Description

Technical Field

[0001] This application relates to the field of cutting equipment, and more particularly to a laser cutting machine. Background Technology

[0002] The principle of a laser cutting machine is to focus the laser emitted from the laser emitter head into a high-power, high-density laser beam using an optical path system. The high-energy laser beam directly illuminates the surface of the workpiece, causing it to reach its melting point. Simultaneously, high-pressure gas coaxial with the laser emission blows away the molten or atomized metal.

[0003] In related technologies, workpieces are typically loaded and unloaded manually at the discharge port of laser cutting machines. The weight of the workpieces places a significant strain on the worker's physical strength, and prolonged working hours may lead to decreased productivity as the worker's stamina may not keep up with the speed of the laser cutting machine. Furthermore, the loading and unloading processes can easily pose safety hazards, making them highly dangerous. Summary of the Invention

[0004] To improve the safety of cutting workpieces using a laser cutting machine, this application provides a laser cutting machine.

[0005] The laser cutting machine provided in this application adopts the following technical solution: A laser cutting machine includes a first conveyor belt, a laser cutting machine body mounted on the upper part of the middle section of the first conveyor belt, a waste plate at the end of the first conveyor belt, a second conveyor belt below the first conveyor belt, the conveying direction of the first conveyor belt being perpendicular to the conveying direction of the second conveyor belt, a collection box at the end of the second conveyor belt, a support frame mounted on the second conveyor belt, a sliding plate slidably connected to the support frame, a driving component on the support frame for driving the sliding plate to slide only along the conveying direction parallel to the second conveyor belt, and a gripping mechanism for gripping workpieces on the first conveyor belt mounted on the sliding plate.

[0006] By adopting the above technical solution, the workpiece can be placed on the first conveyor belt, and then the workpiece can enter the cutting area of ​​the laser cutting machine body through the first conveyor belt. After the workpiece is cut by the laser cutting machine body, it can be grabbed by the gripping mechanism on the slide plate. Then, the drive component drives the slide plate to slide on the support, thereby moving the slide plate above the second conveyor belt. Then, the gripping mechanism releases the workpiece, allowing the workpiece to fall onto the second conveyor belt and be directly conveyed to the collection box through the second conveyor belt. At the same time, the waste generated by cutting can be conveyed to the waste plate through the first conveyor belt. This reduces the chance of people directly contacting the workpiece, greatly reducing the danger. Moreover, by performing cutting in a more automated way, the efficiency and capacity of workpiece production are improved, and the cutting efficiency of the workpiece is increased.

[0007] Optionally, the driving component is configured as an electric telescopic rod, the telescopic direction of which is parallel to the conveying direction of the second conveyor belt, the electric telescopic rod is mounted on the support frame and the end of the telescopic rod is fixedly connected to the slide plate.

[0008] By adopting the above technical solution, the sliding of the skateboard can be quickly and flexibly controlled by controlling the extension and retraction of the electric telescopic rod.

[0009] Optionally, the gripping mechanism includes a plurality of first hydraulic cylinders mounted on the slide plate, the extension and retraction direction of the first hydraulic cylinders being perpendicular to the end face of the slide plate, and the end of the piston rod of the first hydraulic cylinder passing through the slide plate and fixedly connected to a magnetic chuck.

[0010] By adopting the above technical solution, when the workpiece is made of a material that can be attracted by a magnetic chuck, the first hydraulic cylinder can be controlled to move the magnetic chuck to one side of the workpiece and attract the workpiece by the magnetic force of the magnetic chuck. After the workpiece is moved to the lowering position by the magnetic chuck, the magnetic chuck can be adjusted to release the magnetic chuck from attracting the workpiece.

[0011] Optionally, the gripping mechanism includes a second hydraulic cylinder. The extension and retraction direction of the second hydraulic cylinder is perpendicular to the end face of the slide plate. The end of the piston rod of the second hydraulic cylinder passes through the slide plate and is fixedly connected to a mounting plate. The mounting plate has a first locking belt and a second locking belt facing the first conveyor belt. The first locking belt has two sliding holes arranged along its length. The ends of the second locking belt pass through the sliding holes. Both the first and second locking belts have tightening components at their ends for tightening the first or second locking belt. A tensioning component is provided between the first locking belt and the edge of the mounting plate for moving the first locking belt toward the edge of the mounting plate. The second locking belt has the same tensioning component at its edge and the edge of the mounting plate.

[0012] By adopting the above technical solution, when adsorbing a non-magnetic workpiece, the second hydraulic cylinder can be adjusted to move the mounting plate towards one side of the workpiece, thereby placing the workpiece between the first and second locking belts. Then, the tightening assembly is adjusted to tighten the first and second locking belts, thus securing them to the workpiece and fixing it to the mounting plate. The workpiece can then be transported along with the mounting plate. After the workpiece reaches the top of the second conveyor belt, the tightening assembly is adjusted to tighten the first and second locking belts. Under the action of the tensioning assembly, the first and second locking belts can be brought closer to the edge of the mounting plate, facilitating the fixing of the next workpiece by the first and second locking belts.

[0013] Optionally, the tightening assembly includes a mounting housing fixedly connected to the mounting plate. A rotating wheel is rotatably connected inside the mounting housing. One end of the first locking strap or one end of the second locking strap is fixedly connected to the arc-shaped sidewall of the rotating wheel. A drive motor for driving the rotating wheel to rotate is mounted on the mounting housing. The drive motor is fixedly connected to the mounting housing, and the output shaft of the drive motor passes through the mounting housing and is connected to the shaft of the rotating wheel.

[0014] By adopting the above technical solution, the rotating wheel can be driven by the drive motor to rotate, thereby causing the first or second locking belt to wrap around the rotating wheel, and thus quickly tightening the first or second locking belt.

[0015] Optionally, the tensioning assembly includes a plurality of springs, one end of which is fixed to the edge of the mounting plate, and the other end of which is fixed to the first or second locking band, the springs applying a force toward the edge of the mounting plate to the first or second locking band.

[0016] By adopting the above technical solution, when the first and second locking bands are tightened, the spring can be stretched. When the first and second locking bands are untightened, the spring force can quickly move the first and second locking bands towards the edge of the mounting plate, thereby facilitating the entry of the next workpiece into the area between the first and second locking bands.

[0017] Optionally, a mounting hole is provided in the middle section of the first locking band. The mounting hole is arranged along the length direction of the first locking band. A plurality of rubber posts are fixedly connected in the mounting hole. The rubber posts are arranged along the length direction of the mounting hole, and the axis of the rubber posts is perpendicular to the opening direction of the mounting hole. By adopting the above technical solution, the friction between the first locking band and the workpiece can be increased by using the rubber column.

[0018] Optionally, a plurality of elastic balls are fixedly connected to the arc-shaped sidewall of the rubber column, the elastic balls being arranged along the length direction of the rubber column, and a plurality of locking teeth are fixedly connected to the arc-shaped sidewall of the elastic balls.

[0019] By adopting the above technical solution, when the workpiece is locked by the first locking belt and the workpiece is irregular, the elastic ball can be compressed, and the locking teeth on the elastic ball can be embedded in the irregular workpiece, thereby improving the locking effect of the locking teeth on the workpiece.

[0020] Optionally, a groove is provided on the side wall of the elastic ball opposite to the locking tooth on the side away from the rubber column, and a rubber sealing block is fixedly connected to the groove opening, and the locking tooth on the side away from the rubber column is fixedly connected to the rubber sealing block.

[0021] By adopting the above technical solution, when the locking tooth on the side away from the rubber column abuts against the workpiece surface, the locking tooth can apply external force to the rubber sealing block, causing the rubber sealing block to move the locking tooth into the groove. This causes the locking teeth on both sides of the rubber sealing block to move closer to the groove and abut against the workpiece, or increase the contact area with the workpiece, thereby improving the contact effect of the locking teeth on both sides of the rubber sealing block against the workpiece.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The sliding plate is driven by the drive component to slide on the support, thereby moving the sliding plate above the second conveyor belt. Then, the gripping mechanism releases the workpiece from the fixation, allowing the workpiece to fall onto the second conveyor belt and be directly conveyed to the collection box. At the same time, the waste generated during cutting can be conveyed to the waste plate through the first conveyor belt. This reduces the chance of people directly contacting the workpiece, greatly reducing the danger. Furthermore, the cutting is carried out in a more automated way, which improves the efficiency and capacity of workpiece production and increases the cutting efficiency of the workpiece. 2. When the workpiece is made of a material that can be attracted by a magnetic chuck, the first hydraulic cylinder can be controlled to move the magnetic chuck toward the workpiece and attract the workpiece by the magnetic force of the magnetic chuck. After the workpiece is moved to the lowering position by the magnetic chuck, the magnetic chuck can be adjusted to release the magnetic chuck from attracting the workpiece. 3. When adsorbing a non-magnetic workpiece, the second hydraulic cylinder can be adjusted to move the mounting plate to one side of the workpiece, thereby placing the workpiece between the first and second locking straps. Then, the tightening assembly is adjusted to tighten the first and second locking straps, thereby securing the workpiece to the mounting plate. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1 A laser cutting machine, as shown in the reference Figure 1 The system includes a first conveyor belt 1 erected on the ground. A laser cutting machine body 3 is located in the middle section along the length of the first conveyor belt 1, and the laser cutting machine body 3 is mounted on the upper surface of the first conveyor belt 1. A waste plate 4 is located at the end of the first conveyor belt 1. A second conveyor belt 2 is located below the first conveyor belt 1, and the second conveyor belt 2 is erected on the ground. The conveying direction of the first conveyor belt 1 is perpendicular to the conveying direction of the second conveyor belt 2. A collection box 5 is located at the end of the second conveyor belt 2.

[0027] A support frame 6 is mounted on the second conveyor belt 2, positioned above the first conveyor belt 1. A slide plate 61 is slidably connected to the upper end of the support frame 6. A driving component 62 is provided on the support frame 6 to drive the slide plate 61 to slide on the support frame 6. In this embodiment, the driving component 62 is an electric telescopic rod, which is mounted on the support frame 6. The telescopic direction of the electric telescopic rod is parallel to the conveying direction of the second conveyor belt 2, and the telescopic end of the electric telescopic rod is fixedly connected to the side wall of the slide plate 61.

[0028] This activates the electric telescopic rod, which drives the slide plate 61 to slide on the support frame 6, with the sliding direction parallel to the conveying direction of the second conveyor belt 2.

[0029] A gripping mechanism 7 for gripping workpieces on the first conveyor belt 1 is installed on the slide plate 61. The gripping mechanism 7 includes two first hydraulic cylinders 71, which are mounted on the upper end face of the slide plate 61. The extension and retraction direction of the first hydraulic cylinders 71 is perpendicular to the end face of the slide plate 61. The end of the piston rod of the first hydraulic cylinder 71 passes through the slide plate 61 and is fixedly connected to a magnetic chuck 72.

[0030] The implementation principle of Example 1 is as follows: When the workpiece is made of a material that can be attracted by the magnetic chuck 72, the workpiece can be placed on the first conveyor belt 1. Then, the workpiece can enter the cutting area of ​​the laser cutting machine body 3 through the first conveyor belt 1, so that the laser cutting machine body 3 can cut the workpiece. After the workpiece is cut, the first hydraulic cylinder 71 can be activated to drive the magnetic chuck 72 to move to one side of the workpiece and attract the workpiece onto the magnetic chuck 72. Then, by activating the electric telescopic rod, the electric telescopic rod can drive the slide plate 61 to slide on the support and move the slide plate 61 above the second conveyor belt. Then, the magnetic chuck 72 is adjusted so that the magnetic chuck 72 can release the fixation of the workpiece, so that the workpiece falls onto the second conveyor belt 2 and is directly conveyed to the collection box 5 through the second conveyor belt 2. At the same time, the waste generated by cutting can be conveyed to the waste plate 4 through the first conveyor belt 1.

[0031] Example 2 The difference from Example 1 is that: (Refer to...) Figure 2 and Figure 3 The gripping mechanism 7 includes two second hydraulic cylinders 73. The second hydraulic cylinders 73 are mounted on the upper end surface of the slide plate 61 and the extension and retraction direction of the second hydraulic cylinders 73 is perpendicular to the upper end surface of the slide plate 61. The end of the piston rod of the second hydraulic cylinder 73 passes through the slide plate 61 and is fixedly connected to the same mounting plate 74.

[0032] The mounting plate 74 is a rectangular frame. A first locking band 75 and a second locking band 76 are provided on the side of the mounting plate 74 facing the first conveyor belt 1. Two sliding holes 751 are provided on the first locking band 75, located at both ends of the first locking band 75. The sliding holes 751 are arranged along the length of the first locking band 75. The ends of the second locking band 76 pass through the sliding holes 751. Each end of the first locking band 75 and the second locking band 76 is provided with a tightening component 77 for tightening the first locking band 75 or the second locking band 76. Four tightening components 77 are provided, located at the ends of the first locking band 75 and the second locking band 76, respectively.

[0033] Reference Figure 3 and Figure 4The tightening assembly 77 includes a mounting housing 771, which is fixedly connected to the mounting plate 74 and has its opening facing the mounting frame. A rotating wheel 772 is rotatably connected inside the mounting housing 771. One end of the first locking strap 75 or one end of the second locking strap 76 passes through the side wall of the mounting plate 74 and is fixedly connected to the arc-shaped side wall of the rotating wheel 772. A drive motor 773 is mounted on the upper end of the mounting housing 771 and is fixedly connected to the mounting housing 771. The output shaft of the drive motor 773 is coaxially arranged with the rotating wheel 772 and passes through the mounting housing 771 and is fixedly connected to the rotating wheel 772.

[0034] Thus, the rotating wheel 772 can be rotated by the drive motor 773, thereby causing the first locking belt 75 or the second locking belt 76 to wrap around the rotating wheel 772 and tighten the first locking belt 75 or the second locking belt 76, thereby pressing the workpiece between the first locking belt 75 and the second locking belt 76, thereby fixing the workpiece on the mounting plate 74.

[0035] Alternatively, the drive motor 773 can be controlled to rotate the rotating wheel 772 in another direction, thereby causing the first locking belt 75 or the second locking belt 76 to release its tightening on the rotating wheel 772, and thus causing the workpiece to be released from its fixation on the mounting plate 74.

[0036] To facilitate the entry of the next workpiece between the first locking band 75 and the second locking band 76, a tensioning assembly 78 is provided between the first locking band 75 and the edge of the mounting plate 74 for moving the first locking band 75 toward the edge of the mounting plate 74.

[0037] The tensioning assembly 78 includes multiple springs 781 arranged along the length of the first locking band 75. One end of each spring 781 is fixedly connected to the first locking band, and the other end is fixedly connected to the inner wall of the mounting plate 74. In the figure, the springs 781 are in a contracted state. The second locking band 76 and the edge of the mounting plate 74 are provided with the same tensioning assembly 78.

[0038] Therefore, when the rotating wheel 772 releases the tension on the first locking band 75, the spring 781 can drive the first locking band 75 to move towards the edge of the mounting plate 74, leaving space for the workpiece to enter between the first locking bands 75.

[0039] Reference Figure 3 and Figure 5 The first locking band 75 has a mounting hole 752 in its middle section, which is located between two sliding holes 751. The mounting hole 752 is provided along the length of the first locking band 75, and the second locking band 76 has the same mounting hole 752.

[0040] Multiple rubber posts 753 are fixedly connected within the mounting hole 752. The rubber posts 753 are equidistantly arranged along the length of the mounting hole 752, and the axis of the rubber posts 753 is perpendicular to the opening direction of the mounting hole 752. Multiple elastic balls 755 are fixedly connected to the arc-shaped sidewall of the rubber post 753. The elastic balls 755 are equidistantly arranged along the length of the rubber post 753, and the elastic balls 755 are located on the side of the rubber post 753 away from the edge of the mounting plate 74.

[0041] To improve the locking effect of the rubber pillar 753 on the workpiece, three locking teeth 754 are fixed on the arc-shaped sidewall of each elastic ball 755. The locking teeth 754 are arranged along the arc surface of the elastic ball 755. The sidewall of the elastic ball 755 opposite to the locking tooth 754 of the side away from the rubber pillar 753 has a groove 7551, which is set as a V-shaped groove. A rubber sealing block 7552 is fixedly connected to the groove opening of the groove 7551, and the locking tooth 754 of the side away from the rubber pillar 753 is fixedly connected to the rubber sealing block 7552.

[0042] The implementation principle of this application embodiment is as follows: When adsorbing a non-magnetic workpiece, the second hydraulic cylinder 73 is adjusted to move the mounting plate 74 towards the workpiece. The workpiece is then placed between the first locking band 75 and the second locking band 76. The drive motor 773 is then activated, causing the rotating wheel 772 to tighten the first locking band 75 and the second locking band 76, thereby securing them tightly to the workpiece. Simultaneously, the multiple elastic balls 755 on the rubber column 753 press against the workpiece. Simultaneously, the elastic ball 755 is compressed, and the locking teeth 754 on the elastic ball 755 can be embedded into the irregular workpiece, thereby locking the workpiece onto the mounting plate 74. Subsequently, when the mounting plate 74 is placed above the second conveyor belt 2, the drive motor 773 is controlled to rotate, causing the rotating wheel 772 to release the tightening of the first locking belt 75 and the second locking belt 76. Then, under the action of the spring 781, the first locking belt 75 and the second locking belt 76 can be moved closer to the edge of the mounting plate 74, thereby releasing the workpiece from the fixing on the mounting plate 74 and causing the workpiece to fall onto the second conveyor belt 2.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
