Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a laser cutting device. Background Technology

[0002] Composite materials are mostly composed of fibers and a matrix. During production, storage, and transportation, they are prone to deformation problems such as warping, shifting, and surface unevenness due to factors such as internal stress release and external compression. If the material cannot be effectively shaped and stably held throughout the feeding and cutting process, it will directly affect the cutting accuracy and cut quality. However, most current cutting equipment only has a simple guide groove or a single pressing structure at the feeding end. This can only provide preliminary guidance for the material and cannot correct warping and shifting caused by stress release and equipment vibration during material transportation in real time. This results in unstable posture of the material when it arrives at the cutting station, leading to decreased cutting accuracy and poor cut quality, which seriously affects the processing effect and production efficiency. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a laser cutting device, which aims to solve the problem that existing cutting devices cannot effectively shape and stably hold materials when processing composite materials.

[0004] This application provides a laser cutting device, including a cutting mechanism, the cutting mechanism comprising:

[0005] The rack has a first direction, a second direction, and a third direction that are perpendicular to each other;

[0006] A cutting assembly includes a first linear motion unit, a second linear motion unit, a moving frame, and a cutting component. The first linear motion unit is mounted on the frame and is used to drive the moving frame to move back and forth along the first direction. The second linear motion unit is mounted on the moving frame and is used to drive the cutting component to move back and forth along the second direction.

[0007] A shaping assembly includes a shaping plate and a plurality of first shaping units. The shaping plate is mounted on the movable frame along the first direction, and a shaping channel extending along the first direction is formed on the shaping plate. The plurality of first shaping units are spaced apart on the shaping plate along the first direction, and each first shaping unit has a shaping component located above the shaping channel. The arc-shaped shaping surface of the shaping component is in elastic contact with the upper surface of the cutting material. The cutting component is located on the side near the discharge end of the shaping channel and is used to cut the material.

[0008] In one possible implementation, the first shaping unit includes a first fixed base, a first guide frame, a first elastic element, and at least one first guide shaft. The first fixed base is mounted on the shaping plate and has a first passage space for the cutting material to pass through. The first guide frame is slidably disposed in the first passage space along the third direction. The first guide shaft is connected to the first guide frame along the second direction, and a shaping element is rotatably sleeved on each of the first guide shafts. The first elastic element is disposed in the first passage space along the third direction, and one end of the first elastic element is connected to the inner top surface of the first fixed base, and the other end is connected to the top surface of the first guide frame.

[0009] In one possible implementation, the first guide frame includes a top plate and two side plates, the two side plates are spaced apart along the second direction, one end of the side plate near the top plate is fixedly connected to the top plate, the first guide shaft is connected between the two side plates, and the surface of the top plate opposite to the side plates is connected to the first elastic element.

[0010] Each of the two opposing surfaces of the side plates is provided with a slider, and the inner wall of the first fixing seat is provided with a groove that cooperates with the slider, the groove extending along the third direction.

[0011] In one possible implementation, the cutting mechanism further includes a protective cover and a dust collection box.

[0013] The laser cutting equipment also includes a controller, which is electrically connected to the first linear motion unit, the second linear motion unit, and the length measuring component. The controller is configured to receive data transmitted by the length measuring component and calculate the feed length of the cutting material. When the feed length of the cutting material reaches a preset cutting length threshold, the controller controls the first linear motion unit to drive the moving frame to move along the first direction according to the real-time feed speed of the cutting material, and simultaneously controls the second linear motion unit to drive the cutting piece to move along the second direction to complete the cutting of the material.

[0014] In one possible implementation, the length measuring assembly includes an encoder, a measuring wheel, a connecting arm, and a mounting base. The mounting base is fixed to the shaping plate and located on one side of the shaping channel. One end of the connecting arm is rotatably connected to the mounting base, and the other end is fixed with the encoder. The encoder is electrically connected to the controller, and the rotating end of the encoder passes through the connecting arm and is connected to the measuring wheel. The measuring wheel is used to contact the surface of the material being cut.

[0015] In one possible implementation, the cutting mechanism further includes a guide assembly comprising two guide bars spaced apart along the first direction at the discharge end of the forming channel, and each of the two guide bars having an extension portion extending from one side close to the other, the extension portion having a guide channel communicating with the forming channel, and the projection of the laser cutting head of the cutting element being located between the two extension portions.

[0016] In one possible implementation, the cutting mechanism further includes a discharge detection component, which includes a connecting seat, a sensing wheel, a detector, a rotating shaft, a connecting strip, a detection plate, and a reset elastic element.

[0017] The connecting seat is located at the end of the guide channel away from the shaping plate. The rotating shaft is rotatably passed through the connecting seat along the second direction. One end of the connecting strip is connected to one end of the rotating shaft. The sensing wheel is rotatably connected to the other end of the connecting strip. The reset elastic element is wound around the rotating shaft, and one end of the reset elastic element is connected to the connecting seat, and the other end is connected to the connecting strip. When the sensing wheel is not under the pressure of the cutting material, the reset elastic element drives the connecting strip and the detection piece to reset to the initial position.

[0018] The detection piece and the detector are located on the same side of the connecting seat away from the sensing wheel. The detector has a sensing position. The detection piece is connected to the other end of the rotating shaft, and the detection piece can extend into or out of the sensing position as the rotating shaft rotates.

[0019] In one possible implementation, the discharge detection assembly further includes an upper limit member and a lower limit member. A connecting block is sleeved on the end of the rotating shaft away from the connecting strip. One end of the detection piece is connected to the connecting block. The upper limit member and the lower limit member are respectively disposed on both sides of the connecting block in the third direction to limit the movement range of the connecting block in the third direction.

[0020] In one possible implementation, the shaping assembly further includes a second shaping unit, which includes a fixing plate, a second fixing seat, a second guide frame, a second elastic element, and at least one second guide shaft.

[0021] The fixing plate is disposed between the guide strip and the connecting seat, and the fixing plate has a passageway along the first direction, the passageway connecting the guide channel. The second fixing seat is mounted on the fixing plate, and the second fixing seat has a second passageway for the cutting material to pass through. The second guide frame is slidably disposed in the second passageway along the third direction. The second guide shaft is connected to the second guide frame along the second direction, and a shaping member is rotatably sleeved on each of the second guide shafts. The second elastic member is disposed in the second passageway along the third direction, and one end of the second elastic member is connected to the inner top surface of the second fixing seat, and the other end is connected to the top surface of the second guide frame.

[0022] The technical solutions provided in this application have the following advantages compared with the prior art:

[0023] By setting a shaping channel on the shaping plate to limit and guide the sides of the cutting material, and in conjunction with multiple first shaping units on the shaping plate, each first shaping unit applies pressure to the upper surface of the cutting material, gradually correcting the bent or twisted material to a relatively flat state. The shaped material then enters the cutting area, where the cutting element can cut it at the precise location, effectively avoiding the decrease in cutting accuracy and damage to the cutting element caused by material deformation, further ensuring the stability and reliability of the entire laser cutting process. Furthermore, during the cutting process, the shaping element constantly presses against the upper surface of the cutting material, continuously limiting its movement and preventing deviation or jitter, thereby further improving cutting accuracy and stability.

[0038] Figure 1 This is a schematic diagram of the structure of an embodiment of the laser cutting equipment of the present invention; Figure 2 This is a top view schematic diagram of an embodiment of the laser cutting equipment of the present invention.

[0039] like Figure 1 and Figure 2As shown, this embodiment provides a laser cutting device, which includes a cutting mechanism 10, an air booster 30, and a chiller 40. The cutting mechanism 10 is used to cut the material, and it can complete the cutting task according to a preset trajectory and parameters. The air booster 30 provides stable and suitable gas pressure for the cutting process, ensuring smooth cutting, and the gas pressure can be adjusted according to the cutting requirements of different materials. The chiller 40 serves a cooling function, preventing damage to the equipment due to high temperatures during the cutting process and ensuring stable operation of the equipment over a long period. It should be noted that the cooperation between the air booster 30, the chiller 40, and the cutting mechanism 10 is common knowledge to those skilled in the art and will not be described in detail here.

[0040] In this embodiment, to facilitate the description of the positional relationships of the components, a first direction X, a second direction Y, and a third direction Z are defined. Specifically, the frame 11 is used as a reference datum, meaning that the frame 11 has two mutually perpendicular first directions X, second directions Y, and third direction Z. Here, the first direction X is the length direction of the frame 11, the second direction Y is the width direction of the frame 11, and the third direction Z is the height direction of the frame. Furthermore, in this embodiment, "up" refers to the direction on the third direction Z that is away from the bottom of the frame 11, and "down" refers to the direction on the third direction Z that is closer to the bottom of the frame 11.

[0041] Figure 3 This is a schematic diagram of the cutting mechanism in one embodiment of the laser cutting equipment of the present invention.

[0042] Specifically, such as Figure 3 As shown, the cutting mechanism 10 includes a frame 11, a cutting assembly 12, and a shaping assembly 13. The cutting assembly 12 includes a second linear motion unit 123, a moving frame 122, and a cutting piece 124. The second linear motion unit 123 is mounted on the moving frame 122 and is used to drive the cutting piece to move back and forth along the second direction Y. The shaping assembly 13 includes a shaping plate 131, which is mounted on the moving frame 122 along the first direction X. The shaping plate 131 has a shaping channel (not shown) extending along the first direction X. The shaping channel has an inlet end and an outlet end, and the cutting piece 124 is located on the side near the outlet end of the shaping channel. The cutting material 20 is fed into the shaping channel from the inlet end and exits from the outlet end, thus passing through the shaping channel. Figure 2 and Figure 3 S represents the feeding direction.

[0043] In other words, when cutting begins, the cutting material 20 extends into the shaping channel from the feed end. Once the input cutting material reaches a preset length, the second linear motion unit 123 drives the cutting element 124 to move along the second direction Y to cut the cutting material 20. After cutting, the cutting material continues to be fed. When the fed cutting material 20 reaches the preset length again, the second linear motion unit 123 is activated again to drive the cutting element 124 to move along the second direction Y for cutting. This cycle repeats continuously, achieving continuous, efficient, and precise cutting of the material. Furthermore, the cut segments are continuously pushed towards the discharge end as the cutting material 20 is continuously fed in, causing the cut material to exit the shaping channel for collection. The entire process requires no manual intervention, achieving an automated production process. Simultaneously, the equipment is equipped with an intelligent sensing system that can monitor the remaining amount of cutting material 20 in real time and automatically issue an alarm when the material is about to run out, reminding the operator to replenish it in time, ensuring the continuity and stability of the cutting operation.

[0044] For example, in traditional laser cutting equipment, the cutting part 124 is fixed to the frame. Cutting can only be performed after the material has been fed to a preset length and feeding has stopped. This is intermittent cutting, which is not only inefficient, but also prone to positional deviation of the cutting material during start-up and stop. Furthermore, if the feed speed of the cutting material changes, the fixed cutting part 124 cannot adapt, which can easily lead to problems such as cutting position deviation and irregular cuts, and cannot achieve dynamic following cutting.

[0045] To address the inability to achieve dynamic following during cutting, the laser cutting equipment also includes a first linear motion unit 121, mounted on the frame 11, which drives the moving frame 122 to move back and forth along the first direction X. In practical applications, initially, the cutting material 20 is continuously and automatically pushed into the shaping channel along the first direction X by the feeding mechanism. At this time, the shaping channel remains in a fixed position with the moving frame 122, and the cutting material 20 and the shaping channel generate continuous relative feeding motion, causing the shaping channel to continuously shape the cutting material 20 and regularize its shape. When the cutting material 20 is fed to the cutting position and cutting is required, the first linear motion unit 121 drives the moving frame 122 to move synchronously along the first direction X according to the real-time feeding speed, so that the shaping channel and the cutting channel move back and forth along the first direction X. The cutting component 124 and the cutting material 20 move synchronously in the same direction and at the same speed. During this synchronous movement, the cutting component 124 performs the cutting action on the cutting material while the two are relatively stationary. At this time, the shaping channel still shapes and constrains the cutting material, and the continuous shaping action is not interrupted. After the cutting is completed, the first linear motion unit 121 drives the moving frame 122, the shaping channel, and the cutting component 124 to reset along the first direction X, waiting for the next cutting command. At the same time, the cutting material continues to be fed, entering the next cycle of "shaping-synchronous cutting-reset". In this way, no matter how the feeding speed of the cutting material 20 changes, the cutting component 124 can cut the cutting material 20 at the optimal position, realizing dynamic following cutting, which greatly improves cutting efficiency and cutting quality.

[0046] It should be noted that both the first linear motion unit 121 and the second linear motion unit 123 in the above embodiments can adopt a high-precision lead screw and servo motor structure to ensure that the moving frame 122 and the cutting piece 124 have extremely high positioning accuracy and repeatability during movement, thereby ensuring the accuracy and consistency of cutting. Furthermore, the servo motor has the characteristics of fast response speed and high control precision, and can quickly adjust the speed and direction according to the instructions of the control system to achieve precise movement of the cutting piece 124 in the first direction X and the second direction Y. In addition, the cutting piece 124 is a laser cutting head, which has a high energy density laser beam emission capability, enabling rapid and precise cutting of various materials.

[0047] In practical applications, the cutting material 20 is prone to deformation such as bending and twisting during production, storage, and transportation due to factors such as internal stress release and external compression. If the deformed cutting material 20 is cut directly, the cutting accuracy will be greatly reduced, and the cut part may even be damaged. To this end, the shaping assembly 13 further includes a plurality of first shaping units 132, which are installed at intervals along a first direction on the shaping plate 131, and each first shaping unit 132 has a shaping component 134 located above the shaping channel. In other words, when the cutting material 20 is fed into the shaping channel, it will pass through multiple first shaping units 132 in sequence. The shaping component 134 of each first shaping unit 132 will apply a certain pressure to the upper surface of the cutting material 20, and cooperate with the side walls of the shaping channel to limit and guide the side of the cutting material, thereby gradually correcting the bent and twisted cutting material 20 to a relatively flat state. After the cutting material 20 is shaped, it enters the cutting area. At this time, the cutting component 124 can cut it at the accurate position, effectively avoiding the problem of reduced cutting accuracy and damage to the cutting component caused by material deformation, and further ensuring the stability and reliability of the entire laser cutting process.

[0048] It should be noted that the term "multiple" mentioned above refers to two or more, and the specific number can be set according to the actual situation. Preferably, in this embodiment, there are three first shaping units 132, forming preliminary shaping, secondary shaping, and tertiary shaping, thereby ensuring that the cutting material 20 can achieve a high degree of flatness. In actual operation, the preliminary shaping stage mainly corrects large-scale bending or twisting of the material, laying the foundation for subsequent fine shaping; the secondary shaping stage further refines the correction effect, eliminating any minor deformations that may remain after the preliminary shaping; the tertiary shaping stage serves as the final guarantee, ensuring that the cutting material reaches the optimal flatness state before entering the cutting area. This not only improves shaping efficiency but also significantly enhances shaping quality, providing a strong guarantee for subsequent laser cutting operations.

[0049] In summary, the laser cutting equipment of this application, by setting a shaping channel on the shaping plate 131 to limit and guide the side of the cutting material 20, and in conjunction with multiple first shaping units 132 set on the shaping plate 131, uses the shaping component 134 of each first shaping unit 132 to apply a certain pressure to the upper surface of the cutting material 20, so as to gradually correct the bent and twisted cutting material to a relatively flat state. After the cutting material is shaped, it enters the cutting area, at which time the cutting component 124 can cut it at the accurate position, effectively avoiding the problem of decreased cutting accuracy and damage to the cutting component caused by material deformation, and further ensuring the stability and reliability of the entire laser cutting process. In addition, during the cutting process, the shaping component 134 always presses the upper surface of the cutting material 20, which can continuously limit the cutting material 20 and prevent it from shifting or shaking during the cutting process, thereby further improving the cutting accuracy and stability.

[0050] Figure 4 This is a schematic diagram of the structure of the first shaping unit in one embodiment of the laser cutting equipment of the present invention.

[0051] like Figure 4 As shown, in one possible implementation, the first shaping unit 132 includes a first fixed base 1321, a first guide frame 1322, a first elastic element 1323, and at least one first guide shaft 1324. The first fixed base 1321 is mounted on the shaping plate 131 and has a first passage space for the cutting material 20 to pass through. The first guide frame 1322 is slidably disposed in the first passage space along the third direction Z. The first guide shaft 1324 is connected to the first guide frame 1322 along the second direction Y, and a shaping element 134 is rotatably sleeved on each first guide shaft 1324. The first elastic element 1323 is disposed in the first passage space along the third direction Z, and one end of each first elastic element 1323 is connected to the inner top surface of the first fixed base 1321, and the other end is connected to the top surface of the first guide frame 1322.

[0052] In other words, when the cutting material 20 enters the shaping channel, its bent or twisted parts will first contact the shaping component 134. As the cutting material continues to be fed in, the shaping component 134 is pushed by the cutting material 20 and moves along the third direction Z. Since the shaping component 134 is connected to the first guide shaft 1324, and the first guide shaft 1324 is connected to the first guide frame 1322, and the first guide frame 1322 is slidably disposed in the first passage space, the movement of the shaping component 134 will drive the first guide... The frame 1322 slides along the third direction Z in the first passage space. At the same time, the first elastic element 1323 is compressed and generates elastic force. This elastic force will react on the first guide frame 1322 and the shaping element 134, so that the shaping element 134 generates a continuous and stable pressure on the cutting material 20. At this time, as the cutting material 20 is fed in, the bent and twisted cutting material 20 is gradually corrected to a relatively flat state, thereby ensuring that the cutting material 20 remains flat in the shaping channel, preparing for subsequent precise cutting.

[0053] In addition, such as Figure 4 As shown, a first adjusting member 1325 is provided on the top of the first fixed base 1321 along the third direction Z. One end of the first adjusting member 1325 passes through the top of the first fixed base 1321 and extends into the first passage space to connect with the first guide frame 1322. In specific implementation, the first adjusting member 1325 can be adjusted by a thread. By rotating the first adjusting member 1325, the position of the first guide frame 1322 in the first passage space can be precisely controlled, thereby adjusting the pressure of the shaping member 134 on the cutting material 20. In this way, the pressure of the shaping member can be flexibly adjusted according to the characteristics of different cutting materials 20 and the required flatness requirements, ensuring that the cutting material 20 can achieve the best correction effect and meet diverse cutting needs.

[0054] Specifically, such as Figure 4 As shown, the first guide frame 1322 includes a top plate 13221 and two side plates 13222. The two side plates 13222 are spaced apart along the second direction Y. One end of the side plate 13222 near the top plate 13221 is fixedly connected to the top plate 13221. A first guide shaft 1324 is connected between the two side plates 13222. The surface of the top plate 13221 facing away from the side plates 13222 is connected to the first elastic element 1323. Each of the opposing surfaces of the two side plates 13222 is provided with a slider (not shown). The inner wall of the first fixed seat 1321 has a groove that cooperates with the slider, extending along the third direction Z. In other words, the first guide frame 1322 achieves stable sliding along the third direction Z within the first travel space through the cooperation of the slider and the groove. This not only ensures the smooth movement of the first guide frame 1322 but also improves its movement accuracy and stability, thereby ensuring the uniformity and consistency of the pressure applied by the shaping element 134 to the cutting material 20.

[0055] Furthermore, since the two side plates 13222 of the first guide frame 1322 are connected by a first guide shaft 1324, and a shaping component 134 is rotatably fitted on each first guide shaft 1324, the shaping component 134 can rotate slightly around the first guide shaft 1324 when it is pushed by the cutting material 20, so that the shaping component 134 can better adapt to the surface shape of the cutting material 20, thereby improving the correction effect and cutting accuracy.

[0056] Figure 6 This is a schematic diagram of the structure of the second shaping unit, the guiding component, and the dust collection box in one embodiment of the laser cutting equipment of the present invention.

[0057] During the cutting process, sparks and dust are generated, reducing visibility in the working environment. Furthermore, the sparks can pose a safety hazard to operators. Therefore, such as... Figure 3 and Figure 6 As shown, in one possible implementation, the cutting mechanism further includes a protective cover 16, which is installed on the outer periphery of the laser cutting head of the cutting element 124 to effectively block sparks from splashing, preventing sparks from injuring operators around the equipment and reducing the spread of smoke and dust. In addition, the cutting mechanism also includes a dust collection box 17, which is located on the side of the protective cover 16 away from the cutting element 124 and is connected to the protective cover 16. In this way, the dust collection box 17 can promptly remove the smoke and dust generated during the cutting process, reducing the pollution of the working environment and ensuring that operators can work in a relatively clean and safe environment, further improving the safety and stability of the laser cutting equipment.

[0058] like Figure 1 and Figure 3As shown, in one possible implementation, the cutting mechanism further includes a length measuring component 14, which is located between a first shaping unit 132 and a cutting piece 124 near the feed end of the shaping channel. The laser cutting equipment also includes a controller, which is electrically connected to the first linear motion unit 121, the second linear motion unit 123, and the length measuring component 14. The controller is configured to receive data transmitted by the length measuring component 14 and calculate the feed length of the cutting material. When the feed length of the cutting material 20 reaches a preset cutting length threshold, the controller controls the first linear motion unit 121 to drive the moving frame 122 to move along the first direction X according to the real-time feed speed of the cutting material, and simultaneously controls the second linear motion unit 123 to drive the cutting piece 124 to move along the second direction Y, so as to complete the cutting of the cutting material 20. In other words, when the feed length of the cutting material 20 into the shaping channel reaches the preset cutting length threshold, the cutting action begins. At this time, the first linear motion unit 121 is controlled to drive the moving frame 122 to move synchronously along the first direction X according to the real-time feed speed, so that the shaping channel, the cutting component 124, and the cutting material 20 move synchronously at the same speed and in the same direction in the first direction X. At the same time, the second linear motion unit 123 is controlled to drive the cutting component 124 to move along the second direction Y to dynamically follow and cut the cutting material 20. After the cutting is completed, the first linear motion unit 121 drives the moving frame 122, the shaping channel, and the cutting component 124 to reset along the first direction X, waiting for the next cutting command. Meanwhile, the cutting material 20 continues to be fed, entering the next cycle of "shaping-synchronous cutting-reset". In this way, through the cooperation of the length measuring component 14 and the controller, the accurate measurement and automatic control of the feed length of the cutting material 20 are realized, effectively avoiding the problem of inaccurate cutting length caused by manual measurement errors or untimely operation, and improving cutting efficiency and cutting quality.

[0059] Figure 5 This is a schematic diagram of the length measuring component in one embodiment of the laser cutting equipment of the present invention.

[0060] Specifically, such as Figure 5As shown, the length measuring assembly 14 includes an encoder 144, a measuring wheel 145, a connecting arm 143, and a mounting base 141. The mounting base 141 is fixed on the shaping plate 131 and located on one side of the shaping channel. One end of the connecting arm 143 is rotatably connected to the mounting base 141 via a connecting shaft 142, and the other end is fixed with the encoder 144. The encoder 144 is electrically connected to the controller, and the rotating end of the encoder 144 passes through the connecting arm 143 and is connected to the measuring wheel 145. The measuring wheel 145 is used to contact the surface of the cutting material 20. That is, when the cutting material 20 moves, it will drive the measuring wheel 145 to rotate. The rotation of the measuring wheel 145 will be transmitted to the encoder 144. The encoder 144 converts the rotation of the measuring wheel 145 into an electrical signal and transmits it to the controller. The controller calculates the feed length of the cutting material 20 based on the received electrical signal, thereby enabling real-time measurement of the feed length of the cutting material 20 and providing reliable data support for subsequent precise cutting.

[0061] In addition, the surface of the measuring wheel 145 is knurled to increase the friction between the measuring wheel and the cutting material 20, prevent slippage during the measurement process, ensure that the measuring wheel 145 can rotate stably as the cutting material 20 moves, thereby ensuring that the rotation signal received by the encoder 144 is accurate and improving the accuracy of the feed length measurement.

[0062] like Figure 6 As shown, in one possible implementation, the cutting mechanism 10 further includes a guide assembly, which includes two guide bars 19. The two guide bars 19 are spaced apart along the first direction X at the discharge end of the forming channel, and each of the two guide bars 19 extends an extension 191 on the side that is close to each other. The extension 191 has a guide channel 191a that communicates with the forming channel, and the projection of the laser cutting head of the cutting member 124 is located between the two extensions 191. In other words, after the material 20 is shaped by the shaping channel, it exits from the discharge end and enters the guide channel 191a. Since both guide bars 19 have extensions 191 on their adjacent sides, and these extensions 191 have guide channels 191a, the material 20 is limited and guided by the guide channels 191a when it exits. This ensures that the material 20 maintains a stable linear motion before entering the cutting area, preventing positional shifts or inaccurate trajectories from affecting cutting accuracy. This ensures the material 20 accurately enters the cutting area along a preset path, laying the foundation for subsequent precise cutting. Simultaneously, the projection of the laser cutting head of the cutting component 124 is located between the two extensions, allowing the laser cutting head to accurately align with the material 20, avoiding cutting errors caused by material 20 shifting or jitter, further improving cutting accuracy and stability.

[0063] In actual production, the cutting material 20 may not be completely cut, causing it to stick together or become impossible to separate during subsequent processing. This not only affects product quality but may also hinder the production process. Therefore, as... Figure 1 and Figure 3 As shown, in one possible implementation, the cutting mechanism 10 further includes a discharge detection component 15, which is used to detect whether the cutting material 20 is completely cut. The discharge detection component 15 can be positioned at a suitable location behind the discharge end of the forming channel. It can detect the physical properties of the cutting material 20 through specific detection methods, such as using sensors to detect the integrity and continuity of the cutting material 20. When it is detected that the cutting material 20 is not completely cut, the discharge detection component 15 will promptly send a signal. This signal can be transmitted to the equipment's control system. After receiving the signal, the control system will take corresponding measures according to a preset program, such as pausing equipment operation or issuing an alarm to remind the operator, so that the operator can promptly handle the uncut material, avoiding problems such as adhesion or inability to separate, thereby ensuring product quality and the smooth operation of the production process.

[0064] Figure 7 This is a schematic diagram of the output detection component in one embodiment of the laser cutting equipment of the present invention; Figure 8 This is a schematic diagram of the output detection component from another perspective in one embodiment of the laser cutting equipment of the present invention.

[0065] Specifically, such as Figure 7 and Figure 8 As shown, the discharge detection assembly 15 includes a connecting seat 151, a sensing wheel 154, a detector 156, a rotating shaft 152, a connecting strip 153, a detection piece 157, and a reset elastic element 155. The connecting seat 151 is located at the end of the guide channel away from the shaping plate 131. The rotating shaft 152 is rotatably passed through the connecting seat 151 along the second direction Y. One end of the connecting strip 153 is connected to one end of the rotating shaft 152. The sensing wheel 154 is rotatably connected to the other end of the connecting strip 153. The reset elastic element 155 is wound around the rotating shaft 152, and one end of the reset elastic element 155 is connected to the connecting seat 151, and the other end is connected to the connecting strip 153. When the sensing wheel 154 is not under pressure from the material being cut, the reset elastic element 155 drives the connecting strip 153 and the detection piece 157 to return to their initial positions. The detection piece 157 and the detector 156 are located on the same side of the connecting seat 151 away from the sensing wheel 154. The detector 156 is provided with a sensing position 156a. The detection piece 157 is connected to the other end of the rotating shaft, and the detection piece 157 can extend into or out of the sensing position 156a as the rotating shaft 152 rotates.

[0066] In other words, when the cutting material 20 extends from the guide channel, its lower surface contacts the sensing wheel. At this time, the sensing wheel 154 is subjected to downward pressure due to the weight of the cutting material 20. After the sensing wheel 154 is subjected to pressure, it will drive the connecting bar 153 to rotate around the rotating shaft 152. The rotation of the connecting bar 153 will cause the rotating shaft 152 to rotate accordingly. The rotation of the rotating shaft 152 will then drive the detection piece 157 to rotate, causing the detection piece 157 to extend into the sensing position 156a of the detector 156. This will trigger the detector 156 and output a material detection signal. When the material has completely passed through the sensing wheel 154, the sensing wheel 154 loses the pressure of the cutting material. Under the action of the reset elastic element 155, the connecting bar 153 and the rotating shaft 152 will be reset in the opposite direction, causing the detection piece to disengage from the sensing position 156a. At this time, the material detection signal of the detector 156 is interrupted. The next section of the cutting material 20 will then contact the sensing wheel 154 again, repeating the above "signal triggering-signal interruption" process, thus determining that the material has been effectively cut. If the cutting material 20 is not cut, it will remain in continuous, elongated form, in constant contact with the induction wheel 154 and apply pressure. During this time, the induction wheel 154, under continuous pressure, causes the detection plate 157 to remain within the sensing position 156a of the detector 156, resulting in the detector 156 continuously outputting a material detection signal without interruption. This process indicates that the cutting material 20 has not been effectively cut. Thus, by observing the changes in the output signal of the detector 156, it is possible to accurately and efficiently determine whether the cutting material has been effectively cut. This provides a reliable basis for the normal operation of the laser cutting equipment and the monitoring of cutting quality, effectively avoiding a series of problems that may be caused by uncut material and ensuring the stability and accuracy of the entire cutting process.

[0067] In addition, the cutting mechanism also includes a laser detection element 18, which is located between the guide assembly and the discharge detection assembly 15. This element detects the state of the material 20 after laser cutting and determines whether it has been effectively cut. Specifically, the laser detection element 18 emits a laser beam and receives the reflected laser signal, analyzing the cutting state of the material 20 based on the signal intensity and changes. When the material 20 is effectively cut, the reflected signal received by the laser detection element 18 undergoes a specific change, triggering a corresponding judgment mechanism. When the material 20 is not cut, the reflected signal remains relatively stable, allowing the laser detection element 18 to issue a timely warning so that the operator can adjust the parameters of the laser cutting equipment or take other appropriate measures.

[0068] Therefore, the synergistic effect of the laser detection component 18 and the discharge detection component 15 enables comprehensive monitoring of the cutting status of the cutting material 20. Specifically, the cutting material 20 first passes through the laser detection component 18, which emits a laser beam towards the material and receives the reflected laser signal. The intensity and changes of the signal are then analyzed to determine the cutting status of the material 20. If it is determined that the material 20 is completely cut, it is pushed into the discharge detection component 15, where the material is finally confirmed after cutting. The two components work together to ensure the accuracy and reliability of the cutting results. In this way, if a cutting abnormality is detected, the equipment can react quickly, avoiding the production of defective products and improving production efficiency and product quality.

[0069] like Figure 8 As shown, in one possible implementation, the discharge detection assembly 15 further includes an upper limit member 158 and a lower limit member 159. A connecting block 1510 is sleeved on the end of the rotating shaft 152 away from the connecting strip. One end of the detection piece 157 is connected to the connecting block 1510. The upper limit member 158 and the lower limit member 159 are respectively located on both sides of the connecting block 1510 in the third direction Z, used to limit the movement range of the connecting block 1510 in the third direction Z. Thus, when the cutting material 20 completes cutting and triggers the discharge action, the rotating shaft 152 drives the connecting block 1510, the connecting block 1510, and the detection piece 157 to rotate synchronously. During rotation, the detection piece 157 passes through a specific detection area. At this time, the upper limit member 158 and the lower limit member 159, by limiting the movement range of the connecting block 1510, indirectly ensure the positional accuracy of the detection piece 157 within the detection area. This enables the discharge detection assembly 15 to reliably detect the material state after cutting, providing a strong guarantee for the stable operation and high-quality cutting of the entire laser cutting equipment.

[0070] In actual production, after the cutting process, the edges of the material 20 are prone to warping, bending, or localized bulging deformation. If it directly enters the discharge inspection stage, the irregular shape will lead to unstable contact pressure with the induction wheel, and may even cause false triggering due to non-cutting adhesion. Therefore, if... Figure 6As shown, in one possible implementation, the shaping component 13 further includes a second shaping unit 133, which includes a fixing plate 1331, a second fixing seat 1332, a second guide frame 1333, a second elastic element 1334, and at least one second guide shaft 1335. A fixing plate 1331 is disposed between the guide strip 19 and the connecting seat 151, and the fixing plate 1331 has a passageway along the first direction X, which connects to the guide channel. The second fixing seat 1332 is installed on the fixing plate 1331, and the second fixing seat 1332 has a second passageway for the cutting material 20 to pass through. The second guide frame 1333 is slidably disposed in the second passageway along the third direction Z. The second guide shaft 1335 is connected to the second guide frame 1333 along the second direction Y, and a shaping member 134 is rotatably sleeved on each second guide shaft 1335. The second elastic member 1334 is disposed in the second passageway along the third direction Z, and one end of the second elastic member 1334 is connected to the inner top surface of the second fixing seat 1332, and the other end is connected to the top surface of the second guide frame 1333.

[0071] In other words, when the cutting material 20 passes through the second passage space, the second guide frame 1333, under the action of the second elastic element 1334, will apply a certain pressure to the cutting material 20 along the third direction Z. At this time, the shaping element 134, which is rotatably sleeved on the second guide shaft 1335, will contact the upper surface of the cutting material 20 and make adaptive adjustments according to the shape of the edge of the cutting material 20, thereby eliminating deformations such as warping, bending or local protrusions, making the cutting material 20 flat and smooth, and able to stably contact the induction wheel, ensuring the accuracy and reliability of the material output detection process.

[0072] Furthermore, a second adjusting member 1336 is provided on the top of the second fixed base 1332 along the third direction Z. One end of the second adjusting member 1336 passes through the top of the second fixed base 1332 and extends into the second passage space to connect with the second guide frame 1333. In this way, the pressure of the shaping member 134 can be flexibly adjusted according to the characteristics of different cutting materials 20 and the required flatness, ensuring that the cutting material 20 can achieve the best correction effect and meet diverse cutting needs.

[0073] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
