Description

Technical Field

[0001] This invention belongs to the technical field of photovoltaic module processing equipment, and specifically relates to a processing device for a photovoltaic module frame. Background Technology

[0002] With the rapid development of the photovoltaic industry, the demand for lightweight, corrosion-resistant, and low-cost photovoltaic modules is becoming increasingly prominent. Basalt fiber composite materials, due to their excellent specific strength, corrosion resistance, and insulation properties, are gradually becoming an ideal material to replace traditional aluminum alloy frames. Basalt fiber composite photovoltaic frames are typically produced by pultrusion molding into long strip profiles, which are then cut to the required dimensions for frame fabrication based on the size of the photovoltaic module.

[0003] However, existing profile cutting equipment still has some shortcomings when processing such composite materials: Firstly, for special materials such as basalt fiber composite frame profiles, existing equipment mostly uses mechanical sawing or manual cutting in the cutting process. Mechanical sawing is noisy, produces a lot of dust, and results in poor cut surface quality. While laser cutting can improve cutting quality, it generates a large amount of high-temperature dust when processing composite materials. Existing equipment has a relatively simple method for handling the dust generated during cutting, such as simply installing a dust collection hood above the equipment for overall dust extraction. This method is energy-intensive, has low dust extraction efficiency, and it is difficult to create an effective negative pressure at the cutting point, causing dust to easily spread into the workshop environment. This not only pollutes the working environment and endangers the health of operators, but may also affect the lifespan of the equipment due to dust intrusion into its precision components. In addition, existing cutting equipment generally requires workers to move the profiles to be processed one by one to the cutting station and measure the cutting position before cutting. This is not only labor-intensive, but also slow in loading, making it difficult to meet the needs of large-scale production. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a processing device for photovoltaic module frames, which can realize automatic material conveying, cutting and dust extraction, and use material discharge impact to drive the filter screen self-cleaning, thereby improving processing efficiency and environmental protection.

[0005] The specific technical solution adopted by this invention is as follows: A processing apparatus for photovoltaic module frames includes a worktable and a conveying assembly disposed on the worktable, wherein a guide plate is disposed at the end of the worktable, and further includes: A cutting assembly, comprising a cutting feed platform on a worktable and a laser cutting head mounted on the cutting feed platform, the laser cutting head being provided with an abutment; Multiple guide components are spaced apart on the worktable along the conveying direction of the conveying assembly, and are used to guide and limit the profile conveyed by the conveying assembly through two adjacent guide components; A limiting component is disposed downstream of the guide component along the conveying direction to limit the conveying distance of the profile; A fixing component is disposed between two adjacent guide members for fixing the profile during cutting; A dust extraction assembly, comprising a dust extraction section disposed on a workbench, a filter section connected to the dust discharge end of the dust extraction section, and a cleaning section disposed on the filter section; The receiving assembly is located at the right end of the workbench and is used to receive the cut profiles. It rotates under pressure to drive the cleaning unit to work.

[0006] In a preferred embodiment, the conveying assembly includes multiple rotating rollers, which are rotatably connected to a worktable via bearings. A transmission gear is fixedly mounted at the end of each rotating roller, and a motor is fixedly mounted on the worktable, with the output shaft of the motor fixedly connected to the central shaft of one of the rotating rollers.

[0007] In a preferred embodiment, the abutment includes two first trapezoidal blocks, both of which are fixedly connected to the laser cutting head, and a second trapezoidal block is fixedly connected to one of the first trapezoidal blocks via a support rod.

[0008] In a preferred embodiment, the limiting component includes two movable slots, which are respectively opened on the front and rear guide members. A slider is slidably connected in the movable slot, and a round rod is fixedly connected between the two sliders. Multiple support frames are fixedly connected to the round rod, and multiple baffles are rotatably connected in an array on the round rod, with the baffles located between two adjacent guide members. A force-bearing rod is fixedly connected to the top of the baffle, and a first torsion spring is fixedly connected between the baffle and the support frame. A hollow cylinder is fixedly connected to the support frame, and a micro-hole is opened at the top of the hollow cylinder. A piston rod is piston-type inserted into the upper end of the hollow cylinder, and the lower end of the piston rod extends to the outside of the hollow cylinder. A piston plate is fixedly sleeved on the piston rod, and the piston plate is slidably connected inside the hollow cylinder. An air inlet pipe is fixedly connected to the upper end of the hollow cylinder.

[0009] In a preferred embodiment, the limiting component further includes a slide rail, which is fixedly connected to the guide member, and a lifting seat is slidably connected to the slide rail. A first compression spring is sleeved on the lower end of the slide rail.

[0010] In a preferred embodiment, the fixing assembly includes an n-shaped frame, which is fixedly connected to two adjacent guide members. A lifting rod is slidably inserted into the n-shaped frame, and a pressure block is fixedly connected to the lower end of the lifting rod. A lifting plate is fixedly connected to the lifting rod, and a second compression spring is connected between the lifting plate and the n-shaped frame. A vertical rod is fixedly connected to the lifting plate, and the lower end of the vertical rod passes through the guide member.

[0011] In a preferred embodiment, the dust extraction unit includes a dust extraction machine, which is fixedly mounted on a bracket on a workbench. The dust extraction end of the dust extraction machine is fixedly connected to a dust extraction pipe, and multiple dust extraction hoods are fixedly connected to the dust extraction pipe. Both ends of each dust extraction hood are connected to a hollow shell, and a sealing plate is slidably inserted into the hollow shell. A guide groove is also provided on the hollow shell, and a crossbar is slidably connected in the guide groove. The middle end of the crossbar is fixedly connected to the sealing plate, and the end end is fixedly connected to a vertical rod.

[0012] In a preferred embodiment, the filtration unit includes a filter box, which is fixedly connected to the dust discharge end of the dust collector. One end of the filter box is fixedly connected to a filter, and a filter plate is fixedly connected inside the filter box. The filter plate has air vents arranged in an array on its arc-shaped end.

[0013] In a preferred embodiment, the cleaning unit includes a first rotating rod, which is rotatably connected to the filter box via a bearing. A brush plate is fixedly mounted on the first rotating rod, and a scraper is fixedly connected to the filter plate. A first gear is fixedly mounted at both ends of the first rotating rod. A second rotating rod is rotatably connected to the support of the filter box via a bearing, and a second gear and a third gear are fixedly mounted on the second rotating rod.

[0014] In a preferred embodiment, the receiving assembly includes a third rotating rod, which is rotatably connected to the worktable via a bearing. Multiple receiving rods are fixedly connected to the third rotating rod, and a through slot is provided on the guide plate for the receiving rods to pass through. A second torsion spring is fitted at both ends of the third rotating rod, with one end of the second torsion spring fixedly connected to the worktable and the other end fixedly connected to the receiving rod. A fourth gear is also fixedly installed on the third rotating rod.

[0015] The technical effects achieved by this invention are as follows: This invention utilizes a sealing plate structure in the dust extraction section, controlled by a fixed assembly, to ensure that the dust extraction hood only opens to create negative pressure at the workstation where the profile is clamped and about to be cut. This "on-demand dust extraction" mode avoids the energy waste caused by the continuous high-power operation of traditional equipment, while ensuring that the high-temperature fiber dust generated during laser cutting of basalt fiber composite materials is sucked in nearby. Combined with the dual filtration mechanism of the large-particle settling filter plate and the high-efficiency filter in the filtration section, it effectively prevents dust from overflowing and polluting the workshop, protects the respiratory health of operators, reduces dust erosion of precision equipment components, and extends the equipment's service life. This invention utilizes a contact element driven by the movement of the laser cutting head to sequentially trigger the delayed reset mechanisms of the fixing and limiting components. Specifically, the contact element first presses down on the fixing component to firmly clamp the profile, and then forcibly rotates the limiting baffle to create space for the cut profile to flip. This mechanical timing control ensures the stability of the cutting process and solves the problem of interference between the cut profile and the limiting mechanism. After being cut, the profile flips and falls to the receiving component by gravity. During loading, a conveying component with multiple guides provides stable guidance for the profile transport, eliminating the need for manual handling and measurement. This not only reduces labor intensity but also ensures the consistency of fixed-length cutting, meeting the needs of large-scale continuous production. This invention establishes a "cutting-receiving-cleaning" linkage mechanism, realizing the equipment's self-maintenance function. Utilizing the impact force and rotational potential energy generated when the receiving component receives the cut profile, a gear transmission mechanism drives the cleaning section of the filter. Each time a cutting and receiving action is completed, the rotation of the receiving rod causes the brush plate to automatically clean the dust accumulated on the filter plate surface, and the scraper performs self-cleaning of the brush bristles. This design utilizes the "waste force" generated during processing, which is not only energy-saving and environmentally friendly but also ensures the long-term smooth operation of the filtration system, avoiding a decrease in dust collection efficiency due to filter clogging, and greatly improving the reliability and stability of equipment operation.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0021] Please see the appendix Figures 1 to 4 As shown, this embodiment provides a processing apparatus for photovoltaic module frames, including a workbench 1 and a conveying assembly 11 disposed on the workbench 1. A guide plate 12 is disposed at the end of the workbench 1, and the apparatus further includes: Cutting assembly 2 includes a cutting feed platform 21 set on the worktable 1 and a laser cutting head 22 installed on the cutting feed platform 21. The laser cutting head 22 is provided with an abutment 23. Multiple guide members 3 are spaced apart on the worktable 1 along the conveying direction of the conveying assembly 11, and are used to guide and limit the profile conveyed by the conveying assembly 11 through two adjacent guide members 3; Limiting component 4 is located downstream of the guide component 3 along the conveying direction and is used to limit the conveying distance of the profile. Fixing component 5 is disposed between two adjacent guide components 3 and is used to fix the profile during cutting; The dust extraction assembly 6 includes a dust extraction section 61 disposed on the workbench 1, a filter section 62 connected to the dust discharge end of the dust extraction section 61, and a cleaning section 63 disposed on the filter section 62. The receiving assembly 7 is located at the right end of the workbench 1. It is used to receive the cut profiles and rotates under pressure to drive the cleaning unit 63 to work.

[0022] In this embodiment, after the conveying assembly 11 is started, it will convey the profile to be processed along the worktable 1. During the conveying process, multiple guide components 3 guide and limit the profile to ensure that the profile maintains a stable and accurate path during conveying, avoids deviation, and lays a good foundation for the subsequent cutting process.

[0023] When the profile is conveyed to the position of the limiting component 4, the limiting component 4 will limit the conveying distance of the profile according to preset parameters. The fixing component 5 can fix the profile during cutting, preventing the profile from moving when the laser cutting head 22 is cutting, thereby ensuring the accuracy and quality of cutting. The cutting feed platform 21 in the cutting component 2 will move according to the cutting requirements, driving the laser cutting head 22 mounted on it to the appropriate cutting position. The laser cutting head 22 emits a high-energy laser beam to cut the profile.

[0024] During the cutting process, the dust extraction unit 61 of the dust extraction component 6 will be activated in a timely manner, using powerful suction to draw the dust and debris into the filter unit 62 for filtration. The filter unit 62 can effectively separate the dust and debris, ensuring that the exhaust air meets environmental protection requirements. The cleaning unit 63 will regularly clean and maintain the filter unit 62 to prevent dust accumulation from affecting the filtration effect.

[0025] After cutting, the cut profile is conveyed to the receiving assembly 7. The receiving assembly 7 receives the profile, and when the weight of the profile exerts pressure on it, the receiving assembly 7 will rotate. This rotation generates a certain amount of power, which in turn drives the cleaning unit 63 to work, realizing the linkage and efficient operation between various parts of the device.

[0026] It should be noted that the cutting feed platform 21 and the laser cutting head 22 are both products that are currently available on the market. When selecting them, the requirements of this application should be met as much as possible, provided that the specifications and usage scenarios are suitable. Specific models and specifications are not limited here.

[0027] Secondly, please refer to again Figure 1 The conveying assembly 11 includes multiple rotating rollers 111, which are rotatably connected to the worktable 1 via bearings. A transmission gear 112 is fixedly installed at the end of each rotating roller 111. A motor 113 is fixedly installed on the worktable 1, and the output shaft of the motor 113 is fixedly connected to the central shaft of one of the rotating rollers 111.

[0028] In this embodiment, the transmission gears 112 on the multiple rotating rollers 111 are driven by toothed belts. After the motor 113 is started, it drives one of the rotating rollers 111 to rotate, thereby causing all the rotating rollers 111 to rotate synchronously. The strip profile to be processed is placed on the worktable 1 and positioned between two adjacent guide members 3. The guide members 3 are spaced apart along the conveying direction, providing guidance and limiting for the movement of the profile, ensuring that it moves stably along the preset path.

[0029] In addition, the guide component 3 is provided with a cutting groove located below the laser cutting head 22, dividing the guide component 3 into two sections. The left section is fixedly connected to the worktable 1 by a bracket, and the guide component 3 does not contact the rotating roller 111, while the right section of the guide component 3 is directly fixedly connected to the guide plate 12.

[0030] Secondly, please refer to Figure 2 The contact element 23 includes two first trapezoidal blocks 231, both of which are fixedly connected to the laser cutting head 22. A second trapezoidal block 232 is fixedly connected to one of the first trapezoidal blocks 231 via a support rod.

[0031] Secondly, please refer to again Figures 9 to 11 The limiting component 4 includes two moving grooves 41, which are respectively opened on the front and rear guide members 3. A slider 42 is slidably connected in the moving groove 41. A round rod 43 is fixedly connected between the two sliders 42. Multiple support frames 44 are fixedly connected to the round rod 43. Multiple baffles 45 are rotatably connected in an array on the round rod 43. The baffles 45 are located between two adjacent guide members 3. A force rod 46 is fixedly connected to the top of the baffle 45. A first torsion spring 47 is fixedly connected between the baffle 45 and the support frame 44. A hollow cylinder 48 is fixedly connected to the support frame 44. A micro-hole is opened at the top of the hollow cylinder 48. A piston rod 49 is piston-type inserted into the upper end of the hollow cylinder 48. The lower end of the piston rod 49 extends to the outside of the hollow cylinder 48. A piston plate 410 is fixedly sleeved on the piston rod 49. The piston plate 410 is slidably connected inside the hollow cylinder 48. An air inlet pipe 411 is fixedly connected to the upper end of the hollow cylinder 48.

[0032] In this embodiment, when the profile is conveyed to the limiting component 4, its end abuts against the baffle 45. The baffle 45 initially acts as a blocker for the profile. Although the profile continues to be driven by the rotating roller 111, it slips on the roller 111 due to the obstruction, thus stopping its forward movement. The distance from directly below the laser cutting head 22 to the baffle 45 is the preset profile cutting length. The operator can flexibly adjust the cutting length by adjusting the position of the slider 42 within the moving groove 41, thereby changing the distance between the round rod 43 and the baffle 45 relative to the cutting component 2.

[0033] Subsequently, the cutting assembly 2 begins operation. The cutting feed platform 21 drives the laser cutting head 22 to move towards the profile. During this process, the contact member 23, which is fixedly connected to the laser cutting head 22, will first contact the triggering parts of the fixing assembly 5 and the limiting assembly 4.

[0034] It should be noted that the slider 42 can move along the moving groove 41 and is fixed by bolts. By loosening the bolts fixing the slider 42, the slider 42 can move along the moving groove 41, thereby driving the round rod 43 and the entire baffle 45 mechanism mounted on it to move synchronously, thereby adjusting the relative distance between the baffle 45 and the laser cutting head 22, and finally realizing the setting of different cutting lengths.

[0035] Please refer to it again. Figure 8 and Figure 9 The fixing component 5 includes an n-shaped frame 51, which is fixedly connected to two adjacent guide components 3. A lifting rod 52 is slidably inserted into the n-shaped frame 51. A pressure block 53 is fixedly connected to the lower end of the lifting rod 52. A lifting plate 54 is fixedly connected to the lifting rod 52. A second compression spring 55 is connected between the lifting plate 54 and the n-shaped frame 51. A vertical rod 56 is fixedly connected to the lifting plate 54, and the lower end of the vertical rod 56 passes through the guide component 3.

[0036] In this embodiment, when the first trapezoidal block 231 moves above the lifting rod 52 of the fixing assembly 5, it presses down the lifting rod 52. The downward movement of the lifting rod 52 causes the pressure block 53 to press the profile, while simultaneously compressing the second compression spring 55. Furthermore, the first trapezoidal block 231 contacts and presses down the lifting rod 52 before the laser cutting head 22 cuts the profile, thereby firmly pressing the profile before cutting to prevent it from moving and ensure cutting accuracy. The lower end of the pressure block 53 is preferably made of rubber to protect the surface of the profile and increase friction.

[0037] Please refer to it again. Figure 4 , Figure 5 and Figure 8 The dust extraction unit 61 includes a dust extraction machine 611, which is fixedly mounted on a bracket on the workbench 1. The dust extraction end of the dust extraction machine 611 is fixedly connected to a dust extraction pipe 612. Multiple dust extraction hoods 613 are fixedly connected to the dust extraction pipe 612. Both ends of the dust extraction hood 613 are connected to hollow shells 614. A sealing plate 615 is slidably inserted into the hollow shell 614. A guide groove 616 is also provided on the hollow shell 614. A crossbar 617 is slidably connected in the guide groove 616. The middle end of the crossbar 617 is fixedly connected to the sealing plate 615, and the end end is fixedly connected to the vertical rod 56.

[0038] In this embodiment, the dust extraction assembly 6 is activated simultaneously with the cutting process. The dust extraction machine 611 operates, generating negative pressure within the dust extraction hood 613 via the dust extraction pipe 612. However, not all dust extraction hoods 613 are operational. The opening and closing of the sealing plate 615 within its hollow shell 614 is controlled by the vertical rod 56 of the fixing assembly 5 via the horizontal rod 617. When a profile at a certain position is fixed by the pressure block 53, the vertical rod 56 at that position is pressed down, causing the horizontal rod 617 to slide down along the guide groove 616, thereby causing the sealing plate 615 to move downward, opening the air extraction channel of the dust extraction hood 613, rapidly establishing negative pressure inside, and drawing in the high-temperature, fine basalt fiber dust generated by laser cutting. Furthermore, the ports of the dust extraction hoods 613 not located at the cutting station remain sealed by their corresponding sealing plates 615. This method establishes negative pressure only within the dust extraction hood 613 at the profile to be cut, effectively collecting the dust generated during the cutting process and preventing it from spreading into the surrounding environment. On one hand, this effectively reduces the dust concentration in the workshop, improves the working environment, protects the health of operators, and reduces the health risks such as respiratory diseases caused by dust inhalation. On the other hand, it also prevents dust from contaminating and damaging other components of the processing equipment, extending the equipment's service life. Moreover, this targeted dust extraction method improves dust extraction efficiency; compared to general dust extraction, it achieves better dust extraction results with less energy consumption, reducing energy consumption and production costs.

[0039] Please refer to it again. Figures 5 to 7 The filtration unit 62 includes a filter box 621, which is fixedly connected to the dust discharge end of the dust collector 611. A filter 622 is fixedly connected to one end of the filter box 621. A filter plate 623 is fixedly connected inside the filter box 621, and air vents are arranged in an array on the arc-shaped end of the filter plate 623. The filter 622 filters harmful gases and uses existing technology, which will not be described in detail here. A slag discharge trough and a sealing door are provided at the lower end of the filter box 621.

[0040] In this embodiment, the dust-laden gas being drawn in first enters the filter box 621 of the filter section 62. Large dust particles in the airflow are blocked and settled by the filter plate 623, and the remaining gas undergoes secondary filtration through the filter 622 to ensure that the gas discharged into the workshop environment is clean and harmless. When the cutting is completed, the laser cutting head 22 is removed, the pressure of the first trapezoidal block 231 on the lifting rod 52 disappears, and the lifting rod 52 moves upward rapidly under the reset action of the second compression spring 55, causing the pressure block 53 to loosen the profile. At the same time, the vertical rod 56 moves upward, and through the horizontal rod 617, it drives the sealing plate 615 to reset, cutting off the negative pressure of the dust extraction hood 613. This achieves precise dust extraction only at the cutting point, greatly improving dust extraction efficiency and reducing energy consumption.

[0041] Please refer to it again. Figures 6 to 7The cleaning unit 63 includes a first rotating rod 631, which is rotatably connected to the filter box 621 via bearings. A brush plate 632 is fixedly installed on the first rotating rod 631, and a scraper 633 (composed of multiple arc-shaped scraper blades) is fixedly connected to the filter plate 623. A first gear 634 is fixedly installed at both ends of the first rotating rod 631. A second rotating rod 635 is rotatably connected to the support of the filter box 621 via bearings. A second gear 636 and a third gear 637 are fixedly installed on the second rotating rod 635.

[0042] Please refer to it again. Figures 2 to 4 The receiving assembly 7 includes a third rotating rod 71, which is rotatably connected to the workbench 1 via bearings. Multiple receiving rods 72 are fixedly connected to the third rotating rod 71, and a through slot is provided on the guide plate 12 for the receiving rods 72 to pass through. A second torsion spring 73 is sleeved on both ends of the third rotating rod 71, and one end of the second torsion spring 73 is fixedly connected to the workbench 1, and the other end is fixedly connected to the receiving rod 72. A fourth gear 74 is also fixedly installed on the third rotating rod 71.

[0043] In this embodiment, after the profile is cut, it loses the clamping force of the fixing component 5, and its cut section flips downward under the action of gravity and falls. The falling profile will hit the receiving rod 72 of the receiving component 7. After being impacted, the receiving rod 72 rotates downward, driving the third rotating rod 71 to rotate and torsion the second torsion spring 73. This process effectively absorbs the impact force of the falling profile, plays a buffering role, avoids deformation or damage to the profile due to direct collision, and significantly reduces noise.

[0044] The rotation of the third rotating rod 71 also drives the fourth gear 74 on it to rotate. The fourth gear 74 meshes with the second gear 636, driving the second rotating rod 635 and the third gear 637 to rotate. The third gear 637 then drives the first gear 634, which is connected to it via a toothed belt, causing the first rotating rod 631 and the brush plate 632 to rotate. During rotation, the brush plate 632 cleans the surface of the filter plate 623, brushing off the dust adhering to it and preventing the air vents from becoming clogged. This design allows the filter plate 623 to be automatically cleaned after each cutting and receiving operation, maintaining its filtration efficiency. When the brush plate 632 continues to rotate until it contacts the scraper 633, the scraper 633 penetrates into the bristles to scrape off the dust that is wrapped around or accumulated on the bristles, achieving self-cleaning of the brush plate 632.

[0045] Please refer to it again. Figures 9 to 11 The limiting component 4 also includes a slide rail 412, which is fixedly connected to the guide component 3. A lifting seat 413 is slidably connected to the slide rail 412, and a first compression spring 414 is sleeved on the lower end of the slide rail 412.

[0046] In this embodiment, to ensure that the cut profile has sufficient space to flip and fall smoothly and avoid being stuck by the baffle 45, a delayed reset mechanism is provided, specifically: When the laser cutting head 22 moves the contact member 23, the first trapezoidal block 231 on the contact member 23 first contacts and presses down the lifting rod 52, so that the fixing component 5 fixes the profile before cutting. Then, as the laser cutting head 22 continues to move, the second trapezoidal block 232 on the contact member 23 contacts and presses down the lifting seat 413. The lifting seat 413 slides down along the slide rail 412, compressing the first compression spring 414, and simultaneously pressing down the piston rod 49. The piston rod 49 drives the piston plate 410 to move down in the hollow cylinder 48, and draws in air through the air inlet pipe 411 (which is equipped with a one-way valve that only allows air to enter, not shown in the figure). The lower end of the piston rod 49 presses down the force rod 46, forcing the baffle 45 to overcome the elastic force of the first torsion spring 47 and forcibly flip, thereby making space for the end of the profile before cutting and avoiding interference between the profile and the baffle 45 after cutting.

[0047] After the cutting is completed and the second trapezoidal block 232 moves away with the laser cutting head 22, the lifting seat 413 returns to its original position under the rebound force of the first compression spring 414. However, since there is only one micro-hole at the upper end of the hollow cylinder 48 for the gas to slowly escape, the negative pressure formed above the piston plate 410 during the previous downward action cannot be eliminated immediately, causing the piston rod 49 to fail to retract quickly. Therefore, the piston rod 49 will continue to press down on the force rod 46 for a period of time, thus keeping the baffle 45 in a flipped position. This delay provides sufficient time for the just-cut profile to complete the flipping, falling, and receiving process. After the air is slowly discharged from the hollow cylinder 48 through the micro-hole and the internal air pressure is balanced, the piston rod 49, baffle 45, and force rod 46 are fully reset under the action of the first torsion spring 47, and the baffle 45 stands up again, ready to limit the subsequent delivery of profiles. This cycle repeats continuously, efficiently, precisely, and cleanly automating the processing of photovoltaic module frame profiles.

[0048] The working principle of this invention is as follows: The profile is conveyed by the conveying component 11 to the limiting component 4 and stops. The cutting feed platform 21 drives the laser cutting head 22 to move. The contact part 23 on it first presses down the fixing component 5 to press the profile tightly, and then presses down the limiting component 4 to make room for flipping. At the same time, the linkage action of the fixing component 5 opens the dust extraction hood 613 corresponding to the cutting point of the dust extraction unit 61 and starts precise dust extraction. After the laser cutting is completed, all components are reset, and the cut profile segment flips and falls to the receiving component 7. Its impact force drives the receiving rod 72 to rotate, which in turn drives the cleaning unit 63 to automatically clean the filter plate 623 of the filtering unit 62, realizing the fully automated linkage of cutting, dust removal, material feeding and self-cleaning.
