Protective Sheet Fixing Jig for Faster Auto Visual Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for securing protective sheets on stages of auto visual inspection devices, such as using adhesive tapes, are inefficient and time-consuming, leading to increased inspection times and difficulty in setting a consistent replacement cycle due to issues like adhesive tape aging, insufficient fixing, and damage to the sheets.
Innovation Solution
A protective sheet fixing jig is introduced, comprising an upper plate, post, bracket, and fixing part, which securely fastens the protective sheet to the stage using fastening members and adjusting screws, allowing for easy installation and replacement without the need for adhesive tapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If adhesive tape is used to secure the protective sheet, then the protective sheet can be fixed to the stage, but the inspection time increases due to frequent replacement and the replacement cycle cannot be standardized
Solution Approach 1:
The patent replaces the adhesive-based mechanical system with a mechanical fastening system. The fixing jig uses screws, clamps, or clips to mechanically secure the protective sheet to the stage, eliminating the need for adhesive tape. This mechanical substitution provides reliable and standardized fixation that can be quickly adjusted and replaced, thereby reducing inspection time while maintaining fixing reliability.
2Ease of operation
If adhesive tape is used to fix the protective sheet, then the sheet can be secured, but replacement becomes time-consuming when the tape ages or needs repositioning
Solution Approach 1:
The patent segments the fixation system into modular components: a removable fixing jig, detachable fastening elements (screws, clamps, or clips), and a standardized mounting interface. This segmentation allows the protective sheet to be quickly released and replaced by simply removing the fixing jig components without damaging the sheet or stage, significantly reducing maintenance time while improving replacement ease.
3Adaptability or versatility
If adhesive tape is used to secure the protective sheet, then fixation can be achieved, but it is difficult to set a consistent replacement cycle due to diverse replacement causes
Solution Approach 1:
The patent designs a universal fixing jig that can accommodate different protective sheet sizes, shapes, and material types through adjustable fastening mechanisms and interchangeable components. This universal design allows the same fixation system to be used across various applications and inspection stages, providing flexibility in setting replacement cycles while avoiding the need for multiple specialized fixation systems, thereby reducing overall device complexity.

AI summary
A protective sheet fixing jig fixes the protective sheet placed on the stage. The protective sheet fixing jig includes: an upper plate pressing the protective sheet on the stage to tightly fix the protective sheet to the stage; a post disposed at a side of the stage and connected with the upper plate; a bracket facing the upper plate and connected with the post; and a fixing part fastened to the bracket to press a lower surface of the stage.
