The upper tube device 4 is used to receive an external rubber tube provided by the rubber tube feeding device 3 and sleuth the rubber tube on the battery body a. The sealing device 5 seals the rubber tube sleeved on the battery body a. The feeding device 6 transfers the battery body a with a casing to the next station.

[0046] Specifically, in this embodiment, several clamping seats are installed on the turntable 1 in a circular array structure. One clamping seat clamps the lead part of a battery body a. Under the rotation of the turntable 1, the battery body a first rotates to the working station of the pretreatment device 2. The pretreatment device 2 cleans, inspects, and dries the battery body a. Synchronously, the hose feeding device 3 supplies a hose with a preset length from the outside to the tube mounting device 4. When the pretreated battery body a rotates to the working station of the tube mounting device 4, the tube mounting device 4 sleeves the outside hose on the battery body a to complete the tube sleeving process of the battery body a. Then, the battery body a with the hose sleeved on it rotates to the sealing device 5 working station. The sealing device 5 seals the hose so that the hose tightly wraps around the battery body a to form an integrated unit to complete the tube sleeving process. Finally, when it rotates to the blanking device 6, the blanking device 6 transports the battery body a after tube sleeving to the next process.

[0047] By sequentially installing the pretreatment device 2, the hose feeding device 3, the tube mounting device 4, the sealing device 5, and the blanking device 6 around the turntable 1, and the turntable 1 is provided with several clamping seats.
