In the first direction, the minimum distance between the first limit portions is smaller than the minimum distance between the second limit portions.

[0016] In the above scheme, a part of the battery cells between the second limiting parts can be transported in the direction opposite to the conveying direction, which can prevent the blockage of the outlet channel and prevent the battery cells transported in the reverse direction from being output from the inlet.

[0066] The conveying assembly 10 and the reflux assembly 20 described in the embodiments of the present application are not limited to the two structures described above, but for the sake of simplicity, the following embodiments are described by taking the conveying assembly 10 including a conveyor belt and a first roller, and the reflux assembly 20 including a reflux conveyor belt and a second roller as examples.

[0067] Optionally, in the second direction Y, the conveying component 10 and the reflux component 20 are located in the same plane for supporting one side of the battery cell 200, so as to ensure the effectiveness of moving a portion of the multiple battery cells 200 conveyed by the conveying component 10 along the reflux direction R by the reflux component 20, and to ensure the safety of the battery cell 200, and to prevent the battery cell 200 from tilting during transportation, thereby helping to improve the reliability of the material sorting device 100.

[0068] Optionally, the battery cell 200 may be a cylindrical battery cell 200 , a prismatic battery cell 200 , or a battery cell 200 of other shapes. However, for simplicity of description, the following embodiments are described by taking the cylindrical battery cell 200 as an example.

[0069] The limiting assembly 30 is used to guide the multiple battery cells 200 to be transported in the conveying cavity 30a to prevent them from escaping from the conveying cavity 30a, thereby ensuring the safety of the battery cells 200 and further improving the reliability of the material sorting device 100.

[0070] Optionally, the limiting assembly 30 is arranged on one side of the conveying assembly 10 and the reflux assembly 20 in the second direction Y to enclose the two to form a conveying cavity 30a. Optionally, the limiting assembly 30 may have an opening that passes through the conveying cavity 30a along the second direction Y, so that the multiple battery cells 200 in the conveying cavity 30a can be displayed during the conveying process, which is convenient for the operator to deal with it in time when abnormal operating conditions occur.

[0071] Optionally, in the second direction Y, there is a certain gap between the limiting assembly 30 and the conveying assembly 10 and the reflux assembly 20, and the gap is smaller than the axial length of the battery cell 200 conveyed by the material sorting device 100 to prevent the battery cell 200 from falling off through the gap.

[0072] Optionally, in the first direction X, there is a certain gap between the conveying assembly 10 and the reflux assembly 20 to avoid interference therebetween, and the gap is smaller than the diameter of the battery cell 200 conveyed by the material sorting device 100 to prevent the battery cell 200 from falling off through the gap.

[0073] The projection of the output channel 302 in the second direction Y is at least partially located in the conveying assembly 10 to ensure the effectiveness of the battery cells 200 being able to enter the conveying cavity 30a from the confluence port 301 and be output from the output channel 302. Optionally, the projection of the output channel 302 in the second direction Y may be entirely located in the conveying assembly 10. Of course, it may also be partially located in the conveying assembly 10, and the output channel 302 may also be connected to the accommodating cavity of other accommodating devices to accommodate the orderly arranged battery cells 200.

[0074] Optionally, the opening size of the output channel 302 in the first direction X is slightly larger than the diameter of the battery cell 200, so that the output channel 302 can only accommodate one battery cell 200 in the second direction Y, so that multiple battery cells 200 can be output in rows through the output channel 302, thereby sorting them from a disordered state to an ordered state, thereby ensuring the sorting effect of the material sorting device 100 on the battery cells 200.

[0075] Optionally, the output channel 302 is disposed on a side of the conveying component 10 close to the reflux component 20 along the first direction X, so as to better prevent the battery cells 200 near the output channel 302 from being blocked.

[0077] By configuring in this manner, the efficiency of outputting the battery cells 200 in rows through the material sorting device 100 can be improved, thereby facilitating the improvement of the material sorting efficiency of the material sorting device 100 .

[0078] The conveying component 10 is provided with a reflux component 20 on both sides in the first direction X, and is provided with two output channels 302 for the battery cells 200 to be output in rows, so that the battery cells 200 can generate vortices near the two output channels 302 to reduce the probability of blockage on the conveying component 10, thereby facilitating improving the efficiency of the battery cells 200 being output in rows through the material sorting device 100.

[0079] Optionally, the two output channels 302 are respectively arranged on one side of the conveying component 10 close to the reflux component 20 along the first direction X, which is beneficial to better prevent the battery cells 200 near the output channels 302 from being blocked, so that the battery cells 200 can be quickly output from the output channels 302, thereby improving the material sorting efficiency of the material sorting device 100.

[0080] In some embodiments, in the conveying direction F, the length dimension of the reflux component 20 is smaller than the length dimension of the conveying component 10 , and the reflux component 20 is disposed on a side of the conveying component 10 along the conveying direction F away from the confluence port 301 .

[0081] By configuring in this manner, the reflux assembly 20 can reversely transport the battery cells 200 near the outflow channel to prevent blockage.

[0082] Furthermore, setting the reflux assembly 20 shorter is beneficial to reducing the processing cost, thereby helping to reduce the cost of the material sorting device 100.

[0085] By arranging the output channel 302 on the second conveying member 12 protruding from the first conveying member 11 and the reflux assembly 20 along the conveying direction F, the efficiency of outputting the battery cells 200 in rows is improved, thereby improving the material sorting efficiency of the material sorting device 100 .

[0086] It is understandable that the second conveying member 12 is arranged to protrude from the first conveying member 11 so that the battery cells 200 located in the output channel 302 can continue to be transported a certain distance by the second conveying member 12 , which is beneficial to improving the efficiency of the battery cells 200 entering the output channel 302 .

[0087] Optionally, when the reflux component 20 is arranged on one side of the conveying component 10 along the first direction X, the number of the second conveying member 12 is one, and it is arranged between the reflux component 20 and the first conveying member 11; when the reflux components 20 are arranged in pairs and are respectively located on both sides of the conveying component 10 along the first direction X, the number of the second conveying members 12 is two, and they are respectively arranged between the reflux component 20 and the first conveying member 11.

[0088] By configuring the conveying assembly 10 transporting along the conveying direction F to include a first conveying member 11 and one or two second conveying members 12 , it is helpful to improve the conveying efficiency of the battery cells 200 , thereby helping to improve the material sorting efficiency of the material sorting device 100 .

The guiding member 32 and at least one limiting member 31 are spaced apart and form an output channel 302. An inlet 301 is formed between the limiting members 31 arranged in pairs.

[0094] By configuring the limiting assembly 30 to include a limiting member 31 and a guiding member 32 , the structure is simple and easy to assemble.

[0095] It is understandable that the multiple battery cells in the conveying chamber 30a can be limited by the limit member 31 for transportation in the conveying chamber 30a to prevent them from escaping from the conveying chamber 30a and causing safety problems. The guide member 32 is spaced apart from at least one limit member 31 to form an output channel 302. That is to say, the guide member 32 is arranged on the side away from the confluence port 301 along the conveying direction F, so that when the battery cell 200 in the conveying chamber 30a moves to the vicinity of the guide member 32, it can be abutted by the guide member 32 to move to the position of the output channel 302, which is beneficial to improve the efficiency of the battery cell 200 output from the output channel 302, thereby helping to improve the efficiency of the material sorting device 100 for the battery cell 200.

[0096] Optionally, the limiting member 31 and the guiding member 32 may be configured as a plate-like structure, so as to improve the space utilization of the accommodating cavity 30 a and transport more battery cells 200 .

[0097] Optionally, the limiting assembly 30 further includes a limiting frame for fixing and supporting the limiting member 31 and the guiding member 32 .

[0098] In some embodiments, in the conveying direction F, the limit member 31 includes a first limit portion 311, a second limit portion 312 and a third limit portion 313 connected in sequence, and an inlet 301 is formed between the first limit portions 311 arranged in pairs, and at least one third limit portion 313 is spaced apart from the guide member 32 to form an output channel 302. In the first direction X, the minimum distance between the first limit portions 311 is smaller than the minimum distance between the second limit portions 312.

[0099] By configuring in this way, a portion of the battery cells 200 between the second limiting portions 312 can be transported in a direction opposite to the conveying direction F, which can prevent the battery cells 200 being transported in the reverse direction from being output from the inlet 301 while preventing the blockage near the output channel 302 .

[0100] That is to say, in the first direction, the length dimension of the conveying chamber 30a between the first limit portions 311 is smaller than the length dimension between the second limit portions 312, so that the battery cells 200 located at the junction of the first limit portions 311 and the second limit portions 312 generate eddy currents, thereby preventing a part of the battery cells 200 from moving along the reflux direction R to the confluence 301, and being driven by the battery cells 200 transported along the conveying direction F to move along the conveying direction F.

[0101] Optionally, the projection of the second limiting portion 312 in the second direction Y is located in the reflux assembly 20, the projection of the first limiting portion 311 in the second direction Y is located in the second conveying member 12, or is located between the first conveying member 11 and the second conveying member 12, at least part of the projection of the third limiting portion 313 in the second direction Y is located in the second conveying member 12, or is located between the first conveying member 11 and the second conveying member 12, at least part of the projection of the guide member 32 in the second direction Y is located in the first conveying member 11, and at least part of the projection is located in the second conveying member 12, or is located between the first conveying member 11 and the second conveying member 12, so as to ensure the effectiveness of the limiting assembly 30, the conveying assembly 10 and the reflux assembly 20 to form a vortex with multiple battery cells 200, and to output disordered battery cells 200 in rows from the output channel 302.

[0102] Optionally, in the first direction X, the spacing between the first limiting portions 311 arranged in pairs is set at an equal distance, and the spacing between the second limiting portions 312 arranged in pairs is set at an equal distance, which is beneficial to increase the conveying space of the conveying cavity 30a.

[0103] In some embodiments, the second limiting portion 312 has a straight segment 3121 and arc segments 2122 respectively connected to both sides of the straight segment 3121 along the conveying direction F, wherein one arc segment 2122 is connected to the first limiting portion 311 , and the other arc segment 2122 is connected to the third limiting portion 313 .

[0104] By providing the arc segment 2122 to respectively connect the first limiting portion 311 and the third limiting portion 313, the battery cell 200 can be prevented from getting stuck at the connection between the first limiting portion 311 and the second limiting portion 312, and the second limiting portion 312 and the third limiting portion 313, and the arc segment 2122 is beneficial to ensuring the safety of the battery cell 200.

[0105] Optionally, the arc segment 2122 may be arranged to protrude toward the side close to the delivery cavity 30a, or may be arranged to protrude away from the delivery cavity 30a. Optionally, the arc segments 2122 on both sides of the straight segment 3121 may be arranged to have the same structure, or may be arranged to have different structures.

[0106] In some embodiments, the guide member 32 includes a protruding portion 321 and a guiding portion 322 connected in sequence, an output channel 302 is formed between the guiding portion 322 and the limiting member 31 , and the protruding portion 321 protrudes from the output channel 302 along the conveying direction F.

[0107] By configuring in this manner, the protrusion 321 can guide the battery cell 200 to move toward the output channel 302 , which is beneficial to improving the material sorting efficiency of the material sorting device 100 .

[0108] Optionally, at least a portion of the guide portion 322 may be extended along the conveying direction F to be spaced apart from at least one stopper 31 and form an output channel 302 .

[0109] Optionally, when the number of the output channels 302 is set to two, the guide portions 322 are provided in pairs and are respectively connected to the protruding portions 321 .

[0110] In some embodiments, the projection of the protrusion 321 in the first direction X is an arc-shaped structure.

[0111] By configuring the protrusion 321 to be an arc-shaped structure, the safety of the battery cell 200 is ensured, thereby facilitating the improvement of the reliability of the material sorting device 100 .

[0112] When the battery cell 200 is transported to abut against the protrusion 321 , the protrusion 321 is configured as an arc structure to ensure the safety of the battery cell 200 after abutment, prevent deformation or even damage, and improve the reliability of the material sorting device 100 .

[0113] In a second aspect, an embodiment of the present application further provides a stacking device, comprising the material sorting device 100 in any of the aforementioned embodiments.

[0114] Optionally, the stacking device also includes a silo and a containing device. The material sorting device 100 is arranged between the silo and the stacking device. The silo is used to provide a plurality of battery cells 200. The material sorting device 100 can sort the disordered battery cells 200 into ordered battery cells 200. The stacking device is used to stack the ordered battery cells 200 for transportation, inspection or assembly.

[0115] The stacking device provided in the embodiment of the present application includes the material sorting device 100 capable of improving the material sorting efficiency, and therefore, is helpful to improve the stacking efficiency of the stacking device.
