The battery flipping mechanism 107 is installed on the second transmission channel 102. The battery flipping mechanism 107 includes a first drive motor 1071, a reversing cylinder 1072 and a suction cup 1073; the first drive motor 1071 is fixedly installed on the outside of the second transmission channel 102, and the first drive motor 1071 is used to drive the reversing cylinder 1072 to rotate around the axis. The reversing cylinder 1072 is located in the second transmission channel 102, and the rotating axis of the reversing cylinder 1072 is arranged in the horizontal direction to be perpendicular to the second transmission channel 102, and the suction cup 1073 is located on the outer circumference of the reversing cylinder 1072.

Compared with the prior art, the waste cylindrical lithium battery recycling equipment provided in this embodiment is that the lithium batteries in the lower hopper 103 enter the first transmission channel 101 and move to the first temporary storage box 104 driven by the first transmission mechanism 105. When the CCD camera 1061 detects that the electrode orientation of the lithium battery passing through meets the requirements, the push-out cylinder 1062 does not work, and the lithium battery will enter the first temporary storage box 104 driven by the first transmission mechanism 105; when the CCD camera 1061 detects that the electrode orientation of the lithium battery passing through is reversed (does not meet the requirements), the push-out cylinder 1062 works to push the lithium battery from the first transmission channel 101 to the second transmission channel 102, and the suction cup 1073 adsorbs the lithium battery on the reversing cylinder 1072, and the first driving motor 1071 drives the reversing cylinder 1072 to rotate, thereby turning the lithium battery 180°, thereby changing the orientation of the lithium battery; since the first transmission channel 101 and the second transmission channel 102 are connected at the end to form a ring channel, the lithium battery with the electrode orientation adjusted in the second transmission channel 102 will re-enter the first transmission channel 101; ultimately, it is ensured that the electrode orientation of the lithium batteries entering the first temporary storage box 104 remains consistent, realizing automated production and improving work efficiency.

In some embodiments, please refer to FIG. 1, FIG. 4 and FIG. 5, the first transmission mechanism 105 includes a first conveyor belt 1051 and a feeding mechanism 1052; the first conveyor belt 1051 and the feeding mechanism 1052 are sequentially arranged along the transmission direction and kept vertical, and the feeding mechanism 1052 includes a lifting cylinder 1053 and a push plate 1054, the lifting cylinder 1053 is located directly below the first transmission channel 101, and the push plate 1054 is fixedly installed on the top of the telescopic rod of the lifting cylinder 1053, and the push plate 1054 extends upward into the first transmission channel 101, and the push plate 1054 is stepped.

The first conveyor belt 1051 and the feeding mechanism 1052 are respectively located in two straight channels of the first transmission channel 101, so the transmission directions of the first conveyor belt 1051 and the feeding mechanism 1052 remain vertical. When the lithium battery is on the first conveyor belt 1051, the axial direction of the lithium battery is consistent with its transmission direction. When the lithium battery moves from the first conveyor belt 1051 to the feeding mechanism 1052, the axial direction of the lithium battery remains perpendicular to its transmission direction. The lifting cylinder 1053 is fixedly installed in the vertical direction just below the first transmission channel 101. The push plate 1054 is fixedly installed on the top of the telescopic rod of the lifting cylinder 1053. A plurality of support plates 1055 are arranged at intervals along the transmission direction of the lithium battery and the height gradually increases, so the push plate 1054 is stepped. A through hole is provided on the first transmission channel 101 for sliding cooperation with the support plate 1055. The lifting cylinder 1053 drives the push plate 1054 to reciprocate in the vertical direction, thereby realizing the transmission of the lithium battery and raising the height of the lithium battery. When the lithium battery with the electrode facing the opposite direction is pushed out of the cylinder 1062 and pushed to the second transmission channel 102, it will slide to the reversing cylinder 1072 under the action of gravity.

In some embodiments, please refer to FIG. 4 , a push-back cylinder 108 is installed at the corner of the second transmission channel 102, and the push-back cylinder 108 is directly opposite to the feed end of the first transmission channel 101. In this embodiment, the push-back cylinder 108 is fixedly installed in the horizontal direction on the outside of the corner of the second transmission channel 102. When the lithium battery moves to the corner of the second transmission channel 102, the push-back cylinder 108 applies a force toward the feed port of the first transmission channel 101 to the lithium battery, thereby pushing the lithium battery to the feed port of the first transmission channel 101, realizing the automatic transmission of the lithium battery between the second transmission channel 102 and the first transmission channel 101.

The discharge trough 1043 is opened on the outer circumference of the thumbwheel 1041, and the discharge trough 1043 runs through the entire thumbwheel 1041 along the axial direction of the thumbwheel 1041. The lithium batteries in the first temporary storage box 104 first enter the discharge trough 1043, and then are discharged from the discharge port of the first temporary storage box 104 as the thumbwheel 1041 rotates. Each discharge trough 1043 can only accommodate one lithium battery, so that the lithium batteries can be discharged from the first temporary storage box 104 in sequence.

The powder material contains magnetic powder and non-magnetic powder, and the two powders need to be recovered separately. The sorter 117 includes a first slide 1171, a second slide 1172, a magnetic separation cylinder 1173 and a second drive motor 1174. The first slide 1171 and the second slide 1172 are inclined, and the magnetic separation cylinder 1173 is located between the first slide 1171 and the second slide 1172. The magnetic separation cylinder 1173 is respectively slidably matched with the first slide 1171 and the second slide 1172 and kept parallel. A magnet or other device that can make the magnetic separation cylinder 1173 magnetic is installed inside the magnetic separation cylinder 1173. The second drive motor 1174 is used to drive the magnetic separation cylinder 1173 to rotate around the axis. The first slide 1171 corresponds to the discharge port of the pulverizer 116. The powdered material after being pulverized by the pulverizer 116 will enter the first slide 1171, and the non-magnetic powder will remain in the first slide 1171. The magnetic powder will be adsorbed on the magnetic separation cylinder 1173 under the action of magnetic force. When the magnetic separation cylinder 1173 rotates, the magnetic powder on the magnetic separation cylinder 1173 will move to one side of the second slide 1172 and detach from the magnetic separation cylinder 1173 under the action of the second slide 1172, so that the magnetic powder falls into the second slide 1172, and finally the magnetic powder and non-magnetic powder are recovered separately. The first slide 1171 is an arc structure, and the contact end of the first slide 1171 and the magnetic separation cylinder 1173 is the lowest point of the first slide 1171, so that the powdered material automatically moves to one side of the magnetic separation cylinder 1173.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
