[0002] In the battery manufacturing process, especially for cylindrical batteries, cylindrical cells need to be placed into a steel casing. The steel casing is generally cylindrical with openings at both ends.

The specific process is as follows: First, the steel casing is moved to a positioning station between the first and second positioning components. Then, the first and second positioning components are controlled to move closer together along a first direction until the steel casing is clamped in that direction. Simultaneously, the first and second positioning components extend into the steel casing from their respective openings at both ends to abut against the two ends of the battery cell inside, thus positioning the battery cell in the center of the casing. Finally, the first and second positioning components move away from each other, releasing the clamp on the steel casing and allowing it to continue flowing downstream. This completes the centering process for the battery cell within the casing, ensuring it is centered and facilitating subsequent processing of the casing, thus improving product quality.

[0054] One embodiment of the present invention provides a centering device for positioning an element housed within a receiving component, such that the element is located in the center of the receiving component. It should be noted that, for ease of description, this document uses a steel shell A as the receiving component and a battery cell as an example. The steel shell A is generally cylindrical and has openings at both ends; the battery cell is placed inside the steel shell A through one of the openings.

[0055] Please see Figure 1 In an embodiment of the present invention, the centering device includes a first positioning mechanism 20 and a second positioning mechanism 30. The first positioning mechanism 20 includes a first support frame 21 and a first positioning component 22, the first positioning component 22 being disposed on the first support frame 21. The second positioning mechanism 30 includes a second support frame 31 and a second positioning component 32, the second positioning component 32 being disposed on the second support frame 31. The second positioning component 32 and the first positioning component 22 are arranged opposite to each other in a first direction X, such that a positioning station a for the steel shell A to pass through is formed between them.

[0056] The first positioning component 22 and the second positioning component 32 are configured to move closer to or further away from each other. During the process of the first positioning component 22 and the second positioning component 32 moving closer to each other, they can jointly clamp the steel shell A located at positioning station a, and respectively abut against both ends of the battery cell inside the steel shell A in the first direction X, thereby achieving the positioning of the battery cell inside the steel shell A, so that the battery cell is located in the middle position of the steel shell A (i.e., the distance from one end of the battery cell to the steel shell A is equal to the distance from the battery cell to the other end of the steel shell A).

[0057] Therefore, after the battery cell is placed inside the steel shell A, a centering device is needed to center the battery cell. The specific process of this centering is as follows: First, the steel shell A is transferred to positioning station a between the first positioning component 22 and the second positioning component 32. Then, the first positioning component 22 and the second positioning component 32 are controlled to move closer to each other along the first direction X until the steel shell A is clamped along the first direction X. At the same time, the first positioning component 22 and the second positioning component 32 extend into the interior of the steel shell A from the openings at both ends of the steel shell A, respectively, to abut against the two ends of the battery cell inside the steel shell A, thereby positioning the battery cell inside the steel shell A so that the battery cell is located in the middle of the steel shell A. Finally, the first positioning component 22 and the second positioning component 32 move away from each other, releasing the clamping of the steel shell A, allowing the steel shell A to continue flowing downstream, thus completing the centering process of the battery cell inside the steel shell A, ensuring that the battery cell is located in the middle of the steel shell A, which is beneficial for subsequent processing of the steel shell A and improves product quality.

[0058] Specifically, in this embodiment, the first positioning component 22 has a first positioning portion 221 on the side facing the second positioning component 32. This first positioning portion 221 has a first positioning surface d1 and a second positioning surface d2. The second positioning component 32 has a second positioning portion 321 on the side facing the first positioning component 22, and this second positioning portion 321 has a third positioning surface d3 and a fourth positioning surface d4. The first positioning surface d1 and the third positioning surface d3 are used to abut against the two ends of the steel shell A in the first direction X, respectively, and the second positioning surface d2 and the fourth positioning surface d4 are used to abut against the two ends of the battery cell inside the steel shell A in the first direction X, respectively. Thus, when alignment is required, the first positioning component 22 and the second positioning component 32 are controlled to move closer to each other along the first direction X until the first positioning surface d1 of the first positioning portion 221 and the third positioning surface d3 of the second positioning portion 321 abut against the two ends of the steel shell A, thereby clamping the steel shell A along the first direction X. At the same time, the second positioning surface d2 of the first positioning part 221 and the fourth positioning surface d4 of the second positioning part 321 abut against the two ends of the battery cell inside the steel shell A, thereby positioning the battery cell relative to the steel shell A, so that the battery cell is located in the middle of the steel shell A.

[0059] It is understandable that the distance by which the second positioning surface d2 protrudes from the first positioning surface d1 is equal to the distance by which the fourth positioning surface d4 protrudes from the third positioning surface d3, so that the distance between the battery cell and both ends of the steel shell A is equal after alignment, that is, the battery cell is located in the middle of the steel shell A.

[0060] Please see Figure 1 and Figure 2As shown in the embodiment of the present invention, the first positioning component 22 includes a first slide block 222 and a first mounting base 223. The first slide block 222 is movably connected to the first support frame 21 along a first direction X. The first mounting base 223 is disposed on the first slide block 222. A first positioning part 221 is disposed on the first mounting base 223, such that the first mounting base 223 and the first positioning part 221 move together with the first slide block 222 along the first direction X, thereby enabling the first positioning part 221 to cooperate with the second positioning part 321 to perform centering processing on the battery cell inside the steel shell A.

[0061] In a specific embodiment, the first support frame 21 is provided with a first slide rail 211 extending longitudinally along the first direction X, and the first slide block 222 is provided with a first slider 2221 that slides in cooperation with the first slide rail 211. In this way, the movement of the first slider 2221 along the first slide rail 211 guides the movement of the first slide block 222 relative to the first support frame 21.

[0062] In a specific embodiment, the position of the first mounting base 223 relative to the first slide 222 in the second direction Y is adjustable, and the second direction Y is perpendicular to the first direction X. Thus, by adjusting the position of the first mounting base 223 relative to the first slide 222 along the second direction Y, the position of the first positioning part 221 relative to the second positioning part 321 in the second direction Y can be adjusted, thereby ensuring that the first positioning part 221 and the second positioning part 321 are aligned in the first direction X.

[0063] Furthermore, the first positioning component 22 also includes an adjustment knob 224, which is rotatably connected to the first slide 222 and threadedly connected to the first mounting base 223. Thus, when the adjustment knob 224 is turned, it can move the first mounting base 223 relative to the first slide 222 along the second direction Y, thereby adjusting the position of the first positioning part 221 relative to the second positioning part 321 in the second direction Y.

[0064] Furthermore, the first positioning component 22 also includes a locking member. A first oblong hole 2231 is provided on the first mounting base 223. The locking member passes through the first oblong hole 2231 and is threadedly connected to the first slide block 222 to lock the first mounting base 223 onto the first slide block 222. Thus, when it is necessary to adjust the position of the first positioning part 221 in the second direction Y, firstly, the locking member is loosened, causing it to release its locking of the first mounting base 223. Then, the adjusting knob 224 is turned, thereby moving the first mounting base 223 relative to the first slide block 222 along the second direction Y, thereby adjusting the position of the first positioning part 221 along the second direction Y. When the position is adjusted to the correct position, the adjusting knob 224 is stopped, and the locking member is tightened, causing the locking member to lock the first mounting base 223 onto the first slide block 222. Optionally, the locking member can be a screw.

[0065] In an embodiment of the present invention, the second positioning component 32 includes a second slide 322 and a second mounting base 323. The second slide 322 is movably connected to the second support frame 31 along a first direction X. The second mounting base 323 is disposed on the second slide 322, and the second positioning part 321 is disposed on the second mounting base 323, so that the second mounting base 323 and the second positioning part 321 can move together with the second slide 322 along the first direction X, thereby enabling the second positioning part 321 to cooperate with the first positioning part 221 to complete the centering process of the battery cell inside the steel shell A.

[0066] In a specific embodiment, the second positioning component 32 further includes a first blocking portion 328 and a first buffer elastic member 327. The second positioning portion 321 is movably connected to the second mounting base 323 along a first direction X, and the first blocking portion 328 is mounted on the second mounting base 323. The first buffer elastic member 327 abuts against both the second positioning portion 321 and the first blocking portion 328, providing a spring force that causes the second positioning portion 321 to have a tendency to move towards the first positioning portion 221. Thus, during the process of the first positioning portion 221 and the second positioning portion 321 jointly clamping the steel shell A, the first buffer elastic member 327 can buffer the impact generated by the first positioning portion 221 and the second positioning portion 321 on the steel shell A, thereby avoiding damage to the steel shell A and the battery cell. Optionally, the first buffer elastic member 327 can be a spring.

[0067] In a specific embodiment, the second positioning component 32 further includes a second blocking portion 324 and a second buffer elastic member 325. The second mounting base 323 is movably connected to the second slide 322 along a first direction X, and the second blocking portion 324 is connected to the second slide 322. The second buffer elastic member 325 abuts against both the second blocking portion 324 and the second mounting base 323, providing a spring force that causes the second mounting base 323 to have a tendency to move towards the first positioning portion 221. Thus, during the process of the first positioning portion 221 and the second positioning portion 321 jointly clamping the steel shell A, the second buffer elastic member 325 can buffer the impact generated by the first positioning portion 221 and the second positioning portion 321 on the steel shell A, thereby avoiding damage to the steel shell A and the battery cell. Optionally, the second buffer elastic member 325 can be a spring.

[0068] Furthermore, the second positioning assembly 32 also includes a guide post 3251, a limiting block 3252, and a limiting screw 326. A guide hole extending through the second blocking portion 324 in the first direction X is provided. The guide post 3251 passes through this guide hole and is movable along it. One end of the guide post 3251 is fixedly connected to the second mounting base 323. The second buffer elastic member 325 is sleeved on the guide post 3251, and its opposite ends abut against the second mounting base 323 and the second blocking portion 324, respectively. The end of the guide post 3251 facing away from the second mounting base 323 is connected to the limiting block 3252. The limiting block 3252 is threadedly connected to the limiting screw 326, which abuts against the side of the second blocking portion 324 facing away from the second buffer elastic member 325. Thus, by using the limiting screw 326 to limit the extreme position of the second mounting base 323 moving toward the first positioning component 22, that is, to limit the extreme position of the second positioning part 321 moving toward the first positioning part 221, the steel shell A is prevented from being clamped too tightly by the first positioning part 221 and the second positioning part 321, which would cause damage to the steel shell A and the battery cell.

[0069] Optionally, the second support frame 31 is provided with a second slide rail extending longitudinally along the first direction X, and the second slide block 322 is provided with a second slider that slides in cooperation with the second slide rail. In this way, the movement of the second slider along the second slide rail guides the movement of the second slide block 322 relative to the second support frame 31 along the first direction X.

[0070] Optionally, the second slide block 322 is provided with a fourth slide rail extending longitudinally along the first direction X, and the second mounting base 323 is provided with a fourth slider that slides in cooperation with the fourth slide rail. In this way, the movement of the fourth slider along the fourth slide rail guides the movement of the second mounting base 323 relative to the second slide block 322 along the first direction X.

[0071] It should be noted that, in one embodiment, the first mounting base 223 is provided with a plurality of first positioning parts 221, which are spaced apart along the second direction Y. The second mounting base 323 is provided with a plurality of second positioning parts 321, which are spaced apart along the second direction Y. Each pair of first positioning parts 221 corresponds one-to-one with a plurality of second positioning parts 321, and the corresponding first positioning part 221 and second positioning part 321 are aligned in the first direction X, forming a positioning station a. Thus, by providing a plurality of first positioning parts 221 and a plurality of second positioning parts 321, multiple positioning stations a are formed, enabling simultaneous centering of the battery cells located in the steel shell A at each positioning station a, which is beneficial for improving production efficiency. Specifically... Figure 2 In the embodiment shown, the first mounting base 223 is provided with two first positioning parts 221, and the second mounting base 323 is provided with two second positioning parts 321, thereby forming two positioning stations a, which enables the centering process of the battery cells of the steel shell A located at the two positioning stations a at the same time.

[0072] Please see Figure 1 , Figure 3 and Figure 4 As shown in the embodiment of the present invention, the centering device further includes a drive mechanism 40, which includes a drive component, a first transmission component 42, and a second transmission component 43. The first transmission component 42 is driveably connected between the drive component and the first positioning component 22, thereby enabling the drive component to drive the first positioning component 22 to move along the first direction X via the first transmission component 42. The second transmission component 43 is driveably connected between the drive component and the second positioning component 32, thereby enabling the drive component to drive the second positioning component 32 to move along the first direction X via the second transmission component 43. Thus, by using a single drive component to drive the first positioning component 22 and the second positioning component 32 to move along the first direction X, the centering process of the battery cell inside the steel shell A can be achieved. This saves power and reduces device cost; moreover, it facilitates the synchronous control of the first positioning component 22 and the second positioning component 32 to move closer or further apart from each other.

[0073] Specifically, in this embodiment, the drive assembly includes a first drive shaft 411, a second drive shaft 412, a transmission structure (not shown), and a rotary drive member (not shown). The first drive shaft 411 is rotatably disposed relative to the first support frame 21, and the second drive shaft 412 is rotatably disposed relative to the second support frame 31. The transmission structure is drively connected between the first drive shaft 411 and the second drive shaft 412, so that the rotation of either the first drive shaft 411 or the second drive shaft 412 can drive the other to rotate. The rotary drive member is drively connected to either the first drive shaft 411 or the second drive shaft 412 to drive the first drive shaft 411 or the second drive shaft 412 to rotate.

[0074] The first transmission assembly 42 is driven between the first drive shaft 411 and the first positioning assembly 22, so that when the first drive shaft 411 rotates, it can drive the first positioning assembly 22 to move along the first direction X. The second transmission assembly 43 is driven between the second drive shaft 412 and the second positioning assembly 32, so that when the second drive shaft 412 rotates, it can drive the second positioning assembly 32 to move along the first direction X. Optionally, the transmission structure can adopt a belt drive structure or a gear drive structure, as long as it can achieve synchronous rotation of the first drive shaft 411 and the second drive shaft 412, which is not limited here.

[0075] Specifically, in the embodiments, the first transmission assembly 42 includes a first swing arm 421, a first cam structure 422, and a first connecting rod structure 423 (see...). Figure 1 The first swing arm 421 has a first end b1 and a second end b2. The first end b1 of the first swing arm 421 is rotatably disposed relative to the first support frame 21, thereby enabling the first swing arm 421 to swing around the first end b1. A first cam structure 422 is driven between the first drive shaft 411 and the first swing arm 421 to convert the rotational motion of the first drive shaft 411 into the swinging motion of the first swing arm 421 around the first end b1. The second end b2 of the first swing arm 421 is driven to a first connecting rod structure 423, which is driven to a first positioning assembly 22 to convert the swinging motion of the first swing arm 421 into the linear movement of the first positioning assembly 22 along the first direction X. Thus, when it is necessary to drive the first positioning assembly 22 to move along the first direction X, the first drive shaft 411 rotates, thereby driving the first swing arm 421 to swing around the first end b1 through the first cam structure 422, and the first swing arm 421 drives the first positioning assembly 22 to move along the first direction X through the first connecting rod structure 423.

[0076] Specifically, in this embodiment, the first cam structure 422 includes a first cam 4221 and a first roller 4222. The first cam 4221 is mounted on the first drive shaft 411 and rotates synchronously with the first drive shaft 411. The first roller 4222 is mounted on the first swing arm 421 and rolls in cooperation with the first cam 4221, so that during rotation, the first cam 4221 drives the first swing arm 421 to swing around the first end b1 via the first roller 4222. Thus, when the first drive shaft 411 rotates, it drives the first cam 4221 to rotate, thereby causing the first roller 4222 to roll along the first cam 4221, which in turn causes the first cam 4221 to drive the first swing arm 421 to swing around the first end b1 via the first roller 4222. It can be understood that the first roller 4222 is located between the first end b1 and the second end b2 of the first swing arm 421, preferably approximately in the middle of the first swing arm 421.

[0077] Furthermore, the first cam structure 422 also includes a first elastic element 4223, one end of which is fixed relative to the first support frame 21, and the other end is connected to the second end b2 of the first rocker arm 421. This provides a preload force that keeps the first roller 4222 pressed against the first cam 4221, ensuring that the first roller 4222 and the first cam 4221 maintain a rolling engagement. Optionally, the first elastic element 4223 can be a spring.

[0078] Specifically, in the embodiment, the first positioning component 22 has a first guide groove 2251 (see... Figure 5 The first guide groove 2251 extends along a third direction Z intersecting the first direction X. Preferably, the third direction Z is perpendicular to the first direction X. Specifically... Figure 1 In the embodiment shown, the first direction X is the left-right direction, the second direction Y is the direction perpendicular to the paper, and the third direction Z is the up-down direction.

[0079] Please see Figure 1 and Figure 5 As shown, the first linkage structure 423 includes a first linkage 4231, a first drive rod 4232, and a second roller 4233. The first linkage 4231 is rotatably mounted relative to the first support frame 21 and has a third end b3 and a fourth end b4. One end of the first drive rod 4232 is hinged to the second end b2 of the first swing arm 421, and the other end of the first drive rod 4232 is hinged to the third end b3 of the first linkage 4231. The second roller 4233 is rotatably connected to the fourth end b4 of the first linkage 4231 and rolls in engagement with the first guide groove 2251. Thus, when the first swing arm 421 swings, the first swing arm 421 drives the first linkage 4231 to rotate via the first drive rod 4232, and the first linkage 4231 drives the second roller 4233 to move along the first guide groove 2251 of the first positioning assembly 22, thereby driving the first positioning assembly 22 to move along the first direction X.

[0080] Furthermore, the first positioning component 22 also includes a first guide seat 225 connected to the first slide 222, and a first guide groove 2251 is formed on the first guide seat 225. Thus, when the first connecting rod 4231 rotates, it drives the first slide 222 to move along the first direction X through the second roller 4233, thereby realizing the movement of the first positioning part 221 along the first direction X.

[0081] Furthermore, the position of the first guide seat 225 on the first slide 222 is adjustable along the first direction X, thereby adjusting the range of movement of the first slide 222 relative to the first support frame 21 along the first direction X, so as to ensure that the first slide 222 can drive the first positioning part 221 to move to contact the steel shell A and the battery cell inside the steel shell A.

[0082] Optionally, the first positioning assembly 22 further includes a first locking screw and a first adjusting screw. The first slide 222 has a second oblong hole extending longitudinally along the first direction X. The first locking screw passes through the second oblong hole and is threadedly connected to the first guide seat 225 to lock the first guide seat 225 onto the first slide 222. The first adjusting screw is rotatably connected to the first slide 222 and threadedly connected to the first guide seat 225. Thus, when the position of the first guide seat 225 needs to be adjusted, firstly, the first locking screw is loosened to release the locking of the first guide seat 225. Then, the first adjusting screw is tightened, thereby moving the first guide seat 225 relative to the first slide 222 along the first direction X until the first guide seat 225 is in place. Finally, the first locking screw is tightened to re-lock the first guide seat 225 onto the first slide 222.

[0083] Furthermore, the centering device also includes a base plate 10, on which the first support frame 21 and the second support frame 31 are both fixedly connected. The first drive shaft 411 and the second drive shaft 412 are both mounted on the base plate 10 via bearings. A rotary drive component is also mounted on the base plate 10 and is drivenly connected to either the first drive shaft 411 or the second drive shaft 412. The end of the first elastic member 4223 located away from the first swing arm 421 is connected to the base plate 10.

[0084] Please continue reading Figures 3 to 4 Furthermore, the first transmission assembly 42 also includes a first support 4212 and a first swing shaft 4211. The first support 4212 is fixedly connected to the base plate 10, and the first swing shaft 4211 is fixedly mounted on the first support 4212. The first end b1 of the first swing arm 421 is mounted on the first swing shaft 4211 through a bearing, so that the first swing arm 421 can swing around the first swing shaft 4211 under the drive of the first cam 4221.

[0085] Please see Figure 1 , Figure 3 and Figure 4As shown, in a specific embodiment, the second transmission assembly 43 includes a second swing arm 431, a second cam structure 432, and a second connecting rod structure 433. The second swing arm 431 has a fifth end b5 and a sixth end b6. The fifth end b5 of the second swing arm 431 is rotatably disposed relative to the second support frame 31, thereby enabling the second swing arm 431 to swing around the fifth end b5. The second cam structure 432 is driven between the second drive shaft 412 and the second swing arm 431 to convert the rotational motion of the second drive shaft 412 into the swinging motion of the second swing arm 431 around the fifth end b5. The sixth end b6 of the second swing arm 431 is driven to the second connecting rod structure 433, and the second connecting rod structure 433 is driven to the second positioning assembly 32 to convert the swinging motion of the second swing arm 431 into the linear movement of the second positioning assembly 32 along the first direction X. Thus, when it is necessary to drive the second positioning component 32 to move along the first direction X, the second drive shaft 412 drives the second swing arm 431 to swing around the fifth end b5 through the second cam structure 432, and the second swing arm 431 drives the second positioning component 32 to move along the first direction X through the second linkage structure 433.

[0086] Specifically, in this embodiment, the second cam structure 432 includes a second cam 4321 and a third roller 4322. The second cam 4321 is mounted on the second drive shaft 412 and rotates synchronously with it. The third roller 4322 is mounted on the second swing arm 431 and rolls in cooperation with the second cam 4321, so that during rotation, the second cam 4321 drives the second swing arm 431 to swing around the fifth end b5 via the third roller 4322. Thus, when the second drive shaft 412 rotates, it drives the second cam 4321 to rotate, thereby causing the third roller 4322 to roll along the second cam 4321, which in turn causes the second cam 4321 to drive the second swing arm 431 to swing around the fifth end b5 via the third roller 4322. It is understood that the third roller 4322 is located between the fifth end b5 and the sixth end b6 of the second swing arm 431, preferably approximately in the middle of the second swing arm 431.

[0087] Furthermore, the second cam structure 432 also includes a second elastic element 4323. One end of the second elastic element 4323 is fixed relative to the second support frame 31, and the other end is connected to the sixth end b6 of the second swing arm 431. This provides a preload force that keeps the third roller 4322 pressed against the second cam 4321, ensuring that the third roller 4322 and the second cam 4321 maintain a rolling engagement. Optionally, the second elastic element 4323 can be a spring. The end of the second elastic element 4323 away from the second swing arm 431 is connected to the base plate 10.

[0088] In a specific embodiment, the second positioning component 32 has a second guide groove (not shown) that extends along a third direction Z intersecting the first direction X. Preferably, the third direction Z is perpendicular to the first direction X.

[0089] Please participate Figure 1 As shown, the second linkage structure 433 includes a second linkage 4331, a second drive rod 4332, and a fourth roller (not shown). The second linkage 4331 is rotatably mounted relative to the second support frame 31 and has a seventh end b7 and an eighth end b8. One end of the second drive rod 4332 is hinged to the sixth end b6 of the second swing arm 431, and the other end of the second drive rod 4332 is hinged to the seventh end b7 of the second linkage 4331. The fourth roller is rotatably connected to the eighth end b8 of the second linkage 4331 and rolls into the second guide groove. Thus, when the second swing arm 431 swings, the second swing arm 431 drives the second linkage 4331 to rotate via the second drive rod 4332, and the second linkage 4331 drives the fourth roller to move along the second guide groove of the second positioning assembly 32, thereby driving the second positioning assembly 32 to move along the first direction X.

[0090] Furthermore, the second positioning component 32 also includes a second guide seat 329 connected to the second slide 322, and a second guide groove is formed on the second guide seat 329. Thus, when the second connecting rod 4331 rotates, it drives the second slide 322 to move along the first direction X through the fourth roller, thereby realizing the movement of the second positioning part 321 along the first direction X.

[0091] Furthermore, the position of the second guide seat 329 on the second slide 322 is adjustable along the first direction X, thereby adjusting the range of movement of the second slide 322 relative to the second support frame 31 along the first direction X, so as to ensure that the second slide 322 can drive the second positioning part 321 to move to contact the steel shell A and the battery cell inside the steel shell A.

[0092] Optionally, the second positioning assembly 32 further includes a second locking screw and a second adjusting screw. The second slide 322 has a third oblong hole extending longitudinally along the first direction X. The second locking screw passes through this third oblong hole and is threadedly connected to the second guide seat 329 to lock the second guide seat 329 onto the second slide 322. The second adjusting screw is rotatably connected to the second slide 322 and threadedly connected to the second guide seat 329. Thus, when the position of the second guide seat 329 needs to be adjusted, firstly, the second locking screw is loosened to release the locking of the second guide seat 329. Then, the second adjusting screw is tightened, thereby moving the second guide seat 329 relative to the second slide 322 along the first direction X until the second guide seat 329 is in place. Finally, the second locking screw is tightened to re-lock the second guide seat 329 onto the second slide 322.

[0093] Please continue reading Figure 3 and Figure 4 Furthermore, the second transmission assembly 43 also includes a second support 4312 and a second swing shaft 4311. The second support 4312 is fixedly connected to the base plate 10, and the second swing shaft 4311 is fixedly connected to the second support 4312. The fifth end b5 of the second swing arm 431 is mounted on the second swing shaft 4311 via a bearing, so that the second swing arm 431 can swing around the second swing shaft 4311 under the drive of the second cam 4321.

[0094] Please see Figure 4 and Figure 6 As shown, in an embodiment of the present invention, the centering device further includes a limiting mechanism, which includes a third support frame 51 and a limiting component 52. The limiting component 52 is movably connected to the third support frame 51 along the third direction Z, and has a limiting part 521 located on the side of the positioning station a in the third direction Z, so that during the movement of the limiting component 52 along the third direction Z, the limiting part 521 can move closer to or further away from the steel shell A located at the positioning station a.

[0095] The limiting component 52 can be moved to a limited position along the third direction Z so that the limiting part 521 limits the steel shell A located at the positioning station a in the third direction Z to prevent the steel shell A from jumping in the third direction Z, and ensure that the first positioning component 22 and the second positioning component 32 can successfully complete the centering process.

[0096] It should be noted that when the limiting component 52 moves to the limited position (that is, when the limiting part 521 limits the steel shell A), the limiting part 521 just makes contact with the steel shell A located at the positioning station a or there is a small gap. As long as it can play the role of limiting the steel shell A in the third direction Z, it is not limited here.

[0097] It should also be noted that when the steel shell A is conveyed by the conveyor line through the positioning station a, the limiting part 521 of the limiting component 52 limits the steel shell A in the third direction Z. That is, the steel shell A located at the positioning station a is limited between the limiting part 521 and the conveyor line to prevent the steel shell A from jumping along the third direction Z on the conveyor line.

[0098] In a specific embodiment, the limiting component 52 includes a third slide 522, which is movably connected to the third support frame 51 along the third direction Z. The limiting part 521 is connected to the side of the third slide 522 facing the positioning station a, so that the third slide 522 can drive the limiting part 521 to move closer to or away from the steel shell A located at the positioning station a along the third direction Z.

[0099] Optionally, the third support frame 51 is provided with a third slide rail 511 extending longitudinally along the third direction Z, and the third slide block 522 is provided with a third slider 5221 that slides in cooperation with the third slide rail 511. Thus, the movement of the third slide block 522 relative to the third support frame 51 is guided by the movement of the third slider 5221 along the third slide rail 511.

[0100] In some embodiments, the drive mechanism 40 further includes a third transmission component 44, which is tractively connected between the drive component and the limiting component 52. This allows the drive component to drive the limiting component 52 to move along a third direction Z via the third transmission component 44, thereby limiting the steel shell A. Thus, by using a single drive component to drive the limiting component 52 to move along a third direction Z, the first positioning component 22 to move along a first direction X, and the second positioning component 32 to move along the first direction X, the limiting of the steel shell A and the centering of the battery cells within the steel shell A are achieved. This saves power and reduces device cost; furthermore, it facilitates control over the sequence of movement of the limiting component 52, the first positioning component 22, and the second positioning component 32.

[0101] Specifically, in this embodiment, the third transmission assembly 44 includes a third swing arm 441, a third cam structure, and a third connecting rod structure 443. The third swing arm 441 has a ninth end b9 and a tenth end b10. The ninth end b9 of the third swing arm 441 is rotatably disposed relative to the third support frame 51, thereby enabling the third swing arm 441 to swing around the ninth end b9. The third cam structure is driven between the third swing arm 441 and the first drive shaft 411 or the second drive shaft 412 to convert the rotational motion of the first drive shaft 411 or the second drive shaft 412 into the swinging motion of the third swing arm 441 around the ninth end b9. The tenth end b10 of the third swing arm 441 is driven to the third connecting rod structure 443, and the third connecting rod structure 443 is driven to the limiting assembly 52 to convert the swinging motion of the third swing arm 441 into the linear movement of the limiting assembly 52 along the third direction Z. Thus, when it is necessary to drive the limiting component 52 to move along the third direction Z, the first drive shaft 411 or the second drive shaft 412 drives the third swing arm 441 to swing around the ninth end b9 through the third cam structure, and the third swing arm 441 drives the limiting component 52 to move along the third direction Z through the third link structure 443.

[0102] Specifically, in this embodiment, the third cam structure includes a third cam 4421 and a fifth roller (not shown). The third cam 4421 is mounted on a first drive shaft 411 or a second drive shaft 412 (specifically...). Figure 4In the illustrated embodiment, the third cam 4421 is mounted on the second drive shaft 412 and rotates synchronously with either the first drive shaft 411 or the second drive shaft 412. A fifth roller is mounted on the third swing arm 441 and rolls in cooperation with the third cam 4421, so that during rotation, the third cam 4421 drives the third swing arm 441 to swing around the ninth end b9 via the fifth roller. Thus, when the first drive shaft 411 or the second drive shaft 412 rotates, it drives the third cam 4421 to rotate, causing the fifth roller to roll along the third cam 4421, thereby causing the third cam 4421 to drive the third swing arm 441 to swing around the ninth end b9 via the fifth roller. It is understood that the fifth roller is located between the ninth end b9 and the tenth end b10 of the third swing arm 441, preferably approximately in the middle of the third swing arm 441.

[0103] Furthermore, the third cam structure also includes a third elastic element 4423. One end of the third elastic element 4423 is fixed relative to the third support frame 51, and the other end is connected to the tenth end b10 of the third swing arm 441. This provides a preload force that keeps the fifth roller pressed against the third cam 4421, ensuring that the fifth roller and the third cam 4421 maintain a rolling engagement. Optionally, the third elastic element 4423 can be a spring. The end of the third elastic element 4423 away from the third swing arm 441 is connected to the base plate 10.

[0104] Specifically, in this embodiment, the limiting component 52 has a third guide groove 5231 extending along a first direction X. The third link structure 443 includes a third link 4431, a third drive rod 4432, and a sixth roller 4433. The third link 4431 is rotatably disposed relative to the third support frame 51 and has an eleventh end b11 and a twelfth end b12. One end of the third drive rod 4432 is hinged to the tenth end b10 of the third swing arm 441, and the other end of the second drive rod 4332 is hinged to the eleventh end b11 of the third link 4431. The sixth roller 4433 is rotatably connected to the twelfth end b12 of the third link 4431 and rolls with the third guide groove 5231. Thus, when the third swing arm 441 swings, the third swing arm 441 drives the third connecting rod 4431 to rotate via the third drive rod 4432. The third connecting rod 4431 drives the sixth roller 4433 to move along the third guide groove 5231 of the limiting component 52, thereby driving the limiting component 52 to move along the third direction Z.

[0105] Furthermore, the limiting assembly 52 also includes a third guide seat 523 connected to the third slide 522, and a third guide groove 5231 is formed on the third guide seat 523. Thus, when the third link 4431 rotates, it drives the third slide 522 to move along the third direction Z through the sixth roller 4433, thereby realizing the movement of the limiting part 521 along the third direction Z.

[0106] Furthermore, the ninth end b9 of the third swing arm 441 is mounted on the first swing shaft 4211 or the second swing shaft 4311 via a bearing, so that the third swing arm 441 can swing around the first swing shaft 4211 or the second swing shaft 4311 under the drive of the third cam 4421. Of course, in other embodiments, the third swing arm 441 may not share the first swing shaft 4211 or the second swing shaft 4311 with the first swing arm 421 or the second swing arm 431. Alternatively, the third swing shaft may be provided on the base plate 10, and the ninth end b9 of the third swing arm 441 may be mounted on the third swing shaft via a bearing. This is not limited here.

[0107] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0108] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
