The function of all kinds of JUKI Control Board

Page view

Each control board control realizes the use function of JUKI miracle, what is the function of each control board card? Here are the answers:

A. CPU board: function can be seen as a simplified computer, and other substrates of the I/F through the CPCI socket, interface bridge substrate, VME interface to connect;

B. XMP substrate: the XMP substrate acts together with the RMB (JGRMB substrate and the JHRMB substrate). It is the control substrate of the servo motor and the stepping motor, and the XMP substrate can control up to 19 axis motors:

a.  Output the serial instruction signal of 16bit from the RMB substrate, control the XY axis, the ac servo motor of the ZQ axis:

XY axis: using the rotating converter of the motor to control the speed counting electromagnetic ruler to control the positioning; ZQ axis: using the rotating converter of the motor to control the position;

b.  Output pulse instruction from RMB substrate, control central motor, backup motor, automatic width adjusting motor step motor;

c.  Detect the opening of the emergency switch, immediately stop the XY axis, ZQ axis;

d.  Monitor the origin of each axis and limit the sensor;

e.  Servo start, electromagnetic ruler alarm detection;

f.  Equipped with XY shaft, ZQ shaft and backup motor R axis position management counter;

C. SYNONET connection substrate: SYNONET connection substrate is JGRMB substrate, safety substrate, carry connection substrate and motor drivers, electromagnetic ruler, limit the signal connection substrate between sensors:

Signal to transfer zy4 axis driver and XMP substrate, in which alarm Signal is output from insulated image probe to SAFETY substrate;

Signal to transfer electromagnetic scale and XMP substrate;

Signal to limit XY axis;

Output to offset JGRMB substrate and SAFETY substrate;

Signal to transfer center motor, backup motor, auto width adjustment motor driver and XMP substrate (via carry substrate);

D. Interface bridge substrate: connected with CPCI interface and VME interface, is the substrate accessed from CPCI to VME:

CPCI interface connected substrate: CPU substrate, XMP substrate;

 VME interface connected substrate;


E. MCM substrate: this substrate is the control and calculation substrate of sensor (NMLA or FMLA) used in the center of the component;

F. SAFETY substrate:

Detect emergency switch, limit sensor, X-SLOW sensor, block servo power supply;

Detect passport switch, X-SLO sensor, notify XMP substrate;

Transfer sensor, solenoid valve, ATC sensor, solenoid valve signal operation through carry transfer substrate I circuit;

Install SMEMA I/F circuit;

Save M/S parameter FLASHROM;

G. A carrier substrate: the substrate is mainly a signal of a transfer sensor;

H. Base-feeder substrate: this substrate is equipped with feeder propulsion, temperature sensor and vacuum transmission, signal lamp control, MTC I/F and other functions:

LED1:CPU works normally;


LED3: system is FAIL;

If fails, 2, 3 lights;

I. I/O substrate: transmits 16bit long serial data, and the device substrate controls the cpu:68000 12MHZ of the substrate (except the head main substrate):

LED1: fail;

LED2: HALT  d;

LED3: normal action;

J. Mount the head main substrate: communicate with the main control computer by transmitting the serial I/F, which is the I/O substrate to control the head.

Actuation of solenoid valves for vacuum and flow;

Reading of vacuum data monitored by vacuum sensors;

Reading of ON/OFF of bad markers conveying chamber receptors and determination results;

Deceleration sensors for detecting Z-axis;

K. Operating the substrate: install each switch to start, stop, etc.; inform the safety substrate of the open state and the servo status of the shield switch, and the state of the emergency switch; carry out the transfer of the control signal;

L. Light ctrl substrate: this substrate carries on each kind of lighting of the VCS device on the base and the light adjustment of the OCC lighting of the mounting head, the driving lighting conversion cylinder of the standard VCS camera and the optional high resolution camera;

M. IP-X3 substrate: this substrate is the image substrate that processes the image data of the substrate mark, IC mark, IC chip, etc. taken by the OC, VCS camera, and calculates the position correction of the substrate, and the value of the part position correction.
