2, level of integrated system is not high.Each printing cell of circular screen printer has the independent position servo controlling card in the background technology, promptly has what printing cells just to have how many piece position servo control cards, and this is for the beyond doubt individual huge system of many chromatographys (more than 8 chromatographys) circular screen printer; From the angle of electromagnetic compatibility, this has also reduced the interference free performance of system.
3, system design cost height.Circular screen printer in the background technology is because each printing cell has the independent position servo controlling card, so the hardware cost of the required cost of system design will increase along with the increase of printing cell number.
Summary of the invention
The purpose of this utility model provides a kind of circular screen printer to flower unit central control device, and it is suitable for extensive circular screen printer system, and level of integrated system height, system design cost are low.
The technical solution of the utility model is, design a kind of circular screen printer to flower unit central control device, it comprises main control unit 1, main order electromotor scrambler 2, conduction band main order electromotor control executing mechanism 3, industrial computer 4, the shaft position servo control unit, the first cylinder motor control unit 8, the second cylinder motor control unit 9, N cylinder motor control unit 10, main order electromotor scrambler 2, conduction band main order electromotor control executing mechanism 3, industrial computer 4 is electrically connected with main control unit 1 respectively, it is characterized in that: main control unit 1 is electrically connected with shaft position servo control unit 15 by control bus 12, shaft position servo control unit 15 is by the unit controls bus 11 and the first shaft position servo control unit 5, the second shaft position servo control unit 6, N shaft position servo control unit 7 is electrically connected, and simultaneously by a plurality of cylinder motor control units of unit controls bus 11 controls.
Described shaft position servo control unit 15 comprises digital signal processor DSP 13 and programmable logic device (PLD) FPGA 14 at least, and digital signal processor DSP 13 is electrically connected with programmable logic device (PLD) FPGA 14.
The utlity model has following advantage:
1, is suitable for the circular screen printer system of any scale.The utility model is the action of controlling a plurality of (can reach 24 at most) cylinder motor with a position servo control card, solved the not enough problem of bus slot mentioned in the background technology, is suitable for the circular screen printer system of any scale.
2, level of integrated system height.The utility model is only used the action of a position servo control card with regard to may command a plurality of (can reach 24 at most) cylinder motor; The utility model has dwindled the volume of circular screen printer control system, and the use and the circuit that have reduced resolution element greatly are interconnected, the level of integrated system height.
3, the system design cost is low.The utility model has reduced the use number of the position servo control card with identical overall dimensions and same design scheme, has saved hardware resource, has reduced the system design cost.
4, simple in structure, reliable.The utility model has adopted the bus printed circuit board arrangement, it with multiaxis position servo control card between adopt connector to connect, simple in structure, reliable.
