However, the present invention is not limited to these embodiments. Specific details, such as particular configurations and components, are provided in the following description merely to aid in a comprehensive understanding of the embodiments of the present invention. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other.

[0045] like Figure 1-3 As shown, this embodiment provides a sewing quality detection device, which includes a first detection device 100, a second detection device 200, a display device 300, an alarm device 400, and a main controller.

[0046] The first detection device 100 is installed in the sewing process of the sewing unit to detect poor sewing quality in this process. The first detection device 100 includes a piece acquisition frame 110, a sewing worktable 120, a piece acquisition device 130, a needle movement module 140, a sewing acquisition device 150, and a first controller 160. The piece acquisition device 130 is installed on the piece acquisition frame 110 and is located above the sewing worktable 120. The sewing unit is placed on the sewing worktable 120, and the piece acquisition device 130 is used to acquire image information of the sewing unit to be sewn. The needle movement module 140 is installed above the sewing worktable 120, and the sewing acquisition device 150 is installed on one side of the needle movement module 140 to acquire sewing data information. The first controller 160 is connected to the piece acquisition device 130, the needle movement module 140, and the sewing acquisition device 150 for data interaction.

[0047] The second detection device 200 is used to detect poor quality after the sewing unit is finished. The second detection device 200 includes a finished product placement rack 210, a finished product collection rack 220, a finished product collection device 230, and a second controller 240. The finished product placement rack 210 is provided with finished product collection racks 220 on both sides. The finished product collection device 230 and the second controller 240 are provided on the finished product collection racks 220. The finished product collection device 230 is used to collect finished product image information. The second controller 240 is connected to the finished product collection device 230 for data interaction.

[0048] The display device 300 is connected to the first controller 160 and the second controller 240 for data interaction; the alarm device 400 includes a buzzer 410 and a signal light 420 installed on the piece collection rack 110 and the finished product collection rack 220. The buzzer 410 and the signal light 420 on the piece collection rack 110 are electrically connected to the first controller 160, and the buzzer 410 and the signal light 420 on the finished product collection rack 220 are electrically connected to the second controller 240; the first controller 160 and the second controller 240 are connected to the main controller for data interaction.

[0049] The first controller 160 includes an image storage module, an image processing module, a statistics module, and a comparison detection module. The image storage module stores template image information of the sewing unit and data information of the sewing template. The statistics module is used to collect sewing data information collected by the sewing acquisition device 150. The image processing module converts and processes the sewing unit image information collected by the fabric acquisition device 130 and the sewing data information collected by the sewing acquisition device 150. The comparison detection module compares the sewing unit image information obtained by the image processing module with the sewing unit template image information stored in the image storage module, and compares the sewing data information collected by the sewing acquisition device 150 and the statistics module with the sewing template data information.

[0050] Specifically, the piece acquisition device 130, the sewing acquisition device 150, and the finished product acquisition device 230 all include acquisition cameras. The sewing unit image information acquired by the piece acquisition camera includes sewing unit size information, sewing unit style information, and sewing unit color information. The sewing data information collected by the statistics module includes sewing stitch count data, skipped stitch information, and backstitch count data. At the same time, the sewing unit template image information stored in the image storage module of the first controller 160 also includes template size information, template style information, and template color information, which is the information that meets the qualified standards and is correct, and serves as a basis for comparison. The sewing template data information stored in the image storage module includes the allowable error value of the number of sewing stitches within a sewing distance at one end, the allowable number of skipped stitches, and the allowable number of backstitches, which are also used as a basis for comparison. Therefore, after the fabric piece acquisition camera completes its data collection, the comparison and detection module determines that the size, style, or color of the sewing unit differs from the template (e.g., larger or smaller size, incorrect cutting style, incorrect color). In this case, the buzzer 410 sounds an alarm, and the indicator light 420 flashes, indicating that the sewing unit does not meet the requirements. Pre-testing the sewing unit before sewing prevents substandard units from entering the sewing process, thus avoiding wasted time and materials and ensuring sewing quality. Furthermore, the sewing unit may have been contaminated with oil during previous processes, resulting in uneven color. The fabric piece acquisition camera can also detect oil-stained sewing units. After the sewing acquisition camera completes its data collection and the statistics module completes its statistics, the comparison and detection module compares the data. If the number of stitches sewn by the sewing unit exceeds the allowable error value, the number of skipped stitches, or the number of reverse stitches, the buzzer 410 will sound an alarm and the indicator light 420 will flash, indicating that the sewing unit does not meet the qualification requirements. During the sewing process, the sewing quality within the sewing distance during the detection stage will be checked to avoid continuing the sewing process due to unqualified sewing, thus saving time and materials and ensuring sewing quality.

[0051] The second controller 240 includes an image storage module, an image processing module, and a comparison detection module; the image storage module is used to store the finished product template image information after sewing is completed; the image processing module is used to convert and process the finished product image information acquired by the finished product acquisition device 230; and the comparison detection module is used to compare the finished product image information obtained by the image processing module with the finished product template image information stored in the image storage module.

[0052] Specifically, the finished product image information captured by the finished product acquisition camera includes finished product size information, finished product style information, and finished product color information; at the same time, the finished product template image information stored in the image storage module of the second controller 240 also includes finished product template size information, finished product template style information, and finished product template color information, which are the information that meets the qualification standards and is correct, and serve as the basis for comparison; therefore, when the finished product acquisition camera completes the acquisition, and the comparison and detection module compares it, if the size, style, and color of the sewn product are different from the template (such as larger or smaller size, incorrect cutting style, or incorrect color), the buzzer 410 will sound an alarm and the signal light 420 will flash, indicating that the sewn finished product does not meet the qualification requirements. After the sewing is completed, the quality of the sewing unit will be further inspected to ensure product quality and prevent unqualified sewn products from being shipped out.

[0053] In this embodiment, the finished product placement rack 210 includes a support frame 211 and a fixing plate 212. The fixing plate 212 is disposed above the support frame 211, and the bottom of the support frame 211 is slidably disposed above the slide rail 250. The two fixing plates 212 are disposed opposite to each other and can be disassembled. The fixing plates 212 are arranged vertically and are parallel to the slide rail 250. The fixing plates 212 are made of transparent material. During testing, the finished product is laid between the two fixing plates 212 and slid between the two finished product collection devices 230 via the support frame 211. Then, the finished product collection devices 230 are driven to move up and down along the finished product collection rack 220 to achieve comprehensive collection of both sides of the sewn product.

[0054] like Figure 4 The above-mentioned sewing quality inspection device is shown as a detection method, which includes the following steps:

[0055] S1. The cut sewing units are transported to the designated position on the sewing workbench 120 by the conveying mechanism of the sewing production line.

[0058] S4. Compare the sewing unit image information processed in step S3 with the sewing unit template image information stored in the image storage module to determine whether the sewing unit image information and the template image information are within the acceptable error range. If they are acceptable, continue to the next process. If they are unacceptable, the signal light 420 flashes and the buzzer 410 sounds an alarm to remove the unacceptable product.

[0059] S5. Move the needle moving module 140 to the sewing start point of the qualified sewing unit obtained in step S4, start the sewing work, and at the same time, the sewing acquisition device 150 collects the corresponding sewing data information, and the statistics module collects the corresponding sewing data information.

[0060] S6. The image processing module converts and processes the sewing data information collected by the sewing acquisition device 150.

[0061] S7. Compare the processed and statistically obtained sewing data information with the stored sewing template data information to determine whether the sewing data information and the sewing template data information are within the acceptable error range. If they are acceptable, continue to the next process. If they are unacceptable, the signal light 420 flashes and the buzzer 410 sounds an alarm to remove the unacceptable product. The display device 300 can also display the position of the unacceptable product that does not meet the acceptance requirements.

[0062] S8. The finished product obtained in step S7 is laid flat between the two fixed plates 212 of the finished product placement rack 210 and the fixed plates 212 are fixed. The finished product placement rack 210 is moved between the finished product collection racks 220 on both sides and the finished product collection device 230 is lifted and moved to collect the finished product.

[0063] S9. Convert and process the finished product image information collected by the finished product acquisition device 230;

[0064] S10.
