Description

Technical Field

[0001] The present invention relates to the technical field of fabric detection, and particularly relates to a fabric light transmittance detection device. Background Art

[0002] In the development process of the textile industry, fabric detection has always been a key link to ensure product quality and performance. Traditional fabric detection equipment has played an important role in quality control for the industry for a long time. However, with the progress of technology and the continuous emergence of new fabric materials, its limitations have become increasingly prominent. Currently, the following problems exist in fabric detection: 1. Single detection dimension: Traditional equipment uses a fixed light source (such as a single-polarized light source), which cannot capture the light transmission direction sensitivity of anisotropic materials; 2. Insufficient spectral coverage: The detection range of conventional sensors is mostly limited to the visible light band (380 - 780 nm), making it difficult to identify ultraviolet / infrared transmission characteristics (such as the detection limitations of polyester films); 3. Poor environmental adaptability: Lack of temperature / humidity / stress coupling detection modules, unable to evaluate the dynamic changes in light transmission of environment-responsive materials; 4. Defect marking damage: Mechanical contact marking (such as clamping components) is prone to cause damage to the nano-coating; Therefore, we propose a fabric light transmittance detection device to solve the above problems.

On the upper end of the inspection box, there is an annular fixing frame. On the annular fixing frame, there is a rotating mechanism. On the rotating mechanism, there are eight light source detection units. On both sides of the inspection box, there is a nitrogen delivery mechanism.

[0005] Preferably, the adsorption mechanism includes a clamping plate installed at one end of the intelligent robotic arm. One side of the clamping plate is connected to a loading frame.

The upper end of the closing plate penetrates through the side wall of the detection box and extends to the upper end of the detection box.

[0008] Preferably, guide rods are fixed between the opposite side walls inside the bearing box. One moving block on the same side penetrates through one guide rod on the same side. Gear sleeves are fixedly installed on both studs, and the two gears are connected by a chain.

The suction end of the vacuum pump 10 is connected to a suction pipe 13. One end of the suction pipe 13 is connected to one side of the bearing frame. When the vacuum pump 10 works, the adsorption holes 24 on the microporous ceramic plates 23 generate an adsorption force through the suction pipe 13, thereby realizing the adsorption of the fabric. When adsorbing different types of fabrics, the adsorption force can be controlled by adjusting the power of the vacuum pump 10 to ensure that the fabric can be firmly adsorbed without being damaged; Magnetic strips 25 are laid on the bottom of both the bottom plate 32 and the detection box 31. Rollers 9 are installed on both sides of the lower end of the AGV vehicle body 11. The magnetic induction device of the AGV vehicle body 11 corresponds to the magnetic strips 25. The magnetic strips 25 are made of high-magnetic materials with stable magnetic field intensity and uniform distribution, which can ensure that the AGV vehicle body 11 accurately travels along the preset path during movement, and the error can be controlled within ±5 mm), enabling the AGV vehicle body 11 to accurately transport the fabric into the detection box 31.

One end of the nitrogen storage mechanism 33 is connected with a nitrogen diversion pipe 30, and one end of the nitrogen diversion pipe 30 is connected to one end of the connecting pipe 28. When it is necessary to simulate a specific environment, the nitrogen in the nitrogen storage mechanism 33 enters the spray pipe 26 through the nitrogen diversion pipe 30, the connecting pipe 28, and the delivery pipe 29, and is then sprayed into the detection box 31 by the spray heads 27.

Since the moving block 15 is screwed onto the stud 16, and the two studs 16 rotate synchronously through the gear 19 and the chain 20, the moving block 15 will move along the guide rod 7, thereby driving the closing plate 17 to rise and opening the detection box 31. 3. Fabric transportation: The AGV vehicle body 11 moves by means of rollers 9 under the guidance of the magnetic strip 25, and sends the intelligent robotic arm 12 adsorbed with the fabric into the detection box 31, and places the fabric on the placement plate 4 of the carrying mechanism; 4. Detection preparation: The AGV vehicle body 11 exits the detection box 31, and the closing mechanism is started again, and the closing plate 17 descends to close the detection box 31; 5.
