20080223905 | Fixing structure for printed circuit board of micro motor - The present invention relates to a fixing structure for printed circuit board (PCB) of micro motor, including a base and a PCB. The base has a shaft tube disposed centrally therein; at least a circuit board fixing pin is protruded beyond the base peripheral to the shaft tube; the PCB has a center hole for the shaft tube to be inserted in, and the diameter of the center hole shall be close to but not less than the outer diameter of the shaft tube; each circuit board fixing pin corresponds to a through hole disposed on the center of the PCB. Sensing plates are prevented from dropping to secure the motor to stably rotate; the circuit board fixing pin, after passing through the through hole, is fixed by an adhesive or a soldering means to make the PCB and the base perfectly fit and free from warp and vibration. | 09-18-2008 |
20080272178 | VACUUM WIRE TENSIONER FOR WIRE BONDER - A wire tensioner is provided for a wire bonder, the wire tensioner comprising a tubular body having a bore through which bonding wire is receivable and a bore outlet at an end of the tubular body from which the bonding wire is extendable towards a bonding tool. A chamber is formed next to the bore outlet that substantially encloses the bore outlet, the chamber including an air inlet connected to it that is operative to introduce clean air into the chamber. A vacuum outlet is connected to a side of the tubular body and is in fluid communication with the chamber via the bore, the vacuum outlet being operative to draw air from the bore outlet through the bore whereby to pull the wire. | 11-06-2008 |
20090008427 | Driving unit of welding equipment - There is provide a driving unit of welding equipment capable of surely stopping turning of a pressure application shaft while shortening the entire length of welding equipment without enlarging a hole diameter of a rotary shaft of a motor, thereby rendering a welding gun small-sized, lightweight and compact as a whole. The driving unit of welding equipment provided with the pressure application shaft that is driven by the motor and has a portion to be drawn into the motor, wherein the rotary shaft of the motor is formed of a hollow shaft, a screw shaft is fixed to the rotary shaft, and a nut to be threaded with the screw shaft is provided in the pressure application shaft, characterized in that the pressure application shaft is formed of a ball spline shaft and a part or whole of a ball spline bearing is housed in the rotary shaft. | 01-08-2009 |
20090236402 | Soldering Machine Comprising A Soldering Module And At Least One Soldering Station That Is Mobile And Exchangeable Insertable Into The Soldering Module - A soldering machine for soldering components which are mounted on a circuit board contains a soldering module and comprises at least one soldering station which is mobile and exchangeably insertable in the soldering module. The soldering station and the soldering module are equipped with means for mutual alignment and with female or male plugs, which fit with one another and which terminate supply lines for goods. When inserting the soldering station in the soldering module said means align the soldering station in relation to the soldering module. Preferably, the soldering machine is composed of modules which are situated one behind another in the transport direction and are removably connected to one another. Each module comprises an own transport system. | 09-24-2009 |
20100187287 | APPARATUS FOR APPLYING METALLIC CLADDING TO INTERIOR SURFACES OF PIPE ELBOWS - An apparatus for applying a helical cladding bead to the interior surface of a pipe elbow has a rotor mounted to an elbow carriage so as to be rotatable about a primary axis. The elbow carriage is longitudinally movable parallel to the rotor's rotational axis. A radially-movable elbow collar is mounted to the rotor, and has means for mounting a first end of a pipe elbow. The second end of the elbow passes through a stationary frame with centering means for keeping the elbow's curved centerline tangential to the primary axis. A weld arm, extending from a weld arm carriage into the second end of the elbow, is sinuously configured so that it will not interfere with the elbow. The weld arm is rotatable about the primary axis in coordination with the rotor. A weld head is mounted at the extending end of the weld arm so as to remain spatially fixed regardless of rotation of the weld arm. An integrated drive mechanism rotates the rotor, moves the elbow carriage longitudinally, moves the elbow cradle radially, and rotates the weld arm in synchronization with the rotor, all in a coordinated fashion such that the elbow's center of rotation orbits around the primary axis in a plane perpendicular thereto. The elbow moves through the stationary frame at an average rate equal to one weld bead width per rotation, thus resulting in the deposition of a continuous helical weld bead cladding the interior surfaces of the elbow. | 07-29-2010 |
