Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting robots, and particularly relates to a laser cutting robot that can effectively reduce flue gas emissions. Background Technique

[0002] Laser cutting uses a highly focused high-power density laser beam to irradiate a workpiece, causing the irradiated material to quickly melt, vaporize, ablate, or reach the ignition point. At the same time, a high-speed gas flow coaxial with the beam is used to blow away the molten material, thereby realizing the cutting of the workpiece. As an important tool in modern manufacturing, laser cutting robots have the characteristics of high precision, high efficiency, and flexibility, and play an important role in various fields; with the continuous innovation of technology and the continuous expansion of the market, laser cutting robots will play an increasingly important role in future industrial production.

[0003] After patent retrieval, a Chinese patent with the publication number CN213196161U provides a laser processing robot with high cutting efficiency. Through the coordinated use of a workbench, a laser cutting robot, a first support column, a second support column, a top plate, a filter box, a first connecting pipe, a negative pressure fan, a hose, a second connecting pipe, a suction head, a first cylinder, a fixed seat, a fixed clamping plate, a long groove, a second cylinder, and a movable clamping plate, it can effectively solve the problem that the flue gas generated during the cutting production process of traditional laser processing robots is easy to pollute the environment. This device can conveniently collect the flue gas, filter it and then discharge it, and a filter layer is arranged in the filter box, which is composed of activated carbon adsorption particles, and can effectively adsorb and filter harmful substances in the flue gas, reduce the pollution caused by the emission of flue gas, and achieve the purpose of purifying the air.

[0004] The suction head used above is kept at a relatively far distance from the cutting position of the workpiece, and this distance is usually not adjustable, resulting in the flue gas being easily overflowed from the side during the cutting process, making it difficult to be effectively captured and processed, thus affecting the cleanliness of the working environment and the health and safety of operators. In addition, after long-term use, the filter layer gradually becomes blocked due to the difficulty of convenient replacement, reducing the filtering efficiency and practicality of the equipment and increasing the maintenance cost. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a laser cutting robot that can effectively reduce flue gas emissions, which can improve the effect of flue gas treatment, effectively ensure the cleanliness of the working environment and the health and safety of operators, and further improve the filtering efficiency and practicality of the equipment and reduce the maintenance cost.
