A supporting frame 10 is fixed in the mounting groove 2, more than two transition plates 11 are fixed at the upper end of the supporting frame 10, and a gap is arranged between every two adjacent transition plates 11. The upper end of the workbench 1 and the two sides of the installation groove 2 are respectively provided with a belt conveyor 12, and the upper end surface of the belt conveyor 12 is flush with the upper end surface of the transition plate 11. One of the belt conveyors 12 is used for feeding and the other belt conveyor 12 is used for discharging. The side plates 13 are respectively fixed on two sides of the belt conveyor 12, and the side plates 13 can prevent computer accessories from falling off in the conveying process.
A first air cylinder 14 is fixed at the upper end of the workbench 1, a piston rod of the first air cylinder 14 is fixed with a push plate 15, and the push plate 15 is arranged on one side of the support frame 10. A discharging channel 16 is arranged on one side of the support frame 10 far away from the push plate 15, and an infrared sensor 17 is fixed on the side wall of the discharging channel 16. And a second air cylinder 18 is fixed above the discharge channel 16, and the second air cylinder 18 can be fixed at the upper end of the workbench through a mounting frame. The piston rod of the second cylinder 18 is fixed with a baffle plate 19, and one end of the baffle plate 19 close to the push plate 15 and one end of the baffle plate 19 opposite to the side plate 13 are respectively fixed with a pressure plate 20.
