After the air pump is started, the air intake pipe of the air pump uses the connecting pipe to transport the air inside the collection box from the bottom to the outside, and a negative pressure environment is generated inside the collection box. Under the action of the negative pressure environment, the airflow near the cutting station above the collection box is prompted to move downward and enter the collection box from the feed hole, which is conducive to the debris generated by the cutting entering the collection box with the airflow and being collected, thereby preventing the debris generated by the cutting from randomly splashing and adhering to the clamping parts, thereby affecting the clamping stability of the subsequent clamping parts on the workpiece to be processed, and further affecting the laser cutting effect. The randomly splashing debris also seriously increases the difficulty of cleaning for the staff; the set conical mesh cover is convenient for blocking the debris entering the collection box, preventing the debris from entering the connecting pipe and the air pump with the airflow. During the cutting process, the second motor is started, and the output shaft of the second motor will drive the scraper to rotate. During the rotation, the scraper will scrape the debris attached to the surface of the conical mesh cover, thereby preventing the debris from adhering to the conical mesh cover for a long time, causing blockage of the conical mesh cover, thereby affecting the fluidity of the airflow. 3. The storage shell is set at the bottom of the laser head. When the laser head moves significantly along the Y-axis direction to adjust the cutting position, it is conducive to synchronously driving the storage shell to move, and with the help of the cooperation of the sliding plate and the vertical plate, the rectangular plate is pulled to move synchronously, thereby ensuring that as long as the feed hole near the laser head is in an open state, the concentration and efficiency of debris absorption are further improved. Therefore, when the laser head cuts at different positions along the length direction of the workpiece, the position of the airflow barrier and the flow conditions of the feed holes below are automatically adjusted dynamically, thereby improving the adaptability of debris collection.

DETAILED DESCRIPTION

[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] Application scenarios: Existing cutting technology may not be easy to adapt according to material properties, which makes it difficult to optimize the cutting effect for different materials, affecting processing quality and efficiency. At the same time, the debris generated during laser cutting is easy to splash and difficult to be collected. If the splashed debris adheres to the clamping part, it is easy to affect the stability of the clamping part in clamping the workpiece, which not only affects the processing accuracy, but may also cause safety hazards and environmental pollution problems.

[0029] like Figures 1 to 9 The laser cutting device for drawer slides shown in the figure comprises a cutting platform 1, a gantry 2 is slidably connected to the side wall of the cutting platform 1, and is characterized in that it also comprises: The laser head 3 is connected to the top of the gantry 2 by sliding the sliding block transversely; The plane displacement mechanism is used to drive the laser head 3 to move in the XY plane; Two clamping members are symmetrically arranged on the top of the cutting platform 1 and are used to clamp the workpiece to be processed; An installation opening is provided through the top of the cutting platform 1, a collecting box 4 with a box door is fixedly installed on the inner wall of the installation opening, and a plurality of feeding holes 5 are provided through the top of the collecting box 4 in a linear array; A negative pressure component is arranged inside the collecting box 4 and is used to absorb the debris generated by laser cutting into the collecting box 4 through the feeding hole 5 by means of negative pressure; A material identification unit, used to identify the material information of the workpiece to be processed; The control unit controls the laser head 3 and the plane displacement mechanism to adjust the cutting parameters and the operation of the negative pressure component according to the material information identified by the material identification unit; During operation, the workpiece to be processed into a drawer slide is placed on two clamping members with the help of an external manipulator, and the ends of the workpiece to be processed are clamped with the help of the two clamping members, which is conducive to maintaining the stability of the placement of the workpiece to be processed during the subsequent laser cutting process. The material type of the clamped workpiece to be processed is identified by the material identification unit. The control unit adjusts the laser head 3 to the corresponding cutting parameters according to the identified material type. The cutting parameters of the laser head 3 include but are not limited to power, focus position, perforation parameters, etc. The plane displacement mechanism is adjusted to the corresponding displacement trajectory and speed. The displacement trajectory set in advance by the plane displacement mechanism can drive the laser head 3 to move in the XY plane to ensure the flexibility and accuracy of laser cutting, so as to complete the cutting of the corresponding shape of the workpiece to be processed. The set negative pressure component is adjusted to the corresponding negative pressure power according to the material type, so that a negative pressure environment is formed inside the collection box 4, which is conducive to the cutting debris generated at the cutting station entering the collection box 4 from the feed hole 5 with the airflow and being collected, effectively solving the problem of debris splashing and difficulty in centralized collection. The box door set in the collection box 4 is convenient for subsequent staff to open the box door to clean up the debris in the collection box 4 uniformly; The material recognition unit can accurately identify the material information of the workpiece to be processed, providing a basis for subsequent parameter adjustment. The control unit automatically adjusts the cutting parameters of the laser head 3 and the plane displacement mechanism according to the identified material information, and adjusts the operating state of the negative pressure component at the same time. This intelligent adjustment ensures that the cutting parameters and negative pressure intensity are adapted to the material characteristics, greatly improving the cutting effect and efficiency, and effectively solving the problem that the traditional laser cutting equipment needs to manually adjust the parameters when facing the workpieces to be processed of drawer guides of different materials; The clamping member includes a mounting frame 9, which is fixedly mounted on the top of the cutting platform 1. Electric push rods 10 are symmetrically fixedly connected to the side walls of the mounting frame 9, and the piston rod ends of the electric push rods 10 are fixedly connected to clamping plates 11. When working, the two clamping plates 11 are pushed toward each other by starting the electric push rods 10 on both sides of the mounting frame 9, and the ends of the workpiece to be processed are clamped by means of the two movable clamping plates 11, thereby improving the stability of the placement of the workpiece to be processed during the subsequent laser cutting process, and avoiding the situation where the laser cutting path affects the cutting shape due to the displacement of the workpiece to be processed.

[0030] In actual application, when a new drawer slide material is placed on the cutting platform 1 and fixed by the clamp, the material identification unit will first perform material analysis. Assuming that the material is identified as stainless steel, the control unit will immediately call the preset stainless steel cutting parameters, including laser power, cutting speed, etc. At the same time, according to the characteristics of the debris generated during stainless steel cutting, the control unit will adjust the suction of the negative pressure component accordingly to ensure the best debris collection effect. With the start of the cutting process, the laser head 3 moves precisely along the preset trajectory under the control of the plane displacement mechanism, and the debris generated by the cutting will be sucked into the collection box 4 in time, effectively preventing the debris from splashing and accumulating. For different material types The control unit can adjust the parameters in real time to ensure the consistency of cutting quality; compared with traditional laser cutting equipment, the solution of the present application has significant advantages. First, it can automatically adjust the cutting parameters according to the drawer slides of different materials, which greatly improves the adaptability and efficiency of processing. Secondly, it is collected through the negative pressure component, which effectively solves the problem of debris splashing, improves the quality of the working environment and processing stability. Finally, the introduction of the intelligent control system makes the entire cutting process more precise and controllable, and reduces human operation errors. It not only improves production efficiency and product quality, but also reduces operation difficulty and maintenance costs, providing strong support for the precision and diversified production of drawer slides.

[0031] As an embodiment of the present invention, the plane displacement mechanism includes: Two electric cylinders 6 are symmetrically fixedly installed on both sides of the cutting platform 1, and the piston rod ends of the two electric cylinders 6 are fixedly connected to the side walls of the gantry 2; A threaded sleeve, fixedly embedded on the sliding block; The first motor 7 is fixedly installed on the top of the gantry 2, and the end of the output shaft of the first motor 7 is fixedly connected with a threaded rod 8, and the threaded rod 8 is threadedly connected to the threaded sleeve. When working, the electric cylinder 6 and the first motor 7 are started by the control unit, and the gantry 2 provided with the laser head 3 is pushed to move by the piston rod of the electric cylinder 6, thereby driving the laser head 3 to move along the direction of the X-axis. When the first motor 7 is operating, the output shaft of the first motor 7 drives the threaded rod 8 to rotate. Since the threaded rod 8 is threadedly connected to the threaded sleeve embedded in the sliding block, during the rotation of the threaded rod 8, with the help of the transmission of the threaded sleeve, the laser head 3 can be driven to move along the direction of the Y-axis. Therefore, with the cooperation of the electric cylinder 6 and the first motor 7, the laser head 3 is driven to move in the XY plane, thereby completing the cutting of the corresponding shape of the workpiece to be processed.

[0032] As an embodiment of the present invention, the negative pressure component includes: The air pump 12 is fixedly mounted at the bottom of the collecting box 4. The end of the air inlet pipe of the air pump 12 is fixedly connected with a connecting pipe 13. The end of the connecting pipe 13 is connected with the inside of the collecting box 4. The conical mesh cover 14 is fixedly mounted on the inner bottom surface of the collecting box 4 to block the debris from protecting the pipe opening of the connecting pipe 13. The top of the conical mesh cover 14 is fixedly connected to a protection box, and a second motor 15 is arranged inside the protection box. The output shaft of the second motor 15 passes through the box cover of the protection box and extends upward to be fixedly connected to a scraper 16. The scraping surface of the scraper 16 is adapted to the inclined surface on the conical mesh cover 14. During operation, when the workpieces of different materials are cut by laser, the sizes of the debris generated are usually different. In order to save energy, the air pump 12 is adjusted to the corresponding working power to absorb the debris generated by the cutting. After testing in advance, each is set in the control unit. The air pump 12 operation parameters corresponding to the material are as follows. After the air pump 12 is started, the air inlet pipe of the air pump 12 transports the air inside the collection box 4 from the bottom to the outside with the help of the connecting pipe 13. A negative pressure environment is generated inside the collection box 4. Under the effect of the negative pressure environment, the airflow near the cutting station above the collection box 4 is prompted to move downward and enter the collection box 4 from the feed hole 5, which is conducive to the debris generated by the cutting entering the collection box 4 with the airflow and being collected, thereby preventing the debris generated by the cutting from randomly splashing and adhering to the clamping parts, thereby affecting the clamping stability of the subsequent clamping parts on the workpiece to be processed, and further affecting the laser cutting effect. In addition, the randomly splashing debris also seriously increases the difficulty of cleaning for the staff. The conical mesh cover 14 is provided to conveniently block the debris entering the collection box 4, and prevent the debris from entering the connecting pipe 13 and the air pump 12 along with the airflow. During the cutting process, the second motor 15 is started, and the output shaft of the second motor 15 drives the scraper 16 to rotate. The scraper 16 scrapes the debris attached to the surface of the conical mesh cover 14 during the rotation, thereby preventing the debris from being attached to the conical mesh cover 14 for a long time, causing blockage of the conical mesh cover 14, and affecting the fluidity of the airflow.

[0033] As an embodiment of the present invention, the negative pressure assembly further includes a centralized absorption component, which includes an airflow downward blowing mechanism and multiple groups of transverse blocking mechanisms, wherein the multiple groups of transverse blocking mechanisms are distributed in a linear array along the Y-axis direction, and each group of transverse blocking mechanisms is used to block the feed holes 5 that are close to each other in the X-axis direction; The airflow downward blowing mechanism includes a drainage box 17 and a storage shell 18 with a clearance port. The drainage box 17 is fixedly installed on the cutting platform 1. The side wall of the drainage box 17 is fixedly connected to the air outlet pipe of the air pump 12. The storage shell 18 is fixedly installed on the lower side wall of the laser head 3. The clearance port is used for the laser diode on the laser head 3 to pass through. The side wall of the storage shell 18 is fixedly connected with a hose 20. The end of the hose 20 is fixedly connected to the top of the drainage box 17. The bottom of the storage shell 18 is provided with a circular port 19. The centralized absorption component also includes an L-shaped plate 21, which is slidably connected to the cutting platform 1 in the Y-axis direction, and a rectangular plate 22 is fixedly connected to the end of the L-shaped plate 21. The two ends of the rectangular plate 22 are symmetrically provided with inclined surfaces 2201. The top of the L-shaped plate 21 is symmetrically fixedly connected to two vertical plates 23. The side walls of the two vertical plates 23 are penetrated with sliding openings. The inner walls of the two sliding openings are slidably connected with sliding plates 24. The ends of the two sliding plates 24 are fixedly connected to the side walls of the storage shell 18. In the process of the rectangular plate 22 moving along the Y-axis direction, the inclined surface 2201 is used to release the multiple groups of horizontal blocking mechanisms from the corresponding feed holes. 5 is blocked; during operation, since the workpiece to be processed of the guide rail usually has a certain length, the laser head 3 will cut the workpiece at different positions, and the multiple feed holes 5 set on the top of the collection box 4 are prone to cause negative pressure dispersion, which expands the range of debris splashing. When cutting the edge of the clamping piece, the risk of debris adhering to the clamping piece is increased. Therefore, by setting the drainage box 17, the drainage box 17 is connected with the air outlet pipe of the air pump 12, so that the airflow drawn from the collection box 4 is transported to the drainage box 17, and is preferentially transmitted to the storage shell 18 by means of the hose 20, so as to realize the recycling of the airflow, and the airflow entering the storage shell 18 is discharged from the bottom circle The shaped opening 19 flows downward, and a downward annular airflow barrier is formed under the storage shell 18, which enhances the debris absorption effect, and the airflow barrier moves with the position of the laser head 3. Under the action of the annular airflow barrier, the debris splashing outward can be blocked, the range of debris splashing can be reduced, and the possibility of debris adhering to the clamping member can be reduced. In addition, multiple groups of transverse blocking mechanisms are set to block several feed holes 5. As the laser head 3 moves along the Y-axis direction, the two sliding plates 24 are driven to move by the storage shell 18. The two sliding plates 24 cooperate with the two vertical plates 23 to pull the rectangular plate 22 connected thereto. The L-shaped plate 21 moves along the Y-axis direction. During the movement of the rectangular plate 22, the inclined surface 2201 provided on the side wall of the rectangular plate 22 will release the blocking of the corresponding feed hole 5 by the transverse blocking mechanism located below the rectangular plate 22, thereby restoring the fluidity of the feed hole 5 around the laser head 3, avoiding the dispersion of the suction airflow, and facilitating the airflow around the laser head 3 to enter the collection box 4 with the aid of the feed hole 5 with restored fluidity. The negative pressure environment in the collection box 4 absorbs the airflow of the cutting station, and the airflow barrier ejected from the circular opening 19 at the bottom of the storage shell 18, under the guidance of the double airflow, is further conducive to facilitating the smooth entry of debris into the collection box 4; Since the workpiece to be processed is relatively long, the storage shell 18 is set at the bottom of the laser head 3. When the laser head 3 moves significantly along the Y-axis direction to adjust the cutting position, it is beneficial to synchronously drive the storage shell 18 to move, and with the help of the cooperation of the sliding plate 24 and the vertical plate 23, the rectangular plate 22 is pulled to move synchronously, thereby ensuring that as long as the feed hole near the laser head 3 is in an open state, the concentration and efficiency of debris absorption are further improved. Therefore, when the laser head 3 cuts different positions in the length direction of the workpiece to be processed, the position of the airflow barrier and the flow conditions of the surrounding feed holes 5 are automatically adjusted dynamically, thereby improving the adaptability of debris collection, and the sliding plate 24 and the inside of the sliding port are set to be slidingly connected in the X-axis direction, so that the storage shell 18 can move slightly along the X-axis direction with the laser head 3.

[0034] As an embodiment of the present invention, each transverse blocking mechanism includes: Two mounting grooves are symmetrically arranged on the inner wall of the collecting box 4. A sliding box 25 is vertically slidably connected to the inner walls of the two mounting grooves. A plurality of sealing plates 26 are fixedly installed on the top of the sliding box 25 in a linear array along the X-axis direction. The plurality of sealing plates 26 are used to block the corresponding feed holes 5 in the X-axis direction. A sealing gasket is connected to the surface of each sealing plate 26. A hemisphere 27 is fixedly connected to the top of each sealing plate 26. Two gas springs 28 are symmetrically fixedly mounted on the inner wall of the collecting box 4, and the piston rod ends of the two gas springs 28 are fixedly connected to the bottom of the sliding box 25; A circular hole 29 is formed through the top of the collecting box 4; The cylinder 30 is fixedly connected to the top of the sliding box 25. The upper end of the cylinder 30 passes through the circular hole 29 and extends upward to the outside thereof and is fixedly connected to a mounting seat. The inner wall of the circular hole 29 is in sealing contact with the cylinder 30 through a sealing gasket. A ball 31 is rotatably connected to the inner wall of the mounting seat through a rotating shaft. The surface of the ball 31 and the inclined surface 2201 are adapted to each other. When working, the sliding box 25 is supported by the gas spring 28 to facilitate supporting the sealing plate 26 to the corresponding feed hole 5 to ensure the sealing of the feed hole 5. When the rectangular plate 22 moves along the Y-axis direction with the laser head 3, the inclined surface 2201 on the side wall of the rectangular plate 22 will press the surface of the ball 31, so that the surface of the ball 31 is subjected to force to push the sliding box 25 downward with the help of the cylinder 30. The downward sliding box 25 will compress the gas spring 28 and pull the connection The sealing plate 26 with the hemispherical body 27 moves down to the inside of the collecting box 4, cancels the obstruction of the sealing plate 26 on the feeding hole 5, restores the flow performance of the feeding hole 5 at the corresponding position, and maintains the flow performance of multiple groups of feeding holes 5 by pressing the sphere 31 with the help of the bottom of the rectangular plate 22, which is beneficial to realize the dynamic adjustment of the adaptability of the feeding holes 5 around the laser head 3, and is beneficial to make the airflow of the cutting station carry the debris into the collecting box 4 when the air pump 12 sucks air to the collecting box 4, reduce the dispersion of the airflow, and shorten the splashing range of the debris. After the rectangular plate 22 cancels the pressing of the sphere 31, the compressed gas spring 28 will recover, thereby pushing the sliding box 25 connected with the sealing plate 26 to move up, and the feeding hole 5 is blocked again by the upwardly moved sealing plate 26, reducing the dispersion of the airflow when the air pump 12 sucks air to the collecting box 4. The hemispherical body 27 on the sealing plate 26 facilitates the debris entering the collecting box 4 to slide down along the surface of the hemispherical body 27 , thereby preventing the debris from accumulating on the sealing plate 26 .

[0035] As an embodiment of the present invention, the centralized absorption component further includes a wetting mechanism, which is used to atomize and wet the debris entering the collection box 4, and the wetting mechanism includes: A water supply tank 32 is fixedly mounted on the bottom of the cutting platform 1; The water storage tank 33 is fixedly mounted on the side wall of the collecting box 4. A plurality of conveying shells 34 corresponding to the plurality of sliding boxes 25 are fixedly connected to the side wall of the water storage tank 33. The ends of all the conveying shells 34 are fixedly penetrated into the interior of the collecting box 4. A solenoid valve 35 is installed on the inner wall of each conveying shell 34. A telescopic tube 36 is fixedly connected to the top of each conveying shell 34. The upper end of each telescopic tube 36 is fixedly connected to the bottom of the adjacent sliding box 25. A plurality of atomizing nozzles 37 are symmetrically installed on both sides of each sliding box 25. Multiple pressure sensors, the number of which is the same as the number of the balls 31, and the multiple pressure sensors are respectively embedded on the surface of the balls 31 to monitor the pressure on the surface of the balls 31, and the multiple pressure sensors are respectively used to control the switches of the multiple solenoid valves 35; The water pump 38 is fixedly installed on the side wall of the water supply tank 32. The water inlet pipe of the water pump 38 is fixedly connected to the inside of the water supply tank 32, and the water outlet pipe of the water pump 38 is fixedly connected to the side wall of the water storage tank 33. When working, the air inlet pipe of the air pump 12 uses the connecting pipe to transport the airflow in the collection box 4 to the outside. Under the guidance of the airflow, the debris is easily sucked onto the conical mesh cover 14, which is not convenient for centralized collection, increases the negative gravity of the conical mesh cover 14, and also affects the air permeability of the conical mesh cover 14. Therefore, by setting the water pump 38, during the cutting process, the water pump 38 is started, and the water pump 38 will transport the water in the water supply tank 32 to the water storage tank 33. When the ball 31 is pressed by the rectangular plate 22 to open the corresponding position of the feed hole 5, the pressure sensor arranged on the surface of the ball 31 senses the pressure, and with the help of the control The control unit controls the electromagnetic valve 35 on the corresponding conveying shell 34 to open, so that the water in the water storage tank 33 enters the sliding box 25 from the opened electromagnetic valve 35 with the help of the telescopic tube 36, and is sprayed out through the atomizing nozzle 37 on the side wall of the sliding box 25. The water mist sprayed by the atomizing nozzle 37 is used to wet the debris entering from the feed hole 5, thereby increasing the weight of the debris after entering the collecting box 4, so that the wetted debris will not fly to the surface of the conical mesh cover 14 with the airflow generated by the air pump 12. The wetted debris falls vertically to the bottom surface of the collecting box 4 under the action of gravity, and a small amount of debris entering from the feed hole 5 above the conical mesh cover 14 is wetted and falls to the surface of the conical mesh cover 14. These small amounts of debris will be cleaned up in time under the scraping of the scraper 16, and will not affect the ventilation performance of the conical mesh cover 14.

[0036] As an embodiment of the present invention, the material identification unit includes a visual identification system, which is installed on the top of the cutting platform 1 and is used to identify the material type of the clamped workpiece to be processed; It should be noted that the visual recognition system can use cameras and image processing software in the prior art to analyze the appearance characteristics of the material, such as color, texture, gloss, etc., to assist in identifying the material type; through automated material recognition and automatic adjustment of the corresponding cutting parameters and negative pressure parameters, the laser cutting equipment of the present application solves the problem that traditional equipment cannot automatically adjust when processing different materials, ensuring the efficiency and accuracy of the cutting process. In addition, it reduces the manual operation that requires frequent adjustment of equipment due to different materials, thereby improving the automation and intelligence level of the production line.

[0037] like Fig.10A control method for a laser cutting device for drawer slides is shown, in which a material information database containing common slides to be processed is established in the control unit, and each type of material information corresponds to a set of cutting parameters and negative pressure parameters. The control method is a control flow of the control unit, and specifically includes the following steps: The control unit transmits the material information identified by the material identification unit to the database, and matches the corresponding cutting parameters and negative pressure parameters; The control unit sends the cutting parameters to the laser head 3 and the plane displacement mechanism to adjust the cutting parameters of the laser head 3 and the plane displacement mechanism to meet the cutting requirements of the corresponding material; The control unit sends the negative pressure parameters to the negative pressure component to adjust the suction force of the air pump 12.

[0038] As an implementation mode of the present invention, the control process of the control unit further includes: The control unit transmits the material information identified by the material identification unit to the database, and generates the first startup information and the second startup information; The control unit sends the first start to the second motor 15 to control the second motor 15 to start, driving the scraper 16 to scrape and clean the surface of the conical mesh cover 14; The control unit sends the second start-up information to the water pump 38 to control the water pump 38 to start and deliver the atomized water flow to the water storage tank 33 .

[0039] As an implementation mode of the present invention, the control process of the control unit further includes: After receiving the pressure information sent by the pressure sensor, the control unit generates corresponding control information; The control unit sends control information to the solenoid valve 35 matched with the pressure sensor to control the solenoid valve 35 to open.

[0040] Working principle of the present invention: with the help of an external manipulator, the workpiece to be made into a drawer slide is placed on two clamping members, and the ends of the workpiece to be processed are clamped by the two clamping members, which is conducive to maintaining the stability of the placement of the workpiece to be processed during the subsequent laser cutting process. The material type of the clamped workpiece to be processed is identified by the material identification unit, and the control unit adjusts the laser head 3 to the corresponding cutting parameters according to the identified material type. The cutting parameters of the laser head 3 include but are not limited to power, focal position, perforation parameters, etc. The plane displacement mechanism is adjusted to the corresponding displacement trajectory and speed. The displacement trajectory set in advance by the plane displacement mechanism can drive the laser head 3 to move in the XY plane, ensuring the flexibility and accuracy of laser cutting, thereby completing the cutting of the corresponding shape of the workpiece to be processed. The set negative pressure component is adjusted to the corresponding negative pressure power according to the material type. The rate forms a negative pressure environment inside the collection box 4, which is conducive to the cutting debris generated at the cutting station entering the collection box 4 with the airflow from the feed hole 5 to be collected, effectively solving the problem of debris splashing and difficulty in centralized collection. The box door set in the collection box 4 is convenient for subsequent staff to open the box door to clean up the debris in the collection box 4 in a unified manner; the material recognition unit can accurately identify the material information of the workpiece to be processed, providing a basis for subsequent parameter adjustment. The control unit automatically adjusts the cutting parameters of the laser head 3 and the plane displacement mechanism according to the identified material information, and adjusts the operating state of the negative pressure component at the same time. This intelligent adjustment ensures that the cutting parameters and the negative pressure intensity are adapted to the material properties, greatly improving the cutting effect and efficiency, and effectively solving the problem that traditional laser cutting equipment needs to manually adjust parameters when facing workpieces to be processed with drawer guides of different materials.
