The first electrode 13A, the first electrode 140 and the second electrode 150 can respectively present different voltage levels (positive level, zero level and negative level), respectively, thereby forming a three-phase voltage to induce polarity The opposite is static, thus creating an electrostatic attraction. In the present embodiment, the phases of the voltage waveform periods of the electrodes 130, 140, and 15 are, for example, 120 degrees out of phase with each other to form a three-phase voltage. For example, when the electrodes 130, 140, and 150 are located in the interval a, the first electrode 13 is a positive voltage, the second electrode 140 is a negative voltage, and the third electrode 15 is at a zero level; When the electrodes 130, 140, and 150 are located in the interval b, the first electrode 130 has a positive voltage, the second electrode 14 has a zero level, and the third electrode 15 has a negative voltage. Therefore, when the electrodes 〇3, 140, and 150 are electrically turned on, the electrodes 130, 140, and 150 can sequentially change the level of the voltage toward a predetermined direction to form an electrostatic attraction toward the predetermined direction. As shown in FIG. 1 and FIG. 2, the insulating layers 180 may be formed on the electrodes 13A, 140, and 150, and the insulating layer 180 may be adhered to the electrodes 130, 140, for example, by bonding a thin insulating plate or an insulating film. 150, to prevent the object 200 from being directly exposed to the electrodes 130, 140. and .150, reducing static damage to the object 200927625 200. When the first electrode 130, the second electrode 140, and the third electrode 150 are electrically connected (voltage is connected), the surfaces of the electrodes 130, 140, and 150 are sequentially alternately formed with electric fields of opposite polarities, thereby generating The electrostatic attraction causes the article 200 to be adsorbed on the transport substrate 120. Furthermore, the first electrode 130, the second electrode 140, and the third electrode 150 are electrically connected to a control unit (for example, a computer system or a programmable control chip) to control the electrodes 130, 140, and 150, respectively. The electrical conduction is sequentially conducted, so that the electrostatic attractive force is gradually formed on the transport substrate 120 in a predetermined direction, and further, the attracting object 200 travels in a predetermined direction. It should be noted that, in this embodiment, the electrodes 130, 140, and 150 form a three-phase voltage change to generate electrostatic attraction, but are not limited thereto, and those skilled in the art may choose to make two-phase or multi-phase. The voltage changes to create an electrostatic attraction. As shown in FIG. 1 and FIG. 2, the air injection hole 160 of the embodiment is formed on the transport substrate 120, and the air injection hole 160 is connected to, for example, an electric air pump (not shown), so that the air injection hole 160 can be The gas φ (for example, an inert gas) is ejected toward the object 200, and thus the air pressure is applied to the object 200. Therefore, when the object 200 is transported on the transport substrate 120, the object 200 can pass through the first electrode 130 and the second electrode 140. The electrostatic attraction force generated by the third electrode 150 is adsorbed on the transport substrate 120 while maintaining a predetermined distance d between the object 200 and the transport substrate 120 by the air pressure thrust acting by the gas jet hole 160. The air vents 160 are provided with a buffer space 161 for allowing gas to pass into the buffer space 161 and then ejected by the gas vent 160 to relieve the pressure of the gas and prevent the air pressure from being excessively damaged to damage the transport substrate 120 or the object 200. 〇9 200927625 The side electrode group 170 of the present embodiment is disposed on both sides of the transport substrate 120 for further forming electrostatic adsorption force on both sides of the transport substrate 120, thereby ensuring that the object 200 moves on a predetermined track without being detached. The substrate 120 is transported, and the stability of the article 200 during transport on the transport substrate 120 can be improved. It should be noted that the electrostatic attraction force and the air pressure thrust can be adjusted according to the weight of the object 200, so that the object 200 can form a resultant force balance in the vertical direction and can maintain a predetermined distance from the transport substrate 120. . Referring to Figures 3A and 3B, a side view of a delivery device in accordance with a first embodiment of the present invention is shown. When the transport device 100 of the present embodiment transports the object 200, the object 200 is electrostatically adsorbed on the transport substrate 120, and is maintained at a predetermined distance d from the transport substrate 120 by the air pressure thrust of the air vent 160, thereby forming a non-contact type. Delivery. When the object 200 is transported on the transport substrate 120, at this time, the first electrode 130, the second electrode 140, and the third electrode 150 corresponding to the lower portion of the object 200 can move the electrostatic attracting member 200 in a predetermined direction. Therefore, the conveying device 100 of the embodiment can perform the non-contact object conveying by the electrostatic attraction force and the air pressure thrust, so as to prevent the object 200 from being scratched on the surface of the object 200 during the conveying process, and can be reduced. Dust or particles are generated, thereby facilitating the maintenance of the cleanliness of the article 200. In addition, since the object 200 is electrostatically adsorbed on the transport substrate 120, the object 200 can be smoothly transported to avoid the occurrence of object disturbance and shaking, so that it is convenient to perform other operations on the object 200 during transport. Moreover, since the object 200 is actuated by electrostatic attraction, the movement of the animal member 200 can be controlled by controlling the electrical conduction of the electrodes 121, 140 and 150 of the 200927625, and the delivery accuracy is high. Positioning. Referring to Figure 4, there is shown a side view of a delivery device in accordance with a second embodiment of the present invention. Only the differences between the embodiment and the first embodiment will be described below, and the details are not described herein again. Compared with the first embodiment, the air injection hole 36 of the conveying device 1 of the second embodiment corresponds to the object 200 for performing a partial jet action, that is, only the gas injection hole 360 directly below the object 2 is There is a jet action to maintain a predetermined distance d between the object 2 and the substrate 120, wherein the gas jet 360 can control the jet action by a control unit, such as a computer system or a programmable wafer. Therefore, the conveying device 10 of the second embodiment can further save the amount of use of the gas 'and reduce unnecessary airflow disturbance on the conveying substrate 12'. Referring to Figure 5, there is shown a side view of a delivery device in accordance with a third embodiment of the present invention. Only the differences between the embodiment and the first embodiment will be described below, and the details are not described herein again. Compared with the first embodiment, the transport substrate 420 of the third embodiment is formed of a gas permeable ceramic material to form a permeable ceramic substrate, and the gas permeable ceramic material has a gas permeability, so that the surface of the substrate 420 is naturally transported. A minute air vent 460 is formed thereon. Therefore, when the object 200 is transported, non-contact object transport can be performed by both electrostatic attraction and air pressure thrust. It can be seen from the above embodiments of the present invention that the conveying device of the present invention can perform non-contact conveying of articles to avoid scratching or damage of the articles during transportation, and can reduce dust or particles to maintain good cleanliness. In addition, the conveying device of the present invention can smoothly transport the articles, thereby facilitating other operations on the articles during the transportation process.
