The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

The utility model provides a pole piece cleaning device which is suitable for an application scene of cleaning charged foreign matters and magnetic foreign matters adhered to the surface of a pole piece, does not need to scrape the pole piece, and can complete cleaning work under the condition of not damaging the pole piece.

In this embodiment, the pole piece cleaning apparatus described with reference to fig. 1 and 2 includes a housing 1, a voltage controller, a first metal plate 2, a second metal plate 3, a first magnetic plate 4, and a second magnetic plate 5.

The housing 1 is provided with a rectangular accommodating cavity 101 inside, the front wall of the accommodating cavity 101 is provided with a workpiece inlet 102 for the pole piece 7 to enter, and the rear wall of the housing 1 is provided with a workpiece outlet 103 for the pole piece 7 to leave.

The first metal plate 2 is located on the left wall surface of the accommodating cavity 101, and the second metal plate 3 is located on the right wall surface of the accommodating cavity 101, that is, the first metal plate 2, the pole piece 7 and the second metal plate 3 are sequentially arranged in the width direction of the pole piece 7. The first metal plate 2 and the second metal plate 3 are electrically connected to a voltage controller, and the voltage controller can output voltage, so that an electric field for adsorbing charged foreign matters on the pole piece 7 is formed between the first metal plate 2 and the second metal plate 3.

Optionally, the first metal plate 2 and the second metal plate 3 are arranged in parallel to improve the uniformity of the electric field.

It can be understood that the voltage controller adjusts the output voltage, i.e. the direction and intensity of the electric field between the first metal plate 2 and the second metal plate 3, and thus the adsorption intensity and speed of the charged impurities.

In this embodiment, the first metal plate 2 is located on the upper wall surface of the accommodating chamber 101, and the second magnetic plate 5 is located on the lower wall surface of the accommodating chamber 101, that is, the first magnetic plate 4, the pole piece 7, and the second magnetic plate 5 are sequentially arranged along the thickness direction of the pole piece 7, so that the first magnetic plate 4 can smoothly adsorb the magnetic foreign matter on the upper surface of the pole piece 7, and the second magnetic plate 5 can smoothly adsorb the magnetic foreign matter on the lower surface of the pole piece 7.

For example, the material detection device 6 is a photoelectric sensor, a camera, a weighing device, or the like.

Specifically, the working process of the pole piece cleaning device provided by the embodiment is as follows:

firstly, when the material detection device 6 does not detect the pole piece 7, the voltage controller is in standby, and no electric field exists between the first metal plate 2 and the second metal plate 3, so that energy consumption is saved;

when the material detection device 6 detects that the pole piece 7 exists at the workpiece inlet 102, the voltage controller works, and an electric field from left to right or from right to left is formed between the first metal plate 2 and the second metal plate 3;

after the pole piece 7 enters the accommodating cavity 101, when the pole piece is located in a piece feeding space between the first metal plate 2 and the second metal plate 3, the charged foreign matters on the pole piece 7 can move left or right under the action of an electric field to be separated from the pole piece 7, the magnetic foreign matters on the upper surface of the pole piece 7 can move upwards under the action of the magnetic force of the first magnetic plate 4 to be separated from the pole piece 7, and the magnetic foreign matters on the lower surface of the pole piece 7 can move downwards under the action of the magnetic force of the second magnetic plate 5 to be separated from the pole piece 7, so that the cleaning work of the pole piece 7 is completed;

fourthly, after the cleaning is finished, the pole piece 7 leaves the accommodating cavity 101 from the piece outlet 103.

The pole piece cleaning equipment that this embodiment provided has following advantage:

firstly, the pole piece 7 does not need to be scraped, the surface of the pole piece 7 is protected from being damaged, the working efficiency is high, and the production cost is favorably reduced;

magnetic plates with magnetism are used for adsorbing magnetic foreign matters on the upper surface and the lower surface of the pole piece 7, and extra energy consumption is not needed;

and thirdly, when the cleaning work is not carried out, the voltage controller is in a standby state, so that the electric energy is saved.
