SFT830 Fuse Terminal Assembly Machine by Southern Machinery

The SFT830 fuse terminal assembly machine from Southern Machinery automates dual brass-clip insertion into blade fuse sockets. According to the source product page, it runs at approximately 2,000 pcs/hour with dual vibratory bowls and CCD vision orientation checking, replacing 4-5 manual operators. It is designed for automotive and PCB blade fuse holders in standard ATC and mini formats.

Why does manual fuse socket assembly keep capping your output?

Hand-pressing two brass clips into a plastic socket looks like the cheapest step on the shop floor. It rarely is. The source page benchmarks manual assembly at 350-450 pcs/h, versus approximately 2,000 pcs/h for the SFT830 under continuous feeding.

The hidden cost is not just speed. A reversed clip can slip past a tired eye and later fail as an intermittent contact. Your line looks busy, yet output, yield and shift staffing all depend on a few people repeating the same motion thousands of times.

What does a repeatable automation checklist look like?

Before looking at any machine, run the same four checks on your own fuse holder:

1. Part geometry: Do you have 2D/3D CAD for the socket and the clip? The clip needs asymmetric features that a camera can read.
2. Format mix: Which formats do you run: standard ATC/ATO (5 mm), mini blade, maxi/high-current, or a custom through-board socket?
3. Volume band: Is your monthly volume closer to 100,000-300,000, 300,000-1,000,000, or above 1,000,000 pcs/month?
4. Changeover rhythm: How often do you switch formats, and who performs the changeover?

If you can answer these questions, you can brief an automation supplier in a single message instead of five.

How does the SFT830 turn that checklist into a working cell?

The SFT830 is a custom, non-standard automation system built around a four-stage sequence:

Dual vibratory bowl sorting

Two bowls orient loose brass terminal clips and plastic socket bodies into single-file lines so bulk parts feed continuously.

Track and CCD vision check

Linear tracks carry parts past a CCD gate. The vision algorithm checks asymmetric clip features such as spring detents and solder-tail notches, and a pneumatic diverter isolates any reversed part.

Pick and dual insertion

Pneumatic pick stations 1 and 2 transfer parts to insertion stations 1 and 2, which drive two terminals into the socket block simultaneously.

Auto ejection and count

Finished holders exit through a chute into a bin, while the PLC touchscreen HMI displays production counts and yield data.

What are the key selection parameters?

| Parameter | Value from source |

|---|---|

| Throughput | Approx. 2,000 pcs/hour, dual synchronized insertion channels |

| Power | Single phase 110V / 220V AC, 50/60 Hz |

| Air pressure | 0.4-0.8 MPa, clean dry air |

| Dimensions (L x W x H) | Approx. 1400 x 1000 x 1600 mm |

| Net weight | Approx. 350 kg |

| Target components | Blade fuse sockets plus dual 0.4-0.8 mm brass clips |

| Core hardware | AirTAC cylinders, valves and fittings; HIWIN linear guides; DC PLC and HMI |

Tooling for standard and mini fuses is available as quick-change sets (interchangeable bowl tracks, feed guides and insertion punches). The source quotes a changeover time of approximately 15-20 minutes. Specifications remain subject to final technical confirmation for your part.

How should you estimate payback?

Use a simple formula with your own numbers:

Annual labor savings = operators replaced x monthly wage x 12 x shifts factor

The source calculator shows an example with 4 operators per shift, a $1,500 monthly wage and 2 shifts, giving about $144,000 per year and a payback of about 2.8 months. Treat this as an example only: the result depends on configuration, local wages, tooling and the final quotation, and it is not a guarantee. The machine price is not specified in the source; contact Southern Machinery to confirm.

Where does it fit in a wider PCB assembly operation?

Fuse sockets and similar terminal parts often feed THT and odd-form workflows. Southern Machinery, founded in Shenzhen in 2011 and serving 237+ global customers, supplies SMT and THT automation.

FAQ

What is the lead time for a customized SFT830?

The source states that standard build and factory acceptance testing takes approximately 25-35 working days, plus 7-10 days for custom tooling on non-standard clip geometries.

How does the vision system prevent reverse insertion?

A CCD camera over the linear feeding rail verifies asymmetric clip features in real time, and a pneumatic air diverter removes reversed parts.

Can one machine handle standard ATC and mini blade fuses?

Yes, with quick-change tooling sets; changeover takes approximately 15-20 minutes according to the source.

What warranty and support come with it?

The source lists a 12-month warranty, lifetime remote engineering diagnostics, international express dispatch of spare parts, and on-site commissioning and training on request.

What should you do next?

Send your fuse holder 2D/3D CAD drawings and clip specifications. The source says Shenzhen engineers prepare a custom proposal, cycle-time simulation and quotation within 24 hours. Request a quote or contact us.
