Description

A fall-prevention robot gripper

Technical Field

The utility model belongs to the technical field of robot grippers, in particular to an anti-falling robot gripper.

Background Art

A robotic gripper is a device that imitates human hand and arm movements to grasp, move objects or operate tools. It has been widely used in the field of industrial manufacturing. However, due to the different sizes and shapes of workpieces, some grippers are prone to workpieces slipping off the gripper arms during the process of grasping and transporting, which can easily cause grasping failure.

The patent with publication number CN219946268U discloses a robot gripper with an anti-fall design. The utility model can produce a certain interception effect on the workpiece after the workpiece enters the interior of the grabbing arm through the setting of supporting springs and anti-fall blocks, making it difficult for the workpiece to fall from the grabbing arm. In addition, the anti-slip teeth can increase the friction effect between the grabbing arm and the workpiece after closing, so as to further prevent the workpiece from falling downward and improve the stability and reliability of the grabbing.

However, when the above device is in use, it is difficult to unload the workpiece due to the limitations of the anti-fall block and the anti-slip teeth, and the grab arm needs to be greatly expanded. Some workpieces may also tilt and get stuck on the anti-fall block during unloading, making operation inconvenient.

Preferably, a connecting rod is provided on the support plate.

The utility model adopts the above structure to achieve the following beneficial effects: the utility model provides an anti-fall robot gripper, which, by setting a worm gear and a worm, can be driven by a motor to rotate the worm gear, thereby driving the support plate to deflect, thereby facilitating the support of the clamped materials to prevent the materials from slipping. At the same time, when unloading, the angle of the support plate can be adjusted first to prevent the materials from getting stuck.
