[0020] The hub stack automatic transfer robot of the present invention will be described below in conjunction with the accompanying drawings.

[0021] In the first embodiment of the present application, Figures 1 to 7 As shown, the wheel hub stack automatic transfer robot (hereinafter referred to as "this patent") includes a wheel hub stack handling component 1, a driving wheel 3, an aiming laser radar 4, a driving observation component 5, an auxiliary steering component 6 and a control console 7. Marking lines are set on the factory floor to facilitate the equipment to find the way. Two front fork arms 2-1 are installed in parallel at both ends of the front of the rear connecting seat 2-3 of the chassis component 2. Driving wheels 3 are installed on the outer sides of the two front fork arms 2-1 through brackets. The two driving wheels 3 are used to provide driving force for this patent, and the independent driving wheels 3 can greatly reduce the turning radius of this patent. The bottom of the rear connecting seat 2-3 A circular groove is provided to install the auxiliary steering assembly 6. The auxiliary steering assembly 6 drives the roller equipped therewith through a built-in driving motor with a clutch. The auxiliary steering assembly 6 can provide a certain driving force. The track 2-2 is fixedly installed on the upper part of the two front fork arms 2-1. A toothed belt 2-21 is provided on the upper surface of the track 2-2. The front surfaces of the two front fork arms 2-1 are respectively installed with an alignment laser radar 4. A groove is provided on the lower surface of the main body 1-2 of the wheel hub stack handling assembly 1 to install the anti-falling assembly 1-25. The track groove 1-26 provided at the lower part of the anti-falling assembly 1-25 is movably connected to the track 2-2. The anti-falling assembly 1- 25 and the track 2-2 can effectively prevent the main body 1-2 from being separated from the chassis assembly 2, so that the present patent can better cope with the wheel hub stack weighing more than 350 kilograms. The main body drive machine 1-24 built into the main body 1-2 engages the toothed belt 2-21 through the gear; the control machine 1-21, the power battery pack 1-22 and the lifting control machine 1-23 are fixedly installed inside the main body 1-2 through the bracket. The communication equipment built into the control machine 1-21 itself can better connect the control information. Two vertical lifting drive tracks 1-1 are fixedly installed on the front surface of the main body 1-2. The lifting drive tracks The driven rollers 1-11 are respectively installed on the upper and lower inner parts of 1-1 through the rotating shaft, and a supporting roller 1-13 is arranged between the two driven rollers 1-11. The lifting control chain 1-12 is connected end to end and rotates on the surfaces of the two driven rollers 1-11 and is supported by the supporting roller 1-13. The motor of the lifting control machine 1-23 controls the lifting control chain 1-12 through the ratchet. The lifting control chain 1-12 drives the fork plate base 1-3 to rise and fall, and the fork plate 1-4 is installed on the front surface of the fork plate base 1-3; the driving observation component 5 is fixedly installed on the top of the lifting drive track 1-1; the driving observation component 5 has built-in laser radar and camera.

[0022] A pallet handling robot with utility model number CN218319283U (hereinafter referred to as "the patent") is limited in weight. The pallet for stacking wheel hubs usually weighs more than 350 kilograms, and the lighter body is difficult to maintain balance during transportation. At the same time, due to its own structural limitations, it can only transport lighter pallets from point A to point B, but cannot directly transport the wheel hubs connected to the pallet to the truck. Therefore, it is not suitable for the production environment of the wheel hub factory. However, due to its heavier structure, the patent can effectively bear the weight of the wheel hub stack, and in conjunction with the lifting drive rail 1-1, the fork plate base 1-3 and the fork plate 1-4, the patent can lift the wheel hub stack to the height of the transport vehicle cargo box, making it convenient for the equipment in the cargo box to load the wheel hub stack.

[0023] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 1 As shown, the hub stack handling assembly 1 is equipped with a control console 7. The staff can stand on the rear connecting seat 2-3 and control the present invention through the control console 7.

[0024] In order to further optimize the working performance of this application, in order to further improve working efficiency and prevent charging from affecting the operation of the equipment, a power battery pack replacement window is opened on the side of the host body 1-2, and the power battery pack 1-22 is installed inside the host body 1-2 through a slide rail and a platform. In order to improve the safety of the battery pack 1-22, a flame retardant cover is provided on the outside of the power battery pack 1-22, and a pressure relief valve is provided. In order to improve the strength of the fork plate 1-4 and the fork plate base 1-3, the surfaces of the fork plate 1-4 and the fork plate base 1-3 are equipped with reinforcing ribs.

[0025] When in use, the wheel stack automatic transfer robot is installed and charged, and then marking lines are set on the factory floor, and the equipment can be put into use.

[0026] When the utility model is in use, the specific operations are as follows:

[0027] When the patent transfers the stacked wheel hubs, the wheel hub stacking station sends a signal to inform the dispatching equipment that there is a stack that needs to be transferred. The driving wheel 3 and the auxiliary steering assembly 6 of the chassis assembly 2 cooperate with each other and arrive in front of the wheel hub stack that needs to be transferred under the guidance of the driving observation assembly 5. Then the aiming laser radar 4 guides the two front fork arms 2-1 to align with the wheel hub stack. The main body driving machine 1-24 of the wheel hub stack handling assembly 1 drives the main body 1-2 to move forward along the track 2-2, allowing the fork plate 1-4 to extend out of the front edge of the front fork arm 2-1. At this time, the fork plate 1-4, which is already in the appropriate position, is inserted into the reserved hole of the wheel hub stack pallet. Then, the lifting control machine 1-23 controls the lifting control chain 1-12 to rotate, allowing the fork plate 1-4 to be lifted to the appropriate position, and the main body driving machine 1-24 drives the main body 1-2 to move along the track 2-2. The wheel hub stack is moved so that the wheel hub stack lifted by the fork plate 1-4 enters between the two front fork arms 2-1. At this time, the patent occupies the smallest space. The driving wheel 3 and the auxiliary steering assembly 6 of the chassis assembly 2 cooperate with each other and reach the yard along the marking line under the guidance of the driving observation assembly 5, and go to the designated position under the command of the dispatching equipment. After arriving at the position, the main engine body driving machine 1-24 drives the main engine body 1-2 to move forward along the track 2-2, and the driving wheel 3 and the auxiliary steering assembly 6 cooperate with each other to adjust the position of the patent so that the wheel hub stack enters the placement position. After the wheel hub stack is positioned, the lifting control machine 1-23 controls the lifting control chain 1-12 to rotate, so that the chain 1-12 controls the fork plate base 1-3 to lower the fork plate 1-4 to the ground, and the main engine body driving machine 1-24 drives the main engine body 1-2 to reset along the track 2-2 to complete a transfer. When the wheel hub stack needs to be transported to the cargo box of the transport vehicle, other working methods are the same, only the chain 1-12 controls the fork plate base 1-3 to lower the fork plate 1-4 to the ground and then lifts it to the cargo box height, the active wheel 3 drives the patent to continue forward, and then the chain 1-12 controls the fork plate base 1-3 to lower the fork plate 1-4 to the bottom plate of the cargo box, and the wheel hub stack loading is completed.

[0028] In summary, the wheel stack automatic transfer robot of the utility model embodiment effectively controls the overall volume through the wheel stack handling component 1 that can move back and forth on the chassis component 2, and cooperates with the independent driving wheel 3 and the auxiliary steering component 6, so that the device can turn with an extremely small radius, allowing the device to move freely in a smaller space. At the same time, with the help of the alignment laser radar 4, the device can be aligned with the wheel stack more quickly, thereby completing rapid loading and unloading, and the driving observation component 5 ensures that the equipment can sense obstacles in time, and decide to stop or continue to move forward according to actual conditions. It can automatically transfer the wheel stack in the factory to the cargo yard or load the wheel stack in the cargo yard onto a truck, which can effectively improve logistics efficiency and improve the overall work efficiency of the cargo yard.

Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
