For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figures 1 to 6 As shown, a rapid detection device for fabric density is characterized in that: it includes an image acquisition component 1, a closing component 2, a backlight component 3, multiple magnetic clamps 4 and a host computer, the image acquisition component 1 is connected to the upper end surface of the closing component 2; the upper end surface of the backlight component 3 is detachably connected to the lower end surface of the closing component 2; the magnetic clamp 4 is adsorbed and connected to the upper end surface of the backlight component 3, and the magnetic clamp 4 is located in the closing component 2; the host computer is connected to the image acquisition component 1, the host computer is connected to the backlight component 3, and the host computer is also connected to a display component.

[0031] The fabric to be tested is placed between the backlight assembly 3 and the magnetic clamp 4, and the fabric to be tested is flattened and fixed by the adsorption effect of the magnetic clamp 4 and the upper end surface of the backlight assembly 3. The magnetic fixation method does not require the use of other tools, is fast and convenient, and will not damage the fabric, thereby improving the effectiveness of image acquisition;

[0032] The processing algorithm for fabric density detection based on image installed in the host computer is an existing technology (reference patent CN111208133A). The image information obtained by the image acquisition component is transmitted to the host computer for analysis, which can realize automatic detection of fabric density and improve the speed and accuracy of fabric density detection.

[0033] The sealing assembly 2 includes a sealing base 21 and a sealing cover 22, the sealing cover 22 is opened downward, and the sealing cover 22 is sleeved outside the sealing base 21. A rubber strip is provided at the contact point between the lower end surface of the sealing cover 22 and the upper end surface of the backlight assembly 3, and a plurality of magnetic clamps 4 are provided inside the sealing cover 22. A rubber strip is provided at the contact point between the lower end surface of the sealing base 21 and the upper end surface of the backlight assembly 3, and a plurality of magnetic clamps 4 are provided outside the sealing base 21.

[0034] The close base 22 can limit the range of the image acquisition component 1 to collect images, reduce the amount of image information analyzed by the host computer, and thus improve the detection speed. The sealing cover 22 is mounted outside the sealing base 21, which reduces the interference of the external environment on the image acquisition process of the image acquisition component. By providing a rubber strip at the contact point between the lower end face of the sealing cover 22 and the upper end face of the backlight assembly 3, the contact point can be tightly fitted to block external light from entering the interior of the sealing cover 22, and buffering can also be achieved. By providing a rubber strip as a buffer at the contact point between the lower end face of the sealing base 21 and the upper end face of the backlight assembly 3, damage to the backlight assembly 3 is prevented when the closed assembly 2 is installed, the service life of the backlight assembly 3 is increased, and the environmental interference outside the sealing base 21 is also isolated.

[0035] The backlight assembly 3 includes a backlight box 31, the upper surface of the backlight box 31 is connected to the sealing assembly 2, and a light-transmitting glass plate 32 is arranged in the middle of the upper surface of the backlight box 31. The light-transmitting glass plate 32 is 10 cm long and 10 cm wide, and the center of the fabric to be measured is placed on the light-transmitting glass plate 32. Through the close fit between the backlight box 31 and the sealing base 21, the light outside the light-transmitting glass plate 32 is isolated, so that the image acquisition assembly 1 can only receive the light within the range of the light-transmitting glass plate 32.

[0036] The upper top surface of the backlight box 31 is also provided with a plurality of clamp limiting grooves 311 , which are arranged around the light-transmitting glass plate 32 . The bottom of the magnetic clamp 4 is provided with a protrusion, which matches the clamp limiting groove 311 .

[0037] The edge of the fabric to be tested is placed between the clamp limit groove 311 and the protrusion at the bottom of the magnetic clamp 4, and is fixed by the adsorption of the magnetic clamp 4. The magnetic clamp 4 is arranged away from the light-transmitting glass plate 32 to avoid the influence of the clamp on the image acquisition component 1. The image acquisition component 1 mainly collects the density information of the central part of the fabric to be tested, that is, the part of the fabric located above the light-transmitting glass plate 32.

[0038] A backlight plate 33 is disposed below the transparent glass plate 32 and abuts against the transparent glass plate 32. A light source 34 is disposed below the backlight plate 33 and is disposed in the backlight box 31, with the center of the light source 34 facing the center of the transparent glass plate 32.

[0039] The light reflected by the light source 34 is irradiated onto the fabric to be tested through the backlight panel 33 and the light-transmitting glass panel 32. Part of the light passes through the gaps between the warp and weft in the fabric and is received by the image acquisition component 1 and displayed as white. Part of the light is blocked by the warp and weft and cannot be received by the image acquisition component 1 and is displayed as black. The backlight panel can make the light emitted by the light source 34 even and vertically irradiate the lower surface of the fabric to be tested. The light-transmitting glass panel 32 can receive even light and frame the range of the image collected by the image acquisition component 1, so that the host computer only calculates the square area of ​​10cmx10cm, which improves the calculation accuracy while avoiding interference from other external structures such as the magnetic clamp 4.

[0040] A light source bracket 35 is also provided in the backlight box 31, and the two ends of the light source bracket 35 are fixedly connected to the two opposite sides of the backlight box 31, and the light source 34 is provided in the middle of the light source bracket 35. It is ensured that the angle of the light source 34 will not shake during the irradiation process, and the light can be evenly and vertically irradiated to the lower surface of the fabric to be measured, thereby improving the acquisition effect of the image acquisition component 1 and further improving the detection accuracy of the fabric density.

[0041] The image acquisition component 1 includes a lens 11 and a camera 12 . The lens 11 faces the light-transmitting glass plate 32 , and the camera 12 is connected to a host computer.

[0042] Working principle: turn on the power through the host computer, turn on the light source 34 and the image acquisition component 1, place the center of the fabric to be tested on the light-transmitting glass plate 32, and fix the upper and lower surfaces of the edge of the fabric to be tested to the upper top surface of the backlight box 31 by adsorption through the magnetic clamp 4. The bottom of the magnetic clamp 4 is provided with a protrusion, which matches the clamp limit groove 311 to achieve rapid positioning, so that the fabric to be tested is fixed more firmly, which is conducive to the flattening of the fabric to be tested; the sealing base 21 isolates the light in the non-light-transmitting glass plate 32 area, and the sealing cover 22 isolates the interference from the outside of the detection device. Rubber strips are provided on the lower end surfaces of the sealing base 21 and the sealing cover 22. When collecting images, it is necessary to make the sealing base 21 and the sealing cover 22 fit tightly with the upper top surface of the backlight box 31. At this time, the rubber strip can fill the gap to prevent interference from the external environment, and as a buffer, it will not generate concentrated stress on the backlight box 31, thereby improving the service life. The quality of the acquired images is observed through the display component, and the fabric density is automatically analyzed by the host computer, which improves the speed and accuracy of fabric density detection.
