Drive Screw Transfer Station for Automated Tool Refill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual process of changing drive screws in joining tools is time-consuming and poses safety risks, especially in automated settings where quick and precise screw changes are necessary.
Innovation Solution
A transfer station is designed to automate the process of changing drive screws, featuring a housing with a sleeve holder that can move between attachment, filling, and release positions, and a magazine to store multiple drive screws, allowing for easy and quick replacement of worn or mismatched drive screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual drive screw changing is used, then the process is simple, but it is time-consuming and poses safety risks
Solution Approach 1:
The system performs drive screw changing automatically without human intervention. The robot manipulator autonomously removes worn drive screws and installs new ones using the transfer station, eliminating the need for manual operation while significantly reducing changing time and safety risks
Solution Approach 2:
A transfer station acts as an intermediary device between the robot manipulator and the joining tool. It stores multiple drive screws and facilitates automated transfer to the joining tool, enabling systematic automation of the drive screw changing process
2Device complexity
If manual drive screw changing is used, then equipment complexity is low, but productivity decreases
Solution Approach 1:
Multiple drive screws are pre-loaded into the transfer station's magazine before the joining operation begins. When a drive screw needs replacement, the system can immediately transfer a new one without waiting for manual intervention, maintaining operational continuity and productivity
Solution Approach 2:
The automated system performs drive screw replacement independently, allowing the joining tool to remain productive without interruption. The robot manipulator and transfer station work together to ensure continuous operation
3Reliability
If automated drive screw changing is implemented, then safety improves, but device complexity increases
Solution Approach 1:
The transfer station serves as a dedicated intermediary device that handles all interactions between the robot manipulator and the joining tool during drive screw changing. This specialized intermediary enables automated operation and improved safety while containing the complexity increase to a specific, manageable component

AI summary
A transfer station for storing a plurality of drive screws. One drive screw can be taken out of the transfer station by a joining tool comprising a sleeve adapted to receive the drive screw to then carry out at least one joining operation. The transfer station having a housing longitudinally extending in height along a vertical axis X, in width along a horizontal axis Y and in depth along a depth axis Z; a sleeve holder movably connected to the housing and operable to hold and release the sleeve of the joining tool; and a magazine adapted to store the plurality of drive screws. The sleeve holder is movable between an attachment position, a filling position and a release position.
