Abstract
An apparatus is adapted for picking-up an integrated circuit component and is adapted to be connected to an air pump. The apparatus includes a retaining block formed with a first pipe hole and a washer receiving recess for receiving a washer. An air pipe is formed with a radially and outwardly extending rim flange at a junction of upper and lower pipe sections thereof. The lower pipe section extends sealingly through a second pipe hole in the washer and further through the first pipe hole such that the rim flange rests on top of the washer in the washer receiving recess, such that a distal lower end of the lower pipe section projects downwardly relative to the retaining block, and such that a distal upper end of the upper pipe section extends outwardly of the washer receiving recess and projects upwardly relative to the retaining block. A coupling base is mounted on top of the retaining block, and includes a horizontal base wall formed with a third pipe hole extending through top and bottom sides thereof and a spring receiving recess formed in the bottom side. A compression spring is sleeved around a guide tube that extends downwardly from the base wall and into the washer receiving recess. The compression spring has an upper spring portion disposed in the spring receiving recess, and a lower spring portion disposed in the washer receiving recess.
