Inspection Device Position Replacing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inspection devices require the operator to manually install and position a master gauge for each alignment, leading to potential deviations between master alignment and inspection positions, resulting in decreased accuracy.
Innovation Solution
An inspection device with a chuck to grip and release workpieces, an inspection machine for contact-based inspection, a master table to hold the master gauge, and a position replacing mechanism that moves the chuck and master table integrally, allowing for simultaneous alignment and inspection at the same position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the master gauge and workpiece are positioned separately for master alignment and inspection, then the inspection device can perform both functions, but the position deviation between master alignment and inspection occurs, reducing inspection accuracy
Solution Approach 1:
The patent combines the master alignment function and inspection function into a single inspection position. The master gauge holder and workpiece holder are integrated at the same location, allowing both master alignment and workpiece inspection to be performed at the identical position, thereby eliminating position deviation and ensuring high inspection accuracy while maintaining functional versatility.
2Ease of operation
If the operator manually installs the master gauge for each alignment, then the master gauge can be positioned, but the operation time increases and the process becomes complex
Solution Approach 1:
The patent implements an automatic exchange mechanism where the system itself performs the master gauge installation and positioning without requiring manual operator intervention for each alignment. The automatic master gauge holder exchanges the master gauge automatically, reducing both operation complexity and setup time while maintaining ease of use.
Solution Approach 2:
The system prepares the master gauge in advance and positions it automatically before the inspection process begins. The master gauge is pre-loaded into the automatic master gauge holder, which then automatically positions it at the inspection position, eliminating the need for manual installation during each alignment operation.
3Ease of manufacture
If separate mechanisms are used for master gauge positioning and workpiece inspection, then each function can be optimized independently, but the device complexity increases
Solution Approach 1:
The patent merges the master gauge positioning mechanism and workpiece inspection mechanism into a single integrated system. Both the master gauge holder and workpiece holder share the same inspection position and are controlled by a unified control system, reducing the number of separate mechanisms while maintaining the ability to optimize both functions simultaneously.

AI summary
An inspection device for performing master alignment and inspection at the same position includes a chuck configured to grip and release a workpiece, an inspection machine configured to, by bringing a contactor into contact with a processed portion of the workpiece, inspect the processed portion, a master table configured to hold a master gauge configured to perform master alignment with respect to the inspection machine, and a position replacing mechanism configured to integrally move the chuck and the master table and replace the workpiece gripped by the chuck and the master gauge held by the master table with each other at an inspection position in the inspection machine.
