Drying and curing of end devices

Equipment for backend assembly

Wind power renewable energy is playing an increasingly important role in the energy mix,

electric drives have to deliver more and more power while consuming less energy. Rapid

charging stations for hybrid and all-electric drives are in increasing demand and powerful

battery storage devices are designed to help stabilise the power grid. They all have one

thing in common – they all have control electronics and electronic housing assemblies

inside them whose reliability has to be guaranteed at all times.

These highly complex assemblies use several manufacturing techniques, which are all there

to ensure the reliability of the assembly. Depending on the application and requirements, the

modules are painted to protect them from corrosion and environmental influences or have

to be rmly integrated into the housing by means of encapsulation or adhesive technology.

The drying and curing of different materials is an essential step of the process.

Rehm Thermal Systems offers innovative drying and curing processes for this eld of ap-

plication that meet any requirement. The new Pramo drying system guarantees best drying

and curing results thanks to reliable looped band transport. The flexible carrier receptors

are interchangeable, which means various assemblies – also special forms –can be guided

safely and reliably through the plant.

Technical Details

The Pramo at a glance

The assemblies on product carriers are transported through

the system in the Pramo continuous dryer with “shuttles” –

passing through several zones in which they are heated up to

the appropriate temperature and then maintained at the set

temperature for the drying / hardening process. Cycle time

depends on the time the assemblies need to harden the mate-

rials within the drying system according to specications.

1. Loading | Unloading

A robot / handling system loads and unloads

the components into the product carriers.

Manual loading and unloading can be an

alternative.

4. Measuring nacelle

The gondolas / carrier boats are equipped with

a clamping unit for automatic loading with a

robot. A measuring cable with prepared parts

and memory meter is can be easily used via a

quick-action

xation.

3. Cooling

The assemblies for downstream processes

are cooled in the cooling section. This allows

the assemblies to be subsequently processed

immediately. Each segment has cooled air

blown onto the carrier with the assembly. The

waste heat is transferred from the internal to

the external water circuit via a heat exchanger

and thus removed from the production room in

an energy-saving way. Alternatively there is a

residual management system with 2 cooler/lter

units for cold condensation available instead

of the heat exchanger. The lter can be easily

cleaned in an ultrasonic bath for maintenance

purposes. The return line can alternatively be run

as an additional heating zone when the parts are

unloaded when warm (warm function test).

2. Looped transport

The assembly is transported through the

machine on a circular product carrier transport.

This cycle time is adjustable. The transport

is carried out in loops in order to achieve the

longest possible throughput times and process

a high number of units. This reduces the sur-

face area as well as the height of the system.

Depending on the number of product carriers,

the Pramos is available as a 2-, 3 -, or 4-looped

transport.

5. Software

The system is controlled by software via a

touchscreen user interface. All relevant process

parameters such as throughput time and

temperature are documented via a barcode on

the product carrier nacelle and, if necessary,

transferred to an MES system. SMEMA interfa-

ces provide for the integration of the system into

any production line.
