[0029] refer to Figure 1 and Figure 2 The present disclosure provides a conveying device, including a base 8, at least two active pulleys 7 are installed on the base 8, a driving shaft 9 is connected to each active pulley 7, a supporting beam 15 is located on both sides of the base 8, one end of each supporting beam 15 is connected to the base 8, and a free pulley 17 is arranged at the other end, a conveyor belt 1 is sleeved on the active pulley 7 and the free pulley 17, a driving component is connected to the driving shaft 9 to drive the driving shaft 9 to rotate, a photoelectric detection component is used to detect the entry and exit and / or in-place status of materials on the conveyor belt 1, the driving shaft drives each active pulley to rotate simultaneously, and the free pulley rotates simultaneously with the conveyor belt, so that the conveyor belt can provide a smooth and efficient transmission process, avoid the overturning of the material frame during the transmission process, reduce the damage of the silicon wafer, and improve the quality and qualified rate of the product.

[0030] The conveying device provided by the present disclosure can be used to transport various materials, such as packaging boxes in industrial production, solar photovoltaic silicon wafers, etc., and is particularly suitable for transporting material frames containing silicon wafers. The following uses a material frame containing silicon wafers as an example to illustrate the operation process of the conveying device.

[0031] When the conveying device is in use, the material frame is placed on the conveyor belt 1, and the photoelectric detection component senses that the material frame driving component starts to work, and the drive shaft 9 connected thereto drives each active pulley 7 to move, and at this time the free pulley 17 moves accordingly, and the conveyor belt 1 is relatively fixed to the active pulley 7 and the free pulley 17, so that the conveyor belt 1 transports the material frame placed thereon to a predetermined position, and the photoelectric detection component at the predetermined position detects the material frame and sends a stop movement instruction to the driving component, so that the conveyor belt 1 can provide a smooth and efficient transmission process, avoid overturning of materials during transmission, reduce damage to silicon wafers, and improve product quality and qualified rate. In the present disclosure, the driving component can use any power structure that can rotate the drive shaft 9, and in addition, the conveying devices can be connected to each other to extend the transportation distance to meet the needs of working conditions.

[0032] In some embodiments, the driving component includes a motor base 3 connected to the support beam 15, a motor 19 installed on the motor base 3, a driving wheel 4 connected to the motor 19, and a driven wheel 6 connected to the drive shaft 9. The driven wheel 6 and the driving wheel 4 are connected by a transmission belt 5. By using the transmission belt 5 to connect the driving wheel 4 and the driven wheel 6, there is no direct contact between the two, which is beneficial to the arrangement of the driving parts. The separate design of the motor base 3 and the support beam 15 makes the disassembly and assembly of the motor 19 more convenient. The transmission belt 5 can absorb part of the vibration, reduce noise, and improve the stability and comfort of the equipment during operation. When the load is too large, the transmission belt 5 can play a certain overload protection role. The transmission belt 5 allows a certain degree of position deviation. The driving wheel 4 and the driven wheel 6 do not need to be precisely aligned, which improves the flexibility of installation and is beneficial to the compact arrangement of the conveying device structure.

[0033] In some embodiments, a first bracket 12 is provided on the base 8 to connect the active pulley 7, and a second bracket 16 is installed on the support beam 15 to connect the free pulley 17. The use of the first bracket 12 and the second bracket 16 makes the assembly of the entire driving component more modular, which is convenient for the independent installation and disassembly of each component, thereby simplifying the overall assembly process and making the replacement of the active pulley 7 and the free pulley 17 easier. The bracket includes the first bracket 12 and the second bracket 16. The components connected to the bracket only need to be decoupled from their respective brackets for replacement or maintenance. By using the bracket for support, the additional mechanical load on the base 8 and the support beam 15 can be reduced, thereby extending the service life. To extend the service life of the conveying device, the bracket can provide an additional support point for the driving pulley 7 or the free pulley 17, which helps to improve the stability and rigidity of the entire system and reduce vibration and noise during operation. The design of the bracket usually allows position adjustment within a certain range, which is very useful for ensuring that the transmission belt 5 is correctly tensioned and maintains a proper operating state. This adjustability is very important for equipment that runs for a long time. Different applications may require pulleys of different sizes. The design of the bracket is flexibly adapted to pulleys of different sizes, thereby increasing the versatility and flexibility of the system. In addition, the use of the bracket can reduce the design complexity of the base 8 and the support beam 15, thereby reducing manufacturing costs.

[0034] In some embodiments, the photoelectric detection component includes a photoelectric detection switch 13 located on the first bracket 12 and / or the second bracket 16, and the photoelectric detection switch 13 is electrically connected to the motor 19. When the material frame containing silicon wafers is detected, the motor 19 is turned on, so that the conveying device can automatically identify the material frame containing silicon wafers, and start or shut down the motor 19 when the material frame is detected. The automatic conveying process improves the automation level of the production line. Automatic detection and start-up can reduce waiting time and improve production efficiency; when no material frame passes or the material frame reaches the specified position, the motor will not start, which also means that energy can be saved. By automatically detecting the material frame, the stability and reliability of the conveying device are improved.

[0035] In some embodiments, a blocking rod 18 is installed on the second bracket 16 and is arranged opposite to the base 8. The blocking rod 18 is welded to the second bracket 16 or connected by bolts. The blocking rod 18 is used to block the material frame to facilitate the staff to take the material frame containing silicon wafers. The blocking rod 18 can also ensure that the material frame stops at a predetermined position, which can improve the efficiency of the staff in taking the material frame.

[0036] In some embodiments, a plurality of supporting rollers 11 are installed on the base 8, and the supporting rollers 11 are connected to the base 8 through a supporting roller seat 10, and the supporting roller seat 10 and the base are welded, and the supporting roller seat 10 and the supporting roller 11 are connected through a rotating shaft and installed on the top or side of the supporting roller seat 10. The transmitted material is supported by the supporting rollers 11, which can reduce the direct contact between the material frame and the base 8, thereby reducing the friction and making the movement of the material frame smoother. The plurality of supporting rollers 11 evenly distribute the weight of the material frame, reduce the load on a single supporting point, and improve the stability of the material frame transportation process and the durability of the equipment. The supporting rollers 11 can adapt to material frames of different sizes and shapes, and increase the versatility and flexibility of transmission.

[0037] In some embodiments, the tops of the support roller 11 and the conveyor belt 1 are at the same horizontal position, ensuring a smooth transition of the material frame from the support roller 11 to the conveyor belt 1, reducing the bumps and vibrations of the material frame during the transfer process, and helping to protect the material frame and the items loaded therein, such as silicon wafers. The same horizontal height helps to maintain the stability of the material frame during movement and avoid imbalance caused by height differences. The smooth transition reduces the resistance of the material frame during transmission, helping to improve the efficiency of the entire production line.

[0038] In some embodiments, a guide bar 2 is installed on the outside of the conveyor belt 1. The guide bar 2 is connected to the support beam 15 by bolts or welding. By bolting, corresponding slots can be set to assist in the installation of the guide bar 2. The guide bar 2 ensures that the material frame containing silicon wafers moves along a predetermined trajectory, which helps to keep the movement direction of the material frame consistent and reduce the possibility of deviation from the trajectory. The guide bar 2 provides additional support and guidance for the material frame, which helps to maintain the stability and balance of the material frame during movement. By limiting the movement range of the material frame, the guide bar 2 can prevent the material frame from accidentally shifting or overturning during movement, reducing damage to the silicon wafer. In addition, a groove is set on the guide bar 2 to match the boss set on the material frame, which is beneficial for the material frame to move along a predetermined trajectory.

[0039] In some embodiments, a plurality of support frames 14 are installed between adjacent support beams 15, and the support frames 14 are spaced apart along the length direction of the support beams 15. The support frames 14 strengthen the connection between the support beams 15, and improve the rigidity and stability of the entire structure, especially when reinforcing longer support beams 15. By installing a plurality of support frames 14 between the support beams 15, the load is dispersed to more support points, and the pressure on a single support beam 15 is reduced. The support frames 14 reduce the bending deformation of the support beam 15 due to heavy load, especially in the case of a large span. By reasonably arranging the number and position of the support frames, it helps to extend the service life of the support beam 15, achieve a good support effect, and control material and manufacturing costs at the same time.

The driving component includes a motor base 3 connected to the supporting beam 15, a motor 19 installed on the motor base 3, a driving wheel 4 connected to the motor 19, and a driven wheel 6 connected to the driving shaft 9.

[0042] The process of material conveying by the conveying device provided in the above specific embodiment is as follows: the material is conveyed to the conveyor belt 1 and the supporting roller 11. After the photoelectric detection switch 13 on the first bracket 12 senses the material, the electrical signal is converted into an opening command and transmitted to the motor 19. The motor 19 starts working after receiving the command from the photoelectric detection switch 13. The driving wheel 4 connected to the motor 19 rotates the driven wheel 6 through the transmission belt 5, and the driving shaft 9 rotates accordingly. The driving shaft 9 is transmitted to each active pulley 7 so that the conveyor belt 1 and the free pulley 17 move accordingly, and the object placed on the conveyor belt 1 is conveyed to a predetermined position. After the photoelectric detection switch 13 on the second bracket 16 detects the material, the electrical signal is converted into a stop or pause command and transmitted to the motor 19, and the motor 19 stops working.

[0043] The above scheme has the following advantages: the material (taking a material frame filled with silicon wafers as an example) is transferred via the support wheel 11, placed on the conveyor belt 1 and transported to the predetermined workstation.
