Description

Technical Field

[0001] This utility model relates to the field of optical device processing technology, specifically to a loading component and laser cutting equipment. Background Technology

[0002] With the development of industries such as automobiles and consumer electronics, the application of curved glass in small precision parts is becoming increasingly widespread. This type of glass is characterized by its small size, small radius of curvature, thinness, and high requirements for cross-sectional precision during cutting. Currently, the industry still uses general curved glass processing solutions for laser cutting of this type of small-sized curved glass.

[0003] In existing technologies, a CNC system controls the laser emitter to maintain a specific compensation angle with the normal direction of the cutting point on the product being processed, and utilizes an intermediate fluid medium to reduce the deflection rate after laser incidence. However, in actual production, during laser cutting of the product, the intermediate fluid medium is prone to sloshing, which can easily lead to a large deviation between the desired cutting line and the actual cutting line. Utility Model Content

[0004] This invention provides a loading component and a laser cutting device to solve the problem that the intermediate medium fluid is prone to shaking, resulting in a large deviation between the desired cutting line and the actual cutting line.

[0005] In a first aspect, the present invention provides a loading assembly, including a main body, a working medium layer, and a fixing part. The main body has a positioning groove. The working medium layer is formed of a transparent fluid and is filled in the positioning groove. At least a portion of the fixing part is a transparent structure, which is correspondingly covered on the positioning groove and abuts against the working medium layer.

[0006] Beneficial effects: By setting up a fixing part, the transparent fluid in the positioning groove is sealed, reducing the sloshing of the transparent fluid during the production process and forming a stable fluid layer between the product to be processed and the transparent structure; at the same time, the fixing part, the working medium layer and the main body are integrated into one unit, preventing the deviation between the expected cutting line and the actual cutting line from being large.

[0007] In one optional embodiment, the positioning groove is suitable for placing the product to be processed, the refractive index of the transparent fluid is n1, and the refractive index of the product to be processed is n2, satisfying |(n2-n1) / n2|×100%<15%.

[0008] Beneficial effects: Strictly controlling the refractive index difference between the transparent fluid and the product to be processed ensures that their optical physical properties are similar, guaranteeing the optical path correction effect.

[0009] In one optional embodiment, the positioning groove is suitable for placing the product to be processed, the refractive index of the transparent structure is n3, and the refractive index of the product to be processed is n2, satisfying |(n2-n3) / n2|×100%<15%.

[0010] Beneficial effects: Strictly control the refractive index difference between the transparent structure and the product to be processed to ensure that their optical physical properties are similar and to guarantee the optical path correction effect.

[0011] In one optional embodiment, the main body includes a plate, a first pipe, and a second pipe. The plate has the positioning groove, and a portion of the first pipe and a portion of the second pipe are disposed within the plate and communicate with the positioning groove respectively.

[0012] Beneficial effects: The first and second pipes are directly integrated into the plate and connected to the positioning groove, providing a built-in circulation channel for the working medium layer, improving the compactness and stability of the overall equipment structure.

[0013] In one alternative embodiment, the loading assembly further includes a speed regulating structure disposed on at least one of the first pipe and the second pipe; and / or, the loading assembly further includes a filter structure and a fluid source having an inlet and an outlet, the first pipe and the second pipe being connected to the inlet and the outlet respectively, and the filter structure being connected to at least one of the first pipe and the second pipe.

[0014] Beneficial effects: By setting up a speed regulation structure, the inflow and outflow speeds of the transparent fluid in the first and second pipes can be precisely controlled, ensuring that the liquid level of the working medium layer in the positioning tank remains stable within the preset range. This avoids problems such as turbulence caused by excessively fast fluid flow and untimely replenishment caused by excessively slow flow, further enhancing the physical stability of the fluid layer and providing a reliable guarantee for optical path correction. The filtration structure can capture glass fragments and impurities in the circulating fluid in real time, maintaining the chemical and optical purity of the working medium layer at all times. The fluid source and the pipes form a closed-loop circulation, which not only avoids fluid waste but also prevents impurities from adhering to the product to be processed, the transparent structure, or the laser optical path, reducing the frequency of equipment cleaning and maintenance costs. At the same time, it ensures that the laser power is not lost, extending the service life of the equipment.

[0015] In one alternative embodiment, the fixing part includes a cover plate that forms the transparent structure, the cover plate being disposed on the positioning groove and abutting against the working medium layer.

[0016] Beneficial effects: The cover plate, as a transparent structure, directly covers and abuts the working medium layer, achieving fluid sealing and blocking external interference on the one hand; on the other hand, its transparency does not affect laser penetration. The cover plate, working medium layer, and product to be processed together construct a stable optical environment, suppressing fluid sloshing from a physical level, reducing optical path deviation, and further reducing the deviation between the desired cutting line and the actual cutting line.

[0017] In one alternative embodiment, the fixing part further includes a fixing block, a portion of which abuts against the side of the cover plate away from the working medium layer, and the fixing block is detachably connected to the main body.

[0018] Beneficial effects: The fixing block presses the cover plate with a detachable connection, further ensuring the sealing fit between the cover plate and the positioning groove and preventing fluid leakage from the gaps.

[0019] In one optional embodiment, the positioning groove includes a receiving groove and a positioning structure. The positioning structure is disposed in the receiving groove, the working medium layer is filled in the receiving groove, the transparent structure is correspondingly covered on the receiving groove, the positioning structure is adapted to place the product to be processed, and the shape of the positioning structure is set to correspond to the outer contour of the product to be processed.

[0020] Beneficial effects: The positioning structure is designed according to the outline of the product to be processed, which can quickly achieve precise positioning of the product, restrict the product's degree of freedom, and avoid product displacement during processing.

[0021] Secondly, this utility model also provides a laser cutting device, including the aforementioned loading assembly.

[0022] In one optional embodiment, the laser cutting equipment further includes a platform, a first moving component, a fixed base, a second moving component, and a laser cutting component; the first moving component is disposed on the platform and has a first moving end; the fixed base is connected to the first moving end, and the loading component is disposed on the fixed base; the second moving component is disposed on the platform and has a second moving end; the laser cutting component includes a laser cutting structure, which is disposed on the second moving end and faces the positioning groove.

[0023] Beneficial effects: The first moving component drives the loading component to achieve precise positioning on the X and Y axes, while the second moving component controls the Z-axis position of the laser cutting structure. The two work together to ensure that the laser cutting structure always faces the processing area in the positioning groove, which can not only meet the cutting requirements of complex contours, but also further improve the plumbness and processing accuracy of the cutting section.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The following is combined with Figures 1 to 8 , Figure 11 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, in a first aspect, a loading assembly is provided, including a main body 10, a working medium layer 20, and a fixing part 30. The main body 10 has a positioning groove 111. The working medium layer 20 is formed of a transparent fluid and is filled in the positioning groove 111. At least a portion of the fixing part 30 is a transparent structure, which is correspondingly covered on the positioning groove 111 and abuts against the working medium layer 20.

[0030] By using the loading assembly of this embodiment, the transparent fluid in the positioning groove 111 is sealed by setting the fixing part 30, which reduces the sloshing of the transparent fluid during the production process and forms a stable fluid layer between the product A to be processed and the transparent structure. At the same time, the fixing part 30, the working medium layer 20 and the main body 10 are integrated as a whole, which prevents the expected cutting line from deviating greatly from the actual cutting line.

[0031] Specifically, in this embodiment, the product A to be processed is curved glass.

[0032] Specifically, in this embodiment, the transparent fluid is a transparent optical correction fluid, and the product A to be processed is immersed in the transparent optical correction fluid.

[0033] In one embodiment, the positioning groove 111 is suitable for placing the product A to be processed. The refractive index of the transparent fluid is n1, and the refractive index of the product A to be processed is n2, satisfying |(n2-n1) / n2|×100%<15%; the refractive index of the transparent structure is n3, satisfying |(n2-n3) / n2|×100%<15%.

[0034] It should be noted that the refractive index of the transparent fluid must be similar to that of the product A to be processed, and it must possess the properties of low reflectivity, high transmittance, and low absorptivity (reflectivity less than 3%, absorptivity less than 5%, transmittance greater than 90%). Low reflectivity and high transmittance ensure the energy efficiency of the entire system; the higher the transmittance of the transparent fluid, the less energy is lost when the laser reaches the material being processed. With a fixed laser power of 82, more energy reaches the product A, allowing for increased cutting speed and thus increased production capacity. If the absorptivity of the transparent fluid is too high, due to the thermal expansion effect, laser energy is absorbed, the liquid temperature rises, and uneven thermal expansion occurs. This slight deformation can cause positional shifts in the laser during transmission, interfering with the processing of product A. Similarly, the refractive index of the transparent structure must be similar to that of the product A to be processed, and it must possess the properties of low reflectivity, high transmittance, and low absorptivity.

[0035] It is worth noting that the refractive index difference between the transparent fluid, the transparent structure, and the product A to be processed must be strictly controlled to ensure that their optical physical properties are similar and to guarantee the optical path correction effect.

[0036] Specifically, in this embodiment, such as Figure 6 As shown, the fixing part 30 includes a cover plate 31, which forms a transparent structure. The cover plate 31 is correspondingly placed on the positioning groove 111 and abuts against the working medium layer 20.

[0037] It should be noted that in other alternative embodiments, the cover plate 31 may also be set as a transparent structure only at the position corresponding to the positioning groove 111.

[0038] It is worth noting that the cover plate 31, as a transparent structure, directly covers and abuts the working medium layer 20. On the one hand, it achieves fluid sealing and blocks external interference; on the other hand, its transparency does not affect laser penetration. The cover plate 31, the working medium layer 20, and the product A to be processed together construct a stable optical environment, which physically suppresses fluid sloshing, reduces optical path deviation, and further reduces the deviation between the desired cutting line and the actual cutting line.

[0039] Furthermore, such as Figure 6 As shown, the fixing part 30 also includes a fixing block 32, a portion of which abuts against the side of the cover plate 31 away from the working medium layer 20, and the fixing block 32 is detachably connected to the main body 10.

[0040] Specifically, such as Figure 6 As shown, there are two fixing blocks 32, and the two fixing blocks 32 abut against the two ends of the main body 10 respectively.

[0041] It is worth noting that the fixing block 32 presses the cover plate 31 with a detachable connection, further ensuring the sealing fit between the cover plate 31 and the positioning groove 111, and preventing fluid leakage from the gap.

[0042] Furthermore, such as Figures 1 to 4 As shown, the fixing part 30 also includes a fastener. The fixing block 32 has a through hole 321 and the main body 10 has a threaded hole 14. The fastener passes through the through hole 321 and is fastened in the threaded hole 14.

[0043] Specifically, in this embodiment, the fastener is a bolt, which passes through the through hole 321 on the fixing block 32 and is locked in the threaded hole 14 on the main body 10.

[0044] It is worth noting that the detachable nature of the threaded connection not only facilitates the replacement of cover plates 31 of different specifications according to the product A to be processed, but also facilitates the cleaning and maintenance of the positioning groove 111 and cover plates 31 in the later stage; at the same time, by controlling the tightening torque of the fasteners, the pressure of cover plate 31 on working medium layer 20 can be precisely adjusted to avoid excessive pressure causing fluid overflow or insufficient pressure affecting the sealing effect, thus ensuring the consistency of the processing.

[0045] It should be noted that in laboratory settings or actual production processes, the cutting of curved glass typically considers laser incidence perpendicular to the material, i.e., normal incidence, to eliminate the influence of the laser incident angle on the laser absorption rate and the influence of the glass refractive index on the laser cutting trajectory. However, for cutting curved glass products requiring a plumb line, normal incidence cannot meet the requirements. For example... Figure 9 and Figure 10 As shown in the figure, the diagram illustrates two laser cutting methods without the use of a mounting component. If the incident laser is directly perpendicular to the ground, the laser and the normal phase of the curved glass are incident at a certain angle θ1. According to the law of refraction, n1sinθ1=n2sinθ2, due to the difference between the refractive index of air and the refractive index of glass, there is a certain difference between the expected cutting line and the actual cutting line. The perpendicularity is about ±10°, which cannot meet the product's perpendicularity requirements.

[0046] Therefore, in this application, by setting the working medium layer 20, the deflection rate after laser incident is reduced, and by fixing part 30, the transparent fluid in the positioning groove 111 is sealed, reducing the sloshing of the transparent fluid during the production process, so that a stable fluid layer is formed between the product to be processed A and the transparent structure. The fixing part 30, the working medium layer 20 and the main body 10 are integrated as a whole, preventing the occurrence of a large deviation between the expected cutting line and the actual cutting line.

[0047] It should be noted that, as Figure 8 The diagram shown illustrates the processing in the differential state. Assuming the curved glass is infinitely subdivided (in the differential state), the state of the curved glass is as follows: Figure 8As shown (infinitely close to a flat glass), when an optical correction fluid with a similar refractive index is flowed into it, it can be regarded as a "whole" with similar optical physical properties. The cutting line is at an angle θ2 with the normal phase of the curved glass. The closer n1 and n2 are, the closer θ1 and θ2 are, and the closer the actual cutting line is to the desired cutting line, achieving a cross-section that is approximately perpendicular to the ground.

[0048] like Figure 7 As shown, this is a schematic diagram of the laser processing of the loading component of this utility model. After the transparent correction fluid fills the entire positioning groove 111, the laser cutting structure 81 cuts perpendicular to the plane of the transparent correction fluid. The curved glass arc surface faces down, and the surface is covered with a fixing part 30 to solve the problems of transparent correction fluid shaking and surface unevenness. The focal length and focal height are controlled to make the focal point lower than the surface and prevent damage from the fixing part 30.

[0049] In one embodiment, such as Figure 5 As shown, the positioning groove 111 includes a receiving groove 1111 and a positioning structure 1112. The positioning structure 1112 is disposed in the receiving groove 1111. The working medium layer 20 is filled in the receiving groove 1111. A transparent structure is correspondingly covered on the receiving groove 1111. The positioning structure 1112 is suitable for placing the product A to be processed. The shape of the positioning structure 1112 is set to correspond to the outer contour of the product A to be processed.

[0050] Specifically, two through holes 15 are provided in the receiving tank 1111, and the first pipe 12 and the second pipe 13 are respectively connected to the two through holes 15 to realize the inflow and outflow of transparent fluid.

[0051] It should be noted that, in addition to restricting the product A to be processed through the positioning mechanism, the displacement of the product A to be processed can also be limited by the wall of the receiving tank 1111.

[0052] It is worth noting that the positioning structure 1112 is designed according to the outline of the product A to be processed, which can quickly achieve precise positioning of the product, restrict the product's degree of freedom, and prevent the product from shifting during processing.

[0053] In one embodiment, such as Figures 1 to 4 As shown, the main body 10 includes a plate 11, a first pipe 12 and a second pipe 13. A positioning groove 111 is provided on the plate 11. Part of the first pipe 12 and part of the second pipe 13 are disposed in the plate 11 and are respectively connected to the positioning groove 111.

[0054] Specifically, the first pipe 12 and the second pipe 13 are directly integrated into the plate 11 and connected to the positioning groove 111, providing a built-in circulation channel for the working medium layer 20, thereby improving the compactness and stability of the overall structure of the equipment.

[0055] In one embodiment, such as Figure 11 As shown, the loading assembly also includes a filter structure 40 and a fluid source (not shown). The fluid source has an inlet and an outlet. The first pipe 12 and the second pipe 13 are respectively connected to the inlet and the outlet. The filter structure 40 is connected to the first pipe 12.

[0056] Specifically, the fluid source contains a transparent fluid, and the filter structure 40 is a filter responsible for capturing nanoscale glass debris to ensure the optical purity of the working medium layer 20, thereby not damaging the laser power and maintaining long-term process stability.

[0057] Specifically, the first pipe 12 is connected to the inlet of the fluid source, and the second pipe 13 is connected to the outlet. The transparent fluid flows into the positioning groove 111 through the first pipe 12 and flows back to the fluid source through the second pipe 13.

[0058] It should be noted that in other alternative embodiments, the filter structure 40 may also be connected to the second pipe 13, or the filter structure 40 may also be connected to the first pipe 12 and the second pipe 13 respectively, to further improve the filtration effect.

[0059] It is worth noting that the filter structure 40 can capture glass fragments and impurities in the circulating fluid in real time, and always maintain the chemical and optical purity of the working medium layer 20. The fluid source and the pipeline form a closed loop circulation, which not only avoids fluid waste, but also prevents impurities from adhering to the product A to be processed, the transparent structure or the laser optical path, reducing the frequency of equipment cleaning and maintenance costs, while ensuring that the laser power is not lost and extending the service life of the equipment.

[0060] It is worth noting that the fluid source and the pipeline form a closed loop, which can also remove heat in time and protect the product A to be processed.

[0061] In one embodiment, the loading assembly further includes a speed regulating structure disposed on the first pipe 12.

[0062] Specifically, in this embodiment, the speed control structure is a speed control valve, which controls the first pipe 12. Since the first pipe 12, the second pipe 13 and the fluid source form a closed loop, the speed control valve can control the flow rate in the entire circulation channel.

[0063] It should be noted that in other alternative embodiments, the speed regulating structure may also be provided on the second pipe 13, or the speed regulating structure may also be provided on the first pipe 12 and the second pipe 13 respectively.

[0064] Specifically, the speed control valve controls the inflow speed of the first pipe 12 and the outflow speed of the second pipe 13 until the transparent fluid stably covers the surface of the product A to be processed by about 1 mm. Then, the fixing part 30 abuts against the surface of the transparent fluid to form a stable fluid layer.

[0065] It is worth noting that by setting a speed regulation structure, the inflow and outflow speeds of the transparent fluid in the first pipe 12 and the second pipe 13 can be precisely controlled, ensuring that the liquid level of the working medium layer 20 in the positioning tank 111 is stable within the preset range. This avoids the problem of turbulence caused by excessively fast fluid flow and untimely replenishment caused by excessively slow fluid flow, further enhancing the physical stability of the fluid layer and providing a reliable guarantee for optical path correction.

[0066] Using the loading assembly of this embodiment, firstly, the product A to be processed is placed on the positioning mechanism; then, transparent fluid is injected into the receiving tank 1111 to form a working medium layer 20; after that, the cover plate 31 is closed and further fixed by the fixing block 32; the flow speed of the transparent fluid is adjusted by the speed regulating structure to ensure that the transparent fluid stably covers the surface of the product A to be processed.

[0067] According to an embodiment of the present invention, in a second aspect, a laser cutting device is also provided, including the loading assembly described above.

[0068] In one embodiment, such as Figure 11 As shown, the laser cutting equipment also includes a platform 50, a first moving component 61, a fixed base 70, a second moving component 62, and a laser cutting component 80; the first moving component 61 is disposed on the platform 50 and has a first moving end; the fixed base 70 is connected to the first moving end, and the loading component is disposed on the fixed base 70; the second moving component 62 is disposed on the platform 50 and has a second moving end; the laser cutting component 80 includes a laser cutting structure 81, which is disposed on the second moving end and faces the positioning groove 111.

[0069] Specifically, the laser cutting assembly 80 also includes a laser 82 and a reflective optical path structure 83. The laser light emitted from the laser 82 reaches the cutting head through the reflective optical path structure 83 to cut the product.

[0070] Specifically, the first moving component 61 is an X and Y axis moving component, and the first moving end can move in the X and Y axis directions of the platform; the second moving component 62 is a Z axis moving component, and the second moving end can move in the Z axis direction of the platform.

[0071] It is worth noting that the first moving component 61 drives the loading component to achieve precise positioning on the X and Y axes, while the second moving component 62 controls the Z-axis position of the laser cutting structure 81. The two work together to ensure that the laser cutting structure 81 always faces the processing area in the positioning groove 111, which can not only meet the cutting requirements of complex contours, but also further improve the plumbness and processing accuracy of the cutting section.

[0072] In one embodiment, such as Figure 11 As shown, the laser cutting equipment also includes a vision positioning component 90, which has an image acquisition head and is signal-connected to the moving component.

[0073] It is worth noting that the image acquisition head of the vision positioning component 90 can capture the actual position of the product A to be processed in the positioning groove 111 in real time, accurately identify the product outline and placement deviation, avoid errors in manual or mechanical positioning (such as slight offset of tooling positioning), and provide a precise position reference for subsequent laser cutting.

[0074] The laser cutting equipment of this embodiment uses a first mobile end to move the loading component on the fixed base 70 to below the image acquisition head of the vision positioning component 90 for edge tracking and positioning. After the positioning and capture are completed, the laser 82 emits light through the reflection optical path structure 83 to reach the cutting head for product cutting.
