Figure 1

[0058] Step one, disc disassembling and sorting of the full-load tray 4 of the battery cell 5:

[0059] ​The full tray 4 moves from right to left at the right end of the upper layer of the main conveying line 16, the corresponding pneumatic stop mechanism is raised to stop the tray 4 at a position close to the first conveying branch line 17, and the corresponding lifting and moving mechanism is raised and then lowered to make the tray 4 move from top to bottom into the first conveying branch line 17. The corresponding pneumatic stop mechanism is raised to stop the tray 4 at an upper tray disassembling station 2, and the corresponding lifting and moving mechanism is raised and then lowered to make the tray 4 move from right to left into the tray disassembling station 2. The robot 9 grabs the battery cell 5 on the tray 4 in the tray disassembling station 2 to the first pull belt line 12 of the transfer platform 11 of the tray disassembling mechanism 7, and the identification device on the transfer platform 11 identifies the type of the battery cell 5 and docks the identified battery cell 5 on the first pull belt line 12 to the second pull belt line 13 of the corresponding storage conveying assembly 6. After the battery cell 5 on the first pull belt line 12 of the transfer platform 11 is classified and transferred, the robot 9 continues to grab the battery cell 5 and place it on the first pull belt line 12 of the transfer platform 11, and the transfer platform 11 continues to identify and classify the battery cell 5.

[0060] Meanwhile, a new full tray 4 moves from right to left at the right end of the upper layer of the main conveying line 16, the corresponding pneumatic stop mechanism is raised to stop the full tray 4, and the corresponding lifting and moving mechanism is raised and then lowered to make the full tray 4 move from top to bottom. The corresponding pneumatic stop mechanism is raised to stop the full tray 4 at a lower tray disassembling station 2, and the corresponding lifting and moving mechanism is raised and then lowered to make the full tray 4 move from right to left and move to the lower tray disassembling station 2. After the robot 9 finishes grabbing the battery cell 5 on the upper tray disassembling station 2, it continues to grab the battery cell 5 on the lower tray disassembling station 2 alternately.

[0061] Among them, the full tray 4 conveyed by the conveying line 1 alternately moves to the two tray disassembling stations 2, and the robot 9 alternately completes the transfer of the battery cell 5 on the workbench to the transfer platform 11, the transfer platform 11 identifies the type of the battery cell 5 and docks it to the second pull belt line 13 of the corresponding storage conveying assembly 6 to complete the transfer and sorting of the battery cell 5.

[0062] Step two, tray the sorted battery cell 5:

[0063] The sorted battery cell 5 moves from right to left on the corresponding storage conveying assembly 6. Taking the uppermost storage conveying assembly 6 as an example, there are four second pull lines 13 on the storage conveying assembly 6, corresponding to the identified battery cell 5 of a certain type on the transfer platform 11 of the receiving and disassembling mechanism 7. When the battery cell 5 on the storage conveying assembly 6 moves from right to left to the left end of the second pull line 13, the stopper is started to stop the battery cell 5, and the subsequent battery cell 5 is arranged in the channel from left to right in turn. When the length of the arranged battery cell 5 reaches the storage limit of the second pull line 13, the full line sensing device 14 sends a tray filling information. The transfer platform 11 of the tray filling mechanism 8 receives the tray filling information, moves to the outlet end of the second pull line 13, the stopper is closed, and the battery cell 5 corresponding to the second pull line 13 on the storage conveying assembly 6 is filled into the first pull line 12 of the transfer platform 11 of the full tray mechanism. When the first pull line 12 of the transfer platform 11 is full of battery cells 5, the cylinder stopper on the second pull line 13 is started to stop the battery cell 5 on the second pull line 13. The transfer platform 11 of the tray filling mechanism 8 moves to the range of the mechanical hand 9, and the mechanical hand 9 grabs the battery cell 5 of a certain type on the transfer platform 11 into the empty tray 4 at the upper full station. When all the battery cells 5 are grabbed into the empty tray 4, the transfer platform 11 of the tray filling mechanism 8 continues to receive the battery cell 5 from the second pull line 13 and continues to grab the battery cell 5 by the mechanical hand 9 and put it into the empty tray 4 until the empty tray 4 is filled.

[0064] The battery cell 5 on the other storage conveying assembly 6 is filled in the same way as the above-mentioned battery cell 5 filling step, which will not be repeated. Assuming that when a certain type of battery cell 5 has not been filled into the empty tray 4, the tray filling information from the other storage conveying assembly 6 is received, the transfer platform 11 needs to complete the ongoing work immediately and receive other types of battery cells 5 from the other storage conveying assembly 6, and then the other types of battery cells 5 are grabbed by the mechanical hand 9 and put into the empty tray 4 on the lower tray filling station 3. When the empty trays 4 on the two tray filling stations 3 are filled with classified battery cells 5, they move from right to left, the corresponding pneumatic stop mechanism is raised, and the corresponding lifting and moving mechanism is raised and then lowered to make the full tray 4 move from bottom to top along the second conveying branch line 18. When it moves close to the pneumatic stop mechanism of the conveying main line 16, if there is a full tray 4 running on the upper layer of the conveying line 1, the corresponding pneumatic stop mechanism is raised to stop the full tray 4 moving from bottom to top, to avoid the collision between the tray 4 on the conveying main line 16 and the tray 4 on the second conveying branch line 18. After the tray 4 on the conveying main line 16 moves past, the pneumatic stop mechanism at the upper end of the second conveying branch line 18 is lowered, the pneumatic stop mechanism close to the second conveying branch line 18 of the conveying main line 16 is raised, and the full tray 4 on the second conveying branch line 18 passes through the lifting and moving mechanism between them, which is raised and then lowered to make the full tray 4 on the second conveying branch line 18 move to the tray 4 on the conveying main line 16, which moves from right to left to the next process.

[0065] Step three, the transfer of empty tray 4 after sorting is completed:

[0066] After the full tray 4 on the two unpacking stations 2 is sorted to the corresponding storage conveying assembly 6, the empty tray 4 is moved to the lifting and transferring mechanism between the first conveying branch line 17 and the unpacking station 2, and the pneumatic stop mechanism of the first conveying branch line 17 close to the unpacking station 2 is raised, the two empty trays 4 are moved from top to bottom, and are successively moved to the first interlayer lifting machine 19, the first interlayer lifting machine 19 lowers the empty tray 4 to the lower layer of the first conveying branch line 17, the empty tray 4 is moved from bottom to top on the lower layer, and is moved to the pneumatic stop mechanism close to the conveying main line 16, if the lower layer of the conveying main line 16 has the empty tray 4 running, the pneumatic stop mechanism is raised to avoid the empty tray 4 on the lower layer of the conveying main line 16, if the position of the conveying main line 16 has no empty tray 4 running, the pneumatic stop mechanism of the conveying main line 16 close to the first conveying branch line 17 is raised, the lifting and transferring mechanism between the conveying main line 16 and the first conveying branch line 17 is raised and then lowered to make the empty tray 4 enter the conveying main line 16 and move from left to right, and return to the previous process, so that the empty tray 4 after the sorting of the battery cell 5 is recycled.

[0067] In addition, the empty tray 4 at the full tray station is provided in the following manner: when the empty tray 4 is needed at the tray packing station 3, the empty tray 4 is moved from left to right from the left end of the lower layer of the conveying main line 16, the pneumatic stop mechanism of the conveying main line 16 close to the second conveying branch line 18 is raised to stop the empty tray 4 coming from the left, the lifting and transferring mechanism between the conveying main line 16 and the second conveying branch line 18 is raised and then lowered to make the empty tray 4 move from top to bottom on the lower layer of the second conveying branch line 18, move to the second interlayer lifting machine 20, the second interlayer lifting machine 20 raises the empty tray 4 to the upper layer of the second conveying branch line 18, the empty tray 4 continues to move from bottom to top on the upper layer of the second conveying branch line 18, the pneumatic stop mechanism of the second conveying branch line 18 close to the tray packing station 3 is raised to stop the empty tray 4, and is raised and then lowered to move the empty tray 4 to the tray packing station 3 respectively, so as to provide the empty tray 4 for the sorted battery cell 5 to pack.

[0068] The above description is only the preferred embodiment of the present application, and does not limit the implementation and protection scope of the present application. For those skilled in the art, it should be realized that any equivalent replacement and obvious changes made according to the content of the present application can be included in the protection scope of the present application.
