[0050] The present invention includes a sorting method for a cylindrical battery voltage testing and sorting machine, which includes the following steps: S1, a material tray 103 is moved along a chute 102 to the bottom of an adjacent material transfer mechanism 2, and the cylindrical batteries inside the material tray 103 are transferred to the inner side of a placement plate 305 of a flipping mechanism 3 through the material transfer mechanism 2.

The sorting method of the cylindrical battery voltage test sorting machine according to any one of claims 1 to 8, characterized in that: The method comprises the following steps: S1, the material tray (103) moves along the slide groove (102) to the bottom of the adjacent material transfer mechanism (2), and the cylindrical batteries inside the material tray (103) are transferred to the inner side of the placement plate (305) of the flipping mechanism (3) through the material transfer mechanism (2); S2, the servo motor (308) causes the placement plate (305) to rotate through the meshing action between the rotating gear (309) and the driven gear plate (306), so that the cylindrical battery is rotated from a vertical state to a horizontal state, and then the first hydraulic cylinder (304) works to cause the mounting frame (303) to move along the movable groove (302); S3, the material transfer mechanism (2) at the middle position operates so that the first electric push rod (204) pushes the suction cup (205) to absorb the cylindrical battery, and then the movable seat (203) moves along the slide rail (202) to transfer the cylindrical battery on the top of the placement plate (305) to the inner side of the adjacent conveyor belt (104); S4, conveying the cylindrical batteries to the top of the voltage testing device (4) via the conveyor belt (104), and testing the open circuit voltage and load voltage of the cylindrical batteries via the voltage testing device (4) for sorting the cylindrical batteries; S5, the cylindrical batteries that have passed the inspection are transferred through the last material transfer mechanism (2) so as to be transferred from one conveyor belt (104) to the inner side of another conveyor belt (104), and the qualified cylindrical batteries are transported through the conveyor belt (104); S6, the insulating sheet feeding mechanism (5) operates so that the insulating sheet on the outside of the winding roller (502) is attached to one end of the cylindrical battery, and the second electric push rod (504) operates so that the pressing plate (505) compacts the insulating sheet; S7, the conveyor belt (104) conveys the cylindrical batteries with the insulating sheet attached to the inner side of the receiving mechanism (6), and the cylindrical batteries are further inspected by two inspection probes (603). The qualified cylindrical batteries are pushed into the receiving box by the push plate (608) after the second hydraulic cylinder (607) works.
