Description

Technical fields:

[0001] This utility model relates to the field of wire (100) processing technology, and specifically to an automatic assembly machine for high-frequency and high-speed connectors. Background technology:

[0002] FAKRA connectors are high-frequency RF connectors designed specifically for automotive electronic systems. Their compact and reliable performance makes them widely used in automotive communication and sensor applications. Featuring a 50Ω impedance design, they support signal transmission up to 6GHz and incorporate a locking mechanism to prevent mis-mating and high-temperature resistance (-40℃ to +105℃), making them suitable for critical systems such as GPS antennas, automotive cameras, and radar. As an industry standard for automotive RF interfaces, FAKRA's superior electrical performance and mechanical stability have made it a core component for signal transmission in intelligent driving and new energy vehicles. Typical products include basic adapters, all-in-one integrated solutions, and matching cables (100), meeting the needs of various scenarios from traditional in-vehicle entertainment to autonomous driving.

[0035] In summary, when this utility model is used, the wire coil is installed into the wire feeding module 21 of the wire feeding mechanism 2, and one end of the wire 100 is passed through the orientation module 28, and then sequentially passes through the wire tensioning module 22, the printing module 23, the turning module 27, the wire assembly module 24, the code reader 26, and the wire cutting module 25. When the length of the wire 100 extending to the clamp 14 reaches the preset value, the wire cutting module 25 cuts the wire 100. Furthermore, the upper material feeding module 15 pushes the clamp 14 to slide along the upper guide rail 12, and sequentially sleeves the wire. The system includes a pre-assembly mechanism 3, a wire stripping mechanism 4, a braiding mechanism 5, a terminal crimping mechanism 6, a vision inspection module 10, a shielded terminal pre-assembly mechanism 7, a shielded terminal crimping mechanism 8, and an inspection and material distribution mechanism 9. Then, the right-side lifting device 18 transfers the clamp 14 from the upper guide rail 12 to the lower guide rail 13. The lower material distribution module 16 pushes the clamp 14 back to the leftmost end along the lower guide rail 13. The left-side lifting device 17 then transfers the clamp 14 back to the upper guide rail 12, allowing the clamp 14 to grab the wire 100 again from the wire feeding mechanism 2. This completes the process. The clamp 14 is used cyclically to achieve continuous processing of the wire 100. Further, the sleeve pre-installation mechanism 3 installs the sleeve onto the wire 100. Since the wire 100 is U-shaped and held by the clamp 14, the sleeve pre-installation mechanism 3 simultaneously installs sleeves on both ends of the wire 100. Further, the wire stripping mechanism 4 removes the outer sheath from the end of the wire 100, and then the braiding mechanism 5 folds the braided layer of the wire 100 backward to facilitate terminal crimping. Further, the terminal crimping mechanism 6 crimps the end of the wire 100... The appropriate terminals are crimped, and then the visual inspection module 10 checks whether the crimping of the terminals meets the requirements. Further, the shielding terminal pre-installation mechanism 7 installs the shielding terminal onto the end of the wire 100, and then the shielding terminal pre-installation mechanism 7 presses the shielding terminal installed on the wire 100 to make the shielding terminal and the wire 100 stably connected. Further, the detection and sorting mechanism 9 checks whether the finished product of the wire 100 after processing meets the requirements, and the good products are removed from the fixture 14, while the defective products are cut off and discharged as waste.

[0036] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
