The mounting buckle 30 is placed horizontally, and the distance sensor 31 is positioned between the mounting buckle 30 and the light-transmitting base plate 13 of the lifting seat 12. The top of the distance sensor 31 abuts against the bottom of the mounting buckle 30, and the bottom of the distance sensor 31 abuts against the transparent base plate 13.
[0083] Furthermore, the distance sensor 31, the seam sensor 33, and the selvage sensor 35 are used to transmit and receive light signals for sensing. The distance sensor 31 is used to measure the height of the fabric sewing control device 1 from the operating surface, so as to adjust the height of the fabric sewing control device 1 and to obtain the fabric thickness, thereby improving the accuracy of detection. The seam sensor 33 and the selvage sensor 35 are used to detect whether there is fabric, and then determine whether the fabric has been fed and the approximate position of the selvage. The camera 45 is used to capture real-time images of the selvage and upload them to the sewing machine mainboard for analysis and calculation.

[0089] Please see Figure 5A main motor 40 is fixed on the inner wall of the lifting seat 12 near the lifting slide rail 11.

The moving block 44 moves on the camera lead screw 43, and a camera 45 is fixedly connected to the moving block 44.
[0090] In one embodiment, the fabric sewing control device 1 is communicatively connected to the sewing machine motherboard, and performs calculations and analyses through the sewing machine motherboard to provide fabric sewing parameters.
[0091] In one embodiment, the position adjustment method of the fabric sewing control device 1 is as follows: after installing the fabric sewing control device 1 on the sewing machine, the front-to-back position of the fabric sewing control device 1 is adjusted through the slot on the fixed base 10, the up-and-down position of the lifting base 12 is adjusted by rotating the lifting knob 21, the left-to-right position of the seam sensor 33 is adjusted by rotating the first horizontal lead screw 381, and the left-to-right position of the sewing edge sensor 35 is adjusted by rotating the second horizontal lead screw 382. It should be noted that the above adjustment methods include manual, motor, cylinder, magnetic, and other power source-driven adjustments, and this application is not limited to these.
[0092] In one embodiment, the fabric sewing control device 1 further includes a cover, which is a detachable cover for protecting the internal parts of the lifting seat 12. The detachable cover improves the ease of installation and maintenance of the interior of the lifting seat.
[0093] In one embodiment, the fabric sewing control device 1 detects and controls fabric offset, including: after the device is powered on, the distance sensor 31, the thread sensor 33, and the selvage sensor 35 are activated. The first horizontal screw 381 is rotated according to a pre-set distance between the selvage and the thread. The movement of the first horizontal screw 381 causes the first sliding buckle 341 and the thread sensor 33 to move, aligning the thread sensor 33 with the needle, i.e., aligning it with the thread. The second horizontal screw 382 is rotated, causing it to move. The movement of the second horizontal screw 382 causes the second sliding buckle 342 and the selvage sensor 35 to move, aligning the selvage sensor with a predetermined standard selvage. When the first sliding buckle 341 and the second sliding buckle 342 move, the pressure of the first spring 361 on the first pressure sensor 371 and the pressure of the second spring 362 on the second pressure sensor 372 are different due to the different compression distances of the first spring 361 and the second spring 362. The position of the seam sensor 33 is obtained based on the pressure change of the first spring 361 on the first pressure sensor 371, and the position of the selvage sensor 35 is obtained based on the pressure change of the second spring 362 on the second pressure sensor 372. The position information is displayed on the sewing machine, thereby enabling the seam sensor 33 and the selvage sensor 35 to accurately align the seam and the selvage.
[0094] The distance sensor 31 detects the height of the fabric sewing control device 1 on the base plate. Based on this height, the lifting knob 21 is rotated, causing the lifting screw 23 to rotate and rise within the lifting sleeve 22. Simultaneously, the lifting slider 14 slides within the lifting rail 11, raising and lowering the lifting seat 12 accordingly. This adjusts the height of the lifting seat 12, ensuring that the seam sensor 33 and the selvage sensor 35 within the lifting seat 12 also move with it, thus maintaining the detection accuracy of the seam sensor 33 and the selvage sensor 35 within the specified range. After the fabric is fed in, the distance sensor 31 also detects the fabric thickness, providing data for subsequent sewing. When the sewing sensor 33 detects the fabric, the automatic control camera 45 is activated. The fabric sewing control device 1 can also be used in conjunction with an automatic machine, utilizing the robotic arm within the machine to adjust the position and angle of the fabric selvage.
[0095] In summary, the fabric sewing control device of this application utilizes a distance sensor within the lifting base to detect the device height and fabric thickness. It uses a thread sensor, selvage sensor, and camera to detect fabric position and whether the fabric has deviated. Simultaneously, it uses a lifting screw and lifting knob, aided by a lifting slider and lifting rail, to raise and lower the lifting base, adjusting the positions of the sensors and camera within the lifting base. A horizontal screw within the lifting base moves the thread sensor and selvage sensor left and right. A main motor, via gears, moves the camera on the camera screw. The positions of the thread sensor and selvage sensor are determined by a pressure sensor and a spring. This fabric sewing control device achieves precise calculation of fabric deviation and uses a robotic arm to adjust the fabric feed based on the precise fabric deviation, thereby achieving precise fabric sewing.
