Stamp Face Forming Device Support Unit Torque Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stamp face forming devices face issues with maintaining a consistent pressing force, leading to uneven stamp face formation, particularly near the edges, due to torque-induced tilting of the stamp material holder, which affects the conveyance speed and quality of the stamp face.
Innovation Solution
A stamp face forming device with a support unit that cancels out torque generated by the pressing force, ensuring the stamp material holder remains aligned with the conveyance path, utilizing a thermal head and conveyance mechanism to form ink-permeable and non-ink-permeable areas on the stamp material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the stamp face forming unit is pressed at a preset force onto the stamp material while moving the stamp face forming unit relative to the stamp material, then the stamp face can be formed, but the pressing force becomes inconsistent near the edges causing uneven stamp face formation
Solution Approach 1:
The support unit functions as a counterbalancing mechanism that applies an opposing force to compensate for the torque generated during pressing. When the stamp face forming unit presses onto the stamp material, it generates a torque that would cause the stamp material holder to tilt. The support unit detects this torque and applies a counteracting force through the conveyance path to maintain the holder's alignment, ensuring consistent pressing force across the entire stamp face including edge areas.
2Manufacturing precision
If the stamp material holder is moved relative to the stamp face forming unit along a conveyance path, then the stamp face can be formed across the surface, but torque is generated causing the holder to tilt with respect to the conveyance path
Solution Approach 1:
The support unit acts as an intermediary mechanism between the stamp material holder and the conveyance system. Rather than directly modifying the holder or the conveyance path, the support unit mediates the interaction by detecting torque through the conveyance path and applying compensating forces. This intermediary approach maintains alignment precision while avoiding complex modifications to the primary holder or conveyance structures.
3Reliability
If the stamp material holder tilts with respect to the conveyance path, then the pressing state changes, but the stamp face cannot be suitably formed
Solution Approach 1:
The support unit implements a feedback mechanism where the torque generated during pressing is continuously detected through the conveyance path. This torque information serves as feedback that triggers compensating actions by the support unit. The system monitors the pressing state via torque detection and automatically adjusts to maintain proper alignment, ensuring reliable stamp face formation without requiring manual intervention to stabilize the pressing state.

Function Achieved in This Case
This solution ensures consistent and high-quality stamp face formation across the entire surface by maintaining a stable pressing force and preventing tilting of the stamp material holder, thereby improving the precision and uniformity of the stamp face.
Implementation Method 1
A heat-generating unit in the stamp face forming unit is selectively heated and a portion that is not ink-permeable and a portion that is ink-permeable are formed in the stamp material

AI summary
A stamp face forming device, including: a stamp face forming unit that forms a stamp face on a stamp material while pressing the stamp material held on a stamp material holder; a conveying unit that causes the stamp material holder to move relative to the stamp face forming unit; and a support unit that supports the stamp material holder in order to prevent tilting of the stamp material holder with respect to a conveyance path for the stamp material holder of the stamp face forming unit, at least when the stamp face is being formed.
