Example 1

Please refer to fig. 1, which is a schematic diagram illustrating a structure of a polishing tool 1 for cover glass according to an embodiment of the present utility model; taking the polishing jig 1 of the cover glass as an example, fig. 1 and fig. 2 are shown. The concrete steps are as follows: the convex polishing jig 1 of the cover plate glass has 6 surfaces, 5 surfaces except the upper surface are smooth planes,

the protruding tool 1 of throwing of apron glass is cubic, includes: the support groove 6 and the jig side wall 7 which jointly enclose the convex polishing jig, in this embodiment, the jig side wall 7 includes a first side wall, a second side wall, a third side wall, a fourth side wall and a fifth side wall, the support groove 6 and the first side wall are upper and lower side walls of the convex polishing jig, the second side wall and the third side wall are front and rear side walls of the convex polishing jig, and the fourth side wall and the fifth side wall are left and right side walls of the convex polishing jig. In some embodiments, the jig side 7 includes planar first, second, third, fourth, and fifth side panels that are spheres. The support groove 6 is used for supporting cover plate glass, the support groove 6 comprises more than two profiling clamping grooves 5 which are placed in parallel, each profiling clamping groove 5 is used for placing one piece of cover plate glass, the upper surface of each profiling clamping groove 5 is a curved surface, the warping degree of the upper surface is consistent with that of the cover plate glass, and the cover plate glass is enabled to be attached to the profiling clamping grooves 5 after being placed on the profiling clamping grooves. The utility model adopts one fixture to process more than two pieces of glass on the profiling clamping groove, and achieves the aim of improving the processing efficiency by increasing the polishing quantity of a single machine. Namely, one processing station on the polishing machine correspondingly uses one fixture to process 1pcs of glass at a time, one processing station is changed into one fixture correspondingly, and the fixture is additionally provided with a glass profiling clamping groove 5, so that the number of single processing is increased. The polishing device further comprises damping cloth, the damping cloth is padded on the profiling clamping groove, the depth D of the profiling clamping groove 5 from the polishing surface=the thickness d1+n of the cover plate glass×the thickness D2 of the damping cloth, and n is the number of layers of the damping cloth padded. The damping cloth can be filled up in the middle of the cover plate glass and the jig, so that the friction force can be increased to avoid glass sliding when the cover plate glass is lifted to enable the upper edges of the cover plate glass and the polishing jig to be flush. The number of the damping cloths can be gradually reduced along with the use abrasion condition of the jig, so that the service life of the jig is prolonged. The cover glass is placed in front of the profiling clamping groove 5, and then a damping cloth is padded. Considering that too thick a pad of damping cloth may affect the adsorption of cover glass, 2 to 3 layers of damping cloth may be preferred. The existence of damping cloth, except that the upper edge that the cover glass made cover glass and tool to flush of bed hedgehopping, increase frictional force avoids glass to slide, can also prolong the life of tool through reducing damping cloth quantity. Particularly, when cover plate glass polishes, the brush dish also can wear the upper surface of tool, and the tool upper surface is less than cover plate glass, can influence cover plate glass's upper edge polishing effect. Therefore, when the upper surface of the jig is worn to a certain extent, one layer of damping cloth can be removed, and the height of the cover plate glass is reduced, so that the jig is flushed with the glass again, the service life of the jig is prolonged, and the cost of the jig is reduced. In some embodiments, in order to place the cover glass on the convex polishing jig 1 without dropping, the air extraction groove 3 is arranged on the profiling clamping groove 5 of the jig, the air extraction groove 3 is provided with an air extraction hole 2, the air extraction hole 2 penetrates through the air extraction groove 3 and the jig side wall 7, and in some embodiments, the air extraction hole 2 penetrates vertically through the upper surface and the lower surface.

The air suction pump is turned on, air in the air suction groove 3 with limited air after the cover plate glass is placed can be pumped out through the air suction hole 2, vacuum is formed, and the cover plate glass is fixed on the polishing jig 1 by using pressure difference. The air suction hole 2 and the air suction groove 3 are arranged in each profiling clamping groove 5.

In some embodiments, the bleed slot 3 is a king bleed slot; the periphery of the profiling clamping groove 5 is provided with silica gel strip grooves, and the distance between the silica gel strip grooves and the edges of the profiling clamping groove 5 is 2-8 mm. Preferably, the silica gel strip groove is 5mm away from the edge of the profiling clamping groove 5. Still include the silica gel strip, the silica gel strip glues the size thickness of silica gel strip in the silica gel strip groove and is: when the polishing agent is attached between the silica gel strip groove and the cover plate glass, the cover plate glass is 0.1mm-0.4mm higher than the polishing surface. In this embodiment, the size of the silica gel strip is 9×10mm (thickness×width), so the size of the silica gel strip groove is 8.7×10mm. The highest point of the silica gel strip after installation is higher than the upper surface of the convex polishing jig 1, and the height is about 0.3mm. When polishing, when the brush is about to brush the cover glass, the raised silica gel strip can protect the upper line edge of the cover glass and prevent the upper line edge from being polished into a 2.5D product. I.e. the elevation prevents the edges from being rounded off, directly at right angles. Other adhesive tapes can also be used for the silica gel strips.
