Description

Technical Field

[0001] This invention relates to the field of laser processing equipment, and in particular to a floor slab cutting device, production line, and floor slab processing method. Background Technology

[0002] Prefabricated floor slabs are core prefabricated components in the field of industrialized building construction. Mass production and standardized manufacturing place stringent requirements on the precision of slab contour cutting and processing efficiency. The consistency of the cut contours on both sides of the slab directly determines the quality of subsequent assembly and welding. Traditional processing methods rely on robots combined with positioners for step-by-step cutting, which involves many process steps and makes it difficult to control positioning errors. This can easily lead to dimensional deviations in the slabs, restricting the processing stability and capacity of the entire prefabricated floor slab production line.

[0003] The current mainstream cutting and processing solution for prefabricated floor slabs adopts a horizontal single-sided cutting structure. The workpiece is first laid flat for single-sided cutting, then the panel is flipped with the help of a positioner, and the robot is repositioned to perform reverse cutting. The equipment relies on manual visual teaching to determine the cutting trajectory. Each robot is equipped with only one cutting head and can only complete the processing of one side of the panel at a time. The entire cutting process consists of multiple steps, including loading, single-sided cutting, flipping and secondary positioning, reverse cutting, and unloading. This is a cutting process commonly used in prefabricated floor slab processing workshops.

[0004] The step-by-step flip-cutting mode has several production shortcomings: the two positioning of the sheet material is prone to contour deviation, making it difficult to control the gap in subsequent assembly and welding, and resulting in poor consistency of workpiece dimensions; manual teaching and positioning relies on visual judgment, resulting in large positioning errors, and teaching programming is time-consuming; single-head and single-sided cutting is slow, equipment capacity is limited, and the simultaneous arrangement of multiple cutting machines will significantly increase the workshop floor area, and the equipment procurement and maintenance costs are high, making it unsuitable for the large-volume, high-precision continuous production needs of large-size prefabricated floor slabs. Summary of the Invention

[0005] This invention addresses the problem that current floor slab processing requires flipping with a positioner, processing on both sides separately, repeated positioning, and long processing time by providing a floor slab cutting device.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: a floor slab cutting device, including a frame, the frame including a workpiece support part and two laser module support parts, the two laser module support parts being located on both sides of the workpiece support part; the workpiece support part includes a base frame and a top frame, the base frame is arranged along a first direction, the top of the base frame is provided with a plurality of first material support rollers along the first direction, the top frame is arranged along the first direction and located directly above the base frame, the bottom surface of the top frame is provided with a plurality of pressure rollers along the first direction, and the base frame and / or the top frame are also provided with a plurality of first support rollers on both sides respectively, the first support rollers being movable between the first material support rollers and the pressure rollers in the vertical direction; the laser module support part includes a vertical frame, and laser head modules are respectively mounted on the two vertical frames through a shaft movement system, the processing directions of the laser head modules on both sides being arranged opposite to each other. The workpiece is vertically clamped and conveyed, and the laser head modules on both sides simultaneously cut the plate on both sides. The front and back contours can be processed in one positioning, eliminating the dimensional deviation caused by the traditional flipping and secondary positioning, and ensuring uniform gaps in subsequent assembly and welding. The material support roller, pressure roller and liftable first support roller work together to limit the long floor plate at the top and bottom and on both sides, preventing the plate from tipping over and shaking during cutting, and improving the cutting accuracy.

[0007] Preferably, multiple first linear modules are installed on the top frame along a first direction. The first linear modules are vertically arranged, and each first linear module includes a central linear unit and two side linear units. The two side linear units are located on either side of the central linear unit. The movable part of the central linear unit is located at the bottom and is equipped with a top beam. The bottom surface of the top beam is open, and the pressure roller is installed in the top beam, with its lower part located outside the bottom surface of the top beam. The movable part of the side linear units is equipped with a lower extension bracket, and two lower extension brackets are located on either side of the top beam. The first support roller is installed at the lower end of the lower extension bracket and can move to below the top beam. The split-type linear module allows independent adjustment of the height of the pressure roller and the first support roller, adapting to different specifications of floor slabs. The pressure roller presses from above, and the two side first support rollers provide lateral support, clamping and constraining the sheet material at multiple points, preventing warping or displacement of the sheet material during cutting and conveying.

[0008] Preferably, two horizontal beams are installed on the side facade of the upright facing the base frame. The two horizontal beams are arranged parallel vertically and extend along a first straight line. On each upright, a vertical beam is provided on both horizontal beams, and the upper and lower ends of the vertical beam are respectively movably mounted on the two horizontal beams. The laser head module is movably mounted on the vertical beam. The horizontal beams and vertical beams form a three-axis Cartesian motion frame. The three-axis motion trajectory control logic is mature, easy to debug, and adaptable to various floor slab contour cutting programs.

[0009] Preferably, the crossbeam is provided with a guide rail and a rack, the end of the vertical beam is slidably mounted on the guide rail, and the end of the vertical beam is also provided with a drive motor. A drive gear is mounted on the output shaft of the drive motor, and the drive gear meshes with the rack. The gear and rack transmission combined with the linear guide rail provides high transmission rigidity, smooth operation, and high displacement adjustment accuracy.

[0010] Preferably, both uprights have protective sheet metal on their opposite sides. The protective sheet metal isolates laser radiation and metal dust, reducing equipment safety hazards, while also preventing debris from entering the transmission mechanism, reducing wear on guide rails and racks, and extending equipment maintenance cycles.

[0011] On the other hand, the present invention also provides a floor slab cutting production line, employing the aforementioned floor slab cutting equipment, and further including a feeding device and a discharging device, located at opposite ends of the floor slab cutting equipment along a first straight line direction; the feeding device includes a side support frame and a bracket, the bracket being located on the lower side of the side support frame, and the bracket having multiple second material-supporting rollers arranged along the first straight line direction, with the positions of the second material-supporting rollers collinear with and continuously connected to the positions of the first material-supporting rollers in the first straight line direction; a second straight module is provided on the top side of the side support frame, the second straight module being arranged vertically, a side extension bracket being provided on the moving part of the second straight module, and a second support roller being provided at the bottom of the side extension bracket, the second support roller being located on the same side of the side support frame as the bracket; the feeding device and the discharging device have the same structure. The feeding and discharging devices are symmetrically arranged, the roller conveyor is fully continuous, and the sheet material is conveyed without jamming; the second straight module drives the second support roller to rise and fall, providing lateral support to the sheet material during the feeding flipping and discharging flattening stages, preventing long sheets from bending and deforming, resulting in a compact production line layout.

[0012] Preferably, a plurality of third support rollers are also fixedly provided on the side of the side support frame. The third support rollers are located on the same side of the side support frame as the second support rollers, and the third support rollers are located between the second support rollers and the side support frame. The third support rollers and the second support rollers form a multi-layer lateral support, which lengthens the stress support range of the plate and greatly improves the structural stability when the large-size floor slab is flipped and erected, preventing the plate from tilting to the side.

[0013] Preferably, the loading and unloading devices further include a flipping mechanism, which is disposed on one side of the bracket. The flipping mechanism includes multiple third material-supporting rollers and a flipping frame, with the flipping frame located within the interval between adjacent third material-supporting rollers. The flipping frame can flip towards the side support frame. The flipping frame is embedded in the gap between the material-supporting rollers, without occupying additional conveying space, and can quickly flip flat floor slabs into a vertical processing posture. During unloading, it is reversed and laid flat, achieving automated flow.

[0014] Preferably, a tilting drive cylinder is connected below the tilting frame. The tilting drive cylinder is a telescopic cylinder. The cylinder body of the tilting drive cylinder is hinged to the installation base of the production line, and the cylinder rod of the tilting drive cylinder is hinged to the bottom surface of the tilting frame. The cylinder hinged drive structure is low in cost, responds quickly, has a stable and controllable tilting angle, is simple in structure and easy to maintain, and is suitable for continuous high-intensity operation conditions in the workshop.

[0015] Thirdly, the present invention also provides a method for processing floor slabs, comprising the following steps: S1. The floor slab to be processed is conveyed to the flipping mechanism of the feeding device. The flipping mechanism of the feeding device flips the floor slab to a vertical position. The second straight module and the first straight module are adjusted according to the vertical dimensions of the floor slab so that the second support roller and the first support roller are located within the width of the floor slab. S2. The feeding device transports the floor slab to the floor slab cutting equipment, and the laser head modules on both sides process both sides of the floor slab simultaneously; S3. The processed floor slab is conveyed to the unloading device. The second linear module of the unloading device rises, and then the flipping mechanism restores the floor slab to a flat position.

[0016] The entire process involves single-positioning and simultaneous double-sided cutting, eliminating the need for flipping and secondary positioning, thus significantly improving processing efficiency. The fully automated roller conveyor and automatic flipping eliminate the need for manual intervention, resulting in high consistency of the cutting contour and effectively reducing the difficulty of subsequent assembly and welding. This technology is suitable for the large-scale continuous production of prefabricated floor slabs.

[0017] As can be seen from the above technical solutions, the beneficial effects of this invention are as follows: This floor slab cutting equipment vertically clamps the workpiece, and the laser head modules on both sides simultaneously perform double-sided cutting. One-time positioning eliminates the dimensional deviations caused by traditional flipping and secondary positioning, ensuring the accuracy of subsequent assembly and welding. The base frame material support roller and top frame pressure roller, combined with the liftable first support roller, achieve multi-point vertical and lateral positioning of the plate. The separate first linear module allows for independent adjustment of the support height, adapting to different specifications of floor slabs and effectively preventing warping, swaying, and tipping of the plate during the cutting process. The horizontal and vertical beams on the upright frame form a three-axis Cartesian motion frame, relying on the guide rail rack and drive motor to achieve high-precision and stable transmission, simplifying motion control. Easy to debug, the outer protective sheet metal of the upright frame blocks laser-induced dust splashes, protecting transmission components and reducing safety risks; the matching production line has symmetrical loading and unloading devices with consistent structures at both ends, and the roller conveyor can be used for smooth conveying without jamming. The second linear module drives the second support roller to cooperate with the fixed third support roller to form multi-layer lateral support, improving the stability of large-size floor slabs when flipped and erected. The embedded flipping frame is driven by a cylinder to complete the automatic flipping and transformation of the board, without occupying extra space and with a simple structure that is easy to maintain; the matching processing method is fully automated in conveying and flipping, eliminating the need for secondary positioning processes, significantly improving processing efficiency, and ensuring good consistency of the board cutting contour, making it suitable for the large-scale continuous production of prefabricated floor slabs.

Detailed Implementation

[0028] To make the objectives, features, and advantages of this patent more apparent and understandable, the technical solutions of this patent will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this patent, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] Example 1 like Figures 1 to 7 As shown, a floor slab cutting device includes a frame 00, which is divided into a workpiece support section and two sets of laser module support sections. The two sets of laser module support sections are symmetrically arranged on the left and right sides of the workpiece support section. The workpiece support section is composed of a base frame 1 and a top frame 2. The base frame 1 is laid out as a whole along a first conveying direction. Multiple first material support rollers 3 are equidistantly mounted on the top surface of the base frame 1. The first material support rollers 3 are rotatably installed through bearing seats to support the bottom of the floor slab. The top frame 2 is erected parallel to the base frame 1 directly above it. Multiple pressure rollers 4 are arranged along the first direction on the lower surface of the top frame 2. The pressure rollers 4 extend downward to press the upper surface of the floor slab. Multiple first support rollers 5 are installed on both sides of the base frame and both sides of the top frame. The first support rollers 5 can be raised and lowered in the vertical direction and moved between the first material support rollers 3 and the pressure rollers 4 to achieve lateral limiting of the plate. The multi-point clamping at the top and bottom and the sides can firmly constrain the plate, and there is no warping or shaking during the cutting process, resulting in higher positioning accuracy. The laser module support is provided with a stand 6. Each of the two stands 6 is equipped with a complete axial motion system and a laser head module 7. The cutting working surfaces of the laser head modules 7 on the left and right sides face each other, which can simultaneously perform laser processing on both sides of the floor slab. The double-sided cutting is completed in one positioning, eliminating the traditional flipping and secondary positioning process, preventing the dimensional deviation caused by two positioning, and ensuring uniform gaps in subsequent assembly and welding.

[0030] The top frame 2 is fixed with multiple vertically installed first linear modules 8 along the first conveying direction. Each first linear module 8 includes a middle linear unit 8-1 and two side linear units 8-2. The two side linear units 8-2 are symmetrically arranged on both sides of the middle linear unit 8-1. The lower moving part of the middle linear unit 8-1 is rigidly connected to the top beam 9. The bottom of the top beam 9 is hollow and open. The pressure roller 4 is assembled inside the top beam 9 through a rotating shaft. The lower end of the pressure roller 4 passes through the bottom surface of the top beam 9 and contacts the plate. The lower moving part of the side linear unit 8-2 is fixed with a lower extension bracket 10. The two lower extension brackets 10 are arranged on the left and right sides of the top beam 9. The first support roller 5 is rotatably assembled at the bottom of the lower extension bracket 10 and rises and falls with the side linear unit 8-2 to the bottom of the top beam 9 to achieve lateral support. The split linear module can independently adjust the height of the pressure roller and the support roller to adapt to different length and width specifications of floor slabs. The upright frame 6 has two horizontal beams 11 fixed parallel to the vertical surface of the base frame 1. The two horizontal beams 11 extend along a first direction. A vertical beam 12 is slidably mounted between the two horizontal beams 11 of a single upright frame 6. The upper and lower ends of the vertical beam 12 are respectively engaged with the surface of the horizontal beam 11. The laser head module 7 is vertically slidably assembled along the vertical beam 12. The horizontal beams and vertical beams form a three-axis Cartesian motion frame. The control logic is mature, no manual teaching is required, the error of manual visual point measurement is avoided, and programming and debugging are simple.

[0031] The top surface of the crossbeam 11 is synchronously covered with guide rails 15 and racks 16. The sliding seats at both ends of the vertical beam 12 are attached to the guide rails 15 to achieve horizontal guidance. The end of the vertical beam 12 is fixed with a drive motor 17. The output shaft of the drive motor 17 is equipped with a drive gear. The drive gear meshes with the rack 16. The vertical beam 12 is driven to move as a whole by the gear and rack transmission. The transmission is rigid, the operation is stable, the displacement adjustment accuracy is high, and the numerical adjustment of the processing offset is convenient. The outer walls of the uprights 6 on both sides, away from the base frame 1, are fully covered with protective sheet metal 13. The protective sheet metal 13 is fixed by bolts to isolate the sparks and dust generated by laser cutting and reduce equipment safety hazards.

[0032] Example 2 This embodiment further provides a floor slab cutting production line, equipped with the floor slab cutting equipment described in Embodiment 1, such as... Figure 1 , 2 As shown, along the first linear conveying direction, the floor slab cutting equipment is equipped with a feeding device 01 and a discharging device 02 at both ends. The feeding device 01 and the discharging device 02 have the same overall structure and are symmetrically arranged to facilitate production line layout planning; Figure 8As shown, the feeding device 01 is equipped with a side support frame 18. A bracket 19 is fixed on one side of the lower part of the side support frame 18. Multiple second material support rollers 20 are equidistantly mounted inside the bracket 19 along a first straight line direction. The second material support rollers 20 are collinear with the first material support roller 3 in Embodiment 1 and their ends are connected end to end, realizing continuous conveying of the floor slab without gaps and ensuring that the roller conveyor is unobstructed throughout the entire line. A second straight module 21 is vertically installed on one side of the top of the side support frame 18. The sliding part of the second straight module 21 is rigidly fixed to the side extension bracket 22. A second support roller 23 is rotatably mounted at the bottom of the side extension bracket 22. The second support roller 23 and the bracket 19 are on the same side of the side support frame 18. During the lifting process, it provides lateral support to the vertically placed floor slab, preventing bending and deformation when long-sized plates are flipped and placed upright.

[0033] Multiple sets of third support rollers 24 are fixed between the side wall of the side support frame 18, the second support roller 23, and the side support frame 18. The third support rollers 24 and the second support rollers 23 are arranged in the same direction, and the two work together to form a multi-level lateral support structure, which lengthens the stress support range of the plate and greatly improves the overall stability of the large-size floor slab after it is erected, effectively preventing the plate from tilting to the side. A flipping mechanism is provided on one side of the bracket 19. The flipping mechanism consists of multiple third material support rollers 25 and a flipping frame 26. The flipping frame 26 is housed in the gap between the adjacent third material support rollers 25, without occupying additional conveying channel space. The flipping frame 26 can flip unidirectionally toward the side support frame 18, thereby completing the automatic switching between the flat and vertical postures of the floor slab, saving the manual flipping and handling process.

[0034] The tilting frame 26 is hinged to the bottom surface of the tilting drive cylinder 14. The tilting drive cylinder 14 adopts a standard telescopic cylinder structure. The lower end of the cylinder body of the tilting drive cylinder 14 is hinged and fixed to the production line ground installation foundation. The top end of the telescopic cylinder rod of the tilting drive cylinder 14 is hinged to the lower surface of the tilting frame 26. The tilting frame 26 is stably tilted by the telescopic push and pull of the cylinder. The cylinder drive structure is low in cost, responds quickly, and the tilting angle is stable and controllable. The structure is simple and easy to maintain, and it is suitable for long-term continuous operation in the workshop. The roller conveyor of the entire loading and unloading device is connected to the internal roller conveyor of the floor slab cutting equipment. With the cooperation of the lateral support rollers for positioning, the overall production line occupies less space. It can realize the matching of two cotton filling machines with a single cutting machine, reducing equipment investment and site costs, and is suitable for flexible production of floor slabs with different output and specifications.

[0035] Example 3 This embodiment further provides a floor slab processing method, including the following steps: S1. The floor slab to be processed is fed into the loading device 01 through the front-end conveying mechanism and placed above the third material support roller 25. The floor slab is laid flat and supported on the surface of the third material support roller 25. The flipping drive cylinder 14 extends and pushes the flipping frame 26 to flip towards the side support frame 18, raising and flipping the floor slab to a vertical position. According to the current vertical height of the floor slab, the lifting stroke of the second linear module 21 of the loading device 01 and the first linear module 8 inside the floor slab cutting equipment are adjusted respectively, so that the second support roller 23, the third support roller 24, and the first support roller 5 are all in contact with the floor slab surface area, completing the multi-directional lateral limiting support of the board material, avoiding the problem of board tipping and bending throughout the process, and adapting to various prefabricated floor slabs with a length of 11-13m and a width of 2-3m.

[0036] S2. The second material support roller 20 rotates synchronously, continuously conveying the vertical floor slab along the first straight line to the workpiece support area inside the frame 00. The first material support roller 3 on the base frame 1 supports the bottom of the floor slab, and the pressure roller 4 below the top frame 2 presses down to tighten the upper part of the floor slab. The first support rollers 5 on both sides lift and position the slab laterally, ensuring that the plate is constrained in all directions without displacement deviation. The laser head module 7 on the two uprights 6 starts synchronously and moves synchronously along the three-axis trajectory formed by the horizontal beam 11 and the vertical beam 12, completing the contour laser cutting from both sides of the floor slab simultaneously. One-time positioning and double-sided synchronous forming eliminates multiple processes such as flipping, secondary positioning, and re-correction, greatly improving processing efficiency. The double-sided cut contours are completely consistent, effectively simplifying the subsequent assembly and welding process and reducing the difficulty of controlling the welding gap.

[0037] S3. The cut floor slabs are continuously conveyed to the unloading device 02 via roller conveyor. The second linear module 21 of the unloading device 02 is raised, releasing the lateral constraint of the second support roller 23 on the floor slab. The unloading device 02 is equipped with a flipping drive cylinder 14 that retracts, pulling the flipping frame 26 to rotate in the opposite direction, lowering the vertical floor slab back to its flat position, and then sending it out of the production line by the second material support roller 20 of the unloading device 02. The whole process is automated and requires no manual intervention. The cutting dimensions are highly consistent and can meet the needs of large-scale continuous processing and production of prefabricated floor slabs.

[0038] As can be seen from the above embodiments, the advantages of the present invention are as follows: The floor slab cutting equipment, production line, and processing method of this solution vertically clamp the floor slab and then simultaneously cut it on both sides with double-sided laser head modules, achieving one-time positioning and forming, eliminating the dimensional deviation caused by the traditional flipping and secondary positioning, and ensuring the accuracy of subsequent welding; the first material support roller of the base frame and the pressure roller of the top frame, together with the liftable first support roller, form multi-point limiting in the upper, lower, and lateral directions; the first linear module can independently adjust the support height to adapt to various specifications of plates, effectively suppressing the warping and shaking of the plates during cutting; the horizontal beam and vertical beam of the upright frame form a three-axis motion frame, relying on the guide rail rack and drive motor to achieve high-precision and stable transmission; the outer side of the upright frame is protected against... The sheet metal shielding system blocks laser sparks and dust, protecting transmission components and improving operational safety. Symmetrical loading and unloading devices with identical structures are arranged at both ends of the production line, and seamless roller conveyor connections ensure smooth transport. The second and third support rollers form multi-layered lateral support, enhancing the stability of large-size floor slabs. An embedded flipping frame, driven by a hinged telescopic cylinder, automatically switches between flat and vertical positions of the sheet metal, resulting in a compact and easy-to-maintain structure. The entire processing is fully automated, eliminating the need for a secondary flipping and positioning process, significantly improving processing efficiency and ensuring high consistency in cutting contours. It is suitable for large-scale continuous production of prefabricated floor slabs, while reducing overall equipment footprint and lowering production line maintenance costs.
