Patents by Inventor Lee Kwang Heng

Lee Kwang Heng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9620398
    Abstract: An apparatus for handling or transferring a semiconductor component. The apparatus comprises a first structure and a second structure coupled thereto. The first structure and the second structure define a vacuum chamber therebetween. The second structure comprises at least one module coupled thereto. Each module comprises a passageway defined therethrough. Vacuum is applied through the passageway for facilitating pick up of the semiconductor component at a first position and for securing the semiconductor component to the module during displacement of the module from the first position to a second position. The apparatus comprises a plunger. Displacement of the plunger from a retracted position to an extended position impedes fluid communication between the passageway of the module and the chamber. Displacement of the plunger to the extended position further causes purging of air through the passageway of the module to thereby detach the semiconductor component from the module.

  • Patent number: 9524897
    Abstract: An end handler and method for processing a device are presented. The end handler includes a mating portion for mating with a tool and a support portion for supporting a film frame on a support surface. The support portion includes a support base section, extension sections extending from the support base section, and vacuum ports on the support surface for facilitating mating of the film frame on the support surface. Each of the vacuum port includes at least one reservoir having at least one vacuum opening in fluid communication with at least one vacuum source. The vacuum ports being configured to principally maintain a slimmest profile with strongest suction force possible.

  • Patent number: 8834091
    Abstract: A system and method for transferring component panes from a component pane storage station to a vacuum table assembly are disclosed. The system includes a number of component pane handlers, for instance two handlers, and a pick and place mechanism or arm. The handler transfers the component panes from the station to the mechanism. The system includes an alignment module configured to facilitate spatial alignment of the component pane while the component pane is coupled to the handler. The module can be carried by the mechanism. Spatial alignment of the component pane can be substantially completed before transfer of the component pane from the handler to the mechanism. The mechanism includes a set of vacuum elements or pads that enables pick up of the component pane from the handler as well as release and pick up of the component pane at the vacuum table assembly.

  • Patent number: 8744617
    Abstract: A component pane handling apparatus configured to handle component panes of multiple different sizes is disclosed. The apparatus includes at least one component pane capture element that can be displaced between a number of different positions, each position corresponding to a particular component pane size. Therefore, the at least one component pane capture element can be positioned to different positions for allowing handling of component panes of corresponding sizes. The apparatus also includes a position alignment mechanism configured to control displacement of the at least one component pane capture element to the different positions. The apparatus can also include one displacement arm coupled to the component pane capture element. The displacement of the component pane capture element can be effectuated by a displacement of at least a portion of the displacement arm. A method for handling component panes of multiple sizes is also included in this disclosure.
