The glass panel processing method can solve the technical problems of high edge breakage rate and long production downtime caused by the processing method, and achieves the purpose of reducing the edge breakage rate and the downtime of products.
Description
Technical Field

Background
In the process of processing a glass panel in a touch screen of electronic equipment, the edge shape needs to be processed, and various functional through holes, such as a microphone hole and a key hole, need to be processed, for example, HOME keys of a mobile phone and a tablet computer.
In the forming and processing process of a numerical control machine (CNC for short), after cutting, the CNC shape processing allowance is 1-2 mm, namely, after a glass substrate is processed into a glass panel, the edge of the glass substrate needs to be removed by 1-2 mm, and the rough shape trimming process needs to be removed by 0.7-1.4 mm. The traditional processing sequence is to place the glass substrate on a base, process the appearance of the glass substrate first, and then process the through hole. The base is provided with a water enclosing groove, and cooling liquid is gradually injected into the water enclosing groove after the glass substrate is fixed on the base so as to cool the glass substrate in the processing process. At present, the technological process of firstly processing the appearance and then processing the through hole is adopted because the processing size of the glass appearance is large, and the glass is easy to expand with heat and contract with cold in the processing process, so that the processing position of the through hole is easy to deviate.
The inventor finds in production practice that when the glass substrate is processed by the method, the glass appearance is processed after the glass substrate is fixed on the base, and at the moment, the glass substrate is not completely soaked by the cooling liquid, so that the appearance of the processed glass substrate is easy to have edge breakage, and the edge breakage rate is 30-50%; if the machine is stopped and the shape is processed after the cooling liquid in the base is filled, the time of about 15s needs to be waited, and the cooling liquid in the base needs to be discharged after each glass substrate is processed so as to fix the glass substrates, so that the production efficiency is seriously influenced by the operation method.

A glass panel processing method comprises the steps of fixing a glass substrate on a base of processing equipment, introducing cooling liquid into the base, processing through holes in the surface of the glass substrate, and processing the appearance of the glass substrate.
The glass panel processing method provided by the invention is characterized in that after a glass substrate is fixed on a base of processing equipment, cooling liquid is introduced into the base, through holes on the surface of the glass substrate are processed, and then the appearance of the glass substrate is processed. Compared with the traditional processing method, the processing method has the advantages that the processing sequence is adjusted, the through holes are processed firstly, the processing time of the through holes is generally 1-2 min, at the moment, the water enclosing groove of the base is filled with cooling liquid, the glass substrate is completely soaked in the cooling liquid, at the moment, the appearance processing is carried out on the glass substrate, the glass substrate can be cooled by 100%, and edge breakage caused by excessive cutting amount and insufficient cooling in the appearance processing process of the glass substrate is fully improved.

Meanwhile, due to the fact that the through holes are machined in the process of introducing the cooling liquid, the process cannot cause the problem of halt, and therefore production efficiency can be improved.
Production practices prove that the edge breakage rate of the glass panel product can be controlled within 2% by using the processing method provided by the invention. Compared with the method of stopping the machine to store the cooling liquid fully, the method can save the storage time of the cooling liquid and further improve the production efficiency.
In the present invention, the processing equipment refers to grinding equipment for processing Glass, and examples of the processing equipment include Glass500, Glass500E, and Glass500E Mini manufactured by the Ikegaku corporation. Meanwhile, the glass panel targeted by the processing method is a panel for electronic equipment, such as a glass panel of a mobile phone, a glass panel of a tablet computer and the like.
In some embodiments of the present invention, the glass panel is a touch screen panel of a mobile phone, and the through hole is a receiver hole and/or a key hole. After the glass substrate is fixed on a base of processing equipment, cooling liquid is introduced into the base, a tin hole and/or a key hole are processed, and then the appearance of the glass substrate is processed.
For example, the shape of the glass substrate is processed by processing the tin cylinder hole and the key hole of the glass panel of the mobile phone, so that the scrap rate of the broken edges of the glass panel of the mobile phone can be effectively reduced, and the production efficiency of the glass panel of the mobile phone is improved. The processing sequence of the tin cylinder hole and the key hole is not limited, the processing sequence can be interchanged, and the appearance of the glass substrate is processed after the tin cylinder hole and the key hole are completely processed.
For another example, in some embodiments of the present invention, the glass substrate is processed by machining the can hole, and then the outer shape of the glass substrate is processed, and then the key hole is processed. This processing sequence of just using both can reduce the edge breakage rate of product, improves production efficiency, can also effectively guarantee the accuracy of the earphone hole of product and key hole processing position with the earphone hole as the benchmark.
In some embodiments of the invention, the through-hole or glass substrate profile is machined using a grinding wheel bar.

The reaming process parameters comprise: the rotating speed of the grinding wheel rod is 24000 and 28000r/min, and the feeding speed of the grinding wheel rod is 35-55 mm/min. The technological parameters of the fine trimming hole chamfer include: the rotating speed of the grinding wheel rod is 24000 and 28000r/min, and the feeding speed of the grinding wheel rod is 70-130 mm/min.
Since the cooling liquid in the base is not yet filled when the through hole is machined, the machining of the through hole is performed in a state where the through hole is not protected by the cooling liquid. In the above embodiment, the grinding wheel rod is used for processing, and the specific rotating speed and feeding speed are matched, so that the change of the internal stress of the glass substrate caused by processing can be fully released in the processing process, and the glass substrate is prevented from cracking or edge breakage caused by unreasonable processing technology setting.
In some embodiments of the invention, the machining of the glass substrate profile includes rough machining and finish machining. The rough machining is to basically machine the external dimension of the glass substrate to the dimension of the finished glass panel, and at the moment, a large amount of glass needs to be cut off. And the finish machining is mainly to perform chamfering machining and arc surface machining on the edge of the glass substrate after rough machining. In some embodiments of the invention, the roughening comprises roughing the profile, and the process parameters comprise: the rotating speed of the grinding wheel rod is 22000-. The finish machining is to trim the chamfer and the arc surface of the glass substrate, and the technological parameters comprise: the rotating speed of the grinding wheel rod is 22000-.
