The successor to the KE-2050, Juki’s new KE-2070 is a sixth generation high-speed modular chip shooter.
Built upon the one-piece SuperCast single casting base that includes the Y beams, the machine is designed with speed, accuracy and reliability in mind. Combined with the new LNC-60 high-resolution 360° component laser centring system and an improved magna-scale resolution down to 1 μm, the KE-2070 is 25% more accurate than previous models and is capable of placing components down to 01005 size.
A new head design featuring six nozzles reduces the number of required nozzle changes, improving the rated IPC-9850 speed to 16 000 CPH. This new design also increases the maximum component size that can be placed to 33,5 x 33,5 mm. The high-resolution 360° component laser centring system ensures that the correct nozzle is in use, and component presence monitoring monitors the presence of the part from pick to place. These features are built into the head, making a side trip to a camera unnecessary.
A new multinozzle vision centring system (MNVC) is available for use with the KE-2070. This system gives the machine the ability to inspect leaded or BGA parts via an upward looking camera for placement.
The KE-2070 introduces new stepper motors in the conveyor system that allow for enhanced speed control for the entire conveyor. The motion control communications have been upgraded from serial communications to fibre-optic communications, resulting in fewer and smaller cables with increased speed. A USB port is now available as a means of communication to and from the machine.
The KE-2070 has been designed to be compatible with existing Juki feeders, trolleys and software.
