Embodiment Construction

[0025] In the text below and in the figures, the same reference symbols are used in each case for identical and mutually corresponding features.

[0026] figure 1 A vacuum clamping device 10 is shown as an example, which is arranged on a table 12 of a processing device, not shown in detail. The vacuum clamping device 10 comprises a housing 14 with a vacuum supply system (not shown in detail), such as a vacuum chamber, arranged in the housing 14 . The housing 14 has an upper side which forms the suction surface 16 of the vacuum clamping device 10 , which is designed as a clamping surface in the example not shown. Adsorption surface 16 has suction port 28 (for example, see figure 2 , 3 ), through the suction port by means of a vacuum supply system, air can be sucked in, and thus the workpiece can be sucked onto the suction surface 16 .

[0027] The suction surface has a plurality of protruding regions 18 which provide contact regions 20 which, during operation of the device...

Abstract

The invention relates to a vacuum clamping device or clamping device having an adsorption surface to which a workpiece to be held can be adsorbed, wherein the adsorption surface has at least one abutment area where the workpiece is held against the work piece. In order to absorb and hold the workpiece in a positionally stable, protective and slip-proof manner, the contact area includes an elastomer coating.

Description

technical field [0001] The present invention relates to a vacuum clamping device or clamping device. Background technique [0002] Clamping or clamping devices of this type are used in particular to hold or lift flat objects during processing, for example holding or lifting flat materials which are stable in position, such as plates, flat plastic parts or plates. [0003] Special requirements are placed when processing workpieces with very smooth and / or delicate surfaces, such as viewing windows or dust covers for displays. In this case, slippage should be avoided during suction and subsequent processing of the held workpiece, and damage should be avoided during the suction process. [0004] It is basically known to arrange a foam lining on the suction surface. A corresponding device is described, for example, in DE 10 2006 050 970 A1. In particular, such foam facings serve to avoid damage to the workpiece to be sucked, in particular to suppress hard impacts on the suctio...
