[0046] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0047] During the manufacturing process, the battery needs to go through a drying process, and the battery cells after being put into the shell are placed in a drying box for drying and dehydration. In order to improve the production efficiency of the battery, multiple drying boxes are usually arranged side by side in a straight line, and then a conveyor line is set up to transport the battery cells to the opening of the drying box, so as to achieve synchronous drying of multiple battery cells. However, this setting method requires a large site area, and each drying box needs to be equipped with a corresponding transfer device to facilitate the transfer of the battery cells on the conveyor line to the opening of the corresponding drying box, which will not only increase the equipment cost, but also affect the production efficiency.

[0048] In order to solve the above problems, the present application proposes a transfer device for drying equipment, the drying equipment includes a plurality of drying boxes arranged along the periphery of the transfer device, the transfer device includes: a support frame, a rotating assembly, a bearing assembly and a translation assembly, the support frame extends in a vertical direction; the rotating assembly is used to drive the support frame to rotate around a vertical center axis; the bearing assembly includes a bearing platform and a push-pull unit, the bearing platform is used to carry a target workpiece; the push-pull unit is used to drive the bearing platform and the target workpiece to enter and exit the drying box together along a first horizontal direction; the translation assembly is respectively connected to the support frame and the bearing assembly, and is used to drive the bearing assembly to move along a second horizontal direction to the entrance and exit of the drying box, the second direction intersecting with the first direction.

[0049] The transfer device of the present application can cooperate with multiple drying boxes at the same time to improve production efficiency, and has a small footprint and high space utilization.

[0050] The battery cells disclosed in the embodiments of the present application can be used in, but not limited to, electrical devices such as vehicles, ships or aircraft. The battery cells can be produced using the transfer device, drying equipment and battery production system disclosed in the present application, which is conducive to improving production efficiency and space utilization.

[0051] The embodiment of the present application provides an electric device using a battery as a power source, and the electric device may be, but is not limited to, a mobile phone, a tablet, a laptop, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, etc. Among them, the electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc., and the spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0052] The present application embodiment provides a transfer device 100 for a drying device, such as Figure 1-Figure 5 As shown, the transfer device 100 includes a support frame 110, a rotating assembly 120, a bearing assembly 130 and a translation assembly 140, the support frame 110 extends in the vertical direction; the rotating assembly 120 is used to drive the support frame 110 to rotate around the vertical center axis P; the bearing assembly 130 includes a bearing platform 131 and a push-pull unit 132, the bearing platform 131 is used to carry the target workpiece; the push-pull unit 132 is used to drive the bearing platform 131 and the target workpiece to enter and exit the drying box along a horizontal first direction X; the translation assembly 140 is respectively connected to the support frame 110 and the bearing assembly 130, and is used to drive the bearing assembly 130 to move along a horizontal second direction Y to the entrance and exit of the drying box, and the second direction Y intersects with the first direction X.

[0053] The drying equipment includes a plurality of drying boxes, which can be arranged around the periphery of the transfer device 100. The drying box has a vacuum drying chamber inside, which can perform vacuum drying on the target workpiece placed inside. The target workpiece can be a battery cell after the shell assembly is completed, and the type of the battery cell can be a battery cell of any material system, which is not limited in this application.

[0054] The support frame 110 is a support structure extending in the vertical direction, and may be a truss structure or a pipe frame structure, or a hollow tube structure. The present application does not impose any limitation on this, as long as the bearing strength requirements can be met.

[0055] The rotating assembly 120 may be any rotating drive assembly, which is connected to the support frame 110 to drive the support frame 110 to rotate around a specific central axis P. The position of the central axis P may be set as needed. In some embodiments, the projection of the central axis P on the horizontal plane may fall within the projection range of the support frame 110 on the horizontal plane, and the support frame 110 is driven to rotate; in other embodiments, the projection of the central axis P on the horizontal plane may be outside the projection range of the support frame 110 on the horizontal plane, and the support frame 110 revolves around the central axis P.

[0056] The bearing assembly 130 includes a bearing platform 131 and a push-pull unit 132. The bearing platform 131 may include a fixture for clamping multiple target workpieces. The number of fixtures may be one or more, and the fixtures may be set on a tray or a box structure. The push-pull unit 132 is a power unit that can output power to drive the bearing platform 131 to carry the target workpiece and move back and forth along the first direction X, so as to send the target workpiece into or out of the drying box. It can be understood that the first direction X is not fixed. In some examples, multiple drying boxes are arranged in a ring shape on the periphery of the transfer device 100. Corresponding to each drying box, the first direction X is perpendicular to the plane where the entrance and exit of the drying box are located. The push-pull unit 132 can use a magnetic push-pull component to drive the bearing platform 131 to move along the first direction X by magnetic means; a ball screw structure can also be used.

[0057] The translation assembly 140 drives the bearing assembly 130 to translate along the second direction Y. In some embodiments, the second direction Y may be perpendicular to the first direction X.

[0058] In some embodiments, the arrangement of the multiple drying boxes is not limited to a simple ring shape, but is divided into a number of drying box groups arranged along the periphery of the transfer device 100. Each drying box group may include two or even more drying boxes arranged side by side. Such an arrangement is not only conducive to improving space utilization and production efficiency, but also can simplify the arrangement of the door of the multiple drying boxes arranged side by side, that is, the door of each drying box group can be arranged side by side, and when opened, one of the door can be overlapped with the adjacent door. This not only saves layout space, but also makes the control accuracy of the door switch easier to control, and the arrangement is simpler without increasing costs. Any two adjacent drying boxes in the multiple drying boxes arranged in a ring will have a certain angle between them. The existence of this angle will make it difficult to arrange the door of the drying box, which is prone to mutual interference and affects the opening angle of the door. If it is translated, a ring slide rail needs to be set, which significantly increases the cost.

[0059] When loading or unloading materials, the transfer device 100 of the present application can first rotate the supporting component 130 to the front of the corresponding drying box group through the rotating component 120, and then drive the supporting component 130 to translate through the translation component 140, so that the supporting platform and the target workpiece can be sent into or moved out of any drying box in the drying box group.

[0060] The transfer device 100 of the present application can adapt to various forms of drying box arrangements, improve the efficiency and convenience of transfer, reduce the equipment footprint, and greatly improve space utilization.

[0061] According to some embodiments of the present application, Figure 6 and Figure 7 As shown, the rotating assembly 120 includes a rotating table 121, a first driving unit (not shown in the figure) and a first transmission unit 122. The rotating table 121 is fixedly connected to the bottom of the support frame 110; the first transmission unit 122 is respectively connected to the first driving unit and the rotating table 121, so that the first driving unit can drive the rotating table 121 to drive the support frame 110 to rotate together.

[0062] The rotating platform 121 is a structural member connected to the support frame 110 . The rotating platform 121 and the bottom of the support frame 110 can be connected by any connection method, such as welding, riveting or fastener connection.

[0063] The first driving unit may be a motor or other feasible driving elements, which is not limited in the present application. The first transmission unit 122 may be any feasible transmission component, such as a gear, a rack or a screw rod, a belt, and the like.

[0064] The rotating assembly 120 further includes a base 123, which can be placed or connected to the ground or other supporting surfaces. The first driving unit can be disposed on the base 123 and is in transmission connection with the first transmission unit 122. The top surface of the rotating platform 121 is connected to the support frame 110, and the bottom surface of the rotating platform 121 is connected to the first transmission unit 122, and the connection method can be bolt connection.

[0065] By providing a rotating table connected to the bottom of the support frame 110, the rotating assembly 120 can be arranged at the bottom of the support frame 110, which is more conducive to simplifying the drive arrangement structure and reducing the number of components and manufacturing costs.

[0066] According to some embodiments of the present application, the first transmission unit 122 includes a first gear (not shown in the figure) and a second gear 1221 that are meshed with each other; the first gear is fixedly connected to the rotating output shaft of the first driving unit, and the second gear 1221 is fixedly connected to the rotating table 121.

[0067] The first gear and the second gear may be mutually meshing cylindrical spur gears, the circumferential side surface of the second gear 1221 is formed with meshing teeth, and the end surface is provided with a plurality of mounting holes for connecting with the bottom surface of the rotating table 121. The first driving unit may be a motor, and the first gear may be fixed to the output shaft of the first driving unit by key connection.

[0068] The gear connection has a relatively accurate rotational precision, which is beneficial to improving the precision control of loading or unloading of the transfer device. In addition, the gear structure has a strong axial bearing capacity, which can better support the upper support frame 110 and improve the stability and reliability of the structure.

[0069] According to some embodiments of the present application, Figure 8 As shown, the translation assembly 140 includes a first connecting member 141, a second connecting member 142 and a linear module 143; the first connecting member 141 is connected to the support frame 110; the second connecting member 142 is connected to the bearing assembly 130; the linear module 143 is used to drive the second connecting member 142 and the bearing assembly 130 to move along the second direction Y together.

[0070] The first connecting member 141 is disposed on a side surface of the translation assembly 140 facing away from the bearing assembly 130 . The first connecting member 141 may be connected to the support frame 110 in a fixed or detachable manner.

[0071] The linear module 143 is a transmission device for realizing linear motion. It is composed of a series of interconnected transmission parts, which are driven by a motor or other power source to realize precise linear motion. The linear module 143 may include a drive motor and a transmission unit connected to the drive motor, which can convert the rotational motion of the drive motor into linear motion, such as a ball screw, bevel gear transmission, etc. The second connecting member 142 may be a slider moving along a linear guide rail, and the slider translates along the second direction Y together with the bearing assembly 130.

[0072] In some embodiments, the travel length of the bearing assembly 130 along the second direction Y is at least greater than the sum of the widths of the two drying boxes, so that the bearing assembly 130 can be moved to the entrance or exit of any drying box by the translation assembly 140 .

[0073] By providing a translation module with a linear module, the translation of the carrying assembly 130 along the second direction Y can be achieved simply and at low cost, thereby improving the flexibility and scope of application of transportation.

[0074] According to some embodiments of the present application, Fig. 9 As shown, the translation assembly 140 also includes an angle adjustment member 144, and the first connecting member 1441 is connected to the support frame 110 through the angle adjustment member 144, and the angle adjustment member 144 is used to adjust the installation angle between the first connecting member 141 and the support frame 110 along the horizontal direction.

[0075] The angle adjustment member 144 may include one or more adjustable components, which can adjust the horizontal installation angle between the translation assembly 140 and the support frame 110, thereby adjusting the orientation of the second direction Y. In this way, the angle adjustment member 144 can perform secondary adjustment when the rotation accuracy is insufficient.

[0076] In some embodiments, the angle adjustment member 144 includes at least two connecting cylinders, which can adjust the installation distance between the translation assembly 140 and the support frame 110 by extending and retracting the cylinder shaft, so that the multiple connecting cylinders arranged along the second direction Y can adjust the horizontal installation angle between the translation assembly 140 and the support frame 110 by controlling the extension amount of the cylinder shaft. It can be understood that the above-mentioned connecting cylinders are only an example of a specific implementation of the angle adjustment member, and should not be understood as a specific limitation on the angle adjustment member 144 of the present application, and the present application does not limit other feasible angle adjustment components.

[0077] The angle adjustment member 144 can be provided to supplement the rotation accuracy of the rotating assembly 120, thereby improving the movement accuracy of the rotating feeding of the transfer device 100, thereby achieving more accurate and efficient entry and exit of dry materials and improving production efficiency.

[0078] According to some embodiments of the present application, Figure 3 As shown, the transfer device 100 further includes a lifting assembly 150, which is connected to the bearing assembly 130 and the support frame 110 respectively, and is used to drive the bearing assembly 130 to rise and fall in a vertical direction.

[0079] The lifting assembly 150 is a component for adjusting the height of the load-bearing assembly. In some examples, the lifting assembly 150 may not be directly connected to the load-bearing assembly 130, but may be indirectly connected to the load-bearing assembly 130 by connecting to the translation assembly 140, and then the height position of the load-bearing assembly 130 may be adjusted by the translation assembly 140.

[0080] Combined with the lifting component, the transfer device 100 can realize the movement of the bearing component along the horizontal first direction X, the horizontal second direction Y and the vertical direction, thereby increasing the flexibility of the transfer action, better adapting to drying boxes with different layout forms, and improving work efficiency.

[0081] According to some embodiments of the present application, Figure 3 As shown, the lifting assembly 150 includes a second driving unit 151 and a second transmission unit 152. The second driving unit 151 is connected to the support frame 110; the second transmission unit 152 is respectively connected to the second driving unit 151 and the bearing assembly 130, and the second transmission unit 152 includes one or more of a transmission belt, a transmission gear, a transmission rack and a ball screw.

[0082] The second driving unit 151 may be a driving motor, and the second transmission unit 152 may include a conveyor belt and a conveyor roller fixed to the support frame 110. In some embodiments, one end of the conveyor belt is connected to the output shaft of the second driving unit 151, and the other end of the conveyor belt bypasses the conveyor roller and is connected to the bearing assembly 130 or the translation assembly 140. In other embodiments, the conveyor belt bypasses the conveyor roller and both ends are connected to the bearing assembly 130 or the translation assembly 140, and the second driving unit 151 drives the conveyor belt to realize the lifting and lowering of the bearing assembly 130.

[0083] It is understandable that the second transmission unit 152 can also be any structure that can achieve the purpose of lifting, such as a transmission gear, a transmission rack or a ball screw.
