Embodiment 1

[0033] A method for preparing a wire harness, the processing steps of which are as follows:

[0034] 1. Wiring and positioning: Carry out wiring on a professional positioning fixture according to the process requirements. The number of wiring groups is two groups. After the wiring is qualified, the positioning can be completed. The wiring of two groups of wires 1 can be completed at one time, such as figure 1 shown.

[0035] 2. Laser and half-stripping: According to the process requirements, calculate the laser size and half-stripping size of multiple groups of wires 1, determine the position of the laser, and use the laser machine to laser multiple groups of wires 1 at one time; place the multiple groups of wires 1 that have been lasered in half Positioning in the stripping area, and then half-stripping the outer sheath 6 and the isolation layer of the wire 1 through the half-stripping machine (the isolation layer is a layer inside the outer sheath 6), forming the first laser...

Embodiment 2

[0042] Such as Figure 7 Shown is the welding head 7 for welding the ground sheet 3, the welding head 7 includes two welding parts 71, the welding surface of each welding part 71 is provided with a coating structure for welding the wire 1, the coating structure includes several continuous concave The number and shape of the groove 72 and the groove 72 match the wire rod, meeting the requirements of welding. During welding, the cladding structure of the welding head 7 is directly in contact with the wire rod 1 for welding, the welding head 7 and the lower welding head 8 work at the same time, and the lower welding head 8 is a flat welding head, which jointly completes the welding of the grounding piece 2, as Figure 7 shown. Similarly, welding of 3 groups, 4 groups or more than 4 groups can be carried out at one time. The number of corresponding welding parts 71 is set to be the same as the number of groups, and the positioning jig is provided with wiring grooves corresponding...

Embodiment 3

[0044] The rest are the same as in Embodiment 1, except that the half-stripped size of the wire 1 is 2.0±0.5mm.

Abstract

The invention discloses a preparation method of a wire harness. The preparation method comprises the processing steps of 1, wiring, that is, carrying out wiring and positioning on a professional positioning gauge, wherein the number of wiring and positioning groups is multiple; 2, laser radiation and half-stripping, that is, calculating the radiation size and the half-stripping size of the multiple groups of wires, determining the laser radiation position, carrying out laser radiation on the multiple groups of wires in one time, and then carrying out half-stripping on the wires; 3, grounding piece welding; 4, secondary laser radiation, secondary half-stripping and tin plating, that is, carrying out secondary laser radiation on the wires, completing secondary half-stripping and plating tin; 5, connector welding; and 6, reinforcing, that is, carrying out dispensing reinforcement on a welding point after the connector welding is finished, thereby completing the preparation of the whole wire harness. Multiple wire harnesses can be welded in one time by adopting the wire harness preparation method provided by the invention, thereby improving the production efficiency of the wire harnesses greatly.

Description

technical field [0001] The invention relates to the field of wire harnesses, in particular to a method for preparing wire harnesses. Background technique [0002] The wiring harness, as the name suggests, is the wiring part connected to the electrical equipment in the circuit, which can realize the connection of signals and power between the carrying equipment. [0003] With the continuous improvement of people's requirements for comfort, economy and safety, the types of electronic products are also increasing. To realize the signal connection or power connection between various electronic products, wiring harnesses are needed. [0004] At present, in the production process of the wire harness, only one welding can be realized, and multiple wire harnesses cannot be welded at the same time, and the production efficiency of the wire harness cannot be improved. Contents of the invention [0005] In order to solve the above-mentioned technical problems, the object of the pres...
