Description

Technical Field

[0001] The utility model belongs to the technical field of robot sensors, and in particular relates to an anti-collision sensor for a robot. Background Art

[0002] With the advancement of science and technology, more and more mobile robots, both those used in manufacturing factories and ordinary civilian robots, are being put into use; among these robots, there are a large number of mobile robots that need to move by themselves. However, robots are not living things after all, and they do not have a tactile system. Robots mainly rely on cameras to perceive the environment. However, cameras have large visual angles. Therefore, during the movement of robots, it is easy for them to collide with other objects actively or passively, causing damage to the robot's sensors. However, the existing robots and sensors are fixedly connected by bolts. After long-term use, the bolts corrode and rust, making it inconvenient to disassemble and replace damaged sensors.

[0024] A collision prevention sensor for a robot comprises a rotating arm body 1 of the robot.

[0025] In this embodiment: In order to solve the technical problems existing in the prior art, as disclosed in the background technology above, "the camera has large visual corners. Therefore, during the movement of the robot, it is easy to collide with other objects actively or passively, causing damage to the robot's sensor. However, the existing robots and sensors are fixedly connected by bolts. After long-term use, the bolts corrode and rust, making it inconvenient to disassemble and replace the damaged sensors." Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a convenient limit assembly 3 is added on this basis.

[0028] The convenient disassembly limiting assembly 3 includes a limiting hole 31 provided on the anti-collision sensor 2 and a limiting mechanism 32 provided on the rotating arm body 1 .

[0029] In an optional embodiment, the limiting mechanism 32 includes a socket 326 and a limiting sliding cavity 321 opened on the rotating arm body 1, and a limiting sliding disk 322 is arranged inside the limiting sliding cavity 321. The limiting sliding disk 322 has a fixed limiting head 323 on the left side, and a fixed pull rod 324 on the right side.

[0030] In an optional embodiment, the limiting sliding plate 322 matches the limiting sliding cavity 321 , and the limiting sliding plate 322 slides left and right inside the limiting sliding cavity 321 .

[0031] In an optional embodiment, a spring 325 is sleeved on the pull rod 324 inside the limiting sliding cavity 321 , and the limiting sliding cavity 321 and the insertion hole 326 are communicated with each other.

[0032] In this embodiment: the pull rod 324 is pulled outward, the pull rod 324 drives the limit sliding plate 322 to slide inside the limit sliding cavity 321, and compresses the spring 325, and the limit head 323 moves with the limit sliding plate 322, and the pulling force applied by the pull rod 324 is released, the limit sliding plate 322 is reset under the action of the spring 325, and the limit head 323 is reset accordingly.

[0033] In an optional embodiment, the limiting hole 31 matches the limiting head 323 , and the limiting head 323 is snap-fitted into the limiting hole 31 .

[0035] Working principle of this utility model:

[0036] The pull rod 324 is pulled outward, and the pull rod 324 drives the limiting sliding plate 322 to slide inside the limiting sliding cavity 321 and compress the spring 325, and the limiting head 323 follows the movement of the limiting sliding plate 322. At this time, the limiting head 323 disengages from the limiting hole 31 on the anti-collision sensor 2, and then the anti-collision sensor 2 is pulled out from the socket 326 on the rotating arm body 1 to complete the disassembly of the sensor. On the contrary, one end of the anti-collision sensor 2 is plugged into the socket 326, and then the pulling force applied by the pull rod 324 is released. The limiting sliding plate 322 is reset under the action of the spring 325, and the limiting head 323 follows the reset. At this time, the limiting head 323 is clamped in the limiting hole 31 of the anti-collision sensor 2 for limiting, completing the replacement of the sensor.
