Multidirectional collision preventing device of robot

Abstract

The invention relates to a multidirectional collision preventing device of a robot. The multidirectional collision preventing device of the robot is used for preventing collision when a manipulator moves horizontally and vertically. The multidirectional collision preventing device of the robot comprises a horizontal collision preventing unit, a vertical collision preventing unit and a sensing switch. The vertical collision preventing unit and the horizontal collision preventing unit are similar in structure and have the same collision preventing principle. The vertical collision preventing unit is installed above the horizontal collision preventing unit. The horizontal collision preventing unit comprises a left fixing base, a right fixing base and a horizontal guide rod perpendicularly installed between the left fixing base and the right fixing base. A collision preventing block is connected with the middle of the horizontal guide rod in a sleeving mode, and a C-type spring is installed at the position where the collision preventing block and the horizontal guide rod are connected in the sleeving mode. Springs are installed on the two sides of the collision preventing block, a connecting plate is fixed to the lower end of the collision preventing block, and a mechanical clamping jaw and the connecting plate are fixedly installed. When the mechanical clamping jaw horizontally moves and collides, the connecting plate and the collision preventing block bear collision force jointly, and the collision preventing block overcomes resistance of the C-type spring to move on the horizontal guide rod, so that the collision force is weakened suddenly, the sensing switch is triggered in the moving process to shut down the robot, and then the manipulator, a machine tool and the like are protected. After collision is relieved, the collision preventing block resets rapidly and accurately under action of the springs.

Description

technical field [0001] The invention belongs to the field of mechanical equipment and relates to a multi-directional anti-collision device for a robot. Background technique [0002] With the development of industrial automation, the production, processing and manufacturing of various large and medium-sized enterprises are becoming more and more intelligent. In addition, the current labor cost is getting higher and higher, so various robots are introduced into various small and medium-sized enterprises. The advantages of the robot are high efficiency, high quality, high speed, and can work continuously for a long time. However, collisions often occur during the use of robots, which not only affect work efficiency, but also damage parts and even machine tools, and sometimes endanger the personal safety of operators. [0003] The current common robot anti-collision devices have the following problems: [0004] 1. Can only avoid collision in one or two directions; [0005] 2....

AI Technical Summary

Problems solved by technology

[0004] 1. Can only avoid collisions in one or two directions;

[0005] 2. The anti-collision device has no obvious unloading or weakening effect on the force of the collision. When the collision force is too large, the anti-collision mechanism will be damaged and the anti-collision effect cannot be achieved;

[0006] 3. During the sudden acceleration and movement of the manipulator, due to the unbalanced force of the manipulator, it is easy to shake;
