Intelligent clamping system

Abstract

This invention provides a smart clamping system for detecting crispness, mainly composed of a measuring device and a fixing unit. The measuring device applies closing and compressive forces to a test sample and collects data through sensors, converting it into a crispness index. The components of this system that come into contact with the sample meet hygienic design requirements and are washable. By integrating the measuring device and fixing unit into a single device, this invention automates crispness measurement, improves product consistency, and reduces manual inspection costs.

Claims

A smart clamping system, comprising: A measuring device (1) includes: a clamping unit (11) disposed on both sides of the measuring device (1) to apply a clamping force to both sides of a sample to be tested; a first sensor (111) disposed on the clamping force transmission path of the clamping unit (11) and measuring a first pressure signal; a pressing unit (12) disposed on the top of the measuring device (1) and performing pressing, puncturing or crushing operations on the sample to be tested during downward stroke; a second sensor (121) disposed on the bottom of the pressing unit (12) and measuring a second pressure signal; and a fixing unit (2) disposed below the measuring device (1) for clamping or scooping up the sample to be tested and fixing it, wherein the pressing unit (12) reciprocates in the vertical direction relative to the fixing unit (2), and the clamping unit (11) is perpendicular to the mounting surface of the fixing unit (2) and reciprocates in the horizontal direction. During measurement, the sample to be tested is located between the clamping unit (11) and the pressing unit (12) to obtain the first pressure signal and the second pressure signal and to evaluate one of the brittleness characteristics of the sample to be tested.

2. The intelligent clamping system according to claim 1 further includes a first driving unit (13). When the sample to be tested is fixed to the fixing unit (2), the first driving unit (13) drives the clamping unit (11) to clamp until the first sensor (111) detects a force threshold or a breakage event.

3. In the intelligent clamping system according to claim 2, when the first sensor (111) detects the force threshold or the breakage event, it simultaneously records a corresponding travel distance and force-time and / or force-displacement data.

4. The intelligent clamping system according to claim 1 further includes a second driving unit (14). When the sample to be tested is fixed to the fixing unit (2), the second driving unit (14) drives the pressing unit (12) to press down until the second sensor (121) detects a force threshold or a breakage event.

5. In the intelligent clamping system according to claim 4, when the second sensor (121) detects the force threshold or the breakage event, it simultaneously records a corresponding travel distance and force-time and / or force-displacement data.

6. The intelligent clamping system according to claim 1 further includes a third driving unit (15) for driving the fixing unit (2) to clamp or scoop up the sample to be tested and fix it.

7. The intelligent clamping system according to claim 1, wherein the first sensor (111) and the second sensor (121) are selected from the group consisting of pressure sensors and load sensors.

8. The smart clamping system according to claim 1, wherein the clamping unit (11), the pressing unit (12) and the fixing unit (2) have replaceable clamps.

9. The intelligent clamping system according to claim 8, wherein the replaceable clamp is made of a material selected from the group consisting of rubber, plastic and metal.

10. The intelligent clamping system according to claim 9, wherein the materials of the parts of the measuring device (1) and the fixing unit (2) in contact with the sample include stainless steel.

11. The intelligent clamping system according to claim 10, wherein no opening gap is formed at the internal angle between the measuring device (1) in contact with the sample and the fixing unit (2), and the structure is constructed by continuous welding and grinding the weld to be flush with the adjacent surface.

12. The intelligent clamping system according to claim 1, wherein the contact surface between the measuring device (1) and the fixing unit (2) in contact with the sample is a continuous smooth surface, and a rounded corner transition is provided at the internal corner.

13. The intelligent clamping system according to claim 1, wherein the measuring device (1) and the fixing unit (2) in contact with the sample are washable structures.

14. The intelligent clamping system according to claim 1, wherein an inspection window is provided in the area in contact with the sample, the inspection window including an openable cover and / or a transparent window for visual or image inspection confirmation after cleaning.
