Appearance Inspection Route Timing for Pre-Arrival Imaging Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing appearance inspection systems face inefficiencies in imaging multiple target positions due to the need to change imaging conditions after arriving at each position, leading to prolonged inspection times.
Innovation Solution
An appearance inspection system that sets a route for the imaging device to move between multiple positions, allowing the imaging condition change process to start earlier than the device's arrival at the next position, ensuring instantaneous imaging when the device arrives, and includes an estimation part to calculate the necessary time for condition changes based on pre-decided correlations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the imaging condition is changed after arrival at the imaging position, then the imaging position can be optimized for each inspection target position, but the inspection time is prolonged due to temporary stop of the imaging device operation
Solution Approach 1:
The control part starts the process of changing the imaging condition before the imaging device arrives at the target imaging position. By initiating the condition change process in advance during the movement from the first imaging position to the second imaging position, the system ensures that the imaging condition is ready when needed, eliminating waiting time and maintaining continuous operation.
2Measurement precision
If the imaging condition is changed for each inspection target position, then the imaging quality can be optimized, but the operation of the imaging device must be temporarily stopped
Solution Approach 1:
The control part initiates the imaging condition change process before the imaging device stops at the target position. This preliminary action allows the condition change to occur during movement, ensuring that when the device arrives at the position, the optimized imaging condition is already in place, maintaining both quality and productivity.
Solution Approach 2:
The system maintains continuous operation of the imaging device by overlapping the condition change process with the movement between positions. The imaging device does not need to stop temporarily because the condition change is initiated in advance and completes during or before the arrival at the target position, ensuring uninterrupted inspection workflow.
3Loss of time
If the route is set to allow early start of condition change process, then the inspection time is shortened, but the coordination between movement and condition change becomes more complex
Solution Approach 1:
The control part monitors the movement state of the imaging device and uses this feedback information to determine the optimal timing for starting the condition change process. By receiving feedback on position and movement status, the control system can dynamically adjust when to initiate condition changes, ensuring synchronization without excessive complexity.

AI summary
An appearance inspection system includes a setting part, a movement mechanism, and a control part. The setting part sets a route passing through a plurality of imaging positions in order. The setting part sets the route so that a first time necessary for the movement mechanism to move an imaging device from a first imaging position to a second imaging position among the plurality of imaging positions is longer than a second time necessary for a process of changing a first imaging condition corresponding to the first imaging position to a second imaging condition corresponding to the second imaging position by the control part. The control part starts the process of changing the first imaging condition to the second imaging condition earlier by the second time or more than a scheduled time at which the imaging device arrives at the second imaging position.
