Description

Technical Field

[0001] The utility model relates to the technical field of tempered film grinding, in particular to a mobile phone tempered film grinding machine. Background Art

[0002] Tempered glass is a kind of tempered glass that protects the mobile phone screen. It belongs to safety glass. The glass has very good wear resistance and is very hard. Its Vickers hardness reaches 622 to 701. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc. The tempered glass protective film is a higher level of safety protection for the mobile phone screen.

[0003] When processing the tempered film of a mobile phone, it is necessary to cut and trim a whole piece of tempered film and process it into the shape and size of the mobile phone. Various burrs will inevitably appear during the cutting and trimming, so the tempered film of the mobile phone needs to be polished. The existing technology needs to fix the position of the collected tempered film during polishing, and then use a polishing structure to polish and trim it. Although this polishing method is feasible, it still has obvious defects. It needs to be placed, clamped or pressed when fixing the position. After polishing, the tempered film of the mobile phone needs to be removed, which is cumbersome and not conducive to assembly line production.

[0004] Therefore, we proposed a tempered film polishing equipment to solve the problem of not being able to meet the assembly line production. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figure 1 The utility model provides a technical solution for a mobile phone tempered film grinding machine:

[0024] It comprises a grinding machine frame 1, a driving shaft 2 is installed through the lower part of the inner cavity of the grinding machine frame 1, and a conveyor belt 3 for transferring the tempered film of the mobile phone is mounted on the outer ring of the driving shaft 2;

[0025] A linkage shaft 4 is connected through the upper part of the inner cavity of the grinding machine frame 1, a belt 5 is sleeved on the outer ring of the linkage shaft 4, and a clamping mechanism is arranged on the outer surface of the belt 5;

[0026] The pressing mechanism comprises a hollow plastic tube 12, the inner cavity of the plastic tube 12 is plugged with a pressing column 6, and the end of the pressing column 6 is fixedly connected with a rubber ball 7 for pressing the tempered film of the mobile phone;

[0027] A grinding sheet 8 is mounted on the inner wall of the grinding machine frame 1 via fasteners.

[0028] Among them, the grinding sheet 8 is an elastic sheet, the bottom of the grinding sheet 8 contacts the top of the conveyor belt 3 and is located at the edge. There are two grinding sheets 8, which are located on both sides of the conveyor belt 3, and the two grinding sheets 8 are distributed in a V shape.

[0029] Among them, the top opening of the plastic tube 12 is smaller than the diameter of its inner cavity, the outer diameter of the clamping column 6 is the same as the diameter of the top opening of the plastic tube 12, and the bottom of the clamping column 6 is integrally provided with an anti-detachment sheet for preventing the clamping column from detaching from the plastic tube 12, and the diameter of the anti-detachment sheet is the same as the inner cavity diameter of the plastic tube 12.

[0030] Furthermore, a driving motor 9 for driving the driving shaft 2 to rotate is installed on the back of the grinder frame 1, and the output shaft of the driving motor 9 is docked and installed with the driving shaft 2 on the right side.

[0031] Furthermore, linkage gears 10 are mounted on the outer rings of the driving shaft 2 and the linkage shaft 4 located on the right side.

[0032] Furthermore, a compression spring 11 is sleeved on the outer ring of the plastic cylinder 12 and the compression column 6 , and the bottom of the compression spring 11 is fixed and bonded to the outer surface of the belt 5 .

[0033] In this embodiment, the cut and formed mobile phone tempered film product is directly laid flat on the upper surface of the conveyor belt 3. No external force is applied to the tempered film at the initial section, so the tempered film can move by the friction between the tempered film and the conveyor belt 3, that is, the drive motor 9 is started, and the drive motor 9 drives the drive shaft 2 to rotate through the output shaft. When the drive shaft 2 rotates, it drives the conveyor belt 3 thereon to rotate in a circular manner, and when it rotates, it can drive the tempered film to move in position;

[0034] When the conveyor belt 3 rotates, the two intermeshing linkage gears 10 rotate synchronously, and the linkage shaft 4 rotates at this time. When the linkage shaft 4 rotates, the belt 5 on it is driven to rotate cyclically, and when the belt 5 is cyclically rotated, the clamping mechanism on it is driven to rotate synchronously and cyclically;

[0035] When one end of the tempered film moves to the position below the belt 5, the pressing column 6 and the rubber ball 7 on the pressing mechanism will gradually come into contact and squeeze with the surface of the tempered film until the pressing column 6 rotates to a state perpendicular to the conveyor belt 3. At this time, the pressing spring 11 is in an extreme compression state. Under the support of the reverse force, the rubber ball 7 can press the surface of the tempered film and then move synchronously with the tempered film.

[0036] When the compressed tempered film enters between the two polishing sheets 8, the side of the tempered film begins to contact and squeeze with the polishing sheets 8. As the tempered film continues to move, the side of the tempered film can realize friction and polishing action with the polishing sheets 8 until it reaches the leftmost side and then falls for collection. Of course, the polishing detachment is performed on both sides here, and it is also necessary to rearrange and change the angle to polish the other two sides.

[0037] Although this technical solution requires two polishings, it can achieve automatic assembly line polishing. The polishing fineness depends on the replaceable polishing sheet 8, which can effectively remove the uneven edge of the tempered film or even burrs caused by cutting. The assembly line polishing operation can effectively improve the production efficiency of tempered film polishing.

[0038] The elastic and detachable polishing sheet 8 is designed, on the one hand, to adjust the polishing accuracy for different products, that is, to replace the polishing sheet 8, and at the same time, the V-shaped elastic polishing sheet 8 can also be designed for tempered films of different sizes, that is, when polishing, the side of the tempered film gradually enters the area formed by the two polishing sheets 8, and the polishing sheet 8 can be stretched open, that is, the friction between the polished film and the tempered film is gradually increased.

[0039] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
