[0046] The working principle of the embodiment 1 is as follows: when in use, by supporting the bottom plate 12 to maintain a normal state, the receiving cavity 15 can be driven to align vertically with the bottom center of the storage cavity 23, and the assembled lithium batteries from the outside can be stacked one by one and placed inside the storage cavity 23, so that the lithium batteries can fall into the top of the closing plate 20. By the restriction of the receiving cavity 15, the top of the lithium battery can be flush with the top of the receiving cavity 15. Then, the first drive motor 29 can be started to drive the threaded rod 30 to rotate clockwise, and the sleeve plate 11 is threadedly sleeved on the threaded rod 30, so that the threaded rod 30 can drive the sleeve plate 11 to move to the front end, and the sleeve plate 11 moves in the sliding groove inside the side end of the support base 28 close to the first drive motor 29, so that the support bottom plate 12 It can move in a straight line inside the support base 28. Then, when the support bottom plate 12 is displaced, the strong magnetic sheet 16 is adsorbed and fitted with the iron plate 25, so that when the support bottom plate 12 is displaced, the partition cross plate 27 can be driven to move at the same time. The partition cross plate 27 is slidably inserted between the two limiting side sleeves 24, so that the partition cross plate 27 can move in a straight line. The front end of the partition cross plate 27 is aligned with the two groups of lithium batteries, so that when the support bottom plate 12 is displaced, the front end of the partition cross plate 27 can be driven to enter the bottom end of the lithium battery in the upper layer of the storage cavity 23, thereby preventing the lithium battery in the upper layer of the storage cavity 23 from falling downward when the support bottom plate 12 is displaced to the front end. Then, when the support bottom plate 12 continues to move, the partition cross plate 27 can be driven The support bottom plate 12 moves to the front end to the extreme position, so that the partition cross plate 27 can close the bottom end of the storage cavity 23. At the same time, the anti-drop sheet 26 contacts the limiting side sleeve 24 to prevent the partition cross plate 27 from falling off. Subsequently, when the support bottom plate 12 continues to move, the strong magnetic suction sheet 16 can be driven to disengage from the iron plate 25, so that the support bottom plate 12 can continue to move toward the front end. At this time, the support bottom plate 12 will drive the photoelectric sensor 13 to move to contact the extended contact frame 5 at the rear end of the lithium battery sealing device 4, so that the nozzle 14 can be started, and the air outlet of the nozzle 14 is flush with the top surface of the receiving cavity 15, so that the dust and impurities attached to the top of the lithium battery can be blown away. Subsequently, when the support bottom plate 12 drives the receiving cavity 15 to move When it reaches the bottom of the lithium battery sealing device 4, the lithium battery sealing device 4 can be started to seal the lithium battery inside the receiving cavity 15. Subsequently, the supporting bottom plate 12 will continue to drive the receiving cavity 15 to move toward the front end until the alignment rod 3 penetrates the front support plate 19 and contacts the rear end plate 17. Through the restriction of the alignment rod 3, the rear end plate 17 will drive the closing plate 20 to move toward the end away from the front support plate 19, so that the closing plate 20 can open a gap with the bottom end of the receiving cavity 15, so that the lithium battery inside the receiving cavity 15 can fall downward, and the key on the top of the rear end plate 17 slides in the groove at the bottom end of the supporting bottom plate 12, so that the rear end plate 17 can be ensured to move in a straight line. Subsequently, when the supporting bottom plate 12 moves to the limit position,The alignment rod 3 can squeeze the rear end plate 17 to move to the extreme position away from the front end support plate 19, so that the sealed lithium battery can fall downward to the end of the support base 28 away from the first drive motor 29. The bottom of the end of the support base 28 away from the first drive motor 29 is inclined at 45 degrees, so that the lithium battery can slide along the slope inside the support base 28 to the receiving plate 33. At the same time, when the support bottom plate 12 moves toward the front end, it can also drive the first rack 10 to pass through the side end of the gear 31 away from the second rack 32, thereby driving the second rack 32 to move toward the end close to the first drive motor 29, so that the displacement bracket 36 can approach the end close to the first drive motor 29. When the lithium battery slides along the internal slope of the support base 28 onto the receiving plate 33, the vertical plate 37 can be driven to rotate toward the end away from the support base 28 until the lithium battery completely passes through the vertical plate 37. Subsequently, the first drive motor 29 can be started to drive the threaded rod 30 to rotate counterclockwise, so that the support base 12 is reset to the rear end. At this time, the support base 12 can drive the first rack 10 to pass through the gear 31, thereby driving the second rack 32 to move toward the end away from the first drive motor 29, so that the second rack 32 can drive the displacement bracket 36 to move toward the end away from the first drive motor 29. At this time, the vertical plate 37 can be prevented from approaching the support base 2 by the restriction of the limiting cross frame 34. 8 is rotated, so that when the displacement bracket 36 moves toward the end away from the first drive motor 29, the vertical plate 37 can push the lithium battery to move on the receiving plate 33 toward the end away from the support base 28, until the first rack 10 completely passes the gear 31, the vertical plate 37 can push the lithium battery to be completely removed from the receiving plate 33, completing the discharge of the lithium battery. Subsequently, when the support bottom plate 12 drives the rear end plate 17 to completely disengage from the alignment rod 3, the elasticity of the first spring 18 will drive the closing plate 20 to reset, so that the closing plate 20 can perform the receiving work at the bottom end of the receiving cavity 15 again. Subsequently, when the support bottom plate 12 moves to the bottom end of the storage cavity 23, it can drive the strong The magnetic sheet 16 is again adsorbed and fitted with the iron plate 25, so that when the support base plate 12 is reset, the iron plate 25 can be driven to squeeze the partition horizontal plate 27 and move toward the rear end at the same time, until the support base plate 12 is completely reset, the receiving cavity 15 can be vertically aligned with the bottom center of the storage cavity 23 again, so that the front end of the partition horizontal plate 27 can be vertically aligned with the inner rear end surface of the storage cavity 23, so that the lithium battery on the upper layer of the storage cavity 23 can fall into the interior of the receiving cavity 15, and the closing plate 20 carries the lithium battery again. When the device is in use, the key on the side end of the second rack 32 slides in the slot inside the side end of the support base 28, so that the second rack 32 can be supported to move in a straight line to complete the work.

[0047] Example 2

[0048] On the basis of Example 1, Fig.10As shown, the receiving plate 33 also includes a temporary receiving plate 38 and a second driving motor 39 . The temporary receiving plate 38 is fixedly mounted at the bottom front end of the receiving plate 33 , and the second driving motor 39 is fixedly mounted at the top center of the temporary receiving plate 38 .

[0049] When implementing this embodiment, each time the temporary receiving plate 38 rotates, the second drive motor 39 can be driven to rotate 180°, so that the second drive motor 39 is always located at the bottom center of the receiving plate 33, so that the second drive motor 39 can receive the lithium battery dropped from the receiving plate 33. At the same time, when the temporary receiving plate 38 is started, the second drive motor 39 can be driven to rotate, so that the end of the second drive motor 39 that does not carry the lithium battery can be rotated to the bottom of the receiving plate 33, so that the second drive motor 39 can rotate to receive the sealed lithium battery and complete the work of transferring the lithium battery again.
