DETAILED DESCRIPTION

[0034] 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.

[0035] like Figure 1As shown, a device for docking an AGV trolley with a loading and unloading platform of the present embodiment includes a first docking unit, a second docking unit, a locking structure and a buffer structure. The first docking unit is arranged on the AGV trolley 4, and the second docking unit is arranged on the loading and unloading platform 1. The first docking unit has a plug-in portion, and the second docking unit has a plug-in slot 2 adapted to the plug-in portion. A locking structure is provided between the plug-in portion and the plug-in slot 2, and the locking structure is used to connect and separate the plug-in portion and the plug-in slot 2. A first docking unit and a second docking unit are provided between the AGV trolley 4 and the loading and unloading platform 1. The AGV trolley 4 has a plug-in portion, and the loading and unloading platform 1 has a plug-in slot 2. The locking structure can be used to align, thereby achieving accurate docking, stable connection and separation between the AGV trolley 4 and the loading and unloading platform 1, thereby ensuring efficient material transportation.

[0036] like Figure 2 and Figure 3 As shown, the plug-in portion includes a guide block 5 provided on the side of the AGV trolley 4, and the plug-in slot 2 is provided on the side of the material trolley and is adapted to the guide block 5. The end face edge of the guide block 5 inserted into the plug-in slot 2 is provided with a transition fillet 501. The end face edge of the guide block 5 is provided with a transition fillet 501, which makes the guide block 5 smoother when inserted into the plug-in slot 2, reduces jamming and friction, and improves the efficiency and accuracy of docking. Figure 4 As shown, the guide block 5 is provided with an inner cavity, the length of the guide block 5 is less than the depth of the plug-in slot 2, and the locking structure includes an electromagnet 6 and a magnetic block 7. The electromagnet 6 is provided on the end face of the plug-in slot 2 away from the slot opening. One end of the guide block 5 has a fixed plate 13, and the fixed plate 13 is provided with at least one guide slot. A guide rod 9 is passed through the guide slot. The guide rod 9 is located at one end of the inner cavity and is connected to a baffle 8. The other end of the guide rod 9 extends outside the guide block 5 and is fixedly connected to the magnetic block 7. By providing an inner cavity and a locking structure in the guide block 5, it is ensured that the length of the guide block 5 is less than the depth of the plug-in slot 2 to achieve a reliable connection. When the electromagnet 6 is energized, it can quickly attract the magnetic block 7 to achieve a stable connection between the plug-in portion and the plug-in slot 2, providing safety for material transportation.

[0037] like Figure 5 As shown, the guide block 5 is selected to be flat cylindrical, the fixed plate 13 is disc-shaped and two guide grooves are evenly distributed on the fixed plate 13 to ensure the stability and accuracy of the magnetic block 7 during the movement, and then a guide rod 9 is provided in the guide groove, one end of the guide rod 9 is connected to the baffle 8, and the other end is connected to the magnetic block 7, so that the baffle 8 and the magnetic block 7 are respectively located on both sides of the fixed plate 13, and the magnetic block 7 is also located outside the guide block 5. After the electromagnet 6 is energized, the electromagnet 6 attracts and fixes the magnetic block 7. Since the guide block 5 is displaced along the slot wall of the plug-in slot 2, the locking structure is more reliable, thereby improving the overall performance of the docking device of this embodiment.

[0038] In this embodiment, a buffer structure is further provided between the insertion slot 2 and the insertion portion to reduce the impact force when the guide block 5 is inserted into the insertion slot 2. The buffer structure can effectively reduce the impact force when the guide block 5 is inserted into the insertion slot 2, protecting the device from damage and extending the service life of the device. At the same time, it ensures a smooth docking process and reduces the impact on the material.

[0039] like Figure 4 As shown, the buffer structure includes a first buffer pad 11 provided at the base of the guide block 5 and on the side of the AGV trolley 4, and a second buffer pad 12 provided at the notch of the insertion slot 2. By providing the first buffer pad 11 and the second buffer pad 12 at the base of the guide block 5 and the notch of the insertion slot 2, respectively, the buffering effect is further enhanced, impact forces are absorbed from different positions, and the reliability and stability of the device are improved.

[0040] like Figure 6 As shown, the loading and unloading platform 1 is provided with a control unit, and the electromagnet 6 is electrically connected to the control unit. The control unit is used to control the power on and off of the electromagnet 6 to realize the locking and separation operation of the plug-in part and the plug-in slot 2. During the docking process, the guide block 5 is inserted into the plug-in slot 2 and the plug-in slot 2 has a guiding effect on the guide block 5. When the electromagnet 6 is energized, the magnetic block 7 overcomes the elastic force of the spring 10 and is attracted to the electromagnet 6. At this time, the guide block 5 is fixed in the plug-in slot 2. If the plug-in part needs to be separated, the electromagnet 6 is de-energized, and the electromagnet 6 stops attracting the magnetic block 7. The magnetic block 7 is separated from the electromagnet 6 under the action of the elastic force of the spring 10. At this time, the guide block 5 can be moved out of the plug-in slot 2. By controlling the power on and off of the electromagnet 6 through the control unit, the automated operation of the docking device is realized, which is convenient and fast, and improves work efficiency. At the same time, the connection and separation states can be flexibly controlled according to actual needs.

[0041] In order to avoid interference when the magnetic block 7 enters the plug-in slot 2, the magnetic block 7 is designed to be a circular structure adapted to the inner cavity of the plug-in slot 2 and the magnetic block 7 is arranged in the end face of the guide block 5 formed by the transition fillet 501. The magnetic block 7 is guided by the transition fillet 501 of the guide block 5 to ensure that the magnetic block 7 can be accurately aligned with the electromagnet 6 during the attraction process, thereby improving the locking efficiency and accuracy.
