[0002] The production process of solar cells includes the PECVD process. In the existing PECVD process, the lifting and transfer of silicon wafer baskets is carried out by an integrated basket lifting mechanism. The process of transferring silicon wafer baskets using the existing basket lifting mechanism includes several steps: the basket frame lowers the empty basket, the empty basket is transferred out of the frame, the basket frame rises, and the loaded basket enters the frame. However, the existing basket lifting mechanism can only perform one step at a time, resulting in low basket transfer efficiency, discontinuous operation, and long equipment waiting time throughout the process. In addition, it increases the time that silicon wafers are exposed to air, increasing the probability of defective wafers.

[0003] Therefore, it is essential to provide a flower basket conveying device, flower basket conveying equipment, and battery production system that can improve the conveying efficiency, improve the conveying rhythm, and increase production capacity of flower baskets. Utility Model Content

When the first conveying tracks are close to each other, they receive flower baskets with filling and convey the flower baskets with filling. When the first conveying tracks are far apart, they avoid empty flower baskets descending.

[0030] Example:

[0031] Firstly, this application provides a flower basket conveying device, see [link to relevant documentation]. Figures 1 to 5 As shown, it includes a frame 1, a first flower basket conveying mechanism 2 disposed on the upper part of the frame 1, and a second flower basket conveying mechanism 3 disposed below the first flower basket conveying mechanism 2. The second flower basket conveying mechanism 3 is slidably connected to the frame 1 and moves up and down along a first direction z. The first flower basket conveying mechanism 2 includes a telescopic track 21 disposed opposite to each other along a second direction x. The telescopic track 21 includes a telescopic drive member 211 and a first conveying track 212 that moves along the second direction x under the drive of the telescopic drive member 211. When the first conveying tracks 212 are close to each other, they receive flower baskets with filling and convey the flower baskets with filling. When the first conveying tracks 212 are far apart, they avoid empty flower baskets descending. The second flower basket conveying mechanism 3 is used to receive empty flower baskets and then lift and convey the empty flower baskets downward.

[0032] The silicon wafer transport device described in this application includes a first basket transport mechanism 2 and a second basket transport mechanism 3 arranged vertically along a first direction z. The first basket transport mechanism 2 includes a telescopic track 21 that can be arranged relative to each other along a second direction x. The first transport track 212 moves relative to each other along the first direction z under the drive of the telescopic drive member 211. When a loaded flower basket is being fed, the first transmission track 212 moves closer to each other along the second direction x under the drive of the telescopic drive member 211, so that the first transmission track 212 receives and transports the loaded flower basket; when an empty flower basket needs to be discharged, the first transmission track 212 moves further apart along the second direction x under the drive of the telescopic drive member 211 to avoid the movement of the empty flower basket, and the second flower basket transmission mechanism 3 rises to lift the empty flower basket, which is then transported downwards by the second flower basket transmission mechanism 3; after the empty flower basket has completely passed through the telescopic track 21, the telescopic drive member 211 drives the first transmission track 212 to move closer to each other in preparation for the next transport of the loaded flower basket, thereby realizing the cyclical operation of feeding and discharging loaded and empty flower baskets, avoiding excessive waiting time for loaded flower baskets. The basket conveying device described in this application, through the cooperation between the first basket conveying mechanism 2 and the second basket conveying mechanism 3, uses the first basket conveying mechanism 2 to convey baskets with material, and the second basket conveying mechanism 3 to convey empty baskets by lifting and lowering. After the empty baskets are moved out of the area corresponding to the first basket conveying mechanism 2, the first basket conveying mechanism 2 can continue to convey baskets with material, reducing equipment waiting time, reducing time loss in basket conveying, and improving basket conveying efficiency and smoothness; it also reduces the waiting time for conveying baskets with material, reduces the time silicon wafers are exposed to air, and reduces the defect rate of silicon wafers; in addition, the overall structure of the basket conveying device is simple and easy to implement.

[0033] See Figures 1 to 3 As shown, the first flower basket transmission mechanism 2 further includes a support frame 22 connected to the frame 1, and the telescopic track 21 is disposed on the support frame 22; the telescopic drive member 211 is disposed inside the support frame 22 along the second direction x, and the first transmission track 212 extends along the third direction y; the first transmission track 212 includes a first transmission pulley 2121 disposed along the third direction y, a first transmission belt 2122 wound around the first transmission pulley 2121, and a rotation drive assembly 213 connected to any one of the first transmission pulleys 2121; the rotation drive assembly 213 is used to drive any one of the first transmission pulleys 2121 to rotate; the first transmission pulley 2121 is connected to the support frame 22 through a telescopic rod 2123.

[0034] The rotary drive assembly 213 includes a rotary drive member 2131 and a first drive wheel 2132 driven by the rotary drive member 2131; a telescopic rod 2123 connected to the first transmission pulley 2121 driven by the rotary drive assembly 213 passes through the support frame 22, and the end of the telescopic rod 2123 extending out of the support frame 22 is provided with a second transmission pulley 2133, which is tractively connected to the first drive wheel 2132.

[0035] The rotary drive component 2131 is mounted on the support frame 22, with its rotating end located on the outer side of the support frame 22. Optionally, in some embodiments, the first drive wheel 2132 is connected to the second transmission pulley 2133 via a synchronous belt. In use, the rotary drive component 2131 drives the first drive wheel 2132 to rotate, which in turn drives the second transmission pulley 2133 connected to it to rotate, thereby rotating the telescopic rod 2123. This, in turn, causes the first transmission pulley 2121 connected to the other end of the telescopic rod 2123 to rotate, which in turn drives the first transmission belt 2122 to rotate, thus achieving the transfer of the loaded flower basket. The support frame 22 has a connecting hole through which the telescopic rod 2123 passes, and a bearing connected to the telescopic rod 2123 is provided at the connecting hole.

[0036] Optionally, the telescopic drive component 211 may be a telescopic cylinder, and the first transmission track 212 is connected to the telescopic end of the telescopic drive component 211. Optionally, in some embodiments, the telescopic track 21 further includes a connecting plate disposed along a second direction x, the connecting plate being disposed at the telescopic end of the telescopic drive component 211, the telescopic rod 2123 being disposed through the connecting plate from the support frame 22, and the first transmission pulley 2121 being disposed on the inner side of the connecting plate.

[0037] Alternatively, in the two retractable runways 21 arranged opposite each other, at least one of the first transmission track 212 is provided with the rotation drive assembly 213.

[0038] Optionally, in some embodiments, either of the two opposing first transmission tracks 212 includes the rotary drive component 213. In use, the rotary drive component 213 drives the first transmission track 212 to move, causing the flower basket with material on the telescopic track 21 to move along the third direction y. The first transmission track 212 without the rotary drive component 213 moves synchronously with the first transmission track 212 with the rotary drive component 213 through the force between the track and the flower basket, thereby enabling both first transmission tracks 212 to jointly transport the flower basket. This structure only requires one rotary drive component 213 to achieve the transport of the flower basket, ensuring the transport of the flower basket while saving on the manufacturing cost of the flower basket transport device. In other embodiments, both of the two opposing telescopic tracks 21 include the rotary drive assembly 213. That is, the two opposing first transmission tracks 212 operate synchronously under the drive of the two rotary drive assemblies 213 to transport the loaded flower baskets. This configuration enhances the stable transmission power of the loaded flower baskets, ensuring stable and rapid transport. It is understood that when both opposing first transmission tracks 212 include the rotary drive assembly 213, the telescopic rods 2123, which are connected to the rotary drive assembly 213, pass through the support frame 22.

[0039] See Figure 2 and Figure 3 As shown, the first flower basket transmission mechanism 2 also includes a flower basket baffle 23 disposed between the outer side of the first transmission track 212 and the inner side of the support frame 22, and the flower basket baffle 23 is generally U-shaped.

[0040] In use, the basket baffle 23 facilitates the entry of the basket into the frame 1 while limiting its position, improving the stability of basket transport and preventing damage to the silicon wafers from basket shaking. It also guides the empty basket as it moves in the first reverse direction. Specifically, the basket baffle 23 includes a first baffle 231 parallel to the outer side of the first transmission belt 2122 along a third direction y, and a second baffle 232 perpendicular to the first baffle 231 along a second direction x. The first baffle 231 has holes through which the telescopic rod 2123 and the telescopic drive member 211 pass. The U-shaped structure formed by the first baffle 231 and the second baffle 232 allows the basket to smoothly enter the basket transport device from the notch opposite the second baffle 232 and be contained within it.

[0041] Furthermore, in some other embodiments, the top of the support frame 22 is also provided with a third baffle, which is disposed on the same side as the second baffle 232.

[0042] See Figure 1 and Figure 4 As shown, the first flower basket conveying mechanism 2 is slidably connected to the inner side of the frame 1 via the support frame 22; the inner side of the frame 1 is provided with a guide groove 11 arranged along the first direction z, and the support frame 22 is provided with a first protrusion 221 slidably connected to the guide groove 11. The support frame 22 is slidably connected to the inner side of the frame 1, making the position of the first flower basket conveying mechanism 2 adjustable, which facilitates the setting of the first flower basket conveying mechanism 2, the docking of the first flower basket conveying mechanism 2 with the material flower basket, and the adjustment of the corresponding position between the first flower basket conveying mechanism 2 and the second flower basket conveying mechanism 3.

[0043] See Figure 4 and Figure 5 As shown, the second flower basket transmission mechanism 3 includes a lifting platform 31 slidably connected to the frame 1 and a second transmission track 32 disposed on the upper surface of the lifting platform 31. The second transmission track 32 is arranged parallel to the third direction y. The second transmission track 32 includes a second transmission belt 321 disposed along the third direction y. The second transmission belt 321 is disposed in the projection area along the first direction z when the two first transmission tracks 212 are at their farthest relative distance, so that the second transmission belt 321 can be embedded between the first transmission tracks 212 to lift the empty flower basket.

[0044] The second flower basket conveying mechanism 3, through a sliding connection with the frame 1, drives the empty flower baskets supported thereon to move, thereby realizing the discharge operation of the empty flower baskets. In use, the lifting platform 31 moves upward along the first direction z until the second conveying track 32 is embedded in the area between the first conveying tracks 212, allowing the second conveying track 32 to support the bottom of the empty flower basket. Then, the lifting platform 31 moves downward along the first direction z, driving the empty flower baskets supported on the second flower basket conveying mechanism 3 downward. After the baskets are in position, the second transmission belt 321 transports the empty flower baskets out of the frame 1, completing the discharge of the empty flower baskets. It is understood that the second flower basket conveying mechanism 3 also includes a second rotary drive assembly 213 for driving the second transmission belt 321 to rotate.

[0045] The lifting platform 31 is provided with a second protrusion 311 that is slidably connected to the guide groove 11. It is understood that the flower basket conveying device further includes a lifting drive module for driving the first flower basket conveying mechanism 2 and the second flower basket conveying mechanism 3 to move up and down along the first direction z, respectively; the lifting drive module is respectively connected to the first protrusion 221 and the second protrusion 311 to drive the first flower basket conveying mechanism 2 and the second flower basket conveying mechanism 3 to move up and down along the guide groove 11 in the first direction z. It is understood that in this embodiment, the first conveying track 212 and the second conveying track 32 are belt conveying modules; optionally, in other embodiments, the first conveying track 212 and the second conveying track 32 may also be linear conveying modules.

[0046] It is understood that the basket conveying device described in this application is not only suitable for lifting and conveying silicon wafer baskets in the PECVD process of HJT heterojunction cells, but also for lifting and conveying sheet baskets in the chip manufacturing, PCB board industry or LED industry.

[0047] Secondly, this application provides a basket conveying device, which includes the basket conveying apparatus as described above. The basket conveying device includes at least one basket conveying apparatus; in some embodiments, when the number of basket conveying apparatuses is greater than one, multiple silicon wafer basket conveyors can be arranged sequentially and connected to each other via the rack 1. The basket conveying apparatus can efficiently convey baskets, reducing defective products caused by excessive equipment waiting time, thereby improving the overall conveying efficiency of the basket conveying device and the product yield.

[0048] Thirdly, this application provides a solar cell production system, which includes the basket conveying device described above. By employing a basket conveying device with high conveying efficiency, the basket conveying device achieves better conveying efficiency and a higher product yield, thereby improving the overall basket conveying efficiency of the solar cell production system and the yield of the produced products.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above embodiments merely illustrate preferred implementations of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application.
