During the positioning process, the staff can tighten the fabric to ensure the flatness of the surface to be tested.

Finally, since the square frame is rotatably installed inside the rectangular groove, the staff can flip the square frame over to directly detect the other side of the fabric, which effectively improves work efficiency, eliminates the need to reinstall the fabric, and saves time.

[0015] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1-Figure 10 An infrared fabric detection device shown includes a detection mechanism 1, a frame box 2 is provided at the middle end of the top of the detection mechanism 1, an opening 3 is provided at the bottom in front of the frame box 2, a telescopic frame 4 is movably provided inside the opening 3, a driving mechanism is provided inside the frame box 2, and the driving mechanism can control the telescopic frame 4 to be extended and retracted at the opening 3, a rectangular groove 20 is provided on the surface of the telescopic frame 4 at one end of the outer side of the frame box 2, a square frame 22 is rotatably installed inside the rectangular groove 20, a rotating shaft is provided at the middle end of both sides of the square frame 22, and the rotating shaft is rotatably installed on the inner wall of the rectangular groove 20 so that the square frame 22 can rotate freely as a whole, and a clamping mechanism is installed on both sides inside the square frame 22, and the clamping mechanism is used to position the fabric, and by setting the driving mechanism, the telescopic movement of the telescopic frame 4 at the opening 3 can be operated to ensure the consistency of the fabric detection position and reduce human errors, and at the same time, a clamping mechanism is provided to clamp the end of the fabric to realize the positioning of the fabric, and the square frame 22 is rotatably installed inside the rectangular groove 20, so that the other side of the fabric can be detected, which effectively improves the work efficiency, does not need to reinstall the fabric, and saves time.

[0018] The driving mechanism includes a first gear 6, which is rotatably installed in the middle of the frame box 2. A moving block 5 is slidably installed inside the frame box 2 and in front of the first gear 6. Two first sliders 7 are symmetrically slidably installed inside the frame box 2 and behind the first gear 6. A first rack 8 is provided on the surface of the moving block 5 close to the first gear 6, and a second rack 9 is provided on the surface of the first slider 7 close to the first gear 6. The first rack 8 and the second rack 9 are both meshed with the first gear 6. Through the meshing of the first gear 6 with the first rack 8 and the second rack 9, the rotation of the first gear 6 can be converted into a linear motion of the moving block 5, thereby driving the two first sliders 7 to make a linear motion, thereby realizing the displacement of the moving block 5 and the first slider 7. The first gear 6, as the core component of the drive, only needs to control the rotation direction of the first gear 6 to accurately control the movement direction of the moving block 5 and the first slider 7, thereby controlling the telescopic degree of the telescopic frame 4.

[0019] Two support frames 12 are symmetrically installed between the two first sliders 7, and a second gear 11 is rotatably installed between the two support frames 12. The two support frames 12 position the second gear 11 to ensure the stability of the second gear 11 when in use. A stepper motor 10 is installed on the surface of one of the support frames 12, and the output end of the stepper motor 10 is connected to the second gear 11. The second gear 11 is meshed with the first gear 6, further improving the driving mechanism. The stepper motor 10 directly drives the first gear 6 through the second gear 11.

[0020] The surface of the telescopic frame 4 is provided with a T-shaped slider, and the bottom end of the frame box 2 is provided with a T-shaped slide groove, and the T-shaped slider is slidably installed in the T-shaped slide groove. The T-shaped slider on the telescopic frame 4 cooperates with the T-shaped slide groove at the bottom end of the frame box 2, which can provide precise guidance for the telescopic movement of the telescopic frame 4, ensuring that the telescopic frame 4 is telescoped along a predetermined straight line trajectory, thereby improving the accuracy of fabric positioning and ensuring the accuracy of the detection position. Two second connecting frames 19 are symmetrically installed at one end of the telescopic frame 4 inside the frame box 2, an extension block 13 is fixedly installed at the bottom of the first slider 7, a frame groove 14 is provided on the surface of the extension block 13, and a guide column 16 is movably installed inside the frame groove 14, and the surface of the guide column 16 movably passes through the extension block 13, and a fixed disk is provided on the top of the extension block 13, and a first spring 15 is installed on the surface of the guide column 16 and between the fixed disk and the frame groove 14, a first connecting frame 17 is movably provided below the extension block 13, and the bottom of the guide column 16 is fixedly connected The first connecting frame 17 is connected to the second connecting frame 19 by a rotating shaft with a connecting rod 18. The elastic force of the first spring 15 can make the top of the first connecting frame 17 always close to the bottom of the extension block 13. When the first slider 7 slides toward the top of the frame box 2, under the action of the connecting rod 18, the telescopic frame 4 will be pulled into the frame box 2 by the tension. When the telescopic frame 4 is completely moved into the frame box 2, the end face of the second connecting frame 19 is close to the inner wall of the frame box 2. At this time, there is still a distance between the moving block 5 and the telescopic frame 4. Then the first slider 7 continues to move upward, and the inner wall of the frame groove 14 has an extrusion force on the first spring 15, causing the first spring 15 to contract. The position of the telescopic frame 4 will not change, and the moving block 5 will continue to move downward. Finally, the pressing piece at the bottom of the moving block 5 will press the fabric. This staged and logical movement method accurately meets the operational requirements of first positioning the fabric and then pressing the fabric during fabric detection, and the operation process is smooth and efficient.

[0021] A bottom groove 33 is provided at the bottom of the rectangular groove 20, and a stopper 34 is slidably installed inside the bottom groove 33. A docking groove 23 is provided on the middle end surface of the square frame 22, and the docking groove 23 corresponds to the stopper 34. When the square frame 22 rotates inside the rectangular groove 20, the end surface of the docking groove 23 will squeeze the surface of the stopper 34, and the stopper 34 plays a limiting role to prevent the square frame 22 from excessively rotating in the rectangular groove 20, thereby ensuring the accuracy of fabric detection. The cooperation between the stopper 34 and the docking groove 23 can ensure that the rotation of the square frame 22 is carried out within a safe and effective range.

[0022] The clamping mechanism includes a semicircular groove 24, which is opened on both sides of the square frame 22. A polished rod 25 is rotatably installed inside the semicircular groove 24. A semi-cylinder 26 is provided on the surface of the polished rod 25. A plurality of convex points are provided on the surface of the semi-cylinder 26. The surface of the semi-cylinder 26 is movably arranged in the semi-circular groove 24. The end of the fabric is installed in the semi-circular groove 24. The fabric is positioned by squeezing the semi-cylinder 26 on the fabric. The end of the fabric can be directly placed in the semi-circular groove 24, and then the squeezing of the semi-cylinder 26 is used to achieve positioning. There is no need for cumbersome fixing devices and complicated operating steps. The operator can quickly complete the clamping of the fabric, thereby improving the efficiency of the detection work. At the same time, the plurality of convex points provided on the surface of the semi-cylinder 26 greatly increase the friction between the fabric and the fabric.

[0023] The four end corners of the square frame 22 are all provided with movable grooves 27, and a second spring 30 is arranged inside the movable groove 27. The end of the second spring 30 is connected to an L-shaped slider 28, and the end of the L-shaped slider 28 protrudes into the docking groove 23. An arc groove 31 is arranged on the side of the movable groove 27, and a third gear 32 is rotatably installed inside the arc groove 31. The end of the light rod 25 is fixedly connected to the third gear 32. A third rack 29 is arranged on the surface of the L-shaped slider 28, and the third rack 29 is meshed with the third gear 32. The existence of the second spring 30 provides a buffering effect for the movement of the L-shaped slider 28. During the detection process, even if there are some slight vibrations or external force impacts, the second spring 30 can absorb part of the energy to avoid the square frame 22 and the telescopic frame 4 The hard collision between the two gears protects the equipment structure from damage, and also reduces the position change of the fabric caused by vibration. The elastic force of the second spring 30 can ensure that the L-shaped slider 28 always maintains a good meshing state with the third gear 32 during normal detection, thereby ensuring the reliability of the transmission. When the staff installs the fabric, the L-shaped slider 28 can be pushed into the depth of the movable groove 27, so that the third gear 32 rotates, and the light rod 25 rotates synchronously. At this time, the semi-cylinder 26 will move out of the semi-circular groove 24, and a certain gap will be left between the light rod 25 and the semi-circular groove 24. The end of the fabric can pass through the gap, and finally the thrust on the L-shaped slider 28 is released. The L-shaped slider 28 can automatically reset under the action of the second spring 30, thereby realizing the clamping operation of the end of the fabric.

[0024] Two limit blocks 21 are symmetrically installed at one end of the telescopic frame 4 outside the opening 3, and the limit blocks 21 are installed at the end of the telescopic frame 4. When the telescopic frame 4 is fully retracted into the interior of the frame box 2, the limit blocks 21 can be close to the outer surface of the frame box 2, further ensuring the positioning of the telescopic frame 4.

[0025] The stopper 34 is located between the two L-shaped sliders 28 , and a certain distance is left between the stopper 34 and the L-shaped slider 28 , and a spacing of 1 cm is left between the stopper 34 and the L-shaped slider 28 to prevent the stopper 34 from accidentally touching the L-shaped slider 28 .

[0026] Working principle: First, start the stepper motor 10, and directly drive the first gear 6 to rotate in the positive direction through the second gear 11. At this time, the moving block 5 moves upward to the frame box 2 as a whole, and the first slider 7 moves downward to the frame box 2 as a whole. Under the action of the first connecting frame 17, the second connecting frame 19 and the connecting rod 18, the telescopic frame 4 can be pushed from the opening 3 to the outside of the frame box 2. Then the staff pushes the L-shaped slider 28 to the depth of the movable groove 27, so that the third gear 32 rotates, and the light rod 25 rotates synchronously. At this time, the semi-cylindrical 26 will move out of the semicircular groove 24, leaving a certain gap between the light rod 25 and the semicircular groove 24, and the end of the fabric can pass through the gap. Finally, the thrust on the L-shaped slider 28 is released, and the L-shaped slider 28 can automatically reset under the action of the second spring 30 to achieve the clamping operation of the end of the fabric. Then the staff rotates the square frame 22 to keep the square frame 22 horizontal. Next, the stepping motor 10 is started to directly drive the first gear 6 to rotate in the opposite direction through the second gear 11. At this time, the moving block 5 moves as a whole to the bottom of the frame box 2, and The first slider 7 moves upwardly as a whole, and under the action of the first connecting frame 17, the second connecting frame 19 and the connecting rod 18, the telescopic frame 4 can be pulled to move from the opening 3 to the inside of the frame box 2. When the telescopic frame 4 is completely moved into the frame box 2, the limit block 21 is close to the outer surface of the frame box 2, and the end face of the second connecting frame 19 is close to the inner wall of the frame box 2. At this time, there is still a distance between the moving block 5 and the telescopic frame 4, and then the first slider 7 continues to move upward, and the inner wall of the frame groove 14 has a squeezing force on the first spring 15, so that the first spring The spring 15 contracts, the position of the telescopic frame 4 does not change, and the moving block 5 continues to move downward, and finally the pressing plate at the bottom of the moving block 5 presses the fabric tightly to realize the detection of the fabric. Due to the different materials of the fabric, when facing double-sided fabric, it is necessary to detect the other side of the fabric. At this time, it is necessary to move the telescopic frame 4 to the outside of the frame box 2 again. The staff directly flips the square frame 22, and then operates the telescopic frame 4 to move to the inside of the frame box 2, so as to realize double-sided detection of the fabric.
