Elastic Positioning Mechanisms for Seal Stamping Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seal stamping machines face issues with unstable positioning between plates, leading to dislocation or blurring of stamped patterns, uneven stress on seals resulting in varied shades, and difficulty in accurately overlapping patterns during re-stamping.
Innovation Solution
The seal stamping machine employs elastic positioning mechanisms with positioning holes and reset springs to ensure firm and uniform pressure, using guide sleeves and antiskid pads for stable alignment and even stress distribution, allowing for precise positioning and uniform stamping without limiting the size of the stamping carrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If magnetic mechanisms are used to generate mutual attraction force between plates, then the sealing and stamping function is achieved, but the positioning between plates becomes unstable and the seal is easy to displace
Solution Approach 1:
The patent divides the pressing force application into multiple independent elastic positioning mechanisms (first elastic positioning mechanism, second elastic positioning mechanism, etc.) distributed at different locations. Each mechanism independently provides positioning and pressing force, ensuring stable positioning while achieving the required sealing force. This segmentation resolves the contradiction by distributing the force application points rather than relying on a single magnetic attraction point.
Solution Approach 2:
The patent employs elastic positioning mechanisms that can dynamically adjust to maintain contact between plates during the stamping process. The elastic components allow for slight movements and adjustments while maintaining consistent pressing force, ensuring the seal remains positioned accurately throughout the dynamic pressing operation. This dynamic capability resolves the instability issue inherent in static magnetic attraction systems.
2Stability of the object's composition
If conventional positioning systems are used, then the plates can be connected, but the seal is stressed unevenly resulting in different shades of color
Solution Approach 1:
The patent implements multiple elastic positioning mechanisms at different locations (first, second, third, fourth elastic positioning mechanisms) rather than a single centralized connection point. Each mechanism independently applies pressing force at its local position, ensuring uniform stress distribution across the seal surface. This local quality approach resolves the stress uniformity issue by distributing the pressing force through multiple contact points rather than concentrating it at one location.
3Manufacturing precision
If positioning mechanisms are added to improve alignment, then the stamping accuracy improves, but the device complexity increases
Solution Approach 1:
The elastic positioning mechanisms are designed to automatically align and position the plates through their elastic deformation characteristics. The mechanisms self-adjust during the pressing operation, eliminating the need for complex external positioning systems or manual alignment procedures. This self-service capability achieves high stamping accuracy while keeping the device structure relatively simple, as the positioning function is integrated into the pressing mechanisms themselves rather than requiring separate positioning systems.

Implementation Method 3

AI summary
A seal stamping machine has two pressing plates disposed face to face, each plate being capable of compressing a stamp, and a stamping carrier is located between the plates. The first plate has a plurality of positioning holes and the second plate has a corresponding plurality of elastic positioning mechanisms, each elastic positioning mechanism corresponding to one of the plurality of positioning holes; when the plates are pressed together, the elastic positioning mechanisms urge the first plate away from the second plate. The plates are aligned by the positioning holes and the elastic positioning mechanisms in order to align the stamping carrier and avoid displacement. A seal is thus uniformly stamped.
