Core Function and Structure Analysis of OTC Daihen Collision Sensor SSV (Shock Sensor)
In the OTC DAIHEN industrial welding robot system, the Collision Sensor (Shock Sensor, model series usually SSV or SSB) is commonly known as the “anti-collision box”. It is the core safety hub installed between the robot’s sixth axis (J6 flange) and the welding torch body.
In complex automated arc welding working conditions, accidental physical interference between the welding torch and the workpiece or fixtures is highly prone to occur. The collision sensor integrates a highly sensitive spring return mechanism and a micro-switch signal loop internally. Once the welding torch suffers an abnormal external impact from any direction (X, Y, Z), the SSV sensor will instantaneously undergo physical deflection, cutting off the internal safety signal (triggering the A5016 alarm), forcing the robot’s servo motors to execute an emergency braking stop within milliseconds. This greatly protects the expensive robot body reducer and the welding torch barrel from devastating damage. Below is the original parts exploded view and official model reference for the SSV type sensor:

Collision Sensor (SSV) Workshop Frontline Maintenance and Impact Troubleshooting Core Standards:
- Aging and leakage hidden danger of O-ring (3574-017): The O-ring inside the sensor not only plays a role in mechanical buffering but, more importantly, it seals the gas chamber for the welding shielding gas. Due to long-term exposure to high-temperature arc radiation, the O-ring is prone to hardening and carbonization cracking. Once damaged, shielding gas will leak massively inside the sensor, resulting in weak gas flow reaching the contact tip, triggering dense gas pores in the weld seam. It is recommended to perform a soap water leak check every half year and periodically replace the original O-ring.
- Physical reset after a severe collision: When the robot collides and pops up the
A5016 (Collision Action)alarm, it is strictly prohibited to immediately force an alarm reset and continue operation. Operators must enter the teach area, manually shake the lower part of the collision sensor gently, and check whether the internal spring returns smoothly and whether it is jammed. If the entire sensor is found to be tilted and unable to spring back, it means the internal central axis has been strongly bent, and the entireL10602B00main body must be replaced. - Cleaning and anti-creepage of insulation board (L10772B00): There are insulating isolation components between the sensor and the robot’s sixth-axis flange. If a large amount of conductive metal dust accumulates here over a long period, it is highly likely to cause the high-voltage welding potential on the welding wire to reversely creep to the robot casing, instantaneously burning out the precision encoders inside the robot. Be sure to use dry compressed air to thoroughly blow out the dead-corner gaps above the sensor during daily inspections.
