[0002] This disclosure is based on Chinese patent application number 202410115999.8, application date January 29, 2024, and invention name “Elevator, battery production line and lifting method”, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this disclosure as a reference. Technical Field

[0003] The present disclosure relates to the technical field of battery manufacturing, and in particular to a hoist, a battery production line and a hoisting method. Background Art

[0004] New energy batteries are being used more and more widely in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also being increasingly used in energy storage fields.

[0005] During the battery manufacturing process, an elevator is used to lift or lower the trays used to transfer bare cells, enabling the transfer of trays between conveyor lines at different heights, thereby transferring the bare cells. The speed at which the elevator lifts or lowers the trays is related to the efficiency of battery forming. Therefore, increasing the transfer speed of the elevator is an important part of improving battery production efficiency.

[0006] In addition, simplifying the structure of the elevator is an effective means to reduce cost investment. Therefore, how to simplify the structure of the elevator while increasing the transfer speed of the elevator is one of the research topics in the industry.

[0007] Summary of the Invention

[0008] In order to solve the above technical problems, the present disclosure provides a lifting machine, a battery production line and a lifting method for improving transfer speed and simplifying the structure.

[0009] The present disclosure is achieved through the following technical solutions.

[0010] The first aspect of the present disclosure provides a lifting machine, comprising at least two lifting mechanisms, at least one lifting mechanism being used to perform a lifting operation for lifting a component to be transferred, and at least one lifting mechanism being used to perform a lowering operation for lowering a component to be transferred, and the lifting operation and the lowering operation can be performed simultaneously; the lifting mechanism comprises a power assembly and a bearing assembly, the bearing assembly is connected to the power assembly, the power assembly can drive the bearing assembly to rise or fall, the bearing assembly comprises a plurality of rollers that can rotate separately, and the tops of the plurality of rollers are used to carry the component to be transferred; by the rollers rotating in the same direction, the component to be transferred can be moved in a direction perpendicular to the rotation axis of the roller while contacting the tops of the rollers; the bearing assembly also comprises: a mounting member, the mounting member is connected to the output end of the power assembly, and the power assembly can drive the mounting member to rise or fall; a plurality of one-way rotating connecting members, the one-way rotating connecting members are respectively mounted on the mounting member, each roller is connected to each one-to-one rotating connecting member, and the roller can rotate unidirectionally relative to the mounting member through the one-way rotating connecting member.

[0011] When the elevator provided by the embodiment of the present disclosure is used in the process of transferring pallets in the battery production process, the empty pallet without bare battery cells is lifted or lowered by a lifting mechanism, and the full pallet carrying bare battery cells is lowered or lifted by another lifting mechanism, thereby realizing the transfer of pallets to achieve the transportation of bare battery cells. The lifting operation and the lowering operation can be carried out simultaneously, so that the operations of lifting and lowering the pallet are carried out at the same time, realizing two-way transfer and high transfer efficiency.

[0012] When the pallet moves toward the roller of the carrying component, the pallet itself has a certain initial velocity. When the pallet just contacts the roller, the rolling friction between the two will cause the roller to start rotating. The rotation of the roller can drive the pallet to continue moving forward, so that the pallet can maintain movement for a longer time, so that the pallet can be moved into place without the use of a pushing mechanism. Therefore, the pushing mechanism is eliminated, the structure of the elevator is simplified, and the time consumed in the pushing step of the pushing mechanism is also eliminated, so that the time for the pallet to enter the elevator is reduced, thereby improving the transfer efficiency of the elevator.

[0013] The setting of the one-way rotating connection allows the roller to rotate in only one direction. During the process of the part to be transferred entering the carrying assembly, the part to be transferred drives the roller to rotate in one direction. The tangential component of the speed at the top of the roller is consistent with the moving speed of the part to be transferred, which is conducive to the continued forward movement of the part to be transferred. Since the roller cannot rotate in the other direction, when the part to be transferred moves into place and is blocked, the roller will not rotate in the opposite direction, which can prevent the part to be transferred from rebounding, thereby improving the smoothness of the movement of the part to be transferred.

[0014] In some embodiments, the mounting member includes two mounting plates arranged opposite to each other along a first direction, and the sides of the two mounting plates facing each other are connected to a plurality of rollers spaced apart along a second direction. The first direction, the second direction, and the up and down directions intersect with each other in pairs, and the plate surfaces of the two mounting plates facing each other and the tops of the plurality of rollers define a receiving space for accommodating the components to be transferred.

[0015] Two opposing mounting plates allow rollers mounted thereon to support the components to be transferred at opposite ends of the bottom, thereby stably supporting the components. Furthermore, the two mounting plates are spaced apart in the first direction, ensuring that the components to be transferred are unobstructed during their movement into the accommodating space along the second direction, thereby facilitating the transfer of the components into the elevator. Furthermore, mounting plates are provided on opposite sides of the accommodating space, with the facing surfaces of the two mounting plates acting as position limiters for the components to be transferred, thereby enhancing the stability of the support assembly in supporting the components to be transferred.

[0016] In some embodiments, the one-way rotation connection comprises a one-way bearing.

[0017] The provision of the one-way bearing enables the roller to rotate in only one direction relative to the mounting plate, thereby preventing the component to be transferred from rebounding when it is moved into position.

[0018] In some embodiments, the roller comprises a rubber-coated roller.

[0019] The setting of the rubber-coated roller increases the friction between the roller and the part to be transferred, improves the interaction effect between the rubber-coated roller and the part to be transferred, thereby improving the efficiency of the part to be transferred entering the accommodating space. In addition, due to the increase in friction, the part to be transferred is further prevented from rebounding when being blocked.

[0020] In some embodiments, the power assembly includes: a first driving member; a transmission assembly connected to the output end of the first driving member, and a mounting plate connected to the transmission assembly; wherein the first driving member can drive two relative mounting plates to rise or fall synchronously through the transmission assembly.

[0021] The first driving member can drive the two opposite mounting plates to rise or fall synchronously through the transmission assembly, so that the components to be transferred carried by the rollers mounted on the mounting plates can be lifted and lowered smoothly.

[0022] In some embodiments, the transmission assembly includes a first belt transmission assembly and a second belt transmission assembly, and two relative mounting plates are respectively connected to the first belt transmission assembly and the second belt transmission assembly. The first driving member can drive the first belt transmission assembly and the second belt transmission assembly to move simultaneously, so as to drive the two relative mounting plates to rise or fall synchronously.

[0023] The two belt drive assemblies respectively drive the two mounting plates to rise and fall synchronously, thereby realizing the lifting and lowering of the parts to be transferred. Moreover, by using belt drive, the belt is not easily stretched to prevent affecting the accuracy of the lifting position, thereby improving the accuracy of the elevator's control of the lifting position of the parts to be transferred.

[0024] In some embodiments, the transmission assembly further includes a rotation transmission assembly, the two ends of which are respectively connected to the first belt transmission assembly and the second belt transmission assembly, and the rotation transmission assembly can transmit the movement of the first belt transmission assembly to the second belt transmission assembly.

[0025] In this way, two transmission components can be driven to move simultaneously by a first driving member, eliminating a driving member, thereby further simplifying the structure of the elevator and saving cost investment.

[0026] In some embodiments, the first belt transmission assembly includes: a first rotating shaft, a first driving member drivingly connected to the first rotating shaft; a first driving synchronous pulley mounted on the first rotating shaft and configured to rotate synchronously with the first rotating shaft; a first mounting shaft, the first mounting shaft and the first rotating shaft being spaced apart in the vertical direction; a first driven synchronous pulley mounted on the first mounting shaft and configured to rotate about the first mounting shaft; a first synchronous belt wound around the first driving synchronous pulley and the first driven synchronous pulley, the outer side surface of the first synchronous belt being provided with a plurality of mounting plates distributed at equal intervals along the belt extension direction;

[0027] The second belt drive assembly includes: a second rotating shaft, with both ends of the rotating transmission assembly respectively connected to the first rotating shaft and the second rotating shaft; a second active synchronous pulley, mounted on the second rotating shaft and configured to rotate synchronously with the second rotating shaft; a second mounting shaft, with the second mounting shaft and the second rotating shaft spaced apart in the upper and lower directions; a second driven synchronous pulley, mounted on the second mounting shaft and configured to rotate around the second mounting shaft; a second synchronous belt, wound around the second active synchronous pulley and the second driven synchronous pulley, and the outer side surface of the second synchronous belt is provided with a plurality of mounting plates equally spaced along the belt extension direction.

[0028] In this way, the mounting plate connected to the first and second synchronous belts rise and fall synchronously, allowing the load-bearing assembly to rise and fall smoothly. Furthermore, because both the first and second synchronous belts are connected to multiple, spaced-apart mounting plates, the multiple mounting plates on the same synchronous belt rise and fall into place in a uniform rhythm during transmission, improving the efficiency of transferring the components to be transferred.

[0029] In some embodiments, the rotation transmission assembly includes: a first right-angle connector, whose power input end is connected to the first rotating shaft; a connecting shaft, one end of which is connected to the power output end of the first right-angle connector; a second right-angle connector, whose power input end is connected to the other end of the connecting shaft, and the power output end of the second right-angle connector is connected to the second rotating shaft.

[0030] The arrangement of the first right-angle connector, the connecting shaft and the second right-angle connector enables the transmission of the rotation of the first rotating shaft to the second rotating shaft, and makes the structure of the rotation transmission assembly simple and the cost investment low.

[0031] In some embodiments, the first right-angle connector and the first rotating shaft are connected by a concave-convex fit; the second right-angle connector and the second rotating shaft are connected by a clamping fit.

[0032] The concave-convex matching method makes the connection between the two firm, and the holding method makes it possible to adjust the angle of the second rotating shaft first when the second right-angle connector is connected to the second rotating shaft, and then hold it tightly when the adjustment is appropriate. In this way, the installation angle of the second active synchronous wheel can be adjusted by adjusting the angle of the second rotating shaft, so that the installation angles of the second active synchronous wheel and the first active synchronous wheel are the same, so that the first synchronous belt and the second synchronous belt are completely opposite to each other in the first direction. In this way, the mounting plate connected to the first synchronous belt and the mounting plate connected to the second synchronous belt are completely opposite to each other in the first direction, so that the accommodating space is in a horizontal plane, thereby improving the stability of the load-bearing component to be transferred.

[0033] In some embodiments, the part to be transferred includes an empty pallet without any objects or a full pallet with objects, and the objects include battery components; the lifting mechanism for lifting operations is used to lift the full pallet, and the lifting mechanism for lowering operations is used to lower the empty pallet; or, the lifting mechanism for lifting operations is used to lift the empty pallet, and the lifting mechanism for lowering operations is used to lower the full pallet.

[0034] The elevator provided in this embodiment is used in the conveying operation of battery assemblies. The battery assemblies include bare cells and other components used to constitute battery cells. The structure of the elevator is simplified, the cost of transferring battery assemblies is reduced, and the transfer efficiency of battery assemblies is improved, thereby improving the manufacturing cost and manufacturing efficiency of battery cells.

[0035] In some embodiments, each lifting mechanism has an input portion and an output portion spaced apart in the up and down directions, and a pushing mechanism is provided corresponding to each output portion. The pushing mechanism can extend into the accommodating space that has been moved to the output portion along the second direction to push the components to be transferred in the accommodating space out of the accommodating space.

[0036] The push-out mechanism is used to push the components to be transferred that have been lifted to the output position out of the accommodating space, and to send the lifted components to be transferred out of the lifting mechanism so that the components to be transferred can enter the next process.

[0037] In some embodiments, the ejection mechanism includes: an ejection mounting seat; a second driving member, mounted on the ejection mounting seat; a telescopic mounting seat, connected to the output end of the second driving member, and the second driving member can drive the telescopic mounting seat to move back and forth along the second direction; a third driving member, mounted on the telescopic mounting seat; a pushing member, connected to the output end of the third driving member, and the third driving member can drive the pushing member to move back and forth along the up and down directions, the third driving member drives the pushing member to descend to the side of the accommodating space located at the output part, and the second driving member drives the pushing member to move along the second direction to the accommodating space located at the output part, so as to push the part to be transferred in the accommodating space out of the accommodating space.

[0038] During the ejection process, the third driving member drives the pusher to descend to the side of the receiving space at the output portion, and the second driving member drives the pusher to move along the second direction into the receiving space at the output portion to eject the component to be transferred from the receiving space. This ejection mechanism ejects the component to be transferred from the receiving space out of the receiving space, thereby ejecting the component to be transferred from the lifting mechanism to facilitate its entry into the next process. This ejection mechanism has a simple structure, low cost, and is easy to operate.

[0039] In some embodiments, the pushing member includes: a main body connected to the output end of the third driving member; two pushing parts respectively connected to the two ends of the bottom of the main body, and the pushing part includes a pushing surface for pushing the component to be transferred.

[0040] In this way, the two pushing parts push the component to be transferred at the same time, thereby improving the stability of the pushing and preventing the component to be transferred from tilting.

[0041] In some embodiments, an output mechanism is provided corresponding to each output position, and the output mechanism has a conveying path extending along the second direction. The conveying path of the output mechanism is arranged close to the output position corresponding to the output mechanism, and the pushing mechanism corresponding to the output position can push the component to be transferred located at the output position to the conveying path of the output mechanism corresponding to the output position.

[0042] The output mechanism cooperates with the ejection mechanism to output the parts to be transferred that have been lifted into place from the elevator, further improving the elevator's transfer function for the parts to be transferred.

[0043] In some embodiments, an input mechanism is provided corresponding to each input portion, and the input mechanism can input the component to be transferred into the accommodating space that has been moved to the input portion along the second direction.

[0044] The input mechanism is provided to deliver the components to be transferred from outside the elevator into the accommodating space of the elevator, so as to improve the transfer function of the elevator for the components to be transferred.

[0045] In some embodiments, the input mechanism has a conveying path extending along the second direction, and the conveying path of the input mechanism is disposed close to an input portion corresponding to the input mechanism.

[0046] The input mechanism transports the part to be transferred close to the input portion of the lifting mechanism. When the part to be transferred moves to partially contact the roller, it drives the roller to rotate. The tangential component of the speed of the top of the roller is consistent with the movement speed of the part to be transferred. Therefore, after the part to be transferred moves forward and completely separates from the input mechanism, the interaction between the roller and the part to be transferred facilitates the continued forward movement of the part to be transferred, allowing the part to be transferred to move forward into position. The part to be transferred can be moved into position through the interaction with the roller, eliminating the need for a pushing mechanism to push the part to be transferred forward throughout the entire process, simplifying the structure of the elevator and saving costs. Moreover, because the pushing step of the pushing mechanism is eliminated, the efficiency of the entry of the part to be transferred is improved, thereby improving the transfer efficiency.

[0047] A second aspect of the present disclosure provides a battery production line, comprising: a manufacturing machine for manufacturing battery components; a battery assembly device for assembling batteries using the battery components; and the above-mentioned elevator; wherein at least one lifting mechanism of the elevator lifts or lowers a solid pallet carrying the battery components to transfer the solid pallet to the battery assembly device, and at least one lifting mechanism of the elevator lowers or lifts an empty pallet removed from the battery assembly device to transfer the empty pallet to the manufacturing machine.

[0048] The battery production line provided by the embodiment of the present disclosure includes the above-mentioned elevator. Since the structure of the elevator is simplified and the transfer efficiency of the elevator is improved, the structure of the battery production line provided by the embodiment of the present disclosure is simplified and the production efficiency of the battery is improved.

[0049] The third aspect of the present disclosure provides a lifting method, which uses a lifting machine to lift multiple components to be transferred and lower another multiple components to be transferred, the lifting machine comprising at least two lifting mechanisms, at least one lifting mechanism being used to lift the components to be transferred, and at least one lifting mechanism being used to lower the components to be transferred, and the lifting operation and the lowering operation can be performed simultaneously; the lifting mechanism comprises a power assembly and a bearing assembly, the bearing assembly is connected to the power assembly, the power assembly can drive the bearing assembly to rise or fall, the bearing assembly comprises a plurality of rollers, the tops of the plurality of rollers are used to carry the components to be transferred; the rollers are rotated in the same direction so that the components to be transferred can be moved in a direction perpendicular to the rotation axis of the rollers while contacting the tops of the rollers; the bearing assembly further comprises: a mounting member, the mounting member is connected to the output end of the power assembly, the power assembly can drive the mounting member to rise or fall; a plurality of one-way rotating connectors, the one-way rotating connectors are respectively mounted on the mounting member, each of the rollers is connected to each of the one-way rotating connectors in a one-to-one correspondence, and the rollers can rotate unidirectionally relative to the mounting member through the one-way rotating connector;

[0050] Improvement methods include:

[0051] a feeding step of feeding a component to be transferred onto the roller of the lifting mechanism for lifting, and feeding another component to be transferred onto the roller of the lifting mechanism for lowering;

[0052] The lifting step is to use the lifting mechanism for lifting to lift the carried component to be transferred, and to use the lifting mechanism for lowering to lower the carried component to be transferred.

[0053] When the lifting method provided by the embodiment of the present disclosure is applied to transfer pallets in the battery production process, an empty pallet that does not carry bare cells is lifted or lowered by a lifting mechanism, and a full pallet that carries bare cells is lowered or lifted by another lifting mechanism, thereby realizing the transfer of pallets to achieve the transportation of bare cells. The lifting operation and the lowering operation can be carried out simultaneously, so that the operations of lifting and lowering the pallet are carried out simultaneously, realizing two-way transfer and high transfer efficiency.

[0054] When the pallet moves toward the roller of the carrying component, the pallet itself has a certain initial velocity. When the pallet just contacts the roller, the rolling friction between the two will cause the roller to start rotating. The rotation of the roller can drive the pallet to continue moving forward, so that the pallet can maintain movement for a longer time, so that the pallet can be moved into place without the use of a pushing mechanism. Therefore, the pushing mechanism is eliminated, the structure of the elevator is simplified, and the time consumed by the pushing step of the pushing mechanism is also eliminated, so that the time for the pallet to enter the elevator is reduced, thereby improving the transfer efficiency of the elevator.

[0055] In some embodiments, each lifting mechanism has an input portion and an output portion spaced apart in the vertical direction, and an input mechanism is provided for each input portion.

[0056] The feeding steps include:

[0057] a step of placing the component to be transferred, placing the component to be transferred onto the input end of the input mechanism;

[0058] The conveying step is that the input mechanism conveys the components to be transferred to the output end of the input mechanism;

[0059] In the transfer step, the input mechanism transports the components to be transferred at its output end to the rollers of the carrying assembly.

[0060] In this way, the components to be transferred are fed from outside the elevator into the accommodation space of the elevator through the input mechanism, thereby improving the elevator's transfer function for the components to be transferred.

[0061] In some embodiments, the part to be transferred includes an empty pallet without any objects or a full pallet with objects, and the objects include battery components; in the lifting step, a lifting mechanism for lifting is used to lift the full pallet, and a lifting mechanism for lowering is used to lower the empty pallet; or, a lifting mechanism for lifting is used to lift the empty pallet, and a lifting mechanism for lowering is used to lower the full pallet.

[0062] The lifting method provided in this embodiment is applied to the transportation of battery assemblies, which include bare cells and other components used to constitute battery cells. The structure of the elevator is simplified, which reduces the cost of transferring battery assemblies. The lifting method improves the transfer efficiency of battery assemblies, thereby improving the manufacturing cost and manufacturing efficiency of battery cells.

[0063] In some embodiments, after the step of increasing, the method further comprises:

[0064] In the discharging step, the lifting mechanism used for lifting operation pushes the lifted component to be transferred from the roller to the outside of the lifting mechanism, and the lifting mechanism used for lowering operation pushes the lowered component to be transferred from the roller to the outside of the lifting mechanism.

[0065] After the parts to be transferred are moved into position, they are moved out of the lifting mechanism, which further improves the transfer function of the parts to be transferred by the elevator.

[0066] In some embodiments, each lifting mechanism has an input portion and an output portion spaced apart in the vertical direction, and a push-out mechanism and an output mechanism are provided corresponding to each output portion.

[0067] The discharging steps include:

[0068] In the pushing step, when the carrier assembly moves to the output position, the power assembly stops driving, and the pushing mechanism pushes the components to be transferred in the accommodating space of the carrier assembly to the conveying path of the output mechanism;

[0069] In the output step, the output mechanism transports the components to be transferred out of the lifting mechanism.

[0070] The output mechanism cooperates with the ejection mechanism to output the parts to be transferred that have been lifted into place from the elevator, further improving the elevator's transfer function for the parts to be transferred.

[0097] Hereinafter, the present disclosure will be described in detail.

[0098] Currently, new energy batteries are increasingly being used in everyday life and industry. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in a variety of fields such as aerospace. As the application of power batteries continues to expand, market demand is also growing.

[0099] Batteries are composed of multiple bare cells. During the battery manufacturing process, elevators are used to raise or lower the trays used to transfer the bare cells, enabling the transfer of the trays between conveyor lines at different heights, thereby transferring the bare cells. The speed at which the elevator raises or lowers the trays is related to the efficiency of battery forming. Therefore, increasing the elevator's transfer speed is a key part of improving battery production efficiency. In addition, simplifying the elevator's structure is an effective way to reduce cost investment. Therefore, how to improve the elevator's transfer speed while simplifying the elevator's structure is one of the research topics in the industry.

[0100] The inventors of the present disclosure noticed that the supporting structure for supporting the pallet in the existing elevator is a plate-like structure. When the pallet is pushed onto the plate-like structure, it is in direct contact with the upper surface of the plate-like structure. The pallet needs to overcome a relatively large sliding friction force during the movement. From the moment the pallet contacts the plate-like structure, it cannot move forward to the target position without being pushed forward. Therefore, it is necessary to set up a pushing mechanism to push the pallet onto the plate-like structure and move it to the target position. Setting up the pushing mechanism makes the structure of the elevator more complicated and the investment cost is higher. Moreover, the pushing step of the pushing mechanism will also consume a certain amount of time, affecting the time for pushing the pallet in, thereby affecting the transfer efficiency of the elevator.

[0101] The inventors of the present invention have discovered through research that a plurality of rollers are used to carry the pallet instead of the existing plate-like structure. The pallet itself has a certain initial velocity when moving toward the rollers. When the pallet just contacts the rollers, the rolling friction between the two will cause the rollers to start rotating. The rotation of the rollers can drive the pallet to continue moving forward, so that the pallet can maintain movement for a longer time, so that the pallet can be moved into place without the use of a pushing mechanism. Therefore, the pushing mechanism is eliminated, the structure of the elevator is simplified, and the time consumed in the pushing step of the pushing mechanism is also eliminated, so that the time for the pallet to enter the elevator is reduced, thereby improving the transfer efficiency of the elevator.

[0102] Based on such a design concept, the inventor of the present disclosure designed an elevator, which includes at least two lifting mechanisms, at least one lifting mechanism is used to perform lifting operations for lifting the components to be transferred, and at least one lifting mechanism is used to perform lowering operations for lowering the components to be transferred, and the lifting operations and the lowering operations can be performed simultaneously; the lifting mechanism includes a power component and a load-bearing component, the load-bearing component is connected to the power component, the power component can drive the load-bearing component to rise or fall, and the load-bearing component includes a plurality of rollers that can rotate separately, and the tops of the plurality of rollers are used to carry the components to be transferred; by the rollers rotating in the same direction, the components to be transferred can be moved in a direction perpendicular to the rotation axis of the roller while contacting the tops of the rollers.

[0103] When the elevator is used in the process of transferring pallets in the battery production process, the pallet itself has a certain initial velocity when it moves toward the roller that carries the component. When the pallet just contacts the roller, the rolling friction between the two will cause the roller to start rotating. The rotation of the roller can drive the pallet to continue moving forward, so that the pallet can maintain movement for a longer time, so that the pallet can move into place by itself without the use of a pushing mechanism. Therefore, the pushing mechanism is eliminated, the structure of the elevator is simplified, and the time consumed in the pushing step of the pushing mechanism is also eliminated, so that the time for the pallet to enter the lifting mechanism is reduced, thereby improving the transfer efficiency of the elevator.

[0104] The elevator provided in the embodiment of the present disclosure can be used, but is not limited to, to transfer pallets for producing batteries. It can also be used to transfer pallets for producing other products. Of course, it can also be used to transfer objects other than pallets.

[0105] Hereinafter, some embodiments of the present disclosure will be described in detail with reference to FIG. 1 to FIG. 14 .

[0107] In some embodiments of the present disclosure, for ease of explanation, a first direction, a second direction, and an up-down direction are set, and the first direction, the second direction, and the up-down direction are directions that intersect with each other, and here, intersecting with each other includes intersecting perpendicularly with each other. For ease of understanding the embodiments of the present disclosure, in the embodiments shown in Figures 1 to 8, the first direction, the second direction, and the up-down direction are directions that intersect with each other perpendicularly for explanation, but those skilled in the art should understand that the embodiments of the present disclosure are not limited to the case where the three directions intersect with each other perpendicularly. For ease of explanation, as shown by the arrows in Figures 1 to 8, 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 up-down direction. Sometimes the direction indicated by arrow Z along the up-down direction is also referred to as "above", and the opposite direction is referred to as "below".

[0108] As shown in Figures 1 to 4, an embodiment of the present disclosure provides a hoist, which includes at least two lifting mechanisms 2, at least one lifting mechanism 2 is used to perform a lifting operation of lifting the component to be transferred 100, and at least one lifting mechanism 2 is used to perform a lowering operation of the component to be transferred 100, and the lifting operation and the lowering operation can be performed simultaneously; the lifting mechanism 2 includes a power component and a bearing component 22, the bearing component 22 is connected to the power component, the power component can drive the bearing component 22 to rise or fall, and the bearing component 22 includes a plurality of rollers 221 that can rotate separately, and the tops of the plurality of rollers 221 are used to carry the component to be transferred 100; by the rollers rotating in the same direction, the component to be transferred 100 can be moved in a direction perpendicular to the rotation axis of the roller 221 while contacting the top of the roller.

[0109] During the lifting and lowering operations, the power assembly drives the carrying assembly 22 to rise or fall, and the rollers 221 of the carrying assembly 22 carry the component to be transferred 100 , thereby realizing the lifting or lowering function of the lifting mechanism 2 on the component to be transferred 100 .

[0110] When the elevator provided by the embodiment of the present disclosure is used in the process of transferring pallets in the battery production process, the empty pallet without bare battery cells is lifted or lowered by a lifting mechanism, and the full pallet carrying bare battery cells is lowered or lifted by another lifting mechanism, thereby realizing the transfer of pallets to achieve the transportation of bare battery cells. The lifting operation and the lowering operation can be carried out simultaneously, so that the operations of lifting and lowering the pallet are carried out at the same time, realizing two-way transfer and high transfer efficiency.

[0111] When the pallet moves toward the roller 221 of the supporting assembly 22, the pallet itself has a certain initial velocity. When the pallet just contacts the roller 221, the rolling friction between the two will cause the roller 221 to start rotating. The rotation of the roller 221 can drive the pallet to continue moving forward, so that the pallet can maintain movement for a longer time, so that the pallet can be moved into place without the use of a pushing mechanism. Therefore, the pushing mechanism is eliminated, the structure of the elevator is simplified, and the time consumed by the pushing step of the pushing mechanism is also eliminated, so that the time it takes for the pallet to enter the elevator is reduced, thereby improving the transfer efficiency of the elevator.

[0112] In some embodiments of the present disclosure, the supporting assembly 22 also includes a mounting member and a plurality of one-way rotating connecting members. The mounting member is connected to the output end of the power assembly, and the power assembly can drive the mounting member to rise or fall; the one-way rotating connecting members are respectively installed on the mounting member, and each roller is connected to each one-way rotating connecting member one by one. The roller can rotate unidirectionally relative to the mounting member through the one-way rotating connecting member.

[0113] The setting of the one-way rotating connection allows the roller to rotate in only one direction. When the part 100 to be transferred enters the carrying assembly 22, the part 100 to be transferred drives the roller 221 to rotate in one direction. The tangential component of the speed of the top of the roller 221 is consistent with the moving speed of the part 100 to be transferred, which is conducive to the continued forward movement of the part 100 to be transferred. Since the roller 221 cannot rotate in the other direction, when the part 100 to be transferred is moved into place and is blocked, the roller 221 will not rotate in the opposite direction, which can prevent the part 100 to be transferred from rebounding, thereby improving the smoothness of the lifting and lowering of the part 100 to be transferred.

[0114] In some embodiments of the present disclosure, the mounting member includes two mounting plates 222 arranged opposite to each other along a first direction, and the sides of the two mounting plates 222 facing each other are connected to a plurality of rollers 221 spaced apart along a second direction. The first direction, the second direction, and the up and down directions intersect with each other in pairs, and the plate surfaces of the two mounting plates 222 facing each other and the tops of the plurality of rollers 221 define a accommodating space for accommodating the component 100 to be transferred.

[0115] Two opposing mounting plates 222 allow the rollers 221 mounted thereon to support the respective opposite ends of the bottom of the component 100 to be transferred, thereby stably supporting the component 100 to be transferred. Furthermore, the two mounting plates 222 are spaced apart in the first direction, ensuring that the component 100 to be transferred is unobstructed during its movement along the second direction into the accommodating space, thereby facilitating the transfer of the component 100 into the elevator. Furthermore, mounting plates 222 are provided on opposite sides of the accommodating space, with the facing surfaces of the two mounting plates 222 acting as position limiters for the component 100 to be transferred, thereby enhancing the stability of the support assembly 22 in supporting the component 100 to be transferred.

[0116] In some embodiments of the present disclosure, the one-way rotation connection includes a one-way bearing.

[0117] A one-way bearing is a bearing that can rotate freely in one direction but is locked in the other direction.

[0118] Regarding the selection of the one-way bearing, as long as it is suitable for installation and can be adapted to be connected to the roller 221, the present disclosure has no special limitation on it, and it can be homemade or purchased from the market.

[0119] The provision of the one-way bearing enables the roller 221 to rotate in only one direction relative to the mounting plate 222 , thereby preventing the component 100 to be transferred from rebounding when being moved into position.

[0120] In some embodiments of the present disclosure, the roller 221 comprises a rubber-coated roller.

[0121] The provision of the rubber-coated roller increases the friction between the roller 221 and the component to be transferred 100, thereby improving the effect of the interaction between the roller 221 and the component to be transferred 100, thereby improving the efficiency of the component to be transferred 100 entering the accommodating space. In addition, due to the increase in friction, the component to be transferred 100 is further prevented from rebounding when being blocked.

[0122] In some embodiments of the present disclosure, the roller 221 comprises a cylindrical roller.

[0123] A cylindrical roller is a roller whose outer circumference includes a cylindrical surface.

[0124] The use of cylindrical rollers increases the contact area between the roller 221 and the component to be transferred 100 , improves the interaction effect between the roller 221 and the component to be transferred 100 , and thus improves the efficiency of the component to be transferred 100 entering the accommodating space.

[0125] In some embodiments of the present disclosure, the roller 221 is connected to a rotation driving member, which can drive the roller 221 to rotate. The rotation driving member includes a rotary motor.

[0126] The rotation driving member is connected to the multiple rollers 221 through transmission members such as belts and transmission wheels, thereby achieving simultaneous rotation driving of the multiple rollers 221.

[0127] In this way, after the component 100 to be transferred is transmitted to the roller 221, the roller 221 rotates itself, which can generate friction on the component 100 to be transferred, driving the component 100 to be transferred forward, thereby accelerating the efficiency of the component 100 to be transferred entering the accommodating space, thereby improving the tray transfer efficiency.

[0128] In some embodiments of the present disclosure, as shown in Figures 3 to 6, the power assembly includes a first driving member 211 and a transmission assembly, the transmission assembly is connected to the output end of the first driving member 211, and the supporting assembly 22 is connected to the transmission assembly; wherein, the first driving member 211 can drive two relative mounting plates 222 to rise or fall synchronously through the transmission assembly.

[0129] The first driving member 211 can drive the two opposite mounting plates 222 to rise or fall synchronously through the transmission assembly, so that the component 100 to be transferred carried by the roller 221 mounted on the mounting plate 222 can be lifted and lowered smoothly.

[0130] In some embodiments of the present disclosure, the transmission assembly includes a first belt transmission assembly 2121 and a second belt transmission assembly 2122, and two relative mounting plates 222 are respectively connected to the first belt transmission assembly 2121 and the second belt transmission assembly 2122. The first driving member 211 can drive the first belt transmission assembly 2121 and the second belt transmission assembly 2122 to move simultaneously, so as to drive the two relative mounting plates 222 to rise or fall synchronously.

[0131] The two belt drive assemblies respectively drive the two mounting plates 222 to rise and fall synchronously, thereby realizing the lifting and lowering of the transfer component 100. Moreover, by using belt drive, the belt is not easily stretched to prevent affecting the accuracy of the lifting position, thereby improving the accuracy of the elevator in controlling the lifting position of the transfer component 100.

[0132] In some embodiments of the present disclosure, the transmission assembly also includes a rotating transmission assembly 2123, the two ends of which are respectively connected to the first belt transmission assembly 2121 and the second belt transmission assembly 2122, and the rotating transmission assembly 2123 can transmit the movement of the first belt transmission assembly 2121 to the second belt transmission assembly 2122.

[0133] The first driving member 211 is connected to the first belt transmission component 2121, and can drive the first belt transmission component 2121 to move, thereby driving the mounting plate 222 connected to the first belt transmission component 2121 to rise or fall. At the same time, the first belt transmission component 2121 drives the second belt transmission component 2122 to move by rotating the transmission component 2123, thereby driving the mounting plate 222 connected to the second belt transmission component 2122 to rise or fall, thereby making the two relative mounting plates 222 rise or fall synchronously.

[0134] In this way, two transmission components can be driven to move simultaneously by a first driving member 211, eliminating a driving member, thereby further simplifying the structure of the elevator and saving cost investment.

[0135] In some embodiments of the present disclosure, the first belt transmission assembly 2121 includes a first rotating shaft 21211, a first active synchronous pulley 21212, a first mounting shaft, a first driven synchronous pulley and a first synchronous belt 21213, the first driving member 211 is drivingly connected to the first rotating shaft 21211; the first active synchronous pulley 21212 is mounted on the first rotating shaft 21211 and is configured to rotate synchronously with the first rotating shaft 21211; the first mounting shaft and the first rotating shaft 21211 are spaced apart in the upper and lower directions; the first driven synchronous pulley is mounted on the first mounting shaft and is configured to rotate around the first mounting shaft; the first synchronous belt 21213 is wound around the first active synchronous pulley 21212 and the first driven synchronous pulley, and the outer side surface of the first synchronous belt 21213 is provided with a plurality of mounting plates 222 distributed at equal intervals along the belt extension direction.

[0136] During the lifting operation, the first driving member 211 drives the first rotating shaft 21211 to rotate, and the first active synchronous pulley 21212 rotates synchronously with the first rotating shaft 21211. The first active synchronous pulley 21212 drives the first synchronous belt 21213 to transmit, thereby driving the installation plate 222 connected to the first synchronous belt 21213 to move. The first installation shaft and the first rotating shaft 21211 are spaced apart in the vertical direction, so that a portion of the first synchronous belt 21213 extends in the vertical direction, another portion is wound around the first active synchronous pulley 21212, and another portion is wound around the first driven synchronous pulley, thereby driving the installation plate 222 connected to the first synchronous belt 21213 to rise, pass around the first driven synchronous pulley, descend, and pass around the first active synchronous pulley 21212 in a cycle.

[0137] The second belt transmission assembly 2122 includes a second rotating shaft 21221, a second active synchronous pulley 21222, a second mounting shaft, a second driven synchronous pulley and a second synchronous belt 21223. The two ends of the rotating transmission assembly 2123 are respectively connected to the first rotating shaft 21211 and the second rotating shaft 21221; the second active synchronous pulley 21222 is mounted on the second rotating shaft 21221 and is configured to rotate synchronously with the second rotating shaft; the second mounting shaft and the second rotating shaft 21221 are spaced apart in the upper and lower directions; the second driven synchronous pulley is mounted on the second mounting shaft and is configured to rotate around the second mounting shaft; the second synchronous belt 21223 is wound around the second active synchronous pulley 21222 and the second driven synchronous pulley, and the outer side surface of the second synchronous belt 21223 is provided with a plurality of mounting plates 222 distributed at equal intervals along the belt extension direction.

[0138] During a lifting operation, the rotation transmission assembly 2123 transmits the rotation of the first rotating shaft 21211 to the second rotating shaft 21221. The rotation of the second rotating shaft 21221 drives the second active synchronous pulley 21222 to rotate, thereby driving the second synchronous belt 21223 to transmit the movement, thereby driving the installation plate 222 connected to the second synchronous belt 21223 to move. The second installation shaft and the second rotating shaft 21221 are spaced apart in the vertical direction, so that a portion of the second synchronous belt 21223 extends in the vertical direction, another portion is wound around the second active synchronous pulley 21222, and another portion is wound around the second driven synchronous pulley, thereby driving the installation plate 222 connected to the second synchronous belt 21223 to rise, pass around the second driven synchronous pulley, descend, and pass around the second active synchronous pulley 21222 in a cycle.

[0139] It should be noted that, in the lifting mechanism 2 used for lifting operations, the part of the first synchronous belt 21213 that rises during the transmission process is arranged opposite to the part of the second synchronous belt 21223 that rises during the transmission process. In this way, the multiple mounting plates 222 connected to the rising part of the first synchronous belt 21213 and the multiple mounting plates 222 connected to the rising part of the second synchronous belt 21223 are arranged one by one opposite to each other in the first direction. In this way, a plurality of accommodating spaces are formed, which are spaced apart in the up and down directions. The parts 100 to be transferred placed in the accommodating spaces rise in sequence under the transmission action of the first synchronous belt 21213 and the second synchronous belt 21223. In the lifting mechanism 2 used for performing the descending operation, the part of the first synchronous belt 21213 that descends during the transmission process is arranged opposite to the part of the second synchronous belt 21223 that descends during the transmission process. In this way, the multiple mounting plates 222 connected to the descending part of the first synchronous belt 21213 and the multiple mounting plates 222 connected to the descending part of the second synchronous belt 21223 are arranged one by one opposite to each other in the first direction. In this way, a plurality of accommodating spaces are formed, which are spaced apart in the up and down directions. The parts 100 to be transferred placed in the accommodating spaces descend in sequence under the transmission action of the first synchronous belt 21213 and the second synchronous belt 21223.

[0140] In this way, the mounting plate 222 connected to the first synchronous belt 21213 and the mounting plate 222 connected to the second synchronous belt 21223 rise or fall synchronously, allowing the carrier assembly 22 to rise or fall smoothly. In addition, because the first synchronous belt 21213 and the second synchronous belt 21223 are both connected to multiple mounting plates 222 spaced apart, multiple spaced apart accommodation spaces are formed between the first synchronous belt 21213 and the second synchronous belt 21223. Consequently, during the transmission of the first synchronous belt 21213 and the second synchronous belt 21223, the components 100 to be transferred accommodated in the multiple accommodation spaces rise or fall into place in sequence at a uniform rhythm, thereby improving the transfer efficiency of the components 100 to be transferred.

[0141] In some embodiments of the present disclosure, as shown in Figures 5 and 6, the rotation transmission assembly 2123 includes a first right-angle connector 21231, a connecting shaft 21232 and a second right-angle connector 21233, the power input end of the first right-angle connector 21231 is connected to the first rotating shaft 21211; one end of the connecting shaft 21232 is connected to the power output end of the first right-angle connector 21231; the power input end of the second right-angle connector 21233 is connected to the other end of the connecting shaft 21232, and the power output end of the second right-angle connector 21233 is connected to the second rotating shaft 21221.

[0142] A right-angle connector is a device used to connect two mutually perpendicular rotating shafts and transmit the rotational motion of one rotating shaft to the other rotating shaft. The connector has a power input end and a power output end. The power input end is used to connect the active rotating shaft, and the power output end is used to connect the driven rotating shaft.

[0143] The arrangement of the first right-angle connector 21231 , the connecting shaft 21232 and the second right-angle connector 21233 enables the transmission of the rotation of the first rotating shaft 21211 to the second rotating shaft 21221 , and makes the structure of the rotating transmission assembly 2123 simple and the cost investment low.

[0144] In some embodiments of the present disclosure, the first driving member 211 includes a servo motor.

[0145] The servo motor is convenient for controlling the driving stroke and speed, thereby well controlling the lifting stroke and speed of the component 100 to be transferred.

[0146] In some embodiments of the present disclosure, the first right-angle connector 21231 and the first rotating shaft 21211 are connected by a concave-convex fit; the second right-angle connector 21233 and the second rotating shaft 21221 are connected by a clamping fit.

[0147] The concave-convex matching method means that the outer surface of the first rotating shaft 21211 is provided with a groove or a protrusion, and the inner wall of the first right-angle connector 21231 is provided with a protrusion or a groove. In the first rotating shaft 21211 and the first right-angle connector 21231, the groove of one and the protrusion of the other are matched, which limits the relative rotation of the first right-angle connector 21231 and the first rotating shaft 21211, thereby making the two firmly connected.

[0148] The clamping method refers to a clamping structure provided in the second rotating shaft 21221. The clamping structure clamps the second rotating shaft 21221. During the installation process, the second rotating shaft 21221 can be rotated to adjust the angle of the second rotating shaft 21221. After the angle is adjusted appropriately, the clamping is performed. Exemplarily, the clamping structure includes a brake.

[0149] The concave-convex matching method makes the connection between the two firm, and the clamping method makes it possible to adjust the angle of the second rotating shaft 21221 first when the second right-angle connector 21233 is connected to the second rotating shaft 21221, and then clamp it when the adjustment is appropriate. In this way, the installation angle of the second active synchronous wheel 21222 can be adjusted by adjusting the angle of the second rotating shaft 21221, so that the installation angle of the second active synchronous wheel 21222 and the first active synchronous wheel 21212 are the same, so that the first synchronous belt 21213 and the second synchronous belt 21223 are completely opposite in the first direction. In this way, the mounting plate 222 connected to the first synchronous belt 21213 and the mounting plate 222 connected to the second synchronous belt 21223 are completely opposite in the first direction, so that the accommodating space is in the horizontal plane, thereby improving the stability of the load-bearing component 100 to be transferred.

[0150] In some embodiments of the present disclosure, the part to be transferred 100 includes an empty pallet without carrying objects or a full pallet carrying objects, and the objects include battery components; the lifting mechanism 2 for lifting operations is used to lift the full pallet, and the lifting mechanism 2 for lowering operations is used to lower the empty pallet.

[0151] For example, as shown in FIG1 , the arrow in FIG1 indicates the direction of movement of the pallet. The lifting mechanism 2 on the right side is used to lift a full pallet, and the lifting mechanism 2 on the left side is used to lower an empty pallet.

[0152] The input part of the lifting mechanism 2 for descending receives the empty pallet, the empty pallet descends to the output part and is sent out of the lifting mechanism 2. After being output, the empty pallet enters the equipment for manufacturing battery components and receives the manufactured battery components to become a solid pallet carrying battery components. The solid pallet is transported to the lifting mechanism 2 for lifting. The input part of the lifting mechanism 2 receives the solid pallet, then lifts the solid pallet to the output part and sends it out of the lifting mechanism 2. After being output, the solid pallet enters the equipment for assembling battery cells. After the battery components in the solid pallet are taken away by the equipment for assembling battery cells, an empty pallet remains. The empty pallet is transported to the lifting mechanism 2 for descending. The pallets are transferred in this cycle to realize the transportation of battery components.

[0153] In some embodiments of the present disclosure, the lifting mechanism 2 for performing lifting operations is used to lift an empty pallet, and the lifting mechanism 2 for performing lowering operations is used to lower a full pallet.

[0154] The input part of the lifting mechanism 2 for lifting receives the empty pallet, lifts it to the output part, and sends it out of the lifting mechanism 2. After being output, the empty pallet enters the equipment for manufacturing battery components, and receives the manufactured battery components to become a solid pallet carrying battery components. The solid pallet is transported to the lifting mechanism 2 for lowering. The input part of the lifting mechanism 2 receives the solid pallet, and then lowers the solid pallet to the output part and sends it out of the lifting mechanism 2. After being output, the solid pallet enters the equipment for assembling battery cells. After the battery components in the solid pallet are taken away by the equipment for assembling battery cells, an empty pallet remains. The empty pallet is transported to the lifting mechanism 2 for lifting. The pallets are transferred in this cycle to realize the transportation of battery components.

[0155] The elevator provided in this embodiment is used in the conveying operation of battery assemblies. The battery assemblies include bare cells and other components used to constitute battery cells. The structure of the elevator is simplified, the cost of transferring battery assemblies is reduced, and the transfer efficiency of battery assemblies is improved, thereby improving the manufacturing cost and manufacturing efficiency of battery cells.

[0156] Although not shown, a bare cell generally includes an electrode assembly. This assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of the bare cell, active ions are embedded in and extracted from the positive and negative electrodes. The separator, placed between the positive and negative electrodes, prevents short circuits between the positive and negative electrodes while allowing the active ions to pass through.

[0157] In some embodiments of the present disclosure, the electrode assembly is provided with tabs, which can conduct current from the electrode assembly. The tabs include positive tabs and negative tabs.

[0158] In some embodiments of the present disclosure, as shown in Figure 1, each lifting mechanism 2 has an input part and an output part spaced apart in the up and down directions, and a pushing mechanism 3 is provided corresponding to each output part. The pushing mechanism 3 can extend into the accommodating space that has been moved to the output part along the second direction to push the part to be transferred 100 in the accommodating space out of the accommodating space.

[0159] The input part is the upper limit position or the lower limit position of the lifting stroke of the component to be transferred 100 carried by the carrying assembly 22, and the output part is the lower limit position or the upper limit position of the lifting stroke of the component to be transferred 100 carried by the carrying assembly 22. After the component to be transferred 100 is sent to the input part, the component to be transferred 100 starts to lift, and after the component to be transferred 100 moves to the output part, the component to be transferred 100 is sent out of the lifting mechanism 2.

[0160] The push-out mechanism 3 is configured to push the component 100 to be transferred that has been lifted to the output position out of the accommodating space, and to deliver the lifted component 100 to be transferred out of the lifting mechanism 2 so that the component 100 to be transferred can enter the next process.

[0161] In some embodiments of the present disclosure, as shown in Figures 7 and 8, the ejection mechanism 3 includes an ejection mounting seat 31, a second driving member 32, a telescopic mounting seat 33, a third driving member 34 and a pushing member 35. The second driving member 32 is installed on the ejection mounting seat 31; the telescopic mounting seat 33 is connected to the output end of the second driving member 32, and the second driving member 32 can drive the telescopic mounting seat 33 to reciprocate along the second direction; the third driving member 34 is installed on the telescopic mounting seat 33; the pushing member 35 is connected to the output end of the third driving member 34, and the third driving member 34 can drive the pushing member 35 to reciprocate along the up and down directions. The third driving member 34 drives the pushing member 35 to descend to the side of the accommodating space located at the output part, and the second driving member 32 drives the pushing member 35 to move along the second direction to the accommodating space located at the output part, so as to push the component 100 to be transferred in the accommodating space out of the accommodating space.

[0162] During the process of pushing out the component 100 to be transferred, the third driving member 34 drives the pushing member 35 to descend to the side of the accommodating space located at the output part, and the second driving member 32 drives the pushing member 35 to move along the second direction to the accommodating space located at the output part, so as to push the component 100 to be transferred in the accommodating space out of the accommodating space, thereby pushing the component 100 to be transferred out of the lifting mechanism 2, so that the component 100 to be transferred can enter the next process.

[0163] In some embodiments of the present disclosure, the second driving member 32 includes a linear motor or a cylinder; the third driving member 34 includes a linear motor or a cylinder.

[0164] In some embodiments of the present disclosure, the pushing member 35 includes a main body 351 and two pushing parts 352, the main body 351 is connected to the output end of the third driving member 34; the two pushing parts 352 are respectively connected to the two ends of the bottom of the main body 351, and the pushing part 352 includes a pushing surface for pushing the component 100 to be transferred.

[0165] In this way, the two pushing parts 352 push the component to be transferred 100 at the same time, thereby improving the stability of the pushing and preventing the component to be transferred 100 from tilting.

[0166] In some embodiments of the present disclosure, as shown in FIG. 1 and FIG. 5 , an input mechanism 4 is provided corresponding to each input portion, and the input mechanism 4 can input the component 100 to be transferred into the accommodating space that has been moved to the input portion along the second direction.

[0167] The input mechanism 4 is provided to deliver the components 100 to be transferred from outside the elevator into the accommodation space of the elevator, so as to improve the elevator's transfer function for the components 100 to be transferred.

[0168] In some embodiments of the present disclosure, the input mechanism 4 has a conveying path extending along the second direction, and the conveying path of the input mechanism 4 is arranged close to the input position corresponding to the input mechanism 4.

[0169] The input mechanism 4 is a conveying mechanism, which is a mechanical device that transports materials along a specific path in a continuous, uniform, and stable manner. Common conveying mechanisms include belt conveyors, chain conveyors, roller conveyors, double-speed chain conveyors, and roller conveyors. The input mechanism 4 in the present disclosure can be any of these.

[0170] The input mechanism 4 transports the component 100 to be transferred close to the input portion of the lifting mechanism 2. When the component 100 to be transferred moves to partially contact the roller 221, it drives the roller 221 to rotate. The tangential component of the speed of the top of the roller 221 is consistent with the moving speed of the component 100 to be transferred. Therefore, after the component 100 to be transferred moves forward to completely separate from the input mechanism 4, the interaction between the roller 221 and the component 100 to be transferred is conducive to the continued forward movement of the component 100 to be transferred, thereby enabling the component 100 to be transferred to move forward to its proper position.

[0171] The input mechanism 4 gives the component to be transferred 100 an initial velocity, and the component to be transferred 100 can be moved into position under the interaction with the roller 221, eliminating the need for a pushing mechanism to push the component to be transferred 100 forward throughout the entire process, simplifying the structure of the elevator and saving costs. Moreover, because the pushing steps of the pushing mechanism are saved, the efficiency of the component to be transferred 100 entering is improved, thereby improving the transfer efficiency.

[0172] In some embodiments of the present disclosure, as shown in Figures 1 and 6, an output mechanism 5 is provided corresponding to each output position, and the output mechanism 5 has a conveying path extending along the second direction. The conveying path of the output mechanism 5 is arranged close to the output position corresponding to the output mechanism 5, and the pushing mechanism 3 corresponding to the output position can push the component 100 to be transferred located at the output position to the conveying path of the output mechanism 5 corresponding to the output position.

[0173] The output mechanism 5 is a conveying mechanism, which is a mechanical device that transports materials along a specific path in a continuous, uniform, and stable manner. Common conveying mechanisms include belt conveyors, chain conveyors, roller conveyors, double-speed chain conveyors, and roller conveyors. The output mechanism 5 in the present disclosure can be any of these.

[0174] The output mechanism 5 cooperates with the ejection mechanism 3 to output the component 100 to be transferred that has been lifted into position from the elevator, further improving the elevator's function of transferring the component 100 to be transferred.

[0175] In some embodiments of the present disclosure, as shown in Figures 5 and 6, a limiting rod 61 extending along the up and down directions is provided on at least one side of the accommodating space of the supporting assembly 22 along the second direction, and the limiting rod 61 is used to limit the position of the component to be transferred 100 accommodated in the accommodating space in the second direction.

[0176] The provision of the limiting rod 61 improves the stability of the component 100 to be transferred during the lifting process.

[0177] In some embodiments of the present disclosure, two limiting rods 61 are provided on the same side of the accommodating space of the carrying assembly 22 .

[0178] In this way, the stability of the component 100 to be transferred during the lifting process is further improved.

[0179] In some embodiments of the present disclosure, as shown in Figure 5, the limiting rod 61 is not provided on the side of the input part where the input mechanism 4 is provided, and the limiting rod 61 on the other side opposite to the input mechanism 4 extends to the side of the input part to form a stopping portion 611. When the component 100 to be transferred moves along the second direction until it abuts against the stopping portion 611, the component 100 to be transferred moves into place.

[0180] Since the component 100 to be transferred has a certain speed after entering the roller 221, the stopping position of the component 100 to be transferred is difficult to control. Therefore, the stopping portion 611 is used to stop the component 100 to improve the accuracy of the stopping position of the component 100 to be transferred.

[0181] In some embodiments of the present disclosure, the two limit rods 61 arranged on the same side of the accommodating space are extended to form a stopping portion 611, so that two stopping portions 611 are provided on the side of the input part. The two stopping portions 611 improve the stability of stopping the transfer component 100 and prevent it from skewing.

[0182] In some embodiments of the present disclosure, as shown in FIG6 , the limiting rod 61 is not provided on the side of the output part where the output mechanism 5 is provided, and the limiting rod 61 on the other side opposite to the output mechanism 5 extends to the side of the input part, and the portion of the limiting rod 61 extending to the side of the input part is used to limit the position of the part to be transferred 100 on that side.

[0183] In this way, the component to be transferred 100 raised to the output position will not be blocked when moving out and can be smoothly moved to the output mechanism 5 , and the side of the component to be transferred 100 facing away from the output mechanism 5 is limited by the limiting rod 61 .

[0184] In some embodiments of the present disclosure, limiting rods 61 are provided on both sides of the accommodating spaces at positions other than the input portion and the output portion of the carrying assembly 22 along the second direction.

[0185] In this way, the component to be transferred 100 is limited on all sides during the process of moving from the input position to the output position, thereby further improving the stability of the lifting and lowering of the component to be transferred 100.

[0186] In some embodiments of the present disclosure, the surface of the limiting rod 61 abutting against the to-be-transferred component 100 is configured as a convex arc-shaped surface.

[0187] During the process of lifting and lowering the component 100 to be transferred, the component 100 to be transferred will move relative to the limiting rod 61 . Providing the convex arc surface can prevent the limiting rod 61 from causing damage to the component 100 to be transferred.

[0188] In some embodiments of the present disclosure, the lifting machine further includes a frame 1 , and a lifting mechanism 2 , a pushing mechanism 3 , an input mechanism 4 and an output mechanism 5 are respectively installed on the frame 1 .

[0189] In this way, the lifting mechanism 2, the pushing mechanism 3, the input mechanism 4 and the output mechanism 5 are connected to form an integral device.

[0190] In the lifting mechanism 2, the first driving member 211 is installed on the frame 1, the first rotating shaft 21211 and the second rotating shaft 21221 are respectively rotatably connected to the frame 1 through bearings, the first mounting shaft and the second mounting shaft are fixedly connected to the frame 1, the first right-angle connector 21231 and the second right-angle connector 21233 are installed on the frame 1, and the connecting shaft 21232 is rotatably connected to the frame 1 through bearings.

[0191] In the ejection mechanism 3 , the ejection mounting seat 31 is mounted on the frame 1 .

[0192] The frame of the input mechanism 4 and the frame of the output mechanism 5 are respectively mounted on the frame 1 .

[0193] The limiting rod 61 is fixedly connected to the frame 1 .

[0194] In some embodiments of the present disclosure, four V-shaped rollers 223 are provided on the side of each mounting plate 222 facing away from the roller 221. The four V-shaped rollers 223 are distributed in two rows and two columns. The two V-shaped rollers 223 in the same column roll together with the same guide rod 62, and the guide rod 62 extends in the up and down directions.

[0195] The V-shaped roller 223 is a roller with a V-shaped concave surface on its outer circumference. Correspondingly, the guide rod 62 is a rod with a V-shaped convex surface on its outer surface.

[0196] The cooperation between the V-shaped roller 223 and the guide rod 62 further improves the smoothness of the movement of the bearing assembly 22, thereby improving the smoothness of the transfer of the component 100 to be transferred.

[0197] The guide rod 62 is fixedly connected to the frame 1 , which improves the stability of the guide rod 62 in guiding the V-shaped roller 223 .

[0198] It should be noted that, corresponding to each V-shaped roller 223, there are two guide rods 62 spaced apart in the first direction. One of the two guide rods 62 rolls with the V-shaped roller 223 during the rising process, and the other rolls with the V-shaped roller 223 during the descending process. In this way, the smoothness of the rising and descending process of the mounting plate 222 is improved.

[0199] FIG9 is a schematic structural diagram of a battery production line provided by some embodiments of the present disclosure.

[0200] An embodiment of the present disclosure also provides a battery production line, including a manufacturing machine 1000, a battery assembly device 2000 and the above-mentioned elevator, wherein the manufacturing machine 1000 is used to manufacture battery components; the battery assembly device 2000 is used to assemble batteries using battery components; wherein, at least one lifting mechanism 2 of the elevator lifts or lowers a solid pallet carrying battery components to transfer the solid pallet to the battery assembly device 2000, and at least one lifting mechanism 2 of the elevator lowers or lifts an empty pallet removed from the battery assembly device 2000 to transfer the empty pallet to the manufacturing machine 1000.

[0201] The battery assembly includes bare cells, and the manufacturing machine 1000 includes a winding machine for winding the bare cells.

[0202] The battery production line provided by the embodiment of the present disclosure includes the above-mentioned elevator. Since the structure of the elevator is simplified and the transfer efficiency of the elevator is improved, the structure of the battery production line provided by the embodiment of the present disclosure is simplified and the production efficiency of the battery is improved.

[0203] Figure 10 is a partial flow chart of the lifting method provided in some embodiments of the present disclosure; Figure 11 is a flow chart of the adding step provided in some embodiments of the present disclosure; Figure 12 is a specific method diagram of the lifting step when the lifting method provided in some embodiments of the present disclosure is applied to transfer battery components; Figure 13 is a flow chart of the lifting method provided in some embodiments of the present disclosure; Figure 14 is a flow chart of the discharging step provided in some embodiments of the present disclosure.

[0204] The embodiment of the present disclosure also provides a lifting method, which uses a hoist to lift multiple components 100 to be transferred and lower another multiple components 100 to be transferred. The hoist includes at least two lifting mechanisms 2, at least one lifting mechanism 2 is used to lift the components 100 to be transferred, and at least one lifting mechanism 2 is used to lower the components 100 to be transferred. The lifting operation and the lowering operation can be performed simultaneously; the lifting mechanism 2 includes a power component and a bearing component 22, the bearing component 22 is connected to the power component, the power component can drive the bearing component 22 to rise or fall, and the bearing component 22 includes multiple rollers 221, and the tops of the multiple rollers 221 are used to carry the components 100 to be transferred; by the rollers rotating in the same direction, the components 100 to be transferred can be moved in a direction perpendicular to the rotation axis of the roller 221 while contacting the top of the roller.

[0205] As shown in Figure 10, the improvement method includes:

[0206] S1, feeding step: feeding a component to be transferred onto the roller of the lifting mechanism for lifting, and feeding another component to be transferred onto the roller of the lifting mechanism for lowering;

[0207] S2, a lifting step: using a lifting mechanism for performing a lifting operation to lift the carried component to be transferred, and using a lifting mechanism for performing a lowering operation to lower the carried component to be transferred.

[0208] When the lifting method provided by the embodiment of the present disclosure is applied to transfer pallets in the battery production process, an empty pallet that does not carry bare cells is lifted or lowered by a lifting mechanism, and a full pallet that carries bare cells is lowered or lifted by another lifting mechanism, thereby realizing the transfer of pallets to achieve the transportation of bare cells. The lifting operation and the lowering operation can be carried out simultaneously, so that the operations of lifting and lowering the pallet are carried out simultaneously, realizing two-way transfer and high transfer efficiency.

[0209] When the pallet moves toward the roller 221 of the supporting assembly 22, the pallet itself has a certain initial velocity. When the pallet just contacts the roller 221, the rolling friction between the two will cause the roller 221 to start rotating. The rotation of the roller 221 can drive the pallet to continue moving forward, so that the pallet can maintain movement for a longer time, so that the pallet can be moved into place without the use of a pushing mechanism. Therefore, the pushing mechanism is eliminated, the structure of the elevator is simplified, and the time consumed by the pushing step of the pushing mechanism is also eliminated, so that the time for the pallet to enter the elevator is reduced, thereby improving the transfer efficiency of the elevator.

[0210] In some embodiments of the present disclosure, each lifting mechanism 2 has an input portion and an output portion spaced apart in the vertical direction, and an input mechanism 4 is provided corresponding to each input portion. The feeding step includes:

[0211] S11, step of placing the component to be transferred: placing the component to be transferred onto the input end of the input mechanism;

[0212] S12, conveying step: the input mechanism conveys the component to be transferred to the output end of the input mechanism;

[0213] S13, transfer step: the input mechanism transports the components to be transferred at its output end to the rollers of the carrying assembly.

[0214] In this way, the components 100 to be transferred are transported from outside the elevator into the accommodation space of the elevator through the input mechanism 4 , thereby improving the elevator's transfer function for the components 100 to be transferred.

[0215] In some embodiments of the present disclosure, the component 100 to be transferred includes an empty pallet without an object or a full pallet with an object, and the object includes a battery assembly;

[0216] S2, in a lifting step, a lifting mechanism for performing a lifting operation is used to lift the loaded pallet, and a lifting mechanism for performing a lowering operation is used to lower the loaded empty pallet;

[0217] Alternatively, the lifting mechanism for performing the lifting operation is used to lift the empty pallet being carried, and the lifting mechanism for performing the lowering operation is used to lower the full pallet being carried.

[0218] The lifting method provided in this embodiment is applied to the transportation of battery assemblies, which include bare cells and other components used to constitute battery cells. The structure of the elevator is simplified, which reduces the cost of transferring battery assemblies. The lifting method improves the transfer efficiency of battery assemblies, thereby improving the manufacturing cost and manufacturing efficiency of battery cells.

[0219] In some embodiments of the present disclosure, after the step of upgrading, the method further includes:

[0220] S3, discharging step: the lifting mechanism used for lifting operation pushes the lifted part to be transferred from the roller to the outside of the lifting mechanism, and the lifting mechanism used for lowering operation pushes the lowered part to be transferred from the roller to the outside of the lifting mechanism.

[0221] After the component 100 to be transferred is moved into position, it is moved out of the lifting mechanism 2 , which further improves the transfer function of the component 100 to be transferred by the elevator.

[0222] In some embodiments of the present disclosure, each lifting mechanism 2 has an input portion and an output portion spaced apart in the vertical direction, and a push-out mechanism 3 and an output mechanism 5 are provided corresponding to each output portion. The discharging step includes:

[0223] S31, a pushing step: when the carrier assembly moves to the output position, the power assembly stops driving, and the pushing mechanism pushes the components to be transferred in the accommodating space of the carrier assembly to the conveying path of the output mechanism;

[0224] S32, output step: the output mechanism transports the components to be transferred out of the lifting mechanism.

[0225] The output mechanism 5 cooperates with the ejection mechanism 3 to output the component 100 to be transferred that has been lifted into position from the elevator, further improving the elevator's function of transferring the component 100 to be transferred.

[0226] The above embodiments are intended only to illustrate the technical solutions of the present disclosure, and are not intended to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they may modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
