[0006] This wire harness stripping device is designed to adapt to multi-variety, small-batch production modes, enabling semi-automatic wire harness stripping. Specifically, the clamping unit and stripping unit have channels for the wire harness to pass through. The operator passes the wire harness through the channels, touches the trigger unit, and triggers a start signal. The control system then controls the clamping unit to clamp and fix the wire harness. Simultaneously, a second drive unit drives two sets of stripping blades to move closer together, causing the first and second blades of the two sets of stripping blades to cut into the wire harness insulation from both sides. The design controls the stroke of the drive blades to avoid damaging the core wires. Then, the first drive unit drives the stripping unit to move along a first direction, and under the pulling action of the blades, the insulation is peeled off. Afterwards, the device resets, the stripping blades and clamping unit release the wire harness, and the operator removes the wire harness, completing the operation. This design replaces manual stripping with blades, improving stripping efficiency and ensuring stripping quality. To accommodate wires of different thicknesses, the first blade of the stripping blade can be freely adjusted up and down along a third direction to change the blade spacing between the first and second blades, making it compatible with various wires without the need for disassembling and replacing the stripping blades, making it more convenient and faster.

[0007] Furthermore, the stripping tool also includes a tool holder connected to the output end of the second drive member. The tool holder is provided with a sliding guide rail. The first blade includes a cutting edge, a connecting part and a sliding part located on both sides of the cutting edge, and the sliding part is slidably connected to the sliding guide rail.

[0008] The tool holder has a recessed tool groove, the second blade is fixed at the bottom of the tool groove, the first blade is positioned above the second blade, and the first blade can slide in the tool groove in a third direction through the cooperation of the sliding part and the sliding guide rail.

[0009] Furthermore, a first transmission rod is rotatably provided on the tool holder, and a first through hole is provided on the connecting part, wherein the first transmission rod is threadedly connected to the first through hole.

The output end of the second driving element is connected with the stripping cutter slidingly arranged on the sliding table, and then the two groups of stripping cutters are driven to approach each other.

[0013] Further, the sliding table is provided with a rubber leakage hole between the two stripping cutters.

[0014] In order to avoid that the stripped rubber gathers on the sliding table and the base, affecting the stable operation of the equipment, the rubber leakage hole is arranged on the sliding table, and the rubber leakage hole is also arranged at the corresponding position of the base. A collecting container can be arranged below the base, and the stripped rubber directly falls into the collecting container through the rubber leakage hole.

[0015] Further, the touch opening unit comprises a mounting seat arranged on the sliding table and a touch switch slidingly arranged on the mounting seat.

[0016] Different types of wire harnesses may have different lengths of stripped rubber. In order to improve the compatibility of the equipment, the touch switch can be designed in a position-adjustable form. By changing the position of the touch switch, the length of the stripped rubber is changed, that is, the length of the stripped rubber is adjusted.

[0017] Further, the mounting seat comprises a hollow sliding groove and a second transmission rod rotatably arranged, the touch switch is provided with a sliding block embedded in the sliding groove, the sliding block is provided with a second through hole, and the second transmission rod passes through the second through hole and is threadedly connected with the second through hole.

[0018] The position adjustment of the touch switch is realized in a threaded transmission mode. The second transmission rod can be a screw rod, the second through hole is a threaded hole matched with the screw rod, and the end of the second transmission rod can be provided with a handle.

[0023] Further, the second clamping block comprises a clamping block seat connected with the output end of the third driving member, and a clamping head elastically connected with the clamping block seat.

[0024] In order to avoid indentation of the wiring harness caused by rigid clamping force during clamping, and to be compatible with wiring harnesses of different thicknesses, the second clamping block is a spring clamping block, i.e., the second clamping block is composed of a clamping block seat and a clamping head, and the two are elastically connected through a plurality of springs. During the process that the third driving member drives the second clamping block to contact and press the wiring harness, after the pressing head contacts the wiring harness, the springs play a role of transition and buffering, and the rigid pressing force is converted into a gradually changing pressing force, thereby avoiding indentation of the wiring harness.
