Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0030] Please see Figure 1 and Figure 2 This embodiment provides a sheet laser cutting device, which includes a support platform 10, a storage bin 20, a straightening mechanism 30, a feeding mechanism 40 and a laser cutting assembly 50 disposed on the support platform 10.

[0031] The support platform 10 has a waste bin 101 in the middle and a gantry frame 102 horizontally arranged in the waste bin 101. The gantry frame 102 is "K" shaped. The waste bin 101 has a bin opening, and Y-axis moving modules 103 are respectively arranged on both sides of the bin opening. The two Y-axis moving modules 103 are equipped with suction fixing platforms 104. The suction fixing platform 104 includes a vacuum box and a suction plate arranged in the vacuum box. The suction plate has suction holes evenly arranged. The vacuum box is connected to the vacuum generator through a pipeline. The two suction fixing platforms 104 are set so that there is no need to wait for the material to be fed during cutting. They can be used in staggered cutting. One suction fixing platform 104 is used to cut with the laser cutting component 50, while the other suction fixing platform 104 is used to feed the material and wait for cutting.

[0032] The storage bin 20 is used to store the sheet materials to be cut. The sheet materials can be stacked in the storage bin 20. In order for the feeding mechanism 40 to easily grab the sheet materials, please refer to [link / reference needed]. Figure 4 Therefore, in this embodiment, the main structure of the storage bin 20 includes a positioning frame 201 and a lifting assembly 202 located at the bottom of the positioning frame 201 for lifting sheet materials. The positioning frame 201 includes a front positioning plate 2011, a rear positioning plate 2012, a left positioning rod 2013, and a right positioning rod 2014 spaced apart. The front positioning plate 2011, the rear positioning plate 2012, the left positioning rod 2013, and the right positioning rod 2014 form a hollow placement cavity. The lifting assembly 202 is located at the bottom of the placement cavity. There are two left positioning rods 2013 and two right positioning rods 2014, which are spaced apart. An mounting plate 2015 is provided on the side of the left positioning rod 2013 and the right positioning rod 2014. The mounting plate 2015 is equipped with a positioning sensor 2016 for detecting the set height of the sheet material lifted by the lifting assembly 202.

[0033] In addition, the lifting assembly 202 includes a fixed plate 2021, on which multiple guide rods 2022 are slidably mounted. The guide rods 2022 are connected to the fixed plate 2021 via linear bearings. A lifting plate 2023 is provided at the top of the guide rods 2022. A lead screw 2024 is threadedly connected to the middle of the fixed plate 2021, one end of which is rotatably connected to the lifting plate 2023. A bearing is provided at the connection between the lead screw 2024 and the lifting plate 2023. A driver 2025 is provided at the bottom of the lead screw 2024 to drive its rotation. A base is provided that is connected to the bottom of multiple guide rods 2022. A drive 2025 drives a lead screw 2024 to rotate. Since the lead screw 2024 is threadedly connected to a fixed plate 2021, when the lead screw 2024 rotates, the drive 2025 rises with the guide rods 2022, thereby driving the lifting plate 2023 to rise. When the positioning sensor 2016 senses the sheet material, the positioning sensor 2016 feeds back a signal to the drive 2025, causing the drive 2025 to operate in a positioning manner. In this embodiment, the drive 2025 is a motor.

[0034] The feeding mechanism 40 is used to transport the sheet material to be cut from the storage bin 20 to the suction fixing platform 104, and to remove the cut sheet material from the suction fixing platform 104. Please refer to [link / reference]. Figure 3 and Figure 6 Therefore, in this embodiment, the main structure of the feeding mechanism 40 includes a loading assembly 401 and a unloading assembly 402 located on both sides of the gantry frame 102. The loading assembly 401 and the unloading assembly 402 include a second X-axis moving module 4011 and a moving seat 4012 located on the second X-axis moving module 4011. The moving seat 4012 is equipped with a lifting slide cylinder 4013, and the output end of the lifting slide cylinder 4013 is equipped with a lifting seat 4014. The lifting seat 4014 is equipped with a suction cup 4015, and multiple buffer elements 4016 are arranged around the top circumference of the suction cup 4015. The buffer elements 4016 are connected to the lifting seat 4014 and are used to provide a buffering effect when picking up sheet material, avoiding damage to the sheet material. The second X-axis moving module 4011 can drive the moving seat 4012 to move along the X-axis direction on the gantry frame 102, thereby achieving precise horizontal positioning of the loading assembly 401 and the unloading assembly 402. The lifting slide cylinder 4013 is responsible for driving the lifting platform 4014 and the suction cup 4015 to rise and fall vertically, so as to pick up the sheet material to be cut from the storage bin 20 and transport it to the suction fixing platform 104, or to remove the sheet material from the suction fixing platform 104 after cutting. This design enables the feeding mechanism 40 to efficiently and accurately complete the conveying and removal of sheet material, improving the automation level and cutting efficiency of the laser cutting equipment.

[0035] To prevent the sheet material placed on the suction fixing platform 104 from shifting and to prevent unevenness in the cut sheet material, a straightening mechanism 30 is provided. Please refer to [link / reference]. Figure 5 In this embodiment, the main structure of the straightening mechanism 30 is a base 301 and a front push drive assembly and a side push drive assembly disposed on the base 301. The base 301 is provided with a photoelectric sensor 302 that detects the sheet material and is electrically connected to the Y-axis moving module 103. After the photoelectric sensor 302 detects the sheet material, it feeds back the signal to the Y-axis moving module 103, causing the Y-axis moving module 103 to position and operate. At the same time, the front push drive assembly and the side push drive assembly cooperate to push the suction fixing platform 10. The sheet material on the 4th is straightened; the forward push drive assembly includes a Y-axis guide rail 303, a first cylinder 304, a first horizontal push plate 305, and a first straightening plate 306. The Y-axis guide rail 303 is mounted on the base 301. The first horizontal push plate 305 is slidably mounted on the Y-axis guide rail 303, and one end of the first horizontal push plate 305 is connected to the first straightening plate 306, and the other end is connected to the output end of the first cylinder 304. The first cylinder 304 is fixed to the base 301; the side push drive assembly includes an X-axis guide rail 306. 07. The second cylinder 308, the second horizontal push plate 309, and the second straightening plate 310 are located on the side of the Y-axis guide rail 303 and fixed to the base 301. The second horizontal push plate 309 is slidably mounted on the X-axis guide rail 307, and one end of the second horizontal push plate 309 is connected to the second straightening plate 310. The output end of the second cylinder 308 is connected to the second straightening plate 310. The first horizontal push plate 305 is driven by the first cylinder 304 to move to the first straightening plate 306. The sheet is pushed forward towards the suction fixing platform 104. At the same time, the second cylinder 308 drives the second horizontal push plate 309 to move the second straightening plate 310 backward towards the suction fixing platform 104, pushing the sheet. When the front push drive assembly and the side push drive assembly are working, the straightening plates of the front push drive assembly and the side push drive assembly are perpendicular to each other to form an L-shape to straighten the sheet. Through this setting, the front push drive assembly and the side push drive assembly cooperate to adjust the position of the sheet and avoid the sheet on the suction fixing platform 104 from being misaligned.

[0036] The laser cutting assembly 50 is used to cut the excess material around the sheet material. The laser cutting assembly 50 is set on the gantry 102 and located between the loading assembly 401 and the unloading assembly 402. It includes a first X-axis moving module 501 and a laser cutting head 502 set on the first X-axis moving module 501. The excess material around the sheet material is removed by the left-right and front-back movement of the first X-axis moving module 501 and the Y-axis moving module 103.

[0037] During laser cutting by the laser cutting component 50, a large amount of debris and exhaust gas are generated. To prevent debris from floating and exhaust gas from polluting the working environment, the side wall of the debris and waste bin 101 is equipped with a perforated plate 1011. Each perforated plate 1011 is inclined, forming a cavity that is larger at the top and smaller at the bottom. The debris and waste bin 101 is equipped with a suction pipe connected to a vacuum cleaner. The vacuum cleaner uses the suction pipe to suck up the debris and exhaust gas from the debris and waste bin 101. The perforated plate 1011 prevents large pieces of debris from being sucked up, thus avoiding debris floating and exhaust gas pollution of the working environment and protecting the health of the workers. At the same time, the inclined perforated plate 1011 allows debris to slide smoothly to the bottom of the debris and waste bin 101, facilitating subsequent cleaning.

[0038] In summary, the working principle of this sheet laser cutting equipment is as follows: The sheet material to be cut is manually stacked in the storage bin 20. The lifting component 202 lifts the sheet material to the height to be picked up by the feeding component 401. The feeding component 401 then transports the sheet material to the suction fixing platform 104, where the suction fixing platform 104 firmly holds the sheet material. The Y-axis moving module 103 moves the sheet material on the suction fixing platform 104 to the straightening mechanism 30. The forward push drive component and the side push drive component work together to straighten the sheet material on the suction fixing platform 104, preventing misalignment. The Y-axis moving module 103 then straightens the sheet material. The sheet material is transferred to the laser cutting assembly 50, the laser cutting head 502 is activated, and at the same time the first X-axis moving module 501 and the Y-axis moving module 103 move left and right and back and forth to remove the excess material around the sheet material. After the cutting is completed, the Y-axis moving module 103 transfers the sheet material to the unloading assembly 402, and the unloading assembly 402 takes away the cut sheet material from the suction fixing platform 104. In the entire cutting process of this utility model, no manual material loading and unloading is required, the degree of automation is high, the processing time is less, the utilization rate and production capacity of the laser cutting machine are effectively improved, and the labor cost of enterprises is reduced.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
