When the clamping jaws 50 and the crimping jaws 51 rotate to the bottom of the terminal feeder 6, the terminals are loaded. Then when the clamping jaws 50 and the crimping jaws 51 rotate to align with the wires, the material moving mechanism inserts the wires into the terminals of the clamping jaws 50 and the crimping jaws 51 to complete the crimping.

[0038] The lifting plate 19 is driven to rise and fall by the first pneumatic cylinder 18, thereby driving the sleeve 11 to rise and fall along the polygonal shaft 9, adjusting the position of the straightening wheel 12, and aligning the wire troughs 13 of different inner diameters with the first wire tube 16 and the second wire tube 17. At this time, the wire passes through the first wire tube 16, the straightening wheel 12, and the second wire tube 17. The first motor 14 drives the active gear 15 to rotate, and the meshing transmission between the gears drives the transmission gear 10 to rotate, thereby realizing the rotation of the sleeve 11 and the straightening wheel 12, and correcting and conveying the wire passing through the straightening mechanism 3.

At this time, the pneumatic clamp 44 is moved to the stripped wire, and the wire is clamped by the pneumatic clamp 44.

When the clamping claw 50 and the crimping claw 51 rotate to the bottom of the terminal feeder 6, the terminal is loaded, and then the clamping claw 50 and the crimping claw 51 rotate to align with the wire. At this time, the material moving mechanism inserts the wire into the terminal of the clamping claw 50 and the crimping claw 51 to complete the crimping, and then the clamping claw 50 and the crimping claw 51 are relaxed, and the material moving mechanism moves the wire out of the frame 1, and subsequently the third motor 46 drives the rotating plate 43 and the pneumatic clamping claw 44 to rotate to the unloading position, and the pneumatic clamping claw 44 releases the crimped wire.

[0039] The first pneumatic cylinder 18 drives the lifting plate 19 to rise and fall, thereby driving the sleeve 11 to rise and fall along the polygonal shaft 9, adjusting the position of the straightening wheel 12, and aligning the wire troughs 13 of different inner diameters with the first wire tube 16 and the second wire tube 17. At this time, the wire passes through the first wire tube 16, the straightening wheel 12, and the second wire tube 17. The first motor 14 drives the active gear 15 to rotate, and the meshing transmission between the gears drives the transmission gear 10 to rotate, thereby realizing the rotation of the sleeve 11 and the straightening wheel 12. At this time, the straightening mechanism 3 completes the correction and transportation of wires of different diameters.

[0040] Depending on the wire diameter, the second motor 35 drives the threaded rod 36 to rotate, thereby driving the threaded U-shaped seat 24 to translate. At this time, through the cooperation of the polygonal slide column 39 and the guide plate 40, the two U-shaped seats 24 move synchronously along the guide rod 23, and the polygonal slide column 39 moves along the third guide rail of the guide frame 37 through the slider 38.
