Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0037] The following combination Figures 1 to 7 Describe the battery cell module assembly equipment provided in the embodiments of the present application.

[0038] like Figures 1 to 3As shown, the battery module assembly equipment of the embodiment of the present application includes a working panel 1, a placement rack 2, a strapping tape 3, and an extrusion mechanism 4. At least two placement racks 2 are slidably mounted on the working panel 1 along the width direction of the working panel 1. The placement racks 2 are used to place a single row of battery cells. The ends of the placement racks 2 are provided with a card slot 21. The strapping tape 3 is annular and the end band body 31 is inserted into the end band slot 21 of at least one placement rack 2. The side band body 32 of the strapping tape 3 protrudes from the outside of the placement rack 2. The strapping tape 3 is used to be taken upward from the placement rack 2 and sequentially put on the outer peripheral surface of at least one row of battery cells. The extrusion mechanism 4 is used to extrude and assemble at least one row of battery cells to form a battery module.

[0039] Specifically, the strapping strap 3 in this embodiment is preferably rectangular in shape. The end straps 31 of the strapping strap 3 are formed of two opposing strap sections along the length of the work panel 1, while the side straps 32 of the strapping strap 3 are formed of two opposing strap sections along the width of the work panel 1. The strapping strap 3 can be made of stainless steel, nickel-plated steel, or titanium alloy, and is used to tightly bundle single or multiple rows of battery cells into a rigid battery module to prevent displacement due to vibration or collision.

[0040] Specifically, the working panel 1 is equipped with a push-pull cylinder 11 that drives the placement rack 2 to slide. This mechanically controls the placement rack 2's movement, ensuring a more stable and precise movement. A product detection grating 22 is located at one end of the placement rack 2 to detect the proper alignment of the individual battery cells, thereby determining if the number of individual cells is sufficient and no more cells need to be added. A strapping detection grating 23 is also located at one end of the placement rack 2, adjacent to the product detection grating 22, to determine if the strapping 3 is pre-installed on the placement rack 2.

[0041] For ease of understanding, let's take two placement racks 2 as an example. When assembling a single row of cells, any placement rack 2 can be selected and the square individual cells can be stacked sequentially along the length of the work panel 1. Once the product inspection grating 22 detects that the individual cells are in place, no more cells are placed. The strapping tape 3 pre-installed on the placement rack 2 has a profile that is roughly the same size as the cell module consisting of the single row of cells.

[0042] Next, the extrusion mechanism 4 squeezes the single-row battery cells, eliminating the gaps between them and allowing the structural adhesive between the cells to flow evenly to form a glue layer, increasing the adhesive strength and achieving a connection between the cells. The strapping tape 3 is then removed from the slot 21 from bottom to top. The strapping tape 3, while maintaining its overall shape, is sequentially inserted into the battery module directly above. Since the side bands 32 of the strapping tape 3 protrude outward, they are easily grasped and inserted upwards, making it simple and convenient. Another strapping tape 3 is then taken from the outside and inserted into the battery module from top to bottom, i.e., two strapping tapes 3 are inserted into the battery module, separated from each other. Subsequently, the extrusion mechanism 4 releases the extrusion force, and the battery cells expand, tightening the strapping tape 3, thereby bundling the battery cells and preventing them from loosening.

[0043] When assembling a double-row battery cell, the steps are similar to those described above, except that the push-pull cylinder 11 controls the closing of the two placement racks 2, and two rows of battery cells are placed on the two placement racks 2. The outline size of the steel strip is larger than the former, and is basically the same as the size of the battery module composed of the double-row battery cells. The end strip 31 of the steel strip is inserted into the end slot 21 of the two placement racks 2, and the side strip 32 of the strapping tape 3 protrudes from the two placement racks 2, thereby making it easy to take and put the strapping tape 3 and bundle the double-row battery cell module. Therefore, through the design of multiple placement racks 2 and the different pre-installation methods of the strapping tape 3, the device can be applied to both single-row and multi-row battery cell extrusion stacking, thereby improving the compatibility and adaptability of the device.

[0044] In some embodiments, continue to refer to Figure 1 and Figure 2 The extrusion mechanism 4 includes an extrusion member 41 and a positioning member 42, which are respectively placed on both sides of the placement frame 2 along the length direction of the working panel 1. The extrusion member 41 is slidably assembled on the working panel 1 along the length direction of the working panel 1, and the positioning member 42 is assembled on the working panel 1. The working panel 1 is provided with a linear drive 43 that drives the extrusion member 41 to slide toward the positioning member 42.

[0045] Specifically, the linear drive 43 includes a servo electric cylinder.

[0046] Therefore, when the extruding member 41 approaches the positioning member 42 under the action of the linear driver 43, it can cooperate with the positioning member 42 to extrude and assemble the battery cells arranged in the middle, thereby compacting and forming a battery cell module.

[0047] In some embodiments, continue to refer to Figure 2 The output end of the linear driver 43 is connected to the extrusion piece 41 through a pressure sensor 44. The pressure sensor 44 is used to detect the extrusion force of the extrusion piece 41 on the battery cell.

[0048] The pressure sensor 44 thus detects the squeezing force of the battery cell in real time, thereby preventing excessive pressure from damaging the battery cell.

[0049] In some embodiments, continue to refer to Figure 2 and Figure 5 The extrusion member 41 and the positioning member 42 have the same structure, both including a stand 421 for mounting the end plate 426 and a height locator provided on the stand 421. The height locator includes a position carrier 422 that can slide up and down and an adjusting component 423 for adjusting the height position of the position carrier 422. The position carrier 422 is used to abut against the bottom of the end plate 426 to locate the height position of the end plate 426.

[0050] Specifically, the adjusting component 423 can be a threaded structure, an electric telescopic rod, etc., to achieve linear sliding of the position carrier 422. The position carrier 422 can be a carrier plate, a supporting plate, etc.

[0051] Therefore, before installing the end plate 426, the height position of the position carrier 422 can be adjusted by adjusting the component 423, and then the installation position of the end plate 426 can be positioned, so that the end plate 426 after being installed on the stand 421 can face the battery cell, thereby providing uniform extrusion pressure for the battery cell.

[0052] In some embodiments, continue to refer to Figure 5 The height locator also includes a telescopic device 424 located below the end plate 426 and mounted on the stand 421 , and the position carrier 422 and the adjustment component 423 are both mounted on the telescopic end of the telescopic device 424 .

[0053] Specifically, the telescopic device 424 can be a telescopic electric cylinder, a hydraulic cylinder, a pneumatic cylinder, etc. If the adjustment component 423 adopts a threaded structure, the threaded structure can include an adjustment bolt vertically mounted on the telescopic end of the telescopic device 424, with the top end of the adjustment bolt abutting against the bottom of the position carrier 422. The upward and downward sliding of the position carrier 422 can be controlled by the threaded movement of the adjustment bolt.

[0054] The design of the telescopic device 424 can thus control the retraction and extension of the position carrier 422 , that is, the position carrier 422 works when extended and hides when retracted, thereby preventing the position carrier 422 from mechanically interfering with other components.

[0055] In some embodiments, continue to refer to Figure 5 and Figure 6 An end plate detection grating 425 is provided at a position in the stand 421 for mounting the end plate 426 , and the end plate detection grating 425 is used to detect whether the end plate 426 is in place.

[0056] In other embodiments, the positioning member 42 and the extrusion member 41 have the same structure, and the same parts are the same as above. The difference lies in that the stand 421 of the positioning member 42 is also slidably assembled on the working panel 1, but after sliding to the set position, it is connected to the working panel 1 by bolts, thereby achieving the fixation of the positioning member 42 on the working panel 1. The stand 421 of the positioning member 42 includes a frame 4211 for mounting the end plate 426 and the height positioner, and a base 4212 for slidingly assembling the frame 4211 along the length direction of the working panel 1. The base 4212 is provided with a pen-shaped cylinder 4213 for driving the frame 4211 to slide and control the position of the frame 4211. The pen-shaped cylinder 4213 can further refine the position of the end plate 426 to facilitate alignment and receiving the battery cells. A positioning block 4214 is embedded in the frame 4211 for vertical sliding movement, and a double-acting cylinder 4215 is provided for controlling the sliding of the positioning block 4214. A positioning groove corresponding to the positioning block 4214 is provided on the base 4212. When the frame 4211 drives the positioning block 4214 to slide to the positioning groove, the double-acting cylinder 4215 controls the positioning block 4214 to be inserted into the positioning groove, thereby locking the frame 4211 and the base 4212, preventing the frame 4211 from retreating relative to the base 4212 when subjected to the extrusion force of the battery cell, thereby ensuring the stability and accuracy of the extrusion assembly process.

[0057] In some embodiments, continue to refer to Figure 1 and Figure 2 The battery cell module assembly equipment also includes a flat pressing mechanism 5 arranged on both sides of the placement rack 2 along the width direction of the working panel 1. The flat pressing mechanism 5 includes a lifting unit 51, a translation unit 52 arranged at the output end of the lifting unit 51, and a flat pressing piece 53 arranged at the output end of the translation unit 52. The flat pressing pieces 53 of the two flat pressing mechanisms 5 are used to center and flatten multiple battery cells after arrangement.

[0058] Specifically, the lifting unit 51 can adopt a lifting cylinder that can be extended up and down, the translation unit 52 can adopt a translation cylinder that can be extended along the width direction of the working panel 1, and the flat pressing piece 53 is a flat pressing arm, flat pressing bar, etc. extending along the length direction of the working panel 1.

[0059] When the device is idle, the lifting unit 51 can position the flattening piece 53 below the placement rack 2, hiding it and preventing it from being exposed and potentially causing collisions or injuries. During use, the lifting unit 51 can control the flattening piece 53 to rise above the placement rack 2, facing the arranged battery cells. The translation unit 52 controls the two flattening pieces 53 to center and press the arranged battery cells, preventing them from shifting or deflecting across the width of the working panel 1 and facilitating subsequent compression by the compression mechanism 4 in the direction of the battery cell arrangement.

[0060] In some embodiments, continue to refer to Figures 2 to 4The placement rack 2 includes at least two placement bars 24 arranged adjacent to each other along the width direction of the working panel 1. The at least two placement bars 24 are connected by a connecting plate 25. A safety locking piece 26 is movably inserted on the connecting plate 25. A locking hole 12 corresponding to the safety locking piece 26 is provided on the working panel 1. The locking hole 12 is used for the safety locking piece 26 to be inserted when sliding to lock the position of the placement rack 2.

[0061] Specifically, the connecting plate 25 is provided with a through hole, and the safety locking piece 26 is movably inserted into the through hole, thereby realizing the movable insertion on the connecting plate 25. It can be understood that the safety locking piece 26 can be freely removed from the through hole.

[0062] During equipment maintenance, the safety locking piece 26 can be pre-placed, and the placement rack 2 can be locked on the work panel 1 by the cooperation of the safety locking piece 26 and the locking hole 12. This prevents the maintenance worker from accidentally touching the start button and moving the placement rack 2, thereby squeezing or crushing the human body.

[0063] In some embodiments, continue to refer to Figure 1 The battery module assembly equipment also includes a stand 6, which has a stacking station and a bundling station. The working panel 1 can be slidably assembled on the stand 6 along the length direction so as to exchange positions between the stacking station and the bundling station. A linear drive 61 is connected between the stand 6 and the working panel 1 to drive the working panel 1 to slide on the stand 6.

[0064] Specifically, continue to refer to Figure 7 The linear actuator 61 includes a drive motor 611, a gear 612, and a rack 613. The rack 613 is fixed to the stage 6 and extends along the length of the working panel 1. The drive motor 611 is mounted on the working panel 1. The gear 612 is located at the output end of the drive motor 611 and meshes with the rack 613. When the drive motor 611 drives the gear 612 to rotate, the gear 612 moves along the extension direction of the rack 613 due to the meshing action, thereby driving the working panel 1. In other embodiments, the linear actuator 61 may also adopt a linear guide rail, a linear guide rail, etc.

[0065] It is understandable that, referring to Figure 1 and Figure 2 The above-mentioned flat pressing mechanism 5 is arranged on the platform 6, that is, the jacking unit 51 is installed on the platform 6.

[0066] Thus, the working panel 1 can perform the extrusion assembly of the battery cells at the stacking station and avoid the interference of the flat pressing mechanism 5 at the bundling station, facilitating the manual bundling operation of the battery cells. The dual-station design can make the operation step-by-step and process-oriented, more organized and safer.

[0067] In some embodiments, continue to refer to Figure 1The platform 6 is provided with a safety grating 62 at the strapping station. The safety grating 62 is used to detect the stopping state of the working panel 1 at the strapping station.

[0068] When the working panel 1 moves toward the strapping station, the safety light barrier 62 is open. Once the working panel 1 comes to a complete stop at the strapping station, the safety light barrier 62 closes. This provides feedback on the working panel 1's movement, primarily its state when it comes to a complete stop, helping the operator determine the panel's stability and safety. The operator can confirm the strapping operation by checking the safety light barrier 62's closure, making it more reliable and stable.

[0069] In the present application, it is understood that when extruding single-row, double-row or other multiple-row battery cells, end plates 426 of different widths can be adaptively replaced to ensure a uniform extrusion effect.

[0070] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
