[0022] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example:

[0024] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0025] A defect detection device for jacquard curtain fabric production includes a base 1, with support platforms 2 fixedly connected to the front and rear sides of the top of the base 1, a conveying component 3 is provided on the top of the two groups of support platforms 2, a clamping component 4 is provided between the two groups of support platforms 2, and a detection component 5 is provided on the top of the base 1 and on the inner side of the clamping component 4.

[0026] Specifically, first place the base 1 at the designated position, put the jacquard fabric to be inspected into the conveying component 3, and convey the jacquard fabric through the conveying component 3. At this time, the support platform 2 supports the conveying component 3, and conveys the jacquard fabric to the clamping component 4. The jacquard fabric is clamped and limited by the clamping component 4, and then the jacquard fabric is inspected by the detection component 5. The clamping component 4 clamps the jacquard fabric to prevent the jacquard fabric from moving during detection and affecting the detection accuracy.

[0027] Among them, see Figure 1 and Figure 2 , a conveying assembly 3 is provided on the top of the two sets of support platforms 2;

[0028] The conveying component 3 is used to stably load and unload the fabric. The specific structure of the conveying component 3 is as follows:

[0029] The conveying assembly 3 includes a connecting plate 301, a connecting column 302, a buffer spring 303, a limit seat 304, an upper limit shaft 305, a lower limit shaft 306, a support plate 307 and a feed roller 308. The connecting plate 301 is fixedly connected to the top of the support platform 2. Two groups of connecting columns 302 are fixedly connected to the top of the support platform 2 and located below the connecting plate 301. The connecting plate 301 is connected to the limit seat 304 through three groups of buffer springs 303. The upper limit shaft 305 is rotatably connected to the interior of the limit seat 304. The lower limit shaft 306 is rotatably connected to the interior of the two groups of connecting columns 302 and located below the upper limit shaft 305. Two groups of support plates 307 are fixedly connected to the front of the support platform 2 and located below the lower limit shaft 306. The feed roller 308 is rotatably connected to the interior of the two groups of support plates 307.

[0030] Specifically, the jacquard fabric is loaded through the conveying component 3, and the support plate 307 supports the feed roller 308. The feed roller 308 guides the jacquard fabric to the bottom of the connecting plate 301, so that the jacquard fabric passes through the lower rolling shaft 306 between the two sets of connecting columns 302. At this time, the connecting plate 301 squeezes the rolling seat 304 through the buffer spring 303, and then squeezes the jacquard fabric through the rolling seat 304, and squeezes the jacquard fabric on the lower rolling shaft 306 through the upper rolling shaft 305. The jacquard fabric is rolled by squeezing the upper rolling shaft 305 and the lower rolling shaft 306.

[0031] Also, see Figure 1 and Figure 3 , a clamping assembly 4 is provided between the two sets of support platforms 2;

[0032] The clamping assembly 4 is used to firmly clamp the fabric. The specific structure of the clamping assembly 4 is as follows:

[0033] The clamping assembly 4 includes a bidirectional screw rod 401, a clamping seat 402, a lifting cylinder 403, an upper clamping plate 404, a lower clamping plate 405 and an anti-slip protrusion 406. The bidirectional screw rod 401 is rotatably connected between the support platforms 2. The outer side of the bidirectional screw rod 401 is threadedly connected to two groups of clamping seats 402. Two groups of lifting cylinders 403 are installed on the top of the two groups of clamping seats 402. The lifting cylinders 403 pass through the clamping seat 402 and are connected to the upper clamping plate 404. The lower clamping plate 405 is fixedly connected to the inside of the clamping seat 402 and located below the upper clamping plate 404. Several anti-slip protrusions 406 are fixedly connected to the inner sides of the upper clamping plate 404 and the lower clamping plate 405. A clamping motor is installed on the front of one group of support platforms 2 and at the position corresponding to the bidirectional screw rod 401. The driving shaft of the clamping motor passes through the support platform 2 and is fixedly connected to the bidirectional screw rod 401.

[0034] Specifically, the jacquard fabric is clamped and fixed by the clamping component 4, and the bidirectional screw rod 401 is driven by the clamping motor to rotate between the two groups of support platforms 2, and then the two groups of clamping seats 402 are driven to move closer to or away from each other by the bidirectional screw rod 401. After the two groups of clamping seats 402 are adjusted to a suitable distance, the jacquard fabric is conveyed to the inner side of the two groups of clamping seats 402 by the conveying component 3. At this time, the upper clamping plate 404 is driven to approach the lower clamping plate 405 by the lifting cylinder 403, and the jacquard fabric is clamped and limited by the upper clamping plate 404 and the lower clamping plate 405. The anti-slip protrusions 406 on the inner sides of the upper clamping plate 404 and the lower clamping plate 405 improve the clamping effect of the jacquard fabric.

[0035] Finally, see Figure 1 , a detection component 5 is provided on the top of the base 1 and located inside the clamping component 4;

[0036] The detection component 5 is used to perform multiple tests on the fabric. The specific structure of the detection component 5 is as follows:

[0037] The detection assembly 5 includes a first detection frame 501, a rotating frame 502, a second detection frame 503, a hydraulic cylinder 504, a detection table 505 and a friction ball 506. The first detection frame 501 is fixedly connected to the top of the base 1 and is located on the inner side of the clamping assembly 4. The interior of the first detection frame 501 is rotatably connected to the rotating frame 502 through a rotating shaft. A rough inspection camera is installed at the bottom of the rotating frame 502. A second detection frame 503 is provided on the inner side of the clamping assembly 4 and in front of the first detection frame 501. Two groups of hydraulic cylinders 504 are installed on the top of the second detection frame 503. Both groups of hydraulic cylinders 504 pass through the second detection frame 503 and are connected to the detection table 505. A detection motor is installed on the top of the detection table 505. The driving shaft of the detection motor passes through the detection table 505 and is connected to the friction ball 506. A third detection frame 507 is provided on the inner side of the clamping assembly 4 and in front of the second detection frame 503.

[0038] Specifically, the jacquard fabric in the clamping component 4 is inspected by the detection component 5, and the jacquard fabric is clamped and fixed by the clamping component 4. The rotating frame 502 in the first detection frame 501 rotates through the rotating shaft, so that the rough inspection camera inside the rotating frame 502 is always parallel to the jacquard fabric. The rough inspection camera is used to photograph and inspect the pattern on the surface of the jacquard fabric. Then, the hydraulic cylinder 504 on the top of the second detection frame 503 drives the detection platform 505 to move, and moves the detection platform 505 to the top of the jacquard fabric. At this time, the detection motor drives the friction ball 506 to move. The bottom of the inspection table 505 rotates, and then the friction ball 506 rotates on the surface of the jacquard fabric to perform wear resistance testing on the jacquard fabric. After that, the jacquard fabric enters the interior of the third inspection frame 507. A precision inspection camera is installed inside the third inspection frame 507. The precision inspection camera can rotate with the third inspection frame 507 through a rotating shaft, and then the jacquard fabric is precisely inspected by the precision inspection camera. At the same time, backlight sources are installed on the top of the base 1 and at positions corresponding to the first inspection frame 501 and the third inspection frame 507. The backlight source serves to enhance lighting during inspection.

[0039] In this embodiment, the implementation scenario is specifically as follows: in actual use, the base 1 is first placed at a designated position, and the jacquard fabric to be inspected is placed in the conveying component 3, and the jacquard fabric is conveyed by the conveying component 3. At this time, the support platform 2 supports the conveying component 3, and the conveying component 3 can avoid causing wrinkles on the surface of the jacquard fabric during transportation. The jacquard fabric is conveyed to the clamping component 4, and the jacquard fabric is clamped and limited by the clamping component 4, and then the jacquard fabric is inspected by the detection component 5. The clamping component 4 clamps the jacquard fabric to avoid the movement of the jacquard fabric during detection, which affects the detection accuracy. The detection component 5 is provided with two detection units near the positions of the two groups of conveying components 3. The rough inspection unit is near the feed end and the fine inspection unit is near the discharge end, so that the fabric being inspected can be magnified and small defects can be easily detected. The fault tolerance rate is low, the overall function is complete, and the practicality is strong. The detection unit can be attached to the surface of the jacquard fabric, thereby improving the detection accuracy. At the same time, the wear resistance of the fabric can also be tested through the detection component 5, which makes the detection diverse. Compared with the existing defect detection equipment for jacquard curtain fabric production, the utility model can improve the overall practicality of the defect detection equipment for jacquard curtain fabric production through design.
