Description

Technical Field

[0001] This utility model relates to the field of waste separation technology for cutting machines, specifically an automatic waste separation device for laser cutting machines. Background Technology

[0002] Laser cutting machines, with their advantages of high cutting precision, high speed, and strong adaptability, have become core equipment in industrial fields such as metal processing and sheet metal manufacturing. During laser cutting operations, a large amount of scrap material is generated after the workpiece is cut. If this scrap material cannot be removed from the work area in a timely and efficient manner, it will not only occupy the cutting station and affect the progress of subsequent operations, but may also cause problems such as cutting head collision and workpiece positioning deviation due to the accumulation of scrap material, directly affecting the continuous operation and processing accuracy of laser cutting. Therefore, the scrap separation process is an important part of the laser cutting production process, and its efficiency and stability have a key impact on the overall production efficiency.

[0003] However, currently, most laser cutting machine waste disposal still relies on traditional manual cleaning methods. This method is due to two main reasons: firstly, the early laser cutting workload was relatively small, and manual cleaning was efficient enough to meet production needs; secondly, traditional automated separation devices generally suffer from complex structures, high costs, and poor adaptability, making them difficult to popularize in small and medium-sized processing scenarios. Therefore, manual cleaning has been used for a long time. However, as the manufacturing industry develops towards high efficiency and continuous operation, the drawbacks of manual cleaning have become increasingly apparent. Due to poor operational continuity, the laser cutting machine must be paused when manually cleaning waste, resulting in interruptions in the cutting process and a significant reduction in overall production efficiency. This is especially true in large-scale continuous cutting operations, where the capacity loss caused by downtime for cleaning is even more significant. Therefore, there is an urgent need for an automatic waste separation device for laser cutting machines. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a new technical solution: an automatic waste separation device for laser cutting machines, including a rectangular support box 1: the rectangular support box 1 provides a stable installation benchmark for all functional components, and the rectangular through groove 2 realizes the entry and exit channels of workpieces and waste, which is the core framework of the automatic waste separation process.

[0018] Conveying mechanism 5: Located below the inclined plate 4, the conveying mechanism 5 is used to receive the waste material sliding down from the inclined plate 4 and transport the waste material away from the laser cutting operation area through the conveyor belt, realizing the directional conveying and collection of waste material. It is the end conveying component for automatic waste separation.

[0019] Rectangular through groove 2: The rectangular through groove 2 serves as both the discharge channel for waste material and the moving channel for the push plate 8, ensuring that the waste material can be smoothly moved out of the rectangular support box 1, while providing moving space for the push plate 8.

[0020] First cylinder 7: The first cylinder 7 is fixedly connected to the middle position of the lower surface of the rectangular support box 1. The telescopic end of the first cylinder 7 slides through the interior of the rectangular support box 1 and is fixedly connected to the workpiece placement plate 6. The first cylinder 7 is the power source for the lifting and lowering of the workpiece placement plate 6. The telescopic end drives the workpiece placement plate 6 to move up and down, thereby realizing the switching between the cutting station and the waste separation station.

[0021] Workpiece placement plate 6: The workpiece placement plate 6 is fixedly connected to the telescopic end of the first cylinder 7. The workpiece placement plate 6 is slidably connected to the inner wall of the rectangular support box 1. Four guide rods 9 are fixedly connected to the lower surface of the workpiece placement plate 6. The workpiece placement plate 6 is used to place the workpiece to be cut and to carry the waste material after cutting. The sliding cooperation with the inner wall of the rectangular support box 1 ensures smooth lifting and is the carrier for separating laser cutting and waste material.

[0022] Guide rods 9: All four guide rods 9 are fixedly connected to the lower surface of the workpiece placement plate 6. The lower ends of the four guide rods 9 slide through the lower surface of the rectangular support box 1. The guide rods 9 rise and fall synchronously with the workpiece placement plate 6, which plays a guiding and constraining role in the rise and fall of the workpiece placement plate 6, preventing the workpiece placement plate 6 from shifting or shaking when it moves, and improving the stability of the rise and fall.

[0023] Mounting bracket 14: Mounting bracket 14 provides a stable mounting support for the second cylinder 12, positioning the second cylinder 12 at a position corresponding to the right rectangular through slot 2, ensuring that the push plate 8 can accurately push the waste material.

[0024] Second cylinder 12: The second cylinder 12 is fixedly connected to the upper surface of the mounting bracket 14. The extension end of the second cylinder 12 is fixedly connected to the push plate 8. The second cylinder 12 is the power source for the horizontal movement of the push plate 8. The extension and retraction of the extension end drives the push plate 8 to move left and right, thereby pushing and separating the waste material on the workpiece placement plate 6.

[0025] Push plate 8: Driven by the second cylinder 12, push plate 8 moves to the left and pushes the waste material by fitting the surface of the waste material through the arc groove 13, so as to realize the movement of the waste material to the left rectangular through groove 2. The snap-fit ​​of the right rectangular through groove 2 ensures that the push plate 8 moves in a precise direction.

[0026] Arc groove 13: Arc groove 13 is provided on the left side of push plate 8. Arc groove 13 is used to increase the contact area between push plate 8 and waste material, so that push plate 8 can closely fit the surface of waste material, avoid waste material from slipping during the pushing process, and ensure that the pushing action is stable and reliable.

[0027] Concave plate 10: Concave plate 10 provides a sliding guide channel for auxiliary rod 11. Through cooperation with auxiliary rod 11, it further constrains the movement trajectory of push plate 8 and prevents push plate 8 from shifting up and down or forward and backward when it moves.

[0028] Auxiliary rod 11: Both auxiliary rods 11 are fixedly connected to the right side of the push plate 8. The right ends of the two auxiliary rods 11 slide through the right side of the corresponding concave plate 10. The auxiliary rods 11 move synchronously with the push plate 8 and provide additional support for the push plate 8 under the guidance of the concave plate 10, thereby enhancing the stability of the horizontal movement of the push plate 8 and ensuring a smooth material pushing process.

[0029] Inclined plate 4: Inclined plate 4 is used to assist waste material in falling into the conveyor belt of conveying mechanism 5. Its inclined setting uses gravity to guide the waste material to slide down the plate surface, avoiding the accumulation of waste material at the outlet of rectangular through groove 2, and realizing the precise guidance of waste material to conveying mechanism 5.

[0030] Laser cutting machine moving frame mounting plate 3: Laser cutting machine moving frame mounting plate 3 is used for the installation of the laser cutting machine moving frame, ensuring that the laser cutting head on the laser cutting machine moving frame can accurately align with the workpiece on the workpiece placement plate 6 for cutting. It is a basic component for precise positioning of the laser cutting station.

[0031] Furthermore, when using the automatic waste separation device of this laser cutting machine, when the waste needs to be processed after cutting is completed; First, the first cylinder 7 is started. The telescopic end of the first cylinder 7 drives the workpiece placement plate 6 to move downward. After the workpiece placement plate 6 moves to the designated position, the first cylinder 7 is closed. At this time, the push plate 8 and the waste are set to correspond left and right. Then, the second cylinder 12 is activated. The telescopic end of the second cylinder 12 pushes the push plate 8 to move to the left. The two auxiliary rods 11 on the right side of the push plate 8 slide along the inner wall of the corresponding concave plate 10. The cooperation between the concave plate 10 and the auxiliary rods 11 provides horizontal guidance for the push plate 8, preventing the push plate 8 from shifting up and down or back and forth when it moves. The arc groove 13 on the left side of the push plate 8 fits against the surface of the waste material, increasing the contact area between the push plate and the waste material, preventing the waste material from slipping during the pushing process, and ensuring that the push plate 8 can stably push the waste material to move to the left rectangular through groove 2. As the pusher plate 8 continues to move, the waste is pushed into the rectangular channel 2 on the left side of the rectangular support box 1. Then the waste falls from the rectangular channel 2 onto the inclined plate 4 below. The inclined plate 4 is set at an angle, and the waste is guided to slide down the plate surface by gravity, so as to avoid the waste accumulating at the outlet of the rectangular channel 2. At the same time, the guiding effect of the inclined plate 4 makes the waste fall accurately onto the conveyor belt of the conveying mechanism 5 below, so as to realize the directional conveying of the waste. When the waste falls into the conveying mechanism 5, the conveying mechanism 5 is started and the conveyor belt transports the waste away from the laser cutting operation area, completing the automatic separation and collection of the waste. At this time, the extension end of the second cylinder 12 is controlled to retract, driving the push plate 8 and the auxiliary rod 11 to move in the opposite direction and reset. The push plate 8 slides out from the inner wall of the rectangular through groove 2 and returns to the initial position so as to carry out the next waste processing operation. If the cutting operation needs to continue, the extension end of the first cylinder 7 is activated to move the workpiece placement plate 6 and guide rod 9 upward and reset. The workpiece placement plate 6 returns to the laser cutting station. At this time, a new workpiece to be cut can be placed on the workpiece placement plate 6. The laser cutting machine moving frame mounting plates 3 on the left and right sides of the rectangular support box 1 are used to install the laser cutting machine moving frame to ensure that the laser cutting head can accurately align with the workpiece on the workpiece placement plate 6 for cutting. After the cutting is completed, the above waste separation steps can be repeated. In the entire waste separation process, the rectangular support box 1 provides stable installation support for each component, and the rectangular through groove 2 realizes the entry and exit channel for workpieces and waste. Compared with the problems of traditional laser cutting machines that require manual cleaning of waste, low efficiency and easy to affect the continuity of operation, this device uses a cylinder-driven unloading-guided pushing-tilting conveying-collection automated process, combined with multiple sets of guide structures to ensure accurate and stable separation, realize the rapid automatic separation of waste after cutting, reduce manual intervention, and improve the overall efficiency and continuity of laser cutting operations.

[0032] Example 1: Application of multi-tooth comb-shaped pusher plate replacing the original pusher plate 8 in small-scale scattered waste separation scenarios When a certain electronic component factory processes small and scattered stainless steel parts, the waste generated after laser cutting is small in size, numerous in quantity, and scattered. The arc groove 13 of the original push plate 8 can only fit the surface of a single size of waste. When pushing the scattered small waste, it is easy to miss or slip, resulting in some waste remaining on the workpiece placement plate 6, which requires manual secondary cleaning and affects the continuity of the operation. At the same time, the scattered waste is easy to squeeze and shift during the pushing process, making it impossible to accurately enter the rectangular through groove 2, reducing the separation efficiency. At this time, the original push plate 8 is replaced with a multi-tooth comb-shaped push plate with the same installation size as the original component. Multiple sets of parallel comb teeth are set on the left side of the push plate, and the spacing of the comb teeth is adapted to the size of the small waste. The parallel teeth of the multi-tooth comb-shaped pusher can hook multiple scattered waste materials at the same time, avoiding missed pushes and slippage, and realizing batch synchronous push. The tooth spacing is adapted to the size of small waste materials, which can neatly gather the scattered waste materials, prevent mutual squeezing and displacement, and ensure that all waste materials accurately enter the rectangular through groove 2. It solves the problems of incomplete push and inaccurate positioning of scattered waste materials by traditional pushers, and meets the core requirements of "batch gathering and precise separation" of small scattered waste materials. The rigid structure of the comb teeth can penetrate deep into the gaps between the waste materials, forming multi-point positioning support. The waste material posture is stable during the pushing process. In coordination with the power output of the second cylinder 12, the comb-shaped structure disperses the thrust, avoiding waste material overturning caused by a single contact point, further improving the pushing stability. In coordination with the guiding structure of the concave plate 10 and the auxiliary rod 11, the pusher plate moves with precision. The gathered waste material can pass smoothly through the rectangular through groove 2 without manual intervention and calibration, ensuring a continuous and efficient separation process. The installation interface of the multi-tooth comb-shaped push plate and its connection method with the second cylinder 12 are completely the same as the original push plate 8. It can be directly replaced and installed without modifying the structure of the mounting bracket 14 and the auxiliary rod 11. The overall thickness and width of the push plate are the same as the original part, which does not affect the fit clearance with the rectangular through slot 2 and the lifting space of the workpiece placement plate 6. The comb teeth are made of wear-resistant metal material, and the service life is comparable to that of the original push plate. During maintenance, only the push plate needs to be replaced. The operation process is the same as the original part, and it can be quickly adapted to the existing small-scale scattered waste separation production line.

[0033] Example 2: Application of low-friction coated inclined plate replacing the original inclined plate 4 in the separation of viscous waste. When a machining plant processes coated stainless steel sheets, the waste generated after laser cutting has residual adhesive coating material on its surface. The original inclined plate 4 was made of ordinary metal sheet with high surface friction, and the adhesive waste easily stuck to the plate surface when it slid down, causing it to accumulate and block the outlet of the rectangular channel 2. This required manual cleaning of the accumulated waste, interrupting the operation. At the same time, the stuck waste affected the trajectory of subsequent waste, causing secondary deviation and preventing it from accurately falling into the conveying mechanism 5, thus reducing the reliability of separation. In this case, the original inclined plate 4 was simply replaced with a low-friction coated inclined plate with the same installation dimensions as the original component. The plate surface was sprayed with a low-friction ceramic coating, which significantly improved the surface smoothness. The low-friction ceramic coating significantly reduces the surface friction of the inclined plate, so that sticky waste does not stick and accumulate when it slides down, and can slide smoothly along the plate surface, avoiding blockage of the rectangular through groove 2 outlet. This solves the problem of sticky waste sticking caused by high friction in traditional inclined plates. The coating surface is smooth and wear-resistant, and even long-term contact with sticky substances does not affect the smoothness, ensuring that the waste always slides down along the preset trajectory and falls accurately into the conveying mechanism 5, which meets the core requirements of non-sticking and smooth separation of sticky waste. The hydrophobic and oleophobic properties of the low-friction coating can reduce the adhesion of sticky substances, further reducing the resistance of waste sliding. In conjunction with the outlet position of the rectangular channel 2, the sliding waste can quickly enter the conveying mechanism 5 without manual assistance, avoiding secondary displacement caused by accumulation. In conjunction with the conveyor belt of the conveying mechanism 5, the smoothly sliding waste can be evenly distributed on the conveyor belt, preventing accumulation and compression, improving collection efficiency, and ensuring that the separation process is continuous and uninterrupted. The mounting holes and fixing method of the low-friction coated inclined plate to the rectangular support box 1 are exactly the same as those of the original inclined plate 4. It can be directly replaced and installed without changing the structure of the rectangular support box 1. The plate thickness and tilt angle are the same as the original parts, and it does not affect the positional correspondence with the rectangular through groove 2 or the trajectory of waste material falling. The coating is resistant to high and low temperatures and corrosion, and is suitable for the high-temperature waste environment after laser cutting. Its service life is longer than that of the original inclined plate. Maintenance only requires periodic cleaning of the coating surface. It is easy to operate and can be quickly adapted to the existing sticky waste separation production line.
