Elastic Teaching Tip for Damage-Free Welding Robot Teaching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teaching tips for welding robots require the power feeding tip to be removed and reattached during teaching, which can damage the workpiece surface and are cumbersome to use.
Innovation Solution
A removably attachable teaching tip made of resin or rubber with an insulating property, featuring a recessed portion to house the power feeding tip, allowing secure attachment without removal, and an elastic design to prevent workpiece damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power feeding tip is removed and reattached during teaching, then the teaching tip can be used for teaching the welding robot, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The teaching tip is nested within the power feeding tip, allowing the teaching tip to be inserted into and removed from the power feeding tip without removing the power feeding tip itself from the welding torch. This nested structure enables easy replacement of the teaching tip while maintaining the power feeding tip in place, resolving the contradiction between ease of operation and workpiece protection.
Solution Approach 2:
The teaching tip acts as an intermediary tool that can be temporarily attached to the power feeding tip during teaching operations. This intermediary structure allows teaching to be performed without using the actual power feeding tip, preventing workpiece damage while maintaining operational simplicity through the removable design.
2Object-affected harmful factors
If the teaching tip is made of elastic resin or rubber, then the workpiece surface is protected from damage, but the structural complexity increases
Solution Approach 1:
The teaching tip changes its physical parameters by being made from elastic resin or rubber material instead of rigid materials. This parameter change in material properties provides inherent cushioning and protection against workpiece surface damage while maintaining a relatively simple overall structure through the single-piece elastic design.
Solution Approach 2:
The teaching tip utilizes composite material properties by combining elastic resin or rubber with conductive elements (such as metal wires or conductive coatings) to achieve both workpiece protection through elasticity and electrical conductivity for welding teaching functions, resolving the contradiction between protection and structural simplicity.

AI summary
A teaching tip is removably attached to a distal end portion of a power feeding tip and is an elastic body made of a resin or rubber having an insulating property. The teaching tip has a base end into which the distal end portion of the power feeding tip is inserted. A tip housing recessed portion is formed to be allowed to be attached and detached to/from the power feeding tip. The tip housing recessed portion has an abutting surface abutting on the distal end surface of the power feeding tip. A distance along a longitudinal direction from the abutting surface to a distal end of the teaching tip is set to a specified length.
