Abstract
Description
Technical Field
[0001] The utility model relates to a three-dimensional warehouse, in particular to a graphite boat three-dimensional warehouse. Background Art
[0002] Graphite boats, mold carriers, are essential production aids in the production and processing of photovoltaic silicon wafers. They are both valuable and fragile. In recent years, the production and processing of photovoltaic silicon wafers has undergone three significant changes: first, their size has continued to expand, from 125mm×125mm to 210mm×210mm; second, the manufacturing process has become increasingly automated; and third, the production capacity of individual processing plants has increased from less than 1GW to 8-10GW. These changes have led to a corresponding increase in the size of graphite boats. Simultaneously, the rapid growth in factory production has also led to a rapid expansion in the number of graphite boats needed for storage, placing higher demands on their storage. Traditionally, the handling and storage of graphite boats in the photovoltaic wafer production process is manual, heavy, fragile, inefficient, labor-intensive, and difficult to recruit. This makes them unable to meet the high production paces required by smart factories and the digital management requirements for real-time information and data upload and sharing.
[0003] Currently, a utility model patented with patent publication number CN220578093U discloses a three-dimensional graphite boat storage system, comprising a storage device and a transport device arranged relative to each other, the storage device being used to accommodate graphite boats, and the transport device being used to retrieve and place graphite boats; the transport device comprising a first drive device and a second drive device, the first drive device and the second drive device being respectively connected to a carrying device, the first drive device driving the carrying device for relative movement in a first direction, the second drive device driving the carrying device for relative movement in a second direction, and the carrying device driving the graphite boat for relative movement in a third direction, wherein the orthographic projection of the carrying device on the storage device is located within the storage device along the third direction. The utility model realizes the orderly storage and retrieval of graphite boats by cooperating between the storage device and the transport device, making storage and / or retrieval of graphite boats more convenient, reducing the burden on staff through automated processing, reducing the space occupied by the graphite boats, and avoiding the problem of damage to the graphite boats caused by collisions.
[0004] From the above disclosed technical content, it can be seen that, as a prior art, the utility model with announcement number CN220578093U is a three-dimensional warehouse specially developed for graphite boats, which can effectively improve the storage capacity. However, since the connecting parts of its own storage device are horizontal and vertical frame structures, it is not stable enough, and the graphite boat storage position can only store one graphite boat, resulting in insufficient storage capacity. In addition, the second A drive device and the second B drive device of the patent can only ensure synchronous drive, and the sensing of its own moving position depends entirely on motor control, which will accumulate errors in long-term use, which requires frequent maintenance by staff to ensure the safe storage of the graphite boat. At the same time, there are inevitably some errors in the operation of the equipment during the storage and retrieval process of the graphite boat, which will cause the graphite boat to be skewed to a certain extent and need to be manually straightened, which is still not convenient enough in actual use. Summary of the Invention
[0005] In response to the problems existing in the above-mentioned prior art, the utility model provides a three-dimensional graphite boat warehouse, which can intelligently and efficiently perform automatic storage of graphite boats, effectively eliminate errors during storage of graphite boats, and ensure long-term stable operation of the equipment.
[0006] In order to achieve the above-mentioned purpose, the utility model provides a graphite boat stereoscopic warehouse, including a cross beam, a cross beam, a stereoscopic warehouse storage unit, an external frame of the storage unit, a double-position partition of the stereoscopic warehouse, a partition mounting beam, a ceiling rail, a stacker, a lifting mechanism, an encoder bracket, a follower wheel, a double-deep fork, a stacker frame, a ceiling rail guide wheel, a ground rail drive mechanism, a ground rail, a graphite boat automatic guide and positioning conveyor, a graphite boat and a reinforcing beam. The stereoscopic warehouse storage unit also includes an external frame of the storage unit, a double-position partition of the stereoscopic warehouse and a partition mounting beam. The external frame of the storage unit is sequentially installed with multiple double-position partitions of the stereoscopic warehouse from top to bottom through the partition mounting beam. Multiple stereoscopic warehouse storage units are arranged in parallel to form a stereoscopic warehouse unit. Cross beams are arranged at equal intervals between two oppositely installed stereoscopic warehouse units, and the cross beams are fixed by cross beams. The ceiling rail and the ground rail are respectively installed between the two oppositely installed stereoscopic warehouse units. The stacker moves back and forth between the ceiling rail and the ground rail. The graphite boat automatic guide and positioning conveyor is installed at the bottom of the stereoscopic warehouse storage unit.
[0007] In addition, the graphite boat stereoscopic warehouse proposed in the above embodiment of the present invention may also have the following additional technical features:
[0008] As a further improvement scheme of the present invention, the stacker includes a lifting mechanism, an encoder bracket, a follower wheel, a double-deep fork, a stacker frame and a ceiling rail guide wheel. The stacker frame moves back and forth on the ceiling rail and the floor rail through the ceiling rail guide wheel and the floor rail drive mechanism respectively. A liftable lifting mechanism is installed in the middle of the stacker frame, and a double-deep fork is installed on the lifting mechanism. An encoder is installed at the lower part of the stacker frame through the encoder bracket. The encoder's rotating shaft is connected to the follower wheel, and the follower wheel is attached to the floor rail.

[0010] As a further improvement of the present invention, the three-dimensional library storage unit and the ground rail are installed on the ground through ground nails.
[0011] As a further improvement of the present invention, the double-position partition of the stereoscopic warehouse is equipped with a photoelectric sensing device and a limit block, as well as an auxiliary touch wheel, a sensing plate substrate, a sensing plate spring shaft and a sensing plate photoelectric trigger plate for triggering the photoelectric sensing device.
[0012] As a further improvement of the present invention, the graphite boat automatic guiding and positioning conveyor includes two parallel conveyor belts and a belt driving device for driving the conveyor belts. Guide strips and guide plates are installed on the outer sides of the conveyor belts through brackets.
[0013] Through the above scheme, the utility model has at least the following advantages: compared with the conventional graphite boat storage method, the overall stability is improved by equipping the three-dimensional warehouse storage unit with cross beams and cross beams, so that the three-dimensional warehouse maintains extremely high stability during access. At the same time, the encoder on the encoder bracket is driven by the follower wheel of the stacker to measure the walking distance of the stacker, so that the lifting mechanism and the double-deep fork can be accurately aligned with the three-dimensional warehouse storage unit or the graphite boat automatic guide and positioning conveyor where the graphite boat needs to be stored and accessed. Finally, the graphite boat is automatically straightened by the automatic guide and positioning conveyor of the graphite boat, so that the graphite boat can enter the three-dimensional warehouse in a standard posture. By controlling variables and reducing errors through multiple links, the graphite boat can be automatically stored intelligently and efficiently, and errors during graphite boat storage can be effectively eliminated to ensure long-term stable operation of the equipment.

DETAILED DESCRIPTION
[0019] The graphite boat stereoscopic warehouse of the present invention will be described below with reference to the accompanying drawings.
[0020] In Example 1 of the present application, Figures 1 to 3 As shown, the graphite boat stereoscopic warehouse (hereinafter referred to as "the present invention") includes a cross beam 1, a cross beam 2, a stereoscopic warehouse storage unit 3, a ceiling rail 4, a stacker 5, a ground rail 6, a graphite boat automatic guide and positioning conveyor 7, a graphite boat 8 and a reinforcing beam 9. The stereoscopic warehouse storage unit 3 also includes a storage unit external frame 3-1, a stereoscopic warehouse double-position partition 3-2 and a partition mounting beam 3-3. The storage unit external frame 3-1 is sequentially installed with multiple stereoscopic warehouse double-position partitions 3-2 from top to bottom through the partition mounting beam 3-3. Multiple stereoscopic warehouse storage units 3 are arranged in parallel to form a stereoscopic warehouse unit. Cross beams 2 are arranged at equal intervals between two oppositely installed stereoscopic warehouse units, and the cross beams 2 are fixed by a cross beam 1. A ceiling rail 4 and a ground rail 6 are respectively installed between the two oppositely installed stereoscopic warehouse units. The stacker 5 moves back and forth between the ceiling rail 4 and the ground rail 6. A graphite boat automatic guide and positioning conveyor 7 is installed at the bottom of the stereoscopic warehouse storage unit 3.
[0021] The utility model with the utility model announcement number CN220578093U discloses a three-dimensional warehouse for graphite boats (hereinafter referred to as "the patent"). Although the patent, as a three-dimensional warehouse specially developed for graphite boats, can effectively improve the storage capacity, the connecting parts of its own storage device are horizontal and vertical frame structures, which are not stable enough, and the graphite boat storage position can only store one graphite boat, resulting in insufficient storage capacity. In addition, the second A drive device and the second B drive device of the patent can only ensure synchronous drive, and the sensing of its own moving position depends entirely on motor control, which will accumulate errors during long-term use, requiring staff to perform frequent maintenance to ensure the safe storage of the graphite boat. At the same time, there are inevitably some errors in the operation of the equipment during the storage and retrieval process of the graphite boat, which will cause a certain degree of deformation of the graphite boat. The degree of skewness requires manual straightening, which is still not convenient in actual use. The present invention uses a three-dimensional warehouse storage unit 3 equipped with a cross beam 1 and a cross beam 2 to improve the overall stability, so that the three-dimensional warehouse maintains extremely high stability during access. At the same time, the follower wheel 5-3 of the stacker 5 drives the encoder on the encoder bracket 5-2 to measure the travel distance of the stacker 5, so that the lifting mechanism 5-1 and the double-deep fork 5-4 can be accurately aligned with the three-dimensional warehouse storage unit 3 or the graphite boat automatic guide and positioning conveyor 7 where the graphite boat needs to be stored and accessed. Finally, the graphite boat is automatically straightened with the help of the graphite boat automatic guide and positioning conveyor 7, so that the graphite boat 8 can enter the three-dimensional warehouse in a standard posture, effectively improving the working accuracy of the three-dimensional warehouse, increasing the probability of reducing manual intervention, and improving the intelligence level of the equipment.
[0022] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 4 As shown, the stacker 5 includes a lifting mechanism 5-1, an encoder bracket 5-2, a follower wheel 5-3, a double-deep fork 5-4, a stacker frame 5-5, and overhead rail guide wheels 5-6. The stacker frame 5-5 moves back and forth on the overhead rail 4 and floor rail 6 via the overhead rail guide wheels 5-6 and the floor rail drive mechanism 5-7, respectively. A lift mechanism 5-1 is mounted in the middle of the stacker frame 5-5, on which the double-deep fork 5-4 is mounted. An encoder is mounted at the bottom of the stacker frame 5-5 via the encoder bracket 5-2. The encoder's rotating shaft is connected to the follower wheel 5-3, which is attached to the floor rail 6. The double-deep fork 5-4 can support the protrusions at both ends of the graphite boat 8 to transport the graphite boat 8.
[0023] In order to further optimize the working efficiency of the present application and further enhance the structural strength, the storage unit external frame 3-1 is equipped with a reinforcing beam 9. In order to make the equipment more stable, the three-dimensional warehouse storage unit 3 and the ground rail 6 are installed on the ground through ground nails. The three-dimensional warehouse double-position partition 3-2 is equipped with a photoelectric sensing device and a limit block, as well as an auxiliary contact wheel, a sensing plate substrate, a sensing plate spring shaft and a sensing plate photoelectric trigger plate for triggering the photoelectric sensing device. With the help of the photoelectric sensing device and the auxiliary contact wheel, the sensing plate substrate, the sensing plate spring shaft and the sensing plate photoelectric trigger plate for triggering the photoelectric sensing device, when the graphite boat 8 is lowered, it will press the auxiliary contact wheel, and the auxiliary contact wheel drives the sensing plate substrate to rotate with the sensing plate spring shaft as the center of the circle. The rotating sensing plate spring shaft drives the sensing plate photoelectric trigger plate to enter the corresponding through slot of the photoelectric sensing device to trigger the photoelectric sensor. The background can then determine that the position has been occupied by the graphite boat 8. When the graphite boat 8 leaves, the sensor plate spring shaft drives the sensor plate base plate and its auxiliary contact wheel and sensor plate photoelectric trigger plate to reset. The sensor plate base plate limit screw controls the position of the sensor plate base plate, placing the auxiliary contact wheel in the standby position. At this time, the backend can determine that the position is vacant. The graphite boat automatic alignment and positioning conveyor 7 includes two parallel conveyor belts and a belt drive device to drive the conveyor belts. Guide strips and guide plates are installed on the outer sides of the conveyor belts through brackets. When the material trolley places two graphite boats 8, they are first initially guided by the guide plates so that they enter the working range of the guide strips. Then the graphite boats 8 are lowered. The guide strips can provide further guidance for the graphite boats 8. At this time, the first graphite boat 8 has been aligned. The material trolley then lowers the second graphite boat 8. The graphite boat spacing control block cooperates with the conveyor belt to rotate synchronously in the opposite direction and is blocked by the rear limit block. At this time, the second graphite boat 8 is also aligned.
[0024] When in use, install the graphite boat stereoscopic warehouse and connect it with corresponding lines.
[0025] When the utility model is in use, the specific operations are as follows:
[0026] During operation, the material cart transports two graphite boats 8 to the automatic graphite boat alignment and positioning conveyor 7. After being aligned by the automatic graphite boat alignment and positioning conveyor 7, the double-deep forks 5-4 of the stacker 5 pick up the protrusions at both ends of the graphite boat 8 and lift the graphite boat 8. As the stacker 5 moves along the overhead rail 4 and floor rail 6, the follower wheel 5-3 drives the encoder on the encoder bracket 5-2, allowing the backend to accurately understand the stacker 5's travel distance, allowing the stacker 5's double-deep forks 5-4 to align with the corresponding double-position partition 3-2 of the three-dimensional warehouse. The double-deep forks 5-4 then transport the two graphite boats 8 to the double-position partition 3-2 of the three-dimensional warehouse, where they are stored. When removing the graphite boats, the destacker 5 transports the graphite boats 8 to the automatic graphite boat alignment and positioning conveyor 7 for easy access by the material cart.
[0027] In summary, the graphite boat three-dimensional warehouse of the embodiment of the present invention improves the overall stability by equipping the three-dimensional warehouse storage unit 3 with the cross beam 1 and the cross beam 2, so that the three-dimensional warehouse maintains extremely high stability during access. At the same time, the encoder on the encoder bracket 5-2 is driven by the follower wheel 5-3 of the stacker 5 to measure the travel distance of the stacker 5, so that the lifting mechanism 5-1 and the double-deep fork 5-4 can be accurately aligned with the three-dimensional warehouse storage unit 3 or the graphite boat automatic guiding and positioning conveyor 7 where the graphite boat needs to be stored and accessed. Finally, the graphite boat is automatically straightened with the help of the graphite boat automatic guiding and positioning conveyor 7, so that the graphite boat can enter the three-dimensional warehouse in a standard posture. By controlling variables and reducing errors through multiple links, the graphite boat can be automatically stored intelligently and efficiently, and errors during graphite boat storage can be effectively eliminated, ensuring long-term stable operation of the equipment.
