Rotating Nozzle Cleaning Apparatus for Workpiece Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning apparatuses are inadequate in cleaning workpieces of varying shapes as the cleaning fluid jet does not effectively reach all corners, leading to incomplete cleaning.
Innovation Solution
A cleaning apparatus with a rotating table and nozzles that can pivot to eject cleaning fluid perpendicular to the axis of rotation, ensuring thorough coverage of the workpiece, including deburring by air blow and high-pressure jet, utilizing multiple nozzles and a tilting mechanism to adjust the cleaning fluid's angle and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a cleaning apparatus uses a fixed nozzle to spray cleaning fluid onto a rotating table, then the structure is simple, but the cleaning fluid jet cannot reach all corners of the workpiece
Solution Approach 1:
The nozzle is made rotatable about a second axis while the table rotates about a first axis, creating dynamic cleaning coverage. This allows the cleaning fluid jet to impinge on all surfaces and corners of the workpiece during rotation, transforming a static single-direction cleaning system into a multi-directional dynamic system that achieves complete coverage.
Solution Approach 2:
The system adds a second rotational degree of freedom to the nozzle, moving from one-dimensional rotation (table only) to two-dimensional rotational movement (table + nozzle). This dimensional addition enables the cleaning fluid to reach all corners and surfaces of the workpiece regardless of its shape or size.
2Manufacturing precision
If the nozzle is made rotatable to clean all corners, then cleaning coverage improves, but the device complexity increases
Solution Approach 1:
A swivel fitting is introduced as an intermediary component between the nozzle and the rotating table mechanism. This swivel fitting allows the nozzle to rotate independently about a second axis while maintaining connection to the rotating table system, enabling complex motion without requiring a completely redesign of the mechanical linkage.
Solution Approach 2:
The rotational mechanism is segmented into two independent parts: the table rotation (first axis) and the nozzle rotation (second axis). This segmentation allows each component to perform its specific function independently, simplifying the control and mechanical design while achieving comprehensive cleaning coverage through the combination of both rotations.

AI summary
A cleaning apparatus capable of thoroughly cleaning all parts of a workpiece is provided. The cleaning apparatus includes: a cleaning chamber; a table rotation shaft that rotates about a first axis; a first swivel fitting disposed inside the table rotation shaft; a table on which the cleaning workpiece is placed; a first motor that rotates the table rotation shaft; a propeller shaft that rotates about a second axis that is parallel to the first axis; a second swivel fitting connected to a propeller shaft; and a nozzle that rotates integrally with the second swivel shaft and that ejects a cleaning fluid in a direction different from the second axis toward the cleaning workpiece.
