Problems solved by technology

This can lead to the fact that, at the start of further processing, the end point of the material strip can be further processed without any problems, but the starting point of the material strip is already hardened and cannot be further processed, e.g. for connection to another body part

Embodiment Construction

[0012] The figure shows schematically in graph form how a two-component adhesive consisting of a base component and a base hardener is applied in an application station 10 in the form of an adhesive strip 12 to a workpiece, which At a later point in time another workpiece is joined in the joining station 14 . The sequence of working steps is schematically shown by a time axis 16 whose zero point 18 coincides with the point in time at which the workpiece is introduced into the application station 10 . The adhesive application process 20 starts at an application start time 22 and ends at an application end time 24 . In the drawing, the adhesive strip 12 is shown schematically at an application point in time 26 between the application start time point 22 and the application end point in time 24 . At a transfer point in time 28 , the workpiece is transferred from the application station 10 to the joining station 14 . At a further processing start point in time 30 after the trans...

Abstract

The invention relates to a method for applying an at least two-component, curable and viscous material in the form of a material strand (12) or a series of material points to a workpiece, an application process (20) starting at an application start time (22) and ending at an application end time (24), and the workpiece with the material applied thereon being destined for further processing (32) which starts at a processing start time (30) and ends at a processing end time (34). According to the invention, the mixing ratio (38) of the components is varied by a control device depending on predetermined and / or measured parameters (22, 24, 30, 34) during the application process (20) in such a way that the material applied to the workpiece can be processed at any point of the material strand (12) or at any material point at the processing starting time (30).

Description

technical field [0001] The invention relates to a method for applying an at least two-component, curable and viscous material to a workpiece in the form of a material strip or a row of material dots, wherein the coating process start at the start time point and end at the coating end time point, and wherein the workpiece with the coated material is provided for a further processing process which starts at the further processing start time point and is processed further The end time point ends. Background technique [0002] In known methods of this type, for example, a two-component or multi-component adhesive is applied to a motor vehicle body part and the body part is joined to another body part after the coating process or after a certain period of time , in that the other body part is pressed against the material strip or row of material points and the material then hardens. In the case of large workpieces, to which long strips of material are applied and in which the c...
