Method for testing leakage of housing of microswitch during production of element in automated manufacturing systems, involves detecting and evaluating deformation of elastic component of element with respect to leakage of element

摘要

#CMT# #/CMT# The method involves exposing an element i.e. housing (1), to pressure and/or vacuum. Deformation of an elastic component of the element due to the pressure and/or vacuum is detected by a sensor system with optical units e.g. camera and light barrier. The detected deformation is evaluated with respect to leakage of the element. An aperture of the housing is provided with a membrane (3) as the elastic component, where an actuating element (2) projects to the aperture from the housing. The housing is provided with a closable test hole. #CMT#USE : #/CMT# Method for testing leakage of an element i.e. housing, of an electrical switch i.e. microswitch (all claimed), during production of the element in automated manufacturing systems. Can also be used for testing leakage of the element of electrical appliances and an electronic key and control devices for motor cars. #CMT#ADVANTAGE : #/CMT# The deformation of the elastic component of the element due to the pressure and/or vacuum is detected by the sensor system and evaluated with respect to the leakage of the element, thus enabling testing of the leakage of the element in a simple, cost-effective and reliable manner with small technical effort and at very quick process times. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a test bell with an element to be tested for leakage.'(Drawing includes non-English language text)' 1 : Housing 2 : Actuating element 3 : Membrane 4 : Test bell.
