[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figure 1-8 This utility model provides a technical solution: an intelligent temporary storage rack for AGV carts, including: a base frame 10, front and rear flapping assemblies 30, left and right flapping assemblies 40, and a lifting assembly 50; the top of the base frame 10 is provided with a top frame 20, and the two sides inside the base frame 10 are provided with inner frames 11, and the base frame 10 is used to store AGV carts; two sets of front and rear flapping assemblies 30 are provided, and the two sets of front and rear flapping assemblies 30 are respectively provided on the inner frames 11 on both sides inside the base frame 10, and each set of front and rear flapping assemblies 30 has two, and the left and right flapping assemblies 40 are provided between the two front and rear flapping assemblies 30 in each set, and the front and rear flapping assemblies 30 and the left and right flapping assemblies 40 are used to position and clamp the materials on the AGV cart; the lifting assembly 50 is provided at the bottom inside the inner frame 11, and the lifting assembly 50 is used to lift the materials on the AGV cart.

[0019] Specifically, after the AGV trolley carrying semiconductor materials is moved to the inside of the base frame 10, the position of the semiconductor materials is adjusted in the front-to-back direction by two sets of front and rear flap assemblies 30, and then the position of the semiconductor materials is adjusted in the left and right direction by two left and right flap assemblies 40. The semiconductor materials on the AGV trolley are positioned by the cooperation of the front and rear flap assemblies 30 and the left and right flap assemblies 40. Then, the positioned semiconductor materials are lifted by the lifting assembly 50. Next, the lifted semiconductor materials are clamped by the cooperation of the front and rear flap assemblies 30 and the left and right flap assemblies 40, thereby realizing the storage of semiconductor materials. This can accurately position and clamp the semiconductor materials to be stored, and avoid shaking or displacement during the transfer process, which may cause the semiconductor materials to collide or slip.

[0020] The top frame 20 has a barcode reader support frame 21 on one side of its front. The barcode reader support frame 21 has a barcode reader at its end. The encoder is connected to the PLC (Programmable Logic Controller) via a data cable and to the touch screen 23 via Ethernet. The barcode reader scans the barcode / QR code of the semiconductor material to obtain product information and LOT number, and then uploads it to the PLC.

[0021] The top frame 20 has a support rod 22 on the other side of its front. A touch screen 23 is located on the top of the support rod 22. The touch screen 23 communicates bidirectionally with the PLC (Programmable Logic Controller). When the barcode scanner detects information about semiconductor materials, it indicates that there are semiconductor materials in the bottom frame 10. The barcode scanner then sends a signal to the PLC, which in turn sends a signal to the touch screen 23, displaying the presence of materials. When the barcode scanner cannot detect information about semiconductor materials, it indicates that there are no semiconductor materials in the bottom frame 10. The barcode scanner then sends a signal to the PLC, which in turn sends a signal to the touch screen 23, displaying the presence of no materials.

[0022] Furthermore, by scanning the barcode / QR code of semiconductor materials with a barcode scanner to obtain product information and LOT number, the batch information of semiconductor materials can be accurately traced, avoiding material confusion and batch mismatch issues.

[0023] The inner frame 11 has a support beam 13 on the upper side of its inner side. The support beam 13 has two symmetrical front and rear flap assemblies 30 and left and right flap assemblies 40 at the center of the support beam 13. After the AGV trolley carrying semiconductor materials is moved to the inner side of the bottom frame 10, the position of the semiconductor materials is adjusted in the front and rear direction by the two sets of front and rear flap assemblies 30, and then the position of the semiconductor materials is adjusted in the left and right direction by the two left and right flap assemblies 40. The semiconductor materials on the AGV trolley are positioned by the cooperation of the front and rear flap assemblies 30 and the left and right flap assemblies 40.

[0024] The front and rear push plate assembly 30 includes a Y-hydraulic push rod 31 installed on the lower surface of the support beam 13. The output end of the Y-hydraulic push rod 31 is provided with front and rear push plates 32. After the AGV trolley carrying semiconductor materials is moved to the inside of the bottom frame 10, the Y-hydraulic push rod 31 pushes the front and rear push plates 32 to move in the front and rear direction. The four front and rear push plates 32 are positioned at the four corners of the semiconductor materials, thereby adjusting the position of the semiconductor materials in the front and rear direction.

[0025] The left and right push plate assembly 40 includes an X hydraulic push rod 41 installed at the center of the lower surface of the support beam 13. The output end of the X hydraulic push rod 41 is provided with left and right push plates 42. After the AGV trolley carrying semiconductor materials is moved to the inside of the bottom frame 10, the left and right push plates 42 are pushed by the X hydraulic push rod 41 to move in the left and right directions. The two left and right push plates 42 are positioned on the left and right sides of the semiconductor materials, thereby adjusting the position of the semiconductor materials in the left and right directions.

[0026] The inner frame 11 has a U-shaped bottom frame beam 12 at its rear bottom, and the lifting assembly 50 is located at the center of the U-shaped bottom frame beam 12. The lifting assembly 50 includes a Z-axis hydraulic push rod 51 fixedly installed at the center of the U-shaped bottom frame beam 12. The output end of the Z-axis hydraulic push rod 51 is provided with a lifting platform 52 for lifting the height of the material on the AGV trolley. After the semiconductor material on the AGV trolley is positioned, the semiconductor material is then lifted by the lifting assembly 50. Specifically, the lifting method is to lift the lifting platform 52 by the Z-axis hydraulic push rod 51, thereby lifting the semiconductor material.

[0027] The U-shaped bottom frame beam 12 has supporting vertical beams 14 on both sides of the Z-direction hydraulic push rod 51. The top of the supporting vertical beams 14 has a supporting plate 15. The lifting platform 52 is located above the supporting plate 15, and the output end of the Z-direction hydraulic push rod 51 passes through the supporting plate 15 and is fixedly connected to the lower surface of the lifting platform 52. The inner side of the lifting platform 52 has two symmetrical L-shaped supporting platforms. The L-shaped supporting platforms have air floats 60, which are used to support the materials on the AGV. When the Z-direction hydraulic push rod 51 is started, its output end drives the lifting platform 52 to move upward along the supporting vertical beam 14. At this time, the air floats 60 set on the L-shaped supporting platforms inside the lifting platform 52 also rises. The air floats 60 contact the bottom of the semiconductor materials on the AGV, and the air float principle is used to keep the materials stable during the lifting process, reduce the material deviation caused by friction or vibration, and ensure the accuracy and stability of the lifting action.

[0028] The support plate 15 has guide rods 54 on both sides of its upper surface, and the lifting platform 52 has guide cylinders 53 at both ends that cooperate with the guide rods 54. The guide cylinders 53 are slidably sleeved on the guide rods 54. During the movement of the lifting platform 52, the guide cylinders 53 at both ends of the lifting platform 52 cooperate with the guide rods 54 on both sides of the upper surface of the support plate 15. The guide cylinders 53 are slidably sleeved on the guide rods 54. This structure ensures that the lifting platform 52 can only move in a straight line along the axis of the guide rods 54, effectively preventing the lifting platform 52 from tilting or shaking during the lifting process, and further ensuring the safety and positioning accuracy of the semiconductor material during the lifting process.

[0029] The bottom frame 10 has a limiting component 70 on its inner back side to restrict the depth of the AGV trolley. The limiting component 70 includes a damper 71 mounted on the inner surface of the bottom frame 10, a limiting plate 72 at the end of the damper 71, and a positioning post 73 threaded onto the rear side of the end of the limiting plate 72. A positioning beam 16 is located on the inner back side of the bottom frame 10 corresponding to the positioning post 73. The limiting component 70 on the inner back side of the bottom frame 10 functions to limit the AGV trolley's movement inwards from the bottom frame 10. The plate 72 first contacts the AGV trolley, and the damper 71 acts as a buffer to reduce the impact force of the AGV trolley and bring it to a smooth stop. The positioning post 73, which is threaded on the rear side of the end of the limiting plate 72, cooperates with the positioning beam 16, which is correspondingly set on the back of the bottom frame 10, to precisely limit the position of the AGV trolley in the depth direction. This ensures that the AGV trolley is parked in the same position each time, and provides a reliable guarantee for the precise positioning and clamping of semiconductor materials by the front and rear plate assemblies 30 and the left and right plate assemblies 40.

[0030] Working principle: During use, the AGV trolley rotates the semiconductor material into the bottom frame 10. When the AGV trolley moves inward into the bottom frame 10, the limiting plate 72 first contacts the AGV trolley, and the damper 71 acts as a buffer to reduce the impact force of the AGV trolley, allowing the trolley to stop smoothly. At the same time, the two sides of the bottom of the semiconductor material on the AGV trolley are located above the air cushion 60. Then, the Y hydraulic push rods 31 of the two sets of front and rear flap assembly 30 push the front and rear push plates 32 to position the semiconductor material at the four corners, adjusting its position in the front-rear direction. Next, the X hydraulic push rods 41 of the two left and right flap assembly 40 push the left and right push plates 42 to position the semiconductor material on the left and right sides, adjusting its position in the left and right direction. Through the cooperation of the front and rear flap assembly 30 and the left and right flap assembly 40, the semiconductor material on the AGV trolley is accurately positioned. Subsequently, the Z-axis hydraulic push rod 51 of the lifting assembly 50 is activated, driving the lifting platform 52 to move upward along the support beam 14. The air-floating pad 60, located on the L-shaped support platform inside the lifting platform 52, rises accordingly and contacts the bottom of the semiconductor material on the AGV trolley. Utilizing the air-floating principle, the material remains stable during the lifting process, thus lifting the positioned semiconductor material. After lifting, the front and rear flapping assemblies 30 and the left and right flapping assemblies 40 work together to clamp the lifted semiconductor material, thereby achieving stable storage of the semiconductor material. At the same time, the barcode / QR code reader at the end of the barcode reader support frame 21 on one side of the front of the top frame 20 scans the barcode / QR code of the semiconductor material to obtain product information and LOT number, and uploads it to the PLC (Programmable Logic Controller). The PLC transmits the signal via Ethernet to the touch screen 23 on the top of the support rod 22 on the other side of the front of the top frame 20 for display. The operator can intuitively understand the storage status of the semiconductor material in the bottom frame 10 through the touch screen 23.

[0031] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
