Parallel Link Robot Oil Tray Segmentation and Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parallel link robots face challenges in maintaining the cleanliness and reliability of delicate products handled, such as food, medicinal products, and cosmetics, due to the difficulty in inspecting, cleaning, and performing maintenance on the oil trays and other components without causing contamination or damage.
Innovation Solution
A parallel link robot design featuring a detachable oil tray with an oil absorbent sheet and horizontally extending screw holes to prevent oil and grease from dripping, allowing for easy inspection and maintenance, and a configuration that prevents installation bolts from falling and causing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the oil tray is fixed to the main body, then oil collection is effective, but maintenance and cleaning become difficult
Solution Approach 1:
The oil tray is divided into a tray body and a detachable cover, allowing the cover to be removed for easy access to the oil reservoir while the tray body remains attached to collect oil. This segmentation enables effective oil collection while facilitating maintenance and cleaning operations.
Solution Approach 2:
The cover is designed to be detachable rather than fixed, allowing it to be removed when maintenance is needed and attached during normal operation. This dynamic design enables the system to switch between oil collection mode and maintenance mode, resolving the contradiction between effective oil collection and ease of maintenance.
2Ease of manufacture
If vertical screw holes are used for oil tray attachment, then installation is simple, but bolts may fall and cause contamination
Solution Approach 1:
Instead of using vertical screw holes that extend downward where bolts could fall, the invention uses horizontal screw holes that extend laterally. This inverted orientation prevents bolts from falling into the oil reservoir or onto the movable plate, eliminating the contamination risk while maintaining installation simplicity.
3Reliability
If the oil tray structure is complex, then oil leakage is prevented, but cleaning and inspection become difficult
Solution Approach 1:
The oil tray is segmented into a stationary tray body and a detachable cover. The tray body provides the oil reservoir with leakage prevention features, while the detachable cover provides easy access for cleaning and inspection. This segmentation allows the system to have both complex leakage prevention mechanisms and simple accessibility for maintenance.
Solution Approach 2:
The cover is extracted as a separate detachable component from the tray body. This extraction allows the cover to be removed completely for cleaning and inspection operations, while the tray body remains in place to continue preventing oil leakage during normal operation.
4Reliability
If the oil tray is permanently attached, then oil collection reliability is improved, but maintenance frequency increases due to contamination risks
Solution Approach 1:
The oil tray system uses a dynamic attachment design where the cover can be detached for maintenance and reattached afterward. This dynamic design maintains oil collection reliability during operation while enabling quick maintenance interventions when contamination is detected, reducing overall maintenance time compared to permanently fixed designs that require complete disassembly for any maintenance.
