[0039] As attached Figure 1-9 As shown, the present invention provides a chemical separation and capacity distribution logistics line, including a feeding device 1, a capacity separation device 2, a sorting device 3, a packaging device 4, a battery transport box 5 and a charging and discharging mechanism 6;

[0040] The battery transport box 5 includes a box body 51, a limiting cover 52 and a box cover 53. The box body 51 is provided with a plurality of electromagnetic accommodation slots 511 in an array for placing batteries 7. The limiting cover 52 is detachably connected to one side of the box body 51. The specific detachable connection method can be a snap connection, a magnetic connection, or a hinge. A limiting protrusion 521 is provided on the limiting cover 52 toward the electromagnetic accommodation slot 511. The limiting protrusion 521 and the electromagnetic accommodation slot 511 can be plugged and matched. On the one hand, it is convenient for the limiting cover 52 to align and limit the box body 51. On the other hand, after the limiting protrusion 521 is inserted into the electromagnetic accommodation slot 511, the battery in the electromagnetic accommodation slot 511 can be moved upward by a certain distance, so as to avoid the positive protrusion 71 of the subsequent battery 7 protruding from the end face of the limiting cover 52, resulting in the box body 51 and the limiting cover 52 being matched. During the transportation and movement, the positive protrusion 71 of the battery 7 may be rubbed. A locking groove 522 is provided on the side of the limiting cover 52 away from the box body 51 at the position of the limiting protrusion 521. The locking groove 522 is used for the subsequent insertion of the raised positive electrode current transfer sheet 611. The locking groove 522 is provided with a connecting groove 523 that passes through the limiting protrusion 521. The size of the connecting groove 523 is larger than the positive protrusion 71 of the battery 7. When the battery 7 is installed in the electromagnetic accommodation groove 511, the setting of the connecting groove 523 can, on the one hand, utilize the positive protrusion 71 of the battery 7 to insert into the connecting groove 523 to complete the positioning and locking of the battery 7, thereby improving the stability of the battery 7 in the electromagnetic accommodation groove 511. On the other hand, the positive protrusion 71 of the battery 7 can pass through the connecting groove 523 to be in contact and connected with the raised positive electrode current transfer sheet 611 in the charging and discharging mechanism 6.

[0041] The charging and discharging mechanism 6 includes a positive charging plate 61 detachably connected to the limiting cover 52 and a negative charging plate 62 detachably connected to the side of the box body 51 away from the limiting cover 52, wherein the specific detachable connection method can be a snap connection or a magnetic connection, and the positive charging plate 61 is provided with a raised positive charge transfer sheet 611 protruding toward the engaging groove 522, and the raised positive charge transfer sheet 611 is in contact with the positive protrusion 71, and the raised positive charge transfer sheet 611 is a raised structure. On the one hand, the raised positive charge transfer sheet 611 can be inserted into the engaging groove 522 to complete the positive charging plate 61 and the limiting cover. The positioning and alignment of the position cover 52, on the other hand, the protrusion contacts and cooperates with the positive protrusion 71 passing through the connecting groove 523 to complete the conductive connection, and the negative charging plate 62 is provided with a negative charging mechanism 621 that can move toward the electromagnetic accommodating groove 511, and the negative charging mechanism 621 is movably arranged on the negative charging plate 62, and the negative charging mechanism 621 can be moved to contact the negative pole 72 of the battery 7, and the battery 7 can be driven to move downward, thereby improving the contact success rate of multiple negative charging mechanisms 621 with the negative pole 72, and at the same time improving the contact success rate of the positive protrusion 71 with the protruding positive electrode charging sheet 611;

[0042] The feeding device 1 is used to feed the battery 7 into the multiple electromagnetic accommodation slots 511 in the assembled box body 51 and the limit cover 52, and assemble it with the charging and discharging mechanism 6 after the battery 7 is filled. Specifically, the feeding device 1 may include a material box conveyor line, a feeding mechanism and a transfer manipulator. The material box conveyor line is used to convey the box body 51 and the limit cover 52 that are assembled with each other. The feeding mechanism conveys the battery 7 to the multiple electromagnetic accommodation slots 511 on the box body 51. After the feeding is completed, the positive charging plate 61 is combined with the limit cover 52, and the negative charging plate 62 is assembled with the other end of the box body 51. Finally, after the assembly is completed, it is transferred to the capacity separation device 2 by the transfer manipulator;

[0043] The capacity division device 2 is used to store the assembled box body 51, the limit cover 52 and the charge-discharge mechanism 6, and to charge and discharge the battery 7 through the charge-discharge mechanism 6, and to obtain and record the capacity data of each battery 7. The capacity division device 2 is a capacity division cabinet structure. Since the charge and discharge of the battery 7 takes a long time, and it needs to be idle for a certain time after charging and discharging, multiple capacity division cabinets can be set for storage and charging and discharging. After the assembled box body 51, the limit cover 52 and the charge-discharge mechanism 6 are sent into the cabinet of the capacity division cabinet, the cabinet compartment A charging and discharging contact is provided, and the charging and discharging contact is respectively connected to the positive charging plate 61 and the negative charging plate 62, so as to realize charging and discharging of multiple batteries 7 at the same time, and finally record the capacity data of the battery 7 to provide data support for subsequent capacity division; wherein, the box body 51, the limit cover 52 and the charging and discharging mechanism 6 are assembled and then sent into the capacity division device 2, and the charging and discharging mechanism 6 and the limit cover 52 can be combined to block the two ends of the electromagnetic accommodation slot 511 of the box body 51, so as to prevent the battery 7 from falling out from the two ends of the electromagnetic accommodation slot 511 during the transfer process.

[0044] The sorting device 3 includes a sorting platform, a sorting manipulator and a spare battery compartment. The sorting manipulator transports the box body 51, the limit cover 52 and the charge and discharge mechanism 6 after charging and discharging and places them vertically on the sorting platform, then removes the charge and discharge mechanism 6 and the limit cover 52 from the box body 51, and transports them to the loading device 1 for the next batch of batteries 7 to be used for capacity sorting. After disassembly, since the box body 51 is in a vertical state, the battery 7 is horizontally placed in the electromagnetic accommodation slot 511 and will not flow out from both ends. Then, the sorting manipulator obtains the capacity data of each battery 7, pushes the battery 7 whose capacity does not meet the batch requirements from one side of the electromagnetic accommodation slot 511 and sends it into the spare battery compartment, and selects the spare batteries that meet the batch requirements in the spare battery compartment and inserts them into the vacant electromagnetic accommodation slot 511, so as to ensure that there is a batch of batteries 7 that meet the requirements in the box body 51 at the end, and the batteries 7 that do not meet the requirements can be sent to the spare battery compartment for combination use next time;

[0045] The packaging device 4 is used to assemble the box body 51 filled with qualified batteries 7 with the box cover 53 after sorting is completed, and transport it to the next workstation, so as to complete the volume-based logistics transportation of the batteries 7. Among them, the box body 51 and the box cover 53 can adopt an affordable plastic structure. Since the packaging and limiting requirements are met at this time, they can be shipped directly.

[0046] The chemical fractionation logistics line provided by the present invention can realize the fractionation and packaging transportation of the battery 7, and through the structural design of the battery transportation box 5 and the charging and discharging mechanism 6, it has the characteristics of convenient operation, guaranteed efficiency and stability during the loading, fractionation and sorting processes. The box body 51 continues the entire process of loading, fractionation, sorting and packaging of the battery 7, which can greatly reduce the assembly and disassembly procedures of the battery 7 and various equipment, and further improve the logistics efficiency.

[0047] In one embodiment, the limiting protrusion 521 is a boss structure, that is, the bottom size of the limiting protrusion 521 is larger than the top size, so as to provide guidance and positioning when the limiting protrusion 521 is inserted into the electromagnetic accommodation groove 511, thereby simplifying the assembly difficulty of the limiting cover 52 and the box body 51, and the root of the limiting protrusion 521 is gap-matched with the end of the electromagnetic accommodation groove 511 to ensure the matching effect and stability.

[0048] In one embodiment, the plurality of raised positive electrode transfer plates 611 are boss structures, i.e., the bottom dimension of the raised positive electrode transfer plate 611 is larger than the top dimension, thereby providing guidance and positioning when the raised positive electrode transfer plate 611 is inserted into the engaging groove 522, thereby simplifying the assembly difficulty of the positive charging plate 61 and the limiting cover 52, and the root of the raised positive electrode transfer plate 611 is gap-matched with the end of the engaging groove 522 to ensure the matching effect and stability.

[0049] In one embodiment, a first total electrical contact 612 is provided on the side of the positive charging plate 61, and a plurality of the protruding positive electrode current transfer plates 611 are connected in series in sequence and connected to the first total electrical contact 612, so as to facilitate the electrical connection between the positive protrusions 71 of all batteries 7 and the capacity division device 2.

One end of the spring 6213 abuts against the spring clamping plate 6212, and the other end abuts against the bottom of the sliding cavity 623. In this embodiment, The conductive rod 6211 is moved toward the side away from the box body 51 by the spring 6213. When the conductive rod 6211 needs to contact the negative electrode 72 of the battery 7, it is only necessary to press the conductive rod 6211 downward through the lower pressure plate set on the top of the cabinet compartment to simultaneously complete the docking of all the conductive rods 6211 with the negative electrode 72 of the battery 7, which can greatly improve the installation efficiency. At the same time, the lower pressure plate can be pressed on the upper end of the conductive rod 6211 by gravity, so that the force of the spring 6213 protects the conductive rod 6211 from excessively squeezing the negative electrode 72 of the battery 7, thereby avoiding excessive squeezing pressure on the battery 7.
