Description

Technical Field

[0001] This invention belongs to the field of wire harness winding speed control technology, specifically referring to a speed control structure for a winding machine for automotive wire harness tape. Background Technology

[0002] As a core component of automotive circuitry, automotive wiring harnesses form the main network of the vehicle's electrical system. A wiring harness is constructed by crimping copper contact terminals to electrical wires and cables, then protecting them with an outer layer of plastic insulation or a metal shell, and finally bundling them together to form an assembly for connecting circuits. During the manufacturing process of wiring harnesses, various types of tape are applied to the wires using a winding machine.

[0003] The existing speed control structure for automotive wiring harness tape wrapping machines has the following problems:

[0004] The existing speed control structure of automotive wiring harness tape wrapping machines does not have the ability to monitor the diameter of the wiring harness during the tape wrapping process. This results in a mismatch between the feed speed of the wiring harness and the wrapping speed of the tape. When the diameter of the wiring harness is large, the feed speed is slow and it is impossible to maintain a constant tape overlap rate. When the diameter of the wiring harness is small, the feed speed is fast and it is easy to cause the tape to be overstretched or exposed.

[0005] Therefore, it cannot meet the current requirements for the speed control structure of automotive wiring harness tape winding machines. Summary of the Invention

[0006] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides a speed control structure for automotive wire harness tape winding machines that can monitor the diameter of the wire harness during the tape winding process and ensure that the wire harness feed speed matches the tape winding speed.

[0007] The technical solution adopted in this solution is as follows: This solution proposes a speed-regulating structure for a winding machine for automotive wiring harness tape, including a winding table, a circular groove, a straight-guide winding mechanism, and a resistance-sensing diameter measuring mechanism. The circular groove is located on one side wall of the winding table and is open on three sides. The straight-guide winding mechanism includes a drive assembly, a wrapping assembly, a guide assembly, and a winding assembly. The drive assembly is located on the inner wall of the winding table at the end away from the circular groove. The wrapping assembly is located on the side wall of the winding table. The guide assembly is located at the end of the winding table near the circular groove. The winding assembly is located at the end of the winding table near the drive assembly. The resistance-sensing diameter measuring mechanism includes a positioning assembly and a resistance assembly. The positioning assembly is located inside the wrapping assembly, and the resistance assembly is located inside the positioning assembly.

[0008] As a further preferred embodiment of the present invention, the drive assembly includes a winding motor, a drive gear shaft, a driven gear shaft, and a synchronous belt. The winding motor is located on the inner wall of the winding table at the end away from the circular groove. The drive gear shaft is located at the power end of the winding motor. Multiple sets of driven gear shafts are arranged in an arc shape on the side wall of the winding table on one side of the circular groove and are rotatably connected to the winding table. The synchronous belt is wound between the drive gear shaft and the driven gear shaft and meshes with both the drive gear shaft and the driven gear shaft respectively. The winding assembly includes a winding reel, a tape seat, a fixing bolt, a fixing plate, and an auxiliary wheel. The winding reel is rotatably located on the side wall of the winding table outside the circular groove. The side of the synchronous belt away from the driven gear shaft is in contact with the winding reel. The tape seat is located on the side wall of the winding reel. The fixing bolt is located on the side of the tape seat away from the winding reel and is threadedly connected to the tape seat. The fixing plate is located on the side wall of the winding reel. At the end of the bolt away from the tape seat, multiple sets of auxiliary wheels are rotatably mounted on the side wall of the winding table away from the driven gear shaft of the circular groove, with the auxiliary wheels in contact with the side wall of the winding reel; the guiding assembly includes a guide frame, a guide sleeve, a straightening frame, and a straightening wheel. The guide frame is located on the side of the winding table away from the driven gear shaft, the guide sleeve is located at the end of the guide frame away from the winding table and is coaxial with the circular groove, the straightening frame is located on the side of the winding table away from the guide frame, and the straightening wheel is rotatably mounted at the end of the straightening frame away from the winding table, with the straightening wheel located on the side of the circular groove axis; the winding assembly includes a winding frame, a winding roller, and a winding motor. The winding frame is located at the end of the winding table away from the guide frame, the winding roller is rotatably mounted at the end of the winding frame away from the winding table, and the winding motor is located on the upper wall of the winding frame, with the power end of the winding motor passing through the winding frame and connected to the winding roller.

[0009] In use, the wire harness to be wound passes through the guide sleeve and the circular groove, then wraps half a turn around the guide roller and onto the outside of the winding roller. The fixing bolt is unscrewed from inside the tape holder, the fixing plate detaches from the side wall of the winding reel, and the tape roll is inserted into the outside of the tape holder. The fixing bolt is screwed into the tape holder, causing the fixing plate to compress and fix the tape roll. The tape is pulled and wound around the outside of the wire harness, thus initially connecting the tape to the wire harness. The winding motor's power end drives the drive gear shaft to rotate, and the drive gear shaft drives the driven gear shaft via a synchronous belt. As the synchronous belt rotates, its sidewalls come into contact with the surface of the winding reel. When the synchronous belt is driven between the drive gear shaft and the driven gear shaft, it uses the frictional resistance between itself and the surface of the winding reel to drive the winding reel to rotate circumferentially along the sidewall of the winding table. The winding motor drives the winding roller to rotate through the power end. The winding roller rotates to wind the wire bundle of the tape. The winding reel drives the tape to fall off from the outside of the tape roll and wrap around the outside of the fed wire bundle through the tape seat. The end of the wire bundle away from the winding roller gradually falls off from the outside of the reel to perform the tape wrapping operation.

[0010] Preferably, the positioning assembly includes a positioning frame and a positioning sleeve. The positioning frame is disposed on the inner wall of the winding reel, and the positioning sleeve is disposed through the inner wall of the positioning frame. The resistance assembly includes an annular groove, a rotation measuring coil, a rotation measuring sleeve, a resistance rubber layer, a rotation measuring magnet, and a current sensor. The annular groove is disposed on the inner wall of the positioning sleeve and is open. The rotation measuring coil is disposed on the inner wall of the annular groove. The rotation measuring sleeve is rotatably disposed inside the positioning sleeve and extends out of the positioning sleeve at both ends. Multiple sets of the resistance rubber layer are disposed on the inner wall of the rotation measuring sleeve. Multiple sets of the rotation measuring magnet are disposed on the side wall of the rotation measuring sleeve inside the annular groove and are located inside the rotation measuring coil. The current sensor is disposed on the side wall of the winding table and is electrically connected to the rotation measuring coil.

[0011] In operation, the winding reel drives the positioning sleeve to rotate via the positioning frame. The positioning sleeve then drives the measuring sleeve to rotate outside the wire harness. After passing through the measuring sleeve, the wire harness enters the winding area. When the wire harness diameter is large, it contacts the resistance rubber layer. During the wire harness feeding process, the friction between the measuring sleeve and the resistance rubber layer increases the resistance to the rotation of the measuring sleeve, making the measuring sleeve rotate slower than the positioning sleeve. The measuring sleeve drives the measuring magnet to remain stationary. The winding reel drives the measuring coil to rotate via the positioning frame. At this time, the measuring coil and the measuring magnet are in relative motion. The measuring magnet cuts magnetic lines of force inside the measuring coil, generating a current inside the measuring coil. The current sensor monitors the magnitude of the current generated inside the measuring coil. When the frictional resistance between the wire harness and the resistance rubber layer is large, the current sensor detects a large current value inside the measuring coil, indicating a large wire harness diameter. The feed speed of the wire harness is increased accordingly to maintain a constant overlap rate. The winding motor increases the winding speed of the winding roller through the power end.

[0012] Specifically, a controller is provided on the side wall of the winding table.

[0013] The controller is electrically connected to the winding motor, the winding motor and the current sensor respectively.

[0014] The beneficial effects achieved by this solution using the above structure are as follows:

[0015] Compared with existing technologies, this solution combines a straight-guided winding mechanism with a resistance-type diameter measuring mechanism. Through the setting of drive components, winding components, guide components, winding components, positioning components, and resistance components, the diameter of the wire harness can be monitored in real time during the wire harness feeding process. The monitored wire harness diameter feedback signal is used to adjust the winding speed of the wire harness after wrapping the tape, so that the tape winding speed matches the wire harness feeding speed, maintaining a constant pitch and coverage, keeping the overlap rate constant, and preventing the tape from being overstretched or exposed. The measuring magnet cuts magnetic lines of force inside the measuring coil. During the wire harness feeding process, the friction between the magnet and the resistance rubber layer increases the resistance to the rotation of the measuring sleeve. Current is generated inside the measuring coil. The current sensor monitors the magnitude of the current generated inside the measuring coil, thereby adjusting the winding speed of the wire harness to ensure the quality of the wire harness after winding.

The fixing bolt 12 is located on the side of the tape holder 11 away from the winding reel 10 and is threadedly connected to the tape holder 11. The fixing plate 13 is located at the end of the fixing bolt 12 away from the tape holder 11. Multiple sets of... The auxiliary wheel 14 is rotatably mounted on the side wall of the winding platform 1 on the side of the circular groove 2 away from the driven gear shaft 7, and the auxiliary wheel 14 is in contact with the side wall of the winding disc 10; the guide assembly 15 includes a guide frame 16, a guide sleeve 17, a straightening frame 18, and a straightening wheel 19.

The winding frame 21 is disposed at one end of the winding table 1 away from the guide frame 16.

The winding motor 23 is disposed on the upper wall of the winding frame 21, and the power end of the winding motor 23 passes through the winding frame 21 and is connected to the winding roller 22.

[0032] The positioning component 25 includes a positioning frame 26 and a positioning sleeve 27. The positioning frame 26 is disposed on the inner wall of the winding reel 10, and the positioning sleeve 27 is disposed through the inner wall of the positioning frame 26. The resistance component 28 includes an annular groove 29, a rotation measuring coil 30, a rotation measuring sleeve 31, a resistance rubber layer 32, a rotation measuring magnet 33, and a current sensor 34. The annular groove 29 is disposed on the inner wall of the positioning sleeve 27 and is open. The rotation measuring coil 30 is disposed on the inner wall of the annular groove 29. The rotation measuring sleeve 31 is rotatably disposed inside the positioning sleeve 27 and extends out of the positioning sleeve 27 at both ends. Multiple sets of the resistance rubber layers 32 are disposed on the inner wall of the rotation measuring sleeve 31. Multiple sets of the rotation measuring magnets 33 are disposed on the side wall of the rotation measuring sleeve 31 inside the annular groove 29 and are located inside the rotation measuring coil 30. The current sensor 34 is disposed on the side wall of the winding table 1 and is electrically connected to the rotation measuring coil 30.

[0033] The winding table 1 is equipped with a controller 35 on its side wall.

[0034] The controller 35 is electrically connected to the winding motor 5, the winding motor 23, and the current sensor 34, respectively.

[0035] In actual use, the operator unscrews the fixing bolt 12 from the inside of the tape holder 11, the fixing plate 13 is removed from the side wall of the tape reel 10, the tape roll is inserted into the outside of the tape holder 11, the fixing bolt 12 is screwed into the inside of the tape holder 11, and the fixing plate 13 is driven to squeeze and fix the tape roll.

[0036] The operator passes one end of the wire harness through the guide sleeve 17 and the positioning sleeve 27 in sequence. After the wire harness exits the positioning sleeve 27, it enters the tape winding area. The operator pulls the tape to wind around the outside of the wire harness, so that the tape and one end of the wire harness are connected. The controller 35 controls the winding motor 5 to start. The power end of the winding motor 5 drives the drive gear shaft 6 to rotate. The drive gear shaft 6 drives the driven gear shaft 7 to rotate through the synchronous belt 8. The side wall of the synchronous belt 8 is in contact with the surface of the winding reel 10. When the synchronous belt 8 is transmitted between the drive gear shaft 6 and the driven gear shaft 7, it uses the frictional resistance between itself and the surface of the winding reel 10 to drive it to rotate circumferentially along the side wall of the winding table 1. The winding reel 10 drives the tape roll to rotate through the tape seat 11. The tape roll is fixed on the tape seat 11. The tape on its outside is wound around the outside of the wire harness located in the winding area under the rotation of the tape seat 11.

[0037] After the operator pulls the wire harness with the tape out of the winding area, the wire harness winds half a turn around the guide wheel 19 and wraps around the outside of the winding roller 22 to ensure the straightness of the wire harness during feeding. The controller 35 controls the winding motor 23 to start. The winding motor 23 drives the winding roller 22 to rotate through the power end. The winding roller 22 rotates to wind up the wire harness with the tape. The tape reel 10 drives the tape to fall off from the outside of the tape roll and wrap around the outside of the fed wire harness through the tape seat 11. The end of the wire harness away from the winding roller 22 gradually falls off from the outside of the reel to perform the tape wrapping operation.

[0038] During the circumferential rotation of the winding reel 10, the positioning frame 26 drives the positioning sleeve 27 to rotate. The positioning sleeve 27 drives the measuring sleeve 31 to rotate on the outside of the wire harness. After the wire harness passes through the measuring sleeve 31, it enters the rubber wrapping area. The diameter of the resistance rubber layer 32 set inside the measuring sleeve 31 is a fixed value. When the diameter of the fed wire harness is large, it will stick to the inner wall of the resistance rubber layer 32, increasing the rotation resistance of the measuring sleeve 31, so that the measuring magnet 33 and the measuring coil 30 rotate relative to each other. When the diameter of the fed wire harness is small, it will not stick to the inner wall of the resistance rubber layer 32. The positioning sleeve 27 drives the measuring sleeve 31 and the measuring magnet 33 to rotate synchronously.

[0039] When the diameter of the fed wire harness is large, frictional resistance is generated between the wire harness and the resistance rubber layer 32. The resistance rubber layer 32 reduces the rotational speed of the measuring sleeve 31 and the measuring magnet 33 following the positioning sleeve 27, causing relative rotation between the measuring magnet 33 and the measuring coil 30. The measuring magnet 33 cuts magnetic lines of force inside the measuring coil 30, generating current inside the measuring coil 30. The current sensor 34 monitors the magnitude of the current generated inside the measuring coil 30. When the current sensor 34 detects a large current value inside the measuring coil 30, it indicates that the wire harness diameter is large. The controller 35 controls the winding motor 23 to drive the winding roller 22 to increase the winding speed of the wire harness accordingly, thereby increasing the feed speed of the wire harness to maintain a constant tape overlap rate.

[0040] When the diameter of the feed wire harness is small, no frictional resistance is generated between the wire harness and the resistance rubber layer 32. The measuring sleeve 31 and the measuring magnet 33 maintain synchronous rotation with the positioning sleeve 27. The measuring magnet 33 will not cut the magnetic field lines inside the measuring coil 30. No current is generated inside the measuring coil 30. The current sensor 34 cannot detect the current value inside the measuring coil 30, thus maintaining the winding speed of the wire harness. The above operation can be repeated for the next use.

[0041] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0042] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
