Among them, the structural schematic diagram of the overhead storage device in the prior art can be found in Figure 1 The high-altitude storage device includes: a pallet A, a wafer box B placed on the pallet A, and a fixing profile C that fixes the pallet A to the ceiling.

[0003] As a temporary storage unit for devices such as wafer boxes, the application of high-altitude storage devices can greatly reduce the distance that the overhead crane moves to pick up the wafer box, effectively reduce the handling distance of the overhead crane, improve production efficiency and save clean space. However, traditional high-altitude storage devices have only one layer, and one storage space can only store one wafer box, which seriously underutilizes the high altitude of the clean room.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0030] According to an embodiment of the present invention, a high-altitude storage device is provided. Figures 2 to 13 , including: a support 1, a turntable assembly 2 and a turntable control system; the turntable assembly 2 is rotatably arranged on the support 1, and a plurality of storage baskets 21 are arranged on the turntable assembly 2, each storage basket 21 is used to place a wafer box; the turntable control system is used to read the current position information of the turntable assembly 2, and adjust the rotation angle of the turntable assembly 2 according to the control instruction of the overhead crane control system, so that the storage basket 21 in the turntable assembly 2 runs to the position specified by the overhead crane control system. Figure 1 As shown, the fixed profile C of the traditional high-altitude storage device is installed on the ceiling, the storage tray A has only one layer, and one storage position can only store one wafer box B, which seriously underutilizes the high-altitude of the clean room. Figure 2The high-altitude storage device of this embodiment utilizes vertical space to place multiple storage baskets 21, and can be flexibly rotated to a designated position through the turntable assembly 2, making full use of the high-altitude space. Compared with the horizontal layout storage method, this design can achieve larger capacity storage on a limited floor space, and is particularly suitable for high-density storage needs. The position information of the turntable assembly 2 is automatically read by the turntable control system, and the angle of the turntable assembly 2 can be accurately adjusted according to the instructions of the overhead crane control system, so that the designated storage basket 21 can be quickly moved to the desired position. This automated positioning method greatly improves operational efficiency and reduces the risks of manual positioning and misoperation. The turntable control system works in conjunction with the overhead crane control system to integrate the grabbing and placing operations into an integrated control process, which is convenient for realizing automated and intelligent control. The high-altitude storage device of this embodiment solves the technical problem of limited storage space in high-altitude storage devices in related technologies.

[0031] See also Figure 2 In the high-altitude storage device of this embodiment, the turntable assembly 2 includes a first turntable 22 and a second turntable 23 arranged opposite to each other, and the first turntable 22 and the second turntable 23 are supported by a plurality of parallel shafts 24; a storage basket 21 is suspended on each shaft 24. The first turntable 22 and the second turntable 23 are arranged opposite to each other and connected and supported by parallel shafts 24 to form a stable frame structure. This double turntable design can more evenly distribute the load and improve the stability of the overall structure. It is particularly suitable for storage applications in high-altitude environments and avoids the tilting and shaking that may be caused by a single turntable design.

[0032] See also Figure 2 In the high-altitude storage device of this embodiment, the turntable assembly 2 also includes a turntable shaft 26 equipped with a driving device 25, and the driving device 25 is connected to the turntable control system; the centers of the first turntable 22 and the second turntable 23 are both provided with a through hole 27, and the first turntable 22 and the second turntable 23 are sleeved on the turntable shaft 26 through the through hole 27, and the driving device 25 drives the turntable shaft 26 to rotate, thereby driving the first turntable 22 and the second turntable 23 to rotate. The driving device 25 directly acts on the turntable shaft 26, and drives the rotation of the two turntables through the turntable shaft 26, thereby reducing the intermediate transmission components, simplifying the transmission chain, and reducing energy loss. The driving device 25 is connected to the turntable control system, and can accurately control the rotation angle of the turntable shaft 26 according to the instructions, so as to realize the precise positioning of the first turntable 22 and the second turntable 23. This design enables the storage basket 21 to be quickly aligned to the target position.

[0033] See also Figure 2In the high-altitude storage device of this embodiment, the shaft rod 24 is rotatably arranged relative to the first turntable 22 and the second turntable 23, and a limiting groove 241 is arranged on the shaft rod 24; the high-altitude storage device also includes a limiting assembly 3, the limiting assembly 3 includes a through hole 33 for the shaft rod 24 to pass through, a limiting member 31, and a driving component 32 for prompting the limiting member 31 to move; when the driving component 32 is in a first state, the limiting member 31 leaves the limiting groove 241, so that the shaft rod 24 can rotate freely in the through hole 33 relative to the first turntable 22 and the second turntable 23, so that the storage basket 21 can maintain a horizontal state under the action of gravity; when the driving component 32 is in a second state, the limiting member 31 enters the limiting groove 241, fixes the shaft rod 24 to the through hole 33, so as to prevent the storage basket 21 from rotating. The high-altitude storage device of this embodiment adopts the structure of the limit groove 241 and the limit member 31. When the driving component 32 is in the first state, the limit member 31 is disengaged from the limit groove 241, and the shaft 24 can rotate freely in the through hole 33, so that the storage basket 21 maintains a horizontal state under the action of gravity. This design effectively prevents the storage basket 21 from tilting due to the rotation of the first turntable 22 and the second turntable 23, thereby ensuring the stability of the wafer box, which is suitable for high-altitude storage. By switching the state of the driving component 32, the limit member 31 can move inside and outside the limit groove 241, thereby realizing the rapid fixation or release of the shaft 24. When the driving component 32 is in the second state, the limit member 31 enters the limit groove 241, fixes the shaft 24, and locks the storage basket 21 relative to the first turntable 22 and the second turntable 23. The fixing and release of the shaft 24 are realized by controlling the movement of the limit member 31 by the driving component 32. The structure is simple, the manufacturing cost is low, and it is convenient for mass production and maintenance. The storage basket 21 rotates with the first turntable 22 and the second turntable 23, which can fully utilize the vertical space of the clean room. Compared with the traditional single-layer storage method, the number of storage baskets 21 is greatly increased, thereby meeting the growing storage demand.

[0034] See also Figure 2 and Figure 3 In the high-altitude storage device of this embodiment, there are multiple groups of limit assemblies 3, and both ends of the shaft 24 are connected with corresponding limit assemblies 3. Both ends of each shaft 24 are connected with limit assemblies 3, and the shaft 24 can be limited and supported at both ends when the first rotating disk 22 and the second rotating disk 23 rotate, thereby reducing the shaking of the shaft 24 and enhancing the stability of the storage basket.

[0035] See also Figure 4 , Figure 5 and Figure 7 The limiting grooves 241 are arranged at both ends of the shaft 24, and the shaft 24 with the limiting grooves 241 extends into the through hole 33 of the limiting assembly 3. The limiting assembly 3 is fixed on the first rotating disk 22 and the second rotating disk 23, and is a block structure (such as Figure 7241 ), and has a cavity for accommodating a stopper 31 and a driving component 32, both of which are located in the cavity. A sleeve is arranged in the cavity, and the sleeve is a hollow structure so as to form a through hole 33 for the shaft 24 to rotate. A circular hole is arranged on the wall of the sleeve, and the circular hole is arranged corresponding to the stopper groove 241, so that the through hole 33 is communicated with the cavity, so that the stopper 31 can shuttle between the through hole 33 and the cavity.

[0036] See also Figure 6 , Figure 7 and Figure 8 In the high-altitude storage device of this embodiment, the driving component 32 is a motor gear set 321 and is fixed on the first rotating disk 22 and the second rotating disk 23. The limiting member 31 is a push rod 311. The push rod 311 is provided with a tooth groove 3111 meshing with the gear of the motor gear set 321 and is arranged corresponding to the limiting groove 241. The motor gear set 321 drives the push rod 311 to be movably arranged; when the motor of the motor gear set 321 rotates forward, the push rod 311 moves in a direction away from the limiting groove 241; when the motor of the motor gear set 321 rotates reversely, the push rod 311 moves in a direction close to the limiting groove 241, so that the push rod 311 enters the limiting groove 241, thereby fixing the shaft rod 24 and preventing the shaft rod 24 from rotating in the through hole 33. When the motor gear set 321 rotates reversely, the push rod 311 moves and enters the limiting groove 241, thereby firmly fixing the shaft rod 24 and preventing the shaft rod 24 from rotating freely in the through hole 33. This design enhances the locking effect of the stopper 31, so that the storage basket 21 remains stable when the first turntable 22 and the second turntable 23 rotate. The push rod 311 is driven to move in a specific direction by the motor gear set 321, so that the push rod 311 can be precisely controlled. When the motor rotates forward or reverse, the push rod 311 moves away from or approaches the stopper slot 241, thereby flexibly controlling the locking or release of the shaft 24.

[0037] See also Figure 8 In the high-altitude storage device of this embodiment, a ball 3112 is provided at the end of the push rod 311. When the push rod 311 fixes the shaft 24, the ball 3112 is located in the limiting groove 241. When the push rod 311 enters the limiting groove 241 to fix the shaft 24, the ball 3112 at the end can be accurately embedded in the limiting groove 241. The ball structure provides a more stable contact surface, which is not easy to slide or fall out, ensuring the firmness of the shaft 24 in the limited state and improving the safety of the storage basket in the fixed state.

[0038] See also Figure 8In the high-altitude storage device of this embodiment, a guide rod 312 is provided on the side of the push rod 311 away from the tooth groove 3111. When the push rod 311 moves, the guide rod 312 is used to guide the moving direction of the push rod 311 to prevent the push rod 311 from deflecting during the movement. The guide rod 312 is provided on the side of the push rod 311 away from the tooth groove, and is used to guide the moving direction of the push rod 311 to prevent the push rod 311 from deflecting under the drive of the motor gear set 321, ensuring that the push rod 311 always maintains a linear motion during the movement, avoiding inaccurate limit caused by deviation, and improving the reliability of the limit operation.

[0039] See also Fig. 9 and Fig.10 In the high-altitude storage device of this embodiment, the limiting member 31 is a sleeve 313 and a plurality of limiting balls 314 that can move on the sleeve 313. The sleeve 313 is provided with a round hole 3131, and each limiting ball 314 can move through the round hole 3131. The sleeve 313 is fixed on the first turntable 22 and the second turntable 23, and the sleeve 313 is sleeved on the shaft rod 24. The sleeve 313 is arranged around the outer periphery of the through hole 33; the driving component 32 is an electromagnetic ring 322, and the electromagnetic ring 322 is fixed on the first turntable 22 and the second turntable 23, and the electromagnetic ring 322 is sleeved on the sleeve 313; when the electromagnetic ring 322 is in a power-on state, the electromagnetic ring 322 attracts each limiting ball 314 so that the limiting balls 314 are dispersed toward the outer periphery of the sleeve 313; when the electromagnetic ring 322 is in a power-off state, the limiting balls 314 located above the limiting groove 241 fall into the limiting groove 241. The electromagnetic ring 322 is used as a driving component to control the spreading and returning of the limiting ball 314 by powering on and off. When powered on, the electromagnetic ring 322 attracts the limiting ball 314 to spread to the outer periphery of the sleeve 313, so that the shaft 24 can rotate freely; when powered off, the limiting ball 314 falls into the limiting groove 241 under the action of gravity, realizing accurate fixation of the shaft 24. This control method ensures the stability and reliability of the limiting operation.

[0040] See also Figure 2 In the high-altitude storage device of this embodiment, the driving device 25 is a motor 251, which is fixed on the bracket 1. The motor 251 is located on the side of the bracket 1 away from the first turntable 22 and the second turntable 23. The output end of the motor 251 is connected to the turntable shaft 26 to drive the turntable shaft 26 to rotate. Each set of limit components 3 is located between the first turntable 22 and the second turntable 23. The motor 251 is set on the bracket 1 and located on one side of the two turntables, and will not occupy the space between the turntables. Each set of limit components 3 is located between the two turntables, so that the layout of the limit components 3 and the motor 251 is reasonable, ensuring the compact structure of the turntable assembly 2, while providing more available space for operation.

[0041] See also Fig.11The overhead crane system of this embodiment also includes a transmission frame 4 and a pick-and-place assembly 5. The transmission frame 4 is provided with a conveyor belt 41, and the pick-and-place assembly 5 is movable on the conveyor belt 41; when the turntable assembly 2 rotates to the specified position, the pick-and-place assembly 5 extends into the storage basket 21 to complete the grabbing or placing operation of the wafer box. The overhead crane system can be linked with the turntable assembly and the control system of the high-altitude storage device. When the storage basket 21 moves to the specified position, the pick-and-place assembly 5 can be precisely operated. This systematic integrated design ensures the accuracy of storing and accessing wafer boxes, improves the accuracy of wafer box positioning, and is suitable for application scenarios with high precision requirements.

[0042] See also Fig.12 The overhead travelling vehicle system of this embodiment further includes a side shift assembly 8, through which the pick-and-place assembly 5 is connected to the conveyor belt 41, and the side shift assembly 8 can move in a direction perpendicular to the running direction of the conveyor belt 41 to drive the pick-and-place assembly 5 to extend into the storage basket 21. The side shift assembly 8 enables the pick-and-place assembly 5 to perform precise lateral movement in a direction perpendicular to the conveyor belt 41, thereby realizing flexible positioning of the storage basket 21.

[0043] The control method of the high-altitude storage device of this embodiment includes: reading the current position information of the turntable assembly 2 and receiving the control command of the overhead crane control system; adjusting the rotation angle of the turntable assembly 2 according to the control command of the overhead crane control system, so that the storage basket 21 in the turntable assembly 2 runs to the position specified by the overhead crane control system. This method ensures that the storage basket 21 can be accurately aligned to the pick-up and placement position specified by the overhead crane, meeting the requirements of high-precision storage and pick-up.

[0044] In the control method of the high-altitude storage device of this embodiment, the turntable control system also includes a code reader 6 and a barcode 7. The code reader 6 is arranged on the bracket 1, and the barcode 7 is attached to the turntable assembly 2, so that the barcode 7 corresponds to the storage basket 21 on the turntable assembly 2. The target barcode is read by the code reader 6, and the turntable control system feeds back the read information to the overhead crane control system. The barcode information is read by the code reader 6 and fed back to the overhead crane control system. The turntable control system can monitor the position of the storage basket 21 in real time and transmit data, providing data support for intelligent scheduling. The overhead crane system can perform more reasonable scheduling and task allocation based on real-time feedback information.

[0045] The control method of the overhead crane system of this embodiment includes: receiving a wafer disc grabbing instruction from a user, the wafer disc grabbing instruction at least including the position information of the wafer box; converting the wafer disc grabbing or placing instruction into a control instruction and sending it to the turntable control system, so that the turntable control system adjusts the rotation angle of the turntable assembly 2 according to the control instruction. The grabbing and placing instructions of the wafer disc can be automatically converted into the control instructions of the turntable assembly, so that the turntable assembly can adjust the angle autonomously according to the instructions of the control system. The method realizes the linkage between the overhead crane system and the turntable control system through the control instructions, so that each system can work together to ensure that the storage basket can be quickly positioned to the target position, thereby improving the response speed and operation smoothness of the system.

[0046] In the control method of the overhead crane system of this embodiment, the turntable control system feeds back the information that the target storage basket has been adjusted and fixed to the overhead crane control system, and the overhead crane control system performs the operation of reaching into the target storage basket to complete the grabbing or placing action of the wafer box. After the positioning is completed, the turntable control system feeds back the information of "adjustment and fixing completed" to the overhead crane system, so that the overhead crane system has a clear confirmation step before taking and placing the wafer box. The feedback mechanism ensures that the storage basket has been correctly positioned and fixed before the pick-and-place operation is performed, avoiding grabbing failure or damage to the wafer box due to failure to be in place, thereby improving the safety of the entire system.

[0047] See also Figure 2 and Fig.13In the high-altitude storage device of this embodiment, 6 storage baskets 21 are set as an example, and they are numbered 1, 2, 3, 4, 5, and 6 in the turntable control system. Since the bar code 7 is a circular ring, it can be divided into 360°. If the positions of 60°, 120°, 180°, 240°, 300°, and 360° correspond to the positions of the storage baskets 21 numbered 1, 2, 3, 4, 5, and 6 respectively. If the position information of the high-altitude storage device is L001, when it is necessary to grab the wafer box in the storage basket 21 numbered 3, the position information of the wafer box is L001-3, and the position information is bound to the wafer box position information and stored in the overhead crane system. The overhead crane system issues an instruction to the overhead crane to go to L001-3 to grab the wafer box, and the overhead crane system synchronously conveys the instruction information to the turntable control system of the high-altitude storage device. The turntable control system executes the action of rotating the storage basket 21 numbered 3 to the overhead crane grabbing position according to the position information L001-3. The turntable control system controls the electromagnetic ring 322 on the shaft 24 to be energized. After the electromagnetic ring 322 is energized, it will generate magnetic force, which will attract the limit ball 314, so that the limit ball 314 will be separated from the limit groove 241 on the shaft 24, and the shaft 24 can rotate freely. The turntable control system controls the motor 251 and the barcode reader 6 to start working. The motor 251 drives the two turntables to rotate, and the barcode reader 6 reads and feeds back the position information of the turntable to the turntable control system in real time. When a specific barcode is read, such as the 180° barcode, it means that the No. 3 storage basket 21 has reached the crane grabbing position. The turntable control system feeds back the brake information to the motor 251, and the motor 251 brakes and stops rotating. At the same time, the turntable control system controls the electromagnetic ring 322 to be de-energized, so that the limit ball 314 falls into the limit groove 241 on the shaft 24, so that the shaft 24 cannot rotate, and the storage basket 21 is stably fixed. The turntable control system feeds back the information that the storage basket 21 position is ready to the crane system, indicating that the crane can normally pick up and place the wafer box at this time. The control system of the overhead crane synchronously feeds back the information that the pick-up and placement can be performed normally to the overhead crane. After the overhead crane reaches the destination, the side shift assembly 8 extends, and the pick-up and placement assembly 5 grabs the wafer box stored in the storage basket 21.
