Description

Technical Field

[0001] The utility model belongs to the technical field of textile fiber detection equipment, and particularly relates to a shooting device for fiber component analysis. Background Art

[0002] The analysis and testing of textile fiber composition is a crucial step in the textile industry. Traditional testing methods primarily include chemical methods and microscopic observation. Microscopic observation involves placing a textile sample on a glass slide. The inspector then uses the naked eye to discern the microscopic shape of the textile fibers, determine the type of fabric, and measure the dimensions. This long work schedule can lead to fatigue and reduced accuracy. With the advancement of science and technology, the application of AI image recognition technology in textile fiber composition analysis has made significant progress. By leveraging deep learning algorithms and image recognition technology, AI systems can automatically analyze and identify the fiber composition of textiles, significantly improving testing efficiency and accuracy.

[0003] Capturing high-quality images of textile samples is fundamental to textile fiber composition analysis equipment based on AI image recognition technology. Textile fibers are long, slender materials with diameters ranging from a few microns to tens of microns and lengths hundreds or even thousands of times greater than their diameters. To obtain high-quality, clear images of fiber samples, existing technologies employ microscopic imaging equipment, which uses an optical microscope to magnify the fiber sample and a camera to capture the magnified fiber sample image. Existing microscopic imaging equipment typically places a light source above the sample to be tested. The light source is then reflected from the sample, and the reflected light is used to form an image. However, the imaging effect for textile fibers is less than ideal, with objects lacking a sense of three-dimensionality. There are also significant deficiencies in capturing details, especially when capturing fine structures such as plush fiber scales. Details are severely lost, and the quality of textile fiber sample images needs to be improved. Utility Model Content

A glass slide 6 is provided on the carrier plate 4, and a first light source 51 capable of irradiating the upper surface of the glass slide 6 is provided in the microscopic imaging assembly 5.

[0030] Specifically, in this embodiment, the XY-axis moving platform 2 includes an X-axis linear module 21 and a Y-axis linear module 22, the Y-axis linear module 22 is connected to the support base 1, the X-axis linear module 21 is connected to the Y-axis linear module 22, and the lower surface of the loading plate 4 is connected to the X-axis linear module 21 through a connecting block 23.

[0031] Specifically, in this embodiment, the Z-axis drive assembly 3 includes a longitudinal column 31, a transverse movable arm 32, and an adjustment knob 33. The longitudinal column 31 is connected to the support base 1, one end of the transverse movable arm 32 is connected to the longitudinal column 31 so as to be movable along the Z axis, the microscopic imaging assembly 5 is connected to the other end of the transverse movable arm 32, and the adjustment knob 33 is connected to the longitudinal column 31. The adjustment knob 33 is used to adjust the position of the transverse movable arm 32 on the longitudinal column 31 and thus adjust the height of the microscopic imaging assembly 5.

[0032] Specifically, in this embodiment, the upper surface of the carrier plate 4 is provided with a first groove 41, which defines a light guide hole 42 extending through the lower surface of the carrier plate 4. The glass slide 6 covers the first groove 41, wherein the depth of the first groove 41 is preferably 8 mm to 12 mm. The lower surface of the carrier plate 4 is connected to the XY-axis moving stage 2 via the connecting block 23. The connecting block 23 defines a second groove 23a at a position corresponding to the light guide hole 42, and the second light source 7 is disposed in the second groove 23a. A double-sided mirror 8 is mounted at the bottom of the first groove 41 and covers the light guide hole 42.

Furthermore, a clip 43 is provided on the carrier plate 4, and the glass slide 6 is clamped and fixed to the first groove 41 by the clip 43.

[0033] Specifically, in this embodiment, the microscopic imaging assembly 5 includes a camera 52, a microscope objective lens 53, a first lens barrel 54, a second lens barrel 55, and the first light source 51.

[0035] Based on the above illumination structure: on the one hand, light sources are respectively set above and below the fiber sample, which increases the illumination intensity on the surface of the fiber sample, thereby improving the clarity of the fiber sample image; on the other hand, illumination is formed above and below the fiber sample, thereby increasing the three-dimensional sense of the fiber sample image; further, the transmitted light source below the sample to be tested can pass through the fiber sample to form bright transmitted light, which can help capture the details inside the fiber sample, such as fine structures such as plush fiber scales, and reduce the loss of detailed structures in the fiber sample image. Based on the above three aspects, the shooting device can improve the image quality of the captured textile fiber samples, and its application in textile fiber component analysis equipment based on AI image recognition technology can improve detection efficiency and accuracy.

[0036] As a preferred solution, in this embodiment, the cross-sectional size of the light guide hole 42 is set such that when the sample to be tested is placed on the glass slide 6, the projection of the sample to be tested on the first groove 41 falls within the light guide hole 42. Furthermore, the second groove 23a is larger than the light guide hole 42, and the projection of the light guide hole 42 on the connecting block 23 falls within the second groove 23a.

[0037] like Figure 1 As shown, the imaging device also includes a control circuit board 10, a communication module 20, a power module 30, and the like. The power module 30 connects to an external power source and provides power to each functional module.

The control circuit board 10 primarily issues control signals to each functional module, such as capture instructions for the microscopic imaging assembly 5 and movement instructions for the XY-axis motion stage 2. It should be noted that the circuit connections between the various functional modules are not shown in the figures.

The object carrier 4 and the adjustment knob 33 are exposed from the shell 40, and the shell 40 is reserved with an objective lens hole 40a for the microscope imaging component 5.

[0039] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
