Since both the first rotating shaft and the second rotating shaft cooperate with the conveying mechanism, when the first rotating shaft and the second rotating shaft rotate, the conveying mechanism can be driven to operate.

[0056] Currently, from the perspective of the development of the market situation, 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 transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0057] In the production process of power batteries, it is necessary to convey the battery cells through a conveyor line to facilitate the transfer of the battery cells.

[0058] In the conveying line in the related art, during the conveying process, most of them drive a single shaft to rotate through a motor. At this time, the two sprockets connected to the single shaft rotate synchronously. Subsequently, the two sprockets drive the rollers to rotate through the corresponding chains, and the rollers drive the belt to rotate, so as to realize the conveying of the battery cells on the belt. Since the single shaft itself is relatively long, when the two sprockets connected to the single shaft rotate, there is mostly uneven force at both ends of the single shaft. After the single shaft runs for a long time, there is a risk of breakage of the single shaft.

[0059] Based on the above considerations, in order to solve the problem that the existing single shaft breaks due to uneven force during rotation, a conveying line is designed, which includes a frame and a conveying mechanism arranged on the frame. The conveying line further includes: a driving mechanism, which includes a driving member, a first rotating shaft, a second rotating shaft and a connecting member; the driving member, the first rotating shaft and the second rotating shaft are all arranged on the frame, and both the first rotating shaft and the second rotating shaft can rotate around the axis; the output end of the driving member is connected to the first rotating shaft, and one end of the first rotating shaft away from the driving member is connected to the second rotating shaft through the connecting member; and both the first rotating shaft and the second rotating shaft cooperate with the conveying mechanism; the connecting member is used to adjust the direction of the transmission axis between the first rotating shaft and the second rotating shaft, so that the second rotating shaft can rotate relative to the first rotating shaft in multiple degrees of freedom.

[0060] Since both the first rotating shaft and the second rotating shaft cooperate with the conveying mechanism, when the first rotating shaft and the second rotating shaft rotate, they can drive the conveying mechanism to operate. When the first rotating shaft and the second rotating shaft are unevenly stressed during rotation, the second rotating shaft can rotate relative to the first rotating shaft in multiple degrees of freedom. At this time, under the action of the connecting member, the first rotating shaft and the second rotating shaft can still rotate normally, so that the first rotating shaft and the second rotating shaft will not break due to uneven force, and the problem that the single shaft breaks due to uneven force during rotation is solved.

[0061] The conveying line disclosed in the embodiment of the present application can be but is not limited to being used in the production of battery electrodes. It should be noted that the battery in the present application refers to a single physical module including one or more battery monomers to provide higher voltage and capacity. For example, the battery mentioned in the present application can include a battery pack, etc. The battery can be used as the power source or power system of the electrical device. In this way, it is beneficial to improve the overall performance of the battery and facilitate the popularization of the battery.

[0062] The above-mentioned electrical device can be but is not limited to mobile phones, tablets, laptop computers, electric toys, electric tools, battery cars, electric vehicles, ships, spacecrafts, etc. Among them, the electric toys can include fixed or mobile electric toys. For example, game consoles, electric vehicle toys, electric ship toys and electric aircraft toys, etc. The spacecraft can include airplanes, rockets, space shuttles and spaceships, etc.

[0063] For the convenience of description, in the following embodiments, a power consumption device according to an embodiment of the present application is taken as an example of a vehicle 1000 for illustration.

[0064] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of the vehicle 1000 provided in some embodiments of the present application. The vehicle 1000 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, an extended-range vehicle, etc. A battery 100 is disposed inside the vehicle 1000. The battery 100 can be disposed at the bottom, head, or tail of the vehicle 1000. The battery 100 can be used for power supply of the vehicle 1000. For example, the battery 100 can be used as an operating power source of the vehicle 1000. The vehicle 1000 can further include a controller 200 and a motor 300. The controller 200 is used to control the battery 100 to supply power to the motor 300. For example, it is used for the power consumption requirements during the start, navigation, and driving of the vehicle 1000.

[0065] In some embodiments of the present application, the battery 100 can not only be used as an operating power source of the vehicle 1000, but also as a driving power source of the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0066] Please refer to Figure 2 , Figure 2 , which is an exploded view of the battery 100 provided in some embodiments of the present application. The battery 100 includes a box body 110 and battery cells 120. The battery cells 120 are accommodated in the box body 110. Among them, the box body 110 is used to provide an accommodation space for the battery cells 120, and the box body 110 can adopt various structures. In some embodiments, the box body 110 can include a first part 111 and a second part 112. The first part 111 and the second part 112 are covered with each other, and the first part 111 and the second part 112 jointly define an accommodation space for accommodating the battery cells 120. The second part 112 can be a hollow structure with one end open, and the first part 111 can be a plate-like structure. The first part 111 covers the open side of the second part 112, so that the first part 111 and the second part 112 jointly define the accommodation space; the first part 111 and the second part 112 can also be hollow structures with one side open, and the open side of the first part 111 covers the open side of the second part 112. Of course, the box body 110 formed by the first part 111 and the second part 112 can be in various shapes, such as a cylinder, a cuboid, etc.

[0067] In battery 100, there may be multiple battery cells 120. The multiple battery cells 120 can be connected in series, parallel or in a combined series-parallel connection. A combined series-parallel connection means that there are both series and parallel connections among the multiple battery cells 120. The multiple battery cells 120 can be directly connected in series, parallel or in a combined series-parallel connection together, and then the whole formed by the multiple battery cells 120 is accommodated in the box 110. Of course, battery 100 can also be in the form that multiple battery cells 120 are first connected in series, parallel or in a combined series-parallel connection to form battery modules, and then multiple battery modules are connected in series, parallel or in a combined series-parallel connection to form a whole and are accommodated in the box 110. Battery 100 can also include other structures. For example, battery 100 can also include a busbar component for realizing the electrical connection among the multiple battery cells 120.

[0068] Among them, each battery cell 120 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery or a magnesium-ion battery, but not limited thereto. The battery cell 120 can be in the shape of a cylinder, a flat body, a cuboid or other shapes, etc.

[0069] As Figure 3 shown, the battery cell 120 can include a housing, an electrode assembly 123 and electrode terminals. The housing includes a shell 121 and an end cap 122. The shell 121 has an opening, and the end cap 122 closes the opening to isolate the internal environment of the battery cell 120 from the external environment.

[0070] The shell 121 is a component for cooperating with the end cap 122 to form the internal environment of the battery cell 120. Among them, the formed internal environment can be used to accommodate the electrode assembly 123, the electrolyte and other components. The shell 121 and the end cap 122 can be independent components. The shell 121 can be in various shapes and various sizes. Specifically, the shape of the shell 121 can be determined according to the specific shape and size of the electrode assembly 123. The material of the shell 121 can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc.

[0071] The end cap 122 refers to a component that covers the opening of the housing 121 to isolate the internal environment of the battery cell 120 from the external environment. Without limitation, the shape of the end cap 122 can be adapted to the shape of the housing 121 to fit the housing 121. Optionally, the end cap 122 can be made of a material with a certain hardness and strength (such as aluminum alloy). In this way, the end cap 122 is not easily deformed when subjected to extrusion and collision, enabling the battery cell 120 to have higher structural strength and improved reliability. Functional components such as electrode terminals can be provided on the end cap 122. The electrode terminals can be used to electrically connect to the electrode assembly 123 for outputting or inputting the electrical energy of the battery cell 120. The material of the end cap 122 can also be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not impose special restrictions on this. In some embodiments, an insulating structure can also be provided on the inner side of the end cap 122, and the insulating structure can be used to isolate the electrical connection components in the housing 121 from the end cap 122 to reduce the risk of short circuit. Exemplarily, the insulating structure can be plastic, rubber, etc.

[0072] The electrode assembly 123 is a component in the battery cell 120 where an electrochemical reaction occurs. The housing 121 can contain one or more electrode assemblies 123. The electrode assembly 123 is mainly formed by winding or laminating a positive electrode plate and a negative electrode plate, and usually an isolation film is provided between the positive electrode plate and the negative electrode plate. The isolation film is used to separate the positive electrode plate and the negative electrode plate to prevent internal short circuit between the positive electrode plate and the negative electrode plate. The parts of the positive electrode plate and the negative electrode plate with active substances constitute the main body of the electrode assembly 123, and the parts of the positive electrode plate and the negative electrode plate without active substances respectively constitute the electrode tabs. The positive electrode tab and the negative electrode tab can be located at one end of the main body together or at both ends of the main body respectively. During the charging and discharging process of the battery 100, the positive active substance and the negative active substance react with the electrolyte, and the electrode tabs are connected to the electrode terminals to form a current loop. In addition, the electrode assembly 123 can be a wound structure or a stacked structure.

[0073] In some embodiments, the battery cell 120 can also be provided with a pressure relief mechanism for releasing the internal pressure when the internal pressure or temperature of the battery cell 120 reaches a threshold value.

[0074] According to some embodiments of the present application, refer to Figure 4 , and please further refer to Figure 5 and Figure 6 , where Figure 5 is a schematic structural diagram of another conveyor line in the present application, Figure 6It is a schematic structural diagram of another conveyor line in this application. This application provides a conveyor line, including a frame, a conveying mechanism and a driving mechanism arranged on the frame. The driving mechanism includes a driving member 10, a first rotating shaft 11, a second rotating shaft 12 and a connecting member 13. Among them, the driving member 10, the first rotating shaft 11 and the second rotating shaft 12 are all arranged on the frame, and both the first rotating shaft 11 and the second rotating shaft 12 can rotate around the axial direction. The output end of the driving member 10 is connected to the first rotating shaft 11, and the end of the first rotating shaft 11 away from the driving member 10 is connected to the second rotating shaft 12 through the connecting member 13. And both the first rotating shaft 11 and the second rotating shaft 12 cooperate with the conveying mechanism. The connecting member 13 is used to adjust the direction of the transmission axis between the first rotating shaft 11 and the second rotating shaft 12, so that the second rotating shaft 12 can rotate relative to the first rotating shaft 11 in multiple degrees of freedom.

[0075] In this embodiment, the driving member 10 can be a stepping motor, a servo motor, etc., and specifically can be determined according to the actual situation, and this embodiment of the specification does not limit this.

[0076] At the same time, the output shaft of the driving member 10 and the first rotating shaft 11 can be connected through a bearing seat, a coupling, etc., and specifically can be determined according to the actual situation, and this embodiment of the specification does not limit this.

[0077] The connecting member 13 in this embodiment can be a universal joint, etc., and specifically can be determined according to the actual situation, and this embodiment of the specification does not limit this. For the convenience of description below, the connecting member 13 is taken as a universal joint as an example for description.

[0078] Since the universal joint itself can change the position of the transmission axis direction and allows the included angle between the connected parts to change within a certain range, in this way, the forces on the first rotating shaft 11 and the second rotating shaft 12 in the axial and radial directions can be weakened, so that the first rotating shaft 11 and the second rotating shaft 12 can be prevented from breaking due to uneven stress.

[0079] The conveying mechanism in this embodiment can be a belt conveyor, a chain conveyor, etc., and specifically can be determined according to the actual situation, and this embodiment of the specification does not limit this.

[0080] In this embodiment, the driving member 10 is fixed to the frame by bolts, and the first rotating shaft 11 and the second rotating shaft 12 can be fixed to the frame through bearing seats. At the same time, the first rotating shaft 11 is connected to the first chain on the conveying mechanism, and the second rotating shaft 12 is connected to the second chain on the transmission mechanism. By driving the driving member 10 to drive the first rotating shaft 11 and the second rotating shaft 12 to rotate, the first rotating shaft 11 and the second rotating shaft 12 drive the corresponding first chain and second chain to rotate, so that the transmission mechanism can be driven to operate.

[0081] In the technical solution of the embodiment of the present application, the driving member 10 drives the first rotating shaft 11 to rotate, and the first rotating shaft 11 can drive the second rotating shaft 12 to rotate through the connecting member 13. Since both the first rotating shaft 11 and the second rotating shaft 12 cooperate with the conveying mechanism, when the first rotating shaft 11 and the second rotating shaft 12 rotate, the conveying mechanism can be driven to operate. When the first rotating shaft 11 and the second rotating shaft 12 are unevenly stressed during rotation, since the second rotating shaft 12 can rotate relative to the first rotating shaft 11 in multiple degrees of freedom, at this time, under the action of the connecting member 13, the first rotating shaft 11 and the second rotating shaft 12 can still rotate normally, and the first rotating shaft 11 and the second rotating shaft 12 will not break due to uneven stress, thereby improving the reliability of the overall conveyor line.

[0082] Moreover, the rotating shafts in the present application are of an overall segmented structure. Compared with the existing single shaft, the lengths of the first rotating shaft 11 and the second rotating shaft 12 in the present application are both smaller than the length of the existing single shaft. In this way, due to the short self-lengths of the first rotating shaft 11 and the second rotating shaft 12, during operation, the swing amplitudes of the first rotating shaft 11 and the second rotating shaft 12 are small, thereby improving the running smoothness of the overall conveyor line.

[0083] According to some embodiments of the present application, as Figure 4 shown, the conveyor line further includes a support member 15 and a first box body 16. Among them, the first box body 16 is arranged on the frame, the support member 15 is arranged between the driving member 10 and the first box body 16, and one end of the first rotating shaft 11 far from the driving member 10 passes through the first box body 16 and is connected to the connecting member 13.

[0084] The first box body 16 in this embodiment can be fixed to the frame by bolts, or can be clamped on the frame, which can be specifically determined according to the actual situation, and the embodiments of this specification do not limit this.

[0085] In this embodiment, one end of the support member 15 is connected to the driving member 10 by bolts, and the other end of the support member 15 is connected to the first box body 16 by bolts, which can be specifically determined according to the actual situation, and the embodiments of this specification do not limit this.

[0086] During use, when the driving member 10 generates vibration during operation, through the buffering of the support member 15, the synchronous vibration of the first box body 16 can be reduced, and further the vibration of the first rotating shaft 11 in the first box body 16 can be reduced, ensuring the smoothness of the first rotating shaft 11 during operation.

[0087] According to some embodiments of the present application, as Figure 4 shown, the interior of the support member 15 is provided with an inner cavity 151, and the inner cavity 151 communicates with the outside.

[0088] The support member 15 in this embodiment may be a cubic structure. The inner cavity of the cube is a hollow structure, and each face of the cube is an open structure. The inner cavity communicates with the outside through the openings on each face. Of course, it can be understood that the support member 15 may also be other structures. For example, the support member 15 includes multiple support columns, which can be specifically determined according to the actual situation, and the embodiments of this specification do not limit this.

[0089] Since the inner cavity 151 communicates with the outside, when the driving member 10 generates vibrations during movement, part of the vibrations will be transmitted to the external space through the inner cavity 151, further reducing the vibrations.

[0090] According to some embodiments of the present application, as Figure 4 shown, the conveyor line further includes a coupling 14. The coupling 14 is located in the inner cavity 151, and the output end of the driving member 10 is connected to the first rotating shaft 11 through the coupling 14.

[0091] Since the coupling 14 itself can compensate for the axis offset, it has high elasticity not only in torsion but also in the axial, radial, and angular directions. In this way, when the first rotating shaft 11 rotates, the force imbalance between the first rotating shaft 11 and the output end of the driving member 10 can be reduced, and the phenomenon that the first rotating shaft 11 tilts or breaks relative to the output end of the driving member 10 can be avoided.

[0092] According to some embodiments of the present application, as Figure 7 and combined with Figure 8 shown, the conveyor line further includes a first sprocket 25. The first sprocket 25 is arranged on the first rotating shaft 11, and the first sprocket 25 is located in the first box body 16. At the same time, a first opening 161 is provided on one side of the first box body 16 along the radial direction of the first rotating shaft 11, and the chain on the conveying mechanism passes through the first opening 161 and is connected to the first sprocket 25.

[0093] The first sprocket 25 and the first rotating shaft 11 in this embodiment may be connected by a key, or there may be an interference fit between the first sprocket 25 and the first rotating shaft 11, which can be specifically determined according to the actual situation, and the embodiments of this specification do not limit this.

[0094] In this embodiment, the first sprocket 25 is a double-speed sprocket. Of course, it can be understood that the first sprocket 25 may also be an ordinary sprocket, which can be specifically determined according to the actual situation, and the embodiments of this specification do not limit this.

[0095] During use, when the first rotating shaft 11 rotates, the first rotating shaft 11 can drive the first sprocket 25 to rotate synchronously. At this time, the first sprocket 25 can drive the chain on the transmission mechanism to rotate.

[0096] According to some embodiments of the present application, as Figure 8As shown, the conveyor line further includes a first belt 21 and a first pulley 22. The first belt 21 and the first pulley 22 are both disposed within the first housing 16, and the first pulley 22 is capable of rotating relative to the first housing 16. Meanwhile, the first belt 21 is sleeved between the first rotating shaft 11 and the first pulley 22.

[0097] In this embodiment, both ends of the first pulley 22 are rotatably connected to opposite inner sides of the first housing 16 through rotating shafts, and the axial direction of the first pulley 22 is parallel to the axial direction of the first rotating shaft 11.

[0098] When the first rotating shaft 11 rotates, it can drive the first pulley 22 to rotate through the first belt 21. At this time, the first pulley 22 can be used to drive other components to rotate or move.

[0099] According to some embodiments of the present application, as Figure 6 shown, the conveyor line further includes a second housing 17. The second housing 17 is disposed on the frame, and one end of the second rotating shaft 12 away from the connecting member 13 passes through the second housing 17 and extends to the outside.

[0100] In this embodiment, the second housing 17 can be fixed to the frame by bolts, or the second housing 17 can be snap - connected to the frame. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0101] After the second housing 17 is fixed to the frame, one end of the second rotating shaft 12 away from the connecting member 13 can pass through the second housing 17 and extend to the outside. At this time, through the second housing 17, the position of one end of the second rotating shaft 12 away from the connecting member 13 can be fixed.

[0102] According to some embodiments of the present application, as Figure 4 and combined with Figure 7 shown, the conveyor line further includes a second sprocket 26. The second sprocket 26 is disposed on the second rotating shaft 12, and the second sprocket 26 is located within the second housing 17. A second opening 171 is provided on one side of the second housing 17 along the radial direction of the second rotating shaft 12, and the chain on the conveying mechanism passes through the second opening 171 and is connected to the second sprocket 26.

[0103] In this embodiment, the second sprocket 26 and the second rotating shaft 12 can be connected by a key, or there is an interference fit between the second sprocket 26 and the second rotating shaft 12. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0104] In this embodiment, the second sprocket 26 is a double - speed sprocket. Of course, it can be understood that the second sprocket 26 can also be an ordinary sprocket. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0105] During use, when the second rotating shaft 12 is rotating, the second rotating shaft 12 can drive the second sprocket wheel 26 to rotate synchronously. At this time, the second sprocket wheel 26 can drive the chain on the transmission mechanism to rotate.

[0106] According to some embodiments of the present application, Figure 4 As shown, the conveyor line also includes a fixed plate 18 and a bearing 20, wherein the fixed plate 18 is arranged on the side of the second box body 17 facing the driving member 10, and the bearing 20 is arranged on the fixed plate 18; the end of the second rotating shaft 12 away from the connecting member 13 passes through the bearing 20 and the second box body 17 in sequence and then extends to the outside.

[0107] The fixing plate 18 in this embodiment can be fixed to the side of the second box 17 facing the driving member 10 by a fastener 19. The fastener 19 can be a bolt, a buckle, etc., which can be determined according to actual conditions and is not limited in this embodiment of the specification.

[0108] The bearing 20 in this embodiment may be a deep groove ball bearing. Of course, it is understandable that the bearing 20 may also be an angular contact bearing. The specific bearing may be determined according to actual conditions, and this specification does not limit this.

[0109] Since the deep groove ball bearing itself can disperse the axial force on the second rotating shaft 12 and provide a smooth transmission, the second rotating shaft 12 can be ensured to run smoothly. Of course, it is understandable that

[0110] When in use, since the end of the second rotating shaft 12 away from the connecting member 13 is located in the bearing 20, it is possible to avoid friction between the second rotating shaft 12 and the second housing 17 when the second rotating shaft 12 rotates.

[0111] According to some embodiments of the present application, Figure 9 As shown, a bearing hole 181 is provided on the side of the fixing plate 18 facing the driving member 10, and a limiting hole 182 is provided on the side of the fixing plate 18 facing away from the driving member 10, and the diameter of the bearing hole 181 is larger than the diameter of the limiting hole 182; at the same time, the bearing 20 and the bearing hole 181 are clearance-fitted, and the diameter of the bearing 20 is larger than the diameter of the limiting hole 182; the end of the second rotating shaft 12 away from the connecting member 13 passes through the bearing 20, the limiting hole 182, and the second box body 17 in sequence and then extends to the outside.

[0112] refer to Figure 9As shown, since the diameter of the bearing hole 181 is greater than that of the limiting hole 182, at this time, the bearing hole 18 and the limiting hole 182 as a whole present a stepped structure. When the bearing 20 is located within the bearing hole 181, at this time, the bearing 20 has a clearance fit with the bearing hole 181. Since the diameter of the bearing 20 is greater than that of the limiting hole 182, at this time, under the limitation of the right side surface of the limiting hole 182, the bearing 20 cannot move axially to the left, thereby avoiding the bearing 20 running towards the second sprocket 26 side.

[0113] According to some embodiments of the present application, as Figure 9 and in combination with Figure 10 shown, the conveyor line further includes a retaining ring 183, and the inner diameter of the retaining ring 183 is smaller than the outer diameter of the bearing 20; under the condition that the bearing 20 is disposed in the bearing hole 181, the retaining ring 183 is disposed on the side of the fixing plate 18 facing the driving member 10, and the retaining ring 183 is located around the bearing hole 181.

[0114] The retaining ring 183 in this embodiment may be in an annular structure, or an elastic retaining ring with a notch, and specifically can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0115] In this embodiment, the retaining ring 183 can be connected to the side of the fixing plate 18 facing the driving member 10 by bolts, or the retaining ring 183 is snap-fitted into a retaining ring groove (not marked in the figure) on the side of the fixing plate 18 facing the driving member 10, and specifically can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0116] After the bearing 20 is disposed in the bearing hole 181, the retaining ring 183 is disposed on the side of the fixing plate 18 facing the driving member 10. At this time, the retaining ring 183 is located around the bearing hole 181. Since the inner diameter of the retaining ring 183 is smaller than the outer diameter of the bearing 20, at this time, under the limiting action of the inner diameter portion of the retaining ring 183, the bearing 20 can be prevented from moving axially from the bearing hole 181 towards the driving member 10 side.

[0117] According to some embodiments of the present application, as Figure 8 shown, the conveyor line further includes a second belt 23 and a second pulley 24. Among them, the second belt 23 and the second pulley 24 are both disposed in the second housing 17, and the second pulley 24 can rotate relative to the second housing 17; at the same time, the second belt 23 is sleeved between the second rotating shaft 12 and the second pulley 24.

[0118] In this embodiment, both ends of the second pulley 24 are rotatably connected to opposite inner sides of the second housing 17 through rotating shafts, and the axial direction of the second pulley 24 is parallel to the axial direction of the second rotating shaft 12.

[0119] When the second rotating shaft 12 rotates, it can drive the second pulley 24 to rotate through the second belt 23. At this time, the second pulley 24 can be used to drive other components to rotate or move.
