The support plate 4 can limit the square block 21 at the bottom of the tray body 3 and accommodate the first motor 5. A first motor 5 is fixedly installed on the top of the support plate 4. The output end of the first motor 5 is connected to a fixed gear 6. A double-headed screw rod 7 is rotatably connected to the inside of the support plate 4 through a bearing. After the first motor 5 drives the fixed gear 6 to rotate, it can drive the double-headed screw rod 7 to move through the engagement with the transmission gear 8, so that the double-headed screw rod 7 rotates to adjust the thread of the moving plate 9, and the moving plate 9 moves longitudinally under the limitation of the limiting plate 10. A transmission gear 8 meshing with the fixed gear 6 is connected to the surface of the double-headed screw rod 7. The front side and the rear side of the surface of the double-headed screw rod 7 are both threadedly connected with a moving plate 9. The moving plate 9 can mesh with the surface of the driving gear 13 and can drive the driving gear 13 to rotate around the rotating rod 12 after moving. A limiting plate 10 is connected to the bottom of the moving plate 9. The limiting plate 10 is used to limit the moving plate 9, so that the moving plate 9 moves stably horizontally. The limiting plate 10 is slidably connected to the bottom of the support plate 4. Fixing plates 11 are connected to the front and back of the AGV warehousing robot body 1. The fixing plates 11 can limit the rotating rod 12, so that the rotating rod 12 drives the rotating plate 14 and the driving gear 13 to rotate inside it. A rotating rod 12 is movably connected to the inside of the fixing plate 11. The rotating rod 12 can move inside the fixing plate 11, so that the rotating plate 14 and the driving gear 13 rotate stably. A driving gear 13 is connected to the surface of the rotating rod 12. The driving gear 13 is used to drive the rotating plate 14 to rotate and then drive the clamping block 15 to rotate. A rotating plate 14 located outside the driving gear 13 is connected to the surface of the rotating rod 12. After the rotating plate 14 is rotated by the rotating rod 12, it drives the clamping block 15 to rotate in the inner bayonet 16 at the bottom of the tray body 3. A clamping block 15 is connected to the top of the rotating plate 14. After the clamping block 15 is rotated by the rotating plate 14, it can be stuck in the inner bayonet 16 at the bottom of the tray body 3, so that the tray body 3 is fixed to the support plate 4 at the top of the AGV warehousing robot body 1. The driving gear 13 meshes with the outside of the moving plate 9. An inner bayonet 16 is opened at the bottom of the tray body 3. The inner bayonet 16 is used to limit the clamping block 15, so that the tray body 3 is fixed to the support plate 4. Side limiting members are arranged on both sides of the top of the tray body 3.On the front side and the rear side of the top of the tray body 3, wide limit pieces are provided, so as to facilitate the quick disassembly and assembly of different tray bodies 3 between the AGV storage robot body 1 and the tray body 3 according to production needs.

[0033] Refer to Figures 2-4 As shown in the figure, the side limit piece includes a storage port 171, the storage port 171 is opened on the top of the tray body 3, a placement port 172 is opened on the top of the tray body 3, the placement port 172 can accommodate the reduction motor 173, so that the reduction motor 173 is hidden on the top of the tray body 3 to drive the drive rod 174. A reduction motor 173 is fixedly installed inside the placement port 172. Both sides of the reduction motor 173 are connected with drive rods 174. The reduction motor 173 is used to start the drive rod 174 to rotate the protection plate 175, so that one end of the protection plate 175 moves out of the storage port 171 after rotating from the storage port 171, and rotates to both sides of the goods to block the goods, so that the left and right sides of the goods are limited, preventing the goods from falling from both sides. One end of the drive rod 174 away from the reduction motor 173 extends into the storage port 171, and a protection plate 175 located inside the storage port 171 is connected to the surface of the drive rod 174; the wide limit piece includes an installation box 181, the installation box 181 is used to drive the clamping plate 183 and the stabilizing rod 182 to be installed on the tray body 3, and can be installed by means of additional installation. The installation box 181 is fixedly installed on the top of the tray body 3. An electromagnetic plate 19 is horizontally connected inside the installation box 181, the electromagnetic plate 19 is located at the bottom of the clamping plate 183, a stabilizing block 20 is connected to the inner wall of the installation box 181, the stabilizing block 20 is located outside the clamping plate 183, a stabilizing rod 182 is horizontally movably connected inside the installation box 181, a clamping plate 183 is connected to the surface of the stabilizing rod 182, a torsion spring 184 is sleeved on the surface of the stabilizing rod 182, one end of the torsion spring 184 is connected to the surface of the stabilizing rod 182, and the other end of the torsion spring 184 is connected to the inner wall of the installation box 181. The torsion spring 184 can continuously rotate the stabilizing rod 182 and the clamping plate 183 inside the installation box 181, so that the clamping plate 183 rotates around the stabilizing rod 182 and moves out of the installation box 181 to the top of the tray body 3. After the goods are placed on the top of the tray body 3, the front side and the rear side of the goods can be limited by the clamping plate 183. After one side of the clamping plate 183 moves out from the top of the installation box 181, it can prevent the goods from sliding off the tray body 3 when the AGV storage robot body 1 brakes, so as to prevent the goods on the top of the tray body 3 from falling, and prevent the goods from falling during braking. Both the side limit piece and the wide limit piece are hidden in the tray body 3, which can not affect the daily use of the tray body 3.

[0034] Refer to Figures 1-3, a protective pad 22 is inlaid and connected to the inner side of the protective plate 175. The protective pad 22 is located inside the storage opening 171. The protective pad 22 can buffer during the contact between the protective plate 175 and the goods, preventing the goods from being scratched after the protective plate 175 collides with the goods, and further improving the safety of transporting goods on the top of the tray body 3; a protective pad 23 is inlaid and connected to the inner side of the clamping plate 183. The protective pad 23 is used to protect the goods limited by the clamping plate 183 from being knocked. It prevents the goods from being scratched when contacting the clamping plate 183. The protective pad 23 is located inside the mounting box 181, improving the safety of transporting goods on the top of the tray body 3.

[0035] Working principle: When in use, when the user needs to install the tray body 3 on the AGV storage robot body 1, first insert the square block 21 at the bottom of the tray body 3 into the top of the support plate 4 for preliminary fixation. Then, initially place the inner clamping opening 16 on the top of the clamping block 15. Then start the first motor 5 to drive the fixed gear 6 to rotate, so that the fixed gear 6 meshes with the transmission gear 8 to drive the double-headed screw 7 to rotate, and the two moving plates 9 move under the limitation of the limiting plate 10. The two sides of the moving plate 9 drive the rotating rod 12 and the rotating plate 14 to rotate through meshing with the driving gear 13. After the rotating plate 14 drives the clamping block 15 to rotate inside the inner clamping opening 16, it is clamped in the inner wall of the inner clamping opening 16, fixing the clamping block 15 to the tray body 3, and further fixing the AGV storage robot body 1 to the tray body 3. When disassembling, reverse the above operations to facilitate quickly disassembling and installing different tray bodies 3 between the AGV storage robot body 1 and the tray body 3 according to production needs. When goods are placed on the top of the tray body 3, the reduction motor 173 rotates to drive the drive rod 174 to rotate, so that the drive rod 174 drives the protective plate 175 to rotate out from the inside of the storage opening 171. After the protective plate 175 rotates, it blocks and limits both sides of the goods to prevent them from falling. When the electromagnetic plate 19 is powered off, the clamping plate 183 can drive the stabilizing rod 182 and the clamping plate 183 to rotate back under the elastic torsion of the torsion spring 184. The clamping plate 183 rotates out from the inside of the mounting box 181 and is limited by the stabilizing block 20, so that the height of the clamping plate 183 after rotation is limited, so that it can be magnetically attracted and reset again after the electromagnetic plate 19 is powered on. The clamping plate 183 can limit the front and rear sides of the goods, further limiting the goods to prevent them from falling, so as to achieve the effect of keeping the goods stable during transportation and not easy to fall.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
