[0027] Guide rails 4 are fixed on both ends of the support plate 2. The left guide rail 4 is above the right guide rail 4. A sorting mechanism 5 is provided between the two guide rails 4. A longitudinal plate 6 is fixedly installed on the lower end of the left guide rail 4. A vibration mechanism 7 is fixed on the inner side of the longitudinal plate 6. The vibration mechanism 7 drives the sorting mechanism 5 to vibrate relative to the two guide rails 4.

[0028] The sorting mechanism 5 includes two clamping plates 501 and a step plate 502. The step plate 502 is a structure with steps going downward from left to right. The step plate 502 is located between the two clamping plates 501 and fixed thereto. The two ends of the step plate 502 are respectively inserted into the left and right guide rails 4 and slide relative to them. The end shape of the step plate 502 matches the internal shape of the guide rail 4. The two ends of the clamping plate 501 are respectively clamped outside the two guide rails 4 and slide relative to them. The shape of the clamping plate 501 matches the guide rail 4. The upper end of the clamping plate 501 is provided with a placement groove 503 corresponding to the plane position of the step plate 502. A magnetic bar 504 is mounted at the position corresponding to the placement slot 503. The magnetic bar 504 is made of a strong magnetic material or an electromagnet is used to provide magnetic force. The front and rear ends of the magnetic bar 504 are mounted in the placement slot 503 and magnetically attract the card plate 501. The outer surface of the magnetic bar 504 is covered with a penetration sleeve 505, and the magnetic force can pass through the penetration sleeve 505.
