Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic equipment technology, and relates to a transfer mechanism, specifically a material transfer mechanism for a perovskite battery coating crystallization annealing furnace. Background Technology

[0002] Perovskite solar cells are thin-film solar cells that utilize perovskite-type organometal halide semiconductors as photoelectric conversion materials. They generally include a substrate, a conductive material layer, a first carrier transport layer, a perovskite layer, a second carrier transport layer, and a top electrode layer. The layers on the substrate can be defined as coatings of the perovskite solar cell. Improving the performance of perovskite solar cells relies heavily on the crucial step of annealing. Annealing plays a vital role in perovskite solar cell fabrication, effectively removing residual solvents from the fabrication process and reducing the negative impact of these impurities on cell performance. It also stabilizes the crystal structure of the cell, ensuring material consistency and reliability, thereby improving the overall performance of the cell. Furthermore, annealing significantly increases electron mobility within the perovskite material, directly affecting the cell's photoelectric conversion efficiency. Therefore, annealing can further optimize the structure and properties of perovskite materials, leading to the fabrication of perovskite solar cells with high conversion efficiency and strong stability.

[0003] Chinese invention patent application number 201520954305.6 discloses a heating and slow cooling annealing furnace, which includes: a front pushing device, a front chamber of the heating and slow cooling furnace, a middle portal bag of the heating and slow cooling annealing furnace, a rear chamber of the heating and slow cooling annealing furnace, and a rear discharge platform arranged sequentially. The front chamber, the middle portal bag, and the rear chamber of the heating and slow cooling annealing furnace are connected in sequence. Furthermore, this application uses a chain-type power transmission system to transmit power. The transmission system rotates in both directions, driving a long push rod and a short push rod to move back and forth respectively. The short push rod is used for feeding material into the front chamber when the pushing platform is lowered, and the long push rod is used to push the material from the front chamber to the rear chamber when the pushing platform is raised. This transmission method has low precision and is not suitable for conveying materials for perovskite solar cells. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing a material transfer mechanism for a perovskite battery coating crystallization annealing furnace.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a material transfer mechanism for a perovskite battery coating crystallization annealing furnace, comprising:

[0006] A support assembly, comprising two parallel and spaced-apart receiving support frames and a plurality of connecting profiles spaced-apart between the two receiving support frames, the connecting profiles being perpendicular to the receiving support frames;

[0007] A power unit, which is used to output power;

[0008] The transmission assembly includes two sets of feed rollers rotatably mounted on the inner side of each of the receiving support frames and in the same horizontal plane, a feed roller shaft rotatably mounted on the two receiving support frames, two second transmission gears mounted at the ends of the feed roller shafts and spaced apart, and a first transmission belt connecting the power assembly and one of the second transmission gears. Each set of feed rollers includes a plurality of feed roller units spaced apart.

[0009] The transmission assembly also includes multiple second transmission belts that connect two adjacent feed roller units or connect the feed roller unit to another second transmission gear.

[0010] Optimally, the support assembly further includes adapter blocks installed at both ends of each of the connecting profiles, the connecting profiles being mounted on the inner sides of the two receiving support frames via the adapter blocks.

[0011] Furthermore, the support assembly also includes support connectors installed at both ends of each of the receiving support frames and cover plates installed on the outer side of each of the receiving support frames.

[0012] Optimally, the power assembly includes a mounting base disposed below the support assembly, a drive motor mounted on the mounting base, and a first transmission gear mounted on the output shaft of the drive motor, wherein the first transmission belt connects the first transmission gear and the second transmission gear.

[0013] Optimally, the material conveying roller unit includes a material conveying shaft rotatably mounted on and passing through the receiving support frame, a material conveying bushing sleeve sleeved on the material conveying shaft and located inside the receiving support frame, and two third transmission gears mounted on the material conveying shaft and housed within the receiving support frame.

[0018] Figure 2 for Figure 1 Side view. Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] like Figure 1 and Figure 2 The material transfer mechanism of the perovskite battery coating crystallization annealing furnace shown mainly includes a supporting component 1, a power component 2, and a transmission component 3.

[0021] The support assembly 1 includes two parallel and spaced-apart receiving support frames 10 and multiple spaced-apart connecting profiles 12 connected between the two receiving support frames. The connecting profiles 12 are perpendicular to the receiving support frames 10. The receiving support frames 10 serve to support the material transfer mechanism of the entire perovskite battery coating crystallization annealing furnace. Therefore, materials and structures with high load-bearing capacity, high temperature resistance, and high deformation resistance are selected. The two opposite sides (defined as outer sides) of the two receiving support frames 10 are recessed inward to form receiving spaces (the two facing sides are defined as inner sides). In this embodiment, the support assembly 1 also includes adapter blocks 13 installed at both ends of each connecting profile 12. The connecting profiles 12 are installed on the inner sides of the two receiving support frames 10 through the adapter blocks 13, thereby keeping the two receiving support frames 10 parallel and forming a frame structure with high load-bearing capacity with the connecting profiles 12 and the receiving support frames 10. It should be noted that the position of the connecting profiles 12 needs to be slightly lower to avoid affecting the normal operation of the transmission assembly 3. The support assembly 1 also includes support connecting seats 14 installed at both ends of each receiving support frame 10 and cover plates 11 installed on the outer side of each receiving support frame 10. The support connecting seats 14 can be used to securely install the material transfer mechanism of the perovskite battery coating crystallization annealing furnace onto other structures. A relatively sealed receiving space is formed between the cover plate 11 and the receiving support frame 10 to accommodate part of the structure of the transmission assembly 3.

[0022] The power assembly 2 is used to output power to drive the transmission assembly 3. It includes a mounting base 21 located below the support assembly 1 (and...). Figure 1 The drive motor 22 (with its output shaft passing through the mounting base 21) is mounted on the mounting base 21 in the opposite direction, and the first transmission gear 23 is mounted on the output shaft of the drive motor 22, so that when the drive motor 22 is working, it can drive the first transmission gear 23 to rotate synchronously.

[0023] The transmission assembly 3 includes two sets of feed roller groups rotatably mounted on the inner side of each receiving support frame 10 and in the same horizontal plane (each set of feed roller groups includes multiple feed roller units 34 spaced apart and in the same horizontal plane; in this embodiment, each set of feed roller groups includes six feed roller units 34); a feed roller shaft 31 rotatably mounted on the two receiving support frames 10 (the feed roller shaft 31 is perpendicular to the receiving support frame 10 and passes through the two receiving support frames 10, such that both ends of the feed roller shaft 31 are located within the aforementioned receiving space); two second transmission gears 32 spaced apart and mounted on the ends of the feed roller shaft 31 (the two second transmission gears 32 are spaced apart and located within the receiving space); and a first transmission belt 33 connecting the power assembly 2 and one of the second transmission gears 32; specifically, the first transmission belt 33 connects the first transmission gear 23 and one second transmission gear 32 (in this embodiment, the first transmission belt 33 connects the second transmission gear 32 located on the inner side, such as...). Figure 2 (As shown). In this embodiment, the transmission assembly 3 further includes connecting two adjacent feed roller units 34 or connecting the feed roller unit 34 with another second transmission gear 32 (the second transmission gear 32 located on the outer side, such as...). Figure 2 (As shown) multiple second drive belts 37; specifically, there are six second drive belts 37, and their connection method is as follows Figure 2 As shown.

[0024] In this embodiment, the feeding roller unit 34 includes a feeding shaft 341 rotatably mounted on and passing through the receiving support frame 10 (rotatability is conventional, such as through bearing connection, as above), a feeding bushing 342 sleeved on the feeding shaft 341 and located inside the receiving support frame 10 (no relative rotation occurs between the feeding bushing 342 and the feeding shaft 341), and two third transmission gears 343 mounted on the feeding shaft 341 and housed within the receiving support frame 10 (i.e., within the receiving space) (the two third transmission gears 343 of each feeding roller unit 34 correspond to the two second transmission gears 32). A second transmission belt 37 connects two adjacent third transmission gears 343 or connects a third transmission gear 343 to another second transmission gear 32, thereby achieving synchronous rotation of multiple feeding roller units 34 (e.g., ...). Figure 2 (As shown). In use, the tooling carrying the material is placed on two sets of mating conveyor bushings 342. When the conveyor bushings 342 work, they drive the tooling carrying the material to move forward synchronously (it can be used in places such as annealing furnaces).

[0025] In this embodiment, the transmission assembly 3 further includes a tension adjustment unit 36 ​​(located within the receiving space) mounted on the receiving support frame 10 and correspondingly abutting against the second transmission belt 37. Specifically, the tension adjustment unit 36 ​​includes a carrier plate 361 mounted on the receiving support frame 10, an adjusting threaded rod 364 rotatably inserted into the carrier plate 361 (when the adjusting threaded rod 364 is rotated, its depth within the carrier plate 361 can be adjusted), a rotating member 362 slidably mounted on the carrier plate 361 and connected to the adjusting threaded rod 364 (the carrier plate 361 has a through slot, the rotating member 362 has a protrusion embedded in the slot and a rotating part that can rotate relative to the protrusion (e.g., the rotating member 362 is an inner connecting block and an outer circular block connected by a central shaft, the inner connecting block has a protrusion, and the outer circular block is a rotating part or has a rotating part), and the adjusting threaded rod 364. The threaded connection extends through the protrusion and is threaded to it, so that when the adjusting threaded rod 364 is rotated, the rotating part 362 can be driven to slide up and down relative to the carrier plate 361 simultaneously. The adjusting gear 363, sleeved on the rotating part 362, abuts against the second transmission belt 37. At this time, the adjusting gear 363 is sleeved on the aforementioned rotating part and rotates synchronously with it. This allows for a slight change in the position of the adjusting gear 363 relative to the second transmission belt 37, thereby adjusting its tension. This further ensures the synchronicity of the movement of the multiple conveying roller units 34, enabling them to move the material smoothly forward when conveying materials (the material can be placed on a tooling, which is then placed on the transmission assembly for conveying). Figure 1 The state in the image is the opposite of the state in actual use.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
