[0002] With the development of science and technology, wire harnesses play an indispensable role in some important technical fields, such as aircraft, rail passenger cars, weapons and equipment processing and assembly fields. No matter in which equipment, electrical circuits are everywhere. Therefore, for these devices, good wiring is a very important part of the equipment equipment process. While ensuring the smooth flow of electrical circuits, it effectively guarantees the integrity, safety and reliability of the entire system. Therefore, the binding quality of the wire harness is particularly important in the wire harness assembly of the equipment.

Manual operation is not only cumbersome, but also has low operating efficiency and high labor costs. A few automatic binding processing equipment still have problems such as entanglement, feed jamming and bundling failure. For this reason, a wire harness binding machine is proposed.

[0037] The wire clamping mechanism is used to clamp the wire ends of the tying wire on the tying wire shaft 14 and adjust the direction and tie the tying wire by pulling the wire ends. Figure 7As shown, the wire clamping mechanism includes two horizontally arranged wire clamping X-axis linear guide rail groups 15 fixedly mounted on the top of the machine base 1. In this embodiment, the linear guide rail groups all include fixed linear guide rails and movable electric slides. Taking the wire clamping X-axis linear guide rail group 15 as an example, a wire clamping machine 16 is fixedly mounted on two electric slides, and the electric slide drives the wire clamping machine 16 to move along the guide rails in the X-axis direction. The two wire clamping X-axis linear guide rail groups 15 are parallel to each other, and the top drives of the two wire clamping X-axis linear guide rail groups 15 are installed with the same wire clamping machine 16. The top of the wire clamping machine 16 is fixedly installed with a horizontally arranged wire clamping Y-axis linear guide rail group 17, and the wire clamping Y-axis linear guide rail group 17 is perpendicular to the two wire clamping X-axis linear guide rail groups 15. The top drive of the wire clamping Y-axis linear guide rail group 17 is installed with a wire clamping assembly base 18, and the top of the wire clamping assembly base 18 is fixedly installed with a pneumatic clamping jaw 19 and a wire clamping cylinder 20, and the pneumatic clamping jaw 19 is drivingly connected to the wire clamping cylinder 20;

[0038] The wire pulling mechanism is used to pull the binding wire so that the binding wire forms a coil on one side of the wire harness. Figure 2 As shown, the wire drawing mechanism includes a wire drawing machine 21 fixedly mounted on the top of the machine base 1, the wire clamping machine 16 and the wire drawing machine 21 are respectively located on both sides of the winding installation plate 5, the winding motor 6 and the wire drawing machine 21 are located on the same side, and the binding reel 14 and the wire clamping machine 16 are located on the same side. Figure 8 , Fig. 9As shown, the wire drawing machine 21 is fixedly installed with a horizontally arranged first wire drawing linear guide group 22, the first wire drawing linear guide group 22 is parallel to the wire clamping X-axis linear guide group 15, the top drive of the first wire drawing linear guide group 22 is installed with a wire drawing hook cantilever 23, the top side of the wire drawing hook cantilever 23 is fixedly installed with a downwardly arranged first wire drawing hook 24, the top of the wire drawing machine 21 is fixedly installed with a second wire drawing linear guide group 25 parallel to the first wire drawing linear guide group 22, the top drive of the second wire drawing linear guide group 25 is installed with a moving block 26, the top of the moving block 26 is provided with three telescopic slots 2601, two of which are close to the first wire drawing hook 24. The insides of the telescopic slots 2601 are provided with wire tensioning columns 27, and the remaining telescopic slots 260 1 is provided with a second wire-pulling hook 28 inside, and two wire-pulling cylinders are provided inside the moving block 26, and the two wire-pulling cylinders are respectively connected to the wire-tensioning column 27 and the second wire-pulling hook 28 for driving. In this embodiment, the bottom end of the first wire-pulling hook 24 and the side of the second wire-pulling hook 28 facing the tying wire are both provided with a semicircular shape structure, so that when the first wire-pulling hook 24 and the second wire-pulling hook 28 move toward the tying wire, after contacting the tying wire, the tying wire will slide to one side along the semicircular edge of the first wire-pulling hook 24 and the second wire-pulling hook 28, and will not drive the tying wire to move. When the first wire-pulling hook 24 and the second wire-pulling hook 28 return, their straight edges will contact the tying wire and hook the tying wire, thereby pulling the tying wire; specifically, when the wire harness tying machine is in use, first start The wire clamping mechanism makes the wire clamping X-axis linear guide group 15 cooperate with the wire clamping Y-axis linear guide group 17 to drive the wire clamping assembly base 18 to move in two directions, so that the pneumatic clamping claw 19 moves to one side of the tying wire head on the tying wire shaft 14, and then the wire clamping cylinder 20 drives the pneumatic clamping claw 19 to clamp the wire head, and then the staff puts the wire harness to be bundled into the inside of the machine housing 2 through the gap between the flip control console 3 and one side of the machine housing 2, so that the wire harness is inserted into the notch at the axis position of the C-shaped gear disk 12, and then the wire pulling mechanism is started again, so that the first wire pulling linear guide group 22 drives the wire pulling hook cantilever 23 to carry the first wire pulling hook 24 to move toward the wire harness, and the semicircular edge at the bottom end of the first wire pulling hook 24 squeezes the tying wire, so that the first wire pulling hook 24 can move to one side of the tying wire. Then, on the return journey, the straight edge of the first wire pulling hook 24 will hook the tying wire between the tying wire shaft 14 and the pneumatic clamp 19, so that the tying wire shaft 14, the first wire pulling linear guide group 22 and the pneumatic clamp 19 pull the tying wire at three points, thereby driving the tying wire to pass through the gap at the axis position of the C-shaped toothed disc 12 and form a U-shaped coil on one side of the wire harness. Then, the first wire pulling cylinder inside the moving block 26 controls the two wire tensioning columns 27 to pop out from the telescopic groove 2601 into the U-shaped coil surrounded by the tying wire. Then, the first wire pulling linear guide group 22 drives the first wire pulling hook 24 to move toward the wire harness again, so that the coil is separated from the first wire pulling hook 24 and becomes loose, so that the coil falls on the top of the moving block 26, and then the first wire pulling hook 24 returns again.At this time, the height of the coil is lower than the height of the bottom end of the first wire hook 24, so that the first wire hook 24 returns to the initial position without contacting the coil, and then the winding mechanism is started, the winding motor 6 drives the synchronous shaft 7 to rotate through the synchronous belt pulley group 8, and the synchronous shaft 7 drives the C-shaped toothed disc 12 to start rotating through the meshing synchronous gear 9 and the transmission gear 10, and then drives the tying wire mounting seat 13 and the tying wire shaft 14, that is, one end of the tying wire starts to rotate, so that the tying wire is wound around the wire harness for a specified number of turns, and the U-shaped coil is wound around the wire harness during the tying wire winding action. Under the influence of the second wire-pulling hook 28, it gradually moves upward along the wire-pulling column 27 and is tightened on the two wire-pulling columns 27. The second wire-pulling cylinder inside the moving block 26 controls the second wire-pulling hook 28 to pop out. The second wire-pulling linear guide group 25 drives the moving block 26 to move toward the wire harness, so that the semicircular edge of the second wire-pulling hook 28 squeezes the tying wire, thereby moving the second wire-pulling hook 28 to one side of the tying wire between the tying wire shaft 14 and the wire harness. When the second wire-pulling hook 28 returns, the straight edge of the second wire-pulling hook 28 will contact the tying wire between the tying wire shaft 14 and the wire harness and pull it. Then the second wire-pulling hook 28 is retracted into the telescopic groove 2601, so that the binding wire is flattened on the top of the moving block 26. At this time, there is a height difference between the binding wire on the second wire-pulling hook 28 and the coil on the moving block 26, so that the binding wire pulled by the second wire-pulling hook 28 passes through the tightened coil on the wire-tensioning post 27. At this time, the moving block 26 moves a short distance toward the wire harness for the second time, so that the coil is relaxed on the two wire-tensioning posts 27, and then the wire-tensioning posts 27 are retracted into the telescopic groove 2601, so that the coil is completely separated from the wire-tensioning posts 27, and finally the pneumatic clamp 1 9 moves the wire head carrying the binding wire, so that the U-shaped coil is tightened on the wire harness under the drive of the wire head, so that the binding wire pulled back by the second wire hook 28 is knotted with the coil. The binding machine is equipped with a winding mechanism, a clamping mechanism and a pulling mechanism to cooperate with each other, so that the entire process of wire harness binding is automatically carried out. The staff only needs to manually send the wire harness into the designated position inside the binding machine. The equipment has a high degree of automation, simple operation, short process, fast operation, and solves the problems of easy entanglement, feeding jam and bundling failure in the current wire harness binding equipment.

[0039] like Figure 3 As shown, a cutting cylinder 29 is fixedly installed on the side of the wire winding mounting plate 5 away from the tying wire shaft 14, and a knife seat 30 is driven to be installed on the output end of the cutting cylinder 29. The knife seat 30 is slidably installed on one side of the wire winding mounting plate 5, and a cutting knife 31 is fixedly installed on the bottom of the knife seat 30; specifically, when the tying wire pulled back by the second wire pulling hook 28 is knotted with the coil, the cutting cylinder 29 drives the cutting knife 31 to descend through the knife seat 30, cuts off the tying wire on the second wire pulling hook 28, and the second wire pulling hook 28 pops out to loosen the tying wire, and each workstation returns to its initial position, thereby completing the automatic bundling of the wire harness and realizing the automatic cutting of the tying wire.

[0040] like Figure 4 , Figure 6As shown, a plurality of evenly distributed outer positioning wheels 32 are rotatably installed on one side of the winding installation plate 5, and the plurality of outer positioning wheels 32 are respectively in contact with the outer ring of the C-shaped rotating ring 11, and a plurality of evenly distributed inner positioning wheels 33 are rotatably installed on one side of the winding installation plate 5, and the plurality of inner positioning wheels 33 are respectively in contact with the inner ring of the C-shaped rotating ring 11. In this embodiment, the inner ring and the outer ring of the C-shaped rotating ring 11 are both V-shaped structures protruding outward, and the outer positioning wheels 32 and the inner positioning wheels 33 are both V-shaped structures recessed inward, and the outer positioning wheels 32 and the inner positioning wheels 33 are respectively in contact with the outer ring and the inner ring of the C-shaped rotating ring 11; specifically, By setting the outer positioning wheel 32 and the inner positioning wheel 33, the evenly distributed multiple outer positioning wheels 32 and inner positioning wheels 33 can respectively position the C-shaped swivel 11 from the outer ring and the inner ring of the C-shaped swivel 11, so that the C-shaped swivel 11 is rotatably suspended on one side of the winding mounting plate 5. When the winding motor 6 drives the C-shaped toothed disc 12 to rotate through the gear set, the C-shaped swivel 11 rotates synchronously between the multiple outer positioning wheels 32 and the multiple inner positioning wheels 33, thereby ensuring the smooth operation of the C-shaped swivel 11 and the C-shaped toothed disc 12, and at the same time ensuring that the notch of the C-shaped toothed disc 12 for placing the wiring harness will not affect the rotation of the C-shaped toothed disc 12.

[0041] like Figure 5 As shown, both ends of the tying wire shaft 14 are rotatably installed with hanging rotating rods 34, and the ends of the two hanging rotating rods 34 that are far away from each other are respectively in contact with the side walls of the tying wire mounting seat 13, and both sides of the tying wire mounting seat 13 are provided with locking threaded holes, and the locking threaded holes are screwed with threaded locking rods 35. The ends of the two threaded locking rods 35 that are close to each other are in contact with the hanging rotating rods 34, and the other ends of the threaded locking rods 35 are fixedly installed with control screw caps 36; specifically, by setting the threaded locking holes The positioning rod 35 allows the tying wire spool 14 to be installed on the tying wire mounting seat 13 through the hanging rotating rods 34 at both ends, so that the tying wire spool 14 can be pulled by the tying wire head on the tying wire mounting seat 13 and release the wire by itself. When the tying wire is used up, the staff can unscrew the control screw cap 36 from the tying wire mounting seat 13 to release the limit on the tying wire spool 14, remove the tying wire spool 14 for replacement, and then re-screw the threaded positioning rod 35 to complete the quick replacement of the tying wire spool 14.

[0042] like Fig. 9 As shown, the top of the wire-tensioning post 27 is provided with a wire-binding groove 2701; specifically, by providing the wire-binding groove 2701, when the U-shaped coil is gradually tightened due to the action of the wire clamping mechanism and is finally tightened on the two wire-tensioning posts 27, the wire-binding groove 2701 opened at the top of the wire-tensioning post 27 will clamp the coil inside, thereby preventing the coil from directly slipping off the top of the wire-tensioning post 27 due to the pulling of the wire clamping mechanism, resulting in the inability to automatically tie the subsequent binding wire.

[0043] like Figure 1As shown, a wire-changing opening and closing plate 37 is rotatably installed on the top of the flip control console 3, and the position of the wire-changing opening and closing plate 37 corresponds to the position of the bundling wire reel 14; specifically, by setting the wire-changing opening and closing plate 37, the wire-changing opening and closing plate 37 corresponding to the position of the bundling wire reel 14 can facilitate the staff to open the channel connected to the inside of the machine shell 2 from the outside without opening the flip control console 3, and then replace the internal bundling wire reel 14.

[0044] like Figure 1 As shown, a heat dissipation fan 38 is fixedly installed on one side of the machine housing 2; specifically, by setting the heat dissipation fan 38, during the automatic operation of various mechanisms inside the wire harness binding machine, the heat dissipation fan 38 can blow air to cool down various components inside the machine housing 2 and the flip console 3, thereby ensuring that the operating temperature of the binding machine is within the normal threshold.

[0045] In summary: The steps for using the wire harness binding machine are as follows:

[0046] Wire end clamping: first start the wire clamping mechanism, so that the wire clamping X-axis linear guide rail group 15 cooperates with the wire clamping Y-axis linear guide rail group 17 to drive the wire clamping assembly base 18 to move in two directions, so that the pneumatic clamping claw 19 moves to one side of the tying wire end on the tying wire shaft 14, and then the wire clamping cylinder 20 drives the pneumatic clamping claw 19 to clamp the wire end;

[0047] Inserting the wire harness: The staff puts the wire harness to be bundled into the machine housing 2 through the gap between the flip console 3 and one side of the machine housing 2, so that the wire harness is inserted into the gap at the axis position of the C-shaped gear disc 12;

[0048] Generating coil: Start the wire pulling mechanism, so that the first wire pulling linear guide rail group 22 drives the wire pulling hook cantilever 23 to carry the first wire pulling hook 24 to move toward the wire harness, and the semicircular edge at the bottom end of the first wire pulling hook 24 squeezes the tying wire, so that the first wire pulling hook 24 can move to one side of the tying wire, and then return, the straight edge of the first wire pulling hook 24 will hook the tying wire between the tying wire shaft 14 and the pneumatic clamp 19, so that the tying wire shaft 14, the first wire pulling linear guide rail group 22 and the pneumatic clamp 19 pull the tying wire at three points, thereby driving the tying wire to pass through the gap at the axis position of the C-shaped toothed disc 12 and at one side of the wire harness. A U-shaped coil is formed on the side, and then the first wire-pulling cylinder inside the moving block 26 controls the two wire-tensioning posts 27 to pop out from the telescopic slot 2601 into the U-shaped coil surrounded by the tying wire, and then the first wire-pulling linear guide rail group 22 drives the first wire-pulling hook 24 to move toward the wire harness again, so that the coil is separated from the first wire-pulling hook 24 and becomes loose, so that the coil falls on the top of the moving block 26, and then the first wire-pulling hook 24 returns again. At this time, the height of the coil is lower than the height of the bottom end of the first wire-pulling hook 24, so that the first wire-pulling hook 24 returns to the initial position without contacting the coil;

[0049] Winding of the tying wire: Start the winding mechanism, the winding motor 6 drives the synchronous shaft 7 to rotate through the synchronous pulley set 8, and the synchronous shaft 7 drives the C-shaped toothed disc 12 to start rotating through the meshing synchronous gear 9 and the transmission gear 10, and then drives the tying wire mounting seat 13 and the tying wire shaft 14, that is, one end of the tying wire starts to rotate, so that the tying wire is wound around the wire harness for a specified number of turns, and the U-shaped coil gradually moves upward along the wire tensioning pole 27 under the influence of the tying wire winding action and is tightened on the two wire tensioning poles 27;

[0050] Tie the tying wire: The second wire pulling cylinder inside the moving block 26 controls the second wire pulling hook 28 to pop out, and the second wire pulling linear guide rail group 25 drives the moving block 26 to move toward the wire harness, so that the semicircular edge of the second wire pulling hook 28 squeezes the tying wire, thereby moving the second wire pulling hook 28 to one side of the tying wire between the tying wire shaft 14 and the wire harness. When the second wire pulling hook 28 returns, the straight edge of the second wire pulling hook 28 will contact the tying wire between the tying wire shaft 14 and the wire harness and pull it, and then the second wire pulling hook 28 will shrink into the telescopic groove 2601, so that the tying wire is flattened on the top of the moving block 26. At this time, there is a height difference between the binding wire on the second wire hook 28 and the coil on the moving block 26, so that the binding wire pulled by the second wire hook 28 passes through the coil tightened on the wire post 27. At this time, the moving block 26 moves a short distance toward the wire harness for the second time, so that the coil is relaxed on the two wire posts 27, and then the wire post 27 shrinks into the telescopic groove 2601, so that the coil and the wire post 27 are completely separated, and finally the pneumatic clamp 19 moves with the wire end of the binding wire, so that the U-shaped coil is tightened on the wire harness under the drive of the wire end, so that the binding wire pulled back by the second wire hook 28 is knotted with the coil;

[0051] Cutting of the bundling wire: the cutting cylinder 29 drives the cutting knife 31 to descend through the knife seat 30, cutting the bundling wire on the second wire hook 28, the second wire hook 28 pops out to release the bundling wire, and each station returns to the initial position, thus completing the automatic bundling of the wire harness.
