Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0041] As mentioned in the background art of this application, through research, it is found that existing aluminum plate cutting equipment usually adopts laser cutting. However, during local cutting, there are certain defects such as insufficient cutting accuracy, low cutting material processing efficiency, and lack of detection ability.

[0042] To solve the above defects, this application discloses a local thermal cutting equipment and a thermal cutting method for aluminum plate processing, which can not only improve the cutting accuracy, but also improve the cutting material processing efficiency, and effectively detect the quality and shape of the cutting surface in real time.

[0043] The following will introduce in detail how the solution of this application solves the above technical problems in combination with the accompanying drawings.

[0044] Please refer to Figures 1 to 8 , in the embodiment of the present invention, a local thermal cutting equipment for aluminum plate processing includes a box body 1. A cutting table 2 is fixedly connected to the top end surface of the box body 1, and a stepped plate placing groove 3 is opened on the top end surface of the cutting table 2. A laser cutting mechanism is arranged on the outer side surface of the cutting table 2. A chamber 8 is opened inside the box body 1. A material receiving and detecting component is arranged at the middle position inside the chamber 8. A shielding component is arranged above the material receiving and detecting component, and a material transfer mechanism is arranged below the material receiving and detecting component. A notch 38 matching the stepped plate placing groove 3 is opened on the top end surface of the box body 1. This application can not only improve the cutting accuracy, but also improve the cutting material processing efficiency, and effectively detect the quality and shape of the cutting surface in real time.

[0045] In this embodiment, the material receiving and detecting component specifically includes: two first Y-axis movement modules 9 fixedly arranged in parallel on the inner wall of the chamber 8. A first X-axis movement module 10 is arranged between the two first Y-axis movement modules 9. A first Z-axis movement module 11 is arranged on the outer side surface of the first X-axis movement module 10. A flipping material receiving mechanism is fixedly connected to one side surface of the first Z-axis movement module 11. A horizontal camera 26 is embedded on the inner wall of the chamber 8 on one side of the flipping material receiving mechanism. A vertical camera 25 is fixedly connected to the position near the upper part of one side inner wall of the chamber 8, and the vertical camera 25 is located below the shielding component. By setting the material receiving and detecting component in this application, it can hold the area to be cut during thermal cutting, avoid the cutting surface being uneven due to material dropping deviation during cutting, which affects the product quality, and thus improve the final cutting accuracy.

[0046] In this embodiment, the flipping and material receiving mechanism specifically includes: a rotating base 12 fixed on the first Z-axis motion module 11. A rotating groove 13 is formed on the top end surface of the rotating base 12, and a rotating block 14 is rotatably connected inside the rotating groove 13. A rotating motor 21 is embedded in the top end surface of the rotating block 14, and a strip-shaped plate 16 is fixedly connected to the output shaft of the rotating motor 21. Two L-shaped support plates 18 are symmetrically and fixedly connected to both sides of the top end surface of the strip-shaped plate 16, and a cylinder 19 is fixedly connected to the inner side surface of the L-shaped support plate 18. The top output shaft of the cylinder 19 penetrates through the L-shaped support plate 18 and is fixedly connected to a negative pressure suction head 20. Two flipping motors 15 are symmetrically and fixedly connected to both side surfaces of the rotating base 12, and the output shaft of the flipping motor 15 is fixedly connected to the rotating block 14. The flipping and material receiving mechanism can directly receive the waste materials or finished products when they are cut off, avoiding damage caused by dropping and bumping, and thus ensuring the recycling value of the waste materials or finished products. In addition, the flipping and material receiving mechanism can cooperate with the horizontal camera 26 and the vertical camera 25 to detect the quality and shape of the cutting surface in real time, and then promptly remove the defective products.

[0047] In this embodiment, fill light lamps 17 are embedded at positions near the edges on both sides of the top end surface of the strip-shaped plate 16. The setting of the fill light lamps 17 can provide supplementary lighting during the process of detecting the quality and shape of the cutting surface in real time, improving the detection effect.

[0048] In this embodiment, the material transfer mechanism specifically includes: a concave plate 22 fixed below the interior of the chamber 8. One end of the concave plate 22 penetrates through the chamber 8 and extends to the outside of the box body 1, and a rubber conveyor belt 23 is arranged inside the groove of the concave plate 22. Two groups of parallel slots 24 are formed on the outer side surface of the rubber conveyor belt 23, and the number of slots 24 in each group is several. The concave plate 22 is arranged opposite to the first Z-axis motion module 11. Through the arranged material transfer mechanism in this application, the waste materials or finished products after cutting do not need to be manually sorted, which saves time and is not easy to cause material waste.

[0049] In this embodiment, the shielding assembly specifically includes: two horizontally linear guide rails 34 symmetrically fixed above the inner walls on both sides of the chamber 8. Two juxtaposed horizontally linear motors 35 are movably connected to the outer sides of the horizontally linear guide rails 34. A strip-shaped docking plate 36 is fixedly connected between the two opposite horizontally linear motors 35. Storage boxes 29 are fixedly connected to the top ends of both side faces of the box body 1. A storage cavity 31 is formed inside the storage box 29. A roller body 32 is rotatably connected inside the storage cavity 31. A shielding cloth 33 is wound around the outer part of the roller body 32. One end of the shielding cloth 33 penetrates through the inner wall of the chamber 8 and is connected to the corresponding strip-shaped docking plate 36. A stepping motor 30 is fixedly connected to the position of the storage box 29 corresponding to the roller body 32 on one side face, and the output shaft of the stepping motor 30 is fixedly connected to the roller body 32. Through the provided shielding assembly in this application, when the quality and shape of the cutting surface are detected in real time, a relatively independent sealed space can be provided for it, reducing the interference of external light from above and improving the detection accuracy.

[0050] In this embodiment, strong magnets 37 are embedded in the opposite faces of the two strip-shaped docking plates 36. The setting of the strong magnets 37 can improve the connection tightness of the two strip-shaped docking plates 36.

[0051] In this embodiment, a discharge chute 27 is formed at the bottom end of one side face of the box body 1. A switch door 28 is movably connected inside the discharge chute 27. The height of the bottom end face of the chamber 8 gradually decreases from the side far away from the discharge chute 27 to the side close to the discharge chute 27. When the residues of laser cutting fall onto the bottom end face of the chamber 8 along the notch 38, they move towards the discharge chute 27 under the action of their own gravity. Subsequently, the staff opens the switch door 28 to clean and recycle the residues. This setting facilitates the smooth flow of the residues of laser cutting from the discharge chute 27.

[0052] In this embodiment, the laser cutting mechanism specifically includes: two second X-axis motion modules 4 symmetrically arranged on both side faces of the cutting table 2. A second Y-axis motion module 5 is arranged between the two second X-axis motion modules 4. A second Z-axis motion module 6 is arranged on the outer side face of the second Y-axis motion module 5. A laser cutting head 7 is fixedly connected to one side face of the second Z-axis motion module 6. The laser cutting mechanism can perform rapid and efficient thermal cutting on the aluminum plate.

[0053] This application also discloses a local thermal cutting method for aluminum plate processing, which uses a local thermal cutting device for aluminum plate processing and includes the following steps: placing the aluminum plate to be processed in the stepped plate placing groove 3, and then transferring the material receiving and detecting assembly to directly below the area to be cut; supporting the area to be cut through the material receiving and detecting assembly, and running the laser cutting mechanism to perform thermal cutting processing on the area to be cut; after the thermal cutting is completed, receiving and transferring the cut material through the material receiving and detecting assembly, and detecting the cutting surface and shape of the cut material; separating and sending out the qualified cut material and the unqualified cut material through the material transfer mechanism according to the detection results.

[0054] The working principle of the present invention is as follows: When in use, first, place the aluminum plate to be cut in the stepped plate placing groove 3. Subsequently, through the first Y-axis movement module 9, the first X-axis movement module 10 and the first Z-axis movement module 11, transfer the flipping and material receiving mechanism of the material receiving and detecting assembly to directly below the area to be cut. Immediately afterwards, the cylinder 19 of the flipping and material receiving mechanism operates to extend the output shaft, driving the negative pressure suction head 20 to rise through the notch 38 and contact the corresponding area to be cut. The negative pressure suction head 20 is connected to an external negative pressure device and can be firmly adsorbed to the aluminum plate through negative pressure. Subsequently, the laser cutting mechanism performs thermal cutting on the area to be cut of the aluminum plate below. During the process, adjust the position of the laser cutting head 7 through the second X-axis movement module 4, the second Y-axis movement module 5 and the second Z-axis movement module 6. It should be noted that the negative pressure suction head 20 can hold the area to be cut during the thermal cutting process, avoiding the cutting surface from being uneven due to material dropping deviation during the cutting process, which affects the product quality, and thus improving the final cutting accuracy. In addition, when replacing the aluminum plate subsequently, the material receiving and detecting assembly can also lift the aluminum plate in the stepped plate placing groove 3 through the rising negative pressure suction head 20, facilitating the staff to take it out.

[0055] Then, when the cut material is cut off, the flipping and material receiving mechanism directly receives it, avoiding dropping, bumping and being damaged, and thus ensuring the recycling value of the cut material. In addition, the flipping and material receiving mechanism can cooperate with the horizontal camera 26 and the vertical camera 25 to detect the quality and shape of the cutting surface in real time, and thus timely remove defective products. The specific detection process is as follows: First, lower the cut material into the chamber 8 through the cylinder 19, and then transfer the cut material to a preset position through the first Y-axis movement module 9, the first X-axis movement module 10 and the first Z-axis movement module 11. Immediately afterwards, the flipping motor 15 operates to drive the rotating block 14 to flip outwards by ninety degrees in the rotating groove 13 of the rotating seat 12, so that the L-shaped support plate 18 originally in a vertical state is switched to a horizontal state. At this time, the flipped cut material faces the horizontal camera 26. The horizontal camera 26 collects the shape image of the cut material and sends it to the background control terminal. The background control terminal performs real-time detection based on the collected image. At the same time, the setting of the supplementary light lamp 17 on the strip plate 16 can perform supplementary lighting to improve the detection effect. Immediately afterwards, the rotating motor 21 operates to drive the cut material to rotate one week. During the rotation process, the upper vertical camera 25 collects the cutting surface image of the cut material below and sends the cutting surface image to the background control terminal. The background control terminal performs real-time detection based on the collected image.

[0056] In addition, through the provided shielding component, when the quality and shape of the cutting surface are detected in real time, a relatively independent enclosed space can be provided for it, reducing the interference of external light from above and improving the detection accuracy. The specific working process of the shielding component is as follows: The horizontal linear motor 35 runs and slowly moves along the horizontal linear guide 34, causing the two strip-shaped docking plates 36 to approach each other. At the same time, the stepping motor 30 runs to drive the roller body 32 to rotate and release the shielding cloth 33. When the two strip-shaped docking plates 36 come into contact, the two strong magnets 37 are connected together by magnetic adsorption force, thereby improving the connection tightness of the two strip-shaped docking plates 36, and thus shielding the external light from above to a certain extent.

[0057] Based on the detection results of the background control terminal, it is judged whether the cut material is a good product or a defective product. If the cut material is a good product, the cut material is inserted into one of the slots 24 on the rubber conveyor belt 23 through the first Y-axis motion module 9, the first X-axis motion module 10, and the first Z-axis motion module 11. If the cut material is a defective product, the cut material is inserted into the other set of slots 24 on the rubber conveyor belt 23, and finally sent out of the chamber 8 through the rubber conveyor belt 23. This setting enables the waste or finished products after cutting to be sorted without manual labor, saving time and not easily causing material waste.

[0058] It should be noted that the components of the present application operate independently and cooperate with each other, which is convenient for equipment expansion and maintenance while improving the overall automation degree of the equipment.

[0059] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.

[0060] The above-mentioned is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
