A microcontroller (1) is connected with a signal transmitting device, a driver (2) and a sensor (3). The output of the driver (2) is connected with a stepping motor (4). An output shaft of the stepping motor (4) is connected with a positioning turntable (5) and a crucible (6). A sensor (7) positioned at a side of the positioning turntable (5) is fixedly connected with a shell or a rack of the stepping motor.
Description
Technical field:
The utility model is relevant with film coating apparatus, and is especially relevant with the crucible control device.
Background technology:
Existing crucible control device drives crucible by the crucible transmission mechanism again and rotates as all directly driving rly. control motor with PLC as most of units such as U.S. TELEMARK company, German Lai Bao company, Korea S K-MARC companies.Control is directly to be finished by PLC, and a cover PLC program can only be formulated at the crucible of a certain type, and must regroup the PLC program when changing the crucible type more likely needs to increase the PLC expansion module, does not have versatility and PLC costs an arm and a leg.
The utility model content:
The purpose of this utility model provides a kind of with low cost, highly versatile, digital crucible controller applied widely.
The utility model is achieved in that
The utility model microcontroller 1 is connected with signal transmitting apparatus, driving mechanism 2 and transmitter 3, the output of driving mechanism 2 is connected with stepper-motor 4, the output shaft of stepper-motor 4 is connected with crucible 6 with location rotating disk 5, and transmitter 3 is positioned at the side of locating rotating disk 5 and stepper-motor housing or frame and is connected.
Said signal transmitting apparatus is one or more in charactron and keyboard managing chip 8, manual operation button 9, serial ports 10 switch signal generators 11 and the switch signal receptor 12.
The utility model is simple in structure, accurate positioning, suitable dissimilar crucible, and highly versatile has a plurality of signal transmitting apparatus can supply to select for use, and is easy to use, applied widely.When switching the crucible type, do not need hardware is done any change, the parameter that only needs to revise crucible by serial ports or operating panel gets final product.
Description of drawings:
Fig. 1 is the utility model block diagram.
Fig. 2 is the working sensor schematic diagram.
Fig. 3 is sensor fixing structure figure.
Embodiment:
The crucible controller mainly comprises: microcontroller 1, driving mechanism 2, serial ports 10, education department's machine 13, stepper-motor 4, keyboard, indicating meter, switch signal take place and receptor.
Microcontroller: adopt the PIC18F452 micro-chip as control chip, whether step-by-step impulse transmission, serial communication, the detection plated film relevant device of being responsible for stepper-motor have the switch signal input, return reaction crucible state of switch signal, detecting sensor signal, communicate by letter with keyboard managing chip ZLG7290 with charactron;
Indicating meter and keyboard: indicating meter and keyboard portion adopt the ZLG7290 charactron to show and the keyboard scan managing chip, can manage 8 cloudy charactron (or 64 independent LED) and 64 buttons altogether simultaneously, should be with making it manage 6 charactrons, 12 LED and 5 buttons simultaneously.Adopt I between ZLG7290 and the PIC18F452
2C communication, RA0 control ZLG7290 resets.RB2 is disconnected as down trigger, and when RB2 detected negative edge, PIC18F452 began to receive the information that ZLG7290 transmits.RC3 is SCL, and RC4 is SDA;
Driving mechanism: driving mechanism 2 adopts Q3HB64MA three-phase hybrid stepping motor driving mechanism as driving stepper-motor.PIC18F452 passes through to send to driving mechanism the level of step-by-step impulse and control driving mechanism direction control mouth, can rotate and sense of rotation by the control step motor.The direction control end of the output data latch 74HC373 that the RA3 work is connected with driving mechanism, RD0-RD7 is as data bus.RD0-RD7 cooperates with RA3 step-by-step impulse and direction control signal is sent into driving mechanism, can the control step motor;
Transmitter: adopt direct-injection type infrared switch ST135 as feeler mechanism.When with the co-axial location of stepper-motor rotating disk 5 on narrow when meeting by ST135, output terminal on the ST135 can produce a level saltus step, microcontroller 1 is read this saltus step (RB2, RB3 read the ST135 of crucible 1, crucible 2 respectively) by RB2, RB3, just can eliminate error, the correction position of crucible in rotation process according to the variation crucible controller of ST135 level.
The switch signal receptor: adopt the input data switch, RA1 cooperates data bus RD0-RD7 and RC2, RC5 to read in switch signal as input data switch 74HC244 direction control end, and rotates according to the signal control crucible;
Switch signal generator: adopt output data latch 74HC373, RA2 cooperates data bus RD0-RD7 and RC0, RC1 outputs level signals to drive the Darlington driving mechanism as output data latch direction control end, by Darlington driver drives rly., produce switch signal by rly. and reflect the crucible state;
Manual operation button: RE0, RE1 connect 2 toggle switch, are used for selecting whether to select manual operation.RB4-RB7 connects 4 buttons, is used for manually controlling the rotation of crucible;
Serial ports: adopt the RS485 agreement, RA4 is as the direction control end, and RC6, RC7 are as the sending and receiving end.Be used for communicating, be convenient to by the computer control crucible with computer 13.
