[0036] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0037] like Figures 1 to 7As shown, a lifting and placing mechanism provided by an embodiment of the utility model includes a first lifting assembly 1, a second lifting assembly 5, a material taking assembly 2 and a pallet 3, wherein the material taking assembly 2 and the first lifting assembly 1 are arranged on the pallet 3, and the output end of the first lifting assembly 1 is connected to the material taking assembly 2, which can drive the material taking assembly 2 to move in the vertical direction. The pallet 3 is connected to the second lifting assembly 5, and the second lifting assembly 5 can drive the pallet 3 and the material taking assembly 2 to move up and down, wherein the second lifting assembly 5 can drive the pallet 3 to move up and down, and then drive the material taking assembly 2 and the first lifting assembly 1 on the pallet 3 to move up and down with the pallet 3, and when the material taking assembly 2 takes the material tray 6 from the material box, the second lifting assembly 5 can cooperate with the material taking and feeding of the material trays 6 at different storage heights in the material box.

[0038] The material picking assembly 2 includes a material picking drive, a material picking plate 23, and a material hook block 231 disposed on the material picking plate 23. The output end of the material picking drive is connected to the material picking plate 23. The material picking drive can drive the material hook block 231 on the material picking plate 23 to move horizontally to the first groove 61 or the second groove 62 of the material tray 6. The second groove 62 is located on the side of the first groove 61 away from the support plate 3. The first lifting assembly 1 can drive the material picking assembly 2 to move in the vertical direction, thereby driving the material hook block 231 to be inserted and matched in the first groove 61 or the second groove 62 of the material tray 6.

[0039] When the hook block 231 is located in the first groove 61, the material picking drive can drive the material tray 6 to move out of the material box and to the first position of the pallet 3 through the material picking plate 23. When the hook block 231 is located in the second groove 62, the material picking drive can drive the material tray 6 to move from the first position to the second position of the pallet 3 through the material picking plate 23, thereby transferring the material tray 6 from the material box to the pallet 3.

[0040] Specifically, with the inlet of the material box as a reference, the first groove 61 is arranged on the side of the material tray 6 close to the inlet of the material box, and the second groove 62 is arranged on the side of the material tray 6 away from the inlet of the material box. The material picking drive drives the material picking plate 23 to enter the material box, and the first lifting assembly 1 drives the material picking assembly 2 to move upward, so that the hook block 231 is plugged into the first groove 61. Then, the material picking drive drives the material picking plate 23 to return to its position. Through the cooperation between the hook block 231 and the first groove 61, the material picking plate 23 can drive the material tray 6 to be pulled out of the material box and moved to the first position of the support plate 3. At the first position, the material tray 6 is only partially supported on the support plate 3.

[0041] At this time, the first lifting component 1 drives the material picking component 2 to move downward, so that the hooking block 231 disengages from the first groove 61, and the material picking driving component drives the material picking plate 23 to move, so that the hooking block 231 moves to the second groove 62. The first lifting component 1 drives the material picking component 2 to move upward, so that the hooking block 231 is plugged into the second groove 62, and the material picking driving component drives the material picking plate 23 to continue to return to its position. Through the cooperation between the hooking block 231 and the second groove 62, the material picking plate 23 can drive the material tray 6 to move from the first position of the support plate 3 to the second position of the support plate 3. After moving to the second position, the material tray 6 is completely transferred to the support plate 3, and long-distance hooking is achieved through two hooking.

[0042] The lifting and placing mechanism provided by the embodiment of the utility model drives the picking plate 23 to move in the horizontal direction through the picking drive member, and drives the picking plate 23 to move in the vertical direction by the first lifting component 1, so that the hook block 231 can switch between the first slot 61 and the second slot 62. When the hook block 231 is located in the first slot 61, the picking drive member can drive the material tray to move to the first position to complete the first stroke. When the hook block 231 is located in the second slot 62, the picking drive member can drive the material tray from the first position to the second position to complete the second stroke, so that the picking component 2 can be realized. The long stroke of picking materials is increased, and the moving stroke of the picking plate 23 is increased. At the same time, the first lifting component 1 is set on the support plate 3, and there is no need to increase the size in the horizontal direction to increase the stroke. The overall size of the lifting and placing mechanism will not increase too much, and the space occupied on the AGV smart car will not increase.

[0043] The material taking plate 23 is U-shaped, and two hooking blocks 231 are provided, which are respectively located at the two ends of the U-shaped structure, so that the material tray is subjected to balanced force and will not be skewed when hooking and pulling the material tray.

[0044] In one embodiment, the first lifting assembly 1 includes a first motor 11 and a plurality of guide rods 12, wherein the first motor 11 is disposed at the bottom of the support plate 3, the guide rods 12 pass through the support plate 3 and are connected to the material taking assembly 2, the output end of the first motor 11 is connected to the material taking assembly 2, and the first motor 11 can drive the material taking assembly 2 to move up and down. The guide rods 12 are connected to the material taking assembly 2, and one end of the guide rods 12 away from the material taking assembly 2 passes through the support plate 3. The first motor 11 is a stepping push rod motor, and its output end can extend and retract.

[0045] A plurality of guide sliders 13 are installed on the support plate 3, one end of the guide rod 12 is fixedly installed on the material picking assembly 2, and the other end of the guide rod 12 is slidably connected to the guide slider 13. When the first motor 11 drives the base 25 to move up and down, the guide rod 12 can slide relative to the guide slider 13, thereby guiding the movement of the material picking assembly 2.

[0046] In one embodiment, the material picking drive includes a material picking motor 21, a material picking screw 22 and a material picking transmission assembly 24. The material picking transmission assembly 24 is connected between the output end of the material picking motor 21 and the material picking screw 22. The material picking screw 22 is connected to the material picking plate 23. The material picking motor 21 can drive the material picking plate 23 to move in the horizontal direction through the material picking screw 22. The material picking plate 23 is used to transfer the material tray stored in the material box to the pallet 3 or to send the material tray into the material box.

[0047] Specifically, the material picking motor 21 drives the material picking plate 23 to move toward the material box, and the material picking plate 23 moves into the material box. The first lifting assembly 1 makes the material hook block 231 plug and match with the first slot 61. When the material picking plate 23 returns, it can drive the material tray to be taken out of the material box, so as to transfer the material tray to the first position of the support plate 3. The material hook block 231 is separated from the first slot 61 and then engaged in the second slot 62 through the first lifting assembly 1 and the material picking motor 21. The material picking plate 23 continues to return and drives the material tray to move to the second position, so as to complete the transfer of the material tray from the material box to the support plate 3. When the material tray is sent into the material box, the material hook block 231 is first engaged in the second slot 62. When the material picking motor 21 drives the material picking plate 23 to move from the second position to the first position, the material hook block 231 is separated from the second slot 62 and then engaged in the first slot 61. Under the drive of the material picking motor 21, the material tray can be driven from the first position into the material box through the material picking plate 23, so as to send the material tray into the material box.

[0048] In this embodiment, the picking motor 21 drives the picking screw 22 to rotate, thereby driving the picking plate 23 to move, and the material tray can be pulled out of or pushed into the material box. The picking motor 21, the picking screw 22 and the picking plate 23 are used to pick up and place the material tray. Fewer components are required, and the use of synchronous belts, two synchronous wheels, sliders and other components that result in an increase in the overall size of the picking assembly 2 can be avoided, which can further reduce the space occupied by the lifting and placing mechanism on the AGV smart vehicle.

Among them, the material box is configured to have two material access ports, and the material box is arranged between the two lifting and placing mechanisms, one of which can realize the picking and placing of the material tray through one material access port, and the other lifting and placing mechanism can realize the picking and placing of the material tray through the other material access port.

[0051] In one embodiment, the material taking plate 23 is used as a material bearing tray, and its overall structure is not limited.
