The invention discloses a quick-clamped PCB gluing device. The quick-clamped PCB gluing device comprises a frame, a portal, a fixture base, a positioning mechanism, an
electromagnet, a cylinder, an upper push plate, a connecting rod, a first spring, a lower push plate, a
servo motor, a lead screw, a feeding nut, a slide base and a gluing mechanism; the positioning mechanism further comprises an adjusting mechanism, a
slide plate, a limiting rod, an upper limiting plate, a second spring and a lower limiting plate; the
electromagnet is powered off; the second spring is returned to push the limiting rod to upwards move to extend outside the fixture base; a PCB to be machined is put in an area consisting of four limiting rods for positioning; the cylinder pushes the upper push plate to downwards move in place, so that the gluing mechanism is contacted with the PCB to be machined; the
servo motor drives the gluing mechanism to move; the gluing mechanism glues the surface of the PCB; and after the gluing is finished, the
electromagnet is electrified to suck with the lower limiting plate, so that the limiting rods are driven to downwards move to return, and operators can take away the glued PCB.
