Description

Technical Field

[0001] The utility model relates to the technical field of industrial robots, in particular to a conveying collision protection device for industrial robots. Background Art

[0002] An industrial robot is a multi-joint manipulator or multi-degree-of-freedom machine device for the industrial field. It can perform work automatically and relies on its own power and control capabilities to achieve various functions. It can accept human commands or run according to pre-programmed programs. Modern industrial robots can also act according to the principles and guidelines formulated by artificial intelligence technology. Currently, industrial robots and manipulators are mostly rigidly connected and do not have a buffering function. When industrial robots convey products through manipulators, it is difficult for the manipulators to provide collision protection for the products. When the products fall to the ground, impact force will be generated, which can easily cause surface deformation of the products. It is not convenient to install and disassemble the device with the robot and the manipulator, and it is not convenient to remove the buffer spring inside the connecting tube for replacement, inspection and maintenance. Therefore, we propose a conveying collision protection device for industrial robots to solve this problem. Utility Model Content
