Continuous-Flex Cable & Cable Management for Robot-Handling System

cable carrier multi axis

In the new circuit board handling system, a six-axis robot replaces the hitherto used linear systems. A triflex® R multi-axis cable carrier supplies the robot's gripper.

 
Multi-axis cable carriers in clean room environment

One electronics production company uses a new technology to handle circuit boards: a six-axis robot using triflex® R cable carriers from igus®, which supply the robot's gripper.

The manufacturer is a specialist in designing and manufacturing plants for producing photovoltaics and circuit boards. This includes etching, laminating, removing resin, metallizing, laser cutting, measuring and testing, or conveying circuit boards, photovoltaic elements or displays.

Increasing processing speeds and, more importantly, customer demand for greater flexibility were the main reasons behind developing a completely new generation of handling systems using six-axis robots. Now cycle times of less than seven seconds are involved when loading and unloading circuit boards from boxes.

Loading and unloading systems for circuit boards

Loading and unloading systems separate circuit boards and then conduct them via a conveyor belt to a processing station.

The plants possess two parallel collection areas, so the robot can extract the circuit boards from the box and place them on a conveyor plate without pausing. When a box is completely unloaded, it begins to unload the circuit boards from the second, while the empty box can be exchanged for a full one on the first supply line.

The handling system’s gripper moves multi-dimensionally using triflex® R cable carriers from igus®.

The robot takes the circuit boards from one stack provided on one of the two supply lines and deposits them on a conveyor belt.

 
Loading and unloading without breakages

The facility is completely enclosed, which is important to preserve a clean environment. For space-saving reasons, the robot is essentially wedged into the machine housing, though it can move freely between the three handling areas. An interesting aspect of the plant is the gripper, which automatically identifies the size of the individual circuit board. The mounting plate with the vacuum grippers is made of low-weight carbon fibers, so that a compact 35-lb robot can be used and loads up to 15 lbs moved.

The robot’s cable management system didn't have enough space for enough cables to also supply the gripper mechanism. In the search for a suitable cable management system, the designers came across triflex® R.

Clean room technology and a material with high wear resistance

The triflex® R cable carrier is also made from an extremely wear-resistant material, which means it’s ideally suited to the clean room environment.

igus® also assembles patch plugs and mounting plates and supplies them ready for installation.
