Substrate Production Line Using Shared Folder Type Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional substrate production lines require costly cameras for each machine to read substrate types and enable communication between machines, which is not feasible without a communication function, limiting productivity and increasing costs.
Innovation Solution
A substrate production line configuration where a shared folder is used to create and recognize substrate type information files, allowing upstream machines to grasp the substrate type and downstream machines to receive this information without needing a communication function between machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera for reading substrate type is provided for each substrate production machine, then each machine can independently identify substrate type, but costs increase and space requirements increase
Solution Approach 1:
Multiple substrate type reading cameras that were previously distributed across different machines are merged into a single shared camera located at the upstream machine. This single camera serves all downstream machines, reducing the total number of cameras from N (one per machine) to 1, thereby reducing costs and space requirements while maintaining identification reliability through centralized operation
Solution Approach 2:
The upstream substrate type reading camera is given a universal function to serve multiple downstream machines simultaneously. Instead of each machine having its own dedicated camera, the single upstream camera performs the substrate type identification function for the entire production line, and this information is then distributed to all machines that need it
2Productivity
If data transfer means is added to enable communication between machines, then substrate type information can be transferred efficiently, but device complexity and cost increase
Solution Approach 1:
A shared folder is introduced as an intermediary data storage mechanism between the upstream camera and downstream machines. Instead of implementing direct communication protocols or data transfer means between machines, the system uses a common folder that all machines can access, allowing substrate type information to be stored and retrieved without requiring complex inter-machine communication infrastructure
Solution Approach 2:
Downstream machines independently access and retrieve substrate type information from the shared folder without requiring active data transfer from the upstream machine. Each machine serves itself by reading the necessary information from the common folder, eliminating the need for complex push-based communication systems
Data Source
AI summary
A substrate production line including multiple substrate production machines arranged in a line; a shared folder in which an electronic file from each of the substrate production machines can be created and recognized; a substrate type grasping section on the substrate production machine furthest upstream in the line to grasp the type of the substrate; a file creating section on the substrate production machine other than the substrate production machine furthest downstream in the line to create in the shared folder a substrate type information file including substrate type information indicating the type of the substrate in accordance with unloading of the substrate; and a file recognizing section on the substrate production machine other than the substrate production machine furthest upstream in the line to recognize the substrate type information file created by the substrate production machine directly adjacent at the upstream side before the substrate is loaded.
