Embodiment Construction

[0012] The application device 10 shown in the drawing is used to apply adhesive materials, such as adhesives or sealants, to workpieces, such as body components in motor vehicle construction. The application device is mounted on a robot arm 12 shown schematically in the drawing, by means of which the application device can be moved relative to the workpiece. The application device 10 has an application nozzle 14 which is detachably mounted on a nozzle holder 16 . An application channel 18 for the viscous material extends through the nozzle carrier 16 and the application nozzle 14 to a material outlet 20 at the free end of the application nozzle 14 . The viscous material is introduced into the application channel 18 and conveyed under pressure to the material outlet 20 where it exits and is applied to the respective workpiece.

[0013] In order to fasten the applicator nozzle 14 to the nozzle holder 16 , the nozzle holder 16 has a first connecting part 22 which has a cylindric...

Abstract

The invention relates to a device (10) for applying a viscous material to a workpiece, in particular for applying an adhesive or sealing material to a motor vehicle body component, comprising: an application nozzle (14) with a material outlet opening (20); and a nozzle support (16) that supports the application nozzle (14), on which nozzle support the application nozzle (14) is releasably attached, wherein an application channel (18) extends through the nozzle support (16) and the application nozzle (14) up to the material outlet opening (20). According to the invention, the nozzle support (16) and the application nozzle (14) each have a connection part (22, 24), wherein a first connection part (22) is inserted into a second connection part (24) and is encircled thereby, and the connectionparts (22, 24) can be moved relative to each other in a limited extent from a starting position against the restoring force of an elastic restoring element (38).

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 for applying an adhesive material to a workpiece, in particular an adhesive or a sealant to a motor vehicle body component. Background technique [0002] Such application devices are widely used for applying adhesives and sealants to body components in motor vehicle construction. In this case, the application nozzle with the material outlet is mounted on a nozzle carrier, which in turn is usually mounted on a robot arm. An application channel extends through the nozzle carrier and the application nozzle as far as the material outlet, into which application channel the material to be applied is introduced by means of one or more supply lines. The connection between applicator nozzle and nozzle holder is rigid here. In particular, the connection of the applicator nozzle to the nozzle carrier is then subjected to forces which can lead to increased wear when the applicator nozzle is g...
