[0002] During the production and testing process of battery cells, multiple battery cells often need to be stacked so that the film layer on the entire surface of the battery cell is in direct contact with the electrode on the back of another battery cell.

[0057] The battery cell bagging equipment provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0058] like Figure 1 , Figure 6 , Fig.16 and Fig.17As shown, according to some embodiments of the present application, the battery cell bagging equipment includes: a fixing frame 10, a film feeding mechanism 30, a bag sealing mechanism 40 and a film feeding mechanism 50; the fixing frame 10 is provided with a feeding mechanism 20, and the feeding mechanism 20 is used to supply a film 111; the film feeding mechanism 30 is arranged opposite to the feeding mechanism 20, and a transmission channel is provided in the film feeding mechanism 30, and is used to transport the film 111 along a first direction X; the bag sealing mechanism 40 is arranged in the transmission channel, and is used to heat-seal the film 111 in the transmission channel to form a film bag 111a; The sheet mechanism 50 includes a first base 510, a sheet feeding assembly 500 and at least two spaced-apart separation strips 560. The first base 510 is arranged opposite to the transmission channel and is located at the downstream station of the bag sealing mechanism 40. One end of the separation strip 560 is connected to the first base 510, and the other end extends toward the transmission channel and at least partially extends into the film bag 111a to open the bag opening of the film bag 111a. The sheet feeding assembly 500 is movably connected to the first base 510 and is used to feed the battery sheet 120 into the film bag 111a.

[0059] In the embodiment of the present application, the film 111 supplied by the feeding mechanism 20 is transmitted through the transmission channel in the film feeding mechanism 30, and the film 111 is heat-sealed by the bag sealing mechanism 40 provided in the transmission channel to form a plurality of continuous film bags 111a. Then, when the film bags 111a pass through the film feeding mechanism 50, the separation strip 560 in the film feeding mechanism 50 opens the bag mouth of the film bag 111a, and the film feeding assembly 500 is used to heat-seal the film 111a.

[0060] The cell 120 is fed into the film bag 111a to achieve bagging protection for the cell 120, thereby preventing the cell 120 from being scratched on the surface during stacking and transportation. In addition, in the cell bagging equipment of the present application, by integrating the operations of feeding, bag making, and bagging, the automatic bagging protection of the cell can be achieved, which can reduce labor costs.

[0061] It is understandable that if Fig.17 As shown, the battery cell bagging equipment in the embodiment of the present application can be used to pack the battery cells 120 into the film bag 111a. Then, when the battery cells are stacked and stored, the film bag 111a is used to separate two adjacent battery cells 120, so as to prevent the surface of the battery cells 120 from being scratched.

[0062] In specific applications, the battery cell bagging equipment in the embodiment of the present application can be applied to the scenario of battery cells 120. After the battery cells 120 are tested, the battery cell bagging equipment is used to bag the tested battery cells 120, and then the battery cells 120 with the film bags 111a are stored and transferred, which can avoid scratches on the surface of the battery cells 120. Alternatively, it can also be applied to the application scenario of using battery cells 120 to prepare photovoltaic modules. During the preparation process, the battery cell bagging equipment is used to bag and protect the battery cells 120 to avoid scratches during the transportation of the battery cells. Of course, the battery cell bagging equipment in the embodiment of the present application can also be applied to other application scenarios that require stacking and transportation of battery cells 120, and the embodiment of the present application is not limited to this.

[0063] Specifically, Figure 1 As shown, the battery cell bagging equipment includes a fixing frame 10, and the fixing frame 10 can adopt an integrated structure or a split structure. The fixing frame 10 is respectively equipped with a feeding mechanism 20, a film feeding mechanism 30, a bag sealing mechanism 40 and a film feeding mechanism 50. A transmission channel is formed in the film feeding mechanism 30. The film 111 supplied by the feeding mechanism 20 is continuously transported backward through the transmission channel. When passing through the bag sealing mechanism 40, the film 111 is heat-sealed by the bag sealing mechanism 40 to form a film bag 111a with an opening on one side. Then, the film 111 is continuously passed through the bag sealing mechanism 40, and the film 111 can be heat-sealed into a plurality of continuous film bags 111a by the bag sealing mechanism 40, and the film bags 111a are continuously transported backward through the film feeding mechanism 50 by the transmission channel.

[0064] Among them, Figure 6 As shown, the sheet feeding mechanism 50 includes a first base 510, a sheet feeding assembly 500 and at least two spaced-apart separation strips 560. The first base 510 is arranged opposite to the transmission channel and is located at the downstream station of the bag sealing mechanism 40. The sheet feeding assembly 500 is movably connected to the first base 510.

[0065] A first fixing plate 550 is provided at one end of the first base 510 close to the transmission channel, and at least two separation strips 560 are installed on the first fixing plate 550 at intervals along the first direction X. The separation strips 560 extend from the first fixing plate 550 into the transmission channel and at least partially extend into the film bag 111a to open the bag opening of the film bag 111a.

[0066] Furthermore, when the film 111 in the transmission channel passes through the bag sealing mechanism 40, the bag opening of the film bag 111a faces the film feeding mechanism 50, and the bag opening of the film bag 111a is opened by the separation strip 560. The film feeding assembly 500 can move relative to the first base 510 along the second direction Y, and the second direction Y is perpendicular to the first direction X. The film feeding assembly 500 can carry the battery cells and feed the battery cells into the film bag 111a. In this way, through the battery cell bagging equipment of the present application, the bagging operations of the film bag 111a and the bagging operations of the battery cells 120 can be completed at one time, which can not only realize the protection of the battery cells 120, but also realize automatic operation and reduce labor costs.

[0067] Specifically, the film 111 supplied into the transport channel by the feeding mechanism 20 includes two layers, for example Fig.16 As shown, the film 111 can be folded in half. When the film 111 passes through the bag sealing mechanism 40, the bag sealing mechanism 40 heat-seals the film 111 at a certain distance to form a film bag 111a with one end open.

[0068] Among them, at least part of the edge of one side of the film bag 111a near the bag opening is not heat-sealed, that is, along the second direction Y, the length of the heat-sealed part of the film bag 111a is less than the total length of the film bag 111a. In this way, an area for the separation strip 560 to pass through is reserved at the bag opening of the film bag 111a, and then after the film 111 is heat-sealed to form a plurality of continuous film bags 111a, as the film bag 111a is continuously transported in the transport channel, the end of the separation strip 560 can always be located between the two layers of film 111 forming the film bag 111a, so as to open the bag opening of the film bag 111a, so that the cell 120 can be smoothly loaded into the film bag 111a by the cell feeding assembly 500.

[0069] In some embodiments, the material of the film 111 can be polyethylene, polypropylene, etc., so that the cost of raw materials for preparing the film bag 111a can be reduced, and the cost of bagging and protecting the battery cells can be reduced. Of course, the material of the film 111 can also be other materials, which can be flexibly selected according to actual needs and are not limited here.

[0070] In addition, the separation strip 560 can be movably connected to the first fixing plate 550 along the first direction X so as to

[0071] The position of the separation strip 560 can be flexibly adjusted to match the bag opening size of the film bag 111a to meet the usage requirements of different application scenarios.

[0072] Alternatively, if Figure 6As shown, the film feeding assembly 500 includes: a first rotating shaft 520, a first conveyor belt 530 and a first driving member 540. The first rotating shaft 520 is rotatably connected to the two ends of the first base 510 along the second direction Y, and the first conveyor belt 530 is sleeved on the first rotating shaft 520; the first driving member 540 is connected to the first rotating shaft 520, and is used to drive the first rotating shaft 520 to drive the first conveyor belt 530 to move, and to feed the battery cells into the film bag 111a through the first conveyor belt 530.

[0073] In the embodiment of the present application, the sheet feeding assembly 500 adopts a conveyor belt structure, and multiple battery sheets can be placed on the first conveyor belt 530 in sequence. The first driving member 540 drives the first rotating shaft 520 to rotate, and the first rotating shaft 520 drives the first conveyor belt 530 to move, so that the battery sheets are transmitted from the first conveyor belt 530 to the transmission channel to realize automatic bagging operation.

[0074] The first conveyor belt 530 can convey the battery cells along the second direction Y, and the conveyor channel can convey the film bag 111a along the first direction X. The automatic bagging operation of the battery cells 120 can be realized through the cooperation of the first conveyor belt 530 and the conveyor channel.

[0075] Specifically, the first base 510 can be arranged on one side of the transmission channel along the second direction Y, and the first base 510 is provided with a first rotating shaft 520 at both ends along the second direction Y. Among the first rotating shafts 520 arranged at both ends of the first base 510, one can be used as an active rotating shaft, and the first driving member 540 is connected to the active rotating shaft to drive the active rotating shaft to rotate, so as to drive the first transmission belt 530 to move. In addition, the first base 510 is provided with a waist-shaped hole at one end away from the active rotating shaft, and the corresponding first rotating shaft 520 is rotatably connected to the waist-shaped hole, so that the tension of the first transmission belt 530 can be adjusted by adjusting the position of the first rotating shaft 520 in the waist-shaped hole 3101.

[0076] It should be noted that the first driving component 540 may be a servo motor, a stepper motor or other driving components, or other types of driving components, which is not limited in the embodiment of the present application.

[0077] In some embodiments, Figure 1 and Figure 7 As shown, the battery cell bagging device can also be provided with a loading mechanism 90, which is arranged opposite to the feeding mechanism 50, so that the battery cell 120 can be continuously conveyed to the feeding mechanism 50 through the loading mechanism 90. The loading mechanism 90 can adopt a belt transmission mechanism (such as Figure 7 As shown), a robotic arm or other device that can transport the battery

[0078] The structure of the sheet 120 can be flexibly configured according to actual conditions, and the embodiment of the present application does not limit this.

[0079] Alternatively, if Figure 6 As shown, a plurality of protrusions 5301 are disposed on the first conveyor belt 530 , and the plurality of protrusions 5301 are arranged at intervals along the second direction Y, and a storage area for storing battery cells is formed between two adjacent protrusions 5301 .

[0080] In the embodiment of the present application, a plurality of spaced protrusions 5301 are provided on the first conveyor belt 530 to form a storage area between two adjacent protrusions 5301, and the battery cell 120 can be stored in the corresponding storage area. In this way, the protrusions 5301 can limit the position of the battery cell 120, and at the same time, during the process of transferring the battery cell from the first conveyor belt 530 to the film bag 111a in the transmission channel, the protrusions 5301 can also be used to provide thrust for the battery cell, so that the battery cell is easier to be loaded into the film bag 111a.

[0081] Among them, a plurality of spaced-apart protrusions 5301 are provided on the first conveyor belt 530, and the protrusions 5301 protrude from the conveying surface of the first conveyor belt 530. The protrusions 5301 may be a structure integrally formed with the first conveyor belt 530, or may be a structural member separately provided on the first conveyor belt 530, which is not limited in the present application.

[0082] It should be noted that the battery cell 120 in the embodiment of the present application can be a back-contact battery cell, and the electrodes of the back-contact battery cell are all arranged on the back side. When the battery cell 120 is transmitted using the first conveyor belt 530, the entire surface of the battery cell is placed on the first conveyor belt 530 facing upward, thereby reducing the risk of the front side of the battery cell being scratched during the transmission and bagging process.

[0083] In a specific application, the first conveyor belt 530 drives the battery cells to move toward the transmission channel along the second direction Y. When the battery cells move to the end of the first base 510 close to one end of the transmission channel, as the first conveyor belt 530 continues to move, the battery cells will partially detach from the first conveyor belt 530 and enter the film bag 111a. As the first conveyor belt 530 continues to move, the friction force will push the battery cells to transfer into the film bag 111a.

[0084] Furthermore, by providing a protrusion 5301 on the first conveyor belt 530, as the first conveyor belt 530 moves, the protrusion 5301 can apply thrust to the battery cells to continuously push the battery cells into the film bag 111a, thereby reducing the relative sliding between the battery cells and the first conveyor belt 530 and improving the stability of the battery cell bagging.

[0085] Alternatively, if Fig. 9As shown, the battery cell bagging equipment also includes a sheet pushing mechanism 60, which is arranged at the downstream station of the sheet feeding mechanism 50; along the second direction Y, the sheet pushing mechanism 60 is at least partially movable relative to the transmission channel to push all the battery cells into the film bag 111a, wherein the second direction Y is perpendicular to the first direction X.

[0086] It is understandable that, during the process of transferring the battery cell 120 from the feeding mechanism 50 to the transmission channel, the battery cell 120 partially extends into the film bag 111a, and partially protrudes from the film bag 111a. Therefore, by providing the pushing mechanism 60, the pushing mechanism 60 is at least partially moved along the second direction Y to push all the battery cells 120 into the film bag 111a, so as to complete the bagging operation of the battery cells 120.

[0087] Alternatively, if Fig. 9 As shown, the sheet pushing mechanism 60 includes a second base 610, a second driving member 620 and a pushing plate 630; the second base 610 is installed on the fixing frame 10, the second driving member 620 is connected to the second base 610, and the pushing plate 630 is connected to the second driving member 620. The second driving member 620 is used to drive the pushing plate 630 to move along the second direction Y to push all the battery sheets 120 into the film bag 111a.

[0088] Among them, the second driving member 620 can be a linear driving mechanism such as a cylinder or a motor. The second driving member 620 is installed on the fixed frame 10, and the push plate 630 is connected to the output end of the second driving member 620. The push plate 630 is provided with a push piece portion at one end facing the transmission channel. The push piece portion is used to contact the side of the battery cell so that the second driving member 620 drives the push plate 630 to move toward the transmission channel, and the push piece portion of the push plate 630 is used to push the battery cell as a whole into the film bag 111a.

[0089] Alternatively, if Figure 6 and Figure 8 As shown, the battery cell bagging equipment also includes a third base 570 and a clamping assembly 580. The third base 570 is arranged between the film feeding mechanism 50 and the film feeding mechanism 30, and the clamping assembly 580 is arranged at both ends of the third base 570 along the first direction X; the clamping assembly 580 is provided with a roller 5803, and the roller 5803 is used to clamp the battery cell delivered by the film feeding mechanism 50.

[0090] In the embodiment of the present application, a third base 570 is provided between the film feeding mechanism 50 and the film feeding mechanism 30, and a clamping assembly 580 is provided at both ends of the third base 570 in the first direction X. Then, when the battery cell 120 in the first conveyor belt 530 is transferred to the edge of one side close to the transmission channel, the battery cell 120 will extend from the first conveyor belt 530. At this time, the rollers 5803 in the two clamping assemblies 580 are used to clamp and limit the battery cell 120, so as to avoid the problem of position deviation and skewed film jamming during the process of the battery cell 120 being bagged, and ensure the accurate bagging of the battery cell 120.

[0091] Among them, a flexible material layer is provided on the periphery of the roller 5803, and the flexible material layer is in contact with the battery cell so as to play a buffering role between the roller 5803 and the battery cell to prevent the battery cell from being pinched. By way of example, the roller 5803 can be a rubber-coated roller. Of course, the specific setting structure and material of the flexible material layer can be flexibly set according to actual needs, and the embodiments of the present application are not limited here.

[0092] Alternatively, if Figure 6 and Figure 8 As shown, the clamping assembly 580 also includes a third driving member 5801 and a connecting plate 5802. The third driving member 5801 is installed on the third base 570. One end of the connecting plate 5802 is connected to the third driving member 5801. The roller 5803 is rotatably connected to the other end of the connecting plate 5802. The rollers 5803 in the two clamping assemblies 580 are arranged relative to each other to clamp the battery cell 120. The third driving member 5801 is used to drive the connecting plate 5802 to move, so as to drive the roller 5803 to approach or move away from the battery cell.

[0093] In the embodiment of the present application, the third driving member 5801 can drive the connecting plate 5802 and the roller 5803 to move toward the third base 570, and then the position of the roller 5803 can be flexibly adjusted to better meet the clamping requirements of the battery cell.

[0094] Specifically, a plurality of roller holes may be provided at one end of the connecting plate 5802 away from the third driving member 5801. The plurality of roller holes are arranged in sequence and spaced apart along the second direction Y. The roller 5803 is rotatably connected to the roller hole. In specific applications, the roller 5803 may be flexibly adjusted according to the clamping requirements to the corresponding roller hole installed to adapt to the requirements of different usage scenarios.

[0095] It should be noted that the third driving component 5801 can be a driving cylinder, a hydraulic lever, a linear motor or other driving components, and other types of driving components can also be selected, and this embodiment of the present application does not limit this.

[0096] It is understandable that after the battery cell 120 extends from the end of the first conveyor belt 530 close to the conveying channel, it will be clamped and limited by the two rollers 5803. As the first conveyor belt 530 moves, the protrusion 5301 will push the battery cell 120 into the film bag 111a. When the battery cell 120 completely leaves the first conveyor belt 530, one end of the battery cell 120 has entered the film bag 111a, and the other end is clamped between the two rollers 5803.

[0097] At this time, the third driving member 5801 is used to drive the movement of the connecting plate 5802, so that the connecting plate 5802 can drive the roller 5803 to loosen the battery cell 120 and move to the bottom of the battery cell 120, thereby avoiding the battery cell 120, so that the battery cell 120 can be transmitted to the next operating station in the transmission channel along with the film bag 111a.

[0098] In some embodiments, Figure 6 and Figure 8 As shown, the first conveyor belt 530 has a conveying surface, and the moving direction of the connecting plate 5802 forms a preset angle with the conveying surface.

[0099] In the embodiment of the present application, a preset angle is formed between the moving direction of the connecting plate 5802 and the transmission surface of the first conveyor belt 530, that is, a certain inclination angle is formed between the moving direction of the connecting plate 5802 and the transmission surface of the first conveyor belt 530, so that when there is no need to clamp the battery cell 120, the connecting plate 5802 can be driven by the third driving member 5801 to drive the roller 5803 away from the battery cell 120, thereby avoiding interference with the transmission of the battery cell 120.

[0100] Specifically, mounting bevels can be set at both ends of the third base 570, and a preset angle is formed between the mounting bevel and the transmission surface of the first transmission belt 530. The third driving member 5801 is installed on the mounting bevel, and the connecting plate 5802 is connected to the third driving member 5801, so that the third driving member 5801 can drive the connecting plate 5802 to move back and forth along the extension direction of the mounting bevel.

[0101] Among them, the preset angle can be set to be greater than 0° and less than 90°. For example, it can be set to any angle such as 15°, 30°, 45°, 60°, 75°, 80°, or a range between any two angles.

[0102] Alternatively, if Figures 2 to 4As shown, the film feeding mechanism 30 includes a fourth base 310, a second rotating shaft 330, a fourth driving member 340 and a second conveying belt 350; the fourth base 310 is installed on the fixed frame 10, the fourth base 310 is arranged opposite to the feeding mechanism 20, the second rotating shaft 330 is rotatably connected to the two ends of the fourth base 310 along the first direction X, the second conveying belt 350 is sleeved on the second rotating shaft 330 to form a transmission channel, and the fourth driving member 340 is used to drive the second rotating shaft 330 to rotate, so as to drive the second conveying belt 350 to move along the first direction X.

[0103] In the embodiment of the present application, the second rotating shaft 330 can be driven to rotate by the fourth driving member 340 to drive the second conveyor belt 350 to move, and then the second conveyor belt 350 transmits the film 11 to pass through the bag sealing mechanism 40, the film feeding mechanism 50 and the film pushing mechanism 60 in sequence, thereby completing the bag sealing and bagging operations.

[0104] Specifically, the fourth base 310 can be a fixed bracket or a fixed plate. One end of the fourth base 310 is arranged opposite to the feeding mechanism 20, and the other end extends in a direction away from the feeding mechanism 20. Then, mounting holes are respectively provided at both ends of the fourth base 310. The second rotating shaft 330 is rotatably connected to the

[0105] A bearing may also be provided between the second rotating shaft 330 and the hole wall of the mounting hole to reduce the friction resistance during the rotation of the second rotating shaft 330 .

[0106] Furthermore, one of the second rotating shafts 330 disposed at both ends of the fourth base 310 can be used as a driving rotating shaft, so that the fourth driving member 340 is connected to the driving rotating shaft, and then the driving rotating shaft is driven to rotate by the fourth driving member 340, so as to drive the second transmission belt 350 to move. A waist-shaped hole 3101 is provided on the end of the fourth base 310 that is away from the driving rotating shaft, and the corresponding second rotating shaft 330 is rotatably connected in the waist-shaped hole 3101, and then the tension of the second transmission belt 350 can be adjusted by adjusting the position of the second rotating shaft 330 in the waist-shaped hole 3101.

[0107] The fourth driving component 340 may be a servo motor, a stepping motor or other driving components, or other types of driving components, which is not limited in the embodiment of the present application.

[0108] In a specific application, the fourth base 310 is provided with a notch at a position corresponding to the first base 510, so that the end of the first conveyor belt 530 corresponds to the side position of the second conveyor belt 350, and then, when the battery cell 120 is transferred to the conveying channel, as the first conveyor belt 530 continues to move, the battery cell 120 will be transferred from the first conveyor belt 530 to the conveying channel. At this time, the film bag 111a formed by heat sealing is transferred to the corresponding position of the first conveyor belt 530 by the second conveyor belt 350, and the opening of the film bag 111a is facing the first conveyor belt 530. As the first conveyor belt 530 moves, the protrusion 5301 on the first conveyor belt 530 can push the battery cell 120 to at least partially extend into the film bag 111a.

[0109] Alternatively, if Figures 2 to 4 As shown, the film feeding mechanism 30 also includes a support plate 320, the support plate 320 is connected to the fourth base 310, the second conveyor belt 350 covers the support plate 320, a plurality of spaced vacuum grooves 3201 are provided in the support plate 320, a plurality of spaced through holes 3501 are provided in the second conveyor belt 350, at least some of the through holes 3501 are connected to the vacuum grooves 3201, and the vacuum grooves 3201 are used to connect to an external vacuum system to provide negative pressure to the through holes 3501.

[0110] In the embodiment of the present application, the support plate 320 can be used to support the second conveyor belt 350. At the same time, the vacuum groove 3201 in the support plate 320 can provide negative pressure to the through hole 3501 in the second conveyor belt 350, so that the film 111 is adsorbed on the second conveyor belt 350 and moves with the second conveyor belt 350. In this way, in the process of making the film bag 111a from the film 111 and loading the battery cell 120 into the film bag 111a, the second conveyor belt 350 can always be used to adsorb the film 111.

[0111] Adsorption fixation and transmission to the rear end ensure transmission stability.

[0112] Specifically, a support plate 320 is arranged on the fourth base 310, and the second conveyor belt 350 is sleeved on the second rotating shaft 330 and the support plate 320. A plurality of vacuum grooves 3201 are arranged in the support plate 320, and correspondingly, a plurality of through holes 3501 are arranged in the second conveyor belt 350. During the movement of the second conveyor belt 350 relative to the support plate 320, some of the through holes 3501 always remain connected to the vacuum grooves 3201, so that an external vacuum system can be used to provide negative pressure to the through holes 3501 through the vacuum grooves 3201, so that the film 111 can be adsorbed on the second conveyor belt 350.

[0113] In some embodiments, the vacuum grooves 3201 provided in the support plate 320 can be configured as strip-shaped grooves, and several strip-shaped grooves are respectively connected to the external vacuum system. The extension directions of the several strip-shaped grooves can be parallel to the transmission direction of the second conveyor belt 350, or the extension directions of the several strip-shaped grooves intersect with the transmission direction of the second conveyor belt 350. It is sufficient as long as it is ensured that during the movement of the second conveyor belt 350 relative to the support plate 320, some through holes 3501 can always remain connected to the vacuum grooves 3201.

[0114] In a specific application, when the film bag 111a in the transmission channel moves to the corresponding position of the film feeding mechanism 50, the lower film 111 of the two layers of film 111 forming the film bag 111a is adsorbed on the second conveyor belt 350, and the separation strip 560 extends into the film bag 111a to prop up the upper film 111, so that the bag mouth of the film bag 111a can be opened, which facilitates the smooth loading of the battery cell 120 into the film bag 111a.

[0115] Alternatively, if Fig.10 and Fig.11 As shown, the bag sealing mechanism 40 includes: a fifth base 410, a fifth driving member 420 and a sealing assembly 430; one end of the fifth base 410 is installed on the fixed frame 10, and the other end extends to the top of the transmission channel; the fifth driving member 420 is installed on the other end of the fifth base 410, and the sealing assembly 430 is connected to the fifth driving member 420, and the sealing assembly 430 is provided with a sealing portion on the side facing the transmission channel; the fifth driving member 420 is used to drive the sealing assembly 430 to move so as to heat-seal the film 111 in the transmission channel through the sealing portion.

[0116] In an embodiment of the present application, a bag sealing mechanism 40 is provided in the transmission channel, and the fifth driving member 420 in the bag sealing mechanism 40 can be used to drive the sealing assembly 430 to move relative to the transmission channel, and then the film 111 in the transmission channel is heat-sealed by the sealing portion of the sealing assembly 430, thereby preparing a film bag 111a.

[0117] It can be understood that the film 111 supplied by the feeding mechanism 20 is transmitted in the transmission channel, and the bag sealing mechanism 40 is used to perform heat sealing operations at intervals to heat-seal the film 111 into a plurality of interconnected film bags 111a, and then the film feeding mechanism 50 is used to load at least one battery cell 120 into each film bag 111a.

[0118] In some embodiments, Fig.10As shown, the sealing assembly 430 includes a mounting plate 4301, a guide rod 4302 and a sealing member 4303. The mounting plate 4301 is connected to the fifth driving member 420. The other end of the fifth base 410 is provided with a guide hole. One end of the guide rod 4302 is inserted into the guide hole. The other end of the guide rod 4302 is fixedly connected to the mounting plate 4301. The sealing member 4303 is provided on the side of the mounting plate 4301 facing the transmission channel to form the sealing portion. The fifth driving member 420 can drive the mounting plate 4301 to drive the sealing member 4303 to approach or move away from the transmission channel, and then the sealing member 4303 can be used to heat-seal the film 111 in the transmission channel to form a film bag 111a.

[0119] Specifically, the welding seal 4303 may include a welding seal block and a heating rod, wherein the welding seal block is connected to the side of the mounting plate 4301 facing the transmission channel, and the heating rod is embedded in the welding seal block, and the heating rod is used to heat the welding seal block, and then the welding seal block heat-seals the film 111. The welding seal block may be a heat-conducting structural member such as a copper block.

[0120] The number of guide rods 4302 can be multiple, and the multiple guide rods 4302 can guide the movement of the mounting plate 4301, thereby improving the stability of the movement of the mounting plate 4301. In addition, a piston bearing can be arranged in the guide hole, and the guide rod 4302 is inserted into the piston bearing, thereby reducing the friction resistance of the guide rod 4302 during the reciprocating movement.

[0121] Alternatively, if Fig.10 As shown, the bag sealing mechanism 40 also includes: a separation plate 440 and a connecting rod 450; the separation plate 440 is arranged on the side of the sealing and welding assembly 430 facing the transmission channel, one end of the connecting rod 450 is movably connected to the sealing and welding assembly 430, and the other end of the connecting rod 450 is connected to the separation plate 440; the separation plate 440 is provided with a matching hole at a position corresponding to the sealing part, and the sealing part can move relative to the matching hole.

[0122] During the heat sealing operation, the fifth driving member 420 drives the sealing assembly 430 to move toward the transmission channel, and the sealing portion of the sealing assembly 430 passes through the matching hole in the separation plate 440 to contact the film 111, thereby achieving heat sealing of the film 111. After the heat sealing is completed, the fifth driving member 420 drives the sealing assembly 430 to move in a direction away from the transmission channel. At this time, the separation plate 440 moves toward the transmission channel under the action of gravity.

[0123] The film bag 111a slides downward to separate from the sealing portion of the sealing assembly 430, thereby preventing the sealing assembly 430 from sticking to the film bag 111a.

[0124] The structure of the matching hole is matched with the structure of the sealing part in the sealing assembly 430. Specifically, the structure of the matching hole is matched with the structure of the sealing block, and the sealing block can move freely in the matching hole.

[0125] Alternatively, if Fig.13 and Fig.14 As shown, the feeding mechanism 20 includes a feeding assembly 210 and a tensioning assembly 220. The feeding assembly 210 is connected to the fixing frame 10. The feeding assembly 210 is used to fix the material roll 110 (such as Fig.16 As shown in the figure, the feeding assembly 210 is at least partially rotatable relative to the fixed frame 10 to supply the film 111 through the material roll 110; the tensioning assembly 220 is arranged between the feeding assembly 210 and the film feeding mechanism 30, and is used to tension the film 111.

[0126] In the embodiment of the present application, a feeding assembly 210 is provided in the feeding mechanism 20, and the feeding assembly 210 can be used to fix the material roll 110 wound with the film 111, and the feeding assembly 210 can at least partially rotate relative to the fixing frame 10, so that the film 111 can be continuously supplied to the transmission channel. At the same time, the tensioning assembly 220 is used to tension the film 111 to prevent the film 111 from wrinkling, overlapping, and other problems.

[0127] The number of the feeding components 210 can be one or more. When there are more than one feeding components 210, when the film 111 on the material roll 110 in one feeding component 210 is used up, the material roll 110 in another feeding component 210 can be quickly replaced, which is convenient for actual operation and can save operation time.

[0128] Alternatively, if Fig.13 and Fig.14 As shown, the feeding assembly 210 includes a sixth driving member 2101 and a reel 2102; the reel 2102 is rotatably connected to the fixed frame 10, and the reel 2102 is used to be inserted into the material roll 110; the sixth driving member 2101 is connected to the reel 2102, and the reel 2102 can be driven to rotate by the sixth driving member 2101, so that the material roll 110 continuously supplies the film 111 to the transmission channel.

[0129] Specifically, the feeding assembly 210 may further include a bearing base and a locking sleeve, wherein the bearing base is mounted on the fixing frame 10, one end of the reel 2102 passes through the bearing base and is connected to the sixth driving member 2101, the material roll 110 is passed through the reel 2102, the locking sleeve is sleeved on the reel 2102, and the locking sleeve cooperates with the bearing base to clamp and fix the material roll 110. When the material roll 110 needs to be replaced, the operation can be completed by removing the locking sleeve.

[0130] Alternatively, if Fig.15As shown, the tensioning assembly 220 includes: a second fixed plate 2201, a tensioning wheel 2202 and an auxiliary wheel 2203. The second fixed plate 2201 is installed on the fixed frame 10. The auxiliary wheel 2203 and the tensioning wheel 2202 are both rotatably connected to the second fixed plate 2201. The auxiliary wheel 2203 is arranged on the opposite sides of the tensioning wheel 2202. The film 111 output from the material roll 110 passes through the auxiliary wheel 2203 and the tensioning wheel 2202 in sequence.

[0131] In the embodiment of the present application, by installing a tensioning wheel 2202 and an auxiliary wheel 2203 on the second fixed plate 2201, the film 111 passes through the auxiliary wheel 2203 and the tensioning wheel 2202 in sequence, and then by adjusting the height difference between the tensioning wheel 2202 and the auxiliary wheel 2203, the tensioning degree of the film 111 can be adjusted.

[0132] Alternatively, if Fig.15 As shown, the tensioning assembly 220 also includes a pressure measuring member 2204 and a control member (not shown in the figure). The pressure measuring member 2204 is arranged between the second fixed plate 2201 and the tensioning wheel 2202, and is used to detect the tensioning force exerted on the tensioning wheel 2202; the control member is electrically connected to the pressure measuring member 2204 and the sixth driving member 2101, respectively, and is used to adjust the operation of the sixth driving member 2101 based on the tensioning force.

[0133] In the embodiment of the present application, a pressure measuring piece 2204 is arranged between the fixed plate and the tensioning wheel 2202. When the film 111 passes through the auxiliary wheel 2203 and the tensioning wheel 2202, as the tensioning degree of the film 111 changes, the tensioning force of the film 111 on the tensioning wheel 2202 will also change. Then, the tensioning force exerted on the tensioning wheel 2202 is detected by the pressure measuring piece 2204, so that the control component can flexibly adjust the operation of the sixth driving component 2101 according to the size of the tensioning force, thereby adjusting the tensioning degree of the film 111.

[0134] When the detected tensioning force is too large, the sixth driving member 2101 is controlled by the control member to reduce the rotation speed. When the measured tensioning force is too small, the sixth driving member 2101 can be controlled by the control member to increase the rotation speed, thereby adjusting the tension of the film 111.

[0135] Alternatively, if Fig.12 As shown, the battery cell bagging equipment further includes a film cutting mechanism 70 , which is arranged opposite to the transmission channel and located at the downstream station of the film feeding mechanism 50 , and is used to cut the film bag 111 a containing the battery cells 120 .

After the film feeding mechanism 50 loads the battery cell 120 into the film bag 111a, the film cutting mechanism 70 can be used to cut the film bag 111a in the transmission channel to obtain a single film bag 111a containing the battery cell 120, thereby facilitating the transfer of the bagged battery cell 120.

[0137] Alternatively, if Fig.12 As shown, the film cutting mechanism 70 includes a sixth base (not shown in the figure), an upper cutter assembly 710 and a lower cutter assembly 720; the sixth base is arranged at one end of the film feeding mechanism 30 away from the feeding mechanism 20, the upper cutter assembly 710 is installed on the sixth base, and the lower cutter assembly 720 is installed on the fixed frame 10, the upper cutter assembly 710 and the lower cutter assembly 720 are arranged opposite to each other, and the upper cutter assembly 710 and the lower cutter assembly 720 can move relatively to each other to cut the film bag 111a containing the battery cell 120.

[0138] In the embodiment of the present application, a sixth base is provided at one end of the film feeding mechanism 30 away from the feeding mechanism 20, an upper cutter assembly 710 is installed on the sixth base, and a lower cutter assembly 720 is correspondingly installed on the fixed frame 10. By utilizing the cooperation of the upper cutter assembly 710 and the lower cutter assembly 720, the film bag 111a in the transmission channel can be cut.

[0139] Specifically, Fig.12 As shown, the sixth base is connected to the fixed frame 10, the upper cutter assembly 710 includes an upper driving member 7101, an upper cutter fixing block 7102 and an upper cutter 7103, the upper driving member 7101 is installed on the sixth base, the upper cutter fixing block 7102 is connected to the upper driving member 7101, and the upper cutter 7103 is installed on the side of the upper cutter fixing block 7102 facing the lower cutter assembly 720.

[0140] Correspondingly, the lower cutter assembly 720 includes a lower driving member 7201, a lower cutter fixing block 7202 and a lower cutter 7203. The lower driving member 7201 is mounted on the fixing frame 10, the lower cutter fixing block 7202 is connected to the lower cutter fixing block 7202, and the lower cutter 7203 is mounted on one side of the lower cutter fixing block 7202 facing the upper cutter 7103 assembly. The upper cutter 7103 and the lower cutter 7203 are opposite to each other.

[0141] During the cutting operation, the upper driving member 7101 drives the upper cutter fixing block 7102 to drive the upper cutter 7103 to move downward. At the same time, the lower driving member 7201 drives the lower cutter fixing block 7202 to drive the lower cutter 7203 to move upward, and then the upper cutter 7103 and the lower cutter 7203 cooperate to cut the film bag 111a.

[0142] In addition, a film separating plate 7104 can be further provided on the upper cutter fixing block 7102. The film separating plate 7104 is arranged on the side of the upper cutter fixing block 7102 away from the upper driving member 7101. The film separating plate 7104 is movably connected to the upper cutter fixing block 7102. The film separating plate 7104 is provided with a guide hole at a position corresponding to the upper cutter 7103. The upper cutter 7103 can move relative to the guide hole. The film separating plate 7104 can be used to push the film bag 111a away from the cutter after cutting is completed, so as to avoid the cutter sticking to the film bag 111a.

[0143] Alternatively, if Figure 1 , Figure 2 and Figure 5 As shown, the battery cell bagging equipment further includes: a material unloading mechanism 80, which is arranged on the side of the film cutting mechanism 70 away from the film feeding mechanism 30, and is used to transport the cut film bags 111a containing the battery cells 120.

[0144] In the embodiment of the present application, a feeding mechanism 80 is provided on the side of the film cutting mechanism 70 away from the film feeding mechanism 30 so that the feeding mechanism 80 can be used to feed a single film bag 111a containing battery cells 120 cut by the film cutting mechanism 70, thereby facilitating the transfer of the bagged battery cells 120.

[0145] It should be noted that the structure of the unloading mechanism 80 can refer to the structural setting of the film feeding mechanism, and the embodiments of the present application will not be repeated here.

[0146] In addition, the vacuum groove of the support plate 320 in the unloading mechanism 80 can be set at an end close to the film cutting mechanism 70, and the vacuum groove may not be set at the end of the support plate 320 in the unloading mechanism 80 away from the film cutting mechanism 70, so that when the film bag 111a containing the battery cells 120 is transported to a position in the unloading mechanism 80 away from the film cutting mechanism 70, the adsorption effect between the film bag 111a and the conveyor belt is released, thereby facilitating the removal of the film bag 111a.

[0147] Optionally, the embodiment of the present application further provides a battery cell bagging method, which is applied to the battery cell bagging device in the above embodiment, comprising:

[0148] In some embodiments, the specific steps of performing battery packing operation using the battery pack packing equipment in the embodiments of the present application are as follows:

[0149] First, the material roll 110 is installed and fixed on the reel 2102, so that the end of the film 111 on the material roll 110 passes through the tensioning wheel 2202 and the auxiliary wheel 2203 in the tensioning assembly 220 in turn, and extends to the second conveyor belt 350 in the film feeding mechanism 30, and the film 111 is adsorbed and fixed on the second conveyor belt 350 by using vacuum adsorption.

[0150] Then, the fourth driving member 340 drives the second conveyor belt 350 to move the film 111. When the film 111 moves through the corresponding position of the bag sealing mechanism 40, the fifth driving member 420 drives the sealing assembly 430 to heat-seal the film 111 to form a continuous film bag 111a. The film bag 111a continues to move along with the second conveyor belt 350. When it moves to the corresponding position of the film feeding mechanism 50, the first driving member 540 drives the first conveyor belt 530 to move, and the first conveyor belt 530 drives the battery cell 120 to move.
