Insulated Bracket for Robot Tool Attachment and Umbilical Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial robots face challenges in attaching tools without hollow structures to tool attachment surfaces, as the umbilical member cannot be pulled out due to the closed opening, preventing effective electrical insulation and potential damage from foreign matter like spatter.
Innovation Solution
A bracket with a hollow structure is used, featuring a bracket body with insulation members and an insulating cover, which allows the umbilical member to pass through while maintaining electrical insulation between the tool and the robot body, and preventing foreign matter from entering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tool without hollow structure is directly attached to the tool attachment surface, then the attachment is simple, but the opening cannot be closed off and the umbilical member cannot be pulled out
Solution Approach 1:
A bracket with hollow structure is introduced as an intermediary component between the tool and the tool attachment surface. This bracket provides the necessary hollow passage for the umbilical member to be routed through, while still allowing the tool to be attached to the tool attachment surface. The bracket acts as a mediator that enables both the attachment function and the umbilical member routing function simultaneously.
2Reliability
If insulation members are added between the bracket body and the tool attachment surface, then electrical insulation is improved, but the device complexity increases
Solution Approach 1:
The insulating plate is integrated into the bracket structure by providing through-holes in the bracket body that align with screw holes in the tool attachment surface. The insulating plate is positioned between the bracket body and the tool attachment surface, and the bolts pass through both the insulating plate and the bracket body. This merging approach allows the insulation function to be incorporated into the existing bracket structure without adding separate, independent insulation components.
3Object-affected harmful factors
If the insulating cover is added to cover the gap between the hollow hole and the umbilical member, then protection from foreign matter is improved, but the device complexity increases
Solution Approach 1:
The insulating cover is designed as a flexible component that can be elastically deformed to fit around the umbilical member and seal the gap between the hollow hole and the umbilical member. This flexible shell approach provides effective sealing against foreign matter like spatter, while the elastic deformation capability allows the cover to conform to the specific geometry of the umbilical member and maintain a reliable seal.

AI summary
A bracket that includes a bracket body that is attached to a tool attachment surface of an arm member with an insulating plate therebetween, insulation members that electrically insulate bracket fixing implements and fix the bracket body to the tool attachment surface from the inside and the bracket body from each other, and an insulating cover that has electrical insulation properties and that is disposed inside the bracket body. Each of the bracket body, the insulating plate, and the insulating cover has a hollow hole through which an umbilical member is passed into an interior of the bracket body from inside the arm member. The bracket fixing implements include bolts that are fastened to screw holes in the tool attachment surface. The insulating cover covers a gap between the hollow hole of the bracket body and the umbilical member and is fixed to the bracket body by the bolts.
