Abstract

Due to the mechanical decoupling of protection device and weighing device, it is possible for the first time to measure the blade weight during the coating process.

First claim

1 . An apparatus for weighing and protecting a component during coating of the component, comprising:
a weighing module configured for measuring the component; a protective sleeve or covering located and configured for protecting at least a part of the component from the coating during coating; and the weighing module is mechanically decoupled from the protective sleeve.

2 . The apparatus as claimed in claim 1 , further comprising:
the protective sleeve comprises at least one shielding plate starting at a selected height of the component to be coated, wherein the shielding plate is located and configured to shield a bottom part of the component below the selected height against coatings.

3 . The apparatus as claimed in claim 2 , further comprising:
the protective sleeve includes a flexible sleeve arranged as part of the protective sleeve and the flexible sleeve extends between the shielding plate and a base plate of the apparatus, the protective sleeve runs at an angle which differs from 0 ° , with respect to the shielding plate, and the protective sleeve is exposed to the coating material in order to achieve a dust, pressure and temperature barrier toward the part of the component in the protective sleeve.

4 . The apparatus as claimed in claim 2 , further comprising:
an actuator configured to adapt the shielding plate in its height with respect to the component to be coated.

5 . The apparatus as claimed in claim 1 , further comprising a clamping apparatus located and configured for clamping to and supporting the component with respect to the weighing module;
wherein the clamping apparatus is mechanically decoupled from a protective sleeve and has a modular form.

6 . The apparatus as claimed in claim 5 , wherein the clamping apparatus is arranged on the weighing module.

7 . The apparatus as claimed in claim 5 , wherein the clamping apparatus is adaptable to the weighing of various components.

8 . A method for coating a component using an apparatus as claimed in claim 5 , and the method comprising measuring the layer weight without removing the component from the clamping apparatus during the coating.

9 . The method as claimed in claim 8 , further comprising during the coating, blowing air in a direction of a coating material from a gap between a shielding plate of a protective sleeve and the component to be coated.

10 . The method as claimed in claim 8 , further comprising measuring a layer weight after each coating layer or after a selected number of coating layers, and comparing the measured weight with a nominal value.

11 . The method as claimed in claim 8 , further comprising deactivating the weighing module during the coating and activating the weighing module when coating is not being performed.

12 . The method as claimed in claim 10 , wherein the coating parameters are adapted to a coating nozzle.

13 . The apparatus as claimed in claim 2 , further comprising:
the protective sleeve includes a flexible sleeve arranged as part of the protective sleeve and the flexible sleeve extends between the shielding plate and a base plate of the apparatus, the protective sleeve runs at an angle which differs from 90 ° , with respect to the shielding plate, and the protective sleeve is exposed to the coating material in order to achieve a dust, pressure and temperature barrier toward the part of the component in the protective sleeve.
