Description

Technical Field

[0002] The AI ​​intelligent laser cutting assembly line is an important technology in modern manufacturing. It combines advanced laser cutting technology and artificial intelligence (AI) technology to improve production efficiency, reduce costs and enhance product quality. In existing technologies, AI intelligent laser cutting generally completes material removal after cutting, which enables rapid replacement of plates, thereby achieving rapid and continuous production and reducing downtime. Although laser cutting has high cutting accuracy, for some parts with complex shapes or large sizes, the cutting material and the plate are prone to jamming when they are separated, requiring timely manual intervention to assist in material removal, which seriously affects production efficiency. At the same time, the cutting material that has not been separated will likely be separated during transportation, causing unnecessary damage.

[0041] See also Figures 1-8 In an embodiment of the present invention, an AI intelligent laser cutting production line includes:

[0042] The feeding and loading frame 1 has a feeding roller group 11 and a discharging roller group on both sides thereof. The feeding roller group 11 and the discharging roller group are installed at the same horizontal height position, and are used to transport the sheets to be processed one by one;

[0043] The inner conveyor belt 12 is horizontally installed in the feeding frame 1 and is located between the feeding roller group 11 and the discharging roller group;

[0044] A cutting machine platform is provided outside the feeding frame 1 and close to the discharge roller group. A laser cutting mechanism 2 is installed on the cutting machine platform. The laser cutting mechanism 2 cuts the sheet metal along a predetermined route.

[0045] The transfer roller 13 is distributed in the cutting machine and is used to transport the sheet metal that has completed the cutting process to the outside;

[0046] The demoulding table 3 is arranged on one side of the cutting machine table. A material cutting device 31 is installed on the demoulding table 3. The laser cutting mechanism 2 adopts multiple sets of leaping actions in the sheet cutting to form a number of incomplete cutting points in the cutting path of the sheet, so that the workpiece and the sheet are not demoulded; the material cutting device 31 uses a steel knife to perform subsequent cutting on each incomplete cutting point, so as to achieve complete separation of the workpiece and the sheet. That is to say, the laser cutting mechanism 2 can perform laser cutting on the sheet on the cutting machine, and there are multiple incomplete cutting points between the workpiece and the sheet after cutting, so that a certain connectivity is achieved between the workpiece and the sheet, avoiding the jamming phenomenon caused by direct stripping.

[0047] In this embodiment, the laser cutting mechanism 2 includes:

[0048] The base 21 has a plurality of sliders 22 mounted on its lower end surface;

[0049] A three-dimensional driving frame is mounted on the cutting machine table. A guide rail 23 is horizontally mounted on the three-dimensional driving frame. The slider 22 is slidably connected to the guide rail 23.

[0050] A laser cutter 5 is vertically arranged below the machine base 21;

[0051] The calibration unit 4 is arranged in the machine base 21, and the laser cutter 5 is installed on the calibration unit 4. The calibration unit 4 is used to perform spatial positioning adjustment on the laser cutter 5 so that the laser cutter 5 reaches a specific angle orientation during the cutting work, thereby facilitating the laser cutter 5 to perform corresponding cutting actions or leaping actions.

[0052] As a preferred embodiment, the calibration unit 4 includes:

[0053] A central shaft 41 is vertically rotatably connected to the base 21;

[0054] The transmission gear is fixed above the central shaft 41. A motor 42 is installed in the base 21. The output end of the motor 42 is connected to the transmission gear through a tooth chain.

[0055] A fixing frame 43 is fixed below the central axis 41;

[0056] The guide plate 44 has an arc-shaped cross section. The center of the guide plate 44 is fixed below the fixing frame 43 . The center position of the guide plate 44 is rotatably connected to the limiting sleeve 45 . The end of the laser cutter 5 is deeply fixed in the limiting sleeve 45 .

[0057] In this embodiment, the rotation angle of the central axis 41 is 360°; so that the end surface of the guide plate 44 can be aligned with the cutting track during the leaping action, so that the laser cutter 5 can perform angle calibration along the cutting track;

[0058] A guide groove 49 is formed in the guide plate 44, and a roller 46 is provided outside the laser cutter 5. The roller 46 slides along the guide groove 49 to deflect the laser cutter 5. The deflection angle range of the laser cutter 5 is between -30° and 30°.

[0059] A connecting frame is fixed on the guide plate 44, and a bracket plate 47 is rotatably connected to the connecting frame, and a slide groove 410 is provided in the bracket plate 47; and an axle pin 46 is vertically fixed to the outside of the laser cutter 5, and the axle pin 46 is slidably connected in the slide groove 410; an electric telescopic rod 48 is rotatably connected to the connecting frame, and one end of the electric telescopic rod 48 is hinged to the bracket plate 47, that is, the electric telescopic rod 48 can drive the laser cutter 5 to slide along the guide groove under the corresponding telescopic adjustment, thereby changing the cutting angle of the laser cutter 5, so that the sheet material is obliquely cut when the cutting operation is performed on the incomplete cutting point in the sheet material cutting route. Compared with vertical sheet material cutting, it expands the depth of the laser line cutting into the sheet material, thereby causing the laser cutter 5 to form an incomplete cutting of the sheet material.

[0060] In this embodiment, a laser channel 51 is provided in the middle of the laser cutter 5, and a nozzle 6 is fixed below the laser cutter 5. A built-in cone head 52 is coaxially provided in the nozzle. The built-in cone head 52 and the inner wall of the laser cutter 5 form an airflow ring cavity 53.

[0061] The laser cutter 5 is externally connected to an air guide mechanism 56 , which is sealed and connected to the air flow annular cavity 53 and is used to transport laser auxiliary gas into the air flow annular cavity 56 ;

[0062] Two air holes 61 are symmetrically provided above the nozzle 6 , an air channel 62 is also provided inside the nozzle 6 , the air holes 61 are connected to the air channel 62 , and a nozzle 63 is provided at each air channel 62 below the nozzle 6 .

[0063] In this embodiment, a block 55 is symmetrically and slidably connected in the air flow annular cavity 53. Each of the block 55 can partially block the air hole 61 above the nozzle 6. A spring is connected to the block 55, and one end of the spring abuts against the built-in cone head 52. Therefore, in the absence of external force, the spring force enables the block 55 to slide to a position away from the center of the laser cutter 5, so that each air hole 61 is not fully opened. However, during normal laser cutting perpendicular to the sheet material, each air hole 61 can pass the required laser auxiliary gas.

[0064] The laser cutter 5 is slidably connected with a guide head 54, one end of which is connected to a block 55, and a block is provided on the guide disk of the calibration unit 4, so that the laser cutter 5 is pressed against the guide head 54 on the deflected side by the block during the angle adjustment of the calibration unit 4, thereby changing the ventilation volume of the two air holes 61. For example, in the early stage of the leap forward action, the laser cutter 5 needs to be deflected counterclockwise along the end face of the guide disk 44. At this time, the guide head 54 on the left side of the laser cutter 5 can gradually contact and press against the block on the left side of the guide disk 44. As a result, the block 55 on the left side slides toward the center of the laser cutter 5, and the corresponding air hole 61 gradually expands and fully opens, while the air hole 61 on the other side is fully opened and remains unchanged, and the laser auxiliary gas quickly enters the nozzles 63 through the air hole 61 on the left and is ejected, so that the laser auxiliary gas accumulates on the left side, and the auxiliary gas on the right side is relatively weak, fundamentally controlling the flow distribution of the laser auxiliary gas source, thereby reducing the laser cutting intensity of the laser cutter 5 on the sheet material, thereby enabling incomplete cutting of the sheet material.

[0065] As a preferred embodiment, the nozzles 63 are provided in plurality and arranged in an isosceles triangle.

[0066] In this embodiment, the leaping action of the laser cutting mechanism 2 is that the laser cutter 5 gradually approaches the position of the predetermined incomplete cutting point. When it reaches the front distance of 5 mm from the incomplete cutting point, the center axis 41 in the calibration unit 4 makes the end face of the guide disk 44 parallel to the cutting track under rotation adjustment. At this time, the calibration unit 4 deflects the laser cutter 5 counterclockwise along the guide disk 44. While the laser cutting mechanism 2 continues to move along the track, the laser cutter 5 is reset clockwise along the guide disk 44. When it is in the middle of the incomplete cutting point, the laser cutter 5 is in a vertical state. While continuing to cut, the laser cutter 5 is deflected clockwise along the guide disk 44 and deflected and reset at a position 5 mm behind the incomplete cutting point.

[0067] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
