Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a self-positioning laser cutting machine. Background Technology

[0002] With the advancement of industry and intelligent manufacturing, laser cutting machines are evolving from traditional manual operation to full-process automation. Self-positioning laser cutting machines, by integrating visual sensing, dynamic control and intelligent algorithms, have significantly improved processing accuracy and production efficiency, especially in multi-variety, small-batch production scenarios, demonstrating strong advantages. However, existing equipment still faces efficiency and accuracy bottlenecks in the workpiece positioning process, which restricts the flexible production capabilities of the equipment. Developing adaptive mechanical structures to achieve fully automatic workpiece centering and clamping has become a key direction for the upgrading of laser cutting technology.

[0003] Existing laser cutting machines primarily consist of a laser generator, an optical system, a motion platform, and a clamping device. The laser generator produces a high-energy laser beam, which is focused by the optical system and then irradiates the workpiece surface. Cutting is achieved by melting or vaporizing the material using thermal energy. The motion platform is typically driven by a servo motor or stepper motor, moving the laser head or workpiece along a preset path. In current technology, workpiece positioning and clamping usually rely on manual operation or simple mechanical limiting devices, lacking automation and intelligent functionality.

[0004] Existing technologies have significant drawbacks in workpiece positioning. When processing workpieces of different specifications or shapes, frequent manual adjustments to mechanical limit devices or recalibration of the viewing distance reference point are required, resulting in excessively long debugging time per batch. Especially for materials with large thickness differences and low surface reflectivity, traditional vision positioning systems are easily affected by ambient light interference, leading to positioning errors and severely impacting the cutting yield. This problem directly restricts the equipment's response speed to multi-variety, small-batch orders, becoming an efficiency bottleneck for intelligent manufacturing production lines. To address this issue, a self-positioning laser cutting machine is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a self-positioning laser cutting machine, which aims to solve the problems of low production efficiency and insufficient positioning accuracy caused by the need for manual adjustment of the positioning device when processing multiple types of workpieces in existing laser cutting machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-positioning laser cutting machine includes a worktable, a laser cutting head disposed inside the worktable, a control panel fixedly connected to one side of the worktable, and a positioning component disposed inside the worktable for positioning the workpiece.

[0008] The positioning assembly includes a fixed frame, which is fixedly connected inside the worktable. A motor is fixedly connected to the bottom of the fixed frame, and a drive shaft is fixedly connected to the output end of the motor. Symmetrical slide rails are fixedly connected to the top of the fixed frame, and sliding frames are slidably connected to the outer walls of the slide rails. A first drive rod is rotatably connected to one side of the drive shaft, and one side of the first drive rod is rotatably connected to the bottom end of one of the sliding frames. A second drive rod is rotatably connected to the other side of the drive shaft, and one side of the second drive rod is rotatably connected to the bottom of the other sliding frame. Limit blocks are fixedly connected to the top of each sliding frame. A pusher assembly is provided inside the worktable for pushing the workpiece out.

[0009] As a further description of the above technical solution:

[0010] The pushing assembly includes a cylinder and a collecting box. The cylinder is fixedly connected inside the worktable, and the collecting box is slidably connected inside the worktable. A rubber plate is fixedly connected to the output end of the cylinder.

[0011] As a further description of the above technical solution:

[0012] The workbench has a sliding groove inside and multiple limiting grooves inside.

[0013] As a further description of the above technical solution:

[0014] The bottom of the collection box is fixedly connected with symmetrical connecting blocks, which slide inside the groove.

[0015] As a further description of the above technical solution:

[0016] A baffle is fixedly connected inside the connecting block, and springs are provided on both sides of the baffle.

[0017] As a further description of the above technical solution:

[0018] One end of each spring is fixedly connected to the side wall of the baffle, and the other end is fixedly connected to a compression block.

[0019] As a further description of the above technical solution:

[0020] A limiting ball is fixedly connected to one side of the extrusion block, and the limiting ball fits into the limiting groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the transmission shaft is driven to rotate by a motor. The rotation of the transmission shaft further drives the first and second transmission rods to deflect. The deflection of the first and second transmission rods drives the limiting block to move synchronously, thereby achieving the effect of quickly limiting workpieces of different sizes and maintaining their center position. This solves the problems of low production efficiency and insufficient positioning accuracy caused by manual adjustment of the positioning device in traditional laser cutting machines, and improves the stability of equipment operation.

[0023] 2. In this utility model, the processed workpiece is pushed into the collection box by a cylinder-driven rubber plate. The collection box collects the workpiece, and the collection box is stabilized by the cooperation of the limiting ball and the limiting groove, thereby achieving the effect of automatically collecting the processed workpiece. This solves the problems of time-consuming manual unloading and easy handling damage, and improves the working efficiency of the equipment. Attached Figure Description

[0032] 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.

[0033] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a self-positioning laser cutting machine, including a worktable 1, a laser cutting head 2 inside the worktable 1 for laser cutting of workpieces, a control panel 3 fixedly connected to one side of the worktable 1 for convenient and quick control of the equipment status by the user, and a positioning component inside the worktable 1 for positioning the workpiece.

[0034] The positioning component includes a fixed frame 4, which provides stable support and connection for the positioning component. The fixed frame 4 is fixedly connected inside the worktable 1. A motor 5 is fixedly connected to the bottom of the fixed frame 4, which provides core power to the component and ensures stable movement of the component. A drive shaft 6 is fixedly connected to the output end of the motor 5. A left-right symmetrical slide rail 9 is fixedly connected to the top of the fixed frame 4, which provides a sliding trajectory and ensures that the sliding frame 8 can slide stably. Sliding frames 8 are slidably connected to the outer walls of the slide rail 9. A drive rod 7 is rotatably connected to one side of the drive shaft 6. One side of the drive rod 7 is rotatably connected to the bottom end of one of the sliding frames 8. A drive rod 10 is rotatably connected to the other side of the drive shaft 6. One side of the drive rod 10 is rotatably connected to the bottom of another sliding frame 8, which is used to further transmit power and drive the movement of subsequent components. Limit blocks 11 are fixedly connected to the top of each sliding frame 8, which are used to contact the workpiece to ensure that the workpiece is always kept in a stable state and to adjust the position of the workpiece. A pusher component is provided inside the worktable 1, which is used to push the workpiece out.

[0035] Specifically, when high-precision laser cutting of workpieces of different sizes, shapes, or thicknesses is required, and manual adjustment of the positioning device is inefficient or inaccurate, the operator first monitors and operates the equipment status in real time through the control panel 3 to ensure that the equipment is always in a stable working state. The laser cutting head 2 is responsible for precisely cutting the workpiece, using the high temperature of the laser to perform efficient cutting on the workpiece. During the cutting process, the motor 5 drives the transmission shaft 6 to rotate through the output end. The rotation of the transmission shaft 6 further drives the transmission rod 7 and the transmission rod 10, generating a reverse deflection motion to ensure that the transmission rod 7 and the transmission rod 10 are in a stable working state. The second transmission rod 10 makes synchronous movements at the same time. This deflection movement is transmitted through the first transmission rod 7 and the second transmission rod 10, which further drives the two sliding frames 8 to slide smoothly along the outer wall of the slide rail 9, ensuring that the sliding frames 8 move on the predetermined trajectory. This ensures that the position of the workpiece remains stable during the cutting process. The movement of the sliding frames 8 also drives the limiting block 11 to move along the slide rail 9. The movement of the limiting block 11 ensures that the workpiece is accurately attached and in a stable centered state, realizing the self-positioning of the workpiece and avoiding the impact of positional deviation on the cutting accuracy, thus ensuring the stability and high quality of the processing.

[0036] Reference Figure 4 - Figure 6 The pushing assembly includes a cylinder 12 and a collection box 14, which are used to collect workpieces for convenient centralized processing by users. The cylinder 12 is fixedly connected inside the workbench 1, and the collection box 14 is slidably connected inside the workbench 1, which allows users to quickly place and remove the collection box 14. A rubber plate 13 is fixedly connected to the output end of the cylinder 12 for pushing the workpiece into contact with it, thereby pushing the workpiece into the collection box 14. A sliding groove 15 is provided inside the workbench 1, and multiple limiting grooves 16 are provided inside the workbench 1 for cooperation with other components to ensure the stability of the collection box 14 during collection. A left-right symmetrical connecting block 17 is fixedly connected to the bottom of the collection box 14, and the connecting block 17 slides inside the sliding groove 15.

[0037] Specifically, when it is necessary to achieve unmanned continuous production of laser cutting machines, shorten the production cycle, and avoid workpiece damage caused by manual unloading, the output end of the cylinder 12 pushes the rubber plate 13 to slide along the inside of the worktable 1, automatically pushing the processed workpiece into the collection box 14. The function of the collection box 14 is to collect the cut workpieces in a centralized manner, ensuring the cleanliness of the worktable 1 and the continuity of the production line. When it is necessary to clean the workpieces in the collection box 14, the operator can pull the collection box 14, using the pulling force to drive the connecting block 17 to slide in the slide groove 15. As the connecting block 17 slides, the limiting ball 21 generates friction with the inner wall of the worktable 1, forming a certain squeezing force.

[0038] Reference Figure 4 - Figure 6A baffle 18 is fixedly connected inside the connecting block 17 to provide extrusion force and ensure the stable deformation of the spring 19. Springs 19 are provided on both sides of the baffle 18 to provide stable elastic restoring force for the component and ensure that the component can quickly recover after movement. One end of each spring 19 is fixedly connected to the side wall of the baffle 18, and the other end is fixedly connected to an extrusion block 20. A limit ball 21 is fixedly connected to one side of the extrusion block 20. The limit ball 21 fits into the limit groove 16. Through the cooperation of the limit ball 21 and the limit groove 16, the collection box 14 is limited to a certain extent.

[0039] Specifically, further, this squeezing force forces the limiting ball 21 to press into the connecting block 17, thereby driving the spring 19 to undergo elastic deformation and store a certain amount of elastic potential energy. When the collection box 14 is reinstalled, the elastic restoring force of the spring 19 will push the limiting ball 21, causing it to lock into the limiting groove 16, thus playing an effective limiting role. This ensures that the collection box 14 remains stable during the material receiving process and prevents the collection box 14 from shifting its position, thereby making the workpiece collection process more automated and efficient, and providing a guarantee for the efficient operation of the cutting equipment.

[0040] Working Principle: When using this self-positioning laser cutting machine, the control panel 3 allows operators to easily monitor and control the equipment status in real time. The laser cutting head 2 performs laser cutting on the workpiece. During the cutting process, the output of the motor 5 drives the transmission shaft 6 to rotate. The rotation of the transmission shaft 6 drives the first transmission rod 7 and the second transmission rod 10 to simultaneously reverse their deflection motion. This deflection motion of the first and second transmission rods further pulls the two sliding frames 8, causing them to slide synchronously on the outer wall of the slide rail 9. The slide rail 9 ensures that the sliding frames 8 move along a pre-trajectory path. Simultaneously, the movement of the sliding frames 8 further drives the movement of the limiting block 11, causing it to engage with the workpiece and adjust its position, ensuring the workpiece is in a stable, centered state. This achieves the function of self-positioning the workpiece and ensuring its stability. To ensure stable processing, after processing is completed, the output end of cylinder 12 pushes rubber plate 13 to slide inside worktable 1, thereby pushing the processed workpiece into collection box 14. Collection box 14 collects the workpiece. When it is necessary to clean the workpiece inside collection box 14, the operator can directly pull collection box 14. The pulling force causes connecting block 17 to slide inside slide groove 15, causing limit ball 21 to rub against the inner wall of worktable 1 and generate extrusion force. The extrusion force further drives limit ball 21 to press into connecting block 17, thereby driving spring 19, causing spring 19 to undergo elastic deformation and store elastic potential energy. When installing collection box 14, the elastic restoring force of spring 19 pushes limit ball 21 into limit groove 16, thereby limiting collection box 14 and ensuring that collection box 14 remains stable when receiving materials.
