Description




TECHNICAL FIELD




The disclosures herein relate to the field of computer assembly tools, and, more particularly, to tools for attaching a processor bracket to a system board.




BACKGROUND




Previously, assemblers used screwdrivers (“single head screw tools”) to install processor brackets on system boards. An assembler would use the single head screw tool to install the processor bracket by individually attaching each bracket nut with the tool. This method often damaged the system board, and was time consuming because the assembler had to position the processor bracket, and individually install each bracket nut. Additionally, assemblers were often hesitant about using single head screw tools to install processor brackets because of the manual skills needed to operate the tools. Accordingly, what is needed is an apparatus and a methodology for easily installing a processor bracket on a system board that permits the simultaneous installation of a plurality of bracket nuts, and does not damage the system board during the installation process.




SUMMARY




The present embodiments include an apparatus and a method for attaching a processor bracket to a system board. The apparatus includes: a) a driver base, b) a plurality of air drivers secured to the driver base, c) a screwdriver rod, with a screwdriver head, extending from each air driver, and d) a positioning guide attached to the driver base. The method includes the steps of: a) positioning a processor bracket, having a processor bracket slot and having multiple bracket nuts, on a system board, b) positioning a positioning guide of a multiple nut driver within the processor bracket slot, c) contacting the bracket nuts with the corresponding screwdriver heads of the multiple nut driver, and d) exerting downward pressure on all the screwdriver heads.

and

FIG. 2

, a driver base


1


includes four circular air driver channels


2


that extend vertically through the thickness of the driver base


1


. The circumference of the air driver channels


2


approximately corresponds to the circumference of an air driver


3


(FIG.


6


). The air driver channels


2


include a closeable gap


4


that extends through the thickness of the driver base


1


. The driver base


1


also includes a circular base connecting rod channel


5


, located near the center of the driver base


1


, that extends vertically through the thickness of the driver base


1


. The circumference of the base connecting rod channel


5


approximately corresponds to the circumference of a connecting rod


6


(FIG.

). The driver base


1


further includes four screw channels


7


that extend through the closeable gaps


4


. Installation of a screw


8


(

FIG. 6

) within the screw channel


7


reduces the size of the closeable gap


4


.




Referring to FIG.


3


and

FIG. 4

, a positioning guide


9


includes four circular screwdriver rod channels


10


that extend vertically through the thickness of the positioning guide


9


. The circumference of the screwdriver rod channels


10


approximately corresponds to the circumference of a screwdriver rod


11


(FIG.


6


). The positioning guide


9


also contains a circular guide connecting rod channel


12


. The circumference of the guide connecting rod channel


12


approximately corresponds to the circumference of the connecting rod


6


(FIG.


6


). The positioning guide


9


further contains a screw depth opening


13


that extends from the top surface of the positioning guide


9


. The shape of a lower guide portion


14


of the positioning guide


9


approximately corresponds to the shape of a processor bracket slot (not illustrated). The lower guide portion


14


assists an assembler in positioning a multiple nut driver


15


(

FIG. 6

) correctly over a processor bracket (not illustrated), for attaching the processor bracket to a system board (not illustrated). The positioning guide


9


additionally contains four tubular extension guides


16


that extend downward from the lower edge of the screwdriver rod channels


10


. The circumference of the extension guides


16


approximately corresponds to the circumference of the screwdriver rod


11


. The extension guides

to the positioning guide


9


. A compression spring


18


encases a portion of the connecting rod


6


. The distance between the bottom of the rod nut


17


and the bottom of the screw depth opening


13


precisely corresponds to the driving distance required to install a bracket nut. The screw depth opening


13


prevents an assembler from overdriving the bracket nut, by restricting the screw depth distance.




Referring to

FIG. 6

, the multiple nut driver


15


includes a cylindrical handle


20


that can be grasped by an assembler to maneuver and operate the multiple nut driver


15


.




An eyebolt


21


connects to the top of the handle


20


, and functions as an attachment site for a tension pulley


23


. The tension pulley


23


attaches to the eyebolt


21


of the multiple nut driver


15


, and suspends the multiple nut driver


15


above the assembler's work station. Suspension of the multiple nut driver


15


allows the assembler to easily operate the multiple nut driver


15


.




An intake elbow


24


connects to the upper portion of the handle


20


, and functions as an inlet for air. An air hose


25


supplies air to the multiple nut driver


15


. Lengths of tubing


26


connect to the handle


20


at tubing connection sites


28


,


29


,


30


, and


31


, slightly below the intake elbow connection site


27


. The lengths of tubing


26


extend outwardly from tubing connection sites


28


,


29


,


30


, and


31


on the handle


20


, and connect to the top of corresponding air drivers


3


. The tubing


26


directs air flow to corresponding air drivers


3


.




An air screwdriver


32


consists of the commercially available air driver


3


(part number 2RSA-10SB, manufactured by Cleco of Houston, Tex.) and the screwdriver rod


11


, with a screwdriver head


33


. The air drivers


3


extend through corresponding air driver channels


2


in the driver base


1


. The air drivers


3


remain statically positioned within the driver base


1


upon installation of the screws


8


within the screw channels


7


(

FIG. 1

) of the driver base


1


. The screwdriver rods


11


of the air screwdrivers


32


extend through corresponding screwdriver rod channels


10


and extension guides


16


on the positioning guide


9


.




The connecting rod


6


connects the positioning guide


9


to the driver base


1


. The rod nut


17


secures the connecting rod


6


to the positioning guide


9


. The connecting rod


6


extends through the base connecting rod channel


5


on the driver base


1


. The top portion of the connecting rod


6


extends into the inner portion of the handle


20


. The compression spring


18


encases the portion of the connecting rod


6


extending between the bottom of the driver base


1


and the top of the positioning guide


9


. The tension of the compression spring


18


requires the assembler to exert some small degree of pressure in order to operate the multiple nut driver


15


.




In practice, the assembler positions a processor bracket


36


(FIG.


7


), (not shown) with multiple encapsulated bracket nuts (not illustrated), on a system board


35


(FIG.


7


). The assembler then places the positioning guide


9


of the multiple nut driver


15


within the processor bracket slot of the processor bracket, and contacts each screwdriver head


33


with a corresponding bracket nut. Holding the handle


20


, the assembler pushes down on the multiple nut driver


15


. Simultaneous pressure on all the screwdriver heads


33


triggers the flow of air to the air drivers


3


. The requirement that pressure be exerted on all the screwdriver heads


33


before air flow begins ensures that the assembler has contacted all the screwdriver heads


33


to corresponding bracket nuts before the screwdriver rods


11


begin to rotate. Air flow to the air drivers


3


causes the screwdriver rods


11


to rotate. The rotating screwdriver rods


11


simultaneously screw on the plurality of bracket nuts. The use of four separately powered air drivers


3


permits compensation for slight differences in each bracket nut. As the assembler exerts pressure and the multiple nut driver


15


installs the bracket nuts, the positioning guide


9


slides upward along the axis of the screwdriver rods


11


until the bottom of the rod nut


17


contacts the bottom of the screw depth opening


13


. After each screwdriver rod


11


stops rotating, the assembler withdraws the multiple nut driver


15


from contacting the processor bracket.




Referring to

FIG. 7

, there is illustrated a computer


34


, having a system board


35


, a processor bracket


36


, and a processor


37


. The assembler attaches the processor bracket


36


to the system board


35


using the multiple nut driver


15


of the present invention. After installation of the processor bracket


36


on the system board


35


, the assembler inserts the processor


37


into the processor bracket


36


. In an example embodiment, the processor


37


consists of a Pentium II processor. Following assembly of the processor bracket


36


and the processor


37


on the system board


35


, the assembler installs the system board


35


in the computer


34


.
