Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting devices for liquid crystal panel substrates, components loaded on the substrate are prone to dropping during transfer from the loading to crimping operation due to shocks during substrate movement.
Innovation Solution
A component mounting device with dual substrate transport units and crimping units positioned on either side of the loading unit, allowing for stable substrate transfer and crimping without intermediate movement, utilizing position recognition and support stages to maintain component alignment and prevent drops.

Engineering Contradiction Analysis
1Productivity
If substrate transfer is performed by substrate transfer unit during operation process, then productivity is improved by continuous delivery, but component may be dropped by shock during transfer
Solution Approach 1:
The substrate placement stage serves as an intermediary platform between the substrate transfer unit and the component loading operation unit. The substrate is placed on this stage and remains stationary during the component loading process, isolating the component from shocks during substrate transfer. This mediator structure allows continuous substrate delivery while preventing component drop.
2Productivity
If substrate is moved during component loading operation, then productivity is improved by continuous processing, but manufacturing precision deteriorates due to component position instability
Solution Approach 1:
The manufacturing process is segmented into distinct stages: substrate transfer to placement stage, component loading on stationary substrate, and then substrate transfer to crimping unit. By separating the substrate transfer operations from the component loading operation and using the placement stage as a stationary workspace, the system achieves continuous processing while maintaining component position stability.
3Productivity
If component loading operation unit loads component on moving substrate, then productivity is improved by dynamic operation, but manufacturing precision deteriorates due to alignment difficulty
Solution Approach 1:
The substrate is preliminarily positioned and fixed on the substrate placement stage before the component loading operation begins. This preliminary positioning action creates a stable reference frame for precise component alignment. The substrate remains in this predetermined position throughout the component loading process, ensuring accurate alignment while maintaining dynamic operational efficiency.

AI summary
While a substrate is placed on a substrate placement stage provided in a central substrate transfer unit, the substrate is transferred to a component loading operation unit, after operation for loading a component on the substrate has been performed by the component loading operation unit, the central substrate transfer unit is moved to the side of a first component crimping operation unit to thereby transfer the substrate that remains placed on the substrate placement stage to the first component crimping operation unit, and the component is crimped to the substrate by the first component crimping operation unit.
