Description

Technical Field

[0001] This application relates to the field of tooling fixtures, and in particular to a screen dispensing auxiliary fixture. Background Technology

[0002] In the current 3C (computer, communication, and consumer electronics) industry, the assembly technology of the screen assembly and mid-frame is crucial for improving product aesthetics, user experience, and overall performance. In traditional processes, to ensure a tight connection between the screen and mid-frame and to achieve necessary sealing, waterproofing, and dustproofing, a layer of sealant is pre-applied to the mid-frame. The screen assembly is then precisely aligned and bonded, and pressure is applied for curing to enhance the stability and sealing of the connection. However, a significant drawback of this method is that the pre-installed sealant rings not only increase assembly complexity but also inevitably occupy approximately 0.5mm of valuable space at the screen edge, limiting further narrowing of the product bezel and thus affecting the key design metric of screen-to-body ratio.

[0003] To overcome the above-mentioned defects, this application studies a screen dispensing auxiliary fixture, which helps to accurately apply a ring of adhesive of a specific shape and size directly to the edge of the screen assembly, thereby obtaining a narrower bezel and achieving a higher screen-to-body ratio. Utility Model Content

[0004] In order to achieve a narrower bezel and a higher screen-to-body ratio, this application provides a screen dispensing auxiliary fixture.

[0005] This application provides a screen dispensing auxiliary fixture, which adopts the following technical solution:

[0006] A screen dispensing auxiliary fixture includes a base, a cover plate, and an adhesive layer. When the adhesive layer is provided on one side of the cover plate, an adhesive groove is formed along the outer periphery of the adhesive layer; or, when both the cover plate and the base are provided with the adhesive layer, and the base and the cover plate are engaged, an adhesive groove is formed between the adhesive layer of the base and the adhesive layer of the cover plate.

[0007] By adopting the above technical solution, the screen assembly to be glued is placed on the base, and the cover plate is placed on the screen assembly. At this time, glue is applied to the glue groove. Since the shape and size of the glue groove have been precisely set, the accuracy and consistency of glue application can be ensured. This helps to accurately apply a circle of glue of a specific shape and size directly to the edge of the screen assembly, thereby obtaining a narrower bezel and achieving a higher screen ratio.

[0008] Optionally, a positioning element is provided on the periphery of the base, and when the cover plate is engaged with the base, the positioning element abuts against the periphery of the cover plate.

[0009] By adopting the above technical solution, the positioning component can be used to position the screen assembly and the cover plate, making it convenient to position the screen assembly and the cover plate.

[0010] Optionally, at least two positioning elements are provided at intervals along the periphery of the base.

[0011] Optionally, when the cover plate mates with the base, the positioning part corresponding to the adhesive groove is provided with a clearance groove.

[0012] Optionally, the base is provided with a vacuum groove, and the vacuum groove is connected to a vacuum interface.

[0013] By adopting the above technical solution, when the screen assembly is placed on the base, the vacuum equipment evacuates the vacuum tank through the vacuum interface, so that the screen assembly can be placed more stably on the base for adhesive dispensing, and the adhesive dispensing position of the screen assembly can be more precise.

[0014] Optionally, the vacuum tank includes a first vacuum tank and a second vacuum tank. The first vacuum tank is formed around the base, and the second vacuum tank extends from the vacuum interface to the first vacuum tank in the width and length directions of the base.

[0015] Optionally, both the base and the cover plate are provided with corresponding magnet holes, and magnets are provided in the magnet holes. The magnetic poles of the magnets in the base and the cover plate are opposite to each other.

[0016] By adopting the above technical solution, the screen assembly can be clamped and fixed by the mutual attraction of magnets.

[0017] Optionally, a plurality of magnet holes are provided around the base and the cover plate, and the magnets are arranged in a one-to-one correspondence with the magnet holes.

[0018] Optionally, the base is provided with mounting holes.

[0019] By adopting the above technical solution, the base is installed on the foundation of equipment, etc., through the mounting holes.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. Place the screen assembly to be glued on the base, cover the screen assembly with the cover plate, and then apply glue to the glue tray. Since the shape and size of the glue tray have been precisely set, the accuracy and consistency of glue application can be ensured. This helps to accurately apply a ring of glue of a specific shape and size directly to the edge of the screen assembly, thereby obtaining a narrower bezel and achieving a higher screen ratio.

[0022] 2. The positioning components can be used to position the screen assembly and the cover plate, making it easier to position the screen assembly and the cover plate.

[0023] 3. When the screen assembly is placed on the base, the vacuum equipment evacuates the vacuum tank through the vacuum interface, so that the screen assembly can be placed more stably on the base for adhesive dispensing, and the dispensing position of the screen assembly can be more precise.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] Example 1:

[0032] Embodiment 1 of this application discloses a screen dispensing auxiliary fixture. (Refer to...) Figure 1 The screen dispensing auxiliary fixture includes a base 1, a cover plate 2, and an adhesive layer 3. When the adhesive layer 3 is provided on one side of the cover plate 2, in this embodiment, the adhesive layer 3 is provided in a rectangular frame structure and is provided on the bottom wall of the cover plate 2. The adhesive layer 3 has an adhesive groove 4 along its outer periphery, and the adhesive groove 4 is provided in an "L" shape.

[0033] Reference Figure 2In this embodiment, the width and length of the base 1 and the cover plate 2 are equal. When the screen assembly is placed on the base 1 and the cover plate 2 is fitted with the base 1, the groove of the glue groove 4 faces the outer side between the base 1 and the cover plate 2. The position of the screen assembly that needs glue is located at the glue groove 4. It is only necessary to verticalize the jig and rotate the glue dispensing tool around the glue groove 4 to dispense glue on all four sides. This can help to accurately apply a circle of glue of a specific shape and size directly to the edge of the screen assembly, thereby obtaining a narrower bezel and achieving a higher screen ratio.

[0034] In some embodiments, a positioning member 5 is provided on the periphery of the base 1. In this embodiment, the positioning member 5 has a rod-shaped structure, and the surface facing the base 1 is an arc surface. It is fixed to the base 1 by screw connection. When the cover plate 2 is engaged with the base 1, the positioning member 5 abuts against the periphery of the cover plate 2, so that the placement position of the cover plate 2 can be positioned, and the position of the screen assembly can also be positioned, so that the glue dispensing position is accurate.

[0035] In some embodiments, at least two positioning elements 5 are spaced apart along the periphery of the base 1. In this embodiment, three positioning elements 5 are provided; specifically, one is provided along the width direction and two are spaced apart along the length direction, so as to enable better positioning.

[0036] In some instances, when the cover plate 2 mates with the base 1, the corresponding positioning part 5 of the glue groove 4 is provided with a clearance groove 6, which is used to allow for glue dispensing, making it easier to dispense glue.

[0037] Reference Figure 3 In some embodiments, a vacuum groove 7 is provided on the base 1, and the vacuum groove 7 is connected to a vacuum interface 8. An external vacuuming device is connected through the vacuum interface 8. When the screen assembly is placed on the base 1, the screen assembly is attracted to the base 1 by vacuuming, so that the screen assembly can be stably fixed.

[0038] In some embodiments, the vacuum groove 7 includes a first vacuum groove 71 and a second vacuum groove 72. The first vacuum groove 71 is formed around the base 1, and the second vacuum groove 72 extends from the vacuum interface 8 to the first vacuum groove 71 in the width and length direction of the base 1, so that the screen assembly can be evenly adsorbed, so that the screen assembly can be more stably fixed.

[0039] In some embodiments, the base 1 and the cover plate 2 are provided with corresponding magnet holes 9, that is, the position and number are corresponding. In this example, the magnet holes 9 are cylindrical and magnets 10 are provided in the magnet holes 9. The magnets 10 in opposite directions of the base 1 and the cover plate 2 have opposite magnetic poles. Therefore, the screen assembly can be clamped between the base 1 and the cover plate 2 by the mutual attraction of the magnets 10 between the base 1 and the cover plate 2. In other embodiments, the base 1 and the cover plate 2 can also be clamped by other clamping devices to fix the screen assembly.

[0040] In some embodiments, a plurality of magnetic holes 9 are provided around the base 1 and the cover plate 2. In this embodiment, the magnetic holes 9 on the base 1 are located on the outer periphery of the vacuum groove 7, and the magnetic holes 9 on the cover plate 2 correspond one-to-one with the magnetic holes 9 on the base 1. Magnets 10 are also provided one-to-one with the magnetic holes 9. This allows for uniform clamping and fixing along the periphery of the screen assembly, and the center of the screen assembly is fixed by vacuum adsorption, thus enabling more stable fixing of the screen assembly.

[0041] In some embodiments, the base 1 is provided with mounting holes 12. In this embodiment, four mounting holes 12 are provided between the first vacuum groove 71 and the second vacuum groove 72, and the base 1 can be stably fixed to other equipment through the mounting holes 12.

[0042] The implementation principle of the screen dispensing auxiliary fixture in Embodiment 1 of this application is as follows: the screen assembly to be dispensed is placed on the base 1, and the cover plate 2 is placed on the screen assembly. At this time, the glue is dispensed by aligning with the glue groove 4. The fixture is placed vertically at 90° and rotated to dispense glue on the four sides of the screen assembly. Since the shape and size of the glue groove 4 have been precisely set, the accuracy and consistency of the dispensing can be ensured. This can help to accurately apply a circle of glue of a specific shape and size directly to the edge of the screen assembly, thereby obtaining a narrower bezel and achieving a higher screen ratio.

[0043] Example 2:

[0044] Embodiment 1 of this application discloses a screen dispensing auxiliary fixture. (Refer to...) Figure 4 The difference between this embodiment and embodiment one is that: when both the base 1 and the cover plate 2 are provided with an adhesive layer 3, the length and width of the cover plate 2 in this embodiment are smaller than the length and width of the base 1, and the base 1 is provided with an installation groove 11. The adhesive layer 3 of the cover plate 2 is provided on the bottom surface, and the adhesive layer 3 of the base 1 is provided on the side wall of the installation groove 11, that is, the inner wall surface of the base 1 corresponding to the installation groove 11.

[0045] Reference Figure 5When the base 1 and the cover plate 2 are engaged, the adhesive layer 3 of the cover plate 2 is located in the mounting groove 11. The adhesive layer 3 of the base 1 and the adhesive layer 3 of the cover plate 2 form an adhesive groove 4. That is, the inner circumference of the adhesive layer 3 of the base 1 and the outer circumference of the adhesive layer 3 of the cover plate 2 form an adhesive groove 4. The screen assembly is placed in the base 1 with the groove opening of the adhesive groove 4 facing upward, and adhesive is applied along the four sides using an adhesive application tool.

[0046] Refer again Figure 4 In this embodiment, the magnet hole 9 is partially opened between the vacuum grooves 7 of the base 1, and the remaining part is opened along the width direction of the base 1. The position of the magnet hole 9 of the cover plate 2 is also opened accordingly.

[0047] This embodiment is identical to Embodiment 1 except for the differences between the two.

[0048] The implementation principle of the screen dispensing auxiliary fixture in Embodiment 2 of this application is as follows: the screen assembly to be dispensed is placed on the base 1, and the cover plate 2 is placed on the screen assembly. At this time, the glue is dispensed into the glue groove 4. The fixture is placed horizontally to dispense glue on all four sides. Since the shape and size of the glue groove 4 have been precisely set, the accuracy and consistency of the dispensing can be ensured. This can help to accurately apply a circle of glue of a specific shape and size directly to the edge of the screen assembly, thereby obtaining a narrower bezel and achieving a higher screen ratio.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
