Description

Technical Field

[0001] The embodiments of the present application relate to the field of battery technology, and in particular to a shelf device and a battery production line. Background Art

[0002] This section is intended to provide a background or context for the embodiments of the present application. No description herein is admitted to be prior art by virtue of its inclusion in this section.

[0004] Taking battery cells as an example, during the preparation of battery cells, gas may be generated due to decomposition of electrolyte and other reasons. The gas generated by the battery cells accumulates inside the battery cells, which may lead to a decrease in the quality of the battery cells. In the existing production line, the battery cells are vented by the formation machine, but the venting effect is not ideal. Utility Model Content

[0005] In view of this, the embodiments of the present application hope to provide a shelf device and a battery production line that can improve the problem of unsatisfactory exhaust effect of battery cells.

[0006] An embodiment of the utility model provides a shelf device, which includes: a shelf having one or more placement spaces, wherein the placement spaces are used to place a tray device loaded with battery monomers; one or more exhaust mechanisms, at least one of the placement spaces is equipped with the exhaust mechanism, and the exhaust mechanism is used to exhaust the battery monomers during the placement of the tray device, wherein the exhaust mechanism includes: at least one exhaust unit having a suction nozzle; a carrier for carrying the tray device; and a first drive member for driving the carrier to move in a height direction so that the battery monomers loaded on the tray device can be docked with or separated from the suction nozzle.

[0007] In the present embodiment, an exhaust mechanism is provided on the shelf, so that the battery cells can be exhausted while they are loaded on the pallet device and placed on the shelf, rather than being limited to exhausting the battery cells during the formation treatment. In this way, the accumulation of gas generated in the battery cells during periods other than the formation treatment can be reduced, thereby improving the quality of the battery cells.

[0008] In some embodiments, at least one side of the placement space along a first direction is open to allow the tray device to enter or leave the placement space, and the first direction intersects with the height direction.

[0009] In this way, the placement and removal of the pallet device can be facilitated, and the manufacturing cost of the shelf device can also be reduced.

[0010] In some embodiments, there are multiple placement spaces, and at least a portion of the multiple placement spaces are distributed along the height direction; and / or at least a portion of the multiple placement spaces are distributed along the second direction, and the second direction intersects with the height direction.

[0011] In this way, the load capacity of the shelf device can be increased.

[0012] In some embodiments, the exhaust mechanism includes a base, a top seat and a plurality of connecting rods, the top seat is located on the top side of the base, and the two are connected by the connecting rods, the supporting member is located between the top seat and the base, and the exhaust unit is arranged on the top seat.

[0013] In this way, the top seat, the base and the connecting rod actually form a frame structure, and the exhaust unit, the bearing parts, etc. are integrated in the frame structure. Therefore, in the actual assembly process, it is only necessary to assemble the frame structure into the placement space, which simplifies the operation.

[0014] In some embodiments, the first driving member includes a cylinder, and the cylinder includes a cylinder barrel and a cylinder rod. The top end of the cylinder barrel is connected to the top seat, and the bottom end of the cylinder rod is connected to the supporting member.

[0015] In this way, the cylinder barrel and the exhaust unit are both arranged on the top seat, which is convenient for arranging the gas pipeline and makes the overall layout of the exhaust mechanism more compact.

[0016] In some embodiments, one of the carrier and the top seat has a limit rod extending in the height direction, and the limit rod is used to abut against the other of the carrier and the top seat when the battery cell is docked with the suction nozzle to prevent the carrier from continuing to move toward the suction nozzle.

[0017] In this way, it is possible to avoid the battery cell and the nozzle from being squeezed against each other and causing damage.

[0018] In some embodiments, the supporting member has a connecting groove, the connecting rod is inserted into the connecting groove, and the two are slidably matched along the height direction.

[0019] In this way, the connecting rod can guide the bearing member when it moves in the height direction, so that the bearing member moves more smoothly.

[0020] In some embodiments, the exhaust mechanism includes a plurality of support columns, which are disposed on the base and extend in a height direction, the support member having a hollow portion and a support surface for supporting a tray device, and when the support member is in an initial position, the top end of the support column passes through the hollow portion and is higher than the support surface, so that each of the support columns is used to support the tray device when the support member is in an initial position.

[0021] In this way, when placing the tray device, it can be positioned to a certain extent with the help of the support columns, without having to place it directly on the carrier, thereby simplifying the operation.

[0022] In some embodiments, the tray device enters or leaves the placement space along a first direction, at least a portion of the support columns are arranged on opposite sides of the base along a second direction, the top side surfaces of the support columns have a guide surface and a placement surface, the guide surface is inclined toward the tray device from the top side to the bottom side, the placement surface is connected to the bottom side of the guide surface and is horizontally arranged, the guide surface is used to guide the tray device to slide to the placement surface, the first direction intersects with the second direction and are respectively perpendicular to the height direction.

[0023] Thus, when the tray device enters the placement space along the first direction, the guide surface of the support column can correct the position deviation of the tray device in the second direction, so that the support column can automatically slide to the placement surface, thereby simplifying the operation. On the other hand, it can also improve the positioning accuracy of the tray device, facilitating the subsequent exhaust operation.

[0024] In some embodiments, a positioning pin is disposed on the top surface of the carrier, and the positioning pin is used to be inserted into a pin hole on the bottom side of the tray device along the height direction.

[0025] In this way, the tray device can be positioned more accurately.

[0026] In some embodiments, the exhaust unit includes: a mounting seat, which extends along a first direction, an exhaust duct, which is arranged on the mounting seat; and a plurality of suction nozzles distributed along the first direction, which are arranged on the mounting seat and connected to the exhaust duct, wherein the mounting seat is connected to the top seat and can slide relative to the top seat along the first direction, and the first direction intersects with the height direction.

[0027] In this way, the exhaust unit can simultaneously exhaust multiple battery cells distributed along the first direction, and the exhaust unit and the top seat can be installed and disassembled by sliding the mounting seat along the first direction, which is convenient for maintenance. In addition, the relative position of the suction nozzle and the battery cell along the first direction can be adjusted by sliding the mounting seat along the first direction, which is convenient for adapting to different models of battery trays, battery cells, etc.

[0028] In some embodiments, the exhaust mechanism includes a movable frame and a second driving member, the movable frame is mounted to the top seat, the mounting seat is connected to the movable frame, and the second driving member is used to drive the movable frame to move along a second direction to drive the mounting seat to move along the second direction, and the first direction intersects with the second direction and is perpendicular to the height direction respectively.

[0029] In this way, the position of the exhaust unit can be adjusted in the second direction to accommodate battery cells of different models.

[0048] Below, this application is described in detail.

[0049] The shelf device and battery production line provided in the embodiments of the present application are both used for the production of batteries. In order to make the shelf device and battery production line of the present application clearer, the batteries targeted by the present application are first introduced before describing the shelf device and battery production line of the present application.

[0050] The battery targeted by the embodiments of the present application can be used alone. Multiple batteries can also be grouped together and used as a battery pack. Batteries and battery packs can be used in, but are not limited to, electrical devices. Electrical devices include, but are not limited to, mobile phones, tablets, laptops, electric toys, electric tools, vehicles, ships, or spacecraft, etc. Among them, spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0051] Taking the electrical device as a vehicle as an example, the vehicle can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery is arranged inside the vehicle, and the battery can be arranged at the bottom of the vehicle or at the front or rear of the vehicle. The battery can be used to power the vehicle, for example, the battery can be used as an operating power source for the vehicle. In some embodiments, the battery can not only be used as an operating power source for the vehicle, but also as a driving power source for the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0052] The battery may be a lithium-ion battery, a sodium-lithium-ion battery, a lithium metal battery, or a lithium-sulfur battery, etc., which is not limited in the embodiments of the present application.

[0053] The battery includes at least one battery cell. The battery cell is the energy storage component of the battery. The battery also includes a battery monitoring and management device for monitoring the power level of the battery cell.

[0054] In a battery, there can be multiple battery cells, which can be connected in series, in parallel, or in a hybrid connection. A hybrid connection means that multiple battery cells are connected in series and in parallel. Multiple battery cells can be directly connected in series, in parallel, or in a hybrid connection; of course, a battery can also be a battery module formed by connecting multiple battery cells in series, in parallel, or in a hybrid connection, and then multiple battery modules are connected in series, in parallel, or in a hybrid connection to form a whole.

[0055] In the embodiment of the present application, the battery cell may be a secondary battery cell, which refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0056] The battery cell may be a cylindrical battery cell, a prismatic battery cell or a battery cell of other shapes. The prismatic battery cell includes a square shell battery cell or a multi-prismatic battery cell, and the multi-prismatic battery cell is, for example, a hexagonal battery cell, etc., and the present application has no particular limitation.

[0057] The internal cavity of the battery cell is used to place the electrode assembly and the electrolyte. For example, the battery cell includes a shell, an electrode assembly and an electrolyte, and the electrode assembly and the electrolyte are placed in the shell. The shell is used to encapsulate components such as the electrode assembly and the electrolyte. The shell is provided with an injection hole, and the electrolyte is injected into the internal cavity through the injection hole. In addition, air can be evacuated through the injection hole to discharge the gas generated by the battery cell.

[0058] The battery cell of the embodiment of the present application may also include a switch valve, which is arranged at the injection hole, so as to realize the opening and closing of the internal cavity of the battery cell. The switch valve can be opened and closed under the action of external force, and the switch valve can be opened by pressing the external force. After the external force is removed, the switch valve can be closed by its own elasticity.

[0059] In the production process of battery cells, the battery cells need to be subjected to formation treatment, which refers to the process of charging the battery cells for the first time to activate the battery. In the process of forming the battery cells, open formation is generally adopted, that is, the switch valve is in an open state.

[0060] In the battery production line of the related art, the battery cells are usually exhausted during the formation process. However, during the production process of the battery cells, gas generation may occur continuously, and not just during the formation process. Therefore, the effect of exhausting the battery cells only during the formation process is not ideal.

[0061] In view of this, a first aspect of an embodiment of the present application provides a shelf device, including a shelf and one or more exhaust mechanisms. The shelf has one or more placement spaces, and the placement space is used to place a tray device loaded with battery cells. At least one placement space is configured with an exhaust mechanism, and the exhaust mechanism is used to exhaust the battery cells during the placement of the tray device. The exhaust mechanism includes at least one exhaust unit, a carrier, and a first drive member. The exhaust unit has a suction nozzle, the carrier is used to carry the tray device, and the first drive member is used to drive the carrier to move in the height direction so that the battery cells loaded on the tray device can dock with or separate from the suction nozzle.

[0062] It can be understood that during the production process of battery monomers, they will be loaded into pallet devices and circulated between various workstations. During the circulation, the pallet devices may be placed on shelves. In the above technical scheme, the battery monomers carried by the pallet device can be exhausted while being placed on the shelf, thereby reducing the accumulation of gases generated in the battery monomers during periods other than formation treatment, thereby improving the quality of the battery monomers.

[0063] Some embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0064] See also Figures 1 to 3 The shelf device provided in the embodiment of the present application includes a shelf 1, and the shelf 1 has one or more placement spaces 11, and the placement space 11 is used to place the tray device X loaded with battery monomers. The shelf device also includes one or more exhaust mechanisms 2, and at least one placement space 11 is equipped with an exhaust mechanism 2. The exhaust mechanism 2 includes: at least one exhaust unit 21, and the exhaust unit 21 has a suction nozzle 211; a carrier 22 for carrying the tray device X, and a first driving member 23 for driving the carrier 22 to move in the height direction, so that the battery monomer carried by the tray device X can be docked with or separated from the suction nozzle 211.

[0065] The shelf 1 here can be a shelf for placing the tray device X at any position of the battery production line. In this embodiment, there is no limitation on its specific structure and specific position on the battery production line.

[0066] When the shelf 1 has a plurality of placement spaces 11, an exhaust mechanism 2 may be disposed in each placement space 11, or in only a portion of the placement spaces 11. One exhaust mechanism 2 may be disposed in each placement space 11, or multiple exhaust mechanisms 2 may be disposed simultaneously, without limitation.

[0067] The exhaust unit 21 may have one or more suction nozzles 211. Taking a battery cell as an example, the suction nozzle 211 may be connected to the injection hole of the battery cell and the switch valve of the battery cell may be opened, so that the gas in the internal cavity of the battery cell can be discharged with the help of the suction nozzle 211. The specific structure of the suction nozzle 211 may be determined according to the structure of the injection hole and the switch valve of the battery cell, and is not limited thereto.

[0068] There may be multiple exhaust units 21 , and the arrangement of the multiple exhaust units 21 may be determined according to the arrangement of the battery cells in the tray device X, which is not limited.

[0069] The supporting member 22 here can be a plate-like structure or a planar frame structure, and is arranged on the bottom side of the exhaust unit 21. The first driving member 23 can be a structure such as an electric cylinder, a pneumatic cylinder, an oil cylinder, etc., which can drive the supporting member 22 to move upward so that the battery cell is docked with the suction nozzle 211.

[0070] In the present embodiment, an exhaust mechanism 2 is provided on the shelf 1, so that the battery cells can be exhausted while they are loaded on the pallet device X and placed on the shelf 1, rather than being limited to exhausting the battery cells during the formation treatment. In this way, the accumulation of gas generated in the battery cells during periods other than the formation treatment can be reduced, thereby improving the quality of the battery cells.

[0071] Further, it can be understood that the suction nozzle 211 of the exhaust unit 21 needs to be connected to an external air extraction device (such as a vacuum pump) through a pipeline during actual use. In addition, the exhaust unit 21 may also need to be electrically connected to some external devices (such as an external control device) through a line. In this embodiment, the tray device X is moved with the help of the carrier 22 instead of moving the exhaust unit 21. That is, the exhaust unit 21 may not move in the height direction. In this way, on the one hand, it is convenient to arrange the above-mentioned pipelines and / or lines, and on the other hand, it can reduce the stretching, bending, movement, etc. of the above-mentioned pipelines and / or lines caused by the movement of the exhaust unit 21, thereby improving the use stability and service life of the above-mentioned pipelines and / or lines.

[0072] In some implementations, see Figure 1 At least one side of the placement space 11 is open along a first direction to allow the tray device X to enter or leave the placement space 11, and the first direction intersects with the height direction.

[0073] The first direction involved here and in the relevant parts below can be, for example, a horizontal direction (i.e., a direction perpendicular to the height direction), or a direction forming an acute angle or an obtuse angle with the height direction. The placement space 11 can be open on only one side along the first direction, or on both sides, without limitation.

[0074] In this way, it is convenient to place and take the tray device X, and the manufacturing cost of the shelf device can also be reduced. It should be noted that, unlike the formation cabinet used in the formation process, the shelf 1 only needs to be able to place the tray device X, and there is no need to provide some special environmental conditions for the tray device X (the accommodating space in the formation cabinet may need to be relatively sealed to provide the environmental conditions required for the formation, such as a negative pressure environment, etc.), therefore, opening at least one side of the placement space 11 along the first direction does not affect the function of the shelf 1.

[0075] Obviously, those skilled in the art may also provide an openable and closable door on the shelf 1 according to actual use requirements, so that the placement space 11 is in a relatively sealed state when the door is closed.

[0076] For some implementations, please refer to Figure 1 The number of the placement spaces 11 may be multiple, at least a portion of the multiple placement spaces 11 are distributed along the height direction, and / or at least a portion of the multiple placement spaces 11 are distributed along the second direction, and the second direction intersects with the height direction.

[0077] In this way, the loading capacity of the shelf device can be increased and the structure can be more compact.

[0078] The second direction mentioned here and in the relevant parts below may be perpendicular to the height direction, or may be at an acute angle or an obtuse angle to the height direction. Further, the first direction and the second direction may intersect and be respectively perpendicular to the height direction, or the first direction, the second direction, and the height direction may be mutually perpendicular, or the first direction, the second direction, and the height direction may intersect each other, wherein the first direction and the second direction are in the same plane, and the height direction may have an angle with the plane.

[0079] exist Figure 1 In the embodiment shown, the shelf 1 has three placement spaces 11 distributed along the height direction. In other embodiments, the shelf 1 may also have three placement spaces 11 distributed along the height direction. Figure 1 The rack device may include other placement spaces 11 distributed in the second direction, and / or have more or fewer placement spaces 11 distributed in the height direction. In this way, the carrying capacity of the rack device can be increased. The specific number and distribution of the placement spaces 11 can be determined according to the placement requirements in the actual production process, and there is no limitation on this.

[0080] In some implementations, see Figure 3-6 The exhaust mechanism 2 may include a base 25, a top seat 24 and a plurality of connecting rods 26. The top seat 24 is located on the top side of the base 25, and the two are connected by the connecting rods 26. The supporting member 22 is located between the top seat 24 and the base 25, and the exhaust unit 21 is arranged on the top seat 24.

[0081] In this way, the top seat 24, the base 25 and the connecting rod 26 actually form a frame structure, and the exhaust unit 21, the supporting member 22, etc. are integrated in the frame structure. Therefore, in the actual assembly process, it is only necessary to assemble the frame structure into the placement space 11, which simplifies the operation.

[0082] The specific structure and size of the base 25, the top seat 24 and the connecting rod 26 can be specifically determined according to the size of the placement space 11, the structure of the exhaust unit 21 and the structure of the carrier 22. One or more of the top seat 24, the base 25 and the connecting rod 26 can be fixedly connected to the wall of the placement space 11 (such as fixedly connected by a connection structure such as a bolt), or one or more of the top seat 24, the base 25 and the connecting rod 26 can be against the wall of the placement space 11 without being fixedly connected, or one or more of the top seat 24, the base 25 and the connecting rod 26 can be spaced from the wall of the placement space 11.

[0083] In some implementations, see Figure 4 The first driving member 23 may include a cylinder, and the cylinder may include a cylinder barrel 231 and a cylinder rod 232 , wherein the top end of the cylinder barrel 231 is connected to the top seat 24 , and the bottom end of the cylinder rod 232 is connected to the bearing member 22 .

[0084] In this way, the cylinder barrel 231 and the exhaust unit 21 are both arranged on the top seat 24, which is convenient for arranging the gas pipeline and makes the overall layout of the exhaust mechanism 2 more compact.

[0085] As an example, see Figure 5 During operation, the cylinder barrel 231 can drive the cylinder rod 232 to perform telescopic movement in the height direction, thereby driving the bearing member 22 to move in the height direction. A floating joint 221 can be provided on the top surface of the bearing member 22, and the cylinder rod 232 can be connected to the floating joint 221. Obviously, other connection structures can also be used to achieve the connection between the cylinder rod 232 and the bearing member 22, which is not limited to this.

[0086] There may be multiple first driving members 23 , for example, one or more first driving members 23 may be disposed on opposite sides of the top seat 24 along the second direction, so that the movement of the bearing member 22 along the height direction can be more stable.

[0087] In some implementations, see Figure 3 and Figure 5 One of the carrier 22 and the top seat 24 has a limiting rod 27 extending in the height direction, and the limiting rod 27 is used to abut against the other of the carrier 22 and the top seat 24 when the battery cell is docked with the suction nozzle 211 to prevent the carrier 22 from continuing to move toward the suction nozzle 211.

[0088] In this way, it is possible to avoid the battery cell and the suction nozzle 211 being squeezed against each other and thus being damaged.

[0089] exist Figure 3 and Figure 5 In the embodiment shown in FIG. 1 , a limiting rod 27 is provided on the top side surface of the carrier 22. When the battery cell is docked with the suction nozzle 211, one end of the limiting rod 27 abuts against the top seat 24, thereby preventing the carrier 22 from continuing to move toward the suction nozzle 211. Of course, the limiting rod 27 may also be provided on the bottom side surface of the top seat 24, or the limiting rod 27 may also be provided on both the carrier 22 and the top seat 24, and there is no limitation on this.

[0090] There may be multiple limiting rods 27 , for example, one or more limiting rods 27 may be provided on opposite sides of the top seat 24 and / or the bearing member 22 along the second direction to obtain a better limiting effect.

[0091] In some implementations, please refer to Figure 3 and Figure 5 The bearing member 22 has a connecting groove 222 , and the connecting rod 26 is inserted into the connecting groove 222 , and the two are slidably matched along the height direction.

[0092] In this way, the connecting rod 26 can guide the supporting member 22 when it moves in the height direction, so that the movement is more stable.

[0093] As an example, a linear bearing may be provided on the carrier 22, and the inner space of the linear bearing constitutes the above-mentioned connection groove 222. The advantage of the linear bearing is that it can reduce friction and improve the smoothness of movement. Obviously, the connection groove 222 that penetrates the carrier 22 in the height direction may also be directly provided on the carrier 22, and there is no limitation on this.

[0094] In some implementations, see Figure 3 , Figure 5 and Figure 6 The exhaust mechanism 2 includes a plurality of support columns 28, which are arranged on the base 25 and extend in the height direction. The carrier 22 has a hollow portion 223 and a bearing surface 224 for bearing the tray device X. When the carrier 22 is in the initial position, the top of the support column 28 passes through the hollow portion 223 and is higher than the bearing surface 224, so that each support column 28 is used to support the tray device X when the carrier 22 is in the initial position.

[0095] In this way, when the tray device X is placed, it can be positioned to a certain extent with the help of the support pillars 28, without having to place it directly on the carrier 22, thereby simplifying the operation.

[0096] As an example, the initial position here may be the lowest position of the carrier 22 in the height direction, at which the top of the support column 28 passes through the hollow portion 223 on the carrier 22 and is higher than the bearing surface 224. A plurality of support columns 28 may be respectively arranged at positions corresponding to the corner areas of the tray device X, or at other positions, as long as the tray device X does not slide when normally placed on the support columns 28.

[0097] Furthermore, the support column 28 may be arranged at a position such that when the tray device X is placed on the support column 28 , the battery cells in the tray device X are roughly aligned with the suction nozzle 211 in the height direction, thereby facilitating the subsequent exhaust operation.

[0098] Taking the placement of the tray device X as an example, the tray device X can be placed on the support column 28. When exhaust is required, the carrier 22 moves upward and makes the carrier surface 224 abut against the bottom surface of the tray device X, and then the carrier 22 continues to move upward, driving the tray device X to leave the support column 28 and move upward, and finally making the battery cell dock with the suction nozzle 211. When the tray device X needs to be taken out, the carrier 22 can be moved downward to return to the initial position. At this time, the tray device X will be supported by the support column 28, and the tray device X can be directly taken out from the support column 28.

[0099] In some implementations, see Figure 6 The tray device X can enter or leave the placement space 11 along the first direction, at least a portion of the support columns 28 are arranged on opposite sides of the base 25 along the second direction, and the top side surface of the support column 28 has a guide surface 281 and a placement surface 282. The guide surface 281 is inclined toward the tray device X from the top side to the bottom side, and the placement surface 282 is connected to the bottom side of the guide surface 281 and is horizontally arranged. The guide surface 281 is used to guide the tray device X to slide to the placement surface 282. The first direction here intersects with the second direction and is perpendicular to the height direction respectively.

[0100] In this way, when the tray device X enters the placement space 11 along the first direction, the guide surface 281 of the support column 28 can correct the position deviation of the tray device X in the second direction, so that the support column 28 can automatically slide onto the placement surface 282, thereby simplifying the operation. On the other hand, it can also improve the positioning accuracy of the tray device X, which is convenient for subsequent exhaust operations.

[0101] As an example, the number of the support columns 28 can be four, wherein two support columns 28 are arranged on one side of the base 25 along the second direction, and the other two support columns 28 are arranged on the other side of the base 25 along the second direction. The two support columns 28 arranged on the same side of the base 25 along the second direction are arranged at intervals along the first direction. The guide surface 281 of each support column 28 is inclined toward the tray device X from the top end to the bottom end, so as to guide the tray device X to move toward the placement surface 282 below.

[0102] In some implementations, see Figure 5 A positioning pin 225 is provided on the top side surface of the carrier 22, and the positioning pin 225 is used to be inserted into a pin hole (not shown in the figure) on the bottom side of the tray device X along the height direction.

[0103] It can be understood that the advantage of the support column 28 is that it provides a positioning function and facilitates assembly. Compared with the support column 28, the advantage of the positioning pin 225 is that it can more accurately position the tray device X so that the battery cells therein can be more accurately aligned with the suction nozzle 211 in the height direction.

[0104] The number of the positioning pins 225 may be one or more, and there is no limitation on this. In some embodiments, only the support column 28 may be provided for positioning without the positioning pins 225. In some embodiments, only the positioning pins 225 may be provided without the support column 28. In some embodiments, the support column 28 and the positioning pins 225 may be provided at the same time. In this case, the support column 28 is used for the primary positioning of the tray device X, and the positioning pins 225 are used for the secondary positioning of the tray device X. In this way, the positioning accuracy can be taken into account while simplifying the assembly operation.

[0105] In some implementations, see Figure 3 , Figure 7 and Figure 8 The exhaust unit 21 includes: a mounting seat 211, which extends along a first direction; an exhaust pipe 213, which is arranged on the mounting seat; and a plurality of suction nozzles 211 distributed along the first direction, which are arranged on the mounting seat 212 and connected to the exhaust pipe 213, wherein the mounting seat 212 is connected to the top seat 24 and can slide relative to the top seat 24 along the first direction, and the first direction intersects with the height direction.

[0106] In this way, the exhaust unit 21 can simultaneously exhaust multiple battery cells distributed along the first direction, and the exhaust unit 21 and the top seat 24 can be installed and disassembled by sliding the mounting seat 212 along the first direction, which is convenient for maintenance. In addition, the relative position of the suction nozzle 211 and the battery cell along the first direction can be adjusted by sliding the mounting seat 212 along the first direction, which is convenient for adapting to different models of battery trays, battery cells, etc.

[0107] As an example, a slider 2121 may be provided on the top of the mounting seat 212, and the top seat 24 may have a groove (not shown) extending along the first direction, and the slider 2121 and the groove may slide and fit along the first direction, thereby achieving the connection between the mounting seat 212 and the top seat 24, and the sliding fit along the first direction. Further, the cross section of the slider 2121 perpendicular to the first direction may be T-shaped, thereby limiting the mounting seat 212 in the height direction.

[0108] Of course, the mounting seat 212 may have a groove, and the top seat 24 may have a slider 2121, or other structures capable of sliding fit (such as pulleys and slide rails) may be used to achieve the above effect, which is not limited.

[0109] In some implementations, see Figure 7 and Figure 8 , the mounting seat 212 is provided with a plurality of mounting positions 212a arranged along the first direction. The suction nozzle 211 can be mounted on any mounting position 212a. The mounting position 212a here can be understood as a fixed position of the suction nozzle 211 on the mounting seat 212. The first direction here intersects with the height direction.

[0110] The suction nozzle 211 can be arranged at any position of the mounting seat 212 along the first direction. For example, a strip hole extending along the first direction is formed on the mounting seat 212, and a fastener can pass through any position of the strip hole to fasten the suction nozzle 211 to the mounting seat 212. In this embodiment, the mounting position 212a can be understood as the position where the fastener is fastened on the strip hole. With this type of mounting position 212a, the suction nozzle 211 can be installed at any position on the mounting seat 212 within the movement range of the suction nozzle 211 along the first direction, that is, the suction nozzle 211 can be installed at any position on the mounting seat 212, that is, the mounting position 212a of the suction nozzle 211 on the mounting seat 212 can be adjusted steplessly.

[0111] Of course, the mounting positions 212a may also be specific structures arranged at intervals along the first direction, so that the suction nozzle 211 can be installed on any mounting position 212a.

[0112] By providing a plurality of mounting positions 212 a arranged along the first direction, it is convenient to install the suction nozzle 211 on the mounting seat 212 , and at the same time, it is convenient to realize that the mounting position 212 a of the suction nozzle 211 on the mounting seat 212 is adjustable.

[0113] In some implementations, see Figure 7 and Figure 8The exhaust unit 21 further includes a first stopper 214 and a second stopper 215 which are spaced apart on the suction nozzle 211 along the height direction. At least a portion of the mounting seat 212 is sandwiched between the first stopper 214 and the second stopper 215. A clamping portion 2141 is provided on the first stopper 214. The first stopper 214 can move along the height direction so that the clamping portion 2141 can be clamped on the mounting position 212a or separated from the mounting position 212a.

[0114] The shapes of the first limiting member 214 and the second limiting member 215 are not limited, and can be block-shaped, for example.

[0115] The first limiting member 214 can move along the height direction so that the clamping portion 2141 can be clamped on the mounting position 212a or separated from the mounting position 212a. This means that, on the same mounting position 212a, by moving the first limiting member 214 on one side along the height direction, the clamping portion 2141 can be clamped on the mounting position 212a, and by moving the first limiting member 214 on the other side along the second direction, the clamping portion 2141 can be detached from the mounting position 212a.

[0116] It can be understood that at least a portion of the mounting seat 212 is clamped between the first limit piece 214 and the second limit piece 215. Then, the first limit piece 214 moves on one side in the height direction, so that the first limit piece 214 and the second limit piece 215 can abut against the mounting seat 212, thereby achieving stable installation of the suction nozzle 211 on the mounting seat 212 along the height direction. The first limit piece 214 moves on the other side in the height direction, so that at least one of the first limit piece 214 and the second limit piece 215 can be separated from the mounting seat 212. At the same time, according to the above, the clamping portion 2141 is also detached from the current mounting position 212a. In this way, the suction nozzle 211 can move along the first direction to another mounting seat 212.

[0117] That is to say, by only controlling the first limit member 214 to generate movement in the height direction, the suction nozzle 211 can be connected or separated from one mounting position 212a, and the suction nozzle 211 can also be moved along the first direction to another mounting position 212a, thereby improving the convenience of installing the suction nozzle 211 and adjusting the mounting position 212a.

[0118] For some implementations, please refer to Figure 7 and Figure 8 One of the mounting position 212a and the clamping portion 2141 is a groove, and the other is a protrusion. The protrusion extends along the height direction.

[0119] Specifically, the installation position 212a may be a groove, and the clamping portion 2141 may be a protrusion.

[0120] The first limiting member 214 moves along the height direction, and the protrusion can extend into the groove or escape from the groove. When the protrusion extends into the groove, the first limiting member 214 is limitedly matched with the frame along the first direction.

[0121] The size of the protrusion can be matched with the size of the groove, that is, the size of the groove is slightly larger than the size of the protrusion, thereby reducing the difficulty of the protrusion extending into the groove.

[0122] The clamping mode of the protrusion and the groove is relatively simple, which is conducive to the clamping portion 2141 to be clamped or separated from the installation position 212a.

[0123] In some implementations, please refer to Figure 7 and Figure 8 A slide groove 2122 extending along the first direction is provided on the mounting seat 212. The suction nozzle 211 is movably disposed in the slide groove 2122 along the first direction.

[0124] It can be understood that the first limiting member 214 and the second limiting member 215 are located at two opposite sides of the sliding groove 2122 along the height direction.

[0125] Furthermore, when a groove is further provided on the mounting seat 212 , the groove is located on a side of the slide slot 2122 close to the first limiting member 214 along the height direction.

[0126] When the suction nozzle 211 moves along the first direction to switch between the multiple installation positions 212a, the slide groove 2122 can provide a guide for the movement of the suction nozzle 211, so as to facilitate the suction nozzle 211 to move to the installation position 212a to be installed.

[0127] In some embodiments, the exhaust unit 21 further includes a first elastic reset member 216. Under the action of an external force, the first limit member 214 can move in the height direction so that the clamping portion 2141 is separated from the mounting position 212a, and the first elastic reset member 216 is elastically deformed. After the external force is removed, the first elastic reset member 216 restores the elastic deformation so that the clamping portion 2141 is clamped with the mounting position 212a.

[0128] The type of the first elastic reset member 216 is not limited. For example, it can be a tension spring, a compression spring, etc. Specifically, the first elastic reset member 216 can be a compression spring extending in the height direction. The first elastic reset member 216 is arranged on a side of the first limit member 214 away from the second limit member 215 in the height direction. When the first limit member 214 moves in the height direction toward the side away from the second limit member 215, the compression spring is compressed.

[0129] Specifically, when the clamping portion 2141 is a protrusion and the mounting position 212a is a groove, the first elastic return member 216 can enable the protrusion to be stably set in the groove. Under the action of external force, the first limiting member 214 moves along the height direction. After the protrusion is disengaged from the groove, the suction nozzle 211 is controlled to move along the first direction so that the protrusion can match another groove. At this time, the external force is removed, and the first elastic return member 216 restores its elastic deformation to push the protrusion into the groove.

[0130] Through the first elastic reset member 21635, on the one hand, the reliability of the clamping connection between the clamping portion 214133a and the mounting position 212a can be made higher. On the other hand, after the first elastic reset member 21635 produces elastic deformation, it can provide a certain elastic force. Under the action of this elastic force, the clamping portion 214133a can be easily clamped with the mounting position 212a, which is convenient for the operator to operate.

[0131] In some implementations, see Figure 7 and Figure 8 The exhaust unit 21 further includes a second elastic reset member 217. Under the action of external force, the second limit member 215 can move in the height direction and separate from the mounting seat 212, and the second elastic reset member 217 generates elastic deformation. After the external force is lost, the second elastic reset member 217 restores the elastic deformation so that the second limit member 215 abuts against the mounting seat 212.

[0132] The type of the second elastic reset member 217 is not limited. For example, it can be a compression spring, a tension spring, etc. Specifically, the second elastic reset member 217 can be a compression spring extending in the height direction, and the second elastic reset member 217 is arranged on the side of the second limit member 215 away from the first limit member 214 in the height direction. When the second limit member 215 moves toward the side away from the first limit member 214 in the height direction, the compression spring is compressed.

[0133] The second limiting member 215 is abutted against the mounting seat 212 via the second elastic return member 217. On the one hand, the second elastic return member 217 can produce elastic deformation, thereby facilitating the second limiting member 215 to release the limiting relationship with the mounting seat 212 along the height direction, and then facilitating the movement of the suction nozzle 211 to any mounting position 212a; on the other hand, the second elastic return member 217 can abut the second limiting member 215 against the mounting seat 212 in the reset state, thereby improving the installation stability of the suction nozzle 211 on the mounting seat 212.

[0134] In some implementations, see Figure 3 and Figure 4The exhaust mechanism 2 includes a moving frame 241 and a second driving member 29. The moving frame 241 is installed on the top seat 24. The mounting seat 212 is connected to the moving frame 241. The second driving member 29 is used to drive the moving frame 241 to move along the second direction to drive the mounting seat 212 to move along the second direction. The first direction intersects with the second direction and is perpendicular to the height direction respectively.

[0135] In this way, the position of the exhaust unit 21 can be adjusted in the second direction to accommodate battery cells of different models.

[0136] The specific structure of the second driving member 29 is not limited, for example, it can be a cylinder, an electric cylinder, an oil cylinder, etc. The specific structure of the moving frame 241 is not limited, and it can be connected to the top seat 24 and slide with the top seat 24 along the second direction.

[0137] In some implementations, see Figure 4 The exhaust mechanism 2 may include a position indicator 242, which is mounted to the top seat 24 and is used to indicate the relative position of the mounting seat 212 and the top seat 24 in the second direction. In this way, it is convenient to position the mounting seat 212 in the second direction in actual operation.

[0138] As an example, the position indicator 242 may include a pointer and a ruler, one of which is mounted to the top seat 24, and the other is mounted to the movable frame 241, and the pointer and the ruler are slidably matched along the second direction, such as by means of a rack or other device to achieve sliding fit, so that the position of the mounting seat 212 can be determined according to the position indicated by the pointer on the ruler.

[0139] In some embodiments, see Figure 1 and Figure 3 The shelf device may further include a fire-fighting mechanism 3, the specific structure of which is not limited. As an example, the fire-fighting mechanism 3 may include a smoke sensor 31 and a fire-fighting pipe. The smoke sensor 31 may be disposed on a side surface of the top seat 24 of the exhaust mechanism 2, such as on the top side surface of the top seat 24. The fire-fighting pipe 32 may be disposed on the top seat 24 and extend along the circumference of the top seat 24. When a fire occurs, it may spray liquid or fire-fighting gas to a location such as the pallet device X.

[0140] The shelf device involved in one or more of the above embodiments will be described in more detail below in conjunction with a specific embodiment.

[0141] See also Figure 1-Figure 8 The shelf device provided in the embodiment of the present application includes a shelf 1 and an exhaust mechanism 2.

[0142] The shelf 1 has a plurality of placement spaces 11. Figure 1 and Figure 2In the illustrated embodiment, the shelf 1 has three placement spaces 11 distributed along the height direction, and an exhaust mechanism 2 is provided in each placement space 11. One side of the placement space 11 along a first direction is open, so that the tray device X can enter or leave the placement space 11 along the first direction, which is perpendicular to the height direction.

[0143] The exhaust mechanism 2 includes a plurality of exhaust units 21, which are arranged along a second direction, wherein the second direction is perpendicular to the first direction and the height direction. Each exhaust unit 21 has a plurality of suction nozzles 211 distributed along the first direction.

[0144] The exhaust mechanism 2 also includes a carrier 22 and a first driving member 23. The carrier 22 is used to carry the tray device X. The carrier 22 is arranged on the bottom side of the exhaust unit 21. The first driving member 23 can drive the carrier 22 to move in the height direction, thereby driving the tray device X to move, so that the battery cells carried by the tray device X can be docked or separated from the suction nozzle 211.

[0145] The exhaust mechanism 2 further includes a top seat 24, a base 25 and a plurality of connecting rods 26, the top seat 24 is located on the top side of the base 25, and the two are connected by the connecting rods 26, the bearing 22 is located between the top seat 24 and the base 25, and the exhaust unit 21 is arranged on the top seat 24. The bearing 22 has a linear bearing, the connecting rod 26 is inserted into the linear bearing, and the two are slidably matched in the height direction, so that the connecting rod 26 can also guide the bearing 22 when it moves in the height direction.

[0146] The first driving member 23 specifically includes a cylinder, which includes a cylinder barrel 231 and a cylinder rod 232 . The top end of the cylinder barrel 231 is connected to the base 25 , and the bottom end of the cylinder rod 232 is connected to the floating joint 221 on the bearing member 22 .

[0147] A plurality of limit rods 27 are provided on the top surface of the carrier 22. Specifically, two limit rods 27 are provided on opposite sides of the carrier 22 along the second direction, and the two limit rods 27 on the same side are spaced apart along the first direction. When the battery cell is docked with the suction nozzle 211, the limit rods 27 can abut against the top seat 24, thereby preventing the carrier 22 from continuing to move toward the suction nozzle 211, thereby preventing the battery cell and the suction nozzle 211 from being squeezed against each other and causing damage.

[0148] The exhaust mechanism 2 further includes a plurality of support columns 28, which are disposed on the base 25. Specifically, two support columns 28 are disposed on opposite sides of the base 25 along the second direction, and the two support columns 28 on the same side are disposed at intervals along the first direction. The top side surface of the support column 28 has a guide surface 281 and a placement surface 282, wherein the guide surface 281 is tilted toward the tray device X from the top side to the bottom side, and the placement surface 282 is connected to the bottom side of the guide surface 281 and is disposed horizontally, so that when the tray device X is placed along the first direction, the tray device X will slide to the placement surface 282 under the guidance of the guide surface 281.

[0149] The carrier 22 has a hollow portion 223 and a bearing surface 224 for bearing the tray device X. When the carrier 22 is in the initial position, the top of the support column 28 passes through the hollow portion 223 and is higher than the bearing surface 224, so that each support column 28 is used to support the tray device X when the carrier 22 is in the initial position.

[0150] The initial position here refers to the lowest position of the carrier 22 in the height direction. Taking the placement of the tray device X as an example, the tray device X can be placed on the support column 28. When exhaust is required, the carrier 22 moves upward and makes the bearing surface 224 abut against the bottom surface of the tray device X, and then the carrier 22 continues to move upward, driving the tray device X to leave the support column 28 and move upward, and finally making the battery cell dock with the suction nozzle 211. Taking the removal of the tray device X as an example, the carrier 22 can be moved downward back to the initial position, at which time the tray device X will be supported by the support column 28, and the tray device X can be directly removed from the support column 28.

[0151] Furthermore, a positioning pin 225 is provided on the top surface of the carrier 22, and the positioning pin 225 is used to be inserted into a pin hole (not shown) on the bottom side of the tray device X in the height direction. The positioning pin 225 can perform secondary positioning on the support device to improve the positioning accuracy. Two positioning pins 225 are provided, and the two positioning pins 225 are respectively located on opposite sides of the carrier 22 along the first direction, and respectively located on opposite sides of the carrier 22 along the second direction. In other words, the two positioning pins 225 are respectively located at two opposite corner areas of the carrier 22.

[0152] The exhaust unit 21 includes a specific mounting seat 212, an exhaust pipeline 213, and a plurality of suction nozzles 211 distributed along the first direction, wherein the suction nozzles 211 are arranged on the mounting seat 212 and are connected to the exhaust pipeline 213. The exhaust mechanism 2 also includes a mobile frame 241 and a second driving member 29, wherein the mobile frame 241 is mounted to the top seat 24, and the mounting seat 212 is mounted to the mobile frame 241, wherein the second driving member 29 can drive the mobile frame 241 to move along the second direction, thereby driving the exhaust unit 21 to move along the second direction, wherein a pointer is arranged on the mounting seat 212, and a scale is arranged on the top seat 24, and the position of the exhaust unit 21 in the second direction can be determined by the relative position of the pointer and the scale. The mounting seat 212 and the mobile frame 241 are slidably matched in the first direction, thereby enabling the exhaust unit 21 to be pulled out or inserted into the mobile frame 241 in the first direction.

[0153] An embodiment of the present application further provides a battery production line, which includes: a tray device X for loading battery monomers; a static station, which is provided with a shelf device as described in any of the above embodiments, for placing the tray device X; a transfer device, which is used to transfer the tray device X on the static station to a formation station; and the formation station is used to perform formation processing on the battery monomers on the tray device X transferred by the transfer device.

[0154] In this embodiment, a shelf device is arranged in the static station of the battery production line, and the shelf device can exhaust the battery monomers carried by the tray device X placed therein, so that the battery monomers can be exhausted before being transferred to the formation station, thereby improving the quality of the battery monomers.

[0155] It should be noted that the transfer device may also transfer the tray device X on the static station to one or more other stations before moving the tray device X on the static station to the formation station, and there is no limitation to this.

[0156] The specific structures of the tray device X, the transfer device and the formation station can refer to the relevant technology in the field and are not limited to this.

[0157] In some embodiments, the transfer device can also be used to transfer the tray device X on the formation station to the static station described above, or to another static station equipped with the above-mentioned shelf device, so that the battery cells can continue to be exhausted after the formation process, further improving the battery quality.
