Description

Technical Field

[0001] The utility model relates to the technical field of grabbing devices, in particular to a barrel unloading grabbing manipulator. Background Art

[0002] In the glass fiber industry, wire drawing operators use automatic unloading devices to complete the automatic unloading of the entire yarn ball. The unloaded barrels are usually placed on a matrix-arranged fixture, and then a three-axis robot is used to grab the unloaded barrels. However, the existing robots need to move for precise positioning when clamping, and can only grab one at a time. The grabbing efficiency is not high, which affects production efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a drum unloading grabbing manipulator to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drum unloading grabbing robot comprises a fixed plate, a plurality of grabbing mechanisms are arranged on the fixed plate, the grabbing mechanism comprises an electric cylinder fixedly arranged on the top of the fixed plate, the telescopic end of the electric cylinder passes through the fixed plate and is fixedly connected to a connecting frame, a first rotating shaft is fixedly arranged on one side of the connecting frame, two grabbing rods are rotatably connected to the outer surface of the first rotating shaft, a grabbing plate is fixedly connected to one side of the bottom end of the grabbing rod by a connecting bolt, a plurality of fixing frames are fixedly connected to the bottom end of the fixed plate by a plurality of fixing bolts, mounting grooves are provided on both sides of the fixing frame, the grabbing rod is rotatably connected to the inside of the mounting groove by a second rotating shaft, a slide groove is provided on the grabbing rod, and the first rotating shaft is provided inside the slide groove.

[0005] The following improvement is made in the solution of the present application: the grabbing mechanism is arranged in three groups, and the three groups of the grabbing mechanism are evenly arranged on the fixed plate.

[0006] The following improvement is made in the solution of the present application: the two grab bars are arranged in a staggered and symmetrical manner.

[0007] The following improvement is made in the solution of the present application: a plurality of connection holes are opened on the fixing plate, and the telescopic ends of the electric cylinder are arranged inside the connection holes.

[0008] The following improvement is made in the solution of the present application: a mounting seat is fixedly provided on the top end of the fixing plate.

[0009] Compared with the prior art, the utility model provides a drum unloading grabbing manipulator, which has the following beneficial effects:

[0010] The unloading barrel grabbing robot is provided with a plurality of grabbing devices on a fixed plate. When it is necessary to grab the unloading barrel, the electric cylinder is started, the electric cylinder extends and drives one end of two grabbing rods to move downward through a connecting frame and a first rotating shaft. Since the grabbing rods are rotatably connected to the fixed frame through a second rotating shaft, the other ends of the two grabbing rods move away from each other, so that the unloading barrel is located in the middle of the two grabbing rods. Subsequently, the electric cylinder is retracted, so that the other ends of the two grabbing rods are close to each other, thereby clamping the unloading barrel, so that multiple unloading barrels can be grabbed at one time, thereby improving the grabbing efficiency and thus improving the production efficiency.
