FIELD OF INVENTIONThe present invention relates generally to the assembly of electronic and optical devices, and more specifically, to the assembly of electronic and optical devices at oblique angles.
DESCRIPTION OF RELATED ARTPrevious electronic assembly tools are designed to assemble components on horizontal surfaces. Such tools are often capable of aligning components in an x-y plane parallel to a planar working surface or jig. Such tools are capable of applying a precise force while assembling the components along a z-axis, normal to the x-y plane.
BRIEF SUMMARYAccording to one embodiment of the present invention, a method for operating an assembly tool includes deposing a first component on an assembly surface with a first tool tip of a manipulator having a range of motion defined by a plane and an axis that is substantially normal to the plane, deposing a second component on the assembly surface, changing an orientation of the assembly surface relative to the axis from a first orientation to a second orientation, lifting the first component from the assembly surface with a second tool tip of the manipulator, and deposing the first component on the second component.
According to another embodiment of the present invention a method for operating an assembly tool includes deposing a first component on an assembly surface with a first tool tip of a manipulator having a range of motion defined by a plane and an axis that is substantially normal to the plane, deposing a second component on the assembly surface, wherein the second component includes a fiber portion, the fiber portion of the second component engaging a corresponding groove in the first component, changing an orientation of the assembly surface relative to the axis from a first orientation to a second orientation, and applying a force with a second tool tip to the first component along the axis.
Additional features and advantages are realized through the techniques of the present invention. Other embodiments and aspects of the invention are described in detail herein and are considered a part of the claimed invention. For a better understanding of the invention with the advantages and the features, refer to the description and to the drawings.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGSThe subject matter which is regarded as the invention is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The forgoing and other features, and advantages of the invention are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
With reference now to
The use of the assembly tool 100 described above is effective when assembling components having substantially planar mating surfaces that may be assembled by applying a force substantially normal the planar surfaces. However, it is desirable to assemble some components by applying a force at an oblique angle to the mating surfaces. The assembly tool 100 is designed to apply a precise force along the Z-axis, as opposed to applying a precise force in the X-Y plane, and typically does not provide adequate control of a force applied in the X-Y plane. Thus, a method for assembling components by applying a force at an angle oblique to the substantially planar mating surfaces is desired.
Methods and apparatuses operative to apply a precise force at an oblique angle relative to one of the mating surfaces of components are described in
The jig 302 of the illustrated embodiments may include any suitable assembly having an assembly surface 307. The jig 302 may include, for example a planar assembly surface 307 arranged on an actuator that is operative to change the orientation of the assembly surface 307 relative to the Z-axis of motion of the manipulator 102 from an orthogonal orientation to an oblique angle that is parallel to the engagement surface 401 of the tool tip 402.
The components 101 and 203 may include any type of components including, for example, electronic, or electrical components, or optical components such as optical fiber array packaging components.
