Acquiring the transportation speed of the strip-shaped battery pole piece, wherein the transportation speed of the strip-shaped battery pole piece can be acquired through an encoder; or the transportation speed of the strip-shaped battery pole piece can be acquired through a photoelectric sensor; other ways of acquiring the speed are also possible.
S20, controlling the laser 10 to emit laser to hit the surface of the strip-shaped battery pole piece to form a light spot, and enabling the light spot to have a transverse speed along a first direction, wherein the transverse speed is equal to the conveying speed of the strip-shaped battery pole piece;
the laser 10 is controlled to emit laser to form a light spot on the surface of the strip-shaped battery pole piece, and the light spot has a transverse speed along the first direction. The implementation mode is as follows: with the vibrating mirror of the laser 10, the laser is reflected by the vibrating mirror and impinges on the strip-shaped battery pole piece to form a light spot, wherein the vibrating mirror swings to swing the emitted laser toward the first direction, so that the light spot has a lateral velocity in the first direction, which is equal to the transport velocity of the strip-shaped battery pole piece, and specifically, the angular velocity of the swinging of the vibrating mirror can be calculated according to the transport velocity of the strip-shaped battery pole piece, the distance between the vibrating mirror and the strip-shaped battery pole piece, and the like. The implementation mode is two: the motor drives the laser 10 to swing towards the first direction, so that laser emitted by the laser 10 swings towards the first direction, the light spot has a transverse speed along the first direction, the transverse speed is equal to the transportation speed of the strip-shaped battery pole piece, and the angular speed of the oscillating mirror can be calculated according to the transportation speed of the strip-shaped battery pole piece, the distance between the laser 10 and the strip-shaped battery pole piece and the like. Of course, other implementations are possible.
And S30, controlling the laser 10 to move along a second direction intersecting with the first direction, so that the light spot has a longitudinal speed along the second direction, and cutting and separating the sheet-shaped battery pole piece.

The laser 10 can be driven to move along the second direction by a linear motor; the laser 10 can also be driven to move along the second direction by a screw rod-motor; other ways of driving the laser 10 in the second direction are also possible.
In this embodiment, the transportation speed of the strip-shaped battery pole piece can be obtained by keeping the strip-shaped battery pole piece transported in the first direction and then obtaining the transportation speed of the strip-shaped battery pole piece. Then, the laser 10 is controlled to emit laser to strike on the surface of the strip-shaped battery pole piece to form a light spot, and the light spot has a transverse speed along the first direction, wherein the transverse speed is equal to the transportation speed of the strip-shaped battery pole piece, so that the light spot moves along with the strip-shaped battery pole piece. Then, the laser 10 is controlled to move along a second direction intersecting with the first direction, so that the light spot has a longitudinal speed along the second direction, and the sheet-shaped battery pole piece is cut and separated, so that the high-energy light spot cuts the belt-shaped battery pole piece.

the laser 10 is mounted on the moving part of the linear motor 30, and the linear motor 30 drives the laser 10 to move in the opposite direction of the second direction, so that the light spot cuts and separates the next sheet-shaped battery pole piece.
Step S70: controlling the laser 10 to stop emitting laser light;
the software of the computer controls the laser 10 to stop emitting laser and controls the galvanometer of the laser 10 to reset so as to carry out the next cutting.
And S80, repeating the process steps from S20 to S70.
By repeating the process steps from S20 to S70, the sheet-shaped battery pole pieces can be continuously cut on the strip-shaped battery pole pieces so as to cut a plurality of sheet-shaped battery pole pieces, so that the cutting can be continuously and repeatedly carried out, and the cutting efficiency of the battery pole pieces is improved.
By adopting the design, the transportation speed of the strip-shaped battery pole piece can be obtained by keeping the strip-shaped battery pole piece transported in the first direction and then acquiring the transportation speed of the strip-shaped battery pole piece. And then, controlling the laser emitted by the laser to hit the surface of the strip-shaped battery pole piece to form a light spot, and enabling the light spot to have a transverse speed along the first direction, wherein the transverse speed is equal to the transportation speed of the strip-shaped battery pole piece, so that the light spot moves along with the strip-shaped battery pole piece. Then, the laser is controlled to move along a second direction intersecting with the first direction, so that the light spot has a longitudinal speed along the second direction, and the sheet-shaped battery pole piece is cut and separated, so that the high-energy light spot is used for cutting the belt-shaped battery pole piece. Then, the laser 10 is controlled to stop emitting laser light, and the galvanometer of the laser 10 is controlled to be reset. And then, controlling the laser 10 to move along the direction opposite to the second direction so that the light spot cuts and separates the next sheet-shaped battery pole piece. And then controls the laser 10 to stop emitting laser light. Thus, the next sheet-shaped battery pole piece can be cut. And repeating the process steps from S20 to S70, and continuously cutting the strip-shaped battery pole piece to obtain a plurality of sheet-shaped battery pole pieces, so that the cutting can be continuously and repeatedly carried out, and the cutting efficiency of the battery pole pieces is improved. In addition, in the whole cutting process, the strip-shaped battery pole piece is kept in a transportation state, and the laser can cut without waiting for the deceleration and complete rest of the strip-shaped battery pole piece, so that the cutting efficiency can be improved.
