Description

Technical Field

[0001] The present application relates to the technical field of battery manufacturing, and in particular to a stacker. Background Art

[0002] New energy batteries are increasingly used in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are increasingly used in the field of energy storage. In new energy vehicles equipped with batteries, batteries can be used to provide power in whole or in part. In the field of energy storage, batteries can be installed in energy storage boxes or directly on the user side.

[0003] With the continuous development of battery technology, how to improve battery production efficiency is one of the topics that the industry needs to study. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a stacking machine that can improve the production efficiency of battery cells.

[0005] This application is implemented through the following technical solutions.

[0006] A first aspect of the present application provides a stacker, comprising: a cargo platform, the cargo platform being used to carry a pallet containing battery cells; and at least one exhaust mechanism installed on the cargo platform, the exhaust mechanism being configured to dock with the battery cells in the pallet carried on the cargo platform and perform an exhaust operation to discharge the gas in the battery cells to the outside.

[0007] When using the stacker provided in the embodiment of the present application to transfer battery cells, the tray containing the battery cells is placed on the loading platform, the exhaust mechanism is connected to the battery cells in the tray, and the gas in the battery cells is discharged to the outside. After the battery cells are exhausted by the exhaust mechanism, the electrolyte infiltration speed can be accelerated, thereby shortening the static time of the battery cells on the shelf. In addition, the exhaust operation of the battery cells by the exhaust mechanism is performed during the process of the stacker transferring the battery cells, which does not take up extra time, thereby shortening the production cycle of the battery cells. Moreover, after exhaust, the electrolyte in the battery cells is fully contacted with the active materials of the positive electrode sheet and the negative electrode sheet, thereby improving the battery capacity, charging and discharging efficiency and reducing the internal resistance. In addition, since the gas in the battery cells has been exhausted once, the amount of gas in the battery cells is less during the subsequent formation exhaust of the battery cells, so the time used for formation exhaust can be reduced, thereby further shortening the production cycle of the battery cells and further improving the production efficiency of the battery cells.

[0008] In some embodiments, the exhaust mechanism includes: an exhaust base connected to the cargo platform; a accommodating cavity installed on the exhaust base, the accommodating cavity having an inner cavity; an air suction component including a straw and a suction nozzle, the suction end of the straw is equipped with the suction nozzle, the discharge end of the straw is connected to the accommodating cavity and communicated with the inner cavity, the suction nozzle is configured to be able to connect with or separate from the exhaust valve body of the battery cell, and when the suction nozzle and the exhaust valve body are connected, the suction nozzle can absorb the gas in the battery cell; an exhaust component including an exhaust pipe and a first vacuum pump, the gas inlet end of the exhaust pipe is connected to the top of the accommodating cavity and communicated with the inner cavity, and the gas discharge end of the exhaust pipe is connected to the first vacuum pump.

[0009] In this way, the exhaust mechanism can discharge the gas in the battery cell. Moreover, the exhaust mechanism has a simple structure and low cost.

[0010] In some embodiments, the exhaust mechanism also includes a drainage assembly, which includes a drainage pipe and a second vacuum pump. The liquid inlet end of the drainage pipe is connected to the bottom of the accommodating cavity and communicates with the inner cavity, and the liquid outlet end of the drainage pipe is connected to the second vacuum pump.

[0011] In this way, the exhaust mechanism can discharge the liquid in the battery cell. Moreover, the exhaust mechanism has a simple structure and low cost.

[0012] In some embodiments, the exhaust mechanism includes at least two suction components spaced apart along the first direction, at least two suction components are connected to the same accommodating cavity, and the suction nozzle of each suction component can be docked with each battery cell in a one-to-one correspondence.

[0013] There are usually at least two battery cells arranged in the tray. By increasing the number of air intake components, multiple battery cells can be exhausted simultaneously, thereby improving exhaust efficiency. Moreover, at least two air intake components are connected to the same accommodating cavity, that is, the exhaust of at least two battery cells can share the accommodating cavity and the exhaust component, which simplifies the structure of the exhaust mechanism, reduces the number of components, and saves costs.

[0014] In some embodiments, at least two exhaust mechanisms are provided, and all the exhaust mechanisms are arranged in sequence along a second direction intersecting the first direction.

[0015] By increasing the number of exhaust mechanisms along the second direction, the suction nozzles of the exhaust mechanisms are arranged in a matrix, and the battery cells in the tray are usually also arranged in a matrix. In this way, the suction nozzles and the battery cells arranged in the matrix can be docked one-to-one to improve the exhaust efficiency.

[0016] In some embodiments, the cargo platform has a storage space, and the storage space has a loading position and an exhaust position. The stacker also includes at least one pushing mechanism, and the pushing mechanism is connected to the cargo platform. The pushing mechanism is configured to push the pallet located at the loading position to the exhaust position. The pushing mechanism pushes the pallet to the exhaust position so that the exhaust mechanism and the battery cell are docked.

[0017] In this way, the battery cells in the tray are connected to the exhaust mechanism by the pushing mechanism, so as to facilitate the subsequent exhaust operation. The docking operation is simple and fast, and the exhaust efficiency is high.

[0018] In some embodiments, the exhaust position is located above the carrying position, and the pushing mechanism is configured to abut against the bottom of the tray and lift the tray upward.

[0019] The exhaust position is located above the load-bearing position, and the pushing mechanism pushes the pallet to move by lifting it from bottom to top, so that the exhaust valve body of the battery cell can accurately dock with the suction nozzle. It can also reduce the space occupied in the horizontal direction and reduce the horizontal size of the cargo platform.

[0020] In some embodiments, the pushing mechanism includes a lifting drive and a lifting member, the lifting drive is connected to the cargo platform, the lifting member is connected to the output end of the lifting drive, and the lifting drive is used to drive the lifting member to rise and fall so that the lifting member contacts and lifts the pallet to the exhaust position.

[0021] In this way, the function of the pushing mechanism to lift the tray is realized. Moreover, the pushing mechanism has a simple structure and low cost.

[0022] In some embodiments, the lifting member includes a support plate and a limit plate connected to the support plate, the support plate is connected to the output end of the lifting drive member and supported on the bottom of the tray, and the limit plate is blocked on the outer peripheral side of the tray.

[0023] In this way, the tray can be pushed upward and the movable position of the tray on its peripheral side can be limited, which is conducive to improving the accuracy of the moving path of the tray during the rising process, thereby improving the success rate of the docking between the battery cell and the suction nozzle.

[0024] In some embodiments, the cargo platform includes: a base frame, the base frame having the accommodating space, and a material picking position outside the accommodating space; a material picking carrying plate, the material picking carrying plate is configured to be able to reciprocate between the material picking position and the carrying position, and the material picking carrying plate is used to receive the pallet when located at the material picking position.

[0025] In this way, after the material-retrieving carrying plate extends from the accommodating space to the material-retrieving position, it can be conveniently received by the pallet, thereby improving the smoothness of the pallet transfer.

[0026] In some embodiments, a through opening is provided at the bottom of the cargo platform, the pushing mechanism is connected to the bottom of the cargo platform, and the pushing end of the pushing mechanism can enter the accommodating space through the through opening to contact and lift the pallet.

[0027] Since the pushing mechanism is connected to the bottom of the cargo platform and does not occupy the storage space of the cargo platform, the size of the cargo platform is smaller, thereby reducing the space occupied by the cargo platform.

[0028] In some embodiments, the stacker also includes a fire extinguishing system, which is connected to the cargo platform and located above the exhaust mechanism. The fire extinguishing system is configured to detect smoke and temperature, and perform a fire extinguishing operation by spraying a fire extinguishing medium when the detection results meet preset conditions.

[0029] When the test results reach the preset conditions, it indicates that an abnormal reaction has occurred inside the battery cell and that the abnormal temperature rise of the battery cell has caused a fire. By spraying the fire extinguishing medium through the fire extinguishing system, the fire can be controlled as soon as possible, thereby improving the safety factor of the exhaust operation.

[0030] In some embodiments, the fire extinguishing system includes: a spraying assembly connected to the cargo platform, the spraying assembly being used to spray the fire extinguishing medium; a detection component connected to the spraying assembly and being used to detect smoke and temperature; a main inlet pipe group, whose inlet end is used to connect to a pipe supplying the fire extinguishing medium, and whose outlet end is connected to the spraying assembly; a first stop valve installed on the main inlet pipe group, being used to open or disconnect the main inlet pipe group; when the detection result of the detection component reaches the preset condition, the first stop valve is opened, thereby opening the main inlet pipe group, so that the fire extinguishing medium is introduced into the spraying assembly through the main inlet pipe group to perform the fire extinguishing operation.

[0031] In this way, the fire extinguishing system can detect fire and extinguish fire, and the safety factor of exhaust operation is improved. Moreover, the fire extinguishing system has a simple structure and low cost.

[0032] In some embodiments, the fire extinguishing system further includes: a spare inlet pipe group, whose inlet end is used to connect to a pipe supplying the fire extinguishing medium and whose outlet end is connected to the spray assembly; a second stop valve installed on the spare inlet pipe group, used to open or disconnect the spare inlet pipe group; when the detection result of the detection component reaches the preset condition and the main inlet pipe group fails to work, the second stop valve opens, thereby opening the spare inlet pipe group, so that the fire extinguishing medium is introduced into the spray assembly through the spare inlet pipe group to perform the fire extinguishing operation.

[0033] In this way, when the main inlet pipe group cannot work normally due to damage or other reasons, the spare inlet pipe group and the second stop valve can be activated, further improving the installation coefficient of the exhaust operation.

[0034] In some embodiments, the cargo platform is equipped with a protective plate, and the protective plate blocks the top of the fire extinguishing system.

[0035] In this way, the protection effect of the fire extinguishing system is improved.

[0036] In some embodiments, the stacker further includes a frame and a lifting mechanism, the cargo platform and the lifting mechanism are respectively arranged on the frame, and the lifting mechanism is configured to be able to drive the cargo platform to rise and fall.

[0037] In this way, the lifting and lowering of the cargo platform is realized through the setting of the lifting mechanism, and the stacker can take away the pallet from different position heights or transport the pallet to different position heights, thereby realizing the stacking function of the stacker.

[0063] Below, this application is described in detail.

[0064] At present, new energy batteries are increasingly used in life and industry. New energy batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0065] In the embodiment of the present application, the battery may be a battery cell.

[0066] After the battery cells (sometimes also called cells) are filled, they are placed on the shelf in a tray and kept in a high temperature and dry environment. During the resting process, the electrolyte will gradually penetrate into the electrode assembly and fully penetrate between the positive and negative electrode materials to establish a good ion conduction channel, thereby improving the capacity and performance stability of the battery cells.

[0067] At present, battery cells need to be left standing for a relatively long time to ensure that the electrolyte fully penetrates between the positive and negative electrode materials. Long standing time will extend the production cycle of the entire battery cell and affect the production efficiency of the battery cell.

[0068] After research, the inventors of the present application discovered that adding an exhaust mechanism to a stacker used to transfer battery cells and exhausting the battery cells through the exhaust mechanism can facilitate full contact between the electrolyte and the active materials of the positive and negative electrode plates, and can accelerate the infiltration speed of the electrolyte, thereby shortening the standing time of the battery cells on the shelves, thereby shortening the production cycle of the battery cells.

[0069] Based on such a design concept, the inventor of the present application designed a stacker, including a loading platform and an exhaust mechanism. The loading platform is used to carry a pallet containing battery cells, and the exhaust mechanism is installed on the loading platform. The exhaust mechanism is configured to dock with the battery cells in the pallet carried on the loading platform, and perform an exhaust operation to discharge the gas in the battery cells to the outside.

[0070] When the stacker is used to transfer battery cells, the pallet containing the battery cells is placed on the loading platform, and the exhaust mechanism docks the battery cells in the pallet and discharges the gas in the battery cells to the outside. In this way, the production cycle of the battery cells will not be extended due to the exhaust operation, and the electrolyte infiltration speed of the battery cells after exhaust by the exhaust mechanism can be accelerated, so the static time of the battery cells on the shelf can be shortened, thereby shortening the production cycle of the battery cells. Moreover, after exhaust, the electrolyte in the battery cells is fully contacted with the active materials of the positive and negative pole pieces, thereby improving the battery capacity, charging and discharging efficiency and reducing the internal resistance. In addition, since the gas in the battery cells has been exhausted once, the amount of gas in the battery cells is less during the subsequent formation and exhaust of the battery cells, so the time used for formation and exhaust can be reduced, thereby further shortening the production cycle of the battery cells and further improving the production efficiency of the battery cells.

[0071] The stacker provided in the embodiment of the present application can transfer battery cells during the battery cell production process, for example, it can be used to transfer battery cells after they have been placed on a shelf. Of course, those skilled in the art should understand that the stacker provided in the embodiment of the present application is not only used to transfer battery cells after they have been placed on a shelf, but can also be used to transfer battery cells between other adjacent production equipment during the battery cell production process.

[0072] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0073] The battery cell can be a lithium ion battery, a sodium ion battery, a sodium lithium ion battery, a lithium metal battery, a sodium metal battery, a lithium sulfur battery, a magnesium ion battery, a nickel hydrogen battery, a nickel cadmium battery, a lead storage battery, etc., which is not limited in the embodiments of the present application.

[0075] like Figure 1 and Figure 2 As shown, the battery cell 100 includes a shell, an electrode assembly 104 and a pole 106 . The shell has a receiving cavity. The pole 106 is installed in the shell. The electrode assembly 104 has a pole ear 105 . The electrode assembly 104 is received in the receiving cavity, and the pole ear 105 is connected to the pole 106 .

[0076] The electrode assembly 104 is a component in the battery cell 100 where an electrochemical reaction occurs. One or more electrode assemblies 104 may be included in the housing. The electrode assembly 104 is mainly formed by winding or stacking the positive electrode sheet and the negative electrode sheet, and a separator is usually provided between the positive electrode sheet and the negative electrode sheet. The parts of the positive electrode sheet and the negative electrode sheet with active materials constitute the main body of the electrode assembly, and the parts of the positive electrode sheet and the negative electrode sheet without active materials each constitute the tab 105. The positive tab and the negative tab may be located together at one end of the main body or respectively at both ends of the main body. During the charge and discharge process of the battery, the positive active material and the negative active material react with the electrolyte, and the tab 105 connects the pole 106 to form a current loop.

[0077] The housing includes an end cap 102 and a shell 103 . The shell 103 has an opening. The end cap 102 closes the opening of the shell 103 to form a receiving cavity. The pole 106 is installed on the end cap 102 . The receiving cavity is used to receive the electrode assembly 104 , electrolyte and other components.

[0078] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a soft-pack battery cell or a battery cell of other shapes. The prismatic battery cell includes a square shell battery cell, a blade-shaped battery cell, a polygonal battery, such as a hexagonal battery, etc. There is no special limitation in this application.

[0079] In some embodiments, an exhaust valve body 101 is installed on the end cover 102, and the exhaust valve body 101 is used to exhaust the gas in the accommodating cavity of the shell.

[0080] The exhaust valve body 101 is used to exhaust the gas in the accommodating chamber. Therefore, the exhaust valve body 101 can be opened during exhaust, and after exhausting the gas, the exhaust valve body 101 is closed to form an internal environment isolated from the outside, thereby reducing the probability of leakage caused by the exhaust operation.

[0081] In some embodiments, the tray 200 includes a bottom plate 201 and four side plates 202 respectively arranged around the bottom plate 201 . The bottom plate 201 and the four side plates 202 define a receiving space for receiving the battery cells 100 . The receiving space is used to receive a plurality of battery cells 100 .

[0082] Below, refer to Figures 4 to 11 Some embodiments of the present application are described in detail.

[0084] In some embodiments of the present application, for the convenience of explanation, a first direction, a second direction, and a third direction are set, and the first direction, the second direction, and the third direction are directions that intersect each other. Here, intersecting each other includes intersecting each other perpendicularly. Figures 4 to 11 In the illustrated embodiment, the first direction, the second direction, and the third direction are perpendicular to each other for illustration, but those skilled in the art should understand that the embodiments of the present application are not limited to the case where the three directions are perpendicular to each other. Figures 4 to 10 As shown by the arrows in the figure, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the third direction. Sometimes the direction indicated by arrow Z along the third direction is called "upward", and the opposite direction is called "downward".

[0085] The present application embodiment provides a stacker, such as Figure 4 and Figure 5 As shown, the stacker includes a cargo platform 1 and at least one exhaust mechanism 2, the cargo platform 1 is used to carry a pallet 200 containing battery cells 100; at least one exhaust mechanism 2 is installed on the cargo platform 1, and the exhaust mechanism 2 is configured to dock with the battery cells 100 in the pallet 200 carried on the cargo platform 1, and perform an exhaust operation to discharge the gas in the battery cells 100 to the outside.

[0086] When using the stacker provided in the embodiment of the present application to transfer the battery cell 100, the tray 200 containing the battery cell 100 is placed on the cargo platform 1, and the exhaust mechanism 2 is connected to the battery cell 100 in the tray 200, and the gas in the battery cell 100 is discharged to the outside. After the battery cell 100 is exhausted by the exhaust mechanism 2, the electrolyte infiltration speed can be accelerated, thereby shortening the static time of the battery cell 100 on the shelf. In addition, the exhaust operation of the battery cell 100 by the exhaust mechanism 2 is performed during the process of the stacker transferring the battery cell 100, which does not take up extra time, thereby shortening the production cycle of the battery cell 100. Moreover, after exhaust, the electrolyte in the battery cell 100 is fully contacted with the active materials of the positive electrode sheet and the negative electrode sheet, thereby improving the battery capacity, charging and discharging efficiency and reducing the internal resistance. In addition, since the gas in the battery cell 100 has been discharged once, the amount of gas in the battery cell 100 is less during the subsequent formation and exhaust of the battery cell 100, so the time used for formation and exhaust can be reduced, thereby further shortening the production cycle of the battery cell 100 and further improving the production efficiency of the battery cell 100.

[0087] In some embodiments of the present application, Figure 7 and Figure 8As shown, the exhaust mechanism 2 includes an exhaust base 21, a accommodating cavity 22, an air suction component 23 and an exhaust component, the exhaust base 21 is connected to the cargo platform 1; the accommodating cavity 22 is installed on the exhaust base 21, and the accommodating cavity 22 has an inner cavity; the air suction component 23 includes a suction pipe 231 and a suction nozzle 232, the suction end of the suction pipe 231 is installed with a suction nozzle 232, the discharge end of the suction pipe 231 is connected to the accommodating cavity 22 and communicated with the inner cavity, the suction nozzle 232 is configured to be able to connect with or separate from the exhaust valve body 101 of the battery cell 100, and when the suction nozzle 232 and the exhaust valve body 101 are connected, the suction nozzle 232 can absorb the gas in the battery cell 100; the exhaust component includes an exhaust pipe 241 and a first vacuum pump (not shown in the figure), the gas inlet end of the exhaust pipe 241 is connected to the top of the accommodating cavity 22 and communicated with the inner cavity, and the gas discharge end of the exhaust pipe 241 is connected to the first vacuum pump.

[0088] After placing the pallet 200 on the cargo platform 1, the suction nozzle 232 and the exhaust valve body 101 of the battery cell 100 are connected to each other, so that the suction nozzle 232 and the storage cavity inside the battery cell 100 are connected. Then, the first vacuum pump is started. Under the suction action of the first vacuum pump, a negative pressure is formed in the inner cavity of the storage cavity 22, thereby forming a suction force at the suction nozzle 232. The suction nozzle 232 sucks out the gas in the battery cell 100, and enters the storage cavity 22 through the suction nozzle 232 and the suction pipe 231 in turn. After that, the gas in the storage cavity 22 is discharged through the exhaust pipe 241.

[0089] The suction nozzle 232 is a structure that can be connected to the exhaust valve body 101 of the battery cell 100 and has a flow channel. After the suction nozzle 232 and the exhaust valve body 101 of the battery cell 100 are connected, the suction nozzle 232 and the accommodating cavity of the battery cell 100 are connected, so that the gas in the battery cell 100 can enter the flow channel of the suction nozzle 232. After the exhaust operation is completed, the suction nozzle 232 can be separated from the exhaust valve body 101 to facilitate the transfer of the next batch of battery cells 100. The specific structure of the suction nozzle 232 is compatible with the structure of the exhaust valve body 101 and is not specifically limited here.

[0090] The exhaust valve body 101 is a structure having a guide channel, the guide channel is connected when it is connected to the suction nozzle 232, and the guide channel can be self-closed after being separated from the suction nozzle 232. Specifically, the suction nozzle 232 and the exhaust valve body 101 are connected, and after the two are connected, the suction nozzle 232 and the exhaust valve body 101 are connected, so that the gas in the battery cell 100 can enter the flow channel of the suction nozzle 232 through the exhaust valve body 101, so as to exhaust. After the exhaust is completed, the suction nozzle 232 and the exhaust valve body 101 are separated. After separation, the exhaust valve body 101 is self-closed, so that the accommodating cavity of the battery cell 100 is isolated from the external environment, and the probability of leakage caused by the exhaust operation is reduced. Exemplarily, the connector of the exhaust valve body 101 is made of silicone material, and an opening is provided on the connector. The opening is in a closed state when it is not connected to the suction nozzle 232. The suction nozzle 232 can be inserted into the opening to open the opening, forming a state in which the suction nozzle 232 and the exhaust valve body 101 are connected.

[0091] Exemplarily, one end of the exhaust pipe 241 away from the accommodating cavity 22 is connected to a three-way valve, two interfaces of the three-way valve are respectively connected to the exhaust pipe 241 and the gas outlet pipe, and the other interface is connected to the first vacuum pump, and the end of the gas outlet pipe away from the three-way valve is connected to the gas collection container.

[0092] In this way, the exhaust mechanism 2 realizes the function of exhausting the gas in the battery cell 100. Moreover, the exhaust mechanism 2 has a simple structure and low cost.

[0093] In some embodiments of the present application, the exhaust mechanism 2 also includes a drainage component, which includes a drainage pipe 251 and a second vacuum pump. The liquid inlet end of the drainage pipe 251 is connected to the bottom of the accommodating cavity 22 and communicates with the inner cavity, and the liquid discharge end of the drainage pipe 251 is connected to the second vacuum pump.

[0094] The storage cavity of the battery cell 100 also contains gases formed by the vaporization of the electrolyte and water vapor, etc. During the exhaust process, these gases will enter the storage cavity 22 through the air intake component 23. Due to factors such as the temperature difference between the battery cell 100 and the storage cavity 22, these gases will liquefy to form liquid in the storage cavity 22. The discharge component is used to discharge the liquid in the storage cavity 22.

[0095] The second vacuum pump is started. Under the suction action of the second vacuum pump, a suction force is formed at the liquid entrance end of the drain pipe 251. Since the liquid entrance end of the drain pipe 251 is connected to the bottom of the accommodating cavity 22 and the liquid is located at the bottom of the inner cavity of the accommodating cavity 22, the liquid can flow smoothly into the drain pipe 251 and be discharged outward through the drain pipe 251.

[0096] Exemplarily, one end of the drain pipe 251 away from the accommodating cavity 22 is connected to a three-way valve, two interfaces of the three-way valve are respectively connected to the drain pipe 251 and the liquid outlet pipe, and the other interface is connected to the second vacuum pump, and the end of the liquid outlet pipe away from the three-way valve is connected to the liquid collection container.

[0097] In this way, the exhaust mechanism 2 realizes the function of exhausting the liquid in the battery cell 100. Moreover, the exhaust mechanism 2 has a simple structure and low cost.

[0098] In some embodiments of the present application, the exhaust mechanism 2 includes at least two air intake components 23 spaced apart along the first direction X, at least two air intake components 23 are connected to the same accommodating cavity 22, and the suction nozzle 232 of each air intake component 23 can be docked with each battery cell 100 in a one-to-one correspondence.

[0099] There are usually at least two battery cells 100 arranged in the tray 200. By increasing the number of air intake assemblies 23, multiple battery cells 100 can be exhausted simultaneously, thereby improving exhaust efficiency. Moreover, at least two air intake assemblies 23 are connected to the same accommodating cavity 22, that is, the exhaust of at least two battery cells 100 can share the accommodating cavity 22 and the exhaust assembly, which simplifies the structure of the exhaust mechanism 2, reduces the number of components, and saves costs.

[0100] In some embodiments of the present application, Figure 8 As shown, the exhaust mechanism 2 includes at least two accommodating cavities 22 distributed in sequence in a first direction X, all accommodating cavities 22 in the same exhaust mechanism 2 are installed on the same exhaust base 21, each accommodating cavity 22 is connected to at least two suction components 23 spaced apart in the first direction X, and each accommodating cavity 22 is correspondingly connected to an exhaust pipe 241.

[0101] In this way, in the case of a tray 200 of the same specification, the accommodating cavity 22 of the exhaust mechanism 2 can be set to be relatively small, which is convenient for manufacturing and assembly.

[0102] In some embodiments of the present application, Figure 8 As shown, all exhaust pipes 241 of the same exhaust mechanism 2 are connected to the same exhaust main pipe 243 through a first collecting joint 242, and the exhaust main pipe 243 is connected to a first vacuum pump; all drain pipes 251 of the same exhaust mechanism 2 are connected to the same drain main pipe 253 through a second collecting joint 252, and the drain main pipe 253 is connected to a second vacuum pump.

[0103] In this way, the exhaust mechanism 2 uses a first vacuum pump and a second vacuum pump, and the number of vacuum pumps used is small, which saves costs.

[0104] In some embodiments of the present application, Figure 8As shown, the first aggregation joint 242 is fixedly connected to the exhaust base 21 through the fixed connector 26. In this way, the position of the exhaust pipe 241 is fixed, and the probability of the exhaust pipe 241 interfering with other parts during disassembly and assembly is reduced.

[0105] In some embodiments of the present application, at least two exhaust mechanisms 2 are provided, and all the exhaust mechanisms 2 are arranged in sequence along a second direction Y intersecting the first direction X.

[0106] By increasing the number of exhaust mechanisms 2 along the second direction Y, the suction nozzles 232 of the exhaust mechanisms 2 are arranged in a matrix, and the battery cells 100 in the tray 200 are also usually arranged in a matrix. In this way, the suction nozzles 232 and the battery cells 100 arranged in the matrix can be docked one-to-one to improve the exhaust efficiency.

[0107] In some embodiments of the present application, the first direction X and the second direction Y are perpendicular to each other.

[0108] In this way, it is suitable for performing exhaust operation on the battery cells 100 arranged in two perpendicular directions.

[0109] In some embodiments of the present application, the exhaust base 21 includes a top plate 211, a bottom plate 212 and a vertical plate 213, the two ends of the vertical plate 213 are respectively fixedly connected to the top plate 211 and the bottom plate 212, and two support rods 214 are connected between the top plate 211 and the bottom plate 212, and the two support rods 214 are both arranged at the same end of the top plate 211 and the bottom plate 212 along the first direction X, and the fixed connector 26 is fixed to the end of the top plate 211, and the exhaust pipe 241 and the drain pipe 251 pass through the gap between the two support rods 214. The accommodating cavity 22 is fixed to the lower side of the top plate 211 through the cavity fixing plate 215, and the bottom plate 212 is connected to the side cover plate 216, and the suction nozzle 232 is clamped between the side cover plate 216 and the bottom plate 212.

[0110] In this way, the exhaust base 21 has a simple structure and low cost, and can limit the positions of the exhaust pipe 241 and the drain pipe 251, thereby improving the compactness of the structure.

[0111] Exemplarily, the suction tube 231 is fixed to the air outlet of the suction nozzle 232 by means of a buckle 217. The gas inlet end of the exhaust pipe 241 is connected to the top of the accommodating cavity 22 by means of an L-shaped exhaust joint 218, and the drain pipe 251 is connected to the bottom of the accommodating cavity 22 by means of an L-shaped drain pipe joint 219. In this way, the exhaust pipe 241 and the drain pipe 251 are substantially extended along the first direction X, so that the exhaust pipe 241 and the drain pipe 251 are arranged in a relatively regular manner, reducing the probability of interference with the installation of other components, and also facilitating the gas and liquid to be led outwardly of the exhaust base 21 along the first direction X.

[0112] In some embodiments of the present application, the cargo platform 1 has a accommodating space, and the accommodating space has a loading position and an exhaust position. The stacker also includes at least one pushing mechanism 3, which is connected to the cargo platform 1. The pushing mechanism 3 is configured to push the pallet 200 located at the loading position to the exhaust position. The pushing mechanism 3 pushes the pallet 200 to the exhaust position so that the exhaust mechanism 2 and the battery cell 100 are docked.

[0113] The pushing mechanism 3 can push the tray 200 in the vertical direction or in a direction forming an acute angle with the vertical direction. The specific pushing direction is determined by the orientation of the connector of the exhaust valve body 101 of the battery cell 100 .

[0114] In this way, the battery cells 100 in the tray 200 are connected to the exhaust mechanism 2 by the pushing mechanism 3 to push the tray 200, so as to facilitate the subsequent exhaust operation. The docking operation is simple and fast, so that the exhaust efficiency is high.

[0115] In some embodiments of the present application, the exhaust position is located above the carrying position, and the pushing mechanism 3 is configured to abut against the outer bottom surface of the tray 200 and lift the tray 200 upward.

[0116] Exemplarily, the pushing mechanism 3 is configured to push the tray 200 along a third direction Z perpendicular to both the first direction X and the second direction Y. When the tray 200 is placed, the first direction X and the second direction Y are approximately in a horizontal plane, and therefore, the third direction Z is approximately in a vertical direction.

[0117] The exhaust position is located above the load-bearing position, and the pushing mechanism 3 pushes the tray 200 to move by lifting it from bottom to top, so that the exhaust valve body 101 of the battery cell 100 can be accurately docked with the suction nozzle 232. Moreover, it can also reduce the space occupied in the horizontal direction and reduce the horizontal size of the cargo platform 1.

[0118] In some embodiments of the present application, Fig. 9 As shown, the pushing mechanism 3 includes a lifting drive member 31 and a lifting member 32. The lifting drive member 31 is connected to the cargo platform 1, and the lifting member 32 is connected to the output end of the lifting drive member 31. The lifting drive member 31 is used to drive the lifting member 32 to rise and fall so that the lifting member 32 contacts and lifts the pallet 200 to the exhaust position.

[0119] When exhaust is required, the lifting member 31 drives the lifting member 32 to rise, and the lifting member 32 pushes against the outer bottom surface of the tray 200 to lift up, so that the tray 200 rises. When it rises to the exhaust position, the lifting member 31 stops driving. At this time, the suction nozzle 232 of the exhaust mechanism 2 is connected to the exhaust valve body 101 of the battery cell 100 in a one-to-one correspondence. After the exhaust is completed, the lifting member 31 drives the lifting member 32 to descend, and the tray 200 descends synchronously with the lifting member 32 under the action of gravity, so as to reset to the carrying position, so that the exhausted battery cells 100 can be removed from the stacker through the tray 200.

[0120] In this way, the function of the pushing mechanism 3 to lift the tray 200 is realized. Moreover, the pushing mechanism 3 has a simple structure and low cost.

[0121] In some embodiments of the present application, Fig. 9 As shown, at least two pushing mechanisms 3 are provided, which are used to push against two opposite edges of the bottom of the tray 200 respectively.

[0122] In this way, the size of the lifting member 32 can be set relatively small, reducing costs and occupying less space. The pushing mechanism 3 pushes against two opposite edges of the bottom of the tray 200 respectively, which can improve the stability of the pushing.

[0123] Exemplarily, four pushing mechanisms 3 are provided, two of which are used to push against one long edge of the bottom of the tray 200 , and the other two are used to push against the other long edge of the bottom of the tray 200 .

[0124] In some embodiments of the present application, see Fig. 9 The lifting member 32 includes a support plate 321 and a limit plate 322 connected to the support plate 321 . The support plate 321 is connected to the output end of the lifting driving member 31 and supported on the bottom of the tray 200 . The limit plate 322 is blocked on the outer peripheral side of the tray 200 .

[0125] In this way, the tray 200 can be pushed upward and the movable position of the tray 200 on its peripheral side can be limited, which is beneficial to improve the accuracy of the moving path of the tray 200 during the rising process, thereby improving the success rate of the docking between the battery cell 100 and the suction nozzle 232.

[0126] In some embodiments of the present application, Fig. 9 As shown, a first guide mounting frame 34 is installed on the cargo platform 1, and a guide block 33 is installed on the first guide mounting frame 34. Guide blocks 33 are arranged on opposite sides of the exhaust position, and the surface of each guide block 33 facing the exhaust position includes a first guide slope 331. Along the direction from the load-bearing position to the exhaust position, the first guide slope 331 is inclined toward the direction close to another first guide slope 331 opposite to it.

[0127] In this way, when the tray 200 moves from the carrying position to the exhaust position, the first guide slope 331 guides and corrects the tray 200, thereby further improving the accuracy of the moving path of the tray 200 and further improving the success rate of docking between the battery cell 100 and the suction nozzle 232.

[0128] In some embodiments of the present application, Figure 6 As shown, the cargo platform 1 includes a base frame 11 and a material picking supporting plate 12. The base frame 11 has a accommodating space, and a material picking position outside the accommodating space; the material picking supporting plate 12 is configured to be able to reciprocate between the material picking position and the carrying position. The material picking supporting plate 12 is used to receive the pallet 200 when it is located at the material picking position.

[0129] The material picking supporting plate 12 is used to receive the tray 200 when it extends from the accommodating space to the material picking position. After receiving the tray 200, the material picking supporting plate 12 retracts from the material picking position to the carrying position. Thereafter, the tray 200 located at the carrying position is pushed to the exhaust position by the pushing mechanism 3. At this time, the exhaust mechanism 2 and the battery cell 100 are connected to each other, the exhaust mechanism 2 is started, and the exhaust operation begins.

[0130] When the material picking supporting plate 12 is extended from the accommodating space to the material picking position, it can directly extend to the bottom of the tray 200 for fork picking, or the tray 200 can be placed on the material picking supporting plate 12 at the material picking position through other transfer devices.

[0131] In this way, after the material-retrieving carrying plate 12 is extended from the accommodating space to the material-retrieving position, the tray 200 can be conveniently received, thereby improving the smoothness of the transfer of the tray 200 .

[0132] Exemplarily, a material-collecting driving member (not shown in the figure) is installed on the cargo platform 1, and the material-collecting carrying plate 12 is connected to the output end of the material-collecting driving member, and the material-collecting driving member is used to drive the material-collecting carrying plate 12 to reciprocate between the material-collecting position and the carrying position along the first direction X. Optionally, the material-collecting carrying plate 12 is slidably connected to the cargo platform 1 along the first direction X through a guide rail and a slider, thereby improving the smoothness of the movement of the material-collecting carrying plate 12.

[0133] In some embodiments of the present application, Figures 4 to 6 As shown, the cargo platform 1 has two accommodating spaces distributed in the second direction Y, and the movements of the material-retrieving carrying plates 12 in the two accommodating spaces are performed independently of each other, thereby improving the efficiency of transferring the battery cells 100 .

[0134] In some embodiments of the present application, Figures 4 to 6As shown, two material-taking bearing plates 12 are arranged in each accommodation space, and the two material-taking bearing plates 12 in the same accommodation space move synchronously to carry the same tray 200. In this way, the stability of carrying the tray 200 can be improved.

[0135] In some embodiments of the present application, a through opening is provided at the bottom of the cargo platform 1 , and the pushing mechanism 3 is connected to the bottom of the cargo platform 1 . The pushing end of the pushing mechanism 3 can enter the accommodating space through the through opening to contact and lift the pallet 200 .

[0136] Exemplarily, a through opening is provided at the bottom of the base 11, and the lifting drive member 31 of the pushing mechanism 3 is installed at the bottom of the base 11, and the lifting member 32 is connected to the output end of the lifting drive member 31. When not lifting, the lifting member 32 is located near the through opening and does not contact the tray 200. When lifting, the lifting drive member 31 drives the lifting member 32 to rise, and the lifting member 32 extends into the accommodating space through the through opening, thereby contacting and lifting the tray 200.

[0137] Since the pushing mechanism 3 is connected to the bottom of the cargo platform 1 and does not occupy the storage space of the cargo platform 1 , the size of the cargo platform 1 is smaller, thereby reducing the space occupied by the cargo platform 1 .

[0138] In some embodiments of the present application, Fig. 9 As shown, a second guide mounting frame 13 is installed on the cargo platform 1, and a guide bar 14 is installed on the second guide mounting frame 13. Guide bars 14 are arranged on opposite sides of the load-bearing position, and the surface of each guide bar 14 facing the load-bearing position includes a second guide slope 141. Along the direction from the material picking position to the load-bearing position, the second guide slope 141 is inclined toward the direction close to another second guide slope 141 opposite to it.

[0139] In this way, when the tray 200 moves from the material picking position to the carrying position, the second guide slope 141 guides and corrects the tray 200, thereby further improving the accuracy of the moving path of the tray 200, thereby further improving the success rate of docking between the battery cell 100 and the suction nozzle 232.

[0140] In some embodiments of the present application, the stacker also includes a fire extinguishing system 4, which is connected to the cargo platform 1 and located above the exhaust mechanism 2. The fire extinguishing system 4 is configured to detect smoke and temperature, and perform a fire extinguishing operation by spraying a fire extinguishing medium when the detection results meet preset conditions.

[0141] The fire extinguishing medium can be but is not limited to water, dry powder, carbon dioxide or inert gas (such as helium, argon, nitrogen, etc.). When the detection result reaches the preset condition, the fire extinguishing system 4 sprays the fire extinguishing medium, and the fire extinguishing medium falls onto the exhaust mechanism 2 and the tray 200, which can extinguish the fire on a large scale.

[0142] The preset conditions include at least one of the smoke concentration and temperature reaching their respective abnormal standards. When the detection result reaches the preset conditions, it indicates that an abnormal reaction has occurred inside the battery cell 100, and the abnormal temperature rise of the battery cell 100 has caused a fire. If it is not controlled in time, it is easy to cause a larger fire or explosion. For this reason, the present application provides a fire extinguishing system 4, which sprays a fire extinguishing medium through the fire extinguishing system 4, so that the fire can be controlled as soon as possible, thereby improving the safety factor of the exhaust operation.

[0143] In some embodiments of the present application, Fig.10 As shown, the fire extinguishing system 4 includes a spraying assembly 41, a detection component 42, a main inlet pipe group 43 and a first stop valve 44. The spraying assembly 41 is connected to the cargo platform 1, and the spraying assembly 41 is used to spray the fire extinguishing medium; the detection component 42 is connected to the spraying assembly 41, and is used to detect smoke and temperature; the inlet end of the main inlet pipe group 43 is used to connect the pipeline for supplying the fire extinguishing medium, and the outlet end is connected to the spraying assembly 41; the first stop valve 44 is installed on the main inlet pipe group 43, and is used to connect or disconnect the main inlet pipe group 43; when the detection result of the detection component 42 reaches the preset condition, the first stop valve 44 is opened, thereby connecting the main inlet pipe group 43, so that the fire extinguishing medium is introduced into the spraying assembly 41 through the main inlet pipe group 43 to perform a fire extinguishing operation.

[0144] Exemplarily, the spray assembly 41 includes a spray pipeline and a nozzle 411 installed on the spray pipeline. The spray pipeline is connected to the main inlet pipe group 43. After the main inlet pipe group 43 inputs the fire extinguishing medium into the spray pipeline, the fire extinguishing medium flows through the nozzle 411 and is sprayed outward.

[0145] For example, the detection element 42 may be, but is not limited to, a temperature and smoke sensor. The first stop valve 44 may be, but is not limited to, an electromagnetic stop valve.

[0146] In this way, the fire extinguishing system 4 can detect fire and extinguish fire, and the safety factor of exhaust operation is improved. Moreover, the fire extinguishing system 4 has a simple structure and low cost.

[0147] In some embodiments of the present application, Fig.10As shown, two spray assemblies 41 are provided along the second direction Y, and the inlet ends of the two spray assemblies 41 are respectively connected to the same main inlet pipe group 43. The main inlet pipe group 43 is provided with a first stop valve 44 corresponding to the two spray assemblies 41, and the two first stop valves 44 respectively control whether the fire extinguishing medium enters the two spray assemblies 41. In this way, when a fire occurs in a certain area, only the first stop valve 44 controlling the spray assembly 41 in the area can be opened, and the other spray assembly 41 can be stopped, which plays a role in saving materials. In addition, if both areas are on fire, the two first stop valves 44 are opened, which increases the range of the fire extinguishing medium spraying, thereby accelerating the efficiency of fire extinguishing.

[0148] In some embodiments of the present application, Fig.10 The fire extinguishing system 4 further includes a spare inlet pipe group 45 and a second stop valve 46. The inlet end of the spare inlet pipe group 45 is used to connect to a pipeline for supplying fire extinguishing medium, and the outlet end is connected to the spray assembly 41. The second stop valve 46 is installed on the spare inlet pipe group 45 and is used to connect or disconnect the spare inlet pipe group 45. When the detection result of the detection component 42 reaches a preset condition and the main inlet pipe group 43 cannot work, the second stop valve 46 is opened to connect the spare inlet pipe group 45, so that the fire extinguishing medium is introduced into the spray assembly 41 through the spare inlet pipe group 45 to perform fire extinguishing operations.

[0149] For example, the second stop valve 46 may be, but is not limited to, an electromagnetic stop valve.

[0150] In this way, when the main inlet pipe group 43 cannot work normally due to damage or other reasons, the spare inlet pipe group 45 and the second stop valve 46 can be activated, further improving the installation coefficient of the exhaust operation.

[0151] In some embodiments of the present application, Fig.10 As shown, two spray assemblies 41 are provided along the second direction Y, and the inlet ends of the two spray assemblies 41 are respectively connected to the same spare introduction pipe group 45. The spare introduction pipe group 45 is provided with a second stop valve 46 corresponding to the two spray assemblies 41, and the two second stop valves 46 respectively control whether the fire extinguishing medium in the two spray assemblies 41 is passed. In this way, when a fire occurs in a certain area, only the second stop valve 46 controlling the spray assembly 41 in the area can be opened, and the other spray assembly 41 can be stopped, which plays a role in saving materials. In addition, if both areas are on fire, the two second stop valves 46 are opened, which increases the range of spraying the fire extinguishing medium, thereby accelerating the efficiency of fire extinguishing.

[0152] For example, Fig.10As shown, the main inlet pipe group 43 includes a main inlet pipe and a main inlet joint 431 connected to the inlet end of the main inlet pipe, and the main inlet joint 431 is used to connect the pipeline supplying the fire extinguishing medium. The spare inlet pipe group 45 includes a spare inlet pipe and a spare inlet joint 451 connected to the inlet end of the spare inlet pipe, and the spare inlet joint 451 is used to connect the pipeline supplying the fire extinguishing medium. The main inlet pipe and the spare inlet pipe are both fixed to the exhaust mounting frame 8 through the fire extinguishing pipe fixing block 47.

[0153] In some embodiments of the present application, the cargo platform 1 is installed with a protective plate 5 , and the protective plate 5 is shielded above the fire extinguishing system 4 .

[0154] For example, Figure 4 , Figure 5 and Figure 7 As shown, an exhaust mounting frame 8 is installed on the top of the base frame 11 of the cargo platform 1 , and the fire extinguishing system 4 and the exhaust mechanism 2 are respectively installed on the exhaust mounting frame 8 , and the fire extinguishing system 4 is located above the exhaust mechanism 2 .

[0155] Exemplarily, the protection plate 5 is installed on the top of the exhaust mounting frame 8 to block the top of the fire extinguishing system 4.

[0156] In this way, the protection effect of the fire extinguishing system 4 is improved.

[0157] In some embodiments of the present application, Fig.11 As shown, the stacker further includes a frame 6 and a lifting mechanism 7. The cargo platform 1 and the lifting mechanism 7 are respectively arranged on the frame 6. The lifting mechanism 7 is configured to be able to drive the cargo platform 1 to rise and fall.

[0158] The specific structure of the lifting mechanism 7 can refer to the stacker in the prior art, and will not be described in detail here.

[0159] In this way, by setting the lifting mechanism 7, the lifting and lowering of the cargo platform 1 is realized, and the stacker can take the pallet 200 from different position heights or transport the pallet 200 to different position heights, thereby realizing the stacking function of the stacker.

[0160] The following is a brief introduction to the method for using the stacker provided in the embodiment of the present application:

[0161] A pallet 200 containing battery cells 100 placed on a shelf is transferred to a target location using a stacker.

[0162] First, a tray 200 containing battery cells 100 placed on a shelf is placed on a cargo platform 1;

[0163] Next, the exhaust mechanism 2 docks with the battery cell 100 in the tray 200 carried on the cargo platform 1 and performs an exhaust operation to discharge the gas in the battery cell 100 to the outside.

[0164] Once again, after the exhaust operation is completed, the lifting mechanism 7 drives the cargo platform 1 to lift to the target height of the target position and then stops lifting;

[0165] Finally, the pallet 200 of the cargo platform 1 is horizontally moved to the target position.

[0166] Specific examples of some embodiments of the present application are described below with reference to the accompanying drawings.

[0167] As a specific example, the stacker includes a fire extinguishing system cover (protective plate 5), a negative pressure exhaust component assembly (exhaust mechanism 2), a stacker loading platform (loading platform 1), a pallet lifting and positioning mechanism (pushing mechanism 3) and a fire fighting system (fire extinguishing system 4), wherein the negative pressure exhaust component assembly includes a frame (exhaust mounting frame 8) and an exhaust structure component (air suction component 23). The exhaust structure component includes a fixed block (fixed connector 26), an exhaust pipe (exhaust pipe 241), a cavity (accommodating cavity 22), a connecting pipe (suction pipe 231), an open valve type suction nozzle (suction nozzle 232), a discharge pipe (discharge pipe 251), a discharge pipe aggregation joint (second aggregation joint 252) and an exhaust pipe aggregation joint (first aggregation joint 242), etc. The pallet lifting and positioning mechanism includes a pallet lifting and positioning mechanism fixing frame (second guide mounting frame 13), a guide bar (guide bar 14), left and right limit plates (limit plates 322), an electric cylinder (lifting drive member 31) and a side limit plate (guide block 33), etc. The fire protection system is composed of a sprinkler (sprinkler 411), an electromagnetic shut-off valve (first shut-off valve 44) and a temperature and smoke sensor (detection element 42).

[0168] The fire extinguishing system cover is fixed to the negative pressure exhaust component assembly by bolts, which plays the role of enclosed space and isolation protection. The negative pressure exhaust component assembly is fixed to the stacker loading platform. The pallet lifting and positioning mechanism is fixed to the stacker loading platform by bolts. When the pallet is taken to the working position (loading position) by the fork (material loading plate 12) on the stacker loading platform, the electric cylinder and the left and right limit plates in the pallet lifting and positioning mechanism lift the pallet together, so that the valve-type suction nozzle in the negative pressure exhaust component assembly and the valve body (exhaust valve body 101) of the battery cell (battery cell 100) are engaged. At this time, the valve-type suction nozzle opens the valve body for exhaust. When the pallet lifting and positioning mechanism descends, the valve-type suction nozzle disengages from the valve body and the exhaust ends. In this process, the left and right limit plates and the side limit plates play the role of limiting the position of the pallet. The temperature and smoke sensor in the fire protection system senses the temperature rise and smoke, triggering the main fire protection (the whole consisting of the spray component 41, the nozzle 411, the detection component 42, the main inlet pipe group 43, and the first stop valve 44). The electromagnetic stop valve opens, and the fire extinguisher performs fire extinguishing operations through the main fire protection pipeline (main inlet pipe group 43) and the nozzle (nozzle 411). When the main fire protection system fails, the auxiliary fire protection (the whole consisting of the spray component 41, the nozzle 411, the detection component 42, the spare inlet pipe group 45, and the second stop valve 46) can be activated.
