Description

Technical Field

[0001] The present application relates to the field of 3D printing, and in particular to an integrated laser module and a laser engraving machine using the same. Background Art

[0002] With the development of semiconductor laser technology, the user demand for consumer-grade semiconductor laser engraving machines is increasing, but some problems have also emerged. Many of these machines are not equipped with a fire extinguishing function, but when engraving and cutting flammable materials, it is very common for the material to catch fire. At this time, the fire source continues to spread on the material and is likely to cause a fire, resulting in a safety accident. Therefore, the fire extinguishing function is very urgent.

[0003] The fire extinguishing function of the laser engraving machine currently on the market can be roughly divided into gas fire extinguishing and liquid fire extinguishing according to the fire extinguishing medium. The gas fire extinguishing method is to extinguish the fire by releasing the high-pressure fire extinguishing gas in the gas tank, but the disadvantage of the gas fire extinguishing method is that the fire extinguishing is mostly used once, and the user cannot add gas by himself, and needs to purchase a new fire extinguishing device. Liquid fire extinguishing is to spray liquid on the material to quickly cool the material, while isolating the oxygen on the surface of the material, and immersing it inside the material to reduce the temperature of the material so that the material is below the ignition point, thereby achieving the purpose of extinguishing the fire. Water is usually used as the medium for liquid fire extinguishing. Liquid fire extinguishing requires an independent spraying system, including a storage liquid container, a liquid extraction device, a delivery pipeline, and a spraying device. The existing liquid fire extinguishing is generally independent inside the machine, not highly integrated with the machine as a whole, without monitoring and feedback devices, basically fixed-point large-format indiscriminate spraying, and no fixed-point spraying function.

[0099] Those skilled in the art will understand that "connection" is mainly used to refer to the inanimate connection (physical) between objects, including the meanings of being connected and associated, and refers to a direct or indirect physical matching relationship between multiple entity components.

[0100] Those skilled in the art can understand that "connectivity" mainly refers to the fact that between at least two imaginary parts (such as cavities, holes, grooves, etc., which are spaces with transmission capabilities defined by solid components) and / or real parts containing the imaginary parts, the imaginary parts have a communicating spatial matching relationship.

[0101] It can be understood that the integrated laser module 10 of the present application and the laser engraving machine 1 using the same, the integrated laser module 10 integrates flame detection function, water-gas integrated fire extinguishing function and basic laser engraving and printing function. Specifically, the focusing component 13 is integrated with a sensor 135 capable of detecting flames, integrating the flame detection function into the integrated laser module 10, and realizing dynamic sensing of the flame based on the movement of the integrated laser module 10; the water-gas integrated pipe 121 and the water-gas integrated joint 122 of the water-gas integrated transmission component 12 can cooperate with the connecting part 111 of the heat dissipation component 11, so that the gas is connected to the focusing module via the water-gas integrated pipe 121, the water-gas integrated joint 122 and the airway 1110, and the gas introduction is integrated; at the same time, the water-gas integrated pipe 121, the water-gas integrated joint 122 and the liquid transmission pipe group 123 of the water-gas integrated transmission component 12 are used to realize the integration of liquid introduction, and the precise extinguishing of the flame is realized based on the movement of the integrated laser module 10.

[0102] In one embodiment, the heat dissipation component 11 further includes a plurality of heat dissipation blades 112 . The plurality of heat dissipation blades 112 are arranged at intervals and connected to the connection portion 111 . The plurality of heat dissipation blades 112 are arranged around the focusing component 13 .

[0103] It can be understood that the multiple heat dissipation blades 112 are arranged on the same side of the connecting portion 111 facing the focusing assembly 13, and the multiple heat dissipation blades 112 are respectively provided with openings of different sizes. The multiple openings correspond to each other layer by layer to form a accommodating cavity that can accommodate the focusing assembly 13. One end of the focusing assembly 13 is connected to the connecting portion 111 and is arranged in the accommodating cavity and surrounded by the multiple heat dissipation blades 112.

[0104] In one embodiment, the spray pipe group 1233 is disposed through the plurality of heat dissipation blades 112 and has a plurality of nozzles 12333. The plurality of nozzles 12333 are respectively disposed between the plurality of heat dissipation blades 112 at intervals, and the plurality of nozzles 12333 are all disposed toward the end of the focusing assembly 13.

[0105] It can be understood that the plurality of heat dissipation blades 112 can fix and position the spray pipe group 1233 and carry the spray pipe group 1233. The spray pipe group 1233 is provided with a plurality of nozzles 12333 to spray liquid for fire extinguishing or cooling. The plurality of nozzles 12333 are correspondingly arranged between the plurality of heat dissipation blades 112, that is, each nozzle 12333 can be exposed through the gap between two adjacent heat dissipation blades 112, so that the nozzle 12333 can be arranged toward the end of the focusing assembly 13.

Multiple sensors 135 are arranged in a roughly ring-shaped manner in sequence to match the structure of the output end 132 and the gas nozzle 134. Multiple sensors 135 arranged around the output end 132 are more sensitive and more accurate in sensing the area pointed by the output end 132, which is convenient for improving the sensing precision and accuracy. At the same time, the sensor 135 is arranged at the output end 132 to realize full monitoring and closed-loop control from discovering the fire to extinguishing the fire.

[0109] It can be understood that the sensor 135 provided in the present application communicates with the control component 15 through wiring (not shown) or wireless communication to achieve signal interaction. The specific interaction method can select a known and feasible solution, and the specific parameters and structure are not repeated here. The sensor 135 provided in the present application can at least be used to detect flames.

The air guide pipe 1112 is connected to the middle part of the air guide hole 1111, and the air guide pipe 1112 connects the air guide hole 1111 with the air inlet 133, so that the airway 1110 is connected to the adapter cavity 1225 and the air inlet 133.

[0111] Further integration Figure 7 and Figure 8 As shown, in one embodiment, the water-gas integrated tube 121 includes a first tube wall 1211, a second tube wall 1212, and a first connecting structure 1213. The first tube wall 1211 is spaced outside the second tube wall 1212, and the first connecting structure 1213 connects the first tube wall 1211 and the second tube wall 1212.

[0112] In this embodiment, the first tube wall 1211 and the second tube wall 1212 are both roughly hollow cylindrical, the cross-sectional diameter of the first tube wall 1211 is larger than the cross-sectional diameter of the second tube wall 1212, and the first tube wall 1211 is sleeved on the outside of the second tube wall 1212 to form a gas transmission cavity 1214 and a liquid transmission cavity 1215 spaced apart from each other, so that the water-gas integrated tube 121 can integrate the transmission of gas and liquid. The first connecting structure 1213 is located between the first tube wall 1211 and the second tube wall 1212, and is used to connect the first tube wall 1211 and the second tube wall 1212 so that the two remain integrated.

By driving the integrated laser module 10 to move, targeted and efficient fire extinguishing can be achieved.

In addition, after the material fire is extinguished, the gas pump 191 can be closed with a delay to discharge the remaining water in the water-gas integrated pipe 121, so as to avoid the water being stored in the water-gas integrated transmission component 12 for a long time and reduce the risk of storage leakage.
