Description

Technical Field

[0001] This utility model relates to the field of wire harness processing, specifically a coaxial cable shearing shielding mesh device. Background Technology

[0002] The rise of industries such as new energy, energy storage, data communication, and medical has increased the demand for wire harnesses, leading to more stringent quality requirements. This presents significant challenges to the wire harness manufacturing industry in terms of processing efficiency and cost control.

[0003] Current technologies for processing shielded wires include laser cutting, coaxial rotary cutting, extrusion cutting, and manual trimming. Laser cutting requires adjusting the focus, has difficulty controlling power, is slow, produces smoke, and can burn or damage the core wire insulation, leading to inconsistent product quality. Coaxial rotary cutting involves a blade directly cutting the shielding mesh through mechanical rotation. Because the shielding mesh wires are thin and tightly wound, close to the core wire insulation (which is not perfectly round and has dimensional tolerances), the cutting depth must be controlled to avoid damaging the insulation, making 100% removal impossible. Extrusion cutting uses two metal tubes to cut the mesh. This requires strict control over the tube material and fit, resulting in a short lifespan. Each wire specification requires a corresponding set of tubes, leading to a large number of tube specifications and frequent switching. Manual trimming of the shielding mesh ensures quality but results in low output and increased labor costs. Utility Model Content

[0042] In another embodiment of this application, a first parallel gripper cylinder 31 is fixed on the base plate 1 on the side of the conduit 28 away from the motherboard 2. A gripper 30 is fixed at the output end of the first parallel gripper cylinder 31. The gripper 30 is used to clamp the cable.

[0043] Work process:

[0044] The core wire is manually inserted into the conduit 28, with the shielding mesh outside the conduit 28. The first rotary motor 24 is started, causing the cutting blade 27 to rotate at high speed. The first stepper motor 9 is started, and through the lead screw 7 and lead screw bearing 5, it drives the first push plate 6 to move back and forth. The second push plate 38 is driven by the push tube 40, synchronizing with the movement of the first push plate 6. The second push plate 38, through the connecting rod 18, the shift fork seat 19, and the shift fork 42, causes the second slider 22 to move up and down, thereby enabling the cutting blade 27 to open and close for cutting.

[0045] The second stepper motor 11 starts and, through the second gear 13, the first gear 12, and the main shaft 41, drives the rotating base plate 15 to rotate 360 ​​degrees. The cutting blade 27 rotates around the guide tube 28 to perform the first 360-degree cut.

[0046] Furthermore, because the shielding mesh is initially woven and cross-woven, the opening and closing motion of the second parallel gripper cylinder 34 causes the brush 29 to close, forming a closed "○" shape, thus straightening the shielding mesh in the first 360° forward direction. Also, because the front end of the guide tube 28 has a groove 43 along its circumference, the straightened copper wires will get stuck in the groove 43, preventing them from moving left or right. This prevents the cutting blade 27 from causing the copper wires to move left or right due to friction during cutting, thus avoiding the inability to cut the copper wires.

[0047] After the first straightening is completed, the output end of the thin cylinder 39 moves back and forth, driving the second parallel gripper cylinder 34 to move back and forth, thereby driving the second rotary motor 33 and the brush 29 to move back and forth, making room for the cutting blade 27; in preparation for the second cutting.

[0048] The through-type stepper motor 10 starts and drives the first slider 17 to move back and forth via the motor output screw. Since the guide tube 28 is connected to the first slider 17, it also moves back and forth, adjusting the length of the netting.

[0049] After the first cut, use brush 29 to straighten the shielding mesh by rotating it clockwise, and then make a second 360° cut. After the second cut, brush 29 is rotated counterclockwise to flip the shielding mesh back, resulting in a neat cut that will not damage the core wire insulation.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
