(electronic devices and components holding device)
Fig. 1 means the lateral plan that the integral body of electronic devices and components holding device 1 forms.Electronic devices and components holding device 1 shown in Fig. 1 is electronic devices and components D to be delivered to the device of step process unit 74 (with reference to Figure 11).Step process unit 74 is devices that electronic devices and components D implementation step is processed, and comprises winding unit 6.Winding unit 6 is intermittently to transfer to take in the carrying belt 61 that the bag 62 of electronic devices and components D processes through embossing (emboss).
For winding unit 6, electronic devices and components holding device 1 is inserted into electronic devices and components D in bag 62, and in bag 62, makes electronic devices and components D depart from.Now, electronic devices and components holding device 1 is not suitably inserted into the direct bale packing of bad goods that produces in bag 62 at carrying belt 61 by preventing because of electronic devices and components D.That is, electronic devices and components holding device 1 is in the abnormal contact of the insertion stage detected electrons components and parts D to bag 62.Abnormal contact detecting method is induction carrying belt 61 with electronic devices and components D while the method that contacts the resistance of generation while continuing to carry out inserting step.
This electronic devices and components holding device 1 mainly comprises maintaining part 2, pressing body 3 and motor 4 for lifting.Maintaining part 2 keeps electronic devices and components D on one side, on one side the lifting by external force.Lifting produces the decline power of maintaining part 2 with motor 4, again, control Bottom Of Descent and the descending speed of maintaining part 2.Pressing body 3 mainly produces lifting decline power with motor 4 is passed to maintaining part 2.
Maintaining part 2 is for example adsorption mouth.The inside of this maintaining part 2 is the pipeline (pipe) of hollow, and has opening at front end.Via the joint 25 that is connected in rear end, pipe interior is communicated with pneumatic circuit, and at front end attract electrons components and parts D, by vacuum breaking, electronic devices and components D is departed from by the generation of vacuum.Also can discharge electronic devices and components D is departed from by atmosphere, also can sequentially switch vacuum breaking and atmosphere and discharge, electronic devices and components D is departed from.
The support arm 21 that this maintaining part 2 is fixed by the height with respect to bag 62 supports, and is positioned at the top of bag 62.Support arm 21 extends substantially in parallel with respect to the opening surface of bag 62, and connects at front end the vertical bearing 22 of opening surface that is provided with relative bag 62.Maintaining part 2 makes the front end that is provided with opening be inserted into bearing 22 towards bag 62, thereby by support arm 21, is supported slidably.

Pressing body 3 will be supported in linear guides (linear guide) 31 slidably in the direction of maintaining part 2 depress.The rail portion of linear guides 31 extends upward in the side vertical with bag 62, and highly fixing.In the lower end of pressing body 3, extend and be provided with rod member 32.Rod member 32 is towards the backend arrangement of maintaining part 2, and axis and maintaining part 2 common.Pressing body 3 decline of sliding on linear guides 31, and by the lower end of rod member 32, be connected to the rear end of maintaining part 2, thus the external force towards descent direction is passed to maintaining part 2.
This pressing body 3 has the roughly framework 33 of コ font Like.Pressing body 3 is supported by linear guides 31 in the part at the back side of framework 33, at the underarm 33a of framework 33, comprises rod member 32.The underarm 33a of framework 33 extends with respect to the opening surface on even keel of bag 62, and in the part of the axes intersect of its front end and maintaining part 2, rod member 32 is installed.Rod member 32 is installed orthogonally with the bearing of trend of underarm 33a, and front end and rear end giving prominence to up and down from underarm 33a.
At the upper arm 33b of framework 33, surface is provided with cam follower (camfollower) 34 thereon.This cam follower 34 is in order to transmit the rotational force of motor 4 for lifting, pressing body 3 depress to be arranged.Lifting is for example servomotor with motor 4.On S. A. in lifting with motor 4, be fixed with druum cam 41.Druum cam 41 and cam follower 34 butts, cam follower 34 is driven along the camming surface of druum cam 41.
Lifting is converted to along the power of the rectilinear direction of linear guides 31 with cam follower 34 by this druum cam 41 with the rotational force of motor 4, while and pressing body 3 push maintaining part 2 and decline.When maintaining part 2 is declined, lifting with motor 4 so that maintaining part 2 rotates S. A. with rotative speed and torque (torque) that rod member 32 declines with specified speed in the lump.Again, the rotation amount of setting in the mode that is equivalent to arrive the Bottom Of Descent of regulation with maintaining part 2 makes S. A. rotation.The Bottom Of Descent of maintaining part 2 is places of the electronic devices and components D bottom surface that arrives bag 62 or from the place, top of bottom surface fixed distance.Lifting is by lifting is controlled with the power supply of motor 4 with rotative speed, torque and the rotation amount of motor 4.
Herein, pressing body 3 also comprises that induction contacts and continue to carry out simultaneously the testing agency of the resistance that inserting step produces because of carrying belt 61 with electronic devices and components D.The test section 38 that this testing agency is the slide mechanism that detects rod member 32, provide the voice coil motor 37 of thrust and rod member 32 to rise for the relativism of voice coil motor 37 to rod member 32.Moreover in other words rise for the relativism of voice coil motor 37 is that rod member 32 is for the embedding of voice coil motor 37.
Particularly, in the underarm 33a of framework 33, connect the vertical bearing 35 of opening surface that is provided with relative bag 62.Rod member 32 is inserted in this bearing 35, and can slide on the axis direction of rod member 32.Moreover, at the lower surface of the underarm 33a of framework 33, be provided with and there is the Compress Spring 36 that makes the application force that rod member 32 enters from voice coil motor 37, to assist the thrust of voice coil motor 37.
Voice coil motor 37 is fixed on the lower surface of the upper arm 33b of framework 33.The rear end side of these voice coil motor 37 supporting rods 32, makes rod member 32 enter and retreat.Voice coil motor 37 is linear motors (linear motor) that electric current and thrust exist proportionate relationship, and as shown in Figure 2, comprises magnet 37a and annulus (coil) 37b.Annulus 37b and rod member 32 link, and rod member 32 and annulus 37b interlock.Magnet 37a approaches annulus 37b and gives magnetic field.If annulus 37b energising, annulus 37b is placed in electromagnetic field, produces Lao Lunzili (Lorentz force) in annulus 37b.Thus, to being connected in the rod member 32 of annulus 37b, in the direction towards maintaining part 2, give thrust.
Voice coil motor 37 produces the antagonism thrust Fopp equating with the antagonistic force Fcr for this rod member 32 producing because of 32 pairs of maintaining parts of rod member, 2 transmission decline power Fr.That is, voice coil motor 37 produces the static thrust of the state of equilibrium that keeps rod member 32, with suitable power, maintains rod member 32 with respect to the position of voice coil motor 37.
As shown in Figure 3, test section 38 comprises air scoop 38a and opens and closes the cap 38b of this air scoop 38a.Air scoop 38a is the opening with the advance and retreat direction quadrature of rod member 32, and is arranged on the upper surface of the underarm 33a of framework 33.Cap 38b be positioned at air scoop 38a directly over, and with rod member 32 linkedly mobile mode from outstanding setting of side face of rod member 32.Outstanding setting position is not to be connected under the state of maintaining part 2 at rod member 32, the height of cap 38b coating air scoop 38a.As shown in Figure 4, air scoop 38a becomes one end of the pipeline 38c that is connected in pneumatic circuit 38e, and is provided with flow counter 38d in pipeline 38c inside.As flow counter 38d, the differential pressure measuring portion of for example detecting for the differential pressure in two regions that discharge orifice outstanding in pipeline (orifice) and discharge orifice are divided.
This test section 38 detects by inflow or the outflow of the air of air scoop 38a, thus to rod member 32 for voice coil motor 37 relativisies situation about rising detect.Its reason is, if rod member 32 rises, cap 38b is separated from air scoop 38a.

Motor control portion 51 controls torque, rotative speed and the rotation amount of motor 4 for lifting.In the situation that lifting is servomotor with motor 4, motor control portion 51 comprises coder (encoder) and torque master.VCM control part 52 is controlled the thrust of voice coil motor 37.The signal of abnormal contact detection unit 53 based on from test section 38, judges the abnormal contact of electronic devices and components D to bag 62.Moreover this control part 5 can be set to a part for the formation of electronic devices and components holding device 1, also can be set to a part for the control part 75 of following electronic devices and components Handling device 7.
Fig. 6 means the diagram of circuit of the control action of this control part 5, below, the state of the control action of control part 5 and electronic devices and components holding device 1 is described in the lump.
First, electronic devices and components D is being inserted into the stage of carrying belt 61, with the axis of maintaining part 2, is passing through in advance the mode of the bottom center of bag 62, carrying out the location of maintaining part 2 and bag 62.Particularly, maintaining part 2 stops at the setting position of winding unit 6, and winding unit 6 lays out carrying belt 61, thus, makes empty bag 62 move to the stop position of maintaining part 2.Again, at the pipe interior of maintaining part 2, produce negative pressure, in the front end absorption of maintaining part 2, have electronic devices and components D.
In the insertion stage, at step S01, motor control portion 51 makes lifting start to drive with motor 4.Motor control portion 51 makes lifting with motor 4, produce the power that maintaining part 2 and rod member 32 are together declined via this rod member 32.
Driving by this lifting with motor 4, druum cam 41 rotations, the cam follower 34 that is connected to the camming surface of druum cam 41 is subject to the thrust towards bag 62.Thrust towards bag 62 becomes pressing body 3 towards the displacing force of maintaining part 2, and pressing body 3 is declined along linear guides 31.If pressing body 3 declines, rod member 32 is connected to the rear end of maintaining part 2.Motor control portion 51 and then lifting is driven with motor 4, thus, pressing body 3 is by maintaining part 2 depress.Maintaining part 2 is resisted above the pushing away application force of Compress Spring 23 and is started to decline.
Now, as shown in Figure 7, maintaining part 2 is from the rod member 32 power Fr that is subject to declining, and rod member 32 is subject to its antagonistic force Fcr.This antagonistic force Fcr is in the situation that be provided with the Compress Spring 23 that maintaining part 2 is up pushed away, and equates with the resistance of the elastic force of Compress Spring 23 for being exerted pressure on prolonging direction.Again, in the situation that be provided with the Compress Spring 36 of rod member 32 depress, the resistance of power that the suffered antagonistic force Fcr of rod member 32 and the elastic force of Compress Spring 23 for self-sustaining portion 2 deduct the elastic force gained of this Compress Spring 36 equates.
Again, in the insertion stage, at step S02, VCM control part 52 makes voice coil motor 37 start to drive, and at rod member 32, produces the antagonism thrust Fopp equating with antagonistic force Fcr.It is with motor 4, to produce thrust simultaneously with lifting that this voice coil motor 37 starts to drive, or before rod member 32 is about to be connected to maintaining part 2.The antagonism thrust equating with antagonistic force Fcr is Fopp, and is identical with antagonistic force Fcr size but the thrust of opposite direction.Strict, along with Compress Spring 23 is compressed, antagonistic force Fcr increases, but also can pass through VCM control part 52, and will resist thrust Fopp, controls as proportionally to increase with antagonistic force Fcr.
Now, as shown in Figure 7, rod member 32 is subject to antagonistic force Fcr, but owing to being subject to resisting thrust Fopp from voice coil motor 37, so act on the force balance of rod member 32, rod member 32 maintains state of equilibrium, and voice coil motor 37 is not advanced and retreat relatively.Again, as shown in Figure 8, in the situation that maintaining the state of equilibrium of rod member 32, cap 38b covers air scoop 38a, the inflow or the outflow that from air scoop 38a, do not produce air.
Then,, in step S03, extremely contact 53 pairs of test sections of detection unit 38 and rod member 32 whether detected and rise and judge.
When rod member 32 is maintaining state of equilibrium, do not produce rod member 32 for the relativism rising of voice coil motor 37, so cap 38b is keeping covering air scoop 38a.Therefore, the value of flow counter is unchanged, and test section 38 exports steady state value to abnormal contact detection unit 53.Extremely contact detection unit 53 by the output valve of pre-stored threshold value and test section 38 is compared, thereby confirm that this output valve is steady state value, and be considered as not detecting rod member 32 risings based on this confirmation.
On the other hand, there is following situation: because position skew appears in any in the position of the position of maintaining part 2, the maintenance form of electronic devices and components D or bag 62, so as shown in Figure 9, in the decline of maintaining part 2 midway, electronic devices and components D contacts with carrying belt 61.Now, while resistance Fd when rod member 32 is subject to making carrying belt 61 distortions make electronic devices and components D and maintaining part 2 continue to decline.
Voice coil motor 37 is only given and being become rod member 32 | the antagonism thrust Fopp of Fcr|=|Fopp|, so become | and Fopp| < | Fcr+Fd|, rod member 32 is produced to raising force Ff, state of equilibrium is broken.Therefore, rod member 32 rises for voice coil motor 37 relativisies, in the side contrary with bag 62, moves up.
As shown in figure 10, if rod member 32 rises, the cap 38b of coating air scoop 38a is separated from air scoop 38a.Among the air scoop 38a opening from cap 38b, air flows into or flows out, and changing appears in the value of flow counter 38d.Extremely contact detection unit 53 by the output valve of threshold value and test section 38 is compared, thereby confirm that this output valve is changing value, and be considered as detecting rod member 32 risings based on this confirmation.
If rod member 32 detected, rise (step S03 is), this situation represents that electronic devices and components D is contacted with bag 62 extremely.Therefore,, in step S04, by the electronic devices and components Handling device 7 of next explanation, implement to process action.
On the other hand, if rod member 32 detected, do not rise (step S03, no),, in step S05, whether the slippage of 51 pairs of maintaining parts 2 of motor control portion reaches setting value is judged.Setting value is corresponding to electronic devices and components D, to arrive the bottom surface of bag 62.If the slippage of maintaining part 2 does not reach setting value (step S05, no), extremely contact 53 pairs of detectors of detection unit and rod member 32 whether detected and rise and judge (step S03), until maintaining part 2 arrives Bottom Of Descents (step S05 is).
If rod member 32 rising (step S03 do not detected, no), and the slippage of maintaining part 2 arrives setting value (step S05 is), abnormal contact detection processing finishes, and electronic devices and components holding device 1 implements electronic devices and components D to be accommodated in the residue action of bag 62.That is, make electronic devices and components D depart from maintaining part 2, and make maintaining part 2 increase.Particularly, destroy the vacuum of the pipe interior of maintaining part 2, electronic devices and components D is departed from.Then, by making druum cam 41 and then rotation, and remove to be situated between by being pressed into of 34 pairs of pressing bodies 3 of cam follower, thus, maintaining part 2 to be discharged from rod member 32, and make maintaining part 2 increase by the application force of Compress Spring 23.
(electronic devices and components Handling device 7)
Secondly, electronic devices and components Handling device 7 is described, this electronic devices and components Handling device 7 is mounted with this kind of electronic devices and components holding device 1, and the processing while abnormal contact being detected.Figure 11 means the birds-eye view that the integral body of electronic devices and components Handling device 7 forms, and Figure 12 is lateral plan.
Electronic devices and components Handling device 7 forms the carrying path 71 of electronic devices and components D, and sequentially to each step process unit 74 carrying electronic devices and components D that arrange along this carrying path 71.This carrying path 71 is by rotating disk (turntable) 72 and electronic devices and components holding device 1 and form.Rotating disk 72Shi is supported by the S. A. of carrying with motor 73 at center, and follows and carry the intermittent rotation predetermined angular with the driving of motor 73.Carrying is for example adopting direct drive motor (Direct drive motor) with motor 73.
Electronic devices and components holding device 1 arranges a plurality of in the mode that becomes the coordinations such as circumference and put in the outer peripheral edges of this rotating disk 72.Particularly, support arm 21 is fixed on to the outer peripheral edges of rotating disk 72, maintaining part 2 is supported by this support arm 21.Again, linear guides 31 is fixed on the outer peripheral edges top of rotating disk 72, and this linear guides 31 of pressing body 3 reasons supports and is positioned at the top of rotating disk 72, and lifting is arranged on the fixing fixed block of linear guides 31 with motor 4.
Each step process unit 74 that comprises winding unit 6 is to arrange along the outer peripheral edges of rotating disk 72.As other step process unit 74, selectivity disposes one or more in feeder, position correction unit, test contact device, indexing unit (marking unit), appearance inspection device, classification and ordination mechanism, defective products eduction gear 74a etc.
In present embodiment, at the back segment of winding unit 6, be a downstream of winding unit 6 on the hand of rotation of rotating disk 72, be provided with the defective products eduction gear 74a that the electronic devices and components D of bale packing does not discharge from electronic devices and components testing fixture.
The configuration space of maintaining part 2 equates with the anglec of rotation of a spacing of rotating disk 72.In other words, adopting direct drive motor is to make rotating disk 72 intermittent rotaries with the identical spacing of the configuration space with maintaining part 2.Pressing body 3 is arranged on the position consistent with the stop position of maintaining part 2.Again, processing unit is also arranged on the position consistent with the stop position of maintaining part 2.Moreover if the quantity of quantity >=transportation processing unit of the stop position of maintaining part 2, these quantity are also can quantity different, and also can there is the stop position of the maintaining part 2 that does not dispose transportation processing unit.
In this kind of electronic devices and components Handling device 7, keep maintaining part 2 adjoint turn-table 72 intermittent rotaries of electronic devices and components D, and sequentially move to, be set in circumference etc. and join locational stop position.If maintaining part 2 is positioned at stop position, the drive division that is present in the top of maintaining part 2 declines maintaining part 2.At the Bottom Of Descent of maintaining part 2, there is step process unit 74, electronic devices and components D is that implementation step is processed by the step process unit 74 of Bottom Of Descent.If step process finishes, pressing body 3 rises maintaining part 2, and rotating disk 72 makes maintaining part 2 move to next stop position.
When electronic devices and components D is paid in the step process unit 74 to beyond carrying belt 61, voice coil motor 37 is urged to electronic devices and components D on the platform of step process unit 74, and this pushing load is controlled as specified value.
The diagram of block of the formation of the control part 75 when Figure 13 means this kind of abnormal contact detection in electronic devices and components Handling device 7.Electronic devices and components Handling device 7 comprises rotating disk 72, electronic devices and components maintaining body and controls the control part 75 of each step process unit 74.This control part 75 comprises: notification unit 75a, and when abnormal contact detection, notice is contact extremely; And discharge control part 75b, discharge bad goods.
The abnormal contact of notification unit 75a notice.If the telltale (display) that this notification unit 75a is connected by communication line, loud speaker (speaker), chopping machine (printer) or Warning light (patrol lamp) etc. can be passed to the device of people's five senses, any one all can.Again, notification unit 75a also can comprise the memory device of storing data, and the situation that produces abnormal contact is recorded in memory device, when user produces, browses while requiring, and can notify abnormal contact.
Discharge control part 75b not by the electronic devices and components D bale packing that is extremely contacted with bag 62 in carrying belt 61, and make defective products eduction gear 74a discharge this bad goods.Figure 14 means the diagram of circuit of the action of this discharge control part 75b.
If extremely contact, in detection unit 53, be judged to be electronic devices and components D and extremely contact,, in step S11, notification unit 75a notice is abnormal to be contacted.Particularly, will show in the writing data into memory of abnormal contact, and export these data to telltale or chopping machine.Again, make loud speaker produce warning tones, Warning light is lighted.
Again, if be judged to be electronic component D in abnormal contact detection unit 53, extremely contact, discharge the action that control part 75b make electronic devices and components D just be inserted into the electronic devices and components holding device 1 in bag 62 and end.That is,, in step S12, by lifting is stopped the rotation with motor 4, thereby make the decline Halfway Stopping of maintaining part 2.Then, in step S13, by making pressing body 3 increase, discharge the application force of Compress Spring 23, thereby make maintaining part 2 increase with the hold mode of electronic devices and components D.
And then, discharge control part 75b the electronic devices and components D of abnormal contact is discharged from electronic devices and components Handling device 7.That is, in step S14, make a spacing of rotating disk 72 rotation, make to keep the maintaining part 2 of the electronic devices and components D of abnormal contact to be positioned at the top of defective products eduction gear 74a.Then, in step S15, maintaining part 2 declined and electronic devices and components D is departed from, thus, the electronic devices and components D of contact being extremely transferred to defective products eduction gear 74a.
Finally, in step S16, discharge control part 75b defective products eduction gear 74a is controlled, the electronic devices and components D of abnormal contact is discharged from electronic devices and components Handling device 7.
(effect)
As described above, the abnormal contact detecting method of present embodiment is to use motor 4 via the rod member 32 power Fr that makes to decline, maintaining part 2 to be acted on by lifting, and gives by 37 pairs of rod members 32 of voice coil motor the antagonism thrust Fopp that the antagonistic force Fcr suffered with rod member 32 for decline power Fr equates.And, to the resistance Fd producing when being contacted with carrying belt 61 and declining in response to electronic devices and components D, rod member 32 rises and detects for the relativism of voice coil motor 37, and by detecting this situation of rising of rod member 32, and detect the contact to carrying belt 61 midway that declines.
The method is to make voice coil motor 37 as a formation performance function of abnormal contact detection.; rod member 32 is applied to the antagonism thrust Fopp that the antagonistic force Fcr suffered with rod member 32 equates; thus, making the suffered comprehensive load of rod member 32 is 0 newton (newton), while the resistance Fd of induction electronic devices and components D is contacted with carrying belt 61 generation while declining.
With regard to making the suffered comprehensive load of rod member 32, be with regard to 0 newton, be preferably voice coil motor 37.Voice coil motor 37 can produce the thrust being directly proportional to current value, and this thrust is compared and can fine pitch be regulated with other motor.Therefore, easily precision makes antagonistic force Fcr consistent with antagonism thrust Fopp well, thereby can detect the less resistance Fd from soft material such as carrying belt 67 grades.
Thus, can be very simple and precision detect well and become contacting with the abnormal of carrying belt 6 of a reason of the bad generation of electronic devices and components D, thereby can more positively remove, there is the electronic devices and components D that produces bad possibility because of this abnormal contact.And then, can convert or and with giving to electronic devices and components D the voice coil motor 37 that suitable load utilizes in the step process in other step process unit 74, thereby without special mechanicalness formation.
Again, be after electronic devices and components D is inserted in bag 62 in the past, this bag 62 is moved to and check position, if confirm as bad goods, make bag 62 be back to the position of maintaining part 2, by maintaining part 2, pick up bad goods.Therefore, also need to make to comprise the step that the rotating disk 72 of maintaining part 2 carries out contrarotation and so on again.
On the other hand, in the abnormal contact detecting method of present embodiment, if produce the rising of rod member 32, can, by ending the insertion of electronic devices and components D to bag 62, make maintaining part 2 increase, thereby take out electronic devices and components D from bag 62.According to this abnormal contact detecting method, when generation electronic devices and components D contacts extremely, without the eliminating step via this electronic devices and components D in the past.
Therefore,, about the eliminating step of the bad goods relevant to abnormal contact, can shorten required time tremendously.Again, for other electronic devices and components D around carrying path 71, the timeliness impact that the step of getting rid of the bad goods relevant to abnormal contact can be caused fully reduces.
Moreover, also exist because abnormal contact factor in addition makes electronic devices and components D produce bad situation, so, can and by this test mode in the past.Again, if produce the rising of rod member 32, also can notify the contact of decline electronic devices and components D midway to carrying belt 61, by user, electronic devices and components D be taken out.
(other step process unit 74)
The abnormal contact of electronic devices and components D in the time of can detecting in this way the abnormal contact detecting method compared with the present embodiment of slight drag Fd from softness materials such as carrying belts 61 and be extremely suitable for detecting bale packing to carrying belt 61.But, while certainly also can be applicable to other step process unit to pay electronic devices and components D.
For example, Figure 15 is the partial enlarged drawing of feeder.Feeder shown in Figure 15 is electronic devices and components D to be supplied to the unit of electronic devices and components Handling device 7.This feeder comprises carrying path 81 and intermediate station 82.
Carrying path 81 is to swing in the direction that its bearing of trend tilts relatively, and till making electronic devices and components D move to terminal by this swing effect.Intermediate station 82 is in the electronic devices and components D on carrying path 81, to go to the discharging mechanism of maintaining part 2, and certainly carries path 81 and obtain electronic devices and components D, by parallel, makes electronic devices and components D be positioned at the stop position of maintaining part 2.This intermediate station 82 be with carrying path 81 terminal subtend configure.At the front end of intermediate station 82, be formed with the mounting surface 82a of electronic devices and components D.On intermediate station 82, in the mode towards mounting surface 82a, be formed with the barrier 82b that exceeds single order than mounting surface 82a.
In this feeder, barrier 82b has one makes to load the consistent function of posture in the electronic devices and components D of mounting surface 82a, but also produce occasionally following situation: when the electronic devices and components D of carrying path 81 and intermediate station 82 pays or during intermediate station 82 parallel, electronic devices and components D is stuck in or rests on barrier 82b.
Now, the highest part of electronic devices and components D is not stuck in when barrier 82b is above correctly positioned on mounting surface 82a and compares and uprise with electronic devices and components D.Therefore, take and be correctly positioned in maintaining part 2 that mounting surface 82a declines as prerequisite and extremely contact with electronic devices and components D declining midway.
Therefore, in electronic devices and components holding device 1, the resistance R that this abnormal contact producing in the decline process in response to maintaining part 2 causes, rod member 32 rises for voice coil motor 37 relativisies, thereby this rising detected by test section 38.Therefore, can detect the collision of electronic devices and components D and maintaining part 2, can extract out and may become bad electronic devices and components D because of this collision.
Again, Figure 16 is the partial enlarged drawing of position correction unit.This position correction unit comprises the guide member 83 of the posture of revising electronic devices and components D.In guide member 83, be formed with the hole 83a that approaches the pyramid shape that bottom becomes narrower.If electronic devices and components D is inserted in the hole 83a of guide member 83 by maintaining part 2, the posture of electronic devices and components D changes in connection with the inner wall shape of hole 83a.By causing this attitude change, thereby position correction unit is modified to desired posture by electronic devices and components D.
In the time of in electronic devices and components D is inserted into this guide member 83, adjust in advance the degree of depth of inserting electronic devices and components D.In other words, in conjunction with the size of electronic devices and components D, predetermine the slippage of maintaining part 2.Yet, will produce following situation once in a while: the deviation of the posture being kept by maintaining part 2 due to the size of electronic devices and components D or the inequality of thickness or electronic devices and components D etc., cause guide member 83 extremely to contact with electronic devices and components D.
Now, for electronic devices and components D being inserted into than in its narrow aperture of size, and the large abnormal resistance R of common resistance producing while producing the attitude change of comparing the inwall that uses guide member 83.
Therefore,, in electronic devices and components holding device 1, by lifting motor 4, via rod member 32, decline power is acted on to maintaining part 2.In this decline power, the common resistance producing while adding in advance the attitude change of the inwall that uses guide member 83.By voice coil motor 37, to rod member 32, give the antagonism thrust that the counteraction suffered with rod member 32 for this decline power equates again.
Then, the resistance R that the abnormal contact producing in the decline process in response to maintaining part 2 causes, rod member 32 rises for voice coil motor 37 relativisies, and detects this rising by test section 38.Therefore, can detected electrons components and parts D and the collision of guide member 83, extraction may become bad electronic devices and components D because of this collision.
Again, Figure 17 is the partial enlarged drawing of test contact device.Thereby test contact device is the device that makes electronic devices and components D energising test electrical characteristics, and in inside, comprises and exposing the socket (socket) 84 of electrode for energising.
In this test contact device, also can produce following situation once in a while: electronic devices and components D is being inserted into socket 84 when interior, electronic devices and components D is stuck in or rests on the madial wall of socket 84.
Now, the highest part of electronic devices and components D be correctly inserted into socket 84 and compare when interior and uprise.Therefore, take and be correctly inserted in socket 84 maintaining part 2 that declines as prerequisite and extremely contact with electronic devices and components D declining midway.
Therefore, in electronic devices and components holding device 1, the resistance R that this abnormal contact producing in the decline process in response to maintaining part 2 causes, rod member 32 rises for voice coil motor 37 relativisies, thereby detects this rising by test section 38.Therefore, can detected electrons components and parts D and the collision of maintaining part 2, thereby extract out, may become bad electronic devices and components D because of this collision.

Above embodiments of the present invention are illustrated, but can in the scope that does not depart from invention spirit, implement various omissions, replacement, change.And this embodiment or its distortion are contained in scope of invention or spirit, and be contained in the invention recorded in claim and impartial scope thereof.
For example, in the present embodiment, take and use servomotor to be illustrated as example by the situation of motor 4 as lifting, but as motor, can apply stepper motor (stepping motor) etc. known any one.Again, as maintaining part 2, adopting adsorption mouth is that example is illustrated, but the also chuck mechanism of configurable electrostatic adherence mode, Bai Nuli sucker (Bernoulli chuck) mode or mechanicalness clamping electronic devices and components D.
And then, can comprise Compress Spring 23,36 both, also can comprise any one, but also both all do not comprise, and produce accordingly with which the antagonism thrust Fopp that the antagonistic force Fcr that is subject to rod member 32 equates.; so-called decline power Fr comprises the power that elastic force difference that the power, the opposing Compress Spring 23 that only make the maintaining part 2 without Compress Spring 23,36 decline only make power that maintaining part 2 declines or opposing Compress Spring 23,36 only makes maintaining part 2 decline, and antagonistic force Fcr is the meaning corresponding with this decline power Fr.
Again, the control part 5 of electronic devices and components holding device 1 both can be included by electronic devices and components holding device 1, also can make the included control part of electronic devices and components Handling device 7 75 carry out same processing.
And then having enumerated the situation that disposes various step process unit 74 in a rotating disk 72 is example, but as carrying mechanism, both can be straight line mode of transport, again, also can form a carrying path 71 by a plurality of rotating disks 72.Various step process unit 74 is not limited to described kind, can replace with various step process unit 74, also can suitably change configuration sequence.
