Abstract

This utility model relates to the field of robotics technology and discloses a multi-joint anti-collision buffer structure for robots, including a robot base, a robot frame, a drive device, a first joint arm, a second joint arm, a gripper, and an anti-collision buffer mechanism. The anti-collision buffer mechanism includes a sleeve, a movable plate, guide posts, springs, and joint arm connecting ends. The sleeve has a movable cavity inside, and the movable plate is slidably disposed within the movable cavity. Multiple sets of guide posts are disposed within the sleeve, and the movable plate is slidably fitted onto the guide posts. Joint arm connecting ends are disposed on the movable plate. The anti-collision buffer mechanism, through the cooperation of the sleeve, movable plate, guide posts, and springs, effectively buffers the impact when the robot joints collide. When the robot joint is subjected to external impact, the movable plate slides within the movable cavity of the sleeve, compressing the springs, thereby absorbing and dispersing the impact force and reducing damage to the joint components.

Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a multi-joint anti-collision buffer structure for robots. Background Technology

[0002] In modern robotics, the multi-jointed design of robots gives them greater flexibility and adaptability, leading to their widespread application in various fields such as industry, medicine, and service. However, because robots need to perform complex movements and posture adjustments when performing tasks, joint collisions have become a significant factor affecting their stability and safety. Especially in multi-jointed movements, collisions between robots can cause damage to joint components and even affect the efficiency and lifespan of the entire system.

[0003] Traditional robot joint designs rely heavily on rigid mechanical structures and lack sufficient cushioning mechanisms. In the event of a collision, the joint components often fail to effectively disperse the impact force, making them prone to damage. Moreover, as the demand for robots to perform tasks in complex environments increases, traditional designs also exhibit significant shortcomings in terms of flexibility and safety.

[0004] Therefore, proposing a multi-joint anti-collision buffer structure for robots is of significant technical importance. This structure, through the design of appropriate buffer materials or devices, can reduce the transmission of impact forces during collisions, minimize damage to mechanical components, and improve the safety and stability of the robot. Utility Model Content

[0005] The purpose of this invention is to provide a multi-joint anti-collision buffer structure for robots to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A robot multi-joint anti-collision buffer structure technical solution includes a robot base, a robot frame, a drive device, a joint arm one, a joint arm two, a gripper, and an anti-collision buffer mechanism.

[0008] The anti-collision buffer mechanism includes a sleeve, a movable plate, a guide column, a spring, and a joint arm connecting end;

[0009] The sleeve has a movable cavity inside, and the movable plate is slidably disposed in the movable cavity. The sleeve has multiple sets of guide posts, and the movable plate is slidably fitted onto the outside of the guide posts. The movable plate has a joint arm connecting end, which passes through the sleeve and is used to connect a joint.

[0010] The spring is sleeved on the guide post and located between the movable plate and the inner wall of the sleeve to provide a buffering force.

[0011] As a preferred technical solution, the sleeve is fixedly installed on the robot base frame or each articulated arm, and the articulated arm connecting end is fixedly connected to articulated arm one or articulated arm two.

[0012] As a preferred technical solution, the spring is a compression spring, with its two ends abutting against the movable plate and the inner wall of the sleeve, respectively.

[0013] As a preferred technical solution, the sleeve, movable plate, and guide post are made of metal.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention relates to a collision-resistant buffer structure for multi-joint robots. The collision-resistant buffer mechanism, through the cooperation of a sleeve, a movable plate, a guide post, and a spring, effectively buffers the impact when robot joints collide. When a robot joint is subjected to external impact, the movable plate slides within the movable cavity of the sleeve, compressing the spring, thereby absorbing and dispersing the impact force and reducing damage to the joint components. This design not only improves the robot's safety but also extends its service life.

[0016] Meanwhile, this structure has wide applicability, allowing for easy installation on the robot's chassis or individual articulated arms, and fixed connection with articulated arm one or articulated arm two, without requiring large-scale modifications to the robot's original structure. Furthermore, the use of metal materials for the sleeves, movable plates, and guide pillars ensures the structure's strength and stability.

[0017] In summary, the robot multi-joint anti-collision buffer structure of this utility model, through innovative design, effectively solves the shortcomings of traditional robot joint design in collision protection, and provides a strong guarantee for the safe and stable operation of the robot.
