Specific embodiments

[0036] The following will describe in detail the three embodiments of the present application with reference to the accompanying drawings.

[0037] The first embodiment:

[0038] Figures 1-10 It is shown that a laser scribing device for the production of perovskite photovoltaic modules includes a main body 1 of the laser scribing device installed on a rotating platform. Buffer zones and detection zones are respectively arranged at the front and rear ends of the main body 1 of the laser scribing device. A buffer loading component 2 is arranged in the buffer zone. A conveyor belt for conveying photovoltaic modules is arranged at the input end of the buffer loading component 2. In this embodiment, the conveyed photovoltaic modules are solar cells;

[0039] The buffer loading component 2 includes a lifting device 21. A movable end of the lifting device 21 is fixedly connected with a multi-layer bracket 22. A plurality of pairs of sub-sliding rails 23 for temporarily storing solar cells are installed on the multi-layer bracket 22. A movable end of the sub-sliding rail 23 is connected with a movable pallet 24. The sub-sliding rail 23 includes an electric guide rail. The movable ends of two sub-sliding rails 23 are respectively connected with two movable pallets 24. A fixed pallet 25 is connected between the fixed ends of a pair of sub-sliding rails 23. Clamping frames 26 are installed on both the sliding pallet 24 and the fixed pallet 25; The clamping frame 26 includes a clamping plate that can be lifted by an electric push rod. Through holes matching with the telescopic end of the electric push rod are opened on both the sliding pallet 24 and the fixed pallet 25. The fixed end of the electric push rod is installed at the bottom of the sliding pallet 24 or the fixed pallet 25. When the clamping plate rises, the solar cell panel is released. When the clamping plate descends, the solar cell panel is clamped;

[0040] When unloading or loading the solar cells from or onto the multi-layer bracket 22, the clamping plate on the movable pallet 24 descends to clamp the solar cells, while the clamping plate on the fixed pallet 25 rises to release the solar cells. When the movable pallet 24 moves, it can drive the solar cells to move; When the solar cells need to be fixed, the clamping plate on the fixed pallet 25 descends;

[0041] A docking and positioning component 3 matching with the buffer loading component is installed on the main body 1 of the laser scribing device. The docking and positioning component 3 includes a movable guide rail 31. A feeding plate 32 is installed at a movable end of the movable guide rail 31. An electric suction cup 322 is installed on the feeding plate 32. A positioning and calibration unit is used to calibrate whether the feeding plate 32 matches the fixed pallet 25. A positioning and calibration unit is installed on the feeding plate 32. The positioning and calibration unit includes a laser sensor. The laser sensor is used to detect whether the feeding plate 32 is aligned with the clamping frame 26 on the fixed pallet 25. When the laser sensor detects that the distance from the clamping frame 26 is the set distance, it is judged to be aligned. A suitable laser sensor in the prior art is selected by those skilled in the art for installation;

[0042] The feeding plate 32 includes a T-shaped beam 321 that moves through an electric guide rail. A plurality of pairs of pressure applicators are connected to the upper end of the T-shaped beam 321. The movable end of the pressure applicator is connected with an electric suction cup 322. A plurality of inverted T-shaped air channels are opened at the lower end of the T-shaped beam 321. The air outlet ends of the inverted T-shaped air channels are located on both sides of the lower region of the T-shaped beam 321. A micro air pump 323 communicating with the inverted T-shaped air channels is installed on the T-shaped beam 321. The micro air pump 323 is directly connected with the inverted T-shaped air channels by a conduit;

[0043] When the feeding plate 32 moves, the micro air pump can be turned on to make the inverted T-shaped air channels discharge air to clean the sundries on the grid plate;

[0044] The feeding plate 32 is used to input the solar cell into the main body 1 of the laser scribing device from the buffer area or output the solar cell from the main body 1 of the laser scribing device to the detection area;

[0045] An appearance detector is arranged in the detection area. The appearance detector includes an image acquisition unit and an image recognition unit;

[0046] A grille plate including a plurality of grille bars is arranged on the main body 1 of the laser scribing device. At least one side positioning structure is arranged inside the grille plate. The side positioning structure includes a lifting table 11. A bidirectional guide rail 12 is fixedly connected to the movable end of the lifting table 11. Clamping plates 13 are installed on both movable ends of the bidirectional guide rail 12. The bidirectional guide rail 12 includes two electric guide rails arranged in pairs; when the lifting table 11 rises, the bidirectional guide rail 12 rises to be close to the surface of the grille plate. When the clamping plates 13 are driven by the electric guide rails to move, the side ends of the solar cell are clamped. A pressure sensor is installed on the clamping plates 13.

[0047] The working process of this solution is as follows: The photovoltaic cell is sent into the buffer area through the conveyor belt. The lifting device 21 of the buffer loading assembly 2 drives the multi-layer bracket 22 to rise, so that each sub-slide rail 23 is placed with a photovoltaic cell. After the clamping frame 26 descends, it clamps the solar cell, completing the preliminary loading operation; The multi-layer bracket 22 loads multiple solar cells in batches. Every time a set number of solar cells are counted and loaded, this part of the solar cells is numbered as the same batch, and then the count is restarted;

[0048] When the main body 1 of the laser scribing device needs to be loaded, the multi-layer bracket 22 rises to make the designated sub-slide rail 23 flush with the loading end of the main body 1 of the laser scribing device. Then the movable end of the sub-slide rail 23 moves, so that the photovoltaic cell on it is sent onto the main body 1 of the laser scribing device and abuts against one end of the feeding plate 32. Then one end of the photovoltaic cell is adsorbed by the electric suction cup 322. Then the feeding plate 32 moves backward to completely pull the photovoltaic cell into the main body 1 of the laser scribing device, and the electric suction cup 323 releases the photovoltaic cell. Then the side clamping structure works, and a pair of clamping plates 13 clamp the side end of the photovoltaic cell to realize the positioning and calibration of the photovoltaic cell;

[0049] After the photovoltaic cell is placed accurately, laser scribing is carried out. During the laser scribing process, the pressure sensor on the clamping plate 13 monitors the clamping force and displacement conditions to ensure the accuracy and stability of the laser scribing. After the laser scribing is completed;

[0050] The rotating platform drives the main body 1 of the laser scribing device to rotate 180 degrees. At this time, the feeding plate 32 is located on the side of the solar cell away from the detection area. The feeding plate 32 abuts against the edge of the solar cell and the electric suction cup 322 is turned on to adsorb the solar cell. Then the feeding plate 32 moves to push the solar cell into the detection area;

[0051] After the solar cell is sent to the detection area, the solar cell is transported to the lower side of the appearance detector through a conveyor belt. The appearance detector performs image acquisition and image recognition to determine the appearance quality of the solar cell. The appearance detection by image recognition adopts the existing technology and will not be elaborated in detail in this solution;

[0052] If the appearance detection passes, the conveyor belt outputs the solar cell to the next process; if the appearance detection fails, the conveyor belt inputs the solar cell to the transfer area for further processing; during the whole process, the laser scribing equipment realizes the efficient and precise production of perovskite solar cells through accurate feeding, clamping, positioning and scribing operations.

[0053] The second implementation mode:

[0054] Figure 10 It is shown that the appearance detector is signal-connected to the buffer loading component 2. A temporary storage area is set at the output end of the appearance detector, and a buffer loading component 2 is arranged in the temporary storage area. After the laser scribing device main body 1 outputs a set number of photovoltaic modules in the same batch, an appearance detection is carried out. If the appearance detection passes, the subsequent photovoltaic modules in this batch are normally output after scribing, and the photovoltaic modules in the temporary storage area of this batch are output; if the appearance detection fails, the photovoltaic modules in the temporary storage area are input to the transfer area.

[0055] When the multi-layer bracket 22 of the buffer loading component 2 in the temporary storage area is at the set high point, it is used for the normal output of the photovoltaic modules that pass the appearance detection. When the multi-layer bracket 22 of the buffer loading component 2 in the temporary storage area is at the set low point, it is used to input the photovoltaic modules that fail the appearance detection into the transfer area.

[0056] The temporary storage area of this implementation mode realizes the flexible temporary storage and classification processing of photovoltaic modules. When the appearance detector detects that the quality of the photovoltaic modules in a certain batch meets the standard, the subsequent photovoltaic modules in this batch will be directly output after scribing, and at the same time, the photovoltaic modules temporarily stored in the temporary storage area are allowed to be normally output to the next process. This process ensures the smooth circulation of high-quality photovoltaic modules. When the appearance detector detects that the quality of the photovoltaic modules in a certain batch does not meet the standard, the system will input the photovoltaic modules in the temporary storage area into the transfer area for further quality inspection or processing.

[0057] The third implementation mode:

[0058] Figure 11 It is shown that a system of a laser scribing device for the production of perovskite photovoltaic modules includes a terminal processor, and a control module, a detection module, a data processing module and an alarm module are connected to the terminal processor;

[0059] The control module is used to control the main body 1 of the laser scribing device, the buffer feeding assembly 2 and the docking and positioning assembly 3 to work according to instructions;

[0060] The detection module is used to control the appearance detector to perform appearance detection. The detection module can obtain the detection results of the appearance detector in real time and transmit the results to the data processing module;

[0061] The data processing module is used to process the appearance detection results. The data processing module analyzes the detection results in detail to judge whether the photovoltaic module meets the quality standards;

[0062] The alarm module is used for alarming when the appearance detection fails. If the appearance detection fails for a set number of times, the main body 1 of the laser scribing device will be paused and an alarm will be issued.

[0063] Before starting the scribing work for each batch of photovoltaic modules, a set detection sequence number is randomly generated; after the photovoltaic modules corresponding to the detection sequence number of each batch pass the detection, a new detection sequence number for the next processing batch queue is regenerated;

[0064] When the appearance detection fails, the photovoltaic module and other photovoltaic modules stored in the temporary storage area of this batch are input to the transfer area. At the same time, the photovoltaic module being laser scribed and a set number of photovoltaic modules in the buffer area are regrouped into a new batch, and a new detection sequence number is generated, realizing regrouping and detection sequence number generation after the appearance detection fails;

[0065] For example: if the number of photovoltaic modules in each batch is 6 and the detection sequence number of the current batch is 3, only the 3rd photovoltaic module in this batch is detected. If its detection fails, the photovoltaic module and the other photovoltaic modules of this batch in the temporary storage area are input to the transfer area. At the same time, the 4th photovoltaic module being laser scribed and the subsequent 5 unscribed photovoltaic modules in the buffer area are regrouped into a new batch and a new detection sequence number is generated; the 1st photovoltaic module in the new batch is the 4th photovoltaic module being laser scribed in the original batch;

[0066] In this way, the system can quickly respond to the results of the appearance detection, isolate the unqualified photovoltaic modules, and regroup and detect the remaining photovoltaic modules to ensure the continuity of the production process and the stability of the product quality.

[0067] This embodiment can achieve the efficient and automated production of perovskite photovoltaic modules. Through the coordinated control of the terminal processor, this system ensures the close cooperation between each module, thus improving the production efficiency.

[0068] The system has the function of randomly generating set detection serial numbers. Before starting the scribing work for each batch of photovoltaic modules, the system will randomly generate a detection serial number and correspond it to a certain photovoltaic module in this batch. If the appearance inspection of this photovoltaic module passes, the system will regenerate the processing batch queue and continue to process other photovoltaic modules in this batch. This random inspection method helps to timely discover potential quality problems.

[0069] In summary, the laser scribing equipment and system provided by the present invention for the production of perovskite photovoltaic modules achieve the efficient and automated production of perovskite photovoltaic modules through precise control, real-time monitoring, and random inspection methods.

[0070] Combined with the current actual requirements, the above implementation manner adopted by this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
