[0002] Photovoltaic cells are one of the key components of solar photovoltaic power generation systems, which can convert sunlight into electrical energy. The core of photovoltaic cells is semiconductor materials, such as silicon. When sunlight shines on the cells, the semiconductor materials absorb photons and generate electron-hole pairs. These electrons and holes are separated under the action of the electric field inside the semiconductor. The electrons move to the negative electrode and the holes move to the positive electrode, thus forming an electric current. This process directly converts light energy into electrical energy and generates direct current. The production and processing of photovoltaic cells mainly includes the following steps: silicon wafer cleaning and texturing, diffusion and bonding, plasma etching, removal of phosphosilicate glass, PECVD (plasma enhanced chemical vapor deposition), screen printing, drying and sintering, detection and classification; Photovoltaic cells need to be loaded in batches in multiple processing steps.

The square push plate 503 is pushed toward the layered plate 401 by the electric push rod 502, and the movement of the square push plate 503 drives the hollow air cushion on one side. The hollow air cushion 506 moves with the arc connecting rod 504 at the top, and when the hollow air cushion 506 moves to contact the side of the photovoltaic cell, it begins to elastically push the photovoltaic cell. At the same time, the hollow air cushion 506 is gradually compressed by the pushing of the square push plate 503 and the photovoltaic cell. When the hollow air cushion 506 is compressed, the air inside is quickly discharged to the outside through the exhaust circular hole 507. At the same time, the return spring 508 inside the hollow air cushion 506 is also compressed. When the hollow air cushion 506 is compressed, the round through rod 509 running through the inside is pushed and moved toward the square push plate 503. By setting a hollow air cushion 506 of elastic material on the square push plate 503 and the photovoltaic cell to push, by setting a through rod 509 inside the hollow air cushion 506 to penetrate the square push plate 503 and another through rod 509 inside the hollow air cushion 506 The round through rod 509 on one side is used to fix the shape of the hollow air cushion 506.

When the electric push rod 502 drives the square push plate 503 to move back to the outside and does not push the photovoltaic cell sheet sideways, the return spring 508 inside the hollow air cushion 506 loses its pushing force and pushes the hollow air cushion 506 to expand through the stretching force. By arranging multiple return springs 508 inside the hollow air cushion 506, the hollow air cushion 506 is expanded and restored to its initial state through the stretching force.When the photovoltaic cell piece moves up to a height that is flush with the loading height, the motor 602 is started to drive the threaded long rod 601 to rotate. When the threaded long rod 601 rotates, it drives the sleeve long plate 605 that is threadedly matched with it and is penetrated by the limited long rod 606 to move. When the sleeve long plate 605 moves, it pushes the photovoltaic cell piece on the small roller 404 to move to the processing area for loading. When the sleeve long plate 605 moves, it drives the trapezoidal scraper block 608 at the bottom to move. When the trapezoidal scraper block 608 moves, the bottom surface is always in contact with the top surface of the layered plate 401. The moving trapezoidal scraper block 608 scrapes and cleans the top surface of the layered plate 401. When the trapezoidal scraper block 608 moves, it drives the outer The side brush 609 and the fan-shaped scraper 610 move together. The side brush 609 rubs and cleans the surface of the small roller 404 as the trapezoidal scraper block 608 moves. The fan-shaped scraper 610 intermittently enters the outer oblique circular hole 402 and rubs against the inner wall of the outer oblique circular hole 402 as the trapezoidal scraper block 608 moves. When the fan-shaped scraper 610 moves in the outer oblique circular hole 402, it drives the thorn-shaped scraper block 611 on the inner side surface to scrape and clean the inner wall of the outer oblique circular hole 402. By opening a plurality of dust-passing circular holes 612 at the position where the thorn-shaped scraper block 611 is not provided on the surface of the fan-shaped scraper 610, it is convenient for dust to pass through while reducing the surface area of ​​the inner side surface of the fan-shaped scraper 610.

[0014] When the present invention is in operation, a single photovoltaic cell is inserted into the stratification device 4. After the insertion is completed, the side pushing device 5 pushes the photovoltaic cell on both sides of the stratification device 4 at the same time, so that the position correction of the photovoltaic cell will not be offset or misaligned. When the photovoltaic cell needs to be loaded, the side pushing of the photovoltaic cell is released by the side pushing device 5, and the curved connecting plate 2 is pushed upward by the hydraulic push rod 3 to move. The movement of the curved connecting plate 2 drives the stratification device 4 to move upward. The upward movement of the stratification device 4 drives the photovoltaic cell to move up to the height that is flush with the loading height. At this time, the photovoltaic cell is pushed into the processing area by the pushing device 6 for loading, and the single photovoltaic cell is placed on the small rollers 404 on the stratification plate 401 respectively. By setting multiple The layer plate 401 is used to place multiple stacked photovoltaic cells in layers for loading. The multiple outer oblique circular holes 402 on the layer plate 401 facilitate the passage of dust and other debris. By opening multiple outer oblique circular holes 402 on the layer plate 401, the residual dust and other debris gradually fall downward on the inner side of the concave bottom plate 1. When the photovoltaic cell is pushed by the pushing device 6 to move to the processing area, it drives the multiple small rollers 404 at the bottom to rotate together. By setting the small rollers 404, the layer plate 401 is separated from the photovoltaic cell by a distance to facilitate the movement and loading of the photovoltaic cell. When the small rollers 404 rotate, they drive the small thorn blocks 405 on the outer surface to rotate together. The small thorn blocks 405 move in the inner area of ​​the square small holes 403 at all times as the small rollers 404 rotate, so as to load the photovoltaic cell. After insertion, the photovoltaic cell placed on the small roller 404 can be corrected by the side push device 5, and the square push plate 503 is pushed toward the layered plate 401 by the electric push rod 502. The movement of the square push plate 503 drives the hollow air cushion 506 on one side and the arc-shaped connecting rod 504 on the top to move together. When the hollow air cushion 506 moves to contact the side of the photovoltaic cell, it begins to elastically push the photovoltaic cell. At the same time, the hollow air cushion 506 is gradually compressed by the push of the square push plate 503 and the photovoltaic cell. When the hollow air cushion 506 is compressed, the air inside is quickly discharged to the outside through the exhaust circular hole 507. At the same time, the return spring 508 inside the hollow air cushion 506 is also compressed. When the hollow air cushion 506 is compressed, it penetrates the inner The round through rod 509 at the top is pushed and moved in the direction of the square push plate 503, and a hollow air cushion 506 made of elastic material is set on the square push plate 503 and the photovoltaic cell to push, and a round through rod 509 is set inside the hollow air cushion 506 to penetrate the other side of the square push plate 503 to fix the shape of the hollow air cushion 506. The arc connecting rod 504 drives the side baffle 505 at one end to gradually move in the direction of the photovoltaic cell as the square push plate 503 moves, until it stops when it moves to contact the side of the photovoltaic cell, and side baffles 505 are set on both sides of the photovoltaic cell to be pushed for loading to resist and limit it. When the electric push rod 502 drives the square push plate 503 to move back to the outside and does not push the photovoltaic cell sideways,The return spring 508 inside the hollow air cushion 506 loses its pushing force and pushes the hollow air cushion 506 to expand through the stretching force. By arranging multiple return springs 508 inside the hollow air cushion 506, the hollow air cushion 506 is expanded and restored to its initial state through the stretching force. When the photovoltaic cell piece moves up to a height that is flush with the loading height, the motor 602 is started to drive the threaded long rod 601 to rotate. When the threaded long rod 601 rotates, it drives the sleeve-type long plate 605 that is threadedly matched with it and is penetrated by the limited long rod 606 to move. When the sleeve-type long plate 605 moves, it pushes the photovoltaic cell piece on the small roller 404 to move to the processing area for loading. When the sleeve-type long plate 605 moves, it drives the trapezoidal scraper block 608 at the bottom to move. When the trapezoidal scraper block 608 moves, the bottom surface is always in contact with the top surface of the layered plate 401 The moving trapezoidal scraper 608 scrapes and cleans the top surface of the layering plate 401. When the trapezoidal scraper 608 moves, it drives the outer side brush 609 and the fan-shaped scraper 610 to move together. The side brush 609 rubs and cleans the surface of the small roller 404 as the trapezoidal scraper 608 moves. As the trapezoidal scraper 608 moves, the fan-shaped scraper 610 intermittently enters the outer oblique circular hole 402 and rubs and contacts the inner wall of the outer oblique circular hole 402. When the fan-shaped scraper 610 moves in the outer oblique circular hole 402, it drives the thorn-shaped scraper 611 on the inner side surface to scrape and clean the inner wall of the outer oblique circular hole 402. By opening a plurality of dust-passing circular holes 612 at the position where the thorn-shaped scraper 611 is not set on the surface of the fan-shaped scraper 610, it is convenient for dust to pass through while reducing the surface area of ​​the inner side surface of the fan-shaped scraper 610.
