Problems solved by technology

[0003]However, during the long-term processing of the existing technology, it is found that there are still certain disadvantages: 1. The existing automatic tape wrapping equipment is often only suitable for a single The tape of the wiring harness is wound, and there are many types of wiring harnesses in the vehicle, including wiring harnesses with cross or triangular connectors, which also account for a large proportion. For this type of wiring harness, manual winding of tape is usually used, resulting in the outside of the wiring harness. Corrugated pipes often have uneven tape winding, or even missing winding and missing wires; 2. The side branch line harness at the end of the corrugated pipe near the branch node cannot be stably limited, and the winding process is accompanied by large shaking and pulling. It is easy to cause the circuit connection at the node connection to be loose or even disconnected

Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] Such as Figure 1 to Figure 6 As shown in the figure, a two-way twisting process for a complete vehicle wiring harness corrugated tube includes the following steps:

[0025] S1: Pre-winding treatment: The tape-wrapping position of the vehicle harness includes cross-shaped or triangular branch nodes and branch lines. First, wrap the branch line positions at the end of the branch nodes on the harness with PVC / cloth tape for 2 tape widths, and then Install bellows on the wrapped tape to prevent scratching the wires;

[0026] S2: Positioning and installation of wiring harness: install the wiring harness of the whole vehicle with bellows installed on the branch line on the positioning frame 2, and fix the positioning frame 2 with a snap joint, ...

Abstract

The invention discloses a whole vehicle wire harness corrugated pipe bidirectional pattern winding process, and relates to the technical field of automobile wire harness manufacturing. The process comprises the following steps: winding pretreatment, wire harness positioning installation, corrugated pipe bidirectional flexible winding of adhesive tape, adhesive tape head shearing, and shutdown unloading. A shaping plate and an elastic compression roller are arranged on the positioning frame, and the winding mechanism is arranged on the rack, so that a bidirectional flexible winding mode and a staggered winding and overlapping density changing flexible winding mode are formed on the corrugated pipe, complete winding of the corrugated pipe can be ensured, and the situation of missing winding or line leakage is avoided; and the adhesive tape close to the branch node is wound and covered more densely, so that the firmness degree of the node connecting part is ensured under the state that the corrugated pipe shakes and is pulled, and the condition that the circuit connection at the node connecting part is loosened and even broken is avoided.

Description

technical field [0001] The invention relates to the technical field of automobile wire harness manufacturing, in particular to a bidirectional flower winding process for a complete vehicle wire harness corrugated tube. Background technique [0002] There are many electrical parts in the car, and most of the parts are connected by car wiring harnesses, connectors and outer wrapped tapes, which are used to stably transmit electrical signals and ensure the reliability of the connecting circuit. The outer wrapped tapes are used to supply electronic and electrical components The specified current value prevents electromagnetic interference to the surrounding circuits, eliminates electrical short circuits, and makes the layout of the wiring harness more compact. The existing vehicle wiring harness is tape-wrapped on the wiring harness jacket bellows. Usually, full-wrapping, The winding method of interval winding and flower winding. [0003] However, in the long-term processing of...
