  • Patent number: 7913380
    Abstract: A wafer table for providing electrical components of a wafer includes a rotary disk to receive a wafer. The rotary disk is configured to be displaced parallel to a wafer plane in discrete steps such that the components arrive at a stationary pick-up position. A stationary auxiliary facility is assigned to the pick-up position, and a first rotary drive rotates the rotary disk. A carriage supports the rotary disk and is displaced in a stationary linear guide parallel to the wafer by means of a linear drive. The first rotary drive and the linear drive are positioned such that each of the components arrives at the pick-up position.

  • Patent number: 6883228
    Abstract: A turret-like insertion head having at least one twisting device for mounting electrical components. The insertion head has a stator, a rotor and an optical measuring device. A plurality of circularly distributed grippers are mounted on the rotor such that the grippers can rotate about a mounting axis. The optical measuring device detects the position of the components held on the grippers, and as a result, a component can be twisted into its approximate mounting position during forward movement of the gripper before making a final position measurement, thereby saving time.

  • Publication number: 20040148767
    Abstract: An assembly system and a method are for assembling components on substrates. The system includes a transport track and several substrate carriers that can be displaced, for example, perpendicularly to the transport track. The substrate carriers can be loaded with substrates using loading that can be displaced in the direction of transport. Manipulation devices for removing components from feed devices and depositing the components on the substrates are arranged next to the transport track, so that they can be displaced laterally in the direction of transport. The feed devices can be displaced in a substantially perpendicular manner in relation to the direction of transport, in order to align the pick-up point for the respective components along a single pick-up track, parallel to the transport track.

  • Publication number: 20040143963
    Abstract: The invention relates to an assembly system and method for assembling components on substrates, with, for example, two substrate support pairs arranged perpendicular to a conveyor run, comprising substrate supports (110, 130, 120, 140) which may be displaced perpendicular to the conveyor run. Assembly fields (500, 550) are arranged to the side of the conveyor run, which can be supplied with circuit boards (L) by means of the substrate supports (110, 130, 120, 140). A loading device (210) and an unloading device (220) are arranged along the conveyor run (T), by means of which the circuit boards (L) can be placed on the substrate supports (110, 130, 120, 140). The loading device (210) and the unloading device (22) may be displaced along the conveyor run in a loading direction and an unloading direction. A flexible execution of assembly processes is possible with the above arrangement.

  • Publication number: 20030226251
    Abstract: A fitting system and a method of fitting substrates with components includes, along a conveyor line, loading apparatuses provided in a conveying direction. Each of the loading apparatuses include at least two holding regions arranged one above another, so that substrates delivered along the conveyor line can be transferred to the upper holding region or the lower holding region. In this case, it is possible to feed substrates to fitting areas and at the same time to move substrates past the fitting areas. This achieves a very high performance per unit area of the fitting system. Furthermore, great flexibility is possible in the selected processing of the substrates.

  • Patent number: 6575688
    Abstract: Placement head and placement system for a placement apparatus for placing components in a placement plane, at least one placement head being provided with at least one gripper for picking up and/or putting down the components. The gripper is fitted in an edge region of the placement head, with the result that, in the case of a projection of the placement head onto the placement plane, the image of the gripper situated in the placement position essentially does not project from the image of the placement head. According to the invention, simultaneous independent placement using a plurality of placement heads is possible without the risk of a collision of the placement heads.

  • Patent number: 6428907
    Abstract: Positioning arms for positioning and assembling systems are subjected to high accelerations and must therefore be made lightweight but nevertheless resistant to bending and twisting. The use of composite materials based on metal or ceramic foams and non-expanded materials for positioning arms in positioning and assembling systems allows these positioning arms to be lightweight and nevertheless to have high rigidity. Semifinished products are arranged in the non-expanded material, since a better connection between the semifinished product and material is ensured there than in the metal or ceramic foam.

  • Patent number: 5994799
    Abstract: A linear guide is fastened onto a chassis of a positioner and an elongated bearer for positioning a head is guided at one end on the linear guide and extends transversely thereto. When the bearer is braked, inertial forces arise which cause elastic excursions of the bearer and set it into oscillation. A drive for the bearer is allocated to the end of the bearer opposite the linear guide. The drive is a linear motor containing an iron or core and produces a restoring torque when there is an angular deviation of the secondary part attached to the bearer, which results in reduction of oscillations of the bearer and more rapid achievement of the processing position.
