Production Management Device Dynamic Job Data Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In family production for multiple pattern boards, unnecessary product types can lead to wasted unit boards and increased production costs due to time-consuming job data regeneration and skipped mounting processes.
Innovation Solution
A production management device that identifies unit board types and prioritizes mounting processes based on error rates and production state, using a shared control program to dynamically adjust production plans and avoid wasting unit boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If job data is regenerated when production of a certain product type becomes unnecessary or when a mounting process becomes unable to be executed, then the production plan can be adjusted, but it takes time to generate job data and unit boards are wasted, thereby increasing production cost
Solution Approach 1:
The system dynamically switches between different job data sets based on real-time production status. The control device selects between a first job data set (when mounting processes can be executed) and a second job data set (when production of certain product types becomes unnecessary), allowing the production plan to adapt without time-consuming regeneration of job data.
Solution Approach 2:
Multiple job data sets are prepared in advance for different production scenarios. The control device pre-stores alternative job data that can be immediately activated when production conditions change, eliminating the need for on-the-fly job data generation and avoiding production delays.
2Ease of manufacture
If unit boards are skipped when a mounting process becomes unable to be executed, then the mounting process can be avoided, but unit boards are wasted, thereby increasing production cost
Solution Approach 1:
The system changes the operational parameters by switching between different job data sets that specify different mounting processes. When certain mounting processes cannot be executed, the control device selects alternative job data that adjusts the mounting parameters to accommodate the available processes, thereby utilizing all unit boards without waste.
Solution Approach 2:
The control device monitors the execution status of mounting processes and uses this feedback to select appropriate job data sets. When production status indicates that certain product types are unnecessary or mounting processes fail, the system responds by switching to alternative job data that prevents unit board waste.
3Productivity
If multiple types of mounting processes are executed for each unit board in family production, then multiple types of board products can be produced, but the system complexity increases
Solution Approach 1:
The control device is designed with multi-functionality to handle multiple types of mounting processes. By implementing a unified control mechanism that can select and execute different job data sets, the system achieves high productivity through family production while managing complexity through a single versatile control unit rather than multiple specialized systems.

AI summary
An object of the present invention is to provide a production management device capable of responding to a production request by making it possible to switch execution of a mounting process on multiple unit boards, thereby preventing an increase in production cost. Production management device 60 includes data management section 61 having multiple correspondence data (BOM1, BOM2, BOM3) in which component types are linked to each product type (U1, U2, U3) of board product with reference codes, and process setting section 62 for selecting, when circuit board 90 is carried into component mounting machine 1 in a family production, a product type for each of multiple unit boards 91 based on identification information (S36) and sets the type of mounting process to be executed for each of multiple unit boards 91 by selecting correspondence data for the selected product type (S37).
