The invention discloses a glue
coating machine which comprises a
machine body, a Y-axis guide rail and a glue
coating device, wherein the Y-axis guide rail is arranged on a
machine table and extends along the Y-axis direction, the glue
coating device is arranged on the machine table and consists of an X-axis guide rail extending along the X-axis direction, a Z-axis guide rail perpendicular to the X-axis direction and the Y-axis direction, a sliding seat, a screw valve embedded in the middle of the sliding seat, a clamp type glue bucket, a screw valve controller, a heater and a temperature controller; the invention further discloses a gluing method, which comprises the following steps: putting
hot melt colloid into the clamp type glue bucket, heating through the heater to melt the
hot melt colloid, controlling the temperature of the
hot melt colloid to be unchanged through the temperature controller, regulating the screw valve through the screw valve controller to pressurize glue, controlling the motion trace of a needle head through the X-axis guide rail, the Y-axis guide rail and the Z-axis guide rail, and extruding the glue from the needle head to be evenly coated on the set trace. The glue coating machine can perform all-around
automatic dispensing, and glue does not flow vertically and does not overflow, and is high in gluing strength and sealing property, so that the effects of being dustproof, antishock, waterproof and the like can be achieved, and the pass percentage of workpieces can be increased.
