Description

Technical Field

[0001] The utility model relates to the field of automatic feeding equipment of a mechanical arm, in particular to an anti-drop device for automatic feeding of a mechanical arm. Background Art

[0002] Automatic loading by robotic arms is a common technical application in automated production lines. It refers to the process of automatically grabbing materials and placing them accurately in designated locations by robotic arms installed on the production line according to preset programs and instructions. This process realizes unmanned and automated material handling and loading, which helps to improve production efficiency, reduce human errors, save labor costs, and achieve continuous, stable and precise production operations.

[0003] When existing robotic arms grasp soft or fragile materials, the grasping force is usually small to avoid damaging the materials. At this time, the materials may fall due to shaking during transportation, thus affecting material handling.

[0004] Therefore, in order to solve the above problems, a kind of anti-drop device for automatic feeding of mechanical arms has been developed, which can improve the grasping stability of materials and prevent materials from falling during the grasping process. Utility Model Content

The left and right parts of the mounting frame are rotatably connected to the rotating frame, the lower part of the rotating frame is connected to a connecting plate, the connecting plates are connected to grabbing assemblies, the lower middle part of the mounting frame is connected to an electric push rod, the telescopic end of the electric push rod is connected to a pneumatic suction cup, the connecting plates are connected to intercepting assemblies, the rotating frame drives the connecting plate to rotate to grab the material, the telescopic end of the electric push rod drives the pneumatic suction cup to move downward to contact the material, and the pneumatic suction cup is used to absorb and fix the material.

[0007] As a further preferred embodiment, the grabbing assembly includes a grabbing airbag, a grabbing head and an air pressure controller. The adjacent sides of the connecting plate are connected to the grabbing airbags, the lower sides of the grabbing airbags are connected to the grabbing heads, and the non-adjacent sides of the middle of the connecting plate are connected to the air pressure controller. After the connecting plate rotates to drive the grabbing airbag and the grabbing head to contact the material, the air pressure controller controls the inflation of the airbag, so that the material can be wrapped according to its shape and the material is fixed between the grabbing airbags.

[0008] As a further preferred solution, the grabbing head is an elastic structure.

[0009] As a further preferred solution, the grabbing heads are all arranged at an angle to facilitate grabbing of materials.

[0010] As a further preferred solution, the interception component includes a pneumatic actuator, a flip block and an opening and closing cover. The pneumatic actuator is connected to non-adjacent sides of the upper part of the connecting plate. The pneumatic actuator is rotatably connected to the flip block, and the flip block is connected to the opening and closing cover. After grabbing the material, the pneumatic actuator is used to control the flip block to rotate, and the rotation of the flip block drives the opening and closing cover to rotate and close, and the slipping material is intercepted by the opening and closing cover to prevent the material from falling.

[0011] As a further preferred solution, the opening and closing cover forms a hemispherical structure when closed, which is convenient for intercepting slipping materials.

[0012] The utility model has the following advantages: the utility model controls the inflation of the airbag through an air pressure controller to wrap the material according to its shape, and then controls the rotation of the flip block through a pneumatic actuator. The rotation of the flip block drives the opening and closing cover to rotate and close to intercept the slipping material, which can improve the grasping stability of the material and prevent the material from falling during the grasping process.
