Fastener Welding Suspension Frame for Precise Part Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener welding technologies face difficulties in properly welding fasteners to parts that are not perfectly positioned, as movable platforms often struggle with movement and re-centering mechanisms, limiting versatility and speed in assembly operations.
Innovation Solution
A fastener welding apparatus comprising a frame assembly, welding assembly, coupling assembly, and locating assembly, where the suspension frame is pivotably coupled to both the frame axle and welding axle, allowing selective movement within a predetermined range, and an actuator facilitates relative movement between mating structures to adjust the welding assembly for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a movable platform is used to allow welding assembly adjustment within a range, then adaptability to part position variations is improved, but movement reliability and stability deteriorate due to forces exerted by welders and platform weight
Solution Approach 1:
The welding assembly is mounted on a movable platform that can dynamically adjust its position within a predetermined range in response to part position variations. The platform moves from a first position to a second position based on the detected location of the part, enabling adaptability while maintaining stability through controlled movement rather than fixed rigid positioning.
Solution Approach 2:
A sensor detects the actual position of the part and provides feedback to the control system. Based on this feedback, the controller determines the appropriate position for the welding assembly and actuates the platform to move to the correct location, ensuring reliable and accurate positioning despite part variations.
2Productivity
If robotic arms are used to grasp parts in less than exact orientations, then assembly speed and automation are improved, but welding precision deteriorates when parts are not perfectly positioned
Solution Approach 1:
The welding assembly is made dynamically adjustable through a movable platform that can reposition itself based on part location. This allows the system to accommodate parts in less than exact orientations while maintaining welding precision by adjusting the welding assembly position to match the actual part position.
Solution Approach 2:
The sensor detects the actual position and orientation of parts grasped by the robotic arm, and this information is used by the controller to determine the appropriate welding assembly position. This feedback mechanism ensures that welding precision is maintained even when parts are positioned with some variation from the ideal location.
