Problems solved by technology
[0004] (1) Slow measurement speed and low work efficiency
Fiber diameter measurement by projection microscopy is performed manually one by one in a dark room, so the measurement speed is very slow and the work efficiency is low
[0005] (2) High cost
The measurement speed of projection microscopy is slow and labor-intensive. In actual measurement, it is necessary to employ more people and purchase more instruments, which virtually increases the cost.
[0006] (3) Low measurement accuracy
[0008] (1) The drive motor of the microscope table is suspended on one side, so the force is not uniform;
[0009] (2) The image acquisition card selected by the instrument is a high-speed image card, so its production cost is very expensive, and its versatility is also greatly reduced;
The switchability of this light source causes the complexity of light source manufacturing and control;
[0011] (4) The software working platform is under DOS, and the data files cannot be shared with other software, and there is no management function;
[0012] (5) The product is very expensive, which greatly limits its wide application

Embodiment Construction
[0047] Such as figure 1As shown, the present invention is aimed at the fiber size measurement method, and the special microscopic device designed includes an eyepiece 3, an objective lens 4, a sample stage 6, and a light source 7. The sample stage is placed under the objective lens, and the light source 7 is placed under the sample stage 6; it also includes a camera. 1 and interface attachment 2. The camera 1 is placed above the microscope device through the interface accessory 2. The light source 7 is a laser or a monochromatic light source. The sample stage 6 is a stepper motor driven workbench, which includes a base 12 , a worktable 8 in the x direction, a worktable 9 in the y direction, a stepper motor 14 in the x direction and a stepper motor 10 in the y direction. The base 12 is fixed on the stage of the sample stage of the micro-device. There are male slides in the y direction on both sides of the base 12. There are balls 13 in the slides, and a rack 11 is fixed on on...

Description
technical field [0001] The invention relates to a method and device for measuring fiber size, belonging to the technical field of micro-measurement. Background technique [0002] Parameters such as fiber diameter are important symbols to measure the quality of its products, and these parameters have been accepted as international standards by the International Wool Fiber Organization (IWTO). In order to measure fiber diameter and related parameters, a series of methods have been developed internationally. Among them, the more mature and widely used methods include projection microscopy and methods based on computer image analysis. [0003] The development of projection microscopy is relatively mature and is widely used in our country, but it has many insurmountable shortcomings. These disadvantages are mainly: [0004] (1) The measurement speed is slow and the work efficiency is low. The fiber diameter measurement of the projection microscopy method is carried out manual...
