Definitions

  • the invention relates to a method for the automated attachment of insulating elements to structural elements of motor vehicles, and insulating elements for such a method.
  • components such as bodies and/or frames of means of transport and locomotion, in particular of vehicles on water or on land or of aircraft, have structures with cavities in order to enable lightweight constructions.
  • these voids cause various problems.
  • it must be sealed to prevent the ingress of moisture and dirt, which can lead to corrosion of the components.
  • It is often also desirable to significantly strengthen the cavities and thus the structural element, while maintaining the low weight.
  • It is also often necessary to stabilize the cavities, and hence the components, to reduce noise that would otherwise be transmitted along or through the cavity.
  • Many of these cavities are irregular in shape or narrow in size, making them difficult to properly seal, reinforce and cushion.
  • sealing elements are therefore used to seal cavities and/or acoustically seal them off, or reinforcing elements (English: reinforcer) are used to reinforce cavities.
  • a body of an automobile is shown schematically.
  • the body 10 has various structures with cavities, such as pillars 14 and supports or struts 12 .
  • Such structural elements 12, 14 with cavities are usually sealed or reinforced with insulating elements 16.
  • Such insulating elements 16 are usually attached to the structural elements 12, 14 by hand.
  • a disadvantage of this known manual method is that it requires a lot of work and that this manual work is often difficult to carry out from an ergonomic point of view.
  • there is the manual attachment the risk of insulating elements being placed in unintended positions, and also that incorrect insulating elements being placed in a position of a structural element.
  • the method should be more economical, avoid ergonomically unfavorable workplaces, and prevent the risk of incorrect installation as far as possible.
  • a method for the automated attachment of insulating elements to structural elements of motor vehicles comprising the steps: providing a plurality of insulating elements, with an insulating element each having a carrier, an expandable material which is arranged on the carrier, and at least one Fixing element for fixing the insulating element on the structural element comprises; Picking up individual insulating elements by a robot, the robot being designed as a multi-axis robot with a gripper; and the robot attaching an insulating element to a structural element in each case, with the at least one fixing element of the insulating element being introduced into an opening in the structural element.
  • this solution has the advantage that insulating elements can be attached to structural elements using an automated process. As a result, considerable costs can be saved, which are incurred when the insulation elements are applied manually. In addition, such an automated process can also rule out incorrect manipulations, which occasionally occur with manual applications.
  • the method proposed here also offers the advantage that the insulating elements themselves can be designed differently as a result of the automated attachment of the insulating elements.
  • the insulating elements must be designed in such a way that they can be easily attached by hand. This requires, for example, a special adjustment of fixing elements, so that a force is required for attachment of the insulating elements on structural elements does not exceed a certain value for ergonomic reasons.
  • the fixing elements can be designed in such a way that a higher level of force can also be used. This makes it possible, for example, to use cheaper or more robust materials for the fixing element.
  • the insulation elements for manual attachment often have to have special features so that incorrectly oriented alignment on the structural element during attachment is impossible. This can be achieved, for example, by a poka-yoke design of the fixing elements, which, however, increases the costs for such insulating elements. Such special features can be avoided by the automated attachment method proposed here, so that cheaper insulating elements can be used as a result.
  • insulating element includes elements for sealing off and/or insulating and/or damping and/or closing and/or reinforcing and/or insulating a structural element. These different properties of such an insulating element can occur individually or in combination with one another.
  • the designations “upper side” and “lower side” each mean the two main surfaces or the two largest surfaces of the insulating element. Since the insulating elements are designed to close a cross-section in a structural element, this means that the upper side and the underside are each essentially in one plane of a cross-section to be insulated in an application state.
  • the upper side or the lower side can also have a step-like character, which means that the upper side or the lower side does not have to be completely flat.
  • the insulating elements are provided in a stack when they are provided, with all the insulating elements stacked on top of one another being aligned essentially in the same way in space.
  • Providing the insulating elements in the form of stacks has the particular advantage that a position of the fixing elements is predefined as a result. The robot can thus pick up insulating elements in a predefined manner without having to ensure correct alignment of the insulating elements through additional work steps.
  • Such insulating elements can already be stacked on top of one another for transport, so that they are packaged and transported in the stacked state. On the one hand, this brings savings in transport costs, because the insulating elements can be packed in a more space-saving manner, so that more insulating elements can be transported in a certain volume than was the case with conventional insulating elements.
  • stacking such insulating elements offers the advantage that mix-ups of different insulating elements can be recognized more easily. If, for example, a first insulating element is packed in a container with a plurality of second insulating elements, this is immediately noticeable because the first insulating element cannot usually be stacked with the second insulating element. This can greatly reduce confusion.
  • the individual insulating elements can be damaged less easily due to the stacked arrangement for transport and storage. If, as before, the individual insulating elements are transported loosely in a container, there is a great deal of contact between the insulating elements, and damage can occur from time to time. However, if the insulating elements are transported in stacks, the number of mechanical contacts between the insulating elements is greatly reduced.
  • the insulation elements can be designed in such a way that the intended contact points are robust or less susceptible to damage, and/or that areas of the insulation elements that are easier to damage are arranged in protected areas which, for example, are covered by the adjacent insulation elements when stacked.
  • the entire system can be loaded and prepared so that it can work autonomously for longer periods of time. Since, as a rule, many such insulating elements are installed in each motor vehicle, this means a large saving in terms of human labor.
  • Stacking also offers the particular advantage that automation can be configured much more efficiently and cost-effectively.
  • the robot can be designed to be less complex than when a robot has to grip insulation elements in a disordered state. By providing them in stacks, the gripping process of the insulating elements by the robot can be simplified and made more efficient.
  • the insulating element has an upper side and a lower side which, in a state of use, are essentially aligned in a plane of a cross-section of the structural element to be insulated.
  • the insulating element has at least one or at least two or at least three contact points on the upper side and on the underside, these contact points being designed in such a way that when several identical insulating elements are stacked, adjacent insulating elements rest on one another via these contact points and are thereby arranged parallel to one another.
  • the insulating element has at least one or more contact points on the upper side and on the underside, which rest on one another when adjacent insulating elements are stacked.
  • the insulating element has a stack height which corresponds to an additional height in the stacking direction of a stack of insulating elements, by which the stack grows when another insulating element is stacked on top of the stack.

  • a stack comprises at least ten or at least fifteen or at least twenty or at least twenty-five or at least thirty stacked insulating elements.
  • a stack comprises at most 150 or at most 120 or at most 100 or at most 80 or at most 60 stacked insulating elements.
  • a bottom insulation element of the stack rests on a base element.
  • the basic element is designed in such a way that the stack is arranged on it in such a way that the stacking direction runs essentially vertically.
  • the base element is designed in relief, with a correspondingly shaped depression being formed on a surface of the base element for each stack.
  • a flat base plate can be provided on which various support elements such as columns, elevations or the like are provided, which position, align and support the stack at a predefined location.

  • a first formation is designed to accommodate a stack of a first insulating element type, and at least one further formation on the same base element is designed to accommodate a stack of the same insulating element type.

  • the method includes the further step: interrupting the automated process if three or more insulating elements out of ten insulating elements that have been attached one after the other are each detached from the structural element during testing.
  • the robot applies a force of at least 70 N, preferably at least 80 N, preferably at least 90 N, particularly preferably at least 100 N, when attaching the fixing element.

  • the fixing elements can be designed to be more robust overall, so that damage to the fixing elements during production and transport of the insulating elements can be largely avoided.
  • the method comprises the further step: coating the structural element after the insulating element is attached to the structural element and before the expandable material expands.
  • the method includes the further step: expanding the expandable material, the expanded material permanently attaching the insulating element in the structural element, so that the fixing element is only used for temporary pre-fixing of the insulating element in the structural element.
