Problems solved by technology

[0003] Some robots used for transportation can use their own grippers to grab objects to complete the transportation and transfer of objects, but the shape of their grippers is fixed, and they are easy to fall off when grabbing special-shaped objects, causing damage to the objects, and they cannot be accurately grasped. Gripping force that damages fragile objects

Embodiment 1

[0044] see figure 1 , an anti-falling gripper for a robot, including a pair of clamping blocks 1, the clamping block 1 is provided with a push assembly 7 through a connecting rod, and the push assembly 7 includes a transverse rod and an electric rod. A chute is installed, the electric rod is arranged at both ends inside the chute, the telescopic end of the electric rod is connected with the clamping block 1, and the electric rod is used to provide clamping force, the structure is simple, and the manufacturing cost is reduced.

[0045] see Figure 1-5A pair of clamping blocks 1 are provided with a plurality of clamping modules on the opposite side walls. The clamping modules include an elastic storage tube 3, a sliding assembly 4 and a friction block 5. The elastic storage tube 3 is fixed on the clamping block 1, and the internal clamping block 1 is embedded An electromagnet 2 corresponding to the position of the elastic storage tube 3 is provided. The elastic storage tube 3 i...

Abstract

The invention discloses an anti-falling gripper for the robot, and belongs to the technical field of robots. The robot can adapt to objects in different shapes by arranging multiple clamping modules, clamping blocks are pushed through electric rods to clamp the objects, friction blocks are used for making contact with the clamping blocks to push sliding rods to move backwards, electrorheological fluid and first springs in the clamping module are extruded, the electrorheological fluid is controlled to be solidified through a controller, the clamping module is kept stable, meanwhile, the situation that an object is damaged due to too large clamping force is avoided, unstable current is generated by a radiation metal rod and a conductor rail through rotation of a ball in a spherical cavity, and therefore whether the clamping module is clamped or not is judged; and after the controller controls the electrorheological fluid to be liquefied, repulsive force is generated in cooperation with an electromagnet, so that the clamping module is tightly attached to the object, and the stability of the device is further improved.

Description

technical field [0001] The invention relates to the technical field of robots, and more specifically relates to a fall-off prevention gripper for a robot. Background technique [0002] A robot is an automated machine. The difference is that this machine has some intelligent abilities similar to humans or creatures, such as perception, planning, action, and coordination. It is a highly flexible automated machine. With the deepening of people's understanding of the intelligent nature of robot technology, robot technology has continuously penetrated into various fields of human activities. [0003] Some robots used for transportation can use their own grippers to grab objects to complete the transportation and transfer of objects, but their grippers have a fixed shape and tend to fall off when grabbing special-shaped objects, causing damage to the objects, and they cannot be accurately grasped. Gripping force, which causes damage to fragile objects. [0004] For this reason, ...
