Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic cells, and in particular to a photovoltaic cell displacement clamping device. Background Art

[0002] Laser scribing of perovskite cells is one of the key steps in the manufacturing process of perovskite solar cells, and is mainly used to construct the series circuit of the cell. Laser scribing usually involves fine scribing of different layers of the perovskite cell using laser etching technology. These layers may include FTO conductive glass (P1), perovskite layer (P2), and gold-plated or silver-plated materials (P3). The purpose of scribing is to divide the cell area, thereby connecting multiple battery cells in series to increase the voltage. High-precision laser scribing is crucial for the mass production of large-format perovskite cells, especially when forming a sub-cell series structure, different film layers need to be precisely etched at different positions, which requires that the laser process, system stability and accuracy must meet extremely high standards.

[0003] The laser scribing process for perovskite cells requires shifting the perovskite cells between various stations, including loading, alignment, scribing, and unloading. During this shifting process, the cells must be protected from distortion and flatness, while maintaining precise positioning. Currently, conventional methods use simple conveyor belts to shift photovoltaic cells, but this fails to guarantee smoothness and positional accuracy, compromising the accuracy of subsequent laser scribing and hindering the precise etching of perovskite cells.

Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0055] The shifting device of the existing laser scribing production line cannot guarantee the flatness and position accuracy of the battery, which affects the accuracy of subsequent laser scribing and is not conducive to the precise etching of perovskite batteries.

[0056] In order to solve the above problems, the applicant has developed a shifting jaw device, which can be used in the laser scribing production line of perovskite cells to realize the shifting of perovskite cells in different stations such as loading station, alignment station, scribing station, and unloading station. During the shifting process, it can prevent the battery from being twisted and deformed, ensure the flatness and position accuracy of the battery, help to improve the accuracy of subsequent laser scribing, and help to accurately etch the perovskite cell.

[0057] Specifically, see Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of the shifting jaw device of the present application.

[0058] like Figure 1 As shown, the shifting jaw device includes a fixed plate 10 and two jaw mechanisms 20 arranged on the fixed plate 10 at intervals along the x-axis direction.

[0059] It can be understood that the two clamping mechanisms 20 spaced apart in the x-axis direction can clamp the two ends of the photovoltaic cell during the displacement process, thereby ensuring the stability of the photovoltaic cell during the displacement process and preventing the photovoltaic cell from being twisted and bent.

[0060] It should be noted that in some scenarios where the size of the photovoltaic cells is smaller, only one clamping mechanism 20 arranged in the middle of the photovoltaic cell can be provided; or, in other application scenarios, more than two clamping mechanisms 20 can be provided, as long as the consistency of each clamping mechanism 20 is ensured, and the effect of this embodiment can be achieved.

[0061] The structure of the clamping mechanism 20 of this embodiment is described in detail below. Figures 2 to 4 , Figure 2 This is a schematic diagram of the three-dimensional structure of an embodiment of the clamping mechanism of the present application. Figure 3 This is a front view structural diagram of an embodiment of the clamping mechanism of the present application.

[0062] like Figures 2 to 4 As shown, the clamping mechanism 20 includes a Z-axis clamping unit 200 , a fixed clamping block 300 and a movable clamping block 400 .

[0074] It should be noted that the Y-axis displacement unit 500 in this embodiment adopts a cylinder structure. In other embodiments, the Y-axis displacement unit 500 may also adopt other telescopic structures, such as a hydraulic cylinder, a screw 703 and a nut 704, etc., which can also achieve the effect of this embodiment.

[0075] In order to make the height of the clamping mechanism 20 adjustable and help keep the clamping mechanisms 20 in the same plane, the clamping mechanism 20 in this embodiment further includes a Z-axis displacement unit 700 and a fixing bracket 800.

[0076] The Z-axis displacement unit 700 is arranged on the fixed plate 10 . The Z-axis displacement unit 700 includes a Z-axis slider 701 located at a working end. The Z-axis displacement unit 700 is used to drive the Z-axis slider 701 to move along the Z-axis.

[0077] The fixing bracket 800 is arranged on the Z-axis slider 701 , and the Y-axis cylinder 502 is arranged on the fixing bracket 800 .

[0078] Specifically, in this embodiment, the Z-axis displacement unit 700 can be arranged on the fixed plate 10 through the mounting seat 900 , and the first sliding groove 901 and the second sliding groove 902 are arranged on the side of the mounting seat 900 facing away from the fixed plate 10 .

[0079] The Z-axis displacement unit 700 may include a Z-axis motor 702, a screw 703, and a nut 704. The Z-axis motor 702 is mounted on a mounting base 900; the screw 703 extends along the Z-axis and is disposed within a first slot 901. The screw 703 is connected to the output end of the Z-axis motor 702; and the nut 704 is slidably disposed within the first slot 901 and is threadedly engaged with the screw 703.

[0083] The shifting operation of the shifting clamping device based on this embodiment can be as follows: adjust each clamping mechanism 20 to the same plane through the Z-axis displacement unit 700; control the movable clamping block 400 to move away from the fixed clamping block 300 through the Z-axis clamping unit 200; control the movement of the Z-axis clamping unit 200 through the Y-axis displacement unit 500, so that the photovoltaic cell is located between the fixed clamping block 300 and the movable clamping block 400; control the movable clamping block 400 to approach the fixed clamping block 300 through the Z-axis clamping unit 200, and the movable clamping block 400 and the fixed clamping block 300 cooperate to clamp the photovoltaic cell; after the workpiece is transferred to the right position, control the movable clamping block 400 to move away from the fixed clamping block 300 through the Z-axis clamping unit 200 to release the photovoltaic cell; control the Z-axis clamping unit 200 to reset through the Y-axis displacement unit 500.
