Abstract

In an automated production process, an IBM 7535 robot locates a keyboard on a special XY table and then moves the table to accurately index the keyboard under a fixed inspection camera. A hollow drive sleeve attached to the robot arm locates over a drive shaft on the table to provide a coupling for X and Y movements. In a production process, there is a station illustrated by Fig. 1 plan and Fig. 2 side elevation. IBM 7535 robot 1 is mounted on base 2 together with XY table 3. Robot 1 has jointed arms 4,5. XY table 3 is moved by robot 1 via coupling 6, and is supported by linear bearings 7,8 on the X and Y axes, respectively. Figs. 3 and 4 show coupling 6 in detail. Drive sleeve 9 is mounted on robot 1 Z-shaft 10 and has an accurately machined bore 11.

Use of Robot to Drive X-Y Table

In an automated production process, an IBM 7535 robot locates a keyboard on a special XY table and then moves the table to accurately index the keyboard under a fixed inspection camera. A hollow drive sleeve attached to the robot arm locates over a drive shaft on the table to provide a coupling for X and Y movements. In a production process, there is a station illustrated by Fig. 1 plan and Fig. 2 side elevation. IBM 7535 robot 1 is mounted on base 2 together with XY table 3. Robot 1 has jointed arms 4,5. XY table 3 is moved by robot 1 via coupling 6, and is supported by linear bearings 7,8 on the X and Y axes, respectively. Figs. 3 and 4 show coupling 6 in detail. Drive sleeve 9 is mounted on robot 1 Z-shaft 10 and has an accurately machined bore 11. Drive shaft 12 is fixed to XY table 3 and has flat topped spherical end 13. When Z-shaft 10 is moved down, bore 11 engages on spherical end 13 to complete coupling 6. In operation, robot 1 uses a dual-purpose tool. A pneumatic gripper transfers a keyboard from a conveyor to a special fixture on XY table 3. Then robot 1 positions drive sleeve 9, which is in the center of the dual-purpose tool, to engage drive shaft 12. Robot 1 now moves XY table 3 under program control to accurately indexed positions under an inspection table. The advantage of this arrangement is that the robot loads/unloads the keyboard and drives the table in an application where accurate XY alignment and indexing wo...
