Description

Technical Field

[0001] This invention relates to the field of wire processing technology, and in particular to a double-wire cutting processing device for shielded wire. Background Technology

[0002] The development of new energy vehicles is progressing rapidly, and the use of high-voltage wires in these vehicles is also expanding accordingly. To achieve a better human-machine interaction experience, the intelligent driving technology adopted by new energy vehicles requires better electromagnetic interference resistance for signal transmission, leading to the extensive use of shielded wires.

[0003] Automotive wiring harnesses typically consist of an outer insulation layer, a shielding layer, an inner insulation layer, and a core wire layer. Currently, wiring harness manufacturers often use a series of single-machine processing methods to strip the insulation of these types of wires, including equipment for stripping the outer insulation, manual processing of the shielding layer, equipment for cutting the shielding layer, and equipment for stripping the inner insulation layer. Some manufacturers also use equipment to strip the outer insulation, cut the shielding layer, and strip the inner insulation layer of a single wire.

[0004] However, automotive connectors typically have two circuits, meaning that two wires are required for the two holes of a connector. Furthermore, many connectors have a tail cap and waterproof plug as a single unit. Traditional wire processing requires two separate processes to thread the tail cap and waterproof plug, resulting in low efficiency. Summary of the Invention

[0035] The upper blade guard assembly 63 includes an upper forming blade 631, an upper spring seat 632, an upper blade guard 633, an upper cover plate 634, an upper zero-cutting blade 635, an anti-sticking blade cylinder 636, and a pressure tongue 637.

The lower guard blade 643 has limit protrusions on its upper and lower sides to slide up and down within the limit range of the lower cover plate 644. The lower spring seat 642 is mounted below the lower guard blade 643. A compression spring is provided between the lower spring seat 642 and the lower guard blade 643. Under the action of the compression spring, the lower guard blade 643 maintains an upward sliding force along the lower cover plate 644. The blade shapes of the upper forming blade 631 and the lower forming blade 641 are modeled after the diameter of the outer insulation layer and the diameter of the shielding layer of the wire. When the upper guard blade assembly 63 and the lower guard blade assembly... When 64 is closed, the upper forming blade 631 and the lower forming blade 641 cut precisely at the root of the outer insulation without damaging the shielding layer. When the upper guard blade 633 and the lower guard blade 643 encounter the outer insulation of the conductor, the compression spring compresses the upper guard blade 633 and the lower guard blade 643 to avoid the conductor along the outer diameter, thereby wrapping and supporting the root of the conductor for positioning. This plays a key role in the round cutting of the conductor's outer sheath. After the outer insulation is pulled off, the pressure tongue 637 extends along the inner side of the upper forming blade 631 under the action of the anti-sticking blade cylinder 636, preventing the pulled-off outer insulation from sticking to the upper forming blade 631 or the lower forming blade 641. This is to prevent poor wire stripping caused by waste material sticking to the blade when stripping a conductor.

A cutting punch 76 is connected to the punch seat 75. The cutting punch 76 is tubular and can penetrate the inner insulation layer of the wire. When the wire shielding mesh opening is opened in an "umbrella" shape by the upper shielding mesh knife group 68 and the lower shielding mesh knife group 69, the cutting punch 76 approaches the end of the wire under the drive of the XY moving module 2. The punching cylinder 71 drives the splined shaft 74 to drive the cutting punch 76 through the inner insulation layer of the wire, placing the wire shielding layer between the cutting punch 76 and the die 78.

The vacuum generator 96 draws away the shielding layer waste through the hose and collects it.

[0041] The implementation principle of the shielded wire double-wire cutting processing device in this application embodiment is as follows: When the equipment is in standby mode, the wire clamp module 81 is in the open state. The slide cylinder 823 drives the gripper cylinder 824 and the trigger rod 826 to move downwards. Two wires are manually inserted, and the ends of the wires contact the trigger rod 826, triggering the automatic operation of the equipment. The wire clamp module 81 clamps the wires, and the XY moving module 2 drives the cutting assembly 6 to move above the wires. The cutting assembly 6 peels off the outer insulation of the wires, and the waste suction module... 9. The waste material of the outer insulation is sucked away. The XY moving module 2 drives the upper shielding mesh knife group 68 and the lower shielding mesh knife group 69 to move above the conductor. The upper shielding mesh knife group 68 and the lower shielding mesh knife group 69 open and close repeatedly to open the shielding mesh opening in an "umbrella" shape. At the same time, the shielding mesh is cut and the waste suction module 9 sucks away the scattered shielding layer. The XY moving module 2 drives the punching assembly 7 to move to the front of the conductor. The XY moving module 2 and the punching electric cylinder 71 drive the cutting punch 76 to enter the shielding mesh opening and penetrate. The shielding mesh is inserted into the inner insulation layer and positioned between the cutting punch 76 and the die 78. Under the contact movement of the die 78 and the cutting punch 76, the shielding layer is punched and cut. During the punching process, the auxiliary clamping assembly 82 clamps the wire with a small clamping force. The clamping module 81 releases to promptly release the bending deformation of the wire caused by the punching, resulting in a smooth cut in the shielding mesh. The waste suction module 9 sucks away the scattered shielding layer. After the shielding layer is cut, the clamping module 81 clamps the wire, and the auxiliary clamping assembly 82 releases. Driven by the knife holder drive module 5, the upper shielding mesh knife and the lower shielding mesh knife group 69 open the shielding mesh opening again and cut the shielding mesh. The waste suction module 9 sucks away the scattered shielding layer. Driven by the XY movement module 2, the cutter assembly 6 moves to the front of the conductor. The upper guard knife group 63 and the lower guard knife group 64 strip or partially strip the inner insulation layer. Partial stripping means that the insulation is cut without being pulled off the conductor, which can protect the copper wires in the core layer from spreading and is beneficial to the flow of the wire harness during the production process.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
