Description

[0002] The manufacturing process of battery cells involves multiple steps. With the rapid development of the power battery industry, higher demands are being placed on the efficiency of battery cell manufacturing.

[0003] In traditional battery cell assembly processes, incoming battery cells need to be pushed into the battery cell housing. Four housings (one for each cell and one for the housing) need to be processed at a time, limiting the quantity and slowing the cycle time. This is incompatible with cost and efficiency control, and puts the process at a competitive disadvantage in the market. Furthermore, waiting for materials before housing and cell housing assembly wastes time and further slows the cycle time, again failing to meet cost and efficiency control requirements and resulting in a lack of competitive advantage in the market.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0048] The following is combined with Figure 1 The present invention describes a battery cell loading system for implementing a loading process. The battery cell loading system includes: a battery cell conveying line 1, a housing conveying line, and a loading turret 4.

[0049] like Figure 2 As shown, the casing turret 4 includes a first turret device and multiple casing insertion devices 45. The multiple casing insertion devices 45 are respectively arranged around the circumference of the first turret device. The first turret device has a cell loading station, a casing loading station, and a casing-inserting cell unloading station around its circumference. The casing insertion device 45 is used to guide the cell into the casing, and when it is in the casing-inserting cell unloading station, it unloads the cell after it has been inserted into the casing.

[0050] In this embodiment, the cell conveying line 1 is used to convey the cells to the casing insertion device 45. The cell conveying line 1 is arranged opposite to the cell loading station. The cell conveying line 1 feeds the casing insertion device 45 at the cell loading station, thereby conveying the cells (wound cores) to the casing insertion device 45. The casing conveying line is used to convey the casings to the casing insertion device 45.

[0051] In the operation of the battery cell loading system provided in this embodiment, the battery cell conveying line 1 transports the battery cell to the loading device 45, the housing conveying line transports the housing to the loading device 45, the loading device 45 guides the battery cell into the housing, and unloads the loaded battery cell.

[0052] The battery cell loading system provided by this invention includes a battery cell conveying line, a housing conveying line, and a loading turret. The loading turret comprises a first turret device and multiple loading devices. The multiple loading devices are respectively arranged circumferentially along the first turret device. The battery cell conveying line is used to transport the battery cells to the loading devices; the housing conveying line is used to transport the housings to the loading devices. The loading devices are used to guide the battery cells into the housings and unload the loaded battery cells. The entire line utilizes a turret-type modular design, resulting in high mechanical transmission efficiency, unlimited incoming material quantity, and reduced waiting time for each process, thus improving loading efficiency. Compared to existing loading processes, this invention can load multiple battery cells simultaneously, improving loading efficiency while ensuring loading quality.

[0053] In one embodiment, a housing conveyor line is used to transport housings to the housing loading device 45. Two housing conveyor lines are provided: a first housing conveyor line 2 and a second housing conveyor line 3. Correspondingly, a housing loading device 5 is provided between the first housing conveyor line 2 and the second housing conveyor line 3. The housing loading device 5 is used to transport housings from the first housing conveyor line 2 to the second housing conveyor line 3. That is, the housing loading device 5 acts as a transfer component between the first housing conveyor line 2 and the second housing conveyor line 3, and scans the housings during the transfer process. The housing loading device 5 confirms the housing number by scanning the code, and cleans the housings after confirming the number to prevent dust in the housings from affecting subsequent processes. The second housing conveyor line 3 is used to transport housings to the housing loading device 45. The second housing conveyor line 3 is arranged opposite to the housing loading station, and the second housing conveyor line 3 loads housings onto the housing loading device 45 at the housing loading station, thereby transporting the housings to the housing loading device 45.

[0054] Specifically, during the operation of the battery cell loading system, the housing loading device 5 transports the housings from the first housing conveyor line 2 to the second housing conveyor line 3, scanning and cleaning the housings during the transport process. After scanning and cleaning, the housings on the second housing conveyor line 3 are transported to the loading device 45. Simultaneously, the battery cell conveyor line 1 transports the battery cells, loading them onto the loading device 45 at the battery cell loading station. Thus, the loading device 45 simultaneously houses both the battery cells and the housings. The loading device 45 guides the battery cells into the housings and unloads the loaded battery cells when it is at the unloading station. Throughout the process, each loading device 45 independently completes the loading of different battery cells, improving loading efficiency while ensuring loading quality.

[0055] Based on the above embodiments, such as Figure 1 and Figure 3 As shown, the battery cell loading system also includes: a cup loading turret 6, a cup loading conveyor line 7, and a discharge conveyor line 8.

[0056] The cup-feeding turret 6 includes a second turret device 61 and multiple cup-feeding devices 62. The multiple cup-feeding devices 62 are arranged circumferentially along the second turret device 61, which has a battery cell loading station, a cup-feeding station, and a cup-feeding station along its circumference. The cup-feeding devices 62 are used to guide the battery cells into the cups, and when the cup-feeding devices 62 are in the cup-feeding station, they unload the battery cells from the cups.

[0057] In this embodiment, the cup-holding conveyor line 7 is arranged opposite to the cup-holding loading station to load the cup-holding device 62 at the cup-holding loading station, thereby guiding the cups into the cup-holding device 62. The unloading conveyor line 8 is used to transfer the unloaded battery cells. The unloading conveyor line 8 is arranged opposite to the cup-holding battery cell unloading station to unload the cup-holding device 62 at the cup-holding battery cell unloading station, thereby directionally conveying the battery cells that have been introduced into the cups.

[0058] In this embodiment, the battery cell loading system utilizes a housing feeding device 5 to transport housings from the first housing conveyor line 2 to the second housing conveyor line 3, scanning and cleaning the housings during the transport process. After scanning and cleaning, the housings on the second housing conveyor line 3 are transported to the loading device 45. Simultaneously, the battery cell conveyor line 1 transports battery cells to the loading device 45 at the battery cell feeding station. Thus, the loading device 45 simultaneously houses both battery cells and housings. The loading device 45 guides the battery cells into the housings and unloads the loaded battery cells when it is at the unloading station. Throughout the process, each loading device 45 independently completes the loading of different battery cells, improving loading efficiency while ensuring loading quality.

[0059] After the casing is installed, the casing installation device 45 can guide the casing-installed battery cell to the cup-feeding device 62 via the conveyor line. At the same time, the empty cup on the casing installation device 45 can enter the cup-feeding conveyor line 7 via the empty cup conveyor line 11. The cup-feeding conveyor line 7 feeds the cup-feeding device 62, which is in the cup-feeding station, and can guide the cup to the cup-feeding device 62. The cup-feeding device 62 then places the casing-installed battery cell in the cup. When the cup-feeding device 62 is in the cup-feeding battery cell unloading station, it unloads the battery cell from the cup. The unloading conveyor line 8 completes the directional conveying of the cup and the battery cell.

[0060] To ensure quality throughout the entire processing, the cell loading system also includes: NG conveyor line 9 and sorting device 10.

[0061] The sorting device 10 is provided with a first station and a second station. The sorting device 10 is set opposite to the cell unloading station of the cup-into-cup turret. The unloading conveyor line 8 is set opposite to the first station, and the NG conveyor line 9 is set opposite to the second station. The sorting device 10 is used to sort the cells and cups when the cup-into-cup device 62 is at the cell unloading station. Qualified cells and cups are conveyed to the unloading conveyor line 8 through the first station, and unqualified cells and cups are conveyed to the NG conveyor line 9 through the second station.

[0062] Specifically, when the cup-feeding device 62 is at the cup-feeding cell unloading station, the cells are unloaded from the cup. After unloading, the sorting device 10 sorts the cells and cups. Qualified cells and cups are transported to the unloading conveyor line 8 through the first station, while unqualified cells and cups are transported to the NG conveyor line 9 through the second station.

[0063] In another embodiment, such as Figure 3 As shown, the second turret device 61 includes: a second rotating component 611 and a second upper turntable 612 disposed on the second rotating component 611. The second rotating component 611 is rotatable relative to the second upper turntable 612, and the second upper turntable 612 is provided with a second upper boss. The cup-holding device 62 includes: a second base 621, a second pressing component 622, and a support component 623. The second base 621 is connected to the second rotating component 611. The second pressing component 622 is movably disposed on the second base 621 in the vertical direction, and its top is disposed on the second upper boss. The second pressing component 622 is used to attract and press down the battery cell. The support component 623 is connected to the second base 621 and is used to support the cup.

[0064] When no material is being fed, the second pressing component 622 is in the high position of the second upper boss. After the battery cell after being inserted into the casing enters the second pressing component 622, the second pressing component 622 magnetically attracts the battery cell after being inserted into the casing. The cup enters the support component 623 through the cup conveyor line 7. During the rotation of the second rotating component 611, the second pressing component 622 moves to the low position of the second upper boss and presses the battery cell down into the cup, thereby placing the battery cell after being inserted into the casing into the cup.

[0065] In one embodiment, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the turret is used to guide the battery cell 41 in the cup 43 into the housing 42. The turret includes a first turret device and a plurality of housing devices 45.

[0066] The first turret device includes a first rotating component 441 and a first upper turntable 442 and a first lower turntable 443 disposed on the first rotating component 441. The first rotating component 441 may be a rotating shaft. The first rotating component 441 can rotate relative to the first upper turntable 442 and the first lower turntable 443, that is, while the first rotating component 441 rotates, the first upper turntable 442 and the first lower turntable 443 do not rotate. The first upper turntable 442 is provided with a first upper boss (not shown), and the first lower turntable 443 is provided with a first lower boss. The first upper boss extends circumferentially along the first upper turntable 442, and similarly, the first lower boss extends circumferentially along the first lower turntable 443.

[0067] like Figure 4 and Figure 5 As shown, each housing insertion device 45 includes: a first base 451, a pressing component 452, a clamping component 453, and a lifting component 454. The first base 451 is connected to the first rotating component 441. The pressing component 452 is movably disposed on the first base 451 in the vertical direction, and the top of the pressing component 452 is disposed on the first upper boss. The clamping component 453 is connected to the first base 451, and the top of the clamping component 453 is disposed on the first upper boss. The clamping component 453 is rotatably disposed on the first base 451 and is used to clamp the housing 42. The lifting component 454 is movably disposed on the first base 451 in the vertical direction, and the bottom of the lifting component 454 is disposed on the first lower boss. The lifting component is used to lift the battery cell 41 in the cup 43.

[0068] Since the first base 451 is connected to the first rotating component 441, during the rotation of the first rotating component 441, the first rotating component 441 drives the pressing component 452, the clamping component 453 and the lifting component 454 to rotate. The pressing component 452 can slide on the first upper boss, and the clamping component 453 and the lifting component 454 can slide on the first lower boss. The pressing component 452 can press down on the housing 42, and the lifting component 454 is used to lift and raise the battery cell 41. The clamping component can cooperate to clamp the housing 42 and the entire battery cell 41 after it is installed in the housing, so that the entire housing installation device 45 can be used to complete the housing installation process of the battery cell 41.

[0069] Specifically, after the battery cell 41 is delivered from the battery cell conveyor line 1, the transfer turntable conveys the battery cell 41 to the lifting assembly 454; after the housing 42 is delivered from the second housing conveyor line 3, the transfer turntable conveys the housing 42 to the clamping assembly 453. Before the battery cell 41 enters the housing, the pressing assembly 452 is in a high position, the clamping assembly 453 is used to clamp the housing 42, and the lifting assembly 454 is in a low position, used to lift the battery cell 41. When the battery cell 41 is inserted into the casing, the pressing component 452 is in a low position to press down the casing 42 held by the clamping component 453 until the casing 42 is disengaged from the clamping component 453. At the same time, the lifting component 454 is in a high position to lift the battery cell 41, thereby completing the insertion of the battery cell 41 into the casing. After the insertion is completed, the lifting component 454 can lift the inserted battery cell 41 to the clamping component 453. The clamping component 453 rotates the inserted battery cell 41 by a preset angle to facilitate the transfer of the inserted battery cell 41. Throughout the process, each insertion device 45 independently completes the insertion of different battery cells 41 into the casing, which improves the insertion efficiency and ensures the insertion quality.

[0070] In one embodiment, such as Figure 4 and Figure 5As shown, the housing insertion device 45 also includes a guide assembly 455. The guide assembly 455 includes a guide plate 4551. The guide plate 4551 is connected to the first base 451 and is disposed between the clamping assembly 453 and the lifting assembly 454. The guide plate 4551 is provided with a guide hole 4552 for the housing 42 and the battery cell 41 to pass through.

[0071] Before the battery cell 41 is inserted into the casing, the pressing component 452 is in a high position, the clamping component 453 is used to clamp the casing 42, and the lifting component 454 is in a low position to support the battery cell 41. When the battery cell 41 is inserted into the casing, the pressing component 452 is in a low position to press down the casing 42 held by the clamping component 453, which can guide the casing 42 into the guide hole 4552 until the casing 42 is completely separated from the clamping component 453. At the same time, the lifting component 454 is in a high position to lift the battery cell 41, lifting the battery cell 41 into the guide hole 4552. Under the limiting action of the guide hole 4552, the insertion of the battery cell 41 into the casing can be completed.

[0072] In another embodiment, such as Figure 4 and Figure 5 As shown, the housing insertion device 45 also includes a limiting component 456. The limiting component 456 is used to restrict the battery cell 41 after it has been inserted into the housing. The limiting component 456 is vertically movably disposed on the first base 451, and the bottom of the limiting component 456 abuts against the first lower boss. The limiting component 456 is used to avoid the housing 42 and the battery cell 41 before the battery cell 41 is inserted into the housing, and after the battery cell 41 has been inserted into the housing, the limiting component 456 is used to restrict the movement of the battery cell 41.

[0073] Specifically, the limiting component 456 includes: a limiting member 4561, a first guide rail 4562, a first elastic member 4563, a first cam follower 4564, and a second elastic member 4565. The first guide rail 4562 is connected to the clamping component 453. The top of the limiting member 4561 is slidably disposed on the first guide rail 4562. The limiting member 4561 is connected to the clamping component 453 through the first elastic member 4563. The bottom of the limiting member 4561 is disposed on a first lower boss through the first cam follower 4564. The first cam follower 4564 is slidable in the vertical direction relative to the first base 451. The first cam follower 4564 is connected to the first base 451 through the second elastic member 4565.

[0074] In this embodiment, the limiting member 4561 is slidably disposed on the first guide rail 4562. Both the first elastic member 4563 and the second elastic member 4565 can be springs. The first elastic member 4563 is used to connect the limiting member 4561 and the clamping assembly 453 to limit the movement of the limiting member 4561 and to control the limiting member 4561 to reset after movement. The second elastic member 4565 connects the first base 451 and the first cam follower 4564 so that when the first cam follower 4564 moves on the first lower boss, the second elastic member 4565 can provide a certain buffer to the first cam follower 4564 to avoid excessive force on the limiting member 4561.

[0075] Specifically, during the movement of the limiting component 456 on the first lower protrusion, when the first cam follower 4564 moves to the low position of the first lower protrusion, the limiting member 4561 is pulled downward by the first cam follower 4564, and moves to the first end of the first guide rail 4562. At this time, the limiting member 4561 can avoid the battery cell 41 and the housing 42. When the first cam follower 4564 moves to the high position of the first lower protrusion, the limiting member 4561 is lifted upward by the first cam follower 4564, and moves to the second end of the first guide rail 4562. At this time, the limiting member 4561 blocks the guide hole 4552, thereby restricting the movement of the battery cell 41 after it is inserted into the housing.

[0076] Based on the above embodiments, in an optional embodiment, such as Figure 2 and Figure 6 As shown, the first upper boss includes: a first outer upper boss and a second inner upper boss arranged coaxially. The first lower boss includes: a first outer lower boss and a second inner lower boss arranged coaxially.

[0077] The first outer upper boss and the second inner upper boss both extend circumferentially along the first upper turntable 442, and the first outer upper boss and the second inner upper boss have a height difference along their vertical lines. The first outer lower boss and the second inner lower boss extend circumferentially along the first lower turntable 443, and the first outer lower boss and the second inner lower boss have a height difference along their vertical lines. The top of the pressing component 452 is disposed on the first outer upper boss, the top of the clamping component 453 is disposed on the second inner upper boss, the bottom of the lifting component 454 is disposed on the first outer lower boss, and the bottom of the limiting component 456 is disposed on the second inner lower boss.

[0078] Before the battery cell 41 is inserted into the housing, the pressing component 452 is located at the high position of the first outer upper protrusion, the clamping component 453 clamps the housing 42, the lifting component 454 is located at the low position of the first outer lower protrusion, and the limiting component 456 is located at the low position of the second inner lower protrusion. At this time, the limiting component 456 avoids the battery cell 41 and the housing 42.

[0079] When the battery cell 41 is inserted into the casing, the pressing component 452 is located at the low position of the first outer upper protrusion. The pressing component 452 presses down on the casing 42 held by the clamping component 453 until the casing 42 is disengaged from the clamping component 453. At the same time, the lifting component is located at the high position of the first outer lower protrusion. The clamping component 453 controls the battery cell 41 to rotate 180 degrees after insertion into the casing to facilitate the transfer of the battery cell 41 after insertion. Meanwhile, the limiting component 456 is located at the high position of the second inner lower protrusion. The limiting member 4561 blocks the bottom of the clamping component 453 to limit the movement of the battery cell 41 after rotation into the casing. Throughout the process, each casing insertion device 45 independently completes the insertion of different battery cells 41, which improves the insertion efficiency and ensures the insertion quality.

[0080] like Figure 2 and Figure 6 As shown, the first rotating component 441 includes: a first rotating shaft 4411, a transmission component 4412, and a driving component 4413. The first rotating shaft 4411 passes through the first upper turntable 442 and the first lower turntable 443. The first rotating shaft 4411 is connected to the first base 451 through two connecting base plates. The driving component 4413 can be a motor or other power mechanism. The transmission component 4412 can be a gear. The transmission component 4412 is connected to one end of the first rotating shaft 4411. The driving component 4413 is connected to the first rotating shaft 4411 through the transmission component 4412.

[0081] When the driving component 4413 rotates, it drives the transmission component 4412 to rotate. Since the transmission component 4412 is connected to one end of the first rotating shaft 4411, the first rotating shaft 4411 begins to rotate, thereby driving the first base 451 connected to the first rotating shaft 4411 to rotate. As a result, the housing device 45 rotates relative to the first upper turntable 442 and the first lower turntable 443. In this embodiment, the first turret device is driven by a motor and gears. Gear drive is more efficient than cylinder and screw drive. The first turret device can install 12 sets of housing devices 45, and each housing device 45 can be interchanged for easy maintenance and debugging.

[0082] Based on the above embodiments, in one embodiment, such as Figure 4 and Figure 5 As shown, the clamping assembly 453 includes: a magnetic clamping member 4531, a gear, a rack 4532, a second cam follower 4533, and a third elastic member 4534.

[0083] In this embodiment, the magnetic clamping member 4531 adopts a U-shaped magnet block and uses a magnetic clamping housing 42. One end of the magnetic clamping member 4531 is provided with a gear, and the rack 4532 meshes with the gear. The rack 4532 is set on the first upper boss through the second cam follower 4533. The second cam follower 4533 is slidable in the vertical direction relative to the first base 451. The second cam follower 4533 is connected to the first base 451 through the third elastic member 4534.

[0084] The third elastic element 4534 can be a spring. The third elastic element 4534 is used to connect the second cam follower 4533 and the first base 451 so that when the second cam follower 4533 moves on the first upper boss, the third elastic element 4534 can provide a certain buffer to the second cam follower 4533 to avoid excessive force.

[0085] When the clamping assembly 453 is clamping only the housing 42, the second cam follower 4533 moves to the high position of the first upper boss, the rack 4532 moves upward, and the gear rotates. At this time, the magnetic clamping member 4531 is upright and is only used to clamp the housing 42.

[0086] After the battery is installed in the casing, the clamping assembly 453 is used to clamp the battery cell 41 after it is installed in the casing. The second cam follower 4533 moves to the low position of the first upper boss, the rack 4532 moves downward, and the gear rotates. At this time, the magnetic clamping member 4531 is inverted and is used to clamp the battery cell 41 after it is installed in the casing.

[0087] Based on the above embodiments, in one embodiment, such as Figure 4 and Figure 5 As shown, the pressing assembly 452 includes: a pressing head 4521, a third cam follower 4522, and a fourth elastic element 4523.

[0088] The top of the pressure head 4521 is connected to the third cam follower 4522. The pressure head 4521 is mounted on the first upper boss via the third cam follower 4522. The third cam follower 4522 is slidable vertically relative to the first base 451. The third cam follower 4522 is connected to the first base 451 via a fourth elastic element 4523. The fourth elastic element 4523 can be a spring. The fourth elastic element 4523 is used to connect the third cam follower 4522 and the first base 451 so that when the third cam follower 4522 moves on the first upper boss, the fourth elastic element 4523 can provide a certain buffer to the third cam follower 4522, avoiding excessive downward pressure from the pressure head 4521 that could damage the housing 42.

[0089] After the battery cell 41 is delivered from the battery cell conveyor line 1, the transfer turntable transports the battery cell 41 to the lifting assembly 454. After the housing 42 is delivered from the second housing conveyor line 3, the transfer turntable transports the housing 42 to the clamping assembly 453. Before the battery cell 41 enters the housing, the third cam follower 4522 is in the high position of the first upper boss. Under the lifting of the third cam follower 4522, the pressure head 4521 moves upward, the clamping assembly 453 is used to clamp the housing 42, and the lifting assembly 454 is in the low position to support the battery cell 41. When the battery cell 41 is inserted into the casing, the third cam follower 4522 is in the low position of the first upper boss, the pressure head 4521 moves downward, and the pressure head 4521 presses down on the casing 42 held by the clamping assembly 453 until the casing 42 is disengaged from the clamping assembly 453. At the same time, the lifting assembly 454 is in the high position to lift the battery cell 41, thereby completing the insertion of the battery cell 41 into the casing. After the insertion is completed, the lifting assembly 454 can lift the inserted battery cell 41 to the clamping assembly 453. The clamping assembly 453 rotates the inserted battery cell 41 by a preset angle to facilitate the transfer of the inserted battery cell 41. In the whole process, each insertion device 45 independently completes the insertion of different battery cells 41 into the casing, which improves the insertion efficiency and ensures the insertion quality.

[0090] Based on the above embodiments, in another embodiment, such as Figure 4 and Figure 5 As shown, the lifting assembly 454 includes: a lifting block 4541, a fourth cam follower 4542, and a fifth elastic element 4543.

[0091] The top of the lifting block 4541 supports the battery cell 41, and the bottom of the lifting block 4541 is mounted on the first lower boss via a fourth cam follower 4542. The fourth cam follower 4542 is slidable vertically relative to the first base 451 and is connected to the first base 451 via a fifth elastic element 4543. The fifth elastic element 4543 can be a spring and is used to connect the fourth cam follower 4542 and the first base 451. When the fourth cam follower 4542 moves on the first lower boss, the fifth elastic element 4543 can provide a certain buffer to the fourth cam follower 4542, preventing excessive lifting force from the lifting block 4541 from damaging the battery cell 41 or the housing 42.

[0092] In one specific embodiment, after the battery cell 41 is delivered from the battery cell conveying line 1, the transfer turntable conveys the battery cell 41 to the lifting assembly 454. After the housing 42 is delivered from the second housing conveying line 3, the transfer turntable conveys the housing 42 to the clamping assembly 453. Before the battery cell 41 enters the housing, the third cam follower 4522 is in the high position of the first upper boss. Under the lifting of the third cam follower 4522, the pressure head 4521 moves upward, and the clamping assembly 453 is used to clamp the housing 42. Meanwhile, the fourth cam follower 4542 is in the low position of the first lower boss, and the lifting block 4541 moves downward. At this time, the lifting block 4541 is only used to support the battery cell 41. When the battery cell 41 is inserted into the casing, the third cam follower 4522 is in the low position of the first upper boss, and the pressure head 4521 moves downward, pressing down on the casing 42 held by the clamping assembly 453 until the casing 42 is disengaged from the clamping assembly 453. At the same time, the fourth cam follower 4542 is in the high position of the first lower boss, and the lifting block 4541 moves upward, lifting the battery cell 41 upward, thus completing the insertion of the battery cell 41 into the casing. After insertion, the lifting block 4541 can lift the inserted battery cell 41 to the clamping assembly 453. The clamping assembly 453 rotates the inserted battery cell 41 by a preset angle to facilitate the transfer of the inserted battery cell 41. Throughout the process, each insertion device 45 independently completes the insertion of different battery cells 41, improving insertion efficiency while ensuring insertion quality.

[0093] Compared to existing technologies, the operation of the housing insertion device 45 using the first upper boss and the first lower boss offers higher precision and a simpler structure compared to cylinder and lead screw transmissions. The limiting component 456, the pressing component 452, the clamping component 453, and the lifting component 454 each employ four different cam followers that move along cam trajectories. These cam trajectories determine the displacement of the battery cell 41 and the housing 42 for each action, significantly improving the accuracy of the housing insertion process.

[0094] like Figure 1 and Figure 7 As shown, the battery cell loading system includes a casing loading device 5, which has a casing scanning station and a casing cleaning station. The casing conveying line includes a first casing conveying line 2 and a second casing conveying line 3. The casing loading device 5 includes a slide rail 51, a slide table 52, and a casing gripper assembly 53. The first end of the casing gripper assembly 53 is connected to the slide table 52, and the second end of the casing gripper assembly 53 is slidably mounted on the slide rail 51. The slide table 52 is used to drive the casing gripper assembly 53 to move, so as to first convey the casings on the first casing conveying line 2 to the casing scanning station, then convey the casings on the casing scanning station to the casing cleaning station, and finally convey the casings on the casing cleaning station to the second casing conveying line 3.

[0095] The housing gripper assembly 53 includes a first sliding plate 531, a second sliding plate 532, a third sliding plate 533, a first gripper 534, a second gripper 535, and a third gripper 536. The first slide plate 531, the second slide plate 532, and the third slide plate 533 are arranged alternately. The first ends of the first slide plate 531, the second slide plate 532, and the third slide plate 533 are all connected to the slide table 52. The second ends of the first slide plate 531, the second slide plate 532, and the third slide plate 533 are all slidably arranged on the slide rail 51 in the horizontal direction. The first gripper 534 is slidably arranged on the first slide plate 531 in the vertical direction. The first gripper 534 is used to transport the shells on the first shell conveying line to the shell scanning station. The second gripper 535 is slidably arranged on the second slide plate 532 in the vertical direction. It is used to transport the shells on the shell scanning station to the shell cleaning station. The third gripper 536 is slidably arranged on the third slide plate 533 in the vertical direction. It is used to transport the shells on the shell cleaning station to the second shell conveying line 3.

[0096] Specifically, after a housing is positioned on the first housing conveyor line 2, the first slide plate 531 moves horizontally towards the first housing conveyor line 2. Once in position, a cylinder drives the first gripper 534 to grab the housing on the first housing conveyor line 2. Then, the first slide plate 531 moves towards the housing scanning station, and the first gripper 534 transfers the housing from the first housing conveyor line 2 to the housing scanning station for scanning. After scanning is completed, the second slide plate 532 controls the second gripper 535 to move horizontally towards the housing scanning station. Once in position, a cylinder drives the second gripper 535 to grab the housing from the housing scanning station. Then, the second slide plate 532 moves towards the housing cleaning station, and the second gripper 535 transfers the housing from the housing scanning station to the housing cleaning station for cleaning. After cleaning, the third slide plate 533 controls the third gripper 536 to move towards the shell cleaning station. After moving into position, the cylinder drives the third gripper 536 to grab the shell on the shell cleaning station. Then the third slide plate 533 moves towards the second shell conveyor line 3, and the third gripper 536 transfers the shell on the shell cleaning station to the second shell conveyor line 3. Thus, the second shell conveyor line 3 can send the shell to the shell entry turret 4.

[0097] In this embodiment, as Figure 8 As shown, a scanning assembly is provided at the shell scanning station. The scanning assembly includes a first support plate 54, a motor, a rotating cup 56, and a scanning unit 57. The first support plate 54 is supported on the shell scanning station by a bracket. The scanning unit 57 is used to scan the shell. The scanning unit 57 is arranged opposite to the rotating cup 56. The motor is connected to the rotating cup 56 for transmission, so that the scanning unit 57 scans the shell while the rotating cup 56 is driven by the motor to rotate the shell.

[0098] Generally, the barcode scanning assembly also includes a first detection sensor 55, and multiple rotating cups 56 and barcode scanning units 57 are provided. Multiple rotating cups 56 and multiple barcode scanning units 57 are arranged one-to-one on the first support plate 54. The first detection sensor 55 is arranged opposite to the multiple rotating cups 56. The first detection sensor 55 is used to determine whether each rotating cup 56 has a housing.

[0099] In this embodiment, two first detection sensors 55 are provided, which are respectively arranged on both sides of the multiple rotating cups 56. One first detection sensor 55 is used to transmit signals, and the other first detection sensor 55 is used to receive signals, thereby determining whether each rotating cup 56 has a shell.

[0100] like Figure 9 As shown, a cleaning assembly is provided at the housing cleaning station. The cleaning assembly includes a second support plate 58, multiple dust collection cups 59, and a second detection sensor 60. Multiple dust collection cups 59 are all mounted on the second support plate 58. Each dust collection cup 59 has a dust collection port and a receiving groove for placing the housing. The dust collection port is connected to the receiving groove. When a housing is placed in the receiving groove, dust and particulate matter on the housing can be effectively cleaned by installing a dust collection device at the dust collection port. The second detection sensor is positioned opposite to the multiple dust collection cups 59. The second detection sensor is used to determine whether a housing is placed in each dust collection cup 59. In this embodiment, two second detection sensors 60 are provided, respectively located on both sides of the multiple dust collection cups 59. One second detection sensor 60 is used to transmit signals, and the other second detection sensor 60 is used to receive signals, thereby determining whether a housing is placed in each dust collection cup 59.
