[0034] The following is combined with Figure 1 - Attachment Figure 6 The present invention is described in further detail.

[0035] Example 1: Reference Figure 1 - Figure 6 An electronic wiring harness terminal crimping device includes a conveying structure for clamping and conveying cables. The conveying structure includes a platform 1, on which a conveyor belt 2 is arranged, and above the conveyor belt 2 is a conveyor belt 3 that cooperates with the conveyor belt 2. The conveyor belts 1 and 23 clamp and convey the cables.

[0036] A wire stripping mechanism 4 and a clamping mechanism 5 are sequentially arranged along the conveying direction on one side of the conveying structure. The wire stripping mechanism 4 includes two coaxial elastically connected wire stripping rods 41 and a shearing end 411 located at the front end of the two wire stripping rods 41. An operating structure is arranged below the wire stripping rods 41. The operating structure includes a horizontally displaced transmission part, which is fixed by two steel wires 44 and the wire stripping rods 41. An empty groove 413 is provided at the midline position of the wire stripping rod 41. One end of the steel wire 44 is fixed on the inner wall of the wire stripping rod 41, and then bypasses the reversing column, passes through the empty groove 413 and is fixedly connected with the connecting plate 45. The transmission part includes two sections of movement trends. The first section causes the two wire stripping rods 41 to move relative to each other to shear the cable. The second section drives the wire stripping rod 41 to move as a whole away from the conveying structure to pull off the sheared insulation.

[0037] The two stripping rods 41 are welded with a resistance block 412 on the opposite sides. When the transmission part moves in the first section, the two resistance blocks 412 separate from each other. When the transmission part moves in the second section, the two resistance blocks 412 abut against each other. The function of the resistance block 412 is to limit the relative movement position of the two stripping rods 41 to avoid excessive movement. When the two resistance blocks 412 abut against each other, the cutting of the insulation is just completed without causing adverse effects on the wire core. When the two resistance blocks 412 abut against each other, the relative movement of the stripping rods 41 is limited, and the continued movement of the transmission part causes the stripping rods 41 to move as a whole. Since the cable is clamped by the conveying structure, the insulation can be removed from the wire core by the stripping rods 41.

[0038] The operating structure includes a fixed bracket 46, and the transmission part is installed on the bracket 46. The transmission part includes a horizontally arranged telescopic rod 47. The output end of the telescopic rod 47 is fixed to the connecting plate 45, and the steel wire 44 is fixed to the connecting plate 45. The telescopic rod 47 can adopt an electric, hydraulic or pneumatic structure. During operation, from 0 to stroke 1, the two steel wires 44 move to one side. At this time, the tension of the steel wire 44 overcomes the elastic force between the axes of the two stripping rods 41, so that the two shearing ends 411 are close to each other, and the openings of the two shearing ends 411 complete the cutting of the insulation skin; from stroke 2 to the end point, the steel wire 44 will move along the horizontal direction with the stripping rod 41 as a whole to complete the stripping of the insulation skin.

[0039] The wire stripping mechanism 4 also includes a reset structure, which includes a guide rail 461 welded on the bracket 46, a slide bar 42 is slidably embedded inside the guide rail 461, the slide bar 42 and the rotating shaft of the wire stripping rod 41 are fixed, the slide bar 42 and the guide rail 461 are elastically connected by a spring 48, and the two wire stripping rods 41 in the wire stripping mechanism 4 are provided with a torsion spring 48 to achieve the reset of the opening angle. The function of the reset structure is to reset the horizontal position of the wire stripping rod 41 when the telescopic rod 47 is reset, so as to ensure the stability of the position of the wire stripping rod 41 for cutting the cable next time. A reversing rod 43 is welded at the front end of the slide bar 42, and the reversing rod 43 turns the steel wire 44.

[0040] The clamping mechanism 5 includes a plurality of clamping blocks 56 that move synchronously centrifugally or centrifugally, and the clamping blocks 56 squeeze and fix the terminals. The clamping mechanism 5 also includes an arc-shaped horizontal receiving groove 51, and the receiving groove 51 is connected to a feeding groove 52 for loading materials above, and a cylinder 53 arranged parallel to the feeding groove 52 is installed below the feeding groove 52, and the end of the cylinder 53 is connected to a push rod 54, and the push rod 54 is slidably embedded in the receiving groove 51 and arranged coaxially with the receiving groove 51. The cylinder 53 reciprocates, and when it contracts, it will drive the push rod 54 to enter the bottom of the feeding groove 52, push the terminal inside the feeding groove 52 forward, and the terminal slides on the cable, and the subsequent terminal of the feeding groove 52 will be extended by the cylinder 53. After the push rod 54 is withdrawn, the position on the receiving groove 51 is supplemented to prepare for the follow-up.

[0041] A fixed disk 55 is arranged on the outside of the clamping block 56, and a connecting rod 561 is welded on the back of the clamping block 56. The connecting rod 561 penetrates the fixed disk 55 and extends to the outside of its back. A turntable 57 is coaxially arranged on the back of the fixed disk 55. A plurality of arc-shaped movable grooves 571 are provided on the turntable 57. The arc-shaped movable grooves 571 cooperate with the connecting rod 561, and the transmission clamping block 56 moves synchronously centrifugally or centripetally. A motor 58 is arranged on the outside of the fixed disk 55. The motor 58 utilizes gears and the toothed ring on the outside of the turntable 57 to mesh with each other to realize the transmission of the turntable 57. The arc-shaped movable grooves 571 are radially structured from the inside to the outside. When the outer side of the arc-shaped movable grooves 571 contacts the clamping block 56, the clamping block 56 is located in the standby position of the fixed disk 55. When the inner side of the arc-shaped movable grooves 571 contacts the clamping block 56, the clamping block 56 is in a clamping state, completing the clamping of the terminal and fixing it to the wire core.
