As shown in fig. 2, an insulating cover sheet and an insulating base sheet are disposed above and below the positive electrode sheet 41 to protect the electrode sheet 4, and during the adsorption operation, the electrostatic generator 1 supplies power to the electrode sheet 4 to generate an electrostatic field between the positive electrode sheet 41 and the negative electrode sheet 42, which polarizes charges on the workpiece adsorption surface of the insulating cover sheet to generate an electrostatic force for adsorbing the workpiece. The insulating substrate and the insulating cover plate in this embodiment are PI insulating sheets 3, and in other embodiments, the insulating substrate and the insulating cover plate may also be made of PVC, plexiglass or polycarbonate.

It should be noted that, after the positive plate 41 and the negative plate 42 are connected to the electrostatic generator 1, when the electrostatic adsorption component generates an adsorption force, a large amount of positive charges are also gathered on the metal conductor 53 and the pointer 52, and the electrostatic adsorption force is positively correlated to the number of the gathered positive charges, a repulsive force is generated between the positive charges on the metal conductor 53 and the pointer 52, the repulsive force drives the pointer 52 to rotate in the field intensity indication region, and the rotation angle is positively correlated to the number of the positive charges on the metal conductor 53 and the pointer 52, so that the magnitude of the electrostatic adsorption force on the electrostatic adsorption component can be simply and efficiently judged through the scale indicated on the field intensity scale line in the field intensity indication region by the pointer 52.
