Device for performing pre-delivery detection on mainboard by utilizing suction of sucker

The invention relates to the technical field of computer mainboards, and discloses a device for performing pre-delivery detection on a mainboard by utilizing suction of a sucker. The device comprisesa frame, wherein fixing rods are separately and fixedly arranged at the upper end and the lower end inside the frame; a fixing frame is slidably connected between the two fixing rods; a toothed plateis fixedly arranged at the front end of the fixing frame; uniformly distributed pulleys are rotatably connected to the fixing frame; sliding grooves corresponding to the pulleys are formed in the opposite surfaces of the fixing rods; and a rotating shaft is rotatably connected to the front end of the frame. According to the device for performing the pre-delivery detection on the mainboard by utilizing suction of the sucker, in the process of detecting the mainboard, a driving device is started to drive a belt pulley to rotate, the belt pulley drives a gear to rotate through the rotating shaft,and then the gear drives t
