Description

Technical Field

[0002] Perovskite solar cells are an emerging technology that uses organic semiconductor materials to generate electricity under the influence of light. Their high conversion efficiency, environmental friendliness, and stable power generation make them one of the mainstream trends in photovoltaic product development. The fabrication of perovskite solar cells involves multiple processes, thus requiring multiple process stages. For example, stages such as slot coating, vacuum drying, and annealing are necessary.

[0003] After completing one process, perovskite products need to be transferred to another for the next. In existing processes, robotic arms are used to move these products from one stage to the next. Large-scale perovskite battery production lines require multiple robotic arms for this purpose, and the high cost of these arms contributes to the overall high construction cost of the production line. Furthermore, perovskite products are typically based on lightweight and fragile glass substrates, with the perovskite layer fabricated on top. When using robotic arms to transfer perovskite products, alignment devices are required each time the product is transferred to ensure accurate gripping by the robotic arms and prevent damage from improper handling. However, the use of multiple alignment devices further complicates the structure of the perovskite battery production line and increases construction costs. Utility Model Content

[0033] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0034] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0035] like Figures 1 to 7 As shown, this utility model provides a perovskite wafer transfer device for transferring perovskite products. The perovskite product can be a substrate coated with perovskite slurry. The perovskite wafer transfer device includes a transfer chamber 1, a transfer assembly 2, and a drive assembly 3.

[0036] Reference Figures 1 to 3The transfer chamber 1 has an internal space 11 for the movement of perovskite products. This internal space 11 is a sealed space. Specifically, the transfer chamber 1 is formed by its four side walls 12, top wall 13, and floor. The connections between the side walls 12, top wall 13, and floor are sealed to create a sealed space. To facilitate the movement of the perovskite products, the side walls 12 of the transfer chamber 1 may have openings 121 and a first control valve 122 for sealing or opening the openings 121. When perovskite products need to be moved into the transfer chamber 1, the first control valve 122 opens the opening 121, allowing the perovskite products to move into the transfer chamber 1. Afterward, the first control valve 122 can seal the opening 121 to create a sealed space within the transfer chamber 1. Furthermore, to facilitate the removal of the perovskite product, an outlet 123 and a second control valve 124 for sealing or opening the outlet 123 can be provided on the other side wall 12 of the transfer chamber 1. When it is necessary to remove the perovskite product from the transfer chamber 1, the second control valve 124 opens the outlet 123, and the perovskite product is removed from the transfer chamber 1 through the outlet 123. Afterwards, the second control valve 124 seals the opening 121 to form a sealed space within the receiving space 11 of the transfer chamber 1. The wall with the opening 121 and the wall with the outlet 123 can be opposite side walls of the transfer chamber 1. The first control valve 122 and the second control valve 124 can be driven by a cylinder or other driving structure, respectively. The first control valve 122 and the second control valve 124 can be plate structures capable of sealing the opening 121 and the outlet 123.

[0037] To facilitate limiting the movement of the control valve, a first limiting component 14 can be provided on the transfer chamber 1. The first limiting component 14 can be located on the side wall 12 of the transfer chamber 1 where the opening 121 is located, and can be positioned on opposite sides of the first control valve 122 along its direction of movement. Specifically, the first control valve 122 can move vertically, and the first limiting component 14 can be positioned above and below the first control valve 122. The first limiting component 14 may include one or more limiting blocks. When the first control valve 122 moves downward to its maximum stroke, the first control valve 122 abuts against the limiting block of the lower first limiting component 14; when the first control valve 122 moves upward to its maximum stroke, the first control valve 122 abuts against the limiting block of the upper first limiting component 14. The movement of the first control valve 122 is limited by the first limiting component 14 located in the vertical direction of the first control valve 122.

[0038] Furthermore, the first limiting component 14 can also be disposed on the side wall 12 of the outlet 123 of the transfer chamber 1, and the first limiting component 14 is disposed on opposite sides of the second control valve 124 along the moving direction of the second control valve 124. Specifically, the second control valve 124 can move vertically, and the first limiting component 14 can be disposed above and below the second control valve 124. The first limiting component 14 may include one or more limiting blocks. When the second control valve 124 moves downward to its maximum stroke, the second control valve 124 abuts against the limiting block of the lower first limiting component 14; when the second control valve 124 moves upward to its maximum stroke, the second control valve 124 abuts against the limiting block of the upper first limiting component 14. The movement of the second control valve 124 is limited by the first limiting component 14 located in the vertical direction of the second control valve 124.

[0039] Reference Figures 4 to 6 The transfer assembly 2 is disposed within the receiving space 11 and is used to receive and support the perovskite product entering the receiving space 11 through the opening 121. The transfer assembly 2 can move the perovskite product from the opening 121 to the outlet 123 and remove the perovskite product from the outlet 123. The transfer assembly 2 may include a support bracket 21, a transfer roller 22, and a transfer shaft 23. The support bracket 21 may be fixed within the transfer chamber 1, and a pair of support brackets 21 may be provided, with the pair of support brackets 21 arranged opposite each other and forming a space between the pair of support brackets 21 for the movement of the perovskite product. The transfer roller 22 is fixedly connected to the transfer shaft 23 so that the transfer roller 22 and the transfer shaft 23 can rotate synchronously. The transfer shaft 23 is mounted on the support bracket 21, and the transfer roller 22 is mounted on the support bracket 21 through the transfer shaft 23; specifically, the transfer shaft 23 is disposed on opposite sides of the transfer roller 22, and the two transfer shafts 23 are correspondingly connected to the pair of support brackets 21 so that the transfer roller 22 is supported between the pair of support brackets 21.

[0040] The transfer roller 22 receives and supports the perovskite product, and the transfer shaft 23 is connected to the drive assembly 3 so that the drive assembly 3 can drive the transfer shaft 23 to rotate, thereby causing the transfer roller 22 to rotate. The transfer roller 22 transfers the perovskite product and can move the perovskite product from the opening 121 to the outlet 123. Multiple transfer rollers 22 can be provided, each transfer roller 22 is connected to the transfer shaft 23 and installed between a pair of support brackets 21 through the corresponding transfer shaft 23. The multiple transfer rollers 22 are arranged sequentially along the transfer path of the perovskite product so that the perovskite product can move along the transfer path under the drive of the multiple transfer rollers 22.

[0041] By setting multiple transfer rollers 22 within the accommodating space 11 to drive the perovskite product, the structure is simple and the cost is low. Compared to the robotic arm transfer method, the transfer rollers 22 do not require a pre-set alignment device to pre-position the perovskite product, which simplifies the structure of the perovskite battery production line and reduces the construction cost. The opening of the transfer chamber 1 is adjacent to the previous process section, and the outlet 123 of the transfer chamber 1 is adjacent to the previous process section. By setting the perovskite wafer transfer device of this application at corresponding positions in the perovskite battery production line, the perovskite battery production line can form open-loop and closed-loop structures, improving efficiency and space utilization.

[0042] Reference Figure 4 During the movement of the perovskite product on the transfer roller 22, the perovskite product may experience lateral displacement. To ensure the positional accuracy of the perovskite product during movement, a second limiting component 15 can be provided on the support bracket 21. Specifically, the second limiting component 15 includes a pair of limiting members 151, which are correspondingly disposed on a pair of support brackets 21 and are positioned opposite each other. The spacing between the pair of limiting members 151 is adapted to the width of the perovskite product; for example, the spacing between the pair of limiting members 151 is the same as or slightly larger than the width of the perovskite product. When the perovskite product moves on the transfer roller 22, the pair of limiting members 151 restricts the lateral movement of the perovskite product to ensure the positional accuracy of the perovskite product during movement.

[0043] Multiple second limiting components 15 can be provided, and these components are arranged sequentially and at intervals along the moving direction of the perovskite product. Each second limiting component 15 is used to restrict the lateral movement of the perovskite product. To reduce friction between the second limiting components 15 and the perovskite product, the limiting element 151 in the second limiting component 15 can be a limiting wheel. When the limiting wheel contacts the perovskite product, it can rotate to reduce the friction between the perovskite product and the limiting element 151.

[0044] Because there is a certain gap between the opening 121 and the transfer roller 22, when the perovskite product moves from the opening 121 towards the transfer roller 22, the front end of the perovskite product will be suspended for a period of time. When the front end of the perovskite product contacts the transfer roller 22, it is supported by the transfer roller 22 and thus the suspension state is lifted. However, when the front end of the perovskite product is suspended, there is no force point to support the front end of the perovskite product, which leads to the risk of the perovskite product tipping over. To solve this problem, the perovskite sheet transfer device can be equipped with a first support wheel 16. The first support wheel 16 can be set between the opening 121 and the transfer roller 22, and the first support wheel 16 is used to support the perovskite product.

[0045] As the perovskite product moves from the opening 121 toward the transfer roller 22, its front end first contacts and is supported by the first support wheel 16. This reduces the time the front end of the perovskite product is suspended in the air and provides a support point as it moves from the opening 121 toward the transfer roller 22, effectively preventing the perovskite product from tipping over. Furthermore, during the movement, the first support wheel 16 can rotate to reduce the friction between the first support wheel 16 and the perovskite product.

[0046] Furthermore, due to the gap between the transfer roller 22 and the outlet 123, the front end of the perovskite product may be suspended in the air for a period of time as it moves from the transfer roller 22 towards the outlet 123, potentially leading to tipping over. To address this issue, the perovskite sheet transfer device can be equipped with a second support wheel 16. The second support wheel 16 can be positioned between the transfer roller 22 and the outlet 123, and it supports the perovskite product. When the perovskite product moves from the transfer roller 22 towards the outlet 123, its front end first contacts and is supported by the second support wheel 16, reducing the suspension time and providing a support point as it moves from the transfer roller 22 towards the outlet 123, effectively preventing tipping over. Additionally, during the movement, the second support wheel 16 can rotate to reduce friction between it and the perovskite product.

[0047] Reference Figure 6 The drive assembly 3 includes a drive element 31, a flange assembly 33, and a magnetofluid 32. The flange assembly 33 is fixed to the support bracket 21, and an installation gap is formed between the flange assembly 33 and the transmission shaft 23. The magnetofluid 32 is disposed within this installation gap to achieve a sealed connection between the drive assembly 3 and the transmission shaft 23. The flange assembly 33 may include a flange 331 and a flange cover 332. The flange 331 is fixedly connected to the support bracket 21, and the interior of the flange 331 is hollow and allows the transmission shaft 23 to pass through. At least a portion of the flange 331 is clearance-fitted with the transmission shaft 23 to form an installation gap, within which the magnetofluid 32 is disposed. The flange cover 332 may cover the flange 331, and the interior of the flange 331 is hollow to allow the transmission shaft 23 to pass through. The transmission shaft 23 passes through the flange 331 and the flange cover 332 to be directly or indirectly connected to the drive element 31. In order to reduce the friction between the transmission shaft 23 and the flange assembly 33 when the transmission shaft 23 rotates, the flange 331 is also formed with a mounting cavity for accommodating the bearing 333. The transmission shaft 23 passes into the mounting cavity of the flange 331 and connects with the bearing 333. The other parts of the transmission shaft 23 are clearance-fitted with the flange 331 and the flange cover 332, so that the friction between the transmission shaft 23 and the flange assembly 33 when the transmission shaft 23 rotates is greatly reduced.

[0048] Reference Figure 7 The transmission method between the drive component 31 and the transmission shaft 23 can be a belt drive. Specifically, the drive component 31 can be a servo motor. The output shaft of the drive component 31 is fixedly fitted with a drive wheel 311, and the transmission shaft 23 is fixedly fitted with a synchronous wheel 34. The drive wheel 311 and the synchronous wheel 34 are connected by a transmission belt. When the output shaft of the drive component 31 rotates, the drive wheel 311 drives the synchronous wheel 34 to rotate through the belt drive. The synchronous wheel 34 drives the transmission shaft 23 to rotate synchronously, thereby driving the transmission roller 22 to rotate.

[0049] In this embodiment, one driving element 31 can be used to drive only one transmission shaft 23 to rotate, or one driving element 31 can be used to drive multiple transmission shafts 23 to rotate. In a preferred embodiment, one driving element 31 drives multiple transmission shafts 23 to rotate. Specifically, multiple transmission shafts 23 can each be fixedly fitted with a synchronous pulley 34, and adjacent synchronous pulleys 34 can be connected via a transmission belt 35. A number of synchronous pulleys 34 are not only connected to adjacent synchronous pulleys 34, but also to the driving pulley 311 via the transmission belt 35. The driving element 31 drives the synchronous pulleys 34 connected to the driving pulley 311 to rotate via the driving pulley 311, and the synchronous pulleys 34 drive adjacent synchronous pulleys 34 to rotate via belt drive, so that multiple synchronous pulleys 34 can rotate synchronously under the drive of the driving element 31.

[0050] In this embodiment, the transmission assembly 2 includes four transmission rollers 22, each of which is equipped with a transmission shaft 23 fitted with a synchronous pulley 34. The transmission shafts 23 on the four transmission rollers 22 can be a first transmission shaft 23a, a second transmission shaft 23b, a third transmission shaft 23c, and a fourth transmission shaft 23d, arranged sequentially. The synchronous pulley 34 on the second transmission shaft 23b is connected to the synchronous pulley 34 on the first transmission shaft 23a by a transmission belt 35, and the synchronous pulley 34 on the third transmission shaft 23c is connected to the synchronous pulley 34 on the fourth transmission shaft 23d by a transmission belt 35. Furthermore, the synchronous pulleys 34 on the second transmission shaft 23b, the synchronous pulleys 34 on the third transmission shaft 23c, and the drive pulley 311 are connected by a transmission belt 35. When the driving component 31 drives the drive wheel 311 to rotate, the drive wheel 311 drives the synchronous wheel 34 on the second transmission shaft 23b and the synchronous wheel 34 on the third transmission shaft 23c to rotate. The synchronous wheel 34 on the second transmission shaft 23b drives the synchronous wheel 34 on the first transmission shaft 23a to rotate, and the synchronous wheel 34 on the third transmission shaft 23c drives the synchronous wheel 34 on the fourth transmission shaft 23d to rotate, so that the first transmission shaft 23a, the second transmission shaft 23b, the third transmission shaft 23c and the fourth transmission shaft 23d can rotate synchronously.

[0051] During transmission, insufficient tension in the transmission belt 35 can lead to poor transmission performance between adjacent synchronous pulleys 34. To ensure effective transmission between adjacent synchronous pulleys 34, a tensioning pulley 211 can be installed on the support bracket 21. The tensioning pulley 211 is used to tension the transmission belt 35 connecting adjacent synchronous pulleys 34, thus ensuring effective transmission between them. Alternatively, the tensioning pulley 211 may not be installed in the transmission belt 35 connecting the driving pulley 311 and the corresponding synchronous pulley 34; instead, the driving pulley 311 can be used to tension the transmission belt 35. Alternatively, the tensioning pulley 211 can be used to tension the transmission belt 35 connecting the driving pulley 311 and the corresponding synchronous pulley 34, as needed.

[0052] In other embodiments, the transmission method between the drive member 31 and the transmission shaft 23 may not be belt drive, but may be chain drive, gear drive or other transmission methods.

[0053] In this application, a transmission roller 22 is provided with a transmission shaft 23 at both ends. The transmission shaft 23 at one end can be connected to the drive wheel 311 of the drive member 31 through a synchronous pulley 34, while the synchronous pulley 34 on the transmission shaft 23 at the other end can be connected to the adjacent synchronous pulley 34 through a transmission belt 35 without being connected to the drive member 31. That is, the drive member 31 can be provided only at one end of the transmission roller 22 and drive the corresponding transmission shaft 23 to rotate.

[0054] Reference Figure 4 A transmission component 2 and a drive component 3 can form a transmission module 4. The transmission module 4 has multiple rotatable transmission rollers 22, which can drive the perovskite product to move a certain distance. Multiple transmission modules 4 can be arranged adjacent to each other within the transfer chamber 1, and these multiple transmission modules 4 are used together to transfer the perovskite product. For example, three transmission modules 4 can be arranged as a first transmission module 4a, a second transmission module 4b, and a third transmission module 4c. The first transmission module 4a is adjacent to the opening 121 and is used to receive and support the perovskite product entering the transfer chamber 1 through the opening 121. The third transmission module 4c is adjacent to the outlet 123 and is used to move the perovskite product out of the transfer chamber 1 through the outlet 123. The second transmission module 4b is located between the first transmission module 4a and the third transmission module 4c and is used to move the perovskite product from the first transmission module 4a to the third transmission module 4c.

[0055] During the transfer of the perovskite product, the perovskite product can remain stationary after moving to the target position in the transfer chamber 1, at which point the drive unit 31 stops. The target position can be a predetermined position of the perovskite product during the drying and crystallization process. A vacuum generator connected to the transfer chamber 1 evacuates the containing space 11 to perform vacuum drying and crystallization of the perovskite product. The transmission module 4 continues to drive the perovskite product to move it out of the transfer chamber 1 after drying and crystallization. By using a vacuum generator to evacuate the containing space 11 within the transfer chamber 1, the perovskite product can undergo a vacuum drying and crystallization process within the transfer chamber 1, serving as a vacuum drying process segment. This allows the perovskite wafer fabrication device of this application to function as a vacuum drying process segment for perovskite products in addition to the perovskite product transfer process, effectively simplifying the structure of the perovskite battery production line. The vacuum generator can be a vacuum pump.

[0056] The perovskite wafer transfer device of this application can be located between multiple process stages in the production of perovskite solar cells. For example, the opening 121 of the transfer chamber 1 is adjacent to the previous process stage. The perovskite product processed in the previous process stage is moved into the transfer chamber 1, and the outlet 123 of the transfer chamber 1 can be adjacent to the next process stage so that the perovskite product can move from the transfer chamber 1 to the next process stage for subsequent processing. Therefore, the perovskite product can be freely transferred between multiple process stages, greatly improving the transfer efficiency of the perovskite product.

Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
