Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting machines, and in particular relates to a laser cutting machine. Background Art

[0002] Laser cutting machine is to focus the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal; as the relative position of the beam and the workpiece moves, the material eventually forms a slit, thereby achieving the purpose of cutting; laser cutting processing replaces the traditional mechanical knife with an invisible beam, and has the characteristics of high precision, fast cutting, no limitation on cutting patterns, automatic typesetting to save materials, smooth incision, low processing cost, etc., which will gradually improve or replace the traditional metal cutting process equipment.

In this setting, it is ensured that the staff can control the servo motor 201 to operate through the controller. When the servo motor 201 is running, it can drive the rotating rod 2011 to rotate. When the rotating rod 2011 rotates, it can drive the guide sleeve 2014 to move vertically upward with the assistance of the guide slot 2012, the guide slider 2013 and the guide rod 2015.

[0037] like Figures 3 to 6 As shown, in a specific embodiment, a rotating rod 2025 is fixedly installed on each of the two hollow plates 202, and the two rotating rods 2025 are respectively rotatably connected to the inner wall of the laser cutting machine 101. A first slide 2021 is provided at the bottom of each of the two hollow plates 202, and the two first slides 2021 are symmetrical to each other. A first slider 2022 is slidably installed in the inner cavity of the two first slides 2021, and a special-shaped connecting rod 2023 is provided at the bottom of the two first sliders 2022. The other ends of the two special-shaped connecting rods 2023 are provided on the guide sleeve 2014, and the two special-shaped connecting rods 2023 are symmetrical to each other. A positioning block 2024 is fixedly connected to each of the two special-shaped connecting rods 2023. In this setting, it is ensured that when the guide sleeve 2014 moves vertically upward, it can push the hollow plate 202 to flip with the assistance of the first slide 2021, the first slider 2022 and the rotating rod 2025 through the special-shaped connecting rod 2023, so as to close.

[0038] Embodiment 3:

[0039] The difference between the above embodiment and the present embodiment 2 is that: Figures 3 to 6As shown, a laser cutting machine is provided, wherein two opposite side walls of the inner cavity of the laser cutting machine 101 are provided with special-shaped slide grooves 2042, and the inner cavities of the two special-shaped slide grooves 2042 are both provided with a plurality of movable sliders 2043 which are slidably arranged at equal intervals, and each movable slider 2043 is symmetrical with each other, and each movable slider 2043 is fixedly connected with a connecting plate 204 at one opposite end, and each movable slider 2043 is provided with a rocker rod 2044 between the two movable sliders 2043, and a fixing plate 2041 is provided at the bottom of one end of each rocker rod 2044 close to the rotating rod 2025. The inner cavity of the laser cutting machine 101 is also provided with four second slide rails 2034 that are symmetrical to each other. Each second slide rail 2034 is symmetrical to each other, and a slider is slidably provided in the inner cavity, and a movable plate 203 is fixedly connected between the sliders. The opposite side walls of the two movable plates 203 are provided with first slide rails 2032, and the two first slide rails 2032 are symmetrical to each other. The inner cavities of the two first slide rails 2032 are slidably provided with a slider, and the other end of the slider is provided with a fixed plate 2041. The opposite side walls of the two movable plates 203 are movably provided with movable rods 2031, and the other ends of the two movable rods 2031 are movably connected to the positioning block 2024. In this arrangement, it is ensured that when the special-shaped connecting rod 2023 is closed, it can drive the movable rod 2031 to move through its fixed positioning block 2024. When the movable rod 2031 moves, it can drive the movable plate 203 to move vertically with the assistance of the second slide rail 2034. When the movable plate 203 moves, because a fixed plate 2033 is slidingly arranged above it, the connecting plate 204 can be dragged by the fixed plate 2033 to move with the assistance of the special-shaped slide groove 2042 and the movable slider 2043. When the connecting plate 204 close to the fixed plate 2033 moves, it can drive other connecting plates 204 to move through the rocker rods 2044 connected in sequence, thereby realizing that the connecting plates 204 leave the top of the laser cutting machine 101 and are located on both sides.

[0040] like Figures 3 to 6As shown, further, the opposite ends of the two positioning blocks 2024 are fixedly connected with a wedge-shaped block 301, the two wedge-shaped blocks 301 are symmetrical to each other, and a moving block 3011 is arranged above the opposite side of the two wedge-shaped blocks 301, and the two moving blocks 3011 are respectively movable through the moving plate 203. The opposite ends of the two moving blocks 3011 are fixedly connected with a positioning plate 3014, and the opposite ends of each positioning plate 3014 are arranged with a mounting rod 3012, and each mounting rod 3012 is provided with a return spring 3013, and the other end of each return spring 3013 is respectively fixedly connected to the positioning plate 3014, and the other end is fixedly connected to the limit plate 3016. The opposite ends of the two moving blocks 3011 are fixedly connected with a connecting rod 3015, and the opposite ends of the two connecting rods 3015 are fixedly connected with a placement box 302. In this arrangement, it is ensured that when the positioning block 2024 moves vertically upward, it can also drive the wedge block 301 to move vertically upward. The inclined surface set at the wedge block 301 can push the moving block 3011 to move. When the moving block 3011 moves, it can drive the connecting rod 3015 to move. When the connecting rod 3015 moves, it can drive the placement box 302 to move to the outer wall of the laser cutting machine 101; and when the wedge block 301 moves to a certain position, the wedge block 301 will be located above the moving block 3011, and because its side wall is still inclined, the moving block 3011 can be reset with the assistance of the reset spring 3013, thereby ensuring that the placement box 302 can be located in the inner cavity of the laser cutting machine 101 at this time. When the placement box 302 is located outside the laser cutting machine 101, the staff can add desiccant to the placement cavity 3021 at this time. The desiccant is added to prevent the servo motor 201 from being damaged in humid conditions such as rainy days.

[0041] The implementation principle of a laser cutting machine in this embodiment is as follows:

[0042] First, when it is necessary to place cloth or plate, the staff can observe the connecting plate 204 and the hollow plate 202 provided on the laser cutting machine 101 to see whether they are used to carry cloth or plate (the connecting plate 204 is used to carry plate, and the hollow plate 202 is used to carry cloth);

[0043] When it is found that the hollow plate 202 carrying the cloth is in an open state, and the carrying connecting plate 204 is located on the laser cutting machine 101, the staff controls the servo motor 201 to operate through the controller. When the servo motor 201 operates, it can drive the rotating rod 2011 to rotate. When the rotating rod 2011 rotates, it can drive the guide sleeve 2014 to move vertically upward with the assistance of the guide slot 2012, the guide slider 2013 and the guide rod 2015. When the guide sleeve 2014 moves vertically upward, it can push the hollow plate 202 through the special-shaped connecting rod 2023 to flip with the assistance of the first slot 2021, the first slider 2022 and the rotating rod 2025, so as to close;

[0044] At the same time, when the special-shaped connecting rod 2023 is closed, it can drive the movable rod 2031 to move through its fixed positioning block 2024. When the movable rod 2031 moves, it can drive the movable plate 203 to move vertically with the assistance of the second slide rail 2034. When the movable plate 203 moves, because the fixed plate 2033 is slidably arranged above it, the connecting plate 204 can be dragged by the fixed plate 2033 to move with the assistance of the special-shaped slide groove 2042 and the movable slider 2043. When the connecting plate 204 close to the fixed plate 2033 moves, it can drive other connecting plates 204 to move through the swing rods 2044 connected in sequence, so that the connecting plates 204 leave the top of the laser cutting machine 101 and are located on both sides.

[0045] At the same time, when the positioning block 2024 moves vertically upward, it can also drive the wedge block 301 to move vertically upward, and the inclined surface set at the wedge block 301 can push the moving block 3011 to move, and when the moving block 3011 moves, it can drive the connecting rod 3015 to move, and when the connecting rod 3015 moves, it can drive the placement box 302 to move to the outer wall of the laser cutting machine 101 (when the wedge block 301 moves to a certain position, the wedge block 301 will be located above the moving block 3011, and because its side wall is still inclined, the moving block 3011 can be reset with the assistance of the reset spring 3013, thereby ensuring that the placement box 302 can be located in the inner cavity of the laser cutting machine 101 at this time, wherein the placement box 302 is located outside the laser cutting machine 101, at this time, the staff can add desiccant to the placement cavity 3021, wherein the desiccant is added to prevent the servo motor 201 from being damaged in humid conditions such as rainy days);

[0046] When the two hollow plates 202 are turned over and parallel to each other, the staff can place the cloth on the hollow plate 202 and start the vacuum pump 103 to evacuate the bottom of the hollow plate 202 from the inner cavity of the laser cutting machine 101, so that the debris generated during the cutting process can enter the collection box 102 from the connecting pipe 1031. Because the collection box 102 is provided with a collection box 1021, and the opening side of the collection box 1021 is located at the connecting pipe 1031, it can ensure that the debris is collected. When the debris needs to be processed, the collection box 1021 can be pulled out by the handle provided on the collection box 1021, so that the debris in the collection box 1021 can be processed.

[0047] By observing the position between the hollow plate 202 and the connecting plate 204 when placing different cloths or plates, when they do not match, the hollow plate 202 can be opened and closed by controlling the driving component, and the connecting plate 204 can be controlled to move to above the laser cutting machine 101 or leave the laser cutting machine 101 when the driving component moves, so that the hollow plate 202 is located above the laser cutting machine 101 or the connecting plate 204 is located in the laser cutting machine 101. At the same time, the driving component can also drive the placement box 302 to leave the inner cavity of the laser cutting machine 101 first and then enter the inner cavity of the laser cutting machine 101. When the placement box 302 leaves, a desiccant can be added thereto.
