A guide plate 23 is fixedly provided on one side of the feeding frame A21 and the feeding frame B22, and a collecting box A24 and a collecting box B25 are fixedly provided below the guide plate 23. A fixed groove 26 is opened at the frame opening of one side of the feeding frame A21 and the feeding frame B22, and a material blocking plate 27 is slidably provided in the fixed groove 26, and a telescopic cylinder B28 is fixedly provided on the material blocking plate 27, an air pump 8 is fixedly provided on the base 1, and an air supply pipe A81 fixedly connected to the telescopic cylinder A31 is fixedly provided at the output end of the air pump 8, an electronic three-way valve 82 is fixedly provided on the air supply pipe A81, and an air supply pipe B83 fixedly connected to the telescopic cylinder B28 is fixedly provided on the electronic three-way valve 82.

[0026] The negative battery in the loading frame A21 is grabbed into the grabbing frame 34 by the electromagnetic plate 36 in the grabbing frame 34, and then the grabbing frame 34 is driven to rotate by the motor 33 so that its opening direction is consistent with the loading frame B22, and the grabbing frame 34 is driven to connect with the loading frame B22 by the telescopic cylinder A31, and the battery is pushed into the loading frame B22 by the electric telescopic rod 35, so as to realize the sorting of the positive and negative poles of the battery, thereby reducing the workload of workers and improving their material sorting efficiency.

[0027] Figure 2 and 4 -5 shows a second embodiment, which mainly differs from the first embodiment in that: a guide groove 37 is provided on the base 1, a support rod 38 is slidably provided inside the guide groove 37, the end of the support rod 38 is fixedly connected to the U-shaped frame 32, a buffer spring 4 is fixedly provided inside the collection box A24 and the collection box B25, a buffer plate 5 is fixedly provided on the buffer spring 4, a protective rubber pad is fixedly provided on the buffer plate 5, a reset spring 6 is fixedly provided inside the fixed groove 26, and a filling plate 7 is fixedly provided on the reset spring 6.

[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0030] When in use, the batteries to be sorted are placed in the loading frame A21, and then the telescopic cylinder A31 drives the U-shaped frame 32 to move, so that the grabbing frame 34 in the U-shaped frame 32 contacts the loading frame A21, and then the electric telescopic rod 35 in the grabbing frame 34 drives the electromagnetic plate 36 at its end to contact the batteries in the loading frame A21. At this time, the electromagnetic plate 36 passes through, and uses the principle of like repels like and opposites attract to adsorb the battery with the negative end in contact with the electromagnetic plate 36 on the electromagnetic plate 36, and then the electric telescopic rod 35 drives the electromagnetic plate 36 back to the initial position, thereby moving the battery into the grabbing frame 34, and then the air pressure generated by the air pump 8 is transmitted to the telescopic cylinder A31 through the air pipe A81, so that it drives the grabbing frame 34 to separate from the loading frame A21, and at the same time the motor 33 is started, so that it drives the grabbing frame 34 to rotate, so that its opening direction changes. In order to be consistent with the opening direction of the loading frame B22, the telescopic cylinder A31 drives the U-shaped frame 32 to move so that the grabbing frame 34 contacts the loading frame B22, and then the electric telescopic rod 35 pushes the electromagnetic plate 36 to move so that the battery on the electromagnetic plate 36 moves into the loading frame B22. When the battery moves into the loading frame B22, the electromagnetic plate 36 is powered off, so that the battery falls into the loading frame B22, and then the telescopic cylinder A31 drives the U-shaped frame to separate from the loading frame B22. At the same time, the motor 33 drives the grabbing frame 34 back to the initial position, and then the air pressure generated by the air pump 8 is transmitted to the telescopic cylinder B28 through the air supply pipe B83 on the electronic three-way valve 82, so that it pushes the blocking plate 27 to move upward, and then the batteries in the loading frame A21 and the loading frame B22 fall into the collection box A24 and the collection box B25 through the guide plate 23, thereby realizing the positive and negative sorting of the batteries.
