Accurately in fact, the present invention relates to and treat to the logistical point of component carrier assembling electronic element. The invention particularly relates to a kind of assembly head, a kind of automatic assembling machine, a kind of assembly method and a kind of to the element-stop device of component carrier assembling electronic element.

Background technology

Concept " near-field communication " (English: NearFieldCommunication, NFC) be often referred to by radiotechnics in short distance (typically several centimetres) carry out contactless data transmission. Near-field communication is generally English by known RFID(in practice: radio-frequencyidentification, is identified in radio-frequency band by electromagnetic wave) technology realizes. RFID technique is the standardized technique of transmission-reception-system, is used for realizing contactless identification and location by radio wave.

RFID-system is made up of transponder and reading equipment, and this transponder is also referred to as label or wireless lebal in spoken language, and this transponder is used for reading the information such as mark or coding that are stored in transponder. But RFID-system also can include write device, passes the information on by it and stores on transponder. Write device and reading equipment can be combined in common construction unit.

RFID-transponder has electronic chip, and it is typically connected with antenna structure. This antenna structure can be such as made up of polymer by special printing method, in order to realizes stable circuit. Therefore, RFID-transponder and the like body can be made by cost very cheaply, therefore provides the application of broadness for RFID-technology. RFID-technology can and speculate can replace the bar code or the 2D-square matrix code that are nowadays also used extensively by future.

Recently, also had been developed that there is antenna integrated RFID-element. Alternatively, these RFID-elements also are able to couple with exterior antenna, therefore, it is possible to the NFC for having relevant RFID-element expands sensitivity and therefore expands effective range. In this document by RFID-chip and RFID-element hereinafter also referred to as RFID-part, this RFID-chip is necessarily connected on the antenna structure of outside, and this RFID-element has the antenna structure of inside.

Nowadays especially at logistics field applying RFID-part, in order to identify and trace (=follow the trail of) object. The data relevant with the object that these mark also are frequently stored on the RFID-part being fixedly linked with this object. These data can be aroused at any time again, and can update if desired or supplement. RFID-part is generally also used for protecting object, to prevent from forging and/or stealing.

If applied in the industry RFID-parts batch, such as it is used for manufacturing electronic building brick, then often these RFID-parts often to arrange user-defined mark or serial number before being placed on electronic building brick, or other data obtainable describe immediately after being also used in being placed on electronic building brick if desired. For this applicable cases it is necessary that as efficiently as possible (quickly and almost with other process simultaneously) and read and write single RFID-part targetedly.

For this commercial Application, RFID-Part Typical Part ground manufacturer be in namely before packing (such as on so-called element-belt roller) just describe with unique identifier. It is also known that had been written into the RFID-part wrapped in element-belt roller, then this element-belt must at least launch once and again to roll.

But the size according to RFID-part and opposed configuration, the danger that there is also when manufacturer's place's write and/or reading RFID-part is, multiple RFID-parts write at substantially the same time and/or read, and then cannot ensure that the position membership relation between each RFID-part and relevant write and/or the information of reading. So when describing RFID-part by the serial number advanced, it is impossible to guarantee that these serial numbers are applied with the order of complete raising and lowering or processed. In addition, apply even if also be able in element belt when ideally setting up the serial number of rising, RFID-part is for RFID-damage parts or processes bad reason and must abandon in follow-up assembly technology, therefore lacks a serial number in the order of this rising.

Summary of the invention

It is an object of the invention to, it is achieved the non-contact type data from RFID-part or towards RFID-part are transmitted, and this RFID-part should be placed on component carrier, in order to reliably and the distribution of simple manipulation ground can be pre-stored in information on RFID-part.

This purpose is achieved by the content of independent claims. Describe the advantageous embodiment of the present invention in the dependent claims.

By first angle of the present invention, describing a kind of assembly head, it is used for component carrier mounting electronic part. This assembly head has (a) and carries structure; The coupling element of (b) at least one machinery, it is arranged in carrying structure and so constitutes, and namely can lay part-stop device temporarily to receive electronic component; And (c) communicator, it is arranged in carrying structure and so arranges, and namely contactlessly exchanges data with the electronic component received by part-stop device when employing wireless communicates.

The theoretical basis of described assembly head is in that, exchanging (exchange of these data is to carry out before the part participating in data exchange is about to location) by data and guarantee faultless membership relation between related data and electronic building brick with particularly simple and reliable way, relevant part is subordinated to this electronic building brick by assembly technology when applying assembly head or adds in this electronic building brick. This especially reliable membership relation is based on following facts, namely the data exchange between correlated parts and communicator realizes for assembly technology on such time point, namely at this moment between put and successfully finish relatively crucial operation, for instance Part supplying to part-extraction position and is received this part by element-stop device.

In other words, guarantee with the probability close to safety at a time point, successfully to the part that component carrier assembling is relevant. After visual detection to the part received by part-stop device and carry out data exchange, drawing from this visual detection, this relevant part does not damage at least from the teeth outwards and/or is correctly received by part-stop device. In other words, the exchange of these data can be confined on such part, and namely this part is adapted for carrying out successful assembly technology and thus without abandoning.

This communicator can be designed to for realizing exchanging with the two-way of correlated parts or only unidirectional data, and this part can carry out radio communication. When carrying out bidirectional data exchange, communicator is read-write equipment. When carrying out bidirectional data exchange it is essential that whether these data are delivered to communicator from part, still it is delivered to part from communicator in turn. When carrying out unidirectional data exchange on the communication device, this communicator is reading device. When carrying out unidirectional data exchange on part, this communicator is to write to put device.

Concept " carrying structure " is in this document it will be appreciated that be various concrete space structures, and the different parts of assembly head can may move or be arranged on still on these space structures. In addition this carrying structure can so be constituted, namely they can directly or with gap arrange on the positioning device, assembly head can by this positioner in the inside of automatic assembling machine along at least one but move preferably also along two directions preferably mutually extended. Extended preferably in the plane horizontal or vertical relative to gravity by this positioner direction of motion set in advance.

The coupling element of this machinery can be arranged in carrying structure still. In this case, assembly head must move relative to component carrier to be assembled when laying part. But, the coupling element of this machinery may move relative to carrying structure in known manner, and can move along z-direction by linear drive apparatus, wherein this z-direction is preferably perpendicular to this direction or such direction orientation, and namely whole assembly head can move along the direction by above-mentioned positioner.

The coupling element of machinery is preferably so constituted, and the part-stop device being namely configured to suction pipe can be arranged on above it, and this part-stop device can remain part by low pressure in known manner. The coupling element of this machinery should so be constituted in this case, and namely low pressure can be delivered to the suction channel of suction pipe from the low pressure of assembly head-generation unit, and therefore relevant part is maintained on the side of suction pipe in known manner.

Also have the advantage that by the assembly head of the present invention, the moment that this correlated parts carrying out data exchange carries out data exchange at other part is spatially separated by so remote, make also reliably to carry out data exchange to part relevant, that kept by part-stop device, and by mistake will not carry out data exchange with other part, other part described refers to and is assembled to before or after this correlated parts and is therefore typically subordinated to the part of other electronic building brick. That is, reliably carry out data exchange with desired part 194, but data exchange will not be carried out with other part.

In this context it may be noted that in the category of assembly technology after receiving part from part-extraction position, these Part Typical Part ground are spaced must be substantially more farther than the time point before extracting part. Before extracting, these parts or (a) are positioned on part belt, now part forms a line on this belt and closely arranges successively, (b) being arranged in the display area (when part is processed into bulk materials) of corresponding bulk materials-carrier, now part is being assembled before head extracts and is arranging same close apposition in this carrier.

In assembling technology procedure, in certain interval, data exchange is carried out preferably between electronic component and the communicator being arranged in carrying structure, in this interval, assembly head moves to assembly area from receiving area (accommodate these parts this receiving area), is placed on component carrier to be assembled at this assembly area electronic component. Therefore, it is possible to carry out exchanging by the data of the present invention in the flow process of conventional linkage editor, therefore do not have extra nonproductive non-cutting time when automatically assembling element carrier.

These data are transmitted in one or both directions by described data exchange, these data can be such as mark or serial number, and they are in type or have marked this part individually, be subordinated to the electronic building brick of this part and/or the component carrier of assembling. If should in logistics the production technology of tracking electronic assembly, then the latter is even more important. But the data of these exchanges also are able to comprise such information, namely describe the feature of the assembly being subordinated to this part by these information, be positioned at the electronic component near this part or this part itself. So this information such as application when maintenance, in order to replaced the part of damage by similar part. Such as in the light emitting diode, these information can illustrate the color of light, and this light is sent by light emitting diode, and can not or be difficult to when light emitting diode damages find from the outside.

By embodiments of the invention, communicator may move relative to carrying structure. Therefore, it is possible in an advantageous manner, communicator is enable to sail near correlated parts. This can realize again the exchange of reliable and quick data.

If electronic component is the RFID-element with internal antenna structure in addition, then the spacing little as far as possible between communicator and relevant electronic component is especially advantageous. Because this part is architectural limitation typically only has very little antenna structure, so also correspondingly little relative to electromagnetic sensitivity. Therefore when (a) writes justice data on RFID-element, data exchange needs the electromagnetic radiation incided on RFID-element that intensity is very high, and (b) needs high sensitive communicator when reading the data of RFID-element. Clicking here the embodiment of description, the two condition can meet in a straightforward manner in the following manner, and namely when data exchange, spacing between RFID-element and communicator is very little and typically up to 5mm.

The relevant less spatial separation between part and communicator has the additional advantage that, the write of data and/reading can be passed through communicator and implement in very short interval, and/or the required transmission power of relevant electromagnetic radiation can be very little, without the exchange of defective data is produced especially high danger.

By another embodiment of the present invention, communicator can move relative to carrying structure only along presetting motion path. Its advantage is, simple machinery is just enough to regulate the smaller spacing between communicator and associated electrical part.

Communicator preferably moves along direction set in advance along motion path set in advance in space, and the direction is defined by straight line and motion path set in advance is defined as linear axis. But alternatively this direction of motion also can refer to the rotary motion round rotation axis set in advance, this rotation axis is spatially static relative to carrying structure. The simple driver of only one is just enough to make communicator move towards relevant electronic component in both cases.

By another embodiment of the present invention, radio communication has near-field communication. Enabled in particular to refer to the wireless or contactless communication on the basis of known RFID-technology by the near-field communication applied by the assembly head of the present invention. In this case, part-stop device the part received is RFID-chip and especially RFID-element, and it has integrated antenna structure. In addition in this case, communicator is RFID-communicator.

By another embodiment of the present invention, assembly head also has the coupling element of at least another machinery, and it is arranged in carrying structure and so constitutes, and namely can lay another part-stop device temporarily to receive another electronic component.

Expressing intuitively is that communicator is arranged in the carrying structure of the described assembly head being made up of several parts. This assembly head being made up of several parts can receive multiple part in known manner first continuously from part-receiving area, then these parts transmit the part-assembly area to automatic assembling machine together, and these parts are placed on component carrier to be assembled successively in part-installation site that it is relevant.

If only only one RFID-part is received by the assembly head being made up of several parts, is carried and assembling (being generally all this situation) within assembly period, then by intelligentized part-receiving, the RFID-part being correlated with can be made only to be received by such part-stop device, and namely its tip is positioned at the inside of the spatial interaction effect of communicator. This intelligentized part-receiving, it is possible to realize in a straightforward manner with conventional program (logistics in automatic assembling machine). A flow process of the following steps of concept " assembly period " (being made up of several parts) assembly head in this context: receive at least one part from part-receiving area or in part-receiving area; (2) this at least one part is delivered in the part-assembly area of relevant automatic assembling machine; (3) this at least one part is placed on component carrier to be assembled; And (being made up of several parts) assembly head sailed and returns in part-receiving area by (4).

(being made up of several parts) assembly head described by this embodiment can be such as matrix head, and plurality of part-stop device is arranged and directed in parallel to each other at one-dimensional or two-dimentional array. Each part-stop device preferably can vertically move by linear drive apparatus individually, in order to receives part respectively or is placed on component carrier to be assembled by part respectively.

By another embodiment of the present invention, assembly head also has at least another communicator, it is arranged in carrying structure and so arranges, and namely contactlessly swaps data with by another electronic component received by other part-stop device when employing wireless communication. The advantage of this point is, in assembly period especially when the assembly head being made up of several parts shifts to part-assembly area from part-receiving area, can not only exchange data with a part, and can also exchange data with two parts. Therefore, it is possible to improve the quantity of RFID-part, these RFID-parts can with the communication of described assembly head.

By another embodiment of the present invention, assembly head also has rotation axis static in space relative to carrying structure. Additionally, the coupling element of the coupling element of this at least one machinery and this at least one other machinery can rotate round rotation axis.

These coupling elements are preferably provided on rotor structure, and this rotor structure can rotate round rotation axis

Express intuitively and be, (being made up of several parts) assembly head described in this embodiment can refer to so-called hexagonal assembly head, and wherein mechanical coupling element and accordingly part-stop device are also therefore widely differently outstanding from footpath rotation axis and jointly rotate round rotation axis. This communicator can so be arranged on load-carrying unit at this so that the electronic component received by part-stop device when part-stop device rotates moves continually by the electrical interaction region of communicator.

This rotary motion carries out with especially having beat, therefore just makes each part-stop device carry out complete rotation round rotation axis by the certain amount of spin step quantity of part-stop device (its quantity be equivalent to). The rotary motion of beat can be accurately realized in known manner at this, namely part-stop device is all placed exactly in the position (also referred to as 6 positions) of bottom after each spin step, can receive part by correlated parts-stop device or is placed on component carrier to be assembled by the part of receiving in this position.

Another of the described data exchange carried out in conjunction with hexagonal assembly head is also advantageous in that, different parts-stop devices the spacing between the part adjoined each other received is relatively large. Therefore, it is possible to jeopardously individually identify these electronic components without obscuring, and can be reliably written and/or read.

By another embodiment of the present invention, assembly head also has photographing unit, and it is arranged in carrying structure and so arranges, namely from one image of electronic component photographs received by other part-stop device.

The image of this shooting can be estimated when applying algorithm known by the data processing unit being connected on back of camera, in order to carries out image procossing. Therefore, it is possible to determine in known manner, whether whether relevant part be subject to mechanical failure and correctly received by the part-stop device being correlated with, and therefore it is capable of the correct assembling of component carrier to be assembled.

Expressing intuitively is that described photographing unit is so-called imaging station, and component carrier to be assembled carried out optical detection by beat continuously and preferably in this imaging station before being placed on component carrier. Only this detection has been guided out the result in front, is just placed in truly on component carrier by relevant part.

Described communicator can regard another treating stations as relative to imaging station, carries out data exchange in this treating stations between communicator and each electronic component. This other treating stations is below also referred to as communication station. These parts received by single part-stop device preferably penetrate this communication station in the way of identical with imaging station and process with having beat. If communication station is relative to being positioned on correct position by the rotary motion of beat (being namely about to the position before 6 positions of arrival), then part is placed on component carrier to be assembled by translation on this position, then ensures that and only processes the part being considered as being suitable for assembling in advance by optical detection in a communication station. Then only carrying out data exchange with such part in an advantageous manner, namely these parts with close safe probability and are placed on component carrier to be assembled truly. If in a communication station to extract Tong Bu with the optical detection in (a) imaging station and (b) part or to carry out data exchange with identical beat, then compared with known assembly head, the described data exchange on this assembly head intactly can carry out within cycle time.

Should enabling in particular to so carry out by the motion of beat, namely electronic component is positioned at relevant treating stations (=imaging station or communication station) respectively at short notice in relative to the carrying nonmotile situation of structure. Therefore, it is possible to not only guarantee high-quality image taking in a straightforward manner, but also can ensure that the faultless data exchange between communicator and correlated parts.

It is noted that had this imaging station in many known hexagonal assembly heads, the part received in imaging station stops with specific beat when routine operates and carries out optical detection. It is therefore not necessary to too many cost just can lay suitable communication station in this known hexagonal assembly head. This communication station is so arranged preferably with respect to imaging station, if namely the first part is arranged in imaging station in shorter interval, then the second part is just arranged in treating stations in identical short interval.

By implementing optical detection and data exchange on hexagonal assembly head, as set forth, as long as having completed optical detection for relevant part before data exchange and being considered as relevant part being suitable for assembly technology at this, just largely avoid abandoning or losing of correlated parts in the moment of data exchange.

By another embodiment of the present invention, photographing unit and communicator are positioned such that or are arranged in carrying structure, namely the first electronic component received can be grasped by camera capture simultaneously, and can implement data exchange between communicator and the second electronic component received.

Its advantage is, described communicator can be arranged on the hexagonal assembly head of known type in a relatively simple manner. For frame for movement (communicator is arranged in carrying structure by it), designer's (it possesses the assembly head structure described by this embodiment) has very big degree of freedom. Therefore, assembly head can realize in the way of particularly simple.

By another embodiment of the present invention, photographing unit and communicator are positioned such that or are arranged in carrying structure, namely the first electronic component received can be grasped by camera capture simultaneously, and can implement data exchange between communicator and the electronic component with individual receiving. The basis of the embodiment of the assembly head described in this document is in that, the optics undertaken by electromagnetic wave in spectral region catches and do not have the reciprocal action of interference between the data exchange that undertaken by electromagnetic wave (typically for the spectral region of RFID transponder) in another spectral region. Namely can create the treating stations of combination, and the quality of optics seizure and/or data exchange is not affected, this treating stations both carry out optics seizure and has been also carried out data exchange. The advantage of this point in particular, in that, by laying described communicator, or only can will not expand the physical dimension of assembly head slightly. Therefore, this assembly head can be applied in the automatic assembling machine of routine in simple and advantageous manner, without installing bigger assembly head in this automatic assembling machine additional.

By another embodiment of the present invention, assembly head also has signal transmitting element, and it can be arranged on the coupling element of at least one machinery, and is connected conductively with communicator. This signal transmitting element is so constituted, and namely it can couple with antenna structure, and this antenna structure is arranged in part-stop device or on part-stop device.

Radio frequency signals to be sent can be sent to described antenna structure from communicator by this signal transmitting element, and/or the radio frequency signals received is delivered to communicator from antenna structure. By described antenna structure, part-stop device the electronic component received can couple with communicator in electromagnetism by minimum spacing. Therefore, it is possible to realize the electromagnetic signal transmission described by data exchange with extremely little power, therefore can also carrying out reliable data exchange with above-mentioned RFID-element in its simplest form, this RFID-element has the antenna structure of inside in chip housing.

Especially the big advantage of this embodiment many applicable cases is in that, data exchange can realize the space membership relation being especially accurate to relevant electronic component, and the antenna structure of communicator has spacing little as far as possible towards the electronic component received on part-stop device in this embodiment. At this it may be readily seen that especially can draw this advantage from only small power, this power is necessary for fine pitch that data exchange.

Described signal transmitting element is simple connecting terminal in the simplest situations, and it can set up electrical contact between antenna structure and communicator.

By first angle of the present invention, describing a kind of automatic assembling machine, it is used for component carrier automatically mounting electronic part. The automatic assembling machine described has (a) framework (b) alignment system, and it has stationary parts and movable part, and wherein this stationary parts is arranged on framework; And the assembly head of (c) the above-mentioned type, wherein carrying structure is arranged on the movable part of alignment system.

Described automatic assembling machine is based on following knowledge: above-mentioned assembly head is used on the one hand implementing the common assembling of component carrier in an advantageous manner, is used for realizing data between (a) (near field-) communicator and (b) are for the electronic component of wireless communication designs on the other hand and exchanges. As having been described above, carry out at substantially the same time by the two task of the assembly head of the present invention, therefore do not need the extra time by the exchange of described data. Data between communicator and associated electrical part exchange therefore, it is possible to simultaneously carry out with other process. It means that efficiency of assembling will not be reduced, namely the number of parts on component carrier can be placed in each unit of time.

In order to electronic component is placed on component carrier to be assembled by the optional position enabled on component carrier, alignment system is preferably so-called surface-alignment system, assembly head can move freely through by this alignment system in region, location set in advance in xy-plane, and this xy-plane is parallel to the surface of component carrier to be assembled. If however, it will also be understood that guarantee simultaneously, the component carrier of stand-by multiple electronic components assembling can be perpendicular to the direction of motion of straight line-alignment system during assembling and move, then can also apply simple straight line-alignment system to replace surface-alignment system.

By another angle of the present invention, describing a kind of method, it is used for the assembly head of the automatic assembling machine above-mentioned by the above-mentioned type or the above-mentioned type to component carrier automatically mounting electronic part. Describe method have: (a) by be arranged on machinery coupling element on part-stop device to receive electronic component; When employing wireless communicates, between the communicator and the electronic component of receiving that are arranged in carrying structure, carry out the exchange of data.

Described assembly method is based on following knowledge: carry out data exchange by above-mentioned assembly head between (i) communicator and the electronic component (ii) only received by part-stop device in the way of simple and reliable. Guarantee by this way to read in and/or write out process for the clear and definite membership relation on the electronic component of wireless communication designs.

By embodiments of the invention, carrying out data exchange within such time period, namely assembly head shifts to the assembly area of automatic assembling machine from part-receiving area within the time period.

As having been described above, receiving area refers to such area of space in this context, namely receives electronic component in this area of space or from this area of space and typically arranges part-feeding mechanism, in order to supplying electronic component continuously. In addition assembly area also refers to such area of space, and namely electronic component is placed on component carrier to be assembled in this area of space.

From by the assembly head of the present invention from receiving area move towards assembly area time, as set forth, described data exchange has very big advantage, compared with known assembly head, it is possible to intactly carry out described data exchange on this assembly head with other process simultaneously. Therefore, the efficiency of assembling of corresponding automatic assembling machine will not be reduced.

By another angle of the present invention, describe the part-stop device of a kind of temporary transient receiving electronic component. Described part-stop device has (a) coupled sections, it mechanically can be coupled together with the coupling element of the machinery of the assembly head of the above-mentioned type, (b) basal body structure, it is connected on coupled sections, (c) antenna structure, it is arranged in basal body structure or goes up and have connecting terminal, and antenna structure can be connected with communicator by this connecting terminal.

Described part-stop device is based on following knowledge: can be used between the electronic component of radio communication to realize especially little spacing at the parts (i.e. antenna structure) and design that participate in the exchange of described data by part-stop device and antenna structure (it is subordinated to above-mentioned communicator) being combined. This especially creates above-mentioned advantage, namely just can ensure that by electromagnetic power very that reliable data exchange. Creating reliable space membership relation between this external communicator and electronic component, this electronic component is coupled with the antenna structure of electromagnetic mode Yu communicator during data exchange.

It should be noted that, also can realize data exchange if desired between communicator and electronic component by part-stop device described herein, this electronic component is that design for radio communication and is embedded in component carrier already by the processing step terminated or has been placed in component carrier.

By embodiments of the invention, part-stop device also has suction channel, it extends between the coupled sections and tip section of part-stop device and so constitutes, and namely loads, by the low pressure produced by the low pressure of assembly head-generation unit, the electronic component being positioned in the section of tip.

Therefore element-the stop device described by this embodiment is suction pipe, and it is known for its maintenance function and is generally used for assembly technology. But, suction pipe described herein has antenna structure extraly, and it can be arranged in suction pipe or on suction pipe.

By another embodiment of the present invention, coupling device has two electric connection contacts.

These electric connection contacts enable in particular to for setting up electric current connection between communicator and antenna structure. Therefore, it is possible to communicator and antenna structure are coupled together by particularly simple mode.

It is noted that this electric current connects also is able to have three, four even more than connecting terminal, antenna structure can be coupled together by these connecting terminals and communicator. Therefore, it is possible to create the RFID-circuit of activation between antenna structure and communicator, especially RFID-antenna booster.

By another embodiment of the present invention, this coupling device has another antenna structure, and it can couple with communicator with electromagnetic mode.

Expressing intuitively is that, in order to the data realized from communicator to electronic component exchange, this other antenna structure is reception antenna, and it can wirelessly receive data from communicator (it also has antenna in this case). Then these data received are delivered to antenna structure with current system, and then this antenna structure contactlessly passes data to electronic component. When carrying out data exchange from electronic component to communicator, this other antenna structure is transmission antenna, and it is connected from antenna structure reception data by electric current, and these data are contactlessly transferred to communicator by right thing.

The advantage of this other antenna structure is when laying part-stop device, and electric connection contacts need not contact with each other. This other antenna structure hence helps to improve the reliability of data exchange.
