Description

TECHNICAL FIELD

[0001] The present application relates to the field of glass cover plate production, and in particular to a glass cover plate polishing device. BACKGROUND

[0002] Glass is an amorphous inorganic non-metallic material, which is generally made of various inorganic minerals such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc. as the main raw material, and a small amount of auxiliary raw materials are added. The glass protection screen is also called glass cover plate, which is mainly used for touch display units to protect touch sensors and display panels and other precision electronic components.

[0003] Glass polishing is a method to increase the smoothness of the glass surface. For example, patent application No. CN202020494874.8 discloses a polishing mechanism of a 3D mobile phone glass cover plate polishing machine. The polishing mechanism drives the lifting driving element to drive the connecting block to slide up and down in the fixed frame, and the connecting block further drives the polishing assembly to lift, thereby adjusting the height of the polishing assembly. By setting the lower sealing plate and the connecting block, when the connecting block descends to abut against the lower sealing plate, it cannot continue to move downward, thereby preventing the polishing assembly from continuing to move downward. At this time, the polishing assembly is at the lowest point and can polish the glass cover plate. However, this type of polishing device can only polish the flat surface of the glass, and cannot effectively polish the curved surface of the glass.

[0004] The present application is proposed to overcome the shortcomings of the prior art. SUMMARY

[0015] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0016] Example 1:

[0017] like Figure 1 As shown, this embodiment discloses a glass cover polishing device, including a base plate 1, a rotary motor 2 fixed on the base plate 1, a fixed seat 3 fixed at the output end of the rotary motor 2, a top plate 4 fixed above the base plate 1, a lead screw 6 and a slide rod 5 also provided on the top plate 4, the lead screw 6 is driven to rotate by a positioning motor 7, a slide plate 8 is also provided above the top plate 4, a positioning tube 9 and a sliding sleeve 10 are fixed at the bottom of the slide plate 8, the lead screw 6 passes through the positioning tube 9 and is threadedly connected to the positioning tube 9, and the slide rod 5 passes through the sliding sleeve 10 and is threadedly connected to the positioning tube 9. The sliding sleeve 10 is slidably connected, and screws 11 are provided on both sides of the slide plate 8. The screws 11 are driven to rotate by the corresponding lifting motors 12. A fixing plate 13 is provided below each screw 11, and a threaded tube 14 is fixed on each fixing plate 13. The screws 11 are threadedly connected to the corresponding threaded tubes 14. A rotating shaft 17 is also provided below the top plate 4. The rotating shaft 17 passes through the two fixing plates 13 and is rotatably connected to the fixing plates 13. A grinding roller 18 is fixed on the rotating shaft 17, and the rotating shaft 17 is driven to rotate by a grinding motor 19. The glass cover plate to be polished is placed on the fixed base 3. The positioning motor 7 drives the lead screw 6 to rotate. Since the lead screw 6 is threadedly connected to the positioning tube 9 on the slide plate 8, when the lead screw 6 rotates, the slide plate 8 moves in the direction of the lead screw 6. The polishing motor 19 drives the polishing roller 18 to rotate. When the slide plate 8 moves, the polishing roller 18 moves on the surface of the glass cover plate to polish the surface of the glass cover plate. When the polishing roller 18 reaches the edge of the curved surface of the glass cover plate, the lifting motor 12 drives the screw 11 to rotate. Since the screw 11 is threadedly connected to the threaded tube 14, when the screw 11 rotates, the threaded tube 14 moves in the direction of the screw 11, and the polishing roller 18 moves in the direction of the screw 11. When the polishing roller 18 moves, the height of the polishing roller 18 is adjusted to polish the curved surface of the glass cover plate. This device can polish curved glass cover plates.
