Description

Technical Field

[0001] The utility model relates to the technical field of AGV robots, in particular to an AGV robot convenient for loading and unloading goods. Background Technique

[0002] An AGV robot, that is, an automatic guided vehicle, is a robot capable of automatic guiding and moving. They track ground marks through vision, magnetic navigation, laser or other means to achieve functions such as automatic navigation, movement, multi-sensor control, and network interaction. AGV robots achieve various tasks by receiving and interpreting built-in computer code instructions, including transporting materials, assembling parts, warehouse management, etc. They use different navigation methods, such as magnetic strip guidance, laser guidance, RFID guidance, etc., to automatically transport items to designated locations. During the process of using an AGV robot to transport materials, generally, workers carry the materials onto the AGV robot, and then the AGV robot transports the materials to the designated area.

[0003] In view of the above related technologies, the inventor found that some materials are heavy, and the material carrying platform of the AGV robot has a certain height. Workers need to lift the materials to a relatively high height before placing them on the carrying platform, which increases the labor intensity of the workers, reduces the work efficiency, and when the materials are placed on the carrying platform, due to the large friction between the materials and the carrying platform, a relatively large force is required to move the materials to the middle position of the carrying platform, reducing the convenience of operation. Content of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide an AGV robot convenient for loading and unloading goods, which reduces the labor intensity, improves the work efficiency and the convenience of operation.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide an AGV robot convenient for loading and unloading goods, including: two AGV robot bodies, a horizontal carrying frame is arranged between the two AGV robot bodies, and a lifting drive mechanism connected to the two AGV robot bodies is further included. The lifting drive mechanism is connected to the horizontal carrying frame and is adapted to drive the horizontal carrying frame to move in the vertical direction. The two AGV robots are indirectly connected in the horizontal direction through the lifting drive mechanism and the horizontal carrying frame;

[0006] The horizontal carrying frame includes a carrying frame body, and a number of rectangular cavities are arranged at intervals on the carrying frame body. Auxiliary roller assemblies are respectively arranged in the rectangular cavities. The lifting drive mechanism drives the horizontal carrying frame to contact the ground. The top of the outer circle of the auxiliary roller assembly is higher than the upper plane of the carrying frame body. After the lifting drive mechanism drives the horizontal carrying frame to leave the ground, the top of the outer circle of the auxiliary roller assembly is lower than the upper plane of the carrying frame body.

[0007] By adopting the above technical solution, during use, the lifting drive mechanism is operated to drive the horizontal bearing frame to move downward and contact the ground, thereby reducing the height of the horizontal bearing frame, facilitating the workers to place the materials on the horizontal bearing frame, reducing the labor intensity of the workers, and improving the work efficiency. Since the horizontal bearing frame contacts the ground, the top of the outer circle of the auxiliary roller assembly in the rectangular cavity is higher than the upper plane of the bearing frame body. The auxiliary roller assembly is in rolling connection with the bottom plane of the material, and with a relatively small force, the material can be pushed to move to the middle position of the horizontal bearing frame, enhancing the force balance of the horizontal bearing frame and improving the convenience of operation. After the work of placing the materials on the horizontal bearing frame is completed, the lifting drive mechanism is operated to drive the horizontal bearing frame to move upward. Under the action of its own gravity and the gravity of the material, the auxiliary roller assembly moves downward relative to the bearing frame body, enabling the material to be stably placed on the upper plane of the bearing frame body. Since the two AGV robots are indirectly connected in the horizontal direction through the lifting drive mechanism and the horizontal bearing frame, wherein, when one AGV robot body works, it drives the other AGV robot body as a follower to move to the designated area through the lifting drive mechanism and the horizontal bearing frame.

[0008] In a preferred example of the present utility model, it can be further configured that: the lifting drive mechanism includes a lifting drive assembly respectively connected to the AGV robot body. The lifting drive assembly includes an electric push rod, the upper end of the electric push rod is connected with a fixing plate, the fixing plate is connected with the AGV robot body, the extending end of the electric push rod is connected with the horizontal bearing frame, and guiding members are respectively arranged on both sides of the electric push rod.

[0009] By adopting the above technical solution, the telescopic rod of the electric push rod makes extending and contracting movements, thereby driving the horizontal bearing frame to move in the vertical direction. Through the use of the guiding members, the stability of the horizontal bearing frame during movement is enhanced, and the AGV robot body is indirectly connected with the bearing frame body in the horizontal direction through the guiding members, that is, when the AGV robot body works, it drives the bearing frame body to move through the guiding members.

[0010] In a preferred example of the present utility model, it can be further configured that: the guiding member includes a T-shaped groove arranged at the end of the bearing frame body, a T-shaped guide rail is arranged in the T-shaped groove, the T-shaped guide rail is connected with the AGV robot body, a T-shaped sliding seat is sleeved on the T-shaped guide rail, and the T-shaped sliding seat is respectively connected with the AGV robot body and the bearing frame body.

[0011] By adopting the above technical solution, since the T-shaped guide rail is arranged in the T-shaped groove at the end of the carrier frame body and is connected to the AGV robot body, the carrier frame body can be lifted smoothly. At the same time, the AGV robot body can indirectly pull the carrier frame body to move through the T-shaped guide rail. When the carrier frame body contacts the ground, the T-shaped guide rail is located in the inner cavity of the T-shaped sliding seat. During the process of the lifting drive mechanism driving the carrier frame body to move upward, the T-shaped guide rail can smoothly enter the T-shaped groove.

[0012] In a preferred example of the present utility model, it can be further configured that: V-shaped cavities are respectively arranged on the front and rear sides of the carrier frame body. Guide rollers are arranged in the V-shaped cavities. Both ends of the guide rollers are respectively inserted through the carrier frame body and are rotatably connected thereto. The top of the outer circle of the guide rollers is flush with the upper plane of the carrier frame body.

[0013] By adopting the above technical solution, by arranging the guide rollers in the V-shaped cavities, after the materials contact the guide rollers, the guide rollers can guide the materials to slide smoothly onto the auxiliary roller assembly, improving the convenience of operation.

[0014] In a preferred example of the present utility model, it can be further configured that: the auxiliary roller assembly includes an auxiliary roller and sliding support seat members rotatably connected to both ends thereof. The sliding support seat members include C-shaped sliding seats and support seat bodies sliding in their inner cavities. The support seat bodies are rotatably connected to the ends of the auxiliary rollers. A limiting plate is connected to the upper end of the support seat body. The limiting plate contacts the top of the C-shaped sliding seat. The lower end of the support seat body extends below the C-shaped sliding seat. The C-shaped sliding seat is connected to the carrier frame body.

[0015] By adopting the above technical solution, when the lifting drive mechanism works to drive the horizontal carrier frame to move downward, the bottom of the sliding support seat member on the horizontal carrier frame first contacts the ground. The lifting drive mechanism continues to drive the horizontal carrier frame to move downward, so that the lower plane of the carrier frame body contacts the ground, that is, the top of the outer circle of the auxiliary roller is higher than the upper plane of the carrier frame body, facilitating the rolling contact between the auxiliary roller and the bottom plane of the materials, reducing the resistance to the movement of the materials. When the lifting drive mechanism works to drive the horizontal carrier frame to move upward, under the combined action of the self-weight of the auxiliary roller and the weight of the materials, the auxiliary roller moves downward relative to the carrier frame body, and the materials fall smoothly onto the carrier frame body.

[0016] In a preferred example of the present utility model, it can be further configured that: a buffer cushion plate is connected to the lower end of the support seat body.

[0017] By adopting the above technical solution, through the setting of the buffer cushion plate, the support seat body is in buffered contact with the ground, playing a protective effect on the ground.

[0018] In summary, the utility model includes at least one of the following beneficial technical effects:

[0019] 1. The lifting drive mechanism works to drive the horizontal carrier to contact the ground, reducing the height of the horizontal carrier, facilitating workers to place materials on the horizontal carrier, reducing labor intensity, and improving work efficiency.

[0028] The following describes the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present invention, and are not used to limit the present utility model.

[0029] It should be noted that these attached drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic way. Therefore, they only show the components related to the present utility model.

[0030] Referring to Figures 1-2 , an AGV robot for facilitating the loading and unloading of goods disclosed by the present utility model includes: two AGV robot bodies 1. A horizontal bearing frame 20 is provided between the two AGV robot bodies 1. It further includes a lifting drive mechanism connected to the two AGV robot bodies 1. The lifting drive mechanism is connected to the horizontal bearing frame 20 and is adapted to drive the horizontal bearing frame 20 to move in the vertical direction. The two AGV robots are indirectly connected in the horizontal direction through the lifting drive mechanism and the horizontal bearing frame 20. When one AGV robot body 1 works, it drives the other AGV robot body 1 as a follower to move to a designated area through the lifting drive mechanism and the horizontal bearing frame 20.

[0031] The horizontal bearing frame 20 includes a bearing frame body 21. A number of rectangular cavities 22 are provided at intervals on the bearing frame body 21. Auxiliary roller assemblies 30 are respectively arranged in the rectangular cavities 22. The lifting drive mechanism drives the horizontal bearing frame 20 to contact the ground. The top of the outer circle of the auxiliary roller assembly 30 is higher than the upper plane of the bearing frame body 21. After the lifting drive mechanism drives the horizontal bearing frame 20 to leave the ground, the top of the outer circle of the auxiliary roller assembly 30 is lower than the upper plane of the bearing frame body 21.

[0032] The auxiliary roller assembly 30 includes an auxiliary roller 31 and sliding support seat members 32 rotatably connected to both ends thereof. The sliding support seat member 32 includes a C-shaped sliding seat 321 and a support seat body 322 sliding in its inner cavity. The support seat body 322 is rotatably connected to the end of the auxiliary roller 31. The upper end of the support seat body 322 is connected with a limit plate 323. The limit plate 323 contacts the top of the C-shaped sliding seat 321. The limit plate 323 prevents the support seat body 322 from disengaging from the inner cavity of the C-shaped sliding seat 321. The lower end of the support seat body 322 extends below the C-shaped sliding seat 321. The C-shaped sliding seat 321 is connected with the bearing frame body 21. When the lifting drive mechanism works to drive the horizontal bearing frame 20 to move downward, the bottom of the sliding support seat member 32 on the horizontal bearing frame 20 first contacts the ground. The lifting drive mechanism continues to drive the horizontal bearing frame 20 to move downward, so that the lower plane of the bearing frame body 21 contacts the ground, that is, the top of the outer circle of the auxiliary roller 31 is higher than the upper plane of the bearing frame body 21, which is convenient for the outer circle of the auxiliary roller 31 to rollingly contact the bottom plane of the material, reducing the resistance of the material movement. When the lifting drive mechanism works to drive the horizontal bearing frame 20 to move upward, under the combined action of the self-gravity of the auxiliary roller 31 and the gravity of the material, the auxiliary roller 31 moves downward relative to the bearing frame body 21, and the material smoothly falls on the bearing frame body 21.

[0033] A buffer backing plate 5 is connected to the lower end of the support seat body 322; the buffer backing plate 5 is made of a rubber plate. Through the arrangement of the buffer backing plate 5, the support seat body 322 is in buffered contact with the ground, achieving a protective effect on the ground.

[0034] The lifting drive mechanism includes a lifting drive assembly 40 respectively connected to the AGV robot body 1. The lifting drive assembly 40 includes an electric push rod 41. The upper end of the electric push rod 41 is connected to a fixing plate 42. The fixing plate 42 is connected to the AGV robot body 1. The extending end of the electric push rod 41 is connected to the horizontal carrier 20. Guide members 43 are respectively arranged on both sides of the electric push rod 41; the telescopic rod of the electric push rod 41 makes extending and contracting movements, thereby driving the horizontal carrier 20 to move in the vertical direction. Through the use of the guide members 43, the stability of the horizontal carrier 20 during movement is enhanced. Moreover, the AGV robot body 1 is indirectly connected to the carrier body 21 in the horizontal direction through the guide members 43, that is, when the AGV robot body 1 works, it drives the carrier body 21 to move through the guide members 43.

[0035] The guide member 43 includes a T-shaped groove 431 arranged at the end of the carrier body 21. A T-shaped guide rail 432 is arranged in the T-shaped groove 431. The T-shaped guide rail 432 is connected to the AGV robot body 1. A T-shaped sliding seat 433 is sleeved on the T-shaped guide rail 432. The T-shaped sliding seat 433 is respectively connected to the AGV robot body 1 and the carrier body 21; since the T-shaped guide rail 432 is arranged in the T-shaped groove 431 at the end of the carrier body 21 and the T-shaped guide rail 432 is connected to the AGV robot body 1, the carrier body 21 can be lifted smoothly. At the same time, the AGV robot body 1 can indirectly pull the carrier body 21 to move through the T-shaped guide rail 432. When the carrier body 21 contacts the ground, the T-shaped guide rail 432 is located in the inner cavity of the T-shaped sliding seat 433. During the process of the lifting drive mechanism driving the carrier body 21 to move upward, the T-shaped guide rail 432 can smoothly enter the T-shaped groove 431.

[0036] V-shaped cavities 6 are respectively arranged on the front and rear sides of the carrier body 21. Guide rollers 7 are arranged in the V-shaped cavities 6. Both ends of the guide rollers 7 respectively pass through the carrier body 21 and are rotatably connected thereto. The top of the outer circle of the guide rollers 7 is flush with the upper plane of the carrier body 21; by arranging the guide rollers 7 in the V-shaped cavities 6, after the material contacts the guide rollers 7, the guide rollers 7 can guide the material to slide smoothly onto the auxiliary roller assembly 30, improving the convenience of operation.

[0037] The implementation principle of this embodiment is as follows: during use, the lifting drive mechanism is operated to drive the horizontal carrier 20 to move downward and contact the ground, thereby reducing the height of the horizontal carrier 20, facilitating workers to place materials on the horizontal carrier 20, reducing the labor intensity of workers, and improving work efficiency. Since the horizontal carrier 20 contacts the ground, the top of the outer circle of the auxiliary roller assembly 30 in the rectangular cavity 22 is higher than the upper plane of the carrier body 21. The auxiliary roller assembly 30 is in rolling connection with the bottom plane of the material, and a relatively small force can be used to push the material to move it to the middle position of the horizontal carrier 20, enhancing the force balance of the horizontal carrier 20 and improving the convenience of operation. After the work of placing the material on the horizontal carrier 20 is completed, the lifting drive mechanism is operated to drive the horizontal carrier 20 to move upward. The auxiliary roller assembly 30 moves downward relative to the carrier body 21 under the action of its own gravity and the gravity of the material, so that the material is stably placed on the upper plane of the carrier body 21. Since the two AGV robots are indirectly connected in the horizontal direction through the lifting drive mechanism and the horizontal carrier 20, wherein, one AGV robot body 1 drives the other AGV robot body 1 as a follower to move to a designated area through the lifting drive mechanism and the horizontal carrier 20 during operation.
