Jonas in action

Automation before the automation age!?

What you see below are assembly rings - also called "Renfer rings". It allows Jonas to have a high degree of process stability during his assembly work. Think of it like Jonas automating himself... without having to run expensive numeric controlled assembly line equipment.

Simple..., proven for many centuries and does the job it is expected to do.

One hand operates the ring, the other sets the part, the eyes are focused.

Parts trays help to keep overview about the parts consumption. You can get easily disrupted from some person walking into the workshop or a phone ringing and then... you might forget a screw or some small part. Assembly is a real challenge as it involves humans and their constant focus.

Quality comes from routine... this is why Jonas builds tools for every single step

The assembly rings help the assembler to keep distances short and enable him execute his routines in a certain rhythm. But they also perfectly serve as interim storage devices and dust protection during down times between the different assembly stations.

      Hi Mitch,
      This semi-automatic machine allows to apply a defined amount of oil at the cavity of the ruby. Once we have a bit more volume this is better done by fully CNC controlled oiling machine.

      Yes there is a lot of hand labor to do. Even in highly automated mechanical movement assembly lines, many humans are involved. The automation is mainly in the sorting, feeding and transportation between the different assembly stations as well as in the QC processes. And there are a lot of QC checks needed considering that there are more than 150 parts involved where things can go wrong;-)

      Pick and place action when completing the movement is mainly done by humans, because some of those sub-assemblies are very difficult to handle by a machine.

      Awesome stuff and lots of room for improvement in future.

      Looks like the movements are coming along quite well! I am curious what the tool in the picture above the caption "Quality comes from routine... this is why Jonas builds tools for every single step" is I cannot recognize its function.

      I know one of your end goals is mass production and automating as much of the process as possible, with this something of a proof of concept (but also I assume far more manual labor than eventually planned?). Thanks for the insights and pictures!

      Looking good Roger!
