Abstract

The invention relates to a drilling method of a plate. The method comprises the following steps of providing the to-be-drilled plate, wherein the to-be-drilled plate is provided with a preset drillingpart, and the preset drilling part is provided with a first surface and a second surface opposite to the first surface; providing a plastic cushion block, wherein the plastic cushion block is provided with a fitting face, so that the plastic cushion block and the preset drilling part are stacked; utilizing a drilling part for drilling the to-be-drilled plate part from the first surface of the preset drilling part, so that the drilling part penetrates through the first surface, the second surface and the fitting face of the plastic cushion block in sequence to form a through hole in the presetdrilling part. The plate processed by means of the drilling method of the plate has short burrs or even has no burr, the technological requirement is met, there is no need to use dry ice to remove the burrs in the later period, the drilling working procedure of the plate can be simplified, the production efficiency is improved, and the yield is increased.

Description

technical field [0001] The invention relates to the field of plate processing, in particular to a method for opening holes in a plate and its application. Background technique [0002] In order to increase the screen-to-body ratio of mobile electronic devices such as mobile phones, earpiece holes with smaller apertures are usually used, and the earpiece part is arranged at the extreme edge of the top of the mobile phone. The traditional drilling method of directly drilling the plate with a drill will result in a long burr on the bottom edge of the through hole. It is easy to cause dry ice to be blocked in the earpiece hole, and it will also affect the yield of the product. Contents of the invention [0003] Based on this, a hole-drilling method of a panel is provided which improves the burr length of the hole-opening part and simplifies the hole-opening process. [0004] In addition, an application of the method for opening holes in the above board is also provided. [...
