gripper mechanism

Abstract

A gripper mechanism, applied in a handling device, is used to grip a carrier. The gripper mechanism includes a base, a gripper power unit, and two grippers. The gripper power unit is mounted on the base and includes at least one drive motor and at least one screw assembly. The drive motor is horizontally positioned, and the screw assembly is connected to the drive motor. The two grippers are connected to the screw assembly. The drive motor drives the two grippers through the screw assembly, enabling the grippers to grip or release the carrier. This achieves effects such as reduced height, high positioning accuracy, high thrust, and excellent rigidity. Multiple guide elements can be installed on the bottom side of the base for precise positioning of the carrier. Multiple guide blocks can be installed on the base for precise positioning with the upper guide posts.

Claims

1. A gripper mechanism applied to a transport device of an unmanned transport vehicle for conveying a carrier, the gripper mechanism comprising: A base; A gripper power assembly is provided on the base. The gripper power assembly includes at least one drive motor and at least one screw assembly. The at least one drive motor is arranged horizontally, and the at least one screw assembly is connected to the at least one drive motor. And two grippers, the two grippers being connected to the at least one screw assembly, the at least one drive motor of the gripper power assembly being able to drive the two grippers through the at least one screw assembly, so that the two grippers can grip or release the carrier.

2. The gripper mechanism as described in claim 1, wherein, The gripper power assembly includes two screw groups, each screw group having a screw and a nut. The screws of the two screw groups are horizontally arranged and located on the same straight line. The at least one drive motor is located between the screws of the two screw groups. The screws of the two screw groups are respectively connected to the two ends of the at least one drive motor. The nuts of the two screw groups are respectively screwed to the screws of the two screw groups. The two grippers are respectively connected to the nuts of the two screw groups.

3. The gripper mechanism as described in claim 1, wherein, The base is provided with multiple clamping mechanisms, which are respectively located near the front and rear sides of the base. Each clamping mechanism includes a connecting seat, a rotating shaft, and a clamping member. The connecting seat is disposed on the base, and the clamping member is pivotally connected to the connecting seat via the rotating shaft. The rotating shaft is horizontally arranged, and the clamping member can swing back and forth around the rotating shaft as the axis.

4. The gripper mechanism as described in claim 3, wherein, The connecting seat is secured to the base with at least two adjusting screws, and the height can be adjusted by rotating the at least two adjusting screws.

5. The gripper mechanism as described in claim 1, wherein, Multiple guide members are provided on the bottom side of the base. The multiple guide members are cone-shaped and can guide the vehicle to position.

6. The gripper mechanism as described in claim 1, wherein, The base is provided with multiple guide blocks, each of which has a guide hole, which can provide guidance and positioning.

7. The gripper mechanism as described in claim 1, wherein, The gripper mechanism further includes a brake connected to the at least one screw assembly, the brake providing a holding function.

8. The gripper mechanism as described in claim 7, wherein, The brake is arranged horizontally.
