Vacuum adsorption type conveying device

The utility model particularly relates to a vacuum adsorption type conveying device. The device comprises a conveying belt, a base, a power mechanism and a vacuumizing device, a cavity is formed in the base, grooves, first adsorption holes and second adsorption holes are formed in the upper surface of the cavity, the two grooves are formed in the conveying direction of the conveying belt side by side, and the first adsorption holes are used for communicating the grooves with the cavity; the second adsorption holes are located between the two rows of grooves and used for adsorbing the middle of the conveying belt. The conveying belt is wound on the base, covers the groove and is provided with a third adsorption hole, and the third adsorption hole corresponds to the groove and is used for adsorbing the conveyed objects; the power mechanism is used for providing power for the conveying belt, and the vacuumizing device is used for adjusting vacuum intensity. According to the device, the belt is adsorbed through t
