The slider 12 slides on the inner walls of the two No. 1 sliding grooves 11 respectively, and is used to drive the laser cutter 16 to move forward and backward. The No. 2 electric slider 14 drives the laser cutter 16 at the bottom of the connecting frame 15 to slide on the fixed frame 13, and is used to drive the laser cutter 16 to move left and right. The smoke box 17 moves to the upper position of the photovoltaic panel with the laser cutter 16, and the output end of the laser cutter 16 starts laser cutting. The generated smoke and dust can enter the interior of the smoke box 17 and then be extracted by the purification mechanism, so that the smoke and dust first enter the interior of the smoke box 17, and then enter the interior of the purification mechanism for purification, thereby reducing the accumulation of harmful gases and reducing the harm of harmful gases to the human body. At the same time, the smoke box 17 is used to shield the cutting position when cutting the photovoltaic panel, reduce the collision of foreign objects with the output end of the laser cutter 16, and reduce the noise pollution generated during cutting.

[0029] like Figures 1 to 4As shown, the purification mechanism includes a smoke extraction pipe 2, a purification box 21, a fixing plate 22, a servo motor 23, an exhaust fan blade 24 and a filter assembly; the smoke extraction pipe 2 is fixedly connected to the outside of the smoke extraction box 17; the purification box 21 is fixedly connected to the end of the smoke extraction pipe 2 away from the smoke extraction box 17, and the purification box 21 can be connected to the inside of the smoke extraction box 17 through the smoke extraction pipe 2; the fixing plate 22 is fixedly connected to the inner wall of the purification box 21; the servo motor 23 is fixedly connected to the center of the fixing plate 22; the exhaust fan blade 24 is fixedly connected to the output end of the servo motor 23; the filter assembly is arranged on the inner wall of the purification box 21, and the filter assembly is used to filter and purify the extracted smoke When extracting the smoke and dust generated by cutting the photovoltaic panel, the servo motor 23 is fixed at the inner center of the purification box 21 by using the fixing plate 22, and the output end of the servo motor 23 drives the exhaust fan blades 24 to rotate quickly to extract air, and the smoke enters the interior of the smoke extraction box 17, and the smoke inside the smoke extraction box 17 is extracted into the interior of the purification box 21 through the smoke extraction pipe 2. The filter component filters and purifies the extracted smoke, and then it is discharged from the end of the purification box 21, which has the effect of extracting the smoke generated by the cutting. At the same time, relying on the continuous exhaust of the exhaust fan blades 24, the photovoltaic panel at the cutting location can be cooled down, reducing the thermal damage at the cutting location of the photovoltaic panel.

[0030] The filter assembly includes a sliding frame 3 and filter cotton 31; the sliding frame 3 is slidably connected to the inner wall of the purification box 21; the two filter cottons 31 are fixedly connected to the inner wall of the sliding frame 3; when the extracted flue gas and dust are purified, the exhaust fan blades 24 are used to extract the flue gas and dust into the interior of the purification box 21, and the flue gas and dust are filtered and purified when passing through the filter cotton 31 fixed on the sliding frame 3, and the purified flue gas is discharged upward, which plays a role in purifying the flue gas and dust. At the same time, relying on the sliding setting of the sliding frame 3, when a filter cotton 31 has been filtering and purifying for a long time and the purification effect becomes poor, another new filter cotton 31 installed on the sliding frame 3 can be pushed to the interior of the purification box 21, which plays a role in quickly replacing the filter cotton 31.

[0031] A return pipe 4 is fixedly connected to the top of the purification box 21; a diversion box 41 is fixedly connected to the end of the return pipe 4 away from the purification box 21; a plurality of diversion pipes 42 are fixedly connected to the bottom of the diversion box 41; a plurality of diversion pipes 42 are fixedly connected to an air box 43 at one end away from the diversion box 41, and the air box 43 is connected to the inside of the smoke extraction box 17; when extracting smoke and dust, the return pipe 4 is fixed to the top of the purification box 21, and the purified smoke inside the purification box 21 is sent into the inside of the return pipe 4, and then the gas is diverted through the diversion box 41, and is sent to the air box 43 for blowing out in conjunction with three diversion pipes 42, and is directly blown into the inside of the smoke extraction box 17 for circulation. By utilizing the flow of circulating wind, the output power of the servo motor 23 can be reduced, so that the wind at the smoke extraction box 17 can circulate, and the cooling effect on the photovoltaic panel at the cutting position can be enhanced.

[0032] The output end of the laser cutter 16 is externally connected to a plurality of spiral blades 5 for rotation; the plurality of spiral blades 5 are located inside the smoke extraction box 17; when the smoke and dust generated during cutting are extracted, the generated smoke and dust enter the inside of the smoke extraction box 17, and the smoke is extracted by the exhaust fan blades 24 for purification and then circulated, and the purified gas is blown out from the wind box 43 into the smoke extraction box 17, and the flow of gas can drive the plurality of spiral blades 5 outside the laser cutter 16 to rotate synchronously, and exhaust air by rotating the plurality of spiral blades 5, which can accelerate the flow of gas inside the smoke extraction box 17 and improve the efficiency of smoke and dust purification.

[0034] The fixing frame 13 is fixedly connected with a temporary storage box 7 on the outside away from the laser cutter 16; two temporary storage boxes 7 are arranged; when collecting the cut photovoltaic panels, the two temporary storage boxes 7 are fixed on the rear end outside of the fixing frame 13, and the No. 3 electric slider 61 can drive the adsorbed materials to slide into the temporary storage box 7 for temporary storage, so as to collect and temporarily store the cut photovoltaic panels. At the same time, in the process of cutting the photovoltaic panels, some photovoltaic panels are prone to fragmentation. The two temporary storage boxes 7 are used to classify the finished products and defective products, so as to classify and collect the photovoltaic panels.

[0035] A plurality of partition plates 8 are fixedly connected to the inner walls of the two temporary storage boxes 7; a plurality of air holes are provided on the plurality of partition plates 8; when collecting the cut photovoltaic panels, if multiple photovoltaic panels are stacked, it is easy to cause the photovoltaic panels to be damaged by stacking, and a plurality of partition plates 8 are evenly arrayed and fixed on the inner wall of the temporary storage box 7, and a photovoltaic panel is placed between every two partition plates 8, which plays the role of storing the photovoltaic panels in intervals, and residual heat is easy to remain after the photovoltaic panels are just cut, and relying on the plurality of air holes on the partition plates 8, the heat dissipation effect of the photovoltaic panels just cut can be improved.

[0036] like Figures 1 to 5As shown, a plurality of air holes 9 are provided on the inner wall at the top of the temporary storage box 7; a plurality of air ducts 91 are fixedly connected to the outside of the purification box 21, and one end of the air duct 91 away from the purification box 21 is fixedly connected to the temporary storage box 7, and the air holes 9 can be connected to the inside of the purification box 21 through the air duct 91; when the photovoltaic panel is cut, residual heat is likely to remain at the cut portion of the photovoltaic panel, and the long-term residual heat is likely to cause thermal damage to the photovoltaic panel, which will not only reduce the power generation efficiency, but also easily lead to safety hazards. The exhaust fan blades 24 are used for exhaust purification cycle, and part of the gas discharged from the top of the purification box 21 enters the interior of the air duct 91, and then the gas passes through the temporary storage box 7 from the air duct 91 to the plurality of air holes 9 and is blown out, and the gas can be blown onto the photovoltaic panel temporarily stored at the temporary storage box 7, thereby playing the role of air cooling the temporarily stored photovoltaic panel.

[0037] like Figures 1 to 4 As shown, the air outlet of the wind box 43 located inside the smoking box 17 is arranged to be tilted upward; the air outlet of the wind box 43 is arranged corresponding to the spiral blade 5; when the smoke inside the smoking box 17 is extracted and purified, the smoke is purified by the filter cotton 31 and then circulates along the reflux pipe 4 and is blown out from the air outlet of the wind box 43. The air outlet of the wind box 43 is arranged to be tilted, which can guide the circulating air to the spiral blade 5, thereby driving the spiral blade 5 to rotate faster and improving the flow purification speed of the smoke.

[0038] Working process: When cutting the photovoltaic panel, first place the photovoltaic panel to be cut on the end of the equipment base 1, and the fixing frame 13 cooperates with the two No. 1 electric sliders 12 to slide on the inner walls of the two No. 1 sliding grooves 11 respectively, which is used to drive the laser cutter 16 to move forward and backward. The No. 2 electric slider 14 drives the laser cutter 16 at the bottom of the connecting frame 15 to slide on the fixing frame 13, which is used to drive the laser cutter 16 to move left and right. The smoking box 17 moves to the upper position of the photovoltaic panel with the laser cutter 16, and the output of the laser cutter 16 The laser cutting starts from the end, and the generated smoke and dust can enter the inside of the smoke box 17 and then be extracted by the purification mechanism, so that the smoke and dust first enter the inside of the smoke box 17 and then enter the purification mechanism for purification, thereby reducing the accumulation of harmful gases and reducing the harm of harmful gases to the human body. At the same time, the smoke box 17 is used to shield the cutting position when cutting the photovoltaic panel, thereby reducing the collision of foreign objects with the output end of the laser cutter 16 and reducing the noise pollution generated during cutting. When the smoke and dust generated by cutting the photovoltaic panel are extracted, the fixed plate 2 is used to The servo motor 23 is fixed at the inner center of the purification box 21. The output end of the servo motor 23 drives the exhaust fan blade 24 to rotate quickly to extract air. The smoke enters the interior of the smoke extraction box 17. The smoke inside the smoke extraction box 17 is extracted to the interior of the purification box 21 through the smoke extraction pipe 2. The filter component filters and purifies the extracted smoke, and then it is discharged from the end of the purification box 21, which has the effect of extracting the smoke generated by cutting. At the same time, the exhaust fan blade 24 continuously extracts air, which can cool the photovoltaic panel at the cutting position and reduce the thermal damage of the photovoltaic panel at the cutting position. When the extracted smoke and dust are purified, the exhaust fan blades 24 are used to extract the smoke and dust into the purification box 21, and the smoke and dust are filtered and purified when passing through the filter cotton 31 fixed on the sliding frame 3, and the purified smoke is discharged upward, which plays a role in purifying the smoke and dust. At the same time, relying on the sliding setting of the sliding frame 3, when a filter cotton 31 has been filtered and purified for a long time and the purification effect becomes poor, another new filter cotton 31 installed on the sliding frame 3 can be pushed into the purification box 21, which plays a role in quickly replacing the filter cotton 31;

[0039] When extracting smoke and dust, the return pipe 4 is fixed on the top of the purification box 21, and the purified smoke inside the purification box 21 is sent to the inside of the return pipe 4, and then the gas is diverted through the diversion box 41, and is sent to the wind box 43 with three diversion pipes 42 for blowing out, and is directly blown into the smoke extraction box 17 for circulation. The flow of circulating wind can reduce the output power of the servo motor 23, so that the wind at the smoke extraction box 17 can circulate, and can enhance the cooling effect of the photovoltaic panel at the cutting position; when extracting smoke and dust generated during cutting, the generated smoke and dust enter the inside of the smoke extraction box 17, and the exhaust fan blades 24 are used to extract the smoke and purify it and circulate it. The purified gas is blown out from the wind box 43 into the smoke extraction box 17, and the flow of gas can drive the multiple spiral blades 5 outside the laser cutter 16 to rotate synchronously. The multiple spiral blades 5 rotate to extract air, which can accelerate the gas flow inside the smoke extraction box 17 and improve the efficiency of smoke and dust purification;

[0040] After the photovoltaic panel is cut, the No. 3 electric slider 61 drives the electric cylinder 62 to slide at the No. 2 sliding groove 6, and the output end of the electric cylinder 62 drives the vacuum suction cup 64 to extend downward to the cut photovoltaic panel. Then the vacuum pump 63 works with the vacuum suction cup 64 connected to the hose to vacuum absorb the photovoltaic panel, and the cut photovoltaic panel is sent to the storage point for temporary storage, which plays the role of collecting the photovoltaic panel.

[0041] When collecting the cut photovoltaic panels, two temporary storage boxes 7 are fixed on the rear end outside of the fixed frame 13, and the No. 3 electric slider 61 can drive the adsorbed materials to slide into the temporary storage box 7 for temporary storage, which plays a role in collecting and temporarily storing the cut photovoltaic panels. At the same time, in the process of cutting the photovoltaic panels, some photovoltaic panels are prone to fragmentation. Relying on the two temporary storage boxes 7 to classify and place finished products and defective products, it can play a role in classifying and collecting the photovoltaic panels; when collecting the cut photovoltaic panels, if multiple photovoltaic panels are stacked, it is easy to cause the photovoltaic panels to be damaged by stacking. A plurality of partition plates 8 are evenly arrayed and fixed on the inner wall of the temporary storage box 7, and a photovoltaic panel is placed between every two partition plates 8, which plays a role in collecting the photovoltaic panels. The photovoltaic panels are stored in intervals, and residual heat is likely to remain after the photovoltaic panels are just cut. Relying on the multiple air holes on the partition plate 8, the heat dissipation effect of the photovoltaic panels just cut can be improved; when the photovoltaic panels are cut, residual heat is likely to remain at the cut of the photovoltaic panels. The long-term residual heat is likely to cause thermal damage to the photovoltaic panels. Thermal damage will not only reduce the power generation efficiency, but also easily pose a safety hazard. The exhaust fan blades 24 are used for exhaust and purification circulation. Part of the gas discharged from the top of the purification box 21 enters the interior of the air duct 91, and then the gas passes through the temporary storage box 7 from the air duct 91 to the multiple air holes 9 and is blown out. The gas can be blown to the photovoltaic panels temporarily stored at the temporary storage box 7, which plays a role in air cooling the temporarily stored photovoltaic panels;

[0042] When the smoke inside the smoking box 17 is extracted and purified, the smoke is purified by the filter cotton 31 and then circulates along the reflux pipe 4 and is blown out from the air outlet of the wind box 43. The air outlet of the wind box 43 is inclined and can guide the circulating air to the spiral blade 5, thereby driving the spiral blade 5 to rotate faster and improving the flow purification speed of the smoke.
