Toshiba Industrial Robot TH180

Cautions on Maintenance and Inspection

When performing inspection or maintenance of the robot,; strictly observe the following precautions to protect; yourself; and coworkers.

• Be sure to turn off the main power switch of the controller; before approaching the robot for maintenance and; inspection.

2.2 Layout of Robot Components and Drive Mechanism

The layout of the robot mechanical components is shown in; Fig. 2.1 and Fig. 2.2.

The drive mechanism of each axis is described below.

Lubricated state of ball screw spline

Make sure that the ball screw spline (or tool shaft) is greased; completely and that no rust is developed on it.;

Fill grease to the ball screw spline.

Lubrication of reduction gears

Fill grease to the reduction gears from the grease nipples.

Make sure that all cables and air tubes are in the good; state.

Replacement of position detector batteries

(Be sure to replace the batteries every year.)

Replace the position detector backup batteries (housed in; the; robot base unit). If the running time is long, battery; consumption is small. If the power OFF time is long, the; consumption is large. If the battery voltage drops, a battery; alarm occurs. Then replace the batteries immediately.;

Inspect the flexible cables, reduction gears, ball screw; splines, timing belts and motors, then replace them when; necessary.

(Replace the battery every five (5) years.)

Replace the RAM (controller) backup battery. If the running; time is long, battery consumption is small. If the power OFF

time is long, the consumption is large. If the battery voltage; drops, the battery alarm message saying “1–145 MAIN

Battery alarm” is displayed. Then replace the battery; immediately.

Replacement of switching power

supply unit (Replace the battery every five (5) years.)

Apply the grease to the ball screw spline.

Move each axis by hand and make sure that it moves; smoothly.

(1) Make sure that each timing belt is not worn off or; cracked.

(2) Check each timing belt for tension.;
