Touch-screen glass white slice processing method
Technical field
The present invention relates to a kind of glass machining technique, refer more particularly to a kind of touch-screen glass processing method.
Background technology
Touch screen glass is as one of significant components of smart mobile phone, panel computer and other touch screen electronic products, the finished product price important of its production cost to above-mentioned electronic product, and the production cost that therefore reduces described touch screen glass has realistic meaning.In traditional handicraft, glass blocks after cutting is directly carried out CNC processing to be processed, in process, glass blocks scuffing rate reaches more than 80%, for solving the scuffing problem, by using sander to polish to eliminate scratch, as seen not only yields is low for this traditional approach, and contains this complicated technology of polishing, operation easier is high, so production cost is in high-end trim always.
Be the problem that solves above-mentioned scuffing rate and other related questions of initiation thereof, mainly adopting following two kinds in technique now improves one's methods: 1, with the glass blocks Double-layered printing paint or the printing ink that cut into, make the glass blocks outside surface form one deck paint or printing ink protective seam, the scratch phenomenon appears to prevent from processing in CNC processing, thereby reduce the scratch rate, improve yields, reduce production costs; 2, spray paint or printing ink on the glass blocks after the cutting by pneumatic gun, make the glass blocks outside surface form protective seam, to reach the effect of first kind of way;
Wherein, mode one: need the block-by-block Double-layered printing, the running time is long, production efficiency is low; Mode two: glass blocks may damage in painting process because holding air pressure that can't stand the pneumatic gun ejection, and is not easy to operate, reduces from another point of view yields.
Summary of the invention
The object of the present invention is to provide touch-screen glass white slice processing method, be intended to solve complicated operation, inefficiency, yields is low, production cost is high problem.
Technical scheme of the present invention is as follows:
Touch-screen glass white slice processing method, step is as follows:
Step 1, touch-screen raw material glass is cut into glass blocks by reservation shape;
Glass blocks after step 2, the described cutting of cleaning;
Step 3, the oven dry of the glass blocks after cleaning;
Step 4, the glass blocks dip-coating one deck protective paint solution after drying;
Step 5, will scribble the glass blocks oven dry of described protective paint solution, form one deck protection paint film;
Step 6, the glass blocks that forms described protection paint film is shaped processing;
Step 7, the glass blocks after shaping are done and are taken off film and process.
Beneficial effect of the present invention: before 1, glass blocks shapes processing, only have cutting, cleaning, oven dry, dip-coating and oven dry five steps, after glass blocks shapes processing, only need take off film and process, therefore whole job operation is simple, easy to operate; 2, described step 2, three, four, five and seven all can be processed by the multiple pieces of glass piece simultaneously, saves the running time, and efficient is high; 3, the ratio that the protection paint film that forms makes glass blocks be scratched in processing is processed is down to below 1%, and yields is high; 4, due to the simplification of operation, the raising of production efficiency and the lifting of yields make production cost be effectively reduced.

Embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearer, below in conjunction with accompanying drawing and a preferred embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
With reference to figure 1, described touch-screen glass white slice processing method, its concrete steps are as follows:
1) touch-screen raw material glass is cut into glass blocks by reservation shape;
2) glass blocks after the described cutting of cleaning is with chips of glass and other attachments of retaining on glass blocks after thorough removing cutting;
3) oven dry of the glass blocks after cleaning;
4) the glass blocks dip-coating one deck protective paint solution after drying;
5) surface attachment is had the glass blocks oven dry of described protective paint solution, formation one deck is attached to the protection paint film on glass blocks surface, shapes at CNC for the protection of glass blocks to avoid scratch in processing;
6) glass blocks that forms described protection paint film after step 5) is carried out CNC and shape processing;
7) glass blocks after CNC is shaped is immersed in and takes off in film; after the protection paint film on described glass blocks takes off; again glass blocks is taken out; the described protection paint film that this step is used for being attached to the glass blocks surface takes off; to take off again afterwards glass blocks after film and put into annealing furnace and carry out tempering and process, so far complete the whole operation of described touch-screen glass white sheet processing.
During concrete enforcement, described step 3) can adopt abluent to clean or adopt Ultrasonic Cleaning, and is effective, cleaning efficiency is high, can certainly adopt additive method to clean; The concrete operation method of described step 4) is: the glass blocks after the step 3) oven dry is immersed in described protective paint solution, make the above protective paint solution of glass blocks surface dip-coating, described protective paint solution can be contained in groove or in other containers, this step can once operate multiple pieces of glass piece, increases work efficiency; Drying time in described step 5) is 5~8 minutes, bake out temperature is 80~100 ℃, to take into account the ability of being heated of drying efficiency and glass blocks, need to prove, above-described drying time and bake out temperature are only a more excellent reference value, can set other more suitable time parameter or temperature parameters by concrete condition such as process conditions, vitreous material etc.
For optimizing all kinds of performance index of described protective paint; as adhesion, scratch resistant performance etc.; described protective paint solution is content by weight percentage; comprise following component: vinyl chloride-vinyl acetate resin 5~10%; polyvinyl butyral (PVB) resin 10~20%; urea formaldehyde 5~10%, organic solvent 55~75%, other adjuvants or auxiliary agent 0-5%.Wherein, the concrete preparation method of described protective paint solution is: vinyl chloride-vinyl acetate resin, polyvinyl butyral resin, urea formaldehyde are joined in organic solvent in proportion stir, add other adjuvants or auxiliary agent after stirring.
Above-described embodiment of the present invention does not consist of the restriction to protection domain of the present invention.Any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present invention.
