  The object of the present invention is to provide a sheet-like object with little shape rigidity, which consists of an electrode material and / or a separator material in the context of technical teachings for handling sheet-like objects, in particular in the manufacture of electrochemical energy stores. The technical teaching which also provides the advantages when dealing with.

  This problem is solved by a method for mounting a sheet-like object or a structure for carrying out this method according to one of the independent claims.

  In accordance with the present invention, a method for placing sheet-like objects, wherein a plurality of such objects are placed one on top of the other, and individual or plurality of objects are intermittently viewed from above. A way to be removed again is intended. Moreover, what is intended here is that the objects are placed on top of each other, either shifted from each other or rotated relative to each other, or shifted and rotated relative to each other.

  In this context, a sheet-like object is a planar object, preferably a thin planar object, i.e. preferably the smallest dimension whose dimension in the direction perpendicular to the surface is completely inside the surface. It can be understood as a planar object that is much smaller than the dimension of the section. Examples of sheet-like objects are in particular electrochemical materials such as are used during the manufacture of electrochemical energy stores, such as electrode materials or separator materials.

  Such a plurality of objects may be understood in this connection as a number of objects greater than one.

  The term “stacked” of such objects can be understood in this context as creating or maintaining the structures of these objects that contact each other on their surfaces. The surface of the object is then preferably substantially perpendicular to the direction of gravity. If the objects are moved or shifted relative to each other in the direction of the tangent to the surface and placed one on top of the other, for purposes of the description of the invention of this application, the objects are placed one on top of the other with the centers shifted from one another. It is burned. If the objects are rotated and placed on top of each other about an axis perpendicular to the plane, the objects are rotated and placed on top of each other. The process of shifting, moving or rotating may be arbitrarily combined when placing sheet-like objects stacked on top of each other.

  Preferably, according to the invention, it is intended to remove at least one object by lifting it. The object can then be lifted in various ways, preferably by mechanically gripping the object to be lifted, by using an electrostatic lift device, or particularly preferably. This may be done using a low pressure lifter. Such a lifting device is also preferably used for mounting one object on another object, in particular centered or rotated relative to each other, or centered and rotated relative to each other. It's okay.

  In this context, a low-pressure lifter causes the sheet-like object to use low pressure by acting on the opposing surfaces of the sheet and pressing the sheet against one or more low-pressure chambers of the low-pressure lifter. It can be understood as a lifting device that is suitable for lifting these sheet-like objects by at least local suction. Lifted seats can also be easily placed by turning on and off the low pressure or by turning on the overpressure or both.

Alternatively, it is intended to be fixed by being exerted on a part of this object. Preferably, then, at least one point or at least part of the object is at the edge of the surface of the object. In particular, this embodiment of the present invention is particularly useful when a sheet-like object has little shape rigidity, as is often the case with electrode materials or separator materials for constructing electrochemical energy stores. It has been found that it is particularly advantageous when the shape rigidity is slightly lower than that of the object.

  Particularly preferably, the object used is an object that is at least partially breathable. Especially if the sheet-like objects are lightly attached to each other, or at least partly breathable, depending on the nature of the material and the resulting adhesion or cohesiveness, multiple sheets with a low-pressure lifter Can be sucked together according to the present invention, the center is shifted or rotated, or the center is shifted and rotated to place a sheet-like object, which is particularly effective and reliable.

Can be prevented. At the same time, it prevents further sheet-like objects below it from being lifted as well.

  In order to hold down the sheet-like object, in particular the sheet-like object 4, for example, points 15 a, 15 b, 15 c, 15 d can be envisaged, for example using a mechanical press.

  FIG. 2 shows a similar situation with an example of sheet-like objects that are rotated and placed on each other. Here, for example, points 16a, 16b, 16c and 16d are conceivable in order to hold down the sheet-like object below.

  FIG. 4 shows a preferred embodiment of the structure according to the invention, in which a lifting device 1, preferably a suction lifter having a suction cup 6 or a low-pressure chamber 6, is attached to the lifting device 2. The lifting device 1 can be lifted and / or lowered in the vertical direction 8 using the lifting device 2.

Particularly preferably, the object used is an object that is at least partially breathable. In particular, if the sheet-like objects are lightly attached to each other, or at least partly breathable, depending on the nature of the material and the associated adhesion or cohesiveness, a plurality of low pressure lifters 1 are used. If the sheets are sucked together, it is particularly effective by placing the sheet-like object shifted and / or rotated as shown in FIG. 1, FIG. 2 or FIG. These sheet-like objects can be pulled apart reliably and easily.

  FIG. 5 shows a further preferred embodiment of the structure according to the invention, in which the presser 3 is attached to the lift device 1 so as to move together with the lift device 1. Thus, when the lift device 1 is rotated about the vertical axis 9 or when the lift device 1 is moved parallel to the horizontal plane 10, the one or more pressers 3 preferably move together to lift A plurality of objects 4 underneath the object 5 or one object 4 under the object 5 to be lifted is always preferably the point 14a shown in FIGS. 1, 2 and / or 3 , 14b, 14c, 14d, 15a, 15b, 15c, 15d, 16a, 16b, 16c and / or 16d.

These rotation points or connecting portions 11 are preferably configured such that one or more pressers 3 can be moved also in the vertical direction 13, preferably independently of the lifting device 1.

  It is preferably intended that a lifting device 1 that can be rotated about a vertical axis 9 and / or movable in a horizontal plane 10 is used for removing and / or placing objects. The lift device 1 is placed and / or positioned using a device 7 that recognizes the position of the object 5 to be removed using information technology methods. A preferred lifting device is a mechanical gripping device, an electrostatic lifting device or a low pressure lifter. At this time, the device 7 for recognizing the position of the object 5 to be removed is preferably removed by using an information technology method, preferably by a signal processing method, particularly preferably by using a pattern recognition method.

  FIG. 6 shows a further preferred embodiment of the structure according to the invention, in which an information technology device 7 which can be used to recognize the position of the sheet-like object 5 is preferably a lift device. The lift device 1 can be arranged according to the position recognized as a result. These information technology devices 7 are preferably provided with one or a plurality of cameras, which preferably take images of the edge of the sheet-like object, and from these images, use information technology methods. It is possible to detect the position of a plurality of sheet-like objects or one sheet-like object. In this case, a pattern recognition method is preferably used, particularly preferably an edge detection method.

  Edge detection is part of segmentation in image processing and attempts are made to separate the planar regions of a digital image from each other. Many methods for automatic segmentation are known. In principle, these methods are often divided into pixel-oriented, edge-oriented, and region-oriented methods. Further, a distinction is made between a model-based method starting from a specific shape of the object and a texture-based method that takes into account the homogeneous structure inside the object.

  Method boundaries are often fluid. Various methods may be combined to obtain better results.

  A so-called edge operator is to recognize a transition between these areas when detecting an edge. These transitions are marked as edges. On the other hand, however, individual regions will also be recognized as such, and a good edge detector will not divide into two parts by edges. The edge detector calculates the corresponding edge image from which one can see all the edges. In order to achieve this, each image point is newly set by calculation with a matrix.

  Edge-oriented methods for segmenting digital images look for edges or object transitions in the image. Many algorithms still do not provide closed edge features. These must first be combined with further methods to include the object. However, this is often not necessary in order to locate a sheet-like object of known shape. Edges are often between pixel regions of an image. The result of the algorithm may be a polygon (or line), but some operations result in an edge even as another color pixel.

  Pixels belonging to one edge can be found by methods such as Sobel operator and Laplace operator, and also by gradient search. But these are still loose and must be perfected by edge tracking algorithms. General methods for generating well-organized object contours or at least edge features from edge pixels are described in the authors E.E. Mortensen, W.M. A. Barrett, J.M. K. It is Udupa's live wire method. This idea can be compared with a navigation system that detects the optimum route from the start point to the destination. Optimally, what is meant in the context of segmentation is that the path between the start and the destination always goes through the darkest edge pixel. Optimal route selection is a standard problem in information processing, and can be solved by horizontal search, for example.

  A very well known method is also watershed deformation that works with grayscale images and always results in closed edge features. Further methods are parallel and sequential edge extraction, optimal edge search, Felzenszwalb-Huttenlocher algorithm, active shape model, and snakes.

  In the embodiment of the invention shown in FIGS. 4, 5 and 6, preferably at least one lifting device 1, particularly preferably rotatable about a vertical axis 9 and / or movable in a horizontal plane 10.
