Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and in particular to a battery transport system. Background Art

[0002] With the rapid development of the new energy industry, energy storage technology has been widely used. As an important energy storage device, the installation, stacking and replacement of internal batteries (usually "lithium battery packs") in battery cabinets (also called "energy storage cabinets") are complicated and arduous. Traditional manual operations are not only inefficient, but also pose safety risks. During the production process of battery cabinets, the produced batteries need to be pushed into the battery cabinets. Batteries of different models vary in size and weight. Manual operation is labor-intensive and improper operation can easily damage the batteries, which is dangerous.

[0003] For example, some large lithium battery packs used for industrial energy storage may weigh more than hundreds of kilograms or even more than one ton because they contain a large number of battery cells and necessary cooling and management systems. In such a scenario, the traditional manual handling method is very risky. Even if multiple people work together, the battery pack may be damaged or even cause a safety accident due to uneven strength or improper operation. Although the use of cranes for lifting is theoretically feasible, there are many inconveniences in actual operation. First, the operation of the crane requires professional technicians, and the lifting process requires precise control and coordination, which greatly increases the difficulty and time cost of operation. Secondly, the crane needs to repeatedly adjust its position and height during the lifting process to adapt to battery cabinets at different positions and heights, which not only wastes a lot of time, but also reduces work efficiency. More importantly, the flexibility of the crane is relatively poor and it is difficult to adapt to the complex and changeable battery installation environment.

During the entire transportation process, the battery basically only moves relative to the first transmission device and the second transmission device in the first direction, minimizing the movement range of the battery, achieving efficient automation of battery transportation, and improving production efficiency. Furthermore, the second transmission device can move between the first position and the second position as a whole, adapting to battery cabinets in different positions and different models, increasing the flexibility and applicability of the system.

[0029] Furthermore, the battery handling system also includes a propulsion mechanism. The propulsion mechanism is designed to push the battery to ensure that the battery is fully inserted into the battery cabinet. In a scenario where most of the battery has been inserted into the cabinet, due to the reduced contact area between the battery and the second transmission device, the thrust provided by the second transmission device may not be able to resist the friction between the cabinet and the battery, resulting in slippage between the second rail of the second transmission device and the battery. At this time, the propulsion mechanism assists in pushing the battery so that the battery continues to move toward the battery cabinet until the final entry task is completed.

[0030] Furthermore, the propulsion mechanism also includes a pressure sensor. The provision of the pressure sensor can prevent excessive thrust from damaging the battery, thereby ensuring the safety and reliability of the handling process.

[0031] Furthermore, through the coordination of the lifting structure and the translational structure, especially by setting a gantry structure for lifting batteries on the supporting platform, the load capacity of the battery handling system can be effectively increased, so that the battery handling system can be more widely used in the handling of heavy and large-size batteries.

[0041] As mentioned in the background art, the installation, stacking and replacement of batteries (usually "lithium battery packs") inside battery cabinets in the prior art are complicated and arduous, and traditional manual operations are not only inefficient but also pose safety risks.

[0042] To solve the above technical problems, an embodiment of the present invention provides a battery handling system for transporting batteries to a target position of a battery cabinet, the battery handling system comprising: a first transmission device, comprising a first rail for receiving batteries and transmitting the batteries along the first direction; a second transmission device, comprising a movable second rail for receiving batteries transported by the first transmission device and relaying the batteries to the target position, the second rail being able to move at least between a first position and a second position, the second rail at the first position being aligned with the first rail, the second rail at the second position being aligned with the target position, and the battery moving along the first direction under the transmission of the second rail; and a control module for controlling the second rail to move between the first position and the second position.

[0043] By adopting the technical solution of the present application, the battery is received by the first transmission device, and the battery is relayed by the movable second transmission device to transport the battery to the target position of the battery cabinet. During the entire transportation process, the battery basically only moves relative to the first transmission device and the second transmission device in the first direction, minimizing the movement range of the battery, achieving efficient automation of battery transportation, and improving production efficiency. Furthermore, the second transmission device can move between the first position and the second position as a whole, adapting to battery cabinets in different positions and different models, increasing the flexibility and applicability of the system.

[0044] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] Figure 1 FIG. 1 is a schematic diagram of a battery handling system 100 according to an embodiment of the present invention.

[0046] refer to Figure 1The battery handling system 100 can be used to carry the battery 200 to the target position of the battery cabinet 300. The battery handling system 100 includes: a first transmission device 1, including a first rail 11 for receiving the battery 200 and transmitting the battery 200 along the first direction D1; a second transmission device 2, including a movable second rail 21, for receiving the battery 200 transported by the first transmission device 1 and relaying the battery 200 to the target position, the second rail 21 can at least move between a first position and a second position, the second rail 21 located at the first position is aligned with the first rail 11, and the second rail 21 located at the second position is aligned with the target position, and the battery 200 moves along the first direction D1 under the transmission of the second rail 21; a control module 3, for controlling the second rail 21 to move between the first position and the second position.

[0047] Specifically, the battery 200 may be, for example, a single battery cell with a large volume or a large weight. Alternatively, the battery 200 may also be, for example, a battery pack, which may generally include a plurality of battery cells, which may be connected in series, for example. Compared with a single battery cell, a battery pack generally has a larger volume and a larger weight.

[0048] In practical applications, the weight of the battery 200 may be, for example, 100-800 kg (kilograms).

[0049] In some embodiments, in combination Figure 1 and Figure 2 The first transport device 1 may include a first rail 11 , and the battery 200 can be transported along the first direction D1 under the transportation of the first rail 11 .

[0050] The first direction D1 may be roughly the connection direction from the battery 200 receiving position of the battery handling system 100 to the battery cabinet 300. Figure 1 The battery handling system 100 receives the battery 200 through the first rail 11, and the battery cabinet 300 is located on the side of the battery handling system 100 away from the first rail 11. The direction in which the first rail 11 points to the battery cabinet 300 can be recorded as the first direction D1, and the first rail 11 (and the second rail 21 described below) extend along the first direction D1.

[0051] In some embodiments, along the first direction D1, the first rail 11 includes an initial end 101 and a docking end 102. The battery 200 can be placed at the initial end 101 and moved toward the docking end 102.

[0052] In some embodiments, the battery 200 can be placed at the initial end 101 by a mechanical structure such as a crane or a hoist.

[0053] In some embodiments, the first transmission device 1 further includes a centering mechanism 12. The centering mechanism 12 may be disposed on two opposite sides of the first rail 11 along the second direction D2. The second direction D2 is perpendicular to the first direction D1.

[0054] Furthermore, compared with the docking end 102, the centering mechanism 12 is disposed closer to the initial end 101. Thus, the centering mechanism 12 can adjust the position of the battery 200 located at the initial end 101 so that the extension direction of the battery 200 is substantially parallel to the extension direction of the first rail 11 (i.e., the first direction D1), so as to avoid collision with other structures of the first transmission device 1 during transportation, thereby causing damage to the battery.

[0055] Furthermore, the first transport device 1 may further include a blocking structure 13, which is disposed at a position of the first rail 11 near the docking end 102. When the first transport device 1 and the second transport device 2 are not aligned, that is, when the first rail 11 and the second rail 21 are not docked, at least a portion of the blocking structure 13 is located in front of the battery 200 along the first direction D1. When the first rail 11 and the second rail 21 are successfully docked, the blocking structure 13 can be stored below the first rail 11 along the gravity direction G to avoid the transmission process of the battery 200 along the first direction D1.

[0056] In some embodiments, the first transmission device 1 may further include a lifting mechanism 14. The lifting mechanism 14 is used to lift or drop the battery 200 so that the battery 200 is separated from the first rail 11 or placed on the first rail 11. Further, the lifting mechanism 14 is disposed at a position of the first rail 11 close to the initial end 101. The battery 200 located at the initial end 101 is placed above the lifting mechanism 14 along the gravity direction G.

[0057] In an actual application scenario, before the battery 200 contacts the first rail 11, the lifting mechanism 14 may be in a raised state. The lifting mechanism 14 in the raised state may extend out of the transport surface formed by the first rail 11 in the opposite direction of the gravity direction G. The battery 200 may be placed on the lifting mechanism 14, and at this time, there is no actual contact between the battery 200 and the first rail 11. Further, the first transmission device 1 may also be provided with an incoming material detection device for detecting the position of the battery 200. In response to the incoming material detection device detecting that the battery 200 is successfully placed on the lifting mechanism 14, the lifting mechanism 14 may fall in the direction of gravity so that the battery 200 is placed at the initial end 101 of the first rail 11. In this process, the centering mechanism 12 may push the battery 200 and adjust the orientation of the battery 200. Further, after the centering mechanism 12 is adjusted, the first power unit 16 of the first transportation device 1 is started to operate the first rail 11 and thus realize the transmission of the battery 200.

[0058] In some embodiments, the first rail 11 may be a transmission structure such as a transmission chain or a crawler belt.

[0059] Furthermore, corresponding to the alignment of the first rail 11 and the second rail 21 of the second transport device 2 , the blocking mechanism 13 is retracted to avoid the transport travel of the battery 200 on the first rail 11 .

[0060] Furthermore, the battery 200 is transported by the first rail 11 and moves from the initial end 101 to the docking end 102. Furthermore, the first rail 11 continues to operate, thereby transferring the battery 200 to the second rail 21.

[0061] In some embodiments, the second rail 21 starts to operate after being aligned with the first rail 11 to receive the battery 200 conveyed by the first rail 11. Further, the second rail 21 relays the battery 200 to the target position of the battery cabinet 300.

[0062] Furthermore, after receiving the battery 200 , the second rail 21 continues to transport the battery 200 toward the target position along the first direction D1 . The movement direction of the battery 200 on the second rail 21 is consistent with the movement direction of the battery 200 on the first rail 11 .

[0063] In some embodiments, in combination Figures 1 to 3 , the second rail 21 may extend along the first direction D1. Along the first direction D1, the second rail 21 may include a receiving end 201 and a cabinet entry end 202 relative to each other. Further, the second rail 21 may be able to move between a first position and a second position. When the second rail 21 is located at the first position, the receiving end 201 is aligned with the docking end 102 of the first rail 11, and the battery 200 is transferred from the docking end 102 to the second rail 21 through the receiving end 201. When the second rail 21 is located at the second position, the cabinet entry end 202 is aligned with the target position on the battery cabinet 300, and the battery 200 enters the battery cabinet 300 through the cabinet entry end 202.

[0064] In some embodiments, continue to refer to Figure 1 , the control module 3 can be independent of the first transportation device 1 and the second transportation device 2 .

[0065] In some embodiments, the control module 3 may also be disposed in one of the first transportation device 1 and the second transportation device 2 .

[0066] Furthermore, the control module 3 is at least used to control the second rail 21 to move between the first position and the second position when a preset condition is met.

[0067] For example, in response to the battery 200 being placed on the first rail 11, the control module 3 may control the second rail 21 to move to the first position, and the receiving end 201 of the second rail 21 is aligned with the docking end 102 of the first rail 11. For another example, in response to the battery 200 being transferred to the second rail 21, the control module 3 may control the second rail 21 to move to the second position, and the cabinet entry end 202 of the second rail 21 is aligned with the target position of the battery cabinet 300.

[0068] In some embodiments, the battery cabinet 300 can be divided into a plurality of storage compartments in an array along the gravity direction G and the second direction D2, wherein each storage compartment can serve as a target position for the second rail 21 to dock with to receive and store the battery 200.

[0069] In some embodiments, in combination Figures 3 to 5 The battery handling system 100 may further include a propulsion mechanism 4. The propulsion mechanism 4 is disposed on the second rail 21. The propulsion mechanism 4 may be used to push the battery 200 along the first direction D1 so that the battery 200 completely enters the battery cabinet 300.

[0070] Further, in response to detecting that the battery 200 is transported to the first preset position on the second rail 21, the control module 3 drives the propulsion mechanism 4 to switch from the first state to the second state. In the first direction D1, the battery 200 at the first preset position is closer to the cabinet entry end 202 than the receiving end 201.

[0071] Furthermore, along the first direction D1, the battery 200 at the first preset position is located in front of the propulsion mechanism 4. When the propulsion mechanism 4 switches from the first state to the second state, the projection of the propulsion mechanism 4 along the first direction D1 and the projection of the battery 200 along the first direction D1 at least partially overlap.

[0072] In a typical application scenario, when most of the battery 200 has been put into the cabinet, the thrust power provided by the second rail 21 gradually decreases due to the decrease in the contact area between the remaining part of the battery 200 and the second rail 21, until it is less than or equal to the resistance encountered by the battery 200 when entering the battery cabinet 300. At this time, since the thrust cannot overcome the resistance, the battery 200 and the second rail 21 may slip, so that the battery 200 cannot completely enter the target position of the battery cabinet 300. Among them, the thrust provided by the second rail 21 can be, for example, the friction between the second rail 21 and the battery 200. The resistance encountered by the battery 200 when entering the battery cabinet 300 can be, for example, the friction between the battery 200 and the cabinet body (for example, a partition) of the battery cabinet 300 forming the target position. As the battery 200 leaves the second rail 21 and enters the target position of the battery cabinet 300, the pressure from the battery 200 on the second rail 21 gradually decreases, and the friction between the battery 200 and the second rail 21 also decreases accordingly. Accordingly, the pressure from the battery 200 on the battery cabinet 300 to form the target position cabinet gradually increases, and the friction between the battery 200 and the cabinet also increases. When the friction between the battery 200 and the second rail 21 is not enough to overcome the friction between the battery 200 and the cabinet, the battery 200 cannot continue to enter the cabinet.

[0073] In the above application scenario, the propulsion mechanism 4 can continue to provide thrust to the battery 200 to ensure that the battery 200 is completely placed in the cabinet, to prevent the battery 200 from accidentally falling and being damaged due to a local area still being located outside the battery cabinet 300 after the second rail 21 is evacuated.

[0074] In some embodiments, the propulsion mechanism 4 is capable of switching between a first state and a second state, wherein the propulsion mechanism 4 in the first state avoids the transportation journey of the battery 200 on the second rail 21, and at least a portion of the propulsion mechanism 4 in the second state moves from the rear of the battery 200 along the first direction D1 toward the battery cabinet 300 to push the battery 200.

[0075] Furthermore, along a direction perpendicular to the first direction D1 , the second rail 21 has a first side 211 and a second side 212 opposite to each other, and the propulsion mechanism 4 in the first state is accommodated in the first side 211 and / or the second side 212 .

[0076] Specifically, refer to Figure 3 The propulsion mechanism 4 can be respectively disposed on the first side 211 and the second side 212. Thus, when the battery 200 is pushed into the cabinet, the thrust applied to the battery 200 is more uniform, thereby preventing the movement direction of the battery 200 from deviating from the first direction D1.

[0077] further, Figure 32 shows a schematic diagram of the propulsion mechanism 4 in the first state and the second state. The propulsion mechanism 4 arranged on the first side 211 is in the first state, and the propulsion mechanism 4 arranged on the second side 212 is in the second state. It should be understood that Figure 3 The state of the propulsion mechanism 4 in the figure is only exemplary. In a common usage scenario, the propulsion mechanism 4 located at the first side 211 and the propulsion mechanism 4 located at the second side 212 maintain the same state.

[0078] further, Figure 4 The propulsion mechanism 4 is in the first state, Figure 5 The propulsion mechanism 4 is in the second state.

[0079] Further, combined with Figure 4 and Figure 5 The propulsion mechanism 4 includes: at least one push rod assembly 41, which is arranged on at least one side of the first side 211 and the second side 212; a moving part 42, which is connected to the push rod assembly 41, and the moving part 42 is used to drive the push rod assembly 41 to switch between the first state and the second state.

[0080] In some embodiments, the moving portion 42 may also be used to drive the push rod assembly 41 to move along the first direction D1 in the second state.

[0081] In some embodiments, the moving part 42 may include a driving motor to simultaneously drive the push rod assembly 41 to switch between the first state and the second state, and to drive the push rod assembly 41 to move along the first direction D1 in the second state.

[0082] In some embodiments, the moving part 42 may also include two independent driving motors, which respectively drive the push rod assembly 41 to switch between the first state and the second state, and drive the push rod assembly 41 to move along the first direction D1 in the second state.

[0083] Further, the push rod assembly 41 may include: a connecting rod 411, having a connecting end 4111 and a free end 4112 relative to each other along the extension direction, wherein the connecting end 4111 is hinged to one of the first side 211 and the second side 212; a propulsion portion 412, arranged at the free end 4112, and the propulsion portion 412 in the second state contacts and pushes the battery 200.

[0084] In some embodiments, the propulsion mechanism 4 may further include a third guide portion 44 extending along the first direction D1 and a third sliding portion 45 movably connected to the third guide portion 44. Further, the connecting end 4111 of the connecting rod 411 may be hinged to the third sliding portion 45. Further, the third sliding portion 45 may move along the first direction D1 under the guidance of the third guide portion 44.

[0085] In some embodiments, the connecting rod 411 in the first state may extend in a direction parallel to the gravity direction G, extending from the third sliding portion 45 in a direction opposite to the gravity direction G. The propulsion portion 412 may extend in a direction parallel to the first direction D1. Thus, the push rod assembly 41 may be prevented from interfering with the transportation of the battery 200 on the second rail 21.

[0086] In some embodiments, the propulsion portion 412 may also be in the shape of a rod. Thus, under the premise that the length of the third guide portion 44 remains unchanged, the propulsion mechanism 4 can push the battery 200 to move a greater distance.

[0087] Furthermore, under the drive of the moving part 42 , the connecting rod 411 can rotate in a plane perpendicular to the first direction with the connecting end 4111 as the center to switch to the second state.

[0088] Further, the propulsion mechanism 4 in the second state can refer to Figure 5 The extending direction of the connecting rods 411 in each set of push rod assemblies 41 may be parallel to the second direction D2.

[0089] Furthermore, in the propulsion mechanism 4 in the second state, the end of the propulsion portion 412 away from the connecting rod 411 can be abutted against the end surface of the battery 200 that is away from the first direction D1. Furthermore, as the moving portion 42 drives the third sliding portion 45 to continue to move in the first direction D1 along the third guiding portion 44, the propulsion portion 412 pushes the battery 200 to move in the first direction D1.

[0090] In some embodiments, continue to refer to Figure 4 and Figure 5 The propulsion mechanism 4 may further include: a pressure sensor 43, for collecting the force between the propulsion mechanism 4 and the battery 200, the pressure sensor 43 communicates with the control module 3, and in response to the collected value of the force being greater than a preset threshold, the control module 3 controls the propulsion mechanism 4 to stop moving.

[0091] In some embodiments, the preset threshold may be, for example, 3000-10000 N (Newton).

[0092] In practical applications, the pressure sensor 43 can be provided at the push rod assembly 41. More specifically, the pressure sensor 43 can be provided at one end of the push portion 412 close to the connecting rod 411. Further, in the process of the push mechanism 4 pushing the battery 200 in the second state, the pressure sensor 43 can collect the real-time reaction force of the push portion 412 on the battery 200, and determine the travel state of the battery 200 by the numerical value of the reaction force. For example, the battery 200 may be stuck in the process of entering the battery cabinet 300. At this time, the reaction force value of the battery 200 acting on the push portion 412 collected by the pressure sensor 43 increases. If the battery 100 continues to be pushed, it may cause damage to the battery 100. At this time, it is necessary to stop pushing the battery 200 first, manually adjust the position or direction of the battery 200, and then continue to push the battery 200, and finally complete the battery 200 into the cabinet. Therefore, through the real-time detection of the pressure sensor 43, the battery 200 can be effectively protected to avoid being squeezed and damaged by the battery 200 due to jamming and other situations during the transportation process.

[0093] In some embodiments, reference Figure 3 The battery handling system 100 may further include: a position detection module 5, which communicates with the control module 3, and the position detection module 5 is used to obtain the position of the battery 200. The control module 3 controls the working state of the first rail 11 and / or the second rail 21 according to the detection result of the position detection module 5.

[0094] In a specific embodiment, in response to the detection result indicating that the battery 200 reaches the second preset position on the second rail 21, the control module 3 controls the second rail 21 to stop working, wherein the projection of the battery 200 located at the second preset position along the gravity direction G does not overlap with the first transport device 1. The battery 200 located at the second preset position is completely separated from the first transport device 1 (specifically, the first rail 11).

[0095] Further, when the actual position of the battery 200 obtained by the position detection module 5 is at the second preset position, the second rail 21 stops working and the battery 200 remains at the second preset position. Further, the second rail 21 can move from the first position to the second position. During the movement of the second rail 21 between the first position and the second position, the transport component of the second rail 21 (such as a track, a chain, etc.) always remains stationary to prevent the battery 200 from accidentally falling off and causing damage.

[0096] Further, along the gravity direction G, the projection of the battery 200 at the second preset position is located on the transport surface of the second rail 21 .

[0097] In some embodiments, a limiting mechanism 213 is further provided on the second rail 21 , and the limiting mechanism 213 is used to limit the relative movement between the battery 200 and the second rail 21 when the second rail 21 moves between the first position and the second position.

[0098] Further, the limiting mechanism 213 may be disposed at at least one end of the second rail 21 along the first direction D1 .

[0099] In some non-limiting embodiments, the number of the limiting mechanisms 213 can be two, which are respectively arranged near the receiving end 201 and the cabinet entry end 202. After the battery 200 is completely received by the second rail 21, the limiting mechanism 213 can at least partially extend out of the transport surface of the second rail 21. Along the first direction D1, the two limiting mechanisms 213 can be located on both sides of the battery at the second preset position. In this way, the battery 200 can be prevented from accidentally falling during the movement of the second rail 21 between the first position and the second position.

[0100] In some embodiments, the second rail 21 moves between the first position and the second position along a second direction D2 and / or a gravity direction G, and the first direction D1 , the second direction D2 and the gravity direction G are perpendicular to each other.

[0101] For example, when the target position on the battery cabinet 300 and the transport surface of the first rail 11 are at the same height, the second rail 21 can move along the second direction D2 without moving along the gravity direction G. When there is a height difference between the target position on the battery cabinet 300 and the transport surface of the first rail 11, the second rail 21 also needs to move along the gravity direction G to achieve movement between the first position and the second position.

[0102] Further, combined with Figure 1 , Figure 6 and Figure 7 The second transmission device 2 further includes: a position adjustment mechanism 22, which is used to move the second rail 21 along the second direction D2 and the gravity direction G. As a result, the second rail 21 can move from the first position to the second position more quickly, thereby accelerating the efficiency of the battery 200 entering the cabinet.

[0103] Specifically, the position adjustment mechanism 22 may include: a lifting structure 221, used to lift or lower the second rail 21 along the gravity direction G; a translation structure 222, used to move the second rail 21 along the second direction D2, and the lifting structure 221 and the second rail 21 are supported by the translation structure 222. Therefore, through the cooperation of the lifting structure 221 and the translation structure 222, the battery handling system 100 can adapt to different types of battery cabinets 300, and more flexibly realize the operation of placing the battery 200 into the cabinet.

[0104] Further, refer to Figure 6 The lifting structure 221 includes: a gantry structure 2211, which is supported by the translation structure 222 and can move along the extension direction of the translation structure 222, the gantry structure 2211 includes a pair of supporting walls 22111 arranged opposite to each other, and at least one side of the second rail 21 along the second direction D2 is movably connected to the adjacent supporting wall 22111.

[0105] In some embodiments, an assembly flange is formed at one end of the support wall 22111 facing the gravity direction G. The assembly flange can be fixedly connected to the translation structure 222 by a fixing member. The fixing member can be, for example, a bolt, a screw, etc.

[0106] In some embodiments, the lifting structure 221 also includes: a first guide portion 2212, which is arranged on at least one of the pair of support walls 22111; a first sliding portion 2213, which is movably connected to the first guide portion 2212, and the first sliding portion 2213 can reciprocate along the gravity direction G and the opposite direction under the guidance of the first guide portion 2212, and the second rail 21 is connected to the gantry structure 2211 through the first sliding portion 2213.

[0107] Continue to refer Figure 6 A pair of supporting walls 22111 of the gantry structure 2211 may be provided with a first guide portion 2212 and a first sliding portion 2213. Thus, it is possible to ensure that the second rail 21 is more stable during the lifting process.

[0108] Furthermore, the first guide portion 2212 may be disposed on surfaces of a pair of support walls 22111 that are opposite to each other.

[0109] Furthermore, the first sliding portion 2213 can move up and down along the gravity direction G under the guidance of the first guiding portion 2212 .

[0110] In some non-limiting embodiments, the movement states of the two first sliding portions 2213 disposed on a pair of supporting walls 22111 are the same.

[0111] In some non-limiting embodiments, the first sliding portion 2213 may be, for example, in the shape of a flat plate, thereby increasing the contact area between the second rail 21 and the first sliding portion 2213 and improving the stability of the connection.

[0112] In some embodiments, in combination Figure 1 , Figure 6 and Fig. 9The lifting structure 221 may further include: a bearing portion 2214 disposed between the pair of supporting walls 22111 , the bearing portion 2214 being used to bear the second rail 21 , the bearing portion 2214 being connected to the first sliding portion 2213 and moving with the first sliding portion 2213 .

[0113] Furthermore, the bearing portion 2214 includes a support frame 22142 , and the second rail 21 can be supported on the support frame 22142 .

[0114] Furthermore, the bearing portion 2214 may further include a plurality of connecting members 22141 , which are dispersedly disposed on two sides of the support frame 22142 along the second direction D2 . The bearing portion 2214 is connected to the corresponding first sliding portion 2213 through the connecting members 22141 .

[0115] In some embodiments, the lifting structure 221 may further include a second power unit 2215 , and the second power unit 2215 may drive the first sliding unit 2213 to move up and down along the gravity direction G through a transmission structure such as a chain or a crawler track.

[0116] In some embodiments, the lifting structure 221 may further include an anti-falling structure 2216. The anti-falling structure 2216 may be disposed on the first sliding portion 2213 to prevent the second rail 21 from accidentally falling during the lifting process of the second rail 21 and causing an operation accident.

[0117] In some embodiments, in combination Figure 1 , Figure 6 and Figure 7 The translation structure 222 includes: a support platform 2221; a second guide portion 2222, which is arranged on the support platform 2221; a second sliding portion 2223, which is movably connected to the second guide portion 2222, and the second sliding portion 2223 can reciprocate along the second direction D2 under the guidance of the second guide portion 2222, and the lifting structure 221 is supported on the second sliding portion 2223.

[0118] In some embodiments, the translation structure 222 may include a plurality of anchor structures, which are dispersedly arranged on the side of the support platform 2221 facing the gravity direction G. In practical applications, the anchors of the translation structure 222 may be pre-fixed to the ground or the construction plane. In this way, the stability of the battery 200 transportation can be maintained, and the risk of tipping over due to the upward movement of the center of gravity of the second transmission device 2 and the battery 200 as a whole when the battery 200 is lifted too high can be avoided.

[0119] In some embodiments, a pair of side walls of the support platform 2221 can be used to form the second guide portion 2222. The second sliding portion 2223 is located between a pair of side walls of the support platform 2221 along the first direction D1, and the channel formed by the pair of side walls of the support platform 2221 is used to guide the second sliding portion 2223 to move along the second direction D2.

[0120] In an actual application scenario, the load of the translation structure 222 can reach 5 tons, and the load of the lifting structure 221 can reach 3 tons. Therefore, the battery handling system 100 can handle the handling scenario of heavy batteries 200.

[0121] In some embodiments, a surface of the second sliding portion 2223 that is away from the gravity direction G forms a support surface. The lifting structure 221 may be supported by the second sliding portion 2223 .

[0122] Specifically, combined Figure 1 , Figure 6 and Figure 7 , a pair of side walls 22111 of the gantry structure 2211 of the lifting structure 221 can be connected to the second sliding part 2223. More specifically, one end of the side walls 22111 facing the gravity direction G can be fixedly connected to the second sliding part 2223 by a fixing member (such as a bolt, a screw, etc.). Thus, it can be ensured that the lifting structure 221 reciprocates along with the second sliding part 2223 in the second direction D2.

[0123] In some embodiments, in combination Figure 1 , Figure 8 and Fig. 9 The position adjustment mechanism 22 may further include: a telescopic structure 8 for moving the second rail 21 along the first direction D1 to reduce the gap between the second rail 21 located at the second position and the target position and / or reduce the gap between the second rail 21 located at the first position and the first rail 11.

[0124] In a typical application scenario, when the lifting structure 211 and the translation structure 212 cooperate to align the second rail 21 with the docking end 102 of the first rail 11 along the second direction D2 and the gravity direction G, the telescopic structure 8 can drive the second rail 21 to further move toward the first rail 11 along the first direction D1 to reduce the distance between the docking end 102 and the receiving end 201, ensuring that the second rail 21 can smoothly receive the battery 200. With the movement of the second rail 21, when the lifting structure 211 and the translation structure 212 cooperate to align the second rail 21 with the target position of the battery cabinet 300 along the second direction D2 and the gravity direction G, the telescopic structure 8 can drive the second rail 21 to further move toward the target position along the first direction D1 to reduce the distance between the cabinet entry end 202 and the target position, ensuring that the battery 200 can be smoothly entered into the cabinet.

[0125] Furthermore, the telescopic structure 8 may be disposed between the second rail 21 and the bearing portion 2214 .

[0126] In a specific embodiment, the telescopic structure 8 may include a fourth guide portion 81 and a fourth sliding portion 82 that can move relative to the fourth guide portion 81 .

[0127] Furthermore, the bearing portion 2214 may include a coupling portion 87 , and the coupling portion 87 is used to connect the fourth sliding portion 82 so that the bearing portion 2214 and the fourth sliding portion 82 move synchronously.

[0128] Further, the fourth sliding portion 82 may include, for example, a plurality of sliding blocks. The coupling portion 87 may include a plurality of protrusions, and the plurality of sliding blocks correspond to the plurality of protrusions one by one. Further, the corresponding sliding blocks and protrusions may be fixedly connected.

[0129] Furthermore, the telescopic structure 8 may further include a fourth power unit 83. The fourth power unit 83 may include a rotatable output shaft 84, and the output shaft 84 may extend along the first direction D1.

[0130] Furthermore, the second rail 21 has a support frame on one side facing the gravity direction G, for increasing the structural strength of the second rail 21. Both ends of the output shaft 84 along the first direction D1 are fixed to the support frame of the second rail 21, respectively.

[0131] Furthermore, the telescopic structure 8 further includes a connecting slider 85 movably disposed on the output shaft 84 . Along the first direction D1 , the connecting slider 85 can move along the first direction D1 under the driving of the output shaft 84 .

[0132] Furthermore, the connecting slider 85 is fixedly connected to the matching portion 86 on the bearing portion 2214. Thus, through the output shaft 84 and the connecting slider 85, the second rail 21 can move relative to the bearing portion 2214 along the first direction D1 to get closer to the first rail 11 or the battery cabinet 300.

[0133] In some embodiments, in combination Figure 8 and Fig. 9 , along the first direction D1, both ends of the fourth guide portion 81 may further be provided with limiting portions 88. The limiting portions 88 are used to limit the maximum displacement of the fourth sliding portion 82 relative to the fourth guide portion 81, that is, the maximum displacement of the second rail 21 relative to the bearing portion 2214.

[0134] Furthermore, the bearing portion 2214 may also be provided with a stop portion 89 corresponding to the limit portion 88. When the second rail 21 moves to the farthest point relative to the bearing portion 2214 (i.e., the point closest to the first rail 11 or the target position), the stop portion 89 may abut against the limit portion 88 to prevent the second rail 21 from continuing to move toward the first rail 11 or the target position and causing an accidental collision.

[0135] In some embodiments, reference Figure 3 The battery handling system 100 may further include: an alignment module 6, which is at least arranged at one end of the second transmission device 2 facing the battery cabinet 300, and the alignment module 6 is used to obtain the alignment status of the target position of the second rail 21 and the battery cabinet 300. In response to the second rail 21 being aligned with the target position, the control module 3 controls the second transmission device 2 to stop moving.

[0136] In some embodiments, the alignment module 6 may also be disposed at one end of the second transport device 2 facing the first rail 11 to obtain an alignment status of the second rail 21 and the first rail 11 .

[0137] In some embodiments, the alignment module 6 can be, for example, a 2D camera, which completes the precise docking of the second rail 21 and the first rail 11 or the target position through processes such as 2D camera photography, optical imaging, digital image processing, and PLC (Programmable Logic Controller) control program feedback.

[0138] In some embodiments, in combination Figure 1 , Figure 6 and Fig. 9 The battery handling system 100 may further include: a leveling mechanism 7, which is arranged on the second conveying device 2, and the leveling mechanism 7 is used to adjust the angle of the conveying surface of the second rail 21 relative to the horizontal plane, so that the conveying surface of the second rail 21 located at the first position is flush with the conveying surface of the first rail 11 and / or the conveying surface of the second rail 21 located at the second position is flush with the surface where the target position of the battery cabinet 300 is located.

[0139] Specifically, the leveling mechanism 7 can be arranged at the four corners of the bearing portion 2214, and the angle between the support surface of the bearing portion 2214 and the horizontal plane is adjusted by changing the vertical heights of the four corners of the bearing portion 2214, thereby adjusting the angle between the transport surface of the second rail 21 and the horizontal plane. In this way, when the second rail 21 is aligned with the first rail 11 or the target position, the transport surface of the second rail 21 can also be flush with the transport surface of the first rail 11 or the surface where the target position is located.

[0140] In some embodiments, each of the first power unit 16, the second power unit 2215, the third power unit 2224 and the fourth power unit 83 can be driven by a servo gear rack to drive the corresponding structure to move along the corresponding track.

[0141] From the above, the technical solution of the present application is adopted, the battery 200 is received by the first transmission device 1, and the battery 200 is relayed and transported to the target position of the battery cabinet 300 by the movable second transmission device 2. During the entire transportation operation, the battery 200 basically only has relative movement in the first direction D1 relative to the first transmission device 1 and the second transmission device 2, which minimizes the movement range of the battery 200, realizes efficient automation of the transportation of the battery 300, and improves production efficiency. Furthermore, the second transmission device 2 can move between the first position and the second position as a whole, adapting to battery cabinets 300 of different positions and different models, increasing the flexibility and applicability of the system.

[0142] Furthermore, the battery handling system 100 also includes a propulsion mechanism 4. The propulsion mechanism 4 is designed to push the battery 200 to ensure that the battery 200 completely enters the battery cabinet 300. For example, in a scenario where most of the battery 200 has been placed in the cabinet, since the contact area between the battery 200 and the second transmission device 2 becomes smaller, the thrust provided by the second transmission device 2 is likely to be unable to resist the friction between the cabinet and the battery 200, resulting in slippage between the second rail 21 of the second transmission device 2 and the battery 200. At this time, the propulsion mechanism 4 assists in pushing the battery 200, so that the battery 200 continues to move toward the battery cabinet 300 until the final cabinet entry task is completed.

[0143] Furthermore, the propulsion mechanism 4 further includes a pressure sensor 43. The provision of the pressure sensor 43 can prevent the battery 200 from being damaged by excessive thrust, thereby ensuring the safety and reliability of the transport process.

[0144] Furthermore, through the coordination of the lifting structure 221 and the translation structure 222, especially by setting a gantry structure 2211 for lifting the battery 200 on the support platform 2221, the load capacity of the battery handling system 100 can be effectively increased, so that the battery handling system 100 can be more widely used in the handling of heavy and large-sized batteries 200.
