Technical Field

[0001] The utility model relates to the technical field of wire harness processing, in particular to a wire harness carrying mechanism. Background Art

[0002] Wire harnesses are an important component in automobile manufacturing and are responsible for connecting various electrical and electronic equipment. In order to improve the processing efficiency of wire harnesses, the existing technology often uses multiple stations to perform automated operations such as stripping, crimping, and shell insertion on the wire harnesses. During the automated processing of cables, the wire harnesses need to be clamped and gradually transferred to the next station.

[0003] In the prior art, an automatic circulation line is often used to achieve the clamping and transfer of the wire harness. For example, the Chinese invention patent application with publication number CN111252490A disclosed an automated equipment circulation device on June 9, 2020, which realizes the movement of the wire harness carrier through two parallel synchronous belts and guide rails parallel to the synchronous belts, and completes the circulation movement and transmission of the carrier through two vertical transfer mechanisms arranged at both ends of the synchronous belts.

[0004] However, the above-mentioned method of using a loop line requires the carrier to be transferred between two synchronous belts, which is not only time-consuming, but also makes the wiring harness transport mechanism occupy a large area, which is not conducive to miniaturization design. Utility Model Content

[0005] In view of at least one of the above technical problems, the utility model provides a wire harness transport mechanism, which adopts structural improvement to reduce the space occupied by the wire harness transport mechanism.

[0013] Furthermore, the feed drive assembly also includes a synchronous belt, the drive motor is arranged in parallel with the screw rod, and the synchronous belt is connected between the drive motor and the screw rod to drive the rotation of the screw rod.

[0014] Furthermore, the wire clamping assembly includes a height adjustment assembly connected to the nut seat and a clamping member connected to the height adjustment assembly.

[0015] Furthermore, the clamping member is a cylinder clamp.

[0016] Furthermore, the height adjustment assembly includes a support frame fixed on the nut seat, a vertical movable member passing through the support frame and connected to the clamping member, and an adjustment bolt with one end rotatably connected to the vertical movable member and the other end screwed on the support frame.

[0017] Furthermore, the wire-supporting mechanism is provided with two wire-supporting rods which can be moved closer to or farther away from each other, and the tops of the wire-supporting rods form a closed area for the wire harness to pass through.

[0018] Furthermore, the tops of the two support rods have semicircular structures arranged toward each other.

[0019] Furthermore, the tops of the two supporting rods are bent toward each other, and the two supporting rods also pass through a horizontally arranged guard plate, so that the guard plate and the tops of the two supporting rods form a closed area for the supporting wire.

[0020] The beneficial effects of the utility model are as follows: the utility model utilizes the movement of the mover on the linear motor and fixes the bracket and the wire harness clamping and feeding mechanism on the mover to realize the movement of the wire harness clamping and feeding mechanism driven by the mover.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. 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 related listed items.

[0029] like Figures 1 to 4 The wire harness transport mechanism shown in the figure comprises a linear motor 1, a bracket 2, a wire harness clamping and feeding mechanism 3 and a wire supporting mechanism 4; wherein, Figure 1As shown in the figure, the linear motor 1 is a prior art. The working principle of the linear asynchronous motor is the same as that of the rotary asynchronous motor. The stator winding is connected to the AC power supply. After the multi-phase AC current is passed, a stable traveling wave magnetic field is generated in the air gap. The magnetic field moves linearly along the air gap. At the same time, an electromotive force is induced in the conductor of the mover 11, and a current is generated. This current interacts with the traveling wave magnetic field to generate an asynchronous driving force, so that the mover 11 moves linearly along the traveling wave direction. The linear motor 1 has at least one mover 11; in an embodiment of the utility model, the mover 11 moves along a linear direction, and the number of movers 11 can be set according to the needs of the workstation; a bracket 2 is fixed on the mover 11; a wire harness clamping and feeding mechanism 3 includes a feed drive assembly 31 fixed on the bracket 2 and a wire clamping assembly 32 fixed on the driving end of the feed drive assembly 31, and the driving direction of the feed drive assembly 31 is perpendicular to the moving direction of the mover 11; a wire supporting mechanism 4 is arranged on a side of the bracket 2 away from the feed drive assembly 31, and the clamping center of the wire supporting mechanism 4 is arranged colinearly with the clamping center of the wire clamping assembly 32.

[0030] In the above embodiment, the mover 11 on the linear motor 1 is utilized to move, and the bracket 2 and the wire harness clamping and feeding mechanism 3 are fixed on the mover 11, so that the mover 11 drives the wire harness clamping and feeding mechanism 3 to move. Compared with the prior art, the reciprocating movement of the stator reduces the space occupied by clamping and transferring the wire harness, and the provision of the wire supporting mechanism 4 also improves the reliability of the wire harness during movement.

[0031] On the basis of the above embodiments, in some embodiments of the present invention, a plurality of movers 11 are provided, and the plurality of movers 11 are arranged at intervals. It should be noted here that the intervals between the movers 11 are adapted to the intervals between the workstations, so that the synchronous operation of the plurality of workstations can be realized; when one round of operation is completed, the movers 11 are reset to realize the next round of continued operation.

[0032] Alternatively, if Figure 2 As shown in the figure, the feed drive assembly 31 includes a drive motor 31a, a screw rod 31b connected to the drive motor 31a, a guide rail 31c arranged parallel to the screw rod 31b, and a nut seat 31d slidably connected to the guide rail 31c, and the clamping assembly 32 is fixed on the nut seat 31d. It should be pointed out here that the connection between the drive motor 31a and the screw rod 31b can be a direct connection or a slidable connection. Figure 2 As shown in , the feed drive assembly 31 also includes a synchronous belt 31e, the drive motor 31a is arranged in parallel with the screw rod 31b, and the synchronous belt 31e is connected between the drive motor 31a and the screw rod 31b to drive the rotation of the screw rod 31b. By setting the synchronous belt 31e, the overall length of the feed drive assembly 31 is reduced, and the space occupied by the entire wire harness carrying mechanism can be further reduced.

[0033] Alternatively, if Figure 3 As shown in the figure, the wire clamping assembly 32 includes a height adjustment assembly 32a connected to the nut seat 31d and a clamping member 32b connected to the height adjustment assembly 32a. By setting the height adjustment assembly 32a, it is possible to adapt to the operation requirements of more different workstations, that is, the clamped wire harness can move along the linear arrangement direction of the workstation, and can also move toward or away from the workstation. In addition, the height can be adjusted in the height direction; of course, it should be pointed out here that there are many ways to adjust the height, such as being driven by a cylinder or a hydraulic cylinder.

[0034] In some embodiments of the present invention, the clamping member 32b has various structural forms, for example, the clamping member 32b is a cylinder clamp. The cylinder clamp is a prior art and will not be described in detail here. The clamp can be set as a V-shaped clamp to adapt to the clamping of wire harnesses of various specifications.

[0035] Alternatively, if Figure 3 As shown in the figure, the height adjustment assembly 32a includes a support frame 32a1 fixed on the nut seat 31d, a vertical moving member 32a2 passing through the support frame 32a1 and connected to the clamping member 32b, and an adjusting bolt 32a3 with one end rotatably connected to the vertical moving member 32a2 and the other end screwed on the support frame 32a1. By such an arrangement, when the height needs to be adjusted, the height of the clamping member 32b can be adjusted and fixed by simply rotating the bolt.

[0036] In some embodiments of the present invention, Figure 3 As shown in , the wire-supporting mechanism 4 has two wire-supporting rods 41 that can move closer to or farther away from each other, and the top of the wire-supporting rods 41 forms a closed area for the wire harness to pass through. The function of the wire-supporting mechanism 4 is to prevent the unclamped end of the wire harness from bending when the mover 11 moves, so as to avoid entanglement between the wire harnesses; the driving of the wire-supporting rods 41 can also be achieved by a cylinder, etc.; in some embodiments of the utility model, the specific structure of the wire-supporting rods 41 can be that the tops of the two wire-supporting rods 41 have a semicircular structure arranged toward each other. By such a setting, the two wire-supporting rods 41 are close to each other to form a circular wire-supporting structure, so that when the wire-supporting mechanism 4 moves synchronously with the mover 11, the straightness of the wire harness can be maintained.

[0037] In another wire-supporting method of the present invention, as Figure 4 As shown in FIG. 1 , the tops of the two support rods 41 are bent toward each other, and the two support rods 41 also pass through a horizontally arranged guard plate 42, so that the guard plate 42 and the tops of the two support rods 41 form a closed area for the support. Figure 4In an embodiment of the utility model, a straight hole is provided on the guard plate 42 which is parallel to the moving direction of the mover 11, and the top intersection parts of the two wire guide rods 41 pass through the straight hole, so that a closed area is formed between the lower side of the intersection part of the wire guide rods 41 and the upper surface of the wire guide plate. After the wire harness passes through the area, it can be overlapped on the guard plate 42 at the same time, thereby further improving the straightness of the wire harness when moving and avoiding excessive bending of the wire harness.

[0038] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention.
