Embodiment Construction

[0082] figure 1 The welding nozzle 3 of the welding device 1 shown in longitudinal section has a tubular cross-section. Inside the soldering nozzle 3 is liquid solder which is conveyed through the soldering nozzle 3 by other components of the soldering device (not shown) and exits at its upper end through the port 6 . This forms a solder wave 5 of liquid solder, into which the components or connections to be soldered can be dipped in order to wet them and soldered in this way.

[0083] A device for cleaning the welding nozzle (hereinafter referred to as cleaning device 2 ) is or can be provided at the upper end of the welding nozzle 3 . The cleaning device 2 has a cover-shaped element 7 adapted to the shape of the welding nozzle 3 and thus also has a tubular cross-section, wherein its inner diameter is slightly larger than the outer diameter of the welding nozzle 3 .

[0084] The ultrasound source 4 is located in the central area of ​​the cover element 7 .

Abstract

The invention relates to a method and a device (2) for cleaning a welding nozzle (3) together with a welding device (1). To facilitate thorough and easy cleaning, impurities on the welding nozzle (3) are removed by ultrasound from an ultrasound source.

Description

technical field [0001] The invention relates to a method for cleaning a welding nozzle according to the preamble of claim 1 , an apparatus for cleaning a welding nozzle according to the preamble of claim 8 , and a welding device according to claim 15 . Background technique [0002] Already known from the prior art are examples of soldering devices that can be used for fixing electronic components to printed circuit boards. The basic structure of such a welding device is known, for example, from DE8408427U1. The soldering device described here has a container in which liquid solder is kept. Disposed inside the container is a solder pressure chamber on which the upwardly pointing nozzle is mounted. In use according to instructions, liquid solder is pumped into the solder pressure chamber by the pump. Due to the overpressure and through-flow occurring there, the liquid solder flows through the nozzle and emerges at its upper end. The emerging solder then flows over the outs...
