Welding Robot Direct Teaching With Separated Switch and Button
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In direct teaching operations of arc welding robots, operators may inadvertently activate unintended functions due to pressing buttons during precise movements, leading to inefficiencies and errors.
Innovation Solution
A robot system with a switch portion that remains on during direct operation and disables specific button functions, preventing erroneous activations by separating the switch and button positions on the robot arm or torch mount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If buttons are provided on the grip portion for direct operation, then the operator can easily access functions, but the operator may erroneously press buttons during direct operation while not looking at the grip portion
Solution Approach 1:
The invention extracts the button from the grip portion and relocates it to a different position on the robot arm or attached member. This spatial separation ensures that the button is not accidentally pressed during direct operation when the operator is focused on the tool tip rather than the grip portion.
Solution Approach 2:
The switch portion acts as an intermediary mechanism between the operator's intent and the button function. The button operation is conditioned on the switch portion being in the on state, creating an intermediate control layer that prevents erroneous activations while maintaining intentional control.
2Device complexity
If the switch portion and button are integrated on the same component, then the structure is simplified, but the operator may accidentally activate functions during precise movements
Solution Approach 1:
The invention segments the control system into two distinct components: the switch portion and the button. These are positioned on different components of the robot arm or attached member, creating physical and functional separation. This segmentation prevents simultaneous or accidental activation while maintaining operational control.
Solution Approach 2:
The button is extracted from the same component as the switch portion and relocated to a different position. This extraction ensures that during precise movements when the operator focuses on the tool tip, the button cannot be accidentally pressed along with the switch portion.
3Productivity
If the button remains accessible during direct operation, then the operator can quickly access functions, but the specific function may be erroneously activated during direct teaching
Solution Approach 1:
The button's functionality is made dynamic through the switch portion. The button only activates the specific function when the switch portion is in the on state. During direct operation, the switch portion can be positioned to disable the button, preventing erroneous activation while maintaining quick access capability when needed.
Solution Approach 2:
The switch portion serves as an intermediary control that mediates between the button and the specific function. It creates a conditional activation mechanism where the button's effect is controlled by the switch state, allowing the operator to enable or disable the function based on the operational context.

AI summary
A robot system includes: a welding torch portion attached to a distal end of a robot arm; a switch portion that causes, when switched to an on state, the robot to be operable according to an external force; a button to which a specific function is assigned; a mode setting unit that sets an operation mode for operating the robot; and an operation disabling unit that disables an operation on the button while the operation mode is set to a direct operation mode in which an operator directly applies the external force to the robot by hand and operates the robot by moving the robot according to the external force, and the switch portion is maintained in the on state, in which the switch portion and the button are provided on any one of the robot arm or a member attached to the robot arm and attached at a position different from the tool portion.
