Description

Technical Field

[0001] The present invention belongs to the technical field of wire harness terminal processing, and particularly relates to a fully automatic terminal extrusion device. Background Art

[0002] An automotive wire harness is the network main body of an automotive circuit. An automotive wire harness refers to a component formed by crimping contact terminals made of copper material to electric wires and cables, and then externally molding an insulator or adding a metal shell, etc., and bundling the wire harness to form a circuit connection.

[0003] In the actual production process, an automotive wire harness is composed of several wires, and the shielding shells at both ends are usually of different models. For example, one end that needs to be connected to a battery or other integrated modules is of an overall integrated type, while the shielding shell at the other end connected to an electric mechanism or module is of a separate and dispersed type, that is, only one wire can be accommodated in the shielding shell at the other end. The wire harness production line body in the prior art can only extrude and install one type of shielding shell, and the line body that can extrude and install multiple types of shielding shells needs to replace the extrusion mechanism, which will reduce the production efficiency of the automotive wire harness.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Referring to Figures 1 to 5 as shown, the present invention provides a fully automatic terminal extrusion device, including:

[0033] A workbench 1, with support legs 2 respectively arranged at the four corners of the bottom end;

[0034] A conveying mechanism, fixedly arranged at the top end of the workbench 1, and the conveying mechanism is arranged along the length direction of the workbench 1;

[0035] A wire harness coiling mechanism, arranged at the top end of the conveying mechanism, and the wire harness coiling mechanism is used for coiling the wire harness that needs to be subjected to terminal extrusion;

[0036] The terminal extrusion mechanism is arranged at the top of the workbench 1. The terminal extrusion mechanism is arranged in parallel with the conveying mechanism. The terminal extrusion mechanism is used for extruding terminals at both ends of the coiled wire harness.

[0037] Furthermore, the wire harness coiling mechanism includes a wire harness coiling part. The wire harness coiling part is rotatably arranged in the middle of the top of the conveying mechanism. The wire harness coiling part is used for coiling the wire harness that needs to be subjected to terminal extrusion. A first clamping part is rotatably arranged at the top of the conveying mechanism. The first clamping part is coaxially arranged outside the wire harness coiling part. The first clamping part is used for clamping one end of the wire harness. A second clamping part is rotatably arranged at the top of the conveying mechanism. The second clamping part is coaxially arranged outside the first clamping part. The second clamping part is used for clamping the other end of the wire harness. The top of the wire harness coiling part is higher than the top of the second clamping part. The top of the second clamping part is higher than the top of the first clamping part. One end of the wire harness passes through the second clamping part movably and is fixed on the first clamping part. The first clamping part rotates around the wire harness coiling part to wind the wire harness around the wire harness coiling part. The second clamping part fixedly clamps the other end of the wire harness.

[0038] When coiling the wire harness, first, one end of several wires cut according to the designed length passes through the second clamping part and is fixed on the first clamping part. Then, the first clamping part drives one end of the wire to rotate around the wire harness coiling part until the wire is wound around the wire harness coiling part. Then, the second clamping part also fixes the other end of the wire. After that, the conveying mechanism moves to convey the coiled wire to the working position of the terminal extrusion mechanism for extruding the terminal and the shielding shell. The top height of the first clamping part, the top height of the second clamping part, and the top height of the wire harness coiling part increase in sequence. In this way, it can be ensured that the wire will not be entangled and knotted during the process of winding around the wire harness coiling part.

[0039] Furthermore, the wire harness coiling part includes a coiling motor. The coiling motor is fixedly embedded in the conveying mechanism. The output end of the coiling motor is coaxially and fixedly connected to the bottom end of the center table 13. The center table 13 is rotatably connected to the conveying mechanism. Several upright columns 14 are fixedly connected to the top of the center table 13. The several upright columns 14 are arranged vertically and are circumferentially and equally spaced along the outer edge of the top of the center table 13. A limiting part is arranged at the top of each upright column 14.

[0040] When the first clamping part fixes one end of the wire and rotates around the center table 13, the whole wire is wound around the outside of the several upright columns 14 to complete the coiling process. The limiting part at the top of the upright column 14 can prevent the wire from slipping off the top of the upright column 14 during the coiling process of the wire, ensuring the smooth progress of the coiling work.

[0041] Further, the limiting part includes a limiting rod 16. One end of the limiting rod 16 is rotatably connected to the top end of the column 14 through a hinge shaft 15. A torsion spring is arranged on the hinge shaft 15, and the two ends of the torsion spring are respectively fixedly connected to the limiting rod 16 and the column 14.

[0042] During the wire coiling process, the limiting rod 16 remains perpendicular to the column 14 under the elastic force of the torsion spring, so as to ensure that the coiled wire will not slip off from the top end of the column 14. After the terminal and the shielding shell are squeezed, the staff lifts the automotive wire harness upward. During the lifting process, the wire harness overcomes the elastic force of the torsion spring and makes the limiting rod 16 rotate to the vertical state, and then the automotive wire harness can be smoothly removed from the column 14. After the automotive wire harness is removed, under the action of the torsion spring, the limiting rod 16 returns to the state perpendicular to the column 14 again.

[0043] Further, the first clamping part includes a first clamping motor, which is fixedly embedded in the conveying mechanism. The output end of the first clamping motor is coaxially and fixedly connected with a first gear 18. An internal gear ring 17 is coaxially and rotatably connected to the outer side wall of the central platform 13. The internal gear ring 17 meshes with the first gear 18. One end of a first connecting frame 19 is fixedly connected to the outer edge of the top end of the internal gear ring 17. An angle adjusting part is arranged at the top of the other end of the first connecting frame 19. The top end of the angle adjusting part is fixedly connected to a first fixing frame 25. A plurality of first partition plates 29 are fixedly connected inside the first fixing frame 25. The plurality of first partition plates 29 are arranged vertically and at equal intervals. A plurality of first telescopic rods 30 are fixedly connected to the top wall of the first fixing frame 25. The telescopic ends of the first telescopic rods 30 are fixedly connected to a first pressing plate 31. The first pressing plate 31 is slidably arranged between the first partition plates 29 and the inner side wall of the first fixing frame 25 and between two adjacent first partition plates 29.

[0044] The arranged plurality of first telescopic rods 30 and the first pressing plate 31 can squeeze and fix different numbers of wires in the first fixing frame 25, and the end parts of two adjacent wires are separated by the first partition plates 29, which is convenient for subsequent squeezing of the terminal and the shielding shell. After the wires are fixed in the first fixing frame 25, the first clamping motor works to drive the first gear 18 to rotate, and then drives the first fixing frame 25 to rotate around the central platform 13 through the internal gear ring 17. During the rotation process, the wires can be wound around the column 14.

[0045] Further, the angle adjusting part includes a connecting rod 24, which is arranged vertically and the bottom end of which is rotatably connected to the first connecting frame 19. The first fixing frame 25 is fixedly connected to the top end of the connecting rod 24. A third gear ring 28 is fixedly sleeved in the middle of the outer side wall of the connecting rod 24. A third motor 26 is fixedly connected to the top end of the first connecting frame 19. The output shaft of the third motor 26 is coaxially and fixedly connected with a third gear 27. The third gear 27 meshes with the third gear ring 28.

[0046] The connecting rod 24 is used to adjust the rotation angle of the first fixing frame 25 itself, so that the front of the fixed end of the wire faces the terminal pressing mechanism, facilitating the pressing of the terminal and the shielding case.

[0047] Furthermore, the second clamping part includes a second clamping motor which is fixedly embedded in the conveying mechanism. The output end of the second clamping motor is coaxially and fixedly connected with a second gear 21. The top end of the conveying mechanism is rotatably connected with an external gear ring 20. The external gear ring 20 is coaxially arranged outside the internal gear ring 17. The external gear ring 20 meshes with the second gear 21. One end of a second connecting frame 22 is fixedly connected to the outer side wall of the external gear ring 20. The other end of the second connecting frame 22 is fixedly connected to a second fixing frame 23. A double clamping part is arranged inside the second fixing frame 23.

[0048] During the process that the first clamping part drives the wire to wind around the outer side of the column 14, the double clamping part does not act. After the wire winding is completed, the double clamping part acts to clamp and fix the other end of the wire. The double clamping part can clamp and fix the other ends of multiple wires in the same plane, or can clamp and fix the other ends of multiple wires into two vertically arranged rows side by side. The design of the double clamping part can make the device have a wider application range.

[0049] Furthermore, the double clamping part includes a first central plate 32 which is horizontally arranged and fixedly connected to the middle parts of the two opposite inner side walls of the second fixing frame 23. Between the bottom end of the first central plate 32 and the bottom wall of the second fixing frame 23, a plurality of second partition plates 33 are fixedly connected. The plurality of second partition plates 33 are vertically arranged at equal intervals. The bottom end of the first central plate 32 is also fixedly connected with a plurality of second telescopic rods 34. The second telescopic rods 34 are respectively arranged between the second partition plates 33 and the inner side wall of the second fixing frame 23 and between two adjacent second partition plates 33. The telescopic ends of the second telescopic rods 34 are fixedly connected with second pressing plates 35. The second pressing plates 35 are in sliding contact with the side walls of the second partition plates 33 and the inner side wall of the second fixing frame 23.

[0050] Between the top end of the first central plate 32 and the top wall of the second fixing frame 23, two limiting side plates 36 are fixedly connected. The two limiting side plates 36 are vertically arranged at an interval. In the middle between the two limiting side plates 36, a horizontally arranged second central plate 37 is fixedly connected. Between the top end of the second central plate 37 and the top wall of the second fixing frame 23 and between the bottom end of the second central plate 37 and the top end of the first central plate 32, a plurality of third partition plates 38 are fixedly connected. The plurality of third partition plates 38 are arranged at equal intervals. The top end of the first central plate 32 and the top wall of the second fixing frame 23 are both fixedly connected with a plurality of third telescopic rods 39. The third telescopic rods 39 are located between the limiting side plates 36 and the third partition plates 38 and between two adjacent third partition plates 38. The telescopic ends of the third telescopic rods 39 are fixedly connected with third pressing plates 40. The third pressing plates 40 are in sliding contact with the side walls of the limiting side plates 36 and the side walls of the third partition plates 38.

[0051] When the integrated shielding case of the automotive wire harness is in the form of single-row juxtaposition, multiple wires are squeezed and fixed through the second pressing plate 35 and the bottom wall of the second fixing frame 23. When the integrated shielding case is in the form of double-row superposition, multiple wires are fixed respectively through the third pressing plate 40 and the top and bottom ends of the second center plate 37.

[0052] Furthermore, the conveying mechanism includes a first motor 3. The first motor 3 is fixedly connected to one end of the top of the workbench 1. One end of the output shaft of the first motor 3 is coaxially and fixedly connected to one end of a lead screw 4. The lead screw 4 is horizontally arranged and the other end is rotatably connected to a first fixing seat 5. The first fixing seat 5 is fixedly connected to the other end of the top of the workbench 1. A slide table 8 is threadedly connected to one end of the lead screw 4. The bottom end of the slide table 8 is in sliding contact with the top end of the workbench 1. The other end of the slide table 8 slidably penetrates a guide rod 6. The guide rod 6 is parallel to the lead screw 4 and is located on the same horizontal plane. Both ends of the guide rod 6 are respectively fixedly connected to a second fixing seat 7. The second fixing seat 7 is fixedly connected to the top end of the workbench 1. The wire harness coiling mechanism is arranged on the top end of the slide table 8.

[0053] During the process of wire coiling, the slide table 8 is located at the starting position close to the first motor 3. After the wire coiling is completed, the first motor 3 works to drive the lead screw 4 to rotate. During the rotation of the lead screw 4, the slide table 8 and the coiled wire on the slide table 8 are driven to move to the working position of the terminal extrusion mechanism for the extrusion work of the terminal and the shielding case.

[0054] Furthermore, the terminal extrusion mechanism includes three connecting seats 9. The three connecting seats 9 are arranged side by side along the length direction of the workbench 1. A terminal robotic arm 10 is rotatably arranged at the top end of one connecting seat 9. A first shielding case robotic arm 11 is rotatably arranged at the top end of another connecting seat 9. A second shielding case robotic arm 12 is rotatably arranged at the top end of the third connecting seat 9. The terminal robotic arm 10, the first shielding case robotic arm 11, and the second shielding case robotic arm 12 are arranged in sequence.

[0055] The terminal robotic arm 10 performs the clamping and extrusion work of the wire harness terminal. The first shielding case robotic arm 11 performs the clamping and extrusion work of the integrated shielding case. The second shielding case robotic arm 12 performs the clamping and extrusion work of the dispersive shielding case.

[0056] When performing the extrusion work on the terminals, the sliding table 8 moves to the working position of the terminal manipulator 10. The terminal manipulator 10 first grabs the terminal and extrudes the terminal against the end of the wire within the first fixed frame 25. After all the wire ends within the first fixed frame 25 have completed the terminal extrusion, the external gear ring 20 and the second connecting frame 22 drive the second fixed frame 23 to rotate to the working position of the terminal manipulator 10. When the second fixed frame 23 rotates to the working position of the terminal manipulator 10, the end of the wire fixed inside it faces the jaw side of the terminal manipulator 10 to facilitate the terminal manipulator 10 to perform the terminal extrusion work on it. When the external gear ring 20 and the second connecting frame 22 drive the second fixed frame 23 to rotate, the central table 13 and the first fixed frame 25 synchronously drive the coiled wire and the other end of the wire to rotate. This is to facilitate the end of the wire within the second fixed frame 23 to smoothly rotate to the working position of the terminal manipulator 10. If the central table 13 and the first fixed frame 25 do not drive the coiled wire and the other end of the wire to rotate synchronously, the end of the wire within the second fixed frame 23 cannot rotate to the working position of the terminal manipulator 10. After the terminal extrusion is completed at both ends of the wire, the sliding table 8 continues to move to the working positions of the first shielding case manipulator 11 and the second shielding case manipulator 12, and the first shielding case manipulator 11 and the second shielding case manipulator 12 perform the extrusion of shielding cases of different models. During the extrusion of the shielding case, first, the second shielding case manipulator 12 performs the extrusion of the dispersed shielding case. After the extrusion is completed, the second fixed frame 23, the central table 13, and the first fixed frame 25 repeat the rotation action during the terminal extrusion so that the first shielding case manipulator 11 can perform the extrusion of the integrated shielding case on the other end of the wire.

[0057] The working process of the present invention is as follows:

[0058] First, the ends of several wires that make up the automotive wiring harness are simultaneously passed through the second fixed frame 23 and fixed within the first fixed frame 25. After the fixation is completed, the first fixed frame 25 drives the wire to rotate and wind around the column 14. After the winding is completed, the second pressing plate 35 or the third pressing plate 40 fixes the other end of the wire within the second fixed frame 23. Then, the sliding table 8 moves to convey the coiled wire to the working position of the terminal manipulator 10 for terminal extrusion. After the terminal extrusion is completed, the sliding table 8 continues to move to convey the wire to the working positions of the first shielding case manipulator 11 and the second shielding case manipulator 12 for the extrusion of shielding cases of different models. After the shielding case extrusion is completed, the staff removes the processed wiring harness from the column 14, and the sliding table 8 resets and moves to the starting position to perform the terminal extrusion work on the next automotive wiring harness.
