Description

The manufacture method of high accuracy flexible circuit die cutting plate

Technical field:

The present invention relates to a kind of manufacture method of die cutting plate, particularly relate to a kind of manufacture method of high accuracy flexible circuit die cutting plate.

Background technology:

The employed die cutting plate of being made up of glued wood and cutter material mainly is the sheet material that is used to process the cutting packing box at present, but, along with science and technology development, mobile phone, notebook computer, digital camera, video camera, printer, Medical Devices etc. are used widely, and, will be more and more universal, process cutting owing to adopt die cutting plate, its precision height, speed is fast, to difformity, the variation of size is flexible, thereby, to mobile phone, laptop computer, digital camera, video camera, printer, the profile of inner flexible circuit boards such as Medical Devices also begins imagination and enables die cutting plate and carry out cross cutting, this application for the developing die cutting plate is the prospect with wide society benefit and economic benefit, but, flexible PCB different, size gap great disparity, do and become ten thousand changes, and, the material of forming flexible PCB also has nothing in common with each other, like this, to glued wood, the requirement of cutter material is higher, particularly processing fluting on glued wood, the more careful complexity of row's cutter technology, especially will reach suitable precision and cooperate, this is an easy thing anything but.

Summary of the invention:

The objective of the invention is to provide a kind of manufacture method of improved a kind of high accuracy flexible circuit die cutting plate, it not only can implement cross cutting processing to inner flexible circuit boards such as mobile phone, notebook computer, digital camera, video camera, printer, Medical Devices effectively, and, the precision height of die cutting plate, long service life, simultaneously, the production efficiency and the quality precision of inner flexible circuit boards such as mobile phone, notebook computer, digital camera, video camera, printer, Medical Devices have also been promoted greatly.

The object of the present invention is achieved like this: the manufacture method of high accuracy flexible circuit die cutting plate of the present invention, selected manufacturing equipment is by CAD designing and mapping system, the laser graphics cutting machine, automatic rulecutter, automatic rule bender, row's cutter machine, compositions such as bed die maker, the bulk material of processing die cutting plate is a glued wood, described glued wood should be selected surperficial free from flaw for use, no impression and other people are pollution etc., the every layer thickness of described glued wood is greater than 1.5 millimeters, in every meter plate is wide, the lath number is less than three, when described glued wood is made, press pressure is greater than 13 kilograms, the glacing flatness of described glued wood requires to reach every meter and is limited to 0.5 millimeter up and down, described core layer number is looked the specific requirement decision, as when adopting higher cutter material, in order to improve the stability of cutter material on glued wood, just need thicker glued wood, the moisture content of described glued wood is 10～12%, described glued wood should be 100% birch, be designed to the cross cutting manuscript according to the finished figure that is provided, because flexible circuit board shape is different, the graphics process that each position of figure is all needed to carry out machinability, different materials to flexible PCB can adopt zoom technology, minimum figure is carried out stability, the PROCESS FOR TREATMENT of firmness, in addition according to the dense degree of cutter line, be distance and the interior quantity of arranging cutter of unit distance between cutter and the cutter, the length difference of cutter line, linearity requirement, the water content of plank and the characteristic of density, after carrying out analysis-by-synthesis, determine the groove width controlling value of laser cutting, described then CAD designing and mapping system is to the flexible PCB structural design that will make and the accurate figure of drawing out, when the processing die cutting plate, earlier described glued wood is sent into the laser graphics cutting machine and carries out the sample cutting, after the sample cutting, cutting width and perpendicularity through check meet required precision after, again according to this described glued wood is formally cut by the graphics processing of design, described cutter material high-quality steel at the material behavior of different flexible PCBs, requires the linearity of tool setting material, the knife edge, the average undulating value of center line (Ra), tool-point height poor (Rmax) and the crucial numerical value of 10 average undulating values (Rz) carry out strictness control, need carry out corresponding selection, fineness because of product design, linearity directly influences the precision of size, and the back cuts into required steel knife by designing requirement with the cutter material by automatic rulecutter, for guaranteeing the size conforms following process demand of steel knife, the issuable elongation of reply, should fully take in and make accurate numerical value on calculating, the steel knife by automatic rulecutter is cut off bends to required figure by automatic rule bender again, enter knifing system again, just arrange cutter in the figure groove that is occurred on the glued wood after being cut, when row's cutter, by different cross cutting figure and die cut material by the laser graphics cutting machine, formulate different processing technologys, in row's cutter process,, adopt the bridge opening counter-point for guaranteeing the linearity of the knife edge, be about to the bridge opening position and be arranged on same straight line, control bridge opening quantity simultaneously, to reduce the extruding between cutter and the cutter, according to the flexural property degree of crook of cutter moulding and the control requirement of dimensional accuracy, adopt high-precision blade " fluting technology ", carry out less than the crooked of R0.5 and adopt " grinding technique ", guarantee the intact of knife edge interface and merging precision, with " bending techniques " processing of finalizing the design, use " the firm method of blade " again, " row's cutter sequential method ", " knife edge facture " technology is arranged cutter processing, finally guarantee the precision of flexible circuit die cutting plate manufactured size, when figure is the corner, because of on blade, slotting earlier, and then steel knife curved wedge angle, to avoid steel knife deformation and product size error, steel knife takes place more in short-term, have enough fastness for making steel knife, the steel knife suitable size that when cutting knife, lengthens earlier, row's knife edge of regrinding behind the cutter is when making special-shaped product, for ensureing the useful life of steel knife in the figure groove of die cutting plate really, must adopt integrated steel knife to bend, row row cutter has been arranged cutter again, and die cutting plate also machines.

Because the present invention is not to use the manufacture method of existing die cutting plate, but all implemented important breakthrough in design and row's cutter technology of the body glued wood of die cutting plate, cutter material, figure, thereby the high accuracy flexible circuit die cutting plate of realizing manufacturing can cut out flexible PCBs such as high-precision mobile phone, notebook computer, digital camera, video camera, printer, Medical Devices.
