Fuji has developed the new AIMEX II all-in-one placement machine which expands on the technology of its popular AIMEX platform by increasing flexibility and expandability.
The new machine is well suited for high-mix low-volume production and variable-mix variable-volume production. It supports small panels from 48 x 48 mm to very large panels up to 759 x 686 mm.
In order to support the large volume of part types required for high-mix production, up to 180 different part types in tape can be set on the machine. In addition, the supply units can be easily changed, with a wide variety of units available to supply parts from trays and sticks in addition to tape. Head types as well as the number of robots (up to four per machine) can be selected to match changes in the type and scale of production.
Auto Shape Generator at the machine is now offered as standard to reduce the time required to ramp up production from introducing a panel type during high-mix low-volume production. When using the NPI (New Production Introduction) support function and a vision processing error occurs at the machine, fast continuation of production is possible because vision processing data is automatically recreated based on the actual acquired image. This reduces the production startup work when products are changed.
AIMEX II can perform dual-lane independent production of different panels at the same time by using double conveyors. With this setup, while one lane is producing, changeover can be performed at the other lane. This means that the equivalent of two lines can be operated while only using a single line of machines.
A multi feeder unit (MFU) that can be used to exchange feeders as a group is used as the feeder supply unit. When the offline power supply unit (option) is used, feeders can be set up on the MFU offline and all of the feeders on the unit can be rewound automatically with the touch of a button. This makes external changeover work more efficient and faster.
Tray units used to supply parts in trays can be loaded at the front or back side of machines. Non-stop tray part supply is possible using the independent magazine configuration from Fuji. This makes it possible to reduce the amount of time the machine is stopped when tray parts run out during production.
Parts up to 38,1 mm in height can be handled on the AIMEX II with the odd-form part OF head. This allows the machine to place tall parts such as large relays and LAN connectors that are commonly used for automotive panels and motherboards, just by changing the parts supply unit.
Selecting to use V-Advance (feeder pallet shifted forward) while using V12 heads leads to shorter distances between the pickup and placement positions and improved throughput.
It is possible to build a line that can handle variable-mix variable-volume production by connecting an AIMEX IIS to increase the quantity of feeders that can be set and further expand the quantity of robots that can be used.

Editor's Choice Manufacturing / Production Technology, Hardware & Services
Dross formation is an inevitable consequence of wave soldering. It occurs when molten solder comes into contact with oxygen, forming metal oxides that float on the surface of the solder bath. Over time, this oxidation byproduct accumulates and must be removed to maintain solder quality and process consistency.
