Laser marking feeding device

A laser marking feeding device, used for multiple parts to be marked, the laser marking feeding device comprising:

• a device body, disposed with a processing area and a feeding area disposed on a side of the processing area;
• a laser marking machine, installed in the processing area;
• a transmitting mechanism, installed in the processing area and the feeding area and disposed under the laser marking machine, used for transmitting the parts to be marked from the feeding area to the processing area along a horizontal path, wherein the transmitting mechanism comprises two driving wheels and two driven wheels, which are pivoted to the device body and disposed on two opposite sides of the processing area and the feeding area, and two tracks separately wrapping outsides of each driving wheel and each driven wheel and following each driving wheel to rotate;
• a part blocking structure, disposed between the processing area and the feeding area and disposed over the transmitting mechanism, a height of the part blocking structure being greater than thicknesses of the multiple parts to be marked, and an interval greater than a thickness of one of the parts to be marked and less than thicknesses of two of the parts to be marked existing between the part blocking structure and the transmitting mechanism;
• and
• a first elevated blocking sheet module disposed among the two tracks, the processing area and the feeding area;
• wherein when the multiple parts to be marked are stacked on the transmitting mechanism in the feeding area, only the lowest one of the parts to be marked can be driven by the transmitting mechanism to move from the feeding area to the processing area via the interval along the horizontal path, and the rest of the multiple parts to be marked are blocked in the feeding area by the part blocking structure;
• wherein the part to be marked comprises two transverse part belts formed on two opposite sides thereof, and the two transverse part belts are placed on the two tracks;
• wherein the part blocking structure comprises two upright blocking plates fixed to the device body and disposed over the two tracks, the height is a height of each upright blocking plate, and the interval is formed between the two tracks and the two upright blocking plates;
• wherein the first elevated blocking sheet module comprises a first blocking sheet and a first actuator fixed to the device body and driving the first blocking sheet to be higher than or lower than the two tracks, and the first blocking sheet and the two upright blocking plates are located on the same horizontal plane or disposed on a side of the two upright blocking plates, which is adjacent to the feeding area.
