Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, specifically referring to a laser cutting device. Background Technology

[0002] In the field of mechanical parts manufacturing, laser cutting technology has become one of the core processes of precision manufacturing due to its high precision, non-contact processing, and minimal thermal deformation. Its advantages are significant in complex surface machining and micro-aperture machining, leading to its widespread application in high-end fields such as aerospace, automotive manufacturing, and precision instruments. However, as the manufacturing industry moves towards intelligent and automated processes, existing equipment is gradually revealing multi-dimensional technical bottlenecks in practical applications.

[0003] A stage provides a platform for cutting workpieces. The gaps on the stage surface are smaller than the workpiece size to prevent the workpiece from falling off. However, after cutting, the parts and waste remain on the stage, requiring removal, which is inconvenient. Current laser cutting equipment often uses a hollowed-out stage design to avoid burns and melting of the stage surface by excess laser light. This typically employs strip-shaped or dot-matrix supports, significantly reducing the contact area with the workpiece and minimizing stress concentration at contact points. However, a hollowed-out stage increases the difficulty of unloading the cut parts, as they may get stuck between the hollow support strips or dot matrix during unloading. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a laser cutting device with a dynamically hollowed-out worktable, which facilitates both laser cutting and automatic unloading after cutting.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a laser cutting equipment, including a frame, a dynamic hollowing worktable and a laser device are provided in the frame, the laser device is slidably disposed above the dynamic hollowing worktable, a plate clamping and lifting mechanism is provided at the rear of the dynamic hollowing worktable, a pushing mechanism is provided on one side of the dynamic hollowing worktable, and a receiving hopper is provided on the side of the dynamic hollowing worktable away from the pushing mechanism. The dynamic hollowing worktable includes a base, support columns, a tabletop filler, and a self-locking multi-directional rotation drive for rotating the tabletop filler. The base is embedded in the frame and has a cavity with an opening in the upper wall. The support columns are arranged in a rectangular array within the cavity, forming multiple rows along the length of the cavity and multiple columns along the width of the cavity. The tabletop filler is rotatably positioned between two adjacent rows of support columns. Symmetrical storage cavities are provided on both sides of the cavity, and the storage cavities are connected to the cavity. The self-locking multi-directional rotation drive is located within the storage cavity and connected to the tabletop filler.

[0006] The self-locking multi-directional rotation drive includes a multi-directional rotation mechanism, a first steering drive, and a second self-locking steering drive. Each multi-directional rotation mechanism corresponds to a tabletop filling component and is located within the storage cavity. These multi-directional rotation mechanisms are equidistantly distributed along the X-axis direction, i.e., along the length of the storage cavity. The first steering drive and the second self-locking steering drive are located on the sidewall of the platform. The multi-directional rotation mechanism includes a steering ball, a steering column, and a first rotating frame. The steering column rotatably penetrates the sidewall of the platform. The first rotating frame is L-shaped, with one end of its outer wall fixed to the steering column and the other end of its inner wall provided with a steering slide shaft. The steering ball's sidewall is radially provided with a first rotating shaft. The first rotating shaft is rotatably connected to the second self-locking steering drive, and the steering ball is rotatably mounted on the second self-locking steering drive via the first rotating shaft. The surface of the steering ball is provided with an arc-shaped groove along the circumference. The axis of the arc-shaped groove is perpendicular to the axis of the first rotating shaft and the axis of the steering shaft, and intersects the center of the steering ball. The steering ball rotates around the X-axis and the Y-axis, which are perpendicular to each other and intersect at the center of the steering ball. The steering column is coaxial with the Y-axis, and the steering slide is coaxial with the X-axis. The steering slide is slidably locked in the arc-shaped groove. The first steering drive is connected to the steering column, and the platform filler is located at the end of the first rotating shaft.

[0007] Preferably, the second self-locking steering drive includes a second rotating frame, transmission gears, a self-locking motor, a self-locking worm gear, and a self-locking worm. The second rotating frame is U-shaped, and a second rotating shaft is fixedly connected to both ends of the second rotating frame. The second rotating shaft rotatably passes through the side wall of the platform. The axis of the second rotating shaft is coaxial with the X-axis and perpendicular to the first rotating shaft. There are at least two transmission gears, which mesh sequentially and are rotatably mounted on the side wall of the platform. The second rotating shaft is coaxially fixed to one of the transmission gears. The self-locking worm gear is coaxially fixed to the side wall of another transmission gear. The self-locking worm is rotatably mounted on the side wall of the platform and meshes with the self-locking worm gear. The self-locking motor is located on the side wall of the platform, and its output end is connected to the self-locking worm.

[0008] The self-locking motor drives the self-locking worm gear to rotate, which in turn drives the self-locking worm wheel to rotate. The self-locking worm wheel drives the second rotating shaft to rotate through multiple sequentially meshing transmission gears. The second rotating shaft drives the second rotating frame to rotate, and the axis of rotation of the second rotating frame coincides with the center of the steering ball. The second rotating frame drives the first rotating shaft and the tabletop filler to rotate around the X-axis of the steering ball (i.e., the axis of the second rotating shaft). The first steering drive drives the steering ball to rotate around the Y-axis through the steering column, and the steering ball drives the tabletop filler to rotate around the Y-axis.

[0009] Preferably, the tabletop filler includes a horizontal plate and a vertical plate disposed on one side of the horizontal plate. The vertical plates are equidistantly distributed along the length of the horizontal plate. The distance between two adjacent horizontal plates is equal to the distance between two adjacent vertical plates. Two adjacent horizontal plates and two adjacent vertical plates form a square receiving hole, and the support column is disposed in the receiving hole.

[0010] More specifically, the first steering drive includes a steering gear, a steering rack, and a steering electric actuator. The steering gear is rotatably mounted on the side wall of the base and is coaxially fixed to the steering column. The steering rack is slidably mounted on the side wall of the base. The steering electric actuator is mounted on the side wall of the base, and its output end is connected to the steering rack.

[0011] The plate clamping and lifting mechanism includes a lifting cylinder, a lifting seat, a clamping double-acting screw, a clamping slide, a clamping bracket, and clamping components. The lifting cylinder is located at the bottom of the frame, and the lifting seat is located above the lifting cylinder. The lifting seat has a clamping groove along its length. The clamping double-acting screw is rotatably mounted in the clamping groove, and the clamping slides are symmetrically slidably mounted in the clamping groove. The two symmetrically mounted clamping slides are threaded to both ends of the clamping double-acting screw. The side wall of the lifting seat is equipped with a clamping motor that drives the clamping double-acting screw to rotate. The output end of the clamping motor is connected to the clamping double-acting screw. The clamping bracket is located on the clamping slide and is arranged in an inverted L-shape. The clamping components are located at the bottom of the clamping bracket and are arranged opposite each other. The lifting cylinder is an electric cylinder.

[0012] The clamping motor drives the clamping bidirectional lead screw to rotate, which in turn drives two symmetrically arranged clamping slides to move towards each other or away from each other, thereby causing the two clamping components to move closer or further apart. This facilitates the clamping and fixing of plates of different sizes to be cut. The lifting cylinder extends and moves the lifting seat upward, thereby moving the plate clamped by the clamping components upward away from the dynamic hollowing worktable, making it easier to separate the cut parts from the plate.

[0013] Furthermore, the pushing mechanism includes a pushing seat, multiple sets of scissor arm assemblies, and a pushing plate connected in sequence. The pushing seat has a storage slot for storing the scissor arm assembly on its side wall facing the pushing plate. One end of the scissor arm assembly is installed in the storage slot, and the other end of the scissor arm assembly is connected to the side wall of the pushing plate facing the pushing seat. The inner wall of the storage slot and the side wall of the pushing plate are respectively provided with guide rails. The four ends of the scissor arm assembly are respectively hinged with sliders adapted to the guide rails. The sliders are slidably connected in pairs to the guide rails on the inner wall of the storage slot and the guide rails on the side wall of the pushing plate. The multiple sets of scissor arm assemblies are connected end to end by hinges. Each scissor arm assembly includes two scissor bars with the same structure. The two scissor bars are crossed and hinged at the midpoint to form an X-shaped structure, thereby forming a continuous telescopic frame.

[0014] Preferably, a bidirectional pusher screw is rotatably installed inside the storage slot, a pusher motor is provided on the side wall of the pusher seat, and two sliders that are slidably connected to the guide rail on the inner wall of the storage slot are respectively threaded to both ends of the bidirectional pusher screw.

[0015] The pusher motor drives the pusher double screw to rotate. The pusher double screw drives two sliders that are slidably connected to the guide rail on the inner wall of the storage tank to slide and approach synchronously along the guide rail, thereby driving the scissor bar to rotate. This causes multiple sets of scissor arms to extend synchronously, which in turn drives the pusher plate to slide along the table surface of the dynamic hollow worktable to push the cut parts into the receiving hopper.

[0016] More specifically, the laser device includes a laser head, a gantry frame, a Y-axis drive module, and an X-axis drive module. The Y-axis drive module is symmetrically arranged on both sides of the frame. The gantry frame is mounted on the Y-axis drive module and erected above the dynamic hollowing worktable. The X-axis drive module is mounted on the gantry frame, and the laser head is mounted on the X-axis drive module.

[0017] Preferably, the frame is provided with an electrical control box, and the electrical control box is provided with a controller. The controller is electrically connected to the pusher motor, the clamping motor, the lifting cylinder, the laser head, the Y-axis drive module, the X-axis drive module, the self-locking motor, and the steering electric push rod.

[0018] Preferably, the first steering drive is provided with a cover on the outside, the platform sidewall is provided with a self-locking drive cavity, the transmission gear, the self-locking worm gear and the self-locking worm are provided in the self-locking drive cavity, and the self-locking worm rotates through the self-locking drive cavity.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows: 1. To address the core issues of existing hollowed-out worktables where parts easily get stuck after cutting and manual material handling is inconvenient, a dynamically switching worktable is designed. The worktable can switch between hollowed-out cutting and flat material handling by rotating the worktable filler. During cutting, the worktable is kept in a hollowed-out state to reduce burns, while during material handling, it switches to a near-flat state. This solves the problem of reducing burns during hollowed-out worktable cutting and avoids the pain point of parts getting stuck during material handling, achieving complementary functions.

[0020] 2. The plate clamping and lifting mechanism achieves adjustable clamping distance through a two-way lead screw, which can adapt to different sizes of plates to be cut without the need to change special fixtures; the pushing mechanism adopts a scissor arm telescopic design, which can adapt to worktables of different lengths and is compatible with the pushing of various specifications of parts, making it highly versatile.

[0021] 3. The bidirectional rotation of the table filler is achieved through a self-locking multi-directional rotation drive. The steering ball, as the core transmission component, works with the arc-shaped slide groove and steering shaft to ensure accurate rotation trajectory. The self-locking worm and self-locking worm wheel have self-locking functions, which can stably fix the position of the table filler and prevent the table from shifting during cutting or pushing.

[0022] 4. The material feeding mechanism enables automated feeding, replacing manual operation and reducing the time for picking up and placing parts. It is especially suitable for mass production, which can significantly increase the processing volume per unit time and shorten the process interval. Attached Figure Description

[0031] In some embodiments, a pressure sensor may be provided on the sidewall of the clamping member 45 to detect whether the clamping is secure.

[0032] like Figures 3-10 As shown, the self-locking multi-directional rotation drive 10 includes a multi-directional rotation mechanism 13, a first steering drive 14, and a second self-locking steering drive 15. The multi-directional rotation mechanism 13 corresponds one-to-one with the tabletop filling member 9.

A steering ball 16 is rotatably mounted on the second self-locking steering drive 15 via the first rotating shaft 20. The surface of the steering ball 16 is provided with an arc-shaped groove 21 along its circumference. The axis of the arc-shaped groove 21 is perpendicular to the axis of the first rotating shaft 20 and the axis of the steering slide shaft 19, and intersects at the center of the steering ball 16.

[0033] The second self-locking steering drive 15 includes a second rotating frame 22, a transmission gear 23, a self-locking motor 24, a self-locking worm gear 25, and a self-locking worm 26. The second rotating frame 22 is U-shaped, and a second rotating shaft 27 is fixedly connected to both ends of the second rotating frame 22. The second rotating shaft 27 rotatably passes through the side wall of the base 7. The axis of the second rotating shaft 27 is coaxial with the X-axis. The second rotating shaft 27 is perpendicular to the first rotating shaft 20. There are at least two transmission gears 23, which mesh sequentially and are rotatably mounted on the side wall of the base 7. The second rotating shaft 27 is coaxially fixedly connected to one of the transmission gears 23. The self-locking worm gear 25 is coaxially fixedly connected to the side wall of another transmission gear 23.

[0037] like Figure 1 , Figure 3 , Figure 13 and Figure 14 As shown, the pushing mechanism 5 includes a pushing seat 48, multiple sets of scissor arm assemblies 49, and a pushing plate 50 connected in sequence. The pushing seat 48 has a storage slot 51 on its side wall facing the pushing plate 50 for storing the scissor arm assemblies 49. One end of each scissor arm assembly 49 is installed in the storage slot 51, and the other end is connected to the side wall of the pushing plate 50 facing the pushing seat 48. Guide rails are provided on the inner wall of the storage slot 51 and the side wall of the pushing plate 50. 52. The four ends of the scissor arm assembly 49 are respectively hinged with sliders 53 adapted to the guide rails 52. The sliders 53 are slidably connected in pairs to the guide rails 52 on the inner wall of the storage groove 51 and the guide rails 52 on the side wall of the pusher plate 50. Multiple scissor arm assemblies 49 are connected end to end in sequence. The scissor arm assembly 49 includes two scissor rods 54 with the same structure. The two scissor rods 54 are cross-hinged at the midpoint to form an X-shaped structure, thereby forming a continuous telescopic frame.

[0038] The storage slot 51 is rotatably connected to a bidirectional pusher screw 55, and the pusher seat 48 is provided with a pusher motor 56 on its side wall. Two sliders 53 that are slidably connected to the guide rail 52 on the inner wall of the storage slot 51 are respectively threaded to both ends of the bidirectional pusher screw 55.

[0039] The frame 1 is equipped with an electrical control box 57, which contains a controller. The controller is electrically connected to the pusher motor 56, the clamping motor 47, the lifting cylinder 40, the laser head 36, the Y-axis drive module 38, the X-axis drive module 39, the self-locking motor 24, and the steering electric push rod 30.

[0040] In practical use, the material to be processed is first placed on the dynamic hollowing worktable 2. Then, the clamping motor 47 is started. Initially, the clamping parts 45 are located on both sides of the dynamic hollowing worktable 2, and the bottom wall of the clamping parts 45 is in contact with the upper wall of the dynamic hollowing worktable 2. The clamping motor 47 drives the clamping bidirectional lead screw 42 to rotate. The clamping bidirectional lead screw 42 drives the two symmetrically arranged clamping slides 43 to move towards each other, thereby driving the two clamping parts 45 to move closer to each other to clamp and fix the material. Then, the laser device 3 is started, and the laser head 36 is moved through the Y-axis drive module 38 and the X-axis drive module 39 to cut multiple parts on the material. After cutting, the laser head 36 is turned off, and the laser head 36 is moved away from the dynamic hollowing worktable 2 through the Y-axis drive module 38 and the X-axis drive module 39. Initially, as Figure 11 As shown, the tabletop filler 9 is vertically positioned downwards within the storage cavity 12. Then, the self-locking motor 24 is activated, driving the self-locking worm gear 26 to rotate. The self-locking worm gear 26 drives the self-locking worm wheel 25 to rotate. The self-locking worm wheel 25, through multiple sequentially meshing transmission gears 23, drives the second rotating shaft 27 to rotate. The second rotating shaft 27 drives the second rotating frame 22 to rotate, with the axis of rotation of the second rotating frame 22 coinciding with the center of the steering ball 16. The second rotating frame 22 drives the first rotating shaft 20 and the tabletop filler 9 to rotate upwards by 90° around the X-axis of the steering ball 16. At this point, the tabletop filler 9 is horizontally positioned with its vertical plate... 34 is located below the horizontal plate 33. Then, the steering electric actuator 30 is extended to move the steering rack 29. The steering rack 29 drives the steering gear 28 to rotate. The steering gear 28 drives the first rotating frame 18 to rotate through the steering column 17. The first rotating frame 18 drives the steering ball 16 to rotate 90° around the Y-axis through the steering sliding shaft 19 and the arc-shaped sliding groove 21. The steering ball 16 drives the table filler 9 to rotate 90° around the Y-axis through the first rotating shaft 20. At this time, the longitudinal plate 34 rotates from below the horizontal plate 33 to one side of the horizontal plate 33 and is inserted between the two adjacent rows of support columns 8. The state of the table filler 9 is as follows. Figure 4 and Figure 5As shown, the horizontal plate 33 and the vertical plate 34 fill the gap between the support column 8, making the surface of the dynamic hollowing worktable 2 approximately flat, facilitating the pushing of parts and reducing the chance of parts getting stuck; then the lifting cylinder 40 is activated, the lifting cylinder 40 extends and drives the lifting seat 41 to move upward, the lifting seat 41 drives the plate held by the clamping bracket 44 and the clamping member 45 to move upward, away from the dynamic hollowing worktable 2, so that the cut part separates from the plate, and the cut part falls on the dynamic hollowing worktable 2, then the... The pusher mechanism 5 is activated by a pusher motor 56, which drives a bidirectional pusher screw 55 to rotate. The bidirectional pusher screw 55 drives two sliders 53, which are slidably connected to the guide rail 52 on the inner wall of the storage trough 51, to slide synchronously along the guide rail 52 and approach each other. This causes the scissor bar 54 to rotate, resulting in the synchronous extension of multiple scissor arm assemblies 49. This, in turn, causes the pusher plate 50 to slide along the surface of the dynamic hollow worktable 2 to push the cut parts into the receiving hopper 6. After the pushing is completed, the pusher motor 56 is reversed, causing the two sliders 53 to reset. This causes multiple sets of scissor arms 49 to retract and retract into the storage slot 51. The multiple sets of scissor arms 49 drive the pusher plate 50 to move in the opposite direction and reset. Then, the lifting cylinder 40 is controlled to retract, causing the clamping bracket 44 and clamping member 45 to move down and reset, so that the bottom wall of the clamping member 45 is in contact with the upper wall of the dynamic hollow worktable 2. The clamping motor 47 is controlled to reverse, causing the clamping bidirectional screw 42 to reverse and drive the two symmetrically arranged clamping slides 43 to move in the opposite direction and separate. The clamping slides 43 drive the clamping bracket 44 and clamping member 45 to move in the opposite direction and separate. Move the components to opposite sides of the dynamic hollow worktable 2, then control the steering electric push rod 30 to retract and drive the steering rack 29 to move in the opposite direction. This causes the steering rack 29 to drive the steering ball 16 and the table filler 9 to rotate 90° downward around the Y-axis and reset. Then control the self-locking motor 24 to reverse, and drive the steering ball 16 and the table filler 9 to rotate 90° downward around the X-axis and reset them in the storage cavity 12 through the second self-locking steering drive 15. Repeat the above operation to complete the processing of multiple boards.
