Description

Technical Field

[0001] The utility model relates to the technical field of collaborative robots, and more specifically, to a highly secure collaborative robot. Background Art

[0002] As a new type of industrial robot, collaborative robots have removed the obstacles to human-machine collaboration and allowed robots to completely break free from the constraints of guardrails or cages. Their groundbreaking product performance and wide range of applications have opened a new era for the development of industrial robots.

[0003] After searching, a collaborative robot with an existing announcement number of CN218226664U includes a body, a mechanical arm, a camera, an adsorption mechanism, a clamping mechanism, a control module and an input module. The mechanical arm is installed on the body, and the gripping end of the mechanical arm is installed with a camera, an adsorption mechanism and a clamping mechanism. The input module is installed on the body and is used to input control instructions. The control module is electrically connected to the camera, the adsorption mechanism and the clamping mechanism, and controls the mechanical arm, the camera, the adsorption mechanism and the clamping mechanism to perform corresponding actions according to the control instructions. Different control instructions can be input through the input module to perform corresponding actions on different products, so as to reduce the deployment cost and transformation time of the utility model.

[0004] For collaborative robots, their external structure is made of metal. When working normally under the set program, they will not accidentally collide with workers. However, if the workers make an error during operation and enter the working range of the collaborative robot, accidental collision may occur, which poses a great safety hazard. Therefore, we have proposed a highly safe collaborative robot to solve the above problems. Utility Model Content

The damping ring of the protective frame is pushed and pulled to push the isolation frame, and the distance between the two groups of rubber plates is adjusted and fixed. During the operation of the operator, it is not easy to directly touch the mechanical clamp. When the operator approaches the mechanical clamp by mistake, the hand is isolated and blocked by the protective frame and the isolation frame and rubber plate on the outside, thereby improving the safety during the work.
