[0002] Currently, perovskite solar cells require processes such as coating, drying, and annealing. Each process needs automated loading and unloading to connect. To improve annealing efficiency, the annealing furnace is designed as a multi-layer structure. However, loading and unloading in a multi-layer annealing furnace involves a height difference between the vertical and horizontal planes. To reduce the difficulty of loading and unloading, related technologies set up a centralized material handling port in the lower layer of the multi-layer annealing furnace. This results in a height difference between the vertical and horizontal planes of the solar cell substrate during loading and unloading, requiring the vertical adjustment of the solar cell substrate, which in turn affects the overall annealing efficiency.
[0003] Therefore, how to solve the low loading and unloading efficiency of multi-layer annealing furnaces is a technical problem that urgently needs to be solved in this field.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0037] Research has revealed the following drawbacks of existing technologies: Currently, perovskite solar cells require processes such as coating, drying, and annealing. Each process needs automated loading and unloading to connect. To improve annealing efficiency, the annealing furnace is designed as a multi-layer structure. However, loading and unloading in multi-layer annealing furnaces involves a height difference between the vertical and horizontal planes. To reduce the difficulty of loading and unloading, related technologies have set up a centralized material loading port in the lower layer of the multi-layer annealing furnace. This requires vertical adjustment of the solar cell substrate during loading and unloading. For example, while unloading is being done in the first layer, loading or unloading in other layers cannot be done, thus affecting the overall production efficiency.
[0038] Therefore, how to solve the low loading and unloading efficiency of multi-layer annealing furnaces is a technical problem that urgently needs to be solved in this field.
[0039] 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.
[0040] 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.
[0041] 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.
[0042] like Figures 1 to 3 As shown, some embodiments provide an annealing system, including: a base 1, a cleanroom enclosure 2, an annealing furnace 3, and a lifting robotic arm 6; the cleanroom enclosure 2 is disposed along the edge of the base 1, that is, the cleanroom enclosure 2 is fixed at the top edge of the base 1; the annealing furnace 3 is also disposed on the base 1, and is disposed at the center of the top surface of the base 1, the cleanroom enclosure 2 and the annealing furnace 3 abut against each other on both sides, specifically, the annealing furnace 3 includes at least two layers of annealing boxes stacked sequentially from bottom to top, and the doors 37 of the corresponding layers are respectively hinged to the side walls of the annealing boxes; a battery cell substrate transfer cavity 22 is formed between the two sides of the annealing furnace 3 and the cleanroom enclosure 2, and a lifting robotic arm 6 suitable for clamping the battery cell substrate is disposed in the battery cell substrate transfer cavity 22; two lifting robotic arms 6 are disposed inside the cleanroom enclosure 2 and located on both sides of the annealing furnace 3, and can be used to pick up or place the battery cell substrate from different height positions on both sides of the annealing furnace 3.
[0043] Please see Figure 2 The annealing furnace 3 has at least two layers of doors 37 on both sides of its furnace walls. Each layer of door 37 corresponds to a certain height of the annealing furnace 3, and each door 37 is driven to open and close by a corresponding drive module 38. After the door 37 of the corresponding layer is opened, a lifting robotic arm 6 extends into the annealing furnace 3 from the position of the door 37 to pick up or place the battery cell substrate. The drive module 38 includes, but is not limited to, mechanisms such as cylinders and motors that can drive the doors 37 to open; that is, the drive module 38 is cylinder-driven or motor-driven, etc.
[0044] Please see Figure 1 The cleanroom enclosure 2 is described in detail below. The cleanroom enclosure 2 is mainly used to improve the cleanliness of the working environment of the annealing furnace 3. In addition, multiple observation windows 21 are provided on the cleanroom enclosure 2. The main function of the observation windows 21 is to allow the experimenters to observe the difference between the battery cell substrate before and after annealing. The battery cell substrate is suitable for reaching the observation window 21 through the lifting robotic arm 6.
[0045] Please see Figure 1 The controller 4 is fixed on the base 1 by the mounting bracket 5. The output terminal of the controller 4 is electrically connected to the input terminal of the drive module 38. The controller 4 is adapted to drive the door 37 to open or close through the drive module 38. The controller 4 controls the drive module 38 of each layer individually. The opening and closing of the door 37 can be controlled by controlling the corresponding drive module 38 of each layer.
[0046] Please see Figures 2 to 3 The annealing furnaces 3 are stacked from bottom to top as follows: first annealing box 31, second annealing box 32, third annealing box 33, aisle box 36, fourth annealing box 34, and fifth annealing box 35. The doors 37 of the corresponding layers are respectively hinged to the side walls of the first annealing box 31, second annealing box 32, third annealing box 33, aisle box 36, fourth annealing box 34, and fifth annealing box 35. At least one aisle box 36 is provided between the annealing boxes. The aisle box 36 is used to temporarily store the battery cell substrate. In special cases, such as when the annealing time or annealing temperature does not meet the standards, the battery substrate needs to be annealed repeatedly. The aisle box 36 can temporarily store the battery substrate to be annealed.
[0047] Please see Figures 2 to 3 The annealing chamber is equipped with a heating element, which can be a hot plate type or a hot lamp type; wherein, at least two layers of the annealing chamber use the same heating element for heating; the hot plate type includes a heating plate 310, which is fixed in the annealing chamber; the hot lamp type includes a halogen heating lamp 39 and a hot air circulation pump 7, which are fixed in the annealing chamber.
[0048] In summary, by providing doors 37 on both sides of each annealing chamber and having the drive module 38 control the opening and closing of the doors 37, the lifting robotic arm 6 can simultaneously pick up or unload materials from both sides of the annealing furnace, shortening the annealing loading and unloading time and improving the battery annealing efficiency.
