Corrugated plate, also known as profiled plate, is a product formed by machining plates into various waveforms. For other types of plates with the same thickness, the strength of corrugated plate can be increased by 10 to 30 times. Therefore, in many occasions with strict requirements on product weight, such as aerospace, ships, containers, truck compartments, highway isolation plates, etc., the use of corrugated plates has greatly increased. This naturally led to a sharp increase in the demand for corrugated plate welding and accelerated the process of corrugated plate welding automation.
Difficult problem of corrugated plate welding
1. Data acquisition challenges
For the current mechanical automation technology, there are many difficult aspects in the application of automatic welding, whether it is the collection of data or the technical optimization of mechanized manufacturing. Since automated data extraction technology can be said to be the key to achieving automation technology, data collection and collation should be the top priority.
2. Many variables affect welding quality during welding
In the process of construction, the implementation of automatic welding is still inseparable from the prototype of welding robots. For the current mechanized manufacturing industry, the design and production of large mechanized robots need to pay attention to many variables and are very complex. Many of them are human factors, including welding process selection, positioning, welding deformation treatment, etc. it is difficult to reduce these changing factors.
The laser displacement sensor independently developed by chuangxiang intelligent control, which contains high-speed signal processor and intelligent processing software, is the portable laser displacement sensor with integrated intelligent processing in the industry at present. Measurement principle: cylindrical objective lens is used to expand the laser beam into strips, the laser diffuses on the target, and the reflected light is imaged on CMOS. Displacement and shape are measured by detecting the change of position and shape. It supports 74 measurement modes to achieve various detection. It can be applied to 2D measurement, and can measure height, height difference, width, position, shape, section, warpage, flatness, angle, radius, shell thickness, etc; 3D measurement, solder bridge, volume detection, welding shape detection of laser tailor welded blanks, wood diameter measurement, etc.
The laser displacement sensor collects the weld position data in real time, and the industrial computer processes the data. The real-time position of the weld is fed back to the PLC, which can directly feed back the weld position. The positions scanned by the full wave are all real weld positions. It is equivalent to human eyes and brains. It can detect welds online and in real time 24 hours a day, driving the welding gun to accurately weld at the right position. It has the advantages of high precision, high cost performance, simple setting and convenient operation, and is suitable for integration into existing robots and automation systems.
