Description

Technical Field

[0001] The invention relates to the field of automobile wiring harness crimping, and in particular to a fully automatic crimping device for automobile wiring harness terminals. Background Art

[0002] The fully automatic crimping device for automotive wiring harness terminals is a highly automated professional equipment used to accurately and efficiently complete the crimping connection between wires and terminals during the automotive wiring harness manufacturing process. The device realizes full-process operations such as automatic wire feeding, stripping, terminal feeding, positioning, crimping and quality inspection through the coordinated work of precision machinery, electrical control and sensor detection systems. Its core functions include: precise cutting and stripping of cable insulation, automatic sorting and conveying of terminals of different specifications, and use of servo-driven high-precision crimping dies to complete cold-pressed connections. It also integrates quality control measures such as pressure monitoring, optical inspection or tensile testing. Compared with manual or semi-automatic equipment, the fully automatic crimping device can significantly improve production efficiency, ensure consistency and reduce defective rates.

DETAILED DESCRIPTION

[0026] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0027] Example 1:

[0028] like Figures 1 to 3 As shown, the present invention provides a fully automatic crimping device for automobile wiring harness terminals, comprising a crimping device body 1, on which a bottom plate 2 and a frame 3 are provided, and further comprising:

[0029] A driving assembly is provided on the crimping device body 1, and an output end of the driving assembly is connected to the moving assembly. The driving assembly drives the moving assembly to move along the upper surface of the bottom plate 2 of the crimping device body 1;

[0030] A lifting assembly is provided on the moving assembly, a lifting plate 4 is connected to the lifting assembly, and the lifting assembly drives the lifting plate 4 to move in the vertical direction;

[0031] The conversion assembly is arranged on the lifting plate 4, and is provided with a crimping head 5 of different shapes. The conversion assembly drives the crimping head 5 to be replaced to adapt to the wiring harness terminals of different shapes;

[0032] A locking assembly is provided on the lifting plate 4. A locking block 6 is provided on the locking assembly. The locking assembly drives the locking block 6 to move to lock or unlock the crimping head 5.

[0033] The crimping assembly is arranged on the crimping device body 1, and the crimping assembly is located above the conversion assembly. The crimping assembly is provided with abutment joints 7 of different shapes. The abutment joints 7 on the crimping assembly and the crimping joints 5 on the conversion assembly correspond to each other and are adapted to each other. The crimping assembly drives the abutment joints 7 and the crimping joints 5 to press against each other.

[0034] During use, the driving component drives the moving component to move horizontally on the base plate 2, accurately positioning the crimping mechanism to the position requiring processing. Then, the lifting component controls the lifting plate 4 to move up and down, and adjusts the height of the crimping head 5 to adapt to wire harness terminals of different specifications. The crimping heads 5 of different shapes are quickly switched through the conversion component, and the locking component is used to automatically fix or release the crimping head 5 to ensure that the crimping process is stable and reliable. The upper crimping component will drive the corresponding abutting head 7 to press down, and cooperate closely with the lower crimping head 5 to complete the crimping forming of the terminal.

[0035] Example 2:

[0036] like Figures 1 to 3As shown, in combination with the technical solution of Example 1, in this technical solution, the drive assembly includes a first motor 8, which is fixedly mounted on the base plate 2. A first screw 9 is fixedly mounted on the output end of the first motor 8. When the motor is working, it drives the screw to rotate, and the rotation of the screw drives the movement of other components.

[0037] Furthermore, the moving assembly includes a moving plate 10, and a guide rail 11 is provided on the base plate 2. The moving plate 10 is slidably connected to the guide rail 11. The side wall of the moving plate 10 has a threaded hole, and the first screw 9 is threadedly connected to the threaded hole in the moving plate 10. The guide rail 11 is installed on the base plate 2, and the moving plate 10 can slide along the guide rail 11. The threaded hole on the side of the moving plate 10 engages with the screw of the drive assembly. When the screw rotates, it drives the moving plate 10 to move smoothly back and forth along the guide rail 11, so that the crimping device can be accurately delivered to the required working position.

[0038] Furthermore, the lifting assembly includes a second motor 12, which is fixedly mounted on one side of the upper surface of the movable plate 10. A second screw 13 is fixedly mounted on the output end of the second motor 12, and the lifting plate 4 is threadedly connected to the second screw 13. A guide rod 14 is fixedly mounted on the other side of the upper surface of the movable plate 10 and is slidably connected to the movable plate 10. When the motor is started, the screw rotates, driving the lifting plate 4 up and down. To ensure a smooth and stable lifting process, a guide rod 14 is installed next to it, allowing the lifting plate 4 to rise and fall steadily along the guide rod 14.

[0039] Furthermore, the conversion assembly includes a mounting plate 15 and a third motor 16. The upper and lower surfaces of the mounting plate 15 are respectively fixedly mounted with press-fitting heads 5 of different shapes. A mounting hole 17 is provided at the center of the lifting plate 4. Rotating plates 18 are rotatably mounted on the opposite side walls within the mounting hole 17. The two ends of the mounting plate 15 are respectively fixedly connected to the two rotating plates 18. The third motor 16 is fixedly mounted on the side walls of the lifting plate 4. A rotating shaft 19 is fixedly mounted on the output end of the third motor 16. The rotating shaft 19 passes through the side walls of the lifting plate 4 and is fixedly connected to one of the rotating plates 18. When the mold needs to be changed, the third motor 16 will drive the rotating shaft 19 to rotate, and the entire mounting plate 15 will be flipped 180 degrees through the rotating plate 18, so that the press-fitting head 5 on the other side can be quickly switched to use.

[0040] Furthermore, the locking assembly includes two electrically operated telescopic rods 20. Receiving spaces are defined on the inner walls opposite the mounting hole 17. Locking blocks 6 are slidably mounted within each receiving space. One end of each electrically operated telescopic rod 20 is fixedly connected to the bottom walls of each receiving space, while the telescopic ends of each electrically operated telescopic rod 20 are fixedly connected to the two locking blocks 6. When the crimping head 5 needs to be secured, the two electrically operated telescopic rods 20 simultaneously extend the locking blocks 6, firmly engaging the mounting plate 15. To change the mold, the telescopic rods retract the locking blocks 6, releasing the mounting plate 15 and allowing it to rotate freely.

[0041] Furthermore, the crimping assembly includes a hydraulic rod 21, on which a hydraulic head 22 is fixedly mounted. Slideways 23 are fixedly mounted on opposite sides of the frame 3. The hydraulic head 22 is slidably connected to the slideways 23. Two abutment heads 7 of different shapes are fixedly mounted on the lower surface of the hydraulic head 22. When the terminal is to be crimped, the hydraulic rod 21 pushes the hydraulic head 22 downward quickly, allowing the abutment head 7 to mate with the crimping head 5 selected by the conversion assembly below. The corresponding mold is matched to the terminal of different shapes, which not only ensures the crimping quality but also improves work efficiency.

[0042] Furthermore, the abutment 7 is M-shaped or circular. During the crimping process, the hydraulic head 22 precisely presses down the selected abutment 7, engaging the corresponding crimping head 5 of the conversion assembly below. This dual-mode design allows the device to intelligently adapt to most common terminal types.

[0043] Furthermore, both the abutment head 7 and the crimping head 5 are made of phosphor bronze. Phosphor bronze has excellent elasticity and wear resistance. When the upper and lower dies repeatedly crimp the terminals, it will not easily deform, ensuring precise and consistent crimping force each time. Furthermore, this material has good electrical conductivity and can prevent static electricity during the crimping process, making it particularly suitable for processing precision electronic wiring harnesses.

[0044] Working principle of the fully automatic crimping device for automobile wiring harness terminals in this application:

[0045] During use, the driving motor at the bottom drives the moving plate 10 to slide horizontally along the guide rail 11 through the screw, and the lifting motor on the moving plate 10 controls the lifting plate 4 to move up and down through another screw. The conversion mechanism installed on the lifting plate 4 can control the mounting plate 15 to flip 180 degrees. The third motor 16 drives the crimping joints 5 of different shapes on the upper and lower sides to be quickly switched, and the locking blocks 6 controlled by the electric telescopic rods 20 on both sides are firmly fixed. When crimping is required, the hydraulic rod 21 above will drive the matching abutment joint 7 to press down, and accurately cooperate with the crimping joint 5 selected below to complete the crimping.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, use the above technical content to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any changes, modifications, equivalent changes and modifications made to the above embodiments based on the technology of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the present technical solution.
