Vacuum Clamping Nozzle With Dynamic Sealing for Screw Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum clamping nozzles face issues with reduced suction force due to unstable vacuum sources and tolerance of screw members, leading to incorrect positioning or damage during high-speed screwing operations, which can result in locking failure and surface damage.
Innovation Solution
The vacuum clamping nozzle design includes a first and second housing with an accommodating space, gap, and clamping assembly, where the clamping assembly moves relative to the housing upon gas exhaustion, providing additional clamping force through a rotatable member and sealing member, and a movable member with a contact member that pushes against the locking member to enhance suction stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional vacuum clamping nozzle is used, then the structure is simple, but the suction force is reduced due to unstable vacuum source and tolerance of screw member
Solution Approach 1:
The patent introduces a movable clamping assembly that can dynamically adjust its position and clamping force based on the presence and position of the locking member. The clamping assembly moves along the central axis of the nozzle under vacuum pressure, automatically adapting to variations in locking member tolerance and vacuum source stability, thereby maintaining reliable suction force without requiring a complex fixed structure
Solution Approach 2:
The vacuum clamping nozzle is divided into distinct functional segments: the stationary housing, the movable clamping assembly, and the sealing member. This segmentation allows each component to perform its specific function independently - the housing provides structural support, the clamping assembly applies dynamic clamping force, and the sealing member ensures vacuum integrity - resolving the contradiction between structural simplicity and suction reliability
2Productivity
If high-speed screwing operation is performed, then the productivity is improved, but the locking member may move to incorrect position or fall causing damage
Solution Approach 1:
The patent ensures continuous clamping action through the movable clamping assembly that remains engaged with the locking member throughout the entire screwing process. The vacuum force continuously acts on the clamping assembly to maintain contact with the locking member, providing uninterrupted positioning control even during high-speed operations, thus preventing incorrect positioning or dropping
Solution Approach 2:
The system provides automatic feedback control where the position of the locking member influences the position of the clamping assembly. As the locking member is suctioned and positioned, the clamping assembly responds by adjusting its clamping force and position accordingly, creating a self-regulating system that maintains positioning accuracy during high-speed screwing operations

Function Achieved in This Case
This design ensures consistent suction force application, reducing the likelihood of incorrect positioning and damage, by allowing the clamping assembly to move and seal effectively, thereby stabilizing the locking member and preventing surface damage.

AI summary
A vacuum suction nozzle is provided, including a first housing, a second housing, an accommodating space, a gap, and a clamping assembly. The first housing includes a first lateral wall, a first lower surface, a channel, and a through hole. The through hole is formed on the first lateral wall. The second housing is fixedly connected to the first housing, and includes a second lateral wall and a second lower surface. The accommodating space is formed between the first lateral wall and the second lateral wall, and the through hole is opened onto the channel and the accommodating space. The gap is formed between the first lower surface and the second lower surface, and is opened onto the accommodating space. The clamping assembly is disposed in the accommodating space.
