Description

Technical Field

[0001] This utility model relates to the field of battery pack assembly technology, and in particular to a processing equipment for sodium-ion batteries. Background Technology

[0002] Sodium-ion battery packs are rechargeable batteries that primarily function by the movement of sodium ions between the positive and negative electrodes. The electrode materials used in sodium-ion batteries are mainly sodium salts, which are more abundant and cheaper than lithium salts.

[0003] As sodium-ion batteries become increasingly widely used, operators are placing higher demands on battery assembly efficiency and quality.

[0004] Currently, sodium-ion battery processing equipment typically uses tooling to assemble cells into battery modules. When multiple battery modules are assembled in parallel to form a battery pack, the assembly process only connects adjacent sets of cell modules with adhesive. The thickness of the adhesive at different positions on the opposite surfaces of adjacent sets of cell modules is inconsistent, which increases thermal resistance at the adhesive layer. This results in differences in heat dissipation efficiency among different battery modules in the battery pack, thus affecting the battery pack's lifespan and structural stability.

[0005] To address the aforementioned issues, there is an urgent need for a processing device for sodium-ion batteries. Utility Model Content

[0057] This embodiment provides a processing apparatus for sodium-ion batteries. The processing apparatus includes a battery module fixture 2000 and a battery pack fixture 1000. The battery module fixture 2000 is used to assemble multiple battery cells into a battery module, wherein the multiple battery cells are arranged in parallel along a second direction. The battery pack fixture 1000 is used to assemble multiple battery modules arranged in parallel along a first direction into a battery pack.

[0058] After the battery cells are produced, multiple cells are first arranged parallel to each other along the second direction on the battery module fixture 2000. Then, the battery module fixture 2000 is used for positioning and assembly to form a battery module. Next, multiple battery modules are arranged parallel and spaced apart. Adhesive is applied between adjacent sets of battery modules. Then, the battery pack fixture 1000 is used to press and fix the multiple battery modules from one side to form a battery pack.

[0059] Among them, such as Figures 1 to 3 As shown, the battery module fixture 2000 includes a second base plate 2100, a second fixing plate 2200, and a second drive assembly 2300. The second fixing plate 2200 is disposed on the second base plate 2100. The first station 2110 is close to the second fixing plate 2200. The second drive assembly 2300 is used to press the battery cells toward the second fixing plate 2200, thereby pressing the battery cells to fix their positions for assembly into a battery module.

[0060] Furthermore, the second base plate 2100 has a first station 2110 and a second station 2120, which are spaced apart along the direction in which the battery cells are parallel. The first station 2110 and the second station 2120 are respectively used to extrude battery modules with different numbers of battery cells. The second drive assembly 2300 can be selectively disposed on one of the first station 2110 and the second station 2120 of the second base plate 2100. The first station 2110 and the second station 2120 are adapted to two specifications of battery modules with different numbers of battery cells, so as to expand the applicability of the battery module tooling 2000.

[0061] Specifically, the first station 2110 and the second station 2120 can be fixed with pre-set fixing holes on the second base plate 2100. When the first station 2110 is needed, the second drive component 2300 is fixed in the first station 2110. When the second station 2120 is needed, the second drive component 2300 is fixed in the second station 2120.

[0062] The second drive assembly 2300 includes a second mounting plate 2320, a second lead screw 2330, a second nut 2340, a second drive member 2350, and a second pressing block 2360. The second mounting plate 2320 is mounted on the second base plate 2100. The second lead screw 2330 passes through the second mounting plate 2320. The second nut 2340 is sleeved on the second lead screw 2330 and threadedly connected to it. The second nut 2340 is also connected to the second mounting plate 2320. The second drive member 2350 is fixed to one end of the second lead screw 2330. The second pressing block 2360 is connected to the other two ends of the second drive member 2350. The second drive member 2350 is configured to drive the second pressing block 2360 to move along the axial direction of the second lead screw 2330 towards the second fixed plate 2200 to press the battery cell. This second drive assembly 2300 has a simple structure and is easy to assemble and operate.

[0063] For example, the second drive element 2350 is a handwheel to facilitate manual operation by the operator. In another embodiment, the second drive element 2350 is a rotary motor, which is beneficial for achieving automated control.

[0064] The battery module fixture 2000 also includes a second limiting plate 2400, a third limiting plate 2500, and a limiting drive assembly 2600. The second limiting plate 2400 extends along a second direction and is disposed between the second drive assembly 2300 and the second fixing plate 2200. The second limiting plate 2400 has a first clearance position 2410, which corresponds to the first workstation 2110 and / or the second workstation 2120. The third limiting plate 2500 is parallel to and spaced apart from the second limiting plate 2400. The second limiting plate 2400, the third limiting plate 2500, the second fixing plate 2200, and the second drive assembly 2300 together form a... The second accommodating space for accommodating the battery cell assembly has the bottom and top of the battery cell abutting against the second limiting plate 2400 and the third limiting plate 2500, respectively. The third limiting plate 2500 is provided with a second clearance position 2510, which corresponds to the first station 2110 and / or the second station 2120. The third limiting plate 2500 is connected to the output end of the limiting drive assembly 2600, which is configured to drive the third limiting plate 2500 to move closer to or further away from the second limiting plate 2400.

[0065] The second limiting plate 2400 and the third limiting plate 2500 can limit the top and bottom of the battery cell, that is, limit the top and bottom of the battery module. The limiting drive component 2600 can drive the third limiting plate 2500 to move closer to or away from the second limiting plate 2400, so that the bottom and top of each battery cell are in contact with the second limiting plate 2400 and the third limiting plate 2500, thereby improving the consistency of the position of multiple battery cells and improving the structural stability of the battery module. At the same time, since one side of the battery module is attached to the second bottom plate 2100, the consistency of multiple battery cells on this surface is higher under the action of gravity. When a liquid cooling plate needs to be installed on this surface, it helps to ensure the adhesion between the liquid cooling plate and the side of the battery cell, thereby improving the uniformity of heat conduction.

[0066] Meanwhile, the second limiting plate 2400 is provided with a first clearance position 2410 corresponding to the first station 2110 and / or the second station 2120, and the third limiting plate 2500 is provided with a second clearance position 2510 corresponding to the first station 2110 and / or the second station 2120, thereby avoiding interference between the second limiting plate 2400 and the third limiting plate 2500 and the first station 2110 or the second station 2120.

[0067] Furthermore, the first station 2110 is positioned closer to the second fixed plate 2200 than the second station 2120. The second limiting plate 2400 and the third limiting plate 2500 can be equipped with only the first clearance position 2410 and the second clearance position 2510 to avoid interference with the first station 2110, which helps to simplify the structure.

[0068] In one embodiment, the second drive assembly 2300 has a third clearance position 2310 configured to avoid the fixing band on the top of the welding cell to facilitate operator operation.

[0069] Specifically, the second extrusion block 2360 has a relief groove 2311, the second mounting plate 2320 and the second fixing plate 2200 have relief holes 2312, the relief holes 2312 and the relief groove 2311 together form a third relief position 2310, and the positions of the relief holes 2312 and the relief groove 2311 are set accordingly so that the operator can pass through the positions of the relief holes 2312 and the relief groove 2311 to realize the riveting and fixing strip.

[0070] The limit drive assembly 2600 includes a limit drive component 2610, a fixed base 2620, a limit rod 2630, a limit nut 2640, and a connector 2650. The connector 2650 is connected between the limit nut 2640 and the third limit plate 2500. The fixed base 2620 is disposed on the second mounting plate 2320. The limit drive component 2610 passes through the fixed base 2620 and is threadedly connected to the limit nut 2640. The limit drive component 2610 and the limit rod 2630 are located at the ends away from the third limit plate 2500, so that the limit drive component 2610 can push the third limit plate 2500 to move through the drive component.

[0071] Furthermore, the limit drive assembly 2600 also includes a third guide assembly 2660, which is disposed between the second base plate 2100 and the third limit plate 2500 to ensure the stability of the movement of the third limit plate 2500.

[0072] Furthermore, the third guide assembly 2660 includes a slider 2661 and a slide rail, wherein the slide rail is disposed on one of the third limiting plate 2500 and the second mounting plate 2320, and the slide rail extends along a first direction. The slider 2661 is slidably connected to the slide rail and connected to the other one, and the third limiting plate 2500 and the second mounting plate 2320 are connected to the other one. This third guide assembly 2660 helps to prevent jamming during the movement of the third limiting plate 2500.

[0073] In one embodiment, such as Figures 4 to 6 As shown, the battery pack fixture 1000 includes a first base plate 1100, a first fixed plate 1200, a movable plate 1300, and a first drive assembly 1400. The first fixed plate 1200 is disposed on the first base plate 1100. The movable plate 1300 is disposed parallel to and spaced apart from the first fixed plate 1200 along a first direction on the first base plate 1100. The space between the movable plate 1300 and the first fixed plate 1200 forms a first accommodating space for accommodating the battery pack. The output end of the first drive assembly 1400 is connected to the movable plate 1300, and the first drive assembly 1400 is used to drive the movable plate 1300 to move along a direction close to the first fixed plate 1200. During the battery pack assembly process, adjacent battery modules need to be fixed with adhesive. The sodium-ion battery processing equipment uses a first drive component 1400 to extrude multiple battery modules from the side of the battery module. This helps to ensure uniform thickness of the adhesive applied to the side of the battery module, balances the thermal resistance on the adhesive surface, improves the temperature uniformity of the side of the battery module, reduces the difference in thermal efficiency between different battery modules in the battery pack, and improves the service life and structural stability of the battery pack.

[0074] In addition, the battery pack fixture 1000 also includes a first limiting plate 1500 extending along a first direction. The first limiting plate 1500 is disposed on one side of the accommodating space along a second direction. The first limiting plate 1500 is used to limit the battery pack on one side along the second direction. The second direction is perpendicular to the first direction, thereby ensuring that multiple battery cell modules are located between the first fixed plate 1200 and the first movable plate 1300, so that the force of the first movable plate 1300 pushing the battery module can be evenly applied to the side of the battery module, and preventing any part of the battery module from being outside the first movable plate 1300.

[0075] Furthermore, the battery pack fixture 1000 also includes a moving auxiliary component 1600, which is arranged in an array on the first base plate 1100 to facilitate the side-pushing of the battery module into the first accommodating space. This moving auxiliary component 1600 improves the ease of battery module assembly.

[0076] Optionally, the moving auxiliary component 1600 is a ball, roller or pulley. The moving auxiliary component 1600 has a simple structure and is convenient for moving the battery module.

[0077] Since the battery module has a large size along the second direction, there are multiple first drive components 1400. These multiple first drive components 1400 are spaced apart along the second direction, so that they can jointly push the battery module at multiple positions, which helps to improve the uniformity of the adhesive between battery modules along the first direction.

[0078] In one embodiment, the first drive assembly 1400 includes a first mounting plate 1410, a first lead screw 1420, a first nut 1430, a first drive member 1440, and a first pressing block 1450. The first mounting plate 1410 is disposed on the first base plate 1100. The first lead screw 1420 passes through the first mounting plate 1410 and is connected to the movable plate 1300. The first nut 1430 is sleeved on the first lead screw 1420 and is threadedly connected to the first lead screw 1420. The first nut 1430 is connected to the first mounting plate 1410. The first driving member 1440 is fixed to one end of the first lead screw 1420. The first pressing block 1450 is connected to the other end of the first driving member 1440. The first driving member 1440 drives the first pressing block 1450 to move along the axial direction of the first lead screw 1420. When the first pressing block 1450 abuts against the movable plate 1300, the first pressing block 1450 can push the movable plate 1300 to move in the direction close to the first fixed plate 1200.

[0079] The first driving component 1440 drives the first lead screw 1420 to rotate, thereby pushing the first extrusion block 1450 to move along the first direction. The first extrusion block 1450 acts on the movable plate 1300 to push the movable plate 1300 to move along the first direction, thereby realizing the extrusion of the battery cell module.

[0080] Since there are multiple sets of first drive components 1400, the operator can first operate the first drive component 1400 located in the middle position, and then operate the first drive components 1400 located on both sides.

[0081] Since the first drive assembly 1400 drives the first pressing block 1450 to move, and then uses the first pressing block 1450 to push the movable plate 1300 to move, when the first drive member 1440 drives the first pressing block 1450 to move away from the first fixed plate 1200, the first pressing block 1450 separates from the movable plate 1300. When the first pressing block 1450 moves to the farthest position, the operator can manually pull the movable plate 1300 to a position away from the first fixed plate 1200.

[0082] The battery pack fixture 1000 also includes a first guide assembly 1700, which is disposed between the first mounting plate 1410 and the first pressing block 1450. The first guide assembly 1700 is configured to provide guidance for the movement of the first pressing block 1450. This first guide assembly 1700 helps to improve the stability of the movement of the first pressing block 1450 along a first direction.

[0083] Furthermore, the first mounting plate 1410 or the first pressing block 1450 is provided with a first guide hole. The first guide assembly 1700 includes a first guide rod 1710. One end of the first guide rod 1710 is connected to the first mounting plate 1410 or the first pressing block 1450 without the first guide hole, and the other end passes through the first guide hole, with the first guide rod 1710 slidably connected to the first guide hole. The first guide assembly 1700 utilizes the reciprocating motion of the first guide rod 1710 in the first guide hole, which helps to ensure the stability of the movement of the first pressing block 1450 and prevents the first pressing block 1450 from getting stuck.

[0084] The first guide assembly 1700 further includes a first limiting member 1720, which is disposed at the other end of the first guide rod 1710. The first limiting member 1720 and the first pressing block 1450 are respectively located on both sides of the first mounting plate 1410 and the first pressing block 1450 along a first direction. The first limiting member 1720 helps to prevent the first guide rod 1710 from dislodging from the first guide hole during the movement of the first pressing block 1450, thereby improving the safety of the first guide assembly 1700.

[0085] The battery pack fixture 1000 also includes a second guide assembly 1800, which is disposed between the first mounting plate 1410 and the movable plate 1300. The second guide assembly 1800 is configured to provide guidance for the movement of the movable plate 1300. This second guide assembly 1800 helps to improve the stability of the movable plate 1300's movement along a first direction.

[0086] Furthermore, the first mounting plate 1410 or the movable plate 1300 is provided with a second guide hole, and the second guide assembly 1800 includes a second guide rod 1810. One end of the second guide rod 1810 is connected to the first mounting plate 1410 or the movable plate 1300 without the first guide hole, and the other end passes through the second guide hole, with the second guide rod 1810 slidably connected to the second guide hole.
