Description of drawings
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.
Fig. 1 is the structure principle chart of the rotary positioning mechanism of turntable type fusing machine;
Fig. 2 be turntable type fusing machine rotary positioning mechanism electrical schematic diagram.
Embodiment
Referring to accompanying drawing 1, the rotary positioning mechanism of the utility model turntable type fusing machine mainly comprises the servo-drive system that is made of servo-driver, PLC microprocessor and servomotor.
Utilize the position control function of PLC microprocessor, the judgement of data operation, data processing and the logical relation of process PLC microprocessor internal, the running status of detection servo-drive system, controlling the potential energy (servo ON) of servo-drive system, send certain umber of pulse according to certain frequency to servo-driver by high speed output, thereby realized acceleration and deceleration, travelling speed and the anglec of rotation of rotating disk.Simultaneously servo-drive system itself is again a closed-loop control system: servo-driver is sent the frequency of pulse and travelling speed and the rotational angle that quantity controls servomotor here according to the PLC microprocessor, and servomotor is given servo-driver by its subsidiary rotary encoder with motor actual motion speed and rotational angle again and constituted a closed-loop system.
Application process of the present utility model: referring to accompanying drawing 2, after the energising, the PLC microprocessor is in init state, searches for the signal of each sensor, the state of detection servo-drive system; When the drive operation that detects servo-drive system just often, the PLC microprocessor is opened servo potential energy, is made servo-drive system produce rotor that excitation is decided by delivery outlet 104, whether the matrix of the pressurization of PLC microprocessor inspection simultaneously rises is put in place, whether this plate of safety is in normal position etc., when all rotating conditions satisfy, press operation button machine and begin to carry out the zero-bit search, rotary body begins to rotate, search for zero-bit, in case servo-drive system is stopped immediately and electrical null position and mechanical zero are united after detecting zero signal with setting speed; Finish make zero after, the PLC microprocessor is good with the umber of pulse calculation process of speed, acceleration and every rotation one less important transmission of rotation; PLC microprocessor search is from the signal of each check point, in case when satisfying rotating condition, the PLC microprocessor sends the umber of pulse of rotation one less important transmission immediately with the good acceleration of computing, speed to servo-driver; Whether the PLC microprocessor begins to detect machinery and is rotated in place after pulse transmission is finished, and just waits for when not putting in place, and matrix begins decline to the PLC microprocessor, carry out bonding and cooling with regard to starting upward in case mechanical movement puts in place; The PLC microprocessor carries out bonding and Cooling Control according to process data, after the PLC microprocessor finishes bonding and Cooling Control, has promptly finished the work of a beat; After the PLC microprocessor has been finished the work of a beat, the startup command of next work tempo such as begin.
1) former point search
The matrix that is checked through pressurization when the PLC microprocessor rises and all rotating conditions such as to put, whether this plate of safety is in the normal position in place when all satisfying, press operation button machine and begin to carry out the zero-bit search, rotary body with setting speed begin to rotate, the search zero-bit; In case servo-drive system is stopped immediately and electrical null position and mechanical zero is united after detecting zero signal.
2) data processing
If there be n station (working position) in one week of rotating disk bonder, be about to a week 360 ° of n five equilibriums, that is: rotating disk of the every work of servo-drive system is with regard to 360 °/n of rotating machinery angle, but before servo motor, connected m reductor doubly, therefore servomotor of the every work of servo-drive system need rotate m*360 °/n, the driver of servo-drive system is set for k pulse/commentaries on classics, and the every work of servo-drive system once just needs the PLC microprocessor to send a k*m*360 °/n pulse to the driver of servo-drive system so; Weight and inertia according to machinery carries out the processing of acceleration and speed simultaneously, the frequency control that sends pulse is good, and the transmission pulsed frequency has just determined the travelling speed of servomotor, acceleration and the retarded velocity that transmission pulsed frequency acceleration and deceleration slope has just determined the servomotor operation.
3) speed control
The machine rotation once promptly forwards next station to from a station, the needed time is depended on the travelling speed of servo-drive system, come the transmission frequency of control position pulse by the PLC microprocessor, " 00000 " high speed output by the PLC microprocessor is given the servo-drive system driver with pulse transmission, servo-driver is with the failure message of servo-drive system simultaneously, the information that puts in place of servo motor passes to the PLC microprocessor by 14 and No. 15 pin of connector CN5 respectively, these two signals just enter the PLC microprocessor from 1.0 and 1.1 terminals of the input port of PLC microprocessor respectively, when PLC microprocessor judges during to the servo-drive system fault, the PLC microprocessor sends " operation is forbidden " signal from 106 of delivery outlet to servo-drive system; Equally, when the PLC microprocessor judges when servo motor operation puts in place, the PLC microprocessor sends " data zero clearing " order by 105 of delivery outlet to servo-drive system error is carried out zero clearing, has so just avoided the accumulated error of system.Thereby realized speed control to servo-drive system.On hardware, select the servo-drive system of the TSB08751C-2NT3 model of TECO Electro Devices Co., Ltd. for use, comprised the control of acceleration, retarded velocity and maximal rate in the speed control of servo-drive system.
4) high-speed pulse output
The position ring control of this servo-drive system requires an impulse source to be arranged, require the frequency of pulse transmission higher.Select for use the PLC microprocessor of the CP1H-40DT model of Japan OMRON to realize centralized control as requested, this PLC microprocessor is transistor output, it has the high-speed pulse delivery outlet that frequency reaches 1M, owing in the system of PLC microprocessor is provided with, set " direction+pulse " control mode, therefore " 00000 " and " 00002 " of circuit mouth carries out pulse output, put the rotation side that servomotor is being controlled in the pulse of " 00000 " mouth, and the sense of rotation of servomotor is being controlled in the pulse of " 00002 ".
5) position ring of servo-drive system control
Owing to adopted the position ring control of servo-drive system, the servo motor scrambler flows to servomotor drive with position signalling from connector CN1 mouth through shielding line, and the PLC microprocessor carries out data operation and handles, sends corresponding pulse for the driver of servo-drive system by the high-speed pulse delivery outlet; The servo-drive system of closed loop own detects physical location, carries out positioning after location positioning is controlled, is rotated in place then by the scrambler on the servo motor.
