The material collecting assembly 9 is used for collecting the cut material.
The strip is taken from an amorphous coil material and is conveyed forwards under the friction action of a strip conveying roller after being subjected to deviation correction by a strip deviation corrector 2; during cutting operation, the strip is adsorbed on a plane in a laser cutting area 6 through a vacuum adsorption assembly 5, so that displacement during cutting is prevented; the cut strip is sent to the material rack 9 through a second conveying roller to be stored.
Further, the first conveying assembly comprises a first strip conveying roller 3 and a second strip conveying roller 4, and the strip deviation corrector 2, the first strip conveying roller 3, the second strip conveying roller 4 and the vacuum adsorption assembly 5 are connected.
Further, the second conveying assembly comprises a third strip conveying roller 7 and a fourth strip conveying roller 8, and the laser cutting area 6, the third strip conveying roller 7, the fourth strip conveying roller 8 and the material collecting assembly 9 are connected in sequence.
Further, the vacuum adsorption component 5 comprises a plurality of air holes, and the air holes face to one side of the strip.
Further, the laser cutting assembly comprises a galvanometer assembly 12, and the galvanometer assembly 12 is connected with the laser generator 10.
Further, the strip deviation rectifying machine 2 comprises a laser assembly and a material roller which are connected with each other, and the material roller can be inclined.

Further, the laser power of the laser generator 10 is not lower than 75w, the diameter of the light spot is not more than 50um, and the scanning speed of the light spot is 500-2000 mm/s.
Further, the strip deviation rectifying machine 2 is connected with the amorphous strip coil stock 1. The relative position of the coil stock and the strip deviation rectifying machine 2 is not strictly required, and the strip can smoothly enter the strip deviation rectifying machine 2.
Further, the amorphous strip coil 1 is a single-layer amorphous strip coil or a multi-layer amorphous strip coil.
The amorphous strip coil stock 1 can be a single-layer coil stock or a multi-layer coil stock; the strip deviation corrector 2 is used for detecting the side edge position of the strip through laser and ensuring that the relative position of the amorphous strip coil 1 on the material roller is kept constant by adjusting the tiltable material roller on the strip deviation corrector; the first strip feed roller 3, the second strip feed roller 4, the third strip feed roller 7 and the fourth strip feed roller 8 are strip feed rollers serving to apply a suitable traction to the strip; the vacuum adsorption component 5 is provided with a plurality of air holes on one side facing the strip material, the vacuum adsorption component 5 is continuously vacuumized to play a role in adsorbing and fixing the strip material, and the strip material can be prevented from sliding due to the tension of the strip material at the moment when the strip material is to be cut off; a laser cutting area 6; in addition, the laser transverse shearing machine for blanking the amorphous strip needs to be provided with a corresponding laser cutting assembly.
