Description

Technical Field

[0001] The present application relates to the field of wire harness processing technology, and in particular to an automotive wire harness tape winding device and a winding method. Background Art

[0002] Automotive wiring harnesses are a core component of a vehicle's electrical system. They are typically bundled together with multiple cables, each connected to terminals for electrical connectivity. To ensure mechanical strength, abrasion resistance, and electromagnetic shielding, the cables are typically wrapped with tape.

[0003] In practice, tape wrapping presents significant challenges, particularly for wire harnesses with flat terminals (i.e., flat terminals at both ends with a horizontally arranged cable in the middle). While tape provides a certain amount of radial tension to keep the cables together, when there are a large number of cables, the large gaps between them and the lack of effective restraint make it difficult for the cables to converge evenly toward the center of the harness during wrapping. This results in a flat or elliptical cross-section of the bundle after wrapping, rather than the ideal, approximately cylindrical shape.

[0004] This non-cylindrical wiring harness has the following defects in actual application: 1. Poor assembly adaptability: The internal wiring harness of the car usually needs to be fixed by round buckles, while flat or oval wiring harnesses cannot fit tightly with the buckles and are prone to loosening or even falling off, affecting the reliability of the electrical connection; 2. Uneven stress on the tape: The irregular shape of the wiring harness may cause the tape to be subjected to excessive local force, resulting in wrinkles or loosening, reducing the mechanical strength and durability of the wiring harness.

[0015] In a second aspect, the present application discloses a method for winding an automotive wiring harness tape, which utilizes the automotive wiring harness tape winding device described in the first aspect, and includes the following steps: S1. Fix the terminals at both ends of the wiring harness horizontally on the first clamping unit and the second clamping unit respectively to keep the wiring harness in a straight state; S2, performing fixed gathering of the cables at the ends of the wiring harness by closing the first gathering member and the second gathering member on the fixed gathering mechanism; S3, horizontally driving the movable gathering mechanism to translate toward the wire harness so that the centers of the first gathering member and the second gathering member are aligned with the wire harness, and vertically driving the movable gathering mechanism to move upward so that the opposite sides of the first gathering member and the second gathering member are aligned with the wire harness, and the first gathering member and the second gathering member on the movable gathering mechanism are brought together to gather the cables at the winding front end of the wire harness; S4, horizontally moving the tape winding mechanism so that the tape winding mechanism is sleeved on the wire harness and enters the tape winding preparation state; S5. Synchronously move the movable gathering mechanism and the tape winding mechanism in the length direction of the wire harness, the movable gathering mechanism gathers the cables at the winding front end of the wire harness, and the tape winding mechanism winds the gathered wire harness with tape.

[0016] Compared with the prior art, this application has the following beneficial effects: (1) Through the dual constraints of fixed and mobile gathering mechanisms, the cables are actively gathered before winding, especially in the easily dispersed areas at the ends of the harness. At the same time, the gathering position is dynamically adjusted during the winding process to avoid secondary displacement of the cables due to the tension of the tape winding. The cables are stably gathered throughout the winding process, making the cross-sectional shape of the harness close to the ideal cylindrical shape, improving the assembly compatibility with the circular buckle. The cable gap is evenly reduced during tape winding, and the stress distribution of the tape is more uniform, reducing local wrinkles or loosening, and enhancing the mechanical strength and durability of the harness.

[0017] (2) By horizontally sliding the second movable rod above the first movable rod, there is a sliding constraint between the second movable rod and the first movable rod in the vertical direction, which can eliminate the need for the second movable rod to be separately connected to the mounting plate in the horizontal direction, so that the first movable rod and the second movable rod are arranged in the vertical direction to avoid horizontal space occupation. In this way, it can be avoided that when the tape winding mechanism avoids due to horizontal space occupation, the situation of no tape winding at the end of the wire harness is further aggravated.

[0018] (3) By setting up an anti-extrusion component in the gathering mechanism, intelligent protection of the cable gathering process is achieved. When the gathering parts begin to close, the pre-extended telescopic rod forms a physical barrier, effectively preventing the cables from overflowing to the docking end face; as the closing process progresses, the telescopic rod retracts smoothly under the action of contact pressure, and the buffering effect of the elastic part realizes progressive closing, which ensures that all cables can be accurately constrained in the cylindrical space formed by the annular gathering surface, and avoids the extrusion damage to the cables caused by traditional rigid closing.

[0019] (4) By adding a second slide, a third actuator, and a lifting module, the multi-degree-of-freedom precision control of the mobile gathering mechanism is achieved. This design enables the gathering mechanism to separate the gathering parts when it reaches the end of the wire harness, and then completely separate from the wire harness through vertical lifting and lateral translation, thereby freeing up operating space for the tape winding mechanism, completely solving the technical problem of the traditional solution that the end of the wire harness cannot be wound.

[0020] (5) By adding a tape guide assembly, precise positioning and pre-bonding of the tape during winding are achieved. The synergistic effect of the guide column and the guide plate allows the tape to enter the storage chamber at a preset angle and be laid horizontally on the guide portion. When the wire harness is introduced, the tape is automatically squeezed and wrapped around the surface of the wire harness in the storage chamber. This structure effectively constrains the radial displacement of the wire harness, preventing deformation of the wire harness due to radial displacement during winding, and eliminating the problem of tape wrinkling caused by the shaking of the wire harness in traditional winding.

[0021] (6) By setting up a tape cutting assembly consisting of a support block, a lower pressure block, a cutter, and a double lifting element, the tape is accurately cut and the fracture is positioned after winding. This design controls the clamping and cutting actions in steps. First, the lower pressure block and the support block stably clamp the wire harness, and then the independently controlled cutter completes the vertical cutting, ensuring that the cut is smooth and burr-free. At the same time, the adhesive film on the top surface of the support block and the centrifugal film on the bottom surface of the lower pressure block are used to ensure the accurate positioning of the tape fracture and avoid the tape sticking during reset.

[0024] The following will be combined with the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] like Figure 1 As shown, combined Figure 2 and 3 The embodiment of the present application discloses an automotive wiring harness tape winding device, including a base plate 1, a clamping mechanism 6, a fixed gathering mechanism 2, a movable gathering mechanism 3, a tape winding mechanism 4 and a driving mechanism 5.

[0026] The bottom plate 1 is a part of the entire automotive wiring harness tape winding device, which is installed inside the device to provide a basis for the installation of other components and mechanisms.

[0027] The clamping mechanism 6 includes a first clamping unit 61 and a second clamping unit 62 disposed opposite each other on the base plate 1 and is used to horizontally secure the terminals D at both ends of the wiring harness P. The first clamping unit 61 and the second clamping unit 62 can be implemented using pneumatic grippers or mechanical clamps to ensure that the wiring harness P remains straight during the winding process.

[0028] The fixed gathering mechanism 2 is fixedly arranged on the base plate 1 on the inner side of the first clamping unit 61, and includes two symmetrically arranged first gathering pieces 21 and second gathering pieces 22. The first gathering pieces 21 and the second gathering pieces 22 can move horizontally relative to each other to perform fixed gathering of the cables L at the end of the wiring harness P.

[0029] In this embodiment, the first gathering piece 21 and the second gathering piece 22 both have a semicircular gathering surface 210. In this embodiment, the gathering surface 210 is an arc-shaped concave structure, and the axis of the gathering surface 210 is parallel to the wiring harness P. The two symmetrically arranged gathering pieces are moved horizontally to apply radial constraints to the cables L at the end of the wiring harness P, so that multiple cables L are gathered together to form a wiring harness P that is approximately cylindrical. The contour of the gathering surface 210 is adapted to the gathering outer diameter of the wiring harness P, so that the cables L in the wiring harness P can be closely brought together after gathering, ensuring that the cables L are evenly stressed during the gathering process.

[0030] The mobile gathering mechanism 3 is located on a side of the fixed gathering mechanism 2 away from the first clamping unit 61. Its structure is the same as that of the fixed gathering mechanism 2 and is used to movably gather the cables L at the winding front end of the wire harness P. In this embodiment, the mobile gathering mechanism 3 can gather and move at the winding front end of the wire harness P. Because the fixed gathering mechanism 2 gathers the cables L at the end of the wire harness P, it can apply a first gathering force point in the axial direction of the wire harness P, while the mobile gathering mechanism 3 applies a second gathering force point on the wire harness P. Because the mobile gathering mechanism 3 is accompanied by translation during the gathering process, the wire harness P between the two gathering points can maintain a straight and stable gathered state.

[0031] The tape winding mechanism 4 is located between the fixed gathering mechanism 2 and the movable gathering mechanism 3 and is used for winding the gathered wire harness P with tape.

[0032] The driving mechanism 5 is fixedly arranged on the base plate 1 and is used for synchronously driving the movable gathering mechanism 3 and the tape winding mechanism 4 to translate along the length direction of the wire harness P.

[0033] Specifically, after the terminals D at both ends of the wiring harness P are fixed by the clamping mechanism 6, the first gathering piece 21 and the second gathering piece 22 of the fixed gathering mechanism 2 are horizontally closed to gather the end cables L into a cylindrical shape. The initial position of the mobile gathering mechanism 3 is close to the fixed gathering mechanism 2, and its gathering pieces are closed to constrain the cables L at the starting position of winding. The tape winding mechanism 4 moves to the top of the wiring harness P. After the driving mechanism 5 is started, the mobile gathering mechanism 3 and the tape winding mechanism 4 are synchronously translated along the length direction of the wiring harness P. The mobile gathering mechanism 3 continues to pre-gather the cable L section to be wound, and the tape winding mechanism 4 rotates and wraps the tape during the translation process, so that the tape forms a uniform spiral layer on the surface of the gathered cable L. Through the synergistic effect of the fixed and mobile gathering mechanisms, the cable L maintains a tightly gathered state throughout the winding process, and eventually forms an approximately cylindrical cross-section.

[0034] Traditional tape winding equipment relies solely on the tension of the tape itself to gather the cables L, failing to effectively control the gaps between them. This solution utilizes the dual constraints of fixed and mobile gathering mechanisms 3 to actively gather the cables L before winding. This system applies a fixed constraint specifically to the areas prone to dispersion at the ends of the harness P. It also dynamically adjusts the gathering position during the winding process to prevent secondary displacement of the cables L due to the tension of the tape winding. Synchronous control of the drive mechanism 5 ensures coordinated gathering and winding, fundamentally resolving the issue of irregular cross-sectional shapes in the harness P.

[0035] Through the above technical solution, the present application achieves stable gathering of the cables L throughout the winding process, making the cross-sectional shape of the wiring harness P close to an ideal cylinder, improving its compatibility with the circular buckle. During tape winding, the gaps between the cables L are evenly reduced, and the stress distribution of the tape is more uniform, reducing local wrinkling or loosening, and enhancing the mechanical strength and durability of the wiring harness P.

[0036] In order to realize the fixed gathering mechanism 2 to perform the gathering operation on the cables L, this embodiment discloses the specific structure of the fixed gathering mechanism 2. Figure 3 As shown, it further includes a mounting plate 23 , a first straight element, a first moving rod 25 , a second moving rod 26 and a double-rack reciprocating mechanism 27 .

[0037] The mounting plate 23 is vertically fixed on the base plate 1 , close to the side of the first clamping unit 61 facing the second clamping unit 62 . The mounting plate 23 provides a mounting base for other components.

[0038] The first actuator 24 is fixed to the mounting plate 23 and can be a pneumatic cylinder or an oil cylinder. The first moving rod 25 is slidably arranged on the top surface of the mounting plate 23, with one end fixedly connected to the first gathering member 21 and the other end connected to the first actuator 24. The second moving rod 26 is slidably arranged on the top surface of the first moving rod 25, arranged parallel to the first moving rod 25, and one end fixedly connected to the second gathering member 22. By extending or shortening the telescopic end of the first actuator 24, the first moving rod 25 can be driven to move horizontally on the top surface of the mounting plate 23, thereby driving the first gathering member 21 to move horizontally. In order to enable the first gathering member 21 to move closer to or apart from the second gathering member 22, a double rack reciprocating mechanism 27 is provided between the first moving rod 25 and the second moving rod 26 in this embodiment.

[0039] The double-rack reciprocating mechanism 27 includes a first rack 271, a second rack 272, and a linkage gear 273. The first rack 271 is fixed parallel to the first moving rod 25, and the second rack 272 is fixed parallel to the second moving rod 26. The linkage gear 273 is rotatably mounted on the mounting plate 23 and meshes with the first rack 271 and the second rack 272. Through the meshing relationship between the gears and the double racks, this mechanism converts the linear motion of the first moving rod 25 into the opposite, synchronous motion of the second moving rod 26, achieving symmetrical displacement of the two converging members.

[0040] Specifically, when the first actuator 24 drives the first movable rod 25 to move horizontally, the first rack 271 fixed thereto rotates the linkage gear 273, which in turn drives the second rack 272 to move in the opposite direction. Because the second movable rod 26 is fixedly connected to the second rack 272, the second gathering member 22 and the first gathering member 21 are symmetrically displaced. The axial direction of the semicircular gathering surface 210 is parallel to the extension direction of the wire harness P, forming a complete cylindrical confinement space during the closing process, forcing the dispersed cables L to converge toward the central axis.

[0041] Through the above-mentioned technical solution, the present application achieves a dynamic balance of the clamping forces on both sides during the gathering process of the cables L, ensuring that the cross-section of the harness P forms a uniform cylindrical structure. The forced synchronization mechanism of the linkage gear 273 avoids manual adjustment errors. The adaptive design of the semicircular gathering surface 210 and the outer diameter of the harness P eliminates stress concentration after tape wrapping, providing an ideal morphology foundation for the harness P during the subsequent tape wrapping process.

[0042] It is also worth noting that since the end of the wire harness P cannot be effectively wound after being gathered, the gathering length of the end of the wire harness P should be as small as possible. At the same time, it is necessary to ensure that the width of the entire fixed gathering mechanism 2 along the axial direction of the wire harness P is as small as possible, so as to avoid its width dimension being too large, resulting in an excessively large gathering length of the end of the wire harness P. The present application arranges the second movable rod 26 horizontally slidingly above the first movable rod 25, and there is a sliding constraint between the second movable rod 26 and the first movable rod 25 in the vertical direction. This can eliminate the need for the second movable rod 26 to be separately connected to the mounting plate 23 in the horizontal direction, so that the first movable rod 25 and the second movable rod 26 are arranged in the vertical direction to avoid horizontal space occupation. This can avoid the situation where there is no tape winding at the end of the wire harness when the tape winding mechanism avoids due to horizontal space occupation.

[0043] During the gathering process, when the first and second gathering members 21, 22 are not yet fully closed, the horizontally arranged cables L may shift vertically, and some cables L may be squeezed outward from the annular gathering surface 210. At this point, the butt-jointed end surfaces 211 of the gathering members may come into contact with these overflowing cables L, compressing them. This not only prevents the cables L from forming the ideal cylindrical gathering state but may also cause mechanical damage to the insulation layer of the cables L. This extrusion phenomenon is particularly pronounced when handling multiple cables L, directly impacting the gathering quality and safety of the wiring harness P.

[0044] In order to solve the above technical problems, the present application further provides an anti-extrusion component 28 on the fixed gathering mechanism 2. The fixed gathering mechanism 2 also includes an anti-extrusion component 28. Figure 5 and 6As shown, the anti-extrusion component 28 includes a telescopic rod 281 and an elastic member 282. The upper and lower sides of the first gathering member 21 and the second gathering member 22 are provided with mutually cooperating docking end faces 211. The docking end face 211 of the first gathering member 21 is horizontally provided with a mounting cavity 212. The mounting cavity 212 is located at the connection between the gathering surface 210 and the docking end face 211. The telescopic rod 281 is arranged in the mounting cavity 212. A limiting ring 2811 is fixedly provided on the telescopic rod 281. A fixed limiting portion 2121 is provided in the mounting cavity 212. The elastic member 282 is sleeved on the telescopic rod 281 and is located between the limiting ring 2811 and the fixed limiting portion 2121. When the first gathering piece 21 and the second gathering piece 22 are separated, the telescopic rod 281 extends out of the outside of the docking end surface 211 of the first gathering piece 21 . When the first gathering piece 21 and the second gathering piece 22 are closed, the telescopic rod 281 is compressed back into the installation cavity 212 .

[0045] In this embodiment, the limiting ring 2811 is held against the side of the mounting cavity 212 facing the docking end face 211, and the fixed limiting portion 2121 is arranged on the side of the inner side of the mounting cavity 212 away from the docking end face 211. One end of the telescopic rod 281 passes through the mounting cavity 212 and movably extends outward from the docking end face 211, and the other end movably passes through the fixed limiting portion 2121. In the absence of external force, the elastic member 282 itself drives the limiting ring 2811 to press against the inner end face of the mounting cavity 212 facing the docking end face 211. When the first gathering member 21 and the second gathering member 22 are brought close to each other, the telescopic rod 281 in the first gathering member 21 is closed. The end 81 will first abut against the mating end surface 211 of the second gathering piece 22. During the closing process, when the cable L moves in the vertical direction, the telescopic rod 281 can block the cable L to prevent the cable L from overflowing between the mating end surfaces 211 of the first gathering piece 21 and the second gathering piece 22. Therefore, when the first gathering piece 21 and the second gathering piece 22 are completely closed, all the cables L are gathered into a cylindrical structure in the annular constraint space formed by the two half-type gathering surfaces 210. At the same time, when the telescopic rod 281 is pressurized by the mating end surface 211 of the second gathering piece 22, it compresses the elastic part 282, thereby retracting into the installation cavity 212.

[0046] This application implements intelligent protection for the gathering process of the cables L by providing an anti-extrusion component 28 in the gathering mechanism. When the gathering member begins to close, the pre-extended telescopic rod 281 forms a physical barrier, effectively preventing the cables L from overflowing toward the docking end surface 211. As the closing process progresses, the telescopic rod 281 steadily retracts under the action of contact pressure, and the buffering effect of the elastic member 282 achieves progressive closing, ensuring that all cables L can be precisely constrained within the cylindrical space formed by the annular gathering surface 210, while avoiding the extrusion damage to the cables L caused by traditional rigid closing.

[0047] This application further discloses the specific structure of the driving mechanism 5. Figure 6 As shown, it includes a sliding frame 51, a mounting platform 52, a first sliding table 53, a linear module 54 and a second actuator 55. The sliding frame 51 is fixedly arranged on the base plate 1 and is parallel to the length direction of the wire harness P. The mounting platform 52 is slidably arranged on the sliding frame 51. The linear module 54 is arranged on the sliding frame 51 to drive the mounting platform 52 to translate along the length direction of the sliding frame 51. The first sliding table 53 is slidably arranged on the mounting platform 52. The second actuator 55 is used to drive the first sliding table 53 to translate in a direction perpendicular to the wire harness P. The tape winding mechanism 4 is fixedly arranged on the first sliding table 53, and the movable gathering mechanism 3 is arranged on the mounting platform 52.

[0048] Among them, the sliding frame 51 is used to provide a sliding track for the installation platform 52 and ensure that the movement direction is consistent with the axis of the wire harness P. The installation platform 52 is a mobile base that carries the mobile gathering mechanism 3 and the tape winding mechanism 4. Specifically, it can adopt a structure with a slider to cooperate with the sliding frame 51, and realize precise positioning along the length direction of the wire harness P through the drive of the linear module 54. The first slide 53 is a transverse movable plate arranged on the installation platform 52. It is driven by the second actuator 55 to realize the displacement adjustment of the tape winding mechanism 4 perpendicular to the direction of the wire harness P. The linear module 54 is a power device that drives the installation platform 52 to move horizontally. Specifically, it can adopt a combination of a servo motor and a ball screw to control the synchronous movement speed of the tape winding mechanism 4 and the mobile gathering mechanism 3. The second actuator 55 refers to the power source that drives the first slide 53. Specifically, it can adopt a cylinder or an electric push rod to adjust the horizontal distance between the tape winding mechanism 4 and the wire harness P.

[0049] This solution integrates the mobile gathering mechanism 3 and the tape winding mechanism 4 on a single mounting platform 52, utilizing a linear module 54 to drive both synchronous movements, eliminating coordination issues associated with multiple power sources. Furthermore, the tape winding mechanism 4 and the mobile gathering mechanism 3 precisely and synchronously move along the length of the harness P, ensuring that the tape consistently covers the gathered area of ​​the cables L during the winding process. This eliminates issues such as tape misalignment or loosening of the cables L caused by asynchronous movement, thereby ensuring a uniform cross-sectional shape of the wrapped harness P.

[0050] In this embodiment, the first gathering piece 21 and the second gathering piece 22 in the fixed gathering mechanism 2 are separated from each other in the initial state. When the wire harness P is horizontally fixed on the clamping mechanism 6, the wire harness P is just between the first gathering piece 21 and the second gathering piece 22.

[0051] In some embodiments, the mobile gathering mechanism 3 is fixed on the mounting platform 52. In the initial state, the first gathering member 21 and the second gathering member 22 on the mobile gathering mechanism 3 are horizontally aligned with the first gathering member 21 and the second gathering member 22 in the fixed gathering mechanism 2, respectively. In this way, when the wire harness P is horizontally fixed on the clamping mechanism 6, the wire harness P is exactly located between the first gathering member 21 and the second gathering member 22 on the fixed gathering mechanism 2 and the mobile gathering mechanism 3. At this time, the working principles of the fixed gathering mechanism 2 and the mobile gathering mechanism 3 are the same. After the entire wire harness P is wrapped with tape, the first gathering member 21 and the second gathering member 22 on the fixed gathering mechanism 2 and the mobile gathering mechanism 3 are opened, the clamping mechanism 6 is released, and the wire harness P can be removed.

[0052] Since the mobile gathering mechanism 3 is blocked by the second clamping unit 62 after moving to the end of the wire harness P, and the mobile gathering mechanism 3 blocks the tape winding mechanism 4 from moving forward at this position, the end of the wire harness P also has the problem of being unable to be tape wound.

[0053] In order to solve the above problems, the present application further designs the structure of the driving mechanism 5. Figure 7 As shown, the mounting platform 52 is also provided with a second slide 56, a third actuator 57 and a lifting module. The second slide 56 is slidably set on the mounting platform 52. The third actuator 57 is used to drive the second slide 56 to translate in a direction perpendicular to the wiring harness P. The lifting module is set on the second slide 56 and is used to drive the mobile gathering mechanism 3 to move up and down.

[0054] The second slide 56 refers to a load-bearing structure with sliding functionality provided on the mounting platform 52. Specifically, it can be implemented using a combination of linear guides and sliders, and is used to support the movable gathering mechanism 3 and achieve lateral translation. The third actuator 57 is a power device that drives the second slide 56, such as a servo motor or cylinder, connected to the second slide 56 via a transmission mechanism to provide driving force. The lifting module is a mechanical device that achieves vertical position adjustment, such as a screw-nut mechanism or electric push rod, and is used to precisely control the height of the movable gathering mechanism 3.

[0055] Specifically, during the tape winding process, the third actuator 57 drives the second slide 56 to move in a direction perpendicular to the wire harness P, causing the mobile gathering mechanism 3 to move laterally closer to or farther away from the wire harness P. The lifting module adjusts its position in the vertical direction so that the semicircular gathering surfaces 210 of the first gathering member 21 and the second gathering member 22 of the mobile gathering mechanism 3 can be aligned with the axis of the wire harness P. Thus, the position of the mobile gathering mechanism 3 in both the lateral and vertical directions can be independently controlled. After the mobile gathering mechanism 3 moves to the end of the wire harness P, it can first separate through the first gathering member 21 and the second gathering member 22, and then perform vertical and lateral movements in sequence to separate the mobile gathering mechanism 3 from the wire harness P. At this point, the tape winding mechanism 4 can continue to advance, thereby completing the tape winding at the end of the wire harness P.

[0056] This application achieves multi-degree-of-freedom precision control of the mobile gathering mechanism 3 by adding a second slide 56, a third actuator 57, and a lifting module. This design enables the gathering mechanism to first separate the gathering components when reaching the end of the wire harness P, and then completely disengage from the wire harness P through vertical lifting and lateral translation, thereby freeing up operating space for the tape winding mechanism 4 and completely resolving the technical problem of the inability to wind the end of the wire harness P in traditional solutions. This avoidance mechanism not only ensures the complete winding of the entire section of the wire harness P, but also achieves a seamless connection between the gathering and winding processes through modular motion control, significantly improving the equipment's operating efficiency and the processing quality of the wire harness P.

[0057] This application further shows a structural mode of the tape winding mechanism 4. Figure 8-10 As shown, the tape winding mechanism 4 includes a fixing plate 41 , a gear ring 42 , a main gear 43 , a slave gear 44 , a tape reel 45 , a limiting roller 46 and a rotating motor 47 .

[0058] The fixing plate 41 is vertically fixed on the first slide 53. The surface of the fixing plate 41 has a through hole 411 for the wiring harness P to pass through. The fixing plate 41 has a first notch 412 horizontally opened at one end facing the clamping mechanism 6 and connected to the through hole 411. The first notch 412 is used to guide the wiring harness P into the through hole 411. In this embodiment, the center of the first notch 412 and the center of the through hole 411 are on the same horizontal plane, and are on the same horizontal plane as the center line of the wiring harness P. When the tape winding mechanism 4 moves horizontally toward the direction of the wiring harness P, the gathered wiring harness P can enter the through hole 411 through the first notch 412.

[0059] A gear ring 42 is mounted on the sidewall of the fixed plate 41 and coaxial with the through-hole 411. A second notch 421 is defined in the gear ring 42. The outer surface of the gear ring 42 is toothed, while the inner surface is a smooth annular surface. In this embodiment, the gear ring 42 rotates to drive the tape reel 45 about the through-hole 411. Initially, when the second notch 421 and the first notch 412 overlap, the wire harness P is guided into the through-hole 411 and the gear ring 42. Multiple limiting rollers 46 are evenly distributed along the inner wall of the gear ring 42 and are rotatably connected to the fixed plate 41. These limiting rollers 46 are used to constrain the gear ring 42 from rotating about the center of the through-hole 411. The tape reel 45 is fixedly arranged on the outside of the gear ring 42 for installing the tape, the main gear 43 and the slave gear 44 are rotatably arranged on the fixed plate 41 and are respectively engaged with the gear ring 42. The main gear 43 and the slave gear 44 are connected by a transmission member 48, and the rotating motor 47 is fixedly arranged on the fixed plate 41 for driving the main gear 43 to rotate.

[0060] Specifically, after the wiring harness P passes through the first notch 412 and the second notch 421 and enters the through-hole 411, the wiring harness P, the gear ring 42, and the through-hole 411 are now coaxial. The rotary motor 47 drives the main gear 43 to rotate, which in turn drives the slave gear 44 to rotate synchronously via the transmission member 48, thereby driving the gear ring 42 to rotate about the axis of the through-hole 411. The tape loaded on the tape reel 45 is pulled during the rotation of the gear ring 42, ensuring that the tape is always tightly attached to the outer surface of the wiring harness P and is spirally wound.

[0061] Since the initial end of the wiring harness P is gathered, the front end of the wiring harness P is gathered, and the wiring harness P between the two gathering points is approximately cylindrical. At this time, the tape is wound and moved on the surface of the wiring harness P, thereby realizing spiral winding, which can ensure that the wiring harness P is evenly stressed under the action of radial tension, and finally the wrapped wiring harness P forms a regular cylindrical shape, significantly improving its assembly adaptability with the circular buckle, while reducing local wrinkles or looseness, and enhancing the mechanical strength and durability of the wrapped wiring harness P.

[0062] Since the inner diameter of the gear ring 42 and the inner diameter of the through hole 411 are both larger than the outer diameter of the gathered wire harness P, the wire harness P is subjected to radial tension during the tape winding process, and the displacement change of the wire harness P in the radial direction cannot be effectively constrained, which will cause the surface of the wire harness P to be uneven and wrinkled after the tape is wound.

[0063] To this end, the tape winding mechanism 4 of the present application is also provided with a tape guiding assembly 49, which includes a guide column 491 and a guide plate 492. The guide plate 492 is fixedly arranged on the gear ring 42, and the guide plate 492 is bent to form a accommodating chamber 4921 corresponding to the position of the through hole 411, which is used to accommodate the wiring harness P. In this embodiment, the accommodating chamber forms a U-shaped or V-shaped space on the guide plate 492 through a bending process, which is used to limit the position deviation of the wiring harness P during the winding process.

[0064] The end of the storage bin 4921 facing the second notch 421 has a horizontally extending guide portion 4922, which is used to guide the tape to adhere to its upper surface. The side wall of the storage bin 4921 away from the guide portion 4922 is provided with a guide hole 4923, which can be a rectangular hole with a diameter slightly larger than the width of the tape, for guiding the tape to enter the storage bin 4921 at a preset angle. The guide hole 4923 is higher than the top surface of the guide portion 4922 in the vertical direction. In this way, the tape enters the storage bin 4921 through the guide hole 4923 and then extends To the guide part 4922, when the wire harness P is introduced from the first notch 412 and the second notch 421, the wire harness P will be introduced from the horizontally set guide part 4922 into the accommodating chamber 4921. At this time, during the introduction process of the wire harness P, the wire harness P first contacts the tape on the guide part 4922, and then is introduced into the accommodating chamber 4921. At the moment the wire harness P is introduced into the accommodating chamber 4921, the wire harness P will squeeze the tape in the accommodating chamber 4921, so that the tape is wrapped around the wire harness P in the accommodating chamber 4921, thereby providing a pre-bonding basis for the tape on the wire harness P.

[0065] There are multiple guide columns 491, which are rotated at intervals on the side wall of the gear ring 42. The guide columns 491 are used to guide the tape through the guide hole 4923 and into the receiving chamber 4921. The tape guided by the tape reel 45 is guided by multiple guide columns 491, and then passes through the guide hole 4923 and enters the receiving chamber 4921, thereby guiding the tape to the correct path.

[0066] This application achieves precise positioning and pre-bonding of the tape during winding by adding a tape guide assembly 49. The synergistic effect of guide post 491 and guide plate 492 allows the tape to enter storage chamber 4921 at a preset angle and lay horizontally on guide portion 4922. When the wire harness P is introduced, the tape is automatically squeezed and wrapped around the surface of the wire harness P in storage chamber 4921. This structure effectively constrains the radial displacement of the wire harness P, preventing deformation of the wire harness P during winding due to radial displacement, and eliminating the problem of tape wrinkling caused by the shaking of the wire harness P in traditional winding.

[0067] The outer surface of the guide post 491 in the above embodiment is wrapped with a release film, which can avoid or reduce the strong adhesion between the adhesive surface of the tape and the guide post 491, thereby achieving smooth guidance of the tape.

[0068] The present application further proposes that the tape winding mechanism 4 also includes a tape cutting assembly 40, which includes a support block 401, a lower pressure block 402, a cutter 403, a first lifting element 404 and a second lifting element 405. The support plate is fixedly arranged below the first notch 412, the lower pressure block 402 is located above the first notch 412 and corresponds to the position of the support block 401, the cutter 403 is vertically arranged on the side of the lower pressure block 402 away from the gear ring 42, the first lifting element 404 is used to drive the lower pressure block 402 to move up and down, and the second lifting element 405 is arranged on the lower pressure block 402 to drive the cutter 403 to move up and down.

[0069] The support block 401 is a supporting structure fixed below the first notch 412 and forming a clamping space with the lower pressure block 402. Specifically, it can be made of a metal block or high-strength plastic, and is used to stabilize the position of the wire harness P during tape cutting. The lower pressure block 402 is a movable pressure plate located above the first notch 412 and perpendicular to the support block 401. Specifically, it can be driven by a cylinder or an electric push rod to clamp the wire harness P before cutting to prevent displacement. The cutter 403 is a blade-like component mounted vertically on the side of the lower pressure block 402. Specifically, it can use a tungsten steel blade or a ceramic blade. It is used to perform the cutting operation after the tape is wrapped. The first lifting element 404 is an actuator that drives the lower pressure block 402 to move vertically. Specifically, it can use a linear motor or a hydraulic cylinder to control the clamping distance between the lower pressure block 402 and the support block 401. The second lifting element 405 is a drive unit that independently controls the vertical movement of the cutter 403. Specifically, it can use a micro cylinder or a stepper motor to precisely control the blade stroke during the tape cutting stage.

[0070] Specifically, after the tape is wound, the gear ring 42 is rotated to align the first notch 412 and the second notch 421. The tape winding mechanism 4 then moves horizontally away from the wiring harness P, allowing the wiring harness P to escape from the first notch 412 and the second notch 421. After the wiring harness P escapes, the tape is pulled out of the first notch 412 and the second notch 421. The tape is now positioned horizontally between the support block 401 and the lower pressure block 402. The first lifting element 404 drives the lower pressure block 402 downward and cooperates with the support block 401 to clamp the wiring harness P. The tape is now positioned outside the clamping area between the lower pressure block 402 and the support block 401. The second lifting element 405 then drives the cutter 403 downward, using the blade edge to cut the end of the tape. During the cutting process, the clamping action effectively prevents displacement of the wiring harness P due to the impact of cutting, while the vertical motion trajectory of the blade ensures a smooth cut. After the cut is completed, the lower pressure block 402 and the cutter 403 are synchronously reset, and the tape break is limited to the top surface of the support block 401. In order to ensure that the tape end does not shift, an adhesive film can be provided on the top surface of the support block 401. When the tape is cut, the non-stick surface of the tape cut can adhere to the support block 401, so that the tape on the support block 401 can smoothly contact and adhere to the surface of the wire harness P when the wire harness P is introduced next time. Correspondingly, a centrifugal film can be provided on the bottom surface of the lower pressing block 402 to prevent the adhesive surface of the tape from adhering to the bottom surface of the lower pressing block 402. In this way, the lower pressing block 402 only provides a downward clamping force. After the tape is cut, the lower pressing block 402 will not lift up the tape during the reset process.

[0071] This application achieves precise cutting and location of the tape after winding by providing a tape cutting assembly 40 consisting of a support block 401, a lower pressure block 402, a cutter 403, and a dual lifting element. This design controls the clamping and cutting actions in steps. First, the lower pressure block 402 and the support block 401 stably clamp the wire harness P, and then the independently controlled cutter 403 completes the vertical cut, ensuring a smooth and burr-free cut. At the same time, the adhesive film on the top surface of the support block 401 and the centrifugal film on the bottom surface of the lower pressure block 402 ensure accurate location of the tape break and avoid tape adhesion during resetting.

[0072] The present application further proposes that the clamping mechanism 6 also includes an adjusting device 63 , the first clamping unit 61 is fixedly arranged on the base plate 1 , and the adjusting device 63 is used to adjust the distance between the second clamping unit 62 and the first clamping unit 61 .

[0073] The adjustment device 63 is a mechanical structure used to change the horizontal position of the second clamping unit 62. This can be achieved using a screw-nut mechanism or a rack-and-pinion mechanism, with displacement generated by rotating a handwheel or driving a motor. Spacing adjustment dynamically adjusts the distance between the two clamping units based on the length of the wiring harness P. This is achieved through a linear motion pair composed of a slide rail and a slider, ensuring that the clamping units remain parallel during adjustment.

[0074] Specifically, when handling wire harnesses P of varying specifications, the operator can rotate the screw by rotating the handwheel of the adjustment device 63, thereby moving the second clamping unit 62 along the slide rail on the base plate 1. Graduated scales on either side of the slide rail assist in precisely controlling the travel distance. Once the second clamping unit 62 reaches the target position, it is secured with a locking bolt. This adjustment method ensures stable clamping of the terminals D at both ends of the wire harness P, preventing bending or loosening of the wire harness P due to mismatched clamping spacing. In some other embodiments, the adjustment device 63 may be equipped with an electric push rod as a drive source.

[0075] The present application further provides a method for winding an automotive wiring harness P tape, comprising the following steps: S1. Fix the terminals D at both ends of the wire harness P horizontally on the first clamping unit 61 and the second clamping unit 62 respectively to keep the wire harness P in a straight state.

[0076] S2. The cables L at the ends of the wiring harness P are fixedly gathered by closing the first gathering piece 21 and the second gathering piece 22 on the fixed gathering mechanism 2.

[0077] S3. Drive the mobile gathering mechanism 3 horizontally to translate toward the direction of the wire harness P so that the centers of the first gathering piece 21 and the second gathering piece 22 correspond to the wire harness P. Drive the mobile gathering mechanism 3 vertically to move so that the first gathering piece 21 and the second gathering piece 22 are located on both sides of the wire harness P. The first gathering piece 21 and the second gathering piece 22 on the mobile gathering mechanism 3 are closed together to gather the cables L at the winding front end of the wire harness P.

[0078] S4. Horizontally move the tape winding mechanism 4 so that it is attached to the wire harness P, entering the tape winding preparation state. Specifically, the gathered wire harness P is guided through the first notch 412 and the second notch 421 into the inner sides of the toothed ring 42 and the through-hole 411. Note that in the initial state, the rotational position of the toothed ring 42 is controlled so that the first notch 412 and the second notch 421 coincide. When the tape winding is complete and the wire harness P needs to be removed, the first notch 412 and the second notch 421 also need to align.

[0079] S5. Synchronously move the movable gathering mechanism 3 and the tape winding mechanism 4 in the length direction of the wire harness P. The movable gathering mechanism 3 gathers the cables L at the winding front end of the wire harness P in a movable manner, and the tape winding mechanism 4 winds the gathered wire harness P with tape.

[0080] After the above steps, the following steps are also included: after the mobile gathering mechanism 3 moves to the end of the wire harness P, the first gathering member 21 and the second gathering member 22 on the mobile gathering mechanism 3 can be separated first, and vertical and lateral movements are performed in sequence to separate the mobile gathering mechanism 3 and the wire harness P. At this time, the tape winding mechanism 4 can continue to move forward, thereby completing the tape winding at the end of the wire harness P.

[0081] When the end of the wire harness P is wound, the tape winding mechanism 4 first moves horizontally away from the wire harness P to make the wire harness P fall out, and then completes the tape cutting operation. The tape break adheres to the top surface of the support block 401, completing the positioning of the tape port, which is convenient for the next wire harness P winding operation.

[0082] Compared to existing methods, which rely solely on the tension of the tape itself to gather the cable L, this method leverages the synergy of fixed and mobile gathering mechanisms to implement static constraints and dynamic adjustments before and during winding. This method achieves spatiotemporal alignment of gathering and winding through synchronized motion control, effectively preventing secondary dispersion of the cable L during winding.

[0083] Through the above technical solution, the present application achieves the continuous and stable gathering of cables L during the winding process of the wire harness P, making the cross-sectional shape of the wound wire harness P closer to the ideal cylindrical shape. This method can improve the assembly compatibility of the wire harness P with the circular buckle, while reducing the local stress concentration caused by the irregular shape of the wire harness P on the tape, thereby improving the mechanical strength and fixing reliability of the wire harness P.

[0084] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
