[0002] The electrostatic adsorption device is used in the processing of embroidery fabrics to generate an electrostatic field on the surface of the fabric, making the embroidery fabric smoother and more stable during the processing, improving the fineness and efficiency of the embroidery. The electrostatic adsorption device can adsorb the fibers on the surface of the fabric, making the fabric less likely to move or wrinkle, which is conducive to the embroidery machine to perform accurate embroidery operations.

[0003] At present, the electrostatic adsorption device for embroidery fabric processing places the fabric on the workbench and controls the robotic arm to drive the electrostatic suction cup to adsorb the fibers on the surface of the fabric. However, the electrostatic suction cup is mostly fixed to the device with screws and nuts, and disassembly and assembly require the help of additional disassembly tools, which is more troublesome. In addition, since the processing process is relatively minor, most devices are not equipped with splints and cannot fix the fabric. However, the position of the fabric may still be shifted due to some external reasons. Therefore, an electrostatic adsorption device for embroidery fabric processing is proposed to solve the above problems. Utility Model Content

The two ends of the return spring a8 are respectively fixedly connected to the two ends of the return spring a8. The outer wall of the card block 9 is set to an inclined surface. In the process of inserting the cylindrical block 6 into the circular groove 18, the inner wall of the circular groove 18 squeezes the inclined surface of the card block 9 to squeeze the return spring a8 to retract. At the same time, the elastic force generated by the deformation of the return spring a8 gives the two groups of card blocks 9 a reverse thrust to reset them. The bottom of the card block 9 contacts the outer wall of the mounting seat 4, and the card block 9 buckles the outer wall of the mounting seat 4 to fix the electrostatic suction cup 5 on the mounting seat 4. When it needs to be removed, press the two groups of card blocks 9 inward and then pull the pull rod a7 outward to make the card block 9 completely retracted while resisting the inner wall of the cylindrical block 6 to prevent it from popping out. At this time, the electrostatic suction cup 5 can be removed, and the outer wall of the card block 9 contacts the inner wall of the cylindrical block 6.

[0030] Reference Figure 1 and Figure 3 The side wall of the workbench 1 is provided with a slide groove 10, and the inner wall of the slide groove 10 is slidably connected to the frame 11, and the inner wall of the frame 11 is elastically connected to the clamping plate 14 through the reset spring b12, one end of the reset spring b12 is fixedly connected to the inner wall of the frame 11, and the other end of the reset spring b12 is fixedly connected to the top of the clamping plate 14, and the clamping plate 14 can squeeze the reset spring b12 to move upward.

The bottom end of the pull rod b17 contacts the outer wall of the frame 11 to prevent the splint 14 from resetting. When the frame 11 is moved above the cloth, turn the pull rod b17 back to its original position.

At this time, the electrostatic suction cup 5 can be removed to facilitate the disassembly and maintenance of the electrostatic suction cup 5.
