Description

Technical Field

[0001] The invention relates to the technical field of mite detection, and in particular to an intelligent counter for anti-mite detection of textile cloth. Background Art

[0002] Mites are a kind of pests that are not easily visible to the naked eye. They live in dust, clothing, bedding, etc., and are prone to cause allergic reactions and skin diseases. In recent years, with the development of society and the improvement of people's health awareness, the anti-mite function of textiles has received more and more attention.

[0003] In terms of anti-mite performance testing, the counting function of mites in different states is the same, so how to count mites effectively and accurately is crucial. There are two commonly used methods for counting mites: area method and volume method. Both methods are sampling statistics. Due to the strong mobility of mites and their uneven distribution on the surface of textiles, both methods have large errors.

[0004] At present, a relatively reliable method is to count the mites on the entire sample surface.

[0005] Specific operation steps: add a certain number of live mites to the surface of the textile sample, and count the live mites on the surface of the textile sample after a period of time. The specific counting method is to use a microscope and manual counting method, count the local area of ​​the sample surface each time, and finally count the mites on the entire sample surface by changing the observation field of the microscope. There are several disadvantages of using a microscope and manual counting method: 1. The microscope has a small field of view, and the observation area needs to be switched multiple times. For a relatively large area of ​​a textile sample, the observation time is long. In addition, the movement of living mites will lead to repeated counting of the same individual in multiple fields of view.

[0006] 2. Mites are small in size, and manual counting of mites is time-consuming, laborious and prone to errors.

[0007] Therefore, it is necessary to develop an intelligent counter for anti-mite detection of textile fabrics. Summary of the invention

[0008] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide an intelligent counter for anti-mite detection of textile fabrics.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions: An intelligent counter for anti-mite detection of textile cloth comprises a frame, an imaging core, a lens, a light source and a sample table which are arranged on the frame in sequence from top to bottom, a culture dish is placed on the sample table, and the imaging core is electrically connected to an industrial control machine; the imaging core is used to photograph the textile cloth carrying mites in the culture dish through the lens, and the light source is used to provide auxiliary lighting for the culture dish.

[0010] As a further improvement of the above technical solution, the imaging movement is an area array camera body.

[0011] As a further improvement of the above technical solution, the lens is a transmission optical lens group.

[0012] As a further improvement of the above technical solution, the light source emits white light and the incident angle to the culture dish is 30°~60°.

[0013] As a further improvement of the above technical solution, the sample stage includes a base, a platform arranged above the base, a clamping seat placed on the platform, and a horizontal adjustment structure for fixing the clamping seat.

[0014] As a further improvement of the above technical solution, the clamping seat is in a truncated cone shape and a clamping groove is provided at the center of its top surface; a positioning soft rubber for adapting to the culture dish is provided in the clamping groove.

[0015] As a further improvement of the above technical solution, the horizontal adjustment structure includes a ring body that is sleeved on the periphery of the clamping seat, and a front adjusting screw, a rear adjusting screw, a left adjusting screw and a right adjusting screw are arranged on the ring body. The front adjusting screw and the rear adjusting screw are coaxially arranged opposite to each other, and the left adjusting screw and the right adjusting screw are coaxially arranged opposite to each other, and the front adjusting screw, the rear adjusting screw, the left adjusting screw and the right adjusting screw are all facing the inclined surface of the clamping seat.

[0016] As a further improvement of the above technical solution, a lifter is provided on the base, the output end of the lifter is connected to the bottom surface of the platform, two guide cylinders are provided on the base, and the bottom surface of the platform is provided with vertical rods with the same number as the guide cylinders and slidably connected.

[0017] As a further improvement of the above technical solution, a vibrator is provided on the platform.

[0018] The beneficial effects of the present invention are as follows: compared with traditional manual mite counting technology, the intelligent counter forms a large-field global imaging through automated shooting, and then can efficiently and accurately count the live mites on the textile cloth samples through an industrial computer, greatly reducing the workload and pressure of manual counting, eliminating the need for long-term microscope observation and tedious counting work, enabling operators to complete anti-mite detection tasks more easily, and reducing the complexity and error probability of manual operations.

DETAILED DESCRIPTION

[0022] The present invention provides an intelligent counter for anti-mite detection of textile fabrics. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0023] See also Figure 1 and Figure 2 The present invention provides an intelligent counter for anti-mite detection of textile cloth, comprising a frame 1, an imaging movement 2, a lens 3, a light source 4, and a sample table 5 arranged on the frame 1 from top to bottom, a culture dish 6 is placed on the sample table 5, and the imaging movement 2 is electrically connected to an industrial control machine; the imaging movement 2 is used to photograph the textile cloth carrying mites in the culture dish 6 through the lens 3, and the light source 4 is used to provide auxiliary lighting for the culture dish 6.

[0024] In actual work, a piece of textile cloth sample is placed on a circular culture dish 6 with a diameter of 58 mm, and about 2000 mites are placed therein. The size of the textile cloth sample is φ58 mm, the size of the mites is 100 μm~500 μm, and they have four pairs of legs. The diameter of the adult legs is about 20 um. The culture dish 6 is then placed on the sample table 5, and then timing is performed until the specified time is reached. The remaining living mites on the textile cloth sample are counted. Specifically, the imaging movement 2 forms a shooting efficiency with a large field of view, high resolution, short object distance and low distortion through the lens 3, and the entire culture dish 6 area is video-captured and imaged. Finally, the video image is transmitted to the industrial computer. The industrial computer locates each target mite by analyzing the video image and compares the appearance changes of each mite between adjacent image frames (such as the difference in the swing of the insect legs), so as to count and accurately screen them into living mites.

[0025] Compared with traditional manual technology, the intelligent counter forms a large-field global imaging through automated shooting, and then can efficiently and accurately count the live mites on textile fabric samples through an industrial computer, greatly reducing the workload and pressure of manual counting. There is no need for long-term microscope observation and tedious counting work, allowing operators to complete anti-mite detection tasks more easily, reducing the complexity and error probability of manual operations.

[0026] It should be noted that since mites are milky white and some textiles are white, it is difficult to distinguish the sample background from the mites by directly imaging the sample, so the sample needs to be processed. The processing method used is to add dye to the fabric sample to make the color of the fabric sample darker, and the mites float on the dye to appear milky white.

[0027] In this embodiment, the imaging movement 2 is a surface array camera body. The surface array camera can obtain image information of a large area at one time. Compared with the traditional microscope, when shooting the culture dish 6 area, it can cover the entire area more comprehensively. For the circular culture dish 6 with a diameter of 58 mm and the textile cloth samples therein, it can be photographed at a wider viewing angle, reducing the time waste and possible omission or repeated counting problems caused by the need to switch the observation area multiple times due to the narrow field of view. For example, when testing a large area of ​​textile cloth samples, the traditional method may require multiple movements of the microscope field of view and splicing images, which is a cumbersome and error-prone process, while the surface array camera can obtain a complete image at one time, greatly improving the detection efficiency and accuracy. In addition, the surface array camera body can provide high-resolution images, which can clearly present the morphological characteristics of small organisms such as mites. When counting mites and distinguishing between living and non-living mites, high-resolution images help to more accurately identify the appearance changes of mites, such as subtle movements such as the swinging of insect feet. This is crucial for accurately screening out living mites by comparing the changes in the appearance of mites between adjacent image frames. It can effectively reduce misjudgment caused by image blur and improve the accuracy and reliability of counting.

[0028] The lens 3 is a transmission optical lens group. The transmission optical lens group has a high light transmittance, which allows more light to pass through the lens 3 to reach the imaging movement 2 (the main body of the area array camera). During the operation of the intelligent counter, the light emitted by the light source 4 is used to assist in illuminating the culture dish 6, and the transmission lens 3 can efficiently transmit these lights, so that the textile cloth and mites in the culture dish 6 are fully illuminated. Adequate light illumination helps to improve the brightness and contrast of the image, making the mites more clearly visible in the image, thereby improving the accuracy and reliability of the counting. In order to better meet the shooting requirements of large field of view, high resolution, short object distance and low distortion, the following is an example of a lens combination of a transmission optical lens group, which is sequentially combined with a first meniscus lens with a convex surface facing the object, a biconvex lens, a meniscus lens with a concave surface facing the image, a biconvex lens, a plano-convex lens, a meniscus lens with a concave surface facing the object, and a meniscus lens with a convex surface facing the image.

[0029] In this embodiment, the light source 4 emits white light. When dyeing a textile cloth sample with a dye, in order to prevent the liquid surface reflected light from affecting the imaging quality, the incident angle on the culture dish 6 is 30°~60°, and the optimal incident angle is 45°.

[0030] Specifically, the sample stage 5 includes a base 51, a platform 52 arranged above the base 51, a clamping seat 53 placed on the platform 52, and a horizontal adjustment structure 54 for fixing the clamping seat 53. The platform 52 is arranged above the base 51, and provides a flat mounting surface for the clamping seat 53. The flat platform 52 can ensure that the clamping seat 53 is placed thereon stably without tilting or unevenness, thereby ensuring the stability of the culture dish 6 on the clamping seat 53. When imaging and shooting, the stable position of the culture dish 6 helps to obtain clear and accurate images, avoid image blur or distortion caused by sample shaking, and improve the accuracy of mite counting. The horizontal adjustment structure 54 is used to fix the clamping seat 53, which can fine-tune the horizontal position of the clamping seat 53 and ensure that it can be firmly fixed after adjustment. In actual operation, it may be necessary to accurately place the culture dish 6 at the center of the field of view of the imaging movement 2 and the lens 3, or adjust the position of the culture dish 6 according to different detection requirements. The clamping seat 53 can ensure the accurate position of the culture dish 6 on the sample stage 5 to prevent it from sliding or shifting during operation. The horizontal adjustment structure 54 can fine-tune the horizontal position of the clamping seat 53 and ensure that it can be firmly fixed after adjustment. In actual operation, it may be necessary to accurately place the culture dish 6 at the center of the field of view of the imaging movement 2 and the lens 3, or adjust the position of the culture dish 6 according to different detection requirements.

[0031] Furthermore, the clamping seat 53 is truncated cone-shaped and a clamping groove 531 is provided at the center of its top surface; a positioning soft glue 532 for adapting to the culture dish 6 is provided in the clamping groove 531. The setting of the positioning soft glue 532 further enhances the fixing effect of the culture dish 6. The positioning soft glue 532 has a certain elasticity and friction force, and can fit tightly with the bottom of the culture dish 6, thereby increasing the adhesion between the culture dish 6 and the clamping seat 53. During the detection process, even if it is slightly vibrated or subjected to external force, the culture dish 6 can remain in place through the buffering and fixing effect of the soft glue. At the same time, the soft glue can also protect the bottom of the culture dish 6 to avoid scratches or damage during the clamping process.

[0032] Further, the horizontal adjustment structure 54 includes a collar body 541 sleeved on the periphery of the clamping seat 53, a front adjustment screw 542, a rear adjustment screw 543, a left adjustment screw 544 and a right adjustment screw 545 arranged on the collar body 541, the front adjustment screw 542 and the rear adjustment screw 543 are coaxially arranged opposite to each other, the left adjustment screw 544 and the right adjustment screw 545 are coaxially arranged opposite to each other, and the front adjustment screw 542, the rear adjustment screw 543, the left adjustment screw 544 and the right adjustment screw 545 are all facing the inclined surface of the clamping seat 53. Under this layout, the front adjustment screw 542, the rear adjustment screw 543, the left adjustment screw 544 and the right adjustment screw 545 represent the application of component forces to the clamping seat 53 in the four directions of front, back, left and right in the horizontal dimension, thereby realizing the precise adjustment of the position of the clamping seat 53, and also having self-locking properties in the vertical and circumferential dimensions. In the actual detection process, due to various factors, the culture dish 6 may not be accurately in the optimal imaging position of the imaging movement 2 and the lens 3. By adjusting these four screws, the position of the clamping seat 53 in the front-back and left-right directions can be fine-tuned respectively to ensure that the culture dish 6 can be accurately located at the desired position. The front adjustment screw 542, the rear adjustment screw 543, the left adjustment screw 544 and the right adjustment screw 545 are preferably hand screws, and the operator can accurately control the moving distance of the clamping seat 53 by slowly rotating the screws, thereby achieving fine-tuning of the position of the culture dish 6.

[0033] In the anti-mite detection of textile fabrics, it may be necessary to adjust the height of the culture dish 6 according to the focal length of the imaging movement 2 and the lens 3, the observation habits of the operator and different experimental settings. The base 51 is provided with a lifter 71, and the output end of the lifter 71 is connected to the bottom surface of the platform 52. The base 51 is provided with two guide cylinders 72, and the bottom surface of the platform 52 is provided with vertical rods 73 that are the same in number as the guide cylinders 72 and are slidably connected, which provide guidance and support for the lifting and lowering movement of the platform 52. For some situations that require high-resolution imaging, the platform 52 can be raised or lowered by the lifter 71, so that the culture dish 6 can be at the optimal working distance of the lens 3, thereby obtaining a clearer and more accurate image of the mites and improving the counting accuracy. The lifter 71 can be an electric push rod or an electric screw lifter.

[0034] Preferably, a vibrator 8 is provided on the platform 52. In the actual detection process, mites may gather on the textile cloth in the culture dish 6 due to their own habits, the material characteristics of the textile or the initial state of placement. Before the detection, the role of the vibrator 8 is to disperse the mites that originally gathered together by generating vibrations of a certain frequency and amplitude, and distribute them more evenly on the surface of the textile cloth. In this way, counting errors caused by local aggregation of mites can be avoided, ensuring a comprehensive and accurate counting of mites in the entire culture dish 6 area.
