Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing component supply devices experience delays in component supply, leading to increased cycle time in mounting work due to the time required for component return and redisperse operations.
Innovation Solution
A component supply device with a feeder vibration mechanism, imaging device, and control device that determines the necessary number of components and calculates the number of holdable components, allowing for timely redisperse and return operations to maintain efficient component supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If component return and redisperse operations are performed, then components can be supplied continuously, but cycle time increases due to the time required for these operations
Solution Approach 1:
The imaging device captures images of components in advance before the holding tool attempts to pick them up. This allows the control device to pre-determine which components are holdable and prepare for the next pickup operation, overlapping the imaging and determination processes with the component return and redisperse operations. By performing these preparatory actions beforehand, the system minimizes idle time and prevents cycle time extension despite the additional return and redisperse operations.
2Quantity of substance
If components are returned to component container and redispersed, then holdable components can be replenished, but supply speed decreases due to return and dispersal operations
Solution Approach 1:
The imaging device continuously monitors the component support section and provides real-time information to the control device about component positions and holdability. This feedback mechanism allows the system to dynamically adjust the pickup process, immediately identifying when holdable components are depleted and triggering the return and redisperse operations at the optimal moment. The control device uses this feedback to coordinate the timing of pickup operations with replenishment operations, maintaining supply speed by ensuring that return and redisperse operations are initiated precisely when needed rather than operating on fixed schedules.

AI summary
In a component mounting machine that carries out mounting work of components that are supplied by a component supply device, the component supply device has a component storage device that stores a plurality of components, a component support member 220 on which the components from the component storage device are dispersed, and a component return device that returns the components on the component support member to the component storage device. Then, it is determined whether or not the necessary number of components that is the number of components that are necessary during mounting work exceeds the number of holdable components that is a number of components that are holdable from the component support member. At this time, in a case where the necessary number of components exceeds the number of holdable components, return work of the components to the component container and dispersal work of the components to the component support section are carried out prior to holding the components from the component support section by the component holding tool. Thereby, it is possible to carry out return work and dispersal work of the components with good timing, and reduction of the cycle time of mounting work by the mounting work machine is prevented.
