Description

Technical Field

[0001] The present application relates to the technical field of auxiliary equipment for new energy energy storage devices, and particularly relates to a stacker for lithium battery PACK cabinets. Background Art

[0002] With the rapid development of the new energy industry, energy storage technology has been widely applied. As an important energy storage device, during the production process of an energy storage cabinet, it is necessary to push the produced lithium battery PACK into the energy storage cabinet. The lithium battery PACK is generally assembled by multiple battery packs, and a battery management system, etc. is also added. It is the product finally provided by the battery factory to users. The size and weight of the lithium battery PACK vary. The installation, stacking, and replacement of lithium battery PACKs inside the energy storage cabinet are complex and heavy. Traditional manual operation not only has a high labor intensity and low efficiency, but also is prone to damaging the battery if operated improperly, and has a certain degree of danger.

[0003] Therefore, some auxiliary equipment for lithium battery PACK cabinets has emerged on the market, and the common forms are as follows:

[0004] (1) Using a counterbalanced forklift to assist the PACK into the cabinet.

[0005] (2) Using a fully automatic AGV auxiliary cabinet system, which is further divided into a mobile AGV system and a rail AGV system.

[0006] Although these forms of PACK auxiliary cabinet systems can all achieve the entry of the PACK into the cabinet, they all have certain defects.

[0007] The main disadvantages of the first method are mainly relying on the operating experience of the forklift driver, requiring several people to cooperate, the cabinet entry effect is unstable, and there is a risk of damaging the battery. It is not applicable to some special battery packs and special cabinet entry positions, and manual cabinet entry operation is still required.

[0008] The second method is a fully automatic cabinet entry method, and its disadvantages are high cost, large one-time investment, low cabinet entry efficiency of the automatic cabinet entry system, high requirements for the use environment and operating personnel, relatively high requirements for the standardization degree and types of energy storage cabinets, and poor adaptability. It is suitable for mass production and not applicable to small batch and multi-type production. In addition, the rail fully automatic AGV cabinet entry system also has the disadvantage of difficult equipment movement. The cabinet entry accuracy depends on various sensors and vision algorithm systems. Once there is any abnormality in the middle, the entire system stops running; the fully automatic cabinet entry system has a complex structure, requires a large use space, high procurement cost, high requirements for the ground flatness, because of the high requirements for positioning accuracy, the positioning system is complex, and the overall system cabinet entry efficiency is average.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0081] In the description of this specification, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0082] The embodiment of the present application provides a lithium battery PACK cabinet stacker, which can cooperate with a lifting device to complete the operation of putting the lithium battery PACK into the cabinet.

[0083] As Figure 1 and Figure 2 shown, where Figure 1 is the front view of the lithium battery PACK cabinet stacker provided by the embodiment of the present application, Figure 2 is its top view.

[0084] The lithium battery PACK cabinet stacker includes: a vehicle body 1; a traveling mechanism is provided at the bottom of the vehicle body 1; a carrier system 2, a gantry system 3, a control system 5, and a drive system 4 are sequentially arranged on the vehicle body 1 from front to rear. Among them:

[0085] The carrier system 3 is used to carry the lithium battery PACK to be put into the cabinet;

[0086] The drive system 4 is used to drive the traveling mechanism to drive the vehicle body 1 to move and turn;

[0087] The control system 5 is used to control the gantry system 3 to drive the carrier system 2 to move after the vehicle body 1 moves to the cabinet platform, and push the lithium battery PACK into the energy storage cabinet.

[0088] The following will combine Figures 3 to 7 to make a detailed description of each part of the lithium battery PACK cabinet stacker of the embodiment of the present application. Among them, Figure 3 and Figure 4 show a structure of the gantry system in the lithium battery PACK cabinet stacker; Figure 5 and Figure 6 show the front and rear structures of the vehicle body of the lithium battery PACK cabinet stacker; Figure 7 show a structure of the drive system in the lithium battery PACK cabinet stacker.

[0089] At the same time, referring to the above structural diagrams, the structural details of the lithium battery PACK cabinet stacker of the embodiment of the present application will be described in detail.

[0090] In the embodiment of the present application, the gantry system 3 includes: a gantry oil cylinder 18, an outer gantry 19, an inner gantry 20, a carriage 22, and a carriage drive mechanism. Among them:

[0091] The outer gantry 10 is fixed on the vehicle body 1, for example, welded to the vehicle body 1 or integrally formed with the vehicle body 1, and the embodiment of the present application does not limit this;

[0092] The inner gantry 20 is located inside the outer gantry 10, and can be connected to the outer gantry 10 through rollers 21 or sliders, for example, and can be driven to move up and down by the gantry oil cylinder 18;

[0093] The carriage 22 is installed on the inner gantry 20. For example, rollers are installed on the inner gantry 20 to connect the carriage 22, and the carriage 22 is connected to the gantry oil cylinder 18 through a chain 23. The carriage 22 is used to fix the carrier system and can slide inside the inner gantry 20 under the drive of the gantry oil cylinder 18. Specifically, when the gantry oil cylinder 18 rises, the chain 23 pulls the carriage 22, causing the carriage 22 to slide up along the inner gantry 20; conversely, when the gantry oil cylinder 18 descends, the chain 23 pulls the carriage 22, causing the carriage 22 to slide down along the inner gantry 20.

[0094] The carriage drive mechanism includes: a drive oil cylinder, a pitching mechanism 24, and a side shifting mechanism 25. Among them, the pitching mechanism 24 and the side shifting mechanism 25 are installed on the carriage 22. The drive oil cylinder includes a first oil cylinder connected to the pitching mechanism and a second oil cylinder connected to the side shifting mechanism, and the first oil cylinder and the second oil cylinder are connected to the gantry oil cylinder 18 through a pipeline 26.

[0095] The first oil cylinder provides tilting power to the pitching mechanism 24, driving the carriage 22 to perform pitching motion, that is, to flip around the tilting axis in the front-rear direction. For example, the maximum flipping angle can be set. Correspondingly, the carriage 22 drives the vehicle system to perform pitching motion.

[0096] The second oil cylinder provides lateral movement power to the side-shifting mechanism 25, pushing the carriage 22 to move in the left-right direction, thereby driving the vehicle system to move left and right.

[0097] The side-shifting mechanism drives the carriage to perform side-shifting motion based on the power provided by the driving oil cylinder.

[0098] It should be noted that the power of the hydraulic mechanism in the lithium battery PACK cabinet stacker of the embodiment of the present application comes from the proportional valve hydraulic system in the vehicle body system, and is connected to each hydraulic actuator through corresponding pipelines. Each hydraulic actuator is uniformly controlled by the control system (such as a PLC control system).

[0099] In some embodiments, the vehicle system may include: a posture adjustment base plate 38, a rotation mechanism 27, a pushing mechanism, an electric actuator 51, and a servo motor 52. Among them: the rotation mechanism 27 is installed on the carriage 22; the posture adjustment base plate 38 is installed on the rotation mechanism 27; the pushing mechanism is arranged on the vehicle body 1. Among them:

[0100] The posture adjustment base plate 38 is used to carry the lithium battery PACK to be put into the cabinet.

[0101] The rotation mechanism 27 is used to drive the posture adjustment base plate 38 to rotate based on the drive of the electric actuator 51.

[0102] The pushing mechanism is used to push the lithium battery PACK from the posture adjustment base plate 38 into the energy storage cabinet based on the drive of the servo motor 52, or to pull out the lithium battery PACK in the energy storage cabinet.

[0103] In order to further enhance the bearing capacity of the posture adjustment base plate 38, a support frame 37 or a reinforcing rib can also be provided under the posture adjustment base plate 38.

[0104] In a non-limiting embodiment, a clamping mechanism 39 and / or a blocking mechanism 40 can be provided on the posture adjustment base plate 38. The clamping mechanism 39 is used to clamp the lithium battery PACK; the blocking mechanism 40 is used to block the lithium battery PACK from sliding out from the front of the posture adjustment base plate 38.

[0105] In specific implementation, the clamping mechanism 39 can be realized by using a clamping electric cylinder. For example, two clamping electric cylinders are arranged on both sides of the posture adjustment base plate 38 to realize the clamping and loosening of the lithium battery PACK. The blocking mechanism 40 can be realized by using a stop block, which is arranged in front of the posture adjustment base plate 38 and is opened before the lithium battery PACK enters the cabinet and closed after the lithium battery PACK enters the cabinet. After the lithium battery PACK is placed on the posture adjustment base plate 38, the clamping electric cylinders on both sides are clamped and self-locked. Cooperating with the stop block, the safety of the lithium battery PACK during handling can be ensured.

[0106] In a non-limiting embodiment, the carrier system may further include: a wheel frame mechanism for adapting to lithium battery PACKs of different widths.

[0107] The wheel frame mechanism is arranged above the posture adjustment base plate 38 and includes: a wheel frame 34, a guide plate 36, and a wheel frame support 341. Among them, the wheel frame support 341 and the guide plate 36 are detachably installed on the wheel frame 34; the wheel frame 34 is installed on the posture adjustment base plate 38. The wheel frame support 342 can be, for example, a roller or other support structures, and the embodiments of the present application do not limit this.

[0108] As Figure 5 shown, in some embodiments, there can be multiple wheel frame supports 341 (for example, 4 - 6 are arranged on each side), which are arranged on both sides of the posture adjustment base plate 38; a guide plate 36 is arranged on each wheel frame support 341. The guide plate 36 can better ensure the route of the lithium battery PACK entering the cabinet and prevent the lithium battery PACK from slipping off the side of the posture adjustment base plate 38 when the force is uneven.

[0109] In some embodiments, the installation position of the wheel frame support 341 is adjustable. For example, multiple different installation positions are reserved on the vehicle body 1, so that the width of the wheel frame 34 is adjustable, thereby conveniently adapting to lithium battery PACKs of different widths.

[0110] Furthermore, a buffer cushion plate 35 can be connected to each guide plate 36. The buffer cushion plate 35 can be made of a relatively soft material, such as plastic, silica gel, etc., to avoid scratching or knocking the lithium battery PACK when the lithium battery PACK is placed on the posture adjustment base plate 38.

[0111] Figure 8 Fig. shows a schematic structural diagram of the rotation mechanism in the embodiments of the present application.

[0112] At the same time, referring to Figure 3 、 Figure 5 and Figure 8, the rotation mechanism includes: a rotating base plate 271, a slewing bearing 272, and a mounting base plate 273. Among them, the mounting base plate 273 is fixedly installed on the carriage 22; the rotating base plate 271 is installed on the mounting base plate 273 through the slewing bearing 272. In addition, the rotating base plate 271 is also connected to the posture adjustment base plate 38.

[0113] The pushing mechanism includes: a slide plate 30, a guide rail slider 31, a track 32, and a push rod 301. Among them, the track 32 is provided on the slide plate 30; the guide rail slider 31 is installed on the track 32 and can slide along the track 32 under the drive of the servo motor 52; the push rod 301 is provided on both sides of the slide plate 30 and is connected to the slide plate 30 for pushing the lithium battery PACK package to be put into the cabinet on the posture adjustment base plate. For example, the servo motor 52 can drive the guide rail slider 31 and the slide plate 30 to move through the gear rack 33, so as to realize the pushing of the lithium battery PACK package. When pulling out the lithium battery PACK package, just connect the push rod 301 and the lithium battery PACK package with a steel wire rope with hooks at both ends, and it can be easily pulled out.

[0114] In specific implementation, the track 32 can be set as two parallel tracks, and there can be four guide rail sliders 31, with two arranged on each track, which can better maintain the balance state when the slide plate 30 moves.

[0115] In a non-limiting embodiment, the carrier system may further include: a thrust sensor 302, which is arranged on the pushing mechanism, for example, can be arranged at the rear end of the push rod 301 to feedback the thrust of the push rod 301 on the lithium battery PACK package to the control system 5.

[0116] Correspondingly, the control system 5 detects whether the thrust exceeds the set value, and when the thrust exceeds the set value, controls the pushing mechanism to stop operating and triggers an alarm.

[0117] In specific implementation, two independent thrust sensors can be respectively configured on the two push rods 34 to protect the mechanical jamming of the lithium battery PACK package during the process of being pushed into the cabinet. When the sensor data is abnormal, the control system 5 controls the servo motor 52 to stop working.

[0118] For the convenience of operation, the control system 5 can be encapsulated in a box body, and corresponding display panels and control buttons are arranged on the box body to realize the control of each system component.

[0119] Continue to refer to 3, Figure 6 and Figure 7, the traveling mechanism includes: drive wheels 13, load wheels 14, and balance wheels 15. The load wheels 14 are arranged on both sides of the front end of the bottom of the vehicle body 1, the balance wheels 15 are arranged on both sides of the rear end of the bottom of the vehicle body 1, and the drive wheels 13 are arranged between the two balance wheels 15. The steering of the drive wheels 13 can be controlled by the steering motor 131.

[0120] The drive system includes: a drive device 411, and a hydraulic device 412 and a steering motor 413 connected to the drive device 411.

[0121] In some embodiments, the lithium battery PACK cabinet stacker can be designed in a semi-automatic operation mode, that is, the walking of the vehicle and the operation of putting the lithium battery PACK into the cabinet are completed by manual control. Correspondingly, in this design, an operation handle 101 can be arranged on the drive system 4; a standing board 103 can also be arranged on the vehicle body 1 for the operator to stand on.

[0122] Furthermore, protective arms 102 can be arranged on both sides of the drive system to ensure the safety of the operator on the standing board 103 during the walking process of the lithium battery PACK cabinet stacker.

[0123] Furthermore, a key switch 11 and an emergency stop switch 12 can also be arranged on the drive device. The key switch 11 is used to turn on the power supply of the power-consuming units (such as the control system 5, the drive system 4, etc.) and enter the working state; the emergency stop switch 12 is used to cut off the power supply in case of an emergency and stop the lithium battery PACK cabinet stacker from working.

[0124] Furthermore, the drive system can also include a shock absorption device 414 (such as a buffer spring, etc.) to reduce the influence of the vibration caused by the ground during the travel of the lithium battery PACK cabinet stacker on the internal components and ensure the normal operation of each component.

[0125] Furthermore, as Figure 5 shown, the lithium battery PACK cabinet stacker can also include: a visual assistance device 41 for personnel to view and align the feature points of the container. The visual assistance device 41 can include, but is not limited to, any one or more of the following devices: a laser detector, a wireless camera, a display screen, etc., which can assist the operator to more clearly observe the operation of putting into the cabinet and facilitate adjusting the position of putting into the cabinet.

[0126] In some embodiments, the lithium battery PACK cabinet stacker can be designed in a full-automatic operation mode. For example, referring to Figure 5 and Figure 7, corresponding visual assistance devices 41, laser calibration devices 42, electronic steering devices 43, and remote control devices can be set. The visual assistance device 41 and the laser calibration device 42 are arranged on the vehicle body 1. Correspondingly, a receiving antenna, a signal analysis module, and corresponding software are arranged in the control system 5. Among them:

[0127] The remote control device is used to send a remote control instruction to the driving device 411, so that the driving device 411 drives the traveling mechanism to move through the electronic steering device 43;

[0128] The visual assistance device 41 is used to sense the surrounding environment of the vehicle body 1;

[0129] The laser calibration device 42 is used for personnel to view the left-right relative positions of the vehicle body and the container, and correct the moving route of the traveling mechanism, so as to realize the autonomous movement of the lithium battery PACK cabinet stacker.

[0130] Further, a power meter 10 can also be arranged on the driving device, so that the operator can timely understand the current power of the equipment.

[0131] Further, an indicator light 104 can also be arranged on the vehicle body 1 to indicate whether the lithium battery PACK cabinet stacker is in the working state currently.

[0132] The lithium battery PACK cabinet stacker provided by the embodiment of the present application can cooperate with a lifting device to complete the operation of loading the lithium battery PACK into the cabinet. The specific operation process is as follows:

[0133] 1. Transport the lithium battery PACK to the unpacking position by a forklift for unpacking operation;

[0134] 2. After the lithium battery is unpacked, hoist the lithium battery PACK to the buffer rack by a cantilever crane and fix it;

[0135] 3. The cabinet stacker travels to the hoisting station to prepare to load the lithium battery PACK;

[0136] 4. Manually push the lithium battery PACK onto the posture adjustment bottom plate of the carrier system of the cabinet stacker; then, lock the lithium battery PACK;

[0137] 5. The cabinet stacker runs along the specified route to the front of the energy storage cabinet;

[0138] 6. After the in-cab stacker reaches the cabinet platform, control the up and down movement of the carriage in the gantry system to adjust the height of the posture adjustment base plate in the carrier system so that its height is flush with the in-cab position. Then, control the rotation mechanism in the carrier system to drive the posture adjustment base plate to move back and forth, left and right, so that the lithium battery PACK is aligned with the bin opening of the energy storage cabinet. Then, release the clamping mechanism and the limiting mechanism, and control the pushing mechanism to push the lithium battery PACK into the target position in the bin.

[0139] After the lithium battery PACK is pushed into the target position in the bin, manually confirm and execute the loading.

[0140] Further, in some embodiments, the thrust sensor provided on the pushing mechanism when the lithium battery PACK is pushed can also feedback the thrust of the pushing mechanism on the lithium battery PACK to the control system. When it is detected that the thrust exceeds the set value (the set value can be set to different values according to different lithium battery PACKs), it is determined that there is a deviation in the in-cab operation or there is a risk of damaging the lithium battery PACK, and the control system controls the pushing mechanism to stop the in-cab operation and trigger an alarm.

[0141] 7. The in-cab stacker exits the loading position and returns to the hoisting station according to the running line, preparing to enter the next cycle.

[0142] The in-cab stacker for lithium battery PACK provided by the embodiments of the present application has a simple structure, low maintenance and repair costs, light weight, low height, and low energy consumption, and it is easy and fast to access the lithium battery PACK. Using this in-cab stacker for lithium battery PACK can greatly improve the in-cab operation efficiency of the lithium battery PACK.
