Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to Fig. 1 and Fig. 2; The utility model provides a kind of film location structure, and it comprises the film 10, substrate 20 and location division 30, wherein; Four angles of the film 10 are equipped with first pilot hole 11; Four angles of substrate 20 are provided with second pilot hole 21 corresponding with first pilot hole 11, and location division 30 wears first pilot hole 11 and second pilot hole 21, and the film 10 and substrate 20 are fixed together.
In an embodiment of the utility model; One first pilot hole 11 is respectively established at four angles of the film 10; And wherein the relative position of first pilot hole 11 at three angles is identical; The relative position of first pilot hole 11 at the 4th angle is different with the relative position of first pilot hole 11 at other three angles, can make the usefulness of fool proof whereby, and location efficiency is provided.
For embodying the fool proof effect of the film 10, first pilot hole 11 at its four angles can also be provided with as follows: it is more than the quantity of first pilot hole 11 of other triangle that three angles of the film 10 have 11, the four angles of first pilot hole of equal number.Such as, one first pilot hole 11 is respectively established at wherein three angles of the film 10, and the another one angle is provided with two or this pilot hole, realizes fool proof effect preferably whereby.
Need explanation; Second pilot hole 21 on the substrate 20 and first pilot hole, 11 couplings are provided with; First pilot hole 11 that is each angle of the film 10 is to adopt which kind of mode to be provided with, and second pilot hole 21 at each angle of substrate 20 adopts identical set-up mode with it, among the embodiment of the utility model; First pilot hole 11 is identical with the aperture of second pilot hole 21, can make location division 30 better fixing whereby.
The concrete manufacturing process of the utility model is following: 1) light is painted and is produced the film 10 (the black film, the yellow film all can); Four jiaos first pilot hole 11 is set on the film 10 technology limits; And the aperture of first pilot hole 11 generally is made as 3mm; It is individual than other three many 1-2 in angle that hole count is set at one of them angle, to make the usefulness of fool proof; 2) use X-Ray (roentgen-ray) machine to each first pilot hole 11 of the film 10 boring of practicing shooting; The target practice bit is selected the diameter model identical with the aperture of first pilot hole 11 for use; 21 of each second pilot holes on the substrate 20 get out through rig, and the aperture of second pilot hole 21 is identical with the also footpath of first pilot hole 11; 3) first pilot hole 11 is passed in location division 30, preferably, the location division 30 of the utility model is the PIN nail, and it comprises pad 31 and ailhead 32; Like Fig. 3, and the diameter of ailhead 32 is than the first pilot hole little 0.02mm in 11 apertures, and the height of ailhead 32 is not more than the thickness of substrate 20; During installation, the non-medicine face of PIN nail from the film 10 passed, PIN ailing head 32 is at medicine face; Pad 31 is at non-medicine face, and then with adhesive tape the pad 31 and the film 10 is bonded together, and the PIN nail is installation; 4) film of PIN being followed closely after installing 10 lies in a horizontal plane on the exposure machine glass table top, fixes with adhesive tape, then the nail of the PIN on the corresponding one by one film 10 of second pilot hole 21 on the substrate 20 is overlapped, and can produce.
