Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of intelligent manufacturing, and particularly relates to an automatic wire harness commutation device and method. Background Art
[0002] Wire harness commutation is a key process in intelligent wire harness manufacturing, which refers to the operation of orienting and adjusting the spatial attitude of the wire harness according to process requirements when terminals are punched or connectors are installed at both ends of the wire harness. During wire harness production, it is often necessary to transfer between multiple workstations, and there are spatial angle differences in the installation positions of terminals at both ends. During the commutation process, the clamping mechanism needs to precisely control the spatial position and attitude of the wire harness to ensure that the axial length retained at the clamping end of the wire harness after commutation is exactly the same as that before commutation. If the length consistency does not meet the standard, it will lead to problems such as the offset of the terminal crimping position and wire harness assembly interference in subsequent processes, directly affecting the product qualification rate.
[0003] In the prior art, the commutation operation of wire harnesses usually relies on manual or traditional mechanical equipment to complete. During the commutation process, after one end of the wire harness is processed, the wire harness needs to be flipped or rotated to continue processing the other end. Due to the lack of an accurate automatic control system, during the commutation operation, the reserved lengths at both ends of the wire harness often cannot be kept consistent, and this inaccuracy in length will directly affect the work at the next workstation. This error usually needs to be compensated by manual inspection and adjustment, increasing the complexity and cost of production and also reducing the production efficiency. Therefore, there is still a large room for improvement in the accuracy and automation level of wire harness commutation equipment in the prior art.
[0004] Therefore, there is an urgent need for a solution that can improve the technical problems existing in the prior art, and reduce the error during wire harness commutation through structural improvements to improve the production efficiency of wire harnesses. Summary of the Invention

[0011] In some embodiments of the present invention, when the jaw assembly is close to the base, the position of the jaw assembly is lower than the position of the first clamping member.
[0012] In some embodiments of the present invention, when the first clamping member is close to the base, the position of the first clamping member is lower than the second clamping member.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0023] As Figures 1 to 7 shown, the automatic wire harness commutation device includes: Base 1; Frame 2, which is slidably arranged on the base 1 and can move relatively closer to or away from the wire harness 01 processing station. The frame 2 has a sliding plate 21 that can move relatively closer to or away from the base 1. The frame 2 can slide relative to the position on the base 1, move closer to or away from the station direction, and can also move up and down. The commutation of the wire harness 01 is carried out by rotation. The frame 2 with displacement drives the wire harness 01 away from the station, and the rotation of the wire harness 01 will not affect the station, preventing the wire harness 01 from hitting the structure on the station when rotating. It should be noted here that the frame 2 can first move away from the station and then away from the base 1; or first move away from the base 1 and then away from the station; or move away from the base 1 and the station at the same time. The specific working mode is set according to actual needs. It should also be noted that there are many types of sliding structures, which can be a linear slide rail structure, a roller sliding structure, a chute and slider structure, or other sliding structure forms.
[0024] The rotating mechanism 3 includes a rotation driving member 31 fixedly connected to the sliding plate 21, and a rotating member 32 disposed toward the base 1 and connected to the rotation driving member 31; the rotation of the rotating mechanism 3 drives the rotation of the wire harness 01, so that the wire harness 01 can rotate from the initial angle to different angles to prepare for entering the next station for processing. It should be noted here that there are many forms of the rotating structure, which can be driven by a motor, pneumatically, or hydraulically, etc.
[0025] The clamping mechanism 4 is disposed toward the base 1 and fixedly connected to the rotating member 32, and includes a first clamping member 41 and a first driving member 42 for driving the first clamping member 41 to open and close; the wire harness 01 is clamped and fixed by the clamping mechanism 4, and the clamping mechanism 4 is rotated by the rotating mechanism 3 to rotate the wire harness 01 so that the wire harness 01 rotates to a specified angle. It should be noted here that there are many forms of the clamping mechanism 4, which can be mechanical clamping, pneumatic clamping, hydraulic clamping, or other forms of clamping.
[0026] The wire pulling mechanism 5 is fixedly arranged on the base 1 and includes a wire pulling displacement member 51 whose displacement direction is parallel to the opening extension direction of the first clamping member 41, a second clamping member 52 arranged on the wire pulling displacement member 51, and a second driving member 53 for driving the second clamping member 52 to open and close. Before and after the wire harness 01 rotates, the lengths of both ends of the wire harness 01 will be different. The wire pulling mechanism 5 elongates one end of the wire harness 01 to be processed to a set length. After the rotation is completed, the wire pulling mechanism 5 pulls the wire harness 01, and the wire pulling mechanism 5 can be accurately controlled.
[0027] As Figure 1 shown, the automatic wire harness 01 commutation device provided by the present invention solves the problem of insufficient accuracy in the wire harness 01 commutation process in the prior art by precisely controlling the spatial pose of the wire harness 01. The present invention adopts the collaborative design of the sliding plate 21 and the rotating mechanism 3, which can ensure that the reserved lengths at both ends of the wire harness 01 are the same, thus avoiding errors caused by manual adjustment; the present invention has a high degree of automation, can reduce manual intervention, improve production efficiency, and significantly improve the product qualification rate; the design of the present invention enables it to have strong adaptability, can be flexibly adjusted according to the needs of different stations, and improves the flexibility and versatility of the production line. The present invention optimizes the wire harness 01 commutation process through a simple and efficient structural design, improving production accuracy and efficiency.
[0028] When the wire harness 01 is too long, the phenomenon of the wire harness 01 sagging will occur when the wire harness 01 is clamped. The wire harness 01 is not in a straight line, and the position will shift when the wire harness 01 is pulled. To keep the position of the wire harness 01 unchanged during the wire pulling process of the wire harness 01, as Figure 6As shown, there is also a wire feeding mechanism 6, which is arranged between the rotating mechanism 3 and the sliding plate 21, and includes a jaw assembly 61 and a jaw driving member 62 for driving the jaw assembly 61 to open and close. The jaw assembly 61 has the same opening extension direction as the first clamping member 41. When the wire harness 01 is relatively long, the wire feeding mechanism 6 lifts the wire harness 01 to the same height as the first clamping member 41, effectively avoiding the position deviation of the wire harness 01 during the pulling process. The wire feeding mechanism 6 ensures that the wire harness 01 always maintains the correct posture and stable position during the entire commutation process, avoiding inaccurate clamping or misoperation caused by the position change of the wire harness 01, thereby improving the accuracy and stability of the commutation process. It not only reduces the error caused by the deviation of the wire harness 01, but also ensures the accuracy of the subsequent processes, and thus improves the production efficiency and product quality.
[0029] The function of the wire feeding mechanism 6 is to correct the position of the wire harness 01. To enable the wire harness 01 to move relatively in the wire feeding mechanism 6, as Figure 6 shown, the jaw assembly 61 includes a first jaw 61a and a second jaw 61b that can open and close relatively. When the first jaw 61a and the second jaw 61b are combined, there is an accommodation space 63 for accommodating the wire harness 01 in the middle. The jaw assembly 61 is designed with a first jaw 61a and a second jaw 61b that can open and close relatively. When the two are combined, a space for accommodating the wire harness 01 is formed, mainly playing the role of supporting the wire harness 01, rather than directly clamping the wire harness 01. The jaw assembly 61 can stably support the wire harness 01, prevent the wire harness 01 from shifting or tilting during the pulling process, ensure the stability of the wire harness 01 during the commutation process, contribute to improving the accuracy of wire harness 01 processing, avoid inaccurate clamping or misoperation caused by the position change of the wire harness 01, thereby improving the production efficiency and product quality. The flexible opening and closing of the jaw design enables it to adapt to wire harnesses 01 of different lengths and specifications, enhances the adaptability and versatility of the equipment, optimizes the stability of the wire harness 01 and the clamping process, and improves the reliability and operation efficiency of the equipment.
[0030] In some embodiments of the present invention, as Figure 5 shown, the wire feeding mechanism 6 further includes a wire feeding sliding member 64 fixedly connected to the sliding plate 21. The wire feeding sliding member 64 drives the jaw assembly 61 to move relatively closer to or farther away from the base 1.
[0031] To prevent the wire harness 01 from contacting and colliding with the jaw assembly 61 when rotating, as Figure 4 shown, when the jaw assembly 61 is away from the base 1, the position of the jaw assembly 61 is higher than the position of the first clamping member 41.
[0032] To pull the downwardly bent wire harness 01 to the same height as the first clamping member 41, as Figure 5 shown, when the jaw assembly 61 is close to the base 1, the position of the jaw assembly 61 is lower than the position of the first clamping member 41.
[0033] Before the rotation of the wire harness 01 is completed, the wire guiding mechanism 6 does not need to support the wire harness 01. The first clamping member 41 clamps the wire harness 01 and rotates it. To prevent the rotation of the wire harness 01 from hitting other components and structures, the wire guiding mechanism 6 rises to a position away from the base 1. After the rotation of the wire harness 01 is completed, the longer end of the wire harness 01 is located between the first clamping member 41 and the sliding plate 21. The wire guiding mechanism 6 opens, moves to below the wire harness 01, closes the wire guiding mechanism 6, places the wire harness 01 in the accommodation space 63, pulls the wire harness 01 upward, and pulls the wire harness 01 to the same height as the first clamping member 41. This effectively improves the stability of the wire harness 01 during the commutation process, ensures that the wire harness 01 does not shift or tilt in position, and avoids errors caused by unstable positions.
[0034] As Figure 2 shown, to ensure that the wire harness 01 on the clamping station of the first clamping member 41 is not affected in the initial position, the first clamping member 41 can extend to the station. When the first clamping member 41 approaches the base 1, the position of the first clamping member 41 is lower than that of the second clamping member 52. During the handover process of the wire harness 01 from the production station to the rotating mechanism 3, interference with other stations or equipment is avoided. The height difference between the first clamping member 41 and the second clamping member 52 makes the movement of the clamping members on the station more flexible, and avoids collisions and interferences when clamping or placing the wire harness 01.
[0035] In some embodiments of the present invention, the rotation plane of the rotating member 32 is parallel to the base 1, and the rotation angle of the rotating member 32 is 0° - 180°. The design of 0° - 180° improves the flexibility and adaptability of the equipment, enabling it to flexibly adjust the rotation angle according to different stations and the requirements of the wire harness 01, optimizing the accuracy and stability during the commutation process of the wire harness 01, ensuring that the wire harness 01 maintains the correct position during rotation, and avoiding offsets caused by asymmetric angles or rotation errors. By simplifying the structure, the equipment is more stable and easier to maintain, reducing the complexity of design and manufacturing. At the same time, the rotation angle range of 0° - 180° enables the equipment to operate efficiently in a limited space, improving the layout efficiency of the overall production line.
[0036] During the rotation of the longer wire harness 01, due to the centrifugal force of rotation, the wire harness 01 may fly up. To prevent the rotating wire harness 01 from affecting the operation of other mechanisms, as Figure 7As shown, the base 1 is also provided with a baffle 7, and the baffle 7 is arranged on the side of the rotating mechanism 3 and the clamping mechanism 4 away from the wire pulling mechanism 5. The baffle 7 can effectively prevent the rotating mechanism 3 and the clamping mechanism 4 from interfering with the wire pulling mechanism 5 during operation, ensure the independent movement of each mechanism, reduce the mutual influence, improve the stability and safety of the equipment, avoid the collision or friction between mechanical components, thereby enhancing the reliability of the overall equipment. The setting of the baffle 7 helps to optimize the layout of the working space, ensure the smooth movement of each part of the equipment, and improve the production efficiency and operation accuracy.
[0037] According to the second aspect of the present invention, there is also provided an automatic wire harness 01 commutation method, as Figure 8 shown, including the following steps: S10: The clamping mechanism 4 grabs the wire harness 01; S20: The clamping mechanism 4 moves simultaneously away from the base 1 and the working position direction, and the rotating mechanism 3 rotates; S30: After rotation is completed, the clamping mechanism 4 returns to the initial position; S40: The wire supporting mechanism 6 lifts the wire harness 01; S50: The wire pulling mechanism 5 pulls the wire harness 01 to a set length.
[0038] As Figure 2 shown, the clamping mechanism 4 extends to the working position, clamps the wire harness 01 on the working position and pulls it back. As Figure 3 shown, while pulling back, the clamping mechanism 4 and the rotating mechanism 3 move simultaneously, and the wire harness 01 rotates away from the working position and rotates by an angle. As Figure 4 shown, the wire harness 01 rotates in the air to a set angle. As Figure 5 shown, then it falls back to the same height as the wire pulling mechanism 5, the wire supporting mechanism 6 lifts the longer wire harness 01 to the same height as the clamping mechanism 4, and finally the wire pulling mechanism 5 pulls the wire harness 01, pulls the other end of the wire harness 01 that needs to be processed to a set length, and then sends the wire harness 01 to the working position, and operates in this cycle.
