Compared with the prior art, the glass pore processing method and the cutter of the present invention can be used to effectively solve the problem that the glass substrate is subjected to the hole punching process, and the glass substrate is not supported by the strength of the glass substrate due to the strength of the glass substrate. In addition to the rupture phenomenon, the present invention can be used to improve the quality of the boring process, and can also effectively reduce the amount of debris generated during the processing and the hole.

In order to fully understand the object, features and advantages of the present invention, the present invention will be described in detail by the following specific embodiments and the accompanying drawings, which are illustrated as follows: A schematic view of a glass hole machining tool in an embodiment. In the present embodiment, a glass-hole machining tool 10 is provided for performing the hole-cutting process of a glass substrate 2, that is, performing the operations such as grinding and cutting on the glass substrate 2 by a processing method. For forming an exit hole 3, as shown in FIG. 5, preferably, the glass hole machining tool has elasticity when acting on the glass substrate 2. The glass hole machining tool 10 includes a housing 12, a processing portion 14, an elastic body 16, and an extension portion 18. The housing 12 is provided with a receiving portion 122; the processing portion 14 is provided with a diamond knife 142 protruding from the housing 12 for grinding and cutting in a direction y1 perpendicular to the glass substrate 2, and The processing portion 14 generates a corresponding axial pressure on the glass substrate 2, and the axial pressure is fed back to the processing portion 14 in the direction y2 according to the traveling direction y1 of the grinding and cutting, and the processing portion 14 faces the processing portion 14 The direction of the receiving portion 122 is retracted, wherein the diamond knife 142 can be a concave arc, a planar discharge or a single cutting edge cutter. Preferably, the diamond cutter 142 is a concave arc structure. The elastic body 16 is disposed on the accommodating portion 122 and provides a telescopic elastic force corresponding to the axial pressure, and the elastic elastic force absorbs/adjusts the axial pressure in the direction y3, wherein the elastic body 16 can be A spring or a spring piece is exemplified by a spring; the extending portion 18 is coupled to the processing portion 14 and the elastic body 16 at the receiving portion 122, and is transmitted through the extending portion 18 such that the elastic body 12 The telescopic spring force absorbs/adjusts the axial pressure.

In addition, the glass hole machining tool 10 further includes a connecting portion 20 for connecting the housing 12 and an outer rotating body 4, and the rotating body 4 is for providing the glass hole machining tool 10 to rotate. As shown in FIG. 2, the rotating body 4 can be a motor, that is, when the connecting portion 20 is locked to the rotating body 4, the glass hole machining tool 10 can be rotated according to the rotating body 4. Rotating synchronously, in general, the rotational speed of the swivel 4 can be operated at thousands or tens of thousands of revolutions per minute (rpm).

Referring to Fig. 4, there is shown a schematic diagram of the operation of the glass hole machining tool of Fig. 3. In the schematic view (a), the glass hole machining tool 10 is vertically moved toward the glass substrate 2, and the elastic force of the elastic body 12 is such that the processed portion 14 is fixed to the receiving portion through the extending portion 18. In the portion 122, the axial pressure is not yet generated, and only the elastic force generated by the elastic body 12 exists, that is, the elastic force causes the processing portion 14 to be stationary at the accommodating portion 122; The diamond blade 142 of the processing portion 14 of the glass hole machining tool 10 is ground and cut on the glass substrate 2 such that the hole 3 is formed on the glass substrate 2, and further, the glass is thin. Because the hole machining tool 10 contacts the glass substrate 2, the axial pressure is generated synchronously in the processing portion 14, and the axial pressure is greater than the elastic force generated by the elastic body 12, which makes the processing The portion 14 is retracted toward the receiving portion 122 to absorb/adjust the axial pressure; and then in the schematic view (c), when the elastic elastic force of the elastic body 12 is unable to continuously absorb/adjust the processing portion 14 When the axial pressure is applied, the glass is processed The device 10 is reset to the same state as the schematic (a), that is, the processing portion 14 does not generate the axial pressure on the glass substrate 2, and the elastic elastic force of the elastic body 12 is restored to the uncompressed state again; Next, in the schematic view (d), the grinding and cutting operations of the diagram (b) are repeated until the glass substrate 2 is penetrated at the exit hole 3 to form a state as shown in the schematic (e). Moreover, those skilled in the art should be aware that the number of debris in the outlet 3 is positively related to the axial pressure, that is, the larger axial pressure causes the hole or the edge of the hole. The 3 lots of debris. Therefore, according to the above-mentioned actuation diagrams (a)-(e), it can be further understood that the retractable glass pore processing tool of the present invention can be utilized, so that the glass substrate 2 can be effectively reduced during the hole processing. The axial pressure, in turn, reduces the amount of the out-of-hole debris generated during the processing, and at the same time improves the quality of the exit hole, and can effectively reduce the glass substrate 2 caused by the exit hole during the processing. The phenomenon of cracks on the surface.
