Board Production Line Management Device for Test Process Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In board production lines, there is a risk of mistakenly starting the main production process before determining the quality of initial boards, leading to potential malfunctions and environmental disruptions during changeovers, especially when parameters are altered mid-test production.
Innovation Solution
A production management device with a permission determination section that inspects initial boards and determines whether to allow operation commands, and a processing management section that controls these commands to prevent malfunctions and maintain the production environment by restricting parameter changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operation commands are allowed during test production process, then operational flexibility is improved, but risk of malfunction and loss increases
Solution Approach 1:
The system dynamically adjusts the level of permission for operation commands based on the current production process state. During test production, permission is restricted to prevent malfunctions, while during main production, normal operational flexibility is restored. This dynamic control resolves the contradiction by adapting the permission level to the specific phase of production.
Solution Approach 2:
The permission determination section acts as an intermediary between the operation command input and the board production device execution. It intercepts and evaluates operation commands, determining whether to permit or reject them based on the current process state. This intermediary layer prevents direct execution of potentially harmful commands during test production while maintaining system operability during main production.
2Adaptability or versatility
If parameters are changed during test production process, then adaptability is improved, but production environment stability deteriorates
Solution Approach 1:
The system dynamically controls parameter change permissions based on the production process phase. During test production, parameter changes are restricted to maintain environmental stability, while during main production, parameter changes are permitted to enable adaptability. This dynamic permission control resolves the contradiction between adaptability and stability.
Solution Approach 2:
The permission determination section preemptively prevents parameter changes during test production by evaluating the current process state before allowing modifications. This preliminary anti-action blocks potential disruptions to production environment stability before they can occur, while still permitting necessary parameter changes during main production when stability is less critical.
3Productivity
If main production process is started early, then productivity is improved, but quality control deteriorates
Solution Approach 1:
The system requires completion of test production and quality verification as preliminary actions before permitting the main production process to start. The permission determination section checks whether test production has been successfully completed and quality standards met before allowing transition to main production. This preliminary action ensures quality control is maintained while still enabling productive main production to proceed efficiently once prerequisites are satisfied.

AI summary
A production management apparatus of a board production line, which can prevent malfunction of the board production device in a test production process, and appropriately maintain the production environment, including: a permission determination section that, before transition from a test production process, in which the inspection device inspects a regulated number of initial boards produced by the board production device as a target, to a later main production process, determines permission for performing an operation command received by the board production device, based on a detection state and a detection result of an initial board by an inspection device; and a processing management section that controls processing of the operation command in the board production device based on a determination result by the permission determination section, is provided.
