Abstract

The invention relates to a screen tapping method and a grinding head. After a screen is fixed, the grinding head continuously moves downwards in the axial direction at a certain feeding speed while rotating, a through hole grinding surface of a through hole section at the bottom end of the grinding head grinds the screen, and a through hole is formed in the surface of the screen; when the grindinghead continues to move downwards until a reaming section makes contact with the edge of the through hole, the edge of the through hole is ground through a reaming grinding face surrounding the circumferential direction of the reaming section of the grinding head to increase the hole diameter; and when the grinding head is driven to continuously move downwards until a fine trimming section of thegrinding head makes contact with the edge of the hole, the through hole is ground by using a fine trimming surface surrounding the circumferential direction of a fine trimming section of the grindinghead to smoothen the edge. The grinding head is designed to be in a three-section type, and sequentially comprises the through hole section, the reaming section and the fine trimming section from theend of the grinding head in the length direction, which sequentially penetrate through the screen in the tapping process. By means of the screen tapping method, the tapping yield can reach 99.65%, andfew waste materials are generated; and in the through hole stage, the grinding head continuously applies very small longitudinal pressure to the screen, the borne reaction impact is very small, and the probability that the grinding head is damaged is very low.

Description

technical field [0001] The invention relates to the field of electronic equipment processing, in particular to a screen opening method and a grinding head. Background technique [0002] With the development of mobile communication technology, full screens have been increasingly applied to smart electronic devices. Following Liu Haiping and water drop screens, in order to further increase the screen-to-body ratio of mobile phones, through-hole screens have become the next mainstream design solution, and opening holes on the screen is the key process of through-hole screens. [0003] At present, holes on optical screens can generally be cut with a laser cutter or directly drilled with a CNC drilling machine. However, the heat generated when cutting with a laser cutter is high, which is easy to cause damage to the screen and related components around it, and The investment cost of laser cutting equipment is high, the operation process is complicated, and the labor cost is high...
