PURPOSE:To improve the working efficiency and productivity of each apparatus, by providing a receiving unit and a supplying unit at the ends of a conveying path, respectively, and providing a unit for temporarily storing products in an intermediate position between those apparatuses. CONSTITUTION:A lead frame is fed by a pin 3-3 from a magazine 3-2 set on an elevator 3-1 and die bonded by a die bonding apparatus M1 at a predetermined position. The lead frame is further fed to a magazine 3-8 or 3-7 set on an elevator 3-6 in an intermediate position between the apparatus M1 and a wire bonding apparatus M2. If no preceding lead frame is present on a conveying rail 3-10, the lead frame presently fed is passed through the magazine so that wires are connected thereto by the apparatus M2 and the lead frame is received in a magazine 3-14 of a storing unit M5. If a preceding lead frame is present on the rail, however, the lead frame presently fed is received in the magazine case 3-8 and temporarily stored by the pitch operation of the elevator 3-6. According to this construction, in which the apparatuses having different functions and different working speeds are connected by means of an intermediate unit provided continuously therewith and having a storing mechanism with a certain capacity, the working efficiency and productivity of each apparatus can be improved and further the floor area can be reduced. |
