Abstract
The present invention relates to a piece pasting machine control system based on a CAN bus, which adopts a distributed structure. The control function of a piece pasting machine is divided into a field module connected with a PC by a CAN bus; the PC is inserted with an image card and a CAN bus adaptation card; various components, such as a piece pasting machine X-Y movement platform driving motor, a piece pasting head driving motor, etc., are respectively connected with respective CAN control modules and connected with the CAN bus adaptation card by the CAN bus. The bus structure of the present invention largely reduces connecting lines and enhances reliability, and the system is easy to expand and modify. The present invention is favorable to realizing network and strengthening interference immunity.
Description
Technical field:
The present invention relates to a kind of control system of chip mounting machine, belong to mechanical control field based on the CAN bus.
Background technology:
Developing rapidly of information industry and electronics industry, the big good market of having facilitated microelectronics production equipment, wherein chip mounter is a kind of a large amount of wide product.Because chip mounter needs high-speed, high precision and high reliability running, so its control system is had very high requirement.The control system of chip mounter all is to adopt traditional upper and lower computer structure at present, host computer is based on PC (industrial computer), mainly finish upper strata work such as man-machine interaction, trajectory planning and Vision information processing, video camera is used for the site error of correcting element, image card is inserted in the PC ISA slot, is connected by video line between video camera and the image card.Slave computer is inserted in the ISA slot of PC based on the motion control card (as PMAC) of special use, mainly finishes motion control and input/output signal and handles.Be connected by 40 core cables between chip mounter X-Y motion platform drive motors and the slave computer, be connected by the multichannel stube cable between placement head drive motors and the slave computer, Chip (sheet) element and IC (integrated circuit) chip material loading air valve, PCB (printed circuit) plate material loading location clamps air valve and chip mounter motion detection vacuum valve, and is connected by multiway cable between the slave computer.Because chip mounter is a complex device of being made up of a lot of functional units, need the motor of control to have 10-14, all kinds of input and output (I/O) signal reaches 100-200, comprise mainly that wherein pcb board material loading, location, pinched valve I/O reach 20, Chip element and IC chip material loading valve reach 100-120, placement head motion detection and vacuum valve I/O reach 20, and motor and I/O are distributed in each position of chip mounter simultaneously, and lower floor's controlled function all concentrates on the motion control card.Mainly there is following problem in such control system structure:
1, because all kinds of motors, comprise that the optical encoder on the motor and the hundreds of bar line of numerous I/O mouth all are to focus on the motion control card, therefore cause the wiring position crowded, anti-interference is poor, reliability decrease.
2, line is many and mix, and causes material, installation and maintenance cost height.
3, lower floor's Control Software is too concentrated, and autgmentability is poor.
Summary of the invention:
The objective of the invention is to problem, a kind of new control system of chip mounting machine based on the CAN bus is provided, make the controlled function of chip mounter resolve into field module, to significantly reduce the line number at present centralized control system of chip mounting machine existence.
For realizing such purpose, in the technical scheme of the present invention, adopt distributed frame, the controlled function of chip mounter is resolved into field module, link to each other with PC by the CAN bus.PC is finished upper strata work such as man-machine interaction, trajectory planning and Vision information processing, be used for the video camera of correcting element site error, be connected with image card in being inserted in PC ISA slot by video line, the CAN bus adapter is inserted in the PC ISA slot, and PC is linked to each other with the CAN bus.On the CAN bus, connect polylith CAN control module, clamp air valve and chip mounter motion detection vacuum valve etc. by multicore cable with chip mounter X-Y motion platform drive motors, placement head drive motors, Chip element and IC chip material loading air valve, pcb board material loading location respectively and link to each other.CAN bus adapter and each control module interconnect with twisted-pair feeder, have therefore significantly reduced wiring.
Adopt after the CAN bus, the whole system operation process is:
PC carries out motion planning by the upper strata algorithm, the result that generates differed to the local motion controller of placement head by the CAN bus transfer mend processing, realization is to the extracting of chip, utilize gamma camera to proofread and correct the pose parameter of institute's grab chips, these data arrive the X-Y platform driver by the CAN bus transfer, internal drive is solidified algorithm and is gone out the corresponding compensation value by these data computation, the distributed processing mode of this information real-time Transmission has guaranteed the movement high-precision and control real-time of chip mounter, because a large amount of minimizings of aerial lug, the reliability of system also improve greatly.
The present invention with real-time CAN bussing technique, has formed new control system of chip mounting machine with advanced person's fieldbus notion, compares with traditional control system of chip mounting machine, and main effect has:
A) adopt bus structures, control module can be placed in the place that actuator interface is concentrated respectively, has significantly reduced line, has improved reliability;
B) after line reduces greatly, material, installation and maintenance cost have been reduced;
C) lower floor's Control Software can be distributed in each control module, and system is easy to expansion and revises;
D) because each control module cost is low, can carry out the redundancy design, increase fault-tolerance;
E) help realizing networking that the CAN standard itself is exactly based on network structure, can construct various topological structures such as point-to-point, multi-multipoint easily;
F) anti-interference strengthens, and can adopt the CAN controller chip that has special electromagnetic compatibility, and system's anti-electromagnetic interference capability is improved.
