Abstract
Description
Technical Field
[0001] This invention relates to the field of laser cutting, and specifically to a dynamic obstacle avoidance support platform for laser cutting and its usage method. Background Technology
[0002] When laser cutting equipment processes wood, acrylic, MDF, advertising boards, and other flat panels, a support structure is typically required on the worktable to support and position the material to be cut. A common support method in existing laser cutting equipment involves installing fixed blades, fixed support strips, or a fixed grid table within the worktable, with several fixed support components supporting the bottom of the panel. This type of support structure is relatively simple to process and install, and can meet the needs of placing ordinary panels and providing support for general cutting, thus it is widely used in existing laser cutting equipment.
[0003] However, in actual laser cutting, after the laser beam penetrates the material being cut, it continues to act downwards on the worktable support structure. Since the positions of existing fixed blades or fixed grid support structures are usually not adjustable, the support points cannot actively avoid the laser cutting path based on the specific layout, resulting in fixed support components often existing below the laser cutting line. When the laser penetrates the material and directly irradiates the fixed support components, these components are subjected to high temperatures and generate reverse heat radiation, smoke, oxides, or slag, causing secondary pollution and thermal damage to the bottom surface of the material. This makes the bottom surface of the processed material prone to problems such as yellowing, blackening, burn marks, slag buildup, rough edges, or localized carbonization. For products such as acrylic, wood panels, decorative panels, and advertising panels, which have high requirements for appearance quality, these problems directly affect the appearance of the finished product, usually requiring subsequent manual sanding, cleaning, or rework, increasing labor costs and processing time.
[0004] Meanwhile, the fixed support structure, being constantly positioned below the laser cutting area, is susceptible to repeated laser ablation, leading to oxidation, pitting, deformation, warping, or localized ablation. Deformation of the support structure affects the overall flatness of the worktable, causing instability in the placement of the material to be cut. This can result in problems such as dimensional deviations in cutting, localized sagging of the material, uneven cutting edges, interference with the cutting head, and even equipment shutdown alarms. Especially in high-frequency continuous processing scenarios, the fixed support structure wears out quickly, requiring regular replacement, leveling, or maintenance, increasing equipment downtime and maintenance costs.
[0005] Furthermore, the support spacing of existing fixed blade or fixed grid support structures is generally determined at the factory or during installation, making it difficult to flexibly adjust according to different sheet sizes, thicknesses, hardnesses, cutting patterns, and layout methods. When processing smaller sheets or patterns with dense cutting paths, the fixed supports are prone to coinciding with the laser cutting path; when processing larger or thinner sheets, the fixed support points may not form a suitable stress distribution, leading to localized suspension, sagging, warping, or vibration of the sheet. For processing scenarios involving irregular contours, multiple holes, multiple slits, or multiple workpieces arranged for cutting, fixed support structures find it even more difficult to effectively avoid interference with the cutting path, failing to simultaneously meet the requirements of support stability and preventing laser burning of the support components.
[0006] Therefore, existing laser cutting support platforms still suffer from problems such as fixed support points, inability to avoid the laser cutting path, susceptibility to backburn contamination of the bottom surface of the sheet material, easy ablation and deformation of the support structure, insufficient adaptability to different sheet materials, and inconvenience in maintenance and replacement. How to provide a dynamic avoidance support platform that can adjust the support points according to the sheet material size and laser cutting path, while ensuring stable load-bearing of the sheet material and allowing the support structure to avoid the laser's downward trajectory, has become a pressing technical problem to be solved in this field. Summary of the Invention
[0007] To address the aforementioned problems, this invention provides a dynamic obstacle avoidance support platform and its usage method for laser cutting, which effectively overcomes the shortcomings of existing technologies.
[0008] The present invention is achieved through the following technical solution: a dynamic avoidance support platform for laser cutting, comprising a bearing base, multiple first-direction adjustable support members, multiple second-direction adjustable support units, and a positioning and locking assembly; The plurality of first-direction adjustable support members are movably disposed on the bearing base and can be adjusted relative to the bearing base along the first direction to change the support spacing between adjacent first-direction adjustable support members. The plurality of second-direction adjustable support units are movably disposed on the corresponding first-direction adjustable support members, and can adjust their positions relative to the first-direction adjustable support members along the second direction to change the support point position of each second-direction adjustable support unit on the corresponding first-direction adjustable support member. The first direction and the second direction are intersecting, so that multiple adjustable support units in the second direction can form an adjustable point support layout within the bearing area of the bearing base; The positioning and locking assembly is used to position and fix the first direction adjustable support member and / or the second direction adjustable support unit after they are adjusted into place. The first adjustable support member and the second adjustable support unit can be positioned according to the size, placement and laser cutting path of the plate to be cut, so that the second adjustable support unit avoids the corresponding area of the laser cutting path in the bearing area and forms an unsupported avoidance space below the laser cutting path, so as to prevent the laser from penetrating the plate to be cut and directly acting on the support structure.
[0009] As a preferred technical solution, the bearing base is a closed-loop integral load-bearing outer frame base, which forms a load-bearing area with a hollow center, and the first direction adjustable support is disposed in the load-bearing area of the closed-loop integral load-bearing outer frame base.
[0010] As a preferred technical solution, the closed-loop integral load-bearing outer frame base is provided with a transverse support guide rod, and the plurality of first-direction adjustable support members are respectively movably installed on the transverse support guide rod and can be adjusted in position along the transverse support guide rod.
[0011] As a preferred technical solution, the first directional adjustable support member is a transversely sliding grid main beam. Multiple transversely sliding grid main beams are spaced apart within the closed-loop integral load-bearing outer frame base, and the spacing between adjacent transversely sliding grid main beams can be changed by moving relative to the transverse support guide rod.
[0012] As a preferred technical solution, the second directional adjustable support unit is a longitudinally independently sliding support column unit, and each of the transversely sliding grid main beams is provided with one or more longitudinally independently sliding support column units, which can be moved and adjusted along the corresponding transversely sliding grid main beam.
[0013] As a preferred technical solution, the longitudinal independently sliding support column unit and the transversely sliding grid main beam form a sliding limiting fit, so that the longitudinal independently sliding support column unit can move and adjust relative to the transversely sliding grid main beam, and maintain the connection state with the transversely sliding grid main beam during the movement and adjustment process.
[0014] As a preferred technical solution, the top of the longitudinally independent sliding support column is provided with an anti-slip support head, which is used to contact the bottom surface of the plate to be cut in order to form point support for the plate to be cut.
[0015] As a preferred technical solution, the positioning and locking assembly includes a main beam locking member for positioning and fixing the transversely sliding grid main beam, and a support column locking member for positioning and fixing the longitudinally independently sliding support column. The main beam locking member and the support column locking member restrict the continued movement of the corresponding components after they are adjusted into place.
[0016] A method for using a dynamic obstacle avoidance support platform for laser cutting according to the present invention includes the following steps: Obtain the dimensions, placement, and laser cutting path of the material to be cut; Based on the size information of the plate to be cut, the positions of multiple first-direction adjustable support members relative to the bearing base are adjusted so that the multiple first-direction adjustable support members form a support spacing that is compatible with the plate to be cut. Based on the corresponding area of the laser cutting path within the bearing area, the positions of multiple second-direction adjustable support units relative to the corresponding first-direction adjustable support members are adjusted so that at least some of the second-direction adjustable support units avoid the corresponding area of the laser cutting path within the bearing area. Position and fix the first-direction adjustable support and / or the second-direction adjustable support unit that have been adjusted to the correct position; The material to be cut is placed on multiple second-direction adjustable support units for laser cutting, so that the laser penetrates the material to be cut and enters the unsupported clearance space formed by the second-direction adjustable support units.
[0017] As a preferred technical solution, the bearing base is a closed-loop integral load-bearing outer frame base, the first direction adjustable support component is a transversely sliding grid main beam, and the second direction adjustable support unit is a longitudinally independently sliding support column unit. In use, the positions of multiple transversely sliding grid main beams relative to the closed-loop integral load-bearing outer frame base are adjusted to adapt to the size of the plate to be cut, and the positions of multiple longitudinally independently sliding support column units relative to the transversely sliding grid main beams are adjusted so that the longitudinally independently sliding support column units are arranged in the solid area of the plate to be cut, the blank area between adjacent laser cutting lines, the outer area of the workpiece contour, or the non-cutting landing point area.
[0018] The beneficial effects of this invention are as follows: By setting up a bearing base, multiple first-direction adjustable support members, multiple second-direction adjustable support units, and a positioning and locking assembly, this invention allows the support platform to move away from the traditional single support method of fixed blades or fixed grids, and instead form an adjustable support layout combining the first and second directions. The first-direction adjustable support members can adjust their positions relative to the bearing base, and the second-direction adjustable support units can adjust their positions independently relative to the first-direction adjustable support members. This allows multiple support points to be rearranged within the bearing area according to the size of the material to be cut, its placement position, and the laser cutting path. Compared to traditional support structures, this invention can improve the overall adjustability of the support platform, freeing the support point positions from the limitations of fixed blade positions.
[0019] This invention can pre-adjust the position of the second-direction adjustable support unit according to the laser cutting path, so that the support point avoids the corresponding area of the laser cutting path within the bearing area, and forms an unsupported clearance space below the laser cutting path. Therefore, after the laser penetrates the material to be cut, it is less likely to directly irradiate the support structure, reducing or avoiding reverse heat radiation, smoke, slag, and oxidation pollution caused by laser burning of the support structure from the source. This effectively reduces the risk of yellowing, blackening, burning, slag buildup, and carbonization of the bottom surface of the material, improves the cleanliness and appearance quality of the laser-cut finished product, and reduces subsequent manual grinding, cleaning, or rework.
[0020] This invention enables the support structure to actively avoid the laser's downward trajectory, significantly reducing the probability of direct laser ablation. This minimizes problems such as ablation, dents, deformation, oxidation, and wear on the support components, thus helping to maintain the flatness and stability of the support platform over long-term use. The support platform is less prone to affecting the placement accuracy of the sheet metal due to localized ablation and deformation, and is less likely to cause cutting errors or equipment interference due to uneven support surfaces. This improves the continuous operational stability of laser cutting equipment and reduces downtime maintenance costs caused by table damage, leveling, calibration, or replacement.
[0021] The first-direction adjustable support member of this invention can adjust the support spacing according to the size of the sheet metal, and the second-direction adjustable support unit can adjust the point distribution according to the cutting pattern and support requirements. Therefore, it can adapt to the processing needs of sheets of different specifications, thicknesses, shapes, and layouts. For large-size sheets, the load uniformity can be improved by adjusting the support points, reducing sheet sagging and vibration. For small-size sheets or densely cut patterns, the support points can be avoided in the cutting line area to reduce support interference. For irregularly shaped sheets, the support points can be flexibly arranged according to the contour boundary and cutting gap, giving the support platform better versatility and adaptability.
[0022] This invention uses a positioning and locking assembly to position and fix the first-direction adjustable support member and the second-direction adjustable support unit after they have been adjusted to their positions. This ensures that the support points remain stable after the avoidance arrangement is completed, preventing the support accuracy of the sheet metal from being affected by the displacement, shaking, or loosening of the support members during the cutting process. This structure can achieve flexible adjustment of the support points while ensuring the load-bearing reliability during the cutting process, thus balancing the functions of dynamic avoidance and stable support.
[0023] In a specific implementation, this invention can be implemented by setting the load-bearing base as a closed-loop integral load-bearing outer frame base, setting the first-direction adjustable support component as a transversely sliding grid main beam, setting the second-direction adjustable support unit as a longitudinally independently sliding support column, and setting an anti-slip support head on the top of the longitudinally independently sliding support column. This structure, while ensuring overall load-bearing strength, enables lateral adjustment of the transversely sliding grid main beam relative to the closed-loop integral load-bearing outer frame base, and longitudinal independent adjustment of the longitudinally independently sliding support column relative to the transversely sliding grid main beam, thus forming a bidirectional sliding and avoidance layout combining lateral and longitudinal movements. The anti-slip support head provides stable point support to the bottom surface of the material to be cut, reducing slippage, displacement, or localized instability of the material during the cutting process.

Detailed Implementation
[0026] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0027] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0028] like Figure 1 and Figure 2As shown, this embodiment provides a dynamic avoidance support platform for laser cutting. This support platform is installed within the working area of the laser cutting equipment and is used to support wooden boards, acrylic boards, MDF boards, advertising boards, decorative boards, or other flat boards during laser cutting operations. This support platform does not use the traditional fixed blade or fixed grid table support method. Instead, it uses adjustable support components to form a dynamic support layout that can be rearranged according to the board size, board placement, and laser cutting path. This ensures that the board to be cut is reliably supported while the support points actively avoid the area below the laser cutting line, thereby preventing problems such as backburning, blackening, slag buildup, or support component ablation caused by the laser directly irradiating the support structure after penetrating the board.
[0029] This dynamic obstacle avoidance support platform for laser cutting includes a closed-loop integral load-bearing outer frame base 1, a transversely sliding grid main beam 2, transverse support guide rods 3, independently sliding support column units 4, and anti-slip support heads 5. The closed-loop integral load-bearing outer frame base 1 serves as the basic load-bearing structure of the entire platform. Its overall closed-loop frame structure provides a stable installation and load-bearing foundation for the transversely sliding grid main beam 2, the independently sliding support column units 4, and the material to be cut. A load-bearing area is formed in the middle of the closed-loop integral load-bearing outer frame base 1, which corresponds to the processing area of the laser cutting equipment, allowing the material to be cut to be placed within the area defined by the closed-loop integral load-bearing outer frame base 1. The closed-loop integral load-bearing outer frame base 1 can be made of a metal frame with sufficient rigidity and load-bearing strength to ensure that it is not prone to overall twisting, sinking, or deformation during long-term load-bearing and cutting processes, thereby maintaining the overall flatness and operational stability of the platform.
[0030] A transverse support guide rod 3 is provided on the closed-loop integral load-bearing outer frame base 1. The transverse support guide rod 3 is used to guide and support the transversely sliding grid main beam 2, allowing the transversely sliding grid main beam 2 to be adjusted in position relative to the closed-loop integral load-bearing outer frame base 1. The transverse support guide rod 3 can be arranged along the length of the closed-loop integral load-bearing outer frame base 1, or it can be arranged along the opposite sides of the load-bearing area according to the actual structure of the platform, so that the transversely sliding grid main beam 2 can move smoothly under the support and guidance of the transverse support guide rod 3. With the setting of the transverse support guide rod 3, the transversely sliding grid main beam 2 does not need to be permanently fixed to the closed-loop integral load-bearing outer frame base 1 by welding. Instead, its transverse position can be adjusted according to different plate sizes and cutting layout requirements, thereby changing the spacing between adjacent transversely sliding grid main beams 2.
[0031] Multiple horizontally sliding grid main beams 2 are configured and installed at intervals within the load-bearing area of the closed-loop integral load-bearing outer frame base 1. Each horizontally sliding grid main beam 2 serves as an adjustable support component in the first direction, forming a basic support skeleton on the platform. A movable engagement relationship is formed between the horizontally sliding grid main beam 2 and the horizontal support guide rod 3, allowing the horizontally sliding grid main beam 2 to move and adjust its position along the horizontal support guide rod 3. In actual use, when the width and weight of the plate to be cut are large, or when it is necessary to improve the overall support stability, the spacing between the multiple horizontally sliding grid main beams 2 can be appropriately adjusted to form a support layout more suitable for the stress state of the plate. When the size of the plate to be cut is small or the laser cutting path is dense, the horizontally sliding grid main beams 2 can be moved to avoid areas that easily overlap with the laser cutting path, thereby reducing the possibility of the horizontally sliding grid main beam 2 being directly burned by the laser.
[0032] Multiple independently sliding support column units 4 are configured, with one or more independently sliding support column units 4 installed on each transversely sliding grid main beam 2. Each independently sliding support column unit 4 serves as a second-direction adjustable support unit, installed on the corresponding transversely sliding grid main beam 2 and capable of moving and adjusting relative to it. The movement direction of the independently sliding support column unit 4 intersects with the movement direction of the transversely sliding grid main beam 2 relative to the closed-loop integral load-bearing outer frame base 1, enabling the platform to achieve composite adjustment capabilities in both directions. By adjusting the position of the transversely sliding grid main beam 2 on the closed-loop integral load-bearing outer frame base 1, the arrangement of the support frame in one direction can be changed; by adjusting the position of the independently sliding support column unit 4 on the transversely sliding grid main beam 2, the arrangement of specific support points in another direction can be changed. This allows multiple independently sliding support column units 4 to form an adjustable and reconfigurable point support layout within the load-bearing area.
[0033] The independently sliding support column 4 forms a sliding limiting fit with the transversely sliding grid main beam 2. This sliding limiting fit allows the independently sliding support column 4 to move along the corresponding transversely sliding grid main beam 2, while maintaining its connection with the transversely sliding grid main beam 2 during movement and adjustment, preventing the independently sliding support column 4 from detaching from the transversely sliding grid main beam 2 during pushing, adjusting, or supporting the plate. Through this sliding limiting fit structure, the independently sliding support column 4 can flexibly move to the solid area of the plate, the blank area between adjacent laser cutting lines, the outer area of the workpiece contour, or the non-cutting point area according to the specific cutting path, thereby avoiding the area below the laser cutting path. Since each independently sliding support column 4 can be adjusted independently, multiple independently sliding support column 4s on the same transversely sliding grid main beam 2 can form support points with different spacing and positions according to different cutting patterns, without needing to move synchronously as a whole, and are not limited by the position of the fixed blade.
[0034] The anti-slip support head 5 is located on top of the independently sliding support column 4. The anti-slip support head 5 contacts the bottom surface of the material to be cut and provides point support. The anti-slip support head 5 can be fixedly connected to the independently sliding support column 4, or it can be detachably installed on the independently sliding support column 4 for replacement after wear. The anti-slip support head 5 improves the stability of the independently sliding support column 4 in supporting the bottom surface of the material, reducing slippage, swaying, or localized displacement of the material during laser cutting due to equipment vibration, airflow impact, or changes in cutting stress. The anti-slip support head 5 also ensures a relatively stable contact between the support point and the bottom surface of the material, allowing the material to maintain good flatness even with localized point support, thus helping to ensure the dimensional accuracy and edge quality of laser cutting.
[0035] To ensure that the adjusted support positions do not shift during the cutting process, the support platform is also equipped with a positioning and locking assembly. This assembly is used to fix the transversely sliding grid main beam 2 and the independently sliding support column 4 after they have been adjusted to their positions. The positioning and locking assembly may include a main beam locking member for fixing the transversely sliding grid main beam 2, and a support column locking member for fixing the independently sliding support column 4. The main beam locking member restricts further movement of the transversely sliding grid main beam 2 after it has been adjusted to the appropriate position along the transverse support guide rod 3, thus maintaining a stable support spacing between adjacent transversely sliding grid main beams 2. The support column locking member restricts further movement of the independently sliding support column 4 after it has been adjusted to the appropriate position along the transversely sliding grid main beam 2, thus maintaining stability at each support point during laser cutting. Through the positioning and locking assembly, the support platform possesses both adjustment flexibility and sufficient support stability and positional reliability during actual processing.
[0036] In practical use, operators can first determine the adjustment scheme of the support platform based on the size, thickness, placement position, and laser cutting layout of the sheet material to be cut. The size of the sheet material determines the approximate layout range and support spacing of the horizontally sliding grid main beams 2, while the laser cutting path determines the area that the independently sliding support column 4 should avoid. Based on the sheet material size, operators move multiple horizontally sliding grid main beams 2 along the horizontal support guide rod 3, so that the multiple horizontally sliding grid main beams 2 form a basic support layout adapted to the sheet material within the closed-loop integral load-bearing outer frame base 1. When the sheet material size is large, the horizontally sliding grid main beams 2 can be distributed relatively evenly to improve the overall load-bearing stability of the sheet material; when the sheet material size is small or the cutting area is concentrated, the position of the horizontally sliding grid main beams 2 can be adjusted to avoid areas with dense laser cutting lines as much as possible.
[0037] After adjusting the position of the transversely sliding grid main beam 2, the multiple independently sliding support columns 4 are adjusted individually or in groups according to the corresponding positions of the laser cutting path within the load-bearing area. For areas corresponding to the laser cutting path, the operator can move the independently sliding support column 4 outside the laser cutting path, creating an unsupported clearance space below that area. For solid areas of the sheet metal, blank areas between adjacent cutting lines, or areas outside the workpiece contour, the independently sliding support column 4 can be appropriately arranged to provide stable support to the sheet metal through the anti-slip support head 5. In this way, the support structure will not be directly below the laser cutting path, and the laser can enter the unsupported clearance space after penetrating the sheet metal, instead of directly irradiating the transversely sliding grid main beam 2 or the independently sliding support column 4, thereby effectively reducing the reverse heat radiation, smoke, slag, and oxidation pollution generated by laser burning on the support structure.
[0038] After the transversely sliding grid main beam 2 and the independently sliding support column 4 are both adjusted into position, the operator uses the positioning and locking components to fix them in place. The main beam locking component locks the transversely sliding grid main beam 2, preventing it from shifting along the transverse support guide rod 3 during subsequent plate placement and cutting. The support column locking component locks the independently sliding support column 4, preventing it from sliding along the transversely sliding grid main beam 2 when bearing the weight of the plate and cutting vibrations. After locking, the plate to be cut is placed stably on multiple anti-slip support heads 5. The anti-slip support heads 5 provide multiple points of support to the bottom surface of the plate to be cut, ensuring that the plate remains stable within the load-bearing area.
[0039] After the laser cutting equipment is started, the laser cuts the material to be cut according to the preset cutting path. Because the independently sliding support column 4 has been adjusted to avoid interference with the laser cutting path before cutting, after the laser penetrates the material, the space below it is formed by the avoidance of support points, rather than a traditional fixed blade or fixed support point. This reduces or avoids direct laser action on the support structure, thereby lowering the probability of the support structure being ablated, oxidized, deformed, or producing slag. Simultaneously, since the support structure is not directly burned by the laser, the bottom surface of the material is less susceptible to the effects of reverse heat radiation and smoke pollution from the support structure, thus improving problems such as blackening, yellowing, slag buildup, and burns on the bottom surface of the material, and improving the appearance quality of the finished product.
[0040] For different types of sheet materials, the support platform in this embodiment can also be adjusted to form different support states. When processing thin sheet materials, the dispersion range of the independently sliding support column 4 can be appropriately increased to obtain more uniform point support on the bottom surface of the sheet material, reducing the sagging, warping or local vibration of the thin sheet material; when processing thick sheet materials, the arrangement density of the independently sliding support column 4 can be appropriately increased in the main load-bearing area to improve load-bearing stability; when processing irregular contour workpieces, multi-hole workpieces or workpieces with multiple cutting gaps, the independently sliding support column 4 can be arranged around the cutting line, hole position and contour boundary, in the solid area of the sheet material or the non-cutting point area, thereby taking into account both the sheet material support stability and the laser path avoidance requirements.
[0041] In this embodiment, a dynamic support structure is formed by the closed-loop integral load-bearing outer frame base 1, the transversely sliding grid main beam 2, the transverse support guide rod 3, the independently sliding support column unit 4, and the anti-slip support head 5, which works in conjunction with overall load-bearing, first-direction adjustment, second-direction adjustment, and point-position support. The closed-loop integral load-bearing outer frame base 1 provides the overall load-bearing foundation, the transverse support guide rod 3 provides the movement guide for the transversely sliding grid main beam 2, the transversely sliding grid main beam 2 provides an adjustable foundation support frame, the independently sliding support column unit 4 provides independent point-position support that can avoid the laser path, and the anti-slip support head 5 improves the stability of the support contact with the bottom surface of the plate. Through the above structural cooperation, the support platform can reconstruct the support points according to each processing task, no longer limited by the position of the traditional fixed blade, thereby realizing the active avoidance of the laser path by the support structure during laser cutting.
[0042] During long-term use, if any of the independently sliding support columns 4 or anti-slip support heads 5 wear out, only the corresponding components need maintenance or replacement, without requiring the complete disassembly of the closed-loop load-bearing outer frame base 1 or replacement of the entire platform. Since both the transversely sliding grid main beam 2 and the independently sliding support column 4 are adjustable, when the cutting task changes, only the positions of the transversely sliding grid main beam 2 and the independently sliding support column 4 need to be readjusted to adapt to new plate sizes and cutting paths, demonstrating good versatility and ease of maintenance. Overall, this embodiment can reduce direct laser burning of the support structure while ensuring stable load-bearing of the plate, improve the cutting quality of the bottom surface of the plate, reduce wear and tear on the support platform, and enhance the adaptability of the laser cutting equipment to different plates and layout methods.
[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
