problem of the concave window 23 and eliminate the need for secondary glue injection, thereby reducing production costs and improving product quality.

[0024] Specifically, in this embodiment, the fixture body 1 has a cylindrical structure, and a receiving cavity 7 is formed in the middle of the fixture body 1. The receiving cavity 7 is used to assemble other parts of the potting fixture. The receiving cavity 7 is cylindrical, and its bottom penetrates the fixture body 1. The silicone mold 2 is a semi-enclosed structure with a slotted top. The silicone mold 2 is made of soft silicone material, or it can be made of other rubber-like materials. The silicone mold 2 is used for potting the smart ring. A mold cavity 8 is provided on the annular body of the silicone mold 2. The mold cavity 8 has a circular structure to fit the shape of the smart ring. The silicone mold 2 is used to hold the ring component 3 for potting. To facilitate the installation of the ring component 3 into the mold cavity 8, an opening groove 9 is provided on the upper surface of the silicone mold 2. The opening groove 9 has a ring structure and penetrates the mold cavity 8. Since the silicone mold 2 itself has a certain elasticity, when installing the ring component 3, the opening groove 9 can be opened to place the ring component 3 into the mold cavity 8, so as to facilitate the potting operation of the ring component 3. To facilitate the entry of adhesive into the mold cavity 8, an adhesive inlet channel 10 is connected to the mold cavity 8. The adhesive inlet channel 10 is located on one side of the silicone mold 2. More specifically, the adhesive inlet channel 10 extends from one side of the upper surface of the silicone mold 2 towards the side wall of the mold cavity 8, thereby connecting the adhesive inlet channel 10 to the mold cavity 8. Adhesive can be injected into the mold cavity 8 by connecting the upper end of the adhesive inlet channel 10 through an injection needle. After the ring component 3 is injected and cured in the mold cavity 8, it forms an adhesive ring portion 12. The adhesive ring portion 12 and the ring component 3 are integrally molded to form a smart ring. The adhesive ring portion 12 serves to stabilize the ring component 3 and enables the smart ring to achieve waterproof and dustproof effects.

[0025] Furthermore, in this embodiment, a mounting hole 11 is formed in the middle of the silicone mold 2. The mounting hole 11 is used to install the support spring 4. Specifically, the support spring 4 is made of elastic steel and has a circular structure. The longitudinal height of the support spring 4 is basically the same as the height of the mounting hole 11. A notch 13 is provided on the longitudinal side wall of the support spring 4. The notch 13 can be compressed or expanded. The support spring 4 is installed in the mounting hole 11 and can abut against and support the inner wall of the silicone mold 2, thereby stabilizing the mold cavity 8. When the support spring 4 is installed, the radial force applied to the support spring 4 can compress the notch 13 so that the support spring 4 can be placed into the mounting hole 11. When the support spring 4 is released, the support spring 4 rebounds and resets under its own elastic force, and the notch 13 is expanded so that the outer side wall of the support spring 4 can abut against the inner side wall of the mounting hole 11, thereby achieving the effect of supporting the silicone mold 2 and stabilizing the structure of the mold cavity 8.

[0026] Furthermore, in this embodiment, the central shaft base 5 is made of a rigid material such as POM or POM plastic. The central shaft base 5 has a frustum-shaped structure, and a core portion 14 is formed at the front end of the central shaft base 5. The core portion 14 can be inserted into the center of the support spring 4. The pressure rod 6 is fastened to the fixture body 1 by bolts and presses the central shaft base 5. The core portion 14 abuts against the support spring 4 and expands the notch 13, so that the support spring 4 can be pressed and stabilized towards the mold cavity 8, thereby reducing the volume of the mold cavity 8. In particular, during the glue pouring process, such as Figure 4 and Figure 5 As shown, the adhesive enters the mold cavity 8 through the adhesive inlet channel 10, filling the mold cavity 8. Due to the pressure of the adhesive, the hydraulic pressure causes the mold cavity 8 to expand, that is, the inner ring surface L1 of the mold cavity 8 moves away from the inner ring surface L2 of the inner ring 20. At this time, the silicone mold 2 will squeeze the support spring 4, compressing the support spring 4. The support spring 4 will then support the silicone mold 2 to prevent the mold cavity 8 from over-expanding, thus ensuring that there is sufficient adhesive in the mold cavity 8. At the same time, the hydraulic pressure also allows the ring component 3 in the mold cavity 8 to be fully injected with adhesive. After the injection is completed, as... Figure 6 and Figure 7 As shown, the central shaft base 5 is inserted into the support spring 4 and pressed by the pressure rod 6. At this time, the shaft core 14 expands the support spring 4, and the support spring 4 squeezes the mold cavity 8, causing the mold cavity 8 to shrink. That is, the inner ring surface L1 of the mold cavity 8 coincides with the inner ring surface L2 of the inner ring 20. The pressure of the glue in the mold cavity 8 is further increased, ensuring a better glue injection effect for the ring component 3. At the same time, the support spring 4 squeezes the inner wall of the silicone mold 2 to squeeze out excess glue and prevent the glue from staying on the inner ring surface of the ring component 3, thereby achieving the purpose of glue breakage and avoiding the formation of excess glue rings on the inner ring surface of the ring component 3.

[0027] Furthermore, in this embodiment, a hard plastic block 15 is disposed on the bottom side of the silicone mold 2. The hard plastic block 15 is placed in the receiving cavity 7 and is located at the bottom of the silicone mold 2. The silicone mold 2 presses the hard plastic block 15 tightly. A silicone pad 16 is disposed on the bottom side of the hard plastic block 15 and is placed in the receiving cavity 7. The silicone pad 16 is located at the bottom of the hard plastic block 15 and is pressed tightly by the hard plastic block 15. Specifically, the hard plastic block 15 is made of hard plastic. The hard plastic block 15 is placed on the bottom surface of the silicone mold 2 to support the silicone mold 2. After the pressing rod 6 is installed, the silicone mold 2 presses the hard plastic block 15 tightly. The silicone pad 16 is a soft plastic pad. The silicone pad 16 is placed at the bottom of the hard plastic block 15 and is pressed tightly by the hard plastic block 15. The silicone pad 16 provides a certain buffer for the hard plastic block 15 to facilitate the pressing rod 6 to press the silicone mold 2 tightly.

[0028] Furthermore, in this embodiment, a soft rubber block 17 is disposed on the upper side of the central shaft base 5. The soft rubber block 17 is placed in the receiving cavity 7 and is located on the upper part of the central shaft base 5. The pressing rod 6 presses the soft rubber block 17. A metal block 18 is disposed on the upper side of the soft rubber block 17. The metal block 18 is placed in the receiving cavity 7 and is located on the upper part of the soft rubber block 17. The pressing rod 6 presses the metal block 18. Specifically, the soft rubber block 17 is made of soft plastic. The soft rubber block 17 is placed on top of the central shaft base 5. After the pressing rod 6 is installed, the soft rubber block 17 can provide a balanced pressing force to the central shaft base 5. The metal block 18 is made of hard metal material. The metal block 18 is placed on top of the soft rubber block 17. After the pressing rod 6 is installed, the pressure of the pressing rod 6 can be evenly distributed on the soft rubber block 17 through the metal block 18.

[0029] Further, in this embodiment, the ring assembly 3 includes an outer ring 19, an inner ring 20, and a PCB assembly 21. After the ring assembly 3 is potted and cured, it forms a ring body 22. The ring body 22 includes the ring assembly 3 and a glue ring portion 12. The glue ring portion 12 encapsulates the PCB assembly 21 and bonds the inner ring 20 and the outer ring 19. Specifically, the ring assembly 3 is potted and cured to form the ring body 22, which is the formed smart ring. The glue ring portion 12 of the ring body 22 is formed by potting. The glue ring portion 12 encapsulates the PCB assembly 21 and bonds the inner ring 20 and the outer ring 19. The window 23 is usually located inside the inner ring 20. The window 23 generally includes a wireless charging window 23, a sensing detection window 23, and an LED window 23, etc. After potting, the window 23 will be filled by the cured glue. When assembling the ring assembly 3, the PCB assembly 21 is first placed on the inner ring 20, and then the outer ring 19 is placed on top to form the ring assembly 3. Before potting, the ring assembly 3 is placed in the mold cavity 8 through the opening slot 9, and then potting is performed through the glue inlet channel 10. After the glue is injected, the central shaft base 5 is inserted into the support spring 4, and finally the pressure rod 6 is installed to press the central shaft base 5, and then it is left to cure. After curing, the glue will solidify into a glue ring 12 on the ring assembly 3. The glue ring 12 encapsulates the PCB assembly 21 and bonds the inner ring 20 and the outer ring 19, thereby obtaining a smart ring product with excellent waterproof and dustproof effects. It should be noted that the potting fixture in this embodiment can obtain the finished smart ring in only one potting operation, without the problem of the recessed window 23, thus greatly improving the product yield and reducing costs.

[0030] Furthermore, in this embodiment, in order to facilitate the quick installation and disassembly of the molding rod 6, a latch 24 is provided at one end of the molding rod 6. The latch 24 is adapted to be fastened to the fixture body 1 with screws, and the latch 24 facilitates the release of the molding rod 6 from the central shaft base 5.

[0031] Furthermore, embodiments of this utility model also provide a smart ring manufactured using the aforementioned glue-filling fixture. Specifically, the steps for manufacturing a smart ring using the aforementioned glue-filling fixture for glue-filling operations are as follows: The first step is to assemble the ring component 3, then insert the ring component 3 into the mold cavity 8 through the opening slot 9, and insert the support spring 4 into the mounting hole 11, thereby obtaining the ring component 3 and the silicone mold 2 assembly. The second step is to first place the silicone pad 16 and the hard plastic block 15 into the receiving cavity 7 of the fixture body 1, then place the ring component 3 and the component formed by the silicone mold 2 into the receiving cavity 7, and finally inject the glue into the mold cavity 8 through the glue injection channel 10. The third step, after the glue injection is completed, first press the central shaft base 5 into the support spring 4, then place the soft rubber block 17 and the metal block 18 on top of the central shaft base 5, tighten the molding rod 6 onto the fixture body 1 and press the metal block 18, and finally place the entire fixture into a temperature chamber for heating and pressure curing. It should be noted that after installing the central shaft base 5, the entire assembly can be placed in a vacuum or negative pressure environment to facilitate the glue filling the space between the inner ring 20 and the outer ring 19 of the ring assembly 3. If necessary, additional glue can be applied to the silicone mold 2.

[0032] The above-mentioned potting fixture can mold a smart ring in one step through the above steps. It can not only meet the waterproof and dustproof requirements of the smart ring, but also solve the problem of the recessed window 23. Moreover, it can reduce production costs, improve product quality, and increase product yield without the need for secondary potting.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
