With the continuous expansion of the application field of power battery, the demand of its market is also increasing.

[0052] The battery needs to go through a drying process in the manufacturing process. The bare battery cell is placed in the drying box for drying and water removal. In order to improve the production efficiency of the battery, a plurality of drying boxes are arranged in a straight line side by side, and a conveying line is arranged to convey the battery monomer to the opening of the drying box, so as to realize the synchronous drying of a plurality of battery monomers. But this kind of setting method needs to occupy a large area, and each drying box needs to be provided with a corresponding transfer device, so as to transfer the battery monomer on the conveying line to the opening of the corresponding drying box, which not only increases the cost of equipment, but also affects the production efficiency.

[0053] To address the above problems, this application proposes a drying device comprising a transfer device and several drying chamber assemblies. The transfer device includes a support component and a rotating component. The support component includes a support platform for supporting a target workpiece and a push-pull component for driving the target workpiece to move. The rotating component drives the support component to rotate. Several drying chamber assemblies are arranged along the outer periphery of the transfer device. At least one drying chamber assembly includes several drying chambers arranged side-by-side along a horizontal straight direction. The transfer device is configured to feed or remove the target workpiece into or out of the drying chambers via the rotating component and the push-pull component. The drying chamber assemblies of this application, arranged along the outer periphery of the transfer device, occupy a small area and have high space utilization. The side-by-side arrangement of several drying chambers along a horizontal direction within the drying chamber assembly simplifies the structural layout of the chamber door panels.

[0054] The battery cells disclosed in this application can be used, but are not limited to, in electrical devices such as vehicles, ships, or aircraft. Battery cells can be produced using the transfer components, drying equipment, and battery production system disclosed in this application, which helps improve production efficiency and space utilization.

[0055] This application provides a drying device 1000, such as... Figures 1-2 As shown, the drying equipment 1000 includes a transfer device 100 and a plurality of drying chamber groups 200. The transfer device 100 includes a carrying component 130 and a rotating component 120. The carrying component 130 includes a carrying platform 131 for carrying the target workpiece and a push-pull component 132 for driving the target workpiece to move. The rotating component 120 is used to drive the carrying component 130 to rotate. The plurality of drying chamber groups 200 are arranged along the outer periphery of the transfer device 100. At least one drying chamber group 200 includes a plurality of drying chambers arranged side by side along a horizontal straight direction. The transfer device 100 is configured to send the target workpiece into or out of the drying chamber 210 by means of the rotating component 120 and the push-pull component 132.

[0056] The carrying assembly 130 includes a carrying table 131 and a push-pull unit 132. The carrying table 131 can include clamps for clamping a plurality of target workpieces. The number of clamps can be one or more. The clamps can be arranged on a tray or a box structure. In some embodiments, the carrying table 131 can be driven by the push-pull unit 132 to enter or exit the drying box 210 together with the target workpieces. In other embodiments, the carrying table 131 includes a fixed support structure, and clamps movably arranged on the support structure. The clamps are used to clamp the target workpieces and move into or out of the drying box 210 together with the target workpieces under the action of the push-pull unit 132. The push-pull unit 132 is a power unit that can output power to drive the target workpieces to move back and forth along the first direction X, so as to send the target workpieces into or out of the drying box 210. It can be understood that the first direction X is not fixed and in some examples, the first direction X is perpendicular to the plane in which the entrance and exit of each drying box are located. The push-pull unit 132 can use a magnetic push-pull member to drive the carrying table 131 to move along the first direction X by magnetic force, or use a ball screw structure.

[0057] The rotating assembly 120 can be any power structure capable of driving the carrying assembly 130 to rotate.

[0058] The plurality of drying box groups 200 are arranged in a ring around the outer periphery of the transfer device 100. The transfer device 100 can rotate so that the transfer device 100 can be rotated to the front of the entrance and exit of any drying box group 200. In this way, the rotating assembly 120 of the transfer device 100 can move the carrying table 131 with the target workpieces to the opening of any drying box 210, and then the push-pull unit 132 can move the plurality of target workpieces on the carrying table 131 into or out of the drying box 210.

[0059] The plurality of drying boxes 210 can be of the same size. In some examples, each drying box group 200 includes an equal number of drying boxes 210. The drying box 210 has a vacuum drying cavity inside and can perform vacuum drying on the target workpieces placed inside. The target workpieces can be battery cells after being assembled into a shell. The battery cells can be of any material system, which is not limited in the present application.

[0060] The drying box group is arranged to include a plurality of drying boxes arranged side by side. This can increase the number of drying boxes around the outer periphery of the transfer device 100, improve space utilization, and improve production efficiency. In addition, the side-by-side arrangement of the plurality of drying boxes can simplify the arrangement of the box door plate, making the overall structure more compact and further reducing the floor area.

[0061] According to some embodiments of the present application, as shown inFigure 2 As shown, the at least one drying box group 200 further comprises a box door 220, which comprises a plurality of box door panels corresponding to the plurality of drying box bodies 210, and the box door panels are configured to cover the entrances of the drying box bodies 210; any box door panel can overlap with other box door panels in the thickness direction of the box door panel.

[0062] As shown, the drying box group 200 comprises two drying box bodies 210, and the box door 220 comprises a first box door panel 221 and a second box door panel 222 respectively arranged corresponding to the two drying box bodies 210. Since the two drying box bodies 210 are arranged side by side along the horizontal straight line direction, the first box door panel 221 and the second box door panel 222 are also arranged parallel to the entrances of the drying box bodies 210, so that one of the first box door panel 221 and the second box door panel 222 can be moved to overlap with the other. Figure 2

[0063] It can be understood that one of the first box door panel 221 and the second box door panel 222 can overlap with the other by translation or flipping. When the number of box door panels exceeds two, the plurality of box door panels can also partially or completely overlap by translation, flipping or other similar motion.

[0064] The arrangement of the box door panels of the embodiments of the present application is simple, and the plurality of box door panels do not interfere with each other, while maintaining sufficient opening angle, thereby improving space utilization and production efficiency.

[0065] According to some embodiments of the present application, in some embodiments, the plurality of drying box bodies 210 are each provided with a plurality of drying cavities in the height direction.

[0066] Any drying box body 210 can comprise a plurality of drying cavities stacked in the height direction, and each drying cavity can be independently controlled or controlled by a unified control unit. In some embodiments, the drying box body 210 can also be composed of a plurality of sub-boxes stacked in the height direction, and each sub-box is an independent component and has one drying cavity.

[0067] Providing a plurality of drying cavities in the height direction can further improve space utilization, reduce floor area, improve the processing capacity of target workpieces, and thus improve production efficiency.

[0068] ​According to some embodiments of the present application, the transfer device 100 further comprises a support frame 110 configured to be driven by the rotating assembly 120 and rotate around a vertical central axis P, and a translation assembly 140 connected with the support frame 110 and the carrying assembly 130 respectively, the translation assembly 140 and the carrying assembly 130 are configured to rotate synchronously with the support frame 110, the push-pull unit 132 is used to drive the target workpiece to enter and exit the drying box 210 along the horizontal first direction X, and the translation assembly 140 is used to drive the carrying assembly 130 to move between the box openings of a plurality of drying boxes 210 in the drying box group 200 along the horizontal second direction Y intersecting with the first direction X. It can be understood that the second direction Y is also not fixed and can change as the translation assembly 140 rotates with the support frame 110.

[0069] The support frame 110 is a support structure extending in the vertical direction, which can be a truss structure or a pipe frame structure, and can also be a hollow pipe structure, which is not limited in the present application as long as the bearing strength requirement is met.

[0070] The rotating assembly 120 is connected with 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 can be set as needed. In some embodiments, the projection of the central axis P on the horizontal plane can fall within the projection range of the support frame 110 on the horizontal plane, at this time the support frame 110 is driven to rotate; in other embodiments, the projection of the central axis P on the horizontal plane can be located outside the projection range of the support frame 110 on the horizontal plane, at this time the support frame 110 revolves around the central axis P.

[0071] The translation assembly 140 drives the carrying assembly 130 to translate along the second direction Y, which can be parallel to the arrangement direction of the plurality of drying boxes 210. In some embodiments, the second direction Y can be perpendicular to the first direction X.

[0072] In some embodiments, each drying box group 200 can include two or more drying boxes 210 arranged side by side. Such an arrangement not only helps to improve space utilization and production efficiency, but also simplifies the arrangement of the doors of the plurality of drying boxes 210 arranged side by side, i.e. the doors of each drying box group 210 can be arranged side by side, and when opened, one of the doors can overlap with the adjacent door, which not only saves arrangement space, but also makes it easier to control the opening and closing precision of the door. In comparison, any two adjacent drying boxes in a ring-shaped arrangement will have a certain included angle, which will make it difficult to arrange the doors of the drying boxes and will easily interfere with the opening angle of the doors. If translation is required, a ring-shaped slide rail needs to be provided, which significantly increases the cost.

[0073] The transfer device 100 of the present application can rotate the carrying assembly 130 to the front of any drying box group 200 through the rotating assembly 120 when loading or unloading, and then drive the carrying assembly 130 to translate by the translating assembly 140, so that the target workpiece on the carrying table 131 can be moved to the front of the box opening of any drying box body 210 in the drying box group 200, and then the target workpiece can be sent into or out of the drying box body 210 by the push-pull assembly 132.

[0074] The transfer device 100 of the present application can drive the carrying assembly 130 to rotate and translate, which can adapt to various forms of drying box body arrangement, improve the efficiency and convenience of transfer, reduce the equipment floor area, and improve the space utilization; in particular, the translating assembly 140 driving the carrying assembly 130 to translate along the second direction can be adapted to several drying box bodies 210 arranged side by side, which can realize efficient entry and exit of the target workpiece into the drying box body, and is beneficial to simplify the setting of the box door and improve the production efficiency.

[0075] According to some embodiments of the present application, as shown in Figure 6 and Figure 7 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 with the bottom of the support frame 110; the first transmission unit is respectively in transmission connection with the first driving unit 122 and the rotating table 121, so that the first driving unit can drive the rotating table 121 to rotate the support frame 110 together.

[0076] The rotating table 121 is a structural member connected with the support frame 110, and the rotating table 121 and the bottom of the support frame 110 can be connected by any connection method, such as welding, riveting or fastener connection.

[0077] The first driving unit can be a motor or other feasible driving element, and the present application does not limit this. The first transmission unit 122 can be any feasible transmission assembly, such as gear, rack or screw, belt, etc.

[0078] The rotating assembly 120 further includes a base 123, which can be placed or connected to the ground or other supporting surface. The first driving unit can be arranged on the base 123 and in transmission connection with the first transmission unit 122. The top surface of the rotating table 121 is connected with the support frame 110, and the bottom surface of the rotating table 121 is connected with the first transmission unit 122, and the connection method can be bolt connection.

[0079] By arranging the rotating table connected with the bottom of the support frame 110, the rotating assembly 120 can be arranged at the bottom of the support frame, which is more conducive to simplifying the driving arrangement structure and reducing the number of components and manufacturing cost.

[0080] According to some embodiments of the present application, the first transmission unit 122 comprises a first gear (not shown in the figure) and a second gear 1221 which are engaged with each other; the first gear is fixedly connected with the rotating output shaft of the first driving unit, and the second gear 1221 is fixedly connected with the rotating table 121.

[0081] The first gear and the second gear can be cylindrical spur gears which are engaged with each other, the circumferential side surface of the second gear 1221 is formed with engagement 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 can be a motor, and the first gear can be fixed on the output shaft of the first driving unit by means of key connection.

[0082] The gear connection has relatively accurate rotation precision, which is conducive to improving the precision control of the feeding or discharging of the transfer device, and the gear structure has relatively strong axial bearing capacity, which can better support the support frame 110 above, thereby improving the stability and reliability of the structure.

[0083] According to some embodiments of the present application, as shown in Figure 10 The translation assembly 140 comprises a first connecting piece 141, a second connecting piece 142 and a linear module 143; the first connecting piece 141 is connected with the support frame 110; the second connecting piece 142 is connected with the bearing assembly 130; and the linear module 143 is used to drive the second connecting piece 142 and the bearing assembly 130 to move together along the second direction Y.

[0084] The first connecting piece 141 is arranged on the side surface of the translation assembly 140 which faces away from the bearing assembly 130, and the first connecting piece 141 can be connected with the support frame 110 in a fixed or detachable manner.

[0085] The linear module 143 is a kind of transmission device used to realize linear motion. It is composed of a series of transmission components connected with each other, and is driven by a motor or other power source to realize precise linear motion.

[0086] In some embodiments, the stroke length of the bearing assembly 130 along the second direction Y is at least greater than the width of two drying box bodies, so that the bearing assembly 130 can be moved to the entrance and exit of any one of the drying box bodies under the action of the translation assembly 140.

[0087] By setting the translation module with the linear module, the translation of the bearing assembly 130 along the second direction Y can be simply and low-costly realized, thereby improving the flexibility and application range of the transfer.

In this way, the angle adjusting member 144 can perform secondary adjustment in the case of insufficient rotation accuracy.

[0090] In some embodiments, the angle adjusting member 144 comprises at least two connecting cylinders. The connecting cylinders can adjust the installation distance between the translation assembly 140 and the support frame 110 by the extension and retraction of the cylinder shafts. In this way, 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 shafts. It can be understood that the above connecting cylinders are only an example of a specific implementation of the angle adjusting member, and should not be understood as a specific limitation of the angle adjusting member 144 of the present application. The present application does not limit other feasible angle adjusting members.

[0091] By setting the angle adjusting member 144, the rotation accuracy of the rotation assembly 120 can be supplemented, so as to improve the movement accuracy of the rotation feeding of the transfer device 100, so as to more accurately and efficiently realize the feeding and discharging of the dry materials, and improve the production efficiency.

[0094] In combination with the function of the lifting assembly, the transfer device 100 can realize the movement of the bearing assembly in the horizontal first direction X, the horizontal second direction Y and the vertical direction, so as to increase the flexibility of the transfer movement, better adapt to the dry box body arranged in different forms, and improve the operation efficiency.
