Description

Technical Field

[0001] This utility model relates to the field of welding positioning fixture technology, and in particular to a soldering fixture that prevents solder adhesion and can position multi-angle wire harnesses. Background Technology

[0002] In the production process of American-style automotive wiring harnesses, the connection between the spring and the wire is usually achieved using a soldering process.

[0003] In existing technologies, simple tooling is often used for spot welding, which has the following significant drawbacks. First, tooling made of ordinary materials is prone to soldering at high temperatures, making it difficult to remove the welded wire harness from the tooling, affecting production efficiency and potentially damaging the product. Second, the existing tooling has a single positioning structure and cannot adapt to the welding needs of wire harnesses at different angles on the same tooling. Frequent tooling changes or manual positioning are required during operation, resulting in inaccurate positioning, cumbersome operation, low efficiency, and high defect rate.

[0004] Therefore, there is an urgent need for a soldering fixture that can effectively prevent solder adhesion and simultaneously meet the requirements for precise and rapid positioning of wire harnesses at various specific angles. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention aims to provide a soldering fixture that can effectively prevent solder sticking and simultaneously meet the requirements of precise and rapid positioning of wire harnesses at various specific angles.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wire harness soldering positioning fixture includes a fixture base and a fixture body fixed thereon by fasteners; the fixture body is made of synthetic stone; the upper surface of the fixture body is integrally formed with a plurality of positioning concave surfaces for positioning wire harnesses at different angles; the plurality of positioning concave surfaces include at least: a first positioning concave surface for positioning a ground wire spring and making the direction of the wire extension of the spring form an angle of approximately 90° with the horizontal plane; a second positioning concave surface for positioning a live wire spring and making the direction of the wire extension of the spring form an angle of approximately 45° with the horizontal plane; and a third positioning concave surface for positioning a neutral wire spring and making the direction of the wire extension of the spring form an angle of approximately 180° with the horizontal plane.

[0008] Preferably, the fastener is an internal hex screw.

[0009] Preferably, the first positioning concave surface, the second positioning concave surface, and the third positioning concave surface are arranged side by side on the upper surface of the tooling body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model integrates positioning concave surfaces with three specific angles of 90°, 45°, and 180° on the same tooling body, achieving multiple uses with one tooling, avoiding the trouble of frequently changing tooling, ensuring the accuracy and consistency of welding angles for wire harnesses of different specifications, and perfectly interpreting the innovation of multi-angle positioning.

[0012] This utility model uses synthetic stone material to manufacture the main body of the tooling. Utilizing the inherent high temperature resistance of synthetic stone, which can withstand temperatures above 300°C for a long time and does not wet or stick to solder, it solves the problem of solder sticking to the tooling, making the product easy to remove and greatly improving production efficiency and yield.

[0013] The anti-adhesion material and multi-angle positioning structure of this utility model support each other and together form an efficient solution, which significantly simplifies the soldering process, reduces the technical requirements for operators, saves time and labor costs, and has significant overall benefits.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] like Figures 1-2As shown, a wire harness soldering positioning fixture includes a fixture base 1 and a fixture body 2 fixed thereon by fasteners. The fixture body 2 is made of synthetic stone. The upper surface of the fixture body 2 is integrally formed with multiple positioning recesses for positioning wire harnesses at different angles. The multiple positioning recesses include at least: a first positioning recess 21 for positioning the ground wire spring and making the direction of the wire extension of the spring form an angle of approximately 90° with the horizontal plane; a second positioning recess 22 for positioning the live wire spring and making the direction of the wire extension of the spring form an angle of approximately 45° with the horizontal plane; and a third positioning recess 23 for positioning the neutral wire spring and making the direction of the wire extension of the spring form an angle of approximately 180° with the horizontal plane. The fasteners are hex socket screws 3. The first positioning recess 21, the second positioning recess 22 and the third positioning recess 23 are arranged side by side on the upper surface of the fixture body 2.

[0020] In a preferred embodiment of this utility model, the embodiment mainly consists of a tooling body 2, a tooling base 1, and hex socket screws 3. The tooling body 2 is fastened to the tooling base 1 by the hex socket screws 3.

[0021] The key to this embodiment lies in the material and structure of the tooling body 2:

[0022] Material: The main body of the tooling 2 is made of synthetic stone, which is precision-processed based on a composite material of glass fiber and high-temperature resistant resin. This material ensures that the tooling will not deform or be damaged at a soldering temperature of about 345℃, and its surface does not stick to the molten solder, achieving an automatic demolding effect and demonstrating anti-sticking characteristics.

[0023] Structure: Three independent positioning concave surfaces are integrally machined on the upper surface of the fixture body 2. The first positioning concave surface 21 is used to position the ground wire spring and make its conductor at approximately 90°. The second positioning concave surface 22 is used to position the live wire spring and make its conductor at approximately 45°. The third positioning concave surface 23 is used to position the neutral wire spring and make its conductor at approximately 180°. These concave surfaces are custom-made according to the shape of the corresponding spring to ensure that the position is unique and stable after being inserted. The soldering position is directly above them. The three concave surfaces are arranged side by side to realize the synchronous soldering support of multi-angle wire harnesses.

[0024] Work process:

[0025] When using, first bend and rivet the springs of the ground wire, live wire, and neutral wire to the corresponding wires to prefabricate the wire harness assembly;

[0026] Then, the assembled soldering fixture is firmly installed on the worktable of the soldering equipment through the mounting holes on the fixture base 1. The soldering equipment is adjusted and the soldering head is moved so that its tip can be accurately aligned with the soldering position of any desired soldering station on the fixture body 2. According to the process requirements, the soldering temperature is set to 345℃ and the soldering time is set to 2 seconds.

[0027] Then, according to production needs, the operator inserts the prefabricated ground wire harness assembly into the first positioning recess 21, the live wire harness assembly into the second positioning recess 22, or the neutral wire harness assembly into the third positioning recess 23. Due to the precise matching between the concave surface and the spring shape, the harness assembly can be quickly and accurately positioned under its own weight or slight pressure without the need for additional angle adjustment.

[0028] Then start the soldering equipment. The solder head moves along the preset trajectory to the solder position above the wire harness that has been secured. Press down and feed out the solder wire. Perform a soldering operation at a temperature of 345℃ for 2 seconds. Excess solder produced during the soldering will not stick to the surface of the tool body 2 made of synthetic stone.

[0029] After soldering is completed, the solder head is lifted, and the operator can easily remove the soldered wire harness assembly from the positioning recess without having to knock or pry it, effectively avoiding product damage or tooling cleaning caused by adhesion. Finally, the removed wire harness is inspected for appearance quality.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
