[0034] A first robotic arm 8 is provided with a first suction cup 801, and the first robotic arm 8 can drive the first suction cup 801 to move to the clamping station and the sewing station.

[0035] The second robotic arm 9 is equipped with a needle suction cup 901, which can move the needle suction cup 901 to the material picking station, clamping station, sewing station and material feeding station.

[0036] This utility model provides an automatic sewing robot, including: a material picking platform 1, a clamping platform 2, a sewing device 6, a material feeding platform 7, a first robotic arm 8, and a second robotic arm 9. During sewing, the fabric to be sewn is placed on the material picking platform 1. The opening and closing mechanism 4 flips the cover plate 302 to a second position. The second robotic arm 9 uses a needle-type suction cup 901 to pick up the fabric to be sewn and place it on the base plate 301.

The second robotic arm 9 takes out the sewn fabric and places it on the material dispensing platform 7, completing the entire process. The whole process is automated, efficient, and collaborative, reducing manual intervention and improving production efficiency. By setting the locking member 303 and the locking part 305 to cooperate, the fabric can be pressed tightly to ensure that the fabric is flat and wrinkle-free during the sewing process, thus improving the sewing quality.

[0037] In a further embodiment of this invention, the opening and closing mechanism 4 includes a rotary drive device 401, an opening and closing bracket 402, and a second suction cup 403. The rotary drive device 401 is connected to the opening and closing bracket 402 and is used to drive the opening and closing bracket 402 to rotate. The second suction cup 403 is disposed on the opening and closing bracket 402, and the position of the second suction cup 403 corresponds to the position of the cover plate 302.

[0038] In this embodiment, the opening and closing mechanism 4 includes a rotary drive device 401, an opening and closing bracket 402, and a second suction cup 403. The rotary drive device 401 is a rotary cylinder, which controls the rotation of the opening and closing bracket 402. The opening and closing mechanism 4 uses the second suction cup 403 to attract the cover plate 302, thereby driving the cover plate 302 to open and close, ensuring precise alignment between the cover plate 302 and the base plate 301, further optimizing the fabric pressing effect and improving sewing quality.

[0042] In this embodiment, the locking member 303 is rotatably mounted on the base plate 301. A locking rod 306 is located at the top of the locking member 303. When locking, the locking member 303 is first in the unlocked state. Then, the opening and closing mechanism 4 drives the cover plate 302 to flip to the first position. At this time, the locking rod 306 precisely passes through the locking opening and is located on the upper part of the cover plate 302. The locking mechanism 5 drives the locking member 303 to the locked position, so that the locking rod 306 firmly locks the cover plate 302, ensuring its stability during sewing and preventing accidental movement, further improving sewing accuracy and safety. When unlocking, the locking member 303 is first rotated to the unlocked position, and then the opening and closing mechanism 4 flips the cover plate 302 to the second position. During the flipping process, the locking rod 306 can smoothly exit from the locking opening. The simple structure of the locking member 303 and the locking opening simplifies the operation process, reduces operational difficulty, and improves work efficiency.

[0045] In a further embodiment of this invention, the locking mechanism 5 includes a locking bracket 501, a locking drive device 502, a telescopic drive device 503, and a locking clamping block 504. The telescopic drive device 503 is disposed on the locking bracket 501 and is convectively connected to the locking drive device 502.

The locking drive device 502 is convectively connected to the locking clamping block 504 and is used to drive the locking clamping block 504 to rotate. The locking clamping block 504 is provided with a clamping groove 505.

[0046] In this embodiment, the locking mechanism 5 includes a locking bracket 501, a locking drive device 502, a telescopic drive device 503, and a locking clamp 504. The locking drive device 502 is a drive motor, and the telescopic drive device 503 is a drive cylinder. When locking or unlocking, the telescopic drive device 503 is activated, pushing the locking drive device 502 to a suitable position, so that the locking rod 306 of the locking member 303 is engaged in the clamping groove 505 of the locking clamp 504. The locking drive device 502 drives the locking clamp 504 to rotate, thereby driving the locking member 303 to rotate to the locked or unlocked position. Then, the telescopic drive device 503 is activated, driving the locking drive device 502 to reset, avoiding affecting the opening and closing of the cover. The automated design of the locking mechanism 5 not only reduces human error and ensures accurate locking, but also greatly improves the stability and reliability of the equipment operation, further guaranteeing the sewing quality.

[0047] In a further embodiment of this invention, the locking mechanism 5 further includes a bracket driving device 506, which is disposed on the clamping table 2 and is connected to the locking bracket 501 in a transmission manner. The bracket driving device 506 is used to drive the locking bracket 501 to rotate.

[0048] In this embodiment, the bracket driving device 506 is used to drive the locking bracket 501 to rotate. When locking or unlocking is required, the bracket driving device 506 is activated to precisely adjust the angle of the locking bracket 501 so that the locking clamp 504 is located above the locking member 303, thereby ensuring a smoother locking process. After locking or unlocking is completed, the bracket driving device 506 drives the locking bracket 501 to rotate, so that the locking driving device 502, the telescopic driving device 503 and the locking clamp 504 move away from the position above the locking member 303, avoiding interference with subsequent operations, further optimizing the equipment operation process and improving overall work efficiency.

[0049] In a further embodiment of this invention, the first robotic arm 8 is further provided with a suction cup bracket 802, and a plurality of first suction cups 801 are provided on the suction cup bracket 802, with the plurality of first suction cups 801 evenly distributed at the outer edge of the suction cup bracket 802.
