[0099] The working principle of this utility model:

[0100] The unwinding mechanism automatically unwinds the wound tape and passes through the correction roller 31. The correction sensor 34 detects whether the tape deviates from the position. If it is detected that the tape deviates from the set position, the unwinding moving mechanism and the unwinding mechanism are coordinated to correct the unwinding tape in real time, that is, the moving end of the unwinding linear reciprocating moving structure 61 drives the unwinding seat 62, the unwinding driving member 63 and the unwinding roller 64 to adjust the position. The tape passes through the tape splicing platform 91 for manual tape splicing. The tension detection component 2 is a tension sensing roller, which is used to detect the real-time tension of the tape. The tension sensing roller close to the unwinding mechanism transmits data to the unwinding mechanism and the unwinding control structure 65 to adjust the unwinding tension. The unwinding control structure 65 includes a magnetic powder clutch for controlling the tension of the tape, which can increase or decrease the tension of the tape through the magnetic powder clutch. The tape enters the correction execution structure, and the correction execution structure corrects the tape in real time according to the position of the tape sensed by the second correction detection structure B2. After being corrected before cutting, the material strip is conveyed to the laser cutting area 11, and the laser 48 performs ear forming processing on one side of the material strip. The material strip enters the traction roller 74, which is used to provide power to the material strip and convey the material strip forward. The material strip enters the dust removal roller 51 of the cleaning component 5, and the wind knife structure 53 above the dust removal roller 51 cleans the molten beads and dust on the front and back sides of the material strip. The wind knife structure 53 can be driven by the moving end of the wind knife moving structure 52 and move along the length direction of the dust removal roller 51. The material strip enters the tension sensing roller of the tension detection component 2, and the tension sensing roller detects the real-time tension of the material strip and transmits it to the traction and winding component 7. The traction and winding component 7 controls the winding tension in real time through the winding control structure 73 (the magnetic powder clutch is selected in this embodiment to increase or decrease the tension of the material strip) to ensure that the material strip is wound with constant tension. After that, it passes through one side of the magnetic plate 55. In this embodiment, two magnetic plates 55 are provided, one on the left and one on the right. The two magnetic plates 55 clean the iron filings on the front and back sides of the material strip. While the winding drive 71 drives the winding roller 72 to automatically rewind, the smoothing roller 83 of the smoothing assembly 8 smoothes the pole ears on the material strip. The function of the belt pressing assembly 10 is to press the material strip when replacing the reel on the winding roller 72. Fig. 9 In the figure, the dotted line part is the material strip.
