Solution Overview
Problem
Existing sandblasting systems face challenges in ensuring precise and repeatable alignment and orientation of objects during loading and unloading, leading to inefficiencies and potential faults in the processing operation.
Innovation Solution
A receiving device with individually or collectively driven turntables, equipped with a friction wheel and cam disk system, allows for precise alignment and return to a consistent position using a stop roller and aligner, enabling reliable and noise-reduced operation, and allowing for both manual and robotic loading.

Engineering Contradiction Analysis
1Productivity
If a rotary table with receiving parts is used for sandblasting processing, then processing efficiency is improved through continuous rotation and multiple receiving parts, but alignment precision and repeatability of loading/unloading positions deteriorate
Solution Approach 1:
The cam disc is pre-configured with specific curve profiles that automatically guide the stop roller to the correct position during rotation. This preliminary geometric configuration ensures that receiving parts return to their original loading positions without requiring active control during operation, thus maintaining alignment precision while enabling continuous processing
Solution Approach 2:
The friction wheel with stop roller automatically aligns receiving parts with the loading position through self-contained mechanical feedback. The stop roller follows the cam disc profile and autonomously returns components to their starting position, eliminating the need for external alignment systems and maintaining precision throughout continuous rotation
2Manufacturing precision
If friction wheels and stop rollers are added to ensure precise alignment, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The alignment function is merged into the existing rotary table structure by integrating the cam disc as a component of the rotary table assembly and the stop roller as part of the receiving part mechanism. This combination eliminates the need for separate alignment systems, maintaining simplicity while achieving precise positioning
Solution Approach 2:
The cam disc serves as an intermediary element between the rotary table's rotation mechanism and the receiving parts. It translates rotational motion into precise positioning through its geometric profile, mediating between the drive system and the receiving parts without requiring complex control mechanisms
