Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to a robotic arm with a protective structure. Background Technology

[0002] A robotic arm is an automated operating device that can mimic certain movements and functions of a human hand and arm to grasp, move objects, or operate tools according to a fixed program. Its characteristic is that it can be programmed to complete various expected tasks, and its structure and performance combine the advantages of both humans and machines.

[0003] During use, the robotic arm needs to repeatedly rotate and grip the parts to be processed. There are many power devices around the robotic arm, so the gripper is prone to colliding with surrounding objects when rotating and gripping the parts. The gripper connection is relatively fragile and is easily damaged by collision. In addition, when a collision occurs, the gripper is prone to dropping the gripped goods. Utility Model Content

[0004] The purpose of this invention is to provide a robotic arm with a protective structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a robotic arm with a protective structure, comprising a robotic arm, a sliding groove on the robotic arm, symmetrically arranged transmission blocks slidably connected inside the sliding groove, an installation groove on the robotic arm, symmetrically arranged connecting grooves corresponding to the installation groove positions on the robotic arm, symmetrically arranged transmission gears rotatably connected inside the installation groove, symmetrically arranged rotating rods rotatably connected inside the installation groove corresponding to the middle positions of the transmission gears, a blocking member fixedly connected to the middle position of each rotating rod, a driven gear fixedly connected to the bottom position of each rotating rod corresponding to the blocking member, grippers fixedly connected to each transmission block, and toothed blocks provided at the positions corresponding to the transmission gears on each transmission block.

[0006] Preferably, the sliding groove is T-shaped, and the transmission block is also T-shaped.

[0007] Preferably, the connecting groove, the sliding groove, and the mounting groove are in communication.

[0008] Preferably, the tooth blocks all pass through the sliding groove and the connecting groove and mesh with the transmission gear, and the transmission gears all mesh with the driven gear.

[0009] Preferably, the spacing between the blocking members is greater than the spacing between the grippers.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the blocking component and the gripper are linked, and when the gripper opens or closes, the linkage of each component will cause the blocking component to open and close. No matter how large the opening distance of the gripper is, the distance between the two blocking components is always greater than the opening angle of the gripper, so that the blocking component provides basic protection for the gripper and prevents the gripper from being damaged by collision or the goods from falling off during the rotation of the robotic arm. Moreover, this utility model has a simple structure and strong practicality. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a robotic arm with a protective structure, including a robotic arm 1, a sliding groove 2 on the robotic arm 1, symmetrically arranged transmission blocks 3 slidably connected inside the sliding groove 2, an installation groove 4 on the robotic arm 1, symmetrically arranged connecting grooves 5 on the robotic arm 1 corresponding to the installation groove 4, symmetrically arranged transmission gears 6 rotatably connected inside the installation groove 4, symmetrically arranged rotating rods 7 rotatably connected inside the installation groove 4 corresponding to the middle position of the transmission gears 6, a blocking member 8 fixedly connected to the middle position of each rotating rod 7, a driven gear 9 fixedly connected to the bottom position of each rotating rod 7 corresponding to the blocking member 8, a gripper 10 fixedly connected to each transmission block 3, and a toothed block 11 on each transmission block 3 corresponding to the position of the transmission gear 6.

[0017] The sliding groove 2 is T-shaped, and the transmission blocks 3 are also T-shaped. The transmission blocks 3 can slide inside the sliding groove 2. The connecting groove 5, the sliding groove 2, and the mounting groove 4 are in a connected state, which facilitates the meshing connection between the toothed blocks 11 and the transmission gears 6. The toothed blocks 11 all pass through the sliding groove 2 and the connecting groove 5 to mesh with the transmission gears 6. When the toothed blocks 11 move, they can easily drive the transmission gears 6 to rotate. The transmission gears 6 all mesh with the driven gears 9, which can easily drive the driven gears 9 to rotate. The distance between the blocking members 8 is greater than the distance between the grippers 10.

[0018] Specifically, when using this utility model, when the transmission block 3 slides inside the sliding groove 2, it will drive the gripper 10 and the tooth block 11 to move together. At this time, the two grippers 10 will open, increasing the distance between the two grippers 10, so that the workpiece can be gripped. At the same time, the movement of the tooth block 11 will also drive the transmission gear 6 to rotate. The transmission gear 6 will drive the driven gear 9 to rotate. The driven gear 9 will drive the rotating rod 7 and the blocking member 8 to rotate. At this time, the two grippers 10 and the two blocking members 8 will open simultaneously. When the two blocking members 8 are not running, the distance between them is greater than the distance between the two grippers 10. When running, the distance between the blocking members 8 is still greater than the distance between the grippers 10. When an external object is hit, the blocking member 8 will collide first, thus providing protection for the grippers 10 and preventing the grippers 10 from being damaged or the workpiece from falling due to collision during the rotation of the robotic arm 1.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
