Description

Technical Field

[0001] The utility model relates to the technical field of composite robots for cargo transportation, in particular to a composite robot for cargo transportation. Background Art

[0002] A composite robot is a new type of robot that integrates the functions of a mobile robot and an industrial robot. It has "hands, feet, eyes, and brain". Compared with the single functions of AGV / AMR and robotic arms, it combines the characteristics of both and is more flexible, with fast feedback, easy operation, and mobile operation. Composite robots have become key equipment for realizing intelligent industrial production and an important condition for the value competition of robots in the second half of the decade.

[0003] After searching, the applicant found that a Chinese patent disclosed a "multi-functional transport composite mobile robot" with a publication (announcement) number of "CN217837203U". This patent mainly uses a mounting plate to fix four fixed bases on the four corners of the transport vehicle. The auxiliary moving wheels can increase the contact area between the transport vehicle and the ground, and can reduce the occurrence of the transport vehicle rolling over when it collides with people. The plug-in blocks on both sides of the plug-in base are inserted into the inside of the slots on one side of the two fixed bases, and then the fixing plate is connected to the fixed base by bolts. Then, the protective cushions on one side of the four plug-in bases can reduce damage to people when people collide with the transport vehicle, and can also protect the transport vehicle. However, this patent cannot provide cushioning protection for the goods during bumpy transportation, and has poor safety when transporting fragile goods. For this reason, we propose a composite robot for cargo transportation. Utility Model Content

[0004] The purpose of the present utility model is to provide a composite robot for cargo transportation, so as to solve the problems raised in the above background technology that the cargo cannot be cushioned and protected during bumpy transportation and the safety is poor when transporting fragile cargo.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a composite robot for cargo transportation, comprising a loading platform and a buffer mechanism, the buffer mechanism comprising a driving frame, the upper surface of the driving frame being fixedly mounted with buffer members near the four corners, the driving frame being movably connected to a buffer spring via a connecting rod, the buffer spring being movably connected to a movable frame via a sliding sleeve, the movable frame being connected to a first rebound spring and a second rebound spring via a sliding member, and a sliding groove being provided on the upper surface of the driving frame.

[0006] As a preferred solution, a transport box and a robotic arm are fixedly mounted on the upper surface of the loading platform, and a controller is fixedly mounted on the outer wall of the robotic arm.

[0007] As a preferred solution, the bottom of the connecting rod is fixedly installed in the middle position of the upper surface of the driving frame, the buffer spring is sleeved on the outer wall of the connecting rod, the bottom of the buffer spring is fixedly installed on the upper surface of the driving frame, the sliding sleeve is slidably connected to the outer wall of the connecting rod, and the bottom of the sliding sleeve is fixedly connected to the upper end of the buffer spring.

[0008] As a preferred solution, one end of the movable frame is rotatably connected to the rotating member on the outer wall of the sliding sleeve, and the sliding member is rotatably connected to the other end of the movable frame, one end of the first rebound spring is fixedly installed on one side of the sliding member, and the other end of the first rebound spring is fixedly installed on one end of the sliding groove, one end of the second rebound spring is fixedly installed on the other side of the sliding member, and the other end of the second rebound spring is fixedly installed on the other end of the sliding groove, and the first rebound spring and the second rebound spring are both located inside the sliding groove.

[0009] As a preferred solution, an anti-collision mechanism is provided on the outside of the buffer mechanism, and the anti-collision mechanism includes a mounting frame, which is fixedly mounted on the outer wall of the driving frame. A first slot is provided on the upper end of the mounting frame, and a second slot is provided on the front of the mounting frame, and the first slot and the second slot are connected.

[0010] As a preferred solution, two groups of sliding blocks are slidably connected inside the first slot and the second slot, one group of sliding blocks is fixedly mounted with a first anti-collision arc, and the other group of sliding blocks is fixedly mounted with a second anti-collision arc.

[0011] The technical effects and advantages of this utility model are:

[0012] 1. Through the provided buffer mechanism, when the composite robot is used to transport goods, the goods are transported by the drive frame. During transportation, the sliding sleeve slides up and down along the connecting rod, and the buffer spring is subsequently extended and retracted. At the same time, the sliding member at the bottom of the mobile frame slides in the sliding groove, and the first rebound spring and the second rebound spring provide buffering and protection for the entire cargo, thereby preventing damage to fragile goods caused by bumps during transportation. The buffer member protects the loading platform and the drive frame, preventing the entire composite robot from being crushed by excessive weight of the goods, and can well protect fragile goods during transportation;

[0013] 2. Through the anti-collision mechanism, when the composite robot is hit, the first anti-collision arc and the second anti-collision arc are deformed to disperse the impacting object to both sides, avoiding direct impact on the cargo. At the same time, the shape of the arc can change the forward direction of the composite robot and turn it towards an obstacle-free place, preventing the cargo from falling directly due to inertia after the collision, thereby improving the safety of the composite robot's transportation.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 creative efforts are within the scope of protection of the present invention.

[0021] Example 1:

[0022] Please see the attached Figure 1 - Attachment Figure 4, a composite robot for cargo transportation, including a loading platform 1 and a buffer mechanism 4, the buffer mechanism 4 includes a driving frame 401, and buffer members 402 are fixedly installed near the four corners of the upper surface of the driving frame 401, the driving frame 401 is movably connected to a buffer spring 405 through a connecting rod 404, and the buffer spring 405 is movably connected to a moving frame 407 through a sliding sleeve 406, and the moving frame 407 is connected to a first rebound spring 409 and a second rebound spring 410 through a sliding member 408, a sliding groove 403 is provided on the upper surface of the driving frame 401, a transport box 2 and a robotic arm 3 are fixedly installed on the upper surface of the loading platform 1, and a controller 6 is fixedly installed on the outer wall of the robotic arm 3, the bottom of the connecting rod 404 is fixedly installed at the middle position of the upper surface of the driving frame 401, and the buffer spring 405 is sleeved on the connecting rod 404 On the outer wall, the bottom of the buffer spring 405 is fixedly mounted on the upper surface of the driving frame 401, the sliding sleeve 406 is slidably connected to the outer wall of the connecting rod 404, the bottom of the sliding sleeve 406 is fixedly connected to the upper end of the buffer spring 405, one end of the moving frame 407 is rotatably connected to the rotating member on the outer wall of the sliding sleeve 406, and the sliding member 408 is rotatably connected to the other end of the moving frame 407. One end of the first rebound spring 409 is fixedly mounted on one side of the sliding member 408, and the other end of the first rebound spring 409 is fixedly mounted on one end of the sliding groove 403. One end of the second rebound spring 410 is fixedly mounted on the other side of the sliding member 408, and the other end of the second rebound spring 410 is fixedly mounted on the other end of the sliding groove 403. The first rebound spring 409 and the second rebound spring 410 are both located inside the sliding groove 403.

[0023] After the buffer spring 405 is fully compressed by the sliding sleeve 406, the upper end of the sliding sleeve 406 is still higher than the upper end of the connecting rod 404, ensuring that the bottom of the loading platform 1 will not collide with the connecting rod 404. At the same time, when the buffer spring 405 is fully compressed by the sliding sleeve 406, the bottom of the loading platform 1 is against the upper end of the buffer member 402, preventing the driving frame 401 from being damaged by excessive weight of the cargo.

[0024] Specifically, when the composite robot is used to transport goods, the goods are transported by driving the driving frame 401. During transportation, the sliding sleeve 406 slides up and down along the connecting rod 404, and the buffer spring 405 is extended and retracted accordingly. At the same time, the sliding member 408 at the bottom of the mobile frame 407 slides in the sliding groove 403, and is buffered by the first rebound spring 409 and the second rebound spring 410 to provide buffering protection for the entire cargo to avoid damage to the cargo caused by bumps during transportation. The buffer member 402 protects the loading platform 1 and the driving frame 401 to avoid excessive weight of the cargo that damages the entire composite robot, and the cargo can be well protected during transportation.

[0025] Example 2:

[0026] Please see the attached Figure 1 and attached Figure 5 , and on the basis of Example 1, it is further obtained that an anti-collision mechanism 5 is provided on the outside of the buffer mechanism 4, and the anti-collision mechanism 5 includes a mounting frame 501, and the mounting frame 501 is fixedly mounted on the outer wall of the driving frame 401. A first slot 502 is provided at the upper end of the mounting frame 501, and a second slot 503 is provided on the front of the mounting frame 501. The first slot 502 and the second slot 503 are communicated with each other, and two groups of sliding blocks 506 are slidably connected inside the first slot 502 and the second slot 503. A first anti-collision arc 504 is fixedly mounted on one group of sliding blocks 506, and a second anti-collision arc 505 is fixedly mounted on the other group of sliding blocks 506.

[0027] The arc diameter of the first anti-collision arc 504 is smaller than that of the second anti-collision arc, and the middle position of the outer wall of the first anti-collision arc 504 is against the inner wall of the second anti-collision arc 505, so as to avoid the second anti-collision arc 505 being directly broken due to excessive impact force, thereby improving the anti-collision ability of the second arc 505.

[0028] Specifically, when the composite robot is hit, the first anti-collision arc 504 and the second anti-collision arc 505 are deformed to disperse the impacting object to both sides, avoiding direct impact on the cargo. At the same time, the shape of the arc can change the forward direction of the composite robot and turn it toward a place without obstacles, thereby preventing the cargo from falling directly due to inertia after the collision, thereby improving the safety of the composite robot's transportation.

[0029] Working principle of the utility model: The utility model is a composite robot for cargo transportation. The composite robot first loads the cargo into the transport box 2 through the mechanical arm 3, and then drives the cargo toward the target location through the driving frame 401. When bumps occur during transportation, the loading platform 1 presses the sliding sleeve 406 downward, so that the buffer spring 405 is compressed on the connecting rod 404. At the same time, the two ends of the mobile frame 407 rotate on the sliding sleeve 406 and the sliding member 408 respectively, so that the mobile frame 407 slides in the sliding groove 403, and hits the first rebound spring 409 and the second rebound spring back and forth. The spring 410 causes the loading platform 1 to move up and down, cushioning the goods and preventing them from being damaged by bumps. When the composite robot encounters a sudden collision, the impactor will first hit the second anti-collision arc 505. When the second anti-collision arc 505 cannot withstand the impact force, the impact will be transmitted to the first anti-collision arc 504, causing the sliding blocks 506 on the first anti-collision arc 504 and the second anti-collision arc 505 to slide along the first slot 502 and the second slot 503, dispersing the impact force to both sides, and at the same time using inertia to switch the forward direction of the composite robot to the side without obstacles to protect the goods.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
