[0001] This utility model relates to the field of laser equipment technology, and in particular to a laser grooving device and a laser processing equipment. Background Technology

[0002] Back-contact batteries (BC batteries) are an advanced, high-efficiency solar cell technology. Their core structural feature lies in placing the traditional PN junction and the metal electrode contacts for current collection on the back of the cell, while the front of the cell is completely covered with an anti-reflective passivation film. This unique design effectively eliminates light obstruction by the front electrodes, significantly improving the cell's light absorption and photoelectric conversion efficiency, making it a leading representative in the field of high-efficiency photovoltaic cells.

[0003] To precisely form trenches or channels for electrode connections on the back side of BC solar cells, laser grooving equipment is commonly used in the prior art. These devices utilize high-energy-density laser beams to locally remove or modify specific areas on the back side of the solar cell according to preset paths and parameters, thereby exposing the PN junction and facilitating subsequent deposition or connection of metal electrodes.

[0004] However, the automation level of existing laser grooving equipment is generally low, which not only leads to low production efficiency but also increases the instability of quality between batches. Utility Model Content

[0008] In one embodiment, the transfer module includes: A fixing base is provided on the mounting surface; The second turntable is rotatable about its own axis and is mounted on the fixed base. A second rotary drive component, which is connected to the second turntable in a transmission manner, is used to drive the second turntable to rotate; and A gripping unit, located on the second turntable, is used to grip or release the battery cell.

[0009] In one embodiment, the gripping part protrudes from the peripheral side of the second turntable and is integrally formed with the second turntable. The gripping part includes an arm and a gripping structure. The arm is movably disposed above the mounting surface, and the gripping structure is disposed on the side of the arm close to the mounting surface.

[0012] In one embodiment, the laser grooving device further includes a conveying module, which includes a conveying track and a shaping mechanism. The conveying track has a first end and a second end disposed opposite to each other. The first end of the conveying track is disposed close to the rotary processing module, and the second end of the conveying track is disposed away from the rotary processing module. The shaping mechanism is disposed close to the first end of the conveying track and is used to shape the battery cell located on the conveying track. The discharge station or the infeed station is formed at the first end of the conveying track. The conveying module is used to transport the battery cell located at the discharge station from the first end of the conveying track to the second end of the conveying track for unloading; or, the conveying module is used to transport the battery cell located at the second end of the conveying track to the infeed station located at the first end of the conveying track for loading.

[0013] In one embodiment, the laser grooving device includes two conveying modules, and the two conveying tracks of the two conveying modules respectively form an infeed track and an outfeed track.

Specifically, the device is equipped with a base and multiple stations such as feeding, discharging, transfer, cleaning, photographing, and grooving. The rotary processing module includes a first rotary drive and a first turntable with multiple processing positions. The arrangement of multiple processing positions around the axis can simultaneously place and process multiple battery cells. During grooving, the battery cells are first transferred from the feeding station to the processing position located at the transfer station by the transfer module. Then, driven by the first rotary drive, the entire first turntable rotates, causing the battery cells at the processing position to sequentially and accurately reach the cleaning station (for surface treatment), the photographing station (for positioning and quality inspection), and the grooving station (for precise grooving). Finally, they pass through the transfer station again and are then sent to the discharging station by the transfer module. Driven by the first turntable, the battery cells located at each processing position sequentially reach the discharging station. Thus, through the multi-station parallel processing capability of the rotary processing module and the rapid transfer capability of the transfer module, while the equipment is processing one solar cell, other solar cells can be prepared or undergo subsequent processes at different stations, which greatly shortens the total processing cycle of a single solar cell and achieves continuous and efficient production. Moreover, the entire process, from feeding, transfer, cleaning, and photographing to grooving and unloading, is completed automatically by the machine, reducing human intervention and avoiding errors and delays caused by human operation. In addition, the standardized automatic process ensures that each solar cell undergoes the same processing steps and parameters, reducing quality fluctuations caused by operational differences between batches, thereby improving the yield and consistency of the final product.

[0024] This application provides a laser grooving device 100.

[0025] Please see Figure 1 and Figure 2In one embodiment of this utility model, the laser grooving device 100 includes: The machine base 1 has a mounting surface 11 formed on it. The mounting surface 11 has a feeding station 12, a discharging station 13, a transfer station 14, a cleaning station 15, a photographing station 16, and a grooving station 17. A rotary processing module 2 includes a first rotary drive 22 disposed on a mounting surface 11 and a first turntable 21 pulsator connected to the first rotary drive 22. The first turntable 21 has multiple processing positions arranged sequentially around the axis of the first turntable 21, each processing position being used to place a battery cell. The first rotary drive 22 is used to drive the first turntable 21 to rotate around the axis of the first turntable 21. The transfer module 3 is located on the mounting surface 11. The transfer module 3 is used to transfer the battery cells located at the feeding station 12 to the processing station located at the transfer station 14 for processing. The transfer module 3 is also used to transfer the battery cells located at the processing station on the transfer station 14 to the unloading station 13 for unloading. Among them, the battery cells located at the processing position are driven by the first turntable 21 to the transfer station 14, the cleaning station, the photography station, the grooving station and the transfer station 14 in sequence.

[0026] It should be noted that the transfer module 3 has diverse applications in industrial production. Its design typically combines automation and precise positioning technologies to achieve efficient and safe material transfer. For example, the transfer module 3 can be a robotic arm or a vacuum adsorption unit, which can not only accurately grasp or pick up battery cells but also prevent them from being damaged during transfer. In addition, the transfer module 3 may also include an AGV (Automated Guided Vehicle) cart and a matching pallet, which uses sensing positioning and lifting devices to achieve rapid and automated transfer of battery modules, thereby improving production efficiency and reducing manual intervention.

[0027] In this embodiment, the laser grooving device 100, by adopting an integrated multi-station rotary platform combined with an automatic transfer system, can solve the problems of low automation, low production efficiency and unstable quality between batches in existing laser grooving equipment. Specifically, the device is equipped with a base 1 and multiple workstations such as feeding, discharging, transfer, cleaning, photographing, and grooving. The rotary processing module 2 includes a first rotary drive 22 and a first turntable 21 with multiple processing positions. The arrangement of the multiple processing positions around the axis can simultaneously place and process multiple battery cells. When grooving, the battery cells are first transferred from the feeding station 12 to the processing position located at the transfer station 14 by the transfer module 3. Then, driven by the first rotary drive 22, the entire first turntable 21 rotates so that the battery cells at the processing position arrive at the cleaning station 15 (for surface treatment), the photographing station 16 (for positioning and quality inspection), and the grooving station (for precise grooving) in sequence. Finally, they pass through the transfer station 14 again and are sent to the discharging station 13 by the transfer module 3. Driven by the first turntable 21, the battery cells located at each processing position arrive at the discharging station 13 in sequence. Thus, through the multi-station parallel processing capability of the rotary processing module 2 and the rapid transfer capability of the transfer module 3, while the equipment is processing one solar cell, other solar cells can be prepared or undergo subsequent processes at different stations, greatly shortening the total processing cycle of a single solar cell and achieving continuous and efficient production. Moreover, the entire process, from feeding, transfer, cleaning, and photographing to grooving and unloading, is completed automatically by the machine, reducing human intervention and avoiding errors and delays caused by human operation. In addition, the standardized automatic process ensures that each solar cell undergoes the same processing steps and parameters, reducing quality fluctuations caused by operational differences between batches, thereby improving the yield and consistency of the final product.

[0028] In one embodiment, the laser grooving device 100 may selectively employ one or more of the following: an electrostatic ion wind cleaning station, a high-precision laser generating module, or a high-resolution visual recognition module.

[0029] In this embodiment, when the electrostatic ion wind cleaning station is used, when the battery cell rotates to the cleaning station 15 with the first turntable 21, the electrostatic ion wind blown out by the electrostatic ion wind cleaning station can not only blow away loose dust particles, but also neutralize the electrostatic charge adsorbed on the surface, remove the tiny particles and electrostatic adsorbed impurities on the surface of the battery cell, thereby more thoroughly removing contaminants that may affect subsequent grooving and electrode connection. This ensures that the battery cell has a clean surface before entering the photography and grooving station 17.

[0030] When a high-resolution vision recognition module is used, it can capture a clear image of the back of the solar cell located at the processing position and transmit the data to the control system in real time. Through image processing algorithms, it can accurately identify the features of the solar cell, such as determining the location of the hidden grid structure, grooving parameters (such as groove depth, groove width, and spacing), and preset marks. This provides an extremely accurate positioning reference for subsequent laser grooving, ensuring that the grooving position perfectly matches the design. Of course, this high-resolution vision recognition module can also be used to detect defects in the solar cell in real time.

[0031] When a high-precision laser generator module is used, it provides a stable, energy-concentrated, and wavelength-accurate laser beam. Combined with a dynamic focusing system, the laser beam can precisely and with extremely high resolution groove the back of the solar cell, ensuring that the laser beam is always in the optimal focusing state to achieve tiny and clearly defined grooves. This ensures that the grooves are precisely aligned with the hidden grid structure, and that the groove shape meets the high-efficiency conductivity requirements of XBC solar cells. Furthermore, the dynamic focusing system can reduce the refocusing time caused by changes in the workpiece surface shape. Combined with the high-precision laser generator, this significantly improves processing efficiency.

[0032] Of course, when two or three of the following are used simultaneously: electrostatic ion wind cleaning station, high-precision laser generation module or high-resolution visual recognition module, their synergistic effect can minimize defects caused by various factors and significantly improve the yield and consistency of the final product, especially for high-end products such as back contact batteries that have extremely high requirements for surface cleanliness and processing precision.

[0033] Please see Figure 1 In one embodiment, the feeding station 12, the discharging station 13 and the transfer station 14 are located on the first side, the second side and the third side of the transfer module 3, respectively, with the first side and the second side being arranged opposite to each other; the third side is arranged close to both the first side and the second side.

[0034] In this embodiment, the feeding station 12, discharging station 13, transfer station 14, and transfer module 3 form a "T"-shaped layout, creating a relatively compact material flow path. Specifically, since the feeding, discharging, and main transfer operations are concentrated on three relatively close sides, the material avoids large-scale, long-distance movement around the equipment, making the entire device more compact and saving valuable production workshop space. This shortens the total distance the battery product needs to travel from feeding to discharging, especially reducing the movement range and stroke of the transfer module 3, thereby accelerating the material flow speed and helping to improve the overall production cycle and efficiency. In addition, placing the feeding and discharging ports on opposite sides is more in line with the habits of production line layout, facilitates docking with other equipment, and also makes the movement planning of the transfer module 3 relatively simple, making it easier for maintenance and operators to observe.

[0035] Please see Figure 3 In one embodiment, the transfer module 3 includes: Fixing base 31, the fixing base 31 is provided on the mounting surface 11; The second turntable 32 is rotatable around its own axis and is mounted on the fixed base 31. The second rotary drive component is connected to the second turntable 32 for driving the second turntable 32 to rotate; and The gripping unit 33 is located on the second turntable 32 and is used to grip or release the battery cells.

[0036] In this application, the fixed base 31 is located on the mounting surface 11, providing stable support for the entire device and ensuring the rigidity of the equipment during operation. The second turntable 32 can rotate around its own axis and achieves precise rotation through the second rotary drive component, thereby quickly and accurately adjusting the position of the solar cells during transfer. The gripping part 33 is located on the second turntable 32, which can efficiently grip or release the solar cells, avoiding collisions or damage during transfer. This design enables the solar cells to be quickly and stably transferred from the previous process to the next process in the laser grooving process, while reducing positioning errors and improving the accuracy and efficiency of grooving. Therefore, this device not only improves production efficiency but also enhances the stability of the process and the consistency of solar cell processing, providing a reliable guarantee for high-precision laser grooving technology.

[0037] In one embodiment, the gripping part 33 protrudes from the peripheral side of the second turntable 32 and is integrally formed with the second turntable 32. The gripping part 33 includes an arm body 331 and a gripping structure. The arm body 331 is movably disposed above the mounting surface 11, and the gripping structure is disposed on the side of the arm body 331 close to the mounting surface 11. The gripping structure is used to clamp or pick up battery cells.

[0038] In this embodiment, since the gripping part 33 and the second turntable 32 are integrally formed, the overall rigidity and coaxiality of the structure can be improved, avoiding the small gaps and deformations that may be introduced by traditional splicing or connection methods. This ensures that when the second turntable 32 rotates at high speed or precision, the battery cells can be stably transferred to the target station with extremely high repeatability. This integrated precision allows the positional deviation of the battery cells during the transfer process to be controlled within a very small range. In addition, the gripping structure adopts a clamping or suction method, which can achieve precise and gentle gripping of the edges or specific areas of the battery cells, minimizing the mechanical stress on the surface and edges of the battery cells and avoiding precision loss or damage caused by uneven gripping force or collision.

[0039] Please continue reading. Figure 3In one embodiment, the transfer module 3 includes two gripping parts 33, the extension directions of the arms 331 of the two gripping parts 33 are set at an angle so that the two gripping parts 33 can simultaneously grip or release two battery cells located in adjacent positions in the feeding station 12, the discharging station 13 and the transfer station 14.

[0040] In this embodiment, the arm 331 of each gripping unit 33 is positioned according to its angle, and the gripping structure on it can be aligned with and grip or release two adjacent battery cells. Thus, during the battery cell transfer process, for example at the infeed station 12, the outfeed station 13, or a specific transfer station 14, when two battery cells are placed adjacent to each other, the two angled gripping units 33 can simultaneously and independently approach their respective target battery cells. When the second turntable 32 rotates, the two gripping units 33 work together as a whole to quickly transfer the two simultaneously gripped battery cells to the designated station, or release the two battery cells from the designated station simultaneously. This design allows steps that originally required two separate operations to be combined into one synchronous operation, which can significantly improve the transfer efficiency of battery cells, shorten the processing time of a single cell, and increase the production cycle of the entire laser grooving device 100. At the same time, this parallel processing method also optimizes the utilization rate of the station layout, reduces the time spent by the equipment idling or waiting, thereby improving the overall throughput and equipment utilization rate of the production line.

[0041] Please see Figure 4 In one embodiment, the mounting surface 11 also has an emergency station 18, which is located on the fourth side of the transfer module 3. The fourth side is located close to both the first and second sides and is opposite to the third side.

[0042] In this embodiment, the emergency station 18, the feeding station 12, the discharging station 13, the transfer station 14, and the transfer module 3 form a cross-shaped layout, further creating a relatively compact material flow path. In this cross-shaped layout, the transfer module 3 (such as the second turntable 32) is roughly located in the center. This layout makes the path of the battery cells from feeding, switching between stations via the transfer module 3, to discharging, and finally entering the emergency station 18 in an emergency relatively concentrated and short. The rotation of the transfer module 3 can directly serve each station, reducing the long-distance movement of the battery cells. In addition, when a quality problem requiring urgent handling is detected in a battery cell, the battery cell can be placed in the emergency station 18 manually or by other transfer mechanisms. The transfer module 3 can quickly guide it from the feeding, discharging, or transfer process to the emergency station 18 located on the fourth side. At the emergency station 18, the transfer module 3 can quickly transfer and process it or send it to other processes without significantly interrupting the normal battery cell flow on the main line. This improves the production line's response speed and handling efficiency to abnormal situations, effectively isolates defective products, and prevents them from flowing into the next process and causing greater losses or affecting product quality consistency. At the same time, this layout also allows operators to quickly reach emergency station 18 for intervention, reducing production downtime and improving the overall stability and yield rate of the production line.

[0043] Please see Figure 4 In one embodiment, the laser grooving device 100 further includes a conveying module, which includes a conveying track and a shaping mechanism. The conveying track has a first end and a second end that are disposed opposite to each other. The first end of the conveying track is disposed close to the rotary processing module 2, and the second end of the conveying track is disposed away from the rotary processing module 2. The shaping mechanism is disposed close to the first end of the conveying track and is used to shape the battery cells located on the conveying track. A discharge station 13 or a loading station 12 is formed at the first end of the conveying track. The conveying module is used to transport the battery cells located at the discharge station 13 from the first end of the conveying track to the second end of the conveying track for unloading; or, the conveying module is used to transport the battery cells located at the second end of the conveying track to the loading station 12 located at the first end of the conveying track for loading.

[0044] It should be noted that the shaping mechanism for solar cells is typically an automated device that includes mechanisms for conveying, straightening, and positioning. Its core function is to precisely position and neatly arrange the solar cells before they enter subsequent critical processes (such as laser grooving). This is usually achieved through a vibration platform to automatically align the cells, or by using mechanical clamps, guide blocks, or other structures to force alignment. This effectively solves the problems of displacement, tilting, or stacking that may occur during transportation or storage, ensuring that each solar cell is in the correct position and orientation. This significantly improves the processing accuracy of subsequent processes such as laser grooving, reduces the defect rate, and enhances the overall efficiency and stability of the production line.

[0045] In addition, conveyor tracks typically include a base, guiding structures (such as channels, roller guides, or chain tracks), a material-carrying plane or bracket (such as rollers, belts, chains, or plates), and a drive mechanism that moves the material-carrying plane. Conveyor tracks can take many forms, such as roller conveyors that rely on rotating rollers to propel materials forward, belt conveyors that rely on continuous belts to carry and transport materials, or chain or plate chain conveyors used for high-precision positioning or complex paths.

[0046] In this embodiment, before or after the solar cell needs to be grooved, the transfer module 3 places it at the first end (feeding station 12) or the second end of the conveying track. The conveying module is activated, and the solar cell moves along the conveying track. The shaping mechanism shapes the solar cell to ensure its flatness and orientation are consistent when it enters the feeding station 12 or the next process, which can improve processing quality and the stability of subsequent processes. The cooperation between the conveying module and the transfer module 3 forms a continuous and automated material conveying chain, reducing manual intervention and improving the efficiency of loading and unloading. This design allows the solar cell to enter and exit the laser grooving device 100 smoothly and orderly, which not only improves production efficiency but also ensures the positioning accuracy and consistency of the solar cell throughout the process, thereby improving the yield and performance of the final product.

[0047] In one embodiment, the laser grooving device 100 includes two conveying modules, and the two conveying tracks of the two conveying modules respectively form an infeed track 4 and an outfeed track 5. The infeed station 12 and the outfeed station 13 are respectively formed at the first end of the infeed track 4 and the first end of the outfeed track 5.

[0048] In this embodiment, by employing two independent conveying modules to form the infeed track 4 and the outfeed track 5 respectively, and setting the infeed station 12 and the outfeed station 13 at the first end of their respective tracks, the problems of process conflicts, efficiency bottlenecks, and material confusion that may occur when handling loading and unloading in a single conveying channel can be solved. Specifically, in the grooving process, the battery cells to be processed are picked up by the transfer module 3 via the infeed conveying module, passing through the first end of the infeed track 4 (i.e., the infeed station 12), and sent to the grooving station 17 for processing. The grooved battery cells are then placed by the transfer module 3 onto the outfeed conveying module, and transported along the outfeed track 5 via the first end of the outfeed track 5 (i.e., the outfeed station 13), finally completing the unloading. The two conveying modules operate independently without interference, realizing parallel processing of the loading and unloading processes, avoiding time conflicts between loading and unloading on the same channel, and significantly improving the efficiency of material flow and the overall production cycle. Meanwhile, the physical separation effectively prevents the mixing of unprocessed and processed solar cells during transport, ensuring clarity of the production process and accuracy of material management. This layout enables the laser grooving device 100 to operate more efficiently and reliably, improving the overall capacity of the production line and the safety of material handling.

[0049] This utility model also provides a laser processing device, including a laser grooving device 100.

Since this laser processing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.
