According to the crossbeam device provided by the application, the PCB sucker is fixed below the crossbeam 1 and is used for adsorbing and loosening the PCB; in the application, a crossbeam 1 is driven by a single side, one end of the crossbeam is a movable end, the other end of the crossbeam is a driving end, and the driving end drives the movable end to lift together under the action of a driving air cylinder 9; specifically, the driving end is fixedly connected with the sliding block 5, the sliding block 5 is embedded in the sliding rail and is connected with the output end of the driving air cylinder 9, the triangular support 6 is arranged above the driving end in the beam 1, when the sliding block 5 drives the beam 1 to lift together, the acting force of the sliding block 5 on the beam 1 can be dispersed on the triangular support 6, the contact surface of the beam 1 and the sliding block 5 is prevented from being broken by a large force, meanwhile, the triangular support 6 can also increase the firmness of fixing the beam 1, further the lifting stability of the beam 1 is improved, and the service life of the beam device is prolonged; in order to ensure that the expansion end of crossbeam 1 steadily goes up and down under the drive end drives, the stationarity that crossbeam 1 goes up and down is further ensured to the expansion end and the sliding component sliding connection of crossbeam 1 in this application.

PCB sucking disc is connected to the absorption cylinder in this application, and under the absorption cylinder effect, PCB sucking disc adsorbs the PCB board or loosens the PCB board.

As a specific example, the sliding component is a cylindrical support rod 2, the cylindrical support rod 2 penetrates through the movable end of the cross beam 1, and the cylindrical support rod 2 is arranged parallel to the sliding rail. Crossbeam 1 adopts the unilateral drive in this application, and in the lift in-process crossbeam 1 needs whole lift, consequently, is connected to slider 5 and sliding component respectively with crossbeam 1's both ends on, and slider 5 can go up and down in the slide rail, and crossbeam 1's expansion end goes up and down along cylindric bracing piece 2 under the drive of drive end.

Its stroke of crossbeam 1 depends on the flexible degree that drives actuating cylinder 9 in the lift in-process, and is transporting the in-process of PCB board, and the height that rises of crossbeam 1 is limited, in order to ensure the steady lift of crossbeam 1, is provided with spacing bearing 3 at the top of cylindric bracing piece 2.
