[0046] As Figures 1 to 7 shown, a wire harness terminal riveting device 100 of the present utility model is used for installing a terminal 300 at the end of a wire harness 200, and specifically includes a peeling process and a terminal 300 riveting process. The wire harness terminal riveting device 100 includes a terminal feeding mechanism 110, a terminal crimping mechanism 120, a peeling mechanism 130, and a wire harness feeding mechanism 1322 first pushing cylinder; 140.

[0047] Please refer to Figures 1 - 4 shown, the terminal feeding mechanism 110 includes a feeding track 111, a back plate 112 provided at the rear side of the feeding track 111, a pushing block 113 movably connected above the feeding track 111, and a swing arm 114 connected to the pushing block 113; the swing arm 114 has a rotating end 1141 and a connecting end 1142, the rotating end 1141 is rotatably connected to the back plate 112, and the connecting end 1142 is fixedly connected to the pushing block 113. Wherein the feeding track 111 has a feeding end 1111 and a discharging end 1112, and a pushing surface 1131 is provided on one side of the pushing block 113 facing the discharging end 1112; an avoiding inclined surface 1132 is provided on one side of the pushing block 113 facing the feeding end 1111. A connecting notch 1143 is formed on the swing arm 114.

[0048] As Figure 4 shown, during actual processing, the terminals 300 are arranged in the feeding track 111 waiting for feeding. When feeding, the swing arm 114 will swing around the rotating end 1141. During the movement of the swing arm 114, the pushing surface 1131 of the pushing block 113 will abut against the inner wall of the terminal 300, and at this time, the terminal 300 will move forward along the feeding track 111 with the swing of the pushing block 113 for feeding. After the feeding is completed, due to the avoiding inclined surface 1132 provided on the pushing block 113, there is no interference between the pushing block 113 and the terminal 300 when the pushing block 113 retracts.

[0049] Specifically, a connecting member 115 is provided on the front end surface of the back plate 112, an activity slot 1151 is formed on the connecting member 115, and the rotating end 1141 of the swing arm 114 is connected in the activity slot 1151; the activity slot 1151 is strip-shaped, and the position of the swing arm 114 is adjusted by adjusting the position of the rotating end 1141 in the activity slot 1151.

[0050] Please refer to Figure 5 As shown, the terminal crimping mechanism 120 includes an upper die 121 and a lower die 122 which are arranged vertically aligned; a lifting block 123 is fixedly provided at the upper end of the upper die 121, and a lifting cylinder 124 is provided at the upper end of the lifting block 123. The lifting cylinder 124 drives the lifting block 123 to lift and lower, so as to make the upper die 121 and the lower die 122 approach each other, and crimp the terminal 300 to the end of the wire harness 200.

[0051] In addition, a connecting rod 125 is provided between the swing arm 114 and the lifting block 123; in this embodiment, the connecting rod 125 includes a first movable rod and a second movable rod which are rotatably connected, increasing the freedom of movement; under the action of the connecting rod 125, when the lifting block 123 lifts and lowers, the pusher block 113 will swing accordingly. Therefore, the terminal feeding mechanism 110 and the terminal crimping mechanism 120 only need to be synchronously driven by one lifting cylinder 124, reducing the overall structural volume and making the structure more compact. Specifically, a connecting member 126 is provided on the side of the lifting block 123, one end of the connecting rod 125 is connected to the connecting slot 1143, and the other end of the connecting rod 125 is rotatably connected to the connecting member 126.

[0053] Please refer to Figure 6 As shown, the wire stripping mechanism 130 includes a skin cutting module 131 and a first sliding module 132 connected to the skin cutting module 131; the first sliding module 132 drives the skin cutting module 131 to move towards the wire harness, and the skin cutting module 131 moves to the end of the wire harness 200 to cut the outer skin. After the skin cutting is completed, the first sliding module 132 drives the skin cutting module 131 to move away from the wire harness, and takes out the cut outer skin during the movement.

[0054] Specifically, the skin cutting module 131 includes a first clamping cylinder 1311 and two cutting knives 1312. The cutting knives 1312 are drivingly connected to the first clamping cylinder 1311 and symmetrically distributed at the driving end of the first clamping cylinder 1311. The first clamping cylinder 1311 drives the two cutting knives 1312 to approach each other to cut the outer skin of the wire harness 200. Further, cutting grooves are provided on the opposite surfaces of the two cutting knives 1312. When the two cutting knives 1312 are joined together, there is a gap in the middle to prevent the wire harness 200 from being cut off. The first sliding module 132 includes a sliding block 1321 fixed to the lower end of the skin cutting module 131 and a first pushing cylinder drivingly connected to the sliding block 1321. The transmission shaft of the first pushing cylinder expands and contracts to drive the sliding block 1321 to move.

The second sliding module 142 includes a sliding seat 1421 fixed to the lower end of the clamping module 141 and a second pushing cylinder 1422 drivingly connected to the sliding seat 1421.

[0056] In addition, the wire harness terminal riveting device 100 of the present utility model further includes an induction mechanism 150. The induction mechanism 150 includes a connecting frame 151 provided on one side of the lower die 122 and a vision sensor 152 assembled on the connecting frame 151. The detection end of the vision sensor 152 faces the lower die 122, and the vision sensor 152 is used to detect whether the wire harness 200 enters the processing station.

[0057] The working steps of the wire harness terminal riveting device 100 involved in the present utility model are as follows: Place the terminal 300 to be processed on the feeding track 111, manually place the wire harness 200 to be processed on the clamping module 141, the clamping module 141 clamps the wire harness 200, and the second sliding module 142 drives the end of the wire harness 200 to move above the lower die 122. The first sliding module 132 drives the skin cutting module 131 to approach the wire harness 200 and cut the outer skin of the end of the wire harness 200. After completion, the first sliding module 132 retracts to make the outer skin fall off, completing the skin peeling. The lifting cylinder 124 drives the upper die 121 to move downward. During the downward movement of the upper die 121, the pushing block 113 pushes the terminal 300 to move towards the lower die 122. Finally, the terminal 300 moves directly above the wire harness 200, and the upper die 121 and the lower die 122 close to complete the riveting of the terminal 300.
