Linear-Motor Lamination Stage for Continuous Workpiece Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamination devices experience delays in the lamination process due to the time required for conveying workpieces from the conveyance mechanism to the lamination mechanism, leading to inefficiencies in shortening the overall lamination time.
Innovation Solution
A lamination device equipped with multiple supply mechanisms and a movement mechanism using linear motors, where the mover holds and corrects the relative position of workpieces with respect to the lamination stage while moving between supply positions, allowing for simultaneous lamination and position correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the transfer mechanism conveys workpiece from conveyance mechanism to lamination mechanism, then workpiece can be transferred to lamination position, but lamination time is extended due to conveyance time
Solution Approach 1:
The mover performs lamination action continuously during its movement between supply positions rather than stopping at each position. The control unit controls the mover to laminate workpiece on the lamination stage while the mover moves from one supply position to the next supply position, eliminating idle time and making the lamination process continuous throughout the movement cycle.
Solution Approach 2:
The holding unit holds the workpiece in advance at the supply position before movement begins. The control unit is configured to correct relative position of workpiece with respect to lamination stage before the mover starts moving, so that lamination can immediately begin during movement without any positioning delays during the lamination process.
2Productivity
If multiple supply mechanisms are used to supply workpiece to multiple supply positions, then workpiece supply efficiency is improved, but device complexity increases
Solution Approach 1:
The single mover is designed to perform multiple functions: it visits multiple supply positions to collect different workpieces, transports them to the lamination stage, and performs lamination. This multi-functional design eliminates the need for separate mechanisms for each supply position while maintaining high productivity through sequential operations.
Solution Approach 2:
The lamination process is segmented into discrete steps corresponding to different supply positions. The mover sequentially visits each supply position, holds the workpiece, and performs lamination at different stages of its movement cycle. This segmentation allows efficient use of a single mover across multiple positions without requiring simultaneous complex mechanisms at each position.

Function Achieved in This Case
This approach significantly reduces the lamination time by enabling continuous lamination as the mover moves between positions, improving efficiency and simplifying the operation of supply mechanisms.

AI summary
A lamination device that laminates a plurality of types of workpieces includes supply mechanisms that supply the workpiece to each 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 controller that controls at least the mover. The mover includes a holding unit that holds the workpiece supplied to the supply positions, and a lamination stage for lamination the workpiece. The controller corrects a relative position of the workpiece with respect to the lamination stage and controls the mover to laminate the workpiece whose relative position is corrected on the lamination stage while the holding unit holds the workpiece supplied to the supply positions and moves to and stops at a next one of the supply positions.
