The laser cutting device 100 is configured to control the positioning assembly 15 to emit the reference line 18 through the controller 48, and when the side of the positioning plate 14 is parallel to the reference line 18, the workpiece 16 to be cut is placed on the positioning plate 14, and the cutting head 10 performs cutting processing on the workpiece 16 to be cut.

[0039] In the above-mentioned laser cutting equipment 100, the positioning component 15 is controlled by the controller 48 to emit a reference line 18, and the positioning plate 14 is placed on the cutting platform 12. When the side of the positioning plate 14 is parallel to the reference line 18, the workpiece 16 to be cut is placed on the positioning plate 14, so that the workpiece 16 to be cut can be position-corrected by the positioning plate 14, and then the cutting head 10 performs cutting processing on the workpiece 16 to be cut, thereby reducing the cutting processing error of the workpiece 16 to be cut and improving the qualified rate of the product.

When the side of the positioning plate 14 is not parallel to the reference line 18, the controller 48 can control the alarm component of the laser cutting equipment 100 to send a warning signal. That is to say, the positioning assembly 15 is controlled by the controller 48 to emit the reference line 18, and the positioning plate 14 is placed on the cutting platform 12. When the side of the positioning plate 14 is parallel to the reference line 18, the workpiece 16 to be cut is placed on the positioning plate 14, so that the workpiece 16 to be cut can be position-corrected by the positioning plate 14, and then the cutting head 10 performs cutting processing on the workpiece 16 to be cut, thereby reducing the cutting processing error of the workpiece 16 to be cut and improving the qualified rate of the product.

[0041] The laser cutting device 100 focuses the laser emitted from the cutting head 10 into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach a melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting. The cutting head 10 includes a laser.

[0042] The cutting shape required for the workpiece 16 to be cut can be a drawing pre-selected by the user, and the workpiece 16 to be cut is cut by the laser cutting device 100 at a ratio of 1:1 to the drawing.

The guide member 82 has a guide groove 84 , and the end of the frame 62 is disposed in the guide groove 84 .

[0080] In this way, the movable room of the frame 62 can be limited by the guide groove 84 , so that the end of the frame 62 can move along the guide groove 84 .

[0081] Specifically, along the D direction, guide members 82 are provided on both sides of the cutting platform 12, and the guide members 82 may be provided with guide grooves 84, and both ends of the frame 62 may be arranged in the slide grooves 70. The second transmission member 80 is movably connected to the guide member 82, and a portion of the second transmission member 80 may be located in the guide grooves 84. The second driving member 78 may be fixedly connected to the guide member 82. The second driving member 78 may drive both ends of the frame 62 to move in the guide grooves 84 through the second transmission member 80, thereby driving the frame 62 to move along the L direction.
