Linear-Motor Lamination Stage for Fewer Workpiece Transfers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamination devices require multiple transfers of workpieces between mechanisms, leading to increased lamination time and inefficiency.
Innovation Solution
A lamination device with multiple supply mechanisms and a movement mechanism using linear motors, where the control unit corrects the relative position of workpieces on a lamination stage before lamination, allowing for direct transfer from supply mechanisms to the movement mechanism, thereby reducing the number of transfer processes and shortening lamination time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If multiple transfer processes are used between conveyance mechanism, transfer mechanism, and lamination mechanism, then workpiece handling is achieved, but lamination time increases
Solution Approach 1:
The patent merges the conveyance mechanism and lamination mechanism into a single integrated lamination mechanism that performs both conveyance and lamination functions. The mover includes both a conveyance stage and a lamination stage, eliminating the need for separate transfer mechanisms and reducing the number of transfer processes while maintaining workpiece handling capability
Solution Approach 2:
The lamination mechanism is designed with multi-functionality, where the mover can perform both conveyance operations and lamination operations. The holding member can hold workpieces during conveyance and then transfer them to the lamination stage for lamination, allowing a single mechanism to fulfill multiple functions that previously required separate mechanisms
2Manufacturing precision
If relative position correction is performed on workpiece, then lamination precision is improved, but positioning time increases
Solution Approach 1:
The control unit performs relative position correction in advance before the lamination process. The holding member holds the workpiece at a supply position, and the control unit corrects the relative position between the workpiece and lamination stage before the mover transfers the workpiece to the lamination stage, ensuring precision is achieved beforehand
Solution Approach 2:
The patent replaces complex mechanical positioning systems with a control-based approach. The control unit calculates and corrects relative positions using control signals, substituting mechanical adjustment mechanisms with electronic control that can rapidly adjust positions without physical mechanical interventions

AI summary
A lamination device that laminates a plurality of types of workpieces includes a plurality of supply mechanisms that supply a workpiece to each of a plurality of supply positions, a movement mechanism including a stator of a linear motor having a predetermined traveling track and a mover of a linear motor that is movable between a plurality of the supply positions along a traveling track, and a control unit that controls at least the mover. The mover includes a lamination stage for laminating the workpiece. The control unit corrects a relative position of the workpiece supplied to the supply positions with respect to the lamination stage, laminates the workpiece whose relative position is corrected on the lamination stage, and controls the mover so as to move to a next one of the supply positions after lamination of the workpiece.
