Laser Marking Trigger Timing for Flexible Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser marking apparatuses require trial and error for skilled users to adjust the timing of the trigger signal for precise marking on flexible workpieces with alignment marks, leading to poor user convenience.
Innovation Solution
A laser marking apparatus that includes a setting section to display a setting-assist image showing alignment marks and offset amounts, allowing users to easily set the offset amount for precise marking, and an interface section to receive trigger signals and control the marking process based on the determined movement amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the trigger signal timing is adjusted manually for precise marking, then the marking precision is improved, but the ease of operation deteriorates due to requiring trial and error even for skilled users
Solution Approach 1:
The system automatically calculates the optimal trigger signal timing by monitoring the actual movement amount of the flexible workpiece between the alignment mark detection and the marking position, and uses this feedback to adjust the trigger signal timing without requiring manual trial and error
Solution Approach 2:
The system performs self-adjustment of the trigger signal timing by automatically calculating the movement amount and determining the optimal timing, eliminating the need for user intervention and manual adjustment
2Productivity
If the trigger signal is sent immediately after alignment mark detection to maximize speed, then the productivity is improved, but the marking precision deteriorates due to inability to account for workpiece movement
Solution Approach 1:
The system pre-calculates the optimal trigger signal timing by monitoring the workpiece movement amount and storing this information for future marking operations, allowing the trigger signal to be sent at the precisely calculated moment rather than immediately or through trial and error

AI summary
To improve convenience in use of a laser marking apparatus that performs marking on a workpiece to which an alignment mark is affixed. The laser marking apparatus includes a setting section, a second IF section, a movement amount monitoring section, and a marking control section, and the setting section causes a display section to display a setting-assist image, which visually indicates the alignment mark on the flexible workpiece and a trigger delay, and receives a user input for setting the trigger delay in a state where the setting-assist image is displayed.
