Description

Technical Field

[0001] This utility model relates to wire harness processing equipment technology, specifically to a wire harness core stacking welding device for pressing and welding multiple strands of dispersed wire cores into a block-shaped integral structure. Background Technology

[0002] In wire harness manufacturing for automobiles, home appliances, and industrial equipment, the welding of multi-strand wires is a critical process, as its quality directly affects the wire harness's conductivity, mechanical strength, and service life. Currently, existing wire harness core welding equipment suffers from the following technical challenges in practical applications:

[0003] Low core positioning accuracy and poor forming consistency: Existing equipment mostly uses fixed blocks to limit the position of multiple dispersed cores. It cannot flexibly adjust the limiting space according to the changes in the number of cores and diameter. This easily leads to problems such as core offset and uneven stacking before welding. Ultimately, the welded cores are irregular in shape and do not meet the assembly requirements of the block structure. Secondary shaping is required, which increases processing costs and time.

[0004] Uneven welding pressure leads to unstable welding quality: Existing welding mechanisms mostly use rigid connections between the upper and lower electrodes, making it impossible to adaptively adjust the pressure according to the actual stacking thickness of the wire cores during the welding process. When there is a slight deviation in the stacking of the wire cores, excessive pressure from the electrodes on local wire cores can easily damage them, while insufficient pressure can lead to poor contact between the wire cores, resulting in incomplete or false welds, which reduces the conductivity and mechanical strength of the wire harness.

[0005] Post-welding material removal is difficult and can easily damage the workpiece and equipment: After the wire core is welded, it is easy for it to slightly stick to the electrode due to high temperature. Existing equipment lacks a dedicated material removal structure, and it usually needs to be manually peeled or pried with external tools. This is not only inefficient, but may also cause deformation of the square wire core after welding, wear on the electrode surface, shorten the service life of the equipment, and increase the safety risks of manual operation.

[0006] To address the shortcomings of the existing technologies, there is an urgent need to design a wire harness core stacking and welding device with precise positioning, adaptive pressure welding, and efficient material removal functions, in order to solve problems such as poor core forming, unstable welding quality, and difficulty in material removal.

[0015] The preferred technical solution is that both the first limiting block and the second limiting block are made of high-temperature resistant ceramic material.

[0035] Workflow of wire harness core stacking and welding device

[0036] 1. Core placement: In the initial state, the second limiting block of the left and right limiting mechanism of the core is in a position away from the first limiting block under the action of the first telescopic cylinder, and the multiple strands of dispersed core are placed on the floating seat and located between the first limiting block and the second limiting block (corresponding to the area directly above the first electrode).

[0037] 2. Left and right positioning of the wire core: Start the telescopic cylinder one, which drives the limit block two to move closer to the limit block one in the left and right direction until the two limit blocks clamp the wire core, so as to achieve precise horizontal positioning of the wire core;

[0038] 3. Top and bottom pressure welding of wire core: Start the telescopic cylinder two of the top and bottom pressure welding mechanism of wire core, which drives electrode two to move downwards and approach electrode one in the vertical direction. After electrode two contacts the wire core, continuous pressure is applied. The floating seat floats adaptively up and down through the cooperation of guide column and spring to ensure uniform pressure. At the same time, the external welding equipment is energized through electrode one and electrode two to complete the pressure welding of wire core and form a block-shaped whole.

[0039] 4. Material removal and resetting: After welding is completed, start the telescopic cylinder two to drive electrode two to reset upward. At the same time, start the telescopic cylinder three to drive the pad block to slide along the guide rail, push the floating seat to move upward, and then reset, so that electrode one and electrode two are separated from the wire core; finally, the telescopic cylinder one drives the limit block two to reset, and the welded wire core is taken out, completing one work cycle.

[0040] Therefore, this utility model has the following advantages:

[0041] The technical solution of this invention provides a precise solution to the pain points of the prior art, and its technical effects are highly consistent with the technical problems of the technical solution and the background art, as detailed below:

[0042] To address the issue of low core positioning accuracy and improve molding consistency: The adjustable design of the limit block driven by the telescopic cylinder allows for flexible adjustment of the limit space based on the number of core strands and diameter. Combined with the smooth surface of the ceramic limit block, this achieves precise horizontal positioning of multiple core strands, reduces the dimensional deviation of the square core strands after welding, improves molding consistency, and eliminates the need for secondary shaping.

[0043] To solve the problem of uneven pressure during pressure welding and improve welding quality: The floating seat achieves adaptive up-and-down floating through the cooperation of springs and guide posts. During the pressure application process of electrode two, the height can be automatically adjusted according to the actual thickness of the wire core stack, ensuring that electrode one and electrode two apply uniform pressure to all wire cores. Combined with the current control of external welding equipment, the welding contact resistance between wire cores is reduced, the rate of false welds and spurious welds is reduced, and the overall mechanical strength of the welded wire cores is improved.

[0044] Solving the problem of difficult unloading and improving processing efficiency and equipment life: The unloading mechanism uses the slope of the pad to push the floating seat up and the tension spring to pull the floating seat back to its original position, realizing the automatic separation of the wire core and the electrode, shortening the unloading time and improving processing efficiency; at the same time, it avoids wire core deformation and electrode wear caused by manual prying, extends the service life of the electrode, and reduces equipment maintenance costs.

[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
