Problems solved by technology

[0011] All of the methods listed for identifying the pipette type have the disadvantage of course that the pipette must be provided with an analyzable marking, code and / or groove in such a way that the pipette type can be unambiguously determined before it is picked up by the assembly head
This step may result in an incidental time cost
It is also disadvantageous, for example, that when using the identification groove, a separate pipette identification unit must be provided on the assembly head

Embodiment Construction

[0023] figure 1 An exemplary flow chart of a method according to the invention for detecting a pipette configuration for an assembly process in an assembly device is schematically shown. Pipettes for assembly of substrates or printed circuit boards are provided in the pipette changer for production. Pipettes with different pipette types are used corresponding to the components to be assembled. The pipette types are distinguished, for example, on the basis of different lengths of the pipettes, different air flows and / or different geometrical features, in particular of the end faces.

[0024] The method according to the invention is carried out prior to assembling the substrate with electronic components. The method according to the invention begins with a start-up step 1 . In a second method step 2, the pipettes arranged in the pipette changer are picked up by the assembly head of the assembly device and mounted on this assembly head.

[0025] In a third method step 3 , the...

Abstract

The present invention provides a method for detecting pipeline configuration in an assembling process. For assembling an electronic component for a substrate, different types of pipettes are provided in a pipette exchanging device. Before substrate assembling, all pipettes are taken out from the exchanging device successively through an assembling head of the assembling device (2). The types of the pipettes which are respectively equipped on the assembling head are determined through an image processing system. Furthermore the determined types of the pipettes which are respectively equipped on the assembling head are transmitted to a control device of the assembling device (4). The pipettes which are just determined respectively are reset to the positions in the exchanging device. Furthermore the information about type of the pipette and the position is stored together. The pipette configuration is known through the information about the type and the position of the pipette is used. Furthermore the control device correctly assembles the pipettes for the assembling head in assembling. Therefore the application of the unsuitable pipette on the component to be assembled is prevented simply and efficiently.

Description

technical field [0001] The invention relates generally to the field of assembling substrates with electronic components by means of assembly devices. In particular, the invention relates to a method for identifying a pipette configuration in a pipette changer for an assembly process in an assembly device. In the pipette changing apparatus, pipettes having different types of pipettes are provided for assembling the substrate with electronic components. Background technique [0002] In assembly technology, especially in so-called surface mount technology (SMT), components are mounted on the surface of a substrate or printed circuit board by so-called assembly devices (eg automatic assembly machines, assembly modules, etc.). The components to be assembled are brought to the pick-up position by means of so-called feeding devices for the assembly process. For picking and placing components, assembly heads are used in assembly devices that can be moved by positioning systems. I...
