Description

Technical Field

[0001] This utility model belongs to the field of laser slicing, and specifically discloses a solar cell laser slicing device. Background Technology

[0002] Laser slicing is a process that uses a high-energy laser beam to precisely cut silicon wafers. The laser beam, through a focusing lens, concentrates energy into a tiny area on the surface of the silicon wafer, causing that area to rapidly melt, vaporize, or reach its ignition point, thus achieving the cutting of the silicon wafer. This method is characterized by high precision, high efficiency, and high flexibility.

[0003] Solar cells are hard and brittle, and traditional mechanical cutting can easily lead to wafer breakage or surface damage. Lasers, by precisely controlling the heat-affected zone, avoid mechanical stress damage, making them particularly suitable for processing hard or brittle materials.

[0004] Against the backdrop of the rapid development of the photovoltaic industry, the slicing precision and production efficiency of solar cells directly affect the power generation performance and manufacturing cost of photovoltaic modules.

[0019] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-8The solar cell laser slicing device shown includes a base plate 1, a rotating disk 4, and six material support mechanisms 6 on the surface of the rotating disk 4. A semi-circular frame 2 is fixedly installed at the front end of the base plate 1. A circular base 3 is installed on the surface of the base plate 1 and inside the semi-circular frame 2 via support legs. The rotating disk 4 is rotatably mounted above the circular base 3. A stepper motor 5 is installed below the circular base 3, and the output end of the stepper motor 5 is connected to the rotating disk 4. The six material support mechanisms 6 are evenly installed at the ends of the rotating disk 4. An operating mechanism 11 is provided above the center of the rotating disk 4. The operating mechanism 11 includes a fixed cylinder 12. Four support frames 8 are evenly installed on the inner wall of the semi-circular frame 2. The other end of the support frame 8 is fixedly connected to the bottom of the fixed cylinder 12. A straight groove 9 is formed on the surface of the support frame 8. A laser cutting component 10 is slidably installed inside the straight groove 9. A second path groove 14 and a third path groove are formed on the surface of the fixed cylinder 12. The system includes four first path slots 15 and four first path slots 13, each with a connecting rod 17 installed inside. The bottom of the connecting rod 17 corresponds to the laser cutting component 10. The second path slot 14 and the third path slot 15 are respectively equipped with a first pressing component and a second pressing component. A cylinder 7 is installed on the top of the fixed cylinder 12, and a control component is installed inside the fixed cylinder 12. The cylinder 7 can control the control component. Through the cooperation of the operating mechanism 11 and the material support mechanism 6, combined with the stepping revolution design, multiple processes such as feeding, cutting, cleaning and unloading can be carried out in parallel. When one material support mechanism is working at the cutting position, other material support mechanisms can simultaneously complete feeding, angle adjustment or unloading, which greatly shortens the processing cycle of a single solar cell. Furthermore, with the precise matching of the revolution and rotation of the material support mechanism 6, the angle adjustment error of the solar cell is ensured to be minimal each time, providing a stable angle reference for the "rice" shaped four-blade cutting.

[0022] A gear ring (37) is arranged on the end face in the inner cavity of the circular base (3); six gears (36) are evenly arranged in the inner cavity of the circular base (3), and the gears (36) mesh with the gear ring (37); the six gears (36) are respectively connected to six material holding mechanisms (6) through a central rod at the center. The gear ring (37) in the inner cavity of the circular base (3) remains stationary, the six gears (36) are evenly distributed and kept meshed with the gear ring (37), and each gear (36) is connected one-to-one with the material holding mechanism (6) on a rotating disk (4) through the central rod. When a stepping motor (5) drives the rotating disk (4) to rotate, the rotating disk (4) drives the six material holding mechanisms (6) to revolve around the center of the rotating disk (4); meanwhile, due to the meshing between the gears (36) and the fixed gear ring (37), the gears (36) roll along the gear ring (37) and rotate on their own axis during the revolution of the material holding mechanisms (6), and then drive the material holding mechanisms (6) to deflect angularly by themselves through the central rods. The stepping motor (5) drives the rotating disk (4) to rotate in a stepping mode, and the rotation angle per step is 60°. By designing the tooth ratio and meshing parameters of the gear ring (37) and the gears (36), the matching relationship between the self-rotation angle and the revolution angle of the material holding mechanisms (6) can be precisely controlled. When the rotating disk (4) rotates by 60°, the material holding mechanisms (6) rotate 45° on their own axis, so as to realize precise angle adjustment of solar cells. Each time the rotating disk (4) rotates 60°, the material holding mechanism (6) carrying a cell reaches the working position of the next laser cutting assembly (10), and at this time, the material holding mechanism (6) has rotated 45° on its own axis, so the angle of the cell is adjusted accordingly. The four laser cutting assemblies (10) respectively correspond to four self-rotations of the material holding mechanisms (6), and sequentially cut the solar cells at different angles, finally forming a "meter-shaped" (cross-shaped with diagonal lines) cutting track.

[0023] The material holding mechanism (6) comprises a rectangular block (30), a rectangular frame (33) is movably mounted on the outer surface of the rectangular block (30), and a protective cover (34) is arranged on the upper surface of the rectangular frame (33). Limiting grooves (31) are formed on four end faces of the rectangular block (30), limiting springs (32) are arranged inside the limiting grooves (31), limiting blocks are respectively mounted on four end faces, close to the rectangular block (30), of the rectangular frame (33), the limiting blocks are slidably mounted in the limiting grooves (31), and the top ends of the limiting springs (32) are fixedly connected with the limiting blocks. A cutting groove (35) is formed on the surface of the protective cover (34), a solar cell is placed on the upper surface of the rectangular block (30), the horizontal height of the protective cover (34) is higher than that of the solar cell, and the protective cover (34) surrounds the edge of the cell, which plays a role of preliminary positioning and prevents the cell from shifting during the movement or rotation of the material holding mechanism (6). The rectangular frame (33) is slidably connected with the limiting grooves (31) of the rectangular block (30) through the limiting blocks on the four end faces, and the top end of the limiting spring (32) in the limiting groove (31) is connected with the limiting block. When an external component applies pressure to the rectangular frame (33), the rectangular frame (33) compresses the limiting springs (32) and slides downward along the limiting grooves (31), the protective cover (34) descends synchronously, and the horizontal height of the protective cover (34) gradually becomes lower than that of the solar cell, which can vacate space when operating the solar cell. The cutting groove (35) formed on the surface of the protective cover (34) corresponds to the cutting path of the laser cutting assembly (10), and a laser beam can directly act on the surface of the cell through the cutting groove (35), which prevents the protective cover (34) from blocking the laser or being damaged by the laser, and ensures the smooth progress of the cutting process.

[0024] The first downward pressing component includes a first L-shaped rod 24, the top of which is slidably mounted in a second path groove 14. A right-angle block 25 is fixedly mounted on the bottom of the first L-shaped rod 24. An exhaust pipe 26 is mounted on the surface of the first L-shaped rod 24, and an air supply component 27 is provided on the surface of the fixed cylinder 12. The top of the exhaust pipe 26 is connected to the air supply component 27 via a connecting pipe. The top of the first L-shaped rod 24 is embedded in the second path groove 14 of the fixed cylinder 12. The trajectory of the second path groove 14 defines the movement path of the first L-shaped rod 24. When the first L-shaped rod 24 moves downward, the right-angle block 25 at the bottom and its... The rectangular frame 33 in the lower material support mechanism 6 is vertically aligned with the rectangular frame 33. A downward pressure is applied to the rectangular frame 33, forcing it to slide down along the limiting groove 31 of the rectangular block 30 through the limiting block. Simultaneously, the limiting spring 32 is compressed, causing the horizontal height of the protective cover 34 to gradually decrease below that of the solar cell. Subsequently, when the gas supply component 27 supplies gas to the exhaust pipe 26 through the connecting pipe, the airflow is ejected from the end of the exhaust pipe 26 and directly acts on the surface of the solar cell after cutting. This blows away impurities such as silicon slag and dust generated during the cutting process, ensuring that the surface of the cell is clean and avoiding the impact of impurities on the quality of subsequent welding, packaging and other processes.

[0025] The second pressing component includes a second L-shaped rod 28. The top of the second L-shaped rod 28 is slidably installed in the third path groove 15. A frame block 29 is fixedly installed at the bottom of the second L-shaped rod 28. When the second L-shaped rod 28 moves downward, the frame block 29 can drive the rectangular frame 33 in the material support mechanism 6 below it to move downward, forcing the rectangular frame 33 to slide down along the limiting groove 31 of the rectangular block 30 through the limiting block, and simultaneously compressing the limiting spring 32, so that the horizontal height of the protective cover 34 gradually becomes lower than that of the solar cell.

[0026] Four first path grooves 13 correspond to four support frames 8 respectively. The bottom of the connecting rod 17 is connected to the laser cutting assembly 10 via a rotating shaft. The inner wall of the first path groove 13 is provided with a sliding groove 16. The top of the connecting rod 17 is provided with a groove 18. A light rod 19 is installed inside the groove 18, and the end of the light rod 19 passes through the connecting rod 17 and is slidably installed inside the sliding groove 16. The control assembly includes a first moving disk 21 and a second moving disk 23. The first moving disk 21 is located above the second moving disk 23. The bottom of the first moving disk 21 is provided with four connecting posts 20. The other ends of the four connecting posts 20 are respectively installed inside the four grooves 18, and the ends of the connecting posts 20 are sleeved on the surface of the light rod 19. The top ends of the first L-shaped rod 24 and the second L-shaped rod 28 are fixedly connected to the second moving disk 23. The bottom of the second moving disk 23 is provided with a spring. The middle of the bottom of the first moving disk 21 is provided with a push rod 22. The output end of the cylinder 7 is connected to... The cylinder 7 is directly connected to the top of the first moving disk 21. When the cylinder 7 extends, it pushes the first moving disk 21 downward. The first moving disk 21 is connected to the light rod 19 at the top of the connecting rod 17 through four connecting posts 20, which drives the connecting rod 17 to slide along the sliding groove 16 of the first path groove 13, thereby driving the four laser cutting components 10 to move synchronously towards the inner wall of the semi-circular frame 2. During the movement of the laser cutting components 10, the solar cells below them will be laser cut. When the cylinder 7 pushes the first moving disk 21 downward, after the first moving disk 21 moves to a certain position, the bottom of the push rod 22 below it will contact the second moving disk 23. The cylinder 7 continues to push the first moving disk 21 downward, and the second moving disk 23 will be squeezed and move downward synchronously. During the movement of the second moving disk 23, the first L-shaped rod 24 and the second L-shaped rod 28 will move downward synchronously.

[0027] A feeding platform is provided on the surface of the base plate 1 and near the end of the second pressing component. A robotic arm is provided on one side of the feeding platform. The feeding platform is located on the surface of the base plate 1 and near the end of the second pressing component, serving as a carrier for placing solar cells. The robotic arm is located on one side of the feeding platform and can realize the transportation of materials on the feeding platform and the cut solar cells under the second pressing component. Uncut solar cells are placed at one end of the feeding platform and can be transported to the material support mechanism 6 under the second pressing component by the robotic arm. After the rotating disk 4 drives it to rotate one revolution, the solar cells are cut. The cut solar cells are then taken out by the robotic arm and placed at the other end of the feeding platform. Then the next uncut solar cell is transported to the material support mechanism 6 under the second pressing component.

[0028] Working principle: First, an uncutted solar cell sheet is placed at one end of the discharge table of the bottom plate 1, the mechanical arm is activated, and the cell sheet is accurately transported to the material supporting mechanism 6 below the second pressing assembly, and the cell sheet is placed on the upper surface of the rectangular block 30 of the material supporting mechanism 6. The protective cover 34 has an initial height higher than that of the cell sheet, and surrounds the edge of the cell sheet to realize primary positioning and prevent deviation during movement. Then, the stepping motor 5 drives the rotating disk 4 to rotate 60° clockwise step by step, driving the material supporting mechanism 6 carrying the cell sheet to revolve to below the first laser cutting assembly 10. Meanwhile, the gear 36 at the bottom of the material supporting mechanism 6 rolls along the fixed gear ring 37 in the circular base 3. Due to the design of the gear ratio, when the rotating disk 4 revolves 60°, the material supporting mechanism 6 rotates 45°, and the angle of the cell sheet is adjusted to the first cutting posture synchronously. At this time, the mechanical arm is activated, and the cell sheet is transported to the material supporting mechanism 6 below the second pressing assembly again. The air cylinder 7 is activated, the output end pushes the first moving plate 21 to move downward, drives the connecting rod 17 to slide along the sliding groove 16 of the first path groove 13 through the connecting column 20, drives the four laser cutting assemblies 10 to move synchronously toward the inner wall of the semicircular frame 2. During the movement of the laser cutting assemblies 10, the laser beam acts on the cell sheet through the cutting groove 35 of the protective cover 34, completing the cutting at the first angle. Repeat the above process, after the cell sheet is moved to below the last laser cutting assembly 10, the laser cutting assembly 10 completes the 45° angle cutting. According to this logic, after four operations of the laser cutting assemblies 10, the "cross"-shaped four-cutting is finally completed. When the cut solar cell sheet is moved to below the first pressing assembly, the air cylinder 7 is activated, after the first moving plate 21 moves down to the preset position, the pushing rod 22 contacts the second moving plate 23, the air cylinder 7 continues to push, the second moving plate 23 drives the first L-shaped rod 24 to move down along the corresponding path groove, the right-angle block 25 presses the rectangular frame 33, makes it slide down along the limiting groove 31, compresses the limiting spring 32, the height of the protective cover 34 drops below the cell sheet, giving way for cutting, the gas delivery assembly 27 injects gas to the surface of the cell sheet through the exhaust pipe 26, removing silicon slag and dust generated by cutting. Finally, after the rotating disk 4 rotates one circle, the cut cell sheet returns to below the second pressing assembly along with the material supporting mechanism 6, the mechanical arm is activated, takes out the cut cell sheet from the material supporting mechanism 6, and places it on the other end of the discharge table, meanwhile, the mechanical arm takes a new uncutted cell sheet from the discharge table, puts it into the material supporting mechanism 6, the rotating disk 4 continues to rotate step by step, enters the next cutting cycle, and continuous production is realized through such reciprocation.
