Substrate Conveyance Prioritizing Proximity to Component Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting apparatuses with multiple substrate conveying lanes, the conventional method of determining substrate entry order based on signal output leads to inefficiencies, as substrates are often carried into lanes farther from the component supplying unit even when closer lanes are ready, resulting in uneven mounting efficiency and reduced productivity.
Innovation Solution
A substrate conveyance controlling unit dynamically determines the entry order by detecting the availability of substrates in each lane and prioritizing entry into lanes closest to the component supplying unit, ensuring optimal substrate distribution and mounting efficiency.

Engineering Contradiction Analysis
1Productivity
If substrates are carried into substrate conveying lanes in the order of substrate request signals, then the control logic is simple, but the component mounting efficiency decreases because substrates may be carried into lanes farther from the component supplying unit
Solution Approach 1:
The substrate distributing control dynamically adjusts the substrate request signal output order based on real-time detection of which substrate conveying lanes are ready to receive substrates and their distances from the component supplying unit. The control selectively outputs substrate request signals to prioritize lanes closer to the component supplying unit, making the control system adaptive rather than static.
Solution Approach 2:
The substrate conveying lane readiness detection mechanism provides feedback information about the status of each substrate conveying lane to the substrate distributing control. This feedback enables the control to make informed decisions about which lane to assign the next substrate to, optimizing the distribution based on current system state rather than following a fixed sequence.
2Productivity
If multiple substrate conveying lanes are used to improve productivity, then the overall output increases, but the mounting efficiency becomes uneven across different lanes
Solution Approach 1:
The system applies different treatment to different substrate conveying lanes based on their local characteristics, specifically their distance from the component supplying unit. Lanes closer to the component supplying unit are prioritized for receiving substrates, creating a non-uniform distribution strategy that optimizes for the most efficient mounting locations.
Solution Approach 2:
The substrate distributing control changes the operational parameters of the substrate conveying system by dynamically adjusting which lanes receive substrates based on detected readiness states and positional relationships. This parameter adjustment ensures that substrates are preferentially assigned to lanes that can process them most efficiently.

AI summary
An object of the invention is to provide a component mounting apparatus which includes a plurality of substrate conveying lanes and which efficiently controls the order of carrying in of substrates, thereby capable of improving productivity, and also is to provide a substrate conveyance method in the component mounting apparatus. In a configuration which includes: component supplying units (20A, 20B) positioned lateral to conveyor lines including conveyors (10A, 10B, 10C, 10D) arranged in parallel; and a substrate distributing unit (M3B) configured to distribute substrates (13) delivered from an upstream apparatus, in the case where a substrate request signal (R) is output for a plurality of conveyors, a new substrate (13) is carried in from the substrate distributing unit (M3B) into conveyors (10A, 10D) which are closest to the component supplying units (20A, 20B) among the conveyors (10A, 10B, 10C, 10D). Therefore, substrates can be preferentially carried into conveyors which are more advantageous in component mounting efficiency.
