Description

Technical Field

[0001] The present invention relates to the technical field of solar cell production, and in particular to a solar cell production device. Background Art

[0002] Solar cell production refers to the process of converting photovoltaic silicon wafers through a series of processes to produce solar cells that convert solar energy into electricity. Solar cells are the core components of solar photovoltaic power generation systems. Their manufacturing process and technical level directly affect the conversion efficiency, stability and cost of photovoltaic power generation systems.

[0003] There are still the following defects in specific use:

[0004] 1. Internal stress may cause microcracks on the surface or inside of the cell. These microcracks may expand during subsequent processing or use, eventually leading to cell breakage or failure. Internal stress will reduce the overall mechanical strength of the cell, making it more susceptible to breakage during subsequent processing, transportation or installation. At the same time, the presence of microcracks and internal stress may affect the electrical performance of the cell, such as reducing the photoelectric conversion efficiency and increasing the series resistance, thereby affecting the overall performance of the solar cell module.

[0005] 2. Furthermore, a worn laser head cannot generate a high-quality laser beam, resulting in reduced cutting or processing accuracy, burrs, rough edges or irregular shapes, and a worn laser head may take longer to complete the same task, thereby reducing production efficiency.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The present invention utilizes the adapter rod and the brush plate to cooperate with each other. Through circular motion, the multi-range scraping mechanism can more comprehensively contact the surface of the battery cell and effectively remove tiny silicon dust, debris and other impurities. This motion mode can cover every area of ​​the battery cell, ensuring more thorough cleaning. Secondly, during the slicing process, some tiny scratches or defects may appear on the surface of the battery cell. The multi-range scraping mechanism with circular motion can help reduce the impact of these defects. By effectively removing surface impurities, the defect rate of the battery cell surface is reduced, and the quality of the final product is improved. Secondly, by completing the cleaning step at the same time as slicing, the process time of subsequent separate cleaning is reduced. This integrated processing method can significantly improve Improve the efficiency of the entire production line and shorten the production cycle. In addition, the multi-range scratching mechanism can prevent debris from slicing and accumulating on the equipment, which helps reduce equipment wear and maintenance requirements and extend the service life of the equipment. In addition, if the silicon dust generated during the slicing process is not cleaned in time, it will not only affect the performance of the battery cell, but also pollute the workshop environment. The circular motion multi-range scratching mechanism can effectively control dust, keep the working environment clean, and reduce harm to personnel and the environment. Finally, by performing real-time cleaning during the slicing process, it can be ensured that each battery cell undergoes the same treatment, ensuring product consistency and reliability, which is especially important for mass production of high-quality solar cells.

[0024] (2) The present invention utilizes the barrier buckle and the hammer ball to cooperate with each other. The knocking mechanism can produce tiny deformations or indentations on the surface of the battery cell, which may help to improve the adhesion and uniformity of subsequent processes (such as metallization, electrode printing, etc.). Secondly, the knocking mechanism can, in some cases, enhance the overall mechanical strength of the material by introducing microstructural changes, increase the durability and life of the battery cell, and at the same time, the knocking mechanism may help to change the physical and chemical properties of the battery cell surface, making it more active, thereby improving the effects of subsequent process steps (such as coating, plating, etc.). Furthermore, the knocking mechanism can help expose and remove tiny defects on the surface of the battery cell, such as cracks or holes, which helps to improve the quality and performance of the final product. At the same time, during the slicing process, Battery cells may stick together due to static electricity or other reasons. The tapping mechanism can help separate these stuck battery cells to ensure that they can be smoothly transported and handled. Furthermore, the tapping mechanism can shake off debris and dust on the surface and edges of the battery cells to keep the battery cells clean, which is very important for quality control of subsequent processes because debris and dust may affect the performance of the battery cells. In addition, during the slicing process, the battery cells may warp due to internal stress. The tapping mechanism can help release this stress and keep the battery cells flat, which helps to improve the accuracy of subsequent processing and assembly. Finally, the tapping mechanism can help eliminate or reduce static electricity accumulation on the surface of the battery cells, further reducing the risk of battery cell adhesion and reducing quality problems caused by static electricity.

[0025] (3) The present invention utilizes the barrier ball and the scraper to cooperate with each other, and the grinding mechanism can grind and trim the slice surface in real time during the slicing process, eliminating burrs, bumps or other surface defects that may be introduced during the slicing process, thereby improving the quality and smoothness of the slice. Moreover, the cutting depth and position of the laser slicer can be adjusted in real time through the grinding mechanism to maintain the accuracy and consistency of the slice, avoiding uneven slices or inaccurate sizes due to errors in the cutting process. At the same time, the grinding mechanism can be carried out simultaneously with the slicing process without the need for additional processes or operations, saving time and labor costs and improving work efficiency. Furthermore, the grinding mechanism can instantly trim the slice surface during the slicing process, reducing subsequent secondary processing processes and improving production efficiency and product quality. At the same time, regular grinding can remove the accumulation and dirt on the surface of the laser head, ensuring that the laser head remains clean, thereby improving the cutting quality and accuracy. Frequent grinding of the laser head can reduce burning and fragmentation during the cutting process, thereby improving the cutting quality and reducing the scrap rate. Finally, regular grinding of the laser head can reduce the replacement frequency, reduce maintenance costs and extend the service life of the equipment.

[0026] (4) The present invention utilizes the telescopic sleeve and the suction cup to cooperate with each other, and the slices are automatically sucked out by the discharging mechanism, which reduces manual operation and improves production efficiency and consistency. The method of using the discharging mechanism to suck out the battery slices can reduce the risk of damage caused by manual operation and ensure product integrity. In addition, the link of manual contact with the battery slices is reduced, reducing the risk of worker injury. At the same time, the discharging mechanism can accurately locate and extract the battery slices, ensuring the quality and specification consistency of the product, and the discharging mechanism can reduce labor costs and reduce scrap rates, thereby reducing production costs. Finally, the discharging mechanism can speed up the production rhythm, improve production efficiency, and shorten the production cycle. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The following are the complete usage steps and working principles of the above embodiment:

[0056] The device is mainly used for: Figure 1As shown, first, it is necessary to prepare the raw materials of solar cells - silicon single crystal or multi-crystalline silicon wafers. These wafers usually have a certain diameter and length and are the basic materials for preparing solar cells. Then the wafers are cut by a laser slicer 1. Secondly, the motion controller 11 drives the laser head 14 to cut the cell into thin slices. In addition, the motion controller 11 slides inside the slide rail 13, which can cut the cell in multiple directions. The purpose of cutting is to cut the silicon rod into thin slices that meet the size requirements of the solar cell, usually with a thickness of tens to hundreds of microns.

[0057] Multi-range scratching mechanism 2 for removing impurities, dust and residues on the surface of the battery cell. When used:

[0058] like Figures 3 to 5 As shown, the operator first places the battery cell to be cut on the upper surface of the workbench 22. Then, since the outer wall of the laser head 14 is fixedly connected to the annular gear 21, the motion controller 11 will drive the annular gear 21 to move when driving the laser head 14 to move inside the slide rail 13 to cut the surface of the battery cell. Furthermore, since the upper surface of the workbench 22 is also fixedly connected to the fixed plate 23, and the outer wall of the fixed plate 23 is also provided with a plurality of protrusions, and the cylindrical gear 24 is rotatably connected to the upper surface of the top protrusion, when the motion controller 11 drives the laser head 14 to move horizontally to cut the battery cell to the position where the annular gear 21 and the cylindrical gear 24 are meshed with each other, the annular gear 21 and the cylindrical gear 24 form a meshing transmission, and then the motion controller 11 drives the annular gear 21 to move horizontally, which will simultaneously drive the cylindrical gear 24 to rotate. Therefore, the first long connecting rod 25 eccentrically fixedly connected to the lower end of the cylindrical gear 24 will deflect and rotate synchronously with the rotation of the cylindrical gear 24. In addition, the lower end of the first long connecting rod 25 is also eccentrically fixedly connected to the second long connecting rod 26. Therefore, the deflection and rotation of the first long connecting rod 25 will drive the deflection and rotation of the second long connecting rod 26, and the deflection direction of the first long connecting rod 25 is opposite to the deflection direction of the second long connecting rod 26. In addition, the end of the second long connecting rod 26 away from the first long connecting rod 25 is also rotatably connected to the transfer rod 27, and the end of the transfer rod 27 away from the second long connecting rod 26 is fixedly connected to the brush plate 28. Then, through the alternating deflection and rotation of the second long connecting rod 26 and the transfer rod 27, the transfer rod 27 drives the brush plate 28 to make a circular motion on the surface of the workbench 22, so that the transfer rod 27 drives the brush plate 28 to wipe the surface of the workbench 22.

[0059] Summary 1: Compared with the prior art, there may be burrs on the surface of the battery cell after cutting. The present mechanism realizes that the alternating deflection and rotation of the second long connecting rod 26 and the adapter rod 27 will cause the adapter rod 27 to drive the brush plate 28 to make a circular motion on the surface of the workbench 22. In this way, the circular motion of the brush plate 28 driven by the adapter rod 27 will realize wiping the surface of the workbench 22. Through the circular motion, the multi-range scratching mechanism 2 can more comprehensively contact the surface of the battery cell and effectively remove tiny silicon dust, debris and other impurities. This movement mode can cover every area of ​​the battery cell to ensure more thorough cleaning. Secondly, during the slicing process, some tiny scratches or defects may appear on the surface of the battery cell. The multi-range scratching mechanism 2 with circular motion can help reduce the impact of these defects, and by effectively removing surface impurities, reduce the defect rate of the battery cell surface and improve the final product Quality, secondly, by completing the cleaning step at the same time as slicing, the process time of subsequent separate cleaning is reduced. This integrated processing method can significantly improve the efficiency of the entire production line and shorten the production cycle. Moreover, the multi-range scratching mechanism 2 can prevent debris from slicing and accumulating on the equipment, which helps to reduce equipment wear and maintenance requirements and extend the service life of the equipment. Moreover, if the silicon dust generated during the slicing process is not cleaned in time, it will not only affect the performance of the battery cell, but also pollute the workshop environment. The circular motion multi-range scratching mechanism 2 can effectively control dust, keep the working environment clean, and reduce harm to personnel and the environment. Finally, by performing real-time cleaning during the slicing process, it can be ensured that each battery cell undergoes the same treatment to ensure product consistency and reliability, which is especially important for mass production of high-quality solar cells.

[0060] The knocking mechanism 3 is used to release the internal stress of the battery cell and reduce the risk of breakage during subsequent processing or use. When the mechanism is used:

[0061] like Figures 6 and 7 As shown, when the first long link 25 deflects and rotates, the ratchet gear 34 rotatably connected to the upper surface of the first long link 25 will rotate synchronously. Furthermore, the outer wall of the ratchet gear 34 is clamped with the obstacle buckle 33, so the rotation of the ratchet gear 34 will synchronously drive the obstacle buckle 33 to swing back and forth. Furthermore, the obstacle buckle 33 is fixedly connected to the outer wall of the fixing rod 32, and the fixing rod 32 is rotatably connected to the top of the connecting block 31, so the back and forth reciprocating swing of the obstacle buckle 33 will drive the fixing rod 32 to rotate. Furthermore, a hammer ball 35 is also fixedly connected to the outer wall of one side of the obstacle buckle 33. In this way, when the obstacle buckle 33 swings back and forth, it will synchronously drive the hammer ball 35 to deflect back and forth, so that the adhesion of the battery cell on the surface of the workbench 22 after the cutting is completed can be hammered to release the internal stress generated when the battery cell is cut.

[0062] Summary 2: Compared with the existing technology, the battery cell may accumulate internal stress after the cutting is completed. The present mechanism realizes that when the barrier buckle 33 swings back and forth, it will synchronously drive the hammer ball 35 to deflect back and forth. The knocking mechanism 3 can produce tiny deformations or indentations on the surface of the battery cell, which may help to improve the adhesion and uniformity of subsequent processes such as metallization and electrode printing. Secondly, the knocking mechanism 3 can, in some cases, enhance the overall mechanical strength of the material by introducing microstructural changes, increase the durability and life of the battery cell, and at the same time, the knocking mechanism 3 may help to change the physical and chemical properties of the battery cell surface, making it more active, thereby improving the effects of subsequent process steps such as coating and plating. Furthermore, the knocking mechanism 3 can help expose and remove tiny defects on the surface of the battery cell, such as cracks or holes, which helps to improve The quality and performance of the final product can be improved. At the same time, during the slicing process, the battery cells may adhere due to static electricity or other reasons. The knocking mechanism 3 can help separate these adhered battery cells to ensure that they can be smoothly transported and processed. Furthermore, the knocking mechanism 3 can shake off debris and dust on the surface and edge of the battery cells to keep the battery cells clean, which is very important for quality control of subsequent processes because debris and dust may affect the performance of the battery cells. In addition, during the slicing process, the battery cells may warp due to internal stress. The knocking mechanism 3 can help release this stress and keep the battery cells flat, which helps to improve the accuracy of subsequent processing and assembly. Finally, the knocking mechanism 3 can help eliminate or reduce the accumulation of static electricity on the surface of the battery cells, further reducing the risk of battery cell adhesion and reducing quality problems caused by static electricity.

[0063] The grinding mechanism 4 for removing the accumulation and dirt on the surface of the laser head 14 is specifically used as follows:

[0064] like Figures 8 and 9As shown, when the motion controller 11 moves to the wedge-shaped fastener 414 on the slide rail 13, the motion controller 11 pushes the wedge-shaped fastener 414 to move to the right inside the slide chute body 413. In addition, the initial position of the wedge-shaped fastener 414 near the concave point at one end of the electric telescopic rod 416 conflicts with the outer wall of the top end of the electric telescopic rod 416. Then, as the wedge-shaped fastener 414 moves to the convex point at one end, the wedge-shaped fastener 414 will squeeze the electric telescopic rod 416 downward, so that the electric telescopic rod 416 moves downward and extends, thereby touching the relay switch 46. In addition, one end of the relay switch 46 is connected to the output end of the reduction motor shaft installed inside the housing 43, so the relay switch 46 will drive the reduction motor to start, so the reduction motor will drive the housing 43 to rotate. At the same time, the top and bottom ends of the housing 43 are fixedly connected to the turntable 42 and the fixed plate 44 respectively, so the rotation of the fixed plate 44 will synchronously drive the turntable 42 and The fixed disk 44 rotates, and the outer wall of the fixed disk 44 is also fixedly connected to the teeth 45. The rotation of the fixed disk 44 will drive the teeth 45 to rotate, and then the outer gear 47 meshing with the teeth 45 fixedly connected to the outer wall of the fixed disk 44 will rotate with the rotation of the teeth 45. In addition, the outer gear 47 is rotatably connected to the side of the turntable 42 close to the turntable 42. The initial position of the obstacle ball 48 contacts the end point of the raised portion of the turntable 42. Therefore, as the turntable 42 rotates, the raised portion pushes the obstacle ball 48 to deflect, and then the obstacle ball 48 moves away from the connecting shaft 49 fixedly connected to one end of the external gear 47, and the scraper 410 fixedly connected to one end of the connecting shaft 49 will flip over with the deflection of the obstacle ball 48. At the same time, the initial position of the scraper 410 is on the inclined surface and is on the same horizontal plane as the laser head 14, and then the flipping of the scraper 410 will scrape the surface of the laser head 14.

[0065] Summary 3: Compared with the existing technology, frequent use will cause the laser head 14 to wear. This mechanism realizes that the obstacle ball 48 is away from the connecting shaft 49 fixedly connected at one end of the external gear 47, and the scraper 410 fixedly connected at one end of the connecting shaft 49 will flip with the deflection of the obstacle ball 48. At the same time, the initial position of the scraper 410 is on the inclined surface and is on the same horizontal plane as the laser head 14. Then, the flipping of the scraper 410 will scrape the surface of the laser head 14. The grinding mechanism 4 can grind and trim the slice surface in real time during the slicing process, eliminate burrs, bumps or other surface defects that may be introduced during the slicing process, thereby improving the quality and smoothness of the slices. Moreover, through the grinding mechanism 4, the cutting depth and position of the laser slicer 1 can be adjusted in real time to maintain the accuracy and consistency of the slices, avoiding Avoid uneven slices or inaccurate sizes due to errors in the cutting process. At the same time, the grinding mechanism 4 can be carried out simultaneously with the slicing process without the need for additional processes or operations, saving time and labor costs and improving work efficiency. Moreover, the grinding mechanism 4 can instantly trim the slice surface during the slicing process, reducing subsequent secondary processing processes, improving production efficiency and product quality. At the same time, regular grinding can remove the accumulation and dirt on the surface of the laser head 14, ensuring that the laser head 14 remains clean, thereby improving cutting quality and accuracy. Frequent grinding of the laser head 14 can reduce burning and fragmentation during the cutting process, thereby improving cutting quality and reducing scrap rate. Finally, regular grinding of the laser head 14 can reduce replacement frequency, reduce maintenance costs, and extend the service life of the equipment.

[0066] Automatically remove the cut battery cells, which can greatly reduce the manual intervention of the discharge mechanism 5. When the mechanism is used specifically:

[0067] like Figure 10As shown, when the cell cutting on the surface of the workbench 22 is completed, the operator can pull the telescopic sleeve 53 to move downward at the axis of the outer wall of the protective shell 57 until the suction cup 56 is in contact with the surface of the cell, and then the operator moves outward to pull the push rod 52. In addition, since the toothed wheel 54 and the rack shaft 51 are engaged with each other, when the push rod 52 pulls the rack shaft 51 to move outward, the toothed wheel 54 will rotate clockwise. Furthermore, the telescopic sleeve 53 passes through and is fixedly connected to the inside of the toothed wheel 54, and the clockwise rotation of the toothed wheel 54 will synchronously drive the telescopic sleeve 53 to rotate. In addition, the outer wall of the bottom end of the telescopic sleeve 53 is fixedly connected to the rotating rod 55, and the end of the rotating rod 55 away from the telescopic sleeve 53 is fixedly connected to the rotating rod 55. Suction cup 56, the clockwise rotation of the telescopic sleeve 53 will synchronously drive the rotating rod 55 and the suction cup 56 to deflect clockwise. Since the suction cup 56 is made of rubber, the rubber material has good elasticity and wear resistance, and is suitable for bearing heavier workpieces. The rubber material also has good oil resistance, acid and alkali resistance and other properties, which can meet the needs of various processing environments. Since the power source of the suction cup 56 is pneumatic, turn on the air source and generate negative pressure on the suction cup 56 through the pneumatic control system to form an adsorption force, thereby ensuring that the suction cup 56 is closely attached to the surface of the battery cell and ensuring that the adsorption force is strong enough to prevent the lens from falling off. Then, the suction cup 56 attached to the surface of the battery cell sucks the battery cell and then leaves the workbench 22, making it convenient for the staff to take it out.

[0068] Summary 4: Compared with the prior art in which manual hands are put into the workbench 22 to pick up the battery cells, this mechanism realizes that the clockwise rotation of the telescopic sleeve 53 will synchronously drive the rotating rod 55 and the suction cup 56 to deflect clockwise, and the slices are automatically sucked out by the discharging mechanism 5, which reduces manual operation and improves production efficiency and consistency. The method of sucking out the battery cells by the discharging mechanism 5 can reduce the risk of damage caused by manual operation and ensure product integrity. In addition, it reduces the link of manual contact with the battery cells and reduces the risk of worker injury. At the same time, the discharging mechanism 5 can accurately locate and extract the battery cells to ensure the quality and specification consistency of the product, and the discharging mechanism 5 can reduce labor costs and reduce scrap rates, thereby reducing production costs. Finally, the discharging mechanism 5 can speed up the production rhythm, improve production efficiency, and shorten the production cycle.
