Description

Technical Field

[0001] The invention relates to the technical field of three-dimensional laser detection control, and is a three-dimensional laser cutting machine optical path adjustment detection device and method. Background Art

[0002] The sheet metal covering parts of automobile parts include hood, trunk, radiator frame, bumper, fender, door, as well as chassis parts such as beam, control arm, rear axle, etc., which often require three-dimensional cutting, including trimming and punching.

[0003] Applicable scope of materials. Applicable to stainless steel, carbon steel, alloy steel, silicon steel, galvanized steel plate, nickel-titanium alloy, chromium-nickel-inconel alloy, aluminum, aluminum alloy, titanium alloy, copper and other metal materials. Widely used in various manufacturing industries such as aerospace, automobile and shipbuilding, machinery manufacturing, elevator manufacturing, advertising production, household appliance manufacturing, medical equipment, hardware, decoration, metal external processing services, etc.

[0004] 3D laser cutting machines are widely used in various manufacturing industries such as aerospace, automobile and shipbuilding, machinery manufacturing, elevator manufacturing, advertising production, home appliance manufacturing, medical equipment, hardware, decoration, and metal external processing services.

[0005] Safety, comfort, energy saving and environmental protection have always been the themes of the development of the world's automobile industry. As one of the main processing methods in modern automobile production, the development of laser technology is mainly centered around this theme and combined with the characteristics of this profession. The automobile industry is one of the fields with the most laser processing applications. According to relevant statistics, 50%-70% of the parts in industrialized countries in Europe and the United States are completed by laser processing. In 1998, there were more than 3,000 laser processing machines used in the automobile industry worldwide, and hundreds of laser processing machines are put into use every year. There are also thousands of low-power lasers used in detection and rapid prototyping in the automobile industry.

[0006] Laser welding equipment for automobile body-in-white roof This equipment is used for automobile body-in-white roof welding equipment, which consists of two robots, a fiber laser, a wire feeder, a welding head, a laser protection room and a floor fixture. During work, a robot with a laser welding head is used for welding. The top cover fixture is carried by the robot and positioned through 4 V-shaped positioning blocks and the positioning support frames on both sides. The 4 clamping cylinders on the positioning support frame clamp the top cover fixture. The top cover fixture and the robot contain a quick-change device that can switch between multiple models of tooling. Unlike the traditional spot welding process, laser welding can achieve molecular bonding between two steel plates. In layman's terms, the hardness of the steel plate after welding is equivalent to that of a whole steel plate, thereby increasing the strength of the body by 30%. The bonding accuracy of the body is also greatly improved. On the other hand, the overlap width and some strengthening components can be reduced, and the volume of the body structure itself can be compressed, thereby reducing the weight of the body.

[0007] Since laser is an invisible light source, multiple dot tests are required during the optical path adjustment of the 3D laser cutting machine. The number of steps during debugging increases, the variables are too large, the accuracy is low, and the work efficiency is reduced. It is very dangerous for personnel to directly contact the laser nozzle, which can easily cause personal injury.

[0008] With the continuous development of social industry, human beings have an increasing demand for processing quality, and 3D laser cutting is being used more and more widely. Its field is automobile body design and manufacturing. There will be a large number of 3D laser cutting equipment installed and debugged for production and later maintenance. Because laser is an invisible light source, in the process of adjusting the optical path of the 3D laser cutting machine, it is necessary to repeatedly perform laser dotting for testing. The testing process not only increases the consumption of materials and working hours, but also has too many variables and low accuracy, and can only rely on years of experience to debug. At the same time, it is very dangerous for personnel to directly contact the laser nozzle, which can easily cause personal injury. Therefore, it is necessary to develop a 3D laser cutting machine optical path adjustment and detection method to solve the key technical problems of 3D laser cutting laser optical path adjustment and detection, and provide strong support for the installation, commissioning and later maintenance and detection of 3D laser cutting equipment.

[0009] Compared with the prior art, the present invention can improve the coaxiality of the optical path and the laser head of the three-dimensional laser cutting machine during cutting in different postures, detect the quality of the light spot, reduce repetitive operations, improve work efficiency and avoid personal injury caused by direct contact of human hands with the laser nozzle.
