6. The automatic motor wiring harness terminal crimping machine according to claim 5, characterized in that: The fixed end of the second retractor (135) is fixedly connected to the main shaft (130), and the movable end of the second retractor (135) is connected to the slide seat (310).

7. The automatic motor wiring harness terminal crimping machine according to claim 2, characterized in that: The feeding slide (530) is fixedly connected to the support frame (100), and the lower end of the feeding slide (530) is butt-jointed with a limit baffle (531), and the limit baffle (531) is annularly wrapped around the outer surface of the cylinder (550).

8. The automatic motor wiring harness terminal crimping machine according to claim 3, characterized in that: The rotary driver (510) comprises a reduction motor (511), a driving wheel (513) and a driven wheel (515); the driving shaft of the reduction motor (511) is coaxially fixedly connected to the driving wheel (513); the driving wheel (513) is meshed with the driven wheel (515); and the driven wheel (515) is coaxially fixedly connected to the cylinder (550).

9. The automatic motor wiring harness terminal crimping machine according to claim 8, characterized in that: There are four terminal placement grooves (551), and the four terminal placement grooves (551) are evenly spaced and distributed in a ring. Each terminal placement groove 551 cooperates with the main shaft 130 and the limit baffle 531 to form a first work area (5511), a second work area (5512), a third work area (5513) and a fourth work area (5514).

10. A crimping method of an automated motor harness terminal crimping machine, comprising an automated motor harness terminal crimping machine according to any one of claims 1 to 9, characterized in that: The following steps are also included: S1. Place the terminal to be crimped on the feeding slideway (530), slide the terminal along the slideway into the first work area (5511), and drive the cylinder 550 to rotate by the rotary driver 510, so that the terminal in the first work area (5511) passes through the second work area (5512), the third work area (5513) and the fourth work area (5514) in sequence; S2, placing the wire harness to be crimped in the wire harness groove (311), so that the end of the wire harness is exposed to the length that needs to be cut, clamping the clamping cover (330) on the upper end of the wire harness groove (311) to achieve the clamping and fixing of the wire harness, and at the same time driving the first blade (710) installed at the end to cut the foreskin of the end of the wire harness. Under the downward pressure of the first blade (710), the upper surface of the wire harness is cut by the first blade (710), and the lower surface of the wire harness is cut by the second blade (730); S3, when the pressing cover (330) flips over the surface of the harness slot (311), the installed micro switch is triggered, so that the micro switch controls the reciprocating structure (750) to drive the second blade (730) to slide, and the reciprocating structure (750) pushes the second blade (730) to slide a distance away from the first blade (710) and then reset; S4, after the reciprocating structure (750) drives the second blade (730), the second retractor (135) drives the slide seat (310) to slide, and simultaneously drives the cut wire harness to slide toward the terminal side, so that the end of the cut wire harness is plugged into the terminal of the fourth workstation area (5514); S5. Control the first retractor (910) to drive the pressing head (930) to move downward, and perform a crimping operation on the terminals in the fourth workstation area (5514).
