Description

Technical Field

[0001] This invention relates to the field of CNC cutting technology, specifically to a CNC cutting device. Background Technology

[0002] Thermal insulation boards, also known as insulation panels, are widely used in construction, cold chain logistics, transportation, and other fields. They are typically made of multi-layered composite materials, with significant differences in the physical properties of different layers, such as thermal conductivity, coefficient of thermal expansion, and melting point. With increasingly stringent energy conservation and environmental protection requirements, higher demands are being placed on the processing precision and cutting quality of insulation boards. CNC laser cutting technology, due to its high degree of automation and processing precision, has become the primary method for processing this type of board.

[0003] However, due to the multi-layered composite structure of insulation boards, the intense heat generated during laser cutting creates a heat-affected zone at the cutting edge, altering the material's microstructure and leading to a decline in mechanical properties. For insulation boards, the uneven expansion and contraction of different material layers under heat can easily cause interlayer delamination, edge warping, or deformation. Simultaneously, the high energy density of the laser beam can easily cause burrs on the workpiece edges. If laser parameters are not set properly, raised molten residues may also form on the insulation board edges, severely affecting cutting quality and subsequent assembly accuracy. Although some improvements have been made in existing technologies to address these issues, effective real-time monitoring and feedback adjustment of the heat generated during cutting are still lacking, making it difficult to achieve closed-loop control of cutting quality.

[0004] Therefore, it is necessary to provide a CNC cutting device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a CNC cutting device that can accurately perform temperature adjustment, edge pressing and grinding control, significantly improve the quality and automation of plate cutting, and achieve high-quality, high-precision and environmentally friendly and safe cutting of insulation boards, so as to solve the problems mentioned in the background art.

The edge pressing section is located at the bottom of the detection section. The detection section is used to obtain the pressure change when the edge pressing section contacts the board and when pressing the edge, thereby determining the flatness of the board surface.

[0008] According to the above technical solution, the air inlet hood is connected to a cold source and a blower through a pipeline, and a valve is installed on the pipeline connecting the air inlet hood and the cold source; The air outlet hood is connected to an exhaust fan via a pipe. A filter and a temperature sensor are installed on the pipe connecting the air outlet hood and the exhaust fan. The temperature sensor is located close to the air outlet hood. The pipes connecting the air inlet hood to the cold source and the pipes connecting the air outlet hood to the exhaust fan are all installed through the protective cover.

[0009] According to the above technical solution, the detection unit includes a connecting box, a pressure sensor, several springs, and a sliding block. The connecting box is fixed to the end of an output end of the telescopic rod. The connecting box has a downward-facing opening. The pressure sensor, springs, and sliding block are arranged sequentially from top to bottom inside the connecting box. The pressure sensor is fixedly connected to the connecting box. Several springs are distributed in a dot matrix pattern between the pressure sensor and the sliding block. The two ends of each spring are fixedly connected to the pressure sensor and the sliding block, respectively. The sliding block is slidably connected to the connecting box, and the bottom of the sliding block is located inside the opening of the connecting box.

[0010] According to the above technical solution, the pressing part includes a pressing box and a pressing roller. The pressing box is fixed to the bottom of the sliding block, and the pressing roller is disposed inside the pressing box and rotatably connected to the pressing box.

[0011] According to the above technical solution, the grinding assembly includes a second telescopic rod, a support frame, a second motor, and a grinding disc. The second telescopic rod is fixed on a fixed plate, and the output end of the second telescopic rod passes through the fixed plate and is fixedly connected to the support frame. The second motor is mounted on the support frame, and the grinding disc is fixed to the output end of the second motor.

[0012] According to the above technical solution, a conveying device is provided on the top of the base.

[0013] According to the above technical solution, a three-axis moving seat is fixedly connected to the top of the base. The three-axis moving seat is located outside the conveying device and spans across the top of the conveying device. The cutting mechanism is set on the three-axis moving seat, and the laser cutting head is fixed to the three-axis moving seat through a fixed seat and fasteners.

[0014] According to the above technical solution, an operating table is provided on the side of the base, and a CNC cutting system is provided inside the operating table. The CNC cutting system is provided with an analysis module and a control module. The analysis module is connected to a temperature sensor and a pressure sensor to obtain the hot and cold temperatures recovered when the laser cutting head cuts the plate, thereby indirectly analyzing the degree of heating in the cutting area and whether the cutting state is abnormal. It is also used to obtain the pressure values ​​when the two sets of edge pressing components are in contact with the plate, thereby analyzing the flatness of the plate surface. The control module is electrically connected to the conveying device, the three-axis moving seat, the cutting mechanism, the temperature control mechanism, and the edge pressing mechanism. It is used to control the conveying of the sheet metal, the cutting of the sheet metal, the edge pressing before and after cutting, the grinding after cutting, the provision of protective gas, the cooling, and the removal of cutting debris and fumes, thereby improving the cutting quality of the sheet metal.

By setting up an edge pressing mechanism, while physically flattening the cut edge, the mechanism uses a spring to maintain the preload and a pressure sensor to detect pressure changes in real time. It can simultaneously identify the protrusions and depressions on the surface of the board and the pressure fluctuation curve of the edge pressing roller within a fixed moving distance. It can determine whether the overall flatness of the board is qualified and feed the results back to the control module. The control module can then dynamically adjust the edge pressing state of the telescopic rod or remove the board. This mechanism integrates flattening and detection functions in a single component, achieving online closed-loop control of flatness. By incorporating a temperature control mechanism, protective gas purging, fume extraction, and temperature monitoring can be integrated into the temperature control mechanism. Flatness detection and edge pressing can be integrated into the edge pressing component. An additional grinding component can be added to finely grind the edges that still protrude after flattening. The entire process of laser cutting, temperature control, edge pressing detection, and edge trimming can be completed in a single clamping, which greatly reduces subsequent processing steps and improves production efficiency and cutting quality.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-9 The present invention provides a technical solution: a CNC cutting device, including a base 1, a cutting mechanism 4, a temperature regulating mechanism 5, and an edge pressing mechanism 6. The cutting mechanism 4 is disposed above the base 1, and the temperature regulating mechanism 5 and the edge pressing mechanism 6 are disposed on the cutting mechanism 4. The cutting mechanism 4 is used to perform laser cutting on the plate. The temperature regulating mechanism 5 is used to provide protective gas to the cutting part, cool it, and remove cutting debris and fumes. The edge pressing mechanism 6 is used to selectively press the front and rear parts of the cutting part and to grind the cut edge.

[0019] Specifically, such as Figure 1 As shown, a conveying device 2 is provided on the top of the base 1. The conveying device 2 uses a motor to drive the conveyor belt to rotate in order to achieve the conveying. The conveying device 2 is used to transport the board.

[0020] Specifically, such as Figure 1 As shown, a three-axis moving seat 3 is fixedly connected to the top of the base 1. The three-axis moving seat 3 is located outside the conveying device 2 and spans across the top of the conveying device 2. The cutting mechanism 4 is set on the three-axis moving seat 3. The cutting mechanism 4 adopts a specific driving method according to actual needs. The cutting mechanism 4 is used to drive the temperature regulating mechanism 5 to move back and forth, left and right, and up and down in the space above the conveying device 2, so that the cutting mechanism 4 can cut the plate on the conveying device 2 at any position.

[0021] Specifically, such as Figure 2 As shown, the cutting mechanism 4 includes a fixed base 41 and a laser cutting head 42. The fixed base 41 is fixed to the side of the three-axis moving base 3. The laser cutting head 42 is fixed to the three-axis moving base 3 through the fixed base 41 and using fasteners. The laser cutting head 42 is used to cut the plate.

[0022] Specifically, such as Figures 2-5As shown, the temperature control mechanism 5 includes a connecting seat 51, a motor 52, a protective cover 54, an air inlet cover 55, and an air outlet cover 56. The connecting seat 51 is fixed to the bottom of the fixed seat 41, and the motor 52 is fixed to the top of the connecting seat 51. A guide rail 53 is fixedly connected to the laser cutting head 42. The protective cover 54 is set around the laser cutting head 42, and the top of the protective cover 54 is set inside the guide rail 53 and rotatably connected to the guide rail 53. The output end of the motor 52 passes through the connecting seat 51 and is connected to the outer periphery of the top of the protective cover 54 through gear transmission. The bottom of the protective cover 54 is higher than the bottom of the laser cutting head 42. When the motor 52 is started, it drives the protective cover 54 to rotate forward or backward through gear transmission, thereby adjusting the angle of the protective cover 54 in the circumferential direction. The protective cover 54 is used to form a relatively closed cutting environment without affecting the normal cutting of the laser cutting head 42, preventing cutting debris and fumes from scattering and polluting the processing environment.

[0023] The air inlet hood 55 and the air outlet hood 56 are fixed to the bottom inner wall of the protective cover 54. The air inlet hood 55 is connected to a cold source and a blower through a pipeline. The cold source can be an inert gas source, such as nitrogen. A valve is installed on the pipeline connecting the air inlet hood 55 and the cold source. The valve is used to control the cold source to enter the air inlet hood 55. The blower is used to blow the cold source through the pipeline and the air inlet hood 55 to the cutting position to provide protective gas to the cutting position, cool it, and remove cutting debris and fumes. The exhaust hood 56 is connected to an exhaust fan via a pipe. A filter and a temperature sensor are installed on the pipe connecting the exhaust hood 56 and the exhaust fan. The temperature sensor is located close to the exhaust hood 56. When the exhaust fan is started, it can extract the cold source carrying cutting heat, cutting debris and fumes from inside the protective cover 54. At this time, the temperature sensor obtains the temperature of the extracted gas and indirectly judges the degree of heating or cutting status of the cutting area. At the same time, the filter removes cutting debris and fumes to prevent debris from flying during cutting and polluting the processing environment. The pipes connecting the air inlet hood 55 to the cold source and the pipes connecting the air outlet hood 56 to the exhaust fan are both installed through the protective cover 54.

[0024] Specifically, such as Figures 3-9 As shown, the edge pressing mechanism 6 includes two sets of fixed plates 61, two sets of edge pressing components, and one set of grinding components. The two sets of fixed plates 61 are located above the air inlet hood 55 and the air outlet hood 56, respectively. The two sets of edge pressing components are respectively set on the two sets of fixed plates 61. The grinding components are set on the fixed plate 61 above the air outlet hood 56. The fixed plates 61 are used to provide support for the edge pressing components and the grinding components, and at the same time, they separate the upper and lower parts of the fixed plates 61 to prevent cutting debris and smoke from flying to the upper part of the fixed plates 61. The edge pressing components are used to detect the flatness of the cut parts before and after cutting, and to flatten the cut parts to prevent the cut edges from curling. The grinding components are used to grind the protruding cut edges that still curl after flattening, reducing subsequent processing steps and simplifying the processing steps.

[0025] It should be noted that the fixing plate 61 may be provided with an arc-shaped splicing structure that wraps around the laser cutting head 42, thereby completely separating the upper and lower parts of the fixing plate 61, further preventing cutting debris and fumes from scattering onto the upper part of the fixing plate 61 and creating a cleaning blind spot.

[0026] Furthermore, such as Figures 3-8 As shown, the edge pressing assembly includes two sets of telescopic rods 62, a detection part, and an edge pressing part. The telescopic rods 62 are fixed on the fixed plate 61. The output end of the telescopic rods 62 passes through the fixed plate 61 and is fixedly connected to the detection part. The edge pressing part is located at the bottom of the detection part. The detection part is used to obtain the pressure change when the edge pressing part contacts the board and when pressing the edge, thereby determining the flatness of the board surface.

[0027] Furthermore, such as Figure 6 and Figure 8 As shown, the detection unit includes a connecting box 63, a pressure sensor 64, several springs 65, and a sliding block 66. The connecting box 63 is fixed to the end of the output end of the telescopic rod 62. The connecting box 63 has a downward-facing opening. The pressure sensor 64, springs 65, and sliding block 66 are arranged sequentially from top to bottom inside the connecting box 63. The pressure sensor 64 is fixedly connected to the connecting box 63. Several springs 65 are distributed in a dot matrix between the pressure sensor 64 and the sliding block 66. The two ends of the springs 65 are fixedly connected to the pressure sensor 64 and the sliding block 66, respectively. The sliding block 66 is slidably connected to the connecting box 63, and the bottom of the sliding block 66 is located inside the opening of the connecting box 63.

[0028] Furthermore, such as Figure 6 and Figure 8 As shown, the pressing part includes a pressing box 67 and a pressing roller 68. The pressing box 67 is fixed to the bottom of the sliding block 66. The pressing roller 68 is disposed inside the pressing box 67 and is rotatably connected to the pressing box 67. The pressing roller 68 is used to contact the surface of the board and uses the friction force when in contact with the board to realize its own rotation and realize follow-up rolling along the cutting direction.

[0029] In actual operation, when the pressure roller 68 contacts the surface of the board and encounters a protrusion, it will move upward relative to the telescopic rod 62 and transmit the force to the sliding block 66 through the pressure box 67. This causes the sliding block 66 to be squeezed towards the telescopic rod 62, and simultaneously causes the sliding block 66 to move upward relative to the connecting box 63, compressing the spring 65 and thus squeezing the pressure sensor 64. This increases the pressure value detected by the pressure sensor 64, thereby enabling the determination that the board is in a protruding state at that position. When the pressure roller 68 moves to a flat area, the upward pressure on the sliding block 66 decreases. Under the elastic force of the spring 65, the sliding block 66 moves downward to reset. At this time, the pressure value detected by the pressure sensor 64 decreases and returns to the set range. This set range is set by the operator according to actual needs.

[0030] It should be noted that, in order to enable the detection unit to detect recessed areas, the length of the pressure roller 68 can be adjusted according to actual needs, or a contact ring can be fitted at the center of the pressure roller 68. The inner diameter of the contact ring matches the outer diameter of the pressure roller 68, that is, the outer diameter of the contact ring is larger than the outer diameter of the pressure roller 68. This allows the contact ring to replace the pressure roller 68 in contact with the board surface, reducing the contact length between the pressure roller 68 and the board in the axial direction, thereby improving detection accuracy. At the same time, the minimum value of the pressure range set by the operator is not zero, thus keeping the sliding block 66 continuously squeezed towards the telescopic rod 62. This allows the pressure sensor 64 to continuously detect non-zero pressure values. When the pressure sensor 64 detects a pressure value lower than the minimum value of the set pressure range or a pressure value of zero, it can quickly determine that the board is recessed at that location, thereby achieving the effect of detecting the flatness of the board surface. In addition, this method can also be used to obtain the overall flatness of the board surface based on the fluctuation of the pressure data detected by the pressure sensor 64 within a certain moving distance of the pressure roller 68. Remove boards that do not meet the flatness standard in a timely manner to avoid cutting boards with poor flatness, which would reduce the pass rate of cutting.

[0031] Furthermore, such as Figures 3-8 As shown, the grinding assembly includes a telescopic rod 69, a support frame 610, a motor 611, and a grinding disc 612. The telescopic rod 69 is fixed on the fixed plate 61, and the output end of the telescopic rod 69 passes through the fixed plate 61 and is fixedly connected to the support frame 610. The motor 611 is mounted on the support frame 610, and the grinding disc 612 is fixed to the output end of the motor 611. When the motor 611 is started, it drives the grinding disc 612 to rotate, thereby enabling the grinding disc 612 to grind the edges that are flattened after cutting but still protrude.

[0032] Specifically, such as Figure 1 As shown, an operating table 7 is provided on the side of the base 1. The operating table 7 is used by the operator to set relevant parameters for cutting the sheet metal, including but not limited to the speed at which the conveying device 2 conveys the sheet metal, the movement path of the three-axis moving seat 3 driving the cutting mechanism 4, the cutting power of the laser cutting head 42, and the edge pressing status of the two sets of edge pressing components.

[0033] The operating table 7 is equipped with a CNC cutting system. The CNC cutting system is equipped with an analysis module and a control module. The analysis module is connected to the temperature sensor and pressure sensor 64 to obtain the hot and cold temperatures recovered when the laser cutting head 42 cuts the plate. This allows for indirect analysis of the degree of heating in the cutting area and whether the cutting state is abnormal. It is also used to obtain the pressure values ​​when the two sets of edge pressing components are in contact with the plate, thereby analyzing the flatness of the plate surface. The control module is electrically connected to the conveying device 2, the three-axis moving base 3, the laser cutting head 42, the first motor 52, the exhaust fan, the blower, the first telescopic rod 62, the second telescopic rod 69, and the second motor 611. It is used to control the conveying of the sheet metal, the cutting of the sheet metal, the pressing of the edges before and after cutting, the grinding after cutting, the provision of protective gas, the cooling, and the removal of cutting debris and fumes, thereby improving the cutting quality of the sheet metal.

[0034] Cutting methods of CNC cutting devices: Step 1: Sheet Material Conveying and Positioning: Start the conveyor device 2, and the motor-driven conveyor belt will transport the sheet material to be cut to the processing station. At the same time, the control module in the operating table 7 controls the three-axis moving seat 3 to drive the cutting mechanism 4 to move back and forth, left and right, and up and down above the conveyor device 2 according to preset parameters, so as to accurately move the laser cutting head 42 to the starting position of the sheet material to be cut.

[0035] Step 2, Laser Cutting and Temperature Control Protection: The control module starts the laser cutting head 42 to cut the sheet material. During the cutting process, the temperature control mechanism 5 starts simultaneously. Air supply and cooling: The control module turns on the blower and the cold source valve. The cold source blows towards the cutting position through the air inlet hood 55, providing protective air and cooling the cutting area, while blowing away cutting debris and smoke.

[0036] Exhaust and Temperature Monitoring: The control module activates the exhaust fan to extract the mixture of gas carrying heat, debris, and fumes through the exhaust hood 56. A temperature sensor located near the exhaust hood 56 acquires the temperature of the extracted gas in real time and transmits the temperature signal to the analysis module. Based on this, the analysis module indirectly determines the real-time heating level of the cutting area and whether the cutting status is abnormal. If the temperature is abnormal, the control module can adjust the cutting power or gas flow rate of the laser cutting head 42 in a timely manner.

[0037] Step 3: Dynamic Inspection of Edge Pressing and Sheet Flatness: During the cutting process, the control module controls the movement of two sets of edge pressing components to inspect the edge pressing and flatness of the areas before and after the cut. Performing the edge pressing action: The control module drives the telescopic rod 62 to extend, pushing the edge pressing part downward, so that the edge pressing roller 68 is in close contact with the surface of the board, achieving physical flattening and preventing the edge from warping. During this process, since the minimum value of the pressure range set by the system is not zero, and the pressure detected by the pressure sensor 64 must be kept within the set range, the edge pressing part always maintains pre-tight force.

[0038] Pressure Sensing and Data Acquisition: When the pressure roller 68 rolls to the protruding position of the sheet metal, the pressure roller 68 experiences upward resistance, which pushes the sliding block 66 upward relative to the connecting box 63 through the pressure box 67, compressing the spring 65 and squeezing the pressure sensor 64. At this time, the real-time value detected by the pressure sensor 64 increases and exceeds the upper limit of the set range. Based on this, the analysis module determines that the position is a protruding state.

[0039] When the pressure roller 68 rolls to the recessed position of the sheet metal, the upward pressure on the sliding block 66 decreases, the spring 65 pushes the sliding block 66 to return to its original position downwards, and the value detected by the pressure sensor 64 decreases. Since the minimum value of the set range is not zero, once the detected value falls below the lower limit of the set range or drops sharply to zero, the analysis module quickly determines that the position is in a recessed state.

[0040] Flatness Analysis: The analysis module continuously records the pressure fluctuation curve collected by the pressure sensor 64 within a fixed distance that the pressure roller 68 moves along the cutting direction. If the maximum fluctuation amplitude of the pressure data within this distance exceeds a preset threshold (set by the operator according to actual needs), the analysis module determines that the overall flatness of the board is unqualified and sends the determination result to the control module. The control module then executes board rejection or dynamically adjusts the pressure state of the telescopic rod 62 to achieve precise closed-loop control of flatness.

[0041] Step 4: Linkage Control between the Analysis Module and the Control Module: The analysis module transmits the processed flatness and temperature data to the control module in real time. The control module then executes the following selective linkage strategy: Flatness control: If the analysis module determines that the overall flatness of the board surface does not meet the standard, the control module sends a rejection signal, stops subsequent processing and marks the board. The conveyor 2 then conveys the board from the processing station to the unloading area, where workers or robots remove the board, thereby avoiding a decrease in the cutting qualification rate.

[0042] Edge pressing state adjustment: The control module dynamically adjusts the extension amount of the telescopic rod 62 according to the detected protrusion and depression pressure values, that is, controls the extension pressure of the edge pressing roller 68 when it contacts the board, ensuring that the edge pressing roller 68 can effectively flatten the board without damaging the surface of the board due to excessive pressure.

[0043] Cutting coordination: Combining the heat data fed back by the temperature sensor, the control module comprehensively adjusts the conveying speed of the conveying device 2 and the power of the laser cutting head 42 to achieve dynamic matching between heat input and edge flatness.

[0044] Step 5: Grinding the protruding edges after cutting: After the cutting and pressing processes are completed, if there are still protruding burrs or warping on the cut edges, the control module activates the grinding component. Telescopic rod 2 69 extends, pushing the support frame 610 and motor 2 611 to the designated position. Motor 2 611 drives the grinding disc 612 to rotate at high speed, finely grinding the edges that are still protruding after being flattened, completing the final processing.

[0045] Through the above steps, the device utilizes real-time data feedback from pressure sensor 64 and temperature sensor. After analysis by the analysis module, the control module precisely executes temperature adjustment, edge pressing, and grinding control, significantly improving the quality and automation of board cutting and achieving high-quality, high-precision, and environmentally friendly and safe cutting of insulation boards.
