Sealed Box Motor Cooling for Compact Work Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work transfer apparatuses for carrying plate-shaped works are bulky due to the arrangement of driving motors in an atmospheric-pressure space, which affects the overall size and efficiency, especially when dealing with high-temperature works that require cooling of peripheral components.
Innovation Solution
A compact work transfer apparatus with a sealed box that houses the driving source and includes a coolant circulation path for cooling, allowing the motors to be isolated from atmospheric pressure and reducing the apparatus's size by integrating the cooling system within the sealed environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving motors are arranged in atmospheric-pressure space, then motors are protected from vacuum conditions, but the fixed base becomes large and the overall apparatus size increases
Solution Approach 1:
The patent merges the motor housing with the vacuum chamber structure. The driving motors are mounted directly on the vacuum chamber wall, integrating two previously separate components (motor housing and vacuum chamber) into a single unified structure. This eliminates the need for a separate atmospheric-pressure space for motor protection, thereby reducing the overall apparatus size while maintaining motor reliability through the sealed vacuum environment.
Solution Approach 2:
The patent employs sealed structures and gaskets to create a vacuum-tight barrier that protects motors from vacuum conditions. By using flexible sealing elements and thin-film barriers at the motor mounting interface, the motors are protected from direct vacuum exposure while being compactly integrated into the vacuum chamber structure, avoiding the need for bulky protective housings.
2Temperature
If link arm mechanism is exposed to radiant heat from high-temperature work, then cooling systems must be added, but this increases device complexity
Solution Approach 1:
The cooling system is merged with the vacuum chamber structure. The vacuum chamber wall itself serves as a cooling structure, with coolant channels integrated into the chamber wall thickness. This eliminates the need for separate cooling jackets or external cooling apparatus, reducing device complexity while providing effective thermal management for components exposed to radiant heat from high-temperature work.
Solution Approach 2:
The patent implements localized cooling only in the regions of the vacuum chamber that are exposed to radiant heat from the work. Rather than cooling the entire apparatus, coolant channels are strategically positioned in the chamber wall at locations receiving thermal radiation, providing targeted thermal management that reduces complexity compared to comprehensive cooling systems.
3Temperature
If coolant circulation path is added to sealed box, then driving source can be cooled effectively, but the sealed box structure becomes more complex
Solution Approach 1:
The coolant circulation path is merged with the sealed box structure by integrating cooling channels directly into the box walls. The sealed box serves dual functions as both the vacuum-tight enclosure and the cooling system housing. This integration eliminates the need for separate cooling manifolds, hoses, and external cooling components, reducing structural complexity while maintaining effective cooling of the driving source.

AI summary
A work transfer apparatus includes a work carrying mechanism, a driving source that drives the work carrying mechanism, a sealed box that accommodates the driving source in a hermetically sealed state, and a coolant circulation path provided in the sealed box for cooling the driving source. The sealed box includes a box body with an opening, and a partition lid for closing the opening. The partition lid includes an outer plate member and an inner plate member superposed on the outer plate member. The coolant circulation path is disposed at the interface between the outer plate member and the inner plate member.
