[0017] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings:

[0018] like Figures 1 to 2 As shown, the utility model discloses a circuit board feeding device, including multiple support rods 2 fixed on a frame 1, limit rods 4 are symmetrically fixed on the frame 1 on both sides above the support rods 2, a screw rod 3 is also provided on the frame 1 below the support rods 2, the screw rod 3 is driven to rotate by a motor 5, a push plate 6 threadedly connected to the screw rod 3 is provided on the screw rod 3, the ends of the limit rods 4 are fixed on a slide groove 9, a limit plate 8 is fixed on the side of the slide groove 9 away from the limit rod 4, a rotating cylinder 11 is fixed on the frame 1 below the limit plate 8, the output end of the rotating cylinder 11 is fixed with a positioning groove 12, and a positioning plate 13 is fixed at the bottom of the positioning groove 12, and a circuit board 7 pushing device is also fixed on the frame 1. The circuit boards 7 are neatly placed on the support rod 2. The two sides of the circuit boards 7 are limited by the limit rods 4. The motor 5 drives the screw rod 3 to rotate. Since the screw rod 3 is threadedly connected to the push plate 6, when the screw rod 3 rotates, the push plate 6 moves in the direction of the screw rod 3, and the push plate 6 pushes the circuit boards 7 to move. After the circuit board 7 farthest away from the push plate 6 passes the end of the support rod 2, the first circuit board 7 slides down from the slide groove 9. After passing through the slide groove 9, the circuit board 7 slides to the position of the positioning groove 12. The bottom of the circuit board 7 reaches the position of the positioning plate 13, and the rotating cylinder 11 is started. The circuit board 7 rotates along the positioning groove 12. In the horizontal state, the long-rod cylinder 14 is started, the piston rod on the long-rod cylinder 14 is extended, and the push block 15 moves toward the circuit board 7. After the push block 15 contacts the circuit board 7 between the two positioning plates 13, it pushes the circuit board 7 to move to the conveyor belt (not shown) to be supplied to the machine for processing. The piston rod on the long-rod cylinder 14 is shortened, and the push block 15 returns to the initial position. The rotary cylinder 11 is started again, and the positioning groove 12 returns to the vertical state. The motor 5 drives the screw rod 3 to rotate again, and the push plate 6 moves a distance of the thickness of the circuit board 7. The circuit board 7 slides into the positioning groove 12 again, and the operation is cyclic.
