Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, and more specifically, to a laser cutting device and method for hardware accessories. Background Technology

[0002] Cutting is a common process in the processing of hardware parts. Since most hardware parts are made of metal, laser cutting equipment is often used for this type of processing due to its high precision and efficiency. The worktable of the laser cutting machine, as an important part of the cutting process, is often designed with multiple horizontal support plates with gaps. This is because during laser cutting, the high-energy laser beam acts on the metal material, causing it to melt or vaporize rapidly, thus generating a large amount of slag and waste. If this slag and waste accumulate on the worktable, it will not only affect the cleanliness of the cutting area, but may also interfere with the transmission of the laser beam and reduce the cutting accuracy. The gaps between the multiple support plates allow the slag and waste to pass smoothly through the worktable, avoiding accumulation and thus keeping the cutting area clean.

[0003] The structure of the horizontal support plate also provides stable support for the metal material. During the cutting process, the metal material needs to remain flat and stable to ensure the accuracy and quality of the cutting. The gap between the support plates reduces the contact area between the worktable and the material, while also reducing heat conduction, which helps to control the heat-affected zone and reduce material deformation and thermal stress.

[0004] However, during the cutting of metal parts, laser cutting machines also generate high-temperature molten metal slag and spatter. This slag and spatter easily adhere to the surface of the support plate during cutting, and after cooling, they stick to the support plate. Over time, the surface of the support plate becomes uneven, leading to uneven workpiece placement and errors in cutting height. Simultaneously, the metal slag adhering to the support plate surface reduces the gap between the two support plates, affecting material feeding and air circulation. To solve these problems, manual cleaning of the metal slag adhering to the support plate surface is typically done periodically. This is because the molten metal slag undergoes metallurgical bonding with the support plate surface under high temperature, forming a hardened layer with high adhesion strength after cooling. This physical bonding characteristic makes traditional mechanical cleaning methods inefficient, often requiring operators to repeatedly scrape with tools such as scrapers and wire brushes. However, the worktable structure composed of multiple beams inherently has spatial limitations, with small gaps between adjacent support plates, objectively restricting the manual operating space. This makes manual operation difficult, resulting in unsatisfactory cleaning effects and easily creating cleaning dead zones in corners. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention aims to provide a laser cutting device and method for hardware accessories. This device can generate high-frequency vibration by driving a scraper with an ultrasonic transducer, which can more effectively remove metal slag adhering to the surface of the support plate. The high-frequency vibration significantly improves the cleaning efficiency and ensures the improvement of the cleaning quality. In addition, this application can also implement differentiated cleaning strategies for each support plate or even different areas on the support plate. This differentiated cleaning scheme not only ensures the optimization of the overall cleaning effect, but also effectively controls the resource consumption during the cleaning process.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] In a first aspect, a laser cutting device for hardware accessories includes a base, on which multiple sets of equidistantly arranged support plates are mounted. A crossbeam is slidably arranged inside the base, and the crossbeam is located below the support plates. A driving assembly is also installed inside the base, which drives the crossbeam to move left and right inside the base. Multiple cleaning components are arranged above the crossbeam, and the number of cleaning components corresponds to the number of support plates. Each cleaning component includes a scraper, which is sleeved on the support plate. An ultrasonic transducer is fixedly connected to the lower end of the scraper, and a slider is fixedly installed at the lower end of the ultrasonic transducer. The slider is mounted on the crossbeam. A control module is installed inside the crossbeam, and the control module is used to control the corresponding ultrasonic transducer to vibrate at high frequency.

[0008] Furthermore, the cleaning assembly also includes a squeezing block, which is installed at the left and right ends of the slider. A groove is provided on the upper surface of the crossbeam corresponding to the position of the slider. The slider is slidably disposed in the groove. A pressure sensor is installed on the inner wall of the groove opposite the position of the squeezing block.

[0009] Furthermore, the cleaning assembly also includes a high-frequency coil, which is disposed on the left and right sides of the scraper and sleeved on the support plate. The lower end of the high-frequency coil is fixedly connected to the crossbeam. A heat-conducting column is embedded inside the scraper. One end of the heat-conducting column contacts the support plate. A temperature sensor is embedded on the end of the heat-conducting column away from the support plate. The support plate is made of magnetic material.

[0010] Furthermore, the drive assembly includes a motor, which is installed inside the base. A lead screw is fixedly installed on the output shaft of the motor. The end of the lead screw away from the motor passes through the crossbeam and extends to the outside. The lead screw is threadedly connected to the crossbeam. An optical shaft is movably arranged inside the end of the crossbeam away from the lead screw. Both ends of the optical shaft pass through the crossbeam and are fixedly connected to the inside of the base.

[0011] Secondly, a laser cutting method for the aforementioned hardware accessories includes the following steps:

[0012] Step 1: The drive component controls the crossbeam to move left and right at a set speed, which in turn drives the scraper to move along the surface of the support plate and clean the metal slag adhering to the surface of the support plate.

[0013] Step 2: During the cleaning process, the corresponding ultrasonic transducer is activated by the control module to generate a preset vibration frequency. The ultrasonic transducer drives the scraper to generate high-frequency vibration, and the high-frequency vibrating scraper cleans the metal slag adhering to the surface of the support plate.

[0014] Step 3: Activate the corresponding high-frequency coil according to the scraper's movement direction. As the scraper moves forward, the high-frequency coil in front of it generates a high-frequency current, causing the temperature of the corresponding part of the support plate to rise. This heats the metal slag in the corresponding area through the support plate, reducing the bonding strength between the support plate and the metal slag.

[0015] Further, in step 21, the scraper compresses the metal slag during the cleaning process, and the metal slag exerts a counter-force on the scraper, causing the slider to slide within the groove. The compression block on the slider will compress the corresponding pressure sensor, and the pressure sensor monitors the pressure value on the scraper in real time. At pressure value Pressure exceeding the pre-set threshold At that time, the pressure value With pressure threshold The difference is calculated and used as feedback to adjust the frequency of the ultrasonic transducer.

[0016] Step 22, the specific method for adjusting the ultrasonic transducer frequency based on the difference is as follows: ,in The frequency after the ultrasonic transducer has been adjusted; The initial vibration frequency of the ultrasonic transducer; This is the pressure regulation coefficient. This represents the highest frequency threshold that the ultrasonic transducer has been adjusted to.

[0017] Further, in step 31, the initial heating power of the high-frequency coil is preset. At that time, the high-frequency coil is controlled to heat the support plate with the initial heating power;

[0018] If it appears ,and At that time, according to the preset temperature of the support plate With real-time temperature The difference is used as a feedback signal to adjust the heating power of the high-frequency coil;

[0019] Step 32, the specific method for adjusting the heating power of the high-frequency coil is as follows: ,in This represents the initial heating power of the high-frequency coil; This refers to the heating power adjusted by the high-frequency coil. This is expressed as a temperature regulation coefficient; This represents the maximum heating power that the high-frequency coil can deliver.

[0020] Further, in step 221, based on the working time of the laser cutting machine... To adjust the pressure regulation coefficient The specific adjustment method for the value is as follows: ,in This is the initial value of the pressure regulation coefficient; This is the factor that influences the frequency adjustment coefficient on the working duration.

[0021] Further, in step 321, based on the working time of the laser cutting machine... To adjust the temperature regulation coefficient The specific adjustment method for the value is as follows: ,in The initial value of the temperature regulation coefficient. This represents the weight of the effect of working hours on the temperature regulation coefficient.

[0022] Thirdly, one or more processors, including:

[0023] A storage device for storing one or more programs that, when executed by one or more processors, cause the one or more processors to implement the method.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] (1) This solution uses an ultrasonic transducer to drive a scraper to generate high-frequency vibration, which can more effectively remove metal slag adhering to the surface of the support plate. Compared with the traditional manual cleaning method, high-frequency vibration significantly improves the cleaning efficiency and ensures the improvement of cleaning quality, making the surface of the support plate cleaner and flatter. It can also implement differentiated cleaning strategies for each support plate or even different areas on the support plate. For the central area where workpieces are frequently placed and where metal slag is heavily adhered, stronger cleaning measures can be taken to ensure thorough cleaning; while for the edge areas or areas with lighter adhesion, a relatively mild cleaning method can be used to save costs. This differentiated cleaning solution not only ensures the optimization of the overall cleaning effect, but also effectively controls the resource consumption during the cleaning process.

[0026] (2) This solution has an intelligent adjustment mechanism that can dynamically adjust the vibration frequency of the ultrasonic transducer and the heating power of the high-frequency coil according to the actual pressure the scraper receives during the cleaning process and the real-time temperature of the support plate. This feedback adjustment mechanism enables the cleaning process to flexibly cope with metal slag with different adhesion strengths, while effectively controlling energy consumption and improving the adaptability and energy saving of the cleaning process.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 4A laser cutting device for hardware accessories includes a base 1, on which multiple sets of equidistantly arranged support plates 2 are installed. A crossbeam 3 is slidably arranged inside the base 1 and is located below the support plates 2. A drive assembly is also installed inside the base 1 to drive the crossbeam 3 to move left and right inside the base 1. Multiple cleaning assemblies are arranged above the crossbeam 3, and the number of cleaning assemblies corresponds to the number of support plates 2. The cleaning assembly includes a scraper 10, which is sleeved on the support plate 2. An ultrasonic transducer 9 is fixedly connected to the lower end of the scraper 10. A slider 8 is fixedly installed at the lower end of the ultrasonic transducer 9 and is mounted on the crossbeam 3. A control module is installed inside the crossbeam 3 to control the corresponding ultrasonic transducer 9 to vibrate at high frequency.

[0036] The cleaning assembly also includes a squeezing block 12, which is installed at the left and right ends of the slider 8. A groove 7 is provided on the upper surface of the crossbeam 3 at the position corresponding to the slider 8. The slider 8 is slidably disposed in the groove 7. A pressure sensor 11 is installed on the inner wall of the groove 7 at the position opposite to the squeezing block 12.

[0037] The cleaning assembly also includes a high-frequency coil 13, which is disposed on the left and right sides of the scraper 10 and is sleeved on the support plate 2. The lower end of the high-frequency coil 13 is fixedly connected to the crossbeam 3. A heat-conducting column 15 is embedded inside the scraper 10. One end of the heat-conducting column 15 is in contact with the support plate 2. A temperature sensor 14 is embedded on the end of the heat-conducting column 15 away from the support plate 2. The support plate 2 is made of magnetic material.

[0038] The drive assembly includes a motor 6, which is installed inside the base 1. A lead screw 5 is fixedly installed on the output shaft of the motor 6. The end of the lead screw 5 away from the motor 6 passes through the crossbeam 3 and extends to the outside. The lead screw 5 is threadedly connected to the crossbeam 3. An optical shaft 4 is movably installed inside the end of the crossbeam 3 away from the lead screw 5. Both ends of the optical shaft 4 pass through the crossbeam 3 and are fixedly connected to the inside of the base 1.

[0039] In this embodiment, after the laser cutting equipment has finished processing the hardware parts, if the surface of the support plate 2 needs to be cleaned, the motor 6 can be turned on. The motor 6 drives the lead screw 5 to rotate in both directions. The rotation of the lead screw 5 can drive the crossbeam 3 to move left and right within the base 1. When the crossbeam 3 moves, it will drive the scraper 10 to move along the support plate 2. During the movement of the scraper 10, it will clean the metal slag adhering to the surface of the support plate 2. During the movement of the scraper 10, the ultrasonic transducer 9 is turned on. The ultrasonic transducer 9 drives the scraper 10 to generate high-frequency vibration. The high-frequency vibration of the scraper 10 makes it easier to clean the metal slag adhering to the surface of the support plate 2, thereby improving the cleaning efficiency and cleaning effect. If the scraper 10 moves to the right, the high-frequency coil 13 on the right side of the scraper 10 is activated; if the scraper 10 moves to the left, the high-frequency coil 13 on the left side of the scraper 10 is activated. In this way, as the scraper 10 moves forward, the high-frequency coil 13 can preheat the support plate 2 corresponding to the high-frequency coil 13 locally. The temperature of the support plate 2 is also transferred to the metal slag. By heating both, the bonding strength between the support plate 2 and the metal slag is reduced. This makes it easier for the scraper 10 to clean the metal slag when it moves to the heated area, further improving the efficiency and cleaning effect of cleaning the surface of the support plate 2.

[0040] The present invention also provides a laser cutting method for the above-mentioned hardware accessories, comprising the following steps:

[0041] Step 1: The crossbeam 3 is controlled by the drive component to move left and right at a set speed, which will drive the scraper 10 to move along the surface of the support plate 2 and clean the metal slag adhering to the surface of the support plate 2.

[0042] Step 2: During the cleaning process, the corresponding ultrasonic transducer 9 is activated by the control module through the scraper 10, so that the ultrasonic transducer 9 generates a preset vibration frequency. The ultrasonic transducer 9 drives the scraper 10 to generate high-frequency vibration, and the high-frequency vibrating scraper 10 cleans the metal slag adhering to the surface of the support plate 2.

[0043] Step 3: Activate the corresponding high-frequency coil 13 according to the moving direction of the scraper 10. When the scraper 10 moves forward, the high-frequency coil 13 in front of it will generate a high-frequency current, which will raise the temperature of the corresponding part of the support plate 2. The support plate 2 will heat the metal slag in the corresponding area, thereby reducing the bonding strength between the support plate 2 and the metal slag.

[0044] Step 2 also includes:

[0045] Step 21: During the cleaning process, the scraper 10 squeezes the metal slag, and the metal slag gives the scraper 10 a counter-force, causing the slider 8 to slide within the groove 7. The squeezing block 12 on the slider 8 will squeeze the corresponding pressure sensor 11, and the pressure sensor 11 will monitor the pressure value of the scraper 10 in real time. At pressure value Pressure exceeding the pre-set threshold At that time, the pressure value With pressure threshold Perform difference calculation, and use the difference as feedback to adjust the frequency generated by the ultrasonic transducer 9;

[0046] Step 22, the specific method for adjusting the frequency of the ultrasonic transducer 9 based on the difference is as follows: ,in The frequency of the ultrasonic transducer 9 after adjustment; The initial vibration frequency of the ultrasonic transducer 9; This is the pressure regulation coefficient. This represents the highest frequency threshold that the ultrasonic transducer 9 has been adjusted to.

[0047] In this embodiment, when the scraper 10 moves to the right along the support plate 2, the pressing block 12 on the left side of the slider 8 presses the pressure sensor 11 on the left side of the inner wall of the chute 7; when the scraper 10 moves to the left along the support plate 2, the pressing block 12 on the right side of the slider 8 presses the pressure sensor 11 on the right side of the inner wall of the chute 7. That is, regardless of whether the scraper 10 moves left or right along the support plate 2, the pressing force of the scraper 10 on the metal slag can be detected by different pressure sensors 11. When the scraper 10 moves, the ultrasonic transducer 9 vibrates at the initially set vibration frequency, that is... The condition that is satisfied at this time is Under these conditions, it is evident that scraper 10 can more easily remove metal slag from support plate 2. When... At this point, the scraper 10 applies significant pressure to the metal slag, indicating that it is difficult for the scraper 10 to remove the metal slag from the support plate 2. In this situation, the control module will adjust the frequency of the ultrasonic transducer 9. The specific adjustment method is as follows: The pressure value is monitored in real time by pressure sensor 11. and the preset pressure value By comparing the two and using the difference as a feedback signal, the frequency of the ultrasonic transducer 9 can be dynamically adjusted to enhance the high-frequency crushing effect of the scraper 10 on metal slag. If, after crushing the metal slag at that location, further damage occurs... At that time, the frequency on the ultrasonic transducer 9 will return to The state, that is, when the pressure decreases, switches to a low-frequency mode to reduce energy consumption. Because each support plate 2 is equipped with a cleaning component, different cleaning schemes can be implemented for different support plates 2. For example, the part in the center of the workbench often places workpieces, and metal slag easily sticks to it during cutting, while the support plates 2 at the edge of the workbench only need to occupy the entire workbench when cutting large metal workpieces, and metal slag only sticks to the edge support plates 2 during cutting. In this way, this application can implement different cleaning schemes for each support plate 2. In addition, this application can also apply different cleaning schemes to different parts of the support plate 2 based on the different strengths of the local metal slag adhesion on each support plate 2. This design ensures the cleaning effect on the support plate 2 while minimizing the energy consumption during cleaning. If during cleaning, When the maximum frequency of the ultrasonic transducer 9 has been reached, the control module will control the ultrasonic transducer 9 to output its maximum power to ensure that the scraper 10 crushes the metal slag as much as possible.

[0048] In a preferred embodiment of the present invention, step S3 further includes the following steps:

[0049] Step 31, preset the initial heating power of the high-frequency coil 13. At that time, the high-frequency coil 13 is controlled to heat the support plate 2 with the initial heating power;

[0050] If it appears ,and At that time, according to the preset temperature of support plate 2 With real-time temperature The difference is used as a feedback signal to adjust the heating power of the high-frequency coil 13;

[0051] Step 32, the specific method for adjusting the heating power of the high-frequency coil 13 is as follows: ,in This is the initial heating power of the high-frequency coil 13; The heating power of the high-frequency coil 13 was adjusted. This is expressed as a temperature regulation coefficient; This represents the maximum heating power that the high-frequency coil 13 can perform.

[0052] In this embodiment, when the scraper 10 is crushing metal slag, it exhibits... In this situation, the high-frequency coil 13 is implemented. The power is used to heat the support plate 2, so that the high-frequency coil 13 can preheat the support plate 2 corresponding to the high-frequency coil 13 locally. The temperature of the support plate 2 will also be transferred to the metal slag, thereby reducing the bonding strength between the support plate 2 and the metal slag. This makes it easier for the scraper 10 to crush and clean the metal slag when it moves to the heated area. If... ,and At this point, it indicates that even with the ultrasonic transducer 9 outputting its maximum vibration frequency, the scraper 10 still struggles to break up and clean the metal slag. Therefore, based on the preset temperature of the support plate 2... That is, the maximum temperature that the support plate 2 can be heated to, and the preset temperature. Temperature detected by temperature sensor 14 The two are compared, and the difference between them is used as a feedback signal to adjust the heating power of the high-frequency coil 13 on the support plate 2. The specific adjustment method is as follows: This design allows for the application of different heating powers to different support plates 2, and also to different localized areas of metal slag on the support plates 2. This design minimizes energy consumption during cleaning while ensuring the scraper 10 effectively removes the metal slag. When the maximum heating power of the high-frequency coil 13 is reached, the maximum heating power of the high-frequency coil 13 is output to ensure the scraper 10 cleans the metal slag. It should be noted that one end of the heat-conducting column 15 is in contact with the support plate 2, and the temperature sensor 14 is embedded in the heat-conducting column 15. Detecting the temperature of the heat-conducting column 15 through the temperature sensor 14 is equivalent to detecting the temperature of the support plate 2. The heat-conducting column 15 can be made of alloy materials such as copper and aluminum to ensure its thermal conductivity.

[0053] In a preferred embodiment of the present invention, step S23 further includes:

[0054] Step 231, based on the working time of the laser cutting machine To adjust the pressure regulation coefficient The specific adjustment method for the value is as follows: ,in This is the initial value of the pressure regulation coefficient; This is the factor that influences the frequency adjustment coefficient on the working duration.

[0055] In this embodiment, the longer the laser cutting equipment operates, the more metal slag adheres to the support plate 2, making it more difficult to clean. Therefore, the pressure adjustment coefficient is dynamically adjusted based on the equipment's operating time as a feedback signal. The specific adjustment method is as follows: This design can alter the sensitivity of the ultrasonic transducer 9's frequency adjustment. For example, if the equipment operates for a short time, there will be relatively less metal slag adhering to the support plate 2, thus reducing the pressure adjustment coefficient. The adjustment can be made relatively sluggish to avoid over-response. For example, if the equipment operates for a long time, a relatively large amount of metal slag will adhere to the support plate 2, thus adjusting the pressure adjustment coefficient. It can be adjusted to be relatively sensitive, which can avoid the problem of incomplete cleaning due to adjustment lag. In addition, the initial value of the pressure adjustment coefficient. It can be customized according to the materials that are frequently processed, such as when cutting ordinary carbon steel, aluminum alloys, etc. It can be set to 0.8 - 1.2 because the residue hardness and adhesion of these materials are moderate, and a low initial coefficient can meet basic cleaning needs, avoiding excessive frequency adjustment. When cutting stainless steel, titanium alloys, and other materials with high hardness, to ensure rapid and effective residue removal, It can be increased to 1.5 - 2.0, allowing the ultrasonic frequency to respond more quickly to pressure changes.

[0056] In a preferred embodiment of the present invention, step S32 further includes:

[0057] Step 321, based on the working time of the laser cutting machine To adjust the temperature regulation coefficient The specific adjustment method for the value is as follows: ,in The initial value of the temperature regulation coefficient. This represents the weight of the effect of working hours on the temperature regulation coefficient.

[0058] In this embodiment, the longer the laser cutting equipment operates, the more metal slag adheres to the support plate 2, making it more difficult to clean. Therefore, the operating time of the equipment serves as a feedback signal to dynamically adjust the temperature regulation coefficient. The specific adjustment method is as follows: The purpose of this is to ensure that the intensity of heating-assisted cleaning is appropriately increased, guaranteeing good cleaning results for different working durations, avoiding excessive heating that wastes energy and damages equipment, and rationally controlling energy consumption while ensuring cleaning effectiveness. Additionally, The initial value of the temperature regulation coefficient can be defined based on the external temperature conditions. For example, when the ambient temperature is between 20℃ and 25℃, or when cutting materials such as copper or aluminum, which have relatively low melting points, It can be set to 0.3-0.5. A lower initial coefficient can gently heat the support plate 2 in the initial stage, aiding in the removal of residue. For example, when the ambient temperature is below 10℃, or when cutting high-melting-point metals such as tungsten steel, to accelerate the heating rate of the support plate 2, The temperature should be increased to 0.6-0.8 to ensure that the temperature can effectively reduce the adhesion of residues.

All implementations in the above method embodiments are applicable to this embodiment and can achieve the same technical effects.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
