[0028] As Figures 3-5 , Figure 7 , Figure 8 , Figure 12 and Figure 13As shown, the adjusting assembly 250 further comprises a positioning assembly 260, the positioning assembly 260 comprises a limiting groove 261 and a mounting plate 269, two limiting grooves 261 are symmetrically arranged in the middle of the inner top of the fixed rack 211 and the extension rack 212, it should be noted that the limiting groove 261 on the fixed rack 211 is longer than the limiting groove 261 on the extension rack 212, the fifth lead screw 263 is rotatably connected in the limiting groove 261 close to the inner part of the fixed rack 211, the fourth lead screw 262 is rotatably connected in the limiting groove 261 close to the inner part of the extension rack 212, the fourth lead screw 262 is provided with a driving piece at one end, the driving piece is mounted on the surface of the extension rack 212, the driving piece can be a motor, the fifth lead screw 263 is connected with the fourth lead screw 262 through an extension piece at one end adjacent to the fourth lead screw 262, the extension piece is generally composed of an extension rod and an extension groove, the second internal thread sliding block 264 is threadedly connected to the outer surfaces of the fourth lead screw 262 and the fifth lead screw 263, the fourth lead screw 262 and the second internal thread sliding block 264 are connected through a stop piece, and the mounting plate 269 is arranged at the bottom of the second internal thread sliding block 264. It can be understood that when the conveying piece 230 is conveying the aluminum profile sheet, the motor can be started to drive the fourth lead screw 262 to rotate in the limiting groove 261, the fourth lead screw 262 can drive the fifth lead screw 263 to rotate in the limiting groove 261 through the cooperation of the extension rod and the extension groove when the fourth lead screw 262 rotates, the fourth lead screw 262 and the fifth lead screw 263 can drive the second internal thread sliding block 264 on the surface to threadedly slide in the limiting groove 261 when the fourth lead screw 262 and the fifth lead screw 263 rotate, the second internal thread sliding block 264 can drive the two mounting plates 269 to move towards each other through the fixed rod 265 and the telescopic rod 2664 at the bottom when the second internal thread sliding block 264 threadedly slides. When the width of the rack 210 needs to be adjusted, the movement of the extension rack 212 can drive the fourth lead screw 262 to move, the fourth lead screw 262 can drive the extension rod to move when the fourth lead screw 262 moves, the extension rod can slide in the extension groove when the extension rod moves.

[0029] As shown in Figures 3-9 , Figure 12 and Figure 13 , the positioning assembly 260 further comprises a fixed rod 265 and a guide groove 268, a plurality of guide blocks 266 are equidistantly arranged at the bottom of the mounting plate 269, the surfaces of the fixed plate 221 and the moving plate 222 close to the upper part of the rack 210 are provided with the guide grooves 268 matched with the guide blocks 266, the guide plates 267 are fixedly arranged at the bottom of the guide blocks 266, the guide blocks 266 close to the top of the fixed rack 211 are connected with the second internal thread sliding block 264 through the fixed rod 265, and the guide blocks 266 close to the top of the extension rack 212 are connected with the second internal thread sliding block 264 through a lifting piece; It is conceivable that the two mounting plates 269 move towards each other, respectively driving the bottom guide block 266 to move towards each other, and the guide block 266 slides inside the guide groove 268, and the guide block 266 slides to drive the bottom guide plate 267 to move and fit on the surface of the lower fixed plate 221 and the moving plate 222. When the guide plate 267 moves to the side of the aluminum sheet, it can be positioned to avoid the aluminum sheet from shifting during conveying.

[0030] As shown in Figures 3-5 , Figure 7 , Figure 8 and Figure 12 , the rising piece includes a pushing groove 2661 and a telescopic rod 2664. The guide block 266 is provided with a pushing groove 2661 near the outer surface of the extension frame 212. A connecting plate 2662 is slidably connected inside the pushing groove 2661. An extrusion block 2663 is fixedly installed at one end of the connecting plate 2662. A drive piece is installed at the other end of the connecting plate 2662 through the inside of the extension frame 212. The drive piece is installed on the outside of the extension frame 212. The drive piece can be a gas cylinder. It is conceivable that when the aluminum sheet is welded, it needs to be unloaded. When the aluminum sheet is unloaded, the gas cylinder can be started to work. When the gas cylinder works, it can push the connecting plate 2662 to move. The connecting plate 2662 can slide inside the extension frame 212 and the pushing groove 2661. The connecting plate 2662 can drive the extrusion block 2663 to move. The extrusion block 2663 can be extruded on the top of the pushing groove 2661 through its own inclined surface. The pushing groove 2661 can push the guide block 266 to move vertically when it is extruded. The guide block 266 can extrude the telescopic rod 2664 when it moves vertically.

The outer surface of the inner threaded slide cylinder 2643 is provided with a tooth block 2644 through an elastic member. The elastic member is generally composed of an extrusion groove and a spring. An annular tooth groove 2642 is formed on the inner wall of the through hole 2641 and cooperates with the tooth block 2644. It should be explained that when the guide plate 267 on one side of the extension frame 212 is separated from the aluminum profile sheet, the motor can continue to work at this time, and the motor can drive the fourth lead screw 262 and the fifth lead screw 263 to continue to rotate. When the fourth lead screw 262 and the fifth lead screw 263 rotate, the second internally threaded sliding block 264 on the fourth lead screw 262 can threadedly slide in the limiting groove 261. When the second internally threaded sliding block 264 on the fourth lead screw 262 threadedly slides to the end of the limiting groove 261, the fourth lead screw 262 will continue to rotate. At this time, the fourth lead screw 262 rotates to drive the internally threaded sliding cylinder 2643 to rotate. The internally threaded sliding cylinder 2643 rotates to drive the toothed block 2644 to rotate. When the toothed block 2644 rotates, the annular tooth groove 2642 will extrude the inclined surface of the toothed block 2644. When the toothed block 2644 is extruded, it will slide into the extrusion groove. The toothed block 2644 slides to compress the spring. When the toothed block 2644 is completely extruded into the extrusion groove, the internally threaded sliding cylinder 2643 will continue to rotate, so that when the second internally threaded sliding block 264 threadedly slides to the end of the limiting groove 261, it will not affect the continuous rotation of the fourth lead screw 262. When the second internally threaded sliding block 264 on the fifth lead screw 263 threadedly slides, the parts can cooperate to drive the guide plate 267 to move. When the guide plate 267 moves, it will push one side of the aluminum profile sheet. It should be explained that the route of the guide plate 267 can avoid the conveying part 230. When the aluminum profile sheet is pushed, it can be unloaded through the discharge port 240.

[0032] As shown in Figures 1-3 , Figures 10-12 and Figure 14 , the welding mechanism 300 includes a mounting frame 310 and a through slot 360. The mounting frame 310 is arranged between the two frames 210. The left side of the mounting frame 310 is movably connected with one of the hinges 2513, and the right side of the mounting frame 310 is fixedly connected with another hinge 2513. The top of the mounting frame 310 is provided with a horizontal moving part 320. The bottom of the horizontal moving part 320 is provided with a welding head 330 through an extension part. The extension part can be a pneumatic cylinder. The bottom of the horizontal moving part 320 close to the welding head 330 is provided with a positioning plate 340. The bottom of the positioning plate 340 is movably connected with the mounting frame 310. The two sides of the positioning plate 340 are provided with touch sensors 350. The front of the mounting frame 310 is provided with a through slot 360. It is worth noting that when the two aluminum profile sheets are conveyed to the two sides of the positioning plate 340, they will touch the touch sensor 350, which can identify the position where the two aluminum profile sheets touch and send instructions to the horizontal moving piece 320. After receiving the instructions, the horizontal moving piece 320 works, and when the horizontal moving piece 320 works, it drives the positioning plate 340 to move with the cylinder and the welding head 330. When the positioning plate 340 moves, it slides with the mounting frame 310. When the positioning plate 340 slides, it gradually separates from the two aluminum profile sheets. When the cylinder and the welding head 330 move to the designated position, the cylinder works to push the welding head 330 to move. When the welding head 330 moves to the position between the two aluminum profile sheets, it can perform welding, so that the welding head 330 can perform precise welding when the two aluminum profile sheets are not the same width.

[0033] An aluminum profile sheet welding method using the aluminum profile sheet welding device described above, the method comprising the following steps: S1, before use, the width of the rack 210 and the support plate 220 needs to be adjusted according to the width of the two aluminum profile sheets; S2, after the width adjustment of the rack 210 and the support plate 220 is completed, the aluminum profile sheets are placed between the upper and lower support plates 220, and the support plates 220 are used to clamp the aluminum profile sheets; S3, after the aluminum profile sheets are clamped, the conveying piece 230 works to convey, and at the same time, the positioning assembly 260 can position the aluminum profile sheets through the guide plate 267 to avoid deviation of the aluminum profile sheets during conveying; S4, when the aluminum profile sheets are conveyed to the side of the touch sensor 350, the touch sensor 350 can position the two aluminum profile sheets, and after the aluminum profile sheets are positioned, the position adjusting structure 253 works to adjust the position of the smaller aluminum profile sheet, and also can adjust the adjacent angle of the two aluminum profile sheets according to the angle adjusting structure 251; S5, after the position and angle adjustment of the aluminum profile sheets are completed, the horizontal moving piece 320 works to drive the welding head 330 to weld the adjacent positions of the two aluminum profile sheets; S6, after the two aluminum profile sheets are welded, the positioning assembly 260 works to push the aluminum profile sheets out through the discharge port 240.
