Description

Glass plate 3D curved surface non-contact processing system and method

The invention relates to a 3D curved surface non-contact processing system and method for glass sheets, in particular to a system and method for processing a flat glass sheet by at least one non-contact heat source cutting, processing device and fixing jig to form 3D curved glass.

According to the three-dimensional curved glass panel, it is widely used in a new generation of smart phones, tablets, electric instrument panels, display glass panels and automotive instrument panel products, providing smart phones, tablets, electric instrument panels, display glass panels and The edge surface display or touch operation function of the upper, lower, left and right directions of the automobile instrument panel product, however, the conventional method of manufacturing and processing the three-dimensional curved glass panel, whether it is first bending the glass plate by the mold Forming and then cutting with CNC machine tools or cutting the glass plate in the 2D plane with CNC machine tool and then bending the glass plate with hot stamping of the mold, or cutting the glass plate with laser in 2D plane and then bending the glass plate with mold. It is necessary to press-form the glass sheet C with an upper mold A and a lower mold B made of a graphite material as shown in the first figure, that is, it must be processed by a contact processing tool and a mold.

However, in the above-mentioned conventional three-dimensional curved glass panel, the processing technology and manner of the contact processing tool and the mold are in the process of cutting or leading the corner of the glass plate C, such as cutting with a CNC machine or grinding and polishing the corner. The contact processing will cause irregular shape chipping and micro-fracture seams or irregular burrs on the edge of the glass sheet C workpiece, except that the processing time of the glass sheet C workpiece is increased and the productivity is low (about 2 to 5 minutes). / each piece) and the quality is uneven, the glass sheet C still has to be trimmed and polished with a polishing machine. However, even if the edges and edges of the glass sheet C are smoothly trimmed by mechanical polishing, each The degree of tool wear is different, so that the size of the glass sheet C of each piece of the contact-type polishing and trimming plane is uneven, and there are dimensional errors of different sizes, which seriously affects the precision and quality of subsequent processing.

Furthermore, in the contact-type processing process of heating and bending the above-mentioned mold A and the lower mold B of the above-mentioned three-dimensional curved glass panel as shown in the first figure, it is necessary to perform high-temperature heating operation on the entire glass sheet C, that is, as a whole heating and In the process of stamping, it is necessary to use the upper mold A and the lower mold B made of graphite in the process of heating and operating at a high temperature, in addition to the dimensional error caused by the polishing process after the flat glass sheet C is cut. However, the finished product of the glass sheet C is also subjected to dimensional error, so that the gap between the molds A and B is difficult to set. For example, if the gap between the molds A and B is too small, the glass sheet C is thermally expanded and has nowhere to be. Can be accommodated, which will lead to rupture, and the gap between the molds A and B is too large, which may cause the position of the glass sheet C to shift, resulting in subsequent deviations in the perforation or drilling processing position of each piece of glass sheet C, and The oxidized and detached carbon powder and other impurities of the molds A and B of the residual glass material on the surface of the glass plate C, and the carbon powder of the graphite molds A and B will form a pothole, and the surface of the glass plate C will be Embossing more rough pit surface, after the glass sheet C is bent and demolded, a large number of additional repair steps must be performed after the surface polishing and slag cleaning and polishing polishing, in addition to the glass After the sheet C is bent and formed, the yield of the finished product is greatly reduced (the yield is about 50%), and the process cost of bending the glass sheet C is high, which is inconsistent with the economic benefits of industrial utilization.

In addition, the above-mentioned conventional glass sheet C is heated and bent by a graphite upper mold A and a lower mold B, and the graphite has a lower yield and a higher cost of subsequent surface polishing treatment, and further, the graphite The mold set A and the lower mold B mold set also have a service life limit. Each set of upper mold A and lower mold B mold set is heated after using 1000~3000 pieces of glass sheet C, and it is necessary to stop and replace a new set. The upper mold A and the lower mold B mold group can continue to operate the heating and bending process of the glass sheet C, which not only improves the bending processing cost of the entire glass sheet C, but also the heating and bending process of the conventional glass sheet C The process and the mechanism equipment are lengthy and complicated, so that the average interval between the completion of the discharge of each piece of the glass sheet C is also elongated, that is, the interval between the completion of the bending processing of each piece of the glass sheet C is about 50 to 60 seconds, to average every hour. The number of pieces that can be completed is about 60 pieces per hour, which highlights that the overall productivity is inefficient and cannot meet the requirements of industrial utilization, and on the other hand, the graphite is made. A lower die having an internal and fully cover the mold B glass sheet C, no way of measuring the temperature of the heated glass sheet C is distributed only on the outside of the graphite mold A and B to push a single point temperature measurement It is impossible to confirm the heating temperature distribution of the actual points on the glass sheet C, and of course, it is impossible to accurately monitor the heating temperature of the actual points on the glass sheet C. Therefore, in the actual hot bending process of the glass sheet C, local heating is easily caused. If the temperature is too high or too low, the glass sheet C may have surface ablation spots, cracks, or excessive internal stress, which may cause problems such as a decrease in mechanical strength of the glass sheet C, which is brittle and fragile.

In addition, in the related patent documents of the related art, such as the invention patent case of "The method for manufacturing and manufacturing a glass product and the electronic device" of the Republic of China Patent No. I460139, it is disclosed that the conventional conventional upper and lower molds are combined to heat the glass plate. The processing technology and device of the bending process, similarly, there is a difference in the yield of the contact-heated glass sheet process and the technology as shown in the first figure shown above, and the subsequent polishing and finishing of the surface of the glass sheet is required. The error of the glass sheet size, the short service life of the mold need to be replaced frequently, the process of the process and the length and complexity of the mechanism equipment make the glass sheet finished product have a long interval of discharge and the overall process cost is high, which is inconsistent with the economic benefits of industrial utilization.

In addition, as in the case of the US Patent No. 8783066 "GLASS MOLDING SYSTEM AND RELATED APPARATUS AND METHOD" and the Japanese Patent Publication No. JP5934801 "Forming Device" invention patent, further The method and technology for contacting heated curved glass sheets of the conventional large-scale and complex long process graphite material molds as shown in the first figure above are disclosed. Similarly, there is a conventional heat bending of the graphite material mold shown in the first figure. The yield of the glass sheet process and the technology is poor, the subsequent polishing and finishing of the glass sheet surface, the error of the glass sheet size, the short service life of the mold need to be replaced frequently, the process of the process and the length and complexity of the mechanism equipment make the discharge interval of the glass sheet finished product. The long time and the overall process cost are high, and the problems and shortcomings of the industrial utilization economic benefits are not met.

(102) and the non-reformable region (104) to a first temperature, and the first temperature corresponds to the first viscosity, and subsequently locally heating the reformable region (102) to a second temperature, the second temperature corresponding to At a second viscosity, wherein the second viscosity is lower than the first viscosity, forming a bend in the reformable region (102) during local heating of the reformable region (102), Forming the bending step by contacting the first push rod (402) with the non-reformable region (104) and translating the first push rod (402) along a linear path to the non-reformable region (104) Applying a thrust to form the bend in the reformable zone (102) or contacting the second pusher (502) with an edge region of the reformable zone (102a) and rotating the first along the circular path a second push rod (502) for applying a thrust to the edge region of the reformable region (102a), and forming a system and technique for contact bending in the reformable region (102a), such as the patent Figures 4a to 4d of the drawings, it is apparent that the patent premise must pass through two processing steps, and it is necessary to contact the non-reformable section (104) through the push rod (402), and The reformable zone (104) applies thrust to cause the bend in the reformable zone (102), which tends to cause the glass sheet (100) to form on the surface of the curved portion where the pusher (402) contacts after the bending is completed. Contact wear, and the subsequent processing of the surface of the glass sheet (100) by the polishing of the push rod (402) must be performed. And, whether the bending of the glass sheet (100) is perfect or not depends on the force control of the push rod (402) applying a thrust to the non-reformable region (104), such as when the force is applied, the bending will be excessive. There is a problem that the glass sheet (100) is embrittled and broken, and when the applied thrust is insufficient, the bending quality of the glass sheet (100) may be poor, and the quality of the bending force of the glass sheet (100) is not good. Qi can not be precisely controlled.

In the above-mentioned conventional or prior patents, the contact glass sheet cutting, the lead angle, the polishing, the bending process and the technique have the difference in yield, the subsequent polishing and polishing on the surface of the glass sheet, and the size of the glass sheet. The error, the short service life of the mold need to be replaced frequently, the process of the process and the length and complexity of the working hours of the mechanism equipment, the processing process, the long interval between the discharge of the glass sheet products and the overall process cost are high, and the economic benefits such as industrial utilization are not satisfied.
