Description

Adjust method and apparatus and electronic component conveying device that electronic component enters pipe

Technical field

The present invention relates to adjust the method and apparatus that electronic component enters pipe.The invention still further relates to a kind of device that electronic component enters pipe of adjusting, it can be used for taking out element from the pipe of adjusting.

Background technology

Electronic component generally will be adjusted and enter in the pipe, and pipe is made with the antistatic hardening plastics usually and had the section of rectangle substantially, thereby the favorable mechanical protective effect is provided, especially can delivering electronic components.In some cases, the section configuration specialized designs of pipe is to be fit to the type of the element of being adorned, such as the shape that is fit to element and the distribution of pin.When adjusting, element slides in the pipe one by one, and one is leaned on a ground to be contained in the inside.Each end of pipe seals to prevent that element from dropping out with coarse block usually.

In order to carry out subsequent treatment,, electronic component must be taken out from pipe such as by p-wire or printed circuit board (PCB) mounting equipment.This operation is normally undertaken by feed arrangement, and electronic component is transported to certain position after pipe takes out, be sent to therefrom then, as p-wire or printed circuit mounting equipment.

Most of devices of prior art utilize gravity that element is skidded off from pipe.Earlier one in two blocks at closed tube two ends is taken off.The pipe that element will be housed is put into then, and normally flatly, receiver can take out pipe one by one from receiver.By the mechanism of more complicated often the blind end of probe tube is raised, electronic component is slided towards the openend of pipe.Yet, because element preferably horizontal positioned be sent to another device, must proofread and correct its orientation when element leaves pipe.Therefore usually element is slided on the bending delivery device from pipe, but bending delivery device delivery element is to desired position.

There are some shortcomings in these one type of prior art syringe.Often very complicated thereby its processing speed of the mechanism that pipe one end is raise is restricted.And the bending delivery device is very accurate thereby its manufacturing cost is very high.They are the very accurate guide rail of section configuration normally, and electronic component slides at the effect lower edge of gravity guide rail.Along with the quickening of production and processing wire rate and reducing of component size, must process these guide rails with very high precision, to guarantee element essential flow and precision are arranged when sliding on guide rail.When the component type of device processing changes, new guide rail must be installed, this often needs the very long adjusting time, and device can not be worked during this period.

In order to overcome these shortcomings, the feed arrangement of some prior art has adopted pushing mechanism, makes and can take out element in pipe maintenance level.Pipe is generally aimed at linear conveyer, makes the element of taking-up arrive the position that can be sent to processing line.Though these devices do not need to raise the mechanical device of pipe, also without any need for the mechanism in correcting element orientation, as the guide rail of bending, very complicated usually and its speed of employed pushing mechanism often is restricted.

U.S. Patent application US 2002/00667980 has introduced a kind of feed arrangement, and its pushing mechanism comprises the steel band that inserts pipe by pipe one end, with other end pushing member tomorrow.This mechanism is very complicated and accurate, mainly is because must accurately control the motion of pushing mechanism, and synchronous as the speed that moves the processing line that takes out element with follow up device.And, before the receiver of pipe being put into feed arrangement, must remove the block at pipe two ends, for each pipe of handling, this need carry out extra operation.

U.S. Pat 4770565 has been introduced a kind of device, and wherein electronic component takes out from its feed tube by suction.One end of feed tube inserts in the adapter, and the opposite side of adapter is connected to the tubulose conveyer, and element is delivered to the position that the equipment that can be placed takes out.Air is pumped in the adapter along the direction of conveyer, produces parital vacuum in the feed tube exit.So element is sucked into adapter from pipe.Yet the major defect of this system is to be difficult to control to take out element, especially regularity of Qu Chuing and speed from feed tube.Is to be given birth to by the compressed air miscarriage of another outlet of adapter element from the parital vacuum of its pipe sucking-off.The power of vacuum degree after compressed air flows through and taking-up element can not accurately be controlled by this way.And in adapter, the parital vacuum after element flows from air moves to the overpressure zone of the conveying air of nozzle back.Therefore element must be subjected to the strong turbulent region that disturbs through making its linear displacement, and this will increase the danger of obstruction greatly.And for every type feed tube and every type the special shape and size that change adapter of element needs.If handle the dissimilar elements that adjustment enters different feed tubes continuously, all must load onto new adapter at every turn, even load onto new conveyer possibly with this device.

U.S. Pat 5368193 has been introduced a kind of container that is used for electronic component, comprises spiral receiver.The document has also been introduced a kind of feed arrangement that adapts, and can be blown into air by the opening that is provided with specially to take out element on container.Yet the use of this device is very limited, because will be suitable for this kind container, and it is corresponding to non-industrial standard.

Summary of the invention

Therefore an object of the present invention is to propose a kind of method and apparatus that takes out electronic component, there is not the shortcoming of the method and apparatus of prior art in it.

Another object of the present invention be propose a kind of from the automatic machining line delivering electronic components and adjust the method and apparatus that element enters pipe.

These purposes are to realize by the method and apparatus of the feature with corresponding independent claims.Dependent claims has further provided preferred embodiment.

Particularly, these purposes are to realize that by a kind of method that electronic component is inserted the linear tube be used to carry wherein, described electronic component inserts described pipe by pneumatic mechanism in the negative pressure that described pipe one end produces.These purposes also enter the device of the linear tube that is used to carry and realize from the device of the processing line output electronic component that comprises this adjusting device by a kind of electronic component of adjusting, described adjusting device comprises pneumatic system, can produce negative pressure at pipe one end, make electronic component insert pipe.

Embodiment

In a preferred embodiment, device of the present invention is a kind of withdrawing device that is attached in the electronic component feed arrangement, feed arrangement be designed to can with around the processing line around the circular conveyer 9 as test and/or adjust line work (Fig. 1 and 2).Feed arrangement takes out electronic component 8 and makes it can be sent to circular conveyer 9 from pipe 7.The peripheral equipment of circular conveyer 9 has element recipient such as suction nozzle 90, and other workbench 99 that is used for taking off element 8 and will be transported to processing line figure 2 illustrates the part of these workbench as test, mark and/or adjustment workbench.

The same with other workbench 99, feed arrangement preferably is fixed on the support plate 10, and support plate can comprise and be designed to the securing member (not shown) that can work with the securing member on the fixed head (not shown), fixed head preferably be placed in circular conveyer 9 below.So different processing stationary table can be constituted described processing line on the fixed head (not shown) around the circular conveyer 9 by modular manner.The position of the relative conveyer 9 of each processing workbench is accurately determined by the accurate position and the size of respective fixation part.

In a preferred embodiment, feed arrangement of the present invention comprises conveyer, and preferably the straight line conveyer 5, is used for carrying the electronic component 8 that takes out from pipe 7 to the position that can be drawn by the suction nozzle 90 of circular conveyer 9.Straight line conveyer 5 can be a vibratory conveyer, and electronic component 8 moves on vibratory conveyer under the effect of electromagnetism or piezoelectric vibrator 55, or partially enclosed at least guide rail, by pneumatic mechanism electronic device is moved.Straight line conveyer 5 can comprise the bottom 50 that is fixed on the vibrator 55, and also is provided with guide rail moving with the guiding electronic component on vibrator 55.The section configuration of guide rail preferably is suitable for the component type that will carry.Interior section configuration best and pipe 7 is similar.Bottom 50 is covered to prevent that element from dropping out because of carelessness from guide rail by lid 51.According to this make, the downside of lid 51 can also be formed with the section configuration that helps induction element.

The withdrawing device of the present invention of electronic component 8 is arranged near the relative end of straight line conveyer 5 and circular conveyer 9 in the desirable empty pipe 7.Withdrawing device is arranged by this way, when taking out electronic component 8, will get empty pipe 7 and aim at straight line conveyer 5.So the electronic component 8 that takes out from pipe 7 is introduced directly into straight line conveyer 5.

Withdrawing device comprises bearing 45, when taking out electronic component 8, preferably by mechanical means such as pipe 7 being fixed on the bearing 45 with forcing press 4, forcing press 4 comprises the collet 41 that is connected to linear actuators 40, is used for compressing pipe 7 but can cause damage to it.

Comprise the pliers 3 of two

clamps

31,32 that can move by linear actuators 30 can clamping tube 7 end relative with straight line conveyer 5.Size forms in the inboard of

clamp

31,32 greater than the gap of pipe 7 sizes.This gap is partially filled at least deformability and compressible material such as airtight foam 35, and when pliers 3 was brought together into pipe 7, foam 35 was consistent with the outline of pipe 7.Pliers 3 is connected to the pneumatic system (not shown) by the pipeline 39 that is arranged on down clamp 32.

Feed arrangement preferably includes receiver, and best and withdrawing device is arranged in parallel, and makes it possible to receive some pipes 7 that electronic component 8 is housed.Receiver can be made of two guide rails of vertically arranging substantially 6, guide rail 6 is arranged to can remain in respectively by its U-shaped guide rail section configuration pipe 7 ends of receiver, therefore can prevent that pipe from moving horizontally when allowing pipe 7 vertically to slide.The mechanical device (not shown) is sent to withdrawing device with pipe 7 from receiver.Recover 66 can be seen in Fig. 2, can be arranged on the opposite side of withdrawing device, in order to receive empty pipe.

Be equipped with and be laminated in the receiver by the pipe 7 that feed arrangement is introduced the electronic component 8 of processing line.In order to prevent that electronic component 8 from dropping out, with coarse block sealing, block can be made of the foam or the plastics that insert pipe 7, or crosses the continuously connected fastener of pipe 7 along the direction that is orthogonal to pipe 7 longitudinal axis usually at the two ends of pipe 7.Pipe 7 is being put into before the receiver, removed the block of at least one end of pipe, using manual manipulation usually, taking out to allow electronic component 8.Pipe 7 is sent to withdrawing device from receiver one by one then, to empty electronic component wherein.

Fig. 3 a shows the details of receiver and pipe 7 is sent to the part of the mechanism of withdrawing device from receiver.Support is in the lower end of guide rail 6 of pipe 7 ends of horizontal plane opens, and passes through with the pipe 7 under allowing.Pipe 7 is remained in the receiver by at least one baffle plate 60.The actuator (not shown) makes that baffle plate 60 can be around its rotational (Fig. 3 b), thus the pipe under discharging, so can shift beneath pipe onto bearing 45 towards the direction of withdrawing device with the mechanical device (not shown).Be in when pipe 7 behind the axis of straight line conveyer by collet 41 fix in position, the bottom shape of collet 41 can guarantee that preferably pipe 7 aims at the straight line conveyer, even recoverable pipe 7 makes it aim at the straight line conveyer.

Pliers 3 is brought together into the end (Fig. 4) of pipe 7.As shown in Figure 5, the airtight foam in the

clamp

31,32 35 closely surrounds the outline of pipe 7.So in the

clamp

31,32 not the gap portion of filled and process 35 constitute air-tight chamber 36, this air-tight chamber is connected to the pneumatic system (not shown) by pipeline 39.

Yet the those skilled in the art should know and can also seal pipe 7 chamber 36 on every side with foam-expelling 35 outer alternate manners.Make the section configuration of clamp meet the outline of pipe 7 fully such as expecting, and can be provided with the plastic material packing ring with further raising sealing.Yet Fig. 6 shows the advantage of introducing previously that the preferred embodiment of the present invention proposed a solution.Since the deformability and the compressive characteristics of foam 35, the dissimilar electronic components that can use same pliers 3 to take out in the pipe that profile differs greatly.Foam 35 both can make self cooperate the pipe 7 that having of no pin electronic element 8 is ellipse or rectangular cross section substantially had been housed, but also adaptive zone pin electronic element 8 ' pipe 7 ' shape.

When pliers closed up, foam 35 had better not cover the whole end of the pipe 7 that is arranged in chamber 36.In order to take out element 8 from pipe 7, the most handy pneumatic system is continuously sent into chamber 36 with compressed air by pipeline 39, thereby produces overvoltage.Because it is not airtight clogging the block 70 of pipe 7 ends, so the overvoltage that produces in chamber 36 propagates into pipe 7 from the end that is arranged in chamber 36, towards the openend pushing member 8 of the pipe of aiming at straight line conveyer 57.Therefore element 8 and is sent on the straight line conveyer 5 one by one because the overvoltage that produces in the chamber 36 is discharged from pipe 7 in the mode of continuous flow.Yet the those skilled in the art should know and it will also be appreciated that within the scope of the invention by other method element 8 is discharged from pipe 7 one by one, such as utilizing compressed-air actuated continuous short pulsation.

When the element in the pipe 78 is got sky fully,, open pliers 3 and mention collet 41 such as after applying overvoltage a period of time.Then pipe 7 is withdrawn from the following recover 66 of bearing 45 with the mechanical device (not shown).New pipe 7 can be delivered to withdrawing device from receiver then.

The function of feed arrangement is preferably full automatic and controlled by the control system (not shown).Therefore whether all parts, especially actuator and the pneumatic system of the best control device of control system, and to handling from the signal of each detector, probe or other control assembly make it possible to testing fixture and correctly work and find contingent fault.The concentrate control automatically and the management of all working process make that the operating rate of feed arrangement can optimization, and this mainly is because the complete synchronous coordination work of all parts.

According to the present invention, withdrawing device uses pneumatic mechanism to take out element 8 from pipe 7, makes pipe can remain on horizontal level in the whole operation process.Utilize the withdrawing device of gravity generally must use complicated mechanical devices to raise pipe, and withdrawing device of the present invention needn't adopt this class complicated mechanical devices.Compare with the employed propulsion plant of prior art withdrawing device, the mechanical device that is used for implementing the inventive method can take out element from the pipe of horizontal positioned, thereby it is simple and firm more.

Especially utilize the device of gravity to compare with one type of prior art syringe, apparatus of the present invention of utilizing pneumatic mechanism to take out element can further improve speed.

Another advantage of withdrawing device of the present invention is to allow element 8 two-way flow in pipe 7.

It is more and more little that the size of electronic component becomes now.And they are laterally placed often, and promptly its maximum size is perpendicular to the longitudinal axis of pipe.Therefore these two factors can reduce the crosswise fixed power of element in pipe, make element crooked slightly.Therefore usually such situation can take place, promptly certain electronic component too tilts, and makes the one angle block the inboard of pipe, and blocks the element of back.In this case, can not deal with problems, because the element that clogs can block tightlyer in pipe along the extra power that the pipe Way out is applied on the element.

The withdrawing device of prior art generally can not address this problem automatically, but needs: the empty pipe of part is taken off from device, manually change the element that clogs, then pipe is inserted device again.Therefore this method need be carried out extra work, but also can not find to exist the element that clogs, thereby might to clog thinking of element be that empty pipe is thrown away with having.

According to a preferred embodiment of the invention, pneumatic system not only makes compressed air to introduce in the chamber 36 by pipeline 39, but also can sucking-off air wherein.Therefore chamber 36 in, form negative pressure and propagate in the pipe 7, so can be towards the direction attraction electronic component 8 of pliers 3.Therefore make the element that clogs when taking out, can redirect along the direction of pliers 3.By compressed-air actuated quick pulsation and suction operation are hocketed, pneumatic system makes the element 8 in the pipe 7 produce reciprocating motion.A little alternating movement generally just is enough to solve most of obstructing problems.Can recover then to take out operation, compressed air is introduced in the chamber 36 in a continuous manner again, all be taken out until element.

Therefore, withdrawing device according to the present invention preferably includes the controlling organization (not shown), as optical pickocff, is used for detecting the existence of electronic component 8 in the pipe 7 and element is sent to situation on the straight line conveyer 5 from pipe 7.The information that these controlling organizations send is delivered to the control system of device.Also there is electronic component 8 in the pipe 7 but do not have element when pipe 7 is sent to the information of straight line conveyer 5 when control system received in the taking-up stage, control system sends instruction makes element produce reciprocating motion according to above-mentioned principle to pneumatic system, rebuilds in chamber 36 then and takes out the necessary pressure of element.If pipe does not get clogged, that is,, controlling organization is sent to straight line conveyer 5 from pipe 7 if detecting element, and the normal taking-up of element 8 is proceeded.Under opposite situation, control system makes element begin a series of new alternating movements.

According to a kind of variant embodiment of the present invention, forcing press 4 is fixed on the vibrational system (not shown), and vibrational system directly or indirectly is fixed on the support plate 10.Preferably pipe 7 is clamped in then between the collet 41 and another collet (not shown) that also is fixed to vibrational system of forcing press 4, the height of this collet upside height with bearing 45 upsides substantially is identical.Therefore vibrational system makes pipe 7 can produce vibration near the end of straight line conveyers 5, preferably fast and amplitude very little.If electronic component 8 clogs when taking out, vibrational system is switched on, along the vibration-direction vibration that is parallel to element 8 in the pipe 7.This vibration of pipe 7 ends can be removed the obstruction of issuable electronic component 8 between the inlet of the outlet of pipe 7 and straight line conveyer 5.

According to the above-mentioned embodiment of the invention, described withdrawing device is particularly suitable for taking out conditioned electronic component from vertical side all is the pipe of sealing on its whole length, this pipe 7 and 7 ' the example of section configuration shown in Fig. 5 and 6.Because the pipe of sealing is airtight,, make it possible to control well the motion of the electronic component that will take out in chamber 36 so the overvoltage and/or the negative pressure that form can be propagated best on its whole length.

Yet some pipe that is used for adjusting electronic component is that part is opened wide at least, and promptly section configuration is discontinuous at least a portion of its length.Show the pipe 7 of opened upper end such as Fig. 7 " section configuration.Because these pipes are not airtight on its whole length, the pressure differential that is produced in the chamber 36 of pliers 3 by pneumatic system can only be transmitted to first lateral openings place that corresponding air stream is run into effectively, control effectively to being positioned at this opening element in addition thereby hinder.Can remedy this defective though be ejected into the pressure of air in the chamber 36 by raising, make element towards the pipe of relative pliers 3 outlet motion, make under the situation that element redirects must be towards pliers 3 air-breathing, this defective may remedy hardly.

Be suitable for the pipe 7 that opens wide from the pipe that opens wide such as top so Fig. 8 and 9 illustrates " the preferred embodiment of apparatus of the present invention of the conditioned electronic component of taking-up.This withdrawing device preferably includes the mechanical device that makes that one or more openings of pipe at least can be partially enclosed, thereby guarantees that pipe has enough air-tightness to take out wherein electronic component with the method according to this invention effectively.

Parts identical in Fig. 1 to 9 are represented with identical reference number, unless specified otherwise.

According to the variant embodiment shown in Fig. 8 and 9, be used for partially enclosed at least pipe 7 on " mechanical device preferably include top cover 46, when pipe 7 " was put into bearing 45 to take out element 8 wherein ", top cover 46 was positioned at pipe 7 "." the length of entire top between collet 41 and pliers 3 that the length of top cover 46 preferably is enough to cover pipe 7.In order further to improve pipe 7 " sealing, the lower surface of top cover 46 is preferably covered by liner 47 to small part, the gastight material such as the rubber of liner 47 usefulness softness are made.Yet liner 47 preferably has enough rigidity liner and pipe when preventing to put down top cover 46 to give 7 " in electronic components 8 " contacts, and this can hinder the taking-up of electronic component.

Top cover 46 preferably movably and its motion by the control system control of device.Top cover 46 can vertically be moved by linear actuators (not shown) such as pneumatic booster or electromagnetic actuators, on pipe 7 " when being placed into the extracting position of bearing 45, this linear actuators is depressed into pipe 7 with the power of being scheduled to top cover 46 ".Preferably automation of the motion of top cover 46, and coordinate mutually with the motion of pliers 3 and collet 41, make and taking out in the above described manner on the element 8 " these three parts can close up and/or transfer to pipe 7 simultaneously before ".After pipe 7 " in electronic component 8 " is got sky, mention top cover 46, open pliers 3 simultaneously and rise collet 41.Can will get empty pipe 7 then and " withdraw bearing 45, change the pipe of filling, and repeat above-mentioned steps.

According to the above-mentioned variant embodiment of introducing by example, be used for partially enclosed at least unlimited pipe 7 " mechanical device comprise the top cover 46 that is arranged between pliers 3 and the collet 41.Yet, it will be understood to one skilled in the art that the machinery or the non-mechanical top cover that also can use other form within the scope of the invention.The those skilled in the art it is also recognized that the sealing that can guarantee to open wide pipe with other mechanical device.Such as expecting that the size that changes collet 41 makes it cover the other end of the top of pipe until pipe from pliers 3, the size that perhaps can change the last clamp 31 of pliers 3 covers it and opens wide pipe until collet 41, perhaps these two kinds of methods can be combined.

Within the scope of the invention, withdrawing device can also be used to taking out electronic component from the pipe of lower open, such as placing on the bearing 45 that opens wide pipe with soft gastight material to small part covering when taking out element; The pipe that perhaps can open wide from the side takes out electronic component, such as inserting the bearing 45 with appropriate section shape fully or utilize the special cover plate of vertically placing to cover one or two side of opening wide pipe by opening wide pipe.According to the size and the position of pipe opening to be processed, it will also be appreciated that any compound mode of above-mentioned solution within the scope of the present invention certainly.

In previous examples, withdrawing device of the present invention can take out electronic component from a pipe.The those skilled in the art should easily recognize to modify withdrawing device of the present invention and make it take out electronic component simultaneously from several parallel pipes.This device is provided with several pliers 3 and several collets 41 with the fixing pipe of institute's number required.Pliers and the collet that can fix several pipes simultaneously can also be set.So pliers has and the airtight single pumping chamber that links to each other of the whole pipes that clamped, or several chambers that link to each other with each pipe respectively, from each pipe, take out electronic component thereby make it possible to control.

For the withdrawing device that can handle several parallel pipes, feed arrangement of the present invention can also receive the electronic component that takes out from these pipes makes them can be used in one or several processing lines.So this feed arrangement is provided with the parallel lines conveyer or the single conveyer with some inlets and an outlet of respective number.

According to another preferred embodiment, the present invention can be used for from automatic machining line output electronic component 8 and pipe 7 it is adjusted.According to this embodiment, above-mentioned withdrawing device and feed arrangement are transformed into adjusting device and conveying device respectively.Conveying device of the present invention is collected the electronic component 8 crossed by the processing line processed and they is inserted pipe 7, to electronic component adjustment it can be transported and/or store more easily in pipe usually then.

According to this embodiment and with reference to figure 1, such as being placed into by circular conveyer 9 on the straight line conveyer 5 of conveying device, conveying device is delivered to electronic component and conveyer 5 is relative and preferably by the fixing pipes 7 of pliers 3 from its set-point through electronic component 8 that the automatic machining line test processes is crossed.As previously described, the element 8 on the straight line conveyer 5 is such as moving by vibration or by means of pneumatic mechanism.

According to the present invention, the electronic component of being carried by straight line conveyer 58 is when arriving the inlet of the pipe of aiming at straight line conveyer 57, in the negative pressure suction pipe 7 that is produced in pipe 7 by pneumatic mechanism.With reference to figure 4,, close up pliers 3 and the most handy pneumatic system and continuously deflate from chamber 36, thereby in chamber 36, produce negative pressure or vacuum by pipeline 39 for element 8 is inserted pipe 7.Because it is not airtight clogging the block 70 of pipe 7 ends,, thereby element 8 is drawn onto the pipe 7 from the straight line conveyer so the vacuum that produces in chamber 36 propagates into pipe 7 until the other end from the end that is arranged in chamber 36.So element 8 transmits and inserts in the pipe 7 by the vacuum that produces the chamber 36 from the straight line conveyer one by one.

After the pipe of aiming at straight line conveyer 57 is filled element 8, open pliers 3 and forcing press 4 and pipe is moved to the stacker (not shown).Get empty adjustment pipe 7 and preferably leave in the receiver that constitutes by two guide rails 6, new empty pipe can be taken out from receiver then, it is aimed at straight line conveyer 5 and by closing up pliers 3 and forcing press 4 is fixed.So can electronic component 8 be inserted in the pipe of just having aimed at 7 according to the top principle of introducing.

As previously described, output of the present invention and/or feed arrangement preferably include the controlling organization (not shown), as optical pickocff, are used for detecting in the pipe of aiming at straight line conveyer 57 whether have electronic component 8.When device of the present invention was used for output and adjusts element, controlling organization preferably can also detect element is sent to situation the pipe 7 from straight line conveyer 5.The information that these controlling organizations send passes to the control system of conveying device.Do not fill electronic component 8 but do not have element when straight line conveyer 5 is sent to the information of pipe 7 when control system receives pipe 7, control system sends instruction and produces reciprocating motion to the principle that pneumatic system makes element introduce according to the front, rebuilds in chamber 36 then element is sucked pipe 7 necessary vacuum.If pipe does not get clogged, that is,, controlling organization is sent to pipe 7 from straight line conveyer 5 if detecting element, and the normal insertion of element 8 is proceeded.Otherwise control system makes element begin a series of new alternating movements.

Usually, conveying device of the present invention preferably has the feature identical with withdrawing device with the feed arrangement of introducing previously respectively with adjusting device.Yet the difference between these two aspects of the present invention is that when element 8 was collected and inserts pipe 7, it was carried in opposite direction on straight line conveyer 5.Another difference is, negative pressure mainly produces in the chamber 36 of adjusting device, and in order to element 8 is sucked pipes 7, and overvoltage mainly produces in the chamber 36 of withdrawing device, is used for releasing elements 8 in the middle of pipe 7.Also have a difference to be, when device of the present invention was used for insertion element to pipe, the pipe that leaves in the receiver was empty adjustment pipe, and the adjustment pipe of these skies can be aimed at the element of packing into straight line conveyer 5 one by one.Also have a difference to be in addition, when device of the present invention is used for taking out and sends electronic component 8 to, getting empty pipe 7 is moved in the recover shown in Figure 2 66, and when device of the present invention is used for output and adjusts electronic component 8, preferably recover is replaced with stacker, horizontal stacking is wherein one by one for the pipe of filling.

It will be understood to one skilled in the art that, according to the present invention, if the cover plate 46 of " in adjustment element, conveying device so of the present invention preferably includes partially enclosed at least pipe 7 " is introduced as earlier in respect of figures 9 must be at the pipe 7 that opens wide to small part.

The those skilled in the art it is also recognized that conveying device of the present invention can be used for insertion element in several parallel pipes, and that is introduced above being similar to takes out element from several pipes.

According to a variant embodiment of the present invention, described automatic machining line comprises two devices of the present invention.First device takes out the element of undressed processing and they is delivered to processing line from the pipe of adjusting element, and second device collected element that processed crosses and it is adjusted to enter from automatic machining line and adjust the pipe 7.These two devices preferably are identical basically, its as the function of feed arrangement or conveying device preferably by the control system of each device being programmed and making that slight modification mechanically determines.Mechanically main difference part is the efferent duct gatherer between feed arrangement and the conveying device, and simple receiver 66 is used for feed arrangement, and the pipe stacker is preferably used in adjusting device.This be not both because the blank pipe that takes out from withdrawing device when operation, do not need too careful, and must careful operation from the pipe of filling element of adjusting device output, such as, must remain on horizontal level always and from pipe, drop out to prevent element.
