Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to a feeding mechanism. Background Technology

[0002] The feeding mechanism of an existing fully automatic battery casing machine generally includes a feeding component, a rounding component, and a flipping component. The flipping component is used to clamp and flip the battery cells on the battery cell conveyor line so that the two guide pins of the battery cell face upwards. The feeding component is used to transfer the flipped battery cells from the flipping component to the rounding component so that the rounding component can round the battery cells so that the battery cells can be pre-pressed into the lithium battery casing. The feeding component is also used to pre-press the rounded battery cells from the rounding component into the lithium battery casing on the turntable of the fully automatic battery casing machine. In practical applications, after the battery cells are conveyed to the flipping assembly via the cell conveyor line, the flipping assembly first clamps and flips the cells on the conveyor line so that the two guide pins of the cells face upwards. Then, the clamping module of the feeding assembly is moved by the translation cylinder to directly above the flipped cell on the flipping assembly. The clamping module then clamps the flipped cell on the flipping assembly and moves to directly above the rounding assembly. The clamping module then places the flipped cell on the rounding assembly, which rounds the cell. The clamping module then clamps the rounded cell and moves to directly above the lithium battery casing on the turntable. Finally, the clamping module pre-presses the rounded cell into the lithium battery casing on the turntable, thus completing the cell feeding operation. The aforementioned steps are then repeated.

[0003] Since a single clamping module is responsible for clamping the flipped cells from the flipping assembly, placing the clamped flipped cells onto the rounding assembly, clamping the rounded cells from the rounding assembly, and pre-pressing the clamped rounded cells into the lithium battery casing on the turntable, there is a long waiting time during the cell feeding process, whether it is the flipping assembly, the rounding assembly, or the turntable. This reduces production efficiency and increases production costs. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0032] Please refer to Figure 1 This utility model provides a feeding mechanism, including a feeding assembly 10, a rounding assembly 20, and a flipping assembly 30. The flipping assembly 30 is used to clamp and flip the battery cells on the battery cell conveying line so that the two guide pins of the battery cell face upwards. The feeding assembly 10 is used to transfer the flipped battery cells 100 on the flipping assembly to the rounding assembly 20 for rounding the battery cells 100, and to pre-press the rounded battery cells 100 on the rounding assembly 20 into the lithium battery casing on the turntable of the fully automatic casing machine.

[0033] The feeding assembly 10 includes a feeding rack 11, a translational linear module 12, a first clamping module 13, and a second clamping module 14.

[0034] The feeding rack 11 is located on one side of the rounding assembly 20, for example, behind the rounding assembly 20. The flipping assembly 30 is located, for example, to the left of the feeding rack 11. One end of the feeding rack 11 is close to the flipping assembly 30. In practical applications, the feeding rack 11 is mounted on the frame of the fully automatic shell-feeding machine. The translational linear module 12 is located on the side of the feeding rack 11 close to the rounding assembly 20, and part of the translational linear module 12 is located above the flipping assembly 30. The first clamping module 13 and the second clamping module 14 are both located on the side of the translational linear module 12 away from the feeding rack 11 and are distributed left and right at intervals along the length direction of the translational linear module 12. The first clamping module 13 and the second clamping module 14 are both located above the rounding assembly 20. The translational linear module 12 is used to drive the first clamping module 13 and the second clamping module 14 to move back and forth left and right along the length direction of the translational linear module 12. The first clamping module 13 is used to clamp the flipped battery cell 100 on the flipping assembly 30 and to place the clamped flipped battery cell 100 on the rounding assembly 20. The second clamping module 14 is used to clamp the rounded battery cell 100 on the rounding assembly 20 and to pre-press the clamped rounded battery cell 100 into the lithium battery casing on the turntable of the fully automatic casing machine. In actual application, the turntable is located in front of the feeding rack 11 and to the right of the rounding assembly 20. When the first clamping module 13 is directly above the flipped battery cell 100 on the flipping assembly 30, the second clamping module 14 is directly above the rounding assembly 20. When the first clamping module 13 is directly above the rounding assembly 20, the second clamping module 14 is directly above the lithium battery casing on the turntable.

[0035] Specifically, in combination Figure 2As shown, the translational linear module 12 includes a housing 121, a drive motor 122, a lead screw 123, a first nut (not shown in the figure), and a second nut (not shown in the figure). The housing 121 is located on the side of the feed rack 11 near the rounding assembly 20, and the side of the housing 121 away from the feed rack 11 has an opening communicating with the interior of the housing 121. The drive motor 122 is mounted on one end of the housing 121 via a mounting base 1211, and the output end of the drive motor 122 extends into the mounting base 121. The lead screw 123 is located inside the housing 121. One end of the housing 121 has a first through hole communicating with the interior of the housing 121, and the other end of the housing 121 has a second through hole communicating with the interior of the housing 121. One end of the lead screw 123 passes through the first through hole and extends into the mounting base 121, and is connected to the output end of the drive motor 121. The other end of the lead screw 123 is rotatably mounted in the second through hole via a bearing 1231. Both the first nut and the second nut are threaded into the lead screw 123 and are spaced apart laterally along the length of the lead screw 123. A first mounting block 124 is fitted around the outer periphery of the first nut, and a second mounting block 125 is fitted around the outer periphery of the second nut. Part of the first mounting block 124 extends out of the opening in the outer casing 121. A first clamping module 13 is located on the side of the first mounting block 124 away from the feed rack 11, part of the second mounting block 125 extends out of the opening in the outer casing 121, and a second clamping module 14 is located on the side of the second mounting block 125 away from the feed rack 11. A drive motor 122 drives the lead screw 123 to rotate, thereby causing the first nut and the second nut to reciprocate left and right along the length of the translational linear module 12. This, in turn, causes the first mounting block 124 and the second mounting block 125 to reciprocate left and right along the length of the translational linear module 12, and consequently, causes the first clamping module 13 and the second clamping module 14 to reciprocate left and right along the length of the translational linear module 12. The translational linear module 12 uses a drive motor 122 and a lead screw 123, which has high precision and can provide accurate linear motion for the first clamping module 13 and the second clamping module 14.

[0036] A guide member 1212 is provided on the side of the outer casing 121 away from the feed rack. A first guide groove 1241 is provided on the side of the first mounting block 124 away from the feed rack 11. A second guide groove 1251 is provided on the side of the second mounting block 125 away from the feed rack 11. Both the first guide groove 1241 and the second guide groove 1251 cooperate with the guide member 1212. The first mounting block 124 and the second mounting block 125 can move back and forth along the guide member 1212. The first guide groove 1241, the second guide groove 1251 and the guide member 1212 guide the movement of the first mounting block 124 and the second mounting block 125, which can improve the stability of the movement of the first mounting block 124 and the second mounting block 125, thereby improving the stability of the movement of the first clamping module 13 and the second clamping module 14.

[0037] The first mounting block 124 is slidably mounted on the inner wall of the outer casing 121 near the feed rack 11, and the second mounting block 125 is also slidably mounted on the inner wall of the outer casing 121 near the feed rack 11. Specifically, a guide rail 1213 extending along the length of the outer casing 121 is provided on the inner wall of the outer casing 121 near the feed rack 11. The first mounting block 124 has a first sliding block 1214 on the side near the feed rack 11, and the second mounting block 125 has a second sliding block 1215 on the side near the feed rack 11. Both the first sliding block 1214 and the second sliding block 1215 are slidably engaged with the guide rail 1213. This structure can further improve the smoothness of movement of the first mounting block 124 and the second mounting block 125, thereby further improving the smoothness of movement of the first clamping module 13 and the second clamping module 14.

[0038] Combination Figure 3As shown, both the first clamping module 13 and the second clamping module 14 include a first mounting plate 131, a second mounting plate 132, a feeding lifting cylinder 133, a feeding gripper cylinder 134, and two feeding grippers 135 arranged opposite each other. The first mounting plate 131 of the first clamping module 13 is located on the side of the first mounting block 124 of the translational linear module 12 away from the feeding frame 11, and the first mounting plate 131 of the second clamping module 14 is located on the side of the second mounting block 125 of the translational linear module 12 away from the feeding frame 11. The second mounting plate 132 is slidably disposed on the side of the first mounting plate 131 away from the translational linear module 12. The feeding lifting cylinder 133 is located on the side of the first mounting plate 131 away from the translational linear module 12 and above the second mounting plate 132. The output end of the feeding lifting cylinder 133 is connected to the side of the second mounting plate 132 away from the first mounting plate 131, and the feeding lifting cylinder 133 is used to drive the second mounting plate 132 to move up and down. The feeding gripper cylinder 134 is located on the side of the second mounting plate 132 away from the first mounting plate 131. The feeding gripper cylinder 134 protrudes from the bottom end of the second mounting plate 132. The two gripper cylinders 134 are used to drive the two feeding grippers 135 to open or close, so as to release or clamp the two guide pins 101 of the battery cell 100. The movement of the first mounting block 124 and the second mounting block 125 can respectively drive the first mounting plate 131 of the first clamping module 13 and the first mounting plate 131 of the second clamping module 14 to move left and right reciprocally along the length direction of the translational linear module 12. The first mounting plate 131 of the first clamping module 13 can drive the second mounting plate 132, the feeding up and down cylinder 133, the feeding claw cylinder 134, and the two feeding claws 135 of the first clamping module 13 to move left and right reciprocally along the length direction of the translational linear module 12. The first mounting plate 131 of the second clamping module 14 can drive the second mounting plate 132, the feeding up and down cylinder 133, the feeding claw cylinder 134, and the two feeding claws 135 of the second clamping module 14 to move left and right reciprocally along the length direction of the translational linear module 12. The up and down movement of the second mounting plate 132 can drive the up and down movement of the feeding claw cylinder 134 and the two feeding claws 135.

[0039] In this embodiment, the second mounting plate 132 is slidably disposed on the side of the first mounting plate 131 away from the translational linear module 12 via a slide rail assembly. This structure improves the stability of the up-and-down movement of the second mounting plate 132, thereby improving the stability of the up-and-down movement of the feeding gripper cylinder 134 and the two feeding grippers 135. The slide rail assembly includes a slide rail 1321 and a slider 1322 that slides with the slide rail 1321. The slide rail 1321 is disposed on the side of the first mounting plate 131 away from the translational linear module 12, and the length direction of the slide rail 1321 is the same as the height direction of the first mounting plate 131. The slider 1322 is disposed on the side of the second mounting plate 132 closer to the first mounting plate 131.

[0040] The first mounting plate 131 of the first clamping module 13 and the first mounting plate 131 of the second clamping module 14 are connected by a connector 136. The connector 136 is located in front of the translational linear module 12. The connector 136 ensures that the movement of the first clamping module 13 and the second clamping module 14 is synchronized.

[0041] Combination Figures 4 to 9 As shown, the rounding assembly 20 includes a rounding frame 21, a pneumatic finger cylinder 22 disposed at the top of the rounding frame 21, and four clamping blocks 23 disposed at the top of the pneumatic finger cylinder 22.

[0042] In practical applications, the round frame 21 is mounted on the frame of the fully automatic shell-feeding machine. Four clamping blocks 23 are arranged in a ring around the center of the top of the pneumatic finger cylinder 22, with each pair facing the other; specifically, two clamping blocks 23 are arranged front-to-back, and the other two are arranged left-to-right. Two chamfers 232 are provided between the end of the clamping block 23 closest to the center of the top of the pneumatic finger cylinder 22 and between the two sides of the clamping block 23. In this embodiment, the chamfers 232 are right angles. An arc-shaped groove 233 is provided at the end of the clamping block 23 closest to the center of the top of the pneumatic finger cylinder 22, and the arc-shaped groove 233 is located between the two chamfers 232. The pneumatic finger cylinder 22 is used to drive four clamping blocks 23 to move toward or away from the center of the top of the pneumatic finger cylinder 22. When the four clamping blocks 23 move to a predetermined position toward the center of the top of the pneumatic finger cylinder 22, a circular space 231 is formed between the arc grooves 233 of the four clamping blocks 22, and the two adjacent chamfers 232 of two adjacent clamping blocks 23 cooperate with each other.

[0043] Understandably, in other embodiments, the clamping blocks 23 may also be, for example, five or six, which can be set according to the actual situation.

[0044] Furthermore, the circular assembly 20 also includes a protective member 24 disposed at the top of the pneumatic finger cylinder 22. The bottom end of the protective member 24 has two cross-shaped first grooves 241, which are interconnected. The intersection of the two first grooves 241 corresponds to the center of the top of the pneumatic finger cylinder 22. Of the four clamping blocks 23, two are arranged opposite each other and are housed within one of the first grooves 241, while the other two are arranged opposite each other and are housed within the other first groove 241. The top of the protective member 24 has a second groove, which communicates with the intersection of the two first grooves 241. When the four clamping blocks 23 move towards the center of the top of the pneumatic finger cylinder 22 to a predetermined position, the circular space 231 formed between the arcuate grooves 233 of the four clamping blocks 22 is located at the intersection of the two first grooves 241 and corresponds to the second groove. The protective member 24 provides protection for the four clamping blocks 23.

[0045] A guide block 25 is provided in the second groove, and the top end of the guide block 25 extends out of the second groove and is fixed to the top end of the protective member 24. The guide block 25 has a guide channel 251 that runs through it along its axial direction. In this embodiment, the guide channel 251 is funnel-shaped and communicates with the cross intersection of the two first grooves 241. When the four clamping blocks 23 move to a predetermined position in the direction close to the center of the top end of the pneumatic finger cylinder 22, the circular space 231 formed between the arc grooves 233 of the four clamping blocks 23 corresponds to the guide channel 251. The guide channel 251 plays a guiding role in the placement of the battery cell 100, making it easier to place the battery cell 100 at the center of the top end of the pneumatic finger cylinder 22.

[0046] In this embodiment, the guide block 25 is T-shaped, with the vertical part of the guide block 25 disposed in the second groove, and the horizontal part of the guide block 25 extending out of the second groove and fixed to the top of the protective member 24.

Two flipping bearings 3211 are respectively provided in the two ends of the flipping mounting holes 32a. The flipping bearings 3211 are sleeved on the outer circumference of the flipping shaft 321 and provide rotational support for the flipping shaft 321. It can be understood that the number of flipping bearings 3211 can be set according to the actual situation. A flipping cylinder plate 322 is provided at one end of the flipping shaft 321 by means of sleeve, and a cam mounting plate 323 is provided at the other end of the flipping shaft 321 by means of sleeve. The tilting cylinder 33 is mounted on the tilting frame 31 and located above the tilting seat 32. The output end of the tilting cylinder 33 is connected to the top of the tilting seat 32. In this embodiment, the other side of the tilting frame 31 is provided with an L-shaped tilting cylinder block 312. The tilting cylinder block 312 protrudes above the tilting frame 31, and the tilting cylinder 33 is mounted on the tilting cylinder block 312.

[0048] The flipping clamping module is located on the side of the flipping cylinder plate 322 away from the flipping seat 32. The flipping clamping module is used to clamp the battery cell 100 on the battery cell conveying line and drive the battery cell 100 to flip. The flipping clamping module includes a flipping jaw cylinder 341 and two flipping jaws 342. The flipping jaw cylinder 341 is located on the side of the flipping cylinder plate 322 away from the flipping seat 32. The two flipping jaws 342 are both located at the bottom of the flipping jaw cylinder 341 and below the flipping cylinder plate 322. In actual application, the two flipping jaws 342 are located above the end of the battery cell conveying line. The flipping jaw cylinder 341 is used to drive the two flipping jaws 342 to close or open to clamp or release the battery cell 100.

[0049] A cam follower 324 is provided at the top of the cam mounting plate 323. A flipping connecting plate 313 is provided on the other side of the flipping frame 31. The flipping connecting plate 313 protrudes from the end of the flipping frame 31 near the feed rack 11. A flipping mounting plate 35 is disposed on the side of the flipping connecting plate 313 near the flipping frame 31 and is located between the flipping frame 31 and the feed rack 11. In this embodiment, the flipping mounting plate 35 and the flipping connecting plate 313 are integrally formed, and an L-shaped structure is formed between them. The flipping mounting plate 35 is provided with an L-shaped flipping cam groove 351. The cam follower 324 cooperates with the flipping cam groove 351 and can move along the flipping cam groove 351. The tilting cylinder 33 drives the tilting seat 32 to move up and down, thereby causing the tilting shaft 321, tilting cylinder plate 322, cam mounting plate 323, tilting gripper cylinder 341, and two tilting grippers 342 to move up and down. The up and down movement of the cam mounting plate 323 causes the cam follower 324 to move along the tilting cam groove 351. During the movement of the cam follower 324 along the tilting cam groove 351, the cam mounting plate 323 can be tilted around the axis of the tilting shaft 321. Thus, the tilting cylinder plate 322, tilting gripper cylinder 341, and two tilting grippers 342 can be tilted via the tilting shaft 321. The tilting angle is 90 degrees. When the two tilting grippers 342 tilt the battery cell 100 so that the two guide pins 101 of the battery cell 100 face upwards, the battery cell 100 is located below the first clamping module 13 and the second clamping module 14. The flipping action is achieved by using a cam follower 324 to move along the flipping cam groove 351, which requires no power and saves power costs.

[0050] The flip cam groove 351 includes a vertical section 352 and a horizontal section 353. The horizontal section 353 is located between the vertical section 352 and the flip connecting plate 313. The horizontal section 353 and the vertical section 352 are smoothly transitioned by an arc transition section 354. The arc transition section 354 facilitates the movement of the cam follower 324 from the vertical section 352 to the horizontal section 353 and from the horizontal section 353 to the vertical section 352.

[0051] With the above structure, in practical application, in the initial position, the cam follower 324 is located in the middle of the vertical section 352. When the battery cell 100 is transported to the area below the two flipping jaws 342 of the flipping assembly 30 via the battery cell conveyor line, the battery cell 100 is in a horizontal state with its two guide pins 101 facing forward. First, the flipping base 32 is driven downward by the flipping cylinder 33, which in turn drives the two flipping jaws 342 and the cam mounting plate 323 to move downward. This, in turn, drives the cam follower 324 to move downward along the vertical section 352 until the cam follower 324 is located at the lower end of the vertical section 352. At this point, the battery cell 100 is located between the two flipping jaws 342. Then, the flipping jaw cylinder 341 drives the two flipping jaws 342 to close and clamp the battery cell 100. Then, the flipping cylinder 33 drives the flipping seat 32 to move upward, thereby driving the two flipping grippers 342, the battery cell 100, and the cam mounting plate 323 to move upward. This, in turn, drives the cam follower 324 to move upward along the vertical section 352 until the cam follower enters the end of the horizontal section 353 near the vertical section 352 after passing through the arc transition section 354. During the process of the cam follower 324 entering the end of the horizontal section 353 near the vertical section 352, the cam follower 324 drives the cam mounting plate 323 to flip counterclockwise around the axis of the flipping shaft 321. This, in turn, drives the two flipping grippers 342 and the battery cell 100 to flip counterclockwise through the flipping shaft 321, so that the battery cell 100 is in a vertical state, and at this time, the two guide pins 300 of the battery cell 100 are facing upward.

[0052] Then, the translation linear module 12 drives the first clamping module 13 and the second clamping module 14 to move to the left, so that the first clamping module 13 is directly above the battery cell 100 on the flipping assembly 30 and the second clamping module 14 is directly above the round assembly 20. Then, the feeding cylinder 133 of the first clamping module 13 drives the two feeding jaws 135 to move downward until the two guide pins 101 of the battery cell 100 on the flipping assembly 30 are located between the two feeding jaws 135 of the first clamping module 13. The feeding gripper cylinder 134 of the first clamping module 13 drives the two feeding grippers 135 to close to clamp the two guide pins 101 of the battery cell 100 on the flipping assembly 30. Then, the flipping gripper cylinder 341 drives the two flipping grippers 342 to open to release the battery cell 100. Then, the feeding up and down cylinder 133 of the first clamping module 13 drives the two feeding grippers 135 and the battery cell 100 to move upward to the initial position. In this way, the first clamping module 13 can clamp the flipped battery cell 100 on the flipping assembly 30. Then, the translation linear module 12 drives the first clamping module 13 and the second clamping module 14 to move to the right, so that the first clamping module 13 is directly above the circular assembly 20 and the second clamping module 14 is directly above the lithium battery casing on the turntable. Then, the feeding upper and lower cylinders 133 of the first clamping module 13 drive the two feeding claws 135 and the battery cell 100 to move downward, so that the battery cell 100 is placed at the center of the top of the pneumatic finger cylinder 22 through the guide channel 251. At this time, the two guides of the battery cell 100 are... The needle 101 protrudes from the top of the guide block 25, and the battery cell 100 is located in the guide channel 251. Then, the feeding claw cylinder 134 of the first clamping module 13 drives the two feeding claws 135 to open and release the two guide needles 101 of the battery cell 100. Then, the feeding up and down cylinder 133 of the first clamping module 13 drives the two feeding claws 135 to move upward to the initial position. In this way, the first clamping module 13 can place the flipped battery cell 100 on the round assembly 20. Meanwhile, the flipping cylinder 33 drives the flipping seat 32 to move downward, thereby driving the two flipping grippers 342 and the cam mounting plate 323 to move downward. This causes the cam follower 324 to first enter the upper end of the vertical section 352 through the arc transition section 354, and then move downward along the vertical section 352 to the initial position. During the process of the cam follower 324 entering the upper end of the vertical section 352, the cam follower 324 can drive the cam mounting plate 323 to flip clockwise around the axis of the flipping shaft 321. This causes the two flipping grippers 342 to flip clockwise to the initial position through the flipping shaft 321. Then, the next battery cell 100 conveyed by the battery cell conveying line is gripped and flipped according to the aforementioned steps.

[0053] Then, the translation linear module 12 drives the first clamping module 13 and the second clamping module 14 so that the first clamping module 13 is positioned directly above the next cell 100 after flipping on the flipping assembly 30, and the second clamping module 14 is positioned directly above the rounding assembly 20. At the same time, the pneumatic finger cylinder 22 drives the four clamping blocks 23 to move towards the center of the top of the pneumatic finger cylinder 22 until they reach the predetermined position. At this time, the cell 100 is clamped by the four clamping blocks 23 and fixed in the circular space 231. During the movement of the four clamping blocks 23, the cell 100 can be squeezed through the bottom of the arc groove 233 of the four clamping blocks 23, thus achieving the rounding of the cell 100.

[0054] After the battery cell 100 is rounded, the four clamping blocks 23 are driven by the pneumatic finger cylinder 22 to move away from the center of the top of the pneumatic finger cylinder 22 to release the battery cell 100. Then, the two feeding jaws 135 are driven by the feeding up and down cylinder 133 of the second clamping module 14 to move downward until the guide pin 101 of the battery cell 100 is located between the two feeding jaws 135 of the second clamping module 14. Then, the two feeding jaws 135 are driven by the feeding jaw cylinder 134 of the second clamping module 14 to close and clamp the two guide pins 101 of the battery cell 100. Then, the two feeding jaws 135 and the battery cell 100 are driven by the feeding up and down cylinder 133 of the second clamping module 14 to move upward to the initial position. At this time, the battery cell 100 is located directly above the guide channel 251. In this way, the second clamping module 14 can clamp the rounded battery cell 100 on the rounding assembly 20. Then, the second clamping module 14 is driven to move to the right by the translation linear module 12 so that the second clamping module 14 is above the lithium battery casing on the turntable. Then, the two feeding jaws 135 and the battery cell 100 are driven to move downward by the feeding up and down cylinder 133 of the second clamping module 14 to pre-press the battery cell 100 into the lithium battery casing on the turntable. Then, the two feeding jaws 135 are driven to open by the feeding jaw cylinder 134 of the second clamping module 14 to release the two guide pins 101 of the battery cell 100. Then, the two feeding jaws 135 are driven to move upward to the initial position by the feeding up and down cylinder 133 of the second clamping module 14. In this way, the second clamping module 14 can pre-press the rounded battery cell 100 into the lithium battery casing on the turntable, and the feeding of the battery cell 100 is completed.

[0055] While the second clamping module 14 clamps the rounded battery cell 100 on the rounding assembly 20, the first clamping module 13 can clamp the next flipped battery cell 100 on the flipping assembly 30 in the aforementioned manner. While the second clamping module 14 pre-presses the clamped rounded battery cell 100 into the lithium battery casing on the turntable, the first clamping module 13 can place the clamped flipped battery cell 100 on the rounding assembly 20 in the aforementioned manner. Then the aforementioned steps can be repeated.

[0056] The feeding assembly 10 of this utility model includes a feeding rack 11, a translational linear module 12, a first clamping module 13, and a second clamping module 14. While the first clamping module 13 clamps the flipped battery cell 100 on the flipping assembly 30, the second clamping module 14 can clamp the rounded battery cell 100 on the rounding assembly 20. While the first clamping module 13 places the flipped battery cell 100 on the rounding assembly 20, the second clamping module 14 can pre-press the rounded battery cell 100 into the lithium battery casing on the turntable. The first clamping module 13 and the second clamping module 14 can perform material picking and unloading actions simultaneously. Compared with the existing method of using a single clamping module, the waiting time of the flipping assembly 30, the rounding assembly 20, and the turntable can be reduced, thereby improving production efficiency and reducing production costs.

[0057] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
