[0002] Vacuum suction cup, also known as vacuum lifter or vacuum nozzle, is one of the actuators of vacuum equipment. It is widely used in automated production lines, medical, construction, papermaking industry, printing, glass and other industries. Its working principle is mainly to utilize the compressibility and liquefaction of air to generate adsorption force on the surface of objects through negative pressure, thereby achieving the grasping and transportation of objects.

[0003] A vacuum suction cup with application number CN202320435789.8, which is connected to an external vacuum suction machine, comprises: a first plate body, a second plate body, a first vacuum suction port, a plurality of second vacuum suction ports and a plurality of sealing components. Among them, a sealed cavity is provided between the first plate body and the second plate body; the first vacuum suction port is connected to the sealed cavity and is connected to the external vacuum suction machine; a plurality of second vacuum suction ports are respectively connected to the sealed cavity; a plurality of sealing components and a plurality of second vacuum suction ports correspond one to one, and the sealing components can seal the corresponding second vacuum suction ports. In the utility model, each adsorption station can be controlled individually, with good adsorption effect, convenient operation and low cost.

[0004] However, the device does not have a structure to clean the dust on the outside of the sheet when it adsorbs the sheet. If a large amount of dust adheres to the surface of the sheet, the adsorption force of the suction cup will be weakened during adsorption, and dust and dirt may fill the tiny gap between the suction cup and the surface of the workpiece, thereby destroying the sealing between the suction cup and the workpiece. This will reduce the vacuum generated by the suction cup, resulting in weakened adsorption force, and may even cause the workpiece to fall off during transportation, causing a safety hazard.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original vacuum suction cup structure. Utility Model Content

[0006] The purpose of the utility model is to provide a vacuum suction cup to solve the problem that the device proposed in the above background technology is not provided with a structure for cleaning the dust on the outside of the sheet when adsorbing the sheet. If a large amount of dust adheres to the surface of the sheet, the adsorption force of the suction cup will be weakened during adsorption, and dust and dirt may fill in the tiny gap between the suction cup and the surface of the workpiece, thereby destroying the sealing between the suction cup and the workpiece, which will reduce the vacuum generated by the suction cup, resulting in weakened adsorption force, and may even cause the workpiece to fall off during transportation, causing a safety hazard.

[0015] 1. Dust removal structure. When this structure adsorbs the sheet, the pad at the lower end of the fixed plate will contact the sheet before the rubber suction cup.

DETAILED DESCRIPTION

[0026] The adsorption assembly 4 includes a vacuum pump 401 and a controller 402. The vacuum pump 401 is fixedly installed on the outside of the hanger 1, and the controller 402 is fixedly installed on the outside of the vacuum pump 401; the adsorption assembly 4 also includes an air pipe 403 and a rubber suction cup 404.

The suspension plate 405 is equidistantly installed on the outside of the supporting beam 3, and the rubber suction cups 404 are symmetrically installed at the front and rear ends of the suspension plate 405;

[0027] When the sheet material needs to be transported, this structure first moves the sling 1 to the upper end of the sheet material through the suspension equipment, and the sling 1 moves downward by its own gravity or a driving device. When the sling 1 moves downward, the pad 503 at the lower end of the fixed plate 501 will contact the sheet material before the rubber suction cup 404. At this time, through the squeezing of the fixed plate 501 and the sheet material, the pad 503 compresses the telescopic spring 504 and moves toward the fixed plate 501. When the pad 503 moves toward the fixed plate 501, it compresses the elastic airbag 505 at the bottom of the fixed plate 501. The elastic airbag 505 is compressed, and the gas inside it is ejected through the air nozzle 507. The ejected gas acts on the outer surface of the sheet material, thereby blowing away the dust adhering to the outer surface of the sheet material, improving the cleanliness of the sheet material surface, and improving the adsorption capacity of the rubber suction cup 404.

[0028] Embodiment 2: Figure 1-Figure 3 , Figure 5The technical scheme shown in the utility model provides a technical scheme: a vacuum suction cup, which discloses: the dust removal component 5 includes a fixed plate 501, a sliding rod 502, a pad 503 and a telescopic spring 504, the fixed plate 501 is fixedly installed on the left and right sides of the supporting beam 3, and the sliding rod 502 runs through the inner side of the fixed plate 501, and the pad 503 is fixedly installed at the tail end of the sliding rod 502, and the telescopic spring 504 is connected between the pad 503 and the bottom of the fixed plate 501; the dust removal component 5 also includes an elastic airbag 505, a connecting pipe 506 and an air nozzle 507, the elastic airbag 505 is fixedly installed at the bottom of the fixed plate 501, and the outer side of the elastic airbag 505 is connected to the air nozzle 507 through the connecting pipe 506, and the air nozzle 507 is fixedly installed at the bottom of the fixed plate 501; the opening direction of the air nozzle 507 faces the rubber suction cup 404, and the air nozzle 507 is placed at an angle of 45° when viewed from the front;

The vacuum pump 401 will evacuate the inside of the rubber suction cup 404 through the air pipe 403, so that the inside of the rubber suction cup 404 is in a vacuum state and is tightly sucked against the sheet material. At this time, the sheet material can be transported to a suitable position through the suspension equipment, and the sheet material is lifted to the specified position. After the movement is completed, the controller 402 is turned off, the vacuum pump 401 stops working, the rubber suction cup 404 returns to normal pressure, and there is no suction on the sheet material. At this time, the vacuum lifter 1 is removed, and the lifting and transportation of the sheet material is completed.
