As shown in Figure 1, transport platform 2 rotates by not shown driver train as described above, in the outside of transport platform 2, undertaken vibrating by not shown vibrating mechanism and become by workpiece the linear loader 6 of a column-shaped state conveying to be horizontally disposed with towards the purliew of transport platform 2.The terminal part of linear loader 6 is relative with the peristome of workpiece reception hole 3, is provided with above-mentioned separation supply unit 7 at the terminal part of linear loader 6, utilizes this separation supply unit 7 to be separated one by one by workpiece, to supply to workpiece reception hole 3.In addition, the 1st inspection portion 8, the 2nd inspection portion 9, discharge portion 10 is provided with at the peripheral part of transport platform 2 successively along intermittent rotary direction (arrow A).
As mentioned above, be fed device lid 6x and cover above linear loader 6, the lid 7x of the portion of being supplied to above being separated supply unit 7 covers, and is covered above workpiece reception hole 3 by platform lid 5.Therefore, can not directly see workpiece W from top side, but in figure 3, shade line be marked to the workpiece W in linear loader 6 and workpiece reception hole 3, represents as transparent view.
Then workpiece W is described.Fig. 2 represents the block diagram of workpiece W.Workpiece W is made up of light-emitting diode (LED), has: have above the rectangular shape of emitting surface Ws main body Wx and from main body Wx to the front of length direction and outstanding lead terminal Wa, the Wb in rear.
Such as, when workpiece W is positioned at linear loader 6, the leading flank Wd of lead terminal Wb autonomous agent Wx gives prominence to, the bottom surface of lead terminal Wb is consistent with the bottom surface of main body Wx, and the trailing flank Wc of lead terminal Wa autonomous agent Wx gives prominence to, and the bottom surface of lead terminal Wa is consistent with the bottom surface of main body Wx.
Lead terminal Wa and Wb is electrode, and detector described later (probe) Pa and Pb abuts with lead terminal Wa and Wb respectively, measures the electrical characteristics of workpiece W.
As the example of the LED that market is sold, have that longitudinal X of main body Wx is 3mm, horizontal Y is 5mm, height Z is 1mm, the length j of the protrusion of lead terminal Wa and Wb is 0.3mm, height k is the LED of 0.25mm.As shown in Figure 4, above-mentioned workpiece W, makes emitting surface Ws carry towards length direction in the direction of arrow B in linear loader 6 upward.
In fig. 8, at the part mark shade line that workpiece W passes through.In linear loader 6, ground (bed surface) 6a of linear loader vertically vibrates under the effect of not shown vibrating mechanism, conveying workpieces W.The ground on the ground and workpiece reception hole 3 that are positioned at the separation supply unit 7 of the terminal part of linear loader 6 all becomes above pedestal 1.
As shown in Figure 7, being above fed device lid 6x and covering of linear loader 6.In addition, the ground 6a of linear loader 6 becomes above loader seat 6y, and this loader seat 6y, under the effect of not shown vibrating mechanism, vertically vibrates as arrow V.And as mentioned above, be positioned at the separation supply unit 7 of the terminal part of linear loader 6 above and the lid 7x of the portion of being supplied to above of workpiece reception hole 3 cover.In addition, the separation ground of supply unit 7 and the ground of workpiece reception hole 3 all become the 1a above of pedestal 1, at separation supply unit 7, are provided with the separate pins 12 of vertically freely retreating in (closest) part that is close to of the workpiece reception hole 3 of pedestal 1.
Separate pins 12 is under the effect of not shown driver train, retreats in the direction along arrow D and E.The central side close to transport platform 2 the pedestal 1 becoming the ground of workpiece reception hole 3 and above supply unit lid 7x be provided with workpiece sensing portion 13a and 13b.
13a never graphic light source in workpiece reception hole 3 in workpiece sensing portion sends light, and workpiece sensing portion 13b detects this light.Thus, detect whether be accommodated with workpiece W in workpiece reception hole 3.
In addition, at separation supply unit 7, the pedestal 1 below transport platform 2 is provided with the vacuum passage 11 be communicated with not shown vacuum source.Vacuum passage 11 is communicated with via the suction hole 11a of transport platform 2 with the wall being located at workpiece reception hole 3, the workpiece W in workpiece reception hole 3 under the effect of vacuum source by the direction attracting holding to arrow C.
Then, Fig. 6 (a), (b) represent the block diagram of workpiece reception hole 3.Fig. 6 (a) is the figure representing the state of not receiving workpiece W, at workpiece reception hole 3 when being separated supply unit 7 and stopping, carrying out vacuum attraction from suction hole 11a to the direction of arrow C.Fig. 6 (b) represents the figure being accommodated with the state of workpiece W at separation supply unit 7.Workpiece W is by the direction that makes its length direction and lead terminal Wb the give prominence to center position ground vacuum attraction towards transport platform 2.
Fig. 5 represents the appearance of conveying workpieces W in loader 6.Workpiece W with lead terminal Wa and Wb the mode of downside be one row be configured in linear loader ground 6a, by the arrow V direction of loader seat 6y vibration and carried by the direction to arrow B.
Now, due to the vibration in arrow V direction, workpiece W from 6a above loader seat 6y below loader lid 6x 6b jump, be therefore set as adding the maximum height of jump and the slightly large value h of the value that obtains than the height Z of workpiece from the overhead height of the ground of linear loader (loader seat 6y above 6a) loader lid 6x to 6b below loader lid 6x
1.
In order to accelerate the delivery speed of workpiece W, need the amplitude increasing vibration, if the amplitude of vibration becomes large, then the maximum height that workpiece jumps becomes large.Therefore, along with delivery speed accelerates, the overhead height h of loader lid 6x
1uprise.As an example, be accommodated in workpiece reception hole 3, the overhead height h of loader lid 6x to carry the workpiece W of height Z=1mm in Fig. 2 with the speed of per minute 900
1for 1.4mm.
In the figure 7, pedestal 1 does not vibrate, but workpiece W to jump due to the vibration of loader seat 6y to be moved to from linear loader 6 and is separated supply unit 7.Therefore, 7a below supply unit lid 7x
1be positioned at loader lid 6x below in 6b same level.
On the other hand, the thickness of transport platform 2 and the height u of workpiece reception hole 3 are values slightly larger than the height Z of the workpiece W in Fig. 2.As an example, the height u receiving the workpiece reception hole 3 of the workpiece W of above-mentioned height Z=1mm is 1.1mm.At this, supply unit lid 7x covers the 2a above of a part for transport platform 2, but owing to needing the leakage of the vacuum attraction of doing one's utmost the workpiece W of inhibit function in workpiece reception hole 3,7a below supply unit lid 7x
2be set as minimum with the gap of the 2a above of transport platform 2.As an example, during height (thickness of the transport platform 2) u=1.1mm of above-mentioned workpiece reception hole 3,7a below 1a above pedestal 1 to supply unit lid 7x
2overhead height h
2for 1.2mm.That is, 7a below supply unit lid 7x
1with 7a
2between have step difference.
As mentioned above, be separated supply unit 7 and be positioned at workpiece reception hole 3 portion of the being supplied to lid 7x being separated supply unit 7 and cover.In addition, being covered by platform lid 5 above of the transport platform 2 containing the workpiece reception hole 3 be separated beyond supply unit 7, below platform lid 5 5a be positioned at supply unit lid 7x minimum below 7a
2in same level.That is, below from 1a above pedestal 1 to platform lid 5, the overhead height of 5a is h
2.
At this, the overhead height of loader lid 6x refers to the height of 6b below 6a to loader lid 6x above loader seat 6y as described above, and the overhead height of supply unit lid 7x to refer to above pedestal 1 7a below 1a to supply unit lid 7x
1height, the overhead height of platform lid 5 refers to the height of 5a below 1a to platform lid 5 above pedestal 1.
In addition, as shown in Fig. 9 ~ Figure 14, the part adjacent with supply unit lid 7x in platform lid 5 is provided with and forms bevelled inclined plane part 5b at platform lid 5 inner face.Now, the overhead height of platform lid 5 is at this inclined plane part 5b place step-down gradually.

1the state abutted is incorporated in (with reference to Figure 35) in workpiece reception hole 3.In such a state, from the state of Figure 10, by the effect of control part, transport platform 2 starts the direction intermittent rotary to arrow A, then become the state of Figure 11.Transport platform 2 continues to rotate further in this condition, then as shown in figure 12, workpiece W2 moves to the below of platform lid 5.Now, owing to being provided with inclined plane part 5b at platform lid 5, and as mentioned above, the height of the position adjacent with supply unit lid 7x and the inclined-plane starting point P of inclined plane part 5b is 7a below supply unit lid 7x
1above, the top W of the therefore trailing flank Wc of workpiece W2
lalong with the rotation of transport platform 2 from 7a below supply unit lid 7x
1mobile upper to inclined plane part 5b swimmingly, become the state abutted with inclined plane part 5b.
Then, by the effect of inclined plane part 5b, the top W of the trailing flank Wc of workpiece W2
las shown in Figure 13, it is step-down highly gradually, arrives the inclined-plane terminal Q of inclined plane part 5.Thereafter as shown in Figure 14, do not having below the platform lid 5 of inclined plane part 5b, workpiece W2 becomes the state of being received by level, and the posture of workpiece W2 is revised.Now, to move to the state below platform lid 5 from the below of supply unit lid 7x at workpiece W2 as shown in figure 12, workpiece W2 leaves from the suction hole 11a shown in Fig. 7, and the power that therefore pull of vacuum in the arrow C direction of Fig. 7 is applied to workpiece W2 sharply reduces.Therefore, to the top W of the trailing flank Wc of workpiece W2
lthe power applied upward reduces, the top W of the trailing flank Wc of workpiece W2
leasily height step-down under the effect of inclined plane part 5b.
Then, be transported into, beyond inclined plane part 5b, there is low overhead height h
2the workpiece W2 of below of platform lid 5 part arrive the 1st inspection portion 8 of Fig. 1 with keeping this state, as shown in FIG. 22 and 23, detector Pa and Pb and lead terminal Wa and Wb carry out the inspection of electrical characteristics with abutting.Now, the overhead height of the 1st inspection portion lid 81 becomes the overhead height h than supply unit lid 7x
1low h
2, therefore, as described later, inspection speed can not reduce.
According to the present embodiment, at the inclined plane part 5b of platform lid 5, easily and reliably can revise being separated supply unit 7 place by the posture of workpiece W be supplied to inclination attitude in workpiece reception hole 3, and promptly can carry out the inspection to workpiece W in the 1st inspection portion 8 and the 2nd inspection portion 9.

In following comparative example, as shown in Figure 38 ~ Figure 40, being covered by the platform lid 50 without inclined plane part above of workpiece reception hole 3 except being positioned at the workpiece reception hole 3 being separated supply unit 7, now, platform lid 50 is adjacent to arrange with the supply unit lid 7x being separated supply unit 7.
As shown in figure 15, when workpiece W1 is accommodated in workpiece reception hole 3 by even keel, as shown in Figure 24 ~ Figure 27, by the intermittent rotary of transport platform 2, the workpiece W1 in workpiece reception hole 3 is carried without problems.That is, in Figure 24 of the arrow L direction transparent view as Figure 15, be accommodated with workpiece W1 in workpiece reception hole 3, workpiece sensing portion 13a and 13b detects this state.This Detection Information is sent to control part, control part make as shown in fig. 25 transport platform 2 in the direction of arrow A intermittent rotary carry out conveying workpieces W1.Then, as shown in figure 26, arrive at the workpiece reception hole 3 of sky and be separated supply unit 7, transport platform 2 stops like that as shown in figure 27, then by the effect of control part, stop the separate pins 12 of workpiece W2 to exit to the direction of arrow D, under the effect of the vacuum attraction of workpiece W2 in fig .15 shown in arrow C, be received in workpiece reception hole 3 (Figure 17 and Figure 18).
At this, if utilize vibration along its length linear loader 6 in conveying there is at length direction the workpiece W of lead terminal Wa and Wb, then due to when vibration workpiece W vertically jump, lead terminal Wa, Wb of therefore sometimes adjacent workpiece W overlap each other.Figure 28 and Figure 29 represents this example.Figure 28 represents that the lead terminal Wa of leading workpiece W is overlapped in the state on the lead terminal Wb of follow-up workpiece W, and Figure 29 represents that the lead terminal Wb of follow-up workpiece W overlaps the state on the lead terminal Wa of leading workpiece W.For the action arriving the workpiece W being separated supply unit 7 with the state of wherein Figure 28, use Figure 30 ~ Figure 35 explanation.
Figure 30 is the figure corresponding with Figure 15, represents to be stoped by separate pins 12 and the lead terminal W2a of the workpiece W2 stopped is overlapped in the state of the lead terminal of follow-up workpiece W3.In this condition, as shown in Figure 31 corresponding with Figure 16, transport platform 2 intermittent rotary, as shown in Figure 32 corresponding with Figure 17, empty workpiece reception hole 3 arrives and is separated in supply unit 7 and stops.Now, by the effect of control part, separate pins 12 moves to the direction of arrow D and exits.
Then, as shown in Figure 33 corresponding with Figure 18, the workpiece W2 that separated pin 12 stops and stops moves in the direction of arrow B to workpiece reception hole 3 under the effect of the pull of vacuum of arrow C.Now, contact with 1a above pedestal 1 at the lead terminal W2b of the leading flank Wd side of the moving direction of workpiece W2, the lead terminal W2a of trailing flank Wc side is mobile under the state that 1a above pedestal 1 leaves.Then, under gravity, the lead terminal W2a of the lead terminal W2b of leading flank Wd side and trailing flank Wc side alternately contacts with the 1a above of pedestal 1, workpiece W2 jumps and be incorporated in workpiece reception hole 3.
That is, the state that the 1a above of the lead terminal W2a brought into temporary contact pedestal 1 of the trailing flank Wc side of workpiece W, the lead terminal W2b of leading flank Wd side leave from 1a above pedestal 1 from the state of Figure 33, as shown in figure 34, is become.Then as shown in figure 35, the lead terminal W2b of the leading flank Wd side of workpiece W again contact 1a above pedestal 1, trailing flank Wc side lead terminal W2a again from the state that 1a above pedestal 1 leaves, workpiece W2 is received in workpiece reception hole 3.
Now, to the vacuum attraction from suction hole 11a of workpiece reception hole 3 be from pedestal 1 tiltedly direction arrow C towards carrying out, therefore the lead terminal W2b of the leading flank Wd side of workpiece W2 is oliquely downward attracted, the top W of the trailing flank Wc of workpiece W2
lexerted a force upward.Therefore, the 1a above that the posture of workpiece W2 is fixed to the lead terminal W2b of leading flank Wd side and pedestal 1 contacts, the top W of trailing flank Wc
lwith 7a below supply unit lid 7x
1the abnormal posture abutted.Figure 36 represents the transparent view of looking from the arrow L direction of Figure 35 of this state.In Figure 36, the top W of the trailing flank Wc of workpiece W2
lwith 7a below supply unit lid 7x
1abut.When transport platform 2 starts intermittent rotary in this condition, become the state of Figure 37.In Figure 37, workpiece reception hole 3 portion of the being supplied to lid 7x being accommodated with workpiece W2 covers, and utilize the vacuum attraction from the vacuum passage 11 shown in Figure 35, workpiece W2 is drawn by vacuum passage 11 side draught.Therefore, in the posture of workpiece W2 be the top W of the state of Figure 36 and the trailing flank Wc of workpiece W2
lwith 7a below supply unit lid 7x
1the state abutted, transport platform 2 is to the direction intermittent rotary of arrow A.
Now, the hand of rotation (arrow A of Figure 37) along transport platform 2 is adjacent to setting table lid 50, as mentioned above, with 7a below 1a above pedestal 1 to supply unit lid 7x with supply unit lid 7x
1overhead height h
1compare, the overhead height h of 50a below from 1a above pedestal 1 to platform lid 50
2low.
Therefore, in Figure 37, interface and the 50x of the workpiece W2 in workpiece reception hole 3 and supply unit lid 7x and Tai Gai 50 collide, workpiece W2 or workpiece reception hole 3 impaired.
In order to prevent this situation, consider make 50a below platform lid 50 be positioned at supply unit lid 7x below 7a
1on same plane, make the overhead height of 50a below 1a to platform lid 50 above pedestal 1 and 7a below 1a above pedestal 1 to supply unit lid 7x
1overhead height h
1identical.
But now, below from 1a above pedestal 1 to platform lid 50, the overhead height of 50a becomes and compares h
2high h
1.Equally, be also changed to from the overhead height of 81a below the 1st inspection portion lid 81 of the 1st inspection portion 8 shown in 1a to Figure 22 and Figure 23 above pedestal 1 and compare h
2large h
1.
Now, in the 1st inspection portion 8, detector Pa and Pb advances to lead terminal Wa and Wb of workpiece W, make workpiece W be connected to the 1st inspection portion lid 81 below 81a to check the electrical characteristics of workpiece W, then, when detector Pa and Pb exits, the advance of detector Pa and Pb and the required time exited elongated (with reference to Figure 22 and Figure 23).That is, check that speed reduces, the inspection number of the time per unit of workpiece W reduces.
As an example, during the height Z=1.0mm of the workpiece W in above-mentioned Fig. 2, if overhead height h
2=1.2mm, overhead height h
1=1.4mm, then with overhead height h
2and h
1corresponding required time is 5ms and 8ms respectively.Like this, because overhead height is from h
2become greater to h
1, required time increases 3ms, and this reason causes the per minute of workpiece W to check that number reduces such as 40.Even if this means as mentioned above with the workpiece W of the speed delivery head Z=1.0mm of per minute 900, per minute checks that number also can reduce 40.In recent years, require the conveying of workpiece W and the high speed of inspection, the minimizing of such inspection number reduces as performance, becomes problem.
To this, according to the present invention, at the inclined plane part 5b of platform lid 5, the posture from being separated the workpiece W that supply unit 7 supplies in workpiece reception hole 3 easily and reliably can be revised.And, the overhead height h of the part beyond the inclined plane part 5b in platform lid 5
2than the overhead height h of loader lid 6x and supply unit lid 7x
1low, the overhead height h therefore to 81a below the 1st inspection portion lid 81
2step-down.Therefore, it is possible to shorten at the advance of the 1st inspection portion 8 detector Pa, Pb and the required time that exits, the inspection speed of workpiece W is there will not be to reduce.
