Description

Technical Field

[0001] This invention relates to the field of battery module assembly technology, specifically to a dual-station cross-circulation new energy battery module assembly line. Background Technology

[0002] With the surge in global demand for clean energy, new energy vehicles and energy storage systems have become key development directions. As their core component, the production and manufacturing technology of power battery modules, especially their automated assembly efficiency and quality, is directly related to the cost, performance and safety of the final product.

[0003] Battery modules are typically composed of multiple individual battery cells stacked together. In traditional automated assembly processes, in order to ensure electrical insulation and thermal management performance between battery cells, heat insulation or insulating materials need to be placed between adjacent battery cells. When existing automated production lines complete this process, the process is usually step-by-step: First, individual battery cells are transported to the assembly station by conveyor lines or robots and arranged into an initial battery cell assembly prototype. Then, heat insulation sheets are manually or by grabbing them and pasting them one by one or in batches onto the designated side of the battery cells. After the heat insulation sheets are pasted, another set of alignment mechanisms is activated to push all the battery cells towards the center, so that they are finally aligned in a straight line and pressed tightly against each other to form a compact battery cell stack.

[0004] In the above process, the alignment of the battery cells and the installation of the heat insulation sheet are two independent and sequential processes that require different actuators to complete in steps. This sequential working mode makes the entire assembly process lengthy, significantly increases the production cycle time, and limits the improvement of the overall efficiency of the production line. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a dual-station cross-circulation new energy battery module assembly line, which can effectively solve the problem that in the existing technology, the alignment of the battery cells and the mounting of the heat insulation sheet are two independent processes that are executed sequentially and require different actuators to complete them step by step. This serial working mode makes the entire assembly process lengthy, significantly increases the production cycle time, and limits the improvement of the overall efficiency of the production line.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a dual-station cross-cycle new energy battery module assembly line, comprising: The workbench has symmetrically arranged placement areas for placing battery cells, and an arrangement area at the center of the workbench. Strip-sticking mechanisms are evenly arranged in the placement areas. Corresponding strip-sticking mechanisms in two placement areas are staggered. Adjacent strip-sticking mechanisms in the same placement area are connected by connecting plates. The workbench is also connected to a centering mechanism that pushes the battery cells from the placement area to the arrangement area. The strip-sticking mechanism is connected to a pressing mechanism that pushes the battery cells in the arrangement area to press and stick together. The labeling mechanism includes a mounting base, which is slidably connected to the worktable via a cylindrical block. Two mounting plates are symmetrically fixedly connected to the side of the mounting base near the arrangement area. A feeding assembly is connected inside the mounting base and between the two mounting plates.

[0007] Furthermore, the feeding assembly includes a mounting base, on which a raw material roller is rotatably connected at a position away from the arrangement area, and a flattening roller is symmetrically rotatably connected on the mounting base on the side closer to the arrangement area. A pressure roller parallel to the flattening roller is also symmetrically rotatably connected on the mounting base. The tops of the corresponding flattening roller and pressure roller are fixedly fitted with meshing transmission gears. A recovery roller is symmetrically rotatably connected on the mounting base at a position between the raw material roller and the pressure roller. The corresponding pressure roller and recovery roller are connected by a belt drive. A tension roller is rotatably connected to the mounting plate on the side closer to the arrangement area.

[0008] Furthermore, a stop plate is fixedly connected to the mounting plate.

[0009] Furthermore, the clamping mechanism includes a connecting strip 1. The lower ends of the cylindrical blocks on the same side are fixedly connected to the connecting strip 1. The two connecting strip 1 are fixedly connected to the push bar by a vertical rod. The connecting strip 1 is fixedly connected to the worktable by a clamping spring. A baffle is fixedly connected to the worktable surface.

[0010] Furthermore, the centering mechanism includes a guide groove, which is provided on the workbench and on the left side of the mounting plate. A push seat is slidably connected to the guide groove via a connecting block. The lower ends of multiple connecting blocks on the same side are fixedly connected to a second connecting strip. The lower ends of two second connecting strips are fixedly connected to an electric cylinder via a telescopic plate.

[0011] Furthermore, the guide channel adopts a three-section design, consisting of two inclined sections with the same slope and a transverse section connecting the two inclined sections.

[0012] Furthermore, a centering plate is fixedly connected to the side of the pusher seat away from the push bar.

[0013] Furthermore, a connecting shaft is fixedly connected to the upper end of the recovery roller near the push bar on the mounting base. A wedge is rotatably sleeved on the connecting shaft. The wedge is connected to the mounting base via a torsion spring. Limiting strips are connected to the lower end of the wedge and the mounting base to allow it to rotate only in the direction close to the push bar. An adjusting gear is fixedly sleeved on the top end of the connecting shaft. A U-shaped frame is symmetrically fixedly connected to the worktable. A rack that meshes with the adjusting gear is slidably connected to the U-shaped frame via a return spring. The end of the rack away from the push bar is provided with a chamfer that matches the wedge.

[0014] The technical solution provided by this invention has the following advantages compared with the prior art: 1. In this embodiment, the positive and negative cells are pre-sorted by an external robotic arm and placed in two symmetrical placement areas on the workbench. After the centering mechanism is activated, the two push seats move synchronously along the guide groove, pushing the cells obliquely towards the arrangement area. Finally, they are staggered and stacked like comb teeth, directly realizing the staggered arrangement of positive and negative cells. This avoids the time-consuming serial operation of the traditional "grab-flip-place" process and eliminates the time-consuming cell flipping step in the traditional process. By processing the positive and negative cells in parallel through the dual placement areas, the production cycle is shortened by a factor of two.

[0015] 2. In this embodiment, when the centering mechanism's pusher moves along the transverse section of the guide groove, it pushes the battery cell closer to the strip attaching mechanism. The side of the battery cell contacts and adheres to the heat insulation sheet of the strip attaching mechanism. At the same time, the mounting base and mounting plate move synchronously through the abutment plate. During this process, the heat insulation sheet is automatically attached to the surface of the battery cell. After the battery cell continues to move to the arrangement area, the two are separated by misalignment, realizing the synchronous completion of "battery cell transportation" and "heat insulation sheet attachment". The heat insulation sheet attachment is embedded in the battery cell transportation process, breaking the traditional step-by-step mode of "arrange first, then attach" and reducing process changeover time.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments. Example

[0021] Please see Figures 1-9 This invention provides a technical solution: a dual-station cross-circulation new energy battery module assembly line, comprising: The workbench 1 has symmetrically arranged placement areas 11 for placing battery cells. An arrangement area 12 is arranged at the center of the workbench 1. Strip-sticking mechanisms 2 are evenly arranged in the placement areas 11. Corresponding strip-sticking mechanisms 2 in two placement areas 11 are staggered. Adjacent strip-sticking mechanisms 2 are connected by connecting plates 3. The workbench 1 is also connected to a centering mechanism 4 that pushes the battery cells from the placement areas 11 to the arrangement areas 12. The strip-sticking mechanism 2 is connected to a pressing mechanism 5 that pushes the battery cells in the arrangement areas 12 to press and stick together. The labeling mechanism 2 includes a mounting base 21, which is slidably connected to the workbench 1 via a cylindrical block 211. A mounting plate 22 is symmetrically fixedly connected to the side of the mounting base 21 near the arrangement area 12. A feeding assembly 23 is connected to both the mounting base 21 and the mounting plate 22.

[0022] Specifically, in the traditional automated assembly process of battery cells, multiple battery cells are connected in series to form a battery cell stack. Therefore, the positive and negative terminals of two adjacent battery cells must be alternated. The common practice is to use a robot to flip half of the battery cells 180 degrees in the air or through a special mechanism and then place them in the designated position. This is a serial operation, and the efficiency is limited by the speed of a single "grab-flip-place" cycle. Among them, the "flip" action is particularly time-consuming and is the main efficiency bottleneck of the entire production line.

[0023] To solve the above problems, the flipping action is eliminated in this embodiment. During feeding, the cells with different positive and negative poles are pre-sorted and placed in two placement areas 11. When stacking, the centering mechanism 4 pushes the cells on both sides to move towards the center in an oblique direction at the same time. The cells interlock like comb teeth to complete the stacking. The advantage of this design is that it turns the serial operation into a parallel operation, completely eliminates the most time-consuming flipping link, and shortens the production cycle time by a factor of two.

[0024] To ensure electrical insulation and thermal management performance between battery cells, heat insulation or insulating materials need to be placed between adjacent cells. Existing automated production lines typically use a step-by-step process to complete this step. First, individual cells are transported to the assembly station via conveyor lines or robots and arranged into an initial cell assembly prototype. Then, heat insulation sheets are manually or by grabbing them and pasting them one by one or in batches onto the designated sides of the cells. After the heat insulation sheets are installed, all the cells are pushed towards the center so that they are finally aligned in a straight line and pressed tightly together to form a compact cell stack.

[0025] In the assembly process described above, the alignment of the battery cells and the mounting of the heat insulation sheet are two independent and sequential processes that require different execution components to complete in stages. This sequential working mode makes the entire assembly process lengthy, significantly increases the production cycle time, and limits the improvement of the overall efficiency of the production line.

[0026] To address the aforementioned issues, in this embodiment, an integrated strip-applying mechanism 2 is specifically configured on the workbench 1. This mechanism, in conjunction with the centering mechanism 4 and the clamping mechanism 5, constitutes a complete battery cell processing system. The specific workflow is as follows: When the centering mechanism 4 is activated, it will precisely push the battery cell in the placement area 11 to move along the oblique path to the arrangement area 12. During this process, the battery cell first comes into contact with the heat insulation sheet preset in the strip attaching mechanism 2, and then the strip attaching mechanism 2 will be driven to complete the displacement action synchronously through friction.

[0027] During the synchronous movement phase, the adhesive side of the heat insulation sheet in the strip-applying mechanism 2 adheres to the battery cell, smoothly and accurately attaching the heat insulation sheet to the surface of the battery cell, thus realizing the automatic application of the heat insulation sheet. After the heat insulation sheet application process is completed, as the battery cell continues to move towards the arrangement area 12 under the action of the centering mechanism 4, a positional shift gradually occurs between the battery cell and the strip-applying mechanism 2, eventually achieving misalignment and separation, and the battery cell smoothly enters the arrangement area 12.

[0028] Once all the cells are arranged in the arrangement area 12 according to the preset straight trajectory, the centering mechanism 4 automatically triggers the reset program and returns to the initial working position. At the same time, the strip attaching mechanism 2 also completes the reset action, and in the process, it drives the pressing mechanism 5 to reset synchronously, applying a pushing force to the multiple cells arranged in a straight line in the arrangement area 12, so that the cells squeeze each other and fit tightly together, and finally form a stable cell stack.

[0029] The significant advantage of the above design lies in the fact that by seamlessly embedding the key processing step of attaching the heat insulation sheet into the process of transporting the battery cells to the central area, it breaks the traditional model where the transport and processing steps are independent of each other in production, and truly realizes the integrated operation of transport and processing. This integrated design not only reduces the changeover time between processes, but also simplifies the overall operation of the equipment, thereby greatly improving the production efficiency of the battery cell stack.

[0030] The feeding assembly 23 includes a raw material roller 231. The raw material roller 231 is rotatably connected to the mounting base 21 at a position away from the arrangement area 12. A flattening roller 232 is symmetrically rotatably connected to the mounting base 21 on the side close to the arrangement area 12. A pressing roller 233 parallel to the flattening roller 232 is also symmetrically rotatably connected to the mounting base 21. The tops of the corresponding flattening roller 232 and pressing roller 233 are fixedly fitted with meshing transmission gears 234. A recovery roller 235 is symmetrically rotatably connected to the mounting base 21 at a position between the raw material roller 231 and the pressing roller 233. The corresponding pressing roller 233 and recovery roller 235 are connected by belt drive. A tensioning roller 236 is rotatably connected to the mounting plate 22 on the side close to the arrangement area 12. A stop plate 25 is fixedly connected to the mounting plate 22.

[0031] Specifically, in this embodiment, the heat insulation sheet is made of rolled material and is sleeved on the raw material roller 231. A diaphragm is provided on both sides of the heat insulation sheet to prevent the rolled heat insulation sheets from sticking together. The side of the heat insulation sheet facing the battery cell is sticky, and the diaphragm in contact with this side is not sticky. The other side of the heat insulation sheet is not sticky, and the corresponding diaphragm in contact with this side is sticky. The non-sticky diaphragm first passes through the gap between the two flattening rollers 232, then passes through the gap between the flattening roller 232 and the pressure roller 233 away from the mounting plate 22, and is wound onto the recovery roller 235 away from the mounting plate 22. The sticky diaphragm first passes through the gap between the two flattening rollers 232, is wound around the tension roller 236, then passes through the gap between the flattening roller 232 and the pressure roller 233 near the mounting plate 22, and is wound onto the recovery roller 235 near the mounting plate 22.

[0032] The clamping mechanism 5 includes a connecting strip 51. The lower ends of the cylindrical blocks 211 on the same side are fixedly connected to the connecting strip 51. The two connecting strips 51 are fixedly connected to the push strip 52 by a vertical rod. The connecting strip 51 is fixedly connected to the worktable 1 by a clamping spring 53. A baffle 54 is fixedly connected to the table surface of the worktable 1.

[0033] The centering mechanism 4 includes a guide groove 41. The guide groove 41 is provided on the workbench 1 and on the left side of the mounting plate 22. A push seat 43 is slidably connected to the guide groove 41 through a connecting block 42. The lower ends of multiple connecting blocks 42 on the same side are fixedly connected to a connecting strip 44. The lower ends of two connecting strips 44 are fixedly connected to an electric cylinder 46 through a telescopic plate 45.

[0034] The guide groove 41 adopts a three-section design, consisting of two inclined sections with the same slope and a transverse section connecting the two inclined sections.

[0035] A centering plate 431 is fixedly connected to the side of the pusher seat 43 away from the push bar 52.

[0036] Specifically, after the external robotic arm sorts and places the battery cells with different positive and negative poles into two independent placement areas 11, the electric cylinder 46 is activated. The telescopic plate 45 drives the connecting strips 44 on both sides to move synchronously, thereby driving the connecting block 42 and the push seat 43 to move together along the guide groove 41. When the connecting block 42 is in the inclined section of the guide groove 41 away from the arrangement area 12, the push seat 43 contacts the battery cell and accurately corrects its initial position. This correction action can eliminate the small deviations when placing the battery cell and lay a stable benchmark for subsequent steps.

[0037] Next, the connecting block 42 enters the transverse section from the inclined section of the guide groove 41, and the pusher 43 pushes the battery cell to move towards the heat insulation sheet until it is aligned with the heat insulation sheet and fits tightly. At the same time, the battery cell drives the mounting plate 22 and the mounting base 21 to move synchronously through the heat insulation sheet and the abutment plate 25 (the clamping spring 53 is compressed). During this process, the compression of the clamping spring 53 not only achieves stable fitting between the battery cell and the heat insulation sheet, but also reserves elastic space for subsequent component reset, taking into account both fitting stability and structural flexibility.

[0038] When the connecting block 42 enters the inclined section of the guide groove 41 near the arrangement area 12, the pusher 43 pushes the battery cell to gradually shift longitudinally, accurately completing the misalignment separation. This misalignment method guided by the tilt angle of the guide groove 41 is more precise and controllable than manual adjustment, ensuring that the misalignment distance of the positive and negative battery cells is consistent. Then the pusher 43 continues to move, pushing the battery cell to the center of the arrangement area 12, ensuring that the center reference of the initial arrangement of the battery cells is unified. The longitudinal section of the pusher allows the pushed battery cell to be centered in the arrangement area 12, and the centering plate 431 connected to it can center adjacent battery cells. Multiple pushers and centering plates 431 work together to arrange multiple battery cells in a straight line with alternating positive and negative polarities.

[0039] Subsequently, the electric cylinder 46 drives the connecting block 42 to reset along the guide groove 41. The pusher seat is reset under the action of the clamping spring 53, and the pusher bar 52 is reset synchronously through the connecting bar 51 and the vertical rod. When the pusher bar 52 is reset, it pushes the battery cells to squeeze each other and fit tightly together, finally forming a stable battery cell stack. The elastic reset action of the clamping spring 53 plays a key role in this step, which can not only ensure the tight fit between the battery cells, but also avoid damage to the battery cells caused by rigid compression, thus ensuring the structural stability and consistency of the battery cell stack. The whole process is highly automated, and no manual intervention is required from sorting to forming. It is suitable for large-scale production and effectively reduces labor costs and operational risks.

[0040] A connecting shaft 26 is fixedly connected to the upper end of the recovery roller 235 near the pusher 52 on the mounting base 21. A wedge block 27 is rotatably sleeved on the connecting shaft 26. The wedge block 27 is connected to the mounting base 21 by a torsion spring and can only rotate towards the pusher 52 under the action of the limiting strip fixedly connected to its lower end and fixedly connected to the mounting base 21. An adjusting gear 28 is fixedly sleeved at the top of the connecting shaft 26. A U-shaped frame 6 is symmetrically fixedly connected to the worktable 1. A rack 29 that meshes with the adjusting gear 28 is slidably connected to the U-shaped frame 6 by a return spring. The end of the rack 29 away from the pusher 52 is provided with a chamfer that matches the wedge block 27.

[0041] Specifically, as the pusher 43 moves along the inclined section of the guide groove 41 near the arrangement area 12, it pushes the battery cell to gradually adhere to the heat insulation sheet, and simultaneously drives the mounting plate 22 and the mounting base 21 to move. After the heat insulation sheet is successfully adhered to the battery cell, as the positional offset between the battery cell and the mounting plate 22 gradually increases, the battery cell will pull the adhesive diaphragm through the adhered heat insulation sheet, thereby driving the two flattening rollers 232 to rotate synchronously in opposite directions. Under the linkage of the transmission gear 234, the corresponding pressure roller 233 also rotates synchronously. At the same time, the belt drive structure drives the recovery roller 235 to rotate in coordination, realizing the orderly winding of the diaphragm. Meanwhile, during the movement of the diaphragm, the next heat insulation sheet to be used will be transported to the position near the backing plate 25, preparing for the next adhesion operation. This linkage design greatly improves the continuity and automation of the heat insulation sheet supply. Since the distance that the battery cell drives the heat insulation sheet to move is exactly equal to the width of a single heat insulation sheet, and a certain gap must be reserved between adjacent heat insulation sheets on the diaphragm (if the gap is insufficient, it will interfere with the bonding accuracy between the battery cell and the heat insulation sheet), the next heat insulation sheet cannot accurately reach the position aligned with the backing plate 25 by relying solely on the direct drive of the battery cell. To solve this problem, this embodiment adds an adjusting gear 28 mechanism. When the push seat 43 pushes the battery cell to move towards the arrangement area 12, the wedge block 27 cannot rotate due to the constraint of the limiting strip. After it contacts the chamfer at the end of the rack 29, it will push the rack 29 to move away from the gear (the return spring is stretched).

[0042] When the pusher seat 43 moves and resets, the wedge block 27, after contacting the rack 29, will rotate towards the pusher strip 52 due to the obstruction of the rack 29. At this time, the adjusting gear 28 meshes with the rack 29 and rotates under the drive of the rack 29, thereby driving the recovery roller 235 near the mounting plate 22 to rotate an additional angle, so that the diaphragm is further wound up, and finally the next heat insulation sheet is precisely pushed to the position aligned with the abutment plate 25, ensuring high-precision docking with the next bonding of the battery cell. This adjustment mechanism, through the ingenious cooperation of the mechanical structure, not only ensures the rationality of the gap between the heat insulation sheets, but also makes up for the problem of insufficient displacement driven by the battery cell alone, significantly improving the accuracy and stability of the heat insulation sheet bonding. At the same time, it does not require a complex electrical control system, reducing equipment costs and maintenance difficulty.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
