Sheet metal fabrication processing is formed by laser cutting or stamping process, shear and bending, bending, bending, welding, riveting. The Sheet metal fabrication used are cold-rolled plate (SPCC), hot-rolled plate, galvanized plate (SHCC) (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum (5052), stainless steel. Sheet metal fabrication processing steps: according to the parts drawing (3D) expanded into a plan (2D), laser cutting or die stamping shape, CNC punching each bending part, should pay attention to the direction of the burr of the workpiece. Then the students are welded or riveted (some). Surface treatment after processing: electroplating, passivation, sand blasting (powder), anode treatment. Products are generally made for the connection and the outer cover. Applications in robotics, drone, communications, medical devices, industrial automation equipment.

In the cold winter, adjusting the brightness of the street lights does not have to go outdoors, sitting in the monitoring center can do it; in large shopping malls, parking lots, smart phones can tell you where the toilet is, where the car is parked, and how to install navigation through the LED lighting system. Can do it. Yesterday, the Smart Lights Cross-Strait Cold Semiconductor Lighting Technology Forum held by this Winter Expo was widely discussed around the topics of cold semiconductor semiconductor technology research and development hotspots and latest achievements. The forum is jointly sponsored by the National Semiconductor Lighting Engineering R&D and Industry Alliance, the Provincial Science and Technology Department, and the Municipal Government.
LEDs turn on the era of intelligent lighting. Just as the replacement of horse-drawn carriages made a qualitative leap in the traditional transportation industry, semiconductor lighting has become a successful technological revolution as an environmentally-friendly and energy-saving lighting source. Wu Ling, secretary-general of China Semiconductor Lighting Engineering R&D and Industry Alliance and chairman of the World Semiconductor Industry Alliance, said that LED semiconductor lighting has gone far beyond the stage of seeing and seeing, and it is not only an environmental protection function for energy conservation and emission reduction. The era of intelligent, controllable and digital lighting will be opened, especially the combination of semiconductor lighting and biological science, which will make life safer, more comfortable and healthier.
According to the Harbin Science and Technology Bureau, at present, the city applies 150,000 LED lamps in the fields of ice and snow landscape, road lighting, indoor lighting, etc., with a total investment of nearly 200 million yuan, achieving the effective integration of ice and snow culture and art, characteristic architectural art and semiconductor lighting. To create a dream of the city of Dream Ice City and Bright River City. It is reported that after Beijing and Shanghai, the city established the third semiconductor testing center in the country, laying a foundation for the intelligentization of lighting equipment.
Intelligent street lights can remotely control which street lights are dim, and there will always be enthusiastic citizens calling to tell the electric department. In Taiwan, there is no need to bother the public. The street lamp management unit can receive a warning at the first time through a unified monitoring center. The computer immediately reports the cause of the malfunction and can realize remote control. Ai Zuhua, technical director of Delta Group's Zhongda Dentsu (Shanghai) Co., Ltd., said that two years ago, most of the street lamps in Taiwan had installed intelligent positioning and navigation systems, and sent signals to the background server of the monitoring center in real time, enabling remote monitoring. Monitoring data collection of street lamp working status, brightness adjustment, carbon dioxide emission, etc., can also carry out remote maintenance operations to truly realize the urban smart grid.
Fan Qingwei, director of the Harbin Lighting Inspection Center, believes that if this technology is applied to a cold city like Harbin, it will not only find damaged street lamps and equipment in the first time, but also save manpower and material costs and achieve unattended operation.
LED lights can still see the smart phone shake, you can immediately find the same partner who shakes your phone. The positioning of LED indoor lighting is similar to that of shaking. You only need to stand under a certain light, and the shops, toilets and parking lots in your vicinity will be clearly displayed through the smart phone.
Guo Cheng, director of the National Key Laboratory of Semiconductor Lighting Innovation, said that traditional wireless navigation technology can only solve the problem of outdoor positioning, but it is a layman for indoor positioning, and wireless signals are affected by multiple factors. The LED positioning technology only needs to install the positioning system in the lighting fixture. The user of the handheld smartphone only needs to download the professional software to accurately locate the position within two meters. LED lighting positioning systems will be everywhere, as long as you are illuminated by the lights, you can also locate the ads, you can also provide advertising push services for nearby shops. Intelligent positioning systems increase the added value of lighting products, turn lighting products into services, and generate sustained profits for the enterprise. Guo Cheng said.
According to industry insiders, LED intelligence can replace the sky to help the police arrest criminals. It can also be widely used in medical, banking, commercial and other fields, and will bring a new lighting revolution.
