Description

Technical Field

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

[0002] Robots are increasingly being used in modern industrial production, logistics warehousing, and service industries. As a key component for robots to perform tasks, robotic arms undertake various important operations such as grasping, handling, and assembly. With the accelerating pace of production and the increasing level of automation, the operating speed and workload of robotic arms are constantly increasing.

[0003] In actual operation, due to operator negligence, such as failing to observe the robotic arm's operating status in time when multiple tasks are performed concurrently, or due to mechanical failures of the robot itself, such as sensor malfunction or control system abnormalities, collisions between the robotic arm's tip and other equipment frequently occur. Most existing robotic arms lack effective cushioning structures; once a collision occurs, the impact force acts directly on the robotic arm body, easily causing damage. This not only requires significant time and resources for repairs but also leads to production line shutdowns, greatly impacting the robotic arm's efficiency and increasing usage and maintenance costs. Therefore, those skilled in the art have provided a robotic arm with a cushioning structure to address the problems mentioned in the background section. Utility Model Content

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

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A robotic arm with a buffer structure includes a robotic arm body, a buffer frame, a first buffer plate, a second buffer plate, and an airbag. The buffer frame is bolted to the outer wall of the robotic arm body. The first buffer plate is provided on both the left and right sides of the buffer frame, and the second buffer plate is provided above and below the buffer frame. Airbags are fixedly installed on the left and right sides and the top and bottom sides of the buffer frame. The airbags are made of elastic rubber and are hollow inside. Each airbag has an air outlet at one end, which can be used for air release and air intake.

[0007] As a further embodiment of this utility model: each of the air outlets is fixedly installed with a whistle, wherein when the airbag is compressed and air is discharged, the airflow passing through the whistle will generate vibration and sound, and several sets of sliding grooves are opened at both the left and right ends of the buffer frame, and several sets of sliding grooves are opened at both the upper and lower ends of the buffer frame.

[0008] As a further embodiment of this utility model: several sets of spring rods are fixedly connected to one side of the buffer plate, and several sets of ball bearings are movably connected to the other side of the buffer plate; several sets of spring rods are fixedly connected to one side of the buffer plate, and several sets of ball bearings are movably connected to the other side of the buffer plate.

[0009] As a further embodiment of this utility model: each end of the spring rod is fixedly connected to a limiting ring, wherein the end of the spring rod with the limiting ring is slidably connected in the slide groove, and the limiting ring can prevent the spring rod from disengaging from the slide groove.

[0010] As a further embodiment of this utility model: one end of each of the two spring rods is fixedly connected to a limiting ring, wherein one end of the two spring rods with the limiting ring is slidably connected in the groove, and the limiting ring can prevent the two spring rods from disengaging from the groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Spring rod buffer protection: When encountering a collision, spring rod one and spring rod two will deform under force, using their own elasticity to absorb and buffer the impact force, effectively reducing the transmission of impact force to the main body of the robotic arm, reducing the damage to the robotic arm, and improving the structural stability and service life of the robotic arm.

[0013] 2. Ball bearing-assisted force relief: When encountering a collision, the ball bearings on buffer plate one or buffer plate two roll when in contact with the object, converting part of the force generated by the collision into other forms of force such as friction, further reducing the impact of the collision on the robotic arm and optimizing the buffering effect.

[0014] 3. Collision Warning: When a collision occurs, the airbag is compressed and expels air, causing the whistle to vibrate and emit a sound. This provides timely and intuitive reminders to the staff that the robotic arm has collided, allowing for a quick response and preventing further damage or accidents. After the compression is released, the airbag returns to its original position due to its elasticity, draws in air, and the sound stops. No manual reset is required, making it easy to use and allowing it to quickly return to its initial state without affecting subsequent work. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-6In this embodiment of the utility model, a robotic arm with a buffer structure includes a robotic arm body 1, a buffer frame 2, a first buffer plate 3, a second buffer plate 4, and an airbag 5. The buffer frame 2 is bolted to the outer wall of the robotic arm body 1. Buffer plates 3 are provided on both the left and right sides of the buffer frame 2, and second buffer plates 4 are provided above and below the buffer frame 2. Airbags 5 are fixedly installed on the left and right sides and the top and bottom sides of the buffer frame 2. The airbags 5 are made of elastic rubber and are hollow inside. Each airbag 5 has an air outlet 501 at one end, which can be used for air release and air intake. A whistle is fixedly installed inside each air outlet 501. When the airbag 5 is compressed and air is released, the airflow passes through the whistle and vibrates to produce sound. Several sets of sliding grooves 201 are provided at both the left and right ends of the buffer frame 2, and several sets of sliding grooves 201 are provided at both the top and bottom ends of the buffer frame 2. There are several sets of sliding grooves 202. Several sets of spring rods 301 are fixedly connected to one side of buffer plate 3, and several sets of ball bearings 302 are movably connected to the other side of buffer plate 4. Several sets of spring rods 401 are fixedly connected to one side of buffer plate 4, and several sets of ball bearings 402 are movably connected to the other side of buffer plate 4. One end of each spring rod 301 is fixedly connected to a limiting ring 303. The end of spring rod 301 with the limiting ring 303 is slidably connected to the sliding groove 201, and the limiting ring 303 can prevent spring rod 301 from disengaging from sliding groove 201. One end of each spring rod 401 is fixedly connected to a limiting ring 403. The end of spring rod 401 with the limiting ring 403 is slidably connected to the sliding groove 202, and the limiting ring 403 can prevent spring rod 401 from disengaging from sliding groove 202.

[0024] The working principle of this utility model is as follows: When the robotic arm collides with another object, the object first contacts the buffer plate 3 or the buffer plate 4 and is squeezed. At this time, the buffer plate 3 or the buffer plate 4 drives the connected spring rod 301 or the spring rod 401 to move towards the buffer frame 2. The spring rod 301 or the spring rod 401 deforms under force, absorbing and buffering the impact force generated by the collision through its own elasticity, reducing the transmission of the impact force to the main body 1 of the robotic arm, thereby reducing the damage to the robotic arm. At the same time, during the contact between the buffer plate 3 or the buffer plate 4 and the object, the ball bearing 302 or the ball bearing 402 on the buffer plate will contact the object and roll. The process changes the direction of the force, converting part of the force generated by the collision into other forms of force such as friction through rolling, thus relieving some of the force and further reducing the impact of the collision on the robotic arm. In addition, when the buffer plate 3 or the buffer plate 4 is squeezed and moves towards the buffer frame 2, it will squeeze the corresponding airbag 5. The airbag 5 is made of elastic rubber and is hollow inside. When compressed, it discharges air, which flows out from the air outlet 501 and passes through the whistle installed in the air outlet 501. The airflow causes the whistle to vibrate and make a sound, thereby reminding the staff that the robotic arm has collided. When the compression is released, the airbag 5 returns to its original position due to its elasticity, draws in air, and the sound stops.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
