Description

Technical Field

[0001] The utility model relates to the technical field of automatic guided vehicle equipment, in particular to an AGV self-adaptive cargo loading platform. Background Art

[0002] AGV automatic guided vehicles are industrial vehicles that load goods automatically or manually, automatically drive along a set route or pull a cargo trolley to a designated location, and then load and unload goods automatically or manually. With the rapid development of automation and intelligent technology, AGV automatic guided vehicles have been widely used in logistics, manufacturing, warehousing and other industries. AGV trolleys have greatly improved the operating efficiency of these fields with their flexible mobility and efficient handling capabilities.

[0003] Deficiencies of existing technology:

[0004] Currently, common AGV carts are usually composed of main components such as drive systems, navigation systems, cargo platforms and control systems. AGV carts can automatically run according to preset paths to perform tasks such as handling, loading and unloading. However, the cargo platforms of most AGV carts are fixed or have only simple mechanical adjustment and positioning functions, which still have certain defects in actual application. Due to the different weights and sizes of goods, AGV carts often face the problem of unstable center of gravity when transporting goods with large weight or volume, especially when making sharp turns or transporting on uneven roads. This situation is particularly serious. When making sharp turns, the center of gravity of the cargo platform will shift to varying degrees depending on the speed. When passing through uneven roads, due to the shaking during transportation, the position of the goods may move, resulting in the overall center of gravity shifting. Once the center of gravity of the AGV cart shifts, the stability of the AGV cart may decrease, or even a rollover accident may occur, thereby affecting work efficiency and transportation safety.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example

[0033] See also Figure 1-5As shown, the utility model provides a technical solution of an AGV adaptive cargo platform: an AGV adaptive cargo platform, including a driving base 1, a counterweight mechanism 2 is installed on the upper end surface of the driving base 1, a trigger mechanism 3 is movably installed on the upper end of the counterweight mechanism 2, a controller 4 is also installed on the upper end of the counterweight mechanism 2, and a pallet 5 for placing transferred items is fixedly installed on the upper end of the trigger mechanism 3; the counterweight mechanism 2 includes a mounting frame 201, an electromagnet block 202 and a counterweight block 204, the mounting frame 201 is fixedly installed on the upper end surface of the driving base 1, the controller 4 is connected to the upper end of the mounting frame 201, the electromagnet block 202 is centrally fixed inside the mounting frame 201, and permanent magnet blocks 203 are also slidably connected in the cavities on both sides of the mounting frame 201, the counterweight block 204 is installed on the side of the permanent magnet block 203 away from the electromagnet block 202, and counterweight grooves 205 are provided on both sides of the mounting frame 201 to facilitate the horizontal movement of the counterweight block 204. If the overall center of gravity of the AGV is shifted due to factors such as turning or displacement of the goods in the pallet 5 during the transfer process, the trigger mechanism 3 is triggered. After receiving the signal, the controller 4 controls the current of the electromagnet block 202, so that it generates a repulsive force on the permanent magnet block 203 on one side and an attractive force on the permanent magnet block 203 on the other side. The permanent magnet block 203 subjected to the repulsive force drives the counterweight block 204 on one side to move away from the electromagnet block 202 until one end of the counterweight block 204 slides out of the counterweight slot 205. Under the action of the lever, the center of gravity of the AGV is also corrected to a certain extent. Through the counterweight mechanism 2, adaptive adjustment of the AGV with a shifted center of gravity is achieved. By adjusting the positions of the counterweight blocks 204 on both sides, the overall center of gravity of the AGV can be quickly corrected to a certain extent, thereby increasing the turning limit of the AGV and improving the overall work efficiency and transportation safety.

[0034] The trigger mechanism 3 includes a mounting shaft 301, a control rod 303 and a touch switch 305. Both ends of the mounting shaft 301 are rotatably connected to the brackets on both sides of the upper end surface of the mounting frame 201. A balancing platform 302 is fixedly installed on the mounting shaft 301, and the support plate 5 is fixedly installed on the upper end surface of the balancing platform 302. The control rod 303 is threadedly connected to the threaded holes around the balancing platform 302. A compression spring 304 is connected between the lower end of the control rod 303 and the upper end surface of the mounting frame 201. The touch switch 305 is symmetrically installed on both sides of the upper end surface of the mounting frame 201. When the trigger mechanism 3 needs to work, the control rod 303 is rotated first, and the deformation of the compression spring 304 is adjusted by rotating the control rod 303 to make the balancing platform 302 in a horizontal state. Then, the goods are placed in the center on the support plate 5, and then according to the weight of the goods and the trigger sensitivity of the counterweight block 204, the control rod 303 is rotated again. The control rod 303 is rotated to adjust the deformation of the compression spring 304, thereby adjusting the distance between the touch switch 305 and the balance platform 302. During the adjustment process, all control rods 303 should be rotated intermittently in turn. After the rotation is completed, the balance platform 302 should still remain in a horizontal state. When the counterweight block 204 needs to be triggered sensitively, the distance between the touch switch 305 and the balance platform 302 can be reduced. When the counterweight block 204 needs to be triggered slowly, the distance between the touch switch 305 and the balance platform 302 can be increased. Through the trigger mechanism 3, the trigger sensitivity of the counterweight block 204 is flexibly set. This can be achieved by rotating the control rod 303 to adjust the deformation of the compression spring 304. The operation is simple and the adaptability is strong. The entire trigger structure is a simple mechanical structure, which is linked to the tilt state of the AGV car, has a fast trigger response, a low failure rate, and better reliability.

[0035] The controller 4 is electrically connected to the electromagnet block 202 and the touch switch 305 through wires. After receiving the electrical signal from the touch switch 305, the controller 4 first determines the switch position that sends the signal, and then controls the current of the electromagnet block 202 to make the counterweight block 204 slide out of the mounting frame 201 in the opposite direction.

[0036] Buffer pads 6 are installed on both sides of the electromagnet block 202. The buffer pads 6 can play a buffering role when the permanent magnet block 203 and the counterweight block 204 are recovered to avoid rigid collision with the electromagnet block 202.

[0037] The upper end surface inside the mounting frame 201 is symmetrically provided with slide grooves 2011, and the upper ends of the permanent magnet block 203 and the counterweight block 204 are slidably connected to the slide grooves 2011 through sliding bars. The slide grooves 2011 guide the displacement of the permanent magnet block 203 and the counterweight block 204. The lower ends of the permanent magnet block 203 and the counterweight block 204 are provided with several pulleys 7 for reducing friction. The pulleys 7 can reduce the friction between the permanent magnet block 203 and the counterweight block 204 and the mounting frame 201.

[0038] A limit block 8 is installed at the lower end of the counterweight block 204. When the permanent magnet block 203 and the counterweight block 204 move in the direction away from the electromagnet block 202, the limit block 8 can ensure that the upper and lower ends of the counterweight block 204 are limited synchronously after moving into position, thereby avoiding tilting due to uneven force between the upper and lower ends, or even getting stuck in the mounting frame 201.

[0039] The upper end of the control rod 303 is installed with a hexagonal head 9, and the lower end of the control rod 303 is rotatably connected to the compression spring 304 through a mounting hole. When the control rod 303 needs to be rotated, the hexagonal head 9 can be rotated by a hexagonal wrench.

[0040] The working principle of the utility model is as follows:

[0041] When the AGV adaptive cargo platform of this embodiment is in use, if the AGV needs to perform a transfer operation, the control rod 303 is first rotated to adjust the deformation of the compression spring 304 so that the balance platform 302 is in a horizontal state, and then the goods are placed in the center on the pallet 5. Then, according to the weight of the goods and the trigger sensitivity of the counterweight block 204, the control rod 303 is rotated again to adjust the deformation of the compression spring 304, thereby adjusting the distance between the touch switch 305 and the balance platform 302. During the adjustment process, all control rods 303 should be rotated intermittently in turn. After the rotation is completed, the balance platform 302 should still remain in a horizontal state, and then the transfer operation can be carried out. During the cargo transfer process, if the overall center of gravity of the AGV car is offset due to factors such as turning or displacement of the cargo in the pallet 5, the balance platform 302 will tilt to one side to squeeze the compression spring 304 on that side until the lower end of the balance platform 302 touches the touch switch 305. The touch switch 305 is triggered to send a signal to the controller 4. After receiving the signal, the controller 4 first determines the position of the switch that sends the signal, and then controls the current of the electromagnet block 202 to make it The permanent magnet block 203 on the opposite side of the triggered touch switch 305 generates a repulsive force, which generates an attractive force on the permanent magnet block 203 on the other side. The permanent magnet block 203 subjected to the repulsive force drives the counterweight block 204 on one side to move away from the electromagnet block 202 until one end of the counterweight block 204 slides out of the counterweight slot 205. Under the action of the lever, the center of gravity of the AGV trolley is corrected to a certain extent. The utility model has a simple structure and a reasonable design. Through the counterweight mechanism 2, the adaptive adjustment of the AGV trolley with a shifted center of gravity is realized. The position adjustment of the counterweight block 204 allows the overall center of gravity of the AGV to be quickly corrected to a certain extent, increases the turning limit of the AGV, and improves the overall work efficiency and transportation safety. At the same time, through the trigger mechanism 3, the trigger sensitivity of the counterweight block 204 is flexibly set. This can be achieved by rotating the control rod 303 to adjust the deformation of the compression spring 304. The operation is simple and the adaptability is strong. The entire trigger structure is a simple mechanical structure, which is linked to the tilt state of the AGV, has a quick trigger response, a low failure rate, and better reliability.
