Component Mounting Method With Cross Lane Alternate Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting apparatuses face inefficiencies in operation due to limited flexibility in component arrangement and supply management, particularly when component remaining numbers approach zero, leading to interruptions in the mounting process.
Innovation Solution
The component mounting method employs a configuration with two board transport lanes, two mounting heads, and two component suppliers, allowing for independent and cross-lane alternate mounting modes. This configuration enables efficient component pickup and placement on boards by optimizing the movement of mounting heads and suppliers based on component availability, reducing the need for frequent replenishment and enhancing operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a component mounting apparatus uses a fixed component arrangement and single-lane mounting, then the device complexity is reduced, but the productivity and operational efficiency deteriorate due to frequent interruptions when component supplies are low
Solution Approach 1:
The system segments the mounting operation into two independent board transport lanes with separate mounting heads, allowing parallel processing of different boards. This segmentation enables continuous productivity even when one lane experiences component supply issues, as the other lane can continue mounting operations independently.
Solution Approach 2:
The component suppliers are designed with universal functionality to supply components to multiple mounting heads across different lanes. The first component supplier can supply both the first and second mounting heads, and the second component supplier can also supply both mounting heads, creating a flexible supply network that adapts to varying component availability and mounting requirements.
2Ease of operation
If the component supplier is disposed closer to one board transport lane, then the ease of operation for that lane is improved, but the productivity deteriorates due to increased mounting head movement distance for the other lane
Solution Approach 1:
Each component supplier is configured to supply components to multiple mounting heads across different lanes. The first component supplier supplies both the first mounting head (closer lane) and the second mounting head (farther lane), and vice versa for the second component supplier. This multi-functional supply capability ensures that mounting heads can efficiently pick up components without excessive movement, maintaining high productivity across both lanes.
Solution Approach 2:
The component suppliers act as intermediaries that bridge the gap between component storage and multiple mounting heads. By positioning component suppliers strategically and enabling them to supply multiple lanes, the system reduces the movement distance for mounting heads while maintaining ease of operation for each lane.
3Adaptability or versatility
If the system uses asynchronous transport with independent mounting, then the adaptability to different component supplies is improved, but the productivity deteriorates due to idle time when components are unavailable
Solution Approach 1:
The system segments the mounting operation into independent lanes that can operate asynchronously. When components are unavailable in one lane, the other lane can continue mounting operations without interruption. This segmentation isolates the impact of component unavailability to specific lanes, maintaining overall productivity and continuity across the system.
Solution Approach 2:
The universal supply capability of component suppliers allows them to redirect components to different mounting heads based on availability and demand. When one mounting head experiences component unavailability, the system can dynamically allocate components from alternative suppliers to other lanes, maintaining adaptability while minimizing idle time and preserving productivity.

AI summary
A component mounting method includes independent mounting and cross lane alternate mounting. The independent mounting performs an operation of mounting a component on a first board carried in a first board transport lane from a first component supplier, and an operation of mounting a component on a second board carried in a second board transport lane from a second component supplier. The cross lane alternate mounting alternately performs an operation of mounting the component on the first board carried in the first board transport lane from the second component supplier, and an operation of mounting the component on the second board carried in the second board transport lane from the first component supplier.
