Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing processes for mounting electronic parts on printed circuit boards are costly due to investment in material preparation, labor, equipment, and clean room construction for taping, packing, and tape removal processes.
Innovation Solution
An apparatus and method that includes a bulk feeder, inspection units, a positioning wheel, and a part supply unit to inspect, align, and mount electronic parts in bulk form directly onto a printed circuit board, eliminating the need for conventional taping and packing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional taping and packing processes are used for electronic parts, then the parts can be properly handled and mounted, but investment costs, labor costs, and clean room construction costs increase enormously
Solution Approach 1:
The patent extracts and eliminates the taping and packing processes from the conventional electronic parts mounting system. By directly feeding bulk electronic parts into the mounting apparatus without requiring tape preparation, packing, or subsequent tape removal, the system removes unnecessary process steps while maintaining reliable part handling and mounting capabilities
Solution Approach 2:
The bulk feeder system enables electronic parts to be fed directly into the mounting apparatus in bulk form without requiring external taping or packing operations. The system serves itself by automatically handling bulk parts through the mounting process, eliminating the need for separate preparation and removal operations
2Productivity
If bulk feeder is used to feed electronic parts directly, then the process is simplified and costs are reduced, but the electronic parts must be properly classified and aligned before mounting
Solution Approach 1:
The patent applies preliminary classification and alignment actions to electronic parts before they enter the bulk feeder. The parts are pre-sorted by voltage, brightness, and color coordinates, and pre-aligned in bulk form, so that when they are fed into the mounting apparatus, they are already in the correct orientation and order, eliminating the need for complex real-time classification and alignment mechanisms

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach simplifies the process, reducing investment, labor, and clean room construction costs by directly mounting classified electronic parts from bulk form, achieving cost savings of approximately 530 million won compared to conventional methods.
Implementation Method 1
The first feeder may include an air blower to provide the electronic parts with air in order to align the electronic parts based on orientation of front and rear surfaces thereof
Implementation Method 2
a positioning wheel installed to rotate along the bulk feeder, the inspection unit, and the electronic part inspection unit and serving to transfer the electronic parts
Implementation Method 3
The positioning wheel may include a plurality of suction nozzles to suction and hold the electronic parts
