Essemtec combines a standard 2-D SMD pick-and-place of the Paraquda series with a 6-axes robot. The robot positions the substrate holder so that the placement level is always horizontal. Because of this concept, the 3-D assembly machine Hydra is able to use the same component feeders as a normal SMD placement machine, the same spare parts, the same vision system and even the same pickup tools. The Paraquda’s software and control system is simply expanded by a robot controller.
The Hydra can dispense glue in nearly any position and assemble SMD components accurately. The 4-axes pick-and-place head can place up to 2,500 cph in 3-D mode and up to 7,000 cph in 2-D mode.
The placement area is specified at 300 x 160 mm. The placement axes features a vertical travel range of 50 mm and, therefore, can place components into deep cavities. The component range spans from 01005 up to 20 x 20 mm with a maximum height of 18 mm. The machine features an inline conveyor system and quick changeover, making it capable of series production as well as small series and sample
