Scan Mirror Assembly Jigs for Precise Galvo Mirror Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the manufacturing process of display devices using lasers, errors in the scanner's position can lead to a deterioration in the quality of the display device due to deviations in the final pattern formation from the designed position.
Innovation Solution
An assembly device for a scan mirror is developed, comprising an encoder, a coil, a cylindrical third part with a reference diameter, a mount, and a Galvo mirror. The assembly device includes a first assembly jig with a groove for the Galvo mirror, a second assembly jig with a groove for the third part, and an upper fixing guide to securely assemble the Galvo mirror to the mount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the Galvo mirror is assembled to the mount without a standardized assembly device, then the assembly process becomes complex and time-consuming, but the manufacturing precision and positioning accuracy deteriorate
Solution Approach 1:
The patent introduces assembly jigs as intermediary tools that mediate between the Galvo mirror and the mount. These jigs provide standardized interfaces and guiding features that ensure precise positioning during assembly, eliminating the need for complex manual alignment procedures while maintaining high positioning accuracy.
Solution Approach 2:
The patent employs parameter changes by designing the assembly jigs with specific geometric parameters (groove dimensions, positioning feature locations) that correspond to the reference diameter of the third part. By standardizing these parameters, the assembly process achieves consistent precision without requiring complex adjustment procedures.
2Productivity
If a standardized reference diameter is used for the third part, then the assembly process becomes simpler and faster, but the adaptability to different assembly configurations is reduced
Solution Approach 1:
The patent achieves universality by designing the assembly jigs with standardized interfaces that can accommodate multiple assembly configurations. The jigs incorporate universal positioning features and adjustable elements that allow them to work with different Galvo mirror and mount combinations while maintaining the standardized reference diameter approach, thus preserving both speed and flexibility.
3Manufacturing precision
If the assembly device includes multiple jigs and fixing guides, then the assembly accuracy is improved, but the device complexity and cost increase
Solution Approach 1:
The patent applies segmentation by dividing the assembly system into distinct functional components: assembly jigs for positioning, upper fixing guides for securing, and support structures for stability. Each segment performs a specific function, allowing for modular design and manufacturing. This segmentation enables the use of simpler, less expensive components that can be produced independently and assembled into the complete system, reducing overall complexity while maintaining high assembly accuracy.

AI summary
An assembly device of a scan mirror is a device for assembling a scan mirror including an encoder, a first part disposed on the encoder and including a coil, a third part disposed on the first part and of a cylindrical shape having a reference diameter that serves as an assembly standard, a mount disposed on the third part, and a Galvo mirror coupled to the mount to receive rotational force of the coil. The assembly device of the scan mirror includes a first assembly jig including a first surface defined with a first groove into which the Galvo mirror is allowed be seated, a second assembly jig including a third surface defined with a second groove into which the third part is allowed be seated and an upper fixing guide disposed on the second assembly jig and fixing the third part together with the second assembly jig.
