Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching sealing profiles to vehicle bodies face challenges in controlling speed fluctuations during the application process, leading to incomplete control over the attachment of sealing profiles.
Innovation Solution
Measuring the relative speed between the sealing profile and the application unit at the point of bonding, using a device with a measuring wheel and encoder to synchronize the application process with the supply of the sealing profile, ensuring optimal control over the attachment speed and length applied.

1Productivity
If the sealing profile is applied using a rolling process with a robot, then the circumferential seal can be completely applied in one continuous operation, but speed fluctuations occur during the application process leading to incomplete control
Solution Approach 1:
A sensor is integrated into the pressure roller to detect the actual application speed in real-time. This feedback signal is transmitted to the control unit, which compares the actual speed with the target speed and adjusts the feed rate of the sealing profile accordingly, ensuring stable speed control throughout the continuous application process
Solution Approach 2:
The pressure roller serves multiple functions: it applies pressure to bond the sealing profile to the vehicle body, drives the sealing profile through the application area, and simultaneously functions as a speed sensor through an integrated measuring device, eliminating the need for separate measurement equipment
2Adaptability or versatility
If the feed rate of the sealing profile is increased or slowed at the point of rolling up, then the glued-on seal can be made to expand or compress, but speed fluctuations lead to problems in applying the sealing profile
Solution Approach 1:
The system dynamically adjusts the feed rate of the sealing profile based on real-time speed measurements during the application process. The control unit modifies the feed speed continuously to achieve desired seal expansion or compression while maintaining application consistency through active feedback control
Solution Approach 2:
The feed rate parameter of the sealing profile is dynamically changed during the application process based on the desired seal geometry. By adjusting this parameter in response to measured application speed, the system achieves both seal expansion/compression and application consistency

AI summary
The invention relates to a method and a device for applying sealing profiles to vehicle bodies or parts thereof, wherein the sealing profile (2) is, in particular, withdrawn from a storage container and, with an adhesive layer (12) arranged on the sealing profile, is rolled up along a line provided for application on the vehicle body or the part thereof by means of a pressure roller (4) of an application unit (5). With previously known methods and devices for rolling up sealing profiles, speed fluctuations during the application process can only be partially controlled. In order to better control such speed fluctuations during the application process, the relative speed between the sealing profile (2) and the application unit (5) is detected at the point of bonding and optimally adjusted to the feeding of the sealing profile.
