Laminated Core Separation Jig Radial Force Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for separating a laminated core into individual core pieces are inefficient due to the narrow intervals between tooth portions, making it difficult to wind wires and requiring significant time and effort, especially since the core pieces are temporarily connected at end portions of the yoke portions.
Innovation Solution
A separation jig and apparatus that uses movable separation members arranged in a circumferential direction, actuated to apply a radial outward force to the laminated core, allowing for simultaneous and uniform division of the core pieces by guiding and restricting movement to prevent wobbling and ensure uniform force application.

Engineering Contradiction Analysis
1Productivity
If manual separation of core pieces is performed, then the laminated core can be divided into individual core pieces, but the process requires significant time and effort due to narrow intervals between tooth portions
Solution Approach 1:
The separation apparatus divides the laminated core into multiple core pieces using multiple separation members arranged circumferentially. Each separation member targets a specific gap between tooth portions, enabling simultaneous separation of multiple core pieces rather than manual one-by-one division, thus dramatically improving productivity and reducing time loss.
Solution Approach 2:
The separation members are designed to be movable in the radial direction of the laminated core. When actuated, they move outward to apply separation force to the core pieces. This dynamic movement allows the system to transition from a static configuration to an active separation process, enabling rapid and controlled division of the laminated core without manual intervention.
2Productivity
If force is applied to separate core pieces, then the core can be divided, but uneven force distribution may cause peeling off of workpieces
Solution Approach 1:
Each separation member is independently positioned and actuated to apply force locally at specific separation points between core pieces. This localized force application ensures that each core piece is separated uniformly without excessive force on any single point, preventing peeling or damage to the workpieces while maintaining high separation efficiency.
Solution Approach 2:
The separation members are arranged symmetrically in the circumferential direction and move uniformly in the radial direction. This homogeneous arrangement ensures that force is distributed evenly across all core pieces during separation, maintaining consistent stress distribution and preventing localized peeling or deformation of the workpieces.
3Productivity
If multiple separation members are used to divide core pieces simultaneously, then separation speed improves, but device complexity increases
Solution Approach 1:
All separation members share the same structural design and movement mechanism, allowing them to be controlled by a single actuator system. This universal design enables multiple separation members to function together as a coordinated system, achieving high throughput without proportionally increasing device complexity, as each component serves the same purpose with identical structure.

AI summary
A separation apparatus for a laminated core is configured to separate an annular laminated core, which includes a plurality of core pieces each of which includes a yoke portion and a tooth portion extending from the yoke portion in a direction intersecting the yoke portion and is integrated by the temporary connection of the adjacent core pieces at end portions of the yoke portions, into the respective core pieces. The separation apparatus includes a plurality of separation members that are movable in a radial direction of the laminated core and are disposed so as to be arranged in a circumferential direction of the laminated core, and an actuator that is configured to apply an outward force in the radial direction to the laminated core through the respective separation members by moving the respective separation members outward in the radial direction.
