Description
Technical field
The present invention relates to by the conveying of vibration to electronic component.The invention particularly relates to a kind of method by vibration, element being transported to drainage area from memory storage, this memory storage contains the element of bulk form (Sch ü ttgut).In addition, the invention still further relates to a kind of element-feeding mechanism, be used to provide the element of separation, and especially for automatically to assemble with component carrier in automatic assembling machine, provide the electronic component of separation.
Background technology
When component carrier mechanically assembles with (electronics) element, element to be processed being supplied to the operation of pickup or placement location, is typical assembling process in automatic assembling machine.The supply of element is carried out like this at this, namely these elements have the spatial orientation of explication, from the supply of definition or take-off location fast and reliably picked up by the assembly head of automatic assembling machine, and can be placed on relevant component carrier with the locus preset and orientation pendulum so that.
In order to ensure reliable supply or the transmission of element, these elements are packaged in so-called component tape.Then this component tape is directed on automatic assembling machine step by step by special element-feedway, and the element being therefore arranged in this component tape one by one and be transferred to supply position or take-off location with the locus of definition.Certainly, be complicated by component package in this component tape and costliness.In addition, this component tape material must be used as waste disposal after taking off element.
In order to avoid packaging and the above-mentioned garbage problem of this complexity, it is known that apply so-called vibratory conveyer, element to be processed can be separated into the form of bulk and transport by it.Certainly this needs especially huge machine cost, these elements can not only be separated, but also they is taken in the locus and orientation preset.In order to reach this point, vibratory conveyer constructs usually like this, namely by the guiding device of machinery, it is usually also referred to as " dividing plate " of machinery, and such as, by simple sensor, grating, by the location of element, classification like this, makes to only have " available element " to be directed in supply or take-off location particularly by track or passage.But due to the component tolerances existed in a manufacturing process, continuous print supply can not be guaranteed enduringly in practice, and if automatic assembling machine speed and supply distance longer time, these elements often can not as continuous print assembling run required by paying so soon.
By the known a kind of vibratory conveyer of document WO 2010/089290 A1, element can move so targetedly by be superimposed upon (the mechanical dividing plate) on three different direction in spaces of this vibratory conveyer by vibration, they reliably can be separated and transfer to supply range in the pick-up area of the definition on the supply range that presets, the assembly head by automatic assembling machine can pick up from this supply range simply.But in the vibratory conveyer that this is known, supply or take-off location can not carry out explication for each element.Therefore, the assembly head by automatic assembling machine to receive before electronic component must by special photographic camera to be optically to the pick-up area on the surface preset in the element that provides detect, and assess its accurate locus by the data processing unit being connected on this back of camera.Therefore its consequence is that photographic camera positions relative to pick-up area, and this photographic camera is directly or by mirror deflection ground seen from above to pick-up area.Then by the known location of photographic camera, the place of the element detected by photographic camera is determined.
That those have taken out and must should discard when assembling and interrupting to the element in supply or pick-up area by vibrating transportation carrying on section from bulk form-memory storage for the shortcoming of this known vibratory conveyer the electronic component be made up of bulk form.If change component carrier to be assembled or electronic product to be generated and (at least temporary transient) no longer needs the element of correlation type, then this interruption is necessary.In order to avoid this of element is discarded, in principle it is contemplated that acetyl send the part classification be arranged on conveying section back to bulk form-memory storage.But because the size of element is usually very little, and the danger being not intended to mix may be had due to dissimilar element, so it is insignificant that this classification is sent back to, therefore not adopt in practice.
Summary of the invention
The object of the invention is, the element separated by bulk form element is reliably provided, the number of elements (compared with known vibratory conveyer) must discarded during to be reduced in and to change element.
This object is achieved by the content of independent claims.Describe favourable embodiment of the present invention in the dependent claims.
By the first angle of the present invention, describe a kind of method by vibration, element being transported to drainage area from memory storage (Magazin), this memory storage contains the element of bulk form.Described device has (a) storing apparatus for memory storage; (b) channel architecture, it extends and can mechanically be coupled with oscillatory system between storing apparatus and drainage area; And (c) packaged unit, it to be arranged in channel architecture and can to move between open position and detent position, wherein channel architecture is closed in the detent position of packaged unit (256), drainage area (162) is delivered to from storing apparatus (152) to stop other element (495), wherein channel architecture (154) is vacated or is opened in the open position of packaged unit (256), is delivered to drainage area (162) to make other element (495) from storing apparatus (152).
Described device is based on following cognition, and namely these elements can be carried through relatively long path by vibratile channel architecture, thus eliminate the spacing preset between memory storage and drainage area.Because according to the length of channel architecture, except memory storage, this channel architecture is also the stowage arrangement (Reservoir) of element, so be provided with packaged unit by the present invention, channel architecture can be closed by this packaged unit.This point also creates such possibility, if namely the element (it is delivered to drainage area by described device) of particular type need not be used for assembling element carrier again, then whole device preferably removes from the element-feeding mechanism with oscillatory system together with the memory storage of at least local clearing, and temporarily leave in warehouse (L nge), until again need such element subsequently.
By the present invention, the effect of described packaged unit is, if packaged unit is arranged in detent position or make position, does not then have element can come off from channel architecture, or does not have other element or contaminate particulate can infiltrate in channel architecture.Therefore, it is possible to left in warehouse by described device chronically, and need not worry that the element of stowage arrangement and other type be made up of channel architecture and memory storage and/or dirt mix.
The length of channel architecture can be selected like this, namely can eliminate (a) storing apparatus or the spatial separation preset between memory storage and (b) drainage area.Therefore, described device can be applied in element-feeding mechanism, and these elements are supplied to drainage area by vibration, and therefore they can come automatically to assemble with component carrier by assembly head from this.At this, this element-feeding mechanism can have the bulk identical or at least similar with known element-feeding mechanism, it by the element transmission that is packaged in component tape on take-off location, and this element can be picked up by assembly head from this take-off location equally, automatically to assemble with component carrier.
In addition, the advantage of relatively long vibratile channel architecture is that these elements spatially can be spread out well by vibration processes, and this vibration processes conforms with and carries out along longer vibration section regularly.The length of channel architecture can such as in the scope of 20cm to 60cm, especially in the scope of 40cm to 50cm.Therefore, these elements should be able to again fill up without the need to opening machine cover plate in operational process, and are transported in pick-up area.
Whole device can be configured to removable unit, and it can be put back in warehouse, for follow-up application again filling up, under the part state that empties or empty completely.
" element " this concept can be regarded as all assembling elements in this document, and they can be positioned on component carrier.Element especially can be the SMT-element of the two poles of the earth or multipole or the element of other highly integrated plane, such as ball grid array, bare chip and upside-down mounting welding core.In addition, " element " this concept also can comprise mechanical part, such as, connect pin, plug, socket or similar object or photounit, such as light-emitting diode or photodiode.In addition, " element " this concept also can comprise the so-called RFID chip for so-called transceiver, and it is for so-called responser.
" component carrier " this concept can be regarded as various assembling object in this document, especially circuit card.Component carrier can be rigidity also or flexibility.In addition, component carrier both can have rigid region, also has flexure region.
By embodiments of the invention, channel architecture is provided with packaged unit.Packaged unit also can be arranged in channel architecture.This packaged unit can by rotating, passing or more the combination completely or partially closed channel structure of two kinds of motions.When rotatable supporting, by the simple rotation of packaged unit, the position that packaged unit can be opened from it or open position move to its position closed or make position and arbitrary midway location, and conversely.This midway location advantageously can be used for realizing the metered supply of element.
By another embodiment of the present invention, channel architecture has the first aperture on the first end of storing apparatus, and has the second aperture on the second end of drainage area.At this, this channel architecture can only be opened on first end and the second end.This point may mean, the passage that channel architecture has below, top and closes towards both sides.Therefore this channel architecture also can be described as tunnel.
Advantage channel architecture being configured to tunnel is, protects these elements along its conveying or vibration section, to avoid external action (especially polluting).In addition, these elements can not such as eject due to mechanical vibration undesirably.
This channel architecture can be made up of arbitrary material, and it only should be so firm in mechanical aspects, and the vibration namely produced by oscillatory system or shock motion are delivered on the bottom surface (electronic component is positioned on this bottom surface) of channel architecture, to transmit.
The material manufacturing channel architecture can be such as aluminium.Aluminium especially has following favourable characteristic: (A) it there is above-mentioned required impregnability.(B) although it is firm, relatively light.(C) it is easy to processing relatively.(D) it is nonmagnetic, is therefore not intended to magnetized element and can not be magnetically attached on inwall, the especially bottom surface of channel architecture.(E) relative low price of aluminium.
Should point out, channel architecture also can be made up of other suitable material certainly, and its characteristic that especially should have is, the element by vibrating transportation can not adhere on the material.
By another embodiment of the present invention, storing apparatus has filler device, and these elements are transferred to channel architecture from memory storage by this filler device.At this, the transfer of these elements especially can be realized in the simple landing of channel architecture by element.
By another embodiment of the present invention, this device also has identification component, and this device identifies relative to other device of same type by a well defined manner.This identification component that can such as be arranged in channel architecture can be configured to bar code, 2D code or RFID-chip.
This identification component can combine with the particular batch of the element of particular type or the element of particular type in a database.Therefore, the current filling situation of this device can be understood at any time under the help of data bank.Also possibly, the current occupied state on element is combined with identification component.In this case, operating personal can in time (namely before these elements exhaust completely) just notice, must change with the new memory storage with element the memory storage being arranged in storing apparatus.Equally, can determine when again applying described device by occupied state, whether be significant, and can again apply described device under which state if in automatic assembling machine or fitting line, again applying described device.
It is noted that when applying RFID-chip, need not forcibly application data base once.The data of these relevant elements and/or occupied state can directly be stored in the memory device of RFID-chip.
Expressing intuitively is, by the described application of identification component, can identify the element being arranged in this device like a cork.If the device described in this document multiple is for multiple element-feeding mechanism being subordinated to automatic assembling machine or being subordinated to the fitting line with multiple automatic assembling machine, if in known manner (such as by hand scanner) equip automatic assembling machine time can detect different identification components and correspondingly be considered, then can avoid in a straightforward manner two or more device be not intended to obscure.
By another embodiment of the present invention, this device also has mobilizable masking material, and it is arranged on the top of drainage area and can moves between the position of opening (open position) and the position (make position) closed.At this, the element be transported to drainage area can be picked up from top in this open position.This pickup is stoped by masking material in this make position.
By the masking material (it is also referred to as cover) of described activity, can prevent element or contaminate particulate from falling or infiltrating on drainage area or in drainage area in a simple and effective way.Equally, can prevent element from such as ejecting from drainage area due to the vibration of channel architecture.
The activity of mobilizable masking material and the operation of assembly head can synchronously be carried out, if therefore should be withdrawn from drainage area by one or more element by assembly head, then the masking material of this activity is only arranged in open position in a short period of time.
The masking material of this activity is used for moving to open position from make position or moving to make position from open position conversely, and preferably only performs the moving movement of simple machinery.This moving movement preferably only carries out along the longitudinal direction of described device or described channel architecture.Therefore, described device and element-feeding mechanism only have little locational requirement in its width, and described device is coupled on this element-feeding mechanism.So, this element-feeding mechanism can be coupled on known automatic assembling machine in an advantageous manner, replaces one or two conventional component tape supplying modes if desired.
By another embodiment of the present invention, this device also has the coupling device of machinery, can by mechanically coupled to each other for the motion of the motion of packaged unit and masking material by it.
The coupling device of this machinery can be simple mechanical device, and it such as has one or more gear, drives belt, joystick and/or other mechanical coupling element arbitrarily.
The advantage of the described mechanical couplings between packaged unit and the motion of masking material is, these two elements can be handled by common actuating device (such as by actuator).This actuating device especially can be subordinated to element-feeding mechanism, and described device is operationally coupled on this element-feeding mechanism.
Should point out, by vibration, the device that element is delivered to drainage area from memory storage should can be referred to electronic and mechanically passive device.This means, without the need to parts such as (a) actuator, (b) vibration exciter, (c) photographic camera initiatively, it is used for detecting these elements optically, and therefore they can reliably take off from assembly head; And/or (d) illumination equipment, be used for illuminating the element treating to be detected by photographic camera.If the parts of this active are necessary for fitting process, so that without the element (vibration exciter is all under any circumstance necessary) frictionally supplying separation, then the parts of these actives can be subordinated to element-feeding mechanism, and described device is operationally coupled on this element-feeding mechanism.
By another embodiment of the present invention, the masking material of this activity is optically completely transparent or local transparent, therefore illuminating ray can penetrate the masking material of this activity, and at least when the masking material of this activity is arranged in closed position or make position, this drainage area can be illuminated from top by illuminating ray.
By the masking material that this is optically transparent, can therefore illuminate from top by illuminating ray to the element in drainage area by vibrating transportation.If the photographic camera that the element be transported in this drainage area is arranged on below drainage area detects, then therefore this illuminating ray is background illumination, backlighting or illumination light transmission (so-called backlight).In order to relevant element can be detected by photographic camera from below, it is necessary that the element being arranged in drainage area is on the upper transparent supply part of educational inspector.Further preferably, this supply part can vibrate by one or more vibration exciter, and therefore these elements spatially can spread out by vibration in an appropriate manner in drainage area.
Should point out, supply part can be a part for described device or a part for alternatively element-feeding mechanism, and described device is operationally coupled on this element-feeding mechanism.
By suitable background-illumination, especially can reliably recognize, whether the element in this drainage area is positioned at is placed-direction vertically, this place vertically-direction in relevant element be not by primary side, and to lie on the upside of supply part by narrow side.In addition, described background-illumination also contributes to locus and/or the physical dimension of understanding fully the element be transported in drainage area especially exactly.
Another advantage of suitable background-illumination is, (a) masking material relative to activity and/or the pollution that may exist of supply part, and/or (b) is relative to the undesirably vibration (spectrum and/or in intensity) of background-illumination, element-detection is still very firm.
Illuminating ray or background-illumination can be such as the light sent by illumination equipment, and this illumination equipment is external illuminators relative to described feedway.
In this application documents, " optically transparent " refers to, at least in drainage area this supply part for can be printing opacity by the electromagnetic radiation that photographic camera detects.Therefore, optically the transparent supply part that refers to is printing opacity in the SPECTRAL REGION of photographic camera sensitivity.Therefore, optically transparent especially can refer to supply part for electromagnetic radiation in appreciiable, ultrared and/or ultraviolet SPECTRAL REGION at least local be printing opacity.But should point out, this is enumerated not is exhaustive, states in the literature " optically transparent " also for being different from the electromagnetic radiation in other region of described SPECTRAL REGION.
Expressing intuitively is provide background-illumination by described illuminating ray, wherein can measure these elements in its position and other physical dimension (such as laterally inclined, hive off, towards the spacing of adjacent elements).This background-throw light on relative to front lighting according to or the advantage of incident light-illumination it is possible to more clearly make component outline edge imaging, and therefore, it is possible to accurately measure its relative position.In addition, in the contaminated situation of supply part, or when such as making brightness epoch or fluctuation spatially due to light source aging of relevant illumination equipment, background-illumination still can realize metastable assessment.
When background-throw light on suitable, that can identify contaminate particulate and machinery especially well by optical measurement scrapes particulate.Therefore, it is possible to avoid, the pick tool (such as suction pipe) of assembly head is used to receive this particulate absent-mindedly.
By another embodiment of the present invention, the masking material of this activity comprises integrated illumination equipment, and therefore at least when the masking material of this activity is arranged in make position, the illuminating ray by this integrated illumination equipment can illuminate drainage area from top.
The illumination equipment be integrated in the masking material of this activity such as can have one or more light-emitting diode (LED).This integrated illumination equipment can also be the light source of plane expansion, and it such as can realize by organic light-emitting diode (OLED).
By another embodiment of the present invention, this mobilizable masking material has the material of optically scattering.This means, appear at the illuminating ray of element (it is arranged in drainage area) upside for the background-illuminating ray photographic camera being scattering by the masking material of this activity, it is especially homogeneous in its intensity.Therefore, carrying out detective cell by the photographic camera be positioned at below above-mentioned supply part, is especially favourable.
Should point out, this dispersion effect down, by improving with under type, is namely also provided with at the rear of the masking material (it is volume scattering device Volumenstreuer) of activity or top the layer optically reflected.
In addition be also pointed out that, the scheme that alternatively scheme or the layer optically reflected in the masking material of activity are combined is, also can there is the structure of refraction, its effect makes the light of coupling preferably towards post deflection, and incide on the element that appears at drainage area from top in as far as possible uniform mode.
By another angle of the present invention, describe a kind of element-feeding mechanism, be used to provide the element of separation.Described element-feeding mechanism is especially applicable to the electronic component being used to provide separation, and object is automatically assembled with component carrier in automatic assembling machine.Element-feeding mechanism has (a) frame, (b) is arranged on the device of oscillatory system in frame and (c) the above-mentioned type, be used for making element be transported to drainage area from memory storage by vibration, this memory storage comprises the element of bulk form, wherein the channel architecture of this device is mechanically coupled with oscillatory system, and therefore when operational shock device, these elements can be carried towards the direction of drainage area along longitudinal axis by vibration.
Described element-feeding mechanism is based on such cognition, namely by by the above-mentioned device being used for delivery element simply and be mechanically arranged in the frame of element-feeding mechanism, element is in a stowage arrangement before arrival supply area, and this stowage arrangement can be closed at off position place by mobile closing device.Therefore whole device can be removed from frame as the unit closed, and if the element being arranged in this device is not used further to next fittage, then this device temporarily can be deposited, until such element is again for other follow-up fittage with being positioned at together with the element inside it.
Described device can have one or more actuator, and they are mechanically coupled with channel architecture, and therefore oscillatory system vibrates when correspondingly controlling each actuator.This oscillatory system can have three or more actuator, and they are subordinated to vibrating shaft respectively and preferably can control independently of each other, and therefore channel architecture can along three different vibrating shaft directions vibrations.Targetedly vibration of element can be transported in drainage area by this way.These actuators also can control so if desired, and namely these elements can also transfer to the direction of memory storage again against its throughput direction originally.Such as, when delivered too much element absent-mindedly by vibration, then there is the danger that drainage area clamp-oned by too much element, cause the average headway between element too small, they no longer can reliably be picked up by the assembly head of automatic assembling machine, and so above-mentioned way has advantage.
By embodiments of the invention, element-feeding mechanism also has (a) supply part, and drainage area is positioned on its upside; And (b) photographic camera, it is arranged on the below of supply part, wherein supply part is at least optically transparent in the scope of drainage area, and the element be therefore transported in drainage area can penetrate supply part and be detected by camera optical from below.At this according to specific embodiment, this supply part can be subordinated to the device for delivery element, also can be subordinated to all the other positions of element-feeding mechanism.
Expressing intuitively is that described element-feeding mechanism has integrated photographic camera, and the element provided can penetrate optically transparent supply part from below by this photographic camera and detect.Element-feeding mechanism also can have the image-system being connected on back of camera, and therefore element-feeding mechanism is provided with complete image-system, and this image-system independently can carry out image evaluation to the element detected by photographic camera.In this image evaluation, can determine position and/or the orientation of the element provided in drainage area, therefore subsequently by suitably controlling the motion of assembly head, these elements can be received by each pick tool (such as suction pipe) of assembly head.
Should point out, supply part is also mechanically coupled with at least one vibration exciter of oscillatory system.By the suitable vibration of supply part, element can be made spatially to be dispersed in well in drainage area, therefore by having corresponding high reliability of technology during assembly head pickup device.
Described supply part, can be such as dull and stereotyped, it has smooth upside, and these elements can move on the suitable vibration of flat board is on the upside of this.This drainage area can be a part for the upside of supply part, and conveying is come and element that is that provide especially can be taken off from this drainage area by the assembly head of automatic assembling machine.
In the embodiment described herein, this photographic camera is arranged on the below of supply part.Expressing more accurately is that photographic camera is arranged on the below of the downside of supply part, and wherein the downside of this supply part is relative with the upside of supply part upside keeping flat element (if they are arranged in drainage area) and position that is that put.
Be integrated in by photographic camera in element-feeding mechanism, its advantage is, need not apply external camera to detect the element be transported in drainage area.Especially need not apply such photographic camera, namely it surveys the position of component carrier to be assembled in known manner in automatic assembling machine.The shortcoming applying this photographic camera natively existed in automatic assembling machine is, it such as must move on drainage area by gauntry crane vehicle frame in order to detective cell.At this, less desirable non-cutting time may be added in assembly technology, when therefore assembling many elements to component carrier, become slow, therefore efficiency step-down.
Should point out, the concept for for supply part " optically transparent ", the elaboration done for the optical clarity for mobilizable masking material is above suitable for too.
By another embodiment of the present invention, element-feeding mechanism also has illumination equipment, and it is arranged like this, makes it possible to illuminate the element being arranged in this drainage area.
This illumination equipment can have one or more light source, especially light-emitting diode.This light source can illuminate these elements with illuminating ray from different directions.
By another embodiment of the present invention, the element being arranged in this drainage area can illuminate from below.This point is such as by realizing with under type, and namely at least one light source is arranged on the below of supply part, and the element be therefore transported in drainage area can illuminate from below through transparent supply part.Therefore, these elements (in consideration when being arranged on the photographic camera below supply part) illuminate according to (front lighting) by so-called incident illumination or front lighting.By this illumination, photographic camera especially reliably can optically detect these elements.
By this this front lighting according to especially identifying by brightness value with high reliability, whether these elements appear on supply part with correct orientation.Such as the element this in two primary side one with connecting terminal, this element-orientation is important.Concept " primary side " refers to two sides with maximized surface of element.It is easily understood that these elements just must be assembled the pickup device receiving of head with correct orientation when being picked up by assembly head in fitting process, in this fitting process, element has been placed on component carrier down by its connecting terminal.
In addition by suitable front lighting photograph, the position by the element of vibration passing in drainage area can especially be determined exactly.This is equally applicable to the angle position determining the element be delivered in drainage area.Can see easily in this context, the position understanding the element picked up by assembly head is exactly important for failure-free pick process.Considering such fact, namely due to electronic component more and more micro-miniaturisation, and the size of the pick tool of the size of element and the suitable of assembly head (such as suction pipe) is more and more less, and this point is especially applicable.
Should point out, it is also important that for failure-free pick process, identify the position of adjacent elements, therefore, it is possible to guarantee, always receive an element exactly by pick tool respectively.If therefrom show that element to be picked up is arranged side by side overstocked mutually, then can start new vibration processes if desired, therefore these elements are dispersed in drainage area again.As already described, in this new vibration processes, these elements can also transport out against original throughput direction if desired again from drainage area.

Channel architecture 154 is vibrated like this by vibration exciter 112, and namely element is in figure 3 towards right conveying.Then, these elements are delivered to supply part 164 from channel architecture 154, and this supply part is equally configured to transparent oscillating plate as already described, and it has the drainage area for these elements.These elements can take off from drainage area by unshowned assembly head, to realize the object of automatic assembling element carrier.
Click here shown embodiment, this supply part or transparent oscillating plate 164 are mechanically coupled with three vibration exciters, wherein merely illustrate two vibration exciter 322a and 322b in figure 3.By these three vibration exciters, this transparent oscillating plate 164 can along three different direction in space vibrations, and therefore these elements can spatially be distributed in drainage area by rights.
In order to can reliably be taken off by the element being arranged in drainage area by assembly head, exact location and/or the orientation of the element provided must be known.The exact location of the element provided and/or orientation detect by image-system, as below by Fig. 4 in greater detail.This image-system has the photographic camera 130 of the below being arranged on supply part 164, and it penetrates transparent supply part 164 by mirror 132 and detects this element provided from below.The effect of illumination equipment 334 is, provides front lighting to shine to from below the element of supply.Can produce figure viewed from behind illumination by the masking material 160 of activity, the light source that the masking material 160 of wherein this transparent activity is used as plane carrys out use, and this masking material is made up of material that is transparent and/or astigmatism.For this reason, light is coupled in movable masking material 160 from below by illumination equipment unshowned in Fig. 3.This light in the internal reflection of the transparent and/or diffusion material of mobilizable masking material 160, and on the scattering position of optics astigmatism, therefore, it is possible to the element provided in drainage area is illuminated in top relatively uniformly.
Click here shown embodiment, element-feeding mechanism 100 also has electronic module 340.This electronic module 340 has control circuit and electronic drive circuit, to drive exiter 112,322a and 322b and unshowned driving device, is used between the make position shown in open position and Fig. 3, promote mobilizable masking material 160.Electronic module 340 also has treater 345, it be connected on photographic camera 130 below and carry out image evaluation, this image evaluation is necessary for the position of element and/or the determination of orientation.
It should be noted that this treater 345 also can be positioned at the outside of element-feeding mechanism 100, then the view data wherein detected by photographic camera 130 must be delivered on the treater of this outside by suitable interface.This ppu can such as realize by machine controller or in the machine controller of automatic assembling machine, and element-feeding mechanism 100 is coupled on this automatic assembling machine.
Fig. 4 depicts the optical case when carrying out optical detection to element 495, and these elements are positioned on vibratile supply part, and this supply part represents with reference marker 464 now.The masking material of the present activity represented with reference marker 460 is arranged in its make position, and therefore masking material 460 is positioned at the top of the drainage area defined by the space layout of element 495.For the reason of optical clarity, vibration exciter is not shown in the diagram, supply part 464 vibrates by this vibration exciter.
As set forth above, supply part 464 has been made up of optically transparent material.By this point, the place, space of the element 495 be positioned on supply part 464 or position and/or orientation can be detected optically.As shown in Figure 4, photographic camera 430 is arranged on the below of supply part 464.The light path of the light detected by photographic camera 430 is turned to by mirror 432, and this mirror is arranged on the below of supply part 464 equally.Supply part 464 is made up of optically transparent material, and therefore these elements 465 penetrate supply part 464 and detected by photographic camera 430 from below.
Mirror 432 is mirrors of optical translucent, and the illuminating ray 434a therefore sent by illumination equipment 434 can penetrate this semi-translucent mirror 432 and incide from below on supply part 464.Because supply part 464 is made up of optically transparent material, therefore these elements 495 can be illuminated by illuminating ray 434a from below.These elements are illuminated from the direction identical with the detection of photographic camera 430 by illumination equipment 434.Therefore, illuminating ray 434a is so-called front-illuminating ray.
In order to provide the so-called figure viewed from behind to throw light on to the element 495 detected from below by photographic camera 430, be also provided with the illumination equipment 436 sending background-illuminating ray 436a.Click here shown embodiment, background-illuminating ray 436a is coupled in movable masking material 460 from below.In the masking material 60 of this activity, by the reflection on the inwall of masking material 460 and by the scattering on the optical scattering center in masking material 460, the background of this coupling-illuminating ray 436a is scattered, therefore these elements 495 can illuminate from top by uniform background-illumination to a great extent.In order to improve the homogeneity of this background-illumination, masking material 460 clicks here shown embodiment and has optically different regions, the region 460b of namely optically transparent region 460a and optically scattering.The background sent by illumination equipment 436-illuminating ray 436a is coupled in this optically transparent region 460b.Such scattering in the region 460b of the light optically scattering in the region 460b of optically scattering is entered by optically transparent region 460a, namely background-illuminating ray that the downside of the region 460b of optically scattering sends has especially high homogeneity, as already described, it illuminates these elements 495 from below equably.
In order to improve the efficiency of background-illumination, the upside of the masking material 460 of activity can form unshowned reflecting horizon, therefore prevent a part of illuminating ray 436a to export on the upside of masking material 460 and therefore can not for the illumination of element 495 is as contribution.
Should point out, if the masking material of this activity 460 is arranged in make position, above-mentioned background-illumination 436a could be transmitted into element 495 from top.Before mobilizable masking material 460 moves to its open position, if background-illuminating ray 436a should be on the scene when carrying out optical detection, then must stop the optical detection being undertaken by photographic camera 430 pairs of elements 495.That is, only have drainage area freely can enter from top, therefore unshowned assembly head can take out the element 495 of first pre-test, to assemble unshowned component carrier.
Point out in addition, illumination equipment 434 and/or 436 realizes by a light-emitting diode or multiple light-emitting diode.At this, light sends out diode can launch the identical or different light of spectral region.
By this front lighting according to especially identifying by brightness value with high reliability, whether these elements 495 appear on supply part with correct orientation.Such as the element this in two primary side one with connecting terminal, this element-orientation is important.Concept " primary side " refers to two sides with maximized surface of element.It is easily understood that these elements 495 just must be assembled the stop motion mechanism receiving of head with correct orientation when being picked up by assembly head in fitting process, in this fitting process, element 495 has been placed on component carrier down by its connecting terminal.
By suitable background-illumination, the position by the element 495 of vibration passing in drainage area especially can be determined exactly.This is equally applicable to the angle position of the element 495 be delivered in drainage area.Can see easily in this context, the position understanding the element 495 picked up by assembly head is exactly important for failure-free pick process.Considering such fact, namely due to electronic component more and more micro-miniaturisation, and the size of the pick tool of the size of element and the suitable of assembly head (such as suction pipe) is more and more less, and this point is especially applicable.
Therefore expressing intuitively is that front-illuminating ray 434a and background-drainage area 436a is applicable to different lighting conditions, and under these lighting conditions, photographic camera 430 can recognize different angles or the characteristic of the element 495 detected.These two images detected under different lighting conditions or photograph preferably jointly are assessed by the assessment unit being connected on back of camera.At this certainly it is necessary that these two illumination equipments 434 and 436 can control separated from each other.
