 The TWS Automation Quadra is well known for its flexibility, ease of use and low cost of ownership.
The TWS quality/price ratio has revolutionised the concept of surface mount assembly, which was previously considered to be only suitable for large volume manufacturers with large assets.
Unbeatable for small and medium volume manufacturing, the TWS Quadra eliminates the need to sub contract work, thus allowing users to control their quality in-house.
These characteristics have led many customers to expand their production by installing a second and third Quadra rather than looking for a larger machine with higher throughput.
The most important features are:
Cost effective: the machine, having laser centring, has been designed to considerably reduce the capital cost compared to other similar machines currently available. The low cost of the feeders enables users to work with a large feeder inventory to speed up the assembly operation.
High life time: the simple mechanical design uses no delicate mechanisms, and the Quadra has been tested to have a long and reliable life span. The new placement head equipped with laser centring ensures high durability, and high speed of placement.
Easy to manage: the machine’s software uses very simple menus, enabling the operator to gain a high level of confidence in a short time. The machine comes with a detailed user manual and maintenance guide, and with a practical guide for assembly that includes all stages of production, such as SMD component analysis, solder paste, adhesives, screen printing, soldering, board inspection and verification, repairing and cleaning.
Easy to maintain: all parts of the machine are easy to access and maintain. Maintenance can be carried out by the Operator, who can call our assistance if needed.
The machine is driven by a standard PC. Spare parts are low in cost and always available from stock with a fast turnaround. An integrated system provides diagnostics for testing and measuring power absorption of the boards inside the machine. The integral CPU also controls the machine I/O’s such as vacuum, electro-magnets, laser centring, axis movement and status of the limit switches.
Quick feeder changeover: the feeders can handle various tapes or stick sizes.
New feeders can be prepared off-line in order to reduce downtime for program changeovers.
High numbers of feeders: The unit can handle all the main types of components and accommodates up to 120 feeders in total, in tape from 8 mm to 44 mm width with 7’’, 13” or 15’’ reel diameter.
A catalogue is available for stick components. IC lanes for components not listed in the catalogue may be prepared in a short time.
Programming modalities: There are three ways of programming:
Teaching through camera, data loading via CAD file, data entry via keyboard and prepared by an off-line programming digitiser.
Automatic fiducial recognition: At the beginning of every assembly cycle, the camera automatically moves to the memorised reference points, searches for their exact position and adjusts the placement positions, for better precision.
Dispensing of adhesives and solder paste: The optional dispenser enables easy and rapid dispensing of adhesive and solder paste. The dispenser is simple to set up and achieves over 4000 dots per hour.
Smart feeders: With its feeder database the Quadra Laser provides fast set-up. There is no need to re-enter the feeder data, since a new electronic system detect automatically feeders mounted on the machine, loading data of the components already present in that feeder. It doesn’t matter if you change position of the feeder: machine will recognize it. Each time a component is picked-up, its quantity is decremented. After the feeder data has been recorded for the first time, every subsequent time a group of feeder banks is changed, you can run the function that automatically detects the feeders and their positions on the machine.
Network connection: Connecting a Quadra to a local network (LAN) allows the user to easily and automatically make a back-up copy of the mounting program onto an external PC. The program and configuration files can be transferred from one machine to another without using external devices such as floppy disks.
Use of the LAN network, also allows the feeder database to be used in conjunction with smart feeders and the information can be shared by all the machines, reducing set-up time. The feeder database is updated with every change made to the feeder configuration.
Centring by vision system: An additional camera looking upward is available as an option to accurately centre components. The camera is located at a fixed position on the work area and provides more accurate centring of BGAs, fine-pitch ICs, large components and similar.
