[0049] In order to further understand the content, features and effects of the invention of this application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0050] Example

[0051] In the cylindrical battery production line, after the flattening process of the battery cell tabs is completed, the battery cell needs to be shelled;

[0052] However, in the current cylindrical battery production line, a large amount of manual operation is required in the battery shelling process, especially the loading of battery cells, loading of steel shells and subsequent unloading of batteries; this makes the production cycle too long, the overall production efficiency is low, and the investment in human resources is increased;

[0053] In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0054] For details, see Figure 1-9 , this embodiment provides a battery cell shelling device, including a first conveying device 11 and a second conveying device 12;

[0055] Specifically, the first conveying device 11 conveys the battery cell 14 along the first direction; the second conveying device 12 conveys the steel shell 13 along the first direction;

[0056] Furthermore, a steel shell feeding device 20 is provided at the starting end of the second conveying device 12;

[0057] Furthermore, a battery cell shelling device 30 is provided at the conveying end of the first conveying device 11;

[0058] The battery cell shell insertion device 30 pushes the battery cell 14 into the steel shell 13 along the second direction;

[0059] In some embodiments, the first direction and the second direction are perpendicular to each other; wherein the second direction can be understood as being parallel to the axial direction of the battery core 14 or the steel shell 13 .

[0060] It should be further explained that the conventional method of inserting the battery cell 14 into the shell is mostly vertical insertion, that is, the battery cell 14 is clamped by a robot and inserted into the shell. This method has the following disadvantages:

[0061] (1) Clamping the battery cell 14 in a clamping manner will cause a certain degree of damage to the battery cell 14, especially for a battery cell 14 with a larger volume, which is generally heavier, so a greater clamping force is required to clamp the battery cell 14, thereby increasing the risk of affecting the quality of the battery cell 14;

[0062] (2) The vertically placed battery cell 14 is not stable enough during the transfer process, and requires a large number of fixing jigs or fixing mechanisms to assist in its stable transportation, which results in a complex conveying structure and affects production efficiency to a certain extent;

[0063] (3) When inserting the battery into the shell vertically, the robot arm needs to be inserted deeper into the shell. Otherwise, if the battery cell 14 is allowed to fall by its own gravity, there is a risk of damage to the battery cell 14 to a certain extent, especially for the battery cell 14 with a larger volume and mass;

[0064] For details, see Figure 4-6 The battery cell shell insertion device 30 includes a frame 31, a battery cell 14 shell insertion track; a battery cell pushing component 34 and a first driving group 33;

[0065] Specifically, the battery cell 14 shell entry track is provided between the first conveying device 11 and the second conveying device 12, and the extension direction of the battery cell 14 shell entry track is parallel to the second direction;

[0066] See also Figure 4 The battery cell 14 shell entry track is formed with a slot body having two ports, one of which faces the first conveying device 11, and the other faces the second conveying device 12; it can be further understood that one port is aligned with the battery cell 14, and the other port is aligned with the steel shell 13, and the battery cell pushing component 34 is lowered under the action of the first driving group 33 to push the battery cell 14 into the battery cell 14 shell entry track, and is guided by the battery cell 14 shell entry track to pass into the steel shell 13, thereby realizing the battery cell 14 shell entry.

[0067] Specifically, the first driving group 33 is disposed on the frame 31 and drives the battery cell pushing assembly 34 to move along the second direction.

[0068] For further information, see Figure 1 and Figure 3 , the first conveying device 11 and the second conveying device 12 both include a jig return track 111 and a plurality of second jigs 112 disposed on the jig return track 111;

[0069] Furthermore, a third groove 1121 is opened on the second fixture 112; the battery cell 14 or the steel shell 13 is placed horizontally on the third groove 1121. Due to the horizontal placement, the center of gravity of the battery cell 14 or the steel shell 13 is lower, and the overall transmission stability is better. The transportation is achieved by cooperating with the fixture return track 111 and the second fixture 112, and there is no need to add other auxiliary fixing mechanisms in the middle. The overall structure is simple, but it can ensure the stable transportation of materials.

[0070] Furthermore, in the above scheme, the present application adopts a horizontal manner to achieve the entry of the battery cell 14 into the shell, and the battery cell 14 is pushed into the steel shell 13 by pushing one end of the battery cell 14. Compared with the traditional method, the battery loss is lower and the battery cell 14 can be more effectively protected, thereby ensuring product quality and reducing the risk of product damage.

[0071] Furthermore, by adopting the lateral pushing method, the battery cell 14 is not affected by gravity when entering the shell, and the battery cell 14 will not fall freely. The movement of the battery cell 14 when entering the shell is realized by the battery cell shell insertion device 30, so that the shell insertion process is more controllable.

[0072] For details, see Figure 4-6 , further comprising a first fixing plate 331 disposed at the driving end of the first driving group 33;

[0073] Furthermore, the battery cell pushing assembly 34 includes a plurality of groups, and the plurality of groups of the battery cell pushing assembly 34 are arranged side by side on the first fixing plate 331;

[0074] In the above scheme, several groups of battery cell pushing components 34 cooperate with each other, and the first driving group 33 can drive multiple groups of battery cell pushing components 34 to move at the same time, so that multiple groups of battery cells 14 can be shelled at one time, thereby improving production efficiency.

[0075] Specifically, the battery cell pushing assembly 34 includes a second fixing plate 341, a pushing rod 342 disposed on the second fixing plate 341, and a pushing head 343 disposed at the end of the pushing rod 342;

[0076] In the above solution, the movement of the second fixing plate 341 drives the push rod 342 and the push head 343 to move, and the push head 343 acts on the end of the battery cell 14 to drive the battery cell 14 to move and enter the shell;

[0077] Furthermore, the pusher head 343 is made of a silicone insulating material, which not only has an insulating effect, but also has a certain buffering effect, thereby reducing the risk of damaging the battery cell 14 when the pusher head 343 acts on the battery cell 14.

[0078] Specifically, the battery cell pushing assembly 34 further includes a third fixing plate 344, and the second fixing plate 341 is slidably disposed on the third fixing plate 344 along the second direction;

[0079] Furthermore, an elastic component 345 is provided on the third fixing plate 344 or the second fixing plate 341 to limit the second fixing plate 341 from approaching the battery cell 14 shell entry track along the second direction;

[0080] Furthermore, the elastic component 345 can be arranged in a variety of ways. In one embodiment, Figure 4 As shown, a fixing column 346 is provided on the third fixing plate 344, one end of the elastic component 345 is connected to the fixing column 346, and the other end is connected to the second fixing plate 341;

[0081] Further, the third fixing plate 344 is disposed on the first fixing plate 331;

[0082] In the above scheme, when the first driving group 33 drives the third fixed plate 344 to move, the second fixed plate 341 will also move accordingly. The elastic component 345 can play a buffering role when the push head 343 on the second fixed plate 341 contacts the battery cell 14, thereby reducing the impact of the push head 343 on the battery cell 14.

[0083] Furthermore, a photoelectric sensor 347 is provided on the third fixing plate 344, and a stopper cooperating with the photoelectric sensor 347 is provided on the second fixing plate 341;

[0084] In the above scheme, when it is difficult for the battery cell 14 to enter the shell, the push head 343 encounters resistance and cannot move forward further. At this time, since the second fixed plate 341 and the first fixed plate 331 are slidingly arranged, they can produce relative sliding. When relative sliding occurs, the block on the second fixed plate 341 will pass through the photoelectric sensor 347, thereby sending out an alarm signal. In this way, the process of the battery cell 14 entering the shell can be monitored in a timely and effective manner to avoid jamming.

[0085] Specifically, a steel shell fixing device 35 is provided at the location of the battery cell shell insertion device 30;

[0086] Furthermore, the steel shell fixing device 35 clamps or presses the steel shell 13 so that the steel shell 13 and the second conveying device 12 remain relatively still;

[0087] See also Figure 5 , the steel shell fixing device 35 includes a first mounting plate 351, a fourth driving group 352, a second mounting plate 353 and a pressing block 354;

[0088] Among them, a plurality of pressing blocks 354 are arranged side by side on the second mounting plate 353, the second mounting plate 353 is arranged at the driving end of the fourth driving group 352, the fourth driving group 352 is arranged on the first mounting plate 351, and the first mounting plate 351 can be arranged on the frame 31 or independently fixedly arranged on a single supporting mechanism;

[0089] In the above scheme, the fourth driving group drives the second mounting plate 353 to rise and fall, thereby driving the pressing block 354 to rise and fall, and the pressing block 354 descends and presses the steel shell 13 on the second fixture 112 to achieve its stable placement, thereby ensuring the placement stability of the steel shell 13 when the battery cell 14 is subsequently put into the shell, thereby improving the stability of the battery cell 14 being put into the shell.

[0090] Specifically, the steel shell feeding device 20 includes a storage box 21 and a feeding assembly;

[0091] Specifically, the storage box 21 is used to store the steel shell 13;

[0092] Furthermore, the loading assembly 22 includes a first fixture 221 and a pushing module 222;

[0093] The first fixture 221 is formed with a first groove 2211, and the steel shell 13 in the storage box 21 falls into the first groove 2211, and the pushing module 222 pushes the steel shell 13 in the first groove 2211 toward the second conveying device 12 along the second direction;

[0094] For further information, see Figure 7-8 A material unloading inclined plate 211 is provided on the material storage box 21, and an opening is formed between the material unloading inclined plate 211 and the side wall of the material storage box 21. The size of the opening is adapted to the diameter of the steel shell 13, and is just enough for a single steel shell 13 to pass through. The steel shell 13 slides into the first groove 2211 through the opening under the action of gravity. The first groove 2211 limits the steel shell 13, and subsequently the steel shell 13 is pushed toward the second conveying device 12 through the action of the pushing module 222.

[0095] Furthermore, the first fixture 221 is provided with a clearance groove 2212 communicating with the first groove 2211;

[0096] Specifically, the pusher module 222 includes a push rod 2223, a second drive group 2222 for driving the push rod 2223 to move up and down, and a third drive group 2221 for driving the second drive group 2222 and the push rod 2223 to move along the second direction;

[0097] When the push rod 2223 moves along the second direction, it passes through the avoidance groove 2212 and abuts against one end of the steel shell 13 to push the steel shell 13;

[0098] In the above scheme, when the steel shell 13 falls into the first groove 2211, the push rod 2223 moves along the second direction, acting on one end of the steel shell 13 to push it along the second direction. Due to the air-avoiding effect of the air-avoiding groove 2212, the push rod 2223 can pass freely without being hindered; when the steel shell 13 is pushed away from the first groove 2211, the next steel shell 13 enters the first groove 2211 under the action of gravity. At this time, the push rod 2223 sinks under the action of the second driving group 2222 before resetting, thereby avoiding pushing away the steel shell 13 placed in the first groove 2211 during the resetting process. After moving to the other end of the steel shell 13, the above operation is repeated to push the steel shell 13 away from the first groove 2211.

[0099] For details, see Fig. 9 , the second conveying device 12 includes a track group 45, a steel shell 13 buffer mechanism and a first transfer assembly 40;

[0100] Furthermore, the cache mechanism of the steel shell 13 is disposed on one side of the first fixture 221, and a second groove 441 communicating with the first groove 2211 is formed on the cache mechanism;

[0101] The pushing module 222 pushes the steel shell 13 in the first groove 2211 into the second groove 441 along the second direction, and the first transfer assembly 40 transfers the steel shell 13 in the second groove 441 to the track assembly 45;

[0102] In the above scheme, since there are multiple groups of mechanisms working together in one assembly line, this embodiment separates the feeding of the steel shell 13 from the conveying of the track group 45, so that the feeding process can be more stable and the phenomenon of the steel shell 13 being stuck during the feeding process can be effectively reduced;

[0103] Furthermore, the steel shell 13 is pushed from the first groove 2211 into the second groove 441 by the pusher module 222, and is further transferred to the track assembly 45 through the first transfer assembly 40;

[0104] Among them, the first transfer component 40 may include a gripper 41, a first gripper 41 drive group and a second gripper 41 drive group; wherein, the first gripper 41 drive group and the second gripper 41 drive group cooperate to realize dual-axis movement, that is, vertical and lateral movement, and the gripper 41 is used to grasp and clamp the steel shell 13, thereby realizing the transfer of the steel shell 13 under the cooperation of the three.

[0105] For further information, see Figure 1 The track group 45 includes a first track 451 and a second track 452, and a second transfer assembly is disposed on the first track 451 and the second track 452 brackets;

[0106] In the above scheme, the first transfer assembly 40 transfers the steel shell 13 to the first track 451 , and the first track 451 directionally transports the steel shell 13 close to the second track 452 . After reaching the designated position, the second transfer assembly transfers it to the first track 451 .

[0107] Specifically, a steel shell 13 coding device is provided on one side of the first track 451;

[0108] Further, the coding device of the steel shell 13 includes a laser emitting mechanism;

[0109] Furthermore, a first code scanning detection device 51 and a second code scanning detection device 52 are respectively arranged on the conveying paths of the first conveying device 11 and the second conveying device 12; and along the conveying path of the second conveying device, the second code scanning detection device 52 is arranged after the code engraving device of the steel shell 13;

[0110] In the above scheme, the first code scanning detection device 51 can identify the identification code on the battery cell 14 and upload the scanning result to the system (which can be an MES system). The steel shell 13 coding device can perform laser coding on the outer wall of the steel shell 13 and identify it through the second code scanning detection device 52, so that the battery cell 14 and the outer shell can be adapted to each other, which is convenient for subsequent unified management.

[0111] For details, see Figure 1-2 , a visual inspection mechanism 121 and an NG unloading device 122 which is in signal communication with the visual inspection mechanism 121 are sequentially arranged on the conveying path of the second conveying device 12;

[0112] In the above scheme, the visual inspection mechanism 121 can inspect the steel shell 13. If a defective steel shell 13 is detected, it will be detected by the NG unloading device 122.

[0113] For details, see Figure 1 A dust removal device 15 is provided on the conveying path of the second conveying device 12 , and the dust removal device 15 is used for removing dust from the steel shell 13 .

[0114] It should be noted that the above-mentioned driving group can be a driving mechanism such as a driving motor, a driving cylinder, etc.

[0115] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.
