When in use, by horizontally placing the photovoltaic panel on the bearing bar 3, the cutting position of the laser cutter 2 is adjusted by using the first direct drive mechanism 5, then the laser cutter 2 and a dust extraction mechanism 10 are driven downward by the second lifting mechanism 9, and at the same time the other dust extraction mechanism 10 is driven upward by the first lifting mechanism 7, and then the laser cutter 2 and a dust extraction mechanism 10 are driven to move linearly by the second direct drive mechanism 6 and the other dust extraction mechanism 10 is driven to move linearly by the third direct drive mechanism 8, so as to realize the cutting process of the photovoltaic panel and the dust extraction process above and below the cutting position of the photovoltaic panel, which not only ensures the cutting efficiency of the photovoltaic panel, but also effectively avoids the pollution of the workshop environment by the dust and smoke generated during laser cutting.

[0040] Among them, such as Figure 3-4As shown in the figure, the first direct drive mechanism 5 includes a pair of first guide rods 501 arranged side by side between the two side support frames 4, and both ends of each first guide rod 501 are bolted to the upper edges of the two side support frames 4 respectively; guide blocks 502 are slidably sleeved on both first guide rods 501; a first screw rod 503 is horizontally arranged between the two first guide rods 501; both ends of the first screw rod 503 are rotatably connected to the upper edges of the two side support frames 4 respectively; one end of the first screw rod 503 is coaxially fixed to the output shaft of a first motor 504; the first motor 504 is horizontally bolted to one side support frame 4; a first transmission block 505 is threadedly connected to the first screw rod 503; the first transmission block 505 is connected to the two guide blocks 502 through a mounting plate strip 506 perpendicular to the bearing strip 3.

When it is necessary to move the other dust extraction mechanism 10 between any two load - bearing bars 3, the third motor 706 drives the second guide rod 602 to rotate through the fourth pulley 705 and the third pulley 704, prompting the second guide rod 602 to drive the two drive shafts 701 to rotate synchronously through the second bevel gear 708 and the first bevel gear 707, realizing the synchronous up - and - down movement of the two lifting cylinders 702 driving the two transmission seats 703, thereby realizing the position adjustment of the other dust extraction mechanism 10; when it is necessary to adjust the cutting position of the photovoltaic panel, the first lifting mechanism 7 first moves the other dust extraction mechanism 10 out from between any two load - bearing bars 3 and makes the other dust extraction mechanism 10 be located below the load - bearing bars 3, and then drives the laser cutter 2 and the two dust extraction mechanisms 10 to move linearly through the first direct drive mechanism 5, realizing the adjustment of the cutting position of the photovoltaic panel, avoiding problems such as interference between the dust extraction mechanism 10 and the load - bearing bars 3.

[0051] Among them, as Figure 14 shown, a cooling chamber 1103 is provided inside the other end of each of the two mounting columns 1101; a coolant delivery pipe 1104 is connected to each of the two cooling chambers 1103; one coolant delivery pipe 1104 is used for inputting coolant, and the other coolant delivery pipe 1104 is used for outputting coolant; both end faces of the roller 1102 have delivery ports 1105; the two delivery ports 1105 are respectively rotatably connected to the opposite inner side walls of the two cooling chambers 1103; the inner cavity of the roller 1102 is communicated with the cooling chamber 1103 through the delivery ports 1105. During use, coolant (the coolant is cold water) is delivered to the inner cavity of the roller 1102 through one coolant delivery pipe 1104 via one cooling chamber 1103, and the coolant in the inner cavity of the roller 1102 is output through the other coolant delivery pipe 1104 via the other cooling chamber 1103, so that the surface of the roller 1102 is in a low-temperature state, thereby enabling the roller 1102 to flatten and cool the cutting edge of the photovoltaic panel at the same time, effectively improving the flatness of the cutting edge of the photovoltaic panel.

[0052] In addition, as Figure 4-6 and Figure 8-13As shown in the figure, the dust extraction mechanism 10 above the bearing strip 3 is connected to the lifting strip 902 through the first rotation mechanism 12; the dust extraction mechanism 10 below the bearing strip 3 is connected to the third transmission block 802 through the second rotation mechanism 13; the first rotation mechanism 12 includes a pair of first racks 1201 horizontally bolted to the opposite side surfaces of the mounting strip 506 and a first internal gear ring 1202 horizontally arranged below the lifting strip 902; both first racks 1201 are arranged parallel to the first guide rod 501, and the two first racks 1201 are respectively arranged at the two end portions of the mounting strip 506; a first annular groove 1203 is formed on the circumferential outer surface of the first internal gear ring 1202; a pair of first limit blocks 1204 are slidably connected in the first annular groove 1203; both first limit blocks 1204 are bolted to the lower surface of the lifting strip 902; a pair of first rotating shafts 1205 are vertically arranged inside the first internal gear ring 1202; the two first rotating shafts 1205 are respectively vertically rotatably connected to the two end portions of the lifting strip 902; the upper ends of the two first rotating shafts 1205 are key-connected with conventional first one-way gears 1206 in the art; the two first one-way gears 1206 can respectively mesh with the two first racks 1201; the lower ends of the two first rotating shafts 1205 are key-connected with first transmission gears 1207; the two first transmission gears 1207 are both meshed with the first internal gear ring 1202; the two negative pressure boxes 1001 above the bearing strip 3 are both bolted to the lower surface of the first internal gear ring 1202; the second rotation mechanism 13 includes a pair of second racks 1301 horizontally bolted to the two positioning seats 601 and a connecting strip 1308 horizontally bolted to the upper end of the third transmission block 802; both second racks 1301 are arranged parallel to the second guide rod 602, and the two second racks 1301 are respectively arranged on the opposite sides of the second guide rod 602; the length direction of the connecting strip 1308 is perpendicular to the length direction of the third guide rod 801; a second internal gear ring 1302 is horizontally arranged above the connecting strip 1308; a second annular groove 1303 is formed on the circumferential outer surface of the second internal gear ring 1302; a pair of second limit blocks 1304 are slidably connected in the second annular groove 1303; both second limit blocks 1304 are bolted to the upper surface of the connecting strip 1308; a pair of second rotating shafts 1305 are vertically arranged inside the second internal gear ring 1302; the two second rotating shafts 1305 are respectively rotatably connected to the two end portions of the connecting strip 1308; the lower ends of the two second rotating shafts 1305 are key-connected with conventional second one-way gears 1306 in the art; the two second one-way gears 1306 can respectively mesh with the two second racks 1301; the upper ends of the two second rotating shafts 1305 are key-connected with second transmission gears 1307; the two second transmission gears 1307 are both meshed with the second internal gear ring 1302; the two negative pressure boxes 1001 below the bearing strip 3 are both bolted to the upper surface of the second internal gear ring 1302.In use, after the laser cutter 2 completes one cut of the photovoltaic panel, the second screw 604 continues to drive the laser cutter 2 towards one end of the second screw 604, causing a first one-way gear 1206 to mesh with a first rack 1201, and the first one-way gear 1206 rolls on the first rack 1201, enabling the first one-way gear 1206 to drive two negative pressure boxes 1001 located above the bearing bar 3 to rotate horizontally synchronously via a first rotating shaft 1205, a first transmission gear 1207, and a first internal gear ring 1202. At the same time, a second one-way gear 1306 meshes with a second rack 1301, and the second one-way gear 1306 rolls on the second rack 1301, enabling the second one-way gear 1306 to drive two negative pressure boxes 1001 located below the bearing bar 3 to rotate horizontally synchronously via a second rotating shaft 1305, a second transmission gear 1307, and a second internal gear ring 1302. When the negative pressure box 1001 rotates horizontally by 180°, the second screw 604 stops driving the laser cutter 2 towards one end of the second screw 604. Then, after the cutting position of the photovoltaic panel is adjusted by the first direct drive mechanism 5, the second screw 604 drives the laser cutter 2 towards the other end of the second screw 604. At this time, although the first one-way gear 1206 meshes with the first rack 1201 and the second one-way gear 1306 meshes with the second rack 1301, the first one-way gear 1206 does not drive the first rotating shaft 1205 to rotate and the second one-way gear 1306 does not drive the second rotating shaft 1305 to rotate either, that is, the negative pressure box 1001 does not rotate, thereby ensuring that the roller 1102 is always behind the laser cutter 2 and guaranteeing the working effect of the roller 1102. When another first one-way gear 1206 meshes with another first rack 1201 and another second one-way gear 1306 meshes with another second rack 1301, the adjustment state of the negative pressure box 1001 is the same as above and will not be elaborated further.
