Description

The cutter sweep of printed circuit board (PCB) soft board cutting machine

The utility model relates to a kind of printed circuit board (PCB) soft board cutting machine, particularly a kind of cutter sweep of printed circuit board (PCB) soft board cutting machine.

General traditional circuit printed panel (PCB) soft board cutting is finished by Mould Machining such as cutting die or punching blocks.Cutting die as shown in Figure 1 is for embed the blade mould of required cutting profile on a work mould, utilize blade to implement die cut processing, and punching block as shown in Figure 2 is for making the upper and lower mould of required cutting profile model on the template in advance, utilizing the corresponding pressing clipper circuit of upper and lower mould printed panel soft board.

But; with regard to the Mould Machining of known cutting die or punching block; this cutting die generally embeds the blade operation just need expend half day man-hour; and shape is revised very difficult; machining accuracy is relatively poor; and on being somebody's turn to do; though following punching block machining accuracy is preferable; but on; following punching block is made forming model just need expend 3 to 5 days man-hour; these two kinds of cooked modes add for difform soft board just needs to make different moulds man-hour; die sinking cost of manufacture height; during produced in small quantities; cost does not meet economic benefit; so two kinds of cooked modes of known cutting die or punching block, the cost of manufacture height only is applicable to large-scale volume production; and the making of shaping dies and shape are revised and are difficult for, and its applicability does not meet economic benefit.

In view of this, this creator is based on the demand of circuit printing plate soft board cutting, to be engaged in the industry experience accumulation for many years, be to concentrate on studies to innovate a kind of cutter sweep of circuit printing plate soft board cutting machine, cross problems such as height to solve present circuit printing plate soft board cutting processing cost of manufacture, utilize for this industry demand person.

Main purpose of the present utility model is the cutter sweep that a kind of circuit printing plate soft board cutting machine will be provided, and can save the Mold Making cost, has the high motor-driven conversion of efficient, and its precision height is applicable to various a spot of production, has value on the industry.

The purpose of this utility model is achieved in that

A kind of cutter sweep of printed circuit board (PCB) soft board cutting machine, mainly formed to displacement and displacement mechanism that whirligig the constituted cutter tool of arranging in pairs or groups by directions X linear axes, Y direction linear axes and Z, wherein this directions X linear axes, Y direction linear axes and Z dispose the auxiliary manufacture controller in its path of control to displacement and whirligig, and this Z clamping on the jaw of displacement and whirligig has the cutting tool of angle controlled and direction; It is characterized in that:

This cutting tool is provided with the rectangular plumb cut of a demifacet, and is provided with by first cutting face in the bottom and leads bevel bottom intersection point and constituted one and with the center cutter distance cut point of one side-play amount is arranged, and is provided with second cutting face that is an angle with plumb cut.

This first cutting face and center cutter line are the angle of 20 to 40 degree.

This second cutting face and the formed angle of plumb cut are 10 to 20 degree.

It is made of the utility model the displacement mechanism of X, Y, the Z three-dimensional cutter tool of arranging in pairs or groups, can calculate cutter path with auxiliary manufacture controller according to the soft board drawing, only need to adopt one group of cutter can finish the soft board cutting, and change different procedures and can cut different soft boards.

Yet, with general cutter cut point design, it generally is all the design that falls within center cutter, and so design has its shortcoming, in fact at its technical difficulty that is manufactured with of cut point, because of need grind to form the formed cut point of symmetric form with the cutting inclination angle, generally be difficult for reaching with hand lapping, its cut point more or less all can produce a position offset, so when cutting, can cause the skew of cutting relatively, influence its cutting accuracy.

Because the shortcoming of above-mentioned cutting tool, the technological means that the utility model adopted, design a kind of the cutting tool that the tool demifacet is rectangular, it needs to grind the cut point that demifacet becomes a tool inclination angle, cause cut point and main axle moving center to have a side-play amount, so that cut point is at center cutter, easier machining control on cut point is made need not be considered a whether demand factor that fixes on the center of cut point.

The cutting tool of Gou Chenging by this, implementing on the cutting operation, must be subjected to Z to control its angle and direction to displacement and whirligig, calculate cutter path with this auxiliary manufacture controller according to the side-play amount of cut point in when cutting, the cut point of cutter can precisely be controlled to be fallen within on the cutting pattern, keep first cutting face in cutting path the place ahead, lead bevel in the cutting path rear, plumb cut is in the cut substrate inboard, second cutting face is in the cut direction in the cut substrate outside, reach optimized forward cutting power, help dust lead and the effect of cutting control easily, cause the soft board cutting face can obtain preferable section precision.

Therefore, accurately control the size of cutting soft board in order to make cutter, side-play amount according to the cutter cut point contrasts mutually with the desire cutting pattern, calculate cutter path by auxiliary manufacture controller, so that precisely controlling, the cut point of cutter falls within on the cutting pattern, utilize cutter half mask right angle and cut point to have a design of forward cutting the inclination angle, make cutter to have dust lead and the effect of cutting control easily, reach optimized cutting power, thereby reach the saving die manufacturing cost, have the high motor-driven conversion of efficient, its precision height, be applicable to various strength production, have the purpose of value on the industry.

The utility model is simple in structure, is a kind of die cost of saving, and shortens man-hour, and can cooperate auxiliary manufacture controller to revise the cutter sweep of cutting profile, its cutting section precision height, and be applicable to various a spot of production, and the tool practicality.

Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.
