Radial CTA Procedures and Adjustments

 

The following procedures provide setup and adjustment information for the

Component Transfer Assembly (CTA). In order to prevent interaction

between the adjustments, these procedures must be completed in the order

presented. Refer to the illustration for the special tools that are required to

perform the CTA setup and adjustment procedures.

Insertion Mount (IM) Safety Rules

 

The following rules are specific to IM equipment (also known as Through

Hole) :

• Whenever powering the IM machine down for maintenance, follow

the next two procedures:

• On the AC power panel, push the breakers to the OFF

position. Also, at the AC power panel, turn the key to the

OFF position and remove.

• Attach a warning notice to the AC power panel showing the

machine is not operational and only the maintenance

technician is authorized to restore power.

• Disable the Full Command function to prevent machine operation

from a Host controller or UCT. This must be done if a maintenance

procedure requires machine power.

• Only qualified maintenance technicians are to use the Interlock

Bypass key switch to bypass the IM safety interlock circuits.

 • Interlock Bypass: Never leave the Interlock Bypass key in the On

position except during maintenance. During non-maintenance

operations, the key switch must be in the Off Remove position with

the key removed to a secure area.

Head Drive Home Pulse Setup Procedure

The following procedure explains how to set up the head drive home pulse
with respect to the vertical and theta axes and the limit position.
Prerequisites:
Timing belts are removed
Tools:
MTR Home Pulse Setup Fixture
Comments:
This procedure is only used when setting the machine up at the factory or
when replacing the timing belt or motor in the field. Timing belts are to be
inspected on an annual basis.
This process is written for the use of both the manufacturing factory (place of
origin) technician performing the adjustment on the bench and the field
technician performing the adjustment at the customer's site.
The goal of this procedure is to position the head vertical at its negative limit
and the head theta at a point between its positive and negative limit
establishing the optima home pulse location, relevant to these limits.
Failure to properly perform this setup results in the machine not zeroing
properly.

Procedure:

1.Power down the machine and perform Lockout/Tagout according to local procedures.

 

2.Insert the setup fixture so it positions the head to the negative vertical
limit, and the head theta between its positive and negative limit.

 

3.Loosen the 4 motor mounting bolts and slide the motor up against the
tension spring. Hold it in position and retighten two of the bolts.

4.Slip the belt off the pulleys. Rotate the head theta motor shaft so that
the mark on the top of the shaft lines up with cables exiting the motor
housing, then rotate the shaft clockwise approximately 20 degrees
further.
5.Attach the belt to the pulleys while holding the motor shaft in
position.
6.Loosen the head theta motor mounting screws to allow the tension
spring to slide the motor into position. Retighten the motor mounting
screws.
7.Loosen the head vertical motor mounting screws and slide the motor up
against the tension spring using the jacking screw.

 

 

8.Rotate the head vertical motor shaft so the mark (or keyway, if no mark
exists) on top of the shaft lines up between case mounted connectors of
motor housing.
9.Attach the belt to the pulley while holding the motor shaft in position.
10.Loosen the head vertical motor mounting screws to allow tension
spring to slide the motor into position. Retighten the motor mounting
screws .
11.Remove the setup tool.

Removal and Disassembly of the Head Drive Assembly

Prerequisites:
Drawing of the Radial Insertion Head Assembly
Electrical Wires Disconnected
Insertion Head Tooling has been removed
Comments:
This procedure assumes that the head drive assembly is being disassembled
to replace the drive mechanism.
To rebuild this assembly, reference the reassembly procedure found in this
module.
If possible, it is more efficient to remove the motors and bearings from the
assembly with the casting secured to the machine.
Procedure:


1.Power down the machine and perform Lockout/Tagout according to
local procedures.

 

 

2.Use a clamp to secure the head drive assembly, and remove the 4
mounting bolts. Lift the head drive assembly from the machine.

 

          

 

3.To replace the drive mechanism, first loosen the socket head cap screw
and remove the threaded locking collar clamp from the top of the drive
mechanism shaft. This allows the separation of the bearing assembly
from the top of the drive mechanism.

 

 

4.Loosen the screw in the push rod clamp and unscrew the push rod. This
allows the bearing assembly to completely separate from the drive
mechanism.

BEC Board Setup for VCD/JW

Purpose:
This procedure adjusts the BEC board settings so the positioning system
performs the correct adjustments to board error conditions encountered
during production runs.  If these settings are not correct, incorrect
adjustments would cause component misinsertions.
Prerequisites:
Rotary Disk Squareness Adjustment
Clinch To Head Alignment
Special Tools:
Card Extender (43682901)
Adjustment Procedure:
 

Wear a wrist strap connected to ground to prevent electrostatic
discharge from causing damage to boards.
 

1.Power down the machine as described in the Operation manual.

2.Disconnect the edge connector from the BEC board in I/O slot 11.
3.Remove the BEC board from slot 11 of the I/O box.
4.Insert the card extender in I/O box slot 11.
5.Insert the BEC board into the card extender.
6.Connect the edge connector to the BEC board.
7.Cover the BEC sensor with an opaque object.
8.Power up the machine as described in the Operation manual.
9.Activate the IM Diagnostics  as follows.  Refer to the IM-UPS and IM
Diagnostics documentation for specific details relating to the operation
of the machine terminal.
Select the IM Diagnostics icon.  

WARNING
When the machine is in the IM Diagnostics function power is provided to
the machine.  Exercise caution when performing the following
procedures to avoid Injury to personnel and equipment.
 

10.After the IM Diagnostics has completed its initialization, select  the
following.  
 

Machine Setup>Board Error Correction
The Setup Board Error Correction screen is displayed. 

12.While watching the X axis A/D Counts indicator, adjust otentiometer R82 to achieve a display of 0.
13.While watching the Y axis A/D Countsindicator, adjust potentiometer R81 to achieve a display of 0.
14.Power down the machine as described in the Operation manual.                        
 

15.Remove the BEC board from the card extender, then remove the card
extender from I/O box slot 11.
 

16.Insert the BEC board into I/O box slot 11 and connect the edge
connector to the BEC board.
 

17.Remove the opaque object from the BEC sensor.
 

End of procedure.

Component Transfer Assembly Procedures 52788501 Rev. –
7. Manually hold the latch open in order to avoid contact with the leads
on the setup tool. Extend the CTA component transfer to the head.
Set-up Tool
8. With the CTA extended to the insertion head tooling and the set-uptool in the guide jaw, check the alignment of the grooves in the bottom
guide to the leads on the set-up-tool. The leads should be seated in the
bottom of the "V" slots. If they are, there is no need for further
adjustment. If not go to the next step.
