Technical Field
The utility model relates to the technical field of laser engraving machines, in particular to a porous air tap of a laser engraving machine.
Background
In the working process of the window lens of the laser module, dust particles generated by high-temperature burning of the laser are easy to adsorb, so that the window lens is dirty, and laser cannot be effectively transmitted out from the window lens. On the one hand, the effective power of the laser module is reduced. On the other hand, the laser energy absorbed by the window lens is increased, the temperature of the lens is increased, and the lens is easy to crack under the action of high temperature.
In order to protect the window lens from dust particles, it is common practice to introduce compressed air in front of the window lens to form a clean air layer to isolate the dust particles from the window lens.
This requires the design of a proper gas path structure, and the compressed gas can complete the complete path of 'leading-in- & gtcirculating- & gtleading-out' under the condition of no leakage of gas.
The air tap and the adapter commonly used for the current laser module adopt a single Kong Fangshi therebetween, and the mode needs the central axis of the compressed air outlet hole of the adapter and the central axis of the compressed air inlet hole of the air tap to ensure that the air quantity of the air path is maximum in the same axial direction, thereby effectively protecting the window lens. However, this approach has the following problems: 1) The installation and matching are difficult, and once the central axis of the compressed air outlet hole of the adapter block is not matched with the central axis of the compressed air inlet hole of the air nozzle, the air path is blocked with high probability; 2) The cost is high, the workers are required to have higher thread processing and coordination skills, the positions of the central axis of the compressed gas outlet hole of the adapter block and the central axis of the compressed gas inlet hole of the air tap are accurately judged in advance, then the threads of the adapter block, the outlet hole, the threads of the air tap and the inlet hole are processed, and the processing mode has higher cost; 3) The reject ratio is high, and this mode needs to guarantee simultaneously between adapter piece and the air cock, and screw thread matching and hole axis match, and processing technology requirement is high, in case there is the screw thread mismatch, perhaps the axis mismatch, leads to the product bad or scrapping easily.
