[0002] With the progress of modern materials science, new materials emerge in an endless stream, and processing technology is also constantly improving. The classification of materials has become diversified and field-oriented. It is not only limited to the composition and physical and chemical properties. There are more and more comprehensive classification forms in the application field, processing characteristics, etc. Flexible materials are such an emerging classification. Literally, the concept of "flexibility" in terms of physical properties is relatively broad. In fact, it is mainly defined by the processing method and physical properties of the materials. Flexible materials often need to be tested after production, and the bending performance is an important indicator for evaluating the performance of flexible materials. In the existing technology, there is a lack of visual testing for flexible materials, and the test results are single data, which cannot intuitively express the meaning of the data.

[0003] In order to solve the above problems, the present application proposes a visual flexible material bending performance measurement device. Summary of the invention

[0004] (I) Purpose of the invention

[0005] In order to solve the technical problems in the prior art of the background technology that there is a lack of visual detection for flexible materials, the detection result data is single, and the meaning of the data cannot be expressed intuitively, the present invention proposes a visual flexible material bending performance measurement device. According to the needs of different fiber samples, the present invention has multiple different friction surfaces to choose from, and at the same time, a cylinder motion module is added to the free end of the sample, and the entire process of natural recovery of the sample can be recorded through the visual observation module.

[0006] (II) Technical solution

[0007] In order to solve the above problems, the present invention provides a visual flexible material bending performance measurement device, including a sample fixing end, a sample free end, a control box, a CCD image acquisition module and a backlight module;

[0008] The sample fixing end is arranged on the control box, and the sample fixing end comprises a motion platform, a base, a driving device and a sample clamp; a slide groove is arranged on the base, the motion platform is slidably connected with the slide groove, the driving device is arranged on the motion platform, and the sample clamp is installed on one side of the driving device and is transmission-connected with the driving device;

[0009] The control box is provided with a cylinder controller and a cylinder, and the cylinder controller is connected to the cylinder control; the control box is provided with a guide rail; the free end of the sample is slidably set on the guide rail and is connected to the cylinder transmission; the free end of the sample includes a fixed frame, a pressure sensor and a differential friction surface turntable; the fixed frame is installed on the top of the pressure sensor, and the pressure sensor is communicatively connected to the control box; the fixed frame is provided with a second motor, and the differential friction surface turntable is provided with an electric control turntable and a plurality of electric control friction surfaces distributed in a ring array; the differential friction surface turntable is provided with a transmission rod, and the transmission rod is connected to the second motor transmission; a plurality of first motors are provided on the back of the differential friction surface turntable, and each first motor is connected to an electric control friction surface transmission.

[0010] Preferably, the sample fixing end and the sample free end are arranged in parallel, and a detection area is formed between the sample fixing end and the sample free end.

[0011] Preferably, the CCD image acquisition module and the backlight module are arranged side by side on the control box, and the CCD image acquisition module and the backlight module are located on both sides of the detection area, and the CCD image acquisition module is communicatively connected with the control box.

[0017] The above-mentioned technical scheme of the present invention has the following beneficial technical effects: the present invention has a plurality of different friction surfaces to choose from according to the needs of different fiber samples, and the friction surfaces are distributed circumferentially. The switching of the friction surfaces is controlled by a stepper motor (second motor). Compared with manual replacement of friction surfaces, this instrument greatly improves the experimental efficiency. Each friction surface is equipped with a first motor, which can realize the self-rotation of a single friction surface, and can cooperate with the driving device at the fixed end of the sample to realize synchronous rotation, thereby changing the angle of the bent fiber sample in the imaging of the CCD image acquisition module, so that the CCD image acquisition module can observe the bent sample at the best angle. The present invention adds a cylinder motion module to the free end of the sample. When the sample is in a bent state, the pneumatic device causes the free end to rebound quickly. At this time, the sample is still in a bent state, and the entire process of the sample's natural recovery can be recorded by the visual observation module. BRIEF DESCRIPTION OF THE DRAWINGS
