Attention! Sensitive technology – Precise separation and safe transport of PCB


Precise separation of PCB

In terms of thickness, PCB range in millimeters. Separation means significant mechanical stress. Resistors, microcontrollers and condensers, assembled close to the milled groove on little space, might be damaged. cab MAESTRO devices have been developed for low-stress PCB separation.

With a MAESTRO 4S, a milled groove can be traversed by the circular blade several times ? special blade settings provided, even PCBs made of aluminum. By traversing twice (with the blade distance readjusted using a motor), stress is already further reduced. High-quality cut-offs improve the quality of PCB significantly. Separation lengths up to 600 mm can be set continuous. On a MAESTRO 5L, a maximum of 15 PCB can be arranged next to each other, to be separated simultaneously. Separated PCB are deposited to an integral conveyor belt. The MAESTRO 6 has been designed for applications using extra-long materials up to 1,500 mm in length.

Safe transport of PCB

The latest assembly plants must adapt to individual needs several times a day. To transport PCB of different sizes, magazines must be adjusted consecutively. Depending from a magazine, widths are set using screw clamping or a toothed belt, the latter been adjusted by hand or a motor.

cab series 800 PCB magazines provide a coupling. When inserting a magazine onto the loader of an assembly plant, the flange on the servo motor of the loader connects to the coupling. The flexible side wall of the magazine moves on threaded spindles with uniform precision to a reference spot. Parallelism is provided. Then the magazine automatically adjusts to the width of the flat modules specified by the plant control. There is no need for providing pre-adjusted magazines on stock. Human errors are avoided, while process quality increases.

About 350,000 flat modules are manufactured every month at the SEW Eurodrive electronics plant in Bruchsal, South Germany. These are fed from cab magazines to assembly plants each day. At the end of a plant, mobile transport systems pick up the magazines and all the data relevant for processes. Flat modules assembled on one side are transferred to the next production step. In the case of PCB assembled on top and bottom sides, the magazines are again picked up by a mobile assistant, to find their way back to the beginning of a plant. These PCB are turned to their opposite site and refed to a plant. Assembly starts again.
