[0045] See also Figure 1 As shown, a battery cell conveying device corresponding to a preferred embodiment of the utility model includes: a first conveyor line 100, connected to a dicing device; a second conveyor line 200, connected to a string welding device, a cache station is formed between the second conveyor line 200 and the first conveyor line 100; a handling robot 300, used to carry the battery cells 400; wherein, a material box 500 and / or a loading platform 600 are placed at the cache station, the material box 500 is suitable for storing the battery cells 400 flowing out of the first conveyor line 100, and the loading platform 600 is suitable for storing the battery cells 400 delivered to the second conveyor line 200, and the moving range of the handling robot 300 covers the first conveyor line 100, the second conveyor line 200 and the cache station.

[0046] The utility model is provided with a first conveyor line 100 connected to the dicing device and a second conveyor line 200 connected to the string welding device. A handling robot 300 is connected between the first conveyor line 100 and the second conveyor line 200 to transfer the battery cells 400 from the first conveyor line 100 to the second conveyor line 200. Since the first conveyor line 100 and the second conveyor line 200 can operate independently, when one of the dicing device and the string welding device fails or is being debugged, the other device in normal working condition can continue to work normally. A buffer station is formed between the first conveyor line 100 and the second conveyor line 200, and a material box 500 and / or an upper The material table 600, when only the dicing equipment is working normally, during the cooperation between the first conveyor line 100 and the dicing equipment, qualified or unqualified battery cells 400 after dicing by the dicing equipment can be transported by the handling robot 300 from the first conveyor line 100 to the material box 500 for temporary storage, avoiding the operator to frequently unload the battery cells 400; when only the stringing equipment is working normally, several battery cells 400 that have passed the dicing can be placed on the loading table 600 first, and the handling robot 300 can load the battery cells 400 from the loading table 600 to the second conveyor line 200, thereby ensuring that the stringing equipment can work normally and avoiding the operator to frequently load the battery cells 400.

[0047] Further, the first conveyor line 100 and the second conveyor line 200 are parallel to the center line of the length direction and are on the same straight line, the output end of the first conveyor line 100 and the input end of the second conveyor line 200 are arranged oppositely, a buffer station is formed between the output end of the first conveyor line 100 and the input end of the second conveyor line 200, and the handling robot 300 is suitable for moving along the length direction of the first conveyor line 100 and / or the second conveyor line 200 to the output end of the first conveyor line 100, the input end of the second conveyor line 200 and the buffer station. The above structure can effectively simplify the structure of the handling robot 300. A visual inspection structure is provided on the conveying path of the first conveyor line 100 to inspect the battery cell 400 after dicing by the dicing equipment to determine whether the battery cell 400 is qualified.

[0048] Further, refer to Figure 2As shown, the handling robot 300 includes a transverse moving module 310, a lifting module 320 and a nozzle assembly 330. The transverse moving module 310 is suitable for moving along the length direction of the first conveyor line 100 and / or the second conveyor line 200. The lifting module 320 is transmission-connected to the transverse moving module 310 and is suitable for lifting and lowering in the vertical direction. The nozzle assembly 330 is transmission-connected to the lifting module 320 and is suitable for adsorbing or releasing the battery cell 400. When the transport robot 300 is working, the suction nozzle assembly 330 can be moved to the output end of the first conveyor line 100 under the cooperation of the transverse module 310 and the lifting module 320 to absorb the battery cells 400, and move to the material box 500 or the input end of the second conveyor line 200 as needed to unload the battery cells 400; in addition, the suction nozzle assembly 330 can also be moved to the loading platform 600 under the cooperation of the transverse module 310 and the lifting module 320 to absorb the battery cells 400 on the loading platform 600, and load the battery cells 400 to the input end of the second conveyor line 200.

[0049] Preferably, in this embodiment, there are two groups of nozzle assemblies 330, and they are arranged side by side along the length direction of the first conveyor line 100 and / or the second conveyor line 200. The two groups of nozzle assemblies 330 correspond one-to-one to two adjacent battery cells 400 on the first conveyor line 100, so that the handling robot 300 can absorb two battery cells 400 at the same time and transfer them to the second conveyor line 200, thereby improving the handling efficiency.

[0050] Furthermore, the first conveyor line 100 and the second conveyor line 200 cooperate to form a conveyor line group, and two conveyor line groups are arranged side by side along the width direction of the first conveyor line 100 and / or the second conveyor line 200 to improve the conveying efficiency of the conveying device. The transverse movement module 310 has two output ends, and the two output ends are provided with a lifting module 320, and each lifting module 320 is provided with two groups of nozzle assemblies 330, and the two groups of nozzle assemblies 330 correspond to the conveyor line group one by one.

[0051] Furthermore, when a material box 500 is placed at the buffer station, the material box 500 is adjacent to the output end of the first conveyor line 100, and the first conveyor line 100 is suitable for directly inputting unqualified battery cells 400 into the material box 500, while the handling robot 300 is suitable for transporting qualified battery cells 400 into the material box 500. By adopting the above structure, the operation process of the handling robot 300 can be simplified, the use frequency of the handling robot 300 can be reduced, and since unqualified battery cells 400 are usually treated as waste, they are directly input into the material box 500 through the first conveyor line 100, and there is no need to consider the damage of the battery cells 400.

[0052] Specifically, refer to Figure 3 and Figure 4As shown, the material box 500 includes a box body 510 and a guide plate 520. The box body 510 is located below the bearing surface of the first conveyor line 100 and is formed with a first receiving cavity 511 with an open top. One side of the guide plate 520 is connected to the top side of the box body 510, and the other side extends to the output end of the first conveyor line 100. When the first conveyor line 100 drives the battery cell 400 located on its bearing surface to be output from the output end, the battery cell 400 can flow onto the guide plate 520 and be input into the first receiving cavity 511 from the first conveyor line 100 under the guidance of the guide plate 520. Preferably, in the extension direction of the guide plate 520, the guide plate 520 is arranged to tilt upward, so that the battery cell 400 can flow into the first receiving cavity 511 more easily.

[0053] Furthermore, the battery cell 400 is a square sheet structure, and the first receiving cavity 511 is preferably a square cavity to match the battery cell 400. The qualified battery cells 400 are stacked and placed in the first receiving cavity 511 under the handling of the handling robot 300. Since the handling robot 300 can carry two battery cells 400 at a time, preferably, in one embodiment, the first receiving cavity 511 can be divided into two identical cavities by a partition, and the inner contour of the cavity is matched with the outer contour of the battery cell 400, and the handling robot 300 can put the two battery cells 400 into different cavities respectively.

[0054] However, since the size of the first receiving cavity 511 is usually larger than the size of the battery cell 400, in order to improve the reliability of unloading the battery cell 400, the handling robot 300 has position deviations during the handling process, and several stacked battery cells 400 are difficult to align completely. Moreover, since the battery cells 400 are relatively thin, the battery cells 400 are easily squeezed and damaged during the stacking process.

[0055] Preferably, in this embodiment, the material box 500 also includes a lining structure 530 detachably received in the first receiving cavity 511, and the lining structure 530 includes a vertical plate 531 and a first support plate 532, the vertical plate 531 is vertically placed at the bottom of the first receiving cavity 511, the number of the vertical plates 531 is at least two, and they are arranged in parallel, and the number of the first support plate 532 is at least one, which is connected between two adjacent vertical plates 531 and inclined to the vertical plates 531. The vertical plate 531 and the first support plate 532 are suitable for cooperating to separate the first receiving cavity 511 into at least one second receiving cavity 512. When the material box 500 needs to receive qualified battery cells 400, the lining structure 530 can be installed in the first receiving cavity 511, so that the handling robot 300 is suitable for carrying the qualified battery cells 400 from the first conveyor line 100 to the second receiving cavity 512. With the above structure, the battery cell 400 is easy to cut, and the first support plate 532 and the vertical plate 531 are suitable for supporting the battery cell 400. The battery cell 400 is suitable for precise positioning, which effectively avoids damage to the battery cell 400 during stacking.

[0056] Preferably, a flexible pad 533 is provided on one side of the second receiving cavity 512 formed by the vertical plate 531 and the first support plate 532, and the flexible pad 533 can buffer and protect the battery cell 400 to prevent the battery cell 400 from being damaged during the unloading process. The flexible pad 533 can be made of foam, flexible rubber pad, etc., and the utility model is not limited here.

[0057] In addition, since the handling manipulator 300 can simultaneously carry two battery cells 400 at a time, preferably, in this embodiment, there are three vertical plates 531, and they are arranged at equal intervals along the length direction of the first conveyor line 100 and / or the second conveyor line 200, and the two vertical plates 531 located on both sides are respectively in contact with the two opposite sides of the first receiving cavity 511, and there are two first support plates 532, one side of the first support plate 532 is connected to the top side of one of the vertical plates 531, and the other side of the first support plate 532 is connected to the bottom side of the other vertical plate 531. The two first support plates 532 are parallel, and in the vertical upward direction, the first support plate 532 is inclined toward the first conveyor line 100. Preferably, the vertical plate 531 and the first support plate 532 can be bent and formed as a whole to facilitate production.

[0058] Further, refer to Figure 5 and Figure 6 As shown, the loading platform 600 includes a platform body 610, a carrier 620 and a lifting assembly 630. The carrier 620 is detachably placed on the platform body 610, and the lifting assembly 630 is located below the platform body 610. The carrier 620 includes a bottom plate 621, a guide bar 622 and a second support plate 623. The bottom plate 621 is detachably fixed to the platform body 610. The guide bar 622 is vertically connected to the bottom plate 621. There are multiple guide bars 622, and they are suitable for forming a receiving space. The second support plate 623 is placed on the bottom plate 621 and received in the receiving space. The second support plate 623 can be lifted and lowered in the vertical direction under the guidance of the guide bar 622. The receiving space is suitable for stacking and receiving a plurality of battery cells 400 supported on the second support plate 623. The lifting assembly 630 includes a lifting module 631 and a lifting block 632 transmission-connected to the lifting module 631. The lifting block 632 is suitable for lifting the second support plate 623 through the platform 610 under the drive of the lifting module 631, so that the topmost battery cell 400 is at a preset height, which is convenient for the handling robot 300 to pick up materials.

[0059] Since the handling robot 300 can carry two battery cells 400 at a time, preferably, in this embodiment, the carrier 620 also includes a plurality of partition bars 624 vertically connected to the base plate 621, and the partition bars 624 are suitable for dividing the receiving space into two receiving portions 625 arranged side by side along the length direction of the first conveyor line 100 and / or the second conveyor line 200, and the two receiving portions 625 are both suitable for receiving and positioning the battery cells 400.
