Problems solved by technology

Since this type of linear motor connection is also used in assembly technology, where high demands are placed on positioning accuracy, deformation of the linear guide is very undesirable
Although in order to avoid this deformation, the support plate, guide rail bottom and guide mechanism can be designed thicker and heavier, but this will increase the installation space and the mass to be moved, with corresponding disadvantages for automatic assembly equipment

Embodiment Construction

[0031] exist figure 1 and 2 A first preferred embodiment of the device according to the invention is shown in . The linear motor rotor (1) is fixed on the bottom surface of a movable mounting part (2), here a rectangular support plate (2). A support arm or a mounting head is also conceivable as the movable mounting part ( 2 ), for example. The support plate (2) passes through the first type of the first type of balancing member (3) and the first type of the second type of balancing member (4) and the fourth guide member (5) at its corner Or guide dolly (5) connects. The guide trolley (5) is functionally fitted with a parallel track (6) of a linear guide mechanism, so that the figure 2 Move in the direction of movement indicated by the arrow. The track (6) is fixed on a track base (7) which consists of a metal plate. The linear guide mechanism consists of a track (6) and a track base (7). The linear motor rotor (1) is located at a small distance from a linear motor stat...

Abstract

The invention relates to a device, for connection of a linear motor armature (1) to a linear track, comprising a support plate (2), to which the linear motor armature (1) is fixed, at least two guide elements (5), by means of which the support plate (2) may be engaged with the linear track, in order to be displaced in a displacement direction along the linear track. Said device comprises at leastone compensator element (3) of a first type, by means of which the support plate (2) has a sprung, rotating mounting to one of the at least two track elements (5) transverse to the displacement direction and at least one compensator element (4) of a second type, by means of which the support plate (2) has a rotating mounting to another of the at least two track elements (5). By the arrangement oftwo types of compensator elements (3,4), torques and lateral forces on the support plate (2) are not transmitted to the mountings of the linear track and a resonance of the support plate (2) is prevented.

Description

technical field [0001] The invention relates to a device for connecting a linear motor rotor and a linear guide mechanism, especially in an assembly device for assembling components to a substrate. Background technique [0002] Such a device is disclosed, for example, in DE-19842384. The device includes a mobile trolley on which two guide trolleys are directly fixed, and the guide trolleys are supported on corresponding guide rails provided on a fixed guide housing; directly fixed on the mobile trolley. A linear motor stator is arranged in the guide housing, which is opposite the linear motor rotor. [0003] Due to the large magnetic attraction force between the rotor and the stator of the linear motor, and the large heat generated when the linear motor is working, it may cause elongation and bending of the linear motor rotor and the moving carriage. As a result, large forces and moments act on the bearings of the linear guide, which can lead to premature wear of the guid...
