[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Specific examples are given below.

[0019] See also Figure 1 to Figure 3 , a dust collecting device for a battery cell after rolling grooves, comprising a mounting frame 1, a fixed tube 2, a movable tube 3, a dust hood 4, a dust box 5, a connecting tube 6, a bracket 7, a dust bag 8 and a vortex fan 9, a fixed tube 2 is mounted on the L-shaped mounting frame 1, a movable tube 3 is slidably mounted inside the fixed tube 2, a dust hood 4 is mounted at the bottom end of the movable tube 3, a mounting plate 11 is mounted on the outer side of the bottom end of the fixed tube 2, a pneumatic cylinder 10 is mounted on the mounting plate 11, a cover plate 12 is mounted on the outer side of the top end of the movable tube 3, and the cover plate 12 is connected to the telescopic end of the pneumatic cylinder 10, and the cover plate 12 is driven to rise and fall by the operation of the pneumatic cylinder 10, so as to realize the lifting and lowering adjustment of the movable tube 3 and the dust hood 4, and adjust the relative position of the dust hood 4 and the battery cell;

[0020] A dust box 5 is installed on the mounting frame 1, and the dust box 5 is connected to the fixed pipe 2 through a connecting pipe 6. A bracket 7 is installed inside the dust box 5, and a dust bag 8 is installed on the bracket 7. A vortex fan 9 is installed on the outside of the dust box 5.
