Description

Technical Field

[0001] This application belongs to the field of battery cell delivery equipment, specifically relating to a battery cell extraction device. Background Technology

[0002] After the battery cells are produced, they are packed into stacking frames, with multiple cells arranged side-by-side in each frame. These frames are then stored together. For further processing, individual cells need to be separated from the frames and neatly arranged before proceeding to the next process step.

[0003] The extraction and placement of battery cells currently rely mainly on manual operation. The gap between the battery cells and the material frame is narrow, making manual removal inconvenient. Manual placement of battery cells is time-consuming and prone to errors, consuming a lot of manpower and affecting overall production efficiency. Utility Model Content

The first conveyor belt extends along the first direction, and the multiple partition plates are spaced apart above the first conveyor belt along the second direction to form multiple feeding channels on the first conveyor belt. Each feeding channel is provided with a first motor, and a first baffle is connected to the first motor. When the first motor drives the first baffle to rise, the full-fill frame of the battery cell in the feeding channel corresponding to the first motor is conveyed by the first conveyor belt to the extraction mechanism and the unloading mechanism.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the fixed scope of the present utility model.

[0036] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0037] This utility model embodiment provides a battery cell 210 extraction device, which includes a feeding mechanism 1, an extraction mechanism 4, and an unloading mechanism 5 arranged sequentially. The feeding mechanism 1 is used to transport a full battery cell frame 200 to the extraction mechanism 4 and the unloading mechanism 5. The extraction mechanism 4 includes a support 41, a first push plate 43, and an extraction component 42. The support 41 has a movable platform 411 extending along a first direction, adjacent to the feeding mechanism 1. The first push plate 43 and the extraction component 42 are both movably connected to the support 41, and the extraction component 42 is used to extract the battery cell 210. The battery cell 210 in the full battery cell frame 200 conveyed by mechanism 1 is extracted onto the moving platform 411. The first push plate 43 is used to push the battery cell 210 along the first direction to the processing position. The unloading mechanism 5 includes a mounting frame 51, a second push plate 52 and a storage platform 53. The storage platform 53 is adjacent to the loading mechanism 1. One end of the mounting frame 51 is connected to the storage platform 53, and the other end of the mounting frame 51 is located on the side of the conveying platform away from the storage platform 53. The second push plate 52 is movably connected to the mounting frame 51 and is used to push the empty battery cell frame 220 to the storage platform 53.

[0038] like Figure 1 As shown, the battery cell 210 extraction device in this embodiment includes a feeding mechanism 1, an extraction mechanism 4, and an unloading mechanism 5. The feeding mechanism 1 is used to sequentially transport the battery cell full frame 200 containing the battery cells 210 to the extraction mechanism 4 and the unloading mechanism 5. The extraction mechanism 4 extracts the battery cells 210 from the full frame 200 and sequentially transports them to the processing position. The battery cells 210 output by the extraction mechanism 4 are arranged in order and can directly enter the next process for testing, grading, and other processing. After the battery cells 210 are extracted, the remaining empty frames 220 continue to be transported to the unloading mechanism 5. The unloading mechanism 5 pushes out the empty frames 220 and arranges them neatly for recycling and reuse.

[0039] In practical applications, the extraction mechanism 4 and the unloading mechanism 5 are located at different positions along the movement path of the full cell frame 200, with the extraction mechanism 4 preceding the unloading mechanism 5. The extraction mechanism 4 is equipped with a moving platform 411 extending along a first direction. When the full cell frame 200 is conveyed to a position close to the moving platform 411, the extraction component 42 of the extraction mechanism 4 moves to the feeding mechanism 1, grabbing the cells 210 from the full cell frame 200. Then, it moves away from the feeding mechanism 1, extracting the cells 210 onto the moving platform 411. This process is repeated multiple times until all the cells 210 in the full cell frame 200 are extracted. The cells 210 extracted onto the moving platform 411 move from one end of the moving platform 411 to the other end under the action of the first push plate 43. The end of the moving platform 411 is connected to the next workstation, and the cells 210 enter the processing position of the next workstation via the moving platform 411.

[0040] After all the battery cells 210 have been extracted, the remaining empty material frame 220 is on the feeding mechanism 1. After detecting that all the battery cells 210 in the full battery cell frame 200 have been extracted, the full battery cell frame 200 continues to be conveyed forward. The empty material frame 220 is pushed by the full battery cell frame 200 coming from behind, and moves to a position close to the unloading mechanism 5. The second push plate 52 of the unloading mechanism 5 pushes the empty material frame 220 along the mounting frame 51 to the storage platform 53.

[0041] In addition, in some optional embodiments, the feeding mechanism 1 includes: a first conveyor belt 11, a plurality of partition plates 12 and a plurality of first motors 13. The first conveyor belt 11 extends along a first direction, and the plurality of partition plates 12 are spaced apart above the first conveyor belt 11 along a second direction to form a plurality of feeding channels on the first conveyor belt 11. Each feeding channel is provided with a first motor 13, and a first baffle 14 is connected to the first motor 13. When the first motor 13 drives the first baffle 14 to be lifted, the full cell frame 200 in the feeding channel corresponding to the first motor 13 is transported by the first conveyor belt 11 to the extraction mechanism 4 and the unloading mechanism 5.

[0042] like Figure 2 As shown, the loading mechanism relies on a drive motor and chain to move the first conveyor belt 11, realizing the function of transporting the full battery cell frames 200. The first conveyor belt 11 extends along a first direction, and multiple partition plates 12 are spaced apart along a second direction. The first direction is perpendicular to the second direction. The length of the partition plates 12 is at least equal to the length of the first conveyor belt 11, so that the space on the first conveyor belt 11 is divided into multiple parallel loading channels, and the full battery cell frames 200 are arranged in rows in multiple loading channels.

[0043] Under the continuous action of the first conveyor belt 11, the full-load frames 200 of the battery cells in each feeding channel tend to move forward. The outlet of the feeding channel is equipped with a first motor 13 and a first baffle 14 that can move up and down. The first baffle 14 is connected below the first motor 13. When the first motor 13 descends until the first baffle 14 is directly in front of the full-load frames 200 of the battery cells, the first baffle 14 will block the movement of the full-load frames 200 of the battery cells. When the first motor 13 rises, the first baffle 14 rises accordingly, allowing the full-load frames 200 of the battery cells to pass smoothly and enter the next stage. The first motors 13 on multiple feeding channels rise in turn in sequence, so that the full-load frames 200 of the battery cells are output in an orderly manner.

[0044] The distance between two adjacent isolation plates 12 is adapted to the size of the full cell frame 200, allowing the full cell frame 200 to move in the feeding channel without the cells 210 falling out. It should be noted that, for reference... Figure 9 - Figure 10 In this embodiment, the battery cell full-fill frame 200 is placed on its side, with the opening of the battery cell full-fill frame 200 facing the side, which facilitates the extraction member 42 in the extraction mechanism 4 to extract the battery cell 210 from the side. When the battery cell full-fill frame 200 is placed in the feeding channel, the opening of the battery cell full-fill frame 200 faces the isolation plate 12, and the exposed battery cell 210 in the opening will not fall off during movement under the constraint of the isolation plate 12.

[0045] In addition, in some optional embodiments, the battery cell 210 extraction device further includes a first transfer mechanism 2 and a second transfer mechanism 3. The first transfer mechanism 2 is disposed between the feeding mechanism 1 and the second transfer mechanism 3, and the second transfer mechanism 3 is connected to the first transfer mechanism 2, the extraction mechanism 4 and the unloading mechanism respectively. The first transfer mechanism 2 includes a slide rail 21 and a sliding seat 22. The slide rail 21 is adjacent to the first conveyor belt 11 and is opposite to multiple feeding channels. The sliding seat 22 is movably connected to the slide rail 21 and can slide along the slide rail 21. The sliding seat 22 is provided with a second conveyor belt 221 extending in a first direction. When the sliding seat 22 is opposite to a feeding channel, the first motor 13 corresponding to the feeding channel drives the first baffle 14 to lift, and the full battery cell frame 200 in the feeding channel is transported by the first conveyor belt 11 to the second conveyor belt 221.

[0046] The first transfer mechanism 2 and the second transfer mechanism realize the single loading of the full battery cell frame 200, and sequentially transport the full battery cell frames 200 output from multiple loading channels to the extraction mechanism 4 and the unloading mechanism 5. Figure 3As shown, the first transfer mechanism 2 includes a slide rail 21 and a sliding seat 22 movably connected to the slide rail 21. The slide rail 21 extends along the second direction, close to the output end of the first conveyor belt 11, and is opposite to the outlet of the multiple feeding channels. The sliding seat 22 reciprocates along the slide rail 21. A second conveyor belt 221 extending along the first direction is provided on the sliding seat 22.

[0047] The sliding seat 22 moves along the second direction and stops in front of the exit of one of the feeding channels. The first motor 13 and the first baffle 14 are raised, and the full battery cell frame 200 moves along the first direction onto the sliding seat 22 under the action of the first conveyor belt 11. After the full battery cell frame 200 moves into place, the first motor 13 and the first baffle 14 are lowered to continue blocking the movement of the rear full battery cell frame 200. The sliding seat 22 then moves along the second direction to the position where the slide rail 21 is connected to the second transfer mechanism 3 and remains stationary. The second conveyor belt 221 starts, and the full battery cell frame 200 on the sliding seat 22 is transported along the first direction to the second transfer mechanism 3 under the action of the second conveyor belt 221. After the full battery cell frame 200 is completely detached from the sliding seat 22, the second conveyor belt 221 stops, and the sliding seat 22 then returns along the second direction for the next transport. The sliding seat 22 moves back and forth multiple times between the feeding channel of the feeding mechanism 1 and the second transfer mechanism 3 until all the battery cell full frame 200 on the first conveyor belt 11 is transported to the second transfer mechanism 3.

[0048] The sliding seat 22 transports only one full battery cell frame 200 at a time, enabling the full battery cell frames 200 to be loaded sequentially. The full battery cell frames 200 transported to the second transfer mechanism 3 are automatically arranged in a row, facilitating the sequential processing of each full battery cell frame 200 by the extraction mechanism 4 in front, without the need for manual arrangement. The transport sequence of the full battery cell frames 200 in each loading channel can be set according to the needs of the sliding seat 22's position and sequence for each round trip. For ease of management, transport usually starts from the outermost loading channel, and the full battery cell frames 200 in each loading channel are transported to the second transfer mechanism 3 in sequence.

[0049] In addition, in some optional embodiments, the sliding seat 22 is also provided with a fixing device 222, which has a first opening and a second opening facing each other. The first opening faces the first conveyor belt 11 and the second opening faces away from the first conveyor belt 11. The fixing device 222 is used to constrain the full cell frame 200.

[0050] The first and second openings of the fixing device 222 form a channel along the first direction, allowing the full-filled battery cell frame 200 to move into the fixing device 222 on the sliding seat 22 under the action of the first conveyor belt 11. When the sliding seat 22 moves along the slide rail 21 along the second direction, the full-filled battery cell frame 200 tends to move. The channel is adapted to the size of the full-filled battery cell frame 200, constraining the lateral displacement of the full-filled battery cell frame 200 without affecting its movement. As described in the previous embodiment, the opening of the full-filled battery cell frame 200 is located on the side. When the sliding seat 22 moves, the fixing device 222 restricts the movement of the battery cell 210 in the side opening, preventing the battery cell 210 from falling off during movement.

[0051] Additionally, in some alternative embodiments, such as Figure 5 As shown, the second transfer mechanism 3 includes a first stack 31, a second stack 32 and a third stack 33 connected in sequence. The first stack 31 is adjacent to the slide rail 21, the second stack 32 is adjacent to the moving platform 411, and the third stack 33 is adjacent to the storage platform 53. When the sliding seat 22 slides to be adjacent to the first stack 31, the full battery cell frame 200 is transported to the first stack 31 by the second conveyor belt 221.

[0052] The first stack 31 is connected to the slide rail 21 and receives the full battery cell frame 200 conveyed from the sliding seat 22. The second stack 32 is adjacent to the moving platform 411, where the full battery cell frame 200 is used to extract the battery cell 210. The third stack 33 is connected to the storage platform 53, where the empty battery cell frame 220 is pushed out to the storage platform 53. The first stack 31, second stack 32, and third stack 33 are equipped with ball bearings 37 to reduce resistance during movement.

[0053] Furthermore, the first stack 31, the second stack 32, and the third stack 33 all extend along the first direction. The full cell frame 200 on the sliding seat 22 enters the first stack 31 along the first direction under the drive of the second conveyor belt 221. The moving platform 411 is arranged side by side with the second stack 32. The side opening of the full cell frame 200 faces the moving platform 411, so that after the extraction component 42 extracts the cell 210 onto the moving platform 411, the cell 210 moves along the moving platform 411 to the next processing position.

[0054] In addition, in some optional embodiments, the second transfer mechanism 3 further includes a second motor 34, which is located above the first stack 31 near the slide rail 21. A third push plate 35 is connected to the second motor 34. The second motor 34 and the third push plate 35 are used to push the full cell frame 200 to move along the first stack 31, the second stack 32 and the third stack 33.

[0055] In this embodiment, the second motor 34 includes a first cylinder 341 and a second cylinder 342. The first cylinder 341 is positioned above the first stack 31 along its extension direction. The extension and retraction of the first cylinder 341 are along the extension direction of the first stack 31. In specific applications, the first stack 31 is typically configured to extend along a first direction, and the first cylinder 341 extends and retracts along the first direction. One end of the first cylinder 341 near the slide rail 21 is connected to the second cylinder 342. When the first cylinder 341 extends and retracts, it drives the second cylinder 342 to move above the first stack 31. The extension and retraction direction of the second cylinder 342 is along the height direction, and a third push plate 35 is connected below the second cylinder 342. When the second cylinder 342 drives the third push plate 35 to descend to a position opposite to the full cell frame 200, the third push plate 35 pushes the full cell frame 200 to move as the first cylinder 341 retracts.

[0056] The first cylinder 341 and the second cylinder 342 are both in the retracted state by default. At this time, the third push plate 35 is raised, which will not affect the movement of the full cell frame 200 on the second transfer mechanism 3. When the full cell frame 200 on the second stack 32 has finished extracting the cell 210 and a new full cell frame 200 needs to be transported for extracting the cell 210, the second conveyor belt 221 is started to transport the full cell frame 200 to the first stack 31. After the full-fill frame 200 is in position, the first cylinder 341 extends, and the second cylinder 342 moves to a position above the first walkway 31 near the slide rail 21. The second cylinder 342 extends, and the third push plate 35 descends to a height that contacts the full-fill frame 200. Then, the first cylinder 341 retracts, and the third push plate 35 contacts the full-fill frame 200 and pushes it to the second walkway 32. Simultaneously, the empty frame 220, which has already been extracted, is pushed to the third walkway 33. After the full-fill frame 200 is in position, the second cylinder 342 retracts, and both the first and second cylinders 341 and 342 return to their retracted state. The full-fill frame 200, now on the second walkway 32, begins extracting the battery cells 210, while the empty frame 220 on the third walkway 33 is pushed to the storage platform 53 for placement. The first cylinder 341 and the second cylinder 342 reciprocate according to the above steps, continuously conveying the full battery cell frame 200 forward.

[0057] In addition, in some optional embodiments, fixing plates 36 are provided on both sides of the first stack 31 and the second stack 32, and the fixing plates 36 are used to constrain the full cell frame 200.

[0058] refer to Figure 4 , Figure 9 and Figure 10As described in the aforementioned embodiments, the battery cell full frame 200 is placed on its side during movement, with the opening facing the side. The fixing plates 36 on both sides of the first stack 31 and the second stack 32 ensure that even if the equipment malfunctions or is impacted by external forces, affecting the normal movement of the battery cell full frame 200, the battery cell full frame 200 will not deviate from the first stack 31 and the second stack 32. On the other hand, it prevents the battery cells 220 in the battery cell full frame 200 from falling out.

[0059] In some alternative embodiments, a discharge port 361 is provided on the fixed plate 36 facing the mobile platform 411, and the discharge port 361 is disposed opposite to the extraction member 42.

[0060] like Figure 4 As shown, a discharge port 361 is provided on the fixed plate 36 between the second stack 32 and the moving platform 411, and the discharge port 361 is arranged opposite to the extraction component 42. When placing the full battery cell frame 200, the side opening of the full battery cell frame 200 is placed facing the discharge port 361, so that when the full battery cell frame 200 reaches the second stack 32, the battery cells 210 in the full battery cell frame 200 are exposed in the discharge port 361. The extraction component 42 moves towards the discharge port 361, grabs the battery cells 210, and then moves back to its original position, placing the battery cells 210 on the moving platform 411. The second pusher plate 52 moves from one end of the moving platform 411 to the other end, pushing the battery cells 210 one by one to the processing position.

[0061] The discharge port 361 is located at the bottom of the fixed plate 36, and its size is just enough to expose all the bottom layer of battery cells 210. The extraction component 42 can smoothly extract the battery cells 210 from the discharge port 361 onto the moving platform 411, ensuring that only one row of battery cells 210 is extracted at a time. This row of battery cells 210 is arranged on the moving platform 411 along the extension direction of the moving platform 411, i.e., the first direction, and enters the next process one by one under the push of the first push plate 43, realizing the individual and orderly online production of battery cells 210. After the bottom layer of battery cells 210 is extracted, the upper layer of battery cells 210 fall under the action of gravity and are exposed to the discharge port 361. The extraction mechanism 4 repeats the above operation until all battery cells 210 in the battery cell full frame 200 are extracted.

[0062] In some alternative embodiments, the extraction component 42 includes a connected third motor 421 and a magnetic component 422. The third motor 421 is movably connected to the moving platform 411, and the magnetic component 422 is disposed opposite to the discharge port 361. The third motor 421 is used to drive the magnetic component 422 to move closer to or away from the discharge port 361.

[0063] The third motor 421 is located on the side of the moving platform 411 away from the second stack 32. A magnetic element 422 is provided at the front end of the third motor 421. When the third motor 421 extends, the magnetic element 422 attracts the battery cell 210 in the second stack 32. When the third motor 421 retracts, the magnetic element 422 drives the battery cell 210 to detach from the battery cell full frame 200 and place it on the moving platform 411. The first pusher plate 43 moves from one end of the moving platform 411 to the other end, pushing the battery cell 210 to detach from the magnetic element 422 and pushing the battery cell 210 along the moving platform 411 to the processing position for detection, sorting, and other processing.

[0064] In some alternative embodiments, the mobile platform 411 is provided with an adhesive strip 412 along the first direction.

[0065] An adhesive strip 412 is provided on the mobile platform 411 along the movement direction of the battery cell 210. The adhesive strip 412 plays a buffering and protective role during the movement of the battery cell 210, protecting the battery cell 210 from being affected by the metal frame of the equipment.

[0066] In some alternative embodiments, the extraction mechanism 4 also includes a discharge ramp 44, which is connected to the mobile platform 411.

[0067] The mobile platform 411 and the discharge ramp 44 are connected in the first direction. The first push plate 43 moves in the direction of the discharge ramp 44 to push the battery cell 210 into the discharge ramp 44. The discharge ramp 44 is a flat ramp. The battery cell 210 falls down along the discharge ramp 44 in sequence by its own gravity and flows into the battery cell 210 detection and grading process.

[0068] In some alternative embodiments, the storage platform 53 is provided with a position sensor and a fourth pusher plate 54. The second pusher plate 52 moves along a second direction, and the fourth pusher plate 54 moves along a first direction. When the position sensor detects that the battery cell full frame 200 pushed by the second pusher plate 52 has been stacked to the target position, the fourth pusher plate 54 pushes the battery cell full frame 200 to move along the first direction to move away from the target position.

[0069] The full cell frame 200 on the first stack 31 is pushed to the second stack 32 by the fourth push plate 54. At the same time, the empty cell frame 220 in the second stack 32 is pushed to the third stack 33. The empty cell frame 220 is transported to the storage platform 53 by the second push plate 52.

[0070] like Figure 7As shown, the receiving platform 53 of the unloading mechanism 5 is also equipped with an empty material frame baffle 55. When the position sensor detects that the empty material frames 220 have piled up to the empty material frame baffle 55, it means that the empty material frames 220 have filled a row and reached the target position. The fourth push plate 54 pushes this row of empty material frames 220 forward to move away from the target position. The empty material frames 220 in front of the second baffle are cleared away, and the empty material frames 220 can continue to be moved until a row is filled. The second push plate 52 and the fourth push plate 54 cooperate. The second push plate 52 piles up the empty material frames 220 along the second direction, and the fourth push plate 54 piles up the empty material frames 220 along the first direction, so that the empty material frames 220 are distributed in an array on the receiving platform 53. When a certain number of empty material frames 220 are stacked, they are manually moved away, realizing the unloading of the empty material frames 220. Universal wheels can be installed under the receiving platform 53 to facilitate the transfer and handling of materials. The movement of the third baffle on the storage platform 53 can be achieved through the slide rail 21 structure, and the fourth push plate 54 can slide along the track 56 set on the storage platform 53.

[0071] In this embodiment, the movement path of the full cell frame 200 is as follows: the full cell frame 200 is transported by the first conveyor belt 11 along the first direction to the sliding seat 22, the sliding seat 22 moves along the second direction to the second transfer mechanism 3, and the second conveyor belt 221 transports the full cell frame 200 along the first direction to the first stack 31, and then it is extracted and unloaded. The second motor 34 and the second baffle push the full battery cell frame 200 to move along the first direction to the second staircase 32. On the second staircase 32, the battery cell 210 and the frame 220 separate. The battery cell 210 is extracted onto the moving platform 411, which is parallel to the second staircase 32. The first pusher 43 pushes the battery cell 210 along the moving platform 411 onto the discharge ramp 44 and slides it into the next station. The remaining empty frame 220 on the second staircase 32 is pushed by the incoming material from behind along the first direction to the third staircase 33. The second pusher 52 pushes it along the second direction onto the storage platform 53. After a row is filled, the fourth pusher 54 pushes it forward along the first direction, stacking it neatly and waiting for the staff to move it away.

[0072] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
