Electrode Tip Pick Plate Mechanism for Multi-Shape Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for replacing electrode tips in welding guns require multiple guns for different tip shapes, leading to inefficiencies and increased costs.
Innovation Solution
A replacing and holding device that uses two pick plates stacked together, guided by a rod, with a mechanism to increase the space between the plates, allowing for the removal, holding, and reattachment of electrode tips using a single welding gun.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple welding guns are prepared for different electrode tip shapes, then each gun can be optimized for its specific tip shape, but the number of guns and associated costs increase
Solution Approach 1:
The pick plate assembly is designed to accommodate multiple electrode tip shapes through a universal interface. The pick plates can be positioned and adjusted to work with different tip geometries, allowing a single welding gun to perform multiple functions that previously required separate dedicated guns for each tip shape
2Ease of operation
If electrode tips are removed using gravity alone, then the device structure is simple, but the removed tips cannot be held or reused
Solution Approach 1:
The pick plates serve as intermediary components between the electrode tip and the welding gun. These plates not only facilitate the removal of tips through simple mechanical action but also provide a holding mechanism that can securely retain removed tips for potential reuse, bridging the gap between simple removal and sophisticated retention
3Device complexity
If the space between pick plates is fixed, then the device structure is simpler, but it cannot effectively accommodate different electrode tip sizes and shapes
Solution Approach 1:
The pick plate assembly incorporates dynamic positioning capabilities where the plates can be adjusted to different positions and orientations. This dynamic adjustment allows the mechanism to adapt to various electrode tip sizes and shapes without requiring a completely different device configuration, maintaining structural simplicity while achieving versatility

Implementation Method 1
two pick plates stacked one another, the two pick plates being inserted between an end face of the electrode tip fitted into a shank fixed to a gun arm of a welding gun and an end face of a larger diameter portion of the shank
Implementation Method 2
a pick plate interspace increasing mechanism configured to increase a space between the two pick plates according to positions of the two pick plates guided along the guide rod
Implementation Method 3
a guide rod configured to guide motions of the two pick plates in a stacked direction thereof
Implementation Method 4
an electrode tip holder disposed in one of the two pick plates to hold the electrode tip pulled out from the shank
Implementation Method 5
an electrode tip contact portion provided in front of the shank in an insertion direction of the shank, wherein the electrode tip comes into contact by a motion of the welding gun to insert the shank into the electrode tip held by the electrode tip holder
