Know-how and innovation for 30 years
With thirty years of skill, expertise and innovation, the neyret group is now renowned and respected around the world.
Our group masters even the most complex assembly and automation operations, giving us a solid base on which we can capitalise and stand out from our competitors :
- reliable, high-performance technology based on mechanical, high-precision cam systems,
- everything is handled in-house, from design and manufacture to machining, assembly and validation of assembly machines (continuous or indexed motion). We even provide training for all of our equipment,
- the capacity to anticipate how the market will develop over the medium and long term by selecting the right technology and innovations for tomorrow’s machines.
The product to be assembled may be complex and the required production rates may be high, but the neyret group will always offer our clients a full range of all the technologies they need.
Indexed motion systems
This technology (indexed motion machines) is particularly well-suited for the integration of processes which need the component to remain stationary (for riveting, machining, labelling, etc.). Societe Guy Neyret indexed motion machines (cam-driven machines) are robust and reliable. They can adapt to any area of activity and any type of component geometry, from the simplest to the most complex. These assembly machines use fully synchronised cam technology, and are a wonderfully efficient solution. Using a single motor, they can power every one of the machine’s movements, from the rotating ring right up to the various peripheral items and components. The advantage of this ring-based system is highly increased stability for the item to be assembled. With high-precision machining and “tight” machine assembly, you can assemble your items with great precision and implement a number of special processes (welding, gluing, folding, screwing, etc.), a wide variety of tests (vision, tightness, size, torque measurements, etc.), and even print information directly onto the item being assembled (laser marking without vibrations, etc.).
Continuous motion systems
This type of technology is used to produce high volumes of a specific product. These production runs can reach several tens or hundreds of millions of items per year. LAGNIEL SAS’ continuous motion machines offer high-speed automatic production systems (between 150 and 1,200 items per minute). Highly specialised, this technology is mainly used (and often required) for circular and other products. With this type of continuous motion machine, you can complete screwing, gluing, ultrasonic welding, lubrication processes, and many more.
The robotic solutions we offer are designed for several different uses :
- small, delicate components which require high levels of quality and precision,
- small and medium-sized series, from tens to several thousand components,
- multi-component, multi-reference, fixed or adaptable series,
- and for any sector: micro-mechanics, connections, electronics, medical, automobile and more.
There are several different types of assembly robots, offering a whole range of different solutions :
- Robots integrated into the flow of an assembly machine
- Independent master robots for automatic or semi-automatic cells
- Transfer robots, sending items to a sub-system (to a stamping press or other system)
- Tracking robots for random “Pick and Place” component assembly
Within the group, the Societe Guy Neyret Company has also developed a non-standard assembly robot: the E-manip. This increases the movement options available to “Pick and Place” manipulators.
Checks and tests
We can propose and develop any type of checking system on our machines: tightness (leak, pressure, low pressure, volume), presence, size, stacking, scans, X-ray, vision, strength, torque and flow. For leak tests, we can offer two solutions: either integrating systems provided by a specialist, or using “homemade” modular applications to conduct testing, measuring and checking, using dedicated test benches. Acquisition is most often analogue, with data acquisition and visualisation, either by the operator-machine interface or via a PC.
The group has had an industrial vision department for thirty years. Thanks to our extensive experience in component handling for high-speed assembly, we can meet any demand – even in the pre-project phase. Vision ensures that 100% of the items and assembly procedures are checked. The aim here is zero defects. This is used for products which are classified as human-safety items (automotive, aviation, space, etc.), as they provide a redundancy check on top of any other procedure. This is now mandatory for machines in the medical or pharmaceutical sector.
We also use it for the following points :
- Dimension checks (functional size measurements, component measurements, etc.)
- Vision and integrity (missing material, deformation…)
- Presence (components, grease, oil, labelling…)
- Compliance (compared to references…)
- Character recognition
- Process discrepancies (injection, cutting, stamping…)
- Component sorting
As fully certified agents and a Cognex Training Centre, we are able to propose several different levels of training both in-house and in the clients’ premises. These run from a basic understanding of the installed systems to the creation of new references.
