Backup Pin Accommodation in Component Mounters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing component mounting systems, the type or number of backup pins needed to support different types of printed wiring boards often requires manual adjustment for each job change, leading to inefficient operation.
Innovation Solution
A determination device within a component mounter calculates the optimal number and type of backup pins to be accommodated based on the required number for each job, considering the maximum accommodation capacity, to minimize the frequency of adjustments and operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual replacement of backup pins is performed for each job change, then the correct number and type of backup pins are ensured, but operator intervention time and production downtime increase
Solution Approach 1:
The system performs preliminary calculation of the required backup pin configuration before job execution. The determination device computes the optimal backup pin arrangement in advance based on job data, so that when a job change occurs, the system already has the correct configuration ready, eliminating the need for manual adjustment and reducing downtime while ensuring accuracy.
2Device complexity
If backup pins are accommodated in a fixed accommodation device, then the structure is simple, but the system lacks flexibility when different job types require different numbers of backup pins
Solution Approach 1:
The system introduces dynamic adaptability through automated determination. The accommodation device structure remains relatively simple, but it becomes dynamically adaptable through the determination device that calculates and directs the appropriate backup pin configuration for each job type, allowing the system to flexibly respond to different job requirements without complex manual reconfiguration.
3Adaptability or versatility
If the number of backup pins is increased to accommodate all possible job types, then all jobs can be supported, but the accommodation device size and complexity increase
Solution Approach 1:
The determination device serves as a universal control mechanism that enables a single accommodation device to handle multiple job types. Instead of increasing the physical size of the accommodation device to accommodate all possible backup pin configurations simultaneously, the universal determination system calculates and directs the appropriate configuration for each specific job, allowing one device to perform multiple functions.

AI summary
There is provided a technology capable of efficiently accommodating backup pins when different types of jobs are produced in order. A determination device determines an accommodation plan for accommodating the backup pins in the backup pin accommodation section. The determination device includes: a job acquisition section configured to acquire a job for defining a type of the board on which a component is mounted and a required number of backup pins required to support the type of board; a maximum accommodation number acquisition section configured to acquire a maximum accommodation number of backup pins accommodatable in the backup pin accommodation section; and an accommodation plan determination section configured to determine the number of backup pins accommodated in the backup pin accommodation section before start of production of each of multiple jobs based on the required number of backup pins required in each of the multiple jobs and the maximum accommodation number of backup pins accommodatable in the backup pin accommodation section when a production order of the multiple acquired jobs is determ ined
