Head assembly for my OpenPnp mounter
By gently widening the cylinder like a trumpet, the position error in the XY direction is tolerated, and the position is fixed by grabbing it with a magnet with a hole and having the nozzle holder's flange surface contact it closely.
As a result, a positional error of about 1 mm in the XY direction can be tolerated when grabbing.
The material is SUS316 and the nozzle is grabbed by a hollow neodymium magnet.
The longer the motor is extended from the axis, the more it is affected by forces from the direction perpendicular to the axis...XY direction.
To solve the problem of shaft bending due to lateral forces, the shaft is reinforced with bearings as close to the nozzle as possible.
