Abstract

An installation is provided for cleaning a plate used in an additive manufacturing process performed using a powder. The installation includes an entry lock, an exit lock, a dry cleaner, a wet cleaner, and a conveyor system. The entry lock is structured to accept into the installation a plate that is to be cleaned. The exit lock is structured to allow the plate to be extracted from the installation after cleaning. The dry cleaner is structured to clean the plate using vibrations and shocks in a first confinement enclosure. The wet cleaner is structured to clean the plate using at least one liquid in a second confinement enclosure. The conveyor system is structured to transport the plate between the dry cleaner, the wet cleaner, and the exit lock.

First claim

The invention claimed is:

1. An installation for cleaning a plate used in an additive manufacturing process performed using a powder, the installation comprising:
an entry lock through which a plate that is to be cleaned is accepted into the installation;
an exit lock through which the plate is extracted from the installation after cleaning;
a dry cleaner comprising a first confinement enclosure in which the dry cleaner cleans the plate using vibrations and shocks;
a wet cleaner comprising a second confinement enclosure in which the wet cleaner cleans the plate using at least one liquid;
a conveyor system that transports the plate between the dry cleaner, the wet cleaner, and the exit lock.

2. The installation according to claim 1 , wherein the second confinement enclosure of the wet cleaner includes therein a washing station, which washes the plate with a washing liquid, and a rinsing station, which rinses the plate with a rinsing liquid.

3. The installation according to claim 2 , wherein the washing station includes:
a tank filled with the washing liquid, and
an emitter that emits ultrasound waves into the washing liquid.

4. The installation according to claim 2 , wherein the wet cleaner includes a drying station in the second confinement enclosure.

5. The installation according to claim 1 , wherein the conveyor system transports the plate from the exit lock to the first confinement enclosure of the dry cleaner.

6. The installation according to claim 1 , wherein the conveyor system includes:
a first conveyor that transports the plate: from the first confinement enclosure of the dry cleaner to the second confinement enclosure of the wet cleaner device, and from the second confinement enclosure of the wet cleaner to the first confinement enclosure of the dry cleaner; and
a second conveyor that transports the plate: from the second confinement enclosure of the wet cleaner to the exit lock, and from the exit lock to the second confinement enclosure of the wet cleaner.

7. The installation according to claim 1 , further comprising:
at least one storage area that temporarily stores a plurality of plates; and
a manipulator arm that moves the plate between the dry cleaner, the wet cleaner, the conveyor system, and each of the at least one storage area,
wherein the conveyor system includes a conveyor that transports the plate: from the first confinement enclosure of the dry cleaner to the exit lock, and from the exit lock to the first confinement enclosure of the dry cleaner.

8. The installation according to claim 1 , further comprising a protective enclosure that confines therein an entirety of the installation.

9. The installation according to claim 1 , wherein the installation comprises an enclosure,
wherein the entry lock is disposed on a wall of the enclosure,
wherein the exit lock is disposed on a wall of the enclosure, and
wherein the conveyor system comprises a belt conveyor.
