[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0027] Example: A laser scribing machine for perovskite photovoltaic modules, such as Figure 1As shown, the system includes a frame 1, which is made of aluminum profile, specifically the European standard 30 series, and is made of A6063-T5 aluminum alloy. The frame 1 has a length of 2500mm and a width of 1000mm. The bottom of the frame 1 is equipped with casters for easy handling and movement of the equipment. One side of the frame 1 is equipped with a first stacking device 2 and a feeding device 3 located above the first stacking device 2. The middle of the frame 1 is equipped with a fixed marking device 4 and a conveying device 5 located below the fixed marking device 4. The other side of the frame 1 is equipped with a second stacking device 6. The first stacking device 2 is used to stack unprocessed photovoltaic modules, and the loading device 3 is used to separate the photovoltaic modules stacked in the first stacking device 2 one by one. The conveying device 5 is used to transfer photovoltaic modules between the loading device 3, the fixed scribing device 4 and the unloading device 7. The fixed scribing device 4 is used to perform laser scribing operation on the photovoltaic modules. The unloading device 7 is used to transfer the scribed photovoltaic modules from the conveying device 5 to the second stacking device 6. The second stacking device 6 is used to stack the scribed photovoltaic modules.

[0028] Specifically, the first stacking device 2 and the second stacking device 6 have the same structure, such as... Figure 2 and Figure 3As shown, each includes a base plate 8 and a track 9 mounted on a frame 1; a storage bin 10 is mounted on the track 9, and the bottom of the storage bin 10 rolls with the track 9 via rollers 11; elongated holes 12 are provided on both sides of the bottom surface of the storage bin 10; a worm gear screw lifting mechanism 13, model SWL0.5-P-1A-II-160FZ-3-P worm gear screw jack, is mounted on the base plate 8, and a first lifting plate 14 is mounted on the lifting end of the worm gear screw lifting mechanism 13, with support rods 15 mounted on both ends of the first lifting plate 14, and a stacking plate 16 is fixed to the top of the support rod 15 on the same side, the stacking plate 16 corresponding to the elongated holes 12; a push plate 17 is also fixedly mounted in the middle of the bottom surface of the storage bin 10, and the end of the push plate 17 is connected to a first cylinder 18 fixed on the frame 1. In this embodiment, the storage silo 10 is responsible for the stacked storage of several photovoltaic modules. Its opening has a sloping design, ensuring that even if the loading device 3 or unloading device 7 is not precisely aligned with the opening of the storage silo 10 when placing the photovoltaic modules, the photovoltaic modules can still slide down the sloping surface to the stacking position in the storage silo 10. The moving end of the turbine screw lifting mechanism 13 is designed with a first lifting plate 14, which, through the elongated hole 12 at the bottom of the storage silo 10, works in conjunction with the stacking plate 16 to handle the stacked photovoltaic modules in the storage silo 10. The lifting and lowering mechanisms, in conjunction with the loading device 3 and unloading device 7, complete the loading and unloading transfer operations. The bottom of the storage silo 10 is equipped with rollers 11 and a track 9 that roll in cooperation. These are connected to the first cylinder 18 via a push plate 17. Whenever the photovoltaic modules in the storage silo 10 are transferred or the storage silo 10 is full of photovoltaic modules, the turbine screw lifting mechanism 13 lowers its moving end to its lowest position, causing the stacking plate 16 to detach from the bottom of the storage silo 10. Subsequently, the storage silo 10 moves horizontally along the guide rail to a designated position under the guidance of the cylinder. Furthermore, a folding rail 65 is rotatably connected to one side of the track 9, and a flipping plate 66 is installed between the folding rails 65. When the storage silo 10 needs to be moved, the flipping plate 66 drives the folding rail 65 to rotate to the same level as the track 9, allowing the storage silo 10 inside the frame 1 to move onto the folding rail 65 via the track 9 for easy handling.

[0029] Preferably, such as Figure 4As shown, the feeding device 3 includes a first guide rail 19 fixed on the frame 1. A first synchronous belt module 20 is provided at the front and rear ends of the first guide rail 19, and a first motor 21 is connected to one end of the first synchronous belt module 20. A first slider 22 is provided on the first guide rail 19, and the first slider 22 slides on the first guide rail driven by the first synchronous belt module 20. A second cylinder 23 is provided at the lower end of the first slider 22, and a suction cup plate 24 is provided at the lower end of the second cylinder 23. Vacuum suction cups 25 are provided at the four corners of the suction cup plate 24. In this embodiment, the flexibility of the vacuum suction cups 25 provides a buffering effect during contact with the photovoltaic module, preventing damage to the surface of the photovoltaic module. Vacuum suction cup 25 is responsible for holding the photovoltaic modules, ensuring they do not fall off due to vibration during transport. Second cylinder 23 controls the vertical movement of vacuum suction cup 25, ensuring its bottom is in full contact with the top surface of the photovoltaic modules when picking them up. First synchronous belt module 20 controls the horizontal movement of vacuum suction cup 25, working with second cylinder 23 to transfer the photovoltaic modules stacked in the storage bin 10 of the loading stacking device one by one to the loading transfer position of the conveyor device 5. The selection of first synchronous belt module 20 also makes the loading device 3 more stable and smooth during the transfer of photovoltaic modules.

[0030] Preferably, such as Figure 5 and Figure 6As shown, the fixed scribing device 4 includes a scribing plate 26 mounted on a frame 1. A scribing platform 27 is provided in the middle of the scribing plate 26. First linear motor modules 28 are provided on both sides of the scribing plate 26. A second linear motor module 29 is slidably mounted between the first linear motor modules 28. A laser 31 is slidably mounted on the second linear motor module 29. Limiters 32 and third cylinders 33 are fixed at opposite corners of the scribing plate 26. The telescopic end of the third cylinder 33 is provided with a corner piece 34. The limiters 32 and the corner piece 34 are used to limit the photovoltaic module. In this embodiment, the scribing platform provides a processing station and installation position for the photovoltaic module and other components. When an unprocessed photovoltaic module is transported to the scribing platform by the conveying device 5, due to slight vibrations that may occur during the transfer, the side of the photovoltaic module may not coincide with the side of the scribing platform 27 when the photovoltaic module is placed at the processing station of the scribing platform by the conveying device 5. At this point, the third cylinder 33 installed on the scribing platform will extend. The V-shaped apex component 34 installed at the front of the cylinder will contact the side of the photovoltaic module and push it towards the limiter 32. When the cylinder extends to its maximum value, the side of the photovoltaic module will approach the limiter 32, and at the same time, the side of the photovoltaic module will coincide with the side of the processing plane, thus ensuring the accuracy of laser scribing. In this embodiment, a TN-10×10 cylinder is selected, with a travel stroke of 10mm. The laser 31 is mounted on a linear motor module, which uses the linear motor module to realize the movement of the X and Y axes. The laser 31 is responsible for the scribing work of the photovoltaic module. A green picosecond laser 31 with a wavelength of 515nm and an average power of 30W is selected.

[0031] Preferably, such as Figure 7 and Figure 8As shown, the conveying device 5 includes a support plate 35 mounted on a frame 1. Multiple first linear slide rails 36 are mounted on the support plate 35, and first linear sliders 37 are mounted on the first linear slide rails 36. Linear slide plates 38 connect the first linear sliders 37, and multiple lifting bearing seats 39 are mounted on the linear slide plates 38. A fourth cylinder 40 is mounted on the support plate 35 and connected to the end of the linear slide plate 38. Lifting rods 41 are mounted at the four corners of the support plate 35, and second lifting rods slidably connect the lifting rods 41. The bottom of the second lifting plate 42 is provided with an inclined lifting block 43 that cooperates with the lifting bearing seat 39. The second lifting plate 42 is also provided with a ball screw module and a second motor 45 that drives the ball screw module 44. A second slider 46 is slidably fitted onto the ball screw module, and a transfer plate 47 is provided on the second slider 46. Lifting plates 48 are vertically arranged on both sides of the transfer plate 47. A long strip-shaped lifting gap 49 is symmetrically arranged on the scribe plate 26, and the lifting gap 49 is used for the lifting of the lifting plates 48. First limiting protrusions 50 are provided at both ends of the lifting plate 48, and a second limiting protrusion 51 is provided in the middle of the lifting plate 48. A groove 52 for placing photovoltaic modules is formed between the first limiting protrusions 50 and the second limiting protrusions 51. In this embodiment, two lifting gaps 49 are designed on the scribing platform, so that the transfer component of the conveying device 5 can pass through the scribing platform to transfer the photovoltaic modules. This design enables the laser scribing machine to independently and continuously process multiple photovoltaic modules while ensuring the positioning accuracy as much as possible. Specifically, the lifting plate 48 is responsible for carrying the photovoltaic modules during the conveying process. It is designed with two grooves 52, which can convey the unprocessed photovoltaic modules to the processing plane of the fixed scribing device 4, and at the same time convey the processed photovoltaic modules on the processing plane to the transfer position of the unloading device 7. This not only improves the conveying efficiency, but also reduces the waiting time of the scribing device of the laser scribing machine during the conveying process, thereby increasing the work efficiency. The ball screw module is driven by the second motor 45 and is responsible for realizing the horizontal movement of the transfer plate 47. The inclined lifting mechanism, which consists of the fourth cylinder 40, the first linear slide rail 36, the lifting bearing seat 39 and the inclined lifting block 43, is responsible for realizing the vertical movement of the second lifting plate 42, thereby driving the lifting plate 48 to rise and fall in the lifting gap 49, ensuring that the unprocessed photovoltaic modules can be lifted and placed on the processing plane.

[0032] Preferably, Figure 9 and Figure 10As shown, the feeding device 7 includes a second guide rail 53 fixed on the frame 1. Second synchronous belt modules 54 are provided at the front and rear ends of the second guide rail 53, and a third motor 55 is connected to one end of the second synchronous belt module 54. A third slider 56 is provided on the second guide rail 53, and the third slider 56 slides on the second guide rail driven by the second synchronous belt module 54. A fifth cylinder 57 is provided at the lower end of the third slider 56, and a mounting plate 58 is provided at the lower end of the fifth cylinder 57. A rotary cylinder 59 is provided in the middle of the bottom surface of the mounting plate 58, and a cross-shaped rotating plate 60 is provided at the rotating end of the rotary cylinder 59. Connecting rods 61 are hinged to the cross ends of the rotating plate 60. Four second linear slide rails 62 are provided on the bottom surface of the mounting plate 58 in a cross shape. Second linear sliders 63 are slidably mounted on the second linear slide rails 62, and hook-shaped lifting plates 64 are provided at the lower ends of the second linear sliders 63. The end of the lifting plate 64 is hinged to the outer end of the connecting rod 61. In this embodiment, the horizontal and vertical movement of the unloading device 7 is the same as that of the loading device 3, using a second synchronous belt module 54 and a fifth cylinder 57. However, the picking mechanism is designed with two pairs of lifting plates 64 that can move face-to-face. When the lifting plates 64 move away from each other, the space formed at the bottom of the picking mechanism is sufficient to accommodate a photovoltaic module. When the picking mechanism completely encloses the photovoltaic module through the movement of the synchronous belt module and the cylinder, the lifting plates 64 move closer to each other. At this time, the bottom of the lifting plates 64 extends under the photovoltaic module, thereby lifting and transferring the photovoltaic module. In this embodiment, the photovoltaic module picking mechanism is composed of four sets of crank-slider components consisting of a rotary cylinder 59, a rotary plate 60, a linear slide rail, and a connecting rod 61. The lifting plates 64 are designed to ensure that during the transfer of the photovoltaic module, they do not directly contact the processed surface of the photovoltaic module but only its bottom surface.

[0033] Working principle

[0034] First, the vacuum suction cup 25 of the loading device 3 picks up an unprocessed photovoltaic module from the loading and stacking device and transports it to the loading and transfer position of the conveying device 5 via the first synchronous belt module 20. Then, the conveying device 5 provides a lifting plate 48 for the transfer position, which moves vertically and horizontally via an inclined lifting mechanism and a ball screw. In addition, since the lifting plate 48 has two photovoltaic module placement grooves 52, when the lifting plate 48 transports the unprocessed photovoltaic module to the laser scribing platform, it also transports the processed photovoltaic module on the platform to the unloading and transfer position. Finally, the unloading device 7 transports the processed photovoltaic module from the unloading and transfer position to the unloading and stacking device. Then, the lifting plate 48 returns to the loading and transfer position to wait for the laser scribing platform to finish scribing, thereby transporting the next photovoltaic module. The entire process is completely completed after the laser scribing machine has processed all the photovoltaic modules in the loading and stacking device and stacked them in the unloading and stacking mechanism.
