Abstract

A low profile, vacuum-actuated disk pick-up head suitable for robotic applications is illustrated. In Fig. 1, the pick-up head is shown with two disks 12 and 13, one of which is axially displaced from the retained position to expose the head structure. The pick-up head 4 has a groove 5 and a contact surface 6 with vacuum opening 7 in surface 6 and vacuum opening 8 along a portion of the back wall of groove 5. Individually controlled vacuum suppliers 10, 11 for the openings at opposite sides of the head are shown in Fig. 2, and the common vacuum passage 9 to both openings 7 and 8 at one side of the head is illustrated in the phantom view portion of Fig. 3. A support arm 18 extends between pick-up head 4 and the robotic interface 19.

Double Sided Disk Pick-Up Head

A low profile, vacuum-actuated disk pick-up head suitable for robotic applications is illustrated. In Fig. 1, the pick-up head is shown with two disks 12 and 13, one of which is axially displaced from the retained position to expose the head structure. The pick-up head 4 has a groove 5 and a contact surface 6 with vacuum opening 7 in surface 6 and vacuum opening 8 along a portion of the back wall of groove 5. Individually controlled vacuum suppliers 10, 11 for the openings at opposite sides of the head are shown in Fig. 2, and the common vacuum passage 9 to both openings 7 and 8 at one side of the head is illustrated in the phantom view portion of Fig. 3. A support arm 18 extends between pick-up head 4 and the robotic interface 19. This arm 18 also serves as a dual vacuum manifold between vacuum openings 7 and 8 and a source of vacuum. In operation, a disk is received with the chamfered periphery in groove 5 and the surface 6 adjacent the inner diameter and retained by applying vacuum through passage 9 from supply 10. The disks are retained by contacting the periphery and a portion of the inner diameter, and thus do not engage any portion of the surface that will be a part of the data storage area of the completed disk. The pick-up head 4 has a low profile between surfaces 15 and 16 and is of symmetrical design. By fabricating the head of plastic, light weight and increased robotic payload are achieved, and the lack of moving parts...
