[0056] Due to the matching arrangement of the first driving groove 14 and the first driving rod 20, and the first driving groove 14 including the first arc portion 17, the second arc portion 18 and the straight portion 19, when the step roller 8 rotates, when the first driving rod 20 is located in the first arc portion 17, the two sliding frames 13 are relatively stationary, and at this time, the second driving rod 23 is located in the third arc portion 21, and the rotating column 31 will not be subjected to rotational extrusion;

[0057] When the first driving rod 20 gradually moves from the straight portion 19 to the second arc portion 18, the two sliding frames 13 approach each other along the X-axis guide rail 11, and the two sliding frames 13 gradually clamp the protective skin 47 at the end of the wire harness.

[0065] Wire stripping operation

[0066] Wire stripping mechanism 2: The wire stripping process is achieved through the step roller 8 on the turntable 7 and its complex mechanical linkage. The motor 24 drives the step roller 8 to rotate, and the rotation stability is ensured by the meshing of the rack 25 and the gear 26. The first drive groove 14 and the second drive groove 15 control the sliding of the slide frame 13 along the X-axis guide rail 11 and the Y-axis guide rail 12 respectively.

[0067] A processing technology for a wire harness production device with a wiring terminal comprises the following steps:

[0068] S1: Wire harness introduction

[0069] The wire harness is grabbed and fixed by the finger cylinder of the XY-axis conveying mechanism, and then passes through the through hole between the two cutting knives in the wire stripping mechanism;

[0074] Clamping the protective skin 47: When the first driving rod 20 gradually moves from the straight portion 19 to the second arc portion 18, the two sliding frames 13 approach each other along the X-axis guide rail 11 and gradually clamp the protective skin 47 at the end of the wire harness.

[0075] Cutting the protective skin 47: When the first driving rod 20 moves to the front half of the second arc portion 18, the two cutting knives 16 completely cut the protective skin 47, and the sliding frame 13 completely clamps the protective skin 47 at the end of the wire harness.

[0076] Circular cutting: Then, the second driving rod 23 enters the front half of the adjusting part 22, so that the sliding frame 13 can move along the Y-axis guide rail 12, and the third driving rod 32 squeezes the rotating column 31, prompting the rotating column 31 to move into the fixed cylinder 30, and the rotating column 31, the sliding frame 13, the turntable 7, and the connecting plate 10 rotate together, and the cutting knife 16 performs a circular cut on the protective skin 47.

[0077] Separating the protective skin: The sliding frame 13 clamps the protective skin 47, and the cut protective skin 47 drives the plurality of copper wires 46 to rotate, so that the plurality of copper wires 46 are wound in a spiral shape, and the protective skin 47 is gradually separated from the copper wires.

[0078] Reset to prepare for the next cycle: When the first drive rod 20 moves to the second half of the second arc portion 18, the sliding frame 13 moves in the reverse direction, the rotating column 31 moves out of the fixed cylinder 30, and all components rotate in the reverse direction to prepare for the next cycle.

[0079] S4: Wire harness end processing

[0080] After the stripping is completed, the XY-axis conveying mechanism 4 moves the spiral-shaped copper wire 46 at the end of the wire harness to the crimping station of the terminal crimping machine 3;

[0081] S5: Crimp terminal

[0082] At the terminal crimping machine 3, the pre-prepared terminal and the end of the wire harness are crimped and connected together to complete the assembly of the wire harness and the terminal;

[0083] S6: Finished product output

[0084] After crimping is completed, the wire harness with the terminal block is moved out of the processing area by the XY-axis conveying mechanism 4 and is ready to enter the subsequent process;

[0085] S7: Reset and loop

[0086] Each mechanism is reset and ready to process the next wire harness.

11. A wire harness production device with a terminal block according to claim 2, characterized in that: The cutting blade (16) has a V-shaped blade edge, and the cutting blade (16) is detachably connected to the sliding frame (13).

12. A processing technology using a wire harness production device with a terminal block according to any one of claims 2 to 11, characterized in that: The steps include: S1: Wire harness introduction The wire harness is grasped and fixed by the finger cylinder (41) of the XY axis conveying mechanism (4), and then passes through the through hole between the two cutting knives (16) in the wire stripping mechanism (2); S2: Protective leather cutting The motor (24) is started, and through a series of mechanical transmissions, the cutting knife (16) performs a cutting action, first clamping the protective skin (47) at the end of the wire harness and cutting a slit; S3: Circular cutting and separation of the protective skin (47) The cutting knife (16) continues to move, cutting the protective skin (47) in a circular manner, while driving the copper wire to wind in a spiral shape, and the protective skin (47) is gradually separated from the copper wire; S4: Wire harness end processing After the wire stripping is completed, the XY-axis conveying mechanism (4) moves the spiral-shaped copper wire (46) at the end of the wire harness to the pressing station of the terminal crimping machine (3); S5: Crimp terminal At the terminal crimping machine (3), the pre-prepared terminal and the end of the wire harness are crimped and connected together to complete the assembly of the wire harness and the terminal; S6: Finished product output After crimping is completed, the wire harness with the terminal block is moved out of the processing area by the XY-axis conveying mechanism (4) and is ready to enter the subsequent process; S7: Reset and loop Each mechanism is reset and ready to process the next wire harness.
