[0033] See also Figures 1 to 3 The embodiment of the present application proposes a dispensing pressure-maintaining fixture 100, including a fixture body 10 and a matching structure 20. The fixture body 10 is provided with a cavity 11 and an opening 12 connected to the cavity 11. The opening 12 is used for a product 200 having a component to be pressurized to pass through, so that the component to be pressurized of the product 200 enters the cavity 11. The matching structure 20 is arranged on the inner wall of the cavity 11, and the matching structure 20 is configured to match the component to be pressurized. Among them, the matching structure 20 is made of elastic material, so that the matching structure 20 can elastically press against the component to be pressurized when the component to be pressurized enters the cavity 11.
[0034] The dispensing and pressure-maintaining fixture 100 proposed in the embodiment of the present application includes a fixture body 10 and a matching structure 20, which has a simple structure and is easy to process. For products 200 with complex structures and requiring a local dispensing process, the cavity 11 and its opening 12 can be directly mounted on the component to be pressure-maintained of the product 200, which is easy to install and disassemble, and can minimize damage to the component to be pressure-maintained. The matching structure 20 is made of elastic material, which is conducive to designing a matching structure according to the specific shape of the component to be pressure-maintained, and can elastically press the component to be pressure-maintained after dispensing to perform local pressure maintenance, thereby applying uniform pressure to the component to be pressure-maintained to ensure sufficient curing of the glue, improve the dispensing quality, and improve the product yield.
[0035] See also Figure 1, in some application scenarios, the dispensing and pressure-holding fixture 100 of the present application can be applied to the dispensing and pressure-holding of the frame and its decorative parts of AR glasses. Of course, in other embodiments, the dispensing and pressure-holding fixture 100 of the present application can also be applied to other products, such as other electronic devices, medical devices, etc.
[0036] In some embodiments, the mating structure 20 and the component to be pressure-held have a preset interference amount, and the preset interference amount is 0.1 mm - 0.5 mm. Thus, through the setting of the above preset interference amount, it can be ensured that there is sufficient pressure between the mating structure 20 and the component to be pressure-held after dispensing, ensuring that the glue can be evenly distributed and fill the gap between the mating structure 20 and the component to be pressure-held, thereby improving the bonding effect, avoiding problems such as bubbles and voids from affecting the bonding quality, ensuring the full curing of the glue, improving the dispensing quality, and improving the product yield.
[0037] In some embodiments, in order to improve the bonding effect, the preset interference amount can be limited to 0.3 mm. Of course, the preset interference amount between the mating structure 20 and the component to be pressure-held can also be set to 0.1 mm, 0.2 mm, 0.4 mm, 0.5 mm, etc.
[0038] In some embodiments, the mating structure 20 is made of rubber or silicone. Thus, the mating structure 20 can be made of rubber or silicone to enable the mating structure 20 to elastically press against the component to be pressure-held. Among them, rubber has excellent elasticity, is easy to process and form, and can be bonded to a variety of materials, facilitating the manufacture of various complex structures to cooperate with the component to be pressure-held. Silicone has good elasticity and softness, and can also adapt to various shape and size requirements to cooperate with the component to be pressure-held.
[0039] Of course, in other embodiments, the mating structure 20 can also be made of other elastic materials, which can be formed by processing one elastic material or multiple elastic materials.
[0040] Please refer to Figures 2 to 7 , in some embodiments, the mating structure 20 includes a first protrusion 21, and the first protrusion 21 is used to be adapted to the first groove of the component to be pressure-held. Thus, when a groove is provided on the outer wall of the component to be pressure-held, the mating structure 20 can be provided with the first protrusion 21, so that it can cooperate with the first groove, enabling the mating structure 20 to fit against the component to be pressure-held and maintain elastic pressing. At this time, the first protrusion 21 and the first groove also have the above preset interference amount.
[0041] In some embodiments, the matching structure 20 includes a second groove 22, and the second groove 22 is used to match the second protrusion of the component to be pressurized. Therefore, when the outer wall of the component to be pressurized is provided with a protrusion, the matching structure 20 can be provided with a second groove 22, so that the second protrusion can be matched, so that the matching structure 20 can fit the component to be pressurized and maintain elastic pressure. At this time, the second protrusion and the second groove 22 also have the above-mentioned preset interference amount.
[0042] In some embodiments, the matching structure 20 further includes a first plane structure 23, and the first plane structure 23 is used to match the second plane structure of the component to be pressurized. Therefore, for the plane structure of the outer wall of the component to be pressurized, the matching structure 20 can be provided with the first plane structure 23, so that it can match the second plane structure, so that the matching structure 20 can fit the component to be pressurized and maintain elastic pressure. At this time, the first plane structure 23 and the second plane structure also have the above-mentioned preset interference amount.
[0043] It can be understood that the first planar structure 23 and the second planar structure can be inclined planes with an inclined angle, or can be planes parallel to the horizontal plane.
[0044] In some embodiments, the matching structure 20 further includes a first curved surface structure 24, and the first curved surface structure 24 is used to match the second curved surface structure of the component to be pressurized. Therefore, the curved surface structure of the outer wall of the component to be pressurized can be a concave curved surface or a convex curved surface, and the matching structure 20 can be provided with the first curved surface structure 24, so that it can match the second curved surface structure, so that the matching structure 20 can fit the component to be pressurized and maintain elastic pressure. At this time, the first curved surface structure 24 and the second curved surface structure also have the above-mentioned preset interference amount.
[0045] In some embodiments, the fixture body 10 has a first side surface 13 and a second side surface 14 opposite to the first side surface 13, and the opening 12 includes a first opening 121 opened on the first side surface 13 and a second opening 122 opened on the second side surface 14. The first opening 121 and the second opening 122 are both connected to the cavity 11, and the first opening 121 and the second opening 122 are used for the product 200 to pass through, so that the fixture body 10 is sleeved on the part to be pressurized of the product 200. Therefore, through the setting of the first opening 121 and the second opening 122, it is convenient to sleeve the fixture body 10 on the product 200, and it is convenient to perform glue dispensing and pressurization on the local part to be pressurized, and it is easy to install and disassemble, and it can avoid damage to the part to be pressurized as much as possible.
[0046] In some embodiments, the sizes and shapes of the first opening 121 and the second opening 122 may be different and may be configured according to the specific structure of the product 200 .
[0047] In some embodiments, the fixture body 10 is made of an elastic material. Thus, the fixture body 10 can also be made of an elastic material, which is conducive to the integral molding of the fixture body 10 and the mating structure 20, facilitating processing and reducing processing costs.
[0048] Of course, in other embodiments, the fixture body 10 can also be made of other materials, such as metal or plastic.
[0049] In some embodiments, the fixture body 10 and the mating structure 20 are integrally formed. Thus, it is conducive to the processing of the fixture body 10 and the mating mechanism, reducing processing costs.
[0050] Of course, in other embodiments, the fixture body 10 can also be separately formed from the mating structure 20 and then assembled into one body.
[0051] In some embodiments, the fixture body 10 includes a first fixture 10a and a second fixture 10b. Both the first fixture 10a and the second fixture 10b are provided with cavities 11, openings 12, and a mating structure 20 provided on the inner wall of the cavity 11; wherein, the mating structure 20 provided on the first fixture 10a is mirror-symmetrical with the mating structure 20 provided on the second fixture 10b.
[0052] Please refer to Figure 3 and Figure 6 , in some embodiments, the outer wall of the first fixture 10a is provided with a first identifier 15, and the outer wall of the second fixture 10b is provided with a second identifier 16. The first identifier 15 and the second identifier 16 are used to distinguish the first fixture 10a from the second fixture 10b. Thus, by setting the first identifier 15 and the second identifier 16, it is convenient to distinguish the first fixture 10a from the second fixture 10b and avoid confusion.
[0053] In some embodiments, the first identifier 15 can be L or other indicatable identifiers, and the second identifier 16 can be R or other indicatable identifiers.
[0054] In some usage scenarios, when the dispensing and pressure-holding fixture 100 of the present application is applied to the dispensing and pressure-holding of the frame of an AR glasses, since the frame has two temple arms, two fixture bodies 10 can be used simultaneously to respectively perform pressure-holding on the parts to be pressure-held of the two temple arms. At this time, the first fixture 10a and the second fixture 10b can be distinguished by the first identifier 15 and the second identifier 16, so as to facilitate the accurate placement of the two fixture bodies 10 and avoid confusion.
[0055] In some embodiments, the fixture body 10 can be a square, circular, oval, or irregular-shaped structure, etc., which is not limited herein.
[0056] In summary, the dispensing and pressure-holding fixture 100 proposed in the embodiments of the present application can be applied to the local dispensing of complex products 200, and the matching structure 20 formed of an elastic material can better adapt to the irregular shape of the parts to be pressure-held of the product 200, so as to provide more uniform and precise pressure control, improve the dispensing quality, and improve the product yield.
[0057] Without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.
[0058] As described above, the above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto.
