Description
Technical Field
[0001] This invention relates to the field of laser welding technology, specifically to a semi-automatic laser cutting machine. Background Technology
[0002] As one of the core processes in modern materials processing, laser cutting technology has undergone a leapfrog development from laboratory research to large-scale industrial application since the first ruby laser was invented in the 1960s. In 1964, Bell Labs in the United States successfully developed the world's first carbon dioxide gas laser, which applied focused laser energy to material cutting for the first time, marking the formal entry of laser cutting technology into the industrial field. Since then, with the improvement of laser power and the optimization of beam quality, laser cutting has gradually broken through the processing boundaries of metal and non-metal materials, becoming a key technology support for industries such as aerospace, automobile manufacturing, and precision electronics.
[0003] In the current field of laser cutting, many limitations remain insurmountable when facing complex and ever-changing cutting needs, especially when dealing with thick materials. Traditional laser cutting machines are particularly problematic in this regard. Traditional equipment typically uses only a single laser cutting head, and the cutting method is limited to a vertical downward movement from above the material. As the laser penetrates thicker materials, it encounters significant resistance and energy loss. With increasing cutting depth, the laser energy decreases sharply, making it difficult to sustain sufficient energy for efficient cutting. This often results in the inability to complete the cutting task smoothly in one pass when cutting thicker materials, requiring multiple repeated cutting operations, greatly reducing cutting efficiency. Furthermore, the high heat generated by the laser interacts with the assist gas during cutting, creating complex effects on the cut surface. The high heat causes rapid localized softening of the material, while the assist gas, while removing molten slag, also affects the cut surface. When a certain force is applied to the surface, this combined effect can easily cause the cut surface of the workpiece to collapse and deform downwards. The deformed cut surface not only seriously affects the dimensional accuracy and surface quality of the cut part, making it difficult to meet the requirements of high-precision processing, but also brings many inconveniences and potential problems in subsequent assembly and use. In order to correct this deformation, it is usually necessary to add grinding, straightening and other processes, which not only increases production costs, but also prolongs the production cycle and reduces the overall production efficiency. In terms of laser energy utilization, traditional laser cutting equipment also has obvious shortcomings. The light generated during laser cutting is like a disordered beam, scattering in all directions. A large amount of laser energy is wasted in the scattering process and cannot be concentrated on the cutting part. This not only directly leads to a significant reduction in cutting efficiency, reducing the amount of cutting work that can be completed per unit time, but the scattered laser may also have adverse effects on the surrounding environment.

[0014] Furthermore, a side main block is provided on one side surface of the sliding support rod, and a connecting plug is provided on the side surface of the side main block opposite to the sliding support rod.

[0015] Furthermore, sliding blocks are provided on both sides of the upper surface of the bottom support plate, and force-bearing side plates are provided on the upper surface of the sliding blocks.

A bottom motor is provided on the bottom surface of the worktable, and a bottom engaging rod is provided at the end of the output shaft of the bottom motor. The bottom engaging rod engages with the engaging hole at the center of the bottom engaging block.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. In this solution, by setting up a side frame component, the internal motor drives the dual-axis screw to move the meshing plate, thereby realizing the precise scooping, rotation and clamping operation of the long storage box for thicker cutting materials. During the rotation, the long storage box cooperates with the support movable bar and the weight block to automatically release the restriction on the internal rotating plate, realizing the automatic storage of the movable scoop block. At the same time, the clamping side plate and the anti-slip buffer plate ensure the stable bearing of the cutting material, which solves the problem of the difficulty in accurately positioning and stably bearing thicker cutting materials. It also realizes the flexible adjustment of the gap between the cutting material and the worktable, providing convenient conditions for the secondary laser cutting head to cut from the bottom, and improving the cutting efficiency and quality of thicker cutting materials.
[0018] 2. In this solution, a sliding component is provided, and the sliding block is moved by a telescopic motor. By using the connecting plug to engage with the meshing plate and the driven slider, the function of lifting the movable support plate before the side frame component moves is realized. Through the cooperation of the force-bearing base plate and the connecting torsion spring, the lifting plate can smoothly push the movable support plate upward, thereby reducing the impact of the weight of the workpiece on the side frame component's scooping operation. This allows the side frame component to scoop up thicker workpieces more easily and accurately, effectively solving the problem that thicker workpieces are difficult to scoop up smoothly by the side frame component due to their weight, and improving the overall laser cutting system's ability to handle thicker workpieces.
[0019] 3. In this solution, by incorporating a light-collecting component, the laser cutting process achieves both light collection and focusing, as well as collaborative cutting by the upper and lower dual cutting heads under special circumstances. The main electric telescopic rod pushes the outer light-collecting cover closer to the cutting area, effectively collecting and focusing the laser cutting light, reducing energy loss, and improving cutting efficiency. The cooperation of the auxiliary electric telescopic rod, electric turntable, and auxiliary laser cutting head allows for simultaneous operation of the upper and lower cutting heads when cutting thicker or specially shaped objects. The main laser cutting head first cuts the upper surface, and then the auxiliary laser cutting head cuts the lower surface. At the same time, the strong auxiliary gas output power of the auxiliary laser cutting head can also correct the collapse and deformation of the cutting surface, ensuring the integrity of the cutting surface.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Example 1: Please refer to Figures 1 to 9 A semi-automatic laser cutting machine, comprising:
[0032] The bottom support plate 1 serves as the stable base of the entire semi-automatic laser cutting machine. It is made of high-strength, wear-resistant alloy material to ensure it can withstand various working loads without deformation during long-term use. A worktable body 2 is mounted on the upper surface of the bottom support plate 1. Two fixed support plates 5 are mounted on the upper surface of the worktable body 2, with a movable support plate 6 positioned between them. These two fixed support plates 5 and the movable support plate 6 provide a fixed and reliable support point for placing the workpiece. Sliding blocks 3 are also mounted on both sides of the upper surface of the bottom support plate 1. Force-bearing side plates 7 are mounted on the upper surface of the sliding blocks 3. A top sliding frame 8 is mounted on the upper surface of the two force-bearing side plates 7. A sliding main block 9 is mounted on the surface of the top sliding frame 8. The sliding main block 9 is connected to the top sliding frame 8 via a precision linear guide rail, allowing it to move precisely in a straight line along the top sliding frame 8 under the action of an internal drive device, thereby ensuring the stability of the main laser cutting... The cutting head 31 can accurately reach the designated cutting position. The bottom surface of the sliding main block 9 is equipped with the main laser cutting head 31. The main laser cutting head 31 is one of the core components of the entire cutting machine. It integrates a high-power laser generator, a focusing optical system and a precise control system. It can emit a high-energy-density laser beam to quickly and accurately cut various metal materials. The bottom surface of the two force-bearing side plates 7 is also equipped with a bottom meshing block 17. The upper surface of the bottom support plate 1 has sliding slots 4 on both sides to facilitate the connection between the sliding block 3 and the bottom meshing block 17. The sliding slots 4 can ensure that the bottom meshing block 17 can slide freely in it, and can also precisely limit its movement trajectory to prevent it from deviating or getting stuck. The bottom meshing block 17 has a meshing hole in the center. The bottom surface of the worktable body 2 is equipped with a bottom motor 19. The bottom meshing rod 18 is provided at the end of the output shaft of the bottom motor 19. The bottom meshing rod 18 meshes with the meshing hole in the center of the bottom meshing block 17.
[0033] In use, the bottom motor 19 is started by sending a control signal to the operator, which drives the bottom meshing rod 18 to rotate. Since the bottom meshing rod 18 meshes with the meshing hole at the center of the bottom meshing block 17, it drives the bottom meshing block 17 to move, so that the sliding block 3 slides in the sliding slot 4. The top sliding frame 8 is moved by the force-bearing side plate 7, and finally the sliding main block 9 and the main laser cutting head 31 on its bottom surface are flexibly adjusted in the horizontal position above the worktable body 2.
[0034] An auxiliary mechanism is also provided on the upper surface of the bottom support plate 1. The auxiliary mechanism includes a light-collecting component and a lifting component. The light-collecting component includes a main electric telescopic rod 33, which is located on one side surface of the sliding main block 9. An outer light-collecting cover 32 is provided at the end of the output shaft of the main electric telescopic rod 33. The outer light-collecting cover 32 is made of a high-reflectivity metal material, and its inner surface is specially polished to effectively reduce the scattering and loss of laser light during propagation. The outer light-collecting cover 32 is generally horn-shaped, with the large opening facing the laser cutting area and the small opening connected to the internal structure, which can collect the reflected and scattered laser light generated during the cutting process to the greatest extent. A top arc cover 34 is provided on the upper surface of the outer light-collecting cover 32. The top arc cover 34 can guide and focus the light. A circular hole is opened at the center of the top arc cover 34 to facilitate the normal operation of the main laser cutting head 31. A top arc cover 34 is provided at the center of the outer light-collecting cover 32. There is an inner light-collecting mask 35, which is also made of a high-reflectivity material. The inner light-collecting mask 35 has connecting rods 36 on both sides. The other end of the connecting rods 36 is connected to the inner side surface of the outer light-collecting mask 32. The sliding main block 9 also has a secondary electric telescopic rod 29 on one side surface. The output shaft of the secondary electric telescopic rod 29 has a bottom connecting block 30 at the end. The bottom connecting block 30 is made of high-strength alloy material and has good load-bearing capacity and stability. The bottom surface of the bottom connecting block 30 has an electric turntable 37. The bottom surface of the electric turntable 37 has a bottom auxiliary frame 38. The side surface of the bottom auxiliary frame 38 has a secondary laser cutting head 40. The upper surface of the bottom auxiliary frame 38 also has a protective cover plate 39. The upper surface of the protective cover plate 39 also has a round hole to facilitate the normal operation of the secondary laser cutting head 40.
[0035] Before the cutting operation begins, the main electric telescopic rod 33 is activated, and its output shaft pushes the outer light-collecting mask 32 towards the main laser cutting head 31, causing the main laser cutting head 31 to enter the circular hole at the center of the outer light-collecting mask 32 and the inner light-collecting mask 35, bringing it close to the cutting area. During the cutting operation, the outer light-collecting mask 32 can effectively collect and focus the light generated during laser cutting, and refract the light into the interior of the inner light-collecting mask 35 through the top arc mask 34. Through the focusing effect of the inner light-collecting mask 35, the light is refocused on the cutting position, reducing energy loss and improving cutting efficiency. For efficiency, when the object to be cut has a special shape and a thickness exceeding the optimal cutting standard (such as a solid square steel bar), the operator can use a signal to drive the lifting assembly to lift the object and activate the auxiliary electric telescopic rod 29. This causes its output shaft to lower the bottom connecting block 30 to its lowest position. Subsequently, the operator's signal drives the electric turntable 37 to rotate, causing the bottom auxiliary frame 38 to rotate the auxiliary laser cutting head 40 180 degrees, positioning it below the main laser cutting head 31. During cutting, the two... The primary laser cutting head 31 cuts simultaneously from both the top and bottom sides of the workpiece, thereby improving cutting efficiency when cutting thicker workpieces. Because the primary laser cutting head 31 is closer to the workpiece than the secondary laser cutting head 40, the primary laser cutting head 31 first cuts the workpiece from the top surface, and then the secondary laser cutting head 40 cuts it from the bottom surface, separating the workpiece from the point where it was not completely cut. In addition, during the cutting process of the primary laser cutting head 31, the cut surface of the workpiece may collapse downwards due to the high heat and the effect of the auxiliary gas. The secondary laser cutting head 40, having a stronger auxiliary gas output power than the primary laser cutting head 31, pushes the collapsed position back into place using the auxiliary gas generated during its secondary cutting process after the primary laser cutting head 31 has made its first cut, thus ensuring the integrity of the cut surface. The protective cover 39 protects the secondary laser cutting head 40 from the downward falling debris generated by the primary laser cutting head 31 during its movement.
[0036] The lifting assembly mainly consists of a side frame component and a sliding component working together to improve the applicability and cutting accuracy of the equipment. The lifting assembly includes a side frame component and a sliding component. The side frame component includes an internal motor 12. Two hidden cavities 14 are formed inside the upper surface of the bottom support plate 1. These hidden cavities 14 provide a safe and stable installation space for key components such as the internal motor 12, while avoiding interference and collisions from external factors. The internal motor 12 is located on the inner side surface of one of the hidden cavities 14. A dual-axis screw 13 is installed at the output end of the hidden cavity 14. The surface of the 13 has two meshing plates 10. A connecting base 47 is provided on one side surface of the meshing plate 10. A long storage box 15 is provided on the upper surface of the connecting base 47. A connecting shaft 43 is provided at the connection between the long storage box 15 and the connecting base 47. An adjusting motor is provided at the other end of the connecting shaft 43. A driven slider 44 is provided at the end of the connecting base 47 away from the meshing plate 10. Two limiting plates 16 are provided inside each hidden cavity 14 to limit the sliding distance between the driven slider 44 and the meshing plate 10. The adjusting motor is located at the driven slider. On the upper surface of storage box 15, a support strip 41 is provided. The support strip 41 is made of high-strength, wear-resistant material, providing a stable support platform for the clamping side plate 42. The upper surface of the support strip 41 is equipped with the clamping side plate 42. One side surface of the support strip 41 is equipped with an anti-slip buffer plate 45, made of elastic and anti-slip material. This increases friction with the object being cut and provides cushioning, preventing scratches or damage to the surface of the object during lifting. The interior of the box 15 is provided with a sliding movable shovel block 46. The upper surface of the interior of the long storage box 15 is provided with a protrusion to prevent the movable shovel block 46 from completely disengaging. The upper surface of the interior of the long storage box 15 is also provided with an internal rotating plate 50. A pivot is provided at the connection between the internal rotating plate 50 and the upper surface of the interior of the long storage box 15. The interior of the long storage box 15 is also provided with an inclined block 51. A sliding groove 52 is provided on the upper surface of the inclined block 51. A sliding support movable strip 48 is provided inside the sliding groove 52. A weight block 49 is also provided on the upper surface of the support movable strip 48.
[0037] When in use, if the workpiece is thick, after the workpiece is placed on the workbench, the internal motor 12 can be started by the operator's signal, driving the dual-axis screw 13 to rotate. Since the dual-axis screw 13 engages with the two meshing plates 10, the two meshing plates 10 move inward, driving the storage box 15 to move via the connecting base frame 47. During the inward movement of the two storage boxes 15, the two movable scraper blocks 46 will scrape up the workpiece from both sides, causing it to detach from the upper surface of the fixed support plate 5. Subsequently, the adjusting motor can be started by the operator, driving the connecting shaft 43 to rotate, causing the entire storage box 15 to rotate 90 degrees. During this process, the supporting movable bar 48 slides along the sliding groove 52 opened on the upper surface of the inclined block 51 under the action of the weight block 49, thereby... The supporting movable bar 48 loses its restrictive effect on the internal rotating plate 50. Subsequently, the internal rotating plate 50 rotates via the pivot, causing it to lose its locking effect on the movable shovel block 46. Then, the movable shovel block 46 slides down with the rotation of the storage box 15 and enters the storage box 15 for storage. At this time, the two ends of the cutting object are supported by one side surface of the two storage boxes 15. The two ends of the cutting object are restricted by the clamping side plates 42. As the two meshing plates 10 move, the two clamping side plates 42 will clamp the two sides of the cutting object. The anti-slip buffer plate 45 can prevent the cutting object from sliding during the carrying process. At this time, there is a certain gap between the cutting object and the worktable. At this time, the auxiliary laser cutting head 40 can be inserted from the bottom side of the cutting object to its underside, and work with the main laser cutting head 31 to complete the aligned cutting effect.
[0038] As the core component of the laser cutting equipment for achieving precise workpiece lifting and flexible adjustment, the lifting assembly's sliding parts are particularly crucial. There are two sliding parts, each housed within a hidden cavity 14. The sliding parts within the two hidden cavities 14 have identical structures. Each sliding part includes two telescopic motors 21, each located within a hidden cavity 14. The output shafts of the two motors 21 each have a sliding block 11 at their ends. The side surface of the sliding block 11 has two parallel limiting grooves 20, ensuring the sliding support rod 27 can slide freely within them while reasonably limiting its sliding range. The sliding support rod 27 is housed within the limiting grooves 20. A side main block 25 is located on one side surface of the sliding support rod 27, and a connecting plug 26 is located on the side surface of the side main block 25 facing away from the sliding support rod 27. The connecting plug 26 is made of high-strength alloy steel. The dimensions of the side main block 25 are precisely designed based on the insertion holes opened on one side surface of the meshing plate 10 and the driven slider 44 to ensure that it can be tightly inserted into the insertion holes and realize a stable connection between the side main block 25 and the meshing plate 10 and the driven slider 44. The meshing plate 10 and the driven slider 44 are both provided with insertion holes that cooperate with the connecting insertion block 26 on one side surface. The side main blocks 25 are both provided with a force-bearing base plate 24. The force-bearing base plate 24 is made of thick steel plate and has sufficient strength and rigidity to withstand large external forces without deformation. A connecting torsion spring 23 is provided at the connection between the force-bearing base plate 24 and the side main block 25. The connecting torsion spring 23 is made of high-quality spring steel and has good elasticity and fatigue life. A lifting plate 22 is provided between the two force-bearing base plates 24. The two ends of the lifting plate 22 are also provided with connecting torsion springs 23 at the connection between them and the two force-bearing base plates 24. A bottom limiting block 28 is provided on the bottom surface of the lifting plate 22.
[0039] The sliding component is used to reduce the weight of the workpiece, making it easier for the side frame components to scoop it up. Under normal conditions, the two connecting blocks 26 do not engage with the insertion holes on the side surfaces of the meshing plate 10 and the driven slider 44. In use, before the two meshing plates 10 of the side frame components are ready to move, the two telescopic motors 21 extend, driving the sliding block 11 to move and approach the meshing plate 10, ultimately causing the two connecting blocks 26 to be inserted into the insertion holes. Subsequently, when the meshing plate 10 and the driven slider 44 move inward, the two side main blocks 25 also move synchronously. Finally, the lifting plate 22 is pushed upward by the two force-bearing base plates 24, so that the two force-bearing side plates 7 are simultaneously subjected to an upward pushing force, ultimately causing the movable bearing plate 6 to move upward, raising the position of the workpiece, making it easier for it to be scooped up by the side frame components on both sides for subsequent cutting work.
[0040] The working principle of this invention is:
[0041] In this solution, the bottom support plate 1 serves as a stable base, on which multiple key components work together to achieve efficient and precise cutting. In terms of placing the cutting object, a worktable 2 is set on the upper surface of the bottom support plate 1. The worktable 2 has two fixed support plates 5 and one movable support plate 6, which together provide a fixed support point for the cutting object. The cutting position adjustment is mainly driven by the bottom motor 19. When the operator sends a control signal, the bottom motor 19 starts, and its output shaft drives the bottom meshing rod 18 to rotate. Since the bottom meshing rod 18 meshes with the meshing hole at the center of the bottom meshing block 17, it drives the bottom meshing block 17 to move. The bottom meshing block 17 slides in the sliding slot 4 and drives the top sliding frame 8 to move through the force-bearing side plate 7. The sliding main block 9 on the top sliding frame 8 is connected by a precision linear guide rail and moves precisely in a straight line along the top sliding frame 8 under the action of the driving device, so that the main laser cutting head 31 on the bottom surface of the sliding main block 9 accurately reaches the designated cutting position.
[0042] During the cutting process, the light-collecting component plays an important role. When the main electric telescopic rod 33 is activated, its output shaft pushes the outer light-collecting mask 32 to move towards the main laser cutting head 31, allowing the main laser cutting head 31 to enter the circular hole in the center of the outer light-collecting mask 32 and the inner light-collecting mask 35. During cutting, the outer light-collecting mask 32 collects reflected and scattered laser light, which is refracted through the top arc mask 34 to the inner light-collecting mask 35, and then focused back onto the cutting position, reducing energy loss and improving cutting efficiency.
[0043] When cutting thicker materials, the lifting assembly starts to work. The sliding part of the lifting assembly moves first, and the two telescopic motors 21 extend, driving the sliding block 11 to approach the meshing plate 10, so that the connecting plug 26 is inserted into the insertion hole on the side surface of the meshing plate 10 and the driven slider 44. When the meshing plate 10 and the driven slider 44 move inward, the lifting plate 22 is pushed upward by the side main block 25 and the force-bearing base plate 24, so that the movable support plate 6 rises, making it easier for the cutting material to be scooped up by the side frame component.
[0044] The internal motor 12 of the side frame component starts, driving the dual-axis screw 13 to rotate, causing the two meshing plates 10 to move inward. This moves the storage box 15 through the connecting base frame 47. The movable shovel 46 scoops up the object to be cut and separates it from the fixed support plate 5. The adjusting motor drives the connecting shaft 43 to rotate, and the storage box 15 rotates ninety degrees. The movable shovel 46 slides down for storage. The two ends of the object to be cut are supported by the storage box 15 and restricted by the clamping side plate 42. At this time, the auxiliary laser cutting head 40 can be inserted from the bottom of the object to be cut, and work with the main laser cutting head 31 to complete the cutting of both the upper and lower sides simultaneously, improving the efficiency of cutting thicker objects. In addition, the auxiliary gas of the auxiliary laser cutting head 40 can also correct the deformation of the cut surface of the object to be cut, ensuring the cutting quality.
