High precision jet dispensing machine adopts the DSP advanced digital signal processing technology, can effectively improve the working efficiency of the jet dispensing machine, work faster and more efficient operation, and through the PC end is connected with different demand of the programming work, support the use of spray path design of PLC, but also support direct import of CAD engineering drawing work. Have a direct teaching function, can quickly perform various irregular spraying work path, but also through the manual teaching work for the parameter adjustment, flexible mode of operation can effectively improve the quality and efficiency of spraying work. The jet dispensing machine has a very high anti-interference ability, which can avoid the electromagnetic interference of the outside to affect the normal working quality, and has a more practical effect in precision production. The use of Dsp in the dispensing work is very wide, can be applied to irregular seam glue filling work, ensure the filling quality and practicability, high precision spraying quality greatly enhance the jet dispensing machine, can be equipped with a complete support high-speed spray work in jet dispensing machine assembly line work, to help users achieve the dispensing work more efficient and comprehensive.
