Solution Overview
Problem
The existing shot processing technologies face challenges in efficiently inspecting the inner walls of holes in workpieces, leading to increased processing time due to limited visibility, which delays subsequent processing steps and prolongs the overall processing time for multiple workpieces.
Innovation Solution
A shot processing apparatus and method utilizing a rotary table with conveyors and an inspection area that allows for simultaneous processing and inspection of workpieces, enabling efficient conveyance and inspection of workpieces without changing their orientation, thereby reducing overall processing time by integrating processing and inspection steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an inspection step is performed after each workpiece processing step to ensure quality, then the quality of the workpiece is secured, but the processing time increases and the start of the next workpiece processing step is delayed
Solution Approach 1:
The inspection step is moved to occur before the shot peening processing step rather than after it. Workpieces are inspected for hole quality prior to processing, allowing defective workpieces to be identified and removed from the production flow before they consume processing time. This preliminary inspection approach ensures quality control while maintaining continuous processing of good workpieces.
2Device complexity
If the viewable direction of the inner wall of the hole is limited during inspection, then the inspection setup is simple, but the inspection time increases
Solution Approach 1:
The inspection system utilizes optical fibers that can transmit light along curved paths, allowing inspection of the hole inner wall from multiple angles and directions. The optical fibers are inserted into the hole and can reach the bottom and sides, providing comprehensive viewing capability without requiring complex mechanical positioning systems or changing the workpiece orientation.
3Device complexity
If a linear conveyance path is used for workpieces, then the apparatus structure is simple, but the entire processing time for multiple workpieces increases
Solution Approach 1:
The apparatus employs a rotary table that rotates to dynamically change the positions of multiple workpieces. As the rotary table rotates, different workpieces sequentially pass through the inspection area, processing chamber, and discharge area. This dynamic positioning allows continuous processing where one workpiece is being processed while another is being inspected, eliminating idle time and improving throughput.
Solution Approach 2:
The system maintains continuous useful action by overlapping the inspection step with the processing step. While one workpiece undergoes shot peening processing in the processing chamber, another workpiece simultaneously undergoes inspection at the inspection area. This parallel execution of inspection and processing eliminates waiting time and ensures continuous productivity.
