Description

Technical Field

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

[0002] Laser cutting machines, as crucial equipment in modern manufacturing, are gradually replacing traditional mechanical cutting methods and are widely favored due to their unique advantages. Unlike traditional mechanical tools, laser cutting machines utilize laser technology for cutting, eliminating the need for molds, significantly reducing cutting force, minimizing the heat-affected zone and deformation, resulting in smoother cuts, higher precision, and faster cutting speeds. Furthermore, the flexibility and automatic layout of laser cutting patterns significantly improves material utilization and reduces processing costs, making it an important tool for driving the upgrading of the manufacturing industry. However, in actual use, the limited speed of the laser cutting head along the X-axis hinders the improvement of cutting efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a laser cutting machine that addresses the problem of limited speed of the laser cutting head on the X-axis in existing laser cutting machines, which makes it difficult to improve cutting efficiency.

[0004] The technical solution is as follows:

[0005] On one hand, a laser cutting machine is provided, comprising a frame, a crossbeam that moves and cooperates with the frame in a first direction, a slide mounted on the crossbeam and moving and cooperates with the crossbeam in a second direction, a mounting plate mounted on the slide and moving and cooperates with the slide in a third direction, a first driving mechanism, a second driving mechanism, a third driving mechanism, a stacking driving mechanism, and a laser cutting head. The first driving mechanism is drivenly connected to the crossbeam and is used to drive the crossbeam to move in the first direction. The second driving mechanism is drivenly connected to the slide and is used to drive the slide to move in the second direction. The third driving mechanism is drivenly connected to the mounting plate and is used to drive the mounting plate to move in the third direction. The stacking driving mechanism is mounted on the mounting plate and is drivenly connected to the laser cutting head. The stacking driving mechanism is used to drive the laser cutting head to move in the first direction, wherein any two of the first direction, the second direction, and the third direction are perpendicular to each other.

[0006] In the laser cutting machine described in the above embodiments, when the length of the cutting pattern on the workpiece along the first direction is within the stroke range of the superimposed driving mechanism, the first driving mechanism is not activated. The second driving mechanism and the superimposed driving mechanism cooperate to drive the laser cutting head to move, and the moving area can completely cover the outline of the cutting pattern, ensuring that the laser cutting head can cut the corresponding cutting pattern on the workpiece. At the same time, since the superimposed driving mechanism consumes less energy than the first driving mechanism, it is more energy-efficient and environmentally friendly. When the length of the cutting pattern on the workpiece along the first direction exceeds the stroke range of the superimposed driving mechanism, both the first driving mechanism and the superimposed driving mechanism are activated, and cooperate with the second driving mechanism to drive the laser cutting head to move. This allows the laser cutting head to reach the cutting speed faster in both the first and second directions, improving cutting efficiency. At the same time, the average load of the first driving mechanism, the second driving mechanism, and the superimposed driving mechanism decreases, reducing energy consumption and making it more energy-efficient and environmentally friendly. Compared with existing laser cutting machines, this application adds a superimposed drive mechanism. When the superimposed drive mechanism is started, it only needs to drive the laser cutting head. The drive load is light, and it has high acceleration and high jerk during safe operation. It has low energy consumption, flexible operation, and smooth movement. When both the superimposed drive mechanism and the first drive mechanism are started to perform coaxial superposition, the laser cutting head can reach the cutting speed faster in the first and second directions, shortening the start-up time, shortening the crossing time of the cutting pattern, shortening the braking time, and improving the cutting efficiency.

[0007] The technical solution will be further explained below:

[0008] In one embodiment, the length of the cutting pattern on the workpiece to be cut along the first direction is set as a first length. When the first length is within the stroke range of the superimposed driving mechanism, the superimposed driving mechanism is activated and the first driving mechanism is not activated. When the first length exceeds the stroke range of the superimposed driving mechanism, both the superimposed driving mechanism and the first driving mechanism are activated.

[0009] In one embodiment, the superimposed driving mechanism includes a mounting body mounted on the mounting plate and a driving module mounted on the mounting body. The driving module is connected to the laser cutting head and is used to drive the laser cutting head to move along the first direction.

[0010] In one embodiment, the mounting body includes a first mounting section and a second mounting section arranged at an angle. The first mounting section is fixed to the mounting plate, the second mounting section is located on the side of the first mounting section away from the mounting plate and is connected to one end of the first mounting section, and the laser cutting head is located on the side of the second mounting section near the other end of the first mounting section.

[0011] In one embodiment, the drive module includes a linear motor with a first output shaft connected to the mounting body. The linear motor and the mounting body move in coordination along the first direction, and the laser cutting head is mounted on the linear motor.

[0012] In one embodiment, the drive module includes a drive component, a transmission assembly, and a mounting base. The mounting base is movable and engaged with the mounting body along the first direction. The laser cutting head is mounted on the mounting base. The drive component is mounted on the mounting body and is drivenly connected to the transmission assembly. The transmission assembly is drivenly connected to the mounting base so that the laser cutting head can be driven to reciprocate along the first direction via the mounting base.

[0013] In one embodiment, the driving component includes a servo motor with a second output shaft, and the transmission assembly includes a transmission gear sleeved on the second output shaft and a transmission rack arranged along the first direction and mounted on the mounting base, wherein the transmission gear meshes with the transmission rack.

[0014] In one embodiment, the drive unit further includes a geared motor with a third output shaft, the second output shaft being drively connected to the geared motor, and the transmission gear being sleeved on the third output shaft.

[0015] In one embodiment, the drive module further includes a transmission screw that is pulsatorically connected to the transmission assembly and a transmission female sleeve mounted on the mounting base. The transmission screw is arranged along the first direction and rotatably connected to the mounting body. The transmission female sleeve is fitted onto the transmission screw and cooperates with the transmission screw to form a screw-nut structure.

[0016] In one embodiment, the driving component includes a drive motor with a fourth output shaft, and the transmission assembly includes a driving wheel, a driven wheel, and a timing belt. The driving wheel is sleeved on the fourth output shaft, the driven wheel is sleeved on the transmission screw, and the timing belt is sleeved on the outer side wall of the driving wheel and the outer side wall of the driven wheel.

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] like Figure 1As shown, in one embodiment, a laser cutting machine 10 is provided, including a frame (not shown), a crossbeam 100 that moves with the frame in a first direction, a slide 200 mounted on the crossbeam 100 and moving with the crossbeam 100 in a second direction, a mounting plate 300 mounted on the slide 200 and moving with the slide 200 in a third direction, a first drive mechanism (not shown), a second drive mechanism 400, a third drive mechanism 500, a stacking drive mechanism 600, and a laser cutting head 700. The first drive mechanism is drivenly connected to the crossbeam 100 and is used to drive the crossbeam 100 to move in the first direction. The second drive mechanism 400 is drivenly connected to the slide 200 and is used to drive the slide 200 to move in the second direction. The third drive mechanism 500 is drivenly connected to the mounting plate 300 and is used to drive the mounting plate 300 to move in a third direction. The stacking drive mechanism 600 is mounted on the mounting plate 300 and is drivenly connected to the laser cutting head 700. The superimposed drive mechanism 600 is used to drive the laser cutting head 700 to move along a first direction. Any two of the first direction, the second direction, and the third direction are perpendicular to each other.

[0028] It should be noted that in existing laser cutting machines, the laser cutting head 700 is mounted on the mounting plate 300. When the first drive mechanism drives the laser cutting head 700 to move along the first direction, the entire driven component (including the crossbeam 100 and all components on the crossbeam 100) is heavy, resulting in low acceleration and jerk during safe operation, slow speed, and high power consumption. It requires significant effort to increase the speed at which the laser cutting head 700 moves along the first direction. In other words, the speed bottleneck of the laser cutting head 700 moving along the first direction has become a key factor hindering the improvement of cutting efficiency. In contrast, the laser cutting machine 10 of this application has a superimposed drive mechanism 600 mounted on the mounting plate 300 and connected to the laser cutting head 700. When the superimposed drive mechanism 600 drives the laser cutting head 700 to move along the first direction, the entire driven component (only the laser cutting head 700) is lightweight, allowing for high allowable acceleration and jerk during safe operation, resulting in fast speed and low power consumption.

[0029] In the laser cutting machine 10 described above, when the length of the cutting pattern on the workpiece along the first direction is within the travel range of the superimposed driving mechanism 600, the first driving mechanism is not activated. The second driving mechanism 400 and the superimposed driving mechanism 600 cooperate to drive the laser cutting head 700 to move, and the moving area can completely cover the outline of the cutting pattern, ensuring that the laser cutting head 700 can cut the corresponding cutting pattern on the workpiece. At the same time, since the superimposed driving mechanism 600 has lower energy consumption than the first driving mechanism, it is more energy-efficient and environmentally friendly. When the length of the cutting pattern on the workpiece along the first direction exceeds the travel range of the superimposed driving mechanism 600, both the first driving mechanism and the superimposed driving mechanism 600 are activated, and cooperate with the second driving mechanism 400 to drive the laser cutting head 700 to move, so that the laser cutting head 700 can reach the cutting speed faster in the first and second directions, improving cutting efficiency. At the same time, the average load of the first driving mechanism, the second driving mechanism 400, and the superimposed driving mechanism 600 decreases, energy consumption decreases, and it is more energy-efficient and environmentally friendly. Compared with existing laser cutting machines, this application adds a superimposed drive mechanism 600. When the superimposed drive mechanism 600 is started, it only needs to drive the laser cutting head 700. The drive load is light, and the acceleration is large during safe operation. It has low energy consumption, flexible operation, and smooth movement. When both the superimposed drive mechanism 600 and the first drive mechanism are started to perform coaxial superposition, the laser cutting head 700 can reach the cutting speed faster in the first and second directions, shortening the start-up time, shortening the crossing time of the cutting pattern, shortening the braking time, and improving the cutting efficiency.

[0030] Specifically, in this embodiment, the length of the cutting pattern on the workpiece to be cut along the first direction is set as the first length. When the first length is within the stroke range of the superimposed driving mechanism 600, the superimposed driving mechanism 600 is started and the first driving mechanism is not started. When the first length exceeds the stroke range of the superimposed driving mechanism 600, both the superimposed driving mechanism 600 and the first driving mechanism are started.

[0031] Specifically, the moving speed of the laser cutting head 700 relative to the crossbeam 100 along the first direction is set to V. T The speed at which the crossbeam 100 moves relative to the frame in the first direction is set to V. B The speed at which the laser cutting head 700 moves relative to the frame along the first direction is set to V. R When the length of the cutting pattern on the workpiece along the first direction is within the stroke range of the superimposed drive mechanism 600, the first drive mechanism is not activated, the superimposed drive mechanism 600 is activated, and the laser cutting head 700 moves relative to the frame along the first direction at a speed V. R =V TWhen the length of the cutting pattern on the workpiece along the first direction exceeds the travel range of the superimposed drive mechanism 600, both the first drive mechanism and the superimposed drive mechanism 600 are activated, and the laser cutting head 700 moves relative to the frame at a speed V along the first direction. R =V T +V B .

[0032] It should be noted that the stroke range of the superimposed drive mechanism 600 can be flexibly adjusted according to actual usage needs.

[0033] Specifically, in this embodiment, the first direction can be set as the direction in which the workpiece to be cut is transported to the laser cutting machine 10, and the third direction can be set as the vertical direction.

[0034] The movement and engagement of the crossbeam 100 with the frame along the first direction, the movement and engagement of the slide block 200 with the crossbeam 100 along the second direction, and the movement and engagement of the mounting plate 300 with the slide block 200 along the third direction can all be achieved through a sliding rail and slider engagement, a slider and slide groove engagement, or other movable engagement methods. The first drive mechanism can be any existing drive structure capable of driving the crossbeam 100 to reciprocate relative to the frame along the first direction. The second drive mechanism 400 can be any existing drive structure capable of driving the slide block 200 to reciprocate on the crossbeam 100 along the second direction. The third drive structure can be any existing drive structure capable of driving the mounting plate 300 to reciprocate on the slide block 200 along the third direction.

[0035] like Figure 2 As shown, in this specific embodiment, a comparative cutting test was conducted between an existing laser cutting machine and the laser cutting machine 10 of this application. The results of the test were analyzed and compared. It can be seen that compared with the laser cutting machine in the prior art, the cutting time of the laser cutting machine 10 of this application is reduced by more than 20%, and the cutting efficiency is significantly improved.

[0036] like Figure 1 and Figure 3 As shown, in one embodiment, the stacking drive mechanism 600 includes a mounting body 610 mounted on a mounting plate 300 and a drive module 620 mounted on the mounting body 610. The drive module 620 is drively connected to the laser cutting head 700 and is used to drive the laser cutting head 700 to move along a first direction. Thus, the drive module 620 can be first mounted on the mounting body 610 and then mounted on the mounting plate 300 via the mounting body 610, improving the ease of assembly of the laser cutting machine 10.

[0037] The stacking drive mechanism 600 can be mounted on the mounting body 610 by snap-fit, plug-in, screw-in, or other means. The mounting body 610 can be mounted on the mounting plate 300 by snap-fit, plug-in, screw-in, or other means.

[0038] like Figure 3 As shown, optionally, the mounting body 610 includes a first mounting section 611 and a second mounting section 612 arranged at an angle. The first mounting section 611 is fixed to the mounting plate 300. The second mounting section 612 is located on the side of the first mounting section 611 away from the mounting plate 300 and is connected to one end of the first mounting section 611. The laser cutting head 700 is located on the side of the second mounting section 612 near the other end of the first mounting section 611. In this way, the superimposed drive mechanism 600, the mounting body 610, and the laser cutting head 700 are integrated, reducing the risk of interference with surrounding objects and also facilitating the miniaturization of the laser cutting machine 10.

[0039] In this specific embodiment, the first mounting section 611 and the second mounting section 612 are arranged perpendicularly and integrally formed.

[0040] like Figure 1 and Figure 3 As shown, optionally, the drive module 620 includes a linear motor 621 with a first output shaft. The first output shaft is connected to the mounting body 610. The linear motor 621 and the mounting body 610 move in a first direction. The laser cutting head 700 is mounted on the linear motor 621. In this way, the mounting body 610 can guide the linear motor 621, ensuring that the linear motor 621 can stably and reliably drive the laser cutting head 700 to reciprocate along the first direction, thereby improving the cutting quality of the laser cutting machine 10.

[0041] Specifically, in this embodiment, the stacking drive mechanism 600 further includes a first guide rail and a first slider that slides with the first guide rail. The first guide rail is fixed to the mounting body 610 along a first direction, and the first slider is fixedly connected to the linear motor 621. In other embodiments, the first guide rail can be replaced by a first groove that slides with the first slider.

[0042] like Figure 1 and Figure 4As shown, in one embodiment, the drive module 620 includes a drive component 622, a transmission assembly 623, and a mounting base 624. The mounting base 624 is movable and engaged with the mounting body 610 along a first direction. The laser cutting head 700 is mounted on the mounting base 624. The drive component 622 is mounted on the mounting body 610 and is driveably connected to the transmission assembly 623. The transmission assembly 623 is driveably connected to the mounting base 624, so that the laser cutting head 700 can be driven to reciprocate along the first direction via the mounting base 624. In this way, the drive component 622 can drive the mounting base 624 via the transmission assembly 623, while the mounting body 610 can guide the mounting base 624, so that the mounting base 624 can stably and reliably drive the laser cutting head 700 to reciprocate along the first direction, thereby improving the cutting quality of the laser cutting machine 10.

[0043] Specifically, in this embodiment, the stacking drive mechanism 600 further includes a second guide rail and a second slider that slides with the second guide rail. The second guide rail is fixed to the mounting body 610 along a first direction, and the second slider is fixedly connected to the mounting base 624. In other embodiments, the second guide rail can be replaced by a second sliding groove that slides with the second slider.

[0044] like Figure 1 and Figure 4 As shown, the drive component 622 further includes a servo motor 6221 with a second output shaft. The transmission assembly 623 includes a transmission gear 6231 sleeved on the second output shaft and a transmission rack 6232 arranged along the first direction and mounted on the mounting base 624. The transmission gear 6231 meshes with the transmission rack 6232. Thus, the transmission gear 6231 and the transmission rack 6232 cooperate to form a gear and rack structure, thereby stably and reliably transmitting the driving force of the servo motor 6221 to the mounting base 624, ensuring that the mounting base 624 can smoothly reciprocate along the first direction, and improving the reliability of the laser cutting machine 10.

[0045] like Figure 1 and Figure 4 As shown, optionally, the drive unit 622 also includes a geared motor 6222 with a third output shaft. The second output shaft is connected to the geared motor 6222 in a transmission manner. A transmission gear 6231 is sleeved on the third output shaft. In this way, the geared motor 6222 can convert the high-speed rotation of the servo motor 6221 into a low-speed output to match the moving speed of the laser cutting head 700 along the first direction. At the same time, by reducing the speed, the output torque is increased, ensuring that the superimposed drive mechanism 600 can drive the laser cutting head 700, thereby improving the reliability of the laser cutting machine 10.

[0046] like Figure 1 and Figure 5As shown, in one embodiment, the drive module 620 further includes a transmission screw 6251 connected to the transmission assembly 623 and a transmission sleeve 6252 mounted on the mounting base 624. The transmission screw 6251 is arranged along a first direction and is rotatably connected to the mounting body 610. The transmission sleeve 6252 is sleeved on the transmission screw 6251 and cooperates with the transmission screw 6251 to form a screw-nut structure. In this way, the screw-nut structure can convert the rotational motion of the drive member 622 into the linear motion required by the mounting base 624, and can also precisely control the moving speed and position of the laser cutting head 700 by controlling the number of rotations of the transmission screw 6251, thereby improving the practicality of the laser cutting machine 10.

[0047] The transmission component 623 can be configured as a gear transmission structure, belt transmission structure, chain transmission structure or other transmission structure.

[0048] like Figure 1 and Figure 5 As shown, optionally, the drive component 622 includes a drive motor with a fourth output shaft. The transmission assembly 623 includes a drive wheel 6233, a driven wheel 6234, and a timing belt 6235. The drive wheel 6233 is sleeved on the fourth output shaft. The driven wheel 6234 is sleeved on the transmission screw 6251. The timing belt 6235 is sleeved on the outer side wall of the drive wheel 6233 and the outer side wall of the driven wheel 6234. Thus, the drive motor drives the drive wheel 6233 to rotate, and the drive wheel 6233 drives the driven wheel 6234 to rotate via the timing belt 6235. The driven wheel 6234 drives the screw and nut structure to move, and the screw and nut structure converts the rotational motion into linear motion and drives the mounting base 624 to move, thereby causing the mounting base 624 to drive the laser cutting head 700 to reciprocate along the first direction.
