Electrode Cap Rotating Conduit for Automated Welding Magazine Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for managing electrode caps in welding robots require manual loading and interruption of the welding process for magazine replacement, leading to inefficiencies and safety concerns due to the need for reprogramming and manual handling within the robot cell.
Innovation Solution
An apparatus comprising an electrode cap rotating conduit connected to a heliconveyor for pre-positioning and transporting caps, a guide duct with a sensor for automatic replenishment, and a magazine loading unit with locking mechanisms and pneumatic cylinder for safe and automated feeding of caps into a dedicated magazine, ensuring continuous operation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual loading and magazine replacement is used, then the welding process can be interrupted for refilling, but this leads to loss of time and reduced productivity
Solution Approach 1:
The apparatus pre-positions electrode caps in a magazine before they are needed by the welding robot. The heliconveyor and rotating conduit prepare and store caps in advance, allowing automatic replacement without interrupting the welding process, thus eliminating downtime and maintaining productivity
Solution Approach 2:
The system enables automatic magazine replacement through the welding robot's own movements and the automated feeding mechanism. The robot picks up caps from the magazine and the apparatus automatically replenishes it, eliminating the need for manual intervention and continuous process interruption
2Ease of operation
If manual refilling is performed, then personnel can reload magazines, but this requires entering the danger zone of active robots which compromises safety
Solution Approach 1:
The magazine loading apparatus is automatically fed by the welding robot itself, which picks up caps from the magazine and returns them when empty. This self-service mechanism eliminates the need for personnel to enter the robot's danger zone, ensuring safety while maintaining ease of operation
Solution Approach 2:
The apparatus acts as an intermediary between the electrode cap supply and the welding robot. It provides a safe interface where caps are automatically transferred without requiring human presence in the hazardous robot workspace, thus protecting personnel while enabling continuous operation
3Adaptability or versatility
If coordinates are re-programmed after magazine mounting, then the welding tong can access new magazines, but this requires interruption of the welding process
Solution Approach 1:
The apparatus is designed with universal positioning features that work with standard welding robot coordinate systems. The magazine can be mounted in predefined positions that are already programmed into the robot, allowing the same coordinate set to work with different magazines without reprogramming, thus maintaining adaptability while eliminating reprogramming time
Solution Approach 2:
The magazine positions are pre-configured to match the robot's existing coordinate programming. The apparatus is designed so that magazines can be replaced without changing their position relative to the robot's coordinate system, allowing seamless operation without interruption for coordinate reprogramming

AI summary
A device for rotating, positioning, and introducing electrode caps for welding electrodes into a magazine. A rotating electrode cap channel is connected to a spiral conveyor. The electrode caps stand on a cap end-face provided with a bore on the spiral conveyor end, and they are rotated by 90°. The other end of the rotating electrode cap channel is arranged relative to the upper end of the guiding shaft such that vibrations of the spiral conveyor are not transmitted to the rest of the system. The openings of the rotating electrode cap channel and the guiding shaft are arranged relative to one another such that the electrode caps can be reliably transferred, and the guiding shaft is connected to the magazine filling unit at the lower end of the guiding shaft. The magazine connection has locking lever sensors, which detect the correct fit of the magazine.
