[0028] A tooling upper template 14 is installed at the end of the robot arm 3, and a plurality of upper template magnets 15 are arranged at the peripheral position of the lower surface of the tooling upper template 14. A tooling lower template 16 is arranged on the loading platform 2, and a plurality of lower template magnets 17 are arranged at the peripheral position of the upper surface of the tooling lower template 16. The upper template magnets 15 and the lower template magnets 17 correspond to each other, and an electromagnetic adsorption plate 18 is arranged in the middle of the tooling lower template 16; a positioning through hole is opened on the surface of the tooling lower template 16, and the positioning through hole cooperates with the telescopic shaft of the movable positioning cylinder 11.

[0029] Working principle:

[0030] In the initial state, the two tooling lower templates 16 are respectively located at the loading area and the unloading area at the front and rear ends of the upper surface of the loading platform 2. At this time, the two tooling lower templates 16 are magnetically fixed to the loading electromagnet 12 and the unloading electromagnet 13 through the electromagnetic adsorption plate 18, and the movable plate 10 is located in the unloading area.

[0031] During work, the staff lays the cloth to be sewn on the upper surface of the tooling lower template 16 located in the loading area at the front end of the loading platform 2, and then controls the robot arm 3 to drive the tooling upper template 14 to move to above the tooling lower template 16 in the loading area, so that the tooling upper template 14 and the tooling lower template 16 correspond to each other, and through the magnetic attraction of the upper template magnet 15 and the lower template magnet 17, the cloth is clamped between the tooling upper template 14 and the tooling lower template 16; at the same time, the loading electromagnet 12 and the unloading electromagnet 13 are both powered off, and then the telescopic shaft of the mobile positioning cylinder 11 is controlled to pass through the strip guide hole 5 and move upward to be inserted into the positioning through hole on the surface of the tooling upper template 14 located in the unloading area.

[0032] Afterwards, the mechanical arm 3 is controlled to drive the tooling upper template 14 and the tooling lower template 16 to move toward the sewing machine 4, so that the periphery of the fabric to be sewn corresponds to the sewing position of the sewing machine 4, and then the mechanical arm 3 is controlled to drive the tooling upper template 14 and the tooling lower template 16 to rotate along the periphery or according to the preset stitches, and then the periphery of the entire fabric to be sewn can be controlled to be sewn by the sewing machine 4. After the sewing is completed, the thread is cut by the thread cutting device. At the same time, by controlling the operation of the linear slide 7, the movable plate 10 is driven to move along the linear slide 7 toward the upper material area. In this embodiment, the linear slide 7 adopts a linear slide assembly with a screw drive, which includes a base and a slide seat arranged on the base, a servo motor is arranged at the end of the base, a ball screw is installed inside the base through a bearing, the driving end of the servo motor is connected to one end of the ball screw, the slide seat is threadedly connected to the ball screw through a threaded hole, and the movable plate 10 is fixedly installed above the slide seat. Therefore, by controlling the operation of the servo motor to drive the ball screw to rotate, the sliding seat can be used to drive the moving plate 10 to move along the axial direction of the ball screw, and then the moving plate 10 can be driven to move toward the upper material area. After that, the telescopic shaft of the mobile positioning cylinder 11 can be plugged into the tooling lower template 16 in the unloading area to drive the tooling lower template 16 in the unloading area to move toward the loading area; when it moves to the specified position, the telescopic shaft of the mobile positioning cylinder 11 is controlled to retract, and the loading electromagnet 12 is energized to magnetically fix the tooling lower template 16 again, so that the staff can lay the subsequent fabric to be sewn on the tooling lower template 16 in the loading area again.

[0033] Afterwards, the robot arm 3 is controlled to move the tooling upper template 14 and the tooling lower template 16 to the designated position of the unloading area, so that the tooling lower template 16 cooperates with the unloading electromagnet 13 again; the unloading electromagnet 13 is energized to magnetically fix the tooling lower template 16, and then the robot arm 3 is controlled to drive the tooling upper template 14 to move upward, so that the tooling upper template 14 is separated from the tooling lower template 16; the robot arm 3 returns to the initial state; after that, the above steps are repeated, so that the fabric to be sewn is sewn along the periphery again by the sewing machine 4, and the sewn fabric follows the tooling lower template 16 back to the loading area, and the staff takes it down and lays the fabric to be sewn again. Thereby, the work efficiency is effectively guaranteed, and the sewing quality of the fabric is also effectively improved.

[0034] Embodiment 2, as a further preferred embodiment of embodiment 1, the thread cutting device includes a telescopic cylinder 19 and pneumatic scissors 20, the tail end of the pneumatic scissors 20 is connected to the telescopic shaft of the telescopic cylinder 19, and the blade end of the pneumatic scissors 20 corresponds to the sewing end of the sewing machine 4.

[0035] After the fabric to be sewn is sewn, the telescopic shaft of the telescopic cylinder 19 can be controlled to extend, and then the blade end of the pneumatic scissors 20 can be driven to move to the sewing position, and then the blade of the pneumatic scissors 20 can be controlled to close, so as to realize the thread cutting work. After completion, the telescopic cylinder 19 and the pneumatic scissors 20 can be controlled to return to the initial state.

When the tooling lower template 16 is driven by the linear slide 7 to move toward the upper feeding area, the telescopic shaft of the loading positioning cylinder 21 can be controlled to extend to limit the position of the tooling lower template 16, thereby effectively ensuring that the tooling lower template 16 can be accurately moved to the specified position. Similarly, when the upper tooling template 14 and the lower tooling template 16 are moved to the specified position of the unloading area together by the robotic arm 3, the position of the lower tooling template 16 can be limited by controlling the extension of the telescopic shaft of the unloading positioning cylinder 22 to ensure that the lower tooling template 16 can correspond to the unloading electromagnet 13.

[0041] When the staff lays the cloth to be sewn on the lower template 16 of the tooling, the telescopic shaft of the lifting cylinder 28 can be controlled to extend to drive the entire lifting plate 25 to move upward, and then drive the positioning pin 27 to pass through the positioning through hole on the surface of the feeding platform 2 and extend upward, so that the corresponding positioning holes on the surface of the cloth and the small piece of cloth can be sleeved in the positioning pin 27, so that the placement position of the cloth to be sewn can be more accurate, thereby effectively ensuring the sewing yield of the cloth.
