Abstract: A mounting apparatus for bonding objects to each other, comprising a cleaning part (3) for cleaning at least the bonding surfaces of first objects (2a, 2b) and a bonding part (4) for bonding the cleaned first objects (2a, 2b) to a second object (2c), wherein both parts are connected to each other so that the objects can be conveyed between both parts, and an inverting mechanism (17) for turning over the first objects (2a, 2b) without touching the cleaned bonding surfaces is provided in the bonding part, whereby the cleaning of the bonding surfaces can be carried out efficiently, and a total time for a series of operations ranging from the cleaning to the completion of bonding can be shortened remarkably.
