Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and high cost of 3-axis control systems in marking machines limit their development and adoption, despite significant demand, due to the need for multiple motor axes and electronic control means for precise movement along X, Y, and D axes.
Innovation Solution
A marking device with automatic control means that incorporates electronic means for controlling motor movements along X, Y, and D axes, utilizing a power supply bypass system with switching relays to control the D axis motor using Y axis motor drivers, and includes a blocking mechanism such as a permanent magnet or holding current to manage the marking head's position, allowing for reduced cost and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 3-axis control means are implemented to enable marking of circular parts, then marking versatility is improved, but device complexity and cost increase
Solution Approach 1:
The Y-axis motor driver is designed to perform dual functions: controlling the Y-axis movement and controlling the D-axis rotation. By making the Y-axis driver universal, the system achieves 3-axis functionality without adding a dedicated D-axis driver, thus reducing overall system complexity while maintaining marking versatility for both planar and circular parts
Solution Approach 2:
The control functions for the Y-axis and D-axis are merged into a single motor driver unit. The switching relay system allows the same driver circuitry to be dynamically assigned to control either the Y-axis linear movement or the D-axis rotation, combining multiple control functions into one integrated unit
2Manufacturing precision
If multiple motor axes with dedicated control means are used, then marking precision is improved, but production and sales costs increase
Solution Approach 1:
The Y-axis motor driver is designed as a universal controller that can precisely control both Y-axis linear movement and D-axis rotation. This multi-functional driver eliminates the need for expensive dedicated D-axis driver hardware while maintaining the precision required for accurate marking on both flat and circular surfaces
Solution Approach 2:
The control architecture uses the existing Y-axis driver circuitry and control logic as a template for D-axis control. By reusing the proven Y-axis driver design for the D-axis through the switching relay system, the system achieves precise control without incurring additional development and manufacturing costs for separate control circuits
3Measurement precision
If a dedicated D-axis motor driver is implemented, then control accuracy for circular parts is improved, but electronic control complexity increases
Solution Approach 1:
The Y-axis motor driver is configured to universally control both Y-axis and D-axis movements. The switching relay system enables the same driver to accurately control different axes at different times, maintaining control accuracy for circular parts without requiring a separate dedicated D-axis driver that would increase electronic control complexity
Solution Approach 2:
The control system dynamically switches the Y-axis driver's function between controlling Y-axis linear movement and D-axis rotation based on the marking operation requirements. This dynamic reconfiguration allows a single driver to adapt to different control needs, maintaining accuracy while avoiding the complexity of multiple static control circuits
