Vapour Condenser Placement for Robot Atmosphere Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial cleaning installations for machined metal parts, particularly in the automotive industry, face challenges in maintaining a favorable atmosphere for industrial robots due to vapour and mist created during cleaning processes, which can reduce robot lifespan and increase maintenance complexity.
Innovation Solution
The installation features a vapour condenser arranged below the platform, with intakes positioned below the upper half of the workspace to improve air flow dynamics and reduce vapour exposure to the robot, combined with a heat recovery unit and simplified ductwork and maintenance access, including a cabinet-type enclosure for the vapour condenser.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vapour condenser is installed in the workspace to remove vapours, then the atmosphere for the robot is improved, but the device complexity and maintenance procedures increase
Solution Approach 1:
The vapour condenser is extracted from the workspace and installed outside the housing. The intake for admitting vapour-charged air is positioned at the lower half of the workspace, separating the condensation function from the robot operating space while maintaining effective vapour removal.
Solution Approach 2:
A ductwork system serves as an intermediary between the workspace and the externally installed vapour condenser. The ductwork with intake at the lower half of the workspace transports vapour-charged air to the condenser located outside the housing, enabling vapour removal without placing complex equipment inside the workspace.
2Reliability
If the vapour condenser is placed inside the workspace, then vapour removal is effective, but maintenance access becomes difficult
Solution Approach 1:
The vapour condenser is extracted from the workspace environment and installed externally on the housing. The intake is positioned at the lower half of the workspace to maintain effective vapour extraction, while the condenser itself is located where maintenance personnel can easily access it for servicing.
Solution Approach 2:
The ductwork system acts as a mediator that connects the workspace intake (positioned at lower half) to the externally located vapour condenser, enabling effective vapour removal while keeping the maintenance-required equipment outside the workspace for easy access.
3Reliability
If air recirculation is implemented to maintain stable atmosphere, then robot operating conditions improve, but energy loss increases
Solution Approach 1:
The system recovers heat from the vapour-charged air before it enters the vapour condenser. The heat recovery unit captures thermal energy that would otherwise be lost during condensation and uses it to pre-heat the air being recirculated back to the workspace, reducing overall energy consumption while maintaining stable atmosphere.
4Reliability
If intakes are positioned at upper half of workspace, then vapour extraction is effective, but robot exposure to vapour increases
Solution Approach 1:
The intake is specifically positioned at the lower half of the workspace where vapour accumulates due to its higher density, creating a localized extraction zone that targets vapour sources effectively while keeping the upper workspace area (where the robot operates) relatively free from vapour exposure.
