Horizontal Robot Arm Interface Mechanism Wiring Tension Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing horizontal articulated robots face challenges in efficiently managing wiring members, particularly due to excessive slackness and potential contact with other components, caused by the need for longer wiring lengths to accommodate detachment and reattachment of the cover, which can lead to errors in wiring distance and tension.
Innovation Solution
An interface mechanism is introduced within the arm of a horizontal articulated robot, featuring a fixed plate inside the arm that abuts against the cover's inner surface, allowing for adjustment and secure attachment without detaching the cover from the base, thus maintaining minimal wiring length and preventing slackness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is detached from the base component for maintenance or wiring, then accessibility to internal components is improved, but wiring members become excessively long and slack, causing potential contact with other components
Solution Approach 1:
The arm is segmented into a base component and a cover that can be detached. The interface mechanism is further segmented into a fixed member attached to the base component and a movable member attached to the cover. This segmentation allows the cover to be detached for maintenance while the wiring members remain properly tensioned through the interface mechanism, preventing excessive length and slackness.
Solution Approach 2:
The interface mechanism acts as an intermediary between the base component and the cover. It includes a fixed member on the base component and a movable member on the cover that connects to the fixed member. This intermediary structure allows the cover to be detached while maintaining proper wiring tension through the connection between the fixed and movable members, preventing wiring from becoming excessively long.
2Adaptability or versatility
If longer wiring members are used to accommodate cover detachment, then the cover can be removed without damage, but wiring members contact other components causing errors in wiring distance and tension
Solution Approach 1:
The interface mechanism is segmented into a fixed member attached to the base component and a movable member attached to the cover. The movable member includes a connecting portion that connects to the fixed member and a wiring member connection portion. This segmentation ensures that when the cover is detached, the wiring members remain properly positioned through the interface mechanism, preventing contact with other components and maintaining wiring position accuracy.
Solution Approach 2:
The interface mechanism serves as an intermediary that maintains wiring position accuracy during cover detachment. The fixed member on the base component and the movable member on the cover work together to ensure wiring members remain properly tensioned and positioned, preventing errors in wiring distance and tension even when the cover is removed.
3Reliability
If wiring members are kept short to prevent slackness, then tension control is improved, but the cover cannot be detached without causing wiring damage or excessive tension
Solution Approach 1:
The arm is segmented into a base component and a detachable cover. The interface mechanism is segmented into a fixed member on the base component and a movable member on the cover. This segmentation allows the cover to be detached while the wiring members maintain proper tension through the interface mechanism, preventing both excessive slackness and excessive tension during removal.
Solution Approach 2:
The interface mechanism incorporates a movable member that can move relative to the fixed member. The movable member includes a movable portion that can shift position as the cover is detached or reattached. This dynamic adjustment allows the wiring members to maintain proper tension throughout the cover removal and reattachment process, adapting to the changing geometry without becoming too loose or too tight.
4Ease of manufacture
If the fixed member is attached to the outer surface of the cover, then assembly is simplified, but manufacturing tolerances cannot be improved and dust-proofing is compromised
Solution Approach 1:
Instead of attaching the fixed member to the outer surface of the cover as in conventional designs, this invention inverts the approach by attaching the fixed member to the inner surface of the cover. The movable member extends outward to connect with external components. This inversion allows the fixed member to serve as a precise reference surface for the movable member, improving manufacturing precision and enabling better dust-proofing while maintaining assembly simplicity.

AI summary
An interface mechanism is provided in a cover of an arm of a horizontal articulated robot and connects a wiring member inside the arm and a wiring member outside the horizontal articulated robot to each other. The interface mechanism includes a fixed member that is disposed inside the arm and that is fixed to a cover, and also includes a connecting member that is attached to the fixed member and to which the wiring member inside the arm and the wiring member outside the horizontal articulated robot are connected. The fixed member is fixed to an inner surface of the cover in a state where the fixed member abuts against the inner surface from below.
