  • Patent number: 11345046
    Abstract: A gripping unit for the automated assembly of a component having at least one holding region may include at least one assembly gripper configured to grip the component in the at least one holding region. The at least one assembly gripper may include two gripping fingers that may be axially adjustable towards one another into a gripping position where the component is securable between the two gripping fingers, and that may be axially adjustable away from one another into a released position where the component is releasable from the two gripping fingers. The two gripping fingers may include a first gripping finger having a first gripping contour and a second gripping finger having a second gripping contour. The first gripping contour and the second gripping contour may be structured complimentary to the at least one holding region of the component.

  • Patent number: 10094623
    Abstract: Arrangement comprising a sealing element and a heat exchanger, in an air channel, wherein the heat exchanger has a plurality of pipes which carry a first fluid and are defined in their end regions by collection vessels and can have a second fluid flowing around them. The arrangement is characterized in that the air channel has a first guide groove on an inner surface, which guide groove is formed by a first web and a second web, and a second guide groove which is formed by a third web and a fourth web, the third web and the fourth web being disposed between the first web and the second web and the sealing element enveloping the heat exchanger along the collecting vessels and its short sides.
