Assembly & Test Equipment

Semi-Automatic Assembly Line for MDPI

We would like to offer our customers, for phase 1-3, everything out of one hand! And at a relatively low cost compared to the fully automatic version!

The Concept

Our Assembly Modules consists of four workstations (named Module 1- 4), with intermittent manual transfer of parts and /or products between the parts sources, the workstations and any ancillary stations or units (e.g. coiling and blister insertion unit).

 

The material flow


The material flow is to be organized following the "Milk-run" concept, i.e., one worker checks the contents of the individual workstations on a regular base (e.g. every 20-30 minutes) and provides for refilling the parts supplies from bulk containers into workstation grasp boxes and for loading/unloading trays with pre-assemblies or finished assemblies or products, respectively.

The Assembly


The workstations are designed according to ergonomic principles and are equipped with partly mechanized fixtures. The fixture equipment is designed to provide for safe operation and error avoiding assembly according to the POKA YOKE principle.


Therefore e.g. the shape of the fixture and/or locating pins within the fixture allow for insertion and deposition of the correct parts to be mounted only in the correct position and orientation.

Module 1 - High Efficiency Manual Workstation for Pre-assembly of DPI Contracting Wheel Subassembly

 

The Manual Workstation is designed for an output of approx. 4-6 units per minute.

Module 4 - Semi Automatic Workstation for Final DPI Device Airflow Test

 

The Workstation is designed for an output of approx. 3 units per minute. 

 

The Workstation provides for semi-automatic test of the airflow properties of the assembled and blister filled devices.

 

The devices to be tested are supplied in manually transferred trays from the final assembly station. Devices are manually loaded into a device specific take-up cavitiy (test bed) and an airflow test (without API) is carried out by checking an empty blister pocket within the DPI device.

After loading and triggering the test sequence the device mouthpiece is automatically contacted via the appropriate adapter with a standard flow controller apparatus and it's auxililiary devices, such as flow meter and vacuum pump.

 

 

 

 

 

 

 

 

The the test result is signalled to the operator as "ok/not ok" by means of light signals on a mini-HMI.

 

Finished and checked DPI devices are manually unloaded from the test bed and are loaded into trays for manual transfer to secondary packaging stations
