Embodiment
Below, the structure of boring device of the present invention is described with reference to Fig. 1～Figure 11.Earlier overall structure is generally illustrated.In this boring device, six perforate mechanisms 2 with perforate on plate workpiece 1, keep this plate workpiece and be transported to the injection mechanism 3 of this perforate mechanism, be arranged to the image mechanism 4 of one respectively with this perforate mechanism, and the travel mechanism 5 that each perforate mechanism is moved independently of each other.And, boring device has the image processing mechanism 6 of the shooting results of processing image mechanism 4 as shown in figure 10, in the time of the driving of calculating the calculation mechanism 7 of result of this image processing mechanism and control image mechanism 4 and injection mechanism 3, according to the controlling organization 8 of the driving of the result of calculation control perforate mechanism 2 of calculation mechanism 7 and travel mechanism 5.Below, respectively each mechanism is described in detail.
For convenience of explanation, begin explanation from injection mechanism 3.As shown in Figure 1, the horizontal rail 31 that injection mechanism 3 has on the pedestal 100 that is fixed on the supporting boring device, extend towards the left and right directions of Fig. 1 (below be called " Y direction "), guiding the arm 32 that can move in the Y direction perpendicular to the direction of this horizontal rail (below be called " Z direction ") and by this horizontal rail, and shift-out mechanism 33.Arm 32 moves along the Y direction by link 34 with shift-out mechanism 33 with linking into an integrated entity integratedly.In addition, arm 32 and shift-out mechanism 33 move towards the Y direction by servomotor 35 and feed screw (not shown).
The chuck 36 that absorption type keeps plate workpiece 1 is installed in the lower end of arm 32.Chuck 36 has connecting plate 361, coincides with respectively and is fixed to jig plate 362 and adsorption plate 363 below this connecting plate by Screw.Connecting plate 361 descends, rises towards the Z direction by spring 365 under the effect that is arranged at the cylinder 364 on the arm 32.Connecting plate 361 moves by hollow cylinder parts 366 guidings that are arranged at arm 32 lower ends the Z direction.
According to Fig. 6 and Fig. 7, the detailed construction of jig plate 362 and adsorption plate 363 is described.Fig. 6 is the concept map of the structure of jig plate 362.That is, the following a of jig plate 362 is flat rectangular shape, and central authorities in its lower section form rectangular channel b, form elongated attraction groove d1, d2, d3 respectively in the position, the left and right sides of this rectangular channel.And, attract groove d1 and rectangular channel b to be communicated with by gas leakage groove e1, attract groove d1 and attract groove d2 to be communicated with by gas leakage groove e2, attract groove d2 to be communicated with by gas leakage groove e3 with attracting groove d3.The bottom land of rectangular channel b about two places be provided with the open pore c that is communicated with not shown vacuum pump.
In addition, connect to form the yielding hole g of the drift of a plurality of datum hole f and perforate described later mechanism 2 on the jig plate 362.The mode that adsorption plate 363 is posted by the following a of jig plate 362 is installed with, and is provided with the through hole 326a (with reference to Fig. 7) of a plurality of absorption plate workpieces 1 at rectangular channel b and attraction groove d1～d3 opposite position with jig plate on this adsorption plate.
At this, the effect of jig plate 362 is described according to Fig. 6.The mode that jig plate 362 can clamping adsorption plate 363 is adsorbed the three kinds of plate workpieces 11,12,13 that vary in size of flat shape respectively selectively.And the plate workpiece 13 of flat shape maximum becomes the shape that covers all attraction groove d1～d3, attracts groove being kept by adsorption plate 363 absorption types by all these.In addition, flat shape becomes the shape that can not cover attraction groove d3 less than the plate workpiece 12 of plate workpiece 13, and plate workpiece 12 is under the state that is kept by adsorption plate 363 absorption, by attracting the gas leakage groove e3 between groove d2 and attraction groove d3, suction extraneous air.And, flat shape becomes to cover less than the plate workpiece 11 of plate workpiece 12 and attracts groove d2, the shape of d3, and plate workpiece 11 is under the state that is kept by adsorption plate 363 absorption, by attracting the gas leakage groove e1 between groove d1 and the rectangular channel b, suck air outside.
That is, plate workpiece 12 is being adsorbed under the state that keeps by adsorption plate 363, the end face crosscut of plate workpiece 12 gas leakage groove e3, and e3 sucks air outside by the gas leakage groove.In addition, plate workpiece 11 is under the state that is kept by adsorption plate 363 absorption, and the end face crosscut gas leakage groove e1 of plate workpiece 11 by gas leakage groove e1, sucks air outside.If these gas leakage grooves e1, the channel section of e3 is long-pending less, is restricted because of the gas leakage groove dwindles from outside amount of air drawn.Therefore, in order to increase the attraction area of plate workpiece 1, even when strengthening the area that attracts groove d1～d3, if because of gas leakage groove e1, e3 has dwindled the inflow path of air, but the soakage of limit air can suppress the reduction of the suction of plate workpiece 1.
But preferably, gas leakage groove e1～e3 groove width is separately set for identical and channel section separately amasss identical, perhaps the groove width of the gas leakage groove of inboard is set for groove width greater than the gas leakage groove in its outside, and the channel section of inboard gas leakage groove long-pending set for greater than the channel section of the gas leakage groove in its outside long-pending.
That is, plate workpiece 12 is by rectangular channel b and attract groove d1, and d2 attracts, and 11 of plate workpieces pass through rectangular channel b and attract.And the attraction area of plate workpiece 11 is compared with the attraction area of plate workpiece 12, just attracts groove d1, and the degree of d2 diminishes.In addition, the attraction area of plate workpiece 11 is less than the attraction area of plate workpiece 12, but the size of tabular workpiece 11 is only slightly little than the size of plate workpiece 12, because of plate workpiece 11 is lighter, can be adsorbed reliably by adsorption plate 363 and keep plate workpiece 11.In addition, if the channel section of inboard gas leakage groove is long-pending set for long-pending identical or bigger slightly with the channel section of the gas leakage groove in its outside than it, then when plate workpiece 12 is kept by adsorption plate 363 absorption, can not be subjected to the gas leakage groove e2 of its inboard, the restriction of e1 by gas leakage groove e3 amount of air drawn.In addition, if the channel section of inboard gas leakage groove is long-pending set for long-pending identical with the channel section of the gas leakage groove in its outside, then when keeping plate workpiece 12 by adsorption plate 363 absorption, by gas leakage groove e3 amount of air drawn can be when keeping plate workpieces 11 by adsorption plate 363 absorption, groove e1 amount of air drawn is identical by leaking gas, the absorption hold mode of plate workpiece 11,12 can be detected simply by single pressure sensor.
Gas leakage groove e1, e2, e3 are not limited to one separately, and as shown in Figure 7, every kind all can be provided with a plurality of.So under the situation, set for long-pending identically or bigger, then can obtain the effect identical with above-mentioned situation than it with the accumulation channel section of the gas leakage groove in the outside if the accumulation channel section of inboard gas leakage groove is long-pending.
Fig. 7 illustrates an example of the jig plate 362 and the adsorption plate 363 of actual use.In addition, part same as shown in Figure 6 is marked by identical symbol.On jig plate 362, be provided with datum hole f, the yielding hole of the drift of double as perforate described later mechanism 2 and to the identification of mark on the plate workpiece 1 described later perforation slotted hole g with mark through hole for shooting, and with the identification of mark on the plate workpiece 1 perforation slotted hole h with mark special use for shooting.On adsorption plate 363, with the datum hole f of jig plate 362, connect slotted hole g, the corresponding position of h forms than datum hole f, connects slotted hole g, h wants big yielding hole, simultaneously, with the corresponding position of each groove (being shown in dotted line) that is positioned on the jig plate 362 on be provided with a plurality of through hole 362a.
For jig plate like this 362 owing to have also that a forms rectangular channel b and attracts groove d1 below it, d2, d3 and as the function of together adsorbing the anchor clamps 36 that keeping plate workpiece with adsorption plate 363, just needn't be provided with the plate that together adsorbs the special use that is keeping plate workpiece 1 with adsorption plate 363, reduce part count, reduced cost.In addition, jig plate 362 is not limited to the function that double as and adsorption plate 363 together adsorb the anchor clamps 36 that keeping plate workpiece, can be used as special-purpose member and is arranged on the anchor clamps 36.
Below, shift-out mechanism 33 is described.
Shift-out mechanism 33 is the structure of adsorbable maintenance plate workpiece 11,12,13, and its basic structure is identical with injection mechanism 3, omits its explanation at this.
In addition, shift-out mechanism 33 can be the structure of adsorbable maintenance plate workpiece 11,12,13, can use and omit perforation slotted hole g, and the sheet material of the absorption special use of h or datum hole f replaces jig plate 362.
Next, with reference to Fig. 1～Fig. 5, to six perforate mechanisms 2 of perforate on plate workpiece 1, be arranged to the image mechanism 4 of one with this perforate mechanism respectively, the travel mechanism 5 that each perforate mechanism is moved independently of each other describes.Perforate mechanism 2 is respectively equipped with three in the both sides of the operation post 101 that is fixed in pedestal 100 tops, adds up to six.Each perforate mechanism 2 just as shown in Figures 2 and 3, have in that be arranged to by bearing 51 on the pedestal 100 can be at Y-axis movable plate 52 that Y direction moves freely and be arranged to the X-axis movable plate 54 that can move freely the left and right directions of Fig. 2 (below, be called " X-direction ") on this Y-axis movable plate by bearing (not shown).
Y-axis movable plate 52 and X-axis movable plate 54 move in Y direction and directions X respectively under the effect of the feed screw 56,57 that is driven by servomotor 53,55 revolutions.That is, servomotor 55 is fixed on the Y-axis movable plate 52, under this servomotor effect, drives feed screw 56 by the coupling revolution.And fixing nut 57 with feed screw 56 threaded engagement on the X-axis movable plate 54, by the revolution of feed screw 56, move towards directions X.In addition, fixing servomotor 53 on the pedestal 100, under the effect of this servomotor, driving feed screw 57 by not shown coupling revolution.And, on Y-axis movable plate 52, fixing the not shown nut with this feed screw 57 threaded engagement, move in the Y direction by the revolution of feed screw 57.
Fixing guiding part 235 on nut 234, this guiding part moves up and down by being arranged on the guide rod 242 slidingtypes guiding on the pedestal 24.And, being arranged on the slotted hole groove on guiding part 235 left ends, by fulcrum pin 236a, can be connected freely to rotate with an end of jack back 236.Jack back 236 is that the center is shaken with gyroaxis 237, and the other end of this jack back can be connected with drift holding components 238 freely to rotate by fulcrum pin 236b.In addition, drift holding components 238 is made at the replaceable drift that is installed with 22 of its front end to move up and down by vertical projections portion 241 guidings that are arranged on the pedestal 24.
In addition, the position that is connected with drift holding components 238 is approached in the position of gyroaxis 237 of supporting jack back 236.Therefore,, strengthened the power of the guiding part 235 that moves up and down by servomotor 231, drift holding components 238 is moved up and down by the principle of lever.In addition, owing to can reduce the distance that the drift holding components 238 of guiding part 235 due to moving up and down moves up and down, control the position that moves up and down of this drift holding components easily more imperceptibly.
Below, the structure that all-in-one-piece image mechanism 4 is set with perforate mechanism 2 is described.Image mechanism 4 shown in Figure 4 is installed on the pedestal 24 with drift holding components 238 with paralleling.Image mechanism 4 is so-called two-dimensional CCD camera, the plate workpiece 1 that is had the hole by perforate mechanism 2 is taken, and sent its shooting results to image processing mechanism 6 (shown in Figure 10).And image mechanism 4 is correctly measured in advance with the relative position of drift 22, even perforate mechanism 2 moves towards the XY direction under the effect of travel mechanism 5, position that also can this image mechanism is a benchmark, can normally correctly calculate the position of this drift.
Below, the effect of this perforate mechanism is described.As an example, use printed circuit board (PCB) 11 shown in Figure 8 with plate workpiece 1, situation about having the pilot hole 11b that determined with the relative position that is formed at the circuit design 11a on this printed circuit board (PCB) describes.In addition, print the identification mark 11c of two circles of the position of opening that is used for definite pilot hole 11b described later on the printed circuit board (PCB) 11.At first, when the perforate operation, as shown in Figure 6 and Figure 7, select corresponding jig plate 362 of position of opening and adsorption plate 363 with printed circuit board (PCB) 11, and these members are installed on the connecting plate 361.At this moment, by servomotor 35, injection mechanism 3 is moved to the input position of left end, if in this position, jig plate 362 and adsorption plate 363 are installed on the connecting plate 361, then other ancillary equipment for example perforate mechanism 2 or image mechanism 4 just can not hinder the dress of jig plate 362 and adsorption plate 363 to take off, can easily adorn and take off jig plate 362 and adsorption plate 363.
Then, as shown in Figure 1,, injection mechanism 3 is moved to the input position of left end, and printed circuit board (PCB) 11 is being kept by anchor clamps 36 absorption in this position by servomotor 35.At this moment, by injection mechanism 3, when putting into printed circuit board (PCB) 11 with perforate described later mechanism 2 opposed positions, two identification mark 11c of this printed circuit board (PCB) are in order to enter in the shooting area that is arranged on two image mechanisms 4 in this perforate mechanism 2, under the state of the relative position of determining anchor clamps 36 and this printed circuit board (PCB), keeping printed circuit board (PCB) 11 by anchor clamps 36 absorption.
That is, the position of opening of opening pilot hole 11b on the printed circuit board (PCB) 11 is calculated with the relative position that is arranged on the center of two datum hole f on the jig plate 362 according to the center of two identification mark 11c that taken by image mechanism 4 described later.Therefore, when putting into printed circuit board (PCB) 11 with perforate mechanism 2 opposed positions, two identification mark 1c must keep with the extraneous mode that can not exceed the shooting area of the image mechanism 4 of standby on the position of regulation, the relative position ground absorption that pre-determines this printed circuit board (PCB) and anchor clamps 36.
As determining that mechanism one example of this printed circuit board (PCB) 11 with the relative position of anchor clamps 36 will illustrate below.That is, as shown in Figure 1, below anchor clamps 36, be provided with printed circuit board (PCB) 11 is set platform 102 is set, this be provided with platform above, be provided with two ccd video cameras (not shown).Ccd video camera is taken two identification mark 11c of printed circuit board (PCB) 11 respectively by the through hole g and the h of jig plate 362, and its center for example makes cross symbol, and shows in monitor picture.In this monitor picture, corresponding with each kind of printed circuit board (PCB) 11, by computer, the shooting area of determining two image mechanisms 4 of position of readiness is made circle represented.Therefore, when watching monitor picture, in the shooting area of representing with circle for the center that enters cross symbol,, just can determine both relative positions by being provided with on the platform 102 with hand mobile printing circuit board 11.
When the printed circuit board (PCB) 11 on platform 102 will be set was arranged at above-mentioned relative position, anchor clamps 36 descended by cylinder 364, and absorption is keeping this printed circuit board (PCB) 11, and these anchor clamps rise by this cylinder once more.Then, arm 35 moves to the 2 opposed positions with perforate mechanism always.When moving to perforate mechanism 2 opposed positions, anchor clamps 36 descend by cylinder 364 always, and the printed circuit board (PCB) 11 that absorption is keeping is arranged on the operation post 101 that is positioned at pedestal 100 tops.In addition, because of anchor clamps 36 pass through spring 365, printed circuit board (PCB) 11 is pressed on the operation post 101, thereby can avoids taking place excessive pushing force and vibrations.
Then, the localization method to the perforate mechanism 2 that has pilot hole 11b on printed circuit board (PCB) 11 describes.This position of opening is determined based on two following basic consideration points.First is, the pilot hole 11b of printed circuit board (PCB) 11 is the benchmark perforate with the center that correctly is formed at two datum hole f among the datum hole f on the jig plate 362.Second is, the circuit design 11a that is printed on the printed circuit board (PCB) 11 is identical with the relative position that designs as far as possible with the relative position of pilot hole 11b.
Two datum hole f that so will be arranged among the datum hole f on the jig plate 362 are benchmark, have the reasons are as follows of pilot hole 11b.Promptly, printing circuit design 11a on the printed circuit board (PCB) 11 although be, with identification mark 11c in the printing of the relative position in the design of relative this circuit design, and consideration has the scheme of pilot hole 11b in the center of this identification mark 11c, but in this scheme, under the situation that the temperature Change of the relative position of identification mark 11c during at printing process or because of perforate staggers, can not on the position that design is determined, offer pilot hole 11b.
As other means, considered on printed circuit board (PCB) 11, be provided with two identification mark 11c, determine with this identification with the perforate coordinate in the design that is labeled as benchmark, on this coordinate, to open the method for pilot hole 11b., in the method, also because of above-mentioned temperature Change etc., under the situation that two identification is staggered with the interval of mark 11c, two identifications are also staggered as the perforate coordinate in the design of benchmark with mark.Therefore, at first, two identifications correctly must be modified to numerical value in the design with the interval of mark 11c.For this reason, on jig plate 362, be provided with as two identifications of datum hole f with corresponding two the datum hole f in interval in the design of mark 11c, and set perforate reference position with this correct at interval identical pilot hole 11b.Then, under the situation that printed circuit board (PCB) 11 is kept by anchor clamps 36 absorption, because of this printed circuit board (PCB) and anchor clamps can misplace at the relative position of XY direction and gyratory directions, the dislocation of relative position that must correction perforate reference position.
At this,, open the operation of pilot hole 11b on the printed circuit board (PCB) 11 and carry out as follows based on above-mentioned consideration.Be pressed to position on the operation post 101 at above-mentioned printed circuit board (PCB) 11, two identifications, enter in the shooting area of two image mechanisms 4 respectively by the through hole g and the h of jig plate 362 with mark 11c.Therefore, 4 pairs of two identifications of camera head are taken with mark 11c, and send its shooting results to image processing mechanism 5.Then, the travel mechanism 5 of camera head 4 distinguishes the relative position with perforate mechanism 2 in advance.Camera head 4 is moved into place on the position of two datum hole f on the jig plate 362, two datum holes are taken, and send its shooting results to image processing mechanism 5.In addition, for two identifications are entered in the shooting area of camera head 4 simultaneously with mark 11c and opposed with it datum hole f, printing this identification on the printed circuit board (PCB) 11 with under the situation of mark, once taking is enough to.
Next, image processing mechanism 5 obtains the XY coordinate of two identifications with the center of mark 11c and two datum hole f according to photographic images, and its result is sent in the calculation mechanism 7.Then, the straight line that calculation mechanism 7 will connect the XY coordinate of center separately compares, and calculates the intersecting angle that both intersect.That is, the degree that staggers of printed circuit board (PCB) 11 and the relative position revolution that is arranged on the datum hole f on the jig plate 362 can only be this intersecting angle.Then, calculation mechanism 7 is obtained the XY coordinate of the centre coordinate (center of gravity) of the straight line that connects each center respectively, calculates the relative position relation of the two centre coordinate (center of gravity).
According to above-mentioned, can obtain the reference position that is used on printed circuit board (PCB) 11, having pilot hole 11b.That is, this reference position is stagger the respectively degree of relative position relation of the two centre coordinate (center of gravity) of centre coordinate with two datum hole f of jig plate 362, and then with the coordinate after the above-mentioned intersecting angle revolution.In other words, this coordinate is two identifications being arranged on the printed circuit board (PCB) 11 to be overlapped and then the center of the datum hole when turning round intersecting angle with the position of centre of gravity of two datum hole f of setting on the position of centre of gravity of mark 11c and the jig plate 362.
; obtaining the method that is used for opening the reference position of pilot hole 11a on printed circuit board (PCB) 11 according to two above-mentioned identifications with mark 11c and two datum hole f, the identification of this reference position is only obtained with a direction (directions X or Y direction) with the relative position relation of mark relevantly relatively.Therefore, when further obtaining both relative position relations accurately, preferably to revise and the dislocation of two identifications with the relative position of the perpendicular direction of mark.Below this method is described.
Printed circuit board (PCB) 11 is provided with the identification in four places mark 11c on every side that is in shown in Figure 9.And, on the jig plate 362, with four identifications with on the suitable position of the allocation position in the design of mark 11c, also be provided with four datum hole f.In addition, four identification with mark 11c be printed on the relative position relation that the circuit design on the printed circuit board (PCB) 11 has regulation.And, image mechanism 4 is taken with mark 11c and datum hole f four identifications respectively by the perforation slotted hole g or the h of jig plate 362, and image processing mechanism 6 is according to its shooting results, obtain center separately, and calculation mechanism 7 is obtained both position of centre of gravitys according to its center.
Then, calculation mechanism 7 moves to the position of centre of gravity of four identifications with mark 11c with the position of centre of gravity of four datum hole f, so that both position of centre of gravitys are consistent.Then, calculation mechanism 7 obtain four limits that constitute by four datum hole f and by four identifications with four limits that mark 11c constitutes, calculate the intersecting angle on corresponding separately four limits, obtain its mean value.More than, distinguish X-direction and the relative position relation these two directions dislocation of Y direction, four identifications usefulness mark 11c of having considered relative four datum hole f.
Promptly, be arranged on four identifications on the printed circuit board (PCB) 11 with four original positions that the position in the design of mark 11c promptly is not subjected to temperature deformation etc., become the position of centre of gravity that makes four datum hole f and four identification and coincide, be the mean value centers when center of gravity is turned round, these four datum holes of the intersecting angle on above-mentioned four limits with the position of centre of gravity of mark 11c.Therefore, as selecting arbitrarily two datum holes from four datum hole f, then the centre coordinate of these two datum holes becomes open two reference positions that pilot hole 11b uses on printed circuit board (PCB) 11.
More than distinguish behind the center of two datum hole f that have two promptly mobile XY coordinates in reference position that pilot hole 11a uses on the printed circuit board (PCB) 11, calculation mechanism 7 is a benchmark with the center of these two datum hole f, is calculated by the center of this datum hole to be in position of opening relative position, pilot hole 11a that design is upward determined.Then, travel mechanism 5 moves to the drift 22 of perforate mechanism 2 on this XY coordinate of calculating.
Below, split holes mechanism 2 operation of perforate on the printed circuit board (PCB) 11 and describe.The drift 22 of perforate mechanism 2 is kept by anchor clamps 36 absorption and is arranged on the operation post 101 up to printed circuit board (PCB) 11, and is positioned at the primary position (with reference to Figure 11) of not interfering these anchor clamps to move.Then, 21 of printed circuit board (PCB) 11 insertion drifts 22 and punch dies are keeping the anchor clamps 36 of printed circuit board (PCB) 11 to be pressed on the operation post 101 absorption.
Then, the servomotor 231 of perforate mechanism 2 makes feed screw 232 revolutions, by jack back 236, drift holding components 241 etc., drift 22 is descended, and this drift is moved to (with reference to Figure 11) on the position of readiness from primary position.This position of readiness is set for, when perforate mechanism 2 moves to the position that has pilot hole 11a, drift 22 not with the height and position of interfering above of the jig plate 362 that is in the anchor clamps 36 on the operation post 101.Therefore, drift 22 can move freely along the XY direction on jig plate 362, simultaneously, can make perforate stroke (drift 22 moves to the distance (with reference to Figure 11) of the position of perforate on printed circuit board (PCB) 11 from position of readiness) minimum, can promptly carry out the perforate operation.
And six perforate mechanisms 2 move to respectively when printed circuit board (PCB) 11 is opened the XY coordinate position of pilot hole 11a by travel mechanism 5, and servomotor 231 revolutions are to leave pilot hole on this printed circuit board (PCB).In addition, on the guiding part 235 that the revolution by servomotor 231 moves up and down, be provided with Fig. 4 and shown in Figure 5, detect the transducer 25 of this guiding part in Z direction position, even thereby this guiding part 235 rises excessively, can be to the excessive power of drift 22 effects yet.
In Fig. 7, as aforementioned, on jig plate 362 and adsorption plate 363, be provided with the yielding hole g of drift 22, the position of opening of the pilot hole 11a of printed circuit board (PCB) 11 is arranged to be in this yielding hole site.In addition, the speed of gyration of the servomotor 231 that drift 22 moves up and down can suitably be changed according to the material of printed circuit board (PCB) 11 or the size of pilot hole 11a etc.For example, Rou Ruan printed circuit board (PCB) 11 relatively, the state that can not produce collapse limit or burr etc. is accelerated punching speed, and relatively more crisp printed circuit board (PCB) or be pasted with the printed circuit board (PCB) of Copper Foil etc. can not produce the slow down punching speed of from the position of readiness to the position of opening (with reference to Figure 11) of the state that breaks or peel off etc.In addition, speed of gyration by control servomotor 231, no matter drift 22 punching speed of (with reference to Figure 11) from the primary position to the position of opening, drift 22 all can high-speed driving from the primary position to the position of readiness and from the position of opening to the primary position, thus, shorten the perforate time, improved operation (with reference to Figure 11).In addition, by the driving of control servomotor 231, the position of readiness of drift 22 is also variable, according to the speed of this drift or the thickness of printed circuit board (PCB) 11 etc., the position of readiness of drift 22 can be set on the only position.In addition, owing to be under servomotor 231 effect, drive drift 22, can adjust the position of readiness of drift 22 micro-ly, be best suited for the perforate of sheet-like workpieces such as printed circuit board (PCB) by feed screw mechanism.
When the perforate of pilot hole 11a finished, drift 22 rose by servomotor 231 and is driven into not primary position (with reference to Figure 11) with the mobile interference of drift 36.And drift 22 stops the attraction of printed circuit board (PCB) 11, and this printed circuit board (PCB) is retained on the operation post 101, drives by cylinder 364 and rises, and absorption is keeping next printed circuit board (PCB), and reverts to original position.When anchor clamps 36 moved to original position, the shift-out mechanism 33 of arm 35 interlocks that are connected with these anchor clamps moved to and stays the printed circuit board (PCB) 11 opposed positions on the operation post 101 together, and by the mechanism same with these anchor clamps, absorption is keeping this printed circuit board (PCB).And when anchor clamps 36 moved to next printed circuit board (PCB) 11 with perforate mechanism 2 opposed positions once more, shift-out mechanism 33 shifted out the printed circuit board (PCB) of perforate process finishing.
In addition, the action of each movable link of above-mentioned boring device promptly move controlling organization 8 (with reference to Figure 10) by belonging to calculation mechanism 7 of beginning or the position of release or time etc., controlled according to the kind of the printed circuit board (PCB) 11 of record in advance.In addition, be provided with the installation site of each member by adjusting fine-tuning as required whole mechanism such as screw rod.Image mechanism 4 is not limited to perforate mechanism 2 the all-in-one-piece occasion is set, and also can be provided with independently.Like this occasion can additionally be provided with image mechanism 4 towards travel mechanism that the XY direction moves.In addition, the moving up and down of drift 22 is not limited to the occasion that driven by servomotor 231, feed screw 232, jack back 236 etc., also can be by drivings such as gear mechanism or rack-and-pinion mechanisms.
In addition, when being arranged on identification on the printed circuit board (PCB) 11 and being hidden in jig plate 362 following with mark 11c, image mechanism 4 also can use X line video camera, obtains its position by perspective.In addition, above-mentioned boring device also can be used as the decision mechanism of the precision confirmation of the position that has had pilot hole 11a etc. on printed circuit board (PCB) 11.
