The cylindrical batteries can be further inspected by the two detection probes 603, and then the second hydraulic cylinder 607 works so that the push plate 608 can push the qualified cylindrical batteries into the receiving box, so that the cylindrical batteries can be collected conveniently.

[0043] like Figure 6 As shown, the sorting steps of a cylindrical battery voltage test sorting machine of the utility model are: S1, the material tray 103 moves along the chute 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.

[0044] S2, the servo motor 308 rotates the placement plate 305 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 is operated to move the mounting frame 303 along the movable groove 302.

The movable groove 302 can limit the movement of the mounting frame 303 so that it remains stable during the movement.

[0045] S3. The transfer mechanism 2 in the middle position works so that the first electric push rod 204 can push 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. The transfer mechanism 2 between the conveyor belt 104 and the flipping mechanism 3 works to transfer the cylindrical battery on the inner side of the placement plate 305 to the inner side of the adjacent conveyor belt 104. The cylindrical battery can be transported through the conveyor belt 104, and the movement of the movable seat 203 can be limited by the slide rail 202, so that the cylindrical battery remains stable during the transfer process.

[0046] S4. The cylindrical batteries are conveyed to the top of the voltage testing device 4 through the conveyor belt 104. The open circuit voltage and load voltage of the cylindrical batteries are tested by the voltage testing device 4 for sorting the cylindrical batteries. The open circuit voltage and load voltage of the cylindrical batteries can be tested by the voltage testing device 4. The cylindrical batteries that pass the test are continuously conveyed through the conveyor belt 104, and the cylindrical batteries that fail the test are pushed out from the top of the voltage testing device 4 for convenience of subsequent processing.

[0047] S5. The cylindrical batteries that have passed the inspection are transferred through the last transfer mechanism 2, so that they are transferred from one conveyor belt 104 to the inner side of another conveyor belt 104, and the qualified cylindrical batteries are transported by the conveyor belt 104.

The second electric push rod 504 operates so that the pressure plate 505 compacts the insulating sheet. The winding roller 502 rotates to discharge the insulating sheet so that the insulating sheet can fit with one end of the cylindrical battery. The second electric push rod 504 operates so that the pressure plate 505 compacts the insulating sheet to avoid the insulating sheet falling off. At the same time, the winding roller 503 can rewind the waste material of the insulating sheet strip to avoid the strip becoming messy.

[0049] S7, the conveyor belt 104 transports the cylindrical batteries with insulating sheets to the inner side of the receiving mechanism 6, and the cylindrical batteries can be further inspected by the two detection probes 603. The qualified cylindrical batteries are pushed into the receiving box by the second hydraulic cylinder 607. The cylindrical batteries with insulating sheets are further inspected by the two detection probes 603, and the second hydraulic cylinder 607 is operated so that the push plate 608 can push the cylindrical batteries that have passed the test into the inside of the receiving box. The cylindrical batteries that have passed the test can be received through the receiving box.

[0050] In summary, compared with the traditional cylindrical battery voltage test and sorting machine, the utility model can conveniently flip the vertical cylindrical batteries in the material tray 103 into a horizontal state through the flipping mechanism 3, and can conveniently transfer the cylindrical batteries between different processes through the three transfer mechanisms 2, so that the cylindrical batteries can maintain continuity during the transportation process, and then the open circuit voltage and load voltage of the cylindrical batteries can be tested through the voltage testing device 4, and the cylindrical batteries can be conveniently sorted. The insulating sheet can be pasted to the test plate through the insulating sheet feeding mechanism 5. At one end of the qualified cylindrical battery, the second electric push rod 504 works so that the pressure plate 505 can compact the pasted insulating sheet to prevent the insulating sheet from falling off. Then, the cylindrical battery can be further inspected by the detection probe 603 of the receiving mechanism 6. The second hydraulic cylinder 607 works so that the push plate 608 can push the qualified cylindrical battery into the receiving box for receiving operation, thereby ensuring the continuity of the cylindrical battery voltage test, improving the efficiency of the cylindrical battery voltage test and sorting work, and thus improving the production efficiency of the cylindrical battery.
