[0041] The workpiece to be cleaned in the embodiments of the present application can be an electric core or a workpiece that needs to be cleaned.

[0042] The clamping assembly 1 may include a first driving member, a first clamping block, a second driving member, a second clamping block, and a mounting bracket. The first driving member and the second driving member are both mounted on the mounting bracket. The first driving member is drivingly connected to the first clamping block, and the second driving member is drivingly connected to the second clamping block. The first clamping block and the second clamping block are arranged opposite to each other. The first driving member and the second driving member respectively drive the first clamping block and the second clamping block to approach each other to clamp the workpiece to be cleaned, and the first driving member and the second driving member respectively drive the first clamping block and the second clamping block to move away from each other to release the workpiece to be cleaned. The first driving member and the second driving member can be cylinders, electric cylinders, or linear motors.

[0043] The rotating assembly 2 can be a rotary cylinder or a rotary motor. Taking the rotary motor as an example, the drive shaft of the rotary motor is drivingly connected to the clamping assembly 1.

[0045] The lifting assembly 3 can be a cylinder, an electric cylinder, or a hydraulic cylinder.

[0046] After the cleaning device clamps the electric core to be cleaned through the clamping assembly 1, the lifting assembly 3 lifts the rotating assembly 2 and the clamping assembly 1, so that the electric core to be cleaned is lifted to the cleaning working position. The cleaning assembly 4 cleans the electric core to be cleaned located at the cleaning working position. During the cleaning process, the rotating assembly 2 rotates the clamping assembly 1 to rotate the electric core to be cleaned, so that the side surface of the electric core to be cleaned is cleaned, preventing the unclean side surface of the electric core from affecting the effect of subsequent processes, improving the product yield, and improving the production efficiency.

[0047] Further, the lifting assembly 3 lifts the electric core to be cleaned to the cleaning working position, which can make the side surface of the electric core to be cleaned more comprehensively exposed in the cleaning area of the cleaning assembly 4, improving the cleaning effect on the side surface of the electric core.

[0053] Due to the cumulative error during the assembly of the clamping assembly 1, the side surface of the workpiece to be cleaned on the clamping assembly 1 cannot be well exposed in the cleaning area of the cleaning assembly 4, resulting in poor cleaning effect of the workpiece to be cleaned and affecting the effect of subsequent processes. The adjusting assembly 5 can adjust the position of the clamping assembly 1 to make the workpiece to be cleaned located in the cleaning area of the cleaning assembly 4 and improve the cleaning effect.

[0056] When adjusting the position of the clamping assembly 1, only need to loosen the first fixing threaded member 52 so that the head of the first fixing threaded member 52 does not abut against the edge of the first adjusting waist-shaped hole 511, then move the first adjusting member 51 along the length direction of the first adjusting waist-shaped hole 511 to make the workpiece to be cleaned of the clamping assembly 1 located in the cleaning area of the cleaning assembly 4, and then tighten the first fixing threaded member 52 so that the head of the first fixing threaded member 52 abuts against the edge of the first adjusting waist-shaped hole 511, thus the position of the clamping assembly 1 can be fixed.

[0057] The first adjusting member 51 can be an adjusting plate or an adjusting block, and the first fixing threaded member 52 can be a screw or a bolt.

[0058] The adjusting assembly 5 further includes a second adjusting member 53 and a second fixing threaded member 54. The second adjusting member 53 is connected to the rotating assembly 2.

[0060] The second adjusting member 53 can be an adjusting plate or an adjusting block, and the second fixing threaded member 54 can be a screw or a bolt.

[0061] The adjustment component 5 of the embodiment of the present application can adjust the position of the clamping component 1 according to the work requirements without using a braking device.
