Abstract

A system for polishing the edge of a mobile device is shown and described. The system includes a robot arm which is configured to grab a mobile device. The robot arm is configured to position the mobile device against at least one polishing wheel of a polishing device using a desired force. The system further includes the use of at least one polishing compound. In some instances, the at least one polishing compound is automatically applied to the at least one polishing wheel. In many of these instances the polishing compound is applied at a specific force and for a specific amount of time, ensuring only a desired amount of compound is applied. The system is contained within a chamber having at least one door configured to allow access to the interior of the chamber.

First claim

What is claimed:

1. A system for polishing the edges of an electronic device, the system comprising:
a chamber comprised of a frame having a plurality of sidewalls secured thereto;
a robot arm configured to secure to and move an electronic device;
a polishing machine secured to the frame within range of the robot arm;
a polishing compound plate secured to a pneumatic actuator which is configured to raise and lower the polishing compound plate;
at least one polishing compound located on the polishing compound plate,
wherein, polishing compound is applied to the machine by extension of the pneumatic actuator.

2. The system of claim 1 further comprising at least one electronic device slot secured to the frame within the chamber.

3. The system of claim 1 further comprising at least one door configured to allow access to the interior of the chamber.

4. The system of claim 1 further comprising a computer operably coupled to a robot controller.

5. The system of claim 1 further comprising at least one human machine interface (HMI) operably coupled to the system.

6. The system of claim 5 , wherein the HMI is configured to display system information.

7. The system of claim 1 wherein the robot arm has an electronic gripper secured to the end which is configured to secure to an electronic device.

8. The system of claim 7 further comprising a stabilizer secured to the gripper, wherein the stabilizer is configured to rest against at least one side of the electronic device;
the stabilizer is secured to the electronic gripper perpendicular to the electronic gripper, wherein the stabilizer includes at least one portion on either side of the electronic gripper.

9. The system of claim 1 , wherein, polishing compound is applied to the machine by extension of the pneumatic actuator.
