Precautions When Designing End-effectors
Design an end-effector to meet the requirements described below. Otherwise, a robot failure may result.
If the end-effector design precautions are not observed, the clamped parts of the robot unit may become loose, rattle or be out of position, possibly damaging the robot unit and robot controller.
For Y axis and Z axis, which has a small static allowable moment, an excessive force applied to the end-effector may damage the slider. If the robot comes in contact with an interfering object, a pressing force due to the motor is applied, possibly damaging it. Pay utmost attention to these possibilities when designing end-effectors.
Maximum Payload
Design the end-effector so that the total mass of the end-effector including a workpiece will be less than the maximum payload capacity of the robot. The total mass includes the wiring, piping, etc. connected to the robot unit and their stays.
| Robot type | LZNN | LZZN | LYZN | LYZZ |
|---|---|---|---|---|
| Maximum payload | 5 kg/Z *1 | |||
| Robot type | LSNN | LSSN | LZSN | LZSS |
|---|---|---|---|---|
| Maximum payload | 3 kg/S (2kg/S when S axis is 400 mm) *1 | |||
*1 Check the range of the center of gravity with "Allowable range for the center of gravity of the payload (PDF:251KB)". If the center of gravity locates outside of the allowable range, reduce the weight.
