An apparatus for automatic pitch conversion for pick and place heads, comprising at least one auto pitch station for adjusting a pitch in a X-coordinate direction and/or adjusting a pitch in a Y-coordinate direction of pickers/grippers of a pick and place heads; a first actuator, operated by a motor
An apparatus for automatic pitch conversion for pick and place heads, comprising at least one auto pitch station for adjusting a pitch in a X-coordinate direction and/or adjusting a pitch in a Y-coordinate direction of pickers/grippers of a pick and place heads; a first actuator, operated by a motor gear assembly of the at least one auto pitch station, wherein the first actuator changes the pitch in the X-coordinate direction distance between rows of pickers/grippers of the respective pick and place head; and a second actuator operated by the same motor gear assembly, wherein the second actuator changes the pitch in the Y-coordinate direction between the pickers/grippers within a row of the respective pick and place head. A method for automatic pitch conversion of pick and place heads and a pick and place head and a pick and place device.

1. An apparatus for automatic pitch conversion for pick and place heads, comprising: at least one auto pitch station for adjusting a pitch in a X-coordinate direction and/or adjusting a pitch in a Y-coordinate direction of pickers/grippers of the pick and place heads;a first actuator, operated by a
1. An apparatus for automatic pitch conversion for pick and place heads, comprising: at least one auto pitch station for adjusting a pitch in a X-coordinate direction and/or adjusting a pitch in a Y-coordinate direction of pickers/grippers of the pick and place heads;a first actuator, operated by a motor gear assembly of the at least one auto pitch station, wherein the first actuator comprises a first gear wheel and a first gear rack, the first actuator operatively arranged to change the pitch in the X-coordinate direction distance between rows of pickers/grippers of the respective pick and place head; and,a second actuator operated by the same motor gear assembly of the at least one auto pitch station, wherein the second actuator changes the pitch in the Y-coordinate direction between the pickers/grippers within a row of the respective pick and place head. 2. The apparatus as recited in claim 1, wherein the first actuator is a pusher which is moved along the X-coordinate direction. 3. The apparatus as recited in claim 1, wherein the second actuator is operatively arranged to translate a changeover fork along the X-coordinate direction in order to grab a single picker/gripper of a row or changing the pitch in the Y-coordinate direction. 4. The apparatus as recited in claim 1, wherein a third actuator is associated with the at least one auto pitch station for moving the pickers/grippers in a Z-coordinate direction in order to disable individual pickers/grippers. 5. The apparatus as recited in claim 4, wherein the third actuator is a shaft changeover mechanism with at least one shaft pusher which is movable in the Z-coordinate direction for pushing the pickers/grippers into a disabled position. 6. The apparatus as recited in claim 5, wherein the pusher is used to operate shaft unlock mechanism to bring at least one picker/gripper in an operating position. 7. The apparatus as recited in claim 1, wherein a first auto pitch station and a second auto pitch station are arranged opposite to each other and a shaft changeover mechanism is arranged between the first auto pitch station and the second auto pitch station. 8. The apparatus for automatic pitch conversion for pick and place heads of claim 1, wherein the second actuator comprises a second gear wheel and a second gear rack. 9. An apparatus for automatic pitch conversion for pick and place heads, comprising: a first auto pitch station and a second auto pitch station for adjusting a pitch in a X-coordinate direction and/or adjusting a pitch in a Y-coordinate direction of pickers/grippers of at least one pick and place head;a first actuator operated by a motor gear assembly of the first auto pitch station, wherein the first actuator comprises a first gear wheel and a first gear rack, the first actuator operatively arranged to change the pitch in the X-coordinate direction between rows of pickers/grippers of the respective pick and place head; and,a first actuator operated by a motor gear assembly of the second auto pitch station, wherein the first actuator comprises a first gear wheel and a first gear rack, the first actuator operatively arranged to change the pitch in the X-coordinate direction distance between rows of pickers/grippers of the respective pick and place head;a second actuator operated by the same motor gear assembly of the first auto pitch station, wherein the second actuator changes the pitch in the Y-coordinate direction between the pickers/grippers within a row of the respective pick and place head and a second actuator operated by the same motor gear assembly of the second auto pitch station, wherein the second actuator changes the pitch in the Y-coordinate direction between the pickers/grippers within a row; and,a third actuator is arranged between the first auto pitch station and the second auto pitch station for moving the pickers/grippers in a Z-coordinate direction in order to disable individual pickers/grippers. 10. The apparatus as recited in claim 9, wherein the first actuator is a pusher, wherein the pusher of the first auto pitch station is moved by the motor gear assembly of the first auto pitch station and the pusher of the second auto pitch station is moved by the motor gear assembly of the second auto pitch station along the X-coordinate direction in opposing directions. 11. The apparatus as recited in claim 9, wherein the second actuator is operatively arranged to translate a changeover fork, wherein the changeover fork of the first auto pitch station is moved by the motor gear assembly of the first auto pitch station and the changeover fork of the second auto pitch station is moved by the motor gear assembly of the second auto pitch station along the Y-coordinate direction in opposing directions in order to grab a single picker/gripper of a row of the rows of picker/grippers or changing the pitch in the X-coordinate direction. 12. The apparatus as recited in claim 9, wherein the third actuator is a shaft changeover mechanism with at least one shaft pusher which is movable in the Z-coordinate direction, for pushing selected pickers/grippers into a disabled position.
