Description

Technical Field

[0001] This utility model relates to the field of vacuum insulation panel processing technology, and in particular to a laser cutting device for vacuum insulation panels. Background Technology

[0002] With the increasing demand for energy conservation and environmental protection, vacuum insulation panels (VIPs) are widely used as high-efficiency insulation materials in home appliances, construction, and cold chain logistics. The cutting of irregularly shaped vacuum insulation panels requires smooth cuts, no burrs, and a small heat-affected zone to avoid damaging the vacuum structure and insulation performance within the panel. Traditional mechanical cutting easily produces mechanical stress deformation and burrs, while flame cutting results in a large heat-affected zone, neither of which can meet the high-precision requirements. Therefore, laser cutting has been developed. Although laser cutting has the advantages of being non-contact and having a small heat-affected zone, existing equipment suffers from poor positioning accuracy when cutting irregularly shaped panels, making it difficult to accurately position and cut them.

[0015] The technical solution adopted in this utility model can achieve the following beneficial effects:

[0016] 1. This utility model provides a vacuum insulation panel laser cutting equipment, comprising a frame, a laser cutting system, a mechanical transmission system, and a positioning device. A worktable is embedded within the frame. The mechanical transmission system is mounted on the frame, and the laser cutting system is slidably mounted on the mechanical transmission system. The mechanical transmission system includes an X-axis motion component, a Y-axis motion component, and a Z-axis motion component. The positioning device includes at least two positioning components, which are evenly distributed along the circumference of the frame. This equipment integrates a three-axis linkage mechanical transmission system, allowing the laser cutting system to move along the three axes with the mechanical transmission system. The cutting position is flexible and adjustable, and the movement is stable, enabling it to adapt well to the cutting of various irregularly shaped vacuum insulation panels and achieve zero dead angle cutting. Simultaneously, by evenly distributing the positioning components along the circumference of the frame, a multi-angle collaborative positioning reference can be formed, improving positioning accuracy, effectively eliminating the rotational degree-of-freedom error present in traditional single-point positioning, significantly improving the robustness of three-dimensional spatial positioning of irregularly shaped workpieces, and ensuring precise matching between the laser cutting path and the workpiece contour.

[0017] 2. The positioning device integrates a vision recognition module, and the positioning component is an infrared through-beam sensor. The vision recognition module, positioning component, and mechanical transmission system are electrically connected to the control system. The composite positioning method integrating the vision recognition module and the infrared through-beam sensor, combined with the data fusion algorithm of the control system, can achieve global scanning of workpiece contour features and precise edge positioning. Compared with the single sensing mode, the positioning efficiency is significantly improved. At the same time, the mechanical transmission error is dynamically compensated through a closed-loop feedback mechanism, which can further improve the positioning and cutting accuracy.

The motion gimbal is mounted on the Z-axis motion assembly and can move vertically on it. In this solution, the X-axis motion assembly with synchronous drive from both sides of the slide rails and the Y-axis motion assembly with rigid connecting rods form a closed mechanical frame structure, which improves the torsional stiffness compared to the traditional cantilever beam transmission mechanism. Combined with the high-precision linear guide rail of the Z-axis motion assembly, high-precision three-dimensional linkage positioning is achieved, which can well adapt to the positioning requirements of the control system. Using high-specification drive components, the positioning accuracy can reach the micron level, significantly improving the cutting effect of irregularly shaped vacuum insulation panels and meeting high-standard cutting requirements.

[0019] 4. The elastic buffer at the end of the laser generator can absorb the high-frequency vibration energy during the cutting process. Combined with the vertical guide structure of the Z-axis motion component, it can effectively suppress the focus shift phenomenon and keep the cutting depth tolerance within a small range.

[0020] 5. By using a directional air blowing device, a dynamic air curtain barrier is formed in the cutting kerf during cutting, which can efficiently remove molten residue and volatile organic compounds, effectively control the surface roughness Ra value, reduce the contamination rate of the laser window lens, extend the maintenance cycle of the optical system, and improve work efficiency.

[0021] 6. By setting a vacuum adsorption plate with uniformly distributed adsorption holes on the worktable, a uniform pressure field can be formed, which can improve the uniformity of clamping irregular workpieces and prevent material deformation caused by uneven force during the cutting process.

[0022] 7.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0036] With the increasing demand for energy conservation and environmental protection, vacuum insulation panels (VIPs) are widely used as high-efficiency insulation materials in home appliances, construction, and cold chain logistics. High-precision laser cutting of irregularly shaped workpieces is a crucial step in ensuring product performance during their manufacturing process. However, existing cutting equipment still faces the following technical bottlenecks in practical applications:

[0037] Insufficient positioning accuracy: Traditional cutting equipment mostly uses mechanical limiters or single-point photoelectric sensors for workpiece positioning, which is difficult to meet the three-dimensional spatial positioning requirements of complex contours of irregularly shaped vacuum insulation panels. Especially when switching between multiple batches of workpieces, frequent manual calibration is required, which is not only inefficient, but also prone to uneven cutting edges due to positioning deviations, affecting the sealing performance of the panels.

[0038] Poor dynamic cutting stability: Existing mechanical transmission systems generally adopt a single-sided drive structure, which is prone to harmonic resonance when the XY axes are linked, causing the cutting trajectory to deviate. In addition, the Z-axis lifting mechanism lacks buffer adjustment function, which can easily cause the focal position to shift when dealing with plates of different thicknesses, resulting in inconsistent cutting depths.

[0039] Weak process environment control: Quartz sand particles and volatile organic compounds generated during laser cutting easily adhere to the surface of optical components, affecting energy transmission efficiency. Simultaneously, existing equipment lacks real-time monitoring of the temperature field in the cutting zone. When continuously cutting high-density, irregularly shaped workpieces, localized overheating can easily cause thermal deformation of the core material, reducing product yield.

[0040] Lack of intelligent collaborative capabilities: Traditional control systems mostly adopt open-loop control mode, and there is a lack of data interaction between the positioning device, motion mechanism and laser output unit. It is impossible to dynamically adjust process parameters according to working conditions, and it is difficult to achieve adaptive compensation of trajectory for cutting complex curved surfaces.

[0041] The following is in conjunction with the appendix Figures 1 to 3 The present application provides a detailed description of a vacuum insulation panel laser cutting device 1 through specific embodiments and application scenarios.

[0042] The present invention provides a vacuum insulation panel laser cutting equipment 11, which includes a frame 10, a laser cutting system 11, a mechanical transmission system and a positioning device 13. A worktable 14 is embedded in the frame 10. The mechanical transmission system 12 is disposed on the frame 10. The laser cutting system 11 is slidably disposed on the mechanical transmission system 12. The mechanical transmission system 12 includes an X-axis motion component 120, a Y-axis motion component 121 and a Z-axis motion component 122. The positioning device 13 includes at least two positioning components 130, which are uniformly arranged along the circumference of the frame 10.

[0043] Understandably, this equipment integrates a three-axis linkage mechanical transmission system 12, allowing the laser cutting system 11 to move along the three axes with the mechanical transmission system 12. The cutting position is flexible and adjustable, and the movement is stable, making it well-suited for cutting various irregularly shaped vacuum insulation panels and achieving zero dead angles in the cutting process. At the same time, by evenly distributing the positioning components 130 along the circumference of the frame 10, a multi-angle collaborative positioning reference can be formed, improving positioning accuracy, effectively eliminating the rotational degree of freedom error present in traditional single-point positioning, significantly enhancing the robustness of three-dimensional spatial positioning of irregularly shaped workpieces, and ensuring precise matching between the laser cutting path and the workpiece contour.

[0044] Furthermore, the vacuum insulation panel laser cutting equipment 1 also includes a control system 15, and the positioning device 13 also includes a vision recognition module 131. The vision recognition module 131 is mounted on the frame 10, and the positioning component 130 is an infrared beam sensor. The vision recognition module 131, the positioning component 130, and the mechanical transmission system 12 are electrically connected to the control system 15.

[0045] Understandably, the composite positioning method integrating the visual recognition module 131 and the infrared beam sensor, combined with the data fusion algorithm of the control system 15, can achieve global scanning of workpiece contour features and precise edge positioning. Compared with the single sensing mode, the positioning efficiency is significantly improved. At the same time, the mechanical transmission error is dynamically compensated through the closed-loop feedback mechanism, which can further improve the positioning and cutting accuracy.

[0046] Further, please refer to Figure 1The X-axis motion assembly 120 includes slide rails 1200 respectively disposed on opposite sides of the frame 10, and sliding plates 1201 are slidably disposed on the two slide rails 1200 respectively. The Y-axis motion assembly 121 includes at least two connecting rods 1210, and the opposite ends of the connecting rods 1210 are fixedly connected to the sliding plates 1201. The Z-axis motion assembly 122 is slidably disposed on the connecting rods 1210. The laser cutting system 11 includes a motion gimbal 110 and a laser generating device 111 disposed on the motion gimbal 110. The motion gimbal 110 is disposed on the Z-axis motion assembly 122 and can move vertically on the Z-axis motion assembly 122.

[0047] Understandably, in the vacuum insulation panel laser cutting equipment 1 provided in this embodiment, the X-axis motion component 120 driven synchronously by the double-sided slide rails 1200 and the Y-axis motion component 1210 formed by the rigid connecting rod 1210 form a closed mechanical frame structure, which improves the torsional stiffness compared with the traditional cantilever beam transmission mechanism. At the same time, in conjunction with the high-precision linear guide rail of the Z-axis motion component 122, high-precision three-dimensional linkage positioning is achieved, which can well adapt to the positioning requirements of the control system 15. The high-specification drive component is used, and the positioning accuracy can reach the micron level, which significantly improves the cutting effect of irregular vacuum insulation panels and meets high-standard cutting requirements.

[0048] Specifically, the control system 15 of this equipment is connected to the workshop industrial computer (not shown in the figure). The CAD drawing of the vacuum insulation board is entered into the industrial computer, and the cutting path is automatically planned through the self-developed algorithm. Based on the visual recognition data, a non-uniform rational B-spline (NURBS) cutting path is generated to avoid sudden speed changes at right angle inflection points. At the same time, the laser power and moving speed are adjusted in real time. The heat input is controlled through the PID algorithm, and the heat-affected zone is ≤0.3mm.

[0049] Furthermore, please combine Figure 3 The laser generator 111 has an emitting end 1110 facing the worktable 14 at one end, and an elastic buffer 1111 is provided at the other end.

[0050] Understandably, the elastic buffer 1111 at the end of the laser generator 111 can absorb the high-frequency vibration energy during the cutting process. Combined with the vertical guide structure of the Z-axis motion assembly 122, it can effectively suppress the focus shift phenomenon and control the cutting depth tolerance within a small range.

[0051] Furthermore, a blowing device 1112 is also provided on the side of the laser generator 111 near the emitting end 1110, with the nozzle of the blowing device aimed at the worktable 14.

[0052] Understandably, the directional air blowing device 1112 creates a dynamic air curtain barrier in the cutting seam during cutting, which can efficiently remove molten residue and volatile organic compounds, effectively control the surface roughness Ra value, reduce the contamination rate of the laser window lens, extend the maintenance cycle of the optical system, and improve work efficiency.

[0053] Specifically, a nitrogen or air nozzle is installed on the side of the cutting head, with the air pressure set to 0.2-0.5MPa, to blow away molten slag and protect the lens.

[0054] Furthermore, a vacuum adsorption plate 140 is provided on the workbench 14, and the vacuum adsorption plate 140 is provided with evenly distributed adsorption holes 1400.

[0055] Understandably, by setting a vacuum adsorption plate 140 with evenly distributed adsorption holes 1400 on the worktable 14, a uniform pressure field can be formed, which can improve the uniformity of clamping irregular workpieces and prevent material deformation caused by uneven force during the cutting process.

[0056] Specifically, in order to ensure that the vacuum insulation panel is not damaged by excessive suction, the diameter of the adsorption pore 1400 is ≤1mm, preferably 0.5mm.

[0057] Furthermore, a flexible silicone layer 141 is provided on the surface of the vacuum adsorption plate 140, and the flexible silicone layer 141 has openings corresponding to the adsorption holes 1400.

[0058] Understandably, the flexible silicone layer 141 on the vacuum adsorption plate 140 can provide frictional constraint while having shape self-adaptive characteristics, enhancing the compatibility of clamping workpieces of different thicknesses, and reducing material deformation caused by rigid clamping to the vacuum insulation plate.

[0059] Furthermore, a dust suction port 142 is provided below the workbench 14, and the dust suction port 142 is connected to a filtration system (not shown in the figure).

[0060] Understandably, the dust removal network formed by the suction port 142 and the filtration system can promptly remove dust and harmful gases generated during cutting, improve the internal process environment of the equipment, extend the service life of optical components, reduce dust in the production workshop, and improve the cleanliness of the workshop.

[0061] As an optional implementation, the suction holes 1400 of the vacuum adsorption plate 140 can be integrated with a dust suction function to simplify the equipment.

[0062] Furthermore, the visual recognition module 131 also integrates an infrared thermometer for real-time acquisition of the cut temperature.

[0063] Understandably, the visual recognition module 131 with integrated infrared thermometer can monitor the temperature change of the cutting area in real time, and combined with the control system 15, realize the dynamic adjustment of laser power, improve the adaptability to continuous cutting conditions, and at the same time, it can promptly issue an alarm for abnormal cutting power, reducing the risk of thermal damage to the vacuum insulation board material.

[0064] Furthermore, the laser power of the laser generator 111 is set to 50-200W; setting a certain range of laser power can ensure a safe working environment and reduce the risk of thermal damage to the internal materials of the vacuum insulation panel.
