Welding robot application technology is a fusion of robot technology , welding technology and system engineering technology. Whether welding robot can be applied in actual production and exert its superiority depends on the common improvement of these technologies, and system engineering technology is robot technology. And welding technology adhesives. At present, the welding process is becoming the mainstream process in industrial production at an alarming development speed, and the welding quality and welding productivity are problems that no enterprise can ignore, and thus the wide application of welding robots is imperative. In the past, due to the lack of professional and technical talents in China, the application of robots lacked in-depth development and utilization, which made its utilization efficiency far from being well reflected. Today, this situation is changing rapidly.
Robot characteristics
Flexible
The robot is a CNC stereoscopic machine tool with six degrees of freedom, which not only achieves the accessibility of the torch position, but also achieves the angle change of the torch. Although its accuracy cannot be compared with conventional machine tools, for the welding production, the repeatability of the robot has been completed.
From a business perspective, the balance of purchase and output of equipment is very important for enterprises, and with the influence of the market, the renewal cycle of products is relatively shortened. If a welding machine is used for welding production, it is difficult for the welding machine to quickly adapt to changes in the product when the product is changed, which hinders the launch speed of the new product. This delay is likely to seriously affect the rapid development of the enterprise. With robots for welding production, companies only need to develop a new program to start production of new products, which will enable enterprises to seize the opportunity in the market.
2. Human-machine dialogue
Human-machine dialogue means an increase in automation, but it also brings us efficiency and efficiency. Human-machine dialogue is the exchange of "instructions" and "sensing", and its development depends on the development of sensing technology. At present, more and more sensors have been used on the welding robot workstation. For example, the current detection device can be used to track the welding process; the visual sensor can be used to detect the weld position.
3. Application characteristics in China
(1) The application of welding robots in China is mainly concentrated in the industries of automobiles, motorcycles, construction machinery, railway locomotives and so on. Automobiles are the largest users of welding robots and the earliest users. Welding robots in automobile manufacturing and auto parts manufacturing companies account for 76% of all welding robots. In the automotive industry, the ratio of spot welding robots to arc welding robots is 3:2, while other industries are mostly arc welding robots.
(2) Since the 1990s, the introduction of advanced technology, production equipment and process equipment has enabled China's automobile manufacturing level to increase its speed to large-scale production, and foreign welding robots have entered China in large numbers.
(3) China's welding equipment level, manufacturing level and system integration capability of front and rear process equipment still have a large gap with foreign countries, which directly restricts the development of robots in other domestic industries.
(4) Everyone's understanding of robots is far from enough. Some people demand too much for it. One-sidedly, it can be welded regardless of the product. The good or bad use of robots represents the manufacturing level of a company. Therefore, companies must improve their manufacturing level to meet the production requirements of robotic welding.
Fast Ethernet Switch is 10/100Mbps adaptive fast Ethernet Optical Media Converter, with 10M/100Mbps self-adaptive switch, converting the independent 10Base-T or 100Base-TX twisted pair electrical signal with 100Base-FX optical signal. It extends the network transmission range from 100m, the limit of copper line, to 120Km (single mode full duplex). It supports two different types of network connection media, 10/100Base-TX and 100Base-FX. By switching technique and storage & forwarding technique, it realizes the data transmission between two network connection media. It supports optical transmission under dual-fiber multi-mode, dual-fiber single mode, and single fiber single mode.
