Feeding device for electrical components and method for conveying components in a feeder

The following invention relates to a feeding device for electrical components for a placement and a method for conveying components in a Zuführ¬ device.

In placement machines for equipping substrates with electrical components, supply devices for electrical components are arranged on the side of a transport path for the substrates. A movable by a positioning sawn piece of placement head picks up the electrical Bauele ^¬ elements on the feeding means, moves them to a placement area of placement, in which the material to bestücken¬ de substrate is provided, and sets the electrical component on the substrate.

In a European by the disclosure of EP 0859 543 is known a feeding device to a coil wound auf¬ component belt, having gene which pocket-like Vertiefun ^¬, in which the components are successively net angeord- transported by a transport to a pick-up position of the feeder. Before the spool unwinds from the spool, the strap end is mechanically connected to the beginning of a component spool wound on a new spool by means of a splice. Subsequently, the unwound coil is removed from the Zuführein ^¬ direction and replaced by the new coil. Furthermore, it is known from the prior art to inform the Bedien¬ staff, if the early expiry of the construction ^¬ elementegurt signs in order to be able to initiate appropriate measures for the exchange of Bauelementegurts. Between the information of the operator by the feeder and the leakage of the component belt, the operator must After detecting the material requirement message by the feeder, the operator must move to the corresponding placement machine in a more or less large production hall, identify the type of component belt required, remove it from a warehouse, scan the new construction belt on the placement machine and match it with the need to remove and unwind the finished component belt from the corresponding feeder, splice the new belt to the old belt and the new one

Insert component strap in the feeder. In modern production plants, a large number of different feeders are attached to the placement machines whose component straps run empty at different times as required. If it is not possible for the operator to carry out all the above-mentioned activities properly in the short time window, the respective component belt that is ending is running out and the production line must be stopped until a new belt is inserted. Such a stoppage of a placement machine or a whole

Production line attracts high costs and the long time ^¬ pressure brought to bear on the servers, increases the error rate.

It is therefore the object of the present invention to provide a feed device for electrical components and a method for conveying electrical components in a feed device, thereby increasing the reliability of the Be ^¬ piece of equipment.

This object is achieved by the feeding device according to the independent claim 1 or 4 as well as by the method according to the independent claim 9 or 11.

A feeding device according to the invention of claim 1 includes fully alongside a main conveying mechanism, which mentegurt a Bauele ^¬ för¬ changed to a pick-up position of the feeder, two auxiliary support mechanisms Hauptfördermecha- the nismus each be able to supply a Bauelementegurt. If the end of the respective geför by the main conveying mechanism ^¬ derten component tape by a common Erfassungsein ^¬ direction detected, one of the auxiliary conveying mechanisms to the main conveying mechanism a new component tape, subsequent to the end of the expiring component tape to. As a result, the time window for refilling a belt is increased considerably, so that the operator gets sufficient time for refilling a new belt. Furthermore, the splicing of the end of the expiring belt with the beginning of the new belt is no longer necessary, which greatly simplifies the Gurtwechselvorgang. In summary, the operational reliability of a placement rate by a ^¬ a feeding device according to the invention can be significantly increases overall.

The supply means may in accordance with claim 2 are designed to the effect aus¬ that two further individual detection are provided ^¬ facilities, of which the end of the conveyed from the first conveyance auxiliary mechanism Bauelemen¬ tegurts and the other end of the conveyed from the second conveyance auxiliary mechanism component tape detected. Since the first and the second individual detection device are provided in the conveying direction before the common detection device, it is possible to detect the end of one of the Bauele ^¬ mentegurte even earlier. As a result, the time window for changing the component strap for the operator is increased even further.

In a further embodiment of the feeder according to

Claim 3, the common detection device is arranged at a predetermined distance to the pickup position of the Zuführeinrich¬ device. Is detected from a Hauptfördermechanis ^¬ mus component tape conveyed by the common Erfas- sungseinrichtung one end, a control device of the feeder with knowledge of the distance from the Er¬ can capture means to pick-up position and a uniform Distance of the components on the component belt calculate the exact number of elementegurtes between the pick-up position and the end of Bau¬ remaining components. This makes it possible to associate each component with a high degree of accuracy to a specific component belt, which allows complete verification of the components used, as is frequently required by customers. Fig on a cost-intensive and frequently ^¬ less accurate splice detection, as it is performed when connecting two belt ends by means of a splice can thereby be avoided.

A feed device according to the invention according to independent claim 4 differs from the feed device according to claim 1 in that it dispenses with a common detection device and only two individual detection devices are provided, one of which is the end of the first auxiliary conveying mechanism associated Bau ^¬ elementegurtes detected and the other the end of the two ^¬ th auxiliary conveyor mechanism associated component belt detected. For the advantages of the feed device is made to the explanations be ^¬ züglich according to Claim. 1

According to one embodiment of the invention Zuführein¬ device according to claim 5, the feeding means may comprise a check-pointing device that indicates to the operator when ei¬ ne detection means the end of a component tape ^¬ he holds. As a result, the operator is informed that one of the component straps soon expires and has to be replaced.

To the reloading of a faulty component tape in egg ^¬ nen to prevent the auxiliary support mechanisms, can on the Zu¬ transfer device according to claim 6, a determination device can be provided, determines the characteristic data of the components of a nachzulegenden third component tape and the tracking only possible when the nachzuführenden Components with the required for the placement process Components match. As a result, tracking the wrong components can be prevented from the outset.

Usually, the components are mounted in respective recesses of the component tape and covered with a cover film abge ^¬, to prevent falling out of the components. In general, a puller for the cover is provided in such a case on the feeder before the pickup position. To ensure that even the cover of a new component strap automatically by such

Puller is removed, an embodiment of the feeder according to claim 7, a connecting device which connects the cover of the leaked component strap with the cover of a new supplied component strap. Thereby, a smooth operation of the device Zuführ¬ is ensured without the operator having the Abdeck¬ sheet of a newly-fed components belt with one of the ^¬ like puller must bring first in engagement.

Such a connection device can be designed according to claim 8 so that it connects the cover sheets by means of an adhesive strip. Bonding prevents either the component strap or the components themselves from being damaged.

An inventive method for conveying components in a feeder according to claim 9 relates to a feeder, with the auf¬ under claim 1 auf¬ led features, wherein first the end of the respective funded by the main conveyor mechanism first or second component belt is detected and subsequently the first component tape after the end of the two ^¬ th component tape to the main conveying mechanism is supplied, if the end of the second component tape is detected, or the second component tape is fed to the main conveying mechanism following the en ^¬ de of the first component tape, if the end of the first component tape is detected. Apply to this procedure analogous to the bezüg ^¬ Lich of claim 1 mentioned advantages.

The embodiment of the method according to claim 10 includes the calculation of the number of components that are elemental belt between the pick-up position and the end of the first and second Bau¬. With regard to the advantages of this Aus¬ design reference is made to claim 3.

An inventive method according to claim 11 relates to a supply device with the features of Anspru¬ ches 4, and comprises the process steps analogous to the procedural ^¬ ren claim 9.

In the embodiment of the method according to claim 12 it is ensured that the feeding of a new component gate takes place taking into account the grid with which the components are provided on the component straps. This means that the respective new component tape, subsequent to the end of each outgoing Bauelementegur¬ TES so the main conveying mechanism is supplied, that the distance between the last device on the auslau ^¬ fenden belt and the first component on the new belt is equal to the Distance of the components on the expiring belt corresponds. This ensures that the distance in which the components are conveyed to the pick-up position remains uniform even during a component change. Splicing of the end of the outgoing belt and the beginning of the new belt is therefore not necessary and the operation of the placement can be smoothly fortge ^¬ sets.

The embodiments of the methods according to claims 13, 14, 15 and 16 result analogously from the embodiments of the feed devices according to claims 5, 6, 7 and 8, for which reference is also made to these claims with regard to the advantages. In the following, the feed devices according to the invention and the methods according to the invention will be explained in more detail with reference to two exemplary embodiments with reference to the attached figures, in which:

Figure 1 is a schematic representation of a first Ausfüh¬ insurance example of the feed device according to the invention, and

Figure 2 illustrates a second embodiment of the feeding device according to the invention.

1 shows schematically a first embodiment of the feeder according to the invention 1. The feeding device 1 comprises a main conveying mechanism Sl, which has a construction ^¬ elementegurt 2 in a conveying direction (in Fig. 1 and indicated by an arrow 2) to a pickup position 3 of Zuführ¬ device 1 promoted. The components used therein ^¬ belts 2 have pocket-like recesses into which the components in a defined and uniform distance b are arranged one behind the other. The main conveyor mechanism Sl can be realized for example by a transport wheel, which has on its outer circumference radially projecting pins on ^¬ , which engage in corresponding perforations of the Bauelementegur- tes. The main conveyor mechanism Sl transports the components present in the component tape to the pickup 2 gradually position 3 where a (not Darge ^¬ imputed) (not shown) Bestückau ^¬ tomatoes and this accommodates placement of a transported away. Immediately after the recording of the device, the main conveyor mechanism Sl is further clocked, so that the next component is transported to the collection position 3 from ^¬ . The increment of the main ^¬ conveying mechanism Sl is adjusted so that the construction ^¬ elementegurt 2 is further conveyed at each feeding step by the distance of the devices on the belt, that is, transports the subsequent component to the pickup position 3 after pick-up of a component becomes. The feeder 1 further comprises a first auxiliary conveying mechanism S2 and a second auxiliary conveying mechanism S3, which may have a similar structure to the main conveying mechanism S1. The first and the second auxiliary conveying mechanisms S2 and S3 are designed such that they feed a first or a second component belt 2 in succession to the main conveyor mechanism S1.

In the conveying direction before the pick-up position 3, a common detection device OS1 of the feed device 1 is arranged such that it detects the end of a first or second component belt 2 currently being transported by the main conveyor mechanism S1. In the exemplary embodiment shown in FIG. 1, the common detection device OS1 is located in the conveying direction in front of the main conveyor mechanism S1. As is apparent from Figure 1, the feed device 1 a first individual detector OS2 and a second individual detector OS3 may optionally have, WEL surface in the area of the first and second Hilfsfördermecha ^¬ mechanism S3 are arranged, and thus in the conveying direction at a distance from the common detection direction. The first individual detection device OS2 is arranged so that it detects the end of the first component belt 2, if it is conveyed by the main conveyor mechanism Sl. OS3 Similarly, detects the second individual detecting means, the end of the second Bauelemente¬ belt 2 when this ge from the main conveying mechanism Sl ^¬ is promoting. The joint detecting means OSI and the first and second individual detector OS3, for example, as optical sensors having a Mar ^¬ kierung recognize the end of each component tape 2 o-, be formed as the through-beam sensors.

The feeder 1 also has a Anzeigeein¬ direction AE, which signals an operator of the feeder 1 by an optical signal that the end of the first or second component belt 2 was detected by either the common detection device OS1 or optionally by the first and second individual detection device OS2 and OS3.

Furthermore, the feed device 1 has a Steuerein¬ direction SE, which controls all operations of the feeder 1 and coordinates. The control device SE is electrically connected to the main conveyor mechanism S1, the first and second auxiliary conveyor mechanisms S2 and S3, the common detection device OS1, the first and second individual detection devices OS2 and OS3.

The first and second auxiliary conveyor mechanism S2 and S3 can, if required, for example, by the operator, a further third component tape 2 via a feed chute 4 leads are fed ^¬. The feed chutes 4 of the first and second auxiliary conveyor mechanisms S2 and S3 are each closed by an electrically actuated closure element 5. Both closure elements 5 are electrically connected to the Steuereinrich ^¬ device SE and are actuated by this. Means connected to the control unit SE of the feeding device 1 determining means 6, for example, a handheld scanner, ER summarizes the kinds of components in a component belt 2 which is to be the first or second auxiliary conveyor mechanism guided S2 or S3 to ^¬.

In order to prevent falling out of components 2 from the pocket-like depressions of the component straps 2, the recesses are usually covered with a cover film 7.

This covering film 7 is removed shortly before the picking position 3 by a pulling device (not shown) of the feeding device 1, so that the placement head of the placement machine can pick up the exposed components.

The embodiment of a feed device OF INVENTION ^¬ to the invention 1 shown in Figure 1, a Verbindungsein- Direction 8, with which the cover 7 of a subsidized by the main conveyor mechanism Sl component belt with the cover 7 of a tracked by the first or second auxiliary conveyor mechanism S2 or S3 component strap 2 can be connected. In the exemplary embodiment, the connecting device 8 consists of a first coil 9, on which a belt with adhesive strips 10 is wound. A second spool 11, which is driven by an electric motor connected to the control device SE, unwinds the tape with the adhesive strips 10 in accordance with the control commands of the control device SE. In this case, the tape with the Kle ^¬ stripe 10 is guided parallel to the subsidized by the main conveyor mechanism Sl component belt 2. To an access ^¬ point 12 of the feeding device 1 is a guide channel for the conveyed from the main conveying mechanism Sl Bauelemen ^¬ tegurte 2 accessible from above, whereby the adhesive tape 10 by means of a connected to the control unit SE Press¬ work from above on the cover films 7 of two in immediate succession befindlichem component straps 2 can be pressed. Thus, the covering films 7 can be glued together so that the stripping device of the feeding device 1 can operate automatically and without intervention by the operator.

In the following, the operation of the Darge in Figure 1 is presented feeding ^¬ 1 and an embodiment of the inventive method described for feeding of components in a feed. 1 Before starting up the feed device 1 a first component tape 2 and the second Hilfsförderme ^¬ mechanism S3, a second component tape 2 is fed through the two feed chutes 4 open the first auxiliary conveyor mechanism S2. The first auxiliary conveyor ^¬ mechanism S2 leads to the main conveyor mechanism Sl to the first component belt 2. As soon as the first component belt 2 is engaged with the main conveyor mechanism S1, the main conveyor mechanism S1 takes over the further transport of the first component belt 2 and the first auxiliary conveyor mechanism S2 is switched passively by the control device SE and is carried along by the first component belt 2. The Hauptför ^¬ the mechanism Sl supports the first component tape 2 so long in the conveying direction to the first component to the pickup position 3 positioned. Before the operator has the cover 7 of the first component belt with the ex ^¬ pulling device of the feeder 1 are brought into engagement. When picking the Bestückvorganges picks ^¬ head of the feeder 1 fetches the components from the first component belt 2 from. As soon as a component has been picked up, the main conveyor mechanism S1 is controlled by the control device SE in such a way that it continues to transport the first component belt 2 in the conveying direction such that the following component arrives at the pickup position 3.

After a certain number of pickup operations, the first individual detection device OS2 detects the end of the first component belt on the first auxiliary conveyor mechanism S2. The display device AE coupled to the first individual detection device OS2 informs the operator by means of an optical signal that the first component strap 2 is running out and a new component strap 2 has to be inserted into the first auxiliary conveying mechanism S2. Before the tracking of the new component tape, the provisions reviewed determining unit 6, for example, one based on the construction ^¬ elementegurt 2 attached bar codes, whether the type of nachzuführenden components coincides with the time required for the mounting operation type of devices. In a positive result of the determination, the control device SE opens the closure device on the feed chute 4 of the first auxiliary conveyor mechanism S2, and the new component belt 2 can be tracked. In this case, the new component belt 2 is fed to the first auxiliary conveying mechanism S2, which retracts it and holds it in a waiting position.

After the placement head has removed so many components from the first component strap 2 that the end of the first component strap mente belt 2 reaches the first joint detection device OSI, so it detects the end of the first Bauelemen ^¬ tegurtes 2. After the detection of the end of the first Bauele ^¬ mente belt 2, the control unit SE to the second held in the waiting position the second auxiliary conveyor mechanism S3 in such a way that this the second component tape 2 UNMIT ^¬ telbar following the end of the first outgoing Bau¬ elements the main conveyor belt 2 feeds mechanism Sl. The approach of the second component belt 2 to the end of the first expiring component belt 2 is in turn recognized by the common detection device OSI. Is promoted because, in this state, the first component tape 2, nor of the main conveying ^{mechanism at} Sl, and the second component tape is fed from the second auxiliary conveyor mechanism S3 2, the control unit SE synchronizes the second auxiliary conveyor mechanism S3 with the main conveying mechanism Sl. The second component tape 2 is supplied to the main conveying mechanism Sl during the same delivery stroke and at the same feedrate thus supplied ^¬ resulting in that the distance between the last component is located on the first component tape 2 th to the ers ^¬ that are on the second component tape 2 Bau¬ element equal to the distance between the components located on the first component belt 2 is. This ensures that even at the transition point between the first and the second component belt 2 the same component grid is held, as it already prevails on the first component belt 2. As soon as the first component belt 2 runs out of the main conveyor mechanism S1, ie as soon as the first component belt 2 is no longer in engagement with the main conveyor mechanism S1, the main conveyor mechanism S1 takes over the transport of the second component belt and the second auxiliary conveyor mechanism S3 is switched passively by the control device SE, ie he is dragged by the Hauptfördermechanis ^¬ mus Sl.

Even before reaching the removal device, not shown, for the cover foils 7 of the component straps 2, the abovementioned Cover films 7 of the first and the second component belt connected to the interface of the two component straps 2 by the connecting device 8 of the feeder 1. For this purpose the control unit SE controls the motor-driven coil, the connecting device 8 so that a Klebe¬ strip 10 to the access point 12 to the feed channel of the construction elements ^¬ belt 2 is transported out. As soon as the ^interface between the first component belt 2 and the second component belt 2 appears at the access point 12, the control device SE activates the pressing plant PW of the connecting device 8 such that it presses the adhesive strip 10 onto the cover films 7 of both component belts 2 and these glued together. This ensures that even without external intervention by the operator, the automatic removal of the cover sheets 7 continues to function smoothly.

After a certain number of removal operations by the placement head then again reaches the end of the second Bau ^¬ elementegurtes 2 the second individual detection device OS3, this reaching the end of the second

Bauelementegurtes 2 both the control device SE and the display device AE reports. The display device AE then in turn gives the operator an optical signal that the second component belt 2 comes to an end, so that this, as already described for the first auxiliary conveyor S2, inserts a new fourth component belt 2 into the second auxiliary conveyor mechanism S3. As already when adding a new third component tape 2 on the first Hilfsförderme ^¬ mechanism S2, the determining means also checked here 6, whether the nature of the components of the new fourth fed component tape 2 responds ent of the type of components required. If the check is positive, the control device SE opens the closing device of the second auxiliary conveying mechanism S3 and the operator can insert the new fourth component belt 2 into the auxiliary conveying mechanism. This is then eingezo ^¬ gene by the second auxiliary conveyor S3 and held in a waiting position. Then runs after a certain time of the second components ^¬ belt 2, ie, its end is detected by the common Erfas ^¬ sungseinrichtung OSI can immediately after the end of the second component tape 2 of the third construction ^¬ elementegurt 2 through the first auxiliary conveyor mechanism S2 the Main feed mechanism Sl are supplied and a new Zyk ^¬ lus can begin.

The above description shows that with the feed device 1 according to the invention and the method according to the invention a smooth operation of the feed device 1 is possible. The fact that constantly a second component strap 2 is kept ready in a waiting position, the operator has enough time to insert a new component strap 2. The operator is informed early on the leakage of one of the Bauelemen ^¬ tegurte 2. This increases the operational reliability ei ^¬ ner assembly plant significantly. Furthermore, in the feeding device 1 according to the invention, it is not necessary to splice the ends of an outgoing component ^strap together with the beginning of the after-guided component strap. Furthermore, the connecting device 8 ensures that the cover ^foils 7 of an outgoing and of the tracked component strap are connected to one another, so that the removal of the cover foils 7 can take place automatically and without external intervention by the operator. The determination device 6 prevents the operator from inserting incorrect component straps 2 into the feed device 1. All these measures increase the reliability of the feeder 1 considerably.

The common detection device OSI is arranged at a precisely defined distance a, which may be, for example, a multiple of the distance between the components and the component belt 2, from the pickup position 3. The distance b of the components on the component belt 2 is known. As soon as the common detection device OS1 detects the end of the first or second component belt, the control unit calculates Direction SE from the following formula, the number N _Res t of Bauele ^¬ elements, which are still between the common Detektorsein¬ direction OSI and the pickup position 3:

As a result, it can later be exactly understood which of the components installed by the placement machine are to be assigned to which building elements 2. This allows the up the most frequently demanded accurate traceability of all installed Bauele ^¬ mente be guaranteed accurate.

A second embodiment of the feeding device 1 according to the invention will be explained with reference to FIG. The second embodiment differs from the first exporting approximately ^¬ for example in that it means no common detection ^¬ comprises OSI. When operating this feeder 1, the end of the first component belt is detected only by the first individual detection device OS2 and the end of the second component belt by the second individual Er ^¬ detection device OS3. The first and second in¬ dividual detecting means OS2, and OS3 are arranged is at a known distance to the main conveying mechanism Sl ^¬, still may be so calculated accurately at a known distance of the components on the component tapes of the control unit SE, many feed clocks the En ¬ de of the first and second component belt 2 has arrived at the main ^¬ conveying mechanism Sl. Thereby, the control ^¬ means SE to the respective other so ansteu ^¬ ren in waiting position gehalte- NEN first or second auxiliary conveyor mechanism S3 that it the first and second component belt 2 directly after the end of the outgoing first and second Bauelementegurts 2 the main conveying mechanism Sl feeds. An ^¬ otherwise the method described above for conveying component straps is also valid for this second embodiment of a feed device 1 according to the invention. LIST OF REFERENCE NUMBERS
