Automating the ejection of electronic components for TDK Croatia

Parts coming from processing sit in a carrier grid and have to be removed. We built KOTRA, a machine that ejects the parts with a hydropneumatic press and handles the grid magazines on its own.

01 - Challenge

After processing, parts had to be removed from the grid by hand

Parts coming from processing at TDK Croatia in Kutina are arranged in a carrier grid and have to be taken out. The task was to build a machine that could do this on its own instead of manual ejection.

Since a press is used for ejection, most of the engineering focused on safety - presses belong to a special safety category of machinery.

02 - Solution

A hydropneumatic press with autonomous grid magazines

We built KOTRA, a machine that receives the grid and ejects the parts with a hydropneumatic press. Besides press safety, a particular focus was on autonomy - we added a magazine for the grids that receive the ejected parts and a separate magazine for empty grids.

The result is a machine that runs for long periods without an operator, with a defined and repeatable number of ejected parts on every grid.

Press safety category

Most of the engineering went into safety, because a hydropneumatic press belongs to a special safety category of machinery.

Magazine for ejected parts

An autonomous magazine receives the grid with the ejected parts, with no need for an operator to be present at all times.

Magazine for empty grids

A separate magazine automatically takes the empty grids after ejection, further extending the machine's autonomous operation.

03 - Result

A machine that runs without faults - and without service calls

0 service calls
the machine runs without faults and has needed no service calls
2 magazines
for ejected parts and for empty grids - autonomous operation
Defined count
of ejected parts per grid, with no manual counting
Press
hydropneumatic design according to its safety category
