Description

Technical Field

[0001] This utility model relates to the field of ground rail technology, specifically a shock-absorbing and noise-reducing robot seventh-axis ground rail. Background Technology

[0002] Industrial robot arms have limited movement space, making it difficult to meet requirements. Therefore, a linear axis is needed to equip the industrial robot, allowing it to first move as a whole to a position accessible to the robot arm, which then performs the corresponding actions. This is the origin of the seventh-axis ground-rail robot; the seventh-axis ground rail is the robot's linear running track.

[0003] The current type of vibration reduction and noise reduction robot seventh-axis ground rail uses flexible top columns to achieve vibration reduction. However, the vibration reduction effect of these flexible top columns is easily affected by load changes, which reduces the stability of the robot during operation and is not conducive to subsequent use. At the same time, the robot is prone to generating noise when moving in the ground rail, which can easily damage the surrounding environment and reduce the comfort and safety of the working environment.

[0004] In summary, this utility model solves the problems in the background art by designing a vibration-damping and noise-reducing robot seventh-axis ground track. Utility Model Content

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

[0007] A vibration-damping and noise-reducing robot seventh-axis ground rail includes a ground rail base and a robot mounted on the ground rail base. Foot supports are fixedly installed on the outer side of the ground rail base. A ground rail groove, noise-reducing blocks, and a sound-absorbing plate are respectively provided on the top of the ground rail base. Sound-absorbing layers are provided on the inner walls of both sides of the ground rail groove. A ground rail is provided on the inner wall of the bottom end of the ground rail groove.

[0011] As a preferred embodiment of this utility model, the top surface of the noise reduction block is in contact with the bottom surface of the sound-absorbing plate, and it is made of foam material. The bottom surface of the mounting block is fixed to the top surface of the ground rail base, and the cross-sectional shape of the sound-absorbing plate is a honeycomb structure.

[0012] As a preferred embodiment of this utility model, the first support plate has a U-shaped structure, the second support plate has an L-shaped structure, the sound-absorbing plate is located at the bottom of the horizontal end of the second support plate, and neither of them is in contact with the surfaces of the second support plate or the first support plate.

[0013] As a preferred embodiment of this utility model, the top ends of the support column and the shock-absorbing spring are both fixedly connected to the bottom surface of the mounting plate, and the top end of the positioning column slides through the bottom surface of the mounting plate and extends upward.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, by setting a vibration-damping and noise-reducing robot seventh-axis ground rail, the structural design of the vibration damping mechanism, combined with the vibration damping air cylinder and vibration damping spring, can effectively absorb and disperse the vibration energy generated during the robot's movement, thereby effectively reducing the vibration amplitude of the ground rail, facilitating the stable operation of the robot, and benefiting subsequent use.

[0017] 2. In this utility model, a vibration-damping and noise-reducing robot seventh-axis ground rail is designed.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] For examples, please refer to Figure 1-6 This utility model provides a technical solution:

[0030] A vibration-damping and noise-reducing robot seventh-axis ground rail includes a ground rail base 1 and a robot 2 mounted on the ground rail base 1. Foot supports 3 are fixedly installed on the outer side of the ground rail base 1. A ground rail groove 4, noise-reducing blocks 5, and a sound-absorbing plate 6 are respectively provided on the top of the ground rail base 1. Sound-absorbing layers 401 are provided on the inner walls of both the left and right sides of the ground rail groove 4. A ground rail 402 is provided on the inner wall of the bottom end of the ground rail groove 4. A sliding block 403 is fitted onto the outer side of the ground rail 402. A first support plate 7 is provided on the top of the sliding block 403. A second support plate 8 is fixedly installed on the outer side of the first support plate 7. Mounting blocks 601 are fixedly installed on both the front and rear sides of the bottom of the sound-absorbing plate 6. A mounting plate 201 is provided on the bottom of the robot 2. A vibration-damping mechanism 9 is provided between the mounting plate 201 and the second support plate 8.

[0031] Specifically, the ground track groove 4 is located on the left and right sides of the top of the ground track base 1, the sound-absorbing layer 401 is embedded in the inner wall of the ground track groove 4, the top surface of the noise reduction block 5 is in contact with the bottom surface of the sound-absorbing plate 6, and it is made of foam material, the bottom surface of the mounting block 601 is fixed to the top surface of the ground track base 1, and the cross-sectional shape of the sound-absorbing plate 6 is a honeycomb structure.

[0032] In this embodiment, the sound-absorbing layer 401 absorbs the sound waves generated when the sliding block 403 and the ground rail 402 move, effectively reducing the reflection of sound waves inside the ground rail groove 4. The noise reduction block 5 further enhances the noise reduction effect of the ground rail 402, thus meeting the noise reduction requirements of the ground rail 402.

[0033] Specifically, the first support plate 7 has a U-shaped structure, the second support plate 8 has an L-shaped structure, and the sound-absorbing plate 6 is located at the bottom of the horizontal end of the second support plate 8, and neither of them is in contact with the surface of the second support plate 8 or the first support plate 7.

[0034] In this embodiment, the sound-absorbing panel 6 effectively expands the sound-absorbing area, thereby improving the sound absorption efficiency.

[0035] In this embodiment, please refer to Figure 1 , Figure 5 and Figure 6The shock absorption mechanism 9 includes a positioning column 901, a shock absorption cylinder 902 and a shock absorption spring 903 respectively installed on the top surface of the second support plate 8. The bottom of the outer side of the shock absorption cylinder 902 is provided with an air injection valve port 904. The inside of the shock absorption cylinder 902 is provided with a limit pressure plate 905, and its top is provided with a support column 906.

[0036] Specifically, the top ends of the support column 906 and the shock-absorbing spring 903 are fixedly connected to the bottom surface of the mounting plate 201. The top end of the positioning column 901 slides through the bottom surface of the mounting plate 201 and extends upward. The bottom end of the support column 906 passes through the top surface of the shock-absorbing air cylinder 902 and is fixed to the top of the limiting pressure plate 905. The outer surface of the limiting pressure plate 905 slides in a sealed fit with the inner wall of the shock-absorbing air cylinder 902.

[0037] In this embodiment, the positioning column 901 ensures that the mounting plate 201 and the second support plate 8 remain stable. The support column 906 is mainly used to drive the limiting pressure plate 905, causing the limiting pressure plate 905 to compress the gas inside the shock-absorbing air cylinder 902. At the same time, with the setting of the shock-absorbing spring 903, it is easy to absorb and disperse the vibration energy generated when the robot 2 moves, thus meeting the stability requirements of the robot 2 operation.

[0038] The working process of this utility model is as follows: When using a vibration-damping and noise-reducing robot seventh-axis ground rail, the foot support block 3 is first used to fix the ground rail base 1 in the desired position. Then, the robot 2 can move by the sliding engagement of the sliding block 403 and the ground rail 402. During the movement of the robot 2, the sound-absorbing layer 401 initially absorbs the sound waves generated when the sliding block 403 and the ground rail 402 move. The sound-absorbing plate 6 and the noise-reducing block 5 further absorb and dissipate the remaining sound waves, ensuring the noise reduction effect of the ground rail 402. When robot 2 generates vibration energy during movement, it drives the mounting plate 201 to displace the support column 906 and compress the shock-absorbing spring 903. At this time, the positioning column 901 slides against the inner wall of the mounting plate 201, ensuring the relative position stability between the mounting plate 201 and the second support plate 8. Subsequently, the support column 906 drives the limiting pressure plate 905 to gradually move down. Through the synergistic effect of the shock-absorbing spring 903 and the shock-absorbing air cylinder 902, the impact force of robot 2 during operation is effectively buffered, improving the practical effect of the ground rail 402.

[0039] 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.
