Background technology:
The current structure of the fiber strength tester includes a force sensor, a first connecting rod, an upper clamp, and a lower clamp. Figure 2 shows an application example in this environment, where the lower clamp is connected to a moving platform via a second connecting rod. The fiber material is directly clamped between the upper and lower clamps. During the experiment, the moving platform moves to measure the strength of the fiber.
However, this structure has the following problems:
1. This structure is for on-line sample preparation, clamping a single fiber directly between the upper and lower clamps. However, it cannot be used for on-line sample preparation of micro-nano fibers that are extremely fine and have very low strength;
2. The sensor used in this structure has a large range but low precision, making it suitable only for measuring the strength of conventional fibers. For micro-nano fiber materials that are extremely fine and have very low strength, the precision of this sensor is insufficient to measure accurate data, which hinders the research on the physical properties of micro-nano fiber materials;
3. The force sensors used in this structure have a large range but low precision; for force sensors with a small range and low precision, using the online sample preparation method can easily damage the sensor, affecting the accuracy of the data measured by the instrument.
Technical implementation elements:
In view of the disadvantages of the existing technology described above, the object of the present invention is to provide a force measurement module for measuring the strength of micro-nano single fiber materials, which can measure force more accurately.
To achieve the above object and other related objects, the present invention provides a force measurement module for measuring the strength of micro-nano single fiber materials, comprising a force sensor, an upper connector connected to the force sensor, a lower connector connected to the upper connector, an upper clamp connected to the lower connector, and a lower clamp used in conjunction with the upper clamp.
1. The upper connector is an upper hook, and the lower connector is also a lower hook, and the upper hook and the lower hook have the same shape and dimensions.
2. The fiber material is a single fiber, and at the same time, the fiber is of micrometer or nanometer scale.
3. Both ends of the upper hook and the lower hook are provided with a U-shaped bend, and the two are connected together through the U-shaped bend.
4. The lower hook and the upper clamp are threadedly fixed together.
In actual use, a nanofiber sample stage is connected between the upper and lower clamps. The lower clamp is connected to a motion platform via a connecting rod. During the experiment, the motion platform moves to measure the tensile strength of the micro-nano fiber material.
As described above, the force measurement module for measuring the tensile strength of micro-nano single fiber materials of the present invention has the following beneficial effects:
