Description

Technical Field

[0001] This invention belongs to the field of laser cutting machine technology, specifically a fully automatic feeding laser cutting machine. Background Technology

[0002] Laser cutting uses an invisible laser beam instead of a traditional mechanical blade, offering advantages such as high precision, fast cutting speed, no limitation on cutting patterns, automatic layout for material saving, smooth cuts, and low processing costs. It is gradually improving upon or replacing traditional metal cutting equipment. The mechanical parts of the laser head do not contact the workpiece, preventing scratches on the workpiece surface during operation. Laser cutting is fast, producing smooth and flat cuts that generally require no further processing. It also features a small heat-affected zone, minimal sheet deformation, narrow kerf, no mechanical stress, no shearing burrs, high processing precision, good repeatability, and no damage to the material surface. CNC programming allows for the processing of any planar shape, enabling the cutting of large sheets without the need for molds, saving time and money.

[0003] However, in practical industrial applications, existing laser cutting equipment generally suffers from insufficient automatic loading capabilities. Many machines still rely on manual loading and unloading of workpieces. Operators must manually move the workpieces to the cutting table and remove the finished product after cutting. This process is cumbersome, time-consuming, significantly increases the labor intensity of workers, and is prone to workpiece positioning deviations due to fatigue or negligence, affecting cutting accuracy and product quality. At the same time, manual loading and unloading is inefficient, becoming a key bottleneck in the production process and limiting the overall processing speed of the equipment. To maintain normal operation, each laser cutting machine typically requires multiple workers dedicated to the loading and unloading process, significantly increasing labor costs for enterprises. Summary of the Invention

[0004] The purpose of this application is to provide a fully automatic feeding laser cutting machine that solves the problems of low efficiency and high labor intensity of manual operation.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a fully automatic feeding laser cutting machine, including a main frame, a feeding conveyor belt for conveying workpieces is provided on the main frame, a cutting frame is fixedly provided on one side of the main frame, a cutting table is provided on the cutting frame, and a cutting mechanism for laser cutting workpieces is fixedly provided at the upper end of the cutting frame. Two sets of feeding mechanisms are fixedly installed at the upper end of the main frame. The feeding mechanism is fixedly equipped with a suction mechanism for adsorbing and clamping the workpiece. The cooperation of the two sets of feeding mechanisms and suction mechanisms is used to send the workpiece on the feeding conveyor belt into the cutting table for laser cutting and to take out the workpiece after laser cutting in the cutting table and send it onto the feeding conveyor belt. A feeding drive is fixedly installed on the side of the main frame away from the cutting frame. The feeding drive is used to drive the suction mechanism to slide back and forth on the feeding mechanism. The feeding drive includes a motor support fixedly installed on the side wall of the main frame. A feeding motor is fixedly installed on the motor support. A bearing seat is fixedly installed at the upper end of the motor support. A connecting shaft 1 is fixedly installed on the inner ring of the bearing seat. The connecting shaft 1 is driven to the output shaft of the feeding motor through a belt drive. The connecting shaft 1 is driven to one of the feeding mechanisms. The output shaft of the feeding motor is also connected to a connecting shaft 2. The connecting shaft 2 is driven to another feeding mechanism. The connecting shaft 1 and the connecting shaft 2 are linked by a linkage mechanism. The linkage mechanism realizes the independent rotation of the connecting shaft 1 and the connecting shaft 2, as well as the synchronous rotation of the connecting shaft 1 and the connecting shaft 2. This allows a single feeding mechanism and a suction mechanism to load and unload workpieces, or two sets of feeding mechanisms and suction mechanisms to load and unload workpieces simultaneously.

[0006] Preferably, the cutting mechanism includes a cutting bracket fixedly mounted on the upper end of the cutting machine frame, the upper part of the cutting bracket being slidably mounted on a cutting slide, the lower end of the cutting slide being slidably mounted on a translation slide, the translation slide being perpendicular to the moving direction of the cutting slide, the lower end of the translation slide being fixedly mounted on a lifting cylinder, and the output end of the lifting cylinder being fixedly mounted on a laser cutter.

[0007] Preferably, a threaded screw is rotatably mounted on the upper part of the cutting bracket, a cutting motor for driving the threaded screw to rotate is fixedly mounted on the outer wall of the cutting bracket, the cutting slide is threaded through the threaded screw, and multiple cutting guide rods are fixedly arranged on the upper part of the cutting bracket, with the cutting slide slidably connected to the cutting guide rods.

[0008] Preferably, the feeding mechanism includes a feeding base fixedly installed on the upper end of the main frame, a feeding guide rail fixedly installed on the upper end of the feeding base, a feeding slider slidably installed on the feeding guide rail, a feeding slide block fixedly installed on the upper end of the feeding slider, two sets of feeding pulleys rotatably installed on the side end of the feeding base, one set of feeding pulleys being connected to the feeding drive transmission, a feeding belt being connected between the two sets of feeding pulleys, and a belt clamp fixedly installed at the lower end of the feeding slide block and fixedly connected to the feeding belt.

[0009] Preferably, the linkage mechanism includes a linkage base fixedly mounted on the upper end of the main frame. A bearing support connected to connecting shaft one and connecting shaft two is fixedly mounted on the upper end of the linkage base. Two sets of upright plates one and two sets of upright plates two are fixedly mounted on the linkage base. A shaft one is rotatably mounted between the two sets of upright plates one, and a shaft two is rotatably mounted between the two sets of upright plates two. A gear two is fixedly mounted on the shaft one, and a gear one that meshes with gear two is fixedly mounted on the connecting shaft one. The shaft one and shaft two are connected by a linkage component, and the shaft two and connecting shaft two are connected by a belt drive two.

[0010] Preferably, the linkage includes a drive rod 1 in the shape of a polygonal prism, with a drive rod 2 rotatably mounted at one end of the drive rod 1 near the shaft 2 via a connecting bearing. One end of the shaft 1 is provided with a drive hole that mates with the drive rod 1, and one end of the shaft 2 is provided with a connecting hole that mates with the drive rod 1. A shaft through hole is provided at the bottom of the connecting hole, and the drive rod 2 is connected through the shaft through hole.

[0011] Preferably, a vertical plate three is fixedly installed at the upper end of the linkage base away from the vertical plate one. An electric push rod is horizontally fixedly installed on the vertical plate three. The output end of the electric push rod is fixedly connected to the drive rod two. The electric push rod drives the drive rod two to move horizontally, and the relative position of the drive rod one is adjusted to realize the transmission control of the shaft one and the shaft two. When only one set of suction mechanism is needed to feed the workpiece, the electric push rod extends and drives the drive rod one to move towards the shaft one, so that the drive rod one is inserted into the drive hole and separated from the connection hole. At this time, the rotational connection between the drive rod one and the drive rod two is made through the connecting bearing, so that the rotation of the shaft one is controlled. The rotation of the first shaft will not synchronously drive the second shaft to rotate. When the two sets of suction mechanisms need to load and unload workpieces synchronously, the electric push rod retracts, driving the first drive rod to move towards the second shaft. This allows the two ends of the first drive rod to be inserted into the drive hole and the connecting hole, respectively. Thus, the first shaft and the second shaft rotate synchronously under the drive of the first drive rod, thereby synchronously driving the two sets of suction mechanisms. Furthermore, through the meshing transmission of the first gear and the second gear, the rotation directions of the first connecting shaft and the second connecting shaft are reversed, resulting in the opposite movement directions of the two sets of suction mechanisms. This achieves synchronous loading and unloading, thereby reducing loading and unloading time and improving cutting efficiency.

[0012] Preferably, the suction mechanism includes a suction lifting cylinder fixedly mounted vertically upward on the loading slide, a lifting plate fixedly mounted at the output end of the suction lifting cylinder, a vertically downward rotary motor fixedly mounted on the lifting plate, a suction seat plate fixedly mounted on the output shaft of the rotary motor, a plurality of suction support plates fixedly provided at the lower end of the suction seat plate, and suction heads for adsorbing or clamping workpieces mounted on the suction support plates.

[0013] Preferably, the suction support plate is provided with an adjustment waist hole, and two sets of adjustment screws are slidably arranged at the adjustment waist hole. Two sets of locking nuts are threadedly connected to the adjustment screws. The two sets of locking nuts are located at the upper and lower ends of the suction support plate, respectively. The suction head is fixedly installed at the lower end of the adjustment screw. The upper parts of multiple sets of adjustment screws located on the same side are connected by a linkage plate. The upper end of the suction base plate is fixedly provided with an adjustment drive for driving the suction heads on both sides to adjust the relative distance, thereby adapting to the suction or clamping of different workpieces.

[0014] Preferably, the adjustment drive includes an adjustment guide rail fixedly mounted on the upper end of the suction seat plate, an adjustment slider slidably connected to the adjustment guide rail, a slider pin fixedly mounted at the upper center of the adjustment slider, two sets of drive linkages rotatably connected to the slider pin, and a connecting pin fixedly mounted on the linkage plate and rotatably connected to the drive linkages; an adjustment vertical plate is fixedly mounted at one end of the adjustment guide rail, an adjustment telescopic cylinder is fixedly mounted on the adjustment vertical plate, and the output end of the adjustment telescopic cylinder is fixedly connected to the adjustment slider.

[0015] The beneficial effects of this invention are as follows: The integrated automatic loading and unloading system effectively solves the problems of low efficiency, high labor intensity, and high labor costs associated with manual loading and unloading in traditional laser cutting machines. The coordination of the feeding conveyor belt, two sets of loading mechanisms, and the suction mechanism achieves full automation of the workpiece process from conveying and cutting to removal, significantly reducing reliance on manual labor. In particular, the design of the linkage mechanism allows the two sets of loading and suction mechanisms to operate independently or synchronously according to actual needs, improving the flexibility of equipment operation and overall processing efficiency, thereby optimizing the production process and reducing operating costs.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-9As shown, this embodiment of the invention provides a fully automatic laser cutting machine with feeding mechanism, including a main frame 1, a feeding conveyor belt 2, a cutting frame 3, a cutting table 4, and a cutting mechanism 5, forming a basic cutting platform. Two sets of feeding mechanisms 8 and suction mechanisms 9 are provided to automatically feed workpieces into the cutting table 4 for cutting and to remove the cut workpieces from the cutting table 4. Furthermore, the feeding drive 6 drives the suction mechanism 9 to reciprocate, and the linkage mechanism 7 enables the independent or synchronous rotation of connecting shaft 1 65 and connecting shaft 2 66, thereby allowing for flexible coordination of single or both sets of feeding mechanisms 8 and suction mechanisms 9, effectively solving the problems of low efficiency and high cost associated with traditional manual feeding and unloading.

[0021] The main frame 1, as the overall support frame of the equipment, can be constructed in various forms such as welded steel structure, cast structure or modular assembly structure to ensure the rigidity and stability of the entire equipment.

[0022] The feeding conveyor belt 2 is mounted on the main frame 1 and is used for continuous conveying of workpieces. The feeding conveyor belt 2 can be composed of various types such as rubber belt, chain conveyor belt, roller conveyor belt or mesh belt. It is driven by a drive motor to circulate, so as to realize the smooth feeding and discharging of workpieces.

[0023] The cutting frame 3 is fixedly mounted on one side of the main frame 1 to support the cutting table 4 and the cutting mechanism 5. The cutting table 4 is mounted on the cutting frame 3 and carries the workpiece to be cut. The cutting table 4 can be designed as a flat plate, grid, or honeycomb structure to adapt to different materials and cutting requirements. The cutting mechanism 5 is fixedly mounted on the upper end of the cutting frame 3 for laser cutting of the workpiece. The cutting mechanism 5 may include basic components such as a laser generator, an optical transmission system, and a cutting head.

[0024] Two sets of feeding mechanisms 8 are fixedly mounted on the upper end of the main frame 1 to guide the movement of the suction mechanism 9. The feeding mechanism 8 can be composed of various forms such as guide rail and slider system, linear module or robotic arm, to provide a precise motion trajectory for the suction mechanism 9.

[0025] The suction mechanism 9 is fixedly installed on the feeding mechanism 8 and is used to adsorb and clamp the workpiece. The suction mechanism 9 can include various forms such as vacuum suction cups, mechanical grippers or electromagnetic suction cups, and the appropriate adsorption or clamping method can be selected according to the material, shape and size of the workpiece.

[0026] The two sets of feeding mechanisms 8 and suction mechanisms 9 work together to feed workpieces from the feeding conveyor belt 2 into the cutting table 4 for laser cutting, and to remove laser-cut workpieces from the cutting table 4 and feed them back onto the feeding conveyor belt 2. This coordination method can be used in a sequential manner, i.e., feeding is completed before cutting, or cutting is completed before unloading. For example, one set of suction mechanisms 9 picks up the workpiece from the feeding conveyor belt 2 and places it on the cutting table 4, while the other set of suction mechanisms 9 picks up the workpiece from the cutting table 4 and places it back onto the feeding conveyor belt 2 after cutting.

[0027] The feeding drive 6 is fixedly mounted on the side of the main frame 1 away from the cutting frame 3, and is used to drive the suction mechanism 9 to slide back and forth on the feeding mechanism 8. The feeding drive 6 can adopt various mechanical transmission methods such as motor-driven screw drive, gear and rack drive, or synchronous belt drive.

[0028] The feeding drive 6 includes a motor support 61 fixedly mounted on the side wall of the main frame 1, and a feeding motor 62 is fixedly mounted on the motor support 61. The motor support 61 can be formed by bending and welding or casting metal sheet, and is used to securely mount the feeding motor 62. The feeding motor 62 can be an AC servo motor, a DC motor, or a stepper motor, etc., selected according to the required driving accuracy and speed.

[0029] A bearing housing 63 is fixedly mounted on the upper end of the motor support 61, and a connecting shaft 65 is fixedly mounted on the inner ring of the bearing in the bearing housing 63. The bearing housing 63 can be a split or integral structure, and a rolling bearing or a sliding bearing is installed inside to support the rotation of the connecting shaft 65. The connecting shaft 65 can be a solid or hollow shaft, made of high-strength steel, and is used to transmit torque.

[0030] The connecting shaft 65 is connected to the output shaft of the feeding motor 62 via a belt drive 64. The belt drive 64 can be a synchronous belt drive, a V-belt drive, or a flat belt drive, etc., to transmit the rotational power of the feeding motor 62 to the connecting shaft 65.

[0031] The connecting shaft 65 is connected to one of the feeding mechanisms 8 via a transmission connection. This transmission connection can be achieved by means of gear transmission, chain transmission, or direct coupling connection, which converts the rotational motion of the connecting shaft 65 into the linear reciprocating motion of the feeding mechanism 8.

[0032] The output shaft of the feeding motor 62 is also connected to a second connecting shaft 66, which is connected to another feeding mechanism 8 via a transmission connection. The connection and transmission methods of the second connecting shaft 66 can be similar to those of the first connecting shaft 65. The first connecting shaft 65 and the second connecting shaft 66 are linked by a linkage mechanism 7. The linkage mechanism 7 can take various forms, such as a mechanical clutch, an electromagnetic clutch, or a planetary gear set, to achieve independent or synchronous transmission of the two connecting shafts.

[0033] The linkage mechanism 7 enables independent rotation of connecting shaft 1 65 and connecting shaft 2 66, as well as synchronous rotation of connecting shaft 1 65 and connecting shaft 2 66. This allows a single feeding mechanism 8 and suction mechanism 9 to load and unload workpieces, or for two sets of feeding mechanisms 8 and suction mechanisms 9 to load and unload workpieces simultaneously. For example, when the linkage mechanism 7 is in independent rotation mode, the feeding motor 62 drives only one connecting shaft, enabling one set of feeding mechanisms 8 and suction mechanisms 9 to operate. When the linkage mechanism 7 is in synchronous rotation mode, the feeding motor 62 drives both connecting shafts simultaneously, enabling two sets of feeding mechanisms 8 and suction mechanisms 9 to work collaboratively, for example, one set loads while the other unloads.

[0034] The fully automatic laser cutting machine of this embodiment effectively solves the problems of low efficiency, high labor intensity, and high labor costs associated with manual loading and unloading in traditional laser cutting machines through its integrated automatic loading and unloading system. The cooperation of its feeding conveyor belt 2, two sets of loading mechanisms 8, and suction mechanism 9 achieves full automation of the workpiece process from conveying, cutting, to removal, significantly reducing reliance on manual labor. In particular, the design of the linkage mechanism 7 allows the two sets of loading mechanisms 8 and suction mechanism 9 to operate independently or synchronously according to actual needs, improving the flexibility of equipment operation and overall processing efficiency, thereby optimizing the production process and reducing operating costs.

[0035] In some of the embodiments described above in this application, a cutting mechanism is proposed for laser cutting of workpieces. However, in its implementation, the movement of the cutting mechanism may not be precise or flexible enough, resulting in unstable cutting quality or low efficiency.

[0036] In this regard, this application further proposes a fully automatic feeding laser cutting machine; please refer to [link / reference]. Figures 1-3 As shown, the cutting mechanism 5 includes a cutting bracket 51 fixedly mounted on the upper end of the cutting frame 3. The upper part of the cutting bracket 51 is slidably mounted on the cutting slide 55. The lower end of the cutting slide 55 is slidably mounted on a translation slide 56. The translation slide 56 is perpendicular to the moving direction of the cutting slide 55. The lower end of the translation slide 56 is fixedly mounted on a lifting cylinder 57. The output end of the lifting cylinder 57 is fixedly mounted on a laser cutter 58.

[0037] Through the above technical solution, the cutting mechanism 5 of this application achieves precise positioning of the laser cutter 58 through a multi-axis movement system, thereby effectively solving the problem of insufficient precision or flexibility in the movement of existing cutting mechanisms. The cutting bracket 51 is fixed on the cutting frame 3, providing a stable support foundation and ensuring that the entire mechanism does not shift during the cutting process. The cutting slide 55 slides on the upper part of the cutting bracket 51, realizing precise movement of the laser cutter 58 in one horizontal direction. The translation slide 56 slides at the lower end of the cutting slide 55, and its movement direction is perpendicular to the movement direction of the cutting slide 55, thereby realizing independent movement of the laser cutter 58 in another horizontal direction, together constituting precise control in a two-dimensional plane. In addition, the lifting cylinder 57 is fixed at the lower end of the translation slide 56 for vertical height adjustment, which can adapt to the cutting requirements of different workpiece thicknesses. The laser cutter 58 is directly installed at the output end of the lifting cylinder 57, ensuring precise focusing of the laser beam and execution of the cutting operation. This structure, through a combination of sliding setting and vertical movement, enables the laser cutter 58 to be precisely positioned in three-dimensional space, significantly improving cutting accuracy and processing efficiency, while also enhancing adaptability to different workpieces and cutting tasks.

[0038] In some of the embodiments described above in this application, a cutting mechanism is proposed to realize the movement of the laser cutter. However, in its implementation, the movement of the cutting slide may lack precise drive and stable guidance, resulting in inaccurate position control during the cutting process, which affects the cutting quality and efficiency.

[0039] For this, please refer to Figures 1-3 As shown, a threaded screw 53 is rotatably mounted on the upper part of the cutting bracket 51, and a cutting motor 52 for driving the threaded screw 53 to rotate is fixedly mounted on the outer wall of the cutting bracket 51. The cutting slide 55 is threaded through and mounted on the threaded screw 53, and a plurality of cutting guide rods 54 are fixedly arranged on the upper part of the cutting bracket 51. The cutting slide 55 is slidably connected to the cutting guide rods 54.

[0040] Through the above technical solution, the cutting motor 52 drives the lead screw 53 to rotate, precisely converting the rotational motion into the linear movement of the cutting slide 55, thereby achieving precise control of the position of the cutting slide 55. Simultaneously, multiple cutting guide rods 54 provide stable guidance and support for the cutting slide 55, effectively suppressing swaying and offset during movement. This design combining drive and guidance significantly improves the accuracy and stability of the cutting slide 55's movement, avoiding inaccurate position control problems caused by inaccurate drive and unstable guidance. Therefore, the laser cutter 58 can perform high-precision cutting along a preset path, effectively improving cutting quality, reducing scrap rate, and further enhancing the processing efficiency of the entire fully automatic feeding laser cutting machine.

[0041] In some of the embodiments described above in this application, a feeding mechanism is proposed to realize the automatic loading and unloading of workpieces. However, in the process of its implementation, the movement of the feeding mechanism may not be smooth or precise enough, resulting in the loading and unloading process being time-consuming and unreliable, which affects the overall cutting and processing efficiency.

[0042] In this regard, this application further proposes a fully automatic feeding laser cutting machine; please refer to [link / reference]. Figures 1-2 As shown, the feeding mechanism 8 includes a feeding base 81 fixedly installed on the upper end of the main frame 1. A feeding guide rail 82 is fixedly installed on the upper end of the feeding base 81. A feeding slider 85 is slidably installed on the feeding guide rail 82. A feeding slide block 86 is fixedly installed on the upper end of the feeding slider 85. Two sets of feeding pulleys 83 are rotatably installed on the side end of the feeding base 81. One set of feeding pulleys 83 is connected to the feeding drive 6. A feeding belt 84 is connected between the two sets of feeding pulleys 83. A belt clamp 87 is fixedly installed on the lower end of the feeding slide block 86 and is fixedly connected to the feeding belt 84.

[0043] Through the above technical solution, this application provides a structured feeding mechanism 8, which provides stable support through a feeding base 81, and achieves precise linear guidance and low-friction movement through a feeding guide rail 82 and a feeding slider 85. A feeding slide 86 carries the suction mechanism 9, and a belt drive system consisting of a feeding pulley 83, a feeding belt 84, and a belt clamp 87 smoothly and accurately transmits the power of the feeding drive 6 to the feeding slide 86. This design ensures the smooth movement and positioning accuracy of the suction mechanism 9 during workpiece loading and unloading, effectively solving the problems of unstable movement, time-consuming processes, and unreliable operation in traditional feeding processes. Overall, the introduction of this feeding mechanism 8 significantly improves the speed and reliability of workpiece loading and unloading, thereby increasing the overall processing efficiency of the fully automatic feeding laser cutting machine and reducing reliance on manual operation.

[0044] In some of the solutions mentioned above in this application, a linkage mechanism is proposed to realize the independent rotation and synchronous rotation of connecting shaft one and connecting shaft two, thereby controlling the working mode of the feeding mechanism. However, in its implementation, a specific structure is needed to reliably realize this switching in order to avoid complex operation or low efficiency.

[0045] For this, please refer to Figure 1 , Figures 4-7As shown, this application proposes a linkage mechanism 7, which includes a linkage base 71 fixedly mounted on the upper end of the main frame 1. A bearing support 714 connected to a connecting shaft 65 and a connecting shaft 66 is fixedly mounted on the upper end of the linkage base 71. Two sets of upright plates 711 and two sets of upright plates 712 are fixedly mounted on the linkage base 71. A shaft 74 is rotatably mounted between the two sets of upright plates 711, and a shaft 76 is rotatably mounted between the two sets of upright plates 712. A gear 73 is fixedly mounted on the shaft 74, and a gear 72 meshing with the gear 73 is fixedly mounted on the connecting shaft 65. The shaft 74 and the shaft 76 are connected by a linkage member 75, and the shaft 76 and the connecting shaft 66 are connected by a belt drive 77.

[0046] Through the above technical solutions, the linkage base 71, bearing support 714, vertical plate one 711, and vertical plate two 712 provide solid support and precise positioning for the entire linkage mechanism 7, ensuring stable operation of the transmission components under high-speed or heavy-load conditions. The meshing transmission between gear one 72 on connecting shaft one 65 and gear two 73 on shaft one 74 effectively transmits power from the feeding motor 62 to shaft one 74, ensuring transmission efficiency. The linkage component 75, as the core component, cleverly connects shaft one 74 and shaft two 76, allowing flexible switching between independent and synchronous rotation, thus avoiding the complexity of traditional mechanical switching mechanisms and improving operational convenience and reliability. Shaft two 76 is connected to connecting shaft two 66 via belt drive two 77, ensuring smooth power transmission to another set of feeding mechanisms 8. Overall, the linkage mechanism 7 provides a solution with a clear structure, reliable transmission, and easy control, enabling connecting shaft 1 65 and connecting shaft 2 66 to rotate independently or synchronously according to actual needs, thereby precisely controlling the working modes of the two sets of feeding mechanisms 8 and suction mechanisms 9. This not only simplifies the mode switching during feeding and discharging, avoiding the complexity and inefficiency caused by manual intervention, but also significantly improves the working efficiency and automation level of the fully automatic feeding laser cutting machine by achieving single feeding or synchronous feeding and discharging.

[0047] In some of the embodiments described above in this application, a linkage is proposed to connect shaft one and shaft two, thereby controlling the independent or synchronous rotation of connecting shaft one and connecting shaft two. However, in its implementation, the structure of the linkage may lack a precise movement control mechanism, resulting in complex operation and low reliability when switching between independent rotation and synchronous rotation modes, which affects the loading and unloading efficiency.

[0048] For this, please refer to Figure 1 , Figures 4-7As shown, this application proposes an improved linkage 75, the specific structure of which includes: the linkage 75 includes a driving rod 751 in the shape of a polygonal prism, the end of the driving rod 751 near the shaft 76 is rotatably mounted with a driving rod 753 via a connecting bearing 752, one end of the shaft 74 is provided with a driving hole 741 that cooperates with the driving rod 751, one end of the shaft 76 is provided with a connecting hole 761 that cooperates with the driving rod 751, the bottom of the connecting hole 761 is provided with a shaft through hole 762, and the driving rod 753 is connected through the shaft through hole 762.

[0049] Through the above technical solution, this application optimizes the specific structure of the linkage component 75 in the linkage mechanism 7, effectively solving the problems of insufficient precision, complex operation, and low reliability that may exist when switching the rotation modes of shaft 1 74 and shaft 2 76. Specifically, the drive rod 1 751 in the linkage component 75 is designed as a polygonal prism, and it is made to cooperate with the drive hole 741 on shaft 1 74 and the connecting hole 761 on shaft 2 76. This ensures that in the synchronous transmission mode, the drive rod 1 751 can form a tight and non-slip connection with the drive hole 741 and the connecting hole 761, thereby stably and reliably transmitting torque and significantly improving the stability of the transmission. At the same time, the drive rod 1 751 is rotatably mounted with the drive rod 2 753 through the connecting bearing 752. This design allows for relative rotation between the drive rod 1 751 and the drive rod 2 753. Thus, in the independent rotation mode, even if the drive rod 1 751 is inserted into the drive hole 741, shaft 2 76 can remain independent through the free rotation of the drive rod 2 753, avoiding unnecessary forced linkage and mechanical interference. Furthermore, the shaft through hole 762 at the bottom of the connecting hole 761 on shaft two 76, and the drive rod two 753 are connected through it, not only fixing the axial position of drive rod two 753, but also providing a structural basis for the flexible switching of drive rod one 751 between drive hole 741 and connecting hole 761. Overall, this structural design simplifies the mode switching operation process, enhances the reliability of linkage mechanism 7, ensures rapid and accurate switching between independent or synchronous rotation modes, and thus improves the adaptability and working efficiency of the fully automatic loading laser cutting machine in different workpiece loading and unloading scenarios.

[0050] In some of the embodiments described above in this application, a linkage mechanism is proposed to realize the independent or synchronous rotation of connecting shaft one and connecting shaft two. However, in its implementation, there is a lack of an automated control mechanism to switch the transmission mode, which requires manual adjustment of the drive rod position, making operation inconvenient and inefficient, affecting the flexibility of loading and unloading and the overall efficiency of cutting and processing.

[0051] For this, please refer to Figure 1 , Figures 4-7As shown, this application further proposes that a third vertical plate 713 is fixedly installed at the upper end of the linkage base 71 away from the first vertical plate 711. An electric push rod 78 is horizontally fixedly installed on the third vertical plate 713. The output end of the electric push rod 78 is fixedly connected to the second drive rod 753. The electric push rod 78 drives the second drive rod 753 to move horizontally, and the relative position of the first drive rod 751 is adjusted to realize the transmission control of the first shaft 74 and the second shaft 76. When only one set of suction mechanism 9 is needed to feed the workpiece, the electric push rod 78 extends and drives the first drive rod 751 to move toward the first shaft 74, so that the first drive rod 751 is inserted into the drive hole 741 and separated from the connecting hole 761. At this time, the rotation between the first drive rod 751 and the second drive rod 753 is achieved through the connecting bearing 752. The connection ensures that the rotation of shaft 74 will not synchronously drive shaft 76. When the two sets of suction mechanisms 9 need to load and unload workpieces synchronously, the electric push rod 78 retracts, driving the drive rod 751 towards shaft 76, so that the two ends of the drive rod 751 are respectively inserted into the drive hole 741 and the connecting hole 761. Thus, the synchronous rotation of shaft 74 and shaft 76 is achieved under the drive of the drive rod 751, thereby synchronously driving the two sets of suction mechanisms 9. Furthermore, through the meshing transmission of gear 72 and gear 73, the rotation directions of connecting shaft 65 and connecting shaft 66 are opposite, thus achieving opposite movement directions of the two sets of suction mechanisms 9. This enables synchronous loading and unloading, thereby reducing loading and unloading time and improving cutting efficiency.

[0052] The electric actuator 78 drives the second drive rod 753 to move horizontally, adjusting the relative position of the first drive rod 751 to achieve transmission control of the first shaft 74 and the second shaft 76. This is the core mechanism of the entire mode switching. The linear motion of the electric actuator 78 drives the second drive rod 753, which in turn connects to the first drive rod 751 (through the connecting bearing 752), enabling the first drive rod 751 to move horizontally. This allows it to selectively engage or disengage with the holes of the first shaft 74 and the second shaft 76, thereby controlling the transmission path.

[0053] When only one set of suction mechanism 9 is needed to feed the workpiece, the electric push rod 78 extends and drives the drive rod 751 to move towards the shaft 74, so that the drive rod 751 is inserted into the drive hole 741 and separated from the connecting hole 761. At this time, the drive rod 751 and the drive rod 753 are rotatedly connected through the connecting bearing 752, so the rotation of the shaft 74 will not synchronously drive the rotation of the shaft 76. In this mode, the electric push rod 78 extends and pushes the drive rod 751 into the drive hole 741 of the shaft 74, forming a rigid connection with the shaft 74, but at the same time the drive rod 751 is separated from the connecting hole 761 of the shaft 76. Since the drive rod 751 and the drive rod 753 are connected by the connecting bearing 752, relative rotation is allowed. Therefore, the rotation of the shaft 74 will not be transmitted to the shaft 76, realizing the independent operation of a single set of suction mechanism 9. The shapes of the drive hole 741 and the connecting hole 761 can be designed to match the polygonal prism shape of the drive rod 751, such as square or hexagonal holes, to ensure reliable transmission during insertion. The connecting bearing 752 can be a ball bearing or a sliding bearing to reduce friction between the drive rod 751 and the drive rod 753, ensuring smooth relative rotation between them in single-unit operating mode.

[0054] When two sets of suction mechanisms 9 are required to simultaneously load and unload workpieces, the electric push rod 78 retracts, driving the drive rod 751 to move towards the shaft 76, so that both ends of the drive rod 751 are inserted into the drive hole 741 and the connecting hole 761 respectively. This allows the shafts 74 and 76 to rotate synchronously under the drive of the drive rod 751. In this mode, the electric push rod 78 retracts, pulling the drive rod 751 so that both ends simultaneously insert into the drive hole 741 of the shaft 74 and the connecting hole 761 of the shaft 76. At this time, the drive rod 751 acts as a rigid connector, locking the shafts 74 and 76 together, achieving their synchronous rotation.

[0055] The meshing transmission of gears 72 and 73 enables the opposite rotation directions of connecting shafts 65 and 66, thus achieving opposite movement directions for the two sets of material suction mechanisms 9. This allows for synchronous loading and unloading, reducing loading and unloading time and improving cutting efficiency. The meshing transmission of gears 72 and 73 is crucial for achieving the reverse movement of the two sets of material suction mechanisms 9. When shafts 74 and 76 rotate synchronously, the gear transmission causes connecting shafts 65 and 66 to rotate in opposite directions, allowing the two sets of material suction mechanisms 9 to perform loading and unloading operations simultaneously.

[0056] Through the above technical solution, this application achieves automated switching of the transmission mode of the linkage mechanism 7 by introducing an electric push rod 78 and its cooperating linkage structure, effectively solving the problems of inconvenience and low efficiency of traditional manual adjustment. Specifically, the electric push rod 78 can precisely control the horizontal movement of the drive rod 751 according to actual needs, enabling it to quickly and reliably switch between the single-set suction mechanism 9 working mode and the synchronous working mode of two sets of suction mechanisms 9. In the single-set working mode, the electric push rod 78 extends, and the drive rod 751 is only connected to the shaft 74. Through the rotational connection characteristics of the connecting bearing 752, it is ensured that the rotation of the shaft 74 is not transmitted to the shaft 76, thereby realizing the independent operation of a single suction mechanism 9. In the two-set synchronous working mode, the electric push rod 78 retracts, and the drive rod 751 is simultaneously inserted into the shafts 74 and 76, forming a rigid connection, so that the two shafts rotate synchronously. Furthermore, through the meshing transmission of gear 1 72 and gear 2 73, the rotation directions of connecting shaft 1 65 and connecting shaft 2 66 are ensured to be opposite, thereby enabling the two sets of material suction mechanisms 9 to perform loading and unloading operations simultaneously, greatly shortening the waiting time for loading and unloading, significantly improving the overall efficiency and automation level of cutting and processing, and reducing the need for manual intervention.

[0057] In some of the embodiments described above in this application, a suction mechanism is proposed for adsorbing and clamping workpieces. However, in the implementation process, the suction mechanism may not be able to be flexibly adjusted to adapt to different workpiece shapes and sizes, resulting in weak adsorption or low efficiency.

[0058] For this, please refer to Figure 2 , Figures 8-9 As shown, this application further proposes a fully automatic feeding laser cutting machine, whose suction mechanism 9 includes a suction lifting cylinder 91 that is fixedly mounted vertically upward on the feeding slide 86. A lifting plate 92 is fixedly mounted on the output end of the suction lifting cylinder 91. A vertically downward rotary motor 93 is fixedly mounted on the lifting plate 92. A suction seat plate 94 is fixedly mounted on the output shaft of the rotary motor 93. A plurality of suction support plates 95 are fixedly arranged at the lower end of the suction seat plate 94. A suction head 97 for adsorbing or clamping workpieces is installed on the suction support plate 95.

[0059] Through the above technical solution, the suction mechanism 9 can achieve vertical height adjustment via the suction lifting cylinder 91 to adapt to workpieces of different thicknesses or stacking heights, ensuring that the suction head 97 can accurately contact the workpiece surface. Simultaneously, the rotary motor 93 drives the suction base plate 94 and its lower suction support plate 95 and suction head 97 to rotate, allowing the suctioned workpiece to be adjusted to the required angle, thereby achieving precise alignment and orientation of the workpiece and greatly improving the flexibility and accuracy of loading and unloading. Furthermore, the multiple suction support plates 95 at the lower end of the suction base plate 94 and the suction heads 97 mounted on them provide multiple suction points, increasing the contact area with the workpiece. This ensures stable and secure suction or clamping of workpieces of different sizes and shapes, effectively avoiding the risk of workpiece detachment during handling. This structural design allows the suction mechanism 9 to flexibly adapt to various workpieces, solving the shortcomings of traditional suction mechanisms in terms of adaptability, significantly improving the efficiency and reliability of the fully automatic loading laser cutting machine when handling diverse workpieces, and reducing the need for manual intervention.

[0060] In some of the embodiments described above in this application, a suction mechanism is proposed for adsorbing or clamping workpieces. However, in its implementation, since the workpiece size may be different, the fixed position of the suction head cannot be flexibly adapted, which requires manual intervention to adjust or replace parts, reducing processing efficiency and automation.

[0061] For this, please refer to Figure 2 , Figures 8-9 As shown, this application further proposes a fully automatic feeding laser cutting machine, whose suction mechanism 9 includes the following improvements: an adjustment waist hole 951 is provided on the suction support plate 95, two sets of adjustment screws 96 are slidably provided at the adjustment waist hole 951, two sets of locking nuts 961 are threadedly connected to the adjustment screws 96, the two sets of locking nuts 961 are respectively located at the upper and lower ends of the suction support plate 95, the suction head 97 is fixedly installed at the lower end of the adjustment screw 96, the upper parts of multiple sets of adjustment screws 96 located on the same side are connected by a linkage plate 98, and an adjustment drive 99 for driving the suction heads 97 on both sides to adjust the relative distance is fixedly provided at the upper end of the suction base plate 94, so as to adapt to the suction or clamping of different workpieces.

[0062] Through the above technical solution, this application provides an adjustable suction head mechanism, effectively solving the problems of poor adaptability and the need for manual intervention to adjust or replace parts caused by the fixed position of the suction head in traditional suction mechanisms when handling workpieces of different sizes. Specifically, the adjusting waist hole 951 provides a sliding installation space for the adjusting screw 96, which, together with the locking nut 961, allows the position of the suction head 97 to be flexibly adjusted and reliably fixed. Multiple sets of adjusting screws 96 located on the same side are connected by a linkage plate 98, ensuring that the suction head 97 can move synchronously during adjustment, maintaining the stability and uniformity of suction. Furthermore, the introduction of the adjusting drive 99 enables the relative spacing of the suction heads 97 to be automatically adjusted without manual intervention, greatly improving the automation level and ease of operation of the equipment. This adjustable suction clamping method allows the suction mechanism 9 to quickly and accurately adapt to workpieces of different specifications, thereby significantly improving the processing efficiency and flexibility of the fully automatic feeding laser cutting machine when handling diverse workpieces, and reducing labor costs and labor intensity.

[0063] In some of the embodiments described above in this application, an adjustment drive is proposed to drive the two adsorption heads to adjust the relative distance, thereby adapting to the adsorption or clamping of different workpieces. However, in the implementation process, the adjustment mechanism may lack precise synchronous control, resulting in inaccurate adjustment of the adsorption head distance or low efficiency, affecting the loading and unloading speed and adaptability.

[0064] For this, please refer to Figure 2 , Figures 8-9 As shown, this application further proposes an adjustment drive 99, which includes an adjustment guide rail 993 fixedly mounted on the upper end of the suction seat plate 94. An adjustment slider 994 is slidably connected to the adjustment guide rail 993. A slider pin 995 is fixedly mounted at the upper center of the adjustment slider 994. Two sets of drive connecting rods 996 are rotatably connected to the slider pin 995. A connecting pin 981 rotatably connected to the drive connecting rods 996 is fixedly mounted on the linkage plate 98. An adjustment vertical plate 991 is fixedly mounted at one end of the adjustment guide rail 993. An adjustment telescopic cylinder 992 is fixedly mounted on the adjustment vertical plate 991. The output end of the adjustment telescopic cylinder 992 is fixedly connected to the adjustment slider 994.

[0065] Through the above technical solution, this application provides a precise and synchronous adjustment mechanism for the spacing between the adsorption heads. The extension and retraction of the telescopic cylinder 992 directly drives the adjusting slider 994 to move linearly along the adjusting guide rail 993. Since the slider pin 995 is located at the center of the adjusting slider 994, and the two sets of driving linkages 996 are symmetrically rotated and connected to the connecting pin 981 on the slider pin 995 and the linkage plate 98, the linear movement of the adjusting slider 994 can be precisely converted into the synchronous movement of the linkage plate 98 through the driving linkages 996. The linkage plate 98 then drives the adsorption heads 97 on both sides to adjust the relative spacing at the same speed and stroke, thereby ensuring that the adsorption heads 97 always maintain symmetry during the adjustment process and avoiding clamping instability or positioning deviation caused by asynchrony. This structure not only improves the adaptability efficiency for workpieces of different sizes and reduces the time and error of manual adjustment, but also achieves high-precision synchronous control through mechanical linkage, significantly improving the flexibility and automation level of the fully automatic loading laser cutting machine when handling diverse workpieces, thereby optimizing the overall loading and unloading speed and cutting efficiency.

[0066] The following example will provide a more detailed explanation of the above technical solution: In a production workshop, a batch of metal sheets needs to be laser-cut. Traditionally, workers manually load the sheets onto the cutting machine and then manually unload them after cutting, which is not only labor-intensive but also limits production efficiency. This embodiment provides a fully automated feeding laser cutting machine that effectively solves the above problems.

[0067] First, the metal sheet to be processed is placed on the feeding conveyor belt 2 set on the main frame 1. When the feeding conveyor belt 2 transports the sheet to the preset loading position, the fully automatic loading laser cutting machine begins to perform automated loading operation. Two sets of loading mechanisms 8 are fixedly set on the upper end of the main frame 1. The suction mechanism 9 on one of the loading mechanisms 8 will be activated. The suction mechanism 9 includes a suction lifting cylinder 91 fixedly installed vertically upward on the loading slide 86, and a lifting plate 92 fixedly installed at its output end. A vertically downward rotary motor 93 is fixedly installed on the lifting plate 92, and a suction seat plate 94 is fixedly installed on the output shaft of the rotary motor 93. Multiple suction support plates 95 are fixedly set at the lower end of the suction seat plate 94, and suction heads 97 for adsorbing or clamping workpieces are installed on the suction support plates 95. To accommodate boards of different sizes, the suction support plate 95 is equipped with an adjustment waist hole 951. Two sets of adjustment screws 96 are slidably installed at the adjustment waist hole 951, and the suction head 97 is fixedly installed at the lower end of the adjustment screw 96. An adjustment drive 99 is fixedly installed at the upper end of the suction base plate 94. The adjustment drive 99 includes an adjustment telescopic cylinder 992, whose output end drives the linkage plate 98 through the adjustment slider 994, slider pin 995 and drive connecting rod 996, thereby adjusting the relative distance between the two suction heads 97 to ensure stable adsorption of the current board.

[0068] The suction lifting cylinder 91 descends, causing the suction head 97 to contact and adhere to the sheet material on the feeding conveyor belt 2. Subsequently, the suction lifting cylinder 91 rises, lifting the sheet material away from the feeding conveyor belt 2. At this time, the feeding drive 6 starts working, driving the suction mechanism 9 to slide back and forth on the feeding mechanism 8. The feeding motor 62 in the feeding drive 6 drives the connecting shaft 65 to rotate via belt drive 64. The connecting shaft 65 then drives the feeding slider 85 to slide on the feeding guide rail 82 via the feeding pulley 83 and the feeding belt 84, thereby driving the suction mechanism 9 to move horizontally. The suction mechanism 9 moves the adhered sheet material from above the feeding conveyor belt 2 to above the cutting table 4 on the cutting frame 3, and then descends to place the sheet material on the cutting table 4.

[0069] After the sheet material is properly placed, the cutting mechanism 5 begins laser cutting. The cutting mechanism 5 includes a cutting bracket 51 fixedly mounted on the upper end of the cutting frame 3. A threaded screw 53 is rotatably mounted on the upper part of the cutting bracket 51, and the cutting motor 52 drives the threaded screw 53 to rotate. A cutting slide 55 is threaded through the threaded screw 53 and slides on the cutting guide rod 54. A translation slide 56 is perpendicular to the moving direction of the cutting slide 55, and a lifting cylinder 57 is fixedly mounted at its lower end. A laser cutter 58 is fixedly mounted at the output end of the lifting cylinder 57. The cutting motor 52 drives the cutting slide 55 to move in the X direction, the translation slide 56 to move in the Y direction, the lifting cylinder 57 adjusts the height of the laser cutter 58, and the laser cutter 58 precisely cuts the sheet material according to a preset program.

[0070] After cutting is completed, the suction mechanism 9 on another set of feeding mechanisms 8, or the same set of suction mechanisms 9, is activated again to pick up the cut workpiece. The suction mechanism 9 lifts the workpiece from the cutting table 4 and moves it horizontally above the feeding conveyor belt 2. It then lowers the workpiece and places it on the feeding conveyor belt 2, which then transports the finished workpiece out of the cutting area.

[0071] The innovation of this embodiment lies in its highly efficient linkage mechanism 7. The linkage mechanism 7 is fixedly mounted on the linkage base 71 at the upper end of the main frame 1 and connected to connecting shaft 65 and connecting shaft 66 via bearing support 714. The linkage mechanism 7 enables independent or synchronous rotation of connecting shaft 65 and connecting shaft 66. When the two sets of suction mechanisms 9 need to simultaneously load and unload workpieces, the electric push rod 78 retracts, driving the two ends of the drive rod 751 to insert into the drive hole 741 of shaft 74 and the connecting hole 761 of shaft 76, respectively. At this time, connecting shaft 65 drives shaft 74 to rotate via gears 72 and 73, and drives shaft 76 to rotate synchronously via drive rod 751. Shaft 76 then drives connecting shaft 66 via belt drive 77. Due to the meshing transmission of gears 72 and 73, the rotation directions of connecting shaft 65 and connecting shaft 66 are opposite, thus causing the two sets of suction mechanisms 9 to move in opposite directions. This means that while one set of suction mechanisms 9 is feeding uncut sheet metal into the cutting table 4, another set of suction mechanisms 9 can simultaneously remove the cut workpiece from the cutting table 4 and send it back to the feeding conveyor belt 2. This synchronous feeding and discharging working mode significantly reduces the loading and unloading time and greatly improves the overall processing efficiency of the laser cutting machine compared to the existing technology that requires waiting for one process to be completed before proceeding to the next.

[0072] When only one set of suction mechanism 9 is needed to load or unload workpieces, the electric push rod 78 extends, driving drive rod 751 to move towards shaft 74, causing drive rod 751 to insert into drive hole 741 and separate from connecting hole 761. At this time, drive rod 751 and drive rod 753 are rotatably connected through connecting bearing 752, and the rotation of shaft 74 will not synchronously drive shaft 76 to rotate, thus realizing the operation of a single loading mechanism 8 and suction mechanism 9.

[0073] Through the above-mentioned automated and synchronized design, this fully automatic feeding laser cutting machine eliminates the need for manual loading and unloading, effectively reducing labor intensity and labor costs. Furthermore, through the coordinated work of the two sets of suction mechanisms 9, especially the synchronous loading and unloading, production efficiency is greatly improved, solving the shortcomings of existing laser cutting machines in terms of automated loading.

[0074] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
