Conveying device

The invention relates to a conveying device. The conveying device comprises a guide rail for conveying trays and a tray pressing mechanism. The guide rail defines a length direction, a width direction and a height direction which are perpendicular to one another, the tray pressing mechanism comprises a tray pressing part and a driving part, and the tray pressing part is movably arranged relative to the guide rail so as to be close to and press the trays or loosen and get away from the trays. The driving part is connected to the tray pressing part and drives the tray pressing part to move, and the tray pressing part is movably arranged relative to the driving part. According to the conveying device, multi-directional adjustment of the tray pressing part is achieved, interference between the tray pressing part and other parts is avoided, the tray pressing part can better adapt to the position of the trays, meanwhile, the situation that the tray pressing part causes bias pressure to the driving part due to the i
