Abstract
Abstract A drive mechanism for the assembly table of an electrical component insertion machine having a motor driven roller engaging the peripheral edge of a disc on the table. A latch mechanism is located on the table for engaging a latch block on the table disc, the latch mechanism being releasable in response to a program control to permit the table disc to rotate and at the same time energize the motor driven roller to rotate the table disc. The disc can be rotated in either direction.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
161 words
A table adapted to support printed circuit boards for assembly of electrical components to the board, comprising: a. a support plate having a circular opening; b. a disc rotatably supported in said plate opening; c. a drive mechanism for rotationally driving said disc; d. a latch mechanism responsive to a control means for locking said disc against rotation and releasing said disc for free rotational movement; e. release means on said latch mechanism to cause actuation of said drive mechanism to rotate said table disc, f. said latch mechanism being carried on said plate and includes a plunger positioned into and out of engagement with a block carried on said disc, g. said latch mechanism having a pair of linkages positioned by solenoids to position said plunger, h. said linkages including latch portions positionable against said block to stop the rotation of said disc, and i. said linkages having surfaces coacting with said plunger to retract said plunger from said block.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
26 words
The table of claim 1 in which said plunger when positioned out of engagement with said block operates a switch permitting operation of said drive mechanism.
Claim 4
Dependent Claim
25 words
The table of claim 1 in which said drive mechanism is a motor driven roller in frictional engagement with the peripheral edge of said disc.
