Description

Technical Field

[0001] The utility model relates to the technical field of robot devices, in particular to an automatic robot device. Background Art

[0002] A robot is an automated device or system that can perform a variety of tasks, and its behavior is usually controlled by programs or remote controls. With the continuous advancement of science and technology and the expansion of application scenarios, robotics technology has developed rapidly. In terms of handling robots, with the continuous advancement of sensor technology, control technology, and artificial intelligence, modern handling robots have become more intelligent and autonomous.

[0003] A robot automatic handling and clamping device in the prior art (Announcement No.: CN220617370U) uses a gravity trigger plate. When the gravity trigger plate is subjected to gravity, the gravity trigger plate and the trigger rack will move downward. Under the meshing action, the gear column rotates, causing the two clamping racks to move in a direction close to each other, driving the moving plate and the clamping plate to move together, clamping the objects in the two clamping plates to form a fixation. However, when the device encounters a bumpy road section during the process of carrying objects, the objects will be lifted up to a certain height, thereby weakening the gravity trigger plate, and the clamping force of the clamping plates on both sides becomes loose, and the objects being carried will tilt and fall. Therefore, it is urgent to design an automatic robot device with a more stable handling process. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an automatic robot device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0022] Reference Figure 1-Figure 4 The automatic robot device includes a robot body 1, a mounting groove is provided in the robot body 1, a storage seat 2 for placing objects to be transported is fixedly installed in the mounting groove, two lifting cylinders 3 are symmetrically fixedly installed on the top of the robot body 1, a lifting rod 4 is slidably installed in each lifting cylinder 3, a positioning block 5 is fixedly installed on the top of each lifting rod 4, a slide groove is provided on the adjacent sides of the two positioning blocks 5, a limit block 6 is slidably installed in each slide groove, a reset spring 17 is fixedly installed on the far side of each limit block 6, and the other end of each reset spring 17 is fixedly installed on one side of the slide groove, and a tension sensor 7 for detecting the reset spring 17 is fixedly installed on the far side of each positioning block 5, a screw 16 is rotatably installed in each lifting cylinder 3, and the two lifting rods 4 are respectively sleeved on the surfaces of the two screws 16 and threadedly connected with them.

[0023] During use, the object placement seat 2 is set to place the object to be transported, providing the target position for the robot to transport. The lifting cylinder 3, lifting rod 4, positioning block 5, limiting block 6, return spring 17 and screw 16 are combined to fix the transported object. The positioning block and the limiting block ensure accurate positioning and range control during the lifting process, while the tension sensor 7 for detecting the return spring 17 is used to monitor whether the return spring 17 is reset, and then it can be judged that the limiting block 6 has reached the top of the object. At this time, the robot body 1 controls the screw 16 to stop rotating, thereby completing the fixation of the object and improving the stability of the equipment during the object transportation process.

[0024] In this embodiment, two anti-collision frames 8 are symmetrically and slidably installed at the bottom of the robot body 1. Each anti-collision frame 8 has a U-shaped structure. A plurality of self-locking universal wheels 10 are installed at the bottom of each anti-collision frame 8. Rack bars 9 are fixedly installed on the adjacent sides of the two anti-collision frames 8. The tops of the two rack bars 9 are slidably installed on the bottom of the robot body 1. A connecting rod 11 is fixedly installed on one side of each rack bar 9. The other end of each connecting rod 11 is fixedly installed on one side of the corresponding anti-collision frame 8. Two gears 13 are symmetrically and rotatably installed at the bottom of the robot body 1. A pulley 12 is fixedly installed in the middle of the bottom of each gear 13. A belt 14 is sleeved between the two pulleys 12. The two gears 13 are respectively engaged with the two rack bars 9. A servo motor 15 is fixedly installed at the bottom of the robot body 1. The output end of the servo motor 15 is fixedly installed at the rotation center of the bottom of one of the pulleys 12. The rotation centers of the tops of the two pulleys 12 are fixedly installed at the bottom ends of the two screws 16 through couplings.

[0025] During use, the combination of the anti-collision frame 8, rack bar 9 and self-locking universal wheel 10 is used for the front and rear protection and movement of the robot body 1, and the combination of the gear 13, pulley 12, belt 14 and servo motor 15 is used to provide the power drive for the robot body 1. The servo motor 15 drives the pulley 12 to rotate, and then drives the two gears 13 to rotate simultaneously through the transmission of the belt 14, thereby driving the two screws 16 to rotate, realizing the height adjustment of the lifting rod 4, and enabling the equipment to fix objects of various heights, improving the applicable range of the equipment;

[0026] When the two gears 13 rotate, they can drive the two rack bars 9 to slide in opposite directions, thereby driving the two anti-collision frames 8 to extend towards the farther directions at the front and rear ends of the robot body 1, increasing the support area at the bottom of the equipment and improving the stability of the equipment during transportation. Through synchronous rotation, the extension distance of the anti-collision frame 8 is proportional to the height of the fixed object, ensuring the safety and stability of the transportation process.
