The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

The embodiment of the application provides an electrostatic suction device. Referring to fig. 1 to 3, an electrostatic suction device 100 provided in an embodiment of the present application includes: a substrate 110, a first flexible clamping plate 120, a flexible electrode 130, and a second flexible clamping plate 140.

The flexible electrode 130 is sandwiched between the first and second flexible splints 120 and 140. In this way, the first and second flexible clamping plates 120 and 140 can be utilized as support backbones for the flexible electrode 130 in such a manner that the flexible electrode 130 is sandwiched between the first and second flexible clamping plates 120 and 140. In addition, the first and second flexible clamping plates 120 and 140 may be used to prevent the flexible electrode 130 from being damaged in such a manner that the flexible electrode 130 is clamped between the first and second flexible clamping plates 120 and 140.

The side of the first flexible clamping plate 120 facing away from the flexible electrode 130 is connected to the substrate 110. In the case where the electrostatic suction device 100 suctions the suction member 200, the second flexible clamping plate 140 abuts against the suction surface of the suction member 200, and the first flexible clamping plate 120, the flexible electrode 130, and the second flexible clamping plate 140 elastically deform, so that the surface of the second flexible clamping plate 140 facing the suction surface is deformed into a shape capable of being attached to the suction surface.

In this way, the manner in which the sheet-like object is manually scooped out by A4 paper in the related art can be replaced by the manner in which the sheet Zhang Dai suction member 200 is sucked by the electrostatic suction device 100. Since the electrostatic suction device 100 can directly suck the single Zhang Dai suction member 200 by means of electrostatic suction, the suction of the single Zhang Dai suction member 200 by means of the electrostatic suction device 100 does not require an operator to directly contact the suction member 200, and thus the risk of damage to the suction member 200 can be reduced.

The cover 150 and the substrate 110 enclose a receiving space, and the first flexible clamping plate 120, the flexible electrode 130, and the second flexible clamping plate 140 can be received in the receiving space. In this way, the first and second flexible clamping plates 120, 130 and 140 may be covered with the cover 150 to prevent the first and second flexible clamping plates 120, 130 and 140 from being damaged without using the electrostatic suction device 100.

Illustratively, the first light-transmitting area is located in a region near the middle of the second flexible clamping plate 140, so that in the case that the area of the to-be-adsorbed piece 200 is smaller, the to-be-adsorbed piece 200 and the region near the middle of the second flexible clamping plate 140 can be adsorbed, thereby facilitating the observation of the adsorption condition of the to-be-adsorbed piece 200 through the observation window 160.

It should be noted that, in other embodiments, the electrostatic suction device 100 may be mounted on a manipulator, and the manipulator may be used to drive the electrostatic suction device 100 to move so as to suck the to-be-sucked object 200. In the case where the electrostatic suction device 100 is mounted on a robot, the grip portion 170 may not be provided.

In some embodiments, the electrostatic extraction device 100 further includes a voltage regulation module, a controller, and a temperature and humidity data collector. Illustratively, the electrostatic extraction device 100 further includes a circuit board.

In some embodiments, the controller is configured to adjust the voltage applied to the flexible electrode 130 by the voltage adjustment module based on the weight parameter of the item to be suctioned, and the temperature parameter and the air humidity parameter acquired by the temperature and humidity data collector.

It should be noted that, for example, the air humidity parameter may be acquired by a dedicated humidity detection apparatus, and then the air humidity parameter acquired by the humidity detection apparatus may be transmitted to the controller.

In some embodiments, the electrostatic extraction device 100 may utilize a temperature and humidity data acquisition device to acquire temperature parameters and air humidity parameters of the location of use of the electrostatic extraction device 100. Illustratively, the electrostatic suction device 100 is provided with a temperature and humidity monitoring instrument at a place where the temperature and humidity monitoring instrument detects temperature parameters and air humidity parameters, which can be sent to a temperature and humidity data collector.

In general, in the related art, the electrostatic suction device applied to industrial use has a single corresponding use situation, and the voltage of the electrode of the electrostatic suction device is not basically required to be adjusted. In the field of cultural relics protection, the electrostatic adsorption force is too large, and the to-be-adsorbed piece 200 is not easy to fall down by itself after power failure. The electrostatic suction force is too small, and the to-be-suctioned member 200 may be accidentally separated from the electrostatic suction device 100 during movement with the electrostatic suction device 100. Thus, it is necessary to adjust the electrostatic attraction force of the electrostatic attraction device 100 by adjusting the voltage of the flexible electrode 130 of the electrostatic attraction device 100 as needed.

In some embodiments, the voltage of the flexible electrode 130 of the electrostatic suction device 100 may be obtained experimentally in various environments (different temperatures and humidities) and under various weights of the parts to be suctioned. And generating a data model based on the corresponding relation among the environment, the weight of the to-be-adsorbed piece and the voltage of the flexible electrode. Thus, during use of the electrostatic suction device 100, the controller may adjust the voltage applied by the voltage adjustment module to the flexible electrode 130 as desired based on the weight parameter, the temperature parameter, and the air humidity parameter of the piece to be sucked. The weight of the piece to be adsorbed may be obtained in advance by a weighing device, for example.

It should be noted that, for example, an "expert knowledge base" may be generated by an experimental manner, so that based on the weight parameter, the temperature parameter, and the air humidity parameter of the part to be sucked, a corresponding voltage is obtained from the "expert knowledge base", and the voltage applied to the flexible electrode 130 by the voltage adjustment module is adjusted as required.

For example, the correspondence relationship of the experimentally obtained environmental parameter, the weight parameter of the part to be adsorbed, and the voltage parameter of the flexible electrode may be determined based on a machine learning algorithm. Further, during use of the electrostatic suction device 100, the controller may adjust the voltage applied to the flexible electrode 130 by the voltage adjustment module as desired based on the correspondence relationship, the weight parameter of the member to be sucked, the temperature parameter, and the air humidity parameter.

In some embodiments, the electrostatic extraction device 100 further comprises a battery and a switch, the battery being electrically connected to the voltage regulation module through the switch. Illustratively, the battery is a rechargeable battery. During the process of sucking the to-be-sucked component 200 by the electrostatic sucking device 100 by the operator by holding the holding portion 170, the operator can press the switch so that the electrostatic sucking device 100 is in the working state, and thus the to-be-sucked component 200 can be sucked by the electrostatic force. In the case where the suctioned suction member 200 needs to be placed at a specified position, the operator can release the switch, so that the electrostatic force of the electrostatic suction device 100 disappears, and the suction member 200 is separated from the electrostatic suction device 100. So that the member to be adsorbed 200 can be placed at a specified position.

It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
