Fig. 1 a to 1f represents continuing the stage according to the delivery system 10 of first embodiment of the invention.Delivery system 10 is arranged in printed circuit board (PCB) 12a with stacking 12 topmosts of printed circuit board (PCB) (formation workpiece) and is loaded between the loading bin 11 (formation loading attachment) and emptier 15 (formation discharging gear) on the delivery system 10.Delivery system 10 comprises a conveyer 13 and a feed appliance 21.Conveyer 13 is equivalent to main conveying device, and it limits an areal of support, and this areal of support twelve Earthly Branches printed circuit board 12a that undertakes the printing of that is used to advance gave it detection station 14 (constituting a processing unit (plant)) simultaneously.Feed appliance 21 limits an areal of support, and it is used to support printed circuit board (PCB) when the printed circuit board (PCB) of printed circuit board (PCB) being delivered to conveyer 13 and will detect before detection after detection is delivered to emptier 15.Loading bin 11 and emptier 15 generally comprise self-levelling bench board and conveying arm.If desired, the printed circuit board (PCB) that detected can be delivered to another system of processing (not shown) that detects station 14 downstreams from emptier 15, so that further processing.
In the embodiment shown in Fig. 1 a to 1f, main conveyer 13 (constituting second areal of support) is the balladeur train form, and it is suitable for also being suitable for vertical upper and lower motion along guide rail 16 motion of translations, and its reason will be elucidated later herein below.Feed appliance 21 is load-transfer device form (constituting first areal of support), and it has guide wheel 17 and 18 and one the 3rd closed-loop belt 19 that tension wheel 20 supports that detect station 14 upstream and downstream by being arranged on.
In order to determine that a printed circuit board (PCB) on conveyer 13 arrives the time of detecting station 14 and the time of passing through this station fully thereof, pair of sensors 22 and 23 are set, the leading edge that they detect the printed circuit board (PCB) 12a on the conveyer 13 respectively arrives the time of detecting station 14, and the trailing edge of the printed circuit board (PCB) 12a on the conveyer 13 is by the time of this station.
The groundwork step of the flowcharting system 10 of Fig. 2 a and 2b specifically is described in conjunction with each working stage shown in Fig. 1 a to 1f now.Fig. 1 a represents first algorithm, and wherein, the printed circuit board (PCB) 12a of topmost is taken out by loading bin 11 in the stacking of printed circuit board (PCB) 12, and is delivered to the load-transfer device 19 of feed appliance 21 by loading bin 11. Guide wheel 17 and 18 clockwise direction rotate and make load-transfer device 19 runnings, detect station 14 thereby first printed circuit board (PCB) 12a is sent to.In this operating process, first printed circuit board (PCB) 12a on the load-transfer device 19 is vacant now by the zone that loading bin 11 is seen off, thereby can hold the next printed circuit board (PCB) 12b from stacking 12.Therefore, the balladeur train of loading bin 11 returns base (being its initial " loaded " position) now, so that take out second printed circuit board (PCB) 12b from stacking 12, is placed on then on the load-transfer device 19, shown in Fig. 1 b.At this moment, first printed circuit board (PCB) 12a aims at conveyer 13.At this moment, conveyer 13 is raised so that first printed circuit board (PCB) 12a is risen to conveyer 13 from the conveyer 19 of feed appliance 21.For this purpose, on conveyer 13 trailing edges or a sensor 13a is set near it.The trailing edge of printed circuit board (PCB) 12a in sending to is measured when being on the load-transfer device 19 of sensor 13a top, and sensor 13a handles the actuating device (not shown) of conveyer 13, so that make conveyer 13 move into the position of its risings.Therefore, the printed circuit board (PCB) 12a of first topmost is positioned on the conveyer 13 when second printed circuit board (PCB) that continues is contained on the feed appliance 19.
Order is represented each algorithm in Fig. 1 a to 1f.Therefore, in Fig. 1 a, first printed circuit board (PCB) 12a just has been placed on the feed appliance 21, and this moment, the conveyer 13 in first printed circuit board (PCB) 12a downstream was in its low level.
Fig. 1 b represents next algorithm, and this moment, feed appliance 21 made first printed circuit board (PCB) 12a and conveyer 13 overlapping alignment, and the printed circuit board (PCB) 12b that continues is placed on the feed appliance 21 by loading bin 11.When this position, conveyer 13 is raised, so that first printed circuit board (PCB) 12a is sent to the balladeur train that constitutes conveyer 13 from load-transfer device 19.
In Fig. 1 c, still on the end of the feed appliance 21 that detects station 14 upstreams, conveyer 13 then begins to shift to emptier 15 for second printed circuit board (PCB) 12b that continues.In this motion process of conveyer 13, do not apply the interference that can influence testing process to conveyer 13 with the feed appliance 21 that in fact conveyer 13 separates.In this instantiation, from the process of position translation shown in Fig. 1 c, forbid feed appliance 21 motions at conveyer 13, thereby can make first printed circuit board (PCB) finish detection that at this moment, conveyer 13 is back to feed appliance 21 to obtain next printed circuit board (PCB) 12b.If feed appliance forbidden not according to aforesaid way, then next printed circuit board (PCB) 12b can be sent to conveyer 13 and may protrude in the balladeur train collision of the conveyer 13 above the feed appliance 21 with being in its raised position in this stage; Perhaps may be transferred to such an extent that surpass it and pass on to that of the balladeur train of conveyer 13 from the belt of feed appliance 21.For fear of above-mentioned possibility, that aim at sensor 22 from the leading edge of the first printed circuit board (PCB) 12a on conveyer 13 is constantly until the position that the printed circuit board (PCB) 12a shown in Fig. 1 d aims at sensor 23, and feed appliance 21 is forbidden.At this moment, shown in Fig. 1 e, conveyer 13 is lowered, first printed circuit board (PCB) 12a by pine oil on the load-transfer device 19 of feed appliance 21, thereby shown in Fig. 1 f, conveyer 21 is started once more so that first printed circuit board (PCB) 12a is sent to emptier 15, makes second printed circuit board (PCB) 12b that continues be in relation with conveyer 13 overlapping alignment simultaneously.At the upstream extremity of vacant conveyer 21, the 3rd printed circuit board (PCB) 12c that continues adorned to feed appliance 21 by loading bin 11, and whole circulation is repeated.
Fig. 3 represents to limit key feature of the present invention and is the common groundwork steps of various embodiments of the present invention.Therefore, the workpiece that continues is loaded onto on the feed appliance 21, thereby makes workpiece successively be transferred to conveyer.Simultaneously, perhaps after a while, loading bin returns base so that load next workpiece.Feed appliance can not use now, and the workpiece on the conveyer is transferred so that process.After processing, finished workpiece is sent back to the feed appliance that now can work, and repetition is carried out in circulation as required.
Obviously, owing to be provided with the main conveyer 13 of the level of can doing and vertical motion, thereby the loading of the workpiece 12b that continues does not hinder the processing of last workpiece 12a.Equally, the unloading of last workpiece 12a does not influence the processing of the workpiece 12b that continues yet.Each workpiece all is positioned on the conveyer 13 really in the course of processing, and finished workpiece and workpiece to be processed then load on feed appliance 19 respectively or unloading from it.Main conveyer 13 and feed appliance 21 are actually separated.
Consult Fig. 4 now, the figure shows a delivery system 100 according to another embodiment of the present invention body plan.For the purpose of unanimity, parts identical in system 10 and 100 mark identical label.The work of delivery system 100 make continue implement to flow with the fwd printed circuit board (PCB) time printed circuit board (PCB) of one of unlikely interruption in advancing processing.Delivery system 100 between loading bin 11 and emptier 115, and with two processing unit (plant)s, detect station 14 and be arranged on the print stations 114 that detects station 14 downstreams, cooperating.In delivery system 100, be with the previous embodiment difference, be bearing in the main conveying device that detects printed wire down is load-transfer device 121 (constituting first areal of support) form with being used to advance, and feed appliance be balladeur train 113 forms and be used for being sent to conveyer 121 from loading bin 11 receptions printed circuit board (PCB) to be detected and with it.Also be provided with a discharge conveyer 24, it is used for discharging the printed circuit board (PCB) that detected and it being delivered to print stations 114 from main conveyer 121.Discharge conveyer 24 is load-transfer devices, and its structure and work will be described hereinafter specially.
Detecting station 14 adopts multiple conventional art with the detection crackle that printed circuit board (PCB) is carried out traditional detection.Itself do not constitute a part of the present invention owing to detect station 14, thereby here its structure and work are repeated no more, but be noted that printed circuit board (PCB) is to be detected from the top by suitable optical unit, described optical unit is suitable for scanning printed circuit board (PCB) so that find defective.For example, can adopt the CCD image sensor LKI-6003 that can buy from Eastman Kodak company.Print stations 114 is used to mark the detected crack position that may exist.Should be noted in the discussion above that print stations 114 can select to be provided with, so that the most general situation of casehistory processing work on an above station.
Loading bin 11 can be any known kind, for example can be from Rescotron, and the PCB Car.Automat MA 6095067 that Italy has bought.Therefore, get up and by automatic leveling supply table 11a supporting etc. printed circuit board stacking to be detected, this supply table comprises an automatic lifting mechanism, and it is used for promoting continuously the height of stacking so that the printed circuit board (PCB) of topmost is remained on predetermined vertical position.Also be provided with one and load balladeur train 11b, it have a plurality of be used for from stacking 12 catch topmost printed circuit board (PCB) 12a suction cup 11c and be conditioned so that between supply table 11a and balladeur train 113 (formation feed appliance), slide along a slide rail 11d.Obviously, loading bin 11 also can be another kind of structure, for example, can comprise additional feedway, and it is suitable for receiving the printed circuit board (PCB) 12a of topmost and it being transferred to another feedway from supply table 11a.
Load-transfer device 121 between loading bin 11 and print stations 114, extend and be suitable for towards with transport printed circuit board (PCB) by detecting station 14.As more specifically representing among Fig. 5 a, conveyer 121 has the bogie side frame 26 and 27 of a pair of supporting wheel 17 and 18 liang of opposite ends, and each is with determining deviation back(-)up belt wheel 30, and it is used for supporting belt 32.Load-transfer device 32 can be the round belt PN DLA-7 (GREEN) that can buy from the MULON Co., Ltd.Load-transfer device 32 is subjected to a cylinder 34 (the constituting second areal of support) supporting of position therebetween under tension force.Cylinder 34 itself is bearing among relative the bogie side frame 36a and 36b, and above-mentioned bogie side frame is independent of the bogie side frame 26 and 27 of conveyer 121.The outside face of cylinder 34 is formed with a plurality of circumferential recess spaced apart 38, accommodates relevant load-transfer device 32 in these grooves slidably.By said apparatus, cylinder 34 not only sent detection station 14 with printed circuit board (PCB) 12a, and was bearing in areal of support in the detection zone as the part in succession with each printed circuit board (PCB) 12a.The outside face of cylinder 34 preferably is provided with a thin rubber coating so that increase the areal of support of cylinder 34 and the friction between the printed circuit board (PCB), thereby prevents that the improper of printed circuit board (PCB) 12a moved in testing process.

Each printed circuit board (PCB) in the obvious stacking 12 as can be seen sent by load-transfer device 32 and detected station 14.As mentioned above, a principal character of the present invention is that the printed circuit board (PCB) that continues is placed on the main conveyer 121 (being 13 in precedent), and the mode of placement is unlikely to be caused the variation of conveyer 121 or its any other hindered the interference of optical detection precision.
Fig. 6 a is the scheme drawing of feed appliance 113, and it is worked with conveyer 121, so that make the printed circuit board (PCB) that continues transfer to conveyer 121 ideally from loading bin 11.Therefore, it should be noted that feed appliance 113 has an areal of support 60, its form is a turntable 61 spaced apart, and these turntables are arranged between the adjacent load-transfer device 32.When feed appliance 113 is in elevated position (shown in Fig. 6 a), the areal of support that is formed by the upper surface of turntable 61 is higher than load-transfer device 32.Feed appliance 113 is by 63 ascending, descendings of mechanical linkages mechanism, and this link mechanism has upper and lower control position, is illustrated respectively among Fig. 6 b and the 6c.
Therefore, link mechanism 63 comprises the link rod 64 and 65 of pair of parallel, and they are hinged on relevant pivot 66 and 67, and on its opposite ends, they are installed in the bogie side frame 26 and 27 of conveyer 121.Link rod 64 and 65 upper end are articulated in the upper surface 60 of feed appliance 113, link rod 64 and 65 lower end then are articulated in depression bar 68, this depression bar itself is connected in piston 69, and this piston is used for making depression bar 68 to do moving back and forth of level, so that the areal of support 60 of ascending, descending feed appliance 113 as required.Specifically, shown in Fig. 6 a and 6b, when feed appliance 113 is in it when high-order, turntable 61 is outstanding by the gap between the conveyor belt 32, and it is when being in low level, and shown in Fig. 6 c, the areal of support 60 of feed appliance 113 is positioned under the load-transfer device 32.Though specifically do not draw, obviously printed circuit board (PCB) is to be on its areal of support 60 that at first printed circuit board (PCB) is placed on feed appliance 113 when high-order and to transfer on the conveyer 121 from loading bin 11 at feed appliance 113; Thereby feed appliance makes the printed circuit board (PCB) on feed appliance 113 areal of supports 60 be transferred to the load-transfer device 32 of conveyer 121 when the position reduced to shown in Fig. 6 c.
When this system is used for the optical detection of printed circuit board (PCB), successively carry out optical detection and stamped mark two different stages usually.As everybody knows, at the F/s of optical detection, finding on the printed circuit board (PCB) or suspecting that defective position is remembered and in the printing stage thereafter, each above-mentioned position is marked, so that can make hand inspection, as may then being revised thereafter.Therefore, the most important thing is that optical detection station 14 and print stations 114 will correctly be aimed at.In the practice, both aim at and realize by guaranteeing to make printed circuit board (PCB) itself and detection station 14 and print stations 114 for this.This aligning is to pass through to detect station 14 by control printed circuit board, makes its guide lug be parallel to the scanning line that detects station 14 and the lateral margin maintenance is flushed with the inside face of bogie side frame 26 to realize.Above-mentioned to finishing by hand or automatically.
For this purpose, feed appliance 113 is provided with an alignment device, and it limits two aligning shoulders that are mutually the right angle, and it can contact with the aligning bight of printed circuit board (PCB), accurately locatees so that be processing.Shown in Fig. 6 a, alignment pin 70 is arranged on the downstream end of feed appliance 113, thereby the operator can be loaded into printed circuit board (PCB) on the feed appliance 113 by hand, and feed appliance is in a high position, and the guide lug of printed circuit board (PCB) contacts with the inside face of alignment pin 70 with bogie side frame 26 respectively with lateral margin.
Fig. 7 a and 7b schematically represent the end elevation of another kind of feed appliance 213 (constituting the 3rd areal of support), and wherein, it is to implement automatically that the needs of printed circuit board (PCB) 55 are aimed at.As shown in the figure, the turntable 61 of previous examples is substituted by a plurality of guide wheels spaced apart 76 that are placed between the conveyor belt 32 here, and guide wheel 76 defines an areal of support 75.Guide wheel 76 is installed on the axle 77, and the two ends of axle 77 are contained on the support 78, is handled so that ascending, descending is to the position shown in Fig. 7 a and the 7b respectively by suitable mechanism's (not shown).Therefore, at work, guide wheel 76 at first rises to position shown in Fig. 7 a, and the areal of support 75 of feed appliance 213 that wherein constitutes the upper surface of each guide wheel 76 shows out the upper surface of load-transfer device 43 especially.Then, printed circuit board (PCB) 55 pine oils as implied above are on feed appliance 213, and guide wheel 76 (as shown in the figure) clockwise direction rotates, thereby laterally printed circuit board (PCB) 55 is sent to bogie side frame 26.After this is finished, support 78 is reduced to position shown in Fig. 7 b, wherein, the areal of support 75 of feed appliance 213 is under the areal of support of load-transfer device 32.Means transfer to conveyer 121 with printed circuit board (PCB) 55 from feed appliance 213 whereby.
Consult Fig. 4 now, discharge conveyer 24 is band conveyors, and it comprises load-transfer device 80, and load-transfer device 80 is supported by guide wheel 80a and 80b at its two ends.Discharge conveyer is used for banking motion, but thereby the guide wheel 80a lifting of its upstream must be higher than the height of conveyer 121.By such means, the printed circuit board (PCB) on the conveyer 121 can transfer to emptier 24, so that implement and the separating of load-transfer device 32, this will specifically consult Fig. 8 f and describe.
A pin 88 is bearing on the bogie side frame 87, and this is sold perpendicular to throughput direction D
1Place, and rotatably support is a plurality of takes turns 89, these are taken turns the parallel relation that comes with the space along the length of pin and install.As shown in the figure, wheel 89 process calibrations, parallel and a little higher than guide wheel 85, so that the printed circuit board (PCB) during clamping is advanced betwixt, and guide it to slide to emptier 115.
Shown in Fig. 8 b, this moment, feed appliance 213 was lowered, thereby its upper surface is under the upper surface of conveyer 121, thereby first printed circuit board (PCB) 12a is transferred to conveyer 121 from feed appliance 213.In this operating process, loading bin 11 returns base so that load second printed circuit board (PCB) 12b that continues.Printed circuit board (PCB) 12b aims at conveyer 121 in advance, the correct aligning of its maintenance in the time of simultaneously still on feed appliance 213, thereby when being placed in conveyer 121 on.Need not on conveyer 121, to aim in addition by such means as printed circuit board (PCB) 12a.
Shown in Fig. 8 c, this moment, conveyer 121 was driven by cylinder 34, so that printed circuit board (PCB) 12a is sent to detection station 14 till the guide lug of printed circuit board (PCB) 12a arrives first sensor 22.
Shown in Fig. 8 d, the further rotation of cylinder 34 and the motion of conveyer 121 were sent detection station 14 with first printed circuit board (PCB) 12a, when doing like this, made feed appliance 213 vacant.Vacant feed appliance 213 now is raised so that receive second printed circuit board (PCB) 12b in succession, and in during this period of time, conveyer 121 preferably can not be worked, thereby the unlikely interference of the motion of feed appliance 213 is just by detecting the printed circuit board (PCB) 12a of station 14.
Shown in Fig. 8 e, cylinder 34 rotations this moment are finished thereby indication detects so that sent detection station 14 to arrive sensor 23 until the trailing edge of printed circuit board (PCB) 12a first printed circuit board (PCB) 12a along conveyer 121.Relation between the distance between the upstream guide wheel 80a of the length of printed circuit board (PCB) 12a and cylinder 34 and discharge conveyer 24 makes the overlapping at least slightly upstream of the leading edge guide wheel 80a of printed circuit board (PCB) 12a.Feed appliance 213 is lowered now, second printed circuit board (PCB) 12b that continues is passed on to conveyer 121, so that sent detection station 14.
Shown in Fig. 8 f, second printed circuit board (PCB) 12b that continues sent detection station 14, and this leading edge that continues to carry out until second printed circuit board (PCB) 12b arrives sensor 22.Obviously, the printed circuit board (PCB) 12a fortune that conveyer 121 will detect when printed circuit board (PCB) 12b being sent to detection station 14 is to print stations 114.Near the sensor 24a that is provided with the guide wheel 80a of conveyer 24 detects the completing place of printed circuit board (PCB) 12a on conveyer 24.Conveyer 121 can not be worked now, thereby second printed circuit board (PCB) 12b that continues is still static, the upstream guide wheel 80a of discharge conveyer 24 is tilted, thereby the further rotation of load-transfer device 80 makes first printed circuit board (PCB) 12a unloaded, because conveyer 24 and 121 is actually separately, thereby the load-transfer device 32 of unlikely interference conveyer 121.
Shown in Fig. 8 g, when the unloaded just like this conveyer 24 of first printed circuit board (PCB) 12a unloaded, cylinder 34 started once more, and conveyer can be worked, thereby sent detection station 14 to leave feed appliance 213 until its trailing edge the second printed circuit board (PCB) 12b, this is shown by sensor 37.This moment, feed appliance 213 was raised so that accept the 3rd printed circuit board (PCB) 12c. that continues from loading bin 11
At last, shown in Fig. 8 h, feed appliance 213 is lowered, so that the 3rd printed circuit board (PCB) 12c that continues is sent to conveyer 121; The upstream guide wheel 80a of discharge conveyer 24 is reduced to its normal control position, and cylinder 34 is driven so that conveyer 121 can be worked.Conveyer 121 is sent to print stations 114 with first printed circuit board (PCB) 12a now, and simultaneously, second printed circuit board (PCB) 12b sent 14, the three printed circuit board (PCB) 12c of detection station partly to be sent to and detect station 14.
Consult the Figure 10 that more specifically represents load transfer device 92 now.Equipment 92 comprises a bearing assembly 101 and a support 102.Bearing assembly 101 is installed on the top part 102a of support 102.Shown in Figure 14 a to 14f, the upper surface of a little higher than collection platform 90 of part 102a, and perpendicular to throughput direction D
1Extend.Obviously, the upper surface of platform 90 is surfaces that upper surface limited by the printed circuit board (PCB) that is collected of topmost in " loading " state.The opposite end of top part 102a is by a pair of along throughput direction D
1The guide rail 103 (Fig. 4) that extends is contained on the sidewall 102b slidably.Obviously also can adopt any other proper device make part 102a along the upper surface of collecting platform 90 towards and away from wheel 89 crank motions.A kind of traditional motor, for example a belt drive slides part 102a.A sensor 104 suitably is set, for example it is arranged on pin 88 arbitrary ends near, its purposes will describe in detail hereinafter.Sensor 104 is optical pickocff preferably, as the WE-R3BL that can buy from Highly Electric company.
According to this example, bearing assembly 101 designs to such an extent that resemble a clamper, and it comprises three couples of clamp jaw 105a-105b, and they are installed on the holder part 102a with parallel relation spaced apart along its length.It should be noted that in general, it is just enough that a pair of such clamp jaw is set at least, but preferably use many to clamp jaw so that on the whole width of the workpiece of various sizes, keep basic tension force uniformly.
Parallel identical tabular brake component 106 also is housed on part 102a, each two adjacent clamp jaw 105a-105b between.Plate 106 is formed with the outside face of the leading edge of the printed circuit board (PCB) (not shown) of flat substantially front surface 106a in advancing with joint.Plate 106 can be selected to be provided with, and its purpose prevents just that printed circuit board (PCB) is undesirable and advance that this will be described below.Surface 106a is as workpiece motion s position hill holder, and it guarantees that workpiece is hunted down in its " edge " pattern-free zone.
Upper and lower pawl 105a and 105b are installed in respectively on pin 107a and the 107b.In this example, pawl designs to such an extent that resemble rubber roll.Among roller 105a and the 105b at least one, preferably upper roller 105b is contained on the pin 107b rotationally.Pin 107a and 107b are driven that (Figure 11 a) and open between (Figure 11 b) position on the contrary and swing in opposite directions, this carries out in the following manner in its closure so that resemble the shearing.
Consult Figure 12 a to 12b now, as shown in the figure, the liter of pawl, close in the following manner and carry out.The identical link rod assembly 108 rest pin 107a of two symmetries and the opposite ends of 107b.Link rod assembly 108 comprises a pair of link rod 109 and 110, and they interconnect by axis 111.Dihedral link rod 109 is in the end of one end bearing lower pin 107a, and link rod 110 is in the end of one end bearing upper pin 107b.Link rod 109 and 110 free end are connected in part 102a by a pair of spring 112a and 112b respectively.
Push rod member 117 is installed on the axle 116 in the following manner rigidly, that is, and and each member 117 and corresponding link rod 109 cooperatings.Push rod member 117 engages corresponding link rod 109 when rotating with axle 117.
A pin 118 is housed in that support 102 is above-mentioned, this pin rotatably support is a plurality of takes turns 119, and these are taken turns according to contrasting with link rod 110 parallel relation similarly spaced apart.Each takes turns the 119 swing guiding for a corresponding link rod 110.For this purpose, link rod 110 is formed with wedge-shaped edge part 110a, can be along the circumferential slippage of wheel 119 when link rod 110 swings.
Therefore, pawl 105a and 105b remain on its common make position by the compression of spring 112a and 112b, limit a vertical plane P.Obviously, when ordering about the rotation of axle 116 (anticlockwise directions in Figure 12 a and 12b), the pulling force of the rotation resistance spring 112a of push rod member 117 applies certain power to link rod 109.This makes link rod 109 around axle 116 swings.As for link rod 110, the swing that they revolt the pulling force of spring 112b is driven and guiding by track adjusting wheel 119.As Figure 12 b clearly represented, wheel 119 limited the swing of link rods 110, thereby defined the maximum opening of pawl 105b.The structure of link rod assembly 108 can make the aperture that pawl 105a and 105b form betwixt is enough to admit printed circuit board (PCB).
Obviously because the pivot center of link rod 109 (axle 116) is from its top displacement, thereby axle 116 just can form pawl 106 from vertical plane V displacement greatly backward relative to less rotating.In addition, also can further increase the aperture of pawl 105a by the swing of restriction pawl 105b.These features are for unclamping workpiece from clamp jaw, and to make the workpiece in advancing can be particular importances near the surperficial 106a of slipper 106.
Figure 13 a to 13c represents to order about the piston apparatus 120 that axle 116 rotates.Piston apparatus 120 can be any known kind, for example the cylinder double acting G-7-X-PM-RC-12 that can buy from U.S. Fabco company.Piston apparatus 120 is installed on the support 102 swingably by link rod 122.The member 123 that moves back and forth of piston apparatus 120 is connected in axle 116 by a link rod 124 (or a plurality of suitable interconnective bar) with L-shaped substantially part 124a.Link rod 124 is contained on the axle 116, is pivotably connected in moving back and forth member 123.Obviously, piston apparatus 120 is connected to the motion of device 120 in the plane of movement of link rod 124 with respect to the swing of support 102 degree of freedom is provided.
For the position of control part 124a is provided with a suitable sensing device 126, as the Phto Interrupter TLP 1201-C1 that can buy from Toshiba.The position of part 124a is the indication of clamp jaw 105a-105b position.Sensing device is connected in a control unit, and it is used to make the work of load transfer device 92 to keep synchronously, and this control unit does not specifically draw.
Now specifically consult the work that Figure 14 a to 14f describes load transfer device 92.Figure 14 a represents that chucking device 92 is in its utmost point " left side " position at first, near guide wheel 85-89.The printed circuit board (PCB) 12a that detected shifts to emptier 115 on conveyer 81.Therefore, conveyer 81 defines a supply areal of support, so that supporting prepares to transfer to the printed circuit board (PCB) 12a that collects platform 90 with advancing.It should be noted that in this example, emptier 115 then print stations 114 is provided with.Therefore, chucking device 92 transports the workpiece that arrives from print stations.Perhaps, though do not draw, emptier also can with main conveyer 121 cooperatings, in this case, pin 88 will be installed on the bogie side frame 27, wheel to 18-89 as track adjusting wheel.
When the leading edge of the printed circuit board (PCB) 12a that is led by wheel 85-89 arrived the visual field of optical pickocff 104, optical pickocff 104 driven plunger devices 120 were so that open pawl 105a-105b.Obviously, piston apparatus 120 is to be activated immediately behind the position that detects printed circuit board (PCB) 12a, perhaps have a time lag with respect to the position of the back guide wheel 85 of conveyer 81 according to sensor 104, thereby at the leading edge trailing wheel 85-89 of printed circuit board (PCB) 12a then and the moment of coming makes chucking device 92 be in the position that it prepares clamping.
When between pawl 105a that the leading edge of printed circuit board (PCB) 12a is being opened and the 105b, conveyer 81 preferably stops, so that make the printed circuit board (PCB) 12a can be along its width by successfully clamping of pawl 105a-105b.For this purpose, the actuating device (not shown) of conveyer 81 depends on the circumstances, and suitably is connected in control unit or additional control setup.Should be noted in the discussion above that in failure situations slipper 106 stops the motion of advancing of printed circuit board (PCB) 12a to prevent that its area of the pattern is damaged.
In this stage, though specifically do not draw, control unit actuating plunger device 120 is so that closed clamp jaw 105a and 105b.When clamping, the rotation of upper jaw 105b can be avoided undesirable friction between printed circuit board (PCB) 12a and the pawl.
When the position of the part 124a that detects link rod 124, control unit starts the driving device of support 102, so that make support deviate from conveyer 81 along guide rail 103, moves towards " right side " position of the part 102a of figure median claw.As clearly illustrating among Figure 14 d, relative two edges of printed circuit board (PCB) 12a are respectively by clamp jaw 105a-105b and guide wheel 85-89 supporting.As long as make the sliding velocity of support 16 meet the velocity of rotation of load-transfer device 82, guide wheel 85-89 just can provide the printed circuit board (PCB) in advancing needed high tension.It should be noted that being provided with of guide wheel 85-89 helps advancing of flexible workpiece, and can prevent that it and following workpiece (in the stacking of collecting one of topmost) are damaged.
When whole printed circuit board (PCB) 12a located to such an extent that be higher than the upper surface of collecting platform 90, the slip of support 102 stopped, and pawl 105a and 105b put once more to its open position (not shown), so that unclamp printed circuit board (PCB) 12a.The additional slip that support 102 preferably is provided in the pawl opening procedure is to avoid the possible delay of printed circuit board (PCB).Thereafter, pawl is put to its make position (Figure 14 e), and support 102 slips into its initial position.Shown in Figure 14 f, chucking device 101 is in it once more and prepares clamp position, so that next printed circuit board (PCB) 12b is sent to another by collecting the static areal of support that platform 90 limits from an areal of support that moves that is limited by conveyer 81.
It should be noted that according to above-mentioned example, support 102 is mounted in to be collected on the platform 90.In other words, load transfer device 92 is component parts of emptier 115.
Perhaps, though do not draw, also can one the independent unit of installing of load transfer device, it seals areal of support between bogie side frame.This load transfer device 192 schematically is illustrated among Figure 15.For the ease of understanding, parts identical in equipment 92 and 192 use identical label.Load transfer device 192 comprises the bearing assembly 101 on the part 102a that is installed in support 102 of a support 102 and a chucking device form.Here, different with equipment 92 is, a bogie side frame 102c is provided with also and is formed with pair of guide rails 103, and it is used for the sidewall 102b of supporting bracket 102 slidably.Bogie side frame 102c extends downwards, preferably is installed on the wheel 125.This makes load transfer device 192 deliver to another station satisfying the needs of particular application from a station, unloads workpiece and is located on the areal of support of relevant station from a supply conveyer.
Though do not draw, load transfer device 192 preferably is provided with a lift system so that regulate the vertical position of the bearing part 102a of pawl as required.In addition, the distance between the sidewall 102b can be according to the size adjustment of areal of support.For this purpose, the bearing part 102a of pawl, and the axle 116 and pin 118 can partly constitute by two telescopic bonded assemblys.
In above-mentioned each example, bearing assembly 101 designs to such an extent that resemble a chucking device, and it meets the needs that conveying is flexible workpiece substantially.Figure 16 represents a load transfer device 292 according to another example body plan of the present invention.Equipment 292 is similar substantially with 192 to equipment 92, but the structure of bearing assembly 201 is slightly different, and it is suitable for supporting the workpiece of base quantity rigidity.Bearing assembly 201 is installed on the support 202, and this support is similar to support 102, comprises part 202a and pair of sidewalls 202b above one, and they are installed on the pair of guide rails of making on the bogie side frame 202c 103.Bearing assembly 292 is by a pair of spaced apart, and the parallel long and narrow supporting member 205a and the 205b that extend perpendicular to throughput direction D constitute.Supporting member 205a and 205b are preferably with rubber coating.According to this example, member 205a and 205b are installed in respectively in a pair of elongated slot of making on the 202b of two side 203, and are driven by the appropriate driving device (not shown), so that reciprocating along recess axis.Braking element 206 can be set like this, and they have the outside face of the front portion of the workpiece of flat substantially front surface 206a in advancing with joint.
Obviously, when come from guide wheel 85-89 advance the front portion of printed circuit board (PCB) will be bearing on supporting member 205a and the 205b, be arranged on the upper surface of collecting platform 92 for the pine oil workpiece and with it, supporting member 205a and 205b are activated so that slide along throughput direction in groove 203.Perhaps, though do not draw, each supporting member 205a and 205b also can install to such an extent that be suitable for being wound with and close sidewall 202b and do suitable swing.
What should be specifically noted that is that supporting member all can be selected to adopt with respect to any motion of rack side wall.As the description of being done in conjunction with load transfer device 12, the pine oil of workpiece can carry out in the following manner, that is, one after the other stop and establishing whole bearing assembly 201 along throughput direction D again
1Slip.Stopping and establishing again of sliding is to detect the enforcement when supporting with advancing and being positioned at fully above the areal of support that is limited by collection platform 90 of areal of support that printed circuit board (PCB) no longer limits by conveyer 81.
It should be noted that supporting member 205a and 205b can be substituted by single supporting member, these single supporting member two opposite ends are installed on the sidewall 202b.Perhaps, the top part 202a that also one or more tabular supporting members can be installed in support 202 goes up so that make its orientation be basically parallel to the upper surface of collecting platform 90.
Advantage of the present invention is self-explantory.In fact the setting of feed appliance 213 separates with main conveying device 121 on the one hand, is mated work on the other hand again as required, therefore brings following advantage:
1) printed circuit board (PCB) location to be processed is accurate;
2) pinpoint printed circuit board (PCB) can be transferred to main conveying device;
3) location of printed circuit board (PCB) to be processed and processing and the processing unloading of printed circuit board (PCB) afterwards of not disturbing last printed circuit board (PCB) of passing on.
Owing to be provided with cylinder 34, it as the driving drum of whole feedway 121, is made the supporting station of station 14 on the other hand, thereby has significantly simplified the structure of whole delivery system 100 on the one hand.In addition, the problem relevant with focus that is set to always to exist in the optical detective technology of eccentric driving device 40 provides a kind of effective, simple solution.
