Because the sucking disc is divided into three sections, and independent interlayer is arranged between each section (not only the sucking disc is divided into three sections, but also the rear air path is divided into three sections, and each section corresponds to different sucking discs), when a large part is adsorbed, three paths are simultaneously vacuumized, and at the moment, the front parts of the three sections of sucking discs are blocked by the part, so that the part can be firmly adsorbed. When the medium parts are adsorbed, the three paths are vacuumized simultaneously, but at the moment, the part cannot block the largest section of sucker, the vacuum degree can not meet the requirement during vacuumizing, equipment at the rear monitors the vacuum degree and feeds the vacuum degree back to the peripheral control terminal, the peripheral control terminal closes the air path corresponding to the largest sucker, at the moment, the two sections of suckers are blocked, the vacuum degree reaches the standard, and the parts are firmly adsorbed. When small parts are adsorbed, three paths are vacuumized simultaneously, but at the moment, the parts cannot block the large two sections of suckers, the vacuum degree can not meet the requirement when vacuumized, equipment at the rear of the vacuum degree monitors the vacuum degree and feeds back the vacuum degree to the peripheral control terminal, the peripheral control terminal closes the air channel corresponding to the largest sucker, at the moment, the second section of sucker is not blocked, the vacuum degree does not reach the standard, the vacuum degree is fed back to the peripheral control terminal after 2 seconds, the peripheral control terminal closes the air channel corresponding to the second section of sucker, at the moment, the parts are firmly adsorbed, and thus the function of self-adapting parts with a certain size range is achieved.
