Detailed Embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a surface defect detection device for carbon fiber fabric, which includes a workbench 1. Inside the workbench 1, there is a fixedly connected support block 11. A moving mechanism is connected to the side of the support block 11. One side of the moving mechanism is connected to a lifting mechanism. One side of the lifting mechanism is connected to an industrial camera 42. On one side of the workbench 1, there is a support leg 53. One side of the support leg 53 is connected to a winding mechanism; when the staff is ready to start the detection work, first install the carbon fiber fabric onto the winding mechanism, pull the fabric from one roller 5 to another roller 5, then the staff turns on the moving mechanism to adjust the relative position of the industrial camera 42 on the fabric, then turns on the lifting mechanism to adjust the height relative to the fabric, adjust the industrial camera 42 to a suitable position, and then the winding mechanism starts to wind. During the winding process, the industrial camera 42 takes pictures and detects its surface. The image will be uploaded to the computer, and the staff can zoom in to view its surface, and mark the places with surface defects. The roller 5 is detachable and can be equipped with rollers 5 of different sizes to adapt to fabrics of different widths. By providing a moving mechanism and a lifting mechanism, the device can adjust the position and height of the industrial camera 42 to achieve a better detection effect. By providing a detachable roller 5, the device can adapt to carbon fiber fabrics of different widths. It improves the flexibility and adaptability of the equipment and also reduces the production cost.

[0025] The moving mechanism includes a first motor 2, which is fixedly connected to a support block 11. A first rotating shaft 21 is provided at the output end of the first motor 2. A first gear 22 is fixedly connected to one side of the first rotating shaft 21. A second gear 23 is meshed and connected to one side of the first gear 22. A second motor 3 is fixedly connected to the other side of the support block 11. A second rotating shaft 31 is provided at the output end of the second motor 3. A third gear 32 is fixedly connected to one side of the second rotating shaft 31. A fourth gear 33 is meshed and connected to one side of the third gear 32. A first rocker 24 is fixedly connected to one side of the second gear 23. A second rocker 25 is connected to one side of the first rocker 24. A third rocker 34 is fixedly connected to one side of the fourth gear 33. A fourth rocker 35 is connected to one side of the third rocker 34. The fourth rocker 35 is connected to the second rocker 25. The bottoms of the fourth rocker 35 and the second rocker 25 are connected to a lifting mechanism; when the staff turns on the first motor 2, at this time the second motor 3 does not need to be turned on. The first motor 2 drives the first rotating shaft 21 at the output end to rotate, and the first gear 22 rotates, driving the meshed second gear 23 to rotate. In this way, the first rocker 24 rotates. The four rockers are connected. When the first rocker 24 rotates, it drives the other three rockers to move. In this way, the lifting mechanism will move, and the position of the industrial camera 42 at the bottom can be adjusted. Similarly, when the first motor 2 is turned off and the second motor 3 is turned on, at this time the second rotating shaft 31 rotates, driving the third gear 32 to rotate, and the meshed fourth gear 33 rotates, and the third rocker 34 rotates. In this way, the other three rockers will all rotate, but the direction in which the industrial camera 42 moves is different from the previous one. There is also when the two motors are turned on at the same time, driving the two rockers to rotate inward or outward at the same time. When rotating inward, the industrial camera 42 will be sent outwards, and when rotating outward, the industrial camera 42 will be retracted inwards. By providing a moving mechanism, it is convenient to adjust the position of the industrial camera 42 so as to adjust the best shooting angle.

[0026] A first vertical rod 26 is fixedly connected to the middle of the second gear 23. The first vertical rod 26 is rotatably connected to the inside of the support block 11. A second vertical rod 36 is fixedly connected to the middle of the fourth gear 33. The second vertical rod 36 is rotatably connected to the inside of the support block 11. The first vertical rod 26 is rotatably connected to the second vertical rod 36; the first vertical rod 26 mainly provides a certain supporting force for the second gear 23, and the second vertical rod 36 mainly provides a certain supporting force for the fourth gear 33. The first vertical rod 26 and the second vertical rod 36 are rotatably connected, so that the two vertical rods can rotate independently.

[0027] The first gear 22, the second gear 23, the third gear 32 and the fourth gear 33 are of equal size; in this way, the adjustment during movement is more stable.

[0028] The first rocker 24 and the second rocker 25 are hinged. The third rocker 34 and the fourth rocker 35 are hinged. The second rocker 25 and the fourth rocker 35 are hinged. A round rod 43 is fixedly connected to the tops of the second rocker 25 and the fourth rocker 35, and the round rod 43 corresponds to the inner top of the workbench 1. All four rockers are hinged to each other, making the adjustment more flexible. The inner top of the workbench 1 is made of magnetic material, and the round rod 43 is also made of magnetic material. The two are attracted to each other, can move relative to each other, and at the same time can ensure that the round rod 43 will not fall off. Therefore, the suction force provides stability.

[0029] The lifting mechanism includes a cylinder 4. The cylinder 4 is fixedly connected to the bottoms of the fourth rocker 35 and the second rocker 25. The output end of the cylinder 4 is connected to a piston rod 41, and the piston rod 41 is fixedly connected to an industrial camera 42. The lifting mechanism is fixedly connected to the bottom of the fourth rocker 35. When it is necessary to adjust the height of the industrial camera 42, the cylinder 4 is turned on. The piston rod 41 at the output end extends, and the industrial camera 42 descends. The piston rod 41 at the output end retracts, and the industrial camera 42 ascends. By providing a lifting mechanism, the relative height of the industrial camera 42 can be adjusted to obtain a better detection angle.

[0030] The winding mechanism includes a third motor 54. The third motor 54 is fixedly connected to a support leg 53. The output end of the third motor 54 is provided with a third rotating shaft 55. A cross bar 51 is fixedly connected to one side of the third rotating shaft 55. The cross bar 51 is rotatably connected to the support leg 53. A roller 5 is sleeved on the outside of the cross bar 51. First, the staff sleeves the roller 5 on the outside of the cross bar 51, and then fixes the support leg 53. Since the roller 5 can be disassembled, rollers 5 of different lengths can be placed on it. There is fabric on the roller 5, so that the device can be suitable for fabrics of different widths. Then the staff turns on the third motor 54, and the third rotating shaft 55 rotates, driving the cross bar 51 to rotate, and then the fabric starts to be wound. The fabric moves under the industrial camera 42, so that the industrial camera 42 can detect it. Facing fabrics of different widths, the relative position of the industrial camera 42 can be adjusted to achieve better detection.

[0031] Two strips 52 are fixedly connected to the outside of the cross bar 51, and two long grooves are formed inside the roller 5. The strips 52 correspond to the long grooves. When the cross bar 51 rotates, it drives the strips 52 to rotate. The strips 52 abut against the long grooves, and then the roller 5 can be driven to rotate. At the same time, the roller 5 is detachable, so there is no fixed connection between the roller 5 and the cross bar 51.
