Method for depositing sheet-like objects and an assembly for carrying out said method

Abstract

The invention relates to a method for depositing leaf-shaped objects ( 4, 5 ), and to an assembly for carrying out said method, wherein a plurality of such objects are successively placed on top of each other, and wherein, at intervals, single or several objects are removed again from the top. To this end, the objects ( 4, 5 ) are placed on top of each other offset from one another and/or rotated in relation to one another.

         16 . A method for depositing sheet-like objects, particularly for depositing electrodes and/or separators for constructing an electrochemical energy store or parts of such electrodes or separators, the method comprising:
 successively depositing a plurality of the objects atop one another individually or in groups and   intermittently removing individual or multiple objects from above,   wherein the objects are deposited atop each other offset and/or rotated relative one another, and   wherein a lifting device rotatable about a vertical axis and/or displaceable in a horizontal plane is used to remove and/or deposit objects, said lifting device being aligned and/or positioned by means of a device which recognizes the position of an object to be removed by means of information technology.   
     
     
         17 . The method according to  claim 16 , wherein at least one object is removed by being lifted. 
     
     
         18 . The method according to  claim 17 , wherein at least one object is removed and/or placed atop at least one other object by means of at least one vacuum lifter. 
     
     
         19 . The method according to  claim 16 , wherein at least one first object is held while at least one second object lying atop the at least one first object is removed. 
     
     
         20 . The method according to  claim 19 , wherein at least one first object is held while at least one second object lying atop the at least one first object is removed by a pressure being exerted from above onto at least one point or one part of said object. 
     
     
         21 . The method according to  claim 16 , wherein at least one object is at least partially permeable to air. 
     
     
         22 . The method according to  claim 16 , wherein at least one object is an electrode or a separator for constructing an electro-chemical energy store or a part of such an electrode or separator. 
     
     
         23 . An assembly configured to perform a method in accordance with  claim 16 , the assembly comprising:
 at least one lifting device arranged on a lifting apparatus so as to be rotatable about a vertical axis and/or displaceable in a horizontal plane.   
     
     
         24 . The assembly according to  claim 23 , wherein the at least one lifting device comprises a vacuum lifter. 
     
     
         25 . The assembly according to  claim 23 , further comprising:
 at least one hold-down element configured to hold the at least one first object while at least one second object lying above the at least one first object is removed.   
     
     
         26 . The assembly according to  claim 25 , wherein the at least one hold-down element is structurally connected to the lifting device such that said hold-down element does not move, or at best only moves vertically, in the kinematic reference systems of the lifting device when the lifting device moves horizontally relative to a deposited or positioned object. 
     
     
         27 . The assembly according to  claim 23 , wherein the at least one lifting device comprises a plurality of pressure chambers. 
     
     
         28 . The assembly according to  claim 23 , further comprising:
 an IT device configured to recognize the position of an object to be removed.   
     
     
         29 . The assembly according to  claim 28 , wherein the IT device is configured for aligning and/or positioning the lifting device based on the position of an object to be removed recognized by the same or by a further IT device. 
     
     
         30 . The assembly according to  claim 28 , wherein the IT device comprises a camera.
