Substrate Standby Unit for Electronic Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component mounting systems face difficulties in securing correspondence relations between substrates and inspection result data during the feedforwarding process, particularly when substrates are kept on standby, leading to complications and increased equipment costs due to the need for additional ID readout devices on both sides.
Innovation Solution
An electronic component mounting system with a substrate standby unit that stores identification information and updates it during transfer, allowing for secure transmission of substrate identification and inspection results to the component installation device, ensuring accurate correspondence without additional ID readout devices on the lower surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If ID marks are provided only on the front sides of substrates, then the device structure remains simple, but the ID marks cannot be read out when carrying out operations on the back sides
Solution Approach 1:
A substrate standby unit is introduced as an intermediary between the print inspection device and the component installation device. This standby unit temporarily holds substrates and maintains correspondence between substrates and their inspection result data, enabling identification without requiring ID marks on both sides of the substrate.
2Ease of operation
If an ID readout device is added on the lower surface side to read ID marks during back side operations, then identification capability is improved, but device complexity and equipment cost increase
Solution Approach 1:
The substrate standby unit serves as a mediator that eliminates the need for additional ID readout devices. By maintaining substrate data correspondence in the standby unit, the system achieves full identification capability without adding costly equipment.
Solution Approach 2:
The system copies substrate identification information and inspection result data into the substrate standby unit, creating a data replica that maintains correspondence without requiring physical ID mark reading from the substrate itself during all operations.
3Adaptability or versatility
If substrates are kept on standby in a conveying conveyer with space, then operational flexibility is improved, but correspondence relations between substrates and inspection result data are disturbed when substrates are taken out
Solution Approach 1:
The substrate standby unit implements a feedback mechanism that tracks and maintains correspondence between substrates and their inspection result data. When substrates are loaded or unloaded, the system updates the correspondence information, ensuring data integrity is maintained even during flexible operational changes.

AI summary
A substrate standby unit that is capable of keeping only one substrate 4 on standby in a substrate sorting mechanism 40 that moves the substrate 4 from the print inspection device M2 to the component installation device M4, a memory device 60 that stores a substrate ID on the substrate 4 that is on standby in the substrate standby unit, and a substrate ID management unit 46 that updates the substrate ID that is stored in the memory device 60 accompanying the transfer of the substrate 4 from the print inspection device M2 to the substrate standby unit are included. The substrate ID stored in the memory device 60 and the inspection result data associated with this substrate ID and stored in an inspection result data memory unit 45 are transmitted to the component installation device M4.
