| Zusammenfassung: | The utility model relates to the field of tooling jigs, and particularly discloses a vacuum operation system capable of preventing piece skipping, which comprises a first vacuum cavity and an adsorption jig positioned in the first vacuum cavity, and a second vacuum cavity used for adsorbing workpieces is formed in the adsorption jig; the device is characterized in that the second vacuum cavity and the first vacuum cavity are communicated through at least one pressure release valve, the pressure release valve is configured to be opened when the pressure in the second vacuum cavity is larger than that in the first vacuum cavity, and the first vacuum cavity and the second vacuum cavity are communicated to enable the pressure of the second vacuum cavity to be reduced so as to prevent piece jumping; and when the pressure in the second vacuum cavity is smaller than or equal to that in the first vacuum cavity, the second vacuum cavity is closed, and the first vacuum cavity and the second vacuum cavity are isolated, |
