Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component mounting devices face inefficiencies due to suboptimal feeder positioning, difficult feeder changes, and challenging rectification of feeding errors and pick-up position settings, leading to slow mounting speeds and increased operational complexity.
Innovation Solution
An electronic component mounting device with a movable frame that allows feeders to be easily attached and detached, and a camera-based system for precise positioning and error rectification, enabling optimal feeder placement and quick changes, along with a method for determining and adjusting pick-up positions using pattern recognition techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If feeders are fixed in position, then structural simplicity is maintained, but mounting speed decreases due to suboptimal positioning
Solution Approach 1:
The feeder support structure is designed to be movable rather than fixed, allowing dynamic adjustment of feeder positions along the conveyor direction. This enables optimization of the distance between feeders and pick-up devices, thereby increasing mounting speed while maintaining acceptable structural complexity through controlled mobility.
Solution Approach 2:
The feeder support structure is divided into separate movable components that can be independently adjusted. This segmentation allows selective optimization of feeder positions without requiring complete redesign of the entire support structure, balancing productivity improvement with structural simplicity.
2Ease of operation
If feeders are detachable, then ease of changing feeders is improved, but mounting speed decreases due to time-consuming feeder changes
Solution Approach 1:
The feeder support structure is pre-configured with detachable connections at optimal positions, allowing feeders to be quickly attached and detached without requiring repositioning operations. This preliminary preparation of the support structure enables rapid feeder changes while minimizing interruption to the mounting process.
3Ease of operation
If pick-up positions are fixed, then device simplicity is maintained, but difficulty in setting pick-up positions increases
Solution Approach 1:
The pick-up device is equipped with adjustable positioning mechanisms that allow dynamic modification of pick-up positions along the conveyor direction. This dynamic capability enables easy adaptation to different feeder positions and component types while maintaining manageable complexity through standardized adjustment interfaces.
4Productivity
If feeders are positioned far from pick-up device, then ease of feeder installation is improved, but mounting speed decreases
Solution Approach 1:
The feeder support structure incorporates movable elements that can be easily repositioned along the conveyor direction during installation and operation. This dynamic positioning capability allows installers to adjust feeder locations to optimal distances from pick-up devices while maintaining ease of installation through simple repositioning operations rather than complex assembly procedures.
