Automobile Window Centering Table with Pin and V-Actuator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing centering tables struggle to achieve precise positioning of windows with strongly curved contours, leading to inadequate mounting precision when the upper edge rests on rollers and a third roller, resulting in potential offset presentation to the vehicle opening.
Innovation Solution
A method involving a centering pin glued to a reference point on the window, utilizing a longitudinally movable V-actuator with a compression spring to ensure precise longitudinal and transverse centering, followed by engagement with fixed rollers, ensuring accurate positioning before robot gripping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the upper edge of the window rests on rollers and a third roller is used for positioning, then the window can be positioned on the centering table, but the positioning precision is insufficient for windows with strongly curved contours
Solution Approach 1:
A pin is introduced as an intermediary element that is glued to a reference point on the window. This pin engages with the V-shaped actuator to provide precise positioning control, mediating between the window and the positioning mechanism while accounting for curved contours
Solution Approach 2:
The positioning mechanism uses a V-shaped actuator that can change its geometry and position parameters longitudinally. The V-shape allows the pin to be engaged at different positions and angles, enabling precise positioning adaptation for windows with varying curvature parameters
2Manufacturing precision
If a pin is glued to a reference point on the window and engaged with a V-actuator, then precise longitudinal and transverse centering is achieved, but the device complexity increases
Solution Approach 1:
The V-shaped actuator combines multiple positioning functions into a single mechanism. It simultaneously provides longitudinal positioning through its movement and transverse centering through its V-shape geometry, merging what would otherwise require separate positioning systems
Solution Approach 2:
The V-actuator serves multiple functions: it positions the pin longitudinally, provides transverse centering through its V-shape, and can engage with the pin at various positions. This multi-functional element reduces the need for multiple separate positioning mechanisms

AI summary
The method involves adhering a pin (23) in a reference point of a glass (2) before arranging the glass on studs (3, 4, 6, 7) of a centering table (1). The glass is displaced for supporting a transversal upper edge (11) against two fixed rollers (12, 13), which are spaced with respect to each other, where the displacement is obtained by controlling an actuator equipping the table and provided with a longitudinally movable V block (24) for snapping the pin with the block to longitudinally center the glass supported on the rollers and transversely by an engagement of the pin in base of the block. An independent claim is also included for a centering table comprising two fixed rollers.
