ABSTRACT:
A chip transfer apparatus includes a first carrier for feeding chips and a second carrier for carrying works on it. The transfer apparatus also includes a transfer engine including two or more coaxial revolvers, which can revolve coaxially with each other. Each of the coaxial revolvers includes an end-effector for receiving a chip from the first carrier and transferring the received chip onto a work on the second carrier. The end-effectors of the coaxial revolvers are arranged in a circle coaxial with the revolvers. The end-effectors sequentially receive chips from the first carrier at substantially zero speed relative to the first carrier and transfer the received chips onto works on the second carrier at substantially zero speed relative to the second carrier. While the end-effectors are revolving, they undergo periodic speed change control for timing adjustment and speed adjustment for the chip reception and transfer.
