For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0034] See attached Figure 1 As shown, a lifting mechanism in this embodiment is arranged in a double-layer tunnel furnace, and is used to transport battery cells entering the double-layer tunnel furnace. The lifting mechanism can be lifted in the vertical direction to transport the workpiece to the drying layer of the upper furnace body and the lower furnace body for drying. In this embodiment, the workpiece is a battery cell, and the battery cell is placed in a flower basket 6. The lifting mechanism transports the battery cell by transporting the flower basket 6.

[0035] In some embodiments, the lifting mechanism includes a lifting assembly 1 and a fixing assembly 2. The lifting assembly 1 includes a first driving member 11. The first driving member 11 is fixedly connected to the frame of the double-layer tunnel furnace, and the frame fixes and supports the first driving member 11. The first driving member 11 and the fixing assembly 2 are connected through a guide rod 12 and a telescopic rod of the first driving member 11. The fixing assembly 2 can move in the vertical direction along the guide rod 12, thereby transporting the battery cells in the fixing cavity 24 to the drying layers of the upper furnace body and the lower furnace body. The first driving member 11 is a cylinder or an electric cylinder.

[0036] See attached Figure 2-4As shown, in some embodiments, the fixing assembly 2 includes an upper fixing plate 21 and a lower fixing plate 22 arranged in parallel, and a side fixing plate 23 arranged in parallel, and the four fixing plates are connected in sequence to form a fixing cavity 24. The transmission assembly 3 is arranged in the fixing cavity 24 to transmit the battery cells contained in the basket 6.

[0037] In some embodiments, the transmission assembly 3 includes a second driving member 31 disposed below the lower fixed plate 22 and fixedly connected to the lower fixed plate 22, and also includes a transmission belt 32, a transmission rod 33 and a rotating roller 34. The second driving member 31 is connected to the transmission rod 33 through the transmission belt 32, and the transmission rod 33 is driven to rotate by the transmission belt 32. Rotating rollers 34 are provided at both ends of the transmission rod 33, and the rotating rollers 34 rotate synchronously with the rotation of the transmission rod 33. A synchronous belt 35 is sleeved on the rotating roller 34, and the synchronous belt 35 is driven to rotate during the rotation of the rotating roller 34, thereby transmitting the flower basket 6 located on the synchronous belt 35. The second driving member 31 is a driving motor.

[0038] See attached Figure 2 , 5 6, in some embodiments, a limiting structure 4 is also included, which includes a guide bar 41 arranged on the side of the synchronous belt 35 away from the flower basket 6. The guide bar 41 is provided with a guide surface 411 at the feeding end, and the guide surface 411 is inclined. The vertical height of the guide bar 41 is higher than the height of the synchronous belt 35. When the flower basket 6 enters the fixed cavity 24, if the position of the flower basket 6 deviates to the left or right, the flower basket 6 will be corrected along the guide surface 411 so that the flower basket 6 can be in the set transport position. Then the flower basket 6 moves along the guide bar 41. Through the setting of the guide bar 41, the positions of the left and right sides of the flower basket 6 are corrected / limited.

[0039] In some embodiments, the guide bar 41 is connected to the lower fixed plate 22 through a guide support frame 412, and a strip groove 413 perpendicular to the transportation direction of the flower basket 6 is set on the guide support frame 412. The guide bar 41 is detachably connected to the guide support frame 412 through the strip groove 413. By changing the connection position of the guide bar 41 and the strip groove 413, the distance between the guide bar 41 and the synchronous belt 35 can be changed, so that the transmission mechanism can adapt to flower baskets 6 of different widths, thereby improving the adaptability of the lifting structure.

[0040] See attached Figure 2 and attached Figure 3 As shown, in some embodiments, the limiting structure 4 also includes a blocking cylinder 42, which is connected to the lower fixed plate 22, and the blocking cylinder 42 is arranged at one end of the fixed cavity 24 close to the discharge end. When a flower basket enters the fixed cavity 24, the blocking cylinder 42 drives the telescopic shaft to move upward, and the telescopic shaft can prevent the flower basket 6 from continuing to move toward the discharge end, thereby limiting the position of the flower basket 6 at the discharge end.

[0041] In some embodiments, a plurality of blocking cylinders 42 are provided, arranged in a direction perpendicular to the transport direction. Preferably, two blocking cylinders 42 are provided for each flower basket 6, and the positions of the two blocking cylinders 42 are as far apart as possible, so as to improve the blocking accuracy of the blocking cylinders 42 on the flower basket 6.

[0042] See attached Figures 5 to 7 As shown, in some embodiments, the limiting structure 4 further includes a pressing component 43, which is connected to the lower surface of the upper fixing plate 21 and is located directly above the synchronous belt 35. The pressing component 43 is used to apply a downward force to the flower basket 6, so that the pressing component 43 and the synchronous belt 35 clamp the flower basket 6, thereby fixing the position of the flower basket to prevent the flower basket from shifting during the lifting process.

[0043] In some embodiments, the compression assembly 43 includes a compression cylinder 431 and a compression piece 433. The compression cylinder 431 is fixedly connected to the lower surface of the upper fixed plate 21. The compression cylinder 431 is connected to the compression piece 433 through the telescopic rod 432 of the cylinder. The compression cylinder 431 can drive the compression piece 433 toward the direction of the synchronous belt 35, thereby clamping the flower basket 6.

[0044] In some embodiments, a limiting groove 434 is provided on the side of the pressing member 433 close to the flower basket 6. During the downward movement of the pressing member 433, a partial area of ​​the end plate 61 of the flower basket 6 can be accommodated in the limiting groove. The end plate 61 is limited by the limiting groove, and then the flower basket 6 is limited, which can prevent the flower basket 6 from shaking left and right, thereby enhancing the stability of the battery cell.

[0045] In some embodiments, the limiting groove 434 is provided with a flared opening 435 on one side close to the end plate 61, and the horizontal width of the flared opening 435 is greater than the horizontal width of the limiting groove 434. When the end plate 61 enters the limiting groove 434, the flared opening 435 plays a guiding role, so that the flower basket can enter the limiting groove 434 along the flared opening, and then the position of the flower basket is corrected to ensure that the flower basket is located at the preset position.

[0046] In some embodiments, sensors 5 are also included. Multiple sensors 5 are provided, which are respectively located at the feed end and the discharge end and at the left and right sides of the flower basket 6. The sensor 5 located at the feed end can sense whether the flower basket has entered the fixed cavity 24, and the sensor 5 located at the discharge end is used to sense whether the position of the flower basket entering the fixed cavity 24 is accurate. By providing sensors 5 at both the feed end and the discharge end, the position of the flower basket 6 entering the fixed cavity 24 is sensed and detected, so as to determine whether the position of the flower basket 6 is accurate.
