Description

Technical Field

[0001] The utility model relates to optical detection equipment, in particular to a HUD detection machine. Background Art

[0002] HUD is the head-up display technology for automobiles. Its function is to allow drivers to view the driving information of the vehicle in real time without lowering their heads, bringing a better driving experience and improving the safety of vehicle driving. With the development of vehicle manufacturing technology, more and more automobile products use HUD technology, especially HUD has become a standard technology in new energy vehicles. The existing HUD detection usually customizes the corresponding detection system and test bench for a specified type of automobile glass, which can only detect HUD glass products of the corresponding model, and different models cannot be interchanged. However, the distinctive car styling of different brands and models and the HUD technology that has not yet been standardized correspond to a wide variety of HUD glass products. This requires manufacturers to customize a set of detection equipment for each HUD glass that needs to be tested, and customize detection equipment one by one for hundreds of varieties. This is undoubtedly a huge initial investment. Customizing special HUD detection systems and equipment one by one has brought a huge burden to HUD glass manufacturers. The storage and management of hundreds of sets of HUD detection equipment is also a big problem. Manufacturers need to plan special equipment storage warehouses and provide specialized technicians to manage, maintain and debug these equipment. It consumes a lot of manpower and material resources, occupies a lot of space resources, and increases the production cost of the enterprise. Once the product specifications are switched, the corresponding HUD detection system and equipment must also be replaced. Each time the system and equipment are replaced, the equipment needs to be re-debugged and the system parameters need to be recalibrated. The process is cumbersome, time-consuming and labor-intensive, which seriously affects the production efficiency of the production line. The existing HUD detection system and equipment still use offline detection solutions, which cannot be connected to the glass production line, cannot realize online automatic detection, and have low detection efficiency. In response to the above problems, the industry has proposed some general-purpose HUD detection equipment, such as a utility model patent with application number CN202023189773.9 and the name of a general-purpose HUD optical detection device. Although this type of equipment enhances the versatility of the detection device, it still has the disadvantages of slow glass clamping efficiency and weak clamping stability in actual application.
