Abstract
The present invention relates to a workpiece implementation device that fabricates individual workpieces, positions them at their point of use on a component, and connects the workpieces to the components. The device further comprises an accessory assembly capable of shaping the workpieces, coating the workpieces with a solderable material, burnishing the point of use on the component, and testing the connection between the workpieces and the component. The positioning, attaching, and accessory assemblies of the workpiece implementation device are adapted to selectively perform their individual functions without the necessity of first repositioning the component or the implementation device. Accordingly, the present invention increases overall production efficiency by integrating several separate implementation tools and workstations into a single, adaptable device.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates to a device that fabricates, positions, and installs electrical terminals and hardware attachments to subject components. The device of the present invention is further capable of accomplishing optional functions, such as burnishing and electrical/mechanical-pull testing, without repositioning the device for each such optional function.




2. Description of the Prior Art




Electrical terminals must be connected to certain articles of manufacture to allow for the flow of electricity from one medium to a different medium. This is particularly true in instances where the conductive elements are embedded in or disposed on a non-conductive material, such as a silica substrate. For example, electrical terminals must be attached to glass automotive windows having embedded wire or silver oxide painted defrost grids to provide a point of input and output for electrical current.




Currently, such terminals are manufactured beginning with the step of obtaining a ribbon of copper, then cleaning, tin-plating, and reeling the ribbon. The ribbon is de-reeled, clad with a solder material on one side, and re-reeled. The ribbon of solder-clad copper is fed into a progressive stamping die that blanks out the flat terminal, then forms the terminal into its final shape. The terminals are connected to a carrier strip that is used to transfer the terminals along the multiple stations of the progressive stamping die. The progressive stamping die cuts the individual terminal off of the carrier strip at its last station. The individual terminals are optionally cleaned and tin-plated to cover the exposed copper where it was cut from the carrier strip. The individual terminals are fed by a vibratory bowl feeder into a machine that applies a flux coating to the solder-clad base of the terminal. The individual terminals are shipped loosely in a container to the fabricator.




At the fabricator, the individual terminals are attached to the subject component, usually by either manual soldering or automated soldering. In manual soldering, the individual terminals are picked at random from the container by the operator and soldered to the appropriate component. In automated soldering, the individual terminals are fed into a vibratory bowl feeder where they are oriented, fed at random into a track, and positioned in a locating fixture from which a robot withdraws the individual terminal. The robot then moves the terminal to the component and positions it to be soldered.




Although this process of production and implementation of electrical terminals is well established, it has several shortcomings that cause defects and unnecessary expense. One shortcoming of the established process is the cost of flux-coating individual terminals. The vibratory bowl feeders into which the individual terminals are loaded are frequently jammed and otherwise prevented from operating properly because the terminals become tangled. Another shortcoming of the established process is the loose packaging of the individual terminals, which causes the flux coating to be damaged. This damage can occur in shipping or in the bowl feeder used to orient the terminals in automated soldering. The damage to the flux coating reduces the ability of the terminal to adhere to the component when it is soldered. A further shortcoming of the established process is that manufacturing lot traceability is not accurate. Terminals placed in vibratory bowl feeders are moved randomly. An individual terminal that is moved through the feeder will have spent an indeterminate amount of time in the feeder. The longer a terminal spends in the vibratory bowl feeder, the more likely it is to have some or all of its flux coating removed. The problem of flux coating damage is made more difficult to identify if clear flux is used rather than colored flux. Yet another shortcoming of the established process is the expense associated with automated soldering. Separate pieces of machinery are required to orient the terminals and transfer the terminal from the locating fixture to the soldering location. A further shortcoming of the established process is the time and expense required to clean and tin plate the copper ribbon a second time to cover the copper exposed when the individual terminals are cut.




Accordingly, there is a need for an improved method and device for positioning, and installing electrical terminals and to subject components.




SUMMARY OF THE INVENTION




The present invention relates to a workpiece implementation device that fabricates individual terminals, positions the terminals at their point of use, and connects the terminals to the subject components. The present device may also include an apparatus for shaping the terminal, coating the terminal with flux, burnishing the component, attaching a terminal to the component, and testing the connection between the terminal and the component.




More specifically, the device of present invention efficiently performs the functions of several separate devices. Integrated terminals are fed into the device by a terminal feeder. A selector assembly then directs the integrated terminals from the feeder toward a punch. However, before the punch separates an individual terminal from the integrated terminals, a loader assembly grips the individual terminal. The individual terminal then separated from the integrated terminals and is moved by the loader assembly to a positioner assembly. An optional burnishing tool then burnishes the point of use on the component prior to the application of the terminal. The positioner assembly moves the individual terminal to the point of use on the subject component and the terminal is connected to the component. Finally, a terminal postponer tests the mechanical connection between the terminal and the component and an electrical testing mechanism tests the electrical characteristics of the component.




It is therefore an object of the invention to provide a device which separates integrated electrical terminals and positions the terminals at a point of use.




A further object of the invention is to provide a device which selects individual electrical terminals from integrated electrical terminals and implements them without subjecting the individual terminals to bulk storage or shipping.




A further object of the invention is to provide a device which prevents damage to the flux coating applied to soldered terminals.




A further object of the invention is to provide a workpiece attachment device that performs electrical testing and mechanical pull testing without the necessity of repositioning the device.




A further object of the invention is to provide a workpiece attachment device that allows the electrical testing function to be started while the solder connection solidifies.




A further object of the invention is to burnish the point of use on the component prior to connecting a terminal thereto without the necessity of repositioning the device.




A further object of the invention is to provide a device that allows for the implementation of workpieces and the tracing of production lots.




These and other objects of the invention will be apparent to those skilled in the art.

DESCRIPTION OF THE PREFERRED EMBODIMENT




The numeral


10


refers generally to the workpiece implementation device of the present invention. It should be understood that the present invention is well-suited for the implementation of various types of workpieces including, but not limited to, electrical terminals and hardware attachments (such as mounting points for automobile wipers, rear view mirrors, and window elevators). However, for simplicity of description, the present invention will be described as it is used to implement electrical terminals.




As shown in

FIGS. 1A

,


1


B, and


1


C, the device


10


includes a feeder assembly


12


, a soldering assembly


14


, and a burnish assembly


16


, each comprising constituent assemblies.

FIG. 2

depicts the feeder assembly


12


, which includes an infeed assembly


100


, a selector assembly


200


, a press assembly


300


, and a loader assembly


400


. The infeed assembly


100


includes an infeed mount


102


. As shown in

FIG. 3

, the infeed mount


102


has attached to one side thereof a feed tube assembly. The feed tube assembly is comprised of feed tube collet


106


, feed tube retainer


108


, and left and right feed guides


110


and


112


. The feed tube assembly directs the integrated electrical terminals


18


through the feed tube collet


106


, feed tube retainer


108


, and left and right feed guides


110


and


112


into the device


10


. The integrated electrical terminals


18


are directed down a groove


114


in the infeed mount


102


. The infeed mount


102


has attached to it on either side of groove


114


a heel spacer


116


and a blade spacer


118


. The heel spacer


116


supports a heel plate


120


, which supports infeed cover


122


. The blade spacer


118


supports a blade plate


124


. As can be seen in the drawings, the infeed cover


122


extends over the blade plate


124


. As is also evident from the drawings, the blade plate


124


is thinner than the heel plate


120


resulting in a gap


126


between the infeed cover


122


and the blade plate


124


.




The infeed assembly may also include a conventional shaping device for forming the integrated terminals


18


. Such a device (not shown) may be used to form three-dimensional terminals from a flat piece of material. The use of flat integrated terminals would allow for the reduced cost of fabrication and shipping of the terminals. Similarly, three-dimensional terminals may be formed from partially formed integrated terminals. As is known in the art, it is common for electric terminals to have ribs, channels, or the like stamped into the terminals during fabrication. Final shaping of the partially formed terminals may be completed by the conventional shaping device.




The integrated electrical terminals


18


are moved through the infeed assembly


100


by the selector assembly


200


which is shown in FIG.


4


. The selector assembly


200


includes a selector mount


202


, which is attached to the infeed mount


102


. An air cylinder linear actuator


204


is mounted on the selector mount


202


and supports a bracket


206


that may be moved toward and away from the selector mount


202


. The bracket


206


has mounted to it bearing rails


208


and indexing air cylinders


210


. The indexing air cylinders


210


are connected to finger bracket


212


, which supports bearing blocks


214


and feed finger


216


. The bearing blocks


214


are adapted to slidably engage the bearing rails


208


on the bracket


206


. The feed finger


216


is designed with a blade portion


218


that is adapted to fit into the gap


126


of the infeed assembly


100


and engage the integrated electrical terminals


18


therein.




The selector assembly


200


works in the following manner. The indexing air cylinders


210


are adapted to move the finger bracket


212


on the bearing rails


208


toward and away from the infeed assembly


100


, as shown in FIG.


5


. At the start of a cycle, the linear actuator


204


will have drawn the bracket


206


toward the selector mount


202


. The indexing air cylinders


210


will have drawn the feed finger


216


away from the infeed assembly


100


. The indexing air cylinders


210


will then move the feed finger


216


toward the infeed assembly


100


so that the blade portion


218


will engage the integrated electrical terminals


18


therein. The linear actuator


204


will then move the bracket


206


and, by necessity, the feed finger


216


away from the selector mount


202


. This action will move the integrated electrical terminals


18


along the groove


114


in the infeed mount


102


. Preferably, the integrated electrical terminals are composed of uniform individual terminals


20


connected by terminal carrier portions


22


. The feed finger


216


will, preferably, move the integrated electrical terminals


18


along the groove


114


precisely a distance equivalent to the width of an individual terminal


20


and a terminal carrier portion


22


. The indexing air cylinders


210


will then move the feed finger


216


away from the infeed assembly


100


and disengage the feed finger


216


from the integrated electrical terminals


18


. The linear actuator


204


will then draw the bracket


206


and the feed finger


216


toward the selector mount


202


to the point of origin. The cycle may then be repeated to continue the movement of the integrated electrical terminals


18


through the device


10


.




The infeed assembly


100


and the selector assembly


200


may be implemented to move individual electrical terminals


20


to the loader assembly


400


. Preferably, however, the infeed assembly


100


and the selector assembly


200


are designed to move the integrated electrical terminals


18


toward the press assembly


300


. The press assembly


300


shown in

FIGS. 6-8

includes a press frame


302


mounted on a device mount


700


. The press frame


302


has mounted to it a frame brace


304


, an upper press mount


306


, a lower press mount


308


, and a die


310


. The upper press mount


306


and the lower press mount


308


are adapted to support a press subassembly


312


.




The press subassembly


312


includes a housing


314


. The housing


314


has an aperture


316


in which a piston


318


is located. The piston


318


has an axis


320


and can move along the axis


320


within the housing


314


. The piston


318


also has a shaft


322


that extends through a spring


324


to a hydraulic cylinder


326


. The hydraulic cylinder


326


is adapted to drive the piston


318


along the axis


320


away from a starting position and the hydraulic cylinder


326


. The spring


324


is adapted to draw the piston


318


back toward the hydraulic cylinder


326


to the starting position. The piston


318


has mounted to it punch holder blocks


328


. The punch holder blocks


328


are housed within spring housing


330


and are adapted to retain a punch


332


therebetween. When the press subassembly


312


is actuated, the punch


332


is driven by the hydraulic cylinder


326


along the axis


320


from a place of origin. The spring


324


then returns the punch to the place of origin. The punch


332


is adapted to fit into an opening


334


in the die


310


.




The frame brace


304


supports an air/oil hydraulic intensifier


336


. The intensifier


336


is connected to the hydraulic cylinder


326


by a hose (not shown). The intensifier


336


provides sufficient force on the hydraulic cylinder


326


to drive the punch


332


through the material from which the integrated electrical terminals


18


are made and into the die


310


, removing carrier portion


22


and producing a separated terminal


20


.




The device


10


includes a loader assembly


400


for the handling of a separated terminal


20


. The loader assembly


400


includes a loader mount


402


. The loader mount


402


is connected on one end to the infeed mount


102


and, on its other end, has mounted to it a loader bracket


404


and a loading air cylinder


406


. The loader bracket


404


has mounted to it loader bearing rails


408


. The loading air cylinder


406


is adapted to movably receive a gripper mount


410


such that the gripper mount


410


may move toward or away from the loader mount


402


. The gripper mount


410


has attached to it loader bearing blocks


412


and an air actuated gripper


414


. The loader bearing blocks


412


are adapted to slidably receive the loader bearing rails


408


. The air-actuated gripper


414


includes opposing left and right arms


416


and


418


, respectively. Opposing left and right arms


416


and


418


each have connected to it a gripper jaw


420


and


421


, respectively. As can be seen in

FIG. 11

, opposing left and right arms


416


and


418


may be configured in an open position. The air-actuated gripper


414


draws the opposing left and right arms


416


and


418


toward each other so that the gripper jaws


420


and


422


are drawn toward each other. The gripper jaws


420


and


422


are adapted to hold a terminal


20


.




In operation, the loading air cylinder


406


maintains the gripper mount


410


in a starting position away from the loader mount


402


. In the starting position, the opposing left and right arms


416


and


418


are in an open position. The air actuated gripper


414


then draws the opposing left and right arms


416


and


418


toward each other so that the gripper jaws


420


and


422


grip terminal


20


at the end of the integrated electrical terminals


18


. The terminal


20


being held by the gripper jaws


420


and


422


is positioned on the downstream side of the die


310


. The terminal carrier portion


22


connecting the individual terminal


20


to the remainder of the integrated electrical terminals


18


is positioned directly over the opening


334


of the die


310


by the selector assembly


200


as is seen in FIG.


8


. The punch


332


is driven into the die


310


, shearing the terminal carrier portion


22


from both the individual terminal


20


and the integrated electrical terminals


18


. The gripper mount


410


is then drawn toward the loader mount


402


by the loading air cylinder


406


, thereby placing the severed terminal


20


in its point of use, or, alternatively, loading the terminal


20


into a separate apparatus for positioning the terminal


20


.




As seen in

FIGS. 2

,


11


,


12


, and


15


, the disclosed device includes a soldering assembly


14


. The soldering assembly


14


includes a rotator mount


502


, which is mounted on the infeed mount


102


. An air-actuated rotator


504


is mounted on the rotator mount


502


and has a positioner mount


506


mounted thereon that may be rotated clockwise and counterclockwise with respect to the rotator mount


502


. A parallel gripper


508


is mounted on the positioner mount


506


and has attached to it first and second parallel jaws


510


and


512


. The parallel gripper


508


is capable of moving the first and second parallel jaws


510


and


512


toward or away from each other. The first and second jaws


510


and


512


are adapted to grab, hold, and release a terminal


20


. In the soldering assembly shown in the drawings, the soldering mechanism is an intermittent microflame soldering tool, although it is contemplated that any soldering tool could be employed in the device. In the soldering assembly


14


that is shown, the positioner mount


506


has a cavity


514


therein adapted to receive an electrode base


516


and electrode clamp


518


. An electrode


520


is retained between the electrode base


516


and the electrode clamp


518


so that the terminal


20


extends entirely through the cavity


514


to protrude on the opposite side of positioner mount


506


. The intermittent microflame soldering tool shown includes fittings


522


and


524


, fitting retainers


526


and


528


, valve


530


, and burner tip


532


. The positioner mount


506


may be modified to accept any appropriate soldering mechanism.




In operation, the first and second parallel jaws


510


and


512


are drawn toward each other by the parallel gripper


508


to grasp an individual terminal


20


from the left and right gripper jaws


420


and


422


of the loader assembly


400


. The air actuated rotator


504


then rotates the positioner mount


506


so that the first and second parallel jaws


510


and


512


hold the terminal


20


at its point of use, as shown in FIG.


14


A. The solder that is integrated with the terminal


20


is then heated by the soldering tool to connect the terminal


20


to the subject component. Preferably, the terminal is fed into the device


10


having not only solder integrated therewith, but also having flux coating applied thereto. The device


10


may also include a conventional apparatus for applying a soldering related material such as a flux coating apparatus (not shown) or a conventional solder paste application apparatus (not shown). The flux coating apparatus or solder paste application apparatus will, preferably, apply materials to the terminal


20


immediately prior to the implementation of the terminal


20


.




A number of additional functions may be incorporated into the device


10


. Among the possible accessories are those shown in FIG.


2


. For example, terminal application device


10


includes a pull test and electrical test described as follows. The pull test operation utilizes the parallel gripper


508


. The gripper


508


has movable, opposing arms


510


and


512


, respectively, and is adapted to draw the opposing arms


510


and


512


toward and away from each other. Opposing arm


510


has a feature


618


in its gripper that secures terminal


20


. Opposing arm


512


has a similar feature


622


in its gripper that secures terminal


20


. A pair of air push rod cylinders


626


and


627


are mounted to the underside of the gripper


508


. The pair of air push rod cylinders


626


and


627


include push rods


628


and


629


which has pads


630


and


631


attached to its end.




In operation, the gripper


508


draws the opposing gripper arms


510


and


512


toward each other so that the gripper jaw features


618


and


622


engage a connected electrical terminal


20


. The air push rod cylinders


626


and


627


are activated so that the pads


630


and


631


at the end of the push rods


628


and


629


contact the subject component to lift the device


10


away from the subject component. The movement of the device


10


away from the subject component is restricted by the connection of the electrical terminal


20


to the subject component. If the connection between the terminal


20


and the subject component is strong enough, the device


10


will not move. If, on the other hand, the connection is weak, the force exerted by the air push rod cylinders


626


and


627


will disconnect the electrical terminal


20


from the subject component.




The pull test operation may also include an electrical connection tester. The electrical connection tester is, preferably, employed in an environment where two of the devices


10


are employed to simultaneously implement electrical terminals


20


in a single circuit. The opposing gripper arms


510


and


512


of each device


10


may be supplied with electrical connections that contact each subject terminal


20


when opposing gripper arms


510


and


512


are drawn toward each other. Each of the respective terminal grippers


508


are electrically isolated from the positioner mounts


506


via eight insulating bushings


720


.




One of the devices


10


may be adapted to provide an electrical charge that travels through the subject component to the terminal


20


that is in contact with the other of the devices


10


, via an electrical connection


710


being attached to gripper jaw


512


. The other of the devices


10


may be identically equipped with a sensor to determine whether the electrical charge has traveled from one of the subject terminals, through the circuit in the subject component to the other of the subject terminals, indicating a proper electrical connection.




The burnishing accessory


16


includes a buffer mount


638


. The buffer mount


638


is attached to the infeed assembly


100


. A buffer housing


640


is mounted to the buffer motor mount


642


. A motor mount


642


is mounted to the buffer housing


640


so that the buffer mount


638


, buffer housing


640


and motor mount


642


define a rotatable assembly. The buffer mount


638


is mounted onto a buffer rotary actuator


730


which is secured by the buffer rotary actuator mount


740


which is attached to the infeed assembly


100


. An electric motor


644


is mounted on the motor mount


642


. A burnishing wheel adapter


646


is operatively connected to the motor


644


and is housed into the chamber formed by the buffer housing


640


and the motor mount


642


. The burnishing wheel


650


is adapted to engage outer and inner wheel flanges


648


and


649


, respectively. Accordingly, the outer and inner wheel flanges


648


and


649


hold an burnishing wheel


650


there between. Rotation of the motor


644


results in the rotation of the burnishing wheel


650


. The buffer housing


640


may also have a dust hose attached to it (not shown). The dust hose may be connected to a vacuum device (not shown) to assist in the removal of dust created by the burnishing wheel


650


.




In operation, the subject component will be placed under the terminal implementation device


10


prior to the connection of the individual electrical terminal


20


thereto, as shown in FIG.


14


B. The burnishing wheel


650


will prepare the surface of the subject component for connection of the individual electrical terminal


20


. This will be accomplished by the rotation of the burnish rotary actuator


730


which will position the burnishing wheel


650


below the terminal implementation tool


10


at the location where the solder tool


14


will attach the terminal


20


to the subject component. Then the burnish operation will be performed by the rotation of the burnishing wheel


650


by the electric motor


644


. Dust generated by the contact between the abrasive wheel


650


and the surface of the subject component will be removed from the surface through the dust hose.




As can be seen from the drawings, the operational positions of the burnishing accessory


16


and the pull test-soldering assembly


14


are the same. The device


10


, therefore, does not have to be moved with respect to the subject component by either air cylinders (not shown) or by activation of a robot (not shown) for the implementation tool


10


to the burnish, solder, and test operations.




The accessories need not be positioned on a separate accessory assembly


16


as shown, but may be incorporated into other structures on the tool. As an example, it is contemplated that the air-actuated rotator


504


could be adapted to rotate burnish mount


638


to any one of three positions. In the first position, the first and second parallel jaws


510


and


512


could be positioned to receive the terminal


20


from the loader assembly


400


. In the second position, the burnishing assembly


16


could be positioned to burnish the subject component. In the third position, the terminal


20


could be positioned at its point of use having, the integral solder and pull test assembly


14


could be positioned to determine the mechanical strength and electrical performance of the connection. Obviously, other permutations of the structure could exist, and the above descriptions are not intended to limit the scope of the structure to only the described structures.




Additional conventional accessories are contemplated by this disclosure, such as a vision camera. The accessories shown are merely exemplary and do not constitute an exhaustive list of the possible structures contemplated.




The device


10


as shown is adapted to be mounted on a positioning arm (not shown). Toward this end, the device


10


includes a device mount


700


. A device attachment means


702


is mounted on the device mount


700


. The device attachment means


702


is attached to the positioning arm and allows the positioning arm to locate the device


10


as necessary.




The device


10


also includes a vertical actuator


704


. The vertical actuator


704


is attached to the press assembly


300


and the device mount


700


. The vertical actuator


704


has at least one air actuated cylinder


706


that is connected to at least one of the infeed assembly


100


, the selector assembly


200


, the loader assembly


400


, the soldering assembly


14


or the accessory assembly


16


, but, preferably to the infeed mount


102


. The air-actuated cylinder


706


is adapted to move the infeed assembly


100


, the selector assembly


200


, the loader assembly


400


, the soldering assembly


14


and the accessory assembly


16


toward and away from the subject component. This movement allows the assemblies that must contact the subject component to do so and also allows the subject component to be moved relative to the device


10


without interference, as shown in

FIGS. 14A

,


14


B,


14


C, and


15


. The movement also allows for the movement of integrated electrical terminals


18


having a flange without interference between the flange and the die


310


, as shown in FIG.


8


.




The integrated electrical terminals


18


are attached to the subject components sequentially, allowing for tracing of production lots and allowing for greater quality control. Furthermore, in instances where flux is applied to the integrated electrical terminals


18


prior to introduction into the device


10


, the flux is not removed from the terminal by bulk shipping or production machinery. The quality of the connection between the terminal and the subject component is thereby enhanced.




In the drawings and in the specification, there has been set forth preferred embodiments of the invention and although specific items are employed, these are used in a generic and descriptive sense only and not for purposes of limitation. Changes in the form and proportion of parts, as well as a substitution of equivalents, are contemplated and circumstances may suggest or render expedient without departing from the spirit or scope of the invention as further defined in the following claims.




Thus it can be seen that the invention achieves at least all of the stated objectives.
