Description

Technical Field

[0001] The utility model belongs to the technical field of manipulators, and particularly relates to a line auxiliary guiding mechanism for a rotary manipulator. Background Art

[0002] A manipulator is a new type of device developed in the process of automated production, which can imitate some action functions of human hands and arms to grasp, transport objects or operate tools according to a fixed program. A rotary manipulator refers to a manipulator with a rotating mechanism arranged on the upper part of the gripper to drive the gripper to rotate 360° on a horizontal plane; for the rotating mechanism of a common rotary manipulator, its wiring method is generally a fixed junction box or an aviation plug, and the power supply or gas source is connected to the gripper area below the manipulator. Since both the junction box and the aviation plug are fixed, during the 360° rotation of the gripper, the cables, gas sources and other lines are frequently worn and cracked, affecting the operation of the manipulator.

[0018] In order to better understand the purpose, structure and function of the present utility model, the present utility model will be described clearly and completely below with reference to the drawings.

[0019] As Figures 1 - 3 shown, a rotary manipulator line auxiliary guiding mechanism includes: a fixing plate 1, and a connecting assembly and a guiding assembly are provided on the fixing plate 1. The connecting assembly is used to connect the fixing plate 1 with the manipulator. In this embodiment, the fixing plate 1 is installed at the upper position of the end of the robotic arm and follows the movement of the robotic arm; specifically, the connecting assembly includes a first connecting plate 6 and a second connecting plate 7. The first connecting plate 6 is connected to the fixing plate 1, and the second connecting plate 7 is located above the first connecting plate 6 and connected to the first connecting plate 6. The first connecting plate 6 is fixedly connected to the fixing plate 1 and to the second connecting plate 7 by bolts; one end of the second connecting plate 7 extends beyond the fixing plate 1, and a connecting hole 8 is provided at the extending part, through which the robotic arm can be connected, so that the fixing plate 1 is installed on the robotic arm.

[0020] The guiding component drives the circuit to rotate synchronously with the rotation of the gripper, and includes a bearing seat 2, a bearing 3, and a guiding rod 4. The bearing seat 2 is installed on the fixed plate 1, specifically by bolts on the fixed plate 1. The bearing 3 is arranged inside the bearing seat 2, and the inner ring of the bearing 3 is connected to the guiding rod 4. During use, the fixed plate 1 is connected to the robotic arm. The axis of the bearing seat 2 is vertical, and the guiding rod 4 is fixed to the solenoid valve air supply pipe or power cord of the gripper using a strap. When the robotic gripper rotates, under the action of the two bearings 3, the guiding rod 4 rotates synchronously with the robotic gripper, without stress pulling on the robotic arm, and at the same time, it avoids cable wear and breakage during the operation process.

[0021] Further, the guiding rod 4 includes a vertical rod 4-1 and a horizontal rod 4-2. The vertical rod 4-1 is connected to the inner ring of the bearing 3, and the horizontal rod 4-2 is connected to the end of the vertical rod 4-1 and extends away from the fixed plate 1. When the robotic gripper rotates, the guiding rod 4 rotates synchronously with the robotic gripper. Under the action of the two bearings 3, the direction of the vertical rod 4-1 remains unchanged, and the horizontal rod 4-2 cooperates with the gripper to rotate 360°. When the present invention is installed on the swing arm of the robotic arm, during the rotation operation of the gripper, it can ensure that the power cord or air supply pipe moves synchronously with the rotation direction of the gripper on the guiding rod 4, without generating additional swing of the cable itself, avoiding pulling or wearing of the cable during the rotation of the gripper, and maintaining the efficient and stable operation of the robotic arm.

[0022] Further, two bearing seats 2 and two bearings 3 are provided in the guiding component, and the guiding rod 4 is respectively connected to the inner rings of the two bearings 3. The fixed plate 1 is also provided with a screw hole 5 for installing the solenoid valve on the fixed plate 1. The two sets of bearings 3 assist the rotation of the guiding rod 4, avoiding jamming of the guiding rod 4 during use, with good effect and stable operation of the robotic arm.
