The specific embodiment
Fig. 1 is the flow chart of the prepreg cutting method of a preferred embodiment of the present invention.Fig. 2 A and Fig. 2 B are the cutting means and the partial schematic diagram that cuts accessory plate of a preferred embodiment of the present invention.Fig. 3 is the sketch map of the rectangle prepreg that cuts front and back of a preferred embodiment of the present invention.Please refer to Fig. 1, Fig. 2 A, Fig. 2 B and Fig. 3.
As shown in Figure 3, the prepreg cutting method that present embodiment provided is used to cut rectangle prepreg 2, to obtain another rectangle prepreg 3.Wherein, the length of the adjacent dual-side of rectangle prepreg 2 can be equal or does not wait, as long as guarantee that the angle between its adjacent side is 90 degree.In addition, the size that cuts another rectangle prepreg 3 that obtains can be carried out suitable adjustment as required.
In the present embodiment, rectangle prepreg 2 has interconnective first and treats that cutting edge and second treats cutting edge.Particularly, as shown in Figure 3, rectangle prepreg 2 to be cut has first side 21, second side 22, the 3rd side 23 and four side 24.At this, cutting edge is treated as first in first side 21, and cutting edge is treated as second in second side 22.Yet the present invention is not limited thereto.In practical application, any two interconnective sides of rectangle prepreg 2 all can be used as first and treat that cutting edge and second treats cutting edge.
In the present embodiment, the prepreg cutting method comprises step S10～S14.At first, as shown in Figure 1, in step S10, provide cutting means 10 be resisted against cutting means 10 cut accessory plate 12.Particularly, shown in Fig. 2 A and Fig. 2 B, cutting means 10 comprises and cuts pedestal 100, baffle plate 101 and cut blade 102.Baffle plate 101 is arranged at and cuts on the pedestal 100.Cutting blade 102 movably is set up in and cuts on the pedestal 100.When cutting, rectangle prepreg 2 to be cut is arranged at and cuts on the pedestal 100, and cut blade 102 can be along cutting rectangle prepreg 2 perpendicular to cutting being directed downwards of pedestal 100.In addition, baffle plate 101 is arranged at a side that cuts blade 102, and the direction that is provided with of baffle plate 101 is parallel to the direction that is provided with that cuts blade 102.Be in the present embodiment, baffle plate 101 is parallel to and cuts blade 102 and on this plane, direction is set in the direction that is provided with that cuts on pedestal 100 planes of living in.
In the present embodiment, shown in Fig. 2 A, cut accessory plate 12 and have first auxiliary side 121, second auxiliary side 122 and the 3rd auxiliary side 123.Wherein, second auxiliary side 122 connections, the first auxiliary side 121 and the 3rd is assisted side 123 and is assisted side 121 perpendicular to first.Included angle A between the first auxiliary side 121 and the 3rd auxiliary side 123 is 90 degree.At this, cut accessory plate 12 and be trapezoidal, therefore, included angle A is the formed angle of extended line of the first auxiliary side 121 and the 3rd auxiliary side 123.Yet the present invention does not limit the shape that cuts accessory plate 12.In other embodiments, cut accessory plate 12 and also can be right angled triangle with 10 degree acute angles.
In the present embodiment; As shown in Figure 1; In step S11, first of rectangle prepreg 2 is treated that cutting edge (first side 21) against to the 3rd auxiliary side 123 of breaking out cut plate 12, makes cutting means 10 cut rectangle prepreg 2 to form first cutting edge 31 along preset direction D.Wherein, preset direction D is parallel to the first auxiliary side 121.In addition, in step S11, the first auxiliary side 121 that cuts accessory plate 12 is resisted against baffle plate 101.In other words, after the first auxiliary side 121 that cuts accessory plate 12 was resisted against baffle plate 101, first of rectangle prepreg 2 treated that cutting edge (first side 21) is just against to the 3rd auxiliary side 123.Like this, can guarantee the location of rectangle prepreg 2, move in the process of cutting to avoid it, thereby be convenient to cut.Simultaneously, can guarantee that also first treats that the angle between the cutting edge (first side 21) and first cutting edge 31 is 10 degree.
In the present embodiment; As shown in Figure 1; In step S 12, second of rectangle prepreg 2 is treated that cutting edge (second side 22) against to the 3rd auxiliary side 123 of breaking out cut plate 12, makes cutting means 10 cut rectangle prepreg 2 to form second cutting edge 32 along preset direction D.In step S12, likewise, the first auxiliary side 121 that cuts auxiliary version 12 is resisted against baffle plate 101.Particularly, behind step S11, only need that rectangle prepreg 2 is rotated to second and treat that cutting edge (second side 22) against the 3rd auxiliary side 123, can continue to carry out cutting operation.Therefore, can guarantee that second cutting edge 32 is perpendicular to first cutting edge 31.
In the present embodiment, as shown in Figure 1, in step S13, make cutting means 10 cut rectangle prepreg 2 along the direction that is parallel to first cutting edge 31.Particularly, in step S13, need remove and cut accessory plate 12, and will pass through first cutting edge 31 that cuts the rectangle prepreg 2 that forms first cutting edge 31 and second cutting edge 32 and be resisted against baffle plate 101, and then proceed to cut.Because the direction that is provided with of baffle plate 101 is parallel to the direction that is provided with that cuts blade 102, therefore, be parallel to first cutting edge 31 at the 3rd cutting edge 33 that cuts back formation.
In the present embodiment, as shown in Figure 1, in step S14, make cutting means 10 cut rectangle prepreg 2 along the direction that is parallel to second cutting edge 32.Particularly, in step S14, only need to cut the rectangle prepreg 2 that is formed with the 3rd cutting edge 33 and rotate to second cutting edge 32 and be resisted against baffle plate 101, and then proceed to cut.Because the direction that is provided with of baffle plate 101 is parallel to the direction that is provided with that cuts blade 102, therefore, be parallel to second cutting edge 32 at the 4th cutting edge 34 that cuts back formation.Like this; As shown in Figure 3, because first cutting edge 31 is parallel to first cutting edge 31 perpendicular to second cutting edge, 32, the three cutting edges 33; And the 4th cutting edge 34 is parallel to second cutting edge 32; Therefore, rectangle prepreg 2 can form another rectangle prepreg 3 after said method cuts, and rectangle prepreg 3 is that to utilize oblique 10 degree to cut rectangle prepreg 2 formed.
In sum, in the prepreg cutting method that preferred embodiment of the present invention provided, utilize and cut accessory plate, can realize that the oblique of rectangle prepreg cuts.Wherein, cutting first auxiliary side of accessory plate and the angle between the 3rd auxiliary side is 10 degree.Like this, the rectangle prepreg that obtains after cutting is cut and forms along four sides, 10 degree that tilt by former rectangle prepreg.The impedance behavior that therefore, can improve the circuit board of being made by prepreg also can reduce the signal interference.
Though the present invention discloses as above with preferred embodiment; Right its is not in order to limit the present invention; Has common knowledge the knowledgeable in the technical field under any; Do not breaking away from the spirit and scope of the present invention, when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking claims person of defining.
