Abstract: A clinch mechanism for assembling a printed circuit board with electronic components includes a drive shaft configured to move along a vertical axis, a stationary anvil configured to remain stationary during movement of the drive shaft, a cutter having a cutting tip, and a toggle configured to rotate about a toggle rotation axis that includes an involute gear shaped tooth configured to roll across an involute trapezoidal slot of the cutter in order to impart movement on the cutter relative to the stationary anvil. Movement of the drive shaft along the linear axis is configured to move the cutter relative to the stationary anvil, and to move the cutting tip across the stationary anvil to cut an electronic lead located between the cutting tip and the stationary anvil, and to rotate the toggle about the axis.
