Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a separator assembly and a supporting device. Background Art

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. In this case, electric vehicles have become an important component of the sustainable development of the automobile industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery technology is an important factor in their development.

[0003] The production process of battery cells includes a formation step, during which a tray is required to support the battery cells. Currently, the tray has poor adaptability to battery cells of different specifications. Utility Model Content

[0004] In view of the above problems, the present application provides a partition assembly and a supporting device, which can enhance the adaptability of the supporting device to battery cells of different specifications.

[0005] In a first aspect, the present application provides a partition assembly, which includes a first pressure plate, a second pressure plate and an adjustment mechanism, wherein the first pressure plate is used to place a battery cell, the second pressure plate is arranged opposite to the first pressure plate along the thickness direction of the first pressure plate, and the adjustment mechanism is arranged between the first pressure plate and the second pressure plate, and the adjustment mechanism is used to adjust the distance between the first pressure plate and the second pressure plate.

[0006] In this way, when multiple partition assemblies are arranged at intervals, since the battery cell is located between the first pressure plate of one of the partition assemblies and the second pressure plate of another partition assemblies, the gap between two adjacent partition assemblies can be adjusted by adjusting the distance between the first pressure plate and the second pressure plate through the adjustment mechanism. Therefore, the adjustment mechanism can reduce the gap to clamp the battery cell or increase the gap to loosen the battery cell, which is convenient for fixing the battery cell during formation and taking and placing the battery cell before and after formation. The partition assembly can be adjusted separately according to battery cells of different specifications, enhancing the adaptability of the supporting device to battery cells of different specifications. In addition, the partition assembly does not need to be repeatedly repaired, which improves production efficiency and reduces production costs.

[0007] In some embodiments, the adjustment mechanism includes an adjustment member and a transmission member connected to one end of the adjustment member, and the transmission member can drive the adjustment member to move relative to the first pressing plate and / or the second pressing plate in a thickness direction perpendicular to the first pressing plate to adjust the distance between the first pressing plate and the second pressing plate.

[0008] In this way, the movement of the transmission member drives the movement of the adjustment member, so that the distance between the first pressing plate and the second pressing plate can be adjusted, and then the gap between two adjacent partition assemblies can be adjusted to clamp or loosen the battery cell.

[0009] In some embodiments, the cross-section of the adjusting member decreases along the direction in which the adjusting member moves away from the transmission member, and when the adjusting member moves away from the transmission member, the distance between the first pressure plate and the second pressure plate increases; when the adjusting member moves toward the direction in which it approaches the transmission member, the distance between the first pressure plate and the second pressure plate decreases.

[0010] In this way, the distance between the first pressing plate and the second pressing plate can be adjusted by moving the adjusting member away from or close to the transmission member.

[0011] In some embodiments, the contact surface between the adjusting member and the first pressing plate and / or the second pressing plate is an inclined surface.

[0012] In this way, the contact area between the adjusting member and the first and second pressing plates can be increased, so that the first and second pressing plates are subjected to uniform force, and the first and second pressing plates can move stably along their own thickness directions, thereby improving the stability of battery cell production.

[0013] In some embodiments, the transmission member and the adjusting member are connected by threads, and when the transmission member rotates, the adjusting member is driven to move.

[0014] In this way, the transmission member and the adjusting member are connected by threads, and the rotation of the transmission member can be converted into the movement of the adjusting member along the axial direction of the transmission member, so as to adjust the distance between the first pressing plate and the second pressing plate.

[0015] In some embodiments, the partition assembly includes a mounting frame, the mounting frame is formed with a through hole, and the transmission member is inserted into the through hole.

[0016] In this way, the adjustment mechanism, the first pressing plate and the second pressing plate can be installed together through the mounting frame, which facilitates the installation and disassembly of the partition assembly, improves the efficiency of the installation and disassembly of the partition assembly, and thus improves the production efficiency of the battery cell.

[0017] In certain embodiments, the adjustment mechanism includes a bearing disposed in the through hole, an outer ring of the bearing is connected to a side wall of the through hole, and a transmission member is disposed through an inner ring of the bearing.

[0018] In this way, the bearing can reduce the friction generated by the rotation of the transmission member relative to the mounting frame, reduce the wear of the rotating member during rotation, and increase the service life of the rotating member.

[0019] In certain embodiments, the adjustment mechanism includes an end cap disposed on the mounting frame, the end cap at least partially pressing against the bearing.

[0020] In this way, the end cover presses against the bearing to prevent the bearing from moving axially along the through hole, so that the bearing is firmly fixed in the through hole, thereby improving the stability of the bearing.

[0021] In some embodiments, a loading rack is disposed on a side of the first pressing plate facing away from the second pressing plate, and the loading rack and the first pressing plate enclose a containing space, and the battery cells are located in the containing space.

[0022] In this way, the accommodating space is formed by the loading rack and the first pressing plate, and the battery cell can be fixed on the first pressing plate, so that the battery cell can be easily taken in and out.

[0023] In a second aspect, the present application provides a supporting device, which includes a tray assembly and a partition assembly, and the partition assembly is detachably connected to the tray assembly.

[0024] In this way, the tray device can apply restraint to the battery cell through the tray assembly and the separator assembly, that is, apply squeezing force to the battery cell, thereby suppressing the expansion of the shell of the battery cell during charging and discharging. Since the shell no longer expands, the bubbles generated in the shell are relatively easy to discharge, and the bubbles in the shell no longer grow larger, and it is not easy to bring out the electrolyte in the shell, thereby reducing the waste of electrolyte. The separator assembly and the tray assembly are detachably connected, which is convenient for replacing and repairing a single separator assembly, without the need to replace the entire support device, thereby reducing maintenance costs.

[0025] In some embodiments, the tray assembly includes a base, the base is formed with a receiving groove, and a plurality of partition assemblies are arranged in the receiving groove at intervals.

[0026] In this way, a plurality of partitioning components are arranged at intervals in the receiving groove, and the receiving groove can be divided into a plurality of spaces so as to accommodate a plurality of battery cells, thereby improving the production efficiency of the battery cells.

[0027] In some embodiments, the tray assembly includes a guide rod and a plurality of sliders slidably disposed on the guide rod, the plurality of sliders are arranged along the axial direction of the guide rod, and the partition assembly is disposed on the sliders.

[0028] In this way, the distance between two adjacent partition assemblies can be adjusted by sliding the slider on the guide rod, thereby applying or releasing the restraining force on the battery cell, with a simple structure and convenient operation.

[0029] In some embodiments, the slider is formed with a slot extending along the height direction of the base, and the partition assembly is detachably installed in the slot.

[0030] In this way, the partition assembly and the slider are detachably installed, so that the partition assembly can be quickly connected to the tray assembly or quickly removed from the tray assembly, and the gap size between two adjacent partition assemblies can be quickly adjusted to accommodate battery cells of different specifications.

[0031] In certain embodiments, the partition component is formed with a protrusion, and the protrusion is plug-fitted into the card slot.

[0032] In this way, by plugging and fitting the protrusion into the slot, the partition assembly and the tray assembly can be quickly disassembled and assembled, which facilitates replacement and repair of the partition assembly, while reducing the time for disassembly and assembly of the partition assembly and improving the production efficiency of the battery cell.

[0033] In some embodiments, one of the two adjacent sliders forms a limiting slot, and the other slider forms a limiting block, and the limiting block can slide in the limiting slot to limit the movement stroke of the entire slider.

[0034] In this way, the movement of the limiting block in the limiting groove can limit the moving distance between two adjacent sliders, and can also prevent the two adjacent sliders from being separated, so that the connection of the sliders is stable and reliable.

[0035] In some embodiments, the tray assembly includes a push plate connected to a slider located at an end portion, the push plate is slidably mounted on the guide rod, and the push plate, the slider and the base together form a receiving groove.

[0036] In this way, the push plate slides on the guide rod, which can push the slider to slide on the guide rod, thereby driving multiple partition components to move, thereby adjusting the distance between two adjacent partition components and achieving the clamping and loosening of the battery cell by the supporting device.

[0037] In some embodiments, the tray assembly includes a push rod, which connects the base and the push plate. The push rod can move relative to the base to push the push plate to move, thereby adjusting the distance between two adjacent partition assemblies.

[0038] In this way, by rotating the push rod, the push plate can be pushed to slide on the guide rod, so as to push the slider to slide on the guide rod, thereby driving multiple partition components to move, thereby adjusting the distance between two adjacent partition components and achieving the clamping and loosening of the battery cell by the supporting device.

[0058] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0059] In the present application, battery cells may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries or magnesium-ion batteries, etc., and the embodiments of the present application do not limit this. Battery cells may be cylindrical, flat, rectangular or other shapes, etc., and the embodiments of the present application do not limit this. Battery cells are generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells and soft-pack battery cells, and the embodiments of the present application do not limit this.

[0060] A battery cell includes an electrode assembly and an electrolyte. The electrode assembly includes a positive electrode sheet, a negative electrode sheet, and a separator. A battery cell mainly works by the movement of metal ions between the positive electrode sheet and the negative electrode sheet. The separator is used to be set between the positive electrode sheet and the negative electrode sheet to insulate the positive electrode sheet and the negative electrode sheet to avoid short circuit.

[0061] The battery cell also includes a shell and an end cover. The shell has an opening. The end cover covers the opening to form a closed space isolated from the external space. The closed space is used to accommodate the electrode assembly, electrolyte and other functional components.

[0062] The production process of battery cells includes a formation step, which refers to the chemical and electrochemical reaction process in which the green plate is converted to a charged state in the electrolyte through charging, impurities are removed, and the electrochemical activity of its active substances is improved. In the formation step, when the battery cell is charged and discharged, bubbles will be generated inside the battery cell, which will cause the shell of the battery cell to expand. The bubbles inside the battery cell are not easy to discharge. As the gas inside the battery cell increases, the bubbles gradually become larger. When the bubbles are large, the bubbles gradually rise inside the battery cell and eventually carry the electrolyte out of the battery cell, resulting in a waste of electrolyte.

[0063] During the formation step, a tray is required to support the battery cells. Currently, the tray has poor adaptability to battery cells of different specifications. The currently used tray is provided with a partition, and the battery cells are located between two partitions. The size of the partition is fixed, and the gap between two adjacent partitions needs to be changed by mold repair or gasketing, which affects production efficiency and increases production costs. In order to enhance the adaptability of the tray to battery cells of different specifications, the present application provides the following technical solutions.

[0064] Please refer to Figure 1-Figure 3 , Figure 1 It is a schematic diagram of the structure of a supporting device 1000 according to some embodiments of the present application; Figure 2 This is a schematic diagram of the structure of a partition assembly 100 according to some embodiments of the present application; Figure 3 for Figure 2 Cross-sectional view along the AA direction. The partition assembly 100 of the embodiment of the present application is used for a supporting device 1000, and the partition assembly 100 includes a first pressing plate 10, a second pressing plate 20 and an adjusting mechanism 30, wherein the first pressing plate 10 is used to place a battery cell 2000, the second pressing plate 20 is arranged opposite to the first pressing plate 10 along the thickness direction of the first pressing plate 10, and the adjusting mechanism 30 is arranged between the first pressing plate 10 and the second pressing plate 20, and the adjusting mechanism 30 is used to adjust the distance between the first pressing plate 10 and the second pressing plate 20.

[0065] Specifically, the partition assembly 100 is a component with a partitioning function, and multiple partition assemblies 100 divide multiple spaces for accommodating battery cells 2000. For example, a gap is formed between two adjacent partition assemblies 100, and the gap is used to accommodate the battery cell 2000, that is, a space for accommodating the battery cell 2000 is formed between two adjacent partition assemblies 100.

[0066] The first pressing plate 10 and the second pressing plate 20 may be rectangular plate-shaped structures, and the sizes of the first pressing plate 10 and the second pressing plate 20 may be larger than the size of the battery cell 2000 .

[0067] The adjustment mechanism 30 is a structure for adjusting the positions of the first pressure plate 10 and the second pressure plate 20. The adjustment mechanism 30 can increase the gap between two adjacent partition assemblies 100 or reduce the gap between two adjacent partition assemblies 100 by adjusting the positions of the first pressure plate 10 and the second pressure plate 20.

[0068] In this way, when multiple partition assemblies 100 are arranged at intervals, since the battery cell 2000 is located between the first pressing plate 10 of one partition assembly 100 and the second pressing plate 20 of another partition assembly 100, the gap between two adjacent partition assemblies 100 can be adjusted by adjusting the distance between the first pressing plate 10 and the second pressing plate 20 through the adjustment mechanism 30. Therefore, the adjustment mechanism 30 can reduce the gap to clamp the battery cell 2000 or increase the gap to loosen the battery cell 2000, which is convenient for fixing the battery cell 2000 during formation and taking and placing the battery cell 2000 before and after formation. The partition assembly 100 can be adjusted separately according to the battery cells 2000 of different specifications, enhancing the adaptability of the supporting device 1000 to the battery cells 2000 of different specifications. In addition, the partition assembly 100 does not need to be repeatedly repaired, which improves production efficiency and reduces production costs.

[0069] Please refer to Figure 3 In some embodiments, the adjustment mechanism 30 includes an adjustment member 31 and a transmission member 32 connected to one end of the adjustment member 31. The transmission member 32 can drive the adjustment member 31 to move relative to the first pressing plate 10 and / or the second pressing plate 20 along a thickness direction perpendicular to the first pressing plate 10 to adjust the distance between the first pressing plate 10 and the second pressing plate 20.

[0070] Specifically, the transmission member 32 can be a circular shaft, and a first inner hole 33 can be formed at one end of the transmission member 32 away from the adjusting member 31. The shape of the first inner hole 33 can be hexagonal. By rotating the hexagonal wrench in the first inner hole 33, the transmission member 32 can be rotated along its own central axis to drive the adjusting member 31 to move.

[0071] The adjusting member 31 can move relative to the first pressing plate 10 in a thickness direction perpendicular to the first pressing plate 10 , can also move relative to the second pressing plate 20 in a thickness direction perpendicular to the first pressing plate 10 , or can also move relative to both the first pressing plate 10 and the second pressing plate 20 in a thickness direction perpendicular to the first pressing plate 10 .

[0072] In this way, the movement of the transmission member 32 drives the adjustment member 31 to move, so as to adjust the distance between the first pressing plate 10 and the second pressing plate 20 , and further adjust the gap between two adjacent partition assemblies 100 , so as to clamp or loosen the battery cell 2000 .

[0073] Please refer to Figure 3 In some embodiments, as the adjusting member 31 moves away from the transmission member 32, the cross-section of the adjusting member 31 becomes smaller. When the adjusting member 31 moves away from the transmission member 32, the distance between the first pressure plate 10 and the second pressure plate 20 becomes larger. When the adjusting member 31 moves toward the transmission member 32, the distance between the first pressure plate 10 and the second pressure plate 20 becomes smaller.

[0074] Specifically, the cross section of the adjusting member 31 may be rectangular, and along the direction in which the adjusting member 31 moves away from the transmission member 32, the length of the cross section of the adjusting member 31 may remain unchanged, and the width may decrease, or the length and width of the cross section of the adjusting member 31 may decrease simultaneously. The distance between the first pressing plate 10 and the second pressing plate 20 may be the width of the cross section of the adjusting member 31.

[0075] In this way, the distance between the first pressing plate 10 and the second pressing plate 20 can be adjusted by moving the adjusting member 31 away from or close to the transmission member 32 .

[0076] Please refer to Figure 3 In some embodiments, the contact surface between the adjusting member 31 and the first pressing plate 10 and / or the second pressing plate 20 is an inclined surface.

[0077] Specifically, the contact surface between the adjusting member 31 and the first pressing plate 10 may be an inclined surface, the contact surface between the adjusting member 31 and the second pressing plate 20 may be an inclined surface, or the contact surface between the adjusting member 31 and the first pressing plate 10 and the second pressing plate 20 may be both inclined surfaces. The degree of inclination of the inclined surface may be set according to actual needs.

[0078] In this way, the contact area between the adjusting member 31 and the first pressing plate 10 and the second pressing plate 20 can be increased, so that the first pressing plate 10 and the second pressing plate 20 are subjected to uniform force, so that the first pressing plate 10 and the second pressing plate 20 can move stably along their own thickness direction, thereby improving the stability of the production of the battery cell 2000.

[0079] In some embodiments, the transmission member 32 is connected to the adjusting member 31 through threads, and when the transmission member 32 rotates, the adjusting member 31 is driven to move.

[0080] Specifically, a thread may be formed on one end of the transmission member 32 close to the adjusting member 31, and the thread may be a triangular thread, a rectangular thread, a trapezoidal thread, a sawtooth thread, etc. A first threaded hole 34 may be formed on one end of the adjusting member 31 close to the transmission member 32, and the thread of the transmission member 32 is screwed into the first threaded hole 34. The thread may be a left-hand thread or a right-hand thread. When the thread is a right-hand thread, the transmission member 32 rotates counterclockwise, and the adjusting member 31 moves close to the transmission member 32. When the transmission member 32 rotates clockwise, the adjusting member 31 moves away from the transmission member 32.

[0081] In this way, the transmission member 32 and the adjusting member 31 are connected by threads, and the rotation of the transmission member 32 can be converted into the axial movement of the adjusting member 31 along the transmission member 32, so as to adjust the distance between the first pressing plate 10 and the second pressing plate 20.

[0082] Please refer to Figure 3 and Figure 4 , Figure 4 for Figure 3 In some embodiments, the partition assembly 100 includes a mounting frame 40 , the mounting frame 40 is formed with a through hole 41 , and the transmission member 32 is disposed in the through hole 41 .

[0083] Specifically, the mounting frame 40 may be rectangular in shape, the first pressing plate 10 and the second pressing plate 20 may be mounted on the mounting frame 40, and the movement range of the first pressing plate 10 and the second pressing plate 20 may be limited by providing a limiter 237 on the mounting frame 40. The through hole 41 may be circular in shape, the transmission member 32 passes through the through hole 41 and is connected to the adjustment member 31, and the transmission member 32 and the adjustment member 31 are located between the first pressing plate 10 and the second pressing plate 20.

[0084] In this way, the adjustment mechanism 30 , the first pressing plate 10 and the second pressing plate 20 can be installed together through the mounting frame 40 , which facilitates the installation and disassembly of the partition assembly 100 , improves the efficiency of the assembly and disassembly of the partition assembly 100 , and thus improves the production efficiency of the battery cell 2000 .

[0085] Please refer to Figure 3 and Figure 4 In some embodiments, the adjustment mechanism 30 includes a bearing 35 disposed in the through hole 41 , an outer ring 36 of the bearing 35 is connected to the side wall of the through hole 41 , and the transmission member 32 is passed through an inner ring 37 of the bearing 35 .

[0086] Specifically, the bearing 35 may be a rolling bearing 35 , the outer ring 36 of the bearing 35 may be connected to the side wall of the through hole 41 to play a supporting role, and the inner ring 37 of the bearing 35 may cooperate with the transmission member 32 and rotate with the transmission member 32 .

[0087] In this way, the bearing 35 can reduce the friction generated by the rotation of the transmission member 32 relative to the mounting bracket 40, reduce the wear of the rotating member during rotation, and increase the service life of the rotating member.

[0088] Please refer to Figure 3 and Figure 4 In some embodiments, the adjustment mechanism 30 includes an end cover 38 disposed on the mounting frame 40 , and the end cover 38 at least partially presses against the bearing 35 .

[0089] Specifically, the shape of the end cover 38 may be circular, the outer diameter of the end cover 38 may be larger than the outer diameter of the bearing 35, and the inner diameter of the end cover 38 may be smaller than the outer diameter of the bearing 35, so that the end cover 38 may abut against the upper surface of the bearing 35. The inner diameter of the end cover 38 may be larger than the diameter of the circumscribed circle of the first inner hole 33, so that the hexagonal wrench may pass through the end cover 38 and be inserted into the first inner hole 33.

[0090] In this way, the end cover 38 presses against the bearing 35 to prevent the bearing 35 from moving axially along the through hole 41 , so that the bearing 35 is firmly fixed in the through hole 41 , thereby improving the stability of the bearing 35 .

[0091] Please refer to Figure 5-Figure 7 , Figure 5-Figure 7 The structure diagram of the partition assembly 100 of some embodiments of the present application is shown in FIG. 1. In some embodiments, a loading rack 11 is disposed on the side of the first pressing plate 10 away from the second pressing plate 20 , and the loading rack 11 and the first pressing plate 10 enclose a receiving space 12 , in which the battery cell 2000 is located.

[0092] Specifically, the loading rack 11 may be composed of two first side plates 13 and a first bottom plate 14, the first side plates 13 and the first bottom plate 14 are arranged vertically, the distance between the two first side plates 13 may be consistent with the length of the battery cell 2000, and the width of the first bottom plate 14 may be consistent with the width of the battery cell 2000. The two first side plates 13 may extend in a direction close to each other to form a flange 15, and the flange 15 allows the battery cell 2000 to be firmly fixed in the accommodating space 12. The loading rack 11 may be mechanically connected to the first pressing plate 10, or may be integrally formed.

[0093] In this way, the accommodating space 12 is formed by the loading frame 11 and the first pressing plate 10 , and the battery cell 2000 can be fixed on the first pressing plate 10 , so that the battery cell 2000 can be easily taken in and out.

[0094] Please refer to Figure 1 and Figure 8 , Figure 8 Schematic diagram of the structure of the tray assembly 200 of some embodiments of the present application. The carrying device 1000 of the embodiment of the present application comprises a tray assembly 200 and a partition assembly 100, and the partition assembly 100 is detachably connected to the tray assembly 200.

[0095] Specifically, the tray assembly 200 can apply a restraining force to the battery cell 2000 and ensure the restraining time after the battery cell 2000 is placed therein, and the partition assembly 100 can play a supporting and adjusting role when the tray assembly 200 pressurizes the battery cell 2000.

[0096] In this way, the tray device can apply restraint to the battery cell 2000 through the tray assembly 200 and the separator assembly 100, that is, apply a squeezing force to the battery cell 2000, thereby suppressing the shell expansion phenomenon of the battery cell 2000 during charging and discharging. Since the shell no longer expands, the bubbles generated in the shell are relatively easy to discharge, and the bubbles in the shell no longer grow larger, and it is not easy to bring out the electrolyte in the shell, thereby reducing the waste of electrolyte. The separator assembly 100 is detachably connected to the tray assembly 200, which is convenient for replacing and repairing a single separator assembly 100, without the need to replace the entire supporting device 1000, thereby reducing maintenance costs.

[0097] Please refer to Figure 1 and Figure 8 In some embodiments, the tray assembly 200 includes a base 210 , the base 210 is formed with a receiving groove 211 , and a plurality of partition assemblies 100 are arranged in the receiving groove 211 at intervals.

[0098] Specifically, the base 210 is a load-bearing component of the tray assembly 200. The base 210 can be formed by connecting a second bottom plate 212 and two second side plates 213. The two second side plates 213 are arranged perpendicular to the second bottom plate 212. The upper surface of the second bottom plate 212 can support multiple battery cells 2000. The second bottom plate 212 and the second side plates 213 together form a receiving groove 211. The partition assembly 100 can be arranged parallel to the second side plate 213. Multiple partition assemblies 100 can divide the receiving groove 211 into multiple spaces for accommodating battery cells 2000. When the number of the partition assemblies 100 is seven, the receiving groove 211 can accommodate eight battery cells 2000.

[0099] In this way, a plurality of partition assemblies 100 are disposed at intervals in the receiving groove 211 , and the receiving groove 211 can be divided into a plurality of spaces so as to accommodate a plurality of battery cells 2000 , thereby improving the production efficiency of the battery cells 2000 .

[0100] Please refer to Figure 1 In some embodiments, the tray assembly 200 includes a guide rod 220 and a plurality of sliders 230 slidably disposed on the guide rod 220 , the plurality of sliders 230 are arranged along the axial direction of the guide rod 220 , and the partition assembly 100 is disposed on the slider 230 .

[0101] Specifically, the cross section of the guide rod 220 may be circular or rectangular. The number of guide rods 220 may be two, four, etc., and the plurality of guide rods 220 are arranged radially along the guide rod 220. The slider 230 may be a plate-like structure, and a slide groove 231 is formed on the slider 230. The slider 230 is inserted into the guide rod 220 through the slide groove 231, and the slider 230 can move along the axial direction of the guide rod 220. When the number of guide rods 220 is two, the sliders 230 on the two guide rods 220 are arranged one by one, and the number of sliders 230 on each guide rod 220 may be 11, 12, or 13, etc., and the partition assembly 100 is arranged between the two opposing sliders 230.

[0102] In this way, by sliding the slider 230 on the guide rod 220, the distance between two adjacent partition assemblies 100 can be adjusted, so as to apply or release the restraining force on the battery cell 2000, with a simple structure and convenient operation.

[0103] Please refer to Figure 1 and Figure 8 In some embodiments, the slider 230 is formed with a slot 232 , which extends along the height direction of the base 210 , and the partition assembly 100 is detachably installed in the slot 232 .

[0104] Specifically, the extending direction of the slot 232 may be the length direction of the slot 232, or the direction in which the partition assembly 100 is inserted into the slot 232. The slot 232 is formed on the side of the slider 230 facing the partition assembly 100, and the cross section of the slot 232 may be rectangular or trapezoidal, and the partition assembly 100 may be inserted into or removed from the slot 232.

[0105] In this way, the partition assembly 100 and the slider 230 are detachably installed, so that the partition assembly 100 can be quickly connected to the tray assembly 200 or quickly removed from the tray assembly 200, and the gap size between two adjacent partition assemblies 100 can be quickly adjusted to accommodate battery cells 2000 of different specifications.

[0106] Please refer to Figure 5 and Figure 8 In some embodiments, the partition assembly 100 is formed with a protrusion 50 , and the protrusion 50 is plug-fitted with the slot 232 .

[0107] Specifically, the mounting frame 40 extends outwardly in a direction perpendicular to the thickness of the mounting frame 40 to form a protrusion 50, the cross section of the protrusion 50 may be rectangular or trapezoidal, the length direction of the protrusion 50 may be the length direction of the slot 232, and the thickness direction of the protrusion 50 may be the thickness direction of the partition assembly 100. The number of protrusions 50 on the partition assembly 100 may be two, and the two protrusions 50 are respectively inserted into two oppositely arranged slots 232 to limit the movement of the partition assembly 100 along the thickness direction of the partition assembly 100.

[0108] In this way, by plugging and fitting the protrusion 50 into the slot 232 , the partition assembly 100 and the tray assembly 200 can be quickly disassembled and assembled, which facilitates replacement and repair of the partition assembly 100 , while reducing the disassembly and assembly time of the partition assembly 100 and improving the production efficiency of the battery cell 2000 .

[0109] Please refer to Figure 8 In some embodiments, among two adjacent sliders 230 , one slider 230 forms a limiting groove 233 , and the other slider 230 forms a limiting block 234 , and the limiting block 234 can slide in the limiting groove 233 to limit the movement range of the entire slider 230 .

[0110] Specifically, one of the sliders 230 forms a limiting groove 233, and the other slider 230 forms a limiting block 234. It can also be understood that the limiting groove 233 and the limiting block 234 are respectively located on both sides of the same slider 230 along the thickness direction of the partition assembly 100. The limiting block 234 of one slider 230 can be engaged with the limiting groove 233 of the other slider 230 to connect the two sliders 230 together. The limiting groove 232 can be a T-shaped groove, and the limiting block 234 can be T-shaped.

[0111] The limiting groove 233 includes a first wall surface 235 and a second wall surface 236 which are arranged opposite to each other along the thickness direction of the partition assembly 100. The limiting block 234 includes a limiting portion 237 which is used to be accommodated in the limiting groove 233 and constrained between the first wall surface 235 and the second wall surface 236. The length of the limiting portion 237 is less than the distance between the first wall surface 235 and the second wall surface 236. The first wall surface 235 and the second wall surface 236 are wall surfaces in the limiting groove 233 which are used to abut against the limiting block 234 to limit the distance between the two adjacent sliders 230 and the distance between the two adjacent sliders 230. Optionally, the first wall surface 235 is a wall surface in the limiting groove 233 which is used to abut against the limiting portion 237 to prevent the two adjacent sliders 230 from being separated. The second wall surface 236 is a wall surface in the limiting groove 233 which is used to abut against the limiting portion 237 to limit the minimum distance between the two adjacent sliders 230.

[0112] In this way, by the movement of the limiting block 234 in the limiting groove 233 , the moving distance between two adjacent sliders 230 can be limited, and the separation of two adjacent sliders 230 can be avoided, so that the connection of the sliders 230 is stable and reliable.

[0113] Please refer to Figure 8 In some embodiments, the tray assembly 200 includes a push plate 240 connected to a slider 230 located at an end portion, the push plate 240 is slidably mounted on the guide rod 220, and the push plate 240, the slider 230 and the base 210 together form a receiving groove 211.

[0114] Specifically, the push plate 240 can be a plate-like structure of a regular shape such as a circle or a rectangle, or can be a plate-like structure of an irregular shape. The push plate 240 can be fixedly connected to the slider 230, or can be integrally formed. The push plate 240 is perpendicular to the slider 230 and the second bottom plate 212, and the volume of the accommodating groove 211 can change with the movement of the push plate 240. When the push plate 240 moves close to the slider 230, the volume of the accommodating groove 211 becomes smaller, which is convenient for clamping the battery cell 2000; when the push plate 240 moves away from the slider 230, the volume of the accommodating groove 211 becomes larger, which is convenient for taking and placing the battery cell 2000.

[0115] In this way, the push plate 240 slides on the guide rod 220, which can push the slider 230 to slide on the guide rod 220, thereby driving multiple partition assemblies 100 to move, thereby adjusting the distance between two adjacent partition assemblies 100, and realizing the clamping and loosening of the battery cell 2000 by the supporting device 1000.

[0116] Please refer to Figure 1 In some embodiments, the tray assembly 200 includes a push rod 250 , which connects the base 210 and the push plate 240 . The push rod 250 can move relative to the base 210 to push the push plate 240 to move, thereby adjusting the distance between two adjacent partition assemblies 100 .

[0117] Specifically, the push rod 250 can be a screw rod, and the second side plate 213 can be formed with a second threaded hole 214. The push rod 250 is inserted into the second threaded hole 214, and the thread can be a right-hand thread. When the push rod 250 rotates clockwise relative to the second side plate 213, the push plate 240 moves closer to the slider 230, and the gap between the two adjacent partition components 100 is reduced; when the push rod 250 rotates counterclockwise relative to the second side plate 213, the push plate 240 moves away from the slider 230, and the gap between the two adjacent partition components 100 is increased.

[0118] A second inner hole 251 may be formed at one end of the push rod 250 away from the push plate 240. The shape of the second inner hole 251 may be hexagonal. By rotating the hexagonal wrench in the second inner hole 251, the push rod 250 can be rotated along its own central axis to drive the push plate 240 to move.

[0119] In this way, by rotating the push rod 250, the push plate 240 can be pushed to slide on the guide rod 220, so as to push the slider 230 to slide on the guide rod 220, thereby driving multiple partition assemblies 100 to move, thereby adjusting the distance between two adjacent partition assemblies 100, and realizing the clamping and loosening of the battery cell 2000 by the supporting device 1000.

[0120] The application process of the supporting device 1000 of the embodiment of the present application can be as follows: before the formation begins, the battery cell 2000 is placed in the accommodating space 12 of the partition assembly 100, and the push rod 250 is rotated to push the push plate 240 to slide close to the slider 230 to push the slider 230 to slide, thereby driving the partition assembly 100 to move. When the limiting portion 237 of the slider 230 abuts against the second wall 236 of the limiting groove 233 of another slider 230, the transmission member 32 is rotated according to the thickness of the battery cell 2000, driving the adjustment member 31 to move in the direction away from the transmission member 32, adjusting the distance between the first pressure plate 10 and the second pressure plate 20, thereby adjusting the gap between the two adjacent partition assemblies 100, and then applying appropriate restraint force to the battery cell 2000.

[0121] After the formation is completed, the push rod 250 is rotated to drive the push plate 240 to slide away from the slider 230, and then drive the slider 230 to slide, thereby driving the partition assembly 100 to move to release the restraining force on the battery cell 2000. When the limiting portion 237 of the slider 230 abuts against the first wall 235 of the limiting groove 233 of another slider 230, the transmission member 32 is rotated to drive the adjustment member 31 to move in the direction close to the transmission member 32, and then the battery cell 2000 is removed from the partition assembly 100.
