Background technology
At present, the same industry all adopts physical method both at home and abroad, namely uses numerical control (CNC) cutting, punching, edging and polishing, processes the glass cover-plate of capacitive touch screen.Its defective is: the processing work efficiency of the machines such as numerically-controlled machine low (CNC of two statures can only process the Cove-lens200 sheet left and right of 3.5 inches every day), facility investment and factory building area occupied are all larger, cause depreciation, maintaining expense and financial expense all very high, and then cause production cost high.Work efficiency is high to adopt hydrofluoric acid etch moulding process processing Cover l ens, facility investment and factory building area occupied little (equal production capacity only is equivalent to the former 15% and 50% left and right), but thereby the decrease production cost, enhance productivity.Adopting the key technical problem of hydrofluoric acid etch moulding process processing capacitance plate glass cover-plate is the protective layer Generating Problems of substrate glass.
Summary of the invention
The purpose of the embodiment of the present invention is to provide a kind of protective layer generation method for toughened glass cover plate etch-forming, the problem that the protective layer when being intended to solve target converted products (abbreviation substrate glass) hydrofluoric acid etch moulding generates.
The embodiment of the present invention is achieved in that a kind of protective layer generation method for toughened glass cover plate etch-forming, and this protective layer generation method comprises the following steps:
PVC film mill is cut blank mark;
The blank mark of substrate glass double faced adhesive;
Hydrofluoric acid etch;
Flushing, edging, polishing, pull out sheet and namely get the etch-forming intermediates.
Further, select a kind of PVC self-adhesive plastic film material of hydrofluoric acid resistant to prepare required protective film, be processed into the shape consistent with target product (being called for short blank mark), and it is pasted two surfaces up and down of substrate glass symmetrically; Thereby the efficient part of substrate glass is protected, and invalid target is exposed in hydrofluoric acid, makes its corrosion that is subject to hydrofluoric acid and attenuation, change is broken and even eroded fully, finally obtains the intermediates consistent with the target product shape.
Further, through simultaneous test screening repeatedly, select the PVC self-adhesive plastic film as the protective film material, utilize punch press with cutting die, the PVC processing film to be become the blank mark consistent with target product Cover lens, with pneumatic chip mounter, two identical blank marks are pasted symmetrically two surfaces up and down of substrate glass; And then place it in the hydrofluoric acid of 5 to-5 ℃ of concentration 45-70%, temperature and soaked about 60 minutes; the efficient part of substrate glass is under blank target protection; invalid target is exposed to for some time in acid solution and is corroded; take out and rinse the intermediates that namely get desired shape; again to middle product carry out edging, polishing, pull out sheet, cleaning, tempering and silk-screen overlay film, namely get at last required Cover lens.
Further; select the PVC self-adhesive plastic film as protective layer; with cutting die, PVC self-adhesive plastic film protective layer is processed into the blank mark consistent with the glass cover-plate target product with punch press; two identical blank marks are placed in symmetrically two surfaces up and down of base plate glass; use the pneumatic motor paster; the cover plate efficient part is under protective layer, and invalid target is as exposures such as four limits, circular hole and square holes.Paster glass is placed in the hydrofluoric acid of 45-70% concentration, soaks 60min, exposure portion is eroded fully, takes out paster glass, washs 1min with clear water.
further, employing thickness is 0.25mm, width is the PVC film of 236mm, process the blank mark of 200PCS with punch press and cutting die, with the pneumatic motor paster, two identical blank marks are pasted on symmetrically two surfaces up and down of 100PCS substrate glass, post in blank target substrate glass (being called for short paster glass) the PVC mould bases of packing into above-mentioned again, mould bases being placed in again and filling concentration is 75%, temperature is in the acid tank of hydrofluoric acid solution of-5 ℃, take out again mould bases after soaking 45min from acid tank, wash the 1min left and right with flushing with clean water, again paster glass is pulled down from mould bases, carry out again edging, polishing, plectrum, clean, tempering, silk-screen and overlay film, namely get required toughened glass cover plate.
Positively effect of the present invention: select the PVC self-adhesive plastic film as protective layer and be processed into the blank mark consistent with glass cover-plate target product shape; the method that is used for the hydrofluoric acid etch moulding; energy is disposable editing objective product (Cove-lens) in batch simultaneously; the processing work efficiency is more much higher than CNC moulding; therefore can significantly save facility investment and factory building area occupied; thereby significantly reduce depreciation, maintaining expense and financial expense, and then reduce production costs more than 20%.
