Then, adjust for degree of depth adjustment part 34 details that cutter 33 carries out the effect of the degree of depth cut off to be described.
In Fig. 5 (a) and Fig. 5 (b), schematically show the state that the knife unit 50 as comparative example cuts off cut-off thing 17.
In Fig. 6 (a) and Fig. 6 (b), schematically show the state that knife unit 30 cuts off cut-off thing 17.In figure 6, only cutter 33 and cut-off thing 17 periphery is illustrated.
Below, about cut-off thing 17 for only wanting to cut off resin film 17a, not wanting the situation cutting off brittle substrate 17b to be that example is described.Namely, for (following by becoming the layer cutting off object, be called " cut-out object layer ") be set to resin film 17a, cut off the situation that the layer (hereinafter referred to as " non-severed object layer ") of object is set to brittle substrate 17b be described not becoming.
As shown in Fig. 5 (a) and Fig. 5 (b), knife unit 50 is formed by retaining member 51, pin 52 and cutter 53.Cutter 53 is fixed relative to retaining member 51 by pin 52.Cutter 53 has the planar portions 54 vertical relative to the crest line of sword front end 43.In knife unit 50, wanting the situation cutting off resin film 17a, becoming and making planar portions 54 contact with brittle substrate 17b and cutter 53 is moved horizontally.
In knife unit 50, cutter 53 moves horizontally in non-rotary situation.Therefore, inscribe is carried out to cut-off thing 17 and has any problem, must carry out circumscribed.Therefore, when carrying out the cut-out of cut-off thing 17, its position started easily is restricted.
So-called " inscribe " represents the method carrying out from the ora terminalis inside of comparatively cut-off thing 17 cutting off.So-called " circumscribed " represents from the outside rotary cutter of the ora terminalis of cut-off thing 17 to carry out the method cut off.
In knife unit 50, must regulate with the height of cut-off thing 17 planar portions 54 of cutter 53.
Specifically, before starting to cut off, in the outside of cut-off thing 17, must carry out considering the thickness of resin film 17a, make the operation that the planar portions 54 of cutter 53 is consistent with the height of brittle substrate 17b simultaneously.
As knife unit 50, contacting the occasion not wanting the formation cutting off layer not making cutter 53, being easily subject to the impact in the place loading cut-off thing 17.
Specifically, when cutting off cut-off thing 17, being subject to the impact of the flatness of the platform 16 loading this cut-off thing 17, easily producing deviation in the degree of depth cutting off cut-off thing 17.In addition, object will cut off laminated on the situation of brittle substrate, even therefore the small concavo-convex of brittle substrate surface also have same impact.
In addition, in knife unit 50, the hardness of cutter 53 must be made lower than the hardness (be at least and cut off near face that object layer contacts) of non-severed object layer.This is because the hardness at cutter 53 is higher than the situation of the hardness of non-severed object layer, will make the event of this non-severed object layer breakage (scuffing).
Specifically, the hardness of cutter 53, must higher than the hardness of resin film 17a, simultaneously lower than the hardness of brittle substrate 17b.
If make the hardness of cutter 53 low, then its life-span will reduce.
On the other hand, as shown in Figure 6, for carrying out by knife unit 30 situation cutting off cut-off thing 17, the curved face part 37 of the degree of depth adjustment part 34 of holder 31 and the surface contact of resin film 17a.Once curved face part 37 and the surface contact of resin film 17a, then determine the position (highly) of knife unit 30 relative to cut-off thing 17.Once the position of knife unit 30 is determined, then determine the position of cutter 33, make to cut off cut-off thing 17 from the part that degree of depth adjustment part 34 is outstanding among this cutter 33.
In this manner, the degree of depth that cutter 33 cuts off cut-off thing 17 is adjusted.
In knife unit 30, cutter 33 is disc-shape and is rotatable.Therefore, it is possible to carry out inscribe to cut-off thing 17.
As knife unit 30, on one side contact cut object layer surface, while carry out the situation of the formation cut off, with contact non-severed object layer while carry out compared with the situation cut off, not more being vulnerable to load the place of cut-off thing 17 or the small concavo-convex impact on non-severed object layer surface.
