Making integral heat spreader by coining |
摘要 |
A method and apparatus for automatically separating blanks from a copper strip (200) and coining heat spreader lids (400) from the blanks. A high speed blanking structure (208) severs single rectangular or square blanks (212) from the copper strip. The blanks are loaded into a cartridge (214), and placed in a blanks hopper (213). The blanks are transferred from the hopper to a rotatable turret (217). The turret rotates to move a blank to a coining die cavity of a coining press (305). The blank is coined to form a lid and returned to the turret to be delivered to an unload station where the lid is dropped onto a conveyor (310). The conveyor transports the lid to a deburr and clean station (610).
