Rotor Magnet Insertion Alignment for Smooth Slot Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotor assembling apparatuses face difficulties in efficiently and smoothly inserting multiple permanent magnets into slots of a rotor core, especially when the magnets are not aligned properly, leading to interference with the rotor core and reduced productivity.
Innovation Solution
A magnet insertion device comprising a magazine, a pusher, an aligning member, and an insertion mechanism, which aligns and collectively inserts sets of magnets into magnet housing holes of a rotor core, ensuring precise alignment and smooth insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple permanent magnets are collectively held and inserted into a slot, then productivity is improved, but insertion smoothness deteriorates due to misalignment interference
Solution Approach 1:
The patent applies preliminary action by providing an alignment mechanism that aligns multiple permanent magnets in the magnet holding portion before they are inserted into the slot. This pre-alignment ensures that when magnets are collectively inserted, they are properly positioned and do not interfere with the rotor core, thus maintaining both high productivity and smooth insertion
2Ease of operation
If magnets are aligned in advance before insertion, then insertion smoothness is improved, but device complexity increases due to additional alignment mechanism
Solution Approach 1:
The alignment mechanism is integrated into the magnet holding portion structure, making it a multi-functional component that both holds magnets and aligns them. This integration reduces overall device complexity while ensuring proper magnet alignment for smooth insertion
3Device complexity
If magnets are not aligned properly, then device complexity is reduced, but manufacturing precision deteriorates due to misalignment
Solution Approach 1:
The magnet holding portion structure itself provides the alignment function through its geometric design, eliminating the need for separate complex alignment devices. The structure automatically aligns magnets during the holding process, ensuring manufacturing precision while keeping the device simple

AI summary
A magnet insertion device includes a magazine, a pusher, an aligning member, and an insertion mechanism. The magazine includes a housing body and an extruding portion configured to move magnets in the housing body in a stacking direction to sequentially extrude the sets of the magnets from the housing body. The pusher is configured to move each set of the magnets by collectively pushing the set of the magnets. The aligning member is configured to align the magnets in each set by coming into contact with opposite sides in the arrangement direction of the set of the magnets when the magnets are pushed and moved by the pusher. The insertion mechanism is configured to collectively grip each set of aligned magnets and insert the magnets into a magnet housing hole.
