Automatic Loading & Unloading Device Research Of Low-E Glass Production Line

Low emissivity coated glass is also known as Low-E glass.With the continuous introduction of national energy conservation and environmental protection policies,the Low-E production line has developed rapidly in China in recent years.There are mainly two forms of production line,one is the online Low-E,and the other is the offline Low-E.At present,the latter is mostly used in the domestic market.Our company has developed a series of matching production equipment according to current market needs,among which automatic loading & unloading device is an indispensable important equipment for the production line.Among the existing common equipment for glass stacking,only the industrial robot can achieve the function of loading & unloading,and can also grab from the lower surface of glass plate,but it can not grab glass plates with large-size or heavy-weight.The price is relatively high,especially when using large quantities robots,it is unreasonable to calculate from the perspective of economic operating costs,so it is necessary to design and develop an alternative product.The fully automatic loading & unloading device can meet the process requirements of off-line Low-E production line.Main research contents and achievements of this paper are as follows:1.Determine main technical parameters for automatic loading & unloading device through process analysis of Low-E production line.Design horizontal walking mechanism for main components,analyze its working principle and structural characteristics,and make detailed selection calculation analysis of the main components.2.Design the turnover mechanism of automatic loading & unloading device,analyze its structural features and working principles according to the design task,and analyze main components.The three-dimensional modeling of turnover mechanism is carried out by Solid Works software,and the simulation plug-in is used to statically analyze the strength and deflection displacement of its overall structure to verify whether it meets the design requirements.Through dynamic analysis by Solid Works motion plug-in,the movement trajectory of big arm is simulated,load problems of the arm at different stages during the motion are analyzed,the required torque is calculated,and the appropriate driver is selected based on the torque size.Based on the data measured in the experiment,the factors affecting the operating cycle of loading &unloading are analyzed.Verify whether the design requirements are met.3.According to the working principle of vacuum system,firstly design vacuum control system,including the calculation on selection of vacuum sucker,vacuum generator and vacuum switch electromagnetic valve,and finally check the entire vacuum system.4.This paper also introduces electrical control principle of automatic loading &unloading device,and designs electrical control principle for loading and unloading of the device respectively.Detailed design of electrical control system includes parameter design of operating panel and touch screen.Finally,through the actual inspection of factory,those designs meet the process requirements,and achieve the design purpose.
