Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1 to 3, the swing material taking and placing device according to the embodiment of the present invention includes a rack 10, a rocker arm 20, a manipulator 30, and a driving mechanism 50; the driving mechanism 50 is disposed on the frame 10 and is in transmission connection with the swing arm 20 for driving the swing arm 20 to swing back and forth. The robot 30 has a rotation shaft 31 rotatably mounted on the swing arm 20, and the robot 30 can rotate about the rotation shaft 31 by its own weight during the swing of the swing arm 20, thereby always maintaining a horizontal posture.

The utility model discloses in, rocking arm 20 can be rocked at a high speed making a round trip under actuating mechanism 40's drive for install the manipulator 30 on rocking arm 20 constantly make a round trip the fixed point switch between getting material position and blowing position, not only have simple structure, advantage that area occupied is little, and the motion efficiency is high moreover, can get at a high speed and put the material operation.

In an alternative embodiment, the swing arm 20 has a first end and a second end disposed opposite to each other, the robot 30 is rotatably disposed at the first end of the swing arm 20, and the driving mechanism 50 is drivingly connected to the second end of the swing arm 20. In an alternative embodiment, the driving mechanism 50 includes a servo motor 51 and a reducer 52, and the reducer 52 is fixedly connected to the second end of the rocker arm 20.

Further, the swing arm 20 is provided with a posture stabilizing mechanism for keeping the manipulator 30 at a fixed angle all the time during the rotation of the swing arm 20, for example, keeping the manipulator 30 at a horizontal state all the time. Specifically, as shown in fig. 2, the posture stabilizing mechanism is provided in the housing of the swing arm 20, and includes a fixed pulley 41, a rotating pulley 42, a tension pulley 43, and a belt 44. Wherein, the fixed wheel 41 and the rocker arm 20 are relatively fixed; in an alternative embodiment, the frame 10 is provided with a support shaft 11 for rotatably supporting the swing arm 20, and the fixed pulley 41 is coaxially disposed with the support shaft 11.
