SIASUN Automatic Nail-Blowing And Tightening

On many engine lines, the slowest part of fastening is not the tightening itself but the moment before it: a hand reaching into a tray, a bolt pre-started by the fingers, a tool lifted back into position. The SIASUN Automatic Nail-Blowing And Tightening solution removes that moment. Bolts travel by air to the tip of the tightening gun, and the gun, guided by a collaborative arm, drives them into the side of the engine without anyone setting them in advance. The result is fastening that depends on the process rather than on whoever is working that shift.

Robots Europa, based in Dublin, supplies the SIASUN Automatic Nail-Blowing And Tightening to manufacturers across the European Union and the DACH region. Robots Europa prepares each quotation against the customer's assembly task, arranges delivery and customs, and provides support for the installation from first enquiry onwards.

Background

SIASUN and its automotive lineage

SIASUN is the largest AGV supplier in China and has over 20 years' experience in automotive body chassis marriage, the stage at which the body and the chassis of a vehicle are joined on the line. That heritage matters for a fastening solution: it comes from a manufacturer whose work has long centred on automotive assembly, where many fasteners must be placed reliably within a fixed cycle. The nail-blowing and tightening solution applies that experience to a narrower task, the tightening of bolts on the engine itself. Further equipment from the same manufacturer can be found in the SIASUN range.

Blow-feeding meets the collaborative arm

The solution combines two ideas. The first is automatic bolt delivery: bolts are placed in a feeder, vibrating discs screen and arrange them neatly in turn, and the nail-blowing equipment blows each bolt through a pipe to the end of the tightening gun. The tightening gun's batch head then ejects the bolt and tightens it on the side of the engine. The second idea is the arm that carries the gun. In combination with the multi-collaborator arm, tightening can be carried out at multiple angles, in multiple positions and in confined spaces, which is where manual tools tend to struggle. Because the robot can be deployed freely according to the space available on site, the cell can be fitted to an existing layout while assembly accuracy and the line's work beat are maintained.

Technical Specifications

Specifications as published by the manufacturer; confirmed against the datasheet at quotation. The manufacturer has not published the dimensions, the weight, the tightening torque, the bolt size range, the feed rate, the power requirements, the robot model used, the payload, the communication interfaces or the package contents; these are confirmed at quotation.

What makes automatic nail blowing different from manual bolt feeding?

In manual fastening, each bolt passes through an operator's hand at least once: it is picked, oriented, often started by a few turns, and only then tightened with the tool. Each of those steps adds time and variation. With the SIASUN Automatic Nail-Blowing And Tightening, the vibrating discs present the bolts in order and the nail-blowing equipment sends them straight to the gun, so the advance bolting step disappears entirely. For small bolts in particular, this enables fast tightening, because the tool no longer waits for a fastener to be placed.

The second difference lies in consistency. Automatic tightening guns are used in this application precisely so that the tightening strength meets the process requirements and a satisfactory tightening rate is achieved. When the same gun, carried by the same arm, tightens every bolt in the same way, quality becomes a property of the cell rather than of the individual operator. The solution helps companies keep product quality controllable and improve their level of automation.

How does the collaborative arm change the tightening cell?

Engine sides are rarely flat and open. Bolts sit at different angles, at different heights and sometimes in recesses that leave little room for a tool and a hand together. Pairing the tightening gun with the multi-collaborator arm allows multi-angle, multi-position and small-space tightening, so a single cell can reach fastening points that would otherwise need a worker to reposition repeatedly.

The collaborative nature of the arm also shapes how the cell sits on the shop floor. The safety of the collaborative arm helps companies reduce production accidents. And because the robot can be deployed freely according to the site space, planners can place it where the line allows rather than rebuilding the line around it, while assembly accuracy and the work beat are maintained.

Who is the SIASUN Automatic Nail-Blowing And Tightening for?

The clearest fit is the engine assembly plant that tightens many small bolts on the side of the engine and wants that operation to run without manual pre-bolting. Manufacturers running round-the-clock production are a second group: the solution can replace workers on three production shifts, which helps companies save on labour costs, address recruitment difficulties and keep production stable.

Production and quality managers who must show that tightening strength meets process requirements will find the case for automatic tightening guns straightforward. Health and safety teams looking to reduce accident risk at repetitive fastening stations are another audience, given the collaborative arm. Finally, system integrators and plant engineers working in tight or irregular layouts will value the free deployment of the robot according to site space.

Buyers whose need lies further along the vehicle line, rather than at the engine, may wish to look at the SIASUN Interior & Finishing Line Assisted Assembly Mobile Robot, or browse the wider SIASUN category; Robots Europa can advise on which solution matches the task.

Pricing and Availability

The SIASUN Automatic Nail-Blowing And Tightening is configured around a specific engine, fastening pattern and line layout, so Robots Europa supplies it by quotation rather than at a fixed list price. To prepare a quotation, it helps to describe the bolts involved, the fastening positions on the engine, the space available and the cycle time the line must hold. Delivery, customs and support are arranged with the quotation. The way to begin is the quotation request available on this page.

Frequently Asked Questions

How do the bolts reach the tightening gun?

Bolts are placed in a feeder, where vibrating discs screen and arrange them in turn. The nail-blowing equipment then blows each bolt through a pipe to the end of the tightening gun, whose batch head ejects and tightens it.

Do operators still need to pre-start the bolts?

No. Automatic nail blowing for small bolts eliminates the need for advance bolting, which is what enables fast tightening.

Can it tighten bolts in awkward positions?

Yes. In combination with the multi-collaborator arm, the solution supports multi-angle, multi-position and small-space tightening.

Does the cell need a dedicated layout?

No. The robot can be deployed freely according to the site space, while assembly accuracy and the work beat are maintained.

What experience does SIASUN bring to automotive assembly?

SIASUN is the largest AGV supplier in China and has over 20 years' experience in automotive body chassis marriage.

How does it affect safety and staffing?

Summary

The SIASUN Automatic Nail-Blowing And Tightening addresses the moment before the tightening: the bolt that once had to be picked, oriented and started by hand now arrives by air at the gun, ready to be driven. Vibrating discs arrange the bolts, the nail-blowing equipment delivers them, and a multi-collaborator arm takes the gun to angles and spaces that manual tools find awkward. Behind it stands a manufacturer with over 20 years in automotive body chassis marriage, and in front of it a set of practical gains: no advance bolting, coverage of three production shifts, a safer collaborative cell and tightening that meets process requirements. Robots Europa quotes, delivers and supports the solution for manufacturers in the EU and the DACH region.
