Specific embodiment
Please join shown in Fig. 3 and Fig. 4, present invention is disclosed a kind of boring method of printed circuit board and its rig, its
Described in rig include lathe table top 1, boring machine (not shown) and the gas in order to fixation printed circuit board 2 hole to be drilled
Folder 3.Described gas folder 3 and the described equal fixed in position of printed circuit board 2 hole to be drilled are on described lathe table top 1, and described gas folder 3
Can be rotated in the plane that lathe table top 1 is located together with described printed circuit board 2 hole to be drilled.
Described printed circuit board 2 hole to be drilled has some positions hole to be drilled, including the first hole position 21 and
Two hole positions 22.In illustrative embodiments of the present invention, the plane that described lathe table top 1 is located is horizontal plane, described first hole
The coordinate position of position 21 is (x1, y1), and the coordinate position of described second hole position 22 is (x2, y2).
Boring method with regard to the printed circuit board of the present invention is described below.The boring method of printed circuit board of the present invention
Comprise the steps:
A () printed circuit board 2 hole to be drilled is placed on lathe table top 1；
B () starts boring machine, be processed according to program prepared in advance；
Wherein, move to before target location holed in described boring machine, described printed circuit board 2 hole to be drilled exists
Rotate a certain angle in the plane that lathe table top 1 is located, to shorten the traveling time of described boring machine, improve drilling efficiency.
Please join shown in Fig. 3 and Fig. 4, in step (a), described printed circuit board 2 hole to be drilled is fixed on gas folder 3.
In described printed circuit board 2 rotary course hole to be drilled, described gas folder 3 is together with described printed circuit board 2 hole to be drilled
Rotation.
Specifically, in step (a), two pin holes 23 are opened up simultaneously at the two ends of described printed circuit board 2 hole to be drilled
Introduce pin 4 to be positioned on described lathe table top 1, one of pin 4 is put in pin folder 5, needle tray put into by another pin 4
In 6.The two ends of described printed circuit board 2 hole to be drilled respectively by cylinder moving come fixing pin 4, and then realize finally solid
Fixed.
After described printed circuit board 2 hole to be drilled is fixing, boring machine is holed according to drilling program prepared in advance.
In drilling program, the coordinate of hole position is set, boring machine passes through to illustrate x-axis and being synchronized with the movement of y-axis direction searches out hole
Position (i.e. target location) after holed.Boring machine, before moving along x/y direction of principal axis, gas is pressed from both sides 3 together with print hole to be drilled
Circuit board 2 processed rotates a certain angle by certain direction, and (the concrete anglec of rotation can be set in drilling program α, with
Big degree improves drilling efficiency).
Hereinafter beneficial effects of the present invention are described in detail.
Please join shown in Fig. 2, the coordinate of the first hole position 21 is (x1, y1), the coordinate of the second hole position 22 be (x2, y2) it is assumed that
Y1=y2, then the distance between this two hole positions s1=x2-x1.If according to boring method of the prior art, process
During the second hole position 22, the movement time t of x-axisx=s1/vx；Because the first hole position 21 is parallel with the second hole position 22, therefore the motion of y-axis
Time ty=0；So, t2=max (t process time of the second hole position 22x, ty) + tDrilling time.
Please join shown in Fig. 5, according to the boring method of the present invention, described gas folder 3 is together with described printed circuit board 2 hole to be drilled
In certain direction after anglec of rotation α, the move distance of x-axis becomes s by s1x, movement time tx’=sx/vx, the motion of y-axis away from
From becoming sy, movement time ty’=sy/vy, then, the t2 ' process time=max (t of the second hole position 22x’, ty’) + tDrilling time.
For same boring machine, generally, speed v of boring machinex=vy, the drilling time t of boring machineDrilling timeUnanimously.This
Bright boring method can make boring machine synchronous vertical motion in x-axis and y-axis direction, because s1 is hypotenuse, sxWith syFor right angle
Side, then inevitable s1 > sx, s1 > sy, thus can release t2 ' < t2.
In sum, when boring machine can be reduced using the boring method of the present invention be synchronized with the movement on x-axis and y-axis direction
The time mutually waiting；Optimal, when gas folder 3, together with described printed circuit board 2 hole to be drilled, the anglec of rotation reaches in certain direction
During to α=45 degree, sx=sy, now can be completely eliminated when boring machine is synchronized with the movement on x-axis and y-axis direction mutually wait when
Between, farthest improve working (machining) efficiency.
It should be understood that above example is merely to illustrate the present invention and not limits technical side described in the invention
Case, although this specification with reference to the above embodiments to present invention has been detailed description, the common skill of this area
Art personnel should be appreciated that person of ordinary skill in the field still can modify to the present invention or equivalent, and
All, without departing from the technical scheme of the spirit and scope of the present invention and its improvement, all should be covered in scope of the presently claimed invention
Interior.
