Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrostatic powder coating systems face inefficiencies in powder recovery, as residual powder often adheres to booth walls and projectors, requiring manual cleaning that interrupts operations and is time-consuming, especially when changing powder types or colors.
Innovation Solution
An electrostatic powder coating robot equipped with a robotic arm and blower that positions both the projector for coating and the blower for automated powder removal, allowing for efficient and versatile cleaning of surfaces within the booth, including walls, floor, and projectors, without the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual depowdering is performed by an operator, then the booth interior can be cleaned of residual powder, but the operation requires stopping the booth for safety reasons and consumes significant time
Solution Approach 1:
The system performs self-service depowdering through an automated robotic arm with integrated blower that cleans the booth interior without human intervention. The robot autonomously navigates and directs the blower to remove residual powder from surfaces, eliminating the need for operators to manually enter the booth and significantly reducing downtime between coating operations.
2Loss of substance
If a residual powder suction system is used, then most residual powder can be recovered for recycling, but powder still adheres to walls and floor requiring additional manual cleaning
Solution Approach 1:
The system extracts and removes residual powder adhering to walls and floor surfaces using a robotic arm equipped with a blower. This secondary extraction process complements the primary suction system by actively dislodging and removing powder that would otherwise remain attached to surfaces, enabling complete powder recovery and eliminating manual cleaning requirements.
3Extent of automation
If an automatic cleaning unit is introduced from the outside for each cleaning, then cleaning can be automated, but the process is time-consuming and the unit is bulky and suitable for only one booth shape
Solution Approach 1:
The cleaning system is integrated into the robotic arm that also performs powder coating application, creating a multi-functional device. The robotic arm can be reconfigured to carry different tools including projectors for coating and blowers for cleaning, making it universally applicable to various booth configurations and eliminating the need for specialized bulky cleaning units designed for specific booth shapes.
Solution Approach 2:
The blower and cleaning components are integrated within the robotic arm structure, with the cleaning tool nested within the same manipulator that carries the projector. This allows the cleaning function to be compactly housed within the existing robotic system rather than requiring a separate external unit, reducing space requirements and enabling faster deployment.

AI summary
An electrostatic powder coating robot (4) for a powder coating booth (2), the robot (4) including a projector (41) for performing electrostatic powder coating. To reduce the time required for de-powdering the booth and to facilitate the automation of de-powdering, the robot (4) further includes a robotic arm (43), which is articulated and carries the projector (41) for positioning the projector (41), as well as a blower (42) for blowing a de-powdering fluid, preferably air. The robotic arm (43) carries the blower (42) for positioning the blower (42) within the booth (2), so that the blower (42) blows the de-powdering fluid onto a surface to be de-powdered inside the electrostatic powder coating booth (2) and thus removes residual powder coating the surface to be de-powdered.
