Abstract
The invention discloses a groove cutting method for a mobile phone screen glass cover plate, which comprises the following steps: cutting the part to be cut of the glass cover plate according to a preset first cutting track, and reserving a margin at the tail end of the cutting track, wherein the margin is larger than the corner-falling size; cutting the allowance according to a preset second cutting track to form a groove. The invention can improve the yield of products and save the cost.
Description
Technical Field
The invention relates to the technical field of mobile phone screen glass cover plate processing, in particular to a groove cutting method for a mobile phone screen glass cover plate.
Background
A mobile phone screen glass cover plate belongs to electronic screen protection equipment. At present, a part of the upper parts of the outer surfaces of the mobile phone screen glass cover plates are respectively provided with a groove and a camera hole. As shown in fig. 1-3, in the process of feeding and processing the groove by using the conventional scheme, when the processing of the groove approaches to the ending position, the groove notch of the mobile phone screen glass cover plate is affected by the impact of cutting fluid and gravity to generate corner defect, so that the reject ratio of the processed mobile phone screen glass cover plate is increased, and the production cost is increased.
Disclosure of Invention
In order to solve the technical problems in the background art, the invention provides a groove cutting method for a mobile phone screen glass cover plate.
The invention provides a groove cutting method for a mobile phone screen glass cover plate, which comprises the following steps:
cutting the part to be cut of the glass cover plate according to a preset first cutting track, and reserving a margin at the tail end of the cutting track, wherein the margin is larger than the corner-falling size;
cutting the allowance according to a preset second cutting track to form a groove.
Preferably, the remainder is triangular.
Preferably, the margin is similar to the corner drop.
Preferably, the recess is rectangular or trapezoidal.
Preferably, before cutting the portion to be cut of the glass cover plate according to the preset first cutting track, the method further includes:
obtaining a glass cover plate; the glass cover plate is provided with a first cutting track and a second cutting track, so that the grooves can be cut conveniently.
According to the groove cutting method for the mobile phone screen glass cover plate, the original method for cutting the glass cover plate once to form the groove is changed into the method for cutting the glass cover plate twice to form the groove, and a margin is reserved at the tail end of a cutting track when the first cutting is carried out; therefore, even if the corner is dropped due to the impact of the cutting fluid and the influence of gravity, the corner is also generated in a reserved allowance area, and the appearance of the notch position of the groove is not influenced; and cutting the reserved allowance in the second cutting process to meet the requirement of the dimensional appearance. The invention can improve the yield of products and save the cost.

Detailed Description
It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other. The invention will be described in detail below with reference to the drawings in connection with embodiments.
Referring to fig. 2 to 4, the method for cutting the groove of the mobile phone screen glass cover plate provided by the invention comprises the following steps:
cutting the part to be cut of the glass cover plate according to a preset first cutting track, and reserving a margin at the tail end of the cutting track, wherein the margin is larger than the corner-falling size;
cutting the allowance according to a preset second cutting track to form a groove.
The method changes the original method of forming the groove by once cutting the glass cover plate into twice cutting to form the groove, and the margin is reserved at the tail end of the cutting track when the first cutting is carried out, so that cutting waste 1 is generated; therefore, even if the corner is dropped due to the impact of the cutting fluid and the influence of gravity, the corner is also generated in a reserved allowance area, and the appearance of the notch position of the groove is not influenced; cutting is performed on the reserved allowance in the second cutting process, and cutting scraps 2 are generated so as to meet the requirement of the dimensional appearance. The invention can improve the yield of products and save the cost.
It should be noted that the first cutting trace and the second cutting trace are arranged according to the outline of each cut portion.
Since the drop angle is generally triangular, in order that the drop angle that may occur at the time of the first cutting does not affect the appearance of the notch position of the groove, the margin is triangular in this embodiment.
In a further embodiment, the margin is similar to the chamfer to match the chamfer shape, further reducing the effect of the chamfer on the appearance of the notch location of the groove that may occur when cutting for the first time.
In this embodiment, the grooves are rectangular or trapezoidal.
In this embodiment, before cutting the portion to be cut of the glass cover plate according to the preset first cutting track, the method further includes:
obtaining a glass cover plate; the glass cover plate is provided with a first cutting track and a second cutting track, so that the grooves can be cut conveniently.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
