[0042] After the battery is assembled, moisture may exist inside the battery, and the battery needs to be dried to improve the stability of the battery. The battery conveying device is used to convey the battery from the upstream process to the drying process. After the battery conveying device conveys the battery to the specified position, the mechanical hand grabs the battery and transfers the battery to the drying device for drying.

[0043] To solve the above technical problems, the embodiments of the present application provide a battery conveying device. The battery conveying device comprises a conveying module, a plurality of trays and a transmission module. The conveying module comprises a stator assembly and a plurality of movers. The plurality of trays are connected to the plurality of movers in a one-to-one correspondence. The trays are configured to support the batteries. The stator assembly comprises a mounting bracket, a conveying platform, a plurality of conveying stators, a return platform and a plurality of return stators. The conveying platform and the return platform are connected to the mounting bracket. The plurality of conveying stators are connected to the conveying platform. The arrangement direction of the plurality of conveying stators is the same as the conveying direction of the battery. The mover and the conveying stator can be connected by magnetic force. The plurality of return stators are connected to the return platform. The arrangement direction of the plurality of return stators is the same as the conveying direction. The mover and the return stator can be connected by magnetic force. The transmission module is configured to move the mover connected to the conveying stator to the return stator, and move the mover connected to the return stator to the conveying stator. Since the mover is driven by magnetic force, the moving speed of the mover and the distance between the adjacent two movers can be controlled by controlling the size of the magnetic force. After the battery reaches the specified position, the arrangement mode of the battery can be controlled by magnetic force, so that the battery is arranged according to the number and spacing required by the mechanical hand to grab. That is, the grouping of the battery can be directly realized by the battery conveying device, without additional grouping of the battery, reducing the process and improving the drying efficiency.

[0045] The embodiments of the present application provide a battery conveying device. FIG. 1 is a simple front view of the battery conveying device according to some embodiments of the present application. Referring to FIG. 1, the battery conveying device comprises a conveying module 10, a plurality of trays 20 and a transmission module 30.

Since the stator assembly 11 is connected with the mover 12 through magnetic force, the stator assembly 11 and the mover 12 are not in contact, and the friction between the stator assembly 11 and the mover 12 is small during the movement of the mover 12, the energy consumption of the battery conveying device is low, and the cost can be reduced.

The conveying direction X is not limited to be a straight line, when the battery is conveyed along a straight line, the conveying direction X is a straight line, and when the battery is conveyed along a curve, the conveying direction X is a curve.

[0050] In the embodiment of the present application, the tray 20 is connected with the mover 12 one by one, that is, one tray 20 is connected with one mover 12, and one mover 12 is connected with only one tray 20. The tray 20 can be used to support the battery, and when the mover 12 slides on the stator assembly 11 along the conveying direction X, the mover 12 drives the battery supported on the tray 20 to move, thereby conveying the battery.

[0051] In the embodiment of the present application, the tray 20 and the mover 12 can be connected in a detachable manner, or the tray 20 and the mover 12 can be connected in a non-detachable manner.

[0052] In the embodiment of the present application, the mounting bracket 111 provides support for the entire stator assembly 11, and the form of the mounting bracket 111 is not limited, for example, the mounting bracket 111 can be in the form of a frame.

When the mover 12 moves on the conveying stator 113, the conveying stator 113 is stationary.

[0055] In the embodiment of the present application, the mounting bracket 111 provides support for the conveying platform 112, and the conveying platform 112 defines the arrangement direction of the conveying stator 113 and provides support for the conveying stator 113. The conveying stator 113 is a component magnetically connected with the mover 12. This structure is more compact and can simplify the structure of the entire battery conveying device.

[0056] In the embodiment of the present application, the return platform 114 is consistent with the conveying platform 112 in structure, and the return stator 115 is consistent with the conveying stator 113 in structure. The mover 12 can also move along the arrangement direction of the return stator 115. When the mover 12 moves on the return stator 115, the return stator 115 is stationary.

[0058] In the embodiment of the present application, the transmission module 30 is provided for transmitting the mover 12, so that the conveying stator 113 and the mover 12 realize conveying the tray 20 and the battery 200, and the return stator 115 and the mover 12 realize recycling the tray 20, so that the tray 20 can receive the battery 200 again. The battery conveying device can realize continuous conveying of the battery 200, and can convey more batteries 200, with higher conveying efficiency.

[0059] In the embodiment of the present application, the battery is placed on the tray 20, and the conveying of the battery is realized by controlling the mover 12 to slide on the stator assembly 11 along the conveying direction X. Since the stator assembly 11 and the mover 12 are connected by magnetic force, i.e., the mover 12 is driven by magnetic force, the moving speed of the mover 12 and the distance between adjacent two movers 12 can be controlled by controlling the size of the magnetic force.
