Sliding Device Dust-Proof Cover for Miniature Linear Motor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miniature sliding devices with onboard moving magnet linear motors face challenges in protecting against external environments due to their downsized construction, which makes them prone to adverse effects from foreign matter like dirt and dust, while maintaining high precision, speed, and reliability in operation.
Innovation Solution
A sliding device with an overall flat configuration featuring a dust-proof cover that can be easily mounted, incorporating a moving-magnet linear motor with a field magnet array and armature assembly, and end blocks with elastic cushioning portions to secure the cover in place, ensuring the device is compact and protected from external environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the sliding device is downsized or miniaturized to reduce height and improve compactness, then the device becomes more compact and energy efficient, but the device becomes more prone to adverse effects from foreign matter such as dirt and dust
Solution Approach 1:
A dust-proof cover is introduced to envelop the sliding device, protecting it from foreign matter. The cover acts as a protective shell that maintains the miniaturized compact form while preventing harmful factors from affecting the internal components.
2Object-affected harmful factors
If a dust-proof covering is added to protect the sliding device from external environments, then protection against foreign matter is improved, but the device complexity and mounting difficulty increase
Solution Approach 1:
The dust-proof cover is divided into multiple segments: a ceiling part with an opening, a peripheral part extending downward, and end blocks at opposite ends. This segmentation allows the cover to be mounted independently on each end block, simplifying the overall mounting process while maintaining comprehensive protection.
Solution Approach 2:
The cover design allows for easy self-mounting through elastic cushioning portions that enable snap-fit attachment to the end blocks. The opening in the ceiling part is positioned to automatically align with the table during mounting, eliminating the need for complex alignment procedures.
3Volume of moving object
If the sliding device is miniaturized to meet stringent height specifications, then compactness is improved, but the propulsion force is reduced making the device more vulnerable to external环境影响
Solution Approach 1:
The dust-proof cover creates a sealed environment that protects the reduced-propulsion miniaturized device from external forces caused by foreign matter. This allows the device to maintain small dimensions while the cover compensates for the reduced ability to resist external environmental factors.

Function Achieved in This Case
The solution provides a high level of dust-proofing and safety for the sliding device, maintaining high precision and reliability even in compact construction, with the dust-proof cover allowing easy mounting and demounting, and ensuring the device operates in a clean environment.
Implementation Method 1
a moving-magnet linear motor built in between the table and the bed to extend lengthwise between the linear motion guide units and composed of a field magnet array and an armature assembly lying in opposition to the field magnet array
Implementation Method 2
the butting surfaces of the end blocks having elastically deformable cushioning portions

AI summary
A covering is easily mounted and/or demounted to envelop an overall sliding device with onboard moving-magnet linear motor. The covering helps improved propulsion, high velocity and response of a table even with small in dimension, compact in construction. End blocks are installed in opposite ends of a bed and a linear motor is placed between the bed and the table. The end blocks are made in solid bodies which are tightened to the bed together with a coil board. The end blocks have butting surfaces which can come into abutment against the ends of the table to protect the table from getting out of the bed. The end blocks have locking recesses which mate with locking jaws on the covering to fasten the covering to the end blocks.
