[Abstract]:Optical glass is an important material for making the key parts of optical instruments. The weight of optical glass is directly related to the thickness, curvature and radius of optical lenses, which affect the quality of optical instruments. With the continuous improvement of production efficiency, manual weighing separation begins to meet the demand of production, and studies a high precision and high speed automatic. Weighing and sorting technology has become an urgent need. Therefore, this paper has carried out the technical research of automatic weighing and sorting machine for optical glass block.
In this paper, the system scheme of the separator is formulated, including the two parts of the mechanical system and the measurement and control system. The differential weighing principle is selected and the zero drift phenomenon can be effectively controlled and the high precision measurement can be realized.
The structural design and assembly of the mechanical system of the separator are completed, including the feeding mechanism, the weighing mechanism and the grouping mechanism. The upper and lower feeding mechanisms are based on the belt transmission, and the weighing mechanism and the grouping mechanism are based on the pneumatic technology.
The hardware system is composed of three parts: action program control, measurement system and I/O interface. The action program controls the mechanical action through PLC; the measurement system completes the acquisition and processing of the weighing signal; the I/O interface realizes the communication between the PLC and the industrial control machine, the PLC controls the sampling of the industrial control computer and the working process. The control machine notifications PLC group results. The industrial control computer software is based on the LabVIEW development, and gives the friendly man-machine interface which is adapted to the field results display, debugging operation, fault alarm and so on.
The use of the separator shows that the measuring precision of the system is + 0.02g, the working rhythm is less than 2s/, the grouping is accurate, the desired design goal is achieved, the automatic sorting of high precision, high efficiency and low breakage rate can be realized, and the requirement of automatic weighing and sorting of optical glass block can be met.
