Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly to a multi-mode processing method for a double-station three-dimensional laser cutting system. Background Art

[0002] Three-dimensional laser cutting machines are high-end equipment integrating optics, mechanics, electricity, and pneumatics, and are regarded as the pearl on the crown of laser processing equipment. They are mainly used for punching holes and trimming edges of complex stamping parts, and are widely used in fields such as aerospace and new energy vehicles.

[0003] Please refer to the Chinese patent application with the publication number CN117655557A. For the existing double-workbench laser cutting machine, both workbenches only have the function of alternately loading and unloading. That is, one workbench is loaded at the loading and unloading station at one end and then moves to the cutting station in the middle for cutting. At the same time, the other workbench moves to the loading and unloading station at the other end after cutting at the cutting station in the middle, unloads, and then reloads, and so on in an alternating manner.

[0004] Therefore, for the existing double-workbench laser cutting machine, workpieces can only be placed on one workbench for processing, which not only limits the maximum size of the workpieces, resulting in the laser cutting machine being unable to process large-sized workpieces and having poor versatility, but also the existing double-workbench laser cutting machine can usually only cut and process the same kind of workpiece in one processing cycle, with poor flexibility in use.

[0005] Moreover, most of the waste materials generated by the existing three-dimensional laser cutting machines (since the three-dimensional laser cutting machines are mainly used for punching holes and trimming edges, the waste materials generated by punching holes are usually circular metal sheets, and the waste materials generated by trimming edges are usually strip-shaped metal sheets) are mostly cleaned manually on the sliding table during machine downtime, with very low efficiency. Therefore, some three-dimensional laser cutting machines have added a self-cleaning mechanism for the sliding table, which has improved the production efficiency to a certain extent.

[0006] At the same time, after the laser cutting of the workpieces is completed, most of them are inspected manually with inspection tools after being taken offline, with low efficiency. Therefore, please refer to the Chinese utility model patent with the publication number CN219785648U. Some equipment has added a vision camera to perform online inspection on the workpieces, improving the inspection efficiency and inspection accuracy.

[0007] Therefore, for the existing three-dimensional laser cutting machines, the self-cleaning of the sliding table and the online vision inspection of the workpieces are both carried out in two processes, resulting in the overall low efficiency of workpiece processing. Summary of the Invention

[0008] In view of this, the present invention provides a multi-mode processing method for a double-station three-dimensional laser cutting system.

[0009] The technical solution is as follows:

[0010] The first aspect of this application relates to a multi-mode processing method for a two-station three-dimensional laser cutting system, which is carried out according to the following steps:

[0011] S1. Identify the size of the workpiece to be processed in the workpiece stacking area, and determine whether the size of the workpiece to be processed is greater than the set value: if yes, go to step S2; if no, go to step S4;

[0012] S2. Two slides that are not loaded with workpieces are simultaneously located outside one of the slide inlets and outlets of the bed, and after completion, proceed to the next step;

[0013] S3. A robotic arm adjacent to the two slides transfers a workpiece to be processed to the two slides, and after completion, go to step S6;

[0014] S4. A slide that is not loaded with a workpiece is located outside one of the slide inlets and outlets of the bed, and after completion, proceed to the next step;

[0015] S5. The robotic arm adjacent to the slide not loaded with a workpiece transfers a workpiece to be processed to this slide, and after completion, go to step S6;

[0016] S6. The slide transfers the workpiece to be processed to the inside of the bed, and then the crossbeam module performs laser cutting on the workpiece to be processed. After completion, proceed to the next step;

[0017] S7. During the process of transferring the processed workpiece to the side inlet and outlet, the waste removal mechanism removes the waste on the slide to the waste collection box, and then the vision inspection component detects whether the processed workpiece is qualified: if no, go to step S8; if yes, go to step S10;

[0018] S8. Determine the repair method required for the unqualified part: if it requires the crossbeam module, return to step S6; if it requires manual operation, go to step S9;

[0019] S9. A robotic arm adjacent to the unqualified part transfers the unqualified part to the unqualified part stacking area, and after completion, go to step S1;

[0020] S10. A robotic arm adjacent to the qualified part transfers the qualified part to the qualified part stacking area, and after completion, go to step S1.

[0021] The multi-mode processing method using the above double-station three-dimensional laser cutting system not only has the function of alternately loading and unloading of the existing three-dimensional laser cutting machine; but also, due to the setting of two sets of crossbeam modules, and through the one-to-one correspondence between the two sets of crossbeam modules and the two sliding tables, it can not only process the same workpiece, but also each process a different workpiece, improving the flexibility of use; moreover, the two sliding tables can cooperate to load and unload materials outside the inlet and outlet of one sliding table, and at the same time, the two sets of crossbeam modules can cooperate to process a large workpiece, thus doubling the size limit of the workpiece to be processed and greatly improving the versatility of the equipment; in addition, a side inlet and outlet is added on one side in the width direction of the bed body, and at the same time, the positioning tooling on the sliding table can move along the width direction of the bed body under the drive of the tooling translation component, so that when the sliding table is located beside the side inlet and outlet, the vision detection component can perform on-line vision detection on the workpiece on the positioning tooling. At the same time, the positioning tooling will synchronously drive the waste removal mechanism to remove the waste on the tooling base to the waste collection box, completing two processes in one step, not only greatly improving the processing efficiency, but also having a clever mechanical structure design and a high degree of integration; at the same time, the sliding table module can provide two on-line adjustable degrees of freedom in the horizontal direction, and then cooperate with the multiple degrees of freedom realized on the crossbeam module, so as to realize a redundant processing mode with super multiple degrees of freedom, which can not only perform laser cutting processing more efficiently, but also perform laser cutting processing more flexibly, so that it can be applied to the cutting processing of more complex surfaces and obtain higher processing accuracy.

[0043] The present invention will be further described below in conjunction with embodiments and the accompanying drawings.

[0044] Embodiment 1:

[0045] As Figure 2 and Figure 3 shown, a double-station three-dimensional laser cutting system mainly includes a bed 12, a track sliding table conveying mechanism 17 and two sets of crossbeam modules.

[0046] Please refer to Figures 2 - 4 At both ends of the bed body 12 in the length direction, there are slide table inlets and outlets 12c, and on one side of the bed body 12 in the width direction, there is a side inlet and outlet 12d. At the side inlet and outlet 12d, two waste collection bins 25 are arranged side by side. Specifically, the bed body 12 includes five columns 12a and a top frame 12b installed on the tops of the five columns 12a at the same time. Among them, the top frame 12b is a rectangular frame structure. Specifically, the top frame 12b is formed by enclosing a rectangular structure by two relatively arranged main beams 12b1 and two relatively arranged side beams 12b2. Four of the columns 12a are respectively supported at the four corners of the top frame 12b, that is: the four corners of the top frame 12b are respectively fixed at the tops of the four columns 12a. The other column 12a is supported at the middle position of one of the main beams 12b1, so that slide table inlets and outlets 12c are formed under both side beams 12b2 of the bed body 12, that is: the two slide table inlets and outlets 12c are located at both ends of the bed body 12 in the length direction; at the same time, a side inlet and outlet 12d is formed under the main beam 12b1 of the bed body 12 supported on two columns 12a, and the two waste collection bins 25 are located directly below the main beam 12b1, that is: the side inlet and outlet 12d is located on one side of the bed body 12 in the width direction. Among them, the extending directions of the two main beams 12b1 are the length direction of the bed body 12, the extending directions of the two side beams 12b2 are the width direction of the bed body 12, and the extending direction of the column 12a is the height direction of the bed body 12.

[0047] The above design not only ensures the structural strength of the bed body, but also is easy to expand and arrange functions at the position of the side inlet and outlet 12d.

[0048] In this embodiment, each column 12a includes a column body 12a1 extending in the vertical direction, a column top plate 12a2 and a column bottom plate 12a3 respectively fixedly installed at the top and bottom of the column body 12a1. A number of column reinforcing plates 12a4 extending in the vertical direction are installed on the circumference of the column body 12a1. The tops of the column reinforcing plates 12a4 are respectively fixedly connected to the corresponding column top plates 12a2, and the bottoms of the column reinforcing plates 12a4 are respectively fixedly connected to the corresponding column bottom plates 12a3. Therefore, the structural strength of each column 12a is greatly improved, and thus the structural strength of the bed body 12 is further improved.

[0049] Furthermore, in order to improve the structural strength of the bed body 12, top frame reinforcing triangular ribs 12b3 are installed at the boundaries of the top frame 12b, thereby improving the structural strength of the top frame 12b. At the same time, in order to improve the connection strength between the top frame 12b and each column 12a, top frame reinforcing triangular plates 12b4 are also provided at the connection positions between the top frame 12b and each column 12a.

[0050] Please refer to Figures 9 - 20The crossbeam module mainly includes a crossbeam 6, a Y-axis slide 2, a Z-axis sleeve 1 and a laser cutting head 5.

[0051] The crossbeam 6 is composed of two strip slides 6b and two end connection seats 6c. The two strip slides 6b and the two end connection seats 6c are preferably integrally formed by a casting process, and the structural strength is high. The two strip slides 6b are both columnar or strip-shaped structures, and the two strip slides 6b are parallel to each other. The two end connection seats 6c are arranged at both ends of the two strip slides 6b, that is, one of the end connection seats 6c is fixedly connected to one end of the two strip slides 6b, and the other end connection seat 6c is fixedly connected to the other end of the two strip slides 6b.

[0052] In this embodiment, the gap between the two strip slides 6b forms a Z-axis sleeve clearance groove 6a extending in the horizontal direction, and the two ends of the Z-axis sleeve clearance groove 6a are defined by the two strip slides 6b. In addition, the upper part of the strip slide 6b is provided with a Y-direction sliding component installation structure 6b1, and the end connecting seat 6c is provided with an X-direction drive device installation structure 6c1, so that the center of gravity of the Y-axis slide 2 and the Z-axis sleeve 1 is located at the center of the beam 6, which greatly improves the stability and reliability of the Y-axis slide 2 and the Z-axis sleeve 1, and does not need to be frequently corrected and debugged, and it is not easy to cause torsional deformation of the beam 6, so that the static and dynamic characteristics of the three-dimensional laser cutting machine are excellent.

[0053] Therefore, the crossbeam 6 of this embodiment enables the Y-axis slide 2 to be installed on the two Y-direction sliding component mounting structures 6b1, and at the same time the Z-axis sleeve 1 can be inserted into the Z-axis sleeve clearance groove 6a, thereby cooperating with the Y-axis slide 2 to realize a centrally placed straddle-type installation on the crossbeam 6.

[0054] Furthermore, the upper parts of the two strip-shaped slide seats 6b have upper support surfaces 6b2 that are both inclined, and the two upper support surfaces 6b2 are symmetrically inclined downward in a direction away from each other, that is, the two upper support surfaces 6b2 together form an "eight"-shaped structure. At the same time, the Y-axis sliding assembly mounting structure 6b1 includes mounting bosses 6b11 protruding from the corresponding upper support surfaces 6b2, and the mounting bosses 6b11 extend along the length direction of the corresponding upper support surfaces 6b2. The two mounting bosses 6b11 are protruding on the side away from each other to form support ribs 6b12, and the mounting bosses 6b11 are mounted with second linear guides 7 extending along the length direction thereof, and the slide rails of each second linear guide 7 are respectively supported on the corresponding support ribs 6b12. Therefore, not only is the reliable installation of the second linear guide 7 guaranteed, but the two second linear guides 7 also together form an "eight"-shaped structure.

[0055] In this embodiment, at least one upper support surface 6b2 is formed with a rack mounting horizontal surface 6b3 extending in the horizontal direction on the side close to the Z-axis sleeve relief groove 6a. A rack mounting pad 11 extending along the length direction of the Z-axis sleeve relief groove 6a is mounted on one of the rack mounting horizontal surfaces 6b3. A rack support rib 11a protrudes from the top surface of the rack mounting pad 11 on the side away from the Z-axis sleeve relief groove 6a. A second rack 8 extending along the length direction of the rack mounting pad 11 is mounted on the rack mounting pad 11, and the side of the second rack 8 away from the Z-axis sleeve relief groove 6a is supported on the rack support rib 11a, ensuring the reliable installation of the second rack 8.

[0056] Furthermore, the interior of the strip-shaped sliding seat 6b is a hollow structure extending along its length direction to meet the requirements of lightweight design. At the same time, a number of reinforcing support ribs 6b4 distributed along the length direction are provided inside the strip-shaped sliding seat 6b, thus ensuring the structural strength of the strip-shaped sliding seat 6b.

[0057] Moreover, a number of weight-reducing openings 6b5 distributed along the length direction are formed on the side walls of the strip-shaped sliding seats 6b close to each other, and the respective reinforcing support ribs 6b4 are located at both ends of the corresponding weight-reducing openings 6b5, not only meeting the requirements of lightweight design, but also facilitating the welding of the reinforcing support ribs 6b4.

[0058] In this embodiment, the X-direction driving device mounting structures 6c1 are respectively motor mounting grooves formed by recessing from the top surfaces of the corresponding end connectors 6c, facilitating the installation of the motors. At the same time, a number of triangular reinforcing ribs 6c2 are provided on the groove walls of the two motor mounting grooves, ensuring the structural strength at the positions of the motor mounting grooves.

[0059] Furthermore, triangular reinforcing ribs 6d are provided at the four corners of the Z-axis sleeve relief groove 6a to improve the structural strength at the connection between the strip-shaped sliding seat 6b and the end connector 6c.

[0060] The Z-axis sleeve 1 includes an integrally formed flat tube portion 1a and a cylindrical tube portion 1b, with high structural strength. Among them, the flat tube portion 1a is a flat tubular structure, and the flat tube portion 1a extends in the vertical direction. The cylindrical tube portion 1b is a cylindrical structure, and the cylindrical tube portion 1b also extends in the vertical direction. At the same time, the cylindrical tube portion 1b is located at the lower end of the flat tube portion 1a.

[0061] In this embodiment, the flat tube portion 1a and the cylindrical tube portion 1b are coaxially arranged. Most importantly, lifting guide planes 1a1 extending in the vertical direction are provided in parallel on both sides in the width direction of the flat tube portion 1a. And the distance between the two lifting guide planes 1a1 is smaller than the diameter of the cylindrical tube portion 1b. At the same time, the cylindrical tube portion 1b protrudes radially from the two lifting guide planes 1a1. In addition, lifting control component mounting structures extending in the vertical direction are provided on the lifting guide planes 1a1.

[0062] The flat tube portion 1a is used to cooperate with the Y-axis slide 2, that is, the flat tube portion 1a can move up and down along the Y-axis slide 2. The cylindrical tube portion 1b is used to install the laser cutting head 5. Specifically, the laser cutting head 5 extends downward from the cylindrical tube portion 1b. Among them, the laser cutting head 5 adopts a traditional laser cutting head that can emit laser, and usually has one or two or more rotational degrees of freedom, which can be selected according to actual needs.

[0063] Therefore, on the premise of meeting the wiring requirements, the flat tube portion 1a can be designed to be ultra-thin, that is, the distance between the two lifting guide planes 1a1 can be designed to be very small. Therefore, the width of the Y-axis slide 2 that cooperates with it can also be very small, thereby reducing the size and weight of the Y-axis slide 2 and meeting the requirements of lightweight design. And because the Z-axis sleeve 1 and the Y-axis slide 2 form an irregular shaft-hole fit through the flat tube portion 1a, there will be no relative rotation between them, so there will be no misassembly problem during assembly, and the assembly tolerance can be greatly reduced, shortening the assembly and debugging cycle; at the same time, because the widths of the flat tube portion 1a and the Y-axis slide 2 are both very small, the width of the Z-axis sleeve relief groove 6a of the cross beam 6 that cooperates with them can be greatly reduced, thereby effectively improving the structural strength of the cross beam 6, not easily occurring bending deformation problems, and reducing the maintenance frequency and use cost.

[0064] Two wire routing relief grooves 1a2 are recessed on the inner wall of the flat tube portion 1a and are arranged opposite to each other. Both of the two wire routing relief grooves 1a2 are arranged along the vertical direction on the inner side of the corresponding lifting guide plane 1a1. Therefore, while ensuring the structural strength of the flat tube portion 1a itself, the middle part of the flat tube portion 1a has two wire routing relief grooves 1a2 through the enlarged-diameter profile, which is convenient for wire routing.

[0065] Furthermore, the cross-section of the flat tube portion 1a is approximately rectangular. Specifically, the outer wall of the circumference of the flat tube portion 1a is surrounded by two relatively arranged lifting guide planes 1a1 and two relatively arranged arc surfaces 1a5. The lifting guide planes 1a1 are both plane structures, and the arc surfaces 1a5 are both arc surface structures protruding outward. The lifting guide planes 1a1 and the arc surfaces 1a5 both extend along the vertical direction. Among them, because the arc surface 1a5 is an arc-shaped thin plate structure, it is not only easy to cast, but also has higher structural strength than the conventional flat plate structure.

[0066] In this embodiment, since both of the two lifting guide planes 1a1 protrude from the cylindrical tube portion 1b horizontally to both sides, the internal space of the flat tube portion 1a can be effectively increased, so that more wire harnesses can pass through without increasing the width of the flat tube portion 1a.

[0067] The Z-axis sleeve 1 of this embodiment is integrally formed by a casting process, and has high structural strength.

[0068] The Y-axis slide base 2 has an annular structure. Specifically, the Y-axis slide base 2 is formed by enclosing two relatively arranged slider mounting components and two relatively arranged buckle components, that is: the two slider mounting components face each other, the two buckle components face each other, and the two slider mounting components and the two buckle components are arranged in a rectangle, thus jointly forming an annular structure.

[0069] Each slider mounting component includes a crossbeam slider mounting base 2a and two sleeve slider mounting bases 2b. The crossbeam slider mounting base 2a includes a vertically extending vertical mounting plate 2a1 and a slider connecting plate 2a2 formed by bending outward from the bottom of the vertical mounting plate 2a1. The two slider connecting plates 2a2 are respectively parallel to the corresponding upper support surface 6b2, and Y-direction slider connection structures 2a21 are provided on both of the two slider connecting plates 2a2. Among them, the slider connecting plate 2a2 can be arranged perpendicular to the vertical mounting plate 2a1 or inclined to the vertical mounting plate 2a1.

[0070] Furthermore, in this embodiment, the slider connecting plate 2a2 preferably extends outward from the lower edge of the corresponding vertical mounting plate 2a1 and inclines downward, so that the two slider connecting plates 2a2 of the two slider mounting components jointly form a "V" shape structure (matched with the second linear guide rail 7).

[0071] Therefore, when the Y-axis slide base 2 translates, it can apply pressure to the crossbeam 6 through the way of inclined plane cooperation. Compared with the structure where the slider connecting plate 2a2 is perpendicular to the vertical mounting plate 2a1 applying pressure to the crossbeam 6, the way in this embodiment can reduce the pressure borne by the crossbeam 6, so that the structural stability of the crossbeam 6 is better and the risk of the middle part of the crossbeam 6 sagging and bending is reduced.

[0072] Furthermore, at least one triangular reinforcing rib 2a3 is provided between the outer surface of the vertical mounting plate 2a1 and the upper surface of the slider connecting plate 2a2, so as to effectively improve the structural strength of the crossbeam slider mounting base 2a and avoid deformation.

[0073] Z-direction slider connection structures 2b1 are provided on all four sleeve slider mounting bases 2b. Connection bosses 2b2 adapted to the corresponding vertical mounting plates 2a1 are provided on the outer sides of the sleeve slider mounting bases 2b, and each connection boss 2b2 can be adjustably mounted on the inner side of the corresponding vertical mounting plate 2a1. Each buckle component is composed of at least one vertically arranged buckle 2c. Both ends of each buckle 2c are bent inward to form buckle connecting arms 2c1. Connection arm slots 2b21 adapted to the corresponding buckle connecting arms 2c1 are provided on the side walls of each connection boss 2b2, and each buckle connecting arm 2c1 can be adjustably mounted in the corresponding connection arm slot 2b21. Therefore, the size of the Y-axis slide base 2 in the circumferential direction is adjustable.

[0074] The Y-axis slide 2 of this embodiment can be connected to the cross beam 6 in a central straddle-mounted manner by setting two Y-direction slider connection structures 2a21. Compared with the existing offset-mounted structure of the Y-axis slide, the Y-axis slide 2 of this embodiment not only makes the overall center of gravity in the central position, thus making the installation of the Y-axis slide 2 stable and reliable, without the need for frequent deviation correction debugging, and not easily causing torsional deformation of the cross beam 6, making the static and dynamic characteristics of the three-dimensional laser cutting machine excellent. At the same time, since the Y-axis slide adopts a split structure, it can be very conveniently assembled with the Z-axis sleeve 1, and can adapt to Z-axis sleeves 1 of different sizes by replacing latches 2c of different sizes or adjusting the connection position between the latch connecting arm 2c1 and the connecting arm slot 2b21, with good versatility. Moreover, the split-structured Y-axis slide can very conveniently correct the assembly error and coordinate with the processing precision debugging of the later equipment by adjusting the connection position between the latch connecting arm 2c1 and the connecting arm slot 2b21 and the connection position between the connecting boss 2b2 and the vertical mounting plate 2a1.

[0075] On the outer sides of the connecting bosses 2b2, a first bolt hole array 2b22 composed of bolt holes distributed in an array is provided, that is: the first bolt hole array 2b22 is composed of bolt holes distributed in multiple rows and multiple columns in an array, and the inner ends of the bolt holes of the first bolt hole array 2b22 all penetrate through to the corresponding connecting arm slots 2b21.

[0076] At the same time, on the vertical mounting plates 2a1, two second bolt hole arrays 2a11 composed of bolt holes distributed in an array are provided, that is: the second bolt hole arrays 2a11 are composed of bolt holes distributed in multiple rows and multiple columns in an array. On the latch connecting arms 2c1, a bolt hole linear array 2c11 composed of bolt holes evenly distributed along the length direction is provided.

[0077] The aperture and spacing of adjacent bolt holes of the first bolt hole array 2b22, adjacent bolt holes of the second bolt hole array 2a11, and adjacent bolt holes of the bolt hole linear array 2c11 are all the same, and at least one bolt hole of each bolt hole linear array 2c11 communicates with the bolt holes of the corresponding first bolt hole array 2b22 and the second bolt hole array 2a11, and is locked into one body by bolts (not shown in the figure). When it is necessary to adjust the size and structure of the Y-axis slide 2, only need to take out the bolts, then adjust the relative positions on the sleeve slider mounting seat 2b and the cross beam slider mounting seat 2a, and the relative position between the latch 2c and the sleeve slider mounting seat 2b. After it is in place, lock the bolts again, which is simple and reliable.

[0078] In this embodiment, two first linear guide rails 1c extending in the vertical direction are installed on both of the two lifting guide planes 1a1. A first rack 1d extending in the vertical direction is installed on one of the lifting guide planes 1a1. Two slider mounting assemblies are correspondingly arranged on the outer sides of the two lifting guide planes 1a1, and two buckle assemblies are correspondingly arranged on the outer sides of the two arc surfaces 1a5. Four Z-direction slider connection structures 2b1 are fixedly connected to the sliders of the four first linear guide rails 1c correspondingly. A first driving motor 3 is installed on the crossbeam slider mounting seat 2a close to the first rack 1d, and a first driving gear 4 meshing with the first rack 1d is sleeved on the motor shaft of the first driving motor 3 synchronously and rotatably.

[0079] Therefore, by driving the first driving gear 4 to rotate forward and backward through the motor shaft of the first driving motor 3, the Z-axis sleeve 1 can be lifted or lowered along the Y-axis slide, with high control precision. Further, the first driving motor 3 is preferably a servo motor, which can further improve the precision control of the lifting of the Z-axis sleeve 1.

[0080] Among them, the Y-direction slider connection structure 2a21 includes a Y-direction slider limiting rib 2a211 integrally formed on the lower side of the slider connecting plate 2a2 and a third bolt hole array 2a212 penetrating the slider connecting plate 2a2 in the thickness direction. The third bolt hole array 2a212 is composed of bolt holes distributed in an array. After the slider of the first linear guide rail 1c is positioned on the Y-direction slider limiting rib 2a211, it is connected to the third bolt hole array 2a212 by bolts, which is simple and reliable.

[0081] Similarly, two Y-direction slider connection structures 2a21 are fixedly connected to the sliders of the two second linear guide rails 7 correspondingly. A second driving motor 9 is installed on the crossbeam slider mounting seat 2a far from the first rack 1d, and a second driving gear 10 meshing with the second rack 8 is sleeved on the motor shaft of the second driving motor 9 synchronously and rotatably.

[0082] Therefore, by driving the second driving gear 10 to rotate forward and backward through the motor shaft of the second driving motor 9, the Y-axis slide can be translated along the crossbeam 6, with high control precision. Further, the second driving motor 9 is preferably a servo motor, which can further improve the precision control of the translation of the Y-axis slide.

[0083] Among them, the Z-direction slider connection structure 2b1 includes a Z-direction slider limiting rib 2b11 integrally formed on the side of the sleeve slider mounting seat 2b away from the slider connecting plate 2a2 and a fourth bolt hole array 2b12 penetrating the sleeve slider mounting seat 2b in the thickness direction. The fourth bolt hole array 2b12 is composed of bolt holes distributed in an array. After the slider of the second linear guide rail 7 is positioned on the Z-direction slider limiting rib 2b11, it is connected to the fourth bolt hole array 2b12 by bolts, which is simple and reliable.

[0084] In this embodiment, the first rack 1d and each first linear guide 1c are respectively installed on the corresponding lifting control component installation structure. Specifically, a plurality of flat cylinder part reinforcing ribs 1a3 are convexly formed on the lifting guide plane 1a1, improving the structural strength of the flat cylinder part 1a. At the same time, some of the flat cylinder part reinforcing ribs 1a3 extending in the vertical direction are the lifting control component installation structure, and the first rack 1d and each first linear guide 1c are respectively installed on the flat cylinder part reinforcing ribs 1c extending in the vertical direction, ensuring the installation accuracy of the first rack 1d and each first linear guide 1c.

[0085] Furthermore, a circular reinforcing flange 1a4 is convexly formed along the circumference at the top of the flat cylinder part 1a, thereby improving the structural strength at the entrance of the flat cylinder part 1a. At the same time, the upper parts of the flat cylinder part reinforcing ribs 1a3 extending in the vertical direction all extend to the circular reinforcing flange 1a4, improving the overall structural strength of the flat cylinder part 1a. And the upper ends of the first rack 1d and each first linear guide 1c are both in contact with the circular reinforcing flange 1a4, thereby further improving the installation accuracy of the first rack 1d and each first linear guide 1c.

[0086] Furthermore, a plurality of annular reinforcing ribs 1b1 arranged side by side along the axial direction and axial reinforcing ribs 1b2 evenly distributed circumferentially along each annular reinforcing rib 1b1 are convexly formed on the outer peripheral surface of the cylindrical part 1b. Each annular reinforcing rib 1b1 and each axial reinforcing rib 1b2 together form a grid-like structure, thereby effectively improving the structural strength of the cylindrical part 1b.

[0087] Furthermore, a first motor mounting seat 2a4 is provided on the crossbeam slider mounting seat 2a close to the first rack 1d, and the first driving motor 3 is installed on the first motor mounting seat 2a4, ensuring the reliable installation of the first driving motor 3. A second motor mounting seat 2a5 is provided on the crossbeam slider mounting seat 2a close to the second rack 8, and the second driving motor 9 is installed on the second motor mounting seat 2a5, ensuring the reliable installation of the second driving motor 9.

[0088] In this embodiment, two mutually parallel third linear guides 13 are installed on the top of the bed body 12, and a third rack 14 parallel to each of them is installed beside the two third linear guides 13, that is: a third linear guide 13 and a third rack 14 are installed on the top of the main beam 12b1 along the length direction thereof. At the same time, third driving motors 15 are installed on the respective end connectors 6c of the two sets of crossbeam modules, and third driving gears 16 meshing with the corresponding third racks 14 are synchronously rotated and sleeved on the motor shafts of the two third driving motors 15 of each set of crossbeam modules.

[0089] The crossbeams 6 of the two sets of crossbeam modules are installed on the corresponding sliders of the two third linear guide rails 13 in parallel, and the extending directions of the two crossbeams 6 are perpendicular to the extending directions of the two third linear guide rails 13. Generally, the extending direction of the third linear guide rail 13 is the X direction, the extending direction of the crossbeam 6 is the Y direction, and the extending direction of the Z-axis sleeve 1 is the Z direction.

[0090] Therefore, by driving the third driving gear 16 to rotate forward and backward through the motor shaft of the third driving motor 15, the translation of the crossbeam 6 can be controlled with high control precision. Further, the third driving motor 15 is preferably a servo motor, which can further improve the precision control of the translation of the crossbeam 6.

[0091] In the above structure, the two third linear guide rails 13 and the two third racks 14 that are both installed along the length direction of the bed 12 on the top of the bed 12 and the two third driving motors 15 fixedly installed on the corresponding end connectors 6c respectively form a crossbeam driving assembly. The two end connectors 6c are installed on the sliders of the two third linear guide rails 13 in a one-to-one correspondence, and third driving gears 16 that are respectively meshed with the corresponding third racks 14 are sleeved on the motor shafts of the respective third driving motors 15 and rotate synchronously.

[0092] The two second linear guide rails 7 and one second rack 8 that are both installed along the width direction of the bed 12 and the second driving motor 9 fixedly installed on the Y-axis slide 2 form a slide driving assembly. The second rack 8 and one of the second linear guide rails 7 are fixedly installed on one of the strip-shaped slides 6b in the crossbeam 6, and the other second linear guide rail 7 is fixedly installed on the other strip-shaped slide 6b in the crossbeam 6. The Y-axis slide 2 is fixedly installed on the sliders of the respective second linear guide rails 7, and a second driving gear 10 that is meshed with the second rack 8 is sleeved on the motor shaft of the second driving motor 9 and rotates synchronously.

[0093] The first rack 1d and at least one first linear guide rail 1c that are both installed along the vertical direction on the Z-axis sleeve 1 and the first driving motor 3 fixedly installed on the Y-axis slide 2 form a sleeve driving assembly. The Y-axis slide 2 is fixedly connected to the sliders of the respective first linear guide rails 1c, and a first driving gear 4 that is meshed with the first rack 1d is sleeved on the motor shaft of the first driving motor 3 and rotates synchronously.

[0094] Please refer to Figure 2 、 Figure 3 and Figure 21 , two vision detection components 26 are installed on the main beam 12b1 at the side inlet and outlet 12d. Two waste collection bins 25 are installed below the main beam 12b1, and the two vision detection components 26 are respectively arranged directly above the two waste collection bins 25. Among them, the vision detection component 26 is used for vision detection of the workpieces after laser cutting, and the waste collection bin 25 is used for centralized collection of waste.

[0095] The vision detection component 26 includes a camera base 26a fixedly mounted on the main beam 12b1, a sixth linear guide 26b and a sixth rack 26c both fixedly mounted on the camera base 26a along the length direction of the main beam 12b1, a camera mounting seat 26d mounted on the slider of the sixth linear guide 26b, and a sixth motor 26e and a vision camera 26f both fixedly mounted on the camera mounting seat 26d. The lens of the vision camera 26f faces downward, and sixth driving gears 26g meshing with the sixth rack 26c are sleeved on the motor shafts of the sixth motor 26e in a synchronously rotating manner.

[0096] Therefore, by driving the sixth driving gear 26g to rotate forward and backward through the motor shaft of the sixth motor 26e, the translation of the camera mounting seat 26d can be driven, so as to flexibly adjust the position of the vision camera 26f to adapt to the workpiece to be detected with a large size and a complex surface structure, and the control accuracy is high. Further, the sixth motor 26e preferably adopts a servo motor, which can further improve the adjustment accuracy of the position of the vision camera 26f.

[0097] Moreover, through the position adjustment of the two vision cameras 26f, the vision detection of a workpiece can also be carried out cooperatively to improve the efficiency of vision detection and avoid the occurrence of vision detection dead angles at the same time.

[0098] A light bar 26h extending along the length direction of the main beam 12b1 is mounted at the bottom of the camera base 26a. The light bar 26h is located on the side of the sixth linear guide 26b away from the sixth rack 26c, so as to provide sufficient light source for the shooting of the vision camera 26f and ensure the quality of vision detection.

[0099] A wire harness guiding and limiting hole 26a1 is also formed in the camera base 26a. The wire harness guiding and limiting hole 26a1 is located between the light bar 26h and the sixth linear guide 26b, so as to guide and limit the wire harness and avoid problems such as wire harness entanglement.

[0100] Further, a wire harness limiting hole 26d1 is also formed in the camera mounting seat 26d, so as to reliably limit the wire harness connecting the vision camera 26f and the sixth motor 26e.

[0101] In this embodiment, the camera base 26a includes a base body 26a2 fixedly connected to the main beam 12b1, a vertical mounting plate 26a3 extending downward from the outer edge of the base body 26a2 on the side away from the slide rail 17a, and a horizontal mounting plate 26a4 extending horizontally from the lower edge of the vertical mounting plate 26a3 in a direction away from the slide rail 17a. The sixth rack 26c is fixedly installed on the side of the vertical mounting plate 26a3 close to the slide rail 17a, and both the light bar 26h and the sixth linear guide rail 26b are installed on the bottom surface of the horizontal mounting plate 26a4, thus ensuring the reliable installation of the sixth rack 26c, the light bar 26h, and the sixth linear guide rail 26b. The wire harness guiding and limiting holes 26a1 are opened on the horizontal mounting plate 26a4, and multiple reinforcing thin plates 26a5 are connected between the vertical mounting plate 26a3 and the horizontal mounting plate 26a4, improving the structural strength between the vertical mounting plate 26a3 and the horizontal mounting plate 26a4.

[0102] Furthermore, the base body 26a2 is in an inverted "T" - shaped structure and is fixed to the main beam 12b1 by multiple bolts, ensuring the stability and reliability of the installation, and thus ensuring the quality of visual inspection.

[0103] Please refer to Figures 2 - 8 , the track - slide conveying mechanism 17 includes a slide rail 17a and two slides 17b that can move along the length direction of the slide rail 17a driven by a slide driving assembly. Usually, the slide rail 17a extends along the X - axis direction.

[0104] Positioning jigs 18 that can move along the width direction of the slide rail 17a driven by the tooling translation assembly 19 are installed on both slides 17b.

[0105] Among them, each tooling translation assembly 19 includes a tooling base 19a fixedly installed on the corresponding slide 17b and a tooling translation module for driving the positioning jig 18 to move along the width direction of the slide rail 17a on the tooling base 19a. At least one set of waste - removing mechanisms 24 for removing waste on the upper surface of the tooling base 19a into the waste collection box 25 are synchronously connected to the positioning jigs 18.

[0106] Therefore, the sliding table module of this embodiment can provide two online-adjustable degrees of freedom in the horizontal direction, and cooperate with multiple degrees of freedom realized on the crossbeam module, so as to realize a redundant processing mode with a large number of degrees of freedom, which can not only perform laser cutting processing more efficiently, but also perform laser cutting processing more flexibly, so that it can be applied to the cutting processing of more complex profiles and obtain higher processing accuracy; and when online visual inspection of the workpiece is required, the positioning tooling 18 moves along the width direction of the sliding table track 17a to directly below the visual inspection component 26. At the same time, the positioning tooling 18 will synchronously drive the waste removal mechanism 24 to remove the waste on the tooling base 18 into the waste collection box 25, completing two processes in one step, that is: each time the positioning tooling 18 transfers the workpiece to be inspected to directly below the visual inspection component 26, each waste removal mechanism 24 also synchronously removes the waste on the tooling base 18 into the waste collection box 25, which not only greatly improves the processing efficiency, but also has a clever mechanical structure design and a high degree of integration. Especially for circular metal sheets, they can be easily pushed to roll out of the sliding table by their own inertia, which not only has high efficiency and little impact on the production rhythm, but for strip-shaped metal sheets, the working stroke of the waste removal mechanism 24 needs to cover the tooling base 19a as much as possible.

[0107] The tooling bases 19a each include a material receiving plate 19a1 fixedly installed on the corresponding sliding table 17b and two guide rail mounting brackets 19a2. The two guide rail mounting brackets 19a2 are relatively installed on both sides of the material receiving plate 19a1 along the length direction of the sliding table track 17a. The two guide rail mounting brackets 19a2 are preferably fixedly installed on the sliding table 17b and fixedly connected to the material receiving plate 19a1, ensuring the stability and reliability of the tooling base 19a.

[0108] The tooling translation modules each include a fourth linear guide rail 19c installed on one of the guide rail mounting brackets 19a2 and a fourth linear guide rail 19c and a fourth rack 19b installed on the other guide rail mounting bracket 19a2. The fourth rack 19b and the fourth linear guide rail 19c both extend along the width direction of the sliding table track 17a. The positioning tooling 18 includes a driving carriage 18a and a driven carriage 18b on both sides of the material receiving plate 19a1. The driving carriage 18a and the driven carriage 18b are respectively fixedly installed on the sliders of the corresponding fourth linear guide rails 19c. A fourth motor 19d is installed on the driving carriage 18a, and fourth driving gears 19e meshing with the fourth rack 19b are synchronously sleeved on the motor shafts of the fourth motor 19d. When the workpiece is fixed on the driving carriage 18a and the driven carriage 18b, the driving carriage 18a and the driven carriage 18b move synchronously.

[0109] Therefore, by driving the fourth drive gear 19e to rotate forward and backward, the motor shaft of the fourth motor 19d can control the translation of the positioning tooling 18, with high control precision. Further, the fourth motor 19d is preferably a servo motor, which can further improve the precision control of the translation of the positioning tooling 18.

[0110] In this embodiment, a set of waste removal mechanisms 24 for removing the waste on the upper surface of the receiving plate 19a1 to one side in the width direction of the slide table track 17a are installed on both the active carriage 18a and the driven carriage 18b, so as to achieve a better cleaning effect on the upper surface of the receiving plate 19a1.

[0111] Two receiving grooves 19a11 respectively located below the corresponding waste removal mechanisms 24 are recessed on the upper surface of the receiving plate 19a1, so as to reliably collect the waste generated by laser cutting. At the same time, each waste removal mechanism 24 includes a connection component 24a installed on the corresponding active carriage 18a or driven carriage 18b and a removal component 24b for removing the waste in the corresponding receiving groove 19a11 to one side in the width direction of the slide table track 17a. Each group of removal components 24b independently removes the waste in the receiving groove 19a11, with high reliability.

[0112] Specifically, a plurality of guide slots 19a12 penetrating the receiving plate 19a1 in the width direction of the slide table track 17a are recessed at the bottom of each receiving groove 19a11. Each removal component 24b includes a push-pull shaft 24b1 extending in the length direction of the slide table track 17a, a waste removal push block 24b2 slidably installed in the corresponding guide slot 19a12 one by one, and a push-pull crank 24b3 hinged to the same end of each waste removal push block 24b2 one by one. One end of each push-pull crank 24b3 away from the waste removal push block 24b2 is respectively hinged to the corresponding push-pull shaft 24b1. Each connection component 24a includes a push-pull plate 24a1 fixedly connected to the corresponding active carriage 18a or driven carriage 18b and a push-pull link 24a2 hinged to the corresponding push-pull plate 24a1. One end of each push-pull link 24a2 away from the push-pull plate 24a1 is respectively hinged to the corresponding push-pull shaft 24b1.

[0113] Therefore, when the active carriage 18a and the driven carriage 18b are translated synchronously, each push-pull plate 24a1 can push and pull the corresponding push-pull shaft 24b1 through the corresponding push-pull connecting rod 24a2. The push-pull shaft 24b1 then synchronously pushes and pulls the material-rejecting push block 24b2 through each push-pull crank 24b3, so that the waste materials in each material-guiding slit 19a12 can be pushed to the outside of the sliding table module. Since the cutting waste materials are usually metal flakes generated by punching (whether circular or strip-shaped), and the width of the material-guiding slit 19a12 is designed to be smaller than that of the metal flake, it can ensure that the metal flake is placed obliquely in the material-guiding slit 19a12 and is easily pushed by the material-rejecting push block 24b2. If the metal flake is circular, with a slight push from the material-rejecting push block 24b2, the circular metal flake can roll into the waste collection box 25 under the support of the side wall of the material-guiding slit 19a12 by using its own inertia.

[0114] Further, in order to make the metal flake easier to be pushed out of the material-guiding slit 19a12, in this embodiment, in the same material-receiving groove 19a11: each material-guiding slit 19a12 is arranged to be inclined downward synchronously from the end close to the push-pull shaft 24b1 to the other end of each material-rejecting push block 24b2, that is, it is inclined obliquely downward in the direction close to the waste collection box 25. Since each material-guiding slit 19a12 is designed to be inclined obliquely downward towards the output end, whether it is a circular metal flake or a strip-shaped metal flake, the material-rejecting push block 24b2 only needs to apply a relatively small thrust as set, and the circular metal flake and the strip-shaped metal flake can smoothly slide out along the material-guiding slit 19a12 under the action of their own gravity and inertia, which not only improves the cleaning ability and cleaning efficiency, but also can better avoid the jamming problem.

[0115] Further, in order to make the posture of the metal flake in the material-guiding slit 19a12 easier to be pushed by the material-rejecting push block 24b2, in this embodiment, the two side walls of the material-guiding slit 19a12 are mirror-image arranged, and each material-guiding slit 19a12 includes an inclined section 19a121 and a vertical section 19a122 distributed from bottom to top. Specifically, in the same material-guiding slit 19a12: the heights of the inclined sections 19a121 at each position are equal, and the heights of the vertical sections 19a122 at each position are also equal; among them, the two inclined sections 19a121 are both inclined-plane structures, and the distance between the two inclined sections 19a121 gradually increases in the direction close to the bottom of the groove, that is, the cross-section of the material-guiding slit 19a12 at the positions of the two inclined sections 19a121 is in a trapezoidal structure; the two vertical sections 19a122 are both vertical-plane structures, that is, the cross-section of the material-guiding slit 19a12 at the positions of the two vertical sections 19a122 is in a rectangular structure, so that the metal flake generated by laser cutting can be supported at the position of the inclined section 19a121 and has a certain angle with the vertical section 19a122, and thus is more easily pushed by the material-rejecting push block 24b2.

[0116] Correspondingly, each blanking push block 24b2 includes a connecting arm 24b21 hinged to the corresponding push-pull crank 24b3 and a blanking block 24b22 integrally formed at one end of the corresponding connecting arm 24b21 away from the push-pull crank 24b3. A reduced-diameter section 24b221 adapted to the corresponding two vertical sections 19a122 and a trapezoidal block section 24b222 adapted to the corresponding two inclined sections 19a121 are integrally formed at the lower part of each blanking block 24b22. Therefore, the metal flakes generated by laser cutting are both inclinedly supported in the material guiding slot 19a12 and do not completely adhere to the bottom or side wall of the material guiding slot 19a12, enabling the blanking push block 24b2 to very easily push the metal flakes in the material guiding slot 19a12 and avoiding jamming problems.

[0117] Furthermore, in this embodiment, the upper part of the blanking block 24b22 is designed to be relatively wide, so that the gap between the upper parts of adjacent blanking blocks 24b22 is very small (usually much smaller than the diameter or width of the metal flakes), so that the waste that has not fallen into the material guiding slot 19a12 can be pushed away together, ensuring the thoroughness of waste removal.

[0118] In this embodiment, in order to ensure the stability of the operation of the push-pull shaft 24b1, push-pull shaft guiding slots 19a13 adapted to the corresponding push-pull shafts 24b1 are provided on both side walls of the material receiving groove 19a11. Both ends of each push-pull shaft 24b1 are slidably fitted and embedded in the corresponding push-pull shaft guiding slots 19a13, thus ensuring the synchronism of the operation of each blanking push block 24b2 and avoiding jamming problems.

[0119] The active carriage 18a includes an active carriage base 18a1 fixedly installed on the slider of the corresponding fourth linear guide 19c, and an active carriage fixed mounting plate 18a2, an active carriage movable mounting plate 18a3, and an active carriage connecting seat 18a4 all installed on the active carriage base 18a1. The active carriage connecting seat 18a4 is fixedly installed at one end of the active carriage base 18a1 and is connected to the corresponding waste removal mechanism 24. The active carriage fixed mounting plate 18a2 is fixedly installed at the other end of the active carriage base 18a1. A first elongated hole 18a11 extending in the width direction of the bed 12 is provided in the middle of the active carriage base 18a1. The active carriage movable mounting plate 18a3 is slidably fitted and installed in the first elongated hole 18a11 through at least two bolts that can be locked or unlocked. The fourth motor 19d is installed beside the active carriage connecting seat 18a4.

[0120] Similarly, the driven carriage 18b includes a driven carriage base 18b1 fixedly mounted on the slider corresponding to the fourth linear guide 19c, and a driven carriage fixed mounting plate 18b2, a driven carriage movable mounting plate 18b3, and a driven carriage connecting seat 18b4 all mounted on the driven carriage base 18b1. The driven carriage connecting seat 18b4 is fixedly mounted at one end of the driven carriage base 18b1 and is connected to the corresponding waste removing mechanism 24. The driven carriage fixed mounting plate 18b2 is fixedly mounted at the other end of the driven carriage base 18b1. A second elongated hole 18b11 extending in the width direction of the bed 12 is provided in the middle of the driven carriage base 18b1. The driven carriage movable mounting plate 18b3 is slidably fitted in the second elongated hole 18b11 through at least two bolts that can be locked or unlocked.

[0121] Therefore, by adjusting the position of the active carriage movable mounting plate 18a3 on the active carriage base 18a1 and the position of the driven carriage movable mounting plate 18b3 on the driven carriage base 18b1, it can adapt to workpieces of different sizes and has good versatility.

[0122] Furthermore, in the active carriage fixed mounting plate 18a2 and the driven carriage fixed mounting plate 18b2, a bolt hole array composed of bolt holes distributed in an array is provided on one of them, and a slot hole array composed of slot holes distributed in an array is provided on the other, further improving the applicability to workpieces of different sizes.

[0123] In this embodiment, the slide table drive assembly includes a fifth rack 21 and two fifth linear guides 20 mounted in parallel on the slide table rail 17a, and a fifth motor 22 respectively mounted on the slide table 17b. The two slide tables 17b are respectively fixedly mounted on the corresponding sliders of the two fifth linear guides 20. Fifth drive gears 23 meshing with the fifth rack 21 are synchronously rotatably sleeved on the motor shafts of the fifth motors 22. Therefore, by driving the fifth drive gears 23 to rotate forward and backward, the motor shafts of the fifth motors 22 can drive the translation of the slide table 17b, and the control accuracy is high. Further, the fifth motor 22 is preferably a servo motor, which can further improve the precision control of the translation of the slide table 17b.

[0124] Please refer to Figure 2 and Figure 3, on one side of the sliding table track 17a near the side inlet / outlet 12d, there are two robotic arms 27. The two robotic arms 27 are relatively arranged on both sides of the two waste collection bins 25 and are adjacent to the corresponding sliding table inlet / outlet 12c respectively. When the active carriage 18a and the driven carriage 18b move to directly below the vision inspection assembly 26, the workpieces on the active carriage 18a and the driven carriage 18b can be grasped by the robotic arms 27. Specifically, the robotic arms 27 can both load and unload the workpieces on the sliding tables 17b at both ends of the sliding table track 17a, and when the active carriage 18a and the driven carriage 18b move to directly below the vision inspection assembly 26 and the workpieces are identified as having problems by the vision inspection assembly 26, according to the feedback data of the specific processing problems identified by the vision, if they cannot be reworked and repaired by the laser cutting head 5, they will be transported offline by the robotic arms 27 and stacked in the problem area, and the problem parts will be confirmed again by the workers uniformly, and manual or mechanical repair will be carried out.

[0125] Embodiment 2:

[0126] As Figure 1 shown, a multi-mode processing method for a double-station three-dimensional laser cutting system of Embodiment 1 is carried out according to the following steps:

[0127] S1. Identify the size of the workpiece to be processed in the workpiece stacking area 28 of the workpiece to be processed, and judge whether the size of the workpiece to be processed is greater than the set value: if yes, go to step S2; if no, go to step S4. That is: this step judges whether the workpiece to be processed needs to be placed on one sliding table 17b or two sliding tables 17b.

[0128] S2. Two sliding tables 17b that are not loaded with workpieces are simultaneously located outside one of the sliding table inlets / outlets 12c of the machine tool bed 12. After completion, proceed to the next step. In this step, if any one or both of the sliding tables 17b slide out from the sliding table inlet / outlet 12c and there are workpieces placed on them, the workpieces placed on them should be transported away by the robotic arm 27 first.

[0129] S3. A robotic arm 27 adjacent to the two sliding tables 17b transports a workpiece to be processed onto the two sliding tables 17b. After completion, go to step S6.

[0130] S4. An unloaded sliding table 17b is located outside one of the sliding table inlets / outlets 12c of the machine tool bed 12. After completion, proceed to the next step. In this step, if the sliding table 17b slides out from the sliding table inlet / outlet 12c and there is a workpiece placed on it, the workpiece placed on it should be transported away by the robotic arm 27 first.

[0131] S5. The robotic arm 27 adjacent to the unloaded sliding table 17b transports a workpiece to be processed onto the sliding table 17b. After completion, go to step S6.

[0132] S6. The sliding table 17b transfers the workpiece to be processed into the interior of the bed 12, and then the crossbeam module performs laser cutting on the workpiece. After completion, the next step is entered. In this step, either one crossbeam module is used to process the workpieces on two sliding tables 17b, or two crossbeam modules cooperate to process the workpieces on two sliding tables 17b. Specifically, when there is one workpiece on each of the two sliding tables 17b (the two workpieces can be the same or different), one crossbeam module can be used to process the workpieces on the two sliding tables 17b, or two crossbeam modules can be used to process the workpieces on the two sliding tables 17b; when a large workpiece is placed on two sliding tables 17b at the same time, one crossbeam module can be used to process the workpiece, or two crossbeam modules can cooperate to process the workpiece.

[0133] S7. During the process of transferring the processed workpiece to the side inlet / outlet 12d, the waste removal mechanism 24 removes the waste on the sliding table 17b into the waste collection box 25, and then the visual inspection component 26 detects whether the processed workpiece is qualified: if not, enter step S8; if so, enter step S10.

[0134] S8. Determine the repair method required for the unqualified part: if it requires the crossbeam module, return to step S6; if it requires manual operation, enter step S9.

[0135] S9. A robotic arm 27 adjacent to the unqualified part transfers the unqualified part to the unqualified part stacking area 29 for unified manual repair, and after completion, enter step S1.

[0136] S10. A robotic arm 27 adjacent to the qualified part transfers the qualified part to the qualified part stacking area 30, and after completion, enter step S1.

[0137] Therefore, by using the method of the present invention, not only does it have the function of alternately loading and unloading of the existing three-dimensional laser cutting machine, with high loading and unloading efficiency; but also, due to the provision of two crossbeam modules, through the one-to-one correspondence between the two crossbeam modules and the two sliding tables, it can not only process the same workpieces, but also each process a different workpiece, improving the flexibility of use; and, the two sliding tables can cooperate to load and unload outside a single sliding table inlet / outlet, and at the same time, the two crossbeam modules can cooperate to process a large workpiece, thus doubling the size limit for the workpiece to be processed and greatly improving the versatility of the equipment.

[0138] Finally, it should be noted that the above description is only the preferred embodiment of the present invention.
