Abstract

Claims (42)

1. A system for use in a device assembly process to aid in performing at least one device assembly operation, the system comprising:

a slider base, the slider base comprising:

a row of magnets;

an encoder strip disposed along the slider base;

a magnetically controlled slider moveably coupled to the slider base to move components of a device in the device assembly process comprising at least one device assembly operation being performed; and

a coil disposed on the magnetically controlled slider, the coil configured to:

inductively move the magnetically controlled slider relative to the magnets when driven with control signals from a controller, and

read position information from the encoder strip; and

an electronics module coupled to an end portion of the slider base, the electronics module comprising:

a driver; and

the controller including the driver, the controller configured to:

transmit to the coil, through the driver and a cable directly connected between the driver and the coil, the control signals to control movement of the magnetically controlled slider,

receive from the coil, through the driver and the cable, the position information; and

determine a position of the magnetically controlled slider from the position information.

2. The system of claim 1 , wherein the magnetically controlled slider includes a linear motor controlled slider controlled by the controller.

3. The system of claim 1 , further comprising a robotic device to perform at least two device assembly operations.

4. The system of claim 3 , wherein the at least two device assembly operations performed by the robotic device include mounting a disk to a spindle motor and mounting a spacer to the disk.

5. A method for a device assembly process to perform at least one device assembly operation, the method comprising:

moving a magnetically controlled slider coupled to a slider base to move components of the device in the assembly process, the slider base comprising:

two rows of magnets;

an encoder strip disposed along the slider base; and

a coil disposed on the magnetically controlled slider, the coil configured to:

inductively move the magnetically controlled slider relative to the magnets when driven with control signals from a controller, and

read position information from the encoder strip;

wherein a driver of the controller connects, via a cable, with the coil to transmit control signals and thereby to control movement of the magnetically controlled slider, wherein the cable extends within the slider base and the magnetically controlled slider moves components of a device in the device assembly process in which at least one device assembly operation is performed;

transmitting, with the controller and to the coil through the driver and the cable directly connected between the driver and the con, the control signals to control movement of the magnetically controlled slider,

receiving, with the controller and from the coil through the driver and the cable, the position information; and

determining, with the controller, a position of the magnetically controlled slider from the position information.

6. The method of claim 5 , wherein the magnetically controlled slider includes a linear motor controlled slider.

7. The method of claim 5 , further comprising receiving and transmitting data from and to a computing device.

8. The method of claim 5 , wherein a robotic device performs at least two device assembly operations.

9. The method of claim 8 , wherein the at least two device assembly operations performed by the robotic device include mounting a disk to a spindle motor and mounting a spacer to the disk.

10. A non-transitory computer-readable medium having one or more instructions stored thereon to control moving a magnetically controlled slider coupled to a slider base comprising two rows of magnets and an encoder strip disposed along the slider base to aid in performing at least one device assembly operation in a device assembly process, the one or more instructions executable by an electronics module coupled to an end portion of the slider base to implement functions including:

moving the magnetically controlled slider coupled to the slider base to move components of the device in the assembly process, the magnetically controlled slider being moveable between the rows of magnets;

wherein a driver of a controller connects, via a cable, with a coil disposed on the magnetically controlled slider to transmit control signals and thereby to control movement of the magnetically controlled slider, wherein the cable extends within the slider base and the magnetically controlled slider moves components of the device in the assembly process in which at least one device assembly operation is performed, wherein the coil is configured to inductively move the magnetically controlled slider relative to the magnets when driven with control signals from the controller and read position information from the encoder strip;

transmitting, with the controller and to the coil through the driver and the cable directly connected between the driver and the coil, the control signals to control movement of the magnetically controlled slider,

receiving, with the controller and from the coil through the driver and the cable, the position information; and

determining with the controller a position of the magnetically controlled slider from the position information.

11. The non-transitory computer-readable medium of claim 10 , wherein the magnetically controlled slider includes a linear motor controlled slider.

12. The non-transitory computer-readable medium of claim 10 , further comprising instructions to implement functions including receiving and transmitting data from and to a computing device.

13. The non-transitory computer-readable medium of claim 10 , wherein, a robotic device performs the at least two device assembly operations.

14. The non-transitory computer-readable medium of claim 13 , wherein the at least two device assembly operations performed by the robotic device include mounting a disk to a spindle motor and mounting a spacer to the disk.
