Abstract
The invention relates to a control system for a multi-wire cutting machine. A multi-wire cutting machine synchronous servo drive and constant tension control system includes an industrial personal computer, a main serve motor, a secondary serve motor and a take-up and pay-off serve motor. The invention is characterized in that the industrial personal computer sets a standard specified value which is sent to a main servo drive, at the same time, high-speed data transmission is carried out between the industrial personal computer and each servo drive via Profibus, the specified value and the data of the main drive are quickly sent to three secondary drive serve motors and the take-up and pay-off serve, the dependence on the synchronous character of each message is synchronously realized, the value synchronous with the main servo is calculated by the take-up and pay-off serve according to the above data and the diameter of the prior take-up reel and the line tension in the industrial personal computer, and the result is transferred to the take-up and pay-off serve via the Profibus bus.
Description
One, technical field:
The present invention relates to wire cutting machine, particularly its control system.
Two, background technology:
Multi-line cutting machine is to utilize the finer wire line of cut to cut hard and crisp machines such as monocrystalline silicon, cardinal principle is exactly to pass through complex mechanical construction frittering secant, shape by the silicon rod that cuts is woven into necessarily netted, and in whole gauze given invariable tension force, allow the running of line of cut net height speed then, spray the fine emery powder slurry on the net at line of cut at last, the workbench of feeding simultaneously drives the feeding of cutting gauze, finishes the cutting task.
The normal operation of gauze, need the high level of synchronization of a plurality of servomotors to guarantee, line of cut is put the line wheel of line of cut in operation process and the line wheel diameter of receipts line of cut constantly changes, keep the tension force of gauze constant, will constantly adjust the speed and the moment of torsion of actinobacillus wheel and take-up pulley, so require very strictness for automatic control and drive system, simultaneity factor also will have man-machine interface to operate and monitor, and also wants register system ruuning situation in the cutting process.So control system will have complex mathematical computations and logical operation capability fast, simultaneously the result of computing is passed to executing agency as soon as possible.And present wire cutting machine is difficult to reach this point.
Three, summary of the invention:
The objective of the invention is to overcome above-mentioned not enough problem, transmission of a kind of multi-line cutting machine synchronous servo and constant tension control system are provided, effectively synchronous servo and the control of permanent tension force are realized simultaneously, effectively enhance productivity and yield rate.
The technical scheme that the present invention is adopted for achieving the above object is: transmission of multi-line cutting machine synchronous servo and constant tension control system, comprise industrial computer and main servo motor, from servomotor and retractable cable servomotor, at first industrial computer is set a standard set-point, set-point is passed to the main servo motor, pass through the Profibus high speed data transfer simultaneously between industrial computer and each servo drive, the data of set-point and main servo motor are passed to 3 fast from servomotor and 3 retractable cable servomotors, synchronous realization relies on the synchronization character of each message, the retractable cable servomotor is according to above-mentioned data and when the front wheel diameter, line tension is calculated to the value with the main servo motor synchronous in industrial computer, result of calculation through the Profibus bus transfer to the retractable cable servomotor.
Described industrial computer passes through the given tension value of Profibus to the retractable cable servomotor, export to pneumatic control valve control tension arm through retractable cable servomotor interface, adjust angular speed and moment of torsion and realize that the retractable cable servomotor is by the constant linear velocity operation of setting, retractable cable line wheel diameter constantly changes, angular transducer measures the tension force of tension arm, actual tension and given tension force compare, and according to tension value and line wheel diameter computational speed, adjust take-up or payingoff speed.
When starting or stoping, receives by described retractable cable servomotor the data of set-point and main servo motor.
The present invention compared with similar products, effectively overcome existing can only the principal and subordinate servo synchronously, and can not the principal and subordinate servoly drive servo synchronous problem with line, adopt the high speed data transfer of Profibus communication, effectively solve the communication task between driver by high-speed serial bus and dispersion such as PC, PLC, the valve etc. as field level.Simultaneously Profibus also has Peer to Peer communication function, makes and can directly transmit data between the servo drive, need not pass through industrial computer or PLC, greatly improve servo between the synchronous speed of maintenance.Servo and the line of principal and subordinate drive servo between different data transfer modes, finally realize Synchronization Control, guarantee high yield, high efficiency.
Four, description of drawings:
Fig. 1 is network topology structure figure of the present invention.
Fig. 2 is a sync message structural representation of the present invention.
Fig. 3 is the tension force control flow chart.
Five, the specific embodiment:
As shown in Figure 1 transmission of multi-line cutting machine synchronous servo and constant tension control system, comprise industrial computer 1 and main servo motor 2, from servomotor 3 and retractable cable servomotor 4, pass through the Profibus high speed data transfer between industrial computer and each servo drive, at first industrial computer is set a standard set-point, set-point is passed to main servo motor 2, real data and state with set-point and main servo motor 2 passes to 3 fast from servomotor 3 and 3 retractable cable servomotors 4 simultaneously, synchronous realization hardware aspect industrial computer and servo design respectively have synchronizing function option plate, the software aspect relies on the synchronization character (as shown in Figure 2) of each message 6, the loyal message of each that transmit on bus all contains a synchronization character, guarantees to carry out simultaneously after receiving message same loyal content of message.Retractable cable servomotor 4 calculates in industrial computer according to above-mentioned data with when front wheel diameter and line tension, realize the linear velocity value consistent by in good time change magnitude of angular velocity with main servo, result of calculation to retractable cable servomotor 4, is adjusted to main servo motor 2 synchronous through the Profibus bus transfer.
When starting or stoping, receives by retractable cable servomotor 4 data of set-point and main servo motor 2, retractable cable servomotor 4 is because it takes turns shaft diameter constantly variation at work, therefore need in time to adjust angular speed and moment of torsion in the work, concrete adjusting process as shown in Figure 3, industrial computer passes through the given tension value of Profibus to retractable cable servomotor 4, export to pneumatic control valve control tension arm through retractable cable servomotor 4 interfaces, adjust angular speed and realize that retractable cable servomotor 4 is by the constant linear velocity operation of setting, retractable cable line wheel diameter constantly changes, angular transducer 5 measures the tension force of tension arm, actual tension and given tension force compare, according to tension value and line wheel diameter computational speed, adjust take-up or pay-out angle speed, reach constant linear velocity of whole gauze and tension force.
Provide one section concrete application code below so that the present invention to be described:
