Problems solved by technology
[0003] In the field of robot wall climbing, people try to use suction cups as a method of absorbing and climbing walls on walls with good surface finish and glass curtain walls. Since the suction cups need to be equipped with vacuum pumps or fans, the space and weight are relatively large, which brings inconvenience to the robot. Convenient, through the control of pipelines and electronic valves, the effect of negative pressure adsorption is reduced

Embodiment Construction
[0020] A suction cup for electrically generating negative pressure according to the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0021] Please refer to the attached Figure 1-2 , a sucker that electrically generates negative pressure, including a sucker 1, the bottom of the sucker 1 is covered with a diaphragm 2, the diaphragm 2 is flexible, and a pull rod 32 is connected to the inner side of the diaphragm 2, and the pull rod 32 passes through the inner cavity 12 of the sucker Penetrating above the suction cup 1, the upper end of the pull rod 32 is connected to the pull-up mechanism 5. When the suction cup 1 presses the diaphragm 2 close to the plane object, the pull-up mechanism 5 pulls the pull rod 32 to move upward so that the diaphragm 2 extends toward the inner cavity 12 Thereby a negative pressure is formed between the diaphragm 2 and the flat object.
[0022] In the above-mentioned embodiment, when the suc...

The invention relates to the technical field of wall-climbing robots and automation, and discloses a suction cup capable of electrically generating negative pressure, which comprises a suction cup body, the bottom of the suction cup body is coated with a flexible diaphragm, the inner side of the diaphragm is connected with a pull rod, the pull rod penetrates to the upper part of the suction cup body through an inner cavity of the suction cup body, and the upper end of the pull rod is connected to a lifting mechanism. When the suction cup tightly presses the diaphragm to be tightly attached to the plane object, the pull rod is pulled by the pull-up mechanism to move upwards so that the diaphragm can extend towards the inner cavity, and therefore negative pressure can be formed between the diaphragm and the plane object. According to the suction cup capable of electrically generating the negative pressure, in the using process, a vacuum pump or a draught fan does not need to be matched to serve as a vacuum and negative pressure source, the suction cup is controlled to suck and put down materials without a pipeline or an electronic valve, the vacuum degree and adsorption force of the suction cup are improved, and the service life of the suction cup is prolonged. Adsorption requirements of walls, glass curtain walls and the like with good surface smoothness can be met, and wall climbing design of the robot is facilitated.
Description
technical field [0001] The invention relates to the technical field of wall-climbing robots and automation, in particular to a suction cup for electrically generating negative pressure. Background technique [0002] Vacuum and negative pressure suction cups are widely used in intelligent manufacturing and automatic material grabbing. In use, a vacuum pump or fan is required as a vacuum and negative pressure source. Pipes and electronic valves are used to control the suction and release of materials by the suction cups. [0003] In the field of robot wall climbing, people try to use suction cups as a method of absorbing and climbing walls on walls with good surface finish and glass curtain walls. Since the suction cups need to be equipped with vacuum pumps or fans, the space and weight are relatively large, which brings inconvenience to the robot. Convenient, through the control of pipelines and electronic valves, the effect of negative pressure adsorption is reduced. Conte...
