Automatic Wire Cutting, Stripping & Terminal Crimping Machine for PCB Assembly

Every PCB assembly line that connects boards to power, signals or peripherals needs finished wire harnesses — cut to length, stripped, and terminated with the correct connector terminal. Done by hand, that work is slow, inconsistent, and a hidden source of quality escapes. Southern Machinery — the Shenzhen-based SMT/THT PCB assembly automation specialist founded in 2011, serving 237+ global customers — supplies the automatic wire cutting, stripping and terminal crimping machine (also called a winding displacement terminating machine) that finishes the job in one pass: feed cable, cut, strip, and crimp single- or double-end terminals automatically under industrial computer control.

What Is This Machine Used For?

Q: What is an automatic wire cutting, stripping and terminal crimping machine used for?

It is a full-automatic cable and wire-harness processing machine. It feeds cable, cuts it to the programmed length, strips the insulation, and crimps a terminal onto one or both ends — the complete wire preparation step that supplies connectors, screw terminals, and board-to-board wiring in PCB assembly. The feeding system, cutting and stripping system, mechanical hand clamping and transmitting system, twisting system, and terminal crimping system are integrated into one frame and coordinated by the computer control.

Q: What does "winding displacement terminating" mean in this machine's name?

Southern Machinery markets the equipment as a winding displacement terminating machine. The key point for a buyer is what the machine does: it positions the cable precisely with a Panasonic servo motor, ensures the conductivity of the cable and winding displacement, and forms the terminal connection with a flipping structure that can turn the cable upside down for double-end processing. This is the same "one machine does the whole harness" workflow that EMS and cable-assembly shops need.

Q: What does it do in an LED or EMS factory?

The same unit prepares the cable harnesses used to connect LED driver boards, lighting PCBs, power supplies and control boards. Southern Machinery's own demonstration videos show double-end winding terminal crimping for PCB assembly and cable terminal crimping for LED PCB assembly — the machine replaces the manual cutting, stripping, and crimping bench in the harness cell.

Capability and quality features (from the product page):

• Wide terminal range — handles cable terminals such as JC, PH, XH, EH, ZH, SCN, SM, VH, Dupont, etc.
• High precision — stepping motor control for cutting, branching and peeling length with accuracy up to 0.1 mm.
• Consistent crimping force — eccentric shaft mechanism for crimping gives balanced, consistent force for high yield.
• Accurate positioning — Panasonic servo motor controls cable location for reliable conductivity and winding displacement.
• Built-in error detection — detectors flag no wire, wire overload, wire deviation, low pressure, and missing stripping or crimping, with alarms.
• Easy operation — touch screen interface, simple parameter setup; one operator can maintain several machines with basic training.
• Industrial computer control — the integration of light, machine, air and magnetic systems is coordinated by the controller.

Typical Application Scenarios

• EMS / ODM harness cells — automatic cut, strip and crimp replaces the manual bench for high-mix cable production feeding PCB assembly lines.
• LED lighting manufacturing — cable termination for LED driver and lighting PCBs, where wiring connects boards to lamp sockets, power inputs and dimming controls.
• Power supply and home appliance assembly — internal wiring for power boards, ballasts, induction cookers, electric kettles and similar products.
• Automotive electronics — connector harnesses for vehicle power supplies, audio and control modules (application parameters confirmed with Southern Machinery).
• Industrial control — pre-terminated wires for PLC, inverter and instrumentation boards.

How It Integrates into a Complete PCB Assembly Line

The crimping machine sits in the material-preparation stage of the SMT/THT line, upstream of final assembly. While the SMT line runs solder paste printing, pick-and-place and reflow, and the THT side runs radial/axial/odd-form insertion followed by wave soldering, the harness cell prepares terminated cables in parallel. Finished harnesses are kitted to the board assembly or final-assembly stations, where operators (or automated insertion equipment) connect them to PCB connectors. Because the machine is a standalone, self-contained unit, it slots into an existing factory layout without conveyor integration — the only requirements are a 220 V single-phase supply and 0.4–0.6 MPa filtered compressed air.

Key Selection Parameters

Before ordering, confirm these parameters with Southern Machinery for your specific cables:

• Wire and cable range — wire diameter (verified machine: 0.8–3.0 mm), max. cable width (verified: 35 mm), cable types (e.g., 2468 and similar).
• Terminal family — JC, PH, XH, EH, ZH, SCN, SM, VH, Dupont, or custom terminals.
• Crimping configuration — single-end or double-end crimping, interleaving crimping, cable flipping.
• Length and strip requirements — cable length (> 75 mm) and peel length (2–10 mm) within range.
• Throughput target — verified machine rating is 18,000 PCS/H on a 10-pin cable; confirm against your cable mix.
• Utilities — 220 V 50 Hz, 600 W; 0.4–0.6 MPa filtered, dried air.
• Floor space — 1.65 m × 0.75 m footprint (300 kg weight).

ROI, Quality & Throughput Perspective

Manual cutting, stripping and crimping is one of the most labor-intensive jobs in PCB assembly. A single automatic machine rated at 18,000 PCS/H on a 10-pin cable replaces that bench and runs 24 hours with consistent results. Quality improves through three mechanisms: consistent eccentric-shaft crimping force (fewer loose or over-crimped terminals), 0.1 mm stepping-motor precision on cut and strip length, and built-in detectors that alarm on no-wire, wire deviation, low pressure, or missing stripping/crimping — defects that would otherwise travel to the line and cause field failures. The small footprint (under 1.5 m²) and touch-screen programming mean the machine pays back through direct labor reduction and rework savings, and the same operator can supervise several units.

FAQ
