Abstract

An apparatus for automated chemical vapor processing. The apparatus includes a chemical vapor processing chamber to treat articles with surface-smoothing chemical vapor and an article loading chamber to receive articles pending treatment by the chemical vapor processing chamber. The apparatus further includes an automated conveyor to move the articles between the article loading chamber and the chemical vapor processing chamber. The apparatus further includes an air lock to connect the article loading chamber to the chemical vapor processing chamber, and a controller to control the automated conveyor to move the articles between the article loading chamber and the chemical vapor processing chamber, and to control the air lock to seal the chemical vapor processing chamber from the article loading chamber when the automated conveyor is not moving articles between the article loading chamber and the chemical vapor processing chamber.

First claim

The invention claimed is:

1. An apparatus comprising:
a chemical vapor processing chamber to treat articles with surface-smoothing chemical vapor;
an article loading chamber to receive the articles pending treatment by the chemical vapor processing chamber;
an automated conveyor to move the articles between the article loading chamber and the chemical vapor processing chamber;
an air lock to connect the article loading chamber to the chemical vapor processing chamber, the air lock comprises a door and a pneumatic seal, the pneumatic seal to inflate to seal the door and to deflate to allow the door to open; and
a controller to:
control the automated conveyor to move the articles between the article loading chamber and the chemical vapor processing chamber; and
control the air lock to seal the chemical vapor processing chamber from the article loading chamber when the automated conveyor is not moving the articles between the article loading chamber and the chemical vapor processing chamber.

2. The apparatus of claim 1 , wherein the controller is further to control the air lock to open when the automated conveyor is moving the articles between the article loading chamber and the chemical vapor processing chamber.

3. The apparatus of claim 1 , wherein the controller is further to:
track time spent by the articles in the chemical vapor processing chamber; and
control the automated conveyor to retrieve the finished articles from the chemical vapor processing chamber after pre-determined processing times.

4. The apparatus of claim 1 , wherein the article loading chamber comprises a chemical vapor remover to remove chemical vapor from the article loading chamber.

5. The apparatus of claim 4 , wherein the chemical vapor remover comprises a chemical vapor scrubber.

6. An apparatus comprising:
a chemical vapor processing chamber;
an article loading chamber connected to the chemical vapor processing chamber by an air lock to receive articles pending treatment by the chemical vapor processing chamber and to provide access to the articles finished treatment by the chemical vapor processing chamber, the article loading chamber including a plurality of access ports to receive the articles pending treatment and to provide access to the articles finished treatment;
an automated conveyor to move the articles between the article loading chamber and the chemical vapor processing chamber; and
a controller to:
control the automated conveyor to place the articles from the article loading chamber into the chemical vapor processing chamber;
track time spent by the articles in the chemical vapor processing chamber; and
control the automated conveyor to retrieve the finished articles from the chemical vapor processing chamber after pre-determined processing times.

7. The apparatus of claim 6 , wherein the chemical vapor processing chamber includes a sensor to measure a processing condition in the chemical vapor processing chamber, and the controller is further to record the processing condition in a database.

8. The apparatus of claim 6 , wherein the controller is further to label each article based on a particular access port through which the article was received and to track a position of each article in the apparatus using a label of the article.

9. The apparatus of claim 6 , wherein the controller is further to restrict access through the access ports when the automated conveyor is moving the articles between the chemical vapor processing chamber and the article loading chamber.

10. The apparatus of claim 6 , wherein the article loading chamber includes a sensor to detect chemical vapor in the article loading chamber, and the controller is further to restrict access through the access ports when the sensor detects an amount of chemical vapor above a threshold amount.

11. An apparatus comprising:
a chemical vapor processing chamber to treat articles with surface-smoothing chemical vapor;
an article loading chamber to receive the articles pending treatment by the chemical vapor processing chamber and to provide access to the articles finished treatment by the chemical vapor processing chamber;
an automated conveyor to place the articles into the chemical vapor processing chamber and to retrieve the articles from the chemical vapor processing chamber;
an air lock to seal the article loading chamber from the chemical vapor processing chamber when the automated conveyor is inactive; and
a controller to track time spent by the articles in the chemical vapor processing chamber and to cause the automated conveyor to retrieve the finished articles from the chemical vapor processing chamber according to a chemical vapor treatment schedule,
wherein the air lock comprises a pneumatic seal controllable by the controller to inflate to seal the chemical vapor processing chamber from the article loading chamber.

12. The apparatus of claim 11 , wherein the controller further controls a processing condition in the chemical vapor processing chamber.
