DETAILED DESCRIPTION

[0073] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0074] In this disclosure, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on the specific circumstances.

[0075] In addition, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may or may not be the same in type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0076] The technical solution of the present disclosure will be further described below with reference to specific embodiments and drawings.

[0077] Please refer to Figures 1, 2 and 3 together. The embodiment of the present disclosure discloses a jig 1, which includes a base 11, a supporting mechanism 12, two clamping mechanisms 13 and a flipping mechanism 14. The supporting mechanism 12 is arranged on the base 11 and is used to fix the top cover 22. The two clamping mechanisms 13 are located on both sides of the supporting mechanism 12 in a first direction (as shown by X in Figure 1), and the clamping mechanisms 13 are used to clamp the battery cells 21. The flipping mechanism 14 is arranged on the base 11 and can drive the two clamping mechanisms 13 to flip between the first position and the second position. The rotation axis of the clamping mechanism 13 is parallel to the second direction (as shown by Y in Figure 1), and the second direction is perpendicular to the first direction.

[0078] When the two clamping mechanisms 13 are both in the first position, the top surfaces 211 of the two battery cells 21 are opposite to each other, and the top cover 22 is located between the top surfaces 211 of the two battery cells 21. When the flipping mechanism 14 drives the two clamping mechanisms 13 to flip from the first position to the second position, the side surfaces of the two battery cells 21 are attached to form a battery cell group 23, and the top surfaces 211 of the two battery cells 21 face the same direction and are opposite to the top cover 22.

[0079] The supporting mechanism 12 can be located roughly in the middle of the base 11, and the two clamping mechanisms 13 are located on both sides of the supporting mechanism 12, and the distance between the two clamping mechanisms 13 and the supporting mechanism 12 is roughly the same, so as to avoid the situation where the center of gravity of the jig 1 is greatly offset compared to the center of the jig 1 during the process of flipping the two clamping mechanisms 13 by the flipping mechanism 14, so as to ensure the stability of the jig 1.

[0080] When both clamping mechanisms 13 are in the first position, the top surfaces 211 of the two battery cells 21 face each other, and the top cover 22 is located between the top surfaces 211 of the two battery cells 21. Furthermore, because the top cover 22 is fixed to the support mechanism 12 and the two battery cells 21 are clamped by the two clamping mechanisms 13, the relative positions of the two battery cells 21 and the top cover 22 are relatively stable. At this point, the adapter welding process can proceed.

[0081] The adapter plate welding process in this embodiment refers to welding the adapter plate to the tab connected to the battery cell 21 and welding the adapter plate to the top cover 22. The adapter plate serves to connect the top cover 22 and the battery cell 21 and also serves to conduct electricity between the top cover 22 and the battery cell 21 to achieve current conduction.

[0082] After the adapter welding process is completed, the core joining process can be performed. The core joining process in this embodiment refers to the side surfaces of the two battery cells 21 being aligned, and the top surfaces 211 of the two battery cells 21 facing the same direction, so that the two battery cells 21 can be combined together to form a battery module.

[0083] Specifically, the flipping mechanism 14 drives the two clamping mechanisms 13 to flip from the first position to the second position, thereby driving the two battery cells 21 to flip synchronously. When the two clamping mechanisms 13 flip to the second position, the side surfaces of the two battery cells 21 are in contact, and the top surfaces 211 of the two battery cells 21 face the same direction and both face the top cover 22, so that the two battery cells 21 are combined to form a battery cell group 23. In this embodiment, since the top surfaces 211 of the two battery cells 21 are opposite to each other when the two clamping mechanisms 13 are in the first position, the flipping directions of the two clamping mechanisms 13 are opposite during the process of flipping from the first position to the second position, that is, one clamping mechanism 13 flips clockwise and the other clamping mechanism 13 flips counterclockwise, so that after the two clamping mechanisms 13 flip to the second position, the top surfaces 211 of the two battery cells 21 face the same direction.

[0084] Furthermore, in this embodiment, the angle at which the clamping mechanism 13 is flipped from the first position to the second position may be 90°, but it may also be other angles, which are not limited here.

[0085] In the existing technology, the adapter welding process is completed by the adapter welding jig, and the core assembling process is completed by the core assembling jig. After the adapter welding jig completes the adapter welding process, the battery cell 21 and the top cover 22 need to be moved to the core assembling jig before the core assembling process is performed.

[0086] In summary, the jig 1 provided in this embodiment allows the core assembly process to be performed immediately after the adapter welding process. Compared to the prior art, this eliminates the need for handling steps, thereby shortening the battery production cycle. Furthermore, performing both the adapter welding and core assembly processes on a single jig 1 improves the consistency of the jig 1 while maintaining its functional stability.

[0087] Referring to Figure 4 , in some embodiments, the clamping mechanism 13 includes a support base 131 and a clamping assembly 132. The support base 131 is rotatably mounted on the base 11 and is connected to the flip mechanism 14. The flip mechanism 14 is capable of rotating the support base 131 between a first position and a second position. The clamping assembly 132 is mounted on the support base 131 and is capable of clamping the battery cell 21 in the second direction.

[0088] In this embodiment, the battery cell 21 may include two side surfaces facing opposite directions and both facing the second direction.

[0089] The clamping assembly 132 clamps onto two opposite side surfaces, both facing the second direction, thereby clamping the battery cells 21 in the second direction. When the flip mechanism 14 flips the support base 131 to the second position, the two battery cells 21 adhere to each other to form a battery cell group 23. By clamping the battery cells 21 in the second direction, the clamping assembly 132 prevents them from obstructing the battery cells 21, thereby preventing any impact on the adapter welding and core assembly processes.

[0090] In addition, in this embodiment, the clamping assembly 132 can be clamped to the portion of the battery cell 21 close to the bottom surface 212 , and can also be clamped to other portions of the battery cell 21 , which is not limited herein.

[0091] In some other embodiments, the clamping assembly 132 may be directly connected to the flipping mechanism 14 .

[0092] Continuing with FIG4 , in some embodiments, the clamping assembly 132 includes a first cell clamp 1321, a second cell clamp 1322, and a first restoring member 1323. The first cell clamp 1321 is disposed on the support base 131, and the second cell clamp 1322 is disposed on the support base 131 and spaced apart from the first cell clamp 1321 in the second direction. The first restoring member 1323 is connected to the first cell clamp 1321 and the second cell clamp 1322 to apply a force to move the first cell clamp 1321 and / or the second cell clamp 1322 closer to each other.

[0093] The first battery clamp 1321 can abut the first side surface, and the second battery clamp 1322 can abut the second side surface. The first reset member 1323 can be an elastic member such as a spring, or other components capable of exerting a force, which is not limited here.

[0094] In this embodiment, there are three implementations for the first restoring member 1323 to apply a force to the first battery cell clamp 1321 and / or the second battery cell clamp 1322 to move them closer to each other, which will be described in detail below.

[0095] In the first embodiment, the first battery cell clamp 1321 and the second battery cell clamp 1322 are both slidably disposed on the supporting seat 131, and the first restoring member 1323 applies a force to the first battery cell clamp 1321 toward the second battery cell clamp 1322, and at the same time applies a force to the second battery cell clamp 1322 toward the first battery cell clamp 1321, so that the first battery cell clamp 1321 and the second battery cell clamp 1322 can approach each other and clamp the battery cell 21.

[0096] In the second embodiment, the first battery cell clamp 1321 is slidably set on the supporting seat 131, and the second battery cell clamp 1322 is fixedly set on the supporting seat 131, and the first reset member 1323 applies a force to the first battery cell clamp 1321 toward the second battery cell clamp 1322, so that the first battery cell clamp 1321 can approach the second battery cell clamp 1322 and clamp the battery cell 21.

[0097] In the third embodiment, the first battery cell clamp 1321 is fixedly arranged on the supporting seat 131, and the second battery cell clamp 1322 is slidably arranged on the supporting seat 131, and the first reset member 1323 applies a force to the second battery cell clamp 1322 toward the first battery cell clamp 1321, so that the second battery cell clamp 1322 can approach the first battery cell clamp 1321 and clamp the battery cell 21.

[0098] The first restoring member 1323 brings the first cell clamp 1321 and the second cell clamp 1322 closer to each other to clamp the cell 21 , thereby preventing the cell 21 from moving or falling off during the adapter welding process and the cell assembly process, thereby ensuring the stability and safety of the cell 21 .

[0099] In some other embodiments, the first restoring member 1323 may be connected to the first battery cell clamp 1321 , the second battery cell clamp 1322 and the supporting base 131 .

[0100] Please continue to refer to Figure 4. In some more specific embodiments, the clamping assembly 132 also includes a cell block 1324. The cell block 1324 is disposed on the supporting base 131 and is used to abut the bottom surface 212 of the cell 21 to limit the movement of the cell 21 away from the top cover 22.

[0101] Please refer to FIG. 3 and FIG. 4 . In this embodiment, the battery cell 21 has a top surface 211 and a bottom surface 212 opposite to each other, wherein the top surface 211 is closer to the top cover 22 than the bottom surface 212 .

[0102] The battery cell block 1324 can ensure that the distance between the battery cell 21 and the top cover 22 is roughly stable, that is, it can prevent the distance between the battery cell 21 and the top cover 22 from being too large or too small. At the same time, the battery cell block 1324 cooperates with the first battery cell clamp 1321 and the second battery cell clamp 1322 to limit the freedom of the battery cell 21 in space, so that the battery cell 21 can move synchronously with the clamping assembly 132 without moving, offset or falling off.

[0103] In some other more specific implementations, the cell block 1324 may also be provided on the first cell clamp 1321 and the second cell clamp 1322 .

[0104] Referring to Figures 2, 5, and 6, in some embodiments, the flipping mechanism 14 includes a first driving member (not shown), a transmission assembly 142, and a first rotating shaft 143. The transmission assembly 142 is connected to the first driving member. The first rotating shaft 143 is rotatably mounted on the base 11 and connects the transmission assembly 142 to the clamping mechanism 13. The rotation axis of the first rotating shaft 143 is parallel to the second direction. The first driving member drives the first rotating shaft 143 to rotate via the transmission assembly 142, thereby causing the clamping mechanism 13 to flip between the first position and the second position.

[0105] The first driving member serves as a power source of the flip mechanism 14 , providing power for the rotation of the first rotating shaft 143 .

[0106] One end of the first rotating shaft 143 is connected to the driving assembly, and the other end is connected to the clamping mechanism 13. The first driving member drives the transmission assembly 142 to drive the first rotating shaft 143 to rotate around the rotation axis of the first rotating shaft 143, thereby driving the clamping mechanism 13 to flip synchronously.

[0107] The first rotating shaft 143 drives the clamping mechanism 13 to flip between the first position and the second position, thereby improving the stability of the clamping mechanism 13 during the flipping process.

[0108] In some other embodiments, the first rotating shaft 143 may also be connected to the first driving member, so that the first driving member can directly drive the first rotating shaft 143 to rotate.

[0109] Referring to Figure 5 , in some more specific embodiments, the transmission assembly 142 includes a gear 1421, a rack 1422, and a stopper assembly 1423. The gear 1421 is sleeved onto the first rotating shaft 143. The rack 1422 is slidably mounted on the base 11 and connected to the first driving member. The rack 1422 meshes with the gear 1421. When the rack 1422 moves, it drives the gear 1421 to rotate, thereby driving the first rotating shaft 143 to rotate synchronously. The stopper assembly 1423 is used to limit the travel distance of the rack 1422.

[0110] The first rotating shaft 143 and the gear 1421 rotate synchronously.

[0111] It is understood that, because the meshing relationship between gear 1421 and rack 1422 enables a precise transmission ratio, when the first driving member drives the first rotating shaft 143 to rotate via gear 1421 and rack 1422, the rotation angle of the first rotating shaft 143 can be made more precise. At the same time, due to the high transmission efficiency of gear 1421 and rack 1422, the first driving member can quickly and relatively completely transmit power to the first rotating shaft 143 via gear 1421 and rack 1422, thereby improving the utilization rate of the power output by the first driving member. Furthermore, the transmission stability of gear 1421 and rack 1422 is high. Therefore, when the first driving member drives the first rotating shaft 143 to rotate via gear 1421 and rack 1422, the first rotating shaft 143 can be prevented from deflecting or vibrating, thereby ensuring the stability and accuracy of the rotation of the first rotating shaft 143.

[0112] In addition, the limit assembly 1423 can limit the rotation angle of the gear 1421 by limiting the moving distance of the rack 1422, thereby limiting the rotation angle of the first rotating shaft 143, so that the first rotating shaft 143 can drive the clamping mechanism 13 to accurately flip from the first position to the second position, or accurately flip from the second position to the first position.

[0113] In some other more specific embodiments, the limiting member may also directly limit the rotation angle of the gear 1421 .

[0114] Continuing with FIG5 , in some embodiments, the limiting assembly 1423 includes a first limiting member 1423a, a second limiting member 1423b, and a limiting block 1423c. The second limiting member 1423b is spaced apart from the first limiting member 1423a in the direction of movement of the rack 1422. The limiting block 1423c is connected to the rack 1422 and is located between the first limiting member 1423a and the second limiting member 1423b.

[0115] Exemplarily, when the clamping mechanism 13 is in the first position, the limiting block 1423c abuts against the first limiting member 1423a.

[0116] The first driving member drives the rack 1422 to move and drives the gear 1421 to rotate, so that the first rotating shaft 143 and the gear 1421 rotate synchronously, thereby driving the clamping mechanism 13 to flip from the first position to the second position. During this process, the limit block 1423c moves away from the first limit member 1423a and approaches the second limit member 1423b.

[0117] When the limiting block 1423 c abuts against the second limiting member 1423 b , the first driving member stops driving the rack 1422 . At this time, the clamping mechanism 13 just flips to the second position, so that the two battery cells 21 are combined to form a battery cell group 23 .

[0118] After the two battery cells 21 are combined to form the battery cell group 23, the first driving member drives the rack 1422 to move in the opposite direction, thereby driving the gear 1421 to rotate in the opposite direction. This causes the first rotating shaft 143 and the gear 1421 to rotate in the opposite direction synchronously, thereby driving the clamping mechanism 13 to flip from the second position back to the first position, thereby achieving reset. During this process, the limit block 1423c moves away from the second limit member 1423b and approaches the first limit member 1423a.

[0119] When the limiting block 1423c abuts against the first limiting member 1423a, the first driving member stops driving the rack 1422. At this time, the clamping mechanism 13 just flips to the first position, thereby achieving reset.

[0120] By limiting the movement distance of the limit block 1423 c by the first limit member 1423 a and the second limit member 1423 b , the movement distance of the rack 1422 can be limited, ensuring that the rack 1422 does not exceed a predetermined range during movement, thereby limiting the rotation angle of the gear 1421 .

[0121] In some other embodiments, the limiting block 1423 c may be connected to the gear 1421 .

[0122] Referring to FIG. 5 , in some embodiments, the transmission assembly 142 further includes a first guide rail 1424, a push plate 1425, and a clamp 1426. The first guide rail 1424 is disposed on the base 11 and extends along the direction of movement of the rack 1422. The push plate 1425 is slidably connected to the first guide rail 1424 and connected to the rack 1422. The push plate 1425 is also connected to the first driving member. The clamp 1426 is disposed on the base 11 and is used to limit the movement of the push plate 1425 when the clamping mechanism 13 is in the first position.

[0123] Rack 1422 is connected to push plate 1425, which is in turn connected to the first driver. This allows the first driver to drive push plate 1425, driving rack 1422 to move. Push plate 1425 is also slidably connected to first guide rail 1424, allowing it to move along the direction of first guide rail 1424. This, in turn, allows rack 1422 to move along the direction of first guide rail 1424, thereby preventing the paper strip from shifting during movement. It should be noted that the direction of extension of first guide rail 1424 is a straight line.

[0124] Among them, when the clamping mechanism 13 is in the first position to perform the adapter plate welding process, the clamp 1426 limits the movement of the push plate 1425 to prevent the rack 1422 from moving, thereby preventing the gear 1421 from rotating, and preventing the clamping mechanism 13 from flipping back from the first position, thereby avoiding affecting the adapter plate welding process.

[0125] In some other embodiments, the rack 1422 may be slidably connected to the first guide rail 1424 , the first driving member is connected to the rack 1422 , and the clamp 1426 is used to limit the movement of the rack 1422 when the clamping mechanism 13 is in the first position.

[0126] In some more specific embodiments, the clamp 1426 is a pneumatic clamp.

[0127] The working principle of the pneumatic clamp is to use air pressure to control the opening and closing of the clamp.

[0128] For example, when the clamping mechanism 13 is in the first position to perform the adapter welding process, the pneumatic clamp evacuates air to control the formation of negative pressure between the push plate 1425 and the first guide rail 1424, thereby restricting the movement of the push plate 1425. After the adapter welding process is completed, the pneumatic clamp vents air to control the formation of normal pressure between the push plate 1425 and the first guide rail 1424, thereby restricting the contact of the push plate 1425.

[0129] In some other more specific implementations, the clamp 1426 may also be an electric clamp 1426 .

[0130] Please refer to Figures 6 and 7 together. In some more specific embodiments, the flip mechanism 14 also includes a second rotating shaft 144, which is rotatably disposed on the base 11 and is coaxial with the first rotating shaft 143. The first rotating shaft 143 and the second rotating shaft 144 are connected to both sides of the clamping mechanism 13.

[0131] The second rotating shaft 144 is coaxial with the first rotating shaft 143 . When the first rotating shaft 143 drives the clamping mechanism 13 to flip, the second rotating shaft 144 rotates along with the clamping mechanism 13 .

[0132] The first rotating shaft 143 and the second rotating shaft 144 are connected to both sides of the clamping mechanism 13, so that the weight of the clamping mechanism 13 is evenly divided by the first rotating shaft 143 and the second rotating shaft 144, thereby preventing the weight of the clamping mechanism 13 from being entirely borne by the first rotating shaft 143, avoiding the first rotating shaft 143 from breaking, and extending the service life of the first rotating shaft 143.

[0133] In some other more specific embodiments, both ends of the first rotating shaft 143 are rotatably disposed on the base 11 , and the clamping mechanism 13 is connected to the middle position of the first rotating shaft 143 .

[0134] Please refer to FIG. 8 . In some embodiments, the fixture 1 further includes a clamping mechanism 15 . The clamping mechanism 15 is disposed on the base 11 and is used to clamp the portion of the battery cell group 23 close to the top cover 22 .

[0135] It is understandable that although the core-closing process fits the sides of the two battery cells 21 together to form a battery module, there is no connection between the two battery cells 21 at this time. Therefore, if the clamping mechanism 13 is reset, the two battery cells 21 will move freely and destroy the relative position between the two battery cells 21, thereby separating the battery module into two free battery cells 21 again. In order to solve this problem, in this embodiment, after completing the core-closing process, the bundling glue process can be performed immediately. Among them, the bundling glue process refers to the process of applying bundling glue between the two battery cells 21. The bundling glue can connect the two battery cells 21 together, thereby fixing the relative position between the two battery cells 21, so that the two battery cells 21 are combined to form a stable battery cell group 23.

[0136] Specifically, when the clamping mechanism 13 flips to the second position, the clamping mechanism 15 clamps the cell group 23, thereby maintaining the relative position between the two cell groups 21. At this point, the flipping mechanism 14 can drive the clamping mechanism 13 to flip from the second position to the first position, completing the reset. The external device then completes the adhesive bonding process.

[0137] Illustratively, the clamping mechanism 15 can clamp the battery cell group 23 along the second direction, and when the clamping mechanism 13 clamps the battery cell 21 away from the top surface 211, the clamping mechanism 15 can clamp the portion of the battery cell group 23 close to the top cover 22, thereby avoiding interference between the clamping mechanism 15 and the clamping mechanism 13.

[0138] In summary, the jig 1 provided in this embodiment can proceed to the gluing and binding process after completing the adapter plate welding and core assembly processes. Compared to the existing technology, this eliminates the need for handling steps, thereby further shortening the battery production cycle. Furthermore, performing the adapter plate welding, core assembly, and gluing processes on a single jig 1 improves the consistency of the jig 1 while maintaining its functional stability.

[0139] After the adhesive application and bundling process is complete, an external device can also complete the Mylar wrapping and casing insertion process. The Mylar wrapping and casing insertion process includes the Mylar wrapping process and the casing insertion process. The Mylar wrapping process involves wrapping the Mylar film around the surface of the battery cell assembly 23. The casing insertion process involves inserting the Mylar-wrapped battery cell assembly 23 into the battery casing. The Mylar film prevents the battery cell assembly 23 from being scratched by the battery casing during the casing insertion process. The Mylar film also acts as an insulator, preventing direct contact between the battery cells 21 and the battery casing.

[0140] Please continue to refer to Figure 8. In some more specific embodiments, the clamping mechanism 15 includes two clamping sub-mechanisms 151, and the two clamping sub-mechanisms 151 are respectively located on both sides of the supporting mechanism 12 in the second direction. Please refer to Figures 8 and 9 together. The clamping sub-mechanism 151 includes a slide 1511, a second reset member 1512, a clamping assembly 1513, and a self-locking assembly 1514. The slide 1511 is slidably disposed on the base 11. The second reset member 1512 is connected to the slide 1511 and the base 11, and applies a force to the slide 1511 along the second direction toward the supporting mechanism 12. The clamping assembly 1513 is disposed on the slide 1511 and is used to clamp the portion of the battery cell group 23 close to the top cover 22. The self-locking component 1514 can switch between a locked state and an unlocked state. When the self-locking component 1514 is in the locked state, the self-locking component 1514 locks the slide 1511 at a position where there is a gap with the battery pack 23. When the self-locking component 1514 switches to the unlocked state, the self-locking component 1514 unlocks the slide 1511.

[0141] In this embodiment, the two clamping sub-mechanisms 151 are respectively arranged on both sides of the supporting mechanism 12 along the second direction. After the core closing process is completed, the two clamping sub-mechanisms 151 clamp the battery cell group 23 along the second direction, so that the flipping mechanism 14 can drive the clamping mechanism 13 to flip from the second position to the first position to achieve reset.

[0142] During the process of performing the adapter plate welding process and the core closing process, the self-locking component 1514 is in a locked state. At this time, the self-locking component 1514 overcomes the force applied by the second reset member 1512 to the slide 1511 along the second direction toward the supporting mechanism 12, and locks the slide 1511 at a position with a gap with the battery cell group 23, thereby avoiding interference with the battery cell 21 during the process of the clamping component 1513 driving the battery cell 21 to flip, thereby affecting the flipping and combination of the battery cell 21 to form the battery cell group 23.

[0143] After the core assembly process is completed and before the gluing process is performed, the self-locking assembly 1514 is in the unlocked state. At this time, the self-locking assembly 1514 unlocks the slide 1511, and the force applied by the second restoring member 1512 in the second direction toward the support mechanism 12 drives the slide 1511 toward the support mechanism 12, causing the clamping assembly 1513 to clamp the portion of the cell assembly 23 near the top cover 22.

[0144] In some other more specific embodiments, only the slide 1511, the second reset member 1512 and the clamping assembly 1513 are provided, and after the core closing process is completed and before the gluing process is performed, the second reset member 1512 applies a force along the second direction toward the supporting mechanism 12 to the clamping assembly 1513.

[0145] Continuing with Figures 8 and 9 , in some embodiments, the self-locking assembly 1514 includes a pusher 1514a and a connecting rod 1514b. The pusher 1514a is slidably mounted on the slide 1511. One end of the connecting rod 1514b is pivotally connected to the slide 1511, and the other end is pivotally connected to the pusher 1514a. When the pusher 1514a approaches the slide 1511, the pusher 1514a pushes the connecting rod 1514b to rotate until the extending direction of the connecting rod 1514b is parallel to the second direction, thereby locking the slide 1511 in a position with clearance from the battery cell assembly 23.

[0146] The moving direction of the connecting rod 1514b may be parallel to the first direction.

[0147] In this embodiment, when the pusher 1514a slides from a position away from the slide 1511 to a position close to the slide 1511, the pusher 1514a pushes the connecting rod 1514b to rotate until the extension direction of the connecting rod 1514b is the same as the direction of the force applied by the second reset member 1512 to the slide 1511. That is, the extension direction of the connecting rod 1514b is parallel to the second direction, indicating that the self-locking assembly 1514 is in the locked state. At this point, the connecting rod 1514b can overcome the force applied by the second reset member 1512 to the slide 1511, so that the slide 1511 is self-locked at a position with a gap between it and the battery cell group 23.

[0148] When the pusher 1514a slides from a position close to the slide 1511 to a position away from the slide 1511, the pusher 1514a pushes the connecting rod 1514b to rotate in the opposite direction, so that an angle is formed between the extension direction of the connecting rod 1514b and the direction of the force applied by the second reset member 1512 to the slide 1511, thereby unlocking the slide 1511. That is, the self-locking assembly 1514 is in the unlocked state. The force applied by the second reset member 1512 to the slide 1511 can drive the slide 1511 closer to the support mechanism 12, thereby allowing the clamping assembly 1513 to clamp the battery cell pack 23.

[0149] In some other embodiments, a stopper may also be provided on the base 11 , and the stopper is used to overcome the force applied by the second restoring member 1512 to the slide 1511 , so that the slide 1511 is self-locked at a position with a gap between it and the battery cell group 23 .

[0150] Please continue to refer to Figures 8 and 9. In some embodiments, the clamping assembly 1513 is slidably disposed on the slide 1511 and can move between the storage position and the use position along a third direction (as shown by Z in Figure 10). The storage position is closer to the base 11 than the use position, and the storage position is closer to the base 11 than the battery cell 21, wherein the third direction is perpendicular to the first direction and perpendicular to the second direction.

[0151] It can be understood that since the top cover 22 is fixed to the supporting mechanism 12, there is a certain distance between the top cover 22 and the base 11 in the third direction, and the battery cell group 23 is located on the side of the top cover 22 away from the base 11 in the third direction. Therefore, the position of the clamping assembly 1513 clamping the battery cell group 23 is far away from the base 11 in the third direction, thereby increasing the size of the jig 1 in the third direction.

[0152] In order to solve this problem, in this embodiment, the clamping assembly 1513 can be slidably disposed on the slide 1511 along the third direction and can be switched between the storage position and the use position.

[0153] Specifically, when the jig 1 is not in use, the clamping assembly 1513 is in the storage position, that is, the clamping assembly 1513 is in the position closest to the base 11, which reduces the size of the jig 1 in the third direction and facilitates storage.

[0154] When the self-locking assembly 1514 locks the slide 1511 at a position with a gap between it and the battery cell group 23, the clamping assembly 1513 is also in the storage position, so as to prevent the clamping assembly 1513 from affecting the adapter welding process and the core assembly process.

[0155] After the core assembly process is completed and before the gluing process is performed, the clamping assembly 1513 can slide from the storage position to the use position, so that the clamping assembly 1513 clamps the portion of the battery cell group 23 close to the top cover 22 when the slide 1511 approaches the supporting mechanism 12.

[0156] After all the steps are completed, the slide 1511 moves away from the carrier assembly, and the clamping assembly 1513 slides from the use position to the storage position, thereby completing the reset of the slide 1511 and the clamping assembly 1513 .

[0157] In some other embodiments, the slide 1511 can slide along a third direction.

[0158] Continuing with Figures 8 and 9, in some more specific embodiments, the clamping sub-mechanism 151 further includes a second guide rail 1515, a locking block 1516, a locking member 1517, and an unlocking member 1518. The second guide rail 1515 is disposed on the slide 1511 and extends along the third direction. The clamping assembly 1513 is slidably disposed on the second guide rail 1515. The locking block 1516 is connected to the clamping assembly 1513. The locking member 1517 is rotatably disposed on the slide 1511 and abuts against the locking block 1516 when the clamping assembly 1513 is in the use position to lock the clamping assembly 1513. The unlocking member 1518 is slidably disposed on the slide 1511 and is used to push the locking member 1517 to rotate, thereby unlocking the clamping assembly 1513.

[0159] In this embodiment, in the third direction, the locking block 1516 and the locking member 1517 at least partially overlap, and the locking member 1517 and the clamping assembly 1513 are staggered with each other.

[0160] When the clamping assembly 1513 moves from the storage position to the use position, the locking block 1516 comes into contact with the locking member 1517, and the locking block 1516 pushes the locking member 1517 to rotate, so that the locking block 1516 moves to the side of the locking member 1517 away from the storage position.

[0161] When the clamping assembly 1513 is in the use position, the locking member 1517 stops the locking block 1516, thereby achieving the purpose of locking the clamping assembly 1513 to prevent the clamping assembly 1513 from moving to the storage position.

[0162] When all the processes are completed, the unlocking member 1518 slides and pushes the locking member 1517 to rotate, thereby avoiding the locking block 1516, so that the locking block 1516 can move to the storage position, thereby achieving the purpose of unlocking the clamping assembly 1513.

[0163] In some other more specific implementations, the locking member 1517 can be slidably disposed on the sliding seat 1511 .

[0164] Referring to Figure 11 , in some embodiments, the supporting mechanism 12 includes a top cover fixing assembly 121 and a second driving member 122. The top cover fixing assembly 121 is used to fix the top cover 22. The second driving member 122 is connected between the top cover fixing assembly 121 and the base 11 and is used to drive the top cover fixing assembly 121 toward or away from the base 11.

[0165] The top cover fixing assembly 121 fixes the top cover 22 to prevent the top cover 22 from deflecting or falling off.

[0166] During the process of the turning mechanism 14 driving the clamping mechanism 13 to turn, the second driving member 122 drives the top cover fixing assembly 121 to move closer to the base 11, thereby preventing the tab from being pulled and damaged. During this process, the distance between the top cover fixing assembly 121 and the base 11 is 2-3 mm, and of course other distances are possible and are not limited here.

[0167] After the clamping mechanism 13 is flipped to the second position, the second driving member 122 drives the top cover fixing assembly 121 to return to its original position.

[0168] In some other embodiments, the second driving member 122 may also drive the flip assembly away from the base 11 .

[0169] 11 , in some more specific embodiments, the supporting mechanism 12 further includes a top cover floating mechanism 123 . The top cover floating mechanism 123 is connected between the top cover fixing assembly 121 and the base 11 to provide a buffering force to the top cover fixing assembly 121 .

[0170] It is understood that during the adapter plate welding process, a force needs to be applied to the adapter plate toward the base 11 to reduce the gap between the adapter plate and the top cover 22, thereby improving the quality of the weld between the adapter plate and the top cover 22. Therefore, the top cover floating mechanism 123 is provided to float the top cover fixing assembly 121 in the third direction, thereby providing a buffering force to the top cover fixing assembly 121, thereby achieving floating compression and dimensional compensation.

[0171] In some other more specific embodiments, one end of the top cover floating mechanism 123 may be connected to the base 11 , and the other end may be adjacent to the top cover fixing assembly 121 .

[0172] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
