The upper pressure plate 63 is fixed on the top of the fixed side plate 611 and the movable side plate 621, and is located above the conveyor belt.

[0029] The conveying device is installed on the top of the frame and is located below the laser cutter. After the cutting jig is positioned and lifted, the laser cutter performs cutting. The width adjustment device 7 realizes the width adjustment of the conveying device, and then adapts to different cutting jigs. At the same time, the positioning device and the side push device 5 realize the positioning of the cutting jig, and then the lifting device 1 and the upper pressure plate 63 realize the fixing of the cutting jig for laser cutting, which effectively ensures the cutting quality and improves the cutting accuracy.

[0030] like Figures 1 to 5 As shown, the width adjustment device 7 includes an adjustment motor 71, an active screw rod 72 and an active nut 73. The adjustment motor 71 is installed on the top of the frame and is located on one side of the movable conveyor line 62.

[0031] like Figure 3 and Figure 6 As shown, the side push device 5 includes a side push seat 52, a side push plate 51 and a side push cylinder 53. The side push seat 52 is installed on the movable side plate 621 of the movable conveyor line 62. The top of the movable side plate 621 is provided with a plurality of push grooves 6211. The side push plate 51 is slidably installed on the bottom of the side push seat 52 through a linear guide pair.

The side push rods 511 are movably inserted into the push grooves 6211 and are arranged opposite to the fixed side plate 611 of the fixed conveyor line 61, and are used to press the cutting jig onto the fixed side plate 611 to achieve the positioning of the cutting jig in the width direction. The push grooves 6211 and the side push rods 511 avoid forming a large gap at the top of the movable side plate 621 to prevent the movement of the cutting jig from being blocked.

[0032] like Figures 7 to 10 As shown, the lifting device 1 includes a lifting base plate 1, a lifting plate 33, a moving plate 35, a lifting roller 42, a connecting rod 49, a lifting cylinder 47 and a driving plate 41. The lifting base plate 1 is mounted on the frame, and the lifting linear guide rail 31 is fixed on the lifting plate 33, and two lifting linear guide rails 31 are symmetrically arranged, and the lifting linear guide rails 31 are arranged vertically; the lifting slider 32 is slidably installed on the lifting linear guide rail 31 and connected to the lifting base plate 1, and the lifting plate 33 is lifted and lowered in the vertical direction, and the moving plate 35 is fixed on the top of the lifting plate 33. The cam 43 is a right triangle, and the right angle of the cam 43 is rotatably mounted on the lifting base plate 1 through the first rotating shaft 44, one corner of the cam 43 is rotatably connected to the connecting rod 49 through the second rotating shaft 45, and the other corner of the cam 43 is movably against the bottom of the lifting plate 33, and the cam 43 is symmetrically arranged with two, and is respectively located at the two ends of the bottom of the lifting base plate 1 and at the two ends of the lifting plate 33. The tail of the lifting cylinder 47 is rotatably mounted on the frame, and the lifting cylinder 47 is horizontally arranged. The end of the piston rod of the lifting cylinder 47 is connected to one end of the connecting rod 49 through a key bearing 46 .

[0033] When the piston rod of the lifting cylinder 47 extends, the connecting rod 49 drives the two cams 43 to flip upward, the cams 43 lift the lifting plate 33, and the lifting plate 33 drives the moving plate 35 to rise. When the piston rod of the lifting cylinder 47 retracts, the cams 43 are reset, and the lifting plate 33 and the moving plate 35 descend to their original positions under the action of gravity.

[0034] Since the lifting cylinder 47 is arranged on the side, the height of the lifting device can be greatly reduced, the height of the conveying device is reduced, and the space utilization rate is improved.

[0035] The two cams 43 simultaneously lift the lifting plate 33 from both ends of the lifting plate 33, which can effectively ensure that the lifting heights of both ends of the lifting plate 33 are consistent, improve the lifting positioning accuracy, and reduce the error caused by the deformation of the longer moving plate 35.

[0036] The cam 43 and the lifting plate 33 can be driven by the lifting roller 42, and the lifting roller 42 converts the sliding friction between the cam 43 and the lifting plate 33 into rolling friction, making the movement smoother and more reliable. The lifting roller 42 and the second rotating shaft 45 are respectively located on both sides of the first rotating shaft 44, and form a triangle.

[0037] In order to improve the reliability of lifting, a driving plate 41 is further included. The driving plate 41 is fixed to the bottom of the lifting plate 33. A driving groove 411 is provided on the driving plate 41. The driving groove 411 is a waist-shaped groove and is arranged in the horizontal direction. The lifting roller 42 is movably inserted in the driving groove 411. The lifting roller 42 and the driving groove 411 can drive the lifting plate 33 and the moving plate 35 to reset, prevent the lifting plate 33 and the moving plate 35 from failing to descend autonomously, and ensure reliable lifting.

[0038] Lifting grooves 331 are symmetrically provided at both ends of the lifting plate 33 , and the cam 43 and the lifting roller 42 are both located in the lifting grooves 331 . The lifting grooves 331 can further reduce the height of the lifting device, making the structure more compact.

[0039] The overall height of the lifting device is small, and it can effectively accommodate small-width and long-sized products in a relatively limited space.

[0040] The positioning device includes a positioning sensor 82 and a positioning cylinder 83. The positioning sensor 82 is installed on the lifting plate 33 of the jacking device 1 of the fixed conveyor line 61 through a sensor seat to detect whether there is a cutting jig above. The positioning cylinder 83 is installed at the discharge end of the movable conveyor line 62. When the positioning sensor 82 detects the cutting jig, the piston rod of the positioning cylinder 83 extends, and the positioning cylinder 83 blocks the cutting jig, and then the fixed conveyor line 61 and the movable conveyor line 62 stop. The positioning sensor 82 can be a photoelectric sensor or a proximity switch.

[0041] During operation, first adjust the spacing between the movable conveyor line 62 and the fixed conveyor line 61 according to the width of the cutting jig by adjusting the motor 71. When the spacing is adjusted to the right position, start the movable conveyor line 62 and the fixed conveyor line 61, and the cutting jig enters the top of the lifting device 1. When the positioning sensor 82 detects the cutting jig, the piston rod of the positioning cylinder 83 extends, and the cutting jig is blocked by the positioning cylinder 83. Then the fixed conveyor line 61 and the movable conveyor line 62 stop, and then the side push cylinder 53 is started, and the side push plate 51 presses the cutting jig against the fixed side plate 611 of the fixed conveyor line 61, and then the side push cylinder 53 drives the side push plate 51 to retract, and then the lifting cylinder 47 is started, the movable plate 35 rises, and presses the cutting jig under the upper pressure plate 63 to realize the positioning of the cutting jig, and then the laser cutter is started for laser cutting. When the laser cutting is completed, the lifting cylinder 47 drives the movable plate 35 and the cutting jig to descend, and the cutting jig returns to the conveyor belt. The piston rod of the positioning cylinder 83 retracts, and then the fixed conveyor line 61 and the movable conveyor line 62 are started to send out the cutting jig.
