Abstract

Claims (14)

1 . Method for manufacturing an energy storage of an electrolytic capacitor, comprising the following steps:

a) placing a first component ( 1 , 2 , 3 ) of an energy storage of an electrolytic capacitor ( 13 ) onto a transfer area ( 5 );

b) optical measuring the first component ( 1 , 2 , 3 ) to determine its actual position;

c) determine a deviation between the actual position and a desired position;

d) gripping the first component ( 1 , 2 , 3 ) with a gripper ( 7 );

e) adjusting the actual position of the first component ( 1 , 2 , 3 ) if a deviation between the actual position and the desired position has been determined;

f) placing the first component ( 1 , 2 , 3 ) onto a self-adhesive film at a stacking area ( 8 );

g) repeating steps a) to e) with a further component ( 1 , 2 , 3 ) of an energy storage, of an electrolytic capacitor ( 13 ) and placing the further component ( 1 , 2 , 3 ) onto the first component ( 1 , 2 , 3 ) to form a stack;

h) fixing the further component ( 1 , 2 , 3 ) on the stack;

i) repeating steps a) to e) with a further component ( 1 , 2 , 3 ) of an energy storage of an electrolytic capacitor ( 13 ) and placing the further component ( 1 , 2 , 3 ) onto a topmost component ( 1 , 2 , 3 ) of the stack to enlarge the stack;

j) fixing the further component ( 1 , 2 , 3 ) on the stack;

k) repeating steps i) and j) a plurality of times yielding a completed stack;

l) fixing the completed stack after the last further component ( 1 , 2 , 3 ) has been placed on the completed stack by wrapping the self-adhesive film around at least a section of the completed stack.

2 . Method according to claim 1 , characterized in that steps a) to l) are automated executed.
