Abstract
The invention discloses a kind of cutting efficiency height, edge-smoothing, high yields, it is not easy to generate the cutting method for breaking angle, step is：Step 1: pasting acid etch protective film in panel both sides；Step 2: the protective film that using laser cutting machine both sides above and below panel are located at display screen unit periphery carries out heat fusing so that the glassy layer of display screen periphery exposes；Step 3: being etched using panel to be put into chemical etching device, required cutting profile is etched；Step 4: panel to be integrally divided into several display screen unit small pieces using sliver apparatus sliver or the manual sliver that carries out；Step 5: intensive treatment is removed and carries out to the extra material in display screen unit edge cut into pieces, to remove crackle and burr；Step 6: carrying out membrane removal, washing and drying treatment to display screen unit.
Description
Technical field
The present invention relates to a kind of cutting methods of panel display board.
Background technology
Abnormity cutting is that panel display board (TFT-LCD, OLED) completes upstream process, after the completion of manufacture, carries out mould
An essential procedure before group processing, with application of comprehensive screen in mobile phone, display screen top need to be vacated and be used for
A large amount of uses of display screen, importance are outstanding day by day in the region of installation mobile phone front camera and automobile.
Existing cutting method has mechanical patterning method as described in patent application 201180058971.6, or laser cutting
Method, not only cutting efficiency is not high, and cut edge is not smooth enough, and compression strength is inadequate, and when cutting is also easy to brokenly angle, and yield is not
Height, when being used in the cuttings such as the display screen of for example comprehensive screen mobile phone of special-shaped panel, these are particularly problematic.
Invention content
The technical problem to be solved by the present invention is to：A kind of cutting method of panel display board is provided, cutting can be made to imitate
Rate height, edge-smoothing, high yield, it is not easy to generate and break angle.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of cutting side of panel display board
Method, step are：
Step 1: pasting acid etch protective film in panel both sides；
Step 2: the protective film that using laser cutting machine both sides above and below panel are located at display screen unit periphery is heated
Melt so that the glassy layer of display screen periphery exposes；
Step 3: carrying out chemical etching using panel to be put into chemical etching device, required cutting profile is etched,
The interconnecting piece thickness between adjacent display screen unit is set to be no more than 0.8mm；
Step 4: carrying out sliver using sliver apparatus sliver or by hand, that panel is integrally divided into several display screen units is small
Piece；
Step 5: intensive treatment is removed and carries out to the extra material in display screen unit edge cut into pieces, with removal
Crackle and burr；
Step 6: carrying out membrane removal, washing and drying treatment to display screen unit.
The beneficial effects of the invention are as follows：Due to having pasted whole acid etch protective film on panel both sides, and use laser
Redundance is melted, it is very quickly and easily that display screen unit covering protection is good, panel is then put into chemical etching liquor
In be etched, etch, and the smooth of the edge high compared with the method cutting efficiency of traditional laser cutting or machine cuts, more will not
Stress concentration leads to the generation of fragmentation situation when occurring because of cutting, while reducing whole production cost.
Description of the drawings
Fig. 1 is the schematic diagram (panel front) of step 2 in the present invention.
Fig. 2 is the schematic diagram (panel sides) of step 3 in the present invention.
In Fig. 1 to Fig. 2：1. panel, 2. display screen units, 3. protective films, 4. interconnecting pieces.
Specific implementation mode
Below in conjunction with the accompanying drawings, detailed description of the present invention specific embodiment.
A kind of cutting method of panel display board, step are：
Step 1: pasting acid etch protective film in panel both sides or applying Protection glue (such as PET film, PE films, PP films).
Step 2: the protective film that using laser cutting machine both sides above and below panel are located at display screen unit periphery is heated
Melt so that the glassy layer of display screen periphery exposes, and sees Fig. 1；
Step 3: carrying out chemical etching using panel to be put into chemical etching device, immersion way can be used, can also make
With spray mode (widely used for current display screen technique, to repeat no more).It is whole to magnify plate top and bottom while etching, etch institute
The cutting profile needed, is shown in Fig. 2, and the interconnecting piece thickness between adjacent display screen unit is made to be no more than 0.8mm；
Step 4: carrying out sliver using sliver apparatus sliver or by hand, that panel is integrally divided into several display screen units is small
Piece；
Step 5: (mechanical means or chemistry can be used to the removal of the extra material in the display screen unit edge cut into pieces
Method) and intensive treatment is carried out, to remove crackle and burr；Intensive treatment, which can be chemical etching, makes its edge surface light
It is whole, its surface finishing can also be made by the way of mechanical lapping；
Step 6: carrying out membrane removal, washing and drying treatment to display screen unit.
The principles and effects of the invention are only illustrated in the above embodiments, and the implementation that part uses
Example, and is not intended to limit the present invention；It should be pointed out that for those of ordinary skill in the art, not departing from wound of the present invention
Under the premise of making design, various modifications and improvements can be made, these are all within the scope of protection of the present invention.
