In the present invention, by touch screen operation unit software configuration, arranged by the transposition algorithm in PLC program and transposition, workpiece Spin parameters and export control instruction to executing agency and servo-drive system.Touch-screen hardware selection be OMRON company NS12-TS00B-ECV2, PLC adopt be OMRON company CP1H-X40DT1-D.
As shown in Figure 2, the configuration software that the picture of touch-screen can use it to support on computers makes, and is called and required picture is designed in the setting of continuous item by the instrument of software tool archive.In the present invention, touch screen operation unit mainly contains five interfaces according to processes situation such as control turntable part type and station selection etc.: main interface (window 1), 18 station factory interface (window 2), 6 station factory interface (window 3), 3 station factory interface (window 4), blade parts factory interface.Each interface comprises numerical value output, state display, windows exchange button and control button.According to the control planning of control system, Fig. 2 gives the distribution map at each interface.
Connection between touch-screen and PLC as shown in Figure 6,
Data transmission is carried out by RS232 serial ports, PT-PLC stube cable model: XW2Z-200T, 9 pins, 2m between touch-screen and PLC.Serial communication option template number: CP1N-CIF01.
Software design patterns is arranged serial ports A in touch-screen software: serial ports (S)-PLC, Hostname-SERIALA, type-SYSMAC.PLC, agreement-NTLink (1:N), communication speed-at a high speed, NTLink (1:N) unit number-0.Define serial ports 1 in PLC programming software: communication setting selection-definite value, its baud rate is 115200, and pattern is that NTLink (1:N), NT/PC connection is 1 to the maximum.
Spraying turntable spraying process is as follows:
After washing test part, be installed part start plasma spraying equipment, writes robot movement and control spray gun running orbit;
Start transposition turntable, system energization, by station flow path switch adjustment transposition turret stations, spray gun and initial processing work position are aligned;
Workpiece rotation, sprays workpiece;
After having sprayed, restart spraying rotating platform control system, control station by station flow path switch and be transformed into next workpiece station;
Go to workpiece rotation, carry out spraying process to workpiece, circulation is carried out, until complete whole workpiece, and last censorship.
As shown in Figure 3, step is as follows for station flow path switch:
System electrification, reads control information and relevant parameter;
Start servo-drive system, select transposition turntable rotation mode;
According to the rotation mode selecting to determine, calculate umber of pulse by station transfer algorithm and export servo-drive system to, controlling the angle that station often walks rotation;
Once replace.
Station transfer algorithm is:
Wherein, Pn is the umber of pulse that servomotor rotates one week correspondence, and i is turntable and servo motor transmission ratio, and G is station number.
The control mode that each station adopts in transpose process is position control, and the number that PLC exports pulse determines the angle that servomotor rotates.In the present embodiment, Pn008 is the setting of electronic gear integer, and setting value is that motor revolves the command pulse number turned around.In this control system, Pn008 settings are 1000, and namely PLC exports 1000 pulses, and servomotor rotates a circle.In this apparatus design process, frame for movement determines turntable with servo motor transmission than 1:200, and namely servomotor rotation 200 circle turntables revolve and turn around.For 18 stations, between station and station, be 20 °, pulse number that PLC sends is N, Pn is servo-driver Pn008 setting value, its intermediate value is 1000, can calculate thus, during 18 station, N=11111; During 6 station, N=33333; During 3 station, N=66666.
In station transfer process, adopt position control mode, the number exporting pulse determines the angle that servomotor rotates.The frequency exporting pulse determines transposition speed.The frequency height transposition time is short, and the frequency low transposition time is long.For 18 stations, the technological requirement transposition time is 3 ~ 4s, and setting pulse output frequencies is 2000Hz.In order to solve, transpose process suddenly opens, anxious its pulse of stall platform inertia problems of too acceleration frequency is 500Hz, and pulse deceleration frequency is 500Hz.
Station rotation adopts speed control method, and its servomotor rotary speed is relevant with the size of input analog amount, and its relation as shown in Figure 4.When input voltage is 10V, servomotor rotating speed is 5000r/min.
Starting for solving rotation process, stopping inertia problems of too need set deceleration time soft start acceleration time, soft start, as shown in Figure 5.Acceleration time is set as 290ms, and deceleration time is 350ms.
Following accompanying drawing is touch screen interface figure, is respectively main interface, 18 station factory interface, 6 station factory interface, 3 station factory interface and blade parts factory interface.Touch screen interface figure, as shown in Fig. 7 ~ 12, is respectively main interface, 18 station factory interface, 6 station factory interface, 3 station factory interface and blade parts factory interface and station conversion device interface.
Operation interface function:
(1) system energization/power operation button: only after system energization, servo-drive system could normally work, otherwise revolving table position can not rotate.
(2) workpiece rotation/stall action button: when workpiece is in spraying process, according to technological requirement, it needs 360 ° the corresponding operating such as to horizontally rotate.
(3) station switching button: after the part of a station has sprayed, when needing to spray next station part, makes it carry out station conversion operations.
(4) forwards/reverse fine setting action button: after Burners Positions is fixing, part initial position and Burners Positions not necessarily align completely, need to carry out small adjustment.
(5) servo ann reset button: after servo-drive system hardware or software break down, reporting to the police appears in servo-drive system, and trouble light is bright, does not now allow to carry out any operation, after pending fault is got rid of, clicks servo ann reset button, just can carry out subsequent operation.
(6) return to the homepage button: pressing this button system meeting main interface of auto-returned, then carry out related interfaces selection, spraying dissimilar part for selecting.
(7) interface has Presentation Function, has report to the police instruction, workpiece of servo to rotate instruction, function such as station conversion instruction, servo operation instruction etc., while can show current processing stations number, the station number allowing operating personnel grasp at any time to have processed.
(8) by online simulation or off-line simulation, after determining that compiled engineering data is correct, just it can be downloaded in touch-screen.The file that rear click is preserved, compiling can generate an XOB type finished by software.Just associative operation can be carried out by touch-screen in this file download to touch-screen.
During operation, first, system power supply is connected, touch-screen enters main interface, according to type and the quantity selection factory interface below of processing parts, as tooling pin axial workpiece 6, namely in main interface, select bearing pin class station apparatus, then press 6 station select buttons, enter into 6 station factory interface.Press system energization button, servo-drive system is energized, and according to the deviation of spray gun and initial manufacture position, by forwards/reverse trim button, adjusts initial manufacture zero-bit.Then, establishment spray gun operation sequence, after spray gun operation program is finished, presses station rotary button, starts spray gun and carries out spraying operation.After current part has sprayed, press station switching button, turntable rotates to next station, then carries out spray gun and sprays the second station part, now the display 1 of processing stations counting, and representative has processed a station.Reciprocal successively, until finally complete the spraying operation of 6 parts, now processing stations counting display 6.In this external process, the situations such as servo, workpiece rotation, station conversion can be monitored at any time, all have corresponding indicator lamp alert.
