Vacuum Holding Head Ring Actuation for Rotatable Plate Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum holding devices for plate-shaped workpieces, such as glass plates, face challenges in conveniently operating the required double actuation control, especially when the holding head is rotatably mounted close to the axis of rotation, limiting the ease of motion and increasing operational effort.
Innovation Solution
The configuration of at least three actuating elements in a double actuation circuit, where the first two elements are positioned on opposite sides of the axis and the third element is ring-shaped, surrounding the axis, allows for easy operation at any angular position, with the first two elements releasing a locking mechanism for the third, enabling secure double actuation and additional degrees of freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the holding head is rotatably mounted close to the axis of rotation to enable expansion by further degrees of freedom, then adaptability is improved, but the ease of operation of the double actuation control deteriorates
Solution Approach 1:
The control system is segmented into multiple independent actuating elements (first actuating element, second actuating element, third actuating element) distributed around the axis of rotation. Each element can be operated independently to achieve the double actuation function, making the control system adaptable to different rotational positions while maintaining ease of operation.
Solution Approach 2:
The actuating elements are arranged in a circular pattern around the axis of rotation, transitioning from a linear arrangement to a two-dimensional circular distribution. This allows at least one actuating element to always be accessible from the radial direction, regardless of the holding head's angular position, thereby maintaining ease of operation while enabling rotational mounting close to the axis.
2Device complexity
If the holding head is mounted close to the axis of rotation, then device complexity is reduced, but the accessibility of actuating elements deteriorates
Solution Approach 1:
The actuating elements are arranged in a circular pattern around the axis of rotation, transitioning from a linear arrangement to a two-dimensional circular distribution. This allows at least one actuating element to always be accessible from the radial direction, regardless of the holding head's angular position, thereby maintaining ease of operation while enabling rotational mounting close to the axis.
Solution Approach 2:
The ring-shaped third actuating element serves multiple functions: it acts as a discrete button when viewed from the axial direction and as a rotary dial when viewed from the radial direction. This multi-functionality ensures accessibility and operability from any angular position while simplifying the overall device structure.

AI summary
A holding head is provided for a vacuum holding device for handling a plate-shaped workpiece about an axis. An arrangement of operating elements on a base body of the holding head includes at least three operating elements connected as actuating elements in a double actuation circuit for releasing the plate-shaped workpiece. Two of the actuating elements are arranged on sides of the arrangement opposite to one another with respect to the position of the axis and the third actuating element is designed ring-shaped and surrounds the axis circumferentially.
