Description
Technical field
The present invention relates to a kind of workpiece classification discharge system and workpiece classification discharging method of workpiece such as electronic unit being classified and discharging, can realize that particularly productivity improves and the workpiece classification discharge system and the workpiece classification discharging method of the densification of device integral body.
Background technology
In the past, known a kind of workpiece classification discharger, be that workpiece absorption with sheet shape electronic unit etc. remains in the workpiece reception hole of the peripheral part that is arranged at the carrying platform, carry out the mensuration of electrical characteristic simultaneously, measurement result according to workpiece is divided into predefined a plurality of classification with workpiece, via discharge pipe workpiece is expelled in the containing box corresponding with each classification.In such device, if the then number increase of containing box of number of categories increase.Therefore with containing box discharge pipe is set respectively accordingly, the number of the workpiece reception hole of carrying platform need cause carrying the maximization of platform on the number of discharge pipe.At this moment, the maximization and the high priceization that cause device.
On the other hand, known have under the situation that the number of containing box increases, and reduces the number of the discharge pipe that workpiece is discharged from the carrying platform, the device (for example patent documentation 1) that near the position containing box connects respectively with discharge pipe branch and for containing box.
Such workpiece classification discharger 100 has as shown in figure 31: index table 102, and intermittently carrying is as the sheet shape electronic unit (hereinafter referred to as workpiece) of checked property and measure; And distributor 103, dispose in abutting connection with ground with this index table 102, distribute each the workpiece W that measures after finishing according to measurement result.
In Figure 31, by the adsorbed workpiece W of adsorption nozzle 108, and measure by determinator (not shown) by rotation carrying at intermittence of index table 102.Each workpiece W is assigned to a plurality of classification corresponding with measurement result respectively, and by distributor 103 be stored in each corresponding workpiece containing box 115A that classifies in.
According to the measurement result from each workpiece W of determinator, control device CD-ROM drive motor.Thus, make the bottom 113B of swing pipe 113 move to distribution openings 114A that each workpiece W should be assigned with near the top position.And index table 102 is carried to workpiece W after the B of release position, removes the negative pressure of adsorption nozzle 108, from nozzle 111 ejection Compressed Gas, workpiece W is sent in the input pipe 112.At this moment, this workpiece W is by after dropping into pipe 112, through swing pipe 113 and this distribution openings 114A, be stored in the corresponding workpiece containing box of the classification of measurement result 115A in.

For example, nearest be 128,256 or 512 etc. with the number of categories in the classification of workpiece such as light-emitting diode and the workpiece classification discharger of discharging, become very big, if realize and the corresponding workpiece classification of these number of categories discharger by technology in the past, then Zhuan Zhi cost becomes very high, and the high speed of action becomes very difficult.
And because the high pairing workpiece containing box of the classification 115A of aforesaid occurrence frequency becomes full in early days, the power supply that then produces shearing device stops device and with the operation of the full workpiece containing box 115A of empty new workpiece containing box exchange change.At this moment, distribution openings 114A is in open state, therefore exists in foreign matter such as rubbish in the swap operation and enters and sneak into the problem of workpiece containing box 115A from distribution openings 114A.
Also want the power supply of shearing device that device is stopped under the situation of operational example beyond swap operation as the maintenance test operation of device, therefore produce same situation.And, also produce same situation under the situation about promptly stopping in the device any fault of generation.In order to prevent that foreign matters such as rubbish from entering from distribution openings 114A like this, need be when device stops the mechanism of enclose distributor mouth 114A, cause the cost of device to improve.

If under this state, spray Compressed Gas from squit hole 10 to workpiece W, then shown in Fig. 3 (b), workpiece W is admitted to and discharges in the module 81.Fig. 3 (c) (d) (e) illustrate respectively among 4 layers of basic 81A of stratum that discharge module 81, the workpiece reception hole 3 opposed situations of the basic II of stratum, III, IV and carrying platform 2 shown in Figure 5.At this, discharge the order decline of module 81 with Fig. 3 (a)-Fig. 3 (c)-Fig. 3 (d)-Fig. 3 (e), accompany with it, coil 86 compressions that are made of retractile spring prevent from flatly to extend from the back side of the basic 81A of stratum and change into pipe 85 distortion towards the belows of about 90 degree.And coil 86 is made of spring so has the gap in periphery.Thus, the Compressed Gas that sprays to workpiece W from the spray-hole 10 of Fig. 4 (a) along with workpiece W when workpiece outlet 8x arrives coils 86 via pipe 85, this Compressed Gas can discharge to the outside from the gap of coil 86, transporting compressed gas body above the workpiece W not in the time of in workpiece W falls to workpiece containing box 115.Thus, workpiece W becomes near the state that falls naturally, is accommodated in newly that workpiece W in the workpiece containing box 115 can not be compressed that gas pushes and with the inwall of workpiece containing box 115 or be accommodated in workpiece W in the workpiece containing box 115 and conflict and damage.And, do not have yet Compressed Gas with being accommodated in that workpiece W in the workpiece containing box 115 meets problem that this workpiece W is kicked up once more.
And Fig. 3 (f) illustrates module 81 integral body and and the situation that stop also more opposed by the outer peripheral face 1a of the pedestal 1 of below than carrying platform 2 of discharging.This state is for maintenance test etc. and during the power supply of shearing device, or produces any fault and state during emergency braking device at device.Stop by this position that acts on by control part 9, whole workpiece outlet 8x is by the outer peripheral face 1a of pedestal 1 sealing, prevents that foreign matter such as rubbish from entering workpiece containing box 115 from outlet 8x.
In addition, can be as shown in figure 30, will manage 85 with discharge module 81 and be connected, and should manage 85 and be configured in sliding freely in the large diameter pipe 85A.And large diameter pipe 85A is fixed on the supporting station 87.
In Figure 30, along with the lifting of discharging module 81, pipe 85 can move along above-below direction in large diameter pipe 85A.At this moment, the external diameter of pipe 85 is slightly littler than the internal diameter of large diameter pipe 85A.
Then, the following describes the effect of the present embodiment of such structure.
At first, in Fig. 1, workpiece W is housed in the peripheral part 2a that rotation is arranged on the carrying platform 2 on the pedestal 1 freely and goes up in the set workpiece reception hole 3, and by the effect of not shown drive unit, carrying platform 2 is intermittently rotation (arrow A of Fig. 1) clockwise around central shaft 4.
And when the workpiece W in workpiece reception hole 3 arrived workpiece determination part 7, by the electrical characteristic of this workpiece determination part 7 mensuration workpiece W, the workpiece W that measures after finishing arrived discharge portion 8a, 8b.Workpiece W is divided into predefined a plurality of classification according to the measurement result that is sent to each workpiece W of control part 9 from workpiece determination part 7 by control part 9, and discharges to the workpiece containing box corresponding with this classification 115.
Each discharge portion 8a, 8b are shown in the front view of Fig. 5, and the discharge module 81 that has these 4 basic 81A of stratum of I～IV of (1)～(8) 8 workpiece outlets 8x by comprising forms.
The discharge module 81 that constitutes discharge portion 8a, 8b moves freely on vertical direction (arrow C of Fig. 2) integratedly by driving mechanism 81a.And, by discharge module 81 to the moving of vertical direction, be lifting, as Fig. 3 (a) (c) (d) (e) shown in, the workpiece W in the workpiece reception hole 3 of carrying platform 2 can and the workpiece outlet 8x of the basic 81A of stratum of I～IV opposed respectively.
Thus, make and discharge the basic stratum 81A formation of module 81 by a plurality of stratum (I～IV is these 4 layers in Fig. 5), and lifting integratedly, make the workpiece W in workpiece outlet 8x and the workpiece reception hole 3 freely opposed.Thus, even it is big that predefined number of categories becomes, the number ((1) among Fig. 5～(8)) of workpiece outlet 8x on the basic 81A of stratum that is formed on a stratum is increased, the number increase that can make workpiece outlet 8x by stratum's number is increased.Thus, big even number of categories becomes, do not need to make the number of the workpiece reception hole 3 of carrying platform 2 to increase yet, promptly do not need to increase the diameter of carrying platform 2, therefore can make equipment miniaturization.And, discharge module 81 and only move along vertical direction, so the simple structure of drive unit 81a, move the needed time and also lack.
Then, describe the classification discharging method of the workpiece W among discharge portion 8a, the 8b in detail according to Fig. 6～Figure 28.Fig. 6～Figure 28 schematically shows the carrying platform 2 seen from the arrow T direction of Fig. 2 and the position relation of discharge portion 8a, 8b.
Like this, can workpiece W be divided into predefined 64 classification according to the measurement result of the workpiece W in the workpiece determination part 7 of Fig. 1.
At this, Fig. 6～Figure 28 and Fig. 5 illustrate the workpiece outlet 8x of each discharge portion 8a, 8b in the same manner with horizontal 8, perpendicular 4 form, give the symbol of workpiece outlet 8x mark (1)～(8) of transverse direction, give the symbol of the basic 81A of the stratum mark I～IV of longitudinal direction.And, on the workpiece outlet 8x of each discharge portion 8a, 8b, illustrate as 1～64 of number of categories with continuous symbol.For example, the I of discharge portion 8a (3) is equivalent to classify 3, and the III of discharge portion 8b (6) is equivalent to classify 46.
At this, the discharge module 81 of discharge portion 8a, 8b all with the workpiece outlet 8x of the basic 81A of stratum of I and carrying platform 2 become equal height state, be that the state that Fig. 3 (a) illustrates is an initial condition.And, by control part 9 81a of controlling and driving mechanism, discharge module 81 liftings, move to (d) each state of (e) of Fig. 3 (c).And, in Fig. 6～Figure 28, with horizontal row the workpiece reception hole 3 of carrying platform 2 is shown in the same manner with above-mentioned workpiece outlet 8x, each workpiece reception hole 3 is marked with the classifying and numbering (any of 1～64) of the discharge order that the workpiece W that is accommodated in the workpiece reception hole 3 is shown to be marked at the alphabetical small character identification of downside.
For easy, in Fig. 6～Figure 28, the number of workpiece reception hole 3 is defined as these 18 of a～r.When carrying platform 2 when the arrow A direction of Fig. 2 is intermittently rotated, in Fig. 6～Figure 28, carrying platform 2 advances to the direction of arrow A.In Fig. 6, be accommodated in workpiece reception hole 3 (a, b, c, d ...) in the classifying and numbering of workpiece W be followed successively by 1,5,14,10 ...This means that for example the workpiece W of workpiece reception hole a is I (1) discharge of discharge portion 8a from workpiece outlet 1, the workpiece W of workpiece reception hole b is I (5) discharge of discharge portion 8a from workpiece outlet 5.For convenience, for example in Fig. 6, carrying platform 2 discharge portion 8a, 8b slightly below mark, go up on the identical plane of set workpiece outlet I (1)～I (8) (classifying and numbering 1～16) but in fact then be present in the basic I of stratum of discharge portion 8a, 8b.In Fig. 7～Figure 28, the position of carrying platform 2 and discharge portion 8a and 8b relation also is identical.
Below, key diagram 6～Figure 28 in order, but, " workpiece reception hole " is designated as " reception hole " for easy, " workpiece outlet " is designated as " outlet ".
When carrying platform 2 when the initial condition of Fig. 6 is intermittently rotated, become the state of Fig. 7.At this, the workpiece W of the reception hole a of carrying platform 2 is opposed with the outlet 1 (I of discharge portion 8a (1)) that should be discharged from.
In Fig. 7,, stamped shade for reception hole a and outlet 1 for clear and definite this point.In Fig. 8～Figure 28, corresponding reception hole and outlet stamped shade when also giving with same case below.
This testing result is sent to control part 9, if confirm not have other workpiece W that should be discharged from stage control part 9 as shown in Figure 7, then control part 9 makes intermittently rotation of carrying platform 2, moves to the state of Fig. 8.
In Fig. 8, reception hole b and outlet 1 are opposed.At this moment, control part 9 confirms that the workpiece W in the reception hole b is discharged to outlet 5, even under the state of Fig. 8, make discharge module 81 liftings of discharge portion 8a, with the opposed outlet of reception hole b also be some in 17 (II (1)), 33 (III (1)), 48 (IV (1)), therefore the control part 9 workpiece W that judges and will do not discharged at the state of Fig. 8, make intermittently rotation of carrying platform 2, move to the state of Fig. 9.
In Fig. 9, about the workpiece W in reception hole b and the reception hole c, control part 9 and the situation of Fig. 8 are judged does not in the same manner have the workpiece W that will be discharged from, and makes intermittently rotation of carrying platform 2, moves to the state of Figure 10.
Be in the same manner in Figure 10 and Figure 11, control part 9 judges at the state of each figure does not have the workpiece W that will be discharged from, and makes intermittently rotation of carrying platform 2, moves to the state of Figure 12 yet.At this, in Figure 12, the workpiece W of reception hole b is opposed with the outlet 5 that should be discharged from (I of discharge portion 8a (5)).Therefore the situation of control part 9 and Fig. 7 sprays Compressed Gas from squit hole 10 in the same manner, and W sends into outlet 5 with this workpiece.And, detect workpiece W by light source 11a and photodetector 11b and be fed through outlet 5 from reception hole b, and this check result is sent to control part 9, under the stage as shown in figure 12, the workpiece W that control part 9 affirmations do not have other to discharge, then control part 9 makes intermittently rotation of carrying platform 2, moves to the state of Figure 13.
In Figure 13～Figure 16, identical with Fig. 8, control part 9 judges at the state of each figure does not have the workpiece W that will be discharged from, and makes intermittently rotation of carrying platform 2, moves to the state of Figure 17.
In Figure 17, the outlet 20 (II of discharge portion 8a (4)) that should discharge the workpiece W in the reception hole h descends by the discharge module 81 that makes discharge portion 8a and opposed with reception hole h.Therefore, control part 9 81a of controlling and driving mechanism descend the discharge module 81 of discharge portion 8a, make the basic 81A of stratum of II be positioned at the height identical with carrying platform 2.And, with the situation of Fig. 7 in the same manner from squit hole 10 ejection Compressed Gas, W sends into outlet 20 with this workpiece.And light source 11a and photodetector 11b detect workpiece W and are admitted to outlet 20 from reception hole h, and this testing result is sent to control part 9.
Then, under this state, the outlet 39 (III of discharge portion 8a (7)) that should discharge the workpiece W in the reception hole e descends once more by the discharge module 81 that makes discharge portion 8a and opposed with reception hole e.Therefore, as shown in figure 18, control part 9 81a of controlling and driving mechanism descend the discharge module 81 of discharge portion 8a, make the basic 81A of stratum of III be positioned at the height identical with carrying platform 2.And, with the situation of Fig. 7 in the same manner from squit hole 10 ejection Compressed Gas, W sends into outlet 39 with this workpiece.And light source 11a and photodetector 11b detect workpiece W and are admitted to outlet 39 from reception hole e, and this testing result is sent to control part 9.
At this, in Figure 17 and Figure 18, under the state that carrying platform 2 is stopped, discharging two workpiece W continuously from reception hole h and reception hole e.
Under these circumstances, in the prior art, in Figure 30, when workpiece W is expelled to different workpiece containing boxs 115 continuously, in case just be directed to the distribution openings 114A corresponding with each workpiece containing box 115 by dropping into pipe 112 back workpiece W.Therefore in technology in the past, need after detecting the outlet of workpiece W, will drop into pipe 112 and move to the distribution openings 114A that discharges next workpiece W by input pipe 112.
Relative therewith, according to the present invention, the path of the discharge pipe from workpiece reception hole 3 to workpiece containing box 115 is independent fully, therefore as long as light source 11a and photodetector 11b detect workpiece W to discharge just can make at once from workpiece reception hole 3 and discharge module 81 liftings, can make workpiece outlet 8x and the workpiece reception hole 3 of next discharge workpiece W opposed.Therefore, can shorten the time of discharging workpiece W significantly.The workpiece W number of being discharged in carrying the stopping of platform 2 increases more, and the effect that this time shortens is big more.
In Figure 18, when the workpiece W in the discharge reception hole e, even the workpiece W that control part 9 affirmations make discharge module 81 liftings of discharge portion 8a, 8b also not have other to discharge from this state.And then control part 9 makes intermittently rotation of carrying platform 2, moves to the state of Figure 19.
In Figure 19, the discharge module 81 of discharge portion 8a is risen, make the basic 81A of stratum of I be positioned at the height identical with carrying platform 2.At this moment, the workpiece W of reception hole i, j is opposed with the outlet 4,3 that should be discharged from (I of discharge portion 8a (4), I (3)) respectively.
Therefore, control part 9 81a of controlling and driving mechanism rise the discharge module 81 of discharge portion 8a, make the basic 81A of stratum of I be positioned at identical height with carrying platform 2, spray Compressed Gas from squit hole 10 in the same manner with the situation of Fig. 7, this workpiece W is sent into outlet 4,3.At this moment, can side by side carry out for reception hole i, j from the reality of squit hole 10 ejection Compressed Gas.
In this case, in the conventional art, when workpiece W is expelled to workpiece containing box 115, in case just be directed to and the corresponding distribution openings 114A of each containing box by dropping into pipe 112 back workpiece W.Therefore, continuously workpiece W is being expelled under the situation of different workpiece containing boxs 115, need after detecting the outlet of workpiece, will dropping into pipe 112 and move to the next distribution openings 114A that discharges workpiece W by input pipe 112.
Relative therewith, according to the present invention, the path of the discharge pipe from workpiece reception hole 3 to workpiece containing box 115 is independent fully, therefore discharging under the situation of workpiece W to a plurality of workpiece outlet 8x that belong to the identical basic 81A of stratum, can side by side discharge workpiece W.Thus, can shorten the time of discharging workpiece W significantly.The workpiece W number of discharging from the same 81A of stratum in carrying the stopping of platform 2 increases more, and the effect that this time shortens is big more.Thus, if will be arranged on as the outlet among Figure 19 4,3 in the identical basic stratum with the high corresponding workpiece outlet of the classification 8x of occurrence frequency, then can further increase this time shortens effect.
In Figure 19, light source 11a and photodetector 11b detect workpiece W and are admitted to outlet 4,3 from reception hole i, j, and this check result is sent to control part 9, the workpiece W that control part 9 affirmations do not have other to discharge under the stage as shown in figure 19.At this moment, control part 9 makes intermittently rotation of carrying platform 2, moves to the state of Figure 20.
In Figure 20, discharge the interior workpiece W of reception hole d from outlet 10 (I of discharge portion 8b (2)), carrying platform 2 intermittently rotates, and moves to the state of Figure 21.In Figure 21 and Figure 22, the workpiece W that is not discharged from, carrying platform 2 intermittently rotates, and moves to the state of Figure 23.In Figure 23, discharge the interior workpiece of reception hole c from outlet 14 (I of discharge portion 8b (6)), carrying platform 2 intermittently rotates, and moves to the state of Figure 24.
In Figure 24, the outlet 52 (IV of discharge portion 8a (4)) that should discharge the workpiece W in the reception hole n descends by the discharge module 81 that makes discharge portion 8a and opposed with reception hole n.Simultaneously, the outlet 43 (III of discharge portion 8b (3)) that should discharge the workpiece W in the reception hole g descends by the discharge module 81 that makes discharge portion 8b and opposed with reception hole g.
Like this, have separately alone discharge module 81, can carry out the shortening of the efflux time of workpiece W by discharge portion 8a, 8b.
After the discharge of workpiece W among Figure 24, even the workpiece W that control part 9 affirmations make discharge module 81 liftings of discharge portion 8a, 8b also not have other to discharge from this state.Then, control part 9 makes intermittently rotation of carrying platform 2, moves to the state of Figure 25.
In Figure 25, the outlet 2 (I of discharge portion 8a (2)) that should discharge the workpiece W in the reception hole q rises by the discharge module 81 that makes discharge portion 8a and opposed with reception hole q.Simultaneously, the outlet 61 (IV of discharge portion 8b (5)) that should discharge the workpiece W in the reception hole f descends by the discharge module 81 that makes discharge portion 8b and opposed with reception hole f.
The lifting of the discharge module 81 of discharge portion 8a and 8b can be carried out respectively, and as illustrated in fig. 19, can be side by side send into workpiece W to the outlet 8x that is positioned at the basic 81A of stratum of equal height with carrying platform 2, therefore, make discharge module 81 risings of discharge portion 8a and make the basic 81A of stratum of I be positioned at identical height, meanwhile make discharge module 81 declines of discharge portion 8b and make the basic 81A of stratum of IV be positioned at identical height with carrying platform 2 with carrying platform 2.Thus, can when the workpiece W in the reception hole q is sent into outlet 2, the workpiece W in the reception hole f be sent into outlet 61.
Then, control part 9 as shown in figure 26, the discharge module 81 of judgement by making discharge portion 8a descends and should to discharge the outlet 22 (II of discharge portion 8a (6)) of the workpiece W in the reception hole m opposed with reception hole m, make discharge module 81 declines of discharge portion 8a and make the basic 81A of stratum of II be positioned at identical height, the workpiece in the reception hole m is sent into outlet 22 with carrying platform 2.
At this moment, even the workpiece W that control part 9 affirmations make discharge module 81 liftings of discharge portion 8a, 8b also not have other to discharge from this state.Then, control part 9 makes intermittently rotation of carrying platform 2, moves to the state of Figure 28.In Figure 28, the workpiece W of reception hole o, p, r is opposed with the outlet 37,36,34 that should be discharged from (III of discharge portion 8a (5), III (4), III (2)) respectively, and the workpiece W of reception hole k is opposed with the outlet 57 that should be discharged from (IV of discharge portion 8b (1)).Therefore control part 9 is side by side sent these workpiece W into each outlet 8x.In this case, also the situation with shown in Figure 19 is identical, as long as the classification corresponding outlet 8x high with occurrence frequency, distribute to the outlet 37,36,34 that is arranged among the identical basic 81A of stratum, then the shortening effect of efflux time becomes remarkable.
According to such present embodiment, even under the situation that the number of categories of workpiece increases, the number of the workpiece reception hole of carrying platform is increased, and do not make and discharge processing speed and reduce.And, can at high speed workpiece be expelled in the workpiece containing box corresponding with the high classification of occurrence frequency.
