Problems solved by technology
In addition to requiring a high energy expenditure, the heating of the pipes also requires such devices to have a relatively complex construction
Furthermore, there is a risk of possible thermal degradation of the polymer when using heated conveying pipes if the polymer remains in the heated conveying pipe for a longer period of time, for example due to temporary production stoppages or shift changes
This altered binder material cannot be reused, which may lead to an increase in waste material
If hardening of the adhesive material occurs in the delivery tube, the delivery tube is no longer usable and has to be replaced, which is costly

Embodiment Construction
[0022] figure 1 A device 100 is shown for joining components 200 by connecting said components to each other by adhesive bonding.
[0023] The device 100 has a coating unit 10 and a crosslinking device 11 placed after said coating unit 10 , so that the adhesive material 12 for joining is processed in two steps. The adhesive material 12 is a two-step set adhesive material 12 .
[0024] The adhesive material 12 has a solid state in the initial state and is present in the form of a strip-shaped profile. In this state the adhesive material 12 is wound on the roller 13 of the application unit 10 from which it is unwound during the process or method.
[0025] The adhesive material 12 unwound from the roller 13 is fed continuously as a strip-shaped profile to the heating unit 14 of the application unit 10 . The heating unit 14 is arranged at the end of the application unit 10 so that after heating the adhesive material 12 the adhesive material can be applied directly on the compon...

Abstract
The invention relates to a method for joining components (200), in which an adhesive material (12) in the form of a strip profile is applied to the component (200) by means of an application unit (10), wherein , the adhesive material (12) designed in the form of a strip profile is melted in the heating unit (14) of the coating unit (10) and applied in the molten state to the component (200), and wherein the applied The adhesive material (12) on the component (200) is converted into a crosslinked state by energy input in the crosslinking device (11) arranged after the coating unit (10).
Description
technical field [0001] The invention relates to a method for joining components. Furthermore, the invention relates to a device for joining components. Background technique [0002] Methods for joining components are known, for example, from patent documents EP 312 496 B1 and EP 3 098 276 A1. Adhesive materials in a viscous state are used here to join components, for example vehicle components. In the application unit for applying the adhesive material on the component, the viscous adhesive material is usually conveyed through the delivery pipe, since the adhesive material has a very high viscosity at room temperature and in this state cannot be conveyed through the pipe, so the conveying pipe must be designed to be heated. In addition to requiring a high energy expenditure, the heating of the pipes also requires such devices to have a relatively complex construction. Furthermore, there is a risk of possible thermal degradation of the polymer when using heated conveying ...
