Description

[0001] The invention relates to a system for the inline production of a lightweight component in hybrid construction in the form of a vehicle body to be provided with hybrid structures, comprising a transport device which is movable in the direction of a production line which comprises cathodic dip painting, painting and final assembly as process stages, on which transport device a metallic component structure or the vehicle body can be conveyed along the production line, a plastics processing unit in the form of an injection molding machine having at least one injection molding unit, from which a thermoplastic and / or thermosetting material is to be provided, and a control system by which the movement of the transport device and the at least one injection molding unit as well as the provision of the thermoplastic and / or thermosetting material by means of the injection molding machine can be controlled according to a control program.

[0002] From DE 10 2014 012 204 A1, a plant for producing a composite, in particular a forming plant, is known, with which a fiber-reinforced semi-finished product (base carrier) is to be specifically reinforced “inline” with a second fiber-reinforced semi-finished product (reinforcing element).

[0003] Lightweight components made from a galvanized iron base body with reinforcing structures, wherein the reinforcing structures are firmly bonded to the base body and formed from molded-on thermoplastics such as polymer molding compounds, e.g., polyamides, are known from DE 10 2008 058 225 A1. The secure form fit between the molded-on thermoplastic and the base body can also be achieved via discrete connection points via openings in the base body, through which the thermoplastic extends and beyond the surface of the openings. Such lightweight components are preferably used in motor vehicles, among other applications.

[0004] Lightweight components in hybrid construction can usually be characterized by the form fit of a metallic base body and a plastic part inserted or attached to it.

[0005] WO 2002 / 068257 discloses so-called integrated structures made of metal and plastic with the description of numerous fastening means to firmly connect both components.

[0006] In addition, it is known from WO 2004 / 071741, according to which a shell-shaped metal part is first injected with plastic in two work steps in such a way that the plastic passes through openings in the metal part and leaves burrs on the other side, which only have to be processed into a firm form fit in an additional work step.

[0007] EP 1 032 526 B1 further discloses a support structure for the front module of a motor vehicle comprising a sheet steel base body, an unreinforced, amorphous, thermoplastic material, a glass fiber reinforced thermoplastic material and a rib structure made of, for example, polyamide.

[0008] DE 10 2011 100 050 A1 also discloses a support element, in particular a roof bow for a motor vehicle body, with at least one shell part and a stiffening structure made of plastic that is injection-molded in a cavity of the shell part, wherein the shell part is made of an organic sheet.

[0009] After its production in a separate first process step, this support element or roof bow is bonded to a body part in at least one separate second process step using an adhesive absorbed in a groove of the shell part. Alternatively, a metal attachment piece can be attached to the support element in a second process step following its production, with which the support element can be welded into the vehicle body. In this case, the support element can be mounted in the vehicle body with a hollow space open at the bottom.

[0010] The complete support element or roof bow can be mounted to two longitudinal members of a vehicle body's roof frame using the metal attachment pieces attached to each end. The contours of the two metal attachment pieces are joined in a form-fitting manner with the complementary contours of the longitudinal members at the roof bow's precisely intended installation position. The metal attachment pieces allow the roof bow to be mounted to the longitudinal members just like a conventional sheet metal roof bow, using welding, riveting, or other methods familiar to the expert.

[0011] DE 10 2006 048 400 A1 also discloses an injection molding machine for thermoplastic plastic with devices for plasticizing the plastic and for injecting the plasticized plastic through an injection nozzle into a mold. The injection nozzle is adjustable in several directions relative to the mold, and the device for plasticizing the plastic and the device for injecting the plastic can be pressed against one another and separated from one another, and the separate injection device can be moved by a handling device. Here, the device for plasticizing is stationary, and the device for injecting the plastic can be moved toward the mold by a conventional industrial robot as a handling device.

[0012] DE 10 2011 001 516 A1 also discloses an arrangement for producing transport pallets made of plastic. This arrangement includes at least one stationary pouring station for filling at least one closed mold with plastic, as well as a transport device for the automated transport of the at least one mold from the stationary pouring station through a cooling area to a demolding station and back to the stationary pouring station.

[0013] US 2014 / 0128811 A1 discloses an array of microneedles made of polymeric material, comprising a plurality of microneedles with a height between 20 and 1,000 µm and an aspect ratio greater than 2:1 based on an area, wherein at least 60% of the microneedles are filled across the array, in the sense that the mold cavities of the microneedles, which serve to form the microneedles, have been filled with polymeric material to form the complete microcells. An embodiment of an injection molding system used for this purpose comprises a hopper for the material to be plasticized, such as plastic pellets or metal pellets embedded in plastic, a heating chamber for melting and feeding the material, a first mold element, and a second mold element in which an ultrasound-generating horn is installed.The first mold element is stationary, but can also be movable, and the second mold element can be moved back and forth with respect to the first mold element.

[0014] The injection molding system further comprises a system for dividing a carrier web or film. The system is equipped with a feed roller, a take-up roller, a tension roller, and a number of guide rollers between the feed roller and the take-up roller, and with which the carrier web can be moved back and forth between the first mold element and the second mold element. For example, using a spray nozzle of the first mold element, injection-molded elements can be injected at intervals on a first side of the carrier web. However, the injection molding of plastic elements on both sides of the carrier web is possible with this injection molding system.

[0015] Traditionally, for example, manufactured plastic components and assemblies in the automotive industry, as well as manufactured hybrid components and assemblies, are delivered by system manufacturers to the production line and assembled there by the OEM. These assembly processes involve logistical, personnel, and machine costs. The delivery of vehicle components, whether individual parts or assemblies, to the final assembly line and their assembly there are characterized by assembly costs, e.g., during joining, logistics costs, and quality control measures such as dimensional control, material testing, and testing of additional optical and tactile properties according to the specifications.

[0016] Document JP 5417549 B1 further describes a system comprising a cylinder with a conical attachment on a first side of the cylinder, the attachment containing a nozzle. The cylinder further comprises a plastic pellet feeder and a plastic pellet melting device. The system can be used to produce components of a hybrid design.

[0017] US 2007 / 0029700 A1 also discloses a control system with molds for film formation in the vacuum stage, for example, for the inline production of lampshades in hybrid construction. Using a movable mold, a metallic lamp body can be produced by injection molding and / or encapsulation with thermoplastic and / or thermosetting material, which can be provided and plasticized by a plastics processing unit such as an injection molding machine. The injection molding machine can be integrated inline within a production line locally and / or temporarily and / or within a work cycle.

[0018] DE 10201 014 504 A1 also discloses a system for producing a body of a passenger car, by means of which a plurality of body components, which are at least partially covered with a plastic, can be connected to one another. The system comprises respective devices for internal high-pressure forming and injection molding, by means of which the body can be produced in a combined internal high-pressure forming and injection molding process.

[0019] The invention is based on the object of providing a system for the inline production of a lightweight component in hybrid construction in the form of a vehicle body to be provided with hybrid structures, which ensures an increase in inline production effectiveness and accuracy by reducing the conventional technical coordination and assembly effort.

[0020] In addition, variable process integration in the production line should be enabled and, for example, in the production of a vehicle body to be provided with hybrid structures, areas of the latter should be functionalized directly in the production process without assembly and tolerance-compensating functional elements should be able to be integrated or mounted.

[0021] The object underlying the invention is achieved according to the invention by a system of the type mentioned at the outset in which the plastics processing unit or the injection molding machine or the at least one injection molding unit is connected to a mobile handling device or mobile automation unit and together with this can be positioned inline locally and / or temporarily within the production line parallel to the direction of movement of the transport device conveying the metallic component structure or the vehicle body and can be moved in a controlled manner relative to the metallic component structure or the vehicle body in the production process of the vehicle body to be provided with hybrid structures,wherein the plastic material provided by the plastics processing plant or by the injection molding machine or by the at least one injection molding unit is to be injected directly onto and / or into the metallic component structure or vehicle body conveyed on the transport device by means of the handling device or the automation unit and / or parts of the latter are to be at least partially overmolded, and the components and / or the plastic regions and / or the plastic structural semi-finished products as well as the metallic component structure are to be directly added to the vehicle body in hybrid construction.

[0022] Advantageous embodiments of the system according to the invention are characterized in that - the plastics processing unit is a plastics manufacturing cell, - the plastics processing unit or the plastics production cell or the injection moulding machine or the at least one injection moulding unit together with the mobile handling device or the automation unit is to be moved relative to the metallic component element or the vehicle body which is movable inline along an assembly line within the production line or is stationary within a work cycle in the production line, - the plastic components are sealing elements, damping elements, functional elements in the form of screw-on domes, clips and stiffening ribs, segments for integrating electronic elements in the form of sensors, antennas and / or signal transmitters as well as ventilation and venting ducts, as well as the plastic areas are mounting surfaces for bonding, surface sealing areas and the plastic structural parts in the form of organo-sheet metal structures or unidirectional tapes, textile reinforcements as well as duroplastic and / or thermoplastic reinforcements on the component structure, metallic component structure or the vehicle body, - in the body-mounted production of plastic parts, areas of the metallic or vehicle body form the tool counter support for the injection molding process.

[0023] The mobile handling device or automation unit comprises one or preferably a plurality of robot-supported, automated, 3D-movable injection molding units, each of which is automatically and variably equipped with the required injection molding tool in the production process according to the injection molding function to be performed. For this purpose, the handling device or automation unit preferably comprises a movable injection molding tool magazine in which a plurality of the required different injection molding tools are stored ready for use. The injection molding tools can also be provided by additional mobile handling devices.

[0024] By means of the system according to the invention, components made of plastic such as sealing elements, damping elements, functional elements such as screw-on domes, clips, stiffening ribs, segments for integrating electronic elements such as sensors, antennas and / or signal transmitters as well as ventilation and vent ducts, as well as areas made of plastic such as mounting surfaces for adhesives, surface sealing areas and structural parts made of plastic such as organo-sheet metal structures, unidirectional tapes (so-called UD tapes), textile reinforcements as well as duroplastic and / or thermoplastic reinforcements can be provided on the metallic component structure or the vehicle body, which are formed by direct injection molding and / or injecting of thermoplastic and / or duroplastic material and / or overmolding (bonding) of at least parts of the latter.In the body-mounted production of these plastic parts, areas of the metallic component structure or the vehicle body form the tool counter support for the injection molding process.

[0025] Due to the possibility of manufacturing the plastic components to be joined to the metallic component structure or the vehicle body close to final assembly, there is no need for component delivery, so that logistics costs as well as personnel costs for quality-related measures such as incoming goods inspection and for the assembly of the components to be delivered can be saved.

[0026] In addition, the manufacturing accuracy of the required joining processes increases, as vehicle areas subject to tolerances, such as the vehicle body, can be compensated. Subsequent assembly processes are more precise, and the design is simpler, as additional components for tolerance compensation are no longer necessary.

[0027] Manufacturing difficulties such as deformation of the vehicle body during electrocoating (ECD) can be avoided by injecting and / or overmolding plastic and creating suitable geometries that create partial reinforcement. Another advantage is that the system according to the invention can be integrated into various inline process stages, for example, before and / or after ECD or painting, and is not tied to cycle times at the optimal location on the production line. Structural semi-finished products such as organic sheets or UD tapes are to be bonded directly to the vehicle body. The corresponding areas are formed by injection molding, eliminating the need for tight-tolerance cutting or assembly aids.

[0028] The plastics processing unit or, for example, relevant components of the injection molding machine are positioned directly on the injection mold with the cavity and temporarily firmly connected to the latter. The injection mold encloses the area of ​​the component structure or vehicle body to be molded and / or overmolded, thus forming the pressure-tight cavity area into which the plasticized or liquid polymer is injected. The cavity area can be at least partially represented by the component structure or vehicle body and in combination with a tool mold. This allows the plastic material provided by the plastics processing unit or the injection molding unit of the injection molding machine to be injected directly onto and / or into the metallic component structure and / or parts of the latter to be at least partially molded onto and / or overmolded.

[0029] The plastics processing unit can be designed as a plastics production cell. Preferably, the plastics processing unit, the plastics production cell, or the injection molding machine is moved relative to the metallic component element or the vehicle body moving inline along an assembly line within the production line, or is attached to a mobile automation unit, such as a controlled robot, and can thus be precisely positioned in the production line in relation to the vehicle body in the processing area.

[0030] The handling device or automation unit can be designed as at least one robot-supported, automated, and 3D-movable injection molding unit. Preferably, the handling device or automation unit consists of a plurality of robot-supported, automated, 3D-movable units, allowing the injection molding units to be controlled, mobile, and flexibly positioned.

[0031] The vehicle body may also be temporarily stationary during injection molding or introduction of the polymer into the target area and at least temporarily not be moved relative to the mold of the injection molding unit.

[0032] Preferably, each injection molding unit can be automatically and variably equipped with the required injection molding tool in the production process according to the injection molding function to be performed.

[0033] Preferably, sealing elements, damping elements, functional elements such as screw-on domes, clips, stiffening ribs, segments for integrating electronic elements such as sensors, antennas and / or signal transmitters as well as ventilation and vent ducts are formed as plastic components, as well as mounting surfaces for adhesive bonds, sealing areas as plastic areas and as structural parts made of plastic, organo sheet structures, unidirectional tapes (so-called UD tapes), textile reinforcements as well as duroplastic and / or thermoplastic reinforcements on the metallic component structure or the vehicle body by direct injection molding and / or injection of thermoplastic and / or duroplastic material and / or overmolding (bonding) of at least parts of the latter.

[0034] In the body-mounted production of plastic parts, areas of the metallic component structure or the vehicle body can be used as tool counter support for the injection molding process.

[0035] The system according to the invention also allows certain interior components to be manufactured using the multi-component injection molding process, whereby optical and haptic effects can be realized, particularly for surface-sensitive components, without great handling effort and with relatively wide design freedom.

[0036] The present invention will now be explained with reference to the drawings, in which: Fig. 1 a schematic plan view of a production line for the basic representation of the system according to the invention for the inline production of a lightweight component in hybrid construction, such as a vehicle body to be provided with hybrid structures, Fig. 2 is a schematic perspective view of a vehicle body according to Fig. 1 can be provided with hybrid structures made of plastic, Fig. 3 a schematic sectional view of an embodiment of the system according to the invention, Fig. 4 a schematic sectional view of another embodiment of the system according to the invention, and Fig. 5 is a schematic sectional view of a detail of one of the embodiments according to Fig. 3 similar embodiment of the system according to the invention, wherein an injection molding process on the vehicle body is demonstrated.

The transport device 3 can be moved in the direction A of the production line 4 inline through stations of the production line 2, such as, for example, dip painting (KTL) for corrosion protection B, painting C, injection molding of plastic and joining D, and final assembly E. For the production of the lightweight component in hybrid construction or the vehicle body 1 to be provided with hybrid structures, a plastics processing unit or at least one injection molding unit or an injection molding machine 5 is arranged in the production line 2 inline locally and / or temporarily in the position D in Fig. 1 is positioned in a movably controlled manner relative to the metallic component structure or the metallic vehicle body 1 conveyed on the transport device 3. A thermoplastic and / or thermosetting material is provided by the plastics processing unit or the injection molding machine 5 or the injection molding unit. This can be implemented by means of a mobile automation unit connected to the plastics processing unit or injection molding machine 5, for example as a mobile injection molding unit 6.which is 3D-movably controllable by at least one robot, for equipping and / or reinforcing the metallic component structure or the metallic vehicle body 1 with components (elements) and / or regions made of plastic and / or semi-finished structural products made of plastic, which can be injected directly onto and / or into the metallic component structure or the metallic vehicle body 1 and / or can be injected at least partially around parts of the latter. At the same time, the components (elements) and / or regions made of plastic and / or the semi-finished structural products made of plastic, as well as the metallic component structure or the metallic vehicle body 1, can be directly joined to form the lightweight hybrid component or the vehicle body in a hybrid design.

[0038] Fig. 2 shows a schematic perspective view of a vehicle body 1, which is produced in the final assembly station E according to Fig. 1 in direction A of the production line 4 on the Fig. 2 not shown transport device 3 in the production process. A schematically shown mobile injection molding unit 6 equipped with an injection molding tool 7 as a handling device is connected to the Fig. 2 schematically illustrated plastics processing unit such as an injection molding machine 5, which according to Fig. 1 is positioned locally and / or temporarily within the production line 2 and is movable relative to the vehicle body 1 according to arrow a and arrow b, is movably coupled and is movable relative to the vehicle body 1 by means of a Fig. 2 robots not shown can be controlled automatically in 3D.

[0039] By directly molding and / or injecting the thermoplastic and / or thermosetting material provided by the injection molding machine 5 onto and / or into the metallic vehicle body 1 and / or overmolding (bonding) at least parts of the latter, as can be seen from Fig. 2, the metallic vehicle body 1 can be equipped and / or reinforced with components made of plastic such as sealing elements 9, damping elements 10, functional elements 11 such as screw-on domes, clips, stiffening ribs, segments 12 for integrating electronic elements such as sensors, antennas and / or signal generators as well as ventilation and vent ducts 13, with areas made of plastic such as mounting surfaces 14 for adhesives, with surface sealing areas 15, with structural parts 16 made of plastic in the form of organic sheet structures, unidirectional tapes (so-called UD tapes) and / or textile reinforcements as well as with duroplastic and / or thermoplastic reinforcements.

[0040] At the Fig. In the embodiment of the system according to the invention shown in Figure 3, the injection molding machine 5 is connected via a supply line 17 to a storage unit 19 holding a granulate 18 and is mounted on a sliding unit 20, which is guided on a sliding table 21 in a controllable manner by means of a control device 8. The sliding table 21 is in turn positioned on a machine frame 22, which is arranged within the production line 2 at a distance from and parallel to the assembly line 23. The vehicle body 1 is shown positioned on the assembly line 23, to which the injection molding machine 5 is controllably movable relative to it.An injection molding tool unit is replaceably mounted on a machine clamping plate 24 of the injection molding machine 5, said unit consisting of an injection-side injection molding tool 25 and a counter-injection-side injection molding tool 26, and is to be attached in a controlled manner to a section of the outer wall 27 of the vehicle body 1, forming a cavity 28 to be filled with plastic on the inside of the outer wall 27 of the vehicle body 1, and is to be actuated by means of a locking system 39.

[0041] Fig. 4 shows a further embodiment of the system according to the invention, which essentially corresponds to the structure of the embodiment of the system according to the invention according to Fig. 3. Here too, the injection molding machine 5 is connected via the feed line 17 to the storage 19 receiving the granulate 18 and is guided in a controllable manner within the production line 2 relative to the vehicle body 1 positioned on the assembly line 23. Likewise, the injection molding tool unit is interchangeably mounted on the machine clamping plate 24 of the injection molding machine 5. This unit consists of the injection-side injection mold 25 and the counter-injection-side injection mold 26 and is to be controlled and actuated by means of a locking system 39 on the inside of the outer wall 27 of the vehicle body 1 to form the cavity 28 to be filled with plastic 41.

[0042] In contrast to the embodiment of the system according to the invention according to Fig. 3 is, however, as can be seen Fig. 4, in the given case the injection moulding machine 5 can be moved in a controlled manner relative to the vehicle body 1 positioned on the assembly line 23 by means of a handling device acting on it in the form of a robot 29 which can be moved in a controlled manner within the production line 2, in such a way that the injection moulding tool unit which is to be exchangeably mounted on the machine clamping plate 24 can be used on the vehicle body 1 in an automated, 3D-movable manner.

[0043] Fig. 5, which is a sectional view of a detail of an embodiment of the system according to the invention similar to Fig.4 shows, demonstrates the injection molding process on a metal sheet 33 of the vehicle body 1, which is to be joined to a first profiled inner sheet 30 and to a second profiled inner sheet 31 and has beads 32. It can be seen that an injection molding tool unit communicating with the injection nozzle 35 of the injection molding machine 5 is mounted on the machine clamping plate 24 of the injection molding machine 5 by means of fastening screws 34, which injection molding tool unit is formed from an injection-side (nozzle-side) injection mold 36 and a counter-injection-side (counter-nozzle-side) injection mold 37, which are subjected to opposing clamping forces indicated by arrows Z during the injection molding process.At the same time, plastic 40 is injected with the injection nozzle 35 of the injection molding machine 5 onto the metal sheet 33 having beads 32 and the first profiled inner sheet 30 on the injection side, as well as onto the opposite side of the metal sheet 33 and the second profiled inner sheet 31, whereby the metal sheet 33 and the two profiled inner sheets 30 and 31 are joined together. By means of a spring ejector 38, the nozzle-side injection molding tool 36 and the counter-nozzle-side injection molding tool 37 are returned to their starting positions after the joining process.
