Definitions
- Transport device for transporting and depositing thin-film elements and method
- the invention relates to a transport device for transporting and depositing thin-film elements, in particular fuel cell stack elements, and a method for transporting and depositing thin-film elements with a transport device.
- stack elements consisting of thin-film elements are stacked to form a fuel cell stack.
- a thin-film element can be, for example, a membrane-electrode assembly—abbreviated to MEA—or a bipolar plate—abbreviated to BPP.
- MEA and BPP are stacked alternately between the top and bottom cover plates.
- the stacking process is expediently carried out in the vertical direction; However, it is also conceivable to place BPP and MEA horizontally next to one another.
- the number of stacked fuel cells depends on the performance to be provided by the "stack" and can be in the order of up to 600 parts with an overall height of around 680mm.
- the MEA and the BPP are of different types, which is particularly evident in the fact that the MEA is very pliable and flexible, while the BPP has a much higher flexural rigidity, which is due to the fact that the BPP consists of a metallic material and is usually thicker than the MEA.
- a BPP can also be made from a graphite-like material and the MEA from a silicon-like material.
- fuel cell stacks can be manufactured using two different processes. On the one hand, stacking, pressing and final assembly of tension elements can take place in one device. The fuel cell stack is then removed from the device and transported to the final assembly. On the other hand, the fuel cell stacks can be stacked in a device. The fuel cell stacks are then transferred to a press that is attached to a handling device such as a robot. The stacks, including the press, are then transferred to a device for assembling tension elements. This is followed by transport to final assembly.
- Both processes alternately stack the BPP and MEA until the required “stack” height is reached.
- the MEA When handling the MEA, it is necessary to take into account its low inherent stability in order not to damage it. From the point of view of In the overall process, the BPP and MEA are initially available as individual, non-precisely positioned individual elements. It is therefore necessary to bring each of these elements into a dimensionally accurate position by appropriate handling, from which they can be stacked while maintaining the positioning to form a fuel cell stack, this stacking inherently involving an alternating arrangement of BPP and MEA.
- the stacking of MEA and BPP to form the "stack" and the simultaneous alignment of the MEA and BPP in the reference position to each other requires a comparatively high level of equipment and process engineering effort, which runs counter to the overriding goals of increasing the number of pieces with a simultaneously reduced cycle time.
- the object of the present invention is to provide a simplified sub-process for handling the thin-film elements in the sense of what is described above, in order to bring them into a dimensionally accurate position for subsequent stacking in this sub-process.
- a transport device for transporting and depositing thin-film elements, in particular fuel cell stack elements, with a plurality of conveyor belt-based transport routes arranged parallel to one another and extending in a transport direction R T , an eccentric drive unit with eccentric elements, with eccentric elements each in a starting area and an end area of each transport section are in a drive connection with this in order to cause vertical movements of the respective start area and end area of the transport sections via the eccentric drive unit in relation to the transport direction R T , with adjacent transport sections executing vertical movements offset in time.
- the transport device With the transport device according to the invention, it is possible to transport several thin-film elements at a time due to the opposing vertical movements of different transport sections. About the vertical movement, it is possible Release transport routes from the thin-film element, which is transported by another transport route. This makes it possible to impress different movement profiles in the direction of transport on the thin-film elements transported on different transport routes.
- the eccentric elements can be, for example, rotating cams or eccentric contours.
- eccentric elements are arranged on two synchronously driven eccentric shafts.
- the eccentric shafts can also be referred to as camshafts if the eccentric elements are designed as cams.
- a uniform vertical movement can be imposed via eccentric elements. It is also possible via the eccentric elements to realize different profiles for the vertical movement between the transport sections.
- An advantageous embodiment of the invention provides that the eccentric elements transmit the vertical movements to a respective deflection roller at the beginning and end of the conveyor-belt-based transport routes.
- a sufficient pivoting movement can be initiated in each of the transport sections by means of these points of attack, which are located extremely far from the outside.
- the deflection rollers are part of the load-bearing structure of the transport sections, so that no further stabilizing measures are required for these points of contact.
- An advantageous embodiment of the invention provides that a transport section has a plurality of conveyor belts that are arranged parallel to one another and are driven synchronously. As a result, the support surface for the respective thin-film elements is divided up, so that the thin-film elements can be larger in terms of surface area than the pure support surface and still rest stably and securely.
- An advantageous embodiment of the invention provides that a suction device is connected to an inner volume of the conveyor belts in order to cause suction of the thin-layer elements on an outside of the conveyor belts.
- a suction device is connected to an inner volume of the conveyor belts in order to cause suction of the thin-layer elements on an outside of the conveyor belts.
- An advantageous embodiment of the invention provides that the conveyor belts of different transport routes are alternately arranged adjacent to one another. This alternating arrangement of the transport paths makes it possible for all thin-film elements to be transported over the same transport path, ie to be transported within the same lateral boundaries, even if they run over different transport paths.
- An advantageous embodiment of the invention provides that a further drive unit for driving a conveyor belt of the transport route is provided for each of the transport routes. This makes it possible to drive the transport sections independently of one another.
- a transport speed of each of the transport sections can be regulated independently and steplessly via the corresponding drive unit.
- the transport speed of each transport section can be regulated until it comes to a standstill.
- each of the transport sections forms an essentially horizontally aligned transport plane on its underside.
- the transport plane formed on the underside of the transport sections is advantageous in that the thin-film elements can be transferred at the end of the transport section from the transport plane directly down into a stacked workpiece carrier of whatever type for stacking the thin-film elements. At this point it could also be said that the thin-film elements are ejected from the transport plane in the direction of the stacked workpiece carrier.
- an advantageous embodiment of the invention provides that at least in some areas a level blowing device is directed parallel to the transport plane.
- This blowing device can be provided either as an alternative or in addition to the suction of the thin-layer elements onto the conveyor belts, which has already been described as advantageous.
- An advantageous embodiment of the invention provides that an alignment funnel parallel to the transport plane is arranged at least in some areas in the area of the underside of the transport sections.
- a double funnel is preferably integrated into the alignment funnel, so that the thin-film elements pass through both funnels one after the other in the direction of fall.
- the alignment funnel makes it possible to finally bring the thin-film elements into the position in which they are deposited or stacked in the stacked workpiece carrier. Since each thin-film element is guided through the alignment funnel, the thin-film elements are all given the same absolute alignment, so that after they have been placed on the fuel cell stack, they are all positioned exactly to one another.
- the alignment funnel comprises a frame on the inner circumference of which a plurality of centering lugs are arranged.
- the funnel shape can be realized via the majority of the centering lugs.
- the centering lugs continue to approach the final positioning dimension as they pass through the funnel, which is referred to as the principle of the double funnel.
- the centering lugs can be attached in particular releasably, for example with a Screw connection so that they can be changed if necessary, for example when processing thin-film elements with different dimensions.
- An advantageous embodiment of the invention provides that a push-off device is arranged on the upper side of the transport sections opposite the aligning funnel, which can be moved vertically from the upper side of the transport sections and can pass through the transport plane in a lower end position.
- the piercing element which is effective from the top of the transport paths, makes it possible to eject the thin-layer elements downwards in the direction of the stacked workpiece carrier on the transport plane, which lies on the underside of the transport paths.
- a blow-off device can also be provided, the blow-off nozzles of which are directed vertically downwards through the transport sections in order to eject or blow off a thin-layer element vertically downwards.
- the object is also achieved by a method for transporting and depositing thin-film elements, in particular fuel cell stack elements, in which a transport device with a plurality of conveyor-belt-based transport routes arranged parallel to one another and extending in a transport direction R T is provided, mutual picking up of a first thin-film element from a first transport section and a second thin-film element from a second transport section and the thin-film elements are picked up by the respective transport section at a transport speed and are transported along the transport section with a reduction in the transport speed and are ejected after each passage through the transport section, with the ejection of one of the Thin-film elements takes place with the simultaneous recording of another thin-film element and a starting area and an end area of each transport section during the transport of a thin-film element in each case perform vertical movements in a vertical direction R v oriented perpendicularly to the transport direction R T , the vertical movements of the start regions and end regions of the transport sections being offset in time with respect to the vertical direction R v in accordance with
- An advantageous embodiment of the method provides that, via the vertical movements, both the initial area of the transport sections for receiving a thin-film element and the end area of the transport sections for ejecting a thin-film element are lowered, in particular lowered alternately, relative to an essentially horizontal transport plane formed by an underside of the transport sections .
- the transport speed for ejecting a thin-film element is reduced until it comes to a standstill.
- An advantageous embodiment of the method is characterized by the generation of the vertical movements by a counter-rotating vertical up and down movement of the respective start area and end area of the transport sections.
- FIG. 1 shows an overall system with a transport device according to the invention in a schematic representation
- FIGS. 2 to 4 show a transport device according to the invention in various representations
- FIGS. 5a), 5b a transport device according to the invention and a transport of thin-film elements in two representations
- FIG. 6 shows an illustration of one downstream of the transport device
- FIG. 7 shows a detail of the transport device.
- FIG. 1 first shows a possible overall system 1, within which a transport device 10 according to the invention is arranged.
- the overall system 1 is only an exemplary configuration of such a system.
- the overall system 1 initially has a conveyor belt 4 onto which the thin-film elements 2 are placed at equal time intervals, so that the thin-film elements 2 have the same spacing, subject to tolerances, in the transport direction R T .
- the thin-film elements 2 successively pass through an alignment unit 6, which preferably has a conveyor belt on each side.
- the thin-film elements 2 experience a final alignment via the alignment unit 6, namely with regard to their distance from one another in the transport direction R T and with regard to their perpendicular position to the transport direction R T .
- the thin-film elements 2 are transferred from the conveyor belt 4 to the transport device 10 according to the invention; a process that will be described in more detail later. After passing through the transport device 10, the thin-film elements 2 are pushed off the transport device 10 or ejected in an end region of the transport device 10 via a push-off device 50. The discharge can also be carried out by blowing off using one or more blowing nozzles.
- the thin-film elements 2 pass through an alignment funnel 40 through which they have another experience dimensionally accurate positioning before they are stacked in the stack workpiece carrier 8 to form a fuel cell stack, which does not require a more detailed explanation here.
- FIG. 2 shows a transport device 10 according to the invention in a side view
- FIG. 3 shows the transport device 10 in a perspective view.
- the transport device 10 has two transport paths 12i and 12 2 which each form a transport plane 18 on an underside.
- One transport route 12i includes two conveyor belts 13 and the second transport route 12 2 includes three conveyor belts 14. All conveyor belts 13, 14 are arranged parallel to one another.
- the conveyor belts 13, 14 of the two transport sections 12i, 122 are arranged alternately adjacent to one another, which can be seen in FIG.
- a separate drive unit 16i, 16 2 is provided for each of the conveyor belts 13 , 14 of the two transport routes 12 i , 12 2 .
- the drive units 16i, 16 2 are preferably arranged above the transport routes 12i, 12 2 and each have a drive shaft 26i, 26 2 , via which the conveyor belts 13, 14 are guided over it for the drive connection.
- a clamping device 28 is provided for each conveyor belt 13, 14 .
- the transport device 10 includes an eccentric drive unit 20 with eccentric elements 22, the eccentric elements 22 being part of two eccentric shafts 24 in the present case. It can be provided that one eccentric shaft 24 is driven directly by a drive motor and the other eccentric shaft 24 indirectly, for example via a drive belt. Both eccentric shafts 24 are driven synchronously and with a 1:1 translation with an angular offset with the same eccentric stroke.
- the eccentric shafts 24 are held in respective bearing blocks 32i, 32 2 .
- the arrangement of bearing blocks 32, the eccentric shafts 24, the eccentric elements 22 and transmission tappets 34, which produce the mechanical operative connection between the eccentric elements 22 and the conveyor belts 13, 14, is preferred both in a starting area and in an end area of the transport sections 12i , 12 2 provided. Consequently, this arrangement is duplicated.
- the second and fourth eccentric element 22 on each eccentric shaft 24 is assigned to the conveyor belts 13 and the first, third and fifth eccentric element 22 on each eccentric shaft 24 is assigned to the conveyor belts 14 .
- a suction device 36 is provided, which is connected via a vacuum line to an interior of pipe sections 37i and 372 and via which a vacuum can be generated within the conveyor belts 13, 14.
- the material of the conveyor belts 13, 14 is designed to be air-permeable, it is possible to suck a thin-layer element 2 onto the corresponding conveyor belt. It can be seen in FIG. 3 that the piece of pipe 371 forms through-grooves in an inner volume of the conveyor belts 13 so that the negative pressure generated can form in the conveyor belts 13 . Likewise, the piece of pipe 37 has 2 through-grooves for forming the negative pressure in the conveyor belts 14 .
- a control and regulation unit 48 is also outlined in FIG . Via the control and regulation unit 48 it is preferably possible to control or regulate the drives 16 and 24 with regard to their rotational speed but also with regard to a rotational speed profile.
- a speed profile is to be understood in particular as a change in the speed over a period of time, it also being possible for a speed of zero to be part of the profile.
- the conveyor belt 4 is preferably also included in this control or regulation.
- the transport device 10 comprises a base frame, not shown here, on which immovable parts are held and are carried out relative to the movements of the moving parts.
- the bearing blocks 32i, 32 2 are held stationary on the base frame.
- An eccentric shaft 24 is mounted in each of the bearing blocks 32i, 32 2 and can be driven in rotation. In the present case, five slide or roller bearings are provided for supporting the eccentric shaft 24 .
- the eccentric elements 22 are arranged on the eccentric shaft 24 between the sliding or roller bearings.
- Each eccentric element 22 is operatively connected to a transmission ram 34 according to the principle of a crankshaft, with each transmission ram 34 being connected to a deflection roller 15 at the end of each conveyor belt 14 .
- each of the eccentric elements 22 located on it By rotating the eccentric shaft 24, each of the eccentric elements 22 located on it also rotates, so that the transmission plungers 34 connected to the respective eccentric element 22 are forced into a lifting movement or vertical movement. This movement is transmitted to the corresponding conveyor belt 14 via the connection between the transmission plunger 34 and the respective deflection roller 15 .
- the movement profiles imposed by the eccentric drive unit 20 on the transport routes 12i, 12 2 , and thus their respective conveyor belts 14, can be described as follows:
- the starting area and the end area of one of the transport routes 12i, 12 2 always perform an opposite vertical movement. That is, if the beginning area moves vertically upwards, the end area moves vertically downwards in the opposite direction.
- the other transport section 12 2 , 12i now moves in the opposite direction overall. That is, when the beginning portion of the first transportation path 12i moves vertically upwards, the beginning portion of the second transportation path 12 2 moves vertically downwards. Consequently, the end regions of the two transport paths 12i, 12 2 move in opposite directions.
- This movement profile is not just a pivoting movement about a central pivoting axis of the transport sections 12i , 122. Rather, the mutual vertical movement of each transport path 12i, 12 2 results in a movement profile in which the two transport paths 12i, 12 2 lie in two horizontal planes that are vertically spaced from one another at the time when they are both exactly horizontal. As will be described later, this is crucial because both transport sections 12i, 12 2 have different transport speeds during their vertical movements, so that it must be ensured that a thin-film element 2 transported from one transport section 12i, 12 2 does not come into contact with the other transport section 12 2 , 12i is coming.
- This movement profile is provided both for a transport path 12i, 12 2 as a whole and for each of its conveyor belts 13, 14. It has already been explained that, starting from the relevant eccentric element 22 , the vertical movement is transmitted to the corresponding conveyor belt 13 , 14 via the connection between the transmission plunger 34 and the respective deflection roller 15 .
- the eccentric elements 22 of the other transport section 12 2 are oriented offset on the respective eccentric shaft 24 at the beginning and end, compared to the eccentric elements 22 on the same side of the first transport section 121 .
- a driven rotation of the eccentric shafts 24 consequently causes a vertical movement of both transport sections 12i and 12 2 at the beginning and end, which, however, runs in opposite directions with respect to its direction of movement between transport sections 12i, 12 2 .
- FIG. 5a) shows how a thin-film element 2 was initially transported to the transport device 10 via the transport belt 4.
- the conveyor belt 4 ends at an underside of the transport device 10.
- the transport plane 18 of the transport device 10 is located on this underside, so that the thin-film elements 2 are transferred from the conveyor belt 4 to the transport plane 18.
- a blowing device 30 is located in this area of the transport plane 18. The blowing device 30 is therefore directed at least in some areas against the underside of the transport paths 12.
- the blowing device 30 is fed in a suitable manner with an air flow which, as a result of at least a slight overpressure, blows off upwards through outlet openings in the direction of the transport plane 18 .
- a thin-layer element 2, which is located in the space between the blowing device 30 and the transport plane 18, is consequently applied upwards against the conveyor belts 14 of the transport sections 12 due to its low weight and its areal extent.
- the thin-film element 2 is caught by the action of the blowing device 30, steamed up into the transport plane 18 and taken over by the moving conveyor belts 14 and transported further.
- the already described suction device 36 of the conveyor belts 13, 14 can also be used here, but this will not be discussed again at this point.
- the conveyor belt 4 and the conveyor belts 14 preferably have the same conveying speed, which can also be referred to as the transport speed.
- the conveyor belts 14i and 14 2 of the first transport section 121 are positioned vertically downwards in the initial area via the eccentric drive unit 20 .
- the starting area of the conveyor belts 14 3 to 14 5 of the second transport section 12 2 is then positioned vertically upwards, so that the conveyor belts 14 3 to 14 5 of the second transport section 12 2 cannot come into contact with the thin-film element 2 that has just been accepted .
- a thin-film element 2 does not come into contact with the other transport path 12 2 , 12 1 after it has been taken over and during transport through one transport path 12 1 , 12 2 .
- FIG. 5b shows how the first thin-film element 2i was transported along the first transport route 12i to the end area. Meanwhile, the conveyor belts 14i, 14 2 of the first transport section 12i have been placed vertically upwards in the initial area and vertically downwards in the end area via the eccentric drive unit 20 . The first thin-film element 2i is now located above the aligning funnel 40 and is ejected vertically downwards out of the transport plane 18 by the ejection device 50 (not shown here), see FIG. 1, symbolized by the two arrows pointing downwards.
- the repelling device can be designed mechanically as a piercing element or as one or more blowing nozzles.
- FIG. 6 shows the alignment funnel 12 as a detail, through which the thin-film elements 2 receive a further dimensionally accurate positioning after they have left the end position of the transport device 10 in a vertical downward direction.
- the alignment funnel 12 is designed as a double funnel, in which a dual alignment function is integrated.
- the alignment funnel 40 comprises a frame 42 on the inner circumference 44 of which a plurality of centering lugs 46 are arranged.
- An alignment contour for the thin-film element 2 is impressed on the alignment cone 40 via the centering lugs 46 and 47 on the inner circumference 44 .
- two different designs of centering lugs 46 and 47 can be used.
- each thin-film element 2 is pre-centered by the wider centering lugs 46, so that the alignment of the respective thin-film element 2 is sufficient to allow a second final alignment to take place in the centering lugs 47 that are located further below and taper to a point during the downward movement of the thin-film element.
- FIG. 7 shows a further detail of the transport device 10.
- a crank-driven deceleration stop 52 is shown, which comprises a stop element which can be brought into a position in the end regions of the transport paths 121, 122 by means of a crank.
- the stop element is able to prevent further transport of the respective thin-layer element 2 so that the thin-layer element 2 is stopped exactly above the aligning funnel 40 and can be ejected from the transport device 10 .
