Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel processing technology, and in particular to an automatic photovoltaic panel cutting device. Background Technology

[0002] A photovoltaic (PV) panel, or solar photovoltaic panel, is a core component that converts solar energy into electrical energy. It is made up of multiple solar cells connected in series and parallel. During the production process of PV panels, different application scenarios have diverse requirements for the size and shape of PV panels. Therefore, cutting equipment is needed to process PV panels to meet specific specifications. Cutting equipment is a device that can cut and trim PV panels. Most existing PV panel cutting equipment is laser cutting machine, which can cut PV panels according to predetermined sizes and shapes.

[0003] The existing automatic photovoltaic panel cutting equipment has the following shortcomings:

[0004] Firstly, traditional photovoltaic panel positioning methods are rather rudimentary, mostly relying on manual placement and calibration, or simple positioning blocks. In practice, this calibration process is not only cumbersome and time-consuming, but also difficult to guarantee positioning accuracy. Any deviation can lead to the cut photovoltaic panels not meeting size requirements, affecting subsequent assembly and power generation efficiency. Secondly, during laser cutting, the photovoltaic panel material vaporizes and decomposes at high temperatures, producing fumes containing harmful components such as acetic acid, benzene, and formaldehyde, as well as particulate matter like silica dust. Existing equipment often lacks efficient fume treatment devices or is only equipped with simple filtration structures, failing to effectively intercept and adsorb these harmful substances. This results in harmful fumes being directly emitted into the workshop environment, polluting the air and potentially causing respiratory diseases, pneumoconiosis, and other occupational diseases for operators with long-term inhalation. Utility Model Content

[0005] This invention proposes an automatic photovoltaic panel cutting device, which achieves rapid and accurate positioning of photovoltaic panels and deep purification of harmful fumes through innovative positioning components and efficient flue gas treatment components, thereby improving production efficiency and protecting the health of operators, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic photovoltaic panel cutting device, comprising a frame, a cutting worktable fixedly connected to the top of the frame, a gantry frame slidably connected to the top of the frame, a laser cutting head slidably connected to the front side of the top of the gantry frame, a plurality of positioning holes being opened on the top of the cutting worktable, positioning components being slidably inserted into the inner surface of the positioning holes, and a flue gas treatment component being fixedly connected to the front side of the laser cutting head;

[0007] The positioning component includes a positioning pin, which is slidably inserted into the inner surface of a positioning hole. A right-angle connecting plate is fixedly connected to the top of the positioning pin. A fixing component is provided on the top of the right-angle connecting plate. Threaded holes are opened at both ends of the right-angle connecting plate. A right-angle retaining plate is provided on the inner side of the right-angle connecting plate. Limiting grooves are opened on both sides of the outer surface of the right-angle retaining plate. A limiting slider is slidably connected inside the limiting groove. An adjusting bolt is fixedly connected to the side of the limiting slider. The outer surface of the adjusting bolt is threadedly connected to the inner surface of the threaded hole.

[0008] Preferably, the fixing component includes a pull rod, which is slidably connected to the top of the right-angle connecting plate. A sliding groove is formed inside the positioning pin. The bottom end of the pull rod passes through the interior of the sliding groove and is movably connected to the connecting plate. The bottom end of the connecting plate is fixedly connected to the sliding plate.

[0009] Preferably, the sliding plate is slidably connected inside the sliding groove, one end of the sliding plate is fixedly connected to a clamping spring, the end of the clamping spring away from the sliding plate is fixedly connected to the inner wall of the sliding groove, a positioning slot is formed at the bottom end of the positioning hole, and the other end of the sliding plate extends through the interior of the positioning slot.

[0010] Preferably, the flue gas treatment component includes a duct, which is fixedly connected to the front side of the laser cutting head, and metal dustproof mesh is fixedly connected to both the upper and lower ends of the inner surface of the duct.

[0011] Preferably, a cross bracket is fixedly connected to the top of the inner surface of the air duct, an electric motor is fixedly connected to the middle of the cross bracket, and the output shaft of the electric motor is fixedly connected to the guide fan.

[0012] Preferably, an activated carbon fiber mesh is fixedly connected to the lower part of the inner surface of the air duct, and a HEPA high-efficiency filter mesh is fixedly connected to the middle part of the inner surface of the air duct.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. In this utility model, the rapid and precise positioning of photovoltaic panels is achieved through the cooperation of positioning pins, right-angle connecting plates, right-angle clamping plates, adjusting bolts, and fixing components. In use, the four positioning pins are first inserted into the positioning holes on the top of the cutting table. The sliding clamping plate is then driven into the positioning slot by the pull rod in the fixing component. The spring force of the top spring firmly fixes the positioning pins in the positioning holes, ensuring the right-angle connecting plate is stably placed above the cutting table. Subsequently, the right-angle clamping plate is installed inside the right-angle connecting plate via a limiting slider and adjusting bolt. By rotating the adjusting bolt, the right-angle clamping plate moves along the limiting groove under the action of threaded transmission, allowing for precise clamping and positioning of the photovoltaic panel according to its dimensions. This positioning method allows operators to quickly complete the positioning by simply placing the photovoltaic panel between the four right-angle clamping plates, eliminating the need for cumbersome calibration operations like traditional equipment. This significantly improves production efficiency while ensuring positioning accuracy, effectively avoiding the problem of substandard cutting dimensions due to positioning deviations.

[0015] 2. In this invention, a highly efficient flue gas treatment system is constructed through the coordinated operation of an electric motor, a guide fan, a metal dustproof mesh, an activated carbon fiber mesh, and a HEPA high-efficiency filter. During the laser cutting of photovoltaic panels, the electric motor drives the guide fan to rotate, generating suction that causes the flue gas generated during cutting to quickly flow into the air duct. The flue gas first passes through the metal dustproof mesh at the bottom of the inner surface of the air duct, intercepting larger dust and debris particles; then it passes through the activated carbon fiber mesh, whose rich microporous structure and huge specific surface area can efficiently adsorb harmful organic gases such as acetic acid, benzene, and formaldehyde; finally, it flows through the HEPA high-efficiency filter, which effectively filters fine particulate matter, including ultrafine silica dust. The three-layer filtration structure works synergistically to achieve graded and deep purification of harmful flue gas. Compared with existing equipment, this greatly reduces the pollution of the environment by harmful flue gas, while effectively protecting the health of operators and reducing the risk of occupational diseases.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] 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 in the following specification.

[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an automatic photovoltaic panel cutting device, including a frame 1, a cutting worktable 2 fixedly connected to the top of the frame 1, a gantry frame 4 slidably connected to the top of the frame 1, a laser cutting head 5 slidably connected to the front side of the top of the gantry frame 4, a plurality of positioning holes 21 opened on the top of the cutting worktable 2, positioning components 3 slidably inserted into the inner surface of the positioning holes 21, a flue gas treatment component 6 fixedly connected to the front side of the laser cutting head 5, and the positioning component 3 including positioning posts 31, the positioning posts 31 slidably inserted into the positioning... The inner surface of the insertion hole 21 is fixedly connected to the top of the positioning insertion post 31 with a right-angle connecting plate 32. The top of the right-angle connecting plate 32 is provided with a fixing component 33. Threaded holes 34 are opened at both ends of the right-angle connecting plate 32. A right-angle clamping plate 35 is provided on the inner side of the right-angle connecting plate 32. Limiting grooves 36 are opened on both sides of the outer surface of the right-angle clamping plate 35. Limiting sliders 37 are slidably connected inside the limiting grooves 36. Adjusting bolts 38 are fixedly connected to the side of the limiting sliders 37. The outer surface of the adjusting bolts 38 is threadedly connected to the inner surface of the threaded hole 34.

[0024] like Figure 3As shown, the fixing component 33 includes a pull rod 331, which is slidably connected to the top of the right-angle connecting plate 32. A sliding groove is opened inside the positioning pin 31. The bottom end of the pull rod 331 passes through the inside of the sliding groove and is movably connected to the connecting plate 332. The bottom end of the connecting plate 332 is fixedly connected to the sliding plate 333. Here, when the positioning component 3 needs to be installed, the pull rod 331 is pulled upward, which drives the connecting plate 332 and the sliding plate 333 to slide, so that the sliding plate 333 retracts into the sliding groove of the positioning pin 31. At this time, the positioning pin 31 is inserted into the positioning hole 21. After insertion, the pull rod 331 is released. Under the elastic force of the tightening spring 334, the sliding plate 333 automatically pops out and is locked into the positioning slot 22, realizing a firm connection between the positioning pin 31 and the cutting worktable 2. The operation is simple and the connection is stable, ensuring the reliability of subsequent positioning and cutting work.

[0025] like Figure 3 As shown, the sliding plate 333 is slidably connected inside the sliding groove. One end of the sliding plate 333 is fixedly connected to the clamping spring 334, and the end of the clamping spring 334 away from the sliding plate 333 is fixedly connected to the inner wall of the sliding groove. The bottom end of the positioning hole 21 is provided with a positioning slot 22, and the other end of the sliding plate 333 extends into the interior of the positioning slot 22. Here, this structure provides continuous elastic force through the clamping spring 334 to ensure that the sliding plate 333 and the positioning slot 22 fit tightly, preventing the positioning post 31 from loosening or falling off during use, further enhancing the stability of the positioning component 3 installation, and providing a strong guarantee for the accurate positioning of the photovoltaic panel.

[0026] like Figure 4 As shown, the flue gas treatment component 6 includes a duct 61, which is fixedly connected to the front side of the laser cutting head 5. Metal dustproof mesh 62 is fixedly connected to both the upper and lower ends of the inner surface of the duct 61. Here, the upper metal dustproof mesh 62 can prevent external debris from entering the duct 61 and affecting the operation of the equipment, while the lower metal dustproof mesh 62 serves as the first line of defense for flue gas filtration, intercepting larger particles of dust and debris generated by laser cutting, preventing them from entering the subsequent filtration structure and causing blockage, while also initially purifying the flue gas and reducing the burden on the subsequent filtration layers.

[0027] like Figure 4 As shown, a cross bracket 63 is fixedly connected to the top of the inner surface of the ventilation duct 61, and an electric motor 64 is fixedly connected to the middle of the cross bracket 63. The output shaft of the electric motor 64 is fixedly connected to a guide fan 65. Here, when laser cutting photovoltaic panels, the electric motor 64 is started, and the electric motor 64 drives the guide fan 65 to rotate at high speed, forming a negative pressure inside the ventilation duct 61 and generating suction. This suction can promptly draw harmful fumes generated near the laser cutting head 5 into the ventilation duct 61 and push the fumes to flow inside the ventilation duct 61, allowing them to pass through each layer of filter structure in sequence, thus achieving effective collection and transportation of harmful fumes.

[0028] like Figure 4 As shown, an activated carbon fiber mesh 66 is fixedly connected to the lower inner surface of the air duct 61, and a HEPA high-efficiency filter 67 is fixedly connected to the middle of the inner surface of the air duct 61. Here, when the flue gas containing harmful gases and fine particulate matter enters the air duct 61 under the action of the guide fan 65, it first passes through the metal dustproof mesh 62 at the lower end to intercept larger particulate impurities; then the flue gas flows upward and passes through the activated carbon fiber mesh 66, which utilizes its rich microporous structure and huge specific surface area to efficiently adsorb harmful organic gases such as acetic acid, benzene, and formaldehyde in the flue gas; finally, the flue gas passes through the HEPA high-efficiency filter 67, which can effectively remove fine particulate matter, including ultrafine silica dust. Through the synergistic treatment of the three-layer filtration structure, the harmful flue gas is deeply purified, and the purified gas is then discharged from the air duct 61, reducing harm to the environment and operators.

[0029] The usage method and working principle of this device are as follows: Before use, according to the size of the photovoltaic panel to be cut, insert the four positioning pins 31 into the positioning holes 21 at appropriate positions on the top of the cutting workbench 2. When inserting, first pull the pull rod 331 upward to retract the sliding plate 333 into the positioning pin 31. After inserting into the positioning hole 21, release the pull rod 331 and tighten the spring 334 to push the sliding plate 333 into the positioning slot 22 to complete the fixing of the positioning pins 31. Then, install the right angle plate 35 on the inside of the right angle connecting plate 32 through the limiting slider 37 and the adjusting bolt 38. Rotate the adjusting bolt 38 to move the right angle plate 35 along the limiting slide groove 36 to adjust the size of the space enclosed by the four right angle plates 35 to match the size of the photovoltaic panel. Place the photovoltaic panel between the four right angle plates 35 to complete the positioning of the photovoltaic panel.

[0030] After positioning is completed, the equipment is started. The gantry 4 slides on the top of the frame 1, driving the laser cutting head 5 to move above the position to be cut on the photovoltaic panel. By controlling the back-and-forth sliding of the laser cutting head 5 on the gantry 4 and the lateral and longitudinal movement of the gantry 4, the position and angle of the laser cutting head 5 are precisely adjusted so that it is aligned with the cutting path.

[0031] During the cutting process, the electric motor 64 in the flue gas treatment component 6 is started simultaneously. The electric motor 64 drives the guide fan 65 to rotate, creating a negative pressure in the air duct 61, which draws the harmful fumes generated by laser cutting into the air duct 61. The fumes pass through the lower metal dustproof mesh 62, the activated carbon fiber mesh 66, and the HEPA high-efficiency filter 67 in sequence, achieving step-by-step filtration and adsorption of particulate impurities and harmful gases in the harmful fumes. The purified gas is then discharged. After the cutting is completed, the gantry 4 drives the laser cutting head 5 to reset, and the cut photovoltaic panel is taken out. If it is necessary to continue cutting photovoltaic panels of different sizes, the above positioning and cutting steps can be repeated.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
