The present invention relates to a design support system constructed so as to comprise a manufacturing line information preparation section and an output section. On the basis of element types selected by a selection section as arbitrary element types to be used for constituting a manufacturing line, the manufacturing line information preparation section prepares information about the manufacturing line by means of acquiring information about element types stored in an element type database beforehand. The output section can output the information about the manufacturing line prepared by the manufacturing line information preparation section. A manufacturing line including a plurality of steps is efficiently examined, determined, and established, thereby shortening the time required to design and manufacture the manufacturing line and curtailing manufacturing costs.

Design support system

An apparatus combining a high-speed high-precision characteristic equivalent to that of a die bonder and a flexibility of coping quickly with a process variation and product variation along with size reduction and economics. This apparatus comprises a base unit including a body containing a device to be used in common among a plurality of processes for mounting and assembling parts, a mechanism for conveying a workpiece in a predetermined conveying direction and a mechanism for positioning the workpiece, a dedicated unit including an end effector, and a selected mechanism unit including a mechanism for moving the end effector in two axial directions perpendicular to the predetermined conveying direction to adjust a relative position between the end effector and the workpiece or a part. The moving mechanism is interchangeably attached on the base unit, and the end effector is interchangeably attached on the moving mechanism.

Parts mounting and assembling apparatus

A disk apparatus has a rotatable actuator adapted to magnetically latch in a predetermined stop position when the disk apparatus is not operating. The actuator rotates about a rotating or swinging shaft and includes a coil arm having a latch magnet. The coil arm is adapted to pass between opposing permanent magnets when the actuator rotates about the rotating or swinging shaft. When the actuator is in the stop position, the latch magnet is outside of the area between the permanent magnets, therefore generating a repulsive force between the latch magnet and permanent magnets, inducing the actuator to magnetically latch. When the disk apparatus is operating, the latch magnet travels between the permanent magnets, resulting in opposing repulsive magnetic forces having equal magnitudes which cancel each other, maintaining the actuator's attitude without rotating it. In this manner, the latch magnet does not interfere with the operation of the actuator, and locks the actuator in a stop or park condition when the disk apparatus is not operating.
