Abstract

Claims (31)

1 . A method for cleaning an electronic device with dry ice, the method comprising:

providing a first robotic arm, having interchangeable tool heads comprising a first tool head and a second tool head;

placing an electronic device in a first location;

securing the electronic device to the first tool head of the first robotic arm;

cleaning the electronic device by removing the electronic device from the first location to a second location and applying dry ice to five sides of the electronic device via a dry ice nozzle, wherein the dry ice nozzle is secured to the second tool head and the second tool head is removably secured to a tool head mount positioned adjacent to the first robotic arm;

wherein the first robotic arm moves the electronic device into a stream of dry ice sprayed by the dry ice nozzle which remains stationary in the tool head mount;

exchanging the tool heads on the first robotic arm, wherein the first robotic arm exchanges the first tool head for the second tool head;

applying dry ice to a final side of the electronic device using the first robotic arm and the second tool head; and

applying air to each side of the electronic device.

2 . The method of claim 1 , further comprising entering the electronic device into a tracking system.

3 . The method of claim 1 , wherein the electronic device is moved into the first location via a conveyor.

4 . The method of claim 1 , further comprising determining a flow rate and particle size of the dry ice to be applied.

5 . The method of claim 1 , further comprising determining a type of electronic device.

6 . The method of claim 1 , further comprising selecting a cleaning pattern based on a cleaning type desired.

7 . The method of claim 5 , further comprising determining a cleaning pattern based on the type of electronic device.

8 . A method for cleaning an electronic device with dry ice, the method comprising:

providing a first robotic arm, having interchangeable tool heads comprising a first tool head and a second tool head;

placing an electronic device in a first location, wherein the first location is on a first conveyor;

removing the electronic device from the first conveyor via the first robotic arm, wherein the first robot arm has the first tool head secured thereto;

cleaning the electronic device by applying dry ice to each side of the electronic device via a dry ice nozzle, wherein the dry ice nozzle is secured to the second tool head and the second tool head is removably secured to a tool head mount positioned adjacent to the first robotic arm;

wherein the first robotic arm moves the electronic device into a stream of dry ice sprayed by the dry ice nozzle which remains stationary in the tool head mount;

applying air to five sides of the electronic device;

placing the electronic device on a second conveyor such that a cleaned surface of the electronic device is placed on the second conveyor;

exchanging tool heads on the first robotic arm, wherein the first robotic arm exchanges the first tool head for the second tool head;

applying, for a second time, dry ice to the electronic device using the first robotic arm and second tool head, such that a final surface of the electronic device is cleaned.

9 . The method of claim 8 , wherein the electronic device is secured to the first robotic arm via the first tool head, wherein the first tool head comprises a suction device.

10 . The method of claim 8 , further comprising applying, for a second time, air to the electronic device.

11 . The method of claim 8 , further comprising entering the electronic device into a tracking system.

12 . The method of claim 8 , further comprising determining a flow rate and particle size of the dry ice to be applied.

13 . The method of claim 8 , further comprising determining a type of electronic device.

14 . The method of claim 13 , further comprising determining a cleaning pattern based on the type of electronic device.
