[0018] The embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings.

[0019] Figures 1 to 4 Shown is a schematic structural diagram of the utility model.

[0020] The accompanying drawings are marked as follows: active synchronous wheel 1, hook limit block 2, first fixed synchronous wheel 3, in-position sensor 4, hook drive plate 5, synchronous block 6, first spring fixed block 7, telescopic spring 8, third follower synchronous wheel 9, second spring fixed block 10, telescopic limit block 11, first follower synchronous wheel 12, second follower synchronous wheel 13, second fixed synchronous wheel 14, third fixed synchronous wheel 15, limit portion 16, telescopic plate 17, hook guide rail 18, synchronous belt 19, guide mounting plate 20, mounting plate 21, telescopic guide rail 22, rotating chain 23, rotating gear 24, fixed bottom plate 25, rotating stepping motor 26, telescopic stepping motor 27, hook assembly 28, push frame 29, hook mounting plate 30, hook fixing plate 31, hook portion 32, bearing 33.

[0021] The utility model of the AGV with the function of hooking materials includes a mounting plate 21, a telescopic stepper motor 27, a synchronous belt 19, a telescopic spring 8, a telescopic plate 17, and a hooking assembly 28. When the trolley picks up materials, the telescopic stepper motor 27 drives the hooking assembly 28 to move forward through the synchronous belt 19. After the hooking assembly 28 moves, the telescopic spring 8 pulls the telescopic plate 17 and the hooking assembly 28 to move in the same direction. The telescopic plate 17 stops after touching the shelf, and the hooking assembly 28 continues to move forward until the hooking assembly 28 hooks the material box. When retracting, the telescopic stepper motor 27 reverses to drive the hooking assembly 28 to retract. After the push frame 29 of the hooking assembly 28 touches the limit part 16 of the telescopic plate 17, the hooking assembly 28 drives the telescopic plate 17 to retract back to the original position together, and the in-position sensor 4 sends a signal, and the telescopic stepper motor 27 stops running, completing the material picking function.

[0022] like Figure 4 The hook assembly 28 shown includes a hook fixing plate 31, a hook mounting plate 30, a push frame 29, and a hook portion 32. The hook fixing plate 31 is fixedly connected to the hook mounting plate 30, and the rear end of the hook mounting plate 30 is fixedly connected to the push frame 29. The hook portion 32 is an L-shaped long plate protruding from the lower part of the hook fixing block 31. When taking materials, the material box is hooked up by the hook portion 32 to drive the material box to move, and the material box is placed on the telescopic plate 17.

[0023] like Figures 1 to 3 As shown, two telescopic guide rails 22 are respectively installed in parallel on both sides of the mounting plate 21. The telescopic plate 17 is slidably installed on the telescopic guide rails 22 through the guide mounting plate 20. Installing the telescopic plate 17 through the guide mounting plate 20 can increase the installation space between the telescopic plate 17 and the mounting plate 21.

[0024] A hook guide rail 18 is provided below the telescopic plate 17 .

[0025] The telescopic stepping motor 27 is installed at the rear end of the mounting plate 21 and is located on one side of the hook guide track 18. The telescopic stepping motor 27 is equipped with a driving synchronous wheel 1 through a power output shaft. The mounting plate 21 is fixedly equipped with a first fixed synchronous wheel 3, a second fixed synchronous wheel 14 and a third fixed synchronous wheel 15. The first fixed synchronous wheel 3 is located at the rear end of the mounting plate 21 and on the other side of the hook guide track 18. The second fixed synchronous wheel 14 is located at the front end of the mounting plate 21 and on the same side as the telescopic stepping motor 27. The third fixed synchronous wheel 15 is located between the telescopic stepping motor 27 and the second fixed synchronous wheel 14 and close to the telescopic stepping motor 27.

[0026] The first follower synchronous wheel 12, the second follower synchronous wheel 13 and the third follower synchronous wheel 9 are installed below the telescopic plate 17. When the telescopic plate 17 is in the initial position, the first follower synchronous wheel 12 is located at the front end of the hook guide track 18 and on the same side as the first fixed synchronous wheel 3, and the first follower synchronous wheel 12 and the first fixed synchronous wheel 3 have the same lateral distance to the hook guide track 18. The second follower synchronous wheel 13 is located at the front end of the hook guide track 18 and on the same side as the telescopic stepping motor 27. The third follower synchronous wheel 9 is located in the middle of the second fixed synchronous wheel 14 and the telescopic stepping motor 27 in the longitudinal direction, and in the middle of the second fixed synchronous wheel 14 and the second follower synchronous wheel 13 in the lateral direction.

[0027] The synchronous belt 19 passes through the active synchronous wheel 1, the first fixed synchronous wheel 3, the first follower synchronous wheel 12, the second follower synchronous wheel 13, the third follower synchronous wheel 9, the second fixed synchronous wheel 14, the third fixed synchronous wheel 15 in sequence and finally returns to the active synchronous wheel 1, and the synchronous belt 19 is driven to move by the power output shaft of the telescopic stepping motor 27.

[0028] When the telescopic plate 17 is extended, the first follower synchronous wheel 12, the second follower synchronous wheel 13 and the third follower synchronous wheel 9 are driven to move, and the distance between the third follower synchronous wheel 9 and the second fixed synchronous wheel 14 is reduced; the distance between the first follower synchronous wheel 12 and the first fixed synchronous wheel 3 is lengthened, so that the hook assembly 28 has a sufficient moving distance.

[0029] When the telescopic plate 17 is retracted, the first follower synchronous wheel 12, the second follower synchronous wheel 13 and the third follower synchronous wheel 9 are driven to move, and the distance between the third follower synchronous wheel 9 and the second fixed synchronous wheel 14 increases; the distance between the first follower synchronous wheel 12 and the first fixed synchronous wheel 3 decreases.

[0030] The hook guide rail 18 is slidably provided with a hook drive plate 5. A synchronous block 6 is provided on the synchronous belt 19 between the first follower synchronous wheel 12 and the first fixed synchronous wheel 3, and the hook drive plate 5 is fixedly connected to the synchronous block 6. The movement of the synchronous belt 19 can drive the hook drive plate 5 to move. The initial position of the hook drive plate 5 matches the hook limit block 2 at the rear end of the hook guide rail 18 at the rear end of the mounting plate 21.

[0031] The limiting part 16 is a plate body protruding from the rear of the telescopic plate 17. The telescopic plate 17 has two hollow long grooves, which correspond to the sliders of the hook guide rail 18. The hook assembly 28 is located above the telescopic plate 17. The push frame 29 of the hook assembly 28 cooperates with the limiting part 16 of the telescopic plate 17. The hook assembly 28 passes through the long groove and is slidably connected to the hook guide rail 18. When the hook assembly 28 slides, the hook driving plate 5 drives the hook assembly 28 to slide together. When the hook assembly 28 is in place, the push frame 29 of the hook assembly 28 limits the sliding of the telescopic plate 17 through the limiting part 16.

[0032] The rear end of the mounting plate 21 is provided with an in-position sensor 4 for sensing whether the telescopic plate 17 returns to its original position.

[0033] The mounting plate 21 is provided with a second spring fixing block 10, and the bottom surface of the telescopic plate 17 is provided with a first spring fixing block 7. One end of the telescopic spring 8 is fixed on the first spring fixing block 7, and the other end is fixed on the second spring fixing block 10. In the initial state, the telescopic spring 8 is in the longest stretched state.

[0034] When the hook assembly 28 slides forward, the limit portion 16 of the telescopic plate 17 is not limited by the resistance of the push frame 29, and the telescopic spring 8 contracts to drive the telescopic plate 17 to move forward. After the telescopic plate 17 hits the shelf, the telescopic spring 8 stops contracting, the telescopic plate 17 stops moving, and the telescopic plate 17 is seamlessly connected to the shelf, which facilitates the material box to move from the shelf to the telescopic plate 17. The hook assembly 28 continues to slide to reach the set distance. After the hook assembly 28 is located in front of the material box, the material box is hooked by the hook portion 32. When the hook assembly 28 is recovered, the telescopic stepping motor 27 is reversed, and the hook assembly 28 drives the material box to retreat together, so that the material box is completely placed on the telescopic plate 17. After the push frame 29 of the hook assembly 28 contacts the limit portion 16 of the telescopic plate 17, the hook assembly 28 drives the telescopic plate 17 to retract through the limit portion 16, and the telescopic spring 8 stretches and returns to the initial position. The in-position sensor 4 sends a signal to stop the output shaft of the telescopic stepping motor 27 from rotating. At this time, the telescopic spring 8 is in the longest stretched state.

[0035] A telescopic limit block 11 is installed at the end of the telescopic guide rail 22 to limit the activity space of the telescopic plate 17 so that it slides within a safe range to increase the stability of the machine.

[0036] The mounting plate 21 is fixedly mounted with a rotating stepper motor 26, the fixed base plate 25 is fixedly mounted with a bearing 33 and a rotating gear 24, the mounting plate 21 is rotatably mounted on the fixed base plate 25 via the bearing 33, and the driving gear on the rotating stepper motor 26 and the rotating gear 24 are sleeved with a rotating chain 23. The power output shaft of the rotating stepper motor 26 drives the rotating chain 23 to rotate through the driving gear, so that the mounting plate 21 rotates around the central axis of the bearing 33.

[0037] The best embodiment of the present invention has been explained, and various changes or modifications made by ordinary technicians in this field will not depart from the scope of the present invention.
