Cable Gripper Swing Mechanism for Fast Connector Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device assembly apparatuses face challenges in accurately and efficiently correcting the precise position of flexible cables during connection work due to unpredictable deformation and alignment issues, leading to prolonged connection times and potential collisions with connectors.
Innovation Solution
An electronic device assembly apparatus featuring a gripping device that is swingable in an arc shape or movable in the width direction of the cable, equipped with suction devices and gripping claws, which passively corrects the cable's position by tracing the connector's edge and applying force components to ensure accurate insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If feedback control is used to correct cable position after contact with connector, then alignment precision is improved, but connection time increases
Solution Approach 1:
The gripping device is pre-configured with swing capability and force application mechanisms before the cable insertion process begins. The device can proactively adjust cable position through controlled swinging motion and force application, eliminating the need for reactive feedback control after connector contact, thus reducing connection time while maintaining alignment precision
Solution Approach 2:
The invention enables the system to skip the time-consuming feedback control loop by using the gripping device's inherent swing mechanism to rapidly correct cable position deviations during the insertion process, allowing the cable to be inserted into the connector without repeated position corrections
2Adaptability or versatility
If the holding device is separated from the robot arm joint, then robot arm flexibility is improved, but position correction accuracy decreases
Solution Approach 1:
The gripping device acts as an intermediary between the robot arm and the cable. It incorporates a swing mechanism that serves as a mediator to transmit and amplify position correction forces, compensating for the separation from the robot arm joint while maintaining position correction accuracy through mechanical leverage and controlled swinging motion
