Patent number: 7568280Abstract: A package removal device is for removing a package (5) from a component band (1) to expose a carrier band (2). The package removal device includes a stand (10), a first scrolling unit includes a first gear (52), and a second scrolling unit includes a second gear (85). The stand includes a platform (12) with an import end (14a) and an export end (14b). The export end includes a locating gear (18) mounted thereon, a first exit (24), and a second exit (22). The component band is separated into the package and the carrier band in the export end. The first gear meshes with the second gear to output the package from the first exit. The locating gear engages the carrier band to output the carrier band from the second exit.Type: GrantFiled: December 21, 2005Date of Patent: August 4, 2009Assignees: Hong Fu Jin Preicision Industry (Shen Zhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Zhao-Lue Zeng, Hsuan-Jen Kung, Jin-Yue Kang, Yuan-Chiu Lin

Patent number: 7480986Abstract: An apparatus for feeding components from a packaged component band includes a stand defining a platform allowing the packaged component band passing therealong, a first guiding unit installable to the stand beside the platform, and a second guiding unit installable to the stand next to the another end of the platform. The first guiding unit is urged to remove a package from the packaged component band to expose components at one end of the platform and guides the package toward another end of the platform. The second guiding unit accepts the package from the first guiding unit and accelerates movement of the package passing therethrough. The second guiding unit includes a first friction pulley urged to rotate, and a second friction pulley rotatably movable together with the first friction pulley and engagable with the package when the package engagably passes therethrough.Type: GrantFiled: March 3, 2006Date of Patent: January 27, 2009Assignees: Hong Fu Jin Precision Industry (Shenzhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Zhao-Lue Zeng, Hsuan-Jen Kung, Yuan-Chiu Lin

Patent number: 6798088Abstract: The structure for symmetrically disposed linear motor operated tool machine comprises two parallelly erected sustaining walls, a movable gantry, a sliding saddle, a tool spindle, and a weight compensation device. At both sides of the movable gantry between the sustaining walls, between the gantry and the sliding saddle, and between the tool spindle and the sliding saddle, a pair of linear motors is symmetrically disposed such that the armature reaction between the winding and magnet is compensated each other by the opposite one therefore any possible deformation force to the tool machine structure is eliminated.Type: GrantFiled: November 7, 2002Date of Patent: September 28, 2004Assignee: Industrial Technology Research InstituteInventors: Chin-Mou Hsu, Hsuan-Jen Kung, En-Sheng Chang
