Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a 2.5D glass film bonding device. Background Technology

[0002] Traditional glass is flat; no matter where you choose on the glass, it should be on the same plane as other points on the glass. The biggest difference between 2.5D glass and ordinary glass is that although the front of this glass is also flat, the edges are concave into an arc shape. The main function of 2.5D glass screen is to enhance the overall visual effect of the screen and the body, and improve the feel.

[0003] To further enhance the appearance and tactile advantages of 2.5D glass, it is necessary to bond the film to the 2.5D glass. However, the existing 2.5D bonding device must directly contact the film and press it down to the short side of the film. If it is pressed down to the front end of the film, it will not be able to press down the film, and the film will not adhere to the glass during bonding. If it is pressed down 1mm inside the short side of the film, it will cause air bubbles or indentations at the pressing position. Therefore, it is urgent to improve it. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a 2.5D glass film bonding device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A 2.5D glass film bonding device, characterized in that it comprises:

[0007] Workbench;

[0008] The glass is placed horizontally on the worktable.

[0009] The carrier film is laid horizontally on the plane of the glass away from the worktable, and a rectangular groove is opened on the plane of the carrier film on the side of the glass.

[0010] A diaphragm, which is fitted into a rectangular groove;

[0011] The drive assembly is mounted on the worktable and connected to the roller. The lowest point of the roller contacts the side of the carrier film away from the glass. The roller shaft axis is aligned with the width direction of the glass. The drive assembly can drive the roller to move along the extension direction of the carrier film while simultaneously driving the roller to rotate around its own axis.

[0012] Preferably, the depth of the rectangular groove is equal to the thickness of the diaphragm, so that the contact surface between the diaphragm and the glass is flush with the bottom surface of the supporting film.

[0013] Preferably, the edge of the carrier membrane has a spiral protrusion with a width greater than 1.5 mm.

[0014] Preferably, on the worktable surface, the glass, the diaphragm, and the carrier film are placed sequentially from bottom to top, with the short side of the glass near the roller shaft flush with the short side of the diaphragm near the roller shaft and the carrier film located directly below the roller.

[0015] Preferably, the carrier film has a thickness of 0.15 mm and consists of a 0.12 mm PET layer and a 0.03 mm release film.

[0016] Preferably, the glass is 170mm long and 70mm wide, and has chamfered edges.

[0017] Preferably, the thickness of the diaphragm is 0.12 mm.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Compared with existing technologies, this solution innovatively adds a carrier film to the outside of the diaphragm. This design effectively avoids direct contact between the roller and the diaphragm, thereby preventing the diaphragm from developing indentations due to friction with the roller during roll bonding, and also preventing air bubbles from appearing due to direct contact between the two in the initial stage of pressing. As a result, the problem of indentations or air bubbles after the diaphragm is bonded to the glass can be significantly improved, greatly enhancing the bonding quality. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-3 As shown, this embodiment provides a 2.5D glass film bonding device, including:

[0026] Workbench 1;

[0027] Glass 2 is placed horizontally on workbench 1;

[0028] The carrier film 3 is laid horizontally on the plane of the glass 2 away from the worktable 1, and a rectangular groove 31 is opened on the plane of the carrier film 3 on one side of the glass 2.

[0029] Membrane 5, which is adapted to be placed in rectangular groove 31;

[0030] The drive assembly is mounted on the worktable 1 and is connected to the roller 4. The lowest point of the roller 4 contacts the side of the carrier film 3 away from the glass 2. The roller shaft axis is consistent with the width direction of the glass 2. The drive assembly can drive the roller 4 to move along the extension direction of the carrier film 3 while driving the roller to rotate around its own axis.

[0031] Overall, glass 2 is placed flat on worktable 1 through suction nozzle, and then film 5 and carrier film 3 are placed flat on glass 2 in sequence. After placing glass 2, film 5 and carrier film 3, roller 4 is adjusted to be directly above one short side of carrier film 3 and in contact with carrier film 3. The drive component drives roller 4 to move along the extension direction of carrier film 3 and drive roller 4 to rotate around its own axis until roller 4 is directly above the other short side along the extension direction of carrier film 3. By roller 4 rolling and pressing along the top surface of carrier film 3, the bonding between glass 2 and film 5 can be achieved.

[0032] like Figures 2-3 As shown, in this embodiment, the depth of the rectangular groove 31 is equal to the thickness of the diaphragm 5, so that the contact surface between the diaphragm 5 and the glass 2 is flush with the bottom surface of the bearing film 3.

[0033] Specifically, the depth of the rectangular groove 31 is equal to the thickness of the diaphragm 5, so that the contact surface between the diaphragm 5 and the glass 2 is flush with the bottom surface of the carrier film 3. When the roller 4 is performing the roll pressing and bonding process, it can ensure that there is no step difference between the contact surface between the diaphragm 5 and the glass 2 and the bottom surface of the carrier film 3, so that the pressing plane is a complete plane, thereby improving the pressing effect between the diaphragm 5 and the glass 2 and avoiding the generation of air bubbles between the diaphragm 5 and the glass 2 during the pressing process.

[0034] like Figure 3 As shown, in this embodiment, the edge of the carrier film 3 has a spiral protrusion, and the width of the spiral protrusion is greater than 1.5 mm.

[0035] Specifically, the width of the spiral protrusion on the edge of the carrier film 3 is greater than 1.5mm. This can prevent the carrier film 3 from pressing the film 5 during the pressing process if the edge of the roller 4 is too narrow or has no edge, which would result in poor bonding. In addition, the width of the spiral protrusion should not be too large to avoid affecting the photography effect.

[0036] The specific width of the spiral protrusion is set according to the actual working conditions and is not limited here.

[0037] like Figures 1-2 As shown, in this embodiment, on the plane of the worktable 1, the glass 2, the diaphragm 5 and the carrier film 3 are placed sequentially from bottom to top. The short side of the glass 2 near the roller shaft is flush with the short side of the diaphragm 5 near the roller shaft and the carrier film 3 is located directly below the roller 4.

[0038] Specifically, in the vertical direction, glass 2, diaphragm 5, and carrier film 3 are placed sequentially from bottom to top, with carrier film 3 located directly below roller 4. Because carrier film 3 has a U-shaped protrusion on its edge, when roller 4 presses down to fit with carrier film 3, the indentation will only exist at the edge of the short side of carrier film 3. As roller 4 moves along the extension direction of carrier film 3, the fit between diaphragm 5 and glass 2 can be achieved. Through this structural setting, while ensuring that there are no indentations between diaphragm 5 and glass 2, it is also possible to avoid the generation of air bubbles between diaphragm 5 and glass 2 during the pressing process.

[0039] like Figure 1 and Figure 3 As shown, in this embodiment, the carrier film 3 has a thickness of 0.15 mm and is composed of a 0.12 mm PET layer and a 0.03 mm release film.

[0040] Specifically, the carrier film 3 is composed of a PET layer and a release film. By setting the release film, the adhesion between the carrier film 3 and the film 5 can be ensured, thus playing a role in isolation. The PET layer, due to its transparency and other advantages, facilitates the photographic effect of the film 5 during the roll lamination process.

[0041] like Figures 1-2 As shown, in this embodiment, the glass 2 has a length of 170mm and a width of 70mm, and the glass 2 has a chamfer.

[0042] Specifically, the length of glass 2 is 170mm and the width is 70mm. By setting chamfers at the corners of glass 2, collision damage can be reduced while also preventing damage to the corners of glass 2 due to excessive stress concentration during a collision.

[0043] like Figure 3 As shown, in this embodiment, the thickness of the diaphragm 5 is 0.12 mm.

[0044] Specifically, the thickness of the diaphragm 5 is 0.12mm, which facilitates the bonding between the diaphragm 5 and the glass 2.
