[0033] Research has revealed the following drawbacks of existing technologies: In the production and preparation of perovskite solar cells, multiple processes are required, necessitating material loading and unloading between these processes. To improve production efficiency and save space, multi-layer annealing furnaces are used to anneal the cell substrates. However, in the application of multi-layer annealing furnaces, multiple rollers are required to match the furnace. The rollers need to transport the cell substrates to a certain position before retrieving them. During transport, it is necessary to move the high-layer cell substrates to the low-layer positions for retrieval, or vice versa, resulting in slow loading and unloading speeds and low space utilization.
[0034] Therefore, how to solve the problems of slow loading and unloading speed and low space utilization is a technical problem that urgently needs to be solved in this field.
[0035] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.
[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0037] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0038] like Figures 1 to 2 As shown, some embodiments provide a loading and unloading mechanism, including: a substrate conveying device 2 and a lifting assembly 1, which is used to fix the substrate conveying device 2; the substrate conveying device 2 can move up and down on the lifting assembly 1 to change the vertical height of the substrate conveying device 2, so as to facilitate picking up or placing the battery substrate.
[0039] Please see Figure 1 The lifting assembly 1 includes: a bracket 11 with a linear guide rail 111 along its height direction; a drive module 12 located at the bottom of the bracket 11; and a transmission module 13 located on the bracket 11 and rotatably connected to the drive module 12. The drive module 12 drives the transmission module 13 to rotate, and the rotation of the transmission module 13 changes the vertical height of the substrate conveying device 2.
[0040] Please see Figure 1The up-and-down moving module 14 is connected to the transmission module 13, and the substrate conveying device 2 is mounted on the up-and-down moving module 14. The drive module 12 drives the transmission module 13 to rotate, so that the up-and-down moving module 14 moves up or down along the linear guide rail 111 to change the distance between the substrate conveying device 2 and the battery substrate. Specifically, the substrate conveying device 2 is fixed on the synchronous conveyor belt 133. The rotation of the synchronous conveyor belt 133 allows the substrate conveying device 2 to move up or down.
[0041] Please see Figure 1 The drive module 12 includes a dual-head servo motor 121, which is fixed at the bottom of the bracket 11. The output end of the dual-head servo motor 121 is connected to a drive shaft 123 through a reducer 122. The drive shaft 123 is rotatably connected to the transmission module 13. The drive shaft 123 is connected to both drive shafts of the dual-head servo motor 121. The drive shaft 123 is used to drive the first synchronous pulley 131 to rotate.
[0042] Please see Figure 1 The transmission module 13 includes: a pair of first synchronous pulleys 131, which are rotatably connected to the drive shaft 123; and a pair of second synchronous pulleys 132, which are rotatably connected to the top of the bracket 11. Among them, one first synchronous pulley 131 and one second synchronous pulley 132 on the same side form a group, that is, the first synchronous pulley 131 and the second synchronous pulley 132 on the same side of the bracket 11 are provided with synchronous conveyor belts 133. The vertical moving module 14 is horizontally fixed between the two synchronous conveyor belts 133, and the slide plate 141 is fixed between the two synchronous conveyor belts 133, and the vertical height of the fixing point is the same.
[0043] The following describes in detail how the synchronous conveyor belt 133 drives the slide plate 141 to move up or down. The dual-head servo motor 121 is configured to drive the drive shaft 123 to rotate. The drive shaft 123 will cause the first synchronous wheel 131 connected to it to rotate, thereby causing the synchronous conveyor belt 133 to rotate on the first synchronous wheel 131 and the second synchronous wheel 132, so that the up and down moving module 14 moves up or down along the linear guide rail 111.
[0044] The vertical moving module 14 includes: a slide plate 141, which is fixed on two synchronous conveyor belts 133. The slide plate 141 is fixed on the synchronous conveyor belts 133 by clamps. In addition, the slide plate 141 is provided with a slide groove 143, which is suitable for moving along the linear guide rail 111 through the slide groove 143. A bracket 142 is fixed on one side of the slide plate 141. The bracket 142 is suitable for fixing the substrate conveying device 2 and provides an installation platform for the substrate conveying device 2.
[0045] Please see Figure 2The support 11 is equipped with two pairs of limiting blocks 114. Each pair of limiting blocks 114 on the same side is positioned between the first synchronous pulley 131 and the second synchronous pulley 132. That is, the support 11 is equipped with limiting blocks 114 near the positions of the first synchronous pulley 131 and the second synchronous pulley 132. The limiting blocks 114 are used to allow the slide plate 141 to move on the synchronous conveyor belt 133 between the two limiting blocks 114. In addition, multiple position sensors 15 are fixed along the height direction of the support 11. Their height corresponds to the height of the battery substrate in the annealing furnace. This allows the position sensors 15 to transmit signals to the controller, which can receive the signals indicating the vertical height of the slide plate 141 at this time, which is also the height of the substrate conveying device 2.
[0046] To enhance the overall safety of the loading and unloading mechanism, a fall arresting chain 16 is installed at the top of the support 11, and a fall arresting hook 17 is installed on the slide plate 141. The fall arresting chain 16 and the fall arresting hook 17 are connected to prevent the slide plate 141 from falling. During maintenance, the fall arresting hook 17 can be hung on the fall arresting chain 16, which can prevent the slide plate 141 from suddenly falling and injuring the maintenance personnel below, and also prevent damage to the substrate conveying device 2 on the slide plate 141. To further enhance safety, multiple transverse reinforcing plates 112 are fixed on the support 11, and each transverse reinforcing plate 112 is provided with a pluggable blocking shaft 113. The slide plate 141 is provided with a stop hole 144. The blocking shaft 113 is configured to be inserted into the transverse reinforcing plate 112 through the stop hole 144 to prevent the slide plate 141 from falling.
[0047] Some embodiments provide a perovskite battery annealing production line, including: a transport chamber 3, a receiving chamber 4, and a loading and unloading mechanism 5 as described above; the loading and unloading mechanism 5 is disposed between the transport chamber 3 and the receiving chamber 4 or on both sides of the receiving chamber 4; wherein, the loading and unloading mechanism 5 is adapted to take the battery substrate out of the transport chamber 3 and send it into the receiving chamber 4, or take the battery substrate out of the receiving chamber 4.
[0048] In summary, the substrate conveying device 2 is mounted on the up-and-down moving module 14, allowing the drive module 12 to drive the transmission module 13 to rotate. The up-and-down moving module 14 moves along the linear guide rail 111 to the height of the specified layer in the annealing furnace, thereby shortening the distance between the substrate conveying device 2 and the battery substrate for material handling and loading / unloading, thus improving the loading and unloading speed.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
