With such a setting, the battery cell pre-stacking device 2, the aggregate transportation device, the aggregate moving device 5, the belt feeding and conveying device, the belt sleeving device 8, and the finished product conveying device with different functional roles are integrated on the machine table 1. The battery cells and the belts move from their respective production lines and finally reach the material receiving station 9. On one production line, the belt feeding and conveying device successively conveys the belts to the material receiving station 9. At the same time, on the other production line, the battery cell pre-stacking device arranges multiple battery cells into a battery cell aggregate, and then the aggregate transportation device continues to drive the battery cell aggregate to the aggregate moving device 5. The aggregate moving device 5 clamps the battery cell aggregate and reaches the material receiving station 9. At the material receiving station 9, the belt sleeving device 8 sleevs the belt around the battery cell aggregate clamped by the aggregate moving device 5 to form a battery cell module. Finally, the aggregate moving device 5 places the battery cell module on the finished product conveying device, and the finished product conveying device conveys the battery cell module away, completing the entire assembly process. Moreover, the cooperation relationship between the devices is close, the process connection is smooth, no manual intervention is required, and the operation is highly efficient, solving the problems in the prior art that the workstations for assembling battery cell modules are independent and scattered, the connection between each process cannot be smoothly achieved, the degree of automation is low, and the assembly efficiency of battery cell modules is low.

[0069] In a preferred embodiment, a collection transport device is provided to drive the battery cells to move along the first straight line direction, the battery cell pre-stacking device 2 can push multiple battery cells onto the collection transport device and arrange the battery cells along the first straight line direction; the collection moving device 5 can drive the battery cell collection to move along the second straight line direction; the endless belt feeding and conveying device can drive the endless belt along the second straight line direction and move toward the battery cell collection; wherein, the first straight line direction and the second straight line direction are perpendicular to each other, that is, the battery cells and the endless belt enter the battery cell module production line from two positions respectively, and gradually approach each other under the action of each device, and arrive at the material receiving station 9 to complete the final socketing. With such a configuration, each device is arranged in an orderly and reasonable manner, the overall layout of the battery cell module production line is optimized, the footprint is small, and it is conducive to the maximum cooperation between each device, and the assembly efficiency of the battery cell module production line is optimized.

[0070] Furthermore, the endless belt feeding and conveying device includes an endless belt feeding device 6 and an endless belt conveying device 7. The endless belt feeding device 6 can output the endless belts one by one downwards, and the endless belt conveying device 7 receives the endless belts from the endless belt feeding device 6 and conveys the endless belts along the second straight line direction. In this arrangement, the endless belt feeding device 6 utilizes the longitudinal space, and the endless belt conveying device 7 utilizes the lateral space. In the process of gradually transporting the endless belt, the endless belt is regularly conveyed to the receiving station 9, further optimizing the overall layout of the battery cell module production line, reducing the floor space, and further optimizing the assembly efficiency of the battery cell module production line.

[0071] In another preferred embodiment, the finished product conveying device includes a first conveyor line mechanism 10 disposed between the aggregate moving device 5 and the belt device 8. The first conveyor line mechanism 10 can receive the battery cell module clamped and placed down by the aggregate moving device 5, and convey the battery cell module along a third straight line direction; wherein the third straight line direction is parallel to the first straight line direction. In this way, the first conveyor line mechanism 10 that needs to occupy a certain length of space is arranged in parallel with the battery cell pre-stacking device 2 that also occupies a certain length of space. By utilizing the return action of the aggregate moving device 5, the battery cell module is placed in a space on the return path, making full use of the space on the machine 1, and further optimizing the overall layout of the battery cell module production line.

[0072] Moreover, the finished product conveying device further includes an inspection station 13, a second conveyor line mechanism 11, a third conveyor line mechanism 12, and a transfer mechanism. Among them, the inspection station 13 is used to place the battery cell modules to be inspected; the second conveyor line mechanism 11 is used to receive and transport the qualified battery cell modules in the fourth linear direction; the third conveyor line mechanism 12 is used to receive and transport the unqualified battery cell modules in the fifth linear direction; the transfer mechanism can move the battery cell modules on the first conveyor line mechanism 10 to the inspection station 13, and move the battery cell modules at the inspection station 13 to the second conveyor line mechanism 11 or the third conveyor line mechanism 12; the fourth linear direction and the fifth linear direction are perpendicular to each other. In this way, the quality inspection of the originally independently existing battery cell modules is combined with the structure of the battery cell module production line, realizing the completion of the inspection on the battery cell module production line, and then separating and transporting the qualified and unqualified battery cell modules, which is convenient for subsequent processing, helps to improve the quality inspection efficiency, and contributes to assisting in optimizing the entire battery production process.

[0073] It should be noted that the first conveyor line mechanism 10, the second conveyor line mechanism 11, and the third conveyor line mechanism 12 can be set as common conveyor belt structures or conveyor roller structures in the prior art; the transfer mechanism can be set as a manipulator or two cylinders. One cylinder can push the battery cell modules on the first conveyor line mechanism 10 to the inspection station 13 and push the battery cell modules at the inspection station 13 to the second conveyor line mechanism 11, and the other cylinder can push the battery cell modules at the inspection station 13 to the third conveyor line mechanism 12.

[0074] In a specific embodiment, a material receiving station 9 is provided, including a platform 901, a side block 902, a front block 903, a side power assembly 904, and a front power assembly, wherein the platform 901 provides a placement position for the battery cell assembly clamped by the assembly moving device 5, and the area size is smaller than the bottom size of the battery cell assembly; two side blocks 902 are provided and are arranged relative to the platform 901, capable of receiving the endless belt and positioning the edge of the endless belt parallel to the moving direction; the front block 903 is arranged relative to the platform 901 and the endless belt feeding and conveying device, capable of positioning the edge of the endless belt perpendicular to the moving direction; the side power assembly 904 can drive the relatively arranged side blocks 902 to approach and move away from each other, and the front power assembly can drive the positive block 903 to move up and down. With such arrangement, the endless belt, driven by the endless belt feeding and conveying device, moves along the side block 902 until it is located between the two side block 902, or in other words, the two side block 902 lift the endless belt, and the positive block 903 prevents the endless belt from leaving the material receiving station 9 along the entry direction. When the belt wrapping device 8 takes away the endless belt on the material receiving station 9, the side power assembly 904 drives the side block 902 to move away from each other, and the positive power assembly drives the positive block 903 to move downward, and the battery cell assembly clamped by the assembly moving device 5 is placed on the platform 901, and the belt wrapping device 8 continues to move to wrap the endless belt around the battery cell assembly. Both the side power assembly 904 and the positive power assembly can be set as cylinders, hydraulic cylinders or other linear actuators.

[0075] In a preferred embodiment, the battery cell module production line also includes a shaping device arranged between the battery cell pre-stacking device and the assembly transportation device, and the shaping device can align the individual battery cells of the battery cell assembly from the battery cell pre-stacking device, further ensuring that the battery cell assembly is regular in shape before arriving at the material receiving station and performing the ring belting process.

[0076] Furthermore, if Figure 6 As shown, the shaping device 4 can be specifically configured to include two slats 401 arranged opposite to each other, two power cylinders 402 that respectively drive the two slats 401 to move closer to and away from each other, a guide seat 403 fixedly connected to the machine table 1, and a guide pin 404 fixedly connected to the slat 401 and movably connected to the guide seat 403, and the moving direction of the slat 401 is perpendicular to the first straight line direction, and the slide is located at a lower position between the two slats 401.

[0077] In a specific embodiment, Figure 5As shown in the figure, the annular belt feeding device 6 is provided, which includes a material storage structure 601, a material discharging mechanism 602, and a material distributing mechanism 603. The material storage structure 601 includes a first area and a second area where the annular belts can be arranged and placed. The material discharging mechanism 602 has a first state that hinders the displacement of the annular belts in the first area in the feeding direction, and a second state that enables the annular belts in the first area to leave the material storage structure 601 to achieve feeding. The material distributing mechanism 603 has a third state that limits the annular belts in the second area on the material storage structure 601, and a fourth state that enables the annular belts in the second area to move and enter the first area. Among them, the switching from the first state to the second state follows the switching from the fourth state to the third state, and the switching from the third state to the fourth state follows the switching from the second state to the first state. With such a setting, a large number of annular belts are placed on the material storage structure 601 at one time, and the annular belts are distributed in the first area and the second area. When annular belt feeding is required, first, the material discharging mechanism 602 is in the first state, and then the material distributing structure is in the fourth state to ensure that there are annular belts in the first area. Then, the material distributing structure is in the third state, and the annular belts in the second area are positioned. Next, the material discharging mechanism 602 is in the second state to allow the annular belts in the first area to leave along the feeding direction, completing the annular belt feeding. By repeating the above process, the annular belts can be fed in sequence, and the longitudinal space is used to preprocess the annular belts, improving the automation degree from the aspect of annular belt feeding and solving the problems of low automation degree in the steel belt feeding process during the assembly of the battery cell module in the prior art and low assembly efficiency of the battery cell module.

[0078] In a preferred embodiment, the annular belt feeding device 6 is further provided with a buffer mechanism 604. The material storage structure 601 further includes a third area where the annular belts can be arranged and placed. The buffer mechanism 604 has a fifth state that limits the annular belts in the third area in the third area and a sixth state that enables the annular belts in the third area to move and enter the second area. With such a setting, the third area can relatively independently pre-cache some annular belts, and when the annular belts in the third area do not need to enter the second area, it will not interfere with the positions of the annular belts in the second area and the first area, so that the operator can put the annular belts into the material storage structure 601 irregularly and in an indefinite quantity, further reducing the degree of manual participation.

[0079] Preferably, there are two symmetric buffer mechanisms 604, two symmetric material distributing mechanisms 603, and two symmetric material discharging mechanisms 602 respectively. The two buffer mechanisms 604 act simultaneously, the two material distributing mechanisms 603 act simultaneously, and the two material discharging mechanisms 602 act simultaneously.

[0080] In a specific embodiment, the storage structure 601 is provided to include a frame body, which can fit with the inner part or the whole of the endless belt. The first area, the second area, and the third area are the peripheral surface areas of the frame body, and the first area is continuous with the second area. The endless belt can move freely on the frame body. More specifically, the first area is the peripheral surface area horizontally corresponding to the frame body between the highest point of the first pin body and the lower edge of the pressing block 6031; the second area is the peripheral surface area horizontally corresponding to the frame body between the lower edge of the pressing block 6031 and the lower edge of the second pin body 6041; the third area is the peripheral surface area horizontally corresponding to the frame body above the upper edge of the second pin body 6041.

[0081] Furthermore, a guiding body 605 is provided at the end of the frame body. The cross-section of the guiding body 605 gradually expands along the moving direction of the endless belt on the frame body, so that the endless belt can be sleeved around the frame body through the guiding body 605. In other words, the guiding body 605 is in the shape of a frustum of a pyramid. With such a setting, it is convenient for the endless belt to be quickly sleeved on the frame body, optimizing the operation speed.

[0082] In addition, it is preferably that the frame body is vertically arranged, the guiding body 605 is located at the top of the frame body, the third area is above the second area, the second area is above the first area, and the buffer mechanism 604, the material distribution mechanism 603, and the material discharging mechanism 602 are arranged on the machine table 1 from top to bottom. With such a setting, the endless belt freely moves downward on the frame body under the action of gravity, and there is no need for other power to push the endless belt to move along the preset direction.

[0083] More specifically, it is preferably set that the first area accommodates one endless belt, that is, the single feeding of the endless belt is accurately realized, and the number of the second area and the third area is set according to the situation, and about ten can be selected.

[0084] In a specific embodiment, the material discharging mechanism 602 is provided to include a first pin body and a seventh power assembly for driving the first pin body to insert into and leave the storage structure 601. A pin hole matching with the first pin body is provided on the storage structure 601; wherein, when the material discharging mechanism 602 is in the first state, the first pin body inserts into the storage structure 601 and is located below the first area; when the material discharging mechanism 602 is in the second state, the first pin body leaves the storage structure 601 and the endless belt in the first area drops. With such a setting, the switching between the two states of the material discharging mechanism 602 is completed by the reciprocating first pin body, and the limit is realized by the physical blocking effect of the first pin body, which is stable and reliable. The seventh power assembly can be specifically set as a cylinder, a hydraulic cylinder or other linear actuators.

[0085] In a specific embodiment, the material distribution mechanism 603 is provided to include a pressing block 6031 and an eighth power component 6032 for driving the pressing block 6031 to press against and leave the storage structure 601. The lower edge of the pressing block 6031 is located at the lower edge of the second area, ensuring that it can press the lowermost annular belt in the second area without pressing the annular belt in the first area. When the material distribution mechanism 603 is in the third state, the pressing block 6031 presses the annular belt in the second area against the storage structure 601. When the material distribution mechanism 603 is in the fourth state, the pressing block 6031 leaves the storage structure 601 and the annular belt in the second area is released and moves downward. With such a setting, the annular belt in the second area is limited by the pressing action of the pressing block 6031, which is suitable for the case where the first area and the second area are coherent. The eighth power component 6032 can be specifically set as a cylinder, a hydraulic cylinder or other linear actuators.

[0086] In a specific embodiment, the buffer mechanism 604 is provided to include a second pin body 6041 and a ninth power component 6042 for driving the second pin body 6041 to insert into and leave the storage structure 601. The storage structure 601 is provided with a pin hole that cooperates with the second pin body 6041. When the buffer mechanism 604 is in the fifth state, the second pin body 6041 inserts into the storage structure 601 and is located below the third area. When the buffer mechanism 604 is in the sixth state, the second pin body 6041 leaves the storage structure 601 and the annular belt in the third area is released and moves downward. With such a setting, the switching between the two states of the feeding mechanism 602 is completed by the reciprocating second pin body 6041, and the limit is achieved by the physical blocking action of the second pin body 6041, which is stable and reliable. The ninth power component 6042 can be specifically set as a cylinder, a hydraulic cylinder or other linear actuators.

[0087] In addition, the buffer mechanism 604 in the fifth state and the feeding mechanism 602 in the first state can both be connected to the storage structure 601 and restrict the storage structure 601 from moving in the vertical direction, and the storage structure 601 is always connected to at least one of the feeding mechanism 602 and the buffer mechanism 604. With such a setting, there are no connection structures above and below the storage structure 601, and the storage structure 601 can be suspended in the longitudinal space. The annular belt can be freely sleeved on the top of the storage structure 601, and the annular belt can smoothly fall off at the bottom of the storage structure 601.

[0088] More specifically, the frame body is provided to include a frame border and a support plate. Among them, the frame border includes at least four bars that are all fixedly connected to the guide body and are parallel to each other. The bars have an arc-shaped surface to fit the inner angle of the annular belt. The support plate is fixedly connected between two adjacent bars and is provided with a first pin hole opposite to the first pin body for the first pin body to fit and insert, and a second pin hole opposite to the second pin body 6041 for the second pin body 6041 to fit and insert.

[0089] In a specific embodiment, asFigure 4 As shown in Figure 4 , the endless belt conveying device 7 includes a conveying mechanism 701 for conveying the endless belt from the starting end to the ending end, and a material transferring mechanism 702 capable of moving the endless belt at the ending end to the material receiving station 9. The material receiving station 9 is arranged close to the ending end. With such an arrangement, the conveying mechanism 701 sequentially conveys a plurality of endless belts from the starting end to the ending end, and the material transferring mechanism 702 moves the endless belt at the ending end to the material receiving station 9, so as to finally position the target endless belt at a definite station, facilitating the tape sleeving device 8 to accurately pick up the endless belt, contributing to the smooth progress of the tape sleeving operation, improving the automation degree from the aspect of endless belt feeding and transportation, and solving the problems of low automation degree in the steel belt feeding process during the assembly of the battery cell module and low assembly efficiency of the battery cell module in the prior art.

[0090] Specifically, the conveying mechanism 701 can be specifically arranged as a conveyor belt or a conveying roller.

[0091] In a preferred embodiment, the endless belt feeding and conveying device is further provided with a material blocking mechanism 703 arranged on the conveying mechanism 701, and the material blocking mechanism 703 can block the endless belt from moving to the ending end. With such an arrangement, the material transferring mechanism 702 is not interfered by the endless belts other than the target endless belt each time it operates, ensuring that the endless belts reach the material receiving station 9 in sequence and orderly.

[0092] Specifically, the material blocking mechanism 703 is provided with a belt blocking strip and a cylinder for driving the belt blocking strip to reciprocate up and down. When the belt blocking strip rises, it blocks in front of the next endless belt of the endless belt at the ending end, hindering its movement driven by the conveying mechanism 701. When the belt blocking strip descends, the endless belt moves normally.

[0093] In addition, in order to facilitate the smooth entry of the endless belt into the material receiving station 9, one end of the side baffle 902 close to the ending end of the conveying mechanism 701 is provided with a guide angle, so that the space between the two side baffles 902 gradually expands from the inside to the outside, that is, the side baffles 902 are in an outward-expanded shape.

[0094] In a preferred embodiment, side plates 704 are arranged on both opposite sides of the conveying mechanism 701. The side plates 704 limit the endless belt on the conveying mechanism 701, and the endless belt moves under the guidance of the side plates 704. In this way, not only can the endless belt be prevented from accidentally falling from both sides of the conveying mechanism 701, but also the endless belt can be limited at the set position, facilitating the material transferring mechanism 702 to perform the movement action on the endless belt.

[0095] In another specific embodiment, the material transfer mechanism 702 is arranged above the conveyor mechanism 701 and includes a fixed push plate 7021, a horizontal power assembly 7023, and a movable push plate 7022. Among them, the lower edge position of the fixed push plate 7021 is higher than the upper edge of the endless belt. The horizontal power assembly 7023 drives the fixed push plate 7021 to reciprocate along the moving direction of the endless belt. The movable push plate 7022 is hinged to the side of the fixed push plate 7021 away from the horizontal power assembly 7023 with the horizontal direction as the axis, and the lower edge position is lower than the upper edge of the endless belt. When the fixed push plate 7021 moves towards the material receiving station 9, the movable push plate 7022 pushes the end endless belt to the material receiving station 9 under the limiting action of the fixed push plate 7021. When the fixed push plate 7021 moves away from the material receiving station 9, the movable push plate 7022 can rotate upward under the blocking action of the endless belt and slide over the upper edge of the endless belt. With such a setting, the height positions of the fixed push plate 7021 and the movable push plate 7022 are fixed, and the structural characteristics of the movable push plate 7022 are skillfully utilized. It cannot rotate when pushing forward, so as to exert a rigid thrust on the endless belt, and deflects with the obstruction of the endless belt when retracting backward, and can be smoothly retracted without pushing the endless belt in the reverse direction. The horizontal power assembly 7023 can be specifically set as a cylinder, a hydraulic cylinder or other linear actuators.

[0096] In a specific embodiment, as Figure 7 shown, the battery cell pre-stacking device 2 is provided, which includes a battery cell input mechanism 211, a pushing mechanism, and a battery cell output mechanism. Among them, the battery cell input mechanism 211 can place and transport a plurality of battery cells. The pushing mechanism can push a plurality of battery cells on the battery cell input mechanism 211 to translate in sequence to leave the battery cell input mechanism 211. The battery cell output mechanism can receive the battery cells from the battery cell input mechanism 211 and supply the battery cells to be arranged in a battery cell aggregate along the moving direction. With such a setting, a plurality of standing battery cells are placed at intervals on the battery cell input mechanism 211 and can be arranged in one row or two rows along the transportation direction. Under the transportation action of the battery cell input mechanism 211, the battery cells gradually move closer to the pushing mechanism. Then, under the action of the pushing mechanism, one or two parallel battery cells are translated and pushed onto the battery cell output mechanism. The battery cells located behind will be sequentially attached behind the previous battery cell that has already been on the battery cell output mechanism. In this way, when the preset number of battery cells accumulates on the battery cell output mechanism, they will be arranged into a battery cell aggregate. The entire arrangement process is completed by a coherent translation and pushing action. Compared with the single way of grasping and listing battery cells, the working efficiency is improved, and the problem that the working efficiency of the process of arranging a plurality of battery cells into a battery cell aggregate in the prior art is low, thereby resulting in low assembly efficiency of the battery cell module is solved.

[0097] It should be noted that the stroke of the driving mechanism for driving the battery cell to move is fixed, and the position that the battery cell can reach under the driving action of the driving mechanism is also fixed, that is, the subsequent battery cells will fill the position in front of the previous battery cell. The battery cell input mechanism 211 can be specifically set as a conveyor roller mechanism or a conveyor belt 208 mechanism.

[0098] In a preferred embodiment, considering that in the prior art, in the assembly process of most battery cell modules, end plates for protection need to be pasted at both ends of the battery cell aggregate in advance for subsequent collar band processes. Therefore, in this embodiment, the battery cell pre-stacking device is further provided with a head end plate sticking mechanism and a tail end plate sticking mechanism for respectively sticking end plates to both ends of the battery cell aggregate. The head end plate sticking mechanism and the tail end plate sticking mechanism can both detachably connect the end plates, and adhesive is applied to the surface of the end plate for bonding with the battery cell aggregate.

[0099] In a specific embodiment, the battery cell output mechanism is arranged at the receiving end to receive the battery cells and can drive the battery cells to move, so as to move the battery cell aggregate away from the original position, not only leaving a position for the next group of battery cell aggregates, but also moving the battery cell aggregate to the position where the next process is carried out. The speed at which the battery cell output mechanism drives the battery cells to move is relatively slow. Specifically, the time required for the battery cell conveying mechanism to drive the battery cells to move a unit length is not less than the time required for the driving mechanism to push the battery cells over, ensuring that there is no gap between the battery cells. A unit length is the total thickness of the battery cells pushed over at one time; the battery cell input mechanism 211 and the driving mechanism are both arranged close to the receiving end. The transportation direction of the battery cell input mechanism 211 is perpendicular to the transportation direction of the battery cell output mechanism, and the pushing direction of the driving mechanism is the same as the transportation direction of the battery cell output mechanism; the head end plate sticking mechanism and the tail end plate sticking mechanism are both arranged on the battery cell output mechanism, and the tail end plate sticking mechanism is arranged farther away from the receiving end than the head end plate sticking mechanism. That is, when the battery cell aggregate moves on the battery cell output mechanism, it will first cross the tail end plate sticking mechanism, and then the tail end plate sticking mechanism will perform the action of sticking the end plate. Such a setting is not only structurally compact but also prevents mutual interference.

[0100] In addition, battery cell limit plates 210 are provided on both sides of the receiving end of the battery cell output mechanism and on both sides of the position where the battery cell aggregate is formed. Guide wheels that can be in rolling contact with the battery cells are provided on the battery cell limit plates 210 to correct the positions of the battery cells when they reach the battery cell output mechanism and also ensure smooth movement of the battery cells.

[0101] In an optional embodiment, a head-end sticking plate mechanism is provided, including a first clamping plate assembly 201 and a tenth power assembly 202; wherein the first clamping plate assembly 201 is capable of clamping and releasing the end plate, and specifically, the first clamping plate assembly 201 can include two clamping plates, a bidirectional cylinder or a bidirectional ball screw for driving the two clamping plates to move closer to and away from each other, and of course, the first clamping plate assembly 201 can also be replaced by an electric suction cup; the tenth power assembly 202 drives the first clamping plate assembly 201 to move in a direction perpendicular to the arrangement direction of the battery cell assembly, which can be a vertical movement or a horizontal movement, so that the first clamping plate assembly 201 can be aligned with and staggered with the battery cells entering the battery cell output mechanism, and specifically, the tenth power assembly 202 can be a pneumatic cylinder or a ball screw for driving the two clamping plates to move closer to and away from each other. Cylinder, hydraulic cylinder or other linear actuator; when the first clamping plate assembly 201 is facing the battery cell entering the battery cell output mechanism, the end plate clamped by it can face the battery cell entering the battery cell output mechanism, or it can be said that the first clamping plate assembly 201 is clamped on two opposite plate edges of the end plate, and the force direction of the first clamping plate assembly 201 is parallel to the plate surface of the end plate. The first clamping plate assembly 201 fixes the end plate and waits for the battery cell. When the first battery cell of each battery cell assembly reaches the battery cell output mechanism and is bonded to the end plate, the first clamping plate assembly 201 releases the end plate and is staggered with the battery cell entering the battery cell output mechanism under the drive of the tenth power assembly 202, so as not to hinder the battery cells pushed from behind to be arranged one by one and pushed forward.

[0102] In an optional embodiment, a tail end sticking plate mechanism is provided including a second clamping plate assembly 203, an eleventh power assembly 204, and a twelfth power assembly 205; wherein, the second clamping plate assembly 203 is capable of clamping and releasing the end plate, and specifically, the second clamping plate assembly 203 can include two clamping plates, a bidirectional cylinder or a bidirectional ball screw that drives the two clamping plates to move closer to and away from each other, and of course, the second clamping plate assembly 203 can also be replaced with an electric suction cup; the eleventh power assembly 204 drives the second clamping plate assembly 203 to move in a direction perpendicular to the arrangement direction of the battery cell assembly, which can be a vertical movement or a horizontal movement, so that the second clamping plate assembly 203 can be opposite to and staggered with the battery cell assembly; the twelfth power assembly 205 is provided on the eleventh power assembly 204 and drives the second clamping plate assembly 203 to reciprocate along the moving direction of the battery cell assembly, so that the end plate clamped by the second clamping plate assembly 203 when it is facing the battery cell assembly can contact the battery cell assembly. When the battery cell assembly is gradually arranged on the battery cell output mechanism, the second clamping plate assembly 203 clamps and fixes the end plate in a staggered position. When the last battery cell of the battery cell assembly is in place, the eleventh power assembly 204 drives the second clamping plate assembly 203 to move to face the end of the battery cell assembly that is not bonded with the end plate, and then the twelfth power assembly 205 drives the second clamping plate assembly 203 to press the end plate on the battery cell assembly in the horizontal direction, and after completion, it leaves the staggered position again. It should be noted that the eleventh power assembly 204 and the twelfth power assembly 205 can be specifically set as a cylinder, a hydraulic cylinder or other linear actuators.

[0103] In a specific embodiment, a pushing mechanism is provided, including a pushing body 206, a thirteenth power assembly 207, and a frame. The thirteenth power assembly 207 drives the corresponding pushing body 206 to move back and forth along the arrangement direction of the battery cell assembly to push the battery cell from the battery cell input mechanism 211 to the battery cell output mechanism; the combination formed by the pushing body 206 and the thirteenth power assembly 207 is provided with at least two groups, and all the pushing bodies 206 move alternately, further improving the work efficiency. The pushing body 206 is a plate-shaped body that can contact the surface of the battery cell. The pushing body 206 is connected to the thirteenth power assembly 207 through a pushing frame that plays a connecting role, and the pushing frame and the frame are connected by a sliding block and a slide rail structure, so that the movement of the pushing body 206 is more stable. The thirteenth power assembly 207 can be specifically set as a cylinder, a hydraulic cylinder or other linear actuators. In addition, in this embodiment, the battery cell input mechanism 211 is arranged below the slider and slide rail structure on the frame, making full use of space and having a compact structure.

[0104] Furthermore, in order to optimize the operation effect and make the pushing effect of the push body 206 on the battery cell more accurate, it is preferred to set the pushing mechanism to also include a blocking body and a fourteenth power assembly. The fourteenth power assembly drives the blocking body to move up and down, so that the blocking body can block the battery cell located on the battery cell input mechanism 211 and directly opposite to the push body 206, that is, when the battery cell reaches the position directly opposite to the push body 206, it is first blocked by the blocking body, and after stabilizing the position, the push body 206 moves again, which can ensure that the position where the push body 206 applies thrust to each battery cell is the same. The fourteenth power assembly can be specifically set as a cylinder, a hydraulic cylinder or other linear actuator. In addition, if the position of the blocking body corresponding to the battery cell input mechanism 211 is the last position of the transportation of the battery cell input mechanism 211, the fourteenth power assembly can be driven to drive the blocking body to be in a blocking state; if the battery cell input mechanism 211 has a transportation section after passing the pushing mechanism, the position of the blocking body can be set to change intermittently to prevent the battery cells from over-accumulating at the pushing mechanism.

[0105] In an optional embodiment, a battery cell output mechanism is provided including a conveyor belt 208 and a fifteenth power assembly 209; wherein, the conveyor belt 208 receives the battery cell assembly, and at least a portion thereof is two parallel belts capable of suspending the battery cell assembly, or it may be provided as two belts throughout the entire body; the fifteenth power assembly 209 drives the two conveyor belts 208 to rotate synchronously and cyclically, and the fifteenth power assembly 209 may be specifically provided as including a driving wheel, a driven wheel connected to the driving wheel by a synchronous belt, and a motor driving the driving wheel to rotate.

[0106] Further, based on the above-mentioned battery cell pre-stacking device, an assembly transport device is provided, including a slide rail, a slide table, a sixteenth power assembly, a lifting platform, and a seventeenth power assembly; wherein the slide rail is arranged parallel to and below the conveyor belt 208; the slide table is slidably connected to the slide rail; the sixteenth power assembly drives the slide table and the slide rail to slide relative to each other; the lifting platform is arranged on the slide table; the seventeenth power assembly is arranged on the slide table, and drives the lifting platform to rise and fall in the space between the two conveyor belts 208; the shaping device 4 is arranged above the two conveyor belts, and the width of the lifting platform is less than the distance between the two conveyor belts 208. When the battery cell assembly is transported to the bottom of the shaping device 4, the slide table slides over, and the lifting platform rises, and can pass through the conveyor belt, lift up and receive the battery cell assembly on the conveyor belt 208, so that the battery cell assembly rises to a shaping position that can receive the force of the shaping device 4, and the shaping position is the position between the two strips 401 of the whole machine mechanism. The sixteenth power assembly and the seventeenth power assembly can be specifically arranged as a cylinder, a hydraulic cylinder or other linear actuators.

[0107] In another specific embodiment, Figure 2As shown, the assembly moving device 5 includes a fixed frame 501, a mobile frame 502, a fourth power assembly 505, and a clamping mechanism; wherein the mobile frame 502 is slidably connected to the fixed frame 501; the fourth power assembly 505 is arranged on the fixed frame 501 and can drive the mobile frame 502 to slide back and forth; the clamping mechanism is arranged on the mobile frame 502, and can clamp the battery cell assembly transported to the fixed frame 501, and pressurize the battery cell assembly along the arrangement direction of the battery cells. In this way, the clamping mechanism pressurizes the battery cell assembly while keeping its position relatively fixed, and drives the battery cell assembly to move while maintaining the pressurized state, integrating the pressurization process and the moving process of the battery cell assembly, as well as the socketing process, with a compact structure, saving space and cost. The fourth power assembly 505 can be specifically set as a cylinder, a hydraulic cylinder or other linear actuator.

[0108] Further, the clamping mechanism includes a first limit plate 503, a second limit plate 504, and a fifth power assembly; wherein the second limit plate 504 is arranged opposite to the first limit plate 503; the fifth power assembly is connected to at least one of the first limit plate 503 and the second limit plate 504, and can drive the first limit plate 503 and the second limit plate 504 to approach each other, so that the first limit plate 503 and the second limit plate 504 can clamp the battery cell assembly along the arrangement direction of the battery cells and pressurize the battery cell assembly, and when the fifth power assembly drives the first limit plate 503 and the second limit plate 504 to move away from each other, the pressure on the battery cell module is removed, thereby releasing the battery cell module. In this way, the pressure control of the battery cell assembly is achieved by controlling the position between the first limit plate 503 and the second limit plate 504, which is simple and direct, and the effect is obvious. The fifth power assembly can be specifically set as a cylinder, a hydraulic cylinder or other linear actuator.

[0109] In a preferred embodiment, a fifth power assembly is provided to be connected to the first limit plate 503, and the clamping mechanism further includes a sixth power assembly 506 for driving the second limit plate 504 to move. The second limit plate 504 is slidably connected to the mobile frame 502, so that the second limit plate 504 can face and stagger with the first limit plate 503. In this way, the second limit plate 504 can block the end of the battery cell assembly or leave the end of the battery cell assembly, and the first limit plate 503 always blocks the end. When the second limit plate 504 is staggered with the first limit plate 503, the battery cell assembly is transported over, passes through the second limit plate 504 and reaches the fixed frame 501, and then the second limit plate 504 faces the first limit plate 503, so that the battery cell assembly is sandwiched in the middle, which is also conducive to the module assembly device and other devices in the battery module assembly process.

[0110] It should be noted that, in order to protect the battery cells from damage during the strapping process, generally both ends of the battery cell assembly are arranged with end plates, and the end plates have depressions. Preferably, the first limiting plate 503 and the second limiting plate 504 are provided with protrusions on the side opposite to the battery cell assembly, and the protrusions can match with the end plates at the ends of the battery cell assembly, so that the position stability between the first limiting plate 503 and the second limiting plate 504 and the battery cell assembly can be enhanced.

[0111] More specifically, a fixed slide rail 507 is provided on the fixed frame 501, and a slider 508 that slides with the fixed slide rail 507 is provided on the movable frame 502, thereby realizing a sliding connection. The battery cell assembly is located on the side of the movable frame 502 facing the strapping device 8 and below the fixed slide rail 507, so that the battery cell assembly can be moved to a position beyond the fixed slide rail 507. In this way, when the battery cell assembly moves to the strapping device 8, there are no obstructions in the upper and lower directions, ensuring that the fixed slide rail 507 will not interfere with the strapping process.

[0112] In another specific embodiment, Figure 3 As shown, the belt-wrapping device 8 includes a belt-holding mechanism and a first power assembly 801; wherein, the belt-holding mechanism can fix the endless belt and tighten the endless belt in the outward peripheral direction, that is, the endless belt expands outward with the center as the base point; the first power assembly 801 drives the belt-holding mechanism to move back and forth along the through-direction of the endless belt, so that the endless belt can be wrapped around the battery cell assembly; the combination formed by the belt-holding mechanism and the first power assembly 801 is provided with two relatively distributed groups, and when the battery cell assembly is located between the two belt-holding mechanisms, the two groups of combinations each wrap a endless belt around the battery cell assembly, or in other words, the two groups of combinations are respectively located on the upper and lower sides of the material receiving station 9. With such arrangement, the belt holding mechanism, driven by the first power component 801, approaches the target belt to obtain connection and at the same time tightens the belt, so that the belt is stretched and expanded, increasing the space inside, and then driven by the first power component 801 to approach the battery cell assembly, thereby smoothly and gradually putting the belt around the battery cell assembly. After the belt holding mechanism removes the force, the belt is tightly clamped around the battery cell assembly. The two groups of combinations run at the same time, and the two sides are put on together to improve the belt putting efficiency, which solves the problem of difficulty in connecting the steel belt and the battery cell module in the assembly of the battery cell module in the prior art, resulting in low assembly efficiency of the battery cell module.

[0113] In a specific embodiment, the belt holding mechanism includes a mounting frame 802, a first support member 803, a second support member 804, a second power assembly 805, a first pull member 806, a second pull member 807, and a third power assembly 808; wherein the mounting frame 802 is connected to the first power assembly 801; the second support member 804 is arranged opposite to the first support member 803; the second power assembly 805 drives the first support member 803 and the second support member 804 to move closer to and away from each other; the second pull member 807 is arranged opposite to the first pull member 806; the third power assembly 808 drives the first pull member 806 and the second pull member 807 to move closer to and away from each other; the first The support member 803, the second support member 804, the second power assembly 805, the first pull member 806, the second pull member 807 and the third power assembly 808 are all arranged on the mounting frame 802. Driven by the first power assembly 801, the first support member 803 and the second support member 804 extend into and out of the endless belt. The first support member 803 and the second support member 804 can extend into the inner side of the two short sides of the endless belt and move away from each other to stretch the endless belt in a direction perpendicular to the short side of the endless belt; the first pull member 806 and the second pull member 807 can be detachably connected to the outer side of the two long sides of the endless belt and move away from each other to pull the endless belt in a direction perpendicular to the long side of the endless belt. The first support member 803 and the second support member 804 can be specifically arranged in a right-angle claw shape. Taking the first support member 803 as an example, it includes two parallel L-shaped slats, and the distance between the L-shaped slats is slightly smaller than the length of the short side of the endless belt. The vertical part is used to insert into the inner side of the endless belt, and the horizontal part is located outside the endless belt and separated by a distance. In this arrangement, the ring belt is firstly stretched from the inside to the outside by the action of the first supporting member 803 and the second supporting member 804, and this action keeps the ring belt and the first supporting member 803 and the second supporting member 804 in a fixed position, and then the first pulling member 806 and the second pulling member 807 are manipulated to pull the ring belt from the outside, so that all four sides of the ring belt are stretched. In addition, the belt holding mechanism can also be configured as a supporting member that supports from the inside to the outside.

[0114] After the sleeve connection is completed, the supporting force applied by the first supporting member 803 and the second supporting member 804 and the pulling force applied by the first pulling member 806 and the second pulling member 807 are withdrawn, and then the first power component 801 drives the entire belt holding mechanism to leave the battery core module.

[0115] The second power assembly 805 is configured as two cylinders connected to the first support member 803 and the second support member 804 respectively, and can also be configured as a double-headed cylinder connected to both the first support member 803 and the second support member 804.

[0116] Further, the third power assembly 808 is provided to include a bidirectional ball screw and a motor. Among them, the bidirectional ball screw includes a screw rod, a first nut and a second nut threadedly connected to the screw rod, and the screw rod is rotatably connected to the mounting bracket 802 through a bearing; the motor is mounted on the mounting bracket 802 and drives the screw rod to rotate; the first pulling member 806 is connected to the first nut, and the second pulling member 807 is connected to the second nut. With such a setting, when the screw rod rotates, the first pulling member 806 and the second pulling member 807 can approach or move away from each other, and the control accuracy is high, which is suitable for controlling the first pulling member 806 and the second pulling member 807 to perform actions with a relatively small displacement range.

[0117] In addition, in order to enhance the stability of the movement of the first pulling member 806 and the second pulling member 807, a guiding structure in the form of a slider 508 and a slide rail can be selectively provided between the first pulling member 806, the second pulling member 807 and the mounting bracket 802.

[0118] In an optional embodiment, both the first pulling member 806 and the second pulling member 807 are externally connected to a negative pressure air pump, and can adsorb the outer side of the endless belt under negative pressure; or, magnetic attraction blocks are provided on both the first pulling member 806 and the second pulling member 807 to adsorb the endless belt made of a material containing iron and nickel, that is, a steel belt, preferably attracted to the outer side of the endless belt; or, both the first pulling member 806 and the second pulling member 807 can approach the endless belt along with the belt holding mechanism and clamp the endless belt on the inner and outer sides of the endless belt. Specifically, both the first pulling member 806 and the second pulling member 807 include two openable and closable clamping plates controlled by air cylinders. In this way, the detachable connection with the endless belt is realized, which is convenient and fast.
