Description

Technical Field

[0001] This application relates to the field of battery manufacturing equipment technology, and in particular to a multifunctional battery fixture and battery production line. Background Technology

[0002] Currently, lithium batteries are widely used in industries such as laptops, power tools, and new energy vehicles. As these industries develop, the demand for lithium batteries continues to increase, which also leads to increasingly higher requirements for lithium batteries.

[0003] A prismatic laminated battery consists of a top cover, battery cells, and a casing. During the production and assembly process, the A and B battery cells are overlapped and placed on the top cover, and finally, the casing is fitted over the battery cells to complete the assembly. Generally, the assembly process for prismatic laminated batteries involves different stations on a battery assembly line processing the cells sequentially. The batteries are assembled on fixtures, and as the fixtures move, the batteries pass through different stations in sequence.

[0004] In this process, after the top cover is loaded onto the fixture, the battery cells need to be molded together at the top cover when they are loaded onto the top cover. During the battery cell loading process, an external transfer mechanism is required to transfer the battery cells to the top cover on the fixture. This necessitates the addition of a new station for transfer and positioning the battery cells, increasing the number of stations and the cost of the production line. Furthermore, the transfer accuracy of the battery cells is difficult to guarantee. In addition, the fixture needs to be equipped with a limiting structure to restrict the movement of the top cover relative to the fixture. Under the obstruction of the limiting structure, the battery cells are prone to interference with the limiting structure during the mold closing process, which affects the battery assembly process.

[0005] In summary, the assembly and processing of square stacked batteries presents several technical challenges, including high line construction costs, low cell loading accuracy, and potential interference between the cell molding process and the fixture structure, all of which affect battery assembly and processing.

[0082] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0083] This application provides a multifunctional battery fixture and battery production line. The multifunctional battery fixture uses a flip-top to transfer battery cells to the top cover. Because the movement trajectory of the flip-top is determined, the transfer accuracy of the battery cells is high. Furthermore, as the battery cells move with the flip-top, the limiting shell descends to a clearance height, exposing the top cover, thus preventing interference between the limiting shell and the flip-top or the battery cells. This application solves the technical problems of low battery cell loading accuracy and easy interference between the battery cell molding process and the structure on the fixture in related technologies.

[0084] Reference Figure 1 and Figure 2 A multifunctional battery fixture includes a base 1, a base 2, and a rotary drive assembly 9. The base 2 is mounted on a production line and can rotate on the line to move semi-finished batteries on the fixture to different workstations. The base 1 carries the batteries and is equipped with multiple mechanisms that act on the battery components. The base 1 is rotatably connected to the base 2 and is driven by the rotary drive assembly 9 to rotate relative to the base 2, facilitating the switching of the battery's orientation on the base 1. This allows for matching the processing requirements of different battery positions, simplifies the production line layout, and improves battery processing efficiency.

[0085] Reference Figures 1-5 The base 1 includes a mounting base 11 and a fixed base 12. The mounting base 11 is connected to the fixed base 12 and supports the top cover a. The fixed base 12 is rotatably connected to the base 2. Specifically, the center lines of the fixed base 12 and the base 2 are aligned, and the rotation axes of the fixed base 12 and the base 2 are also aligned with their center lines. In this embodiment, the fixed base 12 and the base 2 are rotatably connected by a bearing 94. The fixed base 12 includes a first connecting sleeve 121, and the base 2 includes a second connecting sleeve 21. The first connecting sleeve 121 and the second connecting sleeve 21 are respectively press-fitted with the inner ring and outer ring of the bearing 94 to complete the connection between the fixed base 12, the base 2, and the bearing 94.

[0086] Reference Figures 1-5The rotary drive assembly 9 includes a rotary gear 92, a rotary gear ring 91, and a rotary drive component 93. The rotary gear ring 91 is connected to one of the base 2 and the fixed seat 12, and the rotary gear 92 is rotatably connected to the other of the base 2 and the fixed seat 12. In this embodiment, the rotary gear ring 91 is connected to the base 2 and is sleeved on the second connecting sleeve 21, with an interference fit to the circumferentially outer side of the second connecting sleeve 21. The rotary gear 92 is rotatably connected to the fixed seat 12. Specifically, the second connecting sleeve 21 is connected to a mounting plate, the rotary gear 92 is rotatably connected to the mounting plate, and the rotary gear 92 meshes with the rotary gear ring 91. The rotary drive component 93 includes a servo motor, which is fixed on the mounting plate and is drivenly connected to the rotary gear 92. Thus, as the rotary drive component 93 drives the rotary gear 92 to rotate, the rotary gear 92 rolls on the rotary gear ring 92, thereby driving the fixed seat 12 to rotate relative to the base 2. The orientation of the battery on the base 1 can be switched to match the processing requirements of different battery positions, facilitate the layout of the production line, and improve the processing efficiency of the battery.

[0087] In some embodiments, the rotating gear ring 91 may also be located inside the second connecting sleeve 21, that is, the meshing point between the rotating gear 92 and the rotating gear ring 91 is located inside the second connecting sleeve 21, so as to make reasonable use of the internal space of the second connecting sleeve 21. In this embodiment, since the rotating gear ring 91 is located outside the second connecting sleeve 21, it facilitates the assembly and maintenance of the rotating gear ring 91 and the rotating gear 92.

[0088] Reference Figure 6 The multifunctional battery fixture also includes a power mechanism 8. The power mechanism 8 has one input end and multiple output ends, and the multiple output ends of the power mechanism 8 can be controlled independently. That is, multiple mechanisms on multiple battery fixtures can be independently controlled by one drive unit, which reduces the number of drive units and saves costs, and also saves space and reduces the volume occupied by the battery fixture.

[0089] Reference Figure 6 The power mechanism 8 includes a power mounting frame 81, a power drive component 82, and multiple power transmission assemblies 83. The power mounting frame 81 is fixed on the mounting base 12, and the power transmission assemblies 83 and the power drive component 82 are both connected to the power mounting frame 81. The power transmission assembly 83 includes a driving component 831, a driven component 832, and a clutch 833.

[0090] Reference Figure 6 Specifically, the driving member 831 includes a driving shaft, and multiple driving shafts are rotatably connected to the power mounting frame 81, with the axes of the multiple driving shafts aligned. The driven member 832 includes a driven shaft, and multiple driven shafts are rotatably connected to the power mounting frame 81, with the axes of the multiple driven shafts aligned with the axes of the multiple driving shafts, and the driving shafts are connected to the driven shafts via a clutch 833.

[0091] Reference Figure 6 Multiple drive shafts are connected by a power transmission assembly 84. The power transmission assembly 84 includes a belt drive assembly, a chain drive assembly, or a gear drive assembly. In this embodiment, the power transmission assembly 84 includes a belt drive assembly, which includes multiple power transmission pulleys 841 and a power transmission belt 842. The number of power transmission pulleys 841 corresponds to the number of drive shafts. The multiple power transmission pulleys 841 are respectively fixedly sleeved on the multiple drive shafts, and the power transmission belt 842 is wound around the multiple power transmission pulleys 841. Therefore, under the transmission connection of the belt drive assembly, the multiple drive shafts can rotate synchronously.

[0092] Reference Figure 6 The power drive component 82 includes a servo motor, which is fixedly connected to the power mounting bracket 81 and driven by an active component 831. This means that one power drive component 82 can drive multiple active shafts to rotate synchronously. Power is then transmitted to the driven shafts by controlling the opening and closing of multiple clutches 833. Multiple driven shafts can then be independently driven by one power drive component 82 under the control of the multiple clutches 833, enabling one power drive component 82 to drive multiple mechanisms independently, thus saving on the cost of battery fixtures.

[0093] Reference Figure 6 In this embodiment, there are three active members 831 and three driven members 832. It can be understood that the three driven members 832 are all output ends of the power mechanism 8, namely the first output end, the second output end and the third output end of the power mechanism 8.

[0094] Reference Figure 2 The mounting base 11 includes a support portion 111 and a connecting portion 112, which are bolted together or integrally formed. The support portion 111 supports the top cover a, and the connecting portion 112 is connected to the fixing base 12. When the top cover a is supported by the support portion 111, the width direction of the top cover a is set along a third direction. In this embodiment, the third direction is the Y-axis direction in the figure.

[0095] Reference Figure 1 and Figure 7The multifunctional battery fixture also includes a limiting mechanism 3, which includes a limiting shell 31 and a lifting assembly 32. The limiting shell 31 is sleeved on the support portion 111 of the mounting base 11, and the limiting shell 31 is slidably disposed on the support portion 111 along a first direction. In this embodiment, the first direction is the Z-axis direction in the figure, that is, the limiting shell 31 is vertically slidably disposed on the support portion 111. The limiting shell 31 slides and switches between a limiting height and a clearance height. The top surface of the limiting shell 31 has an installation port 311. The top cover a is fed to the support portion 111 through the installation port 311 and is supported by the top surface of the support portion 111. The inner side of the limiting shell 31 contacts the side of the top cover a. Therefore, after the top cover a passes through the installation port 311, the limiting shell 31 positions the top cover a and also restricts the top cover a from moving freely relative to the support portion 111, so as to determine the position of the top cover a on the battery fixture.

[0096] When the limiting shell 31 is at the limiting height, the limiting shell 31 is higher than the mounting base 11, so that the top cover a is limited by the inner side of the limiting shell 31 abutting against the side of the top cover a. When the limiting shell 31 is at the clearance height, the limiting shell 31 is lower than the mounting base 11, so that the top cover a is exposed.

[0097] Reference Figure 11 and Figure 12 The lifting assembly 32 includes a lifting end that moves along a first direction and is connected to the limiting shell 31. In this embodiment, the lifting assembly 32 includes a lifting connector 321, a lifting connecting rod 322, a lifting transmission gear 323, and a lifting drive gear 324. The lifting connecting rod 322 is positioned along the first direction, and its top end is connected to the limiting shell 31; that is, in this embodiment, the lifting end is the lifting connecting rod 322. The lifting connector 321 is connected to the bottom end of the lifting connecting rod 322. Both the lifting transmission gear 323 and the lifting drive gear 324 are rotatably connected to the fixed base 12 and are meshed together. The end face of the lifting transmission gear 323 has a lifting connecting groove 323a, and a portion of the lifting connector 321 is located within the lifting connecting groove 323a. As the lifting transmission gear 323 rotates, the groove wall of the lifting connecting groove 323a pushes the lifting connector 321 to move, thereby causing the limiting shell 31 to rise and fall in the first direction.

[0098] In this embodiment, the first output end of the power mechanism 8 is connected to the lifting drive gear 324. In this embodiment, a driven shaft of the power mechanism 8 is connected to the lifting drive gear 324 via a coupling. In other embodiments, a driven shaft of the power mechanism 8 is connected to the lifting drive gear 324 via gear meshing, belt drive, or chain drive. The power mechanism 8 drives the lifting drive gear 324 to rotate, causing the lifting transmission gear 323 to rotate accordingly. This causes the lifting connecting member 321 and the lifting connecting rod 322 to rise and fall due to the groove wall of the lifting connecting groove 323a, thereby completing the lifting movement of the limiting shell 31.

[0099] Reference Figure 11 and Figure 12 In this embodiment, the lifting connector 321 includes a roller component, which is rotatably connected to the lifting connecting rod 322. The roller component contacts the lifting connecting groove 323a, which can replace sliding friction with rolling friction. The lifting connecting groove 323a can push the lifting connector 321 to move more smoothly and reduce the wear of the lifting connector 321.

[0100] Since the limiting shell 31 can be raised and lowered, when the battery cell b is being fed, the limiting shell 31 can be lowered to expose the top cover a. The limiting shell 31 no longer blocks the top cover a, which facilitates the feeding of the battery cell b. When the battery cell b is closed at the top cover a, it will not interfere with the limiting shell 31.

[0101] Reference Figure 7 and Figure 11 Furthermore, the lifting assembly 32 also includes multiple sets of lifting guide assemblies 325, which are evenly arranged on opposite sides of the limiting shell 31. Each lifting guide assembly 325 includes a lifting guide sleeve 3251 and a lifting guide rod 3252. The lifting guide sleeve 3251 is fixed to the limiting shell 31; specifically, the lifting guide sleeve 3251 and the limiting shell 31 are integrally formed, and the axial direction of the lifting guide sleeve 3251 is along a first direction. The bottom end of the lifting guide rod 3252 is fixed to the connecting portion 112 of the mounting base 11; specifically, the lifting guide rod 3252 is welded to the connecting portion 112 of the mounting base 11, and the top end of the lifting guide rod 3252 passes through the lifting guide sleeve 3251. Under the guiding action of the lifting guide rod 3252 and the lifting guide sleeve 3251, the movement of the limiting shell 31 is more stable and less prone to deviation.

[0102] Reference Figure 7 and Figure 11Furthermore, the lifting assembly 32 also includes multiple lifting elastic elements (not shown in the figure). The deformation direction of the lifting elastic elements is arranged along a first direction, and their two ends are respectively connected to the connection portion 112 of the limiting shell 31 and the mounting base 11. In this embodiment, the lifting elastic element includes a spring, and the two ends of the spring abut against the inner top surface of the lifting guide sleeve 3251 and the top surface of the lifting guide rod 3252, respectively. The elastic force of the lifting elastic element keeps the limiting shell 31 at its highest position, so as to keep the top cover a inside the limiting shell 31.

[0103] Reference Figure 7 and Figure 11 Furthermore, the lifting assembly 32 also includes multiple lifting guide blocks 1111, which are fixed to the side of the support portion 111 of the mounting base 11. Multiple lifting guide grooves 313 are provided on the side wall of the limiting shell 31, and the lifting guide blocks 1111 are slidably disposed in the lifting guide grooves 313, so as to further improve the stability of the limiting shell 31 during lifting and sliding through the cooperation of the lifting guide blocks 1111 and the lifting guide grooves 313.

[0104] Reference Figure 11 and Figure 12 In this embodiment, the span of the lifting connecting groove 323a in the first direction is greater than the length of the lifting connecting member 321 in the first direction. When the lifting connecting groove 323a pushes the lifting connecting member 321 downward, the top surface of the lifting connecting groove 323a contacts the lifting connecting member 321, and a distance is left between the bottom surface of the lifting connecting groove 323a and the lifting connecting member 321. The lifting elastic member is provided to support the limiting shell 31, preventing the limiting shell 31 from sliding down under the action of gravity.

[0105] In addition, since the span of the lifting connecting groove 323a in the first direction is greater than the length of the lifting connecting member 321 in the first direction, when the shell c is pressed in the shell insertion station, since the lifting connecting member 321 has downward space in the lifting connecting groove 323a, the shell c can push the limiting shell 31 down. Therefore, when pressing the shell c, it is not necessary to push the lifting connecting member 321 down through the lifting connecting groove 323a at the same time, which simplifies the cooperation between the mechanisms.

[0106] Reference Figures 8-10Optionally, the mounting opening 311 of the limiting shell 31 has a stepped groove 312 on its side wall. The side wall of the stepped groove 312 is adapted to abut against the outer side wall of the battery casing c, and the bottom of the stepped groove 312 is adapted to abut against the end face of the battery casing c. When pressing the casing c, when the end of the casing c abuts against the bottom of the stepped groove 312, the outer side wall of the casing c abuts against the side wall of the stepped groove 312. Therefore, the groove wall of the stepped groove 312 restricts the free movement of the casing c, which facilitates maintaining the vertical pressing movement of the casing c. During pressing, under the limitation of the groove wall of the stepped groove 312, the casing c will not slip against the limiting shell 31, ensuring accurate pressing of the casing c and improving the battery assembly quality.

[0107] Reference Figure 13 and Figure 14 Furthermore, in some embodiments, the mounting base 11 includes two mounting halves 113, which are sequentially arranged in a third direction, and both mounting halves 113 are slidably mounted on the fixed base 12 in the third direction, sliding closer to or further away from each other. The fixed base 12 is provided with a guide rail arranged in a third direction, and the mounting halves 113 are slidably mounted on the guide rail to improve the stability of the sliding of the mounting halves 113.

[0108] The top cover a is supported by the top surfaces of the two mounting halves 113. The width of the top cover a varies depending on its specifications. Therefore, the distance between the two mounting halves 113 is changed to accommodate the support of top covers a of different widths.

[0109] Reference Figure 13 and Figure 14 Each of the two mounting halves 113 has multiple grooves 1132 and multiple protrusions 1131 on its facing sides. The protrusions 1131 and grooves 1132 are arranged one-to-one in the third direction, and the two mounting halves 113 form a plug-in fit through the protrusions 1131 and grooves 1132. When the distance between the two mounting halves 113 is changed, the overall integrity of the two mounting halves 113 is better due to the arrangement of the protrusions 1131 and grooves 1132.

[0110] Reference Figure 13 , Figure 14 and Figure 15 The multifunctional battery fixture also includes an adjustment mechanism 4, which adjusts the distance between the two mounting halves 113. The adjustment mechanism 4 includes an adjustment transmission assembly 42 and multiple sets of adjustment assemblies 41. The adjustment transmission assembly 42 connects the multiple sets of adjustment assemblies 41 to ensure synchronous movement. In this embodiment, two sets of adjustment assemblies 41 are provided, spaced apart in a second direction, which is the X-axis direction in the figure. When the top cover a is located on the battery fixture, the length direction of the top cover a is also along the second direction.

[0111] Reference Figure 13 , Figure 14 and Figure 15 Specifically, the adjustment assembly 41 includes an adjusting bidirectional lead screw 411 and two adjusting connectors 412. The adjusting bidirectional lead screw 411 is rotatably connected to the fixed base 12. In this embodiment, the adjusting bidirectional lead screw 411 is rotatably connected to the power mounting bracket 81, and the length direction of the adjusting bidirectional lead screw 411 is arranged along a third direction. The adjusting bidirectional lead screw 411 passes through two mounting half-bases 113. The two adjusting connectors 412 are respectively connected to the two mounting half-bases 113, and the two adjusting connectors 412 are respectively threaded to both ends of the adjusting bidirectional lead screw 411. Since the sliding direction of the mounting half-bases 113 is determined, the sliding direction of the adjusting connectors 412 is also determined, and the adjusting connectors 412 can only move along a third direction. As the adjusting bidirectional lead screw 411 rotates, it can drive the two adjusting connectors 412 to move closer or further apart, so as to adjust the distance between the two mounting half-bases 113 to accommodate top covers a of different widths.

[0112] Reference Figure 13 , Figure 14 and Figure 15 The adjusting connector 412 includes an adjusting connecting sleeve that passes through the mounting half 113 and is connected to the mounting half 113 via a bolt assembly. The adjusting connecting sleeve is fitted onto the adjusting double-acting screw 411 and threadedly engages with the adjusting double-acting screw 411 so as to move with the rotation of the adjusting double-acting screw 411.

[0113] Reference Figures 13-16 Specifically, the adjusting transmission assembly 42 includes an adjusting drive wheel 422, an adjusting transmission belt 423, and multiple adjusting transmission wheels 421. The number of adjusting transmission wheels 421 corresponds to the number of adjusting bidirectional lead screws 411. In this embodiment, there are two adjusting transmission wheels 421, which are respectively fixedly sleeved on multiple adjusting bidirectional lead screws 411, and are positioned near the middle of the adjusting bidirectional lead screws 411. The adjusting drive wheel 422 is connected to the second output end of the power mechanism 8. In this embodiment, the adjusting drive wheel 422 is sleeved on a driven shaft of the power mechanism 8. The adjusting transmission belt 423 is wound around the adjusting drive wheel 422 and the multiple adjusting transmission wheels 421.

[0114] This configuration allows the power mechanism 8 and the adjustment transmission assembly 42 to drive multiple adjusting bidirectional lead screws 411 to rotate, thereby adjusting the movement of the connecting piece 412 to move the mounting half seat 113 closer to and further away. This facilitates the adjustment of the support width of the mounting seat 11 for the top cover a, adapting to the assembly of top covers a of different sizes. When dealing with batteries of different specifications, there is no need to replace the entire mounting seat 11, saving processing costs.

[0115] Reference Figures 13-16 In some embodiments, the limiting shell 31 may also consist of two limiting half-shells 314, which are symmetrically arranged and sequentially positioned in the third direction. The two limiting half-shells 314 have multiple limiting connection holes and multiple limiting connection rods on their mutually facing sides. The length directions of the limiting connection holes and the limiting connection rods are all along the third direction. The two limiting half-shells 314 form a plug-in fit through the limiting connection holes and the limiting connection rods, allowing them to rise and fall synchronously in the third direction without easily becoming misaligned. Furthermore, since both limiting half-shells 314 can be connected to the two mounting halves 113 respectively via the lifting guide assembly 325, the distance between the two limiting half-shells 314 is adjusted synchronously when the distance between the two mounting halves 113 is adjusted. This is suitable for limiting the top cover a of different specifications. When processing batteries of different sizes and specifications, there is no need to replace the limiting shell 31, saving processing costs.

[0116] Reference Figure 1 and Figure 17 The multifunctional battery fixture also includes two sets of flipping mechanisms 5, both of which are connected to the connecting part 112 of the mounting base 11. The two sets of flipping mechanisms 5 are spaced apart in a third direction and are located on opposite sides of the limiting shell 31. The two sets of flipping mechanisms 5 are used to carry the battery cell b and drive the battery cell b to flip to the top cover a. The two sets of flipping mechanisms 5 are symmetrically arranged on the mounting base 11. The two sets of flipping mechanisms 5 drive the two battery cells b to flip, and make the two battery cells b change from a horizontal state to a vertical state. When the battery cells b are in the vertical state, the two battery cells b are close together to complete the mold closing operation. At the same time, both battery cells b are flipped to the top cover a and supported by the top cover a on the mounting base 11.

[0117] Reference Figure 17 , Figure 18 and Figure 19 The flipping mechanism 5 includes a flipping support frame 51, a flipping base 52, and a flipping assembly 53. The flipping support frame 51 is connected to the connecting portion 112 of the mounting base 11. The flipping base 52 is used to carry the battery cell b and is rotatably connected to the flipping support frame 51. The rotation axis of the flipping base 52 is arranged along a second direction. The flipping assembly 53 includes a flipping end, which is connected to the flipping base 52 to drive the flipping base 52 to rotate.

[0118] Reference Figure 17 , Figure 18 and Figure 19The flipping assembly 53 includes a flipping shaft 531, a flipping gear set 532, and a flipping drive component 533. The flipping shaft 531 is positioned along a second direction along its length and is rotatably connected to a flipping support frame 51. The flipping seat 52 is fixed to the flipping shaft 531; that is, the flipping shaft 531 is the flipping end of the flipping assembly 53. The flipping gear set 532 is mounted on the flipping support frame 51, and its output end is drively connected to the flipping shaft 531. The flipping drive component 533 includes a servo motor, which is fixed to the flipping support frame 51. The flipping drive component 533 is drively connected to the input end of the flipping gear set 532, thereby driving the flipping shaft 531 and the flipping seat 52 to rotate via the flipping drive component 533 and the flipping gear set 532.

[0119] Reference Figure 17 , Figure 18 and Figure 19 The tilting gear set 532 includes a tilting drive gear 5321, a tilting transmission gear 5322, and a tilting connecting gear 5323. The tilting drive gear 5321, tilting transmission gear 5322, and tilting connecting gear 5323 are all rotatably connected to the tilting support frame 51 and mesh sequentially. Specifically, the tilting drive component 533 is drivenly connected to the tilting drive gear 5321, and the tilting connecting gear 5323 is fixedly sleeved on the tilting shaft 531. The number of tilting transmission gears 5322 can be set as needed, with multiple gears. Through gear transmission, the torque output of the tilting drive component 533 is increased to support the power of the tilting drive component 533 in driving the tilting seat 52 to tilt.

[0120] Reference Figure 17 , Figure 18 and Figure 19 Preferably, the flip connecting gear 5323 includes a half gear. Since the rotation angle of the flip base 52 is 90 degrees, the rotation angle of the flip connecting gear 5323 is also 90 degrees. Therefore, the flip connecting gear 5323, which is arranged in a half gear shape, can support the flip base 52 to complete the flipping. In addition, the flip connecting gear 5323, which is arranged in a half gear shape, can reduce the space occupied by the flipping component 53 and avoid interference with other mechanisms on the battery fixture.

[0121] The flipping assembly 53 drives the flipping base 52 to rotate. The two flipping bases 52 rotate from a horizontal state to a vertical state, and the battery cell b is moved to the top cover a. The two battery cells b overlap to complete the mold closing. Since the movement trajectory of the flipping base 52 is determined, the flipping base 52 can drive the battery cell b to the same position each time, so as to improve the accuracy of battery cell b transfer. The battery cell b can be accurately transferred to the top cover a, which improves the assembly accuracy of the battery.

[0122] Reference Figures 8-10The flipping process of cell b is as follows: The lifting assembly 32 first lowers the limiting shell 31 to the clearance height, causing the top cover a to extend from the mounting opening 311 of the limiting shell 31. At this time, the limiting shell 31 does not obstruct the top cover a, and it is not on the flipping path of the flipping base 52 and cell b. The flipping assembly 53 drives the flipping base 52 to rotate, thus flipping cell b to the top cover a. The two cells b overlap and fit together at the top cover a, and cell b is supported by the top cover a. During the flipping process, neither cell b nor the flipping base 52 interferes with the limiting shell 31, ensuring the normal assembly of the battery.

[0123] Reference Figure 17 , Figure 18 and Figure 19 Optionally, the flipping base 52 includes a base 521 and a side seat 522. The base 521 is rotatably connected to the flipping support frame 51. The length direction of the base 521 is set along a second direction, and when the base 521 is in a horizontal state, its width direction is set along a third direction. The side seat 522 is located on one side of the base 521, and the base 521 and the side seat 522 are arranged sequentially in the width direction of the base 521. When both bases 521 are in a horizontal state, the two side seats 522 are located on opposite sides of the two bases 521. When the base 521 carries the battery cell b, the side seat 522 also contacts one side of the battery cell b to position the battery cell b on the base 521, ensuring that the flipped battery cell b is at the top cover a, and ensuring that the two battery cells b can be aligned and molded after flipping.

[0124] Reference Figure 17 , Figure 18 and Figure 19 The flip-up seat 52 also includes multiple width-adjusting guide rods 524. One end of each width-adjusting guide rod 524 is fixed to the side of the loading base 521, and the length of the width-adjusting guide rod 524 is arranged along the width direction of the loading base 521. The width-adjusting guide rod 524 passes through the loading side seat 522 so that the loading side seat 522 is slidably connected to the loading base 521, and the sliding direction of the loading side seat 522 is in the width direction of the loading base 521.

[0125] Reference Figure 17 , Figure 18 and Figure 19Furthermore, the flip seat 52 also includes a width adjustment component 523. The fixed end of the width adjustment component 523 is connected to the loading base 521, and the width adjustment drive end moves along the width direction of the loading base 521 and connects to the loading side seat 522. In this embodiment, the width adjustment component 523 includes a toothless screw 5231 and a toothless nut (not shown in the figure). The length direction of the toothless screw 5231 is arranged along the width direction of the loading base 521, and one end of the toothless screw 5231 is rotatably connected to the loading base 521. The toothless screw 5231 passes through the loading side seat 522, and the toothless nut is sleeved on the toothless screw 5231 and cooperates with the toothless screw 5231. The toothless nut and the loading side seat 522 can be adjusted by rotating the toothless screw 5231 to drive the toothless nut and the loading side seat 522 to move in the width direction of the loading base 521. A knob 5232 may be connected to the end of the toothless screw 5231 away from the load base 521 to facilitate rotation of the toothless screw 5231. In other embodiments, the width adjustment assembly 523 may also include a linear motor or a lead screw mechanism to achieve automatic adjustment.

[0126] By adjusting the distance between the base 521 and the side seat 522, it is possible to accommodate battery cells b of different sizes and specifications, facilitating the positioning of different battery cells b and ensuring that the battery cell b is placed on the top cover a after being flipped over. After the battery cell b is loaded onto the base 521, it comes into contact with the side seat 522, thus completing the precise loading of the battery cell b.

[0127] Reference Figure 17 , Figure 19 and Figure 20 Furthermore, the multifunctional battery fixture also includes a clamping and limiting assembly 6, which includes a clamping and limiting shaft 61, a clamping and limiting drive (not shown in the figure), and a plurality of clamping and limiting elements 62.

[0128] Reference Figure 17 , Figure 19 and Figure 20 Specifically, the axial direction of the clamping and limiting shaft 61 is arranged along the second direction and is rotatably connected to the load side seat 522. The clamping and limiting drive includes a servo motor, which is fixed to the load side seat 522 and drivenly connected to the clamping and limiting shaft 61. The clamping and limiting drive can be placed inside the load side seat 522. Multiple clamping and limiting members 62 are all fixed to the circumferential side of the clamping and limiting shaft 61 so as to rotate with the rotation of the clamping and limiting shaft 61.

[0129] After the battery cell b is placed on the carrier base 521, the clamping and limiting drive rotates, causing the clamping and limiting shaft 61 and the clamping and limiting member 62 to rotate. The clamping and limiting member 62 presses against the side of the battery cell b facing away from the carrier base 521, thus clamping the battery cell b with the clamping and limiting member 62 and the carrier base 521, restricting the movement of the battery cell b relative to the carrier base 521. In particular, during the flipping process of the carrier base 521, the battery cell b, clamped by the clamping and limiting member 62 and the carrier base 521, can rotate together with the carrier base 521.

[0130] Reference Figure 17 , Figure 19 and Figure 20 Furthermore, the clamping and limiting member 62 includes two first clamping and limiting members and a plurality of second clamping and limiting members. The first and second clamping and limiting members are arranged along a second direction, and the plurality of second clamping and limiting members are located between the two first clamping and limiting members. When clamping the battery cell b, the first clamping and limiting members contact the edge of the battery cell b, while the second clamping and limiting members contact the middle position of the battery cell b.

[0131] Reference Figure 17 , Figure 19 and Figure 20 The first clamping and limiting component includes a clamping and limiting plate 621 and a clamping and limiting side plate 622, while the second clamping and limiting component only includes the clamping and limiting plate 621. The clamping and limiting plate 621 is fixed to the clamping and limiting shaft 61, and the clamping and limiting plate 621 contacts the battery cell b to cooperate with the carrier base 521 to clamp the battery cell b. The clamping and limiting plate 621 has a clearance groove to prevent interference between the clamping and limiting plate 621 and the clamping and limiting shaft 61 or the carrier side plate 522 during the rotation of the clamping and limiting plate 621, ensuring that the clamping and limiting plate 621 is pressed firmly on the battery cell b.

[0132] Furthermore, a rubber buffer pad is adhered to the end of the clamping limit plate 621, which contacts the battery cell b to avoid damaging the battery cell b and ensure that the battery cell b is clamped.

[0133] The clamping and limiting side plate 622 is welded to or integrally formed with the clamping and limiting plate 621. When the first clamping and limiting member presses against the battery cell b, the clamping and limiting side plate 622 and the clamping and limiting plate 621 respectively contact the adjacent two sides of the battery cell b. Since there are two first clamping and limiting members, there are two clamping and limiting side plates 622, and the two clamping and limiting side plates 622 are spaced apart in the second direction and respectively abut against the opposite two sides of the battery cell b. Thus, when the battery cell b is placed on the carrier base 521, the clamping and limiting side plate 622 can restrict the movement of the battery cell b in the second direction, so that the battery cell b is more stably positioned on the carrier base 521.

[0134] Reference Figure 1 , Figures 21-23The multifunctional battery fixture also includes a clamping and limiting mechanism 73, which is used to limit the top cover a to prevent the top cover a and the battery cell b on the top cover a from moving relative to the mounting base 11. When the battery fixture moves to different work stations, it ensures that the position of the semi-finished battery on the battery fixture does not change relative to the battery fixture.

[0135] Reference Figure 1 , Figures 21-23 Specifically, the clamping and limiting mechanism 73 includes a clamping and limiting mounting frame 71 and multiple sets of clamping and limiting components 72. The clamping and limiting mounting frame 71 is fixed on the fixed base 12, and the multiple sets of clamping and limiting components 72 are disposed on the clamping and limiting mounting frame 71. In this embodiment, the clamping and limiting components 72 include two sets, which are spaced apart in the second direction to clamp the two ends of the top cover a, thereby limiting the movement of the top cover a relative to the mounting base 11.

[0136] Reference Figures 21-23 The clamping and limiting assembly 72 includes a clamping and limiting bidirectional lead screw 721 and two clamping and limiting members 722. The length direction of the clamping and limiting bidirectional lead screw 721 is arranged along a third direction and is rotatably connected to the clamping and limiting mounting frame 71. Both clamping and limiting members 722 are slidably disposed in the clamping and limiting mounting frame 71 along a third direction and are threadedly engaged with both ends of the clamping and limiting bidirectional lead screw 721. As the clamping and limiting bidirectional lead screw 721 rotates, the two clamping and limiting members 722 move closer to or further away from each other. The two clamping and limiting members 722 are located on opposite sides of the support portion 111 of the mounting base 11. The two clamping and limiting members 722 approach each other and abut against opposite sides of the top cover a to clamp the top cover a.

[0137] Reference Figures 21-23 The clamping and limiting mechanism 73 also includes multiple limiting sleeves, which are fixed to the clamping and limiting mounting bracket 71, and the axial direction of the limiting sleeves is arranged along a third direction. The clamping and limiting component 722 includes a gripper 7221 and a mating sleeve 7222, which are integrally formed. The mating sleeve 7222 is sleeved on the clamping and limiting bidirectional lead screw 721, and the mating sleeve 7222 passes through the limiting sleeve. The outer surface of the mating sleeve 7222 has multiple limiting grooves 722a arranged along a second direction in length, and the inner surface of the limiting sleeve has multiple limiting strips 73a arranged along the second direction in length. The limiting strips 73a are slidably disposed within the limiting strips 73a, so that with the cooperation of the limiting strips 73a and the limiting grooves 722a, the mating sleeve 7222 and the gripper 7221 can only slide along a third direction. When the clamping and limiting bidirectional lead screw 721 rotates, it can drive the mating sleeve 7222 and the clamping movement to clamp the top cover a through the two jaws 7221, thereby limiting the movement of the top cover a relative to the mounting base 11, so as to facilitate the processing of semi-finished batteries on the battery fixture at different workstations.

[0138] Reference Figures 21-23 The clamping and limiting mechanism 73 also includes a clamping and limiting transmission assembly 74, which connects multiple clamping and limiting bidirectional lead screws 721 to ensure that multiple parts of the top cover a are clamped simultaneously.

[0139] Reference Figures 21-23 Specifically, the clamping and limiting transmission assembly 74 includes a clamping and limiting drive wheel 741, a clamping and limiting transmission belt 744, multiple clamping and limiting driven wheels 742, and multiple clamping and limiting guide wheels 743. The number of multiple clamping and limiting driven wheels 742 corresponds to the number of clamping and limiting bidirectional lead screws 721. In this embodiment, three are provided. The multiple clamping and limiting driven wheels 742 are respectively fixedly sleeved on the multiple clamping and limiting bidirectional lead screws 721 and are located near one end of the clamping and limiting bidirectional lead screws 721. The clamping and limiting drive wheel 741 and multiple clamping and limiting guide wheels 743 are rotatably connected to the clamping and limiting mounting frame 71. The clamping and limiting transmission belt 744 is wound around the clamping and limiting drive wheel 741, the clamping and limiting driven wheel 742, and the clamping and limiting guide wheels 743, so that multiple clamping and limiting bidirectional lead screws 721 rotate synchronously through belt transmission. That is, multiple sets of clamping and limiting components 72 can act synchronously on the top cover a, improving the stability of clamping the top cover a. In addition, the power transmission by belt facilitates the rational use of space and avoids interference with other structures of the battery fixture.

[0140] The third output end of the power mechanism 8 is connected to the clamping and limiting drive wheel 741. In this embodiment, the clamping and limiting drive wheel 741 is fixedly sleeved on a driven shaft of the power mechanism 8 so as to drive the clamping and limiting bidirectional lead screw 721 to rotate through the power mechanism 8.

[0141] It should be noted that when the clamping and limiting component 72 is clamped to the top cover a, the limiting shell 31 is always lower than the top cover a, so the limiting shell 31 does not interfere with the clamping and limiting component 72. When pressing the outer shell c, the clamping and limiting component 72 is in the unlocked state. At this time, the limiting shell 31 returns to its original position to limit the top cover a, and the clamping and limiting component 72 does not affect the pressing operation of the outer shell c.

[0142] This application provides a multifunctional battery fixture, wherein after the top cover a is fed into the mounting base 11, it is supported by the mounting base 11. The two battery cells b can also be fed into the two flip seats 52 respectively along with the top cover a, so as to shorten the feeding time of the battery components. The top cover a passes through the mounting opening 311 of the limiting shell 31 and is located on the mounting base 11. The limiting shell 31 restricts the position of the top cover a and determines the position of the top cover a.

[0143] The flipping assembly 53 drives the flipping base 52 to rotate. The two flipping bases 52 rotate from a horizontal state to a vertical state, and the battery cell b is moved to the top cover a. The two battery cells b overlap to complete the mold closing. Since the movement trajectory of the flipping base 52 is determined, the flipping base 52 can drive the battery cell b to the same position each time, so as to improve the accuracy of battery cell b transfer. The battery cell b can be accurately transferred to the top cover a, which improves the assembly accuracy of the battery.

[0144] In addition, when the flip base 52 rotates, the lifting assembly 32 drives the limit switch to descend, so that the top cover a extends out of the mounting port 311 of the limit shell 31, avoiding interference between the flip base 52 or the battery cell b and the limit shell 31, and ensuring the normal assembly of the battery.

[0145] Another embodiment of this application provides a battery production line, including the multifunctional battery fixture described above.
