[0029] A dust handling mechanism and a pre-folding tab device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0030] Reference Figure 1 The utility model aims to provide an embodiment of a dust handling mechanism and a pre-folded tab device.

[0031] In this embodiment, a pre-folding tab device mainly includes a pre-folding mechanism and a dust handling mechanism.

[0032] In some embodiments of the present invention, the pre-folding mechanism includes a first rolling wheel 200 and a second rolling wheel 210 that are arranged relatively to each other, a rolling portion is provided between the first rolling wheel 200 and the second rolling wheel 210, the rolling portion is used to roll the pole piece 120, and a dust removal channel 110 is arranged at the discharge end of the first rolling wheel 200 and the second rolling wheel 210.

[0033] The first rolling wheel 200 and the second rolling wheel 210 roll relative to each other, so that the rolling part rolls the pole piece 120, and the pole piece 120 forms a pole ear. Since the pole piece 120 undergoes physical deformation, more dust is easily generated at the pole ear position. Therefore, after the pole piece 120 completes the pre-folding pole ear processing, it can enter the dust removal channel 110 for dust removal.

[0034] A dust handling mechanism according to an embodiment of the present invention includes a mounting frame 100, an air blowing assembly and a dust suction assembly. The mounting frame 100 is formed with a dust removal channel 110, which accommodates the pole ear of the pole piece 120 to pass through; the air blowing assembly is arranged on the mounting frame 100, and has an air outlet 130 connected to the dust removal channel 110, and the air outlet 130 blows air into the dust removal channel 110 to lift dust on the surface of the pole ear of the pole piece 120; the dust suction assembly is arranged on the mounting frame 100, and has a dust suction port 140 connected to the dust removal channel 110, and the dust suction port 140 is arranged in the air outlet direction of the air outlet 130 to extract the raised dust.

[0035] Therefore, an air outlet 130 and a dust suction port 140 are arranged on the dust removal channel 110, and the pole ear of the pole piece 120 enters the dust removal channel 110. The air outlet 130 can blow air to the pole ear to lift up the dust hidden in the folding of the pole ear. At the same time, the dust suction port 140 can extract the dust raised in the dust removal channel 110 by means of vacuum negative pressure, thereby solving the problem that the folding of the pole ear is difficult to remove. At the same time, the dust removal channel 110 is relatively small, and the dust removal channel 110 can limit the movement of the raised dust. The dust suction port 140 can quickly extract the dust, greatly reducing the flow of the raised dust out of the dust removal channel 110, and then fully removing the dust on the surface of the pole ear, improving the cleanliness of the pole ear surface, and improving the quality of the battery cell.

[0036] In some embodiments of the present invention, referring to Figure 2 and Figure 3 The dust removal channel 110 has a first side surface and a second side surface that are opposite to each other, and the air outlet 130 is located on the first side surface and / or the second side surface.

[0037] It can be understood that the pole piece 120 moves in one direction within the dust removal channel 110, and the air outlet 130 can be arranged on the side wall of the dust removal channel 110 in the path where the pole piece 120 moves. For example, when the pole piece 120 moves from top to bottom through the dust removal channel 110, the air outlet 130 is located on the first side and / or the second side, and the first side and the second side are the horizontally opposite sides of the dust removal channel 110, so that the air outlet 130 can remove dust from the pole ear from two directions.

[0038] In some embodiments of the present invention, the dust removal channel 110 has a third side surface, the third side surface is adjacent to the first side surface and the second side surface, and the dust suction port 140 is located on the third side surface.

[0039] It can be understood that the dust suction port 140 is adjacent to the air outlet 130 , and the dust raised by the air outlet 130 blowing toward the pole ear can be close to the dust suction port 140 , and the dust suction port 140 can quickly extract the raised dust, greatly reducing the dust flowing out of the dust removal channel 110 .

[0040] In some embodiments of the present invention, referring to Figure 3 The air outlet 130 is arranged in a strip shape along the extension direction of the dust removal channel 110. Such arrangement of the air outlet 130 can increase the air outlet volume of the air outlet 130 and increase the contact area between the airflow and the tab, which is beneficial to improving the dust removal efficiency and improving the cleanliness of the tab surface.

[0041] In some embodiments of the present invention, the blowing assembly has a nozzle head 150, which is provided with an air outlet 130, and the mounting frame 100 is provided with an adjusting member, which is used to adjust the orientation of the nozzle head 150 to change the jet direction of the air outlet 130 on the cross section of the dust removal channel 110.

[0042] It is understandable that by adjusting the position of the nozzle 150 using the adjustment member, the nozzle direction of the air outlet 130 can be changed to accurately face the tab portion where a lot of dust is hidden, so that the nozzle 150 can achieve maximum cleaning efficiency.

[0043] In some embodiments of the present invention, the adjusting member is a bolt 170, and the mounting frame 100 has a first mounting plate 160, which is connected to the nozzle head 150 via the bolt 170. It can be understood that the bolt 170 has a simple structure. By loosening the bolt 170, the angle of the nozzle head 150 can be adjusted, and the adjustment is simple.

[0044] In some embodiments of the present invention, the dust collection assembly has a dust collection tube 180 , the dust collection tube 180 is provided with a dust collection port 140 , and the mounting frame 100 has a second mounting plate 220 , which is connected to the dust collection tube 180 .

[0045] It should be noted that the dust suction pipe 180 is connected to a vacuum cleaner. Under the suction action of the vacuum cleaner, a local vacuum is formed in the dust removal channel 110 near the dust suction port 140, so that the dust suction port 140 can extract the dust in the dust removal channel 110 in a negative pressure manner.

[0046] In some embodiments of the present invention, referring to Figure 4 The dust suction pipe 180 has a collecting pipe section 190 , and the collecting pipe section 190 is expanded in the direction close to the dust suction port 140 , thereby increasing the volume of the collecting pipe section 190 and facilitating the dust suction pipe 180 to collect dust.

[0047] Throughout this specification, references to terms such as "one embodiment, some embodiments, exemplary embodiments, examples, specific examples, or some examples" indicate that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, illustrative uses of these terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
