DETAILED DESCRIPTION

[0034] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0035] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] like Figures 1 to 5 As shown, the present application discloses a battery cell loading and unloading equipment, which includes a material box, a loading platform group 300, a telescopic drive member 400 and a conveying assembly 500, wherein the material box includes a material box body 100 and a sliding support member 200, wherein the telescopic drive member 400 can be a telescopic cylinder, a telescopic electric cylinder, a motor and a screw transmission matching assembly, etc., and the present application does not impose any limitation on this.

[0038] Specifically, along the load-bearing direction of the material box body 100, one end of the sliding support 200 extends into the material box body 100 and slides together, and the other end of the sliding support 200 is exposed outside the material box body 100. The conveying assembly 500 is arranged on the driving end of the telescopic driving member 400, and the conveying assembly 500, the material box body 100 and the loading platform group 300 are arranged in sequence.

[0039] Of course, the material box body 100 may be provided with a first opening, or the material box body 100 may be provided with a first opening and a second opening that are opposite and connected, and the present application does not impose any limitation on this.

[0040] When the loading platform group 300 carries the battery cell group and the magazine body 100 is in an unloaded state, the telescopic driving member 400 drives the conveying assembly 500 to at least partially pass through the hollow part of the magazine body 100 to move to the loading platform group 300 to carry the battery cell group and convey the battery cell group to the magazine body 100; when the battery cell group is located in the magazine body 100 and is only carried by one end of the sliding support member 200, a transmission channel is provided between the bearing surface of the sliding support member 200 and the magazine body 100, wherein only an avoidance space is formed between one end of the sliding support member 200 and the bearing surface of the magazine body 100, so that the telescopic driving member 400 drives the conveying assembly 500 to move into the transmission channel and convey the battery cell group to the loading platform group 300. The battery cell group is a plurality of stacked battery cell slices (i.e., formed by slicing and cutting a whole battery cell).

[0041] In the above structure, compared with transporting the battery cells one by one, through the cooperation of the telescopic driving member 400 and the transporting assembly 500, the telescopic driving member 400 drives the transporting assembly 500 to pass through the hollow part of the material box body 100 to the loading platform group 300 to carry the battery cell group, and transport the battery cell group to the material box, thereby improving the loading efficiency. The carrying surface of the material box body 100 is coplanar with the supporting surface of one end of the sliding support member 200 to carry the battery cell group, or only the supporting surface of one end of the sliding support member 200 carries the battery cell group. The present application does not impose any restrictions on this. Similarly, the telescopic driving member 400 drives the transporting assembly 500 to move into the transmission channel and transport the battery cell group to the loading platform group 300. The supporting surface of the transporting assembly 500 is coplanar with the supporting surface of one end of the sliding support member 200 and carries the battery cell group. The transporting assembly 500 can separate the battery cell group from the material box body 100 as a whole, thereby improving the unloading efficiency.

[0042] Of course, since the transport assembly 500, the material box body 100 and the loading platform group 300 are arranged in sequence, the moving path of the transport assembly 500 driven by the telescopic driving member 400 is the shortest, thereby further improving the working efficiency.

[0043] In addition, there may be multiple loading platform groups 300, and there may also be multiple material boxes, telescopic drive members 400 and conveying components 500, and they are adapted one-to-one to the multiple loading platform groups 300, or there may be multiple material boxes, and they are arranged one-to-one relative to the multiple loading platform groups 300. The battery cell loading and unloading equipment may also include a translation drive member 700, and the telescopic drive member 400 is arranged at the driving end of the translation drive member 700. The translation drive member 700 can drive the telescopic drive member 400 to move to adapt one-to-one to the multiple loading platform groups 300, and the present application does not impose any restrictions on this. Among them, the translation drive member 700 may be a servo motor, a driving electric cylinder, etc. Of course, in order to avoid interference with other components and ensure the maximum stroke, the translation drive member 700 may be two stacked driving electric cylinders, driving air cylinders, etc., one of which drives the other to move, and the other drives the conveying component 500 to move, and the present application does not impose any restrictions on this.

[0044] In an optional solution, the loading platform group 300 may include a first lifting drive member 310 and a loading platform 320. Specifically, the loading platform 320 is arranged on the driving end of the first lifting drive member 310. When the telescopic drive member 400 drives the conveying assembly 500 to at least partially pass through the hollow part of the material box body 100 and move to the loading platform group 300 to carry the battery cell group, the first lifting drive member 310 drives the loading platform 320 to move away from the battery cell group.

[0045] The above structure cooperates with the first lifting drive member 310 and the loading platform 320. The loading platform 320 carries the battery cell group. The first lifting drive member 310 drives the loading platform 320 to move away from the battery cell group, thereby avoiding the telescopic drive member 400 directly driving the transport assembly 500 to transport the battery cell group, which causes the battery cell group to be scratched when it is separated from the loading platform 320, thereby avoiding the problem of uneven and disordered stacking of the battery cell group. Of course, the first lifting drive member 310 can be a cylinder, an electric cylinder, a motor, etc., and this application does not impose any restrictions on this.

[0046] In another optional scheme, the conveying assembly 500 may include a second lifting drive member 510 and a conveying member 520. Specifically, the second lifting drive member 510 is arranged on the driving end of the telescopic drive member 400, and the conveying member 520 is arranged on the driving end of the second lifting drive member 510. When the telescopic drive member 400 drives the conveying assembly 500 to at least partially pass through the hollow part of the material box body 100 and move to the loading platform group 300 to carry the battery cell group, the second lifting drive member 510 drives the conveying member 520 to move and lift the battery cell group away from the loading platform group 300.

[0047] The above structure uses the second lifting drive member 510 and the transport member 520, and the loading platform group 300 carries the battery cell group. The second lifting drive member 510 drives the transport member 520 to move and lift the battery cell group away from the loading platform group 300, thereby avoiding the telescopic drive member 400 directly driving the transport assembly 500 to transport the battery cell group, which causes the battery cell group to be scratched when it is separated from the loading platform group 300, thereby avoiding the problem of uneven and disordered stacking of the battery cell group. Of course, the second lifting drive member 510 can be a cylinder, an electric cylinder, a motor, etc., and this application does not impose any restrictions on this.

[0048] The conveying assembly 500 may include a telescopic cylinder and a clamping hand arranged at its driving end, and the conveying effect is achieved by clamping two opposite sides of the battery cell group. In an optional scheme, the conveying member 520 is a conveying fork, and the loading platform group 300 is provided with a groove A. When the telescopic driving member 400 drives the conveying assembly 500 to at least partially pass through the hollow part of the material box body 100 and move to the loading platform group 300 to carry the battery cell group, the conveying fork extends into the groove A and is coplanar with the carrying surface of the loading platform group 300 to carry the battery cell group.

[0049] In the above structure, the transport fork and the groove A are mutually sleeved to form a coplanar support surface, so that the transport fork can carry the battery cell group and the battery cell group can be lifted by the second lifting drive member 510, thereby avoiding interference between the transport fork and the loading platform group 300.

[0050] In an embodiment of the present application, the disclosed battery cell loading and unloading equipment may further include a bracket 600. Specifically, the bracket 600 is disposed on the telescopic driving member 400. The bracket 600 is provided with a limiting groove B. The bracket 600 can carry the material box body 100. The other end of the sliding support member 200 can be embedded in the limiting groove B. One end of the sliding support member 200 forms a supporting protrusion in the material box body 100.

[0051] In the above structure, the bracket 600 carries the material box body 100, and the other end of the sliding support member 200 can be embedded in the limiting groove B, so as to avoid the material box body 100 from being skewed or displaced relative to the bracket 600, thereby ensuring that the material box body 100 can be precisely positioned, facilitating the handling assembly 500 to load and unload the battery cell group.

[0052] In a further technical solution, one of the bracket 600 and the material box body 100 can be provided with a positioning pin 610, and the other can be provided with a positioning hole. Specifically, the positioning pin 610 and the positioning hole can be positioned and matched, so as to further improve the position accuracy between the material box body 100 and the bracket 600, and further facilitate the handling assembly 500 to load and unload the battery cell group.

[0053] In an embodiment of the present application, the sliding support member 200 may include a support seat 210 and a guide rod seat 220. Specifically, a through hole is opened at the bearing end of the material box body 100, and the support seat 210 and the guide rod seat 220 are connected. The guide rod seat 220 slides with the through hole, and one end of the guide rod seat 220 extends into the material box body 100, and the support seat 210 is exposed outside the material box body 100.

[0054] In the above structure, the guide rod seat 220 slides relative to the through hole, and one end of the guide rod seat 220 can reciprocate relative to the bearing end of the material box body 100, that is, away from or close to the bearing end of the material box body 100. When one end of the guide rod seat 220 moves close to the bearing end of the material box body 100, the cross-section of one end of the guide rod seat 220 is coplanar with the end face of the bearing end of the material box body 100; when one end of the guide rod seat 220 moves away from the bearing end of the material box body 100, one end of the guide rod seat 220 forms a supporting protrusion.

[0055] In a further technical solution, the guide rod seat 220 may include a guide rod 221 and a support plate 222. Specifically, the guide rod 221 is slidably matched with the through hole, and the two ends of the guide rod 221 are respectively connected to the support seat 210 and the support plate 222, and the support plate 222 may be away from or embedded in the groove A provided in the loading platform group 300. In the case where the support plate 222 is embedded in the groove A provided in the loading platform group 300, the support surface of the support plate 222 is coplanar with the support surface of the loading platform group 300; in the case where the support plate 222 is away from the groove A provided in the loading platform group 300, the support plate 222 is lifted to form a support protrusion.

[0058] In this step, the loading platform group 300 carries the battery cell group that has not been passivated, wherein the battery cell group is stacked as a whole and then placed on the loading platform group 300, or the battery cell slices after being sliced ​​by a dicing machine are moved one by one to the loading platform group 300 by a stacking hand, and this application does not impose any restrictions on this.

[0059] When the battery cell group that has completed the passivation and annealing treatment is located in the material box body 100 and is only supported by one end of the sliding support 200, the telescopic drive member 400 drives the conveying assembly 500 to move into the transmission channel. The supporting surface of the conveying assembly 500 is coplanar with the supporting surface of the sliding support 200 and supports the battery cell group. The telescopic drive member 400 drives the conveying assembly 500 to convey the battery cell group to the loading platform assembly 300.

[0060] In this step, the battery cell group that has completed the passivation and annealing treatment needs to be separated from the material box body 100 and stored or transported to the battery cell string welding equipment for preparation of battery string production. The material box can be recycled to carry the next sequence of unpassivated battery cell groups.
