Movable Electric Discharger for Static Removal in Processing Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional processing machines require multiple fixed electric dischargers and manual cleaning, which are inefficient and disrupt machine operation, as they only address static electricity in specific areas and not across a wide range.
Innovation Solution
A movable electric discharger system integrated with an imaging device and movement means, such as a robot, that allows for automated detection and removal of static electricity across a wide range without obstructing machine operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple fixed electric dischargers are installed to cover a wide area, then static electricity removal coverage is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies the dynamics principle by transforming fixed electric dischargers into movable ones. The electric discharger is mounted on a moving mechanism (such as a robot arm or linear guide) that enables it to travel to different positions within the processing chamber. This single movable discharger can sequentially service multiple areas, replacing the need for multiple fixed dischargers and thereby reducing device complexity while maintaining wide area coverage.
Solution Approach 2:
The movable electric discharger serves multiple functions by visiting different locations at different times. Rather than having dedicated dischargers for each zone, one universal discharger performs the static electricity removal function across the entire workspace through movement, achieving multi-functionality with a single device.
2Object-affected harmful factors
If manual cleaning is performed to remove machining chips, then adhesion problems are addressed, but productivity decreases due to machine stoppage
Solution Approach 1:
The electric discharger performs preliminary action by removing static electricity from machining chips and workpieces before the chips can adhere to surfaces. By neutralizing the electrostatic charge that causes adhesion, the system prevents the harmful effect rather than addressing it after occurrence, thereby eliminating the need for subsequent manual cleaning operations and maintaining continuous productivity.
Solution Approach 2:
The system converts the harmful static electricity that causes chip adhesion into a beneficial control mechanism. By detecting and neutralizing static charge, the electric discharger transforms the problematic electrostatic attraction into a controlled process where chips remain suspended or fall naturally without adhering to machine surfaces, eliminating the need for machine stoppage and manual intervention.
3Device complexity
If a single fixed electric discharger is used, then device complexity is reduced, but coverage area is limited
Solution Approach 1:
The patent resolves this contradiction by making the single electric discharger movable rather than fixed. The discharger is equipped with a movement mechanism that allows it to travel to different positions within the processing chamber, enabling one device to cover the entire workspace over time while maintaining simplicity in the number of dischargers used.
