Claims

[Scope of utility model registration request]

An overload prevention device for an industrial robot interposed between a hand and a hand moving means, the device comprising: one member fixed to the hand moving means; and the other member movably supporting the hand. and the one member and the other member are arranged to face each other, and the other member is arranged so as to be movable and tiltable in a direction toward and away from the one member, and further, the other member has: A slide block is provided so as to be movable along a direction in which the other member approaches and leaves the one member, and a pressure is applied to the other member to move the slide block in conjunction with the movement of the hand relative to the other member. A block is provided, and a first stage spring is provided which urges the slide block and the pressing block in a direction away from the one member, and a spring that is stronger than the first stage spring is provided between the one member and the other member. A second stage spring is interposed between the other member and the slide block to strongly urge the other member in a direction away from the one member, and further to detect movement of the slide block with respect to the other member. Overloading of an industrial robot, characterized in that an evacuation operation sensor is provided, and an emergency stop sensor is provided between the one member and the other member to detect movement of the other member with respect to the one member. Prevention device.
