1Productivity
If a conventional high-frequency induction heating member is used for glass plate processing, then the processing can be performed continuously, but misalignment and non-uniform pressure application occur leading to processing defects
Solution Approach 1:
The heating member is designed with flexible or adjustable components that can dynamically adapt to the glass plate surface, maintaining uniform contact pressure during continuous movement. This includes using spring-loaded mechanisms or adjustable positioning systems that compensate for variations in glass plate position and thickness, ensuring consistent processing quality throughout continuous operation.
Solution Approach 2:
The system incorporates sensors and control mechanisms that continuously monitor the position and contact pressure of the heating member against the glass plate. Real-time feedback allows the system to automatically adjust the heating member's position and pressure to maintain uniform processing, preventing misalignment and processing defects while sustaining continuous operation.
2Productivity
If the heating rod performs heat chamfering along a preset processing path, then the processing efficiency is improved, but the heating rod may be tilted or positioned deviated from the preset point causing processing defects
Solution Approach 1:
The system performs preliminary positioning and alignment of the heating member before actual processing begins. This includes pre-calibration of the processing path, preliminary contact testing to establish proper pressure and position, and pre-adjustment of the heating member orientation to ensure it is correctly aligned with the glass plate surface before high-speed processing commences.
Solution Approach 2:
The patent replaces purely mechanical positioning systems with a combination of mechanical structures and field-based control systems. This includes using electromagnetic fields, optical sensors, or other non-mechanical sensing and control mechanisms to maintain precise positioning of the heating member, reducing mechanical wear and improving position accuracy during efficient continuous processing.
3Productivity
If thermal deformation occurs in the heating rod, then the cross-sectional shape becomes non-uniform causing center point deviation, but the processing continues without correction leading to corner formation defects
Solution Approach 1:
The system implements periodic cooling intervals, position recalibration, and heating member realignment during continuous processing. This periodic maintenance of optimal conditions prevents cumulative thermal deformation effects, ensuring that the heating member maintains its correct geometry and position throughout extended operation, thereby producing uniform corner results while sustaining high productivity.
Solution Approach 2:
The system dynamically adjusts processing parameters such as heating power, processing speed, and cooling rates to compensate for thermal deformation. By changing these parameters in response to detected thermal conditions, the system maintains consistent processing quality and corner uniformity even during continuous operation where thermal effects would otherwise accumulate and degrade precision.
