Optical Manufacturing Solutions 2 Probe Assembly Dismount Dismount Turn off main power and air. Remove probe cover. Unhook power connection to sensors.
Optical Manufacturing Solutions 3 Probe Assembly Dismount Disconnect all airlines that go to the probe assembly (X,V, AS, R, & T). (The first two steps will require cutting some zip ties.) Remove two screws from the left side which hold the probe assembly in place. (There are also two dowel pins that support the probe assembly.) This should allow you to remove the probe assembly from the machine.
Optical Manufacturing Solutions 7 Probe Assembly Mounting Remounting of Probe Assembly Start with installing the two screws that hold the probe assembly to the machine. Start each screw and tighten each little by little to make sure both are going in evenly. There are also two dowel pins to help this process.
Optical Manufacturing Solutions 9 Probe Assembly Mounting Connect all 5 airlines (X, V, AS, R, & T) “X” – This connects to the X fittings on the probe assembly that feed the two small air cylinders. They function to open the probe arms. “V” – This connects to the V fittings on the probe assembly that feed the two small air cylinders. They function to close the probe arms. “AS” – This connects to the AS fitting. It is for the pneumatic system air flow. This feeds air to the air bearings and the locks on the probe assembly. “R” – This connects to the fitting at the top of the large air cylinder. This pushes the cylinder out, causing the probe assembly to be lowered. There is an adjustable restrictor near the fitting. “T” – This connection is on the bottom of the large air cylinder on the probe assembly. This pushes the cylinder to the up position, raising the probe assembly. Again, there is a restrictor to adjust speed of the cylinder.
Optical Manufacturing Solutions 12 Probe Assembly Mounting Connect the sensor power for the probe assembly.
Optical Manufacturing Solutions 13 Probe Assembly Mounting Dress airlines and cables using zip ties (do NOT tie them to the probe restrictors). See photo to know how to dress these items. Do NOT pull zip ties completely tight.
Optical Manufacturing Solutions 14 Probe Assembly Mounting 1.Reconnect air and power to the machine. 2.With air connected and turned on, double check that the probe arms can move up and down freely. In addition, check that the rotation at the magnet is ok and not catching. 3.Double check that all probe sensors are working correctly. 4.Check and set probe assembly timing via the diagnostics screen (see p. 16 of this document). 5.Probe Tip Settings Secure probe tips using screws; for the top most probe tip, the screw goes into the tip from above, through the metal arm. For the bottom most probe tip, the screw goes into it from underneath the probe tip. (American standard screws) Tighten side screws. Make sure tip flat is away from you when mounted into the unit. Set probe tip spacing -This space should be very close (preferably 0.20 to 0.30). -On the inside of the probe assembly, attached to the probe arm bearings, there is a screw and lock nut. -Screw the bottom screw all the way in and lock it into poison using Loctite. Adjust the top screw and nut for spacing between the two new probe tips. Probe tips should be new and unused when doing this adjustment. After adjustment, be certain that the two plastic probe tips do NOT overlap vertically. (see photo on next p.)
Optical Manufacturing Solutions 16 Probe Assembly Mandatory Adjustments/Calibrations needed after installing a new probe assembly After physically installing the new probe assembly and connecting all airlines and electrical connector: Go to the "Timing" tab on the Diagnostics Screen" Put a check mark in the check box in the Probe section of the screen. Touch the "Start Timing Test" button on the screen. Use the adjustable restrictors on the probe assembly to get the four timing numbers for the probe assembly near the middle of their respective ranges. *PLEASE NOTE: The restrictors for closing the probe tips together should be adjusted so that the lower probe tip closes slightly faster than the upper one. Airlines to the probe assembly are labeled: X = open probe tips V = closing probe tips T = raising the whole probe assembly
Optical Manufacturing Solutions 17 Probe Assembly After probe motion timing is set correctly as described on the previous page, do the following: 1. Navigate to the ES-curve calibration screen. 2. Press the "Install New Probe" button and then follow the prompts on the screen.
Optical Manufacturing Solutions 18 Probe Assembly With the top of the Spindle Cover tilted towards you and the bottom of the Spindle Cover below the end of the spindle, slide the cover towards the back of the unit until the spindle shaft is aligned with the circular opening in the bottom of the Spindle Cover. Once aligned, raise the Spindle Cover up and push the top back until it attaches with the Left and Right Hand Z-Axis Rear Plates. Install six M3 x 8 knurled head thumb screws (35-053-480) and six O-rings (90-051-384), three on each side of the Spindle Cover.
Optical Manufacturing Solutions 19 Probe Assembly Once the Spindle Cover is attached to the side mounting plates, wrap the Gnarly Cable Wrap around the flange on the top of the Spindle Cover. Finally, after the cover is installed and secured, use the Diagnostic Screen (Probe Tab) to verify that the “Probes Raised” sensor is checked when the probe assembly is raised and inside the cover.
