Description

Technical Field

[0001] The invention relates to the field of wire harness production, and in particular to a wire harness production process. Background Art

[0002] Electrical components need to be electrically connected or transmit signals through wire harnesses. Currently, most wire harness production uses wire harness equipment for automated production, which can effectively improve wire harness production efficiency and reduce production costs. However, the current automated wire harness production equipment is only suitable for the production of thinner wires, and is less suitable for the production of thicker wires. In addition, during the wire harness production process, the ends of the wire harness need to be tinned. Before the tinning treatment, the wire harness needs to be dipped in flux. The traditional method of dipping in flux easily leads to uneven distribution of flux at the ends of the wire harness, affecting the quality of the tinning treatment. Summary of the invention

[0003] The object of the present invention is to provide a wire harness production process, which can be used for the automated production of wire harnesses with relatively large thickness.

After the tinning treatment, the prepared wire segment is unloaded by a unloading mechanism to obtain the wire; The thickness of the wire is such that the wire segments obtained by the cutting process will not bend in a naturally suspended state. The wire segments after the cutting process are transported by a transfer mechanism, and the transfer mechanism transports the wire segments to a peeling mechanism, an additive dipping mechanism, and a tinning mechanism for corresponding processing.

DETAILED DESCRIPTION

[0028] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0029] As used herein, the terms "parallel," "perpendicular," and the like are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0030] like Figure 1 , 12A wire harness production process is shown, comprising the following operations performed on a wire harness production device: S1: unwinding the wire through a wire unwinding mechanism 10, and peeling the end of the wire, and performing terminal treatment on the peeled end; S2: cutting the terminal-treated wire into wire segments 01, peeling the other end of the wire segment 01, and then performing a dipping agent treatment and a tinning treatment on the other end of the wire segment 01 in sequence, and after the tinning treatment, unloading the prepared wire segment 01 through a discharging mechanism 80 to obtain the wire; The thickness of the wire is such that the wire segment 01 obtained by the cutting process will not bend in a naturally suspended state. The wire segment 01 after the cutting process is transported by a transfer mechanism 50, and the transfer mechanism 50 transports the wire segment 01 to the peeling mechanism 30, the dipping agent mechanism 60, and the tinning mechanism 70 for corresponding processing.

[0031] In step S1, the wire-releasing mechanism 10 is installed on the first movable mounting seat 11, and the first movable mounting seat 11 is adjusted to move so that the wire-releasing mechanism 10 is arranged corresponding to the peeling mechanism 30, the terminal crimping mechanism 20 and the cutting mechanism 40 for corresponding processing.

The guide auxiliary wheels 14 are arranged at intervals along the length direction of the belt body section. During specific operation, the pulleys and the guide auxiliary wheels 14 are both toothed pulleys, and the conveyor belt body is a (single-sided) toothed conveyor belt.

The first clamping conveyor belt 12 and the second clamping conveyor belt 13 are adjusted to move to extend or retract the wire, so as to adapt to the different processing requirements of the wire and the requirements for convenient and fast transportation between various processing stations. Specifically, the movement of the first movable mounting seat 11 and the first bracket 17 can be adjusted by means of a pneumatic cylinder or an electric cylinder, and the technicians can select the corresponding model for assembly and use according to actual needs.

[0037] like Figure 5 As shown, an upper movable mounting bracket 31 and a lower movable mounting bracket 32 ​​are arranged correspondingly on the upper and lower sides of the frame 00. The upper movable mounting bracket 31 and the lower movable mounting bracket 32 ​​are both slidably mounted on the frame 00 along the vertical direction.

During the specific operation, the unloaded wire segment 01 is arranged along the Y direction, and the first unloading transmission wheel 87 and the second unloading transmission wheel 86 both use toothed belt wheels, and the unloading transmission belt can be a (single-sided) toothed conveyor belt. The first unloading transmission wheel 87, the second unloading transmission wheel 86, and the unloading transmission belt are set so that when the unloading pneumatic finger 81 moves, it can rotate itself to meet the posture requirements of the wire segment 01 during unloading. The unloading drive component can be specifically composed of a drive motor. The above scheme can reliably realize the convenient and fast unloading of the wire segment 01, and can meet the unloading requirements of the corresponding posture. The implementation of the two unloading jaws 82 can be consistent with the implementation of the first jaw 51 and the second jaw 52.
