[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0021] The embodiments of the present application provide an anti-collision structure for the robotic arm of a robot, thereby solving the problem in the prior art that robotic arms in some service industries, such as robotic arms for beverage making, are often exposed to the outside by customers or staff walking around on site. Collisions may cause damage to the robotic arms or injuries to personnel, thereby causing losses. If a bracket is welded on for protection, the traditional protective bracket is not easy to remove quickly, and the operating space inside the bracket is small, which makes subsequent inspection and maintenance work inconvenient.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] The utility model discloses a robot arm anti-collision structure according to the attached Figure 1-4 As shown, it includes a protective base 2 arranged at the bottom of the robot arm body 1, and a crash frame 3 is rotatably connected to the protective base 2, and an inspection door 35 is provided on the crash frame 3;

[0024] A positioning block 21 is provided on the protective base 2, and a locking assembly 4 for limiting the position of the positioning block 21 is provided on the anti-collision frame 3. The locking assembly 4 includes a sleeve 41 arranged on the anti-collision frame 3 and an adjustment block 42 movably connected to the inside of the sleeve 41. A locking rod 43 is provided on the adjustment block 42. A positioning hole 211 is opened on the positioning block 21, and the locking rod 43 is movably inserted into the positioning hole 211.

[0025] The robot's robotic arm anti-collision structure adopts the design of a protective base 2 and an anti-collision frame 3, which is convenient for providing all-round protection for the robotic arm body 1. On the one hand, it is convenient for the robotic arm body 1 to be displayed, and on the other hand, it makes the robotic arm body 1 easy to repair. During maintenance, two maintenance methods are provided. During simple maintenance, the maintenance door 35 can be directly opened for maintenance. When complex maintenance and repair operations are required, the locking assembly 4 is directly used to unlock the anti-collision frame 3, and then the anti-collision frame 3 is lifted up, thereby expanding the maintenance and repair space for the staff to the anti-collision frame 3, making the maintenance and repair of the anti-collision frame 3 convenient.

[0026] The two groups of adjustment blocks 42 are fixedly connected with a spring 44, and the side wall of the adjustment block 42 is fixedly connected with a push handle 45. The locking assembly 4 provided in the device has a simple structure, and the locking assembly 4 has a good effect of fixing the position of the anti-collision frame 3. When the anti-collision frame 3 needs to be locked in position, the anti-collision frame 3 is first rotated and the two groups of push handles 45 are pulled at the same time, so that the push handles 45 drive the adjustment block 42 and the locking rod 43 to move and squeeze the spring 44. At this time, the anti-collision frame 3 drives the sleeve 41 to move between the two groups of positioning blocks 21. Release the push handle 45, the spring 44 resets and pushes the adjustment block 42 and the locking rod 43 to move, so that the locking rod 43 is inserted into the inside of the positioning hole 211, thereby realizing rapid locking of the anti-collision frame 3, having a good locking effect on the anti-collision frame 3, and having a good protection effect on the robot arm main body 1.

[0027] A shaft sleeve 22 is provided on the protective base 2, and a main shaft 32 is provided on the anti-collision frame 3. The main shaft 32 is movably inserted into the shaft sleeve 22. Through the design of the main shaft 32 and the shaft sleeve 22, the anti-collision frame 3 is rotatably connected to the protective base 2 and the connection is stable.

[0028] A first magnet block 23 is provided on the protective base 2, and a second magnet block 33 corresponding to the position of the first magnet block 23 is provided on the anti-collision frame 3. Through the design of the first magnet block 23 and the second magnet block 33, the device enables the first magnet block 23 and the second magnet block 33 to be adsorbed after the anti-collision frame 3 is unlocked and lifted up, thereby achieving adsorption and temporary fixation between the anti-collision frame 3 and the protective base 2.

[0029] A transparent acrylic plate 31 is provided on the anti-collision frame 3, and a handle 34 is provided on the anti-collision frame 3. The design of the transparent acrylic plate 31 ensures that the anti-collision frame 3 is protective while ensuring beauty, and the interior is clearly visible. The design of the handle 34 makes the anti-collision frame 3 easy to operate when lifting and rotating.
