Description

Technical Field

[0001] The invention relates to the technical field of wire harness wrapping, in particular to an automatic tape wrapping device for automobile wire harness casings. Background Art

[0002] The automotive wiring harness is the network backbone of the vehicle's electrical circuits. Without it, there would be no automotive circuits. A wiring harness is a component that connects electrical circuits by crimping copper contact terminals with wires and cables, then wrapping them with plastic-molded insulation or a metal casing.

[0003] The patent with announcement number CN117690663B discloses a wire harness tape winding device, including a guide mechanism for guiding a dispersed wire harness, a winding mechanism for wrapping the wire harness with tape, and a correction mechanism for limiting the position of the wire harness when winding. The bottom of the winding mechanism is fixed on a workbench, the guide mechanism is arranged at the feed end of the winding mechanism, and the discharge end of the winding mechanism is provided with a pulling mechanism. Several correction mechanisms are evenly installed on the outer circular surface of one side of the guide mechanism corresponding to the winding mechanism, and a release mechanism is installed inside the guide mechanism to assist the correction mechanism in preventing the wire harness from twisting.

[0004] However, the above invention patent still has some shortcomings in actual use: 1. The traditional tape is in direct contact with the wiring harness, and the tape is pulled out by the tension between the two, and then a correction mechanism is set to prevent the wiring harness from being twisted into a spiral shape. However, in reality, the speed of mechanically winding the tape is extremely fast, and correction by springs is not reasonable; 2. During the replacement of the wiring harness, the cutting of the tape and the re-bonding of the next wiring harness are usually done manually or by a robotic arm. The former is a waste of human resources, and the latter is more expensive. Therefore, an automatic tape wrapping device for automotive wiring harness sleeves is proposed to solve the above-mentioned problems. Summary of the Invention

It is set that the pulled-out tape roll 5 is not tightly attached to the first limiting bracket 12, the second limiting bracket 14 and the third limiting bracket 11, but loosely. The third limiting bracket 11 and the first channel 39 are only for limiting the direction of pulling out the tape roll 5. The initial tape connection is only required each time a new tape roll 5 is replaced. The wiring harness is placed on the wiring harness limiting rod 2 and the traction device 3. The traction device 3 pulls the wiring harness to move, and the rotating motor 7 rotates to drive the rotating ring 9 to rotate through the driving gear 8, and the rotating ring 9 drives the glue storage tray 6 to rotate.

Figure 5 When the position shown moves close to one side of the arc-shaped limit rod 10, the two clamping plates 13 are open. After clamping the tape, it is pulled backward. When it moves to the tail end, the two clamping plates 13 are opened again. The two alternating glue-pulling mechanisms 101 make the two clamping plates 13 simulate the state of two hands pulling the tape alternately, avoiding the situation where the tape is pulled through the wiring harness and the wiring harness is twisted.

[0048] Among them, the fixed-point loosening mechanism 202 includes two baffles 33, two baffles 16, two first springs 32 and two bidirectional triangular push rods 34.

[0050] Among them, the automatic gluing mechanism 404 includes a degumming plate 18, a pasting plate 37, a second belt 49, a third rack 54, a transmission gear 38 and two transmission shafts 2 50.

The degumming plate 18 is set above the positioning plate 51, and the degumming plate 18 is fixedly connected to the inner wall of the arc-shaped limit rod 10.

[0051] In this embodiment, the pressurized airbag 36 can be inflated during winding, so that the pressurized airbag 36 is more closely attached to the outer wall of the harness, and the tape is tightly attached to the harness. When the tape is wound, the second motor 42 drives the positioning gear 43 as shown in FIG. Figure 7 The shown direction rotates clockwise, so that when the positioning plate 51 moves downward, the tape will stick to the positioning plate 51 to prevent the end of the tape from falling off after the tape is cut. At the same time, the cutting gear 46 is driven to rotate synchronously through the action of the first belt 44 and the two first transmission shafts 45. The diameter of the cutting gear 46 is set to be larger than the positioning gear 43, so that the cutting gear 46 drives the second rack 52 to move and drives the cutting knife seat 53 to move to the bottom of the triangle 48. A cutting knife is provided on the cutting knife seat 53. Since the first slide rail 47 is opened in an inclined state, the end of the tape is left empty, which is the distance of the bottom side length of the triangle 48.

[0052] When the wiring harness is replaced with a new one, the second motor 42 reverses, and at the same time drives the cutting gear 46 and the second rack 52 to reset through the first belt 44, and the cutting knife seat 53 retracts into the arc limit rod 10, and the positioning gear 43 drives the first rack plate 40 to move up until the positioning plate 51 conflicts with the inner wall of the arc limit rod 10. At this time, the third rack 54 will drive the transmission gear 38 to rotate, and the transmission gear 38 drives the pasting plate 37 to rotate through the second belt 49, so that a section of the tape in the previous step is left empty and is pasted to one end of the new wiring harness by the transmission shaft 2 50, and the positioning plate 51 moves up the degumming plate 18 to push down the tape pasted on the bottom of the positioning plate 51, so that the tape head can automatically position and cut the tape head after the wiring harness is pasted, and the next new wiring harness can be automatically pasted on.

[0053] The specific working principle and use method of the present invention are explained in detail below: When using, Figure 10 As shown, first, the smooth side of the tape is tightly attached to the first limiting bracket 12, and the tape is pulled out from the notch on the glue storage tray 6, so that the tape contacts the first limiting bracket 12 and passes through between the second limiting bracket 14 and the arc-shaped limiting rod 10, and then passes through the third limiting bracket 11 and the first channel 39, and finally sticks to the wiring harness through the notch at the semi-arc of the arc-shaped limiting rod 10, and then stretches out a piece of tape roll 5. It is set that the pulled-out tape roll 5 is not tightly attached to the first limiting bracket 12, the second limiting bracket 14 and the third limiting bracket 11, but loosely. The third limiting bracket 11 and the first channel 39 are only for limiting the direction of pulling out the tape roll 5. The initial tape connection is only required each time a new tape roll 5 is replaced. The wiring harness is placed on the wiring harness limiting rod 2 and the traction device 3. The traction device 3 pulls the wiring harness to move, and the rotating motor 7 rotates to drive the rotating ring 9 to rotate through the driving gear 8, and the rotating ring 9 drives the glue storage tray 6 to rotate.

[0054] The two telescopic rods 24 are alternately extended and retracted, and the two telescopic rods 24 are alternately extended and retracted by the PLC program. The two telescopic rods 24 are both electric telescopic rods, so that the driving rod 23 drives the first shaft rod 22, the mounting seat 17 and the connecting seat 25 to move around the trapezoidal slide 26. The function of the slide plate 20 and the slide rod 21 is to limit the driving rod 23 to always maintain a vertical movement state. By default, the two clamping plates 13 are always closed due to the action of the clamping spring 55. Therefore, through the baffles 16 set at both ends of the mounting plate 19, when the clamping plate 13 moves to the end, the baffle 33 on the corresponding side will conflict with the baffle 16, thereby driving the two-way triangular push rod 34 in the corresponding direction to be inserted between the lower rotating seat 29 and the upper rotating seat 30, thereby driving the two clamping plates 13 to open and disengage from the tape. Therefore, when the first gear 35 moves along the trapezoidal slide 26 as shown Figure 5When the position shown moves close to one side of the arc-shaped limit rod 10, the two clamping plates 13 are open. After clamping the tape, it is pulled backward. When it moves to the tail end, the two clamping plates 13 are opened again. The two alternating glue-pulling mechanisms 101 make the two clamping plates 13 simulate the state of two hands pulling the tape alternately, avoiding the situation where the tape is pulled through the wiring harness and the wiring harness is twisted.

[0055] During the winding process, the pressurized airbag 36 can be inflated to make the pressurized airbag 36 fit more closely to the outer wall of the wiring harness, and the adhesive tape can be firmly attached to the wiring harness. When the adhesive tape is wound, the second motor 42 drives the positioning gear 43 to rotate. Figure 7 The shown direction rotates clockwise, so that when the positioning plate 51 moves downward, the tape will stick to the positioning plate 51 to prevent the end of the tape from falling off after the tape is cut. At the same time, the cutting gear 46 is driven to rotate synchronously through the action of the first belt 44 and the two first transmission shafts 45. The diameter of the cutting gear 46 is set to be larger than the positioning gear 43, so that the cutting gear 46 drives the second rack 52 to move and drives the cutting knife seat 53 to move to the bottom of the triangle plate 48. A cutting knife is provided on the cutting knife seat 53. Since the first slide rail 47 is opened in an inclined state, the end of the tape is left empty, which is the distance of the bottom side length of the triangle plate 48.

[0056] When the wiring harness is replaced with a new one, the second motor 42 reverses, and at the same time drives the cutting gear 46 and the second rack 52 to reset through the first belt 44, and the cutting knife seat 53 retracts into the arc limit rod 10, and the positioning gear 43 drives the first rack plate 40 to move up until the positioning plate 51 conflicts with the inner wall of the arc limit rod 10. At this time, the third rack 54 will drive the transmission gear 38 to rotate, and the transmission gear 38 drives the pasting plate 37 to rotate through the second belt 49, so that a section of the tape in the previous step is left empty and is pasted to one end of the new wiring harness by the transmission shaft 2 50, and the positioning plate 51 moves up the degumming plate 18 to push down the tape pasted on the bottom of the positioning plate 51, so that the tape head can automatically position and cut the tape head after the wiring harness is pasted, and the next new wiring harness can be automatically pasted on.
