20140131423 | FETCHING MECHANISM AND AUTOMATIC WELDING SYSTEM USING THE SAME - A fetching mechanism includes a support base, a fetching member positioned on the support base and an adsorbing assembly. The adsorbing assembly is positioned on the support base and is spaced from the fetching member. The adsorbing assembly includes a driving member positioned on the support base and an adsorbing member driven by the driving member. The fetching member fetches one welding member, the adsorbing member is driven by the driving member to extend out and adsorbs the workpiece, and the adsorbing member is driven to drawback until each welding member attaches the workpiece. The application also supplies an automatic welding system using the fetching mechanism. | 05-15-2014 |
20140137706 | SCREW LOCKING DEVICE - A screw locking device includes a feeding mechanism, a conveying mechanism, and a pneumatic screw driver. The conveying mechanism includes a base, a pneumatic driver slidably mounted on the base, a pair of blocking members slidably mounted on the base, a conveying bridge, a flexible tube, and a controller. Each blocking member includes a blocking end positioned below the pneumatic driver. The conveying bridge communicates with the feeding mechanism, and extends to the blocking ends. The flexible tube aligned with a gap between the blocking ends, and communicates with the pneumatic screw driver. | 05-22-2014 |

20120113639 | LIGHT EMITTING DIODE DEVICE WITH EFFECTIVE HEAT DISSIPATION - The present disclosure relates to light emitting diode (LED) devices and methods for fabricating the same. An LED device includes a housing adapted to combine a heat sink with a vapor chamber to form an enclosed space interposed therebetween. The LED device includes light emitting diode modules attached to the housing adjacent to the vapor chamber. The vapor chamber is adapted to uniformly disperse heat generated from the LED modules within the enclosed space to form a uniform temperature field on the heat sink to thereby provide effective heat dissipation. | 05-10-2012 |
20130155673 | LED LIGHTING APPARATUS WITH FLEXIBLE LIGHT MODULES - The present disclosure involves a street light. The street light includes a base, a lamp post coupled to the base, and a lamp head coupled to the lamp post. The lamp head includes a housing and a plurality of LED light modules disposed within the housing. The LED light modules are separate and independent from each other. Each LED light module includes an array of LED that serve as light sources for the lamp. Each LED light module also includes a heat sink that is thermally coupled to the LED. The heat sink is operable to dissipate heat generated by the LED during operation. Each LED light module also includes a thermally conductive cover having a plurality of openings. Each LED is aligned with and disposed within a respective one of the openings. | 06-20-2013 |
