Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metallurgical sampling probes face challenges in automating the separation of samples from their housings, leading to complex structures, high maintenance costs, and issues with jamming due to component posture constraints.
Innovation Solution
An automatic separation device for sampling probes that utilizes a cutting device, inclined bottom plate, and posture adjustment devices to guide and separate the sample and housing components using gravity, minimizing actuation mechanisms and employing an adhesive tape that melts at high temperatures to secure the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal clamp is used to fix the two-piece mold box housing, then the housing remains securely combined during sampling, but the sample becomes difficult to separate from the housing when the clamp is overtightened
Solution Approach 1:
The patent changes the fixing mechanism from a mechanical clamp to an adhesive tape that burns and melts at high temperatures. During sampling, the adhesive tape maintains strong bonding between housing components, but at separation temperature, the tape melts and releases the sample automatically, resolving the contradiction between strong fixation and easy separation
Solution Approach 2:
The adhesive tape undergoes a phase transition from solid (providing strong bonding) to melted state (releasing sample) when exposed to high temperatures during the sampling process. This phase change enables automatic separation without manual intervention, solving the overtightening problem
2Extent of automation
If complex actuation mechanisms are used for automatic separation, then automation level increases, but device complexity and maintenance cost increase
Solution Approach 1:
The system achieves automatic separation through the self-service mechanism of the adhesive tape melting at high temperatures. The sample automatically separates from the housing without requiring external actuators, motors, or complex control systems, thus maintaining high automation while minimizing device complexity
Solution Approach 2:
The patent extracts the separation function from complex mechanical actuation systems and embeds it directly into the adhesive tape material itself. The tape's thermal response provides the separation capability inherently, eliminating the need for separate actuation mechanisms
3Productivity
If centrifugal devices and colliding bodies are used for separation, then sample separation is achieved in most cases, but jamming occurs due to arbitrary component postures
Solution Approach 1:
The patent replaces the mechanical separation system (centrifugal devices and colliding bodies) with a thermal-based separation mechanism. The adhesive tape melts due to heat from the molten metal sample, causing automatic separation without mechanical impact, thereby eliminating jamming issues associated with arbitrary component postures

AI summary
Provided are a sampling probe and a sampling probe automatic separation device, and a use method thereof. The sampling probe comprises a probe tail area (1) and a probe sampling area (2) connected to the top of the probe tail area (1). The probe sampling area (2) comprises a two-piece mold housing component (3) and a sample (4) disposed inside the two-piece mold housing component (3). The two-piece mold housing component (3) is wound and fixed by means of an adhesive tape capable of burning and melting. The automatic separation device comprises a cutting device (5) for cutting a sampling probe, and an inclined bottom plate. The front end of the inclined bottom plate is placed close to the cutting device (5). The inclined bottom plate gradually inclines downwards from the front end to the rear end. A first posture adjustment device (9), a first separation device (10), a second posture adjustment device (11), and a second separation device (12) are sequentially arranged between the front end and the rear end of the inclined bottom plate. Not only the problem that it is difficult to separate the sample from a housing can be effectively solved, but also the situation that an actuation mechanism is stuck with each component is avoided by constraint on the posture of each component.
