Automatic Welding Tip Replacement With Continuous Tip Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional welding tip supplying apparatuses for welders face challenges such as prolonged replacement times, instability in replacing welding tips, and the inability to easily monitor the availability of welding tips, leading to decreased productivity and potential errors in manufacturing processes.
Innovation Solution
The proposed apparatus includes a fixed bracket, an actuator, and various moving members to facilitate the automatic removal and replacement of welding tips, along with a sensor system to monitor the availability of welding tips and prevent errors. This apparatus is designed to minimize the moving trajectory of the robot welder, enhance work efficiency, and ensure continuous supply of welding tips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional welding tip supplying apparatus is used, then welding tips can be supplied to the welder, but the replacement time is prolonged and the replacing work is unstable
Solution Approach 1:
The apparatus pre-positions multiple welding tips in an accommodation case before they are needed. The welding tips are arranged in advance with their inserting portions facing a predetermined direction, so that when replacement is needed, the welder can immediately pick up a pre-positioned tip without requiring time-consuming manual arrangement or search.
Solution Approach 2:
The accommodation case is designed to automatically maintain the welding tips in the correct orientation through its structural features (such as guiding walls and positioning structures). The tips self-align within the case during loading and storage, eliminating the need for manual intervention to position them correctly before each replacement operation.
2Loss of information
If a conventional welding tip supplying apparatus is used, then welding tips are supplied to the welder, but it is difficult to monitor the availability of welding tips from the outside
Solution Approach 1:
The accommodation case incorporates transparent or translucent portions that allow visual inspection of the welding tips inside. This enables operators to easily determine whether welding tips are available and how many remain without needing to open the case or access internal sensors, providing immediate visual feedback on tip availability.
3Reliability
If the accommodation case is replaced before all welding tips are used, then continuous supply is maintained, but the replacing work is inconvenient and manufacturing lines may be affected
Solution Approach 1:
The accommodation case is designed to hold a large capacity of welding tips in advance. By pre-loading the case with sufficient tips to cover extended operation periods, the frequency of case replacements is reduced, allowing the welder to complete more welding tasks before needing to replace the entire accommodation case.
Solution Approach 2:
The apparatus enables the welder to continuously access welding tips from the accommodation case without interruption to the welding process. The case is designed to maintain tip availability throughout its service life, ensuring that the welding operation can proceed continuously without stopping for case replacements until the tips are depleted.
4Extent of automation
If multiple moving members are used for welding tip replacement, then automatic replacement is achieved, but the device structure becomes complex
Solution Approach 1:
The replacement apparatus is divided into functionally independent moving members, each responsible for a specific task in the replacement sequence. This segmentation allows each component to be simple in structure while collectively achieving complex automated replacement functionality. Each moving member can be controlled independently, simplifying the overall control logic.

AI summary
An apparatus for supplying a welding tip of a welder and an apparatus for replacing the same include a fixed bracket secured to a support. The apparatus includes an actuator coupled to the fixed bracket and a first moving member moved by the actuator. A second moving member is coupled to the first moving member and hingedly coupled to the fixed bracket. A third moving member is hingedly coupled to the second moving member. A first welding tip removal member is coupled to the third moving member to separate a welding tip coupled to a shank. A fourth moving member is disposed opposite to the first moving member. A fifth moving member is coupled to the fourth moving member and hingedly coupled to the fixed bracket. A sixth moving member is coupled to the fifth moving member. A second welding tip removal member is coupled to the sixth moving member.
