Description

Technical Field

[0001] This invention relates to the field of sheet metal cutting equipment, and in particular to a non-destructive intelligent sheet metal cutting workstation and its control method. Background Technology

[0002] With the rapid development of the customized furniture, interior decoration, and high-end panel furniture industries, the market has increasingly stringent requirements for the processing precision, production efficiency, and surface quality of finished products of panel processing equipment. Currently, the panel cutting and processing field mainly adopts two equipment layout modes, but both have varying degrees of structural defects.

[0003] The first type is the traditional discrete multi-machine independent layout mode; the existing conventional solution uses multiple independent devices to operate in stages, that is, setting up independent material storage and feeding machines, automatic labeling machines, CNC cutting machines, and material conveying equipment, and connecting each device through manual or auxiliary conveying devices. This mode has the following structural problems: Firstly, each piece of equipment has an independent foundation and installation reference, and the relative positional accuracy between the equipment depends solely on on-site installation and adjustment. After long-term operation, differences in foundation settlement of each independent base and equipment vibration displacement will cause changes in the positional relationship between workstations, increasing the cumulative positioning error and affecting the final cutting size accuracy and labeling position accuracy.

[0004] Secondly, forklift access and operating space need to be reserved between each piece of equipment, resulting in a large workshop area. At the same time, large-capacity material handling machines usually require deep pits below ground to accommodate hydraulic lifting mechanisms in order to achieve multi-layer stacking of sheet materials, leading to high civil engineering costs and difficult maintenance.

[0005] Third, the feeding equipment often uses mechanical grippers or side pushers to directly contact the edges or surfaces of the boards, which can easily cause chipping or scratches on the edges and corners of high-value-added boards such as high-gloss boards and UV boards.

[0006] The second type is the integrated long-stroke gantry crane mode. To address the accuracy and space constraints of independent multi-machine layouts, an integrated solution has emerged in recent years, where each workstation is arranged in a straight line along the same long bed, and a large gantry crane straddles the entire line. In this solution, the gantry crane spans from the beginning to the end of the bed, responsible for sequentially transferring the sheet metal from the storage area to the labeling, cutting, and unloading stations. However, this mode has revealed new structural defects in practice: Firstly, the gantry frame needs to cover the entire length of the line, resulting in a large span and long beams. To ensure rigidity, the amount of steel used and the structural dimensions must be increased significantly, leading to a significant increase in equipment manufacturing costs and overall machine weight.

[0007] Secondly, a single gantry crane needs to complete multiple actions in sequence, such as picking up materials, feeding materials, waiting for processing, and picking up materials again. A serial waiting relationship is formed between each workstation, and the production cycle is limited by the reciprocating stroke of the gantry crane, thus limiting the improvement of efficiency.

[0008] Third, during high-speed reciprocating motion, long-stroke gantry cranes are prone to torsional deformation due to uneven stress on both ends of the crossbeam. After long-term operation, the linear guide rails wear unevenly, affecting the transfer and positioning accuracy.

[0009] Fourth, the storage area still needs to be set at the beginning of the bed. Since the gantry straddles the bed, the plates in the storage area can only be put in from the side or end of the bed, making it impossible for the forklift to enter directly from the front to load the whole stack, which makes the material changing operation inconvenient.

[0010] In both of the aforementioned modes, the transfer of sheet metal between the labeling and cutting stations, and between the cutting and unloading stations, is typically accomplished by the same gantry crane or a separate conveyor. Existing solutions lack structured positioning and buffering mechanisms at the intersections of each station, making it prone to sheet metal collisions with station edges due to positional deviations during transfer, resulting in sheet metal breakage or equipment damage. Furthermore, it is difficult to maintain a consistent workbench height across stations, requiring multiple lifting and lowering of the sheet metal during cross-station transfers, increasing the risk of scratching against conveyor rollers or transition plates.

[0011] Furthermore, existing equipment is equipped with independent control cabinets and operation panels, and the individual machines are only cascaded through simple start / stop signal lines, failing to form a unified hardware input / output architecture. When a workstation experiences material shortages, plate jams, or vacuum leaks, other workstations cannot promptly obtain fault status, resulting in plate accumulation or equipment idling, and poor overall collaborative work capability.

[0012] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention

[0013] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a non-destructive intelligent board cutting workstation and its control method. By sharing a basic bed, bed side guide rails, side waiting area, and segmented shuttle transfer method, it achieves large-capacity storage without pit digging, non-destructive processing with zero scratches throughout the process, and high space utilization.

[0014] To achieve the above objectives, the present invention adopts the following technical solution: A non-destructive intelligent board cutting workstation includes: The shared basic bed has a worktable area extending along the X-axis and bed side guide rails located on both sides of the worktable area. The worktable area is arranged in sequence along the X-axis as an automatic labeling area, a CNC cutting area, and a material unloading area. A waiting area is reserved on the side of the shared basic bed corresponding to the automatic labeling area. A gantry-type non-destructive feeding machine straddles the automatic labeling area and the waiting area of ​​the shared base bed to transfer the boards from the waiting area to the automatic labeling area. An automatic labeling and material transfer machine is set above the shared base bed and can move back and forth between the automatic labeling area and the CNC cutting area along the side guide rail of the bed; A CNC cutting and pushing machine is set above the shared base bed and can move back and forth between the CNC cutting area and the discharge area along the side guide rail of the bed; The controller is located on the side of the shared base bed and is connected to the gantry-type non-destructive feeding machine, the automatic labeling and transferring machine, and the CNC cutting and pushing machine.

[0015] As a preferred embodiment, the gantry-type non-destructive feeding machine includes a rigid gantry and an X-axis crossbeam, a first Y-axis moving mechanism, and a first Z-axis lifting mechanism mounted on the rigid gantry. The first Y-axis moving mechanism drives the X-axis crossbeam to move relative to the rigid gantry along the Y-axis. The first Z-axis lifting mechanism is mounted on the X-axis crossbeam, and multiple independently controlled vacuum suction cups are suspended at the bottom of the first Z-axis lifting mechanism. The lifting of the vacuum suction cups is controlled by the first Z-axis lifting mechanism. The multiple independently controlled vacuum suction cups can be used in appropriate areas according to the size of the sheet material, avoiding suction failure on small sheets or uneven force on the edges of large sheets, thus preventing indentations. Compared to mechanical grippers, the vacuum suction method does not contact the edges and surfaces of the sheet material throughout the process, avoiding chipping and scratches.

[0016] As a preferred embodiment, the automatic labeling and transferring machine includes a gantry-type labeling bracket, an X-axis moving mechanism, an automatic labeling mechanism, a second Z-axis lifting mechanism, and a transfer suction cup assembly. The X-axis moving mechanism drives the gantry-type labeling bracket to translate along the guide rail on the side of the bed. The automatic labeling mechanism and the second Z-axis lifting mechanism are mounted on the labeling beam of the gantry-type labeling bracket. The automatic labeling mechanism is also connected to a second Y-axis moving mechanism to drive the automatic labeling mechanism to move along the Y-axis of the labeling beam. The transfer suction cup assembly is connected to the bottom of the second Z-axis lifting mechanism. The automatic labeling mechanism and the transfer suction cup assembly do not interfere with each other and share the same travel drive system, reducing the number of independent drive components and lowering equipment manufacturing costs and control complexity.

[0017] As a preferred embodiment, the upper surface of the automatic labeling area is provided with vacuum suction holes, and multiple automatic positioning blocks are provided at its ends. These automatic positioning blocks are driven by cylinders to extend upwards from the upper surface of the automatic labeling area to block the end of the board, or retract downwards to release the blockage. The automatic positioning blocks, driven by cylinders to extend upwards from the upper surface of the automatic labeling area, form a mechanical stop on the end of the board, achieving secondary alignment of the board before labeling. After labeling, the blocks retract downwards to release the blockage, allowing the transfer suction cup assembly to smoothly remove the board. This telescopic block structure ensures that the board's position is fixed during labeling, eliminating labeling position deviations caused by conveying inertia or positioning errors, while not affecting the smoothness of subsequent transfer operations. The vacuum suction holes adhere and fix the board to the table surface during labeling, further ensuring the accuracy of the labeling position.

[0018] As a preferred embodiment, the rigid gantry straddles the automatic labeling area of ​​the shared base bed, with one side leg of the rigid gantry maintaining a distance from the shared base bed to naturally form a ground-level material storage waiting area. This eliminates the need for the waiting area to occupy additional length of the bed along the X-axis, instead utilizing the unused space on the side of the bed, achieving a compact layout of the entire line along the X-axis, shortening the overall equipment length, and saving workshop floor space.

[0019] As a preferred embodiment, the upper surface of the CNC cutting area is a vacuum adsorption processing table. The CNC cutting and pushing machine includes a cutting gantry, a three-axis linkage motion system, and a processing spindle. The three-axis linkage motion system includes a cutting X-axis moving mechanism, a cutting Y-axis moving mechanism, and a cutting Z-axis moving mechanism. The cutting X-axis moving mechanism drives the cutting gantry to move along the bed side guide rail of the shared base bed. The cutting Y-axis moving mechanism drives the cutting Z-axis moving mechanism and the processing spindle to move along the Y-axis of the cutting beam of the cutting gantry. The processing spindle is connected to the cutting Z-axis moving mechanism, which drives the processing spindle to move up and down. The three-axis linkage motion system drives the processing spindle to move in the X, Y, and Z directions, and works with the vacuum adsorption processing table to adsorb and fix the plate, achieving high-precision cutting. The cutting X-axis moving mechanism and the automatic labeling and transferring machine share the same set of bed side guide rails, ensuring that the two transfer mechanisms have the same motion reference in the X-axis direction, eliminating the cumulative position error caused by the independent installation of the labeling machine and the cutting machine in the traditional solution.

[0020] As a preferred embodiment, the discharge area is equipped with a discharge belt conveyor located at the end of the shared base bed. This conveyor receives the finished sheet metal and waste material pushed by the CNC cutting and pushing machine and transports them outside the equipment. This discharge belt conveyor enables the automatic discharge of finished products and waste material after cutting, eliminating the need for manual intervention, reducing the labor intensity of operators, and shortening the processing cycle of a single sheet metal.

[0021] As a preferred embodiment, the shared base bed is a box-shaped steel structure welded from high-strength steel plates, possessing extremely high torsional and bending stiffness. The high-strength steel plates, after stress-relief annealing, do not deform during long-term operation. This structure serves as the common installation benchmark for the automatic labeling area, CNC cutting area, unloading area, and the bed's side guide rails, ensuring the long-term stability of the relative positional accuracy between each workstation and between the motion guide rails of each transfer mechanism. This forms the physical basis for achieving high-precision machining across the entire line.

[0022] As a preferred embodiment, multiple transfer suction cup assemblies are provided and mounted on a transfer rack. The transfer rack and the transfer suction cup assemblies are staggered from the automatic labeling and transfer machine. The transfer rack extends along the X-axis to both sides of the labeling beam of the gantry-type labeling bracket. The transfer suction cup assemblies are distributed at least on both sides of the transfer rack extending from the labeling beam of the gantry-type labeling bracket, thereby expanding the total gripping area and lifting the entire sheet material upwards. This layout allows the transfer suction cup assemblies to simultaneously adsorb multiple stress points on large-sized sheets, preventing the sheet material from bending or deforming due to its own weight or causing indentations due to excessive local stress during transfer. Simultaneously, the staggered arrangement of the transfer rack and the labeling beam ensures that labeling operations and transfer adsorption do not interfere with each other, further enhancing the parallel operation capability within the workstation.

[0023] A control method for a non-destructive board intelligent cutting workstation as described in any of the preceding items includes the following steps: Step S1, feeding step: The gantry-type non-destructive feeding machine transfers the single sheet of board from the waiting area to the automatic labeling area, and positions the board in the automatic labeling area; Step S2, Labeling and Transfer Step: The automatic labeling and transfer machine performs labeling operations on the board material positioned in the automatic labeling area, and after labeling is completed, transfers the board material from the automatic labeling area to the CNC cutting area; Step S3, Cutting and Unloading Steps: The CNC cutting and pushing machine performs cutting processing on the board in the CNC cutting area. After processing, the CNC cutting and pushing machine pushes the finished product and waste from the CNC cutting area to the unloading area. In step S2, after the automatic labeling and transferring machine moves the sheet material to the CNC cutting area, it returns to the automatic labeling area to await the next sheet material. In step S1, the action of the gantry-type non-destructive feeding machine moving the next sheet material to the automatic labeling area is at least partially simultaneous with the action of the CNC cutting and pushing machine pushing the finished product and waste material to the discharge area in step S3. This achieves overlapping operations of the independent transfer mechanisms in time. Compared to the traditional control method where a single gantry machine completes all transfer actions serially, this method significantly shortens the processing cycle of a single sheet material and improves the overall output efficiency of the workstation.

[0024] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly integrates the automatic labeling area, CNC cutting area and unloading area into the same worktable area by using a shared base bed. Moreover, the gantry-type non-destructive feeding machine only straddles the automatic labeling area and the waiting area on the side, without needing to cover the entire line. Compared with the traditional long-stroke gantry straddling the entire line, this layout significantly shortens the span of the gantry and the length of the crossbeam, reduces the manufacturing cost of the gantry structure and the weight of the whole machine, and at the same time reduces the torsional deformation of the crossbeam during high-speed reciprocating motion, thus improving the transfer and positioning accuracy. The automatic labeling and transferring machine can move back and forth along the side guide rail of the bed between the automatic labeling area and the CNC cutting area. The CNC cutting and pushing machine can move back and forth along the same guide rail between the CNC cutting area and the discharge area. The two transfer mechanisms operate independently, achieving time overlap between the transfer of labeled boards to the cutting area and the pushing of finished products to the discharge area, breaking the cycle bottleneck of serial operation of a single gantry crane. In addition, the waiting area is located on the side of the shared base bed, naturally formed by the distance between one side of the gantry non-destructive loading machine's frame leg and the bed. This layout eliminates the need to set up the storage area at the beginning of the bed, allowing forklifts to directly load entire stacks from the side, realizing convenient and rapid stacking operations without the need to dig deep pits in the ground.

[0025] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0027] Please refer to Figures 1 to 8 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0028] In the description of this invention, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0029] A non-destructive board intelligent cutting workstation includes: a shared base bed 1, a gantry-type non-destructive feeding machine 2, an automatic labeling and transferring machine 3, a CNC cutting and pushing machine 4, and a controller 5.

[0030] In this embodiment, the shared base bed 1 is a box-shaped steel structure welded from high-strength steel plates. The box-shaped welded steel structure has extremely high resistance to torsion and deformation. The shared base bed 1 has a worktable area 101 extending along the X-axis and bed side guide rails 102 located on both sides of the worktable area. The worktable area 101 is arranged sequentially along the X-axis as an automatic labeling area 11, a CNC cutting area 12, and a discharge area 13. A waiting area 14 is reserved on the side of the shared base bed 1 corresponding to the automatic labeling area 11. The automatic labeling area 11 is the first processing section of the shared base bed 1. It is a flat and precise positioning platform. Vacuum adsorption holes are provided on its upper surface, and multiple automatic positioning blocks 111 are provided at its end. The automatic positioning blocks 111 are driven by cylinders to extend upwards to the upper surface of the automatic labeling area 11 to block the end of the plate, or to retract downwards to release the blockage on the plate. When the labeling board is placed on the upper surface of the automatic labeling area 11, the automatic labeling and transferring machine 3 moves the board towards the end. The extended automatic positioning block 111 stops and positions the board before labeling. The positioning block and the vacuum suction hole form a secondary alignment, ensuring the board is in an absolute reference position before labeling. The movable labeling head, in conjunction with the pressure rollers, allows for physical pressing of the designated position, solving the problem of label skewing and wrinkling caused by board misalignment in conveyor belt labeling methods.

[0031] The upper surface of the CNC cutting area 12 is a vacuum adsorption processing table. A vacuum chamber is installed inside the vacuum adsorption processing table, and the vacuum chamber is connected to a vacuum valve and a negative pressure generating device via pipelines. The vacuum negative pressure adsorption firmly fixes the material, preventing displacement during processing. The upper surface of the CNC cutting area 12 maintains the same horizontal reference as the upper surface of the automatic labeling area 11. Material arrival detection switches and anti-collision buffer mechanisms are installed between the automatic labeling area 11 and the CNC cutting area 12, and between the CNC cutting area 12 and the unloading area 13. The anti-collision buffer mechanism includes rubber buffer blocks and / or micro switches. This protects the hardware safety from cross-workpiece displacement. The arrival detection switch provides a position signal, and the rubber block and micro switch of the anti-collision buffer mechanism absorb energy and trigger an emergency stop hard signal before a mechanical collision occurs. This dual protection ensures the safety of the precision guide rail, lead screw, and the material itself, significantly improving the service life and reliability of the automated production line.

[0032] The discharge area 13 is equipped with a discharge belt conveyor 131, which is located at the end of the shared foundation bed 1 to realize material discharge.

[0033] The gantry-type non-destructive feeding machine 2 straddles the automatic labeling area 11 and the waiting area 14 of the shared base bed 1 to transfer the plates in the waiting area 14 to the automatic labeling area 11. The gantry-type non-destructive feeding machine 2 includes a rigid gantry 21 and an X-axis crossbeam 22, a first Y-axis moving mechanism 23, and a first Z-axis lifting mechanism 24 set on the rigid gantry 21. The rigid gantry 21 straddles the automatic labeling area 11 of the shared base bed 1, and one side of the rigid gantry 21 is spaced apart from the shared base bed 1 to naturally form a ground-type storage waiting area 14. The first Y-axis moving mechanism 23 drives the X-axis crossbeam 22 to move relative to the rigid gantry 21 along the Y-axis. The first Z-axis lifting mechanism 24 is set on the X-axis crossbeam 22. Multiple independently controlled vacuum suction cup groups 25 are suspended at the bottom of the first Z-axis lifting mechanism 24. The vacuum suction cup groups 25 are raised and lowered by the first Z-axis lifting mechanism 24. The corresponding vacuum suction cup group 25 can be automatically activated according to the size of the plate. For example, once the placement position of the board in the waiting area 14 and the board size are determined, the controller 5 will activate the corresponding vacuum suction cup group 25 according to the board size for the same batch of boards. In other embodiments, a photoelectric ranging array for detecting the board size can also be set on the gantry-type non-destructive feeding machine 2. The output end of the photoelectric ranging array is electrically connected to the control end of the vacuum solenoid valve of each vacuum suction cup group 25. Each vacuum suction cup group 25 is connected to an independent vacuum solenoid valve and a pressure sensor. The opening and closing of the vacuum solenoid valves of each zone can be directly controlled by the photoelectric ranging array through hardware. The suction cups can be activated adaptively according to the board size without relying on software logic. In addition, the pressure sensor can ensure the reliability of adsorption and avoid the risk of the board falling during the gripping process.

[0034] The automatic labeling and transferring machine 3 is mounted above the shared base bed 1 and can move back and forth along the side guide rail 102 between the automatic labeling area 11 and the CNC cutting area 12. The automatic labeling and transferring machine 3 includes a gantry-type labeling bracket 31, an X-axis moving mechanism 32, an automatic labeling mechanism 33, a second Z-axis lifting mechanism 34, and a transfer suction cup assembly 35. The X-axis moving mechanism 32 drives the gantry-type labeling bracket 31 to move along the side guide rail 102. The automatic labeling mechanism 33 and the second Z-axis lifting mechanism 34 are mounted on the labeling beam of the gantry-type labeling bracket 31. The automatic labeling mechanism 33 is also connected to a second Y-axis moving mechanism 36 to drive the automatic labeling mechanism 33 to move along the Y-axis of the labeling beam. The transfer suction cup assembly 35 is connected to the bottom of the second Z-axis lifting mechanism 34. The automatic labeling mechanism 33 typically includes a label peeler and a pressing roller. Multiple transfer suction cup assemblies 35 are provided and installed on a transfer frame 351. The transfer frame 351 and the transfer suction cup assemblies 35 are staggered from the automatic labeling and transfer machine 3. The transfer frame 351 extends along the X-axis to both sides of the labeling beam of the gantry-type labeling bracket 31. The transfer suction cup assemblies 35 are distributed at least on both sides of the area of ​​the transfer frame 351 extending from the labeling beam of the gantry-type labeling bracket 31 to expand the total gripping area and lift the entire board upward. Conventional cutting and labeling machines use a suction cup to pick up one end of the board and drag the other end of the board forward. During the dragging process, there will be friction with the table surface, which will scratch the surface of the board. In this embodiment, three sets of transfer suction cup assemblies 35 are provided, that is, three gripping suction cups are provided, which can pick up the entire board and place it into the CNC cutting area 12, avoiding scratches on the surface of the board and meeting the processing requirements of some special boards that do not allow any scratches or damage to the surface.

[0035] The CNC cutting and pushing machine 4 is mounted above the shared base bed 1 and can reciprocate along the side guide rail 102 between the CNC cutting area 12 and the unloading area 13. The CNC cutting and pushing machine 4 includes a cutting gantry 41, a three-axis linkage motion system, and a machining spindle 43. The three-axis linkage motion system includes a cutting X-axis moving mechanism, a cutting Y-axis moving mechanism, and a cutting Z-axis moving mechanism. The cutting X-axis moving mechanism drives the cutting gantry 41 to move along the side guide rail 102 of the shared base bed 1. The cutting Y-axis moving mechanism drives the cutting Z-axis moving mechanism and the machining spindle 43 to move along the Y-axis of the cutting beam of the cutting gantry 41. The machining spindle 43 is connected to the cutting Z-axis moving mechanism, which drives the machining spindle to move up and down. This ensures that the machining spindle performs high-precision, high-speed cutting in the X, Y, and Z directions. A 9kW high-speed electric spindle can be used. Typically, CNC cutting and feeding machines are also equipped with a dust removal system. The dust collection hood of the dust removal system is fixed on the housing of the high-speed electric spindle, and the dust collection hood is connected to an external dust collector through a hose, which effectively protects the spindle and the cutting tool and extends their service life.

[0036] The controller 5 is located beside the shared base bed 1 and is connected to the gantry-type non-destructive feeding machine 2, the automatic labeling and transferring machine 3, and the CNC cutting and pushing machine 4. The controller 5, also known as the central control system, is integrated in an electrical cabinet and includes a programmable logic controller (PLC), an industrial touch screen electrically connected to the PLC, digital input modules, and digital output modules. The input terminals of the digital input modules are connected to photoelectric sensors, pressure sensors, and position detection switches at each workstation. The output terminals of the digital output modules are connected to the drive motor of the gantry-type non-destructive feeding machine, each vacuum solenoid valve, vacuum valve, and the start relay of the dust removal system.

[0037] And, combined Figure 8 As shown, a control method for a non-destructive board intelligent cutting workstation as described above is provided, including the following steps: Step S1, feeding step: The gantry-type non-destructive feeding machine transfers the single sheet of board from the waiting area to the automatic labeling area, and positions the board in the automatic labeling area; Step S2, Labeling and Transfer Step: The automatic labeling and transfer machine performs labeling operations on the board material positioned in the automatic labeling area, and after labeling is completed, transfers the board material from the automatic labeling area to the CNC cutting area; Step S3, Cutting and Unloading Steps: The CNC cutting and pushing machine performs cutting processing on the board in the CNC cutting area. After processing, the CNC cutting and pushing machine pushes the finished product and waste from the CNC cutting area to the unloading area. In step S2, after the automatic labeling and transferring machine moves the sheet material to the CNC cutting area, it returns to the automatic labeling area to await the next sheet material. In step S1, the action of the gantry-type non-destructive feeding machine moving the next sheet material to the automatic labeling area is at least partially simultaneous with the action of the CNC cutting and pushing machine pushing the finished product and waste material to the discharge area in step S3. This achieves overlapping operations of the independent transfer mechanisms in time. Compared to the traditional control method where a single gantry machine completes all transfer actions serially, this method significantly shortens the processing cycle of a single sheet material and improves the overall output efficiency of the workstation.

[0038] Next, combined Figures 1 to 7 The structure of the intelligent non-destructive board cutting workstation shown is as follows: Figure 8 The control method flow shown details the workflow of the non-destructive board intelligent cutting workstation in this embodiment: I. Material Storage and Feeding Stage The operator uses a forklift to place a whole stack of boards (e.g., engineered wood panels with dimensions of 2800×1220×18mm) directly into the waiting area 14 from the side. The waiting area 14 is naturally formed by the gap between one side of the rigid gantry 21 of the gantry non-destructive loading machine 2 and the shared base bed 1. The forklift does not need to enter from the end of the bed, nor does it need to rely on a deep pit or a special lifting mechanism.

[0039] Driven by the first Y-axis moving mechanism 23, the X-axis beam 22 of the gantry-type non-destructive feeding machine 2 moves along the Y-axis direction of the rigid gantry 21 to directly above the waiting area 14. The first Z-axis lifting mechanism 24 drives multiple sets of vacuum suction cups 25 suspended at its bottom to descend until the suction cups of the vacuum suction cups 25 contact the upper surface of the uppermost sheet material in the waiting area 14. Each vacuum suction cup set 25 generates negative pressure through an independent vacuum pipeline to adsorb the sheet material. After adsorption is completed, the first Z-axis lifting mechanism 24 lifts up, separating the single sheet material from the stack.

[0040] Subsequently, the first Y-axis moving mechanism 23 drives the X-axis beam 22 to move along the Y-axis direction to directly above the automatic labeling area 11. The first Z-axis lifting mechanism 24 descends again, placing the adsorbed board onto the upper surface of the automatic labeling area 11. The vacuum suction cup assembly 25 releases negative pressure, and the first Z-axis lifting mechanism 24 lifts, completing the loading of one board. When the board is placed on the upper surface of the automatic labeling area 11, multiple automatic positioning blocks 111 at the end of the automatic labeling area 11 are driven by cylinders to extend upwards onto the upper surface, forming a mechanical stop at the end of the board, thereby achieving secondary alignment of the board in the X-axis. The vacuum adsorption holes provided on the upper surface open, generating negative pressure to adsorb and fix the board to the table surface.

[0041] II. Labeling Stage The second Y-axis moving mechanism 36 drives the automatic labeling mechanism 33 to move along the Y-axis of the labeling beam of the gantry-type labeling bracket 31 to the designated labeling position on the board (such as the lower right corner of the board). The automatic labeling mechanism 33 peels off the label and presses it onto the surface of the board. Of course, depending on the labeling position, the XY direction displacement can be automatically controlled as needed to reach the desired labeling position. After labeling is completed, the automatic positioning stop 111 is driven by a cylinder to retract downwards to release the stop on the board. At the same time, the vacuum suction holes on the upper surface of the automatic labeling area 11 release the negative pressure, releasing the suction on the board.

[0042] III. Board Transplanting Stage The second Z-axis lifting mechanism 34 of the automatic labeling and transferring machine 3 descends, driving the transfer suction cup assembly 35 at its bottom to contact the upper surface of the labeled board. The transfer suction cup assembly 35 is mounted on the transfer frame 351, which extends along the X-axis to both sides of the labeling beam of the gantry-type labeling bracket 31. The transfer suction cup assembly 35 is distributed in the extended area, simultaneously adsorbing multiple pressure points of the board. After the transfer suction cup assembly 35 generates negative pressure to adsorb the board, the second Z-axis lifting mechanism 34 lifts, raising the entire board from the automatic labeling area 11 until the board is parallel to the horizontal plane. The X-axis moving mechanism 32 drives the gantry-type labeling bracket 31 to translate along the bed side guide rail 102 towards the CNC cutting area 12, transferring the adsorbed board above the vacuum adsorption processing table of the CNC cutting area 12. The second Z-axis lifting mechanism 34 descends, placing the board on the vacuum adsorption processing table. The material transfer suction cup assembly 35 releases negative pressure, and the second Z-axis lifting mechanism 34 lifts, completing the transfer of the board. During this process, the automatic labeling and material transfer machine 3 moves together with its automatic labeling mechanism 33 and material transfer suction cup assembly 35, but the material transfer frame 351 is staggered from the labeling beam to ensure that the labeling mechanism and the transfer suction do not interfere with each other.

[0043] IV. Material Cutting and Processing Stage After the board material arrives at the vacuum adsorption processing table in the CNC cutting area 12, the vacuum generator connected below the table is activated, generating negative pressure through the adsorption holes on the table to adsorb and fix the board material. Driven by the X-axis moving mechanism, the cutting gantry 41 of the CNC cutting and pushing machine 4 moves along the side guide rail 102 of the bed to the predetermined processing position. The Y-axis moving mechanism drives the processing spindle 43 to move along the Y-axis of the cutting beam of the cutting gantry 41, and the Z-axis moving mechanism drives the processing spindle 43 to descend to the processing height. The processing spindle (e.g., a 9kW high-speed electric spindle) rotates and performs cutting, grooving, or drilling operations on the board material according to a predetermined path. During processing, the dust removal system carried on the processing spindle works simultaneously, collecting and discharging the sawdust generated during cutting through the dust collection hood. After processing is completed, the processing spindle is raised, the vacuum adsorption table releases negative pressure, and the adsorption on the board material is released.

[0044] V. Discharge Stage Driven by the X-axis moving mechanism, the cutting gantry 41 of the CNC cutting and pushing machine 4 moves along the side guide rail 102 of the bed to the side position (near the head end) of the CNC cutting area 12. The pushing mechanism 42 (such as a pushing plate or pushing claw) on the CNC cutting and pushing machine 4 extends and pushes the finished sheet metal and frame waste that have been cut on the vacuum adsorption processing table toward the discharge area 13.

[0045] The discharge belt conveyor 131 in the discharge area 13 receives the finished products and waste materials that are pushed in. The operation of the discharge belt conveyor 131 transports the mixed materials to the end of the discharge area 13. At the end of the discharge area 13, the operators sort and classify the finished products and waste materials. The finished products are put into storage or enter the next process, and the waste materials fall into the waste collection box.

[0046] VI. Looping and Parallel Operations After completing the above steps, each component returns to its initial position: The first Y-axis moving mechanism 23 of the gantry-type non-destructive feeding machine 2 drives the X-axis crossbeam 22 back to the waiting area 14, ready to grab the next sheet.

[0047] The X-axis moving mechanism 32 of the automatic labeling and transferring machine 3 drives the gantry labeling bracket 31 back to the top of the automatic labeling area 11 (the safe position near the head end), waiting for the next sheet to be labeled.

[0048] The cutting X-axis moving mechanism of the CNC cutting and pushing machine 4 drives the cutting gantry 41 back to the top of the CNC cutting area 12 (the safe position near the end), waiting for the processing of the next sheet.

[0049] In the above process, the feeding action of the gantry-type non-destructive feeding machine 2 to the automatic labeling area 11, the transfer action of the automatic labeling and transferring machine 3 to the CNC cutting area 12 after labeling, and the pushing action of the CNC cutting and pushing machine 4 to the discharge area 13 after cutting are all performed by independent mechanisms and can be carried out simultaneously at different workstations without waiting for each other.

[0050] In summary, the non-destructive intelligent sheet metal cutting workstation of the present invention, through its overall architectural design of a shared basic bed, side guide rails, side waiting area, and segmented shuttle transfer, achieves the following advantages: 1. Labeling, cutting, and unloading are integrated into the same welded steel bed, and the two sets of transfer mechanisms share the same set of guide rails, eliminating the cumulative positioning error of multiple independent bases and improving accuracy.

[0051] 2. The gantry crane only straddles the front end, and the span and crossbeam length are much smaller than the traditional straddle-the-line scheme, which reduces the amount of steel used and the manufacturing cost; it also eliminates the need for deep foundation pit construction, thus reducing infrastructure investment.

[0052] 3. The automatic labeling and transferring machine and the CNC cutting and pushing machine operate independently in separate processes, realizing the overlap of action time and breaking the serial cycle limit of a single gantry machine, which is conducive to improving efficiency.

[0053] 4. The entire process uses vacuum suction cups to lift and transfer the entire board, eliminating mechanical grippers from contacting the board surface and preventing scratches and chips.

[0054] 5. The waiting area utilizes the space on the side of the bed, without increasing the total length of the equipment, saving workshop floor space. Forklifts can also enter directly from the side to change stacks, making operation convenient and the layout compact.

[0055] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
