Robotic Scraping of Honeycomb Segment Joints Before Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual scraping of excess joining material from segment joint bodies in pillar-shaped honeycomb structures is labor-intensive and costly, exacerbated by labor shortages, leading to increased production costs and potential defects like sinks and cracks.
Innovation Solution
A robotic scraping device with controlled scraping spatulas that can move along the honeycomb-shaped surfaces, adjusting pressing load, angle, and speed to efficiently remove undried joining material, reducing manual labor and improving joint integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual scraping of joining material is performed, then the protruding joining material can be removed, but labor cost increases and labor shortage becomes serious
Solution Approach 1:
The scraping device is designed to automatically perform the scraping operation without manual intervention. The robot moves the scraping spatula along the segment joint body, and the system self-regulates the scraping process through controlled movement and pressing force, eliminating the need for manual labor while maintaining effective removal of protruding joining material.
Solution Approach 2:
The patent replaces the manual mechanical scraping operation with an automated robotic system. The robot-controlled scraping spatula substitutes human hands and tools, transforming a labor-intensive manual process into an automated mechanical system that can consistently perform scraping without human intervention.
2Manufacturing precision
If scraping is performed to remove protruding joining material, then surface defects like sinks and cracks are prevented, but production time increases
Solution Approach 1:
The scraping operation is performed while the joining material is still undried and pliable, before it hardens and becomes difficult to remove. This timing allows for efficient removal of excess material with minimal effort and time, preventing the need for more intensive removal operations later that would consume additional time and potentially damage the surface.
Solution Approach 2:
The scraping device incorporates dynamic control of the scraping spatula's movement speed, pressing force, and angle. The robot can adjust these parameters in real-time based on the state of the joining material and the specific location being scraped, optimizing the scraping efficiency to maintain high production speed while ensuring quality surface finish.
3Strength
If excessive joining material is applied to segments, then complete coverage and bonding are achieved, but protrusion occurs requiring scraping
Solution Approach 1:
The scraping device controls the removal process by adjusting parameters such as pressing force, scraping angle, and movement speed. By dynamically modifying these parameters, the system can selectively remove only the protruding excess material while preserving the adequate thickness and coverage of the joining material needed for strong bonds, thus maintaining both joint strength and surface flatness.
