An apparatus for the automated production of glass assemblies includes: a turning machine with at least two spindles, which are rotatable about a common axis of rotation and which each have a workpiece holder, wherein the workpiece holders are arranged opposite one another; one or more gas burners or lasers fixed on a first tool carriage which is movable in parallel and/or perpendicularly to the axis of rotation; one or more drives for driving a rotational movement of the spindles and a movement of the first tool carriage; a pressure module including a pump device at least one working cylinder for applying a pressure to an inner tube and/or to a space between the inner tube and an outer tube; and a control unit configured to control the burners or lasers, one or more drives, the first tool carriage and the pressure module.

Apparatus for the automated production of glass assemblies and corresponding method

The present invention relates to a method for the automated production of a workpiece having at least one diaphragm, including a workpiece for an electrochemical sensor, including providing a workpiece that has a wall with at least one continuous opening through the wall, wherein a diaphragm body is affixed in the at least one opening, such that the diaphragm body completely fills a cross-section of the opening, and processing the diaphragm body by means of a laser.

Method for automated production of a workpiece having a diaphragm

A method for manufacturing a glass assembly comprises the steps: lowering of a dip pipe that gas may flow through vertically to the surface of a glass melt; determining when the surface of the glass melt is encountered by the dip pipe end showing towards the glass melt by detecting an increase of the gas pressure found inside the dip pipe; continued lowering of the dip pipe until a predetermined depth of entry of the dip pipe end showing towards the glass melt is reached; obtaining a predetermined pressure inside the dip pipe while the dip pipe first stays at the given immersion depth for the given duration and after the predetermined duration is completed, is lifted with a given speed vertically to the surface of the glass melt, thus creating a gas bubble in the glass melt whose walls are attached to the end of the dip pipe; continued lifting of the dip pipe vertically to the surface of the glass melt until the gas bubble is separated from the glass melt, with the wall of the gas bubble remaining at the dip pipe end as a closing film; and setting, especially controlling and/or adjusting of the pressure inside the dip pipe based on the geometry of the film closing the end of the dip pipe as determined by an image capturing device.
