Such as Fig. 1～shown in Figure 23, Work transfer device comprises: pedestal 1, can be configured on the pedestal 1 with rotating freely and transport platform 2 that peripheral part is provided with a plurality of workpiece reception holes 3 with link with transport platform 2 and workpiece W supplied to linear loader 6 in the workpiece reception hole 3 of transport platform 2 via separating supply unit 7.Wherein, be fed device lid 6x above the linear loader 6 and cover, separate supply unit 7 and be positioned at the workpiece reception hole 3 that separates supply unit 7 above the lid 7x of the section of being supplied to covering.And the top of the workpiece reception hole 3 except being positioned at the workpiece reception hole 3 that separates supply unit 7 covered by platform lid 5.
As shown in Figure 1, transport platform 2 is rotated by not shown driver train as described above, in the outside of transport platform 2, vibrate and the linear loader 6 that becomes a row state to carry workpiece is horizontally disposed with towards the purliew of transport platform 2 by not shown vibrating mechanism.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, utilize this separation supply unit 7 with workpiece separate one by one, to 3 supplies of workpiece reception hole.In addition, the peripheral part in transport platform 2 is provided with the 1st inspection section 8, the 2nd inspection section 9, discharge portion 10 successively along intermittent rotary direction (arrow A).
As mentioned above, be fed device lid 6x above the linear loader 6 and cover, the lid 7x of the section of being supplied to covers above the separation supply unit 7, and the top of workpiece reception hole 3 covered by platform lid 5.Therefore, can not directly see workpiece W from upper face side, but in Fig. 3, the workpiece W mark shade line in linear loader 6 and the workpiece reception hole 3 represent as transparent view.
Workpiece W then is described.Fig. 2 represents the block diagram of workpiece W.Workpiece W is made of light-emitting diode (LED), has: the main body Wx and the place ahead from main body Wx to length direction and outstanding lead terminal Wa, the Wb in rear that have the rectangular shape of emitting surface Ws in the above.
When for example workpiece W is positioned at linear loader 6, the leading flank Wd of lead terminal Wb autonomous agent Wx is outstanding, 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 is outstanding, and the bottom surface of lead terminal Wa is consistent with the bottom surface of main body Wx.
Lead terminal Wa and Wb are electrodes, detector described later (probe) Pa and Pb respectively with lead terminal Wa and Wb butt, measure the electrical characteristics of workpiece W.
As the example of the LED that sells on the market, vertical X that main body Wx is arranged is 3mm, laterally Y is that 5mm, height Z are that the length j of the protrusion of 1mm, lead terminal Wa and Wb is that 0.3mm, height k are the LED of 0.25mm.As shown in Figure 4, above-mentioned workpiece W carries emitting surface Ws up in the direction of arrow B towards length direction in linear loader 6.
In Fig. 8, the part mark shade line that pass through at workpiece W.In linear loader 6, the ground of linear loader (bed surface) 6a is vertically vibration under the effect of not shown vibrating mechanism, conveying workpieces W.The ground that is positioned at the ground of separation supply unit 7 of terminal part of linear loader 6 and workpiece reception hole 3 all become pedestal 1 above.
As shown in Figure 7, linear loader 6 above be fed device lid 6x and cover.In addition, the ground 6a of linear loader 6 become loader seat 6y above, this loader seat 6y under the effect of not shown vibrating mechanism, as arrow V vertically the vibration.And as mentioned above, be positioned at linear loader 6 terminal part separation supply unit 7 top and workpiece reception hole 3 above the section of being supplied to lid 7x cover.In addition, the ground of separating the ground of supply unit 7 and workpiece reception hole 3 all becomes the top 1a of pedestal 1, is separating supply unit 7, is provided with the separate pins 12 of vertically freely advancing and retreat in (the most approaching) part that is close to of the workpiece reception hole 3 of pedestal 1.
The 13a of workpiece sensing section in workpiece reception hole 3 never graphic light source send light, the 13b of workpiece sensing section detects this light.Thus, detect in workpiece reception hole 3, whether to have taken in workpiece W.
In addition, separating supply unit 7, the pedestal 1 below transport platform 2 is provided with the vacuum passage 11 that is communicated with not shown vacuum source.Vacuum passage 11 is communicated with the attraction hole 11a of the wall of being located at workpiece reception hole 3 via transport platform 2, the workpiece W in the workpiece reception hole 3 under the effect of vacuum source by the direction attracting holding to arrow C.
Then, the block diagram of Fig. 6 (a), (b) expression workpiece reception hole 3.Fig. 6 (a) is the figure that represents not take in the state of workpiece W, when workpiece reception hole 3 is separating supply unit 7 and stopping, carrying out vacuum attraction from attracting hole 11a to the direction of arrow C.Fig. 6 (b) is illustrated in to separate the figure that supply unit 7 is taken in the state of workpiece W.It is that the outstanding direction of lead terminal Wb is towards the center position ground of transport platform 2 vacuum attraction that workpiece W is made its length direction.
Fig. 5 is illustrated in the appearance of loader 6 interior conveying workpieces W.Workpiece W is a row ground with lead terminal Wa and Wb in the mode of downside and is configured in linear loader ground 6a, by the vibration of the arrow V direction of loader seat 6y and by the direction conveying to arrow B.
At this moment, because the vibration of arrow V direction, workpiece W 6a 6b below loader lid 6x above loader seat 6y jumps, and therefore is set as that height Z than workpiece adds the maximum height of jump and the slightly large value h of value that gets from the overhead height of the ground of linear loader (loader seat 6y above 6a) loader lid 6x below loader lid 6x till the 6b

In order to accelerate the delivery speed of workpiece W, need the amplitude of increase vibration, large if the amplitude of vibration becomes, then the maximum height of workpiece jump becomes large.Therefore, along with delivery speed accelerates, the overhead height h of loader lid 6x
1Uprise.As an example, in order to carry the workpiece W of height Z=1mm among Fig. 2 that it is accommodated in workpiece reception hole 3 with the speed of 900 of per minutes, loader covers the overhead height h of 6x
1Be 1.4mm.
In Fig. 7, pedestal 1 does not vibrate, but workpiece W is jumping to be moved to from linear loader 6 and separates supply unit 7 owing to the vibration of loader seat 6y.Therefore, the following 7a of supply unit lid 7x
1Be positioned at loader and cover on the following 6b same level face of 6x.
On the other hand, the thickness of transport platform 2 is that the height u of workpiece reception hole 3 is the slightly large values of height Z than the workpiece W among Fig. 2.As an example, the height u of workpiece reception hole 3 that takes in the workpiece W of above-mentioned height Z=1mm is 1.1mm.At this, supply unit lid 7x covers the top 2a of the part of transport platform 2, but owing to need to do one's utmost the leakage of the vacuum attraction of the workpiece W of inhibit function in workpiece reception hole 3, the following 7a of supply unit lid 7x
2Be set as minimum with the gap of the top 2a of transport platform 2.As an example, during the height of above-mentioned workpiece reception hole 3 (thickness of transport platform 2) u=1.1mm, 1a 7a below supply unit lid 7x above pedestal 1
2Overhead height h
2Be 1.2mm.That is, the following 7a of supply unit lid 7x

As shown in figure 15, workpiece W1 is accommodated in workpiece reception hole 3 when interior by on even keel, and such as Figure 24～shown in Figure 27, by the intermittent rotary of transport platform 2, the workpiece W1 in the workpiece reception hole 3 are carried without problems.That is, in the Figure 24 as the arrow L direction transparent view of Figure 15, taken in workpiece W1 in the workpiece reception hole 3, the 13a of workpiece sensing section and 13b detect this state.This detection information is sent to control part, control part make like that as shown in figure 25 transport platform 2 in the direction of arrow A intermittent rotary come conveying workpieces W1.Then, as shown in figure 26, workpiece reception hole 3 at sky arrives separation supply unit 7, transport platform 2 stops like that as shown in figure 27, then by the effect of control part, the separate pins 12 of prevention workpiece W2 withdraws to the direction of arrow D, under the effect of workpiece W2 vacuum attraction shown in the arrow C in Figure 15, is received in the workpiece reception hole 3 (Figure 17 and Figure 18).
At this, if utilize vibration to have the workpiece W of lead terminal Wa and Wb in linear loader 6 interior conveyings at length direction along its length, then since when vibration workpiece W vertically jump, therefore lead terminal Wa, the Wb of adjacent workpiece W overlap each other sometimes.Figure 28 and Figure 29 represent this example.Figure 28 represents that the lead terminal Wa of workpiece W in advance 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 workpiece W in advance.For with the wherein action of the workpiece W of the state arrival separation supply unit 7 of Figure 28, use Figure 30～Figure 35 explanation.
Figure 30 is the figure corresponding with Figure 15, and the lead terminal W2a of the workpiece W2 that expression is stopped by separate pins 12 preventions is overlapped in the state of the lead terminal of follow-up workpiece W3.Under this state, as corresponding with Figure 16 shown in Figure 31, transport platform 2 intermittent rotaries, as corresponding with Figure 17 shown in Figure 32, empty workpiece reception hole 3 arrives and separates in the supply units 7 and stop.At this moment, by the effect of control part, separate pins 12 moves and withdraws to the direction of arrow D.
Then, as corresponding with Figure 18 shown in Figure 33, separated pin 12 stops and the workpiece W2 that stops is mobile in the direction of arrow B to workpiece reception hole 3 under the effect of the pull of vacuum of arrow C.At this moment, the lead terminal W2b in the leading flank Wd side of the moving direction of workpiece W2 contacts, begins under the lead terminal W2a state that 1a leaves above pedestal 1 of trailing flank Wc side mobile with 1a above the pedestal 1.Then, under action of gravitation, the lead terminal W2b of leading flank Wd side alternately contacts with the top 1a of pedestal 1 with the lead terminal W2a of trailing flank Wc side, workpiece W2 is jumping and is being incorporated in the workpiece reception hole 3.
That is, from the state of Figure 33, as shown in figure 34, the lead terminal W2a that becomes the trailing flank Wc side of workpiece W temporarily contacts the lead terminal W2b state that 1a leaves above pedestal 1 of the top 1a of pedestal 1, leading flank Wd side.Then as shown in figure 35, again contact under the lead terminal W2a state that 1a leaves above pedestal 1 again of 1a above the pedestal 1, trailing flank Wc side at the lead terminal W2b of the leading flank Wd of workpiece W side, workpiece W2 is received in the workpiece reception hole 3.
At this moment, to the vacuum attraction that comes self-gravitation hole 11a of workpiece reception hole 3 be from the tiltedly lower direction arrow C of pedestal 1 towards carrying out, so the lead terminal W2b of the leading flank Wd side of workpiece W2 is attracted the top W of the trailing flank Wc of workpiece W2 to oblique below
LBy the application of force upward.Therefore, the posture of the workpiece W2 lead terminal W2b that is fixed to leading flank Wd side contact with the top 1a of pedestal 1, the top W of trailing flank Wc
LFollowing 7a with supply unit lid 7x
1The abnormal posture of butt.Figure 36 represents the transparent view that the arrow L direction from Figure 35 of this state is looked.In Figure 36, the top W of the trailing flank Wc of workpiece W2
LFollowing 7a with supply unit lid 7x
1Butt.When transport platform 2 begins intermittent rotary under this state, become the state of Figure 37.In Figure 37, the lid 7x of workpiece reception hole 3 sections of being supplied to that takes in workpiece W2 covers, and is used to the vacuum attraction from vacuum passage shown in Figure 35 11, and workpiece W2 is drawn to vacuum passage 11 side draughts.Therefore, be that the state of Figure 36 is the top W of the trailing flank Wc of workpiece W2 in the posture of workpiece W2
LFollowing 7a with supply unit lid 7x
1The state of butt, transport platform 2 is to the direction intermittent rotary of arrow A.
At this moment, be adjacent to setting table lid 50 along the hand of rotation (arrow A of Figure 37) of transport platform 2 with supply unit lid 7x, as mentioned above, with the 7a below supply unit lid 7x of 1a above pedestal 1
1Overhead height h
1Compare the overhead height h of 1a 50a below platform lid 50 above pedestal 1
2Low.
Therefore, in Figure 37, the interface of the workpiece W2 in the workpiece reception hole 3 and supply unit lid 7x and Tai Gai 50 is that 50x collides, and workpiece W2 or workpiece reception hole 3 are impaired.
In order to prevent this situation, consider to make the following 50a of platform lid 50 to be positioned at the following 7a that covers 7x with supply unit
1On the same plane, make the overhead height and the 7a below supply unit lid 7x of 1a above pedestal 1 of 1a 50a below platform lid 50 above pedestal 1
1Overhead height h
1Identical.
But at this moment, 1a overhead height of 50a below platform lid 50 becomes and compares h above pedestal 1
2High h
1Equally, 1a overhead height of 81a below the 1st inspection section lid 81 of Figure 22 and the 1st inspection section 8 shown in Figure 23 also is changed to and compares h above pedestal 1
2Large h
1
At this moment, in the 1st inspection section 8, detector Pa and Pb advance to lead terminal Wa and the Wb of workpiece W, the following 81a that makes workpiece W be connected to the 1st inspection section lid 81 checks the electrical characteristics of workpiece W, then, when detector Pa and Pb withdraw from, the required time that advances and withdraw from of detector Pa and Pb elongated (with reference to Figure 22 and Figure 23).That is, check Speed Reduction, 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 among above-mentioned Fig. 2, establish overhead height h
2=1.2mm, overhead height h
1=1.4mm is then with overhead height h
2And h
1Corresponding required time is respectively 5ms and 8ms.Like this, since overhead height 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 for example 40.Even this means as mentioned above the workpiece W with the speed delivery head Z=1.0mm of 900 of per minutes, per minute checks that number also can reduce 40.In recent years, require the high speed of conveying and the inspection of workpiece W, 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, can be easily and revise reliably from separating supply unit 7 to the posture of the workpiece W of workpiece reception hole 3 interior supplies.And, the overhead height h of the part beyond the inclined plane part 5b in the platform lid 5
2Overhead height h than loader lid 6x and supply unit lid 7x
1Low, the therefore overhead height h till the 81a below the 1st inspection section lid 81
2Step-down.Therefore, can shorten the required time that advances and withdraw from the 8 detector Pa of the 1st inspection section, Pb, the inspection Speed Reduction of workpiece W can not occur.
