Description

Technical Field

[0001] The utility model relates to the technical field of transport robots, in particular to a roller transport robot which is easy to move. Background Art

[0002] Handling robots, industrial robots capable of automated handling operations, are a high-tech advancement in modern automatic control, incorporating disciplines such as mechanics, mechanical engineering, electrical hydraulics and pneumatics, automatic control, sensor technology, single-chip microcomputers, and computer technology. They have become a crucial component of modern mechanical manufacturing systems. Their advantages include being able to be programmed to perform a variety of tasks, combining the strengths of both humans and machines in their structure and performance, and particularly embodying artificial intelligence and adaptability.

[0003] With the rapid development of industrial automation, handling robots have penetrated deeply into various handling tasks with their high efficiency, precision and labor-saving characteristics. However, when we face special handling objects such as large rollers, the handling process becomes particularly complicated and difficult due to the large size, heavy weight and smooth surface of large rollers. During transportation, due to inertia, these rollers are very likely to roll, causing the rollers to easily slip from the handling robot, and then cause damage to the rollers themselves, and are more likely to pose a serious safety threat to nearby workers. Although some existing roller limiting devices can limit the rollers during the handling process, these limiting devices can often only limit rollers of a single size and cannot flexibly limit rollers of different sizes.

[0004] Chinese patent document CN216231942U discloses a transport robot that is easy to move, comprising a base plate, a load-bearing seat fixedly connected to the top outer wall of the base plate, a placement groove formed on the top outer wall of the load-bearing seat, an anti-slip pad fixedly connected to the inner wall of the placement groove, a positioning plate fixedly connected to the inner wall of one side of the placement groove, symmetrical guide rails formed on both sides of the top of the load-bearing seat, and a clamping plate slidably connected to the inner walls of the two guide rails, and sponge pads fixedly connected to the outer walls on the opposite sides of the clamping plate and the positioning plate; however, the following defects still exist during implementation:

[0005] Although the device in the above-mentioned document can provide stable support through the base plate and the load-bearing seat, so that the base plate and the load-bearing seat will not shake during unloading, which provides convenience for the unloading process, the device in the above-mentioned document cannot limit the position of the roller when transporting larger rollers, which can easily cause the rollers to roll during transportation and then collide with each other, thereby easily causing damage to the rollers themselves and more likely posing a serious safety threat to nearby workers.

When the grabbing assembly 7 moves to the position of and, the hydraulic cylinder 71 drives the connecting block 72 and the mechanical claw assembly 73 to move downward, and the grabbed roller is placed between the two clamping blocks 43.

[0045] Example 4

[0046] like Figure 3-5 As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, the clamping block 43 is arranged in an arc shape, and the clamping block 43 is made of rubber material. The second limiting component 3 includes a support plate 31, the lower end of the support plate 31 is fixedly connected to the upper end of the motor moving vehicle 1, and a plurality of sliding grooves 32 are opened in the middle of the support plate 31.

Then, under the elastic force of the spring 42 itself, the spring 42 will be driven to extend, and then the clamping blocks 43 will be pushed to move toward the roller, so that the inner cavity of the clamping blocks 43 can fit closely with the outer surface of the roller, thereby limiting the position of the roller. Then, the staff rotates the threaded rod -34, and then drives the slider -33 to move in the inner cavity of the slide groove 32, so that the slider -33 can be used to limit the end face position of the roller to prevent the roller from rolling during the transportation process of the roller, and then causing several rollers to collide with each other, thereby causing damage to the roller itself, or an accident occurs during the transportation process, causing the roller to detach from the device, thereby causing damage to the roller, and then repeat the above steps to place several rollers on the device in turn, and finally control the motor moving vehicle 1 to run through the controller, and then drive the device to move, so that several rollers can be transported.

[0048] The following is a detailed description of the working principle of this easy-to-move roller handling robot.

[0049] like Figure 1-9 As shown, when the roller needs to be transported, first, the roller needs to be grabbed and transported to the first limit assembly 4, and the device is first moved to the vicinity of the roller that needs to be transported. Then, the controller controls the operation of the motor 2 8, and the output end of the motor 2 8 drives one of the threaded rods 2 63 to rotate. Then, with the cooperation of the pulley 9 and the belt 10, the other threaded rod 2 63 is driven to rotate. Therefore, with the cooperation of the two threaded rods 2 63, the slider 2 621 is driven to slide in the inner cavity of the guide rail block 61. Then, with the cooperation of the two sliders 2 621, the support block 62 is driven to move, and then the grabbing assembly 7 is driven to move above the roller through the support block 62.

[0050] Then, it is necessary to grasp and convey the roller through the grab assembly 7, and the controller controls the motor 1 732 to operate, and uses the output end of the motor 1 732 to drive the threaded rod 3 733 to rotate, and then the threaded rod 3 733 is threadedly connected to the claw hand 734, so as to drive the claw hand 734 to expand, and then the controller controls the hydraulic cylinder 71 to operate, and then uses the telescopic rod of the hydraulic cylinder 71 to drive the connecting block 72 to move toward the roller, and then under the action of the connecting block 72, it will drive the mechanical claw assembly 73 to move toward the roller. When the mechanical claw assembly 73 moves to a suitable height, the controller controls the motor 1 732 to operate, and the output end of the motor 1 732 rotates in the opposite direction, and then Then, the motor 1 732 drives the threaded rod 3 733 to rotate in the opposite direction, thereby driving the claw hand 734 to retract, and then the roller can be grabbed by the cooperation of the two claw hands 734, and then the hydraulic cylinder 71 is controlled by the controller to operate, and the hydraulic cylinder 71 is used to drive the connecting block 72 and the mechanical claw assembly 73 to move upward, and then the motor 2 8 is controlled by the controller to operate, so that the output end of the motor 2 8 rotates in the opposite direction, driving the threaded rod 2 63 to rotate in the opposite direction, and then driving the moving assembly 6 and the grabbing assembly 7 to move. When the grabbing assembly 7 moves to the position of and, the hydraulic cylinder 71 drives the connecting block 72 and the mechanical claw assembly 73 to move downward, and the grabbed roller is placed between the two clamping blocks 43;

[0051] Then the roller needs to be limited. When the mechanical claw assembly 73 places the roller between the two clamping blocks 43, the roller will apply a force with the two clamping blocks 43, driving the clamping blocks 43 to move away from the roller. Then the clamping blocks 43 will apply a force to the spring 42, driving the spring 42 to contract. Then, under the elastic force of the spring 42 itself, the spring 42 will extend, and then push the clamping blocks 43 to move toward the roller, so that the inner cavity of the clamping blocks 43 can fit tightly with the outer surface of the roller, thereby limiting the position of the roller. Then the staff rotates the threaded rod 34 , and then drives the slider 1 33 to move in the inner cavity of the slide groove 32, so that the slider 1 33 can be used to limit the end face position of the roller to prevent the roller from rolling during the transportation process of the roller, and then causing several rollers to collide with each other, thereby causing damage to the roller itself, or an accident occurs during the transportation process, causing the roller to detach from the device, thereby causing damage to the roller, and then repeat the above steps to place several rollers on the device in turn, and finally control the motor moving vehicle 1 to run through the controller, and then drive the device to move, so that several rollers can be transported.

[0052] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
