The waste cart, filled with waste, is periodically pulled out manually and then shoveled into a waste collection box. The whole process requires a lot of manual operation, resulting in high labor costs, reduced production efficiency, and the production line may be affected by untimely waste removal.

[0048] See Figures 1 to 11 This application provides a laser processing production line. The laser processing production line includes a laser cutting device 100 and a waste cleaning device 200.

[0049] The laser cutting device 100 includes a cutting machine tool 110 and a cutting worktable 120 mounted on the cutting machine tool 110.

[0050] At least a portion of the waste cleaning device 200 is disposed below the laser cutting device 100.

[0052] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0053] Embodiment 1 of the laser processing production line of this application

[0054] like Figures 1 to 4 As shown, the laser processing production line includes a laser cutting device 100 and a waste cleaning device 200. The laser cutting device 100 is used to perform laser cutting on the sheet metal, and the waste cleaning device 200 is used to transport and collect the cutting waste that falls off the sheet metal.

[0055] The laser cutting device 100 includes a cutting machine tool 110 and a cutting worktable 120 mounted on the cutting machine tool 110. The cutting machine tool 110 is used to perform laser cutting on sheet metal, and the cutting worktable 120 is used to support the sheet metal, specifically including the sheet metal to be processed and the processed sheet metal.

[0056] At least a portion of the waste cleaning device 200 is disposed below the laser cutting device 100. The waste cleaning device 200 includes a waste guiding mechanism 210, a waste conveying mechanism 220, and a waste collection box 230. The waste guiding mechanism 210 is disposed between the laser cutting device 100 and the waste conveying mechanism 220, and the waste collection box 230 is installed at the end of the conveying direction of the waste conveying mechanism 220.

[0057] The working principle of this laser processing production line is as follows: The sheet material to be processed is placed on the cutting worktable 120 and then transported by the cutting worktable 120 to the cutting machine tool 110, where the cutting machine tool 110 performs laser cutting on the sheet material. After cutting, the processed sheet material remains on the cutting worktable 120, and the cutting waste falls into the waste cleaning device 200 located below the laser cutting device 100 due to gravity. Specifically, the cutting waste falls along the waste guiding mechanism 210 onto the waste conveying mechanism 220, and is then transported by the waste conveying mechanism 220 to the waste collection box 230. This laser processing production line does not require a waste cart, and no manual intervention is needed during the waste cleaning process. Instead, automated waste cleaning is achieved through the cooperation of the waste guiding mechanism 210 and the waste conveying mechanism 220. The waste conveying mechanism 220 enables uninterrupted waste transportation, thereby avoiding the problem of waste accumulation affecting the operation of the production line.

[0058] In this embodiment, the laser cutting device 100 also includes a machine tool housing 130 (see...). Figure 7 The machine tool cover 130 is located on the outside of the cutting machine tool 110.

[0059] like Figure 1 and Figure 2 As shown, in this embodiment, the waste guiding mechanism 210 includes an above-ground guide 211 and an underground guide 212. One end of the above-ground guide 211 is connected to the laser cutting device 100, and the other end is located above the underground guide 212. The underground guide 212 is disposed between the above-ground guide 211 and the waste conveying mechanism 220.

[0060] Specifically, both the above-ground guide 211 and the underground guide 212 are used to guide the cutting waste onto the waste conveying mechanism 220. In this embodiment, the laser cutting device 100 is located above ground A, and a portion of the waste cleaning device 200 is located below ground A in order to reduce the space occupied by the waste cleaning device 200.

[0061] The above-ground guide 211 is positioned above ground level A. One end of the above-ground guide 211 is hung on the laser cutting device 100, and the other end is tangent to ground level A, with ground level A providing support to form a guide ramp between the laser cutting device 100 and ground level A. The underground guide 212 is positioned below ground level A. One end of the underground guide 212 is connected to the above-ground guide 211, and the other end is connected to the waste conveying mechanism 220.

[0062] This application uses above-ground guide 211 and underground guide 212 to guide falling cutting waste. On the one hand, it can prevent cutting waste from falling into the gap between the laser cutting device 100 and the ground A. On the other hand, it can effectively utilize the supporting force of the ground A on the above-ground guide 211, avoiding the problem of needing to add other support structures due to the excessively long guiding distance of a single guide. This simplifies the structure of the waste cleaning device 200 and saves on the assembly difficulty and cost of the production line.

[0063] like Figure 1 As shown, in this embodiment, the above-ground guide 211 forms a first slope angle α with the horizontal plane, and the underground guide 212 forms a second slope angle β with the horizontal plane. Both the first slope angle α and the second slope angle β are less than 90°, and the first slope angle α is less than the second slope angle β.

[0064] Specifically, the first slope angle α is less than the second slope angle β, that is, the slope of the above-ground guide 211 is less than the slope of the underground guide 212, so that the connection between the above-ground guide 211 and the underground guide 212 is smoother, ensuring that the cutting waste can fall smoothly from the above-ground guide 211 and the underground guide 212 onto the waste conveying mechanism 220.

[0065] In some embodiments, the first ramp angle α can also be equal to the second ramp angle β, so that the guide surface of the ground guide 211 and the guide surface of the ground guide 211 are located on the same ramp.

[0066] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the waste conveying mechanism 220 includes a first waste conveying motor 221 and a conveying chain plate 222 that is connected to the first waste conveying motor 221 for transmission. The conveying chain plate 222 is made of metal sheet.

[0067] Specifically, the first waste conveying motor 221 drives the conveyor chain 222, enabling it to transport the cutting waste to the waste collection box 230. The conveyor chain 222 is made of metal sheet to prevent damage from the hot cutting waste located below the cutting position. In this embodiment, the conveyor chain 222 is made of stainless steel, providing better protection and preventing direct damage from the hot cutting waste.

[0068] like Figure 2 and Figure 6 As shown, in this embodiment, the laser processing production line is provided with a cutting area c and a loading and unloading area d. The cutting machine tool 110 is located in the cutting area c, and the cutting worktable 120 is slidably disposed on the cutting machine tool 110.

[0069] When the laser processing production line is in the cutting state, the cutting worktable 120 is located within the cutting area c;

[0070] When the laser processing production line is in the loading and unloading state, the cutting worktable 120 is located within the loading and unloading area d.

[0071] The waste conveying mechanism 220 also includes a second waste conveying motor 223 and a conveyor belt 224 that is connected to the second waste conveying motor 223. The conveyor belt 224 is located in the loading and unloading area d and below the cutting worktable 120 that enters the loading and unloading area d. The conveyor chain plate 222 is located in the cutting area c and below the cutting machine tool 110.

[0072] Specifically, the cutting worktable 120 can switch back and forth between the cutting area c and the loading / unloading area d. For example... Figure 2 As shown, before cutting begins, the laser processing production line is in the loading state, with the cutting worktable 120 located within the loading / unloading area d to support the sheet metal to be processed. After loading is complete, the cutting worktable 120 and the sheet metal to be processed enter the cutting area c together for laser cutting, as shown. Figure 6 As shown. After cutting, the cutting worktable 120 and the processed sheet material re-enter the loading and unloading area d, waiting for the loading and unloading device 300 to unload.

[0073] Specifically, the end of the cutting worktable 120 that enters the loading and unloading area d is farther away from the cutting machine tool 110 than 650mm from the cutting machine tool 110, so as to ensure that the cutting worktable 120 has enough space for the loading and unloading device 300 to perform loading and unloading operations.

[0074] In this embodiment, the cutting area c is the working area for laser cutting, and the loading / unloading area d is the area where the sheet metal awaits loading / unloading before and after cutting. This application ensures that the conveyor chain plate 222 in the cutting area c is not damaged by cutting sparks or high-temperature waste during the cutting process by setting a conveyor chain plate 222 in the cutting area c and a conveyor belt 224 in the loading / unloading area d. Since some waste material may not fall immediately after cutting but follows the cut sheet metal into the loading / unloading area d before falling, the temperature of the waste material is relatively low, reducing the risk of damage to the transmission mechanism due to high temperature. This application uses a conveyor belt 224 in the loading / unloading area d to clean and transport the waste material that falls into the loading / unloading area d, and also saves on production line costs. This application uses the cooperation of the conveyor chain plate 222 and the conveyor belt 224 to transport the cutting waste, which can efficiently and comprehensively clean the cutting waste generated during the cutting process and has the advantage of reducing costs.

[0075] In this embodiment, the conveyor belt 224 and the conveyor chain plate 222 have the same conveying direction, and the conveyor belt 224 conveys the cutting waste towards the conveyor chain plate 222, such as... Figure 1 As shown, the distance from the conveyor belt 224 to the cutting table 120 is less than the distance from the conveyor chain plate 222 to the cutting table 120, enabling the conveyor belt 224 to transport the cutting waste onto the conveyor chain plate 222, and then the conveyor chain plate 222 to transport the cutting waste into the waste collection box 230. This embodiment also allows for maintaining a larger distance between the conveyor chain plate 222 and the cutting table 120, preventing damage to the waste conveying mechanism 220 from the laser cutting device 100.

[0076] In this embodiment, the distance between the laser cutting device 100 and the waste cleaning device 200 is between 1 meter and 2 meters.

[0077] Specifically, the distance between the cutting worktable 120 in cutting area c and the waste conveying mechanism 220 ranges from 1 meter to 2 meters. Specifically, the distance between the cutting worktable 120 in cutting area c and the waste conveying mechanism 220 is 1.5 meters.

[0078] In some embodiments, the conveyor chain plate 222 can be configured to convey the cutting waste bin to the conveyor belt 224 in the direction of the conveyor chain plate 222. The distance from the conveyor chain plate 222 to the cutting worktable 120 is less than the distance from the conveyor belt 224 to the cutting worktable 120, so that the conveyor chain plate 222 can transport the cutting waste onto the conveyor belt 224, and then the conveyor belt 224 can transport the cutting waste to the waste collection bin 230.

[0079] like Figures 1 to 7 As shown, in this embodiment, the underground guide 212 includes a first guide 2121 and a second guide 2122. The first guide 2121 is disposed in the cutting area c and is located between the ground guide 211 and the conveyor chain plate 222. The second guide 2122 is disposed in the loading and unloading area d and is located between the ground guide 211 and the conveyor belt 224.

[0080] Specifically, since the distances from the conveyor belt 224 to the cutting table 120 and from the conveyor chain plate 222 to the cutting table 120 are different, this embodiment uses a first guide member 2121 to guide the cutting waste falling in the cutting area c, and a second guide member 2122 to guide the cutting waste falling in the loading and unloading area d, so that the cutting waste in each area can fall smoothly onto the corresponding conveyor chain plate 222 and conveyor belt 224. The waste cleaning device 200 of this application has strong adaptability.

[0081] like Figure 1 As shown, in this embodiment, the distance from the conveyor belt 224 to the cutting table 120 is less than the distance from the transmission plate chain to the cutting table 120. The first guide member 2121 forms a first angle with the horizontal plane, and the second guide member 2122 forms a second angle with the horizontal plane. The first angle is greater than the second angle.

[0082] Specifically, the first included angle ranges from 55° to 65°, and the second included angle ranges from 45° to 50°. In this embodiment, the first included angle is 60°, and the second included angle is 50°. Within the above-mentioned included angle range, the cutting waste can be smoothly placed onto the waste conveying mechanism 220.

[0083] like Figure 2 As shown, in this embodiment, the waste conveying mechanism 220 also includes a partition guide 213. The partition guide is set in the cutting area c, and in the top view of the laser processing production line, the partition guide 213 and the ground guide 211 located in the cutting area c enclose a waste collection area.

[0084] Specifically, the partition guide 213 divides the cutting area c into multiple waste collection areas, so that cutting waste falling into the same waste collection area can be collected in a concentrated manner.

[0085] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the waste conveying mechanism 220 also includes a protective brick 240, which is disposed above the ground guide 211 and the partition guide 213.

[0086] Specifically, the protective brick 240 is positioned between the cutting table 120 and the waste guiding mechanism 210 to protect the waste guiding mechanism 210 and prevent high-temperature waste from damaging the ground guide component 211 and the partition guide component 213. The protective brick 240 blocks the space between the cutting table 120 and the waste guiding mechanism 210, forming an acute angle with the ground A, allowing cutting waste falling onto the waste guiding mechanism 210 smoothly. The partition guide component 213 can also integrate the installation of the protective brick 240. The protective brick 240 in this application is a refractory brick.

[0087] like Figure 1 As shown, in this embodiment, the underground guide 212, conveyor chain plate 222, and conveyor belt 224 are all installed in the underground trench. The above-ground guide 211 overlaps the edge of the trench, and the edge of the trench on the ground surface A supports the above-ground guide 211. The waste guiding mechanism 210 also includes a guide support frame 214, which is connected to the above-ground guide 211 to support the above-ground guide 211, so that the underground guide 212 forms an inclined surface, allowing the cutting waste to fall smoothly onto the conveyor chain plate 222 and conveyor belt 224.

[0088] like Figure 1 and Figure 4 As shown, in this embodiment, the waste conveying mechanism 220 further includes a climbing conveyor chain 225 and a conveyor chain support frame 226. The beginning of the climbing conveyor chain 225 is connected to the conveyor chain plate 222, and the end is connected to the waste collection box 230. It is used to receive the cutting waste from the conveyor chain plate 222 and transport the cutting waste to the waste collection box 230. The climbing conveyor chain 225 can climb and transport the cutting waste on the underground conveyor chain plate 222 and conveyor belt 224 to the waste collection box 230 located on the ground, without the need for manual handling and lifting. The conveyor chain support frame 226 is located below the climbing conveyor chain 225 and is used to support the portion of the climbing conveyor chain 225 that is exposed above ground A.

[0089] The angle between the climbing conveyor chain 225 and the ground plane is less than or equal to 45°. In this embodiment, the angle between the climbing conveyor chain 225 and the ground plane is 29°, which can prevent the cutting waste from slipping during the climbing and conveying process.

[0090] like Figure 7 , Figure 8 and Figure 9As shown, in this embodiment, the laser processing production line also includes a loading and unloading device 300. The loading and unloading device 300 is disposed on one side of the laser cutting device 100. The loading and unloading device 300 includes a connecting bracket 310, a suction cup mechanism 320 and a fork mechanism 330. The suction cup mechanism 320 and the fork mechanism 330 are both disposed on the connecting bracket 310.

[0091] When the loading and unloading device 300 is in the loading state, the suction cup mechanism 320 places the plate to be processed b on the cutting worktable 120;

[0092] When the loading and unloading device 300 is in the unloading state, the fork mechanism 330 removes the processed sheet metal from the cutting worktable 120.

[0093] Specifically, the loading / unloading device 300 and the laser cutting device 100 are structurally independent but interact with each other in operation. In this embodiment, the loading / unloading device 300 is located on one side of the laser cutting device 100, so that the loading / unloading device 300 can interact with the cutting worktable 120 of the laser cutting device 100, thereby realizing the loading / unloading operation of the sheet metal.

[0094] Specifically, the loading and unloading process of the loading and unloading device 300 is as follows:

[0095] During loading, a suction cup mechanism 320 picks up the material to be processed, moves it above the cutting table 120, and then places it on the cutting table 120. The cutting table 120 carries the material to be processed into the cutting machine tool 110 for laser cutting.

[0096] During the unloading process, the cutting workbench 120 transports the cut sheet to the loading and unloading area d, and the forklift mechanism 330 uses a forklift to lift the cut sheet and place it in the predetermined flat area, thus completing the cutting process.

[0097] This application sets up a loading and unloading device 300 with a suction cup mechanism 320 and a fork mechanism 330, so that the suction cup mechanism 320 and the fork mechanism 330 work together to realize the automated loading and unloading of the laser processing production line, effectively reducing labor costs and improving loading and unloading efficiency.

[0098] like Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in this embodiment, the cutting workbench 120 includes a first workbench 121 and a second workbench 122 slidably disposed on the first workbench 121. Both the first workbench 121 and the second workbench 122 are provided with at least two support bars 123, and there is a spacing between two adjacent support bars 123 for the fork of the fork mechanism 330 to enter.

[0099] Specifically, the first worktable 121 and the second worktable 122 can alternately enter the cutting area c to improve laser processing efficiency: after the first worktable 121 carries the material to be processed into the cutting area c, the second worktable 122 cooperates with the loading and unloading device 300 in the loading and unloading area d to perform loading operation; after the material on the first worktable 121 is cut, the first worktable 121 moves to the loading and unloading area d and cooperates with the loading and unloading device 300 to perform unloading operation, and the second worktable 122 carries the material to be processed in the cutting area c. This alternating cutting and loading and unloading operation is repeated, which greatly improves processing efficiency.

[0100] In this embodiment, the second workbench 122 and the first workbench 121 are arranged in an upper and lower layer, which can avoid interference between the two workbench during the alternating entry into the cutting area c and the loading and unloading area d, making the processing process smoother.

[0101] In this embodiment, both the first workbench 121 and the second workbench 122 are provided with support bars 123. The support bars 123 are used to support the plates to be processed and the plates that have been processed. The support bars 123 enable the forks of the fork mechanism 330 to extend into the gap between adjacent support bars 123 so that the forks can perform material picking operations.

[0102] The support bar 123 is used to support the plate, and the first workbench 121 and the second workbench 122 can be set as hollow structures, which is conducive to the waste generated during the cutting process falling smoothly into the waste cleaning device 200 below.

[0103] In this embodiment, the laser cutting device 100 further includes a fixed worktable 140, which is connected to the cutting worktable 120 to support it. Specifically, the first worktable 121 and the second worktable 122 are both mounted on the fixed worktable 140.
