PCB (printed circuit board) processing and positioning mechanism

The utility model discloses a pcb (printed circuit board) processing and positioning mechanism, which belongs to the technical field of pcb processing, and comprises two oppositely arranged mounting plates and clamping plates positioned on the mounting plates, and at least one mounting plate is in transmission connection with a first driving mechanism for driving the mounting plates to linearly move so as to drive the two mounting plates to be close to each other or far away from each other; the area between the two mounting plates is a clamping area, the clamping plates are located in the clamping area, each mounting plate is provided with two clamping plates, and at least one clamping plate is in transmission connection with a second driving mechanism used for driving the clamping plate to move linearly so as to drive the two clamping plates to get close to or get away from each other; the first driving mechanism and the second driving mechanism are both non-manual driving structures; the mode that the firs
