Abstract

The invention discloses a device and a method for processing a glass sheet material. The device comprises a feeding mechanism, a film pasting mechanism, a processing route planning mechanism, a sandblast mechanism, a demolding mechanism and a drying mechanism, wherein the feeding mechanism realizes automatic feeding of a glass sheet material needing to be processed; the film pasting mechanism automatically pastes a glue film layer on at least one side of the glass sheet material; the processing route planning mechanism removes glue film parties which are located on the glass sheet material and do not need protection so that cutting processing routes are obtained; the sandblast mechanism carries out sand blast etching of the surface of the glass sheet material by high-speed micro-powder particles according to the cutting processing routes so that the glass sheet material is cut according to the cutting processing routes; the demolding mechanism carries out washing and glue film removal processes on the cut glass sheet material; and the drying mechanism dries the washed glass sheet material so that the glass sheet material forms a single mother plate or is divided into multiple sub-plates.

Description

technical field [0001] The invention relates to a device and method for processing and cutting strengthened glass plates, and impacting and eroding the surface of glass plates with high-speed micro-powder particles to cut glass plates, in particular to a processing device and method for glass plates. Background technique [0002] Due to the strong growth of the application market for tempered glass sheets such as glass touch panels, glass sheets with stronger surface strength, more scratch resistance, and more impact resistance have been continuously developed. However, the processing of harder and brittle glass sheet materials is inherently difficult. It is not easy, but these highly strengthened glass plates make the cutting process more difficult. For example, for small-sized glass touch panels such as mobile phones, the existing processing method is to use CNC engraving machine tools to cut and process. The fine superhard material plated on the drill bit of the CNC engra...

Problems solved by technology

[0003] However, there are still some shortcomings and problems in the above-mentioned existing method of cutting glass plates with CNC engraving machine tools. Among them, the existing CNC engraving machine tools are all used for cutting and processing panel glass with drill needles inlaid with superhard material particles, and the cost is 20,000~ Grinding at a high speed of 60,000 R.P.M. The feed speed of the tool is about 50mm per minute to 800mm per minute. Therefore, in the process of high-speed grinding and cutting, high-speed grinding instantly causes local high temperature and high-frequency impact , it has been proved that the strength of the strengthened glass will be greatly reduced, and the sharpness of the abrasive on the grinding tool will reduce the cutting ability due to wear or abrasive particles falling off. At this time, if the same feed rate is maintained, it will definitely cause In the case of broken knives or broken glass sheets, it is difficult to monitor and measure the wear and tear of the knives during the processing, and the user can only judge by experience when using it, so that the cutting quality cannot be stabilized and guaranteed.

[0004] In addition, the above-mentioned existing CNC engraving machine grinding and cutting glass plate method is mainly to use a high-hardness drill bit to grind the glass plate at high speed, which will generate instantaneous high temperature locally, which often causes the glass plate to produce brittle strain and fragmentation or damage. Its strength is reduced, especially in deep-strengthened glass sheets. Therefore, in order to ensure the quality of each processed glass sheet, the above-mentioned existing glass sheet processing device and method must be cut and formed one by one. Afterwards, the process of strengthening, coating, and printing the glass panels one by one cannot be processed in the ideal mode of using the entire mother board as a whole for overall strengthening, coating, printing, and then cutting into small pieces. Multiple processes are carried out for each plate, making the overall process cumbersome and troublesome, resulting in high manufacturing costs such as panel glass, which is much higher than the cost and man-hours of the ideal process of processing the entire motherboard

[0005] Moreover, if the mother board that has been strengthened, coated, and printed is cut, punched and grooved, etc., processed into sub-pieces, the above-mentioned existing CNC engraving machine grinding, processing and cutting method is not only slow, but also has a high fragmentation rate. Once a fragment occurs, it often involves damage to multiple pieces at one time. At the same time, the most serious thing is to destroy the strength of the strengthened glass, causing the material to lose part of its original strength and characteristics.

[0006] In addition, in terms of related previous patent technical documents, Taiwan Patent Publication No. I237623 "Thin Plate Glass Drilling Method" invention patent and No. 507778 "Four-axis synchronous optical glass cutting machine structure" utility model patent case, It is revealed that the above-mentioned typical existing CNC engraving machine grinding, processing and cutting device and method still have the problems and shortcomings of broken knives, broken glass plates and unfavorable overall glass plate processing.

[0007] In addition, China Taiwan Patent Publication No. I324544 "Laser Segmentation Device and Method for Glass Workpiece" and No. 458837 "Using Ultra-cooling Airflow to Laser Cut Glass" Invention Patent, respectively disclose two kinds of laser beam Although the device and method technology for cutting and processing glass plates by cutting tools can avoid the problems and shortcomings of drill bit tool breaking in the above-mentioned existing CNC engraving machine grinding and cutting devices and methods, but the power of the laser beam It is not easy to control, and the absorption of laser beam power by each part of the glass plate cannot be guaranteed to be uniform, so that after the glass plate is cut, the fracture edge often deviates from the original cutting path. If it deviates to the inside, it may cause the entire glass plate to fail to be repaired. Another more serious disadvantage is that this method mainly uses instantaneous heat and cold alternately to split the materials on both sides of the cutting line due to internal stress. This method is only suitable for straight-line cutting lobes, just like the traditional diamond tool cutting The method of line slivers cannot be implemented for small radius arcs (such as radius less than 5mm) or drilling and grooves, which greatly limits the processing function and application range
