Accompanying drawing explanation
Fig. 1 is that the present invention reduces the flow chart producing the method preferred embodiment of burr in rigid-flex combined board gong plate process.
Fig. 2 is structural representation when pasting polyester film in method of the present invention on rigid-flex combined board.
Embodiment
The invention provides the method and the rigid-flex combined board that reduce and produce burr in rigid-flex combined board gong plate process, for making object of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is that the present invention reduces the flow chart producing the method preferred embodiment of burr in rigid-flex combined board gong plate process, and it comprises step:
S1, stick one deck polyester film in the flex plate plate face of rigid-flex combined board;
S2, employing gong plate mode are shaping, use gong cutter, tear polyester film after completing gong plate when gong plate.Gong blade row bits performance is better.
The cutter footpath of described gong cutter is 0.8mm, 1.0mm, 1.2mm, 1.4mm or 1.6mm, and namely the edge of a knife diameter of gong cutter is 0.8mm, 1.0mm, 1.2mm, 1.4mm or 1.6mm.
Specifically when at gong plate, first use the gong cutter in 1.6mm cutter footpath to remove waste material, then the gong cutter refine using 1.0mm cutter footpath once.
Described polyester film is red polyester film.Polyester film of the present invention, it is compared with other adhesive tape, high temperature resistant (resistance to 170 DEG C), and glue-line does not transfer to plate face, and the resistance to temperature 70 C of other adhesive tape, glue-line is easily transferred to plate face, affects quality.The technological process of polyester film: chip bunker is carried-wet in section-vibrating screen-apparatus for separating metals-one-level pulse conveying-batch mixing feed bin-secondary pulse.Polyester film take PETG as raw material, adopts extrusion molding to make sheet, then through thin-film material that biaxial tension is made.The thickness of polyester film can be 20 μm.Described polyester film can adopt electrical insulation film, and it can tolerate higher temperature.
Preparing in polyester film process, vertical stretching-machine can be adopted first to carry out vertical stretching, and vertical drawing process is divided into preheating section, stretch section, cooling section, sizing section, preheating section makes temperature control at 80 DEG C, to carry out preheating, stretch section is carrying out single-point stretching between roller and quick roll at a slow speed, and the temperature of quick roll is 80 DEG C, the temperature of roller is 20 DEG C at a slow speed, cooling rapidly after stretching, reduce and solve, temperature is cooled to 20 DEG C, then suitable raised temperature, reduces film longitudinal contraction rate.Its diameter of roller that preheating adopts is about 600mm, and roller number is 4 ~ 10, such as 5.The sheet material that longitudinal stretching obtains carries out cross directional stretch through transverse drawing mill again.Cross directional stretch is also divided into four-stage: preheating section, stretch section, sizing section, cooling section, preheating section temperature is at about 90 ~ 120 DEG C (as 100 DEG C), stretch section temperature is at 130 ~ 150 DEG C (as 140 DEG C), sizing section temperature is at 180 ~ 240 DEG C (as 200 DEG C), to reduce film heat shrinkable, cooling section temperature is 50 ~ 80 DEG C (as 60 DEG C), prevents film from producing creep at a higher temperature, thus improves the performance of film.The final stage of cross directional stretch is cooling section, its principle be utilize blower fan suck clean fresh air and and portion circulated air mix, then the heat exchanger through being connected with cooling water (30 DEG C) cools, cooled cavity blows to the surface of film from upper and lower both direction, and the effect of cooling prevents film from producing creep at a higher temperature.Shaped by heat setting machine after cooling section, the temperature of thermal finalization at 190 ~ 250 DEG C, the processing time be 3 ~ 6s(as 220 DEG C, 5s).
When carrying out pad pasting, laminator can be used polyester film 200 to be attached to the plate face of flex plate, and as shown in Figure 2, flex plate 110 and rigid plate 120 form rigid-flex combined board 100, polyester film 200 are attached to the plate face of flex plate 110.
Laminator comprises frame, the labeling cylinder be arranged in frame, unreeling wheel, peel plate, guide roller, roller, servomotor, friction wheels, winding wheel, tool locating piece, labeling cylinder is wherein used for getting polyester film and being attached to flex plate plate face, labeling cylinder head shape has vacuum slot, when feeding, peel plate makes polyester film be separated with base stock (sticking together with base stock during initial condition), the vacuum slot of labeling cylinder head holds polyester film, labeling cylinder is descending, pad pasting is attached to flex plate plate face.Unreeling wheel is follower, and for laying the polyester film of drum, guide roller is then for playing guiding and the positioning action of the polyester film of drum.Roller also play the guiding role.Servomotor provides power for guide roller and winding wheel, realizes accurate feeding by servo controller.In friction wheels, one is rubber rollers, and one is metallic roll.Be used for driving polyester film, realize normally fitting.Winding wheel is the driving wheel of friction wheels, and effect is the base stock after rewinding labeling.Tool locating piece then can be used for location, having elongated slot, adjustable bonding position bottom it, realizes accurately locating.
In sum, method of the present invention, compared with traditional gong plate mode, eliminates the operation of manual repair's burr, and every block plate is saved time 5-15min; And compared with traditional die-cut mode, product quality improves, and avoids product to collapse oil, layering, edge impulse-free robustness, round and smooth.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection range that all should belong to claims of the present invention.
