[0032] Please refer to Figures 8 to 11The clamp 8 comprises a base 81, a pair of arms 82, a pair of buffer rollers 83 and an elastic element 84. The base 81 has a side seat 81a, and a positioning groove 811 is formed on the upper side of the side seat 81a for inserting a battery cell. After the battery cell is inserted into the positioning groove 811, the widest plane (i.e. the surface or back surface) of the battery cell is perpendicular to the length direction of the air knife 5.

The two ends of the elastic element 84 are respectively connected to the two arms 82, so that the two arms 82 swing towards each other. The elastic element 84 is a tension spring. By connecting the two arms 82 through the elastic element 84, the two arms 82 can clamp the battery cell, and by arranging the buffer rollers 83 on the upper ends of the arms 82, the arms 82 can avoid the battery cell when the battery cell is inserted from top to bottom between the two arms 82, so as to facilitate the quick installation of the battery cell into the clamp 8, and the buffer rollers 83 can also buffer the battery cell to prevent the arms 82 from damaging the surface of the battery cell. Specifically, the arms 82 are respectively provided with an elastic adjusting mechanism 85 for adjusting the elastic force of the elastic element 84. The elastic adjusting mechanism 85 comprises an adjusting block 851 and an adjusting screw 852.

By adjusting the position of the adjusting block 851 relative to the arm 82 through the adjusting screw 852, the adjusting block 851 provides different pulling forces to the elastic element 84, so as to adjust the elastic force of the elastic element 84 to the arm 82, so that the clamp 8 can clamp battery cells with different thicknesses, and the applicability of the clamp 8 is improved.

[0033] Again, for example Figure 10 and Figure 11As shown, the clamp 8 further comprises a pull rod 86, which is T-shaped and has three ends, the base 81 is provided with a slot 812 on the surface, two opposite ends of the pull rod 86 are respectively pivoted with the two supporting arms 82, and the third end of the pull rod 86 is slidingly inserted into the slot 812. By matching the pull rod 86 and the slot 812, the pull rod 86 can ensure that the two supporting arms 82 can be kept symmetrical, so that the battery cell can be clamped in the central position by the two supporting arms 82 and kept stable, thereby improving the stability and reliability of the equipment operation. The clamp 8 comprises a detection element 87, which is located between the two supporting arms 82 and fixedly arranged on the base 81, so as to detect whether the battery cell is inserted in place.

[0034] In combination with the above and the accompanying drawings, the working principle of the battery cell surface dust removal device 100 of the utility model will be described in detail as follows:

[0035] Firstly, a plurality of battery cells are vertically inserted into the clamp 8 in sequence, so that the two supporting arms 82 on each clamp 8 clamp the battery cell together. At this time, the lifting driving mechanism 2 is started to drive the lifting platform 3 to move downward, and the lifting platform 3 drives the upper cover 4, the air knife 5 and the air knife lifting mechanism 6 to move downward. Finally, the upper cover 4 is covered with the lower cover 7. At this time, the air supply device supplies air to the air knife 5, and the air knife 5 blows high-speed airflow to the battery cell. At the same time, the air knife lifting mechanism 6 drives the lifting frame 64 to descend, and then drives the air knife 5 to slowly descend. The air knife 5 blows air to the battery cell from top to bottom. In this process, the high-speed airflow blows the dust away from the surface of the outside of the battery cell, and the dust floats in the inner cavity. At the same time, the air extraction device is started, and the air and dust in the inner cavity are discharged from the air extraction hole 71. When the dust removal is completed, the lifting driving mechanism 2 drives the lifting platform 3 to rise, and the upper cover 4 rises with the lifting platform 3 and leaves the lower cover 7. At this time, the battery cell can be taken out of the clamp 8.

[0036] Compared with the prior art, the utility model discloses a upper cover 4 and air knife lifting mechanism 6 are set up on the lifting platform 3, the lower cover 7 is set up below the upper cover 4, and the air knife 5 is set up in the upper cover 4, the clamp 8 is set up in the lower cover 7, the electric core is positioned by clamp 8 and is held, then the lifting driving mechanism 2 is utilized to drive the lifting platform 3 to move up and down, so that the upper cover 4 can be covered on the upper cover 4, and the working environment of the electric core is closed. Moreover, the air knife 5 is driven to move up and down in the inner cavity by utilizing the air knife lifting mechanism 6, and then the surface of the electric core can be blown from top to bottom, so that the dust on the surface of the electric core is blown away. In addition, the dust in the inner cavity is sucked away in time by utilizing the air suction device and the air suction device is communicated with the lower cover 7, so that the dust can be prevented from adhering to the surface of the electric core again and polluting the clamp 8 and other mechanisms, therefore, the utility model can effectively reduce the air and equipment pollution around, and greatly improve the quality of subsequent inkjet printing on the surface of the electric core.

[0037] The above disclosed is only the preferred embodiment of the utility model, of course can not with this to limit the utility model's right scope, therefore the equivalent change of the utility model application patent scope still belongs to the range that the utility model covers.
