Glass polishing brush and polishing method and polishing device

Abstract

The invention discloses a glass polishing brush. Bristles are densely distributed on the surface of a brush body, and adopt PBT wires; the brush body is a rotatable structure with axis; the bristles are uniformly distributed on the outer circular surface of the turntable type rotatable brush body in a bundle manner; each bundle of bristles is formed by weaving the bristles after folding and binding one bundle of bristles; and the bristle weaving angle is zero, that is, the bristle bundles are wholly perpendicular to a polished surface during polishing. A glass polishing method comprises the following steps: when the surface of a workpiece is polished by using the disc-shaped brush, cerium oxide polishing liquid is filled in the bristles; and the polishing liquid is bonded on the bristles in a water drop form. A glass polishing device comprises the circular turntable-structured brush and a clamping base positioned rightly below the brush, wherein the base can move front, back, left and right, and has a deflection function to adapt to the surface of 3D structural glass with a bent curved surface. The brush is obvious in effect and high in polishing efficiency; the method saves materials, and reduces the use level of the polishing liquid; and the device is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of glass polishing, in particular to a glass polishing brush, a polishing method and a polishing device. Background technique [0002] In the glass lens processing industry, the lens is usually polished with a brush, especially for the hole, and the light side wall is preferably polished with a fine brush. The existing brush materials use pig hair or other animal hair, and the source of animal hair is limited, and glass polishing requires the length of the brush hair, usually more than 5cm can be used, so the source is scarce and the price is extremely high , restricting the use of large quantities in this industry, affecting cost and processing efficiency. The most serious defect at present is that the brushes made of animal hair have a very short service life, with an average of about 3 hours, which is equivalent to a brush that can only polish 30pcs of product side walls and R angles in the most ideal state, which...

Problems solved by technology

The existing brush materials use pig hair or other animal hair, and the source of animal hair is limited, and glass polishing requires the length of the brush hair, usually more than 5cm can be used, so the source is scarce and the price is extremely high , restricting the use of large quantities in this industry, affecting cost and processing efficiency

The most serious defect at present is that the brushes made of animal hair have a very short service life, with an average of about 3 hours, which is equivalent to a brush that can only polish 30pcs of product side walls and R angles in the most ideal state, which causes the brush to be damaged. Great waste and low work efficiency, Chinese patent CN200680036280.5 discloses a kind of polishing brush and polishing method applied by Japan HOYA Co., Ltd., the patent has mentioned that its bristle material is nylon (PET) fiber, and its polishing method mainly It uses a cylindrical brush with bristles to polish the workpiece, and at the same time provides polishing fluid to the polished surface of the workpiece

For the two schemes of using animal hair and nylon bristles as bristle materials, the inventors of the present application did a comparative experiment. When animal hair and nylon bristles were used as the bristle materials, the polishing liquid could not be adsorbed on the bristles, and all the polishing liquid remained on the workpiece. On the surface, the bristles and the polishing liquid are separated, which is prone to defects such as poor polishing effect, uneven surface roughness, and low polishing efficiency.
