Welding Robot Conduit Layout for Dust-Free Wire Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robots face challenges in preventing dust intrusion and bending of welding wires due to the design of conduit pathways, which can lead to wire damage and accumulation of cutting powder.
Innovation Solution
A robot design featuring a first base, a robot arm with a rotation arm member, and a second base where the conduit is introduced through an arm member opening and pulled out through a side opening of the second base, increasing the curvature radius and reducing dust intrusion and wire bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conduit is introduced through the rotation arm member and base from the upper side, then the welding wire can be supplied to the robot arm, but the conduit causes dust intrusion and wire bending
Solution Approach 1:
The patent changes the spatial arrangement by introducing the conduit from the side direction rather than from the upper side through the rotation arm member. The conduit is routed through a conduit introducing portion in the base body, changing the entry dimension from vertical (upper side) to horizontal (side direction), thereby avoiding the rotation arm member interior and preventing dust intrusion and wire bending issues
Solution Approach 2:
The patent extracts the conduit routing path from the rotation arm member and base interior, separating the wire supply function from the rotating components. The conduit is now introduced through a dedicated conduit introducing portion in the base body, outside the rotation arm member, thereby eliminating the harmful effects of dust accumulation and wire bending that occurred when the conduit passed through the rotation arm member interior
2Ease of operation
If the conduit passes through the rotation arm member interior, then wire feeding is enabled, but dust accumulates and cutting powder builds up
Solution Approach 1:
The patent extracts the conduit routing from the rotation arm member interior and relocates it to the base body through a dedicated conduit introducing portion. This separation removes the conduit from the rotating component interior, eliminating the environment where dust and cutting powder would accumulate, while still enabling wire feeding functionality
Solution Approach 2:
The patent introduces a dedicated conduit introducing portion in the base body as an intermediary structure for wire supply. This intermediary component handles the wire feeding function separately from the rotation arm member, preventing dust and cutting powder from accumulating in the wire path while maintaining efficient wire delivery to the robot arm

AI summary
A robot is provided with a first base, a robot arm having a rotation arm member, and a second base. A bottom end portion of the first base is fixed to an upper end portion of the second base using a fixing member, the rotation arm member includes an arm member opening, the second base includes an upper surface having an upper opening and a side surface having a side opening, the rotation arm member and the first base are configured to allow the conduit containing the welding wire and introduced into an interior of the rotation arm member through the arm member opening to reach the upper opening, the side opening allows the conduit introduced into an interior of the second base through the upper opening to come out of the second base.
