[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] like Figures 1 to 11 The outer conductor rubber core assembly, riveting and crimping device shown includes: a frame 01, on which a conveying mechanism 1, a pushing mechanism 2, a riveting mechanism 3 and a crimping mechanism 4 are fixed. Figure 1 As shown, the conveying mechanism 1, the pushing mechanism 2, the riveting mechanism 3 and the crimping mechanism 4 are placed in the order of assembling the rubber core 02, the outer conductor 03 and the wiring harness, as shown in FIG. Figure 2 As shown, the rubber core 02 is placed inside the outer conductor 03. When the rubber core 02 and outer conductor 03 wiring harness are assembled, the rubber core 02 and the outer conductor 03 are first transported by the conveying mechanism 1, and the rubber core 02 is pushed into the outer conductor 03 by the pushing mechanism 2. The rubber core 02 and the outer conductor 03 are then crimped by the riveting mechanism 3. Finally, the wiring harness and the rubber core 02 and outer conductor 03 are crimped by the crimping mechanism 4 to complete the assembly of the rubber core 02 and outer conductor 03 wiring harness.

[0046] The pushing mechanism 2 includes a pushing seat 21 for placing the rubber core 02, a push rod 22 for pushing the rubber core 02 into the inner portion of the outer conductor 03, and a first driving component 23 connected to the push rod 22. Figure 3 、 Figure 4As shown, the rubber core 02 is conveyed to the pushing seat 21 through the rubber core 02 conveying component, and the outer conductor 03 is conveyed to one end of the pushing seat 21 through the outer conductor 03 conveying component. The first driving component 23 is used to push the push rod 22, and the push rod 22 pushes the rubber core 02 on the pushing seat 21 into the outer conductor 03, thereby realizing the installation of the rubber core 02 and the outer conductor 03.

[0047] The riveting mechanism 3 includes a sliding platform 31 that can slide relative to the frame 01, a riveting seat 32 fixed on the sliding platform 31, at least one riveting assembly 33 connected to the riveting seat 32, and a second driving assembly 34 fixed on the sliding platform 31 for driving the riveting assembly 33 to fix the rubber core 02 and the outer conductor 03. Figure 5 、 Figure 6 As shown, the sliding platform 31 of the rivet mechanism 3 is set on the frame 01. By driving the sliding platform 31, the rivet seat 32 and the rivet assembly 33 move toward the assembled rubber core 02 and the outer conductor 03. It should be pointed out here that there are many ways for the sliding platform 31 to slide, which can be through the slider 31a1 and the slide rail 31a2, through the screw and the slider 31a1, or other structures that can make the sliding platform 31 slide. Figure 5 、 Figure 6 As shown, the rivet point seat 32 is used to place the installed rubber core 02 and outer conductor 03, and the rivet point assembly 33 on the rivet point seat 32 is used to fix the rubber core 02 and the outer conductor 03.

[0048] The conveying mechanism 1 includes a rubber core 02 conveying component and an outer conductor 03 conveying component. The output end 11a of the rubber core 02 conveying component is connected to the pusher seat 21, and the output line 12a of the outer conductor 03 conveying component is set on the side of the rivet point seat 32 away from the first drive component 23. Figure 1 、 Figure 3 、 Figure 5 As shown, the outer conductor 03 conveying assembly conveys the outer conductor 03 to one side of the pushing mechanism 2 and the riveting mechanism 3. The output line 12a of the outer conductor 03 conveying assembly has a row of outer conductors 03. The installation and riveting of the outer conductor 03 and the rubber core 02 are realized by connecting the outer conductors 03 side by side. The output end 11a of the rubber core 02 conveying assembly conveys the rubber core 02 to the pushing seat 21.

[0049] The crimping mechanism 4 includes a clamping claw 41 for fixing the wire harness, a crimping seat 42 for placing the outer conductor 03 of the rubber core 02, and a pressing head 43 that can move closer to or farther away from the crimping seat 42. Figure 11 As shown, the wire harness is clamped by the clamping claw 41, and the rubber core 02 and the outer conductor 03 after the riveting points are combined are placed on the crimping seat 42, one end of the wire harness is inserted into the rubber core 02, and finally the wire harness and the outer conductor 03 of the rubber core 02 are crimped by the pressing head 43 to realize the assembly of the wire harness and the outer conductor 03 of the rubber core 02.

[0050] The present invention uses the rubber core 02 conveying component to convey the rubber core 02 to the pushing seat 21, and conveys the outer conductor 03 to one side of the rivet point seat 32 through the outer conductor 03 conveying component. First, the rubber core 02 is pushed into the inner part of the outer conductor 03 by the push rod 22, and then the outer conductor 03 with the rubber core 02 is conveyed to the rivet point seat 32 station through the output line 12a of the outer conductor 03 conveying component. The sliding seat is driven to slide toward the rivet point seat 32, so that the rubber core 02 and the outer conductor 03 extend into the accommodating chamber 32b of the rivet point seat 32, and the second driving component 34 is driven. The driving block 34b on the upper portion drives the rivet point assembly 33, so that the rivet point assembly 33 fixes the rubber core 02 and the outer conductor 03, and then drives the sliding platform 31 away from the rivet point seat 32. The outer conductor 03 conveying assembly continues to move, and the outer conductor 03 of the rubber core 02 is transferred to the crimping seat 42 of the crimping mechanism 4. The clamping claw 41 clamps the wire harness and extends into the inner part of the outer conductor 03 of the rubber core 02. The pressing head 43 fixes the outer conductor 03 of the rubber core 02 and the wire harness. In this way, the outer conductor 03 of the rubber core 02 is fixed by riveting points, and the wire harness and the outer conductor 03 of the rubber core 02 are crimped and fixed in a cycle.

[0051] In some embodiments of the present invention, a rivet hole 32a is provided at one end of the rivet seat 32 facing the rubber core 02 delivery assembly. The rivet hole 32a contains a receiving chamber 32b for receiving the outer conductor 03 of the rubber core 02. At least one through hole 32c perpendicular to the extending direction of the receiving chamber 32b is provided on the side wall of the rivet seat 32. The rivet assembly 33 can be relatively movably arranged in the through hole 32c. Figures 6 to 8 As shown, the accommodating chamber 32b in the rivet hole 32a is used for inserting the rubber core 02 and the outer conductor 03 after installation. At the same time, the through hole 32c on the side wall of the rivet seat 32 is used for inserting the rivet assembly 33. The rivet assembly 33 extends into the accommodating chamber 32b to fix the rubber core 02 and the outer conductor 03.

[0052] In some embodiments of the present invention, the rivet assembly 33 includes a fixed block 33a fixed to the rivet seat 32, a connecting arm 33c rotatably connected to the fixed block 33a via a first rotating shaft 33e33b, and a T-shaped rivet member 33f rotatably connected to one end of the connecting arm 33c via a second rotating shaft 33e33d. The T-shaped rivet member 33f can move through the through hole 32c. Figure 9 As shown, the rivet point assembly 33 is arranged on the outer wall of the rivet point seat 32, and is fixed to the rivet point seat 32 through the fixing block 33a. At the same time, the rubber core 02 and the outer conductor 03 are riveted by the lever principle. A connecting arm 33c is rotatably connected to the fixing block 33a, and one end of the connecting arm 33c has a T-shaped rivet point part 33f. The T-shaped rivet point part 33f extends into the interior of the through hole 32c, and the end of the T-shaped rivet point part 33f extends into the accommodating chamber 32b. The rubber core 02 and the outer conductor 03 are fixed by riveting through the end of the T-shaped rivet point part 33f.

[0053] Through the above arrangement of the rivet point assembly 33, the other end of the connecting arm 33c close to the second driving assembly 34 is further provided with a rotating shaft 33e, which is rotatably connected. The rotating shaft 33e can slide relatively on the second driving assembly 34. Figures 7 to 9 As shown, the other end of connecting arm 33c contacts second drive assembly 34, which drives rivet assembly 33 to rivet rubber core 02 and outer conductor 03. A rotating shaft 33e is rotatably connected to the other end of connecting arm 33c. The second drive assembly 34 drives the rotating shaft 33e to rotate, thereby driving the displacement of connecting arm 33c. The provision of rotating shaft 33e reduces wear on rivet assembly 33 during operation, thereby increasing its service life.

[0054] By setting the T-shaped rivet point member 33f as above, the T-shaped rivet point member 33f can fix the rubber core 02 and the outer conductor 03 more firmly. Figure 9 、 Figure 10 As shown, the T-shaped rivet assembly 33f includes an extension plate 33f1 connected to the second rotating shafts 33e and 33d, a connecting rod 33f2 connected to the extension plate 33f1 and extending into the through hole 32c, and a conical rivet head 33f3 connected to the connecting rod 33f2 and coaxially arranged. The extension plate 33f1 is positioned at the end of the through hole 32c away from the accommodating chamber 32b. The connecting rod 33f2 and the conical rivet head 33f3 extend through the through hole 32c into the accommodating space. The conical rivet seat 32 is positioned within the accommodating chamber 32b. The end of the conical rivet head 33f3 rivets the rubber core 02 and the outer conductor 03. The outer conductor 03 is made of metal. Pressure is applied to the rivet assembly 33, which drives the conical rivet head 33f3 to press against the outer conductor 03, thereby securing the rubber core 02 and the outer conductor 03.

[0055] In order to make the T-shaped rivet point member 33f return to its original position better after riveting, Figure 10 As shown, an elastic member 33g is sleeved over the T-shaped rivet assembly 33f. One end of the elastic member 33g abuts against the extension plate 33f1, while the other end is fixedly connected to the inner wall of the through-hole 32c. When pressure is applied to the rivet assembly 33, the elastic member 33g compresses, causing the tapered rivet head 33f3 to rivet the rubber core 02 and the outer conductor 03. When the pressure is released, the elastic force of the elastic member 33g returns the T-shaped rivet head to its initial position.

[0056] In some embodiments of the present invention, the second driving assembly 34 includes a motor 34a, a driving block 34b fixedly connected to the motor 34a, and a cross-sectional area of ​​the driving block 34b from the direction close to the rivet point seat 32 to the cross-sectional area of ​​the end away from the driving block 34b gradually increases. The rivet point assembly 33 can be relatively slidably arranged on the driving block 34b. Figures 5 to 9As shown, the driving block 34b is driven by the motor 34a, and the cross-sectional area of ​​the driving block 34b gradually increases to promote the movement of the rivet point assembly 33. When the driving block 34b moves toward the rivet point assembly 33, the cross-sectional area of ​​the driving block 34b gradually increases, and one end of the connecting arm 33c of the rivet point assembly 33 is lifted, so that the T-shaped rivet point part 33f at the other end moves toward the accommodating chamber 32b, and the rubber core 02 and the outer conductor 03 are crimped.

[0057] In some embodiments of the present invention, a sliding assembly 31a is further provided between the sliding platform 31 and the rack 01. The sliding assembly 31a includes a slider 31a1 fixed on the end surface of the sliding platform 31 facing the rack 01, a slide rail 31a2 fixed on the end surface of the rack 01 facing the sliding platform 31, and a third driving assembly 31a3 for driving the sliding platform 31 to slide. The slider 31a1 can be relatively slidably arranged on the slide rail 31a2. The driving direction of the second driving assembly 34 is the same as that of the third driving assembly 31a3. Figure 5 、 Figure 6 As shown, the sliding platform 31 slides through the slider 31a1 fixed on the sliding platform 31 and the slide rail 31a2 on the frame 01, and at the same time, the sliding platform 31 is driven by the third driving component 31a3 to move closer to or away from the outer conductor 03 of the rubber core 02, so that the outer conductor 03 of the rubber core 02 extends into the accommodating chamber 32b or moves away from the accommodating chamber 32b.

[0058] In order to make the position of the rubber core 02 extending into the outer conductor 03 more accurate, Figure 3 、 Figure 4 As shown, the pusher seat 21 also has a core 02 groove for placing the core 02. The push rod 22 is relatively movable within the core 02 groove. The core 02 groove is connected to the output end 11a of the core 02 conveying assembly. The core 02 conveying assembly conveys the core 02 into the core 02 groove, and then the push rod 22 conveys the core 02 into the outer conductor 03.

[0059] According to the second aspect of the present invention, a method for assembling, riveting and crimping an outer conductor rubber core is also provided. Figure 12 As shown in , the following steps are included:

[0060] S10: Use the rubber core 02 conveying component to convey the rubber core 02 to the rubber core 02 groove of the pushing seat 21, and use the conveying line of the outer conductor 03 conveying component to convey the outer conductor 03 to one side of the rivet point seat 32;

[0061] S20: The first driving assembly 23 drives the push rod 22 to push the rubber core 02 in the rubber core 02 groove into the inner portion of the outer conductor 03;

[0062] S30: The outer conductor 03 of the rubber core 02 is moved to the operating position of the rivet point seat 32 through the output line 12a of the outer conductor 03 conveying assembly;

[0063] S40: driving the third driving assembly 31a3 to drive the sliding platform 31 to move toward the outer conductor 03 of the rubber core 02, so that the outer conductor 03 of the rubber core 02 extends into the interior of the accommodating chamber 32b;

[0064] S50: Drive the second driving assembly 34 to drive the driving block 34b to move toward the rivet seat 32, and use the driving block 34b to push the rivet assembly 33, so that the conical rivet head 33f3 rivets the rubber core 02 and the outer conductor 03;

[0065] S60: Return the sliding platform 31 to a position away from the rivet point seat 32, and move the outer conductor 03 of the rubber core 02 to the crimping seat 42;

[0066] S70: The clamping claw 41 clamps the wire harness and extends one end of the wire harness into the rubber core 02. The pressing head 43 crimps the wire harness and the outer conductor 03 of the rubber core 02. In this way, the wire harness of the outer conductor 03 of the rubber core 02 is riveted and crimped in a cycle.

[0067] In the specific implementation process of the outer conductor rubber core assembly, riveting and crimping device of the present invention, the rubber core 02 is first transported to the rubber core 02 groove by the rubber core 02 transport component, and the outer conductor 03 is transported to one side of the pushing mechanism 2 and the riveting mechanism 3 by the outer conductor 03 transport component. The outer conductor 03 is docked with the rubber core 02 groove, and the rubber core 02 is transported to the inside of the outer conductor 03 by the first driving component 23. The outer conductor 03 with the rubber core 02 is transported to the work station of the riveting mechanism 3, and the third driving component 31a3 drives the sliding platform 31 to move toward the outer conductor 03 of the rubber core 02, and the outer conductor 03 of the rubber core 02 extends into the accommodating chamber 32b of the riveting seat 32. The second driving component 34 drives the driving block 34b to push the riveting component 33, and the roller on the riveting component 33 rolls to drive the displacement of the connecting arm 33c. The T-shaped rivet piece 33f at the other end moves toward the inside of the accommodating chamber 32b, and the conical rivet head 33f3 at the end of the T-shaped rivet piece 33f rivets the outer conductor 03, so that the rubber core 02 and the outer conductor 03 are fixed. The second drive component 34 drives the drive block 34b to restore the initial position, and the elastic component 33g inside the through hole 32c drives the T-shaped rivet piece 33f to restore the initial position. The third drive component 31a3 drives the sliding table 31 to restore the initial position. Finally, the outer conductor 03 of the rubber core 02 fixed by the riveting point is transferred to the crimping mechanism 4, and the wiring harness is clamped by the clamping claw 41, and the outer conductor 03 of the rubber core 02 is fixed to the wiring harness by the pressing head 43. This cycle is used to realize the rivet point fixation of the outer conductor 03 of the rubber core 02 and the assembly of the wiring harness and the outer conductor 03 of the rubber core 02, thereby realizing automated production to improve production efficiency and qualified quality.
