Automated Assembly Solutions for Single-End Wire Welding and Assembly Line

Project scope

We designed an automated welding and assembly line for electronics sensor single-end wire products. The line links wire cutting and board loading, sleeve assembly and inspection, single-end welding, CCD inspection, tube pushing, heat forming, discharge, bending, shell pressing and collection. That makes the scope an automated assembly solutions application for single-end wire cutting, sleeve assembly, welding, ccd inspection and heat forming.

The confirmed equipment target is 600 to 800 PCS/H with three operators. The utility requirements are 0.5 to 0.7 MPa compressed air and AC220V power. The control architecture is HMI plus PLC.

Coordinating wire, sleeve and welding processes

This line has to keep small wire products aligned across several mechanical operations. Wire cutting and board loading define the initial pitch, sleeve feeding adds another component stream, and welding has to occur after the parts are positioned repeatably.

Inspection before downstream forming

The process includes front-side and back-side visual inspection. That inspection needs to happen before tube pushing, heat forming and final pressing, because defects or missing parts should be identified before more value is added downstream.

Changeover impact

The technical notes state that changing the assembled product requires replacing all fixtures and adjusting related components. Incoming material dimensions must stay within the corresponding tolerance range, and the final equipment size is subject to the refined 3D design and actual build.

Wire boarding and sleeve assembly

The front end uses a single-wire cutting and board-loading section with a wire-feeding rack, wire straightening, board transfer, tape application and visual inspection. The sleeve section uses sleeve feeding, sleeve transfer tooling and a sleeve mold that handles two sleeves per cycle.

Welding and visual inspection

After sleeve handling, the line moves into the single-end welding head section. A vibratory bowl feeding group supplies the small welding-head components, while the welding module positions and joins the component to the wire assembly. The CCD station checks the front and back sides before the product advances to the forming operations.

Tube pushing, heat forming and final handling

The downstream section converts the welded assembly with tube pushing and heat-shrink forming. The final handling section discharges the product, performs bending and shell pressing, and then collects the completed parts.

Proposed operating result

The line concept turns a multi-step single-end wire process into one connected automation route. It reduces manual transfer between cutting, sleeve handling, welding, CCD inspection, heat forming and final pressing, while keeping the confirmed operator plan at three people.

Engineering value

By placing CCD inspection before the downstream forming and pressing operations, the design gives the production team a clearer control point before additional process steps are applied. The confirmed capacity, utility and operator values also make the concept concrete enough for mechanical detailing, fixture design and final layout sizing.
