Description

Technical Field

[0001] The utility model relates to a replaceable silicone soft clip, in particular to a replaceable silicone soft clip for an industrial robot. Background Art

[0002] In the existing technology, when the industrial robot gripper grabs small irregular objects, there are problems: the gripper cannot grab accurately and there is a probability that the object will fall. The stability is not strong, accidents are prone to occur, and there are safety hazards. First, the electromagnet is used as the main component of the electromagnetic suction cup, and the power on and off of the grasping is controlled by PLC. The output voltage of PLC should be 12V~24V. The traditional gripper needs to control the solenoid valve through PLC to control the on and off of the gas to achieve the gripping of the gripper, while the electromagnetic suction cup only needs to be directly connected through the PLC signal to control the grasping.
