Automatic wire threading method for wire cutting

The invention discloses an automatic wire threading method for linear cutting. The automatic wire threading method at least comprises the following steps that automatic wire threading is started; detecting whether a copper wire exists; the copper wire is straightened, if straightening fails, the result of automatic threading failure is output, and if straightening succeeds, the next step is executed; the copper wire is cut off, if cutting fails, the result of automatic threading failure is output, and if cutting succeeds, the next step is executed; judging whether the mechanism has wires or not; if no yarn exists, waste yarn is discharged, and if waste yarn discharging fails, the result of automatic yarn penetrating failure is output; if the silk exists, entering the next step; starting wire threading, and if wire threading fails, outputting a result of automatic wire threading failure; and if the threading is successful, outputting a result of automatic threading success. 本发明公开了一种线切割自动穿丝方法，至少包括如下流程：开始自动穿丝；检测
